ARTICLE III

BUYER’S INSPECTION

3.1 Access to Records.

From and after the date of this Agreement until Closing, and subject to this Section 3.1, Seller will make the Records available to Buyer and Buyer’s authorized representatives for inspection and review at Seller’s offices where the respective Records are maintained, during normal business hours for the purpose of permitting 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, additional information in the possession of a Third Party as Buyer may reasonably desire.

3.2 Access to Properties.

From and after the date of this Agreement until Closing, Seller will, upon reasonable advance notice, allow Buyer and Buyer’s authorized representatives to conduct, at Buyer’s sole risk and expense, on-site inspections and environmental assessments of the Lands, Wells and lands owned by Laramie Land during reasonable business hours. In connection with any such on-site inspections, Buyer agrees not to interfere with the normal operation of the Properties and agrees to comply with all requirements of the operator. Buyer shall provide to Seller any plan for such an environmental assessment prior to commencement of field work. If Buyer prepares its own environmental assessment of any Property, Buyer will furnish copies thereof to Seller. In connection with granting such access, Buyer represents that it is adequately insured and, except to the extent caused by Seller’s gross negligence or willful misconduct, Buyer waives, releases and agrees to indemnify, defend, save and hold harmless the Seller Indemnified Parties against all claims for injury to, or death of, Persons or for damage to property arising in any way from the access afforded to Buyer hereunder or the activities of Buyer. This waiver, release and indemnity by Buyer shall survive the termination of this Agreement.

ARTICLE IV

TITLE MATTERS

4.1 Defensible Title.

(a) Defensible Title – Definitions. The term “Defensible Title” means, as to each Well or Well Location described on Exhibit B, such title held by Seller that: (i) for each such Well or Well Location, entitles Seller (and after Closing will entitle Buyer) to receive not less than the net revenue interest (the “NRI”) set forth in Exhibit B for such Well or Well Location, without reduction, suspension or termination (except as set forth in Exhibit B); (ii) obligates Seller (and after Closing will obligate Buyer) to bear costs and expenses relating to the

maintenance, development, operation and the production of Hydrocarbons from the Well or Well Location in an amount not greater than the corresponding working interest (the “WI”) set forth in Exhibit B without a corresponding increase in the NRI (except as set forth in Exhibit B); (iii) is reflected by appropriate documentation properly filed in the official records of Mesa County or Garfield County, Colorado, and of the United States Bureau of Land Management, as applicable; (iv) is not adversely affected by any failure of Seller or others to have obtained any Permit or other regulatory action from any Governmental Authority necessary or desirable for the ownership or operation thereof in accordance with historical practice or that are necessary to carry out the drilling of the Well Locations described in Schedule 8.1(a)(ii); and (v) subject to and except for the Permitted Encumbrances, is free and clear of liens, security interests, title defects and encumbrances of any kind or character. The term “Defensible Title” means, as to each Other Asset, such title held by Seller that: (i) is good and marketable, subject to and except only for the Permitted Encumbrances; and (ii) is not adversely affected by any failure of Seller or others to have obtained any Permit or other regulatory action from any Governmental Authority necessary or desirable for the ownership or operation thereof in accordance with historical practice or that are necessary to carry out the drilling of the Well Locations described in Schedule 8.1(a)(ii).

(b) Allocated Value. If a Well, Well Location or any Other Asset has not been given an Allocated Value by Buyer, or if the Allocated Value (prior to any adjustments hereunder) of such Well, Well Location or Other Asset is $20,000 or less, Seller shall be deemed to have Defensible Title to such Well, Well Location or Other Asset.

4.2 Purchase Price Adjustments for Defective Interests.

(a) Defective Interest. “Defective Interest” means a Well, Well Location or Other Asset affected by a Title Defect that reduces the Allocated Value of the affected Well, Well Location or Other Asset by more than $20,000 (the “Individual Title Defect Threshold”). For purposes hereof, a “Title Defect” means any lien, encumbrance, adverse claim, encroachment, irregularity, defect in or objection to title, excluding Permitted Encumbrances, that alone or in combination with other defects renders Seller’s title to a Well, Well Location or Other Asset less than Defensible Title.

(b) Notice of Defective Interest. Buyer shall give Seller written notice (a “Notice of Defective Interest”) as soon as Title Defects are discovered, and in any event no later than the Closing Date (the “Notice Deadline”). A Notice of Defective Interest shall include all of the following: (i) a description of each Defective Interest; (ii) the basis for each Defective Interest, and, if the basis is derived from any document, a copy of such document (or pertinent part thereof) shall be attached, or if the basis is derived from any gap in the chain of title, the documents preceding and following the gap shall be attached; (iii) the Allocated Value of such affected Well, Well Location or Other Asset; and (iv) Buyer’s good faith estimate of the Defect Value and the computations upon which Buyer’s estimate is based. To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use reasonable efforts to give Seller, on or before the end of each calendar week prior to the Notice Deadline, a Notice of Defective Interest covering all Title Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Notice Deadline.

