Ladies and Gentlemen:

TETRA TECHNOLOGIES, INC., a Delaware corporation (the “Company”), agrees with you as follows:


1.	AUTHORIZATION OF NOTES.

1.1Description of Notes Initially Issued.

Pursuant to the Note Purchase Agreement dated as of November 5, 2015 (the “Original Note Purchase Agreement”), the Company has authorized the issue and sale of $125,000,000 aggregate principal amount of its 11.00% Senior Notes due November 5, 2022 (as so amended hereby, the “Series 2015 Notes”, the Series 2015 Notes together with each Series of Additional Notes that may be from time to time issued pursuant to Section 2.2 below, the “Notes”, such term to include any such notes issued in substitution therefor pursuant to Section 13 of this Agreement). The Notes issued under the Original Note Purchase Agreement have been issued substantially in the form of Exhibit 1.1 of the Original Note Purchase Agreement, and any other Notes or replacement Notes shall be substantially in the form set out in Exhibit 1.1 hereof. The Company and the holder of the Notes wish to amend and restate the Original Note Purchase Agreement to provide security for the Notes and to provide for the other modifications specified herein. 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.

1.2Subsidiary Guaranty; Release.

(a)Subsidiary Guaranty. The payment by the Company of all amounts due on or in respect to the Notes and the performance by the Company of its obligations under this Agreement will be guaranteed by each Subsidiary that (regardless of whether required by the terms of the Credit Agreement or other applicable documents governing other Indebtedness of the Company) 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 or supplemented from time to time (the “Subsidiary Guaranty”).

(b)Release of Subsidiary Guarantors. Each holder of a Note acknowledges and agrees that each Subsidiary Guarantor shall be fully released and discharged from the Subsidiary Guaranty and the Security Agreement, and each holder of a Note fully releases and discharges such Subsidiary Guarantor from the Subsidiary Guaranty and the 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 in excess of 0.50% of the outstanding principal amount of such Indebtedness is paid or given to any holder of any 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 holder of a Note receives equivalent consideration on a pro rata basis; and (iii) at the time of such release and discharge,

the Company delivers to each holder of Notes 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); provided further, that if the consideration referred to in clause (ii) above exceeds 0.50% of the outstanding principal amount of the Indebtedness under the Credit Agreement, the release and discharge of such Subsidiary Guarantor from the Subsidiary Guaranty and the Security Agreement shall only occur upon the consent of each of the holders of the Notes and each holder of a Note shall receive equivalent consideration on a pro rata basis.

1.3Security for the Notes Obligations.

The Company and each Affiliated Grantor shall execute a 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 “Security Agreement”) and other Collateral Documents, pursuant to which the Company and each Affiliated Grantor shall pledge and grant a security interest in all of its right, title and interest in and to its Collateral for your benefit to secure the Company’s obligations under this Agreement.

This Agreement and the other Note Documents have been duly authorized by all necessary corporate or partnership action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

The Subsidiary Guaranty has been duly authorized by all necessary corporate, partnership or limited liability company action (as the case may be) on the part of each Subsidiary Guarantor and upon execution and delivery thereof will constitute the legal, valid and binding obligation of each Subsidiary Guarantor, enforceable against each Subsidiary Guarantor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, fraudulent transfer, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Each of the Security Agreement and the other Collateral Documents has been duly authorized by all necessary corporate, partnership or limited liability company action (as the case may be) on the part of each Affiliated Grantor and upon execution and delivery thereof will constitute the legal, valid and binding obligation of each Affiliated Grantor, enforceable against each Affiliated Grantor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, fraudulent transfer, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

The written information provided to you and each Other Purchaser, along with the reports filed by the Company with the Securities and Exchange Commission, fairly describes, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries. Except as disclosed in Schedule 5.3, this Agreement, the documents, certificates or other writings delivered to you by or on behalf of the Company in connection with the transactions contemplated hereby and the financial statements listed in Schedule 5.5 (this Agreement and such documents, certificates or other writings and such financial statements delivered to each Purchaser being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made; provided that with respect to projected financial information and any forecasts of financial performance, the Company makes no representation or warranty that such projections or forecasts will ultimately prove to have been accurate, and the Company represents only that such information was prepared in good faith based upon (i) assumptions believed to be reasonable at the time and (ii) the best information available to the Company and its Restricted Subsidiaries, in each case, as of the date of delivery and the Restatement Date. Except as expressly described in Schedule 5.3, or in one of the documents, certificates or other writings identified therein, or in the financial statements listed in Schedule 5.5, since the date of the most recent audited financial statements required to be filed with the Securities Exchange Commission as part of the Company’s Form 10-K, there has been no change in the financial condition, operations, business or properties of the Company or any Subsidiary except changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. There is no Material non-public information known to the Company that could reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the other documents, certificates and other writings delivered to you by or on behalf of the Company specifically for use in connection with the transactions contemplated hereby.

5.4Organization and Ownership of Shares of Subsidiaries; Affiliates.

