ARTICLE II

          2.1 Contribution of Assets; Assumption of Liabilities. At the Closing, upon the terms and subject to the conditions set forth in this Agreement, Contributor shall contribute, assign, transfer and convey to Contributee (or to an entity or entities wholly-owned, directly or indirectly, by Contributee which is or are disregarded for Federal income Tax purposes and to which Contributee shall, prior to Closing, have assigned in writing its rights, but not its obligations, hereunder), and Contributee, or its assignee(s), shall acquire from Contributor, the Assets, free and clear of any Liens other than Permitted Liens, and Contributee, or its assignee(s), shall assume all of the liabilities and obligations associated with the Assets from and after the Effective Time, provided with respect to Contracts it shall be an assumption of all of the liabilities and obligations other than those accruing or arising from a breach or default by the Contributor prior to the Effective Time (the “Assumed Liabilities”).

          2.2 Issuance of Contributee Units at Closing. Subject to Section 2.4, in exchange for the contribution of the Assets and assumption of the Assumed Liabilities, at the Closing, Contributee shall deliver to Contributor the number of Common Units equal to the quotient of (i) the Agreed Value (as computed in accordance with Section 2.3), divided by (ii) the Unit Price (the “Contributee Units”). Notwithstanding the date of delivery of the Contributee Units, Contributor hereby waives any and all rights to receive any distribution by Contributee relating to the three month period ending June 30, 2007, whenever such distribution is declared and regardless of whether Contributor acquires the Contributee Units prior to the setting of any record date with respect to such distribution. The parties hereto agree that such waiver is based on the fact that Contributor will not own any Contributee Units during the three month period ending June 30, 2007 and not the result of any failure of Contributee to fund such distribution to Contributor.

          2.3 Computation of Agreed Value. For purposes of this ARTICLE II and the remainder of this Agreement, “Agreed Value” shall mean $27,500,000.00, increased and decreased as applicable, by the following amounts which shall be set forth on a settlement statement (the “Preliminary Settlement Statement”) prepared by the Contributor and agreed to by the Contributee prior to the Closing. (a) The Agreed Value shall be increased by an amount equal to the sum of the following amounts:

     (i) An amount equal to the costs and expenses that are (1) attributable to the Assets for the period after the Effective Time, whether paid before or after the Effective Time, and (2) paid by Contributor, including, without limitation, bond and insurance premiums paid by or on behalf of Contributor attributable to coverage for obligations or benefits extending beyond the Effective Time up to and including, but not beyond, the Closing Date;

     (ii) An amount equal to the proceeds received by Contributee for the sale of oil, gas or other minerals produced from the Assets before the Effective Time in storage or in pipelines on the Effective Time (excluding such production constituting line-fill in pipelines and such production below the outlet flange on storage tanks) net of all applicable taxes and royalties;

     (iii) The amount of all prepaid ad valorem, property, and similar Taxes and assessments based upon or measured by ownership of the Assets and attributable to periods of time after the Effective Time; and

     (iv) Any other amount agreed upon by Contributee and Contributor.

     (b) The Agreed Value shall be decreased by an amount equal to the sum of the following amounts:

     (i) The amount of all proceeds received by Contributor, net of all applicable Taxes actually paid, attributable to the Assets for periods of time after the Effective Time, excluding, however, proceeds attributable to production prior to the Effective Time;

     (ii) An amount equal to the sum of any costs and expenses paid by Contributee that are attributable to the Assets for periods prior to the Effective Time;

     (iii) An amount equal to all ad valorem, property, and similar Taxes and assessments based upon or measured by the ownership of the Assets that are unpaid as of the Closing Date and attributable to periods of time prior to the Effective Time, which amounts shall be computed based upon such Taxes and assessments for the calendar year in which the Effective Time occurs; provided that if such Taxes have not been actually assessed for such calendar year as of the Closing Date, such amounts will be initially computed based on such Taxes and assessments for the preceding Tax year, and will be subsequently adjusted based upon the actual Taxes for the current calendar year once those amounts are assessed; and

     (iv) Any other amount agreed upon by Contributor and Contributee.

          2.4 Escrow Deposit. At Closing, the Escrow Deposit shall be deposited in the Escrow Account with the Escrow Agent pursuant to the terms and conditions of the Escrow Agreement.

