(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 thirty (30) 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 VII 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 VII 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 7.4(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 7.4(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 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 7.4(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 7.4(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 VII 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 7.4(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 VII 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 VII 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.

Section 7.5Limitations.

(a)No indemnity shall be payable to the Buyer Indemnified Parties under Section 7.2 with respect to any claim, unless and until the aggregate of all Losses related thereto due from TETRA Parent exceeds $500,000 (the “Deductible”), in which event all Losses so due in excess of the Deductible shall be paid in the aggregate by TETRA Parent; provided, that the aggregate amount payable by TETRA Parent for all Losses arising under Section 7.2 with respect to any claim shall not exceed $2,000,000 (the “Cap”).

(b)Notwithstanding anything to the contrary contained in this Agreement, neither the Deductible nor the Cap shall apply to Losses of the Buyer Indemnified Parties arising out of (i) claims for any breach of any representation or warranty in Section 3.2(a) or (ii) the matters described in Section 7.2(b) or Section 7.2(d).

(c)If prior to Closing, Buyer has knowledge of any inaccuracy or breach of any of the representations and warranties of Seller set forth herein and nonetheless proceeds with and consummates the Closing, then Buyer shall be deemed to have waived and forever renounced any right to assert a claim for indemnification under this Agreement.

Section 7.6Mitigation. 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 7.7No 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.
