ARTICLE II
PURCHASE PRICE AND ADJUSTMENTS

2.1 Purchase Price. The base purchase price (the “Base Purchase Price”) will be US$975,000,000.00, paid in cash as hereafter provided.

2.2 Procedure for Determination and Payment of Purchase Price.

(a) No later than the close of business on the third Business Day following execution of this Agreement, Buyer will pay Seller, by wire transfer of immediately available funds to an account designated to Buyer in writing by Seller, a sum of money equal to 5% of the Base Purchase Price, as a deposit (the “Deposit”).

(b) The final amount of money to be paid by Buyer in consideration of the sale and delivery of the Assets to Buyer in accordance with this Agreement will be determined by adding to or subtracting from the Base Purchase Price, as applicable, each adjustment to be made to the Base Purchase Price pursuant to Sections 2.3(a) and 2.3(b) (the Base Purchase Price, as so adjusted, will be referred to herein as the “Purchase Price”).

(c) At the Closing, Buyer will pay Seller by wire transfer in immediately available funds to the account previously designated by Seller, the Purchase Price less the Deposit.

2.3 Adjustments to Base Purchase Price.

(a) To determine the Purchase Price (as herein defined), the Base Purchase Price shall be increased by the following amounts:

(i) the amount of all ad valorem, production, severance, property or similar Taxes paid by Seller and relating to the Assets for periods from and after the Effective Time, calculated in a similar fashion as set forth in Section 2.3(b)(i);

6

(ii) the aggregate amount of any and all operating costs paid by Seller that relate to the Assets for periods from and after the Effective Time (excluding amounts for which the Base Purchase Price is increased pursuant to Section 2.3(a)(i) above), including, but not limited to, lease operating expenses, transportation and marketing expenses, lease payments, severance and production Taxes;

(iii) the aggregate amount of any and all capital expenditures actually made by Seller or on Seller’s behalf in accordance with the terms of this Agreement and that relate to the Assets for periods from and after the Effective Time;

(iv) the sum of $350,000.00 per month (prorated for parts of months) between the Effective Time and the Closing Date, as Seller’s overhead;

(v) the aggregate amount of money equal to the value of all liquid Hydrocarbons above the load line in tanks on the Leases or in connection with the Assets, as measured and recorded by Seller in the ordinary course of business on November 1, 2011, at a price per barrel of oil or condensate of $90.00;

(vi) The value of Imbalances due to Seller from third parties, at $3.59 per MMBtu of gas;

(vii) the cost of the audit to be performed pursuant to Section 5.13, unless Buyer otherwise pays such costs; and

(viii) any other amount agreed upon by the parties in writing.

(b) To determine the Purchase Price, the Base Purchase Price shall be decreased by the following amounts:

(i) the amount of all of Seller’s unpaid ad valorem, production, severance, property or similar Taxes relating to the Assets, to the extent that such unpaid Taxes relate to periods of time before the Effective Time (to the extent that any such amount has not been finally determined by Closing or any other date of determination, such amount will be estimated based upon the amount paid for the previous year for the same Asset or Assets). Such Taxes with respect to a period which the Effective Time splits shall be prorated based on the number of days in such period which fall on each side of the Effective Time; provided however, to the extent that such Taxes are computed based on the production from the Assets, such Taxes shall be prorated between the parties based on the period in which the production which is the basis for such calculation occurs, in the same manner as the parties are entitled to receive (or be credited with) such production pursuant to the terms hereof;

(ii) amounts equal to all revenues (net of royalty, overriding royalty payments and similar such payments) collected or earned by Seller that are attributable to the sale of Hydrocarbons from the Assets (but not taking into account any xxxxxx) and relating to periods of time from and after the Effective Time;

7

(iii) the aggregate of the Title Defect Amounts (as defined in the Title Defect Mechanism) with respect to those Title Defects that are asserted during the Title Examination Period and agreed to by Seller as an adjustment to the Base Purchase Price;

(iv) the aggregate of the Environmental Defect Amounts with respect to Environmental Defects asserted prior to the Defect Deadline and agreed to by Seller as an adjustment to the Base Purchase Price;

(v) the aggregate of the Allocated Values attributable to Xxxxx affected by Required Consents if the applicable consent is not received prior to Closing;

(vi) the amount of the Suspense Funds as of the Closing Date; and

(vii) the value of Imbalances payable by Seller, at $3.59 per MMBtu of gas;

(viii) any other amount agreed upon by the parties in writing.