(i) Subject to Sections 4.2(a) and (b), if a Well, Well Location or Other Asset is a Defective Interest, the Purchase Price will be reduced under Section 2.7(b)(iv) by the corresponding Defect Value (which reduction is called a “Defect Adjustment”) unless (A) the basis for treating such Well, Well Location or Other Asset as a Defective Interest has been removed by Seller at its sole cost and expense to the reasonable satisfaction of Buyer prior to Closing, (B) Buyer agrees to waive the relevant Title Defect, (C) Seller elects not later than two business days prior to Closing to cure such Title Defect no later than 90 days after Closing, or (D) Seller elects to retain the entirety of the Well, Well Location or Other Asset that is subject to such Title Defect and treat it as an Excluded Asset, in which case the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Well, Well Location or Other Asset. Any Purchase Price reduction under clause (D) shall also constitute a Defect Adjustment for purposes of this Agreement. If Seller and Buyer elect not to pursue any of the options in clauses (A), (B), or (C) in the previous sentence with respect to any Defective Interests, the Purchase Price shall be reduced pursuant to Section 2.7(b)(iv).

(ii) In order to provide security for Title Defects to be cured after Closing, for Environmental Defects resolved under Section 5.5, and for indemnity claims under Section 14.1, at Closing (i) the Shares and (ii) $12,500,000 of the Purchase Price shall be deposited by Buyer into the Escrow Account (in case of the Shares, by delivery of the certificate representing the Shares accompanied by a properly completed undated stock power, duly executed in blank by the record holder and in the case of the amount specified in clause (ii), by wire transfer).

(A) If any Title Defect that Seller has elected to cure is cured to the reasonable satisfaction of Buyer on or before 90 days after Closing, Buyer shall so notify Seller within 15 days after receipt of such curative materials. Within five days after Buyer has notified Seller that such Title Defect has been cured to its reasonable satisfaction, the parties shall instruct the Escrow Agent to distribute to Seller out of the Escrow Account the Defect Value for such Title Defect. If Buyer disputes the adequacy of Seller’s curative material with respect to, or that Seller has adequately cured, any Title Defect, Buyer shall so notify Seller within 15 days after receipt of such curative materials.

(B) If Seller provides no curative materials to cure a Title Defect within the 90-day time period, subject to Seller’s rights under Section 4.2(c)(ii)(C) below, Buyer may elect to treat the affected Wells, Well Locations or Other Assets as Excluded Assets, in which case Buyer will cause the Excluded Asset to be assigned to Seller or Seller’s designee effective as of the Effective Time free of all liens, encumbrances and defects arising by, through or under Buyer. Upon such election by Buyer, Buyer shall have the option to either (1) receive the Allocated Value of the Excluded Asset as a credit to Buyer in the Final Settlement Statement prepared pursuant to Section 13.1, or (2) have the parties instruct the Escrow Agent to distribute to Buyer, promptly after Buyer’s election to treat the affected Property as an Excluded Asset, the Defect Value with respect to such Title Defect.

(C) If Buyer disputes the adequacy of Seller’s curative materials or that a Title Defect has been cured by Seller, or if Seller disputes the Defect Value

asserted by Buyer for a Title Defect covered by Section 4.2(c)(ii)(B), the issue of the adequacy of the curative materials, the fact of the cure or the amount of the Defect Value will be deemed submitted for resolution under Section 4.4. The actual Defect Value for the Title Defect as determined under Section 4.4 shall be distributed to Buyer on the Final Settlement Date (or later determination of the Defect Value).

(iii) Notwithstanding anything to the contrary in this Section 4.2, (A) in no event shall there be any Defect Adjustment or other remedies provided by Seller for any Title Defect for which the Defect Value does not exceed the Individual Title Defect Threshold, and (B) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Defective Interest, unless the sum of the Defect Adjustments for all Defective Interests and Environmental Defects, in the aggregate, excluding any Title Defects cured by Seller, exceeds one and one-half percent (1.5%) of the Purchase Price (the “Aggregate Defect Deductible”), after which point Buyer shall be entitled to adjustments to the Purchase Price only with respect to aggregate Defect Adjustments and Environmental Defects in excess of the Aggregate Defect Deductible.

