Article II

Purchase Price

Section 2.01 Purchase Price. The total consideration for the purchase, sale and conveyance of the Assets to Buyer is Buyer’s payment to Seller of the sum of Three Hundred Twenty Three Million Four Hundred Twenty Six Thousand Four Hundred Sixteen Dollars ($323,426,416.00) and, in connection with the New Leases, Nine Million Two Hundred Forty Thousand Four Hundred Eighty Nine Dollars ($9,240,489.00), (the sum of the foregoing being the “Base Price”), as shall be adjusted in accordance with the provisions of this Agreement. The purchase price for the Assets shall be equal to the Base Price after all adjustments provided for in this Agreement are made to the Base Price pursuant to and in accordance with this Agreement (the “Purchase Price”). The Purchase Price shall be paid to Seller at Closing (as defined in Section 10.01) by means of a completed federal funds transfer to an account designated in writing by Eagle Oil & Gas Co. Each Seller agrees that funds paid by Buyer into such account shall be deemed received proportionally by each of them. The foregoing payment direction is subject to the provisions of Section 10.04(i) authorizing direct payment to individual Sellers upon request.

Section 2.02 Deposit and Escrow Agreement. Concurrently with the execution of this Agreement by Buyer and Seller, Buyer shall deliver to Chase Bank, N.A., (the “Escrow Agent”), a performance guarantee deposit in the amount of five percent (5%) of the Base Price (the “Deposit”) pursuant to the terms of the Escrow Agreement substantially in the form attached hereto as Exhibit I (the “Escrow Agreement”). The Deposit shall be paid by Buyer to the Escrow Agent by means of a completed federal funds transfer to the account designated in the Escrow Agreement (the “Escrow Account”). In the event Closing occurs, the Deposit shall be reclassified to become the “Holdback Amount” and the Holdback Amount and the interest earned thereon shall be retained by the Escrow Agent until distributed as provided for herein. The Holdback Amount shall be held in the Escrow Account by way of security against all obligations of Seller with respect to Title Defects asserted prior to the end of the Post Closing Examination Period. If not done sooner, on February 1, 2012 (the “Title Defect Settlement Date”) the Parties shall jointly instruct the Escrow Agent to distribute to Buyer from the Escrow Account any amounts due as refunds for Title Defects. Concurrently, the Parties shall jointly instruct the Escrow Agent to release to Seller any monies remaining in the Escrow Account after paying to Buyer an amount equal to all sums due for Title Defects, unless, as of such date, there are unresolved Title Defects. To the extent there are unresolved Title Defects, the Escrow Agent shall retain the aggregate asserted value of unresolved Title Defects. As each Title Defect is resolved the Parties shall jointly instruct the Escrow Agent to distribute funds relating to such Title Defect to the Party and in the amount as directed by the Parties.

Section 2.03 Allocated Values. The Purchase Price is allocated among the Assets as set forth in Exhibit G attached hereto (the “Allocated Values”). Seller and Buyer agree that the Allocated Values shall be used to compute any adjustments to the Base Price pursuant to the provisions of Article III and Article IV.

Section 2.04 Effective Time. If the transactions contemplated hereby are consummated in accordance with the terms and provisions hereof, the ownership of the Assets shall be transferred from Seller to Buyer on the Closing Date, and effective as of 7:00 a.m. local time where the Assets are located on November 1, 2011 (the “Effective Time”).

Article III

(vii) all lessors’ royalties, overriding royalties, net profits interests, carried interests, production payments, reversionary interests and other burdens on or deductions from the proceeds of production created or in existence as of the Effective Time, whether recorded or unrecorded, provided that such matters do not operate to reduce the Net Revenue Interests of Seller below those set forth in Exhibit A or Exhibit A-1 or increase the Working Interests of Seller above those set forth in Exhibit A or Exhibit A-1 without a corresponding increase in the Net Revenue Interests;

(viii) required Third Party consents to assignment or similar agreements with respect to which (A) waivers or consents are obtained from the appropriate Parties for the transaction contemplated hereby, or (B) required notices have been given for the transaction contemplated hereby to the holders of such rights and the appropriate period for asserting such rights has expired without an exercise of such rights;

(ix) preferential rights to purchase and similar agreements with respect to which (A) waivers are obtained from the appropriate Parties for the transaction contemplated hereby, or (B) required notices have been given for the transaction contemplated hereby to the holders of such rights and the appropriate period for asserting such rights has expired without an exercise of such rights;

(x) all rights to consent by, required notices to, filings with, or other actions by Governmental Authorities in connection with the sale or conveyance of oil and gas leases or interests therein that are customarily obtained subsequent to such sale or conveyance;

(xi) rights reserved to or vested in any Governmental Authority to control or regulate any of the Assets and the applicable laws, rules, and regulations of such Governmental Authorities; and

(xii) Title Defects as to which there has been a reduction in the Purchase Price by the amount of the applicable Title Defect Value pursuant to Section 3.05(b), below, as to which the Title Defect Value has been refunded to Buyer after Closing pursuant to Section 3.05(c), below; or which have been waived.

Section 3.03 Title Defect. The term “Title Defect,” as used in this Agreement, shall mean:

(a) any encumbrance, encroachment, irregularity, defect in or objection to Seller’s ownership of any Asset that causes Seller not to have Defensible Title to such Asset;

(b) any default by Seller under a Lease, Contract, or document creating an Easement that would have a material adverse effect on the operation, value or use of such Asset.

