          (a) As soon as reasonably practicable following the date of this Agreement, and in no event later than sixty (60) days from the date hereof, Buyer shall deliver to Seller written notices identifying each matter that it believes in good faith to be a Title Defect, together with a good faith estimate of the associated cost of curing such defect (the “Title Defect Amount”) for each such alleged Title Defect, and reasonable written documentation, to support

Buyer’s claims of each such Title Defect (the “Title Defect Notice”); it being understood that neither the delivery nor cure or resolution of such Title Defect Notice shall be a condition to the occurrence of the Closing. In order for Seller to review the alleged Title Defects listed in the Title Defect Notice, Buyer will provide to Seller and its representatives copies of any documents used to determine the existence of a Title Defect and the estimated cost to cure any Title Defect. Buyer shall include in the Title Defect Notice only Title Defects that are reasonably believed, in good faith, to individually cost in excess of $25,000 to cure. For purposes of calculating the cost of a Title Defect, the Parties shall value (i) rights-of-way at $25 per rod and (ii) surface leases and fee properties at fair market value.

          (b) If Seller disagrees with the existence of a Title Defect or the associated Title Defect Amount, then Seller shall notify Buyer of such disagreement in writing (a “Notice of Disagreement”) within thirty (30) days after its receipt of the applicable Title Defect Notice, it being understood that neither the delivery nor cure or resolution of such Notice of Disagreement shall be a condition to the occurrence of the Closing. Such Notice of Disagreement shall specify in reasonable detail Seller’s grounds for such disagreement, the Title Defect Amount estimated by Seller therefor, or both, as the case may be. To the extent Seller does not contest a Title Defect or a Title Defect Amount in a Notice of Disagreement within the time period specified in this Section 2.7(b), Seller shall be deemed to have accepted the existence of such Title Defect or Title Defect Amount, which shall be final, binding and conclusive for all purposes hereunder.

          (c) If a Notice of Disagreement is timely provided by Seller, Buyer and Seller shall use commercially reasonable efforts for a period of thirty (30) days after delivery of such Notice of Disagreement (or such longer period as they may mutually agree) to resolve any disagreements with respect to the existence of any Title Defect or Title Defect Amount contested in the Notice of Disagreement. If, at the end of such period, they are unable to resolve such disagreements, then, upon the written request of either Party, Seller and Buyer agree that within a further fifteen (15) day period, they will jointly select an arbitrator who is an attorney experienced in the natural gas and gas gathering industry in the United States as well as in real estate and title insurance matters, or as otherwise mutually agreed upon by Seller and Buyer (the “Title Defect Arbitrator”), to resolve any remaining disagreements. If Seller and Buyer are unable to agree upon the designation of a Person as a Title Defect Arbitrator, they shall request the American Arbitration Association to appoint the Title Defect Arbitrator and such Title Defect Arbitrator shall hear all matters submitted under this Section 2.7(c).

          (d) The Title Defect Arbitrator shall determine as promptly as practicable (but in any event within thirty (30) days following the date on which such dispute is referred to the Title Defect Arbitrator) the existence of any alleged Title Defect or the disputed Title Defect Amount, as the case may require, identified in the Notice of Disagreement and not previously resolved by the Parties. Each Party shall set forth in writing its position regarding the existence of each alleged Title Defect and each Title Defect Amount referred to the Title Defect Arbitrator for resolution, and the Title Defect Arbitrator shall be required to select the position of either one Party or the other with respect to each such Title Defect or Title Defect Amount, as the case may require. Each Party shall bear its own expenses and the fees and expenses of its own representatives and experts in connection with the preparation, review, dispute (if any) and final determination of any alleged Title Defects. Buyer, on the one hand, and Seller, on the other hand, shall share equally the costs, expenses and fees of the Title Defect Arbitrator. The

determination of the Title Defect Arbitrator shall be final, conclusive and binding on the Parties and shall be enforceable in any court having jurisdiction.

          (e) As used in this Agreement, an “Agreed-Upon Title Defect” shall mean any of (i) a Title Defect that is not contested under any Notice of Disagreement timely given, (ii) a Title Defect that is mutually agreed upon by Buyer and Seller or (iii) a Title Defect resulting from a determination of the Title Defect Arbitrator pursuant to Section 2.7(d) above. The date on which any Title Defect becomes an Agreed-Upon Title Defect pursuant to the foregoing is referred to as the “Title Defect Determination Date.” An “Agreed-Upon Title Defect Amount” shall mean any of (i) a Title Defect Amount that is not contested under any Notice of Disagreement timely given, (ii) a Title Defect Amount that is mutually agreed upon by Buyer and Seller or (iii) a Title Defect Amount resulting from a determination of the Title Defect Arbitrator pursuant to Section 2.7(d) above.

          (f) At Closing the Purchased Assets Sale Price shall be reduced by the aggregate amount of any Agreed-Upon Title Defect Amount finalized by Closing. After Closing, the Seller shall promptly pay to Buyer any Agreed-Upon Title Defect Amount finalized after Closing. Buyer understands and agrees that the Purchased Assets Sale Price adjustment provided in this Section 2.7 is the sole and exclusive remedy for a Title Defect, and no claim may be made by Buyer with respect to any representation or warranty made by Seller or any of its affiliates or representatives. Notwithstanding the provisions of this Section 2.7, the Purchased Assets Sale Price shall not be decreased by any Agreed-Upon Title Defect Amount unless and until the aggregate Agreed-Upon Title Defect Amount exceeds $100,000, then only to the extent of such excess, and the maximum decrease of the Purchased Assets Sale Price pursuant to this Section 2.7 for all Title Defects shall not exceed $1,000,000.

