(c)    Subject to the provisions of the Transition Services Agreement and Co-Employer Agreement, Buyer shall be responsible for providing the notices and making available COBRA continuation coverage for all Employees and their respective covered dependents whose qualifying events (as defined in Code Section 4980B) occur after the Closing Date.

From and after the Closing Date, any right to reemployment for any Employee who is on short-term or long-term disability as of immediately prior to the Closing Date shall be the obligation of Buyer and its Affiliates (including the Companies) and not of the Sellers and their Affiliates, so long as such reemployment occurs within the longer of (i) 180 days of the Closing Date and (ii) any statutorily prescribed period during which such Employee is entitled to reemployment.

Buyer agrees to file or cause to be filed in a timely manner all necessary documents (including, but not limited to, all Tax Returns) with respect to all such amounts. The Parties agree that the transaction qualifies as an occasional sale (or similar exemption) under applicable state Law and agree to file all Tax Returns consistent with such position. The Parties also agree to timely provide any certifications necessary in connection with such position. The Parties further agree to cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Transfer Taxes.

Section 7.4    336(e) Election.

(a)    The Parties understand and agree that the acquisition of the TSB Shares will be treated as an asset sale for federal income Tax purposes pursuant to Code Section 336(e). Accordingly, the Company shall make a timely election under Code Section 336(e) (and any corresponding election under state, local and foreign tax law) with respect to the purchase and sale of the TSB Shares (collectively, the “336(e) Election”). TETRA will include any income, gain, loss, deduction, or other tax item resulting from the 336(e) Election on its on its consolidated federal income Tax Return to the extent required by applicable Law.

TETRA will timely furnish to the Buyer a copy of the election statement described in Treasury Regulation 1.336-2(h)(3)(iii) (the “Section 336(e) Election Statement”), and TETRA Applied will file such Section 336(e) Election Statement with its Tax Return for the taxable year that includes the Closing. Buyer shall deliver to TETRA all information reasonably requested by TETRA in connection with the preparation of the Section 336(e) Election Statement.

(c)    In accordance with the 336(e) Election, Buyer and TETRA shall agree on the allocation of the Tax Consideration attributable to TETRA Applied among the assets of TETRA Applied which shall be made, adjusted, and amended, in accordance with Code Section 336(e), the Treasury Regulations promulgated thereunder, and Section 2.4 (the “Section 336(e) Purchase Price Allocation”).

(d)    Each of the Parties agrees to (i) prepare and timely file all applicable income Tax Returns in a manner consistent with the Section 336(e) Purchase Price Allocation as finalized, (ii) file Form 8883 or any successor form(s) in accordance therewith, and (iii) otherwise act in accordance with the Section 336(e) Purchase Price Allocation, unless otherwise required by applicable Law, (iv) promptly inform the other Parties in writing of any challenge by any Taxing Authority related to the 336(e) Election and to consult and keep one another informed with respect to the status of any such challenge, provided, however, that no Party shall be unreasonably impeded in its ability and discretion to negotiate, compromise and/or settle any tax audit, claim or similar proceedings in connection with such 336(e) Purchase Price Allocation.

Section 7.5    Tax Covenants

(a)    For purposes of determining whether and to what extent a Liability for Taxes for a Straddle Period constitutes Companies Taxes, the portion of any Tax that is allocable will be determined as though the taxable year of each Company terminated at the close of business on the Closing Date; provided, however, that with respect to Property Taxes relating to the assets of the Companies, the Buyer shall be responsible for all 2018 Property Taxes.

(b)    %3. TETRA shall timely file all Tax Returns of the Companies due on or before the Closing Date or that otherwise relate solely to Tax periods ending on or before the Closing Date and that are due after the Closing Date and Sellers shall timely pay any Taxes shown as due and owing on such Tax Returns. TETRA shall deliver to Buyer for Buyer’s review and comment a copy of each such Tax Return prior to the due date thereof (taking into account any extensions). TETRA will reasonably consider all comments received from Buyer with respect to such Tax Returns.

