THE RIGHTS OFFERING

     2.1 The Rights Offering. Subject to Section 2.1(f), on the Rights Offering Launch Date, the Partnership will distribute to each holder of Common Units or General Partner Units, in respect of each Common Unit and General Partner Unit held by such holder, 0.35 Rights pursuant to and in accordance with the provisions of this Section 2.1. Such distribution, the related offering of securities for which the Rights are exercisable, and the issuance of such securities to the extent that the Rights are exercised (including those for which oversubscription privileges are exercised and also including the issuance of the Warrants), as more fully described in this Section 2.1, are referred to herein collectively as the “Rights Offering”.

          (a) Each whole right (a “Right”) will entitle the holder thereof to subscribe for and purchase from the Partnership one Common Unit for a subscription price of $2.50 per Common Unit (the “Right Subscription Price”) for which such holder’s Rights are exercised. No fractional Common Units will be issued pursuant to the Rights Offering; accordingly, any Person exercising Rights would be entitled to exercise for an aggregate number of Common Units that is rounded down to the nearest whole number. The Rights will be evidenced by one or more detachable subscription certificates (which may be evidenced by one global certificate) in form and substance reasonably acceptable to the Partnership and the NGP Parties.

          (b) The holders of Rights will be entitled to exercise such Rights from the Rights Offering Distribution Date until the Rights Offering Expiration Time.

          (c) The Rights Offering will include oversubscription privileges for each Person timely exercising Rights in full, which privilege will permit each such Person to purchase any Common Units, at the Right Subscription Price, for which Rights were exercisable but with respect to which Rights were not exercised, subject to a pro rata allotment (based on relative participation (i.e., number of Rights exercised) in the initial exercise of Rights) among all such Persons exercising such privilege.

          (d) In addition, the Partnership will issue to each Person exercising Rights (for no additional consideration) one Warrant in respect of each Common Unit purchased by such Person in the Rights Offering (including Common Units purchased pursuant to the

oversubscription privilege). The Warrants will be evidenced by one or more certificates (which may be evidenced by one global certificate) substantially in the form attached hereto as Exhibit E.

          (e) In connection with the Rights Offering, the Partnership will:

          (i) prepare a prospectus supplement to the base prospectus in the Registration Statement (the “Rights Offering Prospectus”) covering the Common Units for which the Rights are exercisable, the Warrants, and the Common Units for which the Warrants are exercisable;

          (ii) at least five Business Days before the Rights Offering Distribution Date, provide a copy of the Rights Offering Prospectus to the NGP Parties for review and comment;

          (iii) enter into a rights agent agreement with a bank or other intermediary, which agreement and such intermediary must be reasonably acceptable to both the Partnership and the NGP Parties, and which agreement will (among other things) appoint such intermediary as the rights agent (the “Rights Agent”) for the Rights Offering;

          (iv) enter into a warrant agent agreement with a bank or other intermediary including terms substantially similar to those set forth in Exhibit E, which agreement and such intermediary must be reasonably acceptable to both the Partnership and the NGP Parties, and which agreement will (among other things) appoint such intermediary as the warrant agent for the Warrants;

          (v) enter into such agreements with, and provide such instruments and documents to, NASDAQ, DTC and the Partnership’s transfer agent as are reasonably necessary or appropriate to consummate the Rights Offering; and

          (vi) use its best efforts to as promptly as practicable take any and all action necessary or appropriate to keep effective all registrations, permits, consents and approvals of the SEC and any other applicable Governmental Authorities, and make such filings under applicable Laws as are reasonably necessary or appropriate in connection with the Rights Offering; provided, that none of the foregoing requires the Partnership to disclose material non-public information regarding the Partnership Group if the Conflicts Committee determines in good faith that it is in the best interest of the Partnership not to disclose such information at such time and the Partnership is not otherwise required to disclose such information hereunder.

          (f) The obligations of the Partnership set forth in this Section 2.1 will be subject to the fulfillment (or the waiver by the Conflicts Committee on behalf of the Partnership, which may be granted or withheld in the Conflicts Committee’s sole discretion) of each condition precedent listed in this Section 2.1(f).

ARTICLE III
THE EQUITY OFFERING

     3.1 The Equity Offering. The Partnership will pursue, and use commercially reasonable efforts to market and complete, an Underwritten Public Offering pursuant to and in accordance with this Section 3.1 as soon as reasonably practicable after the completion of the Rights Offering but before the Offering Completion Deadline. In lieu of completing any such Underwritten Public Offering, the Partnership may elect to issue and sell by or before the Offering Completion Deadline Common Units in a public offering that does not constitute an Underwritten Public Offering, including any direct placement, “bought deal” or block trade pursuant to an effective registration statement or registration statement under the Securities Act, or in a private placement (any such offering being referred to as an “Alternative Offering” and collectively with any Underwritten Public Offering, an “Offering”) if the Conflicts Committee concludes in good faith that engaging in an Alternative Offering is in the best interests of the Partnership. Upon the consummation of any Offering, the Partnership shall be deemed to have satisfied its obligations under this Section 3.1. Notwithstanding anything to the contrary herein, the Partnership shall have no obligation to initiate marketing of (i.e., distribution of a prospectus or offering memorandum to potential investors), or complete, any Offering if the Conflicts Committee concludes in good faith that it is not in the best interests of the Partnership to do so. Other than (x) pursuant to employee benefit plans, qualified stock option plans or employee compensation plans and (y) as otherwise contemplated by this Agreement or the Transactions, the Partnership will not complete any Offering before the Offering Completion Deadline that does not comply with this Section 3.1.

          (a) The price to the public or ultimate purchaser in the Offering will be no less than $3.10 per Common Unit. If the price to the public or ultimate purchaser in the Offering is $3.40 per Common Unit or less, the gross proceeds of the Offering will not exceed $105 million (excluding any overallotment option). If the price to the public or

the ultimate purchaser in the Offering is greater than $3.40 per Common Unit, the gross proceeds of the Offering will not exceed $140 million (excluding any overallotment option).

          (b) The Conflicts Committee shall have the authority to determine on behalf of the Partnership the form of the Offering, the size of the Offering, the timing of the Offering, the price to be received in the Offering and the other material terms of the Offering. For the avoidance of doubt, the Partnership shall have no obligation to initiate marketing of (i.e., distribution of a prospectus or offering memorandum to potential investors), or complete, such Offering if the Conflicts Committee concludes in good faith that it is not in the best interests of the Partnership to initiate marketing of or complete such Offering.

          (c) In connection with any Offering, the Partnership will (as applicable):

          (i) prepare a prospectus supplement to the base prospectus in the Registration Statement or an offering memorandum (the “Offering Document”) covering the Common Units to be issued in the Offering;

          (ii) at least five Business Days before beginning marketing of the Offering, provide a draft of the Offering Document (if any) to the NGP Parties for reasonable review and comment;

          (iii) enter into an underwriting agreement or other purchase agreement, having reasonable and customary terms, with one or more underwriters, reasonably acceptable to the NGP Parties;

          (iv) enter into such agreements with, and provide such instruments and documents to, NASDAQ, DTC and the Partnership’s transfer agent as are reasonably necessary or appropriate to consummate the Offering; and

          (v) take any and all action necessary or reasonably appropriate to keep effective all registrations, permits, consents and approvals of the SEC and any other applicable Governmental Authorities, and make such filings under applicable Laws as are necessary or reasonably appropriate in connection with the Offering; provided, that none of the foregoing requires the Partnership to disclose material non-public information regarding the Partnership Group if the Conflicts Committee determines in good faith that it is in the best interest of the Partnership not to disclose such information at such time.

          (d) In connection with the Offering, the NGP Parties shall:

          (i) enter into a customary lock-up agreement regarding any securities of the Partnership held by such NGP Party, as reasonably requested by the lead underwriter or the applicable initial purchaser; and

          (ii) furnish to the Partnership for inclusion in any offering or disclosure document, information regarding the NGP Parties to the extent reasonably requested by the Partnership; provided, that, unless the Partnership is

required by Law to disclose such information in such offering or disclosure document, none of the foregoing requires the NGP Parties to disclose material non-public information regarding the NGP Parties if the NGP Parties determine reasonably and in good faith that it is in the best interest of the NGP Parties not to disclose such information at such time.

     3.2 The NGP Commitment. If, at any time, the Conflicts Committee determines in good faith that the Partnership (i) will not be able to complete the Offering (excluding any overallotment option) prior to the Offering Completion Deadline or (ii) will receive gross proceeds from the Offering (excluding any overallotment option) of less than $105 million (or, if the price to the public or ultimate purchaser in the Offering is greater than $3.40 per Common Unit, $140 million) prior to the Offering Completion Deadline, then the Conflicts Committee, in its sole discretion, may elect to exercise its option hereunder, and ERH shall be obligated to purchase Common Units as set forth in this Section 3.2.

          (a) The Partnership may deliver notice (the “Equity Commitment Exercise Notice”) to the NGP Parties at any time before the Offering Completion Deadline electing to exercise the Partnership’s rights under this Section 3.2.

          (b) If the Equity Commitment Exercise Notice is timely delivered, then subject to the satisfaction or waiver by the NGP Parties of the conditions set forth in Section 3.3, ERH will purchase from the Partnership, the Equity Commitment Amount at a price of $3.10 per Common Unit.

          (c) The purchase by ERH of Common Units pursuant to Section 3.2(b) will take place on the later of (A) the earlier of (i) the closing date of the Offering (excluding any overallotment option) and (ii) the Offering Completion Deadline and (B) if all conditions set forth in Section 3.3 are not satisfied or waived on the date described in clause (A), the first Business Day on which all of the conditions set forth in Section 3.3 have been satisfied or waived (the “Initial NGP Common Unit Purchase Date”); provided, however, that ERH shall not be required to purchase Common Units pursuant to Section 3.2(b) more than six months after the Offering Completion Deadline. In the event that the purchase by ERH of Common Units pursuant to Section 3.2(b) requires HSR Act approval, ERH shall purchase on the Initial NGP Common Unit Purchase Date the maximum amount of Common Units that may be purchased without HSR Act approval, and the Parties will thereafter cooperate and use commercially reasonable efforts to obtain such approval. As promptly as practicable following the receipt of such HSR Act approval and subject to the satisfaction of the conditions set forth in Section 3.3, ERH shall purchase any remaining Equity Commitment Amount at a price of $3.10 per Common Unit (the date of such purchase, the “Subsequent NGP Common Unit Purchase Date”). If HSR Act approval has not been obtained within six months after the Initial NGP Common Unit Purchase Date, the Parties will use commercially reasonable efforts in good faith to negotiate, or cause to be negotiated, a mutually satisfactory resolution to the remaining Equity Commitment Amount. If the Parties are unable to reach such mutually satisfactory resolution within six months after initiating negotiations pursuant to the immediately preceding sentence, then NGP shall have no further obligation under this Section 3.2 to purchase the remaining Equity Commitment Amount. Each of the Initial NGP Common Unit Purchase Date and each Subsequent NGP

Common Unit Purchase Date is referred to herein as an “NGP Common Unit Purchase Date”.

          (d) The Conflicts Committee shall have the sole authority and discretion to determine whether and when to deliver (or not deliver, as applicable) the Equity Commitment Exercise Notice.

          (e) The NGP Parties will deliver to the Partnership an officer’s certificate dated the NGP Common Unit Purchase Date to the effect that the representations and warranties of the NGP Parties set forth in Section 9.2 are true and correct in all material respects on the NGP Common Unit Purchase Date, as though made at and as of the NGP Common Unit Purchase Date.

          (f) The NGP Parties shall not take any action (other than actions required under this Agreement) with respect to any Common Units or Subordinated Units that would be reasonably likely (taken together with the transactions contemplated by this Agreement) to result in a HSR Act filing obligation.

     3.3 Conditions to the NGP Commitment. The obligation of ERH to purchase Common Units pursuant to Section 3.2 will be subject to the fulfillment (or the waiver by ERH, which may be granted or withheld in ERH’s sole discretion) of each condition precedent listed in this Section 3.3.

          (a) All conditions set forth in Section 8.1 have been fulfilled prior to the NGP Common Unit Purchase Date;

          (b) No Action is pending or threatened in writing that seeks to restrain or prohibit the consummation of, or otherwise challenges the legality or validity of, the consummation of ERH’s purchase of Common Units pursuant to Section 3.2;

          (c) No Order has been issued and is continuing that restrains or prohibits the consummation of ERH’s purchase of Common Units pursuant to Section 3.2;

          (d) The representations and warranties of the Partnership set forth in Section 9.1 are true and correct in all material respects on the NGP Common Unit Purchase Date, as though made at and as of the NGP Common Unit Purchase Date;

          (e) The Partnership has performed and complied in all material respects with all covenants and agreements contained in this Agreement that are required to be performed and complied with by the Partnership on or prior to the NGP Common Unit Purchase Date;

          (f) The Rights Offering has been completed and all outstanding Rights have been exercised or have expired;

          (h) The transactions contemplated by the R&M Purchase Agreement shall have closed.

          (c) No Action is pending or threatened in writing that seeks to restrain or prohibit the consummation of, or otherwise challenges the legality or validity of, the payment of the Transaction Fee pursuant to Section 4.1;

The Partnership will have a period of twenty-one (21) days after receipt of the Transaction Fee Allocation Schedule (the “Notice Period”) to notify ERH in writing of its election to accept or reject the Transaction Fee Allocation Schedule; provided, however, that any rejection must be reasonable. In the event written notice is received rejecting the Transaction Fee Allocation Schedule during the Notice Period, ERH and the Partnership shall attempt to resolve any disputes in good faith. If any dispute shall not have been resolved within thirty (30) days after the initial written notice of rejection is received by ERH, then the dispute shall, unless the parties otherwise agree, be submitted to and settled by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association, now in effect.

     7.2 The Proxy Statement and the Unitholder Meeting.

          (a) Eagle Rock GP, as general partner of the Partnership, will take, in accordance with applicable Law, NASDAQ rules and the Partnership Agreement, all action necessary to call, hold and convene an appropriate meeting of the holders of Common Units and Subordinated Units to consider and vote solely upon the Unitholder Proposals and any other matters required to be approved by them for consummation of the Transactions (including any adjournment or postponement as determined by the Conflicts Committee, the “Unitholder Meeting”) as promptly as reasonably practicable after the date hereof. The Board and the Conflicts Committee will recommend approval of the Unitholder Proposals (the “Recommendation”), and the Partnership will take all reasonable lawful action to solicit approval of the Unitholder Proposals by the holders of Common Units and by the holders of Subordinated Units. Notwithstanding the foregoing, at any time prior to obtaining the Required Unitholder Approvals, the Board and/or the Conflicts Committee may withdraw, modify or qualify in any manner adverse to the NGP Parties the Recommendation (any such action a “Change in Recommendation”) if the Board and/or the Conflicts Committee (as the case may be) has concluded in good faith, after consultation with its outside legal advisors and financial consultants, that the failure to make a Change in Recommendation would either not be in the best interests of the Partnership or in the best interests of the Non-Affiliated Unitholders; provided, however, that the Board and/or the Conflicts Committee shall not be entitled to exercise its rights to make a Change in Recommendation pursuant to this sentence unless the Partnership has provided to the NGP Parties five days prior written notice advising the NGP Parties that the Board and/or the Conflicts Committee intends to take such action and specifying the reasons therefor in reasonable detail, including, if applicable, the terms and conditions of any proposed transaction that is the basis of the proposed action. Any Change in Recommendation will not change the approval of the Unitholder Proposals or any other approval of the Board and the Conflicts Committee, including in any respect that would have the effect of causing any state (including Delaware) takeover statute or other similar statute to be applicable to the matters contemplated hereby.

          (b) As promptly as reasonably practicable after the date hereof, the Partnership will prepare and file with the SEC the Proxy Statement in preliminary form. The Parties will cooperate with each other in the preparation of the Proxy Statement; without limiting the generality of the foregoing, the NGP Parties will furnish to the Partnership the information relating to the NGP Parties required by the Exchange Act to be set forth in the Proxy Statement, and the NGP Parties and their counsel will be given the opportunity to review and comment on the Proxy Statement prior to the filing thereof with the SEC. The Partnership and the NGP Parties will each use its commercially reasonable efforts, after consultation with the other Parties, to respond promptly to any comments made by the SEC with respect to the Proxy Statement. The Partnership will use its commercially reasonable efforts to cause the Proxy Statement to be transmitted to the holders of Common Units and Subordinated Units as promptly as practicable following the filing thereof in definitive form with the SEC. The Partnership will advise

the NGP Parties promptly after it receives notice of any request by the SEC for amendment of the Proxy Statement or comments thereon and responses thereto or requests by the SEC for additional information. If at any time prior to the Unitholder Meeting any information relating to the Partnership or the NGP Parties, or any of their respective affiliates, officers or directors, should be discovered by the Partnership or any NGP Party that should be set forth in an amendment or supplement to the Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the Party which discovers such information will promptly notify the other Parties and an appropriate amendment or supplement describing such information will be promptly filed with the SEC and, to the extent required by Law, disseminated to the holders of Common Units and Subordinated Units. The Partnership will not mail any Proxy Statement, or any amendment or supplement thereto, with respect to which any NGP Party reasonably objects to disclosure therein specifically regarding any NGP Party or any representative of any NGP Party (including members of the Board appointed, pursuant to the terms of the Partnership Agreement, by the NGP Representative (as defined therein)).

          (c) Once the Unitholder Meeting has been called and noticed, the Partnership will not postpone or adjourn the Unitholder Meeting past the Termination Date without the consent of the NGP Parties, which consent will not be unreasonably withheld or delayed, other than (i) for the absence of a quorum or (ii) to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure that the Partnership believes in good faith is necessary under applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by the holders of Common Units and Subordinated Units prior to the Unitholder Meeting; provided that if the Unitholder Meeting is so delayed to a date after the Termination Date as a result of either (i) or (ii) above, then the Termination Date will be extended to the seventh Business Day after such date.

