WARRANT AGREEMENT

Exhibit 4.1

WARRANT AGREEMENT

This WARRANT AGREEMENT (“Warrant Agreement”) is entered into as of December 14, 2016, by and between TETRA Technologies, Inc., a Delaware corporation (the “Company”) and Computershare Trust Company, N.A., a federally chartered trust company (the “Warrant Agent”).

WHEREAS, the Company is engaged in a public offering (the “Public Offering”) of shares of common stock of the Company, par value $0.01 per share (the “Common Stock”), and warrants (each a “Warrant” or, collectively, the “Warrants”) entitling holders to purchase shares of Common Stock (the “Warrant Shares”);

WHEREAS, the shares of Common Stock and the Warrants will be sold in combination, with one warrant to purchase one share of Common Stock accompanying every two shares of Common Stock sold. The shares of Common Stock and the Warrants are immediately separable and will be issued separately;

WHEREAS, the Company has filed, with the Securities and Exchange Commission, a registration statement on Form S-3 (Registration No. 333-310335), as amended (the “Registration Statement”), for the registration, under the Securities Act of 1933, as amended (the “Act”), of, among other securities, the Warrants and the Warrant Shares;

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange and exercise of the Warrants;

WHEREAS, the Company desires to provide for the form, terms and provisions of the Warrants, including the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights and immunities of the Company, the Warrant Agent and the holders of the Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided herein, the legally valid and binding obligations of the Company, and to authorize the execution and delivery of this Warrant Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1.    APPOINTMENT OF WARRANT AGENT.

The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the express terms and conditions set forth in this Warrant Agreement (and no implied terms or conditions).

2.    WARRANTS.

(a)    Book-Entry Warrant Certificates. The Warrants shall initially be issuable in book-entry registration only and evidenced by one or more warrant certificates in global form (the “Book-Entry Warrant Certificates”). All of the Warrants shall initially be represented by one or more Book-Entry Warrant Certificates deposited with the Depository Trust Company (“Depository”) and registered in the name of Cede & Co., as nominee of the Depository. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the Depository or its nominee for each Book-Entry Warrant Certificate or (ii) institutions that have accounts with the Depository (such institutions, with respect to a Warrant in its account, each a “Participant”). If the Depository subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to each Holder a warrant certificate in substantially the form of Exhibit A hereto (a “Warrant Certificate”), the provisions of which are incorporated herein and signed by, or bear the facsimile signature of, an authorized signatory. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

(b)    Effect of Countersignature. Unless and until countersigned by the Warrant Agent by facsimile or electronic signature pursuant to this Warrant Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

(c)    Registration.

(i)    Warrant Register. The Warrant Agent shall maintain a register (the “Warrant Register”) for the registration of the original issuance and transfers of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with the written instructions delivered to the Warrant Agent by the Company.

(ii)    Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (“Registered Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

2

(d)    Terms and Exercise of Warrants.

(i)    Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $5.75 per share of Common Stock, subject to the adjustments provided in Section 4 hereof. The term “Warrant Price” as used in this Warrant Agreement refers to the price per whole share at which shares of Common Stock may be purchased at the time such Warrant is exercised.

(ii)    Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the date of original issuance and terminating at 5:00 p.m., New York City time, on December 14, 2021 (five years following the closing date of the Public Offering) (“Expiration Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Warrant Agreement shall cease at the close of business on the Expiration Date. Subject to Section 10(h), the Company may extend the duration of the Warrants by delaying the Expiration Date; provided, however, that the Company will provide notice of not less than 20 days to Registered Holders of such extension and that such extension shall be identical in duration among all of the then outstanding Warrants.

(iii)    Exercise of Warrants.

(A)    Payment. Subject to the provisions of the Warrant and this Warrant Agreement, a Warrant, when countersigned by the Warrant Agent, may be exercised by the Registered Holder thereof by surrendering it at the office of the Warrant Agent (or its successor) designated for such purposes (or, in the case of a global Book-Entry Certificate, properly delivered by the Participant in accordance with the Depository’s procedures), currently being:

Computershare Trust Company, N.A.

