In no event shall Seller under any circumstances whatsoever be liable for Damages under this Section 5 (other than with respect to a breach of Section 3.10 relating to the payment of Income Taxes only) in excess of $825,000; provided, however, that, with respect to a breach of Section 3.10 relating to the payment of Income Taxes only, Seller shall not be liable for Damages under this Section 5 in excess of $1,500,000.

	(c) The remedy provided in this Section 5 shall be deemed to be sole and exclusive of any other rights that any of the Indemnified Persons may have with respect to any of the Contemplated Transactions.

	(e) The Indemnified Persons shall take all commercially reasonable steps to mitigate any Damage upon becoming aware of any event which would reasonably be expected to, or does, give rise thereto, including incurring costs only to the minimum extent reasonably necessary to remedy the breach which gives rise to the Damage. Any liability of the Indemnitors to indemnify the Indemnified Persons for Damages shall be net of insurance proceeds and Tax benefits received by the Indemnified Persons related to the matter in question. The Indemnified Persons shall use commercially reasonable efforts to pursue all insurance claims to which they may be entitled in connection with any Damages to incur, and the Indemnified Persons shall cooperate with each other in pursuing insurance claims with respect to any Damages. If the Indemnified Persons receive any insurance payment or Tax benefits in connection with any claim for damages for which they have already received an indemnification payment from the Indemnitor, they shall pay to the Indemnitor within ten days of receiving such insurance payment or Tax benefit an amount equal to the excess of (i) the amount previously received by the Indemnified Persons under this Section 5 with respect to such claim, plus the amount of the insurance payments or Tax benefits received, over (ii) the amount of Damage with respect to such claim which the Indemnified Persons were entitled to receive under this Section 5.

Such Indemnified Person shall permit the Indemnitor to use the name of such Indemnitee in any transaction or in any proceeding or other matter involving any of such rights or remedies; and the Indemnified Persons shall take such actions as the Indemnitor may reasonably request for the purpose of enabling the Indemnitor to perfect or exercise the Indemnitor’s right of subrogation hereunder.

	5.6	PROCEDURE FOR INDEMNIFICATION--THIRD PARTY CLAIMS

	(a) Promptly after receipt by an Indemnified Person of notice of the commencement of any Proceeding against it, such Indemnified Person will, if a claim is to be made against an Indemnitor, give notice to such Indemnitor of the commencement of such claim, but the failure to notify such Indemnitor will not relieve such Indemnitor of any liability that it may have to any Indemnified Person, except to the extent that such Indemnitor demonstrates that the defense of such action is materially prejudiced by such Indemnitor’s failure to give such notice.

	Page 26 of 34	Equity Purchase Agreement
		Petroleum Mud Logging, LLC

	(b) If any Proceeding referred to in Section 5.6(a) is brought against an Indemnified Person and it gives notice to an Indemnitor of the commencement of such Proceeding, such Indemnitor will be entitled to participate in such Proceeding and, to the extent that it wishes (unless (i) such Indemnitor is also a party to such Proceeding and the Indemnified Person determines in good faith that joint representation would be inappropriate or (ii) such Indemnitor fails to provide reasonable assurance to the Indemnified Person of its financial capacity to defend such Proceeding and provide indemnification with respect to such Proceeding), to assume the defense of such Proceeding with counsel satisfactory to the Indemnified Person and, after notice from such Indemnitor to the Indemnified Person of its election to assume the defense of such Proceeding, such Indemnitor will not, as long as it diligently conducts such defense, be liable to the Indemnified Person under this Section 5 for any fees of other counsel or any other expenses with respect to the defense of such Proceeding, in each case subsequently incurred by the Indemnified Person in connection with the defense of such Proceeding, other than reasonable costs of investigation. If such Indemnitor assumes the defense of a Proceeding, (i) it will be conclusively established for purposes of this Agreement that the claims made in that Proceeding are within the scope of and subject to indemnification; (ii) no compromise or settlement of such claims may be effected by such Indemnitor without the Indemnified Person’s consent unless (A) there is no finding or admission of any violation of Laws or any violation of the rights of any Person and no effect on any other claims that may be made against the Indemnified Person, and (B) the sole relief provided is monetary damages that are paid in full by such Indemnitor; and (iii) the Indemnified Person will have no liability with respect to any compromise or settlement of such claims effected without its consent. If notice is given to the respective Indemnitor of the commencement of any Proceeding and such Indemnitor does not, within ten days after the Indemnified Person’s notice is given, give notice to the Indemnified Person of its election to assume the defense of such Proceeding, such Indemnitor will be bound by any determination made in such Proceeding or any compromise or settlement effected by the Indemnified Person.

	(c) Notwithstanding the foregoing, if an Indemnified Person determines in good faith that there is a reasonable probability that a Proceeding may adversely affect it or its affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the Indemnified Person may, by notice to the respective Indemnitor, assume the exclusive right to defend, compromise or settle such Proceeding, but such Indemnitor will not be bound by any determination of a Proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld).

	5.7	PROCEDURE FOR INDEMNIFICATION--OTHER CLAIMS

	A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to an Indemnitor.