          (d) Each of the NGP Parties hereby irrevocably and unconditionally agrees that from and after the date hereof and until the earlier of (i) the first Business Day after the Unitholder Approval Date or (ii) the date this Agreement is terminated in accordance with its terms (the “Expiration Time”), at any Unitholders’ Meeting, such NGP Party will, unless the Partnership directs the NGP Parties to do otherwise, (A) appear at such Unitholders’ Meeting or otherwise cause the Common Units and Subordinated Units beneficially owned by such NGP Party as of the relevant time (“Owned Units”) to be counted as present for purposes of calculating a quorum and respond to any other request by the Partnership for written consent, if any, and, (B) vote, or cause to be voted, all of its Owned Units (1) in favor of the approval of the Unitholder Proposals (whether or not recommended by the Board or the Conflicts Committee), (2) in favor of the approval of proposals made by the Partnership or the Conflicts Committee for an adjournment of the Unitholders’ Meeting, and (3) against any action or agreement that would reasonably be expected to (a) result in a breach of any representation, warranty or covenant of any NGP Party under this Agreement or (b) interfere with, delay or attempt to discourage the consummation of the Transactions.

          (e) Each of the NGP Parties hereby agrees, while this Agreement is in effect, promptly to notify the Partnership of the number of any new Common Units with respect to which beneficial ownership is acquired by such NGP Party, if any, after the date hereof and before the Expiration Time. Any such Common Units shall automatically become subject to the terms of this Agreement as Owned Units as though beneficially owned by such NGP Party as of the date hereof.

          (f) Except as provided for herein, the NGP Parties agree, from the date hereof until the Expiration Time, not to (i) directly or indirectly transfer or offer to transfer any Owned Units; (ii) tender any Owned Units into any tender or exchange offer or otherwise; or (iii) otherwise restrict the ability of the NGP Parties to freely exercise all voting rights with respect to the Owned Units. Any action attempted to be taken in violation of the preceding sentence will be null and void.

          (g) The Conflicts Committee shall have the sole authority to act on behalf of the Partnership with respect to the matters set forth in Sections 7.2(d), 7.2(e) and 7.2(f).

          (h) Notwithstanding anything to the contrary in this Agreement, no approval of any Unitholder Proposal will be sought, and no such Unitholder Meeting will be held, if the R&M Purchase Agreement has terminated.

     7.3 Further Assurances. Subject to the terms and conditions of this Agreement, each Party will use commercially reasonable efforts in good faith to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper, desirable or advisable under applicable Laws, so as to enable consummation of the matters contemplated hereby, including obtaining (and cooperating with the other Parties to obtain) HSR Act approval, if required, or the expiration or early termination of any applicable waiting period thereunder, and any other third party approval that is required to be obtained by the Party in connection with the Transactions and the other matters contemplated by this Agreement and the R&M Purchase Agreement, and using commercially reasonable efforts to lift or rescind any injunction or restraining order or other order adversely affecting the ability of the Parties to consummate the matters contemplated hereby, and using commercially reasonable efforts to defend any litigation seeking to enjoin, prevent or delay the consummation of the matters contemplated hereby or seeking material damages, and each Party will cooperate fully with the other Parties to that end, and will furnish to the other Parties copies of all correspondence, filings and communications between it and its Affiliates, on the one hand, and any Governmental Authority, on the other hand, with respect to the matters contemplated hereby. In complying with the foregoing, the Partnership shall not be required to take any action that is reasonably likely to result in a Material Adverse Effect.

     7.4 Press Releases. No Party will, without the prior approval of the Conflicts Committee in the case of any NGP Party and the NGP Parties in the case of the Partnership, issue any press release or written statement for general circulation relating to the matters contemplated hereby, except as otherwise required by applicable Law or regulation or the rules of the NASDAQ, in which case it will consult with the other applicable Party before issuing any such press release or written statement.

     (iv) there has been a material breach of or any inaccuracy in any of the representations or warranties set forth in this Agreement on the part of the other party (treating the NGP Parties as one party for the purposes of this Section 10.1(b)(iv)), which breach is not cured within 30 days following receipt by the breaching party of written notice of such breach from the terminating party, or which breach, by its nature, cannot be cured prior to the Transaction Fee Payment Date (provided in any such case that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein); or

     (v) there has been a material breach of any of the covenants or agreements set forth in this Agreement on the part of the other party (treating the NGP Parties as one party for the purposes of this Section 10.1(b)(v)), which breach has not been cured within 30 days following receipt by the breaching party of written notice of such breach from the terminating party, or which breach, by its nature, cannot be cured prior to the Transaction Fee Payment Date (provided in any such case that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein);

  10.2 Effect of Termination.

     (a) If this Agreement is terminated as provided in Section 10.1, the terminating Party will promptly give written notice thereof to the other Parties specifying the provision of this Agreement pursuant to which such termination is made, and this Agreement will be null and void and, except as provided in Sections 10.2 and 11.1 or as otherwise expressly provided herein, no Party will have any rights or obligations under this Agreement, except that no such termination will relieve any Party from liability for damages for any willful and material breach of any agreement or covenant contained herein.

If the R&M Purchase Agreement is terminated by Black Stone because either the Partnership or any of its Affiliates breached any representation, warranty or covenant in the R&M Purchase Agreement, then the Partnership will pay to ERH, within five Business Days after such termination, the Termination Fee. Notwithstanding anything to the contrary in this Agreement, the Parties agree that in circumstances where payment of the Termination Fee is required hereunder, upon such payment, the payment of any Termination Fee in accordance with this Section 10.2 shall be the exclusive remedy of the NGP Parties for (i) any loss suffered as a result of the failure of the Transactions to be consummated and (ii) any other losses, damages, obligations or liabilities suffered as a result of or under this Agreement and the Transactions.

Exhibit A

Form of Partnership Agreement Amendment

Exhibit A

AMENDMENT NO. 1 TO

FIRST AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP

OF

EAGLE ROCK ENERGY PARTNERS, L.P.

     THIS AMENDMENT NO. 1 TO THE FIRST AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF EAGLE ROCK ENERGY PARTNERS, L.P. dated as of [                    ], 2010 (this “Amendment No. 1”), is entered into by and among Eagle Rock Energy GP, L.P., a Delaware limited partnership, as the General Partner and as the lawful attorney-in-fact for the Limited Partners, together with any other Persons who become Partners in the Partnership or parties hereto as provided herein.

     WHEREAS, the General Partner and Limited Partners entered into the First Amended and Restated Agreement of Limited Partnership of Eagle Rock Energy Partners, L.P. on October 27, 2006 (the “First Amended and Restated Agreement”);

     WHEREAS, the Partnership has entered into the Securities Purchase and Global Transaction Agreement, dated December 21, 2009, among the Partnership and the other parties thereto, which contemplates, among other things, the distribution of rights and the issuance of warrants by the Partnership; and

     WHEREAS, this Amendment No. 1 has been approved by a Unit Majority and the General Partner.

     NOW, THEREFORE, pursuant to Section 13.2 of the First Amended and Restated Agreement, in consideration of the covenants, conditions and agreements contained herein, the First Amended and Restated Agreement is hereby amended as follows:

     Section 1. Amendment.

     (a) Section 1.1 is hereby amended to add the following definitions:

     (i) “Right Exercised Common Unit” means any Common Unit issued by the Partnership upon the exercise of a right to purchase a Common Unit.

     (ii) “Warrant Exercised Common Unit” means any Common Unit issued by the Partnership upon the exercise of a warrant to purchase a Common Unit.

     (b) Section 5.5(a) is hereby amended and restated in its entirety as follows:

     The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner)

owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv) and Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Partnership with respect to such Partnership Interest and (ii) all items of Partnership income and gain (including income and gain exempt from tax) computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property made with respect to such Partnership Interest and (y) all items of Partnership deduction and loss computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1. The Partnership shall follow the proposed noncompensatory option regulations under Proposed Treasury Regulation Sections 1.704-1, 1.721-2 and 1.761-3 at all times, including when the assets of the Partnership are revalued or any warrant is exercised in accordance with its terms.

     (c) Section 5.5(d) is hereby amended and restated in its entirety as follows:

     (i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of Partnership Interests as consideration for the provision of services or the conversion of the General Partner’s Combined Interest to Common Units pursuant to Section 11.3(b), the Capital Account of all Partners and the Carrying Value of each Partnership property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such issuance. In accordance with Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(2), upon any exercise of a warrant, the Capital Account of all Partners and the Carrying Value of each Partnership property shall immediately after such exercise be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such exercise. Any Unrealized Gain or Unrealized Loss (or items thereof) shall first be allocated to the Partners who were the initial holders of a Warrant Exercised Common Unit until the Capital Account in respect of each such Warrant Exercised Common Unit is equal to the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Warrant Exercised Common Unit) if the operation of this sentence is triggered by the exercise of a warrant, and regardless of whether the operation of this sentence is triggered by the exercise of a warrant, any remaining Unrealized Gain or Unrealized Loss shall be allocated among the Partners pursuant to Section 6.1(c) in the same manner as any item of gain or loss actually recognized following an event giving rise to the dissolution of the Partnership would have been allocated. If the Unrealized Gain or

Unrealized Loss allocated as a result of the exercise of a warrant is not sufficient to cause the Capital Account of each Warrant Exercised Common Unit to equal the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Warrant Exercised Common Unit), then Capital Account balances shall be reallocated between the Partners holding Warrant Exercised Common Units and the Partners holding Common Units (other than Warrant Exercised Common Units) so as to cause the Capital Account of each Warrant Exercised Common Unit to equal the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Warrant Exercised Common Unit), in accordance with Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3). In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership assets (including cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests, or immediately after the exercise of a warrant, shall be determined by the General Partner using such method of valuation as it may adopt; provided, however, that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners at such time. The General Partner shall allocate such aggregate value among the assets of the Partnership (in such manner as it determines) to arrive at a fair market value for individual properties.

     (ii) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Capital Accounts of all Partners and the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized in a sale of such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated to the Partners, at such time, pursuant to Section 6.1(c) in the same manner as any item of gain or loss actually recognized during such period would have been allocated. In determining such Unrealized Gain or Unrealized Loss the aggregate cash amount and fair market value of all Partnership assets (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of an actual distribution that is not made pursuant to Section 12.4 or in the case of a deemed distribution, be determined and allocated in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined and allocated by the Liquidator using such method of valuation as it may adopt.

     (d) Section 5.9 is hereby amended and restated in its entirety as follows:

     Splits, Combinations and Other Pro Rata Distributions.

     (a) Subject to Section 5.9(d), Section 6.6 and Section 6.9 (dealing with adjustments of distribution levels), the Partnership may make a Pro Rata distribution of Partnership Securities and any options, rights, warrants or

appreciation rights relating to any Partnership Security to all Record Holders or may effect a subdivision or combination of Partnership Securities so long as, after any such event (but before giving effect to the exercise of any options, rights, warrants or appreciation rights relating to any Partnership Securities distributed in connection with such event), each Partner shall have the same Percentage Interest in the Partnership as before such event, and any amounts calculated on a per Unit basis (including any Common Unit Arrearage or Cumulative Common Unit Arrearage) or stated as a number of Units (including the number of Subordinated Units that may convert prior to the end of the Subordination Period) are proportionately adjusted.

     (b) Whenever such a distribution, subdivision or combination of Partnership Securities or any options, rights, warrants or appreciation rights relating to any Partnership Securities is declared, the General Partner shall select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of such notice. The General Partner also may cause a firm of independent public accountants selected by it to calculate the number of Partnership Securities or any options, rights, warrants or appreciation rights relating to any Partnership Securities to be held by each Record Holder after giving effect to such distribution, subdivision or combination. The General Partner shall be entitled to rely on any certificate provided by such firm as conclusive evidence of the accuracy of such calculation.

     (c) Promptly following any such distribution, subdivision or combination, the Partnership may issue Certificates to the Record Holders of Partnership Securities as of the applicable Record Date representing the new number of Partnership Securities held by such Record Holders, or the General Partner may adopt such other procedures that it determines to be necessary or appropriate to reflect such changes. If any such combination results in a smaller total number of Partnership Securities Outstanding, the Partnership shall require, as a condition to the delivery to a Record Holder of such new Certificate, the surrender of any Certificate held by such Record Holder immediately prior to such Record Date.

     (d) The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions of this Section 5.9(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit).

     (e) Section 6.1(e)(x) is hereby amended and restated in its entirety as follows:

     Economic Uniformity. (A) At the election of the General Partner with respect to any taxable period ending upon, or after, the termination of the Subordination Period, all or a portion of the remaining items of Partnership

income or gain for such taxable period, after taking into account allocations pursuant to Section 6.1(d)(iii), shall be allocated 100% to each Partner holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (“Final Subordinated Units”) in the proportion of the number of Final Subordinated Units held by such Partner to the total number of Final Subordinated Units then Outstanding, until each such Partner has been allocated an amount of income or gain that increases the Capital Account maintained with respect to such Final Subordinated Units to an amount equal to the product of (A) the number of Final Subordinated Units held by such Partner and (B) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Final Subordinated Units and the Capital Accounts underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of such Final Subordinated Units into Common Units. This allocation method for establishing such economic uniformity will be available to the General Partner only if the method for allocating the Capital Account maintained with respect to the Subordinated Units between the transferred and retained Subordinated Units pursuant to Section 5.5(c)(ii) does not otherwise provide such economic uniformity to the Final Subordinated Units.

     (B) With respect to any taxable period ending after a right is exercised, all or a portion of the remaining items of Partnership gross income or gain for such taxable period shall be allocated 100% to each Partner who was the initial holder of a Right Exercised Common Unit until each such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such Right Exercised Common Units to an amount equal to the product of (A) the number of Right Exercised Common Units held by such Partner and (B) the Per Unit Capital Amount for a Common Unit (other than a Right Exercised Common Unit).

     (f) Section 6.2(c) is hereby amended and restated in its entirety as follows:

     For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions, (ii) make special allocations for federal income tax purposes of income (including gross income), gains, losses, deductions, Unrealized Gains or Unrealized Losses, and (iii) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code (including, if necessary to accomplish the intent of this Agreement, the finalization of Treasury Regulations that may differ from the Proposed Treasury Regulations relied upon in Section 5.5(d)(i) and Section 6.2(i) hereof) or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.2(c) only if such

conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Limited Partner Interests issued and Outstanding or the Partnership, and if such allocations are consistent with the principles of Section 704 of the Code.

     (g) Section 6.2 is hereby amended to add the following as Section 6.2(i) immediately following Section 6.2(h):

     If Capital Account balances are reallocated between the Partners in accordance with Section 5.5(d)(i) hereof and Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(4), beginning with the year of reallocation and continuing until the allocations required are fully taken into account, the Partnership shall make corrective allocations (allocations of items of gross income or gain or loss or deduction for federal income tax purposes that do not have a corresponding book allocation) to take into account the Capital Account reallocation, as provided in Proposed Treasury Regulation Section 1.704-1(b)(4)(x).

     Section 2. Defined Terms. Capitalized terms used in this Amendment No. 1 but not otherwise defined shall have the meaning assigned to such terms in the First Amended and Restated Agreement.

     Section 3. General Authority. The appropriate officers of the General Partner are hereby authorized to make such further clarifying and conforming changes to the Partnership Agreement as they deem necessary or appropriate, and to interpret the Partnership Agreement, to give effect to the intent and purpose of this Amendment No. 1.

     Section 4. Ratification of Partnership Agreement. Except as expressly modified and amended herein, all of the terms and conditions of the First Amended and Restated Agreement shall remain in full force and effect.

     Section 5. Governing Law. This Amendment No. 1 will be governed by and construed in accordance with the laws of the State of Delaware.

     (c) Except as provided in Section 13.4(c)(v), nothing contained in this Agreement shall be construed to prevent a disposition by any stockholder, member, partner or other owner of the General Partner of any or all of the shares of stock, membership interests, partnership interests or other ownership interests in the General Partner.

     Section 4.5 Registration and Transfer of Limited Partner Interests.

     (a) The General Partner shall keep or cause to be kept on behalf of the Partnership a register in which, subject to such reasonable regulations as it may prescribe and subject to the provisions of Section 4.5(b), the Partnership will provide for the registration and transfer of Limited Partner Interests. The Transfer Agent is hereby appointed registrar and transfer agent for the purpose of registering Common Units and transfers of such Common Units as herein provided. The Partnership shall not recognize transfers of Certificates evidencing Limited Partner Interests unless such transfers are effected in the manner described in this Section 4.5. Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions of Section 4.5(b), the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Common Units, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered.

     (b) Except as otherwise provided in Section 4.9, the General Partner shall not recognize any transfer of Limited Partner Interests until the Certificates evidencing such Limited Partner Interests are surrendered for registration of transfer. No charge shall be imposed by the General Partner for such transfer; provided, that as a condition to the issuance of any new Certificate under this Section 4.5, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto.

     (c) Subject to (i) the provisions of this Section 4.5, (ii) Section 4.3, (iii) Section 4.8, (iv) with respect to any class or series of Limited Partner Interests, the provisions of any statement of designations or an amendment to this Agreement establishing such class or series, (v) any contractual provisions binding on any Limited Partner and (vi) provisions of applicable law including the Securities Act, Limited Partner Interests shall be freely transferable.

     (d) Subject to Section 4.5(e), the General Partner and its Affiliates shall have the right at any time to transfer their Common Units to one or more Persons.

     (e) Except as may be sold in a Broadly Distributed Underwritten Public Offering or in any transaction or series of related transactions in which all holders of Partnership Securities share in the Premium (as defined below) Pro Rata, during the NGP Restriction Period, the NGP Parties (individually or collectively) may not, without the prior approval of the Conflicts Committee, sell 5.0% or more of the Outstanding Partnership Securities of any class in any

transaction or series of related transactions for a sales price that exceeds by 5.0% or more the greater of (A) the Current Market Price and (B) the Closing Price on the immediately preceding Trading Day, in each case, as of the date on which any of the NGP Parties enters into an agreement to sell any such Partnership Securities (such excess, the “Premium”). For the purposes of this Section 4.5(e), (i) the term “Broadly Distributed Underwritten Public Offering” means a firm commitment underwritten public offering whereby no purchaser or group of affiliated purchasers is sold 5.0% or more of the Outstanding Partnership Securities of any class and (ii) the term “Outstanding Partnership Securities” shall be deemed to include Partnership Securities that may be issued in respect of warrants outstanding calculated on a net diluted basis using the treasury stock method.