(d) Defect Value. The amount by which the Allocated Value of a Defective Interest has been reduced by a Title Defect (the “Defect Value”) shall be determined in accordance with this Section 4.2(d). In determining which portion of a Property is a Defective Interest pursuant to this Section 4.2(d), it is the intent of the parties to include, to the extent possible, only that portion of the Property adversely affected by the defect as a Defective Interest. The Defect Value may not exceed the Allocated Value of the Property, and shall be determined by the parties in good faith taking into account all relevant factors, including, without limitation, the following:

(i) the Allocated Value of the affected Property;

(ii) in the case of Wells or Well Locations, the potential for, or actual reduction in, the NRI of the Defective Interest, or the potential for, or actual increase in, the WI to the extent such increase is not accompanied by a corresponding increase in the NRI of the Defective Interest;

(iii) if the Title Defect represents only a possibility of title failure, the probability that such failure will occur;

(iv) the legal effect of the Title Defect; and

(v) if the Title Defect is a lien or encumbrance on the Property, the cost of removing such lien or encumbrance.

(e) Waiver. Subject to Seller’s special warranty of title to be contained in the Assignment and Bill of Sale referred to in Section 12.3(a), Buyer shall be deemed to have conclusively waived all Title Defects (i) that do not qualify as Defective Interests, or (ii) that are not disclosed to Seller in a Notice of Defective Interests prior to the Notice Deadline. Any Title Defect waived shall be deemed a Permitted Encumbrance.

4.3 Interest Additions.

Promptly on discovery and in any event no later than the Notice Deadline, Seller may notify Buyer in writing of any interest that entitles a Seller to receive more than the NRI set forth in Exhibit B hereto with respect to a Well or Well Location listed thereon, to the extent the same does not cause a greater than proportionate increase in Seller’s WI therein above that shown on Exhibit B, or obligates Seller to bear costs and expenses in an amount less than the WI set forth in Exhibit B hereto, to the extent the same causes a decrease in Seller’s WI that is proportionately greater than the decrease in Seller’s NRI therein below that shown on Exhibit B (collectively, “Interest Additions”). Any notice of possible Interest Additions must include (a) a description of each Interest Addition, (b) the basis for each Interest Addition, (c) the Allocated Value of the Well or Well Location affected by the Interest Addition, and (d) the value of the Interest Addition or the amount by which Seller believes the Allocated Value of the Well or Well Location has been increased by the Interest Addition (“Value of Interest Addition”) and the computations upon which Seller’s belief is based. The Value of the Interest Addition shall be determined by the parties in good faith taking into account all relevant factors including those set forth in Section 4.2(d), and the Purchase Price will be increased in accordance with Section 2.7(a)(vi) by the amount by which the aggregate of all Value of Interest Additions exceeds one and one-half percent (1.5%) of the Purchase Price (an “Interest Addition Adjustment”). If Buyer disputes the existence of an Interest Addition or the Value of an Interest Addition, the issue will be deemed submitted for resolution under Section 4.4. Seller shall be deemed to have conclusively waived all Interest Addition Adjustments that are not disclosed to Buyer in writing by the Notice Deadline.

4.4 Title Dispute Resolution.

(a) The parties agree to resolve disputes concerning the following matters pursuant to this Section 4.4: (i) the existence and scope of a Title Defect, (ii) the Defect Value of that portion of the Properties affected by a Title Defect, (iii) the adequacy of Seller’s Title Defect curative materials submitted pursuant to Section 4.2(c) or of the cure of a Title Defect, and (iv) the existence or Value of an Interest Addition (collectively, the “Disputed Title Matters”).

(b) The parties agree to attempt to initially resolve all Disputed Title Matters through good faith negotiations. If the parties cannot resolve any such Disputed Title Matters on or before the Closing, then the Disputed Title Matters will be finally determined by an independent arbitrator mutually acceptable to the parties, who shall be a title attorney with at least 10 years experience in Colorado oil and gas titles or, if no such arbitrator is mutually acceptable and selected by the parties within 10 days after Closing, then as selected by the American Arbitration Association (in either event, the “Title Arbitrator”). The arbitration proceeding shall be held in Denver, Colorado and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association to the extent such rules do not conflict with the terms of this Section 4.4. The Title Arbitrator’s determination of the dispute shall be made within 20 days after submission of the matters in dispute, and shall be final and binding upon both parties, without right of appeal. In making his determination, the Title Arbitrator shall take into account the factors set forth in Sections 4.1 through 4.3. Notwithstanding the foregoing, for Disputed Title Matters arising with regard to Title Defects that Seller elects to cure after Closing, the Title Arbitrator shall be selected by the parties not

later than 100 days after Closing, and the Title Arbitrator’s determination of the dispute shall be made within 20 days after submission of the matters in dispute. The costs incurred in employing the Title Arbitrator shall be borne 50% by Seller and 50% by Buyer. After the Title Arbitrator makes a determination as to any Disputed Title Matters, the Title Arbitrator shall instruct the Escrow Agent to pay to Seller or Buyer the appropriate funds from the Escrow Account.

