AMENDED AND RESTATED CHANGE OF CONTROL AGREEMENT

THIS AMENDED AND RESTATED CHANGE OF CONTROL AGREEMENT (the “Agreement”), made and entered into effective as of October 24, 2019 (the “Effective Date”), by and between TETRA Technologies, Inc., a Delaware corporation (the “Company”), and Brady M. Murphy (“Executive”), amends and restates in its entirety the Change of Control Agreement dated as of February 12, 2018 (the “Original Agreement”) between the Company and the Executive.

WHEREAS, the Company and Executive desire to enter into an agreement regarding their respective rights and obligations in connection with a Change of Control during the Term of this Agreement;

THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and Executive hereby amend and restate the Original Agreement to provide, in its entirety, as follows:

1. Term. This Agreement shall begin on the Effective Date and shall continue until the second anniversary of the Effective Date (the “Initial Term”); provided, however, that commencing on the second anniversary of the Effective Date and each anniversary thereafter, the term of this Agreement shall automatically be extended for successive one year periods (each, a “Renewal Term”) (such Initial Term, plus any Renewal Terms, plus, in the event of Executive’s Qualifying Termination for Good Reason, any additional time period necessitated by the Company’s right to cure as set forth in the definition of Good Reason (the “Term”)), unless at least 90 days prior to the expiration of the Initial Term or any Renewal Term the chairman of the board of directors of the Company shall give written notice to Executive that the Term of this Agreement shall cease to be so extended. However, if a Change of Control shall occur during the Term, the Term shall automatically continue in effect for a period of two (2) years from the date of such Change of Control plus, in the event of Executive’s Qualifying Termination for Good Reason, any additional time period necessitated by the Company’s right to cure as set forth in the definition of Good Reason. This Agreement shall automatically terminate upon Executive’s Termination, except as provided in the definition of Protected Period; provided, that Termination of this Agreement shall not (i) alter or impair any rights of Executive arising under this Agreement on or prior to such termination, or (ii) relieve Executive of the covenants and agreements under Section 4 hereof, as applicable.

2. Qualifying Termination. If a Qualifying Termination occurs with respect to the Executive, Executive shall be entitled to the benefits provided in Section 3 hereof. If Executive’s employment terminates for any reason other than for a Qualifying Termination, then Executive shall not be entitled to any benefits under this Agreement; provided that Executive’s right to receive the Accrued Obligations, if any, shall not be affected by this Agreement.

3. Benefits Upon a Qualifying Termination.

(a) Lump Sum. Subject to Section 3(c) and 3(d), if a Qualifying Termination occurs with respect to the Executive, then in addition to the Accrued Obligations, for which no Release of Claims is required, the Company shall pay to Executive, on the 60th day following the Date of Qualifying Termination, an amount, in a single lump sum payment, equal to the sum of:

(i) (A) an amount equal to any unpaid Annual Bonus attributable to the immediately preceding calendar year and an amount equal to any unpaid Long Term Bonus attributable to a performance period ending as of the end of the immediately preceding calendar year, each as would have been paid to Executive if Executive had remained employed with the Company until the date any such Annual Bonus or Long Term Bonus would have been paid, and in each case only to the extent the performance goals for each such bonus were achieved for the respective performance period (if the amount of such Annual Bonus and/or Long Term Bonus has not been calculated as of the Date of Qualifying Termination, then, notwithstanding the initial paragraph of Section 3(a) above, such amounts shall be paid within 10 days of calculation), plus, (B) an amount equal to Executive’s Target Annual Bonus for the Termination Year (prorated from the first day of the performance period to Date of Termination), plus (C) an amount equal to Executive’s Target Long Term Bonus for each outstanding Long Term Bonus award; provided that any payment pursuant to this Section 3(a)(i) shall be in full satisfaction of the Annual Bonus or Long Term Bonus opportunities to which such payment relates and that was awarded to Executive under a plan or agreement between Executive and the Company or an Affiliate; plus

(ii) The product of 2.99 multiplied by the sum of Executive’s Base Salary and an amount equal to the Target Annual Bonus for the Termination Year (not prorated); plus

(iii) An amount equal to the aggregate premiums and any administrative fees applicable to Executive due to election of continuation coverage that  Executive would  be required to pay if Executive elected to continue medical and dental benefits under the Company’s group health plan for Executive and Executive’s eligible dependents for a period of three (3) years following the Date of Termination and Executive was required to pay the full cost of such continuation coverage without subsidy from the Company.  The amount of the payment to Executive pursuant to this Section 3(a)(iii) shall be determined using the premiums Executive would be required to pay for continuation coverage without subsidy from the Company if Executive elected continuation coverage as of the Date of Termination, based on Executive’s coverage elections in effect on day immediately preceding the Date of Termination under the Company’s group health plan.

