ARTICLE II.

EFFECT ON UNITS

Section 2.1 Effect of Merger. At the Effective Time, by virtue of the Merger and without any action on the part of MLP GP, MLP, Parent GP, Parent or the holder of any securities of MLP:

(a) (i) Conversion of Common Units. Subject to Section 2.1(c), Section 2.2(h) and Section 2.4, each Common Unit issued and outstanding or deemed issued and outstanding in accordance with Section 2.3 as of immediately prior to the Effective Time shall be converted into the right to receive (x) $0.32 in cash (the “Cash Consideration”) and (y) 0.4066 (the “Exchange Ratio”) Parent Units (the “Unit Consideration” and, together with the Cash Consideration, the “Merger Consideration”).

(ii) Conversion of MLP General Partner Interest. The MLP General Partner Interest outstanding immediately prior to the Effective Time shall be converted into the right to receive Parent GP Interests such that, immediately following consummation of

the GP Merger, and assuming exchange and conversion of all the Common Units, Class F Units and Series A Units pursuant to this Section 2.1 and the Unit Options pursuant to Section 2.3, the Parent Percentage Interest represented by the Parent GP Interests shall equal the sum of (x) the Parent Percentage Interest represented by the Parent GP Interests immediately prior to the Effective Time, as adjusted to give effect to the issuance of Parent Units to be issued in connection with the Merger pursuant to Section 2.1 and Section 2.3, and (y) the MLP GP Percentage Interest. In connection therewith, Parent GP shall receive a right to any capital account in MLP associated with the MLP General Partner Interest immediately prior to the Merger.

(iii) Conversion of Class F Units. Subject to Section 2.1(c), Section 2.2(h) and Section 2.4, the Class F Units issued and outstanding as of immediately prior to the Effective Time shall be deemed to have been converted into an equal number of Common Units and such Common Units shall be converted into the right to receive the Merger Consideration pursuant to Section 2.1(a)(i).

(iv) Conversion of Series A Units. Subject to Section 2.1(c), Section 2.2(h) and Section 2.4, each Series A Unit issued and outstanding as of immediately prior to the Effective Time shall be converted into the right to receive a Series A preferred unit representing a limited partner interest in Parent (a “Parent Preferred Unit”), a new class of units in Parent containing provisions substantially equivalent to the provisions set forth in Section 5.14 of the MLP Partnership Agreement without abridgement including, the same powers, preferences, rights to distributions, rights to accumulation and compounding upon failure to pay distributions, and relative participating, optional or other special rights and the qualifications, limitations or restrictions thereon, that the Series A Units have immediately prior to the Closing (the “Series A Unit Consideration”).

(b) Cancellation of MLP Incentive Distribution Rights. The MLP Incentive Distribution Rights outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be canceled and retired and shall cease to exist. In connection with such cancellation, Parent GP shall receive a right to any capital account in MLP associated with the MLP Incentive Distribution Rights immediately prior to the Merger.

(c) Cancellation of MLP-Owned Units. Any MLP Securities that are owned immediately prior to the Effective Time by MLP or any Subsidiary of MLP shall be automatically canceled and shall cease to exist and no consideration shall be delivered in exchange for such canceled MLP Securities.

(d) Partnership Interests of the Surviving Entity. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, the partnership interests in Parent that had been issued and are outstanding as of immediately prior to the Effective Time shall be unchanged and remain outstanding.

(e) Certificates. As of the Effective Time, all Common Units and Class F Units converted into the Merger Consideration and all Series A Units converted into the Series A Unit Consideration, as applicable, pursuant to this Article II shall no longer be outstanding and shall

automatically be canceled and shall cease to exist, and each holder of a certificate (or evidence of units in book-entry form (“Book-Entry Units”)) that immediately prior to the Effective Time represented any such Common Units, Class F Units or Series A Units (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration or Series A Unit Consideration, as applicable, any distributions to which such holder is entitled pursuant to Section 2.2(g) and cash in lieu of any fractional Parent Units to which such holder is entitled pursuant to Section 2.2(h), in each case to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with Section 2.2(c), without interest, and the right to be admitted as a Parent Limited Partner. Parent GP hereby consents to the admission (as a Parent Limited Partner) of each MLP Unitholder who is issued Parent Units or Parent Preferred Units in accordance with this Article II, upon the proper surrender of the Certificate representing Common Units, Class F Units or Series A Units, as applicable. Upon such surrender of the Certificate (or upon a waiver of the requirement to surrender a Certificate granted by Parent GP in its sole discretion) and the recording of the name of such Person as a limited partner of Parent on the books and records of Parent, such Person shall automatically and effective as of the Effective Time be admitted as a Parent Limited Partner and be bound by the Parent Partnership Agreement as such. By its surrender of a Certificate, or by its acceptance of Parent Units or Parent Preferred Units, as applicable, a MLP Unitholder confirms its agreement to be bound by all of the terms and conditions of the Parent Partnership Agreement.

Section 2.2 Exchange of Certificates.

(a) Exchange Agent. Prior to the Closing Date, Parent shall appoint an exchange agent reasonably acceptable to MLP (the “Exchange Agent”) for the purpose of exchanging Certificates and Book-Entry Units for the Merger Consideration and Series A Unit Consideration, as applicable. As soon as reasonably practicable after the Effective Time, but in no event more than three business days following the Effective Time, Parent will send, or will cause the Exchange Agent to send, to each holder of record of Common Units, Class F Units and Series A Units as of the Effective Time (and, to the extent commercially practicable, to make available for collection by hand, during customary business hours commencing immediately after the Effective Time, if so elected by such holder of record), whose Common Units, Class F Units and Series A Units, as applicable, were converted into the right to receive the Merger Consideration or Series A Unit Consideration, as applicable, a letter of transmittal (which shall specify that the delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates and Book-Entry Units (or effective affidavits of loss in lieu thereof) to the Exchange Agent) in such forms as MLP and Parent may reasonably agree, including, as applicable, instructions for use in effecting the surrender of Certificates and Book-Entry Units (or effective affidavits of loss in lieu thereof) to the Exchange Agent in exchange for the Merger Consideration or Series A Unit Consideration, as applicable, and cash in lieu of any fractional Parent Units payable pursuant to Section 2.2(h).

