3.5    Preliminary Settlement Statement. Not less than five Business Days prior to Closing, Seller shall prepare and submit to Buyer for review a draft settlement statement (the “Preliminary Settlement Statement”) that shall set forth the Adjusted Purchase Price, reflecting each adjustment made in accordance with this Agreement as of the date of preparation of such Preliminary Settlement Statement and the calculation of the adjustments used to determine such amount, together with the designation of Seller’s accounts for the wire transfers of funds as set

forth in Section 3.1 and Section 12.3(d). Within two Business Days after receipt of the Preliminary Settlement Statement, Buyer will deliver to Seller a written report containing all changes, with explanation therefor, that Buyer proposes to be made to the Preliminary Settlement Statement, if any. The Parties shall in good faith attempt to agree on the Preliminary Settlement Statement as soon as possible after Seller’s receipt of Buyer’s written report. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Purchase Price at Closing; provided that if the Parties do not agree on an adjustment set forth in the Preliminary Settlement Statement prior to the Closing, the amount of such adjustment set forth in the Preliminary Settlement Statement as presented by Seller will be used to adjust the Purchase Price at Closing.

3.6    Final Settlement Statement.

(a)    On or before 240 days after the Closing, Seller shall deliver to Buyer a final settlement statement (the “Final Settlement Statement”) prepared by Seller based on actual income and expenses during the Interim Period and which takes into account all final adjustments made to the Purchase Price and shows the resulting final Adjusted Purchase Price (the “Final Price”). The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within 30 days after receipt of the Final Settlement Statement, Buyer will deliver to Seller a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Any changes not so specified in the Dispute Notice shall be deemed waived and Seller’s determinations with respect to all such elements of the Final Settlement Statement that are not addressed specifically in the Dispute Notice shall prevail. If Buyer fails to timely deliver a Dispute Notice to Seller containing changes Buyer proposes to be made to the Final Settlement Statement, the Final Settlement Statement as delivered by Seller will be deemed to be correct and mutually agreed upon by the Parties, and will be final and binding on the Parties and not subject to further audit or arbitration. If the Final Price set forth in the Final Settlement Statement is mutually agreed upon by Seller and Buyer, the Final Settlement Statement and the Final Price shall be final and binding on the Parties, subject to the provisions of Section 2.3(b). Any difference in the Adjusted Purchase Price as paid at Closing pursuant to the Preliminary Settlement Statement and the Final Price shall be paid by the owing Party to the owed Party within 10 days after final determination of such owed amounts in accordance herewith. All amounts paid pursuant to this Section 3.6 shall be delivered in United States currency by wire transfer of immediately available funds to the account specified in writing by the relevant Party.

(b)    Subject to matters for which a Party has an indemnity obligation pursuant to Article XIII, the Final Settlement Statement shall be the final accounting for any and all Operating Expenses, and there shall be no adjustment for, or obligation to pay, any Operating Expenses between the Parties following the Final Settlement Statement.

3.7    Disputes. If Seller and Buyer are unable to resolve the matters addressed in the Dispute Notice (if any), each of Buyer and Seller shall within 14 Business Days after the delivery of such Dispute Notice, summarize its position with regard to such dispute in a written document of 20 pages or less and submit such summaries to the Houston office of Deloitte & Touche LLP, or such other Person as the Parties may mutually select (the “Accounting

Arbitrator”), together with the Dispute Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall render a decision choosing either Seller’s position or Buyer’s position with respect to each matter addressed in any Dispute Notice, based on the materials submitted to the Accounting Arbitrator as described above. Any decision rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on Seller and Buyer and will be enforceable against the Parties in any court of competent jurisdiction. The costs of the Accounting Arbitrator shall be borne pro rata between the Parties with each Party being responsible for the Accounting Arbitrator’s costs to the extent the Accounting Arbitrator has not selected such Party’s position on an aggregate dollar basis with respect to all amounts submitted for resolution by the Accounting Arbitrator.

(a)    On or prior to July 9, 2014, Buyer shall deliver to Seller an updated version of Exhibit B, solely for the purpose of adding the allocation of the Purchase Price among Wells and Well Locations to be set forth under the column titled “Allocated Value” in Exhibit B (the “Allocated Values”); provided that in allocating the Purchase Price among Wells and Well Locations, Buyer shall act reasonably. Buyer and Seller agree that such allocation is reasonable and shall not take positions inconsistent therewith, including in notices to holders of Preferential Purchase Rights. Seller, however, makes no representations or warranties as to the accuracy of such values. Disputes under this Section 3.8 shall be resolved under the procedures described in Section 3.7 hereof.

(b)     For purposes of Income Taxes, Asset Taxes, and other Taxes, Buyer and Seller shall use commercially reasonable efforts to agree to an allocation schedule within 90 days following the Closing Date. Such allocation schedule shall be reasonably consistent with the Allocated Values, as adjusted pursuant to this Agreement. Buyer and Seller shall report the purchase and sale of the Conveyed Interests consistently with any such agreed allocation schedule unless otherwise required by applicable Law.

3.9    Allocation for Imbalances at Closing. If, prior to Closing, either Party discovers an error in the Imbalances set forth in Schedule 7.11, then the Purchase Price shall be further adjusted at Closing pursuant to Sections 3.3(a)(vi), 3.3(a)(vii), 3.3(b)(vii) or 3.3(b)(viii), as applicable, and Schedule 7.11 will be deemed amended immediately prior to Closing to reflect the Imbalances for which the Purchase Price is so adjusted.

