1.05

Payment. Contemporaneously with the execution of this Agreement, Purchaser has deposited an amount equal to ten percent (10%) of the Purchase Price with JPMorgan Chase Bank, National Association, as escrow agent for the Parties (the “Escrow Agent”), to be deposited into an interest bearing account, such escrow arrangement to be governed by the

Houston3500259v15

5

Escrow Agreement, among WDR, Purchaser and the Escrow Agent, entered into contemporaneously herewith (the “Escrow Agreement”) (such amount, together with interest thereon, the “Deposit”). If Closing shall occur, Sellers and Purchaser agree that the Deposit shall be paid to Sellers (acting through WDR) by the Escrow Agent and shall be considered to have been applied toward the Purchase Price in accordance with Section 1.03.02(B). If Closing shall not occur by reason of the termination of this Agreement, the Deposit shall be applied in the manner set forth in Section 9.02. At the Closing, Purchaser shall wire transfer the Adjusted Purchase Price in immediately available funds as specified in writing by Sellers (acting through WDP) to Purchaser on the first (1^st) Business Day prior to the Closing Date.

1.06

Post Closing Review. On or prior to the one hundred twentieth (120^th) day after the Closing Date but no sooner than ninety (90) days after the Closing Date, Sellers shall cause WDP to present Purchaser with a final adjustment statement (the “Final Adjustment Statement”). Purchaser will give representatives of WDP reasonable access to its premises and to its books and records for purposes of preparing the Final Adjustment Statement and will cause appropriate personnel of Purchaser to provide reasonable assistance to WDP and WDP’s representatives, at no cost to Sellers, in the preparation of the Final Adjustment Statement. Sellers will give representatives of Purchaser and its representatives reasonable access to their premises and to their books and records for purposes of reviewing the Final Adjustment Statement. The Final A djustment Statement shall become final and binding on Sellers and Purchaser thirty (30) days following the date the Final Adjustment Statement is received by Purchaser, except to the extent that prior to the expiration of such thirty (30) day period Purchaser shall deliver to Sellers (acting through WDP) notice, as hereinafter described, of its disagreement with the contents of the Final Adjustment Statement. Such notice shall be in writing and set forth all of Purchaser’s disagreements with respect to any portion of the Final Adjustment Statement, together with Purchaser’s proposed changes thereto, and shall include an explanation in reasonable detail of, and such supporting documentation as is reasonably necessary and available to support, such changes. If Purchaser has timely delivered such a notice of disagreement to Sellers (acting through WDP), then, upon written agreement between Purchaser and Sellers (acting through WDP) resolving all disagreements of Purchaser set forth in such notice, the Final Adjustment Statement will become final and binding upon Purchaser and Sellers. If the Final Adjustment Statement has not become final and binding by the sixtieth (60th) day following its receipt by Purchaser, then Purchaser or Sellers (acting through WDP) may submit any unresolved disagreements of Purchaser set forth in such notice to a mutually agreeable arbitrator (which arbitrator must have at least ten (10) years of experience in oil and gas accounting matters in Louisiana and must not have performed any material accounting work for the preceding twelve (12) months for any Party) for binding arbitration, in which case the Party doing so must also immediately notify the other Party by telephone and facsimile. Any dispute regarding appointment of a mutually acceptable arbitrator shall be resolved by having Purchaser and Sellers (acting through WDP) each select one arbitrator meeting the criteria described above and instructing such two arbitrators to select a third arbitrator meeting the criteria described above. Such third arbitrator or a mutually acceptable arbitrator, as applicable, shall be referred to herein as the “Accounting Arbitrator”. The Accounting Arbitrator shall resolve disputes regarding any such adjustments within thirty (30) days of submittal by such Parties of the relevant materials for review taking into account, among other things, the likelihood the disputed item will cause either Purchaser or Sellers not to receive value bargained for under this Agreement and the length of time that the item has been treated by Sellers or their

Houston3500259v15

6

predecessors in the manner in which Sellers (acting through WDP) have asserted on the Final Adjustment Statement. Each Party agrees to pay all amounts due as a result of the agreement or the decision of the Accounting Arbitrator on the third (3^rd) Business Day thereafter. If payment is due for Sellers, the Seller that is an affiliate of WDP agrees to cause such payment to be timely made. In the event of a Subsequent Closing or an Environmental Subsequent Closing, the provisions of this Section 1.06 shall also apply thereafter as to the applicable Subject Properties only.

