$50,000,000 Senior Secured Notes due April 1, 2017

Dated as of March 18, 2015

TO EACH OF THE INITIAL PURCHASERS LISTED IN THE ATTACHED SCHEDULE A:

Ladies and Gentlemen:

TETRA TECHNOLOGIES, INC., a Delaware corporation (the “Company”), agrees with WELLS FARGO ENERGY CAPITAL, INC., in its capacity as noteholder representative for the Noteholders (in such capacity, “Noteholder Representative”), and with each Initial Purchaser party hereto (each Initial Purchaser may be referred to herein collectively as “you”), as follows:

1. AUTHORIZATION OF NOTES.

1.1. Description of Notes to be Initially Issued.

The Company has authorized the issue and sale of $50,000,000 aggregate principal amount of its Senior Secured Notes due April 1, 2017 (the “Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 13 of this Agreement). The Notes shall be substantially in the form set out in Exhibit 1.1, with such changes therefrom, if any, as may be approved by you and the Company. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement.

1.2. Subsidiary Guaranty.

The payment by the Company of all amounts due on or in respect to the Notes Obligations and the performance by the Company of its obligations under this Agreement will be guaranteed by each Subsidiary that (whether or not required by the terms of the Credit Agreement or other applicable documents governing such other Indebtedness) from time to time guarantees Indebtedness in respect of the Credit Agreement or any other Indebtedness in respect of borrowed money of the Company pursuant to the Subsidiary Guaranty in substantially the form of the attached Exhibit 1.2 (as it may be amended, restated, supplemented or otherwise modified from time to time, the “Subsidiary Guaranty”).

1.3. Security for the Notes Obligations.

The Company and each other Notes Party shall execute a Pledge and Security Agreement in substantially the form of Exhibit 1.3 attached hereto (as it may be amended, restated, supplemented or otherwise modified from time to time, the “Pledge and Security Agreement”), pursuant to which the Company and each other Notes Party shall pledge and grant a security interest in all of its right, title and interest in and to its Collateral in favor of the Noteholder Representative, for the benefit of the Noteholders, to secure the Notes Obligations.

1.4. Release of Subsidiary Guarantors.

Each Noteholder acknowledges and agrees that each Subsidiary Guarantor (other than any Compressco Unit Holding Subsidiary) shall be fully released and discharged from the Subsidiary Guaranty and Pledge and Security Agreement, and each Noteholder fully releases and discharges such Subsidiary Guarantor from the Subsidiary Guaranty and Pledge and Security Agreement, immediately and without any further act, upon such Subsidiary being released and discharged as guarantor under and in respect of the Credit Agreement; provided that (i) no Default or Event of Default exists or will exist immediately following such release and discharge; (ii) if any fee or other consideration is paid or given to any holder of Indebtedness under the Credit Agreement in connection with such release, other than the repayment of all or a portion of such Indebtedness under the Credit Agreement, each Noteholder receives equivalent consideration on a pro rata basis; and (iii) at the time of such release and discharge, the Company delivers to each Noteholder a certificate of a Responsible Officer certifying that such Subsidiary Guarantor has been or is being released and discharged as a guarantor under and in respect of the Credit Agreement and the matters set forth in clauses (i) and (ii).

2. THE NOTES.

2.1. Sale and Purchase of the Notes.

Subject to the terms and conditions of this Agreement, the Company will issue and sell to you, and you will purchase from the Company, at the Closing provided for in Section 3, Notes in the principal amount specified opposite your names in Schedule A at the purchase price of 100% of the principal amount thereof. Each Initial Purchaser’s obligations hereunder are several and not joint obligations and no Initial Purchaser shall have any liability to any Person for the performance or non-performance by any other Initial Purchaser hereunder.

2.2. Interest and Fees.

(a) Interest.

(i) The principal portion of each of the Notes shall be comprised entirely of LIBOR Tranches and Base Rate Tranches as the Company may request in accordance herewith.

(ii) Each principal portion of the Notes that constitutes a LIBOR Tranche shall bear interest at LIBOR for the Interest Period in effect for such Tranche plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate. Each principal portion of the Notes that constitutes a Base Rate Tranche shall bear interest at the Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(iii) Interest on each Note shall be paid in arrears on each Interest Payment Date. Interest shall also be paid on the date of any prepayment of Notes under Section 8 for the portion of the Notes so prepaid and upon payment (including prepayment) in full thereof and, during the existence of any Event of Default, interest shall be paid on demand of the Noteholder Representative.