4.1    Access.

(a)    From and after the Execution Date and up to and including the Defect Claim Date (or earlier termination of this Agreement pursuant to the terms herein) but subject to the other provisions of this Section 4.1 and obtaining of any required consents of Third Parties, including Third Party operators of the Properties (with respect to which consents Seller shall not be obligated to expend any monies), Seller shall afford to Buyer and its authorized

Buyer hereby fully waives and releases any and all Liabilities against all of the Seller Indemnified Parties for any injury, death, loss or damage to any of Buyer’s Representatives or their property in connection with Buyer’s due diligence activities, EVEN IF SUCH LIABILITIES ARISE OUT OF OR RESULT FROM, IN WHOLE OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OF, OR THE VIOLATION OF LAW BY, A MEMBER OF THE SELLER INDEMNIFIED PARTIES, EXCEPTING ONLY LIABILITIES ACTUALLY RESULTING FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF A MEMBER OF THE SELLER INDEMNIFIED PARTIES.

(e)    Buyer agrees to promptly provide Seller, but in no event less than five days after receipt or creation thereof by Buyer or any of Buyer’s Representatives (including Buyer’s environmental consulting or engineering firm), copies of all final reports prepared by Buyer and/or any of Buyer’s Representatives, which contain data collected or generated from Buyer’s and/or any of Buyer’s Representatives’ due diligence with respect to the Conveyed Interests, including all environmental and title reports. Seller shall not be deemed by its receipt of said documents or otherwise to have made any representation or warranty, express, implied or statutory, as to the condition of the Conveyed Interests or to the accuracy of said documents or the information contained therein.

(f)    Upon completion of Buyer’s due diligence, Buyer shall at its sole cost and expense and without any cost or expense to Seller or any of its Affiliates (i) repair all damage done to any Conveyed Interests in connection with Buyer’s and/or any of Buyer’s Representatives’ due diligence (including due diligence conducted by Buyer’s environmental consulting or engineering firm), (ii) restore the Conveyed Interests to the approximate same condition as, or better condition than, they were prior to commencement of any such due diligence, and (iii) remove all equipment, tools or other property brought onto the Conveyed Interests in connection with such due diligence.

Upon request by Seller, Buyer shall provide evidence of such insurance to Seller prior to entering the Conveyed Interests.

4.2    Confidentiality. Buyer acknowledges that, pursuant to its right of access to the Records or the Conveyed Interests, Buyer and/or Buyer’s Representatives (including Buyer’s environmental consulting or engineering firm) will become privy to confidential and other information of Seller and/or Seller’s Affiliates and Buyer shall ensure that such confidential information (a) shall not be used for any purpose other than in connection with the transactions contemplated by this Agreement and (b) shall be held confidential by Buyer and Buyer’s Representatives (including Buyer’s environmental consulting or engineering firm) in accordance with the terms of the Confidentiality Agreement. If the Closing should occur, the foregoing confidentiality restriction on Buyer, including the Confidentiality Agreement, shall terminate as of the Closing Date (except as to (i) such portion of the Conveyed Interests that are not conveyed to Buyer pursuant to the provisions of this Agreement, (ii) the Excluded Assets, and (iii) information related to Seller, Seller’s Affiliates, or to any assets other than the Conveyed Interests).

Conveyed Interests, and Buyer hereby acknowledges and agrees that Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Conveyed Interests (a) before Closing, shall be as set forth in Section 5.3 and (b) from and after Closing, shall be pursuant to the contractual special warranty of title set forth in the Assignments.

5.2    Special Warranty. The Assignments delivered at Closing will contain a special warranty of title with regard to the Conveyed Interests whereby Seller shall warrant Defensible Title to the Conveyed Interests unto Buyer against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller, but not otherwise, subject, however, to the Permitted Encumbrances. The Mineral Deed delivered at Closing will contain a special warranty of title with regard to the Conveyed Interests specified therein whereby DEPCO shall warrant Defensible Title to such Conveyed Interests unto Buyer against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under DEPCO, but not otherwise, subject, however, to the Permitted Encumbrances.

5.3    Notice of Title Defects; Defect Adjustments.

(a)    Title Defect Notices. On or before the Defect Claim Date, Buyer must deliver claim notices to Seller meeting the requirements of this Section 5.3(a) (collectively, the “Title Defect Notices” and, individually, a “Title Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Section 5.3(a). For all purposes of this Agreement and notwithstanding anything herein to the contrary, Buyer shall be deemed to have waived, and Seller shall have no liability for, any Title Defect which Buyer fails to assert as a Title Defect by a properly delivered Title Defect Notice received by Seller on or before the Defect Claim Date; provided, however, that, for purposes of Seller’s special warranty of title set forth in the Assignments, such waiver shall not apply to any matter that, prior to the Defect Claim Date, is neither reflected of record in the applicable counties or in the applicable state or federal records nor discovered by any of Buyer’s or any of its Affiliates’ employees, title attorneys, landmen or other title examiners while conducting Buyer’s due diligence with respect to the Conveyed Interests. To be effective, each Title Defect Notice shall be in writing, and shall include (i) a description of the alleged Title Defect and the Conveyed Interest (including the legal description of such Conveyed Interest and the Leases applicable to such Conveyed Interest), or portion thereof (including by the currently producing formation or Target Formation as applicable), affected by such alleged Title Defect (each a “Title Defect Property”), (ii) the Allocated Value of each Title Defect Property, (iii) supporting documents reasonably necessary for Seller to verify the existence of the alleged Title Defect, (iv) Buyer’s preferred manner of curing such Title Defect and Buyer’s proposed documentation for such cure and (v) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by such alleged Title Defect and the computations upon which Buyer’s belief is based. To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use reasonable efforts to give Seller, on or before the end of each calendar week prior to the Defect Claim Date, written notice of all alleged Title Defects (as well as any claims that would be claims under the special warranty set forth in the Assignments) discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Defect Claim Date. Buyer shall also, promptly upon discovery, furnish Seller with written notice of any Title Benefit which is discovered by any of Buyer’s or any of its Affiliates’ employees, title

attorneys, landmen or other title examiners while conducting Buyer’s due diligence with respect to the Conveyed Interests prior to the Defect Claim Date.