(b) Awards. Subject to Section 3(c) and 3(d), if a Qualifying Termination occurs with respect to the Executive, then (i) except as expressly prohibited as of the Effective Date by the terms of the applicable plan under which any such award is granted, all stock options, restricted stock, restricted stock units, or other awards based in common stock of the Company held by Executive and not previously vested shall become immediately 100% vested as of the Date of Termination (except with respect to an award that is subject to the Section 409A Rules if such acceleration would result in the imposition of applicable taxes and interest under the Section 409A Rules) and (ii) each stock option shall remain exercisable until the respective expiration dates of such options.  Unless such acceleration is expressly prohibited as of the Effective Date by the terms of the applicable plan under which any such award is granted, the accelerated vesting of all stock options, restricted stock, restricted stock units or other awards required by this Section 3(b) shall govern and have the effect of amending the award agreement relating to the award to be accelerated.

(c) Release. Notwithstanding anything in this Agreement to the contrary, no payment other than payment of the Accrued Obligations shall be made or benefits provided pursuant to this Agreement unless and until Executive signs and returns to the Company within 50 days following

2

the date of a Qualifying Termination, and does not revoke within seven days thereafter, a release and waiver agreement (the “Release of Claims”) in substantially the same form as that attached hereto as Exhibit A, in exchange for the benefits described in this Section 3, releasing and waiving all claims for liability and damages in any way related to Executive’s employment against the Company, its affiliates, their directors, officers, employees and agents, and their employee benefit plans and fiduciaries and agents of such plans.

(d) Section 409A Rules.

(i) This Agreement is intended to comply with the Section 409A Rules and any ambiguous provisions will be construed in a manner that is compliant with or exempt from the application of the Section 409A Rules. If a provision of the Agreement would result in the imposition of applicable taxes and interest under the Section 409A Rules, such provision may be reformed to avoid, to the extent possible, imposition of such taxes and interest and no action taken to comply with the Section 409A Rules shall be deemed to adversely affect any rights or benefits of Executive hereunder.

(ii) To the extent that any reimbursement or benefit in kind hereunder is subject to the Section 409A Rules, such reimbursement or benefit in kind shall be administered in accordance with Treasury Regulation Section 1.409A-3(i)(1)(iv). Specifically, (A) the applicable reimbursements and benefits in kind shall be such reimbursements and benefits in kind allowable pursuant to the Company’s standard policies and procedures as apply to the Company’s executive employees generally, (B) the amounts reimbursed and in-kind benefits under this Agreement during Executive’s taxable year may not affect the amounts reimbursed or in-kind benefits provided in any other taxable year, (C) the reimbursement of an eligible expense shall be made on or before the last day of Executive’s taxable year following the taxable year in which the expense was incurred, (D) the right to reimbursement or an in-kind benefit is not subject to liquidation or exchange for another benefit, and (E) the right to reimbursement of expenses incurred or to provision of benefits in kind shall terminate four years from Executive’s Date of Termination.

(iii) If Executive is a “specified employee” within the meaning of the Section 409A Rules as of his Date of Termination, no distributions or benefits that are subject to, and not otherwise exempt from, the Section 409A Rules shall be made under this Agreement before the date that is six months and two days after the Date of Termination (or, if earlier, the date of Executive’s death).

(iv) If payment of any amount pursuant to this Agreement on the 60th day following the Date of Qualifying Termination would cause such amount to be subject to additional taxes under the Section 409A Rules, such amounts shall be paid in accordance with the terms governing the timing of such payment as provided in the applicable plan or agreement.

