If the Parties are unable to agree on the amount due with respect to any disputed items within sixty (60) days after Seller receives Buyer’s written exceptions to the Final Settlement Statement, then the disputed items shall be exclusively and finally resolved by arbitration to be conducted in Houston, Texas, by an independent accounting firm selected by: (i) mutual agreement of Buyer and Seller; or (ii) absent such agreement, by the Houston office of the American Arbitration Association (the “ Accounting Consultant ”).

The Accounting Consultant, once appointed, shall have no ex parte communications with any of the Parties concerning the determination required hereunder. All communications between any Party and the Accounting Consultant shall be conducted in writing, with copies sent simultaneously to the other Party in the same manner, or at a meeting or conference call to which the representatives of both Parties have been invited and of which such Parties have been provided at least five (5) days’ notice. Within ten (10) days of appointment of the Accounting Consultant, each of Seller and Buyer shall present the Accounting Consultant with its position with respect to the disputed items, and all other supporting information that it desires, with a copy to the other Party.

Page 11

paid on its behalf upon receiving reasonably satisfactory evidence of such payment. However, neither Party will be obligated to reimburse the other Party for any such cost or expense (other than and excluding with respect to taxes) in excess of Ten Thousand Dollars ($10,000) unless it has been consulted about that cost or expense prior to payment.

2.4 Payment Method . Unless the Parties otherwise agree in writing, all payments under this Agreement will be by wire transfer in immediately available funds to an account designated by the Party receiving payment.

2.5 Principles of Accounting . The Preliminary Settlement Statement and Final Settlement Statement will be prepared in accordance with accounting principles generally accepted in the petroleum industry, consistently applied, and applicable laws, rules and regulations, and in all cases will include the calculation of each adjustment therein and a copy of all documentation reasonably available and necessary to support each such adjustment.

2.6 Reporting Value of the Conveyed Interests . Neither Party will take any position in preparing financial statements, reports to shareholders or Governmental Authorities, or otherwise, that is inconsistent with the allocation of value for the Conveyed Interests in Exhibit C , unless the Parties otherwise agree in writing. Exhibit C sets forth the agreed allocation of the Purchase Price among the Leases and Wells (including with respect to Target Depth(s)) for purposes of determining Purchase Price adjustments under this Agreement; the value assigned to each portion of the Conveyed Interests in Exhibit C is hereafter referred to as the “ Allocated Value ” of that portion of the Conveyed Interests.

2.7 Section 1031 Exchange . Seller and Buyer hereby agree that Buyer shall have the right at any time prior to Closing to assign all or a portion of its rights under this Agreement to a “ Qualified Intermediary ” (as that term is defined in Section 1.1031(k)-1(g)(4)(iii) of the Treasury Regulations) in order to accomplish the transaction in a manner that will comply, either in whole or in part, with the requirements of a like kind exchange pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended (the “ Code ”). Likewise, Seller shall have the right at any time prior to Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary for the same purpose. In the event a Party assigns its rights under this Agreement pursuant to this Section  2.7 , such Party agrees to notify the other Parties in writing of such assignment at or before Closing. If Seller assigns its rights under this Agreement for this purpose, Buyer agrees to: (a) consent to Seller’s assignment of its rights in this Agreement; and (b) pay the Purchase Price into a qualified escrow or qualified trust account at Closing as directed in writing. If Buyer assigns its rights under this Agreement for this purpose, Seller agrees to: (i) consent to Buyer’s assignment of its rights in this Agreement; (ii) accept the Purchase Price from the qualified escrow or qualified trust account at Closing; and (iii) at Closing, convey and assign directly to Buyer the Conveyed Interests upon satisfaction of the other conditions to Closing and other terms and conditions hereof. Seller and Buyer acknowledge and agree that any assignment of this Agreement to a Qualified Intermediary shall not release any Party from any of its respective liabilities and obligations to the other Parties under this Agreement, and that no Party represents to any other Party that any particular tax treatment will be given to a Party as a result thereof. Seller and Buyer further agree that the Party not electing to effect a like-kind exchange will not incur any additional costs, expenses, fees or liabilities as a result of or connected with the like-kind exchange and will be held

Page 12

harmless and indemnified by the Party electing to effect a like-kind exchange from and against any such additional costs, expenses, fees or liabilities. Seller and Buyer acknowledge and agree that a Party’s election to structure the transaction under this Agreement as part of a like-kind exchange shall not extend the Closing Date and, in the event that the like-kind exchange cannot be structured such that the Closing shall occur on the Closing Date, then the Closing shall occur without the transaction being structured as a like-kind exchange.

Except for Seller’s indemnification in Section  8.4.1 with respect to breaches of the representation in Section  3.2.8 and Seller’s indemnification in Section  8.4.6 , Buyer shall be deemed to have conclusively waived and assumed all liability for, and Seller shall have no liability for, all Adverse Environmental Conditions of which Seller has not been given timely notice in accordance with the requirements of this Section  5.3.3 .

5.3.4 Remedies for Adverse Environmental Conditions .

(a) Seller shall have the right, but not the obligation, to attempt, at its sole cost, to remediate to the Standard any Adverse Environmental Conditions of which it has been advised by Buyer prior to the Environmental Claim Date. Seller may elect to attempt to remediate such Adverse Environmental Conditions which are capable of being remediated until the Cure Deadline, but must provide Buyer notice of such election at least seven (7) days prior to the Closing Date.

If Seller timely elects to remediate any Adverse Environmental Condition, Buyer shall grant Seller a limited right of access as needed to complete such efforts; provided, however, that until the Adverse Environmental Condition is remediated to the Standard, Seller shall INDEMNIFY, DEFEND AND HOLD BUYER HARMLESS from and against all Claims related to such Adverse Environmental Condition, provided, further, however, that this indemnity shall terminate as to a particular Adverse Environmental Condition when the Adverse Environmental Condition is remediated to the Standard.

such Adverse Environmental Condition to the Standard; provided, that if the Environmental Defect Value exceeds the Allocated Value of the affected Conveyed Interests, either Party shall be entitled (at its sole discretion) to elect to have Seller retain the affected Conveyed Interests and reduce the Purchase Price by the Allocated Value thereof (which Purchase Price reduction for the Allocated Value of a Conveyed Interest so retained shall not be subject to the Environmental Threshold and Aggregate Deductible).