(b) Deposit. At or prior to the Closing, Parent shall cause to be deposited with the Exchange Agent, in trust for the benefit of the holders of Common Units, Class F Units, Series A Units and Unit Options, an amount of (x) Parent Units (which shall be in non-certificated book-entry form), (y) Parent Preferred Units (which shall be in non-certificated book-entry form) and (z) cash in U.S. dollars sufficient to be issued and paid pursuant to Section 2.1(a), Section 2.3(b)

and Section 2.3(c), payable upon due surrender of the Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) pursuant to the provisions of this Article II. Following the Effective Time, Parent agrees to make available to the Exchange Agent, from time to time as needed, cash in U.S. dollars sufficient to pay any distributions pursuant to Section 2.2(g), any Parent Units sufficient to pay any Merger Consideration and any Parent Preferred Units sufficient to pay any Series A Unit Consideration, in each case, that may be payable from time to time following the Effective Time. All cash and book-entry units representing Parent Units and Parent Preferred Units deposited with the Exchange Agent or representing unit proceeds obtained pursuant to Section 2.2(h) shall be referred to in this Agreement as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration and Series A Unit Consideration contemplated to be issued or paid pursuant to this Article II out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent; provided, that (i) no such investment or losses thereon shall affect the Merger Consideration payable to holders of Common Units, Class F Units, Series A Units or Unit Options entitled to receive such consideration or cash in lieu of fractional interests pursuant to Section 2.3(a) and Parent shall promptly cause to be provided additional funds to the Exchange Agent for the benefit of holders of Common Units, Class F Units, Series A Units or Unit Options entitled to receive such consideration in the amount of any such losses; and (ii) such investments shall be in short-term obligations of the United States of America with maturities of no more than 30 days.

(c) Exchange. Each holder of Common Units, Class F Units and Series A Units that have been converted into the right to receive the Merger Consideration or Series A Unit Consideration, as applicable, upon surrender to the Exchange Agent of a properly completed letter of transmittal, duly executed and completed in accordance with the instructions thereto, a Certificate (or effective affidavits of loss in lieu thereof), Book-Entry Unit or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) and such other documents as may reasonably be required by the Exchange Agent, will be entitled to receive in exchange therefor (i) in the case of a Common Unitholder or Class F Unitholder, (x) the number of Parent Units representing, in the aggregate, the whole number of Parent Units that such holder has the right to receive in accordance with the provisions of this Article II and/or (y) a check denominated in U.S. dollars in the amount of cash that such holder has the right to receive pursuant to this Article II, including the Cash Consideration, and (ii) in the case of a Series A Unitholder, the number of Parent Preferred Units representing, in the aggregate, the whole number of Parent Preferred Units that such holder has the right to receive in accordance with the provisions of this Article II. The Merger Consideration and Series A Unit Consideration shall be paid as promptly as practicable by mail after receipt by the Exchange Agent of the Certificate (or effective affidavits of loss in lieu thereof), Book-Entry Units or other evidence of Unit Options and letter of transmittal in accordance with the foregoing. No interest shall be paid or accrued on any Merger Consideration, Series A Unit Consideration, cash in lieu of fractional Parent Units or on any unpaid distributions payable to holders of Certificates. Until so surrendered, each such Certificate shall, after the Effective Time, represent for all purposes only the right to receive such Merger Consideration or Series A Unit Consideration, as applicable. The Merger Consideration and Series A Unit Consideration paid upon surrender of Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) shall be deemed to have been paid in full satisfaction of all rights pertaining to the Common Units, Class F Units, Series A

Units, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof), as the case may be, formerly represented by such Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof).

(d) Other Payees. 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 Unit, or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) 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, Book-Entry Unit or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. If any portion of the Merger Consideration or Series A Unit Consideration is to be registered in the name of a Person other than the Person in whose name the applicable surrendered Certificate, Book-Entry Unit or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) is registered, it shall be a condition to the registration thereof that the surrendered Certificate shall be properly endorsed or otherwise be in proper form for transfer and that the Person requesting such delivery of the Merger Consideration or Series A Unit Consideration, as applicable, 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, Book-Entry Unit or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) or establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) No Further Transfers. From and after the Effective Time, there shall be no further registration on the books of MLP of transfers of Common Units, Class F Units or Series A Units. From and after the Effective Time, the holders of Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) representing Common Units, Class F Units or Series A Units outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Common Units, Class F Units or Series A Units, as applicable, except as otherwise provided in this Agreement or by applicable Law. If, after the Effective Time, Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) are presented to the Exchange Agent or Parent, they shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth, in this Article II.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the Common Unitholders, Class F Unitholders, Series A Unitholders or holders of Unit Options 12 months after the Effective Time shall be returned to Parent, upon demand, and any such holder who has not exchanged such holder’s Common Units, Class F Units, Unit Options or Series A Units for the Merger Consideration or Series A Unit Consideration, as applicable, in accordance with this Section 2.2 prior to that time shall thereafter look only to Parent for delivery of the Merger Consideration or Series A Unit Consideration, as applicable, in respect of such holder’s Common Units, Class F Units, Unit Options or Series A Units. Notwithstanding the foregoing, Parent and MLP shall not be liable to any Common Unitholder, Class F Unitholder, Series A Unitholder or holders of Unit Options for any Merger Consideration or Series A Unit Consideration, as applicable, duly delivered to a public official pursuant to applicable abandoned property Laws. Any Merger Consideration or Series A Unit

Consideration remaining unclaimed by Common Unitholders, Class F Unitholders, Series A Unitholders or holders of Unit Options immediately prior to such time as such amounts would otherwise escheat to, or become property of, any Governmental Authority shall, to the extent permitted by applicable Law, become the property of Parent free and clear of any claims or interest of any Person previously entitled thereto.

(g) Distributions. No distributions with respect to Parent Units or Parent Preferred Units issued in the Merger shall be paid to the holder of any unsurrendered Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) until such Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) are surrendered as provided in this Section 2.2. 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 Units or Parent Preferred Units, if any, issued in exchange therefor (i) at the time of such surrender, all distributions payable in respect of any such Parent Units or Parent Preferred Units 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 distributions payable with respect to such Parent Units or Parent Preferred Units with a record date after the Effective Time but with a payment date subsequent to such surrender. For purposes of distributions in respect of Parent Units or Parent Preferred Units, all Parent Units or Parent Preferred Units to be issued pursuant to the Merger shall be entitled to distributions pursuant to the immediately preceding sentence as if issued and outstanding as of the Effective Time.

(h) No Fractional Units. No certificates or scrip representing fractional Parent Units or Parent Preferred Units shall be issued upon the surrender for exchange of Certificates, Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof). Notwithstanding any other provision of this Agreement, each holder of Common Units, Class F Units or Unit Options converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a Parent Unit (after taking into account all Certificates (or effective affidavits of loss in lieu thereof), Book-Entry Units or other evidence of Unit Options (or effective affidavits of loss in lieu thereof) delivered by such holder) shall be entitled to receive, from the Exchange Agent in accordance with the provisions of this Section 2.2(h), a cash payment, without interest, in lieu of such fractional units representing such holder’s proportionate interest, if any, in the proceeds from the sale by the Exchange Agent (reduced by reasonable and customary fees of the Exchange Agent attributable to such sale) (as so reduced, the “unit proceeds”) in one or more transactions of a number of Parent Units, such number equal to the excess of (i) the aggregate number of Parent Units to be delivered to the Exchange Agent by Parent pursuant to Section 2.2(b) over (ii) the aggregate number of whole Parent Units to be distributed to the holders of Certificates pursuant to Section 2.2(c) (such excess, the “Excess Units”). The parties acknowledge that payment of the cash unit proceeds in lieu of issuing certificates or scrip for fractional units was not separately bargained-for consideration but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience to Parent that would otherwise be caused by the issuance of fractional units. As soon as practicable after the Effective Time, the Exchange Agent, as agent for the holders of Common Units, Class F Units or Unit Options that would otherwise receive fractional Parent Units, shall sell the Excess Units at then-prevailing prices on the NYSE in the manner provided in this Section 2.2(h) and such sales shall be executed in round lots to the extent practicable. Until the unit proceeds of