If the Parties fail to obtain any authorization, consent, approval or waiver (including those listed on Seller Parties’ Schedule 3.3(b), Seller Parties’ Schedule 3.3(e), Buyer’s Schedule 4.3(b) and Buyer’s Schedule 4.3(d)) needed for the consummation of the transactions contemplated by this Agreement and the other Transaction Documents, or if any such consent, approval or waiver is otherwise not in full force and effect as of the Closing, then, in the case of each Assumed Contract as to which such consent, approval or waiver was not obtained (or otherwise is not in full force and effect) (the “Non-Consent

Contracts”), notwithstanding anything to the contrary in this Agreement, neither this Agreement, nor any of the other Transaction Documents, nor any other document related to the consummation of the transactions contemplated hereby shall constitute a sale, assignment, assumption, transfer, conveyance or delivery or an attempted sale, assignment, assumption, transfer, conveyance or delivery of the Non-Consent Contracts, and, following the Closing, the Parties shall cooperate with each other to obtain the consent, approval or waiver relating to each Non-Consent Contract. Pending the obtaining of such consent, approval or waiver relating to any Non-Consent Contract, the Parties shall cooperate with each other in any reasonable and lawful arrangements designed to provide to Buyer the benefits and burdens of use of each Non-Consent Contract for its term (or any right, benefit, obligation or duty arising thereunder, including the enforcement for the benefit of Buyer of any and all rights of the Seller Parties or their Affiliates against any Person thereunder). After the consent, approval or waiver for the sale, assignment, assumption, transfer, conveyance and delivery of a Non-Consent Contract is obtained, the Seller Parties shall promptly assign, transfer, convey and deliver such Non-Consent Contract to Buyer, and Buyer shall assume the obligations under such Non-Consent Contract assigned to Buyer from and after the date of assignment to Buyer pursuant to a separate assignment and assumption agreement substantially similar in terms to those of the Assignment and Assumption Agreement (which separate agreement the parties shall prepare, execute and deliver in good faith at the time of such transfer, all at no additional cost to Buyer).

     5.6 Preferential Rights and Third Party Consents. Seller will, and Gasco will cause Seller to, request, from the appropriate parties (and in accordance with the documents creating such rights and/or requirements), waivers of any preferential rights to purchase or other requirements of consent to assignment. Seller shall have no obligation hereunder other than to so request waivers, and if any such waiver is not obtained, Buyer may treat any waiver with respect to Real Property Interests which is not obtained as a Title Defect; provided that if the unobtained waiver is a waiver of a preferential right to purchase and such necessary waiver of the preferential right is obtained or the period to exercise such right expires before the Closing Date, such waiver shall not be considered a Title Defect.

     5.7 Casualty Loss. If, after the date hereof and prior to the Closing Date, all or any part of the Assets shall be damaged or destroyed by explosion, fire or other casualty (“Casualty Losses”), and if the Closing occurs, each of the Seller Parties shall pay to Buyer all sums paid to such Seller Party by third parties (including under any insurance policies) by reason of such Casualty Loss, and such Seller Party shall assign, transfer and set over unto Buyer all of the right, title and interest of such Seller Party in and to any unpaid awards or other payments from third parties (including under any insurance policies) arising out of such Casualty Loss, in all cases less (i) any amounts received by such Seller Party under business interruption insurance policies with respect to all periods on or prior to the Closing Date and (ii) any amount incurred by Seller to restore the affected property or protect it against further damage or loss. Seller shall, and Gasco shall cause Seller to, also pay to Buyer upon receipt all sums paid to Seller by third parties (including under any insurance policies) with respect to business interruption for all periods after the Closing Date. Seller shall, and Gasco shall cause Seller to, indemnify and hold harmless Buyer to the extent provided in Section 7.2(a) against any Casualty Losses not paid or otherwise reimbursed to Buyer pursuant to this Section 5.7. Seller shall not, and Gasco shall cause Seller not to, voluntarily compromise, settle or adjust any amounts payable with respect to

insurance relating to such Casualty Loss without the prior written consent of Buyer, which shall not be unreasonably withheld, delayed or conditioned.

     5.8 Seller Marks. Buyer shall obtain no right, title, interest, license or any other right whatsoever to use the term “Gasco” or any trademarks, service marks, slogans or logos containing or comprising the foregoing, or any trademark, service mark, slogan or logo confusingly similar thereto or dilutive thereof (collectively, the “Seller Marks”). From and after the Closing, Buyer agrees that it shall (a) cease using the Seller Marks in any manner, directly or indirectly, except for such limited uses as cannot be terminated within a reasonable time period (e.g., signage, e-mail addresses, and as a referral or pointer to the acquired website), and to cease such limited usage of the Seller Marks and (b) remove, strike over or otherwise obliterate all Seller Marks from all Assets, in each case within a reasonable time period after the Closing and in any event within one hundred-twenty (120) days following the Closing Date. The Parties agree, because damages would be an inadequate remedy, that a Party seeking to enforce this Section 5.8 shall be entitled to seek specific performance and injunctive relief as remedies for any breach thereof in addition to other remedies available at law or in equity. This covenant shall survive indefinitely without limitation as to time.