(d) any written notice from any Governmental Authority or any other person that there are violations of any applicable laws, excluding, Environmental Laws in connection with the operation of the Assets;

(e) any gas imbalances as of the date set forth therein with respect to the Assets that is not listed on Schedule 12.02;

(f) any obligation by Seller by virtue of a take or pay payment, advance payment or other similar payment to deliver Hydrocarbons, or proceeds from the sale thereof, attributable to the Assets, at some future time without receiving payment therefor at or after the time of delivery;

(g) any oil or gas Well that has not been drilled and completed within the limits permitted by all applicable Leases, Contracts, pooling and unit agreements, and applicable laws;

(h) except as set forth on Schedule 3.07, any preferential purchase rights enabling any person to purchase or acquire any of the Assets or any interest therein or portion thereof as a result of or in connection with the execution or delivery of this Agreement or the consummation of the transactions contemplated by this Agreement, and of which waivers thereof are not obtained or the time for exercise has passed;

(i) except as set forth on Schedule 3.03(i), any consents required to be obtained in connection with the execution or delivery of this Agreement or the consummation of the transactions contemplated by this Agreement that have not been waived or obtained and as to which the time for exercise has not passed, other than consents by a Governmental Authority which are normally obtained after Closing;

(j) except as set forth on Schedule 3.03(j), the fact that an Asset is subject to any calls or production or other similar marketing restrictions on the sale or other disposition of Hydrocarbons produced from the Assets, but specifically not including dedications to product purchasers or gathering or transportation agreements;

(k) the absence from the Records of a document necessary to establish Defensible Title to an Asset does not, in itself, constitute a Title Defect; and

(l) no Permitted Encumbrance shall constitute a Title Defect.

Section 3.04 Notice of Title Defects.

(a) If Buyer discovers any Title Defect affecting any Asset, Buyer shall notify Seller as promptly as possible but no later than the expiration of the Post Closing Examination Period of such alleged Title Defect. To be effective, such notice must (i) be in writing, (ii) be received by Seller prior to the expiration of the Post Closing Examination Period, (iii) describe the Title Defect in sufficient, specific detail (including, without limitation, any alleged variance in the Net Revenue Interest or Working Interest), (iv) identify the specific Asset or Assets affected by such Title Defect (which shall include the entire Unit Acreage associated with the Well if the Title Defect affects a Well and the entire interest in lands covered by any Lease that is subject to a Title Defect), and (v) include the estimated value of such Title Defect as determined by Buyer. Any matters that would otherwise constitute Title Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, shall be deemed to have been waived by Buyer for all purposes and shall constitute Permitted Encumbrances.

(b) Upon the receipt of such effective notice from Buyer, Seller and Buyer shall attempt to agree on a resolution regarding the existence of the asserted Title Defect, the actions appropriate to cure the Title Defect, and the economic effect of the Title Defect on the related Assets.

(c) The value attributable to each Title Defect (the “Title Defect Value”) that is asserted by Buyer in the Title Defect notices shall be determined based upon the criteria set forth below:

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

(ii) If the Title Defect asserted is that the Net Revenue Interest attributable to any Well is less than that stated in Exhibit B or the Working Interest attributable to any Well is greater than that stated in Exhibit B, then the Title Defect Value shall take into account the relative change in the interest from Exhibit B and the appropriate Allocated Value attributed to such Asset.

(iii) If the Title Defect represents an obligation, encumbrance, burden or charge upon the affected Asset (including, without limitation, any increase in Working Interest for which there is not a proportionate increase in Net Revenue Interest) 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, the potential discounted economic effect of the Title Defect over the life of the affected Asset, and the Title Defect Values placed upon the Title Defect by Buyer and Seller.

(iv) If a Title Defect is not in effect or does not adversely affect an Asset throughout the entire productive life of such Asset, such fact shall be taken into account in determining the Title Defect Value.

(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 all the Assets affected thereby.

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

Section 3.05 Remedies for Title Defects.

(a) Seller shall use commercially reasonable efforts to cure Title Defects at its expense prior to the Title Defect Settlement Date, provided that Seller shall have no obligation to make any payments in connection with such efforts.

(b) With respect to each Title Defect that is asserted prior to the end of the Examination Period that is not cured on or before the Closing, except as otherwise provided in this Section 3.05, the Purchase Price shall be reduced by an amount equal to the Title Defect Value agreed upon in writing by Buyer and Seller. If the Title Defect Value equals or exceeds the Allocated Value of the affected Asset(s) then the affected Asset(s) shall not be conveyed to Buyer hereunder, in which event the Purchase Price shall be reduced only by the Allocated Value of the affected Asset(s). If the Title Defect affects a specific portion of or interest in the affected Asset then that portion of or interest in the affected Asset shall be excluded from the conveyance hereunder.

(c) With respect to each Title Defect that is asserted after Closing but prior to the end of the Post Closing Examination Period that is not cured on or before the Title Defect Settlement Date, except as otherwise provided in this Section 3.05, the Purchase Price shall be retroactively reduced by an amount equal to the Title Defect Value agreed upon in writing by Buyer and Seller. If the uncured Title Defect Value asserted after Closing equals or exceeds the Allocated Value of the affected Asset(s) then the affected Asset(s) shall be reconveyed to Buyer hereunder, in which event the Purchase Price shall be reduced retroactively by the Allocated Value of the affected Asset(s) and such reduction shall be reflected in the disposition of the Holdback Amount.

(d) If any Title Defect is in the nature of an unobtained consent to assignment or other restriction on assignability, the provisions of Section 3.08 shall apply.

(e) If on or before the Closing the Parties have not agreed upon the validity of any Title Defect asserted prior to the end of the Examination Period or have not agreed on the Title Defect Value attributable thereto, then, Seller shall have the right to remove the affected Asset from the sale and reduce the Purchase Price by the Allocated Value of that property and, in the absence of such an election by Seller, the validity of such Title Defect and/or such Title Defect Value shall be determined by an Independent Expert pursuant to Section 16.03. If the validity of any asserted Title Defect, or the Title Defect Value attributable thereto, is not determined before Closing, the Purchase Price paid at Closing shall not be reduced by virtue of such disputed Title Defect or Title Defect Value and the affected Asset shall be included in the conveyance to Buyer at Closing, and upon the final resolution of such dispute the Title Defect Value, if any, found to be attributable to such Title Defect shall, subject to this Section, be promptly refunded by Seller to Buyer and any appropriate reconveyance by Buyer to Seller shall be executed.

