Subject to the further provisions below, Seller shall DEFEND, INDEMNIFY AND HOLD Buyer, its affiliates, and its/their directors, officers, employees, contractors, and representatives (which additional parties, together with Buyer, are hereinafter collectively referred to as the “Buyer Parties”) HARMLESS from and against any and all Claims arising from, out of or in connection with, or otherwise relating to:

(i) any inaccuracy of any representation or warranty of Seller set forth in this Agreement;

(ii) the Excluded Assets;

(iii) the Retained Obligations (as defined below and only to the extent of the applicable retention period) expressly excluding, however, matters assumed, indemnified against and waived by Buyer pursuant to Sections 7.6, 7.7 and 7.8 below; and

(iv) Seller’s breach of, or failure to perform or satisfy, any of its covenants and obligations hereunder.

THE INDEMNITIES UNDER THIS SECTION 3.3(b) ARE INTENDED TO APPLY REGARDLESS OF WHETHER ATTRIBUTABLE (IN WHOLE OR IN PART TO) THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY, LIABILITY WITHOUT FAULT, REGULATORY LIABILITY, STATUTORY LIABILITY, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHER FAULT OR RESPONSIBILITY OF SELLER, BUYER OR ANY OTHER PERSON OR PARTY, EXCEPT TO THE EXTENT CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF BUYER.

Seller shall not be liable to the Buyer Parties under clause 3.3(b)(i) (other than with regard to representations set forth in Sections 5.1(a), 5.1(b), 5.1(c), 5.1(d), 5.1(e), 5.1(f) and 5.1(g)) or clause 3.3(b)(iv) of this Section 3.3(b) with respect to any Claim unless (i) the amount of the Claim resulting from any separate fact, condition or event that constitutes a Claim is in excess of $35,000 (the “Individual Indemnification Threshold”) and (ii) the aggregate amount of all Claims by Buyer under this Agreement meeting the Individual Indemnification Threshold exceeds one and one-half percent (1.5%) of the Purchase Price under this Agreement (the “Aggregate Indemnification Threshold”).

Notwithstanding anything herein to the contrary, the cumulative obligation of Seller to Buyer Parties under clause 3.3(b)(i) (other than with regard to representations set forth in Sections 5.1(a), 5.1(b), 5.1(c), 5.1(d), 5.1(e), 5.1(f) or 5.1(g)) will be limited to twenty five percent (25%) of the Purchase Price (the “Indemnity Amount”). Seller’s obligation to indemnify the Buyer Parties pursuant to 3.3(b)(i) shall survive twelve (12) months after the Closing Date; provided, however Seller’s obligation to indemnify Buyer with respect to breaches of Seller’s representations and warranties in Sections 5.1(a), 5.1(b), 5.1(c), 5.1(d) 5.1(e), 5.1(f) and 5.1(g) shall survive the Closing forever; Seller’s obligation to indemnify the Buyer Parties for the Retained Obligations shall survive Closing for the period of time which the applicable Retained Obligation is retained by Seller pursuant to Section 3.4; and Seller’s obligation to indemnify the Buyer Parties pursuant to clause 3.3(b)(ii) of this Section 3.3(b) shall survive indefinitely. Seller’s obligation to indemnify Buyer Parties pursuant to clause 3.3(b)(iv) of this Section 3.3(b) shall survive two (2) years after the Closing Date (as applicable, the “Closing Period Termination Date”). The foregoing will not limit the rights of Buyer Parties to proceed against the Seller as provided herein after the Closing Period Termination Date with respect to Claims for which a Buyer Party has provided notice to Seller as provided in Section 3.3(d). Seller’s indemnity obligations shall, in each case, survive with respect to any indemnity claim asserted by Buyer prior to the expiration of the relevant Closing Period Termination Date.

(c) Buyer’s General Indemnification. Subject to Section 3.3(b), upon the Closing, Buyer shall defend, protect, indemnify and hold Seller, its affiliates, and its/their partners, members, managers, directors, officers, employees, contractors and representatives (which additional parties, together with Seller, are hereinafter collectively referred to as the “Seller Parties”) harmless from and against any and all Claims in any way arising from, out of or in connection with, or otherwise relating to: (i) any inaccuracy of any representation or warranty of Buyer set forth in this Agreement; (ii) Buyer’s breach of, or failure to perform or satisfy, any of its covenants and obligations hereunder; and (iii) the Assumed Obligations, AND THIS INDEMNITY IN THIS SECTION 3.3(c) IS INTENDED TO APPLY REGARDLESS OF WHETHER ATTRIBUTABLE (IN WHOLE OR IN PART TO) the sole, joint, concurrent or comparative negligence, strict liability, liability without fault, regulatory liability, statutory liability, breach of contract, breach of warranty or other fault or responsibility of Seller or any other person or party, except to the extent caused by the gross negligence or willful MISconduct of seller.

(d) Claims Procedures. Promptly upon a party becoming aware of any Claim with respect to which it believes it is entitled to indemnification hereunder, whether under this Section 3.3, Section 7.7, or the other provisions hereof, such party (an “Indemnified Party”) shall notify the other party (the “Indemnifying Party”) in writing of the existence and nature of such Claim, the identity of any third party claimants and a description of the damages and the amount thereof relating to such Claim (the “Claim Notice”). The Indemnified Party shall be responsible for the defense of any Claim unless the Indemnifying Party, upon reasonable notice, requests that the defense of a Claim be tendered to the Indemnifying Party. If:

(i) the defense of a Claim is so tendered and within ten (10) Business Days thereafter such tender is accepted by the Indemnifying Party; or

