INDEMNIFICATION AND REMEDIES

8.1 Survival; Right to Indemnification Not Affected by Knowledge. Any and all representations, warranties, agreements, covenants, and obligations in this Agreement, the Related Agreements, the Seller Certificate, the Certificate of Officer, and the Buyer Certificate shall survive the Closing, except for any representations, warranties, agreements, covenants, obligations, and/or other provisions in this Agreement that by their terms apply or are to be performed in whole or in part prior to or after the Closing Date (the “Date Specific Provisions”) which shall be governed by the terms of survival set forth in the Date Specific Provisions with respect only to such Date Specific Provisions. Except as expressly set forth herein, the right to indemnification, reimbursement for, or payment of Buyer Damages or Seller Damages, as applicable, or other remedy based on any such representation, warranty, agreement, covenant, or obligation shall not be affected by any investigation conducted with respect to, or any Knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant, or obligation. Except as expressly set forth herein, the waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any agreement, covenant, or obligation, shall not affect the right to indemnification, reimbursement for, or payment of damages, or any other remedy based on such representation, warranty, agreement, covenant, and obligation.

8.2 Indemnification and Payment of Buyer Damages. Subject to the provisions and limitations of this Article VIII, the Seller shall indemnify, hold harmless, and promptly reimburse the Buyer and any Representative and Affiliate of the Buyer (each, a “Buyer Indemnified Person,” and, collectively, the “Buyer Indemnified Persons”) for, and shall pay to the Buyer Indemnified Persons the amount of, any loss, liability, claim, damage (including, without limitation, punitive, incidental, consequential, and special damages, except to the extent provided in Section 8.6 of this Agreement), expense (including, without limitation, reasonable costs of investigation and defense and reasonable attorneys’ fees) or diminution of value, whether or not involving any third-party claim, actually suffered, incurred, or realized by such Buyer Indemnified Person (collectively, “Buyer Damages”), arising, directly or indirectly, from or in connection with:

(a) any Breach of any representation or warranty made by the Seller in this Agreement, the Related Agreements, the Seller Certificate, or any other certificate or document delivered by the Seller pursuant to this Agreement;

(b) any Breach of any representation or warranty made by the Seller in this Agreement as if such representation or warranty were made on and as of the Closing Date (except for changes contemplated by this Agreement and except to the extent any such representation or warranty speaks of an earlier and/or later date and/or time, in which case such representation or warranty shall have been true, accurate, and complete as of such earlier and/or later date and/or time), other than any such Breach that is expressly identified in the Seller Certificate as having caused the conditions specified in Sections 5.1.1 or 5.1.2, as applicable, not to be fulfilled and satisfied; or

(c) any Breach by the Seller of any agreement, covenant, or obligation of the Seller in this Agreement or the Related Agreements.

If the Seller is obligated to indemnify or reimburse the Buyer pursuant to this Article VIII with respect to any Buyer Damages, the Buyer shall have the right and option in the Buyer’s sole and absolute discretion to offset and apply the amount of such indemnification or reimbursement against the Purchase Price payable by the Buyer to the Seller.

8.3 Indemnification and Payment of Seller Damages. Subject to the provisions and limitations of this Article VIII, the Buyer shall indemnify, hold harmless, and promptly reimburse the Seller and any Representative and Affiliate of the Seller (each, a “Seller Indemnified Person,” and, collectively, the “Seller

Indemnified Persons”) for, and shall pay to the Seller Indemnified Persons the amount of, any loss, liability, claim, damage (including, without limitation, punitive, incidental, consequential, and special damages, except to the extent provided in Section 8.6 of this Agreement), expense (including, without limitation, reasonable costs of investigation and defense and reasonable attorneys’ fees) or diminution of value, whether or not involving any third-party claim, actually suffered, incurred, or realized by such Seller Indemnified Person (collectively, “Seller Damages”), arising, directly or indirectly, from or in connection with:

(a) any Breach of any representation or warranty made by the Buyer in this Agreement, the Related Agreements, the Buyer Certificate, or any other certificate or document delivered by the Buyer pursuant to this Agreement;

(b) any Breach of any representation or warranty made by the Buyer in this Agreement as if such representation or warranty were made on and as of the Closing Date (except for changes contemplated by this Agreement and except to the extent any such representation or warranty speaks of an earlier and/or later date and/or time, in which case such representation or warranty shall have been true, accurate, and complete as of such earlier and/or later date and/or time), other than any such Breach that is expressly identified in the Buyer Certificate as having caused the conditions specified in Sections 5.2.1 and 5.2.2 not to be fulfilled and satisfied; or

(c) any Breach by the Buyer of any agreement, covenant, or obligation of the Buyer in this Agreement or the Related Agreements.

Subject to Section 8.6 of this Agreement, the indemnification provided in this Section 8.3 shall be the sole and exclusive remedy available to the Seller and any other Seller Indemnified Person for any Breach of this Agreement, the Related Agreements, or the Buyer Certificate by the Buyer.

8.4 Procedure for Indemnification of Third Party Claims.

(a) Promptly after receipt by an indemnified party under Section 8.2 or 8.3 of notice of the commencement of any Proceeding against such indemnified party, such indemnified party shall, if a claim is to be made against an indemnifying party under such Section, give notice to the indemnifying party of the commencement of such claim; provided, however, that the failure to notify the indemnifying party shall not relieve the indemnifying party of any liability that such indemnifying party may have to any indemnified party, except to the extent that the indemnifying party demonstrates that the defense of such action is prejudiced by the indemnified party’s failure to give such notice.

(b) If any Proceeding referred to in Section 8.4(a) is brought against an indemnified party and such indemnified party gives notice to the indemnifying party of the commencement of such Proceeding, the indemnifying party shall be entitled to participate in such Proceeding and, to the extent that such indemnifying party wishes (unless (i) the indemnifying party is also a named party to such Proceeding and legal counsel to the indemnified party determines in good faith that joint representation would be inappropriate due to an ethical conflict or a material conflict of interest or (ii) the indemnifying party fails to provide reasonable assurance to the indemnified party of its financial capacity to competently defend such Proceeding and provide indemnification with respect to such Proceeding) to assume the defense of such Proceeding with counsel satisfactory to the indemnified party and, after notice from the indemnifying party to the indemnified party of its election to assume the defense of such Proceeding, the indemnifying party shall not, as long as such indemnifying party diligently conducts such defense, be liable to the indemnified party under this Article VIII for any fees of counsel or any other expenses with respect to the defense of such Proceeding, in each case subsequently incurred by the indemnified party in connection with the defense of such Proceeding,

other than reasonable costs of investigation. If the indemnifying party assumes the defense of a Proceeding, (i) no compromise or settlement of such claims may be effected by the indemnifying party without the consent of the indemnified party, which consent may not be unreasonably withheld, conditioned, or delayed, unless (A) there is no finding or admission of any violation of Legal Requirements and no effect on any other claims that may be made against the indemnified party and (B) the sole relief provided is monetary damages that are paid in full by the indemnifying party, and (ii) the indemnified party shall have no liability with respect to any compromise or settlement of such claims effected without the consent of such indemnified party. If notice is given to an indemnifying party of the commencement of any Proceeding and the indemnifying party does not, within fifteen (15) days after the such notice is given, give notice to the indemnified party of the election of the indemnifying party to assume the defense of such Proceeding (or the indemnifying party is also a party to such Proceeding and legal counsel to the indemnified party determines in good faith that joint representation would be inappropriate due to an ethical conflict or a material conflict of interest or the indemnifying party fails to provide reasonable assurance to the indemnified party of its financial capacity to competently defend such Proceeding and provide indemnification with respect to such Proceeding), the indemnified party shall be entitled to employ counsel to represent or defend the indemnified party in such Proceeding and the indemnifying party shall pay the reasonable fees and expenses of such counsel as incurred; provided, however, that the indemnifying party shall not be required to pay the fees and expenses of more than one (1) counsel for all indemnified parties in any jurisdiction in any single Proceeding. In any Proceeding with respect to which indemnification is sought hereunder, the indemnified party or the indemnifying party, whichever is not assuming the defense of such Proceeding, shall have the right to participate therein and to retain its own counsel at such party’s own expense. The indemnified party and the indemnifying party, as the case may be, shall at all times use Commercially Reasonable Efforts to keep the other party reasonably apprised of the status of the defense of any Proceeding, the defense of which such party is maintaining, and to cooperate in good faith with each other with respect to the defense of any such Proceeding.

(c) Notwithstanding the foregoing, if legal counsel to an indemnified party determines in good faith that there is a reasonable probability that a Proceeding may materially adversely affect such party or an Affiliate of such party other than as a result of monetary damages for which such party or such Affiliate of such party would be entitled to indemnification under this Agreement, the indemnified party may, by notice to the indemnifying party, assume the exclusive right to defend, compromise, or settle such Proceeding; provided, however, that the indemnifying party shall not be bound by any determination of a Proceeding so defended or any compromise or settlement effected without the consent of the indemnifying party (which may not be unreasonably withheld, conditioned, or delayed).

(d) Each of the parties hereto hereby consents to the non-exclusive jurisdiction of any court in Dallas County, Texas in which a Proceeding is brought against any indemnified party for purposes of any claim that any indemnified party may have under this Agreement with respect to such Proceeding or the matters alleged therein, and agree that process may be served on parties hereto with respect to such a claim anywhere in the world.

8.5 Procedure for Indemnification of Other Claims. A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the party from whom indemnification is sought.

8.6 Indemnification Limits. The indemnification obligations of the parties hereto pursuant to this Article VIII shall be limited to actual damages and shall not, except in the case of a willful Breach of this Agreement, include incidental, consequential, indirect, punitive, special, or exemplary damages, except that any incidental, consequential, indirect, punitive, special, or exemplary damages recovered by any third party against any party indemnified pursuant to this Article VIII shall be included in damages recoverable under

such indemnity. If any party is entitled to indemnification under more than one clause or subclause of this Article VIII with respect to any Buyer Damages or Seller Damages, then such party shall be entitled to only one indemnification or recovery of such Buyer Damages or Seller Damages to the extent such Buyer Damages or Seller Damages arise out of the same circumstances and events; it being understood that this sentence is solely to preclude a duplicate recovery by such party or recovery in excess of actual damages.

ARTICLE IX