(i)    Buyer shall prepare in a manner consistent with past practice all Tax Returns of the Companies for a Straddle Period that are required to be filed after the Closing Date. Buyer shall deliver to TETRA for TETRA’s review and comment a copy of each such Tax Return at least thirty (30) days

prior to the due date thereof (taking into account any extensions), Buyer will (A) incorporate all reasonable comments from TETRA with respect to the portion of the Straddle Period that is on or before the Closing Date, and (B) incorporate all reasonable comments from TETRA with respect to the portion of the Straddle Period that is on or after the Closing Date, unless Buyer disputes any such comments. Buyer and TETRA will promptly attempt to resolve any disputes with respect to any comments from TETRA; provided, that if they are unable to do so within five (5) days prior to the due date of such Tax Returns, the filings will be made as proposed by TETRA with respect to a pre-Closing period comment and as proposed by Buyer with respect to a post-Closing period comment, and such disputed items will be further resolved through amendments to the Tax Returns. Buyer shall timely file all such Tax Returns and shall timely pay Taxes shown as due and owing thereon.

(ii)    Buyer shall promptly, and in no event later than fifteen (15) days, reimburse Sellers for any Taxes (other than Companies Taxes) paid by Sellers pursuant to this Section 7.5(b). Sellers shall promptly, and in no event later than fifteen (15) days, reimburse Buyer for any Companies Taxes paid by Buyer pursuant to this Section 7.5(b).

(c)    Buyer, on the one hand, and Sellers, on the other hand, shall promptly notify each other upon receipt by such Party of written notice of any inquiries, claims, assessments, audits or similar events with respect to Taxes relating to a Pre-Closing Tax Period (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”). Any failure to so notify the other Party of any Tax Matter shall not relieve such other Party of any liability with respect to such Tax Matters except to the extent such Party was actually and materially prejudiced as a result thereof. TETRA shall have sole control of the conduct of all Tax Matters relating exclusively to a Tax period ending on or before the Closing Date; provided, however, that TETRA shall keep Buyer reasonably informed of the progress of any such Tax Matter.

(d)    In the case of a Tax Matter relating exclusively to a Straddle Period, Sellers and Buyer shall jointly control all proceedings taken in connection with any such Tax Matter including any settlement or compromise thereof; provided, however, that neither Sellers on one hand nor Buyer on the other hand shall effect any such settlement or compromise without obtaining the other's prior written consent thereto, which shall not be unreasonably conditioned, withheld or delayed. Buyer shall have sole control of the conduct of all Tax Matters that do not relate to a Pre-Closing Tax Period or Straddle Period, including any settlement or compromise thereof.

(e)    Sellers shall be entitled to the amount of any refund or credit of Taxes of the Companies with respect to a Pre-Closing Tax Period (to the extent such Taxes were paid by the Companies prior to the Closing), which refund or credit is actually recognized by Buyer or its Affiliates (including the Companies) within one year after the Closing Date, except to the extent such refund or credit arises as the result of a carryback of a loss or other tax benefit from a Tax period (or portion thereof) beginning after the Closing Date. Buyer shall pay, or cause to be paid, to Sellers any amount to which Seller is entitled pursuant to the prior sentence, less reasonable out-of-pocket costs incurred in obtaining such refund or credit, within five (5) Business Days of the receipt or recognition of the applicable refund or credit by Buyer or its Affiliates. To the extent requested by Sellers, Buyer will reasonably cooperate with Sellers in obtaining such refund or credit, including through the filing of amended Tax Returns for periods ending before or on the Closing Date or refund claims.

(f)    The Parties agree to furnish to each other, upon request, as promptly as practicable, such information and assistance relating to the Companies as is reasonably necessary for the filing of all Tax Returns, and making of any election related to Taxes, the preparation for any audit by any Tax Authority and the prosecution or defense of any action, suit or proceeding related to Taxes involving the Company, and

each shall execute and deliver such documents as are reasonably necessary to carry out the intent of this Section 7.5. The Party requesting such information and assistance shall reimburse the other Party for all reasonable expenses incurred in connection with providing such information and assistance.

Section 8.4    Termination of Agreement. This Agreement may be terminated prior to the Closing as follows:

(a)At the election of Sellers or Buyer on or after March 30, 2018 (the “Termination Date”), if the Closing shall not have occurred by the close of business on such date; provided, however, that the terminating Party is not in material default of any of its obligations hereunder;

Section 8.6    Effect of Termination.

(a)In the event that this Agreement is terminated in accordance with Section 8.4, then each of the Parties shall be relieved of their respective duties and obligations arising under this Agreement after the date of such termination and such termination shall be without liability to Buyer or Sellers; provided, that (i) no such termination shall relieve any Party from liability for any breach of this Agreement and (ii)

the obligations of the Parties set forth in Article X hereof shall survive any such termination and shall be enforceable hereunder.

