 ARTICLE III 
 REPRESENTATIONS AND WARRANTIES OF HPIP 
 HPIP hereby represents and
warrants to AMID as follows: 
 3.1 Organization; Qualification. Each of HPIP and the High Point Entities is an
entity duly formed, validly existing and in good standing under the laws of the State of Delaware and has all requisite organizational power and authority to own, lease and operate its properties and to carry on its business as it is now being
conducted. Each High Point Entity is duly qualified, registered or licensed to do business as a foreign entity and is in good standing in each jurisdiction in which the property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification necessary, except where the failure to be so duly qualified, registered or licensed and in good standing would not reasonably be expected to have a High Point Material Adverse Effect or to prevent or materially delay
the consummation of the transactions contemplated by the Transaction Documents to which HPIP is a party or to materially impair HPIP’s ability to perform its obligations under the Transaction Documents to which it is a party. HPIP has made
available to AMID true and complete copies of the Organizational Documents of HPIP and the High Point Entities, as in effect on the Closing Date. 
 3.2 Authority; Enforceability. 
 (a) HPIP has the requisite limited
liability company power and authority to execute and deliver the Transaction Documents to which it is a party, and to consummate the transactions contemplated thereby. The execution and delivery by HPIP of the Transaction Documents to which HPIP is
a party, and the consummation by HPIP of the transactions contemplated thereby, have been duly and validly authorized by HPIP, and no other proceedings on the part of HPIP are necessary to authorize the Transaction Documents to which it is a party
or to consummate the transactions contemplated by the Transaction Documents to which it is a party. 
 (b) The Transaction
Documents to which HPIP is a party have been duly executed and delivered by HPIP, and, assuming the due authorization, execution and delivery by the other parties thereto, each Transaction Document to which HPIP is a party constitutes the valid and
binding agreement of HPIP, enforceable against HPIP in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Laws relating to or
affecting creditors’ rights generally and subject, as to enforceability, to legal principles of general applicability governing the availability of equitable remedies, including principles of commercial reasonableness, good faith and fair
dealing (regardless of whether such enforceability is considered in a proceeding in equity or at law) (collectively, “Creditors’ Rights”). 
 3.3 Non-Contravention. 
 (a) Except as set forth on Schedule
3.3(a) of the HPIP Disclosure Schedules, the execution, delivery and performance by HPIP of the Transaction Documents to which HPIP is a party, and the consummation by HPIP of the transactions contemplated thereby, do not and will not:
(i) result in any breach of any provision of the Organizational Documents of HPIP; (ii)

  
 5 

 
assuming compliance with the matters referred to in Section 3.4, violate any Law to which HPIP is subject or by which any of HPIP’s properties or assets is bound, except, in the
case of clause (ii) for such defaults or rights of termination, cancellation, amendment or acceleration or violations as would not reasonably be expected to prevent or materially delay the consummation of the transactions contemplated by the
Transaction Documents to which HPIP is a party or to materially impair HPIP’s ability to perform its obligations under the Transaction Documents to which it is a party. 
 (b) Except as set forth on Schedule 3.3(b) of the HPIP Disclosure Schedules, the execution, delivery and performance of the Transaction Documents to which HPIP is a party by HPIP and the
consummation by HPIP of the transactions contemplated thereby does not and will not: (i) result in any breach of any provision of the Organizational Documents of the High Point Entities; (ii) constitute a default (or an event that with the
giving of notice or the passage of time or both would give rise to a default) or cause any obligation under, or give rise to any right of termination, cancellation, amendment, preferential purchase right or acceleration (with or without the giving
of notice, or the passage of time or both) under any of the terms, conditions or provisions of any Contract to which any High Point Entity is a party or by which any property or assets of any High Point Entity is bound or affected;
(iii) assuming compliance with the matters referred to in Section 3.4, violate any Law to which any High Point Entity is subject or by which any High Point Entity’s properties or assets is bound; (iv) constitute (with or
without the giving of notice or the passage of time or both) an event that would result in the creation of any Lien (other than Permitted Liens) on any asset of any High Point Entity; or (v) cause any High Point Entity to become subject to, or
to become liable for the payment of, any Tax, except, in the cases of clauses (ii), (iii) and (iv), for such defaults or rights of termination, cancellation, amendment or acceleration, violations or Liens, as would not reasonably be expected to
have a High Point Material Adverse Effect. 
 3.4 Governmental Approvals. Except as set forth on Schedule
3.4 of the HPIP Disclosure Schedules, no declaration, filing or registration with, or notice to, or authorization, consent or approval of, any Governmental Authority by HPIP or either of the High Point Entities is necessary for the consummation
by HPIP of the transactions contemplated by the Transaction Documents to which it is a party, other than such declarations, filings, registrations, notices, authorizations, consents or approvals that have been obtained or made or that would in the
ordinary course be made or obtained after the Closing, or which, if not obtained or made, would not reasonably be expected to prevent or materially delay the consummation of the transactions contemplated by the Transaction Documents to which HPIP is
a party or to materially impair HPIP’s ability to perform its obligations under the Transaction Documents to which it is a party.