          2.5 Determination of Final Agreed Value; Post-Closing Adjustments; and Post-Closing Remittance Obligations.

     (a) Contributor shall, within one hundred twenty (120) days after the Closing Date, prepare and submit for Contributee’s review, in accordance with this Agreement and with generally accepted accounting principles consistently applied, a statement (the “Final Settlement Statement”) setting forth each adjustment to the Agreed Value necessary to determine the Final Settlement Statement and showing the calculation of such adjustments (the “Final Agreed Value”). The Parties shall undertake to agree on the Final Settlement Statement and the Final Agreed Value no later than one hundred fifty (150) days after the Closing Date with respect to all of the Assets. If the Final Agreed Value is more than the Agreed Value, Contributee shall pay such difference to Contributor in additional Contributee Units within five (5) Business Days after the Parties have agreed upon the Final Settlement Statement, with no portion of said additional issuance of Contributee Units being subject to or becoming part of the Escrow Deposit. If the Final Agreed Value is less than the Agreed Value, Contributor shall, at Contributor’s sole election, either (i) pay the amount of such difference to Contributee by wire transfer in immediately available funds or (ii) forfeit to Contributee that number of Contributee Units held in the Escrow Deposit equal to the quotient of (A) the amount of the difference between the Final Agreed Value and the Agreed Value, divided by (B) the

Unit Price within five (5) Business Days after the Parties have agreed upon the Final Settlement Statement. If Contributor and Contributee cannot agree upon the Final Settlement Statement, Deloitte & Touche, LLP, or such other nationally recognized accounting firm as may be accepted by both Contributee and Contributor, shall act as an arbitrator and decide all points of disagreement with respect to the Final Settlement Statement, whose decisions shall be binding upon the parties. The costs and expenses of such accounting firm shall be borne fifty percent (50%) by Contributor and fifty percent (50%) by Contributee.

     (b) After the Final Settlement Statement and the Final Agreed Value have been computed and agreed upon (or settled by Deloitte & Touche pursuant to Section 2.5(a)), then any additional amounts which are received by either Contributor or Contributee on account of production with respect to the Assets after the Effective Time, or prior to the Effective Time, respectively, and which were not taken into account in calculation of the Final Settlement Statement and Final Agreed Value, shall be remitted within fifteen (15) Business Days by Contributor, or Contributee, respectively, to Contributee, or Contributor, respectively.

          2.6 Tax Treatment of Adjustments to Agreed Value and Payments.

ARTICLE VII
TAX MATTERS

          7.1 Character and Treatment of Transaction.

     (a) Contribution Transaction. Contributee and Contributor agree to treat the contribution of the Assets pursuant to Section 2.1 and Section 2.2 as a contribution by Contributor to the Contributee in exchange for Contributee Units pursuant to Code Section 721(a) and the Regulations promulgated thereunder.

     (b) Valuations and Allocations. The parties shall agree to an allocation of the Agreed Value among the Assets prior to the Closing Date (the “Allocation”).

     (c) Allocation Consistency. Contributor and Contributee shall report the transactions contemplated hereby on all Tax Returns, including, but not limited to, for purposes of future allocations under Code Section 704(c), in a manner consistent with the Allocation. If, contrary to the intent of the parties hereto as expressed in this Section 7.1(c), any Taxing authority makes or proposes an allocation different from the Allocation, Contributor and Contributee shall cooperate with each other in good faith to contest such Taxing authority’s allocation (or proposed allocation), provided, however, that, after consultation with the party (or parties) adversely affected by such allocation (or proposed allocation), the other party (or parties) hereto may file such protective claims or Tax Returns as may be reasonably be required to protect its (or their) interests.

