ARTICLE I

THE MERGER

Section 1.1 The Merger. At the Effective Time, upon the terms and subject to the conditions set forth in this Agreement and in accordance with the applicable provisions of the Delaware Revised Uniform Limited Partnership Act (“DRULPA”) and the Delaware Limited Liability Company Act (“DLLCA”), Merger Sub shall be merged with and into the Partnership, whereupon the separate existence of Merger Sub shall cease, and the Partnership shall continue as the surviving entity in the Merger (the “Surviving Entity”).

Section 1.2 Closing. The closing of the Merger (the “Closing”) shall take place at the offices of ▇▇▇▇▇ ▇▇▇▇▇ L.L.P. at ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ at 10:00 a.m., local time, on a date to be specified by the parties (the “Closing Date”) which shall be no later than the third Business Day after the satisfaction or waiver (to the extent permitted by applicable Law) of the conditions set forth in Article VI (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), or at such other place, date and time as the Partnership and Parent may agree in writing.

Section 1.3 Effective Time. At the Closing, the Partnership shall cause the Merger to be consummated by executing and filing a certificate of merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware in accordance with Section 17-211 of the DRULPA and Section 18-209 of the DLLCA. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such later date or time as may be agreed by Parent and the Partnership in writing and specified in the Certificate of Merger in accordance with the DRULPA and the DLLCA (such time as the Merger becomes effective is referred to herein as the “Effective Time”).

Section 1.4 Effects of the Merger. The Merger shall have the effects set forth in this Agreement, the Partnership Agreement and the applicable provisions of the DRULPA and DLLCA.

Section 1.5 Partnership Agreement of the Surviving Entity. The Partnership Agreement, as in effect immediately prior to the Effective Time, shall remain the partnership agreement of the Surviving Entity and shall continue in effect until thereafter changed or amended in accordance with the provisions thereof and applicable Law.

Section 1.6 Admission of Additional Limited Partners. Upon the conversion of the limited liability company interests in Merger Sub (“Merger Sub LLC Interests”), which are denominated in units (“Merger Sub LLC Units”), into Common Units pursuant to Section 2.1(c) and the recording of the name of the holder thereof as a limited partner of the Partnership on the books and records of the Partnership, such Person shall automatically and effective as of the Effective Time be admitted to the Partnership as an additional Limited Partner and be bound by the Partnership Agreement as such.

ARTICLE II

CONVERSION OF PARTNERSHIP INTERESTS; EXCHANGE OF CERTIFICATES

Section 2.1 Effect on Partnership Interests. At the Effective Time, by virtue of the Merger and without any action on the part of the Partnership, Merger Sub or the holders of any securities of the Partnership or Merger Sub:

(a) Conversion of Common Units. Subject to Sections 2.1(b) and 2.1(d), each Common Unit issued and outstanding immediately prior to the Effective Time, other than any Common Units included among the Rollover Interests, shall thereupon be converted automatically into and shall thereafter represent the right to receive $7.75 in cash without any interest thereon (the “Merger Consideration”). Immediately prior to the Effective Time, each award of Restricted Units (as defined in the ▇▇▇▇▇▇ Partners, LP Long-Term Incentive Plan (the “▇▇▇▇▇▇ LTIP”)) issued and outstanding to any nonemployee member of the Board of Directors shall become fully vested as Common Units and shall thereupon be converted automatically into and shall thereafter represent the right to receive the Merger Consideration. All Common Units that have been converted into the right to receive the Merger Consideration as provided in this Section 2.1 shall be automatically cancelled and shall cease to exist, and the holders of such Common Units immediately prior to the Effective Time (whether certificated or non-certificated and represented in book-entry form) shall cease to have any rights with respect to such Common Units other than the right to receive the Merger Consideration.