     Section 4.6 Transfer of the General Partner’s General Partner Interest.

     (a) Subject to Section 4.6(c) and Section 4.6(d) below, prior to September 30, 2016, the General Partner shall not transfer all or any part of its General Partner Interest (represented by General Partner Units) to a Person unless such transfer (i) has been approved by the prior written consent or vote of the holders of at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) or (ii) is of all, but not less than all, of its General Partner Interest to (A) an Affiliate of the General Partner (other than an individual) or (B) another Person (other than an individual) in connection with the merger or consolidation of the General Partner with or into such other Person or the transfer by the General Partner of all or substantially all of its assets to such other Person.

     (b) Subject to Section 4.6(c) and Section 4.6(d) below, on or after September 30, 2016, the General Partner may transfer all or any of its General Partner Interest without Unitholder approval.

     (c) Notwithstanding anything herein to the contrary, no transfer by the General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and to be bound by the provisions of this Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner under the Delaware Act or cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate portion thereof, if applicable) of the partnership or membership interest of the General Partner as the general partner or managing member, if any, of each other Group Member. In the case of a transfer pursuant to and in compliance with this Section 4.6, the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.3, be admitted to the Partnership as the General Partner immediately prior to the transfer of the General Partner Interest, and the business of the Partnership shall continue without dissolution.

     (d) Following the consummation of GP Acquisition, (i) the General Partner shall not transfer all or any part of its General Partner Interest or otherwise delegate the power and authority to manage and control the business and affairs of the Partnership to any Person and (ii)

so long as the Partnership is a limited partnership, the General Partner shall remain a direct or indirect wholly-owned Subsidiary of the Partnership.

     Section 4.7 [Reserved.]

     Section 4.8 Restrictions on Transfers.

     (a) Except as provided in Section 4.8(d) below, but notwithstanding the other provisions of this Article IV, no transfer of any Partnership Interests shall be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such transfer, (ii) terminate the existence or qualification of the Partnership under the laws of the jurisdiction of its formation, or (iii) cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed).

     (b) The General Partner may impose restrictions on the transfer of Partnership Interests if it receives an Opinion of Counsel that such restrictions are necessary to avoid a significant risk of the Partnership becoming taxable as a corporation or otherwise becoming taxable as an entity for federal income tax purposes. The General Partner may impose such restrictions by amending this Agreement; provided, however, that any amendment that would result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then listed or admitted to trading must be approved, prior to such amendment being effected, by the holders of at least a majority of the Outstanding Limited Partner Interests of such class.

     (c) [Reserved.]

     (d) Nothing contained in this Article IV, or elsewhere in this Agreement, shall preclude the settlement of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading.

     (e) Each certificate evidencing Partnership Interests shall bear a conspicuous legend in substantially the following form:

THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF EAGLE ROCK ENERGY PARTNERS, L.P. THAT THIS SECURITY MAY NOT BE SOLD, OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED IF SUCH TRANSFER WOULD (A) VIOLATE THE THEN APPLICABLE FEDERAL OR STATE SECURITIES LAWS OR RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER GOVERNMENTAL AUTHORITY WITH JURISDICTION OVER SUCH TRANSFER, (B) TERMINATE THE EXISTENCE OR QUALIFICATION OF EAGLE ROCK ENERGY PARTNERS, L.P. UNDER THE LAWS OF THE STATE OF DELAWARE, OR (C) CAUSE EAGLE ROCK ENERGY PARTNERS, L.P. TO BE TREATED AS AN ASSOCIATION TAXABLE AS A

CORPORATION OR OTHERWISE TO BE TAXED AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES (TO THE EXTENT NOT ALREADY SO TREATED OR TAXED). EAGLE ROCK ENERGY GP L.P., THE GENERAL PARTNER OF EAGLE ROCK ENERGY PARTNERS, L.P., MAY IMPOSE ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO AVOID A SIGNIFICANT RISK OF EAGLE ROCK ENERGY PARTNERS, L.P. BECOMING TAXABLE AS A CORPORATION OR OTHERWISE BECOMING TAXABLE AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES. THE RESTRICTIONS SET FORTH ABOVE SHALL NOT PRECLUDE THE SETTLEMENT OF ANY TRANSACTIONS INVOLVING THIS SECURITY ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY IS LISTED OR ADMITTED TO TRADING.

     Section 4.9 Citizenship Certificates; Non-citizen Assignees.

     (a) If any Group Member is or becomes subject to any federal, state or local law or regulation that the General Partner determines would create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of a Limited Partner, the General Partner may request any Limited Partner to furnish to the General Partner, within 30 days after receipt of such request, an executed Citizenship Certification or such other information concerning his nationality, citizenship or other related status (or, if the Limited Partner is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) as the General Partner may request. If a Limited Partner fails to furnish to the General Partner within the aforementioned 30-day period such Citizenship Certification or other requested information or if upon receipt of such Citizenship Certification or other requested information the General Partner determines that a Limited Partner is not an Eligible Citizen, the Limited Partner Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.10. In addition, the General Partner may require that the status of any such Limited Partner be changed to that of a Non-citizen Assignee and, thereupon, the General Partner shall be substituted for such Non- citizen Assignee as the Limited Partner in respect of the Non-citizen Assignee’s Limited Partner Interests.

     (b) The General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Non-citizen Assignees, distribute the votes in the same ratios as the votes of Partners (including the General Partner) in respect of Limited Partner Interests other than those of Non-citizen Assignees are cast, either for, against or abstaining as to the matter.

     (c) Upon dissolution of the Partnership, a Non-citizen Assignee shall have no right to receive a distribution in kind pursuant to Section 12.4 but shall be entitled to the cash equivalent thereof, and the Partnership shall provide cash in exchange for an assignment of the Non-citizen Assignee’s share of any distribution in kind. Such payment and assignment shall be treated for Partnership purposes as a purchase by the Partnership from the Non-citizen Assignee of his Limited Partner Interest (representing his right to receive his share of such distribution in kind).

     (d) At any time after he can and does certify that he has become an Eligible Citizen, a Non-citizen Assignee may, upon application to the General Partner, request that with respect to any Limited Partner Interests of such Non-citizen Assignee not redeemed pursuant to Section 4.10, such Non-citizen Assignee be admitted as a Limited Partner, and upon approval of the General Partner, such Non-citizen Assignee shall be admitted as a Limited Partner and shall no longer constitute a Non-citizen Assignee and the General Partner shall cease to be deemed to be the Limited Partner in respect of the Non-citizen Assignee’s Limited Partner Interests.

     Section 4.10 Redemption of Partnership Interests of Non-citizen Assignees.

     (a) If at any time a Limited Partner fails to furnish a Citizenship Certification or other information requested within the 30-day period specified in Section 4.9(a), or if upon receipt of such Citizenship Certification or other information the General Partner determines, with the advice of counsel, that a Limited Partner is not an Eligible Citizen, the Partnership may, unless the Limited Partner establishes to the satisfaction of the General Partner that such Limited Partner is an Eligible Citizen or has transferred his Partnership Interests to a Person who is an Eligible Citizen and who furnishes a Citizenship Certification to the General Partner prior to the date fixed for redemption as provided below, redeem the Limited Partner Interest of such Limited Partner as follows:

     (i) The General Partner shall, not later than the 30th day before the date fixed for redemption, give notice of redemption to the Limited Partner, at his last address designated on the records of the Partnership or the Transfer Agent, by registered or certified mail, postage prepaid. The notice shall be deemed to have been given when so mailed. The notice shall specify the Redeemable Interests, the date fixed for redemption, the place of payment, that payment of the redemption price will be made upon surrender of the Certificate evidencing the Redeemable Interests and that on and after the date fixed for redemption no further allocations or distributions to which the Limited Partner would otherwise be entitled in respect of the Redeemable Interests will accrue or be made.

     (ii) The aggregate redemption price for Redeemable Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Limited Partner Interests of the class to be so redeemed multiplied by the number of Limited Partner Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, as determined by the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 5% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date.

     (iii) Upon surrender by or on behalf of the Limited Partner, at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank, the Limited Partner or his duly authorized representative shall be entitled to receive the payment therefor.

     (iv) After the redemption date, Redeemable Interests shall no longer constitute issued and Outstanding Limited Partner Interests.

     (b) The provisions of this Section 4.10 shall also be applicable to Limited Partner Interests held by a Limited Partner as nominee of a Person determined to be other than an Eligible Citizen.

     (c) Nothing in this Section 4.10 shall prevent the recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner that he is an Eligible Citizen. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date.

     Section 4.11 Special Provisions Relating to Holders of NGP Common Units. A Unitholder holding an NGP Common Unit shall be required to provide notice to the General Partner of the transfer of the NGP Common Unit within the earlier of (i) thirty (30) days following such transfer and (ii) the last Business Day of the calendar year during which such transfer occurred, unless (x) the transfer is to an Affiliate of such Unitholder (in which case such transferring Unitholder shall take all actions necessary to cause such Affiliate to be bound by the terms of this Section 4.11) or (y) by virtue of the application of Section 6.1(e)(x)(B) and (C), the General Partner has previously determined, based on advice of counsel, that the NGP Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics of Outstanding Common Units held by unrelated third party Unitholders. In connection with the condition imposed by this Section 4.11, the General Partner shall take whatever steps are required to provide economic uniformity to the NGP Common Units in preparation for a transfer of such Units; provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units that are not NGP Common Units.

ARTICLE V
CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS

     Section 5.1 Cancellation of Subordinated Units and Incentive Distribution Rights. On the date hereof, simultaneously with the effectiveness of this Agreement (a) pursuant to a contribution agreement contemplated by the Transaction Agreement, the General Partner and its Affiliates transferred all outstanding Subordinated Units and the Incentive Distribution Rights to the Partnership and (b) the Partnership cancelled such Subordinated Units and Incentive Distribution Rights; such actions being hereby approved and ratified notwithstanding any provision of the First Amended and Restated Agreement.

     Section 5.2 General Partner Interest; Additional Contributions by the General Partner.

     (a) Upon consummation of the GP Acquisition, (i) all economic rights with respect to the Partnership of the General Partner Interest, and the General Partner Units representing the General Partner Interest, including any and all rights to be allocated income, gains, losses and

deductions of the Partnership and to receive distributions made by the Partnership in respect of the General Partner Interest, shall automatically terminate notwithstanding Section 4.6 or any other provision of this Agreement and (ii) the Percentage Interest with respect to the General Partner Units shall automatically be reduced to zero, in each case, without further action by the Partnership or the General Partner. Following the GP Acquisition, the General Partner Interest shall continue to represent a non-economic general partner interest in the Partnership and the General Partner shall continue as the general partner of the Partnership and the Partnership will continue without dissolution.

     (b) Prior to the consummation of the GP Acquisition, upon the issuance of any additional Limited Partner Interests by the Partnership the General Partner may, in exchange for a proportionate number of General Partner Units, make additional Capital Contributions in an amount equal to the product obtained by multiplying (i) the quotient determined by dividing (A) the General Partner’s Percentage Interest by (B) 100 less the General Partner’s Percentage Interest times (ii) the amount contributed to the Partnership by the Limited Partners in exchange for such additional Limited Partner Interests. Except as set forth in Article XII, the General Partner shall not be obligated to make any additional Capital Contributions to the Partnership.

     Section 5.3 [Reserved.]

     Section 5.4 Interest and Withdrawal. No interest shall be paid by the Partnership on Capital Contributions. No Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon termination of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital Contributions or as to profits, losses or distributions. Any such return shall be a compromise to which all Partners agree within the meaning of Section 17-502(b) of the Delaware Act.

     Section 5.5 Capital Accounts.

     (a) The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest (other than the non-economic General Partner Interest of the General Partner following the GP Acquisition) a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv) and Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Partnership with respect to such Partnership Interest and (ii) all items of Partnership income and gain (including income and gain exempt from tax) computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property made with respect to such Partnership Interest and (y) all items of Partnership deduction and loss computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1. The Partnership shall follow the proposed noncompensatory option regulations under Proposed Treasury Regulation

Sections 1.704-1, 1.721-2 and 1.761-3 at all times, including when the assets of the Partnership are revalued or any warrant is exercised in accordance with its terms.

     (b) For purposes of computing the amount of any item of income, gain, loss or deduction which is to be allocated pursuant to Article VI and is to be reflected in the Partners’ Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose), provided, that:

     (i) Solely for purposes of this Section 5.5, the Partnership shall be treated as owning directly its proportionate share (as determined by the General Partner based upon the provisions of the applicable Group Member Agreement or governing, organizational or similar documents) of all property owned by (x) any other Group Member that is classified as a partnership for federal income tax purposes and (y) any other partnership, limited liability company, unincorporated business or other entity classified as a partnership for federal income tax purposes of which a Group Member is, directly or indirectly, a partner.

     (ii) All fees and other expenses incurred by the Partnership to promote the sale of (or to sell) a Partnership Interest that can neither be deducted nor amortized under Section 709 of the Code, if any, shall, for purposes of Capital Account maintenance, be treated as an item of deduction at the time such fees and other expenses are incurred and shall be allocated among the Partners pursuant to Section 6.1.

     (iii) Except as otherwise provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code which may be made by the Partnership and, as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for federal income tax purposes. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

     (iv) Any income, gain or loss attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Partnership’s Carrying Value with respect to such property as of such date.

     (v) In accordance with the requirements of Section 704(b) of the Code, any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Partnership were equal to the Agreed Value of such property. Upon an adjustment pursuant to Section 5.5(d) to the Carrying Value of any Partnership property

subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization attributable to such property shall be determined as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment.

     (vi) If the Partnership’s adjusted basis in a depreciable or cost recovery property is reduced for federal income tax purposes pursuant to Section 48(q)(1) or 48(q)(3) of the Code, the amount of such reduction shall, solely for purposes hereof, be deemed to be an additional depreciation or cost recovery deduction in the year such property is placed in service and shall be allocated among the Partners pursuant to Section 6.1. Any restoration of such basis pursuant to Section 48(q)(2) of the Code shall, to the extent possible, be allocated in the same manner to the Partners to whom such deemed deduction was allocated.

     (c) A transferee of a Partnership Interest shall succeed to a pro rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred.

     (d) (i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of Partnership Interests as consideration for the provision of services or the conversion of the General Partner’s Combined Interest to Common Units pursuant to Section 11.3(b), the Capital Account of all Partners and the Carrying Value of each Partnership property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such issuance. In accordance with Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(2), upon any exercise of a warrant, the Capital Account of all Partners and the Carrying Value of each Partnership property shall immediately after such exercise be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such exercise. Any Unrealized Gain or Unrealized Loss (or items thereof) shall first be allocated to the Partners who were the initial holders of a Warrant Exercised Common Unit until the Capital Account in respect of each such Warrant Exercised Common Unit is equal to the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Warrant Exercised Common Unit) if the operation of this sentence is triggered by the exercise of a warrant, and regardless of whether the operation of this sentence is triggered by the exercise of a warrant, any remaining Unrealized Gain or Unrealized Loss shall be allocated among the Partners pursuant to Section 6.1(c) in the same manner as any item of gain or loss actually recognized following an event giving rise to the dissolution of the Partnership would have been allocated. If the Unrealized Gain or Unrealized Loss allocated as a result of the exercise of a warrant is not sufficient to cause the Capital Account of each Warrant Exercised Common Unit to equal the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Warrant Exercised Common Unit), then Capital Account balances shall be reallocated between the Partners holding Warrant Exercised Common Units and the Partners holding Common Units (other than Warrant Exercised Common Units) so as to cause the Capital

Account of each Warrant Exercised Common Unit to equal the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Warrant Exercised Common Unit), in accordance with Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3). In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership assets (including cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests, or immediately after the exercise of a warrant, shall be determined by the General Partner using such method of valuation as it may adopt; provided, however, that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners at such time. The General Partner shall allocate such aggregate value among the assets of the Partnership (in such manner as it determines) to arrive at a fair market value for individual properties.

     (ii) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Capital Accounts of all Partners and the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized in a sale of such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated to the Partners, at such time, pursuant to Section 6.1 in the same manner as any item of gain or loss actually recognized during such period would have been allocated. In determining such Unrealized Gain or Unrealized Loss the aggregate cash amount and fair market value of all Partnership assets (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of an actual distribution that is not made pursuant to Section 12.4 or in the case of a deemed distribution, be determined and allocated in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined and allocated by the Liquidator using such method of valuation as it may adopt.

     Section 5.6 Issuances of Additional Partnership Securities.

     (a) The Partnership may issue additional Partnership Securities and options, rights, warrants and appreciation rights relating to the Partnership Securities for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partners.

     (b) Each additional Partnership Security authorized to be issued by the Partnership pursuant to Section 5.6(a) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of Partnership Securities), as shall be fixed by the General Partner, including (i) the right to share in Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may redeem the Partnership Security; (v) whether such Partnership Security is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi)

the terms and conditions upon which each Partnership Security will be issued, evidenced by certificates and assigned or transferred; (vii) the method for determining the Percentage Interest as to such Partnership Security; and (viii) the right, if any, of each such Partnership Security to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Security.

     (c) The General Partner shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of Partnership Securities and options, rights, warrants and appreciation rights relating to Partnership Securities pursuant to this Section 5.6, (ii) the conversion of the General Partner Interest (represented by General Partner Units) into Units pursuant to the terms of this Agreement, (iii) reflecting admission of such additional Limited Partners in the books and records of the Partnership as the Record Holder of such Limited Partner Interest and (iv) all additional issuances of Partnership Securities. The General Partner shall determine the relative rights, powers and duties of the holders of the Units or other Partnership Securities being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of Partnership Securities or in connection with the conversion of the General Partner Interest into Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Securities are listed or admitted to trading.

