an amount equal to any and all ad valorem, property, production, excise, severance and similar taxes (other than income taxes) and assessments based upon or measured by the ownership of the Purchased Assets paid by or on behalf of Seller that is attributable to periods of time from and after the Effective Time, which

4

Access to Purchased Assets and Records.  (a) Subject to the terms and conditions of the Confidentiality Agreement dated February 19, 2008 (the “Confidentiality Agreement”), by and between Buyer and Seller, from the date of this Agreement until the Closing, Seller shall cooperate with Buyer and provide Buyer and its representatives, consultants, and current and prospective lenders and advisors, and each of their authorized representatives reasonable access to the Purchased Assets and reasonable access to the Records, but only to the extent that Seller may do so without violating any obligations to any third party and to the extent that Seller has authority to grant such access without breaching any restriction legally binding on Seller. Buyer shall conduct all such inspections and other information gathering described above only (i) (x) during regular business hours and (y) during any weekends and after hours requested by Buyer that can be reasonably accommodated by Seller, and (ii) in a manner which will not unduly interfere with Seller’s operation of the Purchased Assets.

(b)

Subject to the Confidentiality Agreement from the date of this Agreement until the Closing, Seller shall afford to Buyer and its officers, employees, agents and current and prospective lenders and each of their authorized representatives reasonable access to the Purchased Assets, including the Records in accordance with Section 5.7(a). During such period, Seller shall also make available to Buyer, upon reasonable notice during normal business hours, Seller’s personnel knowledgeable with respect to the Purchased Assets in order that Buyer may make such diligent investigation as Buyer considers desirable. For those Purchased Assets that are not operated by Seller, Seller shall use commercially reasonable efforts to obtain permission from the operator for Buyer to conduct such inspections but, provided Seller has exercised such commercially reasonable efforts, Seller shall have no liability to Buyer for failure to obtain any such operator’s permission. Upon reasonable notice to Seller, Buyer shall have the right to conduct an environmental assessment of all or any portion of the Purchased Assets (the “Assessment”), to be conducted by Buyer’s personnel or a reputable environmental consulting or engineering firm approved in advance in writing by Seller (such approval not to be unreasonably withheld), but only to the extent that Seller may grant such right without violating any obligations to any third party (provided that Seller shall use its Reasonable Best Efforts to obtain any necessary third party consents to any Assessment to be conducted by Buyer).  The Assessment shall be conducted at the sole cost and expense of Buyer. After completing any Assessment of the Purchased Assets, Buyer shall, at its sole cost and expense, restore the Purchased Assets to their condition prior to the commencement of such Assessment, unless Seller requests otherwise, and shall promptly dispose of all drill cuttings, corings, or other investigative-derived wastes generated in the course of the Assessment. Upon Seller’s written request, Buyer shall provide Seller with a copy of the final version of all environmental reports prepared by, or on behalf of, Buyer with respect to any Assessment conducted on the Purchased Assets. In the event that any necessary disclosures under applicable laws are required with respect to matters discovered by any Assessment conducted by, for or on behalf of Buyer, Buyer agrees that Seller shall be the responsible party for disclosing such matters to the appropriate Governmental Entities; provided that, if Seller fails to promptly make such disclosure and Buyer or any of its Affiliates is legally obligated to make such disclosure, Buyer or any of its Affiliates, as applicable, shall have the right to fully comply with such legal obligation. If, by the Objection Date, as a result of its investigation pursuant to this Section 5.7(b), Buyer determines that with respect to the Purchased Assets, there exists a violation of any Environmental Law (an “Environmental Defect”), the Parties agree to negotiate in good faith a resolution satisfactory to both Parties.  If such a resolution is not reached prior to Closing with respect to any

18

such Environmental Defect, the affected Purchased Asset(s) shall be held back from the Purchased Assets to be transferred and conveyed to Buyer at Closing and the Purchase Price to be paid at Closing shall be reduced by the Allocated Value of the Purchased Asset(s) held back, and the parties shall have the rights and remedies set forth in Section 5.7(c) below with respect thereto.

(c)

With respect to any Purchased Asset(s) held back from the initial Closing pursuant to Section 5.7(b) above, the Parties shall have the following rights and remedies:

(i)

Seller shall have the right, but not the obligation, to cure the Environmental Defect to the reasonable satisfaction of Buyer, so long as such cure is accomplished on or before 180 days following the initial Closing (the “Environmental Cure Period”).  Within ten (10) days following the date that Seller provides Buyer with reasonably satisfactory evidence that an Environmental Defect has been cured, Seller shall sell, assign and convey to Buyer, and Buyer shall purchase and accept from Seller, the affected Purchased Asset, in accordance with and subject to the terms and conditions of this Agreement, and Buyer shall pay to Seller the amount by which the Purchase Price was reduced at the initial Closing with respect to such affected Purchased Asset.  Contemporaneously with the assignment of the affected Purchased Asset to Buyer, Seller shall be released from all further liability or obligation to Buyer with respect to such affected Purchased Asset.  

(ii)

Seller may notify Buyer in writing that it has elected to indemnify Buyer from all liabilities and obligations arising out of the Environmental Defect, but only if Buyer agrees the indemnity, in such circumstance, is an appropriate remedy, and if the Parties can mutually agree on the form of the indemnity.  Within ten (10) days following the date that Seller notifies Buyer that Seller has elected to indemnify Buyer under this 5.7(c)(ii), Seller shall sell, assign and convey to Buyer, and Buyer shall purchase and accept from Seller, the affected Purchased Asset, in accordance with and subject to the terms and conditions of this Agreement, and Buyer shall pay to Seller the amount by which the Purchase Price was reduced at the initial Closing with respect to such affected Purchased Asset.  If Seller later cures the Environmental Defect to Buyer’s reasonable satisfaction, the indemnity and all further liability or obligation to Buyer with respect to the affected Purchase Asset shall terminate.

(iii)

If an Environmental Defect has not been resolved under Section 5.7(c)(i) or (ii) above by the end of the Environmental Cure Period, either Party may refer the matter to arbitration (pursuant to the procedures set forth in Section 8.3(d)) for determination of the existence of and/or the value of such Environmental Defect at the time of the arbitration (the “Environmental Defect Value”).  The determination of the arbitrator shall be binding on the Parties.  Within ten (10) days following the date of the arbitrator’s decision, Seller shall sell, assign and convey to Buyer, and Buyer shall purchase and accept from Seller, the affected Purchased Asset, in accordance with and subject to the terms and conditions of this Agreement, and Buyer shall pay to Seller the amount by which the Purchase Price was reduced at the initial Closing with respect to such affected Purchased Asset less any Environmental Defect Value.  Contemporaneously with the assignment of the affected Purchased Asset to Buyer, Seller shall be released from all further liability or obligation to Buyer with respect to the affected Purchased Asset.

19

(d)

Seller and Buyer shall preserve until the fifth (5th) anniversary of the Closing Date all records possessed or to be possessed by such Party relating to any of the Purchased Assets prior to the Closing Date. After the Closing Date, where there is a legitimate purpose, such Party shall provide the other Party with access, upon prior reasonable written request specifying the need therefor, during regular business hours, to (a) the officers and employees of such Party and (b) the books of account and records of such Party, but, in each case, only to the extent relating to the Purchased Assets prior to the Closing Date, and the other Party and its representatives shall have the right to make copies of such books and records; provided, however, that the foregoing right of access shall not be exercisable in such a manner as to interfere unreasonably with the normal operations and business of such Party. Such records may nevertheless be destroyed by a Party if such Party sends to the other Party written notice of its intent to destroy records, specifying with particularity the contents of the records to be destroyed. Such records may then be destroyed after the thirtieth (30th) day after such notice is given unless another Party objects to the destruction in which case the Party seeking to destroy the records shall deliver such records to the objecting Party.

5.8

Further Assurances.  Upon the terms and subject to the conditions hereof, the Parties hereto shall execute such documents and other instruments and take such further actions as may be reasonably required to carry out the provisions hereof and consummate the transactions contemplated by this Agreement.

5.9

Delivery of Books and Records to Buyer.  Seller shall, within thirty (30) days after Closing, deliver the Records to Buyer.

5.10

Letters in Lieu; Assignments; Operatorship.  (a) Seller will execute on the Closing Date letters in lieu of division and transfer orders relating to the Purchased Assets, on forms prepared by Seller and reasonably satisfactory to Buyer, to reflect the transaction contemplated hereby.

(b)

Seller will prepare and execute, and Buyer will execute, on the Closing Date, all assignments necessary to convey to Buyer all federal and state Leases, if any, in the form as prescribed by the applicable Governmental Entity and otherwise acceptable to Buyer and Seller.

