Upon the execution of this Agreement, Buyer shall pay to Seller an earnest money deposit in the amount of Twenty Million and 00/100 United States Dollars (US $20,000,000.00) ("Earnest Money"). In the event of Closing, Buyer shall receive a credit toward the Purchase Price equal to the amount of the Earnest Money (plus Computed Interest on the Earnest Money from the date of receipt by Seller until August 2, 2004). If Closing does not occur, the provisions of Article 13.2 shall apply.

Allocation.

In the event the Partnership is in a net overproduced position as of the Effective Time, the Purchase Price will be adjusted downward by an amount equal to the net overproduced quantity multiplied by the average gas price received by Seller for the net revenue share of gas sold from the portion of the Properties in the county where the imbalance property is located during the month immediately preceding the Effective Time (net of all allowable taxes and deductions) on an MMBtu basis. In the event the Partnership is in a net underproduced position at the various wellhead or initial delivery points as of the Effective Time, the Purchase Price shall be increased by an amount equal to the net underproduced quantity multiplied by the average price received by the Partnership for the net revenue share of gas sold from the portion of the Properties in the county where the imbalance property is located during the month immediately preceding the Effective Time (net of all allowable taxes and deductions) on an MMBtu basis.

The general partner of the Partnership, who Seller represents and warrants also serves as the duly-appointed tax matters partner under Section 6231 of the Code shall cause the Partnership to duly elect in a timely manner, pursuant to Section 754 of the Code and the corresponding provisions of applicable state law, to adjust the basis of the Partnership 's assets as provided in Sections 734 and 743 of the Code, as of the Closing and with respect to the portion of the tax year for which Agent served as General Partner of the Partnership.

DUE DILIGENCE REVIEW

Review of Records. The Partnership and Seller shall make available to Buyer, during normal business hours, and if required by Buyer during evening hours and on weekends, original Records in the Partnership's or Seller's possession relating to the Properties including, without limitation, all Records relating to title. Buyer shall be entitled to review the Records. Buyer shall have the right to reasonably request copies of any and all such Records at Buyer's expense.

Alleged Title Defects.

As soon as reasonably practicable after Buyer's review of the title Records, but in no event later than 4:00 p.m. on July 28, 2004, Buyer shall deliver a written notice to Seller of any Alleged Title Defects identifying any Properties which are subject to Alleged Title Defects with an estimated value in excess of Ten Thousand Dollars ($10,000.00) per Alleged Title Defect. Buyer shall endeavor to keep Seller advised on a current basis of any Alleged Title Defects as any are identified during Buyer's due diligence review. Buyer's notice of Alleged Title Defects shall include a complete description (including any supporting documentation in Buyer's possession) of each Alleged Title Defect being claimed and a value which Buyer attributes to each said Alleged Title Defect.

With respect to Alleged Title Defects that are not disputed in good faith by Seller, Seller shall, and shall cause the Partnership to, use commercially reasonable efforts to cure, prior to the scheduled Closing Date, at Seller's sole cost and expense, the Alleged Title Defects selected by Seller that exceed the Title Defect Threshold Amount. Immediately prior to the scheduled Closing Date, Buyer and Seller shall meet in an attempt to mutually agree on a proposed resolution with respect to any Alleged Title Defects which by such time have not been agreed to or resolved between the parties.

If as of the scheduled Closing Date there are Open Title Defects that Seller is obligated to use commercially reasonable efforts to cure under Article 4.2(b), Buyer shall have the right to either (i) provide written notice of its election to refer any such Open Title Defect to binding resolution before an attorney licensed in the state where the affected portion of the Properties is located who is familiar with the types of leases or properties involved in or affected by the Open Title Defect and who has at least fifteen (15) years of oil and gas title experience and satisfies the independence and neutrality standards set forth in Article 15.16(b); or (ii) deliver written notice to Seller that the spacing unit identified as being subject to the Open Title Defect shall be reconveyed by the Partnership to Seller and the Purchase Price for the Partnership shall be reduced by the value allocated to such spacing unit.