     (d) No fractional Units shall be issued by the Partnership.

     Section 5.7 [Reserved.]

     Section 5.8 Limited Preemptive Right. Except as provided in this Section 5.8 and in Section 5.2, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Security, whether unissued, held in the treasury or hereafter created. Prior to the consummation of the GP Acquisition, the General Partner shall have the right, which it may from time to time assign in whole or in part to any of its Affiliates, to purchase Partnership Securities from the Partnership whenever, and on the same terms that, the Partnership issues Partnership Securities to Persons other than the General Partner and its Affiliates, to the extent necessary to maintain the Percentage Interests of the General Partner and its Affiliates equal to that which existed immediately prior to the issuance of such Partnership Securities. The right of the General Partner to purchase Partnership Securities pursuant to this Section 5.8 shall automatically terminate upon the consummation of the GP Acquisition.

     Section 5.9 Splits, Combinations and Other Pro Rata Distributions.

     (a) Subject to Section 5.9(d), the Partnership may make a Pro Rata distribution of Partnership Securities and any options, rights, warrants or appreciation rights relating to any Partnership Security to all Record Holders or may effect a subdivision or combination of Partnership Securities so long as, after any such event (but before giving effect to the exercise of any options, rights, warrants or appreciation rights relating to any Partnership Securities distributed in connection with such event), each Partner shall have the same Percentage Interest

in the Partnership as before such event, and any amounts calculated on a per Unit basis or stated as a number of Units are proportionately adjusted.

     (b) Whenever such a distribution, subdivision or combination of Partnership Securities or any options, rights, warrants or appreciation rights relating to any Partnership Securities is declared, the General Partner shall select a Record Date as of which the distribution, subdivision or combination shall be effective and shall send notice thereof at least 20 days prior to such Record Date to each Record Holder as of a date not less than 10 days prior to the date of such notice. The General Partner also may cause a firm of independent public accountants selected by it to calculate the number of Partnership Securities or any options, rights, warrants or appreciation rights relating to any Partnership Securities to be held by each Record Holder after giving effect to such distribution, subdivision or combination. The General Partner shall be entitled to rely on any certificate provided by such firm as conclusive evidence of the accuracy of such calculation.

     (c) Promptly following any such distribution, subdivision or combination, the Partnership may issue Certificates to the Record Holders of Partnership Securities as of the applicable Record Date representing the new number of Partnership Securities held by such Record Holders, or the General Partner may adopt such other procedures that it determines to be necessary or appropriate to reflect such changes. If any such combination results in a smaller total number of Partnership Securities Outstanding, the Partnership shall require, as a condition to the delivery to a Record Holder of such new Certificate, the surrender of any Certificate held by such Record Holder immediately prior to such Record Date.

     (d) The Partnership shall not issue fractional Units upon any distribution, subdivision or combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units but for the provisions of this Section 5.9(d), each fractional Unit shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to the next higher Unit).

     Section 5.10 Fully Paid and Non-Assessable Nature of Limited Partner Interests. All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Section 17-607 and Section 17-804 of the Delaware Act and any successor or other applicable provisions of the Delaware Act.

ARTICLE VI
ALLOCATIONS AND DISTRIBUTIONS

     Section 6.1 Allocations for Capital Account Purposes. For purposes of maintaining the Capital Accounts and in determining the rights of the Partners among themselves, the Partnership’s items of income, gain, loss and deduction (computed in accordance with Section 5.5(b)) shall be allocated among the Partners in each taxable year (or portion thereof) as provided herein below.

     (a) Net Income Prior to GP Acquisition Date. After giving effect to the special allocations set forth in Section 6.1(e), Net Income for each taxable year (or portion thereof)

ending on or prior to the GP Acquisition Date and all items of income, gain, loss and deduction taken into account in computing Net Income for such taxable year shall be allocated as follows:

     (i) First, 100% to the General Partner, in an amount equal to the aggregate Net Losses allocated to the General Partner pursuant to Section 6.1(b)(iii) for all previous taxable years until the aggregate Net Income allocated to the General Partner pursuant to this Section 6.1(a)(i) for the current taxable year and all previous taxable years is equal to the aggregate Net Losses allocated to the General Partner pursuant to Section 6.1(b)(iii) for all previous taxable years;

     (ii) Second, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests, until the aggregate Net Income allocated to such Partners pursuant to this Section 6.1(a)(ii) for the current taxable year and all previous taxable years is equal to the aggregate Net Losses allocated to such Partners pursuant to Section 6.1(b)(ii) for all previous taxable years; and

     (iii) Third, the balance, if any, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests.

     (b) Net Losses Prior to GP Acquisition Date. After giving effect to the special allocations set forth in Section 6.1(e), Net Losses for each taxable year (or portion thereof) ending on or prior to the GP Acquisition Date and all items of income, gain, loss and deduction taken into account in computing Net Losses for such taxable period shall be allocated as follows:

     (i) First, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests, until the aggregate Net Losses allocated pursuant to this Section 6.1(b)(i) for the current taxable year and all previous taxable years is equal to the aggregate Net Income allocated to such Partners pursuant to Section 6.1(a)(iii) for all previous taxable years, provided that the Net Losses shall not be allocated pursuant to this Section 6.1(b)(i) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable year (or increase any existing deficit balance in its Adjusted Capital Account);

     (ii) Second, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests; provided, that Net Losses shall not be allocated pursuant to this Section 6.1(b)(ii) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable year (or increase any existing deficit balance in its Adjusted Capital Account); and

     (iii) Third, the balance, if any, 100% to the General Partner.

     (c) Net Termination Gains and Losses Prior to the GP Acquisition Date. For periods prior to the GP Acquisition Date, after giving effect to the special allocations set forth in Section 6.1(e), all items of income, gain, loss and deduction taken into account in computing Net Termination Gain or Net Termination Loss for such taxable period shall be allocated in the same manner as such Net Termination Gain or Net Termination Loss is allocated hereunder. All

allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 6.1 and after all distributions of Available Cash provided under Section 6.3 have been made; provided, however, that solely for purposes of this Section 6.1(c), Capital Accounts shall not be adjusted for distributions made pursuant to Section 12.4.

     (i) If a Net Termination Gain is recognized (or deemed recognized pursuant to Section 5.5(d)) prior to the GP Acquisition Date, such Net Termination Gain shall be allocated among the Partners in the following manner (and the Capital Accounts of the Partners shall be increased by the amount so allocated in each of the following subclauses, in the order listed, before an allocation is made pursuant to the next succeeding subclause):

     (A) First, to each Partner having a deficit balance in its Capital Account, in the proportion that such deficit balance bears to the total deficit balances in the Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Capital Account;

     (B) Second, 100% to the General Partner and the Unitholders, in accordance with their respective Percentage Interests;

     (ii) If a Net Termination Loss is recognized (or deemed recognized pursuant to Section 5.5(d)) prior to the GP Acquisition Date, such Net Termination Loss shall be allocated among the Partners in the following manner:

     (A) First, (x) to the General Partner in accordance with its Percentage Interest and (y) to all Unitholders holding Common Units, Pro Rata, a percentage equal to 100% less the percentage applicable to subclause (x) of this clause (A) until the Capital Account in respect of each Common Unit then Outstanding has been reduced to zero; and

     (B) Second, the balance, if any, 100% to the General Partner.

     (d) Allocations After the GP Acquisition Date. After giving effect to the special allocations set forth in Section 6.1(e), Net Income and Net Loss for each taxable year (or portion thereof) after the GP Acquisition Date and all items of income, gain, loss and deduction taken into account in computing Net Income and Net Loss for such taxable year shall be allocated to the Unitholders, in accordance with their respective Percentage Interests.

     (e) Special Allocations. Notwithstanding any other provision of this Section 6.1, the following special allocations shall be made for such taxable period:

     (i) Partnership Minimum Gain Chargeback. Notwithstanding any other provision of this Section 6.1, if there is a net decrease in Partnership Minimum Gain during any Partnership taxable period, each Partner shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the

manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and 1.704-2(j)(2)(i), or any successor provision. For purposes of this Section 6.1(e), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(e) with respect to such taxable period (other than an allocation pursuant to Section 6.1(e)(vi) and Section 6.1(e)(vii)). This Section 6.1(e)(i) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

     (ii) Chargeback of Partner Nonrecourse Debt Minimum Gain. Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(e)(i)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(e), each Partner’s Adjusted Capital Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(e), other than Section 6.1(e)(i) and other than an allocation pursuant to Section 6.1(e)(vi) and Section 6.1(e)(vii), with respect to such taxable period. This Section 6.1(e)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

     (iii) [Reserved.]

     (iv) Qualified Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Section 6.1(e)(i) or Section 6.1(e)(ii).

     (v) Gross Income Allocations. In the event any Partner has a deficit balance in its Capital Account at the end of any Partnership taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 6.1(e)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its Capital

Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(e)(v) were not in this Agreement.

     (vi) Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Partners in accordance with their respective Percentage Interests. If the General Partner determines that the Partnership’s Nonrecourse Deductions should be allocated in a different ratio to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the other Partners, to revise the prescribed ratio to the numerically closest ratio that does satisfy such requirements.

     (vii) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions attributable thereto shall be allocated between or among such Partners in accordance with the ratios in which they share such Economic Risk of Loss.

     (viii) Nonrecourse Liabilities. For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Partners in accordance with their respective Percentage Interests.

     (ix) Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Treasury Regulations.

     (x) Economic Uniformity.

     (A) With respect to any taxable period ending after a right is exercised, all or a portion of the remaining items of Partnership gross income or gain for such taxable period shall be allocated 100% to each Partner who was the initial holder of a Right Exercised Common Unit until each such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such Right Exercised Common Units to an amount equal to the product of (A) the number of Right Exercised Common Units held by such Partner and (B) the Per Unit Capital Amount for a Common Unit (other than a Right Exercised Common Unit).

     (B) With respect to any taxable period of the Partnership ending upon, or after, an event that triggers an adjustment to the Carrying Value of Partnership property pursuant to Section 5.5(d) and during which the Per Unit Capital Amount of an NGP Common Unit is less than the Per Unit Capital Amount of Common Units that are not NGP Common Units, any Unrealized Gains and Unrealized Losses shall be allocated among the Limited Partners so that each Unit, including each NGP Common Unit, has the same Per Unit Capital Amount.

     (C) With respect to any taxable period during which an NGP Common Unit is transferred to any Person who is not an Affiliate of the transferor, all or a portion of the remaining items of Partnership gross income or gain for such taxable period shall be allocated 100% to the transferor Partner of such transferred NGP Common Units until such transferor Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such transferred NGP Common Unit to an amount equal to the Per Unit Capital Amount for a Common Unit.

(xi) Curative Allocation.

     (A) Notwithstanding any other provision of this Section 6.1, other than the Required Allocations, the Required Allocations shall be taken into account in making the Agreed Allocations so that, to the extent possible, the net amount of items of income, gain, loss and deduction allocated to each Partner pursuant to the Required Allocations and the Agreed Allocations, together, shall be equal to the net amount of such items that would have been allocated to each such Partner under the Agreed Allocations had the Required Allocations and the related Curative Allocation not otherwise been provided in this Section 6.1. Notwithstanding the preceding sentence, Required Allocations relating to (1) Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Partnership Minimum Gain and (2) Partner Nonrecourse Deductions shall not be taken into account except to the extent that there has been a decrease in Partner Nonrecourse Debt Minimum Gain. Allocations pursuant to this Section 6.1(e)(xi)(A) shall only be made with respect to Required Allocations to the extent the General Partner determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners. Further, allocations pursuant to this Section 6.1(e)(xi)(A) shall be deferred with respect to allocations pursuant to clauses (1) and (2) hereof to the extent the General Partner determines that such allocations are likely to be offset by subsequent Required Allocations.

     (B) The General Partner shall, with respect to each taxable period, (1) apply the provisions of Section 6.1(e)(xi)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(e)(xi)(A) among the Partners in a manner that is likely to minimize such economic distortions.

Section 6.2 Allocations for Tax Purposes.

     (a) Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 6.1.

     (b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for federal income tax purposes among the Partners as follows:

     (i) (A) In the case of a Contributed Property, such items attributable thereto shall be allocated among the Partners in the manner provided under Section 704(c) of the Code that takes into account the variation between the Agreed Value of such property and its adjusted basis at the time of contribution; and (B) any item of Residual Gain or Residual Loss attributable to a Contributed Property shall be allocated among the Partners in the same manner as its correlative item of “book” gain or loss is allocated pursuant to Section 6.1.

     (ii) (A) In the case of an Adjusted Property, such items shall (1) first, be allocated among the Partners in a manner consistent with the principles of Section 704(c) of the Code to take into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant to Section 5.5(d)(i) or Section 5.5(d)(ii), and (2) second, in the event such property was originally a Contributed Property, be allocated among the Partners in a manner consistent with Section 6.2(b)(i)(A); and (B) any item of Residual Gain or Residual Loss attributable to an Adjusted Property shall be allocated among the Partners in the same manner as its correlative item of “book” gain or loss is allocated pursuant to Section 6.1.

     (iii) The General Partner shall apply the principles of Treasury Regulation Section 1.704-3(d) to eliminate Book-Tax Disparities, except as otherwise determined by the General Partner with respect to goodwill.

     (c) For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions, (ii) make special allocations for federal income tax purposes of income (including gross income), gains, losses, deductions, Unrealized Gains or Unrealized Losses, and (iii) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code (including, if necessary to accomplish the intent of this Agreement, the finalization of Treasury Regulations that may differ from the Proposed Treasury Regulations relied upon in Section 5.5(d)(i) and Section 6.2(i) hereof), or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.2(c) only if such conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Limited Partner Interests issued and Outstanding or the Partnership, and if such allocations are consistent with the principles of Section 704 of the Code.

     (d) The General Partner may determine to depreciate or amortize the portion of an adjustment under Section 743(b) of the Code attributable to unrealized appreciation in any Adjusted Property (to the extent of the unamortized Book-Tax Disparity) using a predetermined rate derived from the depreciation or amortization method and useful life applied to the Partnership’s common basis of such property, despite any inconsistency of such approach with Treasury Regulation Section 1.167(c)-l(a)(6), Treasury Regulation Section 1.197-2(g)(3), the legislative history of Section 743 of the Code or any successor regulations thereto. If the General Partner determines that such reporting position cannot reasonably be taken, the General Partner may adopt depreciation and amortization conventions under which all purchasers acquiring Limited Partner Interests in the same month would receive depreciation and amortization deductions, based upon the same applicable rate as if they had purchased a direct interest in the Partnership’s property. If the General Partner chooses not to utilize such aggregate method, the General Partner may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Limited Partner Interests, so long as such conventions would not have a material adverse effect on the Limited Partners or the Record Holders of any class or classes of Limited Partner Interests.

     (e) In accordance with Treasury Regulation Section 1.1245-1(e), any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 6.2, be characterized as Recapture Income in the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

     (f) All items of income, gain, loss, deduction and credit recognized by the Partnership for federal income tax purposes and allocated to the Partners in accordance with the provisions hereof shall be determined without regard to any election under Section 754 of the Code that may be made by the Partnership; provided, however, that such allocations, once made, shall be adjusted (in the manner determined by the General Partner) to take into account those adjustments permitted or required by Sections 734 and 743 of the Code.

     (g) Each item of Partnership income, gain, loss and deduction, for federal income tax purposes, shall be determined on an annual basis and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the Nasdaq Global Market on the first Business Day of each month; provided, however, that gain or loss on a sale or other disposition of any assets of the Partnership or any other extraordinary item of income or loss realized and recognized other than in the ordinary course of business, as determined by the General Partner, shall be allocated to the Partners as of the opening of the Nasdaq Global Market on the first Business Day of the month in which such gain or loss is recognized for federal income tax purposes. The General Partner may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder.

     (h) Allocations that would otherwise be made to a Limited Partner under the provisions of this Article VI shall instead be made to the beneficial owner of Limited Partner Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method determined by the General Partner.

     (i) If Capital Account balances are reallocated between the Partners in accordance with Section 5.5(d)(i) hereof and Proposed Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(4), beginning with the year of reallocation and continuing until the allocations required are fully taken into account, the Partnership shall make corrective allocations (allocations of items of gross income or gain or loss or deduction for federal income tax purposes that do not have a corresponding book allocation) to take into account the Capital Account reallocation, as provided in Proposed Treasury Regulation Section 1.704-1(b)(4)(x).

     Section 6.3 Distributions.

     (a) Within 45 days following the end of each Quarter, an amount equal to 100% of Available Cash with respect to such Quarter shall, subject to Section 17-607 of the Delaware Act, be distributed in accordance with this Article VI by the Partnership to the Partners as of the Record Date selected by the General Partner in accordance with each Partner’s Percentage Interest.

     (b) Notwithstanding Section 6.3(a), in the event of the dissolution and liquidation of the Partnership, all receipts received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the terms and conditions of, Section 12.4.

     (c) The General Partner may treat taxes paid by the Partnership on behalf of, or amounts withheld with respect to, all or less than all of the Partners, as a distribution of Available Cash to such Partners.

     (d) Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

ARTICLE VII

     Section 7.1 Management.

     (a) The General Partner shall conduct, direct and manage all activities of the Partnership.

     (x) the control of any matters affecting the rights and obligations of the Partnership, including the bringing and defending of actions at law or in equity and

otherwise engaging in the conduct of litigation, arbitration or mediation and the incurring of legal expense and the settlement of claims and litigation;

     (xi) the indemnification of any Person against liabilities and contingencies to the extent permitted by law;

     (xiii) the purchase, sale or other acquisition or disposition of Partnership Securities, or the issuance of options, rights, warrants and appreciation rights relating to Partnership Securities;

     (xiv) the undertaking of any action in connection with the Partnership’s participation in any Group Member; and

     (xv) the entering into of agreements with any of its Affiliates to render services to a Group Member or to itself in the discharge of its duties as General Partner of the Partnership.