     5.9 Riverbend Marks. Promptly after the Closing, each of the Seller Parties shall (a) cease using the Riverbend Marks in any manner, directly or indirectly except for such limited uses as cannot be terminated within a reasonable time period, and to cease such limited usage of the Riverbend Marks within a reasonable time period after the Closing and in any event within one hundred-twenty (120) days following the Closing Date and (b) take all necessary actions to change the corporate name of such Seller Party so that it does not contain the Riverbend Marks or any term confusingly similar thereto. The Parties agree, because damages would be an inadequate remedy, that the Buyer shall be entitled to seek specific performance and injunctive relief as remedies for any breach of this Section 5.9 in addition to other remedies available at law or in equity. This covenant shall survive indefinitely without limitation as to time.

     5.10 Records. Each of the Parties shall preserve and keep a copy of all records relating to the Gathering System or the Assets (including the Transferred Records) in its possession for a period of at least seven (7) years after the Closing Date. After such seven-year period, before any Party shall dispose of any such records, such Party shall give the other Parties at least ninety (90) days’ prior notice to such effect, and each of the other Parties shall be given an opportunity, at its cost and expense, to remove and retain all or any part of such records as it may select. Each of the Parties shall provide to the other, at no cost or expense to the other, full access to such records as remain in such Party’s possession and full access to its properties and employees in connection with matters relating to the Assets on or before the Closing and any disputes relating to this Agreement.

     5.11 Transferred Permits. Buyer shall use Reasonable Efforts to provide all notices and otherwise take all actions required to transfer or reissue any Transferred Permits as a result of or in furtherance of the transactions contemplated by this Agreement and the other Transaction Documents. Buyer shall reasonably promptly provide Seller with copies of all such filings when made. Seller shall, and Gasco shall cause Seller to, use Reasonable Efforts to cooperate with Buyer to provide information necessary to achieve the transfer or reissue of such Transferred Permits.

     5.12 Guarantees. Buyer acknowledges the list of Guarantees set forth on Seller Parties’ Schedule 3.22 and agrees in the case of any such Guarantee that it shall use Reasonable Efforts to cooperate with the Seller Parties in order to (i) to terminate any such Guarantee (including offering to substitute a guarantee of Buyer or one of its Affiliates or Subsidiaries for such Guarantee) and (ii) procure from the existing obligee the release of the Seller Party that is a party to such Guarantee from any and all Liability from and under such Guarantee accruing after the Closing Date (if the Salt Water Disposal Assets are transferred at the Closing) or the date of the Salt Water Disposal Assets Closing (if the Salt Water Disposal Assets are not transferred at the Closing) (as applicable, the “Target Release Date”), which release shall be acceptable to the existing obligee and shall take effect at and as of the Target Release Date. To the extent that the Seller Party is not able to terminate any such Guarantee and obtain any such release prior to the Target Release Date in accordance with clause (ii) of the preceding sentence, Buyer agrees that it shall (a) continue to use Reasonable Efforts thereafter to effect such a termination and release and (b) defend, indemnify and hold harmless the Seller Parties of, from and against any Damages that such Seller Party may incur or suffer as a result of being required to perform any obligations under, or against any claim made or threatened to be made in connection with, any such Guarantees to the extent relating to actions first occurring or conditions first existing from and after the Target Release Date. This indemnification shall be in addition to the indemnification provided pursuant to ARTICLE VII and shall not be subject to the thresholds, Deductible or other limitations on amount set forth therein; provided that in no event shall Buyer be required to defend, indemnify and hold harmless the Seller Parties for any such Damages to the extent the Seller Parties are required to indemnify the Buyer Parties for such Damages pursuant to Section 7.2.

     5.13 Employees. Seller Parties’ Schedule 5.13(a) lists all employees of Seller Parties that have worked on the operations of the Gathering System as their principal job duty in the preceding 12 months.

          (b) Only those Employees listed on Seller Parties’ Schedule 3.20(a) are available for hire by Buyer. Any employment offers to any of the Employees shall be under the terms that Buyer, in its sole discretion, determines. Nothing herein shall require Buyer to offer employment to any particular Employee or to offer any specific terms of employment to any Employee.

          (c) No earlier than the Effective Date and no later than five (5) days before the termination date of the Transition Services Agreement (the “Transition Period”), Buyer shall make an offer of employment to those Employees that it wishes to hire; provided that, not later than two (2) days before the termination date of the Transition Services Agreement, Buyer shall inform Seller in writing of the names of those Employees to whom it has made offers and the terms of such offers. On the date that Buyer selects for such employee to be hired (the “Start Date”), which date shall not be earlier than the Closing Date, Gasco shall terminate or cause to be terminated the employment of each Employee who accepts Buyer’s offer of employment (each, a “Transferred Employee”), such termination to be effective as of the Start Date. From and after the Effective Date until the earlier to occur of his or her respective Start Date or the expiration of the Transition Period, each Transferred Employee shall continue to be an employee of Seller or its Affiliates and participate in the Employee Benefit Plans. As of the termination date of the Transition Services Agreement, all Transferred Employees shall be entitled to

participate in the benefit plans and arrangements sponsored by Buyer, subject to the terms and conditions of such benefit plans and arrangements. The Seller Parties shall waive enforcement of any and all non-compete, confidential information and restrictive covenants or agreements applicable to each such Transferred Employee, so that any such Transferred Employee will not be in violation of any such obligations to the Seller Parties when such Transferred Employee is employed by Buyer or by any Affiliate or Subsidiary of Buyer.

