Who can vote at the virtual Annual Meeting?

Only stockholders of record at the close of business on April 22, 2021, the record date for the Annual Meeting, and beneficial owners on the record date, who request and obtain a valid proxy from your broker, bank or other agent, will be entitled to vote at the Annual Meeting. As of April 22, 2021, there were 10,251,696 shares of common stock outstanding and entitled to vote. For ten days prior to the Annual Meeting, during normal business hours, a complete list of all stockholders on the record date will be available for examination by any stockholder at the Company’s offices at 1251 Waterfront Place, Suite 201, Pittsburgh, Pennsylvania 15222. The list of stockholders will also be available electronically during the Annual Meeting.

Stockholder of Record: Shares Registered in Your Name

If at the close of business on April 22, 2021 your shares were registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, then you are a stockholder of record. As a stockholder of record, you may vote at the virtual meeting or vote by proxy. Whether or not you plan to attend the virtual meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or through the Internet as instructed below to ensure your vote is counted.

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

If at the close of business on April 22, 2021 your shares were held in an account at a brokerage firm, bank, dealer or similar organization, rather than in your own name, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the virtual Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the virtual Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the virtual meeting unless you request and obtain a valid proxy from your broker, bank or other agent.

What am I voting on?

There are four matters scheduled for a vote:

1.To elect Norbert W. Young and Michael F. McNally as Class B members of our Board of Directors, each to serve for a three-year term;

2.To approve an amendment to the Limbach Holdings, Inc. Amended and Restated Omnibus Incentive Plan;

3.To hold a non-binding advisory vote on the compensation of our named executive officers; and,

4.To ratify the appointment of Crowe LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021.

What are the recommendations of our Board?

Unless you give other instructions on your proxy card, or by telephone or on the Internet, the persons named as proxy holders on the proxy card will vote in accordance with the recommendations of our Board. Our Board recommends a vote:

•FOR the election of the nominated slate of Class B directors (see Proposal 1);

•FOR the approval of an amendment to the Limbach Holdings, Inc. Amended and Restated Omnibus Incentive Plan (see Proposal 2);

•FOR the approval of the non-binding, advisory vote on the compensation of our named executive officers (see Proposal 3); and

•FOR the ratification of the appointment of Crowe LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021 (see Proposal 4).

What if another matter is properly brought before the meeting?

The Board knows of no other matters that will be presented for consideration at the virtual Annual Meeting. If you have submitted a proxy and any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his/her best judgment.

How do I vote?

For Proposal 1, you may either vote “For” all the nominees to be a Class B member of the Board or you may “Withhold” your vote for any one or more nominees you specify. For Proposal 2, Proposal 3, and Proposal 4 you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may vote at the virtual Annual Meeting by following the procedures set forth below, vote by proxy using the enclosed proxy card, vote by proxy over the telephone or vote by proxy through the Internet. Whether or not you plan to attend the virtual meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the virtual meeting and vote in person even if you have already voted by proxy.

•To vote at the virtual Annual Meeting we will give you an electronic ballot or such other procedures described by us.

•To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the virtual Annual Meeting, we will vote your shares as you direct.

•To vote by proxy over the telephone or by internet, follow the instructions on the proxy card you received. If voting by telephone or internet, your vote must be received by 11:59 p.m. EDT on June 14, 2021 to be counted.

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

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than from us. Simply complete and mail the proxy card to ensure that your vote is counted. Alternatively, you may vote by telephone or through the Internet as instructed by your broker or bank. To vote at the virtual Annual Meeting, you must obtain a legal proxy from your broker, bank, or other agent. Follow the instructions from your broker or bank included with these proxy materials, or contact your broker or bank to request a legal proxy.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you owned at the close of business on April 22, 2021.

What happens if I do not vote?

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the Internet or in person at the virtual Annual Meeting, your shares will not be voted, and your shares will count as “not present” for purposes of the establishment of a quorum for the meeting.

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

If you are a beneficial owner and do not instruct your broker, bank or other agent how to vote your shares, the question of whether your broker or nominee will still be able to vote your shares depends on whether the proposal is considered to be a “routine” matter.

See below under “What are broker non-votes?” for more information. At the virtual Annual Meeting, only Proposal 4 is considered a routine matter. Accordingly, without your instructions, your broker or nominee may not vote your shares on Proposal 1 or Proposal 2 or Proposal 3, but may vote your shares on Proposal 4.

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

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of the two nominees to our Board, “For” the approval of the amendment to the Limbach Holdings, Inc. Amended and Restated Omnibus Incentive Plan, “For” the approval of the non-binding, advisory vote on the compensation of our named executive officers, and “For” the ratification of the appointment of Crowe LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his/her best judgment.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. We have engaged The Proxy Advisory Group, LLC to assist in the solicitation of proxies and provide related advice and information support, for a service fee and the reimbursement of customary disbursements, which are not expected to exceed $15,000 in total.

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

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

Can I change my vote after submitting my proxy?

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

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

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

•You may send a timely written notice that you are revoking your proxy to our General Counsel at 1251

Waterfront Place, Suite 201, Pittsburgh, Pennsylvania 15222.

•You may attend the virtual Annual Meeting and vote there. Simply attending the virtual meeting will not,

by itself, revoke your proxy. Your most recent proxy card or telephone or Internet proxy is the one that is

counted.

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank for changing your vote.

When are stockholder proposals and director nominations due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 30, 2021 to our General Counsel at 1251 Waterfront Place, Suite 201, Pittsburgh, Pennsylvania 15222. All proposals must comply with Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which lists the requirements for the inclusion of stockholder proposals in company-sponsored proxy materials.

If you wish to submit a proposal to be acted on at next year’s annual meeting but not included in next year’s proxy materials, or if you wish to nominate a director, you must provide written notice as required by our bylaws no earlier than the opening of business on February 16, 2022 and no later than the close of business on March 18, 2022 to our General Counsel at 1251 Waterfront Place, Suite 201, Pittsburgh, Pennsylvania 15222. If next year’s annual meeting is called for a date that is before May 2, 2022 or after July 31, 2022, written notice of such proposal or nomination must be provided to our General Counsel at 1251 Waterfront Place, Suite 201, Pittsburgh, Pennsylvania 15222 no earlier than the opening of business on the 120th day before the date of next year’s annual meeting and no later than the later of (a) the close of business on the 90th day before next year’s annual meeting or (b) the close of business on the 10th day following the day on which public announcement of the date of next year’s annual meeting is first made by the Company.

You are also advised to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations.

How are votes counted?

Votes will be counted by the inspector of election appointed for the meeting, who will separately count, (i) for the election of directors (Proposal 1), votes “For,” “Withhold” and broker non-votes, (ii) for the approval of the amendment to increase the number of shares available under the Limbach Holdings, Inc. Amended and Restated Omnibus Incentive Plan (Proposal 2), votes “For,” “Against,” abstentions and, if applicable, broker non-votes, (iii) for the approval of the non-binding, advisory vote on the compensation of our named executive officers (Proposal 3), votes “For,” “Against,” abstentions and, if applicable, broker non-votes, and (iv) for the ratification of the appointment of our independent registered public accounting firm (Proposal 4), votes “For,” “Against,” abstentions and, if applicable, broker non-votes. Broker non-votes, if applicable, will have no effect on the outcome of Proposal 1. Abstentions and broker non-votes, if applicable, will not be counted towards the vote total for Proposal 2, Proposal 3 and Proposal 4 and thus will have no effect on the outcome of such proposals.

What are “broker non-votes”?

Under the rules of the New York Stock Exchange, your broker, bank, or nominee cannot vote your shares with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank or nominee. Proposal 1, Proposal 2 and Proposal 3 will be considered non-discretionary and therefore your broker, bank or nominee cannot vote your shares without your instruction. If you do not provide instructions with your proxy, your bank, broker, or other nominee may deliver a proxy card expressly indicating that it is NOT voting your shares; this indication that a bank, broker, or nominee is not voting your shares is referred to as a “broker non-vote.” Because banks, brokers and nominees are permitted to vote uninstructed shares on Proposal 4, broker non-votes will be counted for the purpose of determining the existence of a quorum at the virtual Annual Meeting, but will not count for purposes of determine the number of votes cast on Proposal 1, Proposal 2 or Proposal 3. You should instruct your broker to vote your shares in accordance with directions you provide.

How many votes are needed to approve each proposal?

•For Proposal 1, directors are elected by a plurality of the votes cast, which means that the two nominees for director receiving the most votes cast (from the holders of shares present in person or represented by proxy and entitled to vote on the election of directors) will be elected as Class B members of the Board. Only votes “For” will affect the outcome.

•To be approved, Proposal 2, the approval of an amendment to the Limbach Holdings, Inc. Amended and Restated Omnibus Incentive Plan, must receive “For” votes from the holders of a majority of the votes cast. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

•To be approved, Proposal 3, the approval of the non-binding, advisory vote on the compensation of our named executive officers, must receive “For” votes from the holders of a majority of the votes cast. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

•To be approved, Proposal 4, the ratification of the appointment of Crowe LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021, must receive “For” votes from the holders of a majority of the votes cast. Abstentions will have no effect on the outcome of this proposal.

What is the quorum requirement?

Holders of a majority of the voting power of the Company’s issued and outstanding capital stock entitled to vote at the virtual Annual Meeting, present in person or represented by proxy, constitute a quorum. In the absence of a quorum, the chairman of the virtual Annual Meeting will have the power to adjourn the Annual Meeting.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement.

How do I submit questions to be answered during the question and answer session?

Prior to the Annual Meeting, stockholders may submit any questions in advance through https://viewproxy.com/limbach/2021/. Additional information regarding the ability of stockholders to ask questions during the 2021 Annual Meeting, related rules of conduct and other materials for the 2021 Annual Meeting will be available at https://viewproxy.com/limbach/2021/. We have created and implemented the virtual format in order to facilitate stockholder attendance and participation by enabling stockholders to participate fully, and equally, from any location around the world, at no cost. However, you will bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies. A virtual Annual Meeting makes it possible for more stockholders (regardless of size, resources or physical location) to have direct access to information more quickly, while saving the company and our stockholders time and money, especially as physical attendance at meetings has dwindled. We also believe that the online tools we have selected will increase stockholder communication. For example, the virtual format allows stockholders to communicate with us in advance of, and during, the Annual Meeting so they can ask questions of our board of directors or management. During the

live Q&A session of the Annual Meeting, we may answer questions as they come in and address those asked in advance, to the extent relevant to the business of the Annual Meeting, as time permits.

Both stockholders of record and street name stockholders will be able to attend the Annual Meeting via live audio webcast, submit their questions during the meeting and vote their shares electronically at the Annual Meeting.

What do I do if I need technical assistance to access the Annual Meeting?

We encourage you to access the Annual Meeting prior to the start time. Online check-in will begin at 8:30 a.m. EDT, and you should allow ample time for the check-in procedures. We will have technicians ready to assist you with any technical difficulties before the virtual Annual Meeting begins. Stockholders of record and beneficial owners should call Alliance Advisors at 1-866-612-8937 with any questions about attending the virtual Annual Meeting. If you encounter any difficulty accessing the virtual Annual Meeting, please e-mail virtualmeeting@viewproxy.com for assistance.

The virtual Annual Meeting platform is fully supported across browsers (Internet Explorer, Firefox, Chrome and Safari) and devices (desktops, laptops, tablets and cell phones) running the most updated version of applicable software and plugins. Participants should ensure that they have a strong Internet connection wherever they intend to participate in the Annual Meeting. Participants should also give themselves plenty of time to log in prior to the start of the Annual Meeting. FAQs will be made available prior to the Annual Meeting at https://viewproxy.com/limbach/2021/.

It is important that you review the proxy materials for the Annual Meeting previously distributed to you. Whether or not you plan to attend the virtual-only Annual Meeting, we encourage you to vote your shares of common stock in advance of the Annual Meeting using one of the voting methods described in the proxy materials.

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

Preliminary voting results may be announced at the virtual Annual Meeting. In addition, final voting results will be published in a Current Report on Form 8-K (a “Form 8-K”) that we expect to file with the U.S. Securities and Exchange Commission (the “SEC”) within four business days after the virtual Annual Meeting. If final voting results are not available to us in time to file a Form 8-K, within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

What proxy materials are available on the Internet?

The Notice of Annual Meeting and Proxy Statement and 2020 Annual Report are available on our website at www.limbachinc.com under “Investor Relations — Financial Information”.

PROPOSAL 1

ELECTION OF DIRECTORS

Our Board currently consist of seven directors and is divided into three classes. The term of each directorship is three years, so that one class of directors is elected each year. All directors are elected for three-year terms and until their successors are elected and qualified, or, if sooner, until the director’s death, resignation or removal.

At the virtual Annual Meeting, our stockholders will vote to elect two current Class B directors, Norbert W. Young and Michael F. McNally. The Class B directors will have a term expiring at the 2024 Annual Meeting of Stockholders. Information concerning each nominee for director is set forth below under “Directors and Executive Officers.”

Directors are elected by a plurality of the votes cast. The two nominees for director receiving the most votes cast “FOR” such director (from the holders of shares present virtually or represented by proxy and entitled to vote on the election of directors) will be elected.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Director Independence

Pursuant to Nasdaq listing standards, a majority of the members of our Board must qualify as “independent,” as affirmatively determined by our Board. Consistent with this requirement, based on the review and recommendation of our Nominating and Corporate Governance Committee, our Board reviewed the relevant identified transactions or relationships between each of our directors, or any of their family members, and us, our senior management and our independent registered public accounting firm, and has affirmatively determined that each of Messrs. Swets, McNally, Pratt, Young and Horowitz and Ms. Krzeminski meets the standards of independence under the applicable Nasdaq listing standards. In making this determination, our Board found all of our directors (other than Mr. Bacon, our President and Chief Executive Officer) to be free of any relationship that would impair his or her individual exercise of independent judgment with regard to us. Our Board has also determined that each member of its Audit Committee, Compensation Committee, Nominating and Corporate Governance Committee and Executive Committee and Finance is independent under Nasdaq Rule 5605(a)(2).

Board Leadership Structure

Our Board believes it is important to maintain flexibility as to the Board’s leadership structure, but supports maintaining a non-management director in a leadership role at all times, whether as non-executive Chairman or Lead Director. Under our current structure, Mr. Pratt serves as non-executive Chairman and as such we do not have a Lead Director. As Chairman of our Board, Mr. Pratt has the authority, among other things, to call and preside over Board meetings, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board.

We believe that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board in its oversight of our business and affairs and is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of us and our stockholders.

Role of the Board in Risk Oversight

One of the Board’s key functions is informed oversight of our risk management process. The Board directly oversees our risk management function as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, while our Board is responsible for monitoring and assessing strategic risk exposure, our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. Our Audit Committee also monitors compliance with legal and regulatory requirements. Our Compensation Committee, together with its independent compensation consultant, Aon, assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board. The Chairman has the responsibility of coordinating between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

Meetings of the Board of Directors

Our business, property and affairs are managed under the supervision of our Board. Members of our Board are kept informed of our business through discussions with our President and Chief Executive Officer and other officers and employees, by reviewing materials provided to them during visits to our offices and by participating in meetings of the Board and its committees.

The Board held a total of 13 meetings in 2020. The standing committees of the Board are the Audit Committee, the Compensation Committee, the Nominating and Corporate Governance Committee, the Executive Committee and the Finance and Capital Markets Committee. The charter for each of our standing Board committees is posted on our website at www.limbachinc.com under “Investor Relations — Corporate Governance — Governance Documents”. All directors attended 75% or more of the combined total number of meetings of the Board and each of the Board committees on which they served during 2020. Our Board is also encouraged to attend our annual meetings of stockholders. Two of our directors attended our 2020 Annual Meeting. The Board also has regularly scheduled executive sessions, including as part of the Executive Committee meetings, at which only independent directors are present.

The following table provides membership and meeting information for 2020 for each of our Board committees:

The functions of our Nominating and Corporate Governance Committee include:

Executive Committee

The Executive Committee is responsible for providing an efficient means of considering matters that arise between regularly scheduled Board meetings and are such that they (i) require prompt attention or (ii) are deemed appropriate by the members of the Executive Committee for consideration on behalf of the Board, including the preliminary screening, discussion and in-depth deliberation of matters that are or may be brought before the full Board for approval. The members of the Executive Committee are each of the chairpersons of the other standing committees.

commitments and asset disposals not previously approved by the Board as part of the annual plan.

Director Nominations

The Board has delegated to the Nominating and Corporate Governance Committee the responsibility of identifying, screening and recommending candidates to the Board. Potential candidates are interviewed by the Chairman and Chief Executive Officer and the Chair of the Nominating and Corporate Governance Committee prior to their nomination, and may be interviewed by other directors and members of senior management. The Nominating and Corporate Governance Committee then meets to consider and approve the final candidates, and either makes its recommendation to the Board to fill a vacancy, add an additional member, or recommend a slate of candidates to the Board for nomination for election to the Board. The selection process for candidates is intended to be flexible, and the Nominating and Corporate Governance Committee, in the exercise of its discretion, may deviate from the selection process when particular circumstances warrant a different approach.

The Nominating and Corporate Governance Committee will consider candidates proposed by stockholders to be potential director nominees. Stockholders wishing to nominate a candidate for consideration by the Nominating and Corporate Governance Committee as a director nominee should provide the name of any recommended candidate, together with a brief biographical sketch, a document indicating the candidate’s willingness to serve, if elected, and evidence of the nominating stockholder’s ownership of Company stock to the attention of the General Counsel of the Company at 1251 Waterfront Place, Suite 201, Pittsburgh, Pennsylvania 15222, and otherwise follow the Company’s nominating process summarized above under “Questions and Answers about these Proxy Materials and Voting — When are stockholder proposals and director nominations due for next year’s annual meeting?” and more fully described in the Company’s bylaws. The Nominating and Corporate Governance Committee’s policy is to evaluate director nominees proposed by stockholders in the same manner that all other director nominees are evaluated. The general criteria the Nominating and Corporate Governance Committee considers important in evaluating director candidates are: (i) senior-level management and decision-making experience; (ii) a reputation for integrity and abiding by exemplary standards of business and professional conduct; (iii) ability to devote time and attention necessary to fulfill the duties and responsibilities of a director; (iv) a record of accomplishment in their respective fields, with leadership experience in a corporation or other complex organization, including government, educational and military institutions; (v) independence and the ability to represent all of the Company’s stockholders; (vi) compliance with legal and Nasdaq listing requirements; (vii) sound business judgment; (viii) candor; (ix) judgment, skills, geography and other measures to ensure that the Board as a whole reflects a range of viewpoints, backgrounds, skills, experience and expertise; and (x) the needs of the Board among others. The Nominating and Corporate Governance Committee seeks to have a Board that reflects diversity

in background, education, business experience, gender, race, ethnicity, culture, skills, business relationships and associations and other factors that will contribute to the Board’s governance of the Company, and reviews its effectiveness in achieving such diversity when assessing the composition of the Board.

The Company may, in the future, pay a third-party a fee to assist it in the process of identifying and/or evaluating director candidates.

Securityholder Communications with the Board

Securityholders who wish to communicate with the Board or an individual director may send a written communication to the Board or such director addressed to our General Counsel at 1251 Waterfront Place, Suite 201, Pittsburgh, Pennsylvania 15222. Each communication must set forth:

•the name and address of the securityholder on whose behalf the communication is sent; and

•the number of our shares that are owned beneficially by such securityholder as of the date of the communication.

Each communication will be reviewed by our General Counsel to determine whether it is appropriate for presentation to the Board or such director. Examples of inappropriate communications include advertisements, solicitations or hostile communications. Communications determined by our General Counsel to be appropriate for presentation to the Board or such director will be submitted to the Board Chairman, the Board or such director on a periodic basis.

Code of Ethics

We have adopted a code of ethics that applies to all of our employees, officers and directors, including those officers responsible for financial reporting. The code of ethics is available on our website at www.limbachinc.com under “Investor Relations — Corporate Governance — Governance Documents.”

Director Compensation

We have adopted a compensation program for non-employee directors. The non-employee director compensation program is intended to fairly compensate each of our non-employee directors with cash and equity compensation for the time and effort necessary to serve as a member of our Board.

Cash compensation. The compensation policy for board service remained the same in 2020; however, during the second quarter of 2020 board fees were reduced 10% as a cost reduction measure. As a result, our non-employee directors received annual cash compensation of $58,500 in 2020 year for their services on the Board. In addition, the Chair of the Board received a cash retainer of $48,750; the Chair of the Audit Committee received a cash retainer of $39,000, the Chair of the Finance and Capital Markets Committee received a cash retainer of $39,000 and the Chair of the Nominating and Corporate Governance Committee and Chair of the Compensation Committee each received a cash retainer of $19,500. All payments are made in arrears. If requested, all director expenses incurred in attending the Board of Directors or committee meetings are reimbursed by the Company. Mr. Bacon, the Company’s President and Chief Executive Officer, does not receive compensation for serving as a member of the Board of Directors.

Equity compensation. Our non-employee directors are eligible to receive equity-based awards as compensation for their services as directors. Our non-employee directors are typically granted 3,200 RSUs on January 1 each year. These RSUs are subject to service-based vesting conditions and vest in equal annual installments on each of the first three successive anniversaries of the grant date. New non-employee director’s RSUs awards are prorated based on the date the director is either elected or appointed to the board.

The table below provides summary information concerning compensation paid or accrued by us to or on behalf of our non-executive directors for services rendered for the fiscal year ended December 31, 2020.

Compensation Determinations

This section explains the compensation provided to our named executive officers in 2020. Our Compensation Committee is charged with recommending executive compensation packages to our Board. As part of this process, the Compensation Committee, or in the case of the CEO, the members of the Board other than the CEO, evaluate the performance of our executive officers each year. The Compensation Committee has retained Aon to serve as its independent executive compensation consultant. Aon regularly attends committee meetings and assists and advises the Committee in connection with its review of executive compensation policies and practices, including Board of Director compensation and fees. In particular, Aon provides market data, trends and analysis regarding our executive compensation in comparison to its peers to assist the Committee in its decision-making process. The Committee reviews and confirms the independence of Aon on an annual basis. Aon also performs services related to education of our employees in connection with our Employee Stock Purchase Plan.

Base Salary

The Compensation Committee is responsible for determining the base salaries for each of the named executive officers (“NEOs”), consistent with the employment arrangements referenced below. Annual base salaries are paid in cash and the amounts are reviewed annually by the Compensation Committee whereupon recommendations of increases were made after such evaluations.

Cash Incentive Arrangements

In 2020, our NEOs were provided cash bonuses. The bonus for Fiscal 2020 was designed to focus our named executive officers on driving future growth and profitability. Specifically, this program was designed to reward our named executive officers if the Company were to achieve pre-determined Adjusted EBITDA, working capital and individual strategic performance goals, subject to the Company’s standard clawback provisions. Target annual incentive opportunities are expressed as a percentage of base salary, and were established based on the NEO’s level of responsibility and his or her ability to impact overall results. The Compensation Committee also considers market data in setting target award amounts. Target award bonus percentages for Fiscal 2020 for Messrs. Bacon and McCann and Mrs. Brooks were 100%, 70%, and 60%, respectively. The Executive’s total bonus is capped at one times his or her annual base salary. The Committee, however, has the discretion to permit bonus payments in excess of one times base salary as long as the Company’s Corporate EBITDA margin is greater than 5%. The weightings for the performance measures for Fiscal 2020 are set forth in the table below.


Named Executive Officer	Adjusted EBITDA	Working Capital	Individual strategic performance goals
Charlie A. Bacon, III	70%	15%	15%
Jayme L. Brooks	70%	15%	15%
Michael M. McCann	70%	15%	15%

RSU Grants Under the Limbach Holdings, Inc. Omnibus Incentive Plan

The Company maintains the Limbach Holdings, Inc. Amended and Restated Omnibus Incentive Plan (the “Omnibus Plan”), pursuant to which the Company may grant equity awards. The principal purposes of the Omnibus Plan are to encourage profitability and growth through short-term and long-term incentives that are consistent with the Company’s objectives; to give participants an incentive for excellence in individual performance; to promote teamwork among participants; and to give the Company a significant advantage in attracting and retaining key employees, directors, and consultants. As noted in the Outstanding Equity Awards at 2020 Year-End table below, in 2020, the Company made grants of service-based and performance-based RSUs to its named executive officers.

In discharging its responsibility for administering the Company’s stock-based compensation programs, the Compensation Committee regularly monitors and evaluates the total cost of such programs, based on information provided annually by, and in consultation with Aon, the Company’s independent compensation consultant. This information includes share utilization and annual grant levels. The Compensation Committee determines the appropriate award to each NEO by assessing equity incentive awards made to officers of comparable companies.

Long-term incentive awards are designed to keep senior executives focused on the execution of longer-term financial and strategic growth goals that drive stockholder value creation, as well as support the Company’s leadership retention strategy. In furtherance of these goals, the Compensation Committee determined that equity-based compensation for Fiscal 2020 should be comprised of a mix of PRSUs and RSUs. At the beginning of Fiscal 2020, Messrs. Bacon and McCann and Ms. Brooks’ target long-term incentive amounts were set at 17,500, 10,000 and 10,000 PRSUs, respectively. The remainder of the annual long-term incentives are in the form of RSUs that were granted on January 1, 2020, which vest in annual increments of 33.33% over three years on each anniversary of the date of grant. On May 11, 2020, in recognition of his promotion to Chief Operating Officer, Mr. McCann received an additional grant of 7,500 RSUs and 7,500 PRSUs, which vest in equal annual increments over three years on January 1, 2021, January 1, 2022 and January 1, 2023.

SECURITY OWNERSHIP OF

CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information known to the Company regarding beneficial ownership of shares of the Company’s common stock as of April 22, 2021, by:

•each person who is known to us to be the beneficial owner of more than 5% of the outstanding

shares of the Company’s common stock;

•each named executive officer and each director and nominee; and

•all of the Company’s executive officers and directors and nominees as a group.

The amounts and percentages of shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities for which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Beneficial ownership of the company’s common stock is based on 10,251,696 shares of the Company’s common stock issued and outstanding as of April 22, 2021.

Except as otherwise indicated in these footnotes, each of the beneficial owners listed has, to our knowledge, sole voting and investment power with respect to the indicated shares of common stock. Addresses for the beneficial owners are set forth in the footnotes to the table.

PROPOSAL 2

APPROVAL OF AN AMENDMENT TO THE LIMBACH HOLDINGS, INC.

AMENDED AND RESTATED OMNIBUS INCENTIVE PLAN

The Limbach Holdings, Inc. Amended and Restated Omnibus Incentive Plan (the “Omnibus Plan”) was originally adopted by our Board of Directors on August 30, 2017. On April 19, 2019, our Board of Directors approved amendment no. 1 to the Omnibus Plan (“Amendment No. 1”), which was approved by the stockholders on May 30, 2019. On March 11, 2020, our Board of Directors approved, Amendment No. 2 (“Amendment No. 2”) to the Omnibus Plan, which was approved by the stockholders on July 14, 2020. On March 9, 2021, our Board of Directors approved Amendment No. 3 (“Amendment No. 3”) to the Omnibus Plan subject to stockholder approval, to increase the aggregate number of shares of common stock authorized for issuance under the Omnibus Plan by 600,000 and extend the plan term so that it will expire on June 16, 2031 and is submitting the Amendment No. 3 to the stockholders for approval at the annual meeting.

The Board of Directors believes that stock-based incentive awards can play an important role in the success of the company by encouraging and enabling the employees, officers, non-employee directors and consultants of the company and its subsidiaries upon whose judgment, initiative and efforts the company largely depends for the successful conduct of its business to acquire a proprietary interest in the company. The Board of Directors believes that providing such persons with a direct stake in the company assures a closer identification of the interests of such individuals with those of the company and its stockholders, thereby stimulating their efforts on the company’s behalf and strengthening their desire to remain with the company. Amendment No. 3 is designed to enhance the flexibility to grant equity awards to our officers, employees, non-employee directors and consultants at levels determined to be appropriate by the Board of Directors and the Compensation Committee to motivate, attract and retain the services of such individuals and align their financial interests with those of our stockholders. A copy of the Omnibus Plan, as proposed to be amended by Amendment No. 3 is attached as Appendix A to this proxy statement and is incorporated herein by reference.

Summary of the material features of the Omnibus Plan, as proposed to be amended by Amendment No. 3

Share Reserve Increase. The Omnibus Plan provides a range of incentive tools and sufficient flexibility to permit the Compensation Committee to implement it in ways that will make the most effective use of the shares of common stock that the Company’s stockholders authorize for incentive purposes. The Board determined that increasing the shares of common stock reserved for issuance under the Omnibus Plan is necessary for the Company to continue to offer a competitive equity incentive program, and thus, the Board approved Amendment No. 3, which increases by 600,000 the number of shares of common stock that may be issued pursuant to awards under the Omnibus Plan, subject to approval by our stockholders at the Annual Meeting. On April 22, 2021, the closing price of a share of our common stock reported on Nasdaq was $10.13.

The following table summarizes information regarding awards outstanding and shares of our Common Stock remaining available for grant as of April 22, 2021:


Stock Options Outstanding			0 shares
Weighted Average Exercise Price of Stock Options Outstanding			n/a
Weighted Average Remaining Term of Stock Options Outstanding			n/a
Full Value Awards Outstanding (RSUs, MRSUs and PRSUs)			819,449 shares
Shares Available for Grant under the Omnibus Plan			285,501 shares

Based solely on the closing price of common stock as reported by Nasdaq on April 22, 2021 and the maximum number of shares that would have been available for awards as of such date under the Omnibus Plan, the maximum aggregate market value of the common stock that could potentially be subject to new awards under the Omnibus Plan was $11.2 million.

Rationale for share increase

Amendment No. 3 is critical to our ongoing effort to build stockholder value. Equity awards are an important component of our executive and non-executive employee compensation programs. Our Board of Directors and Compensation Committee believe that we must continue to offer a competitive equity compensation program in order to attract, retain and motivate the talented and qualified employees necessary for our continued growth and success. Our Compensation Committee determined the size of the proposed increase under Amendment No. 3 based on projected equity awards to anticipated new hires, projected annual equity awards to existing employees and an assessment of the magnitude of increase that our institutional investors would likely find acceptable.

We manage our long-term stockholder dilution by limiting the number of equity incentive awards granted annually. This includes an equity-based compensation design that emphasizes a mix of time-based restricted stock units (“RSUs”) and performance-based restricted stock units (“PRSUs”), versus more dilutive stock options. The Compensation Committee carefully monitors our annual net burn rate, total dilution and equity expense in determining the number of awards it grants. Our compensation philosophy reflects broad-based eligibility for equity incentive awards for high performing employees. By doing so, we link the interests of those employees with those of our stockholders and motivate our employees to act as owners of the business.

Burn rate. Burn rate, which is the rate at which companies use shares available for grant under their equity compensation plans, is an important factor for investors concerned about stockholder dilution. In setting and recommending to stockholders the number of additional shares to be authorized under the Omnibus Plan upon adoption of Amendment No. 3, the Compensation Committee and the Board of Directors considered the company’s burn rates for all grants of equity awarded by the Board of Directors for the past three fiscal years ended December 31, 2020, 2019 and 2018. The following table sets forth information regarding historical awards granted for the fiscal years ended December 31, 2020, 2019 and 2018, and the corresponding net burn rate. The net burn rate is calculated by adding options and full value awards granted, less any options and full-value awards forfeited, cancelled, or expired, divided by the weighted average shares outstanding. Our three-year average net burn rate is 4.49%.


	Fiscal Year
Share Element	2020		2019		2018
Stock Options Granted	—		—		—
Full-Value Awards Granted(1)	275,133		274,851		142,881
Less: Stock Options Forfeited, Cancelled or Expired	91,916		93,232		18,118
Less: Full-Value Awards Cancelled	—		—		—
Net Awards Granted(2)	183,217		181,619		124,763
Weighted average common shares outstanding during the fiscal year	7,865,089		7,662,362		7,562,586
Annual Net Burn Rate	5.25	%	5.38	%	2.83	%
Three Year Average Net Burn Rate	4.49	%

(1) Full value awards granted consist of RSUs, MRSUs and PRSUs.

(2) Net Awards Granted represent the sum of Stock Options Granted and Full-Value Awards Granted, less Stock Options and Full-Value Awards that forfeited, cancelled or expired.

As of December 31, 2020, there were no stock options outstanding under our equity compensation plan. In addition, as of December 31, 2020, there were 285,799 unvested full value awards with time-based vesting and 202,000 unvested full value awards with performance vesting outstanding under our equity compensation plans. Other than the foregoing, no awards under our equity compensation plans were outstanding as of December 31, 2020. As of December 31, 2020, there were 670,784 shares were available for future awards under the Omnibus Plan, as amended by Amendment No. 2.

Summary of the Omnibus Plan

The following description of certain features of the Omnibus Plan is intended to be a summary only. The summary is qualified in its entirety by the full text of the Omnibus Plan, as proposed to be amended by Amendment No. 3, which is attached as Appendix A to this proxy statement and incorporated herein by reference.

The principal purposes of the Omnibus Plan are to encourage profitability and growth through short-term and long-term incentives that are consistent with the Company’s objectives; to give participants an incentive for excellence in individual performance; to promote teamwork among participants; and to give the Company a significant advantage in attracting and retaining key employees, directors, and consultants. The Omnibus Plan provides for the grant of incentive stock options within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), nonqualified stock options, stock appreciation rights, restricted shares, restricted stock units, performance-based awards (including performance-based restricted shares and performance units), and other stock or cash-based awards. When considering new grants of share-based or option-based awards, we intend to take into account previous grants of such awards.

Administration. The Omnibus Plan is administered by our Compensation Committee (referred to below as the plan administrator). The plan administrator has the power to determine the terms of the awards granted under the Omnibus Plan, including the exercise price, the number of shares subject to each award, and the exercisability of the awards. The plan administrator also has full power to determine the persons to whom and the time or times at which awards will be made and to make all other determinations and take all other actions advisable for the administration of the Omnibus Plan.

Extension of Plan Term. The Board also approved an extension of the term of the Omnibus Plan so that it will now expire on June 16, 2031, the tenth anniversary of the date that stockholders approve Amendment No. 3 to the Omnibus Plan.

No “Liberal” Share Recycling for Any Awards. The Omnibus Plan does not allow the recycling of shares tendered to cover the exercise price or withheld to cover taxes upon the exercise of stock options and stock appreciation rights or any shares tendered or withheld to cover taxes on restricted shares, restricted stock units, performance-based awards and other stock-based awards.

No Dividends or Dividend Equivalents Paid on Unvested Awards. To the extent that any award under the Omnibus Plan contains a right to receive dividends or dividend equivalents while such award remains unvested, such dividends or dividend equivalents will be accumulated and paid when, and to the extent that the underlying award vests.

No Repricing of Options or Stock Appreciation Rights. The Omnibus Plan prohibits the repricing of stock options and stock appreciation rights and cash buyouts of underwater options and stock appreciation rights without stockholder approval.

Eligible Participants. Certain employees, directors and consultants are eligible to be granted awards under the Omnibus Plan, other than incentive stock options, which may be granted only to employees. There are currently approximately 1,500 employees, six non-employee directors, and zero consultants who would potentially be eligible to receive awards under the Omnibus Plan.

Shares Available for Awards; Award Limits. If stockholders approve the amendment to the Omnibus Plan, the number of shares available for future awards after such approval will be the sum of (i) 600,000, (ii) the number of shares available for the grant of future awards under the Omnibus Plan immediately before the Annual Meeting, and (iii) the number of shares subject to awards outstanding on the date of the Annual Meeting that are thereafter forfeited, terminated or cancelled (as of April 22, 2021, 537,549 shares were subject to outstanding awards.) . The number of shares issued or reserved pursuant to the Omnibus Plan will be adjusted by the plan administrator, as they deem appropriate and equitable, as a result of stock splits, stock dividends, and similar changes in our common stock. With respect to any one participant, no more than (i) 400,000 shares of our common stock will be granted in a fiscal year, (ii) $2,000,000 will be paid in cash with respect to a performance period of one year, and (iii) $500,000 will be paid in cash with respect to a performance period greater than one year. In addition, the maximum number of shares subject to awards granted during any fiscal year to any non-employee director, taken together with any cash fees paid to such non-employee director during the fiscal year, will not exceed $500,000 in total value (calculating

the value of any such awards based on the grant date fair market value of such awards for financial reporting purposes).

Any shares of common stock subject to an award under the Omnibus Plan that are forfeited, cancelled, settled or otherwise terminated without a distribution of shares of common stock to a participant will thereafter be deemed to be available for awards. However, none of the following shares of common stock will be added back to the shares authorized for grant under the Omnibus Plan: (i) shares otherwise issuable or issued in respect of an award that are withheld to cover taxes or any applicable exercise price, (ii) shares subject to share-settled stock appreciation rights or options that are exercised, or (iii) shares tendered to exercise outstanding options or other awards or to cover applicable taxes on such awards.

Minimum Vesting Requirement. Except in the case of substitute awards, awards granted under the Omnibus Plan will be subject to a minimum vesting period of one year from the date of grant. Notwithstanding the foregoing, the plan administrator may provide that the vesting of an award will accelerate in the event of a participant’s death, disability, retirement or a change in control, and the plan administrator may grant awards covering 5% of the shares of common stock reserved for issuance under the Omnibus Plan without regard to the minimum vesting provision. The vesting of any unvested awards granted to non-employee directors will be deemed to satisfy the one-year minimum vesting provision if the awards vest on the earlier of the one-year anniversary of the date of grant and the next regular annual meeting of stockholders that is at least 50 weeks after the immediately preceding year’s annual meeting.

Stock Options. Under the Omnibus Plan, the plan administrator may grant participants incentive stock options, which qualify for special tax treatment in the United States, as well as non-qualified stock options. Stock options are a variable component of compensation designed to incentivize the participants to grow the Company and to increase the value of our shares. The plan administrator will establish the duration of each option at the time it is granted, with a maximum duration of 10 years (or in the case of a ten percent (10%) stockholder within the meaning of Section 422(b)(6) of the Internal Revenue Code, five years) from the date such option is granted, and may also establish vesting performance requirements that must be met prior to the exercise of options. Stock option grants must have an exercise price that is equal to or greater than the fair market value of our common stock on the date of grant. Stock option grants may include provisions that permit the option holder to exercise all or part of the holder’s vested options, or to satisfy withholding tax liabilities, by tendering shares of our common stock already owned by the option holder with a fair market value equal to the exercise price. Dividends may not be paid on awards of stock options under the Omnibus Plan.

Stock Appreciation Rights. The plan administrator may also grant stock appreciation rights, which will be exercisable upon the occurrence of certain contingent events. Stock appreciation rights are a variable component of compensation designed to retain key employees. Stock appreciation rights entitle the holder upon exercise to receive an amount in any combination of cash and shares of our common stock (as determined by the plan administrator) equal in value to the excess of the fair market value of the shares covered by the stock appreciation rights over the exercise price of the right.

Restricted Shares. The plan administrator may also grant restricted shares, which are awards of our shares of common stock that vest in accordance with the terms and conditions established by the plan administrator. The plan administrator will determine in the award agreement whether the participant will be entitled to vote the restricted shares or receive dividends on such share (subject to the requirement that dividends cannot be paid on restricted shares until the shares vest). Restricted shares are a variable component of compensation also available to retain key employees when deemed appropriate.

Restricted Stock Units. Restricted stock units represent the right to receive shares of our common stock at a specified date in the future, subject to forfeiture of such right. If the restricted stock units have not been forfeited, then on the date specified in the award agreement, we must deliver to the holder of the restricted stock units, unrestricted shares of our common stock, which will be freely transferable. Restricted stock units are a variable component of compensation also designed to retain key employees when deemed appropriate.

Performance-Based Awards. Performance-based awards are denominated in shares of our common stock, stock units, or cash, and are linked to the satisfaction of performance criteria established by the plan administrator. Performance-based awards are a variable component of compensation designed to reward key management for achieving performance goals. The performance-based criteria applicable to such awards shall be determined by

reference to any one or more of the following: earnings before interest and taxes; earnings before interest, taxes, depreciation and amortization; net operating profit after tax; cash flow; revenue; net revenues; sales; days sales outstanding; scrap rates; income; net income; operating income; net operating income, operating margin; earnings; earnings per share; return on equity; return on investment; return on capital; return on assets; return on net assets; total stockholder return; economic profit; market share; appreciation in the fair market value, book value or other measure of value of our common stock; expense/cost control; working capital; volume/production; new products; customer satisfaction; brand development; employee retention or employee turnover; employee satisfaction or engagement; environmental, health, or other safety goals; individual performance; strategic objective milestones; days inventory outstanding; any other criteria specified by the plan administrator in its sole discretion; or any combination of, or a specified increase in, any of the foregoing.

Other Awards. In addition to the awards described above, the plan administrator may grant other incentives payable in cash or shares of common stock under the Omnibus Plan as it deems consistent with the terms of the Omnibus Plan and subject to such other terms and conditions as it deems appropriate.

Dividends and Dividend Equivalents. To the extent that any award under the Omnibus Plan contains a right to receive dividends or dividend equivalents while such award remains unvested, notwithstanding anything in the Omnibus Plan to the contrary, such dividends or dividend equivalents will be accumulated and paid when and to the extent that the underlying award vests.

Change in Control Provisions. In connection with the grant of an award, the plan administrator may provide for the treatment of such award in the event of a change in control of the Company, including that, in the event of an involuntary termination of a participant’s employment by the Company in connection with a change in control, any outstanding awards that are unexercisable or otherwise unvested will become fully vested and/or immediately exercisable.

Amendment and Termination. Our Board of Directors, or a committee thereof, may alter, amend, modify, or terminate the Omnibus Plan at any time; provided that the approval of our stockholders will be obtained for any amendment to the Omnibus Plan that requires stockholder approval under the rules of the stock exchange on which our common stock is then listed or in accordance with other applicable law. In addition, without stockholder approval, to the extent required by the rules of the stock exchange(s) on which the shares of common stock are traded, except as otherwise permitted under the “equitable adjustments” provisions of the Omnibus Plan, (i) no amendment or modification may reduce the exercise price of any stock option or stock appreciation right, (ii) the Compensation Committee may not cancel any outstanding stock option or stock appreciation right and replace it with a new option or stock appreciation right, another award or cash and (iii) the Compensation Committee may not take any other action that is considered a “repricing” for purposes of the stockholder approval rules of the applicable stock exchange(s). No modification of an award will, without the prior written consent of the participant, impair the rights of a participant under the Omnibus Plan.

Compliance with Applicable Laws. We intend for awards granted under the Omnibus Plan to be designed, granted, and administered in such a manner that they are either exempt from the application of, or comply with, the requirements of Section 409A of the Internal Revenue Code.

New Plan Benefits Under the Omnibus Plan. Future awards under the Omnibus Plan will be made at the discretion of the plan administrator based on such factors as the plan administrator deems relevant at the time the awards are made.

Summary of Federal Income Tax Consequences

The following is a brief description of the federal income tax treatment that generally applies to Omnibus Plan awards. The description is based on current federal tax laws, rules and regulations, which are subject to change, and does not purport to be a complete description of the federal income tax aspects of the Omnibus Plan. A participant may also be subject to state, local and foreign taxes.

Non-Qualified Stock Options. The grant of a non-qualified stock option will not result in taxable income to the participant. The participant will realize ordinary income at the time of exercise in an amount equal to the excess, if any, of the then fair market value of the stock acquired over the exercise price for those shares, and the Company will be entitled to a corresponding deduction. Gains or losses realized by the participant upon disposition of such

shares will be treated as capital gains or losses, with the basis in such stock equal to the fair market value of the shares at the time of exercise.

Incentive Stock Options. The grant of an incentive stock option will not result in taxable income to the participant. The exercise of an incentive stock option will not result in taxable income to the participant if the participant was continuously employed by the Company or an affiliate from the date of the grant of the option until the date three months prior to the date of exercise (one year prior to the date of exercise if the participant is disabled). The excess, if any, of the fair market value of the stock at the time of the exercise over the exercise price is an adjustment that is included in the calculation of the participant’s alternative minimum taxable income for the tax year in which the incentive stock option is exercised.

If the participant does not sell or otherwise dispose of the stock within two years from the date of the grant of the incentive stock option or within one year after the transfer of such stock to the participant, then, upon disposition of such stock, any amount realized in excess of the exercise price will be taxed to the participant as capital gain, and the Company will not be entitled to a corresponding deduction. If the holding period requirements are not met, the participant will generally realize ordinary income at the time of the disposition of the shares, in an amount equal to the lesser of (i) the excess, if any, of the fair market value of the stock on the date of exercise over the exercise price, or (ii) the excess, if any, of the amount realized upon disposition of the shares over the exercise price, and the Company will be entitled to a corresponding deduction. In addition, the participant will recognize capital gain or loss equal to the difference between the amount realized and the value of the shares on the date of exercise.

Stock Appreciation Rights. The grant of a stock appreciation right will not result in taxable income to the participant. The participant will realize ordinary income at the time of exercise in an amount equal to the amount of cash or the fair market value of the shares paid upon exercise, and the Company will be entitled to a corresponding deduction. Gains or losses realized by the participant upon disposition of any shares received will be treated as capital gains or losses, with the basis in such stock equal to the fair market value of the shares at the time of exercise.

Restricted Stock and Performance-Based Shares. A grant of restricted stock or performance-based shares will not result in taxable income to the participant at the time of grant, and the Company will not be entitled to a corresponding deduction, assuming that the shares are subject to transferability restrictions and that certain restrictions on the shares constitute a “substantial risk of forfeiture” for federal income tax purposes. Upon vesting, the holder will realize ordinary income in an amount equal to the then fair market value of the vested shares, and the Company will be entitled to a corresponding deduction. Gains or losses realized by the participant upon subsequent disposition of such shares will be treated as capital gains or losses, with the basis in such shares equal to the fair market value of the shares at the time of vesting. Dividends paid to the holder of restricted stock during the restricted period also will be compensation income to the participant, and the Company will be entitled to a corresponding deduction when the dividends no longer are subject to a substantial risk of forfeiture or become transferable. A participant may be permitted to elect, pursuant to Section 83(b) of the Internal Revenue Code, to have income recognized at the date a restricted stock award or performance share award, as the case may be, is granted and to have the applicable capital gain holding period commence as of that date. In such a case, the Company would be entitled to a corresponding deduction on the date of grant.