(c)

Seller makes no representations or warranties to Buyer as to transferability or assignability of operatorship of any Purchased Assets.  Seller is not aware of any effort by any third party to have Seller removed as operator of any property for which it is currently operator.  Rights and obligations associated with operatorship of such Purchased Assets are governed by operating and similar agreements covering the Purchased Assets and will be determined in accordance with the terms of such agreements.  However, Seller will assist Buyer in Buyer’s efforts to succeed Seller as operator of any Wells and units included in the Purchased Assets where Seller currently serves as operator.  Buyer shall, promptly following Closing, file all appropriate forms and declarations or bonds with federal and state agencies relative to its assumption of operatorship.  For all operated Purchased Assets, Seller shall execute and deliver to Buyer on the Closing Date, and Buyer shall promptly file the appropriate forms with the applicable regulatory agency transferring operatorship of such Assets to Buyer.

6.3

Defensible Title; Development Acreage.  For purposes of the Title Defect Notice set forth in Section 6.8 only, Seller’s title to any non-producing acreage (“Development Acreage”) included in the Leases shall be presumed to be Defensible Title unless Buyer can show through actual evidence submitted with a Title Defect Notice that Seller’s title to such Development Acreage (or any portion thereof) has failed or that the Development Acreage is subject to a lien or encumbrance (except for Permitted Encumbrances) that would constitute a material loss of interest in such Development Acreage, or the Net Mineral Acres making up such Development Acreage is less than the Net Mineral Acres set forth in Exhibit A.  Development Acreage does not include eWell Locations that have been given a specific Allocated Value on Exhibit D.

(a)

defects based on lack of information in Seller’s files;

defects asserting a change in Net Revenue Interests or Working Interests based on an after-payout decrease in Net Revenue Interests or increase in Working Interests pursuant to a farm-in, farm-out or other agreement that is listed on Schedule 6.6, if the effect of such change is reflected in the Net Revenue Interests and Working Interests set forth in Exhibit A, C or D, as applicable;

(f)

defects related to suspension of revenues due and owing to Seller, if such suspension is not supported by facts and circumstances that would otherwise be a Title Defect; and

(g)

defects that have been cured or that are not material in light of the entire chain of title or subsequent agreements.

6.7

Title Defect Value.  “Title Defect Value” means the value of the Title Defect determined in accordance with the following:

(a)

If the Title Defect is a reduction in the Net Revenue Interests in respect of the Lease, the Title Defect Value thereof shall be equal to the Allocated Value of the Lease multiplied by a fraction the numerator of which is the positive difference between the actual Net Revenue Interest of Seller in the Lease and the Net Revenue Interest set forth for such Lease on Exhibit A and the denominator of which is the Net Revenue Interest set forth for such Lease on Exhibit A;

(b)

If the Title Defect is a lien or encumbrance other than a Permitted Encumbrance, the cost of removing the lien or encumbrance;

(c)

If the Title Defect is the increase in the Working Interests in respect of the Lease to the extent such increase is not accompanied by a corresponding increase in the Net

23

Revenue Interests, the Title Defect Value thereof shall be determined by Buyer in good faith in its reasonable discretion; and

(d)

If the Title Defect represents only a possibility of title failure, the probability that such failure will occur will be taken into account in determining the Title Defect Value thereof.  In every instance the legal and practical effect of the Title Defect shall be taken into account in the determination of the Title Defect Value thereof.

Only that portion of the Lease that is materially and adversely affected by a Title Defect shall be considered for purposes of determining the Title Defect Value.

6.8

Title Defect Notice.  Buyer shall give Seller notice of any Title Defects (“Title Defect Notice”) as soon as possible but no later than April 28, 2008 (such date being referred to herein as the “Objection Date”).  The Title Defect Notice must include all of the following:

(a)

a description of the Title Defect;

(b)

a description of the reasonable basis for the Title Defect;

(c)

Reasonable Documentation supporting the basis for the Title Defect;

(d)

evidence supporting Buyer’s belief that the Title Defect has not been released or cured and is still enforceable; and

(e)

the identity and the Allocated Value of the Lease.

6.9

Assumed Title Liabilities.  Any notice that is not timely and properly given or that does not satisfy all of the foregoing shall not be a valid Title Defect Notice, and any Title Defects not included in a valid Title Defect Notice shall be deemed to be “Assumed Title Liabilities” and to have been waived or assumed by Buyer. Notwithstanding anything to the contrary contained in this Agreement, except as to any Title Defects subject to Section 6.11(b) or Section 6.13(b), after Closing, Seller’s only warranty of title to the Purchased Assets shall be that, as to claims arising by, through or under Seller, Seller has Defensible Title to the Oil and Gas Interests.