          (d) Prior to the Closing, the Seller Parties shall comply (and shall cause all of their Affiliates and Subsidiaries to comply) with all applicable Laws in connection with the termination of employment of any Transferred Employee, and Gasco shall retain all liability relating to the employment of each Transferred Employee to the extent arising prior to his or her Start Date, it being understood that Buyer or its Affiliates, as applicable, shall assume all liability relating to the employment of each Transferred Employee arising on or after their respective Start Dates.

          (e) Gasco or the insurer of the Seller Parties’ welfare plans shall be responsible for all claims for welfare benefits (“Welfare Benefit Claim”) with respect to all Transferred Employees (and their covered dependents and beneficiaries) that arose prior to their respective date of hiring. Any Welfare Benefit Claims incurred by any Transferred Employee on or after the date of hiring shall be Buyer’s responsibility in accordance with the terms of any applicable welfare benefit plan maintained by Buyer for the Transferred Employees. A Welfare Benefit Claim shall be deemed to have arisen when the services relating to the condition that is the subject of the claim are performed.

          (f) Gasco waives (and shall cause all Affiliates and Subsidiaries of Gasco to waive) any and all claims against Buyer and the Transferred Employees arising from any Transferred Employee’s employment by Buyer, to the extent such claims arise under any employment agreement, confidentiality or non-disclosure agreement or policy, or non-competition agreement between any such Transferred Employee and Gasco (or any Affiliate or Subsidiary of Gasco).

          (g) As of the termination date of the Transition Services Agreement, to the extent any of the Available Employees become Transferred Employees, Buyer shall assume liability for the Seller Parties’ obligations under COBRA, including the obligation, if any, to provide notice and continuation of coverage to any Transferred Employee who is a covered employee or qualified beneficiary (as such terms are defined in section 4980(f) of the Code) or has a qualifying event (as defined in Section 4980(f) of the Code) incident to the transactions contemplated by this Agreement.

          (h) Buyer will not assume any Employee Benefit Plan or any Liabilities thereunder, and none shall be considered an acquired “Asset,” an “Assumed Contract,” or an “Assumed Liability” for purposes of this Agreement.

          (i) FUTA; FICA. Subject to Buyer determining in good faith that it is legally permitted to do so, Gasco and Buyer shall treat Buyer as a “successor employer” and each Seller as a “predecessor” within the meaning of Sections 3121(a)(1) and 3306(b)(1) of the Code with respect to Transferred Employees for purposes of Taxes imposed under the United States Federal

Unemployment Tax Act (“FUTA”) or the United States Federal Insurance Contributions Act (“FICA”).

     5.14 Insurance. Buyer hereby acknowledges that on and as of the Closing Date, Buyer shall be responsible for obtaining and maintaining insurance covering the Assets and that, subject to Section 3.14, on and as of the Closing Date, the Seller Parties shall not be responsible for the maintenance of any insurance policy relating to the Assets.

     5.15 Liability for Transfer Taxes. Any state or local transfer, sales, use, stamp, registration or other similar Taxes resulting from or that are imposed as a result of the transactions contemplated by this Agreement shall be borne equally by Seller and Buyer. Buyer and Seller Parties, as appropriate, shall file, to the extent required by applicable Laws, all necessary Tax Returns and other documentation with respect to such Taxes, and, if required by applicable Laws, Buyer and/or Seller Parties, as appropriate, will join in the execution of any such Tax Return or other documentation of the other.

     5.16 Cooperation on Tax Matters.

          (a) In connection with the preparation of Tax Returns directly related to the Assets, audit examinations directly related to the Assets, and any administrative or judicial proceedings regarding Tax Liabilities that are imposed on the Seller Parties or Buyer and directly relate to the Assets, Buyer and the Seller Parties shall cooperate fully with each other, including with respect to the furnishing or making available during normal business hours of records, personnel (as reasonably required), books of account, powers of attorney or other materials necessary or helpful for the preparation of such Tax Returns, the conduct of such audit examinations or the defense of claims by Governmental Authorities as to the imposition of such Taxes.

          (b) For purposes of determining Retained Liabilities and Assumed Liabilities, (i) all ad valorem taxes, real property taxes, personal property taxes and similar obligations (“Property Taxes”) attributable to the Assets with respect to a tax period in which the Closing Date occurs shall be apportioned between the period ending on the Closing Date and the period from and after the Closing Date by prorating such Property Taxes on a daily basis over the entire tax period, and (ii) all taxes that are based upon or related to income or receipts attributable to the Assets with respect to a tax period in which the Closing Date occurs shall be apportioned based on an interim closing of the books as of the Closing Date with the Seller Parties being allocated the amount that would be payable if the taxable year of the Seller Parties ended with (and included) the Closing Date; provided that exemptions, allowance or deduction that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the period ending on the Closing Date and the period from and after the Closing Date in proportion to the number of days in each period.