     (b) Notwithstanding any other provision of this Agreement, any Group Member Agreement, the Delaware Act or any applicable law, rule or regulation, each of the Partners and the Assignees and each other Person who may acquire an interest in Partnership Securities hereby (i) approves, ratifies and confirms the execution, delivery and performance by the parties thereto of this Agreement and the Group Member Agreement of each other Group Member, the Underwriting Agreement, the Omnibus Agreement, the Contribution Agreement, any Group Member Agreement and the other agreements described in or filed as exhibits to the Registration Statement or Proxy Statement that are related to the transactions contemplated by the Registration Statement or the Proxy Statement; (ii) agrees that the General Partner (on its own or through any officer of the Partnership) is authorized to execute, deliver and perform the agreements referred to in clause (i) of this sentence and the other agreements, acts, transactions and matters described in or contemplated by the Registration Statement or Proxy Statement on behalf of the Partnership without any further act, approval or vote of the Partners or the Assignees or the other Persons who may acquire an interest in Partnership Securities; and (iii) agrees that the execution, delivery or performance by the General Partner, any Group Member or any Affiliate of any of them of this Agreement or any agreement authorized or permitted under this Agreement (including the exercise by the General Partner or any Affiliate of the General Partner of the rights accorded pursuant to Article XV) shall not constitute a breach by the General Partner of any duty that the General Partner may owe the Partnership or the Limited Partners or any other Persons under this Agreement (or any other agreements) or of any duty stated or implied by law or equity.

     Section 7.2 Certificate of Limited Partnership. The General Partner has caused the Certificate of Limited Partnership to be filed with the Secretary of State of the State of Delaware as required by the Delaware Act. The General Partner shall use all reasonable efforts to cause to

be filed such other certificates or documents that the General Partner determines to be necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware or any other state in which the Partnership may elect to do business or own property. To the extent the General Partner determines such action to be necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.4(a), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Limited Partner.

     Section 7.3 Restrictions on the General Partner’s Authority. Except as provided in Article XII and Article XIV, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the assets of the Partnership Group, taken as a whole, in a single transaction or a series of related transactions (including by way of merger, consolidation, other combination or sale of ownership interests of the Partnership’s Subsidiaries) without the approval of holders of a Unit Majority; provided, however, that this provision shall not preclude or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership Group and shall not apply to any forced sale of any or all of the assets of the Partnership Group pursuant to the foreclosure of, or other realization upon, any such encumbrance. Without the approval of holders of a Unit Majority, the General Partner shall not, on behalf of the Partnership, except as permitted under Section 4.6, 11.1 and Section 11.2, elect or cause the Partnership to elect a successor general partner of the Partnership.

     Section 7.4 Reimbursement of the General Partner.

     (a) Except as provided in this Section 7.4 and elsewhere in this Agreement, the General Partner shall not be compensated for its services as a general partner or managing member of any Group Member.

     (b) The General Partner shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine, for (i) all direct and indirect expenses it incurs or payments it makes on behalf of the Partnership Group (including salary, bonus, incentive compensation and other amounts paid to any Person, including Affiliates of the General Partner to perform services for the Partnership Group or for the General Partner in the discharge of its duties to the Partnership Group, which amounts shall also include reimbursement for any Common Units purchased to satisfy obligations of the Partnership under any of its equity compensation plans), and (ii) all other expenses allocable to the Partnership Group or otherwise incurred by the General Partner in connection with operating the Partnership Group’s business (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the Partnership Group. Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7.

     (c) The General Partner and its Affiliates may charge any member of the Partnership Group a management fee to the extent necessary to allow the Partnership Group to reduce the amount of any state franchise or income tax or any tax based upon the revenues or gross margin of any member of the Partnership Group if the tax benefit produced by the payment of such management fee or fees exceeds the amount of such fee or fees.

     (d) The General Partner, without the approval of the Limited Partners (who shall have no right to vote in respect thereof), may propose and adopt on behalf of the Partnership employee benefit plans, employee programs and employee practices (including plans, programs and practices involving the issuance of Partnership Securities or options to purchase or rights, warrants or appreciation rights relating to Partnership Securities), or cause the Partnership to issue Partnership Securities in connection with, or pursuant to, any employee benefit plan, employee program or employee practice maintained or sponsored by the General Partner or any of its Affiliates, in each case for the benefit of employees of the General Partner, any Group Member or any Affiliate or any of them, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The General Partner may cause the Partnership to issue and sell to the General Partner or any of its Affiliates any Partnership Securities that the General Partner or such Affiliates are obligated to provide to any employees pursuant to any such employee benefit plans, employee programs or employee practices. Expenses incurred by the General Partner in connection with any such plans, programs and practices (including the net cost to the General Partner or such Affiliates of Partnership Securities purchased by the General Partner or such Affiliates from the Partnership to fulfill options or awards under such plans, programs and practices) shall be reimbursed in accordance with Section 7.4(b). Any and all obligations of the General Partner under any employee benefit plans, employee programs or employee practices adopted by the General Partner as permitted by this Section 7.4(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or Section 11.2 or the transferee of or successor to all of the General Partner’s General Partner Interest (represented by General Partner Units) pursuant to Section 4.6.

     Section 7.5 Outside Activities.

     (a) The General Partner (i) agrees that its sole business will be to act as a general partner or managing member, as the case may be, of the Partnership and any other partnership or limited liability company of which the Partnership is, directly or indirectly, a partner or member and to undertake activities that are ancillary or related thereto (including being a limited partner in the Partnership) and (ii) shall not engage in any business or activity or incur any debts or liabilities except in connection with or incidental to (A) its performance as general partner or managing member, if any, of one or more Group Members as described in or contemplated by the Registration Statement or (B) the acquiring, owning or disposing of debt or equity securities in any Group Member.

     (b) Each Indemnitee (other than the General Partner) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and

activities of any Group Member, and none of the same shall constitute a breach of this Agreement or any duty expressed or implied by law to any Group Member or any Partner or Assignee. None of any Group Member, any Limited Partner or any other Person shall have any rights by virtue of this Agreement, any Group Member Agreement, or the partnership relationship established hereby in any business ventures of any Indemnitee.

     (c) Notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Indemnitees (other than the General Partner) in accordance with the provisions of this Section 7.5 is hereby approved by the Partnership and all Partners, (ii) it shall be deemed not to be a breach of any fiduciary duty or any other obligation of any type whatsoever of any Indemnitee for the Indemnitees (other than the General Partner) to engage in such business interests and activities in preference to or to the exclusion of the Partnership and (iii) the Indemnitees shall have no obligation hereunder or as a result of any duty expressed or implied by law to present business opportunities to the Partnership. Notwithstanding anything to the contrary in this Agreement, the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to any Indemnitee (including the General Partner). No Indemnitee (including the General Partner) who acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to the Partnership, and such Indemnitee (including the General Partner) shall not be liable to the Partnership, to any Limited Partner or any other Person for breach of any fiduciary or other duty by reason of the fact that such Indemnitee (including the General Partner) pursues or acquires for itself, directs such opportunity to another Person or does not communicate such opportunity or information to the Partnership.

     (d) The General Partner and each of its Affiliates may acquire Units or other Partnership Securities and, except as otherwise provided in this Agreement, shall be entitled to exercise, at their option, all rights relating to all Units or other Partnership Securities acquired by them. The term “Affiliates” when used in this Section 7.5(d) with respect to the General Partner shall not include any Group Member.

     (e) Notwithstanding anything to the contrary in this Agreement, to the extent that any provision of this Section 7.5 purports or is interpreted to have the effect of restricting, eliminating or otherwise modifying the fiduciary duties that might otherwise, as a result of Delaware or other applicable law, be owed by the General Partner to the Partnership and its Limited Partners, or to constitute a waiver or consent by the Limited Partners to any such fiduciary duty, such provisions in this Section 7.5 shall be deemed to have been approved by the Partners.

     Section 7.6 Loans from the General Partner; Loans or Contributions from the Partnership or Group Members.

     (a) The General Partner or any of its Affiliates may lend to any Group Member, and any Group Member may borrow from the General Partner or any of its Affiliates, funds needed or desired by the Group Member for such periods of time and in such amounts as the General Partner may determine; provided, however, that in any such case the lending party may not charge the borrowing party interest at a rate greater than the rate that would be charged the borrowing party or impose terms less favorable to the borrowing party than would be charged or

imposed on the borrowing party by unrelated lenders on comparable loans made on an arm’s-length basis (without reference to the lending party’s financial abilities or guarantees), all as determined by the General Partner. The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by the lending party in connection with the borrowing of such funds. For purposes of this Section 7.6(a) and Section 7.6(b), the term “Group Member” shall include any Affiliate of a Group Member that is controlled by the Group Member.

     (b) The Partnership may lend or contribute to any Group Member, and any Group Member may borrow from the Partnership, funds on terms and conditions determined by the General Partner. Prior to the consummation of the GP Acquisition, no Group Member may lend funds to the General Partner or any of its Affiliates (other than another Group Member).

     Section 7.7 Indemnification.

     (a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Indemnitees shall be indemnified and held harmless by the Partnership from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as an Indemnitee; provided, that the Indemnitee shall not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful; provided, further, no indemnification pursuant to this Section 7.7 shall be available to the General Partner or its Affiliates (other than a Group Member) with respect to its or their obligations incurred pursuant to the Underwriting Agreement, the Omnibus Agreement, the Contribution Agreement or the Transaction Agreement (other than obligations incurred by the General Partner on behalf of the Partnership). Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification.

     (b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to a determination that the Indemnitee is not entitled to be indemnified upon receipt by the Partnership of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Section 7.7.

     (c) The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Outstanding Limited Partner Interests, as a matter of law or otherwise, both as to

actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

     (d) The Partnership may purchase and maintain (or reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner, its Affiliates and such other Persons as the General Partner shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with the Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

     (e) For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 7.7(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Partnership.

     (f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification provisions set forth in this Agreement.

     (g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

     (h) The provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

     (i) No amendment, modification or repeal of this Section 7.7 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Indemnitee to be indemnified by the Partnership, nor the obligations of the Partnership to indemnify any such Indemnitee under and in accordance with the provisions of this Section 7.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

     Section 7.8 Liability of Indemnitees.

     (a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Partnership, the Limited Partners, or any other Persons who have acquired interests in the Partnership Securities, for losses sustained or

liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

     (b) Subject to its obligations and duties as General Partner set forth in Section 7.1(a), the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents, and the General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith.

     (c) To the extent that, at law or in equity, an Indemnitee has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to the Partners, the General Partner and any other Indemnitee acting in connection with the Partnership’s business or affairs shall not be liable to the Partnership or to any Partner for its good faith reliance on the provisions of this Agreement.

     (d) Any amendment, modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

     Section 7.9 Resolution of Conflicts of Interest; Standards of Conduct and Modification of Duties.

     (a) Unless otherwise expressly provided in this Agreement or any Group Member Agreement, whenever a potential conflict of interest exists or arises between the General Partner or any of its Affiliates, on the one hand, and the Partnership, any Group Member or any Partner, on the other, any resolution or course of action by the General Partner or its Affiliates in respect of such conflict of interest shall be permitted and deemed approved by all Partners, and shall not constitute a breach of this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any duty stated or implied by law or equity, if the resolution or course of action in respect of such conflict of interest is (i) approved by Special Approval, (ii) approved by the vote of a majority of the Common Units (excluding Common Units owned by the General Partner and its Affiliates), (iii) on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iv) fair and reasonable to the Partnership, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership). The General Partner shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval of such resolution, and the General Partner may also adopt a resolution or course of action that has not received Special Approval. If Special Approval is not sought and the Board of Directors determines that the resolution or course of action taken with respect to a conflict of interest satisfies either of the standards set forth in clauses (iii) or (iv) above, then it shall be presumed that, in making its

decision, the Board of Directors acted in good faith, and in any proceeding brought by any Limited Partner or by or on behalf of such Limited Partner or any other Limited Partner or the Partnership challenging such approval, the Person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption. Notwithstanding anything to the contrary in this Agreement or any duty otherwise existing at law or equity, the existence of the conflicts of interest described in the Registration Statement or the Proxy Statement are hereby approved by all Partners and shall not constitute a breach of this Agreement.

     (b) Whenever the General Partner makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its capacity as the general partner of the Partnership as opposed to in its individual capacity, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then, unless another express standard is provided for in this Agreement, the General Partner, or such Affiliates causing it to do so, shall make such determination or take or decline to take such other action in good faith and shall not be subject to any other or different standards imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. In order for a determination or other action to be in “good faith” for purposes of this Agreement, the Person or Persons making such determination or taking or declining to take such other action must believe that the determination or other action is in the best interests of the Partnership.

     (c) Whenever the General Partner makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its individual capacity as opposed to in its capacity as the general partner of the Partnership, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then the General Partner, or such Affiliates causing it to do so, are entitled to make such determination or to take or decline to take such other action free of any fiduciary duty or obligation whatsoever to the Partnership, any Limited Partner, and the General Partner, or such Affiliates causing it to do so, shall not be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. By way of illustration and not of limitation, whenever the phrase, “at the option of the General Partner,” or some variation of that phrase, is used in this Agreement, it indicates that the General Partner is acting in its individual capacity. For the avoidance of doubt, whenever the General Partner votes or transfers its Partnership Interests, or refrains from voting or transferring its Partnership Interests, it shall be acting in its individual capacity. The General Partner’s organizational documents may provide that determinations to take or decline to take any action in its individual, rather than representative, capacity may or shall be determined by its members, if the General Partner is a limited liability company, stockholders, if the General Partner is a corporation, or the members or stockholders of the General Partner’s general partner, if the General Partner is a partnership.

     (d) Notwithstanding anything to the contrary in this Agreement, the General Partner and its Affiliates shall have no duty or obligation, express or implied, to (i) sell or otherwise dispose of any asset of the Partnership Group other than in the ordinary course of business or (ii) permit any Group Member to use any facilities or assets of the General Partner and its Affiliates, except as may be provided in contracts entered into from time to time specifically dealing with

such use. Any determination by the General Partner or any of its Affiliates to enter into such contracts shall be at its option.

     (e) Except as expressly set forth in this Agreement, neither the General Partner nor any other Indemnitee shall have any duties or liabilities, including fiduciary duties, to the Partnership or any Limited Partner, and the provisions of this Agreement, to the extent that they restrict, eliminate or otherwise modify the duties and liabilities, including fiduciary duties, of the General Partner or any other Indemnitee otherwise existing at law or in equity, are agreed by the Partners to replace such other duties and liabilities of the General Partner or such other Indemnitee.

     (f) The Unitholders hereby authorize the General Partner, on behalf of the Partnership as a partner or member of a Group Member, to approve of actions by the general partner or managing member of such Group Member similar to those actions permitted to be taken by the General Partner pursuant to this Section 7.9.

     Section 7.10 Other Matters Concerning the General Partner.

     (a) The General Partner may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties.

     (b) The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the opinion (including an Opinion of Counsel) of such Persons as to matters that the General Partner reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion.

     (c) The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers, a duly appointed attorney or attorneys-in-fact or the duly authorized officers of the Partnership.

     Section 7.11 Purchase or Sale of Partnership Securities. The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Securities, including the Subordinated Units and the Incentive Distribution Rights as contemplated by Section 5.1. Such Partnership Securities shall be held by the Partnership as treasury securities unless they are expressly cancelled by action of an appropriate officer of the General Partner or by the Partnership as contemplated by Section 5.1. As long as Partnership Securities are held by any Group Member, such Partnership Securities shall not be considered Outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General Partner may also purchase or otherwise acquire and sell or otherwise dispose of Partnership Securities for its own account, subject to the provisions of Articles IV and X.

     Section 7.12 Registration Rights of the General Partner and its Affiliates.