(b)    Title Benefit Notices. Seller shall have the right, but not the obligation, to deliver to Buyer on or before the Defect Claim Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (1) a description of the alleged Title Benefit and the Conveyed Interest, or portion thereof, affected by such alleged Title Benefit (each a “Title Benefit Property”), and (2) the amount by which Seller reasonably believes the Allocated Value of such Title Benefit Property is increased by such alleged Title Benefit, and the computations upon which Seller’s belief is based. Other than any Title Benefits referred to in the Assignments and any Title Benefits which Buyer is required to report to Seller pursuant to Section 5.3(a), Seller shall be deemed to have waived any Title Benefit which Seller fails to assert as a Title Benefit by a Title Benefit Notice delivered to Buyer on or before the Defect Claim Date.

(c)    Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure any properly asserted Title Defects at any time prior to 180 days after the Closing Date (the “Cure Period”). During the period of time from Closing to the expiration of the Cure Period, Buyer agrees to afford Seller and its officers, employees and other authorized representatives reasonable access, during normal business hours, to the Conveyed Interests and all Records in Buyer’s or any of its Affiliates’ possession in order to facilitate Seller’s attempt to cure any such Title Defects. No reduction shall be made to the Purchase Price with respect to any Title Defect for which Seller has provided notice to Buyer prior to or on the Closing Date that Seller intends to attempt to cure the Title Defect during the Cure Period. An election by Seller to attempt to cure a Title Defect shall be without prejudice to its rights under Section 5.3(j) and shall not constitute an admission against interest or a waiver of Seller’s right to dispute the existence, nature or value of, or cost to cure, the alleged Title Defect.

(d)    Remedies for Title Defects. Subject to Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto, and subject to the rights of the Parties pursuant to Section 14.1(e), in the event that any Title Defect timely asserted by Buyer in accordance with Section 5.3(a) is not waived in writing by Buyer or cured during the Cure Period, Seller shall, at its sole option but subject to Buyer’s agreement in the case of the remedy described in Section 5.3(d)(iii), elect to:

(i)    subject to the Individual Title Defect Threshold and the Aggregate Deductible, reduce the Purchase Price or the Final Price, as applicable, by the Title Defect Amount determined pursuant to Section 5.3(g) or Section 5.3(j);

(ii)    retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Conveyed Interests, or if the Title Defect Property has been assigned to Buyer, have Buyer reassign to Seller, with special warranty of title against claims by, through or under Buyer, but not otherwise, the Title Defect Property that is subject to such Title Defect, together with all associated Conveyed Interests, and, concurrently therewith, the Purchase Price or the Final Price, as applicable, shall be reduced by an amount equal to the Allocated Value of such Title Defect Property and such associated Conveyed Interests;

(iii)    if and only if Buyer agrees to this remedy in its sole discretion, indemnify Buyer against all Liability (up to the Allocated Value of the applicable Title Defect Property) resulting from such Title Defect with respect to such Title Defect Property pursuant to an indemnity agreement prepared by Seller in a form and substance reasonably acceptable to Buyer (a “Title Indemnity Agreement”); or

(iv)    if applicable, terminate this Agreement pursuant to Section 14.1(e).

(e)    Remedies for Title Benefits. With respect to each Title Benefit Property reported under Section 5.3(b), the Purchase Price shall be increased by an amount (the “Title Benefit Amount”) equal to the increase in the Allocated Value for such Title Benefit Property caused by such Title Benefit, as determined pursuant to Section 5.3(h) or Section 5.3(j).

(f)    Exclusive Remedy. Except for Buyer’s rights under Seller’s special warranty of title in the Assignments delivered at Closing and Buyer’s right to terminate this Agreement pursuant to Section 14.1(e), Section 5.3(d) shall be the exclusive right and remedy of Buyer with respect to Seller’s failure to have Defensible Title with respect to any Well, Well Location, or Lease or any other title matter with respect to any Conveyed Interest, and Buyer hereby waives any and all other rights or remedies with respect thereto.

(g)    Title Defect Amount. The amount by which the Allocated Value of a Title Defect Property is reduced as a result of the existence of a Title Defect shall be the “Title Defect Amount” for such Title Defect Property and shall be determined in accordance with the following terms and conditions (without duplication):

(i)    if Buyer and Seller agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(ii)    if the Title Defect is an Encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii)    if the Title Defect represents a discrepancy between (A) Seller’s Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest set forth for such Title Defect Property in Exhibit B, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest set forth for such Title Defect Property in Exhibit B;

(iv)    if the Title Defect represents an increase of (A) Seller’s Working Interest for any Title Defect Property over (B) the Working Interest set forth for such Title Defect Property in Exhibit B, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Working Interest increase and the denominator of which is the Work Interest set forth for such Title Defect Property in Exhibit B;

(v)    if the Title Defect represents an obligation or Encumbrance upon or other defect in title to the Title Defect Property of a type not described above, then the Title

Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property 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 Title Defect Property, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the lesser of (A) the reasonable cost and expense of curing such Title Defect and (B) the Allocated Value of the Title Defect Property;

(vi)    the Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder; and

(vii)    notwithstanding anything to the contrary in this Article V, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of such Title Defect Property.

(h)    Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions (without duplication):

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

(ii)    if the Title Benefit represents a discrepancy between (A) Seller’s Net Revenue Interest for any Title Benefit Property and (B) the Net Revenue Interest set forth for such Title Benefit Property in Exhibit B, then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property multiplied by a fraction, the numerator of which is the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest set forth for such Title Benefit Property in Exhibit B;

(iii)    if the Title Benefit represents a decrease of (A) Seller’s Working Interest for any Title Benefit Property over (B) the Working Interest set forth for such Title Benefit Property in Exhibit B, then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property multiplied by a fraction, the numerator of which is the Working Interest decrease and the denominator of which is the Work Interest set forth for such Title Benefit Property in Exhibit B; and

(iv)    if the Title Benefit is of a type not described above, then the Title Benefit Amounts shall be determined by taking into account the Allocated Value of the Title Benefit Property, the portion of such Title Benefit Property affected by such Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of such Title Benefit Property, the values placed upon the Title Benefit by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation.

(i)    Title Defect Threshold and Deductible. Notwithstanding anything herein to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller hereunder for any individual Title Defect for which the Title Defect

Amount does not exceed $100,000 (“Individual Title Defect Threshold”); and (ii) in no event shall there be any adjustment to the Purchase Price or other remedies provided by Seller hereunder for any Title Defect for which the Title Defect Amount exceeds the Individual Title Defect Threshold unless (A) the amount of the sum of (1) the aggregate Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold (but excluding any Title Defect Amounts attributable to Title Defects cured by Seller or Title Defect Properties retained by or reassigned to Seller, as applicable, pursuant to Section 5.3(d)(ii)), plus (2) the aggregate Remediation Amounts of all Environmental Defects that exceed the Individual Environmental Threshold (but excluding any Remediation Amounts attributable to Conveyed Interests subject to Environmental Defects that are retained by Seller pursuant to Section 6.1(b)(ii) and any Environmental Defects cured by Seller), exceeds (B) the Aggregate Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other applicable remedies available hereunder, but only to the extent that the amount by which the aggregate amount of such Title Defect Amounts and Remediation Amounts exceeds the Aggregate Deductible. For the avoidance of doubt, if Seller elects to retain any Title Defect Property or to have Buyer reassign any Title Defect Property pursuant to Section 5.3(d)(ii), the Title Defect Amount relating to the Conveyed Interest attributable to such Title Defect Property will not be counted towards the Aggregate Deductible and will not be considered for purposes of Section 10.4 or Section 11.4.

(j)    Title Dispute Resolution. Seller and Buyer shall attempt to agree on matters regarding (i) all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts, and (ii) the adequacy of any curative materials provided by Seller to cure any alleged Title Defect (collectively “Title Disputes”) prior to Closing. If Seller and Buyer are unable to agree by Closing (or by the Title Dispute Date if Seller elects to attempt to cure an alleged Title Defect after Closing), the Title Disputes shall be exclusively and finally resolved pursuant to this Section 5.3(j). There shall be a single arbitrator, who shall be a title attorney with at least 10 years’ experience in oil and gas titles involving properties in any of the regional areas in which the Title Defect Properties or Title Benefit Properties, as applicable, are located, in each case as selected by the mutual agreement of Buyer and Seller within 15 days after Closing or the Title Dispute Date, as applicable (the “Title Arbitrator”). If the Parties do not mutually agree upon the Title Arbitrator in accordance with this Section 5.3(j), the Houston office of the AAA shall appoint the Title Arbitrator under such conditions as the AAA in its sole discretion deems necessary or advisable. The place of arbitration shall be Houston, and the arbitration shall be conducted in accordance with the AAA Rules, to the extent such rules do not conflict with the terms of this Section 5.3(j). The Title Arbitrator’s determination shall be made within 30 days after submission of Title Disputes and shall be final and binding upon both Parties, without right of appeal. In making his determination with respect to any Title Dispute, the Title Arbitrator shall be bound by the rules set forth in Section 5.3(g) and Section 5.3(h) and, subject to the foregoing, may consider such other matters as, in the opinion of the Title Arbitrator, are necessary to make a proper determination. The Title Arbitrator, however, may not award Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific Title Disputes submitted by either Party, and the Title Arbitrator may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case to the Title Arbitrator. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Title

Arbitrator. To the extent the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.5 or Section 3.6, then within 10 days after the Title Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Title Dispute, and, subject to Section 5.3(i), (i) Buyer shall pay to Seller the amount, if any, so awarded by the Title Arbitrator to Seller and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer. Nothing herein shall operate to cause Closing to be delayed on account of any arbitration that may be conducted pursuant to this Section 5.3(j), and, to the extent any adjustments are not agreed upon by the Parties as of Closing, the Purchase Price shall not be adjusted therefor at Closing and subsequent adjustments to the Purchase Price, if any, will be made pursuant to Section 3.7 or this Section 5.3(j).

5.4    Casualty or Condemnation Loss.

(a)    Notwithstanding anything herein to the contrary, from and after the Effective Time, if Closing occurs, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the depreciation of Personal Property due to ordinary wear and tear, in each case, with respect to the Conveyed Interests, and Buyer shall not assert such matters as Casualty Losses or Title Defects hereunder.

(b)    If, after the Execution Date but prior to the Closing Date, any portion of the Conveyed Interests is damaged or destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain (each, a “Casualty Loss”), and the Closing thereafter occurs, Seller, at Closing, shall pay to Buyer all sums actually paid to Seller by Third Parties by reason of any Casualty Loss insofar as with respect to the Conveyed Interests and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards, and other rights against Third Parties (excluding any Liabilities, other than insurance claims, of or against any Seller Indemnified Party) arising out of such Casualty Loss insofar as with respect to the Conveyed Interests; provided, however, that Seller shall reserve and retain (and Buyer shall assign to Seller) all right, title, interest and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to Closing in repairing such Casualty Loss and/or pursuing or asserting any such insurance claims or other rights against Third Parties.

5.5    Preferential Purchase Rights and Consents to Assign.

(a)    With respect to each Preferential Purchase Right set forth in Schedule 7.9, not later than 10 days after the Execution Date (and, with respect to each Preferential Purchase Right that is not set forth in Schedule 7.9 but is discovered by either Party after the Execution Date and before the Closing Date, not later than five days after the discovery thereof), Seller shall send to the holder of each such Preferential Purchase Right a notice in material compliance with the contractual provisions applicable to such Preferential Purchase Right.

(i)    If, prior to Closing, any holder of a Preferential Purchase Right notifies Seller that it intends to consummate the purchase of the Conveyed Interest to which its Preferential Purchase Right applies, then the Conveyed Interest subject to such Preferential

Purchase Right shall be excluded from the Conveyed Interests to be assigned to Buyer at Closing (but only to the extent of the portion of such Conveyed Interest affected by the Preferential Purchase Right), and the Purchase Price shall be reduced by the Allocated Value of the Conveyed Interest (or portion thereof) so excluded. Seller shall be entitled to all proceeds paid by any Person exercising a Preferential Purchase Right prior to Closing. If such holder of such Preferential Purchase Right thereafter fails to consummate the purchase of the Conveyed Interest (or portion thereof) covered by such Preferential Purchase Right on or before the end of the period of time for closing such sale but no later than 180 days following the Closing Date, (A) Seller shall so notify Buyer, (B) Buyer shall purchase, on or before 10 days following receipt of such notice, such Conveyed Interest (or portion thereof) that was so excluded from the Conveyed Interests to be assigned to Buyer at Closing, under the terms of this Agreement and for a price equal to the amount by which the Purchase Price was reduced at Closing with respect to such excluded Conveyed Interest (or portion thereof), and (C) Seller shall assign to Buyer the Conveyed Interest (or portion thereof) so excluded at Closing pursuant to an instrument in substantially the same form as the Assignment. If, as of Closing, the time for exercising a Preferential Purchase Right has not expired and such Preferential Purchase Right has not been exercised or waived, then the Conveyed Interest subject to such Preferential Purchase Right shall be included in the Conveyed Interests to be assigned to Buyer at Closing, and Buyer shall be solely responsible for complying with the terms of such Preferential Purchase Right and shall be entitled to the proceeds, if any, associated with the exercise of such Preferential Purchase Right.

(ii)    All Conveyed Interests for which any applicable Preferential Purchase Right has been waived, or as to which the period to exercise the applicable Preferential Purchase Right has expired, in each case, prior to Closing, shall be sold to Buyer at Closing pursuant to the provisions of this Agreement.

(b)    With respect to each Consent set forth in Schedule 7.4, Seller, not later than 10 days after the Execution Date (and, with respect to each Consent that is not set forth in Schedule 7.4 but is discovered by either Party after the Execution Date and before the Closing Date, not later than five days after the discovery thereof), shall send to the holder of each such Consent a notice in material compliance with the contractual provisions applicable to such Consent seeking such holder’s consent to the transactions contemplated hereby.

(i)    If (A) Seller fails to obtain a Consent set forth in Schedule 7.4 (or any Consent that is not set forth in Schedule 7.4 but is discovered by either Party after the Execution Date and before the Closing Date) prior to Closing and the failure to obtain such Consent would cause (1) the assignment of the Conveyed Interests affected thereby to Buyer to be void or (2) the termination of a Lease under the express terms thereof or (B) a Consent requested by Seller is denied in writing, then, in each case, the Conveyed Interest (or portion thereof) affected by such un-obtained Consent shall be excluded from the Conveyed Interests to be assigned to Buyer at Closing, and the Purchase Price shall be reduced by the Allocated Value of such Conveyed Interest (or portion thereof) so excluded. In the event that any such Consent (with respect to a Conveyed Interest excluded pursuant to this Section 5.5(b)(i)) that was not obtained prior to Closing is obtained within 180 days following the Closing Date, then, within 10 Business Days after such Consent is obtained, (x) Buyer shall purchase the Conveyed Interest (or portion thereof) that was so excluded as a result of such previously un-obtained Consent and pay to Seller the amount by which the Purchase Price was reduced at Closing with respect to the

Conveyed Interest (or portion thereof) so excluded and (y) Seller shall assign to Buyer the Conveyed Interest (or portion thereof) so excluded at Closing pursuant to an instrument in substantially the same form as the Assignment.

(ii)    If Seller fails to obtain a Consent set forth in Schedule 7.4 (or any Consent that is not set forth in Schedule 7.4 but is discovered by either Party after the Execution Date and before the Closing Date) prior to Closing and (A) the failure to obtain such Consent would not cause (1) the assignment of the Conveyed Interest (or portion thereof) affected thereby to Buyer to be void or (2) the termination of a Lease under the express terms thereof and (B) such Consent requested by Seller is not denied in writing by the holder thereof, then the Conveyed Interest (or portion thereof) subject to such un-obtained Consent shall nevertheless be assigned by Seller to Buyer at Closing as part of the Conveyed Interests and Buyer shall have no claim against, and Seller shall have no Liability for, the failure to obtain such Consent.

(iii)    Prior to Closing, Seller and Buyer shall use their commercially reasonable efforts to obtain all Consents listed in Schedule 7.4 (and any Consent that is not set forth in Schedule 7.4 but is discovered by either Party after the Execution Date and before the Closing Date); provided, however, that neither Party shall be required to incur any Liability or pay any money in order to obtain any such Consent. Subject to the foregoing, Buyer agrees to provide Seller with any information or documentation that may be reasonably requested by Seller and/or the Third Party holder(s) of such Consents in order to facilitate the process of obtaining such Consents.

6.1    Environmental Defects.

(a)    Assertions of Environmental Defects. Buyer must deliver claim notices to Seller meeting the requirements of this Section 6.1(a) (collectively the “Environmental Defect Notices” and individually an “Environmental Defect Notice”) not later than the Defect Claim Date setting forth any matters which, in Buyer’s reasonable opinion, constitute Environmental Defects and which Buyer intends to assert as Environmental Defects pursuant to this Section 6.1. For all purposes of this Agreement, Buyer shall be deemed to have waived, and Seller shall have no liability for, any Environmental Defect which Buyer fails to assert as an Environmental Defect by a properly delivered Environmental Defect Notice received by Seller on or before the Defect Claim Date, with such liabilities being “Buyer’s Environmental Liabilities.” To be effective, each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter constituting the alleged Environmental Condition (including the applicable Environmental Law violated or implicated thereby) and the Conveyed Interests affected by such alleged Environmental Condition, (ii) the Allocated Value of the Conveyed Interests (or portions thereof) affected by such alleged Environmental Condition, (iii) supporting documents reasonably necessary for Seller to verify the existence of such alleged Environmental Condition, and (iv) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Condition. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the alleged Environmental Condition that gives rise to the