Notwithstanding Seller's obligations under Article 4.2(b), Seller shall have the right to request and receive a reassignment of one or more spacing units identified as being subject to the Open Title Defect and the Purchase Price shall be reduced by the value allocated to such spacing units, until such time as the aggregate reduction in the Purchase Price on account of exclusion of spacing units at Seller's direction has reached one percent (1%) of the Purchase Price. If Seller requests a reassignment of a spacing unit, Buyer shall have the right to waive the Open Title Defect in which case the spacing unit will not be excluded, the Purchase Price will not be reduced and the parties shall proceed to Closing.

If the dispute is referred to binding resolution, the title attorney shall resolve the Open Title Defects submitted by the parties in accordance with the procedure set forth in Article 15.16(c). If the parties are not able to agree on a title attorney, the Designating Entity (as defined in Article 15.16(a)) shall appoint the title attorney. The decision of the title attorney regarding any Open Title Defect shall be final as between the parties.

Preferential Purchase Rights and Consents.

Preferential Purchase Rights. Promptly after execution of this Agreement, Seller shall, and shall cause the Partnership, to provide notice to all holders of preferential rights to purchase all or any portion of the Properties in accordance with the terms of such preferential rights to the extent any such rights may apply to the sale of the Partnership; provided, however, Seller agrees to provide all such notices as would be required if Seller was selling the Properties to an unaffiliated third party. If, prior to Closing, a holder of a preferential purchase right relating to any part of the Properties notifies the Partnership or Seller that it intends to exercise its rights with respect to any of the Properties to which its preferential purchase right applies, the Properties covered by said preferential purchase right shall be excluded from the Properties owned by the Partnership at Closing of the sale of the Partnership Interests to Buyer, and the Purchase Price shall be reduced by the value allocated to said Properties as set forth on Exhibit A-1. If the holder of the preferential purchase right fails to consummate the purchase of the Properties, Seller shall promptly notify Buyer. Within ten (10) Business Days after Buyer's receipt of such notice or the Closing, whichever is later, Seller shall sell to Buyer, and Buyer shall purchase from Seller, such Properties under the terms of this Agreement for a price equal to the value allocated to such Properties, subject to any adjustment provided for in this Agreement. Notwithstanding the foregoing, Buyer shall not have any obligation to purchase such Properties if Buyer is not notified in writing of the preferential purchase right holder's failure to consummate the purchase of such Properties within thirty (30) Days following Closing.

Consents. Promptly after execution of this Agreement, Seller shall, and shall cause the Partnership, to provide notice to all third parties who have the right to consent to the assignment of all or any portion of the Properties ("Required Consents") in accordance with the terms of such Required Consents to the extent any such rights may apply to the sale of the Partnership; provided, however, Seller agrees to provide all such notices as would be required if Seller was selling the Properties to an unaffiliated third party. If, prior to Closing, any such Required Consent is not obtained, the Properties covered by such Required Consent shall be excluded from the Properties owned by the Partnership at Closing of the sale of the Partnership Interests to Buyer, and the Purchase Price shall be reduced by the value allocated to said Properties as set forth on Exhibit A-1. If Seller subsequently obtains any such Required Consent, Seller shall promptly notify Buyer. Within ten (10) Business Days after Buyer's receipt of such notice or the Closing, whichever is later, Seller shall sell to Buyer, and Buyer shall purchase from Seller, such Properties under the terms of this Agreement for a price equal to the value allocated to such Properties, subject to any adjustment provided for in this Agreement. Notwithstanding the foregoing, Buyer shall not have any obligation to purchase such Properties if Buyer is not notified in writing of the receipt of such Required Consent within thirty (30) Days following Closing.

