Section 4.Purchase Price Adjustments.

(a)Upward Adjustments. The Purchase Price shall be increased (without duplication) for: (i) all proceeds (including proceeds held in suspense or escrow and proceeds received after the Effective Time for Hydrocarbons produced and held in storage but not sold as of the Effective Time) actually received by or credited to Assignee that are attributable to the sale of Hydrocarbons produced from the Conveyed Interests prior to the Effective Time and that are not otherwise paid

to Assignor (excluding, for clarity, any proceeds against which Marathon offset any Satisfied Pipeline Costs, regardless of whether Assignor disputes the appropriateness of such offsets), (ii) all Property Expenses paid or borne by Assignor and attributable to the ownership or operation of the Conveyed Interests from and after the Effective Time and not otherwise reimbursed by Assignee, (iii) all Burdens paid or borne by Assignor and attributable to Hydrocarbons produced from the Conveyed Interests after the Effective Time, (iv) all Property Taxes allocated to Assignee under Section 19 that are paid or otherwise economically borne by Assignor, (v) to the extent the Conveyed Interests are under-produced, the volume of such wellhead imbalances as of the Effective Time attributable to the Conveyed Interests, multiplied by $2.50 per MCF, and (vi) to the extent the Conveyed Interests are over-delivered, the volume of any such pipeline or transportation imbalances as of the Effective Time attributable to the Conveyed Interests, multiplied by the monthly price applicable to deliveries to the applicable pipeline during the calendar month of the Closing Date.

(b)Downward Adjustments. The Purchase Price shall be decreased (without duplication) for: (i) all proceeds (including proceeds held in suspense or escrow) actually received by or credited to Assignor that are attributable to the sale of Hydrocarbons produced from the Conveyed Interests on or after the Effective Time, (ii) all Property Expenses attributable to the ownership or operation of the Conveyed Interests prior to the Effective Time which are paid or borne by Assignee but not otherwise reimbursed by Assignor, (iii) all Burdens paid or borne by Assignee and attributable to Hydrocarbons produced from the Conveyed Interests prior to the Effective Time, (iv) the amount of all Property Taxes allocated to Assignor under Section 19 that are paid or otherwise economically borne by Assignee, (v) to the extent the Conveyed Interests are over-produced, the volume of such wellhead imbalances as of the Effective Time attributable to the Conveyed Interests, multiplied by $2.50 per MCF, and (vi) to the extent the Conveyed Interests are under-delivered, the volume of any such pipeline or transportation imbalances as of the Effective Time attributable to the Conveyed Interests, multiplied by the monthly price applicable to deliveries to the applicable pipeline during the calendar month of the Closing Date.

(c)Closing Statement. A preliminary statement (the “Closing Statement”) setting forth the actual figures, or to the extent the actual figures are not available, mutually agreed estimate of each adjustment to the Purchase Price in accordance with Sections 4(a) and (b), and the calculation of such adjustments and the adjusted Purchase Price determined by such calculation, is attached hereto as Appendix III. Additional adjustments necessary to give effect to the provisions of Section 4 and Section 19 of this Agreement will be made pursuant to Section 4(d).

(d)Final Statement. On or before one hundred twenty (120) days after the Closing, Assignee shall prepare (with the reasonable assistance and cooperation of Assignor) and deliver to Assignor a final closing statement setting forth a detailed calculation of all final adjustments to the Purchase Price (the “Final Statement”). Each Party shall provide the other access to such of the Party’s records as may be reasonably necessary to verify the post-Closing adjustments shown on the Closing Statement. If Assignor disputes any items in or the accuracy and completeness of the Final Statement, then as soon as reasonably practicable, but in no event later than fifteen (15) business days after its receipt of the Final Statement, Assignor will deliver to Assignee a written exception report containing any changes Assignor proposes to be made to the Final Statement and the reasons therefor (“Dispute Notice”). If Assignor fails to deliver the Dispute Notice to Assignee

