Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

As previously announced on March 20, 2009, the Board of Directors of TETRA Technologies, Inc. (the “Company”) approved a succession plan under which Geoffrey M. Hertel, President and Chief Executive Officer of the Company, would resign from his positions as President and Chief Executive Officer immediately following the Company’s Annual Meeting of Stockholders on May 5, 2009, and Stuart M. Brightman would assume the positions of President and Chief Executive Officer. The Company also announced that it was the intention and expectation of the Board of Directors that the Company would enter into a transition agreement with Mr. Hertel.

On May 5, 2009, the Board of Directors of the Company approved a Transition Agreement between the Company and Mr. Hertel (the “Agreement”) in connection with Mr. Hertel’s resignation as the Company’s President and Chief Executive Officer. The Agreement, which was signed by the Company and Mr. Hertel on May 5, 2009, extends Mr. Hertel’s employment with the Company from May 5, 2009 through January 5, 2012 (the “Employment Period”), subject to earlier termination in accordance with the terms of the Agreement.

During the Employment Period, Mr. Hertel will provide such services to the Company as may be determined from time to time by the Board of Directors, and he will be subject to the supervision of the Company’s Chief Executive Officer. The Agreement also provides that during the Employment Period the Company shall (i) upon recommendation of the Nominating and Corporate Governance Committee of the Board of Directors, nominate Mr. Hertel as a director of the Company, and (ii) use commercially reasonable efforts to cause Mr. Hertel to be nominated to the board of directors of Compressco Partners GP Inc. and to serve as its Chairman.

As cash compensation for his services during the Employment Period, Mr. Hertel will receive a monthly base salary of $33,333, and he will be eligible to participate in all incentive, stock option, savings and retirement plans, practices, policies and programs generally available to the executive officers of the Company. For each calendar year ending during the employment period, Mr. Hertel will be eligible for an annual bonus on the same basis as the executive officers of the Company under the Company’s then current discretionary performance-based cash bonus program, and payment of the bonus, if awarded, will be made in a lump sum cash payment in accordance with the terms of the program. Target payout of the annual bonus will be $200,000 for each of the 2009 and 2010 calendar years, and $83,200 for the 2011 calendar year. Payout of the annual bonus is subject to Mr. Hertel’s continued employment during the period to which each bonus relates.  In the event a change in control (as defined in the Agreement) occurs on or before December 31, 2009, Mr. Hertel will be entitled to receive the target payout for the 2009 annual bonus, which will be payable within seven days following the change in control.

It is contemplated that Mr. Hertel’s duties as an employee of the Company will include assisting with the completion of an initial public offering by Compressco Partners, L.P. Under the Agreement, Mr. Hertel is eligible for an additional cash bonus of between $250,000 and $900,000 if the offering is closed on or before June 30, 2010, based on the market capitalization of Compressco Partners after the closing of the offering. Mr. Hertel is also eligible to receive bonuses based on the successful transitions of Mr. Brightman to the positions of President and Chief Executive Officer and Edwin H. Goldman to the position of Senior Vice President. Subject to the complete discretion of the Board of Directors based on its subjective evaluation of the success of the transition over two performance periods, Mr. Hertel may be eligible to receive cash bonuses of up to $200,000 in the aggregate for the period from May 5, 2009 until May 4, 2010, and $200,000 in the aggregate for the period from May 5, 2010 until May 4, 2011. Payout of the transition bonuses is subject to the continued employment of Messrs. Brightman and Goldman, respectively, during the period to which each bonus relates. In the event a change in control

1

 occurs on or before May 4, 2010 and Mr. Brightman and/or Mr. Goldman remain employed by the Company immediately prior to the change of control, the payment of all or a portion of the initial transition bonus will be accelerated and payable within seven days following the change in control.

Mr. Hertel’s employment shall automatically terminate upon his death and may be terminated by the Company in the event of his “disability” (as defined in the Agreement) during the Employment Period. In addition, Mr. Hertel may terminate his employment with the Company for “Good Reason,” as specified in the Agreement, or for any other reason upon 30 days’ advance notice. The Agreement defines “Good Reason” as (i) any failure by the Company to comply with the compensation provisions of the Agreement other than an isolated, insubstantial and inadvertent failure; (ii) the Company requiring Mr. Hertel to be based at any office or location other than the Company’s headquarters in The Woodlands, Texas; (iii) any purported termination by the Company of Mr. Hertel’s employment other than as expressly permitted by the Agreement; or (iv) any failure by the Company to require the Agreement to be assumed by any successor of the Company.

