(c) Notwithstanding anything herein to the contrary, Buyer shall not acquire any right or interest in any properties of Seller other than the Assets or in any proceeds of production produced and sold from the Assets prior to the Effective Time or in any payments due Seller for production from the Assets prior to the Effective Time.

2.3. Adjustments to Base Purchase Price.

(a) To determine the Purchase Price (as herein defined), the Base Purchase Price shall be increased by the following amounts:

(ii) the aggregate amount of any and all operating costs paid by Seller that relate to the Assets for periods from and after the Effective Time (excluding amounts for which the Base Purchase Price is increased pursuant to Section 2.3(a)(i) above), including, but not limited to, lease operating expenses, transportation and marketing expenses, lease payments, severance and production Taxes and producing overhead rates;

(iii) the aggregate amount of any and all capital expenditures actually made by Seller or on Seller’s behalf in accordance with the terms of this Agreement and that relate to the Assets for periods from and after the Effective Time; and

5.6. Environmental Matter Notification.

(a) Until the Closing, Seller shall give prompt notice to Buyer of the occurrence or non-occurrence of any event or condition which came into Seller’s Knowledge and occurred after the date of this Agreement, and which would lead to a reasonable belief that such occurrence or non-occurrence of the event or condition may give rise to an Environmental Liability relating to the Assets, and the remediation (including the cost of any investigations or responses, and fines imposed by any Governmental Authority) of which could reasonably be expected to require the expenditure of more than $50,000.00. Prompt notice shall be made within two (2) business days of Seller’s Knowledge arising as to such event or condition, with such notice being delivered in a form to be received by Buyer within the two (2) day period, followed by additional notification (as necessary) to comply with the notice provisions of this Agreement.

(b) In the event that notice of such matter is provided by Seller (“Seller’s Environmental Notice”), or in the event that Buyer’s additional environmental inspection (“Buyer’s Environmental Inspection”) of the Assets performed after the date of this Agreement (but prior to Closing) identifies an event or condition giving rise to an Environmental Liability the remediation (including any fines imposed by a Governmental Authority) of which could reasonably be expected to require the expenditure of more than $50,000.00, and Buyer is unwilling to accept the Environmental Liability arising from such newly disclosed or identified matter, then Buyer shall provide notice to Seller (“Buyer’s Environmental Notice”) within two (2) business days of identifying or receiving notice of such Environmental Liability (but in all events prior to Closing), of the existence of such Environmental Liability and its unwillingness to accept such condition. If the matter is a result of Buyer’s additional environmental review of the Assets between the date of this Agreement and Closing, said notification by Buyer shall include reasonable detail by the environmental engineering firm used to perform such review to describe the Environmental Liability, and to reasonably support that such Environmental

Liability was not in existence and had not occurred as of the date the Buyer performed its environmental diligence prior to Closing.

(c) If the parties do not reach mutual agreement prior to Closing as to a Purchase Price adjustment for said Environmental Liability, then at Buyer’s election, Buyer may elect for Seller to, and Seller shall thereupon have the option to take all reasonable actions to attempt to, remediate such Environmental Liability to Buyer’s reasonable satisfaction, or to a condition sufficient to receive a No Further Action letter from the applicable Governmental Authority (if a Governmental Authority has required the remediation). If Seller (i) elects not to remediate such environmental condition or cannot complete all remediation activities prior to the Closing or (ii) the Purchase Price adjustment for an Environmental Liability exceeds the Allocated Value for the affected Well, the Allocated Value attributable to the affected Well(s) will be deducted from the Base Purchase Price, and such Well(s) and associated Leasehold will not be conveyed to Buyer at Closing. Seller shall have a period of 90 days after Closing to complete the required level of remediation and upon such remediation there will be a second Closing (to be held 5 days after the parties agree that all remediation obligations above are met) at which Buyer will pay Seller the applicable Purchase Price for the remediated Assets and Seller will assign all such Assets to Buyer using the form of Assignment attached to the Agreement. Any Assets for which the remediation is not completed within said 90 day period shall be considered an Excluded Asset. Seller or Buyer at its option may terminate this Agreement on or before Closing if the remediation activities or the Allocated Value attributable to the affected Assets identified in Buyer’s Environmental Inspection exceeds 20% of the Base Purchase Price. Notwithstanding any of the foregoing, Seller is not required to remediate any identified condition.

ARTICLE VII
ADDITIONAL COVENANTS

7.1. Tax Matters.

(a) Seller shall be responsible, and agrees to hold harmless and indemnify the Buyer Indemnified Parties, for all oil and gas production, severance, ad valorem and other similar Taxes with respect to the Assets for periods (or any portion thereof) or production prior to the Effective Time, in each case to the extent not taken into account under Section 2.3(b). Buyer shall be responsible, and agrees to hold harmless and indemnify the Seller Indemnified Parties, for all oil and gas production, severance, ad valorem and other similar Taxes with respect to the Assets for periods (or any portion thereof) or production after the Effective Time, in each case to the extent not taken into account under Section 2.3(a) but including the items described in Section 2.3(b).

(b) Buyer shall be liable for and shall indemnify Seller for, any sales and use Taxes, conveyance, transfer and recording fees and real estate transfer stamps or Taxes that may be imposed on any transfer of the Assets pursuant to this Agreement. If required by applicable law, Seller shall, in accordance with applicable law, calculate and remit to the applicable Governmental Authority any sales or similar Taxes that are required to be paid as a result of the transfer of the Assets to Buyer and Buyer shall promptly reimburse Seller therefor. If Seller receives notice that any sales and/or use Taxes are due, Seller shall promptly forward such notice to Buyer for handling.

(c) The parties agree to cooperate with each other as reasonably required after the Closing Date in connection with audits and other proceedings with respect to any Taxes relating to the Assets.

(d) Notwithstanding any other provision of this Agreement, the covenants and obligations set forth in this Section 7.1 shall survive until, and any claim for indemnification with respect thereto must be made prior to, the expiration of the applicable statute of limitations with respect to the underlying Tax claim (including any valid extensions).

(e) Notwithstanding anything contained in this Agreement, each party will be solely responsible for its own income and franchise Taxes arising out of or attributable to the Assets and the transactions contemplated by this Agreement.

(f) Seller reserves the right, at or prior to Closing, to assign its rights under this Agreement, solely with respect to all or a portion of the Purchase Price, and/or that portion of the Assets associated therewith, to a Qualified Intermediary (as that term is defined in Section 1.1031(k)-1(g)(4) of the Treasury Regulations, referred to herein as the “QI”) to accomplish this transaction, in whole or in part, as a like-kind exchange (“Like-Kind Exchange”) under Section 1031 of the Code. Buyer hereby (i) consents to Seller’s assignment described above, and (ii) if such an assignment is made, provided Buyer received timely notice thereof, Buyer agrees to pay all or a portion of the Purchase Price, when paid, into the qualified trust account as directed in writing by such Seller.

(g) Buyer reserves the right, at or prior to Closing, to assign its rights under this Agreement with respect to all or a portion of the Assets to Buyer’s QI or to Buyer’s Qualified Exchange Accommodation Titleholder (as that term is defined in Revenue Procedure 2000-37) (the “QEAT”) in connection with effecting a Like-Kind Exchange.