     (a) If (i) the General Partner or any Affiliate of the General Partner (including for purposes of this Section 7.12, any Person that was an Affiliate of the General Partner as of the date of the First Amended and Restated Agreement or is an Affiliate of the General Partner on the date hereof (notwithstanding that it may later cease to be an Affiliate of the General Partner)) holds Partnership Securities that it desires to sell and (ii) Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such holder of Partnership Securities (the “Holder”) to dispose of the number of Partnership Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and use all commercially reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all Partnership Securities covered by such registration statement have been sold, a registration statement under the Securities Act registering the offering and sale of the number of Partnership Securities specified by the Holder; provided, however, that (i) the Partnership shall not be required to effect more than three registrations pursuant to Section 7.12(a) and Section 7.12(b); (ii) if the Conflicts Committee determines in good faith that the requested registration would be materially detrimental to the Partnership and its Partners because such registration would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving the Partnership, (y) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (z) render the Partnership unable to comply with requirements under applicable securities laws, then the Partnership shall have the right to postpone such requested registration for a period of not more than six months after receipt of the Holder’s request, such right pursuant to this Section 7.12(a) or Section 7.12(b) not to be utilized more than once in any twelve-month period and (iii) neither the General Partner nor any of its Affiliates shall be entitled to any registration rights pursuant to this Section 7.12 until the earlier to occur of the termination of the Existing Registration Rights Agreement or such time as there ceases to be any Registrable Securities (as defined in the Existing Registration Rights Agreement). Except as provided in the preceding sentence, the Partnership shall be deemed not to have used all commercially reasonable efforts to keep the registration statement effective during the applicable period if it voluntarily takes any action that would result in Holders of Partnership Securities covered thereby not being able to offer and sell such Partnership Securities at any time during such period, unless such action is required by applicable law. In connection with any registration pursuant to the first sentence of this Section 7.12(a), the Partnership shall (i) promptly prepare and file (A) such documents as may be necessary to register or qualify the securities subject to such registration under the securities laws of such states as the Holder shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such registration, and (B) such documents as may be necessary to apply for listing or to list the Partnership Securities subject to such registration on such National Securities Exchange as the Holder shall reasonably request, and (ii) do any and all other acts and things that may be necessary or appropriate to enable the Holder to consummate a public sale of such Partnership Securities in such states. Except as set forth in Section 7.12(d), all costs and expenses of any

such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

     (b) If any Holder holds Partnership Securities that it desires to sell and Rule 144 of the Securities Act (or any successor rule or regulation to Rule 144) or another exemption from registration is not available to enable such Holder to dispose of the number of Partnership Securities it desires to sell at the time it desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and use all reasonable efforts to cause to become effective and remain effective for a period of not less than two years following its effective date or such shorter period as shall terminate when all Partnership Securities covered by such shelf registration statement have been sold, a “shelf” registration statement covering the Partnership Securities specified by the Holder on an appropriate form under Rule 415 under the Securities Act, or any similar rule that may be adopted by the Commission; provided, however, that the Partnership shall not be required to effect more than three registrations pursuant to Section 7.12(a) and this Section 7.12(b); and provided further, however, that if the Conflicts Committee determines in good faith that any offering under, or the use of any prospectus forming a part of, the shelf registration statement would be materially detrimental to the Partnership and its Partners because such offering or use would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving the Partnership, (y) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (z) render the Partnership unable to comply with requirements under applicable securities laws, then the Partnership shall have the right to suspend such offering or use for a period of not more than six months after receipt of the Holder’s request, such right pursuant to Section 7.12(a) or this Section 7.12(b) not to be utilized more than once in any twelve-month period. Except as provided in the preceding sentence, the Partnership shall be deemed not to have used all reasonable efforts to keep the shelf registration statement effective during the applicable period if it voluntarily takes any action that would result in Holders of Partnership Securities covered thereby not being able to offer and sell such Partnership Securities at any time during such period, unless such action is required by applicable law. In connection with any shelf registration pursuant to this Section 7.12(b), the Partnership shall (i) promptly prepare and file (A) such documents as may be necessary to register or qualify the securities subject to such shelf registration under the securities laws of such states as the Holder shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such shelf registration, and (B) such documents as may be necessary to apply for listing or to list the Partnership Securities subject to such shelf registration on such National Securities Exchange as the Holder shall reasonably request, and (ii) do any and all other acts and things that may be necessary or appropriate to enable the Holder to consummate a public sale of such Partnership Securities in such states. Except as set forth in Section 7.12(d), all costs and expenses of any such shelf registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

     (c) If the Partnership shall at any time propose to file a registration statement under the Securities Act for an offering of equity securities of the Partnership for cash (other than an offering relating solely to an employee benefit plan), the Partnership shall use all reasonable efforts to include such number or amount of securities held by the Holder in such registration statement as the Holder shall request; provided, that the Partnership is not required to make any effort or take any action to so include the securities of the Holder once the registration statement is declared effective by the Commission or otherwise becomes effective, including any registration statement providing for the offering from time to time of securities pursuant to Rule 415 of the Securities Act. If the proposed offering pursuant to this Section 7.12(c) shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such offering advise the Partnership and the Holder in writing that in their opinion the inclusion of all or some of the Holder’s Partnership Securities would adversely and materially affect the success of the offering, the Partnership shall include in such offering only that number or amount, if any, of securities held by the Holder that, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. Except as set forth in Section 7.12(d), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder.

     (d) If underwriters are engaged in connection with any registration referred to in this Section 7.12, the Partnership shall provide indemnification, representations, covenants, opinions and other assurance to the underwriters in form and substance reasonably satisfactory to such underwriters. Further, in addition to and not in limitation of the Partnership’s obligation under Section 7.7, the Partnership shall, to the fullest extent permitted by law, indemnify and hold harmless the Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “Indemnified Persons”) from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (hereinafter referred to in this Section 7.12(d) as a “claim” and in the plural as “claims”) based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which any Partnership Securities were registered under the Securities Act or any state securities or Blue Sky laws, in any preliminary prospectus (if used prior to the effective date of such registration statement), or in any summary or final prospectus or in any amendment or supplement thereto (if used during the period the Partnership is required to keep the registration statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein not misleading; provided, however, that the Partnership shall not be liable to any Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, such preliminary, summary or final prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Indemnified Person specifically for use in the preparation thereof.

     (c) Any transfer of a Limited Partner Interest shall not entitle the transferee to share in the profits and losses, to receive distributions, to receive allocations of income, gain, loss, deduction or credit or any similar item or to any other rights to which the transferor was entitled until the transferee becomes a Limited Partner pursuant to Section 10.1(a).

The Partners hereby agree that only the Events of Withdrawal described in this Section 11.1 shall result in the withdrawal of the General Partner from the Partnership.

     (b) Withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal that is not in violation of Section 11.1(c) shall not constitute a breach of this Agreement under the following circumstances: (i) prior to 12:00 midnight, Central Standard Time, on September 30, 2016, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice of its intention to withdraw to the Limited Partners; provided, that prior to the effective date of such withdrawal, the withdrawal is approved by Unitholders holding at least a majority of the Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) and the General Partner delivers to the Partnership an Opinion of Counsel (“Withdrawal Opinion of Counsel”) that such withdrawal (following the selection of the successor General Partner) would not result in the loss of the limited liability of any Limited Partner or any Group Member or cause any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed); (ii) at any time after 12:00 midnight, Central Standard Time, on September 30, 2016, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice to the Unitholders, such withdrawal to take effect on the date specified in such notice; (iii) at any time that the General Partner ceases to be the General Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2; or (iv) notwithstanding clause (i) of this sentence, at any time that the General Partner voluntarily withdraws by giving at least 90 days’ advance notice of its intention to withdraw to the Limited Partners, such withdrawal to take effect on the date specified in the notice, if at the time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of record or control at least 50% of the Outstanding Units. The withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal that is not in violation of Section 11.1(c) shall also constitute the withdrawal of the General Partner as general partner or managing member, if any, to the extent applicable, of the other Group Members. If the General Partner gives a notice of withdrawal pursuant to Section 11.1(a)(i), the holders of a Unit Majority, may, prior to the effective date of such withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If, prior to the effective date of the General Partner’s withdrawal, a successor is not selected by the Unitholders as provided herein or the Partnership does not receive a Withdrawal Opinion of Counsel, the Partnership shall be dissolved in accordance with Section 12.1. Any successor General Partner elected in accordance with the terms of this Section 11.1 shall be subject to the provisions of Section 10.2.

     (c) After the consummation of the GP Acquisition, the General Partner may not withdraw as general partner of the Partnership at any time for any reason whatsoever. Any

attempt of withdrawal by the General Partner shall, to the fullest extent permitted by law, be null and void. The General Partner may only be removed pursuant to Section 11.2.

     (d) Notwithstanding Section 11.1(c), if the General Partner withdraws as general partner of the Partnership after the consummation of the GP Acquisition in violation of this Agreement pursuant to Section 17-602 of the Delaware Act:

     (i) The withdrawing General Partner shall give 90 days prior notice of such withdrawal to the Limited Partners.

     (iii) A successor General Partner elected pursuant to Section 11.1(d)(ii) shall be admitted to the Partnership as the General Partner, effective as of the date immediately prior to the withdrawal of the predecessor General Partner; provided, however, that no such successor shall be admitted to the Partnership until such successor has executed and delivered this Agreement and such other documents or instruments as may be required to effect such admission. Any such successor is hereby authorized to and shall, subject to the terms hereof, carry on the business of the Partnership without dissolution.

     (iv) The Person so elected as successor General Partner shall automatically become the successor general partner or managing member, as the case may be, of the other Group Members of which the General Partner is a general partner or a managing member.

     (v) Upon the withdrawal of the General Partner, if a successor General Partner is elected pursuant to Section 11.1(d)(ii), the Partnership shall not be dissolved and such successor General Partner shall continue the business of the Partnership.

     Section 11.2 Removal of the General Partner. The General Partner may be removed (a) if such removal is prior to the GP Acquisition Date and is approved by the Unitholders holding at least 66 2/3% of the Outstanding Units (including Units held by the General Partner and its Affiliates) voting as a single class or (b) if such removal is on or after the GP Acquisition Date and is approved by the Unitholders holding 100% of the Outstanding Units (including Units held by the General Partner and its Affiliates) voting as a single class. Any such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a majority of the Outstanding Common Units voting as a single class (including Units held by the General Partner and its Affiliates). Such removal shall be effective immediately following the admission of a successor General Partner pursuant to Section 10.2. The removal of the General Partner shall also automatically constitute the removal of the General Partner as general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If a Person is elected as a successor General Partner in accordance with the terms of this Section 11.2, such Person shall, upon admission pursuant to Section 10.2, automatically become a successor general partner or managing member, to the extent applicable, of the other

Group Members of which the General Partner is a general partner or a managing member. The right of the holders of Outstanding Units to remove the General Partner shall not exist or be exercised unless the Partnership has received an opinion opining as to the matters covered by a Withdrawal Opinion of Counsel. Any successor General Partner elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.2.

     Section 11.3 Interest of Departing General Partner and Successor General Partner.

     (a) In the event of (i) withdrawal of the General Partner under circumstances where such withdrawal does not violate this Agreement or (ii) removal of the General Partner by the holders of Outstanding Units under circumstances where Cause does not exist, if the successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2, the Departing General Partner shall have the option, exercisable prior to the effective date of the departure of such Departing General Partner, to require its successor to purchase its General Partner Interest (represented by General Partner Units) and its general partner interest (or equivalent interest), if any, in the other Group Members (collectively, the “Combined Interest”) in exchange for an amount in cash equal to the fair market value of such Combined Interest, such amount to be determined and payable as of the effective date of its departure. If the General Partner is removed by the Unitholders under circumstances where Cause exists or if the General Partner withdraws under circumstances where such withdrawal violates this Agreement, and if a successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2 (or if the business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner), such successor shall have the option, exercisable prior to the effective date of the departure of such Departing General Partner (or, in the event the business of the Partnership is continued, prior to the date the business of the Partnership is continued), to purchase the Combined Interest for such fair market value of such Combined Interest of the Departing General Partner. In either event, the Departing General Partner shall be entitled to receive all reimbursements due such Departing General Partner pursuant to Section 7.4, including any employee-related liabilities (including severance liabilities), incurred in connection with the termination of any employees employed by the Departing General Partner or its Affiliates (other than any Group Member) for the benefit of the Partnership or the other Group Members.

     For purposes of this Section 11.3(a), the fair market value of the Departing General Partner’s Combined Interest shall be determined by agreement between the Departing General Partner and its successor or, failing agreement within 30 days after the effective date of such Departing General Partner’s departure, by an independent investment banking firm or other independent expert selected by the Departing General Partner and its successor, which, in turn, may rely on other experts, and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other independent expert within 45 days after the effective date of such departure, then the Departing General Partner shall designate an independent investment banking firm or other independent expert, the Departing General Partner’s successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which third independent investment banking firm or other independent expert shall determine the fair market value of the Combined Interest

of the Departing General Partner. In making its determination, such third independent investment banking firm or other independent expert may consider the then current trading price of Units on any National Securities Exchange on which Units are then listed or admitted to trading, the value of the Partnership’s assets, the rights and obligations of the Departing General Partner and other factors it may deem relevant.

     (b) If the Combined Interest is not purchased in the manner set forth in Section 11.3(a), the Departing General Partner (or its transferee) shall become a Limited Partner and its Combined Interest shall be converted into Common Units pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 11.3(a), without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor General Partner shall indemnify the Departing General Partner (or its transferee) as to all debts and liabilities of the Partnership arising on or after the date on which the Departing General Partner (or its transferee) becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest of the Departing General Partner to Common Units will be characterized as if the Departing General Partner (or its transferee) contributed its Combined Interest to the Partnership in exchange for the newly issued Common Units.

     (c) If a successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2 (or if the business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner) and the option described in Section 11.3(a) is not exercised by the party entitled to do so, the successor General Partner shall, at the effective date of its admission to the Partnership, contribute to the Partnership cash in the amount equal to the product of the Percentage Interest of the Departing General Partner and the Net Agreed Value of the Partnership’s assets on such date. In such event, such successor General Partner shall, subject to the following sentence, be entitled to its Percentage Interest of all Partnership allocations and distributions to which the Departing General Partner was entitled. In addition, the successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General Partner’s admission, the successor General Partner’s interest in all Partnership distributions and allocations shall be its Percentage Interest.

     Section 11.4 [Reserved.]

     Section 11.5 Withdrawal of Limited Partners. No Limited Partner shall have any right to withdraw from the Partnership; provided, however, that when a transferee of a Limited Partner’s Limited Partner Interest becomes a Record Holder of the Limited Partner Interest so transferred, such transferring Limited Partner shall cease to be a Limited Partner with respect to the Limited Partner Interest so transferred.

Upon (a) dissolution of the Partnership following an Event of Withdrawal caused by the withdrawal or removal of the General Partner as provided in Section 11.1(a)(i) or (iii) and the failure of the Partners to select a successor to such Departing General Partner pursuant to Section 11.1 or Section 11.2, then within 90 days thereafter, (b) dissolution of the Partnership upon (i) an event constituting an Event of Withdrawal as defined in Section 11.1(a)(iv), (v) or (vi), or (ii) the withdrawal or removal of the General Partner as provided in Section 11.1(d) or Section 11.2 and the failure of the Partners to select a successor to such Departing General Partner pursuant to Section 11.1 or Section 11.2, then, to the maximum extent permitted by law, within 180 days thereafter, the holders of a Unit Majority may elect to continue the business of the Partnership on the same terms and conditions set forth in this Agreement by appointing as a successor General Partner a Person approved by the holders of a Unit Majority. Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then:

     (i) the Partnership shall continue without dissolution unless earlier dissolved in accordance with this Article XII;

     (ii) if the successor General Partner is not the former General Partner, then the interest of the former General Partner shall be treated in the manner provided in Section 11.3; and

     (iii) the successor General Partner shall be admitted to the Partnership as General Partner, effective as of the Event of Withdrawal, by agreeing in writing to be

bound by this Agreement; provided, that the right of the holders of a Unit Majority to approve a successor General Partner and to continue the business of the Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability of any Limited Partner and (y) neither the Partnership nor any Group Member would be treated as an association taxable as a corporation or otherwise be taxable as an entity for federal income tax purposes upon the exercise of such right to continue (to the extent not already so treated or taxed).

     Section 12.3 Liquidator. Upon dissolution of the Partnership, unless the business of the Partnership is continued pursuant to Section 12.2, the General Partner shall select one or more Persons to act as Liquidator. The Liquidator (if other than the General Partner) shall be entitled to receive such compensation for its services as may be approved by holders of at least a Unit Majority. The Liquidator (if other than the General Partner) shall agree not to resign at any time without 15 days’ prior notice and may be removed at any time, with or without cause, by notice of removal approved by holders of at least a Unit Majority. Upon dissolution, removal or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of at least a Unit Majority. The right to approve a successor or substitute Liquidator in the manner provided herein shall be deemed to refer also to any such successor or substitute Liquidator approved in the manner herein provided. Except as expressly provided in this Article XII, the Liquidator approved in the manner provided herein shall have and may exercise, without further authorization or consent of any of the parties hereto, all of the powers conferred upon the General Partner under the terms of this Agreement (but subject to all of the applicable limitations, contractual and otherwise, upon the exercise of such powers, other than the limitation on sale set forth in Section 7.3) necessary or appropriate to carry out the duties and functions of the Liquidator hereunder for and during the period of time required to complete the winding up and liquidation of the Partnership as provided for herein.

     Section 12.4 Liquidation. The Liquidator shall proceed to dispose of the assets of the Partnership, discharge its liabilities, and otherwise wind up its affairs in such manner and over such period as determined by the Liquidator, subject to Section 17-804 of the Delaware Act and the following:

     (a) The assets may be disposed of by public or private sale or by distribution in kind to one or more Partners on such terms as the Liquidator and such Partner or Partners may agree. If any property is distributed in kind, the Partner receiving the property shall be deemed for purposes of Section 12.4(c) to have received cash equal to its fair market value; and contemporaneously therewith, appropriate cash distributions must be made to the other Partners. The Liquidator may defer liquidation or distribution of the Partnership’s assets for a reasonable time if it determines that an immediate sale or distribution of all or some of the Partnership’s assets would be impractical or would cause undue loss to the Partners. The Liquidator may distribute the Partnership’s assets, in whole or in part, in kind if it determines that a sale would be impractical or would cause undue loss to the Partners.

     (b) Liabilities of the Partnership include amounts owed to the Liquidator as compensation for serving in such capacity (subject to the terms of Section 12.3) and amounts to

Partners otherwise than in respect of their distribution rights under Article VI. With respect to any liability that is contingent, conditional or unmatured or is otherwise not yet due and payable, the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be distributed as additional liquidation proceeds.

     (c) All property and all cash in excess of that required to discharge liabilities as provided in Section 12.4(b) shall be distributed to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to this Section 12.4(c)) for the taxable year of the Partnership during which the liquidation of the Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable year (or, if later, within 90 days after said date of such occurrence).

     Section 12.5 Cancellation of Certificate of Limited Partnership. Upon the completion of the distribution of Partnership cash and property as provided in Section 12.4 in connection with the liquidation of the Partnership, the Certificate of Limited Partnership and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken.

     Section 12.6 Return of Contributions. The General Partner shall not be personally liable for, and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate, the return of the Capital Contributions of the Limited Partners or Unitholders, or any portion thereof, it being expressly understood that any such return shall be made solely from Partnership assets.

     Section 12.7 Waiver of Partition. To the maximum extent permitted by law, each Partner hereby waives any right to partition of the Partnership property.

     Section 12.8 Capital Account Restoration. No Limited Partner shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Partnership. If such liquidation occurs prior to the consummation of the GP Acquisition, the General Partner shall be obligated to restore any negative balance in its Capital Account upon liquidation of its interest in the Partnership by the end of the taxable year of the Partnership during which such liquidation occurs, or, if later, within 90 days after the date of such liquidation.