(iv) Notwithstanding anything to the contrary contained herein, the Company shall pay interest (after, as well as before, entry of judgment thereon, to the extent permitted by law) on the principal amount of all outstanding Notes, at a rate per annum equal to the Default Rate (A) while any Event of Default under Section 11(a), Section 11(b), Section 11(g) or Section 11(h) exists and (B) if required by the Required Noteholders by notice to the Company given through the Noteholder Representative, while any Event of Default (other than an Event of Default referred to in the foregoing clause (A)) exists.

(v) All interest hereunder shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except that interest computed by reference to the Base Rate at times when the Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in

a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Base Rate or LIBOR shall be determined by the Noteholder Representative, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto.

(vi) If prior to the commencement of any Interest Period for a LIBOR Tranche, the Noteholder Representative determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining LIBOR for such Interest Period, then the Noteholder Representative shall give notice thereof to the Company and the Noteholders by telephone or facsimile as promptly as practicable thereafter and, until the Noteholder Representative notifies the Company and the Noteholders that the circumstances giving rise to such notice no longer exist, any Notice of Conversion/Continuation that requests the conversion of any Tranche to, or continuation of any Tranche as, a LIBOR Tranche shall be ineffective.

(vii) Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Noteholder to honor its obligation to maintain LIBOR Tranches either generally or having a particular Interest Period hereunder, then (A) such Noteholder shall promptly notify the Company and the Noteholder Representative thereof and such Noteholder’s obligation to maintain such LIBOR Tranches shall be suspended until such time as such Noteholder may again maintain such LIBOR Tranches and (B) if such Noteholder so requests by notice to the Company and the Noteholder Representative, all LIBOR Tranches then held by such Noteholder shall be automatically converted into Base Rate Tranches on the date specified by such Noteholder in such notice.

(viii) In the event of (A) the payment of any principal of any LIBOR Tranche other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (B) the conversion of any LIBOR Tranche into a Base Rate Tranche other than on the last day of the Interest Period applicable thereto (other than pursuant to Section 2.2(a)(vii)), or (C) the failure to issue, convert, continue or prepay any LIBOR Tranche on the date specified in any notice delivered pursuant hereto, then, in any such event, the Company shall compensate each Noteholder for the loss, cost and expense attributable to such event. A certificate of any Noteholder setting forth any amount or amounts that such Noteholder is entitled to receive pursuant to this clause (viii) shall be delivered to the Company and shall be conclusive absent manifest error. The Company shall pay such Noteholder the amount shown as due on any such certificate within ten (10) Business Days after receipt thereof.

(b) Follow-On Upfront Fees. The Company shall cause to be paid to the Noteholder Representative, for the ratable account of the Noteholders, upfront fees in an aggregate amount equal to 1.00% of the outstanding principal amount of the Notes on each of (i) January 1, 2016, and (ii) January 1, 2017, which fee shall be, in each case, payable on such date.

(c) Undrawn Commitment Fee. The Company shall cause to be paid to the Noteholder Representative, for the ratable account of the Initial Purchasers, commitment fees in an aggregate amount equal to 1.00% per annum on the Aggregate Commitments of the Initial Purchasers hereunder, which commitment fees shall accrue during the period from the date hereof to the earlier to occur of (i) the date of the Closing and (ii) the expiration of the Commitment Period, and which fee shall be payable on such earlier date; provided that no such commitment fees shall be payable in the event that the Closing does not occur on or prior to the expiration of the Commitment Period as a result of the Initial Purchasers electing not to purchase the Notes tendered by the Company at the Closing as a result of the Initial Purchasers’ determination that the condition precedent set forth in Section 4(m) hereof has not been satisfied.