(b) Rollover of Certain Partnership Interests. The following Partnership Interests shall be treated in the Merger as follows:

(i) each of the 2,321,471 Common Units owned by Holdings shall be unchanged and remain outstanding as Common Units of the Surviving Entity, and no consideration shall be delivered in respect thereof;

(ii) each of the 3,060,000 Subordinated Units owned by Holdings shall be unchanged and remain outstanding as Subordinated Units of the Surviving Entity, and no consideration shall be delivered in respect thereof;

(iii) the General Partner Interest, which is represented by 190,814 General Partner Units and is owned by Partnership GP, shall be unchanged and remain outstanding as the General Partner Interest of the Surviving Entity, and no consideration shall be delivered in respect thereof; and

(iv) the Incentive Distribution Rights, which are owned by Partnership GP, shall be unchanged and remain outstanding as Incentive Distribution Rights of the Surviving Entity, and no consideration shall be delivered in respect thereof.

The Partnership Interests described in this Section 2.1(b) are referred to in this Agreement as “Rollover Interests,” and the record and beneficial owners of such Rollover Interests are referred to in this Agreement as the “Rollover Parties.”

(c) Conversion of Merger Sub Limited Liability Company Interests. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each Merger Sub LLC Unit issued and outstanding immediately prior to the Effective Time shall be converted into and become one Common Unit of the Surviving Entity, which Common Units shall be duly authorized and validly issued in accordance with applicable Laws and the Partnership Agreement and shall be fully paid (to the extent required by the Partnership Agreement) and nonassessable (except to the extent such nonassessability may be affected by Sections 17-607 and 17-804 of DRULPA). Immediately after the Effective Time, such Common Units and the Rollover Interests will constitute the only outstanding Partnership Interests of the Surviving Entity. From and after the Effective Time, any certificates or other evidence representing the Merger Sub LLC Units shall be deemed for all purposes to represent the number of Common Units of the Surviving Entity into which such Merger Sub LLC Units were converted in accordance with this Section 2.1(c). Partnership GP hereby agrees and acknowledges that conversion of the Merger Sub LLC Units to Common Units of the Surviving Entity as provided herein shall constitute a duly authorized, accepted, executed and countersigned delivery of such Common Units, without any further action by Partnership GP or any other person.

(d) Adjustments. If between the date of this Agreement and the Effective Time, the outstanding Common Units, including securities convertible or exchangeable into or exercisable for Common Units, shall be changed into a different number of units or other securities by reason of any split, combination, merger, consolidation, reorganization, reclassification, recapitalization or other similar transaction, or any distribution payable in Partnership Interests shall be declared thereon with a record date within such period, the Merger Consideration shall be appropriately adjusted to provide the holders of Common Units the same economic effect as contemplated by this Agreement prior to such event; provided that nothing herein shall be construed to permit the Partnership to take any action with respect to its securities that is expressly prohibited by the terms of this Agreement.

Section 2.2 Exchange of Certificates.

(a) Paying Agent. Prior to the mailing of the Proxy Statement (as defined herein), Parent shall appoint a U.S. bank or trust company agreeable to the Conflicts Committee to act as paying agent (the “Paying Agent”) for the holders of Common Units (other than the Rollover Parties) in connection with the Merger and to receive and pay out the Merger

Consideration to which such holders shall become entitled pursuant to Section 2.1. At or prior to the Effective Time, the Parent Parties shall deposit, or shall cause to be deposited, in trust with the Paying Agent, for the benefit of holders of Common Units (other than the Rollover Parties), cash in an amount sufficient to pay the aggregate Merger Consideration in exchange for all Common Units outstanding immediately prior to the Effective Time (other than Common Units included among the Rollover Interests), payable upon due surrender of the certificates that immediately prior to the Effective Time represented Common Units (“Certificates”) (or effective affidavits of loss in lieu thereof) or non-certificated Common Units represented in book-entry form (“Book-Entry Common Units”) pursuant to the provisions of this Article II (such cash hereinafter referred to as the “Exchange Fund”).

(b) Payment Procedures.

(i) As soon as reasonably practicable after the Effective Time and in any event not later than the fifth Business Day following the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of Common Units whose Common Units were converted into the Merger Consideration pursuant to Section 2.1(a), (A) a letter of transmittal (the “Letter of Transmittal”) (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates (or effective affidavits of loss in lieu thereof) to the Paying Agent or, in the case of Book-Entry Common Units, upon adherence to the procedures set forth in the Letter of Transmittal, and shall be in such customary form and have such other provisions as Parent and the ▇▇▇▇▇▇ Parties shall reasonably determine) and (B) instructions for use of the Letter of Transmittal in effecting the surrender of the Certificates (or effective affidavits of loss in lieu thereof) or Book-Entry Common Units in exchange for the Merger Consideration.

