Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions of this Section 4.5(b) , the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Certificates evidencing Limited Partner Interests for which a

Transfer Agent has been appointed, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered. Upon the proper surrender of a Certificate, such transfer shall be recorded in the Partnership Register.

(c)    Upon the receipt of proper transfer instructions from the Record Holder of uncertificated Partnership Interests, such transfer shall be recorded in the Partnership Register.

(d)    Except as provided in Section 4.9 , by acceptance of any Limited Partner Interests pursuant to a transfer in accordance with this Article IV, each transferee of a Limited Partner Interest (including any nominee, or agent or representative acquiring such Limited Partner Interests for the account of another Person or Group) (i) shall be admitted to the Partnership as a Limited Partner with respect to the Limited Partner Interests so transferred to such Person when any such transfer or admission is reflected in the Partnership Register and such Person becomes the Record Holder of the Limited Partner Interests so transferred, (ii) shall become bound, and shall be deemed to have agreed to be bound, by the terms of this Agreement, (iii) represents that the transferee has the capacity, power and authority to enter into this Agreement, (iv) makes the consents, acknowledgements and waivers contained in this Agreement, all with or without execution of this Agreement by such Person and (v) shall be deemed to certify that the transferee is not an Ineligible Holder. The transfer of any Limited Partner Interests and the admission of any new Limited Partner shall not constitute an amendment to this Agreement.

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

(f)    The General Partner and its Affiliates shall have the right at any time to transfer their Common Units to one or more Persons.

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

(a)    Subject to Section 4.6(c) below, prior to December 31, 2022, the General Partner shall not transfer all or any part of its General Partner Interest to a Person unless such transfer (i) has been approved by the prior written consent or vote of the holders of a majority of the Voting Eligible Common Units (excluding Common Units owned by the General Partner and its Affiliates) and Series A Preferred Units (as described in Section 5.14(b)(iii)(A) ) voting together as a single class, (ii) is of all, but not less than all, of its General Partner Interest to (A) an Affiliate of the General Partner (other than an individual) or (B) another Person (other than an individual) in connection with the merger or consolidation of the General Partner with or into such other Person or the transfer by the General Partner of all or substantially all of its assets to such other Person or (iii) is pursuant to a bona fide foreclosure by the lenders under any debt instrument with respect to which the General Partner is an obligor or guarantor.

(b)    Subject to Section 4.6(c) below, on or after December 31, 2022, the General Partner may transfer all or any part of its General Partner Interest without the approval of any Limited Partner or any other Person.

(c)    Notwithstanding anything herein to the contrary, no transfer by the General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and to be bound by the provisions of this Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner under the Delaware Act or cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate portion thereof, if applicable) of the partnership or membership interest owned by the General Partner as the general partner or managing member, if any, of each other Group Member. In the case of a transfer pursuant to and in compliance with this Section 4.6 , the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.2 , be admitted to the Partnership as the General Partner effective immediately prior to the transfer of the General Partner Interest, and the business of the Partnership shall continue without dissolution.

Section 4.7    [Reserved.]

Section 4.8     Restrictions on Transfers .

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

(b)    The General Partner may impose restrictions on the transfer of Partnership Interests if it receives an Opinion of Counsel that such restrictions are necessary to (i) avoid a significant risk of the Partnership’s becoming taxable as a corporation or otherwise becoming taxable as an entity for federal income tax purposes (to the extent not already so treated or taxed) or (ii) preserve the uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may impose such restrictions by amending this Agreement; provided , however , that any amendment that would result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then listed or admitted to trading must be approved, prior to such amendment being effected, by the holders of a majority of the Voting Eligible Limited Partner Interests of such class.

(c)    [Reserved.]

(d)    [Reserved.]

(e)    Except for Section 4.9 , nothing in this Agreement shall preclude the settlement of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading.

(f)    Each certificate or book entry evidencing Partnership Interests shall bear a conspicuous legend in substantially the following form:

THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF MPLX LP THAT THIS SECURITY MAY NOT BE TRANSFERRED IF SUCH TRANSFER (AS DEFINED IN THE PARTNERSHIP AGREEMENT) WOULD (A) VIOLATE THE THEN APPLICABLE FEDERAL OR STATE SECURITIES LAWS OR RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER GOVERNMENTAL AUTHORITY WITH JURISDICTION OVER SUCH TRANSFER, (B) TERMINATE THE EXISTENCE OR QUALIFICATION OF MPLX LP UNDER THE LAWS OF THE STATE OF DELAWARE, OR (C) CAUSE MPLX LP TO BE TREATED AS AN ASSOCIATION TAXABLE AS A CORPORATION OR OTHERWISE TO BE TAXED AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES (TO THE EXTENT NOT ALREADY SO TREATED OR TAXED). THE GENERAL PARTNER OF MPLX LP MAY IMPOSE ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO AVOID A SIGNIFICANT RISK OF MPLX LP BECOMING TAXABLE AS A CORPORATION OR OTHERWISE BECOMING TAXABLE AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES. THIS SECURITY MAY BE SUBJECT TO ADDITIONAL RESTRICTIONS ON ITS TRANSFER PROVIDED IN THE PARTNERSHIP AGREEMENT. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS SECURITY TO THE SECRETARY OF THE GENERAL PARTNER AT THE PRINCIPAL EXECUTIVE OFFICES OF THE PARTNERSHIP. THE RESTRICTIONS SET FORTH ABOVE SHALL NOT PRECLUDE THE SETTLEMENT OF ANY TRANSACTIONS INVOLVING THIS SECURITY ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY IS LISTED OR ADMITTED TO TRADING.

(g)    [Reserved.]

(h)    [Reserved.]

(i)    The transfer of Series A Preferred Units shall be subject to the restrictions imposed by Section 5.14(b)(viii) .

Section 4.9     Eligibility Certificates; Ineligible Holders .

(a)    The General Partner may upon demand or on a regular basis require Limited Partners, and transferees of Limited Partner Interests in connection with a transfer, to execute an Eligibility Certificate or provide other information as is necessary for the General Partner to determine if any such Limited Partners or transferees are Ineligible Holders.

(b)    If any Limited Partner (or its beneficial owners) fails to furnish to the General Partner within 30 days of its request an Eligibility Certificate and other information related thereto, or if upon receipt of such Eligibility Certificate or other requested information the General Partner determines that a Limited Partner or a transferee of a Limited Partner is an Ineligible Holder, the Limited Partner Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions of Section 4.10 or the General Partner may refuse to effect the transfer of the Limited Partner Interests to such transferee. In addition, the General Partner shall be substituted for any Limited Partner that is an Ineligible Holder as the Limited Partner in respect of the Ineligible Holder’s Limited Partner Interests.

(c)    The General Partner shall, in exercising voting rights in respect of Limited Partner Interests held by it on behalf of Ineligible Holders, distribute the votes in the same ratios as the votes of Limited Partners (including the General Partner and its Affiliates) in respect of Limited Partner Interests other than those of Ineligible Holders are cast, either for, against or abstaining as to the matter.

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

(e)    At any time after an Ineligible Holder can and does certify that it no longer is an Ineligible Holder, it may, upon application to the General Partner, request that with respect to any Limited Partner Interests of such Ineligible Holder not redeemed pursuant to Section 4.10 , such Ineligible Holder upon approval of the General Partner, shall no longer constitute an Ineligible Holder and the General Partner shall cease to be deemed to be the Limited Partner in respect of such Limited Partner Interests.

(f)    If at any time a transferee of a Partnership Interest fails to furnish an Eligibility Certificate or any other information requested by the General Partner pursuant to Section 4.9 within 30 days of such request, or if upon receipt of such Eligibility Certificate or other information the General Partner determines, with the advice of counsel, that such transferee is an Ineligible Holder, the Partnership may, unless the transferee establishes to the satisfaction of the General Partner that such transferee is not an Ineligible Holder, prohibit and void the transfer, including by placing a stop order with the Transfer Agent.

Section 4.10     Redemption of Partnership Interests of Ineligible Holders .

(a)    If at any time a Limited Partner (other than a Series B Preferred Unitholder) fails to furnish an Eligibility Certificate or any other information requested within the period of time specified in Section 4.9 , or if upon receipt of such Eligibility Certificate or other information the General Partner determines, with the advice of counsel, that a Limited Partner (other than a Series B Preferred Unitholder) is an Ineligible Holder, the Partnership may, unless the Limited Partner establishes to the satisfaction of the General Partner that such Limited Partner is not an Ineligible Holder or has transferred his Limited Partner Interests to a Person who is not an Ineligible Holder and who furnishes an Eligibility Certificate to the General Partner prior to the date fixed for redemption as provided below, redeem the Limited Partner Interest of such Limited Partner as follows:

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

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

(iii)    The Limited Partner or such Limited Partner’s duly authorized representative shall be entitled to receive the payment for the Redeemable Interests at the place of payment specified in the notice of redemption on the redemption date (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender by or on behalf of the Limited Partner or Transferee at the place specified in the notice of redemption, of the Certificate evidencing the Redeemable Interests, duly endorsed in blank or accompanied by an assignment duly executed in blank).

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

(b)    The provisions of this Section 4.10 shall also be applicable to Limited Partner Interests held by a Limited Partner as nominee, agent or representative of a Person determined to be an Ineligible Holder.

(c)    Nothing in this Section 4.10 shall prevent the recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement and the transferor provides notice of such transfer to the General Partner. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner that such transferee is not an Ineligible Holder. If the transferee fails to make such certification within 30 days after the request and, in any event, before the redemption date, such redemption shall be effected from the transferee on the original redemption date.

ARTICLE V

CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS

Section 5.1    [Reserved]

Section 5.2     Contributions by the General Partner . Except as provided for in Section 12.8 , the General Partner is not obligated to make any additional Capital Contributions to the Partnership.

Section 5.3     Contributions by Limited Partner . No Limited Partner will be required to make any additional Capital Contribution to the Partnership pursuant to this Agreement.

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

Section 5.5     Capital Accounts .

(a)    The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee, agent or representative in any case in which such nominee, agent or representative has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall in respect of each such Partnership Interest be increased by (i) the amount of all Capital Contributions made to the Partnership with respect to such Partnership Interest and (ii) all items of Partnership income and gain (including income and gain exempt from tax) computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1 , and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property made with respect to such Partnership Interest; provided that the Capital Account of a holder of Series B Preferred Units shall not be reduced by the amount of Series B Distributions it receives and (y) all items of Partnership deduction and loss computed in accordance with Section 5.5(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1 . For the avoidance of doubt, the Series A Preferred Units will be treated as a partnership interest in the Partnership that is “convertible equity” within the meaning of Treasury Regulation Section 1.721-2(g)(3), and, therefore, each holder of a Series A Preferred Unit will be treated as a partner in the Partnership. The initial Capital Account balance in respect of each Series A Preferred Unit shall be the Series A Issue Price, as such amount may be adjusted in accordance with the Series A Purchase Agreement for any reduction attributable to the Transaction Fee, as such term is defined in the Series A Purchase Agreement and expenses reimbursable under the Series A Purchase Agreement. The initial Capital Account balance in respect of each Series B Preferred Unit shall be the Series B Liquidation Preference. The Capital Account balance of each holder of Series B Preferred Units in respect of its Series B Preferred Units shall not be increased or decreased as a result of the accrual and accumulation of an unpaid distribution pursuant to Section 5.15(b)(i) in respect of such Series B Preferred Units.

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

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

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

(iii)    Except as otherwise provided in this Agreement or Treasury Regulation Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code that may be made by the Partnership. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment in the Capital Accounts shall be treated as an item of gain or loss.

(iv)    In the event the Carrying Value of Partnership property is adjusted pursuant to Section 5.5(d)(i) , any Unrealized Gain resulting from such adjustment shall be treated as an item of gain and any Unrealized Loss resulting from such adjustment shall be treated as an item of loss.

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

(vi)    An item of income of the Partnership that is described in Section 705(a)(1)(B) of the Code (with respect to items of income that are exempt from tax) shall be treated as an item of income for the purpose of this Section 5.5(b), and an item of expense of the Partnership that is described in Section 705(a)(2)(B) of the Code (with respect to expenditures that are not deductible and not chargeable to capital accounts), shall be treated as an item of deduction for the purpose of this Section 5.5(b) .

(vii)    In accordance with the requirements of Section 704(b) of the Code, any deductions for depreciation, cost recovery or amortization attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Partnership were equal to the Agreed Value of such property. Upon an adjustment pursuant to Section 5.5(d)(i) to the Carrying Value of any Partnership property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization attributable to such property shall be determined under the rules prescribed by Treasury Regulation Section 1.704-3(d)(2) as if the adjusted basis of such property were equal to the Carrying Value of such property immediately following such adjustment.

(viii)    To the extent required by Treasury Regulation Section 1.752-7, the Gross Liability Value of each Liability of the Partnership described in Treasury Regulation Section 1.752-7(b)(3)(i) shall be adjusted at such times as provided in this Agreement for an adjustment to Carrying Values. The amount of any such adjustment shall be treated for purposes hereof as an item of loss (if the adjustment increases the Carrying Value of such Liability of the Partnership) or an item of gain (if the adjustment decreases the Carrying Value of such Liability of the Partnership).