(ii) within ten (10) Business Days after the date on which the Claim Notice has been given pursuant to this Section 3.3(d), the Indemnifying Party shall acknowledge in writing to the Indemnified Party its obligation to provide an indemnity as provided in this Section 3.3 and assume the defense of the Claim;

then, except as hereinafter provided, the Indemnified Party shall not, and the Indemnifying Party shall, have the right to contest, defend, litigate or settle such Claim. The Indemnified Party shall have the right to be represented by counsel at the Indemnified Party’s expense, subject to the limitations hereof, in any such contest, defense, litigation or settlement conducted by the Indemnifying Party. The Indemnifying Party shall lose its right to defend and settle the Claim if it shall fail to diligently contest and defend the Claim after written notice or demand by the Indemnified Party. So long as the Indemnifying Party has not lost its right and/or obligation to contest, defend, litigate and settle as herein provided, the Indemnifying Party shall have the exclusive right to contest, defend and litigate the Claim and shall have the exclusive right, in its discretion exercised in good faith, and upon the advice of counsel, to settle any such matter, either before or after the initiation of litigation, at such time and upon such terms as it deems fair and reasonable; provided, that at least five (5) Business Days prior to any such settlement, written notice of its intention to settle shall be given to the Indemnified Party and the Indemnified Party shall have consented thereto, which consent shall not be unreasonably withheld, conditioned or delayed. All expenses (including without limitation attorneys’ fees) incurred by the Indemnifying Party in connection with the foregoing shall be paid by the Indemnifying Party; provided that, if the Indemnifying Party is the Seller, such expenses shall be paid or reimbursed to the Indemnified Party solely out of the Indemnity Amount and the Seller will have no obligation hereunder in excess of such amount. Notwithstanding the foregoing, in connection with any settlement negotiated by an Indemnifying Party, no Indemnified Party shall be required by an Indemnifying Party to (x) enter into any settlement that does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a full and complete release from all liability in respect of such claim or litigation, (y) enter into any settlement that attributes by its terms liability or wrongdoing to the Indemnified Party, or which establishes or acknowledges any liability of the Indemnified Party that is not satisfied by the Indemnifying Party, or would establish or acknowledge any future restrictions on the Indemnified Party, or (z) consent to the entry of any judgment that does not include as a term thereof a full dismissal of the litigation or proceeding with prejudice. No failure by an Indemnifying Party to acknowledge in writing its indemnification obligations under this Section 3.3 shall relieve it of such obligations to the extent they exist. If the Indemnifying Party fails to accept a tender of, or assume, the defense of a Claim pursuant to this Section 3.3(d), or if, in accordance with the foregoing, the Indemnifying Party shall lose its right to contest, defend, litigate and settle such a Claim or if there is a legal conflict, the Indemnified Party shall have the right, without prejudice to its right of indemnification hereunder, in its discretion exercised in good faith and upon the advice of counsel, to contest, defend and litigate such Claim, and may settle such Claim, either before or after the initiation of litigation, at such time and upon such terms as the Indemnified Party deems fair and reasonable; provided, that the Indemnified Party will not settle such Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. If, pursuant to this Section 3.3, the Indemnified Party so contests, defends, litigates or settles a Claim for which it is entitled to indemnification hereunder as hereinabove provided, the Indemnified Party shall be reimbursed by the Indemnifying Party for the reasonable attorneys’ fees and other expenses of defending, contesting, litigating and/or settling the Claim which are incurred from time to time, forthwith following the presentation to the Indemnifying Party of itemized bills for said attorneys’ fees and other expenses; provided that, if the Indemnifying Party is the Seller and the matter relates to a matter subject to indemnity by Seller pursuant to clause (i) of Section 3.3(b) (other than a breach of Sections 5.1(a), 5.1(b), 5.1(c), 5.1(d), 5.1(e), 5.1(f) or 5.1(g) hereof), such expenses shall be reimbursable to the Indemnified Party solely out of the Indemnity Amount and the Seller will have no obligation hereunder in excess of such amount.

(e) Subrogation. Following full indemnification as provided for hereunder, the Indemnifying Party shall be subrogated to all rights of the Indemnified Party with respect to all parties relating to the matter for which indemnification has been made and the Indemnified Party agrees to fully cooperate with the Indemnifying Party in exercising such subrogation rights, insofar and only insofar as the exercise of such subrogation rights does NOT (i) establish or acknowledge any liability of the Indemnified Party that is not satisfied by the Indemnifying Party, (ii) establish or acknowledge any future restrictions on the Indemnified Party, (iii) if the Indemnifying Party is the Seller, entitle Seller to any benefits or privileges of ownership of the Assets attributable to periods from and after the Effective Time.

(f) Insured Losses; Recoveries from Third Parties. The amount of any damages for which indemnification is provided under this Section 3.3, Section 7.7, or the other provisions hereof shall be net of any duplicative amounts recovered by the Indemnified Party under insurance policies or from unaffiliated third parties with respect to such damages. If an Indemnified Party receives an amount under insurance coverage or from an unaffiliated third party with respect to damages at any time subsequent to any indemnification provided by an Indemnifying Party pursuant to this Section 3.3, Section 7.7, or the other provisions hereof, then such Indemnified Party shall promptly deliver such amount (up to the amount of the indemnification payment made to such Indemnified Party regarding such matter) to the Indemnifying Party; provided, however, that such Indemnified Party shall be entitled to retain the amount of any payments made or costs or expenses incurred in connection with obtaining such payment. The obligation created by this Section 3.3(f), Section 7.7, or the other provisions hereof is an obligation to make repayment in the event and to the extent of a recovery from a third party and shall not delay an Indemnified Party’s right to repayment from the Indemnifying Party under this Section 3.3, Section 7.7, or the other provisions hereof.

(g) Characterization of Indemnification Payments. Buyer and Seller agree to treat any payment made under this Section 3.3, Section 7.7, or the other provisions hereof as an adjustment to the Purchase Price. Any indemnification hereunder will be determined on an after-tax basis (taking into account any actual tax benefits or detriments realized with respect to the damages for which the payment under this Section 3.3, Section 7.7, or the other provisions hereof is being made).

3.4 Retained Obligations. Provided that the Closing occurs, Seller shall retain indefinitely all obligations and liabilities related to (a) the Excluded Assets (b) all liability of Seller to third parties for personal injury, bodily injury, illness or death to the extent occurring prior to the Effective Time as a result of the operation of the Assets; (c) ad valorem, property, severance and similar taxes attributable to the period of time prior to the Effective Time retained by Seller; (d) all litigation existing or threatened Claims as of the Closing Date, to the extent it relates to the period of time prior to the Effective Time, including, without limitation, any matters described in Schedule 5.1(g), and (e) all obligations, liabilities and Claims relating to any pollutant, contaminant or toxic or hazardous materials that may have originated from, or been removed from, any of the Assets which were disposed of offsite of the Assets during the time period November 1, 2011 until Closing; for a period of two (2) years from Closing, and not thereafter, Seller shall retain (f) all obligations and liabilities of Seller for the payment or improper payment of royalties, overriding royalties, production payments, net profits interests, rentals and other similar payments attributable to Seller’s interests in the Leases, Units and ▇▇▇▇▇ relating to the Assets accruing prior to the Effective Time; (g) all obligations of Seller under the Contracts for (i) overhead charges related to periods prior to the Effective Time, (ii) costs and expenses incurred prior to the Effective Time for goods and services provided prior to the Effective Time, (iii) other payment obligations that accrue and become due prior to the Effective Time, (iv) joint interest ▇▇▇▇▇▇▇▇ and trade payables, and (vi) for alleged breach thereof prior to the Effective Time (collectively, the “Retained Obligations”).