(c) Subject to Buyer’s satisfaction of the Environmental Threshold and Aggregate Deductible, for (i) each disputed Adverse Environmental Condition identified prior to the Environmental Claim Date as provided in Section  5.3.3 and (ii) each Adverse Environmental Condition which Seller elects to cure pursuant to Section  5.3.4(a) , Seller shall, without prejudice to Seller’s position as to the existence or nature of or cost to remediate such Adverse Environmental Condition, transfer the affected Conveyed Interests to Buyer at Closing and Buyer shall remit at Closing to the escrow account described in the Escrow Agreement (such account, the “ Defect Escrow ”), and the Parties shall reduce the Purchase Price at Closing by, an amount equal to Buyer’s asserted Environmental Defect Value set forth in good faith in Buyer’s notice delivered under Section  5.3.3 with respect to any Adverse Environmental Condition (such amount(s), the “ Environmental Defect Escrow Amount ”); provided, that if Buyer’s asserted Environmental Defect Value set forth in good faith in Buyer’s notice delivered under Section  5.3.3 with respect to an affected Conveyed Interest exceeds the Allocated Value of such affected Conveyed Interest, either Party shall be entitled (at its sole discretion) to elect to have Seller retain such affected Conveyed Interest at the Closing and reduce the Purchase Price by the entire Allocated Value thereof (which Purchase Price reduction for the Allocated Value of a Conveyed Interest so retained shall not be subject to the Environmental Threshold and Aggregate Deductible). To the extent at any time prior to the Cure Deadline, Seller remediates any Adverse Environmental Condition which Seller elected to remediate pursuant to Section  5.3.4(a) to the Standard, the Parties shall instruct the Escrow Agent to remit the applicable amount in the Defect Escrow to Seller within ten (10) days after Seller remediates such Adverse Environmental Condition to the Standard. To the extent Seller fails to remediate any Adverse Environmental Condition to the Standard prior to the Cure Deadline which Seller elected to remediate pursuant to Section  5.3.4(a) and Seller and Buyer have agreed on the estimated cost of remediating such Adverse Environmental Condition, the Parties shall instruct the Escrow Agent to remit the applicable amount(s) in the Defect Escrow to the applicable Party within ten (10) days after the Cure Deadline. With respect to any Conveyed Interest for which the Environmental Defect Value set forth in Buyer’s notice delivered under Section  5.3.3 exceeded the Allocated Value of such affected Conveyed Interest and was excluded from Closing by Buyer pursuant to Section  5.3.4(b) or the proviso in this Section  5.3.4(c) above and which Seller elected to remediate pursuant to Section  5.3.4(a) , if following remediation by Seller such Environmental Defect Value with respect to such affected Conveyed Interest has been remediated to an amount less than the Allocated Value of the affected Conveyed Interest, without limiting Buyer’s rights under Section  5.3.5 , (x) Seller shall execute and deliver to the Buyer an assignment (substantially in the form of the Assignment) of the Conveyed Interests affected by such cured or partially cured Adverse Environmental Condition and (y) Buyer shall contemporaneously deliver to Seller, by wire transfer in immediately available funds to Seller’s account, an amount equal to the Allocated Value of the affected Conveyed Interest less such Environmental Defect Value. Any disputes over the existence of Adverse Environmental Condition(s), the extent of remediation of Adverse Environmental Conditions or Environmental Defect Values shall be subject to resolution under Section  5.3.5 .

Page 24

(d) Notwithstanding anything to the contrary in this Section  5.3 , Buyer shall have no remedy hereunder for any Adverse Environmental Condition unless: (i) the Environmental Defect Value for such Adverse Environmental Condition exceeds Eighty Thousand Dollars ($80,000) net to Seller’s interest in the allegedly affected portion of the Conveyed Interest (the “ Environmental Threshold ”), in which event the value of such defect will be taken into account from first dollar; and (ii) the sum of the aggregate (A) Environmental Defect Values for the Adverse Environmental Conditions with Environmental Defect Values exceeding the Environmental Threshold and (B) Title Defect Values for the Title Defects with Title Defect Values exceeding the Title Defect Threshold, exceeds Eleven Million Nine Hundred Thousand Dollars ($11,900,000) (the “ Aggregate Deductible ”), and then only to the extent such amount exceeds the Aggregate Deductible; provided, however, that such limitations shall not apply with respect to any Conveyed Interests which either Party elected to have Seller retain under Section  5.3.4(b) or 5.3.4(c) due to the Environmental Defect Value being greater than the Allocated Value of the affected Conveyed Interest; and provided, further, that such Aggregate Deductible shall not apply with respect to any Title Defect constituting a Lease expiring between the Effective Time and the Closing Date that would have been prevented by the operations set forth in Schedule 10.1 . The Parties agree that if the same Adverse Environmental Condition affects more than one Conveyed Interest (e.g., systematic, similar Adverse Environmental Conditions at multiple sites, including missing Spill, Prevention, Countermeasure and Control plans at each site), then the amounts attributable to such Adverse Environmental Condition for each Conveyed Interest affected by such Adverse Environmental Condition shall be aggregated for the purposes of determining whether the Environmental Threshold has been met with respect to such Adverse Environmental Condition.

5.3.5 Adverse Environmental Condition Disputes . Without prejudice to Seller’s position as to the existence or nature of a timely and properly asserted Adverse Environmental Condition or the cost to remediate a timely and properly asserted Adverse Environmental Condition to the Standard, Seller and Buyer shall attempt to agree prior to the Closing Date on: (a) the existence of an Adverse Environmental Condition; (b) Seller’s remediation of any Adverse Environmental Condition to the Standard; and (c) the Environmental Defect Value associated with all timely and properly asserted Adverse Environmental Conditions. If Seller and Buyer are unable to agree on any of the above (collectively or individually, as applicable, the “ Disputed Environmental Matters ”) prior to the Closing Date, (i) the affected Conveyed Interests will be conveyed to Buyer at Closing, (ii) the Environmental Defect Escrow Amount will be deposited into the escrow account described in the Escrow Agreement in accordance with Section  5.3.2 , and (iii) the Disputed Environmental Matters shall be exclusively and finally resolved by expert determination to be conducted in Houston, Texas pursuant to this Section  5.3.5 . If the Parties agree on the amount due with respect to any disputed items or a final determination is made by the Environmental Consultant, and a payment adjustment is required, the Parties shall instruct the Escrow Agent to remit the applicable amount(s) in the Defect Escrow to the applicable Party within ten (10) days after the Parties reach agreement or the Environmental Consultant makes its determination. During the ten (10) day period following the Closing Date or following the Cure Deadline, as applicable, all Disputed Environmental Matters shall be submitted to an environmental consultant with at least fifteen (15) years’ experience in oil and gas environmental matters as selected by: (i) mutual agreement of Buyer and Seller; or

Page 25

(ii) absent such agreement during the ten (10) day period, by the Houston office of the American Arbitration Association (the “ Environmental Consultant ”). The Environmental Consultant shall not have been employed by any Party within the five (5) year period preceding the arbitration. The Environmental Consultant, once appointed, shall have no ex parte communications with any of the Parties concerning the determination required hereunder. All communications between any Party and the Environmental Consultant shall be conducted in writing, with copies sent simultaneously to the other Party in the same manner, or at a meeting or conference call to which the representatives of both Seller and Buyer have been invited and of which such Parties have been provided at least five (5) days’ notice. Within ten (10) days of appointment of the Environmental Consultant, each of Seller and Buyer shall present the Environmental Consultant with a written statement of its position on the Disputed Environmental Matters, including a written statement of its position with respect to any disputes regarding: (x) the existence of any properly and timely asserted Adverse Environmental Condition; (y) the proposed remediation of any properly and timely asserted Adverse Environmental Condition to the Standard; and (z) the Environmental Defect Value, in each case as applicable, together with all other supporting information that it deems relevant, with a copy to the other Party. The Environmental Consultant shall also be provided with a copy of this Agreement. Within forty-five (45) days after receipt of such materials and after receipt of any additional information required by the Environmental Consultant, the Environmental Consultant shall make his determination, which shall be final and binding upon all Parties, without right of appeal, absent manifest error. In making its determination, the Environmental Consultant shall be bound by the rules set forth in this Section  5.3 . In no event shall the Environmental Consultant select an amount higher than the amount proposed by Buyer, as applicable. The Environmental Consultant shall act as an expert for the limited purpose of determining: (A) the existence of any timely and properly asserted Adverse Environmental Condition in dispute; (B) whether any properly and timely asserted Adverse Environmental Condition has been remediated to the Standard; and (C) the specific disputed Environmental Defect Values. The Environmental Consultant may not award damages, interest or penalties to any Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Seller shall bear one-half (1/2) and Buyer shall bear one-half (1/2) of the costs and expenses of the Environmental Consultant.

5.3.6 Exclusive Remedy . The remedies set forth in this Section  5.3 and Seller’s indemnification in Section  8.4.1 with respect to breaches of the representation in Section  3.2.8 are the sole and exclusive remedies of Buyer with respect to any Adverse Environmental Condition (and all Buyer Environmental Obligations arising out of any such Adverse Environmental Condition) attributable to the ownership or operation of the Conveyed Interests by Seller or any of its Affiliates prior to the Effective Time, or the condition of the Conveyed Interests prior to the Effective Time, regardless of whether Buyer notifies Seller of any such Adverse Environmental Condition. Seller shall have no liability to Buyer for any such Adverse Environmental Condition (or its related Buyer Environmental Obligations) if Buyer fails to notify Seller as provided in Section  5.3.3 .

5.4 Bonding Requirements . Buyer agrees to promptly purchase and post any and all bonds, supplemental bonds or other securities which may be required of it pursuant to all applicable federal, state and local laws, rules and regulations.

5.5 Consents to Assign .

5.5.1 Notices to Holders .

(a) If Seller’s right to convey any of the Conveyed Interests to Buyer is subject to Third Party consents to assign or similar rights, excluding consents ordinarily obtained after Closing (collectively, “ Consents ”), then, as soon as reasonably practical after the Execution Date (unless delayed by Buyer’s review, as provided below) Seller shall: (i) notify the holders of the Consents identified on Schedule 3.2.3 that Seller intends to transfer the Conveyed Interests to Buyer; (ii) provide the holders of such Consents with any information about the transfer of the Conveyed Interests to which they are entitled; and (iii) request the holders of such Consents to consent to the assignment of the affected Conveyed Interests to Buyer. Buyer shall take all actions reasonably necessary or required to obtain such Consents.

(b) Before Closing, Seller shall notify Buyer whether: (i) any Consents are granted or denied or cannot be obtained before Closing; or (ii) the requisite time periods have elapsed and any Consents deemed given by the lapse of such requisite time periods under the applicable agreements.

5.5.2 Remedies .

(a) Consents . Before Closing, Seller shall use reasonable efforts (which shall not require the payment of money Buyer does not agree to pay, and for which Seller may not make any new commitment binding on Buyer without Buyer’s prior written consent) to obtain all Consents. If Seller is unable to obtain a Consent that (i) if not obtained by Closing, would invalidate the instrument giving rise to such Consent or (ii) if not obtained by Closing, would make the conveyance or assignment of the affected Conveyed Interests void or voidable (each, a “ Hard Consent ”), then, unless waived by both Parties, the portion of the Conveyed Interests affected by the Hard Consent shall be excluded from the Conveyed Interests delivered at Closing and the Purchase Price shall be adjusted downward by the Allocated Value of such Conveyed Interests; provided, however, that Seller shall have the option to elect in writing at any time prior to the Final Settlement Date to instead exclude such Conveyed Interests from the Conveyed Interests delivered at Closing with no adjustment to the Purchase Price (such excluded Conveyed Interests the “ Delayed Conveyed Interests ”) under and in accordance with Section  5.5.2(c) . If Seller is unable to obtain any Consent that is not a Hard Consent, then Seller and Buyer shall proceed to Closing as to the portion of the Conveyed Interests affected by such un-obtained Consent without adjustment to the Purchase Price, subject to the further obligations of Seller and Buyer set forth in this Section  5.5.2(a) . After Closing, Seller shall use commercially reasonable efforts to obtain any un-obtained Consents (which shall not require the payment of money Buyer does not agree to pay), including Consents alleged by Third Parties or identified after Closing, and Buyer shall provide reasonable assistance to Seller. If Seller is able to obtain a Hard Consent prior to the Final Settlement Date, then Buyer shall pay to Seller the Allocated Value of such Conveyed Interests excluded from the Closing and the Conveyed Interests affected by such Hard Consent shall be transferred to Buyer pursuant to an assignment in the form of Exhibit D or Exhibit E , as applicable. If Seller is unable to obtain a Hard Consent on or before the Final Settlement Date, then Seller shall retain ownership of the affected portion of the Conveyed Interests. If Seller is unable to obtain a Consent that is not a Hard Consent on or before the Final Settlement Date, then Buyer shall retain ownership of the affected portion of the Conveyed Interests.

Page 27

(b) Limitation of Liability . Except to the extent that Buyer can establish that Seller failed to fulfill the obligations set forth above in this Section  5.5 , Buyer shall DEFEND, INDEMNIFY AND HOLD SELLER HARMLESS from and against all Claims, actions, causes of action whatsoever that arise out of the failure to obtain any Consents that are not Hard Consents with respect to any transfer by Seller to Buyer of any portion of the Conveyed Interests WHETHER OR NOT SUCH CLAIMS, ACTIONS OR CAUSES OF ACTION ARISE OUT OF THE NEGLIGENCE OF SELLER (INCLUDING SELLER’S SOLE, SIMPLE, CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF SELLER.

(c) Delayed Conveyed Interests . With respect to any Delayed Conveyed Interests, Seller shall hold such Delayed Conveyed Interest separate and for the use and benefit, to the extent it has the legal right to do so, of Buyer (at the expense of Seller). In addition, to the extent permitted by Law and to the extent otherwise permissible in light of any approval or consent requirement, Seller shall take such other reasonable actions (including those reasonably requested by Buyer) to place Buyer, to the extent it has the legal right to do so, in the same position as if such Delayed Conveyed Interest had been transferred, assigned, or conveyed as contemplated hereby and so that all the benefits and burdens relating to such Delayed Conveyed Interest, including possession, use, risk of loss, potential for gain, and dominion, control, and command over such asset, are to inure from and after the Closing Date to Buyer. To the extent permitted by Law and to the extent otherwise permissible in light of any approval or consent requirement, Buyer shall be entitled to, and shall be responsible for, the management and the benefits and burdens of any Delayed Conveyed Interest not yet transferred to it as a result of this Section  5.5.2(c) . If and when such amendments, consents or approvals are obtained, then the transfer of the applicable Delayed Conveyed Interest shall be promptly effected in accordance with the terms of this Agreement, without the payment of additional consideration pursuant to an assignment in the form of Exhibit D or Exhibit E , as applicable.