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

(d)    (i)    In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Partnership Interests for cash or Contributed Property or the issuance of Partnership Interests as consideration for the provision of services, the Carrying Value of each Partnership property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property; provided, however, that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed Property, or in the event of an issuance of a de minimis amount of Partnership Interests as consideration for the provision of services, the General Partner may determine that such adjustments are unnecessary for the proper administration of the Partnership. In determining such Unrealized Gain or Unrealized Loss, the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to the issuance of additional Partnership Interests shall be determined by the General Partner using such method of valuation as it may adopt. In making its determination of the fair market values of individual properties, the General Partner may determine that it is appropriate to first determine an aggregate value for the Partnership, derived from the current trading price of the Common Units, and taking fully into account the fair market value of the Partnership Interests of all Partners at such time and make any adjustments necessary to reflect the difference, if any, between the fair market value of any Series A Preferred Units for which the Series A Conversion Date has not occurred and the aggregate Capital Accounts attributable to such Series A Preferred Units to the extent of any Unrealized Gain or Unrealized Loss that has not been reflected in the Partners’ Capital Accounts previously, consistent with the methodology of Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2), and then allocate such aggregate value among the individual properties of the Partnership (in such manner as it determines appropriate).

(ii)    In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), immediately prior to any actual or deemed distribution to a Partner of any Partnership property (other than a distribution of cash that is not in redemption or retirement of a Partnership Interest), the Carrying Value of all Partnership property shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property. In determining such Unrealized Gain or Unrealized Loss the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of an actual distribution that is not made pursuant to Section 12.4 or in the case of a deemed distribution, be determined in the same manner

as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4 , be determined by the Liquidator using such method of valuation as it may adopt.

(iii)    In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s), immediately after the conversion of a Series A Preferred Unit into Common Units in accordance with Section 5.14(b)(vi) , the Capital Account of each Partner and the Carrying Value of each Partnership property shall be adjusted to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately after such conversion and (A) first, all Unrealized Gain (if the Capital Account of each such Series A Conversion Unit is less than the Per Unit Capital Account for a then outstanding Initial Common Unit) or Unrealized Loss (if the Capital Account of each such Series A Conversion Unit is greater than the Per Unit Capital Account for a then outstanding Initial Common Unit) had been allocated to each Partner holding Series A Conversion Units received upon such conversion, Pro Rata, until the Capital Account of each such Series A Conversion Unit is equal to the Per Unit Capital Amount for a then outstanding Initial Common Unit; and (B) second, any remaining Unrealized Gain or Unrealized Loss had been allocated to the Partners at such time pursuant to Section 6.1(d) . In determining such Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership assets (including, without limitation, cash or cash equivalents) immediately after the conversion of a Series A Preferred Unit shall be determined by the General Partner using such reasonable method of valuation as it may adopt; provided , however , that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners at such time and must make such adjustments to such valuation as required by Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2). The General Partner shall allocate such aggregate value among the assets of the Partnership in such manner as it determines in its discretion to be reasonable. If, after making the allocations of Unrealized Gain and Unrealized Loss as set forth above in this Section 5.5(d)(iii) , the Capital Account of each Partner with respect to each Series A Conversion Unit received upon such conversion of the Series A Preferred Unit is different from the Per Unit Capital Amount for a then outstanding Initial Common Unit, then Capital Account balances shall be reallocated between the Partners holding Common Units (other than Series A Conversion Units) and Partners holding Series A Conversion Units so as to cause the Capital Account of each Partner holding a Series A Conversion Unit to equal, on a per Limited Partner Unit basis with respect to each such Series A Conversion Unit, the Per Unit Capital Amount for a then outstanding Initial Common Unit.

Section 5.6     Issuances of Additional Partnership Interests .

(a)    Subject to Section 5.12(b)(iv)(B) , Section 5.14(b)(iv) and Section 5.15(b)(ii)(C) , the Partnership may issue additional Partnership Interests (other than General Partner Interests) and Derivative Partnership Interests for any Partnership purpose at any time and from time to time to such Persons for such consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partners.

(b)    Each additional Partnership Interest authorized to be issued by the Partnership pursuant to Section 5.6(a) may be issued in one or more classes, or one or more series of any such classes, with such designations, preferences, rights, powers and duties (which may be senior to existing classes and series of Partnership Interests), as shall be fixed by the General Partner, including (i) the right to share in Partnership profits and losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem the Partnership Interest; (v) whether such Partnership Interest is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Partnership Interest will be issued, evidenced by Certificates and assigned or transferred; (vii) the method for determining the Percentage Interest as to such Partnership Interest; and (viii) the right, if any, of each such Partnership Interest to vote on Partnership matters, including matters relating to the relative rights, preferences and privileges of such Partnership Interest.

(c)    The General Partner shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of Partnership Interests and Derivative Partnership Interests pursuant to this Section 5.6 , (ii) the conversion of the Combined Interest into Limited Partner Units pursuant to the terms of this Agreement, (iii) reflecting admission of such additional Limited Partners in the Partnership Register as the Record Holders of such Limited Partner Interests and (iv) all additional issuances of Partnership Interests and Derivative Partnership Interests. The General Partner shall determine the relative rights, powers and duties of the holders of the Limited Partner Units

or other Partnership Interests or Derivative Partnership Interests being so issued. The General Partner shall do all things necessary to comply with the Delaware Act and is authorized and directed to do all things that it determines to be necessary or appropriate in connection with any future issuance of Partnership Interests or Derivative Partnership Interests or in connection with the conversion of the Combined Interest into Limited Partner Units pursuant to the terms of this Agreement, including compliance with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Limited Partner Units or other Partnership Interests are listed or admitted to trading.

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

Section 5.7    [Reserved.]

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

Section 5.9     Splits and Combinations .

(a)    Subject to Section 5.9(e) and Section 5.14(b)(vi)(E) , the Partnership may make a Pro Rata distribution of Partnership Interests to all Record Holders or may effect a subdivision or combination of Partnership Interests so long as, after any such event, each Partner shall have the same Percentage Interest in the Partnership as before such event, and any amounts calculated on a per Limited Partner Unit basis or stated as a number of Limited Partner Units (including the number of Common Units into which Series A Preferred Units may convert) are proportionately adjusted.

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

(c)    [Reserved.]

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

(e)    The Partnership shall not issue fractional Limited Partner Units upon any distribution, subdivision or combination of Limited Partner Units. If a distribution, subdivision or combination of Limited Partner Units would result in the issuance of fractional Limited Partner Units but for the provisions of Section 5.6(d) and this Section 5.9(e) , each fractional Limited Partner Unit shall be rounded to the nearest whole Limited Partner Unit (with fractional Limited Partner Units equal to or greater than a 0.5 Limited Partner Unit being rounded to the next higher Limited Partner Unit).

Section 5.10     Fully Paid and Non-Assessable Nature of Limited Partner Interests . All Limited Partner Interests issued pursuant to, and in accordance with the requirements of, this Article V shall be fully paid and non-assessable Limited Partner Interests in the Partnership, except as such non-assessability may be affected by Sections 17-303, 17-607 or 17-804 of the Delaware Act.

Section 5.11    [Reserved.]

Section 5.14     Establishment of Series A Preferred Units .

(a)     General . Pursuant to the Second Amended and Restated Partnership Agreement, there was created a class of Limited Partner Units designated as “Series A Convertible Preferred Units” (the “ Series A Preferred Units ”), with the designations, preferences and relative, participating, optional or other special rights, powers and duties as set forth in this Section 5.14 and elsewhere in this Agreement.

(b)     Rights of Series A Preferred Units . The Series A Preferred Units shall have the following rights, preferences and privileges and the Series A Preferred Unitholders shall be subject to the following duties and obligations:

(i)     Distributions .

(A)    Subject to Section 5.14(b)(i)(B) , commencing with the Quarter ending on June 30, 2016, subject to Section 5.14(b)(i)(D) , the Record Holders of the Series A Preferred Units as of the applicable Record Date for each Quarter shall be entitled to receive, in respect of each outstanding Series A Preferred Unit, cumulative distributions in respect of such Quarter equal to the sum of (1) the Series A Distribution Amount for such Quarter and (2) any Series A Unpaid Cash Distributions (collectively, a “ Series A Quarterly Distribution ”). Each Series A Quarterly Distribution shall be payable quarterly in cash within sixty (60) days after the end of the applicable Quarter (each such payment date, a “ Series A Distribution Payment Date ”). If the General Partner establishes an earlier Record Date for any distribution to be made by the Partnership on other Partnership Interests in respect of any Quarter, then the Record Date established pursuant to this Section 5.14(b)(i) for a Series A Quarterly Distribution in respect of such Quarter shall be the same Record Date. For the avoidance of doubt, subject to Section 5.14(b)(i)(D) , the Series A Preferred Units shall not be entitled to any distributions made pursuant to Section 6.3(a) for any Quarter so long as the Series A Quarterly Distribution has been declared and paid in accordance with this Section 5.14(b)(i) on the Series A Preferred Units with respect to such Quarter.

(B)    If the Partnership fails to pay in full the Series A Distribution Amount of any Series A Quarterly Distribution in cash when due for any Quarter, then from and after the first date of such failure and continuing until such failure is cured by payment in full in cash of all such arrearages, (1) the amount of such unpaid cash distributions (on a per Series A Preferred Unit basis, “ Series A Unpaid Cash Distributions ”) unless and until paid will accrue and accumulate from and including the first day of the Quarter immediately following the Quarter in respect of which such payment is due until paid in full and (2) the Partnership shall not be permitted to, and shall not, declare or make, any distributions, redemptions or repurchases in respect of any Series A Junior Securities or Series A Parity Securities (including, for the avoidance of doubt, with respect to the Quarter for which the Partnership first failed to pay in full the Series A Distribution Amount of any Series A Quarterly Distribution in cash when due); provided , however , that distributions may be declared and paid on the Series A Preferred Units and the Series A Parity Securities so long as such distributions are declared and paid pro rata so that amounts of distributions declared per Series A Preferred Unit and Series A Parity Security shall in all cases bear to each other the same ratio that accrued and accumulated distributions per Series A Preferred Unit and Series A Parity Security bear to each other.

(C)    The aggregate Series A Distribution Amount shall be paid out of Available Cash that is deemed to be Operating Surplus for the applicable Quarter. To the extent that any portion of a Series A Quarterly Distribution with respect to any Quarter exceeds the amount of Available Cash that is deemed to be Operating Surplus for such Quarter, the amount of cash equal to the Available Cash that is deemed to be Operating Surplus for such Quarter will be paid to the Series A Preferred Unitholders Pro Rata and the balance of such Series A Quarterly Distribution shall be unpaid and shall constitute an arrearage and shall accrue and accumulate as set forth in Section 5.14(b)(i)(B) .

(D)    Notwithstanding anything in this Section 5.14(b)(i) to the contrary, with respect to any Series A Preferred Unit that is converted into a Common Unit, the Record Holder thereof shall not be entitled to a distribution in respect of such Series A Preferred Unit and a distribution in respect of such Common Unit with respect to the same period, but shall be entitled only to the distribution to be paid based upon the class of Limited Partner Units held as of the close of business on the applicable Record Date. For the avoidance of doubt, if a Series A Conversion Date occurs prior to the close of business on a Record Date for payment of a distribution on the Common Units, the applicable Record Holder of Series A Preferred Units shall receive, with respect to any Series A Preferred

Units that have converted into Common Units, only the distribution in respect of such Common Units with respect to such period.

(ii)     Issuance of the Series A Preferred Units . Subject to Section 5.14(b)(iv) , the Series A Preferred Units shall be issued by the Partnership pursuant to the terms and conditions of the Series A Purchase Agreement.

(iii)     Voting Rights .

(A)    Except as provided in Section 5.14(b)(iii)(B) , the Voting Eligible Series A Preferred Units shall have voting rights that are identical to the voting rights of the Common Units and shall vote with the Common Units as a single class, so that each Voting Eligible Series A Preferred Unit will be entitled to one vote for each Common Unit into which such Series A Preferred Unit would be convertible at the then applicable Series A Conversion Rate (regardless of whether the Series A Preferred Units are then convertible) on each matter with respect to which each Record Holder of a Common Unit is entitled to vote. Each reference in this Agreement to a vote of Record Holders of Common Units shall be deemed to be a reference to the Record Holders of Common Units and Series A Preferred Units, voting together as a single class during any period in which any Series A Preferred Units are outstanding.

(B)    Notwithstanding any other provision of this Agreement, in addition to all other requirements imposed by Delaware law, and all other voting rights granted under this Agreement, the affirmative vote of the Record Holders of the Series A Required Voting Percentage shall be required for any amendment to this Agreement or the Certificate of Limited Partnership (including by merger or otherwise or any amendment contemplated by and made in accordance with Section 5.14(b)(iv) ) that is materially adverse to any of the rights, preferences and privileges of the Series A Preferred Units. Without limiting the generality of the preceding sentence, any amendment shall be deemed to have such a material adverse impact if such amendment would:

(1)    Reduce the Series A Distribution Amount, change the form of payment of distributions on the Series A Preferred Units, defer the date from which distributions on the Series A Preferred Units will accrue, cancel accrued and unpaid distributions on the Series A Preferred Units, or change the seniority rights of the Series A Preferred Unitholders as to the payment of distributions in relation to the holders of any other class or series of Partnership Interests;

(2)    Reduce the amount payable or change the form of payment to the Record Holders of the Series A Preferred Units upon the voluntary or involuntary liquidation, dissolution or winding up, or sale of all or substantially all of the assets, of the Partnership, or change the seniority of the liquidation preferences of the Record Holders of the Series A Preferred Units in relation to the rights upon liquidation of the holders of any other class or series of Partnership Interests; or

(3)    Make the Series A Preferred Units redeemable or convertible at the option of the Partnership other than as set forth herein.