(ii) Upon surrender of a Certificate (or an effective affidavit of loss in lieu thereof) or Book-Entry Common Units to the Paying Agent together with such Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may customarily be required by the Paying Agent, the holder of such Certificate or Book-Entry Common Units shall be entitled to receive in exchange therefor a check in an amount equal to the product of (x) the number of Common Units represented by such holder’s properly surrendered Certificates (or effective affidavits of loss in lieu thereof) or Book-Entry Common Units multiplied by (y) the Merger Consideration. No interest shall be paid or accrued for the benefit of holders of the Certificates or Book-Entry Common Units on the Merger Consideration payable in respect of the Certificates or Book-Entry Common Units. In the event of a transfer of ownership of Common Units that is not registered in the unit transfer register of the Partnership, a check for any cash to be paid upon due surrender of the Certificate may be paid to such a transferee if the Certificate formerly representing such Common Units is presented to the Paying Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable unit transfer or other Taxes have been paid or are not applicable.

(iii) Parent, the Surviving Entity and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable under this Agreement to any holder of Common Units such amounts as are required to be withheld or deducted under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of federal, state,

local or foreign Tax Law with respect to the making of such payment. To the extent that amounts are so withheld or deducted and paid over to the applicable Governmental Entity, such withheld or deducted amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Common Units in respect of which such deduction and withholding were made.

(c) Closing of Transfer Register. At the Effective Time, the unit transfer register of the Partnership shall be closed, and there shall be no further registration of transfers on the unit transfer register of the Surviving Entity of Common Units (other than the Rollover Interests) that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Common Units provided for in Section 2.1(a) are presented to the Surviving Entity or Parent for transfer, they shall be cancelled and exchanged for a check in the proper amount pursuant to and subject to the requirements of this Article II.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains undistributed to the former holders of Common Units for twelve months after the Effective Time shall be delivered to the Surviving Entity upon demand, and any former holders of Common Units who have not surrendered their Certificates or Book-Entry Common Units provided for in Section 2.1(a) in accordance with this Section 2.2 shall thereafter look only to the Surviving Entity for payment of their claim for the Merger Consideration, without any interest thereon, upon due surrender of their Certificates or Book-Entry Common Units.

(e) No Liability. Notwithstanding anything herein to the contrary, none of Parent, Merger Sub, the Partnership, Partnership GP, the Surviving Entity, the Paying Agent or any other person shall be liable to any former holder of Common Units for any amount properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(f) Investment of Exchange Fund. The Paying Agent shall invest the Exchange Fund as reasonably directed by Parent; provided, however, that any investment of such Exchange Fund shall be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government and that no such investment or loss thereon shall affect the amounts payable to holders of Common Units that converted into the right to receive the Merger Consideration pursuant to Section 2.1. Any interest and other income resulting from such investments shall be paid to the Surviving Entity pursuant to Section 2.2(d).

(g) Lost Certificates. In the event that any Certificate representing Common Units provided for in Section 2.1(a) shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Paying Agent, the posting by such person of a bond in customary amount as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will issue in exchange for such lost, stolen or destroyed Certificate a check in the amount of the number of Common Units represented by such lost, stolen or destroyed Certificate multiplied by the Merger Consideration.

Section 2.3 Timing for Rollover Interests. For the avoidance of doubt, the parties acknowledge and agree that the Rollover Commitments shall be deemed to become effective and irrevocable immediately prior to the Effective Time and prior to any other event described above in this Article II.

ARTICLE III

No information or knowledge obtained by Parent in any investigation pursuant to this Section 5.2 shall affect or be deemed to modify any representation or warranty made by the ▇▇▇▇▇▇ Parties in Article III or any condition set forth in Article VI.

Section 5.3 No Solicitation.