such sale or sales have been distributed to the holders of such Common Units, Class F Units or Unit Options, or the Exchange Fund is terminated, the Exchange Agent shall hold such unit proceeds in trust for the benefit of the holders of such Common Units, Class F Units and Unit Options (the “Fractional Unit Proceeds”). The Exchange Agent shall determine the portion of the Fractional Unit Proceeds to which each holder of such Common Units, Class F Units or Unit Options shall be entitled, if any, by multiplying the amount of the aggregate unit proceeds comprising the Fractional Unit Proceeds by a fraction, the numerator of which is the amount of the fractional unit interest to which such holder of such Common Units, Class F Units or Unit Options would otherwise be entitled and the denominator of which is the aggregate amount of fractional unit interests to which all holders of such Common Units, Class F Units or Unit Options would otherwise be entitled.

(i) Lost, Stolen or Destroyed Certificates. If any Certificate 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, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration or Series A Unit Consideration to be paid in respect of the Common Units, Class F Units or Series A Units, as applicable, represented by such Certificate as contemplated by this Article II.

(j) Withholding Taxes. Parent and the Exchange Agent shall deduct and withhold from the consideration otherwise payable pursuant to this Agreement to a Common Unitholder, Class F Unitholder or Series A Unitholder such amounts as are required to be deducted and withheld with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations promulgated thereunder, or under any provision of applicable state, local or foreign Tax Law (and to the extent deduction and withholding is required, such deduction and withholding shall be taken in Parent Units). To the extent amounts are so withheld and paid over to the appropriate Tax authority, such withheld amounts shall be treated for the purposes of this Agreement as having been paid to the former holder of the Common Units, Class F Units, Series A Units and Unit Options, as applicable, in respect of whom such withholding was made. If withholding is taken in Parent Units, Parent and the Exchange Agent shall be treated as having sold such consideration for an amount of cash equal to the fair market value of such consideration at the time of such deemed sale and paid such cash proceeds to the appropriate Tax authority.

(k) Tax Characterization of Merger and Cash Received. MLP and Parent each acknowledges and agrees that for federal income Tax purposes the transactions consummated pursuant to this Agreement will be treated as an “assets-over” partnership merger transaction under Treasury Regulations Sections 1.708-1(c)(1) and 1.708-1(c)(3)(i), whereby MLP will be the terminating partnership and Parent will be the resulting partnership. As a result, the transactions consummated pursuant to this Agreement shall be treated for U.S. federal income Tax purposes as a contribution of all of the assets of MLP to Parent in exchange for the Merger Consideration, the Series A Unit Consideration, the cash received in lieu of fractional Parent Units and the assumption of liabilities. To the maximum extent possible, the Cash Consideration and any cash received in lieu of fractional Parent Units shall be treated as a reimbursement of preformation capital expenditures described in Treasury Regulation Section 1.707-4(d). To the

extent the Cash Consideration and any cash received in lieu of fractional Parent Units exceeds the amount that can be so treated, such excess cash will be treated as proceeds of a disguised sale transaction described in Section 707(a)(2)(B) of the Code (a “Disguised Sale”). Each of MLP and Parent agrees to prepare and file all U.S. federal income Tax Returns in accordance with the foregoing and shall not take any position inconsistent therewith on any such Tax Return, or in the course of any audit, litigation or other proceeding with respect to U.S. federal income Taxes, except as otherwise required by applicable Laws following a final determination by a court of competent jurisdiction or other final administrative decision by an applicable Governmental Authority.

Section 2.3 Treatment of Phantom Units, Unit Options, Cash Units and Equity Plans. As soon as reasonably practicable following the date of this Agreement, and in any event prior to the Effective Time, the MLP Managing GP Board (or, if appropriate, any committee administering any MLP Equity Plans) will adopt resolutions, and MLP will take all other actions as may be necessary or required in accordance with applicable Law and each MLP Equity Plan (including, the award agreements in respect of awards granted thereunder) to give effect to this Section 2.3 to provide that:

(a) Treatment of Phantom Units. Except as otherwise expressly provided in the terms of a particular award or as provided in Section 5.2(a)(viii)(E) of the MLP Disclosure Schedule, each award of Phantom Units that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, cease to relate to or represent a right to receive Common Units and shall be converted, at the Effective Time, into the right to receive (i) the Cash Consideration, (ii) an award of phantom units relating to Parent Units (a “Converted Parent Phantom Unit Award”) on the same terms and conditions as were applicable to the corresponding award of Phantom Units, except that the number of Parent Units covered by each such Converted Parent Phantom Unit Award shall be equal to the number of Common Units subject to the corresponding award of Phantom Units multiplied by the Exchange Ratio, rounded down to the nearest whole unit, and (iii) in respect of the fractional phantom unit not received as a result of the rounding described in clause (ii) above, a cash payment, less applicable withholdings, equal to the applicable fractional amount multiplied by the closing price of a Parent Unit on the NYSE on the last trading day prior to the Closing Date. For the avoidance of doubt, any then-accumulated distribution equivalent amounts payable pursuant to distribution equivalent rights with respect to each Phantom Unit will carry over and be paid to the holder upon, and subject to, the vesting of the Converted Parent Phantom Unit that corresponds to the Phantom Unit to which such distribution equivalent amounts related.

(b) Treatment of Unit Options. Each Unit Option that is outstanding and “in-the-money” on the Closing Date (i.e., having a per unit exercise price greater than the closing price of a Common Unit on the NYSE on the last trading day prior to the Closing Date) immediately prior to the Effective Time (whether or not vested) shall be deemed to have been exercised on a net-issuance (i.e., cashless) basis immediately prior to the Effective Time and each net issued Common Unit deemed to have been issued will be converted into the right to receive the Merger Consideration pursuant to Section 2.1(a)(i) on the terms generally applicable to issued and outstanding Common Units, except as provided in this Section 2.3(b) (such consideration the “Option Consideration”). Unless a recipient of Option Consideration shall have remitted to Parent GP or its applicable Affiliate the amount required to be withheld with respect to the

payment of the Option Consideration under the Code or any provision of state, local or foreign tax Law, the Option Consideration to be received by such holder shall be reduced by the amount required to be deducted and withheld with respect to such payment. Such reduction shall come first from the Cash Consideration portion of the Option Consideration payable to the holder of the Unit Option (and from the cash payment, if any, described in the last sentence of this Section 2.3(b)), and if such amount is insufficient to satisfy the amount required to be deducted and withheld with respect to the payment of the Option Consideration, then the Unit Consideration portion of the Option Consideration shall be reduced by a number of Parent Units equal to (i) the remaining amount required to be deducted and withheld, divided by (ii) the closing price of one Parent Unit on the NYSE on the last trading day prior to the Closing Date. Subject to the foregoing but notwithstanding any other provision of this Agreement to the contrary, any Cash Consideration portion of the Option Consideration will be remitted to and paid through the ordinary payroll processes of the MLP GP or its successor or applicable Affiliate as soon as practicable after the Closing Date. Each outstanding Unit Option that is not “in-the-money” as of the Closing Date shall be mandatorily surrendered to the MLP and canceled and terminated at the Effective Time for no consideration. In the event that the deemed exercise described in this Section 2.3(b) would result in the holder of the Unit Option being deemed to hold a fractional Common Unit, that holder shall not receive such fractional unit and shall instead receive cash equal to the value of such fractional unit based on the closing price of a Common Unit on the NYSE on the last trading day prior to the Closing Date, less applicable withholdings.

