SUBSIDIARY GUARANTY
THIS GUARANTY (this “Guaranty”) dated November 20, 2015 is made by the undersigned (each, a “Guarantor”), in favor of the holders from time to time of the Notes issued under the Note Purchase Agreement and any Supplement thereto, including each purchaser named in the Note Purchase Agreement and in any Supplement thereto, and their respective successors and assigns (collectively, the “Holders” and each individually, a “Holder”).
W I T N E S S E T H:


WHEREAS, TETRA TECHNOLOGIES, INC., a Delaware corporation (the “Company”), and the initial Holders have entered into a Note Purchase Agreement dated as of November 5, 2015 (the Note Purchase Agreement as amended, supplemented, restated or otherwise modified from time to time in accordance with its terms and in effect, the “Note Purchase Agreement”);
WHEREAS, pursuant to the Note Purchase Agreement, the Company has issued $125,000,000 principal amount of Series 2015 Notes;
WHEREAS, the Company directly or indirectly owns all or a substantial portion of the issued and outstanding Equity Interest of each Guarantor and, by virtue of such ownership and otherwise, such Guarantor will derive substantial benefits from the purchase by the Holders of the Company’s Notes;
WHEREAS, it is a condition precedent to the obligation of the Holders to purchase the Notes that each Guarantor shall have executed and delivered this Guaranty to the Holders and it is and will be a condition to the sale of Additional Notes that this Guaranty run in favor of the holders of such Additional Notes; and
WHEREAS, each Guarantor desires to execute and deliver this Guaranty to satisfy the conditions described in the preceding paragraph;
NOW, THEREFORE, in consideration of the premises and other benefits to each Guarantor and for other good and valuable consideration, the receipt and sufficiency of which are acknowledged, each Guarantor makes this Guaranty as follows:
SECTION 1.    Definitions.  Any capitalized terms not otherwise herein defined shall have the meanings attributed to them in the Note Purchase Agreement.
SECTION 2.    Guaranty.  Each Guarantor, jointly and severally with each other Guarantor, unconditionally and irrevocably guarantees to the Holders the due, prompt and complete payment by the Company of the principal of, make-whole amount, if any, other premium, if any, and interest on, and each other amount due under, the Notes or the Note Purchase Agreement and any Supplement thereto, when and as the same shall become due and payable (whether at stated maturity or by required or optional prepayment or by acceleration or otherwise) in accordance with the terms of the Notes, the Note Purchase Agreement and any Supplement thereto (the Notes, the Note Purchase Agreement and any Supplement being sometimes hereinafter collectively referred to as the “Applicable Note Documents” and the amounts payable by the Company under the Applicable Note Documents, and all other monetary obligations of the Company thereunder (including any attorneys’ fees and expenses), being sometimes collectively hereinafter referred to as the “Obligations”).  This Guaranty is a guaranty of payment and not just of collectibility and is in no way conditioned or contingent upon any attempt to collect from the Company or upon any other event, contingency or circumstance whatsoever.  If for any reason whatsoever the Company shall fail or be unable 

