Notwithstanding the foregoing, the Assets shall not include, and there is excepted, reserved and excluded from the sale contemplated hereby (collectively, the “Excluded Assets”): (a) all credits and refunds and all accounts, instruments and general intangibles (as such terms are defined in the Texas Uniform Commercial Code) attributable to the Assets to the extent attributable to any period of time prior to the Effective Time and that do not relate to obligations assumed by Purchaser pursuant to this Agreement; (b) all claims of Sellers for refunds of or loss carry forwards to the extent attributable to (i) ad valorem, severance, production or any other taxes attributable to any period prior to the Effective Time even if applied for after the Effective Time, (ii) income or franchise taxes, or (iii) any taxes attributable to the Excluded Assets, and such other refunds, and rights thereto, for amounts paid in connection with the Assets and attributable to the period prior to the Effective Time, including refunds of amounts paid under any gas gathering or transportation agreement, to the extent the same do not relate to obligations assumed by Purchaser pursuant to this Agreement; (c) all proceeds, income or revenues (and any security or other deposits made) to the extent attributable to (i) the Assets for any period prior to the Effective Time, if they do not relate to obligations assumed by Purchaser pursuant to this Agreement, or (ii) any Excluded Assets; (d) all of Sellers’ proprietary computer software, technology, patents, trade secrets, copyrights, names, trademarks, logos and other intellectual property; (e) subject to Section 9.2(d), all of Sellers’ rights and interests in geological and geophysical data which cannot be transferred without the consent of or payment to any third Person; (f) all documents and instruments of Sellers that may be protected by an attorney-client privilege unless such privileged documents and instruments pertain to litigation (including pending and threatened litigation) which Purchaser is assuming; (g) subject to Section 9.2(d), data and other information that cannot be disclosed or assigned to Purchaser as a result of confidentiality or similar arrangements under agreements with Persons who are not Affiliates of Sellers; (h) concurrent audit rights arising under any of the Material Agreements or otherwise with respect to any period prior to the Effective Time (unless relating to obligations assumed by Purchaser pursuant to this Agreement) or to any of the Excluded Assets; (i) all corporate, partnership and income tax records of Sellers; (j) copies of all Records (which shall be prepared at Sellers’ sole cost and expense); (k) personal property such as vehicles and certain equipment, supplies and office equipment, or any other items, in each case,

2.4 Effective Time.

(a) Subject to this Section 2.4, the purchase and sale of the Assets shall be effective as of December 28, 2012 at 11:59 p.m. Central Time (the “Effective Time”).

(b) Purchaser shall be entitled to all Hydrocarbon production from or attributable to the Leases, Units and Xxxxx at and after the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets at or after the Effective Time, including, without limitation, delay rentals, shut-in royalties, and lease bonuses, and shall be responsible for (and entitled to any refunds and indemnities with respect to) all Property Costs incurred at and after the Effective Time. Except as set forth to the contrary herein, Sellers shall be entitled to all Hydrocarbon production from or attributable to Leases, Units and Xxxxx prior to the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time, and shall be responsible for (and entitled to any refunds with respect to) all Property Costs incurred prior to the Effective Time. The terms “earned” and “incurred”, as used in this Agreement, shall be interpreted in accordance with generally accepted accounting principles and Counsel of Petroleum Accountants Societies standards. For purposes of this Section 2.4, determination of whether Property Costs are attributable to the period before or after the Effective Time shall be based on when services are rendered, when the goods are delivered, or when the work is performed. For clarification, the date an item or work is ordered is not the date of a pre-Effective Time transaction for settlement purposes, but rather the date on which the item ordered is delivered to the job site, or the date on which the work ordered is performed, shall be the relevant date. For purposes of allocating Hydrocarbon production (and accounts receivable with respect thereto including royalties and overriding royalties payable to the owner of the Assets), under this Section 2.4, (i) liquid Hydrocarbons shall be deemed to be “from or attributable to” the Leases, Units and Xxxxx when they pass through the pipeline connecting into the storage facilities into which they are run, or, if there is no such facility, the applicable LACT meters through which they are run, and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Leases, Units and Xxxxx when they pass through the delivery point sales meters on the pipelines through which they are transported. Sellers shall utilize reasonable interpolative procedures to arrive at an allocation of Hydrocarbon production when exact meter readings or gauging and strapping data is not available. Sellers shall provide to Purchaser, no later than three (3) Business Days prior to Closing, all data necessary to support any estimated allocation, for purposes of establishing the adjustment to the Purchase Price pursuant to Section 12.2 that will be used to determine the Closing settlement to be made pursuant to Section 12.2. Taxes shall be allocated and prorated in the manner set forth in Section 9.3. Right-of-way fees, insurance premiums and other Property Costs that are paid periodically shall be prorated based on the number of days in the applicable period falling before, and the number of days in the applicable period falling at or after, the Effective Time. In each case, Purchaser shall be responsible for the portion allocated to the period at and after the Effective

Time and Sellers shall be responsible for the portion allocated to the period before the Effective Time. After Closing, each Party shall be entitled to participate in all joint interest audits and other audits of Property Costs for which such Party is responsible or revenues to which such Party is entitled (whether entirely or in part) pursuant to this Section 2.4(b) or Section 12.2. All adjustments and payments made pursuant to this Section 2.4(b) and Section 12.2 shall be without duplication of any other amounts paid or received under this Agreement.

2.5 Maintenance of Records. Purchaser, or its successors or assigns, for a period of seven (7) years following Closing, will (a) retain the Records, (b) provide each Seller, its Affiliates, and its and their officers, employees and representatives with access to the Records during normal business hours for review and copying at such Seller’s sole cost and expense, and (c) provide such Seller, its Affiliates, and its and their officers, employees and representatives with access, during normal business hours, access, at such Seller’s sole cost, risk and expense, to materials received or produced after Closing relating to any Indemnity Claim made under Section 14.6 of this Agreement for review and copying.

ARTICLE 3

PURCHASE PRICE

3.1 Purchase Price. In consideration for the conveyance of the Assets to Purchaser, the Purchaser shall deliver to Sellers at Closing the Cash Consideration and evidence, reasonably satisfactory to Sellers, of the Assumption Consideration (collectively, the “Purchase Price”), adjusted in accordance with the terms of this Agreement.

3.2 Allocation of Purchase Price. On or before a date that is five (5) Business Days after the date hereof, Purchaser shall deliver to Sellers a proposed allocation of the unadjusted Purchase Price among the Assets, prepared in accordance with Section 1060 of the Internal Revenue Code of 1986, as amended, and the Treasury Regulations promulgated thereunder (and any similar provision of state or local law, as appropriate). Thereafter, prior to the Closing, the Parties shall reasonably cooperate to agree upon the final schedule setting forth such allocation (as finalized, the “Allocation Schedule”). If Purchaser and Sellers are unable to resolve any dispute as to the Allocation Schedule, such dispute shall be resolved promptly in the manner provided for disputes as to Purchase Price adjustments under Section 12.3(c). The “Allocated Value” for any Asset equals the portion of the unadjusted Purchase Price allocated to such Asset on the Allocation Schedule, as adjusted in the manner contemplated in Section 12.2. Any adjustments to the Purchase Price allocable to the Assets other than the adjustments provided for in Sections 5.5, 5.6 and 5.7 shall be applied on a pro-rata basis to the amounts set forth on the Allocation Schedule for all Assets. After all such adjustments are made, any adjustments to the Purchase Price pursuant to Sections 5.5, 5.6 and 5.7 shall be applied to the amounts set forth in the Allocation Schedule for the particular affected Assets. The Parties have accepted such Allocated Values (as adjusted in the manner contemplated above in this Section 3.2) for purposes of this Agreement and the transactions contemplated hereby, but otherwise make no representation or warranty as to the accuracy of such values. Sellers and Purchaser agree (a) that the Allocated Values shall be used by the Sellers and Purchaser as the basis for reporting asset values and other items for purposes of all federal, state, and local tax returns, including without limitation Internal Revenue Service Form 8594, and (b) that neither they nor their Affiliates will take positions inconsistent with the Allocated Values in notices to government authorities or in

audit or other proceedings with respect to taxes. Sellers and Purchaser further agree that the portion of Allocated Values included in the Allocation Schedule attributable to tangible personal property shall equal the fair value of such property on the Closing Date.