     5.17 Use of Proceeds. Promptly after the Closing, Gasco shall (x) use $15 million of the proceeds from the sale of the Assets to repay outstanding Indebtedness for money borrowed of Gasco and its Subsidiaries and (y) obtain the consent to such payment of those lenders holding a first lien on the Assets.

     5.18 Environmental Matters.

          (a) Buyer acknowledges that Gasco and the Gathering System are the subject of the EPA Enforcement Action brought by the United States Department of Justice (“DOJ”) on behalf of the United States Environmental Protection Agency (“EPA”) that is more particularly described on Seller Parties’ Schedule 3.12. Gasco has been negotiating and continues to negotiate a consent decree to resolve the EPA Enforcement Action (“EPA Consent Decree”), but Gasco believes that the EPA Consent Decree will not have been finalized or entered before the Closing Date. The most recent draft of the EPA Consent Decree provided by Seller to Buyer (“EPA Consent Decree Draft”) is attached hereto as Exhibit G-1. The Parties shall cooperate to attempt to negotiate with DOJ and EPA a final EPA Consent Decree that (i) does not impose upon Buyer or the Assets any costs or obligations that are in addition to or more stringent than those included in the EPA Consent Decree Draft as amended in accordance with Buyer’s comments attached hereto as Exhibit G-2 (the “Buyer Mark-up of the EPA Consent Decree Draft”); and (ii) is otherwise satisfactory in form and substance to Buyer.

          (b) Following the date hereof, Buyer and its representatives shall have the right to participate fully in all discussions and negotiations with the DOJ and EPA with regard to the resolution of the EPA Enforcement Action, including in connection with the drafting and negotiation of the EPA Consent Decree. In conjunction therewith, the Seller Parties shall at all times (i) keep Buyer reasonably informed relating to discussions or negotiations with DOJ and EPA and notify Buyer of, and give Buyer an opportunity to attend, scheduled voice or in-person conferences with DOJ, EPA and any other third party (other than consultants or counsel retained by the Seller Parties) relating to the EPA Enforcement Action or EPA Consent Decree; (ii) provide Buyer with a reasonable period of time, given the specific circumstances, to permit it to comment on any drafts of the EPA Consent Decree; and (iii) timely provide copies of any reports, correspondence and other documentation received from DOJ, EPA or any other third party or consultants retained by the Seller Parties relating to the EPA Enforcement Action or EPA Consent Decree.

          (c) The Seller Parties will, concurrently with negotiating the EPA Consent Decree, work diligently and promptly from the date hereof until the Closing Date to complete and pay for all actions or projects required by the EPA Consent Decree Draft or otherwise necessary to resolve completely all issues raised by the EPA Enforcement Action other than installation of pneumatic controls as set forth on Schedule 5.18(c). The Seller Parties will provide to Buyer written documentation and other evidence reasonably requested by Buyer as soon as reasonably practicable, but no later than the Closing Date, demonstrating to the reasonable satisfaction of Buyer that the actions and projects required by this clause (c) have been completed.

          (d) The Seller Parties will work diligently and promptly to complete and pay for all actions or projects, including all Remedial Actions, (i) necessary to ensure that (x) Spill Prevention, Control and Countermeasure Plans (“SPCC Plans”) and Spill Contingency Plans (“Contingency Plans”) have been prepared for all Assets required to have such SPCC Plans and Contingency Plans under any Environmental Law and (y) all SPCC Plans and Contingency Plans maintained or required to be maintained by the Seller Parties in connection with the Assets are accurate and complete and meet all requirements under Environmental Laws; and (ii) necessary

to identify the source, content and scope of the staining and standing fluids at the Questar Tap and Gate Canyon Compressor Station and to fully address such matters, including undertaking and completing all Remedial Action to address any affected soil, surface water and groundwater, in each case to the reasonable satisfaction of Buyer and in compliance with the terms of all Environmental Laws and the requirements of any Governmental Authorities, and to promptly and properly repair, upgrade or replace any processes, equipment or facilities at the Questar Tap or Gate Canyon Compressor Station that are causing or contributing to such staining or standing fluids. The Seller Parties will provide to Buyer written documentation and other evidence reasonably requested by Buyer as soon as reasonably practicable and, with respect to clause (i) above, no later than the Closing Date, demonstrating to the reasonable satisfaction of Buyer that the actions and projects required by this clause (d) have been completed.