1.07

Ownership; Allocation of Revenues and Expenses. Subject to the other provisions of this Agreement, Sellers shall remain entitled to all of the rights of ownership of the Subject Properties (including, without limitation, the right to all production, proceeds of production and other proceeds) for the period of time prior to the Effective Date, and, after Closing, Purchaser shall be entitled to all of the rights of ownership of the Subject Properties (including, without limitation, the right to all production, proceeds of production and other proceeds) for the period of time on and after the Effective Date. Subject to the terms and conditions of this Agreement, revenues and expenses attributable to the Subject Properties shall be allocated as follows: (A) all expenses (including, without limitation, all drilling and completion costs, all capital expenditures, all ove rhead charges under applicable operating agreements and the amount of premiums under insurance policies maintained by WDP or Sellers) which are incurred in the operation of the Subject Properties before the Effective Date will be borne by Sellers and all proceeds (net of applicable production, severance, and similar taxes) from the sale of oil, gas and/or other minerals produced therefrom before the Effective Date will be owned by Sellers, and (B) all expenses (including, without limitation, all capital expenditures, all drilling and completion costs, all overhead charges under applicable operating agreements and the amount of premiums under insurance policies maintained by the operator of the Subject Properties) in connection with the operation of the Subject Properties after the Effective Date and paid or payable by Sellers under the applicable joint operating agreement will be borne by Purchaser and all proceeds (net of applicable production, severance, and similar taxes) from the sale of oil, gas an d/or other minerals produced therefrom after the Effective Date will be owned by Purchaser. It is agreed that, in making such allocations: (X) subject to Section 3.07, all oil which was produced from the Subject Properties and which was, on the Effective Date, stored in tanks located on the Subject Properties (or located elsewhere but used by Sellers to store oil produced from the Subject Properties prior to delivery to any oil purchaser) shall be deemed to have been produced before the Effective Date, and (Y) ad valorem taxes assessed with respect to a period of time which the Effective Date splits shall be prorated based on the number of days in such period of time which fall on each side of the Effective Date (with the day on which the Effective Date falls being counted in the period of time after the Effective Date).

1.08

Closing. The completion of the purchase and sale of the Subject Properties as contemplated by this Agreement, as well as the physical act or acts of execution and delivery of the documents contemplated hereby and delivery of consideration as provided above (the “Closing”) shall occur at the offices of WDP at a time mutually acceptable to Sellers and Purchaser on or before February 29, 2008 (the “Closing Date”).

1.09

Allocation of Purchase Price. Purchaser and Sellers agree that the entire Purchase Price (including any adjustments thereto) for the Subject Properties shall be allocated to "Class V assets" (as that term is defined in Treasury regulation section 1.338-6(b)(2)) in accordance with

Houston3500259v15

7

Section 1060 of the of the Code and the Treasury regulations thereunder.

6.03

Purchaser’s Title Review.

6.03.01

Purchaser’s Assertion of Title Defects. Purchaser shall promptly upon discovery notify Sellers (acting through WDP) in writing of any matters which, in Purchaser’s reasonable opinion, constitute Title Defects pursuant to this ARTICLE VI. Purchaser shall not be entitled to a Purchase Price adjustment for a Title Defect unless and until (i) the amount attributable to each Title Defect exceeds Thirty Thousand Dollars ($30,000) and (ii) all amounts attributable to all uncured Title Defects exceed One Million Dollars ($1,000,000) (the “Title Defect Threshold”) (at which time Purchaser shall be entitled to a Purchase Price adjustment for all amounts attributable to any Title Defect). Except for remedies for breach of Sellers’ special warranty in the Assignment and any breach by Sellers of Section 3.03.01(B)< /U>, for all purposes of this Agreement, Purchaser shall be deemed to have waived any Title Defect which Purchaser fails to assert as a Title Defect by written notice given to Sellers (acting through WDP) on or before 4:00pm Mountain Time on the thirtieth (30^th) day from the date of this Agreement (the “Defect Notice Date”). To be effective, Purchaser’s written notice of a Title Defect must include (i) a description of the matter constituting the asserted Title Defect sufficiently detailed to reasonably identify and explain the asserted Title Defect and the basis therefor, (ii) the claimed Title Defect Amount attributable thereto, (iii) supporting documents reasonably necessary for Sellers (as well as any title attorney or examiner hired by Sellers) to verify the existence of such asserted Title Defect and (iv) Purchaser's preferences, if any, as to the cure for such Title Defect. If Sellers effect the cure specified by Purchaser in its notice as the prefer red cure, then such Title Defect shall be deemed cured.

6.03.02

Purchase Price Allocations. If any adjustment is made to the Purchase Price pursuant to this Section 6.03, then a corresponding adjustment shall be made to the Allocated Value of the affected Subject Properties.

6.03.03

Sellers’ Opportunity to Cure. Sellers shall have until two (2) Business Days prior to the Closing Date, at their cost and expense, if Sellers so elect but without obligation, to cure all or a portion of such asserted Title Defect. If Sellers within such time fail to cure any Title Defect of which Purchaser has given timely written notice as required above and Purchaser has not and does not waive same on or before the day immediately preceding the Closing Date, the Subject Properties affected by such uncured and unwaived Title Defect shall be a “Title Defect Property”.