Environmental Inspection. Upon execution of this Agreement, the Partnership and Seller shall grant Buyer access to the Properties, for the purpose of inspecting, examining, investigating and assessing the physical and environmental condition of the same. Buyer shall have the right, where authorized by the Partnership or Seller (which authorization shall not be unreasonably withheld), to conduct tests related to the physical and environmental condition of the Properties, so long as such tests do not unreasonably interfere with the operation of the Properties. Buyer's access to the Properties shall be at Buyer's sole risk, cost and expense, and Buyer shall release Seller and other working interest owners of the Properties from and shall fully protect, indemnify and defend the Partnership and Seller and the other Working Interest owners of the Properties and their respective officers, agents, employees and Affiliates and hold them harmless from and against any and all Claims resulting from Buyer's acts or negligent omissions in the exercise of its rights under this Article 4.4, including, without limitation, Claims relating to (a) injury or death of any person or persons whomsoever, (b) damage to or loss of any property or resource, (c) pollution, environmental damage or violation of Environmental Laws, (d) common law causes of action such as negligence, gross negligence, strict liability, nuisance or trespass, or (e) fault imposed by statute, rule, regulation or otherwise. The indemnity obligation and release provided herein shall not apply in the event of any negligent acts or omissions of representatives of the Partnership, Seller or other working interest owners of the Properties and/or their respective officers, agents, employees and Affiliates that occurred during Buyer's exercise of its rights under this Article 4.4. Buyer additionally agrees to comply with the reasonable rules, procedures and instructions issued by the Partnership, Seller or any Third Party operator of the Properties while upon the Properties.

Alleged Environmental Conditions.

As soon as reasonably practical after Buyer's review of the environmental condition of the Properties, but in no event later than July 28, 2004, Buyer shall deliver a written notice to Seller of any Alleged Environmental Conditions identifying any Properties which are subject to Alleged Environmental Conditions with an estimated remediation cost in excess of Ten Thousand Dollars ($10,000.00) per Alleged Environmental Condition. Buyer shall endeavor to keep the Partnership and Seller advised on a current basis of any Alleged Environmental Condition as any are identified during Buyer's due diligence review. Buyer's notice of Alleged Environmental Conditions shall include a complete description of each individual environmental condition which Buyer takes exception to (including any supporting documentation in Buyer's possession) and the costs which Buyer in good faith attributes to remediating the same.

With respect to all Alleged Environmental Conditions that are not disputed in good faith by the Partnership or Seller, Seller shall cause the Partnership to use commercially reasonable efforts to cure prior to the scheduled Closing Date, at Seller's sole cost and expense, the Alleged Environmental Conditions selected by Seller that exceed the Environmental Defect Threshold Amount. Immediately prior to the scheduled Closing Date, Buyer and Seller shall meet in an attempt to mutually agree on an acceptable resolution addressing any Alleged Environmental Conditions which by such time have not been agreed to or resolved by the parties.

If as of the scheduled Closing Date there are Open Environmental Conditions that Seller is obligated to use commercially reasonable efforts to cure under Article 4.5(b), Buyer shall have the right to either (i) provide written notice of its election to refer any such Alleged Environmental Condition to binding resolution before an attorney or environmental engineering firm licensed in the state where the affected portion of the Properties is located, who is familiar with Environmental Laws, who has at least fifteen (15) years of Environmental Laws experience and satisfies the independence and neutrality standards set forth in Article 15.16(b); or (ii) deliver written notice to Seller that the spacing unit identified as being subject to the Open Environmental Defect shall be reconveyed by the Partnership to Seller and the Purchase Price for the Partnership shall be reduced by the value allocated to the affected spacing unit. In any such event, Closing shall proceed as to the purchase of the Partnership in accordance with Article 4.6(c). If the dispute is referred to binding resolution, the environmental engineer or attorney shall resolve all Open Environmental Defects submitted by the Parties in accordance with the procedure set forth in Article 15.16(c). If the parties are not able to agree on an environmental attorney or engineer, the Designating Entity (as defined in Article 15.16(a)) shall appoint the environmental attorney or engineer. The decision of the environmental attorney or engineer regarding any Alleged Environmental Condition shall be final as between the parties.