(c) Treatment of Cash Units. Each award of Cash Units that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, cease to relate to or represent a right to receive an amount of cash based on the fair market value of the Common Units and shall be converted, at the Effective Time, into the right to receive (i) the Cash Consideration, (ii) an award of restricted cash units relating to Parent Units (a “Converted Parent Cash Unit Award”) on the same terms and conditions as were applicable to the corresponding award of Cash Units, except that the number of notional units that upon vesting entitles the holder to receive an amount of cash equal to the fair market value of a Parent Unit shall be equal to the number of notional Common Units related to the corresponding award of Cash Units multiplied by the Exchange Ratio, rounded down to the nearest whole unit, and (iii) in respect of the fractional restricted cash unit not received as a result of the rounding described in clause (ii) above, a cash payment, less applicable withholdings, equal to the applicable fractional amount multiplied by the closing price of a Parent Unit on the NYSE on the last trading day prior to the Closing Date. MLP Managing GP will cause the compensation committee of its board of directors to adopt prior to the Effective Time an amendment to the Regency Energy Partners LP Long-Term Incentive Cash Restricted Unit Plan to permit the treatment of Cash Units as provided herein.

(d) Assumption of MLP Equity Plans. As of the Effective Time, Parent shall assume the obligations of MLP under the MLP Equity Plans and shall assume such plans for purposes of employing such plans to make grants of equity based awards on Parent Units following the Closing.

Section 2.4 Adjustments. Notwithstanding any provision of this Article II to the contrary (but without in any way limiting the covenants in Section 5.2), if between the date of this Agreement and the Effective Time the number of outstanding Common Units, Class F Units,

Series A Units or Parent Units shall have been changed into a different number of units or a different class by reason of the occurrence or record date of any unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, combination, exchange of units or similar transaction, each of the Cash Consideration, the Exchange Ratio and the Series A Unit Consideration shall be appropriately adjusted to reflect fully the effect of such unit dividend, subdivision, reclassification, recapitalization, split, split-up, unit distribution, combination, exchange of units or similar transaction and to provide the holders of Common Units, Class F Units and Series A Units the same economic effect as contemplated by this Agreement prior to such event.

Section 2.5 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger, the GP Merger or the other transactions contemplated hereby.

Section 2.6 Effect of the GP Merger. By virtue of the GP Merger and without any action on the part of MLP GP, Parent GP or their respective partners: (i) the general partner interest and limited partner interest of MLP GP issued and outstanding immediately prior to the GP Merger Effective Time shall be canceled and cease to exist, and no former partner of MLP GP, in its capacity as such, shall have any partnership or other interest in the surviving limited partnership of the GP Merger, (ii) the general partner interest and limited partner interest of Parent GP issued and outstanding immediately prior to the GP Merger Effective Time shall not be affected and shall remain issued and outstanding as the partnership interests of the surviving limited partnership in the GP Merger, and (iii) the Parent Managing GP and ETE shall continue as the sole general partner and limited partner, respectively, of Parent GP following the GP Merger Effective Time. At the Effective Time, (x) the certificate of limited partnership of Parent GP as in effect immediately prior to the Effective Time shall remain unchanged and shall be the certificate of limited partnership of the surviving limited partnership in the GP Merger from and after the Effective Time, and thereafter may be amended as provided therein or by Law and (y) the agreement of limited partnership of Parent GP as in effect immediately prior to the Effective Time shall remain unchanged and shall be the agreement of limited partnership of the surviving limited partnership in the GP Merger from and after the Effective Time, and thereafter may be amended as provided therein or by Law.

(B) the MLP Managing GP Board (upon the recommendation of the MLP Conflicts Committee) has determined, after consultation with its outside legal counsel and financial advisors, that such MLP Alternative Proposal constitutes an MLP Superior Proposal after giving effect to all of the adjustments offered by Parent pursuant to clause (E) below;

(C) MLP has provided prior written notice to Parent in accordance with Section 8.9 (the “MLP Superior Proposal Notice”) of the MLP Managing GP Board’s intention to effect an MLP Adverse Recommendation Change, and such MLP Superior Proposal Notice has specified the identity of the Person making such MLP Alternative Proposal, the material terms and conditions of such MLP Alternative Proposal, and complete copies of any written proposal or offers (including proposed agreements) received by MLP in connection with such MLP Alternative Proposal;

(D) during the period that commences on the date of delivery of the MLP Superior Proposal Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day following the date of such delivery (the “MLP Superior Proposal Notice Period”), MLP shall (1) negotiate with Parent in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the MLP Managing GP Board not to effect an MLP Adverse Recommendation Change; and (2) keep Parent reasonably informed with respect to the status and changes in the material terms and conditions of such MLP Alternative Proposal or other change in circumstances related thereto; provided, however, that any material revisions to such MLP Alternative Proposal (it being agreed that any change in the purchase price in such MLP Alternative Proposal shall be deemed a material revision) shall require delivery of a subsequent MLP Superior Proposal Notice and a subsequent MLP Superior Proposal Notice Period in respect of such revised MLP Alternative Proposal, except that such subsequent MLP Superior Proposal Notice Period shall expire upon the later of (x) the end of the initial MLP Superior Proposal Notice Period and (y) 11:59 p.m. Central time on the date that is the third calendar day following the date of the delivery of such subsequent MLP Superior Proposal Notice; and

(E) the MLP Managing GP Board shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by Parent and, at the end of the MLP Superior Proposal Notice Period, shall have determined in good faith that (i) such MLP Alternative Proposal continues to constitute an MLP Superior Proposal even if such revisions were to be given effect and (ii) failure to

effect an MLP Adverse Recommendation Change would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law even if such revisions were to be given effect; or

(ii) if the MLP Managing GP Board intends to effect such MLP Adverse Recommendation Change in response to an MLP Changed Circumstance:

(A) MLP has provided prior written notice to Parent in accordance with Section 8.9 (the “MLP Recommendation Change Notice”) of the MLP Managing GP Board’s intention to effect an MLP Adverse Recommendation Change, and such MLP Recommendation Change Notice has specified the details of such MLP Changed Circumstance and the reasons for the MLP Adverse Recommendation Change;

(B) during the period that commences on the date of delivery of the MLP Recommendation Change Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day following the date of such delivery (the “MLP Recommendation Change Notice Period”), MLP shall (i) negotiate with Parent in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the MLP Managing GP Board not to effect an MLP Adverse Recommendation Change; and (ii) keep Parent reasonably informed of any change in circumstances related thereto; and

(C) the MLP Managing GP Board shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by Parent and, at the end of the MLP Adverse Recommendation Change Notice Period, shall have determined (upon the recommendation of the MLP Conflicts Committee) in good faith that the failure to effect an MLP Adverse Recommendation Change would be inconsistent with its duties under the MLP Partnership Agreement or applicable Law even if such revisions were to be given effect.

