Contribution Agreement, dated May 7, 2012

This Contribution Agreement (this “Agreement”), dated as of May 7, 2012 (the “Effective Date”), is by and between Gulfport Energy Corporation, a Delaware corporation (“Contributor”), and Diamondback Energy, Inc., a Delaware corporation (“Diamondback”). Contributor and Diamondback are hereinafter sometimes referred to individually as a “Party” and together as the “Parties”.

A. Contributor owns certain oil, gas and mineral interests in the Permian Basin in West Texas and related assets and contracts (the “Permian Assets”).

B. Contributor desires to contribute the Permian Assets to Diamondback for shares of common stock, par value $0.01 per share, of Diamondback (the “Common Stock”) and other consideration upon the terms and conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the premises, the respective representations, warranties, covenants and agreements contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the Parties agree as follows:

1.1 Contribution of Permian Assets. At the Closing and subject to the terms and conditions contained in this Agreement, Contributor shall contribute, transfer, assign, convey and deliver to Diamondback (or a wholly-owned Subsidiary of Diamondback as directed by Diamondback), and Diamondback (or such Subsidiary) shall acquire and accept, all of Contributor’s right, title and interest held in the Permian Assets. The Parties shall work together to prepare a mutually agreeable schedule of the Permian Assets as soon as practicable after the Effective Date.

1.2 Retained and Assumed Obligations. Upon the Closing, Diamondback shall assume and agree to fulfill, perform, pay and discharge all duties, obligations, claims and liabilities of every kind and character with respect to the Permian Assets or ownership or operation thereof attributable to periods after the Closing Date, including without limitation, (a) those incurred in the ordinary course of business or otherwise, (b) ad valorem, property, severance and other similar taxes or assessments based upon or measured by the ownership of the Permian Assets or the production therefrom, and (c) those related to the condition of the Permian Assets, including, without limitation, obligations to properly plug and abandon or re-plug or re-abandon or remove wells, flowlines, gathering lines and other facilities, equipment or other personal property or fixtures comprising part of the Permian Assets, obligations to restore the surface of the Permian Assets, obligations to bring the Permian Assets into compliance with applicable Laws and liabilities related to any of the foregoing, other than duties, obligations and

liabilities of the Contributor arising under a JOA and billed or billable prior to the Closing Date (the “Assumed Obligations”); provided, however, that upon the Closing, the Contributor shall retain all of Contributor’s duties, obligations, claims and liabilities of every kind and character with respect to the Permian Assets or ownership or operation thereof attributable to periods prior to the Closing Date, including without limitation (i) those incurred in the ordinary course of business or otherwise; and (ii) ad valorem, property, severance and other similar taxes or assessments based upon or measured by the ownership of the Permian Assets or the production therefrom except to the extent specified in clause (c) above.

1.3 Consideration. At the Closing, Diamondback shall, in exchange for the transfer of the Permian Assets, issue to Contributor the following (the “Closing Consideration”):

(i) (a) that number of shares of Common Stock such that Contributor holds thirty-five percent (35%), of the number of shares of Common Stock outstanding immediately prior to the closing of the IPO after giving effect to the issuance of shares of Common Stock in connection with the Gulfport Contribution and the Wexford Contribution. The remaining shares of Common Stock outstanding immediately prior to the closing of the IPO and after giving effect to the Wexford Contribution and the Gulfport Contribution will be held by DB Holdings. No fractional shares of Common Stock shall be issued to Contributor pursuant to this Agreement; and

(ii) (b) a promissory note in the principal amount of $63,590,050.00 substantially in the form attached hereto as Exhibit A (the “Promissory Note”).