4. Restrictions and Obligations of Executive.

(a) Access to, and Acknowledgement of Value of, Confidential Information.  On the basis of certain existing agreements of confidentiality and non-disclosure by Executive for the benefit of the Company, the Company has previously made available to Executive Confidential Information regarding the Company and its business operations and in return for such existing agreements and Executive’s acknowledgements and agreements contained herein, the Company

3

agrees to provide Executive with (i) Confidential Information regarding the Company and its business operations arising after the date hereof and (ii) access to certain of the Company’s customers, prospective customers, vendors and other parties with whom the Company conducts business, which will allow Executive the opportunity to develop business relationships and goodwill with such customers, prospective customers, vendors and other such parties  after the date hereof.  Executive acknowledges and agrees that the Confidential Information is of significant value to the Company and the protection against unauthorized disclosure and use of the Confidential Information and the business relationships and goodwill that may be developed by Executive in performing his/her duties on behalf of the Company is of critical importance to the Company.  The Company and Executive agree that in addition to the Company’s disclosure of the Confidential Information and the business relationships and goodwill that may be developed by Executive in performing his duties on behalf of the Company, the Company’s agreement to make the payments provided in this Agreement to Executive constitutes additional consideration for the Executive’s compliance with the undertakings set forth in this Section 4. Notwithstanding any other provision of this Agreement to the contrary, Executive shall only be required to comply with the provisions of this Section 4 following the Date of Termination if Executive receives the benefits as provided in Section 3 above.

(b) Confidentiality. Executive acknowledges that the Company has previously provided Executive with Confidential Information and will continue to provide Executive with Confidential Information. Executive agrees that Executive will not, while employed by the Company or any affiliate and at any time thereafter, disclose or make available to any other person or entity, or use for Executive’s own personal gain, any Confidential Information, except for such disclosures as required in the performance of Executive’s duties with the Company or as may otherwise be required by law or legal process (in which case Executive shall notify the Company of such legal or judicial proceeding as soon as practicable following his receipt of notice of such a proceeding, and permit the Company to seek to protect its interests and information).  Executive acknowledges and agrees that such Confidential Information is the exclusive property of the Company and will only be used for the benefit of the Company.  Further, Executive waives and releases any claim that he/she should be able to use, for the benefit of any competing person or entity, Confidential Information that was received by Executive while working for the Company.  

(c) Non-Solicitation or Hire. During the term of Executive’s employment with the Company or any affiliate thereof and for a two-year period following Termination for any reason, Executive shall not, directly or indirectly (i) employ or seek to employ any person who is at the Date of Termination, or was at any time within the six-month period preceding the Date of Termination, an officer or senior level employee of the Company or any of its subsidiaries or otherwise solicit, encourage, cause or induce any such employee of the Company or any of its subsidiaries to terminate such employee’s employment with the Company or such subsidiary or to enter into employment with another company (including for this purpose the contracting with any person who was an independent contractor (excluding consultant) of the Company during such period) or (ii) take any action that would interfere with the relationship of the Company or its subsidiaries with their suppliers or customers without, in either case, the prior written consent of the Board.

(d) Non-Competition. During the term of Executive’s employment with the Company, or any affiliate thereof and for a two-year period following Termination for any reason, Executive

4

shall not, directly or indirectly, either individually or on behalf of, in partnership or conjunction with, any person or entity, as owner, officer, director, partner, member, investor, employee, principal, agent, shareholder or in any other capacity or manner whatsoever, be engaged in the Restricted Business anywhere in the Restricted Area.

Nothing contained in this Section 4 shall prohibit or otherwise restrict Executive from acquiring or owning, directly or indirectly, for passive investment purposes not intended to circumvent this Agreement, securities of any entity engaged, directly or indirectly, in a Restricted Business if such entity is a public entity and Executive (i) is not a controlling Person of, or a member of a group that controls, such entity and (ii) owns, directly or indirectly, no more than 3% of any class of equity securities of such entity.

(e) Injunctive Relief. Executive acknowledges that monetary damages for any breach of Section 4(b), (c), and (d) above will not be an adequate remedy and that irreparable injury will result to the Company, its business and property, in the event of such a breach. For that reason, Executive agrees that in the event of a breach, in addition to recovering legal damages, the Company is entitled to proceed in equity for specific performance or to enjoin Executive from violating such provisions.