(C)    Notwithstanding anything to the contrary in this Section 5.14(b)(iii) , in no event shall the consent of the Series A Preferred Unitholders, as a separate class, be required in connection with any Series A Change of Control or Partnership Restructuring Event. For the avoidance of doubt, the foregoing shall not limit the voting rights of any Series A Preferred Unitholder in connection with the vote of Record Holders of Common Units and Series A Preferred Units together as a single class.

(D)    Notwithstanding any other provision of this Agreement, in addition to all other voting rights granted under this Agreement, the Partnership shall not declare or pay any distribution from Capital Surplus without the affirmative vote of the Record Holders of the Series A Required Voting Percentage.

(iv)     No Series A Senior Securities; Series A Parity Securities . Other than issuances contemplated by the Series A Purchase Agreement, the Partnership shall not, without the affirmative vote of the Record Holders of the Series A Required Voting Percentage, issue any (A) Series A Senior Securities (or amend the provisions of any class of Partnership Interests to make such class of Partnership Interests a class of Series A Senior Securities) or (B) Series A Parity Securities (or amend the provisions of any class of Partnership Interests to make

such class of Partnership Interests a class of Series A Parity Securities) or Series A Preferred Units; provided that, without the consent of the holders of Voting Eligible Series A Preferred Units (but without prejudice to their rights under Section 5.14(b)(iii)(A) ), the Partnership may issue (1) at any time in the aggregate, up to the greater of (a) an aggregate $500,000,000 of Series A Parity Securities and (b) a number of Series A Parity Securities such that, as of the date of the issuance of the Series A Parity Securities, the aggregate number of Series A Parity Securities, together with the Series A Preferred Units, in each case on an “ as if ” converted basis (or, if the Series A Parity Securities are not convertible, assuming that such Series A Parity Securities are convertible into a number of Common Units equal to the quotient of (i) the aggregate purchase price for such Series A Parity Securities, divided by (ii) the volume-weighted average price of the Common Units for the twenty (20) Trading Day period ending immediately prior to such issuance (such Common Units, the “ Series A Parity Equivalent Units ”)), equals no more than 15% of all outstanding Common Units (including as outstanding for such purposes, (i) any Common Units issuable in respect of the Series A Preferred Units at the then applicable Series A Conversion Rate (regardless of whether the Series A Preferred Units are then convertible), (ii) any Common Units issuable in respect of Series A Parity Securities (including any warrants issued in connection with Series A Parity Securities) at the initial or then applicable conversion rate, as applicable, and (iii) any Series A Parity Equivalent Units), and (2) if a number of Series A Preferred Units having an aggregate Series A Issue Price of less than $500,000,000 is then outstanding, such number of Series A Parity Securities as determined by the General Partner. Subject to Section 5.14(b)(vi)(E) , the Partnership may, without any vote of the holders of Voting Eligible Series A Preferred Units (but without prejudice to their rights under Section 5.14(b)(iii)(A) ), create (by reclassification or otherwise) and issue Series A Junior Securities in an unlimited amount.

(v)    [Reserved]

(vi)     Conversion .

(A)     At the Option of the Series A Preferred Unitholders . Beginning with the earlier of (i) the third anniversary of the Series A Issuance Date, and (ii) immediately prior to the liquidation, dissolution and winding up of the Partnership under Section 12.4 , the Series A Preferred Units owned by any Series A Preferred Unitholder shall be convertible, in whole or in part, at any time and from time to time upon the request of such Series A Preferred Unitholder, but not more than once per Quarter by such Series A Preferred Unitholder (inclusive of any conversion by such Series A Preferred Unitholder’s Affiliates, with each Series A Preferred Unitholder and its Affiliates being entitled to a single conversion right per Quarter), into a number of Common Units determined by multiplying the number of Series A Preferred Units to be converted by the Series A Conversion Rate at such time; provided , however , that the Partnership shall not be obligated to honor any such conversion request if such conversion request does not involve an underlying value of Common Units of at least $100,000,000 (taking into account any concurrent conversion requests by any Affiliates of such Series A Preferred Unitholder) based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A Conversion Notice Date (or a lesser amount to the extent such exercise covers all of such Series A Preferred Unitholder’s Series A Preferred Units). Immediately upon the issuance of Common Units as a result of any conversion of Series A Preferred Units, all rights of the Series A Converting Unitholder with respect to such Series A Preferred Units shall cease, including any further accrual of distributions, and such Series A Converting Unitholder thereafter shall be treated for all purposes as the owner of Common Units. Fractional Common Units shall not be issued to any Person pursuant to this Section 5.14(b)(vi)(A) (each fractional Common Unit shall be rounded down with the remainder being paid an amount in cash based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A Conversion Notice Date).

(B)     At the Option of the Partnership . At any time following the fourth anniversary of the Series A Issuance Date, the Partnership shall have the option at any time, but not more than once per Quarter, to convert all or any portion of the Series A Preferred Units then outstanding into a number of Common Units determined by multiplying the number of Series A Preferred Units to be converted by the Series A Conversion Rate. Fractional Common Units shall not be issued to any Person pursuant to this Section 5.14(b)(vi)(B) (each fractional Common Unit shall be rounded down with the remainder being paid an amount in cash based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A Forced Conversion Notice Date). Notwithstanding the foregoing, in order for the Partnership to exercise such option:

(1)    The Closing Price of the Common Units must be equal to or greater than one hundred fifty percent (150%) of the Series A Issue Price for the 20 Trading Day period immediately preceding the Series A Forced Conversion Notice Date;

(2)    The average daily trading volume of the Common Units on the National Securities Exchange on which the Common Units are then listed or admitted to trading must be equal to or exceed 1,000,000 (as such amount may be adjusted to reflect any Limited Partner Unit split, combination or similar event) for the 20 Trading Day period immediately preceding the Series A Forced Conversion Notice Date; and

(3)    The Partnership must have an effective registration statement on file with the Commission covering resales of the underlying Common Units to be received upon any such conversion, and

provided , that each such conversion by the Partnership shall be for an aggregate amount of Series A Preferred Units involving an underlying value of Common Units of at least $100,000,000 based on the Closing Price of Common Units on the Trading Day immediately preceding the Series A Forced Conversion Notice Date (or a lesser amount if such amount includes all then outstanding Series A Preferred Units) and shall be allocated among the Series A Preferred Unitholders on a Pro Rata basis or on such other basis as may be agreed upon by all Series A Preferred Unitholders.

(C)     Conversion Notice .

(1)    To convert Series A Preferred Units into Common Units pursuant to Section 5.14(b)(vi)(A) , a Series A Converting Unitholder shall give written notice (a “ Series A Conversion Notice ,” and the date such notice is received, a “ Series A Conversion Notice Date ”) to the Partnership stating that such Series A Preferred Unitholder elects to so convert Series A Preferred Units pursuant to Section 5.14(b)(vi)(A) and the number of Series A Preferred Units to be converted.

(2)    To convert Series A Preferred Units into Common Units pursuant to Section 5.14(b)(vi)(B) , the Partnership shall give written notice (a “ Series A Forced Conversion Notice ,” and the date such notice is received, a “ Series A Forced Conversion Notice Date ”) to each Record Holder of Series A Preferred Units stating that the Partnership elects to force conversion of Series A Preferred Units pursuant to Section 5.14(b)(vi)(B) and the number of Series A Preferred Units to be so converted. The Series A Conversion Units shall be issued in the name of the Record Holder of such Series A Preferred Units.

(D)     Timing . If a Series A Conversion Notice is delivered by a Series A Preferred Unitholder to the Partnership or a Series A Forced Conversion Notice is delivered by the Partnership to a Series A Preferred Unitholder, each in accordance with Section 5.14(b)(vi)(C) , the Partnership shall issue the applicable Series A Conversion Units no later than three (3) Business Days after the Series A Conversion Notice Date or the Series A Forced Conversion Notice Date, as the case may be, occurs (any date of issuance of such Common Units, and any date of issuance of Common Units upon conversion of Series A Preferred Units pursuant to Section 5.14(b)(vi)(G) or Section 5.14(b)(vii) , a “ Series A Conversion Date ”). On the Series A Conversion Date, the Partnership shall instruct, and shall use its commercially reasonable efforts to cause, its Transfer Agent to electronically transmit the Series A Conversion Units issuable upon conversion to such Series A Preferred Unitholder (or designated recipient(s)), by crediting the account of the Series A Preferred Unitholder (or designated recipient(s)) prime broker with the Depository through its Deposit Withdrawal Agent Commission system. The parties agree to coordinate with the Depository to accomplish this objective. Upon issuance of Series A Conversion Units to the Series A Converting Unitholder, all rights under the converted Series A Preferred Units shall cease, and such Series A Converting Unitholder shall be treated for all purposes as the Record Holder of such Series A Conversion Units.

(E)     Distributions, Combinations, Subdivisions and Reclassifications by the Partnership . If, after the Series A Issuance Date, the Partnership (i) makes a distribution on its Common Units payable in Common Units or another Partnership Interest, (ii) subdivides or splits its outstanding Common Units into a greater number of Common Units, (iii) combines or reclassifies its Common Units into a lesser number of Common Units, (iv) issues by reclassification of its Common Units any Partnership Interests (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person), (v) effects a Pro Rata repurchase of Common Units, in each case other than in connection with a Series A Change of Control (which shall be governed by Section 5.14(b)(vii) ), (vi) issues to Common Unitholders, in their capacity as

Common Unitholders rights, options or warrants entitling them to subscribe for or purchase Common Units at less than the market value thereof, (vii) distributes to Common Unitholders evidences of indebtedness, Partnership Interests (other than Common Units) or other assets (including securities, but excluding any distribution referred to in clause (i), any rights or warrants referred to in clause (ii), any consideration payable in connection with a tender or exchange offer made by the Partnership or any of its subsidiaries and any distribution of Limited Partner Units or any class or series, or similar Partnership Interest, of or relating to a subsidiary or other business unit in the case of certain spin-off transactions described below), or (viii) consummates a spin-off, where the Partnership makes a distribution to all Common Unitholders consisting of Limited Partner Units of any class or series, or similar equity interests of, or relating to, a subsidiary or other business unit, then the Series A Conversion Rate, the Series A Conversion Floor Trigger and, solely for purposes of Section 5.14(b)(vi)(B)(1) , the Series A Issue Price, in each case, in effect at the time of the Record Date for such distribution or the effective date of any such other transaction shall be proportionately adjusted: (1) in respect of clauses ( i ) through ( iv ) above, so that the conversion of the Series A Preferred Units after such time shall entitle each Series A Preferred Unitholder to receive the aggregate number of Common Units (or any Partnership Interests into which such Common Units would have been combined, consolidated, merged or reclassified, as applicable) that such Series A Preferred Unitholder would have been entitled to receive if the Series A Preferred Units had been converted into Common Units immediately prior to such Record Date or effective date, as the case may be, (2) in respect of clauses ( v ) through ( viii ) above, in the reasonable discretion of the General Partner to appropriately ensure that the Series A Preferred Units are convertible into an economically equivalent number of Common Units after taking into account the event described in clauses ( vi ) through ( viii ) above, and (3) in addition to the foregoing, in the case of a merger, consolidation or business combination in which the Partnership is the surviving Person, the Partnership shall provide effective provisions to ensure that the provisions in this Section 5.14 relating to the Series A Preferred Units shall not be abridged or amended and that the Series A Preferred Units shall thereafter retain the same powers, economic rights, preferences and relative participating, optional and other special rights, and the qualifications, limitations and restrictions thereon, that the Series A Preferred Units had immediately prior to such transaction or event, and, solely for purposes of Section 5.14(b)(vi)(B)(1) , the Series A Issue Price, and any other terms of the Series A Preferred Units that the General Partner in its reasonable discretion determines require adjustment to achieve the economic equivalence described below, shall be proportionately adjusted to take into account any such subdivision, split, combination or reclassification. An adjustment made pursuant to this Section 5.14(b)(vi)(E) shall become effective immediately after the Record Date in the case of a distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person) or split. Such adjustment shall be made successively whenever any event described above shall occur.

(F)     No Adjustments for Certain Items . Notwithstanding any of the other provisions of this Section 5.14(b)(vi) , no adjustment shall be made to the Series A Conversion Rate, the Series A Conversion Floor Trigger or the Series A Issue Price pursuant to Section 5.14(b)(vi)(E) as a result of any of the following:

(1)    Any issuance of Partnership Interests in exchange for cash;

(2)    Any grant of Common Units or options, warrants or rights to purchase or receive Common Units or the issuance of Common Units upon the exercise or vesting of any such options, warrants or rights in respect of services provided to or for the benefit of the Partnership or its Subsidiaries, under compensation plans and agreements approved by the General Partner (including any long-term incentive plan);

(3)    Any issuance of Common Units as all or part of the consideration to effect (i) the closing of any acquisition by the Partnership of assets or equity interests of a third party in an arm’s-length transaction, (ii) closing of any acquisition by the Partnership of assets or equity interests of MPC or any of its Affiliates or (iii) the consummation of a merger, consolidation or other business combination of the Partnership with another entity in which the Partnership survives and the Common Units remain outstanding to the extent any such transaction set forth in clause ( i ), ( ii ) or ( iii ) above is validly approved by the General Partner; or

(4)    The issuance of Common Units upon conversion of the Series A Preferred Units or Series A Parity Securities.

