(a) Notwithstanding any other provision herein to the contrary, the General Partner shall be obligated to cause a Partnership Group Member to elect, not later than two years after receipt by the General Partner of the Commencement Notice (as defined below) with respect to a particular Retained Asset, to purchase such Retained Asset for a purchase price equal to the fair market value thereof, such purchase to be effected in accordance with the procedures set forth below in this Section 2.3(a) (or if such an election is not made by the second anniversary of the receipt of the Commencement Notice, it will be deemed made in accordance with Section 2.3(a)(ii) below). Following the commencement of commercial service with respect to any Retained Asset but prior to the purchase of such Retained Asset by a Partnership Group Member pursuant to this Section 2.3(a), the applicable Quicksilver Entity will pay to the applicable Partnership Group Member a fee for operating such Retained Asset.

(i) Not later than 60 days after a Quicksilver Entity completes construction of a Retained Asset and such Retained Asset commences commercial service, such Quicksilver Entity shall notify the General Partner in writing of such commencement (the

“Commencement Notice”). The Commencement Notice shall (w) set forth the Quicksilver Entity’s good faith estimate of the actual Construction Costs for such Retained Asset, (x) include an offer to sell such Retained Asset to a Partnership Group Member to be designated by the General Partner at the fair market value thereof determined as provided in Section 2.3(a)(iii) or Section 2.3(a)(iv), (y) include any other proposed terms relating to the purchase of such Retained Asset, and, (z) if the Quicksilver Entity desires to utilize such Retained Asset after the purchase of such Retained Asset by a Partnership Group Member in accordance with this Section 2.3(a), include commercially reasonable terms on which the Partnership Group will provide services to such Quicksilver Entity to enable it to so utilize such Retained Asset (clauses (y) and (z) herein are collectively referred to as the “Other Notice Terms”).

(ii) The General Partner shall notify the applicable Quicksilver Entity, which notice shall be in writing, of the exercise by the General Partner of its election to purchase such Retained Asset (such notice, the “Retained Asset Election Notice”), and if the General Partner fails to furnish such a Retained Asset Election Notice to the applicable Quicksilver Entity on or before the second anniversary of the General Partner’s receipt of a Commencement Notice, the General Partner shall be deemed to have delivered, and the applicable Quicksilver Entity to have received, a Retained Asset Election Notice on such second anniversary.

(iii) In the event that the applicable Quicksilver Entity and the General Partner (with the concurrence of the Conflicts Committee) within 60 days after the receipt or deemed receipt by the applicable Quicksilver Entity of the Retained Asset Election Notice are able to agree on the fair market value of the Retained Asset that is subject to the Commencement Notice and the Other Notice Terms, a Partnership Group Member shall purchase the Retained Asset for the agreed upon fair market value as soon as commercially practicable after such agreement has been reached and, if applicable, enter into an agreement with the applicable Quicksilver Entity to provide services in a manner consistent with the Commencement Notice.

(iv) In the event that the applicable Quicksilver Entity and the General Partner (with the concurrence of the Conflicts Committee) are unable to agree within 60 days after the receipt by the applicable Quicksilver Entity of the Retained Asset Election Notice on the fair market value of the Retained Asset that is subject to the Commencement Notice, the applicable Quicksilver Entity and the General Partner will engage a mutually agreed upon independent investment banking firm or other independent Person that is an expert in valuing midstream energy assets such as the Retained Asset that is subject to the Commencement Notice (“Retained Asset Valuation Expert”) to determine the fair market value of such Retained Asset. Such Retained Asset Valuation Expert will determine the fair market value of such Retained Asset within 30 days of its engagement and furnish the applicable Quicksilver Entity and the General Partner its determination, which determination shall be a final and binding determination of the fair market value to be paid by the Partnership Group Member for the Retained Asset. The fees of the Retained Asset Valuation Expert will be split equally between Quicksilver and the MLP.

(v) If the applicable Quicksilver Entity and the General Partner are unable to agree within 60 days after the receipt by the applicable Quicksilver Entity of the Retained Asset Election Notice on all of the Other Notice Terms, the applicable Quicksilver Entity and the General Partner will obtain a good faith proposal from a mutually agreed upon third party engaged in the business to which such Other Notice Terms relate in order to determine the Other Notice Terms on which the General Partner and the applicable Quicksilver Entity are unable to agree. Such third party will submit a good faith proposal regarding the Other Notice Terms on which the General Partner and the applicable Quicksilver Entity are unable to agree within 30 days of its engagement and furnish the applicable Quicksilver Entity and the General Partner its proposal, which determination shall be a final and binding determination of the Other Notice Terms. The fees of the third party will be split equally between the applicable Quicksilver Entity and the Partnership Group.