(f) If Closing occurs and Buyer asserts a Title Defect prior to the end of the Post Closing Examination Period, and the Parties have not agreed upon the validity of any Title Defect asserted prior to the Title Defect Settlement Date or have not agreed on the Title Defect Value attributable thereto, then, Seller shall have the right, to be exercised within ten (10) days of such date to remove the affected Asset from the sale and reduce the Purchase Price by the Allocated Value of that property and, in the absence of such an election by Seller, the validity of such Title Defect and/or such Title Defect Value shall be determined by an Independent Expert pursuant to Section 16.03. Upon such election by Seller, the Allocated Value of such affected Asset shall, subject to this Section 3.05, be promptly refunded by Seller to Buyer and Buyer shall reconvey the affected Asset to Seller on or before the Title Defect Settlement Date. Any such reconveyance shall be made with special warranty of title.

(g) Notwithstanding anything to the contrary in this Agreement, except with respect to Title Defects on non-proved acreage resulting from Seller owning fewer net acres covered by a particular Lease than set forth in Exhibit A or Exhibit A-1, (i) if the value of a given individual Title Defect does not exceed Seventy Five Thousand Dollars ($75,000.00), then no adjustment to the Base Price shall be made for such Title Defect, (ii) if the aggregate adjustment to the Base Price determined in accordance with this Agreement for combined Title Defects (exceeding Seventy Five Thousand Dollars ($75,000.00)) and Environmental Defects (exceeding Seventy-Five Thousand Dollars ($75,000.00)), does not exceed one and one half percent (1 1/2%) of the Base Price (the “Aggregate Deductible”) prior to any adjustments thereto, then no adjustment of the Base Price shall be made therefor, and (iii) if the aggregate adjustment to the Base Price determined in accordance with this Agreement for combined Title Defects (exceeding Seventy Five Thousand Dollars ($75,000.00)) and Environmental Defects (exceeding Seventy Five Thousand Dollars ($75,000.00)) and does exceed the Aggregate Deductible prior to any adjustments, then the Base Price shall only be adjusted by the amount of such excess. The Seventy Five Thousand Dollar ($75,000.00) threshold for Title Defects and the Aggregate Deductible shall apply collectively to Title Defects whether or not asserted before or after Closing pursuant to the terms hereof. For avoidance of doubt, the above described threshold of Seventy-Five Thousand Dollars is measured by the Title Defect Value of the combined interests of all Sellers in a property subject to a Title Defect (and not Seller-by-Seller) unless that defect affects only the interest of a single Seller, and the Aggregate Deductible shall be deemed met when all Title Defects and Environmental Defects exceed 1 ½% of the Base Price, regardless of the respective ownership of the Sellers in the properties subject to Title Defects or Environmental Defects. There shall be only one Aggregate Deductible applicable to all Title Defects regardless of when asserted. Neither the above described Seventy Five Thousand Dollars ($75,000.00) individual Title Defect threshold nor the Aggregate Deductible shall apply to Title Defects which are asserted due to Seller having Defensible Title to fewer non-proved net acres covered by a Lease than set forth on Exhibit A or Exhibit A-1.

Section 3.06 Special Warranty of Title. Each Seller hereby agrees to warrant and defend title to the Assets to the extent of the interests reflected as to each such Seller on Exhibits A, A-1 and B solely unto Buyer against every person whomsoever lawfully claiming or to claim the same or any part thereof, by, through or under Seller, but not otherwise; subject, however, to the Permitted Encumbrances and the other matters set forth herein. In no event shall the foregoing warranty extend to or be enforceable by any party other than Buyer, specifically excluding Buyer’s successors and assigns in all or part of the Assets.

Section 3.07 Preferential Rights to Purchase. Buyer’s good faith allocation of values as set forth in Exhibit G shall be used to prepare an allocation of the Purchase Price to Assets that are subject to preferential rights to purchase and will be set forth in Schedule 3.07.

Seller shall use its reasonable efforts to comply with all preferential right to purchase provisions relative to any Asset prior to the Closing. If, prior to Closing, a holder of a preferential purchase right notifies Seller that it intends to exercise its rights with respect to an Asset to which its preferential purchase right applies (as determined in accordance with the agreement in which the preferential purchase right arises) or the time for the exercise of such preferential right has not expired or the preferential right waived, the Asset covered by said preferential purchase right shall be excluded from the Assets to be conveyed to Buyer, and the Purchase Price shall be reduced by the value allocated to said Asset in Schedule 3.07. Buyer acknowledges and agrees that Seller shall determine (in its good faith judgment) the extent of the preferential purchase rights encumbering the Assets, and said determination shall be used by Seller to provide the preferential purchase right notifications. If the holder of the preferential purchase right fails to consummate the purchase of the Asset subject to the preferential purchase right, Seller shall promptly notify Buyer. Within ten (10) Business Days after Buyer’s receipt of such notice or Closing, whichever is later, Seller shall sell to Buyer, and Buyer shall purchase from Seller, such Asset under the terms of this Agreement for a price equal to the value allocated to such Asset in Schedule 3.07. Notwithstanding the foregoing, Buyer shall have no obligation under this Agreement or otherwise to purchase the Asset if Buyer is not notified of the preferential purchase right holder’s failure to consummate the purchase of the Asset within ninety (90) calendar days following Closing. Seller will use reasonable efforts to send out the applicable preferential right to purchase notices within five (5) Business Days after the date this Agreement is executed.