Houston3500259v15

24

6.03.04

Purchaser’s Title Adjustments. Subject to Section 6.05, in the event the Title Defect Threshold as to all uncured Title Defects is satisfied as finally determined by agreement between Sellers (acting through WDP) and Purchaser or arbitration according to the procedure set forth in Section 6.05, Purchaser shall be entitled to reduce the Purchase Price by the aggregate dollar amount of all Title Defects including, without limitation, those dollar amounts satisfying the Title Defect Threshold. Without prejudice to any other remedies under this Agreement, if the WI and NRI set forth on Exhibit “A” are incorrect due to the inclusion of any UMIs, then Purchaser shall be entitled to reduce the Purchase Price by the aggregate dollar amount of all Title Defects arising therefrom, without having to satisfy the Title Defect Thresho ld. “Title Defect Amount” shall mean, with respect to a Title Defect Property, the amount by which the value of such Title Defect Property is impaired as a result of the existence of one or more Title Defects, which amount shall be determined as follows:

(A)

If the Title Defect results from Sellers having a lesser NRI in such Title Defect Property than the NRI specified therefor on Exhibit “A”, the Title Defect Amount shall be equal to the product obtained by multiplying the Allocated Value of such Title Defect Property by a fraction, the numerator of which is the reduction in the NRI and the denominator of which is the NRI specified for such Title Defect Property on Exhibit “A”.

(B)

If the Title Defect results from Sellers having a greater WI in a Title Defect Property than the WI specified therefor on Exhibit “A”, then the Title Defect Amount shall be as agreed upon by the Parties.

(C)

If the Title Defect relates to failure of title to the entirety of Sellers’ title to a Subject Property, the maximum amount of the Title Defect Amount shall be the Allocated Value of such Subject Property on Exhibit “A”.

(D)

If the Title Defect results from the existence of a lien, security interest, pledge or collateral assignment upon one or more Subject Properties (or a portion thereof) which is liquidated in amount, the Title Defect Amount shall be an amount necessary to remove such lien, security interest, pledge or collateral assignment.

(E)

If the Title Defect results from any matter not described in paragraphs (A), (B), (C) or (D) above, the Title Defect Amount shall be an amount equal to the difference between the value of the Title Defect Property affected by such Title Defect with such Title Defect and the value of such Title Defect Property without such Title Defect (taking into account the Allocated Value of such Title Defect Property); provided that if such Title Defect is reasonably susceptible of being cured, the Title Defect Amount shall be the reasonable cost and expense of curing such Title Defect, if less.

(F)

A Title Defect shall not result from a clerical, typographical or mathematical error (including, without limitation, the erroneous listing of a Subject Property set forth on Exhibit “A” in which Sellers do not have an interest)

Houston3500259v15

25

in the computation of Sellers’ WI or NRI as set forth on Exhibit “A” and correction thereof would not be applied to the aggregate value of all Title Defects. Should such error be found, Purchaser shall be entitled to a reduction in the Purchase Price based on the Allocated Value of the affected Oil and Gas Properties. Such reduction in the Purchase Price shall not be subject to the Title Defect Threshold.

(G)

If a Title Defect is not effective or does not affect a Title Defect Property throughout the entire commercially productive life of such Title Defect Property, such fact shall be taken into account in determining the Title Defect Amount.

(H)

The Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder. For example, but without limitation, if a lien affects more than one Title Defect Property or the curative work with respect to one Title Defect results (or is reasonably expected to result) in the curing of any other Title Defect affecting the same or another Title Defect Property, the amount necessary to discharge such lien or the cost and expense of such curative work shall only be included in the Title Defect Amount for one Title Defect Property and only once in such Title Defect Amount.

(I)

If a Title Defect affects only a portion of a Subject Property (as contrasted with an undivided interest in the entirety of such Subject Property) and an Allocated Value has not been assigned specifically to such portion of a Subject Property, then for purposes of computing the Title Defect Amount, the portion of the Purchase Price allocated to such Subject Property shall be further allocated among the portions of such Subject Property as reasonably determined by Sellers (acting through WDP) and Purchaser.

(J)

The Title Defect Amount attributable to a Title Defect Property or any portion thereof shall not exceed the portion of the Purchase Price allocated to such Title Defect Property. For example, but without limitation, if Sellers do not own fifty percent (50%) of the NRI specified on Exhibit “A” for a Title Defect Property and such unowned fifty percent (50%) interest is also burdened by a lien, the Title Defect Amount for such Title Defect Property shall not exceed the portion of the Purchase Price allocable to such fifty percent (50%) interest notwithstanding that it may be affected by multiple Title Defects.

(K)

No Title Defect Amount shall be allowed on account of and to the extent that an increase in the Sellers’ WI in a Subject Property has the effect of proportionately increasing the Sellers’ NRI in such Subject Property.

6.04

Determination of Title Defects. A “Title Defect” shall exist if any Seller does not have Defensible Title with respect to all or a portion of one or more Subject Properties.

