ARTICLE 2

CONVERSION OF EQUITY INTERESTS; ELECTION PROCEDURES

Section 2.1 Effect of the Merger on Equity Interests in the Company. At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Merger Sub or the holders of any equity interests of the Company or Merger Sub:

(a) Conversion of Common Units. Subject to Section 2.1(e), each Common Unit issued and outstanding immediately prior to the Effective Time shall thereupon be converted automatically into and shall thereafter represent the right to receive the following consideration (the “Common Unit Consideration”):

(i) each Common Unit (including each Phantom Unit) with respect to which an election to receive all cash (a “Cash Election”) has been effectively made and not revoked pursuant to Section 2.2 and each Non-Electing Common Unit shall be converted into the right to receive $8.15 in cash without interest; and

(ii) each Common Unit (including each Phantom Unit) with respect to which an election to receive a combination of stock and cash (a “Mixed Election”) has been effectively made and not revoked pursuant to Section 2.2 shall be converted into the right to receive (A) $4.075 per Common Unit in cash without interest, and (B) a fraction of a validly issued, fully paid and nonassessable Parent Share equal to the quotient determined

by dividing $4.075 by the Parent Share Value and rounding to the nearest ten-thousandth of a share.

Each Common Unit converted into the right to receive the Common Unit Consideration pursuant to this Section 2.1(a) shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each holder of a Common Unit immediately prior to the Effective Time (whether certificated or non-certificated and represented in book-entry form) shall thereafter cease to be a limited partner of the Company or have any rights with respect to such Common Units, except the right to receive the Common Unit Consideration.

(b) Conversion of Preferred Units. Subject to Section 2.1(e), each Preferred Unit issued and outstanding immediately prior to the Effective Time shall thereupon be converted automatically into and shall thereafter represent the right to receive the following consideration (the “Preferred Unit Consideration”) (i) $4.075 per Preferred Unit in cash without interest, and (ii) a fraction of a validly issued, fully paid and nonassessable Parent Share equal to the quotient determined by dividing $4.075 by the Parent Share Value and rounding to the nearest ten-thousandth of a share. Each Preferred Unit converted into the right to receive the Preferred Unit Consideration pursuant to this Section 2.1(b) shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each holder of a Preferred Unit immediately prior to the Effective Time (whether certificated or non-certificated and represented in book-entry form) shall thereafter cease to be a limited partner of the Company or have any rights with respect to such Preferred Units, except the right to receive the Preferred Unit Consideration.

(c) General Partner Units; Incentive Distribution Rights. Subject to Section 2.1(e), each General Partner Unit issued and outstanding immediately prior to the Effective Time shall thereupon be converted automatically into and shall thereafter represent the right to receive $8.15 in cash without interest per General Partner Unit (the “GP Unit Consideration”). The Incentive Distribution Rights issued and outstanding immediately prior to the Effective Time shall at the Effective Time be converted automatically into and shall thereafter represent the right to receive consideration of $18,000,000 in cash without interest (the “GP IDR Consideration,” and, together with the GP Unit Consideration, the “GP Consideration”). The General Partner Units and Incentive Distribution Rights converted into the right to receive the GP Consideration pursuant to this Section 2.1(c) shall cease to be outstanding and shall be canceled and retired and shall cease to exist. Immediately following the admission of Holding Sub as the general partner of the Company pursuant to Section 2.1(d), Company General Partner shall cease to be a general partner of the Company, IDR Holdings shall cease to be a limited partner of the Company and neither Company General Partner nor IDR Holdings will have any rights with respect to the General Partner Units or the Incentive Distribution Rights (whether such interests are certificated or non-certificated and represented in book-entry form), except the right to receive the GP Consideration and the obligations set forth in Section 6.11.

(d) Conversion of Merger Sub Limited Liability Company Interests; Admission of General Partner and Limited Partner. At the Effective Time, by virtue of the Merger and without any action on the part of Parent or any of its Subsidiaries (i) Holding Sub’s limited liability company interest in Merger Sub shall be converted into and become a 1% general partner interest in the Surviving Company and Holding Sub shall be admitted to the Surviving Company as the sole general partner, (ii) LP Sub’s limited liability company interest in Merger Sub shall be converted into and become a 99% limited partner interest in the Surviving Company, and LP Sub shall be admitted to the Surviving Company as the sole limited partner, and (iii) the Company shall continue without dissolution. Immediately after the Effective Time, such general partner interest and limited partner interest referred to in the preceding sentence will constitute the only

outstanding partnership interests in the Surviving Company. At the Effective Time, Holding Sub and LP Sub shall be automatically bound by the Surviving Company Partnership Agreement and the books and records of the Surviving Company shall be revised to reflect the admission of Holding Sub and LP Sub as the sole general partner and sole limited partner, respectively, of the Surviving Company and the withdrawal, immediately following such admissions, of (y) Company General Partner as general partner of the Company, and (z) all Limited Partners (other than LP Sub) as limited partners of the Company.