6.10

Reasonable Documentation.  “Reasonable Documentation” means a copy of any available title opinion or other explanations describing the Title Defect and

(a)

a copy of the relevant document, if the basis is a document;

(b)

the deed preceding and following a gap in the chain of title or a title opinion describing the gap in reasonable detail, if the basis is a gap in Seller’s chain of title;

(c)

a copy of the document creating the lien or encumbrance, if the basis is a lien or encumbrance, together with evidence supporting Buyer’s determination that the lien or encumbrance has not been released and is still enforceable; or

24

(d)

any other reasonable documentation or explanation supporting the Title Defect.

6.11

Seller’s Options.  Seller shall have the right to cure any Title Defect but shall have no obligation to do so. If Buyer gives a Title Defect Notice, Seller shall have the option of:

(a)

curing the Title Defect before Closing, and, if such Title Defect is not cured before Closing, Seller shall further elect (b), (c) or (d);

(b)

indemnifying Buyer for all liabilities and obligations associated with the Title Defect, which indemnity shall terminate if Seller later cures the Title Defect, but only if Buyer agrees the indemnity, in such circumstance, is an appropriate remedy, and if the Parties can mutually agree on the form of the indemnity;

(c)

reducing the Purchase Price by the Title Defect Value, subject to the Title Defect Threshold and Title Defect Deductible described in Section 6.12, in which event Seller shall be released from and of all further liability or obligation to Buyer with respect to the Title Defect, and the Title Defect shall be a Permitted Encumbrance; or

(d)

if the Title Defect Value exceeds twenty percent (20%) of the Allocated Value of the Well or Well Location, excluding the Well or Well Location from the Purchased Assets conveyed to Buyer at the Closing, subject to Section 6.13, in which event the Purchase Price shall be reduced by the Allocated Value of the Well or Well Location, as applicable.

6.12

Adjustment to Purchase Price; Threshold and Deductible.  At Closing, the Purchase Price may be adjusted for Title Defect Values as set forth in Section 6.11(c); provided, however, notwithstanding anything to the contrary herein, there shall be no cure, remedy, deletion or adjustment to the Purchase Price whatsoever in respect of any Title Defects unless the aggregate value of all Title Defects equals or exceeds one percent (1%) of the Purchase Price (the “Title Defect Threshold Amount”). Once the Title Defect Threshold Amount has been reached, the amount of reduction in Purchase Price shall be the amount of Title Defect Values that exceed one-half of one percent (0.5%) of the Purchase Price (the “Title Defect Deductible”).  For avoidance of doubt, there shall be no adjustment to the Purchase Price for Title Defects cured or remedied in accordance with Section 6.11(a) or 6.11(b) and the Title Defect Threshold Amount and the Title Defect Deductible Amount shall not apply to any Title Defect arising by, through or under Seller.

6.13

Exclusions of Wells.  Pursuant to Section 6.11(d), if the Title Defect Value exceeds twenty percent (20%) of the Allocated Value of a Well or Well Location, Seller shall have the option to exclude such Well or Well Location from the Purchased Assets conveyed to Buyer at the Closing by notifying Buyer on or before the Closing, in which event the Purchase Price shall be reduced by the Allocated Value of such Well or Well Location. If the Title Defect Value exceeds twenty percent (20%) of the Allocated Value of the Well or Well Location and the Well or Well Location is excluded from the Purchased Assets conveyed to Buyer at the Closing, Seller may elect any one or more of the following:

25

(a)

if Seller cures the Title Defect to Buyer’s reasonable satisfaction before the date that is one hundred eighty (180) days after the Effective Time, Seller may convey the Well or Well Location affected by the Title Defect to Buyer on the date that is one hundred eighty (180) days after the Effective Time, subject to all of the terms and conditions of this Agreement, and Buyer shall pay to Seller the amount by which the Purchase Price was reduced with respect to the Well Location; or

(b)

if Seller does not cure the Title Defect to Buyer’s reasonable satisfaction before the date that is one hundred eighty (180) days after the Effective Time but agrees to indemnify Buyer from all liabilities and obligations arising out of the Title Defect (which indemnity shall terminate if Seller later cures the Title Defect), Seller may convey the Well or Well Location affected by the Title Defect to Buyer on the date that is one hundred eighty (180) days after the Effective Time, subject to all of the terms and conditions of this Agreement, in which event Buyer shall pay to Seller the amount by which the Purchase Price was reduced with respect to the Well or Well Location, and Seller shall be released from all further liability or obligation to Buyer with respect to the Title Defect, and, subject to the indemnity provided above in this paragraph, the Title Defect shall be a Permitted Encumbrance.