(vi) Once the fair market value and the Other Notice Terms have been finally determined pursuant to sub-clauses (iii), (iv) or (v) above, the General Partner will have the obligation to cause a Partnership Group Member to purchase the Retained Assets that are the subject of the Retained Asset Election Notice as modified by the determination of the Retained Asset Valuation Expert and/or the third party submitting a proposal as soon as commercially practicable after such determination and, if applicable, enter into an agreement with the applicable Quicksilver Entity to provide services in a manner consistent with the Commencement Notice, as modified by the determination of the third party submitting a proposal, if applicable.

(b) In the event that a Quicksilver Entity becomes aware of an opportunity to make an acquisition that includes Subject Assets, then the applicable Quicksilver Entity may make such acquisition without first offering the opportunity to the MLP as long as it complies with the following procedures:

(i) Within 120 days after the consummation of such an acquisition, the applicable Quicksilver Entity shall notify the General Partner in writing of such acquisition. Such notice shall include an offer (the “Offer”) by the applicable Quicksilver Entity to sell the Subject Assets to the MLP, accompanied by a proposed definitive agreement to effectuate the purchase and sale of the Subject Assets (the “Purchase Agreement”). The Purchase Agreement shall set forth the material terms of the Offer, including the proposed purchase price, any liabilities to be assumed by the Partnership Group and the other material terms of the Offer; provided, that the representations and warranties regarding the Subject Assets shall be substantially consistent with the terms contained in the definitive purchase agreement pursuant to which the applicable Quicksilver Entity acquired the Subject Assets, subject to such adjustments as the applicable Quicksilver Entity reasonably determines are necessary to reflect the differences in the transaction. In addition, if any Quicksilver Entity desires to utilize the Subject Assets, the Offer may include commercially reasonable terms on which the Partnership Group will provide services to such Quicksilver Entity to enable it to utilize the Subject Assets.

(ii) As soon as practicable after the Offer is made, the applicable Quicksilver Entity will deliver to the MLP all information prepared by or on behalf of or in the possession of any Quicksilver Entity related to the Subject Assets and reasonably requested by the MLP. As soon as practicable, but in any event within 60 days after receipt of the Offer accompanied by the form of Purchase Agreement, the General Partner shall notify the Quicksilver Entity in writing that either: (x) the General Partner, on behalf of the Partnership Group, has elected (with the concurrence of the Conflicts Committee) not to cause a Partnership Group Member to purchase the Subject Assets, in which event the Quicksilver Entities shall be forever free to continue to own or operate such Subject Assets, or (y) the General Partner, on behalf of the Partnership Group, has elected (with the concurrence of the Conflicts Committee) to cause a Partnership Group Member to purchase the Subject Assets, in which event sub-clauses (iii) and (iv) shall apply.

(iii) In the event that the applicable Quicksilver Entity and the General Partner (with the concurrence of the Conflicts Committee) within 60 days after receipt by the General Partner of the Offer are able to agree on the fair market value of the Subject Assets that are subject to the Offer accompanied by the form of Purchase Agreement and the other terms of the Offer including, without limitation, the terms, if any, on which the Partnership Group will provide services to any Quicksilver Entity to enable it to utilize the Subject Assets, a Partnership Group Member shall purchase the Subject Assets for the agreed upon fair market value as soon as commercially practicable after such agreement has been reached and, if applicable, enter into an agreement with any Quicksilver Entity to provide services in a manner consistent with the Offer.

(iv) In the event that the applicable Quicksilver Entity and the General Partner (with the concurrence of the Conflicts Committee) are unable to agree within 60 days after receipt by the General Partner of the Offer on the fair market value of the Subject Assets that are subject to the Offer or the other terms of the Offer including, if applicable, the terms on which the Partnership Group will provide services to any Quicksilver Entity to enable it to utilize the Subject Assets, the applicable Quicksilver Entity and the General Partner will engage a mutually agreed upon independent investment banking firm or other independent Person that is an expert in valuing midstream assets like the Subject Assets (such firm or Person, the “Subject Assets Valuation Expert”) to determine the fair market value of the Subject Assets and/or the other terms on which the General Partner and the Quicksilver Entity are unable to agree. Such Subject Assets Valuation Expert will determine the fair market value of the Subject Assets and/or the other terms on which the General Partner and the applicable Quicksilver Entity are unable to agree within 30 days of its engagement and furnish the applicable Quicksilver Entity and the General Partner its determination. The fees of the Subject Assets Valuation Expert will be split equally between Quicksilver and the MLP. Once the Subject Assets Valuation Expert has submitted its determination of the fair market value of the Subject Assets and/or the other terms on which the Partnership Group and the applicable Quicksilver Entity are unable to agree, the General Partner will have the right, but not the obligation, subject to the concurrence of the Conflicts Committee, to cause a Partnership Group Member to purchase the Subject Assets pursuant to the Offer as modified by the determination of the Subject Assets Valuation Expert. The Partnership Group Member