The Agreement also provides that Mr. Hertel’s employment may be terminated by the Company for “Cause,” as specified in the Agreement. “Cause” is defined as (i) the willful and continued failure of Mr. Hertel to perform substantially his duties and obligations under the Agreement (for reasons other than injury, illness or incapacity) after a written demand for such performance is provided by the Company; (ii) Mr. Hertel’s conviction or the entry of a plea of guilty or nolo contendre to a misdemeanor involving moral turpitude or a felony; (iii) fraud, theft, embezzlement or a similar misappropriation of funds or property of the Company or its affiliates; or (iv) the willful engagement in illegal conduct or gross misconduct which is materially injurious to the Company or its affiliates.

If Mr. Hertel’s employment terminates as a result of his death, if the Company terminates Mr. Hertel’s employment as a result of his disability or other than for Cause, or if Mr. Hertel terminates his employment for “Good Reason,” then (i) the Company shall continue to pay his base salary through the end of the Employment Period; (ii) the Company shall pay an amount equal to any bonus that would have been payable as a result of the initial public offering of Compressco Partners as if his employment had not been terminated; (iii) the Company shall pay an amount equal to any Transition Bonus that would have been payable as if Mr. Hertel’s employment had not been terminated; (iv) Mr. Hertel or his heirs will continue to be eligible to participate in welfare benefit plans; and (v) the Company shall pay any business expenses which have been incurred through the date of termination in accordance with the Company’s policies. If at any time following the termination of Mr. Hertel’s employment and during the noncompetition period thereafter he breaches any of the nondisclosure, noncompetition and nonsolicitation provisions provided for under the Agreement, the Company will no longer be obligated to make the foregoing payments.

If the Company terminates Mr. Hertel’s employment for “Cause,” Mr. Hertel will only be entitled to receive payment of his base salary through the date of termination and any deferred compensation or other employee benefits which he is otherwise entitled to receive. If Mr. Hertel terminates his employment for any reason other than “Good Reason,” Mr. Hertel will be entitled to receive (i) his base salary through the date of termination; (ii) the payment of any business expenses incurred but not reimbursed through the date of termination; and (iii) the payment of any deferred compensation or other employee benefits which he is entitled to receive.

The Agreement includes nondisclosure, noncompetition, and non-solicitation provisions binding on Mr. Hertel during the Employment Period and for a period of three years after his Separation of Service under the Agreement.

TRANSITION AGREEMENT

THIS TRANSITION AGREEMENT (this “Agreement”) is entered into effective as of May 5, 2009 (the “Effective Date”), by and among TETRA TECHNOLOGIES, INC., a Delaware corporation (the “Company”) and GEOFFREY M. HERTEL (the “Employee”).

WHEREAS, the Employee has been employed by the Company in various capacities since 1993, most recently serving as its President and Chief Executive Officer;

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.Employment.

1.1The Company hereby agrees to continue to employ the Employee, and the Employee hereby agrees to accept continued employment with the Company, 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 on January 5, 2012 (the “Employment Period”).  

2.Duties.

2.2In addition to the foregoing description of the Employee’s duties, during the Employment Period the Company shall, if so recommended by the Nominating and Corporate Governance Committee (the “Governance Committee”) of the Board, (i) nominate and recommend the Employee for membership on the Board, and (ii) use commercially reasonable efforts to cause the Employee to be nominated and recommended for membership on the board of directors of Compressco Partners GP Inc. (“Compressco GP”), the general partner of Compressco Partners, L.P.

Employment Period and on a basis consistent with other directors after the Employment Period, serve as a member of the Board and as a member of the board of directors of Compressco GP.

2.3During the Employment Period, the Employee agrees to devote such time as reasonably required to carry out and perform the responsibilities assigned to the Employee hereunder.  Notwithstanding the foregoing, during the Employment Period it shall not be a violation of this Agreement for the Employee (i) to serve on industry-related, civic or charitable boards or committees, (ii) with the approval of the Company’s Governance Committee and the Board, to serve on other corporate boards or committees, and (iii) to continue to own and manage his personal investments including, without limitation, his current oil and gas interests as described on Exhibit A attached hereto and incorporated herein and, with the approval of the Board, invest in, acquire and/or manage additional oil and gas interests, so long as any activities described in clauses (i), (ii) and (iii) do not significantly interfere with the performance of the Employee’s responsibilities as an employee of the Company in accordance with this Agreement and, in the case of the activities described in clause (ii), will not, in the good faith judgment of the Board, constitute an actual or potential conflict of interest with the business activities of the Company or its affiliated companies.  It is expressly understood and agreed that to the extent that any such activities have been conducted by the Employee prior to the date hereof, the continued conduct of such activities (or the conduct of activities similar in nature and scope thereto) subsequent to the date hereof shall not thereafter be deemed to interfere with the performance of the Employee’s responsibilities to the Company.

(a)During the Employment Period, the Employee shall be eligible for an annual bonus (the “Annual Bonus”) for each calendar year ending during the Employment Period (calendar years ending December 31, 2009, 2010 and 2011) on the same basis as other executive officers under the Company’s then current discretionary performance-based cash bonus program (or its successor), which shall be payable in accordance with the terms of such program.  The Employee’s target payout for the Annual Bonus will be $200,000 for the 2009 and 2010 calendar years and $83,200 for the 2011 calendar year.  Payment of the Annual Bonus, if awarded, will be made in a lump sum cash payment in accordance with the terms of the Company’s discretionary

2

performance-based cash bonus program (or its successor) but in no event earlier than January 1 of, and no later than March 31 of the calendar year immediately following the calendar year in respect of which the Annual Bonus is awarded.  Except as otherwise expressly provided in Section 5 hereof, any Annual Bonus payable under this Section 3.2 shall not be payable unless the Employee is employed by the Company on the last day of the period to which such Annual Bonus relates.

(b)Notwithstanding the foregoing, in the event a Change in Control (as herein defined) occurs  on or before December 31, 2009, Employee shall be entitled to receive the target payout for the Annual Bonus for 2009.  Any payment of the 2009 Annual Bonus pursuant to this Section 3.2(b) shall be made within 7 calendar days of the effective date of the Change in Control.  The foregoing shall only apply to a Change in Control that occurs on or before December 31, 2009.  In the event a Change in Control occurs during the Employment Period and after December 31, 2009, the Employee’s right to receive any Annual Bonus hereunder shall remain subject to the discretion of the Board and satisfaction of any applicable performance criteria.

(c)For purposes of this Agreement, a “Change in Control” shall be deemed to have occurred upon any of the following events:

(i)any “person” (as defined in Section 3(a)(9) of the Securities Exchange Act of 1934 (the “Exchange Act”), and as modified in Section 13(d) and 14(d) of the Exchange Act) other than (A) the Company or any of its subsidiaries, (B) any employee benefit plan of the Company or any of its subsidiaries, (C) any entity controlled by the Company, (D) a company owned, directly or indirectly, by stockholders of the Company in substantially the same proportions as their ownership of the Company, or (E) an underwriter temporarily holding securities pursuant to an offering of such securities ( a “Person”), becomes the “beneficial owner” (as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of securities of the Company representing more than 50% of the shares of voting stock of the Company then outstanding;

(ii)the consummation of any merger, organization, 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

(v)individuals who, as of the Effective Date, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the Effective Date whose election by the Board, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but 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 Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) if the foregoing definition of “Change in Control” were to apply, but would not be so subject if the term “Change in Control” were defined herein to mean a “change in control event” within the meaning of Treasury Regulation § 1.409A-3(i)(5), then “Change in Control” shall mean a “change in control event” within the meaning of Treasury Regulation § 1.409A-3(i)(5), but only to the extent necessary to prevent such compensation from becoming subject to the income tax under Section 409A of the Code

3.3Compressco IPO Bonus.