(a) Subject to Sections 5.3(b)-(h), the ▇▇▇▇▇▇ Parties shall not and shall cause their officers, directors, employees, agents and representatives (“Representatives”) not to, and shall use their reasonable best efforts to cause each of the other ▇▇▇▇▇▇ Group Entities and their Representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage (including by providing information) or knowingly facilitate any inquiries, proposals or offers with respect to, or the making or completion of, an Alternative Proposal (as defined herein), (ii) engage or participate in any negotiations concerning, or provide or cause to be provided any non-public information or data relating to, the ▇▇▇▇▇▇ Group Entities, in connection with, or have any discussions with any person relating to, an Alternative Proposal, or otherwise knowingly encourage or knowingly facilitate any effort or attempt to make or implement an Alternative Proposal, (iii) approve, endorse or recommend, or propose publicly to approve, endorse or recommend, any Alternative Proposal, (iv) approve, endorse or recommend, or propose to approve, endorse or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to any Alternative Proposal, (v) amend, terminate, waive or fail to enforce, or grant any consent under, any confidentiality, standstill or similar agreement, (vi) take, encourage or facilitate any action that Section 5.3(a) of the Holdings Agreement would prohibit if the ▇▇▇▇▇▇ Parties were the “Holdings Parties,” as such term is defined and used therein, or (vii) resolve to propose or agree to do any of the foregoing.

(b) The ▇▇▇▇▇▇ Parties shall and shall cause their Representatives to, and shall use their reasonable best efforts to cause each of the other ▇▇▇▇▇▇ Group Entities and their Representatives to, immediately cease any existing solicitations, discussions or negotiations with any Person (other than the parties hereto) that has made or indicated an intention to make an Alternative Proposal. The ▇▇▇▇▇▇ Parties shall promptly, and in any event not later than ten (10) days following the date hereof, request that each Person who has executed a confidentiality agreement with a ▇▇▇▇▇▇ Party in connection with that Person’s consideration of a transaction involving any ▇▇▇▇▇▇ Group Entity that would constitute an Alternative Proposal return or

destroy all non-public information furnished to that Person by or on behalf of the ▇▇▇▇▇▇ Group Entities.

(c) Notwithstanding anything to the contrary in Section 5.3(a), prior to the receipt of Unitholder Approval, the ▇▇▇▇▇▇ Parties may, in response to an unsolicited Alternative Proposal which did not result from or arise in connection with a breach of this Section 5.3 and which the Conflicts Committee determines, in good faith, after consultation with its outside counsel and financial advisors, constitutes or could reasonably be expected to result in a Superior Proposal (as defined herein), (i) furnish information with respect to the ▇▇▇▇▇▇ Group Entities to the person making such Alternative Proposal and its Representatives pursuant to an executed confidentiality agreement no less restrictive (including with respect to standstill provisions) of the other party than the Confidentiality Agreement and (ii) participate in discussions or negotiations with such person and its Representatives regarding such Alternative Proposal; provided, however, (A) that Parent shall be entitled to receive an executed copy of such confidentiality agreement prior to or substantially simultaneously with the ▇▇▇▇▇▇ Parties furnishing information to the person making such Alternative Proposal or its Representatives and (B) that the ▇▇▇▇▇▇ Parties shall simultaneously provide or make available to Parent any non-public information concerning the ▇▇▇▇▇▇ Group Entities that is provided to the person making such Alternative Proposal or its Representatives which was not previously provided or made available to Parent. Notwithstanding anything to the contrary in Section 5.3(a), prior to the receipt of Unitholder Approval, the ▇▇▇▇▇▇ Parties may participate in discussions or negotiations with the lenders under the ▇▇▇▇▇▇ Operating Credit Agreement regarding debt financing transactions with such lenders that may involve equity issuances that would constitute an Alternative Proposal and, in connection therewith, furnish information with respect to the ▇▇▇▇▇▇ Group Entities to such lenders pursuant to confidentiality obligations substantially consistent with past practice.

(d) Neither the Board of Directors nor any committee thereof shall withdraw, modify or qualify in a manner adverse to Parent, or resolve to or publicly propose to withdraw, modify or qualify in a manner adverse to Parent, the Recommendation (any of the foregoing actions, whether taken by the Board of Directors or any committee thereof, a “Change in Board Recommendation”). Notwithstanding the immediately preceding sentence, if, prior to receipt of the Unitholder Approval, (i) the Board of Directors or the Conflicts Committee determines in good faith, after consultation with its respective outside counsel and financial advisors, that a Change in Board Recommendation would be in the best interests of the holders of Common Units (other than Partnership GP and its Affiliates (including Holdings)) and (ii) the Board of Directors or the Conflicts Committee, as applicable, provides Parent with at least three (3) Business Days’ advance written notice of its intention to make a Change in Board Recommendation and specifying the material events giving rise thereto, then the Board of Directors or the Conflicts Committee, as applicable, may make a Change in Board Recommendation.