Houston3500259v15

26

6.05

Disputes. If Purchaser and Sellers (acting through WDP) have not agreed upon (i) the existence of a Title Defect, (ii) whether a Title Defect is cured or (iii) the Title Defect Amount, adjustments, credits or offsets claimed by Purchaser pursuant to and in accordance with the requirements of this ARTICLE VI (in each case) within two (2) Business Days prior to Closing, then either Purchaser or Sellers (acting through WDP) may submit such claim (an “Adjustment Claim”) on or after such second (2^nd) Business Day to a mutually agreeable arbitrator (which arbitrator must have at least ten (10) years of experience in oil and gas title matters in northern Louisiana and must not have performed any title work for any Party with respect to the Oil and Gas Property for which the Title Defect at issue has been asserted) for binding arbitration, in which case the Party doing so must also immediately notify the other Party by telephone and facsimile. Any dispute regarding appointment of a mutually acceptable arbitrator shall be resolved by having Purchaser and Sellers (acting through WDP) each select one arbitrator meeting the criteria described above and instructing such two arbitrators to select a third arbitrator meeting the criteria described above. Such third arbitrator or a mutually acceptable arbitrator, as applicable, shall be referred to herein as the “Title Arbitrator”. If either or both of Purchaser and Sellers (acting through WDP) wish to submit statements of their position and supporting documentation to the Title Arbitrator, then it must do so within five (5) Business Days after appointment of the Title Arbitrator, and such Party transmit by identical means a copy of its submission to the other Party. The Title Arbitrator shall resolve the dispute within twenty (20) days after his appointment . The Title Arbitrator shall resolve each Adjustment Claim in accordance with the requirements of this Agreement and based on applicable Law, and as to an Adjustment Claim involving matters addressed by Section 6.03.04(B), the Title Arbitrator shall engage and rely upon the advice of a reservoir engineer who is experienced in net present value calculations and who has not performed any work with respect to the Subject Properties for any Party, and such reservoir engineer shall be required to utilize a discount rate of 10% compounded annually in such net present value calculations. The decision of the Title Arbitrator shall be final and binding and shall not be subject to appeal by the Parties to any court that may otherwise have jurisdiction. Fees and expenses of the Title Arbitrator shall be borne equally by the Parties.

6.06

Effect on Closing.

6.06.01

At Closing, the Title Defect Properties will not be sold or bought, the Purchase Price will be reduced as described in Section 1.03.02(C) by the Title Defect Amount, the Title Defect Amount will be deposited by Purchaser with the Escrow Agent subject to the Escrow Agreement and title to such Title Defect Properties will remain with Sellers until the Title Arbitrator’s determination is made.

6.06.02

Two (2) Business Days after an Adjustment Claim as to a Title Defect Property is resolved either through mutual agreement of the Parties or by the Title Arbitrator (except with respect to any Title Defect Property as to which it is determined that Sellers had no title whatsoever), the Parties shall close on the sale of such Title Defect Property (a “Subsequent Closing”), subject to the conditions of ARTICLE IV, which shall apply as to such Subsequent Closing with respect to only such Subject Properties as are conveyed therein. At each Subsequent Closing, the Parties shall take such actions and make such deliveries as apply to Closing with respect to such Title Defect Property except that instead of Purchaser making a payment, Purchaser and

Houston3500259v15

27

Sellers (acting through WDR) shall cause the Escrow Agent to deliver the applicable Title Defect Amount (plus any accrued interest and adjusted in accordance with Section 1.03 as it applies to the applicable Title Defect Property only) to the Parties in accordance with their agreement or the determination of the Title Arbitrator, as the case may be. If it is determined with respect to any Title Defect Property that Sellers had no title whatsoever, then Purchaser and Sellers (acting through WDR) shall cause the Escrow Agent to deliver the applicable Title Defect Amount (plus any accrued interest) to Purchaser, and the obligations of the Parties under this Agreement with respect thereto shall cease.

6.06.03

During the period of time between the Closing and a Subsequent Closing, the provisions of this Agreement relating to any period of time prior to Closing shall continue to apply as to the applicable Title Defect Property.

6.06.04

Notwithstanding anything herein provided to the contrary, if any matter results both in a Title Defect and a breach of any representation or warranty of Sellers set forth in this Agreement, then Purchaser shall only be entitled to assert such matter (to the extent such matter could result both in a Title Defect and a breach of any representation or warranty of Sellers set forth in this Agreement) as a Title Defect pursuant to this Article VI and shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty.

ARTICLE VII

7.06

Indemnification Procedures.

7.06.01

Promptly after any Party (the “Indemnified Party”) becomes actually aware of facts giving rise to a right to bring a Claim by it for indemnification pursuant to this ARTICLE VII, and prior to the expenditure or approval of the expenditure of any substantial funds, such Indemnified Party will provide notice thereof in writing (a “Claim Notice”) to the Party owing such indemnification (the “Indemnifying Party”) specifying the nature and specific basis for such Claim and a copy of all papers served with respect to such Claim (if any). For purposes of this Section 7.06, receipt by the Indemnified Party of written notice of any demand, assertion, claim, action or proceeding (judicial, administrative or otherwise) by or from any Person other than a Party to this Agreement or any affiliate t hereof which gives rise to a Claim on behalf of such Party shall constitute awareness of a Claim by it and shall require prompt notice of the receipt of such matter as provided in the first sentence of this Section. Each Claim Notice shall set forth a reasonable description of the Claim and shall contain a statement to the effect that the Indemnified Party is making a Claim pursuant to and formal demand for indemnification under, this ARTICLE VII. The Claim Notice must set forth the particular provision in this ARTICLE VII and any related provision in this Agreement pursuant to which such Claim is made.

7.06.02

The indemnifications provided by this Agreement are expressly subject to the following:

(A)

In case any legal proceeding, including, without limitation, any investigatory proceeding, is brought or made against the Indemnified Party in a manner for which indemnification may be provided under Section 7.02 or Section 7.04, the Indemnified Party shall promptly notify the Indemnifying Party with the delivery of the Claim Notice. The Indemnifying Party shall have the right to

Houston3500259v15

30

control and assume the defense of any such proceeding, including, without limitation, the employment of counsel satisfactory to the Indemnifying Party. If the Indemnifying Party controls and assumes the defense of such proceeding, the Indemnified Party shall have the right to employ separate counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless the representation of both the Indemnified Party and the Indemnifying Party by the same counsel would be inappropriate due to any actual or potential conflicts of interest. The Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys at any one time for the Indemnified Parties in connection with any one legal proceeding.

(B)

Notwithstanding anything to the contrary in Section 7.06.02(A), the Indemnified Party shall be entitled to reasonable compensation of costs of defense, including, without limitation, reasonable attorneys fees, in the event that (i) the employment of separate counsel has been authorized by the Indemnifying Party, (ii) the Indemnifying Party has failed to defend diligently any Claims, or (iii) the parties to such action (including, without limitation, any impleaded parties) include the Indemnified Party and the Indemnifying Party, and the Indemnified Party has been advised by legal counsel that there may be legal defenses available to it which are different from, in addition to or inconsistent with, the legal defenses available to the Indemnifying Party, or that the Indemnified Party’s interest may be adverse in whole or in part to the interest o f the Indemnifying Party (subject to the last sentence of Section 7.06.02(A)). The Indemnifying Party shall not, in the defense of any such Claims, except with the prior written consent of the Indemnified Party, consent to the entry of any judgment or enter into any settlement which does not include, as an unconditional term, the release by the claimant or the plaintiff of the Indemnified Party from all liability in respect to any such Claims.

7.06.03

The indemnification obligations under this ARTICLE VII (or otherwise under this Agreement) shall not apply to any settlements effected without the consent of the Indemnifying Party. The indemnification obligations under this ARTICLE VII (or otherwise under this Agreement) shall not be deemed to create any rights of subrogation or other rights in any insurer or third party. Any failure to promptly notify the Indemnifying Party in accordance with this Section 7.06 with respect to a Claim brought against or sought to be collected from or by the Indemnified Party will not relieve such Indemnifying Party from any liability which it may have to such Indemnified Party except to the extent (and then only to such extent) that such failure to so notify such Indemnifying Party has materially prejudiced the Indemnifying Party.

ARTICLE VIII
LIMITATIONS OF LIABILITY

8.01

Except for Sellers’ indemnification obligations under Section 7.04 (other than those that have terminated pursuant to the foregoing sentence) or for breaches of representations and warranties that survive lon ger pursuant to the foregoing sentence, on and after one (1) year from the Closing, Purchaser shall not be entitled to make any claim against Sellers with respect to the Subject Properties or the purchase and sale thereof for any cause attributable to any period of time under this Agreement or otherwise, including, without limitation, rights of contribution arising under or based on any Law and, except for Sellers’ indemnification obligations under Section 7.04 (other than those that have terminated pursuant to the foregoing sentence) or for breaches of representations and warranties that survive longer pursuant to the foregoing sentence, any and all liabilities of Sellers under this Agreement for which Purchaser has not previously delivered to Sellers a Claim Notice pursuant to Section 7.06.01 shall be deemed Assumed Obligations.

9.01

Termination of Agreement. This Agreement and the transactions contemplated hereby may be terminated by Sellers (by written notice to Purchaser) or by Purchaser (by written notice to Sellers) as follows:

9.01.01

By Sellers, if the conditions set forth in Section 4.01 are not satisfied in all respects or waived as of Closing.

9.01.02

By Sellers or Purchaser, if at or before Closing, the aggregate sum of the Title Defect Amounts for all Title Defects and Environmental Defect Values for all Environmental Conditions equals or exceeds twenty percent (20%) of the Purchase Price.

