2.4. Adjustments to Purchase Price.

(a) To determine the Closing Purchase Price, the Purchase Price shall be increased by the following amounts:

(i) the amount of all (1) ad valorem, property or similar Taxes paid by Seller and relating to the Assets for periods from and after the Effective Time, calculated in a similar fashion as set forth in Section 2.4(b)(i), and (2) any other expenses paid by Seller and relating to the Assets for periods from and after the Effective Time and properly incurred under Section 5.1;

(ii) a monthly general administration fee in the amount of $25,000 per month for each month from the Effective Date until the Closing; provided that such fee shall be prorated for any partial month between the Effective Date and the Closing based on the number of days in such month;

(iii) the aggregate amount of any and all operating costs paid by Seller, not in violation of Section 5.1, that relate to the Assets for periods from and after the Effective Time (excluding amounts for which the Purchase Price is increased pursuant to Section 2.4(a)(i) above), including, but not limited to, lease operating expenses, transportation and marketing expenses, lease payments, severance Taxes and producing overhead rates;

(iv) the aggregate amount of any and all capital expenditures actually made by Seller or on Seller’s behalf, not in violation of Section 5.1, that relate to the Assets for periods from and after the Effective Time;

(vi) an amount of money equal to any payment made by Seller prior to the Closing pursuant to the expiration of any of the xxxxxx set forth on Schedule 5.7; and

(vii) any other amount agreed upon by the parties in writing.

(b) To determine the Closing Purchase Price, the Purchase Price shall be decreased, without duplication, by the following amounts:

Such Taxes with respect to a period which the Effective Time splits shall be prorated based on the number of days in such period which fall on each side of the Effective Time; provided, however, to the extent that such Taxes are computed based on the production from the Assets, such Taxes shall be prorated between the parties based on the period in which such production which is the basis for such calculation occurs, in the same manner as the parties are entitled to receive (or be credited with) such production pursuant to the terms hereof;

(ii) amounts equal to all revenues (net of royalty, overriding royalty payments and similar such payments) collected by Seller that are attributable to production of oil or gas from the Assets (but not taking into account any xxxxxx) and from the disposal of salt water and relating to periods of time from and after the Effective Time;

(iii) an amount equal to the amount of accrued suspense funds as of the Closing Date (such amount to be determined by Seller by updating the amount of accrued suspense funds as of November 30, 2008 set forth on Schedule 2.4(b)(iii) to reflect the amount of accrued suspense funds as of the Closing Date;

(iv) an amount, calculated in accordance with the procedures of Exhibit A for Title Defects and Environmental Defects, equal to the agreed value of any Title Defect or Environmental Defect that is asserted prior to Closing, agreed to by Seller, and remains uncured by Seller at Closing; provided that Title Defects or Environmental Defects for which there is no agreement prior to Closing shall be addressed in accordance with procedures of Exhibit A;

(v) an amount of money equal to the Allocated Value of any Leases or Xxxxx set forth on Schedule 3.4(b) that are removed from the purchase and sale under this Agreement by reason of the exercise of a preferential right to purchase by the holder of such right prior to Closing;

(vi) an amount of money equal to any payment received by Seller prior to the Closing pursuant to the expiration of any of the xxxxxx set forth on Schedule 5.7; and

(vii) any other amount agreed upon by the parties in writing.

2.5. Determination of Purchase Price.

(a) The Closing Purchase Price shall be determined by adding to or subtracting from the Purchase Price, as applicable, each adjustment to be made to the Purchase Price at Closing pursuant to Sections 2.3 and 2.4, as proposed by Seller and not disputed by Buyer in accordance with this Section 2.5.

(b) Seller shall prepare and deliver to Buyer at least five Business Days before the Closing Date a statement (the “Preliminary Settlement Statement”) setting forth Seller’s good faith estimate of each adjustment (including the calculation thereof) to be made in accordance with Sections 2.3 and 2.4. Buyer may dispute in good faith Seller’s estimate of the amount of such adjustments by delivery to Seller by written notice thereof within two Business Days after receipt of such estimate. Buyer and Seller shall use commercially reasonable efforts to resolve any such dispute in writing prior to Closing. If any such disputed amounts are not resolved by mutual written agreement of Buyer and Seller prior to Closing, (i) such disputed amounts shall be resolved in accordance with Section 2.5(c)(i) and (ii) Closing shall occur with payment of the Closing Purchase Price less the amount of such disputed item or items (but only to the extent of dispute); provided, however, that Title Defects and Environmental Defects shall be addressed as set forth in Section 2.4(b)(iv).

