The cost of such review and report shall be borne one-half by GSR HOLDINGS and one-half by MLP.

MLP agrees that, unless required by applicable Law, it shall not, and shall not cause or permit any of the Entities to, carry back to any taxable period ending on or prior to the Closing Date any net operating loss or other Tax attribute and further agrees that GSR HOLDINGS has no obligation under this Agreement or otherwise to return or remit any refund or other Tax benefit attributable to a breach by MLP of the foregoing undertaking.

The foregoing costs shall be paid directly by MLP.

(b) If prior to the Closing, GSR HOLDINGS is unable to assign to MIDSTREAM or an Affiliate thereof any capital lease or other agreements due to transfer restrictions set forth therein, then the Parties will enter into commercially reasonable arrangements to grant to GSR HOLDINGS the reasonable equivalent benefits and impose on GSR HOLDINGS the reasonably equivalent obligations in relation to such agreements as if such assignment had been made.

(c) If prior to the Closing, none of the Entities has been assigned the ISDA Agreement dated May 30, 2006 between MEG Inc and Bank of America, N.A. due to transfer restrictions, then the Parties will enter into commercially reasonable arrangements to grant to MLP the reasonable equivalent benefits and impose on MLP the reasonably equivalent obligations in relation to such agreements as if such assignment had been made.

(a) the breach of any of the representations or warranties under Article V;

10.2 Indemnification by GSR HOLDINGS. Effective upon Closing, GSR HOLDINGS shall defend, indemnify and hold harmless MLP and its Affiliates, and all of its and their directors, officers, employees, partners, members, contractors, agents, and representatives (collectively, the “MLP Indemnitees”) from and against any and all Losses asserted against, resulting from, imposed upon or incurred by any of the MLP Indemnitees as a result of or arising out of:

(c) the breach of any of the representations or warranties under Sections 4.1 and 4.2 or the covenants or agreements of GSR HOLDINGS or MIDSTREAM contained in this Agreement; and

(d) any Reserved Liabilities.

10.3 Survival and Certain Limitations.

(a) Subject to this Section 10.3, all representations, warranties, covenants and indemnities made by the Parties in this Agreement or pursuant hereto shall survive the Closing as hereinafter provided, and shall not be merged into any instruments or agreements delivered at Closing.

(b) With respect to the obligations of GSR HOLDINGS under Section 10.2(a), none of the MLP Indemnitees shall be entitled to assert any right to indemnification after one (1) year from the Closing.

(c) With respect to the obligations of GSR HOLDINGS under Section 10.2(b), GSR HOLDINGS shall, at the direction and sole cost, expense and liability of MLP, take reasonable enforcement action against such Sellers under the Stock Purchase Agreement and pay to MLP any proceeds actually received by GSR HOLDINGS from the Sellers on account of such enforcement action. MLP shall be entitled to select any counsel required for such enforcement (unless GSR HOLDINGS has independent claims against the Sellers that are being advanced contemporaneously, in which case GSR HOLDINGS shall be entitled to select counsel for all such claims, with (i) the costs of such counsel to be shared between MLP and GSR HOLDINGS in proportion to the amounts claimed by the Parties and (ii) any settlement thereof requiring the consent of both Parties).

(d) Any claim for indemnity under this Agreement made by a Party Indemnitee shall be in writing, be delivered in good faith prior to the respective survival period under Section 10.3(b) (to the extent applicable), and specify in reasonable detail the specific nature of the claim for indemnification hereunder (“Claim Notice”). Any such claim that is described in a timely (if applicable) delivered Claim Notice shall survive with respect to the specific matter described therein.

(e) Notwithstanding anything contained herein to the contrary, in no event shall GSR HOLDINGS be obligated under this Agreement to indemnify (or be otherwise liable hereunder in any way whatsoever to) any of the MLP Indemnitees with respect to a breach of any representation or warranty (other than under Section 10.2(b) in respect of breaches of representations or warranties of the Sellers under the Stock Purchase Agreement), if MLP had Knowledge thereof at Closing and failed to notify GSR HOLDINGS of such breach prior to Closing. Unless GSR HOLDINGS or a Third Person shall have made a claim or demand or it appears reasonably likely that such a claim or demand appears reasonably likely, MLP shall not take any voluntary action that is intended by MLP to cause a Claim to be initiated that would be subject to indemnification by GSR HOLDINGS (other than under Section 10.2(b)).