4.5 Casualty Loss and Condemnation.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the depreciation of personal property due to ordinary wear and tear, in each case, with respect to the Properties.

(b) If, after the date of this Agreement but prior to the Closing Date, any portion of the Properties is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain, and the Loss as a result of such individual casualty or taking exceeds ten percent (10%) of the Purchase Price based on the Allocated Value of the affected Assets, Buyer shall nevertheless be required to close and Seller shall elect by written notice to Buyer prior to Closing either (i) to cause the Assets affected by such casualty or taking to be repaired or restored to at least its condition prior to such casualty or taking, at Seller’s sole cost, as promptly as reasonably practicable (which work may extend after the Closing Date), or (ii) to treat such casualty or taking as basis for a downward adjustment to the Purchase Price pursuant to Section 2.7(b) with respect to the affected Asset or Assets under Section 4.3. In each case, Seller shall retain all rights to insurance, condemnation awards and other claims against third parties with respect to the casualty or taking except to the extent the parties otherwise agree in writing.

(c) If, after the date of this Agreement but prior to the Closing Date, any portion of the Properties is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain, and the Loss to the Assets as a result of all such casualties or taking is 10 percent (10%) or less of the Purchase Price based on the Allocated Value of the affected Properties, Buyer shall nevertheless be required to close and Seller, at Closing, shall pay to Buyer (i) all sums paid to Seller by Third Parties by reason of such casualty or taking insofar as with respect to the Properties and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards, and other rights against Third Parties (excluding any Liabilities, other than insurance claims, of or against any Seller Indemnified Parties) arising out of such casualty or taking insofar as with respect to the Properties and (ii) an amount equal to any applicable deductible under Seller’s insurance policies covering such Loss; provided, however, that Seller shall reserve and retain (and Buyer shall assign to Seller) all rights, title, interests and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to the Closing in pursuing or asserting any such insurance claims or other rights against third parties or in defending or asserting rights in such condemnation or eminent domain action with respect to the Properties.

(d) If any action for condemnation or taking under right of eminent domain is pending or threatened with respect to any Property or portion thereof after the date of this

Agreement, but no taking of such Property or portion thereof occurs prior to the Closing Date, Buyer shall nevertheless be required to close and Seller, at Closing, shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in such condemnation or eminent domain action, including any future awards therein, insofar as they are attributable to the Properties threatened to be taken, except that Seller shall reserve and retain (and Buyer shall assign to Seller) all rights, titles, interests and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to the Closing in defending or asserting rights in such action with respect to the Properties.

ARTICLE V

ENVIRONMENTAL MATTERS

5.1 Assertions of Environmental Defects.

(a) Buyer must deliver claim notices to Seller meeting the requirements of this Section 5.1 (collectively the “Environmental Defect Notices” and individually an “Environmental Defect Notice”) not later than the Notice Deadline setting forth any matters which, in Buyer’s reasonable opinion, constitute Environmental Defects and which Buyer intends to assert as Environmental Defects pursuant to this Section 5.1. For purposes hereof, an “Environmental Defect” shall mean the existence as of the date of any such notice with respect to the Assets or the operation thereof of any environmental pollution, contamination, degradation, damage or injury as to which remedial or corrective action is presently required (or if known, would be presently required) under Environmental Laws or which, if left unremediated, would reasonably be likely to require future Remediation under Environmental Laws as in effect at the Closing Date.

(b) For all purposes of this Agreement (excluding Section 14.1(c)), Buyer shall be deemed to have conclusively waived any Environmental Defect which Buyer fails to properly assert as an Environmental Defect by an Environmental Defect Notice received by Seller on or before the Notice Deadline.

(c) Each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter constituting the alleged Environmental Defect, (ii) a description of each Well, Well Location or other portion of the Assets that Buyer believes in good faith is affected by the alleged Environmental Defect, (iii) Buyer’s assertion of the Allocated Value of the portion of the Properties or other portion of the Assets affected by the alleged Environmental Defect, (iv) supporting documents reasonably necessary for Seller to verify the existence of the alleged Environmental Defect, and (v) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Defect. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the Environmental Condition that gives rise to the asserted Environmental Defect and identify all assumptions used by the Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws. Seller shall have the right, but not the obligation, to cure any claimed Environmental Defect on or before Closing.