(e) Adjustments. If between the date of this Agreement and the Effective Time, the outstanding Units or capital stock of Parent, including securities convertible or exchangeable into or exercisable for Units or capital stock of Parent, shall be changed into a different number of units, shares or other securities by reason of any split (including reverse split), combination, merger, consolidation, reorganization, reclassification, recapitalization or other similar transaction, or any distribution payable in any equity interests in the Company or Parent shall be declared thereon with a record date within such period, the Merger Consideration, the exchange ratios and any other similarly dependent items described herein, as the case may be, shall be appropriately adjusted to provide the holders of interests of the Company converted into Merger Consideration pursuant to this Section 2.1 the same economic effect as contemplated by this Agreement prior to such event, and as so adjusted shall, from and after the date of such event, be the Merger Consideration, the applicable exchange ratio or other dependent item, as applicable, subject to further adjustment in accordance with this sentence; provided, however, that nothing herein shall be construed to permit the Company Entities to take any action with respect to their securities that is expressly prohibited by Section 5.1.

Section 2.2 Election Procedures.

(a) At the time of mailing of the Proxy Statement/Prospectus to holders of record of Common Units entitled to vote at the Unitholder Meeting (such date, the “Mailing Date”), an election form and other appropriate and customary transmittal materials (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates theretofore representing Common Units, or Book-Entry Common Units, shall pass, only upon proper delivery of such Certificates or Book-Entry Common Units, respectively, to the Exchange Agent, upon adherence to the procedures set forth in the letter of transmittal) in such form as Parent and the Company shall reasonably agree (the “Election Form”) shall be mailed to each holder of record of Common Units as of the record date for the Unitholder Meeting.

(b) Each Election Form shall permit the holder (or the beneficial owner through appropriate and customary documentation and instructions) to specify (i) the number of such holder’s Common Units with respect to which such holder makes a Cash Election, and (ii) the number of such holder’s Common Units with respect to which such holder elects to make a Mixed Election. Any Common Units with respect to which the Exchange Agent has not received an effective, properly completed Election Form on or before 5:00 p.m., New York time, on the Business Day that is three (3) Business Days prior to the Closing Date (which date shall be publicly announced by Parent as soon as reasonably practicable) (or such other time and date as the Company and Parent shall agree in writing) (the “Election Deadline”) shall be deemed to be “Non-Electing Common Units.” If the Closing Date is delayed to a subsequent date, the Election Deadline shall be similarly delayed to a subsequent date, and Parent shall promptly announce any such delay and, when determined, the rescheduled Election Deadline, if any.

(c) Parent shall make Election Forms available as may reasonably be requested from time to time by all Persons who become holders (or beneficial owners) of Common Units

between the record date for the Unitholder Meeting and the Election Deadline, and the Company shall provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein and as specified in any agreement with the Exchange Agent.

(d) Any election made pursuant to this Section 2.2 shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form prior to the Election Deadline. An Election Form shall be deemed properly completed only (i) if accompanied by one or more Certificates representing Common Units duly endorsed in blank or otherwise in form acceptable for transfer on the books of the Company (or by an appropriate guarantee of delivery of such Certificates as set forth in such Election Form from a firm that is an “eligible guarantor institution” (as defined in Rule 17Ad-15 under the Exchange Act), and/or (ii) upon receipt of an “agent’s message” by the Exchange Agent or such other evidence of transfer of Book-Entry Common Units to the Exchange Agent as the Exchange Agent may reasonably request, collectively representing all Common Units covered by such Election Form, together with duly executed transmittal materials included with the Election Form. Any Election Form may be revoked or changed by the Person submitting such Election Form, by written notice received by the Exchange Agent prior to the Election Deadline. In the event an Election Form is revoked prior to the Election Deadline, the Common Units represented by such Election Form shall become Non-Electing Common Units and Parent shall cause the Certificates representing such Common Units to be promptly returned without charge to the Person submitting the Election Form upon such revocation or written request to that effect from the holder who submitted the Election Form; provided, however, that a subsequent election may be made with respect to any or all of such Common Units pursuant to this Section 2.2. In addition, all Cash Elections and Mixed Elections shall automatically be revoked and all Certificates representing Common Units shall be promptly returned without charge if this Agreement is terminated in accordance with Article 8 of this Agreement.

(e) Subject to the terms of this Agreement and of the Election Form, the Exchange Agent, in consultation with both Parent and the Company, shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the Election Forms, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. None of Parent or the Company or the Exchange Agent shall be under any obligation to notify any Person of any defect in an Election Form.

Section 2.3 No Fractional Shares. No certificates or scrip representing fractional Parent Shares or book-entry credit of the same shall be issued upon the surrender for exchange of Certificates (or effective affidavits of loss in lieu thereof) or Book-Entry Interests, no dividends or other distributions of Parent shall relate to such fractional share interests, including any fractional share interests resulting pursuant to Section 2.1(a), (b) or (c), and such fractional share interests will not entitle the owner thereof to vote or to any rights of a stockholder of Parent. In lieu of such fractional share interests, Parent shall pay to each holder of a Certificate (upon surrender thereof as provided in this Article 2) or Book-Entry Interest an amount in cash equal to the product obtained by multiplying (y) the fractional share interest to which such holder would otherwise be entitled (after taking into account all Company Equity Interests formerly represented by Certificates or Book-Entry Interests), by (z) the Parent Share Value.