Defect Curative Procedures. Schedule 4.6 to this Agreement sets forth the procedures to be followed by the parties with respect to Alleged Title Defects, Alleged Environmental Conditions and Open Defects. All references to a sub-article of this Article 4.6 refer to the applicable sub-article in Schedule 4.6.

ACCOUNTING

Revenues, Expenses and Capital Expenditures. All revenues attributable to the operation of the Properties prior to the Effective Time shall be owned by and for the account of Seller. Seller shall be entitled to all revenues and shall be responsible for all costs and expenses and related accounts payable attributable to the ownership or operation of the Properties, in each case to the extent they relate to the time prior to the Effective Time. All revenues attributable to the operation of the Properties after the Effective Time shall be owned by and for the account of Buyer. The Partnership, after acquired by Buyer, shall be entitled to all revenues and shall be responsible for the payment of all costs and expenses and related accounts payable attributable to the ownership or operation of the Properties, in each case to the extent they relate to the time after the Effective Time. The actual amounts or values associated with the above shall be accounted for to the extent known in the Closing Statement with the final reconciliation contained in the Final Accounting Settlement.

Buyer shall succeed to all deposits paid to the Minerals Management Service or to the State of New Mexico associated with the Properties as of the Effective Time. The deposits shall be reflected as a Purchase Price increase in the Closing Statement. At Closing, Buyer shall succeed to such deposits referenced above.

Notwithstanding the above provision, Buyer acknowledges that the Partnership is currently engaged in a development drilling program on the Properties and that the operations listed on Schedule 9.9 shall continue in the ordinary course of business. With respect to the ongoing operations listed on Schedule 9.9, Seller, as owner of the Partnership, shall bear the actual cost of such operations and installation of the equipment specified until Closing. If such operations have not been completed as of Closing, the Purchase Price shall be reduced by the estimated cost to perform and complete such operations and to install the specified equipment based on the cost to Seller of comparable operations or equipment, subject to reconciliation to the extent known in the Final Accounting Settlement. With respect to any capital expenditures or new operations conducted prior to Closing that are not listed on Schedule 9.9, subject to Seller obtaining Buyer's consent with respect thereto as required pursuant to this Agreement, Buyer shall reimburse Seller at Closing, in addition to payment of the Purchase Price, for all actual costs incurred and paid or payable by Seller, as owner of the Partnership, through the Closing in connection with such operations (including reimbursement for operator's overhead as provided in the applicable operating agreements and payments or prepayments made for equipment ordered for those operations). At Closing, Buyer shall be deemed to have assumed all liabilities and obligations relating to the ongoing operations on the Properties as of the Effective Time.