will provide written notice of its decision to the Quicksilver Entity within 30 days after the Subject Assets Valuation Expert has submitted its determination. Failure to provide such notice within such 30-day period shall be deemed to constitute a decision not to purchase the Subject Assets. If the General Partner elects to cause a Partnership Group Member to purchase the Subject Assets, then the Partnership Group Member shall purchase the Subject Assets pursuant to the Offer as modified by the determination of the Valuation Expert as soon as commercially practicable after such determination and, if applicable, enter into an agreement with the applicable Quicksilver Entity to provide services in a manner consistent with the Offer, as modified by the determination of the Subject Assets Valuation Expert, if applicable.

(c) In the event that a Quicksilver Entity determines to construct Subject Assets (other than a Gathering System Expansion, which shall be subject to the rights of the Partnership Group pursuant to Section 4.4 of the Gathering and Processing Agreement), then the applicable Quicksilver Entity may construct or cause to be constructed such Subject Assets without first offering the opportunity to construct and own same to the MLP if such Quicksilver Entity complies with the following procedures:

	(i)		Within 120 days after the completion of construction and the commencement of commercial service of such Subject Assets by a Quicksilver Entity, the applicable Quicksilver Entity shall notify the General Partner in writing of such construction and offer the Partnership Group the opportunity to purchase such Subject Assets in accordance with this Section 2.3(c) (the “Construction Offer”). The Construction Offer shall set forth the Quicksilver Entity’s good faith estimate of (A) the actual Construction Costs for the Subject Assets incurred by the applicable Quicksilver Entity, and (B) the fair market value of such Subject Assets, which fair market value shall constitute the proposed purchase price for the Subject Assets, together with the other proposed terms relating to the purchase of the Subject Assets, and, if any Quicksilver Entity desires to utilize the Subject Assets, the Construction Offer may also include commercially reasonable terms on which the Partnership Group will provide services to such Quicksilver Entity to enable it to utilize the Subject Assets (collectively, the “Other Construction Terms”).

	(ii)		As soon as practicable, but in any event within 60 days after receipt of such written notification, the General Partner shall notify the applicable Quicksilver Entity in writing that either (x) the General Partner, on behalf of the Partnership Group, has elected (with the concurrence of the Conflicts Committee) not to cause a Partnership Group Member to purchase the Subject Assets, in which event the Quicksilver Entities shall be forever free to continue to own or operate such Subject Assets, or (y) the General Partner, on behalf of the Partnership Group, has elected (with the concurrence of the Conflicts Committee) to cause a Partnership Group Member to purchase the Subject Assets, in which event the following procedures shall apply:

	(iii)		In the event that the applicable Quicksilver Entity and the General Partner (with the concurrence of the Conflicts Committee) within 60 days after receipt by the

			General Partner of the Construction Offer are able to agree on the fair market value of the Subject Assets that are subject to the Construction Offer and the Other Construction Terms of the Construction Offer, a Partnership Group Member shall purchase the Subject Assets for the agreed upon fair market value as soon as commercially practicable after such agreement has been reached and, if applicable, enter into an agreement with the Quicksilver Entity to provide services in a manner consistent with the Construction Offer.

	(iv)		In the event that the applicable Quicksilver Entity and the General Partner (with the concurrence of the Conflicts Committee) are unable to agree within 60 days after receipt by the General Partner of the Construction Offer on the fair market value of the Subject Assets that are subject to the Construction Offer, the applicable Quicksilver Entity and the General Partner will engage a mutually agreed upon independent investment banking firm or other independent Person that is an expert in valuing midstream assets such as the Subject Assets that are the subject of the Construction Offer (the “Independent Expert”), to determine the fair market value of the Subject Assets. Such Independent Expert will determine the fair market value of the Subject Assets within 30 days of its engagement and furnish the applicable Quicksilver Entity and the General Partner its determination, which determination shall be a final and binding determination of the fair market value. The fees of the Independent Expert will be split equally between Quicksilver and the MLP.

