c.             In the event a third party validly exercises an applicable Preferential Purchase Right prior to Closing, the Purchase Price shall be reduced by the Allocated Value of the applicable Property, as set forth in Exhibit A.  The existence of an unwaived Preferential Purchase Right with respect to a transaction contemplated by this Agreement shall not be deemed a Title Defect, but shall be governed by the provisions of Section 10.03.

d.             Subject to Buyer’s rights under other provisions of this Agreement, if the Title Defect is a lien, encumbrance or other charge upon a Property which is liquidated in amount, the Purchase Price shall be reduced by the sum necessary to be paid to the obligee to remove the Title Defect from the affected Property.  Subject to Buyer’s rights under other provisions of this Agreement, if a Title Defect represents an obligation or burden upon the affected Property for which the economic detriment to Buyer is not capable of being liquidated but can be estimated with reasonable certainty, the Purchase Price shall be reduced by the sum necessary to compensate Buyer at Closing for the adverse economic effect which such Title Defect will have on the affected Property.  If there is a lien or encumbrance in the form of a judgment secured by superseded bond or other security approved by the Court issuing such order, in an amount not less than the Allocated Value for the affected Property, such lien or encumbrance shall not be considered a Title Defect within meaning of this Agreement.

10.02       Closing Title Adjustment Provisions.

a.             With respect to undisputed Title Defects, upon receipt of a notice set forth in Section 10.01 (b) above, Seller shall have the right, prior to Closing, to cure all, or any portion of the undisputed Title Defect at its sole cost and expense.

b.             In the event an increase or decrease in the Net Revenue Interest with respect to a particular Property (or group thereof) is discovered during the Title Review Period which would result in an increase or decrease in the Purchase Price, the amount of any required Purchase Price adjustment shall be determined in accordance with the following procedure:

When a Title Defect is based upon the fact that Seller owns a lesser or greater Net Revenue Interest than that shown with respect to a particular Property (or group thereof) in Exhibit A hereto, then (provided the applicable working interest changes proportionately with the change in the Net Revenue Interest) the Allocated Value of such interest in Exhibit A shall be reduced or increased (as the case may be) in the same proportion that the actual Net Revenue Interest bears to the Net Revenue Interest shown therefore in Exhibit A, to-wit:

Actual Net Revenue Interest  x  Allocated Value Exhibit A, Net Revenue Interest

c.             In the event Seller is unable or unwilling to cure any undisputed Title Defect prior to Closing, Seller shall attempt to negotiate with Buyer for a mutually agreeable reduction in the Purchase Price for such defect prior to Closing, and in the event of such reduction agreed upon, the affected Property shall be conveyed to Buyer subject to such defect.

d.             If a Title Defect involves a claim or question to a Seller’s title to a particular Property (or group thereof) other than a lien or encumbrance provided for herein under Section

26

10.01 (d) and Seller is unable or unwilling to cure any undisputed Title Defect prior to closing, Seller and Buyer shall attempt to negotiate a mutually agreeable reduction in the Purchase Price for such defect prior to Closing, and in the event of such reduction in the Purchase Price, the affected Property shall be conveyed to Buyer subject to such defect.

10.03       Preferential Purchase Rights and Consents.  As represented by Seller under Section 5.12, all Preferential Purchase Rights affecting the Properties known to Seller are set forth in Exhibit H. Should Buyer or Seller discover additional Preferential Purchase Rights, it shall promptly inform the other so that such rights may be resolved in accordance with the provisions hereof.  All Preferential Purchase Rights, whether or not appearing on Exhibit H, which affect the Properties shall be resolved or treated in accordance with the following provisions:

a.             If a third party who has been offered an interest in all or any portion of the Properties pursuant to a Preferential Purchase Rights elects prior to Closing to purchase all or any portion of the Properties pursuant to such offer, and Seller receives notice of such election prior to Closing, Buyer may elect to terminate this Agreement without any further obligation.  However, provided that Buyer elects not to terminate this Agreement, the Properties (or portion thereof so affected) will be eliminated from the transactions contemplated hereby, the Purchase Price shall be reduced by the Allocated Values for the Properties (or portion thereof so affected) and the interest offered shall be conveyed to Buyer at Closing subject to the Preferential Purchase Right of such third party. If such third party elects to purchase all or any portion of an interest in the Properties and Closing has already occurred (and payment of the Purchase Price with respect thereto made by Buyer), Buyer shall be obligated to convey such interest to such third party, and shall be entitled to receive the entire consideration from such third party for the sale of such interest or portion thereof.

b.             Seller and Buyer shall each use reasonable efforts to obtain all consents to assignment prior to Closing (other than rights to consent constituting Permitted Encumbrances).  If a lessor or other third party having a valid, contested right to consent to an assignment of a Property (or portion thereof) refuses to provide such consent prior to Closing (and such refusal could render Seller’s assignment thereof void or voidable), the interest or portion thereof shall be deemed to be burdened by a Title Defect, and the provisions of Section 10.02 shall be applicable.