1.4 Closing Date Adjustment. Following the Closing, the Closing Consideration shall be reduced or increased in accordance with this Section 1.4 by an amount equal to the difference between the Initial Capital Amount and the Final Capital Amount, divided by sixty-five percent (65%), and then multiplied by thirty-five percent (35%) (the “Capital Adjustment Amount”). For purposes of this Agreement, “Final Capital Amount” shall mean Windsor’s (a) total current assets, consisting of cash, trade accounts receivable (net of an appropriate allowance for doubtful accounts), inventory, prepaid expenses, other current assets, and other assets, less (b) total current liabilities, consisting of trade accounts payable, accounts payable to related parties, accrued capital and other expenses, long-term debt and asset retirement obligations, in each case as of the Closing Date determined in accordance with GAAP, consistently applied. As soon as practicable after the Closing, but in no event later than sixty (60) days after Closing, Diamondback will cause to be prepared and delivered to the Contributor the final settlement statement (the “Final Settlement Statement”) setting forth Windsor’s calculation of the Final Capital Amount on the Closing Date, which Final Settlement Statement shall identify with specificity each component thereof and be prepared in a manner consistent with the preparation of the Initial Capital Amount. As soon as practicable after receipt of the Final Settlement Statement but in no event later than thirty (30) days after receipt of such statement and the supporting documentation with respect thereto as may be requested by the Contributor, the Contributor shall deliver to Diamondback a written report containing any changes that the Contributor proposes to make to the Final Settlement Statement. The Contributor’s failure to deliver to Diamondback a written report detailing proposed changes to the Final Settlement Statement by that date shall be deemed an acceptance by the Contributor of the Final Settlement

Statement as submitted by Diamondback. The Parties shall agree with respect to the changes proposed by the Contributor, if any, no later than sixty (60) days after receipt of Diamondback’s proposed Final Settlement Statement. If Diamondback disputes the Contributor’s exceptions, then Diamondback and the Contributor will negotiate in good faith to resolve such dispute. If Diamondback and the Contributor are unable to resolve the dispute within thirty (30) days after the date of the Contributor’s dispute notice, then the dispute shall be submitted to a mutually agreed upon arbitrator (the “Arbitrator”) for resolution and the Arbitrator’s decision shall be final and binding on the Parties and there shall be no right of appeal therefrom. The costs of the Arbitrator shall be paid by Diamondback and the Contributor proportionate to the success of the claims made. No later than five (5) days after reaching such agreement, the Capital Adjustment Amount shall be paid, if positive, by Diamondback to the Contributor, and if negative, by the Contributor to Diamondback by wire transfer in immediately available funds.

(a) The Parties intend for the transactions between them contemplated in this Agreement to qualify as a tax-free exchange under Section 351 of the Code and in accordance therewith, the Parties acknowledge that Contributor and DB Holdings together will own one-hundred percent (100%) of all of the issued and outstanding capital stock of Diamondback immediately following the consummation of the Gulfport Contribution and the Wexford Contribution and immediately prior to the consummation of the IPO.

(b) Contributor and Diamondback hereby agree to the U.S. federal income tax treatment described in this Section 1.5, and neither Contributor nor Diamondback shall maintain a position on their respective U.S. federal income tax returns or otherwise that is inconsistent therewith.

1.6 Unwind. If the Gulfport Contribution is made but the IPO does not close for any reason, the Permian Assets shall be returned to Contributor and Contributor shall return the Closing Consideration and this Agreement shall be null and void.

Diamondback hereby represents and warrants to Contributor as of the Effective Date and as of the Closing Date (except to the extent that any such representation or warranty expressly relates to another date, in which case such representation or warranty shall be as of such date) as follows:

(b) authorize for issuance, issue, sell, deliver or agree or commit to issue, sell or deliver (whether through the issuance or granting of options, warrants, commitments, subscriptions, rights to purchase or otherwise) any stock of any class or any other debt or equity securities or equity equivalents (including any stock options or stock appreciation rights);

4.4 Confidentiality. Each Party will, and will cause each of its respective Affiliates, directors, officers, employees, agents, representatives and similarly situated persons to treat and hold as confidential, and not use or disclose, all of the information possessed by such person concerning the Transactions, the Wexford Contribution, the IPO, Diamondback, its business, the negotiation or existence and terms of this Agreement and the business affairs of Contributor, except for disclosures (i) to the person’s professional advisors, the actions for which the disclosing person will be responsible, (ii) required for such person to perform obligations it may have under this Agreement, or (iii) required by applicable Law or securities exchange regulations.