(b)Nothing in this Section 8.6 shall relieve Buyer or Sellers of any liability for a breach of this Agreement prior to the date of termination and the non‑breaching Party’s right to pursue all legal and equitable remedies will survive such termination. The damages recoverable by the non‑breaching Party shall include all attorneys’ fees reasonably incurred by such Party in connection with the transactions contemplated hereby. Nothing in this Section 8.6 shall be deemed to limit the rights of the Parties contained in Section 10.10.

Section 9.1    Assumption and Indemnification by Buyer. From and after the Closing, Buyer shall assume and hereby agrees to fulfill, perform, pay and discharge (or cause to be fulfilled, performed, paid or discharged) all duties, obligations and liabilities (including with respect to Taxes as set forth in Article IX) of the Companies or arising under the Companies’ Governing Documents or relating to the subject matter thereof, or otherwise under any theory of Law, arising on or after the Closing Date (the “Assumed Obligations”).

Section 9.2    Survival Periods. All representations and warranties other than Section 3.7 contained in this Agreement or in any Schedule to this Agreement, or in any certificate, document or other instrument delivered in connection with this Agreement, and the right to commence any claim with respect thereto, shall terminate and cease to be of further force and effect as of the date which is eighteen (18) months following the Closing Date. The representations and warranties set forth in Section 3.7 shall survive indefinitely. Those covenants that contemplate or may involve actions to be taken or obligations in effect after the Closing shall survive in accordance with their terms (the “Surviving Covenants”). Notwithstanding the foregoing, any covenant, agreement, representation, warranty or other matter in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to this Section 9.2, if notice of the inaccuracy or breach thereof or other matter giving rise to such right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time.

Section 9.3    Indemnification by the Sellers. Subject to the terms and conditions of this Article IX, including the limitations set forth in Section 9.2 and Section 9.6, from and after the Closing Date, each of the Sellers shall jointly and severally indemnify and hold harmless Buyer and its Affiliates and each of their respective directors, officers, employees, and agents (collectively, the “Buyer Indemnified Parties”) from and against any and all Losses resulting from or arising out of:

(a)    any breach or inaccuracy of any representation or warranty of the Sellers contained in Article III;

(b)    any breach of any covenant contained in this Agreement to be performed by the Sellers;

(d)    the Sellers Retained Liabilities.

(a)    any breach or inaccuracy of any representation or warranty of Buyer contained in Article IV;

(b)    any breach of any covenant contained in this Agreement to be performed by Buyer; or

(c)    the Assumed Obligations.

Section 9.5    Indemnification Procedures. The obligations of the Sellers to indemnify the Buyer Indemnified Parties under Section 9.3 with respect to Losses incurred by Buyer, and the obligations of Buyer to indemnify the Sellers Indemnified Parties under Section 9.4 with respect to Losses incurred by the Sellers, in either case arising out of or resulting from the assertion of liability or any Legal Proceeding by third parties who are not Affiliated with a Party to this Agreement (each, as the case may be, a “Third-Party Claim”), will be subject to the terms and conditions of the following clauses (a) through (e):

(a)    A party claiming indemnification under this Agreement (an “Indemnified Party”) shall promptly after receiving written notice of any Third-Party Claim, but in no event later than twenty (20) days thereafter, transmit to the party or parties from whom indemnification is sought under this Agreement (the “Indemnifying Party”) a written notice of the Third-Party Claim (a “Claim Notice”) describing in reasonable detail the nature of the Third-Party Claim, attaching a copy of all papers served to such Indemnified Party with respect to such Third-Party Claim (if any), setting forth a reasonable estimate of the amount of Losses attributable to the Third-Party Claim to the extent feasible (which estimate shall not be conclusive of the final amount of Losses arising from or relating to such Third-Party Claim), and describing in reasonable detail the basis of the Indemnified Party’s request for indemnification under this Agreement. Any failure or delay to provide such Claim Notice within such specified time period shall not release or relieve the Indemnifying Party from its liability under this Article IX or affect the right of an Indemnified Party to indemnification hereunder, except to the extent (and only to the extent) the Indemnifying Party is prejudiced by such failure or delay.

(b)    Within twenty (20) days after receipt of any Claim Notice (the “Election Period”), the Indemnifying Party shall notify the Indemnified Party (i) whether the Indemnifying Party disputes its potential liability to the Indemnified Party under this Article IX with respect to such Third-Party Claim and (ii) whether the Indemnifying Party desires, at its sole cost and expense and in accordance with Section 9.5(c), to defend the Indemnified Party against such Third-Party Claim. If the Indemnifying Party does not notify the Indemnified Party within such Election Period that the Indemnifying Party disputes its potential liability with respect to such Third-Party Claim, any liability with respect to such Third-Party Claim shall be deemed a disputed liability of the Indemnifying Party hereunder.

