B. Buyer has conducted and will continue to conduct an independent investigation of the nature and extent of the Assets (as defined below) and desires to purchase all of Seller's interest in the Assets pursuant to the terms of this Agreement.

C. To accomplish the foregoing, the Parties wish to enter into this Agreement.

AGREEMENT

In consideration of the mutual promises contained herein, $100 and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Buyer and Seller agree as follows:

ARTICLE 1
PURCHASE AND SALE

1.1 Purchase and Sale.

Seller agrees to sell and Buyer agrees to purchase all of Seller's right, title and interest in the Assets as set forth below, all pursuant to the terms of this Agreement.

1.2 The Assets.

As used herein, the term "Assets" refers to all of Seller's right, title and interest in and to the following, excluding however the Excluded Assets (as defined below):

A. The oil, gas and/or mineral leases and fee mineral interests specifically described in Exhibit A‑1 (the "Leases"), including without limitation all leasehold estates and interests, all royalty, overriding royalty, production payment, reversionary, net profit, contractual working interests and other similar rights and estates therein, the lands described in Exhibit A‑1 (the "Lands") and the oil, gas and other hydrocarbons ("Hydrocarbons") attributable to the Leases or Lands, including all rights in any pooled, unitized or communitized acreage by virtue of the Lands or Leases being a part thereof and all Hydrocarbons produced from the pool or unit allocated to any such Lands or Leases;

B. The wells specifically described in Exhibit B (the "Wells"), together with all other oil and gas wells and all water, injection and disposal wells on the Lands or on lands pooled, communitized or unitized therewith, and all personal property, equipment, fixtures, improvements, permits, water discharge permits, rights-of-way and easements (including without limitation the rights‑of-way and easements described on Exhibit A‑2) located on the Lands or used in connection with the production, gathering, treatment, processing, storing, transportation, sale or disposal of Hydrocarbons or water produced from the properties and interests described in Section 1.2 A.;

C. The unitization, pooling and communitization agreements, declarations and orders, and the units created thereby, all operating agreements and unit operating agreements and all other such agreements relating to the properties and interests described in Sections 1.2 A. and B. and to the production of Hydrocarbons, if any, attributable to said properties and interests, including those which are described in Exhibit C;

D. All existing and effective sales, purchase, exchange, gathering and service agreements and other contracts, agreements and instruments which relate, and only insofar as they relate, to the properties and interests described in Sections 1.2 A. through C., and including those which are described in Exhibit C;

E. All original files, records and data, including without limitation lease and well files, abstracts, title reports, memoranda and opinions, relating to the items described in Sections 1.2 A. through 1.2 D. maintained by Seller, but excluding (i) Seller's company files, financial records, and tax related records to the extent not relevant to the Assets, and (ii) records and data to the extent transfer thereof is prohibited by unaffiliated third party contractual restrictions on transfer (the "Records"). To the extent that any of the Records contain interpretations of Seller, Buyer agrees to rely on such interpretations at its own risk.

1.3 Excluded Assets.

Seller is selling its interest in the Assets, but is not selling and is retaining its interest in and to the Excluded Assets. As used herein, the term "Excluded Assets" refers to all of Seller's right, title, and interest in and to the following:

A. All company records and files, including tax related records, to the extent not directly related to the Assets; and

B. Any Asset excluded from this Agreement pursuant to Sections 4.5A and 4.5B.1 of this Agreement.

1.4 Effective Time.

The purchase and sale of the Assets shall be effective as of October 1, 2006, at 7:00 a.m. local time at the location of the Assets (the "Effective Time").

1.5 1031 Exchange.

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 Assets associated therewith ("1031 Assets"), to a Qualified Intermediary ("QI") (as that term is defined in Section 1.1031(k)-1(g)(4)(v) of the Treasury Regulations) to accomplish this Transaction, 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"). Buyer reserves the right, at or prior to Closing, to assign its rights under this Agreement and all or a portion of the Assets ("1031 Assets") to a QI. If Seller or Buyer so elects, Seller or Buyer may assign its rights under this Agreement to the applicable 1031 Assets to the QI. Each Party hereby (i) consents to the other Party's assignment of its rights in this Agreement with respect to the applicable 1031 Assets, and (ii) if such an assignment is made by Seller, Buyer agrees to pay all or a portion of the Purchase Price into the qualified trust account at Closing as directed in writing by Seller. Each Party agrees to take all actions reasonably required of it, including, but not limited to, executing and delivering documents, to permit the other Party to effect the exchange described in this Section. The Parties acknowledge and agree that a whole or partial assignment of this Agreement to a QI shall not release either Party from any of its respective liabilities and obligations to the other Party or expand any liabilities or obligations of the other Party under this Agreement. Neither Party represents to the other that any particular tax treatment will be given to the other Party as a result of the Like-Kind Exchange. Neither Party shall be obligated to pay any additional costs or incur any additional obligations under this Agreement if such costs are the result of the other Party's Like-Kind Exchange, and each Party shall hold harmless and indemnify the other Party from and against all claims, losses and liabilities (including reasonable attorneys' fees, court costs and related expenses), if any, resulting from such a Like-Kind Exchange.