Diamondback shall promptly provide copies or all written comments received from the Commission, and consult with Contributor with respect to any comments received from the Commission regarding the Transaction, and make available to Contributor upon its request a complete and correct copy of any amendments that are filed with the Commission. At its effective time, the S-1 shall comply as to form in all material respects with the rules and regulations promulgated by the Commission under the Securities Act and shall not contain any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein in light of the circumstances under which they were made not misleading. Diamondback will advise Contributor, after it receives notice thereof, of the time when S-1 has become effective or any supplement or amendment has been filed, or the issuance of any stop order.

(b) Diamondback shall use its commercially reasonable efforts to include the shares of Common Stock of Contributor requested by Contributor to be included in the S-1 as a selling stockholder and such shares of Common Stock shall be included in the underwriting on the same terms and conditions as the shares of Common Stock being offered by Diamondback. If the managing underwriters advise Diamondback that in their good faith judgment the number of shares of Common Stock requested to be included in the S-1 by Contributor and DB Holdings exceeds the number which can be sold in the IPO without materially and adversely affecting the marketability of the IPO, then the S-1 shall include the maximum number of shares that the managing underwriters advise can be sold in the IPO by Contributor and DB Holdings allocated as follows: (i) first, the shares of Common Stock that Diamondback proposes to sell, and (ii) second, to the extent that any other shares of Common Stock may be included without exceeding the limitations recommended by the underwriters as aforesaid, shares of Common Stock to be included in the S-1 by Contributor and DB Holdings will be included on a pro rata basis (or in such other proportion mutually agreed between Contributor and DB Holdings), based on the number shares of Common Stock held by Contributor and DB Holdings.

4.7 HSR Filing.

The Parties will cooperate with each other in connection with the making of all such filings or responses, including providing copies of all such documents to the non-filing or non-responding Party and its advisors prior to filing or responding to allow such other Party reasonable time to review and comment on such filings or responses. The filing fees for all such filings after the Effective Date will be paid by Diamondback. Any other fees or expenses that arise in connection with the making of all such filings or responses with respect to the HSR Act will be paid by the Person that incurs such fees or expenses.

(b) For the avoidance of doubt, such termination of the Terminated Agreements (i) shall not affect the Contributor’s right to receive production revenues attributable to its ownership of the Permian Assets during the period prior to the Closing Date, and (ii) shall not relieve Contributor of (x) any obligation for the payment of money or for indemnity under any Terminated Agreement for the period prior to the Closing Date, or (y) the obligation to convey any oil, gas and mineral lease, working interest, leasehold interest or other oil and gas interest covered by the AMIA acquired by Contributor, an Affiliate of Contributor, or an agent or representative of Contributor or any such Affiliate, or which Contributor, Affiliate or agent or representative had the right to acquire prior to the Closing Date.

Nothing contained in this Section 6.2 shall relieve any party from liability for any breach of this Agreement prior to such termination.

(a) Contributor shall indemnify and hold Diamondback and its Affiliates, and their respective officers, directors, managers, employees, agents, representatives, controlling persons, members, stockholders and similarly situated persons, harmless from

and pay any and all Damages directly or indirectly, resulting from, relating to, arising out of or attributable to (i) any breach of any representation or warranty the Contributor has made in this Agreement; or (ii) any breach, violation or default by Contributor of any covenant, agreement or obligation of Contributor in this Agreement. “Damages” means all losses (including diminution in value), damages and other costs and expenses of any kind or nature whatsoever, whether known or unknown, contingent or vested, matured or unmatured, and whether or not resulting from third-party claims, including costs (including reasonable fees and expenses of attorneys, other professional advisors and expert witnesses and the allocable portion of the relevant person’s internal costs) of investigation, preparation and litigation in connection with any Action or threatened Action.

(b) Diamondback shall indemnify and hold the Contributor and its Affiliates, and their respective officers, directors, managers, employees, agents, representatives, controlling persons, members, stockholders and similarly situated persons, harmless from and pay any and all Damages directly or indirectly, resulting from, relating to, arising out of or attributable to (i) any breach of any representation or warranty Diamondback has made in this Agreement; (ii) any breach, violation or default by Diamondback of any covenant, agreement or obligation of Diamondback in this Agreement; or (iii) the Assumed Obligations.

Failure to notify the Indemnitor will not relieve the Indemnitor of any liability that it may have to the Indemnified Party, except to the extent the defense of such Action is materially and irrevocably prejudiced by the Indemnified Party’s failure to give such notice. An Indemnitor may elect at any time to assume and thereafter conduct the defense of the Indemnification Claim with counsel of the Indemnitor’s choice reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnitor will not approve of the entry of any judgment or enter into any settlement with respect to the Indemnification Claim without the Indemnified Party’s prior written approval (which must not be withheld unreasonably). Until an Indemnitor assumes the defense of the Indemnification Claim, the Indemnified Party may defend against the Indemnification Claim in any manner the Indemnified Party reasonably deems appropriate. If the Indemnified Party gives an Indemnitor notice of an Indemnification Claim and the Indemnitor does not, within ten (10) days after such notice is given, give notice to the Indemnified Party of its election to assume the defense of such Indemnification Claim and thereafter promptly assume such defense, then the Indemnitor will be bound by any judicial determination made with respect to such Indemnification Claim or any compromise or settlement of such Indemnification Claim effected by the Indemnified Party.

(b) A claim for any matter not involving a third party may be asserted by notice to the Party from whom indemnification is sought.

FOR VALUE RECEIVED, the undersigned, Diamondback Energy, Inc., a Delaware corporation (“Maker”), promises to pay to the order of Gulfport Energy Corporation, a Delaware corporation (“Payee”), at 14313 N. May Avenue, Suite 100, Oklahoma City, Oklahoma 73134, or any other place as the Payee or any other holder hereof shall designate in writing to Maker, the principal sum of ($ ) in lawful money of the United States of America, with interest on the principal balance remaining unpaid from time to time (a) from the date of this Note until the Maturity Date at zero percent per annum and (b) at any time after the Maturity Date at the rate equal to the lesser of (i) the maximum rate permitted by applicable law (the “Maximum Rate”), and (ii) ten percent (10%) per annum. Interest shall be computed on a per annum basis of a year of 360 days and for the actual number of days elapsed unless such calculation would result in a rate greater than the Maximum Rate, in which case interest shall be computed on a per annum basis of a year of 365 days.

The principal balance of this Note together with all accrued and unpaid interest shall be due and payable on the earliest to occur of (such date the “Maturity Date”): (a) funding of the IPO; (b) , 2012 [the fifth business day after the date of the note]; and (c) acceleration of the principal balance hereof pursuant to the terms of this Note. As used herein “IPO” shall have the meaning given such term in that certain Contribution Agreement, dated as of , 2012, by and between Maker and Payee, as the same may be amended from time to time (the “Contribution Agreement”).

Maker shall have the right to prepay, at any time and from time to time without premium or penalty, the entire unpaid principal balance of this Note or any portion thereof. All payments under this Note shall be applied first to any accrued and unpaid interest as of such date and second to the outstanding principal balance.

All agreements between Maker and the holder of this Note, whether now existing or hereafter arising and whether written or oral, are expressly limited so that in no contingency or event whatsoever, whether by acceleration of this Note or otherwise, shall the amount paid, or agreed to be paid, to the holder hereof for the use, forbearance or detention of the money to be loaned hereunder or otherwise, exceed the Maximum Rate. If from any circumstances whatsoever fulfillment of any provision of this Note or of any other document evidencing, securing or pertaining to the indebtedness evidenced hereby, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstances the holder of this Note shall ever receive as interest under this Note or any other document evidencing, securing or pertaining to the indebtedness evidenced hereby or otherwise an amount that would exceed the Maximum Rate, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing under this Note or on account of any other indebtedness of Maker to the holder hereof relating to this Note, and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of this Note and such other indebtedness, such excess shall be refunded to Maker. In

determining whether or not the interest paid or payable with respect to any indebtedness of Maker to the holder hereof, under any specific contingency, exceeds the Maximum Rate, Maker and the holder hereof shall, to the maximum extent permitted by applicable law, (a) characterize any nonprincipal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, (c) amortize, prorate, allocate and spread the total amount of interest throughout the full term of such indebtedness so that the actual rate of interest on account of such indebtedness is uniform throughout the term thereof, and/or (d) allocate interest between portions of such indebtedness, to the end that no such portion shall bear interest at a rate greater than that permitted by law.

The entire unpaid principal balance of, and all accrued and unpaid interest on, this Note shall immediately be due and payable upon the occurrence of any of the following: (a) failure by Maker to pay any principal amount when due; (b) commencement of a voluntary case against Maker under Title 11 of the United States Code; or (c) the filing of an answer or other pleading admitting or failing to deny the material allegations of a petition filed against Maker commencing an involuntary case under said Title 11 or failure to timely controvert the material allegations of such petition.

If Payee or any other holder hereof expends any effort in any attempt to enforce payment of all or any part or installment of any sum due the holder hereunder, or if this Note is placed in the hands of any attorney for collection, or if it is collected through any legal proceedings, Maker agrees to pay all collection costs and fees incurred by the holder, including attorneys’ fees.

All notices, requests and other communications under this Note will be effective and deemed given if delivered in accordance with Section 8.4 of the Contribution Agreement.

(g) To the extent assignable, all of the following which pertain or are applicable to the Leases, the Wells and the Disposal Facilities (or any of them) or the oil, condensate, gas, casinghead gas and other liquid or gaseous hydrocarbons (the “Hydrocarbons”) produced from the Lands, the Leases or Wells, including, but not limited to, those described on Exhibit “E”, to wit: (i) all operating agreements and unit agreements; (ii) all agreements for the marketing, gathering, transportation and/or processing of Hydrocarbons, including interests and rights, if any, with respect to any prepayments, take-or-pay, buydown and buyout agreements; (iii) contracts and contractual rights constituting a part of the chain of title to Assignor’s rights or interests in the Leases or by which Assignor’s rights in the Leases were acquired (to the extent any portion of said agreements remain executory), including (where applicable) farmout agreements and the like; (iv) all bottomhole agreements, area of mutual interest agreements, acreage contribution agreements, options, leases of equipment or facilities, joint venture agreements, pooling agreements, and gas balancing agreements; and (v) those other contracts and agreements pertaining to the Leases, the Wells or the Disposal Facilities and which are listed on Exhibit “E” (but not otherwise) (any or all of the foregoing, the “Related Contracts”).

(j) All other rights and interests in, to or under or derived from the Real Property Interests, the lands covered thereby or pooled, unitized or directly used or held for use in connection therewith.

(k) Copies of the data and records relating to the foregoing that have been or will be delivered by Assignor to Assignee (“Documents”) subject to the requirements set forth below.

If originals or copies of the Documents have been provided to Assignee, Assignor shall have access to them at reasonable times and upon reasonable notice during regular business hours for as long as any Lease is in effect after the Effective Time. Assignor may, during this period and at its expense, make copies of the Documents upon reasonable request. Without limiting the generality of the two preceding sentences, for a period as long as any Lease is in effect after the Effective Time, Assignee shall not destroy or give up possession of any original or last remaining copy of the Documents without first offering Assignor the opportunity, at Assignor’s expense, to obtain such original or copy.

If any of the above-described interests are excluded from Section 1 of this Assignment because they are not assignable, then, with respect thereto, Assignor will use its commercially reasonable efforts to obtain a waiver of any restrictions on assignment, and if obtained, such interests will thereupon become a part of the Properties.

Section 2. Limited Title Warranty. Assignor warrants and shall forever defend the title to the Properties unto Assignee against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through, or under Assignor but not otherwise, subject, however, to the Permitted Liens (regardless of whether they are released on or prior to the Effective Time pursuant to the Contribution Agreement) and to any other Liens created, imposed, modified, amended or extended under or pursuant to the Loan Documents which will be released on or prior to the Effective Time pursuant to the Contribution Agreement; it being the intent (without modifying, amending or expanding the scope of the preceding warranty of title) that, as of the Effective Time pursuant to the Contribution Agreement, the Properties will not be encumbered by Liens or other defects in title to which the Properties were not encumbered

as of the time the Properties were originally assigned and conveyed to Assignor, save and except for the Permitted Liens (regardless of whether they are released on or prior to the Effective Time pursuant to the Contribution Agreement) and any other Liens created, imposed, modified, amended or extended under or pursuant to the Loan Documents which will be released on or prior to the Effective Time pursuant to the Contribution Agreement. Assignor further warrants that any conveyance of the Properties at the Effective Time pursuant to this Assignment also conveys, assigns and transfers to Assignor, its successors and assigns, as of the Effective Time, all warranties, claims and causes of action of whatsoever type or character, in contract or in tort, that Assignor now has or may hereafter acquire from its predecessors-in-title to the Properties, with respect to title to the Properties. EXCEPT FOR THE LIMITED WARRANTY EXPRESSED IN THE PRECEDING SENTENCE(S) OF THIS SECTION 2, NO WARRANTY OR REPRESENTATION, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, WITH RESPECT TO ASSIGNOR’S TITLE TO ANY OF THE PROPERTIES IS PROVIDED IN THIS ASSIGNMENT.

Section 3. Disclaimer of Other Warranties. EXCEPT FOR THE LIMITED WARRANTY OF TITLE ABOVE MADE, ASSIGNOR MAKES NO WARRANTY OF ANY TYPE IN THIS ASSIGNMENT, WHETHER EXPRESS, STATUTORY, OR IMPLIED. ASSIGNEE HAS INSPECTED AND HAS SATISFIED ITSELF AS TO THE CONDITION OF THE PROPERTIES. THIS ASSIGNMENT IS MADE BY AND ACCEPTED BY ASSIGNEE ON AN “AS IS, WHERE IS” BASIS. ASSIGNOR DISCLAIMS ALL WARRANTIES, INCLUDING:

AS TO THE FITNESS OR CONDITION OR MERCHANTABILITY OF THE WELLS, EQUIPMENT OR DISPOSAL FACILITIES CONVEYED;

AS TO THE PHYSICAL, OPERATIONAL, OR ENVIRONMENTAL CONDITION OF THE PROPERTIES;

AS TO THE OIL, GAS, AND OTHER HYDROCARBON OPERATIONS OF THE PROPERTIES COVERED BY THE TERMS AND CONDITIONS OF ANY LEASES OR OTHER AGREEMENTS THAT ARE A PART OF THE PROPERTIES; AND

AS TO THE ISSUANCE, REISSUANCE, OR TRANSFER OF ANY PERMITS RELATING TO ANY OF THE PROPERTIES.

