 Exhibit 10.1 
 AGREEMENT 
 THIS AGREEMENT (the “Agreement”)
is made and entered into to be effective as of the 29th
day of October, 2012 (the “Commencement Date”), by and between ViewPoint Bank (which, together with any successor thereto which executes and delivers the assumption agreement required by Section 8(a) hereof or which otherwise becomes bound
by all of the terms and provisions of this Agreement by agreement, operation of law or otherwise, is hereinafter referred to as the “Bank”), and
                    (the “Employee”). 
 WHEREAS, the Employee now serves in the position of                     of the Bank; and 

WHEREAS, the Compensation Committee of the Bank (the “Compensation Committee”) believes it is in the best interests of the Bank
to enter into this Agreement with the Employee to assure continuity of management of the Bank and to reinforce and to encourage the continued dedication of the Employee to the Employee’s assigned duties; and 

WHEREAS, the Compensation Committee has approved and authorized the execution of this Agreement with the Employee; 

NOW, THEREFORE, in consideration of the foregoing and of the respective covenants and agreements of the parties herein, it is AGREED as
follows: 
 1. Certain Definitions. 
 “Affiliate” means any entity required to be part of an affiliated group (as defined in Code Section 1504, without regard to subsection (b) thereof) that includes the Bank.

 “Code” means the Internal Revenue Code of 1986, as amended from time to time. “Commencement
Date” means the date of this Agreement. 
 “Date of Termination” means the date upon which the
Employee experiences a Separation from Service. 
 “Involuntary Termination” means the termination of the
employment of Employee (i) by the Bank, without the Employee’s express written consent; or (ii) by the Employee by reason of a material diminution of or interference with his duties, responsibilities or benefits, including any of the
following actions unless consented to in writing by the Employee: (1) a requirement that the Employee be based at any place other than Plano, Texas, or within a radius of 35 miles from the location of the Bank’s administrative offices as
of the Commencement Date, except for reasonable travel on Bank business; (2) a material demotion of the Employee; (3) a material reduction in the number or seniority of personnel reporting to the Employee other than as part of a Bank-wide
reduction in staff; and (4) a reduction in the Employee’s salary, other than as part of an overall program applied uniformly and with equitable effect to all members of the senior management of the Bank. The term “Involuntary
Termination” does not include Termination for Cause, retirement, death, disability, or suspension or temporary or permanent prohibition from participation in the conduct of the Bank’s affairs under Section 8 of the Federal Deposit
Insurance Act. 

  
 1 

 “One-Year Term” means the 365-day period commencing on the date following
the Employee’s Separation from Service. 
 “Section 409A” means Section 409A of the Code and the
regulations and guidance of general applicability issued thereunder. 
 “Separation from Service” shall have
the same meaning as in Section 409A, taking into account the rules and presumptions provided for in Treasury Regulation Section 1.409A-1(h) or any successor regulation. Notwithstanding the foregoing, for purposes of determining whether the
Employee is entitled to a payment on account of Involuntary Termination under Section 2 of this Agreement, and for purposes of determining the Employee’s One-Year Term, the term “Separation from Service” shall require the
complete cessation of services to the Bank and all Affiliates. 
 “Termination for Cause” and
“Terminated for Cause” mean termination of the employment of the Employee because of the Employee’s personal dishonesty, willful misconduct, breach of a fiduciary duty involving personal profit, intentional failure to perform
stated duties, willful violation of any law, rule, or regulation (other than traffic violations or similar offenses) or final cease-and-desist order, or (except as provided below) material breach of any provision of this Agreement. No act or failure
to act by the Employee shall be considered willful unless the Employee acted or failed to act with an absence of good faith and without a reasonable belief that his action or failure to act was in the best interest of the Bank. The Employee shall
not be deemed to have been Terminated for Cause unless and until there shall have been delivered to the Employee a copy of a resolution, duly adopted by the affirmative vote of not less than a majority of the entire membership of the Board of
Directors at a meeting of the Board duly called and held for such purpose (after reasonable notice to the Employee and an opportunity for the Employee, together with the Employee’s counsel, to be heard before the Board), stating that in the
good faith opinion of the Board of Directors the Employee has engaged in conduct described in the preceding sentence and specifying the particulars thereof in detail. 
 2. Term. The term of this Agreement shall be a period of one year beginning on the Commencement Date, subject to earlier termination as provided herein. On the first anniversary of the Commencement
Date, and on each anniversary thereafter, the term of this Agreement shall be extended for a period of one year, provided that the Bank has not given notice to Employee in writing at least 90 days prior to such anniversary date that the term of this
Agreement shall not be extended further. The Secretary of the Bank (or any Assistant Secretary) shall provide a written reminder to the Board of the renewal provisions of this Section 2 at least 120 days prior to each anniversary of this Agreement
occurring during the term. Reference herein to the term of this Agreement shall refer to both such initial term and such extended terms. 
 3. Severance Benefits: Mitigation; Conditions for Payment. 
 (a) (1) If the
Employee experiences an Involuntary Termination, the Bank shall (i) continue to pay the Employee’s base salary, as in effect on the Termination Date, for the One-Year Term, and (ii) provide to the Employee during the One-Year Term, at
the Bank’s expense, the hospitalization, medical, dental, prescription drug and other health benefits required to be provided under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended from time to time (“COBRA”).
Benefits provided under (ii) above shall not extend the period during which the Employee is entitled to benefits under COBRA. 

  
 2 

 (2) To the extent the taxable payments under Section 3(a)(l) would be considered
deferred compensation and the Employee is considered a “specified employee” (as defined in Section 409A), no deferred compensation shall be paid until the 185th day following the Employee’s Separation from Service (and any
deferred compensation the payment of which is delayed on account of the foregoing shall be paid on such 185th day). The preceding sentence shall be applied by (i) treating as much of the payment due under Section 3(a)(l) as
“separation pay due to involuntary separation from service” (within the meaning of Treasury Regulation Section 1.409A-l(b)(9)) (“Separation Pay”) as is possible, so that such Separation Pay may be paid without regard to the
preceding sentence, and (ii) treating the Separation Pay as paid prior to the deferred compensation, to the extent permitted by Section 409A. 
 (3) No payment shall be made under Section 3(a) that would cause the Bank to be “undercapitalized” for purposes of 12 C.F.R. Part 225 or any successor provision. 

(b) Amounts received by the Employee with respect to services performed by the Employee as an employee or independent contractor of any
nature during the One-Year Term (regardless of the manner paid, including but not limited to wages, bonuses, self-employment income, deferred compensation, stock or other equity-based compensation, performance or incentive-based compensation, fringe
benefits, and contributions to a qualified plan, and regardless of when paid) shall reduce the amounts payable by the Bank under Section 3(a)(l)(i) on a dollar for dollar basis (the “Mitigation Amount”). Notwithstanding the foregoing,
amounts paid from a deferred compensation plan, tax-qualified retirement plan (within the meaning of Code Section 40l(a)) or equity-based compensation plan sponsored or maintained by the Bank or any Affiliate shall not be taken into account in
determining the Employee’s Mitigation Amount. Upon request by the Bank, the Employee shall provide such information as is necessary to determine the Mitigation Amount. If there are Mitigation Amounts, the Bank may reduce or suspend payments
under this Agreement, or seek recovery from the Employee. 
 (c) During the One-Year Term, the Employee shall be provided with
reasonable outplacement services. The manner and type of outplacement services provided to the Employee shall be determined by the Bank in its sole discretion, and may be different than the outplacement services provided to other Employees.

 (d) Payments under this Section 3 are subject to the Employee’s full compliance with the requirement of
Section 4. If the provisions of Section 4 are violated, the Bank may reduce or eliminate payments described in this Section 3, or seek appropriate recovery. 
 (e) Payments under this Section 3 are subject to the Employee’s executing a release substantially in the form provided for in Exhibit A attached hereto. 

4. Future Conduct and Obligations. 
 (a) Nondisparagement. The Employee, for himself and for his family (i.e., parents, siblings and children), heirs, dependents, assigns, agents, executors, administrators, trustees and legal
representatives agrees that he will not (and will use his best efforts to cause such affiliates to not) at any time engage in any form of conduct, or make any statements or representations, that disparage or otherwise impair the reputation,
goodwill, or commercial interests of the Bank, any Affiliates or any of their agents, officers, directors, employees and/or stockholders. The Bank agrees to not issue any press release or other statement that disparages or otherwise impairs the
Employee’s business reputation. The foregoing shall not be violated by: (i) truthful statements by either party in response to legal process or required governmental testimony or filings; (ii) statements by the officers or directors
of the Bank that they in good faith believe are necessary or appropriate to make in connection with performing their duties to the Bank or an Affiliate; or (iii) statements by the Employee that he in good faith believes are necessary or
appropriate to make to refute statements of the Bank, or the officers or directors of the Bank. 

  
 3 

 (b) Cooperation. The Employee agrees to reasonably assist and cooperate with the
Bank (and its outside counsel) in connection with the defense or prosecution of any claim that may be made or threatened against or by the Bank or any Affiliate, or in connection with any ongoing or future investigation or dispute or claim of any
kind involving the Bank or any Affiliate, including any proceeding before any arbitral, administrative, judicial, legislative, or other body or agency, including preparing for and testifying in any proceeding to the extent such claims,
investigations or proceedings relate to services performed by the Employee, pertinent knowledge possessed by the Employee, or any act or omission by the Employee. The Employee’s agreement under this Section 4(b) is limited such that any
assistance and cooperation shall not unreasonably interfere with the Employee’s subsequent employment. The Bank will reimburse the Employee for the reasonable out-of pocket expenses incurred as a result of such cooperation. 

(c) Nonsolicitation. Until the termination of the One-Year Term, the Employee shall not, directly or indirectly, without the
written consent of the Bank (i) initiate contact with or solicit any employee or customer of the Bank or any Affiliate; (ii) hire or otherwise engage any such employee or former employee; (iii) induce or otherwise counsel, advise or
encourage any such employee to leave the employment of the Bank or an Affiliate; or (iv) induce any supplier, licensor, licensee, business relation, representative or agent of the Bank to terminate or modify its relationship with the Bank or
any Affiliate, or in any way interfere with the relationship between the Bank or any Affiliate and such other party. 
 (d)
Return of Property. Immediately prior to the Employees Date of Termination, the Employee will return to the Bank (or destroy, upon written consent of the Bank) any and all files or other property (both tangible and intellectual) of the Bank
without retaining any copies or extracts thereof in any form or manner, including electronic or web-based. Notwithstanding the foregoing, the Employee has no duty with respect to any information that has been or is generally available to the public.

 (e) Reasonableness. The Employee acknowledges that the future conduct and obligation provisions of this Section 4
will not prevent him or her from obtaining other gainful employment or cause him or her any undue hardship and are reasonable and necessary in order to protect the legitimate interests of the Bank. 

5. Full Discharge. The Employee agrees and acknowledges that the payments and benefits provided in this Agreement are in full discharge
of any and all liabilities and obligations of the Bank to the Employee, monetarily or with respect to employee benefits or otherwise, including any and all obligations arising under any alleged written or oral employment agreement, policy, plan or
procedure of the Bank, or any Affiliate. 
 6. Certain Forfeitures in Event of Breach or Other Liability to the Bank. The
Employee acknowledges and agrees that, notwithstanding any other provision of this Agreement, if the Employee materially breaches any obligation under this Agreement, or there is a final determination by a court of competent jurisdiction or an
arbitrator, or an agreement by the Employee as part of a settlement, that the Employee is otherwise liable to the Bank or its Affiliates, the Bank retains the right to recoup any and all payments and benefits provided for in Section 3, any
damages suffered by the Bank or its Affiliates, plus reasonable attorneys’ fees incurred in connection with such recovery and, to the extent that such benefits have not been fully disbursed to the Employee, the Bank reserves its rights to stop
all future disbursements of such benefits, except to the extent that such action is prohibited by law or would result in the invalidation of the release provided by the Employee under this Agreement. 

  
 4 

 7. Attorneys’ Fees. In the event of a dispute arising out of this Agreement,
reasonable attorneys’ fees and costs to Employee resulting from such dispute shall be paid by Bank only if Employee prevails in such dispute. 
 8. No Assignments. 
 (a) This Agreement is personal to each of the parties
hereto, and neither party may assign or delegate any of its rights or obligations hereunder without first obtaining the written consent of the other party; provided, however, that the Bank shall require any successor or assign (whether direct
or indirect, by purchase, merger, consolidation, operation of law or otherwise) to all or substantially all of the business and/or assets of the Bank, by an assumption agreement in form and substance satisfactory to the Employee, to expressly assume
and agree to perform this Agreement in the same manner and to the same extent that the Bank would be required to perform it if no such succession or assignment had taken place. Failure of the Bank to obtain such an assumption agreement prior to the
effectiveness of any such succession or assignment shall be a breach of this Agreement and shall entitle the Employee to compensation and benefits from the Bank in the same amount and on the same terms that Employee would be entitled to hereunder if
an event of Involuntary Termination occurred. For purposes of implementing the provisions of this Section 8(a), the date on which any such succession becomes effective shall be deemed the Date of Termination. 

