6.1 Information.

EXCEPT AS OTHERWISE SET FORTH IN THIS AGREEMENT, BUYER REPRESENTS AND WARRANTS THAT ON THE CLOSING, BUYER WILL ACCEPT THE ASSETS AT CLOSING IN THEIR PRESENT CONDITION, “AS IS AND WHERE IS.” BUYER ACKNOWLEDGES AND AGREES THAT, EXCEPT AS OTHERWISE SET FORTH IN THIS AGREEMENT AND IN THE CONVEYANCES, SELLERS HAVE MADE NO REPRESENTATIONS OR WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, WRITTEN OR ORAL, AS TO THE ACCURACY OR COMPLETENESS OF THE BACKGROUND MATERIALS OR ANY OTHER INFORMATION RELATING TO THE ASSETS FURNISHED BY OR ON BEHALF OF SELLERS OR TO BE FURNISHED TO BUYER OR ITS REPRESENTATIVES, INCLUDING WITHOUT LIMITATION ANY INTERNAL APPRAISALS AND/OR INTERPRETIVE DATA OF SELLERS. Buyer acknowledges and affirms that it has relied and will rely solely upon Sellers’ representations, warranties and covenants in this Agreement and on its independent analysis, evaluation and investigation of, and judgment with respect to, the business, economic, legal, tax or other consequences of this transaction, including its own estimate and appraisal of the extent and value of the petroleum, natural gas and other reserves associated with the Assets.

6.2 Knowledge and Experience. Buyer (i) is engaged in the business of exploring for and/or producing oil and gas or other valuable minerals as an ongoing business and (ii) is purchasing the Assets for its own account for investment purposes and

not with the intent to resell the Assets in violation of any federal or state securities laws. Buyer is an experienced and knowledgeable investor in oil and gas properties, has the financial and business expertise to evaluate the merits and risks of the transactions covered by this Agreement and has relied solely on the basis of its own independent investigation of the Assets for all purposes. In acquiring the Assets, Buyer is acting in the conduct of its own business and not under any specific contractual commitment to any third party, or any specific nominee agreement with any third party, to transfer to, or to hold title on behalf of, such third party, with respect to all or any part of the Assets. Buyer acknowledges that it has had the opportunity to seek the advice of persons it deemed appropriate concerning the consequences of the provisions of this Agreement and hereby waives any and all rights to claim that it is an unsophisticated investor in oil and gas properties.

6.3 No Warranty. Buyer acknowledges that, except as otherwise set forth in this Agreement and in the Conveyances, Sellers have not made any representation, covenant or warranty, express or implied, at common law, by statute or otherwise, relating to the condition of the Assets, including, without limitation, any implied or express warranty of merchantability, of fitness for any particular purpose, or of conforming to models or samples of materials as to any personal property, fixtures or structures conveyed pursuant to this Agreement.

Buyer is, and after Closing shall continue to be, qualified to own federal, oil, gas and minerals leases in the MMS Gulf of Mexico Outer Continental Shelf Region, including meeting all bonding or financial instruments requirements of the MMS or other Governmental Authorities.

ARTICLE 7

7. TITLE

7.1 Title Defects. Buyer shall notify Sellers in writing of any Title Defect in the Assets after discovering the Title Defect but in any event on or before five (5) Business Days prior to Closing (the “Due Diligence Period”). For the purpose of this Agreement, a “Title Defect” shall mean a material deficiency which individually per property exceeds Fifty Thousand Dollars ($50,000) in one (or more) of the following respects (other than Permitted Encumbrances):

7.1.1 Adverse Claims. Sellers’ title as to all or part of an Asset is subject to (i) an outstanding mortgage which is not released on or before Closing; (ii) a deed of trust which is not released on or before Closing; (iii) a lien or encumbrance which is not released on or before Closing; or (iv) a pending claim or cause of action in which a competing ownership interest in an Asset is claimed or implied.

7.1.2 Decreased Net Revenue Interest. Sellers own less than the net revenue interest shown on Exhibit “B” for a particular Asset.

7.1.3 Increased Working Interest. Sellers own more than the working interest shown on Exhibit “B” for a particular Asset without a proportionate increase in the corresponding net revenue interest shown on Exhibit “B”.

7.1.4 Reversions. An Asset is subject to reduction by the exercise by a third-party of a reversionary, back-in, or other similar right not reflected on Exhibit “A” or Exhibit “B” or not reflected in any materials received by Buyer prior to the date hereof.

7.2 Additional Interests. During the Due Diligence Period, Buyer shall notify Sellers in writing if Buyer determines that Sellers have a lesser working interest (without a proportionate decrease in the corresponding net revenue interest) or a greater net revenue interest with respect to all or any part of an Asset than that set forth on Exhibit “B”. During the Due Diligence Period, Sellers may notify Buyer in writing of any increase in net revenue interest or decrease in working interest

(without a corresponding decrease in net revenue interest) of an Asset than that set forth on Exhibit “B” (“Additional Interest”).

7.3 Notices. Any Title Defect notice by Buyer pursuant to Section 7.1 or Additional Interest notice by Sellers pursuant to Section 7.2 shall include appropriate documentation to substantiate the applicable position and the estimated value of the Title Defect or Additional Interest. If any such notice is not timely delivered, the claimant shall thereafter have no right to assert such Title Defect or Additional Interest as the basis for an adjustment to the Base Purchase Price; provided, however, that this waiver shall not apply with regard to any matters or claims that Buyer may have the right to assert under the special warranty of title in the Conveyances.

7.4 Adjustments to Base Purchase Price. Upon timely delivery of a notice under Article 7 pursuant to Section 7.1 or 7.2, either by Buyer or by Sellers, Buyer and Sellers shall meet and use their reasonable commercial efforts to agree on the validity of any claims for Title Defects or Additional Interests remaining unresolved as of the Closing and the amount of any Base Purchase Price adjustment using the following criteria:

(a) Liquidated Charges. If the adjustment is based upon a lien, encumbrance, or other charge upon an Asset which is liquidated in amount or which can be estimated with reasonable certainty, then the adjustment shall be the sum necessary to be paid to the obligee to remove the encumbrance from the affected Asset.

(b) Ownership Variance. If the adjustment is based upon Sellers owning a lesser or greater net revenue interest with a corresponding proportionate lesser or greater working interest in a Well than that shown on Exhibit “B”, then the adjustment shall be proportionate to the amount allocated to the affected Well on Exhibit “C”. If the adjustment is based upon a lesser or greater net revenue interest without a corresponding proportionate lesser or greater working interest in a Well than that shown on Exhibit “B”, then the Parties shall use their best efforts to agree upon a mutually acceptable Base Purchase Price adjustment.