(a)Schedule 5.4 contains (except as noted therein) complete and correct lists of: (i) the Company’s Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization, and the percentage of shares of each class of its Capital Stock outstanding owned by the Company and each

(b)All of the outstanding shares of Capital Stock of each Subsidiary shown in Schedule 5.4 as being owned by the Company and its Subsidiaries have been validly issued, are fully paid and nonassessable and are owned by the Company or another Subsidiary free and clear of any Lien (except as otherwise disclosed in Schedule 5.4 and except with respect to foreign Subsidiaries that individually or in the aggregate are not Material and the consequence of which would not in the aggregate result in a Material Adverse Effect).

(c)Each Subsidiary identified in Schedule 5.4 is a corporation or other legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority to own or hold under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact.

(d)No Restricted Subsidiary is a party to, or otherwise subject to, any legal restriction or any agreement (other than this Agreement or any other Note Document, the agreements listed on Schedule 5.4 and customary limitations imposed by corporate, partnership or limited liability company law statutes) restricting the ability of such Restricted Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Company or any of its Restricted Subsidiaries that owns outstanding shares of Capital Stock of such Restricted Subsidiary, except legal restrictions or agreements by foreign Subsidiaries that individually or in the aggregate are not Material and the consequence of which would not in the aggregate result in a Material Adverse Effect.

(d)Deferral Pending Disposition. The obligation of the Company to prepay Notes pursuant to the offers required by paragraph (a) and accepted in accordance with paragraph (b) of this Section 8.4 is subject to the consummation of the Disposition in respect of which such offers and acceptances shall have been made.

8.6Maturity; Surrender, etc.

In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount or other premium, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest, Make-Whole Amount, if any, and other premium, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full, after such payment and upon the written request of the Company, shall be surrendered to the Company and canceled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

8.7Purchase of Notes.

The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to an offer to purchase made by the Company or an Affiliate pro rata to the holders of any series of Notes at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information reasonably determined by the Company to enable it to make an informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 50% of the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by the Company or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

8.8Make-Whole Amount.

The term “Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments through the third anniversary of the Original Closing Date with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or 8.3, if applicable, or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

“Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon and premium that would be due after the Settlement Date and on or before the third anniversary of the Original Closing Date with respect to such Called Principal if the Called Principal were prepaid on such third anniversary in accordance with Section 8.2, provided that if such Settlement Date is not a date on which interest payments are due to be made under the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.5 or Section 12.1.

“Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or 8.3, if applicable, or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

Subject to Sections 10.6 and 10.7, the Company will at all times preserve and keep in full force and effect the corporate, partnership or limited liability company existence of each of its Restricted Subsidiaries and Non-Recourse Pledgors (unless merged into the Company or a Restricted Subsidiary, or solely in the case of a Non-Recourse Pledgor, another Non-Recourse Pledgor) and all rights and franchises of the Company, its Restricted Subsidiaries and the Non-Recourse Pledgors unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate, partnership or limited liability company existence, right or franchise could not, individually or in the aggregate, have a Material Adverse Effect.

(c)Dispositions (other than Material Dispositions) not otherwise permitted by Section 10.7(a) or Section 10.7(b); provided that:

(i)the aggregate net book value of all assets disposed of in any fiscal year pursuant to this Section 10.7(c) does not exceed the greater of (A) 15% of Consolidated Total Assets as of the end of the immediately preceding fiscal year or (B) $50,000,000;

Notwithstanding the foregoing provisions of this Section 10.7, the Company may, or may permit any Restricted Subsidiary to, make a Disposition (other than a Material Disposition) and the assets subject to such Disposition shall not be subject to or included in any of the foregoing limitations or the computation contained in Section 10.7(c) of the preceding sentence if the net proceeds from such Disposition are within 365 days of such Disposition:

(d)reinvested in productive assets used in carrying on the business of the Company and its Restricted Subsidiaries; or

(e)applied to the payment or prepayment of the Notes or of any other Senior Indebtedness.

Any prepayment of Notes pursuant to the foregoing provisions of this Section 10.7 shall be in accordance with Sections 8.2 or 8.5, as applicable, without regard to the minimum prepayment requirements of Section 8.2 or 8.5, as applicable, if such proceeds are less than such minimum.

Notwithstanding the foregoing provisions of this Section 10.7, and in addition to the other provisions applicable to Dispositions, the Company shall not nor shall it permit any Subsidiary to consummate any Material Disposition unless: (i) not less than five Business Days prior to consummating such Material Disposition, the Company gives notice of such Material Disposition to each holder of Notes; (ii) in the case of a Material Disposition other than a Disposition of Compressco Units, the consideration for such Disposition is at least 75% cash; (iii) such Material Disposition is for a price not less than the Fair Market Value of the assets that are the subject of such Material Disposition, as certified in a resolution of the Board of Directors of the Company; and (iv) the Company makes an offer to prepay the Notes in accordance with Section 8.4 with the Net Available Cash, if any, received by the Company, any Restricted Subsidiary or any Non-Recourse Pledgor from such Material Disposition.

If any Subject Indebtedness permits the Company to apply cash proceeds from a Material Disposition to the retirement of other Indebtedness rather than to the retirement of such Subject Indebtedness, the Company shall apply the portion of such cash proceeds constituting Net Available Cash from such Material Disposition to offer to prepay the Notes in accordance with Section 8.4 prior to application of any such cash proceeds to the retirement of such Subject Indebtedness.

(b)the Company may not designate a Subsidiary Guarantor as an Unrestricted Subsidiary;

(c)notwithstanding Section 10.5(h), if an Unrestricted Subsidiary is designated as a Restricted Subsidiary, all outstanding Indebtedness and Liens of such Subsidiary shall be deemed to have been incurred as of the date of such designation; and

(d)if a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 10.11 or under one or more clauses of the definition of Permitted Investments, as determined by the Company, provided that designation will only be permitted if the Investment would be permitted at the time pursuant to Section 10.11 and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

10.9Nature of Business.

The Company will not, and will not permit any Restricted Subsidiary to, engage in any business if, as a result, the general nature of the business in which the Company and its Restricted Subsidiaries, taken as a whole, would then be engaged would be substantially changed from the general nature of the business in which the Company and its Subsidiaries, taken as a whole, are engaged on the Restatement Date as described in the Disclosure Documents.

(iv)no Default or Event of Default has occurred and is continuing.

(b)The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 10.10(a) hereof:

17.	AMENDMENT AND WAIVER.

17.1Requirements.

This Agreement and the other Note Documents may be amended, and the observance of any term hereof, of any Supplement or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company (and the Subsidiary Guarantors, in the case of the Subsidiary Guaranty and the Security Agreement, and the Non-Recourse Pledgors, in the case of the Security Agreement) and the Required Holders, except that no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest or of the Make-Whole Amount or other premium on, the Notes, (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver, or (iii) amend this Section 17.1; provided, that any amendment or waiver of the Collateral Documents shall be subject to the required consent of the lenders under the Credit Agreement.

17.2Solicitation of Holders of Notes.

(a)Solicitation. The Company will provide each holder of the Notes (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof, of any Supplement or of the Notes. The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the requisite holders of Notes.

(b)Payment. The Company will not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of Notes as consideration for or as an inducement to the entering into by any holder of Notes of any waiver or amendment of any of the terms and provisions hereof or of any Supplement unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms, ratably to each holder of Notes then outstanding even if such holder did not consent to such waiver or amendment.

(c)Consent in Contemplation of Transfer. Any consent made pursuant to this Section 17.2 by the holder of any Note that has transferred or has agreed to transfer such Note to the Company, any Subsidiary or any Affiliate of the Company and has provided or has agreed to provide such written consent as a condition to such transfer shall be void and of no force or effect except solely as to such holder, and any amendments

effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Notes that were acquired under the same or similar conditions) shall be void and of no force or effect except solely as to such transferring holder.

17.3Binding Effect, etc.

Any amendment or waiver consented to as provided in this Section 17 applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note nor any delay in exercising any rights hereunder, under any Supplement or under any Note shall operate as a waiver of any rights of any holder of such Note. As used herein, the term “this Agreement” or “the Agreement” and references thereto shall mean this Agreement as it may from time to time be amended or supplemented.

17.4Notes held by Company, etc.

Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding.

(c)The Company consents to process being served in any suit, action or proceeding solely of the nature referred to in Section 22.2(a) by mailing a copy thereof by registered or certified or priority mail, postage prepaid, return receipt requested, or delivering a copy thereof in the manner for delivery of notices specified in Section 19, to it.

22.5Construction.

Each covenant contained herein or in any Supplement shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein or in any Supplement, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant.

thereof, then such provision shall be interpreted on the basis of GAAP as in effect and applied immediately before such change shall have become effective until such notice shall have been withdrawn or such provision amended in accordance herewith.

Each of the parties hereto agrees as follows:

(a) this Agreement (including all Exhibits and Schedules) shall amend, restate and replace in its entirety the Original Note Purchase Agreement (including all exhibits and schedules attached thereto) on the Restatement Date, and the Original Note Purchase Agreement (including all exhibits and schedules attached thereto) shall thereafter be of no further force and effect, except (i) for the purpose of incorporating by reference certain identified defined terms and other provisions from the Original Note Purchase Agreement in this Agreement, (ii) to evidence the incurrence by the Company of the obligations under the Original Note Purchase Agreement, without regard to whether such obligations are contingent as of the Restatement Date, and (iii) to evidence the representations and warranties made by the Company and the Subsidiary Guarantors prior to the Restatement Date (which representations and warranties shall not be superseded or rendered ineffective by this Agreement as they pertain to the period prior to the Restatement Date);

(e) this amendment and restatement of the Original Note Purchase Agreement shall be limited as written and not be a consent to any other amendment, restatement, supplement, waiver or other modification of any other provisions under any Note Documents, without regard to whether similar, and, except as expressly provided herein or in any other Note Document, all terms and conditions of the Note Documents remain in full force and effect unless otherwise specifically amended hereby.