The representations and warranties of Seller and Buyer made in or pursuant to this Agreement will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby until the one-year anniversary of the Closing Date; provided that any claim for indemnification will survive until such claim is finally resolved if Buyer notifies Seller, or if Seller notifies Buyer, as applicable, of such claim in reasonable detail prior to the date which is the one-year anniversary of the Closing Date. Without limiting the foregoing, no claim for indemnification pursuant to Section 8.1(a) or Section 8.2(a) based on the breach or alleged breach of a representation or warranty may be asserted after the date on which such representation or warranty expires hereunder. The covenants and agreements of Seller and Buyer made in or pursuant to this Agreement will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby indefinitely.

8.4. Notice. Any party entitled to receive indemnification under this Article VIII (the “Indemnified Party”) agrees to give prompt written notice to the party required to provide such indemnification (the “Indemnifying Party”) promptly after becoming aware of the occurrence of any indemnifiable Loss or the assertion of any claim or the commencement of any action or proceeding in respect of which such a Loss may reasonably be expected to occur (a “Claim”), but the Indemnified Party’s failure to give such notice will not affect the obligations of the Indemnifying Party under this Article VIII except to the extent that the Indemnifying Party is

materially prejudiced thereby. Such written notice will include a reference to the event or events forming the basis of such Loss or Claim and the amount involved, unless such amount is uncertain or contingent, in which event the Indemnified Party will give a later written notice when the amount becomes fixed.

8.5. Defense of Claims.

(a) The Indemnifying Party may elect to assume and control the defense of any Claim, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of expenses related thereto, if: (i) the Indemnifying Party acknowledges its obligation to indemnify the Indemnified Party for any Losses resulting from such Claim; and (ii) the Claim does not seek to impose any Liability on the Indemnified Party other than money damages.

(b) If the conditions of Section 8.5(a) are satisfied and the Indemnifying Party elects to assume and control the defense of a Claim, then: (i) the Indemnifying Party will not be liable for any settlement of such Claim effected without its consent, which consent will not be unreasonably withheld; (ii) the Indemnifying Party may settle such Claim without the consent of the Indemnified Party only if (A) all monetary damages payable in respect of the Claim are paid by the Indemnifying Party, (B) the Indemnified Party receives a full, complete and unconditional release in respect of the Claim without any admission or finding of obligation, liability, fault or guilt (criminal or otherwise) with respect to the Claim, and (C) no injunctive, extraordinary, equitable or other relief of any kind is imposed on the Indemnified Party or any of its Affiliates; (iii) the Indemnifying Party may otherwise settle such Claim only with the consent of the Indemnified Party, which consent will not unreasonably be withheld or delayed; and (iv) the Indemnified Party may employ separate counsel and participate in the defense thereof, but the Indemnified Party will be responsible for the fees and expenses of such counsel unless: (1) the Indemnifying Party has failed to adequately assume and actively conduct the defense of such Claim or to employ counsel with respect thereto; or (2) in the reasonable opinion of the Indemnified Party, a conflict of interest exists between the interests of the Indemnified Party and the Indemnifying Party that requires representation by separate counsel, in which case the fees and expenses of such separate counsel will be paid by the Indemnifying Party.

(c) If the conditions of Section 8.5(a) are not satisfied, the Indemnified Party may assume the exclusive right to defend, compromise or settle such Claim, but the Indemnifying Party will not be bound by any determination of a Claim so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld); provided, that the Indemnified Party will not be required to obtain any consent of the Indemnifying Party to the determination of such Claim (and will not prejudice its right to be indemnified with respect to such Claim by settling such Claim) if the Indemnifying Party is asserting that it has no obligation to indemnify the Indemnified Party in respect of such claim.

8.6. Exclusive Monetary Remedy. The sole and exclusive monetary remedy for any Indemnified Party against any Indemnifying Party for any breach of any representation, warranty, agreement or covenant of such Indemnifying Party under this Agreement (including the covenants regarding Assumed Liabilities) shall be indemnification pursuant to this Article VIII, except in the case of fraud or willful misconduct by the Indemnifying Party. Without limiting the foregoing, the exercise by an Indemnified Party of its right to indemnification under Article VIII shall not affect the right of such Indemnified Party to seek an injunction or other equitable relief with respect to the matter giving rise to such exercise.