(c) Valuation of Title Defects. If the adjustment is for an item other than as set forth in (a) or (b) above, Buyer and Sellers shall endeavor to mutually agree on the amount of the adjustment to the Base Purchase Price. If the parties cannot agree to the existence of a Title Defect or Additional Interests or the applicable adjustment, the matter shall be resolved in accordance with the dispute resolution provisions in Section 20.3. Any such item shall be referred to as an “Open Defect”. Notwithstanding any of the preceding provisions of this Article 7, all adjustments applicable to Title Defects or Additional Interests shall be made prior to Closing which Closing shall be extended until resolution of any disputes relating to the Title Defects or Additional Interests; provided, however, that if

adjustments for alleged Title Defects, Environmental Defects, Casualty Defects and Open Defects do not, in the aggregate, exceed 10% of the Base Purchase Price, then Closing shall occur as to the other Assets that are not subject to the dispute (with the portion of the Assets subject to the dispute being excluded, and the Base Purchase Price reduced for the entire Allocated Values thereof) and Closing shall subsequently occur with respect to the Assets made the subject of the dispute within thirty (30) days following the final resolution of the dispute.

For all Title Defects, subject to the provisions of Section 7.5, Sellers shall elect to either (i) in the case of Title Defects, either: (1) sell to Buyer the entire Asset(s) affected by the Title Defect but reduce the Base Purchase Price by the portion of the Allocated Value set forth on Exhibit “C” attributable to such affected Assets, (2) exclude from this transaction the Assets affected by the Title Defect and reduce the Base Purchase Price for the entire Allocated Value of those Assets so excluded; or (ii) in the case of an Additional Interest, sell to Buyer the entire Assets affected by the Additional Interest at the original Allocated Value set forth on Exhibit “C” attributable to such Interests proportionately increased to reflect such Additional Interest.

7.5 Deductible for Title and Environmental Defects. Notwithstanding the provisions set forth above, a Title Defect or Environmental Defect shall not result in an adjustment to the Base Purchase Price unless the aggregate net value of the sum of (a) all Title Defects with respect to the Assets and (b) all Environmental Defects agreed to by the parties is greater than five percent (5%) of the Base Purchase Price (the “Deductible Amount”). In such event, the Base Purchase Price on the Closing shall be adjusted by the aggregate net value of the sum of (a) all Title Defects and (b) all Environmental Defects which collectively exceed the Deductible Amount.

7.6 Termination. If, because of Title Defects, Environmental Defects and Casualty Defects, in the aggregate, the Base Purchase Price is to be adjusted downward by an amount exceeding ten percent (10%) of the Base Purchase Price, either Party may, upon written notice to the other Party, cancel this Agreement.

ARTICLE 8

8. ENVIRONMENTAL AND ENVIRONMENTAL INDEMNITY

8.1 Acceptance of Environmental Condition. Buyer shall give Sellers notice (an “Environmental Notice”) of any fact or circumstance that indicates a violation of a currently existing Environmental Law associated with an Asset (“Environmental Defect”). For the purpose of this Agreement, an Environmental Defect shall mean a material deficiency which individually per property exceeds Fifty Thousand Dollars ($50,000) and complies with all of the following conditions precedent:

(a) The Environmental Notice must be received by Sellers as soon as reasonably practical after discovery of the Environmental Defect by Buyer, but in any event on or before ten (10) Business Days prior to the Closing Date;

(b) The Environmental Notice must be based on credible and probative evidence substantiated in good faith by Buyer’s environmental experts (which may include internal employees or personnel of Buyer, its affiliates or third parties) that shows it is more likely than not that there exists an Environmental Defect;

(c) The evidence referred to in Section 8.1(b) must be fully described, substantiated in good faith by Buyer’s environmental experts, and in the case of documentary evidence, enclosed.

(d) The Environmental Notice must reasonably describe the remediation and/or restoration required to remedy the Environmental Defect, or the potential damages claimed or likely to be claimed by a third party (the “Cleanup”), each as recommended or estimated in good faith by Buyer’s environmental experts; and

(e) To the extent practicable, the Environmental Notice must state Buyer’s good faith estimate of the amount of potential Loss to be incurred by Buyer as a result of the Environmental Defect. For purposes of this Agreement, the term “Loss” shall include any estimated Cleanup, costs, losses, expenses, liabilities (including civil fines), damages, demands, suits, sanctions, reasonable fees and expenses of attorneys, technical experts and expert witnesses.

If Buyer does not provide Sellers with an Environmental Notice within the period set forth above, then at Closing, Buyer shall be deemed to have accepted such Asset and to have waived Buyer’s right to assert an Environmental Defect with respect to the Assets.

8.2 Remedy for Environmental Defects. If Buyer gives a valid Environmental Notice in accordance with Section 8.1, Sellers may provide for one of the remedies in Section 8.2(a) with respect to the Environmental Defect that is subject to such Environmental Notice, but each such remedy, and the aggregate of all remedies, shall be limited in accordance with Section 7.5.

(a) Remedy. If Buyer delivers a valid Environmental Notice to Sellers, Sellers, at their election, shall have the option of (i) remediating the Environmental Defect and resolving all Losses arising from such Environmental Defect to the reasonable satisfaction of Buyer or the appropriate state and federal agencies having jurisdiction, (ii) contesting the existence of an Environmental Defect or Buyer’s estimate of the amount of all Losses associated with the Environmental Defect pursuant to Section 8.2(c), (iii) paying Buyer’s good faith estimate of the amount of

all Losses associated with the Environmental Defect in the form of a reduction to the Purchase Price (an “Environmental Adjustment”), or (iv) excluding the Asset pursuant to Section 8.2(b).

(b) Exclusion of Affected Asset. At Sellers’ option, an exclusion adjustment may be made in an amount equal to the Allocated Value of the Asset which is the subject of a valid Environmental Notice. In such event Sellers shall retain the Asset and the Base Purchase Price shall be reduced by the Allocated Value of such Asset.