(h) Seller and Buyer acknowledge and agree that a whole or partial assignment of this Agreement to a QI or a QEAT shall not release either Seller or Buyer from, or expand, any of their respective liabilities and obligations to each other under this Agreement. The Party not participating in the Like-Kind Exchange shall not be obligated to pay any additional costs or incur any additional obligations in its sale or purchase, as applicable, of the Assets if such costs are the result of the other party’s Like-Kind Exchange, and the party electing to consummate the sale as a Like-Kind Exchange agrees to hold harmless and indemnify the other party from and against all claims, losses and liabilities, if any, resulting from the Like-Kind Exchange.

7.2. Casualty. If any Asset shall be materially damaged or destroyed by fire or other casualty before the Closing, either party may, at its option, and upon written notice prior to Closing to the other party elect to exclude such Asset from this Agreement. In the event that the Asset to be excluded pursuant to this Section 7.2 is the entirety of a Lease, the Base Purchase Price shall be reduced by the Allocated Value of the portion of the Assets to be excluded. In the event that the Asset sought to be excluded is less than the entirety of a Lease, the Base Purchase Price shall be reduced by a mutually agreed upon amount. If neither party elects to delete such Asset from this Agreement as aforesaid, Seller shall pay the deductible due under any insurance policy or policies insuring the same and deliver to Buyer, at the Closing, any net insurance proceeds actually received by it by reason of such casualty, and assign to Buyer all of its right, title and interest in any claim under any applicable insurance policies in respect of such casualty.

7.3. Consents and Preferential Rights.

(a) The Parties acknowledge that certain of the consents and preferential rights set forth on Schedule 3.2 will, if Seller attempts to assign the Property Agreements affected by such consents, impair the effectiveness of the Assignment of the Assets or terminate

the affected Property Agreement by reason of the attempted assignment (such consents and preferential rights being referred to herein as the “Required Consents”). Seller shall continue to be obligated to use its commercially reasonable efforts to procure all Required Consents set forth on Schedule 3.2 for a period of time ending 90 days following Closing (the “Consent Period”).

(b) If any Required Consent has not been obtained by Seller at or prior to the Closing, Seller will so notify Buyer and the Assets affected by such Required Consents will not be assigned to Buyer at Closing, and the Base Purchase Price will be reduced by an amount equal to the Allocated Value attributable to the affected Asset(s), or interest therein, affected by such outstanding Required Consent in accordance with the provisions of Section 2.6, subject to the further provisions of Section 7.3(c) below.

(c) If any Required Consent not obtained by Closing is not obtained prior to the end of the Consent Period, the affected Asset, or interest therein, will not be assigned to Buyer and neither Seller nor Buyer will have any further obligation under this Agreement with respect to said Asset or interest therein except for Seller’s obligations as to Retained Liabilities; provided, however, that Buyer and Seller may mutually agree to sell and purchase any such excluded Asset or interest therein affected by a Required Consent obtained following the end of the Consent Period. If a Required Consent is obtained during the Consent Period, Buyer will pay Seller the Allocated Value of the applicable Assets as part of the Final Settlement Statement process and Seller will assign the applicable portion of the Assets to Buyer no later than the Final Settlement Date.

7.4. Other Party’s Funds. After the Closing, to the extent either Seller or Buyer receives any funds to which the other party is entitled by reason of its accrual before, or after, as applicable, the Effective Time, and the settlement of such funds is not otherwise provided for in this Agreement (as an adjustment on the Preliminary Settlement Statement, for example), the party receiving the funds shall promptly deliver such funds to the appropriate party. If either Seller or Buyer pays any cost or expense that is properly borne by the other party pursuant to this Agreement, and the payment is not otherwise adjusted pursuant to the Preliminary Settlement Statement or the Final Settlement Statement, the party responsible for such cost or expense shall reimburse, within 10 days of the date it receives notice of such payment, the party who made the payment.

7.5. Amounts Held in Suspense. From and after Closing, Buyer shall maintain a segregated bank account with an initial balance equivalent to the amounts held in suspense as shown in Section 3.4(d) at a bank of Buyer’s selection. Copies of monthly bank account statements on such account shall be delivered to Seller and Seller shall have access to information concerning such account at any time. The funds in such account may be deployed only to make payments of amounts held in suspense to the parties entitled to payment of such amounts or to make escheat payments to the State of Texas or the State of Louisiana as may be required by applicable law. In connection with the preparation of the Final Settlement Statement described in Section 2.6, Seller shall make a good faith estimate of an allocation of the funds remaining after such escheat payments, with amounts (a) not subject to escheat and not subject to viable claims which could be asserted by parties other than Seller, and (b) relating to periods prior to the Effective Date being disbursed to Seller (and Seller shall indemnify and hold Buyer

harmless from any and all third party claims asserted against such amounts released to Seller). Any dispute concerning the disposition of such funds as between Seller and Buyer shall be resolved pursuant to the arbitration procedures set forth in Section 8 of Exhibit A hereto.

To the extent that interest accruing on the suspended amounts prior to the Effective Date is required to be paid in connection with a payment of such funds, Seller shall indemnify Buyer for any required payment of interest accruing prior to the Effective Date, but Buyer shall otherwise indemnify and hold harmless Seller from and against all claims asserted against the amounts held in suspense, to the extent the amounts shown on Schedule 4(d) and all interest accrued thereon from and after the Effective Date.

ARTICLE VIII
SURVIVAL; INDEMNIFICATION

8.1. Limitation on and Survival of Representations and Warranties.

(a) Buyer and Seller acknowledge and agree that no representations or warranties have been made by Buyer or Seller in connection with the transactions contemplated by this Agreement, except for those representations and warranties made in Article III and Article IV hereof.

(b) Subject to Exhibit A and Section 9, all representations and warranties of Seller contained in this Agreement, or in any agreements or instruments executed in connection herewith or delivered pursuant hereto, shall otherwise survive the Closing for a period of twelve months; provided however, that the representations and warranties contained in Section 3.1, 3.2(a)(i), 3.6, and 4.1 shall survive the Closing in each case, until the expiration of the applicable statute of limitations period (the “Corporate and Tax Provisions”). All representations and warranties shall only be effective with respect to any breach or claim when notice of such breach or claim shall have been given in writing to the party in breach or against whom indemnification is sought within such period. Any claim for indemnification for which notice has been given within the prescribed period may be prosecuted to conclusion notwithstanding the subsequent expiration of such period. No party to this Agreement shall be entitled to pursue any remedy for the breach of any representation or warranty to the extent such party was given formal notice of such breach prior to the Closing Date and such party proceeds with the Closing.