8.7. Limitation on Damages. No Indemnified Party will be entitled to indemnification pursuant to Section 8.1 or Section 8.2 for punitive damages, or for lost profits (except where such lost profits constitute direct damages, such as Losses resulting from a breach of Section 8.1), consequential, exemplary, special or similar damages, provided, however, that this provision shall not limit an Indemnified Party’s right to indemnification under Section 8.1 or Section 8.2 to recover Losses that arise as the result of a third-party claim against the Indemnified Party for, lost profits, consequential, special or similar actual damages.

8.8. Title Defects. Buyer’s sole and exclusive remedy with respect to Title Defects or Losses arising thereunder, shall be as provided in Exhibit A.

8.9. Disclaimer of Other Representations and Warranties.

(a) The express representations and warranties of Seller contained in this Agreement are exclusive and are in lieu of all other representations and warranties, express, implied, or statutory. EXCEPT FOR THE EXPRESS REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS OF SELLER SET FORTH IN THIS AGREEMENT AND THE ASSIGNMENT, SELLER HAS NOT MADE, AND SELLER HEREBY EXPRESSLY DISCLAIMS AND NEGATES, AND BUYER HEREBY EXPRESSLY WAIVES, ANY REPRESENTATION OR WARRANTY, EXPRESS, IMPLIED, AT COMMON LAW, BY STATUTE OR OTHERWISE RELATING TO (A) PRODUCTION RATES, RECOMPLETION OPPORTUNITIES, DECLINE RATES, GAS BALANCING INFORMATION OR THE QUALITY, QUANTITY, OR VOLUME OF THE RESERVES OF HYDROCARBONS, IF ANY, ATTRIBUTABLE TO THE ASSETS, (B) THE ACCURACY, COMPLETENESS OR MATERIALITY OF ANY INFORMATION, DATA OR OTHER MATERIALS (WRITTEN OR ORAL) NOW, HERETOFORE OR HEREAFTER FURNISHED TO BUYER BY OR ON BEHALF OF SELLER, (C) THE ENVIRONMENTAL CONDITION OF THE PROPERTIES, (D) ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, (E) ANY IMPLIED OR EXPRESS WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE, (F) ANY IMPLIED OR EXPRESS WARRANTY OF CONFORMITY TO MODELS OR SAMPLES OF MATERIALS, (G) ANY RIGHTS OF PURCHASERS UNDER APPROPRIATE STATUTES TO CLAIM DIMINUTION OF CONSIDERATION, AND (H) ANY AND ALL IMPLIED WARRANTIES EXISTING UNDER APPLICABLE LAW; IT BEING THE EXPRESS INTENTION OF BOTH BUYER AND SELLER THAT SUBJECT TO AND WITHOUT LIMITING SELLER’S EXPRESS REPRESENTATION AND WARRANTIES

SELLER AND BUYER AGREE THAT, TO THE EXTENT REQUIRED BY APPLICABLE LAW TO BE EFFECTIVE, THE DISCLAIMERS OF CERTAIN WARRANTIES CONTAINED IN THIS SECTION ARE “CONSPICUOUS” DISCLAIMERS FOR THE PURPOSES OF ANY APPLICABLE LAW, RULE OR ORDER.

(b) Buyer acknowledges that the Properties have been used for exploration, development, production, handling, transporting and/or processing of oil and gas and that there may be petroleum, produced water, wastes, or other materials located on or under the Properties or associated with the premises.

EXHIBIT A

PROCEDURE FOR CLAIMING TITLE AND ENVIRONMENTAL DEFECTS

AND ADJUSTING THE PURCHASE PRICE

1. Title and Environmental Procedure. From the date of this Agreement until 5:00 p.m. Central time on the 75^th day following the first Business Day following the date of this Agreement (the “Examination Period”), Seller will afford to Buyer and its representatives reasonable access during normal business hours to the offices, personnel and books and records of Seller in order for Buyer to conduct a title examination and environmental examination as it may in its sole discretion choose to conduct with respect to the Assets in order to determine whether Title Defects or Environmental Defects exist.