(f) Severability. The Executive acknowledges and agrees that the restrictive covenants set forth in this Section 4 are reasonable and necessary in order to protect the Company’s valid business interests.  It is the intention of the parties hereto that the covenants, provisions and agreements contained herein shall be enforceable to the fullest extent allowed by law.  If any covenant, provision or agreement contained herein is found by a court having jurisdiction to be unreasonable in duration, scope or character of restrictions, or otherwise to be unenforceable, such covenant, provision or agreement shall not be rendered unenforceable thereby, but rather the duration, scope or character of restrictions of such covenant, provision or agreement shall be deemed reduced or modified with retroactive effect to render such covenant, provision or agreement reasonable or otherwise enforceable (as the case may be), and such covenant, provision or agreement shall be enforced as modified.  If the court having jurisdiction will not review the covenant, provision or agreement, the parties hereto shall mutually agree to a revision having an effect as close as permitted by applicable law to the provision declared unenforceable.  The parties hereto agree that if a court having jurisdiction determines, despite the express intent of the parties hereto, that any portion of the covenants, provisions or agreements contained herein are not enforceable, the remaining covenants, provisions or agreements of this Section 4 shall be valid and enforceable.  Moreover, to the extent that any provision is declared unenforceable, the Company shall have any and all rights under applicable statutes or common law to enforce its rights with respect to any and all Confidential Information or unfair competition by the Executive.

5. Parachute Payment Limitation.

(a) Anything in this Agreement to the contrary notwithstanding, if the Executive is a “disqualified individual” (as defined in Section 280G of the Code), and the severance benefits provided in Section 3, together with any other payments which the Executive has the right to receive, would constitute a “parachute payment” (as defined in Section 280G of the Code), the severance benefits provided hereunder that constitute a parachute payment shall be either (i) reduced (but not below zero) so that the aggregate present value of such payments received by the

5

Executive from the Company will be one dollar ($1.00) less than three times the Executive’s “base amount” (as defined in Section 280G of the Code) and so that no portion of such payments received by the Executive shall be subject to the excise tax imposed by Section 4999 of the Code, or (ii) paid in full, whichever produces the better net after-tax result for the Executive (taking into account any applicable excise tax under Section 4999 of the Code and any other applicable taxes).  

(b) In making any reductions pursuant to Section 5(a), above, the Company shall reduce or eliminate amounts first by reducing those amounts that are not payable in cash, and then by reducing or eliminating cash amounts, in each case in reverse order beginning with amounts, if any, that are to be paid the farthest in time from the Date of Qualifying Termination; provided, however, that no amount that is subject to the Section 409A Rules shall be reduced or eliminated until all amounts that are not subject to the Section 409A Rules have been eliminated, and then all such amounts that are subject to the Section 409A Rules shall not be reduced in reverse order but shall be reduced proportionally. The determination of the base amount, the present value of the parachute payments, and the amount of any benefit to be reduced shall be determined by the Company’s independent auditors, or such other nationally recognized accounting firm mutually acceptable to the Company and Executive, in accordance with the principles of Section 280G of the Code and based upon the advice of any tax counsel selected by such auditors or other accounting firm.  If a reduced payment is made and through error or otherwise that payment, when aggregated with other payments from the Company (or its affiliates) used in determining if a “parachute payment” exists, exceeds one dollar ($1.00) less than three times the Executive’s base amount, the Executive shall immediately repay such excess to the Company upon notification that an overpayment has been made.

6. Miscellaneous Provisions.

(a) Definitions Incorporated by Reference. Reference is made to Annex I hereto for definitions of certain capitalized terms used in this Agreement, and such definitions are incorporated herein by such reference with the same effect as if set forth herein.

(b) No Other Mitigation or Offset; Legal Fees. The provisions of this Agreement are not intended to, nor shall they be construed to, require that Executive mitigate the amount of any payment or benefit provided for in this Agreement by seeking or accepting other employment. The amount of any payment or benefit provided for in this Agreement shall not be reduced by any compensation earned or health benefits received by Executive as the result of employment outside of the Company. Without limitation of the foregoing, the Company’s obligations to Executive under this Agreement shall not be affected by any set off, counterclaim, recoupment, defense or other claim, right or action that the Company may have against Executive. The Company agrees to pay as incurred, to the full extent permitted by law, all legal fees and expenses Executive may reasonably incur as a result of any contest (regardless of the outcome thereof) by the Company or Executive of the validity or enforceability of, or liability under, any provision of this Agreement other than Section 4 or any guarantee of performance thereto (including as a result of any contest by Executive about the amount of any payment pursuant to this Agreement), plus in each case interest on any delayed payment at the applicable Federal rate provided for in Code Section 7872(f)(2)(A).

6

(c) Cooperation. If Executive becomes entitled to benefits under Section 3 of this Agreement, Executive agrees, for a one-year period following the Date of Termination, to provide reasonable cooperation to the Company in response to reasonable requests made by the Company for information or assistance, including but not limited to, participating upon reasonable notice in conferences and meetings, providing documents or information, aiding in the analysis of documents, or complying with any other reasonable requests by the Company including execution of any agreements that are reasonably necessary, provided such cooperation relates to matters concerning Executive’s duties with the Company and the requests do not, in the good faith opinion of Executive, materially interfere with Executive’s other activities.