          7.2 Post-Closing Tax Covenants. Contributee covenants that until the earlier of (i) two (2) years following the Closing Date or (ii) the date that all of the Contributee Units transferred pursuant to Section 2.2 have been sold in a transaction resulting in a basis adjustment under Code Section 743 for the benefit of the transferee, that Contributee and its Affiliates will not dispose of any of the Assets acquired by Contributee pursuant to Section 2.1 if any such disposition or series of dispositions would accelerate any “built-in gain” (as defined in Regulation 1.704-3(a)(3)(ii)) in any such Asset with respect to the Contributee Units transferred to the Contributor pursuant to Section 2.2; provided, however, that Contributee may sell or dispose of any such Assets provided Contributee indemnifies the applicable Contributor for any such accelerated built-in gain allocable to such Contributor. Any such indemnification payment (Y) shall equal an amount obtained by dividing the amount of Tax payable by the ultimate partners of the Contributor resulting from such accelerated built-in gain (X) by the fraction obtained by subtracting from 1 the percentage (expressed as a number) equal to the highest

marginal Federal income tax rate applicable to individuals for the year such built-in gain is recognized (for example, if the highest such tax rate is 35%, the number would be .35) (here Z). Thus, the amount of such indemnification payment (Y) may be derived by the following formula:

Y = X/1 – Z

Any disputes regarding the amount of such indemnification payment shall be resolved as set forth in Section 7.4 below.

          7.3 Transfer Taxes. Contributor and Contributee shall be jointly responsible for state or local transfer, sales, use, stamp, registration or other similar Taxes resulting from the transactions contemplated by this Agreement.

          7.4 Disputes over Tax Provisions. If the Parties cannot agree, after good faith consultation, on the calculation of any Taxes that would result in a payment hereunder by one to the other or an adjustment of the Agreed Value, then each Party shall deliver simultaneously to BDO ▇▇▇▇▇▇▇, LLP (or if such firm is unwilling or unable to serve, another nationally recognized accounting firm mutually agreed on by the Parties, the accounting firm ultimately chosen being referred to herein as the “Accountants”) such work papers and other reports and information relating to the disputed matter(s) as the Accountants may request and shall be afforded the opportunity to discuss the disputed matter(s) with the Accountants. The Accountants shall have thirty (30) days to carry out a review and prepare a written statement of its determination regarding the disputed matter(s) (including a statement regarding the Accountants’ determination of the prevailing Party in any such disputed matter) which determination shall be final and binding upon the Parties. Any fees and expenses of the Accountants incurred in resolving the disputed matter(s) shall be borne equally by the Parties.

          7.5 Limitations on Indemnity. Except with regard to the indemnity provided by Section 7.2 above, this ARTICLE VII shall be expressly subject to the limits on indemnity set forth in ARTICLE IX hereof.

     (b) From and after the Closing and for the time period specified in Section 9.1, Contributee will indemnify, defend and hold harmless Contributor and its officers, members, directors, employees and Affiliates (the “Contributor Indemnified Parties”) against any and all Losses incurred or suffered as a result of, relating to or arising out of (i) any failure of any representation or warranty made by Contributee in this Agreement to be true and correct as of the Closing (as if made anew at and as of the Closing), (ii) the breach of any covenant or agreement made or to be performed by Contributee pursuant to this Agreement, and (iii) the Assumed Liabilities, the ownership of the Contributor, or the ownership or operation of Assets or the business of the Contributor, after the Effective Time.

     (c) THE INDEMNIFICATION PROVISIONS IN THIS ARTICLE IX SHALL BE ENFORCEABLE REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SINGLE NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY INDEMNIFIED PARTY, OR (ii) STRICT LIABILITY. THE PARTIES HERETO AGREE THAT THE FOREGOING COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

          9.3 Limitations on Liability. Notwithstanding anything to the contrary in this Agreement, in the event a Contributee Indemnified Party has a claim for indemnification under Section 9.2 hereof:

     (a) Neither a Contributee Indemnified Party nor a Contributor Indemnified Party will be entitled to indemnity under Section 9.2(a)(i), Section 9.2(a)(iii) or Section 9.2(b)(i) of this Agreement with respect to claims for Losses until the aggregate amount for all claims for Losses exceeds $750,000 (the “Aggregate Basket Amount”), and thereafter, the Contributee Indemnified Parties shall be entitled to indemnity for the aggregate amount of all individual claims for Losses in excess of the Aggregate Basket Amount.