ARTICLE 4

THE PURCHASER’S INSPECTION

4.1 Access to Background Materials. Prior to Closing, and subject to Section 4.3, Sellers will make the Background Materials (as defined in Section 7.10) and the Records available to Purchaser and its representatives for inspection and review at Sellers’ offices during normal business hours to permit Purchaser to perform its due diligence review. Subject to the consent and cooperation of third Persons, Sellers will assist Purchaser in Purchaser’s efforts to obtain, at Purchaser’s expense, such additional information from such Persons as Purchaser may reasonably desire. Purchaser may inspect the Background Materials and such additional information only to the extent it may do so without violating any obligation of confidence or contractual commitment of Sellers to third Persons. If disclosure or access is prohibited, Sellers shall use commercially reasonable efforts to obtain permission to grant such access to Purchaser and its representatives, and shall provide Purchaser with as much information or access concerning the matter as is possible while still complying with applicable Laws and Sellers’ obligations; provided that Sellers shall not be required to make any payments for the benefit of any third Person in order to do so.

4.2 Disclaimer. Except for the representations and warranties contained in this Agreement, Sellers make no warranty or representation of any kind as to the Background Materials or any information contained therein. Purchaser agrees that any conclusions drawn from the Background Materials shall be the result of its own independent review and judgment.

4.3 Physical Access to the Leases and Xxxxx. During reasonable business hours, Sellers agree to grant Purchaser physical access to the Properties to allow Purchaser to conduct, at Purchaser’s sole risk and expense, on site inspections and environmental assessments of the Properties. In connection with any such on site inspections, Purchaser agrees not to unreasonably and materially interfere with the normal operation of the Properties and agrees to comply with all requirements of the operators of the Xxxxx. If Purchaser or its agents prepares an environmental assessment of any Lease or Well, Purchaser agrees to keep such assessment confidential, unless disclosure is required pursuant to applicable Law, and to furnish copies thereof to Sellers. IN CONNECTION WITH GRANTING SUCH ACCESS, PURCHASER REPRESENTS THAT IT IS ADEQUATELY INSURED AND WAIVES, RELEASES AND AGREES TO INDEMNIFY SELLERS, AND THEIR RESPECTIVE DIRECTORS, OFFICERS, MEMBERS, MANAGERS, LIMITED PARTNERS, SHAREHOLDERS, EMPLOYEES, AGENTS, REPRESENTATIVES AND AFFILIATES AGAINST ALL CLAIMS FOR INJURY TO, OR DEATH OF, PERSONS OR FOR DAMAGE TO PROPERTY ARISING IN ANY WAY FROM THE ACCESS AFFORDED TO PURCHASER HEREUNDER OR THE ACTIVITIES OF PURCHASER, REGARDLESS OF CAUSE, INCLUDING WITHOUT LIMITATION THE CONCURRENT NEGLIGENCE OF ANY SELLER AND ITS CONTRACTORS AND SUBCONTRACTORS AND THEIR EMPLOYEES, BUT EXCLUDING HOWEVER, THE GROSS NEGLIGENCE OR WILLFUL

MISCONDUCT OF ANY SUCH PERSON. THIS WAIVER, RELEASE AND INDEMNITY BY PURCHASER SHALL SURVIVE TERMINATION OF THIS AGREEMENT.

ARTICLE 5

TITLE MATTERS

5.1 Examination Period. Following the execution date of this Agreement until 5:00 p.m., local time in Houston, Texas on the date five (5) Business Days prior to the Closing Date (the “Examination Period”), Sellers shall permit Purchaser and its representatives to examine, at all reasonable times, in the offices of Sellers, in Houston, Texas, all abstracts of title, title opinions, title files, ownership maps, lease files, contract files, assignments, division orders, operating and accounting records and other records and agreements pertaining to the Assets insofar as same may now be in existence and in the possession of Sellers or their respective Affiliates, subject to such restrictions on disclosure as may exist under confidentiality agreements or other agreements binding on Sellers or such data; provided, however, that if disclosure or access is prohibited, Sellers shall use commercially reasonable efforts to obtain permission to grant such access to Purchaser and its representatives, and shall provide Purchaser with as much information or access concerning the matter as is possible while still complying with applicable Laws and Sellers’ obligations; provided that Sellers shall not be required to make any payments for the benefit of any third Person in order to do so.

5.2 Title Defect. The term “Title Defect,” as used in this Agreement, means: (a) any encumbrance, encroachment, irregularity, or defect in any Seller’s ownership of any Asset (expressly excluding Permitted Encumbrances) that causes Sellers (collectively) not to have Defensible Title to such Asset; or (b) any default by any Seller under a lease, farmout agreement or other contract or agreement that would (i) have a material adverse affect on the operation, value or use of such Asset, (ii) prevent any applicable Seller from receiving the proceeds of production attributable to such Seller’s interest therein; or (iii) result in cancellation of such Seller’s interest therein.

5.3 Notice of Title Defects. In order to make a claim for a Title Defect pursuant to this Article 5, Purchaser must notify Sellers of such Title Defect on or before the expiration of the Examination Period. To be effective, such notice must (a) be in writing, (b) include a description of the Title Defect, (c) identify the specific Asset or Assets affected by such Title Defect, (d) attach such supporting documentation as is in the possession of Purchaser, and (f) include the value of such Title Defect as determined by Purchaser; provided, however, an alleged failure to comply with subsections (a) through (f) shall not cause such notice to be invalid or any Title Defect to be waived in any respect if the defect notice is reasonably sufficient to provide notice to Sellers of the existence and general nature of the alleged Title Defect. Without limiting the representations and warranties of Sellers set forth in Article 7 (or the certificates to be delivered by Sellers at Closing pursuant to Section 12.4(e)), the special warranties of Sellers set forth in Section 5.5(e) and the Conveyance, or the indemnifications of Sellers in Article 14 with respect thereto, any matters that may otherwise constitute Title Defects, but of which Sellers have not been specifically notified by Purchaser in accordance with the foregoing, shall be deemed to have been waived by Purchaser.

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

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

(b) If the Title Defect asserted is that the Net Revenue Interest attributable to any Property is less than that stated in Exhibit B or the Working Interest attributable to any Well or Unit 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. If the Title Defect asserted is that the NRI attributable to any Property is less than the NRI set forth on Exhibit B, then the Title Defect Value is the product of the Allocated Value of the relevant Property, multiplied by a fraction, the numerator of which is the difference between such NRI set forth in Exhibit B and the actual NRI, and the denominator of which is such NRI set forth in Exhibit B.

(c) If the Title Defect represents an obligation, encumbrance, burden or charge upon the affected Asset (including any increase in WI for which there is not a proportionate increase in NRI) for which the economic detriment to Purchaser 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 Purchaser and Sellers, and such other facts as are necessary to make a proper evaluation.

(d) If a Title Defect 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.

(e) 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.

(f) Notwithstanding anything herein to the contrary, in no event shall a Title Defect Value exceed the Allocated Value of the Xxxxx or Units or other Assets affected thereby.

5.5 Remedies for Title Defects.

(a) Sellers and Purchaser shall attempt to agree on a resolution with respect to any Title Defect prior to Closing. Sellers may, at their collective option, attempt to cure such Title Defect at any time prior to Closing. If such Title Defect has not been cured at or prior to Closing (or the Parties cannot agree upon whether or to what extent the Title Defect has been so cured), the applicable Asset shall be conveyed at Closing, subject to all uncured Title Defects, and the Purchase Price shall be reduced by Purchaser’s estimate of the Title Defect Value attributable to each applicable Title Defect, subject, however, to Section 5.5(d), and Sellers shall have the right to elect to have the unresolved matter resolved by an independent expert pursuant to Section 5.10.

(b) If any Title Defect is in the nature of (i) an unobtained consent to assignment which causes the assignment to be null or void, or (ii) a restriction on assignability, in each case, subject to Section 9.2(d), the affected Asset shall be excluded from the assignment at Closing and the Purchase Price shall be reduced by the Allocated Value attributable to such Asset.

(c) If on or before Closing the Parties have not agreed upon the validity of any asserted Title Defect or have not agreed on the Title Defect Value attributable thereto, either Party shall have the right to elect to have the validity of such Title Defect or such Title Defect Value determined by an independent expert pursuant to Section 5.10.