(e) The ▇▇▇▇▇▇ Parties promptly (and in any event within 24 hours) shall advise Parent orally and in writing of the receipt by either of them of (i) any Alternative Proposal or (ii) any request for non-public information relating to the ▇▇▇▇▇▇ Group Entities, other than requests for information in the ordinary course of business consistent with past practice and not reasonably expected to be related to an Alternative Proposal, including in each case the identity

of the person making any such Alternative Proposal or request and the material terms and conditions of any such Alternative Proposal or request (including copies of any document or correspondence evidencing such Alternative Proposal or request). The ▇▇▇▇▇▇ Parties shall keep Parent reasonably informed on a current basis of the status (including any material change to the terms thereof) of any such Alternative Proposal or request.

(f) Nothing contained in this Agreement shall prohibit the ▇▇▇▇▇▇ Parties or the Board of Directors or any committee thereof from disclosing to the Partnership’s Unitholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided, however, that none of the ▇▇▇▇▇▇ Parties or the Board of Directors or any committee thereof shall in any event be entitled to disclose a position under Rules 14d-9 or 14e-2(a) promulgated under the Exchange Act other than the Recommendation, except in accordance with Section 5.3(d).

(g) As used in this Agreement, “Alternative Proposal” shall mean any inquiry, proposal or offer from any Person or group of Persons other than the Parent Parties, relating to, or that could reasonably be expected to lead to, in one transaction or a series of related transactions, (i) a merger, tender or exchange offer, consolidation, reorganization, reclassification, recapitalization, liquidation or dissolution, or other business combination involving any ▇▇▇▇▇▇ Group Entity, (ii) the issuance by the Partnership of (A) any General Partner Interest or (B) any class of Partnership Interests constituting more than 15% of such class of Partnership Interests or (iii) the acquisition in any manner, directly or indirectly, of (A) any General Partner Interest, (B) any class of Partnership Interests constituting more than 15% of such class of Partnership Interests or (C) more than 15% of the consolidated total assets of the ▇▇▇▇▇▇ Group Entities (including equity interests in any Subsidiary or Partially Owned Entity of the Partnership), in each case other than the Merger and the Holdings Merger.

(h) As used in this Agreement, “Superior Proposal” shall mean any written Alternative Proposal (i) on terms which the Conflicts Committee determines in good faith, after consultation with its outside legal counsel and financial advisors, to be more favorable from a financial point of view to the holders of Common Units (other than Partnership GP and its Affiliates (including Holdings)) (excluding consideration of any interests that any holder may have other than as a Unitholder of the Partnership entitled to the Merger Consideration) than the Merger, taking into account all the terms and conditions of such proposal, and this Agreement (including any proposal or offer by the Parent Parties to amend the terms of this Agreement and the Merger) and (ii) that is reasonably capable of being completed, taking into account all financial, regulatory, legal and other aspects of such proposal; provided that for purposes of the definition “Superior Proposal,” the references to “15%” in the definition of “Alternative Proposal” shall be deemed to be references to “55%.”

Section 5.4 Filings; Other Actions.

(a) As promptly as reasonably practicable following the date of this Agreement, the ▇▇▇▇▇▇ Parties shall prepare the Proxy Statement, which shall, subject to Section 5.3(d), include the Recommendation, and the ▇▇▇▇▇▇ Parties and Parent shall prepare the Schedule 13E-3.