8.2. Indemnification by Seller.

(a) Subject to the limitations set forth in Sections 7.1, 8.1 and 8.4, Seller hereby agrees to indemnify and hold Buyer and its employees, officers, directors and affiliates (each a “Buyer Indemnified Party”) harmless from and against any and all claims, demands, suits, proceedings, judgments, losses, liabilities, damages, costs and expenses (including, but not limited to, reasonable attorneys’ fees) (collectively, “Losses”) imposed upon or incurred by any Buyer Indemnified Party as a result of or in connection with any of the following:

(i) Subject to the limitations set forth in Sections 8.1 and 8.4, the breach of a representation or warranty made by Seller in this Agreement or in any agreement or instrument executed in connection herewith or pursuant hereto; or

(ii) the breach of, or default in the performance of, any covenant, agreement or obligation to be performed by Seller, in whatever capacity, pursuant to this Agreement or any agreement or instrument executed in connection herewith or pursuant hereto; and

(iii) the Retained Liabilities.

(b) Within thirty (30) days after receipt by a Buyer Indemnified Party of notice of an Action or other event giving rise to a claim by Buyer (a “Buyer Claim”) with respect to which a Buyer Indemnified Party may be entitled to indemnification under this Section 8.2, the party receiving such notice shall notify (the “Buyer Claim Notice”) Seller in writing of the commencement of such Action or the assertion of such Buyer Claim; provided, however, that failure to give such notice shall not affect the right to indemnification hereunder except to the extent of actual prejudice to Seller. Seller shall have the option, and shall notify the Buyer Indemnified Party in writing within 10 Business Days after the date of the Buyer Claim Notice of their election, either: (A) to participate (at the expense of Seller) in the defense of such Action or Buyer Claim (in which case the defense of such Action or Buyer Claim shall be controlled by the Buyer Indemnified Party) or (B) to take charge of and control the defense of such Action or Buyer Claim (at the expense of Seller). If Seller elects to control the defense, it will not compromise or settle the Action or Buyer Claim if (X) the amount to be paid in settlement exceeds the Maximum Indemnity Amount or (Y) the settlement does not include a provision releasing the Buyer Indemnified Party from all liabilities with respect thereto. If Seller fails to notify the Buyer Indemnified Party of their election within the applicable response period, then Seller shall be deemed to have elected not to control the defense of such Action or Buyer Claim. If Seller elects to control the defense of any Action or Buyer Claim, the Buyer Indemnified Party shall have the right to employ separate counsel and participate in the defense of such Action or Buyer Claim, but the fees and expenses of such counsel shall be at the expense of the Buyer Indemnified Party unless: (1) the named parties in such Action or Buyer Claim (including any impleaded parties) include both the Buyer Indemnified Party and the Seller and the Buyer Indemnified Party shall have been advised by such counsel that there may be one or more legal defenses available to it that are different from or additional to those available to the Seller, or (2) the Buyer Indemnified Party has reasonably determined that Losses that may be incurred may exceed either individually, or when aggregated with other Buyer Claims, the Maximum Indemnity Amount (in which case, Seller shall not have the right to control the defense of such Action or Buyer Claim on behalf of the Buyer Indemnified Party, it being understood, however, that Seller shall not, in connection with such Action or Buyer Claim, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) and that all such fees and expenses shall be reimbursed as they are incurred).

(c) If Seller does not control the defense of any Action or Buyer Claim, then the Buyer Indemnified Party may settle such Action or Buyer Claim with the prior written consent of Seller (not to be unreasonably withheld).

8.3. Indemnification by Buyer.

(a) Subject to the limitations set forth in Sections 8.1 and 8.4, Buyer hereby agrees to indemnify and hold Seller and its employees, officers, managers, members, and affiliates (each a “Seller Indemnified Party”) harmless from and against any and all Losses imposed upon or incurred by any Seller Indemnified Party (any of such Losses by Seller, a “Seller Claim”) as a result of or in connection with any of the following:

(i) any breach of a representation or warranty made by Buyer in this Agreement or in any agreement or instrument executed in connection herewith or pursuant hereto;

(ii) the breach of or default in the performance by Buyer of any covenant, agreement or obligation to be performed by Buyer pursuant to this Agreement or any agreement or instrument executed in connection herewith or pursuant hereto; or

(iii) the Assumed Liabilities.

(b) Within 30 days after receipt by a Seller Indemnified Party of notice of the commencement of an Action or other event giving rise to a Seller Claim with respect to which a Seller Indemnified Party may be entitled to indemnification, the party receiving such notice shall notify (the “Seller Claim Notice”) Buyer in writing of the commencement of such Action or the assertion of such Seller Claim; provided, however, that failure to give such notice shall not affect the right to indemnification hereunder except to the extent of actual prejudice to Buyer. Buyer shall have the option, and shall notify each indemnified party in writing within 10 Business Days after the date of the Seller Claim of its election, either: (A) to participate (at its own expense) in the defense of the Action or Seller Claim (in which case the defense of such Action or Seller Claim shall be controlled by the Seller Indemnified Party) or (B) to take charge of and control defense of such Action or Seller Claim (at its own expense). If Buyer fails to notify the Seller Indemnified Party of its election within the applicable response period, then Buyer shall be deemed to have elected not to control the defense of such Action or Seller Claim. If Buyer elects to control the defense of any Action or Seller Claim, each Seller Indemnified Party shall have the right to employ separate counsel and participate in the defense of any such Action or Seller Claim, but the fees and expenses of such counsel shall be at the expense of the Seller Indemnified Party unless: (1) the named parties in such Action or Seller Claim (including any impleaded parties) include both the Seller Indemnified Party and Buyer and the Seller Indemnified Party shall have been advised by such counsel that there may be one or more legal defenses available to it that are different from or additional to those available to Buyer, or (2) Seller has reasonably determined that Losses that may be incurred may exceed either individually, or when aggregated with other Seller Claims, the Maximum Indemnity Amount (in which case, Buyer shall not have the right to assume the defense of such Action or Seller Claim on behalf of the Seller Indemnified Party, it being understood, however, that Buyer shall not, in connection with such Action or Seller Claim be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) and that such fees and expenses shall be reimbursed as they are incurred).

(c) If Buyer does not control the defense of any Action or Seller Claim, then the Seller Indemnified Party or parties may settle such Action or Seller Claim with the prior written consent of Buyer (not to be unreasonably withheld).

8.4. Limitation of Liability.

(a) Notwithstanding the foregoing, (i) Seller shall not be obligated to indemnify the Buyer Indemnified Parties, and Buyer shall not be obligated to indemnify the Seller Indemnified Parties, unless and until the amount of all Losses incurred by Buyer, or by Seller, as the case may be, exceeds 1% of the Purchase Price in the aggregate, in which event the party seeking indemnity may recover all Losses incurred from the first dollar, and (ii) Seller’s maximum liability for Losses under Section 8.2 and Buyer’s maximum liability for Losses under Section 8.3 shall be, in each case, 50% of the Purchase Price (the “Maximum Indemnity Amount”).

(b) Title Defects are not subject to the limitations set forth in this Section 8.4, but only to the separate limitations applicable to such defects as set forth in Exhibit A.

8.5. Exclusive Remedy. Except as provided in Section 8.6, after the Closing, the Buyer’s sole and exclusive recourse against Seller for any Loss or claim of Losses arising out of or relating to this Agreement shall be expressly limited to the provisions of this Article VIII.