ARTICLE XIII
AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS; RECORD DATE

     Section 13.1 Amendments to be Adopted Solely by the General Partner. Each Partner agrees that the General Partner, without the approval of any Partner, may amend any provision of this Agreement and execute, swear to, acknowledge, deliver, file and record whatever documents may be required in connection therewith, to reflect:

     (a) a change in the name of the Partnership, the location of the principal place of business of the Partnership, the registered agent of the Partnership or the registered office of the Partnership;

     (b) admission, substitution, withdrawal or removal of Partners in accordance with this Agreement;

     (c) a change that the General Partner determines to be necessary or appropriate to qualify or continue the qualification of the Partnership as a limited partnership or a partnership in which the Limited Partners have limited liability under the laws of any state or to ensure that the Group Members will not be treated as associations taxable as corporations or otherwise taxed as entities for federal income tax purposes;

     (d) a change that the General Partner determines, (i) does not adversely affect the Limited Partners (including any particular class of Partnership Interests as compared to other classes of Partnership Interests) in any material respect, (ii) to be necessary or appropriate to (A) satisfy any requirements, conditions or guidelines contained in any opinion, directive, order, ruling or regulation of any federal or state agency or judicial authority or contained in any federal or state statute (including the Delaware Act) or (B) facilitate the trading of the Units (including the division of any class or classes of Outstanding Units into different classes to facilitate uniformity of tax consequences within such classes of Units) or comply with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are or will be listed or admitted to trading, (iii) to be necessary or appropriate in connection with action taken by the General Partner pursuant to Section 5.9 or (iv) is required to effect the intent expressed in the Registration Statement or Proxy Statement or the intent of the provisions of this Agreement or is otherwise contemplated by this Agreement;

     (e) a change in the fiscal year or taxable year of the Partnership and any other changes that the General Partner determines to be necessary or appropriate as a result of a change in the fiscal year or taxable year of the Partnership including, if the General Partner shall so determine, a change in the definition of “Quarter” and the dates on which distributions are to be made by the Partnership;

     (f) an amendment that is necessary, in the Opinion of Counsel, to prevent the Partnership, or the General Partner or its directors, officers, trustees or agents from in any manner being subjected to the provisions of the Investment Company Act of 1940, as amended, the Investment Advisers Act of 1940, as amended, or “plan asset” regulations adopted under the Employee Retirement Income Security Act of 1974, as amended, regardless of whether such are substantially similar to plan asset regulations currently applied or proposed by the United States Department of Labor;

     (g) an amendment that the General Partner determines to be necessary or appropriate in connection with the authorization of issuance of any class or series of Partnership Securities pursuant to Section 5.6;

     (h) any amendment expressly permitted in this Agreement to be made by the General Partner acting alone;

     (i) an amendment effected, necessitated or contemplated by a Merger Agreement approved in accordance with Section 14.3;

     (j) an amendment that the General Partner determines to be necessary or appropriate to reflect and account for the formation by the Partnership of, or investment by the Partnership in, any corporation, partnership, joint venture, limited liability company or other entity, in connection with the conduct by the Partnership of activities permitted by the terms of Section 2.4;

     (k) a merger, conveyance or conversion pursuant to Section 14.3(d); or

     (l) any other amendments substantially similar to the foregoing.

     Section 13.2 Amendment Procedures. Except as provided in Section 13.1 and Section 13.3, all amendments to this Agreement shall be made in accordance with the following requirements. Amendments to this Agreement may be proposed only by the General Partner; provided, however, that the General Partner shall have no duty or obligation to propose any amendment to this Agreement and may decline to do so free of any fiduciary duty or obligation whatsoever to the Partnership or any Limited Partner and, in declining to propose an amendment, to the fullest extent permitted by law shall not be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. A proposed amendment shall be effective upon its approval by the General Partner and the holders of a Unit Majority, unless a greater or different percentage is required under this Agreement or by Delaware law. Each proposed amendment that requires the approval of the holders of a specified percentage of Outstanding Units shall be set forth in a writing that contains the text of the proposed amendment. If such an amendment is proposed, the General Partner shall seek the written approval of the requisite percentage of Outstanding Units or call a meeting of the Unitholders to consider and vote on such proposed amendment. The General Partner shall notify all Record Holders upon final adoption of any such proposed amendments.

     Section 13.3 Amendment Requirements.

     (a) Notwithstanding the provisions of Section 13.1 and Section 13.2, no provision of this Agreement that establishes a percentage of Outstanding Units (including Units deemed owned by the General Partner) required to take any action shall be amended, altered, changed, repealed or rescinded in any respect that would have the effect of reducing such voting percentage unless such amendment is approved by the written consent or the affirmative vote of holders of Outstanding Units whose aggregate Outstanding Units constitute not less than the voting requirement sought to be reduced.

     (b) Notwithstanding the provisions of Section 13.1 and Section 13.2, no amendment to this Agreement may (i) enlarge the obligations of any Limited Partner without its consent, unless such shall be deemed to have occurred as a result of an amendment approved pursuant to Section 13.3(c), or (ii) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, the General

Partner or any of its Affiliates without its consent, which consent may be given or withheld at its option.

     (c) Except as provided in Section 14.3, and without limitation of the General Partner’s authority to adopt amendments to this Agreement without the approval of any Partners or Assignees as contemplated in Section 13.1, any amendment that would have a material adverse effect on the rights or preferences of any class of Partnership Interests in relation to other classes of Partnership Interests must be approved by the holders of not less than a majority of the Outstanding Partnership Interests of the class affected.

     (d) Notwithstanding any other provision of this Agreement, except for amendments pursuant to Section 13.1 and except as otherwise provided by Section 14.3(b), no amendments shall become effective without the approval of the holders of at least 90% of the Outstanding Units voting as a single class unless the Partnership obtains an Opinion of Counsel to the effect that such amendment will not affect the limited liability of any Limited Partner under applicable partnership law of the state under whose laws the Partnership is organized.

     (e) Except as provided in Section 13.1, this Section 13.3 shall only be amended with the approval of the holders of at least 90% of the Outstanding Units.

     Section 13.4 Common Unitholder Meetings. (a) All acts of Limited Partners to be taken pursuant to this Agreement shall be taken in the manner provided in this Article XIII.

     (b) Special meetings of the Limited Partners may be called by the General Partner or by Limited Partners owning 20% or more of the Outstanding Units of the class or classes for which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and indicating the general or specific purposes for which the special meeting is to be called. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or indirectly through the Transfer Agent. A meeting shall be held at a time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the mailing of notice of the meeting. Limited Partners shall not vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business.

     (c) (i) During each calendar year beginning on or after the GP Acquisition Date, an annual meeting of the Limited Partners for the election of the Elected Directors and such other matters as the Board of Directors shall submit to a vote of the Limited Partners shall be held at such date and time as may be fixed from time to time by the General Partner at such place within or without the State of Delaware as may be fixed from time to time by the General Partner and all as stated in the notice of the meeting. Notice of the annual meeting shall be given in accordance with Section 13.5 not less than 10 days nor more than 60 days prior to the date of

such meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern).

     (ii) The Limited Partners entitled to vote at the annual meeting shall vote together as a single class. The Limited Partners entitled to vote shall elect by a plurality of the votes cast at such meeting a number of individuals to serve as Elected Directors as is determined in accordance with Section 13.13(b) solely from the individuals nominated in accordance with the provisions of this Section 13.4(c). The exercise by a Limited Partner of the right to elect the Elected Directors and any other rights afforded to such Limited Partner under this Section 13.4(c) shall be in such Limited Partner’s capacity as a limited partner of the Partnership and shall not cause a Limited Partner to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize such Limited Partner’s limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business.

     (iii) Each Limited Partner entitled to vote shall be entitled to one vote for each Outstanding Unit that is registered in the name of such Limited Partner on the Record Date for such meeting; provided, however, that prior to the Final NGP Voting Termination Event, no NGP Party shall be entitled to vote Units otherwise entitled to vote at the annual meeting in connection with any election of Elected Directors pursuant to this Section 13.4(c), and any such Units that are not entitled to be voted pursuant to this provision shall not be deemed to be Outstanding for purposes of determining a quorum under Section 13.9.

     (iv) Nominations of Persons for election as Elected Directors to the Board of Directors may be made at an annual meeting only (A) by or at the direction of a majority of the Elected Directors on the Board of Directors, or (B) by any Limited Partner (other than any NGP Party prior to the Final NGP Voting Termination Event) who was a Record Holder of at least 20% of Outstanding Units at the time of giving notice provided for in this Agreement, who is entitled to vote at the meeting and who complies with the notice procedures set forth below; provided, however, that such nominations shall be subject to the requirement that the Board of Directors have and maintain at least three Elected Directors meeting the independence and experience requirements as set forth most recently by any National Securities Exchange on which any Units or other Partnership Securities are listed or quoted. For nominations by a Limited Partner pursuant to clause (B) above, the Limited Partner must have given timely notice thereof in writing to the General Partner. To be timely, a Limited Partner’s notice shall be delivered to the General Partner at the principal executive offices of the General Partner not later than the close of business on the 120th calendar day, nor earlier than the close of business on the 135th calendar day, prior to the first anniversary of the preceding year’s annual meeting (which, for the first calendar year beginning on or after the GP Acquisition Date, shall be deemed to be May 1 of the immediately preceding year), provided, however, that if the annual meeting is called for a date that is more than 30

days earlier or more than 60 days after such anniversary date, to be timely, the Limited Partner’s notice must be so received not earlier than the close of business on the 135th day before the meeting and not later than the later to occur of (x) the close of business on the 120th day before the meeting and (y) the close of business on the 10th day following the day on which public announcement of the date of the annual meeting is first made by the Partnership. The adjournment of an annual meeting shall not commence a new time period for the giving of a Limited Partner’s notice as described above. Such Limited Partner’s notice shall set forth (Y) as to each person whom the Limited Partner proposes to nominate for election or reelection as an Elected Director all information relating to such person that is required to be disclosed in solicitations of proxies for the election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a Director if elected); and (Z) as to the Limited Partner giving the notice (1) the name and address of such Limited Partner, and the name and address of (x) any Person controlling, directly or indirectly, or acting in concert with, such Limited Partner, (y) any beneficial owner of Units owned of record or beneficially by such Limited Partner, and (z) any Person controlling, controlled by or under common control with such Person referred to in the preceding clauses (x) and (y) (such person described in (x), (y) and (z), a “Limited Partner Associated Person”), (2) the class or series and number of Units that are owned of record or directly or indirectly owned beneficially by such Limited Partner and any Limited Partner Associated Person, (3) any option, warrant, convertible security, unit appreciation right, swap or similar right with an exercise or conversion privilege or a settlement payment or mechanism at a price related to any class or series of Units or with a value derived in whole or in part from the value of any class or series of Units, whether or not such instrument or right is subject to settlement in the underlying class or series of Units or otherwise (a “Derivative Instrument”) directly or indirectly owned beneficially by such Limited Partner or Limited Partner Associated Person and any other direct or indirect opportunity of such Limited Partner or any Limited Partner Associated Person to profit or share in any profit derived from any increase or decrease in the value of the Units, (4) any proxy (other than a revocable proxy given in response to a solicitation made pursuant to Section 14(a) of the Securities Exchange Act by way of a solicitation statement filed on Schedule 14A), contract, arrangement, understanding or relationship pursuant to which such Limited Partner or any Limited Partner Associated Person has a right to vote any Units, (5) any short interest in any Units held by such Limited Partner or any Limited Partner Associated Person (for purposes of this subclause a Person shall be deemed to have a short interest in a Unit if such Person directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has the opportunity to profit or share in any profit derived from any decrease in the value of the subject Unit), (6) any rights beneficially owned, directly or indirectly, by such Limited Partner or Limited Partner Associated Person to distributions of the Partnership that are separated or separable from the underlying Units, (7) any proportionate interest in the Units or Derivative Instruments held, directly or indirectly, by a general or limited partnership in which such Limited Partner or any Limited Partner Associated Person is a general partner or, directly or indirectly, beneficially owns an interest in a general partner, (8) any performance-related fees (other than an asset-based fee) that such Limited Partner or any

Limited Partner Associated Person is entitled to based on any increase or decrease in the value of the Units or Derivative Instruments, if any, including without limitation any such interests held by members of such Limited Partner’s or any Limited Partner Associated Person’s immediate family sharing the same household, (9) a description of all agreements, arrangements or understandings (written or oral) between or among such Limited Partner, any Limited Partner Associated Person, any proposed nominee or any other Person or Persons (including their names) pursuant to which the nomination or nominations are to be made by such Limited Partner, (10) a representation that such Limited Partner intends to appear in person or by proxy at the meeting to nominate the persons named in its notice, (11) any other information relating to such Limited Partner and any Limited Partner Associated Person that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors pursuant to Regulation 14A under the Securities Exchange Act, (12) a description of all direct and indirect compensation and other material monetary agreements, arrangements and understandings during the past three years, and any other material relationships, between or among such Limited Partner or any Limited Partner Associated Person, or others acting in concert therewith, on the one hand, and each proposed nominee, and his or her respective affiliates and associates, or others acting in concert therewith, on the other hand, and (13) a statement of whether such Limited Partner or any Limited Partner Associated Person intends, or is part of a group that intends, to solicit proxies for the election of the proposed nominee. Other than as provided in Section 13.13, only such persons who are nominated in accordance with the procedures set forth in this provision shall be eligible to serve as Elected Directors. The chairman of the meeting shall have the power and duty to determine whether a nomination was made in accordance with the procedures set forth above and to declare that such defective nomination shall be disregarded.

     (v) The General Partner shall use its reasonable efforts to take such action as shall be necessary or appropriate to give effect to and implement the provisions of this Section 13.4(c), including, without limitation, amending the limited partnership agreement of the General Partner and the limited liability company agreement of the general partner of the General Partner. The General Partner or, if the General Partner is a limited partnership, its general partner, shall be governed by organizational documents that permit the effectuation of the relevant provisions of this Agreement, including, without limitation, the provisions of this Article XIII and the provisions relating to the Conflicts Committee.

     (vi) This Section 13.4(c) may not be amended except as permitted pursuant to Section 13.1(d) or upon the prior approval of Limited Partners that hold two-thirds of the Outstanding Units; provided that, prior to the Final NGP Voting Termination Event, any Units beneficially owned by any NGP Party shall not be voted and shall not be considered Outstanding for the purposes of such approval.

     (vii) The provisions of this Section 13.4(c) shall have no effect prior to the consummation of the GP Acquisition.

     Section 13.5 Notice of a Meeting. Notice of a meeting called pursuant to Section 13.4 shall be given to the Record Holders of the class or classes of Units for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1. The notice shall be deemed to have been given at the time when deposited in the mail or sent by other means of written communication.

     Section 13.6 Record Date. For purposes of determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.11 the General Partner may set a Record Date, which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern) or (b) in the event that approvals are sought without a meeting, the date by which Limited Partners are requested in writing by the General Partner to give such approvals. If the General Partner does not set a Record Date, then (a) the Record Date for determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners shall be the close of business on the day next preceding the day on which notice is given, and (b) the Record Date for determining the Limited Partners entitled to give approvals without a meeting shall be the date the first written approval is deposited with the Partnership in care of the General Partner in accordance with Section 13.11.

     Section 13.7 Adjournment. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed, if the time and place thereof are announced at the meeting at which the adjournment is taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII.

     Section 13.8 Waiver of Notice; Approval of Meeting; Approval of Minutes. The transactions of any meeting of Limited Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a waiver of any right to disapprove the consideration of matters required to be included in the notice of the meeting, but not so included, if the disapproval is expressly made at the meeting.

     Section 13.9 Quorum and Voting. Except as otherwise provided in this Agreement, the holders of a majority of the Outstanding Units of the class or classes for which a meeting has been called (including Outstanding Units deemed owned by the General Partner) represented in person or by proxy shall constitute a quorum at a meeting of Limited Partners of such class or classes unless any such action by the Limited Partners requires approval by holders of a greater percentage of such Units, in which case the quorum shall be such greater percentage. At any meeting of the Limited Partners duly called and held in accordance with this Agreement at which

a quorum is present, the act of Limited Partners holding Outstanding Units that in the aggregate represent a majority of the Outstanding Units entitled to vote and be present in person or by proxy at such meeting shall be deemed to constitute the act of all Limited Partners, unless a greater or different percentage is required with respect to such action under the provisions of this Agreement, applicable law, or the rules of an applicable National Securities Exchange, in which case the act of the Limited Partners holding Outstanding Units that in the aggregate represent at least such greater or different percentage shall be required. The Limited Partners present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough Limited Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by the required percentage of Outstanding Units specified in this Agreement (including Outstanding Units deemed owned by the General Partner). In the absence of a quorum any meeting of Limited Partners may be adjourned from time to time by the affirmative vote of holders of at least a majority of the Outstanding Units entitled to vote at such meeting (including Outstanding Units deemed owned by the General Partner) represented either in person or by proxy, but no other business may be transacted, except as provided in Section 13.7.

     Section 13.10 Conduct of a Meeting. The General Partner shall have full power and authority concerning the manner of conducting any meeting of the Limited Partners or solicitation of approvals in writing, including the determination of Persons entitled to vote, the existence of a quorum, the satisfaction of the requirements of Section 13.4, the conduct of voting, the validity and effect of any proxies and the determination of any controversies, votes or challenges arising in connection with or during the meeting or voting and adjournment of any meeting. The General Partner shall designate a Person to serve as chairman of any meeting and shall further designate a Person to take the minutes of any meeting. All minutes shall be kept with the records of the Partnership maintained by the General Partner. The General Partner may make such other regulations consistent with applicable law and this Agreement as it may deem advisable concerning the conduct of any meeting of the Limited Partners or solicitation of approvals in writing, including regulations in regard to the appointment of proxies, the appointment and duties of inspectors of votes and approvals, the submission and examination of proxies and other evidence of the right to vote, and the revocation of approvals in writing.