3.5 Assumed Obligations. Upon Closing, Buyer shall assume all duties, obligations and liabilities of every kind and character with respect to the Assets actually conveyed to Buyer at Closing or the ownership or operation thereof (other than the Retained Obligations and other than liabilities for which Seller is responsible for under Section 3.3(b)), whether attributable to periods before or after the Effective Time, except as provided herein, including, without limitation, those arising out of (a) the terms of the Leases or Surface Interests, or the Personal Property or Assets, (b) suspense accounts, to the extent transferred to Buyer except as to Suspense Proceeds that should have been escheated under applicable law and interest and penalties thereon, (c) ad valorem, property, severance and other similar taxes or assessments based upon or measured by the ownership of the Assets or the production therefrom but only attributable to any period on or after the Effective Time, (d) the environmental or physical condition of the Assets, regardless of whether such environmental or physical condition arose before or after the Effective Time, (e) obligations to properly plug and abandon or re-plug or re-abandon or remove ▇▇▇▇▇, flowlines, gathering lines or other facilities, equipment or other personal property or fixtures comprising part of such Assets, (f) obligations to restore the surface of such Assets and obligations to remediate or bring the Assets into compliance with applicable Environmental Laws (including conducting any remediation activities that may be required on or otherwise in connection with activities on the Assets) regardless of whether such obligations or conditions or events giving rise to such obligations arose, occurred or accrued before or after the Effective Time, and (g) any other duty, obligation, event, condition or liability assumed by Buyer under the terms of this Agreement (collectively, the “Assumed Obligations”). When the retention period for a Retained Obligation ends, such Retained Obligation becomes an Assumed Obligation.

4. Taxes and Payables

4.1 Payment of Taxes. All real estate, use, ad valorem and personal property taxes and charges upon any of the Assets shall be prorated as of the Effective Time; provided that Buyer shall pay all such taxes attributable to the calendar year in which the Closing Date occurs to the extent due and payable after Closing, and at Closing, the Purchase Price will be decreased by Seller’s pro rata share of such items for the period prior to the Effective Time. If the actual amount of such items is not known as of the Closing Date and the final reconciliation of the Final Settlement Statement under Section 10.4, then Seller’s pro rata share of such items will be determined by using the rates and millages for the most recent year available and the assessed values for the calendar year immediately preceding the calendar year in which the Closing Date occurs, with appropriate adjustments for any known changes thereto. In no event shall the Final Settlement Statement be delayed pending determination of the proration of taxes pursuant to this Section 4.1.

4.2 Production Taxes. Seller shall be responsible for all oil and gas production taxes, and any other similar taxes applicable to Hydrocarbons produced and saved from or attributable to its interest in the Leases, ▇▇▇▇▇ and Units prior to the Effective Time (excluding Stock Hydrocarbons), and Buyer shall be responsible for all such taxes applicable to the Stock Hydrocarbons and all Hydrocarbons produced and saved from or attributable to the Leases, ▇▇▇▇▇ and Units from and after the Effective Time. For the avoidance of doubt, the taxes included in the preceding provisions of this Section 4.2 do not apply to any and all federal, state, local and foreign income and gains taxes attributable to the Assets or to the sale transactions resulting from the operation of this Agreement, including Texas margin tax, and, for purposes of such taxes, (i) any and all such income and gains taxes resulting from the ownership of the Assets prior to and including the Closing Date, including any income and gains taxes arising from the sale of the Assets pursuant to this Agreement, shall be the obligation and liability of the Seller, and Seller shall indemnify and hold Buyer harmless from such taxes, and (ii) any and all such income and gains taxes resulting from the ownership of the Assets after the Closing Date shall be the obligation and liability of the Buyer, and Buyer shall indemnify and holder Seller harmless from such taxes.

4.3 Occasional Sale of Assets. Both parties believe that the sale of the Assets is an occasional sale exempt from sales or use taxes. If any such taxes are assessed against the transaction, both parties will cooperate and use their commercially reasonable efforts (at no cost to Seller) to attempt to eliminate or reduce such taxes. If unsuccessful, Buyer shall be responsible for any such taxes. In that event, Buyer shall pay Seller any such state and local sales or use taxes, and Seller shall remit such amount to the appropriate taxing authority in accordance with applicable law. Any reasonable legal expenses incurred by Seller at Buyer’s request to reduce or avoid any of the aforementioned taxes attributable to Buyer, shall be paid or reimbursed by Buyer.

4.4 Tax Deferred Exchange. Seller and Buyer agree that this transaction may be completed as a like-kind exchange under Section 1031 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) and that each party will cooperate in completing the sale as a like-kind exchange. Either of both Seller or Buyer may, at or before the Closing, elect to affect a tax deferred exchange of the Assets for other qualifying properties (hereinafter collectively called the “Exchange Property” in accordance with the following:

(a) In the event Seller makes such an election, Seller shall notify and instruct Buyer, on or before the Closing Date, to have the Purchase Price paid to a qualified intermediary (as that term is defined in Treasury Regulation Section 1.1031(k)-1(g)(4)(iii)) until Seller has designated the Exchange Property. The Exchange Property shall be designated by Seller and acquired by the qualified intermediary with the time periods prescribed by Section 1031(a)(3) of the Internal Revenue Code. In the event Seller fails to designate and the qualified intermediary fails to acquire the Exchange Property with such time periods, the agency or trust shall terminate and the proceeds then held by the qualified intermediary shall be paid in accordance with the terms of the agreements entered into between Seller and such qualified intermediary.

(b) In the event Buyer makes such an election, Buyer shall notify and instruct Seller, on or before the Closing Date, to have the Assets conveyed to a qualified intermediary or an exchange accommodation titleholder (as that term is defined in Rev. Proc. 2000-37 issued effective September 15, 2000).

