William D. Sullivan, the current Chairman of our Board of Directors, will retire from the board upon the expiration of his term at the upcoming Annual Meeting. Our board determined that John F.

Luna would succeed Mr. Glick as Chairman of the Nominating, Governance and Sustainability Committee immediately following the Annual Meeting.

Below is a list of our 2021 Named Executive Officers, or “NEOs,” and select 2021 compensation highlights. Our executive compensation program reflects a fundamental belief that compensation should be competitive with the broad market in which we compete for executive talent, and commensurate with the performance of the individual executives and the Company. During 2021, we increased the portion of total target direct compensation that is performance-based for our Chief Executive Officer, Mr. Murphy, and our Chief Financial Officer, Mr. Serrano, further strengthening the alignment of their compensation with the long-term interests of our stockholders. For additional information on the 2021 compensation of our NEOs, please refer to the Compensation Discussion and Analysis (“CD&A”), beginning on page 40.

Winkler III, each a~~Sullivan, the current ~~member~~Chairman of our Board of Directors, will retire from the board upon the expiration of ~~their~~his term at the upcoming Annual Meeting, and therefore, ~~have~~has not been nominated for reelection. ~~Immediately~~Mr. Williams was appointed to the Board of Directors in 2021 consistent with a Cooperation Agreement, dated as of March 24, 2021, by and among the Company, Bradley L. Radoff and The Radoff Family Foundation.

Our board determined that John F. Glick, currently the Chairman of the Nominating, Governance and Sustainability Committee, would succeed Mr. Sullivan as Chairman of our Board of Directors and Gina A. Luna would succeed Mr. Glick as Chairman of the Nominating, Governance and Sustainability Committee immediately following the Annual Meeting. Also, immediately following the Annual Meeting, the Board of Directors expects to set the size of the board at seven directors. Proxies solicited hereby cannot be voted for a greater number of persons than the nominees for director set forth below.

Our Board of Directors believes that each director nominee for election at the Annual Meeting is highly qualified. The director nominees’ biographies (below) describe the specific experience, qualifications, attributes, and skills that have been considered by the Nominating, Governance and Sustainability Committee and contributed to such individuals’ being nominated for our Board of Directors. As their biographies indicate, all the director nominees possess significant leadership and professional experience, knowledge, including energy industry knowledge, and skills that qualify them for service on our board. Each director, other than Mr. Murphy, our President and Chief Executive Officer, satisfies the independence requirements under the listing standards of the New York Stock Exchange (“NYSE”). All directors satisfy the criteria stated in our Corporate Governance Guidelines and possess the personal characteristics essential for the proper and effective functioning of our board. Mr. Williams was appointed to the Board in 2021 and is a director nominee for election at the Annual Meeting, as consistent with a Cooperation Agreement, dated as of March 24, 2021, by and among the Company, Bradley L. Radoff and The Radoff Family Foundation.

The terms of office of each of the ~~nine~~eight current directors will expire at the time of the Annual Meeting. The Nominating, Governance and Sustainability Committee of the Board of Directors has recommended, and the Board of Directors has nominated and urges you to vote “FOR”, the election of the seven persons listed below who have been nominated to serve one-year terms as directors. Each of the nominees has consented to be named in this Proxy Statement and to serve as a director, if elected.

There are no family relationships between any of our directors and executive officers. Except for the Cooperation Agreement, dated as of March 24, 2021, and included as an exhibit to the Company’s Current Report on Form 8-K filed with the SEC on March 26, 2021, there are no other arrangements or understandings between any of our directors and any other person pursuant to which any person was selected as a director.

A plurality vote is required for the election of directors in Proposal No. 1. This means that, if a quorum is present at the Annual Meeting, the seven nominees receiving the greatest numbers of “FOR” votes will be elected to serve as directors. Please see the "General Information About the Meeting and Voting" section in this Proxy Statement for additional information.

It is intended that the proxies solicited hereby will be voted “FOR” the election of such nominees, unless the authority to do so has been withheld by you. If, at the time of the Annual Meeting, any of the nominees should be unable or decline to serve, the discretionary authority provided in the proxy will enable the proxy holder to vote for a substitute nominee of the Board of Directors. The Board of Directors has no reason to believe that any substitute nominee will be required.

Majority Vote Policy: Our Corporate Governance Guidelines provide that in an uncontested election (that is, an election where the number of nominees is not greater than the number of directors to be elected), any nominee who receives a greater number of votes WITHHELD for his or her election than votes FOR such election shall, following certification of the stockholder vote, unless such nominee has previously submitted an irrevocable resignation in accordance with the majority vote policy, promptly tender his or her resignation to the Chairman of the Board of Directors. The Nominating, Governance and Sustainability Committee is required to recommend to the Board of Directors whether such tendered resignation should be accepted or rejected. The Board of Directors will then determine whether to accept or reject the tendered resignation. Following the Board of Director’s decision on the Nominating, Governance and Sustainability Committee’s recommendation, we will promptly disclose the Board of Director’s decision and decision- making process regarding a tendered resignation in a document filed with the Securities and Exchange Commission (the “SEC”). Each of the director nominees has previously submitted an irrevocable resignation letter. Please read our Corporate Governance Guidelines posted in the Corporate Governance section of the Investor Relations area of our website at www.tetratec.com for more information regarding our majority vote policy.

PROPOSAL NO. 2 – Ratification of Selection of Independent Registered Public Accounting Firm

Proposal No. 2 — Ratification of Selection of Independent Registered Public Accounting Firm

Proposal No. 2 requests stockholder approval of the Audit Committee’s selection of the firm of Grant Thornton LLP (“GT”) as our independent registered public accounting firm, or “independent auditors”, for the year ending December 31, ~~2021.~~2022.

As reported on a Current Report on Form 8-K filed on June 18, 2020 (the “Change in Auditor 8-K"), effective June 15, 2020, the Audit Committee dismissed Ernst & Young LLP ("EY") as the Company’s independent registered public accounting firm and appointed GT to serve in this role for the fiscal year ended December 31, 2020. For more information, see the Change in Auditor 8-K filed on June 18, 2020.

EY audited the consolidated financial statements of the Company for the fiscal years ended December 31, 2018 and December 31, 2019. EY's audit reports for each of these fiscal years did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principle.

During the fiscal years ended December 31, 2018 and December 31, 2019 and during the subsequent interim period from January 1, 2020 through June 15, 2020, (i) there were no disagreements with EY on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures that, if not resolved to EY's satisfaction, would have caused EY to make reference to the subject matter of the disagreement in connection with its reports and (ii) there were no "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided EY with a copy of the Change in Auditor 8-K and requested EY to furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements contained in the Change in Auditor 8-K. The Company received the requested letter from EY, and a copy of EY’s letter was attached as Exhibit 16.1 to the Change in Auditor 8-K.

During the fiscal years ended December 31, 2018 and December 31, 2019 and during the subsequent interim period from January 1, 2020 through June 15, 2020, neither we nor anyone on our behalf consulted GT regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our financial statements, and neither a written report nor oral advice was provided to us that GT concluded was an important factor considered by us in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any matter that was either the subject of a "disagreement" (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a "reportable event" (as defined in Item 304(a)(1)(v) of Regulation S-K).

~~PROPOSAL NO. 2 – Ratification of Selection of Independent Registered Public Accounting Firm~~

The Audit Committee evaluates the selection of the independent auditors each year and has selected GT for the current year. GT has served as our independent auditors since June 2020. The Audit Committee concluded that many factors contribute to the continued support of GT’s independence, such as the oversight of the Public Company Accounting Oversight Board (“PCAOB”) through the establishment of audit, quality, ethics, and independence standards, in addition to conducting audit inspections, the mandating of reports on internal control over financial reporting, PCAOB requirements for audit partner rotation, and limitations imposed by regulation and by our Audit Committee on non-audit services provided by GT. The Audit Committee reviews and pre-approves all audit and non-audit services to be performed by GT as well as reviews and approves the fees charged by GT for such services. The Audit Committee pre-approved all audit and ~~non-services~~non-audit services performed by EYGT during the last two fiscal years. In its review and pre-approval of non-audit service fees, the Audit Committee considers, among other factors, the possible impact of the performance of such services on the auditors’ independence. In addition, under the auditor independence rules, GT reviews its independence each year and delivers to the Audit Committee a letter addressing matters prescribed in those rules. Please see the Audit Committee Report on page 4235 for additional information regarding the Audit Committee’s evaluation of GT.

~~Audit~~In accordance with SEC rules, audit partners for independent registered public accounting firms are also subject to rotation requirements that limit the number of consecutive years an individual partner may serve in certain roles. For lead and ~~Other Professional Fees~~

~~The following table presents~~concurring audit partners, the ~~aggregate fees billed for professional services rendered by GT and EY for~~maximum is five consecutive years of service. We select the ~~last two fiscal years:~~

~~Fees for services rendered by Grant Thornton LLP to the Company’s current~~lead partner from our independent registered public accounting firm pursuant to this rotation policy following meetings with potential candidates and discussions between the Audit Committee and management.

The Audit Committee considers, among other factors, the fact that we require global, standardized, and well-coordinated services, not only for ~~each~~audit purposes, but for other non-audit service items, including statutory audits and various regulatory certification items. Some of ~~the following categories~~these services are provided to us by multinational audit and accounting firms other than GT. A change in our independent auditor may require us to replace one or more of ~~services for the fiscal years ended December 31, 2020~~these other multinational service providers and ~~2019, are set forth below:~~

~~(1) Consists solely~~could significantly disrupt our business due to a loss of ~~fees for tax compliance services~~cumulative knowledge in ~~all periods.~~

~~Fees for services rendered by Ernst & Young LLP to the Company’s prior independent registered public accounting firm, for each~~such service providers’ areas of ~~the following categories of services for the fiscal years ended December 31, 2020 and 2019 are set forth below:~~

~~(1) Consists primarily of additional fees for an employee benefit plan audit in 2019 that was completed in 2020.~~

~~PROPOSAL NO. 2 – Ratification of Selection of Independent Registered Public Accounting Firm~~expertise.

The Board of Directors recommends that you vote “FOR” ratification and approval of the appointment of GT as our independent registered public accounting firm for the ~~2021~~2022 fiscal year, and proxies returned will be so voted unless contrary instructions are indicated thereon.

As a matter of good corporate governance, the Board of Directors submits the selection of the independent registered public accounting firm to our stockholders for ratification. If our stockholders do not ratify the

PROPOSAL NO. 2 – Ratification of Selection of Independent Registered Public Accounting Firm

appointment, the Audit Committee may reconsider its selection of the firm as our independent registered public accounting firm for the year ending December 31, ~~2021,~~2022, but the Audit Committee may also elect to retain the firm. Even if the selection is ratified, the Audit Committee in its discretion may appoint a different independent registered public accounting firm at any time during the year if the committee determines that such change would be appropriate. Representatives of GT are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they desire to do so and to respond to appropriate questions from stockholders.

Approval of Proposal No. 2 requires the affirmative vote of a majority of the common shares represented in person or by proxy and entitled to vote on the proposal at the ~~2021~~2022 Annual Meeting. Please see the "General Information About the Meeting and Voting" section in this Proxy Statement for additional information.

In Proposal No. 3, we are asking our stockholders to approve, on an advisory basis, the compensation of our named executive officers (collectively, the “Named Executive Officers” or “NEOs”) pursuant to Section 14A of the Exchange Act, as disclosed in this Proxy Statement in accordance with SEC rules. While this vote is not binding on our Company, the results of the votes on this proposal will be carefully considered by the Board of Directors and the Human Capital Management and Compensation Committee (“HCMCC”) of our Board of Directors when making future executive compensation decisions. The next such vote will occur at the ~~2022~~2023 Annual Meeting of ~~Stockholders~~Stockholders.

The following are some of the key topics discussed in greater detail in the CD&A and in other sections of this Proxy Statement, and stockholders are encouraged to read these other sections.

Our Board of Directors believes that our compensation program is effective in implementing our compensation philosophy and furthering our strategic goals and objectives. Pursuant to SEC rules, we are asking our stockholders to approve the compensation of our NEOs as disclosed in the CD&A (beginning on page ~~47)~~40), the compensation tables (beginning on page ~~68)~~59) and the narrative discussion following the compensation tables. This advisory stockholder vote, commonly known as “say-on-pay,” gives you as a stockholder the opportunity to approve or not approve our executive compensation program and policies through the following resolution:

“RESOLVED, that the stockholders of TETRA Technologies, Inc. approve, on an advisory basis, the compensation of its named executive officers as disclosed in the Company’s ~~2021~~2022 Proxy Statement pursuant to the executive compensation disclosure rules of the Securities and Exchange Commission, which disclosure includes the Compensation Discussion and Analysis, the compensation tables and related narrative disclosure contained in this Proxy Statement.”

The Board of Directors recommends that you vote “FOR” approval of the named executive officer compensation as disclosed pursuant to the executive compensation disclosure rules of the SEC, including in the Compensation Discussion and Analysis, the compensation tables and related narrative discussion as contained in this Proxy Statement. Proxies returned will be so voted unless contrary instructions are indicated thereon.

Approval of Proposal No. 3, on an advisory basis, requires the affirmative vote of a majority of the common shares represented in person or by proxy and entitled to vote on the proposal at the annual meeting of stockholders. Please see the "General Information About the Meeting and Voting" section in this Proxy Statement for additional information.

~~PROPOSAL NO.~~Proposal No. 4 – ~~Approval of the First Amended and Restated 2018 Equity Incentive Plan~~Shareholder Proposal

Proposal No. 4 — ~~Approval of the First Amended and Restated 2018~~Stockholder Proposal

In accordance with SEC rules, we have set forth below a shareholder proposal and supporting statement from Kenneth Steiner of 14 Stoner Ave., 2M, Great Neck, NY 11021-2100, who has indicated he is the beneficial owner of at least 1,000 shares of our common stock since at least September 1, 2018 and intends for the following proposal to be presented at the 2022 Annual Meeting. In accordance with Rule 14a-8(h) of the Exchange Act, the shareholder proposal is required to be voted on at the 2022 Annual Meeting only if properly presented by the shareholder proponent or his qualified representative at the meeting. The text of the shareholder’s resolution and the statement that the shareholder furnished to us in support thereof appear below, exactly as submitted, and we are not responsible for inaccuracies or omissions therein.

RESOLVED, Shareholders request that our board take each step necessary so that each voting requirement in our charter and bylaws (that is explicit or implicit due to default to state law) that calls for a greater than simple majority vote be eliminated, and replaced by a requirement for a majority of the votes cast for and against applicable proposals, or a simple majority in compliance with applicable laws. If necessary this means the closest standard to a majority of the votes cast for and against such proposals consistent with applicable laws. This includes any existing supermajority vote requirement that result from default to state law and can be subject to elimination.

Shareholders are willing to pay a premium for shares of companies that have excellent corporate governance. Supermajority voting requirements have been found to be one of 6 entrenching mechanisms that are negatively related to company performance according to “What Matters in Corporate Governance” by Lucien Bebchuk, Alma Cohen and Allen Ferrell of the Harvard Law School. Supermajority requirements are used to block initiatives supported by most shareholders but opposed by a status quo management.

This proposal topic won from 74% to 88% support at Weyerhaeuser, Alcoa, Waste Management, Goldman Sachs, FirstEnergy, McGraw-Hill and Macy’s. The proponents of these proposals included Ray T. Chevedden and William Steiner. The votes would have been higher than 74% to 88% if more shareholders had access to independent proxy voting advice.

Church & Dwight shareholders gave 99% support to a 2020 proposal on this same topic. This proposal topic also won 99%-support at the 2021 ConocoPhillips annual meeting.

There should be urgency in reforming our outdated corporate governance given that our stock was at $12 in 2014.

The use of equity-based awards under the Tetra Technologies, Inc. 2018 Equity Incentive Plan (the “2018 Plan”) is a key component of our compensation program. The ability to grant equity-based awards is critical to attracting and retaining highly qualified individuals. The Board believes it is in the best interests of the Company and our stockholders for those individuals to have an ownership interest in the Company in recognition of their present and potential contributions and to align their interests with those of our stockholders.

~~The current number of shares of our common stock available for grants under the 2018 Plan is insufficient to meet the goals of our compensation program going forward. Accordingly, our~~ Board of Directors ~~has approved and recommends that our stockholders approve~~is not recommending a vote for or against Proposal No. 4. Rather, the First Amended and Restated 2018 Equity Incentive Plan (the “Amended 2018 Plan”) to increase the number of shares of common stock available for grant and to make certain other changes to the 2018 Plan as described below. If the proposed Amended 2018 Plan is approved by our stockholders, the 2018 Plan will provide us with additional shares with which to create incentives for our employees, officers, directors and consultants and will enable us to provide a competitive mix of compensation to our key employees.

~~The~~ Board of Directors ~~recommends that you vote~~ “~~FOR~~”is interested in the ~~Amended 2018 Plan,~~viewpoints of the Company’s stockholders and ~~proxies returned~~ will ~~be so voted unless contrary instructions are indicated thereon.~~

~~Historically~~ No. 4, together with additional stockholder input received in the Company has maintained both the 2018 Plan and the 2018 Non-Employee Director Equity Incentive Plan (the “Director Plan”), a stand-alone equity plan for non-employee directors. The 2018 Plan and the Director Plan were approved by stockholders at the 2018 annual meeting of stockholders. 6,365,000 sharescourse of our ~~common stock were previously reserved for issuance under the 2018 Plan~~regular stockholder engagement program, in determining what actions it will take. Stockholders should note that this proposal is advisory in nature only and ~~335,000 shares~~approval of ~~our common stock were previously reserved for issuance under the Director Plan.~~

We also have grants outstanding under our 2011 Long Term Incentive Compensation Plan (the “2011 Plan”) and our 2007 Long Term Incentive Compensation Plan (the “2007 Plan”) which continue to be governedthis proposal would not, by the applicable terms and conditions of the respective plan, although no further options or awards may be granted under such plans. We may also grant inducement equity awards to new employees under our 2018 Inducement Restricted Stock Plan (the “Inducement Plan”), more fullyitself, implement a majority voting standard as described on page 17. For additional information regarding equity-based awards previously granted by us under the 2011 Plan, 2007 Plan and the Inducement Plan, see Note 14 to our consolidated financial statements on Form 10-K for the year ended December 31, 2020.

On March 31, 2021, our Board of Directors, at the recommendation of our Human Capital Management and Compensation Committee (“Committee”), approved the Amended 2018 Plan, subject to approval by our stockholders at our 2021 annual meeting, in order to both (i) increase the number of shares of our common stock available for grant by 5,500,000 shares and (ii) ease the administrative burden of maintaining two equity incentive plans by permitting non-employee directors to participate in the ~~Amended 2018 Plan. If approved by our stockholders, the aggregate number of shares of our common stock that may be the subject of awards and issued under the Amended 2018 Plan is 11,865,000.~~

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~Audit Committee Report

~~If the proposed amendment~~Directors and ~~restatement of the 2018 Plan is approved by~~ our stockholders ~~the Director Plan will be terminated as~~would need to take subsequent action to amend our Certificate of ~~the effective date of the Amended 2018 Plan~~Incorporation and ~~there will be no further awards granted under the Director Plan.

In addition, no shares remaining available for future awards under the Director Plan as of the effective date of the Amended 2018 Plan will become available for awards under the Amended 2018 Plan. If the Amended 2018 Plan is not approved by stockholders, annual awards to our non-employee directors will continue to be made under the Director Plan. Bylaws.

The ~~Amended 2018 Plan makes certain changes to the terms of the 2018 Plan, including:~~

Stockholder approval of the Amended 2018 Plan is being sought in order to satisfy the stockholder approval requirements of the New York Stock Exchange and Section 422 of the Internal Revenue Code (the “Code”) to enable options granted under the Amended 2018 Plan to qualify as incentive stock options.

If the Amended 2018 Plan is not approved by our stockholders, the 2018 Plan and Director Plan will remain in effect, and we will remain subject to the existing share reserve under the 2018 Plan and Director Plan.

~~If the stockholders approve the Amended 2018 Plan, it will be effective as of May 26, 2021. A copy of the Amended 2018 Plan is attached to this Proxy Statement as~~ ~~Appendix A~~. In Appendix A, we have shown the changes to the 2018 Plan that will result from approval of the Amended 2018 Plan, with deletions indicated by strikeouts and additions indicated by underlining. The following description of the Amended 2018 Plan is not intended to be complete and is qualified by reference to Appendix A, which contains the complete text of the Amended 2018 Plan.

If our stockholders approve this proposal, we intend to file, pursuant to the Securities Act, a registration statement on Form S-8 to register additional shares available for delivery under the Amended 2018 Plan.

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

~~In setting the proposed number of shares reserved and issuable under the Amended 2018 Plan, the Human Capital Management and Compensation Committee and our~~ Board of Directors ~~considered a number of factors, including the following:~~

~~In the table below, we provide information about the shares of our common stock that may~~takes no position and makes no recommendation on this proposal. Proxies signed but where no voting instruction is indicated will be ~~issued under the 2018 Plan as of December 31, 2020, the end of our most recent fiscal year.~~

On August 1, 2012, Elijio V. Serrano was appointed by our Board of Directors to the positions of Senior Vice President and Chief Financial Officer. In connection with Mr. Serrano’s appointment, the Board of Directors authorized the grant to Mr. Serrano of an employment inducement award of 79,051 nonqualified stock options and 46,898 shares of restricted stock to be effective as of August 15, 2012. The exercise price of the nonqualified stock options is $6.60, which is equal to the closing price per share of our common stock on the New York Stock Exchange on August 15, 2012. The nonqualified stock options are fully vested and the award will expire on August 15, 2022.

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~voted ABSTAIN.

The TETRA Technologies, Inc. 2018 Inducement Restricted Stock Plan was adopted effective as of February 12, 2018. The purpose of the plan is to attract and retain the best available individuals for positions of substantial responsibility by providing a material inducement for such individuals to enter into employment with us or any of our affiliates. In connection with the employment of Brady M. Murphy, currently our President and Chief Executive Officer, the Board of Directors authorized the grant to Mr. Murphy of an employment inducement award of 502,513 shares of restricted stock, effective as of February 12, 2018. Fifty percent of the shares of restricted stock vested on the one-year anniversary date of the grant, 25% vested on the second-year anniversary date of the grant, and the remaining 25% of the shares of restricted stock vested on the third-year anniversary of the date of grant. In addition, in connection with our acquisition of Swiftwater Energy Services, LLC, the Board of Directors authorized the grant of awards totaling 420,992 shares of restricted common stock to thirteen persons as an inducement to their employment with TETRA on February 28, 2018. Subject to their continued employment with us and other terms and conditions set forth in the Restricted Stock Award Agreement between us and each of the individuals, the shares of restricted stock vested 100% on the third-year anniversary of the date of grant. There are 76,495 shares available for future awards under the 2018 Inducement Restricted Stock Plan.