	(v)		If the applicable Quicksilver Entity and the General Partner are unable to agree within 60 days after receipt by the General Partner of the Construction Offer on all of the Other Construction Terms, the applicable Quicksilver Entity and the General Partner will obtain a good faith proposal from a mutually agreed upon third party engaged in the business to which such Other Construction Terms relate in order to determine the Other Construction Terms on which the General Partner and the applicable Quicksilver Entity are unable to agree. Such third party will submit a good faith proposal regarding the Other Construction Terms on which the General Partner and the applicable Quicksilver Entity are unable to agree within 30 days of its engagement and furnish the applicable Quicksilver Entity and the General Partner its proposal, which determination shall be a final and binding determination of the Other Construction Terms. The fees of the third party will be split equally between the applicable Quicksilver Entity and the Partnership Group.

	(vi)		Once the fair market value and the Other Construction Terms have been finally determined pursuant to sub-clauses (iii), (iv) or (v) above, the General Partner will have the right, but not the obligation, subject to the concurrence of the Conflicts Committee, to cause a Partnership Group Member to purchase the Subject Assets pursuant to the Construction Offer as modified by the determination of the Independent Expert and/or the third party submitting a proposal, as applicable. The Partnership Group Member will provide written notice of its decision to the applicable Quicksilver Entity within 30 days after the later of the date on which the Independent Expert and/or the third party submitting a proposal, as applicable,

has submitted its determination. Failure to provide such notice within such 30-day period shall be deemed to constitute a decision not to purchase the Subject Assets. If the General Partner elects to cause a Partnership Group Member to purchase the Subject Assets, then the Partnership Group Member shall purchase the Subject Assets pursuant to the Construction Offer as modified by the determination of the Independent Expert and/or the third party submitting a proposal as soon as commercially practicable after such determination and, if applicable, enter into an agreement with the applicable Quicksilver Entity to provide services in a manner consistent with the Construction Offer, as modified by the determination of the third party submitting a proposal, if applicable.

(d) The procedures set forth in Section 2.3(c) shall not apply to any Gathering System Expansion, which shall be subject to the rights and obligations set forth in Section 4.4 of the Gathering and Processing Agreement; provided, however, that any determination by any Partnership Group Member not to exercise its right to acquire a Gathering System Expansion or to permit such right to expire unexercised shall be subject to the concurrence of the Conflicts Committee.

(b) the failure of the Partnership Group to have on the Closing Date any consent or governmental permit necessary to allow (i) the transfer of any of the MLP Assets to the Partnership Group on the Closing Date or (ii) the Partnership Group to use or operate the MLP Assets in substantially the same manner that the MLP Assets were owned and operated by the Quicksilver Entities immediately prior to the Closing Date;

(c) all federal, state and local income tax liabilities attributable to the ownership or operation of the MLP Assets prior to the Closing Date, including (i) any such income tax liabilities of the Quicksilver Entities that may result from the consummation of the formation transactions for the Partnership Entities and (ii) any income tax liabilities arising under Treasury Regulation Section 1.1502-6 and any similar provision from state, local or foreign applicable law, by contract, as successor, transferred or otherwise and which income tax is attributable to having been a member of any consolidated, combined or unitary group prior to the Closing Date;

(d) the fire, personal injury and related personal and property damage arising from the accident at the Cowtown Gas Processing Facility that occurred on May 25, 2007;

provided, however, that, (i) in the case of clauses (a) and (b) above, such indemnification obligations shall survive for two (2) years from the Closing Date; (ii) in the case of clause (c) above, such indemnification obligation shall survive until 12:01 a.m. of the first day after the expiration of any applicable statute of limitations; and (iii) in the case of clause (d) above, such indemnification obligation shall survive indefinitely.

3.3 Limitations Regarding Indemnification.

(a) Notwithstanding anything herein to the contrary, in no event shall the Indemnifying Party have any indemnification obligations under this Agreement for claims made as a result of additions to or modifications of Environmental Laws promulgated after the Closing Date.

(b) Notwithstanding anything herein to the contrary, the liability of the Indemnifying Party for any indemnification obligations under this Agreement will be subject to reduction for (i) any insurance proceeds realized by the Indemnified Party with respect to the indemnified matter, net of any premium that becomes due and payable as a result of such claim and (ii) any amounts recovered by the Indemnified Party under contractual indemnities from third parties. The MLP hereby agrees to use commercially reasonable efforts to realize any applicable insurance proceeds and amounts recoverable under such contractual indemnities.