(c) Contested Environmental Defects. If Sellers contest the existence of any Environmental Defect or Buyer’s estimate of the Loss associated with such Environmental Defect, Sellers shall notify Buyer within five (5) Business Days after Sellers’ receipt of the Environmental Notice. The notice shall state the basis for Sellers’ contest of the Environmental Defect or the estimate of the Cleanup cost. Within two (2) Business Days after Buyer’s receipt of the notice, representatives of Sellers and Buyer, knowledgeable in environmental matters, shall meet in person or otherwise, and, prior to Closing, either (i) agree to reject the Environmental Defect, in which case Buyer shall waive the Environmental Defect, or (ii) agree on the validity of the Environmental Defect and the estimated Loss, in which case Sellers shall have the options described in Section 8.2(a) (except the right to contest) and Section 8.2(b) (Exclusion of Affected Asset). If Sellers and Buyer cannot agree on either option (i) or (ii) in the preceding sentence, the Environmental Defect or the estimated Loss subject to the Environmental Notice shall be resolved in accordance with the dispute resolution provisions set forth in Section 20.3. Notwithstanding any of the preceding provisions of this Section 8.2(c), all Environmental Adjustments shall be made prior to Closing, which Closing shall be extended until resolution of any disputes relating to the Environmental Defects; provided, however, that if adjustments for alleged Title Defects, Environmental Defects, Casualty Defects and Open Defects do not, in the aggregate, exceed 10% of the Base Purchase Price, then Closing shall occur as to the other Assets that are not subject to the dispute (with the portion of the Assets subject to the dispute being excluded, and the Base Purchase Price reduced for the entire Allocated Values thereof) and Closing shall subsequently occur with respect to the Assets made the subject of the dispute within thirty (30) days following the final resolution of the dispute unless Seller elects exclusion of the Affected Assets. IT IS SPECIFICALLY UNDERSTOOD AND AGREED THAT ONCE AN ENVIRONMENTAL DEFECT HAS BEEN REMEDIATED AND ALL LOSSES RELATED TO SUCH ENVIRONMENTAL DEFECT HAVE BEEN RESOLVED, BUYER SHALL ASSUME ANY AND ALL FUTURE ENVIRONMENTAL OBLIGATIONS ASSOCIATED WITH SUCH PROPERTY.

(d) Implementing Cleanup. If Sellers elect to Cleanup an Environmental Defect pursuant to Section 8.2(a), Sellers shall select the means and methods of effecting the Cleanup in accordance with applicable Environmental Law, applicable industry standards, and any applicable agreement, provided, however, that Sellers shall not be required to plug and abandon any currently unplugged xxxxx if the cost thereof would be customary and normal site remediation costs assumed by Buyer in the transfer of the Assets hereunder, including without limitation, plugging and abandonment of Xxxxx. Sellers’ responsibility for remediation under this Section 8.2 shall be limited to a standard appropriate for the use of an Asset for oil and gas activities and in accordance with all applicable laws.

8.3 Acceptance of Environmental Condition. SUBJECT TO THE OTHER TERMS AND PROVISIONS SET FORTH IN THIS AGREEMENT, UPON CLOSING, BUYER AGREES TO ACCEPT THE ENVIRONMENTAL CONDITION OF THE ASSETS, INCLUDING, BUT NOT LIMITED TO, COSTS TO CLEAN UP OR REMEDIATE; AND SUBJECT TO THE OTHER TERMS AND PROVISIONS SET FORTH IN THIS AGREEMENT, BUYER HEREBY AGREES TO RELEASE SELLERS FROM ANY AND ALL LIABILITY AND RESPONSIBILITY THEREFORE AND AGREES TO INDEMNIFY, DEFEND, AND HOLD SELLERS HARMLESS FROM ANY AND ALL CLAIMS, CAUSES OF ACTION, FINES, EXPENSES, COSTS, LOSSES, AND LIABILITIES WHATSOEVER (INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEYS’ FEES AND COSTS) IN CONNECTION WITH THE ENVIRONMENTAL CONDITION OR BUYER’S FAILURE TO PROPERLY REMEDIATE THE CONDITION. BUYER ACKNOWLEDGES AND AFFIRMS THAT THE ASSETS HAVE BEEN UTILIZED FOR THE PURPOSE OF EXPLORATION, PRODUCTION AND DEVELOPMENT OF OIL AND GAS, AND EXCEPT AS OTHERWISE SET FORTH IN THIS AGREEMENT, AT CLOSING, THE ASSETS WILL BE ACQUIRED IN THEIR “AS IS, WHERE IS” ENVIRONMENTAL CONDITION. BUYER HAS CONDUCTED AN INDEPENDENT INVESTIGATION OF THE PHYSICAL AND ENVIRONMENTAL CONDITION OF THE ASSETS, TO THE EXTENT BUYER DEEMS NECESSARY OR APPROPRIATE.

8.4 NORM. Buyer acknowledges that the Assets have been used for exploration, development and production of oil, gas and water and that there may be petroleum, produced water, wastes or other materials located on, under or associated with the Interests. Equipment and sites included in the Assets may contain 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 or included in the Assets may contain NORM and other wastes or hazardous substances/materials; and NORM containing material and other wastes or hazardous substances/materials may have been buried, come in contact with the soil or otherwise been disposed of on or around the Assets. Special procedures may be required for the remediation, removal, transportation or disposal of

wastes, asbestos, hazardous substances/materials, including hydrogen sulfide gas and NORM from the Assets. From and after the Closing, Buyer shall assume responsibility for the control, storage, handling, transporting and disposing of or discharge all materials, substances and wastes from the Assets (including produced water, hydrogen sulfide gas, drilling fluids, NORM and other wastes), whether present before or after the Effective Time, in a safe and prudent manner and in accordance with all applicable Environmental Laws (as defined below).

8.5 Environmental Indemnities. EXCEPT AS OTHERWISE SET FORTH IN THIS AGREEMENT OR IN THE CONVEYANCES, THIS SALE IS MADE ON AN “AS IS, WHERE IS” BASIS AND BUYER RELEASES SELLERS FROM ANY LIABILITY WITH RESPECT TO THE ENVIRONMENTAL CONDITION OF THE ASSETS, WHETHER OR NOT CAUSED BY OR ATTRIBUTABLE TO SELLERS’ NEGLIGENCE. FROM AND AFTER CLOSING, SUBJECT TO THE OTHER TERMS AND PROVISIONS SET FORTH IN THIS AGREEMENT, BUYER SHALL BE LIABLE TO SELLERS FOR AND SHALL, IN ADDITION, INDEMNIFY, DEFEND, RELEASE AND HOLD SELLERS HARMLESS FROM AND AGAINST ANY AND ALL CLAIMS, IN FAVOR OF ANY THIRD PARTY OR ENTITY FOR INJURY, ILLNESS OR DEATH OF ANY PERSON(S) OR FOR DAMAGE, LOSS, POLLUTION OR CONTAMINATION OF ANY REAL OR PERSONAL PROPERTY, GROUNDWATER OR THE ENVIRONMENT ATTRIBUTABLE TO THE ENVIRONMENTAL CONDITION OF THE ASSETS, INCLUDING, WITHOUT LIMITATION, CLAIMS ARISING UNDER ENVIRONMENTAL LAWS OR, FOR ANY OTHER CLAIMS ARISING DIRECTLY OR INDIRECTLY FROM, OR INCIDENT TO, THE USE, OCCUPATION, OWNERSHIP, OPERATION, CONDITION (WHETHER LATENT OR PATENT), MAINTENANCE OR ABANDONMENT OF ANY OF THE ASSETS AND WHETHER ARISING FROM OR CONTRIBUTED TO BY THE ACTIVE, PASSIVE, JOINT, SOLE OR CONCURRENT NEGLIGENCE, OR STRICT LIABILITY OF SELLERS, OR SELLERS’ CONTRACTORS OR SUBCONTRACTORS OR THE OFFICERS, DIRECTORS, AGENTS OR EMPLOYEES OF SELLERS’ CONTRACTORS OR SUBCONTRACTORS, INCLUDING ANY STRICT LIABILITY UNDER ENVIRONMENTAL LAWS, REGARDLESS OF WHETHER ANY SUCH CLAIMS RESULT FROM ANY CONDITIONS, EVENTS, ACTIONS OR INACTIONS ARISING, OCCURRING OR ACCRUING PRIOR TO, ON OR AFTER THE EFFECTIVE TIME. Buyer and Sellers shall treat all information regarding any environmental conditions as confidential and shall not make any contact with any Governmental Authority or third party regarding same without written consent from the other Party unless so required by applicable law.