(c)    Subject to Section 9.5(d), if the Indemnifying Party notifies the Indemnified Party within the Election Period that the Indemnifying Party elects to assume the defense of such Third-Party Claim, then the Indemnifying Party shall have the right to defend, at its sole cost and expense, such Third-Party Claim by all appropriate proceedings with counsel of its choosing (but reasonably satisfactory to the Indemnified Party); provided, that that the Indemnified Party may participate in any such proceeding with counsel of its choice and at its expense. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that the Indemnifying Party shall obtain the prior written consent of the Indemnified Party before entering into any compromise or settlement of such Third-Party Claim, which consent shall not be unreasonably withheld; provided further, that no such consent shall be required for any such compromise or settlement that: (A) is exclusively monetary and will be paid in full by the Indemnifying Party (rather than the Indemnified Party); (B) does not contain an admission of liability on the part of any Indemnified Party; and (C) unconditionally and fully releases the Indemnified Party with respect to such Third Party Claim. If reasonably requested by the Indemnifying Party, the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in contesting any Third-Party Claim that the Indemnifying Party elects to contest in good faith pursuant to this Section 9.5(c), including by providing the Indemnifying Party with reasonable access during normal business hours of the Indemnified Party to books, records and personnel of the Indemnified Party (but only to the extent relevant to such Third-Party Claim), and in making any related counterclaim against the Person asserting the Third-Party Claim or any cross-complaint against any Person. Except as otherwise provided herein, the Indemnified Party may participate in, but not control, any defense or settlement of any Third-Party Claim controlled by the Indemnifying Party pursuant to this Section 9.5(c), and to retain counsel of the Indemnified Party’s own choice in connection with such participation, and the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(d)    If within the Election Period the Indemnifying Party has delivered a written notice to the Indemnified Party to the effect that the Indemnifying Party disputes its potential liability to the Indemnified Party under this Article IX with respect to such Third-Party Claim, or by the Indemnifying Party’s failure to respond, the Indemnifying Party is deemed to dispute its potential liability, and if such dispute is finally and conclusively resolved by a court of competent jurisdiction in favor of the Indemnified Party, the Indemnifying Party shall be required to bear the costs and expenses of the Indemnified Party’s defense of such Third-Party Claim pursuant to this Section 9.5(d).

(e)    The non-controlling party in the defense of a Third-Party Claim shall have the right to consult with the party controlling such defense, and the controlling party shall facilitate such consultation, with respect to the conduct, status, developments and results of the defense of such Third-Party Claim and the controlling party’s strategy for addressing the matters that are the basis of such Third-Party Claim.

(f)    In the event any Indemnified Party should have a claim for indemnification hereunder against any Indemnifying Party that does not involve a Third-Party Claim (an “Indemnity Claim”), the Indemnified Party shall promptly transmit to the Indemnifying Party a written notice of such Indemnity Claim (an “Indemnity Notice”) describing in reasonable detail the nature of the Indemnity Claim, and setting forth a reasonable estimate of the amount of Losses attributable to such Indemnity Claim to the extent feasible (which estimate shall not be conclusive of the final amount of Losses arising from or relating to such Indemnity Claim) and the basis of the Indemnified Party’s request for indemnification under this Agreement. Any failure or delay to provide such Indemnity Notice shall not release or relieve the Indemnifying Party from its liability under this Article IX or affect the right of an Indemnified Party to indemnification hereunder, except to the extent (and only to the extent) the Indemnifying Party is actually prejudiced by such failure or delay.

(g)    Within twenty (20) days after receipt of any Indemnity Notice, the Indemnifying Party shall notify the Indemnified Party whether the Indemnifying Party disputes its potential liability to the Indemnified Party under this Article IX with respect to such Indemnity Claim. If the Indemnifying Party does not notify the Indemnified Party within twenty (20) days from its receipt of the Indemnity Notice that the Indemnifying Party disputes such Indemnity Claim, any liability with respect to such Indemnity Claim shall be deemed a disputed liability of the Indemnifying Party hereunder.

(h)    With respect to Sellers’ obligation to indemnify the Sellers Indemnified Parties pursuant to Section 9.3(c), Sellers shall use commercially reasonable efforts to continue using counsel currently handling such Legal Proceedings and Buyer hereby consents to Sellers’ use of such counsel.