Tax Obligations. All Taxes attributable to the Partnership, each of the Sellers, or the ownership or operation of the Properties that accrue with respect to Tax periods ending at or prior to the Effective Time shall remain Seller's responsibility, and all deductions, credits and refunds pertaining to such Taxes, no matter when claimed or received, shall belong to Seller. All Taxes attributable to the Partnership or the ownership or operation of the Properties accruing or becoming due after, and with respect to Tax periods beginning at or after, the Effective Time (excluding franchise and income taxes of the Partnership and the Sellers with respect to the periods beginning at the Effective Time and ending at the Closing) shall be Buyer's responsibility, and all deductions, credits and refunds pertaining to such Taxes, no matter when claimed or received, shall belong to Buyer. The actual amounts or values associated with the above, if any, shall be accounted for to the extent known in the Closing Statement and finally reconciled in the Final Accounting Settlement. Taxes on real and personal property with respect to the Properties which have not been assessed and paid for calendar year 2004 by the Effective Time shall be estimated based on the prior year assessment, prorated through the Effective Time and reflected in the Closing Statement as a reduction in the Purchase Price; provided, however, within thirty (30) Days after the actual ad valorem tax liability for the 2004 calendar year is known, Buyer and Seller shall make such payments or credits between themselves as are necessary so that each party bears only its pro-rata portion of the actual 2004 ad valorem tax liability. The parties agree that the transactions contemplated herein will constitute the sale and purchase of all the ownership interests in a limited partnership by Seller. Accordingly, the parties will take commercially reasonable actions to establish and claim any available exemption from any Transfer Taxes that might otherwise be associated with the transactions contemplated herein. Notwithstanding the foregoing, although the parties have concluded that no Transfer Taxes are or will become due as a result of the transactions contemplated by this Agreement, Buyer shall be solely responsible for any such Transfer Taxes as and when the same shall, if ever, become due; and further provided that Sellers shall notify Buyer in writing promptly upon receipt of any notice or knowledge of any inquiry or demand from any taxing authority or its agent with respect to such Transfer Taxes and shall not pay same, offer to pay same, or concede that any such Transfer Taxes are due, but shall instead cooperate with Buyer and its advisers in any effort to determine that such Transfer Taxes are not legally due, or in seeking an exemption therefrom.

Obligations and Credits. All prepaid utility charges, Taxes, rentals and any other prepaids other than insurance premiums applicable to periods of time after the Effective Time, if any, and attributable to the Properties shall be reimbursed to Seller by Buyer; and accrued payables applicable to periods of time prior to the Effective Time, if any, and attributable to the Properties shall be the responsibility of Seller. The actual amounts or values associated with the above shall be accounted for in the Closing Statement and the Final Accounting Settlement.

Miscellaneous Accounting. In addition to the items set forth in Articles 5.1 through 5.3, any other amounts due between Buyer and Seller related to the ownership or operation of the Properties shall be accounted for in the Final Accounting Settlement.

Final Accounting Settlement. As soon as reasonably practicable, but in no event later than ninety (90) Days after Closing, Seller shall deliver to Buyer a post-closing statement setting forth a detailed final calculation of all post-closing adjustments applicable to the periods before and after the Effective Time ("Final Accounting Settlement"). As soon as reasonably practicable, but in no event later than thirty (30) Days after Buyer receives the post-closing statement, Buyer shall deliver to Seller a written report containing any changes Buyer proposes to be made to such statement. If Buyer fails to deliver a report to Seller containing changes Buyer proposes to be made to the post-closing statement, the post-closing statement delivered by Seller shall be deemed to be true and correct and binding on and non-appealable by the parties. As soon as reasonably practicable, but in no event later than fifteen (15) Days after Seller receives Buyer's proposed changes to the post-closing statement, the parties shall meet and undertake to agree on the final post-closing adjustments. If the parties fail to agree on the final post-closing adjustments within such fifteen (15) Day period, the disputed items shall be resolved by submitting the same to a firm of independent nationally recognized accountants mutually acceptable to the parties (the "Accounting Referee"). The Accounting Referee shall resolve the disputes regarding the Final Accounting Settlement within thirty (30) Days after having the relevant materials submitted for review. The decision of the Accounting Referee shall be binding and non-appealable by the parties. The fees and expenses associated with the Accounting Referee shall be borne equally by Buyer and Seller. The date upon which all amounts associated with the Final Accounting Settlement are agreed to by the parties, whether by decision of the Accounting Referee or otherwise, shall be herein called the "Final Settlement Date." Any amounts owed by either party to the other as a result of such final post-closing adjustments shall be paid within five (5) Business Days after the Final Settlement Date.

Post-Final Accounting Settlement. Any revenues received or costs and expenses paid by Buyer after the Final Accounting Settlement which are attributable to the ownership or operation of the Properties prior to the Effective Time shall be billed or reimbursed to Seller, as appropriate. Any revenues received or costs and expenses paid by Seller after the Final Accounting Settlement which are attributable to the ownership or operation of the Properties after the Effective Time shall be reimbursed or billed to the Partnership owned by Buyer, as appropriate.