ARTICLE 9

9. THIRD-PARTY PREFERENTIAL RIGHTS TO PURCHASE AND CONSENTS

9.1 Third Party Notices. Sellers will request, from the appropriate parties (and in accordance with the documents creating such rights and/or requirements), any consent or approval of any third party, person or Governmental Authority (“Consents”) and shall send out notices for all options, rights of first refusal, or similar preferential purchase rights burdening any of the Assets (each a “Preferential Purchase Right”) applicable to the Assets, in compliance with the terms of all Contracts providing for such Preferential Purchase Rights. Sellers shall promptly give notices to third parties holding either (i) any Consent rights, or (ii) Preferential Purchase Rights. Sellers shall use all commercially reasonable efforts, but without obligation to incur any unreasonable cost or expense, to obtain waivers of, or to comply with, any such Preferential Purchase Right prior to Closing. If prior to Closing, the Preferential Purchase Right with respect to an Asset has not been exercised or waived and the time for exercising such Preferential Purchase Right has not expired, the Closing Date with respect to such Asset will be extended to on or before five (5) business days after the date upon which the time to exercise such Preferential Purchase Right has expired without first being exercised. In such event, the Base Purchase Price shall be adjusted in connection with the Closing on the remaining Assets by the dollar amount allocated to the affected Asset as set forth on Exhibit “C”.

9.2 Third-Party Exercise. If a third-party exercises a Preferential Purchase Right of the Assets, the affected Asset shall be removed from this Agreement and the Base Purchase Price shall be adjusted by the dollar amount allocated to the affected Asset as set forth on Exhibit “C”.

11. POST-CLOSING OBLIGATIONS

Sellers and Buyer agree to the following post-Closing obligations:

11.1 Recordation and Filing of Documents. After the Closing, Buyer shall file or record the Conveyances in the appropriate county and governmental records. Buyer shall provide a copy of same, including recording date, to Sellers, all at the sole cost of Buyer.

11.2 Records. Within ten (10) Business Days after the Closing, Sellers will furnish Buyer the Records. All costs associated with delivering or copying the Records shall be borne solely by Buyer. Insofar as Sellers reasonably believe the Records may be needed or useful in connection with federal, state or local regulatory or tax matters or resolution of disputes, litigation, or contract compliance issues, Buyer (for a period of seven (7) years after the Closing) shall further make available to Sellers or their affiliates (at the location of such Records in Buyer’s organization) access to the Records during normal business hours, upon not less than two (2) Business Days prior written request by Sellers, and Sellers shall have the right to copy at its own expense and retain such copies of the Records as Sellers, in good faith, believe may be useful or needed in connection with the above-described matters. If, however, Buyer elects to destroy any of the Records prior to the expiration of the seven (7) year period, Buyer shall give to Sellers written notice of such intent at least thirty (30) days prior to such destruction, and Sellers shall have the option, at their expense, of having such Records delivered to it.

11.3 Final Settlement Statement. Sellers shall issue a final settlement statement covering all adjustments, without duplication, to the Base Purchase Price that were not included in the Closing Settlement Statement (the “Final Settlement Statement”) within one hundred twenty (120) days after Closing. Buyer shall respond with objections and proposed corrections within thirty (30) days of the issuance of the Final Settlement Statement. If Buyer does not respond with objections and the support therefore to the Final Settlement Statement in writing within thirty (30) days of the issuance of the Final Settlement Statement, said Statement shall be deemed approved by Buyer. In the event that Buyer does respond and objects within this time period, the Parties shall meet within fifteen (15) days following receipt of Buyer’s objections and attempt to resolve the disputed items. If the Parties are unable to resolve the disputed items by the end of such fifteen-day period, the dispute shall be resolved in accordance with the dispute resolution provisions set forth in Section 20.3. After approval by both Parties (or after final resolution of the same under Section 20.3), the net adjustment due pursuant to the Final Settlement Statement for the Assets conveyed will be summarized and a net check or invoice will be sent to the Buyer or Sellers, as the case may be. Buyer or Sellers, as the case may be, agrees to promptly pay such invoice within ten (10) days after receipt by Buyer.

11.4 Suspense Accounts. As set forth and itemized on Schedule 11.4 attached hereto, Sellers currently maintains suspense accounts pertaining to oil and gas heretofore produced comprising monies payable to royalty owners, mineral owners and other persons with an interest in production that Sellers have been unable to pay (the “Suspense Accounts”). A downward adjustment to the Base Purchase Price will be made at Closing to reflect the Suspense Accounts as of the Closing Date. The Suspense Accounts will be further adjusted, if necessary, in the Final Settlement Statement. Subject to the other provisions hereof, Buyer shall assume full and complete responsibility and liability for proper payment of the funds comprising the Suspense Accounts as set forth on the “Final Suspense Account Statement,” which shall be provided by Sellers to Buyer with the Final Settlement Statement required in Section 11.3, (including any liability under any unclaimed property law or escheat statute). Buyer agrees to indemnify, defend and hold Sellers, their parent, subsidiary and affiliated entities, together with their respective officers, directors, employees, agents and their respective successors and assigns, harmless from and against any and all liabilities, claims, demands, penalties and expenses (including reasonable attorneys’ fees) arising out of or pertaining to the proper payment and administration of the Suspense Accounts in accordance with the Final Suspense Account Statement, limited, however to the total dollar amount of the Suspense Accounts. In connection with the final settlement regarding the Final Suspense Account Statement, within one hundred twenty (120) days after Closing, Sellers shall (a) supplement and update Schedule 11.4 and provide the same to Buyer in connection therewith, and (b) provide to Buyer a listing showing all proceeds from production attributable to the Assets that are held in suspense which are owing to third-party owners of royalty, overriding royalty, working interest or other interests in respect of production of Hydrocarbons attributable to the Assets, and Sellers shall deliver to Buyer, to the extent available, in electronic

format, the owner’s name, owner number, social security or other tax identification number, the reason for the suspense and the amount suspended funds payable for each entry; provided, however, that notwithstanding anything stated herein to the contrary, until the first anniversary of the Closing Date, Sellers shall retain all responsibility and liability for (i) statutory penalties and interest, if any, attributable to the suspended funds accruing prior to the Effective Time, and (ii) penalties and interest, if any, attributable to the suspended funds accruing prior to the Effective Time, payable to any State under existing escheat or unclaimed property statutes.