ARTICLE 2
PURCHASE PRICE

2.1 Purchase Price.

The purchase price for the Assets shall be $132,500,000.00 (the "Purchase Price"). At Closing, Buyer shall pay Seller the Purchase Price, as adjusted pursuant to Section 2.4.

Contemporaneously with the execution of this Agreement, the Parties and Wells Fargo Bank, National Association (the "Escrow Agent") have entered into an escrow agreement (the "Escrow Agreement"), attached hereto as Exhibit L, pursuant to which Buyer has deposited in cash $500,000.00 (the "Deposit") in an escrow account with Escrow Agent (the "Escrow Account"). Under the terms of the Escrow Agreement, the Escrow Agent shall distribute the Deposit as set forth in Articles 11 and 12.

2.3 Allocation of the Purchase Price.

Buyer and Seller have allocated the Purchase Price among the Assets as set forth on Exhibit B. The value so allocated to a particular Asset may be referred to as the "Allocated Value" for that Asset.

A. Settlement Statements.

The Purchase Price shall be adjusted at Closing pursuant to a "Preliminary Settlement Statement" prepared by Seller, submitted to Buyer on or before five business days prior to Closing, for Buyer's comment and review. The Preliminary Settlement Statement shall set forth the Closing Amount and all adjustments to the Purchase Price and associated calculations. The term "Closing Amount" means the Purchase Price, adjusted as provided in this Section using reasonable estimates as agreed to by the Parties if actual numbers are not available. After Closing, the Purchase Price shall be adjusted pursuant to the Final Settlement Statement delivered pursuant to Section 13.1.

B. Property Expenses.

For the purposes of this Agreement, the term "Property Expenses" shall mean all capital expenses, joint interest billings, lease operating expenses, Taxes (as defined and apportioned as of the Effective Time pursuant to Article 9), drilling expenses, workover expenses, geological, geophysical and any other exploration or development expenditures chargeable under applicable operating agreements or other agreements consistent with the standards established by the Council of Petroleum Accountant Societies of North America that are attributable to the maintenance and operation of the Assets during the period in question.

C. Effective Time Apportionment of Property Expenses and Revenues.

Buyer and Seller agree that all revenues, costs and expenses (both operating and capital), including Property Expenses related to the Assets will be apportioned between Buyer and Seller as of the Effective Time. Accordingly, (i) Seller shall be entitled to any production revenues or other amounts realized from and accruing to the Assets attributable to the period of time before the Effective Time, and shall be liable for the payment of all costs and expenses, including Property Expenses, royalties, overriding royalties, lease rental and maintenance costs and leasehold payments attributable to the Assets for the period of time before the Effective Time; and (ii) Buyer shall be entitled to any production revenues or other amounts realized from and accruing to the Assets attributable to the period of time after the Effective Time, and shall be liable for the payment of all costs and expenses, including Property Expenses, royalties, overriding royalties, lease rental and maintenance costs and leasehold payments attributable to the Assets for the period of time after the Effective Time.

D. Upward Adjustments.

The Purchase Price shall be adjusted upward by the following:

1. An amount equal to all proceeds (net of royalty and Taxes not otherwise accounted for hereunder) received and retained by the Buyer from the sale of all Hydrocarbons produced from or credited to the Assets prior to the Effective Time;

2. An amount equal to all direct and actual expenses attributable to the Assets, including, without limitation, the Property Expenses, incurred and paid by Seller that are attributable to the period after the Effective Time;

3. To the extent not covered in the preceding paragraph, an amount equal to all prepaid expenses attributable to the Assets after the Effective Time that were paid by or on behalf of Seller, including without limitation, prepaid drilling and/or completion costs and prepaid utility charges;

4. An amount equal to the value (net of applicable Taxes) of Seller's share of all oil in storage tanks above the pipeline interconnect at the Effective Time to be calculated as follows: The value shall be the product of (i) the volume in each storage tank (attributable to Seller's interest) as of the Effective Time as shown by the actual gauging reports, multiplied by (ii) the price actually received for October 2006 production under the applicable marketing contract if the Hydrocarbons in question had been sold; provided, however, that the adjustment contemplated by this subsection shall be made only to the extent that Seller does not receive and retain the proceeds, or portion thereof, attributable to the pre-Effective Time merchantable oil in the storage tanks;

5. Any amount equal to the value of Additional Interest pursuant to subsection 4.2 C.

6. Any other amount agreed to by Buyer and Seller.

E. Downward Adjustments.

The Purchase Price shall be adjusted downward by the following:

1. Proceeds received and retained by Seller (net of applicable Taxes and royalties) that are attributable to production from the Assets after the Effective Time;

2. The amount of all direct and actual expenses attributable to the Assets, including, without limitation, the Property Expenses, that remain unpaid by Seller, or that have been paid by Buyer, that are attributable to the period prior to the Effective Time;

3. An amount equal to adjustments for Title Defects, Environmental Defects, Casualty Losses and Exclusion Adjustments, and other adjustments as set forth in this Agreement; and

4. Any other amount agreed to by Buyer and Seller.

F. Gas Imbalances.

In addition to the foregoing, the Purchase Price shall be adjusted downward or upward, as appropriate, by an amount equal to $4.00 per MCF for the well and pipeline gas imbalances existing as of the Effective Time, as further outlined on Exhibit P (the "Gas Imbalance Schedule"). The Purchase Price shall be adjusted in the Settlement Statement with respect to the imbalance volumes. If there is a dispute concerning the confirmation and adjustment of the imbalance volumes, the Parties agree to submit such dispute to binding arbitration pursuant to the provisions of Section 14.7.

ARTICLE 3
BUYER'S INSPECTION

3.1 Access to the Records.

Prior to Closing and subject to Section 8.3, Seller will make the Records available to Buyer for inspection, copying, and review at Seller's offices during normal business hours to permit Buyer to perform its due diligence review. Subject to the consent and cooperation of third parties, Seller will assist Buyer in Buyer's efforts to obtain, at Buyer's expense, such additional information from such parties as Buyer may reasonably desire. Buyer may inspect the Records and such additional information only to the extent it may do so without violating any obligation of confidence or contractual commitment of Seller to a third party.

3.2 Disclaimer.

Except for the representations contained in this Agreement, Seller makes no representation of any kind as to the Records or any information contained therein. Buyer agrees that any conclusions drawn from the Records shall be the result of its own independent review and judgment.

3.3 Physical Access to the Leases, Lands and Wells.

Upon reasonable notice and during reasonable business hours, Seller agrees to grant Buyer physical access to the Leases, Lands and Wells to allow Buyer to conduct, at Buyer's sole risk and expense, on-site inspections and environmental assessments of the Leases, Lands and Wells. In connection with any such on-site inspections and assessments, Buyer agrees not to interfere with the normal operation of the Leases and Wells and agrees to comply with all operational and safety requirements of the operators of the Wells. If Buyer or its agents prepares an environmental assessment of any Lease, Lands or Well, Buyer agrees to keep such assessment confidential and to furnish copies thereof to Seller. Such information shall be held confidential but may be disclosed to Buyer or Buyer's affiliates, attorneys, officers, employees and consultants used in Buyer's evaluation of Seller's properties. Furthermore, Buyer's obligations of confidentiality shall not apply to information (i) required to be disclosed by legal process, order, regulation, or rule, or (ii) available to the public, or (iii) acquired from third parties not known by Buyer to have confidentiality obligations to Seller. In connection with granting such access, Buyer represents that it is adequately insured and waives, releases and agrees to indemnify Seller, and its respective directors, officers, shareholders, employees, agents and representatives against all claims for injury to, or death of, persons or for damage to property arising as a result of any act or omission committed by Buyer or its employees, agents, contractors or representatives in conducting Buyer's on-site inspections and environmental assessments of the Leases and Wells. This waiver, release and indemnity by Buyer shall survive termination of this Agreement.

3.4 Buyer's Agents.

To the extent that Buyer uses agents to conduct its due diligence activities, either in Seller's offices or on the Lands, Buyer agrees to (i) make such agents aware of the terms and conditions set forth in this Article 3 and the confidentiality provisions of Article 8, and (ii) ensure that such agents agree to be bound by the terms of this Article 3 and the confidentiality provisions of Article 8.

ARTICLE 4
TITLE MATTERS

4.1 Definitions

A. Defensible Title.

The term "Defensible Title" means such title to the Assets, that, subject to and except for Permitted Encumbrances: (i) entitles Seller to receive not less than the net revenue interest set forth on Exhibit B for each Well, Unit or undeveloped location listed on Exhibit B ("NRI"); (ii) obligates Seller to bear costs and expenses relating to the maintenance, development, operation and the production of Hydrocarbons from each Well, Unit or undeveloped location in an amount not greater than the working interest set forth in Exhibit B ("WI"); (iii) is not subject to reduction by virtue of the exercise by any third party of a reversionary interest, back‑in or similar right except as scheduled in Exhibit B; (iv) is free and clear of mortgages, encumbrances, liens, and delinquent taxes; (v) is free and clear of any surface use restrictions that would reduce the PUD value to $0; and (vi) defects or conditions that would create a material impairment of use or loss of interest in the affected Asset. Topography, directional drilling costs, permitting issues, (including federal, state, county and municipal) shall not be taken into account when calculating an undeveloped location value. If a formation in a Well or undeveloped location is not listed on Exhibit B, then the Allocated Value for such formation or undeveloped location is zero.