8.6. Title Defects. Buyer’s sole and exclusive remedy with respect to Title Defects or Losses arising thereunder, shall be as provided in the Title Defect Mechanism

8.7. Environmental Liabilities. Except as expressly stated herein, Buyer is not relying upon any representation or warranty of Seller as to the environmental condition of the Assets.

8.8. Disclaimer of Other Warranties.

(a) The express representations and warranties of the parties contained in this Agreement are exclusive and are in lieu of all other representations and warranties, express, implied, or statutory. EXCEPT AS OTHERWISE PROVIDED HEREIN, SELLER HAS NOT MADE, AND SELLER HEREBY EXPRESSLY DISCLAIMS AND NEGATES, AND BUYER HEREBY EXPRESSLY WAIVES, ANY REPRESENTATION OR WARRANTY, EXPRESS, IMPLIED, AT COMMON LAW, BY STATUTE OR OTHERWISE RELATING TO (A) PRODUCTION RATES, RECOMPLETION OPPORTUNITIES, DECLINE RATES, GAS BALANCING INFORMATION OR THE QUALITY, QUANTITY, OR VOLUME OF THE RESERVES OF HYDROCARBONS, IF ANY, ATTRIBUTABLE TO THE ASSETS, (B) THE ACCURACY, COMPLETENESS OR MATERIALITY OF ANY INFORMATION, DATA OR OTHER MATERIALS (WRITTEN OR ORAL) NOW, HERETOFORE OR HEREAFTER FURNISHED TO BUYER BY OR ON BEHALF OF SELLER, (C) THE ENVIRONMENTAL CONDITION OF THE PROPERTIES, (D) ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, (E) ANY IMPLIED OR EXPRESS WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, (F) ANY IMPLIED OR EXPRESS WARRANTY OF CONFORMITY TO MODELS OR SAMPLES OF MATERIALS, (G) ANY RIGHTS OF

PURCHASERS UNDER APPROPRIATE STATUTES TO CLAIM DIMINUTION OF CONSIDERATION, (H) ANY AND ALL IMPLIED WARRANTIES EXISTING UNDER APPLICABLE LAW, (I) THE TITLE TO ANY OF THE ASSETS, (J) THE CONDITION OF THE ASSETS, IT BEING DISTINCTLY UNDERSTOOD THAT THE ASSETS ARE BEING SOLD “AS IS,” “WHERE IS,” AND “WITH ALL FAULTS AS TO ALL MATTERS”; IT BEING THE EXPRESS INTENTION OF BOTH BUYER AND SELLER THAT SUBJECT TO AND WITHOUT LIMITING SELLER’S EXPRESS REPRESENTATION AND WARRANTIES CONTAINED HEREIN, THE PERSONAL PROPERTY, EQUIPMENT AND FIXTURES INCLUDED WITHIN THE PROPERTIES ARE TO BE CONVEYED TO BUYER IN THEIR PRESENT CONDITION AND STATE OF REPAIR, AND THAT BUYER HAS MADE OR CAUSED TO BE MADE SUCH INSPECTIONS AS BUYER DEEMS APPROPRIATE. SELLER AND BUYER 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.

(b) Buyer is aware that the Properties have been used for exploration, development, production, handling, transporting and/or processing of oil and gas and that there may be petroleum, produced water, wastes, or other materials located on or under the Properties or associated with the premises. Some equipment and sites included in the Properties may contain asbestos, hazardous substances, or naturally occurring radioactive material (“NORM”). NORM may affix or attach itself to the inside of ▇▇▇▇▇, materials, and equipment as scale, or in other forms; the ▇▇▇▇▇, materials, and equipment located on the Properties or included in the Properties may contain NORM and other materials or hazardous substances; and NORM-containing material and other materials or Hazardous Substances may have been buried, come in contact with the soil or water, or otherwise been disposed of on the Properties. Special procedures may be required for the remediation, removal, transportation, or disposal of materials, asbestos, hazardous substances, and NORM from the Properties.

EXHIBIT A

PROCEDURE FOR CLAIMING TITLE DEFECTS AND
ADJUSTING THE BASE PURCHASE PRICE

1. Title Procedure. From the date this Agreement is executed until 3:00 pm Central Standard Time on the date that is 5 Business Days prior to the Closing Date (the “Title Examination Period”), Buyer may make written claims in accordance with this Exhibit A with respect to any Title Defect claimed by Buyer.

2. Notice of Asserted Title Defects. From time to time prior to the expiration of the Title Examination Period, as soon as reasonably practicable following Buyer’s identification of Title Defects with respect to the Leases and/or the ▇▇▇▇▇, Buyer will furnish to Seller written notices specifying in detail each matter which, in Buyer’s opinion, constitutes a Title Defect to a Lease or Well and which Buyer wishes to assert as a Title Defect, together with the dollar amount allocated to each such asserted Title Defect (“Title Defect Amount”) as estimated by Buyer (each such notice being called a “Title Defect Notice”). The Title Defect Notice shall include all documents in support of Buyer’s assertion of a Title Defect.

3. Cure of Title Defects.

	(a)		If Seller elects to cure a Title Defect set forth in a Title Defect Notice, then Seller may attempt to cure such Title Defect during the Cure Period. As used in this Agreement, “Cure Period” means that period of time from 5:00 p.m. on the date Seller receives the Title Defect Notice, until 5:00 p.m. on the date that is 90 days after the Closing Date. On or before expiration of the Cure Period, Seller may give Buyer written evidence of any curative actions which in Seller’s determination cure or reduce the Title Defect Amount of any Title Defect asserted by Buyer, including an explanation in reasonable detail of any claimed reduction in the Title Defect Amount.

	(b)		Leases affected by Title Defects, if the Title Defects have been cured to Buyer’s reasonable satisfaction, will be referred to as “Cured Leases.”

4. Notice in Response to Buyer’s Notice. No later than the day that is 5 Business Days prior to Closing, Seller shall give written notice to Buyer as to each asserted Title Defect (“Response Notice”), stating:

	(a)		that it admits the existence of the Title Defect and accepts Buyer’s estimate of the Title Defect Amount, in which event, the Title Defect Amount will be deducted from the Base Purchase Price in accordance with Section 2.3(b) of the Agreement;

	(b)		that it disputes the existence of the Title Defect or disagrees with the Title Defect Amount estimated by Buyer for such Title Defect, in which event, in Seller’s sole discretion, the Seller may exclude the affected Asset

Exhibit A — Title Defect Mechanism - Page 1

thereby reducing the Base Purchase Price in accordance with Section 2.3 (provided that Buyer may waive the assertion of such Title Defect within seven (7) days after Seller makes such election, in which event such Asset shall not be excluded,) (b) or the Seller may elect to have the Title Defect Amount deducted from the Base Purchase Price in accordance with Section 2.3(b) of the Agreement, and the Title Defect or dispute as to Title Defect Amount handled in accordance with the procedures established in this Title Defect Mechanism and the portion of the Assets affected by the asserted Title Defect will not be conveyed to Buyer at Closing, provided that if such asserted Title Defect is later determined to be cured or to not have been a Title Defect or upon such time as the Title Defect Amount is finally determined to be less than the asserted Title Defect Amount by Buyer, then Buyer will pay for the portion of the Assets affected by such asserted or cured Title Defect (reduced by any finally determined Title Defect Amount) and Seller will assign all such Assets to Buyer at the second Closing contemplated in (c)(ii)(1) below; provided, further, however that any portions of the Assets affected by Title Defects, which Title Defects have not been cured by Seller as of the end of the Cure Period, will be treated for all purposes as if they were Excluded Assets; or