250 Royall Street

Canton, Massachusetts 02021

Attention: Client Administration Corporate Actions

with the subscription form, as set forth in the Warrant, duly executed, and by paying in full, in lawful money of the United States (or pursuant to the cashless exercise procedure specified in Section 2(d)(iv) below, if such cashless exercise procedure is applicable), by certified or bank cashier’s check payable to the order of the Warrant Agent or by wire transfer to the Warrant Agent’s bank account designated by it, the Warrant Price for each whole Warrant Share as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the Warrant Shares, and the issuance of the Warrant Shares. The Warrant Agent shall forward funds received for warrant exercises in a given month by the 5th Business Day of the following month by wire transfer to an account designated by the Company.

3

(B)    Fractional Shares. Notwithstanding any provision to the contrary contained in this Warrant Agreement, the Company shall not be required to issue any fraction of a Warrant Share in connection with the exercise of Warrants, and in any case where the Registered Holder would be entitled under the terms of the Warrants to receive a fraction of a Warrant Share upon the exercise of such Registered Holder’s Warrants, issue or cause to be issued only the largest whole number of Warrant Shares issuable on such exercise (and such fraction of a Warrant Share will be disregarded); provided, that if more than one Warrant Certificate is presented for exercise at the same time by the same Registered Holder, the number of whole Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares issuable on exercise of all such Warrants.

(C)    Reliance by Warrant Agent. Whenever a payment for fractional Warrants Shares is to be made by the Warrant Agent hereunder, the Company shall (i) promptly prepare and deliver to the Warrant Agent a certificate setting forth in reasonable detail the facts related to such payments and the prices and formulas utilized in calculating such payments, and (ii) provide sufficient monies to the Warrant Agent in the form of fully collected funds to make such payments. The Warrant Agent shall be fully protected in relying upon such a certificate and shall have no duty with respect to, and shall not be deemed to have knowledge of, any payment for fractional Warrant Shares under any section of this Warrant Agreement relating to the payment of fractional Warrant Shares unless and until the Warrant Agent shall have received such a certificate and sufficient monies.

(iv)    Cashless Exercise. If an effective registration statement is available for the issuance of the Warrant Shares (as determined by the Company in its sole discretion), then the Warrants may only be exercised, in whole or in part, at such time by means of a cash exercise specified in Section 2(d)(iii)(A). If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the Warrant Shares to the Registered Holders (as determined by the Company in its sole discretion), then the Warrants may only be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Registered Holders shall be entitled to receive that number of Warrant Shares equal to the quotient obtained by dividing (A-B) (X) by (A), where:

4

(v)    As used herein,

“VWAP Trading Day” means a day on which (i) there is no VWAP Market Disruption Event (as defined below) and (ii) trading in the Common Stock generally occurs on the New York Stock Exchange or, if the Common Stock is not then listed on the New York Stock Exchange, on the other principal U.S. national or regional securities exchange on which the Common Stock is then listed, or, if the Common Stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Common Stock is then traded. If the Common Stock (or any other security for which a daily volume-weighted average price must be determined) is not so listed or traded, then “VWAP Trading Day” means a “Business Day.”

“VWAP Market Disruption Event” means (i) a failure by the principal U.S. national or regional securities exchange or market on which the Common Stock is listed or admitted for trading to open for trading during its regular trading session or (ii) on any scheduled VWAP Trading Day for the Common Stock, the occurrence or existence prior to 1:00 p.m., New York City time, for more than a one half-hour period in the aggregate during regular trading hours, of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in the Common Stock or in any options, contracts or futures contracts relating to the Common Stock.

The Company will be responsible for determining whether cashless exercise applies to a Warrant exercise and will notify the Warrant Agent if it does. The Company shall calculate and transmit to the Warrant Agent, and the Warrant Agent shall have no obligation under this Section to calculate, the number of Warrant Shares issuable in connection with the cashless exercise. The number of shares of Common Stock to be issued on such exercise will be determined by the Company (with written notice thereof to the Warrant Agent) using the formula set forth in Section 2(d)(iv), and the Warrant Agent shall have no duty or obligation to investigate or confirm whether the Company’s determination of the number of shares of Common Stock to be issued on such exercise, pursuant to Section 2(d)(iv), is accurate or correct. The Warrant Agent will promptly return the Warrant Price paid by the Registered Holder in the event a cashless exercise applies.