Section 3.08 Consents to Assignment. Seller shall use all reasonable efforts to obtain all necessary consents from Third Parties to assign the Assets prior to Closing (other than consents by a Governmental Authority which are normally obtained after Closing) and Buyer shall assist Seller with such efforts. To the extent such consents are asserted by Buyer as Title Defects but are not obtained prior to Closing, then such failure shall constitute a Title Defect as to that portion of the Assets affected thereby.

Section 3.09 Remedies for Title Benefits.

(a) If either Party discovers any Title Benefit during the Examination Period affecting the Assets, it shall promptly notify the other Party in writing thereof on or before the expiration of the Examination Period. Seller shall be entitled to an upward adjustment to the Purchase Price pursuant to Section 10.02(a)(i) with respect to all Title Benefits, in an amount mutually agreed upon by the Parties (the “Title Benefit Value”). For purposes of this Agreement, the term “Title Benefit” shall mean Seller’s interest in any Well shown on Exhibit B is greater than or in addition to that set forth in Exhibit B (including, without limitation, a Net Revenue Interest that is greater than that set forth in Exhibit B) or Seller’s Working Interest in any Well that is less than the Working Interest set forth in Exhibit B (without a corresponding decrease in the Net Revenue Interest). Such term shall also mean, as to each Lease, the net acres covered by such Lease and the Working and Net Revenue Interests of each Seller in any such lease are similarly greater than those set forth in Exhibit A or Exhibit A-1. Any matters that may otherwise constitute Title Benefits, but of which Buyer has not been specifically notified by Seller in accordance with the foregoing, shall be deemed to have been waived by Seller for all purposes.

(b) If on or before Closing the Parties have not agreed upon the validity of any asserted Title Benefit or have not agreed on the Title Benefit Value attributable thereto, then, Seller or Buyer shall have the right to remove the affected Asset from the sale and reduce the Purchase Price by the Allocated Value of the affected Asset and, in the absence of such an election, such Purchase Price adjustment shall be determined by an Independent Expert pursuant to Section 16.03. If Seller has asserted the existence of a Title Benefit and the amount of the Title Benefit Value has not been determined pursuant to this Agreement by the Closing, the undisputed portion of the Purchase Price with respect to the Asset affected by such Title Benefit shall be paid by Buyer at the Closing and, subject to Section 3.05, upon determination of the amount of such adjustment, any unpaid portion thereof shall be retained by Buyer or paid by Buyer to Seller, as the case may be.

Article IV

Environmental Matters

Section 4.01 Environmental Review.

(a) Buyer shall have the right to conduct or cause a consultant (“Buyer’s Environmental Consultant”) to conduct an environmental review of the Assets prior to the expiration of the Examination Period (“Buyer’s Environmental Review”). The cost and expense of Buyer’s Environmental Review, if any, shall be borne solely by Buyer. The scope of work comprising Buyer’s Environmental Review may include Phase I testing. More intrusive testing or procedures may not be conducted by Buyer without the prior consent of Seller. Provided, however, if Seller refuses any reasonable request by Buyer for more intrusive testing, Buyer may elect to have the affected Assets excluded from the transaction and the Purchase Price shall be reduced by the Allocated Value of the excluded Assets. Buyer shall (and shall cause Buyer’s Environmental Consultant to): (i) consult with Seller before conducting any work comprising Buyer’s Environmental Review, (ii) perform all such work in a safe and workmanlike manner and so as to not unreasonably interfere with Seller’s operations, and (iii) comply with all applicable laws, rules, and regulations. Seller shall be solely responsible for obtaining any Third Party consents that are required in order to perform any work comprising Buyer’s Environmental Review, and Seller shall consult with Buyer prior to requesting each such Third Party consent. Seller shall have the right to have a representative or representatives accompany Buyer and Buyer’s Environmental Consultant at all times during Buyer’s Environmental Review. If any required consent is not obtained, Buyer may elect to have the affected Assets to be excluded from the transaction and the Purchase Price shall be reduced by the Allocated Value of the Excluded 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 from and against all Claims, Losses, damages, costs, expenses, causes of action and judgments of any kind or character arising out of or relating to Buyer’s Environmental Review.

(b) Unless otherwise required by applicable law, Buyer shall (and shall cause Buyer’s Environmental Consultant to) treat confidentially any matters revealed by Buyer’s Environmental Review and any reports or data generated from such review (the “Environmental Information”), and Buyer shall not (and shall cause Buyer’s Environmental Consultant not to) disclose any Environmental Information to any Governmental Authority or other Third Party without the prior written consent of Seller. Unless otherwise required by law, Buyer may use the Environmental Information only in connection with the transactions contemplated by this Agreement. If Buyer, Buyer’s Environmental Consultant, or any Third Party to whom Buyer has provided any Environmental Information become legally compelled to disclose any of the Environmental Information, Buyer shall provide Seller with prompt notice sufficiently prior to any such disclosure so as to allow Seller to file any protective order, or seek any other remedy, as it deems appropriate under the circumstances. If this Agreement is terminated prior to the Closing, Buyer shall deliver the Environmental Information to Seller, which Environmental Information shall become the sole property of Seller. Buyer shall provide one set of copies of the Environmental Information to Seller without charge.

Section 4.02 Environmental Definitions.

(a) “Environmental Contaminants” means “hazardous substances” and “pollutants or contaminants”, as those terms are defined in Section 101 of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), “petroleum, including any fraction thereof,” and “natural gas, natural liquids, liquefied natural gas, or synthetic gas usable for fuel” as those terms are used in Section 101 of CERCLA, any “solid or hazardous waste” as those terms are defined or used in the Resource Conservation and Recovery Act, and any wastes regulated by applicable rules of the Railroad Commission of Texas. The term also includes naturally occurring radioactive material (NORM) concentrated, disposed of, released or present on, resulting from, or in association with Hydrocarbon activities.