(f) All Losses indemnified hereunder shall be determined net of any (i) Third Person Awards, (ii) Tax Benefits; and (iii) amount which specifically pertains to such Loss and is reflected in the calculations of the amounts set forth on the Final Settlement Statement.

10.4 Notice of Asserted Liability; Opportunity to Defend.

(a) All claims for indemnification hereunder (other than under Section 10.2(b)) shall be subject to the provisions of this Section 10.4. Any person claiming indemnification hereunder is referred to herein as the “Indemnified Party” or “Indemnitee” and any person against whom such claims are asserted hereunder is referred to herein as the “Indemnifying Party” or “Indemnitor.”

(b) If any Claim is asserted against or any Loss is sought to be collected from an Indemnified Party, the Indemnified Party shall with reasonable promptness provide to the Indemnifying Party a Claim Notice. The failure to give any such Claim Notice shall not otherwise affect the rights of the Indemnified Party to indemnification hereunder unless the Indemnified Party has proceeded to contest, defend or settle such Claim or remedy such a Loss with respect to which it has failed to give a Claim Notice to the Indemnifying Party, but only to the extent the Indemnifying Party is prejudiced thereby. Additionally, to the extent the Indemnifying Party is prejudiced thereby, the failure to provide a Claim Notice to the Indemnifying Party shall relieve the Indemnifying Party from liability for such Claims and Losses that it may have to the Indemnified Party, but only to the extent the liability for such Claims or Losses is directly attributable to such failure to provide the Claim Notice.

(c) The Indemnifying Party shall have thirty (30) days from the personal delivery or receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not it disputes the liability to the Indemnified Party hereunder with respect to the Claim or Loss, and in the event of a dispute, such dispute shall be resolved in the manner set forth in Section 11.8 hereof, (ii) in the case where Losses are asserted against or sought to be collected from an Indemnifying Party by the Indemnified Party, whether or not the Indemnifying Party shall at its own sole cost and expense remedy such Losses or (iii) in the case where Claims are asserted against or sought to be collected from an Indemnified Party, whether or not the Indemnifying Party shall at its own sole cost and expense defend the Indemnified Party against such Claim; provided however, that any Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party (and of which it shall have given notice and opportunity to comment to the Indemnifying Party) and not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party does not give notice to the Indemnified Party of its election to contest and defend any such Claim described in Section 10.4(c)(iii) within the Notice Period, then the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party and shall be responsible for all costs incurred in connection therewith.

(e) If the Indemnifying Party is obligated to defend and indemnify the Indemnified Party, and the Parties have a conflict of interest with respect to any such Claim, then the Indemnified Party may, in its sole discretion, separately and independently contest and defend such Claim, and the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party and shall be responsible for all costs incurred in connection therewith.

(f) If the Indemnifying Party notifies the Indemnified Party within the Notice Period that it shall defend the Indemnified Party against a Claim, the Indemnifying Party shall have the right to defend all appropriate Proceedings, and with counsel of its own choosing (but reasonably satisfactory to the Indemnified Party) and such Proceedings shall be promptly settled (subject to obtaining a full and complete release of all Indemnified Parties) or prosecuted by it to a final conclusion. If the Indemnified Party desires to participate in, but not control, any such defense or settlement it may do so at its sole cost and expense. If the Indemnified Party joins in any such Claim, the Indemnifying Party shall have full authority to determine all action to be taken with respect thereto, as long as such action could not create a liability to any of the Indemnified Parties, in which case, such action would require the prior written consent of any Indemnified Party so affected.

(g) If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Claim and in making any counterclaim against the Third Person asserting the Claim, or any cross-complaint against any person as long as such cooperation, counterclaim or cross-complaint could not create a liability to any of the Indemnified Parties.

(h) At any time after the commencement of defense by Indemnifying Party under Section 10.4(f) above of any Claim, the Indemnifying Party may request the Indemnified Party to agree in writing to the abandonment of such contest or to the payment or compromise by the Indemnifying Party of the asserted Claim, but only if the Indemnifying Party agrees in writing to be solely liable for such Claim; whereupon such action shall be taken unless the Indemnified Party determines that the contest should be continued and notifies the Indemnifying Party in writing within fifteen (15) days of such request from the Indemnifying Party. If the Indemnified Party determines that the contest should be continued, the amount for which the Indemnifying Party would otherwise be liable hereunder shall not exceed the amount which the Indemnifying Party had agreed to pay to compromise such Claim; provided that, the other Person to the contested Claim had agreed in writing to accept such amount in payment or compromise of the Claim as of the time the Indemnifying Party made its request therefor to the Indemnified Party, and further provided that, under such proposed compromise, the Indemnified Party would be fully and completely released from any further liability or obligation with respect to the matters which are the subject of such contested Claim.