Section 9.6    Limitations.

(a)    No indemnity shall be payable to the Buyer Indemnified Parties under Section 9.3(a) with respect to any claim resulting from any breach or inaccuracy of any representation or warranty, unless and until the aggregate of all Losses related thereto due from the Sellers exceeds $500,000 (the “Deductible”), in which event all Losses so due in excess of the Deductible shall be paid in the aggregate by the Sellers; provided, that the aggregate amount payable by the Sellers for all Losses arising under Section 9.3(a) with respect to any claim resulting from any breach or inaccuracy of any representation or warranty shall not exceed $5,000,000 (the “Cap”).

(b)    No indemnity shall be payable to the Sellers Indemnified Parties under Section 9.4(a) with respect to any claim resulting from any breach or inaccuracy of any representation or warranty, unless and until the aggregate of all Losses due from Buyer exceeds the Deductible, in which event all Losses so due in excess of the Deductible shall be paid in full by Buyer; provided, that the aggregate amount payable by Buyer for all Losses arising under Section 9.4(a) of this Agreement shall not exceed the Cap.

(c)    Notwithstanding anything to the contrary contained in this Agreement, neither the Deductible nor the Cap shall apply to Losses arising out of (i) Taxes for which either Party is liable pursuant to this Article IX, (ii) any Indebtedness of the Companies existing prior to the Closing, (iii) the matters described in Section 9.3(b), Section 9.3(c) or Section 9.3(d), (iv) the matters described in Section 9.4(b) or Section 9.4(c), (v) claims for any breach of any representation or warranty in Section 3.7, or (vi) actual fraud or intentional misrepresentation.

Section 9.7    Mitigation. Each Indemnified Party shall, and is obligated to, take all reasonable steps to mitigate all indemnifiable Losses upon and after becoming aware of any event which could reasonably be expected to give rise to any Losses hereunder.

Section 9.8    No Duplication. Any Losses giving rise to liability for indemnification hereunder shall be determined without duplication of recovery by reason of the same set of facts giving rise to such Losses constituting a breach of more than one representation, warranty, covenant or agreement. For purposes of this Agreement, Losses shall be calculated after giving effect to any amounts actually recovered from third parties, including amounts actually recovered under insurance policies with respect to such Losses, net of any costs to recover such amounts, including any deductibles, co-payments or other reasonable and documented costs and expenses (including attorneys’ fees and other costs of collection) resulting from the related claims under applicable insurance policies. Any Indemnified Party having a claim under these indemnification provisions shall make a good-faith effort to recover all losses, costs, damages and expenses

from insurers of such Indemnified Party under applicable insurance policies so as to reduce the amount of any Losses hereunder; provided, that actual recovery of any insurance shall not be a condition to the Indemnifying Party’s obligation to make indemnification payments to the Indemnified Party in accordance with the terms of this Agreement. If the Indemnifying Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for a Loss, after an indemnification payment by the Indemnifying Party has been made for such Loss, then the Indemnified Party shall promptly reimburse the Indemnifying Party for such indemnification payment up to the amount so received or realized by the Indemnified Party, net of any costs to recover such amounts, including any deductibles, co-payments or other reasonable and documented costs and expenses (including attorneys’ fees and other costs of collection) resulting from the related claims under applicable insurance policies.

Section 9.9    Limitation on Damages. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL ANY PARTY BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL, SPECULATIVE OR INDIRECT DAMAGES, ANY LOSS OF FUTURE REVENUE, INCOME OR LOST PROFITS, DIMINUTION IN VALUE, DAMAGE TO REPUTATION OR LOSS OF GOODWILL, WHETHER BASED IN CONTRACT, TORT, STRICT LIABILITY OR OTHERWISE AND NO “MULTIPLE OF PROFITS” OR “MULTIPLE OF CASH FLOW” OR SIMILAR METHODOLOGY SHALL BE USED IN CALCULATING THE AMOUNT OF ANY DAMAGES; PROVIDED, HOWEVER, THAT THIS SECTION 9.9 SHALL NOT LIMIT A PARTY’S RIGHT TO RECOVER ANY SUCH DAMAGES TO THE EXTENT THAT SUCH PARTY IS REQUIRED TO PAY SUCH DAMAGES TO A THIRD PARTY IN CONNECTION WITH A MATTER FOR WHICH SUCH PARTY IS OTHERWISE ENTITLED TO INDEMNIFICATION PURSUANT TO THIS ARTICLE IX.