reasonable efforts to have the Proxy Statement, and Parent and the ▇▇▇▇▇▇ Parties will use their commercially reasonable efforts to have the Schedule 13E-3, cleared by the SEC as promptly as practicable after such filing. The ▇▇▇▇▇▇ Parties will use their commercially reasonable efforts to cause the Proxy Statement to be mailed to the Partnership’s Unitholders as promptly as practicable after the Proxy Statement is cleared by the SEC. The ▇▇▇▇▇▇ Parties shall as promptly as practicable notify Parent of the receipt of any oral or written comments from the SEC relating to the Proxy Statement or Schedule 13E-3. The ▇▇▇▇▇▇ Parties shall cooperate and provide Parent with a reasonable opportunity to review and comment on the draft of the Proxy Statement (including each amendment or supplement thereto), which comments shall be considered reasonably and in good faith by the ▇▇▇▇▇▇ Parties, and Parent and the ▇▇▇▇▇▇ Parties shall cooperate and provide each other with a reasonable opportunity to review and comment on the draft Schedule 13E-3 (including each amendment or supplement thereto), which comments shall be considered reasonably and in good faith by the other party, and all responses to requests for additional information by and replies to comments of the SEC, prior to filing such with or sending such to the SEC, and Parent and the ▇▇▇▇▇▇ Parties will provide each other with copies of all such filings made and correspondence with the SEC with respect thereto. If at any time prior to the Effective Time, any information should be discovered by any party hereto which should be set forth in an amendment or supplement to the Proxy Statement or the Schedule 13E-3 so that the Proxy Statement or the Schedule 13E-3 would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and, to the extent required by applicable Law, an appropriate amendment or supplement describing such information shall be promptly filed by the ▇▇▇▇▇▇ Parties with the SEC and disseminated by the ▇▇▇▇▇▇ Parties to the Unitholders of the Partnership.

Notwithstanding anything in this Agreement to the contrary, unless this Agreement is terminated in accordance with Article VII, the ▇▇▇▇▇▇ Parties will take all of the actions contemplated by this Section 5.4 regardless of whether there has been a Change in Board Recommendation, and shall direct that this Agreement be submitted to a vote of Unitholders in accordance with the requirements of Articles XIII and XIV of the Partnership Agreement.

Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 5.6 shall limit a party’s right to terminate this Agreement pursuant to Section 7.1(b)(i) or (ii) so long as such party has, prior to such termination, complied with its obligations under this Section 5.6.

(d) The Parent Parties and the ▇▇▇▇▇▇ Parties may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 5.6 as “Regulatory Counsel Only Material.” Such materials and the information contained therein shall be given only to the outside regulatory counsel of the recipient and will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express written permission is obtained in advance from the source of the materials (the Parent Parties or the ▇▇▇▇▇▇ Parties as the case may be) or its legal counsel. Notwithstanding anything to the contrary in this Section 5.6, materials provided to the other party or its outside counsel may be redacted to remove references concerning the valuation of the Common Units or the business of the ▇▇▇▇▇▇ Group Entities.

(b) For a period of six years after the Effective Time, Parent and Partnership GP shall, and Parent and Partnership GP shall cause the Surviving Entity (and its successors or assigns) to, maintain officers’ and directors’ liability insurance covering each person who is immediately prior to the Effective Time, or has been at any time prior to the Effective Time, an officer or director of any of the ▇▇▇▇▇▇ Group Entities and each person who immediately prior to the Effective Time is serving or prior to the Effective Time has served at the request of any of the ▇▇▇▇▇▇ Group Entities as a director, officer, trustee or fiduciary of another corporation, partnership, joint venture, trust, pension or other Employee Benefit Plan of the ▇▇▇▇▇▇ Group Entities (collectively, the “▇▇▇▇▇▇ D&O Indemnified Parties”) who are or at any time prior to the Effective Time were covered by the existing officers’ and directors’ liability insurance applicable to the ▇▇▇▇▇▇ Group Entities (“D&O Insurance”) on terms substantially no less advantageous to the ▇▇▇▇▇▇ D&O Indemnified Parties than such existing insurance with respect to acts or omissions, or alleged acts or omissions, prior to the Effective Time (whether claims, actions or other proceedings relating thereto are commenced, asserted or claimed before or after the Effective Time).

(c) The Partnership shall cause (and Parent, following the Closing, shall continue to cause) coverage to be extended under the D&O Insurance by obtaining a six-year “tail” policy on terms and conditions no less advantageous than the existing D&O Insurance, and such “tail” policy shall satisfy the provisions of this Section 5.9; provided that in no event shall Parent be required to spend more than 250% (the “Cap Amount”) of the last annual premium