10.5 Materiality Conditions. For purposes of determining whether an event described in this Article X has occurred for which indemnification under this Article X can be sought (other than under Section 10.2(b)), any requirement in any representation, warranty, covenant or agreement by GSR HOLDINGS or MLP, as applicable, contained in this Agreement that an event or fact be “material,” “Material,” meet a certain minimum dollar threshold or have a “Material Adverse Effect” or a material adverse effect (each a “Materiality Condition”) in order for such event or fact to constitute a misrepresentation or breach of such representation, warranty, covenant or agreement under this Agreement, such Materiality Condition shall be disregarded and such representations, warranties, covenants or agreements shall be construed solely for purposes of this Article X as if they did not contain such Materiality Conditions. Notwithstanding anything in this Section 10.5, any claim for indemnification under this Article X will be subject to Section 10.3.

10.6 Exclusive Remedy. AS BETWEEN THE MLP INDEMNITEES AND THE GSR HOLDINGS INDEMNITEES, AFTER CLOSING (A) THE EXPRESS INDEMNIFICATION PROVISIONS SET FORTH IN THIS AGREEMENT, WILL BE THE SOLE AND EXCLUSIVE RIGHTS, OBLIGATIONS AND REMEDIES OF THE PARTIES WITH RESPECT TO SAID AGREEMENT AND THE EVENTS GIVING RISE THERETO, AND THE TRANSACTIONS PROVIDED FOR THEREIN OR CONTEMPLATED THEREBY (OTHER THAN THE OTHER TRANSACTION DOCUMENTS) AND (B) NEITHER PARTY NOR ANY OF ITS RESPECTIVE SUCCESSORS OR ASSIGNS SHALL HAVE ANY RIGHTS AGAINST THE OTHER PARTY OR ITS AFFILIATES WITH RESPECT TO THE TRANSACTIONS PROVIDED FOR HEREIN OTHER THAN AS IS EXPRESSLY PROVIDED IN THIS AGREEMENT AND THE OTHER TRANSACTION DOCUMENTS.

10.7 Negligence and Strict Liability Waiver. WITHOUT LIMITING OR ENLARGING THE SCOPE OF THE INDEMNIFICATION OBLIGATIONS SET FORTH IN THIS AGREEMENT, AN INDEMNIFIED PARTY SHALL BE ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF WHETHER THE LOSS OR CLAIM GIVING RISE TO SUCH INDEMNIFICATION OBLIGATION IS THE RESULT OF THE SOLE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY, OR VIOLATION OF ANY LAW OF OR BY SUCH INDEMNIFIED PARTY.

10.8 Limitation on Damages. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL ANY OF GSR HOLDINGS OR MLP BE LIABLE TO THE OTHER, OR TO THE OTHERS’ INDEMNITEES, UNDER THIS AGREEMENT FOR ANY EXEMPLARY, PUNITIVE, REMOTE, SPECULATIVE, CONSEQUENTIAL, SPECIAL OR INCIDENTAL DAMAGES OR LOSS OF PROFITS; PROVIDED THAT, IF ANY OF THE GSR HOLDINGS INDEMNITEES OR MLP INDEMNITEES IS HELD LIABLE TO A THIRD PERSON FOR ANY SUCH DAMAGES AND THE INDEMNITOR IS OBLIGATED TO INDEMNIFY SUCH GSR HOLDINGS INDEMNITEES OR MLP INDEMNITEES FOR THE MATTER THAT GAVE RISE TO SUCH DAMAGES, THE INDEMNITOR SHALL BE LIABLE FOR, AND OBLIGATED TO REIMBURSE SUCH INDEMNITEES FOR SUCH DAMAGES.

10.9 Bold and/or Capitalized Letters. THE PARTIES AGREE THAT THE BOLD AND/OR CAPITALIZED LETTERS IN THIS AGREEMENT CONSTITUTE CONSPICUOUS LEGENDS.

ARTICLE XI

MISCELLANEOUS PROVISIONS

11.1 Expenses. Unless otherwise specifically provided for herein, each Party will bear its own costs and expenses (including legal fees and expenses) incurred in connection with the negotiation of this Agreement and the transactions contemplated hereby; provided that GSR HOLDINGS will bear the cost of all Post-Closing Consents which must be obtained from any railroad.