(b) Environmental Defects. For purposes of this Agreement, the term “Environmental Defect” shall mean, with respect to any given Asset: (a) any event or condition (including, without limitation, any Release) with respect to air, land, soil, surface, subsurface strata, surface water, ground water, or sediment that causes the Assets to be currently subject to (or their owner or operator to have liability) any removal, remediation, or response action under, or not to be in compliance with, any Environmental Law or any authorization or permit issued by any Governmental Authority (a “Permit”) pursuant to any Environmental Law; (b) the existence of any written or oral Claim pending or threatened that reasonably may be expected to subject the Assets or the owner or the operator of the Assets to liability in favor of any Governmental Authority as the result of the alleged violation by such owner or operator or any other person of any Environmental Law as it pertains to the Assets or the existence of any event or condition on the Assets described in this definition; (c) the failure of the Assets to be in compliance, or the owner or operator of the Assets to comply, in each case in all material respects with all applicable Environmental Laws with respect to the Assets; (d) the failure of the owner or operator of the Assets to obtain or maintain in full force and effect any Permit required under applicable Environmental Laws with respect to the Assets; or (e) any event or condition described in the preceding clauses (a), (b), (c), and (d) that results, or could reasonably be expected to result, in liability to any Governmental Authority for any removal, remediation, or response action, or any other person for injury to or death of any person, persons, or other living thing, or damage, loss, or destruction of property located on the Assets. The term “Environmental Defect” includes, without limitation, any release, disposal, spilling, leaking, pouring, emission, emptying, discharge, injection, escape, transmission, leaching, or dumping (collectively, a “Release”), or any threatened Release, of any Environmental Contaminants from, or related in any way to the use, ownership, or operation of, the Assets that has not been remedied in accordance with all applicable Environmental Laws. Additionally, the term Environmental Defect includes the fact that a Well, other than the Monroe 39-2H Well, API # 42-389-32906, is, as of or after the Effective Time but before Closing, required by Texas Railroad Commission rule or order to be plugged or replugged by Seller.

(c) Environmental Laws. For purposes of this Agreement, the term “Environmental Laws” shall mean all laws, statutes, ordinances, court decisions, rules and regulations of any Governmental Authority pertaining to health or the environment as may be interpreted by applicable court decisions or administrative orders, including, without limitation, the Clean Air Act, as amended; CERCLA, as amended; the Federal Water Pollution Control Act, as amended; the Occupational Safety and Health Act, as amended; the Resources Conservation and Recovery Act, as amended; the Safe Drinking Water Act, as amended; the Toxic Substances Control Act, as amended; the Superfund Amendment and Reauthorization Act of 1986, as amended; the Hazardous Materials Transportation Act, as amended; The Oil Pollution Act of 1990, as amended; and comparable state and local laws.

(d) Environmental Defect Value. For purposes of this Agreement, the term “Environmental Defect Value” shall mean, with respect to any Environmental Defect, the value, as of the Closing Date, of the estimated costs and expenses to correct such Environmental Defect in the most cost-effective manner reasonably available, consistent with Environmental Laws, taking into account that non-permanent remedies (such as mechanisms to contain or stabilize hazardous materials, including, without limitation, monitoring site conditions, natural attenuation, risk-based corrective action, institutional controls or other appropriate restrictions on the use of property, caps, dikes, encapsulation, leachate collection systems, etc.) may be the most cost-effective manner reasonably available.

Section 4.03 Notice of Environmental Defects.

(a) If Buyer discovers any Environmental Defect affecting the Assets, Buyer shall notify Seller prior to the expiration of the Examination Period of such alleged Environmental Defect. To be effective, such notice must: (i) be in writing; (ii) be received by Seller prior to the expiration of the Examination Period; (iii) describe the Environmental Defect in specific detail; (iv) identify the specific Assets affected by such Environmental Defect; (v) identify the procedures recommended to correct the Environmental Defect, together with any related recommendations from Buyer’s Environmental Consultant, if available to Buyer; and (vi) state Buyer’s determination of the Environmental Defect Value, including, without limitation, the basis for such determination.

(b) Any matters that may otherwise constitute Environmental Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, together with any environmental matter that does not constitute an Environmental Defect, shall be deemed to have been waived by Buyer for all purposes and constitute an Assumed Obligation (as defined in Section 14.02). Upon the receipt of such effective notice from Buyer as to an Environmental Defect, Seller and Buyer shall attempt to agree to the existence of the asserted Environmental Defect, the actions appropriate to cure the Environmental Defect, and the amount of the Environmental Defect Value associated with such Environmental Defect.

Section 4.04 Remedies for Environmental Defects.

(a) Seller may use commercially reasonable efforts to cure Environmental Defects at its expense prior to Closing. Seller has no obligation hereunder to attempt to cure Environmental Defects.

(b) If at the time of Closing there is any uncured Environmental Defect as to which the Parties have agreed to an Environmental Defect Value then:

(i) if the Environmental Defect Value exceeds the Allocated Value of the affected Asset, either Party may elect to exclude the affected Asset from this transaction and the Base Price shall be adjusted downward by the amount of the Allocated Value of the affected Asset; and

(ii) if the Environmental Defect Value is less than or equal to the Allocated Value of the affected Asset, then Seller shall elect whether the affected Asset shall be included in this transaction and the Base Price shall be adjusted downward by the amount of the Environmental Defect Value or the affected Asset shall be removed from this sale and the Purchase Price adjusted downward by the amount of the Allocated Value of the affected Asset.