6.14

Preference Rights and Transfer Requirements.  (a) The transactions contemplated by this Agreement are expressly subject to all validly existing and applicable Preference Rights and Transfer Requirements.  Prior to the Closing Date, Seller shall initiate all procedures which are reasonably required to comply with or obtain the waiver of all Preference Rights and Transfer Requirements with respect to the transactions contemplated by this Agreement. Seller shall use its Reasonable Best Efforts to obtain all applicable consents and to obtain waivers of applicable Preference Rights; provided, however, Seller shall not be obligated to pay any consideration to (or incur any cost or expense for the benefit of) the holder of any Preference Right or Transfer Requirement in order to obtain the waiver thereof or compliance therewith.

(b)

If the holder of a Preference Right elects prior to Closing to purchase the Purchased Asset subject to a Preference Right (a “Preference Property”) in accordance with the terms of such Preference Right, and Seller receives written notice of such election prior to the Closing, such Preference Property will be eliminated from the Purchased Assets and the Purchase Price shall be reduced by the Allocated Value of the Preference Property.

(c)

If

(i)

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

(ii)

a Purchased Asset is subject to a Transfer Requirement that provides that transfer of such Purchased Asset without compliance with such Transfer Requirement will result in termination or other material impairment of any rights in relation to such Purchased Asset, and such Transfer Requirement is not waived, complied with or otherwise satisfied prior to the Closing Date; or

26

(iii)

the holder of a Preference Right does not elect to purchase such Preference Property or waive such Preference Right with respect to the transactions contemplated by this Agreement prior to the Closing Date and the time in which the Preference Right may be exercised has not expired;

then, unless otherwise agreed by Seller and Buyer, the Purchased Asset or portion thereof affected by such Preference Right or Transfer Requirement (a “Retained Asset”) shall be held back from the Purchased Assets to be transferred and conveyed to Buyer at Closing and the Purchase Price to be paid at Closing shall be reduced by the Allocated Value of such Retained Asset without application of the Title Defect Threshold Amount or the Title Defect Deductible Amount. Any Retained Asset so held back at the initial Closing will be conveyed to Buyer at a delayed Closing (which shall become the new Closing Date with respect to such Retained Asset), within ten (10) days following the date on which the suit, action or other proceeding, if any, referenced in clause (i) above is settled or a judgment is rendered (and no longer subject to appeal) permitting transfer of the Retained Asset to Buyer pursuant to this Agreement and Seller obtains, complies with, obtains a waiver of or notice of election not to exercise or otherwise satisfies all remaining Preference Rights and Transfer Requirements with respect to such Retained Asset as contemplated by this Section (or if multiple Purchased Assets are Retained Assets, on a date mutually agreed to by the Parties in order to consolidate, to the extent reasonably possible, the number of Closings). At the delayed Closing, Buyer shall pay Seller a purchase price equal to the amount by which the Purchase Price was reduced on account of the holding back of such Retained Asset (as adjusted pursuant to Section 1.7 through the new Closing Date therefor); provided, however, if all such Preference Rights and Transfer Requirements with respect to any Retained Asset so held back at the initial Closing are not obtained, complied with, waived or otherwise satisfied as contemplated by this Section within one hundred eighty (180) days after the initial Closing has occurred with respect to any Purchased Asset, then such Retained Asset shall be eliminated from the Purchased Assets and shall become an Excluded Asset, unless Seller and Buyer agree to proceed with a closing on such Retained Asset, in which case Buyer shall be deemed to have waived any objection (and shall be obligated to indemnify the Seller Indemnitees for all Losses) with respect to non-compliance with such Preference Rights and Transfer Requirements with respect to such Retained Asset(s).

Indemnification Claims.  

(a)

(i)

If any third party notifies any Indemnified Party with respect to any matter (a “Third Party Claim “) that may give rise to a claim for indemnification against an Indemnifying Party under Article VIII, then the Indemnified Party shall promptly give written notification to the Indemnifying Party thereof. Such notification shall be given within ten (10) days after receipt by the Indemnified Party of notice of such Third Party Claim, and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Claim and the amount of the claimed damages (if available); provided, however, that no delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such failure.

30

(ii)

The Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party notifies the Indemnified Party in writing within thirty (30) days after the Indemnified Party has given notice of the Third Party Claim that the Indemnifying Party will indemnify the Indemnified Party from and against the Damages the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim (subject to the provisions of this Article VIII); (ii) the ad damnum, if any, is less than or equal to the amount of Damages for which the Indemnifying Party is liable under this Article VIII; (iii) the Indemnifying Party provides the Indemnified Party with evidence acceptable to the Indemnified Party that the Indemnifying Party will have the financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder; (iv) the Third Party Claim does not involve criminal liability and seeks only money damages and not equitable relief against the Indemnified Party; (v) settlement of, or an adverse judgment with respect to, the Third Party Claim is not, in the good faith judgment of the Indemnified Party, likely to establish a precedential custom or practice adverse to the continuing business interests or the reputation of the Indemnified Party, and (vi) the Indemnifying Party conducts the defense of the Third Party Claim actively and diligently.

(iii)

If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Claim, the Indemnified Party shall control such defense.

(iv)

The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Claim and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Claim (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Claim.

The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Claim without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld or delayed; provided that the consent of the Indemnified Party shall not be required if the Indemnifying Party agrees in writing to pay any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Indemnified Party from further

31

liability and has no other adverse effect on the Indemnified Party. The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld or delayed.

(b)

Within twenty (20) days after delivery of the notification of a Third Party Claim as provided in Section 8.3(a)(i) (a “Claim Notice”), the Indemnifying Party shall deliver to the Indemnified Party a response, in which the Indemnifying Party shall: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount to the extent the Claimed Amount may be finally determined at that time, by check or by wire transfer (provided that to the extent the Claimed Amount may not be finally determined at that time, the Indemnifying Party shall pay the Indemnified Party such additional amounts as to constitute the full Claimed Amount at such time as the full Claimed Amount can be finally determined)), (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer), or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount.

(c)

During the thirty (30) day period following the delivery of a Response that reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such thirty (30)-day period, the Indemnifying Party and the Indemnified Party shall discuss in good faith the submission of the Dispute to binding arbitration, and if the Indemnifying Party and the Indemnified Party agree in writing to submit the Dispute to such arbitration, then the provisions of Section 8.3(d) shall become effective with respect to such Dispute. The provisions of this Section 8.3(c) shall not obligate the Indemnifying Party and the Indemnified Party to submit to arbitration or any other alternative dispute resolution procedure with respect to any Dispute, and in the absence of an agreement by the Indemnifying Party and the Indemnified Party to arbitrate a Dispute, such Dispute shall be resolved in a state or federal court sitting in Houston, Texas, in accordance with Section 11.11.

(d)

If, as set forth in Section 8.3(c), the Indemnified Party and the Indemnifying Party agree to submit any Dispute to binding arbitration, the arbitration shall be conducted by a single arbitrator (the “Arbitrator”) in accordance with the Commercial Rules in effect from time to time and the following provisions:

(i)

In the event of any conflict between the Commercial Rules in effect from time to time and the provisions of this Agreement, the provisions of this Agreement shall prevail and be controlling.

(ii)

The parties shall commence the arbitration by jointly filing a written submission with the Houston, Texas office of the AAA in accordance with Commercial Rule 5 (or any successor provision).

(iii)

No depositions or other discovery shall be conducted in connection with the arbitration.

32

(iv)

Not later than thirty (30) days after the conclusion of the arbitration hearing, the Arbitrator shall prepare and distribute to the parties a writing setting forth the arbitral award and the Arbitrator’s reasons therefor. Any award rendered by the Arbitrator shall be final, conclusive and binding upon the parties, and judgment thereon may be entered and enforced in any court of competent jurisdiction (subject to Section 11.11), provided that the Arbitrator shall have no power or authority to (x) award damages in excess of the portion of the Claimed Amount that is subject to such Dispute, (y) award multiple, consequential, punitive or exemplary damages, or (z) grant injunctive relief, specific performance or other equitable relief.

(v)

The Arbitrator shall have no power or authority, under the Commercial Rules or otherwise, to (x) modify or disregard any provision of this Agreement, including the provisions of this Section 8.3(d), or (y) address or resolve any issue not submitted by the parties.