(d) Notwithstanding anything to the contrary in this Agreement, (i) if the value of a given individual Title Defect does not exceed $20,000, then no adjustment to the Purchase Price shall be made for such Title Defect, (ii) if the aggregate adjustment to the Purchase Price determined in accordance with this Agreement for Title Defects (exceeding $20,000) less Title Benefits (exceeding $20,000) plus Casualty Loss and plus Environmental Defect Amounts (exceeding $20,000) does not exceed two per cent (2%) of the Purchase Price prior to any adjustments thereto, then no adjustment of the Purchase Price shall be made therefor, and (iii) if the aggregate adjustment to the Purchase Price determined in accordance with this Agreement for Title Defects (exceeding $20,000) less Title Benefits (exceeding $20,000) plus Casualty Loss and plus Environmental Defect Amounts (exceeding $20,000) does exceed two per cent (2%) of the Purchase Price prior to any adjustments thereto, then the Purchase Price shall only be adjusted by the amount of such excess.

(e) Sellers hereby agree to warrant and defend title to the Assets (and provide such warranty in the conveyance of the Assets provided to Purchaser at Closing) unto Purchaser, its successors and assigns, against every person whomsoever lawfully claiming or to claim the same or any part thereof, by, through or under Sellers, but not otherwise; subject, however, to the Permitted Encumbrances and the other matters set forth herein. Each Seller hereby assigns to Purchaser all rights, claims, and causes of action on title covenants and warranties given or made by such Seller’s predecessors (other than Affiliates of such Seller), and Purchaser is specifically subrogated to all rights which such Seller may have against its predecessors (other than Affiliates of such Seller), to the extent that such Seller may legally transfer such rights and grant such subrogation. Claims by Purchaser under the special warranty of title shall not be subject to the thresholds or deductibles set forth in Section 5.5(d) and shall not be deemed to constitute Assumed Obligations.

5.6 Remedies for Title Benefits.

(a) If Sellers discover any Title Benefit during the Examination Period affecting the Assets, Sellers may notify the other Party in writing thereof on or before the expiration of the Examination Period. Such notice shall be similar to the notice of Title Defects to be provided by Purchaser pursuant to Section 5.3, mutatis mutandis. Subject to Section 5.5, Sellers shall be entitled to an upward adjustment to the Purchase Price pursuant to Section 12.2 with respect to all Title Benefits, in an amount agreed upon by the Parties; provided, however, that if the aggregate upward adjustment to the Purchase Price determined in accordance with Section 5.5(d) does not exceed two percent (2%) of the Purchase Price prior to any adjustments

thereto, then no adjustment to the Purchase Price shall be made for Title Benefits, and, if the aggregate upward adjustment to the Purchase Price determined in accordance with Section 5.5(d) does exceed two percent (2%) of the Purchase Price prior to any adjustments thereto, then the Purchase Price shall only be adjusted upward by the amount of such excess. For purposes of this Agreement, the term “Title Benefit” means Sellers’ interest in any Property listed on Exhibit B that is greater than or in addition to that set forth in Exhibit B (including, without limitation, an NRI that is greater than that set forth in Exhibit B) or Sellers’ WI in any Asset that is less than the WI set forth in Exhibit B (without a corresponding decrease in the NRI). Any matters that may otherwise constitute Title Benefits, but of which Purchaser has not been specifically notified by Sellers in accordance with the foregoing, shall be deemed to have been waived by Sellers for all purposes.

(b) The value of a Title Benefit shall be determined by taking into account the Allocated Value of the affected Asset, the portion of the Asset affected by the Title Benefit, the legal effect of the Title Benefit, the potential discounted economic effect of the Title Benefit over the life of the affected Asset, the values placed upon the Title Benefit by Purchaser and Sellers, whether and to what extent the applicable instruments giving rise to the Title Benefit are filed in the records of any applicable Governmental Authority and would constitute notice to third Persons of the existence thereof under applicable Law, and such other facts as are necessary to make a proper evaluation. If a Title Benefit does not benefit an Asset throughout the entire productive life of such Asset, such fact shall be taken into account in determining the value of the Title Benefit. The value of a Title Benefit shall be determined without duplication of any amounts included in the value of another Title Benefit.

(c) Sellers and Purchaser shall attempt to agree on a resolution with respect to any Title Benefit prior to Closing. If the Parties cannot agree upon any Title Benefit, or the value thereof, prior to Closing, the applicable Asset shall be conveyed at Closing and the Purchase Price shall be increased by Purchaser’s estimate of the value, if any, attributable to each Title Benefit, subject, however, to Section 5.6(a), and either Party shall have the right to elect to have the validity of such Title Benefit or the value thereof determined by an independent expert pursuant to Section 5.10.

5.7 Casualty or Condemnation Loss.

(a) Subject to the further terms of this Agreement, including the representations and warranties of Sellers made in Article 7, and the certificate to be delivered by each Seller pursuant to Section 12.4(e), Purchaser shall assume all risk of loss with respect to, and any change in the condition of, the Assets from the Effective Time until Closing for production of Hydrocarbons through normal depletion (including, but not limited to, the watering out of any Well, collapsed casing or sand infiltration of any Well) and the depreciation of personal property due to ordinary wear and tear.

(b) Subject to the provisions of Sections 10.5 and 10.6, if, after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain (“Casualty Loss”), and the loss as a result of such Casualty Loss individually or in the aggregate exceeds two percent (2%) of the Purchase Price, Purchaser shall nevertheless be required to close, and Sellers shall

elect, by written notice to Purchaser prior to Closing, either (i) to cause the Assets affected by any Casualty Loss to be repaired or restored to at least their condition prior to such Casualty Loss, at Sellers’ sole cost, risk and expense, as promptly as reasonably practicable (which work may extend after the Closing Date), or (ii) to indemnify Purchaser in a manner reasonably acceptable to Purchaser against any costs, losses, or expenses that Purchaser reasonably incurs to repair the Assets subject to any Casualty Loss. In each case, Sellers shall retain all rights to insurance and other claims against third Persons with respect to the Casualty Loss, except to the extent the Parties otherwise agree in writing.

(c) If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets experiences a Casualty Loss, and the loss as a result of such Casualty Loss individually or in the aggregate is two percent (2%) or less of the Purchase Price, Purchaser shall nevertheless be required to close and Sellers shall, at Closing, pay to Purchaser all sums paid to Sellers by third Persons by reason of such Casualty Loss and shall assign, transfer and set over to Purchaser or subrogate Purchaser to all of Sellers’ right, title and interest (if any) in insurance claims, unpaid awards, and other rights against third Persons (other than Affiliates of any Seller, other than captive insurance Affiliates, and its and their directors, officers, employees and agents) arising out of the Casualty Loss.

5.8 Limitations on Applicability. The right of Purchaser to assert a Title Defect and the Sellers to assert Title Benefits under this Article 5 shall terminate as of the Examination Period; provided there shall be no termination of Purchaser’s or Sellers’ rights under Section 5.5 with respect to any bona fide Title Defect properly reported in a Title Defect notice or bona fide Title Benefit claim properly reported in a Title Benefit notice on or before the end of the Examination Period. Thereafter, except as to Sellers’ title representation in Section 5.5(e), and the further terms of this Agreement, including the representations and warranties of Sellers made in Article 7, and the certificate to be delivered by each Seller pursuant to Section 12.4(e) in respect thereof, Purchaser’s sole and exclusive rights and remedies with regard to title to the Assets shall be as set forth in, and arise under, the Conveyance transferring the Assets from Sellers to Purchaser.

5.9 Governmental Approvals Respecting Assets.

(a) Purchaser, within thirty (30) days after Closing, shall file for approval with the applicable Governmental Authorities all assignment documents, designation or change of operator documents and other state and federal transfer documents required to effectuate the transfer of the Assets and the operatorship thereof, where applicable. Purchaser and Sellers further agree promptly after Closing to take all other actions reasonably required of them by Governmental Authorities having jurisdiction to obtain all requisite regulatory approvals with respect to the transactions contemplated hereby, and to use reasonable commercial efforts to obtain the approval by such Governmental Authorities, of Sellers’ assignment documents requiring approval of such Governmental Authorities in order for Purchaser to be recognized by the federal or state agencies as the owner, or, where applicable operator of the Assets.