(c) If on or before three (3) Business Days before Closing the Parties have not agreed upon the validity of any asserted Environmental Defect or have not agreed on the Environmental Defect Value attributable thereto, then Seller shall have the right to remove the affected property from the sale and reduce the Purchase Price by the Allocated Value of that property and, in the absence of such an election by Seller, either Party shall have the right (exercised by giving written notice to the other Party at least one (1) Business Day before Closing) to elect to have the validity of such Environmental Defect and/or such Environmental Defect Value determined by an Independent Expert pursuant to Section 16.03. If the validity of any asserted Environmental Defect, or the Environmental Defect Value attributable thereto, is not determined before Closing and either Party has elected such determination, the Base Price paid at Closing shall not be reduced by virtue of such disputed Environmental Defect or Environmental Defect Value and the affected Asset shall be included in the conveyance to Buyer at Closing, and upon the final resolution of such dispute:

(i) If the Independent Expert determines that no Environmental Defect exists than no further action shall be taken; and

(ii) If the Independent Expert determines that an Environmental Defect exists and determines the Environmental Defect Value then the Parties shall have the options specified in Section 4.04(b), to be exercised within ten (10) Business Days of such determination, provided that Sellers shall make any payment (subject to the limitations provided in Section 4.04(e), below) and Buyer shall execute any reconveyance necessary to implement such result.

(d) If on or before Closing the Parties have not agreed upon the validity of any asserted Environmental Defect or have not agreed on the Environmental Defect Value attributable thereto and neither Party has elected determination by Independent Expert as provided above, then Sellers may, at their option, either elect to proceed with the Closing with the affected Assets included at their Allocated Value and with Seller indemnifying Buyer against the adverse affects of the asserted Environmental Defect, up to the amount of the Allocated Value, or, alternatively, Sellers may remove the affected Assets from this transaction and adjust the Base Price downward by the amount of the Allocated Value for such Assets.

(e) Notwithstanding anything to the contrary in this Agreement, (i) if the Environmental Defect Value for a given individual Environmental Defect does not exceed Seventy Five Thousand Dollars ($75,000.00), then no adjustment to the Base Price shall be made for such Environmental Defect; (ii) if the aggregate adjustment to the Base Price determined in accordance with this Agreement for combined Environmental Defects (exceeding Seventy Five Thousand Dollars ($75,000.00)) and Title Defects does not exceed the Aggregate Deductible prior to any adjustments thereto, then no adjustment of the Base Price shall be made therefore; and (iii) if the aggregate adjustment to the Base Price determined in accordance with this Agreement for Environmental Defects (exceeding Seventy Five Thousand Dollars ($75,000.00)) and Title Defects does exceed the Aggregate Deductible prior to any adjustments thereto, then the Base Price shall only be adjusted by the amount of such excess. For avoidance of doubt, the above described threshold of Seventy-Five Thousand Dollars is measured by the Environmental Defect Value of the combined interests of all Sellers in a property subject to an Environmental Defect (and not Seller-by-Seller), and the Aggregate Deductible shall be deemed met when all Title Defects and Environmental Defects exceed 1 ½% of the Base Price, regardless of the respective ownership of the Sellers in the properties subject to Title Defects or Environmental Defects.

Buyer shall have the right to determine the design and specifications for the well, provided that changes in design may require adjustments to the AFE. Seller will undertake to drill, complete, and equip such (replacement) well as a well capable of production in paying quantities. Upon the successful accomplishment of such operation Seller will execute a conveyance in substantially the form attached as Exhibit H to Buyer of the Leases insofar as they cover such unit and the well as so drilled and Buyer will pay to Seller the acreage value for such well as specified in Section 10.02(b)(iv) plus the actual costs incurred by Seller in drilling, completing, and equipping such well. Such assignment shall be effective upon completion of the described operations such that all production from the well shall be attributable to Buyer. Such assignment shall further provide that Seller shall retain all liability for and indemnify Buyer against Claims arising from its conduct of the operations contemplated by this Section. Such operation shall be conducted on the same basis as provided herein for other operations pursuant to this Section 13.02 despite the fact that it may not be commence until after Closing. Buyer’s obligation to buy such well and associated leasehold shall expire if Seller has not successfully drilled, completed, and equipped such well and tendered such conveyance prior to December 31, 2012. Seller shall not be obligated to sell such well and the associated leasehold to Buyer if the result of its doing so would be to impede its assertion of its claim against its insurer resulting from the blow-out of the previous well on such unit.

Seller shall operate the Assets from the Effective Time until Closing without compensation by Buyer (provided, however, that Eagle Oil and Gas Co., as operator under certain joint operating agreements shall be entitled to collect operating overhead charges with respect to the interests of the other working interest owners).

Section 13.02 Limitations on the Operational Obligations of Seller

(a) From and after the date of execution of this Agreement and until the Closing, and subject to the provisions of applicable operating and other agreements, Seller shall use its reasonable efforts to operate the Assets and use its reasonable efforts to cause any other operators to operate and administer the Assets in a manner consistent with its past practices, and shall carry on its business with respect to the Assets in substantially the same manner as before execution of this Agreement.

(b) Buyer acknowledges that each Party that is a Seller owns undivided interests in some or all of the Assets, and Buyer agrees that the acts or omissions of any one or more of the respective Sellers or the other working interest owners shall not constitute a violation of the provisions of this Article XIII by a Party Seller who is not itself in violation, nor shall any action required by a vote of working interest owners constitute such a violation so long as such a Party Seller has voted its interests in a manner that complies with the provisions of this Article XIII. To the extent that Seller is not the operator of any of the Assets, the obligations of Seller in this Article XIII shall be construed to require that Seller use reasonable efforts (without being obligated to incur any expense or institute any cause of action) to cause the operator of such Assets to take such actions or render such performance within the constraints of the applicable operating agreements and other applicable agreements.