10.04       Title Defect Disputes and Unresolved Title Defects.

a.             It is recognized that good faith differences of opinion may exist between Seller and Buyer regarding asserted Title Defects.  These differences of opinion or “Title Defect Disputes” include, without limitation, disputes as to (a) whether or not the defect constitutes a Title Defect within the meaning of the Agreement, (b) whether or not the magnitude of an asserted Title Defect is great enough that Buyer is contractually entitled to assert a Title Defect, and, (c) whether or not the asserted Title Defect was properly and timely asserted by Buyer.

b.             Seller and Buyer shall meet at least four (4) Business Days before the Closing Date to attempt to mutually agree on a proposed resolution with respect to any unresolved Title Defects or Title Defect Dispute(s).

c.             Closing shall not be delayed, postponed or canceled because the parties cannot agree prior to the Closing Date on an adjustment to the Purchase Price resulting from unresolved

27

Title Defects or Title Defect Dispute(s). If any such difference of opinion regarding the adjustment to the Purchase Price for  Title Defects or Title Defect Dispute(s) are not resolved by mutual agreement of Buyer and Seller prior to the Closing Date, the parties shall consummate the transaction using the Seller’s numbers; provided however, either party shall have the right, exercisable within fifteen (15) Business Days after the Closing Date, to refer the same to arbitration using a neutral arbitrator who is an attorney licensed in the State of Colorado and who has at least fifteen (15) years oil and gas title experience and who has never been an officer, director, employee, consultant, agent or representative of either Seller or Buyer. If such arbitrator is unwilling or unable to serve as the arbitrator, Seller and Buyer shall again attempt to select an acceptable arbitrator.  If the parties are unable to agree upon the selection and designation of an acceptable arbitrator, then Seller or Buyer shall request the American Arbitration Association to select a qualified arbitrator. Seller, Buyer and the arbitrator shall proceed diligently and in good faith in order that the arbitration is commended and completed as promptly as possible. The arbitration shall be conducted in Denver, Colorado, and in accordance with the Uniform Arbitration Act, as adopted and then in effect in the State of Colorado.  The expenses of the arbitration, including the arbitrator’s fees, shall be divided equally between Seller and Buyer.  Each party shall pay the fees and expenses of its own witnesses and legal counsel, unless otherwise specified in the award. Any arbitration decision shall be final and conclusive upon Buyer and Seller, it being expressly understood and agreed by the parties that the specific issue or issues so determined shall not be the subject of (i) any further dispute between the parties, (ii) any further arbitration under this Section, or (iii) judicial appeal.

d.             Furthermore, Buyer or Seller shall have the right to terminate this Agreement on the Closing Date if the value attributable to asserted Title Defect(s) which remain uncured or unresolved as of the Closing Date exceeds ten percent (10%) of the unadjusted Purchase Price.

ARTICLE XI

POST CLOSING MATTERS

11.01       Post Closing Matters.  The provisions of this Article XI shall apply after Closing:

a.             Seller’s responsibility for conducting the accounting for the Properties shall cease with production attributable to the calendar month during which Closing occurs, and Buyer shall thereafter be responsible for conducting such accounting; provided, however, that if Closing occurs on the first day of a month, it shall be deemed, for purposes of this subparagraph, that Closing occurred on the last day of the preceding month.  Seller shall provide Buyer with a statement of accounting covering the period from the Closing Date through the end of the calendar month in which Closing occurs.

b.             Should Buyer receive any proceeds of production or any invoices for any expenses attributable to production from the Properties prior to the Effective Date, Buyer shall promptly remit the same to Seller.

c.             Should Seller receive any proceeds of production or any invoices for any expenses attributable to production from the Properties after the Effective Date, Seller shall promptly forward the same to Buyer.