(b) Until all of the governmental approvals provided for in Section 5.9(a) have been obtained, the following shall occur with respect to the affected portion of the Assets:

(i) Sellers shall continue to hold record title to the affected Assets as nominee for Purchaser;

(ii) Purchaser shall be responsible for all Assumed Obligations with respect to the affected Leases and other affected portions of the Assets as if Purchaser was the record owner of such Assets as of the Effective Time; and

(iii) Sellers shall act as Purchaser’s nominee but shall be authorized to act only upon and in accordance with Purchaser’s written instructions, and Sellers shall have no authority, responsibility or discretion to perform any tasks or functions with respect to the Assets other than those which arise as a result of an emergency where the failure to act may result in injury or damage to Persons or Assets or are purely administrative or ministerial in nature, unless otherwise specifically requested and authorized by Purchaser.

(c) If a Governmental Authority fails to grant approval within twenty-four (24) months after Purchaser has filed for approval, Sellers may continue to hold record title to the affected Properties and other affected Assets as Purchaser’s nominee or, at Sellers’ sole option, they may terminate this Agreement and all of their obligations hereunder as to the affected Assets by giving sixty (60) days written notice to Purchaser. Upon such termination: (i) this Agreement shall be null and void and terminated only as to the affected Assets, (ii) Purchaser shall immediately re-convey and return to Sellers the conveyance documents and any and all other documents, materials and data previously delivered to Purchaser with respect to the Assets, and (iii) Sellers shall pay to Purchaser the Allocated Value of the affected Asset with adjustments thereto calculated in accordance with Section 12.2, without interest, attributable to the affected Assets from the Effective Time until such Assets are re-conveyed to Sellers.

5.10 Independent Expert. Sellers and Purchaser shall attempt to agree on all Title Defect Amounts and Title Benefit Amounts prior to Closing. If Sellers and Purchaser are unable to agree by Closing, Purchaser’s estimate shall control for the purposes of Closing pursuant to Section 12.3, and the Title Defect Values and the value of any Title Benefits in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 5.10. There shall be a single arbitrator, who shall be a title attorney with at least ten (10) years experience in oil and gas titles involving properties in the regional area in which the applicable Assets are located, as selected by mutual agreement of Sellers and Purchaser within two (2) Business Days after Closing, and absent such agreement, by the Houston office of the American Arbitration Association (the “Title Arbitrator”); provided, however, if the Parties have not agreed upon a Person to serve as Title Arbitrator within such two (2) Business Day period, and Sellers or Purchaser have not, within five (5) Business Days thereafter, formally applied to the Houston office of the American Arbitration Association to choose the Title Arbitrator, Sellers shall be deemed to have waived their dispute of any applicable Title Defect Values and the values of any Title Benefits. The arbitration proceeding shall be held in Xxxxxx County, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Title Arbitrator’s determination shall be made within fifteen (15) Business Days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the rules set forth in Sections 5.4, 5.5 and 5.6 and may consider such other matters as in the opinion of the Title

Arbitrator are necessary or helpful to make a proper determination. Additionally, the Title Arbitrator may consult with and engage disinterested third Persons to advise the arbitrator, including, without limitation, petroleum engineers. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect Values and Title Benefit values submitted by either Purchaser or Sellers and shall not be empowered to award damages, interest or penalties to any Party with respect to any matter. Sellers and Purchaser shall each bear its own legal fees and other costs of presenting its case and indemnify and hold harmless the other Parties with respect thereto. Sellers (collectively) and Purchaser (individually) shall each bear one-half of the costs and expenses of the Title Arbitrator, including any costs incurred by the Title Arbitrator that are attributable to such third Person consultation. Within ten (10) days after the Title Arbitrator delivers written notice to Sellers and Purchaser of his award with respect to a Title Defect Value or a Title Benefit value, (a) Purchaser shall pay to Sellers the amount, if any, so awarded by the Title Arbitrator to Sellers, and (b) Sellers shall pay to Purchaser the amount, if any, so awarded by the Title Arbitrator to Purchaser.

ARTICLE 6

ENVIRONMENTAL MATTERS

6.1 Assessment.

(a) Upon notice to Sellers and subject to Section 6.1(b), Purchaser shall, subject to the provisions of Section 6.6, have the right to conduct an environmental assessment of all or any portion of the Assets (the “Assessment”) to be conducted by a reputable environmental consulting or engineering firm (the “Environmental Consultant”). The Assessment shall be conducted at the sole cost and expense of Purchaser, and shall be subject to the indemnity provisions of Section 6.6. Prior to conducting any sampling, boring, drilling or other invasive investigative activity with respect to the Assets (“Invasive Activity”), Purchaser shall furnish for Sellers’ review a proposed scope of such Invasive Activity, including a description of the activities to be conducted and a description of the approximate locations of such activities. Sellers may, in their sole and absolute discretion, refuse to permit any Invasive Activity, in which event the affected Asset, at the option of Purchaser, shall be removed from the Assets and the Purchase Price reduced by the Allocated Value thereof. In addition, if any of the proposed activities may unreasonably interfere with normal operation of the Assets, Sellers may request a reasonable modification of the proposed Invasive Activity. Sellers shall have the right to be present during any Assessment of the Assets and shall have the right, at their option and expense, to split samples with Purchaser. After completing any Assessment of the Assets, Purchaser shall, at its sole cost and expense, restore the Assets to their condition prior to the commencement of such Assessment (unless Sellers request otherwise) and shall promptly and properly dispose of all drill cuttings, corings, or other investigative-derived wastes generated in the course of the Assessment. Purchaser shall maintain, and shall cause its officers, employees, representatives, consultants, agents and advisors to maintain, all information obtained by Purchaser pursuant to any Assessment or other due diligence activity as strictly confidential until the Closing occurs (or in perpetuity, in the event that Closing does not occur), unless disclosure of any facts as a result of such Assessment is required under any applicable Laws (including Environmental Laws or Laws requiring disclosure of reasons for the termination of this Agreement in the event that Closing does not occur). Purchaser shall provide Sellers with one copy of the final product of all environmental reports prepared by, or on behalf of, Purchaser

with respect to any Assessment or Invasive Activity conducted on the Assets. In the event that any necessary disclosures under applicable Environmental Laws are required with respect to matters discovered by any Assessment conducted by, for or on behalf of Purchaser, Purchaser agrees that Sellers shall be the responsible Parties for disclosing such matters to the appropriate Governmental Authorities.

(b) Purchaser acknowledges that the permission of the operator (if other than a Seller or its Affiliate) or another third Person may be required before Purchaser will be able to conduct an Assessment and that such permission may not be obtained. Sellers shall use reasonable efforts to obtain such permission for Purchaser. All inspections pursuant to this Section 6.1 shall be at Purchaser’s sole risk, cost, and expense. Purchaser agrees to comply with the rules, regulations and instructions issued by Sellers and other operators of the Assets regarding the actions of Purchaser while upon, entering, or leaving the Assets.

6.2 Notice of Environmental Defects. In order to make a claim for an Environmental Defect pursuant to this Article 6, Purchaser must notify Sellers of such Environmental Defect on or before the expiration of the Examination Period. To be effective, such claim must (a) be in writing, (b) include a description of the Environmental Defect in sufficient detail to allow Sellers to assess the existence, nature and economic significance of the Environmental Defect, (c) identify the specific Asset affected by such Environmental Defect, (d) attach such supporting documentation as is in the possession of Purchaser, and (e) include the value of such Environmental Defect as determined by Purchaser; provided, however, an alleged failure to comply with subsections (a) through (e) shall not cause such notice to be invalid or any Environmental Defect to be waived in any respect if the defect notice is reasonably sufficient to provide notice to Sellers of the existence and general nature of the alleged Environmental Defect. Without limiting the representations and warranties of Sellers set forth in Article 7 (or the certificates to be delivered by Sellers at Closing pursuant to Section 12.4) or the indemnifications of Sellers in Article 14 with respect thereto, any matters that may otherwise constitute Environmental Defects, but for which Purchaser has not asserted a claim in accordance with the foregoing, and which are specifically described in the report generated by the Environmental Consultant shall be deemed to have been waived by Purchaser.