(c) In no event shall Seller’s liability to Buyer regarding the operation of any of the Assets pursuant to this Article XIII exceed that of the operator to a non-operator under any joint operating agreement applicable to such Asset nor, absent any such applicable joint operating agreement, shall it extend to any failure in such regard by Seller other than its gross negligence or willful misconduct. In no event shall such liability exceed the Allocated Values of the affected Assets.

Section 13.03 Operation of the Assets After the Closing. It is expressly understood and agreed that Seller shall not be obligated to continue operating any of the Assets following the Closing and Buyer hereby assumes full responsibility for operating (or causing the operation of) all Assets following the Closing. Seller shall make its personnel available to Buyer prior to the Closing as may be reasonably necessary to assist in the transition if Buyer becomes the operator. Without implying any obligation on Seller’s part to continue operating any Assets after the Closing, if Seller elects to continue to operate any Assets following the Closing at the request of Buyer or any Third Party working interest owner, due to constraints of applicable joint operating agreement(s), failure of a successor operator to take over operations or other reasonable cause, such continued operation by Seller shall be for the account of Buyer, at the sole risk, cost and expense of Buyer. Buyer shall conduct or cause to be conducted all operations on the Assets after Closing in a good and workmanlike manner and in compliance with all applicable laws, rules, regulations and agreements. Notwithstanding anything to the contrary contained herein, within five (5) Business Days after Closing, Seller will transfer and assign to Buyer operating rights of the Assets under any applicable operating agreement, vote in favor of Buyer as operator of the Assets under any applicable operating agreement, and otherwise resign as operator of any wells within the Assets that Seller currently operates.

Section 13.04 Casualty Loss.

(a) Buyer shall assume all risk of loss with respect to, and any change in the condition of, the Assets from the Effective Time until the Closing, including, without limitation, with respect to the depletion of Hydrocarbons, the watering-out of any Well, the collapse of casing, sand infiltration of wells, and the depreciation of personal property.

(b) If after the Effective Time and prior to the Closing any part of the Assets shall be damaged or destroyed by fire or other casualty or if any part of the Assets shall be taken in condemnation or under the right of eminent domain or if proceedings for such purposes shall be pending or threatened, Seller shall provide written notice of such event to Buyer and this Agreement shall remain in full force and effect notwithstanding any such destruction, taking or proceeding, or the threat thereof and the Parties shall proceed with the transactions contemplated by this Agreement notwithstanding such destruction or taking without reduction of the Purchase Price, but subject to Section 13.04(c).

(c) Notwithstanding Section 13.04(a), in the event of any loss described in Section 13.04(b), at the Closing, Seller shall pay to Buyer all sums paid to Seller by Third Parties by reason of the destruction or taking of such Assets (up to the Allocated Value thereof), including, without limitation, any sums paid pursuant to any policy or agreement of insurance or indemnity, and shall assign, transfer and set over unto Buyer all of the rights, title and interest of Seller in and to any Claims, causes of action, unpaid proceeds or other payments from Third Parties, including, without limitation, any policy or agreement of insurance or indemnity, arising out of such destruction or taking (up to the Allocated Value thereof). Notwithstanding anything to the contrary in this Section 13.04, Seller shall not be obligated to carry or maintain, and shall have no obligation or liability to Buyer for its failure to carry or maintain, any insurance coverage with respect to any of the Assets. Notwithstanding anything to the contrary contained in this Section 13.04, should the uncompensated loss exceed fifteen percent (15%) of the Base Price, Buyer shall have the option to terminate this Agreement in which event Seller shall return the Deposit to Buyer within three (3) Business Days after such termination.

(d) The Parties recognize that prior to the Effective Time and during operations for the drilling and completion of the Monroe 39 #2H Well (API# 42-389-32906) a blowout occurred. Any insurance proceeds payable as a result of that occurrence shall be the property of Seller and any cause of action relating thereto and in favor of Seller shall remain the property of Seller.

Section 13.05 Operatorship. Within five (5) Business Days after Closing, Seller will send out notifications of its transfer or resignation as operator for all Wells Seller currently operates and is selling to Buyer pursuant to this Agreement. Seller makes no representation and/or warranty to Buyer as to the transferability or assignability of operatorship of such Wells. Buyer acknowledges that the rights and obligations associated with such wells are governed by applicable agreements and that operatorship will be determined by the terms of those agreements.

Article XIV

Obligations and Indemnification

Section 14.01 Retained Obligations. Provided that the Closing occurs, Seller shall retain (a) all obligations and liabilities of Seller for the payment or improper payment of royalties, rentals and other similar payments under the Leases relating to the Subject Interests accruing prior to the Effective Time; (b) 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, and (iii) other payment obligations that accrue and become due prior to the Effective Time; (c) all liability of Seller to Third Parties for personal injury or death to the extent occurring prior to the Effective Time as a result of the operation of the Assets; (d) ad valorem, property, severance and similar taxes attributable to the period of time prior to the Effective Time retained by Seller under Section 9.02; and (e) all litigation existing as of the Closing Date, to the extent it relates to the period of time prior to the Effective Time (collectively, the “Retained Obligations”). Specifically excluded from the Retained Obligations is any duty, obligation, or liability arising from or relating to any Environmental Defect or any Permitted Encumbrance except obligations agreed to be retained by Seller pursuant to Section 3.02(b)(ii) and (iii). Specifically included as a Retained Obligation is any Claim or obligation relating to the Monroe 39-2H Well, API # 42-389-32906. Except as to any matter that is the subject of a Claim for indemnification by Buyer delivered in accordance with Section 14.05, below, effective two (2) years after the Closing all Retained Obligations except for those described in Sections 14.01(c), (d) and (e) shall become Assumed Obligations. The Retained Obligations described in Sections 14.01(c), (d) and (e) and the Retained Obligation relating to the Monroe 39-2H Well shall never become Assumed Obligations and shall not be subject to any deductible applicable to Seller’s indemnity of Buyer.