2.4 Preliminary Settlement Statement.

(a)  Seller shall prepare and deliver to Buyer, not later than 3:00 p.m. Central Standard Time on the date that is 5 Business Days prior to the Closing Date, a statement (the “Preliminary Settlement Statement”) setting forth Seller’s good faith estimate of each adjustment to be made in accordance with Sections 2.3(a) and (b). Buyer may dispute in good faith Seller’s estimate of the amount of such adjustments by delivering to Seller written notice of any such disputes no later than 5:00 p.m., Central Standard Time on the date that is 3 Business Days prior to the Closing Date. Buyer and Seller shall use commercially reasonable efforts to resolve any such dispute prior to Closing; provided, that any and all amounts so disputed or other adjustments claimed by Seller and not resolved by mutual agreement of Buyer and Seller prior to Closing shall be resolved in accordance with Section 2.5 and Closing shall occur with payment of the Purchase Price without adjustment due to the disputes; provided, however Title Defects shall be addressed as set forth in Sections 2.3(b)(iii) and the Title Defect Mechanism.

(b)  After the Closing, the Purchase Price shall be subject to further adjustment pursuant to Section 2.5 and neither Seller’s delivery of an estimate of adjustments pursuant to this Section 2.4, the delivery of a dispute notice by Buyer pursuant to this Section 2.4, nor the failure to deliver any such dispute notice shall bar any such further adjustments pursuant to Section 2.5.

2.5 Final Settlement Statement.

(a) On or before the 120th day after the Closing, Seller shall prepare and deliver to Buyer in accordance with this Agreement, a statement (the “Final Settlement Statement”) setting forth Seller’s calculation of the final adjustments to be made to the Base Purchase Price pursuant to Section 2.1.

8

(b) Within 20 days after receipt of the Final Settlement Statement, Buyer may deliver to Seller a written report containing any changes that Buyer proposes be made to the Final Settlement Statement and the reasons for those changes. The parties shall attempt to agree to the amounts due pursuant to such adjustments, including any disputed amounts, no later than 30 days after Buyer’s receipt of the Final Settlement Statement.

(c) If Seller and Buyer are unable to agree upon the Final Settlement Statement by the 45th day after Buyer’s receipt of same, the Parties will refer the Final Settlement Statement and any necessary supporting information to KPMG LLP (or, if such firm is unable or unwilling to act, such other nationally recognized independent public accounting firm as shall be agreed upon by Buyer and Seller in writing) (the “Referral Firm”). The Referral Firm will be directed to review Seller’s Final Settlement Statement and the records relating to the Assets and determine the final adjustments, other than adjustments for Title Defects which shall be determined in accordance with the Title Defect Mechanism. With respect to any matters under this Agreement to be resolved by the Referral Firm, neither the Referral Firm nor any person employed by the Referral Firm will interpret the provisions of this Agreement unless otherwise agreed by Seller and Buyer. With respect to any matters for which interpretation of this Agreement is required pursuant to settlement of matters under this Section 2.5, and for which Buyer and Seller cannot agree on such interpretation, such matter shall be submitted to arbitration as provided in Article X and the Referral Firm shall decide all other matters specified in this Section 2.5. The decision of the Referral Firm shall be binding on Buyer and Seller, and the fees and expenses of the Referral Firm shall be borne one-half each by Buyer and Seller. The Referral Firm shall deliver its final calculation of the Purchase Price in writing to Buyer and Seller as soon as practicable, and the parties shall pay and receive the final adjustment amount, no later than the 5th Business Day following the owing party’s receipt from the Referral Firm of the final Purchase Price determination.

(d) The date that is the later of: (i) the 30th day following Buyer’s receipt of the Final Settlement Statement; or (ii) the date on which the last of all disputed adjustments, if there are any, is settled, will be the “Final Settlement Date.” No later than five Business Days after the Final Settlement Date, the party owing the greater amount in accordance with the approved Final Settlement Statement must pay the other party the net difference, by wire transfer of immediately available funds. After the Final Settlement Date, there will be no further adjustments pursuant to Sections 2.2, 2.3, 2.4 and 2.5 unless the amount to be adjusted exceeds $50,000.00.

(e) The parties will, and will cause their representatives to, cooperate and assist in the preparation of the Final Settlement Statement and the conduct of the reviews and audits referred to in this Section 2.5, including but not limited to making available books, records and personnel as reasonably required.

2.6 Allocation of Purchase Price.

(a) Schedule 2.6(a) sets forth Seller’s Working Interest and Net Revenue Interest in the Xxxxxxx Shale Formation in each Well. Schedule 2.6(a) also sets forth Seller’s proposed Working Interest and Net Revenue Interest in each potential well on Seller’s leasehold that Seller has identified as a viable additional drillsite on Seller’s leashold or lands pooled or unitized therewith (a “Valued Location”).

(b) Buyer has prepared Schedule 2.6(b), setting forth the monetary amount, for each Well and Valued Location, allocated by Buyer to determine the Base Purchase Price (the “Allocated Values”). “Allocated Value” means the value allocated to any individual portion of the Assets, as set forth on Schedule 2.6(b).

(c) In addition to allocating value as provided on Schedule 2.6(b), Buyer must separately allocate value to the parcel of real property described on Schedule 1.1(v) as the Willow Park tract.