     Section 13.11 Action Without a Meeting. If authorized by the General Partner, any action that may be taken at a meeting of the Limited Partners may be taken without a meeting if an approval in writing setting forth the action so taken is signed by Limited Partners owning not less than the minimum percentage of the Outstanding Units (including Units deemed owned by the General Partner) that would be necessary to authorize or take such action at a meeting at which all the Limited Partners were present and voted (unless such provision conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall govern). Prompt notice of the taking of action without a meeting shall be given to the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot submitted to Limited Partners for the purpose of taking any action without a meeting shall be returned to the Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Units held by the Limited Partners, the

Partnership shall be deemed to have failed to receive a ballot for the Units that were not voted. If approval of the taking of any action by the Limited Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) they are deposited with the Partnership in care of the General Partner, (b) approvals sufficient to take the action proposed are dated as of a date not more than 90 days prior to the date sufficient approvals are deposited with the Partnership and (c) an Opinion of Counsel is delivered to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability, and (ii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the Partners.

     Section 13.12 Right to Vote and Related Matters.

     (a) Only those Record Holders of the Units on the Record Date set pursuant to Section 13.6 (and also subject to the limitations contained in the definition of “Outstanding”) shall be entitled to notice of, and to vote at, a meeting of Limited Partners or to act with respect to matters as to which the holders of the Outstanding Units have the right to vote or to act. All references in this Agreement to votes of, or other acts that may be taken by, the Outstanding Units shall be deemed to be references to the votes or acts of the Record Holders of such Outstanding Units.

     (b) With respect to Units that are held for a Person’s account by another Person (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), in whose name such Units are registered, such other Person shall, in exercising the voting rights in respect of such Units on any matter, and unless the arrangement between such Persons provides otherwise, vote such Units in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be entitled to assume it is so acting without further inquiry. The provisions of this Section 13.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3.

     Section 13.13 Board of Directors.

     (a) On or promptly after the GP Acquisition Date, the NGP Representative shall designate three members of the Board of Directors as Appointed Directors. As soon as reasonably practicable following the GP Acquisition Date, the Conflicts Committee shall appoint by a resolution adopted by a majority of the members of the Conflicts Committee, two additional Directors meeting the independence and experience requirements as set forth most recently by any National Securities Exchange on which any Units or other Partnership Securities are listed or quoted. The two additional Directors so appointed by the Conflicts Committee shall constitute Elected Directors. Following the appointment of such Directors, the Board of Directors shall consist of five Elected Directors, three Appointed Directors and one Management Director, subject to adjustment pursuant to Sections 13.13(d) or (e). The Directors shall be classified with respect to their terms of office by dividing them into three classes established pursuant to the limited liability company agreement of the General Partner (or the general partner thereof, as

applicable), each class to be as nearly equal in number as possible; provided, however, that no class shall contain more than one Appointed Director.

     (b) At each annual meeting of the Limited Partners held after the GP Acquisition Date, a number of individuals equal to the number of Elected Directors whose terms expire at such annual meeting (including any Elected Director whose term would have expired at such meeting but for the fact of such individual’s death, resignation or removal, unless the vacancy caused by such individual’s death, resignation or removal has already been filled prior to such annual meeting) shall be elected to hold office as Elected Directors until the third succeeding annual meeting. Each Elected Director shall hold office for the term for which such Elected Director is elected and thereafter until such Elected Director’s successor shall have been duly elected and qualified, or until such Elected Director’s earlier death, resignation or removal. Following the appointment by the Conflicts Committee of the two Elected Directors in accordance with Section 13.13(a), any vacancies in Elected Directors (whether due to death, resignation or removal of an Elected Director or an increase in the total number of Elected Directors in accordance with Section 13.13(e)) may be filled, until the next annual meeting at which the term of such class expires, by a majority of the remaining Elected Directors then in office.

Each Appointed Director shall hold office for the term for which such Appointed Director is appointed and thereafter until such Appointed Director’s successor shall have been duly appointed and qualified, or until such Appointed Director’s earlier death, resignation or removal. Any vacancies in Appointed Directors may be filled by the NGP Representative in its sole discretion. An Appointed Director may be removed (i) by the NGP Representative with or without Cause for Removal, (ii) for Cause for Removal upon a vote of the majority of the remaining Directors then in office, or (iii) in accordance with Section 13.13(e).

     (d) If, at any time, the NGP Parties collectively cease to be the Record Holders of 20% or more of the Outstanding Common Units (the “First NGP Voting Termination Event”), the Board of Directors may reduce the number of Appointed Directors to two by resolution adopted by of a majority of the Elected Directors. If, at any time, the NGP Parties collectively cease to be the Record Holders of 10% or more of the Outstanding Common Units (the “Second NGP Voting Termination Event”), the Board of Directors may reduce the number of Appointed Directors to one by resolution adopted by of a majority of the Elected Directors. If, at any time, the NGP Parties collectively cease to be the Record Holders of 5% or more of the Outstanding Common Units (the “Final NGP Voting Termination Event”), the Board of Directors may reduce the number of Appointed Directors to zero by resolution adopted by of a majority of the Elected

Directors. The NGP Representative shall notify the Board of Directors in writing as promptly as reasonably practicable following any NGP Voting Termination Event.

     (e) Upon the adoption of any resolution to reduce the number of Appointed Directors pursuant to Section 13.13(d), the Board of Directors by resolution adopted by a majority of the Elected Directors may elect (i) to remove a number of Appointed Directors up to the number of such reduction; provided that if not all Appointed Directors are removed pursuant to this clause (i) the NGP Representative shall be entitled to select which Appointed Director(s) are to be removed by providing written notice of such selection to the Board of Directors within five Business Days after the NGP Representative receives written notice of such resolution and/or (ii) to designate one or more of the Appointed Directors that would otherwise be removed pursuant to clause (i) above as an Elected Director(s) and to increase the total number of Elected Directors by the number of Appointed Directors that are so designated. Prior to the occurrence of the Final NGP Voting Termination Event, except as contemplated by this Section 13.13(e), the total number of Elected Directors shall not exceed five without the approval of the Board of Directors by resolution adopted by a majority of the Elected Directors and the written consent of the NGP Representative. Following the Final NGP Voting Termination Event, the total number of Elected Directors shall be as established from time to time by the Board of Directors.

     (f) Prior to the Final NGP Voting Termination Event, the Chief Executive Officer of the General Partner (or the general partner thereof, as applicable) (or his designee) shall serve as a Director (the “Management Director”) until such Chief Executive Officer’s successor shall have been duly appointed, or until such Chief Executive Officer’s earlier death, resignation or removal. Immediately following the Final NGP Voting Termination Event, the Management Director shall be redesignated as an Elected Director under this Agreement and after such redesignation, this Section 13.13(f) shall have no effect.

     (g) This Article XIII shall not be deemed in any way to limit or impair the ability of the Board of Directors or the General Partner to adopt a “poison pill” or unitholder or other similar rights plan with respect to the Partnership, whether such poison pill or plan contains “dead hand” provisions, “no hand” provisions or other provisions relating to the redemption of the poison pill or plan, in each case as such terms are used under Delaware common law.

     (h) The General Partner shall use its reasonable efforts to take such action as shall be necessary or appropriate to give effect to and implement the provisions of this Section 13.13, including, without limitation, amending the limited partnership agreement of the General Partner and the limited liability company agreement of the general partner of the General Partner.

     (a) Notwithstanding any other provision of this Agreement, if at any time prior to the consummation of the GP Acquisition the General Partner and its Affiliates hold more than 80% of the total Limited Partner Interests of any class then Outstanding, the General Partner shall then have the right, which right it may assign and transfer in whole or in part to the Partnership or any Affiliate of the General Partner, exercisable at its option, to purchase all, but not less than all, of such Limited Partner Interests of such class then Outstanding held by Persons other than the General Partner and its Affiliates, at the greater of (x) the Current Market Price as of the date three days prior to the date that the notice described in Section 15.1(b) is mailed and (y) the highest price paid by the General Partner or any of its Affiliates for any such Limited Partner Interest of such class purchased during the 90-day period preceding the date that the notice described in Section 15.1(b) is mailed. Any right to acquire Limited Partner Interests pursuant to this Section 15.1 shall automatically terminate upon the consummation of the GP Acquisition. As used in this Agreement, (i) “Current Market Price” as of any date of any class of Limited Partner Interests means the average of the daily Closing Prices (as hereinafter defined) per Limited Partner Interest of such class for the 20 consecutive Trading Days (as hereinafter defined) immediately prior to such date; (ii) “Closing Price” for any day means the last sale price on such day, regular way, or in case no such sale takes place on such day, the average of the closing bid and asked prices on such day, regular way, as reported in the principal consolidated transaction reporting system with respect to securities listed on the principal National Securities

Exchange (other than the Nasdaq Stock Market) on which such Limited Partner Interests are listed or admitted to trading or, if such Limited Partner Interests of such class are not listed or admitted to trading on any National Securities Exchange (other than the Nasdaq Stock Market), the last quoted price on such day or, if not so quoted, the average of the high bid and low asked prices on such day in the over-the-counter market, as reported by the Nasdaq Stock Market or such other system then in use, or, if on any such day such Limited Partner Interests of such class are not quoted by any such organization, the average of the closing bid and asked prices on such day as furnished by a professional market maker making a market in such Limited Partner Interests of such class selected by the General Partner, or if on any such day no market maker is making a market in such Limited Partner Interests of such class, the fair value of such Limited Partner Interests on such day as determined by the General Partner; and (iii) “Trading Day” means a day on which the principal National Securities Exchange on which such Limited Partner Interests of any class are listed or admitted for trading is open for the transaction of business or, if Limited Partner Interests of a class are not listed or admitted for trading on any National Securities Exchange, a day on which banking institutions in New York City generally are open.

     (b) If the General Partner, any Affiliate of the General Partner or the Partnership elects to exercise the right to purchase Limited Partner Interests granted pursuant to Section 15.1(a), the General Partner shall deliver to the Transfer Agent notice of such election to purchase (the “Notice of Election to Purchase”) and shall cause the Transfer Agent to mail a copy of such Notice of Election to Purchase to the Record Holders of Limited Partner Interests of such class (as of a Record Date selected by the General Partner) at least 10, but not more than 60, days prior to the Purchase Date. Such Notice of Election to Purchase shall also be published for a period of at least three consecutive days in at least two daily newspapers of general circulation printed in the English language and published in the Borough of Manhattan, New York. The Notice of Election to Purchase shall specify the Purchase Date and the price (determined in accordance with Section 15.1(a)) at which Limited Partner Interests will be purchased and state that the General Partner, its Affiliate or the Partnership, as the case may be, elects to purchase such Limited Partner Interests, upon surrender of Certificates representing such Limited Partner Interests in exchange for payment, at such office or offices of the Transfer Agent as the Transfer Agent may specify, or as may be required by any National Securities Exchange on which such Limited Partner Interests are listed. Any such Notice of Election to Purchase mailed to a Record Holder of Limited Partner Interests at his address as reflected in the records of the Transfer Agent shall be conclusively presumed to have been given regardless of whether the owner receives such notice. On or prior to the Purchase Date, the General Partner, its Affiliate or the Partnership, as the case may be, shall deposit with the Transfer Agent cash in an amount sufficient to pay the aggregate purchase price of all of such Limited Partner Interests to be purchased in accordance with this Section 15.1. If the Notice of Election to Purchase shall have been duly given as aforesaid at least 10 days prior to the Purchase Date, and if on or prior to the Purchase Date the deposit described in the preceding sentence has been made for the benefit of the holders of Limited Partner Interests subject to purchase as provided herein, then from and after the Purchase Date, notwithstanding that any Certificate shall not have been surrendered for purchase, all rights of the holders of such Limited Partner Interests (including any rights pursuant to Article IV, Article V, Article VI, and Article XII) shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 15.1(a)) for Limited Partner Interests therefor, without interest, upon surrender to the Transfer Agent of the Certificates

representing such Limited Partner Interests, and such Limited Partner Interests shall thereupon be deemed to be transferred to the General Partner, its Affiliate or the Partnership, as the case may be, on the record books of the Transfer Agent and the Partnership, and the General Partner or any Affiliate of the General Partner, or the Partnership, as the case may be, shall be deemed to be the owner of all such Limited Partner Interests from and after the Purchase Date and shall have all rights as the owner of such Limited Partner Interests (including all rights as owner of such Limited Partner Interests pursuant to Article IV, Article V, Article VI and Article XII).

     (c) At any time from and after the Purchase Date, a holder of an Outstanding Limited Partner Interest subject to purchase as provided in this Section 15.1 may surrender his Certificate evidencing such Limited Partner Interest to the Transfer Agent in exchange for payment of the amount described in Section 15.1(a), therefor, without interest thereon.

EAGLE ROCK ENERGY PARTNERS, L.P.

     This Warrant Certificate certifies that [                    ], or registered assigns, is the registered holder of Warrants (the “Warrants”) expiring [                    ], 2012¹ (the “Expiration Date”) to purchase common units representing limited partner interests (the “Common Units”) of Eagle Rock Energy Partners, L.P., a Delaware limited partnership (the “Partnership”).

     No fraction of a Common Unit will be issued upon any exercise of a Warrant. If the holder of a Warrant would be entitled to receive a fraction of a Common Unit upon any exercise of a Warrant, the Partnership shall, upon such exercise, round up or down to the nearest whole number the number of Common Units to be issued to such holder.

     Upon any exercise of the Warrant for less than the total number of Warrant Units provided for herein, there shall be issued to the registered holder or the registered holder’s assignee a new Warrant Certificate covering the number of Warrant Units for which the Warrant has not been exercised.

     Warrant Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder hereof in person or by attorney duly authorized in writing, may be exchanged in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or

Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants.³

     The Partnership and the Warrant Agent may deem and treat the registered holder as the absolute owner of this Warrant Certificate (notwithstanding any notification of ownership or other writing hereon made by anyone) for the purpose of any exercise hereof, of any distribution to the registered holder, and for all other purposes, and neither the Partnership nor the Warrant Agent shall be affected by any notice to the contrary.

     This Warrant Certificate does not entitle the registered holder to any of the rights of a unitholder of the Partnership.

     This Warrant Certificate shall not be valid unless countersigned by the Warrant Agent.

SUMMARY OF CERTAIN TERMS OF WARRANT AGREEMENT

The Warrant Agreement shall contain the following terms, together with such other terms reasonably agreed to by the Partnership and the warrant agent:

1. Exercise of Warrants.

     Warrants may be exercised at any time from 9:00 a.m. until 5:00 p.m. New York City Time on each of the Exercise Dates prior to the Expiration Date. In order to exercise all or any of the Warrants represented by this Warrant Certificate, the holder must deliver this Warrant Certificate and the form of election to purchase duly filled in and signed, which signature shall be medallion guaranteed by an institution which is a member of a Securities Transfer Association recognized signature guarantee program, and upon payment to the Warrant Agent for the account of the Partnership of the Exercise Price, as adjusted as provided herein, for the number of Warrant Units in respect of which such Warrants are then exercised.

2. Certain Adjustments.

     The Exercise Price and number of Warrant Units issuable upon exercise of the Warrants will be subject to adjustment from time to time.

     Unit Distributions and Splits. If the Partnership, at any time while the Warrants are outstanding, (i) makes a distribution on its Common Units that is payable in Common Units, (ii) subdivides outstanding Common Units into a larger number, or (iii) combines outstanding Common Units into a smaller number, then in each such case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of Common Units outstanding immediately before such event and of which the denominator shall be the number of Common Units outstanding immediately after such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of unitholders entitled to receive such distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. Simultaneously with any adjustment to the Exercise Price pursuant to this paragraph, the number of Warrant Units that may be purchased upon exercise of a Warrant shall be increased or decreased proportionately, as applicable, so that after such adjustment the aggregate Exercise Price payable hereunder for the Warrant Units shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment.

     Fundamental Transaction. If, at any time while the Warrants are outstanding, (A) the Partnership effects any merger or consolidation of the Partnership with or into (whether or not the Partnership is the surviving entity) another person or (B) the Partnership effects any sale, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, in each of cases (A) and (B) above, pursuant to which the Common Units are effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of Common Units described above) (in any such case, a “Fundamental Transaction”), then the holder shall have the right thereafter to receive, upon exercise of

a Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Units then issuable upon exercise in full of this Warrant Certificate.

     Calculations. All calculations shall be made to the nearest cent. If a distribution, subdivision or combination of Common Units would otherwise result in the issuance of fractional Warrant Units, each fractional Warrant Unit shall be rounded up or down to the nearest whole Warrant Unit.

     Notice of Adjustments. Upon the occurrence of each adjustment, the Partnership at its expense will promptly compute such adjustment in accordance with the terms of this Warrant Certificate and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Units or other securities issuable upon exercise of the Warrants (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. The Partnership will promptly deliver a copy of each such certificate to the Warrant Agent.

3. Global Certificates; Exchanges.

     The Warrant Agreement shall provide for a global warrant certificate to be held by the Depositary Trust Company (or its designee). The global certificate shall be subject to customary exchange, transfer and registration provisions.

4. Amendments and Modifications.

     The Partnership may, without the consent of the holders, by supplemental agreement or otherwise, make any changes or corrections in the Warrant Certificate or the Warrant Agreement that are required to cure any ambiguity or to correct or supplement any provision herein which may be defective or inconsistent with any other provision herein; provided that such changes or corrections shall not adversely affect the interests of holders of then outstanding Warrants in any material respect. The Warrant Certificate and the Warrant Agreement may also be amended or waived with the consent of the Partnership and the holder. Further, the Partnership may, with the consent, in writing or at a meeting, of the holders of the then outstanding Warrants exercisable for a majority or greater of the Common Units issuable under such Warrants at that time, amend in any way, by supplemental agreement or otherwise, the Warrant Certificate and/or all of the outstanding Warrants; provided, however, that (i) no such amendment by its express terms shall adversely affect any holder differently than it affects all other holders, unless such adversely affected holder consents thereto, and (ii) no such amendment concerning the number of Warrant Units or Exercise Price shall be made unless any holder who will be affected by such amendment consents thereto.