2. Accessible Information; Expenses; Confidential Information; Indemnification. Buyer and its representatives may examine all abstracts of title, title opinions, title files, ownership maps, lease files, assignments, division orders, operating records and agreements, well files, financial and accounting records, geological, geophysical, engineering and environmental records, in each case insofar as the same may now be in existence and in the possession of Seller, provided, however, that Seller may withhold access to (a) all legally privileged documents other than title opinions and (b) information that Seller is prohibited from disclosing by third party confidentiality restrictions; provided further that Seller will use its reasonable efforts to obtain a waiver of any such restrictions in favor of Buyer. The cost and expense of Buyer’s review of the title to the Assets and environmental conditions on the Assets will be borne solely by Buyer. Buyer will not contact any of the customers or suppliers of Seller or its Working Interest co-owners, operators, lessors or surface interest owners, in connection with the transactions contemplated hereby, whether in person or by telephone, e-mail, mail or other means of communication, without the specific prior written authorization of Seller, which consent will not be unreasonably withheld. Buyer will indemnify and hold harmless Seller and its officers, directors, agents, representatives, employees, successors, and assigns against any damages arising from or in connection with Buyer’s due diligence examination of title to the Assets or the environmental conditions of the Assets; provided, however, that damages, for this purpose only, shall not include damages to the extent resulting solely from the discovery by Buyer or its representatives of any pre-existing condition.

3. Notice of Asserted Title Defects or Environmental Defects. If Buyer discovers any Title Defect or Environmental Defect affecting any of the Assets, Buyer may, as a predicate to receiving a Purchase Price adjustment, notify Seller of such alleged Title Defect or Environmental Defect prior to the expiration of the Examination Period, provided, that such allegation is made in good faith. To be effective, such notice (“Title Defect Notice” or “Environmental Defect Notice”, respectively) must

(a)

be in writing,

(b)

be received by Seller prior to the expiration of the Examination Period,

(c)

describe the Title Defect or Environmental Defect in reasonable detail including the basis therefore (including any alleged variance in the Net Revenue Interest or Working Interest of any alleged Title Defect) and any supporting documents,

A - 1

(d)

identify the specific Assets to which such Title Defect or Environmental Defect relates, and

(e)

include the value of such Title Defect or Environmental Defect as determined by Buyer in good faith.

Notwithstanding anything to the contrary herein, at the end of the Examination Period, any matters that may otherwise constitute a Title Defect or Environmental Defect, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, will be deemed to have been waived by Buyer for all purposes; provided that, with respect to defects other than Title Defects, such waiver shall not limit or affect the existence or survival of representations and warranties.

4. Cure. Upon the receipt of an effective Title Defect Notice or Environmental Defect Notice from Buyer, Seller will have the option, but not the obligation, to attempt to cure such Title Defect or Environmental Defect during the Cure Period (as hereinafter defined) at Seller’s sole cost and expense. A Property affected by such Title Defect or Environmental Defect will be referred to as a “Title Defect Property” or “Environmental Defect Property”, respectively.

5. Defensible Title. As used in this Exhibit A, “Defensible Title” means, as of the date of this Agreement and the Closing Date, with respect to the Leases described on Schedule 3.4(b), such record title and ownership by Seller that:

(a)

entitles Seller to receive and retain from such Lease, without reduction, suspension or termination, not less than the percentage set forth on Schedule 3.4(b) as the Net Revenue Interest of all hydrocarbons produced, saved and marketed from such Lease;

(b)

obligates Seller to bear a percentage of the costs and expenses relating to the maintenance, development and operation of such Lease that is not more than the Working Interest set forth for such Lease on Schedule 3.4(b), (unless such increase is accompanied by a proportionate increase in the Net Revenue Interest applicable to such Lease);

(c)

is free and clear of all encumbrances except Permitted Encumbrances; and

(d)

would generally be accepted in the industry without objection.