11.5 Bonds, Letters of Credit and Guaranty. Buyer acknowledges that none of the bonds, letters of credit and guaranties, if any, posted by Sellers or its affiliates with Governmental Authorities or third parties and relating to the Assets are transferable to Buyer. Except to the extent that Buyer will, as of Closing, be covered by the bonds of the operators of the applicable Assets, then on or before the Closing Date, Buyer shall obtain, or cause to be obtained in the name of Buyer, replacements for such bonds, letters of credit and guaranties, to the extent such replacements are necessary to permit the cancellation as of Closing of the bonds, letters of credit and guaranties posted by Sellers and/or their affiliate.

12. TAXES

12.1 Property Taxes. All ad valorem taxes, real property taxes, and similar obligations (“Real Property Taxes”) applicable to the Assets with respect to the tax period in which the Effective Time occurs (the “Current Tax Period”) shall be apportioned between Sellers and Buyer as of the Effective Time based on the immediately preceding tax period’s assessment, regardless of the taxing agency’s basis for calculating such assessment, unless the Current Tax Period’s assessment is known, in which case that assessment shall be used for apportionment. Sellers will reimburse Buyer for Sellers’ portion of the Current Tax Period at Closing or in connection with any post-closing settlement provided for herein. Buyer shall pay, and defend and hold Sellers harmless, with respect to payment of all Real

Property Taxes on the Assets for the Current Tax Period and thereafter, regardless of the taxing agency’s basis for calculating such taxes, together with any interest or penalties assessed thereon. If Sellers pay the Real Property Taxes assessed for the Current Tax Period, Buyer agrees to reimburse Sellers for Buyer’s portion of said taxes at Closing or in connection with any post-closing settlement provided for herein.

12.2 Production Taxes. All taxes (other than Real Property, income, franchise, or similar taxes) imposed on or with respect to the production of oil, natural gas, or other hydrocarbons or minerals, or the receipt of proceeds therefrom (including, but not limited to, severance, production and excise taxes) shall be apportioned between the parties based upon the respective shares of production taken by the parties. Payment or withholding of all such taxes that have accrued prior to the Effective Time and filing of all statements, returns and documents pertinent thereto shall be the responsibility of Sellers. Payment or withholding of all such taxes that have accrued from and after the Effective Time and the filing of all statements, returns and documents incident thereto shall be the responsibility of Buyer. In the event any such taxes attributable to the Assets and to periods on or after the Effective Time become due and payable prior to Closing, Sellers shall timely pay and satisfy the same, and appropriate adjustments therefor shall be made to the Base Purchase Price under Section 3.3 above.

12.3 Other Taxes. As may be required by relevant taxing agencies, Sellers shall collect and Buyer shall pay at Closing all applicable state and local sales tax, use tax, gross receipts tax, business license tax, and other taxes attributable to the consummation of the transactions under this Agreement except taxes imposed by reason of income to (or capital of) Sellers. The tax collected shall be based upon the Allocated Values as provided in Section 3.4 and shall be added to the Base Purchase Price at Closing. Any state or local tax specified above, inclusive of any penalty and interest, assessed at a future date against Sellers with respect to the transaction covered herein shall be paid by Buyer or, if paid by Sellers, Buyer shall promptly reimburse Sellers therefor. Any documentary stamp tax which may be due shall be paid by Buyer.

ARTICLE 13

13. OWNERSHIP OF ASSETS

13.1 Distribution of Production. All oil in storage above the pipeline connection or gas beyond the meters at the Effective Time shall be credited to Sellers, less applicable royalties and severance taxes. For Seller-operated Assets, Sellers have gauged the oil in storage and read all gas meter charts as of the Effective Time. For Seller non-operated Assets, the quantity of such oil in storage or gas beyond the meters shall be determined on the same basis as that used for Seller-operated Assets based on operator reports or applicable state regulatory agency production reports or records. As part of the Closing Settlement Statement, the price for such oil in storage shall be at the price that Sellers have contracted to sell the oil on the

Effective Time. If there is no such price, the price shall be the average of the two highest prices that are posted at the Effective Time (plus any premium) by other purchasing companies, as determined by Sellers in the field or locality where the Interests are located for oil of like grade and gravity. Title to the oil in storage for both Seller-operated and Seller non-operated Assets shall pass to Buyer as of the Effective Time, and an upward adjustment shall be made to the Base Purchase Price due at Closing, less applicable royalties and severance taxes.

13.2 Proration of Income and Expenses. Except as otherwise provided in this Agreement, all proceeds (including proceeds held in suspense or escrow), receipts, credits, and income attributable to the Assets for all periods of time prior to the Effective Time shall belong to Sellers, and all proceeds, receipts, credits, and income attributable to the Assets for all periods of time from and after the Effective Time shall belong to Buyer. Except as otherwise provided in this Agreement, all costs, expenses, disbursements, and obligations attributable to the Assets for periods of time prior to the Effective Time, and with respect to the VR 272 Repair Costs before or after the Effective Time but prior to Closing, shall be the obligation of Sellers, and Sellers shall promptly pay, or if paid by Buyer, promptly reimburse Buyer for and hold Buyer harmless from and against same. Except as otherwise provided in this Agreement (including, without limitation, Sellers’ retention of responsibility for the VR 272 Repair Costs), all costs, expenses, disbursements and obligations attributable to the Assets for periods of time from and after the Effective Time shall be the obligation of Buyer, and Buyer shall promptly pay, or if paid by Sellers, promptly reimburse Sellers for and hold Sellers harmless from and against same.

13.3 Notice to Remitters of Proceeds. Buyer shall be responsible for informing all purchasers of production or other remitters to pay Buyer and obtain from the remitter revenues accrued after the Effective Time. The remitter shall be informed by Sellers and Buyer via Letters-in-Lieu of Transfer Order or such other reasonable documents which remitter may require.

13.4 Imbalances. Set forth on Schedule 5.13 is a listing of all gas imbalance volumes derived from the most recent imbalance statement from the operator of each Well where an imbalance exists measured in MMBTUs and the aggregate net volume of over-production or under-production, as applicable, with respect to the Assets (the “Represented Imbalance”). As part of the Final Settlement Statement, the Base Purchase Price shall be adjusted, upward or downward as appropriate, to reflect the value of the difference between the Represented Imbalance and the aggregate net volume of over-production or under-production as of the Effective Time (the “Assumed Imbalance”). The value of said difference between the aggregate net volume (less royalties) of over-production or under-production, as applicable, shall be the product obtained by multiplying $3.00 by the volume of such difference in MMBTUs. Buyer shall be solely responsible for any liability and solely entitled to any benefit from such production imbalances relating to the Assets, whether occurring on, before or after the Effective Time.