(c) The rights and responsibilities of Seller, Buyer and the qualified intermediary or exchange accommodation titleholder shall be documented with such agreements containing such terms and provisions as shall be reasonably determined by Seller and Buyer to be necessary to accomplish a tax deferred exchange under Section 1031 of the Internal Revenue Code, subject, however, to the limitations on costs and liabilities of Buyer and Seller set forth below. If Seller makes a tax deferred exchange election, Buyer shall not be obligated to pay any additional costs or incur any additional obligations in the acquisition of the Assets. If Buyer makes a tax deferred exchange election, Seller shall not be obligated to pay any additional costs or incur any additional obligations in the consummation of the transactions contemplated in this Agreement. Any such tax deferred exchange election by either party, shall be effected through an assignment of this Agreement, or rights under this Agreement, to a qualified intermediary or an exchange accommodation titleholder, but such assignment shall not affect the duties, rights or obligations of the parties under this Agreement, except as expressly set forth in this Section 4.4.

(d) Should either Seller or Buyer make such an election and should the tax deferred exchange fail or be disallowed by the Internal Revenue Service for any reason, the non-electing party’s sole responsibility and liability to the electing party shall be to take such actions as are required by Subsections (a), (b) or (c) above and such non-electing party shall have no other responsibility or liability whatsoever to the electing party; and the electing party shall release, indemnify, defend and hold harmless the non-electing party from any responsibility or liability related to such election except for such actions as may be required by Subsections (a), (b) or (c) above.

(e) Notwithstanding Subsections (a) through (d) above, the Closing shall not be delayed or affected by reason of any tax deferred exchange election nor shall consummation or accomplishment of a tax deferred exchange be a condition precedent or condition subsequent to the exchanging party’s duties, rights and obligations under this Agreement and the exchanging party’s failure or inability to consummate a tax deferred exchange for any reason shall not excuse or release the exchanging party from its duties, rights and obligations under this Agreement.

(a) lessor’s royalties, non-participating royalties, overriding royalties, division orders, sales, gathering, transportation and transportation-related services contracts containing customary terms and provisions, reversionary interests, and similar burdens if the net cumulative effect of such burdens does not operate to reduce the Net Revenue Interest in any Well, Lease, Unit, or PUD to an amount less than the Net Revenue Interest set forth on Exhibit “A”, or increase the Working Interest of any Well, Lease, Unit or PUD from that set forth in Exhibit “A” without a corresponding increase in the Net Revenue Interest;

(j) any other privilege, lien, claim, charge, encumbrance, contract, agreement, instrument, obligation, defect, or irregularity affecting the Assets relating to obligations not yet in default, which, individually or in the aggregate, does not interfere materially with the value or the use of the Assets, as currently used by Seller, does not prevent Buyer from receiving the proceeds of production from the Assets, does not reduce the Net Revenue Interest of any of the ▇▇▇▇▇, Leases, Units or PUDs to less than the Net Revenue Interest set forth on Exhibit “A” and does not obligate Buyer to bear costs and expenses relating to the maintenance, development and operation of any of the ▇▇▇▇▇, Leases, Units or PUDs in any amount greater than the Working Interest set forth on Exhibit “A” (unless the Net Revenue Interest for such Well, Leases, Units or PUDs is greater than the Net Revenue Interest set forth in Exhibit “A” in the same proportion as any increase in such Working Interest);

(k) any privilege, mortgage, lien or encumbrance to be released at or prior to Closing.

6.4 Notice of Title Defects; Title Defect Valuation.

(a) If Buyer discovers any Title Defect affecting an Asset, Buyer shall promptly notify Seller of such alleged Title Defect. To be effective, such notice (a “Title Defect Notice”) must (i) be in writing, (ii) be received prior to the expiration of the Examination Period, (iii) describe the Title Defect in reasonable detail (including any alleged variance in the Net Revenue Interest or Working Interest), (iv) identify the specific Asset or Assets affected by such Title Defect and (v) include the Title Defect Value, as reasonably determined by Buyer acting in good faith. Upon receipt of a timely Title Defect Notice, upon request by Seller, Buyer shall promptly deliver to Seller copies of all data, records, title reports, opinions and other information in Buyer’s possession or control bearing upon or relating to the alleged Title Defect and its determination of the Title Defect Value.

(b) The value attributable to each Title Defect (the “Title Defect Value”) shall be determined based upon the criteria set forth below:

(i) If the Title Defect is a privilege or lien upon an Asset, the Title Defect Value is the amount necessary to be paid to remove fully the privilege or lien from the affected Asset.

(ii) If the Title Defect asserted is that the Net Revenue Interest attributable to a Well, Lease, Unit or PUD is less than that stated in Exhibit “A” (and there is a corresponding and proportionate decrease in Working Interest), then the Title Defect Value is the product of the Allocated Value attributed to such Asset, multiplied by a fraction, the numerator of which is the difference between the Net Revenue Interest applicable thereto set forth in Exhibit “A” and the actual Net Revenue Interest, and the denominator of which is the applicable Net Revenue Interest stated in Exhibit “A”.

(iii) If the Title Defect represents an obligation, encumbrance, burden or charge upon the affected Asset (including any increase in Working Interest for which there is not a proportionate increase in Net Revenue Interest) and for which the economic detriment to Buyer is unliquidated, the amount of the Title Defect Value shall be determined by taking into account the Allocated Value of the affected Asset, the portion of the Asset affected by the Title Defect, the legal effect of the Title Defect, and the potential discounted economic effect of the Title Defect over the life of the affected Asset.

(iv) If a Title Defect does not adversely affect an Asset throughout the entire productive life of such Asset or all depths as to all depths from below the base of the Delaware Group Sands formation to the top of the Wolfcamp “Red” Sand formation or their stratigraphic equivalents as reflected on by the stratigraphic markers on Schedule 6.2 or their stratigraphic equivalents such fact shall be taken into account in determining the Title Defect Value; provided, however, that no Title Defect shall be asserted by Seller with respect to the Chevy 17 Well and Big ▇▇▇ 29 #1 Well solely because Seller does not own marketable title below the base of the 3rd Bone Springs Formation.

(v) The Title Defect Value of a Title Defect shall be determined without duplication of any costs or losses included in another Title Defect Value hereunder.

(vi) Notwithstanding anything herein to the contrary, in no event shall a Title Defect Value exceed the Allocated Value of the ▇▇▇▇▇, Leases and other Assets affected thereby.

(vii) Such other factors as are reasonably necessary to make a proper evaluation.

(viii) If the Title Defect is an un-obtained consent, then the Title Defect Value shall be the Allocated Value of the affected Assets and the threshold and deductible for Title Defects described in Section 6.7 shall not be applicable.