6.3 Environmental Defect Value Determination. The value attributable to each Environmental Defect (the “Environmental Defect Value”) that is asserted by Purchaser in the Environmental Defect notices shall be determined based upon the criteria set forth below:

(a) If Purchaser and Sellers agree on the value of the Environmental Defect, that amount shall be the Environmental Defect Value.

(b) The Environmental Defect Value shall include the amount required to remove or remediate the Environmental Defect and otherwise rehabilitate or restore the affected Asset, such that it is in compliance with Environmental Laws, together with any fines, penalties, fees, damages, losses, or other amounts due, or alleged to be due, to a third Person with respect to the alleged Environmental Defect and the effect of any applicable limitation on the use or operation of the affected Asset due to the Environmental Defect imposed by a Governmental Authority or due to any remediation or other curative response.

(c) The Environmental Defect Amount with respect to an Environmental Defect shall be determined without duplication of any costs or losses included in another Environmental Defect Amount or adjustment to the Purchase Price.

6.4 Remedies for Environmental Defects.

(a) Sellers and Purchaser shall attempt to agree on a resolution with respect to any Environmental Defect prior to Closing. Sellers may, at their collective option (and at their sole cost, risk, and expense), attempt to cure such Environmental Defect at any time prior to Closing. For each claim asserted by Purchaser for an Environmental Defect, with respect to which the Parties cannot agree upon the Environmental Defect or the Environmental Defect Value (or whether or to what extent the Environmental Defect has been cured or remediated), at the sole option of Purchaser, (i) Sellers shall deliver to Purchaser a written indemnity agreement, in form and substance reasonable satisfactory to Purchaser, under which Sellers agree to fully, jointly and severally indemnify Purchaser from any and all losses, costs, expenses, claims and damages (including diminution in value) arising out of, or resulting from, such Environmental Defect (in which case there shall be no reduction in the Purchase Price), provided that such indemnification obligation shall be limited to the Allocated Value for the affect Asset, or (ii) the Purchase Price shall be reduced by the Environmental Defect Value with respect to each Environmental Defect (or, subject to Section 6.5, in the event that the Parties do not agree upon the existence of an Environmental Defect, or the Environmental Defect Value with respect thereto, Purchaser’s estimate of the Environmental Defect), provided that such reduction in the Purchase Price shall not exceed the Allocated Value for the affected Asset. Notwithstanding the foregoing, in the event that the aggregate of all Environmental Defects affecting an Asset exceeds the Allocated Value of such Asset, such Asset shall be removed from the transactions contemplated by this Agreement and the Purchase Price shall be reduced by the Allocated Value of the Assets, subject to Section 6.5.

(b) 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, either Party shall have the right to elect to have the validity of such Environmental Defect or such Environmental Defect Value determined by an independent expert pursuant to Section 6.5.

(c) Notwithstanding anything to the contrary in this Agreement, any adjustment to the Purchase Price for Environmental Defects shall be subject to Section 5.5(d).

(d) Without limitation of the rights of Purchaser pursuant to this Article 6, Purchaser acknowledges that the Assets have been used for exploration, development and production of Hydrocarbons and that there may be petroleum, produced water, wastes, or other substances or materials located in, on or under the Assets. Equipment and sites included in the Assets may contain asbestos, hazardous substances (as defined in applicable Environmental Laws) or naturally occurring radioactive materials (“NORM”). NORM may affix or attach itself to the inside of xxxxx, materials, and equipment as scale or in other forms. The xxxxx, materials and equipment located on the Assets may contain NORM and other wastes or hazardous substances. NORM containing material and/or other wastes or hazardous substances may have come in contact with various environmental media, including without limitation, water, soils or

sediment. Special procedures may be required for the assessment, remediation, removal, transportation or disposal of environmental media, wastes, asbestos, hazardous substances, and NORM from the Assets.

6.5 Independent Environmental Expert. Sellers and Purchaser shall attempt to agree on all Environmental Defect Values prior to Closing. If Sellers and Purchaser are unable to agree by Closing, unless the applicable Asset is excluded pursuant to Section 6.4(a), Purchaser’s estimate shall control for the purposes of Closing pursuant to Section 12.3, and the Environmental Defect Values in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 6.5. There shall be a single arbitrator, who shall be a reputable environmental consultant or engineer with at least ten (10) years experience in corrective environmental action regarding oil and gas properties in the state in which the Assets that are the subject of the dispute are located, as selected by agreement of Sellers and Purchaser within five (5) Business Days after Closing, and absent such agreement, by the Houston office of the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be held in Xxxxxx County, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Environmental Arbitrator’s determination shall be made within fifteen (15) Business Days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in Section 6.3 and may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. Additionally, the Environmental Arbitrator may consult with and engage disinterested third Persons to advise the arbitrator. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defect Values submitted by either Purchaser or Sellers and shall not be empowered to award damages, interest or penalties to any Party with respect to any matter. Sellers and Purchaser shall each bear their own legal fees and other costs of presenting their respective cases and indemnify and hold harmless the other Party with respect thereto. Sellers (collectively) and Purchaser (individually) shall each bear one-half of the costs and expenses of the Environmental Arbitrator, including any costs incurred by the Environmental Arbitrator that are attributable to such third Person consultation. Within ten (10) days after the Environmental Arbitrator delivers written notice to Sellers and Purchaser of his award with respect to an Environmental Defect Value and the aggregate of all Environmental Defect Values attributable to the affected Asset is less than the Allocated Value for the affected Asset, then Sellers shall convey the affected Assets to Purchaser, and Purchaser shall pay to Sellers the amount by which the Purchase Price was reduced with respect to such affected Assets at Closing, less the amount of any applicable Environmental Defect Values. If the Environmental Arbitrator delivers written notice to Sellers and Purchaser that his award with respect to an Environmental Defect exceeds the Allocated Value for such affected Asset, or the aggregate of all Environmental Defect Values affecting such Asset exceed the Allocated Value for such Asset, then the affected Asset shall be excluded from the contemplated transaction (and shall constitute an Excluded Asset) and neither Party shall have any liability to the other with respect to the Asset. With respect to any Asset affected by an Environmental Defect that was conveyed to Purchaser at Closing, within ten (10) days after the Environmental Arbitrator delivers written notice to Sellers and Purchaser of his award with respect to the applicable Environmental Defect Value, Purchaser shall pay to Sellers the

amount, if any so awarded by the Environmental Arbitrator to Sellers, and Sellers shall pay to Purchaser the amount, if any, so awarded by the Environmental Arbitrator to Purchaser.

6.6 Access Indemnity. THE PURCHASER HEREBY AGREES TO DEFEND, INDEMNIFY, RELEASE, PROTECT, SAVE AND HOLD HARMLESS SELLER INDEMNITEES FROM AND AGAINST ANY AND ALL LOSSES AND CLAIMS RESULTING FROM ANY DUE DILIGENCE ACTIVITY CONDUCTED BY THE PURCHASER OR ITS AGENTS, WHETHER BEFORE OR AFTER THE EXECUTION OF THIS AGREEMENT, INCLUDING, WITHOUT LIMITATION, ANY LOSSES RESULTING, IN WHOLE OR IN PART, FROM THE NEGLIGENCE OR STRICT LIABILITY OF SELLERS, BUT EXCLUDING THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

Purchaser’s representatives have visited, or, prior to Closing will visit, the offices of Sellers and have been given (or, prior to Closing will be given) opportunities to examine the Background Materials. Except as expressly provided in this Agreement, Sellers shall not have any liability to Purchaser or its affiliates, agents, representatives or employees resulting from any use, authorized or unauthorized, of the Background Materials or other information relating to the Assets provided by or on behalf of Sellers.