5.6 Title Defects .

5.6.1 Certain Definitions .

(a) Title Defects . For the purposes of this Agreement, a “ Title Defect ” means, to the extent related to the Conveyed Interest (and without duplication of any reduction in Allocated Value), (A) with respect to each Lease that is not held by production or otherwise maintained in force, such Lease having a primary term expiration date more than seven (7) days earlier than the primary term expiration date set forth on Exhibit A , Schedule 1 with respect to such Lease, unless such primary term expiration date is more than nine (9) months subsequent to the Target Closing Date, (B) with respect to any Lease, where the satisfaction of the continuous drilling obligation under such Lease (or the satisfaction of the drilling obligation under the applicable pooling agreement or the satisfaction of the requirements of Title 31, Chapter 9, Sections 9.34(b), (c)(1), or (d) of the Texas Administrative Code) does not operate to maintain and hold Seller’s title or interest in and to the applicable Target Depth set forth in Exhibit A , Schedule 1 with respect to such Lease, (C) with respect to any horizontal Well treated or classified as an allocation well that crosses more than one Lease or leasehold tract, any instance where Seller has remitted proceeds of production to a third party without the benefit of either a production sharing agreement or division order executed by such third party and (D) any (1) lien

Page 28

or security interest affecting Seller’s title or interest in the Conveyed Interests; or (2) impairment, encroachment, irregularity, defect in or dispute concerning Seller’s title to the Conveyed Interests that would:

(i) reduce Seller’s net revenue interest in the currently producing formations of any Well (as such currently producing formations is set forth on in Exhibit A , Schedule 2 with respect to each Well) below that net revenue interest set forth for such Well in Exhibit A , Schedule 2 with respect to such currently producing formations;

(ii) increase Seller’s working interest (X) in any Lease above that set forth for the Target Depth in Exhibit A , Schedule 1 with respect to such Lease or (Y) in the currently producing formations of any Well (as such currently producing formations is set forth on in Exhibit A , Schedule 2 with respect to each Well) above that set forth for such Well in Exhibit A , Schedule 2 with respect to such currently producing formations, in each case of (X) or (Y) without a corresponding and at least a proportionate increase in Seller’s net revenue interest;

(iii) reduce the number of net mineral acres attributable to Seller’s interest in a Lease, insofar as such Lease affects the Target Depth, below that set forth in Exhibit A , Schedule 1 with respect to such Lease and Target Depth;

(iv) reduce Seller’s net revenue interest in a Lease, insofar as such Lease affects the Target Depth, below that set forth in Exhibit A , Schedule 1 with respect to such Lease and Target Depth; or

For purposes of this Section  5.6 , the “ Target Depth ” shall refer to those certain depths described on Exhibit A , Schedule 1 for the Leases. For purposes of this Section  5.6 , a “ net mineral acre ” shall mean as to each parcel or tract of land burdened by a Lease, the product of (a) the number of acres of land that are in such parcel or tract (i.e., gross acres), multiplied by (b) the lessor’s undivided interest in the lands covered by such Lease, multiplied by (c) the Seller’s undivided interest in such Lease (provided, however, if items (b) and (c) of the definition vary as to different areas within any tracts or parcels burdened by such Lease, a separate calculation shall be performed with respect to each such area). Notwithstanding the foregoing, the following shall not be considered Title Defects: (1) any matter based solely on lack of information or documents in Seller’s files; (2) any failure to record state or federal Leases or assignments thereof in county records; (3) any Adverse Environmental Condition, Production Imbalances, Permitted Encumbrance or Consents; (4) defects arising out of lack of survey; (5) the treatment or classification of any horizontal well as an allocation well that crosses more than one Lease or leasehold tract, including (i) the failure of such Leases or leasehold tracts as to such well to be subject to a production sharing agreement or similar agreement, whether in whole or in part and (ii) the allocation of Hydrocarbons produced from such well among such Leases or leasehold tracts based upon the length of the “as drilled” horizontal wellbore open for production, the total length of the horizontal wellbore, or other methodology that is intended to reasonably attribute to each such Lease or leasehold tract its share of such production, except, as to both (i) and (ii), to the extent that Seller has remitted proceeds of production to a third party without the benefit of

Page 29

either a production sharing agreement or a division order executed by such third party; (6) defects that have been cured or remedied by applicable laws of limitations or prescription; (7) any reductions in net revenue interest to reflect changes that accompany the formation of units in accordance with the covenants relating to the interim period in Section  10.1 , except with respect to Leases in Units of a Well drilled by Seller or that is commenced or scheduled to be commenced prior to the Closing Date; and (8) defects in the chain of title consisting of the mere failure to recite marital status in a document or omissions of successions of heirship or estate proceedings.

(b) Permitted Encumbrances . The term “ Permitted Encumbrance ” means:

(i) any materialmans’, mechanics’, repairmans’, employees’, contractors’, operators’ or other similar liens, security interests or charges for liquidated amounts arising in the ordinary course of business incidental to construction, maintenance, development, production or operation of the Conveyed Interests, or the production or processing of Hydrocarbons therefrom, that are not delinquent or, if delinquent, are being contested in good faith;

(ii) any liens for taxes not yet delinquent or, if delinquent, that are being contested in good faith by appropriate proceedings and for which adequate reserves have been established in accordance with generally accepted accounting principles;

(iii) any liens or security interests created in the Leases for royalty, bonus or rentals, in each case, to the extent any such amounts are currently unpaid and the net cumulative effect of such burdens do not operate to (A) interfere in any material respect with Buyer’s ownership or operation of the portion of the Conveyed Interests burdened thereby as currently operated, (B) reduce the net revenue interest of Buyer in all or a portion of the Conveyed Interests below that specified in the applicable Schedule to Exhibit A or increase the working interest of Buyer in all or a portion of the Conveyed Interests above that specified in the applicable Schedule to Exhibit A without a corresponding and at least proportionate increase in net revenue interest, (C) reduce Seller’s net revenue interest in a Lease below that set forth in Exhibit A , Schedule 1 or (D) reduce Seller’s net mineral acres in a Lease below that set forth in Exhibit A , Schedule 1 ;

(iv) any easements, rights-of-way, servitudes, permits, licenses, surface leases and other rights with respect to surface operations, to the extent such matters do not interfere in any material respect with Seller’s ownership or operation of the portion of the Conveyed Interests burdened thereby;

(v) all royalties, overriding royalties, net profits interests, carried interests, reversionary interests and other, in each case, that are of record and to the extent the net cumulative effect of such burdens do not operate to (A) interfere in any material respect with Buyer’s ownership or operation of the portion of the Conveyed Interests burdened thereby as currently operated, (B) reduce the net revenue interest of Buyer in all or a portion of the Conveyed Interests below that specified in the applicable Schedule to Exhibit A or increase the working interest of Buyer in all or a portion of the Conveyed Interests above that specified in