B. Permitted Encumbrances.

The term "Permitted Encumbrances" shall mean:

1. lessors' royalties, overriding royalties, net profits interests, production payments, reversionary interests and similar burdens (payable or in suspense) if the net cumulative effect of such burdens does not operate to reduce the represented NRI;

2. liens for Taxes, or assessments not yet due and delinquent;

3. all rights to consent by, required notices to, filings with, or other actions by federal, state, or local governmental bodies, in connection with the conveyance of the applicable Asset if the same are customarily obtained after such conveyance ("Routine Consents");

4. rights of reassignment upon the surrender or expiration of any Lease;

5. the terms and conditions of the Material Agreements to the extent such do not decrease the NRI for the affected Asset or increase the WI for such Asset without a corresponding proportionate increase in the NRI for such Asset;

6. easements, rights-of-way, servitudes, permits, surface leases and other rights with respect to surface operations, on, over or in respect of any of the Assets or any restriction on access thereto so long as the same do not materially interfere with the operation of the affected Asset as has been conducted in the past and do not materially affect the value thereof; and

7. materialmen's, mechanics', operators' or other similar liens arising in the ordinary course of business incidental to operation of the Assets if such liens and charges have not been filed pursuant to law and the time for filing such liens and charges has expired.

C. Title Defect.

The term "Title Defect" means any lien, encumbrance, claim, defect in or objection to real property title, excluding Permitted Encumbrances, that alone or in combination with other defects renders the Seller's title to the Asset less than Defensible Title. Notwithstanding the foregoing, the following shall not be considered Title Defects:

1. defects in the early chain of title, consisting of the failure to recite marital status in a document or omissions of successors of heirship or estate proceedings that would generally be waived by a prudent purchaser of oil and gas properties in the area, unless Buyer provides reasonable written evidence that such failure or omission has resulted in another party claiming title to the relevant Asset;

2. defects based on a lack of information in Seller's files;

3. defects arising out of lack of survey;

4. defects arising out of lack of corporate or other entity authorization that would generally be waived by a prudent purchaser of oil and gas properties in the area unless Buyer provides affirmative written evidence that the action was not authorized and results in another party claiming title to the Asset; and

5. defects that have been cured by possession under applicable statutes of limitation for adverse possession or for prescription.

D. Title Defect Value.

"Title Defect Value" means the amount by which the Allocated Value of an Asset has been reduced by a Title Defect. In determining the Title Defect Value, the Parties intend to include only that portion of the Asset affected by the defect. The Title Defect Value may not exceed the Allocated Value of the Asset and shall be determined by the Parties in good faith taking into account all relevant factors, including without limitation, the following:

1. If the Title Defect is a lien or encumbrance on the Asset created by, through or under Seller, Seller shall have the lien or encumbrance unconditionally released as a condition precedent to Closing and, consequently, there shall be no Title Defect Value associated with such lien or encumbrance.

2. If the Title Defect is an actual reduction in NRI or any other matter that does not fall within the matters described in Subsection 4.1.D.1., then the Buyer will rerun its economic valuation calculation that resulted in the Allocated Value for the affected portion of the Assets using the same economic and engineering criteria except as changed to accommodate the Title Defect to calculate the impact on the Allocated Value for the affected Asset. This revised calculation of the Allocated Value will be presented to Seller and Buyer and Seller will act in good faith to reach mutual agreement as to the diminution effect of this Title Defect and thus the Title Defect Value.

4.2 Purchase Price Adjustments for Title Matters.

A. Notices of Title Defects.

Buyer shall give Seller a written "Title Defects Notice" as soon as possible but no later than 5:00 p.m. Mountain Time on December 12, 2006 (the "Title Defect Date"). To be effective, each Title Defect Notice must be in writing and must satisfy the following conditions precedent: (i) name the affected Asset; (ii) describe each Title Defect in reasonable detail; (iii) describe the basis for each Title Defect; (iv) attach Supporting Documentation; (v) state the Allocated Value of the affected Asset; (vi) state Buyer's good faith estimate of the Title Defect Value; (vii) set forth the computations, upon which Buyer's estimate is based; and (viii) each Title Defect must be equal to or greater than $50,000.00 in value. For the purposes of this Section, "Supporting Documentation" for a particular Title Defect means if the basis is derived from any document, a copy of such document (or pertinent part thereof) or if the basis is derived from any gap in Seller's chain of title, the documents preceding and following the gap, or in any case other reasonable written documentation.