Section 2.4 Exchange of Certificates and Book Entry Interests.

(a) Prior to the Mailing Date, Parent shall appoint a commercial bank or trust company reasonably acceptable to the Company to act as agent (the “Exchange Agent”) for the purpose of exchanging Certificates and Book-Entry Interests for the Merger Consideration.

Parent shall pay all costs, fees, and expenses incurred in connection with the retention and engagement of the Exchange Agent. In connection with the foregoing, Parent and Merger Sub shall enter into an exchange agent and nominee agreement with the Exchange Agent, in a form reasonably acceptable to the Company, setting forth the procedures to be used in accomplishing the deliveries and other actions contemplated by this Section 2.4 and by Section 2.2 and Section 2.3.

(b) As soon as reasonably practicable after the Effective Time, Parent shall cause to be mailed to each record holder, as of the Effective Time, of Certificates or Book-Entry Interests representing Company Equity Interests (other than any holder which has previously and properly surrendered all of its Certificate(s) or Book-Entry Interests to the Exchange Agent in accordance with Section 2.2), a form of letter of transmittal (which shall be in customary form and 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 to the Exchange Agent or, in the case of Book-Entry Interests, upon adherence to the procedures set forth in the letter of transmittal) and instructions for use in effecting the surrender of the Certificates or, in the case of Book-Entry Interests, the surrender of such interests in exchange for the Merger Consideration.

(c) Immediately prior to the Effective Time, Parent shall (1) issue and deposit or cause to be deposited with the Exchange Agent to be held in trust for the holders of Company Equity Interests, evidence of shares in book-entry form, representing Parent Shares issuable pursuant to Section 2.1 in exchange for (x) outstanding Common Units for which a Mixed Election (to the extent such consideration is payable in Parent Shares) has been made, (y) outstanding Preferred Units (to the extent such consideration is payable in Parent Shares), and (z) outstanding General Partner Units (to the extent such consideration is payable in Parent Shares) and an amount of cash representing the aggregate cash consideration payable pursuant to Section 2.1, and (2) deposit with the Exchange Agent, from time to time as needed, cash in amounts that are sufficient to pay cash in lieu of fractional shares pursuant to Section 2.3, and to make any dividends or other distributions pursuant to Section 2.4(g), in each case, to be paid in respect of the Certificates and the Book-Entry Interests by holders thereof who have properly delivered to the Exchange Agent their Common Units, Preferred Units, General Partner Units, or Incentive Distribution Rights. Any cash and Parent Shares deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.” The Exchange Agent shall, subject to the terms of the exchange agent and nominee agreement entered into with Parent, deliver the Merger Consideration contemplated to be issued pursuant to Section 2.1, Section 2.2, and Section 2.3 out of the Exchange Fund. Until used for that purpose, the cash portion of the Exchange Fund shall be invested by the Exchange Agent in short-term obligations of or guaranteed by the United States of America or short-term obligations of an agency of the United States of America which are backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Services Inc. or Standard & Poor’s Corporation, or in deposit accounts, short-term certificates of deposit or banker’s acceptances of, or repurchase or reverse repurchase agreements with commercial banks which have capital surplus and undivided profits aggregating more than $10 billion (based on the most recent financial statements of the banks which are then publicly available at the SEC or otherwise); provided, however, that no such investment or losses thereon shall affect the Merger Consideration payable to former holders of Company Equity Interests entitled to receive such consideration or cash in lieu of fractional interests, and Parent shall promptly provide, or shall cause the Surviving Company to promptly provide, additional cash funds to the Exchange Agent for the benefit of the former holders of Company Equity Interests in the amount of any such losses. The Exchange Fund shall not be used for any purpose other than the foregoing.

(d) Each holder of Company Equity Interests that have been converted into a right to receive the Merger Consideration, upon completion of the calculations required by Section 2.1 and surrender of a Certificate or Book-Entry Interests to the Exchange Agent together with the letter of transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, will be entitled to receive in exchange therefor (A) one or more Parent Shares which shall be in uncertificated book-entry form and which shall represent, in the aggregate, the whole number of Parent Shares that such holder has the right to receive pursuant to Section 2.1 (after taking into account all Company Equity Interests then held by such holder) and/or (B) a check in the amount equal to any cash that such holder has the right to receive pursuant to this Article 2, consisting of the cash consideration pursuant to Section 2.1, cash in lieu of any fractional shares pursuant to Section 2.3, and any dividends and other distributions pursuant to Section 2.4(g), in each case, less any required withholding Taxes. The Merger Consideration shall be paid as promptly as reasonably practicable after receipt by the Exchange Agent of the Certificate or Book-Entry Interests and letter of transmittal in accordance with the foregoing. No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional shares in accordance with Article 2 hereof or on any unpaid dividends and distributions payable to holders of Certificates or Book-Entry Interests. Until so surrendered, each such Certificate and Book-Entry Interest shall, from and after the Effective Time, represent for all purposes only the right to receive the Merger Consideration, the issuance or payment of which (including any cash in lieu of fractional shares) shall be deemed to be the satisfaction in full of all rights pertaining to Company Equity Interests converted in the Merger.