Page 30

the applicable Schedule to Exhibit A without a corresponding and at least proportionate increase in net revenue interest, (C) reduce Seller’s net revenue interest in a Lease below that set forth in Exhibit A , Schedule 1 or (D) reduce Seller’s net mineral acres in a Lease below that set forth in Exhibit A , Schedule 1 ;

(vi) excepting circumstances where such rights have already been triggered, conventional rights of reassignment arising upon surrender or abandonment of any Conveyed Interests;

(vii) rights reserved to or vested in any Governmental Authority to control or regulate any of the Wells and all applicable laws, rules, regulations and orders of such authorities, in each case, to the extent the net cumulative effect of such burdens do not operate to (A) interfere in any material respect with Buyer’s ownership or operation of the portion of the Conveyed Interests burdened thereby as currently operated, (B) reduce the net revenue interest of Buyer in all or a portion of the Well below that specified in the applicable Schedule to Exhibit A or increase the working interest of Buyer in all or a portion of the Conveyed Interests above that specified in the applicable Schedule to Exhibit A without a corresponding and at least proportionate increase in net revenue interest or (C) reduce Seller’s net revenue interest in a Lease below that set forth in Exhibit A , Schedule 1 .

(viii) any other liens, charges, encumbrances, obligations, discrepancies or other defects in Seller’s title which do not, individually or in the aggregate, detract from the value of or interfere with the use or ownership of the Conveyed Interests subject thereto or affected thereby and which would be accepted by a reasonable and prudent operator of oil and gas properties in the same region in which the Conveyed Interest is located;

(ix) any defects or irregularities in acknowledgements;

(x) any defects and irregularities arising out of the lack of recorded powers of attorney from individuals, corporations or partnerships to execute and deliver documents on their behalf;

(xi) defects or irregularities resulting solely from prior oil and gas leases, which, on their face, expired more than ten (10) years ago;

(xii) any defects, irregularities or clouds on title, which may arise as a result of a stranger to title or scrivener’s error in a duly recorded deed or instrument;

(xiii) defects or irregularities arising out of mortgages, deeds of trust, and other encumbrances, which, by their terms, matured more than ten (10) years ago, but which have not been released of record;

(xiv) defects or irregularities in title, which, for a period of twenty-five (25) years or more have not delayed or prevented Seller (or its predecessors) from receiving its net revenue interest share of the proceeds of production from any Well or Lease;

Page 31

(xvi) any defects or irregularities arising prior to 1960; or

The term “ Title Benefit ” means any right, circumstance or condition that operates (i) to increase Seller’s net revenue interest in any Well or Lease above that set forth in Exhibit A , Schedule 1 or Exhibit A , Schedule 2 , as applicable, and in the case of a Well, without causing a greater than proportionate increase in Seller’s working interest or (ii) increases the number of net mineral acres attributable to any Lease above that set forth in Exhibit A , Schedule 1 .

5.6.2 Notice of Title Defects and Title Benefits; Defect and Benefit Adjustments .

(a) Buyer will review title to the Wells and Leases prior to Closing and notify Seller in writing of any Title Defect it discovers as soon as reasonably practicable after its discovery, but in no event later than the date that is thirty (30) days after the Execution Date (the “ Title Claim Date ”). To be effective, such notice shall be in writing and shall include: (i) a detailed description of the alleged Title Defect(s); (ii) the Well or Lease affected; (iii) the Allocated Value of the Well or Lease subject to the alleged Title Defect(s); (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of the alleged Title Defect(s); and (v) the amount by which Buyer reasonably believes the Allocated Value of the affected Well or Lease is reduced by the alleged Title Defect(s) and the computations and information upon which Buyer’s belief is based. Buyer shall be deemed to have conclusively waived, and Seller shall have no liability for, all Title Defects of which Seller has not been given timely notice on or before the Title Claim Date in accordance with the requirements of this Section  5.6.2 .

(b) Should Buyer discover any Title Benefit on or before the Title Claim Date, Buyer shall, as soon as practicable, but in any case no later than the Title Claim Date, deliver to Seller a notice including: (i) a detailed description of the Title Benefit(s); (ii) the Well or Lease affected; (iii) the Allocated Value of the Well or Lease subject to such Title Benefit(s); and (iv) the amount by which Buyer reasonably believes the Allocated Value of the affected Well or Lease is increased by the Title Benefit(s) and the computations and information upon which Buyer’s belief is based. Subject to the limitations set forth in Section  5.6.2(e) below, Seller shall have the right, but not the obligation, to deliver to Buyer a similar notice on or before the Cure Deadline; provided, that with respect to Title Benefits related to Conveyed Interests for which Buyer asserts a claim under the Special Warranty, Seller shall have the right, but not the obligation, to deliver to Buyer such notice within a reasonable period following the assertion of such claim.

(c) Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove any Title Defects of which it has been advised by Buyer prior to the Title Claim Date. Seller may elect to attempt to cure such Title Defect until the day that is one hundred and ten (110) days after Closing (the “ Cure Deadline ”), but must provide Buyer notice of such election at least seven (7) days prior to the Closing Date. Seller’s election to attempt to cure a Title Defect shall not constitute a waiver of Seller’s right to dispute the existence, nature or value of, or cost to cure, the Title Defect.

Page 32

(d) Seller’s interest in each Well or Lease affected by Title Defects properly reported under Section  5.6.2(a) and not cured prior to the Closing Date shall be assigned to Buyer at Closing subject to all such uncured Title Defects. If Seller has not provided notice under Section  5.6.2(c) of its election to attempt to cure a Title Defect and such Title Defect is not disputed, the Purchase Price shall be adjusted by an amount (the “ Title Defect Value ”) equal to the reduction in the Allocated Value for the affected Well or Lease caused by such Title Defect, as determined pursuant to Section  5.6.2(f) , subject to Section  5.6.2(h) . If Seller has provided such notice under Section  5.6.2(c) or with respect to any disputed Title Defect, Seller shall, without prejudice to Seller’s position as to the existence or nature of or ability to cure such Title Defect, transfer the affected Conveyed Interests to Buyer at Closing and Buyer shall remit at Closing to the Defect Escrow, and the Parties shall reduce the Purchase Price at Closing by, Buyer’s asserted Title Defect Value set forth in good faith in Buyer’s notice delivered under Section  5.6.2(a) with respect to any such Title Defects (such amount(s), the “ Title Defect Escrow Amount ”, and together with the Environmental Defect Escrow Amount, if any, the “ Defect Escrow Amount ”). To the extent at any time prior to the Cure Deadline, Seller cures any Title Defect which Seller elected to cure pursuant to Section  5.6.2(c) , the Parties shall instruct the Escrow Agent to remit the applicable amount in the Defect Escrow to Seller within ten (10) days after Seller cures such Title Defect. To the extent Seller fails to cure any Title Defect prior to the Cure Deadline which Seller elected to cure pursuant to Section  5.6.2(c) and Seller and Buyer have agreed on the Title Defect Values for such Title Defects, the Parties shall instruct the Escrow Agent to remit the applicable amount(s) in the Defect Escrow to the applicable Party within ten (10) days after the Cure Deadline. Any disputes over the existence of Title Defect(s), the extent of cure of Title Defects or Title Defect Values shall be subject to resolution under Section  5.6.2(h) . Should the cumulative Title Defect Value with respect to any Well or Lease equal the entire Allocated Value for the affected Conveyed Interest, then (i) if, after taking such Title Defect Value into account, the Aggregate Deductible has not been exceeded as provided in Section  5.6.2(f)(ix) , Buyer may, within ten (10) days of any such determination, elect to (A) retain such Well or Lease or (B) reconvey to Seller all of its rights with respect to such Well or Lease by conveyance without warranty (other than a special warranty of title by, through or under Buyer, but not otherwise) and, for the avoidance of doubt, without any reduction in the Purchase Price and (ii) if, after taking such Title Defect Value into account, the Aggregate Deductible has been exceeded as provided in Section  5.6.2(f)(ix) , Buyer shall, within ten (10) days of any such determination, reconvey to Seller all of its rights with respect to such Well or Lease by conveyance without warranty (other than a special warranty of title by, through or under Buyer, but not otherwise) and the Purchase Price shall be decreased in the Final Settlement by the entire Allocated Value for such reconveyed Well or Lease, subject to the application of Section  5.6.2(f)(ix) .