B. Downward Defect Adjustments.

1. If an Asset is affected by a Title Defect, the Purchase Price will be reduced as set forth below and in Section 4.1.D.2, unless: (i) Seller elects to cure the Title Defect prior to Closing to Buyer's reasonable satisfaction; (ii) Buyer agrees to waive the relevant Title Defect; (iii) Seller elects on or before Closing to cure such Title Defect no later than 90 days after Closing; (iv) Seller, with Buyer's consent, which Buyer may withhold in its sole discretion, elects on or before Closing to indemnify Buyer against any Loss (as defined below) attributable to the relevant Title Defect; or (v) Seller elects on or before Closing to exclude the affected portion of the Asset from the Transaction and reduce the Purchase Price accordingly.

2. The Purchase Price shall be adjusted downward for Title Defects only if and to the extent that the aggregate value of all Title Defects exceeds $250,000.00 (the "Title Defect Deductible"). If the aggregate value of the Title Defects does not exceed the Title Defect Deductible, there shall be no adjustment to the Purchase Price, and, except for matters that are subject to the special warranty of title contained in the Assignment to be delivered at Closing, Buyer will be deemed to have (i) accepted title to the Assets "AS IS WHERE IS," and (ii) waived its right to assert any objection to real property title to the Assets.

3. If Seller elects to cure the relevant Title Defect post-Closing, the Parties shall proceed as provided in this Section. If the Title Defect Value is equal to the Allocated Value of the affected Asset, Seller shall deposit the assignment of the Asset affected by the Title Defect (the "Affected Asset") in the Escrow Account and Buyer shall deposit the Allocated Value of the Affected Asset in the Escrow Account. If the Title Defect Value is less than the Allocated Value of the affected Asset, Seller shall assign the Asset to Buyer on the Closing Date, Buyer shall deposit the Title Defect Value in the Escrow Account, and the Purchase Price payable by Buyer to Seller on the Closing Date shall be adjusted downward by the Title Defect Value deposited by Buyer into the Escrow Account. If Seller cures the relevant Title Defect to Buyer's reasonable satisfaction, the Parties shall instruct the Escrow Agent (i) to deliver to Seller the Allocated Value of the Affected Asset, adjusted as set forth in Section 2.4 and, if relevant at that time, Section 13.1, or the Title Defect Value, as applicable, and (ii) to deliver to Buyer the remainder of the Allocated Value of the Affected Asset (if any) and the assignment of the affected Asset if the assignment has been deposited into the Excrow Account. If Seller does not cure the relevant Title Defect to Buyer's reasonable satisfaction, the Purchase Price shall be adjusted as set forth in Section 4.2.B.2., and the Parties shall instruct the Escrow Agent to deliver the Allocated Value or the Defect Value, as applicable, of the Affected Asset to Buyer. If Seller does not cure a Title Defect to Buyer's reasonable satisfaction and the Title Defect Value is equal to the Allocated Value of the affected Asset, the Parties will instruct the Escrow Agent to return the assignmnent of the affected Asset to Seller. Interest accruing on such amount shall be distributed to each of the Parties in proportion to the amount of the Allocated Value distributed to such Party.

C. Upward Defect Adjustments.

If Buyer or Seller discover additional interests in the Leases, Wells or undeveloped locations that are listed in Exhibit A and Exhibit B, including any interest that entitles Seller to receive more than the NRI set forth in Exhibit B or obligates Seller to bear costs and expenses in an amount less than the WI set forth in Exhibit B without a corresponding reduction in Seller's NRI, the discovering party shall promptly notify the other Party of such interest (the "Additional Interest"). The party who discovers Additional Interest shall give the other party written notice of the Additional Interest as soon as possible, but in no event later than the Title Defect Date. This notice shall be in writing and shall include (i) a description of each Additional Interest, (ii) the basis for each Additional Interest, and supporting documentation with respect thereto, (iii) the Allocated Value of the Lease, Well or undeveloped location affected by the Additional Interest, and (iv) the value of the Additional Interest or the amount by which the notifying party believes the Allocated Value of the Lease, Well or undeveloped location has been increased by the Additional Interest and the computations upon which such party's belief is based. The value of the Additional Interest shall be determined by the parties in good faith taking into account all relevant factors.