(e) If any cash payment is to be made to a Person other than the Person in whose name the applicable surrendered Certificate or Book-Entry Interest is registered, it shall be a condition of such payment that the Person requesting such payment shall pay any transfer or other similar Taxes required by reason of the making of such cash payment to a Person other than the registered holder of the surrendered Certificate or Book-Entry Interest or shall establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable. If any portion of the Merger Consideration is to be registered in the name of a Person other than the Person in whose name the applicable surrendered Certificate or Book-Entry Interest is registered, it shall be a condition to the registration thereof that the surrendered Certificate or Book-Entry Interest shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other similar Taxes required as a result of such registration in the name of a Person other than the registered holder of such Certificate or Book-Entry Interest or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(f) Subject to Section 2.1(d), at the Effective Time, the equity transfer books of the Company shall be closed and there shall be no further registration of transfers of Company Equity Interests thereafter. If, after the Effective Time, any Certificates or Book-Entry Interests representing such Company Equity Interests are presented for transfer to the Exchange Agent, each such interest shall be cancelled and exchanged for the Merger Consideration provided for in this Article 2 in accordance with the terms hereof. In the event of a transfer of ownership of any Company Equity Interests prior to the Effective Time that has not been registered in the transfer records of the Company, the Merger Consideration payable in respect of such Company Equity Interests shall be paid to the transferee of such interest if the Certificate or Book-Entry Interest that previously represented such Company Equity Interest is presented to the Exchange Agent accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable transfer Taxes have been paid. From and after the Effective Time, the holders of Certificates and Book-Entry Interests representing Company Equity Interests outstanding

immediately prior to the Effective Time shall cease to have any rights with respect to such Company Equity Interests except as otherwise provided in this Agreement or by applicable Law.

(g) No dividends or other distributions with respect to Parent Shares issued in the Merger shall be paid to the holder of any unsurrendered Certificates or Book-Entry Interests until such Certificates or Book-Entry Interests are surrendered as provided in this Article 2. Following such surrender, subject to the effect of escheat, Tax or other applicable Law, there shall be paid, without interest, to the record holder of the Parent Shares, if any, issued in exchange therefor (i) at the time of such surrender, all dividends and other distributions payable in respect of any such Parent Shares with a record date after the Effective Time and a payment date on or prior to the date of such surrender and not previously paid, and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to such Parent Shares with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of dividends or other distributions in respect of Parent Shares, all Parent Shares to be issued pursuant to the Merger shall be entitled to dividends or other distributions pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

Section 2.5 Termination of Fund. Any portion of the Exchange Fund that remains unclaimed by holders of Company Equity Interests for twelve (12) months after the Effective Time shall be paid to the Surviving Company or, if so directed by the Surviving Company, to Parent. Any holders of Company Equity Interests who have not theretofore complied with this Article 2 shall thereafter look only to Parent and the Surviving Company for payment of the Merger Consideration deliverable in respect of each Company Equity Interest formerly held by such holder as determined pursuant to this Agreement without any interest thereon, and Parent and the Surviving Company shall be responsible with respect to such payment. Notwithstanding the foregoing, none of the Company, Parent, the Exchange Agent or any other Person shall be liable to any former holder of Company Equity Interests for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar Laws. Any portion of the Exchange Fund that remains unclaimed by holders of Company Equity Interests prior to the date on which such portion of the Exchange Fund would otherwise escheat to or become the property of any Governmental Entity shall, to the extent permitted by applicable Law and immediately prior to such date, become the property of the Surviving Company, free and clear of all claims or interest of any person previously entitled thereto.

Notwithstanding the foregoing, the Company Board (including the Conflicts Committee) may, at any time prior to obtaining the Company Unitholder Approvals and subject to compliance with Section 5.2(d), effect a Change in Recommendation in response to (A) a bona fide written Acquisition Proposal made after the date of this Agreement that the Company Board (or the Conflicts Committee, as applicable) reasonably determines in good faith (after consultation with its outside legal and financial advisors) constitutes a Superior Proposal and that was not solicited in violation of this Section 5.2 or (B) an Intervening Event if, in the case of any such Change in Recommendation, the Company Board (or the Conflicts Committee, as applicable) shall have determined in good faith, after consultation with outside counsel, that, in light of such Superior Proposal or Intervening Event, the failure to take such action constitutes or is reasonably likely to constitute a violation of its fiduciary duties to the Unitholders under applicable Law. Any Change in Recommendation shall not change the approval of this Agreement or any other

approval of the Company General Partner, the Company Board or the Conflicts Committee in any respect, including any change that would have the effect of causing any Takeover Statute or other similar statute to be applicable to the transactions contemplated hereby (including the Merger).