5.2 Remedies for Environmental Defects.

(a) Subject to Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, in the event that any Environmental Defect timely asserted by Buyer in accordance with Section 5.1 is not waived in writing by Buyer or cured by Seller on or before Closing, Seller shall, at its sole option, elect to:

(i) subject to the Individual Environmental Threshold and the Aggregate Defect Deductible, reduce the Purchase Price by the Remediation Amount;

(ii) assume responsibility for the Remediation of such Environmental Defect; or

(iii) retain the Well, Well Location or other portion of the Assets that is subject to such Environmental Defect and treat it as an Excluded Asset, in which case the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Well, Well Location or other portion of the Assets. If the portion of the Assets affected by the Environmental Defect is a field facility that is not located on a Well or Well Location, then for purposes of this clause (iii), in making the election provided in this clause (iii) with regard to such Environmental Defect, Seller shall retain all of the Wells or Well Locations that are or will be served by the affected facility.

If Seller elects the option set forth in clause (i) above, Buyer shall be deemed to have assumed responsibility for Remediation of such Environmental Defect and such Environmental Defect and all liabilities with respect thereto shall be deemed to constitute Assumed Obligations. If Seller elects the option set forth in clause (ii) above, Seller shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that Seller elects to undertake and Buyer shall grant Seller access to the affected Property after the Closing Date to implement and complete such Remediation to the extent and as long as necessary to conduct and complete such Remediation. Seller will be deemed to have adequately completed the Remediation required in the immediately preceding sentence (A) upon receipt of a certificate or approval from the applicable Governmental Authority that the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements or (B) upon receipt of a certificate from a mutually agreeable licensed professional engineer that the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements.

5.3 Exclusive Remedy.

Subject to Sections 5.4 and 14.1(c), Section 5.2 shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect.

5.4 Environmental Deductibles.

Notwithstanding anything to the contrary in this Article V, (a) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual

Environmental Defect for which the Remediation Amount does not exceed $50,000 per individual Well, Well Location or other portion of the Assets affected by such Environmental Defect (“Individual Environmental Threshold”); and (b) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Threshold unless the sum of (i) the Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold, in the aggregate, excluding any Environmental Defects cured by Seller, plus (ii) the sum of the Defect Adjustments for all Defective Interests exceeds the Aggregate Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price only with respect to aggregate Environmental Defects and Defect Adjustments in excess of the Aggregate Defect Deductible.

5.5 Environmental Dispute Resolution.

Seller and Buyer shall attempt to agree on all Environmental Defects and Remediation Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 5.5. There shall be a single arbitrator, who shall be an environmental attorney with at least ten years experience in environmental matters involving oil and gas producing properties in Colorado, as selected by mutual agreement of Buyer and Seller within 15 days after the Closing Date, and absent such agreement, by the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be held in Denver, Colorado and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 5.5. The Environmental Arbitrator’s determination shall be made within 20 days after submission of the matters in dispute and shall be final and binding upon both parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 5.5 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award the Buyer a greater Remediation Amount than the Remediation Amount claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either party and may not award damages, interest or penalties to either party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price in the Final Settlement Statement pursuant to Section 13.1, then within ten days after the Environmental Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Remediation Amount, and subject to Article V, the Environmental Arbitrator shall instruct the Escrow Agent to pay to Seller or Buyer the appropriate funds from the Escrow Account.

5.6 NORM, Wastes and Other Substances.

Buyer acknowledges that the Properties have been used for exploration, development, and production of oil and gas and that there may be petroleum, produced water, wastes, or other substances or materials located in, on or under the Properties or associated with the Properties. Equipment and sites included in the Properties may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The wells, materials, and equipment located on the Properties or included in the Properties may contain NORM and other wastes or Hazardous Substances. NORM containing material and/or other wastes or Hazardous Substances may have come in contact with various environmental media, including without limitation, water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation, or disposal of environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Properties.

Proc. 2000-37), in connection with effectuation of a like-kind exchange. However, Seller and Buyer acknowledge and agree that any assignment of this Agreement to a Qualified Intermediary or to a Qualified Exchange Accommodation Titleholder does not release either party from any of its liabilities and obligations under this Agreement. If requested to do so, each party agrees to cooperate with the other to attempt structure the transaction as a like-kind exchange; provided, however, that neither party shall be required to assume any additional liabilities or obligations in connection with such like-kind exchange.