9.2 Covenants and Agreements of the Parties. The Parties covenant and agree with each other as follows:

(a) Confidentiality. All data and information, whether written or oral, obtained from Sellers in connection with the transactions contemplated hereby, including the Records and Background Materials, whether obtained by Purchaser before or after the execution of this Agreement, and data and information generated by Purchaser based on data or information obtained from Sellers in connection with the transactions contemplated hereby (collectively, the “Information”), is deemed by the Parties to be confidential. Until the Closing (and for a period of one year after December 28, 2012, if Closing should not occur for any reason), except as required by Law, Purchaser and its officers, agents and representatives will hold in strict confidence the terms of this Agreement, and all Information, except any Information which: (i) at the time of disclosure to Purchaser by Sellers is in the public domain; (ii) after disclosure to Purchaser by Sellers becomes part of the public domain by publication or otherwise, except by breach of this commitment by Purchaser; (iii) Purchaser can establish was rightfully in Purchaser’s possession at the time of disclosure to Purchaser by Sellers; (iv) Purchaser rightfully received from third Persons free of any obligation of confidence; (v) is developed independently by Purchaser without the Information, provided that the Person or Persons developing the data shall not have had access to the Information; or (vi) the disclosure of which is reasonably necessary in order to comply with applicable Transfer Requirements or Preferential Rights, notices required to be given under applicable contracts or to seek approvals and consents of Governmental Authorities for the conveyance of any Assets or the transactions contemplated hereby.

(b) Return of Information. If Closing does not occur and this Agreement is terminated, if Sellers so request at any time, Purchaser shall: (i) return to Sellers all copies of the Information in possession of Purchaser obtained pursuant to any provision of this Agreement, which Information is at the time of termination required to be held in confidence pursuant to this Section 9.2; and (ii) destroy any and all notes, reports, studies or analyses based on, or

incorporating, the Information. The terms of Section 9.2 shall survive termination of this Agreement.

(c) Injunctive Relief. Purchaser agrees that Sellers will not have an adequate remedy at law if Purchaser violates any of the terms of Sections 9.2(a) and (b). In such event, Sellers will have the right, in addition to any other it may have, to obtain injunctive relief to restrain any breach or threatened breach of the terms of Sections 9.2(a) and/or (b), or to obtain specific enforcement of such terms.

(d) Preferential Purchase Rights and Transfer Requirements.

(i) Purchaser’s purchase of the Assets is expressly subject to all validly existing and applicable Preferential Rights and Transfer Requirements. Promptly after the date hereof, Sellers shall prepare and send notices to holders of any Preferential Rights and Transfer Restrictions (which notices shall be in form and substance reasonably satisfactory to Purchaser), and otherwise initiate all procedures which in Sellers’ good faith judgment are reasonably required to comply with or obtain the waiver of all Preferential Rights and Transfer Requirements with respect to the transactions contemplated by this Agreement. Sellers shall not be obligated to pay any consideration to (or incur any cost or expense for the benefit of) the holder of any Preferential Right or Transfer Requirement in order to obtain the waiver thereof or compliance therewith.

(ii) Any Preferential Right must be exercised subject to all terms and conditions set forth in this Agreement, including the successful Closing of this Agreement pursuant to Article 12. The portion of the Purchase Price to be allocated to any Asset or portion thereof affected by a Preferential Right (a “Preferential Asset”) or that becomes a Retained Asset shall be the Allocated Value for such Asset. If a Preferential Asset or a Retained Asset affects only a portion of an Asset and a portion of the Purchase Price has not been allocated specifically to such portion of an Asset on the Allocation Schedule, then the portion of the Purchase Price to be allocated to such Preferential Asset or Retained Asset shall be determined in a reasonable manner taking into account the net acreage (or net acre feet, as appropriate) that the portion of such Asset affected by such Preferential Asset or Retained Asset bears to the net acreage (or net acre feet, as appropriate) in the entire Asset.

(iii) If the holder of a Preferential Right who has been offered a Preferential Asset pursuant to Section 9.2(d)(i) elects prior to Closing to purchase such Preferential Asset in accordance with the terms of such Preferential Right, and Seller and Purchaser receive written notice of such election prior to the Closing, such Preferential Asset will be eliminated from the Assets and the Purchase Price shall be reduced by the portion of the Purchase Price allocated to such Preferential Asset pursuant to Section 9.2(d)(ii).

(iv) In the event:

(A) a third Person brings any suit, action or other proceeding prior to the Closing seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated hereby in connection with a claim to enforce a Preferential Right;

(B) a third Person fails to exercise or waive its Preferential Right prior to Closing, and the time for the exercise or waiver thereof pursuant to the terms of the instrument creating such Preferential Right has not expired; or

(C) an Asset is subject to a Transfer Requirement that has not been expressly waived or otherwise satisfied prior to the Closing Date,

then, unless otherwise agreed by Sellers and Purchaser, the Asset or portion thereof affected by such Preferential Right or Transfer Requirement (a “Retained Asset”) shall be held back from the Assets to be transferred and conveyed to Purchaser at Closing and the Purchase Price to be paid at Closing shall be reduced by the portion of the Purchase Price which is allocated to such Retained Asset pursuant to Section 9.2(d)(ii); provided, however, that, in the event that a Retained Asset is an Asset other than a Property, and Purchaser is assigned the Property or Properties to which such Asset relates, but such Asset is not transferred to Purchaser due to the unwaived Transfer Requirement, Purchaser and Seller shall continue after Closing to use commercially reasonable efforts to obtain the waiver or consent required under the Transfer Requirement so that such Asset may be transferred to Purchaser upon receipt of such consent and waiver, and, if permitted pursuant to applicable Law and agreement, Sections 5.9(b) and 5.9(c) shall apply with respect to such Asset as though such Asset was subject to unobtained governmental approvals.

(v) Any Retained Asset so held back at the initial Closing will be conveyed to Purchaser at a delayed Closing (which shall become the new Closing Date with respect to such Retained Asset), within ten (10) days following the date on which the Transfer Requirement has been satisfied, the time for exercising the Preferential Right has expired (without exercise or any action, or threat of action, to enforce such Preferential Right) or the suit, action or other proceeding, if any, referenced in clause (iv)(A) above is settled or a judgment is rendered (and no longer subject to appeal) permitting transfer of the Retained Asset to Purchaser pursuant to this Agreement, and Sellers obtain a waiver of or notice of election not to exercise or otherwise satisfy all remaining Preferential Rights and Transfer Requirements with respect to such Retained Asset as contemplated by this Section. At the delayed Closing, Purchaser shall pay Sellers a purchase price equal to the amount by which the Purchase Price was reduced on account of the holding back of such Retained Asset (as adjusted pursuant to Article 3 through the new Closing Date therefor); provided, however, if all such Preference Rights and Transfer Requirements with respect to any Retained Asset so held back at the initial Closing are not obtained, complied with, waived or otherwise satisfied as contemplated by this Section within one hundred eighty (180) days after the initial Closing has occurred with respect to any Assets, then such Retained Asset shall be eliminated from the Assets and this Agreement unless Purchaser elects to proceed with a closing on such Retained Asset, in which case Purchaser shall be deemed to have waived any objection and shall be obligated to indemnify the Seller Indemnitees for all claims, losses and damages with respect to non-compliance with such Preferential Rights and Transfer Requirements related to such Retained Asset.

(e) Sellers acknowledge that the Purchaser and its Affiliates may be required to include statements of revenues and direct operating expenses and other financial information relating to the Assets (“Financial Statements”) in documents filed with the Securities and Exchange Commission (the “SEC”) by the Purchaser and its Affiliates pursuant to the Securities

Act of 1933, as amended (the “Securities Act”), and that such Financial Statements may be required to be audited. In that regard, Sellers shall provide the Purchaser and its Affiliates reasonable access to such records (to the extent such information is available) and personnel of Sellers as the Purchaser and its Affiliates may reasonably request to enable the Purchaser and its Affiliates, and their representatives and accountants, at the Purchaser’s or its Affiliates’ sole cost and expense, to create and audit any Financial Statements that the Purchaser and its Affiliates deem necessary. Sellers shall consent to the inclusion or incorporation by reference of the Financial Statements in any registration statement, report or other document of Purchaser or its Affiliates to be filed with the SEC in which Purchaser or such applicable Affiliate reasonably determines that the Financial Statements are required to be included or incorporated by reference to satisfy any rule or regulation of the SEC or to satisfy relevant disclosure obligations under the Securities Act or the Securities Exchange Act of 1934, as amended. Upon request of the Purchaser or its Affiliates, Sellers shall request the external audit firm that audits the Financial Statements to consent to the inclusion or incorporation by reference of its audit opinion with respect to the audited Financial Statements in any such registration statement, report or other document. Sellers shall provide the Purchaser and its Affiliates and their independent accountants with access to (i) any audit work papers of Sellers’ independent accountants and (ii) any management representation letters provided by Sellers to Sellers’ independent accountants.