(e) With respect to each Well or Lease affected by Title Benefits reported by Buyer or Seller prior to the Cure Deadline (or of which Buyer had knowledge and should have reported under Section  5.6.2(b) ) an amount equal to the increase in the Allocated Value for such Well or Lease caused by such Title Benefits, as determined pursuant to Section  5.6.2(g) (the “ Title Benefit Value ”) shall only be used to reduce the amount of aggregate Title Defect Value attributable to Title Defects properly and timely raised by Buyer after taking into account the Title Defect Threshold and shall not be used to increase the Purchase Price.

Page 33

(f) The Title Defect Value resulting from a Title Defect shall be determined as follows:

(i) if Buyer and Seller agree in writing on the Title Defect Value, that amount shall be the Title Defect Value;

(ii) if the Title Defect is a lien, encumbrance or other charge which is undisputed and liquidated in amount, then the Title Defect Value shall be the amount necessary to be paid to remove the Title Defect from the Conveyed Interest in the affected Well or Lease;

(iii) if the Title Defect is of the type described in Section  5.6.1(a)(i) , then the Title Defect Value shall be an amount equal to the Allocated Value for such Well, multiplied by the proportionate reduction in such net revenue interest (i.e., the amount by which the share of production to which Seller is actually entitled is less than the net revenue interest set forth for such Well on Exhibit A , Schedule 2 , divided by such net revenue interest set forth on Exhibit A , Schedule 2 ), provided, however, that if the Title Defect does not affect such Well throughout the entire remaining life of such Well, the defect amount determined shall be reduced to take into account the applicable time period only;

(iv) if the Title Defect is of the type described in Section  5.6.1(a)(ii) , then the Title Defect Value shall be an amount equal to the diminution in value of such Well based on the Allocated Value for such Well and resulting from the increase in such working interest over the life of the Well;

(v) if the Title Defect is of the type described in Section  5.6.1(a)(iii) , then the Title Defect Value shall be an amount equal to the product of (y) the Allocated Value of such Lease multiplied by (z) one (1), minus a fraction, the numerator of which is the actual net mineral acres covered by such Lease (with respect to the Target Depth) and the denominator of which is the net mineral acres for such Lease (with respect to the Target Depth) set forth in Exhibit A , Schedule 1 ;

(vi) if the Title Defect is of the type described in Section  5.6.1(a)(iv) , then the Title Defect Value shall be an amount equal to the product of (y) the Allocated Value of such Lease multiplied by (z) one (1), minus a fraction, the numerator of which is the actual net revenue interest for such Lease (with respect to the Target Depth) and the denominator of which is the net revenue interest for such Lease (with respect to the Target Depth) set forth in Exhibit A , Schedule  1 ;

(vii) if a Title Defect is based on a Lease having a primary term expiration date (a) more than seven (7) days earlier than the primary term expiration date set forth on Exhibit A , Schedule 1 with respect to such Lease and (b) that is nine (9) months or less after the Target Closing Date, then the Title Defect Value shall be equal to (i) the Allocated Value of such Lease, multiplied by (ii) a fraction, (A) the numerator of which is equal to the difference between (x) the number of days between the Execution Date and the expiration date set forth on Exhibit A , Schedule 1 and (y) the number of days between the Execution Date and

Page 34

the actual expiration date, and (B) the denominator of which is the number of days between the Execution Date and the expiration date set forth on Exhibit A (which Purchase Price reduction for any Title Defect constituting a Lease expiring between the Effective Time and the Closing Date that would have been prevented by the operations set forth in Schedule 10.1 shall not be subject to the Title Defect Threshold and Aggregate Deductible); provided, however, that if there is a Lease with a primary term expiration date that is both (i) more than seven (7) days earlier than the primary term expiration date set forth on Exhibit A , Schedule 1 with respect thereto and (ii) less than nine (9) months from the Target Closing Date, the Buyer may elect, in its sole option, to exclude such Lease hereunder and reassign to the Seller or cause the Seller to retain, the entirety of such Lease together with all Conveyed Interests solely associated therewith, and the Purchase Price shall be reduced by an amount equal to the Allocated Value (which Purchase Price reduction for any Title Defect constituting a Lease expiring between the Effective Time and the Closing Date that would have been prevented by the operations set forth in Schedule 10.1 shall not be subject to the Title Defect Threshold and Aggregate Deductible) of such Lease (and, for all purposes under this Agreement other than in this sentence, such Lease and associated Conveyed Interests shall be deemed Excluded Assets);

(viii) if the Title Defect is of a type not described above, then, in each case, the Title Defect Value shall be determined by taking into account the Allocated Value of the Well or Lease (or Target Depth with respect thereto) so affected, the portion of the Conveyed Interest in such Well or Lease (or Target Depth with respect thereto) affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the affected Well or Lease (or Target Depth with respect thereto), the values placed upon the Title Defect by Buyer and Seller and such other factors as are necessary to make a proper evaluation; and

(ix) notwithstanding anything to the contrary in this Section  5.6 , Buyer shall have no remedy hereunder for any Title Defect unless: (A) the Title Defect Value for such Title Defect exceeds Sixty Thousand Dollars ($60,000) net to Seller’s interest in the relevant Well or Lease (the “ Title Defect Threshold ”), in which event the value of such defect will be taken into account from first dollar; and (B) the sum of the aggregate (1) Environmental Defect Values for the Adverse Environmental Conditions with Environmental Defect Values exceeding the Environmental Threshold and (2) Title Defect Values for Title Defects with Title Defect Values exceeding the Title Defect Threshold, exceeds the Aggregate Deductible, and then only to the extent such amount exceeds the Aggregate Deductible; provided, however, that such limitation shall not apply with respect to any Title Defect constituting a Lease expiring between the Effective Time and the Closing Date that would have been prevented by the operations set forth in Schedule 10.1 . The Parties agree that if the same Title Defect affects more than one Conveyed Interest, then the amounts attributable to such Title Defect for each Conveyed Interest affected by such Title Defect shall be aggregated for the purposes of determining whether the Title Defect Threshold has been met with respect to such Title Defect.

