This Separation and Release Agreement (the “Agreement”) is entered into effective as of the 26th day of January, 2015 (the “Effective Date”) by and between Edwin H. Goldman (“Employee”) and TETRA Applied Technologies, LLC, a Delaware limited liability company (the “Company”). Capitalized terms not otherwise defined in this Agreement shall have the meaning set forth in Section 6.

WHEREAS, Employee is currently employed by the Company as Senior Vice President and also serves as Senior Vice President of TETRA Technologies, Inc., a Delaware corporation and the sole member of the Company (“TETRA”);

WHEREAS, Employee has as of the Effective Date resigned from the position of Senior Vice President of the Company and TETRA and the parties have mutually agreed to continue Employee’s employment with the Company to assist in the transition of duties and such other matters as the Company may reasonably request; and

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

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

1.Employment. The Company hereby agrees to continue to employ Employee, and Employee hereby agrees to continue employment with the Company, upon the terms set forth herein. The Company and Employee agree that Employee’s employment with the Company following the Effective Date shall terminate on the soonest to occur of (i) July 26, 2015, (ii) termination by either Employee or the Company upon ten (10) days’ prior written notice, and (iii) Employee’s commencement of full- or part-time employment with any third party or Employee’s provision of a material amount of consulting services to a third party (such period of continued employment being referred to as the “Transition Period”). Employee shall provide not less than three (3) days’ prior written notice to the Company of Employee’s commencement of employment with any third party or Employee’s provision of such consulting services. Employee shall have such duties as may be assigned to him by TETRA’s Chief Executive Officer or Chief Operating Officer. During the Transition Period, Employee agrees to devote such time as reasonably required to carry out and perform the responsibilities assigned to Employee.

(a)During the Transition Period, Employee shall continue to receive the monthly base salary as in effect on the Effective Date, less applicable withholdings, which shall be paid in accordance with the Company’s standard payroll practice. In addition, to the extent any annual incentive bonus payable to Employee pursuant to TETRA’s Cash Incentive Compensation Plan is earned for the 2014 fiscal year, Employee shall be entitled to receive such annual incentive bonus in accordance with, and at the time specified in, TETRA’s Cash Incentive Compensation Plan. Employee shall be entitled to participate in all other employee benefit plans during the Transition Period other than the Company’s Cash Incentive Compensation Plan for 2015 and provided that Employee shall not be eligible for any new award under the Company’s equity incentive compensation plans in 2015.

(b)Conditioned upon Employee’s non-revocation of the Age Discrimination in Employment Act (“ADEA”) release contained in Section 4, the Company will pay to Employee, as severance, the sum of $300,000, less applicable withholdings, upon the date that is eight (8) days following the Effective Date.

(c)Upon termination of Employee’s employment with the Company for any reason, Employee shall be entitled to receive (i) all amounts of earned but unpaid base salary accrued through the effective date of termination,

(ii) such employee benefits, if any, as to which Employee may be entitled under the benefit plans, arrangements or policies of the Company to the effective date of termination or as otherwise expressly required by applicable law (including pursuant to the Consolidated Omnibus Reconciliation Act of 1985, as amended (“COBRA”)); provided, that the Company shall not be required to waive, pay or reimburse any premium or contribution required of Employee to continue any COBRA coverage or other benefits except as provided in the following sentence, and (iii) reimbursement of all unpaid expenses incurred prior to the effective date of termination in accordance with the Company’s policies (collectively, the “Accrued Amounts”). In the event of a Qualifying Termination by the Company as provided in clause (i) of the definition of a Qualifying Termination, the Company shall, subject to the conditions set forth in Section 2(d) below, waive, pay or reimburse Employee for any premium or contribution required of Employee to continue COBRA coverage for Employee and his eligible dependents through July 26, 2015.

 

(d)In addition to the Accrued Amounts, for which no release is required, and subject to the conditions set forth below, (i) upon a Qualifying Termination, the Company shall pay to Employee, as severance, in accordance with the Company’s normal payroll practices his current base salary as in effect on the Effective Date, less applicable withholdings through July 26, 2015 (the “Severance Payments”), and (ii) upon either a Qualifying Termination or Employee having continued his employment with the Company through July 26, 2015, as of the date which is eight (8) days following the parties execution of the Release Agreement (as herein defined), (A) all of Employee’s vested options previously granted by TETRA will continue to be exercisable until the sooner to occur of (x) the expiration date set forth in the respective option agreement, and (y) the twelve (12) month anniversary of the effective date of the Qualifying Termination or July 26, 2016, as applicable, and after such applicable extension period the exercise rights with respect to such vested options shall expire, and (B) TETRA will either accelerate the vesting of all unvested shares of restricted stock awarded to Employee pursuant to that certain Employee Restricted Stock Agreement dated May 20, 2013 (the “2013 Award”) or the Company will pay to Employee an amount equal to the Unvested Equity Value (such benefits being referred to as the “2013 Restricted Stock Benefits”). The Severance Payments, extension of the exercise period for the vested options and the 2013 Restricted Stock Benefits provided in clauses (i), (ii) and (iii) of the preceding sentence are collectively referred to as the “Severance Benefits.”