28

11.02       Seller’s Right to Records.  Seller shall be entitled to retain the following Records respecting the Properties and shall be permitted access, as herein below set forth, to the Records delivered by Seller hereunder with respect to the Properties:

a.             Buyer recognizes that certain Records of Seller may contain only incidental information relating to the Properties and that Seller may, after review by and with the consent of Buyer, retain such Records;

b.             Seller may retain (i) one copy of all Records, and (ii) all originals and copies of all documents prepared or received by Seller in connection with the transaction and sale of the Properties contemplated herein;

c.             Seller may retain all financial information, tax records and all other accounting data prepared or used in connection with the financial statements prepared by Seller and made available to Buyer in the Data Room;

d.             Seller shall be permitted reasonable access, for a period of seven (7) years after Closing, to Records relating to the Properties for tax and financial accounting purposes.  For this purpose, Buyer agrees to retain and preserve the Records for such seven (7) year period following Closing; provided that Buyer may sell a Property and transfer the Records attributable to such Property to a purchaser if the purchaser agrees to be bound by and comply with the provisions of this section 11.02(d).

ARTICLE XII

INDEMNIFICATION

12.01       Article XII Definitions.  As used in this Article XII the following terms shall have the meanings set forth below:

29

12.02       Indemnity by Seller.  Except as separately and specifically provided for under Section 9.03 above with respect to indemnification for Environmental Liabilities, Seller and its successors and permitted assigns shall, to the fullest extent permitted by law, indemnify, defend, hold harmless, discharge and release Buyer and its Affiliates, successors and permitted assigns, stockholders, directors, officers, employees, agents and representatives from and against the following:

a.             Losses Resulting from Third Party Indemnity Claims.  Losses resulting from Third Party Indemnity Claims arising from the breach by Seller of any representations or warranties under Article V hereof to the extent, and only to the extent that (i) such representations or warranties survive Closing under Section 18.01 below, and (ii) such Third Party Indemnity Claims arise and are communicated in writing to Seller prior to the expiration of eighteen (18) months following the Closing Date.

c.             Other Liabilities.  Losses arising from, based on or caused by (i) Seller Environmental Liabilities, (ii) any act, omission or event involving or relating to the Properties occurring prior to the Effective Date other than Buyer Environmental Liabilities, or (iii) the ownership or operation of the Properties prior to the Effective Date other than Buyer Environmental Liabilities, to the extent and only to the extent that Buyer’s claim based thereon is communicated in writing to Seller prior to the expiration of eighteen (18) months following the Closing Date.

12.03       Indemnity by Buyer.  Except as separately and specifically provided under Section 9.03 above with respect to Indemnification for Environmental Liabilities, Buyer and its successors and permitted assigns shall, to the fullest extent permitted by law, indemnity, defend, hold harmless, discharge and release Seller and its Affiliate, successors and permitted assigns, stockholders, directors, officers, employees, agents and representatives from and against the following:

a.             Third Party Indemnity Claims.  Losses resulting from Third Party Indemnity Claims arising from the breach by Buyer of any representations or warranties under Article VI hereof, to the extent and only to the extent that Seller’s claim based thereon is communicated to Buyer prior to the expiration of eighteen (18) months following the Closing Date.

b.             Claims of Seller.  Losses arising from the breach by Buyer of any representations or warranties under Article VI hereof, to the extent and only to the extent that Seller’s claim based thereon is communicated to Buyer prior to the expiration of eighteen (18) months following the Closing Date.

30

occurring on or after the Closing Date, or (iii) the ownership or operation of the Properties on or after the Closing Date.

12.04       Demands.  Any Indemnitee hereunder agrees that promptly upon its discovery of facts giving rise to a claim for indemnity under the provisions of this Agreement, including receipt by it of notice of any Third Party Indemnity Claim, with respect to any matter as to which it claims to be entitled to indemnity under the provisions of this Agreement, it will give prompt notice thereof in writing to the Indemnitor, together with a statement of such information respecting any of the foregoing as it shall have, an estimate of the amount of the claim and the approximate date(s) upon which the breach, act, omission or event occurred.  Such notice shall include a formal demand for indemnification under this Agreement.  The Indemnitor shall not be obligated to indemnify the Indemnitee with respect to any Third Party claim if the Indemnitee knowingly failed to notify Indemnitor or its counsel to defend against such matter and to make a timely response thereto including, without limitation, any responsive motion or answer to a complaint, petition, notice or other legal, equitable or administrative process relating to the Third Party Indemnity Claim, only insofar as such knowing failure to notify the Indemnitor actually resulted in prejudice or damage to the Indemnitor.