     (b) In the event a Contributee Indemnified Party is entitled to indemnity under Section 9.2(a)(i) (for breach of representations and warranties which survive one (1) year or less after the Closing Date) and Section 9.2(a)(iii), any such claim may be satisfied solely and exclusively against the Escrow Deposit. Therefore, the maximum aggregate liability of Contributor under Section 9.2(a)(i) (for breach of representations and warranties which survive one (1) year or less after the Closing Date) and Section 9.2(a)(iii) of this Agreement shall not exceed the Escrow Deposit, and Contributee Indemnified Parties shall have no further right to indemnity thereunder at such time as all cash or Contributee Units have been disbursed from the Escrow Account. Under no circumstance shall a Contributee Indemnified Party be entitled to recover an indemnity claim arising under Section 9.2(a)(i) (for breach of representations and warranties which survive one (1) year or less after the Closing Date) and Section 9.2(a)(iii) of this Agreement directly against Contributor. In addition, in all circumstances, a Contributee Indemnified Party must first look to the Escrow Account with respect to an indemnity claim, including those arising under Section 9.2(a)(i) (for representations and warranties which survive longer than one (1) year after the Closing Date) and Section 9.2(a)(ii) of this Agreement, which are not limited to the Escrow Account. Contributee’s indemnification obligations under Section 9.2(b)(i) shall not exceed five percent (5%) of the Agreed Value.

     (c) The amount of any Losses subject to indemnification under this ARTICLE IX shall be reduced or reimbursed, as the case may be, by any third party insurance proceeds, third party recoveries less the costs expended for such recoveries. Each Party shall, and shall cause their respective Indemnified Parties to, use Reasonable Efforts to collect any amounts available under such insurance coverage and from such other third party alleged to have responsibility. If a Contributee Indemnified Party receives an amount under insurance coverage or from such third party with respect to Losses that were the subject of indemnification under Section 9.2 at any time subsequent to indemnification provided thereunder, then such Contributee Indemnified Party shall promptly reimburse Contributor.

          9.4 Procedures. Claims for indemnification under this Agreement shall be asserted and resolved as follows:

     (a) If any Person who or which is entitled to seek indemnification under Section 9.2 (an “Indemnified Party”) receives notice of the assertion or commencement of any claim asserted against an Indemnified Party by a third party (“Third Party Claim”)

in respect of any matter that is subject to indemnification under Section 9.2, the Indemnified Party shall promptly (i) notify the Party obligated to the Indemnified Party pursuant to Section 9.2 above, (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any), the Indemnified Party’s best estimate of the amount of Losses attributable to the Third Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is prejudiced by such delay or omission.

     (b) The Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim. If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third Party Claim (such election to be without prejudice to the right of the Indemnified Party to dispute whether such claim is an identifiable Loss under this ARTICLE IX), then the Indemnifying Party shall have the right to defend such Third Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying Party in accordance with this Section 9.4(b). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided that the Indemnifying Party shall not enter into any settlement agreement without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided further, that such consent shall not be required if (i) the settlement agreement contains a complete and unconditional general release by the third party asserting the claim to all Indemnified Parties affected by the claim and (ii) the settlement agreement does not contain any sanction or restriction upon the conduct of any business by the Indemnified Party or its Affiliates. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the Person asserting the Third Party Claim or any cross complaint against any Person. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 9.4(b), and the Indemnified Party shall bear its own costs and expenses with

respect to such participation.

     (c) If the Indemnifying Party does not notify the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 9.4(b), then the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable cost and expense (but only if the Indemnified Party is actually ultimately determined to be entitled to indemnification hereunder) in regard to the Third Party Claim with counsel selected by the Indemnified Party (who shall be reasonably satisfactory to the Indemnifying Party), by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such Third Party Claim in good faith and have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 9.4(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

     (d) Any claim by an Indemnified Party on account of Losses that does not result from a Third Party Claim (a “Direct Claim”) will be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) days after the Indemnified Party becomes aware of such Direct Claim. Such notice by the Indemnified Party will describe the Direct Claim in reasonable detail, will include copies of all available material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of damages that has been or may be sustained by the Indemnified Party. The Indemnifying Party will have a period of twenty (20) days within which to object or accept in writing such Direct Claim. Any such objection is called a “Notice of Claim Dispute.” If the Indemnifying Party does not so respond within such twenty (20) day period, the Indemnifying Party will be deemed to have rejected such claim, in which event the Indemnified Party will be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement. Copies of each Notice of Claim Dispute shall be sent to Contributee and the Escrow Agent. If Contributee and Contributor fail to resolve any objection contained in such Notice of Claim Dispute within twenty (20) days after the date the Notice of Claim Dispute is delivered to Contributee, then, at the request of either

Party, they shall meet in an attempt to resolve an objection described in such Notice of Claim Dispute and reach a written agreement with respect to such objection (a “Claim Settlement Agreement”). If Contributor and Contributee enter into a Claim Settlement Agreement, the objections contained in such Notice of Claim Dispute shall be deemed to be as resolved therein. If they are unable to resolve the objection described in such Notice of Claim Dispute within twenty (20) days after delivery to the recipient of such Notice of Claim Dispute, then Contributor and Contributee shall submit the objections contained in such Notice of Claim Dispute to arbitration as described in Section 9.5.