ARTICLE 14

14. INTERIM OPERATIONS

14.1 Standard of Care.

Subject to the additional restrictions set forth in this Section 14.1, Sellers shall operate the Seller-operated Assets in accordance with all applicable laws, using the standard of care as an ordinarily prudent operator and consistent with past practices until Closing, or such later time as any applicable joint operating agreement may require, when such operation shall be turned over to, and become the responsibility of, Buyer. During the period from the Execution Date to Closing, Sellers shall (i) permit Buyer to have access for inspection only to those Assets operated by Seller; (ii) except for emergency action taken in the face of risk to life, property or the environment, shall not, without the prior written consent of Buyer (which shall not be unreasonably withheld) approve or authorize any AFEs or capital expenditures over One Hundred Thousand Dollars ($100,000) net to the interest of Sellers which are received by Sellers with respect to any Assets, incur costs for discretionary expenditures for operations in excess of One Hundred Thousand Dollars ($100,000) net to the interest of Sellers for which AFEs are not prepared; (iii) operate, or if Sellers are not the operator, use reasonable efforts to ensure that the operator operates the Assets in its ordinary course of business and in accordance with applicable industry standards and the terms and conditions of all applicable Contracts, laws and regulations; (iv) not transfer, sell, hypothecate, encumber, abandon or otherwise dispose of any portion of the Assets (other than the sale of Hydrocarbons in the ordinary course of business or as required in connection with the exercise by third-parties of Preferential Purchase Rights) any of the Assets; (v) assist the Buyer (without incurring any third party expenses) in preserving the present relationships related to the Assets with Persons having significant business relations therewith, such as suppliers, customers, brokers, agents or otherwise; (vi) take any and all actions necessary to ensure that the Assets are free and clear of all liens and encumbrances as of Closing; (vii) not waive, compromise or settle any material right or claim if such waiver, compromise or settlement would adversely affect the use, ownership or operation of any of the Assets in any material respect, (viii) cause the Assets to be maintained in accordance with the terms and conditions of the applicable Contracts and applicable laws and regulations and consistent with past practices, and consult with Buyer with respect to same; and (ix) on a timely basis (i.e. promptly after receipt by Seller), provide Buyer with copies of the daily operations and production reports attributable to the Seller operated Assets.

14.2 Liability of Operator. Notwithstanding Section 14.1, Sellers shall not be liable to Buyer for any claims, demands, causes of action, damages, or liabilities arising out of Sellers’ operation of the Assets after the Effective Time, insofar as Sellers continue to operate and maintain the Assets in accordance with the terms of this Agreement (including, without limitation, Section 14.1 above) and as a reasonable and prudent operator, and insofar as no such Claims, demands, causes of action,

damages, or liabilities relating to such interim operation are attributable to the gross negligence or willful misconduct of Sellers.

14.3 Removal of Signs. Buyer shall promptly, but no later than required by applicable rules and regulations or thirty (30) days thereafter, whichever is earlier, remove any signs and references to Sellers and shall erect or install all signs complying with any applicable governmental rules and regulations, including, but not limited to, those showing the Buyer as operator of the Assets.

14.4 Third-Party Notifications. Buyer shall make all notifications to all Governmental Authorities, “one call services” and similar groups associated with the operation of the Assets within ten (10) days of Closing. A copy of all such notifications shall be provided to Sellers pursuant to the notice provisions contained in Article 18 hereof.

14.5 Vermilion Block 272 Field. At least ten (10) days prior to Closing Sellers shall have successfully completed the VR 272 Repair Operations, at Sellers’ sole risk and expense, and prior to Closing the gross production levels for the Vermilion Block 272 Field shall have reached a daily production rate of not less than 2,850 bopd and 1,900 mcfpd, and a daily production rate of not greater than 3,000 bwpd. Should this not occur, Buyer shall have the recourse provided in Section 10.2(f) and the right to terminate this Agreement pursuant to Section 19.1(d).

ARTICLE 15

15. EXCHANGE PROVISION

Sellers and Buyer, respectively, shall have the right, prior to Closing, to elect to effect a tax-deferred exchange under Internal Revenue Code Section 1031 (a “Tax Deferred Exchange”) for the Assets at any time prior to Closing. If such Party elects to affect a Tax-Deferred Exchange, the other Party agrees to execute escrow instructions, documents, agreements or instruments to affect the exchange; provided, however, that the other Party shall incur no additional costs, expenses, fees or liabilities as a result of or connected with the exchange. Sellers and Buyer, as the case may be, may assign any of its rights and delegate performance of any of its duties under this Agreement in whole or in part to a third party or an affiliate in order to effect such an exchange; provided, however, that each such Sellers and/or Buyer shall remain responsible to the other Party for the full and prompt performance of its respective delegated duties. The electing Party shall indemnify and hold the other Party and its affiliates harmless from and against all claims, expenses (including reasonable attorneys’ fees), loss and liability resulting from its participation in any exchange undertaken pursuant to this Article 15 pursuant to the request of the electing Party.

Notwithstanding anything to the contrary contained herein, Sellers’ aggregate liability for the indemnification under Section 16.4(i)-(vi) above shall not exceed fifty percent (50%) of the Base Purchase Price.

16.6 Further Limitation on Indemnification. Neither Party shall have any obligation under Article 16 with respect to any amount which has already been taken into account and applied to or against the Base Purchase Price in the Closing

Settlement Statement or the Final Settlement Statement, provided such Party has paid all amounts due pursuant to this Agreement.

16.7 Indemnification Procedures

16.7.1 All claims for indemnification under this Agreement shall be asserted and resolved pursuant to this Section 16.7. Any person claiming indemnification hereunder is hereinafter referred to as the “Indemnified Party” and any person against whom such claims are asserted hereunder is hereinafter referred to as the “Indemnifying Party.”