ARTICLE IX

TAX MATTERS

9.1 Apportionment of Tax Liability.

All Taxes shall be prorated between Buyer and Seller as of the Effective Time for all taxable periods that include the Effective Time. Based on the best current information available as of Closing, the proration shall be made between the parties as an adjustment to the Purchase Price pursuant to Section 2.7(b)(iii), and shall be subject to adjustment in the Final Settlement Statement based on then-current information, which shall then constitute a final settlement of Taxes between the parties. Taxes based on or measured by production of Hydrocarbons or the value thereof shall be deemed attributable to the period when such Taxes are assessed (even if the same are based on production or other activities occurring in prior periods). Accordingly, after Closing, and subject to adjustment in the Final Settlement Statement, Buyer expressly assumes its proportionate share of all obligations and liabilities for all Taxes payable by Seller that are assessed after the Effective Time, regardless of whether such Taxes are attributable to the period of time before or after the Effective Time.

9.2 Tax Returns and Reports.

For the tax period in which the Effective Time occurs, Seller agrees to immediately forward to Buyer any tax returns and reports relating to the Assets received by Seller after Closing and provide Buyer with any information Seller has in its possession that is necessary for Buyer to file any required tax returns and reports relating to the Assets. Buyer agrees to file all

tax returns and reports applicable to the Assets and required to be filed after the Closing, pay all required Taxes payable with respect to the Assets for which Buyer is responsible under this Agreement, and indemnify Seller against liability for the payment of such Taxes and the filing of such tax returns or reports. This indemnity shall survive Closing.

POST-CLOSING OBLIGATIONS

13.1 Post-Closing Adjustments.

(a) Preparation and Payment of Final Purchase Price. As soon as practicable after the Closing, but in no event later than 90 days after Closing, Seller, with assistance from Buyer’s staff, will prepare and deliver to Buyer, in accordance with customary industry accounting practices, the final settlement statement (the “Final Settlement Statement”) setting forth (i) each adjustment or payment that was not finally determined as of the Closing and showing the calculation of such adjustment, and (ii) the resulting final purchase price for the

Assets equal to the Closing Amount adjusted by the amounts in the foregoing clause (i) (the “Final Purchase Price”). As soon as practicable after receipt of the Final Settlement Statement, but in no event later than on or before 30 days after receipt of Seller’s proposed Final Settlement Statement, Buyer shall deliver to Seller a written report containing any changes that Buyer proposes to make to the Final Settlement Statement. Buyer’s failure to deliver to Seller a written report detailing proposed changes to the Final Settlement Statement by that date shall be deemed an acceptance by Buyer of the Final Settlement Statement as submitted by Seller. The parties shall agree with respect to the changes proposed by Buyer, if any, no later than 45 days after receipt of Seller’s proposed Final Settlement Statement. The date upon which such agreement is reached or upon which the Final Purchase Price is established shall be referred to herein as the “Final Settlement Date.” If the Final Purchase Price is more than the Closing Amount, Buyer shall pay Seller the amount of such difference. If the Final Purchase Price is less than the Closing Amount, Seller shall pay to Buyer the amount of such difference. Payment shall be made by wire transfer in immediately available funds. Payment by Buyer or Seller, as the case may be, shall be within five days of the Final Settlement Date.

(b) Final Settlement Dispute Resolution. If the parties are unable to resolve a dispute as to the Final Purchase Price by 45 days after Buyer’s receipt of Seller’s proposed Final Settlement Statement, the parties shall submit the dispute to binding arbitration to be conducted in accordance with the following procedures by a mutually acceptable independent public accounting firm selected by the parties (the “Accountants”). No later than 20 days after initiating the arbitration procedure, the Accountants shall conduct a hearing, at which time 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 Accountants shall consider any evidence and testimony that they determine to be relevant, in accordance with procedures that they determine to be appropriate. The Accountants shall render their written decision specifically establishing the Final Purchase Price within 30 days after the hearing, which decision shall be final, conclusive and binding on Seller and Buyer. A decision may be filed in any court of competent jurisdiction and may be enforced by any party as a final judgment of such court. Without the consent of Seller and Buyer, the arbitration shall not determine any issues other than adjustments to be made pursuant to Sections 2.7 and 13.1(a); all other disputes shall be handled pursuant to the provisions of Sections 4.5, 5.5 and 15.16. The costs of the Accountants shall be borne one-half by Seller and one-half by Buyer.

13.2 Proceeds and Expenses.

Subject to the terms of this Agreement, from and after the Closing, Buyer shall be entitled to, and Seller shall promptly turn over to Buyer, all proceeds received by Seller relating to the Assets for periods from and after the Effective Time and Buyer shall be liable for all costs and expenses attributable to the Assets for periods from and after the Effective Time. Buyer shall promptly turn over to Seller all proceeds of production relating to the Assets, and all reimbursements of expenses previously paid by Seller, which are received by Buyer after the date hereof and which are attributable to the Assets for any period of time prior to the Effective Time.