To facilitate approval of the Amended 2018 Plan, we are providing updated information as of our record date, March 29, 2021. As of the close of business on March 29, 2021, there were 126,407,014 shares of our common stock issued and outstanding. The closing sale price of a share of our common stock on the New York Stock Exchange on that date was $2.47. The following table summarizes information regarding awards outstanding and shares remaining available for grant under the 2018 Plan, the Director Plan, the 2011 Plan, the 2007 Plan and under the Inducement Plan, as of ~~the close of business on~~ ~~March 29, 2021:~~

The Human Capital Management and Compensation Committee is focused on using equity to compensate executives in a manner that links executive and stockholder interests while focusing on the overall dilutive impact of that equity. The Human Capital Management and Compensation Committee balances the need to attract, motivate, and retain the level of executive talent required to execute the business strategy and achieve operational excellence at TETRA with the need to carefully consider and manage the usage of equity and the resulting equity dilution.

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

We manage our long-term dilution by limiting the number of shares subject to equity awards that we grant annually. The “burn rate” calculated below shows the dilution of our outstanding equity awards on our total outstanding shares. We have calculated the burn rate under our equity compensation program for the past three years, as set forth on the following table:

~~Estimated duration of shares available for issuance under the Amended 2018 Plan~~ - Based on the 11,865,000 total shares to be reserved under the Amended 2018 Plan and certain assumptions described below, we expect that the share reserve of the Amended 2018 Plan will cover awards for approximately two years. Our estimation of the duration of the Amended 2018 Plan is based on a number of assumptions including the anticipated amount of annual grants under the Amended 2018 Plan, the rate at which shares will be returned to the Amended 2018 Plan reserve through forfeitures, cancellations and the like, and our future stock price performance. While the Committee believes that the assumptions utilized are reasonable, future share usage will differ to the extent that actual events differ from our assumptions.

The potential dilution from the 11,865,000 share reserve of the Amended 2018 Plan is approximately 8.4% (calculated as the share reserve divided by the fully-diluted shares outstanding as of the Record Date). Our Board of Directors has considered this potential dilution level and believes it is within normal range for similarly situated companies.

In addition to overall dilution, in recommending the increase to the share reserve under the Amended 2018 Plan the Human Capital Management and Compensation Committee considered annual dilution from our equity incentive plans, as shown on the following table:

~~The Amended 2018 Plan includes a number of features that we believe are consistent with the interests of our stockholders and sound corporate governance practices, including the following:~~

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

The major features of the Amended 2018 Plan are summarized below. The summary is qualified in its entirety by reference to the full text of the Amended 2018 Plan, which is attached to this Proxy Statement as Appendix A.

~~Eligible Participants~~ - Employees and consultants of the Company or any subsidiary and non-employee members of our Board of Directors will be eligible to receive awards under the 2018 Plan. As of March 29, 2021, there were approximately 1,077 employees of the Company and its subsidiaries, eight non-employee members of our Board of Directors (assuming stockholder approval of the director nominations is received as of such date), and an indeterminate number of consultants who would be eligible to receive awards under the 2018 Plan.

~~Administration~~ - The Amended 2018 Plan will be administered by the Administrator, which is the Board of Directors or any of its committees that may be administering the plan in accordance with the terms of the plan. To the extent consistent with applicable law, different committees may administer the Amended 2018 Plan with respect to different groups of service providers.

The Administrator has the authority to determine the fair market value of awards, persons to whom awards will be granted, the timing of awards, the type and number of shares covered by each award, the terms, conditions, performance criteria and restrictions of the awards as well as the manner in which awards are paid and settled. The Administrator may also prescribe, amend, or rescind rules to administer the Amended 2018 Plan, adopt special provisions applicable to certain awards (including awards to foreign employees), interpret the Amended 2018 Plan and any related award agreement, reconcile any inconsistency, correct any defect or supply an omission in the Amended 2018 Plan and any related award agreement, determine in what circumstances an award shall be forfeited, accelerate the vesting or extend the exercise period of an award, otherwise amend the terms of outstanding awards to the extent permitted under the Amended 2018 Plan, and require or permit the deferral of the settlement of an award. Unless an amendment to the terms of an award is necessary to comply with applicable tax laws, if a participant’s rights under an impacted award would be adversely affected by such an amendment, the participant must consent to the amendment.

Except in connection with equity restructurings and other situations in which share adjustments are specifically authorized, the Amended 2018 Plan prohibits the Administrator from repricing any outstanding option or SAR awards without the prior approval of our stockholders.

Subject to certain limitations set forth in the Amended 2018 Plan, the Administrator may also modify the terms of awards under the Amended 2018 Plan with respect to participants who reside outside of the United States or who are employed by a non-U.S. subsidiary of the Company in order to comply with local legal or regulatory requirements.

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

~~Available Shares and Limitations on Awards~~- A maximum of 11,865,00 shares of our common stock may be the subject of awards and issued under the Amended 2018 Plan, subject to adjustment for changes in our corporate structure or shares, as described below. The shares of common stock issuable under the Amended 2018 Plan may come from our authorized but unissued shares or treasury shares. The maximum number of shares that may be subject to stock options or SARs granted to any single participant in any calendar year is 1,000,000 shares. The maximum number of shares that may be subject to restricted stock awards, restricted stock units, performance shares, performance units and other stock-based awards granted to any single participant in any calendar year is 1,000,000 shares. No non-employee director may be granted during any calendar year awards having an aggregate fair market value, determined on the date of grant, in excess of $300,000.

Shares of common stock that are issued under the Amended 2018 Plan or that are potentially issuable pursuant to outstanding awards will reduce the Amended 2018 Plan’s share reserve by one share for each share issued or issuable pursuant to an outstanding award.

Any shares of common stock subject to an award under the Amended 2018 Plan that expires, is cancelled or forfeited or is settled or paid in cash will, to the extent of such expiration, cancellation, forfeiture or cash settlement, automatically replenish the Amended 2018 Plan share reserve and become available for future awards. The following shares shall not again become available for awards or replenish the share reserve: any shares tendered or withheld to pay the exercise price of an option or to satisfy a tax withholding obligation in connection with any award; any shares repurchased by the Company using option exercise proceeds; and, any shares subject to a stock-settled SAR award that are not issued in connection with the settlement of the SAR award. Awards that may be settled solely in cash will not reduce the share reserve under the Amended 2018 Plan.

~~Share Adjustment Provisions~~ – If certain transactions occur that cause the per share value of our common stock to change, such as stock dividends, stock splits, spin-offs, rights offerings or certain recapitalizations (referred to as an “equity restructuring”), the Administrator will equitably adjust (i) the aggregate number and kind of shares or other securities issued or reserved for issuance under the Amended 2018 Plan, (ii) the number and kind of shares or other securities subject to outstanding awards, (iii) the exercise price of outstanding stock options and SAR awards, and (iv) award limitations under the Amended 2018 Plan. Other types of transactions may also impact our common stock, such as a reorganization, merger, consolidation or partial or complete liquidation of our Company. If there is such a transaction and the Administrator determines that adjustments of the type previously described in connection with the equity restructurings would be appropriate to prevent any dilution or enlargement of benefits under the Amended 2018 Plan, the Administrator may make such adjustments as it deems equitable.

~~Types of Awards~~ - The Amended 2018 Plan permits us to award stock options, SARs, restricted stock awards, restricted stock units, performance units, performance shares, other stock-based awards, and cash-based awards to eligible recipients. These types of awards are described in more detail below.

The total purchase price of the shares to be purchased upon exercise of an option will be paid in full by the participant (including provision for any applicable tax withholding) in the manner determined by the Administrator and authorized by the award agreement and the Amended 2018 Plan. Any shares delivered or withheld in payment of an exercise price will be valued at their fair market value on the exercise date and have an aggregate value equal to the purchase price of the shares being purchased.

An option will vest and become exercisable at such time, in such installments, and subject to such conditions as may be determined by the Administrator, and no option may have a term greater than 10 years from its date of grant. Until shares are issued upon exercise, no dividends or dividend equivalents may be paid or credited with respect to shares subject to an option award.

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

The aggregate fair market value of shares of our common stock with respect to which incentive stock options granted to any participant may first become exercisable during any calendar year may not exceed $100,000. Any incentive stock options that become exercisable in excess of this amount will be treated as nonqualified stock options. The maximum number of shares that may be issued upon the exercise of incentive stock option awards under the Amended 2018 Plan is 11,865,000.

~~Minimum Vesting Periods~~ – Except as described in the following sentence, all awards are subject to a minimum vesting period of one year from the date of grant. This minimum vesting requirement does not apply: (i) with respect to an acceleration of vesting upon a change in control in accordance with the Amended 2018 Plan or (ii) to awards involving an aggregate number of shares up to 5 percent of the Amended 2018 Plan’s share reserve. Generally, vesting will be suspended during any unpaid leave of absence.

~~Transferability of Awards~~ - In general, no right or interest in any award under the Amended 2018 Plan may be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than upon a participant’s death to a beneficiary designated pursuant to the plan or by will or the laws of descent and distribution and may be exercised, during the lifetime of the participant, only by the participant.

~~Performance Based Awards -~~ ~~The Amended 2018 Plan allows for performance-based awards. The performance measures specified in the Amended 2018 Plan include the following: net income; cash flow; cash flow on~~

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

investment; cash flow from operations; pre-tax or post-tax profit levels or earnings; operating income or earnings; closings; return on investment; earned value added; expenses; free cash flow; free cash flow per share; earnings; earnings per share; net earnings per share; net earnings from continuing operations; sales growth; sales volume; economic profit; expense reduction; return on assets; return on net assets; return on equity; return on capital; return on sales; return on invested capital; organic revenue; growth in managed assets; total stockholder return; stock price; stock price appreciation; EBITDA; adjusted EBITDA; return in excess of cost of capital; profit in excess of cost of capital; capital expended; working capital; net operating profit after tax; operating margin; profit margin; adjusted revenue; revenue; net revenue; operating revenue; cash provided by operating activities; net cash provided by operating activities per share; cash conversion percentage; new sales; net new sales; cancellations; gross margin; gross margin percentage; revenue before deferral; implementation or completion of critical projects; research; horsepower; horsepower utilization rate; product development; government relations; compliance; mergers; acquisitions or sales of assets or subsidiaries; health; safety; environmental; debt level; cost reduction targets; equity ratios; depreciation and amortization; G&A expense or adjusted G&A measures; charge offs; and such other criteria as established by the Committee in its sole discretion from time to time.

~~Effect of Termination of Employment~~ - Unless otherwise set forth in an applicable award agreement, if a participant ceases to be employed by or provide other services to us and our subsidiaries, awards under the Amended 2018 Plan will be treated as set forth in the Amended 2018 Plan. Unless otherwise set forth in the applicable award agreement, upon termination of a participant for any reason, all unvested and unexercisable portions of any outstanding awards will be immediately forfeited without consideration; however, the participant may exercise the currently vested and exercisable portions of his or her stock option awards within the time period specified in the award agreement. If the award agreement does not specify the time period within which the currently vested and exercisable portions of such award must be exercised, they shall be exercisable for three months following his or her termination date. Upon termination due to disability or death, the currently vested and exercisable portions of option awards may be exercised within the time period specified in the award agreement. If the award agreement does not specify the time period within which the currently vested and exercisable portions of such option must be exercised, they shall be exercisable for twelve months following his or her termination date.

~~Change in Control~~ - For purposes of the Amended 2018 Plan, a “change in control” generally refers to (i) the acquisition by a person or group of beneficial ownership of 50% or more of the combined voting power of our voting securities, (ii) the sale of all or substantially all of our assets, other than to persons who beneficially own at least 50% of the combined voting power of our voting securities or a spin-off type transaction of such assets to our stockholders, (iii) our incumbent directors ceasing to constitute a majority of our Board during any consecutive 12-month period, or (iv) a merger or consolidation of us with another corporation (unless immediately following such merger or consolidation all or substantially all of our previous holders of voting securities beneficially own more than 50% of the combined voting power of the resulting entity in substantially the same proportions). A “corporate transaction” means a transaction described in either clause (ii) or clause (iv) of the foregoing sentence.

If a change in control of the Company that involves a corporate transaction occurs, then the consequences will be as described below unless otherwise provided in an applicable award agreement or other agreement with a participant.

If and to the extent outstanding awards are continued, assumed or substituted by a successor entity, and if within 24 months after the date of a change in control a participant’s employment or other service is involuntarily terminated without cause or is terminated by the participant for good reason (as such terms are defined in the Amended 2018 Plan), (i) each of such participant’s outstanding options and SARs will become exercisable in full and remain exercisable for one year, (ii) each of such participant’s unvested awards other than options and SARs will fully vest, and (iii) to the extent vesting of an award is subject to the satisfaction of specified performance goals, such award will be deemed fully vested if the performance goals are deemed to have been satisfied at the target level of performance and the vested portion of the award at that level of performance is proportionate to the portion of the performance period elapsed prior to the participant’s termination of employment or other service. If and to the extent any outstanding award is not continued, assumed or replaced in connection with a change in control involving a corporate transaction, then (i) all such outstanding options and SARs will become fully exercisable for a period of time prior to the effective time of the corporate transaction and will then terminate at the effective time of the corporate transaction, (ii) all such awards other than options and SARs will fully vest immediately prior to the effective time of the corporate transaction, and (iii) to the extent vesting of an award is subject to the satisfaction of specified performance goals, such award will be deemed fully vested in the same manner as described above,

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

except that the proportionate vesting amount will be determined with respect to the portion of the performance period that elapsed prior to the time of the corporate transaction. Alternatively, if outstanding awards are not continued, assumed or replaced, the Committee may elect to cancel such awards at or immediately prior to the effective time of the corporate transaction in exchange for a cash payment with respect to each award in an amount equal to the excess, if any, between the fair market value of the shares subject to the award immediately prior to the effective date of such corporate transaction (which may be the fair market value of the consideration that would otherwise be received in the corporate transaction for the same number of shares) over the aggregate exercise price (if any) for the shares subject to such award (or, if there is no excess, such award may be terminated without payment). In the event of a change in control of the Company that does not involve a corporate transaction, the Committee may, in its discretion, take such action as it deems appropriate with respect to outstanding awards, which may include (i) making such adjustments or modifications to the awards then outstanding as the Committee deems appropriate, which may include acceleration of vesting in full or in part, or (ii) providing for the cancellation of any outstanding award in exchange for a payment in an amount determined in the same manner as described in the preceding paragraph. The Committee is not required to treat all awards similarly in a change in control.

~~Effective Date and Term of the Amended 2018 Plan~~ - The Amended 2018 Plan will become effective on the date it is approved by our stockholders. Unless terminated earlier, the Amended 2018 Plan will terminate on the tenth anniversary of the effective date. Awards outstanding under the Amended 2018 Plan at the time it is terminated will continue in accordance with their terms and the terms of the Amended 2018 Plan unless otherwise provided in the applicable award agreements.

~~Amendment of the Plan~~ - Our Board of Directors may amend the Amended 2018 Plan from time to time, but no amendments to the Amended 2018 Plan will be effective without stockholder approval if such approval is required under applicable laws, regulations, or stock exchange rules. Our Board of Directors also may suspend or terminate the Amended 2018 Plan at any time. No termination, suspension or amendment of the Amended 2018 Plan may materially impair the rights of any participant under a previously granted award without the consent of the affected participant, except for amendments necessary to comply with applicable laws or stock exchange rules.

~~Amendment of Awards~~ - The Administrator may amend the terms of any award subject to certain limitations, however, no such amendment may materially impair the rights of any participant under a previously granted award without the consent of the affected participant, except for amendments necessary to comply with applicable tax laws.

~~Clawback~~ - Awards are subject to forfeiture or recovery pursuant to any clawback policy we may adopt from time to time, including any clawback policy adopted to comply with applicable laws, including the provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

The following is a brief summary of certain U.S. federal income tax consequences relating to the transactions described under the Amended 2018 Plan. This summary does not purport to address all aspects of U.S. federal income taxation and does not describe state, local, or foreign tax consequences. This discussion is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”) and the Treasury Regulations issued thereunder, and judicial and administrative interpretations under the Code and Treasury Regulations, all as in effect as of the date hereof, and all of which are subject to change (possibly on a retroactive basis) or different interpretation. This information is not applicable to participants who are not subject to U.S. federal income taxation.

~~Nonqualified Stock Options~~ - A participant receiving a nonqualified stock option that has been issued with an exercise price not less than the fair market value of our common stock on the grant date will not recognize income and we will not be allowed a tax deduction at the time that the nonqualified stock option is granted. When a participant exercises a nonqualified stock option, the difference between the option price and any higher market value of the stock on the date of exercise will be ordinary income to the participant and will be claimed as a deduction for federal income tax purposes by us. When a participant disposes of shares acquired by the exercise of the nonqualified stock option, any amount received in excess of the fair market value of the shares on the date of exercise will be treated as short-term or long-term capital gain, depending upon whether the participant held the shares for more than one year following the exercise date of the option. If the amount received upon subsequent disposition of the shares is less than the fair market value of the shares on the date of exercise, the loss will be

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

~~treated as short-term or long-term capital loss, depending upon whether the participant held the shares for more than one year following the exercise date of the option.~~

~~Incentive Stock Options~~ - incentive stock options granted under the Amended 2018 Plan are intended to meet the requirements of Section 422 of the Code. A participant receiving a grant of incentive stock option will not recognize income and we will not be allowed a deduction at the time the incentive stock option is granted. When a participant exercises an incentive stock option while employed by the us or our subsidiary, or within the three-month period (one year period following termination due to disability) after termination of employment, no ordinary income will be recognized by the participant at that time (and no tax deduction will be allowed to the us) but the excess of the fair market value of the shares acquired via such exercise over the option price will be taken into account in determining the participant’s alternative minimum taxable income for purposes of the federal alternative minimum tax applicable to individuals. If the shares acquired upon exercise are not disposed of before (i) two years after the date of grant and (ii) one year after the date of transfer of the shares to the participant (~~i.e.~~, the statutory holding periods for incentive stock options), the excess of the sale proceeds over the aggregate exercise price of such shares will be long-term capital gain, and we will not be entitled to any federal income tax deduction. Except in the event of death, if the shares are disposed of prior to the expiration of the statutory holding periods for incentive stock options (referred to as a “Disqualifying Disposition”), the excess of the fair market value of such shares at the time of exercise over the aggregate exercise price (but not more than the gain on the disposition if the disposition is a transaction on which a loss, if sustained, would be recognized) will be ordinary income at the time of such Disqualifying Disposition (and we will be entitled to a federal income tax deduction in a like amount), and the balance of the gain, if any, will be capital gain (short-term or long-term depending upon whether the participant held the shares for more than one year following the exercise date of the incentive stock option). To the extent that the aggregate fair market value of stock (determined on the date of grant) with respect to which incentive stock options become exercisable for the first time during any calendar year exceeds $100,000, such excess options will be treated as nonqualified stock options.

~~Special rule if option price is paid for in common stock.~~ If a participant pays the exercise price of a nonqualified stock option or incentive stock option with previously-owned common stock of ours and the transaction is not a Disqualifying Disposition, the shares received equal to the number of shares surrendered are treated as having been received in a tax-free exchange. The shares received in excess of the number surrendered will not be taxable income if an incentive stock option is being exercised, but will be taxable as ordinary income to the extent of their fair market value if a nonqualified stock option is being exercised. The participant does not recognize income and the Company receives no tax deduction as a result of the tax-free portion of the exchange transaction. If the use of previously acquired incentive stock option shares to pay the exercise price of another incentive stock option constitutes a Disqualifying Disposition, the tax results described in the preceding paragraph will apply. The income tax treatment will apply to the shares disposed of, but will not affect the favorable tax treatment of the shares received.

~~Stock Appreciation Rights and Restricted Stock~~ -A participant receiving a grant of a stock appreciation right or a restricted stock award will not recognize income, and we will not be allowed a deduction at the time such award is granted, unless the participant makes a Section 83(b) election, as described below, with respect to a restricted stock award. While an award remains unvested or otherwise subject to a substantial risk of forfeiture, a participant will recognize compensation income equal to the amount of any dividends received and we will be allowed a tax deduction in a like amount. When an award vests or otherwise ceases to be subject to a substantial risk of forfeiture, the excess of the fair market value of the award on the date of vesting or the cessation of the substantial risk of forfeiture over the amount paid, if any, by the participant for the award will be ordinary income to the participant and will be claimed as a tax deduction for federal income tax purposes by us. Upon disposition of the shares received, the gain or loss recognized by the participant will be treated as capital gain or loss, and the capital gain or loss will be short-term or long-term depending upon whether the participant held the shares for more than one year following the vesting or cessation of the substantial risk of forfeiture. However, if the participant files a Section 83(b) election with the Internal Revenue Service within 30 days after the date of grant of restricted stock, the participant’s ordinary income, commencement of the holding period, and the tax deduction will be determined as of the date of grant. In such a case, the amount of ordinary income recognized by such participant and deductible by us will be equal to the excess of the fair market value of the award as of the date of grant over the amount paid, if any, by the participant for the award. If a Section 83(b) election is made and the participant thereafter forfeits such award, no refund or deduction will be allowed for the amount previously included in the participant’s income.

~~Other Awards~~ ~~- The current federal income tax consequences of other awards authorized under the Amended 2018 Plan generally follow certain basic patterns. Restricted stock unit awards generally result in income~~

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

recognition by a participant at the time payment of such an award is made in an amount equal to the amount paid in cash or the then-current fair market value of the shares received, as applicable. In the case of another stock-based award, a participant will generally recognize ordinary income in an amount equal to any cash received and the fair market value of any common stock received on the date of payment or delivery, provided that the award is either exempt from or complies with applicable requirements under Section 409A of the Code. In that taxable year, we will receive a federal income tax deduction in an amount equal to the ordinary income amount recognized by the participant.

~~Parachute Payments~~ - Under the “golden parachute” provisions of Section 280G of the Code, the accelerated vesting of stock options and benefits paid under other incentive awards granted under the Amended 2018 Plan in connection with a change in control of TETRA, as described under Section 280G, may be required to be valued and taken into account in determining whether participants have received compensatory payments, contingent on the change in control, in excess of certain limits under Section 280G. If these limits are exceeded, a portion of the amounts payable to the participant may be subject to an additional 20% federal tax imposed on the participant and be nondeductible to us. If a participant’s rights under the Amended 2018 Plan are accelerated as a result of a change of control and the participant is a “disqualified individual” under Section 280G, the then present value of any accelerated rights received by such participant may be included in determining whether the participant received an “excess parachute payment” under Section 280G.

~~Section 409A of the Code~~ - Section 409A of the Code applies to certain plans providing deferred compensation to employees, non-employee directors, consultants and other service providers. Section 409A could potentially apply to certain of the different types of incentive awards available under the Amended 2018 Plan. Generally, to the extent that the tax deferral of an award granted under the Amended 2018 Plan fails to meet either an exemption from the application of Section 409A, or the requirements for compliance with Section 409A, such award may be subject to taxation and tax penalties under Section 409A. We intend to structure awards granted under the Amended 2018 Plan and administer the Amended 2018 Plan in a manner that either complies with or is exempt from the requirements of Section 409A. If any Amended 2018 Plan provision or any outstanding award would result in the imposition of a tax or penalty under Section 409A, we may reform that Amended 2018 Plan provision or award (to the extent permitted by Section 409A) to avoid imposition of the tax or penalty, and no such action taken to comply with Section 409A, or an exemption thereunder, will be deemed to adversely affect the participant’s rights to the award.