     5.19 Noncompetition. (a) Each of the Seller Parties agrees that until December 31, 2014, neither it nor any of its Affiliates, excluding (i) the executive officers of Gasco and its subsidiaries that cease to be employed by Gasco or any of its subsidiaries and (ii) the directors of Gasco, shall:

          (i) engage, either directly or indirectly, as a principal or for its own account or solely or jointly with others, or as stockholders in any corporation or joint stock association, in any business that competes with the Gathering System or the Salt Water Disposal Assets as they exist on the Closing Date within the counties of Carbon, Dagget, Duchesne, Grand, Summit, Uintah and Wasatch in the State of Utah and the counties of Garfield, Moffat and Rio Blanco in the State of Colorado; provided that nothing in this Section 5.19 shall prohibit the directors of Gasco from having beneficial ownership of the issued and outstanding Marketable Securities of any entity engaged in the energy industry generally; or

          (ii) solicit the performance of services by, any Transferred Employee;

          (iii) provided however, that for purposes of this Section, production-related activities carried out by any of the Seller Parties, including drilling and closing wells, entering and exiting easements and leaseholds, engaging in preliminary field gathering to enable delivery of gas to the Gathering System pursuant to the terms of the Gathering Agreement, and otherwise engaging in the actions and responsibilities authorized or required pursuant to the Gathering Agreement, the Salt Water Disposal Services Agreement or any of the Seller Parties’ joint operating agreements, Unit Operating Agreements and Gas Balancing Agreements (solely to the extent that such actions and responsibilities pursuant to Seller Parties’ joint operating agreements, Unit Operating Agreements and Gas Balancing Agreements do not involve natural gas gathering or processing or the collection, disposal or recycling of salt water) are deemed by the Parties to be business that does not compete with the Gathering System.

          (b) If any provision contained in this Section shall for any reason be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Section, but this Section shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. It is the intention of the Parties that if any of the restrictions or covenants contained herein is held to cover a

geographic area or to be for a length of time which is not permitted by applicable Law, or in any way construed to be too broad or to any extent invalid, such provision shall not be construed to be null, void and of no effect, but to the extent such provision would be valid or enforceable under applicable Law, a court of competent jurisdiction shall construe and interpret or reform this Section to provide for a covenant having the maximum enforceable geographic area, time period and other provisions (not greater than those contained herein) as shall be valid and enforceable under such applicable Law. Each of the Seller Parties acknowledges that Buyer would be irreparably harmed by any breach of this Section and that there would be no adequate remedy at law or in damages to compensate Buyer for any such breach. Each of the Seller Parties agrees that Buyer shall be entitled to injunctive relief requiring specific performance by each of the Seller Parties of this Section, and each of the Seller Parties consents to the entry thereof.

     5.20 Further Assurances. Each Party hereto will, notwithstanding the existence of a Title Defect Notice or Notice of Disagreement, make Reasonable Efforts as are necessary or desirable and execute any additional documents, instruments or conveyances of any kind which may be reasonably necessary to further effect the transactions contemplated by this Agreement and the other Transaction Documents; provided, however, that no such action, document, instrument or conveyance shall increase a Party’s liability beyond that contemplated by this Agreement.

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

          (a) If any Person entitled to seek indemnification under Section 7.2 and Section 7.3 (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 7.2 or Section 7.3 the Indemnified Party shall promptly (i) notify the party against whom indemnification is sought (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 good faith estimate of the amount of Damages 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 materially prejudiced by such failure.

          (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, 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 7.4(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 contemplates only the payment of monetary damages by the Indemnifying Party or its Affiliates. Subject to the foregoing, if requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to use Reasonable Efforts 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 7.4(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 7.4(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 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). If requested by the Indemnified Party, the Indemnifying Party agrees, at the sole cost and expense of the Indemnifying Party, to use Reasonable Efforts to cooperate with the Indemnified Party and its counsel in contesting any Third Party Claim which the Indemnified 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

Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 7.4(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 Damages that does not result from a Third Party Claim (a “Direct Claim”) must be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than forty-five (45) days after an officer of the Indemnified Party becomes aware of such Direct Claim. Such notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, include copies of all available material written evidence thereof and indicate the estimated amount, if reasonably practicable, of Damages that have been or may be sustained by the Indemnified Party. The Indemnifying Party will have a period of twenty (20) Business Days within which to respond in writing to such Direct Claim. If the Indemnifying Party does not so respond within such twenty (20) Business 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.

          (e) Any indemnification payment made pursuant to this Agreement shall be net of (i) any insurance proceeds actually realized by and paid to the Indemnified Party in respect of such claim and (ii) any indemnification or reimbursement payments actually received or recovered, if recoverable, by the Indemnified Party from third parties with respect to such Damages. The amount of any Damages shall take into account any net Tax benefits attributable to the circumstance or event giving rise to such Damages and any Tax costs attributable to the receipt of indemnity payments hereunder. The Indemnified Party shall use Reasonable Efforts to collect any amounts to which they may be entitled under insurance policies or from third parties (pursuant to indemnification arrangements or otherwise) with respect to such Damages.

          (f) Except with respect to the EPA Enforcement Action, no Indemnified Party shall be entitled to bring a claim for indemnification for any breach or inaccuracy of any representation, warranty or covenant if such Indemnified Party had Knowledge of such breach or inaccuracy as of the Effective Date or if the facts or circumstances underlying such breach or inaccuracy are disclosed in the Disclosure Schedules.

          (g) Any Indemnified Party that becomes aware of Damages for which it seeks indemnification under this ARTICLE VII shall be required to use Reasonable Efforts to mitigate the Damages, including taking any actions reasonably requested by, and at the expense of, the Indemnifying Party, and the Indemnified Party shall not have any right to indemnification for any Damages to the extent that it is attributable to any Indemnified Party’s failure to use Reasonable Efforts to mitigate. The Indemnified Party shall not have any right to indemnification under this ARTICLE VII with respect to Damages to the extent that the Damages were materially and directly exacerbated by any action taken by any Indemnified Party for the first time on or after the Closing.