(d) Seller and Buyer agree that they will further allocate the Purchase Price among the Assets for Tax purposes in a manner consistent with Section 1060 of the Code and the regulations thereunder based upon the fair market value of the Assets. Buyer shall deliver such purchase price allocation to Seller, for Seller’s review and comment, within 60 days after Closing. Seller and Buyer shall work in good faith to agree on the amounts and reporting of the purchase price allocation in accordance with Section 1060 of the Code and the regulations thereunder; provided, however, that if Seller and Buyer cannot agree on the amounts and reporting of the purchase price allocation, each of Seller and Buyer shall be free to report the purchase price allocation in a manner that each party reasonably believes is the most consistent with the requirements of Section 1060 of the Code and the regulations thereunder. If Seller and Buyer are able to agree on the amounts and reporting of the purchase price allocation, then to the extent that the Purchase Price is adjusted pursuant to Section 2.5, Seller and Buyer shall work in good faith to agree on the appropriate revisions to the purchase price allocation. If Seller and Buyer agree on the purchase price allocation, Seller and Buyer agree to file all information reports and Tax Returns (including IRS Form 8594 and any amended Tax Returns or claims for refund) in a manner consistent with the purchase price allocation agreed upon under this Section 2.6; provided, however, that:

(i) Buyer’s cost for the Assets may differ from the total amount allocated thereunder to reflect Buyer’s capitalized transaction costs not included in the amount allocated, and

(ii) Seller’s amount realized on the sale of the Assets may differ from the total amount so allocated to reflect Seller’s transaction costs that reduce the amount realized.

5.4 Consents and Preferential Rights.

(a) Immediately following the execution of this Agreement, Seller will notify the holders of the consent rights and preferential rights set forth on Schedule 3.2. Seller will exercise commercially reasonable efforts to satisfy all of such requirements prior to the Closing.

16

(b) Schedule 5.4 sets forth a list of Leases and Property Agreements requiring the consent of third parties to assign that, if not obtained by Closing, would: (i) invalidate the conveyance of the Assets, (ii) result in the termination of the affected agreement, or (iii) result in the material breach of the affected agreement (collectively, the “Required Consents”); provided, however, that consents and approvals that are customarily obtained post Closing (such as federal and state approvals of assignments), and other consents that do not specifically invalidate the conveyance if not obtained are not “Required Consents.” Seller shall use commercially reasonable efforts to obtain all Required Consents and to give notices required in connection with preferential purchase rights prior to Closing.

Buyer shall reasonably cooperate with Seller in obtaining any Required Consent.

(d) Subject to the terms of the Assignment, all other agreements set forth on Schedule 3.2 will be assigned to Buyer at Closing and it will be the responsibility of Buyer to obtain the required consents after Closing.

(e) If any preferential right to purchase any portion of the Assets is exercised prior to the Closing Date, or if the time frame for the exercise of such preferential purchase right has not expired and Seller has not received notice of an intent not to exercise or waiver of the preferential purchase right, then that portion of the Assets affected by such preferential purchase right shall be excluded from the Assets at Closing and the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of such affected Assets. If a portion of the Assets is excluded from the Assets conveyed at Closing because the time for exercising a preferential right to purchase has not run, but the time for exercising expires without exercise before the end of the Cure Period, Seller will convey the affected portion of the Assets to Buyer, and Buyer will pay Seller the Allocated Value of the affected portion of the Assets, subject to any applicable adjustments pursuant to Section 2.3

(f) If a third party exercises its preferential right to purchase, but fails to consummate the transaction prior to the Closing, Seller shall retain the affected Assets at Closing and the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of such affected Assets.

17

(g) If a third party exercises its preferential right to purchase, but does not consummate the transaction within the time frame specified in the preferential purchase right (provided that the reason therefore is not Seller’s default), Seller agrees to convey the affected Asset to Buyer as soon as possible after the expiration of the time for consummation of the transaction by the holder of the preferential right, such conveyance to be effective as of the Effective Time, and Buyer agrees to pay Seller the Allocated Value of the affected Asset.

(h) If a preferential purchase right is not discovered prior to Closing, and the affected Asset is conveyed to Buyer at Closing, and the preferential purchase right is exercised after Closing, Buyer agrees to convey such affected Asset to the party exercising such right on the same terms and conditions under which Seller conveyed such Asset to Buyer (with the purchase price being the Allocated Value for the affected Asset) and retain all amounts paid by the party exercising such preferential right to purchase. In the event of such exercise, Buyer shall prepare, execute and deliver a form of conveyance of such Asset to such exercising party, such conveyance to be in form and substance as provided in this Agreement.

(i) The remedies set forth in this Section 5.4 are the exclusive remedies for the preferential purchase rights and consents (including Required Consents)

At the Closing, Seller will execute and deliver to Buyer a mutually agreeable Transition Services Agreement (the “Transition Services Agreement”), providing for (i) the administration of the Operated Xxxxx or Assets (as applicable) for the period of time after the Closing necessary to account for at least the production month of December, 2011, (ii) the transportation and marketing of Buyer’s gas until March 31, 2012, pursuant to Section 5.11, (iii) assistance with telemetry issues during Buyer’s process of obtaining and implementing all necessary licensing for required radio frequencies and equipment, and (iv) such other matters that are agreed to therein.

5.6 Environmental Matter Notification.

(a) Beginning on the date of this Agreement and ending December 13, 2011 (such date, the “Defect Deadline”), Seller shall afford to Buyer and its representatives reasonable access during normal business hours, at its sole risk and expense, to conduct such environmental investigation of the Assets as Buyer may in its sole discretion choose to conduct in order to determine whether Environmental Defects (as defined below) exist (“Environmental Investigations”). Buyer will employ a third party environmental consultant selected by Buyer and approved by Seller (which approval shall not be unreasonably withheld) (the “Environmental Consultant”) to determine the existence of any Environmental Defects and the Environmental Defect Amount associated therewith.

(b) Seller agrees to reasonably cooperate with Buyer’s Environmental Investigations, but any and all such Environmental Investigations shall be performed at Buyer’s sole risk and expense. Buyer’s Environmental Investigations shall be conducted in accordance with Laws and shall not interfere with the business of Seller.

If Buyer or its agents prepares an environmental assessment of any portion of the Assets at any time prior to Closing, Buyer agrees to keep such assessment confidential (except as required to be disclosed pursuant to any applicable law or Governmental Authority) and to furnish copies thereof to Seller.

18

(c) If Buyer discovers, prior to the Defect Deadline, any Environmental Defect affecting any of the Assets, Buyer may notify Seller of such alleged Environmental Defect. To be effective, such notice (“Environmental Defect Notice”) must:

(d) “Environmental Defect” means a condition in, on or under the Asset (including without limitation, with respect to air, land, soil, surface and subsurface strata, surface water and ground water) that (X) is attributable to the period of time prior to the Effective Time, and (Y) causes an Asset to be in material violation of an Environmental Law, and the Environmental Defect Amount exceeds $50,000 with respect to any individual portion of the Assets and per condition, net to Seller’s interest; provided, however, that any Environmental Defect affecting multiple portions of the Assets from a single occurrence shall be treated as a single Environmental Defect and subject to only one $50,000 threshold.

(e) Notwithstanding that Buyer delivers timely and effective Environmental Defect Notices to Seller, there will be no adjustment to the Base Purchase Price with respect to Environmental Defects and no obligation of Seller to attempt to cure any Environmental Defect or retain liability for any Environmental Defect unless the sum of all Environmental Defect Amounts attributable to Environmental Defects identified by Buyer in timely-delivered and effective Environmental Notices exceeds 1.5% of the Base Purchase Price (the “Environmental Defect Basket”), in which event Seller will provide Buyer with a Seller Response to the Environmental Defects that are in excess of the Environmental Defect Basket. Buyer may not claim an adjustment to the Base Purchase Price for Environmental Defects affecting a portion of the Assets if the applicable portion of the Assets has been excluded from the Assets conveyed at Closing pursuant to any other provision of this Agreement.

19

(f) No later than three Business Days after the Defect Deadline, Seller shall notify Buyer in writing that it elects either (items (i) through (iv), below, “Seller’s Response”):

(iii) with the consent of Buyer, to retain the liability associated with the alleged Environmental Defect and indemnify Buyer against the same as a Retained Liability; or

(iv) to dispute the Environmental Defect or the Environmental Defect Amount as set forth in paragraph (g), below.

(g) If Seller disputes any Environmental Defects or the Environmental Defect Amounts with respect thereto, then, if practicable under the circumstances, representatives of Buyer and Seller knowledgeable in environmental matters shall meet no later than three Business Days following the date of Seller’s response and either (i) mutually agree to reject the particular Environmental Defect or (ii) agree on the validity of such Environmental Defect and the Environmental Defect Amount with respect thereto. If the Parties cannot agree on either options (i) or (ii) in the preceding sentence, or the Parties cannot meet (and do not otherwise agree to resolve the matter), the applicable Environmental Defects and the Environmental Defect Amounts in dispute shall be resolved through an arbitration proceeding conducted in the manner provided for Title Defects in the Title Defect Mechanism, except that the arbitrator must be a person familiar by training and experience with Environmental Laws and their application in the oil and gas industry; provided, however, if the Parties are unable to agree on a resolution associated with any Environmental Defects raised by Buyer, the Parties shall proceed to Closing without adjustment of the Base Purchase Price for the disputed Environmental Defects and the matters will be resolved after Closing through the aforementioned arbitration procedures.

As soon after Closing as is reasonably practical for Buyer to obtain and have in place all necessary equipment and/or licenses necessary to replace the MCLM Licenses and otherwise have the ability to electronically monitor well activity (but no earlier than the termination of Seller’s provision of accounting services under the Transition Services Agreement), Seller will assign to Buyer, and Buyer will accept from Seller, without warranty of any kind, assignment of such portions of the radio telemetry system as Seller is able to assign (other than the MCLM Licenses, which will be retained by Seller), at no cost to Buyer other than the costs, if any, incurred by Seller to make the assignment. Notwithstanding the foregoing, Seller will not assign to Buyer any software associated with the radio telemetry system unless Buyer agrees to pay all costs imposed by the licensor of such software.

(c) Buyer and Seller furnish to each other such necessary information and reasonable assistance as the other may reasonably request in connection with the preparation, filing and prosecution of the request for consent from the FCC.

(c) The parties agree to cooperate with each other as reasonably required after the Closing Date in connection with audits and other proceedings with respect to any Taxes relating to the Assets.

(d) Notwithstanding any other provision of this Agreement, the covenants and obligations set forth in this Section 7.1 shall survive until, and any claim for indemnification with respect thereto must be made prior to, the expiration of the applicable statute of limitations with respect to the underlying Tax claim (including any valid extensions).

(e) Notwithstanding anything contained in this Agreement, each party will be solely responsible for its own income and franchise Taxes arising out of or attributable to the Assets and the transactions contemplated by this Agreement.

(f) Seller reserves the right, at or prior to Closing, to assign its rights under this Agreement, solely with respect to all or a portion of the Purchase Price, and/or that portion of the Assets associated therewith, to a Qualified Intermediary (as that term is defined in Section 1.1031(k)-1(g)(4) of the Treasury Regulations) (the “QI”) to accomplish this transaction, in whole or in part, as a like-kind exchange (“Like-Kind Exchange”) under Section 1031 of the Code. Buyer hereby (i) consents to Seller’s assignment described above, and (ii) if such an assignment is made, provided Buyer received timely notice thereof, Buyer agrees to pay all or a portion of the Purchase Price, when paid, into a qualified trust or escrow account as directed in writing by such Seller.

26

(g) Buyer reserves the right, at or prior to Closing, to assign its rights under this Agreement with respect to all or a portion of the Assets to Buyer’s QI or to Buyer’s Qualified Exchange Accommodation Titleholder (as that term is defined in Revenue Procedure 2000-37) (the “QEAT”) in connection with effecting a Like-Kind Exchange.

(h) Seller and Buyer acknowledge and agree that a whole or partial assignment of this Agreement to a QI or a QEAT shall not release either Seller or Buyer from, or expand, any of their respective liabilities and obligations to each other under this Agreement.

7.2 Casualty. If any Asset shall be materially damaged or destroyed by fire or other casualty before the Closing, either party may, at its option, and upon written notice prior to Closing to the other party elect to exclude such Asset from this Agreement. In the event that the Asset to be excluded pursuant to this Section 7.2 is the entirety of a Well or Lease, the Base Purchase Price shall be reduced by the Allocated Value of the portion of the Assets to be excluded. In the event that the Asset sought to be excluded is less than the entirety of a Well or Lease, the Base Purchase Price shall be reduced by a mutually agreed upon amount but not more than the Allocated Value of the entire Asset. If neither party elects to delete such Asset from this Agreement as aforesaid, Seller shall pay the deductible due under any insurance policy or policies insuring the same and deliver to Buyer, at the Closing, any insurance proceeds actually received by it by reason of such casualty, and assign to Buyer all of its right, title and interest in any claim under any applicable insurance policies in respect of such casualty.

7.3 Books and Records.

(a) No later than seven Business Days days after the Closing Date, Seller will deliver to Seller, at Buyer’s expense, any of the Books and Records not delivered to Buyer at Closing.

(b) Buyer will be entitled to the originals of the Books and Records, other than those books and records identified as Tax records, the originals of which will be retained by Seller. Buyer will preserve the Books and Records for a period of six years following the Closing and will allow Seller (or its representatives, consultants and advisors) reasonable access to such records at all reasonable times for a purpose reasonably related to (a) Seller’s ownership of the Assets or (b) the performance by Seller of its obligations, and the enforcement by it of its rights, hereunder. If Buyer desires to dispose of any such records prior to the expiration of the six-year period referenced above, Buyer shall provide notice of same to Seller, and Seller shall have a period of 10 days to deliver written notice to Buyer that Seller elects to have such records delivered to it (at Seller’s expense). If Seller fails to deliver such notice within the 10-day period referenced above, Buyer shall the right to dispose of the subject records.

27

7.4 Service Marks. Buyer will have no right to use the name “Encana Oil & Gas (USA) Inc.”, or any derivative thereof, from and after Closing. All signage bearing such names must be changed within 30 days of the termination of the Transition Services Agreement.

7.5 Surety Bonds. Buyer shall release or cause to be released all of Seller’s surety bonds no later than one month following the Closing Date.

7.6 Other Party’s Funds. After the Closing, to the extent either Seller or Buyer receives any funds to which the other party is entitled by reason of its accrual before, or after, as applicable, the Effective Time, and the settlement of such funds is not otherwise provided for in this Agreement (as an adjustment on the Preliminary Settlement Statement, for example), the party receiving the funds shall promptly deliver such funds to the appropriate party. If either Seller or Buyer pays any cost or expense that is properly borne by the other party pursuant to this Agreement, and the payment is not otherwise adjusted pursuant to the Preliminary Settlement Statement or the Final Settlement Statement, the party responsible for such cost or expense shall reimburse, within 30 days of the date it receives notice of such payment, the party who made the payment.

(i) the breach of a representation or warranty made by Buyer in this Agreement;

(ii) the breach of or default in the performance by Buyer of any covenant, agreement or obligation to be performed by Buyer pursuant to this Agreement or any agreement or instrument executed in connection herewith or pursuant hereto;

(iii) the failure to obtain any consent to assign set forth on Schedule 3.2, other than the Required Consents;

(iv) the Additional Liabilities; and

(v) the Assumed Liabilities.

(b) Within 30 days after receipt by a Seller Indemnified Party of notice of the commencement of an Action or other event giving rise to a Seller Claim with respect to which a Seller Indemnified Party may be entitled to indemnification, the party receiving such notice shall notify (the “Seller Claim Notice”) Buyer in accordance with Section 11.5, in writing of the commencement of such Action or the assertion of such Seller Claim. Buyer shall have the option, and shall notify each indemnified party in writing within 10 Business Days after the date of the Seller Claim of its election, either: (i) to participate (at its own expense) in the defense of the Action or Seller Claim (in which case the defense of such Action or Seller Claim shall be controlled by the Seller Indemnified Party) or (ii) to take charge of and control defense of such Action or Seller Claim (at its own expense). If Buyer fails to notify the Seller Indemnified Party of its election within the applicable response period, then Buyer shall be deemed to have elected not to control the defense of such Action or Seller Claim. If Buyer elects to control the defense of any Action or Seller Claim, each Seller Indemnified Party shall have the right to employ separate counsel and participate in the defense of any such Action or Seller Claim.

(b) Seller’s maximum liability for Losses under Section 8.2 and Buyer’s maximum liability for Losses under Section 8.3 shall be, in each case, 50% of the Purchase Price (the “Maximum Indemnity Amount”).

(c) In order to be effective, an Indemnification Claim must be made prior to the end of the Survival Period in writing to the party against whom it is sought to be enforced. Any such Indemnification Claim for which notice has been given prior to the end of the Survival Period may be prosecuted to conclusion notwithstanding the subsequent expiration of such period.

(d) Title Defects and Environmental Defects are not subject to the limitations set forth in this Section 8.4, but only to the separate limitations applicable to such defects as set forth in Exhibit A and Section 5.6, respectively.

(e) Notwithstanding the foregoing limitations on Seller’s liability, Seller retains all liabilities and obligations associated with the Excluded Assets and the matters set forth on Schedule 8.4.

31

(iii) all Title Defects and Environmental Defects identified by Buyer prior to the Defect Deadline but for which the Base Purchase Price is adjusted pursuant to Section 2.3, even if such matters would also constitute a breach of a representation or warranty of Seller set forth in Article III.

(d) Any matter discovered by Buyer that would be a breach of a representation or warranty of Seller set forth in Article III, but that meets the definition of a Title Defect or Environmental Defect and such matter is not identified by Buyer in a timely-delivered notice to Seller prior to the Defect Deadline, or such matter is identified by Buyer but the matter is not addressed because the applicable defect is part of the basket of defects that is not in excess of the Title Threshold or the Environmental Basket, as applicable, or would be a Title Defect or Environmental Defect but does not meet the definition of such as used herein or is a matter for which the Base Purchase Price is adjusted pursuant to Section 2.3, will be deemed to be waived by Buyer for purposes of the conditions to the Closing set forth in Section 6.2(a).

EXHIBIT A

PROCEDURE FOR CLAIMING TITLE DEFECTS AND ADJUSTING THE BASE PURCHASE PRICE

1.  Title Procedure. From the date this Agreement is executed until 5:00 pm on the Defect Deadline (the “Title Examination Period”), Buyer may make written claims in accordance with this Exhibit A with respect to any Title Defect claimed by Buyer.

2. Notice of Asserted Title Defects. From time to time prior to the expiration of the Title Examination Period, as soon as reasonably practic able following Buyer’s identification of Title Defects with respect to the Leases, Buyer will furnish to Seller written notices specifying in detail each matter which, in Buyer’s opinion, constitutes a Title Defect to a Well or Valued Location and which Buyer wishes to assert as a Title Defect, together with the value allocated to each such asserted Title Defect in accordance with this Title Defect Mechanism (the “Title Defect Amount”) as estimated by Buyer (each such notice being called a “Title Defect Notice”). The Title Defect Notice shall include all documents in support of Buyer’s assertion of a Title Defect.