Section 4. Covered Interests. Notwithstanding any contrary provision of this Assignment or the Contribution Agreement, to the extent that the assignment or conveyance of all or any part of the Properties shall be subject to any consent or approval requirements that are not satisfied or waived prior to the Effective Time, this Assignment shall not convey or be deemed to convey (until such consent or approval requirement has been satisfied or waived) any right, title or interest in and to the Properties to which such requirement relates (herein, a “Covered Interest”); however, (a) the full benefits of ownership of the Covered Interest shall be bargained, sold, conveyed, assigned and transferred unto Assignee hereunder as of the Effective Time, (b) Assignor shall hold legal title to the Covered Interest as nominee for the benefit of Assignee until such consent or approval requirement has been satisfied or waived, (c) Assignor

and Assignee shall each continue to use their respective commercially reasonable efforts to procure all required consents and approvals affecting the Covered Interest as soon as reasonably practicable after the Effective Time, and (d) immediately upon procurement of all required consents and approvals affecting the Covered Interest, all right, title and interest of Assignor in and to the Covered Interest shall thereupon automatically be bargained, sold, conveyed and assigned to Assignee hereunder, effective as of the Effective Time; it being expressly understood and agreed that no retention of any right, title or interest in and to any Covered Interest under this Section 4 or any consents or approvals affecting any Covered Interest shall be deemed or construed to be a breach or default of the limited warranty of title expressed in Section 2 of this Assignment or any provision of the Contribution Agreement.

Section 5. Effective Time Allocations. This Assignment shall be effective for all purposes as of the Effective Time. All production from or attributable to the Properties and all products and proceeds attributable thereto, and all other income, proceeds, receipts and credits with respect to the Properties pertaining to the period prior to the Effective Time shall be owned by and belong to Assignor, and all production from or attributable to the Properties and all products and proceeds attributable thereto and all other income, proceeds, receipts and credits respecting the same pertaining to the period from and after the Effective Time shall be owned by and belong to Assignee. Except as otherwise provided in the Contribution Agreement, all costs, expenses, liabilities and obligations attributable or chargeable to the Properties pertaining to the period prior to the Effective Time shall be retained by and shall remain the sole liability and obligation of Assignor and borne and discharged by Assignor, and all costs, expenses, liabilities and obligations attributable to the Properties pertaining to the period after the Effective Time are hereby assumed by and shall be the sole liability and obligation of Assignee and assumed and discharged by Assignee.

Section 6. The Contribution Agreement. This Assignment is made pursuant and subject to all of the terms and conditions of the Contribution Agreement. Except as otherwise provided in the Contribution Agreement, said terms and provisions shall survive the execution and delivery of this Assignment and shall not be merged therein. All terms and conditions of the Contribution Agreement are hereby incorporated in this Assignment by reference and made a part hereof for all purposes.

Section 7. Further Assurances. After the execution hereof, Assignor, without further consideration, will use its commercially reasonable efforts to execute, deliver and (if applicable) file or record or cause to be executed, delivered and filed or recorded, such good and sufficient instruments of conveyance and transfer and take such other action as may be reasonably required of Assignor to effectively vest in Assignee beneficial and record title to the Properties and, if applicable, to put Assignee in actual possession of the Properties. With respect to interests in Leases issued by the state or a subdivision thereof included within the Properties and that require filings with governmental agencies before they may be assigned, Assignor and Assignee will each use its commercially reasonable efforts to file the appropriate documents and take any other steps necessary to obtain official approval of the assignments. With respect to any Lease issued by the state or any agency thereof requiring consent to transfer, Assignor shall hold title thereto for the express benefit of Assignee until agency approval of such transfer has been obtained.

(a) The provisions of this Assignment will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof.

(b) All covenants and agreements in this Assignment bind and inure to the benefit of the heirs, successors, and assigns of Assignor and Assignee; are covenants running with the Lands; and are effective as stated whether or not the covenants and agreements are memorialized in assignments and other conveyances executed and delivered by the parties and their respective heirs, successors, and assigns from time to time.

(c) Recitation of or reference to any agreement or other instrument in this Assignment, including, without limitation, its exhibits, does not operate to ratify, confirm, revise, or reinstate the agreement or instrument if it has previously lapsed or expired.