4.3 Title Matters Dispute Resolution.

The Parties agree to resolve disputes concerning title matters pursuant to the terms of this Section. The Parties agree to submit all disputes concerning title matters regarding (i) the existence and scope of a Title Defect, (ii) the Title Defect Value of that portion of the Asset affected by a Title Defect or (iii) the adequacy of Seller's Title Defect curative materials, to binding arbitration in Denver, Colorado, such arbitration to be conducted as follows. The arbitration proceeding shall be submitted to a three-person panel of neutral arbitrators consisting of three attorneys licensed in Colorado, each with at least 15 years experience in preparing oil and gas title opinions (the Title Arbitration Panel"). The arbitration shall be governed by Colorado law and shall be held in Denver, Colorado. The membership of the Title Arbitration Panel shall consist of one attorney picked by each side, and the two arbitrators so selected picking the third. The Parties shall submit written materials to the Title Arbitration Panel within 10 days of the selection of the third arbitrator explaining their position regarding the title dispute. The Title Arbitration Panel shall conduct a hearing, if necessary, no later than 30 days after the selection of the third arbitrator, and the Title Arbitration Panel shall render a written decision within 15 days of the hearing or, if no hearing is conducted, not later than 45 days after the third arbitrator is selected. At the hearing, the Parties shall present such evidence and witnesses as they may choose, with or without counsel. Adherence to formal rules of evidence shall not be required but the Title Arbitration Panel shall consider any evidence and testimony that they determine to be relevant, in accordance with procedures that they determine to be appropriate. The final decision shall be binding on the Parties, final and non-appealable, and may be filed in a court of competent jurisdiction and may be enforced by any Party as a final judgment of such court. Each Party shall bear its own costs and expenses of the arbitration, provided, however, that the costs of employing the Title Arbitration Panel shall be borne 50% by the Seller and 50% by the Buyer. Disputes regarding title matters in excess of $1,000,000.00 shall be resolved pursuant to the arbitration procedure set forth in Section 14.7.

4.4 Casualty Loss.

After the Effective Time and prior to Closing, if a portion of the Assets is destroyed by fire or other casualty, or is taken or threatened to be taken in condemnation or under the right of eminent domain, (with such event being a "Casualty Loss"), Buyer shall purchase the Asset at Closing for the Allocated Value of the Asset reduced by the estimated cost to repair or replace such Asset (with equipment of similar utility). At its sole option, Seller may elect to cure such Casualty Loss. If Seller elects to cure such Casualty Loss, Seller may replace any personal property that is the subject of a Casualty Loss with equipment of similar grade and utility and Seller shall be entitled to keep all associated insurance proceeds, if any. If Seller cures the Casualty Loss to Buyer's reasonable satisfaction, Buyer shall purchase the affected Asset at Closing for the Allocated Value thereof without any Purchase Price adjustment for such Casualty Loss. In no event shall the watering out of a well, casing collapse, or breakage of equipment constitute a Casualty Loss.

4.5 Preferential Rights and Required Consents.

To Seller's knowledge, other than Routine Consents and those shown on Exhibit M, there are no preferential rights to purchase the Assets ("Preferential Rights") and no consents to the assignment thereof that are required to be obtained in connection with the consummation of the Transaction ("Required Consents"). If there are Preferential Rights or Required Consents, the provisions of this Section shall apply. If either Party discovers Assets affected by Preferential Rights or Required Consents, Seller shall use its best efforts to give the notices required in connection with the Preferential Rights in sufficient time prior to Closing to permit the lapse of the period of time in which to exercise such Preferential Rights prior to Closing and shall use its best efforts to obtain such Consents prior to Closing.

A. Required Consents.

If a Required Consent has not been obtained as of the Closing, then (i) the portion of the Assets for which such Required Consent has not been obtained shall not be conveyed at the Closing, (ii) the Allocated Value for that Asset shall not be paid to Seller, and (iii) Seller shall use its reasonable efforts to obtain such Required Consent as promptly as possible following Closing. If a Required Consent has been obtained as of the Final Settlement Date, Seller shall convey the affected Asset to Buyer effective as of the Effective Time and Buyer shall pay Seller the Allocated Value of the affected Asset, reduced by the amount of any net proceeds from the affected Asset attributable to the period of time after the Effective Time with Seller retaining such net proceeds attributable to the period of time after the Effective Time until the affected Asset is assigned, and with Seller bearing all attendant costs in connection therewith, including Property Expenses, royalties and overriding royalties, lease rental and maintenance costs and leasehold payments for the affected Asset accruing during this period of time. If such Required Consent has not been obtained as of the Settlement Date, the affected Asset shall be deemed to be an Excluded Asset and Seller shall retain such Asset and the Purchase Price shall be deemed to be reduced by an amount equal to the Allocated Value of the particular Asset (with such adjustment being an "Exclusion Adjustment"). Buyer shall reasonably cooperate with Seller in obtaining any Required Consent including providing assurances of reasonable financial conditions, but Buyer shall not be required to expend funds or make any other type of financial commitments a condition of obtaining such consent.

B. Preferential Rights.

1. If any Preferential Right affecting any portion of the Assets is exercised and consummated prior to the Closing Date, that portion of the Assets affected by such Preferential Right shall be deemed to be Excluded Assets and the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of such affected Assets without the requirement for Buyer to give notice (with such adjustment being an "Exclusion Adjustment").

2. If by Closing, the time frame for the exercise of such Preferential Rights has not expired and Seller has not received notice of an intent not to exercise or a waiver of the Preferential Right, that portion of the Assets affected by such Preferential Right shall be included in the Assets and assigned to Buyer at Closing. If such Preferential Right is exercised, the provisions of Section 4.5.B.3 shall apply.