(ix) If the Title Defect concerns a deficiency of net mineral acres, then the Title Defect Value shall be calculated by the number of net mineral acres by which Seller is deficient, multiplied by the per net mineral acre value described in Schedule 6.4(b)(ix).

(x) If the Title Defect concerns a remaining primary term shorter than three (3) months after the Closing date for a Lease not currently held by production, the Title Defect Value shall be the Allocated Value for such Lease, and if no Allocated Value is provided for such Lease, then the Title Defect Value shall be the applicable per net mineral acre value for such Lease multiplied by the number of net mineral acres covered by such Lease, and the threshold and deductible for Title Defects described in Section 6.7 shall not be applicable.

6.5 Remedies for Title Defects. Subject to Section 2.4(b)(vii), 6.7 and 10.1(b)(iv) (and except with regard a breach of the special warranty of title under the Assignment), the following shall be Buyer’s sole and exclusive remedy with respect to Title Defects:

(a) Upon the receipt of a Title Defect Notice from Buyer asserting an alleged Title Defect, Seller shall have the option, but not the obligation, to attempt to cure such Title Defect at Seller’s sole cost at any time prior to the Closing.

(b) With respect to any alleged Title Defect that is not reasonably cured on or before the Closing and the Title Defect Value for such Asset equals or exceeds the Allocated Value for such Asset, Seller shall have the option, but not the obligation, to exclude the affected Asset from the Assets delivered at Closing and the Purchase Price shall be reduced by the Allocated Value of such affected Asset.

(c) With respect to each alleged Title Defect that is not reasonably cured on or before the Closing and the affected Asset has not been excluded from the transaction pursuant to Section 6.5(b), the Purchase Price hereunder will be reduced by an amount equal to the Title Defect Value thereof, and giving effect to the criteria set out in Section 6.4(b) above.

(d) (i) if Seller has not agreed on or before Closing upon the validity of an asserted Title Defect, or has not agreed upon the Title Defect Value attributable thereto, or (ii) if Buyer has not agreed upon whether a Title Defect has been reasonably cured, then either party shall have the right to elect by written notice, delivered before or after Closing, to have the validity of such Title Defect, such Title Defect Value or the sufficiency of Seller’s cure determined by an Independent Expert pursuant to Section 8. The Assets to which such dispute relates shall, nonetheless, be assigned and conveyed to Buyer at Closing, but until resolved by such Independent Expert, the Title Defect Value asserted by Buyer with regard thereto shall be withheld from the Closing payment and retained by Buyer until such dispute is finally resolved as provided in Section 8 hereof, which shall include, without limitation, an award of the amounts withheld from Closing attributable to such Title Defect. To the extent the Independent Expert is determining the validity of a Title Defect, Seller shall have ninety (90) days from the date the Independent Expert determines that a Title Defect exists to cure such Title Defect.

(e) Any Title Defect cured by Seller or for which Buyer receives a Purchase Price adjustment or payment pursuant to this Section 6.5, shall constitute a Permitted Encumbrance hereunder and under the Assignment.

6.6 Title Benefits.

(a) Subject to Section 6.7, Seller shall be entitled to an upward adjustment to the Purchase Price with respect to all Title Benefits of which Seller provides Buyer notice (a “Title Benefit Notice”) in writing prior to the expiration of the Examination Period in an amount (the “Title Benefit Value”) mutually agreed upon by the parties determined in accordance with the criteria set forth in Section 6.4(b). Notwithstanding the foregoing, if the Title Defect Value is disputed, no upward adjustment to the Purchase Price shall be made for Title Benefits until the Title Defect Value has been determined in accordance with Section 6.5. A party identifying a Title Benefit affecting the Assets shall promptly deliver such a Title Benefit Notice to the other party in the same form and including the same information as specified in Section 6.4(a) for a Title Defect Notice. The term “Title Benefit” shall mean Seller’s Net Revenue Interest in any Well that is greater than the Net Revenue Interest set forth in Exhibit “A”, or Seller’s Working Interest in any Well that is less than the Working Interest set forth in Exhibit “A” (without a proportionate decrease in the Net Revenue Interest). A Title Benefit Value agreed to by Buyer and Seller shall offset the aggregate Title Defects Values only, and shall not be a direct increase to the Purchase Price.

(b) If, with respect to an asserted Title Benefit, the parties have not agreed on the validity of the Title Benefit or the Title Benefit Value attributable thereto on or before Closing, then either party shall have the right to elect by written notice to the other party to have the validity of the Title Benefit and/or the Title Benefit Value determined by an Independent Expert pursuant to Section 8. If the validity of the Title Benefit and/or the Title Benefit Value is not determined pursuant to this Agreement by the Closing, the Title Benefit Value determined by Seller, acting reasonably and in good faith, shall offset the aggregate Title Defect Value.

6.7 Limitation of Remedies for Title Defects; Title Benefits. Notwithstanding anything to the contrary contained in this Agreement, if (a) the Title Defect Value for a given Title Defect, or the Title Benefit Value of a given Title Benefit, does not exceed $35,000, then no claim or adjustment to the Purchase Price shall be made for such Title Defect or Title Benefit; (b) if the aggregate net value of all uncured Title Defects does not exceed 3/4ths of one percent (0.75%) of the Purchase Price under this Agreement (the “Aggregate Title Threshold”), then no adjustment of the Purchase Price shall be made therefor and (c) if the aggregate net value of all uncured Title Defects and Title Benefits exceeds the Aggregate Title Threshold (prior to any adjustments thereto), then the Purchase Price shall only be adjusted by the amount of excess net value of all uncured Title Defects and Title Benefits.

7. Environmental Matters

7.1 Environmental Review.

(a) Buyer shall have the right to conduct an environmental review of the Assets prior to the expiration of the Examination Period (“Buyer’s Environmental Review”). Seller shall provide Buyer such access as it may reasonably request to the Assets (if operated by Seller) and the environmental data in Seller’s files for the Assets. With respect to Assets not operated by Seller, Seller agrees, at no cost or expense to Seller, to request that the operator of such Assets grant Buyer (and shall use commercially reasonable and diligent efforts to obtain for Buyer) such access. Except in connection with any applicable representations and warranties under this Agreement, Seller makes no representations or warranties whatsoever as to the accuracy, completeness or reliability of any such environmental information, and Buyer relies and depends on and uses any and all such environmental information, review or inspection exclusively and entirely at its own risk and without any recourse to Seller whatsoever.

(b) The cost and expense of Buyer’s Environmental Review shall be borne solely by Buyer. The scope of work comprising Buyer’s Environmental Review conducted at or upon the Leases, Units and ▇▇▇▇▇ shall not include any intrusive test or procedure without the prior written consent of Seller. Buyer shall (i) consult with Seller before conducting any work comprising such Buyer’s Environmental Review, (ii) perform all such work in a safe and workmanlike manner and so as to not unreasonably interfere with operations of the Assets, and (iii) comply with all applicable laws, rules, and regulations of applicable Governmental Authority. Seller shall be responsible for obtaining any third party consents that are required in order to perform any work comprising Buyer’s Environmental Review. Buyer shall consult with Seller prior to requesting each such third party consent and Seller shall reasonably cooperate with Buyer in connection with obtaining such consent. Seller shall have the right to have a representative or representatives accompany Buyer at all times during Buyer’s Environmental Review, and Buyer shall give Seller notice not more than seven (7) days and not less than 24 hours before any visits by Buyer to the Assets, and Buyer shall seek and obtain Seller’s prior consent (which shall not be unreasonably withheld) before it enters upon the Assets. With respect to any samples taken in connection with Buyer’s Environmental Review, Buyer shall take split samples, providing one of each such sample, properly labeled and identified, to Seller. Buyer hereby agrees to release, defend, indemnify and hold harmless Seller Parties from and against all Claims arising from, out of or in connection with, or otherwise relating to, Buyer’s Environmental Review, REGARDLESS OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT ANY SELLER PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), STRICT LIABILITY, REGULATORY LIABILITY, STATUTORY LIABILITY, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHER FAULT OR RESPONSIBILITY OF A SELLER PARTY OR ANY OTHER PERSON OR PARTY. Provided, however, the mere discovery of information by Buyer in connection with Buyer’s Environmental Review relating to the condition of the Assets prior to Buyer’s Environmental Review, shall not itself give rise to an indemnity obligation owed by Buyer to Seller pursuant to this Section 7.1(b).

(c) Unless otherwise required by applicable law, Buyer shall treat all matters revealed by Buyer’s Environmental Review, including, without limitation, any analyses, compilations, studies, documents, reports or data prepared or generated from such review (the “Environmental Information”), as confidential, and Buyer shall not disclose any Environmental Information to any Governmental Authority or other third party without the prior written consent of Seller except as hereafter provided or to the extent required by applicable law.

The Environmental Information shall be disclosed by Buyer to only those persons who need to know the Environmental Information for purposes of evaluating the transaction contemplated by this Agreement, and who agree to be bound by the terms of this Section 7.1(c). If Buyer or any third party to whom Buyer has provided any Environmental Information is requested, compelled or required to disclose any of the Environmental Information by a court or other Governmental Authority, or disclosure is otherwise required under applicable law, Buyer shall provide Seller with prompt notice sufficiently prior to any such disclosure so as to allow Seller to file for any protective order, or seek any other remedy, as it deems appropriate under the circumstances. If this Agreement is terminated prior to the Closing, upon Seller’s request Buyer shall promptly deliver the Environmental Information, and all copies thereof and works based thereon, to Seller, which Environmental Information shall become the sole property of Seller; provided, however, that Buyer may retain copies thereof in the event of a dispute between Buyer and Seller arising from or relating to such termination. Upon request, Buyer shall provide copies of the Environmental Information to Seller without charge. The terms and provisions of this Section 7.1(c) shall survive any such termination of this Agreement, notwithstanding anything to the contrary.

9. Additional Covenants

9.1 Operations Prior to Closing. After the date of this Agreement and prior to the Closing, as to any of the Assets operated by Seller, Seller shall use, operate and maintain the Assets in substantially the same manner in which they have been used, operated and maintained prior to this Agreement, in accordance with all applicable laws and regulations, in accordance with common industry standards and as a reasonable and prudent operator. During the period from the Effective Time until Closing, Seller shall have no liability to Buyer for Claims sustained or liabilities incurred with respect to the Assets, REGARDLESS OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY, REGULATORY LIABILITY, STATUTORY LIABILITY, BREACH OF CONTRACT (EXCLUDING BREACH OF THIS AGREEMENT BY SELLER), BREACH OF WARRANTY OR OTHER FAULT OR RESPONSIBILITY OF SELLER OR ANY OTHER PERSON OR PARTY, EXCEPT TO THE EXTENT CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SELLER. After the date hereof and prior to Closing, Seller may (without Buyer’s consent) enter into agreements or transactions in relation to the Assets which (a) individually involve a reasonably anticipated cost of less than $50,000, individually, and do not impose any area of mutual interest, non-compete, drilling or surface restrictions, and (b) are entered into in the ordinary course of business, consistent with past practices. With Closing, Seller is relieved of and shall not be obligated for any expenditures attributable to periods after the Effective Time, and shall recover any such charges and expenses as part of the Closing Statement and Final Settlement Statement adjustments, as appropriate. Except with respect to those matters described above, if any material expenditure, contract or agreement is proposed or contemplated, Seller shall promptly submit such proposal to Buyer for concurrence with Seller’s recommendation. Buyer will make any required election under its independent evaluation and, if the Closing occurs and such Assets are conveyed to Buyer, shall assume the cost and risk of any consequences which arise as a result of Buyer’s election to participate or Buyer’s failure to timely elect or election to not participate in or not approve an operation and not pay such expenditure, without regard to whether Closing occurs. Failure of Buyer to timely respond to an election request (which election request shall be provided to Buyer no later than ten (10) business days prior to the date such election must be made), shall be deemed an election by Buyer to accept and agree to the proposed election proposed (and participate in the proposed operation). Additionally, after the execution of this Agreement and prior to Closing, Seller shall have the right to make any changes, repairs or modifications to the Assets, and incur any related expenditure deemed necessary by Seller, insofar as the same is necessary to prevent or respond to an emergency involving serious risk of loss of or damage to life, property, or the environment, or maintain economic production from any Lease, Well or Unit. With regard to the preceding sentence, Seller shall notify Buyer as soon as possible of the emergency and Seller’s response thereto and shall have the right to cause or effect such expenditure or action with or without Buyer’s approval, and recover such costs in the Closing Statement or Final Settlement Statement adjustments, as appropriate. Prior to Closing, Seller shall (i) consult with and advise Buyer regarding all material matters concerning the operation, management, and administration of the Assets and (ii) obtain Buyer’s written approval before voting or making any election under any operating, unit, joint venture, or similar agreement. Furthermore, Seller will not, without the prior written consent of Buyer, (x) enter into any agreement or arrangement transferring, selling, abandon, forfeit, or encumbering any of the Assets, (y) grant any preferential or other similar right to purchase any of the Assets, enter into any areas of mutual interest, non-compete agreements, drilling or surface restrictions, (z) enter into any new production sales, gathering, transportation, treating, or processing contract extending beyond the Closing Date and not terminable on thirty (30) days’ notice or less, without penalty or liability, (aa) amend or terminate any Contract, (bb) take any other action or election with regard to the Assets equal to or in excess $50,000, net to the interest in the Assets to be conveyed Buyer. Promptly after execution of this Agreement, Seller shall notify the holders of the Consents of the transactions contemplated herein and request their consent. Buyer shall have the right to review and approve the form of such notices, such approval not to be unreasonably withheld. Buyer and Seller each agree to reasonably cooperate with efforts to obtain such required Consents.