~~Federal Tax Withholding~~ - Income realized by an employee upon the exercise of a nonqualified stock option or the receipt of shares under another type of award is generally subject to withholding of federal, state, and local income tax, as well as to withholding of the participant’s share of tax under the Federal Insurance Contribution Act. Because the withholding requirement applies only to employees, a non-employee participant who receives an award under the Amended 2018 Plan is not subject to tax withholding by us.

To satisfy federal income tax withholding requirements, we have the right to require that, as a condition to delivery of any certificate for common stock, the participant remit to us an amount sufficient to satisfy the withholding requirements. Alternatively, we may withhold a portion of the shares (valued at fair market value) that otherwise would be issued to the participant to satisfy all or part of the withholding tax obligations. Tax withholding does not represent an increase in the participant’s total income tax obligation since it is fully credited toward the participant’s tax liability for the year. Additionally, withholding does not affect the participant’s basis in shares of common stock received under the Amended 2018 Plan.

~~ERISA~~ - The Amended 2018 Plan is not subject to any of the provisions of the Employee Retirement Income Security Act of 1974. The Amended 2018 Plan is not a qualified plan under Section 401(a) of the Code.

The Amended 2018 Plan will not become effective until it is approved by our stockholders and the Administrator has not yet approved any awards under, or subject to, the Amended 2018 Plan. Because all awards under the Amended 2018 Plan are discretionary with the Administrator, neither the number nor types of Amended 2018 Plan awards to be received by or allocated to particular participants or groups of participants is presently determinable, although the Company intends to make awards under the Amended 2018 Plan to such groups consistent with its existing compensation practices. Therefore, the New Plan Benefits Table and information regarding future stock option grants that could be granted pursuant to the Amended 2018 Plan is not provided. Information regarding

~~PROPOSAL NO. 4 – Approval of the First Amended and Restated 2018 Equity Incentive Plan~~

~~awards made under the 2018 Plan during fiscal 2020 to our named executive officers is provided under “Grants of Plan-Based Awards” on page 69.~~

~~The following table states the amount of options that have been previously granted pursuant to the 2018 Plan as of March 29, 2021:~~

~~Pursuant to our Bylaws, approval~~Approval of ~~the amended and restated Amended 2018 Plan~~Proposal No. 4, on an advisory basis, requires the affirmative vote of a majority of the common shares represented in person or by proxy and entitled to vote on the proposal at the ~~2021 Annual Meeting. In addition~~annual meeting of stockholders. Abstentions will be counted as present and entitled to ~~the~~ vote ~~required by our Bylaws described above, under the New York Stock Exchange (“NYSE”) rules, approval of the amended and restated Amended 2018 Plan requires approval of a majority of votes cast~~ on the proposal and will therefore have the same effect as a vote against the proposal.

Broker non-votes will have no impact on this proposal if a quorum is present. Please see the "General Information About the Meeting and Voting" section in this Proxy Statement for additional information.

If the stockholders approve the amended and restated Amended 2018 Plan, it will be effective as of May 26, 2021. A copy of the amended and restated Amended 2018 Plan is attached to this Proxy Statement as Appendix A. The preceding description of the amended and restated Amended 2018 Plan is not intended to be complete and is qualified by reference to Appendix A, which contains the complete text of the amended and restated Amended 2018 Plan.

The Board of Directors has adopted Corporate Governance Guidelines that address applicable NYSE corporate governance listing requirements and various other corporate governance matters. The Board of Directors believes the Corporate Governance Guidelines assist in ensuring that:

Our Corporate Governance Guidelines provide for a majority vote principle in connection with the election of our directors. This means that in an uncontested election (that is, an election where the number of nominees is not greater than the number of directors to be elected), any nominee who receives a greater number of votes “withheld” from his or her election than votes “for” his or her election must promptly tender his or her resignation to the Chairman of the Board unless such nominee has previously submitted an irrevocable letter of resignation in accordance with our Corporate Governance Guidelines. The Corporate Governance Guidelines also provide that the Board of Directors may require, in order for any incumbent director to become a nominee for further service on the Board of Directors, that such incumbent director submit to the Board of Directors an irrevocable letter of resignation. The irrevocable letter of resignation is conditioned upon, and will not become effective until there has been (i) a failure by that nominee to receive more votes “for” his or her election than votes “withheld” from his or her election in any uncontested election of directors and (ii) acceptance of the resignation by the Board of Directors. In the event a director receives a greater number of votes “withheld” from his or her election than “for” his or her election, the Nominating, Governance and Sustainability Committee will make a recommendation to the Board of Directors regarding the action to be taken with respect to the tendered resignation. A director whose resignation is being considered will not participate in any committee or Board of Directors meetings where his or her resignation is being considered. The Board of Directors will consider the Nominating, Governance and Sustainability Committee’s recommendation and decide whether to accept the tendered resignation within 90 days following the certification of the stockholder vote, and the Board of Directors will promptly and publicly disclose its decision. Each of the nominees for election to the Board of Directors has submitted an irrevocable letter of resignation in accordance with our Corporate Governance Guidelines.

The following governance documents are available in the Corporate Governance section of the Investor Relations area of our website at www.tetratec.com and are also available upon written request addressed to Corporate Secretary, TETRA Technologies, Inc., 24955 Interstate 45 North, The Woodlands, Texas 77380:

If any substantive amendments are made to the Code of Ethics for Senior Financial Officers, the nature of such amendment will be disclosed on our website. In addition, if a waiver from either the Code of Business Conduct or the Code of Ethics for Senior Financial Officers is granted to an executive officer, director, or principal accounting officer, the nature of such waiver will be disclosed on our website.

Director Independence and Transactions Considered in Independence Determinations

Director Independence. The NYSE listing standards and our Corporate Governance Guidelines require our Board of Directors to be comprised of at least a majority of independent directors. Our Board of Directors determines independence in accordance with the listing requirements of the NYSE, taking into consideration such facts and circumstances as it considers relevant. In order to assist the Board of Directors in making its determination of whether directors are independent, each director completed and delivered to us a questionnaire designed to solicit accurate and complete information that may be relevant in making such independence determinations. The Board of Directors, with the assistance of the Nominating, Governance and Sustainability Committee, reviewed summaries of responses to such questionnaires and such other information considered relevant with respect to the existence of any relationships between a director and us. All of the directors who serve as members of the Audit Committee, Human Capital Management and Compensation Committee and the Nominating, Governance and Sustainability Committee are independent as required by the NYSE corporate governance rules. Under these rules, Audit Committee members also satisfy the separate SEC independence requirements, and the Human Capital Management and Compensation Committee members satisfy the additional NYSE independence requirements.

The Board of Directors has affirmatively determined that the following directors are independent:

Transactions Considered in Independence Determinations. In making its independence determinations, our Board of Directors considered transactions that occurred between us and entities associated with the independent directors and their immediate family members.

Mr. Sullivan is a director of SM Energy Company. SM Energy or its affiliates is a customer of TETRA, although Mr. Sullivan’s interest in these transactions was not considered to be material and therefore did not impact his independence. We have considered the foregoing and have concluded that these transactions and relationships did not disqualify Mr. Sullivan from being considered independent under the rules of the NYSE. Our Board of Directors has also determined that Mr. Sullivan does not have a material interest in these transactions and that he is independent.

Ms. McGee, through SDBM, provided consulting services to TETRA from August 11, 2021 to December 31, 2021 and earned $9,814 during the term of the agreement. We have considered the foregoing and have concluded that this relationship did not disqualify Ms. McGee from being considered independent under the rules of the NYSE. In addition, with respect to Ms. McGee’s service on the HCMCC, our Board of Directors determined that the consulting fees received by Ms. McGee prior to her appointment did not impair her independence from management or ability to make independent executive compensation judgments and determined that she is independent for board and all committee purposes.

Based upon his ongoing employment with us, the Board of Directors has determined that Mr. Murphy is not independent.

Board Leadership Structure; Separation of Positions of Chairman and Chief Executive Officer

As set forth in our Corporate Governance Guidelines, we require the separation of the positions of Chairman of the Board and Chief Executive Officer. Our Board of Directors believes that the separation of these positions strengthens the independence of our Board of Directors and its ability to carry out its roles and responsibilities on behalf of our stockholders. Our Chief Executive Officer is responsible for setting the strategic direction for TETRA and provides the day-to-day leadership of its operations and performance, while ~~Mr. Sullivan, as~~our Chairman provides overall leadership to our Board of Directors in its oversight function. AsOur Chairman ~~Mr. Sullivan~~ serves as the presiding director of executive sessions of the non-management and independent directors.

Our board is responsible for, and committed to, the oversight of the business of TETRA. In carrying out this responsibility, our board advises senior management, which is, in turn, responsible for the operations of our Company and driving long term value creation for our stockholders. Our board discusses and receives regular updates on a wide variety of matters affecting TETRA and the primary focus areas are business strategy, risk management, financial reporting and compliance, corporate governance and sustainability, ~~and~~ CEO performance, ~~and~~

executive succession ~~planning.~~planning, and diversity and inclusion. In many of these areas, significant responsibilities are delegated to the board’s committees, which are responsible for reporting to the board on their activities and actions. Please refer to “Board Role in Risk Oversight” for additional information on our committees.

It is our management’s responsibility to manage risks and to bring to the Board of Directors’ attention any aspects of our business or operations that may give rise to a material level of risk. Our Chief Executive Officer has ultimate responsibility for management of our business, including enterprise level risks and the risk management program and processes, and brings members of management from various business or administrative areas into meetings of the Board of Directors from time to time to make presentations and to provide insight to the board, including insight into areas of potential risk. Such risks include competition risks, industry risks, economic risks, credit and liquidity risks, risks from operations, risks posed by significant litigation and regulatory matters, cyber security risks, risks related to our compensation program and employee retention, and risks related to acquisitions and dispositions. The Board of Directors, either directly or through its committees, reviews with our management policies, strategic initiatives, and other actions designed to mitigate various types of risk.

Board Oversight of COVID-19 Impact and Company Responses. ~~As the COVID-19 pandemic has developed, the~~The Board has received frequent updates on the impact toof the COVID-19 pandemic on our employees, operations, and customers and reviewed with management the various measures taken to protect people’s health and maintain continuity of service for our customers. This Board oversight has included updates at board meetings held from mid-March 2020 through the filing of this Proxy Statement.

Corporate Governance

Enterprise Risk Management ~~Program~~. The board’s oversight of risk management is enhanced by the detailed information it receives as a result of our Enterprise Risk Management (“ERM”) program. Our ERM process is designed to identify potential key risks that may affect TETRA and manage risk within an established level of acceptable risk. The ERM assessment is performed quarterly and involves evaluation of key risk indicators. During the quarterly ERM assessment, management will review and, to the extent necessary, update or supplement a list of key risks affecting each respective business area along with the corresponding risk mitigation strategies. As part of the risk monitoring process, management evaluates each risk according to its likelihood of occurrence and, assuming that the development or event at risk was to occur, its most likely impact on our financial condition, operations, industry or reputation. The most significant risk items identified in each quarterly assessment are discussed with the Audit Committee. In addition, a complete copy of the ERM report is distributed to and discussed by the full board on an annual basis.

Cyber Security Risk Oversight. The board, with the assistance and support of the Audit Committee, oversees our management of cyber security risk. TETRA has taken a number of steps to manage and mitigate our cyber security risk, including entering into an information security risk insurance policy, establishing a dedicated IT security resource, engaging an independent firm to assess our security, improving our security posture, and rolling out continuing information security training to our employees. In addition, our IT organization has completed a ransomware incident response exercise and our management team has recently participated in a cyber incident response exercise conducted by an independent firm. At each quarterly meeting the Audit Committee receives an update from management regarding our cyber security risk profile and the board receives a cyber security report from management on an annual basis.

Human Capital Management Risk Oversight. We believe our efforts around human capital management add long-term value to our business and foster an inclusive culture for our employees. We have demonstrated a commitment to diversity through the people who guide our Company – starting at the top. Three of the seven director nominees (43% of our nominees) are women or racially diverse. Our board, Human Capital Management and Compensation Committee and our other committees play a role in the active oversight of our human capital management program. This is accomplished by focusing on these key areas: safety, talent development, inclusion and diversity, ethics and compliance, talent acquisition and retention, and compensation and benefits.

Our Human Capital Management and Compensation Committee receives a report at each meeting regarding the performance of our human capital initiatives compared to key performance indicators established by the committee and other human capital management matters, such as talent acquisition and retention, key employee compensation, talent development, and diversity and inclusion initiatives.

Our Audit Committee receives quarterly updates on our ethics and compliance program.

Our Nominating, Governance and Sustainability Committee ensures that we are seeking director candidates who will bring a diversity of background, experience, and viewpoints to our board.

Our Board receives quarterly updates regarding the performance of our HSE program

Our Board and Human Capital Management and Compensation Committee receive an annual update on succession plans for senior leadership.

S~~tock Ownership Guidelines~~

Our Board of Directors has adopted guidelines with regard to stock ownership for our directors and executive officers. The stock ownership guidelines are intended to align the interests of our directors and executive officers with the interests of our stockholders. Under the guidelines, our executive officers have historically been required to hold shares of our common stock with a value equal to a multiple, based upon position, of their base salary. ~~In addition to ownership of our stock, ownership of common units of our former subsidiary CSI Compressco LP by our executive officers and directors count under the guidelines.~~ For purposes of these guidelines: (1) each share of our common stock ~~and each CSI Compressco common~~or unvested restricted stock unit (“RSU”) owned on the date of our Annual Meeting each year is deemed to have a value equal to the greater of (a) the trading price as of the date the applicable share ~~or common unit~~ was acquired or (b) the trading price as of the date of our Annual Meeting. The guidelines establish the following minimum ownership:

Executive Officers:

Under the guidelines, newly appointed officers have five years from their date of appointment to meet the guidelines. In addition, in the event the multiple of an executive officer’s base salary is increased, the executive officer will have five years from the time of such increase to meet the new minimum.

As of the date of this Proxy Statement, subject to the transition periods described above, all covered officers are in compliance with the guidelines.

Non-Employee Directors - including the Chairman of the Board of Directors, are required to hold shares of our common stock ~~and/or common units of CSI Compressco~~ having a deemed value equal to five-times their annual cash retainer. Non-employee directors have four years from the date of their election or appointment to meet the guidelines. As of the date of this Proxy Statement, subject to the transition periods described above, all non-employee directors are in compliance with the guidelines.

	The Audit Committee’s primary purpose is to assist the Board of Directors in its oversight of:

	(iii)	the independent auditor’s qualifications;

	The Audit Committee has sole authority to appoint and terminate our independent auditors. To promote the independence of the audit, the Audit Committee consults separately with the independent auditors, the internal auditors, and management. As required by NYSE and SEC rules regarding audit committees, the Board of Directors has reviewed the qualifications of its Audit Committee and has determined that none of the current members of the Audit Committee has a relationship with us that might interfere with the exercise of their independence from us or our management, as independence is defined in the listing standards of the NYSE. Accordingly, our Board of Directors has determined that all current members of our Audit Committee are independent as defined in Section 10A of the Exchange Act and as defined in the listing standards of the NYSE. Further, our board has determined that Mr. Baldwin, the current Audit Committee chairman, is an “audit committee financial expert” within the definition established by the SEC.

~~Corporate Governance~~

Our Board of Directors has determined that each member of the HCMCC is independent, as independence is defined in the listing standards of the NYSE. The HCMCC may designate a subcommittee and delegate authority to such subcommittee as it deems appropriate.

Our equity compensation plans include provisions that enable the HCMCC to delegate its authority to approve certain grants of awards under those plans to a committee of our Board of Directors that may consist of one director. The Board of Directors previously established the Non-Executive Award Committee (the "NEA Committee"), which is a committee of one or more members of our Board of Directors. The NEA Committee is currently comprised of one member - Mr. Murphy. The HCMCC has delegated authority to the NEA Committee to make special inducement, merit, and retention awards, other than regular annual awards, to participants under those plans who are not subject to Section 16 of the Exchange Act and the rules and regulations promulgated thereunder, subject to certain limitations, including limitations on the number of awards that may be granted, as may be imposed from time-to-time by the HCMCC.

Compensation decisions for our Chief Executive Officer are made by the HCMCC. The HCMCC is also responsible for approving the compensation of our other executive officers and in such process, it reviews and gives significant consideration to the recommendations made by the Chief Executive Officer for such other executive officers. As part of its role in reviewing and approving such compensation, the HCMCC administers our equity compensation plan and our cash incentive plan under which cash incentive awards may be made to our executive officers and other key employees based on performance, including the attainment of performance goals. Our Chief Executive Officer, with input from senior management, recommends to the HCMCC base salaries, target cash incentive award levels, actual cash incentive award payouts, and equity awards, as well as company, division, and individual performance measures for our executive officers other than the Chief Executive Officer. The HCMCC considers, discusses, and takes action on such recommendations as it deems appropriate.

Independent Compensation Consultant. The HCMCC has the authority to retain, approve fees and other terms for, and terminate any compensation consultant, outside counsel, or other advisors to assist the committee in the discharge of its duties. In ~~2020,~~2021, the HCMCC has retained the services of Meridian Compensation Partners, LLC (“Meridian”), an independent provider of compensation consulting services, to review our compensation programs and practices and to assist in the review of compensation disclosures included in

this Proxy Statement. Meridian acted as independent advisor to the HCMCC and does not provide any other services to us or earn any compensation from us outside of the services provided as an independent advisor to the HCMCC.

Diversity. Although we have not adopted a separate policy with regard to the consideration of diversity when evaluating candidates for election to our board, our Corporate Governance Guidelines provide that when assessing candidates, we will consider diversity, including gender ~~diversity.~~and ethnicity. The Governance Committee believes that board membership should reflect diversity in the broadest sense, taking into account our needs and the current composition of the board. We strive to maintain a diversity of backgrounds and experience among the members of the board, as we believe this improves the quality of the board’s deliberations. The Board of Directors’ final selection of board nominees is based on merit, giving consideration to the nominee’s knowledge, experience, skills in areas deemed critical to understanding our business, and personal characteristics such as integrity and judgment, diversity, including gender diversity, ethnicity, and background, and the candidates’ other time commitments.

Board Evaluations – A Multistep Process

Our annual board and committee evaluations cover the following topics:

• Board and committee composition, including skills, background and experience;

• Review of key areas of focus for the board and effectiveness in overseeing these responsibilities;

• Satisfaction with board performance, including the performance of the board and committee chairs in those positions;

• Board and committee information needs and quality of materials presented;

• Areas where the board and committees should increase their focus;

• Satisfaction with the board schedule, agendas, time allotted for topics, and encouragement of open communication and discussion;

• Satisfaction with committee structure and responsibilities; and

• Access to management, experts, and internal and external resources

Our security holders and other interested parties may communicate with one or more of our directors (including the presiding director of executive sessions and the independent non-employee directors as a group) by mail sent to our Corporate Secretary, TETRA Technologies, Inc., 24955 Interstate 45 North, The Woodlands, Texas 77380, or by email at corpsecretary@tetratec.com. Such communications should specify the intended recipient or recipients. All such communications, other than commercial solicitations or communications, will be forwarded to the appropriate director or directors.

Director Nominations Submitted by Stockholders

The Nominating, Governance and Sustainability Committee will consider proposals for nominees for director from our stockholders. In order to nominate a director at the annual meeting, our bylaws require that a stockholder follow the procedures set forth in Article III, Section 3 of our Bylaws. (This Bylaw provision is available in the Corporate Governance section of the Investor Relations area of our website at www.tetratec.com.) In order to recommend a nominee for a director position, a stockholder must be a stockholder of record at the time the stockholder gives notice of the recommendation, and the stockholder must be entitled to vote for the election of directors at the meeting at which such nominee will be considered.

Stockholder recommendations must be made pursuant to written notice delivered to our Corporate Secretary at our principal executive offices no later than 80 days prior to the date of the annual or special meeting at which directors are to be elected; provided, that if the date of the annual or special meeting is not publicly announced more than 90 days prior to the annual or special meeting, such notice by the stockholder will be considered timely if delivered to the Corporate Secretary no later than the close of business on the tenth day following the day on which such announcement of the date of the meeting was communicated to the stockholders.

The stockholder notice must set forth the following:

name and address of the stockholder who intends to make the nomination and of the person or persons to be nominated;

a representation that the stockholder is a holder of record of common stock entitled to vote at the meeting and intends to appear in person or by proxy to nominate the person or persons specified;

Executive Su~~ccession~~Succession Planning

The Human Capital Management and Compensation Committee, the CEO, and the ~~Director~~Vice President of Human Resources evaluate, from time to time each year, executive development and succession planning to prepare us for future success. The succession planning process covers the CEO position as well as all senior management positions and certain other key positions. This review of executive talent determines readiness to take on additional leadership roles and identifies developmental opportunities needed to prepare our executives for greater responsibilities. Our short and long-term business strategy is considered when evaluating candidates and their skills. Where possible, our board gains insight through exposure to internal succession candidates from their presentations to the board, work with individual directors or board committees, and participation in board activities. The CEO makes a formal succession planning presentation to the Human Capital Management and Compensation Committee annually in conjunction with our annual strategy meeting in which our directors who are not members of the committee are invited to attend.

Insider Trading Policy (including Hedging Transactions)

We acknowledge that sales of our common stock by our executive officers will occur periodically. In particular, we believe that our executive officers who have a significant portion of their net worth in our common stock may desire to diversify their investment portfolios over time and may be required to sell our common stock to finance stock option exercises and to pay related taxes. We have established a policy for trading in our common stock. This policy is designed to help ensure compliance with federal securities laws and allow the anticipated periodic sales to occur in an orderly fashion.

Hedging Transactions. The trading policy also prohibits our directors, officers, and employees from engaging in short sales of our common stock, from buying or selling puts, calls or other derivative instruments involving our common stock, and from engaging in certain forms of hedging or monetization transactions involving our common stock. An exception to this prohibition may be granted where an officer, director or employee wishes to pledge our securities as collateral for a loan (not including margin debt) and clearly demonstrates the financial capacity to repay the loan without resort to the pledged securities. Any director, officer or employee who wishes to pledge our securities as collateral for a loan must submit a request for approval to our General Counsel at least two weeks prior to the proposed execution of documents evidencing the proposed pledge.

Certain Transactions

Related Person Transaction Policy. The Board of Directors, upon recommendation of the Audit Committee, has adopted the Policy and Procedures with respect to Related Person Transactions (the “Policy”), for the review and approval of certain related person transactions. The Policy covers transactions in which (i) we, or any subsidiary of ours, are a participant, (ii) the aggregate amount involved exceeds $100,000, and (iii) any related party (generally, directors and executive officers, and their immediate family members, and 5% stockholders) has a direct or indirect material interest. The Policy generally requires that such transactions be approved in advance by the Audit Committee. Under the Policy, the Audit Committee will consider all relevant facts and circumstances available to the committee and will approve such transactions only if they are in, or are not inconsistent with, our best interests and the best interests of our stockholders. In the event a transaction is not identified as a related person transaction in advance, it will be submitted to the Audit Committee, which will evaluate the transaction, including ratification or rescission of the transaction, and possible disciplinary action.

Transactions with Related Persons. Shawn L. Shoemake, the spouse of Alicia P. Boston, our General Counsel and Chief Compliance Officer, has been an employee of the Company since July 2009. Mr. Shoemake received total compensation of approximately $143,375 for his services for the year ended December 31, 2021.

Audit Committee Report

AUDIT COMMITTEE REPORT

The Audit Committee oversees our financial reporting, internal controls, and audit functions on behalf of the Board of Directors. Our management has the primary responsibility for preparing our financial statements in accordance with generally accepted accounting principles, maintaining effective internal control over financial reporting and assessing the effectiveness of our internal control over financial reporting. We have a full-time internal audit department that reports to the Audit Committee. This department is responsible for the evaluation of the adequacy and effectiveness of the organizations’ governance, risk management, and internal controls as well as carrying out assigned responsibilities to achieve the organizations’ stated goals and objectives.

Our independent registered public accountants, Grant Thornton LLP, or GT, are responsible for auditing our financial statements and internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States), or PCAOB, and issuing their reports based on that audit. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited consolidated financial statements for the year ended December 31, ~~2020~~2021 that are included in our Annual Report filed with the Securities and Exchange Commission with our management, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

Ernst & Young LLP was the Company’s independent registered public accounting firm for the years ended December 31, 2017, 2018, 2019, and the first quarter of 2020. On June 12, 2020, the Audit Committee approved the dismissal of Ernst & Young LLP (“Ernst & Young”) as our registered public accounting firm. On June 15, 2020, management notified Ernst & Young that it would be dismissed as our independent registered public accounting firm effective immediately. The audit reports of Ernst & Young on our consolidated financial statements as of and for the years ended December 31, 2019 and 2018 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2019 and 2018, and through June 12, 2020, there were no (a) disagreements (as that term is used in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which, if not resolved to the satisfaction of Ernst & Young, would have caused it to make reference to the subject matter in their reports; or (b) reportable events (as described in Item 304(a)(1)(v) of Regulation S-K). As reported in our ~~Change in Auditor~~ 8-K filed June 18, 2020, the Audit Committee selected GT to be the Company’s independent registered public accounting firm for the second, third and fourth quarters of 2020.

The Audit Committee is comprised of ~~four~~three non-employee independent directors and is governed by a written charter adopted by the Board of Directors that is reviewed by the committee annually and was last amended on December ~~18, 2019.~~13, 2021. The charter is available in the Corporate Governance section of the Investor Relations area of our website at www.tetratec.com. Under the charter, the primary function of the Audit Committee is to assist the Board in fulfilling its oversight responsibilities as to, among other duties: (1) the integrity of our financial statements, including a review of the application of accounting principles, significant financial reporting issues and judgments in connection with the preparation of the financial statements, and the effects of regulatory and accounting initiatives on the financial statements; (2) reviewing and discussing with management and our independent registered public accountants our earnings press releases, as well as public earnings guidance; (3) recommending to the board the filing of our audited financial statements with the Securities and Exchange Commission; (4) our disclosure controls and procedures and internal control over financial reporting, including review of any material issues as to the adequacy of internal control over financial reporting; (5) our compliance with legal and regulatory requirements and our Code of Business Conduct and Code of Ethics for Senior Financial Officers; (6) the performance of our internal audit function; (7) the performance of our compliance function; (8) our enterprise risk management process; (9) our information technology security and ~~(9)~~risk, including cybersecurity, and (10) the evaluation, appointment and retention of our independent registered public accountants, including a review of the firm's qualifications, services, independence, fees and performance.

In connection with the evaluation, appointment, compensation, retention and oversight of the independent registered public accountants, each year the Audit Committee reviews and evaluates the qualifications, performance and independence of the independent registered public accountants and lead audit partner, including taking into account the opinions of management and our internal auditor. In doing so, the Audit Committee

considers a number of factors including, but not limited to: quality of services provided; sufficiency of firm resources; technical expertise and knowledge of the industry; quality of communication and interaction with the firm; known significant legal or regulatory proceedings related to the firm; external data on audit quality and performance, including PCAOB reports; independence; objectivity; and professional skepticism. The Audit Committee also considers the advisability and potential impact of selecting a different independent registered public accounting firm.

~~Audit Committee Report~~

Further, the Audit Committee reviews in advance and pre-approves, specifically, audit and permissible non-audit services provided to us by GT. For more information regarding the Audit Committee’s preapproval procedures, please read “Audit Committee Preapproval Policies and Procedures” below.

The Audit Committee has also established procedures for the receipt, retention, and treatment, on a confidential basis, of any complaints related to accounting or compliance matters we receive. We encourage employees and third-party individuals and organizations to report concerns about our accounting controls, auditing matters, or anything else that appears to involve financial or other wrongdoing through one of the methods described in our Whistleblower Policy which is available in the Corporate Governance section of the Investor Relations area of our website at www.tetratec.com.

As discussed more fully in Proposal No. 2 on page 912 of the Proxy Statement, the Audit Committee and board believe that it is in the best interests of the Company and its stockholders to continue the retention of GT to serve as our independent registered public accountants. Accordingly, the Audit Committee has continued retention of GT as the Company’s independent auditor for ~~2021.~~2022. GT has been the independent auditor for the Company since June 2020. Although the Audit Committee has the sole authority to appoint the independent registered public accountants, the Audit Committee will continue to recommend that the board request the stockholders, at the Annual Meeting, to ratify the appointment of the independent registered public accountants.

The Board of Directors has determined that each member of the Audit Committee is independent and possesses the necessary level of financial literacy required to enable him or her to effectively serve as an Audit Committee member and that our Audit Committee Chairman qualifies as an Audit Committee Financial Expert. There were ~~eight~~five meetings of the Audit Committee during the year ended December 31, ~~2020.~~2021. The meetings of the Audit Committee are designed to facilitate and encourage communication among the members of the Audit Committee, management of the Company, our internal audit function, and GT.

In connection with the preparation of the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, ~~2020,~~2021, the Audit Committee discussed with the Company’s internal auditors and GT the overall scope and plan for their respective audits. The Audit Committee met with the internal auditors and GT, with and without management present, to discuss the results of their examinations, their evaluations of our internal controls, including internal control over financial reporting, critical audit matters addressed during the audit, and the overall quality of our financial reporting.

The Audit Committee reviewed with GT, which is responsible for expressing an opinion on the conformity of those audited consolidated financial statements with US generally accepted accounting principles, GT’s judgments as to the quality, not just the acceptability, of our accounting principles and such other matters as are required to be discussed with the committee by the applicable requirements of the PCAOB, including PCAOB Auditing Standard No. 16, Communications with Audit Committees, the rules of the SEC, and other applicable regulations. In addition, the Audit Committee has discussed with GT their independence from our management and the Company, including the matters contained in the letter from GT required by PCAOB Rule 3526, Communication with Audit Committees Concerning Independence, and considered the compatibility of non-audit services performed by GT with GT’s independence.

The Audit Committee also reviewed and discussed together with management and GT our audited consolidated financial statements for the year ended December 31, ~~2020,~~2021, and the results of management’s assessment of the effectiveness of our internal control over financial reporting and GT’s audit of internal control over financial reporting.

Over the course of a year, the Audit Committee has a rolling agenda covering a variety of standing matters such as briefings from the Internal Auditor on TETRA’s enterprise risk management program, it’s internal control system and on the outcomes of internal audits and notable control matters, briefings from the Chief Compliance Officer, tax matters, and information technology management and security. In 2021, in addition to the standing matters, members of management, the internal auditor, and the independent auditors also made presentations to the Audit Committee throughout the year on specific topics of interest, including (i) ~~smaller~~cyber security risk assessment and risk

The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions made by such member(s) to the entire Audit Committee at or before its next scheduled meeting. As of the date hereof, the Audit Committee has delegated this authority to the Chairman of the Audit Committee. Neither the Audit Committee, nor the person to whom pre-approval authority is delegated, may delegate to management their responsibilities to pre-approve services performed by the Audit Firm.

All requests or applications by the Audit Firm to provide services to us must be submitted to the Audit Committee or its chairman by both the Audit Firm and the Chief Financial Officer and must include a description of the services being requested for pre-approval and a joint statement as to whether, in their view, the request or application is consistent with applicable laws, rules, and regulations relating to auditor independence.

I. EXECUTIVE SUMMARY

Company Operations and Performance

We are ~~a geographically diversified global leader in onshore~~an industrial and oil & gas products and services company operating on six continents focused on bromine-based completion fluids, calcium chloride, water management ~~high-value completion fluids~~solutions, frac flowback and production well testing services. Calcium chloride is used in the oil and gas, industrial, ~~chemicals~~agricultural, road, food and beverage markets. We are evolving our business model by expanding into the low carbon energy markets with ~~new opportunities~~our chemistry expertise, key mineral acreage and global infrastructure. Recently announced initiatives include commercialization of TETRA PureFlow^® an ultra-pure zinc bromide for ~~low-carbon~~stationary batteries and energy ~~solutions. Prior~~storage; advancing an innovative carbon capture utilization and storage technology with CarbonFree to capture CO2 and mineralize emissions to make commercial, carbon-negative chemicals; and development of our lithium and bromine mineral acreage to meet the ~~closing~~growing demand for oil and gas products and energy storage.

In January of ~~the sale of the general partner interest~~2021, we divested our interests in CSI Compressco LP for over $30 million of cash proceeds, simplifying our capital structure and unlocking significant stockholder value, and announced several initiatives to leverage our chemistry expertise and resources around carbon capture and energy storage. These initiatives reflect our continued focus on ~~January 29, 2021 (the “GP Sale”), TETRA owned all of~~sustainability and the ~~general partner interest in CSI Compressco LP (“CCLP”), a master limited partnership that provides compression services~~environment, and ~~equipment for natural~~present growth opportunities beyond our historic oil, gas, and ~~oil production, gathering, artificial lift, transmission, processing~~industrial applications. By the end of 2021, our two ongoing business segments, Completion Fluids & Products and ~~storage.~~Water & Flowback Services, were rapidly approaching pre-pandemic performance levels well ahead of pre-pandemic industry activity levels.

COMPENSATION DISCUSSION & ANALYSIS

The onset of the global COVID-19 pandemic and subsequent drop in energy prices during the first quarter of 2020 caused an immediate reduction in demand for our products and services. In response, we actively managed our flexible cost structure by implementing temporary and permanent cost reductions, including reduced capital expenditures, workforce reductions, salary reductions, and suspension of matching contributions under our 401(k) Plan. As a result of these quick and decisive cost reduction actions, we decreased operating cost (as it impacts adjusted EBITDA) by $168 million compared to 2019, we increased adjusted free cash flow from continuing operations by $81 million in 2020, relative to 2019, and we reduced net debt by $57 million as of December 31, 2020.

In addition, in January of 2021 our long-term strategic plan with regard to our compression business came to fruition with the sale of our general partner interest in CCLP. This transaction allows us to focus on the capital efficient business model that has continued to generate positive free cash flow even through one of the worst downturns the energy industry has experienced, due to COVID-19.

~~Despite very challenging conditions during 2020, we maintained our commitment to safety and service quality for our customers and generated positive free cash flow in all four quarters of the year.~~

~~Actions taken by the Committee during 2020 to strategically design compensation programs that retain valued executive talent and reward the creation of stockholder value are further described below.~~

Positive ~~2020~~2021 Say-on-Pay Vote Outcome and Stockholder Engagement ~~with Our Stockholders~~

In ~~2020,~~2021, we received approximately ~~90%~~96% stockholder support on our say-on-pay advisory vote. We maintain an ongoing, proactive outreach effort with our stockholders. ~~In addition to financial and operations-related outreach by our executives and investor relations team to investors throughout the year, our~~Our board has a practice of periodically engaging with stockholders to seek feedback on our executive compensation ~~program~~program. We appreciate that our stockholders take the time to have a candid dialog with us and provide us with meaningful feedback. Although each stockholder’s particular focus is slightly different, our pay for performance approach to executive compensation, emphasis on social responsibility, and human capital management have been well received. The feedback we receive from future stockholder outreach efforts will be considered in our assessment of any changes in our compensation programs. We are pleased with our say-on-pay results and stockholder feedback and will continue to engage with our stockholders to be sure we understand their perspectives.

We appreciate that our stockholders take the time to have a candid dialog with us and provide us with meaningful feedback. Although each stockholder’s particular focus is slightly different, our pay for performance approach to executive compensation, emphasis on corporate governance and social responsibility, and long-term strategy have been well received. The feedback we receive from future stockholder outreach efforts will be considered in our assessment of any future changes in our compensation programs. We are pleased with our say-on-pay results and stockholder feedback and will continue to engage with our stockholders to be sure we understand their perspectives.

Overall Compensation Structure

We seek to structure a balance between achieving positive short-term annual results and ensuring long- term viability and success by providing both annual and long-term incentive opportunities. The following graphic illustrates the components of the total compensation opportunities available to members of our Senior Management:

Alignment of Pay with Stock Price Performance

A significant portion of our NEOs’ total compensation is in the form of long-term incentive awards that are tied to the long-term performance of our stock and certain key measures that drive stockholder returns. The process by which the Committee determines the structure of our NEOs’ long-term incentive awards takes into account TETRA’s stock price performance, ~~and~~ its financial performance relative to our peers and internal budgeted expectations, market compensation and the need to retain executive talent over the long-term, and alignment with the returns generated for our stockholders.

To demonstrate this tie to performance, the table below explains the differences between Total Direct Compensation as presented in the Summary Compensation Table, Target Total Direct Compensation as approved by the Committee (that is, the total compensation opportunity), and Realized Compensation (that is, the value of compensation as of December 31 of a given year, which reflects the performance level of our CEO, Mr. Murphy). The table and accompanying graph represent supplemental information that is not intended to be a substitute for the information provided in the Summary Compensation Table on page ~~68,~~59, which has been prepared in accordance with the SEC’s disclosure rules.

II. COMPENSATION PHILOSOPHY & OBJECTIVES

Overview of Compensation Philosophy and Objectives

We strive to maintain a compensation program that is competitive in the labor markets in which we operate. Our philosophy is to maintain an executive compensation program that will attract, retain, motivate, reward, and align highly qualified and talented individuals to enable us to perform better than our competitors. The following are our key objectives in setting the compensation programs for our Senior Management:

Attract	Retain	Motivate	Reward	Align
Structure pay programs and compensation levels that reflect competitive market practices in relevant markets, taking into consideration pay practices of our relevant peer group.	Provide long-term equity and cash compensation opportunities that are consistent with our overall compensation philosophy and drive individual and organizational performance.	Motivate Senior Management to deliver outstanding financial and operational results by establishing performance objectives that incentivize exceptional individual and team effort.	Provide a significant percentage of total compensation that is “at-risk” or “variable,” based on achievable performance measures that are challenging and meaningful to our long-term strategic goals.	Ensure that a significant portion of total compensation is determined by increases in stockholder value, thus assuring alignment of Senior Management and our stockholders’ interests.

Focus on Performance-Based Pay

In establishing target compensation levels, the Committee places a significant portion of our NEOs’ compensation “at-risk” through the use of variable compensation, much of which is performance-based. Historically, variable pay has included the following:

Annual Cash
Incentive

Long-Term Cash
Incentive

Restricted Stock/
RSUs

~~Phantom Units~~

~~Performance-based cash incentives based on achievement of specific annual performance objectives.~~

~~Performance-based long-term cash based on achievement of specific long-term financial and other performance objectives.~~

~~Shares of TETRA restricted stock or restricted stock units (RSUs) that vest over time and have value based on the price of TETRA stock at the time of vesting.~~

~~CCLP units that vest over time and create value based on the price of CCLP common units at the time of vesting.~~

Annual Cash Incentive. Performance-based cash incentives based on achievement of specific annual performance objectives.

Long-term Cash Incentive. Performance-based long-term cash based on achievement of specific long-term financial and other performance objectives. Awards of long-term performance-based cash provide the same retention value as awards of long-term equity and allow us to conserve stockholder approved awards under our equity plans.

RSUs. Shares of TETRA restricted stock units (RSUs) that vest over time and have value based on the market price of TETRA stock at the time of vesting.

Phantom Units. Prior to our divestiture of CSI Compressco in January of 2021, CCLP units that vest over time and create value based on the price of CCLP common units at the time of vesting.

~~As further discussed below, beginning~~Beginning in 2020, based in part on feedback from our stockholders, we ~~have~~ revised the structure of our long-term incentive awards to provide more direct emphasis on financial performance metrics that incentivize Senior Management to focus on creation of long-term, sustainable stockholder value.

In addition, ~~for~~beginning with the long-term performance-based cash awards granted in 2020, ~~for the January 1, 2020 through December 31, 2022 performance period,~~ a cap of 100% of the target award amount ~~will be~~is imposed on any payment of awards based on relative TSR if our absolute TSR over the 3-year performance period is negative.

III. ROLES & PROCESSES

Role of Committee. The Committee determines our overall compensation philosophy, sets the compensation of our CEO, approves the compensation of our NEOs, and oversees the compensation of the other members of Senior Management. In making compensation decisions, the Committee considers all of the following factors:

our financial and operational results;

our strategic goals and accomplishments;

alignment of compensation opportunities with the interests of our stockholders;

the performance and potential of our CEO and other members of Senior Management;

compensation paid by companies in our compensation peer group;

compensation data from available industry surveysof~~theoilfieldservicesindustry~~ for executive officers with similar positions and with roles and responsibilities similar to our Senior Management;

market data and analysis and recommendations provided by any compensation consultant engaged by the Committee;

•

~~overallcompensationpaid~~to~~ourCEOandmembers~~of~~SeniorManagement~~in~~previousyears,including the value of equity-basedcompensation;~~

the recommendations of our CEO with respect to specific compensation matters, including changes in compensation for our Senior Management;

the retention value of long-term compensation plans;

alignment of our overall compensation program with our policies and strategies related to human capital management, including diversity, equity, and inclusion; and

exogenous macroeconomic factors such as the COVID-19 pandemic.

The Committee has the authority to retain compensation consultants, outside counsel, or other advisors to assist the Committee in the discharge of its duties. In any given year, the Committee bases its decision on whether to retain a compensation consultant on factors including prevailing market conditions, regulatory changes governing executive compensation, and the quality of any other relevant data that may be available. If a compensation consultant is engaged, the Chairman of the Committee maintains a direct line of communication with the consultant and arranges meetings with the consultant that may include other members of the Committee and/or the CEO and certain members of Senior Management. The Committee, and/or its Chairman, also periodically meets with the compensation consultant independently of management. Through this communication with the Chairman of the Committee, the consultant reports to, and acts at the direction of, the Committee. Although our CEO and certain members of Senior Management may receive the consultant’s reports and data, the Committee retains and exercises sole control and authority over the compensation consultant.

Role of CEO. Our CEO makes recommendations to the Committee with regard to salary, including any adjustments, and the annual and long-term incentives available to our Senior Management, excluding himself. His recommendations are based on factors such as his judgment and experience, available market data, and his evaluation of individual performance and contribution. In the Committee’s review of the changes in compensation recommended by the CEO, the Committee considers the CEO’s evaluations of and recommendations for each member of Senior Management as well as its own evaluations of Senior Management and the input and analysis of the Committee’s compensation consultant. In conjunction with our CEO, the Committee reviews the compensation of our Senior Management other than our CEO. Subsequently, the Committee, in executive session, establishes the compensation for our CEO.

COMPENSATION DISCUSSION & ANALYSIS

Role of Compensation Consultant. In August of 2019, the Committee retained the services of Meridian Compensation Partners (“Meridian”), a provider of executive compensation consulting and corporate governance services to over 700 major publicly traded and privately held corporations. Before engaging Meridian, the Committee confirmed that Meridian did not have business or personal relationship with any of our executive officers or any member of the Committee, and that Meridian had procedures in place to prevent conflicts of interest. The Committee discussed these considerations and concluded that there were no conflicts of interest with respect to the compensation consulting services provided by Meridian. The Committee continues to consider these matters, as they relate to Meridian, on an ongoing basis.

Peer Groups

In order to ensure the competitiveness of our compensation program, which is a critical factor in our ability to attract and retain high-caliber executive talent, the Committee periodically reviews compensation paid by other companies in the oilfield services industry. For ~~2020,~~2021, the Committee, with the assistance of Meridian, adopted ~~separate~~one peer ~~groups~~group for both our evaluation of Senior Management compensation ~~(our “compensation peer group”)~~ and our relative TSR performance measure under our long-term incentive ~~awards (our “performance peer group”). Each~~awards. The peer group is reviewed by the Committee on an annual basis to ensure that we maintain appropriate ~~groups of~~ comparator companies.

In some years, the compensation peer group is used to determine market levels of the main elements of executive compensation: base salary, annual incentives, and long-term incentives. The compensation peer group is also used to gauge industry practices regarding the structure and mechanics of annual and long-term incentive plans. Criteria for selecting companies to be included in the ~~compensation~~ peer group include competition with us in terms of the customers we serve, our belief that we compete with them for talent, overall comparability in terms of size (revenue and market cap), and comparable geographic areas of operation.

~~COMPENSATION DISCUSSION & ANALYSIS~~

In ~~December~~November of ~~2019,~~2020, based on Meridian’s recommendation, the Committee adopted the following ~~compensation~~ peer group to be used for the purpose of making appropriate peer comparisons for the Committee’s evaluation of our ~~2019~~2021 compensation program and determination of changes to be made in ~~2020. Subsequent~~2021, and to measure our relative total stockholder return (“RTSR”) under our long-term cash incentive awards to be granted during 2021. Following the adoption of this peer group, the Committee determined that there would be noonly limited adjustments to ~~2020~~2021 executive compensation, ~~(outside of adjustments in connection with changes in responsibility),~~ and they did not review specific elements of compensation paid to the peer group:

Compensation & Performance Peer Group

Used to evaluate the

• ~~Oil States International,~~Patterson-UTI Energy, Inc.

• Precision Drilling Corp.

• RPC Inc.

• Select Energy Services, Inc.

• USA Compression Partners LP

Also in December of 2019, with the assistance of Meridian, the Committee developed a performance peer group to measure our relative total stockholder return (“RTSR”) under our long-term cash incentive awards. The performance peer group is comprised of companies that directly compete with us in terms of one or more of the products and services we offer or the customers we serve. The following performance peer group was adopted by the Committee in December of 2019 in anticipation of their approval of the long-term cash incentive compensation awards for the performance period of January 1, 2020 through December 31, 2022:

~~Performance Peer Group~~

Used to evaluate our
RTSR under performance-based long-term cash

• ~~CES Energy Solutions Corp.~~

• ~~Dril-Quip, Inc.~~

• ~~Natural Gas Services Group~~

• ~~Newpark Resources, Inc.~~

• ~~Oil States International, Inc.~~

• ~~Select Energy Services, Inc.~~

• ~~Solaris Oilfield Infrastructure~~

• ~~USA Compression Partners LP~~

The Role of Market Data. ~~In certain years,~~While the Committee does consider our ~~Committee’s~~peer group’s practices in establishing compensation ~~consultant uses~~opportunities, it does not specifically benchmark the values of base salaries, annual incentives, or long-term incentives relative to that peer group or any survey data. Rather, the Committee periodically reviews the overall compensation ~~data gathered from~~offered by the members of our peer group in order to ensure that our compensation peer group as well as supplemental data from market surveys to benchmark our Senior Management compensation. Our review of this data typically focuses on the main elements of Senior Management compensation: base salary, annual incentive cash award opportunity, long-term compensation, and total direct compensation.program remains competitive. Although we review both target compensation and actual compensation paid, our focus is on target compensation, including the target amount of annual ~~cash~~and long-term award opportunities, as it provides the best indication of competitive compensation levels for our Senior Management.

The market data is also used to gauge industry practices regarding the structure and mechanics of annual and long-term incentive plans.

We strongly believe that Senior Management should be compensated with a package that includes the following four elements:

Element	Purpose	Key Features	Changes for ~~2020~~2021
Base ~~Salary~~salary	Fixed base pay to competitively compensate executives for their roles at TETRA	• The Committee periodically reviews relevant market data to ensure our salary program is competitive • Salary may be adjusted for performance, expansion of duties and responsibility, and changes in market salary levels • When considering salary adjustments, the Committee reviews corporate performance goals, individual performance and potential, and our CEO’s specific compensation recommendations (except with regard to his own salary) •With the exception of one base salary increase related to an expansion of duties, none of our NEOs received base salary adjustments during 2020 prior to the 20% reduction that took effect in April 2020	• ~~In April 2020, in response to decreased demand~~Base salaries for our ~~products~~CEO and ~~services driven by the pandemic, base pay for each~~CFO were reinstated to 90% of ~~our NEO’s was reduced by 20%~~ •~~The 20% reductions remain~~pre-pandemic levels in ~~effect~~July 2021 in connection with 25% increases in their annual cash incentive targets

Base Salary


5648 I TETRA Technologies, Inc.		~~2021~~2022 Proxy Statement

COMPENSATION DISCUSSION & ANALYSIS

~~Base Salary~~

In December of 2019 the Committee determined that our NEOs and Senior Management would not receive base pay adjustments during 2020, other than adjustments related to expansion of duties. On April 1, 2020, Mr. Moeller, who had held the position of VP Global Supply Chain since 2018, was promoted to the position of Sr. Vice President. In connection with this promotion, Mr. Moeller received a 10% increase in base pay.

The onset of the global COVID-19 pandemic and subsequent drop in energy prices during the first quarter of 2020 caused an immediate reduction in demand for our products and services. In response, we actively managed our flexible cost structure by implementing temporary and permanent cost reductions, including reduced capital expenditures, workforce reductions, salary reductions, and suspension of matching contributions under our 401(k) plan. Effective April 11, 2020, the base pay of each of our NEOs was reduced by 20%. ~~Due~~Effective July 31, 2021, in light of increased commodity prices and improved activity levels, base salaries for Messrs. Murphy and Serrano were partially reinstated to 90% of 2020 pre-pandemic levels, and base salaries for each of our other NEOs were fully reinstated to 100% of 2020 pre-pandemic levels. Also effective on July 31, 2021, the ~~continued uncertainty surrounding~~Committee increased Mr. Moeller’s base salary by 15.2% in consideration of his new responsibilities managing our carbon capture and energy storage initiatives.

The table below shows the ~~timing and conditions under which the economy will return to a more normal activity level and result~~partially- or fully-reinstated base salary for each of our NEOs as of July 31, 2021 that are still in ~~an increase in demand for energy,~~effect as of the date of this Proxy Statement, including the ~~base salaries of our NEOs have not been returned to the unreduced amounts shown in the table below.~~adjustment noted above for Mr. Moeller.

(1) In connection with Mr. Wallace retiring from his positions as Sr. Vice President and General Counsel on July 27, 2020, his annual base pay was reduced to $192,500 as of that date. Mr. Wallace remains employed by us in a non-executive position.

Annual Cash Incentives

~~As part~~In July of ~~its annual review of Senior Management compensation~~2021, in ~~December,~~connection with the salary adjustments discussed above, the Committee ~~reviews~~increased the annual performance-based cash incentive targets for our CEO and CFO, placing a ~~preliminary estimate~~larger portion of ~~the aggregate amount of~~their target total direct compensation at risk. Specifically, Mr. Murphy’s annual cash incentive ~~compensation~~target was increased from 100% of his annual base salary to ~~be awarded under our Cash Incentive Compensation Plan (CICP) based on the current year’s performance~~125% of his annual base salary, and ~~discusses the overall effectiveness~~Mr. Serrano’s annual cash incentive target was increased from 80% of ~~the plan in furthering our compensation~~ ~~philosophy.~~his annual base salary to 100% of his annual base salary.

The following table sets forth the ~~original~~annual cash award opportunities for the ~~2020~~2021 plan year, shown as a percentage of annual base salary, for our CEO and each of our other NEOs. As an example, as shown below, Mr. Murphy’s target award opportunity is ~~100%~~125% of his base salary; therefore, his threshold award opportunity, which is 30% of his target award opportunity, is ~~30%~~37.5% of his base salary. No amounts may be earned below the threshold percentage of base salary for any performance measure, and award opportunities are capped at the over-achievement percentage of base salary level for the NEOs shown in the table below. The target annual cash incentive opportunity for each NEO is based on his final 2021 base salary, as shown in the last column of the table above under “Base Salary.”

	Threshold % of Base Salary (30% of Target Award)	Target Award as % of Base Salary	Stretch % of Base Salary (150% of Target Award)	Over-Achievement % of Base Salary (200% of Target Award)	Threshold % of Base Salary (30% of Target Award)	Target Award as % of Base Salary	Stretch % of Base Salary (150% of Target Award)	Over-Achievement % of Base Salary (200% of Target Award)

COMPENSATION DISCUSSION & ANALYSIS

Performance Measure	Target Performance Objective	Business Consideration
~~Average~~Aggregate Division Adjusted EBITDA	(Determined based on ~~an average~~the sum of Division Adjusted EBITDA ~~results.~~results, adjusted to include an allocation of Corporate EBITDA)	$53.0 million at target (applicable to Messrs. Murphy and Serrano)	The ~~Average~~Aggregate Division Adjusted EBITDA performance measure applies only to Corporate participants and ensures focus on the financial outcome of day-to-day and long-term operating decisions that impact the overall profitability of our businesses, including: • Ensuring that day-to-day spending is tightly managed and aligned with our annual operating budget, and that operational plans and projects (including acquisitions) are quickly integrated in order to maximize efficiencies. • Prioritizing projects across the organization to elevate focus on those that have the greatest potential return on investment. • Driving cross-functional alignment among product lines and geographies to capture incremental improvements in productivity.
~~Corporate G&A Cost Control~~	~~Determined based on a percentage of actual 2020 revenue.~~	The Corporate G&A Cost Control performance measure provides an incentive for Corporate employees to closely manage controllable expenditures such as the use of contractors, office supplies, travel and related expenses, and subscriptions and memberships.
Division Adjusted EBITDA for: Completion Fluids & Products, and Water & Flowback Services	Completion Fluids & Products: $65.2 million at target Water & Flowback Services: $15.3 million at target (the sum of the two targets is applicable to Messrs. Sanderson and Mucha, the Completion Fluids & Products target is applicable to Mr. ~~Sanderson: $55.6 million~~ ~~Mr. Moeller: $39.6 million~~Moeller)	~~Senior Management~~Our NEOs impact line-of-sight Division Adjusted EBITDA by: • Ensuring differentiation of service quality and depth of service, which position us to manage pricing through market cycles and pursue and maintain relationships with the most profitable customers. • Driving reductions in our cost to deliver services, through robust cost controls, automation, and new technologies. • Managing external relationships, including strong marketing efforts to spearhead our introduction to new geographies and customers. • Fostering innovation to develop new products and technologies that expand our customer base. • Supporting integration of our service offerings, to broaden the scope of products and services we offer to new and existing customers.
Individual Performance Objectives (“IPOs”)		IPOs provide an opportunity for each NEO to earn incentive compensation based on their personal or team performance compared to established target objectives ~~approved~~reviewed by the Committee at the beginning of the plan year. We believe that IPOs are a critical component of the plan structure, as they drive performance related to specific strategic objectives and line-of-sight goals.

~~Following~~Under the ~~Committee’s approval of these~~annual incentive awards for 2021, safety is a negative modifier that may reduce payments earned under other performance metrics if trailing and leading indicators are not attained. In addition, actual results for the Aggregate Division Adjusted EBITDA and Division Adjusted EBITDA performance measures ~~and~~had to reach a minimum threshold level of 70% of the established target performance objectives shown in the table below for ~~the 2020 plan year, the sudden onset~~any portion of the ~~global COVID-19 pandemic~~awards based on those measures to be earned. A threshold payment level of 30% corresponds to the threshold performance level of 70% for each such performance objective and ~~subsequent drop in energy prices created~~ a ~~large degree~~maximum payment level of ~~uncertainty regarding our ability~~150% corresponds to ~~attain~~the maximum performance level of 125% for each such performance objective. For actual results that fall between threshold and maximum, straight line interpolation is used to determine the earned amount of the award. For results that exceed 125% of an established target performance objective, an over-achievement payment of up to 200% of an individual’s target award may be allocated by the Committee on a discretionary basis.

The following table shows the target performance ~~objectives established under~~objective and actual 2021 result for each performance measure applicable to our NEOs, as well as the ~~CICP. The Committee considered these factors~~IPOs that were reviewed and ~~elected not to adjust the performance measures and target performance objectives that had previously been established under the 2020 CICP.~~

~~In February 2021,~~approved by the Committee ~~determined that we did not attain the minimum adjusted EBITDA results required under the 2020 CICP across all~~for each of our ~~businesses; however,~~NEOs for the Committee considered that we maintained positive cash flow throughout 2020, which surpasses results reported by many of our peers in the industry. Accordingly, the Committee approved payment of a discretionary bonus for 2020 to Mr. O’Brien, who did not receive a performance-based incentive award discussed below. Messrs. Murphy, Serrano, Sanderson, and Moeller did not receive discretionary bonuses for 2020. 2021 plan year.

52 I TETRA Technologies, Inc.		2022 Proxy Statement

COMPENSATION DISCUSSION & ANALYSIS

The Committee has historically approved awards of long-term incentives on an annual basis, in February of each calendar year, following their review of prior calendar year performance. The Committee approved annual awards of TETRA ~~restricted stock units~~RSUs under the TETRA First Amended and Restated 2018 Equity Incentive ~~Compensation~~ Plan (the “2018 Plan”) to each of our NEOs on February ~~20, 2020.~~17, 2021. One-third of the ~~restricted stock units~~RSUs vested on the first anniversary of the grant date, and a one-sixth portion of the ~~restricted stock units~~RSUs will vest every six months ~~thereafter.~~ until fully vested.

Also on February 20, 2020, the Committee recommended to the board of directors of the general partner of CCLP, CSI Compressco GP Inc. (the “CCGP Board”), approval of awards of CCLP phantom units to each of our NEOs except Mr. Sanderson, who does not have significant responsibility for the operations of CCLP. The CCGP Board approved such awards on February 22, 2020. In connection with the GP Sale in January17, 2021, ~~the CCGP Board accelerated the vesting of CCLP phantom unit awards granted in 2020.~~

~~Also in February 2020,~~ the Committee established performance measures and performance objectives applicable to the long-term, performance-based cash portions of the LTI awards granted to our NEOs. Such awards were granted under the ~~Cash Incentive Compensation Plan~~CICP for the three-year performance period ending on December 31, ~~2022.~~2023. The performance measures and the relative weights of each such performance measure for these long-term cash incentive awards are:

TETRA's RONCE (EBIT) for each year in the three-year period ending December 31, ~~2022,~~2023, weighted 50%; and

total stockholder return relative to our ~~performance~~ peer group for the three-year period ending December 31, ~~2022,~~2023, weighted 50%.

For these ~~2020~~2021 long-term cash awards, the Committee determined to utilize the RONCE (EBIT) performance measure in ~~place of cash from operations performance measure utilized in 2019 in~~ order to focus orour NEOs and Senior Management on creation of sustainable stockholder value.

In addition, a cap of 100% of the target award amount will be imposed on the 50% portion of the long-term cash awards based on relative TSR if our absolute TSR over the ~~3-year~~three-year performance period is negative. The Committee believes that this provision promotes better alignment with the financial outcomes experienced by our long-term stockholders.

On an annual basis, with the assistance of its compensation consultant, the Committee develops a ~~performance~~ peer group that is used ~~only~~ to measure our RTSR under our long-term cash incentive awards. The ~~performance~~ peer group is comprised of companies that directly compete with us in terms of one or more of the products and services we offer or the customers and geographies we serve. The following ~~performance~~ peer group was adopted by the Committee in ~~December~~November of ~~2019~~2020 in anticipation of their approval of the long-term cash incentive compensation awards for the performance period of January 1, ~~2020~~2021 through December 31, ~~2022:~~2023:

For each performance measure, the following performance objectives and payment levels have been established by the Committee. If actual results fall between these established performance levels, straight line interpolation will be used to determine earned amounts of the awards:

For TETRA's RONCE (EBIT), the threshold performance level is 80% of the target performance objective and corresponds to a 30% payment level; no portion of the award may be earned for results below the threshold performance level. The stretch performance level is 125% of the target performance objective and corresponds to a 150% payment level, and the over-achievement performance level is 150% of the target performance objective and corresponds to a 200% payment level.

For total stockholder return relative to our peer group for the three-year period ending December 31, 2023, the threshold performance level is 50% of the target performance objective and corresponds to a 0% payment level; no portion of the award may be earned for results below the threshold performance level. The stretch performance level is 150% of the target performance objective and corresponds to a 200% payment level.

In addition, in May of 2019 upon Mr. Murphy’s promotion to the position of Chief Executive Officer, the Committee established a performance measure and performance objectives applicable to a long-term cash incentive award for the three-year performance period ending December 31, 2021. The sole performance measure for this long-term cash incentive award was RONCE (EBIT), determined on an annual basis, with payment of any earned amounts deferred until March of 2022. Our RONCE (EBIT) performance measure is defined as earnings before interest and tax (EBIT), divided by the average of current year and last year net capital employed. Net capital employed is defined as total assets minus cash, minus current liabilities, plus current debt. The Committee utilized the RONCE (EBIT) performance measure for this long-term incentive award in order to focus our then incoming CEO on the creation of sustainable stockholder value. Please refer to Appendix A in this Proxy Statement for reconciliations of non-GAAP financial measures.

Based on an analysis of our results for the performance period ended December 31, ~~2020,~~2021, the Committee determined that our total stockholder return placed us at the ~~34.6~~96.7^th percentile of the applicable peer group, ~~between~~above the ~~threshold and target~~stretch performance ~~levels.

In addition, our ~~total stockholder return~~absolute TSR for the ~~performance~~ period was ~~negative,~~52.9%, and we were one of only two companies in our peer group to achieve a positive TSR for the period of January 1, 2019 through December 31, 2021.

Payments Earned Under 2020 Performance Awards

~~The~~

During 2020, the sudden onset of the global COVID-19 pandemic and subsequent drop in energy prices created a need to review and refocus the target performance objectives established under our ~~2020 Cash Incentive Compensation Plan (our “2020 CICP”).~~CICP for 2020. Considering this uncertainty and acknowledging our particular need to retain key employees critical to the long-term success of our businesses, the Committee approved time- and performance-based incentive awards (“Performance Awards”) for certain NEOs, that ~~may~~would be settled at the end of the performance period in ~~cash, stock, or~~ a combination of cash and stock. Messrs. Murphy, Serrano, Sanderson, and Moeller were each granted a Performance Award. Mr. O’Brien, who received a discretionary bonus for 2020, and Mr. Wallace, who retired from his positions as Sr. Vice President and General Counsel during 2020, did not receive a Performance Award.

In determining the structure and maximum award opportunities available under the Performance Awards, the Committee gave significant weight to the following factors:

The base salary of each of our NEOs had been reduced by 20%.

Annual awards under our CICP for 2020 ~~CICP~~ were not expected to be ~~earned.~~earned (and in fact, none of the NEOs who received a 2020 Performance Award earned any portion of their CICP award for 2020).

The market for executive management talent was very competitive with a number of companies emerging from bankruptcies with strong balance sheets and looking for new leadership.

The maximum value of each Performance Award iswas equal to 100% of each ~~applicable~~ NEOs’ unreduced annual base salary for 2020 (“Unreduced Salary”).

The Performance Awards were comprised of the following four components:


	□ Component One Time-Based Amount

Retirement, Health, and WelfareBenefits

We offer a variety of health and welfare benefits to all eligible employees. Members of Senior Management are generally eligible for the same benefit programs on the same basis as the broad-base of our employees. Our health and welfare programs are intended to protect employees against catastrophic loss and to encourage a healthy lifestyle. These health and welfare programs include medical, wellness, pharmacy, dental, life insurance, short-term and long-term disability insurance, and insurance against accidental death and disability.

401(k) Plan. We offer a 401(k) program that is intended to supplement a participant’s personal savings and social security benefits. Under our 401(k) Retirement Plan (the “401(k) Plan”), eligible employees may contribute on a pretax basis up to 70% of their compensation, subject to an annual maximum dollar amount established under the Code. We generally make a matching contribution under the 401(k) Plan equal to 50% of the first 8% of annual compensation the participant contributes to the 401(k) Plan. InMatching contributions under the 401(k) Plan were suspended from April of 2020 through October of 2021 in connection with cost reduction actions taken in response to the global COVID-19 ~~pandemic, matching contributions under the 401(k) Plan were suspended.~~pandemic. As of December 31, ~~2020,~~2021, approximately ~~86%~~88% of all eligible employees were participating in the 401(k) Plan. All employees (other than nonresident aliens) who have reached the age of


58 I TETRA Technologies, Inc.		2022 Proxy Statement

COMPENSATION DISCUSSION & ANALYSIS

eighteen are eligible to participate in the 401(K) Plan beginning on the first day of the month following their completion of 30 days of service with us.

Nonqualified Deferred Compensation Plan. We provide our Senior Management, directors, and certain other key employees with the opportunity to participate in the Executive Nonqualified Excess Plan, an unfunded, deferred compensation program. There were 1613 participants in the program at December 31, ~~2020.~~2021 (none of our current NEOs participate in this plan). Under the program, participants may defer a specified portion of their annual total cash compensation, including salary and performance-based cash incentive compensation, subject to certain established minimums. The amounts deferred may increase or decrease depending on the deemed investment elections selected by the participant from among various hypothetical investment election options. Deferral contributions and earnings credited to such contributions are 100% vested and may be distributed in cash at a time selected by the participant and irrevocably designated on the participant’s deferral form. In-service distributions may not be withdrawn until two years following the participant’s initial enrollment. Notwithstanding the participant’s deferral election, the participant will receive distribution of his deferral account if the participant becomes disabled or dies, or upon a change in control.

Perquisites

Perquisites (“perks”) are not a material component of our executive compensation. In general, NEOs are not compensated for and do not receive reimbursements for ~~the private use of country clubs,~~ meals, airline and travel costs other than those costs allowed for all employees, or for tickets to sporting events or entertainment events, unless such tickets are used for business purposes. Further, our NEOs do not receive compensation or reimbursements for hunting and fishing camp costs or home security expenses. During ~~2020,~~2021, no NEO received any compensation for or reimbursement of any of the foregoing costs or expenses incurred for non-business purposes.

Clawback Policy

In 2018, the Committee adopted the Executive Incentive Compensation Recoupment Policy, or Clawback Policy. This policy covers recoupment of certain incentive compensation paid to certain of our officers, including each of our NEOs. Incentive compensation includes any performance bonuses or incentive awards, including short and long-term incentive bonuses (in cash or otherwise) and all forms of equity-based awards that are granted, earned or vested under any TETRA plan, arrangement or agreement based wholly or in part on the attainment of a financial reporting measure. The policy provides a mechanism to recoup incentive compensation in the event we are required to prepare a restatement of our previously issued financial statements to correct one or more errors that are material to those financial statements (other than to comply with changes in applicable accounting principles or


~~2021 Proxy Statement~~		~~TETRA Technologies, Inc. I~~ 63

to reflect retrospective reclassification or adjustment in accordance with applicable SEC rules and regulations) due to our material noncompliance with any financial requirement under the federal securities laws or in the event that our board concludes that a covered officer engaged in misconduct that caused significant financial or reputational harm to us but did not cause the need for a restatement of our financial statements.

Severance Plan and Termination Payments

With the exception of ~~the~~ ~~Transition Agreement with Mr. Wallace, the offer of employment to Mr. O’Brien, and~~ the Change of Control Agreements described below, we do not have a defined severance plan for, or any agreement with, any Named Executive Officer that would require us to make any termination payments.

~~Transition Agreement with Mr. Wallace.~~ In connection with Mr. Wallace’s retirement as Senior Vice President and General Counsel, on July 22, 2020, we entered into a Transition Agreement (the “Agreement) with Mr. Wallace. The Agreement extends Mr. Wallace’s employment with the Company in a non-executive capacity through July 26, 2022 (the “Transition Period”). During the Transition Period, Mr. Wallace will receive an annualized base salary of $192,500. With respect to his outstanding annual and long-term cash incentive awards, Mr. Wallace is eligible to receive award payments to the extent the applicable performance objectives are met. Unvested equity awards outstanding on the date of the Agreement will continue to vest during the Transition Period pursuant to the vesting schedule in the applicable award agreement.

In addition, Mr. Wallace may terminate his employment with the Company for “Good Reason,” as specified in the Agreement, or for any other reason upon ten (10) days’ advance written notice (a “Voluntary Resignation”). The Agreement also provides that Mr. Wallace’s employment may be terminated by the Company with or without “Cause,” as specified in the Agreement, and his employment will also terminate if he commences employment with a third party or provides services to a third party under certain circumstances.

Subject to the provisions of the Agreement, if Mr. Wallace is terminated by the Company other than for Cause, or if Mr. Wallace terminates his employment for “Good Reason,” then, among other benefits (i) the Company shall continue to pay his base salary through July 26, 2022 and pay an amount equal to any outstanding annual cash incentive award and long-term cash incentive awards that are earned; and (ii) all outstanding restricted stock awards will become fully vested and all other outstanding time-based equity awards shall continue to vest pursuant to the vesting schedule in the applicable award. Subject to the provisions of the Agreement, if Mr. Wallace’s employment terminates as a result of a Voluntary Resignation, his reemployment with a third party or the expiration of the Transition Period, Mr. Wallace will be entitled to other severance benefits as set forth in the Agreement.

If his employment is terminated for Cause, Mr. Wallace will not be entitled to any severance benefits or Change of Control Benefits (as defined below). The Agreement also contains change of control provisions that replace Mr. Wallace’s existing Change of Control Agreement. If a “Change of Control,” as specified in the Agreement, either (i) occurs during the Transition Period and Mr. Wallace is not retained as the general counsel of the successor entity, or (ii) Mr. Wallace is retained as the general counsel of the successor entity and is either terminated without Cause or resigns for “Good Reason” during the two year period following the Change of Control, then, subject to the terms of the Agreement, Mr. Wallace will receive, as applicable (a) an amount equal to any earned but unpaid annual cash incentive award and long-term cash incentive award; (b) the target amount of any outstanding annual cash incentive award and long-term cash incentive awards; (c) two times the sum of his “Qualifying Base Salary,” as specified in the Agreement (or $250,000, if greater) plus the target amount of any annual cash incentive award for the year in which such termination occurs; plus (d) an amount equal to the aggregate premiums payable for the continuation of medical and dental benefits for Mr. Wallace and his eligible dependents for two years following such termination.

~~Offer of Employment to Mr. O’Brien.~~ On January 11, 2019, in connection with our initial offer of employment to Mr. O’Brien, we agreed that upon Mr. O’Brien’s termination by us other than for cause prior to the second anniversary date of his employment with us, Mr. O’Brien would receive (i) accelerated vesting of his inducement award of restricted stock units; (ii) a cash payment equal to six months of his base salary plus a prorated portion of the target amount of his annual Cash Incentive Compensation Plan bonus for the year in which he is terminated, both payable within 30 days following his termination; and (iii) continued eligibility to participate in our welfare benefit plans pursuant to the terms of such plans or pursuant to COBRA, and payment or reimbursement for any premium or contribution required to continue such COBRA coverage for a period of six months.

Employment Agreements

We have previously entered into employment agreements with Messrs. Murphy, Serrano, Sanderson, Moeller, ~~O’Brien,~~ and ~~Wallace~~Mucha that are substantially identical to the form of agreement executed by all of our employees. Each agreement evidences the at-will nature of employment and does not guarantee the term of employment, which is entirely at the discretion of the Board of Directors, or otherwise set forth the salary and other compensation of the NEOs, which is established in accordance with the procedures described above.

Double Trigger Change of Control Agreements

We have entered into change of control agreements ("COC Agreements") with each of our current NEOs and certain other members of our Senior Management. Each COC Agreement has an initial two-year term, with an

COMPENSATION DISCUSSION & ANALYSIS

automatic one-year extension on the second anniversary of the effective date (or any anniversary date thereafter) unless a cancellation notice is given at least 90 days prior to the expiration of the then applicable term. Under the COC Agreements, we have an obligation to provide certain benefits to each NEO upon a qualifying termination event that occurs in connection with or within two years following a “change of control” of TETRA. A qualifying termination event under the COC Agreements includes termination of the NEO’s employment by us other than for Cause (as that term is defined in the COC Agreements) or termination by the NEO for Good Reason (as that term is defined in the COC Agreements). For an overview of the specific terms and conditions of the NEOs' COC Agreements, please read the section titled "Potential Payments upon a Change of Control or Termination" below.

Indemnification Agreements

Each of our current directors and NEOs has executed an indemnification agreement that provides that we will indemnify these directors and officers to the fullest extent permitted by our Restated Certificate of Incorporation, Amended and Restated Bylaws and applicable law. The indemnification agreement also provides that our directors and officers will be entitled to the advancement of fees as permitted by applicable law, and sets out the procedures required for determining entitlement to and obtaining indemnification and expense advancement. In addition, our charter documents provide that each of our directors and officers and any person serving at our request as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise is indemnified to the fullest extent permitted by law in connection with any threatened, pending, or completed action, suit, or proceeding (including civil, criminal, administrative, or investigative proceedings) arising out of or in connection with his or her services to us or to another corporation, partnership, joint venture, trust, or other enterprise, at our request. We purchase and maintain insurance on behalf of any person who is a director or officer of the aforementioned corporation, partnership, joint venture, trust, or other enterprise, against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as an officer or director.

Stock Ownership Guidelines

Our Board of Directors has adopted a policy regarding stock ownership guidelines for our directors and executive officers. The stock ownership guidelines provided under the policy are intended to align the interests of our directors and executive officers with the interests of our stockholders. Under this policy, our executive officers must hold shares of our common stock equal to a multiple, based upon position, of their base salary. The multiples applicable to our executive officers are as follows:

Chief Executive Officer, five-times base salary; ~~Chief Operating Officer and~~

Chief Financial Officer, two-times base salary; and,

Senior Vice Presidents, General Counsel, and Vice Presidents, one-times base salary.

Newly elected officers and directors have five years from the date of appointment to achieve compliance with the policy.

As of the date of this report, subject to the transition period described above, all officers and directors are in compliance with the policy.

Tax and Accounting Implications of Executive Compensation

Under Section 162(m) of the Code, publicly-held corporations generally may not take a tax deduction for compensation paid in excess of $1,000,000 in a year with respect to the corporation’s chief executive officer and other named executive officers. The former exception to this $1,000,000 limitation for performance-based compensation was repealed by the Tax Cuts and Jobs Act of 2017.

We may from time-to-time pay compensation to our executive officers that may not be deductible, including payments made under our ~~Cash Incentive Compensation Plan,~~CICP, discretionary bonuses, and other types of compensation outside of our plans. Although tax deductibility is one of the factors we consider in the design of our compensation plans and programs, we believe that our interests are best served by providing competitive compensation opportunities to our NEOs and other members of Senior Management, even if that results in the non-deductibility of certain amounts under the Code.

The Executive Nonqualified Excess Plan is an unfunded deferred compensation plan pursuant to which the Named Executive Officers and non-employee directors may elect to participate. The Named Executive Officers may elect to defer up to 100% of their base salary and performance-based cash incentive compensation. Deferral elections as to annual base salary are due by mid-December, and are effective as of January 1 of the succeeding year. Deferral elections for cash incentive compensation may be made in the December enrollment period, or in a mid-year enrollment period. Deferrals are held for each participant in separate individual accounts in a rabbi trust. Deferred amounts are credited with earnings or losses depending upon the participant’s deemed investment elections from among hypothetical investment election options which are made available. All hypothetical investments are our unfunded obligations. Deferral contributions made by the participant and earnings credited to such contributions are 100% vested. A deferral period and payment date must be irrevocably specified at election for each deferral. In-service distributions may not be withdrawn until two years following the participant’s initial enrollment. Notwithstanding the participant’s deferral election, the participant will receive distribution of his deferral account upon termination of employment or service, as applicable, or upon disability or death. Hardship withdrawals are permitted for unforeseeable emergencies. In the event the Executive Nonqualified Excess Plan is terminated within twelve months of a change in control, the deferred amounts will become payable to each participant.


2022 Proxy Statement		TETRA Technologies, Inc. I 65

COMPENSATION OF EXECUTIVE OFFICERS

Potential Payments upon Termination or Change of Control

As of the date of this Proxy Statement, ~~other than the Transition Agreement with Mr. Brightman,~~ we do not have a defined severance plan for, or any agreement with, any Named Executive Officer that would require us to make any termination payments. We have previously entered into employment agreements with each of our Named Executive Officers that are substantially identical to the form of agreement executed by all of our employees. These agreements evidence the at-will nature of employment, and do not guarantee term of employment, salary, severance or change in control payments.

In addition, we have entered into ~~change of control agreements ("~~COC ~~Agreements")~~Agreements with each of our NEOs and other members of our ~~senior management.~~Senior Management. The COC Agreements have an initial two-year term, with an automatic one-year extension on the second anniversary of the effective date (or any anniversary date thereafter) unless a cancellation notice is given at least 90 days prior to the expiration of the then applicable term. Under the COC Agreements, we have an obligation to provide certain benefits to each Named Executive Officer upon a qualifying termination event that occurs in connection with or within two years following a “change of control” of TETRA. A qualifying termination event under the COC Agreements includes termination of the Named Executive Officer's employment by us other than for Cause (as that term is defined in the COC Agreements) or termination by the Named Executive Officer for Good Reason (as that term is defined in the COC Agreements).

For purposes of the COC Agreements, the following terms generally mean:

“Cause” means a willful breach in any material respect, a conviction (or plea of guilty or nolo contendere) by a court for any felony, or with respect to employment, for a crime involving fraud, embezzlement, dishonesty, or moral turpitude, a failure to substantially follow the reasonable and lawful written instructions or policies of the Board or us, the willful failure to render material services to us, which results in a material neglect of duties.

“Good Reason” means an occurrence of any of the following without the NEO’s written consent: (i) a material diminution in authority, duties, or responsibilities; (ii) a material diminution in base salary, target annual or long-term bonus opportunity, or employee benefits; (iii) a required relocation of more than 50 miles; (iv) our failure to obtain an assumption of the COC Agreements by any successor entity; or, (iv) any other action or inaction that constitutes a material breach by us.

“Change of Control” will be deemed to have occurred upon any of the following events: (i) any person other than us and certain related entities acquiring beneficial ownership of more than 50% of our outstanding shares; (ii) the consummation of a merger or other business combination or reorganization that results in our stockholders prior to any such change owning more than 50% of the voting securities of the surviving entity; (iii) the consummation of the sale or disposition by us of substantially all of our assets, unless such sale or disposition results in our stockholders prior to owning more than 50% of the voting securities of the acquiror; (iv) the approval by our stockholders of a plan of complete liquidation or dissolution; or, (v) the individuals that constitute a majority of our Board cease for any reason to constitute a majority of our Board.

Under the COC Agreements, if a qualifying termination event occurs in connection with or within two years following a change of control, we have an obligation to pay to each Named Executive Officer the following cash severance amounts: (i)(A) an amount equal to the Named Executive Officer's earned but unpaid Annual Bonus (as that term is defined in the COC Agreement) attributable to the immediately preceding calendar year and earned but unpaid Long Term Bonus (as that term is defined in the COC Agreement) attributable to the performance period ended as of the end of the immediately preceding calendar to the extent such amounts would have been paid to the Named

~~COMPENSATION OF EXECUTIVE OFFICERS~~

Executive Officer had the Named Executive Officer remained employed by us, and in each case only to the extent the performance goals for each such bonus were achieved for the respective performance period, plus (B) the Named Executive Officer's prorated target Annual Bonus for the current year, plus (C) an amount equal to the Named Executive Officer's target Long Term Bonus for each outstanding award; plus (ii) the product of 2.99, in the case of Mr. Murphy, or 2, in the case of the other Named Executive Officers, times the sum of the Named Executive Officer's Base Salary and target Annual Bonus amount for the year in which the qualifying termination event occurs; plus (iii) an amount equal to the aggregate premiums and any administrative fees applicable to the Named Executive Officer due to an election of continuation of coverage that the Named Executive Officer would be required to pay if the Named Executive Officer elected to continue medical and dental benefits under our group health plan for the Named Executive Officer and the Named Executive Officer's eligible dependents without subsidy from us for a period of two years following the date of a qualifying termination of the Named Executive Officer's employment. The Agreement also provides for full acceleration of any outstanding stock options, restricted stock units awards (RSUs), and other stock-based awards upon a qualifying termination of the Named Executive Officer's employment to the extent permitted under the applicable plan. All payments and benefits due under the COC Agreement are conditioned upon the execution and nonrevocation by the Named Executive Officer of a release for our benefit. All

COMPENSATION OF EXECUTIVE OFFICERS

payments under the COC Agreement are subject to reduction as may be necessary to avoid exceeding the amount allowed under Section 280G of the Internal Revenue Code of 1986, as amended.

The COC Agreements also contain certain confidentiality provisions and related restrictions applicable to the NEOs. In addition to restrictions upon improper disclosure and use of Confidential Information (as defined in the COC Agreement), each Named Executive Officer agrees that for a period of two years following a termination of employment for any reason, such Named Executive Officer will not solicit our employees or otherwise engage in a competitive business with us as more specifically set forth in the COC Agreement. Such obligations are only applicable to the Named Executive Officer if he receives the severance benefits described above.

Under the TETRA Technologies, Inc. Amended and Restated 2007 Long Term Incentive Compensation Plan, Third Amended and Restated 2011 Long Term Incentive Compensation Plan, and the First Amended and Restated 2018 Equity Incentive Plan the Human Capital Management and Compensation Committee of our Board of Directors may accelerate the vesting of stock options, ~~restricted stock awards,~~RSUs, and other equity-based awards held by plan participants at its sole discretion. The following table quantifies the potential payments to Named Executive Officers who were employed by us as of December 31, ~~2019,~~2021, under the contracts, agreements or plans discussed above in various scenarios involving a change of control or termination of employment, assuming a December 31, ~~2019~~2021 termination date. In addition to the amounts reflected in the table, the Named Executive Officers would receive upon termination any salary earned through December 31, ~~2019,~~2021, and any benefits they would otherwise be entitled to under our 401(k) Plan and Executive Nonqualified Excess Plan.

~~Transition Agreement with Mr. Wallace.~~ In connection with Mr. Wallace’s retirement as Senior Vice President and General Counsel, on July 22, 2020, we entered into a Transition Agreement with Mr. Wallace. Please see the “Severance Plan and Termination Payments” section in the CD&A for a discussion of the specific terms applicable to Mr. Wallace’s Transition Agreement.

CEO Pay Ratio

Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, requires us to disclose the annual total compensation of Mr. Murphy, our CEO, and our median employee, as well as the ratio of their respective annual total compensation to each other (in each case, with annual total compensation calculated in accordance with SEC rules applicable to the Summary Compensation Table). For ~~2020:~~2021:

•Mr. Murphy’s total annual compensation	$~~1,915,531~~4,253,926
•Ratio of CEO to median employee compensation	~~26.6~~46.9 : 1

We used a consistently applied compensation measure to identify the median of the annual total compensation of all of our employees, and to determine the annual total compensation of our CEO. To make them comparable, salaries for newly hired employees who had worked less than a year were annualized, and the target annual bonus amount was applied to their total compensation measure. To identify the median of the annual total compensation of all employees and the median employee’s compensation, we took the following steps:

We determined that our employee population as of December 31, ~~2020~~2021 consisted of ~~1,795~~1,136 full- and part-time employees ~~(including employees of CSI Compressco)~~ located in 14 countries (we do not have temporary or seasonal workers).

We selected December 31, ~~2020~~2021 as our identification date for determining our median employee because it enabled us to make such identification in a reasonably efficient and economic matter.

For our international employees paid in their local currency, we converted each such employee’s total annual compensation as of December 31, ~~2020~~2021 to U.S. dollars; however, we did not make any cost of living adjustment with respect to any of our U.S. or international employees.

The CEO pay ratio reported above is a reasonable estimate calculated in accordance with SEC rules and methods for disclosure. Due to estimates, assumptions, and adjustments, as well as significantly varying workforce structures, CEO pay ratios reported by other companies are not likely to be comparable to our CEO pay ratio.

COMPENSATION OF EXECUTIVE OFFICERS

COMPENSATION RISK

The Human Capital Management and Compensation Committee (the “HCMCC”) of our Board of Directors reviews and evaluates potential risks related to the design of our compensation programs. In its evaluation of our annual and long-term incentive compensation plans that were in effect during ~~2020,~~2021, as well as the incentive compensation arrangements proposed for ~~2021~~2022 as described above, the HCMCC determined that such plans are designed with the appropriate balance of risk and reward relative to our overall business strategy. In addition, the stock ownership guidelines for our executive officers encourage them to focus on the creation of long-term value for stockholders rather than short-term results.

Specifically, under our ~~Cash Incentive Compensation Plan,~~CICP, the amount of each participant’s prospective payment, for both annual and long-term awards, is established as a percentage of annual base salary, and is contingent on performance, including the attainment of targeted levels of performance that include both financial and nonfinancial measures. With respect to long-term ~~Cash Incentive Compensation Plan,~~CICP, attainment of targeted levels of performance is measured over two or more years. Notwithstanding the attainment of any established performance measures, the amount of the annual or long-term cash incentive payment received by any participant is subject to the ultimate discretion of the HCMCC. Further, annual and long-term cash awards are paid only after the HCMCC has reviewed our audited financial statements for the applicable performance period.

Long-term equity incentive awards typically consist of ~~stock options, restricted stock, restricted stock units and/or CSI Compressco phantom units~~RSUs that generally vest ratably over a three-year period. The recipients of such awards can realize an increase in the value of their long-term equity awards only to the extent that our investors benefit from an increase in the market price for our common ~~stock or the CSI Compressco units.~~stock.

Section 16(a) of the Exchange Act requires our directors, executive officers, and persons who own more than 10% of our common stock to file initial reports of ownership and reports of changes in ownership of common stock (Forms 3, 4, and 5) with the SEC and the NYSE. Executive officers, directors, and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all such forms they file.

To our knowledge, and based solely on our review of the copies of such reports, we have received written representations by certain reporting persons that no reports on Form 5 were required and we believe that during the fiscal year ended December 31, 2020, all Section 16(a) filing requirements applicable to our executive officers, directors, and 10% stockholders were complied with in a timely manner with the exception of the Form 4 filing reporting the vesting of restricted stock (one transaction) by Stuart M.

The complete mailing address of our principal executive offices is 24955 Interstate 45 North, The Woodlands, Texas 77380, and our telephone number is (281) 367-1983.

Attendance at the Annual Meeting is limited to stockholders as of the record date (or their authorized representatives) with evidence of their share ownership and our guests.

We intend to hold our annual meeting in person. However, due to the uncertainties surrounding the impact of the coronavirus (COVID-19), it may not be possible or advisable to hold our annual meeting in person and we are planning for the possibility that the annual meeting may be delayed or held by means of remote communication. If we decide to take either such step, we will announce the decision to do so in advance of the annual meeting. If we elect to hold our annual meeting by remote communication, details on how to participate will be issued by press release, filed with the SEC, and posted on our website at http://ir.tetratec.com/events-and-webcasts and filed with the U.S. Securities and Exchange Commission as additional proxy material.

Internet and Electronic Availability of Proxy Materials

As permitted by the rules adopted by the SEC, we are making this proxy statement and related proxy materials available on the internet under the “notice and access” delivery model. The “notice and access” model removes the requirement for public companies to send stockholders a printed set of proxy materials and allows companies instead to deliver to their stockholders a “Notice of Internet Availability of Proxy Materials” and to provide access to the documents over the internet. Our Notice of Internet Availability of Proxy Materials (“Notice”) was first mailed to stockholders of record and beneficial owners on or about April ~~13, 2021.~~11, 2022. The Notice is not a form for voting, and presents only an overview of the more complex proxy materials. Stockholders are encouraged to access and review the proxy materials before voting.

This proxy statement, the form of proxy, and voting instructions are being made available to stockholders on or about April ~~13, 2021~~11, 2022 at www.envisionreports.com/TTI for registered holders and at www.proxyvote.com for beneficial holders. You may also request a printed copy of this proxy statement and the form of proxy by telephone, over the internet or by email by following the instructions printed on your Notice.

Our Annual Report to Stockholders, including financial statements, for the fiscal year ended December 31, ~~2020~~2021 is being made available at the same time and by the same methods. The Annual Report to Stockholders is not to be considered as a part of the proxy solicitation material or as having been incorporated by reference.

In addition, any stockholder may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. Receiving future proxy materials by email will save the cost of printing and mailing documents to stockholders and will reduce the impact of annual meetings on the environment. A stockholder’s election to receive proxy materials by email will remain in effect unless the stockholder terminates it.

General Voting Instructions

Below are instructions on how to vote as well as information on your rights as a stockholder as they relate to voting. Some of the instructions will differ depending on how your stock is held. It is important to follow the instructions that apply to your situation.

GENERAL INFORMATION ABOUT THE MEETING AND VOTING

Stockholder of Record. If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered a stockholder of record and the Notice was sent directly to you by us.

If you are a stockholder of record, you may vote in person at the Annual Meeting. Your Notice will be your evidence of ownership and serve as your authorization to vote in person; we will provide a ballot for you when you arrive at the meeting. If you requested printed copies of the proxy materials, check the appropriate box on the proxy card and bring evidence of your share ownership to the meeting. The proxy card and the evidence of your ownership will serve as your authorization to vote in person.

If you do not wish to vote in person or if you will not be attending the Annual Meeting, you may vote by proxy. You may vote by internet by following the instructions in the Notice or, if you requested printed copies of the proxy materials, you can vote by internet, by telephone, or by delivering your proxy through the mail.

Beneficial Owners. If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and the Notice was forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account.

If you are a beneficial owner, in order to vote in person at the Annual Meeting, you must obtain a valid proxy from the organization that holds your shares and bring evidence of your stock ownership from the organization with you to the meeting.

If you do not wish to vote in person or if you will not be attending the Annual Meeting, you may direct the vote of your shares by following the instructions on the Notice delivered to you by the organization holding your account. Many brokerage firms, banks, broker-dealers, or other similar organizations participate in the Broadridge Financial Solutions, Inc., Online and Telephone Program. This program provides eligible stockholders the opportunity to vote via the internet or by telephone. Voting forms will provide instructions for beneficial owners if the organization holding their account participates in the program or other similar programs.

401(k) Plan Participants. If you participate in our 401(k) Retirement Plan (the “401(k) Plan”) and have contributions allocated to the TETRA stock fund, you are entitled to direct the 401(k) Plan trustee to vote the shares of our common stock credited to your account as of the close of business on the record date. You may deliver your voting instructions to the 401(k) Plan trustee by internet or telephone by following the instructions on your proxy card, or by indicating your voting instructions on your proxy card and returning it by mail. All proxy cards that are properly completed, signed, and returned by mail or submitted via the internet or by telephone prior to May ~~25, 2021~~23, 2022 will be voted. If you return your proxy card with no voting instructions marked, or if you do not return a proxy card or submit voting instructions via the internet or by telephone, your shares will be voted by the trustee as directed by our 401(k) Plan Administrator.

How to Revoke Your Proxy. All valid proxies received prior to the Annual Meeting will be voted in accordance with the instructions so indicated. You may revoke your proxy and change your vote at any time before the final vote at the Annual Meeting. A proxy may be revoked by a stockholder of record at any time before it is exercised by submitting a written revocation or a later-dated proxy to our Corporate Secretary at the mailing address provided above, by voting again via the internet or telephone, or by attending the Annual Meeting in person and so notifying the Inspector of Elections. If you are a beneficial owner and wish to change your vote, you must contact the organization that holds your shares prior to the Annual Meeting to assist you with this process. If you are a 401(k) Plan participant, you may revoke your voting instructions by submitting a new proxy containing your voting instructions via the internet, by telephone, or by delivering a later dated proxy card by mail prior to May ~~25, 2021.~~23, 2022.

Voting Rules

Stockholders Entitled to Vote - the Record Date.

As of the record date, we had issued and outstanding ~~126,407,041~~127,646,966 shares of common stock and no shares of preferred stock.

Quorum Required. A quorum must be present at the Annual Meeting for us to conduct business at the Annual Meeting. To establish a quorum, we need the presence, either in person or by proxy, of holders of a majority of the shares of our common stock issued, outstanding and entitled to vote.

nonvotes to determine whether a quorum is present. Broker nonvotes occur when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power and the nominee has not received voting instructions from the beneficial owner.

Number of Votes. You are entitled to one vote per share of our common stock that you own as of the record date on each matter that is called to vote at the Annual Meeting.

Voting on Proposal No. 1 - Election of Directors. When voting on this proposal, you have two options:

vote FOR a nominee; or

WITHHOLD authority to vote for a nominee.

If a quorum is present at the Annual Meeting, the seven persons receiving the greatest number of votes will be elected to serve as directors. Therefore, any shares that are not voted and votes that are withheld will not influence the outcome of the election of directors. Brokers who have not received voting instructions from the beneficial owner do not have the discretionary authority to vote on the election of directors. Therefore, broker nonvotes will not be considered in the vote totals and will have no effect on the vote regarding the election of directors. However, as described in greater detail in the “Corporate Governance” section of this proxy, our Board of Directors has adopted a majority vote policy that applies to the election of directors. Under this policy, in an uncontested election (i.e., an election where the number of nominees is not greater than the number of directors to be elected), any nominee who receives a greater number of “withheld” votes from his or her election than votes “for” his or her election is required, unless such nominee has previously submitted an irrevocable resignation in accordance with the policy, to tender his or her resignation to the Chairman of the Board. Consequently, the number of “withheld” votes with respect to a nominee will affect whether or not our majority vote policy will apply to that individual. You may not cumulate your votes for any one of the nominees.

Voting on Other Proposals. When voting on Proposal Nos. 2, 3, and 4 you have three options:

vote FOR a given proposal;

vote AGAINST a given proposal; or

ABSTAIN from voting on a given proposal.

Proposal No. 2 - Ratification of the appointment of independent auditors requires the affirmative vote of a majority of the shares having voting power on such matter that are present or represented at the Annual Meeting. Brokers who have not received voting instructions from the beneficial owner have the discretionary authority to vote on this matter. Therefore, broker nonvotes will be included in the vote totals and have the same effect as a vote against this proposal. For the purpose of determining whether the proposal has received a majority vote, abstentions will be included in the vote totals with the result that an abstention will have the same effect as a vote against the proposal.

Proposal No. 3 - Advisory vote to approve the compensation of executive officers is advisory in nature and will not be binding on or overrule any decisions by our Board of Directors or the Human Capital Management and Compensation Committee (“HCMCC”) of our Board of Directors. However, the Board of Directors and the HCMCC value the opinions of our stockholders and, to the extent that there is any significant vote against the compensation of our executive officers, we will consider our stockholders’ concerns, and our Board of Directors will evaluate whether any actions are necessary to address those concerns. Brokers do not have discretionary authority to vote on the advisory vote to approve executive compensation. Consequently, broker nonvotes will not be considered in the vote totals for this proposal and will have no effect on the vote. For the purpose of determining whether the proposal has received a majority vote, abstentions will be included in the vote totals with the result that an abstention will have the same effect as a vote against the proposal.

Proposal No. 4 – ~~Approval~~The stockholder proposal is precatory and, accordingly, is not binding on the Board of Directors or the ~~amendment~~Company and ~~restatement of our 2018 Equity Incentive Plan~~ ~~(i) increase the number of shares of common stock authorized for issuance under the plan and (ii) include awards to our directors who are not employees of TETRA~~ requires the affirmative vote of a majority of the shares having voting power on such matter that are present or represented at the Annual Meeting. Brokers do not have discretionary authority to vote on this proposal. Consequently, broker nonvotes will not be considered in the vote totals for this proposal and will have no effect on the vote. For the purpose of determining whether the proposal has received a majority vote, abstentions will be included in the vote totals with the result that an abstention will have the same effect as a vote against the proposal.

Householding of Annual Meeting Materials

SEC rules regarding the delivery of the notice of internet availability, proxy statements and annual reports permit us, in specified circumstances, to deliver a single set of these reports to any address at which two or more stockholders reside.

We have delivered only one notice of internet availability of the proxy materials or one paper copy proxy statement and annual report, as applicable, to eligible stockholders who share an address, unless we received contrary instructions from any such stockholder prior to the mailing date. If a stockholder prefers to receive separate copies of our notice of internet availability of proxy materials or our proxy statement or annual report, either now or in the future, we will promptly deliver, upon written or oral request, a separate copy of the notice of internet availability of proxy materials or our proxy statement or annual report, as requested, to that stockholder at the shared address to which a single copy was delivered. Such requests should be communicated to our transfer agent, Computershare Investor Services, either by sending a request in writing to 462 South 4^th Street, Suite 1600, Louisville, KY 40202, or by calling 1-866-641-4276.

Appendix A – Information Regarding Non-GAAP Financial Measures

APPENDIX A – INFORMATION REGARDING

NON-GAAP FINANCIAL MEASURES

Statement Regarding Use of Non-GAAP Financial Measures

In addition to financial results determined in accordance with U.S. GAAP, this proxy may include the following non-GAAP financial measures for the Company: consolidated and segment adjusted EBITDA, adjusted free cash flow from continuing operations, net debt, liquidity, return on capital employed and cash from operations per share. The following schedules provide reconciliations of the non-GAAP financial measures included in this proxy to their most directly comparable U.S. GAAP measures. The non-GAAP financial measures should be considered in addition to, not as a substitute for, financial measures prepared in accordance with U.S. GAAP, as more fully discussed in the Company’s financial statements and filings with the Securities and Exchange Commission.

Adjusted EBITDA for external reporting purposes is defined as earnings before interest, taxes, depreciation, amortization, impairments, and certain non-cash charges, non-recurring adjustments and discontinued operations. Adjusted EBITDA for compensation purposes also excludes adjusted realized and unrealized income or loss from investments and certain board and executive compensation, which are considered outside of management’s control. Adjusted EBITDA is used by management as a supplemental financial measure to assess the financial performance of the Company’s assets, without regard to financing methods, capital structure or historical cost basis and to assess the Company’s ability to incur and service debt and fund capital expenditures. Management believes that the exclusion of the special charges from the historical results of operations enables management to evaluate more effectively the Company’s operations over the prior periods and to identify operating trends that could be obscured by the excluded items.

Adjusted free cash flow from continuing operations is defined as cash from operations less discontinued operations EBITDA and discontinued operations capital expenditures, less capital expenditures net of sales proceeds and cost of equipment sold and including cash distributions to TETRA from CSI Compressco and cash from other investments. Management uses this supplemental financial measure to:

assess the Company’s ability to retire debt;

evaluate the capacity of the Company to further invest and grow; and

to measure the performance of the Company as compared to its peer group.

Adjusted free cash flow from continuing operations do not necessarily imply residual cash flow available for discretionary expenditures, as they exclude cash requirements for debt service or other non-discretionary expenditures that are not deducted.

Net debt is defined as the sum of the carrying value of long-term and short-term debt on its consolidated balance sheet, less cash, excluding restricted cash on the balance sheet. Management views net debt as a measure of TETRA’s ability to reduce debt, add to cash balances, pay dividends, repurchase stock, and fund investing and financing activities.

Liquidity is defined as availability under our asset-based credit agreement (“ABL Credit Agreement”), cash and cash equivalents and specific cash payment timing adjustments. Management views liquidity as a measure of TETRA’s ability to fund operating activities and service debt.

Return on capital employed is defined as Adjusted EBIT divided by average net capital employed, where Adjusted EBIT is defined as earnings before interest, taxes, and certain non-cash charges, non-recurring adjustments and discontinued operations; net capital employed is defined as assets, excluding assets associated with discontinued operations, plus impaired assets, receivables from CSI Compressco, less investment in CSI Compressco, less cash and current liabilities, excluding current liabilities associated with discontinued operations; and average net capital employed is calculated as the average of net capital employed for the respective periods. Return on capital employed is used by management as a supplemental financial measure to assess the financial performance of the Company relative to assets, without regard to financing methods or capital structure.

Cash from operations per share is defined as Adjusted EBITDA for compensation purposes, less interest expense and cash taxes, plus cash distributions to TETRA from CSI Compressco and cash from other investments; divided by weighted average common shares outstanding.

Notwithstanding anything in this Plan to the contrary, no repricing of Options or SARs may be effectuated without the prior approval of the Company's stockholders; provided, however, that the foregoing prohibition shall not apply to the extent an adjustment is required under ~~Section 15~~.

~~(d)Awards to Foreign Service Providers~~. The Administrator may grant Awards to Service Providers who are foreign nationals, who are located outside of the United States or who are not compensated from a payroll maintained in the United States, or who are otherwise subject to (or could cause the Company to be subject to) legal or regulatory requirements of countries outside of the United States, on such terms and conditions different from those specified in this Plan as may, in the judgment of the Administrator, be necessary or desirable to comply with applicable foreign laws and regulatory requirements and to promote achievement of the purposes of this Plan. In connection therewith, the Administrator may establish such subplans and modify exercise procedures and other Plan rules and procedures to the extent such actions are deemed necessary or desirable, and may take any other action that it deems advisable to obtain local regulatory approvals or to comply with any necessary local governmental regulatory exemptions.

~~(e)Effect of Administrator's Decision. The Administrator's decisions, determinations, actions and interpretations shall be final, conclusive and binding on all persons having an interest under~~ ~~this~~ ~~Plan.~~

~~(f)Indemnification~~.

In addition, to be entitled to indemnification, the Indemnitee must, within thirty (30) days after written notice of the Claim, offer the Company, in writing, the opportunity, at the Company's expense, to defend the Claim. The right to indemnification shall be in addition to all other rights of indemnification available to the Indemnitee.

5.~~Eligibility. With the exception of Incentive Stock Options, Awards may be granted to Employees,~~ ~~and~~ ~~Consultants,~~ ~~and Outside Directors. Incentive Stock Options may be granted only to Employees.~~

6.~~Limitations~~.

~~(a)$100,000 Limitation for Incentive Stock Options~~. Each Option shall be designated in the Award Agreement as either an Incentive Stock Option or a Nonqualified Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by a Participant during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100~~,000, such Options shall be treated as Nonqualified Stock Options. For purposes of this~~ ~~Section 6(a)~~, Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Options with respect to such Shares are granted.

~~(b)Special Annual Limits. Subject to~~ ~~Section 15(a)~~ ~~of this Plan, the maximum number of Shares that may be subject to Options or Stock Appreciation Rights granted to any~~ ~~Employee or Consultant~~ ~~Service~~ ~~Provider~~ ~~in any calendar year shall equal one million (1,000,000) Shares. Subject to~~ ~~Section 15(a)~~ ~~of this Plan, the maximum number of Shares that may be subject to Restricted Stock, Restricted Stock Units, Performance Shares, Performance Units and Other Stock-Based Awards granted to any~~ ~~Service Provider~~ ~~Employee or Consultant~~ ~~in any calendar year shall equal one million (1,000,000) Shares.~~ ~~No Outside Director may be granted during any calendar year Awards having an aggregate Fair Market Value, determined on the Date of Grant, in excess of $300,000.~~

~~(c)Minimum Vesting Requirement~~. Except as permitted under the Carve-Out Exception (defined below), all Awards that are designated to be settled in Shares shall be subject to a minimum vesting requirement of at least one year from the date the Award was granted, and no portion of any such Award may vest or become exercisable earlier than the first anniversary of the date such Award was granted; provided, however, that the foregoing minimum vesting requirement shall not apply: (i) with respect to 5% of the Share reserve as initially set forth in ~~Section 3(a)~~ ~~(such 5% being the “Carve-Out Exception~~”), and (ii) to the vesting of an Award that is accelerated as a result of a Change in Control under terms consistent with this Plan. For purposes of clarity and avoidance of doubt, the vesting of Awards that have not been held by a Participant for at least one year from the Date of Grant may be accelerated (in whole or in part) in accordance with the terms of this Plan, however, any such acceleration, other than in connection with a Change in Control, within such one-year period with respect to Awards designated to be settled in Shares shall be included in, and reduce the number of Shares available under, the Carve-Out Exception. To the extent ~~Section 3(a)~~ ~~is amended to~~

~~increase the number of Shares reserved therein, then 5% of the Shares subject to such increase shall be added to, and increase, the number of Shares subject to the Carve-Out Exception.~~

~~Options~~.

~~(a)Grant of Options~~. Subject to the terms and provisions of this Plan, the Administrator, at any time and from time to time, may grant Options to Service Providers in such amounts as the Administrator, in its sole discretion, shall determine.

Each Award of an Option shall be evidenced by an Award Agreement that shall specify the Date of Grant, exercise price, the term of the Option, the number of Shares subject to the Option, the exercise restrictions (if any) applicable to the Option, and such other terms and conditions as the Administrator, in its sole discretion, shall determine.

~~(c)Term of Option~~. The term of each Option shall be stated in the Award Agreement. In the case of an Incentive Stock Option, the term shall be 10 years from the Date of Grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than 10% of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option shall be five years from the Date of Grant or such shorter term as may be provided in the Award Agreement.

~~(d)Option Exercise Price and Consideration~~.

~~(i)Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the exercise of an Option shall be determined by the Administrator, subject to the following:~~

~~(1)In the case of an Incentive Stock Option:~~

(A)granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than 10% of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the Date of Grant; and

(B)granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price shall be not less than 100% of the Fair Market Value per Share on the Date of Grant.

(2)In the case of a Nonqualified Stock Option, the per Share exercise price shall be determined by the Administrator, but shall not be less than the Fair Market Value per Share on the Date of Grant unless the terms of such Nonqualified Stock Option would otherwise comply with the exemption from taxation under Section 409A of the Co~~de.~~

(3)Notwithstanding the foregoing, Options may be granted with a per Share exercise price of less than 100% of the Fair Market Value per Share on the Date of Grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code.

~~(ii)Waiting Period and Exercise Dates~~. At the time an Option is granted, the Administrator shall fix the period within which the Option may be exercised and shall determine any conditions that must be satisfied before the Option may be exercised. Subject to the provisions of ~~Section 6(c), the Administrator may, in its sole discretion, accelerate the satisfaction of such conditions at any time.~~

~~(e)Form of Consideration~~. The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator shall determine the acceptable form of consideration at the time of grant. Such consideration, to the extent permitted by Applicable Laws, may consist entirely of:

~~(i)cash;~~

~~(ii)check;~~

~~(iii)in the discretion of the Administrator, other Shares which meet the conditions established by the Administrator to avoid adverse accounting consequences;~~

~~(iv)in the discretion of the Administrator, consideration received by the Company under a cashless exercise or net exercise program implemented by the Company in connection with this Plan;~~

(v)in the discretion of the Administrator, a reduction in the amount of any Company liability to the Participant, including any liability attributable to the Participant's participation in any Company-sponsored deferred compensation program or arrangement;

~~(vi)in the discretion of the Administrator, any combination of the foregoing methods of payment; or~~

~~(vii)in the discretion of the Administrator, any other consideration and method of payment for the issuance of Shares permitted by Applicable Laws.~~

~~(f)Exercise of Option~~.

~~(i)Procedure for Exercise; Rights as a Stockholder. Any Option granted under this Plan shall be exercisable according to the terms of~~ ~~this~~ ~~Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option shall be deemed exercised when the Company receives: (x)~~ written or electronic notice of exercise (in accordance with the Award Agreement) from the person entitled to exercise the Option, and (y) full payment for the Shares with respect to which the Option is exercised (including provision for any applicable tax withholding). Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and ~~this~~ Plan. Shares issued upon exercise of an Option shall be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Awarded Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in ~~Section 15~~ of ~~this~~ Plan or the applicable Award Agreement. Exercising an Option in any manner shall decrease the number of Shares thereafter available for purchase under the Option by the number of Shares as to which the Option is exercised.

~~(ii)Termination of Relationship as a Service Provider (Other Than Death or Disability)~~. If a Participant ceases to be a Service Provider, other than upon the Participant's death or Disability, the Participant may exercise the vested portion of his or her Option within the time period specified in the Award Agreement (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). If the Award Agreement does not specify a time period within which the vested portion of such Option must be exercised following a Participant ceasing to be a Service Provider, the vested portion of such Option shall be exercisable for three (3) months following his or her ceasing to be a Service Provider (other than upon the Participant's death or Disability). Unless otherwise provided by the Administrator, if the Participant is not vested as to his or her entire Option on the date he or she ceases to be a Service Provider (other than upon the Participant's death or Disability), then immediately thereafter, the Shares covered by the unvested portion of the Option shall again be available for grant under this Plan as set forth in ~~Section 3. Additionally, if the Participant does not exercise his or her Option as to all of the vested Shares within the specified time period, then immediately thereafter,~~ ~~the Option shall terminate and~~ ~~the Shares covered by the unexercised portion of the Option shall again be available for grant under this Plan as set forth in~~ ~~Section 3~~.

~~(iii)Disability of Participant~~. If a Participant ceases to be a Service Provider as a result of his or her Disability, the Participant may exercise the vested portion of his or her Option within the time period specified in the Award Agreement (but in no event later than the expiration of the term of the Option as set forth in the Award Agreement). If the Award Agreement does not specify a time period within which the vested portion of such Option must be exercised following a Participant ceasing to be a Service Provider as a result of his or her Disability, the vested portion of such Option shall be exercisable for twelve (12) months following the Participant ceasing to be a Service Provider as a result of his or her Disability. Unless otherwise provided by the Administrator, if the Participant is not vested as to his or her entire Option on the date he or she ceases to be a Service Provider as a result of his or her Disability, then immediately thereafter, the Shares covered by the unvested portion of the Option shall again be available for grant under this Plan as set forth in ~~Section 3. Additionally, if the Participant does not exercise his or her Option as to all of the vested Shares within the specified time period, then immediately thereafter,~~ ~~the Option shall terminate and~~ ~~the Shares covered by the unexercised portion of the Option shall again be available for grant under this Plan as set forth in~~ ~~Section 3~~.

~~(iv)Death of Participant~~. If a Participant dies while a Service Provider, the vested portion of the Option may be exercised within the time period specified in the Award Agreement (but in no event later than the expiration of the term of the Option as set forth in the Award Agreement), by the beneficiary designated by the Participant prior to his or her death in accordance with ~~Section 26~~. If the Award Agreement does not specify a time period within which the vested portion of such Option must be exercised following a Participant's death, the vested portion of such Option shall be exercisable for twelve (12) months following his or her date of death. Unless otherwise provided by the Administrator, if the Participant is not vested as to his or her entire Option on the date he or she ceases to be a Service Provider as a result of his or her death, then immediately thereafter, the Shares covered by the unvested portion of the Option shall again be available for grant under this Plan as set forth in ~~Section 3. Additionally, if the Participant's beneficiary designated pursuant to~~ ~~Section 26~~ ~~does not exercise the Option as to all of the vested Shares within the specified time period, then immediately thereafter,~~ ~~the Option shall terminate and~~ ~~the Shares covered by the unexercised portion of the Option shall again be available for grant under this Plan as set forth in~~ ~~Section 3~~.

8.~~Restricted Stock~~.

~~(a)Grant of Restricted Stock. Subject to the terms and provisions of~~ ~~this~~ ~~Plan, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, shall determine.~~

~~(b)Restricted Stock Agreement~~. Each Award of Restricted Stock shall be evidenced by an Award Agreement that shall specify the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, shall determine.

~~(c)Removal of Restrictions. Subject to the provisions of~~ ~~Section 6(c), the Administrator may, in its sole discretion, accelerate the time at which any restrictions shall lapse or be removed.~~

~~(d)Voting Rights~~. Service Providers holding Shares of Restricted Stock may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise as set forth in the Award Agreement.

~~(e)Dividends and Other Distributions~~. Shares of Restricted Stock shall be entitled to receive all dividends and other distributions paid with respect to such Shares. All such dividends and distributions shall be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid and no such dividends or other distributions shall be issued or granted with respect to shares of Restricted Stock, and instead shall be held by the Company and delivered to the Participant, if at all, only upon such Awards becoming vested.

~~(f)Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions have not lapsed shall again be available for grant under this Plan as set forth in~~ ~~Section 3~~.

9.~~Stock Appreciation Rights~~.

~~(a)Grant of SARs. Subject to the terms and conditions of~~ ~~this~~ Plan, a SAR may be granted to a Service Provider at any time and from time to time as shall be determined by the Administrator in its sole discretion. The Administrator shall have complete discretion to determine the number of SARs granted to any Service Provider. Subject to the provisions of ~~Section 6(c), the Administrator shall have complete discretion to determine the terms and conditions of SARs granted under~~ ~~this~~ Plan, including the sole discretion to accelerate exercisability at any time; provided, however, that the per Share exercise price that will determine the amount of the payment the Company receives upon exercise of a SAR shall not be less than the Fair Market Value per Share on the Date of Grant.

~~(b)SAR Agreement~~. Each SAR grant shall be evidenced by an Award Agreement that shall specify the Date of Grant, exercise price, the term, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, shall determine.

~~(c)Expiration of SARs. A SAR granted under~~ ~~this~~ Plan shall expire upon the date determined by the Administrator, in its sole discretion, as set forth in the Award Agreement; provided, however, no SAR shall be exercisable later than 10 years after the Date of Grant. Notwithstanding the foregoing, the rules of ~~Sections 7(f)(ii)~~, ~~7(f)(iii)~~ ~~and~~ ~~7(f)(iv)~~ ~~shall also apply to SARs.~~

~~(d)Payment of SAR Amount. Upon exercise of a SAR, a Participant shall be entitled to receive payment from the Company in an amount determined by multiplying:~~

~~(i)The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times~~

~~(ii)The number of Shares with respect to which the SAR is exercised.~~

~~At the sole discretion of the Administrator, the payment upon the exercise of a SAR may be in cash, in Shares of equivalent value, or in some combination thereof.~~

~~10.Performance Units and Performance Shares~~.

~~(a)Grant of Performance Units and Performance Shares. Subject to the terms and conditions of~~ ~~this~~ Plan, Performance Units and Performance Shares may be granted to Service Providers at any time and from time to time, as shall be determined by the Administrator in its sole discretion. The Administrator shall have complete discretion in determining the number of Performance Units and Performance Shares granted to each Service Provider.

~~(b)Value of Performance Units and Performance Shares~~. Each Performance Unit and Performance Share shall have an initial value established by the Administrator on or before the Date of Grant. Each Performance Share shall have an initial value equal to the Fair Market Value of a Share on the Date of Grant.

~~(c)Performance Goals and Other Terms~~. The Administrator shall set Performance Goals in its sole discretion which, depending on the extent to which they are met, shall determine the number or value of Performance Units and Performance Shares that shall be paid out to the Participant. Each Award of Performance Units or Performance Shares shall be evidenced by an Award Agreement that shall specify the Date of Grant, Performance Period and such other terms and conditions as the Administrator in its sole discretion shall determine. The Administrator may set Performance Goals based upon the achievement of Company‑wide, divisional, or individual goals (including solely continued service) or any other basis determined by the Administrator in its sole discretion.

~~(d)Earning of Performance Units and Performance Shares~~. After the applicable Performance Period has ended, the holder of Performance Units or Performance Shares shall be entitled to receive a payout of the number of Performance Units or Performance Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding Performance Goals have been achieved. After the grant of Performance Units or Performance Shares, and subject to the provisions of ~~Section 6(c), the Administrator may, in its sole discretion, reduce or waive any performance objectives for the Performance Unit or Performance Share.~~

~~(e)Form and Timing of Payment of Performance Units and Performance Shares~~. Payment of earned Performance Units and earned Performance Shares, if any, shall be made after the expiration of the applicable Performance Period at the time determined by the Administrator. The Administrator, in its sole discretion, may pay earned Performance Units and Performance Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Units or Performance Shares, as applicable, at the close of the applicable Performance Period) or in a combination of cash and Shares.

~~(f)Cancellation of Performance Units or Performance Shares~~. On the date set forth in the Award Agreement, all unearned or unvested Performance Units and Performance Shares shall be forfeited to the Company, and the Shares subject to such Awards (if any) shall again be available for grant under ~~this~~ ~~Plan as set forth in~~ ~~Section 3~~.

~~11.Restricted Stock Units~~. Restricted Stock Units shall consist of Shares of Restricted Stock, Performance Shares or Performance Unit Awards that the Administrator, in its sole discretion, permits to be paid out in a lump sum, installments or on a deferred basis, in accordance with rules and procedures established by the Administrator.

~~12.Other Stock-Based Awards and Cash-Based Awards. Other Stock-Based Awards may be granted either alone, in addition to, or in tandem with, other Awards granted under~~ ~~this~~ ~~Plan and/or cash awards made outside of~~ ~~this~~ Plan. The Administrator shall have authority to determine the Service Providers, to whom and the time or times at which, Other Stock-Based Awards shall be made, the amount of such Other Stock-Based Awards, and all other terms and conditions of the Other Stock-Based Awards, including any dividend or voting rights and whether the Award should be paid in cash. Cash-based awards may be granted in such amounts and subject to such other terms as the Administrator, in its discretion, determines to be appropriate.

~~13.Leaves of Absence~~. Unless the Administrator provides otherwise, vesting of Awards granted under this Plan shall be suspended during any unpaid leave of absence and shall resume on the date the Participant returns to work on a regular schedule as determined by the Company; provided, however, that no vesting credit shall ~~be awarded for the time vesting has been suspended during such leave of absence. A Service Provider shall not cease to be an Employee in the case of~~ (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no leave of absence may exceed 90 days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not guaranteed by statute or contract, then at the end of three months following the expiration of the leave of absence, any Incentive Stock Option held by the Participant shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Nonqualified Stock Option.

~~14.Non-Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner, other than as provided in~~ ~~Section 26~~ or by will or by the laws of descent or distribution following the Participant’s death. An outstanding Award may be exercised during the lifetime of the Participant only by the Participant. If the Administrator makes an Award transferable, such Award Agreement shall contain such additional terms and conditions as the Administrator deems appropriate.

~~15.Adjustments; Dissolution or Liquidation; Change in Control~~.

~~(a)Adjustments for Changes in Capitalization~~. In the event of any equity restructuring (within the meaning of FASB ASC Topic 718) that causes the per share value of Shares to change, such as a stock dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary dividend, the Administrator shall make such adjustments as it deems equitable and appropriate to (i) the aggregate number and kind of Shares or other securities issued or reserved for issuance under this Plan, (ii) the number and kind of Shares or other securities subject to outstanding Awards, (iii) the exercise price of outstanding Options and SARs, and (iv) any maximum limitations prescribed by this Plan with respect to certain types of Awards or the grants to individuals of certain types of Awards. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights of Participants. In either case, any such adjustment shall be conclusive and binding for all purposes of this Plan. No adjustment shall be made pursuant to this ~~Section 15(a)~~ in connection with the conversion of any convertible securities of the Company, or in a manner that would cause Incentive Stock Options to violate Section 422(b) of the Code or cause an Award to be subject to adverse tax consequences under Section 409A of the Code.

~~(b)Corporate Transactions~~.

~~(i)Continuation, Assumption or Replacement of Awards~~. Unless otherwise provided in an applicable Award Agreement or another written agreement between a Participant and the Company, in the event of a Change in Control that involves a Corporate Transaction, then the surviving or successor corporation or a parent or subsidiary entity of the successor corporation (collectively, the “~~Successor Corporation”) may continue, assume or substitute Awards outstanding as of the date of the Corporate Transaction (with such adjustments as may be required or permitted by~~ ~~Section 15(a)), and such Awards or substitutions therefor shall remain outstanding and be governed by their respective terms subject to~~ ~~Section 15(b)(iv)~~ below. A Successor Corporation may elect to continue, assume or substitute only some Awards or portions of Awards. For purposes of the foregoing, an Award shall be considered assumed or substituted if in connection with the Corporate Transaction and in a manner consistent with Code Section 409A (and Code Section 424 if the Award is an Incentive Stock Option) either (1) the contractual obligations represented by the Award are expressly assumed by the Successor Corporation with appropriate adjustments to the number and type of securities subject to the Award and the exercise price thereof that preserves the intrinsic value of the Award existing at the time of the Corporate Transaction, or (2) the Participant has received a comparable equity-based award that preserves the ~~intrinsic value of the Award existing at the time of the Corporate Transaction and contains terms and~~ ~~conditions that are substantially similar to those of the Award.~~

~~(ii)Acceleration~~. Unless otherwise provided in an applicable Award Agreement, in the event of a Change in Control that involves a Corporate Transaction, if and to the extent that outstanding Awards under the Plan are not continued, assumed or replaced in connection with a Corporate Transaction, then:

(1)such outstanding Awards of Options and Stock Appreciation Rights shall become fully vested and exercisable for such period of time prior to the effective time of the Corporate Transaction as is deemed fair and equitable by the Administrator, and shall terminate at the effective time of the Corporate Transaction;

~~(2)such outstanding Awards other than Awards of Options and Stock Appreciation Rights shall fully vest immediately prior to the effective time of the Corporate Transaction; and~~

~~(3)to the extent vesting of any Award is subject to satisfaction of specified performance goals, such Award shall be deemed “fully vested” for purposes of this~~ ~~Section 15(b)(ii)(3)~~ if the performance goals are deemed to have been satisfied at the target level of performance and the vested portion of the Award at that level of performance is proportionate to the portion of the performance period that has elapsed as of the effective time of the Corporate Transaction.

The Administrator shall provide written notice of the period of accelerated exercisability of Option and SAR Awards to all affected Participants. The exercise of any Option or SAR Award whose exercisability is accelerated as provided in this ~~Section 15(b)(ii)~~ ~~shall be conditioned upon the consummation of the Corporate Transaction and shall be effective only immediately before such consummation.~~

~~(iii)Payment for Awards~~. If and to the extent that outstanding Awards under the Plan are not continued, assumed or replaced in connection with a Corporate Transaction, then the Administrator may provide that some or all of such outstanding Awards shall be canceled at or immediately prior to the effective time of the Corporate Transaction in exchange for cash payments to the holders as provided in this Section 15(b)(iii). The Administrator will not be required to treat all Awards similarly for purposes of this Section 15(b)(iii). The payment for any Award canceled shall be in an amount equal to the difference, if any, between (1) the fair market value (as determined in good faith by the Administrator) of the consideration that would otherwise be received in the Corporate Transaction for the number of Shares subject to the Award, and (2) the aggregate exercise price (if any) for the Shares subject to such Award. If the amount determined pursuant to the preceding sentence is not a positive number with respect to any Award, such Award may be canceled pursuant to this Section 15(b)(iii) without payment of any kind to the affected Participant. With respect to an Award whose vesting is subject to the satisfaction of specified performance goals, the number of Shares subject to such an Award for purposes of this Section 15(b)(iii) shall be the number of Shares as to which the Award would have been deemed “fully vested” for purposes of Section 15(b)(iii). Payment of any amount under this Section 15(b)(iii) shall be made in such form, on such terms and subject to such conditions as the Administrator determines in its discretion, which may or may not be the same as the form, terms and conditions applicable to payments to the Company’s stockholders in connection with the Corporate Transaction, and may, in the Administrator’s discretion, include subjecting such payments to vesting conditions comparable to those of the Award canceled, subjecting such payments to escrow or holdback terms comparable to those imposed upon the Company’s stockholders under the Corporate Transaction, or calculating and paying the present value of payments that would otherwise be subject to escrow or holdback terms.

~~(iv)Termination After a Corporate Transaction~~. If and to the extent the Awards are continued, assumed or replaced under the circumstances described in Section 15(b)(i), and if within twenty-four months after the Corporate Transaction the Participant’s status as a Service Provider is terminated by the Company or Successor Corporation without Cause or by the Participant for Good Reason, then:

(1)all outstanding Awards of Options and Stock Appreciation Rights issued to such Participant that are not yet fully exercisable shall immediately become exercisable in full and shall remain exercisable for one year following the date the Participant ceases to be a Service Provider;

~~(2)all outstanding Awards other than Awards of Options and Stock Appreciation Rights shall fully vest immediately upon the date the Participant ceases to be a Service Provider; and~~

~~(3)to the extent vesting of any Award is subject to satisfaction of specified performance goals, such Award shall vest as provided in~~ ~~Section 15(b)(ii)(3), except that the proportionate vesting amount will be determined with respect to the portion of the performance period during which the Participant was a Service Provider.~~

~~For purposes of the foregoing, the term “Good Reason~~” means a voluntary termination by a Participant who is an Employee of his or her employment with the Company or the Successor Corporation because of: (1) a material diminution in the Participant's base salary or bonus opportunity from those applicable to him or her as of th e date immediately prior to such Change in Control; (1) a material diminution in the nature or scope of the Participant's authority, duties or responsibilities from those applicable to him or her as of the date immediately prior to such Change in Control; (3) the Company or the Successor Corpora ~~tion requiring the Participant to be based at any office or location more than fifty (50)~~ miles from where the Participant was based as of the date immediately prior to such Change in Control; or (4) a material breach by the Company or the Successor Corporation of any term or provision of this Plan, an Award Agreement,

~~employment agreement or other contractual agreement (if any) between the Participant and the Company or the Successor Corporation.~~

~~(c)Other Change in Control~~. Unless otherwise provided in an applicable Award Agreement or another written agreement between a Participant and the Company, in the event of a Change in Control that does not involve a Corporate Transaction, the Administrator may, in its discretion, take such action as it deems appropriate with respect to outstanding Awards, which may include: (i) providing for the cancellation of any Award in exchange for payments in a manner similar to that provided in ~~Section 15(b)(iii)~~ or (ii) making such adjustments to the Awards then outstanding as the Administrator deems appropriate to reflect such Change in Control, which may include the acceleration of vesting in full or in part. The Administrator will not be required to treat all Awards similarly in such circumstances, and may include such further provisions and limitations in any Award Agreement as it may deem equitable and in the best interests of the Company.

~~(d)Dissolution or Liquidation~~. Unless otherwise provided in an applicable Award Agreement, in the event of a proposed dissolution or liquidation of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. An Award will terminate immediately prior to the consummation of such proposed action.

~~16.Board and Stockholder Approval; Term of Plan. The Board approved~~ ~~this~~ ~~Plan to be effective on March~~~~15, 201831, 2021, subject to the Company's stockholders approving this Plan within the 12-month period thereafter. The Company's stockholders approved~~ ~~this~~ ~~Plan on May~~ 426, ~~20182021. From its effectiveness,~~ ~~this~~ ~~Plan shall continue in effect for a term of ten (10) years unless terminated earlier under~~ ~~Section 17~~ of ~~this~~ Plan. If the requisite stockholder approval is not obtained within such 12-month period, any Awards granted hereunder will automatically become null and void and of no force or effect. No Awards may be granted under this Plan on or after the date which is ten (10) years following the effective date of this Plan. This Plan will remain in effect until all Awards granted under the Plan have been satisfied or expired.

~~17.Amendment and Termination of this Plan~~.

~~(a)Amendment and Termination. The Board may at any time amend, alter, suspend or terminate~~ ~~this~~ ~~Plan.~~

~~(b)Stockholder Approval. The Company shall obtain stockholder approval of any Plan amendment to the extent necessary to comply with Applicable Laws.~~

~~(c)Effect of Amendment or Termination. No amendment, alteration, suspension, or termination of~~ ~~this~~ Plan shall materially or adversely impair the rights of any Participant without the Participant’s prior written consent, unless such action is required by Applicable Law or stock exchange rules. Termination of ~~this~~ ~~Plan shall not affect the Administrator's ability to exercise the powers granted to it under this Plan with respect to Awards granted under~~ ~~this~~ ~~Plan prior to the date of termination.~~

~~18.~~

~~Conditions upon Issuance of Shares~~.

~~(a)Legal Compliance. Shares shall not be issued pursuant to the exercise of an Award unless the exercise of the Award and the issuance and delivery of such Shares shall comply with Applicable Laws.~~

~~(b)Taxes~~. No Shares shall be delivered under this Plan to any Participant or other person until the Participant or other person has made arrangements acceptable to the Administrator for the satisfaction of any non-U.S., U.S.-federal, U.S.-state, or local income and employment tax withholding obligations, including, without limitation, obligations incident to the receipt of Shares. Upon exercise or vesting of an Award, the Company shall withhold or collect from the Participant an amount sufficient to satisfy such tax obligations, including, but not limited to, by surrender of up to the whole number of Shares covered by the Award sufficient to satisfy the withholding obligations incident to the exercise or vesting of an Award based on the minimum supplemental rate in the applicable jurisdiction.

~~19.No Rights to Awards. No eligible Service Provider or other person shall have any claim to be granted any Award pursuant to~~ ~~this~~ ~~Plan, and neither the Company nor the Administrator shall be obligated to treat Participants or any other person uniformly.~~

~~20.No Stockholder Rights~~. Except as otherwise provided in an Award Agreement, a Participant shall have none of the rights of a stockholder with respect to Shares covered by an Award until the Participant becomes the record owner of the Shares.

~~21.Fractional Shares~~. No fractional Shares shall be issued and the Administrator shall determine, in its sole discretion, whether cash shall be given in lieu of fractional Shares or whether such fractional Shares shall be eliminated by rounding up or down as appropriate.

~~22.Governing Law~~. This Plan, all Award Agreements, and all related matters, shall be governed by the laws of the State of Delaware, without regard to choice of law principles that direct the application of the laws of another state.

~~23.No Effect on Terms of Employment or Consulting Relationship~~. This Plan shall not confer upon any Participant any right as a Service Provider, nor shall it interfere in any way with his or her right or the right of the Company or a Parent or Subsidiary to terminate the Participant's service at any time, with or without cause, and with or without notice.

~~24.Unfunded Obligation. This~~ ~~Section 24~~ shall only apply to Awards that are not settled in Shares. Participants shall have the status of general unsecured creditors of the Company. Any amounts of cash payable to Participants pursuant to ~~this~~ Plan shall be unfunded and unsecured obligations for all purposes, including, without limitation, Title I of the Employee Retirement Income Security Act of 1974, as amended. Neither the Company nor any Parent or Subsidiary shall be required to segregate any monies from its general funds, or to create any trusts, or establish any special accounts with respect to such obligations. The Company shall retain at all times beneficial ownership of any investments, including trust investments, which the Company may make to fulfill its payment obligations under this Plan. Any investments or the creation or maintenance of any trust for any Participant account shall not create or constitute a trust or fiduciary relationship between the Administrator, the Company or any Parent or Subsidiary and Participant, or otherwise create any vested or beneficial interest in any Participant or the Participant's creditors in any assets of the Company or Parent or Subsidiary. The Participants shall have no claim against the Company or any Parent or Subsidiary for any changes in the value of any assets that may be invested or reinvested by the Company with respect to ~~this~~ ~~Plan.~~

~~25.No Guarantee of Tax Consequences~~. The Company, Board, Committee and the Administrator do not make any commitment or guarantee that any United States federal, state, local, or foreign tax treatment will apply or be available under the Plan to any Participant or other person participating or eligible to participate hereunder. Neither the Company, the Board, the Committee, nor the Administrator will be liable to any Participant or any other person as to any expected or realized tax consequences for any Participant or other person due to the grant, exercise, lapse of restriction, vesting, distribution, payment or other taxable event involving any Award. Although the Company may endeavor to (a) qualify an Award for favorable tax treatment in a jurisdiction or (b) avoid adverse tax treatment for an Award, the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid ~~unfavorable tax treatment.~~

~~26.Designation of Beneficiary by Participant~~. Each Participant may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under the Plan is to be paid in case of his or her death before he or she receives any or all of such benefit. Each such designation will revoke all prior designations by the same Participant, must be in the form prescribed by the Administrator, and will be effective only when filed by the Participant in writing with the Administrator (or its delegate), and received and accepted during the Participant’s lifetime. In the absence of any such valid beneficiary designation, benefits remaining unpaid at the Participant’s death will be paid as follows: (i) if a Participant leaves a surviving spouse, payment will be made to such surviving spouse on behalf of the Participant; and (ii) if a Participant leaves no surviving spouse, payment will be made to (A) if there is administration of such Participant’s estate, the executor or administrator of such estate, upon receipt by the Administrator of supporting evidence from the estate that is satisfactory to the Administrator, or (B) if there is no administration of such Participant’s estate, to such Participant’s heirs at law, but only after such heirs are determined by a court of competent jurisdiction and in such proportion as determined by such court in its signed order that is received by, and satisfactory to, the Administrator.

~~27.Requirements of Law and Securities Exchanges~~. The granting of Awards and the issuance or delivery of Shares under the Plan will be subject to all Applicable Laws, and to such approvals by any governmental agencies or national securities exchanges as may be required. Certificates evidencing Shares delivered under the Plan (to the extent that such Shares are so evidenced) may be subject to such stop transfer orders and other restrictions as the Administrator may deem advisable under the rules and regulations of the Securities and Exchange Commission, any securities exchange or transaction reporting system upon which the Common Stock is then listed or to which it is admitted for

~~quotation, and any other Applicable Law. The Administrator may cause a legend or legends to be placed upon such certificates to make appropriate reference to such restrictions.~~

The Company will not be obligated to take any affirmative action in order to cause the exercise of an Award or the issuance of Shares pursuant to the Plan to comply with any Applicable Law. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Administrator or the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority has not been obtained.

~~28.Clawback~~. All compensation and Awards (including any proceeds, gains or other economic benefit the Participant actually or constructively receives upon receipt or exercise of any Award or other receipt or resale of any Shares underlying the Award) will be subject to any Company clawback policy as may be implemented from time to time, including any clawback policy adopted to comply with any Applicable Law (including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act) as set forth in such clawback policy or the Award Agreement. Any such policy may subject a Participant’s Award, and amounts paid or realized with respect to any Award, to reduction, cancelation, forfeiture or recoupment if certain specified events or wrongful conduct occur; such events including, but not limited to, an accounting restatement due to the Company’s material noncompliance with financial reporting regulations or other events or wrongful conduct specified in any such clawback policy.

~~29.No Obligation to Exercise Awards; No Right to Notice of Expiration Date~~. An Award of a Stock Option or a SAR imposes no obligation upon the Participant to exercise the Award. The Company and the Administrator have no obligation to inform a Participant of the date on which a Stock Option or SAR is no longer exercisable except for including such expiration date in the Participant’s Award Agreement.

~~30.Rule 16b-3 Securities Law Compliance for Insiders~~. Transactions under the Plan are intended to comply with all applicable conditions of Rule 16b-3. Any ambiguities or inconsistencies in the construction of the Plan or an Award will be interpreted to give effect to such intention and, to the extent any provision of the Plan or action by the Administrator fails to so comply, i ~~t may be deemed null and void by the Administrator, in its discretion, to the extent permitted by Applicable Laws.~~

~~31.Section 409A~~.

~~(a)General. The Company intends that all Awards be structured to comply with, or be exempt from, Code Section 409A (“Section 409A~~”), such that no adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Participant’s consent, amend this Plan or Awards, adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any such actions intended to (i) exemp t the Plan or any Award from Section 409A, or (ii) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an Award’s grant date. The Company makes no representations or wa ~~rranties as to an Award’s tax treatment under Section 409A or otherwise. The Company and its Subsidiaries will have no obligation under this~~ ~~Section 31~~ ~~or otherwise to avoid the taxes, penalties or interest under Section 409A with respect to any Award and~~ will have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant “nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A.

~~(b)Separation from Service~~. If an Award constitutes “nonqualified deferred compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s employment or consulting relationship will, to the extent necessary to avoid taxes under Section 409A, be made only upon the Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the Participant’s employment or consulting relationship. For purposes of the Plan or any Award Agreement relating to any such payments, references to a “termination,” “termination of employment” or like terms means a “separation from service.”

~~(c)Payments to Specified Employees~~. Notwithstanding any contrary provision in the Plan or any Incentive Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A as determined by the Administrator) due to his or her “separation from service” will, to the extent necessary to avoid taxes under Code Section 409A(a)(1)(B)(i), be delayed for the six-month period immediately following such “separation from service” (or, if earlier, until the specified employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following such six-month period or as

~~soon as administratively practicable thereafter (without interest) but not later than 60 days following the end of such six-month~~ period. Any payments of “nonqualified deferred compensation” under such Award payable more than six months following the Participant’s “separation from service” will be paid at the time or times the payments are otherwise ~~scheduled to be made.~~

~~(d)Payment Upon Vesting or Lapse of Risk of Forfeiture~~. In the case of an Award subject to Section 409A providing for distribution or settlement upon vesting or lapse of a risk of forfeiture, if the time of such distribution or settlement is not otherwise specified in this Plan or the Award Agreement or other governing document, the distribution or settlement shall be made by March 15 of the calendar year next following the calendar year in which such Award vested or the risk of forfeiture lapsed.

~~(e)Timing of Payment~~. In the case of any distribution of any other Award subject to Section 409A, if the timing of such distribution is not otherwise specified in this Plan or the Award Agreement or other governing document, the distribution shall be made not later than the end of the calendar year during which the settlement of the 409A Award is specified to occur.

~~(f)Separate Payment. Each payment that a Participant may receive under this Plan that is subject to Section 409A shall be treated as a “separate payment” for purposes of Section 409A.~~

~~32.No Restriction on Corporate Action~~. Nothing contained in the Plan will be construed to prevent the Company or any Subsidiary from taking any action which is deemed by the Company or such Subsidiary to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Award made under the Plan.

~~33.Severability~~. If any provision of the Plan or any Award Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction as to any person or Award, or would disqualify the Plan or Award under any Applicable Law, such provision will be (a) construed or deemed amended to conform to Applicable Law or (b) if it cannot be construed or deemed amended without, in the determination of the Administrator, materially altering the intent of the Plan or the Award, such provision will be stricken as to such jurisdiction, person or Award Agreement, and thereafter the remainder of the Plan and any such Award Agreement will remain in full force and effect.

~~34.Rules of Construction. In the interpretation of the Plan, except where the context otherwise requires~~

~~(a)“including” or “include” does not denote or imply any limitation;~~

~~(b)“~~or~~” has the inclusive meaning “and/or~~”;

~~(c)the singular includes the plural, and vice versa, and each gender includes each of the others;~~

~~(d)captions or headings are only for reference and are not to be considered in interpreting the Plan;~~

~~(e)any grammatical form or variant of a term defined in the Plan will be construed to have a meaning corresponding to the definition of the term set forth herein;~~

~~(f)the terms “hereof,” “hereto,” “hereunder” and similar terms in the Plan refer to the Plan as a whole and not to any particular provision of the Plan;~~

~~(g)“Section” refers to a Section of the Plan, unless otherwise stated in the Plan;~~

(h)a reference to any statute, rule, or regulation includes any amendment thereto or any statute, rule, or regulation enacted or promulgated in replacement thereof, and the authoritative guidance issued thereunder by an appropriate governmental entity; and

(i)This Plan shall be construed as a whole and according to its fair meaning, and the Plan and any Award Agreement issued hereunder shall not be strictly construed against the Company or the Administrator.