(g) The Title Benefit Value for any Title Benefit shall be determined as follows:

(i) if Buyer and Seller agree on the Title Benefits Amount, that amount shall be the Title Benefit Value; or

(ii) for any other Title Benefits with respect to a Conveyed Interest the Title Benefit Value shall be determined by taking into account the Allocated Value of the Well or Lease so affected, the portion of Seller’s interest in the Well or Lease affected by the Title Benefit (and the resulting portion of the Conveyed Interest affected by the Title Benefit), the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of the affected Well or Lease, the values placed upon the Title Benefit by Buyer and Seller and such other factors as are necessary to make a proper evaluation.

If Seller and Buyer are unable to agree by that date, (i) the affected Conveyed Interests will be conveyed to Buyer at Closing, (ii) the Title Defect Escrow Amount will be deposited into the escrow account described in the Escrow Agreement in accordance with Section  5.6.2(d) and (iii) the Title Defect Values and Title Benefit Values in dispute shall be exclusively and finally resolved by expert determination to be conducted in Houston, Texas pursuant to this Section  5.6.2(h) .

If the Parties agree on the amount due with respect to any disputed items or a final determination is made by the Title Consultant, and a payment adjustment is required, the Parties shall instruct the Escrow Agent to remit the applicable amount(s) in the Defect Escrow to the applicable Party within ten (10) days after the Parties reach agreement or the Title Consultant makes its determination.

The Title Consultant shall not have been employed by any Party within the five (5) year period preceding the arbitration. The Title Consultant, once appointed, shall have no ex parte communications with any of the Parties concerning the determination required hereunder. All communications between any Party and the Title Consultant shall be conducted in writing, with copies sent simultaneously to the other Party in the same manner, or at a meeting or conference call to which the representatives of both Seller and Buyer have been invited and of which such Parties have been provided at least five (5) days’ notice. Within ten (10) days of appointment of the Title Consultant, each of Seller and Buyer shall present the Title Consultant with its claim notice or its response, as applicable, and all other supporting information that it desires, with a copy to the other Party. The Title Consultant shall also be provided with a copy of this Agreement. Within forty-five (45) days after receipt of such materials and after receipt of any additional information required by the Title Consultant, the

Page 36

Title Consultant shall make its determination, which shall be final and binding upon all Parties, without right of appeal, absent manifest error. In making his determination, the Title Consultant shall be bound by the rules set forth in this Section  5.6 . In no event shall any Title Defect Value exceed the estimate given by Buyer in its claim notice delivered in accordance with Section  5.6.2(a) , and in no event shall any Title Benefit Value exceed any estimate given by Seller or Buyer in a claim notice delivered in accordance with Section  5.6.2(b) .

This confidentiality obligation shall be effective until the Closing Date. If Closing does not occur, the confidentiality obligation shall continue indefinitely and Buyer shall provide any remaining copies of the Title Diligence Results to Seller or promptly destroy such copies. If Closing does occur, this confidentiality obligation shall apply mutatis mutandis to Seller, the Title Diligence Results shall be deemed the property of the Buyer, and Seller shall provide any remaining copies of the Title Diligence Results to Buyer or promptly destroy such copies; provided, that Seller shall be permitted to use such information for purposes consistent with this Section  5.6 .

5.6.3 Exclusive Remedy .

Notwithstanding the foregoing, no individual matter described above shall be deemed to be or constitute a Casualty Loss unless the estimate of the cost required to repair or replace that portion of the Subject Property affected by the Casualty Loss exceeds Seventy-Five Thousand Dollars ($75,000.00), net to Seller’s interest in the affected portion of the Subject Property, and no Casualty Loss will be considered a Title Defect under Section  5.6 .

Page 37

5.7.2 Remedies for Casualty Losses . With respect to each Casualty Loss to the Conveyed Interests, Seller and Buyer will have the following rights and remedies:

(a) The Parties will proceed with Closing and Seller and Buyer shall mutually agree to either: (i) to make a downward adjustment to the Purchase Price by the lower of the cost of the Casualty Loss or the Allocated Value of the Conveyed Interests, or (ii) to cause the portion of the Conveyed Interests affected by the Casualty Loss to be repaired or replaced, at Seller’s cost, as promptly as reasonably practicable (which work may extend after the Closing Date), or (iii) to have Seller indemnify Buyer through a document reasonably acceptable to Seller and Buyer against actual costs or expenses that Buyer reasonably incurs to repair or replace the portion of the Conveyed Interests affected by the Casualty Loss, such amount not to exceed the Allocated Value for such Conveyed Interests; provided, however, that if Seller and Buyer cannot mutually agree on one of options (i), (ii) or (iii) of this Section  5.7.2(a) , the Parties shall be deemed to have chosen option (i).

(b) In addition to the remedies set forth in Section  5.7.2(a) , Seller and Buyer will have the termination rights in connection with Casualty Losses set forth in Section  5.8 .

None of the events or conditions set forth in this Section  5.7.4 will be considered a Casualty Loss or Title Defect with respect to the Conveyed Interests, nor will they be cause for any other reduction in the Purchase Price, or give rise to any right to terminate this Agreement.

5.8 Termination Due to Impairments to the Conveyed Interests . If the Allocated Value of all Conveyed Interests to be excluded from the transaction contemplated by this Agreement due to (a) Title Defects and Adverse Environmental Conditions which were timely asserted by Buyer and which remain uncured at Closing and (b) any Casualty Loss, exceeds, in the aggregate, twenty percent (20%) of the unadjusted Purchase Price, then either Seller or Buyer may terminate this Agreement, and neither Party will have any further obligation to conclude the transfer of the Conveyed Interests under this Agreement; provided, however, that Buyer’s indemnity obligations under Sections 5.2 , Section  8.3.3, Section  8.3.4, Section  8.3.6 and Section  11.3 shall survive such termination.

8.5.1 For purposes of this ARTICLE 8 , the term “ Indemnifying Party ” when used in connection with particular Claims means (a) Seller in the event any member of the Buyer Group is entitled to indemnification under this Agreement and (b) Buyer in the event any member of the Seller Group is entitled to indemnification under this Agreement. For purposes of this ARTICLE 8 , the term “ Indemnified Person ” when used in connection with particular Claims means (i) Buyer in the event any member of the Buyer Group is entitled to indemnification under the Agreement and (ii) Seller in the event any member of the Seller Group is entitled to indemnification under this Agreement.

8.5.2 To make a claim for indemnification, defense or reimbursement under this ARTICLE 8 , an Indemnified Person shall notify the Indemnifying Party of its claim, including the specific details (including supporting documentation in such Indemnified Person’s possession or control of the alleged Claims and such Indemnified Person’s good faith estimate of the applicable claim) of and specific basis under this Agreement for its claim (the “ Claim Notice ”).