(e) Nothing contained in this Agreement shall prevent MLP or the MLP Managing GP Board from issuing a “stop, look and listen” communication pursuant to Rule 14d-9(f) under the Exchange Act or complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an MLP Alternative Proposal if the MLP Managing GP Board determines in good faith (after consultation with outside legal counsel) that its failure to do so would be reasonably likely to constitute a violation of applicable Law; provided that any MLP Adverse Recommendation Change may only be made in accordance with Section 5.3(d). For the avoidance of doubt, a public statement that describes MLP’s receipt of an MLP Alternative Proposal and the operation of this Agreement with respect thereto shall not be deemed an MLP Adverse Recommendation Change.

Section 5.4 No Solicitation by Parent; Etc.

(a) Parent shall, and shall cause its Subsidiaries and use reasonable best efforts to cause Parent’s and its Subsidiaries’ respective Representatives to, immediately cease and cause

to be terminated any discussions or negotiations with any Person conducted heretofore with respect to a Parent Alternative Proposal, request the return or destruction of all confidential information previously provided to such parties by or on behalf of Parent or its Subsidiaries and immediately prohibit any access by any Person (other than Parent and its Representatives) to any physical or electronic data room relating to a possible Parent Alternative Proposal. Except as permitted by this Section 5.4, (x) Parent shall not, and shall cause its Subsidiaries and use reasonable best efforts to cause its Representatives not to, directly or indirectly (i) solicit, initiate, knowingly facilitate, knowingly encourage (including by way of furnishing confidential information) or knowingly induce or take any other action intended to lead to any inquiries or any proposals that constitute the submission of a Parent Alternative Proposal, (ii) except for a confidentiality agreement permitted pursuant to Section 5.4(b), enter into any confidentiality agreement, merger agreement, letter of intent, agreement in principle, unit purchase agreement, asset purchase agreement or unit exchange agreement, option agreement or other similar agreement relating to a Parent Alternative Proposal (a “Parent Acquisition Agreement”), or (iii) withdraw, modify or qualify, or propose publicly to withdraw, modify or qualify, in a manner adverse to MLP, the Parent Board Recommendation or publicly recommend the approval or adoption of, or publicly approve or adopt, or propose to publicly recommend, approve or adopt, any Parent Alternative Proposal and (y) within five business days of receipt of a written request of MLP following the receipt by Parent of any Parent Alternative Proposal, Parent shall publicly reconfirm the Parent Board Recommendation; provided that, in the event that MLP requests such public reconfirmation of the Parent Board Recommendation, then Parent may not unreasonably withhold, delay (beyond the five business day period) or condition the public reconfirmation of the Parent Board Recommendation and provided, further that MLP shall not be permitted to make such request on more than one occasion in respect of each Parent Alternative Proposal and each material modification to a Parent Alternative Proposal, if any (the taking of any action described in clause (x)(iii) or the failure to take the action described in clause (y) being referred to as a “Parent Adverse Recommendation Change”). Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by Parent’s Subsidiaries or Representatives shall be deemed to be a breach of this Section 5.4 by Parent unless such violation is committed without the Knowledge of Parent and Parent uses its reasonable best efforts to promptly cure such violation once Parent is made aware of such violation.

(b) Notwithstanding anything to the contrary contained in Section 5.4(a), if at any time following the date of this Agreement and prior to obtaining the Parent Unitholder Approval, (i) Parent has received a written Parent Alternative Proposal that the Parent Managing GP Board (upon the recommendation of the Parent Conflicts Committee) believes is bona fide, (ii) the Parent Managing GP Board (upon the recommendation of the Parent Conflicts Committee), after consultation with its financial advisors and outside legal counsel, determines in good faith that (A) such Parent Alternative Proposal constitutes or could reasonably be expected to lead to or result in a Parent Superior Proposal and (B) failure to take such action would be inconsistent with its duties under the Parent Partnership Agreement or applicable Law and (iii) such Parent Alternative Proposal did not result from a material breach of this Section 5.4, then Parent may, subject to clauses (x) and (y) below, (A) furnish information, including confidential information, with respect to Parent and its Subsidiaries to the Person making such Parent Alternative Proposal and (B) participate in discussions or negotiations regarding such Parent Alternative Proposal; provided that (x) Parent will not, and will use reasonable best efforts to cause its Representatives not to, disclose any non-public information to such Person unless Parent has, or first enters into,

a confidentiality agreement with such Person with confidentiality provisions that are not less restrictive to such Person than the provisions of the Parent Confidentiality Agreement are to MLP and (y) Parent will provide to MLP non-public information about Parent or its Subsidiaries that was not previously provided or made available to MLP prior to or substantially concurrently with providing or making available such non-public information to such other Person.

(c) In addition to the other obligations of Parent set forth in this Section 5.4, Parent shall promptly advise MLP, orally and in writing, and in no event later than 24 hours after receipt, if any proposal, offer, inquiry or other contact is received by, any information is requested from, or any discussions or negotiations are sought to be initiated or continued with, Parent in respect of any Parent Alternative Proposal, and shall, in any such notice to MLP, indicate the identity of the Person making such proposal, offer, inquiry or other contact and the terms and conditions of any proposals or offers or the nature of any inquiries or contacts (and shall include with such notice copies of any written materials received from or on behalf of such Person relating to such proposal, offer, inquiry or request), and thereafter shall promptly keep MLP reasonably informed of all material developments affecting the status and terms of any such proposals, offers, inquiries or requests (and Parent shall promptly provide MLP with copies of any additional written materials received by Parent or that Parent has delivered to any third party making a Parent Alternative Proposal that relate to such proposals, offers, inquiries or requests) and of the status of any such discussions or negotiations.