9.2 Preferential Rights to Purchase and Consents.

(a) Notice. Promptly after execution of this Agreement (and in no event later than five (5) days after execution), Seller shall (i) use the Allocated Values set forth on Schedule 2.3 to provide each required Preferential Right notification, in accordance with the terms thereof, and (ii) send to any party whose consent or approval is required in connection with the transfer and conveyance of the Assets to Buyer as contemplated herein a written request for such consent or approval, in accordance with the requirements of the Lease, Contract, agreement, instrument, or provision giving rise to the need for such consent or approval.

(b) Third Party Exercise. If a third party gives valid and timely notice of its exercise of a Preferential Right to purchase any of the Assets, the affected Assets will not be sold to Buyer and the Purchase Price will be adjusted by the Allocated Value of the affected Assets. If Buyer has allocated a positive Allocated Value to the Preferential Right Asset, the Purchase Price will be reduced by the dollar amount of the positive allocation. If Buyer has allocated a negative Allocated Value to the Preferential Right Asset, the Purchase Price will be increased by the absolute value of the negative allocation. Buyer remains obligated to purchase the remainder of the Assets not affected by exercised Preferential Rights without reduction to the Purchase Price attributable to such unaffected Assets in accordance with the terms of this Agreement.

(c) Third Party Failure to Purchase. If a third party gives notice of its intent to exercise a Preferential Right to purchase any of the Assets, but does not close the purchase for any reason either before or within a reasonable time after Closing, or if a third party fails to give valid and timely notice of its exercise of a Preferential Right to purchase any of the Assets within the express time provided for such notice, then there shall promptly be an additional Closing between Seller and Buyer for such portion of the Assets pursuant to the terms of this Agreement, by which Seller will transfer the affected portion of the Assets to Buyer and Buyer will pay Seller that portion of the Purchase Price attributable thereto (or in the case of a negative allocation, Seller will refund the absolute value of the negative amount to Buyer) (in each case subject to adjustment in accordance with Section 2.4).

9.3 Compliance. From and after Closing, Buyer shall comply with contracts, agreements, Leases and applicable laws, ordinances, rules and regulations and shall promptly obtain and maintain all permits required by Governmental Authorities in connection with the Assets purchased.

9.4 Employees. Except for those persons listed on Schedule 9.4, Buyer shall not contact or communicate with Seller’s employees until Closing; provided, however, Buyer shall be permitted and allowed to discuss employment or offer to employ or employ any non-employee contract field personnel and contract land services providers promptly after execution of this Agreement; and provided, further, that this provision shall not apply to any employee of Seller who responds to a public posting or advertisement for employment with Buyer.

9.5 Non-Compete.

Acceptance by Buyer to particular exceptions to this clause will not constitute waiver of this clause. Seller acknowledges that the restrctions and covenants set forth herein constitute valuable consideration for Buyer’s agreement to enter into this Agreement and consummate the transactions contemplated herein, and Buyer would not have entered into this Agreement but for Seller’s agreement to the provisions of this Section 9.5. It is also agreed that in addition to any other rights or remedies that Buyer have have at law or in equity, Buyer shall have the continuing right to specific enforcement and injunctive relief, to enforce the provisions of this Section 9.5. Seller shall cause its affiliates and subsidiaries to comply with, assume and be bound by the provisions of this Section 9.5, and Seller shall be jointly and severally liable for any breach of these provisions by any of its affiliates or subsidiaries. Provided, however, this Section 9.5 shall not apply to Assets retained by Seller because they have been excluded from the transaction contemplated by this Agreement pursuant to and in compliance with the terms of this Agreement.

(a) By Seller if any condition set forth in Section 10.1(a) has not been satisfied or waived by Seller by the Closing Date; provided that Seller is not in material breach of this Agreement;

(b) By Buyer if any condition set forth in Section 10.1(b) has not been satisfied or waived by Buyer by the Closing Date or for a condition set forth in Section 10.1(b) that must be satisfied on a date prior to the Closing Date and such condition has not been waived by Buyer by such date; provided that Buyer is not in material breach of this Agreement;

(d) By either Buyer or Seller if Closing has not occurred on or before July 15, 2013, unless Buyer and Seller agree in writing to extend Closing to a date later than July 15, 2013.

If Seller, through no fault of Buyer, fails, refuses, or is unable for any reason not permitted by this Agreement to close the sale pursuant hereto, the Deposit shall, except as otherwise provided herein, be disbursed from the Escrow Account to Buyer and subject to Section 11.19 Buyer shall have the right to seek all remedies available at law or equity. Notwithstanding the foregoing, if this Agreement is terminated by either Buyer or Seller under Section 10.3(b), Section 10.3(d) or 10.3(e) or by mutual agreement of Buyer and Seller under Section 10.3(c), the Deposit (including, without limitation, any interest and earnings thereon) shall be disbursed from the Escrow Account to Buyer and neither party shall have any further liability whatsoever to the other party pursuant to this Agreement.

10.4 Final Adjustments. Within one hundred twenty (120) days after the date of Closing, Seller shall prepare, in consultation with Buyer, a Final Settlement Statement, acting reasonably and in good faith (the “Final Settlement Statement”), setting forth (i) the final adjustments to the Purchase Price provided in Section 2.4 and (ii) any other adjustments arising pursuant to this Agreement or to which the parties mutually agree. Seller may set off any resulting amount due to Buyer against any amount or sum that Buyer may otherwise owe to Seller under the terms of this Agreement. Seller shall submit the Final Settlement Statement to Buyer, along with copies of third party vendor invoices, or other evidence of expenses agreed to by Buyer and Seller.