asserted Environmental Defect and identify all assumptions used by Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws. Notwithstanding anything to the contrary in this Article VI, the aggregate Remediation Amounts attributable to the effects of all Environmental Defects upon any single Conveyed Interest shall not exceed the Allocated Value of such Conveyed Interest. Seller shall have the right, but not the obligation, to cure any asserted Environmental Defect on or before the expiration of the Cure Period. No reduction shall be made to the Purchase Price with respect to any asserted Environmental Defect for which Seller has provided notice to Buyer prior to or on the Closing Date that Seller intends to attempt to cure the asserted Environmental Defect during the Cure Period. To give Seller an opportunity to commence reviewing and curing Environmental Defects, Buyer agrees to use reasonable efforts to give Seller, on or before the end of each calendar week prior to the Defect Claim Date, written notice of all alleged Environmental Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Defect Claim Date.

(b)    Remedies for Environmental Defects. Subject to Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, and subject to the rights of the Parties pursuant to Section 14.1(e), in the event that any Environmental Defect timely asserted by Buyer in accordance with Section 6.1(a) is not waived in writing by Buyer or cured prior to Closing, Seller shall, at its sole option but subject to Buyer’s agreement in the case of the remedy described in Section 6.1(b)(iii), elect to:

(i)    Subject to the Individual Environmental Threshold and the Aggregate Deductible, reduce the Purchase Price by the Remediation Amount;

(ii)    retain the entirety of the Conveyed Interest that is subject to such Environmental Defect, together with all associated Conveyed Interests, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Conveyed Interest and such associated Conveyed Interests;

(iii)    if and only if Buyer agrees to this remedy in its sole discretion, to indemnify Buyer against all Liability resulting from such Environmental Defect with respect to the Conveyed Interests pursuant to an indemnity agreement prepared by Seller in a form and substance reasonably acceptable to Buyer (each, an “Environmental Indemnity Agreement”); or

(iv)    if applicable, terminate this Agreement pursuant to Section 14.1(e).

If Seller elects the option set forth in clause (i) above, Buyer shall be deemed to have assumed responsibility for all of the costs and expenses attributable to the Remediation of the Environmental Condition attributable to such Environmental Defect and for all Liabilities with respect thereto and Buyer’s obligations with respect to the foregoing shall be deemed to constitute Assumed Obligations.

(c)    Exclusive Remedy. Except for Buyer’s rights to terminate this Agreement pursuant to Section 14.1(e), the provisions set forth in Section 6.1(b) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect with respect to any Conveyed Interest or other environmental matter.

(d)    Environmental Deductibles. Notwithstanding anything herein to the contrary, (i) in no event shall there be any adjustment to the Purchase Price or other remedies provided by Seller for any individual Environmental Defect for which the Remediation Amount does not exceed $200,000 (the “Individual Environmental Threshold”); and (ii) in no event shall there be any adjustment to the Purchase Price or other remedies provided by Seller for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Threshold unless (A) the amount of the sum of (1) the aggregate Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold (but excluding any Remediation Amounts attributable to any Environmental Defects cured by Seller and Conveyed Interests retained by Seller pursuant to Section 6.1(b)(ii)) plus (2) the aggregate Title Defect Amounts of all Title Defects that exceed the Individual Title Defect Threshold (but excluding any Title Defect Amounts attributable to Title Defects cured by Seller and Title Defect Properties retained by or reassigned to Seller, as applicable, pursuant to Section 5.3(d)(ii)), exceeds (B) the Aggregate Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other applicable remedies available hereunder, but only with respect to the amount by which the aggregate amount of such Remediation Amounts and Title Defect Amounts exceeds the Aggregate Deductible. For the avoidance of doubt, if Seller elects to retain any Conveyed Interest related to any Environmental Defect pursuant to Section 6.1(b)(ii), then (x) the Purchase Price shall be reduced by the Allocated Value of such retained Conveyed Interest and (y) the Remediation Amount for the Environmental Defect relating to such retained Conveyed Interest will not be counted towards the Aggregate Deductible.

(e)    Environmental Dispute Resolution. Seller and Buyer shall attempt to agree on all Environmental Defects and Remediation Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 6.1(e). There shall be a single arbitrator, who shall be an environmental attorney with at least 10 years’ experience in environmental matters involving oil and gas producing properties in any of the regional areas in which the affected Conveyed Interests are located, as selected by the mutual agreement of Buyer and Seller within 15 days after the Closing Date (the “Environmental Arbitrator”). If the Parties do not mutually agree upon the Environmental Arbitrator in accordance with this Section 6.1(e), the Houston office of the AAA shall appoint such Environmental Arbitrator under such conditions as the AAA in its sole discretion deems necessary or advisable. The place of arbitration shall be Houston, and the arbitration shall be conducted in accordance with the AAA Rules, to the extent such rules do not conflict with the terms of this Section 6.1(e). The Environmental Arbitrator’s determination shall be made within 30 days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 6.1 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award Buyer a greater Remediation Amount than the Remediation Amount claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case to the Environmental Arbitrator. Each of Seller and Buyer shall bear

one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.5 or Section 3.6, then within ten 10 days after the Environmental Arbitrator delivers written notice to Buyer and Seller of his award with respect to any Remediation Amount, and, subject to Section 6.1(d), (i) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Arbitrator to Seller and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Environmental Arbitrator to Buyer. Nothing herein shall operate to cause Closing to be delayed on account of any arbitration conducted pursuant to this Section 6.1(e), and, to the extent any adjustments are not agreed upon by the Parties as of Closing, the Purchase Price shall not be adjusted therefor at Closing and subsequent adjustments to the Purchase Price, if any, will be made pursuant to Section 3.7 or this Section 6.1(e).