6. Title Defect Amount; Environmental Defect Amount. “Title Defect Amount” or “Environmental Defect Amount” means, with respect to a Title Defect Property or Environmental Defect Property, as applicable, the reduction, in the Allocated Value (as set forth on Exhibit E, of an Asset as a result of the existence of one or more Title Defects or Environmental Defects, respectively, which amount will be determined as follows:

(a)

The Title Defect Amount with respect to a Title Defect Property will be determined by taking into consideration the Allocated Value of the Title Defect Property affected by such Title Defect (or if the Title Defect Property does not have a

A - 2

specific Allocated Value, then the Allocated Value thereof will be derived from the Allocated Value of the Lease or Well associated therewith), the portion of the Title Defect Property subject to such Title Defect, and the legal effect of such Title Defect on the Title Defect Property affected thereby; provided, however, that:

(i)

if such Title Defect is in the nature of the Net Revenue Interest in a Lease being less than the Net Revenue Interest set forth on Schedule 3.4(b) with respect thereto and the corresponding Working Interest remains the same, then the Title Defect Amount will be the Allocated Value for the relevant Lease multiplied by the percentage reduction in such Net Revenue Interest as a result of such Title Defect;

(ii)

if such Title Defect is in the nature of an Encumbrance, then the Title Defect Amount will be the amount required to fully discharge such Encumbrance; and

(iii)

if the Title Defect results from any matter not described in sub-paragraph (i) or sub-paragraph (ii) above, the Title Defect Amount will be an amount equal to the difference between the value of the Title Defect Property with such Title Defect and the value of such Title Defect Property without such Title Defect (taking into account the Allocated Value of the Title Defect Property). A Title Defect Amount may not exceed the Allocated Value of the Title Defect Property.

(b)

Notwithstanding the foregoing, any matters that would otherwise constitute a Title Defect will not be a Title Defect if it is not reasonably likely to affect the market value to Buyer of the affected Asset based on the standards and practices of reasonably prudent operators of oil and gas xxxxx in the Permian Basin.

(c)

The Environmental Defect Amount with respect to an Environmental Defect Property will be determined by taking into consideration the Allocated Value of the Environmental Defect Property affected by such Environmental Defect (or if the Environmental Defect Property does not have a specific Allocated Value, then the Allocated Value thereof will be derived from the Allocated Value of the Lease or Well associated therewith), the portion of the Environmental Defect Property subject to such Environmental Defect, and the decrease in value of such Environmental Defect Property resulting from such Environmental Defect, the amount of the civil penalty or fine assessed (or likely to be assessed) for such violation where the Environmental Defect is a violation of Environmental Law, or the cost to cure or otherwise remediate the Environmental Defect on such Environmental Defect Property, as applicable; provided the Environmental Defect Amount, for purposes of calculating a Purchase Price adjustment, may not exceed the Allocated Value of the Environmental Defect Property.

A - 3

7. Procedures for Title Defects and Environmental Defects.

(a)

If Seller and Buyer agree that a Title Defect or Environmental Defect exists and if prior to the Closing Date, Seller has been unable to cure such Title Defect or Environmental Defect (and there is no dispute as to whether or not it has been cured), and Buyer and Seller agree that Seller will not be able to cure such Title Defect or Environmental Defect within 60 days after the expiration of the Examination Period (the “Cure Period”), then the Purchase Price will be reduced by the Title Defect Amount or Environmental Defect Amount, with respect to such Title Defect Property or Environmental Defect Property (taking into account the results of any curative efforts made by or on behalf of Seller with respect to such Title Defect Property or Environmental Defect Property).

(b)

If Seller and Buyer are unable to reach an agreement at any time as to whether a Title Defect or Environmental Defect exists or, if it does exist, whether it has been cured or the amount of the Title Defect Amount or Environmental Defect Amount attributable to such Title Defect or Environmental Defect, then dispute resolution procedures may be initiated by Seller or Buyer under Section 8 of this Exhibit A promptly following the inability to reach an agreement.

(c)

Buyer will act in good faith and reasonably cooperate with Seller after the Closing to cure any Title Defects or Environmental Defects that have not been cured or resolved pursuant to Section 7(a) of this Exhibit A. If, at the end of the Cure Period, Seller has been unable to cure a Title Defect or Environmental Defect (and there is no dispute as to whether or not it has been cured), Seller will pay Buyer, within 30 days, the Title Defect Amount or Environmental Defect Amount with respect to such Title Defect or Environmental Defect (taking into account the value of the results of any curative efforts made by or on behalf of Seller with respect to such Title Defect or Environmental Defect).