Accounting Standard. All statements and allocations, including the Final Accounting Statement, shall be prepared in a manner consistent with the accounting practices commonly used in the oil and gas producing industry on an accrual basis.

Audit Rights. In order to verify the information provided by the parties under this Article 5, Buyer and Seller shall each have the right to conduct, at such party's sole expense, an audit of the other party's records relating thereto during the time periods specified in Article 5.5 relating to preparation and review of the Final Accounting Statement.

Transition Services. At Buyer's option, for a period of up to ninety (90) Days after Closing, as desired by Buyer, Seller agrees to provide personnel and services necessary in Seller's offices or to be available to Buyer on reasonable advance notice to assist with the cost accounting, revenue accounting and revenue disbursement relating to the Properties to facilitate an orderly transition of these functions from Seller to Buyer. Buyer shall pay Seller a monthly overhead fee in the amount of Ten Thousand Dollars ($10,000.00) per month for such transition services payable monthly in advance with the first payment due at Closing.

CASUALTY AND CONDEMNATION

Casualty and Condemnation. If any part of the Properties shall (a) be destroyed prior to Closing by a Casualty Loss or (b) be taken in condemnation or if proceedings for such purposes shall be pending; Seller shall promptly notify Buyer in writing of the nature and extent of the Casualty Loss or taking. If the value of the Casualty Loss or taking, when added to the value of all Open Defects, exceeds ten percent (10%) of the Purchase Price, then either Buyer or Seller may terminate this Agreement prior to the Closing. If either party terminates this Agreement in accordance with this Article, neither party shall have any further obligations, except as expressly provided in this Agreement, and Seller shall return to Buyer the Earnest Money plus accrued Computed Interest. If neither party terminates this Agreement, this Agreement shall remain in full force and effect, and Seller and Buyer shall agree on a reduction in the Purchase Price equal to the amount, if any, by which (i) the reduction in the value of the Properties affected by all such Casualty Losses and/or taking based on the cost to repair the Casualty Loss or the value for the affected well or property shown on Exhibit A-1 exceeds (ii) Two Hundred Fifty Thousand and 00/100 Dollars ($250,000.00); provided, however, if the parties can not agree upon any such reduction in the Purchase Price prior to the Closing, then the Purchase Price payable at Closing shall be reduced by the amount, if any, by which (i) the value of all such Casualty Loss or takings as asserted by Buyer exceeds (ii) Two Hundred Fifty Thousand and 00/100 Dollars ($250,000.00), and the dispute shall be resolved pursuant to the arbitration procedures set forth in Article 15.16 hereof. Seller shall retain any and all sums paid to Seller, unpaid awards, insurance proceeds and other payments associated with or attributable to any such Casualty Loss or taking.

Arbitration.

Any dispute arising under this Agreement ("Arbitrable Dispute") shall be referred to and resolved by binding arbitration in Houston, Texas, by three (3) arbitrators, using the Commercial Arbitration Rules of the American Arbitration Association ("AAA"), but not using the offices or auspices of the AAA; and, to the maximum extent applicable, the Federal Arbitration Act (Title 9 of the United States Code). If there is any inconsistency between this Article and any statute or rules, this Article shall control. Arbitration shall be initiated within the applicable time limits set forth in this Agreement and not thereafter or if no time limit is given, within the time period allowed by the applicable statute of limitations, by one party ("Claimant") giving written notice to the other party ("Respondent") that the Claimant elects to refer the Arbitrable Dispute to arbitration and that the Claimant has appointed an arbitrator, who shall be identified in such notice. The Respondent shall notify the Claimant within thirty (30) Days after receipt of Claimant's notice, identifying the arbitrator the Respondent has appointed. The two (2) arbitrators so chosen shall select a third arbitrator within thirty (30) Days after the second arbitrator has been appointed (upon failure of a party to act within the time specified for naming an arbitrator, such arbitrator shall be appointed by the presiding Federal District Judge for the Southern District of Texas, or if such judge refuses to act, then such arbitrator shall be selected in accordance with the Commercial Arbitration Rules of the AAA (such judge or the AAA, as the case may be, the "Designating Entity")). Seller shall pay the compensation and expenses of the arbitrator named by or for it, Buyer shall pay the compensation and expenses of the arbitrator named by or for it, and Seller and Buyer shall each pay one-half of the compensation and expenses of the third arbitrator.