9.3 Tax Matters.

(a) Apportionment of Tax Liability. All Taxes based on or measured by production, purchase or sale of Hydrocarbons shall be deemed attributable to the period during which such production occurred and not attributable to the year in which such Taxes are assessed. Sellers shall be responsible for, and shall bear and pay, such Taxes attributable to the period prior to the Effective Time, and Purchaser shall be responsible for, and shall bear and pay, such Taxes for any period that begins at or after the Effective Time. All property, ad valorem and similar Taxes with respect to the tax period in which the Effective Time occurs shall be apportioned as of the Effective Time between the Sellers and Purchaser, with such Taxes being allocated pro rata per day between the period prior to the Effective Time and the period that begins at or after the Effective Time. Sellers shall be responsible for, and shall bear and pay, such Taxes attributable to the period prior to the Effective Time, and Purchaser shall be responsible for, and shall bear and pay, such Taxes for any period that begins at or after the Effective Time. The apportionment of Taxes between the Parties shall take place as an adjustment to the Purchase Price pursuant to Section 12.2 in the Statement for Taxes for which information is available at the Closing Date and in the final statement prepared pursuant to Section 12.3(b) for all remaining Taxes, using estimates of such Taxes if actual numbers are not available.

(b) Tax Reports and Returns. Sellers agree to file all Tax returns for the period of time prior to the Effective Time, and Purchaser agrees to file all Tax returns for the period of time at or after the Effective Time. Purchaser and Sellers agree to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information and assistance relating to the Assets, including, without limitation, access to books and records, as is reasonably necessary for the filing of all Tax returns by Purchaser or Sellers, the making of any election relating to Taxes, the preparation for any audit by any Taxing authority and the

prosecution or defense of any claim, suit or proceeding relating to any Tax. Purchaser agrees to file all Tax returns and reports applicable to the Assets that are required to be filed after the Closing Date, and pay all required Taxes payable with respect to the Assets subject to the provisions of Section 9.3(a). Purchaser and Sellers shall cooperate fully with each other in the conduct of any audit, litigation or other proceeding relating to taxes involving the Assets or the allocation discussed in Section 3.2.

(c) Transfer Taxes. The Purchaser shall be responsible for and pay all sales, transfer, use and similar Taxes arising from or associated with the transfer of the Assets (other than Taxes based on income) and all costs and expenses (including recording fees and real estate transfer taxes and real estate transfer stamps) incurred in connection with obtaining or recording title to the Assets.

13.3 Termination Damages.

(a) If all conditions precedent to the obligations of Purchaser set forth in Article 11 have been met and the transactions contemplated by this Agreement are not consummated on or before the Closing Date because of the negligent or willful failure of Purchaser to perform any of its obligations hereunder in any material respect, or the material breach of any representation or warranty herein by Purchaser, then in such event, Sellers shall have the option to terminate this Agreement, in which case Sellers may pursue all available legal and equitable remedies.

(b) If all conditions precedent to the obligations of Sellers set forth in Article 10 have been met and the transactions contemplated by this Agreement are not consummated on or before the Closing Date because of the negligent or willful failure of any Seller to perform any of its obligations hereunder in any material respect, or the breach of any representation or warranty herein by any Seller, then in such event, Purchaser shall have the option to terminate this Agreement, in which case Purchaser may pursue all available legal and equitable remedies.

(c) Notwithstanding anything to the contrary in this Agreement, in no event shall any Party be entitled to receive any punitive, indirect or consequential damages unless same are a part of a third Person claim for which a Party is seeking indemnification hereunder, REGARDLESS OF WHETHER CAUSED OR CONTRIBUTED TO BY THE SOLE, JOINT, COMPARATIVE OR CONCURRENT NEGLIGENCE OR STRICT LIABILITY OF THE OTHER PARTY, BUT EXPRESSLY EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

ARTICLE 14

OBLIGATIONS AND INDEMNIFICATION

14.1 Retained Obligations. Provided that the Closing occurs, (a) Sellers shall retain all obligations and liabilities related to (i) the Excluded Assets, (ii) Property Costs and other costs which are for the account of Sellers pursuant to Section 2.4(b) or Section 12.2, (iii) ad valorem, property, and similar Taxes attributable to periods of time prior to the Effective Time and Sellers’ income, gross receipts, profits, capital, capital gains or similar taxes (including

Seller and Purchaser agree that suspense funds contained in suspense accounts (the “Suspense Interests”) as well as any and all responsibility, liability and/or obligations with respect thereto will be retained by Seller, and Seller shall continue to disburse and/or escheat such Suspense Interests as required by contract or statute.

14.2 Assumed Obligations. Provided that the Closing occurs, Purchaser hereby assumes all duties, obligations and liabilities of every kind and character with respect to the Assets or the ownership, operation, condition or use thereof, whether attributable to periods before or after the Effective Time, including, without limitation, those arising out of (a) the terms of the Material Agreements, Leases, or Assets or any other interests, contracts or obligations comprising part of or directly related to the ownership or operation of the Assets, (b) ad valorem, property, severance, production and other similar taxes or assessments based upon or measured by the ownership of the Assets or the production therefrom attributable to any period on or after the Effective Time, and the Taxes allocated to Purchaser pursuant to Section 9.3(c), (c) the condition (including environmental condition, subject to the remedies provided in Article 6) of the Assets, (d) obligations to properly plug and abandon or re-plug or re-abandon or remove xxxxx, flowlines, gathering lines or other facilities, equipment or other personal property or fixtures comprising part of the Assets, (e) subject to the remedies provided in Article 6, obligations to restore the surface of the 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 any other duty, obligation, event, condition or liability assumed by Purchaser under the terms of this Agreement and (f) Sellers’ obligations to retain and manage, either through suspense or escrow accounts a portion of the Gross Proceeds, as defined in the LL&E ORRI Conveyance attributable to the interest of

LL&E Royalty Trust (the “Trust”) pursuant to that certain Conveyance of Overriding Royalty Interest (the “LL&E ORRI Conveyance”) from the Louisiana Land and Exploration Company to the Trust dated June 28, 1983 (the “LL&E Excess Production Cost Obligation”) (collectively, the “Assumed Obligations”).

14.3 Purchaser’s Indemnification. Provided that the Closing occurs, Purchaser shall release, defend, indemnify and hold harmless each Seller, its partners and affiliates, and their respective officers, directors, managers, employees, agents, partners, representatives, members, 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 court costs and attorneys’ fees) (collectively, the “Losses”) as a result of, arising out of, or related to, (a) the Assumed Obligations, (b) Purchaser’s breach of any of its covenants or agreements contained in Section 9.2, or (c) the breach of any representation or warranty made by Purchaser in Article 8, REGARDLESS OF WHETHER CAUSED OR CONTRIBUTED TO BY THE JOINT, COMPARATIVE OR CONCURRENT NEGLIGENCE OR STRICT LIABILITY OF ANY OF THE SELLER INDEMNITEES, BUT EXPRESSLY EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, and further excluding, in each case, Losses against which Sellers would be required to indemnify Purchaser pursuant to Section 14.4 other than Losses associated with claims for indemnity by Seller for the Assumed Obligations in subparts (c), (d) and (e) of Section 14.2.

14.4 Sellers’ Indemnification. Provided that the Closing occurs, Sellers shall, severally but not jointly and severally, release, defend, indemnify and hold harmless Purchaser, its partners, and their respective officers, directors, employees, agents, representatives, members, shareholders, affiliates and subsidiaries (collectively, the “Purchaser Indemnitees”) from and against any and all claims arising out of, or relating to, (a) the Retained Obligations, but only as to matters for which Purchaser has provided Sellers a specific written claim on or before the end of the period of time for which each obligation or liability is retained by Sellers, (b) such Seller’s breach of any of its covenants or agreements contained in Article 9, or (c) the breach of any representation or warranty made by such Seller in Article 7, REGARDLESS OF WHETHER CAUSED OR CONTRIBUTED TO BY THE, JOINT, COMPARATIVE OR CONCURRENT NEGLIGENCE OR STRICT LIABILITY OF ANY OF THE PURCHASER INDEMNITEES, BUT EXPRESSLY EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

14.5 Limitation for Sellers’ Indemnification.

(a) Notwithstanding anything to the contrary contained herein, Sellers’ indemnification obligation under Section 14.4 shall only apply if (a) Purchaser has provided Sellers with written notice claiming indemnification (i) with respect to Retained Obligations, on or before the date on which the applicable Retained Obligation expires pursuant to Section 14.1, and (ii) with respect to breaches of representations, warranties, covenants or agreements, on or before the date on which the applicable representation, warranty, covenant or agreement expires pursuant to Section 15.3.