Restricted Stock Units. A grant of restricted stock units (including performance-based restricted stock units) will not result in taxable income to the participant at the time of grant, and the Company will not be entitled to a corresponding deduction. Upon vesting and issuance of the underlying shares, the holder will realize ordinary income in an amount equal to the then fair market value of the issued shares, and the Company will be entitled to a corresponding deduction. Gains or losses realized by the participant upon disposition of such shares will be treated as capital gains or losses, with the basis in such shares equal to the fair market value of the shares at the time of vesting and issuance. Dividend equivalents paid to the holder of restricted stock units during the restricted period also will be compensation income to the participant, and the Company will be entitled to a corresponding deduction when the dividend equivalents are paid.

Performance Awards and Other Share-Based or Cash-Based Awards. A grant of a performance award or other stock-based or cash-based award will not result in taxable income to the participant at the time of grant, and the Company will not be entitled to a corresponding deduction. Upon payment of cash or the vesting or issuance of the underlying shares, the participant will realize ordinary income in an amount equal to the cash received or the

then fair market value of the issued shares, and the Company will be entitled to a corresponding deduction. Gains or losses realized by the participant upon subsequent disposition of such shares will be treated as capital gains or losses, with the basis in such shares equal to the fair market value of the shares at the time of vesting and issuance.

Deductibility Limit on Compensation in Excess of $1 Million. Section 162(m) of the Internal Revenue Code generally limits the deductible amount of total annual compensation paid by a public company to each “covered employee” to no more than $1 million.

Tax Withholding. As a condition to the delivery of any shares to the recipient of an award, the Company may require the recipient to make arrangements for meeting certain tax withholding requirements in connection with the award.

Importance of Consulting Tax Adviser. The information set forth above is a summary only and does not purport to be complete. In addition, the information is based upon current Federal income tax rules and therefore is subject to change when those rules change. Moreover, because the tax consequences to any recipient may depend on his or her particular situation, each recipient should consult his or her tax adviser as to the Federal, state, local, foreign and other tax consequences of the grant or exercise of an award or the disposition of shares acquired as a result of an award.

Vote Required for Approval

PROPOSAL 3

NON-BINDING, ADVISORY VOTE ON THE

COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Background

Section 14A of the Exchange Act, put in place by Section 951 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires the Company to seek a non-binding advisory vote from its stockholders to approve the compensation of its named executive officers (“Say-on-Pay” vote) as disclosed pursuant to Item 402 of Regulation S-K, and accompanying compensation tables and the related narrative disclosure in this Proxy Statement. Because the required vote is advisory, the result of the vote is not binding upon the Board of Directors.

We believe that executive compensation should be linked to the Company’s performance and aligned with the interests of the Company’s stockholders. In addition, executive compensation is designed to allow the Company to recruit, retain and motivate employees who play a significant role in the organization’s current and future success.

The Compensation Committee values the perspectives and concerns of our stockholders regarding executive compensation. The Compensation Committee has in the past and intends to continue to maintain in the future an open dialogue with stockholders to foster greater communication and transparency on our executive compensation programs.

Proposal

The Company is presenting this proposal, which gives you as a stockholder the opportunity to express your view on the compensation of our named executive officers by voting for or against the following resolution:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation tables and other narrative executive compensation disclosures contained in the Company’s proxy statement for the 2021 annual meeting, is hereby APPROVED.”

Position of Board of Directors

As discussed in this proxy statement under the “Compensation of Officers and Directors” Section, the Compensation Committee of the Board of Directors believes that the executive compensation for the year ended December 31, 2020, is reasonable and appropriate, is justified by the performance of the Company and is the result of a carefully considered approach after taking into account feedback from our stockholders. Our executive compensation program is designed to attract, motivate and retain a highly qualified group of executives and maintain a close correlation between the rewards to the Company’s executives and the strategic success of the Company and the performance of its stock.

Effect of Vote

Because your vote is advisory, it will not be binding upon the Company, the Compensation Committee or the Board of Directors; however, we value stockholders’ opinions, and we will consider the outcome of the Say-on-Pay vote when determining future executive compensation arrangements.

Vote Required for Approval

A majority of the votes cast is required to approve this resolution. Even though this vote will neither be binding on the Company or the Board of Directors nor will it create or imply any change in the fiduciary duties of, or impose any additional fiduciary duty on, the Company or the Board of Directors, the Compensation Committee will take into account the outcome of the vote when considering future executive compensation decisions. Abstentions and broker non-votes will have no effect on the outcome of this proposal.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RESOLUTION TO APPROVE THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

PROPOSAL 4

RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed Crowe LLP (“Crowe”) to continue in its capacity as our independent registered public accounting firm for the fiscal year ending December 31, 2021, and the Board has directed that management submit the appointment of the independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Crowe has audited our financial statements for the years ended December 31, 2020 and 2019.

Neither our bylaws nor other governing documents or law require stockholder ratification of the appointment of Crowe as our independent registered public accounting firm. However, the Board is submitting the appointment of Crowe to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to continue to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

A majority of the votes cast at the Annual Meeting will be required to ratify the appointment of Crowe. Abstentions will not have any effect on the outcome of this proposal.

Representatives of Crowe are expected to be present at the Annual Meeting via telephone. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF CROWE AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2021.

AUDIT-RELATED MATTERS

Report of the Audit Committee

The Audit Committee represents and assists the Board by overseeing: (i) the Company's financial statements and internal controls; (ii) the independent registered public accounting firm's qualifications and independence; and (iii) the performance of the Company's independent registered public accounting firm.

On the date of the adoption of this Report, the Audit Committee consisted of three directors, all considered independent in accordance with Nasdaq listing standards and other applicable regulations. Each member of the Audit Committee is financially literate and our Board has determined that committee member, Ms. Krzeminski, is an “audit committee financial expert” as defined in applicable SEC rules because she meets the requirement for past employment experience in finance or accounting, requisite professional certification in accounting or comparable experience.

Company management has the primary responsibility for the preparation of the financial statements and for the reporting process, including the establishment and maintenance of the Company's system of internal controls over financial reporting. The Company's independent registered public accounting firm is responsible for auditing the financial statements prepared by management and expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles.

In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with both management and the independent registered public accounting firm, the Company's quarterly earnings releases, Quarterly Reports on Form 10-Q, and the 2020 Annual Report on Form 10-K. Such reviews included a discussion of critical or significant accounting policies, the reasonableness of significant judgments, the quality (not just the acceptability) of the accounting principles, the reasonableness and clarity of the financial statement disclosures, and such other matters as the independent registered public accounting firm is required to review with the Audit Committee under the standards promulgated by the Public Company Accounting Oversight Board. The Audit Committee also discussed with both management and the Company's independent registered public accounting firm the design and efficacy of the Company's internal control over financial reporting.

The Audit Committee has also discussed with the independent registered public accounting firm the matters required to be discussed by Auditing Standard No. 1301, “Communications with Audit Committees” issued by the Public Company Accounting Oversight Board (“PCAOB”). The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB (regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence), and considered the compatibility of non-audit services rendered to Limbach with the independence of the Company's independent registered public accounting firm. The Audit Committee has determined that the rendering of the services other than audit services by Crowe is compatible with maintaining the principal accountant’s independence.

The Audit Committee also discussed with the independent registered public accounting firm the overall scope and plans for its audit. The Audit Committee periodically met with the independent registered public accounting firm, with and without management present, to discuss the results of their work and the overall quality of Limbach’s financial reporting.

In reliance on these reviews and discussions, the Audit Committee recommended to the Board that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2020 for filing with the SEC.


						Respectfully submitted,

						AUDIT COMMITTEE
						Laurel J. Krzeminski
						Joshua S. Horowitz
						Michael F. McNally

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

Independent Registered Public Accounting Firm Fees

The aggregate fees billed by Limbach’s principal accounting firm, Crowe LLP, for auditing the annual financial statements and related regulations included in the Annual Report on Form 10-K, the reviews of the quarterly financial statements included in the Quarterly Reports on Form 10-Q, assistance with and review of documents filed with the SEC, and consultations on certain accounting and reporting matters for each of the last two fiscal years are set forth as “Audit Fees” in the table below.

Also set forth for the last two fiscal years are “Audit-Related Fees.” Such fees pertain to professional services for assurance and related services that are reasonably related to the performance of the audit of our financial statements and are not reported under “Audit fees.” These services include services and consultations related to the Company’s material weaknesses in internal control, the Company’s IT controls, financial accounting and reporting standards.

“Tax Fees” include fees for tax advice and tax planning. “All Other Fees” consisted of permitted services other than those that meet the criteria described above. Crowe LLP did not provide any services to the Company related to financial information systems design or implementation, nor did it provide any personal tax work or other services for any of the Company's executive officers or members of the Board.

The following table shows the fees for professional services rendered to us by Crowe for services in respect of the years ended December 31, 2020 and 2019.


	2020		2019
Audit Fees	$	601,232	$	758,725
Audit-Related Fees	15,000		19,905
Tax Fees	—		—
All Other Fees	—		—
Total Fees	$	616,232	$	778,630

Consistent with the Audit Committee charter, audit, audit-related, tax, and other services are pre-approved by the Audit Committee, or by a designated member thereof. The Audit Committee has determined that the provision of the non-audit services described above is compatible with maintaining Crowe’s independence.

RELATED PERSON POLICY AND TRANSACTIONS

Related Person Transactions Policy and Procedures

Our Board has adopted a written related person transaction policy that sets forth the policies and procedures for the review and approval or ratification of related person transactions. This policy is administered by our Nominating and Corporate Governance Committee and covers any transaction, arrangement, or relationship, or any series of similar transactions, arrangements, or relationships, in which the Company was or is to be a participant, the amount involved exceeds $100,000 and in which a related person had or will have a direct or indirect material interest. While the policy covers related person transactions in which the amount involved exceeds $100,000, the policy states that related person transactions in which the amount involved exceed $120,000 are required to be disclosed in applicable filings as required by the Securities Act, Exchange Act, and related rules. Our Board set the threshold for approval of related person transactions in the policy at an amount lower than that which is required to be disclosed under the Securities Act, Exchange Act, and related rules because we believe that it is appropriate for the Nominating and Corporate Governance Committee to review transactions or potential transactions in which the amount involved exceeds $100,000, as opposed to $120,000. Pursuant to this policy, our Nominating and Corporate Governance Committee, among other things, (i) reviews the relevant facts and circumstances of each related person transaction, including if the transaction is on terms comparable to those that could be obtained in arm’s-length dealings with an unrelated third party and the extent of the related party’s interest in the transaction, and (ii) takes into account the conflicts of interest and corporate opportunity provisions of our code of business conduct and ethics. Management presents to our Nominating and Corporate Governance Committee each proposed related person transaction, including all relevant facts and circumstances relating thereto, and updates the Nominating and Corporate Governance Committee as to any material changes to any related person transaction. All related person transactions may only be consummated if our Nominating and Corporate Governance Committee has approved or ratified such transaction in accordance with the guidelines set forth in the policy. Certain types of transactions are excluded by our Nominating and Corporate Governance Committee under the policy. These excluded transactions include: (i) certain compensation arrangements; (ii) transactions in the ordinary course of business where the related party’s interest arises only (a) from his or her position as a director of another entity that is party to the transaction, (b) from an equity interest of less than 5% in another entity that is party to the transaction, or (c) from a limited partnership interest of less than 5% subject to certain limitations; and (iii) transactions in the ordinary course of business where the interest of the related party arises solely from the ownership of a class of our equity securities where all holders of such class of equity securities will receive the same benefit on a pro rata basis. No director will be permitted to participate in the approval of a related person transaction for which he or she is a related party.

Related Person Transactions

Other than the existing Registration Rights Agreement as described below, during 2020 and 2019, the Company did not enter into any related person transactions.