Notwithstanding anything in this Agreement to the contrary, whenever the issuance of a Partnership Interest or other event would require an adjustment to the Series A Conversion Rate under one or more provisions of this Agreement, only one adjustment shall be made to the Series A Conversion Rate in respect of such issuance or event.

Notwithstanding anything to the contrary in Section 5.14(b)(vi)(E) , unless otherwise determined by the General Partner, no adjustment to the Series A Conversion Rate, Series A Conversion Floor Trigger or the Series A Issue Price shall be made with respect to any distribution or other transaction described in Section 5.14(b)(vi)(E) if the Series A Preferred Unitholders are entitled to participate in such distribution or transaction as if they held a number of Common Units issuable upon conversion of the Series A Preferred Units immediately prior to such event at the then applicable Series A Conversion Rate, without having to convert their Series A Preferred Units.

(G)    Notwithstanding anything to the contrary in Section 5.14(b)(vii) or elsewhere in this Agreement, in connection with any transaction pursuant to which MPC or any of its Affiliates (other than the Partnership or any of its Subsidiaries) would acquire, (x) all of the Partnership’s outstanding Common Units or (y) all or substantially all of the assets of the Partnership and its Subsidiaries, in each case including by way of merger, consolidation, or otherwise (including any such transaction undertaken pursuant to Section 15.1 ), then the Partnership shall have the right, by delivering written notice to the Record Holders of the Series A Preferred Units, to convert all, but not less than all, of the Series A Preferred Units into Common Units at the Series A COC Conversion Rate effective immediately prior to the consummation of such transaction.

(vii)     Series A Change of Control .

(A)    Subject to Section 5.14(b)(vi)(B) , in the event of a Series A Cash COC Event, the outstanding Series A Preferred Units shall be automatically converted, without requirement of any action of the Series A Preferred Unitholders, into Common Units immediately prior to the closing of the Series A Cash COC Event at the Series A COC Conversion Rate.

(B)    Subject to Section 5.14(b)(vi)(B) and Section 5.14(b)(vi)(G) , at least ten (10) Business Days prior to consummating a Series A Change of Control (other than a Series A Cash COC Event), the Partnership shall provide written notice thereof to the Series A Preferred Unitholders. Subject to Section 5.14(b)(vi)(B) , if a Series A Change of Control (other than a Series A Cash COC Event) occurs, then each Series A Preferred Unitholder, with respect to all but not less than all of its Series A Preferred Units, by notice given to the Partnership within five (5) Business Days of the date the Partnership provides written notice of the execution of definitive agreements that provide for such Series A Change of Control, shall be entitled to elect one of the following (with the understanding that any Series A Preferred Unitholder who fails to timely provide notice of its election to the Partnership shall be deemed to have elected the option set forth in sub-clause ( 1 ) below):

(1)    Convert all, but not less than all, of such Series A Preferred Unitholder’s outstanding Series A Preferred Units into Common Units, at the then-applicable Series A Conversion Rate;

(2)    If the Partnership will not be the surviving entity of such Series A Change of Control or the Partnership will be the surviving entity but its Common Units will cease to be listed or admitted to trading on a National Securities Exchange, require the Partnership to use its commercially reasonable efforts to deliver or to cause to be delivered to the Series A Preferred Unitholders, in exchange for their Series A Preferred Units upon such Series A Change of Control, a security in the surviving entity or the parent of the surviving entity that has substantially similar rights, preferences and privileges as the Series A Preferred Units, including, for the avoidance of doubt, the right to distributions equal in amount and timing to those provided in Section 5.14(b)(i) and a conversion rate proportionately adjusted such that the conversion of such security in the surviving entity or parent of the surviving entity immediately following the Series A Change of Control would entitle the Record Holder to the number of common securities of such entity (together with a number of common securities of equivalent value to any other assets received by Common Unitholders in such Series A Change of Control) which, if a Series A Preferred Unit had been converted into Common Units immediately prior to such Series A Change of Control, such Record Holder would have been entitled to receive immediately following such Series A Change of Control (such security in the surviving entity, a “ Series A Substantially Equivalent Unit ”); provided , however , that, if the Partnership is unable to deliver or cause to be delivered Series A Substantially Equivalent Units to any Series A Preferred Unitholder in connection with such Series A Change of Control, each Series A Preferred Unitholder shall

be entitled to (I) require conversion or redemption of such Series A Preferred Units in the manner contemplated by sub-clause ( 1 ) or ( 4 ) of this Section 5.14(b)(vii)(B) (at such holder’s election) or (II) convert the Series A Preferred Units held by such Series A Preferred Unitholder immediately prior to such Series A Change of Control into a number of Common Units at a conversion ratio equal to the quotient of: (a) the product of (i) 160% multiplied by (ii) the Series A Issue Price less the Series A Preferred Unitholder’s Pro Rata portion of the sum of all cash distributions paid on all Series A Preferred Units on or prior to the date of the Series A Change of Control, divided by (b) an amount equal to 95% of the volume-weighted average price of the Common Units for the 30 Trading Day period prior to the closing of the Series A Change of Control; provided that such ratio shall in no event exceed a value per Series A Preferred Unit equal to (i) 120% of the Series A Issue Price in the case of a Series A Change of Control occurring on or prior to the first anniversary of the Series A Issuance Date, (ii) 130% of the Series A Issue Price in the case of a Series A Change of Control occurring after the first anniversary of the Series A Issuance Date but on or prior to the second anniversary of the Series A Issuance Date, and (iii) 140% of the Series A Issue Price in the case of a Series A Change of Control occurring after the second anniversary of the Series A Issuance Date but on or prior to the third anniversary of the Series A Issuance Date.

(3)    If the Partnership is the surviving entity of such Series A Change of Control, continue to hold Series A Preferred Units; or

(4)    Require the Partnership to redeem the Series A Preferred Units at a price per Series A Preferred Unit equal to 101% of the Series A Issue Price plus (x) Series A Unpaid Cash Distributions on the applicable Series A Preferred Unit and (y) Series A Partial Period Distributions on the applicable Series A Preferred Unit. Any redemption pursuant to this sub-clause (4) shall, as determined by the General Partner, be paid in cash and/or Common Units. If all or any portion of such redemption is to be paid in Common Units, the Common Units to be issued shall be valued at 95% of the volume-weighted average price of the Common Units for the 30 Trading Day period ending on the fifth Trading Day immediately prior to the Series A Change of Control. No later than three Trading Days prior to the consummation of the related Series A Change of Control, the Partnership shall deliver a written notice to the Record Holders of the Series A Preferred Units stating the date on which the Series A Preferred Units will be redeemed and the Partnership’s computation of the amount of cash or Common Units to be received by the Record Holder upon redemption of such Series A Preferred Units. If the Partnership shall be the surviving entity of the related Series A Change of Control, then no later than 10 Business Days following the consummation of such Series A Change of Control, the Partnership shall remit the applicable cash or Common Unit consideration to the Record Holders of then outstanding Series A Preferred Units. If the Partnership shall not be the surviving entity of the related Series A Change of Control, then the Partnership shall remit the applicable cash or Common Unit immediately prior to the consummation of the Series A Change of Control. The Record Holders shall deliver to the Partnership any Certificates representing the Series A Preferred Units as soon as practicable following the redemption. Record Holders of the Series A Preferred Units shall retain all of the rights and privileges thereof unless and until the consideration due to them as a result of such redemption shall be paid in full in cash or Common Units, as applicable. After any such redemption, any such redeemed Series A Preferred Unit shall no longer constitute an issued and outstanding Limited Partner Interest.

(viii)     Series A Preferred Unit Transfer Restrictions .

(A)    Notwithstanding any other provision of this Section 5.14(b)(viii) , each Series A Preferred Unitholder shall be permitted to transfer any Series A Preferred Units owned by such Series A Preferred Unitholder to any of its Affiliates or to any other Series A Preferred Unitholder.

(B)    Without the prior written consent of the Partnership, except as specifically provided in this Agreement and the Series A Purchase Agreement, each Series A Preferred Unitholder shall not, (a) during the period commencing on the Series A Issuance Date and ending on the first anniversary of the Series A Issuance Date, offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any of its Series A Preferred Units, (b) during the period commencing on the Series A Issuance Date and ending on the second anniversary of the Series A Issuance Date, directly or indirectly engage in any short sales or other derivative or hedging transactions with respect to the Series A Preferred Units that are designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of any Series A Preferred Units, (c) transfer any Series A Preferred Units to any non-U.S. resident individual, non-U.S.

corporation or partnership, or any other non-U.S. entity, including any foreign governmental entity, including by means of any swap or other transaction or arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of any Series A Preferred Units, regardless of whether any transaction described in clauses (a) through (c) above is to be settled by delivery of Series A Preferred Units, Common Units or other securities, in cash or otherwise, or (d) effect any transfer of Series A Preferred Units or Series A Conversion Units in a manner that violates the terms of this Agreement; provided , however , that such Series A Preferred Unitholder may pledge all or any portion of its Series A Preferred Units to any holders of obligations owed by the Series A Preferred Unitholders, including to the trustee for, or representative of, such holders. Notwithstanding the foregoing, any transferee receiving any Series A Preferred Units pursuant to this Section 5.14(b)(viii)(B) shall agree to the restrictions set forth in this Section 5.14(b)(viii)(B) .

(C)    Following the first anniversary of the Series A Issuance Date, the Series A Purchasers or their permitted transferees may freely transfer Series A Preferred Units involving an underlying value of Common Units of at least $50,000,000 (taking into account any concurrent transfers by Affiliates of such Series A Preferred Unitholder) based on the Series A Issue Price (or such lesser amount if it (i) constitutes the remaining holdings of such Series A Preferred Unitholder or (ii) has been approved by the General Partner), subject to compliance with applicable securities laws and this Agreement, including sub-clauses ( b ) and ( c ) of Section 5.14(b)(viii)(B) .

(D)    Notwithstanding anything to the contrary in subclause (a) of Section 5.14(b)(viii)(B) , but subject to compliance with applicable securities laws and this Agreement, including subclauses (b) and (c) of Section 5.14(b)(viii)(B) , during the period beginning on the Series A Issuance Date and ending on the date that is 60 days after the Series A Issuance Date (the “ Non-Affiliate Transfer Period ”), Stonepeak and its Affiliates may transfer or dispose of Series A Preferred Units to one or more non-Affiliates of Stonepeak, subject to the consent of the Partnership as to the identity of the transferee (which consent shall not be unreasonably withheld, conditioned or delayed); provided , however , that (A) any transfer made pursuant to this sentence must consist of Series A Preferred Units in an amount not less than $25 million based on the Series A Issue Price, (B) the aggregate amount of Series A Preferred Units and rights to purchase Series A Preferred Units transferred pursuant to this Section 5.14(b)(viii)(D) and Section 8.10 of the Series A Purchase Agreement shall not be greater than $100 million based on the Series A Issue Price and (C) a maximum of two transfers may be made pursuant to this Section 5.14(b)(viii)(D) and Section 8.10 of the Series A Purchase Agreement.

(ix)     Fully Paid and Non-Assessable . Any Series A Conversion Unit(s) delivered pursuant to this Section 5.14 shall be validly issued, fully paid and non-assessable (except as such non-assessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware Act), free and clear of any liens, claims, rights or encumbrances other than those arising under the Delaware Act or this Agreement or created by the holders thereof.

(x)     Notices . For the avoidance of doubt, the Partnership shall distribute to the Record Holders of Series A Preferred Units copies of all notices, materials, annual and quarterly reports, proxy statements, information statements and any other documents distributed generally to the Record Holders of Common Units of the Partnership, at such times and by such method as such documents are distributed to such Record Holders of such Common Units.

Section 5.15     Establishment of Series B Preferred Units .

(a)     General . The General Partner hereby designates and creates a class of Limited Partner Units designated as Series B Perpetual Preferred Units (the “ Series B Preferred Units ”) having only the designations, rights, preferences and privileges and shall be subject to the following duties and obligations as set forth herein, including this Section 5.15. Each Series B Preferred Unit shall be identical in all respects to every other Series B Preferred Unit, except as to the dates from which Series B Distributions may begin accruing, to the extent such dates may differ. The Series B Preferred Units represent perpetual equity interests in the Partnership and, except as set forth in Section 5.15(b)(iii) , shall not give rise to a claim by the Partnership or a Series B Preferred Unitholder for redemption or the conversion thereof, as applicable, at a particular date. The authorized number of Series B Preferred Units shall be unlimited. In accordance with Section 5.6, and subject to Section 5.14(b)(iv) and Section 5.12(b)(iv)(B) , the General Partner shall have the power and authority to issue additional Series B Preferred Units in the future.

(b)     Rights of Series B Preferred Units . The Series B Preferred Units shall have the following designations, rights, preferences and privileges and the Series B Preferred Unitholders shall be subject to the following duties and obligations:

(i)     Distributions .