(b) Purchaser shall bear sole responsibility for the aggregate costs associated with all claims made under Section 14.4 up to a deductible percentage of one percent (1%) of the Purchase Price. It is the intent that the Sellers only be obligated to the extent of the excess of the claims made under Section 14.4 above the deductible percentage of one percent (1%). Notwithstanding the foregoing, claims made by Purchaser in connection with Excluded Assets, with respect to the Retained Obligations in Section 14.1(a)(ii), (v), or with respect to breaches by Sellers of their representations, warranties, covenants and agreements in Section 5.5(e), 7.1, 7.2, 7.3, 7.4, 7.5, 7.7, 7.8, 7.20, 7.21, Article 9 and the special warranty of title in the Conveyance, shall not be subject to the deductible provided in this Section 14.5. The aggregate liability of Sellers pursuant to this Article 14 shall be limited to an amount equal to twelve and one-half percent (12.5%) of the unadjusted Purchase Price. Notwithstanding anything to the contrary in this Agreement, any representation, warranty, covenant or agreement that is qualified by materiality or material adverse effect shall be deemed not to be so qualified for purposes of indemnification pursuant to this Section 14.4. The Parties shall treat, for tax purposes, any amounts paid pursuant to this Article 14 as an adjustment to the Purchase Price.

14.6 Notices and Defense of Indemnified Matters. Each Party shall promptly notify the other Party of any matter of which it becomes aware and for which it is entitled to indemnification from the other Party under this Agreement (“Indemnity Claims”); provided, however, that failure of a Party to so notify any other Party shall not relieve the indemnifying Party of its obligations, except to the extent that such failure results in insufficient time being available to permit the indemnifying Party to effectively defend against any third Person claim. The indemnifying Party shall be obligated to defend, at the indemnifying Party’s sole expense, any litigation or other administrative or adversarial proceeding against the indemnified Party relating to any matter for which the indemnifying Party 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 indemnifying Party in the defense of any such matter at its own expense.

ARTICLE 15

LIMITATIONS ON REPRESENTATIONS AND WARRANTIES

15.1 Disclaimers of Representations and Warranties. The express representations and warranties of Sellers contained in this Agreement are exclusive and are in lieu of all other representations and warranties, express, implied or statutory. EXCEPT FOR THE EXPRESS REPRESENTATIONS OF SELLERS IN THIS AGREEMENT (AND EXCEPT FOR THE SPECIAL WARRANTY OF TITLE TO BE CONTAINED IN THE CONVEYANCE), THE PURCHASER ACKNOWLEDGES THAT SELLERS, AND SELLERS’ REPRESENTATIVES HAVE NOT MADE, AND SELLERS HEREBY EXPRESSLY DISCLAIM AND NEGATE, AND THE PURCHASER HEREBY EXPRESSLY WAIVES, ANY REPRESENTATION OR WARRANTY, EXPRESS, IMPLIED, AT COMMON LAW, BY STATUTE OR OTHERWISE RELATING TO (a) TITLE TO THE ASSETS, (b) PRODUCTION RATES, RECOMPLETION OPPORTUNITIES, DECLINE RATES, OR THE QUALITY, QUANTITY OR VOLUME OF THE RESERVES OF HYDROCARBONS, IF ANY, ATTRIBUTABLE TO THE ASSETS, (c) THE ACCURACY, COMPLETENESS OR MATERIALITY OF ANY INFORMATION, DATA OR OTHER MATERIALS (WRITTEN OR ORAL) NOW, HERETOFORE OR HEREAFTER FURNISHED TO THE QR PARTIES BY OR ON BEHALF OF ANY SELLER,

AND (d) THE ENVIRONMENTAL CONDITION OF THE ASSETS. EXCEPT FOR THE EXPRESS REPRESENTATIONS OF SELLERS IN THIS AGREEMENT, SELLERS EXPRESSLY DISCLAIM AND NEGATE, AND THE QR PARTIES HEREBY WAIVE, AS TO PERSONAL PROPERTY, EQUIPMENT, INVENTORY, MACHINERY AND FIXTURES CONSTITUTING A PART OF THE ASSETS (i) ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, (ii) ANY IMPLIED OR EXPRESS WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, (iii) ANY IMPLIED OR EXPRESS WARRANTY OF CONFORMITY TO MODELS OR SAMPLES OF MATERIALS, (iv) ANY RIGHTS OF PURCHASERS UNDER APPROPRIATE STATUTES TO CLAIM DIMINUTION OF CONSIDERATION OR RETURN OF THE PURCHASE PRICE, (v) ANY IMPLIED OR EXPRESS WARRANTY OF FREEDOM FROM DEFECTS, WHETHER KNOWN OR UNKNOWN, (vi) ANY AND ALL IMPLIED WARRANTIES EXISTING UNDER APPLICABLE LAW, AND (vii) ANY IMPLIED OR EXPRESS WARRANTY REGARDING ENVIRONMENTAL LAWS, THE RELEASE OF MATERIALS INTO THE ENVIRONMENT, OR PROTECTION OF THE ENVIRONMENT OR HEALTH, IT BEING THE EXPRESS INTENTION OF PURCHASER AND SELLERS THAT THE PERSONAL PROPERTY, EQUIPMENT, INVENTORY, MACHINERY AND FIXTURES INCLUDED IN THE ASSETS SHALL BE CONVEYED TO PURCHASER, AND PURCHASER SHALL ACCEPT SAME, AS IS, WHERE IS, WITH ALL FAULTS AND IN THEIR PRESENT CONDITION AND STATE OF REPAIR, AND PURCHASER REPRESENTS TO SELLERS THAT PURCHASER WILL MAKE OR CAUSE TO BE MADE SUCH INSPECTIONS WITH RESPECT TO SUCH PERSONAL PROPERTY, EQUIPMENT, INVENTORY, MACHINERY AND FIXTURES AS PURCHASER DEEMS APPROPRIATE. SELLERS AND THE QR PARTIES AGREE THAT, TO THE EXTENT REQUIRED BY APPLICABLE LAW TO BE EFFECTIVE, THE DISCLAIMERS OF CERTAIN WARRANTIES CONTAINED IN THIS SECTION ARE “CONSPICUOUS” DISCLAIMERS FOR THE PURPOSES OF ANY APPLICABLE LAW, RULE OR ORDER.

15.2 Independent Investigation. Purchaser represents and acknowledges that it is knowledgeable of the oil and gas business and of the usual and customary practices of producers such as Sellers and that it has had (or will have prior to the Closing) access to the Assets, the officers and employees of Sellers, and the books, records and files of Sellers relating to the Assets, and in making the decision to enter into this Agreement and consummate the transactions contemplated hereby, Purchaser has relied solely on the basis of its own independent due diligence investigation of the Assets and upon the representations and warranties made in Article 7, and not on any other representations or warranties of Sellers or any other person or entity.

15.3 Survival. Purchaser’s liability for the representations, warranties, covenants and obligations of Purchaser under this Agreement shall indefinitely survive the Closing. Sellers’ liability for the representations, warranties, covenants and obligations of Sellers under Sections 7.1, 7.2, 7.3, 7.4, 7.5, 7.7, 7.8, 7.20, 7.21 and Article 9 shall survive the Closing indefinitely. Sellers’ liability for the representation and warranty in Section 7.22 shall survive the Closing for the applicable statute of limitations period. The remainder of the representations and warranties of Sellers in Article 7 shall survive Closing for a period of twelve (12) months from the Closing, after which Sellers shall have no liability or obligation in relation thereto except as to matters for which Purchaser has provided Sellers a specific written claim on or

before such termination date; provided, however, notwithstanding anything to the contrary contained herein, the obligation of Sellers with respect to the Excluded Assets shall indefinitely survive the Closing. The remainder of this Agreement shall survive the Closing indefinitely, except as specifically provided herein.

ARTICLE 16