Section 14.02 Assumed Obligations. Provided that the Closing occurs, Buyer hereby assumes all duties, obligations and liabilities of every kind and character with respect to the Assets or the ownership or operation thereof attributable to the period after the Effective Time, and all duties, obligations, and liabilities of every kind and character with respect to the Assets or the ownership or operation thereof attributable to the period before the Effective Time other than the Retained Obligations including, without limitation, those arising out of (a) the terms of the Easements, Contracts, Leases, Equipment, Intangible Rights, or Subject Interests comprising part of the Assets, (b) gas imbalances, subject to Section 12.02 above, (c) suspense accounts, (d) ad valorem, property, severance and other similar taxes or assessments based upon or measured by the ownership of the Assets or the production therefrom, (e) the condition of the Subject Interests, if such condition arose after the Effective Time, (f) obligations to properly plug and abandon or re-plug or re-abandon or remove Wells, flowlines, gathering lines or other facilities, Equipment or other personal property or fixtures comprising part of the Assets, (g) obligations to restore the surface of the Subject Interests and obligations to remediate or bring the Subject Interests into compliance with applicable Environmental Laws (including, without limitation, conducting any remediation activities that may be required on or otherwise in connection with activities on the Subject Interests), and (h) any other duty, obligation, event, condition or liability assumed by Buyer under the terms of this Agreement (collectively, the “Assumed Obligations”). Under the circumstances specified in Section 14.01, above, certain Retained Obligations shall become Assumed Obligations. All of the Assumed Obligations are assumed by Buyer REGARDLESS OF WHETHER CAUSED OR CONTRIBUTED TO BY THE ORDINARY NEGLIGENCE OR STRICT LIABILITY OF ANY SELLER, BUT EXCLUDING THE GROSS NEGLIGENCE AND WILLFUL MISCONDUCT OF ANY SELLER.

Section 14.03 Buyer’s Indemnification. If the Closing occurs then, regardless of any investigation made at any time by or on behalf of any Party or any information any Party may have and regardless of the presence or absence of insurance, Buyer shall release, defend, indemnify and hold harmless each Seller, its partners, affiliates, parents, and subsidiaries and its and their respective officers, directors, employees, agents, partners, representatives, members, managers, shareholders, affiliates, subsidiaries, successors and assigns (collectively, the “Seller Indemnitees”) from and against any and all Claims, damages, liabilities, losses, causes of action, costs and expenses (including, without limitation, those involving theories of negligence or strict liability and including, without limitation, fines, penalties, exemplary damages, court costs and attorneys’ fees and other litigation expenses) (collectively, the “Losses”) as a result of, arising out of, or related to the Assumed Obligations, REGARDLESS OF WHETHER CAUSED OR CONTRIBUTED TO BY THE SOLE, JOINT, COMPARATIVE, OR CONCURRENT NEGLIGENCE, OR STRICT LIABILITY OF ANY OF THE SELLER INDEMNITEES BUT EXCLUDING THE GROSS NEGLIGENCE AND WILLFUL MISCONDUCT OF ANY SELLER.

Section 14.04 Sellers’ Indemnification. If the Closing occurs, Sellers shall release, defend, indemnify and hold harmless Buyer, its partners, affiliates, parents, and subsidiaries and its and their respective officers, directors, employees, agents, partners, representatives, members, managers, shareholders, affiliates, subsidiaries, successors and assigns (collectively, the “Buyer Indemnitees”) from and against any and all Claims as a result of, arising out of, or related to the Retained Obligations. However, notwithstanding the generality of the foregoing, Sellers’ indemnification obligation under this Section 14.04 shall only apply if Buyer has provided Seller with written notice, conforming to the standards provided in Section 14.05, below, claiming indemnification as to such Claim within two (2) years of the Closing. Further, all of Sellers’ obligations hereunder to indemnify any Buyer Indemnitees shall be aggregated and Seller shall only be obligated to make payments regarding any such Claims when and to the extent that the aggregate amount of such Claims exceeds one and one half percent (1 1/2%) of the Purchase Price.

Section 14.05 Notices and Defense of Indemnified Matters. Each Seller Indemnitee or Buyer Indemnitee, as the case may be (an “Indemnified Party”), shall promptly notify the other Party (the “Indemnitor”) of any matter of which it becomes aware and for which it is entitled to indemnification from the Indemnitor under this Agreement. The notice shall include copies of any pleading or other written notice or demand received by the Indemnified Party. The Indemnitor shall be obligated to defend, at its sole expense, any litigation or other administrative or adversarial proceeding against the Indemnified Party relating to any matter for which the Indemnitor has agreed to indemnify and hold the Indemnified Party harmless under this Agreement. However, the Indemnified Party shall have the right to participate with the Indemnitor in the defense of any such matter at its own expense. No such Claim shall be compromised or settled by either the Indemnitor or the Indemnified Party, as applicable, in any manner that admits liability on the part of the other Party or that might otherwise adversely affect the interest of such other Party without the prior written consent of such other Party, which consent will not be unreasonably withheld or delayed. As a condition precedent to indemnification under this Agreement, the Indemnified Party shall assign to the Indemnitor, and the Indemnitor shall become subrogated to, all rights and Claims, up to the amount of indemnification, of the Indemnified Party against Third Parties arising out of or pertaining to the matters for which the Indemnitor shall provide indemnification. The amount of the Indemnified Party’s Claim for indemnification shall be reduced by the amount of any insurance reimbursement paid to the Indemnified Party pertaining to the Claim.