within that period, then the Final Statement as delivered by Assignee will be deemed true and correct, binding upon and not subject to dispute by any Party. If Assignor delivers a timely Dispute Notice, then as soon as reasonably practicable, but in no event later than fifteen (15) business days after Assignee receives Assignor’s Dispute Notice, the Parties will meet and undertake, in good faith, to agree on the final post-Closing adjustments to the Purchase Price. If the Parties fail to agree on the final post-Closing adjustments within sixty (60) days after Assignee’s receipt of the Dispute Notice, then the Parties will submit the dispute to a nationally recognized accounting firm mutually agreed upon by the Parties, which firm has not performed any material work for any of the Parties or their affiliates within the preceding five (5) year period (“Accounting Expert”). The cost of the Accounting Expert shall be paid fifty percent (50%) by each Party. Each Party shall present to the Accounting Expert, with a simultaneous copy to the other Party, a single written statement of its position on the dispute in question, together with a copy of this Agreement, the Closing Statement, the proposed Final Statement, the Dispute Notice and any supporting material that such Party desires to furnish, not later than ten (10) business days after appointment of the Accounting Expert. In making its determination, the Accounting Expert shall be bound by the terms of this Agreement and, without any additional or supplemental submittals by either Party (except as may be specifically requested by the Accounting Expert), may consider such other accounting and financial standards matters as in its opinion are necessary or appropriate to make a proper determination. The Parties shall direct the Accounting Expert to resolve the disputes within thirty (30) days after receipt of the written statements submitted for review and to render a decision in writing based upon such written statements. The Accounting Expert shall act as an expert for the limited purpose of determining the specific Final Statement dispute presented to it, shall be limited to the procedures set forth in this Section 4(d), shall not have the powers of an arbitrator, shall not consider any other disputes or matters, and may not award damages, interest, costs, attorney’s fees, expenses or penalties to any Party. Upon agreement of the Parties to the adjustments to the Final Statement, or upon resolution of such adjustments by the Accounting Expert, as the case may be, the amounts in the Final Statement (as adjusted pursuant to such agreement or resolution by the Accounting Expert) (such amount, the “Final Price”) will be deemed final, conclusive and binding on all of the Parties, without right of appeal, and the aggregate amount due to either Party pursuant to such Final Statement will be paid within five (5) business days after the final determination is made that such payments are due and payable, by wire transfer of immediately available funds pursuant to wire transfer instructions designated in advance by the receiving Party to the paying Party in writing for the account of the receiving Party.

(e)Payments and Reimbursements. Until the first (1^st) anniversary of the Closing Date (including for any items that are the subject of a notice delivered by one Party to the other Party prior to such anniversary), any proceeds, costs, or expenses that would constitute upward or downward adjustments herein but that are not reflected in the Final Statement shall be treated as follows: (a) Assignor will promptly forward, or cause to be forwarded, to Assignee any payments received by or credited to Assignor with respect to proceeds that would constitute downward adjustments but are not reflected in the Final Statement; (b) Assignor will be responsible for costs or expenses that would constitute downward adjustments but that are not reflected in the Final Statement and shall promptly pay, or, if paid or borne by Assignee, promptly reimburse Assignee for such costs or expenses; (c) Assignee will promptly forward, or cause to be forwarded, to Assignor any payments received by or credited to Assignee with respect to proceeds that would constitute upward adjustments but that are not reflected in the Final Statement; and (d) Assignee

will be responsible for costs or expenses that would constitute upward adjustments but that are not reflected in the Final Statement and shall promptly pay, or, if paid or borne by Assignor, promptly reimburse Assignor for such costs or expenses.

All Property Taxes attributable to the ownership or operation of the Conveyed Interests with respect to any taxable period that begins prior to and ends on or after the Effective Time (a “Straddle Period”) shall be apportioned between Assignor and Assignee as of the Effective Time, in the case of Property Taxes described in clause (i) of the definition thereof, based on the number of days in the Straddle Period that occurred before the Effective Time (in the case of Assignor) and on or after the Effective Time (in the case of Assignee), and in the case of Property Taxes described in clause (ii) of the definition thereof, based on (a) actual production, expressed in volume or units, attributable to the days in the Straddle Period that occurred before the Effective Time (in the case of Assignor) and (b) actual production, expressed in volume or units, attributable to the days in the Straddle Period that occur on or after the Effective Time (in the case of Assignee). Each Party shall have the right to all deductions, credits, and refunds pertaining to Property Taxes allocated to such Party under this Section 19.

Section 20.Parent Guaranty. By execution of this Agreement, to the extent that Assignor is obligated to indemnify any Assignee Indemnified Party pursuant to Section 9, Assignor Parent hereby agrees that it guarantees the full, complete, and timely performance and payment when due of, all of the indemnification obligations of Assignor under Section 9 after taking into account the limitations set forth therein applicable to such indemnification obligations (the “Guaranteed Obligations”), to the extent and only to the extent that any claim by an Assignee Indemnified Party with respect to a Guaranteed Obligation is properly asserted on or before the first (1^st) anniversary of the Closing Date and provided that Assignor Parent does not waive its right to dispute that an amount claimed against Assignor Parent pursuant to the foregoing guaranty (“Guaranty”) does not constitute a Guaranteed Obligation; provided, however, that (x) any amounts paid by Assignor on account of the Guaranteed Obligations shall not be owed by Assignor Parent hereunder and (y) in no event shall Assignor Parent’s aggregate Liability under the Guaranty and/or otherwise in respect of the Guaranteed Obligations exceed the Final Price (the

“Cap”). The limitations set forth in this Section 20 shall apply only to the Guaranty and shall not limit any obligations of Assignor hereunder. In connection with Assignor Parent’s performance of its obligations under this Section 20, Assignor Parent shall have the right to exercise any and all rights of Assignor under this Agreement. Notices to Assignor Parent shall be made to the address set forth for Assignor on the signature page to this Agreement. Assignor Parent is executing the Agreement for purposes of this Section 20 only, provided that the provisions of Section 15 through Section 18 and Section 23 through Section 26 shall apply as between Assignor Parent and Assignee with respect to this Guaranty. This Guaranty is an absolute guaranty of payment and not of collection, and a separate action may be brought against Assignor Parent to enforce this Guaranty, without requirement that any Assignee Indemnified Party first exercise its rights against Assignor. Assignor Parent waives diligence, presentment, demand, protest, and notices of any kind in respect of the Guaranteed Obligations and this Guaranty. Assignor is a wholly owned subsidiary of Assignor Parent, and Assignor Parent acknowledges that it is familiar with this Agreement, the Assignment, and other documents delivered in connection herewith and that it will substantially benefit if the transaction contemplated hereby is consummated and performed in accordance with the terms hereof and thereof. This Guaranty shall terminate and Assignor Parent shall not have any further obligations under this Agreement as of the earlier of (1) the first (1st) anniversary of the Closing Date unless a claim by an Assignee Indemnified Party with respect to a Guaranteed Obligation is properly asserted on or before such date and such claim has not been fully satisfied and then only until such claim has been fully satisfied and (2) the time at which Assignor Parent has paid Assignee, in respect of the obligations of Assignor Parent hereunder, an amount equal to the Cap. Assignee hereby expressly agrees that Assignor Parent’s Liability is capped at the Cap and that the Cap is fair and reasonable. Assignee further expressly acknowledges that the Cap is a material inducement for Assignor and Assignor Parent to enter into this Agreement and to provide the Guaranty set forth in this Section 20 and that Assignor Parent is relying on the enforceability of the Cap in providing the Guaranty. In no event shall the Guaranty apply to (i) any entity or Person that is an owner (directly or indirectly) of Assignor Parent or (ii) any other Affiliate (excluding Assignee) of Assignor Parent.

Section 21.Certain Consents. Prior to the Closing Date, Assignor sent to the holder of the consent set forth on Schedule 5(k) (the “Subject Consent”) a notice in compliance with the contractual provisions applicable to such consent seeking such holder’s consent to the transaction contemplated herein. As of the Closing, such holder has not delivered such consent and the time for granting the Subject Consent has not yet expired. Therefore, the Parties agree that (a) at Closing, Assignor’s interests in the Oil and Gas Properties covered by the Subject Consent (the “Subject Assets”) shall not be conveyed to Assignee at Closing but shall still be considered part of the Conveyed Interests in accordance with the provisions of this Section 21, adjustments to the Purchase Price will still be made pursuant to Section 4 with respect to the Subject Assets, and the Purchase Price will not be reduced as a result of such non-conveyance, and (b) after Closing, Assignor and Assignee will use their commercially reasonable efforts (at no out-of-pocket cost or expense to either Party) to obtain promptly the Subject Consent. As between Assignor and Assignee, (i) Assignor shall hold the Subject Assets after Closing as nominee for Assignee, and Assignee shall have full beneficial ownership of, and control over all decisions to be made with respect to, the Subject Assets (including control over elections under operating agreements and incurring any expenses in connection therewith), (ii) Assignee shall pay all Property Expenses and Taxes attributable to the ownership and operation of the Subject Assets from and after the Effective Time, and (iii) Assignor shall pay Assignee any revenues actually received by or credited to

Assignor that are attributable to production from the Subject Assets from and after the Effective Time. At such time as the Subject Consent has been received or deemed received pursuant to the terms of the underlying instrument, (a) Assignor shall so notify Assignee (or, if the Subject Consent is received by Assignee, then Assignee shall so notify Assignor) and (b) within five (5) business days after the receiving Party’s receipt of such notice, Assignor shall assign and convey to Assignee, and Assignee shall accept from Assignor, the Subject Assets pursuant to the terms of this Agreement and an instrument in substantially the same form as the Assignment. If the Subject Consent has not been received or deemed received on or before one hundred and twenty (120) days after the Closing Date, then Assignor shall no longer hold the Subject Assets as nominee for Assignee and, within five (5) business days thereafter, Assignor shall assign and convey to Assignee, and Assignee shall accept from Assignor, the Subject Assets pursuant to the terms of this Agreement and an instrument in substantially the same form as the Assignment. TO THE EXTENT THAT ASSIGNOR HAS MATERIALLY COMPLIED WITH THIS SECTION 21, ASSIGNEE SHALL ASSUME ALL RISK AND SHALL DEFEND AND INDEMNIFY THE ASSIGNOR INDEMNIFIED PARTIES FOR ALL CLAIMS RELATED TO AN ALLEGED FAILURE TO COMPLY WITH SUCH SUBJECT CONSENT, AND SUCH OBLIGATIONS SHALL BE ASSUMED OBLIGATIONS UNDER THIS AGREEMENT.

Section 22.Records. In addition to the obligations set forth under Section 2 above, no later than ten (10) business days following the Closing Date, Assignor shall (a) deliver to Assignee electronic copies of all Records that are maintained in electronic form and (b) make all physical copies of the Records available for pick up by Assignee at their present location(s) (in the format(s) currently maintained by Assignor).

Section 23.Conflicts; No Merger. In the event of a conflict between the terms and provisions of this Agreement and the terms and provisions of any exhibit or schedule hereto, the Assignment, or any other document delivered in connection herewith, the terms and provisions of this Agreement shall govern and control; provided, however, the inclusion in any such exhibit, schedule, or other document of terms and provisions not addressed in this Agreement shall not be deemed a conflict, and all such additional provisions shall be given full force and effect, subject to the provisions of this Section 23. None of the provisions of this Agreement shall be deemed to have merged with the Assignment or any other document executed in connection with this Agreement and, except as otherwise expressly provided herein, the representations, warranties, covenants, agreements, and indemnities contained herein and in the Assignment shall survive the Closing Date without time limit.

Section 24.Legal Fees; Expenses. All fees, costs, and expenses incurred by either Party in negotiating this Agreement or in consummating the transactions contemplated by this Agreement shall be paid by the Person incurring the same, including legal and accounting fees, costs, and expenses. If either Party institutes a Proceeding against the other Party relating to this Agreement or the Assignment, the Party to such Proceeding which does not prevail will reimburse the prevailing Party therein (regardless of whether the prevailing Party is the plaintiff or the defendant in such Proceeding) for the reasonable costs and expenses (including attorney fees) incurred by the prevailing Party related to such Proceeding.

Section 25.Counterparts. This Agreement may be executed and delivered in one or more counterparts, each of which when executed and delivered shall be an original, and all of

which when executed shall constitute one and the same instrument. The exchange of copies of this Agreement and of signature pages by facsimile or by electronic image scan transmission in .pdf shall constitute effective execution and delivery of this Agreement as to the Parties and Assignor Parent and may be used in lieu of the original Agreement for all purposes. Signatures of the Parties and Assignor Parent transmitted by facsimile or electronic image scan transmission in .pdf shall be deemed to be their original signatures for all purposes.

forth in Appendix II to the Purchase Agreement for such Well, except for any decreases required to allow other Working Interest owners to make up wellhead imbalances or pipelines to make up pipeline imbalances, as applicable, and (ii) obligates Assignor to bear not more than the Working Interest as set forth in Appendix II to the Purchase Agreement for such Well, except for any such increases that are accompanied by a proportionate increase in Assignor’s Net Revenue Interest, and (b) as to each Conveyed Interest, is free and clear of any and all Encumbrances created by, through, or under Assignor and/or its Affiliates.

“Eagle Ford Shale Formation” means the stratigraphic equivalent of the formation which is the entire correlative interval from 10,294 feet to 10,590 feet as shown on the log of the EOG Resources, Inc. – Milton Unit, Well No. 1 (API No. 42-255-31608), Section 64, John Randon Survey, A-247, Karnes County, Texas.

“Working Interest” means the percentage of costs and expenses associated with the exploration, drilling, development, operation and abandonment of any Wells required to be borne with respect thereto, without giving effect to any Burdens.