(b) This Agreement and all rights of the Employee hereunder shall inure to the benefit of and be enforceable by the Employee’s
personal and legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. In the event of the death of the Employee, unless otherwise provided herein, all amounts payable hereunder shall be paid to the
Employee’s devisee, legatee, or other designee or, if there be no such designee, to the Employee’s estate. 
 9.
Deferred Payments. If following a termination of the Employee, the aggregate payments to be made by the Bank under this Agreement and all other plans or arrangements maintained by the Company or any of the Consolidated Subsidiaries would
exceed the limitation on deductible compensation contained in Code Section 162(m) in any calendar year, any such amounts in excess of such limitation shall be mandatorily deferred (without interest) to a calendar year such that the amount to be
paid to the Employee in such calendar year, including deferred amounts, does not exceed such limitation, provided, however, that such deferral shall not extend past when the deferred amount must be paid pursuant to Section 409A.

 10. Regulatory Provisions. 
 (a) Temporary Suspension or Prohibition. If the Employee is suspended and/or temporarily prohibited from participating in the conduct of the Bank’s affairs by a notice served under
Section 8(e)(3) or (g)(1) of the FDIA, 12 U.S.C. Section 1818(e)(3) and (g)(1), the Bank’s obligations under this Agreement shall be suspended as of the date of service, unless stayed by appropriate proceedings. If the charges in the
notice are dismissed, the Bank may in its discretion (i) pay the Employee all or part of the compensation withheld while its obligations under this Agreement were suspended and (ii) reinstate in whole or in part any of its obligations
which were suspended. 
 (b) Permanent Suspension or Prohibition. If the Employee is removed and/or permanently
prohibited from participating in the conduct of the Bank’s affairs by an order issued under Section 8(e)(4) or (g)(l) of the FDIA, 12 U.S.C. Section 1818(e)(4) and (g)(1), all obligations of the Bank under this Agreement shall
terminate as of the effective date of the order, but vested rights of the contracting parties shall not be affected. 

  
 5 

 (c) Default of the Bank. If the Bank is in default (as defined in
Section 3(x)(l) of the FDIA), all obligations under this Agreement shall terminate as of the date of default, but this provision shall not affect any vested rights of the contracting parties. 

(d) Termination by Regulators. All obligations under this Agreement shall be terminated, except to the extent determined that
continuation of this Agreement is necessary for the continued operation of the Bank: (1) at the time the FDIC enters into an agreement to provide assistance to or on behalf of the Bank under the authority contained in Section 13(c) of the
FDIA; or (2) by the FDIC or the OCC, at the time either agency approves a supervisory merger to resolve problems related to operation of the Bank. Any rights of the parties that have already vested, however, shall not be affected by any such
action. 
 (e) Resumption of Payments. The payment of any amounts which are delayed on account of an event or
circumstance described in this Section 10 shall be paid as soon as the Bank reasonably anticipates that the payment will again be permissible. 
 11. Delivery of Notices. For the purposes of this Agreement, all notices and other communications to any party hereto shall be in writing and shall be deemed to have been duly given when delivered
or sent by certified mail, return receipt requested, postage prepaid, addressed as follows:

 13.

provision shall not affect the validity or enforceability of the other provisions hereof. 
 15. Effect on Employment Rights;
Other Agreements. This Agreement does not constitute a contract of employment or impose on the Bank any obligation to retain the Employee, to change the status of the Employee’s employment, or to change the Bank’s policies regarding
termination of employment. In addition, the parties to this Agreement agree that this Agreement shall supercede any pre-existing agreement related to severance benefits of the nature set forth in Section 3 of this Agreement, and any such
pre-existing agreement shall be deemed terminated, null and void upon execution of this Agreement. 

  
 6 

 16. Governing Law. This Agreement shall be governed by the laws of the State of
Texas to the extent that federal law does not govern. 
 17. Arbitration. Any dispute or controversy arising under or in
connection with this Agreement shall be settled exclusively by binding arbitration, conducted before a panel of three arbitrators in a location selected by the Employee within 100 miles of such Employee’s job location with the Bank, in
accordance with the rules of the American Arbitration Association then in effect. Judgment may be entered on the arbitrators’ award in any court having jurisdiction. 
 18. Tax Matters. The Bank may withhold from any amounts payable under this Agreement or otherwise such federal, state and local taxes as are required to be withheld pursuant to any applicable law
or regulation. The parties agree that the payments and benefits provided under this Agreement comply with Section 409A and, accordingly, this Agreement shall be interpreted to be in compliance therewith.

 FIRST AMENDED AND RESTATED AGREEMENT OF 

LIMITED PARTNERSHIP OF MPLX LP 
 THIS FIRST AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF MPLX LP dated as of October 31, 2012, is entered into by and between MPLX GP LLC, a Delaware limited liability company, as the
General Partner, and MPLX Logistics Holdings LLC, a Delaware limited liability company, together with any other Persons who become Partners in the Partnership or parties hereto as provided herein. In consideration of the covenants, conditions and
agreements contained herein, the parties hereto hereby agree as follows: 
 ARTICLE I 

DEFINITIONS 
 Section 1.1 Definitions. The following definitions shall be for all purposes, unless otherwise clearly indicated to the contrary, applied to the terms used in this Agreement.

 “Acquisition” means any transaction in which any Group Member acquires (through an asset acquisition,
stock acquisition, merger or other form of investment) control over all or a portion of the assets, properties or business of another Person for the purpose of increasing, over the long-term, the operating capacity or operating income of the
Partnership Group from the operating capacity or operating income of the Partnership Group existing immediately prior to such transaction. For purposes of this definition, “long-term” generally refers to a period of not less than twelve
months. 
 “Additional Book Basis” means the portion of any remaining Carrying Value of an Adjusted
Property that is attributable to positive adjustments made to such Carrying Value as a result of Book-Up Events. For purposes of determining the extent that Carrying Value constitutes Additional Book Basis: 

(a) Any negative adjustment made to the Carrying Value of an Adjusted Property as a result of either a Book-Down Event or a Book-Up Event
shall first be deemed to offset or decrease that portion of the Carrying Value of such Adjusted Property that is attributable to any prior positive adjustments made thereto pursuant to a Book-Up Event or Book-Down Event; and 

(b) If Carrying Value that constitutes Additional Book Basis is reduced as a result of a Book-Down Event and the Carrying Value of other
property is increased as a result of such Book-Down Event, an allocable portion of any such increase in Carrying Value shall be treated as Additional Book Basis; provided, that the amount treated as Additional Book Basis pursuant hereto as a result
of such Book-Down Event shall not exceed the amount by which the Aggregate Remaining Net Positive Adjustments after such Book-Down Event exceeds the remaining Additional Book Basis attributable to all of the Partnership’s Adjusted Property
after such Book-Down Event (determined without regard to the application of this clause (b) to such Book-Down Event). 

Table of Contents

 “Additional Book Basis Derivative Items” means any Book Basis
Derivative Items that are computed with reference to Additional Book Basis. To the extent that the Additional Book Basis attributable to all of the Partnership’s Adjusted Property as of the beginning of any taxable period exceeds the Aggregate
Remaining Net Positive Adjustments as of the beginning of such period (the “Excess Additional Book Basis”), the Additional Book Basis Derivative Items for such period shall be reduced by the amount that bears the same ratio to the amount
of Additional Book Basis Derivative Items determined without regard to this sentence as the Excess Additional Book Basis bears to the Additional Book Basis as of the beginning of such period. With respect to a Disposed of Adjusted Property, the
Additional Book Basis Derivative Items shall be the amount of Additional Book Basis taken into account in computing gain or loss from the disposition of such Disposed of Adjusted Property. 

“Adjusted Capital Account” means the Capital Account maintained for each Partner as of the end of each taxable
period of the Partnership, (a) increased by any amounts that such Partner is obligated to restore under the standards set by Treasury Regulation Section 1.704-1(b)(2)(ii)(c) (or is deemed obligated to restore under Treasury Regulation
Sections 1.704-2(g) and 1.704-2(i)(5)) and (b) decreased by (i) the amount of all losses and deductions that, as of the end of such taxable period, are reasonably expected to be allocated to such Partner in subsequent taxable periods
under Sections 704(e)(2) and 706(d) of the Code and Treasury Regulation Section 1.751-1(b)(2)(ii), and (ii) the amount of all distributions that, as of the end of such taxable period, are reasonably expected to be made to such Partner
in subsequent taxable periods in accordance with the terms of this Agreement or otherwise to the extent they exceed offsetting increases to such Partner’s Capital Account that are reasonably expected to occur during (or prior to) the taxable
period in which such distributions are reasonably expected to be made (other than increases as a result of a minimum gain chargeback pursuant to Section 6.1(d)(i) or 6.1(d)(ii)). The foregoing definition of Adjusted Capital
Account is intended to comply with the provisions of Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith. The “Adjusted Capital Account” of a Partner in respect of any Partnership Interest
shall be the amount that such Adjusted Capital Account would be if such Partnership Interest were the only interest in the Partnership held by such Partner from and after the date on which such Partnership Interest was first issued. 

“Adjusted Operating Surplus” means, with respect to any period, (a) Operating Surplus generated with respect
to such period less (b) (i) the amount of any net increase in Working Capital Borrowings (or the Partnership’s proportionate share of any net increase in Working Capital Borrowings in the case of Subsidiaries that are not wholly
owned) with respect to such period and (ii) the amount of any net decrease in cash reserves (or the Partnership’s proportionate share of any net decrease in cash reserves in the case of Subsidiaries that are not wholly owned) for Operating
Expenditures with respect to such period not relating to an Operating Expenditure made with respect to such period, and plus (c) (i) the amount of any net decrease in Working Capital Borrowings (or the Partnership’s proportionate
share of any net decrease in Working Capital Borrowings in the case of Subsidiaries that are not wholly owned) with respect to such period, (ii) the amount of any net decrease made in subsequent periods in cash reserves for Operating
Expenditures initially established with respect to such period to the extent such decrease results in a reduction in Adjusted Operating Surplus in subsequent periods pursuant to clause (b)(ii) above and (iii) the amount of any net
increase in cash reserves (or the Partnership’s proportionate share of any net increase in cash reserves in the case of Subsidiaries

that are not wholly owned) for Operating Expenditures with respect to such period required by any debt instrument for the repayment of principal, interest or premium. Adjusted Operating Surplus

intermediaries controls, is controlled by or is under common control with, the Person in question. As used herein, the term “control” means the possession, direct or indirect, of the power to direct or cause the direction of the management

asset at the time of contribution and in the case of an Adjusted Property, the fair market value of such Adjusted Property on the date of the revaluation event as described in Section 5.5(d), in both cases as determined by the General
Partner. The General Partner shall use such method as it determines to be appropriate to allocate the aggregate Agreed Value of Contributed Properties contributed to the Partnership in a single or integrated transaction among each separate property
on a basis proportional to the fair market value of each Contributed Property. 
 “Agreement” means this
First Amended and Restated Agreement of Limited Partnership of MPLX LP, as it may be amended, supplemented or restated from time to time. 
 “Associate” means, when used to indicate a relationship with any Person, (a) any corporation or organization of which such Person is a director, officer, manager, general
partner or managing member or is, directly or indirectly, the owner of 20% or more of any class of voting stock or other voting interest, (b) any trust or other estate in which such Person has at least a 20% beneficial interest or as to which

provided further, that disbursements made by a Group Member or cash reserves established, increased or reduced after the end of such Quarter but on or before the date of determination of Available Cash with respect to such Quarter shall be

Partnership pursuant to the agreements relating to such business activity, and (b) do anything necessary or appropriate to the foregoing, including the making of capital contributions or
loans to a Group Member; provided, however, that the General Partner shall not cause the Partnership to engage, directly or indirectly, in any business activity that the General Partner determines would be reasonably likely to cause the

Partner or such Affiliate or nominee for the use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, however, that the General Partner shall use reasonable efforts to cause record title to such assets
(other than those assets in respect of which the General Partner determines that the expense and difficulty of conveyancing makes transfer of record title to the Partnership impracticable) to be vested in the Partnership or one or more of the
Partnership’s designated Affiliates as soon as reasonably practicable; provided further, that, prior to the withdrawal or removal of the General Partner or as soon thereafter as practicable, the General Partner shall use reasonable
efforts to effect the transfer of record title to the Partnership and, prior to any such transfer, will provide for the use of such assets in a manner satisfactory to any successor General Partner. All Partnership assets shall be recorded as the

(b) The appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and the Transfer Agent shall

permitted by law, the Limited Partner shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate. 

(c) As a condition to the issuance of any new Certificate under this Section 4.2, the General Partner may require the payment

purported transfer.

stockholder, member, partner or other owner of the General Partner or any Limited Partner of any or all of such Person’s shares of stock, membership interests, partnership interests or other ownership interests in the General Partner or such
Limited Partner and the term “transfer” shall not include any such disposition.

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 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.

Rights. The General Partner or any other holder of Incentive Distribution Rights may transfer any or all of its Incentive Distribution Rights without the approval of any Limited Partner or any other Person. 

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 at least a majority of the Outstanding Limited Partner Interests of such class.

 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 

  
 34 

Table of Contents

 
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. 
 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, 

  
 35 

Table of Contents

 
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 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 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. 