Each arbitrator must be a neutral party who has never been an officer, director or employee of the parties or any of their Affiliates or any entity in which a party owns or controls more than a ten percent (10%) interest, has not provided professional or consulting services for either party within the five (5) years preceding the commencement of the proceedings, has more than ten (10) years experience in the oil and gas industry, and must have a formal financial/accounting, engineering or legal education. The hearing shall be commenced within thirty (30) Days after the selection of the third arbitrator. The parties and the arbitrators shall proceed diligently in accordance with the procedures set forth in Article 15.16(c) in order that the arbitral award shall be made as promptly as possible. The interpretation, construction and effect of this Agreement shall be governed by the Laws of Texas, and to the maximum extent allowed by law, in all arbitration proceedings the Laws of Texas shall be applied, without regard to any conflicts of laws principles. All statutes of limitation and of repose that would otherwise be applicable shall apply to any arbitration proceeding. The tribunal shall not have the authority to grant or award indirect or consequential damages, punitive damages or exemplary damages.

With respect to any Arbitrable Dispute submitted to a three person arbitration panel pursuant to this Agreement or with respect to any Open Defect submitted to a single arbitrator pursuant to either Article 4.2 or Article 4.5 of this Agreement, the following procedure shall be followed by the arbitrator(s). After submission of evidence or statements of the parties as requested by the arbitrator(s), the arbitrator(s) shall determine initially if the Claim submitted as an Arbitrable Dispute is valid or whether the Open Defect is in fact and in law a Title Defect or an Environmental Condition that warrants a Purchase Price adjustment in accordance with the terms of this Agreement. If the arbitration panel determines that an Arbitrable Dispute does not present a valid Claim, the panel shall deny the Claim and no damages shall be awarded. If the single arbitrator determines that the Open Defect is in fact and in law not a Title Defect or an Environmental Condition as defined in this Agreement, the arbitrator shall issue a written order stating that no defect condition exists. In that event, if the Open Defect was an Alleged Title Defect, the Buyer shall pay to Seller the amount by which the Purchase Price was reduced at Closing on account of such Alleged Title Defect. If the Open Defect was an Alleged Environmental Condition, the Buyer shall pay to Seller the amount by which the Purchase Price was reduced at Closing on account of such Alleged Environmental Condition.

If, as a result of the initial decision making process, the arbitration panel determines that a valid Claim was presented as an Arbitrable Dispute or that in fact and in law an Open Defect submitted to the single arbitrator does constitute a Title Defect or Environmental Condition, the arbitration hearing shall be scheduled and conducted as promptly as possible in Houston, Texas. The amount of the award relating to the Claim shall be determined by the majority vote of the three (3) arbitrators or by the single arbitrator, if applicable. The arbitration panel and the arbitrator shall have the authority to award attorney's fees and costs of arbitration to the prevailing party if the panel or the arbitrator determines that the non-prevailing party's position was not based on a commercially reasonable interpretation of the applicable standards, law or facts.

Execution in Counterparts. This Agreement may be executed in counterparts, which shall when taken together constitute one (1) valid and binding agreement. Facsimile signatures shall be effective and binding on all parties. Counterpart originals of all signatures provided by facsimile shall be provided to all parties within ten (10) Days after execution of this Agreement.