8.5.3 In the event that any claim for indemnification set forth in any Claim Notice is based upon a claim by a Third Party against the Indemnified Person (a “ Third Party Claim ”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person 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 in such Indemnified Person’s possession or control; provided that the failure of any Indemnified Person to give notice of any Third Party Claim as provided in this Section  8.5.3 shall not relieve the Indemnifying Party of its obligations under this ARTICLE 8 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 prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an alleged inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was allegedly inaccurate or breached.

8.5.4 In the case of a claim for indemnification based upon any Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Third Party Claim under this ARTICLE 8 . The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer

Page 50

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. If the Indemnifying Party fails to notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Party admits or denies its obligation to defend the Indemnified Person, then until such date as the Indemnifying Party admits or it is finally determined by a non-appealable judgment that such right or obligation exists, the Indemnified Person may file any motion, answer or other pleading, settle any Third Party Claim or take any other action that the Indemnified Person deems necessary or appropriate to protect its interest, regardless of whether the Indemnifying Party is prejudiced or adversely impacted by any such actions.

8.5.5 If the Indemnifying Party admits its indemnity obligations under this ARTICLE 8 with respect to any Third Party Claim, then such Indemnifying Party shall have (i) the right and obligation to diligently prosecute and control the defense, at its sole cost and expense, of the Third Party Claim and (ii) full control of such defense and proceedings, including any compromise or settlement thereof unless the compromise or settlement includes the payment of any amount by, the performance of any obligation by, or the limitation of any right or benefit of, the Indemnifying Party, in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall not be unreasonably withheld or delayed. If requested by the Indemnifying Party, the Indemnified Person agrees at the cost and expense of the Indemnifying Party to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest; provided , however , that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person. The Indemnified Person may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section  8.5.5 , provided that the Indemnified Person may file initial pleadings as described in the last sentence of Section  8.5.4 above if required by court or procedural rules to do so within the thirty (30) day period in Section  8.5.4 above. An Indemnifying Party shall not, without the written consent of the Indemnified Person, settle any Third Party Claim or consent to the entry of any judgment with respect thereto that (A) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Party Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Third Party Claim) or (B) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

8.5.6 If the Indemnifying Party does not admit its obligation or admits its obligation but fails to diligently defend or settle the Third Party Claim, then the Indemnified Person shall have the right, but not the obligation, to defend and control the defense against the Third Party Claim (at the sole cost and expense of the Indemnifying Party, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Party to admit its obligation to indemnify the Indemnified Person 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 the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its obligation for indemnification with respect to such Third Party Claim and (ii) if its obligation is so admitted, assume the defense of the Third Party Claim, including the power to reject the proposed

Page 51

settlement. If the Indemnified Person settles any Third Party Claim over the objection of the Indemnifying Party after the Indemnifying Party has timely admitted its obligation for indemnification in writing and assumed the defense of the Third Party Claim, the Indemnified Person shall be deemed to have waived any right to indemnity with respect to the Third Party Claim.

8.5.7 In the case of a claim for indemnification not based upon an Third Party Claim (a “ Direct Claim ”), such Direct Claim shall be asserted by giving the Indemnifying Party reasonably prompt Claim Notice thereof, but in any event not later than thirty (30) days after the Indemnified Person becomes aware of the events that gave rise to such Direct Claim. Such Claim Notice by the Indemnified Person shall describe the Direct Claim in reasonable detail, shall include copies of all available material written evidence in such Indemnified Person’s possession or control thereof and shall indicate the estimated amount, if reasonably practicable, of Claims that have been or may be sustained by the Indemnified Person. The Indemnifying Party shall have sixty (60) days from its receipt of the Claim Notice to (i) cure the Claims complained of, (ii) admit its obligation to provide indemnification with respect to such Claims or (iii) dispute the claim for such Claims. If the Indemnifying Party does not notify the Indemnified Person within such sixty (60) day period that it has cured the Claims or that it disputes the claim for such Claims, the Indemnifying Party shall be conclusively deemed obligated to provide indemnification hereunder with respect to such Direct Claim.

Page 54

personal property taxes, and similar obligations assessed on the Subject Property, including any interest, penalties or other additions thereto (“ Property Taxes ”), and (ii) sales, use, transfer, excise and similar taxes associated with the acquisition, ownership, operation or disposition any of the Subject Property, including any interest, penalties or other additions thereto but not including taxes allocated in Section  9.5 (“ Excise Taxes ”), are Seller’s obligation for tax periods (or portions thereof) ending before the Effective Time and Buyer’s obligation for tax periods (or portions thereof) beginning on or after the Effective Time.

If Property Taxes attributable to the Conveyed Interests and/or Excise Taxes attributable to the Conveyed Interests for the current tax period have not been assessed and paid by Seller as of the Closing Date, the Buyer shall file any required Returns incident to such Property Taxes and Excise Taxes that have not been filed with respect to such period and pay to the relevant Governmental Authority such Property Taxes and Excise Taxes for the current tax year and subsequent periods. Seller will reimburse Buyer for Seller’s proportionate share of such taxes, prorated in accordance with this Section  9.2 , as a Downward Adjustment to the Purchase Price pursuant to Section  2.2.3 (based on a good faith estimate of such taxes) with a final adjustment upon Seller’s receipt of evidence of the Buyer’s payment of such taxes. If Property Taxes attributable to the Conveyed Interests and/or Excise Taxes attributable to the Conveyed Interests for the current period year have been assessed and paid by the Seller as of the Closing Date, the Buyer will reimburse the Seller for its proportionate share of such taxes, prorated in accordance with this Section  9.2 , as an Upward Adjustment to the Purchase Price, as provided in Section  2.2.2 .

9.3 Severance Taxes . Seller shall bear and pay all severance or other taxes measured by Hydrocarbon production from the Subject Property, or the receipt of proceeds therefrom, including any interest, penalties or other additions thereto (“ Severance Taxes ”), to the extent attributable to production from the Conveyed Interests before the Effective Time.

Seller shall withhold and pay on behalf of Buyer all such taxes on production from the Conveyed Interests between the Effective Time and the Closing Date (if the Closing Date follows the Effective Time), and the amount of any such payment shall be reimbursed to Seller as an Upward Adjustment to the Purchase Price pursuant to Section  2.2.2 . If either Party pays Severance Taxes owed by the other, to the extent such payment is not included as an adjustment to the Purchase Price pursuant to Section  2.2 , upon receipt of evidence of payment the nonpaying Party will reimburse the paying Party promptly for the nonpaying Party’s proportionate share of such taxes.

9.4 Tax and Financial Reporting . If the Parties mutually agree that a filing of Form 8594 is required, the Parties will confer and cooperate in the preparation and filing of their respective forms to reflect a consistent reporting of the agreed upon allocation of the purchase price (as determined for tax purposes) among each Conveyed Interest. Seller and Buyer agree to furnish to each other any and all information, documents or other assistance reasonably requested by the other Party to comply with tax and financial reporting requirements and audits.

Page 55