          9.5 Notice of Claim Dispute. Any objection contained in a Notice of Claim Dispute not resolved in a Claim Settlement Agreement shall be resolved by submission to arbitration as follows: Contributor and Contributee shall select a single arbitrator from the American Arbitration Association (“AAA”) in Houston, Texas (an “Arbitrator”) (or, if they cannot agree upon a selection, Contributor and Contributee shall each select an Arbitrator, and the two Arbitrators so selected shall choose a third Arbitrator who has knowledge of the industry and business of the Contributor and who shall act as the Arbitrator to resolve the dispute). The Arbitrator shall resolve the objection contained in the Notice of Claim Dispute pursuant to the Commercial Arbitration Rules of the AAA as promptly as possible and a decision by the Arbitrator as to the resolution of such objection (the “Arbitrator’s Decision”) shall be (absent an agreement of the parties regarding an error that is manifest) conclusive and binding upon the parties for purposes of this Agreement. The Arbitrator’s Decision shall be (i) in writing and (ii) non-appealable and incontestable by Contributee and Contributor and each of their respective Affiliates and successors and not subject to collateral attack for any reason. The Arbitrator shall have the ability to allocate fees and costs payable to the AAA based on the Arbitrator’s assessment of the relative responsibility of the parties. In the absence of such an allocations, the fees and costs payable to the AAA shall be paid one-half by Contributee and one-half from the Escrow Deposit. Contributee shall pay its own counsel fees and other costs incurred in connection with any such dispute, and counsel fees and other costs incurred by Contributor in connection with any such dispute shall be paid from the Escrow Deposit.

          9.6 Escrow Account. At the Closing, the Parties shall enter into the Escrow Agreement. Whether included in such agreement, the Parties agree that the following provisions of this Section 9.6 shall control with respect to the Escrow Account:

     (a) The Contributee Units and any income or cash in the Escrow Account shall be transferred by the Escrow Agent as follows:

     (i) to Contributee, pursuant to a Claim Settlement Agreement delivered to the Escrow Agent;

     (ii) to Contributee, pursuant to joint written instructions from Contributors and Contributee to the Escrow Agent relating to the resolution of a Third Party Claim pursuant to Section 9.4;

     (iii) to Contributee, pursuant to any other joint written instruction from Contributors and Contributee to the Escrow Agent;

     (iv) to Contributee, pursuant to a decision by the Arbitrator regarding a Direct Claim sent to the Escrow Agent pursuant to Section 9.5;

     (v) to Contributors, on the first anniversary of the Closing Date, in an amount equal to the remainder of the Escrow Deposit less any amounts related to an asserted but pending or unpaid Direct Claim or Third Party Claim.

     (b) Contributors shall have the right to vote any Contributee Units which are held in the Escrow Account.

          9.7 No Special, Consequential or Punitive Damages. NOTWITHSTANDING ANYTHING HEREIN CONTAINED TO THE CONTRARY, NONE OF THE PARTIES TO THIS AGREEMENT SHALL HAVE ANY OBLIGATION WITH RESPECT TO THIS AGREEMENT, OR OTHERWISE IN CONNECTION HEREWITH, FOR ANY SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES.