(d) Successors; Binding Agreement.

(i) Except in the case of a merger involving the Company with respect to which under applicable law the surviving corporation of such merger will be obligated under this Agreement in the same manner and to the same extent as the Company would have been required if no such merger had taken place, the Company will require any successor, by purchase or otherwise, to all or substantially all of the business and/or assets of the Company, to execute an agreement whereby such successor expressly assumes and agrees to perform this Agreement in the same manner and to the same extent as the Company would have been required if no such succession had taken place and expressly agrees that Executive may enforce this Agreement against such successor. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid that executes and delivers the agreement provided for in this Section 6(d)(i) or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law.

(ii) This Agreement shall inure to the benefit of and be enforceable by Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If Executive should die prior to payment of any amount that is otherwise payable under this Agreement, any such amount shall be paid in accordance with the terms of this Agreement to Executive’s beneficiary as designated in writing by Executive and submitted to and accepted by the Company, or to Executive’s estate if no valid beneficiary designation exists or if the beneficiary dies prior to payment of such amount.  If Executive is married and wishes to name a beneficiary other than Executive’s spouse, that spouse must irrevocably consent in writing to the naming of a different beneficiary and such irrevocable written consent must be submitted to and accepted by the Company.  The Company is entitled, but not required, to rely on Executive’s representations as to his marital status and the identity of his spouse, if any, without any duty to inquire.  Executive is required to notify the Company promptly in writing of any change in his marital status.  

(e) Notice. All notices, consents, waivers, and other communications required under this Agreement must be in writing and will be deemed to have been duly given when (i) delivered by hand (with written confirmation of receipt), (ii) sent by facsimile (with confirmation of receipt), provided that a copy is mailed by certified mail, return receipt requested, or (iii) when received by the addressee, if sent by a nationally recognized overnight delivery service, in each case to the appropriate addresses and facsimile numbers set forth below (or to such other addresses and facsimile numbers as a party may designate by notice to the other parties):

Annex-1

shall have been given to him setting forth in detail the reasons for the Company’s intention to terminate for Cause, and if such Termination is pursuant to clause (i), (iii) or (iv) above and such breach or action is curable, only if Executive has been provided a period of thirty (30) days from receipt of such notice to cease the actions or inactions or otherwise cure such breach, and he has not done so; (B) an opportunity shall have been provided for the Executive to be heard before the Board; and (C) if such Termination is pursuant to clause (i), (ii) or (iii) above, delivery shall have been made to Executive of a notice of Termination from the Board finding that in the good faith opinion of a majority of the Board (excluding the Executive, if applicable) that the condition set forth in clause (i), (ii) or (iii) above has been satisfied.

(ii) the consummation of any merger, reorganization, business combination or consolidation of the Company or one of its subsidiaries with or into any other company, other than a merger, reorganization, business combination or consolidation which would result in the holders of the voting securities of the Company outstanding immediately prior thereto holding securities which represent immediately after such merger, reorganization, business combination or consolidation more than 50% of the combined voting power of the voting securities of the Company or the surviving company or the parent of such surviving company;

(iii) the consummation of a sale or disposition by the Company of all or substantially all of the Company’s assets, other than a sale or disposition if the holders of the voting securities of the Company outstanding immediately prior thereto hold securities immediately thereafter which represent more than 50% of the combined voting power of the voting securities of the acquiror, or parent of the acquiror, of such assets;

(iv) the stockholders of the Company approve a plan of complete liquidation or dissolution of the Company; or

excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an election contest with respect to the election or removal of directors or other solicitation of proxies or consents by or on behalf of a person other than the Board.

Notwithstanding the foregoing, however, in any circumstance or transaction in which compensation would be subject to the income tax under the Section 409A Rules if the foregoing definition of “Change of Control” were to apply, but would not be so subject if the term “Change of Control” were defined herein to mean a “change in control event” within the meaning of Treasury Regulation Section 1.409A-3(i)(5), then “Change of Control” means, but only to the extent necessary to prevent such compensation from becoming subject to the income tax under the Section 409A Rules, a transaction or circumstance that satisfies the requirements of both (1)  a Change of Control under the applicable clauses (i) through (v) above, as applicable, and (2) a “change in control event” within the meaning of Treasury Regulation Section 1.409A-3(i)(5).