3. Cure of Title Defects.

(a) If Seller elects to cure a Title Defect set forth in a Title Defect Notice, then Seller may attempt to cure such Title Defect during the Cure Period. As used in this Agreement, “Cure Period” means that period of time from 5:00 p.m. on the date Seller receives the Title Defect Notice, until 5:00 p.m. on the date that is 90 days after the Closing Date. On or before expiration of the Cure Period, Seller may give Buyer written evidence of any curative actions which in Seller’s reasonable determination cure or reduce the Title Defect Amount of any Title Defect asserted by Buyer, including an explanation in reasonable detail of any claimed reduction in the Title Defect Amount.

(b) Leases affected by Title Defects, if the Title Defects have been cured to Buyer’s reasonable satisfaction, will be referred to as “Cured Leases.”

4. Notice in Response to Buyer’s Notice. No later than the day that is three Business Days following the Defect Deadline, Seller shall give written notice to Buyer as to each asserted Title Defect (“Response Notice”), stating:

(a) that it admits the existence of the Title Defect and accepts Buyer’s estimate of the Title Defect Amount, in which event, the Title Defect Amount will be deducted from the Base Purchase Price in accordance with Section 2.3(b) of the Agreement;

(b) that it disputes the existence of the Title Defect or disagrees with the Title Defect Amount estimated by Buyer for such Title Defect, in which event, if such dispute is not resolved prior to Closing, the parties will proceed with Closing without adjustment to the Base Purchase Price and the dispute as to the Title Defect or Title Defect Amount will be handled in accordance with the procedures established in this Title Defect Mechanism; or

(c) that it admits the existence of the Title Defect and Buyer’s estimate of the Title Defect Amount, but intends to cure the asserted Title Defect, in which event Buyer’s asserted Title Defect Value will be deducted from the Base Purchase Price, and:

(i) the portion of the Assets affected by the Title Defect will not be conveyed to Buyer at Closing;

(ii) Seller will have until the end of the Cure Period to attempt to cure, to Buyer’s reasonable satisfaction;

(1) there will be a second Closing, on the Final Settlement Date. At the second Closing, Buyer will pay Seller for all portions of the Assets affected by Title Defects which have been cured to Buyer’s reasonable satisfaction by Seller during the Cure Period, and Seller will assign all such Assets to Buyer using the form of Assignment attached to the Agreement; and

(2) any portions of the Assets affected by Title Defects, which Title Defects have not been cured by Seller as of the end of the Cure Period, will be treated for all purposes as if they were Excluded Assets.

5. Other Matters in Seller’s Response Notice. If Seller disagrees with Buyer’s assertion of the existence of a Title Defect or the Title Defect Amount with respect thereto, Seller’s Response Notice shall also specify in reasonable detail Seller’s grounds for such disagreement, the Title Defect Amount estimated by Seller therefor, or both, as the case may be. If not resolved, either Seller or Buyer may require that any unresolved dispute with respect to the existence of a Title Defect or the Title Defect Amount therefor be submitted to arbitration as provided in Section 8 of this Exhibit A.

6. Release. Except with respect to any claims arising under the limited warranty of title contained in the Assignment, Buyer shall not make any claims, and hereby fully and finally releases Seller from any liability, obligations or damages with respect to such claims, for Title Defects to the extent Buyer does not properly provide a Title Defect Notice for any such Title Defect prior to the end of the Title Examination Period.

7. Method of Determining Title Defect Amounts. Without limiting Seller’s right to dispute the existence of a Title Defect, the value of each Title Defect (the “Title Defect Amount”) for each asserted Title Defect shall be determined as follows:

(a) If the Title Defect results from a Lien or similar encumbrance, other than a Permitted Encumbrance, the Title Defect Amount will be the amount of money required to remove the Lien or similar encumbrance.

(b) If the Title Defect relates to failure of title to the entirety of a Lease, the Title Defect Amount shall be the sum of the Allocated Values of all Xxxxx and Valued Locations associated with the applicable Lease and Seller shall have the Cure Period to cure such Title Defect. If the applicable Lease is a part of a pooled unit, the Title Defect Amount will be determined by multiplying the sum of the Allocated Values of all Xxxxx and Valued Locations affected by the failure of the applicable Lease by a fraction representing the proportion that the applicable Lease bears to the entirety of the pooled unit.

(c) If the Title Defect would result in Seller’s Net Revenue Interest in a Well or Valued Location being less than the interest shown for the relevant Well or Valued Location on Schedule 2.6(b) and Seller’s Working Interest in such well or Lease would not be proportionately reduced, the Title Defect Amount will be an amount equal to the product of the Allocated Value for the relevant Well or Valued Location, multiplied by the percentage reduction in such Net Revenue Interest as a result of such Title Defect.

(d) If the Title Defect results from any matter not described in paragraphs (a), (b) or (c) above, then the Title Defect Amount shall be a portion of the Allocated Value for affected Well or Valued Location, said portion to be equal to the difference between the value of Seller’s title to the applicable Lease, Well or Valued Location without such Title Defect and with such Title Defect (assuming the value without such Title Defect to be the Allocated Value specified for the applicable Well(s) and Valued Location(s)) and Buyer and the Seller agree to negotiate in good faith to determine such Title Defect Amount.