12.05       Right to Contest and Defend.  The Indemnitor is entitled at its cost and expense to contest and defend by all appropriate legal proceedings any Third Party Indemnity Claim with respect to which it is called upon to indemnify an Indemnitee under the provisions of this Agreement; provided, that notice of the intention to so contest shall be delivered by the Indemnitor to the Indemnitee within twenty (20) calendar days from the date of receipt by Indemnitor of written notice by the Indemnitee of the assertion of the Third Party Claim.  Any such contest may be conducted in the name and on behalf of the Indemnitor or the Indemnitee as may be appropriate.  Such contest shall be conducted by reputable counsel employed by Indemnitor, but the Indemnitee shall have the right to participate in such proceedings and to be represented by counsel of its own choosing at its sole cost and expense.  If the Indemnitee joins in any such contest, the Indemnitor shall have full authority to determine all action to be taken with respect thereto; provided, however, that the Indemnitor will not have the authority to subject the Indemnitee to any obligation whatsoever, other than the performance of purely ministerial tasks (e.g. the execution of settlement agreements and other documentation) or obligations not involving material expense.  If the Indemnitor does not elect to contest any such claim, any Indemnitor shall be bound by the result obtained with respect thereto by the Indemnitee.  At any time after the commencement of the defense of any Third Party Indemnity Claim, the Indemnitor may request the Indemnitee to agree in writing to the abandonment of such contest or to the payment or compromise by the Indemnitor of the asserted Third Party Indemnity Claim, whereupon such action shall be taken unless the Indemnitee determines that the contest should be continued, and so notifies the Indemnitor in writing within fifteen (15) calendar days of such request from the Indemnitor.  If the Indemnitee determines that the contest should be continued, the Indemnitor shall be liable hereunder only to the extent of the amount that the other party to the contested Third Party Indemnity Claim had agreed unconditionally to accept in payment or compromise as of the time the Indemnitor made its request therefor to the Indemnitee.

12.06       Cooperation.  If requested by the Indemnitor, the Indemnitee agrees to cooperate with the Indemnitor and its counsel in contesting any Third Party Indemnity Claim that the Indemnitor elects to contest or, if appropriate, in making any counterclaim against the person asserting the

31

Third Party Indemnity Claim, or any cross-complaint against any person, but the Indemnitor will reimburse the Indemnitee for any expenses incurred by it in so cooperating.

12.07       Right to Participate.  The Indemnitor agrees to afford the Indemnitee and its counsel the opportunity to be present at, and to participate in, conferences with all persons, including governmental authorities, asserting any Third Party Indemnity Claim against the Indemnitee or conferences with representatives of or counsel for such persons.

12.08       Payment of Damages.  The Indemnitor shall pay to the Indemnitee in immediately available funds the amount of any monies to which the Indemnitee may become entitled by reason of the provisions of this Article XII (and Section 9.03), such payment to be made within ten (10) calendar days after any such amount is finally determined either by mutual agreement of the parties hereto or pursuant to the final unappealable judgment of a Court of competent jurisdiction.

12.09       No Insurance; Subrogation.  The indemnifications provided in this Article XII shall not be construed as a form of insurance and shall be binding upon and incur to the benefit of Seller, Buyer and their respective Affiliates, successors and permitted assigns.  To the extent enforceable under existing insurance contracts and applicable laws, Seller and Buyer hereby waive for themselves, their Affiliates, successors and permitted assigns, including without limitation any insurers, any rights to subrogation for Losses for which each of them is respectively liable or against which each respectively indemnifies the other, and, if necessary, said parties shall obtain waiver of such subrogation from their respective insurers.

ARTICLE XIII

TAX MATTERS

13.01       Allocation of Tax Liability.  The obligations of the parties with respect to ad valorem and property taxes relating to the Properties shall be allocated based upon the Effective Date.  Seller is responsible for payment of all ad valorem and property taxes allocable to periods prior to the Effective Date.  Buyer is responsible for payment of all ad valorem and property taxes allocable to the Properties for periods from and after the Effective Date.

13.02       Sales and Transfer Tax Liability.  The Purchase Price provided for hereunder excludes any sales taxes or other taxes in connection with the sale of the Properties pursuant to the Agreement.  If a determination is ever made that a sales tax or other transfer tax applies, Buyer shall be solely liable for all of such taxes, as well as for any applicable conveyance, transfer and recording fees, real estate transfer stamps or taxes imposed on the transfer of property to Buyer pursuant to this Agreement.  Buyer shall defend, indemnify and hold Seller harmless with respect to payment of all such taxes, if any, including any interest or penalties assessed thereon.

13.03       Exchange.  Seller or Buyer may desire to structure the sale and purchase of the Properties as part of an exchange under Section 1031 of the Code.  In this regard, Seller and Buyer agree to execute all documents, conveyances and other instruments reasonably necessary to effectuate an exchange.