(c)

that it admits the existence of the Title Defect and Buyer’s estimate of the Title Defect Amount, but intends to cure the asserted Title Defect, in which event Buyer’s asserted Title Defect Value will be included in the Base Purchase Price, and:

	(i)		the portion of the Assets affected by the Title Defect will not be conveyed to Buyer at Closing;

	(ii)		Seller will have until the end of the Cure Period to attempt to cure, to Buyer’s reasonable satisfaction;

	(1)		there will be a second Closing, on the Final Settlement Date. At the second Closing, Seller will pay Buyer for all portions of the Assets affected by Title Defects which have not been cured to Buyer’s reasonable satisfaction by Seller during the Cure Period, and Buyer will assign all such Assets to Seller using the form of Assignment attached to the Agreement; and

	(2)		any portions of the Assets affected by Title Defects, which Title Defects have not been cured by Seller as of the end of the Cure Period, will be treated for all purposes as if they were Excluded Assets.

5. Other Matters in Seller’s Response Notice. If Seller disagrees with Buyer’s assertion of the existence of a Title Defect or the Title Defect Amount with respect thereto, Seller’s Response Notice shall also specify in reasonable detail Seller’s grounds for such

Exhibit A — Title Defect Mechanism - Page 2

disagreement, the Title Defect Amount estimated by Seller therefor, or both, as the case may be. If not resolved, either Seller or Buyer may require that any unresolved dispute with respect to the existence of a Title Defect or the Title Defect Amount therefor be submitted to arbitration as provided in Section 8 of this Exhibit A.

6. Release. Buyer shall not make any claims, and hereby fully and finally releases Seller from any liability, obligations or damages with respect to such claims, for Title Defects to the extent Buyer does not properly provide a Title Defect Notice for any such Title Defect prior to the end of the Title Examination Period.

7. Method of Determining Title Defect Amounts. Without limiting Seller’s right to dispute the existence of a Title Defect, Title Defect Amounts for each asserted Title Defect shall be determined as follows:

	(a)		If the Title Defect results from a Lien or similar encumbrance, other than a Permitted Encumbrance, the Title Defect Amount will be the amount of money required to remove the Lien or similar encumbrance.

	(b)		If the Title Defect relates to failure of title to the entirety of a Lease, the Title Defect Amount shall be the Allocated Value for that Lease and Seller shall have the Cure Period to cure such Title Defect. If the Title Defect is not cured to Buyer’s reasonable satisfaction during the Cure Period, Buyer shall have the right but not the obligation to have such Lease placed on Schedule 1.29 as an Excluded Asset.

	(c)		If the Title Defect would result in Seller’s Net Revenue Interest in a Well on a Lease being less than the interest shown for the relevant Lease or Well on Schedule 3.3(b) and Seller’s Working Interest in such well or Lease would not be proportionately reduced, the Title Defect Amount will be an amount equal to the product of the Allocated Value for the relevant Lease or Well, multiplied by the percentage reduction in such Net Revenue Interest as a result of such Title Defect.

	(d)		If the Title Defect results from any matter not described in paragraphs (a), (b) or (c) above, then the Title Defect Amount shall be a portion of the Allocated Value for that Lease, said portion to be equal to the difference between the value of Seller’s title to such Lease without such Title Defect and with such Title Defect (assuming the value without such Title Defect to be the Allocated Value specified for such Lease) and Buyer and the Seller agree to negotiate in good faith to determine such Title Defect Amount.

	(e)		If a Title Defect is not currently effective or does not affect Seller’s title to a Lease throughout the entire useful life of such Lease, such fact shall be taken into account in determining the Title Defect Amount.

Exhibit A — Title Defect Mechanism - Page 3

(f)

If any Title Defect is reasonably susceptible of being cured at a cost less than the Title Defect Amount determined in subsections (a) through (e), the Title Defect Amount shall be the reasonable cost and expense of curing such Title Defect.

8. Arbitration.

	(a)		If Buyer or Seller elects to submit any dispute to arbitration as specifically provided in this Exhibit A, then such party shall notify the other party in writing. Within 15 days, Seller and Buyer agree to jointly select an arbitrator. The arbitrator shall be an experienced oil and gas attorney, familiar by training and experience with U.S. oil and gas legal and business matters including titles and oil and gas transactions. This person shall be the sole arbitrator (the “Arbitrator”) to hear and decide all existing disputes regarding asserted Title Defects and Title Defect Amounts. The Arbitrator chosen shall be impartial and independent of the parties. If Seller and Buyer are unable to agree on the Arbitrator within the fifteen-day period, upon request by either party, the Referral Firm shall promptly select an Arbitrator with the qualifications set forth in this paragraph.

	(b)		Any arbitration hearing, if one is desired by the Arbitrator, shall be held in Houston, Texas, or such other location acceptable to both parties and the Arbitrator. The Arbitrator may elect to conduct the proceeding by written submissions from the Seller and Buyer with exhibits, including interrogatories, supplemented with appearances by Buyer and Seller as the Arbitrator may desire. The arbitration proceeding, subject only to the terms hereof, shall be conducted informally and expeditiously and in such a manner as to result in a good faith resolution as soon as reasonably possible under the circumstances. The decision of the Arbitrator with respect to such remaining disputed matters shall be reduced to writing and binding on the parties. Judgment upon the award(s) rendered by the Arbitrator may be entered and execution had in any court of competent jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement. Seller and Buyer, respectively, shall bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the Arbitrator shall be borne one-half by Seller and one-half by Buyer.

	(c)		The arbitration shall commence as soon as possible after the Arbitrator is selected in accordance with the provisions of this Exhibit A. In fulfilling his or her duties with respect to determining the amount of a Title Defect Amount, the Arbitrator may consider such matters as, in the opinion of the Arbitrator, are necessary or helpful to make a proper valuation; however, the Arbitrator shall be bound by those factors set forth in Section 8 of this Exhibit A. Furthermore, the Arbitrator may consult with and engage disinterested third parties to advise the Arbitrator including, without

Exhibit A — Title Defect Mechanism - Page 4

limitation, geologists, geophysicists, petroleum engineers, title and oil and gas lawyers, accountants and consultants, and the fees and expenses of such third parties shall be considered to be charges and expenses of the Arbitrator. The sole remedy in any arbitration award shall be resolution of alleged Title Defects and Title Defect Amounts which shall then be applied as provided in this Exhibit A and the Arbitrator shall not award any other remedy, including, without limitation, equitable relief, actual damages, consequential, exemplary or punitive damages, attorneys’ fees or interest reflecting the time value of money.

	(d)		Any replacement Arbitrator, should one become necessary, shall be selected in accordance with the procedure provided above for the initial selection of an Arbitrator.

	(e)		As to any determination of amounts owing under the terms of this Exhibit A, no lawsuit based on such claimed amounts owing shall be instituted by either Buyer or Seller, other than to compel arbitration proceedings or enforce the award of the Arbitrator.

	(f)		All privileges under state and federal law, including attorney-client and work-product privileges, shall be preserved and protected to the same extent that such privileges would be protected in a federal or state court proceeding applying state or federal law, as the case may be.

9. Title Defect Remedies. Seller’s sole responsibility and Buyer’s sole and exclusive remedy for the reduction in value of Seller’s title to a Lease or Well resulting from the existence of a Title Defect shall be as provided in this Exhibit A and Seller shall not be liable for any Losses in respect of Title Defects and Title Defect Amounts, except to the extent provided under this Exhibit A.

10. Limitations of Title Defect Amount. Notwithstanding the foregoing, there shall be no adjustment to the Base Purchase Price in accordance with this Exhibit A unless and until the Title Defect Amounts exceed $500,000 in the aggregate, in which event the Base Purchase Price shall be adjusted for all Title Defect Amounts from the first dollar.

11. Capitalized Terms. Capitalized terms used herein, if not defined herein, will have the meaning given to such term in the Agreement.

FORM OF FIRPTA AFFIDAVIT

CERTIFICATE OF NON-FOREIGN STATUS

Section 1445 of the Internal Revenue Code provides that a transferee of a U.S. real property interest must withhold tax if the transferor is a foreign person. For U.S. tax purposes (including Section 1445), the owner of a disregarded entity (which has legal title to a U.S. real property interest under local law) will be the transferor of the property, rather than the disregarded entity. To inform the transferee that withholding of tax is not required upon the disposition of a U.S. real property interest by ▇▇▇▇▇▇▇▇ Petroleum Company, L.L.C. (“Seller”), the undersigned hereby certifies under penalties of perjury the following on behalf of Seller:

	1.		Seller is not a foreign corporation, foreign partnership, foreign trust, or foreign estate (as those terms are defined in the Internal Revenue Code and Income Tax Regulations) nor a nonresident alien for U.S. income tax purposes;

	2.		Seller is not a disregarded entity as defined in Treasury Regulation Section 1.1445-2(b)(2)(iii);

	3.		Seller’s U.S. employer identification number is _____________; and

	4.		Seller’s office address is ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇, ▇▇▇▇▇.

Seller understands that this certification may be disclosed to the Internal Revenue Service by transferee and that any false statement contained herein could be punished by fine, imprisonment, or both.

Under penalties of perjury I declare that I have examined this certification and to the best of my knowledge and belief it is true, correct and complete, and I further declare that I have authority to sign this document on behalf of Seller.

obligations of the Parties which by their nature would survive the termination of this Agreement (including the Parties’ respective obligations under Sections 4, 5, and 16), shall survive the termination of this Agreement indefinitely.

3. Cooperation.

(a) From and after the Effective Date, each Party covenants and agrees to conduct its operations on the Leases as a prudent operator with due regard for the other Party’s rights and interests to facilitate the development of the Leases, including due regard for the other Party’s Equipment.

(b) Buyer shall have the exclusive right to drill, operate, produce, and sell Hydrocarbons from ▇▇▇▇▇ completed within the Shallow Rights under the Leases, and Seller shall have the exclusive right to drill ▇▇▇▇▇ completed within the Deep Rights through the Shallow Rights, and to drill, complete, operate, produce, and sell Hydrocarbons from ▇▇▇▇▇ completed within the Deep Rights under the Leases.

(c) Each Party shall notify the other prior to commencing operations on any Lease, providing reasonable detail with respect to the planned operations. Further, the Parties agree to maintain a regular sharing of information and correspondence between each other concerning their respective operations on the Leases.

(d) Buyer covenants that none of its operations in the Shallow Rights shall unreasonably interfere with Seller’s present and future rights to obtain permits prior to drilling or to drill, operate, complete, and produce Hydrocarbons from the Deep Rights. Seller covenants that none of its operations in the Deep Rights shall unreasonably interfere with Buyer’s present and future rights to obtain permits prior to drilling or to drill, operate, complete, and produce Hydrocarbons from the Shallow Rights.

(e) In connection with their respective operations, each Party further covenants not to unreasonably interfere with the surface operations of the other Party, including the laying of pipelines. Each Party agrees to use commercially reasonable efforts to accommodate requests by the other Party regarding rights and agreed terms to share use, access, and/or ownership of any and all Surface Rights. Except as otherwise provided in this Agreement (including Section 5), however, neither Party shall have the right to use any Equipment of the other Party in connection with its operations, without such Party’s prior written consent (which consent may be granted or denied at the sole discretion of such Party).

(f) Unless required by the terms of the Leases or by Legal Requirement, neither Party shall, without at least thirty (30) days prior written notice to and subsequent consent from the other Party, undertake to (i) dispose of, encumber, surrender, release, relinquish, or otherwise adversely affect any of the rights or interests of the other Party in, on, or under the Leases, (ii) waive, compromise, or settle any material right or claim with respect to any of the other Party’s rights or interests in the Leases, (iii) pool, unitize, or otherwise modify or terminate any of the other Party’s interests in the Leases, or (iv)

take any other action reasonably expected to be materially adverse or detrimental to the other Party’s rights and interests in the Leases, including such other Party’s Equipment.

(g) Upon reasonable notice, the Parties shall furnish, or cause to be furnished to each other, access, during normal business hours, to such information relating to the Leases as is available and is reasonably necessary for financial reporting and accounting matters, the preparation and filing of any tax returns, reports, forms, or the defense of any tax claim or assessment and any other contractual or property management obligations.

4. Joint Use Of Roads. Subject to the terms of existing agreements, each Party shall have the right to reasonable joint use of any access roads constructed by the other Party for use in its operations on the Leases. Each Party shall cooperate with the other Party to maintain the roads in generally as good condition as existed prior to such joint use. Each Party shall commence repairs of any damages it causes to such roads within thirty (30) days after causing such damage, and complete such repairs with commercially reasonable diligence.

5. Plugging and Abandonment of ▇▇▇▇▇.

(a) Buyer shall not at any time abandon, relinquish, surrender, or otherwise permit to expire its leasehold interest in any Lease, or plug and abandon the last producing well or ▇▇▇▇▇ capable of production from the Shallow Rights on the applicable Lease acreage, without first giving Seller written notice of such desire and intention at least sixty (60) days before said leasehold interest is to be abandoned, relinquished, surrendered, or otherwise permitted to expire, or the last producing well or ▇▇▇▇▇ capable of producing from the Shallow Rights on the applicable Lease is to be plugged and abandoned. Seller shall have thirty (30) days after receipt of such notice within which to notify Buyer whether Seller elects to take over the leasehold interest of Buyer in the applicable Lease. If Seller elects to take over the leasehold interest of Buyer in any Lease, Buyer shall promptly assign to Seller such leasehold interest, using the form of assignment in Exhibit B-1 for a Texas Lease or Exhibit B-2 for a Louisiana Lease.

(b) With respect to any of Buyer’s ▇▇▇▇▇ that are not the last well producing or capable of producing from the Shallow Rights on a Lease, if Buyer determines to permanently plug and abandon such well, Buyer shall give written notice to Seller sixty (60) days in advance, and Seller shall have thirty (30) days after receipt of such notice within which to notify Buyer whether Seller elects to take over the leasehold interest of Buyer in the applicable Lease, insofar and only insofar as it covers the wellbore for such well. Failure by Seller to respond within such time period shall constitute an election by Seller not to take over such leasehold interest. If Seller elects to take over the leasehold interest of Buyer in any Lease, Buyer shall promptly assign to Seller such leasehold interest, together with all of Buyer’s interest in said well and associated equipment, and the right to use the wellbore to rework or complete and produce from any zone or formation, using the form of assignment in Exhibit B-1 for a Texas Lease or Exhibit B-2 for a Louisiana Lease.

(c) If Seller elects not to take over any such well, Buyer shall, in compliance with all relevant law and lease obligations, properly plug and abandon any and all ▇▇▇▇▇ which Seller does not elect to take over, and shall, within a reasonable time thereafter, remove all leasehold material and debris placed on the leased premises by Buyer and restore the applicable surface of the leased premises, all at Buyer’s sole risk and expense.

6. Schedule 6 Leases: Leases Being Maintained as to the Deep Rights by Production from the Shallow Rights.

(a) Buyer shall permit Seller to have reasonable access, at Seller’s sole risk and cost, to the ▇▇▇▇▇ being operated by Buyer on the Schedule 6 Leases.

7. Schedule 7 Leases: Leases Being Maintained as to the Deep Rights by Payment of Delay Rentals or Shut-in Royalty from ▇▇▇▇▇ Drilled in the Shallow Rights.

(a) Buyer shall give Seller notice, no less than forty-five (45) days before any delay rental or shut-in royalty payment is due under a Schedule 7 Lease, if Buyer does not intend to pay such delay rental or shut-in royalty.

(b) Seller may proceed to make any such delay rental or shut-in royalty payment which Buyer does not intend to pay, whereupon Buyer shall assign to Seller all rights in the Leases or portions thereof which would not be maintained in the absence of such payment, without recourse or warranty.

(c) Seller shall notify Buyer if it commences operations on the Deep Rights in any Schedule 7 Lease, at which time Buyer’s obligations under this Section shall be suspended. If such operations do not result in commercial production sufficient to maintain the Deep Rights in such Schedule 7 Lease, or if commercial production is obtained but thereafter ceases, Seller shall notify Buyer of such event, whereupon Buyer’s obligations under this Section shall resume.

8. Schedule 8 Leases: Primary Term Leases Having No Production or Operations, No Remaining Delay Rentals, and No Shut-in ▇▇▇▇▇ Drilled.

(a) If neither Party has commenced operations on a Schedule 8 Lease by the date which is six (6) months before the expiration of its primary term, each Party, upon request of the other Party, agrees to meet in person or by phone to attempt to reach a mutual decision whether to commence operations in the Shallow Rights or Deep Rights under such Lease, attempt to renew or extend such Lease (subject to Section 10 below), or allow the Lease to expire. There shall be no obligation on either Party to commence operations on a Schedule 8 Lease in the absence of a mutual agreement.

9. Schedule 9 Leases: Leases with Current Operations on or Production from the Deep Rights.

(a) Seller shall not at any time abandon, relinquish, surrender, or otherwise permit to expire its leasehold interest in any Schedule 9 Lease or plug and abandon the last producing well or ▇▇▇▇▇ capable of production from the Deep Rights on the applicable lease acreage, without first giving Buyer written notice of such desire and intention at least sixty (60) days before said leasehold interest is to be abandoned, relinquished, surrendered, or otherwise permitted to expire, or the last producing well or ▇▇▇▇▇ capable of producing from the Deep Rights on the applicable lease is to be plugged and abandoned. Buyer shall have thirty (30) days after receipt of such notice within which to notify Seller whether Buyer elects to take over the leasehold interest of Seller in the applicable lease. If Buyer elects to take over the leasehold interest of Seller any Schedule 9 Lease, Buyer shall promptly assign to Seller such leasehold interest, using the form of Assignment in Exhibit B-1 for a Texas lease or Exhibit B-2 for a Louisiana lease.

(b) With respect to any of Seller’s ▇▇▇▇▇ that are not the last well producing or capable of producing from the Deep Rights on a Schedule 9 Lease, if Seller determines to permanently plug and abandon such well, Seller shall give written notice to Buyer sixty (60) days in advance, and Buyer shall have thirty (30) days after receipt of such notice within which to notify Seller whether Buyer elects to take over the leasehold interest of Seller in the applicable lease, insofar and only insofar as it covers the wellbore for such well. Failure by Buyer to respond within such time period shall constitute an election by Buyer not to take over such leasehold interest. If Buyer elects to take over the leasehold interest of Seller in any lease, Seller shall promptly assign to Buyer such leasehold interest, together with all of Seller’s interest in said well and associated equipment, and the right to use the wellbore to rework or complete and produce from any zone or formation, using the form of Assignment in Exhibit B-1 for a Texas lease or Exhibit B-2 for a Louisiana lease.

(c) If Buyer elects not to take over any such well, Seller shall, in compliance with all relevant law and lease obligations, properly plug and abandon any and all ▇▇▇▇▇ which Buyer does not elect to take over, and shall, within a reasonable time thereafter, remove all leasehold material and debris placed on the leased premises by Seller and restore the applicable surface of the leased premises, all at Seller’s sole risk and expense.

10. Renewals and Extensions.

(a) If either Party obtains a renewal, replacement by new lease, or other extension of a Lease (collectively, a “Renewal Lease”), it shall promptly notify the other Party in writing of such acquired Renewal Lease. Such notice shall include a copy of the Renewal Lease, plat, and all of the related terms and conditions under which the Renewal Lease was acquired, including any bonus consideration and land costs (collectively, the “Renewal Lease Acquisition Costs”). Buyer or Seller (as applicable) shall have thirty (30) days after receipt of the offer to notify the other Party in writing of its intent to acquire the Shallow Rights or Deep Rights (as applicable) in such Renewal Lease. Failure to respond within such time period shall constitute an election not to acquire the Shallow Rights or Deep Rights (as applicable) in such Renewal Lease.

(b) If the non-acquiring Party elects not to acquire the Shallow Rights or Deep Rights (as applicable) in such Renewal Lease, then such Renewal Lease shall not be subject to this Agreement. In addition, if Buyer elects not to acquire the Shallow Rights in a Renewal Lease acquired by Seller, then Buyer shall promptly reassign to Seller the applicable Lease being extended, renewed, or replaced by such Renewal Lease, using the form of assignment in Exhibit B-1 for a Texas Lease or Exhibit B-2 for a Louisiana Lease, whereupon such Lease shall no longer be subject to this Agreement.

(c) If Seller elects to acquire the Deep Rights in a Renewal Lease acquired by Buyer, Buyer shall execute and deliver an assignment to Seller of the Deep Rights therein, using the form of assignment in Exhibit B-1 for a Texas Renewal Lease or Exhibit B-2 for a Louisiana Renewal Lease, and upon receipt and acceptance of same, Seller shall reimburse Buyer for fifty percent (50%) of Buyer’s Renewal Lease Acquisition Costs for such Renewal Lease. If Buyer elects to acquire the Shallow Rights in a Renewal Lease acquired by Seller, Seller shall execute and deliver an assignment to Buyer of the Shallow Rights therein, using the form of assignment in Exhibit B-1 for a Texas Renewal Lease or Exhibit B-2 for a Louisiana Renewal Lease, and upon receipt and acceptance of same, Buyer shall reimburse Seller for fifty percent (50%) of Seller’s Renewal Lease Acquisition Costs for such Renewal Lease. Thereafter, such Renewal Lease shall be subject to this Agreement.

11. Royalties. Each Party shall be solely responsible for the payment of any and all royalty due on its own production, including shut-in royalties.

12. Notice of Ownership Changes. If either Party receives notice from a third party of any change in ownership of any royalty, delay rental, third party working interest, or other interest in any Lease, it shall promptly provide the other Party with a copy of such notice and any supporting documents included therewith.

13. Top Leases. Top Leases shall be treated as Renewal Leases under Section 10 above.

14. Ad Valorem Taxes. Each Party shall be responsible for ad valorem taxes on its own production from the Leases. If ad valorem taxes are assessed on a Lease or tract basis rather than a well-by-well basis, then the Parties shall agree to a reasonable allocation of such taxes based on their respective sales of Hydrocarbons from the Lease or tract during the relevant tax period.

15. Indemnification. Seller shall defend, indemnify, and hold harmless each Buyer Indemnified Party for, and shall pay to the Buyer Indemnified Party the amount of any Losses incurred by the Buyer Indemnified Party arising from Seller’s operations on the Leases, whether or not based upon strict liability or caused by the sole or concurrent negligence (whether active or passive) of any of Buyer Indemnified Party, or any third party, unless such injury was occasioned solely by the gross negligence or intentional tort of any Buyer

Indemnified Party. Likewise, Buyer shall defend, indemnify, and hold harmless each Seller Indemnified Party for, and shall pay to the Seller Indemnified Party the amount of any Losses incurred by the Seller Indemnified Party arising from Buyer’s operations on the Leases, whether or not based upon strict liability or caused by the sole or concurrent negligence (whether active or passive) of any Seller Indemnified Party, or any third party, unless such injury was occasioned solely by the gross negligence or intentional tort of any Seller Indemnified Party. The Parties agree that the obligations of the indemnifying Party to indemnify the indemnified party shall be without regard to the negligence or strict liability of the indemnified party, whether the negligence or strict liability is active, passive, joint, concurrent, or sole. The foregoing is a specifically bargained for allocation of risk among the Parties, which the Parties agree and acknowledge satisfies the express negligence rule and conspicuousness requirement under Texas law.

16. Disclaimer of Joint Liability. This Agreement shall not create the relationship of a partnership or joint venture between the Parties, and no single act done by either Party pursuant to the provisions hereof shall operate to create such relationship, nor shall the provisions of this Agreement be construed as creating such relationship. The liability of the Parties shall be several and not joint or collective, and each Party shall be responsible only for its own obligations as herein set forth.

17. Governing Law. This Agreement shall be governed by the laws of the State of Texas without regard to conflicts of laws principles.

18. Jurisdiction; Service of Process. Any action or proceeding seeking a temporary or preliminary injunction to enforce any provision of, or based on any right arising out of, this Agreement or the must be brought in the courts of the State of Texas, County of ▇▇▇▇▇▇, or, if it has or can acquire jurisdiction, in the United States District Court for the Southern District of Texas (Houston Division), and each Party consents to the jurisdiction of such courts (and of the appropriate appellate courts) for such limited purpose in any such action or proceeding and waives any objection to venue laid therein for such limited purpose. Process in any action or proceeding referred to in the preceding sentence may be served on either Party anywhere in the world.

19. Notices. All written notices, requests, and other communications under this Agreement shall be provided in accordance with the terms of the PSA.

20. Entire Agreement and Modification. Except for the PSA, this Agreement supersedes all prior agreements between the Parties with respect to its subject matter, and together with the PSA constitutes a complete and exclusive statement of the terms of the agreement between the Parties with respect to its subject matter. This Agreement may not be amended except by a written agreement executed by both Parties. No representation, promise, inducement, or statement of intention with respect to the

subject matter of this Agreement has been made by either Party that is not embodied in this Agreement, and neither Party shall be bound by or liable for any alleged representation, promise, inducement, or statement of intention not so set forth.

21. Assignments, Successors, and No Third-Party Rights. Neither Party may assign any of its rights under this Agreement without the prior written consent of the other Party (which consent may be granted or denied at the sole discretion of the other Party), and in the event of such consent, such assignment nevertheless shall not relieve such Party of any of its obligations under this Agreement without the prior written consent of the other Party. Subject to the preceding sentence, this Agreement shall apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the Parties. Nothing expressed or referred to in this Agreement shall be construed to give any Person other than the parties to this Agreement or any other agreement contemplated herein (and Buyer Indemnified Party and Seller Indemnified Party who are entitled to indemnification under Section 17), any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement. This Agreement, any other agreement contemplated herein, and all provisions and conditions hereof and thereof, are for the sole and exclusive benefit of the parties to this Agreement and such other agreements (and Buyer Indemnified Party and Seller Indemnified Party who are entitled to indemnification under Section 17), and their respective successors and permitted assigns.

22. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree shall remain in full force and effect to the extent not held invalid or unenforceable.

23. Section Headings, Construction. The headings of Sections, Exhibits, and Schedules in this Agreement are provided for convenience only and shall not affect its construction or interpretation. All references to “Section,” “Exhibit,” or “Schedule” refer to the corresponding Section, Exhibit, or Schedule of this Agreement. Unless expressly provided to the contrary, the words “hereunder,” “hereof,’ “herein,” and words of similar import are references to this Agreement as a whole and not any particular Section, Exhibit, Schedule, or other provision of this Agreement. Each definition of a defined term herein shall be equally applicable both to the singular and the plural forms of the term so defined. All words used in this Agreement shall be construed to be of such gender or number, as the circumstances require. Unless otherwise expressly provided, the word “including” does not limit the preceding words or terms. Each Party has had substantial input into the drafting and preparation of this Agreement and has had the opportunity to exercise business discretion in relation to the negotiation of the details of this Agreement. This Agreement is the result of arm’s-length negotiations from equal bargaining positions. This Agreement shall not be construed against either Party, and no consideration shall be given or presumption made on the basis of who drafted this Agreement or any particular provision hereof or who supplied the form of Agreement.

24. Time of Essence. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.