Registration Rights Agreement

In connection with the closing of the Business Combination, we entered into an amended and restated registration rights agreement, dated July 20, 2016, by and among the Company, 1347 Investors and EarlyBirdCapital, Inc., as amended on October 11, 2016 and as further amended on November 23, 2016, whereby we agreed to register the offer and sale from time to time, separately or together, of shares of our common stock issued pursuant to the Business Combination, shares of our common stock underlying the warrants and Preferred Stock issued in connection with the Business Combination, share of our common stock issued in a private placement prior to and concurrently with our initial public offering, and share of our common stock underlying the Sponsor Warrants and $15 Exercise Price Warrants. The holders of these securities also have certain “piggy-back” registration rights with respect to registration statements we file, subject to certain limitations. In connection with these obligations, we filed registration statements on Form S-3 (File Nos. 333-218480, 333-220265 and 333-232406), which have been declared effective. We are required under the terms of the amended and restate registration rights agreement to use our reasonable best efforts to keep these resale registration statements effective under the Securities Act at all times and to take all such other actions as are reasonably necessary to ensure that there is an effective “shelf” registration statement containing a prospectus that remains current covering (and to qualify under required U.S. state securities laws, if any) the offer and sale of all Registrable Securities (as defined in the amended and restated registration rights agreement) by the holders thereof on a continuous basis pursuant to Rule 415 of the Securities Act.

OTHER MATTERS

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g. brokers) to satisfy the delivery requirements for annual meeting materials with respect to two or more stockholders sharing the same address by delivering a single set of annual meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and costs savings for companies.

This year, a number of brokers with account holders who are our stockholders will be “householding” our proxy materials. A single set of Annual Meeting materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of annual meeting materials, please notify your broker or us. Direct your written request to our General Counsel at 1251 Waterfront Place, Suite 102, Pittsburgh, Pennsylvania 15222. Stockholders who currently receive multiple copies of the annual meeting materials at their address and would like to request “householding” of their communications should contact their brokers.

Electronic Access to Proxy Statement and Annual Report

This Proxy Statement and the Annual Report are available on the Company’s website at www.limbachinc.com under “Investor Relations - Financial Information.” Instead of receiving paper copies of the Annual Report and Proxy Statement in the mail, stockholders can elect to receive an e-mail that will provide an electronic link to these documents. Choosing to receive your proxy materials online will save us the cost of producing and mailing documents to your home or business, and also will give you an electronic link to the proxy voting site.

Stockholders of Record. Stockholders of record can choose to receive materials electronically by following the instructions provided if voting over the Internet.

If you choose to receive future proxy statements and annual reports over the Internet, you will receive an e-mail next year with instructions containing the Internet address of those materials and the electronic link to the proxy voting site. The election will remain in effect until you write or call the Company’s Investor Relations Department and tell us otherwise.

Beneficial Owners. If you hold your shares in a brokerage account, you may also have the ability to receive copies of the Annual Report and Proxy Statement electronically. Please check the information provided in the proxy materials sent to you by your bank, broker or other holder of record regarding the availability of electronic delivery.

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his/her best judgment.

(vv) “Substitute Award” shall mean an Award granted under the Plan upon the assumption of, or in substitution for, outstanding equity awards granted by a company or other entity in connection with a corporate transaction, such as a merger, combination, consolidation, or acquisition of property or stock; provided, however, that in no event shall the term “Substitute Award” be construed to refer to an award made in connection with the cancellation and repricing of an Option or Stock Appreciation Right.

Section 3. Administration.

(a) The Plan shall be administered by the Administrator in accordance with the requirements of Rule 16b-3 under the Exchange Act (“Rule 16b-3”), to the extent applicable.

(b) Pursuant to the terms of the Plan, the Administrator, subject, in the case of any Committee, to any restrictions on the authority delegated to it by the Board, shall have the power and authority, without limitation:

(i) to select those Eligible Recipients who shall be Participants;

(ii) to determine whether and to what extent Options, Stock Appreciation Rights, Restricted Shares, Restricted Stock Units, Other Share Based Awards, Other Cash-Based Awards or a combination of any of the foregoing, are to be granted hereunder to Participants;

(iii) to determine the number of Shares to be covered by each Award granted hereunder;

(iv) to determine the terms and conditions, not inconsistent with the terms of the Plan, of each Award granted hereunder, including, but not limited to, (A) the restrictions applicable to Restricted Shares and Restricted Stock Units and the conditions under which restrictions applicable to such Restricted Shares and Restricted Stock Units shall lapse, (B) the Performance Goals and periods applicable to Awards, if any, (C) the Exercise Price of each Award, (D) the vesting schedule applicable to each Award, (E) the number of Shares subject to each Award and (F) subject to the requirements of Code Section 409A (to the extent applicable), any amendments to the terms and conditions of outstanding Awards, including, but not limited to, extending the exercise period of such Awards and accelerating the vesting schedule of such Awards;

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, which shall govern all written instruments evidencing Options, Stock Appreciation Rights, Restricted Shares, Restricted Stock Units or Other Share Based Awards, Other Cash-Based Awards or any combination of the foregoing granted hereunder;

(vi) to determine the Fair Market Value;

(vii) to determine the duration and purpose of leaves of absence which may be granted to a Participant without constituting termination of the Participant’s employment for purposes of Awards granted under the Plan;

(viii) to adopt, alter and repeal such administrative rules, guidelines and practices governing the Plan as it shall from time to time deem advisable; and

(ix) to construe and interpret the terms and provisions of the Plan and any Award issued under the Plan (and any Award Agreement relating thereto), and to otherwise supervise the administration of the Plan and to exercise all powers and authorities either specifically granted under the Plan or necessary and advisable in the administration of the Plan.

(c) All decisions made by the Administrator pursuant to the provisions of the Plan shall be final, conclusive and binding on all persons, including the Company and the Participants. No member of the Board or the Committee, or any officer or employee of the Company or any Subsidiary thereof acting on behalf of the Board or the Committee, shall be personally liable for any action, omission, determination, or interpretation taken or made in good faith with respect to the Plan, and all members of the Board or the Committee and each and any officer or employee of the Company and of any Subsidiary thereof acting on their behalf shall, to the maximum extent permitted by law, be fully indemnified and protected by the Company in respect of any such action, omission, determination or interpretation.

Section 4. Shares Reserved for Issuance Under the Plan and Limitations on Awards.

(a) Subject to Section 5 of the Plan, the number of Shares that are reserved and available for issuance pursuant to Awards granted under the Plan is 2,250,000. The maximum number of Shares that may be issued pursuant to Options intended to be Incentive Stock Options is eight-hundred thousand (800,000).

(b) The aggregate Awards granted during any fiscal year to any Participant shall not exceed, subject to adjustment as provided in Section 5 of the Plan: (i) is four-hundred thousand (400,000) Shares subject to Options or Stock Appreciation Rights, (ii) is four-hundred thousand (400,000) Shares subject to Restricted Shares, Restricted Stock Units or Other Share Based Awards (other than Stock Appreciation Rights), and (iii) two million dollars ($2,000,000) with respect to Other Cash-Based Awards with a Restricted Period of one (1) year and five-hundred thousand dollars ($500,000) with respect to Other Cash-Based Awards with a Restricted Period greater than one (1) year. Notwithstanding the foregoing, the maximum number of Shares subject to Awards granted during any fiscal year to any non-employee Director, taken together with any cash fees paid to such non-employee Director during the fiscal year, shall not exceed five-hundred thousand dollars ($500,000) in total value (calculating the value of any such Awards based on the grant date Fair Market Value of such Awards for financial reporting purposes).

(c) Shares issued under the Plan may, in whole or in part, be authorized but unissued Shares or Shares that shall have been or may be reacquired by the Company in the open market, in private transactions or otherwise. Any Shares subject to an Award under the Plan that, after the Effective Date, are forfeited, canceled, settled or otherwise terminated without a distribution of Shares to a Participant will thereafter be deemed to be available for Awards. In applying the immediately preceding sentence, if (i) Shares otherwise issuable or issued in respect of, or as part of, any Award are withheld to cover taxes or any applicable Exercise Price, such Shares shall be treated as having been issued under the Plan and shall not be available for issuance under the Plan, and (ii) any Share-settled Stock Appreciation Rights or Options are exercised, the aggregate number of Shares subject to such Stock Appreciation Rights or Options shall be deemed issued under the Plan and shall not be available for issuance under the Plan. In addition, Shares tendered to exercise outstanding Options or other Awards or to cover applicable taxes on any Awards shall not be available for issuance under the Plan.

(d) Except in the case of Substitute Awards granted pursuant to Section 4(e) and subject to the following sentence, Awards granted under the Plan shall be subject to a minimum vesting period of one (1) year. Notwithstanding the foregoing, (i) the Committee may provide that the vesting of an Award shall accelerate in the event of the Participant’s death, Disability, or Retirement, or the occurrence of a Change in Control, and (ii) the Committee may grant Awards covering five percent (5%) or fewer of the total number of Shares authorized under the Plan without respect to the above-described minimum vesting requirement. Notwithstanding the foregoing, with respect to Awards to non-employee Directors, the vesting of such Awards will be deemed to satisfy the one (1) year minimum vesting requirement to the extent that the Awards vest on the earlier of the one (1) year anniversary of the date of grant and the next annual meeting of the Company’s stockholders that is at least fifty (50) weeks after the immediately preceding year’s annual meeting.

(e) Substitute Awards shall not reduce the Shares authorized for grant under the Plan. In the event that a company acquired by the Company or any Affiliate or with which the Company or any Affiliate combines has shares available under a pre-existing plan approved by stockholders 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 not reduce the Shares authorized for grant under the Plan; provided, that 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 employed by or providing services to the Company or its Affiliates immediately prior to such acquisition or combination.

(f) In the event that the Company or an Affiliate thereof consummates a transaction described in Code Section 424(a) (e.g., the acquisition of property or stock from an unrelated corporation), persons who become Employees or Directors in account of such transaction may be granted Substitute Awards in substitution for awards granted by their former employer, and any such substitute Options or Stock Appreciation Rights may be granted with an Exercise Price less than the Fair Market Value of a Share on the grant date thereof; provided, however, the grant of such substitute Option or Stock Appreciation Right shall not constitute a “modification” as defined in Code Section 424(h)(3) and the applicable Treasury regulations.

Section 5. Equitable Adjustments.

In the event of any Change in Capitalization, an equitable substitution or proportionate adjustment shall be made, in each case, as may be determined by the Administrator, in its sole discretion, in (i) the aggregate number of Shares reserved for issuance under the Plan and the maximum number of Shares that may be subject to Awards granted to any Participant in any calendar or fiscal year, (ii) the kind, number and Exercise Price subject to outstanding Options and Stock Appreciation Rights granted under the Plan; provided, however, that any such substitution or adjustment with respect to Options and Stock Appreciation Rights shall occur in accordance with the requirements of Code Section 409A, and (iii) the kind, number and purchase price of Shares subject to outstanding Restricted Shares or Other Share Based Awards granted under the Plan, in each case as may be determined by the Administrator, in its sole discretion; provided, however, that any fractional Shares resulting from the adjustment shall be eliminated. Such other equitable substitutions or adjustments shall be made as may be determined by the Administrator, in its sole discretion. Without limiting the generality of the foregoing, in connection with a Change in Capitalization, the Administrator may provide, in its sole discretion, for the cancellation of any outstanding Award granted hereunder in exchange for payment in cash or other property having an aggregate Fair Market Value of the Shares covered by such Award, reduced by the aggregate Exercise Price or purchase price thereof, if any. Notwithstanding anything contained in the Plan to the contrary, any adjustment with respect to an Incentive Stock Option due to an adjustment or substitution described in this Section 5 shall comply with the rules of Code Section 424(a), and in no event shall any adjustment be made which would render any Incentive Stock Option granted hereunder to be disqualified as an incentive stock option for purposes of Code Section 422. The Administrator’s determinations pursuant to this Section 5 shall be final, binding and conclusive.

Section 6. Eligibility.

The Participants under the Plan shall be selected from time to time by the Administrator, in its sole discretion, from among Eligible Recipients.

Section 7. Options.