9.01.03

9.01.04

9.02

Liabilities Upon Termination. If this Agreement is terminated prior to Closing for any reason other than those set forth in Section 9.01 or is breached (provided that it shall be deemed a breach of this Agreement if the conditions set forth in Section 4.02 are not satisfied through the fault, neglect or failure to act of Purchaser, or if the conditions set forth in Section 4.01 are not satisfied through the fault, neglect or failure to act of Sellers), then (A) if terminated because of a breach by Purchaser of this Agreement, Sellers shall be entitled to the Deposit as their sole and exclusive remedy (the Parties hereby agreeing that the damages suffered by Sellers would be difficult to measure and the Deposit represents a fair approximation of such damages by the Parties), and (B) if termina ted because of a breach by Sellers of this Agreement, Purchaser shall be entitled to a return of the Deposit and shall be permitted to pursue all remedies at law or in equity for such breach; provided, however, that the Parties agree that the maximum liability of Sellers’ breach, in addition to the return of the Deposit, shall be Fifty Nine Million Six Hundred Seventy Eight Thousand Dollars ($59,678,000). Notwithstanding anything herein to the contrary, the provisions of this Section 9.02, Section 10.01.02 and ARTICLE XI shall survive any termination of this Agreement.

ARTICLE X
ENVIRONMENTAL ASSESSMENT

10.01

Environmental Assessment.

10.01.01

Inspection and Testing. Prior to Closing, Purchaser will have the right, at its sole cost, risk and expense, to have its agents or representatives (the “Inspector”) conduct a Phase I environmental assessment of the Subject Properties. For

Houston3500259v15

33

the purposes of this Agreement, a “Phase I environmental assessment” may include one or more of the following: (i) a review of the records of Sellers and Governmental Authorities, (ii) the submission of pre-inspection questionnaires to Sellers, (iii) a site visit to visually inspect the Subject Properties and (iv) interviews with corporate and site personnel of Sellers. Should the results of the Phase I environmental assessment reasonably warrant, in the sole opinion of Purchaser, a Phase II environmental assessment or any other soil or groundwater sampling and analysis or any other subsurface testing, then Purchaser shall be permitted to proceed with such actions but shall provide Sellers with prior notice and shall provide Sellers the opportunity to be present for such actions.

10.01.02

Inspection and Test Results. Sellers (acting through WDP) will be entitled to receive a copy of the results of the Phase I environmental assessment and Phase II environmental assessment for the Subject Properties, including, without limitation, all written reports, data and conclusions of the Inspector. Purchaser agrees (unless and until Closing) not to disclose such results of the Phase I environmental assessment and Phase II environmental assessment for the Subject Properties, or any information of Sellers reviewed during the Phase I environmental assessment and Phase II environmental assessment for the Subject Properties, to third parties without the agreement of Sellers (acting through WDP), except as required by the arbitration procedure in Section 10.03.03, applicable Law or by the order of a court or regulatory agency. This Section 1 0.01 shall survive the termination of this Agreement for any reason.

10.02

Notice of Environmental Conditions. Prior to the Defect Notice Date, Purchaser will review the inspection and testing results for the Subject Properties and determine based on those results whether any Environmental Conditions exist with respect to the Subject Properties. No later than 4:00pm Mountain Time on the Defect Notice Date, Purchaser will notify Sellers in writing of any Environmental Conditions adversely affecting the value of the Subject Properties. Such notice shall describe in reasonable detail the Environmental Conditions, include all data and information in Purchaser’s or its Inspector’s possession or control bearing thereon and include the estimated Environmental Defect Values attributable thereto, to the extent the Environmental Defect Values are known.

10.03

Right and Remedies for Environmental Conditions.

10.03.01

Purchaser shall not be entitled to a Purchase Price adjustment or other remedy for the Environmental Conditions affecting the Subject Properties, unless (i) the Environmental Defect Value attributable to each un-Remediated Environmental Condition exceeds Thirty Thousand Dollars ($30,000) and (ii) all Environmental Defect Values attributable to all un-Remediated Environmental Conditions exceed One Million Dollars ($1,000,000) (the “Environmental Threshold Amount”), it being agreed that Purchaser shall be solely responsible for each Environmental Condition for which the Environmental Defect Value is less than or equal to Thirty Thousand Dollars ($30,000).