After approval of the Final Settlement Statement, Buyer or Seller will send a check or invoice to Seller or Buyer, as the case may be, for the net amount reflected therein as owed by such party. If Buyer and Seller are unable to agree to all adjustments within thirty (30) days after Buyer’s written objection to the Final Settlement Statement submitted by Seller, adjustments which are not in dispute shall be paid by Buyer or Seller, as the case may be, at the expiration of such thirty day period and either party may submit such disagreement to an Independent Expert selected in the manner provided in Section 8 for resolution. An Independent Expert selected with respect to any dispute relating to the Final Settlement Statement need not be the Independent Expert selected pursuant to Section 8 with respect to a Title Defect or Environmental Defect, if any such person had been previously selected with respect to such matters.

11. Miscellaneous

11.1 Oil, Gas and End Product Imbalances. Regardless of whether Seller is overproduced or underproduced as to its share of total oil, condensate, gas or end product production, any balancing obligation or credit arising from such over or underproduction, and any pipeline imbalance, in each case determined as of the Effective Time (an “Imbalance”) shall transfer to Buyer as of the Effective Time, and Seller shall have no further liability therefor nor benefit therefrom (whichever the case may be) as of the Effective Time. If Seller is a party to a gas balancing agreement(s) or other reconciliation obligations pursuant to any commingling authority covering all or a portion of the Assets, Buyer shall assume all rights and duties of Seller pursuant thereto. If any of the Assets are not covered by a gas balancing agreement or other reconciliation obligations pursuant to any commingling authority, Buyer shall fulfill its obligations under this provision in accordance with applicable law. Buyer agrees to indemnify, defend and hold Seller and Seller Parties harmless against any and all Claims arising directly or indirectly out of Buyer’s failure to fulfill its obligation under this provision, insofar and only insofar as the Buyer’s aggregate liability under this indemnity does not exceed (and Buyer’s liability is expressly limited and capped at) an aggregate amount equal to the downward adjustments to the Purchase Price credit to Buyer at Closing attributable to the Imbalance. Buyer and Seller will settle all Imbalances as between themselves using a settlement price based on $85.00 a barrel for oil, $85.00 per barrel for condensate, $3.25 per mcf for gas, and $32.00 per barrel for end product (NGL’s).

11.2 Insurance. With regard to any Seller-operated properties:

(a) Seller and Buyer acknowledge that insurance coverage for the Assets and the operations in which the Assets have been used has been provided, in part, under insurance programs arranged and maintained by Seller for itself and, if applicable, its subsidiaries and affiliates (such policies are herein called “Seller Policies”).

(b) Seller agrees that during the period between the date of this Agreement and the Closing Date, Seller shall maintain insurance with respect to the Assets with financially sound and reputable insurance companies, in such amounts, with such deductibles and covering such risks as are customarily carried by reasonable, prudent operators of similar properties.

(c) Seller and Buyer agree that, as of the Closing Date, all of the Seller Policies shall cease to apply to the Assets and the operations in which the Assets are used and that Buyer shall make no claims under the Seller Policies with respect to any matter whatsoever, whether arising before or after the Closing Date.

(d) In the event that any Claim is hereafter made under or with respect to any of the Seller Policies by Buyer or any of its affiliates, but not an unrelated third party, Buyer shall indemnify and defend Seller and Seller Parties against and shall hold them harmless from such Claim and all costs and expenses (including, without limitation, attorney’s fees and court costs) related thereto.

11.3 Casualty Loss of Assets. If, after execution of this Agreement and prior to Closing, a portion of the Assets is damaged or destroyed by a Casualty Loss, Seller may at its sole option, prior to Closing, repair the damage at its cost or reduce the Purchase Price by the amount of the damage, or if Buyer agrees, withdraw the damaged Asset from the sale and reduce the Purchase Price by the Allocated Value thereof. Should Buyer and Seller not agree as to the amount of such price reduction such dispute shall be submitted to the Independent Expert for determination. The term “Casualty Loss” shall mean physical damage to, loss of, condemnation or other taking by a governmental authority of any part of, an Asset that (a) occurs between execution of this Agreement and Closing, (b) is not the result of normal wear and tear, mechanical failure or gradual structural deterioration of materials, equipment and infrastructure, reservoir changes, or downhole failure (including, without limitation, downhole failure arising or occurring during drilling or completing operations, junked or lost holes or sidetracking or deviating a well) and (c) exceeds Thirty Five Thousand Dollars ($35,000) in value.

11.4 Books and Records. Seller shall deliver the Records to Buyer at Closing or within a reasonable time thereafter, if such Records useful or necessary for Seller to Seller to provide Services under the Transition Services Agreement, then fifteen (15) days after termination of the Transition Services Agreement.

11.5 Publicity. Seller and Buyer shall consult with each other with regard to all press releases or other public or private announcements made concerning this Agreement or the transactions contemplated hereby, and except as may be required by applicable laws or the applicable rules and regulations of any Governmental Authority or stock exchange, neither Buyer nor Seller shall issue any such press release or other publicity without the prior written consent of the other party, which shall not be unreasonably withheld. Except as may be required by applicable laws or the applicable rules and regulations of any Governmental Authority or stock exchange, no such press release shall include any reserve estimates.

11.6 Assignment. Prior to Closing, neither Party may assign any rights acquired hereunder or delegate any duties assumed hereunder without the prior written consent of the other Party; provided, however, that Buyer may assign this Agreement to any wholly owned subsidiary without Seller’s consent; and any other such transfer, assignment, sublease or delegation without the other Party’s consent shall be null and void, ab initio. Notwithstanding anything herein to the contrary, the assigning Party shall remain responsible to Seller for all obligations and liabilities under this Agreement and under the Assignment, until expressly released by the non-assigning Party in writing.

11.7 Entire Agreement; Amendment. This Agreement constitutes the entire agreement between Seller and Buyer with respect to the transactions contemplated herein, and supersedes all prior oral or written agreements, commitments, and understandings between the parties. No amendment shall be binding unless in writing and signed by both parties. Headings used in this Agreement are only for convenience of reference and shall not be used to define the meaning of any provision. This Agreement is for the benefit of Seller and Buyer and their respective successors, representatives, and assigns and not for the benefit of third parties.