(d) Notwithstanding any other provision of this Agreement, at any time prior to obtaining the Parent Unitholder Approval, the Parent Managing GP Board and the Parent Conflicts Committee may effect a Parent Adverse Recommendation Change in response to a Parent Alternative Proposal or a Parent Changed Circumstance if the Parent Managing GP Board (upon the recommendation of the Parent Conflicts Committee), after consultation with its outside legal counsel and financial advisors, determines in good faith that the failure to take such action would be inconsistent with its duties under the Parent Partnership Agreement or applicable Law and:

(i) if the Parent Managing GP Board (upon the recommendation of the Parent Conflicts Committee) intends to effect such Parent Adverse Recommendation Change in response to a Parent Alternative Proposal:

(A) such Parent Alternative Proposal is bona fide, in writing and has not been withdrawn or abandoned;

(B) the Parent Managing GP Board (upon the recommendation of the Parent Conflicts Committee) has determined, after consultation with its outside legal counsel and financial advisors, that such Parent Alternative Proposal constitutes a Parent Superior Proposal after giving effect to all of the adjustments offered by MLP pursuant to clause (E) below;

(C) Parent has provided prior written notice to MLP in accordance with Section 8.9 (the “Parent Superior Proposal Notice”) of the Parent Managing GP Board’s intention to effect a Parent Adverse Recommendation Change, and such Parent Superior Proposal Notice has specified the identity of the Person

making such Parent Alternative Proposal, the material terms and conditions of such Parent Alternative Proposal, and complete copies of any written proposal or offers (including proposed agreements) received by Parent in connection with such Parent Alternative Proposal;

(D) during the period that commences on the date of delivery of the Parent Superior Proposal Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day following the date of such delivery (the “Parent Superior Proposal Notice Period”), Parent shall (1) negotiate with MLP in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the Parent Managing GP Board not to effect a Parent Adverse Recommendation Change; and (2) keep MLP reasonably informed with respect to the status and changes in the material terms and conditions of such Parent Alternative Proposal or other change in circumstances related thereto; provided, however, that any material revisions to such Parent Alternative Proposal (it being agreed that any change in the purchase price in such Parent Alternative Proposal shall be deemed a material revision) shall require delivery of a subsequent Parent Superior Proposal Notice and a subsequent Parent Superior Proposal Notice Period in respect of such revised Parent Alternative Proposal, except that such subsequent Parent Superior Proposal Notice Period shall expire upon the later of (x) the end of the initial Parent Superior Proposal Notice Period and (y) 11:59 p.m. Central time on the date that is the third calendar day following the date of the delivery of such subsequent Parent Superior Proposal Notice; and

(E) the Parent Managing GP Board shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by MLP and, at the end of the Parent Superior Proposal Notice Period, shall have determined in good faith that (i) such Alternative Proposal continues to constitute a Parent Superior Proposal even if such revisions were to be given effect and (ii) failure to effect a Parent Adverse Recommendation Change would be inconsistent with its duties under the Parent Partnership Agreement or applicable Law even if such revisions were to be given effect; or

(ii) if the Parent Managing GP Board intends to effect such Parent Adverse Recommendation Change in response to a Parent Changed Circumstance:

(A) Parent has provided prior written notice to MLP in accordance with Section 8.9 (the “Parent Recommendation Change Notice”) of the Parent Managing GP Board’s intention to effect a Parent Adverse Recommendation Change, and such Parent Recommendation Change Notice has specified the details of such Parent Changed Circumstance and the reasons for the Parent Adverse Recommendation Change;

(B) during the period that commences on the date of delivery of the Parent Recommendation Change Notice as determined in accordance with Section 8.9 and ends at 11:59 p.m. Central time on the date that is the fifth calendar day

following the date of such delivery (the “Parent Recommendation Change Notice Period”), Parent shall (i) negotiate with MLP in good faith to make such adjustments to the terms and conditions of this Agreement as would permit the Parent Managing GP Board not to effect a Parent Adverse Recommendation Change; and (ii) keep MLP reasonably informed of any change in circumstances related thereto; and

(C) the Parent Managing GP Board shall have considered all revisions to the terms of this Agreement irrevocably offered in writing by MLP and, at the end of the Parent Adverse Recommendation Change Notice Period, shall have determined (upon the recommendation of the Parent Conflicts Committee) in good faith that the failure to effect a Parent Adverse Recommendation Change would be inconsistent with its duties under the Parent Partnership Agreement or applicable Law even if such revisions were to be given effect.

(e) Nothing contained in this Agreement shall prevent Parent or the Parent Managing GP Board from issuing a “stop, look and listen” communication pursuant to Rule 14d-9(f) under the Exchange Act or complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to a Parent Alternative Proposal if the Parent Managing GP Board determines in good faith (after consultation with outside legal counsel) that its failure to do so would be reasonably likely to constitute a violation of applicable Law; provided that any Parent Adverse Recommendation Change may only be made in accordance with Section 5.4(d). For the avoidance of doubt, a public statement that describes Parent’s receipt of a Parent Alternative Proposal and the operation of this Agreement with respect thereto shall not be deemed a Parent Adverse Recommendation Change.

Section 5.5 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement (including Section 5.5(d)), each of the Parent Entities, on the one hand, and the MLP Entities, on the other hand, shall cooperate with the other and use (and shall cause their respective Subsidiaries to use) its reasonable best efforts to (i) take, or cause to be taken, all actions, and do, or cause to be done, all things, necessary, proper or advisable to cause the conditions to the Closing to be satisfied as promptly as practicable (and in any event no later than the Outside Date) and to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated hereby, including preparing and filing promptly and fully all documentation to effect all necessary filings, notifications, notices, petitions, statements, registrations, submissions of information, applications and other documents (including any required or recommended filings under applicable Antitrust Laws), (ii) obtain promptly (and in any event no later than the Outside Date) all approvals, consents, clearances, expirations or terminations of waiting periods, registrations, permits, authorizations and other confirmations from any Governmental Authority or third party necessary, proper or advisable to consummate the transactions contemplated hereby, (iii) defend any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby or seek to have lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby and (iv) obtain all necessary consents, approvals or waivers from third parties.

(b) In furtherance and not in limitation of the foregoing, (i) each party hereto (including by their respective Subsidiaries) agrees to make an appropriate filing (if required) of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable and in any event within 15 business days after the date of this Agreement (unless a later date is mutually agreed to by the parties hereto) and to supply as promptly as practicable any additional information and documentary material that may be requested by any Governmental Authority pursuant to the HSR Act or any other Antitrust Law and use its reasonable best efforts to take, or cause to be taken (including by their respective Subsidiaries), all other actions consistent with this Section 5.5 necessary to cause the expiration or termination of any applicable waiting periods under the HSR Act as soon as practicable (and in any event no later than the Outside Date); and (ii) MLP and Parent shall each use its reasonable best efforts to (x) take all action necessary to ensure that no state takeover statute or similar Law is or becomes applicable to any of the transactions contemplated hereby and (y) if any state takeover statute or similar Law becomes applicable to any of the transactions contemplated hereby, take all action necessary to ensure that such transaction may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise minimize the effect of such Law on the transaction.