  
 36 

Table of Contents

 (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.

General Partner Interests immediately prior to the issuance of such additional Limited Partner Interests by the Partnership by (y) 100% less the Percentage Interest with respect to the General Partner Interest immediately prior to the issuance
of such additional Limited Partner Interests by the Partnership times (B) the gross amount contributed to the Partnership by the Limited Partners (before deduction of underwriters’ discounts and commissions) in exchange for such additional
Limited Partner Interests. Any Capital Contribution pursuant to this Section 5.2(b) shall be evidenced by the issuance to the General Partner of a proportionate number of additional General Partner Units. 

Section 5.3 Contributions by Limited Partner. 
 (a) On the Closing Date, pursuant to and as described in the Contribution Agreement, MPLX Logistics Holdings contributed to the Partnership, as a Capital Contribution, all of MPLX Logistics Holdings’

(e) 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). The initial Capital Account balance attributable to the General Partner
Units issued to the General Partner pursuant to Section 5.2(a) shall equal the Net Agreed Value of the Capital Contribution specified in Section 5.2(a), which shall be deemed to equal the product of the number of General
Partner Units issued to the General Partner pursuant to Section 5.2(a) and the Initial Unit Price for each Common Unit (and the initial Capital Account balance attributable to each General Partner Unit shall equal the Initial Unit Price
for each Common Unit). The initial Capital Account balance attributable to the Common Units and Subordinated Units issued to MPLX Logistics Holdings pursuant to Section 5.3(a) shall equal the respective Net Agreed Value of the Capital
Contributions specified in Section 5.3(a), which shall be deemed to equal the product of the number of Common Units and Subordinated Units issued to MPLX Logistics Holdings pursuant to Section 5.3(a) and the Initial Unit Price for
each such Common Unit and Subordinated Unit (and the initial Capital Account balance attributable to each such Common Unit and Subordinated Unit shall equal its Initial Unit Price). The initial Capital Account balance attributable to the Common
Units issued to the IPO Underwriters pursuant to Section 5.3(b) shall equal the product of the number of Common Units so issued to the IPO Underwriters and the Initial Unit Price for each Common Unit (and the initial Capital Account
balance attributable to each such Common Unit shall equal its Initial Unit Price). The initial Capital Account attributable to the Incentive Distribution Rights shall be zero. Thereafter, the 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 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. 

(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 (x) any other Group Member that is classified as a partnership or disregarded entity for federal income tax purposes and (y) 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 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) Any income, gain or loss
attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Partnership’s Carrying Value with respect to such
property as of such date. 
 (v) 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). 

  
 40 

Table of Contents

 (vi) In accordance with the requirements of Section 704(b) of the Code, any deductions
for depreciation, cost recovery or amortization attributable to any Contributed Property shall be determined as if the adjusted basis of such property on the date it was acquired by the Partnership were equal to the Agreed Value of such property.
Upon an adjustment pursuant to Section 5.5(d) to the Carrying Value of any Partnership property subject to depreciation, cost recovery or amortization, any further deductions for such depreciation, cost recovery or amortization
attributable to such property shall be determined 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. 
 (vii) 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)(i) Except as otherwise provided in this Section 5.5(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. 
 (ii) Subject to Section 6.7(c), immediately prior to the transfer of a
Subordinated Unit or of a Subordinated Unit that has converted into a Common Unit pursuant to Section 5.7 by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this
subparagraph 5.5(c)(ii) apply), the Capital Account maintained for such Person with respect to its Subordinated Units or converted Subordinated Units will (A) first, be allocated to the Subordinated Units or converted Subordinated
Units to be transferred in an amount equal to the product of (x) the number of such Subordinated Units or converted Subordinated Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any
remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any converted Subordinated Units (“Retained Converted Subordinated Units”) or Subordinated Units. Following
any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Subordinated Units or Retained Converted Subordinated Units, if any, will have a balance equal to the amount allocated under
clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred Subordinated Units or converted Subordinated Units will have a balance equal to the amount allocated under
clause (A) hereinabove. 
 (iii) Subject to Section 6.8(b), immediately prior to the transfer of an IDR
Reset Common Unit by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.5(c)(iii) apply), the Capital Account maintained for such Person with respect to its IDR Reset Common Units
will (A) first, be allocated to the IDR Reset Common Units to be transferred in an amount equal to the product of (x) the number of such IDR Reset Common Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit,
and (B) second, any remaining balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any IDR Reset Common Units. Following any such allocation, the transferor’s Capital Account, if any,
maintained with 

  
 41 

Table of Contents

 
respect to the retained IDR Reset Common Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established
with respect to the transferred IDR Reset Common Units will have a balance equal to the amount allocated under clause (A) above. 
 (d)(i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on an issuance of additional Partnership Interests for cash or Contributed Property, the issuance of Partnership Interests
as consideration for the provision of services, or the conversion of the General Partner’s Combined Interest to Common Units pursuant to Section 11.3(b), the Capital Account of each Partner and the Carrying Value of each Partnership
property immediately prior to such issuance shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, and any such Unrealized Gain or Unrealized Loss shall be treated, for
purposes of maintaining Capital Accounts, as if it had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately prior to such issuance and had been allocated among the Partners at such time
pursuant to Section 6.1(c) and Section 6.1(d) in the same manner as any item of gain or loss actually recognized following an event giving rise to the dissolution of the Partnership would have been allocated; 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 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 Capital Accounts of all Partners and the Carrying Value of all Partnership property shall be adjusted
upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, and any such Unrealized Gain or Unrealized Loss shall be treated, for purposes of maintaining Capital Accounts, as if it had been
recognized on an actual sale of each such property immediately prior to such distribution for an amount equal to its fair market value, and had been allocated among the Partners, at such time, pursuant to Section 6.1(c) and
Section 6.1(d) in the same manner as any item of gain or loss actually recognized following an event giving rise to the dissolution of the Partnership would have been allocated. 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 

  
 42

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. 
 Section 5.6 Issuances of Additional Partnership Interests. 

(a) The Partnership may issue additional Partnership Interests (other than General Partner Interests (except for General Partner
Interests issued pursuant to Section 5.2(b))) 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
Units pursuant to the terms of this Agreement, (iii) the issuance of Common Units pursuant to Section 5.11, (iv) reflecting admission of such additional Limited Partners in the Partnership Register as the Record Holders of such
Limited Partner Interests and (v) 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 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 Units pursuant to the terms of this Agreement, including compliance
with any statute, rule, regulation or guideline of any federal, state or other governmental agency or any National Securities Exchange on which the Units or other Partnership Interests are listed or admitted to trading. 

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

the expiration of the Subordination Period. 
 (b) A Subordinated Unit that has converted into a Common Unit shall be subject to
the provisions of Section 6.7. 
 Section 5.8 Limited Preemptive Right. Except as provided in this
Section 5.8 and in Section 5.2 and Section 5.11 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. Other than with respect to the issuance of Partnership Interests in connection with the Initial Public Offering, 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), Section 6.6 and Section 6.9 (dealing with adjustments of distribution levels), 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 Unit basis (including any Common Unit Arrearage or Cumulative Common Unit Arrearage) or stated as a number of Units (including the number of Subordinated Units that may convert prior to the end of the Subordination
Period) are proportionately adjusted. 
 (b) Whenever such a distribution, subdivision or combination of Partnership 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) If a Pro Rata distribution of Partnership Interests, or a subdivision or combination of Partnership
Interests, is made as contemplated in this Section 5.9, the number of General Partner Units constituting the Percentage Interest of the General Partner (as determined immediately prior to the Record Date for such distribution,
subdivision or combination) shall be appropriately adjusted as of the date of payment of such distribution, or the effective date of such subdivision or combination, to maintain such Percentage Interest of the General Partner.

 (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 Units or fractional General Partner Units upon any distribution, subdivision or
combination of Units. If a distribution, subdivision or combination of Units would result in the issuance of fractional Units and General Partner Units but for the provisions of Section 5.6(d) and this Section 5.9(e), each
fractional Unit and General Partner Unit shall be rounded to the nearest whole Unit or General Partner Unit (with fractional Units or General Partner Units equal to or greater than a 0.5 Unit or General Partner Unit being rounded to the next
higher Unit or General 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 Issuance of Common Units in
Connection with Reset of Incentive Distribution Rights. 
 (a) Subject to the provisions of this Section 5.11,
the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right, at any time when there are
no Subordinated Units Outstanding and the Partnership has made a distribution pursuant to Section 6.4(b)(v) for each of the four most recently completed Quarters and the amount of each such distribution did not exceed Adjusted Operating
Surplus for such Quarter, to make an election (the “IDR Reset Election”) to cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e)
and, in connection therewith, the holder or holders of the Incentive Distribution Rights will become entitled to receive their respective proportionate share of a number of Common Units (the “IDR Reset Common Units”) derived
by dividing (i) the average amount of the aggregate cash distributions made by the Partnership for the two full Quarters immediately preceding the giving of the Reset Notice (as defined in Section 5.11(b)) in respect of the
Incentive Distribution Rights by (ii) the average of the cash distributions made by the Partnership in respect of each Common Unit for the two full Quarters immediately preceding the giving of the Reset Notice (the number of Common Units
determined by such quotient is referred to herein as the “Aggregate Quantity of IDR Reset Common Units”). If at the time of any IDR Reset Election the General Partner and its Affiliates are not the holders of a majority in
interest of the Incentive Distribution Rights, then the IDR Reset Election shall be subject to the prior written concurrence of the General Partner that the conditions described in the immediately preceding

  
 45 

Table of Contents

 
sentence have been satisfied. Upon the issuance of such IDR Reset Common Units, the Partnership will issue to the General Partner that number of additional General Partner Units equal to the
product of (x) the quotient obtained by dividing (A) the Percentage Interest of the General Partner immediately prior to such issuance by (B) a percentage equal to 100% less such Percentage Interest by (y) the number of such IDR
Reset Common Units, and the General Partner shall not be obligated to make any additional Capital Contribution to the Partnership in exchange for such issuance. The making of the IDR Reset Election in the manner specified in this
Section 5.11 shall cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e) and, in connection therewith, the holder or holders of the Incentive
Distribution Rights will become entitled to receive IDR Reset Common Units and the General Partner will become entitled to receive General Partner Units on the basis specified above, without any further approval required by the General Partner or
the Unitholders other than as set forth in this Section 5.11(a), at the time specified in Section 5.11(c) unless the IDR Reset Election is rescinded pursuant to Section 5.11(d). 

(b) To exercise the right specified in Section 5.11(a), the holder of the Incentive Distribution Rights (or, if there is more
than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall deliver a written notice (the “Reset Notice”) to the Partnership. Within 10 Business
Days after the receipt by the Partnership of such Reset Notice, the Partnership shall deliver a written notice to the holder or holders of the Incentive Distribution Rights of the Partnership’s determination of the Aggregate Quantity of IDR
Reset Common Units that each holder of Incentive Distribution Rights will be entitled to receive. 
 (c) The holder or holders
of the Incentive Distribution Rights will be entitled to receive the Aggregate Quantity of IDR Reset Common Units and the General Partner will be entitled to receive the related additional General Partner Units on the fifteenth Business Day after
receipt by the Partnership of the Reset Notice; provided, however, that the issuance of IDR Reset Common Units to the holder or holders of the Incentive Distribution Rights shall not occur prior to the approval of the listing or admission for
trading of such IDR Reset Common Units by the principal National Securities Exchange upon which the Common Units are then listed or admitted for trading if any such approval is required pursuant to the rules and regulations of such National
Securities Exchange. 
 (d) If the principal National Securities Exchange upon which the Common Units are
then traded has not approved the listing or admission for trading of the IDR Reset Common Units to be issued pursuant to this Section 5.11 on or before the 30th calendar day following the Partnership’s receipt of the Reset Notice and such approval is required by the
rules and regulations of such National Securities Exchange, then the holder of the Incentive Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive
Distribution Rights) shall have the right to either rescind the IDR Reset Election or elect to receive other Partnership Interests having such terms as the General Partner may approve, with the approval of the Conflicts Committee, that will provide
(i) the same economic value, in the aggregate, as the Aggregate Quantity of IDR Reset Common Units would have had at the time of the Partnership’s receipt of the Reset Notice, as determined by the General Partner, and (ii) for the
subsequent conversion of such Partnership Interests into Common Units within not more than 12 months following the Partnership’s receipt 

  
 46 

Table of Contents

 
of the Reset Notice upon the satisfaction of one or more conditions that are reasonably acceptable to the holder of the Incentive Distribution Rights (or, if there is more than one holder of the
Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights). 
 (e) The Minimum
Quarterly Distribution and the Target Distributions shall be adjusted at the time of the issuance of IDR Reset Common Units or other Partnership Interests pursuant to this Section 5.11 such that (i) the Minimum Quarterly
Distribution shall be reset to equal the average cash distribution amount per Common Unit for the two Quarters immediately prior to the Partnership’s receipt of the Reset Notice (the “Reset MQD”), (ii) the First
Target Distribution shall be reset to equal 115% of the Reset MQD, (iii) the Second Target Distribution shall be reset to equal 125% of the Reset MQD and (iv) the Third Target Distribution shall be reset to equal 150% of the Reset MQD.

 (f) Upon the issuance of IDR Reset Common Units pursuant to Section 5.11(a), the Capital Account maintained with
respect to the Incentive Distribution Rights will (i) first, be allocated to IDR Reset Common Units in an amount equal to the product of (A) the Aggregate Quantity of IDR Reset Common Units and (B) the Per Unit Capital Amount for an
Initial Common Unit, and (ii) second, as to any remaining balance in such Capital Account, will be retained by the holder of the Incentive Distribution Rights. If there is not sufficient capital associated with the Incentive Distribution Rights
to allocate the full Per Unit Capital Amount for an Initial Common Unit to the IDR Reset Common Units in accordance with clause (i) of this Section 5.11(f), the IDR Reset Common Units shall be subject to
Sections 6.1(d)(x)(B) and (C).

as the “First Liquidation Target Amount”); 
 (E) Fifth, (x) to the General Partner
in accordance with its Percentage Interest, (y) 13% to the holders of the Incentive Distribution Rights, Pro Rata, and (z) to all Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to

(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. 
 (A) If the amount of cash or the Net Agreed Value of any property distributed (except cash or property distributed pursuant to Section 12.4) with respect to a Unit exceeds the amount of cash
or the Net Agreed Value of property distributed with respect to another Unit (the amount of the excess, an “Excess Distribution” and the Unit with respect to which the greater distribution is paid, an “Excess
Distribution Unit”), then (1) 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 

  
 51 

Table of Contents

 
Distribution Unit pursuant to this Section 6.1(d)(iii)(A) for the current taxable period and all previous taxable periods is equal to the amount of the Excess Distribution; and
(2) the General Partner shall be allocated gross income and gain with respect to each such Excess Distribution in an amount equal to the product obtained by multiplying (aa) the quotient determined by dividing (x) the General
Partner’s Percentage Interest at the time when the Excess Distribution occurs by (y) a percentage equal to 100% less the General Partner’s Percentage Interest at the time when the Excess Distribution occurs, times (bb) the total
amount allocated in clause (1) above with respect to such Excess Distribution. 
 (B) After the
application of Section 6.1(d)(iii)(A), all or any portion of the remaining items of Partnership gross income or gain for the taxable period, if any, shall be allocated (1) to the holders of Incentive Distribution Rights, Pro Rata,
until the aggregate amount of such items allocated to the holders of Incentive Distribution Rights pursuant to this Section 6.1(d)(iii)(B) for the current taxable period and all previous taxable periods is equal to the cumulative amount
of all Incentive Distributions made to the holders of Incentive Distribution Rights from the Closing Date to a date 60 days after the end of the current taxable period; and (2) to the General Partner an amount equal to the product of
(aa) an amount equal to the quotient determined by dividing (x) the General Partner’s Percentage Interest by (y) the sum of 100 less the General Partner’s Percentage Interest times (bb) the sum of the amounts allocated
in clause (1) above. 
 (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.

Table of Contents

 (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. 

(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) At the election of the General Partner with respect to any
taxable period ending upon, or after, the termination of the Subordination Period, all or a portion of the remaining items of Partnership gross income or gain for such taxable period, after taking into account allocations pursuant to
Section 6.1(d)(iii), shall be allocated 100% to each Partner holding Subordinated Units that are Outstanding as of the termination of the Subordination Period (“Final Subordinated Units”) in the proportion of the
number of Final Subordinated Units held by such Partner to the total number of Final Subordinated Units then Outstanding, until each such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with
respect to such Final Subordinated Units to an amount that after taking into account the other allocations of income, gain, loss and deduction to be made with respect to such taxable period will equal the product of (1) the number of Final
Subordinated Units held by such Partner and (2) the Per Unit Capital Amount for a Common Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying Final Subordinated Units and the Capital Accounts
underlying Common Units held by Persons other than the General Partner and its Affiliates immediately prior to the conversion of 

  
 53 

Table of Contents

 
such Final Subordinated Units into Common Units. This allocation method for establishing such economic uniformity will be available to the General Partner only if the method for allocating the
Capital Account maintained with respect to the Subordinated Units between the transferred and retained Subordinated Units pursuant to Section 5.5(c)(ii) does not otherwise provide such economic uniformity to the Final Subordinated Units.

 (B) With respect to an event triggering an adjustment to the Carrying Value of Partnership property pursuant
to Section 5.5(d) during any taxable period of the Partnership ending upon, or after, the issuance of IDR Reset Common Units pursuant to Section 5.11, after the application of Section 6.1(d)(x)(A), any Unrealized
Gains and Unrealized Losses shall be allocated among the Partners in a manner that to the nearest extent possible results in the Capital Accounts maintained with respect to such IDR Reset Common Units issued pursuant to Section 5.11
equaling the product of (1) the Aggregate Quantity of IDR Reset Common Units and (2) the Per Unit Capital Amount for an Initial Common Unit. 
 (C) With respect to any taxable period during which an IDR Reset Common Unit is transferred to any Person who is not an Affiliate of the transferor, all or a portion of the remaining items of Partnership
gross income or gain for such taxable period shall be allocated 100% to the transferor Partner of such transferred IDR Reset Common Unit until such transferor Partner has been allocated an amount of gross income or gain that increases the Capital
Account maintained with respect to such transferred IDR Reset Common Unit to an amount equal to the Per Unit Capital Amount for an Initial Common Unit. 
 (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) 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 

  
 54 

Table of Contents

 
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)(xi)(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)(xi)(A) shall only be made with respect to Required Allocations to the extent the General Partner
determines that such allocations will otherwise be inconsistent with the economic agreement among the Partners. Further, allocations pursuant to this Section 6.1(d)(xi)(A) shall be deferred with respect to allocations pursuant to
clauses (1) and (2) hereof to the extent the General Partner determines that such allocations are likely to be offset by subsequent Required Allocations. 

(B) The General Partner shall, with respect to each taxable period, (1) apply the provisions of
Section 6.1(d)(xi)(A) in whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(d)(xi)(A)
among the Partners in a manner that is likely to minimize such economic distortions. 
 (xii) Corrective and Other
Allocations. In the event of any allocation of Additional Book Basis Derivative Items or any Book-Down Event or any recognition of a Net Termination Loss, the following rules shall apply: 

(A) Except as provided in Section 6.1(d)(xii)(B), in the case of any allocation of Additional Book Basis
Derivative Items (other than an allocation of Unrealized Gain or Unrealized Loss under Section 5.5(d) hereof), the General Partner shall allocate such Additional Book Basis Derivative Items to (1) the holders of Incentive
Distribution Rights and the General Partner to the same extent that the Unrealized Gain or Unrealized Loss giving rise to such Additional Book Basis Derivative Items was allocated to them pursuant to Section 5.5(d) and (2) all
Unitholders, Pro Rata, to the extent that the Unrealized Gain or Unrealized Loss giving rise to such Additional Book Basis Derivative Items was allocated to any Unitholders pursuant to Section 5.5(d). 

(B) In the case of any allocation of Additional Book Basis Derivative Items (other than an allocation of Unrealized Gain
or Unrealized Loss under Section 5.5(d) hereof or an allocation of Net Termination Gain or Net Termination Loss pursuant to Section 6.1(c) hereof) as a result of a sale or other taxable disposition of any Partnership asset
that is an Adjusted Property (“Disposed of Adjusted Property”), the General Partner shall allocate (1) additional items of gross income and gain (aa) away from the holders of Incentive Distribution Rights and
(bb) to the Unitholders, or (2) additional items of deduction and loss (aa) away from the Unitholders and (bb) to the 

  
 55 

Table of Contents

 
holders of Incentive Distribution Rights, to the extent that the Additional Book Basis Derivative Items allocated to the Unitholders exceed their Share of Additional Book Basis Derivative Items
with respect to such Disposed of Adjusted Property. Any allocation made pursuant to this Section 6.1(d)(xii)(B) shall be made after all of the other Agreed Allocations have been made as if this Section 6.1(d)(xii) were not in
this Agreement and, to the extent necessary, shall require the reallocation of items that have been allocated pursuant to such other Agreed Allocations. 
 (C) In the case of any negative adjustments to the Capital Accounts of the Partners resulting from a Book-Down Event or from the recognition of a Net Termination Loss, such negative adjustment
(1) shall first be allocated, to the extent of the Aggregate Remaining Net Positive Adjustments, in such a manner, as determined by the General Partner, that to the extent possible the aggregate Capital Accounts of the Partners will equal the
amount that would have been the Capital Account balances of the Partners if no prior Book-Up Events had occurred, and (2) any negative adjustment in excess of the Aggregate Remaining Net Positive Adjustments shall be allocated pursuant to
Section 6.1(c) hereof. 
 (D) For purposes of this Section 6.1(d)(xii), the Unitholders
shall be treated as being allocated Additional Book Basis Derivative Items to the extent that such Additional Book Basis Derivative Items have reduced the amount of income that would otherwise have been allocated to the Unitholders under this
Agreement. In making the allocations required under this Section 6.1(d)(xii), the General Partner may apply whatever conventions or other methodology it determines will satisfy the purpose of this Section 6.1(d)(xii). Without
limiting the foregoing, if an Adjusted Property is contributed by the Partnership to another entity classified as a partnership for federal income tax purposes (the “lower tier partnership”), the General Partner may make
allocations similar to those described in Sections 6.1(d)(xii)(A) through (C) to the extent the General Partner determines such allocations are necessary to account for the Partnership’s allocable share of income, gain,
loss and deduction of the lower tier partnership that relate to the contributed Adjusted Property in a manner that is consistent with the purpose of this Section 6.1(d)(xii). 

(xiii) Special Curative Allocation in Event of Liquidation Prior to End of Subordination Period. Notwithstanding any other
provision of this Section 6.1 (other than the Required Allocations), if the Liquidation Date occurs prior to the conversion of the last Outstanding Subordinated Unit, then items of income, gain, loss and deduction for the taxable period
that includes the Liquidation Date (and, if necessary, items arising in previous taxable periods to the extent the General Partner determines such items may be so allocated), shall be specially allocated among the Partners in the manner determined
appropriate by the General Partner so as to cause, to the maximum extent possible, the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior allocations of Net Termination Gain and Net
Termination Loss had been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable. 

Section 6.2 Allocations for Tax Purposes. 

  
 56 

Table of Contents

 (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 

  
 57 

Table of Contents

 
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 such items for the period beginning on the Closing Date and ending on the last day of the month in which the last Option Closing Date or the expiration of the Over-Allotment Option occurs 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 next succeeding month; provided further, 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. 
 Section 6.3 Requirement and
Characterization of Distributions; Distributions to Record Holders. 
 (a) Within 60 days following the end of each
Quarter commencing with the Quarter ending on December 31, 2012, 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 to the Partners as of
the Record Date selected by the General Partner. The Record Date for the first distribution of Available Cash shall not be prior to the final closing of the Over-Allotment Option. 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 Partners pursuant to Section 6.4 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, except as otherwise provided in Section 6.5, be deemed to be “Capital
Surplus.” 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) The General Partner may treat taxes paid by the Partnership on behalf of, or amounts withheld
with respect to, all or less than all of the Partners, as a distribution of 

  
 58 

Table of Contents

 
Available Cash to such Partners, as determined appropriate under the circumstances by the General Partner. 
 (d) Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through the Transfer Agent or through any other Person or agent, only to the Record Holder of such
Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in respect of such payment, regardless of any claim of any Person who may have an
interest in such payment by reason of an assignment or otherwise. 
 Section 6.4 Distributions of Available Cash from
Operating Surplus. 
 (a) During the Subordination Period. Available Cash with respect to any Quarter within the
Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or 6.5 shall be distributed as follows, except as otherwise required in respect of additional Partnership Interests issued

 (iii) Third, (x) to the
General Partner in accordance with its Percentage Interest and (y) to the Unitholders holding Subordinated Units, Pro Rata, a percentage equal to 100% less the General Partner’s Percentage Interest, until there has been distributed in
respect of each Subordinated Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter; 

(iv) Fourth, to the General Partner and all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then
Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter; 
 (v) Fifth, (A) to the General Partner in accordance with its Percentage Interest, (B) 13% to the holders of the Incentive Distribution Rights, Pro Rata, and (C) to all Unitholders, Pro
Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (A) and (B) of this clause (v), until there has been distributed in respect of each Unit then Outstanding an amount equal
to the excess of the Second Target Distribution over the First Target Distribution for such Quarter; 
 (vi) Sixth, (A) to
the General Partner in accordance with its Percentage Interest, (B) 23% to the holders of the Incentive Distribution Rights, Pro Rata, and (C) to all

been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and 

(vii) Thereafter, (A) to the General Partner in accordance with its Percentage Interest, (B) 48% to the holders of the
Incentive Distribution Rights, Pro Rata, and (C) to all Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (A) and (B) of this clause (vii); 

provided, however, that if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third Target
Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with
Section 6.4(a)(vii). 
 (b) After the Subordination Period. Available Cash with respect to any Quarter after
the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or Section 6.5 shall be distributed as follows, except as otherwise required in respect of additional Partnership

 (ii) Second, to the General Partner and all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution
over the Minimum Quarterly Distribution for such Quarter; 
 (iii) Third, (A) to the General Partner in accordance with
its Percentage Interest, (B) 13% to the holders of the Incentive Distribution Rights, Pro Rata, and (C) to all Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (A) and

 (iv) Fourth, (A) to the General Partner in accordance with its Percentage Interest, (B) 23% to the holders of the
Incentive Distribution Rights, Pro Rata, and (C) to all Unitholders, Pro Rata, a percentage equal to 100% less the sum of the percentages applicable to subclauses (A) and (B) of this clause (iv), until there
has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and

 60 

Table of Contents

 provided, however, that if the Minimum Quarterly Distribution, the First Target Distribution, the
Second Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any
Quarter will be made solely in accordance with Section 6.4(b)(v). 
 Section 6.5 Distributions of Available
Cash from Capital Surplus. Available Cash that is deemed to be Capital Surplus pursuant to the provisions of Section 6.3(a) shall be distributed, unless the provisions of Section 6.3 require otherwise, to the General
Partner and the Unitholders, Pro Rata, until a hypothetical holder of a Common Unit acquired on the Closing Date has received with respect to such Common Unit distributions of Available Cash that are deemed to be Capital Surplus in an aggregate
amount equal to the Initial Unit Price. Available Cash that is deemed to be Capital Surplus shall then be distributed (A) to the General Partner in accordance with its Percentage Interest and (B) to all Unitholders holding Common Units,
Pro Rata, a percentage equal to 100% less the General Partner’s Percentage Interest, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage. Thereafter, all
Available Cash shall be distributed as if it were Operating Surplus and shall be distributed in accordance with Section 6.4. 
 Section 6.6 Adjustment of Minimum Quarterly Distribution and Target Distribution Levels. 
 (a) The Minimum Quarterly Distribution, Target Distributions, Common Unit Arrearages and Cumulative Common Unit Arrearages shall be proportionately adjusted in the event of any distribution, combination
or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Partnership Interests in accordance with Section 5.9. In the event of a distribution of Available Cash that is deemed to be from Capital
Surplus, the then applicable Minimum Quarterly Distribution and Target Distributions shall be adjusted proportionately downward to equal the product obtained by multiplying the otherwise applicable Minimum Quarterly Distribution, First Target
Distribution, Second Target Distribution and Third Target Distribution, as the case may be, by a fraction, the numerator of which is the Unrecovered Initial Unit Price of the Common Units immediately after giving effect to such distribution and the
denominator of which is the Unrecovered Initial Unit Price of the Common Units immediately prior to giving effect to such distribution. 
 (b) The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall also be subject to adjustment pursuant to Section 5.11 and
Section 6.9. 
 Section 6.7 Special Provisions Relating to the Holders of Subordinated Units.

 (a) Except with respect to the right to vote on or approve matters requiring the vote or approval of a percentage of the
holders of Outstanding Common Units and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units, the holder of a Subordinated Unit shall have all of the rights and obligations
of a Unitholder holding Common Units hereunder; provided, however, that immediately upon the conversion of Subordinated Units into Common Units pursuant to Section 5.7, the Unitholder

  
 61 

Table of Contents

 
holding a Subordinated Unit shall possess all of the rights and obligations of a Unitholder holding Common Units hereunder with respect to such converted Subordinated Units, including the right
to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and distributions made with respect to Common Units; provided, however, that such converted Subordinated Units shall remain subject
to the provisions of Sections 5.5(c)(ii), 6.1(d)(x)(A), 6.7(b) and 6.7(c). 
 (b) A Unitholder
shall not be permitted to transfer a Subordinated Unit or a Subordinated Unit that has converted into a Common Unit pursuant to Section 5.7 (other than a transfer to an Affiliate) if the remaining balance in the transferring
Unitholder’s Capital Account with respect to the retained Subordinated Units or Retained Converted Subordinated Units would be negative after giving effect to the allocation under Section 5.5(c)(ii)(B). 

(c) The holder of a Common Unit that has resulted from the conversion of a Subordinated Unit pursuant to Section 5.7 or
Section 11.4 shall not be issued a Common Unit Certificate pursuant to Section 4.1 (if the Common Units are represented by Certificates) and shall not be permitted to transfer such Common Unit to a Person that is not an
Affiliate of the holder until such time as the General Partner determines, based on advice of counsel, that each such Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in all material
respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this Section 6.7(c), the General Partner may take whatever steps are required to provide
economic uniformity to such Common Units in preparation for a transfer of such Common Units, including the application of Sections 5.5(c)(ii), 6.1(d)(x) and 6.7(b); provided, however, that no such steps may be taken that
would have a material adverse effect on the Unitholders holding Common Units. 
 Section 6.8 Special Provisions Relating
to the Holders of Incentive Distribution Rights. 
 (a) Notwithstanding anything to the contrary set forth in this
Agreement, the holders of the Incentive Distribution Rights (1) shall (x) possess the rights and obligations provided in this Agreement with respect to a Limited Partner pursuant to Article III and Article VII and
(y) have a Capital Account as a Partner pursuant to Section 5.5 and all other provisions related thereto and (2) shall not (x) be entitled to vote on any matters requiring the approval or vote of the holders of Outstanding
Units, except as provided by law, (y) be entitled to any distributions other than as provided in Sections 6.4(a)(v), (vi) and (vii), Sections 6.4(b)(iii), (iv) and (v), and
Section 12.4 or (z) be allocated items of income, gain, loss or deduction other than as specified in this Article VI; provided, however, that for the avoidance of doubt, the foregoing shall not preclude the Partnership
from making any other payments or distributions in connection with other actions permitted by this Agreement. 
 (b) A
Unitholder shall not be permitted to transfer an IDR Reset Common Unit (other than a transfer to an Affiliate) if the remaining balance in the transferring Unitholder’s Capital Account with respect to the retained IDR Reset Common Units would
be negative after giving effect to the allocation under Section 5.5(c)(iii). 

  
 62 

Table of Contents

 (c) A holder of an IDR Reset Common Unit that was issued in connection with an IDR Reset
Election pursuant to Section 5.11 shall not be issued a Common Unit Certificate pursuant to Section 4.1 (if the Common Units are evidenced by Certificates) or evidence of the issuance of uncertificated Common Units, and shall
not be permitted to transfer such Common Unit to a Person that is not an Affiliate of such holder, until such time as the General Partner determines, based on advice of counsel, that each such IDR Reset Common Unit should have, as a substantive
matter, like intrinsic economic and federal income tax characteristics, in all material respects, to the intrinsic economic and federal income tax characteristics of an Initial Common Unit. In connection with the condition imposed by this
Section 6.8(c), the General Partner may take whatever steps are required to provide economic uniformity to such IDR Reset Common Units in preparation for a transfer of such IDR Reset Common Units, including the application of
Section 5.5(c)(iii), Section 6.1(d)(x)(B), or Section 6.1(d)(x)(C); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units. 

Section 6.9 Entity-Level Taxation. If legislation is enacted or the official interpretation of existing legislation is
modified by a governmental authority, which after giving effect to such enactment or modification, results in a Group Member becoming subject to federal, state or local or non-U.S. income or withholding taxes in excess of the amount of such taxes
due from the Group Member prior to such enactment or modification (including, for the avoidance of doubt, any increase in the rate of such taxation applicable to the Group Member), then the General Partner may, at its option, reduce the Minimum
Quarterly Distribution and the Target Distributions by the amount of income or withholding taxes that are payable by reason of any such new legislation or interpretation (the “Incremental Income Taxes”), or any portion
thereof selected by the General Partner, in the manner provided in this Section 6.9. If the General Partner elects to reduce the Minimum Quarterly Distribution and the Target Distributions for any Quarter with respect to all or a portion
of any Incremental Income Taxes, the General Partner shall estimate for such Quarter the Partnership Group’s aggregate liability (the “Estimated Incremental Quarterly Tax Amount”) for all (or the relevant portion of)
such Incremental Income Taxes; provided that any difference between such estimate and the actual liability for Incremental Income Taxes (or the relevant portion thereof) for such Quarter may, to the extent determined by the General Partner, be taken
into account in determining the Estimated Incremental Quarterly Tax Amount with respect to each Quarter in which any such difference can be determined. For each such Quarter, the Minimum Quarterly Distribution, First Target Distribution, Second
Target Distribution and Third Target Distribution, shall be the product obtained by multiplying (a) the amounts therefor that are set out herein prior to the application of this Section 6.9 times (b) the quotient obtained by
dividing (i) Available Cash with respect to such Quarter by (ii) the sum of Available Cash with respect to such Quarter and the Estimated Incremental Quarterly Tax Amount for such Quarter, as determined by the General Partner. For purposes
of the foregoing, Available Cash with respect to a Quarter will be deemed reduced by the Estimated Incremental Quarterly Tax Amount for that Quarter.

(vi) the distribution of Partnership cash; 
 (vii) the selection and dismissal of officers, employees, agents, internal and outside attorneys, accountants, consultants and contractors and the determination of their compensation and other terms of

 (b) Notwithstanding any other provision of
this Agreement, any Group Member Agreement, the Delaware Act or any applicable law, rule or regulation, each Record Holder and each other Person who may acquire an interest in a Partnership Interest or that is otherwise bound by this Agreement
hereby (i) approves, ratifies and confirms the execution, delivery and performance by the parties thereto of this Agreement and the Group Member Agreement of each other Group Member, the IPO Underwriting Agreement, the Omnibus Agreement, the
Contribution Agreement, the Employee Services Agreements, and the other agreements described in or filed as exhibits to the IPO Registration Statement that are related to the transactions contemplated by the IPO Registration Statement (collectively,

Table of Contents

 
of any of them of this Agreement or any agreement authorized or permitted under this Agreement (including the exercise by the General Partner or any Affiliate of the General Partner of the rights
accorded pursuant to Article XV) shall not constitute a breach by the General Partner of any duty that the General Partner may owe the Partnership or the Limited Partners or any other Persons under this Agreement (or any other
agreements) or of any duty existing at law, in equity or otherwise. 
 Section 7.2 Certificate of Limited
Partnership. The General Partner has caused the Certificate of Limited Partnership to be filed with the Secretary of State of the State of Delaware as required by the Delaware Act. The General Partner shall use all reasonable efforts to cause to
be filed such other certificates or documents that the General Partner determines to be necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners
have limited liability) in the State of Delaware or any other state in which the Partnership may elect to do business or own property. To the extent the General Partner determines such action to be necessary or appropriate, the General Partner shall
file amendments to and restatements of the Certificate of Limited Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the
laws of the State of Delaware or of any other state in which the Partnership may elect to do business or own property. Subject to the terms of Section 3.3(a), the General Partner shall not be required, before or after filing, to deliver
or mail a copy of the Certificate of Limited Partnership, any qualification document or any amendment thereto to any Limited Partner. 
 Section 7.3 Restrictions on the General Partner’s Authority to Sell Assets of the Partnership Group. 
 Except as provided in Article XII and Article XIV, the General Partner may not sell, exchange or otherwise dispose of all or substantially all of the assets of the Partnership
Group, taken as a whole, in a single transaction or a series of related transactions (including by way of merger, consolidation or other combination or sale of ownership interests of the Partnership’s Subsidiaries) without the approval of
holders of a Unit Majority; provided, however, that this provision shall not preclude or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the
Partnership Group and shall not apply to any forced sale of any or all of the assets of the Partnership Group pursuant to the foreclosure of, or other realization upon, any such encumbrance. 

Section 7.4 Reimbursement of and Other Payments to the General Partner. 

(a) Except as provided in this Section 7.4, and elsewhere in this Agreement or in the Omnibus Agreement, the General Partner
shall not be compensated for its services as a general partner or managing member of any Group Member. 
 (b) Except as may be
otherwise provided in the Omnibus Agreement, the General Partner shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine, for (i) all direct and indirect expenses it incurs or payments it makes on behalf
of the Partnership Group (including salary, bonus, incentive compensation and other amounts paid to any Person, including Affiliates of the General Partner, to perform services for 

  
 66 

Table of Contents

 
the Partnership Group or for the General Partner in the discharge of its duties to the Partnership Group), and (ii) all other expenses allocable to the Partnership Group or otherwise
incurred by the General Partner or its Affiliates in connection with managing and operating the Partnership Group’s business and affairs (including expenses allocated to the General Partner by its Affiliates). The General Partner shall
determine the expenses that are allocable to the Partnership Group. Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to
Section 7.7. 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. 
 (c) The General Partner, without the approval of the Limited Partners (who shall have no right to vote in
respect thereof), may propose and adopt on behalf of the Partnership employee benefit plans, employee programs and employee practices (including plans, programs and practices involving the issuance of Partnership Interests or Derivative Partnership
Interests), or cause the Partnership to issue Partnership Interests or Derivative Partnership 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. Expenses incurred by the General Partner in connection with any such plans, programs and practices (including the net cost to the General Partner or such Affiliates of
Partnership Interests purchased by the General Partner or such Affiliates from the Partnership to fulfill options or awards under such plans, programs and practices) shall be reimbursed in accordance with Section 7.4(b). Any and all
obligations of the General Partner under any employee benefit plans, employee programs or employee practices adopted by the General Partner as permitted by this Section 7.4(c) shall constitute obligations of the General Partner
hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or Section 11.2 or the transferee of or successor to all of the General Partner’s General Partner Interest 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. 
 (e) The General Partner and its Affiliates
may enter into an agreement to provide services to any Group Member for a fee or otherwise than for cost.

 Section 7.5 Outside Activities. 

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

(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 

  
 68 

Table of Contents

 
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 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 Units and/or other Partnership Interests acquired by them. The term “Affiliates” when used in this
Section 7.5(d) with respect to the General Partner shall not include any Group Member. 
 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 (i) 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 or (ii) hasten the expiration of the Subordination Period or the conversion of any Subordinated Units into Common Units. 

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, 

  
 69 

Table of Contents

 
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 Outstanding 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 

  
 70 

Table of Contents

 
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. 

  
 71 

Table of Contents

 (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 Outstanding Common Units (excluding Common Units owned by the General Partner and its Affiliates), (iii) on terms no less
favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iv) fair and reasonable to the Partnership, taking into account the totality of the relationships between the parties involved
(including other transactions that may be particularly favorable or advantageous to the Partnership). The General Partner shall be authorized but not required in connection with its resolution of such conflict of interest to seek Special Approval 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 

  
 72 

Table of Contents

 
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, 

  
 73 

Table of Contents

 
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

  
 74 

Table of Contents

 
Interests; provided that, except as permitted pursuant to Section 4.10, the General Partner may not cause any Group Member to purchase Subordinated Units during the Subordination
Period. 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 

  
 76 

Table of Contents

 
Registrable Securities covered by such Registration Statement; provided, however, that the Partnership will not have any obligation to provide any document pursuant to
clause (B) 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.

Table of Contents

 (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 

  
 78 

Table of Contents

 
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.

TAX MATTERS 
 Section 9.1 Tax Returns and Information. The Partnership shall timely file all returns of the Partnership that are required for federal, state and local income tax purposes on the basis of the
accrual method and the taxable period or year that it is required by law to adopt, from time to time, as determined by the General Partner. In the event the Partnership is required to use a taxable period other than a year ending on
December 31, the General Partner shall use reasonable efforts to change the taxable period of the Partnership to a year ending on December 31. The tax information reasonably required by Record Holders for federal, state and local income
tax reporting purposes with respect to a taxable period shall be furnished to them within 90 days of the close of the calendar year in which the Partnership’s taxable period ends. The classification, realization and recognition of income,
gain, losses and deductions and other items shall be on the accrual method of accounting for federal income tax purposes.

 (a) The Partnership shall make the election under Section 754 of the Code in accordance with applicable regulations thereunder, subject to the reservation of the right to seek to revoke any such
election upon the General Partner’s determination that such revocation is in the best interests of the Limited Partners. Notwithstanding any other provision herein contained, for the purposes of computing the adjustments under
Section 743(b) of the Code, the General Partner shall be authorized (but not required) to adopt a convention whereby the price paid by a transferee of a Limited Partner Interest will be deemed to be the lowest quoted closing price of the
Limited Partner Interests on any National Securities Exchange on which such Limited Partner Interests are listed or admitted to trading during the calendar month in which such transfer is deemed to occur pursuant to Section 6.2(f)
without regard to the actual price paid by such transferee. 
 (b) Except as otherwise provided herein, the General Partner
shall determine whether the Partnership should make any other elections permitted by the Code. 
 Section 9.3 Tax
Controversies. Subject to the provisions hereof, the General Partner is designated as the “tax matters partner” (as defined in Section 6231(a)(7) of the Code) and is authorized and required to represent the Partnership (at the
Partnership’s expense) in connection with all examinations of the Partnership’s affairs by tax authorities, including resulting administrative and judicial proceedings, and to expend Partnership funds for professional services and costs
associated therewith. Each Partner agrees to cooperate with the General Partner and to do or refrain from doing any or all things reasonably required by the General Partner to conduct such proceedings. 

Section 9.4 Withholding. Notwithstanding any other provision of this Agreement, the General Partner is authorized to take any
action that may be required to cause the Partnership and other Group Members to comply with any withholding requirements established under the Code 

  
 81 

Table of Contents

 
or any other federal, state or local law including pursuant to Sections 1441, 1442, 1445 and 1446 of the Code, or established under any foreign law. To the extent that the Partnership is
required or elects to withhold and pay over to any taxing authority any amount resulting from the allocation or distribution of income to any Partner (including by reason of Section 1446 of the Code), the General Partner may treat the amount
withheld as a distribution of cash pursuant to Section 6.3 or Section 12.4(c) in the amount of such withholding from such Partner.

and (iv) shall be deemed to make any consents, acknowledgements or waivers contained in this Agreement, all with or without execution of this Agreement by such Person. The transfer of any Limited Partner Interests and the admission of any new
Limited Partner shall not constitute an amendment to this Agreement. A Person may become a Limited Partner without the consent or approval of any of the Partners. A Person may not become a Limited Partner without acquiring a Limited Partner Interest
and becoming the Record Holder of such Limited Partner Interest. The rights and obligations of a Person who is an Ineligible Holder shall be determined in accordance with Section 4.9. 

(c) With respect to any Limited Partner that holds Units representing Limited Partner Interests for another Person’s account (such

any matter, and unless the arrangement between such Persons provides otherwise, take all action as a Limited Partner by virtue of being the Record Holder of such Units at the

(d) The name and mailing address of each Record Holder shall be listed on the books of the Partnership maintained for such purpose by the
Partnership or the Transfer Agent. The General Partner shall update the books of the Partnership from time to time as necessary to reflect accurately the information therein (or shall cause the Transfer Agent to do so, as applicable). 

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

 Section 10.2 Admission of Successor General Partner. A 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 Interest pursuant to Section 4.6 who is proposed to be admitted as a successor General Partner shall be admitted to the
Partnership as the General Partner, effective immediately prior to the withdrawal or removal of the predecessor or transferring General Partner, pursuant to Section 11.1 or 11.2 or the transfer of the General Partner Interest
pursuant to Section 4.6; provided, however, that no such successor shall be admitted to the Partnership until compliance with the terms of Section 4.6 has occurred and such successor has executed and delivered such
other documents or instruments as may be required to effect such admission. Any such successor is hereby authorized to and shall, subject to the terms hereof, carry on the business of the members of the Partnership Group without dissolution.

 Section 10.3 Amendment of Agreement and Certificate of Limited Partnership. To effect the admission to the
Partnership of any Partner, the General Partner shall take all steps necessary or appropriate under the Delaware Act to amend the records of the Partnership to reflect such admission and, if necessary, to prepare as soon as practicable an amendment

shall result in the withdrawal of the General Partner from the Partnership. 
 (b) Withdrawal of the General Partner from the
Partnership upon the occurrence of an Event of Withdrawal shall not constitute a breach of this Agreement under the following circumstances: (i) at any time during the period beginning on the Closing Date and ending at 12:00 midnight,
Eastern Time, on December 31, 2022 the General Partner voluntarily withdraws by giving at least 90 days’ advance notice of its intention to withdraw to the Limited Partners; provided, that prior to the effective date of such
withdrawal, the withdrawal is approved by Unitholders holding at least a majority of the Outstanding Common Units (excluding Common Units owned by the General Partner and its Affiliates) and the General Partner delivers to the Partnership an Opinion
of Counsel (“Withdrawal Opinion of Counsel”) that such withdrawal (following the selection of the successor General Partner) would not result in the loss of the limited liability under the Delaware Act of any Limited Partner
or cause any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed); (ii) at any time after

record or control at least 50% of the Outstanding Units. The withdrawal of the General Partner from the Partnership upon the occurrence of an Event of Withdrawal shall also constitute the withdrawal of the General Partner as general partner or
managing member, if any, to the extent applicable, of the other Group Members. If the General Partner gives a notice of withdrawal pursuant to Section 11.1(a)(i), the holders of a Unit Majority, may, prior to the effective date of such
withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor general partner or managing member, to the extent applicable, of the other Group Members of which the General
Partner is a general partner or a managing member. If, prior to the effective date of the General Partner’s withdrawal, a successor is not elected by the Unitholders as provided herein or the Partnership does not receive a Withdrawal Opinion of
Counsel, the Partnership shall be dissolved in accordance with Section 12.1 unless the business of the Partnership is continued pursuant to Section 12.2. Any successor General Partner elected in accordance with the terms of
this Section 11.1 shall be subject to the provisions of Section 10.2. 
 Section 11.2 Removal of
the General Partner. The General Partner may be removed if such removal is approved by the Unitholders holding at least 66 2/3% of the Outstanding Units (including Units held by the General Partner and its Affiliates) voting as a single class.
Any such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a majority of the outstanding Common Units voting as a class and Unitholders holding a
majority of the outstanding Subordinated Units (if any Subordinated Units are then Outstanding) voting as a class (including, in each case, Units held by the General Partner and its Affiliates). Such removal shall be effective immediately following
the admission of a successor General Partner pursuant to Section 10.2. The removal of the General Partner shall also automatically constitute the removal of the General Partner as general partner or managing member, to the extent
applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If a Person is elected as a successor General Partner in accordance with the terms of this Section 11.2, such Person shall,
upon admission pursuant to Section 10.2, automatically become a successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member.
The right of the holders of Outstanding Units to remove the General Partner shall not exist or be exercised unless the Partnership has received an opinion opining as to the matters covered by a Withdrawal Opinion of Counsel. Any successor General
Partner elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.2. 
 Section 11.3 Interest of Departing General Partner and Successor General Partner. 
 (a) In the event of (i) withdrawal of the General Partner under circumstances where such withdrawal does not violate this Agreement or (ii) removal of the General Partner by the holders of
Outstanding Units under circumstances where Cause does not exist, if the successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2, the Departing General Partner shall have the option,
exercisable prior to the 

  
 85 

Table of Contents

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

For purposes of this Section 11.3(a), the fair market value of the Combined Interest shall be determined by agreement between the Departing
General Partner and its successor or, failing agreement within 30 days after the effective date of such Departing General Partner’s withdrawal or removal, by an independent investment banking firm or other independent expert selected by
the Departing General Partner and its successor, which, in turn, may rely on other experts, and the determination of which shall be conclusive as to such matter. If such parties cannot agree upon one independent investment banking firm or other
independent expert within 45 days after the effective date of such withdrawal or removal, then the Departing General Partner shall designate an independent investment banking firm or other independent expert, the Departing General
Partner’s successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a third independent investment banking firm or independent expert, which third independent
investment banking firm or other independent expert shall determine the fair market value of the Combined Interest. In making its determination, such third independent investment banking firm or other independent expert may consider the then current
trading price of Units on any National Securities Exchange on which Units are then listed or admitted to trading, the value of the Partnership’s assets, the rights and obligations of the Departing General Partner, the value of the Incentive
Distribution Rights and the General Partner Interest and other factors it may deem relevant. 
 (b) If the Combined Interest is
not purchased in the manner set forth in Section 11.3(a), the Departing General Partner (or its transferee) shall become a Limited Partner and its Combined Interest shall be converted into Common Units pursuant to a valuation made by an
investment banking firm or other independent expert selected pursuant to Section 11.3(a), without reduction in such Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor
General Partner shall indemnify the Departing 

  
 86 

Table of Contents

 
General Partner (or its transferee) as to all debts and liabilities of the Partnership arising on or after the date on which the Departing General Partner (or its transferee) becomes a Limited
Partner. For purposes of this Agreement, conversion of the Combined Interest of the Departing General Partner to Common Units will be characterized as if the Departing General Partner (or its transferee) contributed its Combined Interest to the
Partnership in exchange for the newly issued Common Units. 
 (c) If a successor General Partner is elected in accordance with
the terms of Section 11.1 or Section 11.2 (or if the business of the Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner) and the option described
in Section 11.3(a) is not exercised by the party entitled to do so, the successor General Partner shall, at the effective date of its admission to the Partnership, contribute to the Partnership cash in the amount equal to the product of
(x) the quotient obtained by dividing (A) the Percentage Interest of the General Partner Interest of the Departing General Partner by (B) a percentage equal to 100% less the Percentage Interest of the General Partner Interest of the
Departing General Partner and (y) the Net Agreed Value of the Partnership’s assets on such date. In such event, such successor General Partner shall, subject to the following sentence, be entitled to its Percentage Interest of all
Partnership allocations and distributions to which the Departing General Partner was entitled. In addition, the successor General Partner shall cause this Agreement to be amended to reflect that, from and after the date of such successor General
Partner’s admission, the successor General Partner’s interest in all Partnership distributions and allocations shall be its Percentage Interest. 
 Section 11.4 Termination of Subordination Period, Conversion of Subordinated Units and Extinguishment of Cumulative Common Unit Arrearages. Notwithstanding any provision of this Agreement, if
the General Partner is removed as general partner of the Partnership under circumstances where Cause does not exist and Units held by the General Partner and its Affiliates are not voted in favor of such removal, (i) the Subordination Period
will end and all Outstanding Subordinated Units will immediately and automatically convert into Common Units on a one-for-one basis; provided, however, that such converted Subordinated Units shall remain subject to the provisions of
Section 6.7(c), (ii) all Cumulative Common Unit Arrearages on the Common Units will be extinguished and (iii) the General Partner will have the right to convert its General Partner Interest and its Incentive Distribution Rights
into Common Units or to receive cash in exchange therefor in accordance with Section 11.3. 
 Section 11.5
Withdrawal of Limited Partners. No Limited Partner shall have any right to withdraw from the Partnership; provided, however, that when a transferee of a Limited Partner’s Limited Partner Interest becomes a Record Holder of the Limited
Partner Interest so transferred, such transferring Limited Partner shall cease to be a Limited Partner with respect to the Limited Partner Interest so transferred. 
 ARTICLE XII 
 DISSOLUTION AND LIQUIDATION 

Section 12.1 Dissolution. The Partnership shall not be dissolved by the admission of additional Limited Partners or by the
admission of a successor General Partner in accordance with the terms of this Agreement. Upon the removal or withdrawal of the General Partner, if a 

  
 87 

Table of Contents

 
successor General Partner is elected pursuant to Section 11.1, Section 11.2 or Section 12.2, to the fullest extent permitted by law, the Partnership shall not
be dissolved and such successor General Partner shall continue the business of the Partnership. The Partnership shall dissolve, and (subject to Section 12.2) its affairs shall be wound up, upon: 

(a) an Event of Withdrawal of the General Partner as provided in Section 11.1(a) (other than Section 11.1(a)(ii)),
unless a successor is elected and a Withdrawal Opinion of Counsel is received as provided in Section 11.1(b) or 11.2 and such successor is admitted to the Partnership pursuant to Section 10.2; 

(b) an election to dissolve the Partnership by the General Partner that is approved by the holders of a Unit Majority; 

(c) the entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Delaware Act; or 

(d) at any time there are no Limited Partners, unless the Partnership is continued without dissolution in accordance with the Delaware
Act. 
 Section 12.2 Continuation of the Business of the Partnership After Dissolution. Upon (a) dissolution of
the Partnership following an Event of Withdrawal caused by the withdrawal or removal of the General Partner as provided in Section 11.1(a)(i) or (iii) and the failure of the Partners to select a successor to such Departing
General Partner pursuant to Section 11.1 or Section 11.2, then, to the maximum extent permitted by law, within 90 days thereafter, or (b) dissolution of the Partnership upon an event constituting an Event of
Withdrawal as defined in Section 11.1(a)(iv), (v) or (vi), then, to the maximum extent permitted by law, within 180 days thereafter, the holders of a Unit Majority may elect to continue the business of the
Partnership on the same terms and conditions set forth in this Agreement by appointing as a successor General Partner a Person approved by the holders of a Unit Majority. Unless such an election is made within the applicable time period as set forth
above, the Partnership shall conduct only activities necessary to wind up its affairs. If such an election is so made, then: 

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

 (ii) if the successor General Partner is not the former General Partner, then the interest of the former General Partner
shall be treated in the manner provided in Section 11.3; and 
 (iii) the successor General Partner shall be
admitted to the Partnership as General Partner, effective as of the Event of Withdrawal, by agreeing in writing to be bound by this Agreement; 

provided, however, that the right of the holders of a Unit Majority to approve a successor General Partner and to continue the business of the
Partnership shall not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability of any Limited Partner under the Delaware Act
and (y) neither the Partnership nor any Group Member would be treated as an association 

  
 88 

Table of Contents

 
taxable as a corporation or otherwise be taxable as an entity for federal income tax purposes upon the exercise of such right to continue (to the extent not already so treated or taxed).

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

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

(a) The assets may be disposed of by public or private sale or by distribution in kind to one or more Partners on such terms as the
Liquidator and such Partner or Partners may agree. If any property is distributed in kind, the Partner receiving the property shall be deemed for purposes of Section 12.4(c) to have received cash equal to its fair market value; and
contemporaneously therewith, appropriate cash distributions must be made to the other Partners. The Liquidator may defer liquidation or distribution of the Partnership’s assets for a reasonable time if it determines that an immediate sale or
distribution of all or some of the Partnership’s assets would be impractical or would cause undue loss to the Partners. The Liquidator may distribute the Partnership’s assets, in whole or in part, in kind if it determines that a sale would
be impractical or would cause undue loss to the Partners. 
 (b) Liabilities of the Partnership include amounts owed to the
Liquidator as compensation for serving in such capacity (subject to the terms of Section 12.3) and amounts to Partners otherwise than in respect of their distribution rights under Article VI. With respect to any liability that is
contingent, conditional or unmatured or is otherwise not yet due and payable, the Liquidator shall either settle such claim for such amount as it thinks appropriate or establish a 

  
 89 

Table of Contents

 
reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be distributed as additional liquidation proceeds. 

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

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

Section 12.6 Return of Contributions. The General Partner shall not be personally liable for, and shall have no obligation to
contribute or loan any monies or property to the Partnership to enable it to effectuate, the return of the Capital Contributions of the Limited Partners or Unitholders, or any portion thereof, it being expressly understood that any such return shall
be made solely from Partnership assets. 
 Section 12.7 Waiver of Partition. To the maximum extent permitted by law,
each Partner hereby waives any right to partition of the Partnership property. 
 Section 12.8 Capital Account
Restoration. No Limited Partner shall have any obligation to restore any negative balance in its Capital Account upon liquidation of the Partnership. The General Partner shall be obligated to restore any negative balance in its Capital Account
upon liquidation of its interest in the Partnership by the end of the taxable year of the Partnership during which such liquidation occurs, or, if later, within 90 days after the date of such liquidation.

 (d) a change that the General Partner
determines, (i) does not adversely affect the Limited Partners considered as a whole or any particular class of Partnership Interests as compared to other classes of Partnership Interests in any material respect (except as permitted by

agency or judicial authority or contained in any federal or state statute (including the Delaware Act) or (B) facilitate the trading of the Units (including the division of any class or classes of Outstanding Units into different classes to
facilitate uniformity of tax consequences within such classes of Units) or comply with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are or will be listed or admitted to trading, (iii) to
be necessary or appropriate in connection with action taken by the General Partner pursuant to Section 5.9 or (iv) is required to effect the intent expressed in the IPO Registration Statement or the intent of the provisions of this

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

 (k) a merger, conveyance or conversion
pursuant to Section 14.3(d) or Section 14.3(e); or 
 (l) any other amendments substantially similar to
the foregoing. 
 Section 13.2 Amendment Procedures. Amendments to this Agreement may be proposed only by the
General Partner. To the fullest extent permitted by law, the General Partner shall have no duty or obligation to propose or approve any amendment to this Agreement and may decline to do so free of any duty or obligation whatsoever to the
Partnership, any Limited Partner or any other Person bound by this Agreement, and, in declining to propose or approve an amendment to this Agreement, to the fullest extent permitted by law, shall not be required to act in good faith or pursuant to
any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the General Partner in determining whether to propose
or approve any amendment to this Agreement shall be permitted to do so in its sole and absolute discretion. An amendment to this Agreement shall be effective upon its approval by the General Partner and, except as otherwise provided by
Section 13.1 or Section 13.3, the holders of a Unit Majority, unless a greater or different percentage of Outstanding Units is required under this Agreement. Each proposed amendment that requires the approval of the holders
of a specified percentage of Outstanding Units shall be set forth in a writing that contains the text of the proposed amendment. If such an amendment is proposed, the General Partner shall seek the written approval of the requisite percentage of
Outstanding Units or call a meeting of the Unitholders to consider and vote on such proposed amendment. The General Partner shall notify all Record Holders upon final adoption of any amendments. The General Partner shall be deemed to have notified
all Record Holders as required by this Section 13.2 if it has posted or made accessible such amendment through the Partnership’s or the Commission’s website. 

Section 13.3 Amendment Requirements. 
 (a) Notwithstanding the provisions of Section 13.1 and Section 13.2, no provision of this Agreement that establishes a percentage of Outstanding Units required to take any action
shall be amended, altered, changed, repealed or rescinded in any respect that would have the effect of (i) in the case of any provision of this Agreement other than Section 11.2 or Section 13.4, reducing such percentage
or (ii) in the case of Section 11.2 or Section 13.4, increasing such percentages, unless such amendment is approved by the written consent or the affirmative vote of holders of Outstanding Units whose aggregate
Outstanding Units constitute (x) in the case of a reduction as described in subclause (a)(i) hereof, not less than the voting requirement sought to be reduced, (y) in the case of an increase in the percentage in
Section 11.2, not less than 90% of the Outstanding Units, or (z) in the case of an increase in the percentage in Section 13.4, not less than a majority of the Outstanding Units.

Table of Contents

 (b) Notwithstanding the provisions of Section 13.1 and Section 13.2,
no amendment to this Agreement may (i) enlarge the obligations of any Limited Partner without its consent, unless such shall be deemed to have occurred as a result of an amendment approved pursuant to Section 13.3(c) or
(ii) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, the General Partner or any of its Affiliates without its consent, which
consent may be given or withheld at its option. 
 (c) Except as provided in Section 14.3, and without limitation of
the General Partner’s authority to adopt amendments to this Agreement without the approval of any Partners as contemplated in Section 13.1, any amendment that would have a material adverse effect on the rights or preferences of any
class of Partnership Interests in relation to other classes of Partnership Interests must be approved by the holders of not less than a majority of the Outstanding Partnership Interests of the class affected. 

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

(e) Except as provided in Section 13.1, this Section 13.3 shall only be amended with the approval of the holders
of at least 90% of the Outstanding Units. 
 Section 13.4 Special Meetings. All acts of Limited Partners to be taken
pursuant to this Agreement shall be taken in the manner provided in this Article XIII. Special meetings of the Limited Partners may be called by the General Partner or by Limited Partners owning 20% or more of the Outstanding Units of
the class or classes for which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and
indicating the specific purposes for which the special meeting is to be called and the class or classes of Units for which the meeting is proposed. No business may be brought by any Limited Partner before such special meeting except the business
listed in the related request. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules, regulations, listing agreements
or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send or cause to be sent a notice of the meeting to the Limited Partners. A meeting shall be held at a
time and place determined by the General Partner on a date not less than 10 days nor more than 60 days after the time notice of the meeting is given as provided in Section 16.1. Limited Partners shall not be permitted to vote
on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability under the Delaware Act or
the law of any other state in which the Partnership is qualified to do business. If any such vote were to take place, to the fullest extent permitted by law, it shall be deemed null and void to the extent necessary so as not to jeopardize the
Limited 

  
 93 

Table of Contents

 
Partners’ limited liability under the Delaware Act or the law of any other state in which the Partnership is qualified to do business. 

Section 13.5 Notice of a Meeting. Notice of a meeting called pursuant to Section 13.4 shall be given to the
Record Holders of the class or classes of Units for which a meeting is proposed in writing by mail or other means of written communication in accordance with Section 16.1. 

Section 13.6 Record Date. For purposes of determining the Limited Partners who are Record Holders of the class or classes of
Limited Partner Interests entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.11, the General Partner shall set a Record Date, which shall not be less
than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units are listed or admitted to
trading or U.S. federal securities laws, in which case the rule, regulation, guideline or requirement of such National Securities Exchange or U.S. federal securities laws shall govern) or (b) in the event that approvals are sought without a
meeting, the date by which such Limited Partners are requested in writing by the General Partner to give such approvals. 

Section 13.7 Postponement and Adjournment. Prior to the date upon which any meeting of Limited Partners is to be held, the
General Partner may postpone such meeting one or more times for any reason by giving notice to each Limited Partner entitled to vote at the meeting so postponed of the place, date and hour at which such meeting would be held. Such notice shall be
given not fewer than two days before the date of such meeting and otherwise in accordance with this Article XIII. When a meeting is postponed, a new Record Date need not be fixed unless such postponement shall be for more than
45 days. Any meeting of Limited Partners may be adjourned by the General Partner one or more times for any reason, including the failure of a quorum to be present at the meeting with respect to any proposal or the failure of any proposal to
receive sufficient votes for approval. No Limited Partner vote shall be required for any adjournment. A meeting of Limited Partners may be adjourned by the General Partner as to one or more proposals regardless of whether action has been taken on
other matters. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed, if the time and place thereof are announced at the meeting at which the adjournment is
taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 45 days or if
a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII. 
 Section 13.8 Waiver of Notice; Approval of Meeting. The transactions of any meeting of Limited Partners, however called and noticed, and whenever held, shall be as valid as if it had occurred
at a meeting duly held after regular call and notice, if a quorum is present either in person or by proxy. Attendance of a Limited Partner at a meeting shall constitute a waiver of notice of the meeting, except when the Limited Partner attends the
meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a 

  
 94 

Table of Contents

 
waiver of any right to disapprove of any matters submitted for consideration or to object to the failure to submit for consideration any matters required to be included in the notice of the
meeting, but not so included, if such objection is expressly made at the beginning of the meeting. 
 Section 13.9
Quorum and Voting. The presence, in person or by proxy, of holders of a majority of the Outstanding Units of the class or classes for which a meeting has been called (including Outstanding Units deemed owned by the General Partner) shall
constitute a quorum at a meeting of Limited Partners of such class or classes unless any such action by the Limited Partners requires approval by holders of a greater percentage of such Units, in which case the quorum shall be such greater
percentage. At any meeting of the Limited Partners duly called and held in accordance with this Agreement at which a quorum is present, the act of Limited Partners holding Outstanding Units that in the aggregate represent a majority of the
Outstanding Units entitled to vote at such meeting shall be deemed to constitute the act of all Limited Partners, unless a different percentage is required with respect to such action under the provisions of this Agreement, in which case the act of
the Limited Partners holding Outstanding Units that in the aggregate represent at least such different percentage shall be required. The Limited Partners present at a duly called or held meeting at which a quorum is present may continue to transact
business until adjournment, notwithstanding the exit of enough Limited Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by the required percentage of Outstanding Units specified in this Agreement.

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

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

  
 95 

Table of Contents

 
Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Outstanding Units
held by such Limited Partners, the Partnership shall be deemed to have failed to receive a ballot for the Outstanding Units that were not voted. If approval of the taking of any permitted action by the Limited Partners is solicited by any Person
other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) approvals sufficient to take the action proposed are deposited with the Partnership in care of the General Partner,
(b) approvals sufficient to take the action proposed are dated as of a date not more than 90 days prior to the date sufficient approvals are first deposited with the Partnership and (c) an Opinion of Counsel is delivered to the
General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the
business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability, and (ii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the
Partners. 
 Section 13.12 Right to Vote and Related Matters. 

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

(b) With respect to Units that are held for a Person’s account by another Person that is the Record Holder (such as a broker,
dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), such Record Holder shall, in exercising the voting rights in respect of such Units on any matter, and unless the arrangement between such Persons provides
otherwise, vote such Units in favor of, and at the direction of, the Person who is the beneficial owner, and the Partnership shall be entitled to assume such Record Holder is so acting without further inquiry. The provisions of this
Section 13.12(b) (as well as all other provisions of this Agreement) are subject to the provisions of Section 4.3. 
 (c) Notwithstanding anything in this Agreement to the contrary, the Record Holder of an Incentive Distribution Right shall not be entitled to vote such Incentive Distribution Right on any Partnership
matter.

Table of Contents

 (a) Except as provided in Section 14.3(d) and Section 14.3(e), the
General Partner, upon its approval of the Merger Agreement or the Plan of Conversion, as the case may be, shall direct that the Merger Agreement or the Plan of Conversion, as applicable, be submitted to a vote of Limited Partners, whether at a
special meeting or by written consent, in either case in accordance with the requirements of Article XIII. A copy or a summary of the Merger Agreement or the Plan of Conversion, as the case may be, shall be included in or enclosed with
the notice of a special meeting or the written consent and, subject to any applicable requirements of Regulation 14A pursuant to the Exchange Act or successor provision, no other disclosure regarding the proposed merger, consolidation or
conversion shall be required. 
 (b) Except as provided in Section 14.3(d) and Section 14.3(e), the
Merger Agreement or Plan of Conversion, as the case may be, shall be approved upon receiving the affirmative vote or consent of the holders of a Unit Majority unless the Merger Agreement or Plan of Conversion, as the case may be, effects an
amendment to any provision of this Agreement that, if contained in an amendment to this Agreement adopted pursuant to Article XIII, would require for its approval the vote or consent of a greater percentage of the Outstanding Units or of
any class of Limited Partners, in which case such greater percentage vote or consent shall be required for approval of the Merger Agreement or the Plan of Conversion, as the case may be. 

(c) Except as provided in Section 14.3(d) and Section 14.3(e), after such approval by vote or consent of the

forth in the Merger Agreement or Plan of Conversion, as the case may be.

Article XIV or in this Agreement, the General Partner is permitted, without Limited Partner approval, to convert the Partnership or any Group Member into a new limited liability entity, to merge the Partnership or any Group Member into,
or convey all of the Partnership’s assets to, another limited liability entity that shall be newly formed and shall have no assets, liabilities or operations at the time of such conversion, merger or conveyance other than those it receives from
the Partnership or other Group Member if (i) the General Partner has received an Opinion of Counsel that the conversion, merger or conveyance, as the case may be, would not result in the loss of limited liability under the laws of the
jurisdiction governing the other limited liability entity (if that jurisdiction is not Delaware) of any Limited Partner as compared to its limited liability 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 previously treated as such), (ii) the sole purpose of such conversion, merger, or conveyance is to effect a mere change in the legal form of
the Partnership into another limited liability entity and (iii) the General Partner determines that the governing instruments of the new entity provide the Limited Partners and the General Partner with substantially the same rights and
obligations as are herein contained. 
 (e) Additionally, notwithstanding anything else contained in this
Article XIV or in this Agreement, the General Partner is permitted, without Limited Partner approval, to merge or consolidate the Partnership with or into another limited liability entity if (i) the General Partner has received an
Opinion of Counsel that the merger or consolidation, as the case may be, 

  
 99 

Table of Contents

 
would not result in the loss of the limited liability of any Limited Partner under the laws of the jurisdiction governing the other limited liability entity (if that jurisdiction is not Delaware)
as compared to its limited liability 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 previously treated
as such), (ii) the merger or consolidation would not result in an amendment to this Agreement, other than any amendments that could be adopted pursuant to Section 13.1, (iii) the Partnership is the Surviving Business Entity in
such merger or consolidation, (iv) each Unit outstanding immediately prior to the effective date of the merger or consolidation is to be an identical Unit of the Partnership after the effective date of the merger or consolidation, and

date of such merger or consolidation. 
 (f) Pursuant to Section 17-211(g) of the Delaware Act, an agreement of merger or
consolidation approved in accordance with this Article XIV may (i) effect any amendment to this Agreement or (ii) effect the adoption of a new partnership agreement for the Partnership if it is the Surviving Business Entity.
Any such amendment or adoption made pursuant to this Section 14.3 shall be effective at the effective time or date of the merger or consolidation. 
 Section 14.4 Certificate of Merger or Certificate of Conversion. Upon the required approval by the General Partner and the Unitholders of a Merger Agreement or the Plan of Conversion, as the
case may be, a certificate of merger or certificate of conversion or other filing, as applicable, shall be executed and filed with the Secretary of State of the State of Delaware or the appropriate filing office of any other jurisdiction, as
applicable, in conformity with the requirements of the Delaware Act or other applicable law. 
 Section 14.5 Effect of

(i) all of the rights, privileges and powers of each of the business entities that has merged or consolidated, and all property, real,
personal and mixed, and all debts due to any of those business entities and all other things and causes of action belonging to each of those business entities, shall be vested in the Surviving Business Entity and after the merger or consolidation
shall be the property of the Surviving Business Entity to the extent they were of each constituent business entity; 
 (ii) the
title to any real property vested by deed or otherwise in any of those constituent business entities shall not revert and is not in any way impaired because of the merger or consolidation;

 100

Table of Contents

 (iv) all debts, liabilities and duties of those constituent business entities shall attach
to the Surviving Business Entity and may be enforced against it to the same extent as if the debts, liabilities and duties had been incurred or contracted by it. 
 (b) At the effective time of the conversion: 
 (i) the Partnership shall continue
to exist, without interruption, but in the organizational form of the converted entity rather than in its prior organizational form; 
 (ii) all rights, title, and interests to all real estate and other property owned by the Partnership shall continue to be owned by the converted entity in its new organizational form without reversion or
impairment, without further act or deed, and without any transfer or assignment having occurred, but subject to any existing liens or other encumbrances thereon; 
 (iii) all liabilities and obligations of the Partnership shall continue to be liabilities and obligations of the converted entity in its new organizational form without impairment or diminution by reason
of the conversion; 
 (iv) all rights of creditors or other parties with respect to or against the prior interest holders or
other owners of the Partnership in their capacities as such in existence as of the effective time of the conversion will continue in existence as to those liabilities and obligations and may be pursued by such creditors and obligees as if the
conversion did not occur; 
 (v) a proceeding pending by or against the Partnership or by or against any of Partners in their
capacities as such may be continued by or against the converted entity in its new organizational form and by or against the prior Partners without any need for substitution of parties; and

in the converted entity as provided in the plan of conversion shall be so converted, and Partners shall be entitled only to the rights provided in the Plan of Conversion.

 RIGHT TO ACQUIRE LIMITED PARTNER INTERESTS 

Section 15.1 Right to Acquire Limited Partner Interests. 

(a) Notwithstanding any other provision of this Agreement, if at any time the General Partner and its Affiliates hold more than 85% of
the total Limited Partner Interests of any class then Outstanding, the General Partner shall then have the right, which right it may assign and transfer in whole or in part to the Partnership or any Affiliate of the General Partner, exercisable at
its option, to purchase all, but not less than all, of such Limited Partner Interests of such class then Outstanding held by Persons other than the General Partner and its Affiliates, at the greater of (x) the Current Market Price as of the
date three Business Days prior to the date that the notice described in Section 15.1(b) is mailed and (y) the highest price paid by the General Partner or any of its Affiliates for any such Limited Partner Interest of such class

  
 101

Table of Contents

 
purchased during the 90-day period preceding the date that the notice described in Section 15.1(b) is mailed. 
 (b) If the General Partner, any Affiliate of the General Partner or the Partnership elects to exercise the right to purchase Limited Partner Interests granted pursuant to Section 15.1(a), the
General Partner shall deliver to the applicable Transfer Agent or exchange agent notice of such election to purchase (the “Notice of Election to Purchase”) and shall cause the Transfer Agent or exchange agent to mail a copy
of such Notice of Election to Purchase to the Record Holders of Limited Partner Interests of such class (as of a Record Date selected by the General Partner), together with such information as may be required by law, rule or regulation, at least 10,
but not more than 60, days prior to the Purchase Date. Such Notice of Election to Purchase shall also be filed and distributed as may be required by the Commission or any National Securities Exchange on which such Limited Partner Interests are
listed. The Notice of Election to Purchase shall specify the Purchase Date and the price (determined in accordance with Section 15.1(a)) at which Limited Partner Interests will be purchased and state that the General Partner, its
Affiliate or the Partnership, as the case may be, elects to purchase such Limited Partner Interests, upon surrender of Certificates representing such Limited Partner Interests, in the case of Limited Partner Interests evidenced by Certificates, or
instructions agreeing to such redemption in exchange for payment, at such office or offices of the Transfer Agent or exchange agent as the Transfer Agent or exchange agent may specify, or as may be required by any National Securities Exchange on
which such Limited Partner Interests are listed. Any such Notice of Election to Purchase mailed to a Record Holder of Limited Partner Interests at his address as reflected in the Partnership Register shall be conclusively presumed to have been given
regardless of whether the owner receives such notice. On or prior to the Purchase Date, the General Partner, its Affiliate or the Partnership, as the case may be, shall deposit with the Transfer Agent or exchange agent cash in an amount sufficient
to pay the aggregate purchase price of all of such Limited Partner Interests to be purchased in accordance with this Section 15.1. If the Notice of Election to Purchase shall have been duly given as aforesaid at least 10 days prior
to the Purchase Date, and if on or prior to the Purchase Date the deposit described in the preceding sentence has been made for the benefit of the holders of Limited Partner Interests subject to purchase as provided herein, then from and after the
Purchase Date, notwithstanding that any Certificate or redemption instructions shall not have been surrendered for purchase or provided, respectively, all rights of the holders of such Limited Partner Interests (including any rights pursuant to
Article IV, Article V, Article VI, and Article XII) shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 15.1(a)) for Limited Partner
Interests therefor, without interest, upon surrender to the Transfer Agent or exchange agent of the Certificates representing such Limited Partner Interests, in the case of Limited Partner Interests evidenced by Certificates, or instructions
agreeing to such redemption, and such Limited Partner Interests shall thereupon be deemed to be transferred to the General Partner, its Affiliate or the Partnership, as the case may be, on the Partnership Register, and the General Partner or any
Affiliate of the General Partner, or the Partnership, as the case may be, shall be deemed to be the Record Holder of all such Limited Partner Interests from and after the Purchase Date and shall have all rights as the Record Holder of such Limited
Partner Interests (including all rights as owner of such Limited Partner Interests pursuant to Article IV, Article V, Article VI and Article XII).

 (c) In the case of Limited Partner Interests evidenced by Certificates, at any time from and
after the Purchase Date, a holder of an Outstanding Limited Partner Interest subject to purchase as provided in this Section 15.1 may surrender his Certificate evidencing such Limited Partner Interest to the Transfer Agent or exchange
agent in exchange for payment of the amount described in Section 15.1(a) therefor, without interest thereon, in accordance with procedures set forth by the General Partner.

payment or report addressed to a Record Holder at the address of such Record Holder appearing in the Partnership Register is returned by the United States Postal Service marked to indicate that the United States Postal Service is unable to deliver
it, such notice, payment or report and any subsequent notices, payments and reports shall be deemed to have been duly given or made without further mailing (until such time as such Record Holder or another Person notifies the Transfer Agent or the
Partnership of a change in his address) if they are available for the Partner at the principal office of the Partnership for a period of one year from the date of the giving or making of such notice, payment or report to the other Partners. Any

 In accordance with Section 4.1 of the First Amended and Restated Agreement of Limited Partnership of

 THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF MPLX LP THAT THIS SECURITY MAY NOT BE TRANSFERRED IF