(a) General. The Committee may, in its sole discretion, grant Options to Participants. Solely with respect to Participants who are Employees, the Committee may grant Incentive Stock Options, Nonqualified Stock Options or a combination of both. With respect to all other Participants, the Committee may grant only Nonqualified Stock Options. Each Participant who is granted an Option shall enter into an Award Agreement with the Company, containing such terms and conditions as the Administrator shall determine, in its sole discretion, which Award Agreement shall specify whether the Option is an Incentive Stock Option or a Nonqualified Stock Option and shall set forth, among other things, the Exercise Price of the Option, the term of the Option and provisions regarding exercisability of the Option granted thereunder. The provisions of each Option need not be the same with respect to each Participant. More than one Option may be granted to the same Participant and be outstanding concurrently hereunder. Options granted under the Plan shall be subject to the terms and conditions set forth in this Section 7 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable and set forth in the applicable Award Agreement. The prospective recipient of an Option shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(b) Limits on Incentive Stock Options. If the Administrator grants Incentive Stock Options, then to the extent that the aggregate fair market value of Shares with respect to which Incentive Stock Options are exercisable for the first time by any individual during any calendar year (under all plans of the Company) exceeds $100,000, such Options will be treated as Nonqualified Stock Options to the extent required by Code Section 422.

(c) Exercise Price. The Exercise Price of Shares purchasable under an Option shall be determined by the Administrator in its sole discretion at the time of grant; provided, however, that (i) in no event shall the Exercise Price of an Option be less than one hundred percent (100%) of the Fair Market Value of the Common Stock on the date of grant, and (ii) no Incentive Stock Option granted to a ten percent (10%) stockholder of the Company’s Common Stock (within the meaning of Code Section 422(b)(6)) shall have an exercise price per share less than one-hundred ten percent (110%) of the Fair Market Value of a Share on such date.

(d) Option Term. The maximum term of each Option shall be fixed by the Administrator, but in no event shall (i) an Option be exercisable more than ten (10) years after the date such Option is granted, and (ii) an Incentive Stock Option granted to a ten percent (10%) stockholder of the Company’s Common Stock (within the meaning of

Code Section 422(b)(6)) be exercisable more than five (5) years after the date such Option is granted. Each Option’s term is subject to earlier expiration pursuant to the applicable provisions in the Plan and the Award Agreement. Notwithstanding the foregoing, the Administrator shall have the authority to accelerate the exercisability of any outstanding Option at such time and under such circumstances as the Administrator, in its sole discretion, deems appropriate. Notwithstanding any contrary provision in this Plan (including without limitation Section 7(h)), if, on the date an outstanding Option would expire, the exercise of the Option, including by a “net exercise” or “cashless” exercise, would violate applicable securities laws or any insider trading policy maintained by the Company from time to time, the expiration date applicable to the Option will be extended, except to the extent such extension would violate Section 409A, to a date that is thirty (30) calendar days after the date the exercise of the Option would no longer violate applicable securities laws or any such insider trading policy.

(e) Exercisability. Each Option shall be exercisable at such time or times and subject to such terms and conditions, including the attainment of pre-established Performance Goals, as shall be determined by the Administrator in the applicable Award Agreement. The Administrator may also provide that any Option shall be exercisable only in installments, and the Administrator may waive such installment exercise provisions at any time, in whole or in part, based on such factors as the Administrator may determine in its sole discretion. Notwithstanding anything to the contrary contained herein, an Option may not be exercised for a fraction of a share.

(f) Method of Exercise. Options may be exercised in whole or in part by giving written notice of exercise to the Company specifying the number of Shares to be purchased, accompanied by payment in full of the aggregate Exercise Price of the Shares so purchased in cash or its equivalent, as determined by the Administrator. As determined by the Administrator, in its sole discretion, with respect to any Option or category of Options, payment in whole or in part may also be made (i) by means of consideration received under any cashless exercise procedure approved by the Administrator (including the withholding of Shares otherwise issuable upon exercise), (ii) in the form of unrestricted Shares already owned by the Participant which have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Shares as to which such Option shall be exercised, (iii) any other form of consideration approved by the Administrator and permitted by applicable law or (iv) any combination of the foregoing. In determining which methods a Participant may utilize to pay the Exercise Price, the Administrator may consider such factors as it determines are appropriate; provided, however, that with respect to Incentive Stock Options, all such discretionary determinations shall be made by the Administrator at the time of grant and specified in the Award Agreement.

(g) Rights as Stockholder. A Participant shall have no rights to dividends or any other rights of a stockholder with respect to the Shares subject to an Option until the Participant has given written notice of the exercise thereof, has paid in full for such Shares and has satisfied the requirements of Section 15 of the Plan.

(h) Termination of Employment or Service.

(i) Unless the applicable Award Agreement provides otherwise, in the event that the employment or service of a Participant with the Company and all Affiliates thereof shall terminate for any reason other than Cause, Retirement, Disability, or death, (A) Options granted to such Participant, to the extent that they are exercisable at the time of such termination, shall remain exercisable until the date that is ninety (90) days after such termination, on which date they shall expire, and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. The ninety (90) day period described in this Section 7(h)(i) shall be extended to one (1) year after the date of such termination in the event of the Participant’s death during such ninety (90) day period. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(ii) Unless the applicable Award Agreement provides otherwise, in the event that the employment or service of a Participant with the Company and all Affiliates thereof shall terminate on account of Retirement, Disability or the death of the Participant, (A) Options granted to such Participant, to the extent that they were exercisable at the time of such termination, shall remain exercisable until the date that is one (1) year after such termination, on which date they shall expire and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(iii) In the event of the termination of a Participant’s employment or service for Cause, all outstanding Options granted to such Participant shall expire at the commencement of business on the date of such termination.

(iv) For purposes of determining which Options are exercisable upon termination of employment or service for purposes of this Section 7(h), Options that are not exercisable solely due to a blackout period shall be considered exercisable.

(i) Other Change in Employment Status. An Option may be affected, both with regard to vesting schedule and termination, by leaves of absence, changes from full-time to part-time employment, partial disability or other changes in the employment status or service of a Participant, as evidenced in a Participant’s Award Agreement.

(j) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Options shall be subject to Section 12 of the Plan.

(k) Automatic Exercise. Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable Option outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. In the sole discretion of the Administrator, payment of the exercise price of any such Option shall be made pursuant to Section 7(f)(i), or (ii) and the Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 15. Unless otherwise determined by the Administrator, this Section 7(k) shall not apply to an Option if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Option with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 7(k).

Section 8. Stock Appreciation Rights.

(a) General. Stock Appreciation Rights may be granted either alone (“Free Standing Rights”) or in conjunction with all or part of any Option granted under the Plan (“Related Rights”). Related Rights may be granted either at or after the time of the grant of such Option. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Stock Appreciation Rights shall be made, the number of Shares to be awarded, the price per Share, and all other conditions of Stock Appreciation Rights. Notwithstanding the foregoing, no Related Right may be granted for more Shares than are subject to the Option to which it relates and any Stock Appreciation Right must be granted with an Exercise Price not less than the Fair Market Value of Common Stock on the date of grant. The provisions of Stock Appreciation Rights need not be the same with respect to each Participant. Stock Appreciation Rights granted under the Plan shall be subject to the following terms and conditions set forth in this Section 8 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable, as set forth in the applicable Award Agreement.

(b) Awards; Rights as Stockholder. The prospective recipient of a Stock Appreciation Right shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Participants who are granted Stock Appreciation Rights shall have no rights as stockholders of the Company with respect to the grant or exercise of such rights.

(i) Stock Appreciation Rights that are Free Standing Rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii) Stock Appreciation Rights that are Related Rights shall be exercisable only at such time or times and to the extent that the Options to which they relate shall be exercisable in accordance with the provisions of Section 7 above and this Section 8 of the Plan.

(d) Payment Upon Exercise.

(i) Upon the exercise of a Free Standing Right, the Participant shall be entitled to receive up to, but not more than, that number of Shares, determined using the Fair Market Value, equal in value to the excess of the Fair Market Value as of the date of exercise over the price per share specified in the Free Standing Right multiplied by the number of Shares in respect of which the Free Standing Right is being exercised.

(ii) A Related Right may be exercised by a Participant by surrendering the applicable portion of the related Option. Upon such exercise and surrender, the Participant shall be entitled to receive up to, but not more than, that number of Shares, determined using the Fair Market Value, equal in value to the excess of the Fair Market Value as of the date of exercise over the Exercise Price specified in the related Option multiplied by the number of Shares in respect of which the Related Right is being exercised. Options which have been so surrendered, in whole or in part, shall no longer be exercisable to the extent the Related Rights have been so exercised.

(iii) Notwithstanding the foregoing, the Administrator may determine to settle the exercise of a Stock Appreciation Right in cash (or in any combination of Shares and cash).

(e) Termination of Employment or Service.

(i) Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Free Standing Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii) Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Related Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as set forth in the related Options.

(f) Term.

(i) The term of each Free Standing Right shall be fixed by the Administrator, but no Free Standing Right shall be exercisable more than ten (10) years after the date such right is granted.

(ii) The term of each Related Right shall be the term of the Option to which it relates, but no Related Right shall be exercisable more than ten (10) years after the date such right is granted.

(g) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Stock Appreciation Rights shall be subject to Section 12 of the Plan.

(h) Automatic Exercise. Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable Stock Appreciation Right outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. The Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 15. Unless otherwise determined by the Administrator, this Section 8(h) shall not apply to a Stock Appreciation Right if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Stock Appreciation Right with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 8(h).

Section 9. Restricted Shares.

(a) General. Restricted Shares may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Restricted Shares shall be made; the number of Shares to be awarded; the price, if any, to be paid by the Participant for the acquisition of Restricted Shares; the Restricted Period, if any, applicable to Restricted Shares; the Performance Goals (if any) applicable to Restricted Shares; and all other conditions of the Restricted Shares. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Shares in accordance with the terms of the grant. The provisions of the Restricted Shares need not be the same with respect to each Participant.

(b) Awards and Certificates. The prospective recipient of Restricted Shares shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Except as otherwise provided in Section 9(c) of the Plan, (i) each Participant who is granted an award of Restricted Shares may, in the Company’s sole discretion, be issued a stock certificate in respect of such Restricted Shares; and (ii) any such certificate so issued shall be registered in the name of the Participant, and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to any such Award.

The Company may require that the stock certificates, if any, evidencing Restricted Shares granted hereunder be held in the custody of the Company until the restrictions thereon shall have lapsed, and that, as a condition of any award of Restricted Shares, the Participant shall have delivered a stock power, endorsed in blank, relating to the Shares covered by such Award.

Notwithstanding anything in the Plan to the contrary, any Restricted Shares (whether before or after any vesting conditions have been satisfied) may, in the Company’s sole discretion, be issued in uncertificated form pursuant to the customary arrangements for issuing shares in such form.

(c) Restrictions and Conditions. The Restricted Shares granted pursuant to this Section 9 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or thereafter:

(i) The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain Performance Goals, the Participant’s termination of employment or service as a non-employee Director or Consultant of the Company or an Affiliate thereof, or the Participant’s death or Disability.

(ii) Except as provided in Section 17 of the Plan or in the Award Agreement, the Participant shall generally have the rights of a stockholder of the Company with respect to Restricted Shares during the Restricted Period. In the Administrator’s discretion and as provided in the applicable Award Agreement, a Participant may be entitled to dividends or dividend equivalents on an Award of Restricted Shares, which will be payable in accordance with the

terms of such grant as determined by the Administrator. Certificates for Shares of unrestricted Common Stock may, in the Company’s sole discretion, be delivered to the Participant only after the Restricted Period has expired without forfeiture in respect of such Restricted Shares, except as the Administrator, in its sole discretion, shall otherwise determine.

(iii) The rights of Participants granted Restricted Shares upon termination of employment or service as a non-employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Shares shall be subject to Section 12 of the Plan.

Section 10. Restricted Stock Units.