(c) Each of the parties hereto shall use (and shall cause their respective Subsidiaries to use) its reasonable best efforts to (i) cooperate in all respects with each other in connection with any filing or submission with a Governmental Authority in connection with the transactions contemplated hereby, including by providing the other parties a reasonable opportunity to review and comment thereon, and in connection with any investigation or other inquiry by or before a Governmental Authority relating to the transactions contemplated hereby, including any proceeding initiated by a private Person, (ii) promptly inform the other party of (and supply to the other party) any communication received by such party from, or given by such party to, the Federal Trade Commission, the Antitrust Division of the Department of Justice, or any other Governmental Authority and any material communication received or given in connection with any proceeding by a private Person, in each case regarding any of the transactions contemplated hereby, (iii) permit the other party to review in advance and incorporate the other party’s reasonable comments in any communication to be given by it to any Governmental Authority with respect to obtaining any clearances required under any Antitrust Law in connection with the transactions contemplated hereby and (iv) consult with the other party in advance of any meeting or teleconference with any Governmental Authority or, in connection with any proceeding by a private Person, with any other Person, and, to the extent not prohibited by the Governmental Authority or other Person, give the other party the opportunity to attend and participate in such meetings and teleconferences. Parent shall have the principal responsibility for devising and implementing the strategy for obtaining any clearances required under any Antitrust Law in connection with the transactions contemplated hereby and shall take the lead in all meetings and communications with any Governmental Authority in connection with obtaining such clearances, provided, however, that Parent shall consult in advance with MLP and in good faith take MLP’s views into account regarding the overall strategy. Subject to Section 5.7(b), the parties shall take reasonable efforts to share information protected from disclosure under the attorney-client privilege, work product doctrine, joint defense privilege or any other privilege pursuant to this Section 5.5 in a manner so as to preserve the applicable privilege.

(d) Parent and MLP (including by causing their respective Subsidiaries) agree to use their reasonable best efforts to (x) resolve any objections that a Governmental Authority or other Person may assert under any Antitrust Law with respect to the transactions contemplated hereby, and (y) avoid or eliminate each and every impediment under any Antitrust Law that may be asserted by any Governmental Authority with respect to the transactions contemplated hereby, in each case, so as to enable the Closing to occur as promptly as practicable and in any event no later than the Outside Date, and including offering, accepting and agreeing to (A) dispose or hold separate any part of MLP’s, Parent’s or their respective Subsidiaries’ businesses, operations or assets (or a combination thereof), (B) not compete in any geographic area or line of business, and/or (C) restrict the manner in which, or whether, Parent, MLP or any of their respective Subsidiaries may carry on business in any part of the world. MLP shall not, without Parent’s prior written consent, commit to any disposal, hold separate, or other restriction related to its or its Subsidiaries’ businesses, operations or assets.

Section 5.6 Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by Parent and MLP. Thereafter, neither MLP nor Parent shall issue or cause the publication of any press release or other public announcement (to the extent not previously issued or made in accordance with this Agreement) with respect to this Agreement or the transactions contemplated hereby without the prior consent of the other party (which consent shall not be unreasonably withheld or delayed), except as may be required by Law or by any applicable listing agreement with the NYSE or other national securities exchange as determined in the good faith judgment of the party proposing to make such release (in which case such party shall not issue or cause the publication of such press release or other public announcement without prior consultation with the other party); provided, however, that (a) MLP shall not be required by this Section 5.6 to consult with any other party with respect to a public announcement in connection with the receipt and existence of an MLP Alternative Proposal that the MLP Managing GP Board (upon the recommendation of the MLP Conflicts Committee) believes is bona fide and matters related thereto or an MLP Adverse Recommendation Change but nothing in this clause (a) shall limit any obligation of MLP under Section 5.3(d) to negotiate with Parent in good faith and (b) Parent shall not be required by this Section 5.6 to consult with any other party with respect to a public announcement in connection with the receipt and existence of a Parent Alternative Proposal that the Parent Managing GP Board (upon the recommendation of the Parent Conflicts Committee) believes is bona fide and matters related thereto or a Parent Adverse Recommendation Change but nothing in this clause (b) shall limit any obligation of Parent under Section 5.4(d) to negotiate with MLP in good faith; provided, further, that each party and their respective controlled affiliates may make statements that are consistent with statements made in previous press releases, public disclosures or public statements made by Parent or MLP in compliance with this Section 5.6.

Section 5.7 Access to Information; Confidentiality.

(a) Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each party shall, and shall cause each of its Subsidiaries to afford to the other party and its Representatives reasonable access during normal business hours (and, with respect to books and records, the right to copy) to all of its and its Subsidiaries’ properties, commitments, books, Contracts, records and correspondence (in each case, whether in physical or electronic

form), officers, employees, accountants, counsel, financial advisors and other Representatives. Each party shall furnish promptly to the other party (i) a copy of each report, schedule and other document filed or submitted by it pursuant to the requirements of federal or state securities Laws and a copy of any communication (including “comment letters”) received by such party from the SEC concerning compliance with securities Laws and (ii) all other information concerning its and its Subsidiaries’ business, properties and personnel as the other party may reasonably request (including information necessary to prepare the Proxy Statement). Except for disclosures permitted by the terms of the Confidentiality Agreement, dated as of January 16, 2015, between Parent and MLP (as it may be amended from time to time, the “Parent Confidentiality Agreement”), each party and its Representatives shall hold information received from the other party pursuant to this Section 5.7 in confidence in accordance with the terms of the Parent Confidentiality Agreement.

(b) This Section 5.7 shall not require either party to permit any access, or to disclose any information, that in the reasonable, good faith judgment (after consultation with counsel, which may be in-house counsel) of such party would reasonably be expected to result in (i) any violation of any contract or Law to which such party or its Subsidiaries is a party or is subject or cause any privilege (including attorney-client privilege) that such party or any of its Subsidiaries would be entitled to assert to be undermined with respect to such information and such undermining of such privilege could in such party’s good faith judgment (after consultation with counsel, which may be in-house counsel) adversely affect in any material respect such party’s position in any pending or, what such party believes in good faith (after consultation with counsel, which may be in-house counsel) could be, future litigation or (ii) if such party or any of its Subsidiaries, on the one hand, and the other party or any of its Subsidiaries, on the other hand, are adverse parties in a litigation, such information being reasonably pertinent thereto; provided that, in the case of clause (i), the parties hereto shall cooperate in seeking to find a way to allow disclosure of such information (including by entering into a joint-defense or similar agreement) to the extent doing so (1) would not (in the good faith belief of the party being requested to disclose the information (after consultation with counsel, which may be in-house counsel)) reasonably be likely to result in the violation of any such contract or Law or reasonably be likely to cause such privilege to be undermined with respect to such information or (2) could reasonably (in the good faith belief of the party being requested to disclose the information (after consultation with counsel, which may be in-house counsel)) be managed through the use of customary “clean-room” arrangements pursuant to which appropriately designated Representatives of the other party shall be provided access to such information; provided, further, that the party being requested to disclose the information shall (x) notify the other party that such disclosures are reasonably likely to violate its or its Subsidiaries’ obligations under any such contract or Law or are reasonably likely to cause such privilege to be undermined, (y) communicate to the other party in reasonable detail the facts giving rise to such notification and the subject matter of such information (to the extent it is able to do so in accordance with the first proviso in this Section 5.7(b)) and (z) in the case where such disclosures are reasonably likely to violate its or its Subsidiaries’ obligations under any contract, use reasonable commercial efforts to seek consent from the applicable third party to any such contract with respect to the disclosures prohibited thereby (to the extent not otherwise expressly prohibited by the terms of such contract).