(c) The liability of the Indemnifying Party for any indemnification obligations under this Agreement will be reduced by any amounts reserved or accrued for such Losses on the consolidated balance sheet of the Partnership Group as of December 31, 2006.

3.4 Indemnification by the Partnership Group. In addition to and not in limitation of the indemnification provided under the MLP Agreement, the Partnership Group shall indemnify, defend and hold harmless the Quicksilver Entities from and against any Losses (excluding Environmental Losses) suffered or incurred by the Quicksilver Entities by reason of or arising out of events and conditions associated with the operation of the MLP Assets and occurring on or after the Closing Date, unless in any such case indemnification would not be permitted under the MLP Agreement by reason of one of the provisos contained in Section 7.7 of the MLP Agreement.

3.5 Indemnification Procedures.

(a) The Indemnified Party agrees that within thirty (30) days after it becomes aware of facts giving rise to a claim for indemnification pursuant to this Article III, it will provide notice thereof in writing to the Indemnifying Party specifying the nature of and specific basis for such claim; provided, however, that the Indemnified Party shall not submit claims more frequently than once a calendar quarter (or twice in the case of the last calendar quarter prior to the expiration of the applicable indemnity coverage under this Agreement). Notwithstanding the foregoing, the Indemnified Party’s failure to provide notice under this Section 3.5 will not relieve the Indemnifying Party from liability hereunder with respect to such matter except in the event and only to the extent that the Indemnifying Party is materially prejudiced by such failure or delay.

(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification set forth in this Article III, including, without limitation, the selection of counsel (provided that if such claim involves Covered Environmental Losses, such counsel shall be reasonably acceptable to the Indemnified Party), determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent (which consent shall not be unreasonably withheld, conditioned or delayed) of the Indemnified Party unless it includes a full release of the Indemnified Party from such matter or issues, as the case may be.

(c) The Indemnified Party agrees to cooperate fully with the Indemnifying Party with respect to all aspects of the defense of any claims covered by the indemnification set forth in Article III, including, without limitation, the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the names of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and the making available to the Indemnifying Party of any employees of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to

maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 3.5. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article III; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party reasonably informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

(d) The indemnification obligations under this Article III shall continue with respect to any claim for indemnification pursuant to this Article III that is pending as of the end of the applicable survival period notwithstanding the expiration of such survival period.

5.4 Termination. This Agreement, other than the provisions set forth in Article III hereof, shall terminate upon a Change of Control of the General Partner or the MLP, other than any Change of Control of the General Partner or the MLP that may be deemed to have occurred pursuant to clause (iv) of the definition of Change of Control solely as a result of a Change of Control of Quicksilver.

5.6 Amendment or Modification. This Agreement may be amended or modified from time to time only by the written agreement of all the Parties; provided, however, that the MLP may not, without the prior approval of the Conflicts Committee, agree to any amendment or modification of this Agreement that, in the reasonable discretion of the General Partner, will have an adverse effect on the holders of Common Units. Each such instrument shall be reduced to writing and shall be designated on its face an “Amendment” or an “Addendum” to this Agreement.

5.7 Assignment; Third Party Beneficiaries. No Party shall have the right to assign its rights or obligations under this Agreement without the prior written consent of the other Parties. Each of the Parties hereto specifically intends that each entity comprising the Quicksilver Entities and the Partnership Entities, as applicable, whether or not a Party to this Agreement, shall be entitled to assert rights and remedies hereunder as third-party beneficiaries hereto with respect to those provisions of this Agreement affording a right, benefit or privilege to any such entity.

5.8 Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signatory Parties had signed the same document. All counterparts shall be construed together and shall constitute one and the same instrument.

5.9 Severability. If any provision of this Agreement or the application thereof to any Person or circumstance shall be held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

5.10 Gender, Parts, Articles and Sections. Whenever the context requires, the gender of all words used in this Agreement shall include the masculine, feminine and neuter, and the number of all words shall include the singular and plural.

consent or approval in its sole and uncontrolled discretion, with or without cause, and subject to such conditions as it shall deem appropriate.

5.13 Laws and Regulations. Notwithstanding any provision of this Agreement to the contrary, no Party shall be required to take any act, or fail to take any act, under this Agreement if the effect thereof would be to cause such Party to be in violation of any applicable law, statute, rule or regulation.

Except as set forth in Section 5.7, the provisions of this Agreement are enforceable solely by the Parties, and no limited partner, member, or assignee of Quicksilver or the MLP or other Person shall have the right, separate and apart from Quicksilver or the MLP, to enforce any provision of this Agreement or to compel any Party to comply with the terms of this Agreement.