2.3. Conversion and Continuation Elections.

(a) Each Tranche initially shall be of the Interest Rate Type specified in the Issuance Notice and, in the case of a LIBOR Tranche, shall have an initial Interest Period as specified in such Issuance Notice. Thereafter, during the period from Closing to the Maturity Date, the Company may, upon irrevocable written notice to the Noteholder Representative in accordance with Section 2.3(b): (i) elect, as of any Business Day, in the case of any Base Rate Tranche, or as of the last day of the applicable Interest Period, in the case of any LIBOR Tranche, to

convert any such Tranche into a Tranche of the other Interest Rate Type; or (ii) elect as of the last day of the applicable Interest Period, in the case of any LIBOR Tranche, to continue any Tranches having Interest Periods expiring on such day or to convert any Tranche into a Tranche with a different Interest Period.

(b) The Company shall deliver a Notice of Conversion/Continuation to be received by the Noteholder Representative not later than 12:00 noon (Houston, Texas time) at least (i) three (3) Business Days in advance of the Conversion/Continuation Date, if the applicable Tranches are to be converted into or continued as LIBOR Tranches; and (ii) one (1) Business Day in advance of the Conversion/Continuation Date, if the applicable Tranches are to be converted into Base Rate Tranches, specifying: (A) the proposed Conversion/Continuation Date; (B) the aggregate amount of Tranches to be converted or continued; (C) the Interest Rate Type of the Tranches resulting from the proposed conversion or continuation; and (D) in the case of conversions into LIBOR Tranches, the duration of the requested Interest Period (and, if any Notice of Conversion/Continuation in respect of any LIBOR Tranche does not specify an Interest Period, the Company shall be deemed to have selected an Interest Period of one month’s duration).

(c) If, upon the expiration of any Interest Period applicable to any LIBOR Tranche, the Company has failed to timely select a new Interest Period to be applicable to such LIBOR Tranche, or if any Default or Event of Default then exists, the Company shall be deemed to have elected to convert such LIBOR Tranche into a Base Rate Tranche effective as of the expiration date of such Interest Period.

(d) The Noteholder Representative will promptly notify each Noteholder of its receipt of a Notice of Conversion/Continuation or, if no timely notice is provided by the Company, the Noteholder Representative will promptly notify each Noteholder of the details of any automatic conversion. All conversions and continuations shall be made ratably according to the respective Noteholder’s Pro Rata Share of outstanding principal amounts of the Tranches with respect to which the notice was given.

(e) Notwithstanding anything to the contrary contained herein, each Tranche shall be an integral multiple of $5,000,000 and not less than $5,000,000, and at no time shall there be more than a total of three (3) LIBOR Tranches outstanding.

3. CLOSING.

3.1. Issuance Notice.

(a) The sale and purchase of all of the Notes to be purchased by you shall occur at a single closing (the “Closing”) upon the Company’s irrevocable written notice delivered to you on any Business Day prior to the expiration of the Commitment Period in the form of an Issuance Notice, which Issuance Notice must be received by you prior to 12:00 noon (Houston, Texas time) three (3) Business Days prior to the date of the proposed Closing.

(b) The Issuance Notice shall specify (i) the requested date of the Closing, which shall be a Business Day that falls within the Commitment Period, (ii) the Interest Rate Type of the Tranches that will be in place upon the initial purchase of the Notes, and (iii) with respect to any LIBOR Tranches, the duration of the Interest Period applicable to such Notes.

3.2. Issuance of the Notes.

If at the Closing the Company fails to tender such

Notes to you as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to your satisfaction, you shall, at your election, be relieved of all further obligations under this Agreement, without thereby waiving any rights you may have by reason of such failure or such nonfulfillment.

Subject to Section 17, without further written consent or authorization from Noteholders, Noteholder Representative, may execute any documents or instruments necessary to release any Lien encumbering any item of Collateral that is the subject of a sale or other disposition of assets permitted hereby or to which the Required Noteholders (or such other Noteholders as may be required to give such consent under Section 17) have otherwise consented.

(b) Rights and Duties as Collateral Agent.

Noteholders in its or their respective individual capacities unless the Required Noteholders shall otherwise agree in writing) shall be entitled, for the purpose of bidding and making settlement or payment of the purchase price for all or any portion of the Collateral sold at any such public sale, to use and apply any of the Notes Obligations arising under the Notes Documents as a credit on account of the purchase price payable by Noteholder Representative for any such Collateral at such sale. Each Noteholder and the Company acknowledges and agrees that Noteholder Representative is not a fiduciary for any Noteholder or for the Company, but simply is acting in the capacity described herein to alleviate administrative burdens for each Noteholder and the Company and that Noteholder Representative has no duties or responsibilities to any Noteholder or the Company except as expressly set forth in this Agreement.