(vi)    Issuance of Certificates. No later than three (3) Business Days following the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price, the Company shall issue to the Registered Holder of such Warrant a certificate or certificates

5

representing (or deliver electronically through the facilities of the Depository Trust Corporation) the number of full shares of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and, if such Warrant shall not have been exercised or surrendered in full (provided that the Registered Holder has delivered the original physical Warrant Certificate to the Warrant Agent, which delivery shall not include delivery of a notice from the Depository of the transfer or exercise of Warrants in the form of a global Book-Entry Warrant Certificate), a new countersigned Warrant for the number of shares as to which such Warrant shall not have been exercised or surrendered. If fewer than all of the Warrants evidenced by a global Book-Entry Warrant Certificate are exercised, a notation shall be made to the records maintained by the Depository, its nominee for each global Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise. Warrants may not be exercised by, or securities issued to, any Registered Holder in any state in which such exercise or issuance would be unlawful. In the event such exercise would be unlawful with respect to a Registered Holder in any state, the Registered Holder shall not be entitled to exercise such Warrants and such Warrants may have no value and expire worthless.

The Warrant Agent shall have no obligation under this Warrant Agreement to calculate, the aforementioned quotient. The number of shares of Common Stock to be issued on such cashless exercise will be determined by the company (with written notice thereof to the Warrant Agent) using the formula set forth above and the Warrant Agent shall have no duty or obligation to investigate or confirm whether the Company’s determination of the number of shares of Common Stock to be issued on such exercise, pursuant to written agreement, is accurate or correct.

(vii)    Valid Issuance. All shares of Common Stock issued upon the proper exercise or surrender of a Warrant in conformity with this Warrant Agreement shall be validly issued, fully paid and non-assessable.

(viii)    Date of Issuance. Each person or entity in whose name any such certificate for shares of Common Stock is issued or to whom shares of Common Stock are credited to such person’s or entity’s account at the Depository shall, for all purposes, be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate or the date such shares of Common Stock are credited to such person’s or entity’s account, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open.

3.    ADJUSTMENTS.

(a)    Stock Dividends, Splits. If, after the date hereof the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or otherwise affected by a forward or reverse split of shares of Common Stock, or other similar event, then, on the effective date of such stock dividend, split or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased or decreased in proportion to such increase or decrease in outstanding shares of Common Stock.

6

(b)    Aggregation of Shares. If, after the date hereof, the number of outstanding shares of Common Stock is decreased by a consolidation, combination or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

(c)    Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in Sections 3(a) and 3(b) above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price, immediately prior to such adjustment, by a fraction, (a) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (b) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

(d)    Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares issuable upon exercise of a Warrant (each, an “Adjustment Event”), the Company shall give reasonable written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Section 3(a), 3(b) or 3(c), the Company shall give written notice to each Registered Holder, at the last address set forth for such Registered Holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event. The Warrant Agent shall have no obligation under any Section of this Warrant Agreement to determine whether an Adjustment Event has occurred or to calculate any of the adjustments set forth herein.

(e)    Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 3, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Warrant Agreement. However, the Company may, at any time, in its sole discretion, make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

(f)    Calculations. All calculations under this Section 3 shall be made by rounding to the nearest cent or 1/100th of a share, as applicable.

4.    RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 3 above, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other

7

securities, property, options, evidence of indebtedness or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of any Warrant, then, in each such case, each Registered Holder shall be entitled to participate in such Distribution to the same extent that such Registered Holder would have participated therein if such Registered Holder had held the number of shares of Common Stock acquirable upon complete exercise of any Warrant (without regard to any limitations or restrictions on exercise of any Warrant) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution.