3. If the affected Asset has been conveyed to Buyer at Closing, and a Preferential Right affecting the Asset is consummated after Closing, Buyer agrees to convey such affected Asset to the party exercising such Preferential Right on the same terms and conditions under which Seller conveyed such Assets to Buyer and retain all amounts paid by the party exercising such Preferential Right. In the event of such exercise, Buyer shall prepare, execute and deliver a form of conveyance of such Asset to such exercising party, such conveyance to be in form and substance as provided in this Agreement, and Seller agrees to hold harmless and indemnify Buyer from any and all liabilities and obligations associated with such conveyed Asset.

C. Exclusive Remedy.

The remedies set forth in this Section 4.5 are the exclusive remedies under this Agreement for Preferential Rights and Required Consents.

ARTICLE 5
ENVIRONMENTAL MATTERS

The provisions of this Article apply only to the environmental matters associated with the Assets as the result of oil and gas operations on the Lands.

5.1 Definitions.

For the purposes of the Agreement, the following terms shall have the following meanings:

"Environmental Consultant" means a qualified environmental consultant engaged by Buyer, or a qualified employee of Buyer assigned by Buyer, to investigate and assess the environmental condition of the Assets; provided, however, that the duties of the Environmental Consultant provided herein shall, if exercised by a qualified employee of Buyer, be performed in good faith.

"Environmental Defect" means (a) a condition in, on or under an Asset (including, without limitation, air, land, soil, surface and subsurface strata, surface water and ground water or sediments) that causes an Asset to be in violation of an Environmental Law; and (b) Seller has timely received a Valid Environmental Defect Notice for the Environmental Defect. It is understood and agreed that matters of an essentially similar nature such as, but not limited to, oil spills, chemical barrels or equipment containing NORM found at a single site shall be deemed a single incident or condition. The Parties agree that each Environmental Defect will be addressed as a single incident or condition, and that Environmental Defects will not be aggregated on a per condition basis or otherwise (i.e., chemical barrels found at all of the Well sites shall not be aggregated, but instead, shall be evaluated on a site by site basis).

"Environmental Defect Deductible" means $250,000.00.

"Environmental Defect Notice" means a written notice given by Buyer to Seller alleging an Environmental Defect. To be effective, each Environmental Defect Notice must be in writing and must satisfy the following conditions precedent: (i) name the affected Asset, (ii) describe the condition that causes the Environmental Defect, (iii) provide reasonable factual substantiation for the Environmental Defect, and (iv) state the estimated cost to remediate as calculated by the Environmental Consultant. To be valid, all Environmental Defect Notices must be received by Seller on or before December 12, 2006 at 5:00 p.m. Mountain Time. For the purpose of the preceding sentence, "factual substantiation for the Environmental Defect" shall mean reports prepared by, or the basis of tests performed by the Environmental Consultant.

"Environmental Law" means any law, statute, rule, regulation, code, ordinance or order issued by any federal, state, or local governmental entity regulating or imposing liability or standards of conduct concerning protection of the environment or human health and safety or the release or disposal of waste or hazardous materials.

"Remediation" means actions taken to correct an Environmental Defect or otherwise required to remediate in compliance with applicable Environmental Law, as recommended in writing by the Environmental Consultant.

5.2 Environmental Representations.

With respect to the Assets operated by Seller, to Seller's knowledge, Seller has been in material compliance with and has not been and is not in any material respect in violation of or liable under, any Environmental Law. With respect to the Assets, Seller has not received any actual or threatened order, notice or other communication of any actual or potential violation or failure to comply with any Environmental Law.

5.3 Environmental Liabilities and Obligations

A. Retained Environmental Liabilities.

Upon Closing, if and to the extent the aggregate of all Environmental Defects exceeds the Environmental Defect Deductible, and subject to subsection 5.3 C below, Seller shall retain and pay, perform, fulfill and discharge all claims, cost, expenses, liabilities and obligations accruing or relating to and release Buyer from all Losses attributable to and relating to Environmental Defects for which Seller receives a timely Environmental Defect Notice (the "Retained Environmental Liabilities"). Timely receipt of an Environmental Defect Notice, verification of the cost to remediate by the Environmental Consultant, and the aggregate of all Environmental Defects exceeding the Environmental Defect Deductible, are conditions precedent to Seller's obligation to retain liability for Retained Environmental Liabilities.

B. Assumed Environmental Liabilities.

If the aggregate of all Environmental Defects does not exceed the Environmental Defect Deductible, upon Closing, subject to the limitations set forth in Article 14, Buyer shall assume and pay, perform, fulfill and discharge and release Seller from all Losses relating to environmental conditions in, on or under the Assets attributable to the period of time before and after the Effective Time, including without limitation any and all liability for (i) ground water contamination, (ii) Naturally Occurring Radioactive Materials, (iii) man-made material fibers, or (iv) the obligation to plug and abandon all of the wells located on the Lands and reclamation of existing well sites on the Lands (collectively, the "Assumed Environmental Liabilities").