(a)It is contemplated that the duties of the Employee hereunder will include assisting the Company and Compressco GP and Compressco Partners, in completing an initial public offering by Compressco Partners.  If on or before June 30, 2010 Compressco Partners shall complete the Compressco IPO (as herein defined), Employee shall be entitled to a cash bonus (the “Compressco IPO Bonus”) from the Company in the applicable amount set forth below based upon the Market Capitalization (as herein defined) of Compressco Partners:

If Mr. Brightman or Mr. Goldman are not employed by the Company immediately prior to the Change in Control, then Employee shall have no further right to receive the applicable Transition Bonuses.

The foregoing provisions of this Section 3.4(c) shall only be applicable to a Change in Control occurring on or before May 4, 2010. In the event the Change in Control shall occur at any subsequent time during the Employment Period, the Employee’s right to receive any Transition Bonus shall remain subject to the complete discretion of the Board and the Compensation Committee, taking into consideration such factors as they may deem relevant.

3.5Employee Benefits.

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

4.2Disability.  If the Company determines in good faith that a Disability of the Employee has occurred during the Employment Period (pursuant to the definition of Disability set forth below), the Company may give to the Employee written notice of its 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 by the Employee (the “Disability Effective Date”), provided that within the thirty (30) day period after such receipt, the Employee shall not have returned to full-time performance of the Employee’s duties. For purposes of this Agreement, “Disability” shall mean and be deemed to have occurred if (i) the Employee is receiving 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 an aggregate of 180 days within any given period of 360 consecutive days.

4.3Termination by the Company.  The Company may terminate the Employee’s employment during the Employment Period for Cause.  For purposes of this Agreement, “Cause” shall mean:

(a)the willful and continued failure of the Employee to perform substantially the Employee’s duties and obligations hereunder (other than any such failure resulting from bodily injury or disease or any other incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to the Employee by the Chief Executive Officer or the Board which specifically identifies the manner in which the Chief Executive Officer or the Board believes that the Employee has not substantially performed the Employee’s duties;

(b)Employee’s conviction by a court of competent jurisdiction, or entry of a plea of guilty or nolo contendere, to a misdemeanor involving moral turpitude or a felony;

(c)fraud, theft, embezzlement or similar misappropriation of funds or property of the Company or its affiliated companies; or

7

(d)the willful engaging by the Employee in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company and/or its affiliated companies, monetarily or otherwise.

For purposes of this provision, no act, or failure to act, on the part of the Employee shall be considered “willful” unless it is done, or omitted to be done, by the Employee in bad faith or without reasonable belief that the Employee’s action or omission was in the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board or upon the instructions of the Chief Executive Officer or based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by the Employee in good faith and in the best interests of the Company and its affiliated companies.

4.4Termination by Employee.  The Employee may terminate his employment during the Employment Period for (i) Good Reason, or (ii) for any other reason, in the sole discretion of the Employee, upon 30 days’ advance written notice to the Company.

For purposes of this Agreement, “Good Reason” shall mean, without Employee’s written consent, any one of the following:

(a)any failure by the Company to comply with any of the provisions of Section 3 of this Agreement, other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Employee;

(b)any requirement for the Employee to be based at any office or location other than as provided in Section 2.4;

(c)any purported termination by the Company of the Employee’s employment otherwise than as expressly permitted by this Agreement; or

(d)any failure by the Company to comply with and satisfy Section 10.3 of this Agreement.

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) 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 Date of Termination (as herein defined); provided, however, that notwithstanding any provision in this Agreement to the contrary, a Notice of Termination given in connection with a termination for Good Reason shall be given by the Employee within a reasonable period of time, not to exceed 30 days, following the occurrence of the event giving rise to such right of termination.  The failure by the Employee or the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Disability, Cause or Good Reason shall not waive any right of the Employee or the Company hereunder or

8

preclude the Employee or the Company from asserting such fact or circumstance in enforcing the Employee’s or the Company’s rights hereunder.

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

(a)if the Employee’s employment is terminated as a result of the Employee’s death, the date of the Employee’s death;

(b)if the Employee’s employment is terminated because of the Employee’s Disability, the Disability Effective Date;

6.Confidential Information.