5.    FUNDAMENTAL TRANSACTIONS.

(a)    Fundamental Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity assumes in writing all of the obligations of the Company under this Warrant Agreement in accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance reasonably satisfactory to the Registered Holder, including agreements to deliver to the Registered Holder in exchange for any Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to such Warrant, including, without limitation, which is exercisable for a corresponding number of shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of any Warrant (without regard to any limitations on the exercise of any Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital stock, such adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of the Warrant immediately prior to the consummation of such Fundamental Transaction). Upon the consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of the applicable Fundamental Transaction, the provisions of the Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under the Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of each Fundamental Transaction, the Successor Entity shall deliver to the Registered Holder confirmation that there shall be issued upon exercise of the Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under Section 3 above, which shall continue to be receivable thereafter)) issuable upon the exercise of the Warrant prior to the applicable Fundamental Transaction, such shares of publicly traded common stock or equivalent equity security of the Successor Entity (including its Parent Entity) which the Registered Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had the Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of the Warrant), as adjusted in accordance with the provisions of this Warrant Agreement. Notwithstanding the foregoing, the Registered Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 5(a) to permit the Fundamental Transaction

8

without the assumption of this Warrant Agreement. In addition to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to insure that the Registered Holder will thereafter have the right to receive upon an exercise of the Warrant at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of Common Stock (or other securities, cash, assets or other property (except such items still issuable under Section 3 above, which shall continue to be receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental Transaction, such shares, stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) (collectively, the “Corporate Event Consideration”) which the Registered Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction had the Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of the Warrant).

(b)    Change of Control Provisions.

(i)    Holder Optional Change of Control Provisions. Notwithstanding the foregoing and the provisions of Section 5(a) above, at the request of the Registered Holder delivered at any time commencing on the earliest to occur of (A) the public disclosure of any Change of Control, (B) the consummation of any Change of Control and (C) the Registered Holder of the Warrant first becoming aware of any Change of Control through the date that is ninety (90) days after the public disclosure of the consummation of such Change of Control by the Company pursuant to a Current Report on Form 8-K filed with the SEC, the Company or the Successor Entity (as the case may be) shall exchange the Warrant for consideration equal to the Holder Black Scholes Value of such portion of the Warrant subject to exchange (collectively, the “Aggregate Holder Black Scholes Value”) in the form of, at the Company’s election (such election to pay in cash or by delivery of the Rights (as defined below), a “Consideration Election”), either (I) rights (collectively, the “Rights”), convertible in whole, or in part, at any time, without the requirement to pay any additional consideration, at the option of the Registered Holder, into such Corporate Event Consideration applicable to such Change of Control equal in value to the Aggregate Holder Black Scholes Value (with the aggregate number of Successor Shares (as defined below) issuable upon conversion of the Rights to be determined in increments of 10% of the portion of the Aggregate Holder Black Scholes Value attributable to such Successor Shares (the “Successor Share Value Increment”), with the aggregate number of Successor Shares issuable upon exercise of the Rights with respect to the first Successor Share Value Increment determined based on 95% of the Closing Bid Price of the Successor Shares on the date the Rights are issued and on each of the nine (9) subsequent VWAP Trading Days, in each case, the aggregate number of additional Successor Shares issuable upon exercise of the Rights shall be determined based upon a Successor Share Value Increment at 95% of the Closing Bid Price of the Successor Shares in effect for such corresponding VWAP Trading Day (such ten (10) VWAP Trading Day period commencing on, and including, the date the Rights are issued, the “Rights Measuring Period”), or (II) in cash, subject to the last sentence of this section; provided, that the Company shall not consummate a Change of Control if (x) the Corporate Event Consideration includes capital stock or other equity interests (the “Successor Shares”) either in an entity that is not listed on an Eligible Market or an entity in which the daily share