10.03.02

If all Environmental Defect Values attributable to all Environmental Conditions exceed the Environmental Threshold Amount, then Purchaser, at its sole option and discretion, with regard to those Environmental Conditions for which the

Houston3500259v15

34

Environmental Defect Values exceed Thirty Thousand Dollars ($30,000), may (i) request that Sellers Remediate such Environmental Conditions, but Sellers will have no obligation to Remediate the Environmental Conditions or (ii) request a reduction in the Purchase Price equal to the applicable Environmental Defect Values. In the event the Environmental Threshold Amount for all un-Remediated Environmental Conditions is satisfied as finally determined by agreement between Sellers (acting through WDP) and Purchaser or arbitration, Purchaser shall be entitled to reduce the Purchase Price by the aggregate dollar amount of all Environmental Defect Values attributable to all un-Remediated Environmental Conditions, including, without limitation, those dollar amounts satisfying the Environmental Threshold Amount. If Sellers (acting through WDP) agree to Remediate the Environmental Conditions, nothing contained in this Agreement shall prevent Sellers from recovering pursuant to existing agreements or to statutory or common law contribution rights a proportionate share, based upon relative working or other cost bearing interests, of the costs of Remediation from other Persons who own interests in the Subject Properties affected by the Environmental Conditions. If Sellers (acting through WDP) and Purchaser are unable to agree no later than two (2) Business Days before Closing on curative measures or a reduction in the Purchase Price with respect to any such Environmental Conditions, then the Parties will have the rights and remedies set forth in Section 10.03.03.

10.03.03

The rights and remedies of Sellers and Purchaser with respect to an Environmental Condition on a Subject Property with respect to which Sellers (acting through WDP) and Purchaser are unable to agree on or before two (2) Business Days prior to Closing on curative measures or a Purchase Price reduction (a “Disputed Adverse Environmental Condition”) are as set forth in this Section. As to each Disputed Adverse Environmental Condition, the Parties shall negotiate in good faith to agree on curative measures or a Purchase Price reduction. If the Parties are unable to agree on whether an Environmental Condition exists, curative measures or a Purchase Price reduction, then, at the sole option and discretion of Purchaser (i) the affected Subject Property will be removed from the transaction and the Purchase Price shall be reduced by the Alloc ated Value of such Subject Property or (ii) the Subject Properties with such Disputed Adverse Environmental Condition will not be sold or bought, the Purchase Price will be reduced as described in Section 1.03.02(C) by the Allocated Value attributable to such Subject Properties, such Allocated Value will be deposited by Purchaser with the Escrow Agent subject to the Escrow Agreement and title to such Subject Properties will remain with Sellers until the Environmental Arbitrator’s determination is made. Either Sellers (acting through WDP) or Purchaser shall have the right, exercisable within ninety (90) days after the Closing Date, to submit all Disputed Adverse Environmental Conditions to binding arbitration before a mutually agreeable arbitrator (which arbitrator must have at least ten (10) years of experience in oil and gas environmental compliance matters and must not have performed any environmental work for any Party with respect to the Subject Properties affected by the Disputed Adver se Environmental Conditions). Any dispute regarding appointment of a mutually acceptable arbitrator shall be resolved by having Purchaser and Sellers (acting through WDP) each select one arbitrator meeting the criteria described above and instructing such two arbitrators to select a third arbitrator meeting the criteria described above. Such third arbitrator or a mutually acceptable arbitrator, as applicable, shall be referred to herein as the “Environmental Arbitrator”.

Houston3500259v15

35

The Environmental Arbitrator shall resolve the dispute within thirty (30) days of submittal of the relevant documentation by the Parties. The decision of the Environmental Arbitrator is final and binding upon the Parties and is not subject to appeal by the Parties to any court that may otherwise have jurisdiction. Fees and expenses of the Environmental Arbitrator shall be borne equally by the Parties.

10.03.04

If any Subject Property with Disputed Adverse Environmental Conditions was excluded from Closing pursuant to Section 10.03.03(ii), then two (2) Business Days after such Disputed Adverse Environmental Conditions as to such Subject Property were resolved either through mutual agreement of the Parties or by the Environmental Arbitrator, the Parties shall close on the sale of such Subject Property (an “Environmental Subsequent Closing”), subject to the conditions of ARTICLE IV, which shall apply as to such Environmental Subsequent Closing with respect to only such Subject Properties as are conveyed therein. At each Environmental Subsequent Closing, the Parties shall take such actions and make such deliveries as apply to Closing with respect to such Subject Property except that instead of Purchaser making a payment, Purchaser and Seller s (acting through WDR) shall cause the Escrow Agent to deliver the applicable Allocated Value (plus any accrued interest and adjusted in accordance with Section 1.03 as it applies to the applicable Subject Property only) to the Parties in accordance with their agreement or the determination of the Environmental Arbitrator, as the case may be.

10.03.05

During the period of time between the Closing and an Environmental Subsequent Closing, the provisions of this Agreement relating to any period of time prior to Closing shall continue to apply as to the applicable Subject Properties affected by Environmental Conditions.