16.7.2 In the event that a Party wishes to assert a claim for indemnity hereunder, such Party shall with reasonable promptness provide to the Indemnifying Party a written notice of the indemnity claim it wishes to assert on behalf of itself or another Indemnified Party, including the specific details of and specific basis under this Agreement for its indemnity claim (a “Claim Notice”). To the extent any Losses for which indemnification is sought are asserted against or sought to be collected from an Indemnified Party by a third party, such Claim Notice shall include a copy of all papers served on the applicable Indemnified Party with respect to such claim. The Indemnifying Party shall have thirty (30) days from the personal delivery or receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not it disputes its liability hereunder with respect to such Losses and/or (ii) with respect to any Losses arising out of, associated with, or relating to third party claims, whether or not it desires, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against any such Losses. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against such Losses, the Indemnifying Party shall have the right to defend all appropriate proceedings with counsel of its own choosing. If the Indemnified Party desires to participate in, but not control, any such defense or settlement it may do so at its sole cost and expense. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Losses that the Indemnifying Party elects to contest or, if appropriate and related to the claim in question, in making any counterclaims against the third party asserting such Losses, or any cross-complaint against any third party (other than a Seller Indemnified Party, if the Indemnified Party is a Seller Indemnified Party; and other than a Buyer Indemnified Party, if the Indemnified Party is a Buyer Indemnified Party). Such cooperation shall include the retention and provision to the Indemnifying Party of all records and other information that are reasonably relevant to the losses at issue. No third party claim that is the subject of indemnification

hereunder may be settled or otherwise compromised without the prior written consent of the Indemnifying Party. No such claim may be settled or compromised by the Indemnifying Party without the prior written consent of the Indemnified Party unless such settlement or compromise (i) entails a full and unconditional release of the Indemnified Party (and any other members of the Indemnified Party’s group, i.e., all Seller Indemnified Parties or all Buyer Indemnified Parties) without any admission or finding of fault or liability and (ii) does not impose on the Indemnified Party any material non-financial obligation or any financial obligation that is not fully paid by the Indemnifying Party.

ARTICLE 17

17. CASUALTY LOSS

If prior to Closing any of the Assets are substantially damaged or destroyed by fire or other casualty (“Casualty Defect”), Sellers shall notify Buyer promptly after Sellers learn of such event. Sellers shall have the right, but not the obligation, to cure any such Casualty Defect by repairing such damage or, in the case of Equipment, replacing the damaged Equipment with equivalent items, no later than the Closing, insofar as the same are done to Buyer’s reasonable satisfaction. If any Casualty Defect exists at Closing, at Sellers’ option, Buyer shall proceed to purchase the damaged Assets, and Buyer and Seller shall endeavor to mutually agree on the amount of the adjustment to the Base Purchase Price. If the adjustment due to the Casualty Defect is reasonably calculated to be in excess of $2,000,000 and, despite good faith efforts the Parties cannot agree on the amount of the adjustment to the Base Purchase Price, the Assets affected by the Casualty Defect shall be excluded from this transaction and the Base Purchase Price shall be reduced by the entire Allocated Value of such Assets so excluded. Notwithstanding any of the preceding provisions of this Article 17, all adjustments applicable to Casualty Defects shall be made prior to Closing. Notwithstanding anything to the contrary contained in this Article 17, Sellers shall be entitled to retain all insurance proceeds, if any, and claims against other parties relating to any such Casualty Defect. For purposes of this provision, normal wear and tear shall not be considered a Casualty Defect.

ARTICLE 18

ARTICLE 19

19. TERMINATION

19.1 Termination. This Agreement and the transactions contemplated hereby may be terminated at any time prior to the Closing:

(a) by the mutual written agreement of Buyer and Sellers;

(b) by written notice from either Buyer or Sellers if Closing has not occurred on or before July 31, 2010; provided, however, that no Party may terminate this Agreement pursuant to this Section 19.1(b) if such Party’s breach of its representations and warranties or its failure to comply with its obligations or covenants under this Agreement caused the Closing not to occur on or before this date;

(c) by written notice from either Buyer or Sellers if the aggregate sum of (i) the Title Defect amounts for all Title Defects timely and properly asserted pursuant to Article 7, (ii) the Environmental Defect amounts for all Environmental Defects timely and properly asserted pursuant to Article 8, and (ii) the Casualty Defect amounts pursuant to Article 17, exceed ten percent (10%) of the Base Purchase Price; or

(d) by written notice from Buyer if Buyer’s condition to close set forth in Section 10.2(f) has not been satisfied on or before July 8, 2010.

19.2 Liabilities Upon Termination; Deposit Amount. If this Agreement terminates, as described in Section 19.1 above, then the entire Deposit will be returned and paid to Buyer and all obligations of the Parties under this Agreement will thereafter terminate and be of no further force and effect, except that the provisions of Section 20.4 and 20.5 will survive; provided, however, that if this Agreement is terminated because of either (i) a breach of this Agreement by the Sellers or because Buyer’s conditions to Closing are not satisfied as a result of Sellers’ failure to comply with its obligations under this Agreement (and, as a result, Buyer elects to terminate this Agreement under Section 19.1(b) or Section 19.1(d) above), then Buyer shall be entitled to the immediate return of the Deposit and shall also be entitled to pursue all remedies available at law for damages or other relief, in equity or otherwise; or (ii) a breach of this Agreement by Buyer or because Sellers’ conditions to Closing are not satisfied as a result of Buyer’s failure to comply with its obligations under this Agreement (and, as a result, Sellers elect to terminate this Agreement under Section 19.1(b) above), then Sellers, as their sole remedy, shall be entitled to retain the Deposit as liquidated damages (and the parties hereby acknowledge that the extent of damages to Sellers occasioned by such breach or default or failure to proceed by Buyer would be impossible or extremely impractical to ascertain and that the Deposit is a fair and reasonable estimate of such damage).

ARTICLE 20

20. MISCELLANEOUS

20.1 Entire Agreement. This Agreement and all Exhibits attached hereto and incorporated herein constitute the entire agreement between the Parties. Any previous negotiations or communications between the Parties are merged herein.

20.2 Survival. This Agreement shall be binding upon and shall inure to the benefit of the undersigned, their successors, heirs, assigns and corporate successors and may be supplemented, altered, amended, modified, or revoked by writing only, signed by both Parties. The representations made by Sellers and Buyer under Articles 5 and 6 shall continue in full force and effect for a period of one (1) year from and after the Closing Date. All other representations, promises, agreements, releases, and indemnities made in this Agreement or in the Conveyances shall survive Closing.

20.3 Arbitration. All disputes arising out of, or in connection with, this Agreement or any determination required to be made by Buyer and Sellers as to which the parties cannot reach an agreement shall be settled by arbitration in Houston, Texas. Any matter to be submitted to arbitration shall be determined by a panel of three (3) arbitrators, unless otherwise agreed by the Parties. Each arbitrator shall be a person experienced in both the oil and gas industry and the subject matter of the dispute and shall be appointed:

(a) by mutual agreement of Buyer and Sellers, or

(b) failing such agreement, within sixty (60) days of the request for arbitration, each Party shall appoint one arbitrator, and the third arbitrator shall be appointed by the other two arbitrators, or, if they cannot agree, by a Judge of the United States District Court, Southern District of Texas, Fifth Circuit.