32

ARTICLE XIV

GAS MATTERS

14.01       Gas Imbalance Issues.  Seller has provided in Section 5.11 hereof a representation regarding known gas imbalances with respect to production from or attributable to certain of the Properties as of the Effective Date.  Any variance of the actual net imbalance from the estimated amounts set forth in Exhibit F, which are discovered by Buyer and confirmed by Seller prior to Closing, shall result in an adjustment to the Purchase Price, as provided in Sections 3.02 (b)(ii) and 3.03. If Closing occurs, Buyer shall bear all obligations with respect to any net overproduction liability and shall receive the benefit of and be credited with any net underproduction credit, including overproduction and underproduction attributable to periods of time prior to the Effective Date.

ARTICLE XV

CASUALTY AND CONDEMNATION

15.01       Casualty and Condemnation.  If a substantial part of the Properties shall (a) be destroyed prior to Closing by a Casualty Loss, or (b) be taken in condemnation or if proceedings for such purposes shall be pending; then either Buyer or Seller may terminate this Agreement prior to the Closing.  For the purpose of this Section 15.01, the term “substantial” shall mean that the Allocated Value of the Properties affected by the Casualty Loss or Condemnation constitutes twenty percent (20%) of the unadjusted Purchase Price.  If either party terminates this Agreement pursuant to this Article, neither party shall have any further obligation.  If neither party terminates this Agreement, Seller and Buyer shall attempt to agree on a reduction in the Purchase Price reflecting the actual reduction of the value to Buyer of the Property(s) affected by the Casualty Loss or Condemnation.  Seller shall retain any and all sums paid to Seller, insurance proceeds and other payments associated with or attributable to such Casualty Loss or taking.

ARTICLE XVI

TERMINATION

16.01       Grounds for Termination.  This Agreement may be terminated at any time prior to the Closing Date:

a.             by the mutual written agreement of Seller and Buyer;

b.             by Buyer in the event Buyer has not obtained financing from external sources for the payment of the Purchase Price upon satisfactory terms and conditions by the Closing Date or by an extended Closing Date pursuant to Section 16.02;

c.             by Seller or by Buyer if the Closing shall not have occurred by June 30, 2011 (or such other date, if any, as Seller and Buyer shall have agreed in writing), provided the failure to close on or before such date is not caused by any breach of this Agreement by the party electing to terminate pursuant to this Section 16.01(c);

d.             by Seller or by Buyer if the purchase and sale of the Properties would violate any nonappealable final order, decree or judgment of any Court or governmental body having competent jurisdiction;

33

e.             by Seller or Buyer in the event of a material breach or default hereunder which remains uncured after five (5) days written notice from the non-breaching party; or

f.              by Seller or Buyer under any other provision under this Agreement providing for Seller’s or Buyer’s right to terminate.

16.02       Non-Refundable Deposits.  On May 20, 2011, Buyer shall deliver to Seller a non-refundable deposit of $100,000, which shall be credited against the Purchase Price if the transaction closes or which shall be retained by Seller if the transaction fails to close.  If on June 15, 2011, the scheduled Closing Date, Buyer has not secured the necessary funds to close the transaction, it may extend the Closing Date to 10:00 a.m., MDT, on June 22, 2011, by delivering to Seller on or before 10:00 a.m., MDT, on June 15, 2011, an additional non-refundable deposit of $100,000.  If on June 22, 2011, Buyer has secured the necessary funds to close the transaction, but it requires additional time to access such funds, then Buyer may again extend the Closing Date to 10:00 a.m., MDT, on June 30, 2011, by delivering to Seller on or before 10:00 a.m., MDT, on June 22, 2011, an additional non-refundable deposit of $150,000.  This shall be the final extension of the Closing Date under this Agreement.  If the transaction closes pursuant to this Agreement, all of the non-refundable deposits delivered by Buyer pursuant to this Section 16.02 shall be credited against the Purchase Price.  If the transaction fails to close, Seller may retain all such non-refundable deposits delivered by Buyer pursuant to this Section 16.02; provided, however, that Seller shall return all of such non-refundable deposits to Buyer if this Agreement is terminated (i) by Buyer pursuant to a provision of this Agreement that provides Buyer with a right of termination, (ii) by Buyer as a result of Seller’s breach or default hereunder or (iii) by mutual agreement of the parties.

16.03       Effect of Termination.  If this Agreement is terminated by Seller or Buyer as the result of the other party’s material breach or default hereunder, then the non-defaulting party shall have the right to enforce the specific performance of this Agreement against the defaulting party in lieu of monetary damages for such breach or default.

ARTICLE XVII