13.3 Records.

As soon as practicable after Closing, Seller shall transfer the Records to Buyer. Seller may retain copies of the Records or, in the case of such files and records as to which the Lands comprise less than all of the land covered or affected thereby, originals of the Records (at Seller’s option). In the event that Seller does not retain originals or copies of certain Records, Seller shall have the right to review and copy the Records during standard business hours upon reasonable notice for so long as Buyer retains the Records. Buyer agrees that the Records will be maintained in compliance with all applicable Laws governing document retention.

13.4 Suspense Accounts.

Seller shall transfer to Buyer only those monies held in suspense by Seller at Closing that relate to royalties and overriding royalties as to which Buyer shall be responsible for distribution after Closing. In addition to the information set forth on Schedule 6.16, Seller agrees to provide to Buyer any information reasonably requested by Buyer regarding all of Seller’s accounts holding monies in suspense that will be transferred to Buyer together with a written explanation (as contained in Seller’s files) of why such monies are held in suspense or other information identifying the proper disposition of such monies. Buyer agrees to take and apply such monies in a manner consistent with applicable Law and with prudent oil and gas business practices and to indemnify Seller against any claim relating to the failure to pay such funds after the Closing in accordance with the instructions or information delivered to Buyer by Seller.

13.5 Sales Tax.

Buyer shall pay all sales and transfer taxes, if any, occasioned by the sale of the Assets to Buyer and all documentary, filing and recording fees required in connection with the filing and recording of the assignments of the Assets to Buyer.

13.6 Further Assurances.

From time to time after Closing, Seller and Buyer shall each execute, acknowledge and deliver to the other such further instruments and take such other action as may be reasonably requested in order to accomplish more effectively the purposes of the transactions contemplated by this Agreement.

13.7 Release of Escrow Funds and Shares.

Upon the expiration of Seller’s indemnity obligations set forth in Sections 14.1(a), (b), 14.1(c) and (e) (which expiration is on February 28, 2008 pursuant to Sections 14.6(a) and (b)), Seller shall be entitled to receive all amounts and/or Shares remaining in the Escrow Account except for those amounts subject to a timely Claim Notice by Buyer under Section 14.8(a). If at such time such a Claim Notice is pending but only Shares remain on deposit with the Escrow Agent, Buyer and Seller, acting reasonably, will agree to a number of Shares to be retained by the Escrow Agent as would provide reasonable adequate security for Buyer’s claim.

13.8 Removal of Name.

As promptly as practicable, but in any case within 30 days after the Closing Date, Buyer shall eliminate the name “Laramie Energy, LLC” and any variants thereof from the Assets acquired pursuant to this Agreement and, except with respect to such grace period for eliminating existing usage, shall have no right to use any logos, trademarks or trade names belonging to Seller or any of its Affiliates.

WITHOUT LIMITATION OF THE FOREGOING AND EXCEPT FOR SELLER’S WARRANTIES, THE ASSETS SHALL BE CONVEYED PURSUANT HERETO WITHOUT (A) ANY WARRANTY OR REPRESENTATION, WHETHER EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, RELATING TO (I) TITLE TO THE ASSETS, THE CONDITION, QUANTITY, QUALITY, FITNESS FOR A PARTICULAR PURPOSE, CONFORMITY TO THE MODELS OR SAMPLES OF MATERIALS OR MERCHANTABILITY OF ANY EQUIPMENT OR ITS FITNESS FOR ANY PURPOSE, (II) THE ACCURACY OR COMPLETENESS OF ANY DATA, REPORTS, RECORDS, PROJECTIONS, INFORMATION OR MATERIALS NOW, HERETOFORE OR HEREAFTER FURNISHED OR MADE AVAILABLE TO BUYER IN CONNECTION WITH THIS AGREEMENT, (III) PRICING ASSUMPTIONS, OR QUALITY OR QUANTITY OF HYDROCARBON RESERVES (IF ANY) ATTRIBUTABLE TO THE PROPERTIES OR THE ABILITY OR POTENTIAL OF THE PROPERTIES TO PRODUCE HYDROCARBONS, (IV) THE ENVIRONMENTAL CONDITION OF THE PROPERTIES, BOTH SURFACE AND SUBSURFACE, (V) ANY IMPLIED OR EXPRESS WARRANTY OF NON-INFRINGEMENT, OR (VI) ANY OTHER MATTERS CONTAINED IN ANY MATERIALS FURNISHED OR MADE AVAILABLE TO BUYER BY SELLER OR BY SELLER’S AGENTS OR REPRESENTATIVES, OR (B) ANY OTHER EXPRESS, IMPLIED, STATUTORY OR OTHER WARRANTY OR REPRESENTATION WHATSOEVER.