9

volume for the applicable Successor Shares for each of the twenty (20) VWAP Trading Days prior to the date of consummation of such Change of Control is less than the aggregate number of Successor Shares issuable to the Registered Holder upon conversion in full of the applicable Rights (without regard to any limitations on conversion therein, assuming the exercise in full of the Rights on the date of issuance of the Rights and assuming the Closing Bid Price of the Successor Shares for each VWAP Trading Day in the Rights Measuring Period is the Closing Bid Price on the VWAP Trading Day ended immediately prior to the time of consummation of the Change of Control) and (y) the Company shall not have properly elected in accordance with this Section 5(b) to pay the applicable Holder Black Scholes Value to the Registered Holder in cash. The Company shall give the Registered Holder written notice of each Consideration Election at least twenty (20) VWAP Trading Days prior to the time of consummation of such Change of Control. Payment of such amounts or delivery of the Rights, as applicable, shall be made by the Company (or at the Company’s direction) to the Registered Holder on the later of (x) the second (2nd) VWAP Trading Day after the date of such request and (y) the date of consummation of such Change of Control (or, with respect to any Right, if applicable, such later time that holders of Common Stock are initially entitled to receive Corporate Event Consideration with respect to the shares of Common Stock of such holder). Any Corporate Event Consideration included in the Right, if any, pursuant to this Section 5(b)(i) is pari passu with the Corporate Event Consideration to be paid to holders of shares of Common Stock, and the Company shall not permit a payment of any Corporate Event Consideration to the holders of shares of Common Stock without on or prior to such time delivering the Right to the Registered Holder hereunder. The Company shall not include cash in any Corporate Event Consideration (whether payable to the holders of shares of Common Stock or pursuant to the Right, as applicable) or pursuant to clause (II) above, if the Senior Indebtedness or amounts thereunder are then outstanding, unless the Senior Indebtedness has first been satisfied (including, without limitation, by the Company’s election to repay or redeem such Senior Indebtedness and, in the case of a revolving credit facility, all commitments having been terminated or expired, and all letters of credit issued thereunder having expired or been terminated without any pending draw thereunder) or consents or waivers for such cash have been granted thereunder.

(ii)    Company Optional Change of Control Redemption. Notwithstanding the foregoing and the provisions of Section 5(a) above, the Company shall have the right, with prior written notice delivered to the Registered Holder, not more than twenty (20) VWAP Trading Days and not less than ten (10) VWAP Trading Days prior to the time of consummation of the Change of Control, to redeem all, but not less than all, of the Warrant at a price in cash equal to the Company Black Scholes Value for the Warrant. Payment of such amounts shall be made by the Company (or at the Company’s direction) to the Registered Holder on the date of consummation of such Change of Control (the “Redemption Date”). Notwithstanding anything herein to the contrary, at any time prior to the later of (x) the time such Company Black Scholes Value has been paid in full to the Registered Holder in cash and (y) the Redemption Date, the Warrant may be exercised, in whole or in part, by the Registered Holder into shares of Common Stock pursuant to Section 2 and the Company Black Scholes Value to be paid on the Redemption Date shall be adjusted accordingly. For the avoidance of doubt, (A) if both the Company and the Registered Holder elect to effect a redemption pursuant to this Section 5(b), the redemption pursuant to Section 5(b)(i) shall govern such Change of Control and (B) the Company may only elect to effect a redemption pursuant to this Section 5(b)(ii) if the Company Black Scholes Value is to be paid in cash.

10

(c)    Application. The provisions of this Section 5 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events and shall be applied as if the Warrant (and any such subsequent warrants) were fully exercisable and without regard to any limitations on the exercise of the Warrant.

6.    NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Restated Certificate of Incorporation, Amended and Restated Bylaws or other organizational documents or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Registered Holder. Without limiting the generality of the foregoing, the Company (a) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, and (b) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable shares of Common Stock upon the exercise of this Warrant. Notwithstanding anything herein to the contrary, if after the sixty (60) calendar day anniversary of the Issuance Date, the Registered Holder is not permitted to exercise this Warrant in full for any reason, the Company shall use its best efforts to promptly remedy such failure, including, without limitation, obtaining such consents or approvals as necessary to permit such exercise into shares of Common Stock.

7.    TRANSFER AND EXCHANGE OF WARRANTS.

(a)    Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant into the Warrant Register, upon surrender of such Warrant for transfer, duly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time at the Company’s expense and upon the Company’s written request.

(b)    Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants.

(c)    Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate for a fraction of a Warrant.