(A)    Except for the Series B Initial Distribution which shall be payable on the Series B Initial Distribution Date, each Series B Distribution shall accrue and be cumulative at the applicable Series B Distribution Rate from and including the Series B Original Issue Date (or, for any subsequently issued and newly outstanding Series B Preferred Units, from and including the Series B Distribution Payment Date immediately preceding the issue date of such Series B Preferred Units) until such time as the Partnership pays the Series B Distribution or redeems such Series B Preferred Unit in accordance with Section 5.15(b)(iii) , whether or not such Series B Distributions shall have been declared. Series B Preferred Unitholders shall be entitled to receive Series B Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series B Distribution Rate per Series B Preferred Unit when, as, and if declared by the General Partner. Series B Distributions, to the extent declared by the General Partner to be paid by the Partnership, shall accumulate in each Series B Distribution Period from and including the preceding Series B Distribution Payment Date or the Series B Original Issue Date, as the case may be, to but excluding the applicable Series B Distribution Payment Date for such period, and Series B Distributions shall accrue on accumulated Series B Distributions at the Series B Distribution Rate. If any Series B Distribution Payment Date otherwise would fall on a day that is not a Business Day, declared Series B Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional Series B Distributions. During the Series B Fixed Rate Period, Series B Distributions on the Series B Preferred Units shall be payable based on a 360-day year consisting of twelve 30-day months. During the Series B Floating Rate Period, Series B Distributions on the Series B Preferred Units shall be computed by multiplying the floating rate for that Series B Distribution Period by a fraction, the numerator of which shall be the actual number of days elapsed during that Series B Distribution Period (determined by including the first day of the Series B Distribution Period and excluding the last day, which is the Series B Distribution Payment Date), and the denominator of which shall be 360, and by multiplying the result by the aggregate Series B Liquidation Preference of the Series B Preferred Units. All Series B Distributions payable by the Partnership pursuant to this Section 5.15(b)(i) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code.

(B)    Not later than 5:00 p.m., New York City time, on each Series B Distribution Payment Date, the Partnership shall pay those Series B Distributions, if any, that shall have been declared by the General Partner to each Series B Preferred Unitholder on the Record Date for the applicable Series B Distribution. So long as the Series B Preferred Units are held of record by the nominee of the Depository, declared Series B Distributions shall be paid to the Depository in same-day funds on each Series B Distribution Payment Date. The Depository shall credit accounts of its participants in accordance with the Depository’s normal procedures. The participants shall be responsible for holding or disbursing such payments to beneficial owners of the Series B Preferred Units in accordance with the instructions of such beneficial owners. If the Partnership fails to pay in full the Series B Distributions in cash when due on any Series B Distribution Payment Date, then from and after the first date of such failure and continuing until such failure is cured by payment in full in cash of all such arrearages, (1) the amount of such unpaid cash distributions (on a per Series B Preferred Unit basis, “ Series B Unpaid Cash Distributions ”) unless and until paid will accrue and accumulate from and including the first day of such failure until paid in full and (2) the Partnership shall not be permitted to, and shall not, declare or make, any distributions, redemptions or repurchases in respect of any Series B Junior Securities or Series B Parity Securities (including, for the avoidance of doubt, with respect to the Series B Distribution Period for which the Partnership first failed to pay in full the Series B Distributions in cash when due); provided, however, that distributions may be declared and paid on the Series B Preferred Units and the Series B Parity Securities so long as such distributions are declared and paid Pro Rata so that amounts of distributions declared per Series B Preferred Unit and Series B Parity Security shall in all cases bear to each other the same ratio that accrued and accumulated distributions per Series B Preferred Unit and Series A Parity Security bear to each other. To the extent a distribution period applicable to a class of Series B Junior Securities or Series B Parity Securities is shorter than the Series B Distribution Period applicable to the Series B Preferred Units, the General Partner may declare and pay regular distributions with respect to such Series B Junior Securities or Series B Parity Securities; provided that, at the time of declaration of such distribution, the General Partner expects to have sufficient

funds to pay the full Series B Distribution in respect of such Series B Preferred Units on the next successive Series B Distribution Payment Date.

(C)    The “Series B Three-Month LIBOR” for each Series B Distribution Period during the Series B Floating Rate Period shall be determined by the Calculation Agent, as of the applicable Series B LIBOR Determination Date, in accordance with the following provisions:

(1)    The Series B Three-Month LIBOR shall be the rate (expressed as a percentage per year) for deposits in U.S. dollars for a three-month period commencing on the first day of such Series B Distribution Period that appears on Reuters Page LIBOR01 as of 11:00 a.m. (London time) on the Series B LIBOR Determination Date.

(2)    If the Calculation Agent determines that the Series B Three-Month LIBOR has been discontinued, then the Calculation Agent shall determine whether to use a substitute or successor base rate that the Calculation Agent has determined in its sole discretion is most comparable to the Series B Three-Month LIBOR; provided that if the Calculation Agent determines there is an industry-accepted successor base rate, the Calculation Agent shall use such successor base rate. If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may implement changes to the Business Day convention, the definition of “business day” and the “determination date” in a manner that is consistent with industry-accepted practices for such substitute or successor base rate.

(3)    If the Series B Three-Month LIBOR cannot be determined as described in Section 5.15(b)(i)(C)(1) and the Calculation Agent does not make a determination under Section 5.15(b)(i)(C)(2) , then the Series B Three-Month LIBOR shall be determined on the basis of the rates, at approximately 11:00 a.m. (London time) on the second London Business Day immediately preceding the first day of such Series B Distribution Period, at which deposits of the following kind are offered to prime banks in the London interbank market by four major banks in that market selected by the Calculation Agent: three-month deposits in U.S. dollars, beginning on the first day of the Series B Distribution Period in a Representative Amount. The Calculation Agent shall request the principal London office of each of these banks to provide a quotation of its rate. If at least two quotations are provided, the Series B Three-Month LIBOR for the second London Business Day immediately preceding the first day of such Series B Distribution Period shall be the arithmetic mean of the quotations. If fewer than two of the requested quotations are provided, the Series B Three-Month LIBOR for the Series B LIBOR Determination Date shall be the arithmetic mean of the rates for loans of the following kind to leading European banks quoted, at approximately 11:00 a.m. (New York City time), on the second London Business Day immediately preceding the first day of such Series B Distribution Period, by major banks in New York City selected by the Calculation Agent: three-month loans of U.S. dollars, beginning on the first day of such interest period and in a Representative Amount. If no quotation is provided, then the Calculation Agent, after consulting such sources as it deems comparable to any of the foregoing quotations or display page, or any such source as it deems reasonable from which to estimate the Series B Three-Month LIBOR or any of the foregoing lending rates, shall determine the Series B Three-Month LIBOR for the second London Business Day immediately preceding the first day of such Series B Distribution Period in its sole discretion.

(4)    All percentages resulting from any of the above calculations shall be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards and all dollar amounts used in or resulting from such calculations shall be rounded to the nearest cent (with one-half cent being rounded upwards).

(ii)     Voting Rights .

(A)    Notwithstanding anything to the contrary in this Agreement, the Series B Preferred Units shall not have any voting rights except as set forth in this Section 5.15(b)(ii) or as otherwise required by the Delaware Act.

(B)    Without the affirmative vote or consent of holders of at least 66 2/3% of the Voting Eligible Series B Preferred Units (excluding any Voting Eligible Series B Preferred Units held by the General Partner or any of its Affiliates), voting as a single separate class, the General Partner shall not adopt any amendment to this Agreement that would have a material adverse effect on the preferences, rights, powers, duties or obligations of the Series B Preferred Units; provided, however , that:

(1)    subject to Section 5.15(b)(ii)(C) , any amendment solely relating to the issuance of additional Partnership Interests shall not be deemed to constitute a material adverse effect on the preferences, powers, qualifications, limitations, restrictions and special or relative rights or privileges of the Series B Preferred Units for purposes of this Section 5.15(b)(ii)(B) ; and

(2)    for purposes of this Section 5.15(b)(ii)(B) , no amendment of this Agreement in connection with a merger or other transaction in which the Partnership is the surviving entity and the Series B Preferred Units remain outstanding with the terms thereof materially unchanged in any respect adverse to the Series B Preferred Unitholders shall be deemed to materially and adversely affect the powers, preferences, duties or special rights of the Series B Preferred Units.

(C)    Without the affirmative vote or consent of the Record Holders of at least 66 2/3% of the Voting Eligible Series B Preferred Units voting as a class together with holders of any Series B Parity Securities established after the Series B Original Issue Date upon which like voting rights have been conferred and are exercisable, the Partnership shall not:

(1)    create or issue any Series B Parity Securities (including any additional Series B Preferred Units) if the cumulative distributions payable on Series B Preferred Units (or any Series B Parity Securities, if applicable) are in arrears; or

(2)    create or issue any Series B Senior Securities.

(D)    For any matter described in this Section 5.15 in which the holders of the Voting Eligible Series B Preferred Units (excluding any Series B Preferred Units that are held by the General Partner or any of its Affiliates) are entitled to vote as a class (whether separately or together with the holders of any Series B Parity Securities), such Series B Preferred Unitholders shall be entitled to one vote per Series B Preferred Unit.

(E)    Notwithstanding Sections 5.15(b)(ii)(B) and 5.15(b)(ii)(C) , no vote of the Series B Preferred Unitholders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series B Preferred Units at the time outstanding.

(iii)     Optional Redemption; Series B Rating Event .

(A)    The Partnership shall have the right to redeem the Series B Preferred Units, which redemption may be in whole or in part (except with respect to a Series B Rating Event Redemption which shall be in whole but not in part), in each case using any source of funds legally available for such purpose:

(1)    at any time, and from time to time, on or after February 15, 2023; or

(2)    at any time within 120 days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series B Rating Event (a “ Series B Rating Event Redemption ”).

(B)    Any such redemption shall occur on a date set by the General Partner (the “ Series B Redemption Date ”). The Partnership shall effect any such redemption by paying cash for each Series B Preferred Unit to be redeemed equal to the Series B Liquidation Preference for such Series B Preferred Unit on such Series B Redemption Date plus an amount equal to all accumulated and unpaid distributions thereon from the Series B Original Issue Date to, but not including, the Series B Redemption Date, whether or not such distributions shall have been declared (the “ Series B Redemption Price ”); provided that in connection with a Series B Rating Event Redemption, the Series B Liquidation Preference per Series B Preferred Unit shall be deemed to be equal to $1,020.00. So long as the Series B Preferred Units to be redeemed are held of record by the nominee of the Depository, the Series B Redemption Price shall be paid by the Paying Agent to the Depository on the Series B Redemption Date.

(C)    The Partnership shall give notice of any redemption not less than 10 days and not more than 60 days before the scheduled Series B Redemption Date to the Series B Preferred Unitholders of any Series B Preferred Units to be redeemed as such Series B Preferred Unitholders’ names appear on the books of the Transfer Agent and at the address of such Series B Preferred Unitholders shown therein. Such notice (the “ Series B

Redemption Notice ”) shall state, as applicable: (1) the Series B Redemption Date, (2) the number of Series B Preferred Units to be redeemed and, if less than all outstanding Series B Preferred Units are to be redeemed, the number (and the identification) of Series B Preferred Units to be redeemed from such Series B Preferred Unitholder, (3) the Series B Redemption Price, (4) the place where any Series B Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series B Redemption Price therefor and (5) that distributions on the Series B Preferred Units to be redeemed shall cease to accumulate from and after such Series B Redemption Date.

(D)    If the Partnership elects to redeem less than all of the outstanding Series B Preferred Units, the number of Series B Preferred Units to be redeemed shall be determined by the General Partner, and such Series B Preferred Units shall be redeemed by such method of selection as the Depository (or, in the case of any units not held of record by the nominee of the Depository, the General Partner) determines, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series B Preferred Units. So long as all Series B Preferred Units are held of record by the nominee of the Depository, the Partnership shall give the Series B Redemption Notice, or cause the Series B Redemption Notice to be given, to the Depository of the number of such Series B Preferred Units to be redeemed, and the Depository shall determine the number of such Series B Preferred Units to be redeemed from the account of each of its participants holding such Series B Preferred Units in its participant account. Thereafter, each participant shall select the number of the Series B Preferred Units to be redeemed from each beneficial owner for whom it acts (including the participant, to the extent it holds the Series B Preferred Units for its own account). A participant may determine to redeem the Series B Preferred Units from some beneficial owners (including the participant itself) without redeeming the Series B Preferred Units from the accounts of other beneficial owners. Any Series B Preferred Units not redeemed shall remain outstanding and entitled to all the rights and preferences of the Series B Preferred Units under the Agreement. So long as the Series B Preferred Units are held of record by the nominee of the Depository, the Series B Redemption Price shall be paid by the Paying Agent to the Depository on the Series B Redemption Date. If the Partnership gives or causes to be given a Series B Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series B Preferred Units as to which such Series B Redemption Notice shall have been given, no later than 10:00 a.m., New York City time, on the Series B Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series B Redemption Price to the Series B Preferred Unitholders whose Series B Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series B Preferred Units is issued in the name of the Depository or its nominee) of the Certificates therefor as set forth in the Series B Redemption Notice. If the Series B Redemption Notice shall have been given, from and after the Series B Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series B Redemption Notice, all Series B Distributions on such Series B Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series B Preferred Units as Limited Partners with respect to such Series B Preferred Units to be redeemed shall cease, except the right to receive the Series B Redemption Price plus an amount equal to accumulated and unpaid Series B Distributions to, but not including, the Series B Redemption Date, whether or not declared, and such Series B Preferred Units may not thereafter be transferred on the books of the Transfer Agent or be deemed to be outstanding for any purpose whatsoever. The Partnership shall be entitled to receive from the Paying Agent the interest income, if any, earned on such funds deposited with the Paying Agent (to the extent that such interest income is not required to pay the Series B Redemption Price of the Series B Preferred Units to be redeemed), and the holders of any Series B Preferred Units so redeemed shall have no claim to any such interest income. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series B Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series B Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series B Preferred Unitholders entitled to such redemption or other payment shall have recourse only to the Partnership.

(E)    If only a portion of the Series B Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series B Preferred Units is registered in the name of the Depository or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series B Preferred Unitholders a new Certificate (or adjust the applicable book entry account) representing the number of Series B Preferred Units represented by the surrendered Certificate that have not been called for redemption. Notwithstanding any Series B Redemption Notice, no redemption of any Series B Preferred Units may be called for redemption until funds sufficient

to pay the full Series B Redemption Price, plus all accumulated and unpaid distributions to, but not including, the Series B Redemption Date, whether or not declared, have been deposited by the Partnership with the Paying Agent.

(F)    The Partnership and its Affiliates may from time to time purchase the Series B Preferred Units, subject to compliance with all applicable securities and other laws. Notwithstanding the foregoing, unless full cumulative Series B Distributions have been or contemporaneously are being paid or provided for on all outstanding Series B Preferred Units and any Series B Parity Securities through the Series B Distribution Period or the most recently completed respective distribution period for such Series B Parity Securities, the Partnership may not repurchase, redeem or otherwise acquire, in whole or in part, any Series B Preferred Units or Series B Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all holders of the Series B Preferred Units and any Series B Parity Securities. Common Units and any other Series B Junior Securities may not be redeemed, repurchased or otherwise acquired unless full cumulative Series B Distributions have been or contemporaneously are being paid or provided for on all outstanding Series B Preferred Units and any Series B Parity Securities through the Series B Distribution Period or the most recently completed respective distribution period for such Series B Parity Securities.

(iv)     Ranking .

(A)    The Series B Preferred Units shall each be deemed to rank:

(1)    senior to any Series B Junior Securities;

(2)    pari passu with any Series B Parity Securities;

(3)    junior to any Series B Senior Securities; and

(4)    junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(B)    The Partnership may issue Series B Junior Securities and, subject to any approvals required pursuant to Section 5.15(b) (ii) , Series B Parity Securities from time to time in one or more classes or series without the consent of the Series B Preferred Unitholders. Pursuant to Section 5.6 , the General Partner has the authority to determine the preferences, powers, qualifications, limitations, restrictions and special or relative rights or privileges of any such class or series before the issuance of any Partnership Interests of such class or series.

(v)     No Sinking Fund . The Series B Preferred Units shall not have the benefit of any sinking fund.

(vi)     Record Holders . To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent and the Paying Agent may deem and treat any Series B Preferred Unitholder as the true, lawful and absolute owner of the applicable Series B Preferred Units for all purposes, and neither the General Partner, the Partnership nor the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series B Preferred Units are listed or admitted to trading.

(vii)     Notices . All notices or communications in respect of the Series B Preferred Units shall be sufficiently given if given in writing and delivered in person or by first class mail, postage prepaid, or if given in such other manner as may be permitted in this Agreement or by applicable law.

(viii)     Other Rights; Fiduciary Duties . The Series B Preferred Units and the Series B Preferred Unitholders shall not have any preferences, powers, qualifications, limitations, restrictions and special or relative rights or privileges, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, the Partnership, the General Partner and any other Indemnitee shall not owe any duties or have any liabilities to Series B Preferred Unitholders.

ARTICLE VI

ALLOCATIONS AND DISTRIBUTIONS

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

(a)     Net Income . After giving effect to the special allocations set forth in Section 6.1(d) , Net Income for each taxable period and all items of income, gain, loss and deduction taken into account in computing Net Income for such taxable period shall be allocated as follows:

(i)    First, to the General Partner as necessary to eliminate any deficit balance in the General Partner’s Capital Account; and

(ii)    Second, the balance, if any, to all Common Unitholders Pro Rata.

(b)     Net Loss . After giving effect to the special allocations set forth in Section 6.1(d) , Net Loss for each taxable period and all items of income, gain, loss and deduction taken into account in computing Net Loss for such taxable period shall be allocated as follows:

(i)    First, to the Common Unitholders, Pro Rata; provided , however , that Net Losses shall not be allocated pursuant to this Section 6.1(b)(i) to the extent that such allocation would cause any Common Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable period (or increase any existing deficit balance in its Adjusted Capital Account);

(ii)    Second, to the General Partner and the Common Unitholders to the extent of and in proportion to the positive balances in their Adjusted Capital Accounts;

(iii)    Third, to the Preferred Unitholders, to the extent of and in proportion to the positive balances in their Adjusted Capital Accounts; and

(iv)    The balance, if any, 100% to the General Partner.

(c)    [Reserved.]

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

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

(ii)     Chargeback of Partner Nonrecourse Debt Minimum Gain . Notwithstanding the other provisions of this Section 6.1 (other than Section 6.1(d)(i) ), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(d) , each Partner’s Adjusted Capital Account balance shall be determined, and the

allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d) and other than an allocation pursuant to Section 6.1(d)(i) , Section 6.1(d)(vi) and Section 6.1(d)(vii) with respect to such taxable period. This Section 6.1(d)(ii) is intended to comply with the chargeback of items of income and gain requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(iii)     Priority Allocations . If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4 or with respect to the Preferred Unitholders) with respect to a Limited Partner Unit exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Limited Partner Unit (the amount of the excess, an “ Excess Distribution ” and the Limited Partner Unit with respect to which the greater distribution is paid, an “ Excess Distribution Unit ” ) , then there shall be allocated gross income and gain to each Unitholder receiving an Excess Distribution with respect to the Excess Distribution Unit until the aggregate amount of such items allocated with respect to such Excess Distribution Unit pursuant to this Section 6.1(d)(iii) for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution. For the avoidance of doubt, this Section 6.1(d)(iii) shall not apply with respect to any disparity between a distribution to a Common Unit compared to (A) a distribution to a TexNew Mex Unit or (B) a distribution to a Common Unit subject to the conditions imposed by Section 6.4 .

(iv)     Qualified Income Offset . In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), or 1.704-1(b)(2)(ii)(d)(6), items of Partnership gross income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations promulgated under Section 704(b) of the Code, the deficit balance, if any, in its Adjusted Capital Account created by such adjustments, allocations or distributions as quickly as possible; provided , however , that an allocation pursuant to this Section 6.1(d)(iv) shall be made only if and to the extent that such Partner would have a deficit balance in its Adjusted Capital Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively made as if this Section 6.1(d)(iv) were not in this Agreement.

(v)     Gross Income Allocation . In the event any Partner has a deficit balance in its Capital Account at the end of any taxable period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and 1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided , however , that an allocation pursuant to this Section 6.1(d)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its Capital Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively made as if Section 6.1(d)(iv) and this Section 6.1(d)(v) were not in this Agreement.

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

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

(viii)     Nonrecourse Liabilities . For purposes of Treasury Regulation Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of the Partnership in excess of the sum of (A) the amount of Partnership Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall be allocated among the Partners Pro Rata; provided , however , that pursuant to Temporary Treasury Regulation Section 1.707-5T(a)(2)(i), liabilities shall be allocated for the purposes of Treasury Regulation Section 1.707-5 in accordance with the Partners’ interests in the Partnership’s profits, as determined by the General Partner.

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

(x)     Economic Uniformity; Changes in Law .

(A)    [Reserved.]

(B)    [Reserved.]

(C)    [Reserved.]

(D)    For the proper administration of the Partnership and for the preservation of uniformity of the Limited Partner Interests (or any class or classes thereof), the General Partner shall (1) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions; (2) make special allocations of income, gain, loss, deduction, Unrealized Gain or Unrealized Loss; and (3) amend the provisions of this Agreement as appropriate (x) to reflect the proposal or promulgation of Treasury Regulations under Section 704(b) or Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may adopt such conventions, make such allocations and make such amendments to this Agreement as provided in this Section 6.1(d)(x)(D) only if such conventions, allocations or amendments would not have a material adverse effect on the Partners, the holders of any class or classes of Limited Partner Interests issued and outstanding or the Partnership, and if such allocations are consistent with the principles of Section 704 of the Code.

(xi)     Allocations with Respect to Series A Preferred Units .

(A)    Items of Partnership gross income and gain shall be allocated to the Series A Preferred Unitholders, Pro Rata, until the aggregate amount of gross income and gain allocated to each Series A Preferred Unitholder pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all cash distributions made with respect to such Series A Preferred Unit pursuant to Section 5.14(b)(i) from the date such Series A Preferred Unit was issued to a date 60 days after the end of the current taxable year.

(B)    Items of Partnership gross income and gain shall be allocated to the Series A Preferred Unitholders, Pro Rata, until the aggregate amount of gross income and gain allocated to each Series A Preferred Unitholder pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Net Losses allocated to such Series A Preferred Unitholder pursuant to Section 6.1(b)(iii) for all previous taxable years.

(C)    Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (A) the Liquidation Date occurs prior to the conversion of the last outstanding Series A Preferred Unit and (B) after having made all other allocations provided for in this Section 6.1 for the taxable period in which the Liquidation Date occurs, the Per Unit Capital Amount of each Series A Preferred Unit would not equal or exceed the Series A Liquidation Value, then items of income, gain, loss and deduction for such taxable period shall instead be allocated among the Partners in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Series A Preferred Unit to equal the Series A Liquidation Value (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). For the avoidance of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Per Unit Capital Amount balances described above, items of income and gain that would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs, shall be reallocated from the Unitholders holding Limited Partner Units other than Series A Preferred Units to Unitholders holding Series A Preferred Units. In the event that (i) the Liquidation Date occurs on or before the date (not including any extension of time) prescribed by law for the filing of the Partnership’s federal

income tax return for the taxable period immediately prior to the taxable period in which the Liquidation Date occurs and (ii) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xi)(C) fails to achieve the Per Unit Capital Amounts described above, then items of income, gain, loss and deduction for such prior taxable period shall be reallocated among all Partners in a manner that will, to the maximum extent possible and after taking into account all other allocations made pursuant to this Section 6.1(d)(xi)(C) , cause the Per Unit Capital Amount in respect of each Series A Preferred Unit to equal the Series A Liquidation Value.

(xii)     Curative Allocation .

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

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

(xiii)     Allocations with Respect to Series B Preferred Units . For each taxable period that any Series B Preferred Units are outstanding, the Series B Preferred Unitholders shall be allocated, Pro Rata, gross income or gain equal to the excess, if any, of (x) the Series B Liquidation Preference with respect to such holder’s Series B Preferred Units, over (y) such holder’s existing Capital Account balance in respect of its Series B Preferred Units, until the Capital Account balance of each such holder in respect of its Series B Preferred Units is equal to the Series B Liquidation Preference in respect of such Series B Preferred Units.

(xiv)     Allocations for the TexNew Mex Shared Segment and the TexNew Mex Units .

(A)    For each taxable period that any TexNew Mex Units are outstanding, immediately following the application of Section 6.1(d)(iii) , the TexNew Mex Unitholders shall be allocated, Pro Rata, gross income or gain until the aggregate amount of such items allocated to the TexNew Mex Unitholders pursuant to this Section 6.1(d)(xiv)(A) for the current taxable period and all previous taxable periods is equal to the cumulative amount of all distributions made to the TexNew Mex Unitholders pursuant to Section 5.12(b)(iii) .

(B)    For each taxable period that any TexNew Mex Units are outstanding, the TexNew Mex Unitholders shall be allocated, Pro Rata, an amount equal to the sum of (1) the product of (x) the TexNew Mex Contributed Percentage times (y) the amount of depreciation, amortization, depletion or any other form of cost recovery attributable to the TexNew Mex Contributed Assets for such taxable period, plus (2) the amount of depreciation, amortization, depletion or any other form of cost recovery attributable to any Expansion Capital Expenditures or Investment Capital Expenditures funded by the Holdback Amounts. Any depreciation, amortization, depletion or any other form of cost recovery attributable to the TexNew Mex Contributed Assets or any Expansion Capital Expenditures or Investment Capital Expenditures not allocated pursuant to this Section 6.1(d)(xiv)(B) shall be allocated to the Partners other than the TexNew Mex Unitholders in accordance with Sections 6.1(a) through 6.1(c) .