1






duly, punctually and fully to pay such amounts as and when the same shall become due and payable, each Guarantor, without demand, presentment, protest or notice of any kind, will forthwith pay or cause to be paid such amounts to the Holders under the terms of such Applicable Note Documents, in lawful money of the United States, at the place specified in the Note Purchase Agreement, or perform or comply with the same or cause the same to be performed or complied with, together with interest (to the extent provided for under such Applicable Note Documents) on any amount due and owing from the Company.  Each Guarantor, promptly after demand, will pay to the Holders the reasonable costs and expenses of collecting such amounts or otherwise enforcing this Guaranty, including, without limitation, the reasonable fees and expenses of counsel.  Notwithstanding the foregoing, the right of recovery against each Guarantor under this Guaranty is limited to the extent it is judicially determined with respect to any Guarantor that entering into this Guaranty would violate Section 548 of the United States Bankruptcy Code or any comparable provisions of any state law, in which case such Guarantor shall be liable under this Guaranty only for amounts aggregating up to the largest amount that would not render such Guarantor’s obligations hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any state law.
SECTION 3.    Guarantor’s Obligations Unconditional.  The obligations of each Guarantor under this Guaranty shall be primary, absolute and unconditional obligations of each Guarantor, shall not be subject to any counterclaim, set-off, deduction, diminution, abatement, recoupment, suspension, deferment, reduction or defense based upon any claim each Guarantor or any other person may have against the Company or any other person, and to the full extent permitted by applicable law shall remain in full force and effect without regard to, and shall not be released, discharged or in any way affected by, any circumstance or condition whatsoever (whether or not each Guarantor or the Company shall have any knowledge or notice thereof), including:
(a)any termination, amendment or modification of or deletion from or addition or supplement to or other change in any of the Applicable Note Documents or any other instrument or agreement applicable to any of the parties to any of the Applicable Note Documents;


(b)any furnishing or acceptance of any security, or any release of any security, for the Obligations, or the failure of any security or the failure of any person to perfect any interest in any collateral;


(c)any failure, omission or delay on the part of the Company to conform or comply with any term of any of the Applicable Note Documents or any other instrument or agreement referred to in paragraph (a) above, including, without limitation, failure to give notice to any Guarantor of the occurrence of a “Default” or an “Event of Default” under any Applicable Note Document;


(d)any waiver of the payment, performance or observance of any of the obligations, conditions, covenants or agreements contained in any Applicable Note Document, or any other waiver, consent, extension, indulgence, compromise, settlement, release or other action or inaction under or in respect of any of the Applicable Note Documents or any other instrument or agreement referred to in paragraph (a) above or any obligation or liability of the Company, or any exercise or non-exercise of any right, remedy, power or privilege under or in respect of any such instrument or agreement or any such obligation or liability;


(e)any failure, omission or delay on the part of any of the Holders to enforce, assert or exercise any right, power or remedy conferred on such Holder in this Guaranty, or any such failure, omission or delay on the part of such Holder in connection with any Applicable Note Document, or any other action on the part of such Holder;

2








(f)any voluntary or involuntary bankruptcy, insolvency, reorganization, arrangement, readjustment, assignment for the benefit of creditors, composition, receivership, conservatorship, custodianship, liquidation, marshaling of assets and liabilities or similar proceedings with respect to the Company, any other Guarantor or to any other person or any of their respective properties or creditors, or any action taken by any trustee or receiver or by any court in any such proceeding;


(g)any discharge, termination, cancellation, frustration, irregularity, invalidity or unenforceability, in whole or in part, of any of the Applicable Note Documents or any other agreement or instrument referred to in paragraph (a) above or any term hereof;


(h)any merger or consolidation of the Company or any Guarantor into or with any other Person, or any sale, lease or transfer of any of the assets of the Company or any Guarantor to any other person;


(i)any change in the ownership of any shares of Capital Stock of the Company or any change in the corporate relationship between the Company and any Guarantor, or any termination of such relationship;


(j)any release or discharge, by operation of law, of any other Guarantor from the performance or observance of any obligation, covenant or agreement contained in this Guaranty; or


(k)any other occurrence, circumstance, happening or event whatsoever, whether similar or dissimilar to the foregoing, whether foreseen or unforeseen, and any other circumstance which might otherwise constitute a legal or equitable defense (other than the defense of payment) or discharge of the liabilities of a guarantor or surety or which might otherwise limit recourse against any Guarantor.