BUYER IS RELYING SOLELY UPON THE TERMS OF THIS AGREEMENT AND ITS OWN INSPECTION OF THE ASSETS, AND BUYER, SUBJECT TO THE TERMS OF THIS AGREEMENT, SHALL ACCEPT ALL OF THE SAME IN THEIR “AS IS, WHERE IS” CONDITION.

14.8 Procedure.

The indemnifications contained in Sections 14.1 and 14.3 shall be implemented as follows:

(a) Claim Notice. The party seeking indemnification under the terms of this Agreement (the “Indemnified Party”) shall submit a written notice (a “Claim Notice”) to the other party (the “Indemnifying Party”) which, to be effective, must state: (i) the amount of each payment claimed by an Indemnified Party to be owing, to the extent then quantifiable; (ii) the basis for such claim, with supporting documentation; and (iii) a list identifying to the extent

reasonably possible each separate item of Loss for which payment is so claimed. The amount claimed shall be paid by such Indemnifying Party as and to, and only to, the extent required herein within 30 days after receipt of the Claim Notice or after the amount of such payment has been finally established, whichever last occurs.

(b) Information. Within 60 days after notification to an Indemnified Party with respect to any claim or legal action or other matter that may result in a Loss for which indemnification may be sought under this Article XIV, but in any event in time sufficient for the Indemnifying Party to contest any action, claim, proceeding or other matter that has become the subject of proceedings before any court or tribunal, such Indemnified Party shall give written notice of such claim, legal action or other matter to the Indemnifying Party and, at the request of such Indemnifying Party, shall furnish the Indemnifying Party or its counsel with copies of all pleadings and other information with respect to such claim, legal action or other matter and shall, at the election of the Indemnifying Party made within 60 days after receipt of such notice, permit the Indemnifying Party to assume control of such claim, legal action or other matter (to the extent only that such claim, legal action or other matter relates to a Loss for which the Indemnifying Party is liable), including the determination of all appropriate actions, the negotiation of settlements on behalf of the Indemnified Party, and the conduct of litigation through attorneys of the Indemnifying Party’s choice; provided, however, that no such settlement can result in any liability or cost to the Indemnified Party for which it is not entitled to be indemnified hereunder, or subject the Indemnified Party to any declaratory, injunctive or other equitable relief or to regulatory sanctions or restrictions, without its consent. If the Indemnifying Party elects to assume control: (i) any expense incurred by the Indemnified Party thereafter for investigation or defense of the matter shall be borne by the Indemnified Party; and (ii) the Indemnified Party shall give all reasonable information and assistance, other than pecuniary, that the Indemnifying Party shall deem necessary to the proper defense of such claim, legal action, or other matter. In the absence of such an election, the Indemnified Party will use reasonable efforts to defend, at the Indemnifying Party’s expense, any claim, legal action or other matter to which the Indemnifying Party’s indemnification under this Article XIV applies until the Indemnifying Party assumes such defense, and, if the Indemnifying Party fails to assume such defense within the time period provided above, settle the same in the Indemnified Party’s reasonable discretion at the Indemnifying Party’s expense.

(c) Dispute. If the existence of a valid claim or amount to be paid by an Indemnifying Party is in dispute, the parties agree to submit determination of the existence of a valid claim or the amount to be paid pursuant to the Claim Notice to the dispute resolution mechanism set forth in Section 15.16.

14.9 Reservation as to Non-Parties.

Nothing herein is intended to limit or otherwise waive any recourse Buyer may have against any Person other than the Seller Indemnified Parties, or which Seller may have against any Person other than Buyer, for any obligations or liabilities which may be incurred with respect to the Assets.

14.10 Exclusive Remedy.

The sole and exclusive remedy of Buyer with respect to the Assets shall be pursuant to the express provisions of this Agreement. Without limitation of the foregoing, if the Closing occurs the sole and exclusive remedy of Buyer, for any and all (a) claims relating to any representations, warranties, covenants and agreements that are contained in this Agreement or in any certificate delivered at Closing, (b) other claims pursuant to or in connection with this Agreement, and (c) other claims relating to the Assets and the purchase and sale thereof, shall be any right to indemnification from such claims that is expressly provided in this Article XIV, and if no such right of indemnification is expressly provided, then such claims are hereby waived to the fullest extent permitted by law. If the Closing occurs, Buyer shall also be deemed to have waived, to the fullest extent permitted under applicable law, any right to contribution against Seller (including, without limitation, any contribution claim arising under any applicable Environmental Law) and any and all other rights, claims and causes of action it may have against Seller arising under or based on any federal, state or local statute, law, ordinance, rule or regulation or common law or otherwise.

14.11 Waiver of Right to Rescission.

Seller and Buyer acknowledge that the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated in this Agreement. As the payment of money shall be adequate compensation, Buyer and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.