In the event of the failure of refusal of the Parties to appoint the arbitrator(s) within one hundred twenty (120) days of the request for arbitration, the arbitrator remaining to be named shall be selected in accordance with the Rules of the American Arbitration Association. The arbitration shall be conducted in accordance with reasonable rules established by the arbitrators. Any award by the arbitrator shall be final, binding and non-appealable, and judgment may be entered thereon in any court of competent jurisdiction.

20.4 Confidentiality Agreement. The Parties understand and agree that the terms and provisions of that certain Confidentiality Agreement dated April 6, 2010 by and between Sellers and Buyer (the “Confidentiality Agreement”) shall remain in full force and effect until the Closing of this transaction. In the event of termination of this Agreement pursuant to Article 19, the Buyer agrees to keep all of the terms of this transaction confidential for a period equal to the later of the date of termination of the Confidentiality Agreement or two (2) years following termination of this Agreement. Furthermore, any additional information obtained as a result of Buyer’s access to the Assets which does not specifically relate to the Assets shall continue to be treated as confidential for a period of two (2) years following the date of this Agreement and shall not be disclosed by the Buyer without the prior written consent of the Sellers. The above restrictions on disclosure and use of information obtained pursuant to this Agreement shall not apply to information to the extent it:

(a) is or becomes publicly available through no act or omission of the Buyer or any of its consultants or advisors; or

(b) is subsequently obtained lawfully from a third party, where the Buyer has made reasonable efforts to insure that such third party is not a party to or bound by any confidentiality agreement with the Sellers; or

If the Buyer employs consultants, advisors or agents to assist in its review of the Assets, Buyer shall be responsible to Sellers for ensuring that such consultants, advisors and agents comply with the restrictions on the use and disclosure of information set forth in this Section 20.4.

20.5 Choice of Law. THIS AGREEMENT AND ITS PERFORMANCE SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF TEXAS.

20.6 Assignment. The rights and obligations under this Agreement may not be assigned by any Party without the prior written consent of the other Party.

20.7 No Admissions. Neither this Agreement, nor any part hereof, nor any performance under this Agreement shall constitute or be construed as a finding, evidence of, or an admission or acknowledgment of any liability, fault, or past or present wrongdoing, or violation of any law, rule, regulation, or policy, by either Sellers or Buyer or by their respective officers, directors, employees, or agents.

20.8 Amendments. Except for waivers specifically provided for in this Agreement, this Agreement may not be amended nor any rights hereunder waived except by an instrument in writing signed by the Party to be charged with such amendment or waiver and delivered by such Party to the other Party claiming the benefit of such amendment or waiver.

20.9 Counterparts. This Agreement may be executed by Buyer and Sellers in any number of counterparts, each of which shall be deemed an original instrument, but all of which together shall constitute one and the same instrument. Execution can be evidenced by facsimile transmission of signatures pages with original signature pages to promptly follow in due course.

20.10 Third-Party Beneficiaries. Neither this Agreement nor any performances hereunder by Sellers or Buyer shall create any right, claim, cause of action, or remedy on behalf of any person not a party hereto.

20.11 Public Communications. After Closing, either Party may make a press release or public communication concerning this transaction; provided, however, any such press release or public communication is subject to the other Party’s prior review and written approval, which approval will not be unreasonably withheld; provided further, however, that; if Buyer, on the one hand, or Sellers, on the other is required by law or the rules of the New York Stock Exchange to make such public announcement or statement, then the same may be made without the approval of the other Parties, but only to the extent the name of Sellers is omitted from such announcement or statement.

20.12 Headings. The headings of the Articles and Sections of this Agreement are for guidance and convenience of reference only and shall not limit or otherwise affect any of the terms or provisions of this Agreement.

20.13 Expenses. Each of the Parties hereto shall pay its own fees and expenses incident to the negotiation and preparation of this Agreement and consummation of the transactions contemplated hereby, including brokers’ fees. Buyer shall be responsible for the cost of all fees for the recording of the Conveyances relating to the Assets. All other costs shall be borne by the Party incurring them.

20.14 Waiver of Consumer and Other Rights. Sellers and Buyer intend that Buyer’s rights and remedies with respect to the transaction contemplated by this Agreement and with respect to all acts or practices of Sellers, past, present or

future, in connection with the transaction contemplated by this Agreement shall be governed by legal principles other than the Texas Deceptive Trade Practices Consumer Protection Act, Tex. Bus. & Corn. Code Xxx. §17.41, et seq. (Xxxxxx 1987) (the “DTPA”) or similar laws in other states. BUYER WAIVES IT RIGHTS UNDER THE DTPA SPECIFICALLY INCLUDING SECTION 17.41 ET. SEQ., VERNON’S TEXAS CODE ANNOTATED, BUSINESS AND COMMERCE, A LAW THAT GIVES CONSUMERS SPECIAL RIGHTS AND PROTECTIONS, OR ANY SIMILAR STATE OR FEDERAL LAW. AFTER AN OPPORTUNITY TO CONSULT WITH AN ATTORNEY OF ITS OWN SELECTION, BUYER ACKNOWLEDGES THAT THE DISCLAIMERS AND WAIVERS GIVEN IN AND UNDER THIS AGREEMENT SHALL BE CONSIDERED MATERIAL AND INTEGRAL PARTS OF THIS AGREEMENT, WITH CONSIDERATION GIVEN THEREFORE, AND ACKNOWLEDGES THAT ALL DISCLAIMERS AND WAIVERS ARE “CONSPICUOUS” AND HAVE BEEN BROUGHT TO THE ATTENTION OF BUYER, AND THAT BUYER HAS VOLUNTARILY AND KNOWINGLY CONSENTED TO ALL DISCLAIMERS AND WAIVERS. Buyer hereby warrants and represents to Sellers, as of the date hereof and as of the Closing Date, that (i) Buyer is not in a significantly disparate bargaining position, (ii) Buyer has been represented by legal counsel in connection with the transaction contemplated by this Agreement, which transaction does not involve the purchase or lease of a family residence occupied or to be occupied as a residence, and which transaction is for a consideration paid or to be paid that exceeds $500,000.00 and (iii) Buyer is a business consumer with assets of $5,000,000.00 or more according to Buyer’s most recent financial statement prepared in accordance with GAAP and has knowledge and experience in financial and business matters that enable Buyer to evaluate the merits and risks of the transaction. Buyer acknowledges that the Purchase Price is predicated upon this waiver of the DTPA and similar laws in other states and the inapplicability of the DTPA and similar laws in other states and Buyer’s representations and warranties contained in this Section 20.14, and the Sellers, in determining to proceed with entering into this Agreement, have expressly relied upon this waiver and the inapplicability of the DTPA and similar laws in other states and Buyer’s representations and warranties contained in this Section 20.14.

IN WITNESS WHEREOF, the parties have executed this Agreement on the date first written above.