(d) Notwithstanding anything herein to the contrary, the Company Board (including the Conflicts Committee) shall not be entitled to effect a Change in Recommendation or terminate this Agreement pursuant to Section 8.1(j) unless:

(i) the Company has provided to Parent three (3) Business Days’ prior written notice (a “Notice”) advising Parent that the Company Board is prepared to take such action and specifying the reasons therefor (it being understood and agreed that any amendment to the financial terms or any material amendment to any other material term of any such Acquisition Proposal or any change in any such Intervening Event shall require a new Notice and a new three (3) Business Day period);

(ii) (A) with respect to an Acquisition Proposal that the Company Board has determined constitutes a Superior Proposal, (x) the Company has provided or made available to Parent all material information concerning its business, properties or assets delivered or made available to the Third Party making such Acquisition Proposal that the Company Board has determined constitutes a Superior Proposal and (y) the Notice includes a description of the material terms and conditions of such Acquisition Proposal and the proposed financing for such Acquisition Proposal (including copies of any written requests, proposals, offers, and proposed agreements) and the identity of the Third Party making the proposal or (B) with respect to an Intervening Event, the Company has provided Parent with written information describing such Intervening Event in reasonable detail; and

(iii) during such three (3) Business Day period, if requested by Parent, the Company (A) provides an opportunity for Parent to propose amendments to this Agreement in such a manner that the Acquisition Proposal that was determined to constitute a Superior Proposal no longer is a Superior Proposal or the event or circumstance that was determined to constitute an Intervening Event no longer is an Intervening Event and (B) negotiates and uses its reasonable best efforts to cause the Company Representatives to negotiate in good faith with Parent and its representatives regarding any such amendments to this Agreement; and

(iv) at 11:59 p.m., Houston, Texas time, at the end of such three (3) Business Day period, (A) with respect to an Acquisition Proposal that the Company Board has determined constitutes a Superior Proposal, such Acquisition Proposal has not been withdrawn and the Company Board has reasonably concluded in good faith (after consultation with its outside legal and financial advisors) that such Acquisition Proposal continues to constitute a Superior Proposal and (B) with respect to an event or circumstance that the Company Board has determined constitutes an Intervening Event, the Company Board has reasonably concluded that such event or circumstance continues to constitute an Intervening Event; provided, however, that in making the determinations contemplated by this clause (iv), the Company Board shall take into account any changes to the financial and other terms of this Agreement proposed by Parent following the Notice and as a result of the negotiations between Parent and the Company pursuant to this Section 5.2(d).

(e) Nothing contained in this Section 5.2 or any other provision of this Agreement shall prohibit the Company or the Company Board (either by the full Company Board or through a committee thereof, including the Conflicts Committee) from (A) taking and disclosing to Unitholders a position with respect to a tender or exchange offer by a Third Party contemplated by Rule 14e-2(a) or making a statement required under Rule 14d-9 under the Exchange Act or (B) making any disclosure to the Unitholders if either the full Company Board or a committee thereof, including the Conflicts Committee, has determined, in good faith, after consultation with outside counsel, that the failure to make such disclosure constitutes or would be reasonably likely to constitute a violation of its fiduciary duties to the Unitholders under applicable Law, provided, however, that (i) compliance with such rules shall in no way limit Parent’s right to terminate this Agreement pursuant to Section 8.1 hereof and receive payment of any Termination Fee and any other amounts payable to it pursuant to Section 8.3, and (ii) in no event shall the Company or the Company Board (or any committee thereof, including the Conflicts Committee) (A) effect, or agree or resolve to effect, a Change in Recommendation except as permitted by Section 5.2(c), or (B) withdraw or modify, in a manner adverse to Parent or Merger Sub, the General Partner Approval.

(f) The Company will promptly (and in any event within 24 hours after receipt) advise Parent in writing of the receipt by the Company of any Acquisition Proposal after the date of this Agreement, the material terms and conditions of any such Acquisition Proposal and the proposed financing for such Acquisition Proposal (including copies of any written requests, proposals, offers, and proposed agreements) and the identity of the Person making any such Acquisition Proposal. The Company will keep Parent promptly and reasonably informed in all material respects of the status and details (including any material change to the terms thereof) of any such Acquisition Proposal and the proposed financing for such Acquisition Proposal.

(g) As used in this Agreement, the following terms have the meanings set forth below:

“Acquisition Proposal” means any proposal or offer (including any proposal or offer from or to the Unitholders), whether in writing or otherwise, from a Third Party related to a merger, reorganization, unit exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving the Company, Company General Partner, Management General Partner or any Significant Company Subsidiary, or any purchase, sale or other transfer of 20% or more of the consolidated assets (including stock or equity interests of any Company Subsidiary) of the Company, Company General Partner, Management General Partner and the Company Subsidiaries, or any purchase or sale of, or tender or exchange offer for, or other transfer of, their respective equity securities that, if consummated, would result in any Person (or the equity holders of such Person) beneficially owning securities representing 20% or more of the total voting power of the Company, Company General Partner, or Management General Partner, or any portion of the general partner interest in the Company (or 20% or more of the surviving parent entity in such transaction) other than the Merger, whether pursuant to a single transaction or a series of related transactions.