(d)    Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

(e)    Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Warrant

11

Agreement, the Warrants required to be issued pursuant to the provisions of this Section 7, and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

8.    OTHER PROVISIONS RELATING TO RIGHTS OF REGISTERED HOLDERS OF WARRANTS.

(a)    No Rights as Stockholder. Except as provided in Section 4 with respect to rights to distributions, a Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to exercise any preemptive rights, to vote or to consent on any matter, or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter.

(b)    Lost, Stolen Mutilated or Destroyed Warrants. If any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor and date as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone. The Company or the Warrant Agent may request reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto and an open penalty surety bond satisfactory to it and holding the Warrant Agent and the Company harmless, absent notice to the Warrant Agent that such certificates have been acquired by a bona fide purchaser. The Warrant Agent may, at its option, issue replacement Warrants for mutilated certificates upon presentation thereof without such indemnity.

(c)    Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement. The Company will take all such commercially reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the trading market upon which the Common Stock may be listed.

9.    CONCERNING THE WARRANT AGENT AND OTHER MATTERS.

(a)    Payment of Taxes.

WARRANT

THIS WARRANT CERTIFIES THAT, for value received [●], or registered agents, is the registered holder of a Warrant or Warrants (the “Warrant”) expiring on a date which is five years from the original date of issuance on December 14, 2016, to purchase [●] fully paid and non-assessable shares of common stock, par value $0.01 per share (the “Shares”), of TETRA TECHNOLOGIES, INC., a Delaware corporation (the “Company”), for each Warrant evidenced by this Warrant Certificate. This Warrant Certificate is subject to and shall be interpreted under the terms and conditions of the Warrant Agreement (as defined below).

The Warrant entitles the holder thereof to purchase from the Company, commencing upon the original issuance of the Warrant on December 14, 2016, such number of Shares at the price of $5.75 per share (the “Warrant Price”), upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or agency of Computershare Trust Company, N.A. (the “Warrant Agent”), such payment to be made by check made payable to the Warrant Agent or by wire transfer to the Warrant Agent’s bank account designated by it (or pursuant to the cashless exercise procedure specified in Section 2(d)(iii) of the Warrant Agreement, if such cashless exercise procedure is applicable, but only subject to the conditions set forth herein and in the Warrant Agreement, dated December 14, 2016, between the Company and the Warrant Agent (the “Warrant Agreement”). In the event of any conflict between the terms of this Warrant Certificate and the terms of the Warrant Agreement, the terms of the Warrant Agreement shall govern. The Warrant Agreement provides that, upon the occurrence of certain events, the Warrant Price and the number of Warrant Shares purchasable hereunder, set forth on the face hereof, may be adjusted, subject to certain conditions. The term Warrant Price as used in this Warrant Certificate refers to the price per Share at which Shares may be purchased at the time the Warrant is exercised.

This Warrant will expire on the date first referenced above if it is not exercised prior to such date by the registered holder pursuant to the terms of the Warrant Agreement or if it is redeemed by the Company prior to such date as described below.

No fraction of a Share will be issued upon any exercise of a Warrant. If, upon exercise of a Warrant, a holder would be entitled to receive a fractional interest in a Share, the Company will, upon exercise, issue or cause to be issued only the largest whole number of Shares issuable on such exercise (and such fraction of a Share will be disregarded).

Upon any exercise of the Warrant for less than the total number of full Shares provided for herein, there shall be issued to the registered holder(s) hereof or its assignee(s) a new Warrant Certificate covering the number of Shares for which the Warrant has not been exercised.

Warrant Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder(s) hereof in person or by attorney duly authorized in writing, may be exchanged in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants.

A-2

Upon due presentment for registration of transfer of the Warrant Certificate at the office or agency of the Warrant Agent, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any applicable tax or other governmental charge.

The Company and the Warrant Agent may deem and treat the registered holder(s) as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone) for the purpose of any exercise hereof, of any distribution to the registered holder(s), and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

Except as provided in the Warrant Agreement, this Warrant does not entitle the registered holder(s) to any of the rights of a stockholder of the Company.