     7.5 Exclusive Remedy and Release. The Parties hereby acknowledge and agree that, other than with respect to (i) Title Defects, the sole and exclusive remedy for which is set forth in Section 2.7 hereof, and (ii) claims for actual fraud (as distinguished from constructive fraud) by the other Party or Parties, the indemnification provisions and remedies set forth in this ARTICLE

VII shall, from and after the Closing, constitute the sole and exclusive remedies of the Parties with respect to this Agreement and the transactions contemplated hereby and the Parties acknowledge and agree that the remedies available in this ARTICLE VII supersede any other remedies available at law or in equity.

ARTICLE VIII

     8.1 Termination. At any time prior to the Closing, this Agreement may be terminated and the transactions contemplated hereby abandoned:

          (a) by the mutual consent of Buyer and Seller as evidenced in a writing signed by each of Buyer and the Seller Parties;

          (b) by Buyer, if there has been a material breach of any representation, warranty or covenant of the Seller Parties contained in this Agreement that has prevented the satisfaction of any condition to the obligations of Buyer 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 the Seller Parties within thirty (30) days after written notice thereof from Buyer;

          (c) by Seller, if there has been a material breach of any representation, warranty or covenant of Buyer contained in this Agreement that has prevented the satisfaction of any condition to the obligations of the Seller Parties 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 Buyer within thirty (30) days after written notice thereof from Seller;

          (e) by either Buyer or Seller if the Closing shall not have been consummated on or before March 1, 2010; provided that the right to terminate this Agreement under this Section 8.1(e) shall not be available to a Party if its willful act or willful failure to act or whose Affiliate’s willful act or willful failure to act has been the principal cause of or resulted in the failure of the Closing to occur on or before such date.

     8.2 Effect of Termination. If this Agreement is terminated under Section 8.1, all further obligations of the Parties under this Agreement will terminate without further liability or obligation of any Party to the other Parties hereunder; provided, however, that no Party will be released from liability for any willful and intentional breach of this Agreement. Nothing in this Section 8.2 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. The provisions of ARTICLE IX shall survive any termination hereof pursuant to Section 8.1. The Confidentiality Agreement shall not be affected by a termination of this Agreement.

The failure of either Party to perform its obligations hereunder shall not release the other Party from the performance of such obligations.

     9.13 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties to the greatest extent legally permissible in order that the transactions contemplated herein are consummated as originally contemplated to the fullest extent possible.

     9.14 Governing Law; Jurisdiction.

          (a) This Agreement, the other Transaction Documents, and any claim, controversy or dispute arising under or related to this Agreement or the other Transaction Documents, the transactions contemplated hereby or thereby or the rights, duties and relationship of the parties hereto and thereto, shall be governed by and construed and enforced in accordance with the laws of the State of Delaware, except to the extent that the laws of the State of Utah are mandatorily applicable to the nature of any property interests and any conveyances of property interests involving real property located in the State of Utah.

     9.15 Arbitration.

          (a) Agreement to Arbitrate. Any and all claims, counterclaims, demands, causes of action, disputes, controversies and other matters in question arising out of or relating to this Agreement, or the alleged breach hereof, or in any way relating to the subject matter of this Agreement, or the relationship between the Parties created by this Agreement, except for any action by Buyer to seek specific performance pursuant to Section 5.19(b), which action shall be brought in the United States District Court for the District of Delaware or any Delaware State court sitting in Wilmington, Delaware, (each a “Dispute”), shall be finally resolved by binding arbitration administered by the American Arbitration Association (“AAA”) under the AAA Commercial Rules (the “Rules”) then in force, to the extent such Rules are not inconsistent with the provisions of this Agreement, regardless of whether some or all of such Disputes allegedly are (a) extra-contractual in nature; (b) sound in contract, tort, or otherwise; are provided by federal or state statute, common law or otherwise; or (d) seek damages or any other relief whether in law, in equity, or otherwise.

          (b) Venue, Procedural Issues. The seat of this arbitration shall be in Wilmington, Delaware. The hearings in this Arbitration shall be held at the seat or at such other place as the Parties may agree. The Parties agree that the United States Arbitration Act, Title 9, United States Code, as modified by this Agreement, shall govern procedural aspects of the arbitration.

          (c) Powers of the Arbitrators, Limitations on Remedies. The making, validity, construction, and interpretation of this agreement to arbitrate, and all procedural aspects of the Arbitration conducted pursuant to this agreement to arbitrate, including but not limited to, the determination of the issues that are subject to arbitration (i.e., arbitrability), the scope of the

arbitrable issues, the application of this agreement to arbitrate to signatories and non-signatories, shall be decided by the Panel. The Panel shall have the power to award all remedies available under this Agreement and, to the extent not excluded by this Agreement, the applicable law. The Panel shall also have the power to enter such interim orders as it deems necessary, including, without limitation, orders to preserve the subject matter of the Dispute or to preserve or adjust the status of the Parties pending resolution of the Dispute in Arbitration. The Parties agree to accept and honor any interim orders and agree that any such interim orders may be enforced as necessary in any court having relevant jurisdiction. The Panel shall have the power to assess the attorneys’ fees, costs and expenses of the Arbitration (including the arbitrators’ fees and expenses) against one or more of the Parties in whatever manner or allocation it deems appropriate. The Panel shall not decide the Dispute ex aequo et bono or as amiable compositeur or by reliance on any other doctrine or principle that would permit the Panel to avoid the application of this Agreement and/or the governing law. The Panel shall not have the authority to modify or amend any term or provision of this Agreement.