C. Remedies.

If the aggregate values of all Environmental Defects exceed the Environmental Defect Deductible, with respect to Environmental Defects, Seller shall elect one of the following options: (i) remediate the condition on the affected Assets comprising the specified Environmental Defect(s) as promptly as practicable (and retain its obligation to indemnify and defend Buyer from any Losses relating to such Environmental Defects), such remediation to be consistent with Environmental Laws; or (ii) pay Buyer, no later than 10 days following the delivery of the applicable Environmental Defect Notice(s), Buyer's estimate of the Environmental Defect Value, in which event Buyer shall release Seller from any further Retained Environmental Liability relating to the Environmental Defects so satisfied.

5.4 Contested Environmental Defects.

If Seller contests the existence of an Environmental Defect or the Environmental Defect Value, Seller shall notify Buyer in writing on or before December 15, 2006, at 5:00 p.m. Mountain Time ("Rejection Notice"). The Rejection Notice shall state with reasonable specificity the basis of the rejection of the Environmental Defect or the Environmental Defect Value.

If the Parties cannot agree on either options (i) or (ii) in the preceding sentence, the Environmental Defect and/or the Environmental Defect Value subject to the Rejection Notice shall be resolved in accordance with the arbitration procedures set forth in Section 14.7. If Seller fails to timely deliver a Rejection Notice, Seller shall be deemed to have accepted the validity of the Environmental Defect and Buyer's estimate of the Environmental Defect Value, and shall be deemed to have waived its own option to contest the Environmental Defect pursuant to this Section.

5.5 Exclusive Remedies.

For purposes hereof, "Final Decision" means a decision, order, judgment or decree of an arbitrator or court of competent jurisdiction accompanied by an opinion of Buyer's or Seller's counsel, as appropriate, which decision, order, judgment or decree has been finally affirmed on appeal or by lapse of time or otherwise is no longer subject to appeal.

6.                  Investment of Escrow Funds. The Escrow Funds shall be credited by Escrow Agent and recorded in an escrow account. Escrow Agent shall be permitted, and is hereby authorized, to deposit, transfer, hold and invest all funds received under this Escrow Agreement, including principal and interest, in the Wells Fargo Advantage 100% Treasury Money Market Fund ("Wells Fargo Advantage Funds") during the period of this escrow. Any interest received by Escrow Agent with respect to the Escrow Funds, including reinvested interest, shall become part of the Escrow Funds and shall be disbursed according to Section 4 of this Agreement. The parties agree that, for tax reporting purposes, all interest or other taxable income earned on the Escrow Funds in any tax year shall be taxable to the recipient of such income.

The parties hereto shall, within thirty (30) days after the date hereof, provide Escrow Agent with certified tax identification numbers by furnishing appropriate IRS forms W-9 or W-8 and other forms and documents that Escrow Agent may reasonably request. The parties hereto understand that if such tax reporting documentation is not so certified to Escrow Agent, Escrow Agent may be required by the Internal Revenue Code of 1986, as amended, to withhold a portion of any interest or other income earned on the Escrow Funds pursuant to this Escrow Agreement.

The Escrow Agent shall be entitled to sell or redeem any such investments as necessary to make any payments or distributions required under this Escrow Agreement. The Escrow Agent shall have no responsibility or liability for any loss which may result from any investment made pursuant to the instructions of Buyer or Seller, or for any loss resulting from the sale of such investment pursuant to the instructions of Buyer or Seller. The parties acknowledge that the Escrow Agent is not providing investment supervision, recommendations, or advice.

Investments in the Wells Fargo Advantage Funds are not obligations of, or endorsed or guaranteed by, the Escrow Agent or its affiliates and are not insured by the Federal Deposit Insurance Corporation. The Escrow Agent and its affiliates provide various services for the Wells Fargo Advantage Funds and are paid fees for such services. Proceeds of the sale of investments will be delivered on the business day on which the appropriate instructions are received by the Escrow Agent if received prior to the deadline for same day sale of such permitted investments. If such instructions are received after the applicable deadline, proceeds will be delivered on the next business day.

Investments will be made promptly following the availability of such funds to the Escrow Agent taking into consideration the regulations and requirements (including investment cut-off times) of the Federal Reserve wire system, any investment provider, and the Escrow Agent.

To the extent that Escrow Agent becomes liable for the payment of any taxes in respect of income derived from the investment of funds held or payments made hereunder, Escrow Agent shall satisfy such liability to the extent possible from the Escrow Funds. The parties agree to indemnify and hold Escrow Agent harmless from and against any taxes, additions for late payment, interest, penalties and other expenses that may be assessed against Escrow Agent on or with respect to any payment or other activities under this Escrow Agreement unless any such tax, addition for late payment, interest, penalties and other expenses shall arise out of or be caused by the actions, or failure to act, of Escrow Agent.