10.03.06

The term “Remediation” or “Remediate” means, with respect to any Environmental Condition, the undertaking and completion of those actions and activities necessary to remediate such Environmental Condition to the degree necessary such that the Environmental Condition no longer constitutes an Environmental Condition. Sellers shall cause WDP to promptly notify Purchaser at such time as it believes Sellers have Remediated an Environmental Condition. Purchaser shall promptly notify Sellers (acting through WDP) of whether it agrees such condition is Remediated. If Purchaser fails to notify Sellers (acting through WDP) of whether it agrees such condition was Remediated within two (2) Business Days following receipt of WDP’s notice, such Environmental Condition shall be deemed Remediated. If Sellers (acting through WDP) and Purchaser are unable to agree that an Environmental Condition has been Remediated, either Party may submit such issue to arbitration pursuant to the terms of Section 10.03.03. Notwithstanding any agreement by Sellers (acting through WDP) to attempt to Remediate the Environmental Conditions or to reduce the Purchase Price due to Environmental Conditions, to the extent the involved Subject Properties are accepted by Purchaser, Purchaser assumes the identified Environmental Conditions with respect to such involved Subject Properties. Such assumption of Environmental Conditions shall not relieve Sellers of their obligations to Remediate the Environmental Condition they agreed to Remediate under the foregoing provisions.

Houston3500259v15

36

10.03.07

The term “Environmental Condition” means (a) the failure of a Subject Property to be in compliance with all applicable federal, state, and local laws, including, without limitation, statutes, regulations, orders, ordinances, and common law, relating to the protection of the public health, welfare and the environment, including, without limitation, those laws relating to the storage, handling, and use of chemicals and other hazardous materials, those relating to the generation, processing, treatment, storage, transportation, disposal, or other management of waste materials of any kind (“Environmental Law”), (b) a Subject Property being subject to any agreements, orders, decrees, settlements, directives, injunctions, or judgments currently in existence based on any Environmental Law that require any Person to Remediate a Subject Property or negatively impact in an adverse and material manner (such as a material increase in costs or a material decrease in revenues or a diminution in value) the present or the future use of any portion of a Subject Property or (c) a Subject Property being subject to any un-Remediated notices of violations of or non-compliance with any applicable Environmental Law.

10.03.08

The term “Environmental Defect Value” means Purchaser's reasonable estimate of the cost of Remediating an Environmental Condition and any and all damages or costs arising out of or related to such Environmental Condition.

Each Seller reserves the right, at or prior to Closing, to assign its rights under this Agreement with respect to all or a portion of the Purchase Price, and that portion of the Subject Properties being sold by such Seller hereunder associated therewith (“1031 Assets”), to a Qualified Intermediary (“QI”) (as that term is defined in Section 1.1031(k)-l(g)(4)(v) of the Treasury Regulations) designated by such Seller to accomplish the Closing, in whole or in part, in a manner that will comply with the requirements of a like-kind exchange (“Like-Kind Exchange”) pursuant to Section 1031 of the Internal Revenue Code of 1986, as amended (“Code”). If a Seller so elects, then such Seller may assign its rights under this Agreement to the 1031 Assets to the QI.

Houston3500259v15

41

Purchaser hereby (i) consents to such Seller’s assignment of its rights in this Agreement with respect to the 1031 Assets and (ii) if such assignment is made, agrees to pay all or a portion of the Purchase Price (as adjusted pursuant hereto) to which such Seller is entitled (as directed by WDP) into the qualified trust account at Closing as directed in writing by such Seller. Such Seller and Purchaser acknowledge and agree that a whole or partial assignment of this Agreement to a QI shall not release any Party from any of its liabilities and obligations hereunder. No Party represents to the other Parties that any particular tax treatment will be given to a Party as a result of such Like-Kind Exchange. Purchaser shall cooperate with such Seller in connection with such Like-Kind Exchange but shall not be obligated to pay any additional costs or incur any additional o bligations as a result thereof and any such Seller shall indemnify, defend and hold harmless Purchaser for any and all costs or expenses incurred in connection therewith or as a result thereof.

11.15.02

Purchaser shall have the right to request that a Seller assign all or any portion of the Subject Properties being sold by such Seller hereunder to a QI designated by Purchaser in order for such QI to effect a Like-Kind Exchange for Purchaser with respect to such Subject Properties or portion thereof. Such assignment of such Subject Properties or portion thereof shall not release any Party from any of its liabilities and obligations hereunder. No Party represents to the other Parties that any particular tax treatment will be given to a Party as a result of such Like-Kind Exchange. Sellers shall cooperate with Purchaser in connection with such Like-Kind Exchange but shall not be obligated to pay any additional costs or incur any additional obligations as a result thereof, and Purchaser shall indemnify, defend and hold harmless Sellers for any and all co sts or expenses incurred in connection therewith or as a result thereof.

11.16

Casualty. An event of casualty means volcanic eruptions, acts of God, terrorist action, fire, explosion, earthquake, wind storm, flood, drought, condemnation, the exercise of any right of eminent domain, confiscation, seizure or other casualty loss (a “Casualty”).

11.16.01

If, prior to Closing, one or more Casualties occur which result in a reduction in the value of the Subject Properties in excess of twenty percent (20%) of the Purchase Price (“Casualty Loss”), Purchaser or Sellers may elect to terminate this Agreement.