          (d) Parties. This Section 9.15 shall apply to any Dispute between the Parties, and it shall also apply to any (a) Dispute between a Party and any Affiliate of the other Party, (b) Dispute between a Party and any officer, director, employee, representative, agent, successor or assign of the other Party or of an Affiliate of such other Party, (c) Dispute between an Affiliate of one Party and an Affiliate of the other Party, and (d) Dispute between an Affiliate of a Party and an officer, director, employee, representative, agent, successor or assign of the other Party or of an Affiliate of the other Party. With regard to any Dispute, the Affiliates of the Parties and the officers, directors, employees, representatives, agents, successors and assigns of the Parties, and their Affiliates, are intended third party beneficiaries of the agreement to arbitrate set out in this Section 9.15.

          (e) Selection of the Arbitral Panel. The arbitral panel shall be composed of three neutral arbitrators (the “Panel”). The Party requesting arbitration (the “Claimant”) shall appoint one (1) arbitrator at the time it files its request for arbitration with the AAA. The Party named as respondent by the Claimant (“Respondent”) shall appoint one (1) arbitrator within the time specified in the Rules. If a Party fails to appoint an arbitrator, then that arbitrator shall be appointed in accordance with the Rules. The two arbitrators nominated by Claimant and Respondent shall together nominate the third arbitrator, who shall be the Chairman of the Panel, by mutual agreement within fifteen (15) days of the appointment of the second arbitrator. If the party-appointed arbitrators fail to timely appoint a third arbitrator, the AAA shall make the appointment.

          (f) The Award. The award shall be in writing, shall give reasons for the decisions reached by the Tribunal and shall be signed and dated by the arbitrators, and a copy of the award shall be delivered to each of the Parties. The Party against which an award assesses a monetary obligation or enters an injunctive or mandatory order shall pay that obligation or comply with that order on or before the 30th calendar day following the receipt of the award or by such other date as the award may provide. The award shall be final and binding on the parties and may be confirmed in, and judgment upon the award entered by, any court having jurisdiction over the Parties. The Tribunal’s award shall be entitled to all of the protections and benefits of a final judgment as to any Dispute, including compulsory counterclaims, that were or could have

been presented to the Tribunal, and shall be final and binding on the Parties and non-appealable to the maximum extent permitted by law.

          (g) Exclusive Method of Resolving Claims; Assistance of Courts. It is the intent of the Parties that the Arbitration shall be conducted expeditiously, without initial recourse to the courts and without interlocutory appeals of the Panel’s decisions to the courts. However, if a Party refuses to honor its obligations under this agreement to arbitrate, the other Party may obtain appropriate relief staying such litigation and/or compelling arbitration in any court having jurisdiction over the refusing Party; each Party hereby consenting to personal jurisdiction and venue in the federal and State courts in Wilmington, Delaware; in any event, the order compelling arbitration shall require that the arbitration proceedings take place in Wilmington, Delaware and in the manner specified herein. The Parties may apply to any court having relevant jurisdiction for orders requiring witnesses to obey subpoenas issued by the arbitrators. Prior to the appointment of the chairman, a Party may apply to any court having relevant jurisdiction for an order preserving the status quo ante and/or evidence in anticipation of arbitration (for avoidance of doubt, such an application is not intended to constitute waiver of the right to arbitrate Disputes nor does it refer any Dispute to court for decision). Any and all of the Tribunal’s orders and decisions, including, without limitation, interim orders, may be enforced by any court having relevant jurisdiction. Each Party agrees that arbitration pursuant to this Section 9.15 shall be the exclusive method for resolving all Disputes and that it will not commence an action or proceeding, except as provided in this Section 9.15. The Panel’s award may be confirmed in, and judgment upon the award entered by, any federal or State court having jurisdiction over the Parties. Each party hereby consents to personal jurisdiction over itself and its property and venue in the federal and State courts in Wilmington, Delaware.

          (h) Confidentiality. Except to the extent necessary for proceedings relating to enforcement of the arbitration agreement, the award, or other, related rights of the Parties, the fact of the arbitration, the arbitration proceeding itself, all evidence, memorials or other documents exchanged or used in the arbitration and the arbitrators’ award shall be maintained in confidence by the Parties to the fullest extent permitted by applicable law. However, a violation of this covenant shall not affect the enforceability of this agreement to arbitrate or of the arbitrators’ award.

          (i) Severability. The provisions of this agreement to arbitrate are independent of the remaining provisions of the Agreement and the Parties intend that they shall continue in effect even though one or more provisions of the Agreement shall be determined null or void. This agreement to arbitrate shall also survive the termination or expiration of this Agreement.
