ACCESS; DUE DILIGENCE

4.1 Access to Records. Through the Closing Date, Seller shall provide to Buyer and its representatives full access, during normal business hours (and, if reasonably requested, such other times as Buyer may deem necessary to complete its due diligence within the time period provided herein and for a period of one hundred twenty (120) days after the closing date) at Seller’s offices, to all books, records, documents, and information of every kind and character (including, without limitation, originals or photocopies, as available, of the Leases, the Real Property Interests, the Contracts, the Permits, the Records, and the Transferable Data) in Seller’s possession relating in any way to the Assets. Seller shall also cause their employees, counsel, accountants, and other consultants to cooperate with and assist Buyer in connection with such due diligence review. Unless prohibited from doing so by confidentiality or other contractual arrangements between Seller and third Persons, Buyer shall have the right to photocopy such books, records, documents, and information, or any portion thereof, at Buyer’s expense. If Buyer requests information not in the possession of Seller, Seller shall use reasonable efforts to obtain the requested information, at Buyer’s expense, from the applicable operators or other Persons.

4.2 Operation and Environmental Assessment. Through the Closing Date, Seller shall afford, or shall use reasonable efforts to cause relevant operators or other Persons to afford, to Buyer and its authorized representatives, at reasonable times and at the sole cost, risk, and expense of Buyer or its representatives, as applicable, reasonable access to and entry upon all of the Leases, ▇▇▇▇▇, and Real Property Interests for the purposes of Buyer’s on-site inspections and inventories of the Assets (including, without limitation, the witnessing of well tests, the examination of well logs and other geological and geophysical data, and the performance of soil and water tests and such other tests, inspections, examinations, investigations, and studies as Buyer deems necessary to permit

Buyer to prepare reserve engineering and other reports relating to, and assess the operational and environmental condition of, the Assets) and reasonable access to any employees or contract personnel that have been involved with the operation, maintenance, or development of the Assets.

4.3 Defects, Environmental Conditions and Related Adjustments. From time to time on or before the Closing Date and for one hundred twenty (120) days following the Closing Date, Buyer may give to Seller written notice of any claimed Defect or Environmental Condition discovered by Buyer. Each such notice shall set forth (i) a detailed description of the relevant Defect or Environmental Condition and, as applicable, the Asset affected thereby, (ii) the Defect Amount or Remediation Estimate applicable thereto as determined by Buyer, and (iii) the specific documentation or action that Buyer requests to cure or remedy such Defect or Environmental Condition. In addition, if Seller is aware or becomes aware, between the date of execution of this Agreement and the Closing Date, of any Environmental Condition affecting any Asset, Seller shall provide to Buyer written notice of such fact. Any Environmental Condition thus brought to Buyer’s attention by Seller shall be deemed to have been asserted by Buyer in a timely manner as provided in this Section 4.3(a). Defects and Environmental Conditions discovered by Buyer in its due diligence pertaining to the Assets but not asserted in a timely manner as provided in this Section 4.3(a) shall be deemed to have been waived by Buyer, and shall become Assumed Liabilities for purposes hereof.

(b) Seller shall have the first right and option, but not the obligation, to cure or remedy all such Defects or Environmental Conditions at Seller’s sole cost, risk, and expense (and in the case of an Environmental Condition, in accordance with applicable Environmental Laws) consistent with the current use of the Asset and in a manner reasonably acceptable to Buyer. If Seller elects to cure or remedy a Defect or Environmental Condition, Seller shall provide to Buyer written notice of such fact no later than three (3) Business Days after their receipt of Buyer’s notice. The failure of Seller to give such notice to Buyer within such three-Business Day period shall constitute an election by Seller not to cure or remedy the relevant Defect or Environmental Condition.