“Intervening Event” means an event or circumstance that was not known to the Company Board (or the Conflicts Committee, as applicable) at the date hereof (or if known, the material consequences of which were not known to or understood by the Company Board (or the Conflicts Committee, as applicable) as of the date hereof), which event or circumstance, or any material consequences thereof, becomes known to or understood by the Company Board (or the Conflicts Committee, as applicable) prior to the Company Unitholder Approvals and which causes the Company Board (or the Conflicts Committee, as applicable) to conclude in good faith, after

consultation with its financial advisor and outside counsel, that a failure to make a Change in Recommendation constitutes or would be reasonably likely to constitute a violation of its fiduciary duties to the Unitholders under applicable Law; provided, however, that in no event shall any of the following constitute an Intervening Event: (i) the receipt, existence or terms of an Acquisition Proposal or any matter relating thereto or consequence thereof, or (ii) any change in, or event or condition generally affecting, the industry in which the Company and its Subsidiaries operate.

“Significant Company Subsidiary” means any Company Subsidiary that would be a “significant subsidiary” as defined in Rule 12b-2 promulgated under the Exchange Act.

“Superior Proposal” means any bona fide, written proposal by a Third Party that, if consummated, would result in such Third Party (or its equityholders) owning, directly or indirectly, all of the Common Units, Preferred Units and General Partner Units then outstanding (or of the shares, interests or units of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or all or substantially all of the consolidated assets of the Company and its Subsidiaries, (i) which the Company Board and the Conflicts Committee both determine in good faith (after consultation with its outside legal and financial advisors) to be more favorable to the Company and the Unitholders from a financial point of view than the transactions contemplated by this Agreement (after giving effect to any changes to the financial terms of this Agreement proposed by Parent in response to such offer or otherwise) and (ii) which is not subject to a financing condition, and which, in the good faith judgment of the Company Board and the Conflicts Committee, is otherwise reasonably likely to be consummated on the terms set forth in the proposal, taking into consideration (with respect to both subsections (i) and (ii) hereof) all financial, regulatory, legal, timing and other aspects of such proposal (including any break-up fee and conditions to consummation).

“Third Party” means any Person or group other than Parent, Merger Sub or any Affiliate thereof.

(h) Unless this Agreement is terminated pursuant to, and in accordance with, Section 8.1 of this Agreement, the obligation of the Company pursuant to Section 6.1(c) to call, give notice of and hold the Unitholder Meeting and to hold a vote of the Unitholders on the approval of this Agreement and the approval of the Merger at the Unitholder Meeting shall not be limited or otherwise affected by any Change in Recommendation or the commencement, disclosure, announcement or submission to any Company Entity of any Acquisition Proposal (whether or not a Superior Proposal).

(i) The Company acknowledges that the agreements contained in this Section 5.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent would not have entered into this Agreement. Accordingly, if there shall have been any permanent injunction, other Order issued by any Court of competent jurisdiction or other legal restraint or prohibition, that (A) would require or permit the Company, any Company Party or any Company Representative to act or fail to act in a manner that would, in the absence of such order, injunction or other Order, legal restraint or prohibition, constitute a material violation of Section 5.2(a)(i) or (B) limits the rights of Parent in any material respect under this Section 5.2, Parent shall have the right to terminate this Agreement pursuant to Section 8.1(i) hereof.

Section 5.3 Control of Other Party’s Business. Nothing contained in this Agreement shall give the Company Entities, directly or indirectly, the right to control or direct Parent’s operations or give

Parent, directly or indirectly, the right to control or direct the Company Entities’ operations prior to the Effective Time. Prior to the Effective Time, each of Parent, on one hand, and the Company Entities, on the other hand, shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over their respective operations.

If at any time prior to the Effective Time any event occurs or information relating to the Company or Parent, or any of their respective Affiliates, directors or officers, should be discovered by the Company or Parent that should be set forth in an amendment or supplement to either the Form S-4 or the Proxy Statement/Prospectus, so that either such document 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 that discovers such information shall promptly notify the other party hereto and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by applicable Law, disseminated to the Unitholders.

any direction, determination, requirement, injunction, order, condition or limitation that prevents or would prevent, or that makes illegal, the timely consummation of the Merger and the other transactions contemplated by this Agreement; provided, however, and notwithstanding anything in this Agreement to the contrary, Parent and its Subsidiaries shall have no obligation to (i) seek appellate review by any court or appellate review by any administrative agency (including but not limited to plenary hearing at the FTC) of any Order, decree, initial decision, or ruling pertaining to the Merger or other transactions contemplated by this Agreement, or (ii) sell, hold separate or otherwise dispose of any business or assets or conduct their business in a specified manner prior to or following the Closing Date in connection with the receipt of any necessary governmental approvals, clearances or agreements not to contest the transactions contemplated under this Agreement.

No delivery of any notice pursuant to this Section 6.7 will cure any breach of any representation or warranty of such party contained in this Agreement or otherwise limit or affect

the remedies available hereunder to the party receiving such notice. Without limiting the foregoing, the Company Parties and Parent shall promptly advise each other of any change or event having a Company Material Adverse Effect or Parent Material Adverse Effect, as applicable.

(c) Tax Treatment. The parties hereto intend that the transactions contemplated by this Agreement, including the Merger, be treated for U.S. federal income tax purposes as (i) a sale by the holders of the Company Equity Interests and (ii) a purchase by Parent of the assets held by (and subject to the liabilities of) Company (and the assets held by (and subject to the liabilities of) each Company Subsidiary that is disregarded as an entity separate from Company for U.S. federal income tax purposes) at the time of the Closing, pursuant to Situation 2 of Revenue Ruling 99-6, 1999-1 C.B. 432.