23.3. Binding Effect.

Each Noteholder, by accepting the benefits of the Notes Documents, agrees that (a) any action taken by Noteholder Representative or the Required Noteholders (or, if expressly required hereby, a greater proportion of the holders of the Notes) in accordance with the provisions of this Agreement and the Notes Documents, (b) any action taken by Noteholder Representative in reliance upon the instructions of Required Noteholders (or, where so required, such greater proportion of the holders of the Notes) and (c) the exercise by Noteholder Representative or the Required Noteholders (or, where so required, such greater proportion of the holders of the Notes) of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all Noteholders.

(d) shall not have any duty to ascertain or to inquire as to the performance or observance of any provision of this Agreement or any other Notes Document, whether any condition set forth therein is satisfied or waived, as to the financial condition of the Company or as to the existence or continuation or possible occurrence or continuation of any Default or Event of Default and shall not be deemed to have notice or knowledge of such occurrence or continuation unless it has received a notice from the Company or any Noteholder describing such Default or Event of Default clearly labeled “notice of default” (in which case Noteholder Representative shall promptly give notice of such receipt to all Noteholders);

and, for each of the items set forth in clauses (a) through (d) above, each Noteholder hereby waives and agrees not to assert any right, claim or cause of action it might have against Noteholder Representative based thereon.

23.5. Noteholder Representative Individually.

Noteholder Representative and its Affiliates may make loans and other extensions of credit to, acquire Equity Interests of, or engage in any kind of business with, the Company or Affiliates thereof as though it were not acting as Noteholder Representative and may receive separate fees and other payments therefor. To the extent Noteholder Representative or any of its Affiliates makes any loan or otherwise becomes a Noteholder hereunder, it shall have and may exercise the same rights and powers hereunder and shall be subject to the same obligations and liabilities as any other Noteholder and the terms “Noteholder”, “Required Noteholders” and any similar terms shall, except where otherwise expressly provided in this Agreement or in any other Notes Document, include, without limitation, Noteholder Representative or such Affiliate, as the case may be, in its individual capacity as a Noteholder or as one of the Required Noteholders.

23.6. Noteholder Credit Decision.

Each Noteholder acknowledges that it shall, independently and without reliance upon Noteholder Representative, any other Noteholder or any of their Related Persons or upon any document (including any offering and disclosure materials in) solely or in part because such document was transmitted by Noteholder Representative or any of its Related Persons, conduct its own independent investigation of the financial condition and affairs of the Company and make and continue to make its own credit decisions in connection with entering into, and taking or not taking any action under, this Agreement or any other Notes Document or with respect to any transaction contemplated in this Agreement or any other Notes Document, in each case based on such documents and information as it shall deem appropriate. Except for documents expressly required by this Agreement or any other Notes Document to be transmitted by Noteholder Representative to Noteholders, Noteholder Representative shall not have any duty or responsibility to provide any Noteholder with any credit or other information concerning the business, prospects, operations, Property, financial and other condition or creditworthiness of the Company or any Affiliate thereof that may come in to the possession of Noteholder Representative or any of its Related Persons.

(b) Each Noteholder further agrees to indemnify Noteholder Representative and each of its Related Persons (to the extent not reimbursed by the Company), severally and ratably, from and against liabilities (including taxes, interests and penalties imposed for not properly withholding or backup withholding on payments made to or for the account of any Noteholder) that may be imposed on, incurred by or asserted against Noteholder Representative or any of its Related Persons in any matter relating to or arising out of, in connection with or as a result of this Agreement, any other Notes Document, any Senior Credit Document or any other act, event or transaction related, contemplated in or attendant to any such document, or, in each case, any action taken or omitted to be taken by Noteholder Representative or any of its Related Persons under or with respect to any of the foregoing; provided, however, that no Noteholder shall be liable to Noteholder Representative or any of its Related Persons to the extent such liability has resulted primarily from the gross negligence or willful misconduct of Noteholder Representative or, as the case may be, such Related Person, as determined by a court of competent jurisdiction in a final non-appealable judgment or order.