(C)    For each taxable period that any TexNew Mex Units are outstanding, any items of Unrealized Gain or Unrealized Loss associated with the TexNew Mex Assets, or gain or loss recognized from the sale, exchange or other disposition of all or substantially all of the TexNew Mex Assets, taken as a whole, in a single transaction or a series of related transactions (excluding any disposition to a member of the Partnership Group) shall be allocated among the TexNew Mex Unitholders, Pro Rata, and the Partners other than the TexNew Mex Unitholders in a manner that is designed to provide that (1) the Partners other than the TexNew Mex Unitholders will bear 100% of the economic benefits and burdens associated with the TexNew Mex Assets having a fair market value of $180,000,000 or less at the time of such allocation, (2) the holders of the TexNew Mex Units will bear 100% of the economic benefits and burdens associated with the TexNew Mex Assets having a fair market value of more than $180,000,000 but not more than $260,000,000 at the time of such allocation, and (3) the economic benefits associated with the TexNew Mex Assets having a fair market value of more than $260,000,000 at the time of such allocation being borne 80% by the holders of the TexNew Mex Units and 20% by the Partners other than the TexNew Mex Unitholders. Any amounts allocable to the Partners other than the TexNew Mex Unitholders pursuant to the principles set forth in this Section 6.1(d)(xiv)(C) shall be allocated in accordance with Sections 6.1(a) through 6.1(c) .

(xv)     Special Limited Partner Interest Cost Recovery Deductions . For any taxable period ending after the effective time of the transactions contemplated by the ANDX Merger Agreement, any and all cost recovery deductions available to the Partnership with respect to the underlying Partnership assets attributable to the prior capital account in ANDX associated with the ANDX Special Limited Partner Interest may, at the General Partner’s discretion, in whole or in part, be allocated to the holder of the Special Limited Partner Interest until the portion of the Capital Account with respect to such Special Limited Partner Interest that is attributable to the ANDX Special Limited Partner Interest is reduced to zero. In order to effect the allocations pursuant to this Section 6.1(d)(xv) and in maintaining the Partnership’s Capital Accounts, the General Partner shall apply the “keep-your-own” method of accounting with respect to the portion of the Capital Account with respect to the Special Limited Partner Interest that is attributable to the ANDX Special Limited Partner Interest.

Section 6.2     Allocations for Tax Purposes .

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

(b)    In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall be allocated for federal income tax purposes among the Partners in the manner provided under Section 704(c) of the Code, and the Treasury Regulations promulgated under Section 704(b) and 704(c) of the Code, as determined to be appropriate by the General Partner (taking into account the General Partner’s discretion under Section 6.1(d)(x)(D) ); provided, however, that the General Partner shall apply the principles of Treasury Regulation Section 1.704-3(d) in all events.

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

(d)    In accordance with Treasury Regulation Sections 1.1245-1(e) and 1.1250-1(f), any gain allocated to the Partners upon the sale or other taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 6.2 , be characterized as Recapture Income in

the same proportions and to the same extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income.

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

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

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

(h)    If, as a result of the conversion of a Series A Preferred Unit into Common Units and the adjustments pursuant to Section 5.5(d)(iii) , a Capital Account reallocation is required consistent with the principles of Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x).

Section 6.3     Requirement and Characterization of Distributions; Distributions to Record Holders .

(a)    Subject to Section 5.12(b)(iii)(B) , Section 5.14(b)(i)(B) and Section 5.15(b)(i)(B) , within 60 days following the end of each Quarter, an amount equal to 100% of Available Cash with respect to such Quarter shall be distributed in accordance with this Article VI , by the Partnership Pro Rata to the Common Unitholders as of the Record Date selected by the General Partner. All amounts of Available Cash distributed by the Partnership on any date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash theretofore distributed by the Partnership to the Limited Partners pursuant to this Section 6.3 equals the Operating Surplus from the Closing Date through the close of the immediately preceding Quarter. Any remaining amounts of Available Cash distributed by the Partnership on such date shall be deemed to be “Capital Surplus.” For the avoidance of doubt, the holders of the Series A Preferred Units , the Series B Preferred Units, the TexNew Mex Units, the Special Limited Partner Interest and the General Partner Interest shall not be entitled to distributions made pursuant to this Section 6.3(a) in respect of such Partnership Interests. Notwithstanding any provision to the contrary contained in this Agreement, the Partnership shall not make a distribution to any Partner on account of its interest in the Partnership if such distribution would violate the Delaware Act or any other applicable law. All distributions required to be made under this Agreement shall be made subject to Sections 17-607 and 17-804 of the Delaware Act and other applicable law, notwithstanding any other provision of this Agreement.

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

(c)    Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction

of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise.

Section 6.4     Reduction of Common Unit Distributions .

(a)    The aggregate quarterly distributions of Available Cash in respect of the Common Units held by the General Partner and its Affiliates shall be reduced (in the aggregate) by $12,500,000 per Quarter commencing with distributions with respect to the Quarter ending June 30, 2019 and ending with distributions with respect to the Quarter ending December 31, 2019.

(b)    Prior to the date following the Record Date related to distributions with respect to the Quarter ending December 31, 2019, the General Partner and its Affiliates shall not transfer any Common Units if such transfer will result in the General Partner and its Affiliates owning, in the aggregate, a number of Common Units less than the number of Common Units reasonably required to provide for the remaining reduction in distributions set forth in Section 6.4(a) .

Section 6.5     Special Distributions in Consideration of Contributions by Partners . Notwithstanding anything to the contrary set forth in this Agreement, the General Partner may, from time-to-time, cause the Partnership to make special distributions of cash to one or more Partners in connection with, and in full or partial consideration of, the contribution, assignment, transfer or conveyance of property, assets or rights or any interests therein by such Partners to the Partnership, including, but not limited to, a distribution pursuant to Treasury Regulation Section 1.707-5(b). For the avoidance of doubt, such special distributions shall not be considered distributions of Available Cash and shall not be subject to, or required to be distributed in accordance with, Section 6.3 (other than the last two sentences of Section 6.3(a) ) or Section 12.4(c) .

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

Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7 . Any allocation of expenses to the Partnership by the General Partner in a manner consistent with its or its Affiliates’ past business practices and, in the case of assets regulated by FERC, then applicable accounting and allocation methodologies generally permitted by FERC for rate-making purposes (or in the absence of then-applicable methodologies permitted by FERC, consistent with the most-recently applicable methodologies), shall be deemed to have been made in good faith.

Interests in connection with, or pursuant to, any employee benefit plan, employee program or employee practice maintained or sponsored by the General Partner or any of its Affiliates in each case for the benefit of officers, employees and directors of the General Partner or any of its Affiliates, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General Partner or any of its Affiliates any Partnership Interests that the General Partner or such Affiliates are obligated to provide to any officers, employees, consultants and directors pursuant to any such employee benefit plans, employee programs or employee practices.

Any and all obligations of the General Partner under any employee benefit plans, employee programs or employee practices adopted by the General Partner as permitted by this Section 7.4(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or Section 11.2 or the transferee of or successor to all of the General Partner’s General Partner Interest pursuant to Section 4.6 .

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

(b)    Subject to the terms of Section 7.5(c) , each Unrestricted Person (other than the General Partner) shall have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member, and none of the same shall constitute a breach of this Agreement or any duty otherwise existing at law, in equity or otherwise, to any Group Member or any Partner. None of any Group Member, any Limited Partner or any other Person shall have any rights by virtue of this Agreement, any Group Member Agreement, or the partnership relationship established hereby in any business ventures of any Unrestricted Person.

(c)    Subject to the terms of Section 7.5(a) and Section 7.5(b) , but otherwise notwithstanding anything to the contrary in this Agreement, (i) the engaging in competitive activities by any Unrestricted Person (other than the General Partner) in accordance with the provisions of this Section 7.5 is hereby approved by the Partnership and all Partners, (ii) it shall be deemed not to be a breach of any duty or any other obligation of any type whatsoever of the General Partner or any other Unrestricted Person for the Unrestricted Persons (other than the General Partner) to engage in such business interests and activities in preference to or to the exclusion of the Partnership and (iii) the Unrestricted Persons shall have no obligation hereunder or as a result of any duty otherwise existing at law, in equity or otherwise, to present business opportunities to the Partnership. Notwithstanding anything to the contrary in this Agreement or any duty otherwise existing at law or in equity, the doctrine of corporate opportunity, or any analogous doctrine, shall not apply to any Unrestricted Person (including the General Partner). No Unrestricted Person (including

the General Partner) who acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to the Partnership, and such Unrestricted Person (including the General Partner) shall not be liable to the Partnership, to any Limited Partner or any other Person bound by this Agreement for breach of any duty by reason of the fact that such Unrestricted Person (including the General Partner) pursues or acquires for itself, directs such opportunity to another Person or does not communicate such opportunity or information to the Partnership, provided that such Unrestricted Person does not engage in such business or activity using confidential or proprietary information provided by or on behalf of the Partnership to such Unrestricted Person.

(d)    The General Partner and each of its Affiliates may acquire Limited Partner Units or other Partnership Interests in addition to those acquired on the Closing Date and, except as otherwise provided in this Agreement, shall be entitled to exercise, at their option, all rights relating to all Limited Partner Units and/or other Partnership Interests acquired by them.

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

(a)    The General Partner or any of its Affiliates may lend to any Group Member, and any Group Member may borrow from the General Partner or any of its Affiliates, funds needed or desired by the Group Member for such periods of time and in such amounts as the General Partner may determine; provided , however , that in any such case the lending party may not charge the borrowing party interest at a rate greater than the rate that would be charged the borrowing party or impose terms less favorable to the borrowing party than would be charged or imposed on the borrowing party by unrelated lenders on comparable loans made on an arm’s-length basis (without reference to the lending party’s financial abilities or guarantees), all as determined by the General Partner. The borrowing party shall reimburse the lending party for any costs (other than any additional interest costs) incurred by the lending party in connection with the borrowing of such funds. For purposes of this Section 7.6(a) and Section 7.6(b) , the term “Group Member” shall include any Affiliate of a Group Member that is controlled by the Group Member.

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

(c)    No borrowing by any Group Member or the approval thereof by the General Partner shall be deemed to constitute a breach of any duty, expressed or implied, of the General Partner or its Affiliates to the Partnership or the Limited Partners existing hereunder, or existing at law, in equity or otherwise by reason of the fact that the purpose or effect of such borrowing is directly or indirectly to enable distributions to the General Partner or its Affiliates (including in their capacities as Limited Partners) to exceed the General Partner’s Percentage Interest of the total amount distributed to all Partners.

Section 7.7     Indemnification .

(a)    To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Indemnitees shall be indemnified and held harmless by the Partnership from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending or completed claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals, in which any Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as an Indemnitee and acting (or refraining to act) in such capacity on behalf of or for the benefit of the Partnership; provided , that the Indemnitee shall not be indemnified and held harmless pursuant to this Agreement if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Agreement, the Indemnitee acted in bad faith or engaged in intentional fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful; provided , further , no indemnification pursuant to this Section 7.7 shall be available to any Affiliate of the General Partner (other than a Group Member), or to any other Indemnitee, with respect to any such Affiliate’s obligations pursuant to the

Transaction Documents. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Partnership to enable it to effectuate such indemnification.

(b)    To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by an Indemnitee who is indemnified pursuant to Section 7.7(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Partnership prior to a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee is seeking indemnification pursuant to this Section 7.7 , the Indemnitee is not entitled to be indemnified upon receipt by the Partnership of any undertaking by or on behalf of the Indemnitee to repay such amount if it shall be ultimately determined that the Indemnitee is not entitled to be indemnified as authorized by this Section 7.7 .

(c)    The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee may be entitled under any agreement, pursuant to any vote of the holders of Voting Eligible Limited Partner Interests, as a matter of law, in equity or otherwise, both as to actions in the Indemnitee’s capacity as an Indemnitee and as to actions in any other capacity (including any capacity under the IPO Underwriting Agreement), and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Indemnitee.

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

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

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

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

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

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

Section 7.8     Liability of Indemnitees .

(a)    Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the Partnership, the Limited Partners, or any other Persons who are bound by this Agreement for losses sustained or liabilities incurred as a result of any act or omission of an Indemnitee unless there has been a

final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter in question, the Indemnitee acted in bad faith or engaged in intentional fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal.

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

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

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

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

(a)    Unless otherwise expressly provided in this Agreement or any Group Member Agreement, whenever a potential conflict of interest exists or arises between the General Partner or any of its Affiliates, on the one hand, and the Partnership, any Group Member or any Partner, on the other, any resolution or course of action by the General Partner or its Affiliates in respect of such conflict of interest shall be permitted and deemed approved by all Partners, and shall not constitute a breach of this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any duty stated or implied by law or equity, if the resolution or course of action in respect of such conflict of interest is (i) approved by Special Approval, (ii) approved by the vote of a majority of the Voting Eligible Common Units (excluding Common Units owned by the General Partner and its Affiliates) and Series A Preferred Units voting together as a single class, (iii) on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iv) fair and reasonable to the Partnership, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to the Partnership). The General Partner shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval or Unitholder approval of such resolution, and the General Partner may also adopt a resolution or course of action that has not received Special Approval or Unitholder approval. Whenever the General Partner makes a determination to refer any potential conflict of interest to the Conflicts Committee for Special Approval, seek Unitholder approval or adopt a resolution or course of action that has not received Special Approval or Unitholder approval, then the General Partner shall be entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty or obligation whatsoever to the Partnership or any Limited Partner, and the General Partner shall not, to the fullest extent permitted by law, be required to act in good faith or pursuant to any other standard or duty imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the General Partner in making such determination or taking or declining to take such other action shall be permitted to do so in its sole and absolute discretion. If Special Approval is sought, then it shall be presumed that, in making its decision, the Conflicts Committee acted in good faith, and if the Board of Directors determines that the resolution or course of action taken with respect to a conflict of interest satisfies either of the standards set forth in clauses ( iii ) or ( iv ) above or that a director satisfies the eligibility requirements to be a member of the Conflicts Committee, then it shall be presumed that, in making its decision, the Board of Directors acted in good faith. In any proceeding brought by any Limited Partner or by or on behalf of such Limited Partner or any other Limited Partner or the Partnership challenging any action by the Conflicts Committee with respect to any matter referred to the Conflicts Committee for Special Approval by the General Partner, any determination by the Board of Directors that the resolution or course of action taken with respect to a conflict of interest satisfies either of the standards set forth in clauses ( iii ) or ( iv ) above or any determination by the Board of Directors that a director satisfies the eligibility requirements to be a member of the Conflicts Committee, the Person bringing or prosecuting such proceeding shall have the burden of overcoming the presumption that the Conflicts

Committee or the Board of Directors, as applicable, acted in good faith. Notwithstanding anything to the contrary in this Agreement or any duty otherwise existing at law or equity, the existence of the conflicts of interest described in the IPO Registration Statement are hereby approved by all Partners and shall not constitute a breach of this Agreement or any such duty.