(a) Without limiting any rights that any Person may have under any employment agreement or Company Benefit Plan, after the Effective Time, Parent and the Surviving Company shall, jointly and severally, indemnify, defend and hold harmless the present and former officers and directors of the Company Entities in such capacities (“Indemnified Parties”) to the fullest extent permitted by Law, in each case against any losses, damages, fines, penalties, expenses (including attorneys’ fees and expenses) or liabilities resulting from any claim, liability, loss, damage, cost or expense (each a “Claim”), asserted against, or incurred by, an Indemnified Party that is based on the fact that such Indemnified Party is or was a director, officer, employee, fiduciary or agent of the Company or any of its Subsidiaries and arising out of actions or omissions or alleged actions or omissions in their capacity as a director, officer, employee, fiduciary or agent of any of the Company Entities occurring at or prior to the Effective Time (including in connection with this Agreement and the transactions contemplated hereby). Parent and the Surviving Company shall, jointly and severally, pay expenses in advance of the final disposition of any pending or threatened Proceeding to each Indemnified Party to the fullest extent permitted under applicable Law. Each Indemnified Party will be entitled to receive such advances from Parent or the Surviving Entity within ten (10) Business Days of receipt by Parent or the Surviving Entity from the Indemnified Party of a request therefor; provided that any Person to whom expense are advanced provides an undertaking, if and only to the extent required by law, to repay such advances if it is ultimately determined that such Person is not entitled to indemnification. Neither Parent nor the Surviving Company shall settle, compromise or consent to the entry of any judgment in any Proceeding (and in which indemnification could be sought by such Indemnified Party hereunder), unless such settlement, compromise or consent includes any unconditional release of such Indemnified Party from all liability arising out of such Claim or such Indemnified Party otherwise consents. Parent and the Surviving Company shall, and shall cause their Subsidiaries to, cooperate in the defense of any such matter. Parent and the Surviving Company agree that all rights to exculpation, advancement of expenses and indemnification for acts or omissions occurring prior to the Effective Time now existing in favor of current and former officers and directors of any of the Company Entities as provided in any Contract listed in Section 6.13 of the Company Disclosure Letter, any Company Benefit Plan, or any Company Entity Charter Document, each as in effect as of the date hereof, shall survive the Merger and shall continue in full force and effect in accordance with their terms and without regard to any subsequent amendment thereof.

(b) Prior to Closing, the Company shall purchase (after obtaining the written approval of Parent, which approval shall not be unreasonably withheld, delayed or conditioned), and after the Effective Time, the Surviving Company shall maintain, or if the Company has not already done so, purchase tail directors’ and officers’ liability insurance coverage, at no expense

to the beneficiaries, with a claims period of six (6) years from the Effective Time, with respect to the directors and officers of the Company Entities who are currently covered by existing director’ and officers’ liability insurance with respect to claims arising from facts or events that occurred before the Effective Time, from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier, in an amount and scope and on terms and conditions no less favorable to such directors and officers than those in effect on the date of this Agreement; provided, however, that the annual premium for such insurance shall not exceed 300% of the per annum rate of premium currently paid by the Company Entities for such insurance on the date of this Agreement. In the event that the annual premium for such insurance exceeds such maximum amount, the Parent shall purchase as much coverage per policy year as reasonably obtainable for such maximum amount.

(c) This covenant is intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and legal representatives. The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to law, contract or otherwise.

(d) In the event that the Surviving Company or Parent, or any of their respective successors or assigns, (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Company or Parent, as the case may be, shall succeed to the obligations set forth in this Section 6.13.

Section 6.14 Employee Matters.

(a) Parent shall or shall cause the Company to maintain for shoreside employees who continue in the employ of Parent, the Company or any of their Subsidiaries following the Closing Date (“Continuing Employees”), for the one-year period following the Closing Date or such shorter period during which a Continuing Employee remains an employee, the base salary or wages and annual incentive bonus opportunities and other benefit plans and arrangements provided by the Company on the date of this Agreement (“Compensation Arrangements”).

(b) Prior to the Closing, the Company shall enter into, adopt or amend such Company Benefit Plans or other agreements to provide that if the employment of a Continuing Employee is terminated during the one (1) year period following the Effective Time, then Parent shall or shall cause the Company to provide such employee with severance equal to the greater of (i) the severance amount (and according to the terms) set forth in Section 6.14(b) of the Company Disclosure Letter, or (ii) the severance applicable to the employee under any Contract as in effect on the date hereof.

(c) From and after the Closing, Parent shall recognize each Continuing Employee’s service with the Company or any of its Subsidiaries, and with any predecessor employer, in each case, to the same extent recognized by the Company or any of its Subsidiaries on the date of this Agreement for purposes of eligibility to participate and vesting but not benefit accrual under any employee benefit plans or arrangements (including under any applicable 401(k), savings, medical, dental, life insurance, vacation, severance or separation pay plans) provided, sponsored, maintained or contributed to by Parent or any of its Subsidiaries for such Continuing Employees, except to the extent such credit would result in the duplication of benefits or compensation for the same period of service.