Employee’s receipt of the Severance Payments is conditioned upon the termination of employment being the result of a Qualifying Termination. The extension of the exercise period of the vested options and the 2013 Restricted Stock Benefits are conditioned upon the termination of employment being the result of either a Qualifying Termination or the termination of the Transition Period as a result of Employee having been continuously employed by the Company through July 26, 2015. In addition, Employee’s receipt of the Severance Benefits and the Company’s waiver, payment or reimbursement of any premium or contribution required for the continuation of COBRA coverage as set forth in Section 2(c) above are conditioned upon (i) Employee’s execution and delivery of the Release Agreement attached hereto as Exhibit A (the “Release Agreement”) within forty-five (45) days following the effective date of the Qualifying Termination or July 26, 2015, as applicable, and Employee’s non-revocation of the release of ADEA claims contained in the Release Agreement, and (ii) Employee’s compliance with the provisions of Section 5 below. Employee’s receipt of the Severance Payments and the extension of the exercise period of the vested option is further conditioned upon Employee not accepting full- or part-time employment with, or otherwise providing a material amount of consulting services to, any Competitor at any time prior to July 26, 2015.

If Employee becomes entitled to receive the Severance Payments upon satisfaction of the foregoing conditions, the Severance Payments shall begin on the first regularly scheduled payroll date determined by the Company to occur more than fifty-five (55) days from Employee’s date of Qualifying Termination (with any such base salary that otherwise would have been paid prior to such date to be payable in a lump sum on such payroll date.)

(e)Employee hereby agrees that the Change of Control Agreement dated May 31, 2013 ( the “COC Agreement”) by and between Employee and TETRA is hereby terminated and neither Employee nor TETRA shall have any further rights, liabilities or obligations under the COC Agreement or with respect to the termination thereof.

5.Restrictions and Obligations of Employee.

(a)Confidentiality. Employee acknowledges that the Company and its Affiliates have previously provided Employee with Confidential Information and will continue to provide Employee with Confidential Information during the Transition Period. Employee further acknowledges and agrees that the Company and its

Affiliates have put in place certain policies and practices to safeguard such Confidential Information, and that as a condition of his employment with the Company, Employee executed an Employment Agreement dated August 18, 2008 (the “Employment Agreement”) with the Company pursuant to which 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 and TETRA’s policies regarding Confidential Information. Employee agrees that he is subject to the obligations contained in the Employment Agreement to the extent such obligations continue after his termination of employment, including the confidentiality provisions therein, as well as the Company’s and TETRA’s policies and limitations on disclosure of Confidential Information. Employee further agrees that Employee 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 Employee’s own personal gain, any Confidential Information, except for such disclosures as required in the performance of Employee’s duties with the Company or any Affiliate or as may otherwise be required by law or legal process (in which case Employee 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). Employee acknowledges and agrees that such Confidential Information is the exclusive property of the Company and its Affiliates and will only be used for the benefit of the Company and its Affiliates.

(b)Non-Solicitation or Hire. For a two-year period following the termination of Employee’s employment with the Company or any Affiliate, Employee shall not, directly or indirectly (i) employ or seek to employ any person who is on the effective date of termination, or was at any time within the six-month period preceding the effective date of termination, an employee of the Company or any of its Affiliates or otherwise solicit, encourage, cause or induce any such employee of the Company or any of its Affiliates to terminate such employee’s employment with the Company or such Affiliate 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 or any Affiliate during such period) or (ii) take any action that would interfere with the relationship of the Company or its Affiliates with their suppliers or customers without, in either case, the prior written consent of the Company.

(c)Nondisparagement. Employee agrees not to make any statements or otherwise do anything that will disparage or damage the corporate, personal or professional reputation of the Company, its Affiliates and their respective officers, employees, managers or directors, as applicable.

(d)Injunctive Relief. Employee acknowledges that monetary damages for any breach of Section 5(a), (b) and (c) above will not be an adequate remedy and that irreparable injury will result to the Company, its Affiliates and their respective businesses in the event of such a breach. For that reason, Employee 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 Employee from violating such provisions.

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

(f)Termination of Severance Benefits. The provision of the Severance Benefits pursuant to Section 2(d) above is expressly conditioned upon Employee’s compliance with the foregoing provisions of this Section 5, including the continuing obligations under Employee’s Employment Agreement and the policies of the Company. Employee’s receipt of the Severance Payments and the extension of the exercise period of the vested option is further conditioned upon Employee not accepting full- or part-time employment with, or otherwise providing a material amount of consulting services to, any Competitor at any time prior to July 26, 2015. If at any time Employee shall (i) breach any of the provisions of this Section 5, including the continuing obligations under Employee’s Employment Agreement and the policies of the Company or TETRA, or (ii) become employed by, or otherwise provide a material amount of consulting services to, any Competitor at any time prior to July 26, 2015, then the Severance Payments

shall immediately terminate and the Company shall have no further obligation to pay any further Severance Payments pursuant to Section 2(d) and the extension of the exercise period for Employee’s vested options shall no longer be effective and such vested options shall be exercisable only for the applicable period following the effective date of termination in accordance with the respective option agreement and plan. If at any time before the acceleration of the vesting of the unvested shares of restricted stock awarded pursuant to the 2013 Award or the payment of the Unvested Equity Value the Employee shall (x) breach any of the provisions of this Section 5, including the continuing obligations under Employee’s Employment Agreement and the policies of the Company or TETRA, or (y) become employed by, or otherwise provide a material amount of consulting services to, any Competitor, then the 2013 Restricted Stock Benefits shall immediately terminate and there shall be no acceleration of vesting under the 2013 Award or payment of the Unvested Equity Value.