(a) General. Restricted Stock Units may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Restricted Stock Units shall be made; the number of Restricted Stock Units to be awarded; the Restricted Period, if any, applicable to Restricted Stock Units; the Performance Goals (if any) applicable to Restricted Stock Units; and all other conditions of the Restricted Stock Units. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Stock Units in accordance with the terms of the grant. The provisions of Restricted Stock Units need not be the same with respect to each Participant.

(b) Award Agreement. The prospective recipient of Restricted Stock Units shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c) Restrictions and Conditions. The Restricted Stock Units granted pursuant to this Section 10 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or, subject to Code Section 409A, thereafter:

(ii) Participants holding Restricted Stock Units shall have no voting rights. A Restricted Stock Unit may, at the Administrator’s discretion, carry with it a right to dividend equivalents. Such right would entitle the holder to be credited with an amount equal to all cash dividends paid on one Share while the Restricted Stock Unit is outstanding. The Administrator, in its discretion, may grant dividend equivalents from the date of grant or only after a Restricted Stock Unit is vested.

(iii) The rights of Participants granted Restricted Stock Units upon termination of employment or service as a non-employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d) Settlement of Restricted Stock Units. Settlement of vested Restricted Stock Units shall be made to Participants in the form of Shares, unless the Administrator, in its sole discretion, provides for the payment of the Restricted Stock Units in cash (or partly in cash and partly in Shares) equal to the value of the Shares that would otherwise be distributed to the Participant.

(e) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Stock Units shall be subject to Section 12 of the Plan.

Section 11. Other Share Based or Cash-Based Awards.

(a) The Administrator is authorized to grant Awards to Participants in the form of Other Share Based Awards or Other Cash-Based Awards, as deemed by the Administrator to be consistent with the purposes of the Plan and as evidenced by an Award Agreement. The Administrator shall determine the terms and conditions of such Awards, consistent with the terms of the Plan, at the date of grant or thereafter, including any Performance Goals and performance periods. Common Stock or other securities or property delivered pursuant to an Award in the nature of a purchase right granted under this Section 11 shall be purchased for such consideration, paid for at such times, by such methods, and in such forms, including, without limitation, Shares, other Awards, notes or other property, as the Administrator shall determine, subject to any required corporate action.

(b) The prospective recipient of an Other Share-Based Award or Other Cash-Based Award shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c) Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Other Share-Based Awards and Other Cash-Based Awards shall be subject to Section 12 of the Plan.

Section 12. Change in Control.

The Administrator may provide in the applicable Award Agreement that an Award will vest on an accelerated basis upon the Participant’s termination of employment or service in connection with a Change in Control or upon the occurrence of any other event that the Administrator may set forth in the Award Agreement. If the Company is a party to an agreement that is reasonably likely to result in a Change in Control, such agreement may provide for: (i) the continuation of any Options and Stock Appreciation Rights by the Company, if the Company is the surviving corporation; (ii) the assumption of any Options and Stock Appreciation Rights by the surviving corporation or its parent or subsidiary; (iii) the substitution by the surviving corporation or its parent or subsidiary of equivalent awards for any Options and Stock Appreciation Rights, provided, however, that any such assumption or substitution with respect to Options and Stock Appreciation Rights under the foregoing clauses (ii) or (iii) shall occur in accordance with the requirements of Code Section 409A and 424, when applicable; or (iv) settlement of any Options and Stock Appreciation Rights for the Change in Control Price (less, to the extent applicable, the per share exercise or grant price), or, if the per share exercise or grant price equals or exceeds the Change in Control Price or if the Administrator determines that Award cannot reasonably become vested pursuant to its terms, such Options and Stock Appreciation Rights shall terminate and be canceled. To the extent that Restricted Shares, Restricted Stock Units or other Awards (other than Options and Stock Appreciation Rights) settle in Shares in accordance with their terms upon a Change in Control, such Shares shall be entitled to receive as a result of the Change in Control transaction the same consideration as the Shares held by stockholders of the Company as a result of the Change in Control transaction. For purposes of this Section 12, “Change in Control Price” shall mean the Fair Market Value of a Share upon a Change in Control. To the extent that the consideration paid in any such Change in Control transaction consists all or in part of securities or other non-cash consideration, the value of such securities or other non-cash consideration shall be determined in good faith by the Administrator.

Section 13. Amendment and Termination.

(a) The Board or the Committee may amend, alter or terminate the Plan, but no amendment, alteration, or termination shall be made that would impair the rights of a Participant under any Award theretofore granted without such Participant’s consent.

(b) Notwithstanding the foregoing, (i) approval of the Company’s stockholders shall be obtained to increase the aggregate Share limit and annual Award limits described in Section 4 and for any amendment that would require such approval in order to satisfy the requirements of Code Section 422, if applicable, any rules of the stock exchange on which the Common Stock is traded or other applicable law, and (ii) without stockholder approval to the extent required by the rules of any applicable national securities exchange or inter-dealer quotation system on which the Shares are listed or quoted, except as otherwise permitted under Section 5 of the Plan, (A) no amendment or modification may reduce the Exercise Price of any Option or Stock Appreciation Right, (B) the Committee may not cancel any outstanding Option or Stock Appreciation Right and replace it with a new Option or Stock Appreciation Right, another Award or cash and (C) the Committee may not take any other action that is considered a “repricing” for purposes of the stockholder approval rules of the applicable securities exchange or inter-dealer quotation system.

(c) Subject to the terms and conditions of the Plan and Code Section 409A, the Administrator may modify, extend or renew outstanding Awards under the Plan, or accept the surrender of outstanding Awards (to the extent not already exercised) and grant new Awards in substitution of them (to the extent not already exercised).

(d) Notwithstanding the foregoing, no alteration, modification or termination of an Award will, without the prior written consent of the Participant, adversely alter or impair any rights or obligations under any Award already granted under the Plan.

Section 14. Unfunded Status of Plan.

The Plan is intended to constitute an “unfunded” plan for incentive compensation. With respect to any payments not yet made or Shares not yet transferred to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company.

Section 15. Withholding Taxes.

Each Participant shall, no later than the date as of which the value of an Award first becomes includible in the gross income of such Participant for federal, state and/or local income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any federal, state, or local taxes of any kind, domestic or foreign, required by law or regulation to be withheld with respect to the Award. The obligations of the Company under the Plan shall be conditional on the making of such payments or arrangements, and the Company shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Participant. Whenever cash is to be paid pursuant to an Award granted hereunder, the Company shall have the right to deduct therefrom an amount sufficient to satisfy any federal, state and local withholding tax requirements related thereto. Whenever Shares are to be delivered pursuant to an Award, the Company shall have the right to require the Participant to remit to the Company in cash an amount sufficient to satisfy any related federal, state and local taxes, domestic or foreign, to be withheld and applied to the tax obligations. With the approval of the Administrator, a Participant may satisfy the foregoing requirement by electing to have the Company withhold from delivery of Shares or by delivering already owned unrestricted shares of Common Stock, in each case, having a value equal to the amount required to be withheld or other greater amount not exceeding the maximum statutory rate required to be collected on the transaction under applicable law, as applicable to the Participant, if such other greater amount would not, as determined by the Committee, result in adverse financial accounting treatment (including in connection with the effectiveness of FASB Accounting Standards Update 2016-09). Such Shares shall be valued at their Fair Market Value on the date of which the amount of tax to be withheld is determined. Fractional share amounts shall be settled in cash. Such an election may be made with respect to all or any portion of the Shares to be delivered pursuant to an Award. The Company may also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy its withholding obligation with respect to any Option or other Award.

Section 16. Dividends; Dividend Equivalents.

Notwithstanding anything in this Plan to the contrary, to the extent that an Award contains a right to receive dividends or dividend equivalents while such Award remains unvested, such dividends or dividend equivalents will be accumulated and paid once and to the extent that the underlying Award vests.

Section 17. Non-United States Employees.

Without amending the Plan, the Administrator may grant Awards to eligible persons residing in non-United States jurisdictions on such terms and conditions different from those specified in the Plan, including the terms of any award agreement or plan, adopted by the Company or any Subsidiary thereof to comply with, or take advantage of favorable tax or other treatment available under, the laws of any non-United States jurisdiction, as may in the judgment of the Administrator be necessary or desirable to foster and promote achievement of the purposes of the Plan and, in furtherance of such purposes the Administrator may make such modifications, amendments, procedures, subplans and the like as may be necessary or advisable to comply with provisions of laws in other countries or jurisdictions in which the Company or its Subsidiaries operates or has employees.

Section 18. Transfer of Awards.

No purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any Award or any agreement or commitment to do any of the foregoing (each, a “Transfer”) by any holder thereof in violation of the provisions of the Plan or an Award Agreement will be valid, except with the prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of the Administrator. Any purported Transfer of an Award or any economic benefit or interest therein in violation of the Plan or an Award Agreement shall be null and void ab initio, and shall not create any obligation or liability of the Company, and any person purportedly acquiring any Award or any economic benefit or interest therein transferred in violation of the Plan or

an Award Agreement shall not be entitled to be recognized as a holder of such Shares. Unless otherwise determined by the Administrator in accordance with the provisions of the immediately preceding sentence, an Option may be exercised, during the lifetime of the Participant, only by the Participant or, during any period during which the Participant is under a legal disability, by the Participant’s guardian or legal representative.

Section 19. Continued Employment.

The adoption of the Plan shall not confer upon any Eligible Recipient any right to continued employment or service with the Company or an Affiliate thereof, as the case may be, nor shall it interfere in any way with the right of the Company or an Affiliate thereof to terminate the employment or service of any of its Eligible Recipients at any time.

Section 20. Effective Date and Approval Date.

The Plan was originally effective as of July 20, 2016 and amended on May 30, 2019 and the Plan, as amended and restated hereby, will be effective as of June 16, 2021 (the “Effective Date”). The Plan will be unlimited in duration and, in the event of Plan termination, will remain in effect as long as any Shares awarded under it are outstanding and not fully vested; provided, however, that no Awards will be made under the Plan on or after June 16, 2031. No Option that is intended to be an Incentive Stock Option may be granted under the Plan until the Approval Date. If the Approval Date does not occur within twelve (12) months after the Effective Date, then no Options that are intended to be Incentive Stock Options may be granted under the Plan.

Section 21. Code Section 409A.

The intent of the parties is that payments and benefits under the Plan be either exempt from Code Section 409A or comply with Code Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and be administered consistent with such intent. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Code Section 409A shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in the Plan, to the extent required in order to avoid accelerated taxation and/or tax penalties under Code Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided upon a “separation from service” to a Participant who is a “specified employee” shall be paid on the first business day after the date that is six (6) months following the Participant’s separation from service (or upon the Participant’s death, if earlier). In addition, for purposes of the Plan, each amount to be paid or benefit to be provided to the Participant pursuant to the Plan, which constitute deferred compensation subject to Code Section 409A, shall be construed as a separate identified payment for purposes of Code Section 409A. Nothing contained in the Plan or an Award Agreement shall be construed as a guarantee of any particular tax effect with respect to an Award. The Company does not guarantee that any Awards provided under the Plan will be exempt from or in compliance with the provisions of Code Section 409A, and in no event will the Company be liable for any or all portion of any taxes, penalties, interest or other expenses that may be incurred by a Participant on account of any Award being subject to, but not in compliance with, Code Section 409A.

Section 22. Erroneously Awarded Compensation.

The Plan and all Awards issued hereunder shall be subject to any compensation recovery and/or recoupment policy adopted by the Company to comply with applicable law, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or to comport with good corporate governance practices, as such policies may be amended from time to time.

Section 23. Governing Law.

The Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law of such state.

Section 24. Plan Document Controls.

The Plan and each Award Agreement constitute the entire agreement with respect to the subject matter hereof and thereof; provided, that in the event of any inconsistency between the Plan and such Award Agreement, the terms and conditions of the Plan shall control.