SECTION 4.    Full Recourse Obligations.  The obligations of each Guarantor set forth herein constitute the full recourse obligations of such Guarantor enforceable against it (subject to the last sentence of Section 2) to the full extent of all its assets and properties.
SECTION 5.    Waiver.  Each Guarantor unconditionally waives, to the extent permitted by applicable law, (a) notice of any of the matters referred to in Section 3, (b) notice to such Guarantor of the incurrence of any of the Obligations, notice to such Guarantor or the Company of any breach or default by such Guarantor or the Company with respect to any of the Obligations or any other notice that may be required, by statute, rule of law or otherwise, to preserve any rights of the Holders against such Guarantor, (c) presentment to or demand of payment from the Company or the Guarantor with respect to any amount due under any Applicable Note Document or protest for nonpayment or dishonor, (d) any right to the enforcement, assertion or exercise by any of the Holders of any right, power, privilege or remedy conferred in the Note Purchase Agreement or any other Applicable Note Document or otherwise, (e) any requirement of diligence on the part of any of the Holders, (f) any requirement to exhaust any remedies or to mitigate the damages resulting from any default under any Applicable Note Document, (g) any notice of any sale, transfer or other disposition by any of the Holders of any right, title to or interest in the Note Purchase Agreement or in any other Applicable Note Document and (h) any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge, release (other than a release of such Guarantor herefrom pursuant to Section 1.2(b) of the Note Purchase Agreement) or defense of a guarantor or surety (other than the defense of payment) or which might otherwise limit recourse against such Guarantor.

SECTION 6.    Subrogation, Contribution, Reimbursement or Indemnity.  Until all Obligations have been indefeasibly paid in full, each Guarantor agrees not to take any action pursuant to any rights which may have arisen in connection with this Guaranty to be subrogated to any of the rights (whether contractual, under the United States Bankruptcy Code, as amended, including Section 509 thereof, under common law or otherwise) of any of the Holders against the Company or against any collateral security or guaranty or right of offset held by the Holders for the payment of the Obligations. Until all Obligations have been indefeasibly paid in full, each Guarantor agrees not to take any action pursuant to any contractual, common law, statutory or other rights of reimbursement, contribution, exoneration or indemnity (or any similar right) from or against the Company which may have arisen in connection with this Guaranty.  So long as any Obligations remain outstanding, if any amount shall be paid by or on behalf of the Company to any Guarantor on account of any of the rights waived in this Section 6, such amount shall be held by such Guarantor in trust, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Holders (duly endorsed by such Guarantor to the Holders, if required), to be applied against the Obligations, whether matured or unmatured, in such order as the Holders may determine.  The provisions of this Section 6 shall survive the term of this Guaranty and the payment in full of the Obligations.
SECTION 7.    Effect of Bankruptcy Proceedings, etc.  This Guaranty shall continue to be effective or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the sums due to any of the Holders pursuant to the terms of the Note Purchase Agreement or any other Applicable Note Document is rescinded or must otherwise be restored or returned by such Holder upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any other person, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to the Company or other person or any substantial part of its property, or otherwise, all as though such payment had not been made.  If an event permitting the acceleration of the maturity of the principal amount of the Notes shall at any time have occurred and be continuing, and such acceleration shall at such time be prevented by reason of the pendency against the Company or any other person of a case or proceeding under a bankruptcy or insolvency law, each Guarantor agrees that, for purposes of this Guaranty and its obligations hereunder, the maturity of the principal amount of the Notes and all other Obligations shall be deemed to have been accelerated with the same effect as if any Holder had accelerated the same in accordance with the terms of the Note Purchase Agreement or other Applicable Note Document, and such Guarantor shall forthwith pay such principal amount, make-whole amount, if any, other premium, if any, and interest thereon and any other amounts guaranteed hereunder without further notice or demand.
SECTION 8.    Term of Agreement.  This Guaranty and all guaranties, covenants and agreements of each Guarantor contained herein shall continue in full force and effect and shall not be discharged until such time as all of the Obligations shall be paid and performed in full and all of the agreements of such Guarantor hereunder shall be duly paid and performed in full; provided that each Guarantor shall be automatically and immediately released herefrom without any further act by any Person as provided in Section 1.2(b) of the Note Purchase Agreement.
SECTION 9.    Representations and Warranties.  Each Guarantor represents and warrants to each Holder that:
