In the event Buyer or any of the Companies incurs any out-of-pocket costs in complying with this Section 7.14, then Buyer or the Company may either (i) provide written notice of such costs (including reasonable supporting documentation thereof) to Seller and within ten (10) Business Days of receipt, Seller shall reimburse Buyer or the Companies, as applicable, for all such documented costs or (ii) to the extent any Retained Claims Amounts are received by the Companies (or Buyer or its Affiliates on behalf of the Companies), reduce the Retained Claims Amounts paid to Seller pursuant to this Section 7.14 by an amount equal to all such documented costs. NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, SELLER SHALL RELEASE, DEFEND, INDEMNIFY AND HOLD HARMLESS THE COMPANIES, BUYER AND BUYER’S AFFILIATES FROM ANY AND ALL COSTS, EXPENSES OR OTHER LOSSES RELATED TO SUCH RETAINED CLAIMS, INCLUDING, FOR THE AVOIDANCE OF DOUBT, (X) ANY TAXES ASSOCIATED WITH THE RETAINED CLAIMS AMOUNTS OR RECEIPT THEREOF AND (Y) ANY COSTS, EXPENSES, OR OTHER LOSSES OR LIABILITIES WITH RESPECT TO ANY COUNTERCLAIM ASSERTED AGAINST ANY COMPANY, BUYER OR BUYER’S AFFILIATES IN CONNECTION WITH SUCH RETAINED CLAIMS.

Buyer and Seller shall endeavor to agree on the Final Settlement Statement within thirty (30) days after Buyer’s receipt of Seller’s proposed changes thereto. If Buyer and Seller are unable to agree on any amounts (the “Disputed Amounts”) on the Final Settlement Statement during such thirty (30) day period, then Buyer and Seller shall submit all unresolved Claims to Hilliard & Associates, P.C. (or, if such firm is unable or unwilling to act, such other nationally recognized independent public accounting firm as shall be agreed upon by Buyer and Seller in writing) (the “Referral Firm”) to review such Disputed Amounts in Buyer’s Final Settlement Statement and Seller’s Dispute Notice and the records relating to the Disputed Amounts and determine the final adjustments with respect thereto.

The Referral Firm shall deliver its final calculation of the Disputed Amounts in writing to Buyer and Seller as soon as is practicable, and the Party owing any amount for additional adjustments as a result thereof shall pay such amount no later than the tenth (10th) Business Day following the paying Party’s receipt from the Referral Firm of the final adjustments. If the Parties reach agreement on the Final Settlement Statement, payment by the Party obligated to do so shall be due on the later of (a) the thirtieth (30^th) day after the date on which Seller receives the Final Settlement Statement from Buyer, or (b) five (5) Business Days after such agreement is reached.

Subject to Section 7.11, Buyer agrees to maintain all original Records in accordance with its records retention policy, as same may be amended from time to time, or, if any of such Records pertain to a Claim pending at such time as the Records would otherwise be destroyed, until such Claim is finally resolved and the time for all appeals has been exhausted.

9.3. Further Cooperation. After the Closing Date, Buyer and Seller shall take such other actions as either Party may reasonably request, to consummate and give effect to the transactions hereunder and to accomplish the orderly transfer of the Company Interests to Buyer. If, after the Closing Date, either Party receives monies belonging to the other, such amounts shall be promptly disbursed to the Party entitled to receive them. If an invoice or other evidence of an obligation is received by a Party, which is either an obligation assumed by the other Party or partially an obligation of both Seller and Buyer, the Parties shall consult with each other, and an adjustment for such amount will be made on the Final Settlement Statement. In the event an invoice or other evidence of an obligation is received by a Party, which is either an obligation assumed by the other Party or partially an obligation of both Seller and Buyer following the final calculation of the Final Settlement Statement there shall be no further payments to the other Party.

(a) For purposes of this Article X, the term “Indemnifying Party”, when used in connection with particular Losses, shall mean the Party having an obligation to indemnify another Party or Person(s) with respect to such Losses pursuant to this Article X, and the term “Indemnified Party”, when used in connection with particular Losses, shall mean the Party or Person(s) having the right to be indemnified with respect to such Losses by another Party pursuant to this Article X.

(b) To make a Claim for indemnification under Section 6.1, Section 10.1 or Section 10.2, an Indemnified Party shall notify the Indemnifying Party of its Claim under this Section 10.6, including the specific details of and specific basis under this Agreement for its Claim (the “Claim Notice”) prior to the expiration of such representation, warranty, covenant or agreement pursuant to Section 10.7(a). In the event that the Claim for indemnification is based upon a Claim by a third party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 10.6 shall not relieve the Indemnifying Party of its obligations under Section 10.1 or Section 10.2 (as applicable) except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a Claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have thirty (30) calendar days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its liability to defend the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such thirty (30) day period, at the expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party admits its obligation to indemnify a Third Party Claim, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Third Party Claim; provided that, where the Third Party Claim consists of a civil, criminal or regulatory proceeding, action, indictment or investigation against the Indemnified Party by any Governmental Authority, the Indemnified Party shall at its option have the right to control the defense and proceedings. Except as provided in the preceding sentence, the Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified

- 28 -

Party agrees to cooperate in contesting any Third Party Claim that the Indemnifying Party elects to contest (provided, however, that the Indemnified Party shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Party may participate in, but not control, at its own expense, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 10.6(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not result in a final resolution of the Indemnified Party’s liability in respect of such Third Party Claim (including in the case of a settlement an unconditional written release of the Indemnified Party from all liability for Losses in respect of such Third Party Claim) or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Party does not admit its obligation to indemnify and bear all expenses associated with a Third Party Claim or admits its obligation to indemnify and bear all expenses associated with a Third Party Claim but fails to diligently prosecute or settle the Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its obligation to indemnify and bear all expenses associated with a Third Party Claim and assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its obligation to indemnify and bear all expenses associated with a Third Party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) Business Days following receipt of such notice to (i) admit in writing its obligation to indemnify and bear all expenses associated with a Third Party Claim and (ii) if such obligation is so admitted, reject, in its reasonable judgment, the proposed settlement.

(f) In the case of a Claim for indemnification not based upon a Third Party Claim, the Indemnifying Party shall have thirty (30) calendar days from its receipt of the Claim Notice to (i) cure the Losses complained of, (ii) admit its obligation to indemnify for and bear all expenses associated with such Losses or (iii) dispute the Claim for such Losses. If the Indemnifying Party does not notify the Indemnified Party within such thirty (30) day period that it has cured the Losses or that it disputes the Claim for such Losses, the amount of such Losses shall conclusively be deemed a liability of the Indemnifying Party hereunder.

10.7. Survival.

(a) The representations and warranties of Seller contained in Article III and Article IV (other than the representations and warranties set forth in Section 4.11) shall, in each case, terminate on December 31, 2020.

- 29 -

(b) The indemnities in Section 10.1(a), Section 10.1(b), Section 10.2(a), and Section 10.2(b) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification as set forth in Section 10.7(a). The indemnities in Section 10.1(c), Section 10.1(d) and Section 10.1(e) shall survive until December 31, 2020. The indemnities in Section 10.2(c) and Section 10.2(d) shall survive until December 31, 2020. Notwithstanding the foregoing, there shall be no termination of any bona fide Claim asserted pursuant the indemnities in Section 10.1 or Section 10.2 prior to the date of termination for such indemnity.

10.8. Non-Compensatory Damages. None of the Buyer Indemnified Parties or Seller Indemnified Parties shall be entitled to recover from Seller or Buyer, as applicable, or their respective Affiliates, any indirect, incidental, special, consequential, punitive or exemplary damages or damages for lost profits of any kind arising under or in connection with this Agreement, or the transactions contemplated by hereby, except to the extent any such Party suffers such damages (including costs of defense and reasonable attorney’s fees incurred in connection with defending of such damages) to a third party, which damages (including costs of defense and reasonable attorney’s fees incurred in connection with defending against such damages) shall not be excluded by this provision as to recovery hereunder. SUBJECT TO THE PRECEDING SENTENCE, BUYER, ON BEHALF OF EACH OF THE BUYER INDEMNIFIED PARTIES, AND SELLER, ON BEHALF OF EACH OF THE SELLER INDEMNIFIED PARTIES, EACH WAIVE ANY RIGHT TO RECOVER PUNITIVE, SPECIAL, EXEMPLARY AND CONSEQUENTIAL DAMAGES, INCLUDING DAMAGES FOR LOST PROFITS OF ANY KIND, ARISING IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. THIS SECTION 10.8 SHALL NOT RESTRICT ANY PARTY’S RIGHT TO OBTAIN SPECIFIC PERFORMANCE OR OTHER EQUITABLE REMEDIES (OTHER THAN RESCISSION) PURSUANT TO SECTION 11.12.

10.9. Waiver of Right of Rescission. Seller and Buyer acknowledge that, subject to any express rights the Parties may have hereunder to seek and obtain specific performance hereunder or other equitable remedies, following Closing, the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other Claim arising in connection with or with respect to the transactions contemplated by this Agreement. As such, Buyer and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.

10.10. Mutual Release. Effective upon the Closing, (a) Seller shall release and discharge each of the Companies from any and all obligations and Losses to Seller as an equityholder (whether directly or indirectly) of any Company of any kind or nature whatsoever, as to facts, conditions, transactions, events or circumstances prior to the Closing, and Seller shall not seek to recover any amounts in connection therewith from any Company and (b) each Company shall release and discharge each Seller Party and its Affiliates and their respective equityholders, officers, directors, managers, employees, agents, partners, members, counsel, accountants, financial advisors, engineers, consultants, other advisors, successors and assigns, from any and all obligations and Losses of any kind or nature whatsoever, as to facts, conditions, transactions, events or circumstances prior to the Closing, and Buyer shall ensure that no Company shall seek to recover any amounts in connection therewith from Seller or of its Affiliates and their respective equityholders, officers, directors, managers, employees, agents, partners, members, counsel, accountants, financial advisors, engineers, consultants, other advisors, successors or assigns; provided, however, that this Section 10.10 shall not affect the rights of Seller, Buyer or either of the Companies under this Agreement.