(c) If Seller elects to cure or remedy a Defect or Environmental Condition, Seller will commence such curative activities or remediation as soon as reasonably practicable after their receipt of Buyer’s notice and shall promptly and diligently continue such efforts until such Defect or Environmental Condition has been fully cured or remediated (in the case of an Environmental Condition, in accordance with applicable Environmental Laws), but in no event more than sixty (60) days after Buyer’s notice. If Seller does not complete such curative activities or remediation prior to the expiration of such sixty-day period, (i) Buyer may elect to offer Seller an extension of time within which to complete such curative or remedial actions; or (ii) in the absence of such an extension, Sections 4.3(d) and 4.3(e), or Section 4.3(f), as applicable, will govern.

(d) If Seller elects, or is deemed to have elected, not to cure a Defect asserted in a timely manner under Section 4.3(a), or if Seller is unable to cure a Defect in

a timely manner as provided in Section 4.3(c), then except as provided hereinafter, Buyer shall have the right to an adjustment to the Adjusted Cash Consideration, by the Defect Amount for such Defect, which adjustment shall be accomplished by access to the Holdback, as provided in Section 8.4 below, except that no downward adjustment of the Adjusted Cash Purchase Price on account of Defects shall occur unless the aggregate amount of all Defect Amounts exceeds $25,000 (the “Defect Amount Threshold”), but if the Defect Amount Threshold is met, the Defect Amount for all Defects shall reduce the Cash Purchase Price subject to the limits set forth in Section 8.4.

(e) If Buyer purchases at the Closing an Asset burdened by a preferential right to purchase or similar right that has not been exercised as of the Closing Date, regardless of whether the time period for the exercise of such right has expired, no reduction of the Adjusted Consideration paid at the Closing shall be made with respect thereto. If, for any reason, such preferential right to purchase or similar right is successfully exercised by the holder thereof after the Closing, Buyer shall be entitled to retain all proceeds paid for the affected Asset by the holder of the relevant preferential right to purchase or similar right, and Seller shall pay to Buyer, in cash, an amount equal to the excess (if any) of the Allocated Value of such Asset (adjusted as provided in Sections 2.3(c)(ii) and 2.3(d)(ii) and net of applicable Property-Related Taxes) over the proceeds received by Buyer from the holder of such preferential right to purchase.

(f) If Seller elects, or is deemed to have elected, not to remedy an Environmental Condition asserted in a timely manner under Section 4.3(a), or if Seller is unable to remedy an Environmental Condition in a timely manner as provided in Section 4.3(c), then except as provided hereinafter, Buyer shall receive a reduction in the Cash Purchase Price equal to the actual costs, including, without limitation, Liabilities to Governmental Authorities and other Persons (or in the absence of actual costs, the Remediation Estimate agreed to by Seller and Buyer or determined by arbitration as provided in Section 4.3(g)), to remedy the relevant Environmental Condition, in which case, such unremedied Environmental Condition shall become an Assumed Liability for purposes hereof.

(g) Seller and Buyer shall endeavor, in good faith, to agree on the existence of all claimed Defects or Environmental Conditions, the methods of curing or remedying such Defects or Environmental Conditions, and the Defect Amounts or Remediation Estimates applicable thereto. In the event of a dispute concerning any of such matters that is not resolved prior to the Closing, either Buyer or Seller may initiate arbitration of such dispute pursuant to the terms of Section 10.11. Following the issuance of the arbitrator’s decision, Seller and Buyer shall have the rights and options provided in Section 4.3(d) and Section 4.3(e), or Section 4.3(f), as applicable.

No later than

On or before fifteen (15) days after Buyer’s receipt of Seller’s proposed changes to the Final Settlement Statement, Buyer and Seller shall agree on the Final Settlement Statement and, as the case may be, shall pay to the other such sums as may be found to be due in the final accounting.

If Buyer and Seller are unable to agree on the Final Settlement Statement on or before fifteen (15) days after Buyer’s receipt of Seller’s proposed changes thereto, then Buyer and Seller shall submit all unresolved claims and amounts for arbitration in accordance with the terms of Section 10.11.