11.2 Further Assurances. From time to time, and without further consideration, each Party will execute and deliver to the other Party such documents and take such actions as the other Party may reasonably request in order to more effectively implement and carry into effect the transactions contemplated by this Agreement.

11.3 Transfer Taxes. The Parties believe that the contribution of the Subject Interests as provided for herein is exempt from or is otherwise not subject to any and all sales, use, transfer, or similar Taxes. If any such sales, transfer, use or similar Taxes are due or should hereafter become due (including penalty and interest thereon) by reason of this transaction, MLP shall timely pay and solely bear all such type of Taxes.

11.4 Assignment. Neither Party may assign this Agreement or any of its rights or obligations arising hereunder without the prior written consent of the other Party; provided, however, MLP shall be permitted to assign this Agreement to an Affiliate prior to Closing, provided, that, notwithstanding such assignment, MLP shall continue to remain responsible for all obligations of MLP hereunder following such assignment.

11.5 Entire Agreement, Amendments and Waiver. This Agreement, together with the Transaction Documents and all certificates, documents, instruments and writings that are delivered pursuant hereto and thereto contain the entire understanding of the Parties with respect to the transactions contemplated hereby and supersede all prior agreements, arrangements and understandings relating to the subject matter hereof. This Agreement may be amended, superseded or canceled only by a written instrument duly executed by the Parties specifically stating that it amends, supersedes or cancels this Agreement. Any of the terms of this Agreement and any condition to a Party’s obligations hereunder may be waived only in writing by that Party specifically stating that it waives a term or condition hereof. No waiver by either Party of any one or more conditions or defaults by the other in performance of any of the provisions of this Agreement shall operate or be construed as a waiver of any future conditions or defaults, whether of a like or different character, nor shall the waiver constitute a continuing waiver unless otherwise expressly provided.

11.6 Severability. Each portion of this Agreement is intended to be severable. If any term or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity of the remainder of this Agreement.

11.7 Counterparts. This Agreement may be executed simultaneously in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

11.8 Governing Law, Dispute Resolution and Arbitration.

(a) Governing Law. This Agreement shall be governed by, enforced in accordance with, and interpreted under, the Laws of the State of Colorado, without reference to conflicts of Laws principles.

(b) Negotiation. In the event of any Arbitral Dispute, the Parties shall promptly seek to resolve any such Arbitral Dispute by negotiations between senior executives of the Parties who have authority to settle the Arbitral Dispute. When a Party believes there is an Arbitral Dispute under this Agreement that Party will give the other Party written notice of the Arbitral Dispute. Within thirty (30) days after receipt of such notice, the receiving Party shall submit to the other a written response. Both the notice and response shall include (i) a statement of each Party’s position and a summary of the evidence and arguments supporting such position, and (ii) the name, title, fax number, and telephone number of the executive or executives who will represent that Party. If the Arbitral Dispute involves a claim arising out of the actions of any Person not a signatory to this Agreement, the receiving Party shall have such additional time as necessary, not to exceed an additional thirty (30) days, to investigate the Arbitral Dispute before submitting a written response. The executives shall meet at a mutually acceptable time and place within fifteen (15) days after the date of the response and thereafter as often as they reasonably deem necessary to exchange relevant information and to attempt to resolve the Arbitral Dispute. If one of the executives intends to be accompanied at a meeting by an attorney, the other executive shall be given at least five (5) Business Days’ notice of such intention and may also be accompanied by an attorney.

(c) Failure to Resolve. If the Arbitral Dispute has not been resolved within sixty (60) days after the date of the response given pursuant to Section 11.8(b) above, or such additional time, if any, that the Parties mutually agree to in writing, or if the Party receiving such notice denies the applicability of the provisions of Section 11.8(b) or otherwise refuses to participate under the provisions of Section 11.8(b), either Party may initiate binding arbitration pursuant to the provisions of Section 11.8(d) below.

(d) Arbitration. Any Arbitral Disputes not settled pursuant to the foregoing provisions shall be resolved through the use of binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“Arbitration Rules”), as supplemented to the extent necessary to determine any procedural appeal questions by the Federal Arbitration Act (Title 9 of the United States Code) and in accordance with the following provisions:

(i) If there is any inconsistency between this Section 11.8(d) and the Arbitration Rules or the Federal Arbitration Act, the terms of this Section 11.8(d) will control the rights and obligations of the Parties.