6.2    NORM, Asbestos, Wastes and Other Substances. Buyer acknowledges that the Conveyed Interests have been used for exploration, development, and production of oil and gas and that there may be petroleum, produced water, wastes, or other substances or materials located in, on or under the Conveyed Interests or associated with the Conveyed Interests. Equipment and sites included in the Conveyed Interests may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The wells, materials, and equipment located on the Conveyed Interests or included in the Conveyed Interests may contain asbestos, NORM and other wastes or Hazardous Substances.

13.7    Indemnification Procedures. All claims for indemnification under Sections 4.1(c), 9.5, 13.2 and 13.3 shall be asserted and resolved as follows:

(a)    For purposes of Section 4.1(c), Section 9.5 and this Article XIII, the term “Indemnifying Party” when used in connection with particular Liabilities shall mean the Party or Parties having an obligation to indemnify another Party and/or other Person(s) with respect to such Liabilities pursuant to Section 4.1(c), Section 9.5 or this Article XIII, and the term “Indemnified Party” when used in connection with particular Liabilities shall mean the Party and/or other Person(s) having the right to be indemnified with respect to such Liabilities by the Indemnifying Party pursuant to Section 4.1(c), Section 9.5 or this Article XIII.

(b)    To make a claim for indemnification under Sections 4.1(c), 9.5, 13.2 or 13.3, an Indemnified Party shall notify the Indemnifying Party in writing of its claim under this Section 13.7, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party 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; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 13.7(b) shall not relieve the Indemnifying Party of its obligations under Sections 4.1(c), 9.5, 13.2 or 13.3 (as applicable) 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 materially 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 inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c)    In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its obligation to defend and indemnify the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such 30-day period, at the expense of the Indemnifying Party, to file any motion, answer 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.

(d)    If the Indemnifying Party admits its obligation to defend and indemnify the Indemnified Party against a Third Party Claim, it shall have the right and obligation to diligently defend and indemnify, at its sole cost and expense, the Indemnified Party against such

Third Party Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, at its own expense, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 13.7(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all Liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e)    If the Indemnifying Party does not admit its obligation or admits its obligation to defend and indemnify the Indemnified Party against a Third Party Claim, but fails to diligently prosecute, indemnify against or settle such Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability 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 defend and indemnify the Indemnified Party against a Third Party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for 10 days following receipt of such notice to i) admit in writing its obligation to indemnify the Indemnified Party from and against the liability and consent to such settlement, ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement, or iii) deny liability. Any failure by the Indemnifying Party to respond to such notice shall be deemed to be an election under subsection (i) above.

(f)    In the case of a claim for indemnification not based upon a Third Party Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to (i) cure the Liabilities complained of, (ii) admit its liability for such Liability or (iii) dispute the claim for such Liabilities. If the Indemnifying Party does not notify the Indemnified Party within such 30-day period that it has cured the Liabilities or that it disputes the claim for such Liabilities, the amount of such Liabilities shall conclusively be deemed a liability of the Indemnifying Party hereunder.

13.8    Survival.

(a)    Except for the Specified Representations, the representations and warranties set forth in Section 7.13 and the special warranty of title included in the Assignments, the representations and warranties of Seller in Article VII and Buyer in Article VIII and the covenants and agreements of the Parties in Section 9.1 and Section 12.4, shall in each case terminate on the date that is nine calendar months from the Closing Date. The Specified Representations shall survive Closing without time limit. The representations and warranties set forth in Section 7.13 shall survive until 30 days after the expiration of the period of time set forth in the statute of limitations. The special warranty of title included in the Assignments shall survive for the period set forth in the Assignments. Subject to the foregoing and as set forth in

Section 13.8(b), the remainder of this Agreement shall survive Closing without time limit. Representations, warranties, covenants and agreements shall be of no further force or effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b)    The indemnities in Sections 13.2(a), 13.2(b), 13.3(a) and 13.3(b) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification. Seller’s indemnities set forth in Section 13.2(c) shall survive the Closing for a period of three years from the Closing Date; provided, however, that (i) Seller’s indemnities set forth in Section 13.2(c) relating to the portions of the Specified Obligations defined in item (i) of Section 13.1(b) shall survive until 30 days after the expiration of the period of time set forth in the statute of limitations regarding same and Seller’s indemnities set forth in Section 13.2(c) relating to the portions of the Specified Obligations defined in item (iv) of Section 13.1(b) shall survive without time limit. Buyer’s indemnity set forth in Sections 4.1(c), 9.5 and 13.3(c) shall survive the Closing without time limit and shall be deemed covenants running with the Conveyed Interests (provided that Buyer and its successors and assigns shall not be released from any of, and shall remain jointly and severally liable to the Seller Indemnified Parties for, the obligations and Liabilities of Buyer under such Sections of this Agreement upon any transfer or assignment of any Conveyed Interest). Notwithstanding the foregoing, there shall be no termination of any bona fide claim asserted pursuant to the indemnities in Sections 13.2(a) and 13.2(b) or Sections 13.3(a) through 13.3(c) prior to the date of termination for such indemnity.

13.9    Non-Compensatory Damages. None of the Buyer Indemnified Parties nor Seller Indemnified Parties shall be entitled to recover from Seller or Buyer, or their respective Affiliates, any indirect, consequential, punitive, exemplary, remote or speculative damages or damages for lost profits of any kind arising under or in connection with this Agreement or the transactions contemplated hereby, except to the extent any such Party suffers such damages to a Third Party, which damages (including costs of defense and reasonable attorneys’ fees incurred in connection with defending against such damages) shall not be excluded by this provision as to recovery hereunder. Subject to the preceding sentence, Buyer, on behalf of each of the Buyer Indemnified Parties, and Seller, on behalf of each of the Seller Indemnified Parties, waive any right to recover punitive, special, indirect, exemplary, or consequential damages, remote or speculative, or damages for lost profits of any kind, arising in connection with or with respect to this Agreement or the transactions contemplated hereby.