8.2 Further Cooperation. After the Closing Date, Buyer and Seller shall execute and deliver, or shall cause to be executed and delivered from time to time, such further instruments of conveyance and transfer, and shall take such other actions as either Party may reasonably request, to convey and deliver the Assets to Buyer, to perfect Buyer’s title thereto, and to accomplish the orderly transfer of the Assets to Buyer in the manner contemplated by this Agreement. If, after the Closing Date, either Seller or Buyer 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 Seller or Buyer, 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 either on the Final Settlement Statement, or, if the evidence of the obligation is not received until after the completion of the final accounting pursuant to Section 8.1, in cash as the Parties may agree. If Seller and Buyer are unable to agree on the disposition of such an obligation, Seller and Buyer shall submit the matter to binding arbitration in accordance with the terms of Section 10.11.

8.3 Undisbursed Revenues and Payment of Vendor Claims. No later than the Closing Date, Seller shall disburse to Buyer all monies (if any) relating to the Assets that Seller is obligated to pay or disburse to other Persons (including amounts held in suspense by Seller) and that, as of the Closing Date, have not been thus paid or disbursed. Buyer shall take and apply such funds in a manner consistent with prudent oil and gas business practices to satisfy the Claims of third Persons with respect to such monies.

Buyer shall give notice to Seller of any application by Buyer of any portion of the Holdback, and any dispute regarding such application shall be submitted for arbitration in accordance with the terms of Section 10.11.

Such survival does not obligate any Party to make any further representation or warranty after the Closing Date, or to cause any representation or warranty made hereunder to remain true and correct after the Closing Date.

9.2 Indemnity as Sole Remedy. Except to the extent otherwise provided in Section 6.4 and Section 8.4, the indemnity provided by each Party to the other under this Article IX shall constitute the sole and exclusive remedy for such Party and its Indemnity

Group after the Closing with respect to (a) the inaccuracy or breach of any representation or warranty made by another Party hereunder and (b) a breach or default in the performance by such other Party of any covenant or agreement of such other Party contained in this Agreement. Except as otherwise provided in Section 6.4. Section 8.4 and this Article IX, each Party hereby waives any Claim arising under common law, any statute, or otherwise against another Party arising from or out of the inaccuracy or breach of any representation or warranty made by the other Party hereunder or the breach or default in the performance by such other Party of any covenant or agreement of such other Party contained in this Agreement.

9.3 Indemnities of Buyer. Regardless of any investigation made at any time by or on behalf of any Party or any information any Party may have, and regardless of the presence or absence of insurance, Buyer shall indemnify and hold harmless Seller and its Indemnity Group from and against any and all Claims and Liabilities caused by, arising out of, resulting from, or relating in any way to, and to pay to Seller or its Indemnity Group any sum that Seller or its Indemnity Group pays, or becomes obligated to pay, on account of: (a) any breach or default in the performance by Buyer or Parent of any covenant or agreement of Buyer or Parent contained in this Agreement or any document executed in connection herewith; (b) any breach of a warranty or an inaccurate or erroneous representation made by Buyer or Parent in this Agreement (provided, however, that for purposes of this Section 9.3, all qualifications relating to materiality contained in such representations and warranties shall be disregarded); and (c) all Assumed Liabilities.

Regardless of any investigation made at any time by or on behalf of any Party or any information any Party may have, and regardless of the presence or absence of insurance, Seller shall indemnify and hold harmless Buyer and its Indemnity Group from and against any and all Claims and Liabilities caused by, arising out of, resulting from, or relating in any way to, and to pay Buyer or its Indemnity Group any sum that Buyer or its Indemnity Group pays or becomes obligated to pay, on account of: (a) any breach or default in the performance by Seller of any covenant or agreement of Seller contained in this Agreement or any document executed in connection herewith; (b) any breach of a warranty or an inaccurate or erroneous representation made by Seller in this Agreement (provided, however, that for purposes of this Section 9.4, all qualifications relating to materiality contained in such representations and warranties, except for Section 3.1(s), shall be disregarded); and (c) all Retained Liabilities.