          9.8 Waiver of Other Representations. EXCEPT FOR AND WITHOUT ANY LIMITATION WHATSOEVER ON THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT OR IN ANY CERTIFICATE OR WRITTEN STATEMENT FURNISHED, OR TO BE FURNISHED TO CONTRIBUTEE PURSUANT TO THIS AGREEMENT OR IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY: (A) CONTRIBUTOR, NOR ANY OF ITS AFFILIATES OR REPRESENTATIVES, HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, AT LAW OR IN EQUITY, IN RESPECT OF EACH COMPANY, ITS BUSINESS OR ANY OF ITS ASSETS, LIABILITIES OR OPERATIONS, INCLUDING WITH RESPECT TO MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE, OR WITH RESPECT TO ANY FINANCIAL PROJECTIONS OR FORECASTS RELATING TO EACH COMPANY, AND ANY SUCH

OTHER REPRESENTATION AND WARRANTIES ARE HEREBY DISCLAIMED AND (B) CONTRIBUTOR MAKES NO WARRANTY OR REPRESENTATION, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, AS TO THE ACCURACY OR COMPLETENESS OF ANY DATA, REPORTS, RECORDS, PROJECTIONS, INFORMATION OR MATERIALS NOW, HERETOFORE OR HEREAFTER FURNISHED OR MADE AVAILABLE TO CONTRIBUTEE IN CONNECTION WITH THIS AGREEMENT INCLUDING, WITHOUT LIMITATION, RELATIVE TO 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 OR THE ENVIRONMENTAL CONDITION OF THE PROPERTIES OR ANY OTHER MATTERS CONTAINED IN ANY MATERIALS FURNISHED OR MADE AVAILABLE TO CONTRIBUTEE BY CONTRIBUTOR OR BY CONTRIBUTOR’S AGENTS OR REPRESENTATIVES (ANY AND ALL SUCH DATA, RECORDS, REPORTS, PROJECTIONS, INFORMATION AND OTHER MATERIALS (WRITTEN OR ORAL) FURNISHED BY CONTRIBUTOR OR OTHERWISE MADE AVAILABLE OR DISCLOSED TO CONTRIBUTEE ARE PROVIDED TO CONTRIBUTEE AS A CONVENIENCE AND SHALL NOT CREATE OR GIVE RISE TO ANY LIABILITY OF OR AGAINST CONTRIBUTOR AND ANY RELIANCE ON OR USE OF THE SAME SHALL BE AT CONTRIBUTEE’S SOLE RISK TO THE MAXIMUM EXTENT PERMITTED BY LAW).

          9.9 Exclusive Remedy and Release. Except as otherwise provided herein, the indemnification and remedies set forth in this ARTICLE IX shall, from and after the Closing, constitute the sole and exclusive remedies of the Parties with respect to any breach of representation or warranty contained in this Agreement; provided that nothing in this Section 9.9 shall prevent either Party from seeking injunctive or equitable relief in pursuit of its indemnification claims under this ARTICLE IX.

ARTICLE X

     (a) by the mutual consent of Contributee and Contributor as evidenced in writing signed by each of Contributee and Contributor;

     (b) by Contributee, if there has been a material breach by Contributor of any representation, warranty or covenant contained in this Agreement that has prevented the satisfaction of any condition to the obligations of Contributee at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by Contributor within ten (10) Business Days after written notice thereof from Contributee;

     (c) by Contributor if there has been a material breach by Contributee of any representation, warranty or covenant contained in this Agreement that has prevented the satisfaction of any condition to the obligations of Contributor at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by Contributee within ten (10) Business Days after written notice thereof from Contributor;

     (d) by either Contributee or Contributor if any Governmental Authority having competent jurisdiction has issued a final, non-appealable order, decree, ruling or injunction (other than a temporary restraining order) or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement;

     (e) by either Contributee or Contributor, if the transactions contemplated hereby have not been consummated by August 15, 2007, provided that neither Contributee nor Contributor will be entitled to terminate this Agreement pursuant to this Section 10.1(e) if such Person’s breach of this Agreement has prevented the consummation of the transactions contemplated by this Agreement.

          10.2 Effect of Termination. If this Agreement is terminated under Section 10.1, all further obligations of the Parties under this Agreement will terminate without further liability or obligation of either Party to the other Parties hereunder; provided, however, that no Party will be released from liability hereunder if this Agreement is terminated and the transactions abandoned by reason of (a) failure of such Party to have performed its material obligations under this Agreement or (b) any material misrepresentation made by such Party of any matter set forth in this Agreement. Nothing in this Section 10.2 will relieve any Party to this Agreement of liability for breach of this Agreement occurring prior to any termination, or for breach of any provision of this Agreement that specifically survives termination hereunder.