(d) Parent shall (i) use commercially reasonable efforts to waive, in the plan year in which the Closing Date occurs, for each Continuing Employee and his or her dependents any waiting period provision, payment requirement to avoid a waiting period, actively-at-work requirement and any other restriction that would prevent immediate or full participation under the welfare plans or pre-existing condition limitations of health benefit plans of Parent or any of its Subsidiaries applicable to such Continuing Employee to the extent such waiting period, pre-existing condition limitation, actively-at-work requirement or other restriction would not have been applicable to such Continuing Employee under the terms of the welfare benefit plans of the Company and its Subsidiaries on the date of this Agreement and (ii) use commercially reasonable efforts to, in the plan year in which the Closing Date occurs, give full credit under the health benefit plans of Parent and its Subsidiaries applicable to each Continuing Employee and his or her dependents for all co-payments and deductibles satisfied prior to the Closing in the same plan year in which the Closing occurs, and for any lifetime maximums, as if there had been a single continuous employer.

(e) This Section 6.14 shall not limit the obligation of Parent to maintain any compensation arrangement or benefit plan pursuant to an existing Contract set forth on the Company Disclosure Schedule. No provision of this Agreement shall be construed as a guarantee of continued employment of any Continuing Employee and this Agreement shall not be construed so as to prohibit Parent or any of its Subsidiaries from having the right to terminate the employment of any Continuing Employee or any other employee at any time and for any or no reason; provided that any such termination is effected in accordance with applicable Law.

(f) This Agreement is not intended by the parties to (i) constitute an amendment to any Company Benefit Plan or (ii) obligate Parent, the Company or its Subsidiaries, or any of their respective affiliates (including the Company) to maintain any particular compensation or benefit plan, program, policy or arrangement. Nothing contained in this Section 6.14 or any other provision of this Agreement shall be construed to create any third-party beneficiary right in any employee or other Person.

Section 6.15 Section 16 Matters. Prior to the Closing date, Parent, the Company and the Management General Partner and their respective boards of directors, shall use their reasonable best efforts to take all actions to cause any dispositions of Common Units (including derivative securities with respect to Common Units), Preferred Units, General Partner Units and the Incentive Distribution Rights, or acquisitions of Parent Shares (including derivative securities with respect to Parent Shares) resulting from the transactions contemplated hereby by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act to be exempt from Section 16(b) of the Exchange Act under Rule 16b-3 promulgated under the Exchange Act in accordance with the terms and conditions set forth in that certain No-Action Letter, dated January 12, 1999, issued by the SEC to Skadden, Arps, Slate, Xxxxxxx & Xxxx LLP.

The table of contents and headings contained in this Agreement are for reference purposes only and do not affect in any way the meaning or interpretation of this Agreement. As used in this Agreement, (a) the words “include,” “includes” or “including” shall be deemed to be followed by the words “without limitation,” (b) the word “or” shall not be exclusive, (c) the words “hereof,” “herein,” “hereunder,” “hereto” and words of similar import refer to this Agreement as a whole (including any Exhibits and Schedules hereto) and not to any particular provision of this Agreement, (d) all references to any period of days shall be to the relevant number of calendar days unless otherwise specified, (e) all references to dollars or $ shall be references to United States dollars, and (f) all accounting terms shall have their respective meanings under GAAP. All terms defined in this Agreement will have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver or consent and (in the case of statutes) by succession of comparable successor statutes (provided, however, that, in the case of Contracts that are the subject of representations and warranties set forth herein, copies of all amendments, modifications, waivers, consents or supplements have been provided on or prior to the date of this Agreement to the party to whom such

representations and warranties are being made). The parties hereto have participated jointly in the negotiating and drafting of this Agreement and, in the event an ambiguity or question of intent arises, this Agreement shall be construed as jointly drafted by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

Section 9.13 Counterparts; Effectiveness. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by all of the other parties hereto. Until and unless each party has received a counterpart hereof signed by each other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication). Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in PDF form, or by any other electronic means designed to preserve the original graphic and pictorial appearance of a document, will be deemed to have the same effect as physical delivery of the paper document bearing the original signatures.

Section 9.14 Disclosure Generally. A matter set forth in one item of either the Company Disclosure Letter or the Parent Disclosure Letter need not be set forth in any other item in the Company Disclosure Letter or the Parent Disclosure Letter so long as its relevance to the other sections or subsections therein or in this Agreement is reasonably apparent on the face of the matter disclosed. The fact that any item of information is disclosed in either the Company Disclosure Letter or the Parent Disclosure Letter shall not be construed to (a) mean that such information is required to be disclosed by this Agreement; (b) represent a determination that (i) such item is material or establishes a standard of materiality, (ii) such item did not arise in the ordinary course of business or (iii) the Merger requires the consent of third parties; or (c) constitute, or be deemed to be, an admission to any Person concerning such item. Such information and the dollar thresholds set forth herein shall not be used as a basis for interpreting the terms “material,” “Parent Material Adverse Effect” or “Company Material Adverse Effect” or other similar terms in this Agreement.

IN WITNESS WHEREOF, each of the parties hereto has caused this Agreement to be executed as of the date first written above by their respective officers thereunto duly authorized.