Employee acknowledges that during the course of his employment with the Company since 1993 and in his services as a director of the Company since 1984, 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 Employee’s employment or service as a director of the Company, is developed, designed or discovered or otherwise acquired or learned by 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.  Confidential Information includes, by way of example and without limitation, the following:  all patents,

11

inventions, processes and formulae including any proprietary information regarding existing and proposed products and services; information regarding existing and potential customers, employees, contractors, and the industry not generally known to the public; strategies, books, records and documents; the names of and other information concerning customers, investors, and business affiliates such as contact name, service or product provided, pricing for that customer, type and amount of products and services used, credit and financial data, and/or other information relating to the relationship with that customer; plans and strategies for expansion or acquisition; budgets, financial and sales data, pricing and costing data; sources of capacity and sources of supply; contracts benefiting or obligating the Company or its affiliated companies; bids or proposals submitted to or by any third parties; organizational structure; personnel information, including salaries and responsibilities of personnel; payment amounts or rates paid to consultants or other service providers; and other confidential or proprietary information.

7.Nondisclosure.

Employee acknowledges and agrees that the Company and its affiliated companies have put in place certain policies and practices to safeguard such Confidential Information.  Employee further acknowledges and agrees that such Confidential Information constitutes a valuable, special and unique asset used by the Company and its affiliated companies in their businesses to obtain a competitive advantage over their competitors and was and is developed or acquired by the Company and its affiliated companies at considerable time and expense and is intended to be used solely for the benefit of the Company and its affiliated companies.  Employee also acknowledges and agrees that except for the Employee’s previous agreements to maintain the confidentiality of such Confidential Information as set forth in that certain Agreement dated February 26, 1993 between the Company and the Employee (the “Prior Agreement”) and the Employee’s agreements contained in this Agreement, the Company would not impart or provide access to such Confidential Information to Employee.  Accordingly, Employee agrees that during Employee’s lifetime, both during and after the term of Employee’s employment with the Company, unless authorized by the Board in writing, 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 the event Employee becomes legally compelled to disclose any Confidential Information, Employee will provide the Company with prompt written notice so that the Company may seek a protective order or other appropriate remedy with respect to such disclosure.  Employee further acknowledges and agrees that the Company’s conduct in providing Employee with Confidential Information in exchange for the Employee’s nondisclosure agreement gives rise to the Company’s interest in restraining Employee from competing against the Company as set forth in Section 8 and Section 9 hereof, and that Employee’s agreement to those provisions is designed to enforce Employee’s nondisclosure agreement.

8.Noncompetition.

8.1Employee acknowledges and agrees that his training, work and experience with the Company and its affiliated companies will enhance his value to competitors, and that the nature of the Confidential Information to which Employee has access will make it difficult, if not impossible for Employee to work for any person or entity that competes with the business of the Company and its affiliated companies without disclosing or utilizing the Confidential Information to which Employee has access during the course of Employee’s employment or term as a director of the Company.  Employee further acknowledges that the Company and its affiliated companies are principally engaged in the business as described in Section 8.2 below and that the Company and its affiliated companies provide products and services to customers throughout the United States of America and in international markets.  Employee further acknowledges and agrees that the Company’s agreement to provide Employee with access to its Confidential Information is ancillary to and contingent upon Employee’s agreement that Employee will not, unless authorized by the Board in writing, during the term of his employment by the Company and for a period of three years immediately following the Employee’s Separation Date (collectively, the “Noncompete Period”), directly or indirectly:

(a)carry on, initiate or have any ownership interest in any business that services, manufactures or distributes products or services similar to those of the Company or its affiliated companies or that otherwise competes with the Company or its affiliated companies in any geographic area or market where the Company or any of its affiliated companies are conducting business as of the Separation Date or have conducted business during the previous twelve (12) months, provided that this Section 8.1(a) shall not apply to the ownership by Employee of less than 5% of the outstanding shares of a publicly-held entity that has shares listed for trading on a securities exchange registered with the SEC or through the automated quotation system of a registered securities association;

(c)contact, solicit, or divert, for the purpose of attempting to enter into a business relationship related to the manufacture, distribution or servicing of products or services manufactured, distributed, or provided by Company or its affiliated companies,successors or assigns, with any customer with whom the Company has had a contractual or business relationship during the two-year period prior to the Separation Date.