(ii) Arbitration shall be initiated by a Party serving written notice, via certified mail, on the other Party that the first Party elects to refer the Arbitral Dispute to binding arbitration, along with the name of the arbitrator appointed by the Party demanding arbitration and a statement of the matter in controversy. Within thirty (30) days after receipt of such demand for arbitration, the receiving Party shall name its arbitrator. If the receiving Party fails or refuses to name its arbitrator within such thirty (30) day period, the second arbitrator shall be appointed, upon request of the Party demanding arbitration, by the Chief U.S. District Court Judge for the District of Colorado, or such other person designated by such judge. The two arbitrators so selected shall within thirty (30) days after their designation select a third arbitrator; provided, however, that if the two arbitrators are not able to agree on a third arbitrator within such thirty (30) day period, either Party may request the Chief U.S. District Court Judge for the District of Colorado, or such other person designated by such judge to select the third arbitrator as soon as possible. If the Judge declines to appoint an arbitrator, appointment shall be made, upon application of either Party, pursuant to the Commercial Arbitration Rules of the American Arbitration Association. If any arbitrator refuses or fails to fulfill his or her duties hereunder, such arbitrator shall be replaced by the Party which selected such arbitrator (or if such arbitrator was selected by another Person, through the procedure which such arbitrator was selected) pursuant to the foregoing provisions.

(iii) The hearing will be conducted in Denver, Colorado, no later than sixty (60) days following the selection of the arbitrators or thirty (30) days after all prehearing discovery has been completed, whichever is later, at which the Parties shall present such evidence and witnesses as they may choose, with or without counsel. The Parties and the arbitrators should proceed diligently and in good faith in order that the award may be made as promptly as possible.

(iv) Except as provided in the Federal Arbitration Act, the decision of the arbitrators will be binding on and non-appealable by the Parties. Any such decision may be filed in any court of competent jurisdiction and may be enforced by any Party as a final judgment in such court.

(v) The arbitrators shall have no right or authority to grant or award exemplary, punitive, remote, speculative, consequential, special or incidental damages.

(vi) The Federal Rules of Civil Procedure, as modified or supplemented by the local rules of civil procedure for the U.S. District Court of Colorado, shall apply in the arbitration. The Parties shall make their witnesses available in a timely manner for discovery pursuant to such rules. If a Party fails to comply with this discovery agreement within the time established by the arbitrators, after resolving any discovery disputes, the arbitrators may take such failure to comply into consideration in reaching their decision. All discovery disputes shall be resolved by the arbitrators pursuant to the procedures set forth in the Federal Rules of Civil Procedure.

(vii) Adherence to formal rules of evidence shall not be required. The arbitrators shall consider any evidence and testimony that they determine to be relevant.

(viii) The Parties hereby request that the arbitrators render their decision within thirty (30) days following conclusion of the hearing.

(ix) The defenses of statute of limitations and laches shall be tolled from and after the date a Party gives the other Party written notice of an Arbitral Dispute as provided in Section 11.8(b) above until such time as the Arbitral Dispute has been resolved pursuant to Section 11.8(b), or an arbitration award has been entered pursuant to this Section 11.8(d).

(e) Recovery of Costs and Attorneys’ Fees. If arbitration arising out of this Agreement is initiated by either Party, the decision of the arbitrators may include the award of court costs, fees and expenses of such arbitration (including reasonable attorneys’ fees).

(f) Choice of Forum. If, despite the Parties’ agreement to submit any Arbitral Disputes to binding arbitration, there are any court proceedings arising out of or relating to this Agreement or the transactions contemplated hereby, such proceedings shall be brought and tried in, and the Parties hereby consent to the jurisdiction of, the federal or state courts situated in the City and County of Denver, State of Colorado.

(g) Jury Waivers. THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY.

(h) Settlement Proceedings. All aspects of any settlement proceedings, including discovery, testimony and other evidence, negotiations and communications pursuant to this Section 11.8, briefs and the award shall be held confidential by each Party and the arbitrators, and shall be treated as compromise and settlement negotiations for the purposes of the Federal and State Rules of Evidence.

11.9 Notices and Addresses. Any notice, request, instruction, waiver or other communication to be given hereunder by either Party shall be in writing and shall be considered duly delivered if personally delivered, mailed by certified mail with the postage prepaid (return receipt requested), sent by messenger or overnight delivery service, or sent by facsimile to the addresses of the Parties as follows:
