THIS TRANSITION AGREEMENT (this “Agreement”) is entered into this 8th day of May, 2019, but effective as of May 3, 2019 (the “Effective Date”), by and between TETRA TECHNOLOGIES, INC., a Delaware corporation (the “Company”) and STUART M. BRIGHTMAN (the “Employee”).

WHEREAS, the Employee has been employed by the Company in various capacities, most recently as its Chief Executive Officer;

WHEREAS, the Employee has as of the Effective Date resigned from the position of Chief Executive Officer and the parties have mutually agreed to continue the Employee’s employment by the Company as herein provided; and

WHEREAS, the Employee and the Company desire to enter into this Agreement to set forth the terms and conditions of the Employee’s continued employment by the Company.

NOW, THEREFORE, in consideration of the mutual covenants and promises herein contained, and intending to be legally bound hereby, the Company and the Employee hereby agree as follows:

1.1The Company hereby agrees to continue to employ the Employee, and the Employee hereby agrees to accept continued employment with the Company, in a non-executive capacity upon the terms and for the period set forth in this Agreement.

1.2Unless sooner terminated in accordance with the terms of this Agreement, the Employee’s term of employment hereunder shall mean the period commencing on the Effective Date and ending five (5) years thereafter, on May 3, 2024 (the “Transition Period”). The Employee acknowledges and agrees, subject to the terms and provisions of this Agreement, that the Employee’s employment with the Company during the Transition Period shall continue to be on an at-will basis and this Agreement shall not establish any term of employment for a fixed term.

2.Duties. During the Transition Period, the Employee shall serve in such positions as the Company’s Chief Executive Officer and/or Board of Directors (the “Board”) may determine from time to time. The Employee shall provide such services as are consistent with his position.

3.1Base Salary. During the Transition Period, the Employee shall receive an annualized base salary equal to $250,000, less applicable withholdings (the “Base Salary”), which shall be paid in accordance with the Company’s standard payroll practice.

3.2Bonus Opportunities. During the Transition Period, the Employee shall no longer be entitled to receive any annual or long-term bonus awards or opportunities. The Company has previously awarded to the Employee the annual cash incentive compensation opportunity (the “Annual Cash Incentive Award”) and the long-term cash incentive compensation opportunities (the “LT Cash Incentive Awards”) set forth on Schedule A that remain outstanding as of the Effective Date.

(a)Annual Cash Incentive Award. Subject to the terms of this Agreement, the Employee is eligible to receive a prorated award payment for the Annual Cash Incentive Award, paid at the same time that payments under similar annual cash incentive awards are made by the Company, but not later than two and one-half (2½) months after the end of the calendar year in which the Annual Cash Incentive Award was earned by the Employee, assuming the Employee is still

employed by the Company at that time. Proration will be based on the number of full months prior to the Effective Date (four (4)) divided by the number of months in the performance period (twelve (12)). The Annual Cash Incentive Award will be paid only to the extent the applicable performance period objectives are met, as determined in accordance with the Cash Incentive Compensation Plan (the “CICP”) (i.e., a payout is not guaranteed), provided that any applicable individual performance goals shall be deemed to have been 100% satisfied.

(b)LT Cash Incentive Awards. Subject to the terms of this Agreement, the Employee is eligible to receive the full amount of the award payment for each of the performance periods covered by the respective LT Cash Incentive Awards listed on Schedule A, paid at the same time that payments under similar long-term cash incentive awards are made by the Company, but not later than two and one-half (2½) months after the end of the respective performance period in which the LT Cash Incentive Award was earned by the Employee, assuming the Employee is still employed by the Company at that time. Each LT Cash Incentive Award will be paid only to the extent the applicable performance period objectives are met, as determined in accordance with the CICP (i.e., a payout is not guaranteed), provided that any individual performance goals shall be deemed to have been 100% satisfied.

3.3Equity-Based Awards. During the Transition Period, the Employee shall no longer be entitled to receive any new equity awards. The Company has previously granted to the Employee the equity awards (the “Outstanding Equity Awards”) as set forth on Schedule B that remain outstanding as of the Effective Date. Unvested stock options included within the Outstanding Equity Awards will continue to vest during the Transition Period pursuant to the vesting schedule set forth in the applicable award agreement. Unvested restricted stock, restricted stock units and stock appreciation rights included within the Outstanding Equity Awards will continue to vest, and the restrictions on such restricted stock awards and restricted stock units will continue to lapse, during the Transition Period pursuant to the vesting schedule set forth in the applicable award agreement.

3.4Employee Benefits. During the Transition Period and subject to the provisions of any applicable plan (including any insurance plan or program), the Employee and/or the Employee’s eligible dependents, as the case may be, shall be eligible to participate in and shall receive all coverage under welfare benefit plans practices, policies and programs provided by the Company (including, without limitation, medical, prescription, dental, disability, employee life, group life, and accidental death insurance plans and programs and the Company’s 401(k) plan, including Company-matching contributions, and deferred compensation plan), to the extent generally available to the executive officers of the Company. Pursuant to Section 1, Employee shall be considered a full-time employee of the Company during the Transition Period.

4.1Death. The Employee’s employment shall terminate automatically upon the Employee’s death during the Transition Period.

4.2Disability. If the Company determines that a Disability (as defined below) of the Employee has occurred during the Transition Period, the Company may give to the Employee a Notice of Termination (as defined below) giving notice of the Company’s intention to terminate the Employee’s employment. In such event, the Employee’s employment with the Company shall terminate effective thirty (30) days after receipt of such Notice of Termination by the Employee (the “Disability Effective Date”). For purposes of this Agreement, “Disability” shall mean and be deemed to have occurred if (i) the Employee is receiving income replacement benefits under the Company’s long-term disability plan, or (ii) in the absence of the Employee’s receipt of such benefits, the Employee has been unable to perform the essential functions of his position, despite any reasonable accommodation required by law, by reason of illness or injury for a total of ninety (90) consecutive days or an aggregate of one hundred eighty (180) days within any given period of three hundred sixty (360) consecutive days.

(a)The Employee may terminate his employment during the Transition Period for (i) Good Reason (as defined below), or (ii) any reason upon ten (10) days’ advance written notice to the Company (a “Voluntary Resignation”). The Employee’s employment will be deemed to be automatically terminated upon (w) the Employee’s commencement of employment with any third party, or (x) unless otherwise agreed in writing by the Chairman of the Board of the Company, the Employee’s commencement of consulting services to any third party under circumstances in which it is reasonably anticipated that the Employee will receive compensation (whether in any combination of cash, equity, property or other consideration) in excess of $300,000 in any consecutive twelve (12) month period (both (x) and (x) being referred to herein as a “Reemployment Termination”). The Employee shall provide prior written notice to the Company of any proposed employment or consulting arrangement, including the name of the counterparty and, in the event of a proposed consulting arrangement, the anticipated amount of compensation payable to the Employee. For clarification, a Reemployment Termination shall not occur as a result of the Employee serving on the board or committee of any third party.

(b)For purposes of this Agreement, “Good Reason” shall mean, without the Employee’s consent, any one of the following: (i) any failure by the Company to comply with any of the provisions of Section 3 hereof that is not remedied by the Company within ten (10) days after the Company’s receipt of written notice thereof by the Employee, and (ii) any failure by the Company to comply with Section 11.3 hereof.

4.4Termination by the Company. The Company may terminate the Employee’s employment during the Transition Period for Cause. For purposes of this Agreement, “Cause” shall mean:

(a)the Employee’s conviction of, or entry of a plea of guilty or nolo contendere of, a felony or any crime involving dishonesty or moral turpitude;

(b)the failure of the Employee to comply in any material respect with any previously announced and disclosed written policy or procedure of the Company including, without limitation, the Company’s Code of Business Conduct, which, if curable, is not cured within ten (10) days after the Employee’s receipt of written notice thereof; or

(c)the Employee’s breach or violation of the covenants and obligations contained in any one of Sections 6, 7 and 8 or the Employee’s engagement in any Competitive Activities (as defined in Section 9.2).

4.5Notice of Termination. Any termination of the Employee’s employment hereunder by the Company or the Employee (other than a termination pursuant to Section 4.1 or Reemployment Termination) shall be communicated by a Notice of Termination to the other party hereto. For purposes of this Agreement, a “Notice of Termination” shall mean a written notice which (i) indicates the specific termination provision in this Agreement relied upon, (ii) in the case of a termination for Disability, Cause or Good Reason, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Employee’s employment under the provision so indicated, and (iii) specifies the Effective Termination Date (as herein defined); provided, however, that a Notice of Termination in connection with a termination for Good Reason shall be given by the Employee within a reasonable period of time, not to exceed forty-five (45) days, following the occurrence of the event giving rise to such right of termination.

4.6Effective Termination Date. For purposes of this Agreement, the “Effective Termination Date” shall mean the effective date of the termination of the Employee’s employment hereunder, which date shall be:

In furtherance of this Section 4.7, the Employee has delivered to the Company an executed irrevocable resignation in the form attached hereto as Exhibit A concurrently with the execution of this Agreement.

5.5Separate Payments. For purposes of Section 409A of the Code, the Employee’s right to receive any payment, benefit or amounts that might otherwise constitute installment payments shall be treated for purposes of Section 409A of the Code as a right to receive a series of separate and distinct payments.

event may the Employee, directly or indirectly, designate the calendar year of any payment to be made under this Agreement, to the extent such payment is subject to Section 409A of the Code.

6.1The Employee acknowledges that during the course of his employment with the Company and in his service as a director to the Company and its CSI Compressco GP Inc. subsidiary, the Employee has been involved, and he will continue to be involved, in the development of the Confidential Information (as herein defined) of the Company and its affiliated companies, and he has had access, and will continue to have access, to Confidential Information relating to the business and affairs of the Company and its affiliated companies. “Confidential Information” means and includes all confidential and/or proprietary information, trade secrets and “know-how” and compilations of information of any kind, type or nature (tangible and intangible, written or oral, and including information contained, stored or transmitted through any electronic medium), whether owned by the Company or its affiliated companies, disclosed to the Company or its affiliated companies in confidence by third parties or licensed from any third parties, which, at any time during the Employee’s employment by the Company or service as a director of the Company or its affiliated companies, is developed, designed or discovered or otherwise acquired or learned by the Employee and which relates to the Company or its affiliated companies, partners, business, services, products, processes, properties or assets, customers, clients, suppliers, vendors or markets or such third parties.

The Employee further acknowledges and agrees that the Company and its affiliated companies have put in place certain policies and practices to safeguard such Confidential Information, and that as a condition of his employment with the Company, the Employee executed an Employment Agreement dated April 20, 2005 (the “Employment Agreement”) with the Company pursuant to which the Employee agreed, both during and after his employment, not to disclose or use for his benefit or the benefit of others any Confidential Information and to comply with the Company’s policies regarding Confidential Information. While the Employee agrees that he continues to be subject to the terms and provisions of such Employment Agreement, including the confidentiality provisions contained therein, as well as the Company’s policies and limitations on disclosure of Confidential Information, the Employee further agrees that both during and after the Employee’s employment with the Company, the Employee will (i) hold all Confidential Information, in strict confidence and will not, directly or indirectly, disclose, make available, discuss, transmit, publish or use such Confidential Information other than for the Company’s benefit and/or the benefit of its affiliated companies and (ii) not, directly or indirectly, disclose, use, cause, facilitate or allow any third party to use such Confidential Information in any way, except as may be (A) authorized by the Company’s Chief Executive Officer in writing, or (B) required by law or applicable legal process.

In making or initiating any such reports or disclosures, Employee need not seek the Company’s prior authorization and is not required to notify the Company of any such reports or disclosures.

7.1During and after the Employee’s employment with the Company, the Employee agrees not to make or publish, to any person or entity or in any public forum any defamatory or disparaging remarks, comments or statements concerning the Company or its affiliated companies.

8.Continuing Obligations. Nothing contained in this Agreement shall be deemed to affect or relieve the Employee from any continuing obligations contained in the Employment Agreement or other policies of the Company to which the Employee is subject during and, as applicable, following his employment with the Company and the Employee agrees to comply with such ongoing obligations in accordance with their terms.

9.1In addition to any rights or remedies set forth in Section 12.6 hereof for any breach by the Employee of any of the covenants or agreements set forth in Sections 6, 7 and 8, (i) the Employee’s employment hereunder and the Company’s payment and provision of the compensation and benefits provided in Section 3, and (ii) the Company’s payment and provision of the Severance Benefits are each conditioned upon the Employee’s compliance with the terms and provisions of Sections 6, 7 and 8, and the Employee not engaging in any Competitive Activity (as defined in Section 9.2). If at any time during the term of the Employee’s employment the Employee shall breach any of the provisions of Sections 6, 7 or 8, or engage in any Competitive Activities, the Company may terminate the Employee’s employment for Cause. If at any time after the Effective Termination Date during which the Severance Benefits are being provided the Employee shall breach any of the provisions of Sections 6, 7, or 8, or engage in any Competitive Activities, the Company shall no longer be required to pay or provide the Severance Benefits and any vested stock options shall be exercisable only for the applicable period following the Effective Termination Date in accordance with the respective stock option agreement and plan.

Notwithstanding the foregoing, a Competing Business shall not include any line of business or business segment that is divested by the Company or any of its affiliated companies so long as the definitive agreements for any such disposition do not otherwise restrict the Employee from engaging in the divested business.

a writing signed by such party, and a waiver on one occasion shall not be deemed to be a waiver of the same or any other type of breach on a future occasion. No failure or delay by a party hereto in exercising any right or power hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right or power.

12.4Notices. All notices required hereunder shall be in writing and shall be given by hand delivery to the other party or by registered or certified mail, return receipt requested, postage prepaid, addressed to the Employee, at the address maintained in the Company’s records, and to the Company as follows:

or to such other address as either party shall have furnished to the other in writing in accordance herewith. Notices and communications shall be effective when actually received by the addressee.

12.5Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

12.6Injunctive Relief. In recognition of the fact that a breach by the Employee of any of the provisions of Sections 6 or 7 or the continuing obligations as provided in Section 8 will cause irreparable damage to the Company and/or its affiliated companies, for which monetary damages alone will not constitute an adequate remedy, the Company shall be entitled as a matter of right (without being required to prove damages or furnish any bond or other security) to obtain a restraining order, an injunction, an order of specific performance, or other equitable or extraordinary relief from any court of competent jurisdiction restraining any further violation of such provisions by the Employee or requiring the Employee to perform the Employee’s obligations hereunder. Such right to equitable or extraordinary relief shall not be exclusive but shall be in addition to all other rights and remedies to which the Company or any of its affiliated companies may be entitled at law or in equity, including without limitation the right to recover monetary damages for the breach of any of the provisions of this Agreement.

12.7Taxes. The Company may withhold from any amounts payable under this Agreement such Federal, state, local or foreign taxes as shall be required to be withheld pursuant to any applicable law or regulation. Notwithstanding any other provision of this Agreement, each party hereto agrees to be responsible for and to pay the taxes imposed on it by applicable law without any contribution from the other.

12.8No Guarantee of Tax Consequences. Notwithstanding anything in this Agreement to the contrary, the Company makes no representation, commitment or guarantee that any federal, state, local or other tax treatment will (or will not) apply or be available with respect to the payments and benefits provided under this Agreement (including whether or not the same are exempt from, or compliant with, Section 409A of the Code) and does not assume any responsibility or liability for all or any portion of any taxes, penalties, interest or other costs or expenses that may be incurred by the Employee (or any person claiming through or on behalf of the Employee) with respect thereto.

12.9Section 409A. The intent of the parties is that the payments and benefits under this Agreement comply with or be exempt from Section 409A of the Code and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. If any provision of this Agreement does not satisfy the requirements of Section 409A of the Code, then such provision shall nevertheless be applied in a manner consistent with those requirements to the extent any payments hereunder are subject to Section 409A of the Code.

(a)This Agreement constitutes the entire agreement between the parties hereto concerning the subject matter hereof and, except for the existing covenants of the Employee, including those in the Employment Agreement, which are intended to be carried forward pursuant to Section 8 of this Agreement, this Agreement shall supersede any other prior agreement or understanding, both written and oral, between the parties with respect to such subject matter.

(b)Upon the execution of this Agreement by the parties hereto, the Change of Control Agreement dated May 30, 2013, by and between the Company and the Employee shall be terminated and no longer in effect.

12.11Captions. The captions herein are inserted for convenience of reference only, do not constitute a part of this Agreement, and shall not affect in any manner the meaning or interpretation of this Agreement.

12.12Multiple Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile or e-mail transmission of any signed original of this Agreement will be deemed the same as delivery of an original.