(c) No investigation, or information received, pursuant to this Section 5.7 will modify any of the representations and warranties of the parties hereto.

MLP shall give prompt notice to Parent, and Parent shall give prompt notice to MLP, of (i) any notice or other communication received by such party from any Governmental Authority in connection with the transactions contemplated hereby or from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby, if the subject matter of such communication or the failure of such party to obtain such consent is reasonably likely to be material to MLP or Parent, (ii) any actions, suits, claims, investigations or proceedings commenced or, to such party’s knowledge, threatened against, relating to or involving or otherwise affecting such party or any of its Subsidiaries and that relate to the transactions contemplated hereby, (iii) the discovery of any fact or circumstance that, or the occurrence or non-occurrence of any event the occurrence or non-occurrence of which, would result in the failure to be satisfied of any of the conditions to the Closing in Article VI and (iv) any material failure of such party to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereby which would result in the failure to be satisfied of any of the conditions to the Closing in Article VI; provided that, in the case of clauses (iii) and (iv), the failure to comply with this Section 5.8 shall not result in the failure to be satisfied of any of the conditions to the Closing in Article VI, or give rise to any right to terminate this Agreement under Article VII, if the underlying fact, circumstance, event or failure would not in and of itself give rise to such failure or right.

Section 5.9 Indemnification and Insurance.

(a) For purposes of this Section 5.9, (i) “Indemnified Person” shall mean any person who is now, or has been or becomes at any time prior to the Effective Time, an officer or director of MLP, MLP GP or any of their respective Subsidiaries and also with respect to any such Person, in their capacity as a director, officer, employee, member, trustee or fiduciary of another corporation, foundation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise (whether or not such other entity or enterprise is affiliated with MLP) serving at the request of or on behalf of MLP, MLP GP or any of their respective Subsidiaries and together with such Person’s heirs, executors or administrators and (ii) “Proceeding” shall mean any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative, investigative or otherwise and whether or not such claim, action, suit, proceeding or investigation results in a formal civil or criminal litigation or regulatory action.

(b) From and after the Effective Time, to the fullest extent that MLP, MLP GP or any applicable Subsidiary thereof would be permitted to indemnify an Indemnified Person, Parent and Parent GP agree to (i) indemnify and hold harmless against any cost or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages or liabilities and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) in connection with any Proceeding, and provide advancement promptly, and in any event within 10 days after any written request, of expenses to, all Indemnified Persons to the fullest extent permitted under applicable Law and (ii) honor the provisions regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses contained in the MLP Charter Documents and

comparable governing instruments of MLP GP and any Subsidiary of MLP or MLP GP immediately prior to the Effective Time and ensure that the organizational documents of the Surviving Entity and Parent GP shall, for a period of six years following the Effective Time, contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors, officers and agents of MLP, MLP GP and their respective Subsidiaries than are presently set forth in the MLP Charter Documents and comparable governing instruments of MLP GP (it being acknowledged and agreed that the provisions of the Parent Charter Documents and comparable governing instruments of MLP GP currently in effect are no less favorable with respect to indemnification, advancement of expenses and exculpation of such Persons than are presently in the MLP Charter Documents and comparable governing instruments of MLP GP). Any right of indemnification of an Indemnified Person pursuant to this Section 5.9(b) shall not be amended, repealed or otherwise modified at any time in a manner that would adversely affect the rights of such Indemnified Person as provided herein.

(c) The Surviving Entity and Parent GP shall maintain in effect for six years from the Effective Time MLP’s and MLP GP’s current directors’ and officers’ liability insurance policies covering acts or omissions occurring at or prior to the Effective Time with respect to Indemnified Persons (provided that the Surviving Entity or Parent GP may substitute therefor policies with reputable carriers of at least the same coverage containing terms and conditions that are no less favorable to the Indemnified Persons); provided, however, that in no event shall the Surviving Entity or Parent GP be required to expend pursuant to this Section 5.9(c) more than an amount per year equal to 300% of current annual premiums paid by MLP or MLP GP for such insurance (the “Maximum Amount”). In the event that, but for the proviso to the immediately preceding sentence, the Surviving Entity or Parent GP would be required to expend more than the Maximum Amount, the Surviving Entity or Parent GP shall obtain the maximum amount of such insurance as is available for the Maximum Amount. If MLP or MLP GP in its sole discretion elects, then, in lieu of the obligations of Parent and Parent GP under this Section 5.9(c), MLP or MLP GP may, prior to the Effective Time, purchase a “tail policy” with respect to acts or omissions occurring or alleged to have occurred prior to the Effective Time that were committed or alleged to have been committed by such Indemnified Persons in their capacity as such; provided that in no event shall the cost of such policy exceed six times the Maximum Amount.

(d) The rights of any Indemnified Person under this Section 5.9 shall be in addition to any other rights such Indemnified Person may have under the organizational documents of MLP, MLP GP, MLP Managing GP, the Surviving Entity, Parent GP, Parent Managing GP, the DRULPA or the DLLCA. The provisions of this Section 5.9 shall survive the consummation of the transactions contemplated hereby for a period of six years and are expressly intended to benefit each of the Indemnified Persons and their respective heirs and representatives; provided, however, that in the event that any claim or claims for indemnification or advancement set forth in this Section 5.9 are asserted or made within such six-year period, all rights to indemnification and advancement in respect of any such claim or claims shall continue until disposition of all such claims. If the Surviving Entity, Parent GP or any of their respective successors or assigns (i) consolidates with or merges into any other Person, or (ii) transfers or conveys all or substantially all of their businesses or assets to any other Person, then, in each such case, to the extent necessary, a proper provision shall be made so that the successors and assigns of the Surviving Entity or Parent GP, as the case may be, shall assume the obligations of the Surviving Entity and Parent GP set forth in this Section 5.9.

Section 5.10 Securityholder Litigation. MLP shall give Parent the opportunity to participate in the defense or settlement of any securityholder litigation against MLP and/or its officers and directors relating to the transactions contemplated hereby; provided that MLP shall in any event control such defense and/or settlement (subject to Section 5.2(a)(xiii)) and shall not be required to provide information if doing so would be reasonably expected to threaten the loss of any attorney-client privilege or other applicable legal privilege.

Section 5.11 Financing Matters.

(a) MLP shall, at the request of Parent, (i) call for prepayment or redemption, or prepay or redeem, (ii) attempt to renegotiate the terms of, (iii) commence an offer to purchase and/or consent solicitation or (iv) satisfy and discharge or defease any then-existing indebtedness for borrowed money of MLP; provided, however, that MLP shall not be obligated to make or cause to become effective any such action (nor shall MLP be required to incur any cost or liability in respect thereof) prior to the Effective Time. Parent shall prepare all necessary and appropriate documentation in connection with any action described above, and provide MLP with a reasonable opportunity to comment on such documents. Parent and MLP shall, and shall cause their respective Subsidiaries and Representatives to, reasonably cooperate with each other in the preparation of such documents.