9.5 Assertion of Claims; Notices; Defense; Settlement.

(a) Upon the discovery by a Party entitled to indemnification under any provision of this Agreement (the “Indemnified Party”) of facts believed to entitle such Party to indemnification hereunder, including the receipt by any such Party of notice of a Claim from any third Person, the Indemnified Party shall give prompt written notice of any such Claim to the Party obligated to provide the requested indemnification (the “Indemnifying Party”). Each such notice shall set forth the facts known to the Indemnified Party pertaining to the relevant Claim and shall specify the manner in which the Indemnified Party proposes to respond to such Claim.

(b) Within ten (10) days after the receipt by the Indemnifying Party of such notice, the Indemnifying Party shall state in writing to the Indemnified Party: (i) whether the Indemnified Party may proceed to respond to the Claim in the manner set forth in its notice, or (ii) whether the Indemnifying Party shall assume responsibility for and conduct the negotiation, defense, or settlement of the Claim, and if so, the specific manner in which the Indemnifying Party proposes to proceed. If the Indemnifying Party assumes control of the Claim, the Indemnified Party shall at all times have the right to participate in the defense thereof and to be represented, at its sole expense, by counsel selected by it. No such Claim shall be compromised or settled by either the Indemnifying Party or the Indemnified Party, as applicable, in any manner that admits liability on the part of the other Party or that might otherwise adversely affect the interest of such other Party without the prior written consent of such other Party, which consent will not be unreasonably withheld or delayed. As a condition precedent to indemnification under this Agreement, the Indemnified Party shall assign to the Indemnifying Party, and the Indemnifying Party shall become subrogated to, all rights and Claims, up to the amount of indemnification, of the Indemnified Party against third Persons arising out of or pertaining to the matters for which the Indemnifying Party shall provide indemnification. The amount of the Indemnified Party’s Claim for indemnification shall be reduced by the amount of any insurance reimbursement paid to the Indemnified Party pertaining to the Claim.

9.6 Limitation on Damages. For the breach or non-performance by any Party of any representation, warranty, covenant, or agreement contained in this Agreement, the liability of the obligor shall be limited to direct actual damages only, except to the extent that the obligee is entitled to specific performance or injunctive relief. AS BETWEEN THE PARTIES, NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, NO PARTY SHALL BE LIABLE TO ANY OTHER PARTY AS THE RESULT OF A BREACH OR A VIOLATION OF ANY REPRESENTATION, WARRANTY, COVENANT, AGREEMENT, OR CONDITION CONTAINED IN THIS AGREEMENT FOR SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR INDIRECT DAMAGES, LOST PROFITS, OR OTHER BUSINESS INTERRUPTION DAMAGES, IN TORT, IN CONTRACT, UNDER ANY INDEMNITY PROVISION, ARISING BY OPERATION OF LAW (INCLUDING, WITHOUT LIMITATION, STRICT LIABILITY), OR OTHERWISE. WITH RESPECT TO CLAIMS BY THIRD PERSONS, A PARTY MAY RECOVER FROM ANY OTHER PARTY ALL COSTS, EXPENSES, OR DAMAGES (INCLUDING, WITHOUT LIMITATION, SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR INDIRECT DAMAGES), LOST PROFITS, AND OTHER BUSINESS INTERRUPTION DAMAGES IN ADDITION TO ACTUAL DIRECT DAMAGES PAID OR OWED TO ANY SUCH THIRD PERSON IN SETTLEMENT OR SATISFACTION OF CLAIMS AS TO WHICH THE RELEVANT PARTY IS ENTITLED TO INDEMNIFICATION HEREUNDER.