(vi)

In connection with any arbitration proceeding pursuant to this Agreement, each party shall bear its own costs and expenses, except that the fees and costs of the AAA and the Arbitrator, the costs and expenses of obtaining the facility where the arbitration hearing is held, and such other costs and expenses as the Arbitrator may determine to be directly related to the conduct of the arbitration and appropriately borne jointly by the parties (which shall not include any party’s attorneys’ fees or costs, witness fees (if any), costs of investigation and similar expenses) shall be shared equally by the Indemnified Party and the Indemnifying Party.

(e)

Notwithstanding the other provisions of this Section 8.3, if a third party asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VIII, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VIII and (iii) such Indemnified Party shall be reimbursed, in accordance with the provisions of this Article VIII, for any such Damages for which it is entitled to indemnification pursuant to this Article VIII (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VIII).

8.4

Survival of Representations, Warranties and Covenants.  (a) The representations and warranties made by Seller in this Agreement or any certificate required to be delivered at Closing to Buyer, and the representations and warranties of Buyer in this Agreement or any certificate required to be delivered at Closing to Seller, and the covenants and agreements of Seller and Buyer which by their terms do not contemplate performance after the Closing, shall survive the Closing and remain in full force and effect for one (1) year following the Closing Date. The foregoing notwithstanding, the representations and warranties in Sections 3.1, 3.2 and 3.9 shall survive until

33

the expiration of the applicable limitations period and the indemnification set forth in Section 8.1(d) shall survive until the final, non-appealable judgment of a court of competent jurisdiction relating to the litigation set forth on Schedule 3.8.

(b)

The rights to indemnification set forth in this Article VIII shall not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after the Closing Date, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder or (ii) any waiver by an Indemnified Party of any closing condition relating to the accuracy of representations and warranties or the performance of or compliance with agreements and covenants.

8.5

Limitations.  (a) Seller shall not have any obligation to indemnify the Buyer Indemnitees from and against any Damages under Section 8.1(a), other than Damages resulting by reason of any fraud or intentional misrepresentation, until the Buyer Indemnitees have suffered Damages by reason of all such breaches in excess of one percent (1%) of the Purchase Price (after which point Seller will be obligated to indemnify the Buyer Indemnitees from and against all such Damages in excess of the first one percent (1%) of the Purchase Price) and such indemnification obligation shall not exceed five percent (5%) of the Purchase Price except in the case of fraud or intentional misrepresentation; provided, however, that the foregoing thresholds, deductibles and limitations shall not apply to any indemnification provided by Seller arising out of any Title Defects subject to Section 6.11(c) or Section 6.13(b) or the representations and warranties in Sections 3.1, 3.2 and 3.9.

(b)

Buyer shall not have any obligation to indemnify the Seller Indemnitees from and against Damages under Section 8.2(a), other than Damages resulting by reason of any fraud or intentional misrepresentation, until the Seller Indemnitees have suffered Damages by reason of all such breaches in excess of one percent (1%) of the Purchase Price (after which point Buyer will be obligated to indemnify the Seller Indemnitees from and against all such Damages in excess of the first one percent (1%) of the Purchase Price) and such indemnification obligation shall not exceed five percent (5%) of the Purchase Price except in the case of fraud or intentional misrepresentation.

(c)

The rights of the Indemnified Parties under this Article VIII shall be the exclusive remedy of the Indemnified Parties with respect to any and all matters arising out of, relating to, or connected with this Agreement, Seller and its assets and liabilities, including, without limitation, the Purchased Assets and the Assumed Liabilities; provided, however, that notwithstanding any other provision of this Agreement, nothing herein shall limit any claim of any Party for remedies at law or in equity for fraud or intentional misrepresentations.

(d)

The amount of Damages recoverable by an Indemnified Party under this Article VIII shall be reduced by any proceeds received by such Indemnified Party or an Affiliate, with respect to the Damages to which such indemnity claim relates, from an insurance carrier or any third party. Each Indemnified Party shall use its Reasonable Best Efforts to seek payment or reimbursement for any Damages from its insurance carrier or other collateral sources. In the event that an Indemnified Party shall receive funds from any insurance carrier or collateral source with respect to any Damages, any such amounts so received shall be payable to the Indemnifying Party, regardless of

34

when received by the Indemnified Party, up to such amount previously paid by the Indemnifying Party or their Affiliates with respect to such Damages.

(e)