(b)    Whenever the General Partner or the Board of Directors, or any committee thereof (including the Conflicts Committee), makes a determination or takes or declines to take any other action, or any Affiliate of the General Partner causes the General Partner to do so, in its capacity as the general partner of the Partnership as opposed to in its individual capacity, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then, unless another express standard is provided for in this Agreement, the General Partner, the Board of Directors or such committee or such Affiliates causing the General Partner to do so, shall make such determination or take or decline to take such other action in good faith and shall not be subject to any other or different standards (including fiduciary standards) imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. A determination or other action or inaction will conclusively be deemed to be in “good faith” for all purposes of this Agreement, if the Person or Persons making such determination or taking or declining to take such other action subjectively believe that the determination or other action or inaction is not adverse to the best interests of the Partnership Group.

(c)    Whenever the General Partner makes a determination or takes or declines to take any other action, or any of its Affiliates causes it to do so, in its individual capacity as opposed to in its capacity as the general partner of the Partnership, whether under this Agreement, any Group Member Agreement or any other agreement contemplated hereby or otherwise, then the General Partner, or such Affiliates causing it to do so, are entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty or obligation whatsoever to the Partnership or any Limited Partner, and the General Partner, or such Affiliates causing it to do so, shall not, to the fullest extent permitted by law, be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the Person or Persons making such determination or taking or declining to take such other action shall be permitted to do so in their sole and absolute discretion. By way of illustration and not of limitation, whenever the phrase, “the General Partner at its option,” or some variation of that phrase, is used in this Agreement, it indicates that the General Partner is acting in its individual capacity. For the avoidance of doubt, whenever the General Partner votes or transfers its Partnership Interests, or refrains from voting or transferring its Partnership Interests, it shall be acting in its individual capacity.

(d)    The General Partner’s organizational documents may provide that determinations to take or decline to take any action in its individual, rather than representative, capacity may or shall be determined by its members, if the General Partner is a limited liability company, stockholders, if the General Partner is a corporation, or the members or stockholders of the General Partner’s general partner, if the General Partner is a partnership.

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

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

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

Section 7.10     Other Matters Concerning the General Partner and Other Indemnitees .

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

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

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

Section 7.11     Purchase or Sale of Partnership Interests . The General Partner may cause the Partnership to purchase or otherwise acquire Partnership Interests or Derivative Partnership Interests. As long as Partnership Interests are held by any Group Member, such Partnership Interests shall not be considered outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General Partner may also purchase or otherwise acquire and sell or otherwise dispose of Partnership Interests for its own account, subject to the provisions of Articles IV and X.

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

(a)     Demand Registration . Upon receipt of a Notice from any Holder at any time after the 180th day after the Closing Date, the Partnership shall file with the Commission as promptly as reasonably practicable a registration statement under the Securities Act (each, a “ Registration Statement ”) providing for the resale of the Registrable Securities, which may, at the option of the Holder giving such Notice, be a Registration Statement that provides for the resale of the Registrable Securities from time to time pursuant to Rule 415 under the Securities Act. The Partnership shall not be required pursuant to this Section 7.12(a) to file more than one Registration Statement in any twelve-month period nor to file more than three Registration Statements in the aggregate. The Partnership shall use commercially reasonable efforts to cause such Registration Statement to become effective as soon as reasonably practicable after the initial filing of the Registration Statement and to remain effective and available for the resale of the Registrable Securities by the Selling Holders named therein until the earlier of (i) six months following such Registration Statement’s effective date and (ii) the date on which all Registrable Securities covered by such Registration Statement have been sold. In the event one or more Holders request in a Notice to dispose of a number of Registrable Securities that such Holder or Holders reasonably anticipates will result in gross proceeds of at least $30,000,000 in the aggregate pursuant to a Registration Statement in an Underwritten Offering, the Partnership shall retain underwriters that are reasonably acceptable to such Selling Holders in order to permit such Selling Holders to effect such disposition through an Underwritten Offering; provided , however , that the Partnership shall have the exclusive right to select the bookrunning managers. The Partnership and such Selling Holders shall enter into an underwriting agreement in customary form that is reasonably acceptable to the Partnership and take all reasonable actions as are requested by the managing underwriters to facilitate the Underwritten Offering and sale of Registrable Securities therein. No Holder may participate in the Underwritten Offering unless it agrees to sell its Registrable Securities covered by the Registration Statement on the terms and conditions of the underwriting agreement and completes and delivers all necessary documents and information reasonably required under the terms of such underwriting agreement. In the event that the managing underwriter of such Underwritten Offering advises the Partnership and the Holder in writing that in its opinion the inclusion of all or some Registrable Securities would adversely and materially affect the timing or success of the Underwritten Offering, the amount of Registrable Securities that each Selling Holder requested be included in such Underwritten Offering shall be reduced on a Pro Rata basis to the aggregate amount that the managing underwriter deems will not have such material and adverse effect. Any Holder may withdraw from such Underwritten Offering by notice to the Partnership and the managing underwriter; provided such notice is delivered prior to the launch of such Underwritten Offering.

(b)     Piggyback Registration . At any time after the 180th day after the Closing Date, if the Partnership shall propose to file a Registration Statement (other than pursuant to a demand made pursuant to Section 7.12(a) ) for an offering of Partnership Interests for cash (other than an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or an offering on any registration statement that does not permit secondary sales), the Partnership shall notify all Holders of such proposal at least five Business Days before the proposed filing date. The Partnership shall use commercially reasonable efforts to include such number of Registrable Securities held by any Holder in such Registration Statement as each Holder shall request in a Notice received by the Partnership within two Business Days of such Holder’s receipt of the notice from the Partnership. If the Registration Statement about which the Partnership gives notice under this Section 7.12(b) is for an Underwritten Offering, then any Holder’s ability to include its desired amount of Registrable Securities in such Registration Statement shall be conditioned on such Holder’s inclusion of all such Registrable Securities in the Underwritten Offering; provided that, in the event that the managing underwriter of such Underwritten Offering advises the Partnership and the Holder in writing that in its opinion the inclusion of all or some Registrable Securities would adversely and materially affect the timing or success of the Underwritten Offering, the amount of Registrable Securities that each Selling Holder requested be included in such Underwritten Offering shall be reduced on a Pro Rata basis to the aggregate amount that the managing underwriter deems will not have such material and adverse effect. In connection with any such Underwritten Offering, the Partnership and the Selling Holders involved shall enter into an underwriting agreement in customary form that is reasonably acceptable to the Partnership and take all reasonable actions as are requested by the managing underwriters to facilitate the Underwritten Offering and sale of Registrable Securities therein. No Holder may participate in the Underwritten Offering unless it agrees to sells its Registrable Securities covered by the Registration Statement on the terms and conditions of the underwriting agreement and completes and delivers all necessary documents and information reasonably required under the terms of such underwriting agreement. Any Holder may withdraw from such Underwritten Offering by notice to the Partnership and the managing underwriter; provided such notice is delivered prior to the launch of such Underwritten Offering. The Partnership shall have the right to terminate or withdraw any Registration Statement or Underwritten Offering initiated by it under this Section 7.12(b) prior to the effective date of the Registration Statement or the pricing date of the Underwritten Offering, as applicable.

(c)     Sale Procedures . In connection with its obligations under this Section 7.12 , the Partnership shall:

(i)    furnish to each Selling Holder (A) as far in advance as reasonably practicable before filing a Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing a Registration Statement or supplement or amendment thereto, and (B) such number of copies of such Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement; provided , however , that the Partnership will not have any obligation to provide any document pursuant to clause (A) hereof that is available on the Commission’s website;

(ii)    if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by a Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the managing underwriter, shall reasonably request; provided, however, that the Partnership will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any jurisdiction where it is not then so subject;

(iii)    promptly notify each Selling Holder and each underwriter, at any time when a prospectus is required to be delivered under the Securities Act, of (A) the filing of a Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any post-effective amendment thereto, when the same has become effective; and (B) any written comments from the Commission with respect to any Registration Statement or any document incorporated by reference therein and any written request by the Commission for amendments or supplements to a Registration Statement or any prospectus or prospectus supplement thereto;

(iv)    immediately notify each Selling Holder and each underwriter, at any time when a prospectus is required to be delivered under the Securities Act, of (A) the occurrence of any event or existence of any fact (but not a description of such event or fact) as a result of which the prospectus or prospectus supplement contained in a Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of the prospectus contained therein, in the light of the circumstances under which a statement is made); (B) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement, or the initiation of any proceedings for that purpose; or (C) the receipt by the Partnership of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, subject to Section 7.12(f) , the Partnership agrees to, as promptly as practicable, amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; and

(v)    enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of the Registrable Securities, including the provision of comfort letters and legal opinions as are customary in such securities offerings.

(d)     Suspension . Each Selling Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described in Section 7.12(c)(iv) , shall forthwith discontinue disposition of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by such subsection or until it is advised in writing by the Partnership that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus.

(e)     Expenses . Except as set forth in an underwriting agreement for the applicable Underwritten Offering or as otherwise agreed between a Selling Holder and the Partnership, all costs and expenses of a Registration Statement filed or an Underwritten Offering that includes Registrable Securities pursuant to this Section 7.12 (other than underwriting discounts and commissions on Registrable Securities and fees and expenses of counsel and advisors to Selling Holders) shall be paid by the Partnership.

(f)     Delay Right . Notwithstanding anything to the contrary herein, if the General Partner determines that the Partnership’s compliance with its obligations in this Section 7.12 would be detrimental to the Partnership because such registration would (x) materially interfere with a significant acquisition, reorganization or other similar transaction involving the Partnership, (y) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (z) render the Partnership unable to comply with requirements under applicable securities laws, then the Partnership shall have the right to postpone compliance with such obligations for a period of not more than six months; provided , however , that such right may not be exercised more than twice in any 24-month period.

(g)     Indemnification .

(i)    In addition to and not in limitation of the Partnership’s obligation under Section 7.7 , the Partnership shall, to the fullest extent permitted by law, indemnify and hold harmless each Selling Holder, its officers, directors and each Person who controls the Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “ Indemnified Persons ”) from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (hereinafter referred to in this Section 7.12(g) as a “claim” and in the plural as “claims”) based upon, arising out of or resulting from any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, preliminary prospectus, final prospectus or issuer free writing prospectus under which any Registrable Securities were registered or sold under the Securities Act, or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required

to be stated therein or necessary to make the statements therein not misleading; provided , however , that the Partnership shall not be liable to any Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus or issuer free writing prospectus in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Indemnified Person specifically for use in the preparation thereof.

(ii)    Each Selling Holder shall, to the fullest extent permitted by law, indemnify and hold harmless the Partnership, the General Partner, the General Partner’s officers and directors and each Person who controls the Partnership or the General Partner (within the meaning of the Securities Act) and any agent thereof to the same extent as the foregoing indemnity from the Partnership to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in a Registration Statement, prospectus or free writing prospectus relating to the Registrable Securities held by such Selling Holder.

(iii)    The provisions of this Section 7.12(g) shall be in addition to any other rights to indemnification or contribution that a Person entitled to indemnification under this Section 7.12(g) may have pursuant to law, equity, contract or otherwise.

(h)     Specific Performance . Damages in the event of breach of Section 7.12 by a party hereto may be difficult, if not impossible, to ascertain, and it is therefore agreed that each party, in addition to and without limiting any other remedy or right it may have, will have the right to seek an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives, to the fullest extent permitted by law, any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such party from pursuing any other rights and remedies at law or in equity that such party may have.

Section 7.13     Reliance by Third Parties . Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner and any officer of the General Partner authorized by the General Partner to act on behalf of and in the name of the Partnership has full power and authority to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any authorized contracts on behalf of the Partnership, and such Person shall be entitled to deal with the General Partner or any such officer as if it were the Partnership’s sole party in interest, both legally and beneficially. Each Limited Partner hereby waives, to the fullest extent permitted by law, any and all defenses or other remedies that may be available against such Person to contest, negate or disaffirm any action of the General Partner or any such officer in connection with any such dealing. In no event shall any Person dealing with the General Partner or any such officer or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the General Partner or any such officer or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (a) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (b) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (c) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership.