Section 9.10    Exclusive Remedies.

Section 10.6    Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns; provided, however, neither Party shall have the right to assign this Agreement without the prior written consent of the other Parties. Any attempted assignment in violation of this Section 10.6 shall be void.

Section 10.7    Third-Party Beneficiaries. This Agreement is not intended to confer upon any Person not a Party hereto any rights or remedies hereunder except as expressly provided in Article IX, and no Person other than the Parties hereto is entitled to rely on any representation, covenant, or agreement contained herein.

Section 10.8    Amendments and Waivers. This Agreement may not be modified or amended except by an instrument or instruments in writing signed by each of the Parties. Any Party may, only by an

instrument in writing, waive compliance by the other Parties with any term or provision of this Agreement on the part of such other Parties to be performed or complied with. The waiver by any Party of a breach of any term or provision of this Agreement shall not be construed as a waiver of any subsequent breach.

Section 10.9    Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to affect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the fullest extent possible.

Section 10.10    Specific Performance; Time of Essence. Each Party acknowledges and agrees that if any of the provisions of this Agreement were not performed in accordance with their specific terms, it would cause irreparable damage to the other Parties hereto for which no adequate remedy at Law would exist. Therefore, the obligations of each Party under this Agreement shall be enforceable by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith, including to prevent breaches of this Agreement, and this right shall include the right of the Parties to cause the transactions contemplated hereby to be consummated in each case without posting a bond or undertaking. Each Party hereto waives any defenses in any action for specific performance, including that a remedy at Law would be adequate. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to any other remedies which any party may have under this Agreement or otherwise. The Parties agreement that time is of the essence in this Agreement.

Section 10.11    Waiver of Conflicts Regarding Representation. Recognizing that Haynes and Boone LLP (“HB”) has acted as legal counsel to Sellers, Companies and certain of their Affiliates prior to the Closing, and that HB may act as legal counsel to Sellers and certain of its Affiliates after the Closing, the Buyer, on behalf of itself and the Companies, hereby expressly waive any current or future conflicts that may arise in connection with HB representing Sellers or any of its Affiliates after the Closing with respect to the transactions contemplated by this Agreement.

Section 10.12    Attorney-Client Privilege. Each of the Parties also agrees that Sellers have a reasonable expectation of privacy and privilege with respect to their communications (in all forms) with HB prior to the Closing to the extent such communications concern this Agreement, the Maritech APA, and/or the MIPSA, and the agreements and documents delivered hereunder and thereunder and the transactions contemplated hereby and thereby. Each of the Parties likewise agrees that third parties and their counsel with a common legal interest with Sellers also have a reasonable expectation of privacy and privilege with respect to their communications prior to the Closing (“Common Interest Parties”). At and after the Closing, the attorney-client privilege of the Companies with HB with respect to such matters, and the Common Interest Parties with their counsel shall be deemed to be the right of Sellers or the Common Interest Party respectively, and not that of the Companies, and may be waived only by Sellers or Common Interest Party as to their

respective communications. Absent the consent of Sellers, the Common Interest Party, or except as required to comply with any Law or other regulatory requirement applicable to Buyer or its Affiliates, neither Buyer nor the Companies shall have a right to access attorney-client privileged material of the Companies with respect to this Agreement, the Maritech APA and MIPSA and the other documents contemplated herein and the transactions contemplated hereby and thereby following the Closing. Notwithstanding the foregoing, (a) nothing herein shall be construed as a waiver by the Companies of the attorney-client privilege or the obligations of confidentiality owed by HB to the Companies with respect to matters not regarding this Agreement and the other agreements and documents delivered hereunder and the transactions contemplated hereby and thereby, (b) in the event that a dispute arises between Buyer or the Companies and a third Person other than a Party to this Agreement after the Closing, (i) the Companies may assert the attorney-client privilege to prevent disclosure of confidential communications by HB to such third Person and (ii) to the extent any such privilege or client confidence is required to be waived or otherwise required to be released by any Governmental Entity, under law or pursuant to any orders, decrees, writs, injunctions, judgments, stipulations, determinations or awards entered by or with any Governmental Entity, none of the Companies, Buyer or their Affiliates shall be in breach or violation of any provision of this Agreement or any document or agreement delivered hereunder for providing information, documents, communications or client confidences to any Governmental Entity in response to, and subject to the requirement limitation in, the foregoing.

IN WITNESS WHEREOF, each of the undersigned has caused this Agreement to be duly signed as of the date first above written.