(d)

Notwithstanding anything to the contrary contained herein, Seller will have the option, but not the obligation, within 60 days after the resolution of any dispute as to any Title Defect Property or Environmental Defect Property as to which the Title Defect Amount or Environmental Defect Amount exceeds fifty percent (50%) of the Allocated Value, to retain any Title Defect Property or Environmental Defect Property or to cause to be assigned any Title Defect Property or Environmental Defect Property to Buyer and the Purchase Price will be adjusted as set forth in Section 7(a) of this Exhibit A. If Seller exercises its option to retain any Title Defect Property or Environmental Defect Property, then Buyer will transfer such Title Defect Property or Environmental Defect Property to Seller, and Seller will pay Buyer an amount equal to the Allocated Value of such Title Defect Property or Environmental Defect Property.

(e)

Notwithstanding any election by Seller to cause any Title Defect Property or Environmental Defect Property meeting the fifty percent (50%) threshold to be assigned to Buyer pursuant to subsection (d) immediately above, Buyer will have the option, but not the obligation, within 10 days after receipt of notice of a Seller election pursuant to subsection (d)

A - 4

immediately above, to elect to remove any Title Defect Property or Environmental Defect Property meeting the fifty percent (50%) from this Agreement and, if applicable, convey such Title Defect Property or Environmental Defect Property to Seller, if same had previously been conveyed to Buyer, with the Purchase Price being adjusted as set forth in Section 7(a) of this Exhibit A.

8. Arbitration.

(a)

In the event of any dispute with respect to this Exhibit A, the parties hereto agree to make reasonable efforts to come to a mutually acceptable resolution of such dispute among themselves prior to the involvement of any third-party intermediary. If any party hereto elects to submit any dispute to arbitration as specifically provided in this Section 8, then such party will notify the other party in writing. Within 15 days following such notice, Seller and Buyer agree to jointly select an arbitrator. For disputes regarding Title Defects or Title Defect Amounts, the arbitrator will be an experienced oil and gas attorney, familiar by training and experience with U.S. oil and gas legal and business matters including titles and oil and gas transactions. This person will be the sole arbitrator (the “Title Defect Arbitrator”) to hear and decide all existing disputes regarding asserted Title Defects and Title Defect Amounts. For disputes regarding Environmental Defects or Environmental Defect Amounts, the arbitrator will be an experienced environmental attorney, familiar by training and experience with U.S. environmental legal and business matters in the oil and gas industry. This person will be the sole arbitrator (the “Environmental Defect Arbitrator”) to hear and decide all existing disputes regarding asserted Environmental Defects and Environmental Defect Amounts. If Seller and Buyer are unable to agree on the Title Defect Arbitrator or Environmental Defect Arbitrator within the 15 day period, any Party hereto may apply to a court in the State of Texas, regarding asserted Title Defects and Title Defect Amounts or Environmental Defects and Environmental Defect Amounts for the selection of a Title Defect Arbitrator or Environmental Defect Arbitrator, respectively, with the qualifications set forth in this paragraph.

(b)

Any arbitration hearing, if one is desired by the Title Defect Arbitrator or Environmental Defect Arbitrator, will be held in Xxxxxx County, Texas, or such other location acceptable to both parties and the Title Defect Arbitrator or Environmental Defect Arbitrator. The Parties may mutually elect to conduct the proceeding by written submissions from Seller and Buyer with exhibits, including interrogatories, supplemented with appearances by Buyer and Seller as the Title Defect Arbitrator or Environmental Defect Arbitrator may desire. The arbitration proceeding, subject only to the terms hereof, will be conducted informally and expeditiously (the intention of the parties being that the Arbitration shall allow only that minimum discovery determined by the Arbitrator to be reasonably necessary to protect the integrity of the process) and in such a manner as to result in a good faith resolution as soon as reasonably possible under the circumstances. The decision of the Title Defect Arbitrator or Environmental Defect Arbitrator with respect to such remaining disputed matters will be

A - 5

reduced to writing and binding on the parties. Judgment upon the award(s) rendered by the Title Defect Arbitrator or Environmental Defect Arbitrator may be entered and execution had in any court of competent jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement. Seller and Buyer will bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the Title Defect Arbitrator or Environmental Defect Arbitrator will be shared equally by the parties.

The arbitration will commence as soon as possible after the Title Defect Arbitrator or Environmental Defect Arbitrator is selected in accordance with the provisions of this Section 8 of this Exhibit A.

(f)

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