13.10    Waiver of Right to Rescission. Seller and Buyer acknowledge that, following Closing, the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated by this Agreement. As the payment of money shall be adequate compensation, following Closing, Buyer and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.

13.11    Insurance. The amount of any Liabilities for which any of the Buyer Indemnified Parties is entitled to indemnification under this Agreement or in connection with or

with respect to the transactions contemplated by this Agreement shall be reduced by any corresponding insurance proceeds from insurance policies carried by Buyer realized or that could reasonably be expected to be realized by Buyer if a claim were properly pursued under the relevant insurance arrangements.

13.12    Disclaimer of Application of Anti-Indemnity Statutes. The Parties acknowledge and agree that the provisions of any anti-indemnity statute relating to oilfield services and associated activities shall not be applicable to this Agreement and/or the transactions contemplated hereby.

14.1    Right of Termination. This Agreement and the transactions contemplated herein may be terminated at any time prior to Closing:

(e)    by Buyer if the condition set forth in Section 10.4 has not been satisfied on or before the Closing Date or by Seller if the condition set forth in Section 11.4 is not satisfied on or before the Closing Date;

provided, however, that neither Party shall be entitled to terminate this Agreement pursuant to Sections 14.1(b) through (d) above if such Party or its Affiliates are, at such time, in material breach of this Agreement.

14.2    Effect of Termination. If the obligation to close the transactions contemplated by this Agreement is terminated pursuant to any provision of Section 14.1 hereof, then, except for the provisions of Article I, Sections 4.1(c) through 4.1(g), 4.2, 4.3, 9.8, 13.9, this Section 14.2, Section 14.3, Article XV (other than Sections 15.2(b), 15.7, and 15.8) and such of the defined terms in Appendix I to give context to the surviving provisions, this Agreement shall forthwith become void and the Parties shall have no liability or obligation hereunder except and to the extent such termination results from the material breach by a Party of any of its covenants or agreements hereunder in which case the other Party shall have the right to seek all remedies available at law or in equity, including specific performance, for such material breach and shall

be entitled to recover court costs and attorneys’ fees in addition to any other relief to which such Party may be entitled.

Either Party may change their contact information for notice by giving written notice to the other Party in the manner provided in this Section 15.6. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.

15.15    Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to either Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

15.16    Removal of Name.

As an example, if an indemnity obligation of Seller under Section 13.2 relates only to Conveyed Interests owned by Devon Uinta, Devon Uinta alone would be responsible for 100% of such indemnity obligation. As another example, if an indemnity obligation of Seller under Section 13.2 relates 70% to Conveyed Interests owned by DEPCO and 30% to Conveyed Interests owned by Devon Uinta, DEPCO would be responsible for 70% of such indemnity obligation and Devon Uinta would be responsible for 30% of such indemnity obligation.

15.19    Like-Kind Exchange. Buyer and Seller agree that either or both of Seller and Buyer may elect to treat the acquisition or sale of the Conveyed Interests as an exchange of like-kind property under Section 1031 of the Code (an “Exchange”), provided that the Closing shall not be delayed by reason of the Exchange. Each Party agrees to use reasonable efforts to cooperate with the other Party in the completion of such an Exchange including an Exchange subject to the procedures outlined in Treasury Regulation § 1.1031(k)-1 and/or Internal Revenue Service Revenue Procedure 2000-37. Each of Seller and Buyer shall have the right at any time prior to Closing to assign all or a part of its rights under this Agreement to a qualified intermediary (as that term is defined in Treasury Regulation § 1.1031(k)-1(g)(4)(iii)) or an exchange accommodation titleholder (as that term is defined in Internal Revenue Service Revenue Procedure 2000-37) to effect an Exchange. In connection with any such Exchange, any

exchange accommodation titleholder shall have taken all steps necessary to own the Conveyed Interests under applicable Law. Each Party acknowledges and agrees that neither an assignment of a Party’s rights under this Agreement nor any other actions taken by a Party or any other Person in connection with the Exchange shall release either Party from, or modify, any of its liabilities and obligations (including indemnity obligations to the other Party) under this Agreement, and neither Party makes any representations as to any particular Tax treatment that may be afforded to any other Party by reason of such assignment or any other actions taken in connection with the Exchange. Either Party electing to treat the acquisition or sale of the Conveyed Interests as an Exchange shall be obligated to pay all additional costs incurred hereunder as a result of the Exchange, and in consideration for the cooperation of the other Party, the Party electing Exchange treatment shall agree to pay all costs associated with the Exchange and to indemnify and hold the other Party, its Affiliates, and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives harmless from and against any and all liabilities and Taxes arising out of, based upon, attributable to or resulting from the Exchange or transactions or actions taken in connection with the Exchange that would not have been incurred by the other Party but for the electing Party’s Exchange election.

15.20    Specific Performance. The Parties agree that if any of the provisions of this Agreement are not performed by a Party in accordance with their specific terms, the other Party shall be entitled to specific performance of the terms hereof, in addition to any other remedy available at law or in equity.

15.21    Non-Recourse. Notwithstanding anything to the contrary herein, except to the extent a named party to this Agreement (and then only to the extent of the specific obligations undertaken by such named party in this Agreement), (a) no past, present or future director, officer, employee, incorporator, member, partner, stockholder, Financing Source, agent, attorney, advisor or representative or Affiliate of any named party to this Agreement, in their respective capacities as such, and (b) no past, present or future director, officer, employee, incorporator, member, partner, stockholder, Financing Source, agent, attorney, advisor or representative or Affiliate of any of the foregoing, in their respective capacities as such, shall have any liability (whether in contract, tort, equity or otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities of any one or more Seller or Buyer under this Agreement (whether for indemnification or otherwise) of or for any claim based on, arising out of, or related to this Agreement or the Debt Financing.