(e) If a Title Defect is not currently effective or does not affect Seller’s title to a Lease, Well or Valued Location throughout the entire useful life of such Lease, Well or Valued Location, such fact shall be taken into account in determining the Title Defect Amount.

(f) If any Title Defect is reasonably susceptible of being cured at a cost less than the Title Defect Amount determined in subsections (a) through (e), the Title Defect Amount shall be the actual cost and expense of curing such Title Defect.

8. Arbitration.

(a) If Buyer or Seller elects to submit any dispute to arbitration as specifically provided in this Exhibit A, then such party shall notify the other party in writing. Within 15 days, Seller and Buyer agree to jointly select an arbitrator. The arbitrator shall be an experienced oil and gas attorney, familiar by training and experience with U.S. oil and gas legal and business matters including titles and oil and gas transactions. This person shall be the sole arbitrator (the “Arbitrator”) to hear and decide all existing disputes regarding asserted Title Defects and Title Defect Amounts. The Arbitrator chosen shall be impartial and independent of the parties. If Seller and Buyer are unable to agree on the Arbitrator within the fifteen-day period, upon request by either party, the Referral Firm shall promptly select an Arbitrator with the qualifications set forth in this paragraph.

(b) Any arbitration hearing, if one is desired by the Arbitrator, shall be held in Dallas, Texas, or such other location as may be acceptable to both parties and the Arbitrator. The Arbitrator may elect to conduct the proceeding by written submissions from the Seller and Buyer with exhibits, including interrogatories, supplemented with appearances by Buyer and Seller as the Arbitrator may desire. The arbitration proceeding, subject only to the terms hereof, shall be conducted informally and expeditiously and in such a manner as to result in a good faith resolution as soon as reasonably possible under the circumstances. The decision of the Arbitrator with respect to such remaining disputed matters shall be reduced to writing and binding on the parties. Judgment upon the award(s) rendered by the Arbitrator may be entered and execution had in any court of competent jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement. Seller and Buyer, respectively, shall bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the Arbitrator shall be borne one-half by Seller and one-half by Buyer.

(c) The arbitration shall commence as soon as possible after the Arbitrator is selected in accordance with the provisions of this Exhibit A. In fulfilling his or her duties with respect to determining the amount of a Title Defect Amount, the Arbitrator may consider such matters as, in the opinion of the Arbitrator, are necessary or helpful to make a proper valuation; however, the Arbitrator shall be bound by those factors set forth in Section 8 of this Exhibit A. Furthermore, the Arbitrator may consult with and engage disinterested third parties to advise the Arbitrator including, without limitation, geologists, geophysicists, petroleum engineers, title and oil and gas lawyers, accountants and consultants, and the fees and expenses of such third parties shall be considered to be charges and expenses of the Arbitrator. The sole remedy in any arbitration award shall be resolution of alleged Title Defects and Title Defect Amounts which shall then be applied as provided in this Exhibit A and the Arbitrator shall not award any other remedy, including, without limitation, equitable relief, actual damages, consequential, exemplary or punitive damages, attorneys’ fees or interest reflecting the time value of money.

(d) Any replacement Arbitrator, should one become necessary, shall be selected in accordance with the procedure provided above for the initial selection of an Arbitrator.

(e) As to any determination of amounts owing under the terms of this Exhibit A, no lawsuit based on such claimed amounts owing shall be instituted by either Buyer or Seller, other than to compel arbitration proceedings or enforce the award of the Arbitrator.

(f) All privileges under state and federal law, including attorney-client and work-product privileges, shall be preserved and protected to the same extent that such privileges would be protected in a federal or state court proceeding applying state or federal law, as the case may be.

9. Title Defect Remedies. Seller’s sole responsibility and Buyer’s sole and exclusive remedy for the reduction in value of Seller’s title to a Lease, Well or Valued Location resulting from the existence of a Title Defect shall be as provided in this Exhibit A and Seller shall not be liable for any Losses in respect of Title Defects and Title Defect Amounts, except to the extent provided under this Exhibit A; provided, however, such limitations shall not apply to any breach of the limited warranty of title contained in the Assignment.

10. Limitations of Title Defect Amount. Notwithstanding the foregoing:

(i) No matter that would otherwise constitute a Title Defect will be considered as a Title Defect for purposes of this Agreement unless the Title Defect Amount with respect to such matter exceeds $20,000; and

(ii) there shall be no adjustment to the Base Purchase Price in accordance with this Exhibit A unless and until the Title Defect Amounts exceed 1.5% of the Base Purchase Price (the “Title Threshold”) in the aggregate, in which event the Base Purchase Price shall be adjusted for all Title Defect Amounts above the Title Threshold.

11. Capitalized Terms. Capitalized terms used herein, if not defined herein, will have the meaning given to such term in the Agreement or the Schedule of Definitions.