as applicable, in each of the High Point Subsidiaries; such equity interests have been duly authorized and validly issued in accordance with the Organizational Documents of each High Point Subsidiary and are fully paid (to the extent required under

Contract or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to the Convertible Preferred Units. HPIP acknowledges and understands that (i) the acquisition of the
Convertible Preferred Units has not been registered under the Securities Act in reliance on an exemption therefrom and (ii) the Convertible Preferred Units will, upon such acquisition, be characterized as “restricted securities” under
state and federal securities laws. HPIP agrees that the Convertible Preferred Units may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of except pursuant to an effective registration statement under the
Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with other applicable state and federal securities laws. HPIP acknowledges and agrees that the Convertible Preferred
Securities will, when issued, include the restrictive legend specified in Section 5.12(b)(vii) (B) of the Third Amended and Restated Partnership Agreement. 
 (b) HPIP has undertaken such investigation as it has deemed necessary to enable it to make an informed and intelligent decision with respect to the execution, delivery and performance of this Agreement
and the acquisition of the Convertible Preferred Units. HPIP has had an opportunity to ask questions and receive answers from AMID regarding the terms and conditions of the offering of the Convertible Preferred Units and the business, properties,
prospects and financial condition of AMID. The foregoing, however, does not modify the representations and warranties of AMID in Article IV and such representations and warranties constitute the sole and exclusive representations and
warranties of AMID to HPIP in connection with the transactions contemplated by this Agreement.

any business practice of any of the High Point Entities, any acquisition of property by any of the High Point Entities, the purchase of goods or services from any party, the hiring of any individual or groups of individuals or the conduct of
business by any of the High Point Entities as currently conducted. 
 3.25 Adequacy of Assets. The tangible assets
to be owned by the High Point Entities immediately after the Closing will be adequate to permit such High Point Entities to conduct their respective business in substantially the same manner as conducted prior to Closing.

4.4 Governmental Approvals. Except as set forth on Schedule 4.4 of the AMID Disclosure Schedules, no declaration,

its investment in the High Point Interests and is capable of bearing the economic risk of such investment. AMID is an “accredited investor” as that term is defined in Rule 501 of Regulation D (without regard to Rule 501(a)(4)) promulgated
under the Securities Act. AMID is acquiring the High Point Interests for investment for its own account and not with a view toward or for sale in connection with any distribution thereof, or with any present intention of distributing or selling the
High Point Interests. AMID does not have any Contract or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to the High Point Interests. AMID acknowledges and understands that
(i) the acquisition of the High Point Interests has not been registered under the Securities Act in reliance on an exemption therefrom and (ii) the High Point Interests will, upon such acquisition, be characterized as “restricted
securities” under state and federal securities laws. AMID agrees that the High Point Interests may not be sold, transferred, offered for sale, pledged, hypothecated or otherwise disposed of except (A) in accordance with the requirements of
each High Point Entity LLC Agreement, (B) pursuant to an effective registration statement under the Securities Act or pursuant to an available exemption from the registration requirements of the Securities Act, and in compliance with other
applicable state and federal securities laws or (C) to the extent pledged or hypothecated pursuant to the terms of the AMID Credit Facility.

 34 

 
conditions of the offering of the High Point Interests and the business, properties, prospects, and financial condition of the High Point Entities (to the extent HPIP possessed such information).

transactions contemplated by this Agreement.

property by any of the AMID Entities, the purchase of goods or services from any party, the hiring of any individual or groups of individuals or the conduct of business by any of the AMID Entities as currently conducted. 

4.26 Adequacy of Assets. The tangible assets to be owned by the AMID Entities immediately after the Closing will be
adequate to permit such AMID Entities to conduct their respective business in substantially the same manner as conducted prior to Closing, except that no representation or warranty is made herein with respect to the adequacy of the assets or
properties of the High Point Entities.

transactions contemplated hereby. 
 (h) Tax Treatment. Any payments made to any Party pursuant to Article
VI shall constitute an adjustment of the amount of the AMID Consideration (first as an adjustment of the amount of the Cash Contribution to the extent thereof) for Tax purposes and shall be treated as such by the Parties on their Tax Returns to

Party allegedly required to provide indemnification protection under this Article VI specifying, in reasonable detail, the nature and basis for such Claim (e.g., the underlying representation, warranty, covenant or agreement alleged to
have been breached) and the amount thereof (to the extent the nature and amount of such Claim is known or reasonably ascertainable at the time). Notwithstanding the foregoing, an Indemnitee’s failure to send or delay in sending a third party
Claim Notice will not relieve the Indemnifying Party from liability hereunder with respect to such Claim except to the extent the Indemnifying Party is prejudiced by such failure or delay and except as is otherwise provided herein, including in
Section 6.3(e).

 NOW, THEREFORE, the General Partner does hereby amend and restate the Second A/R
Partnership Agreement to provide in its entirety 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, merger,
stock acquisition 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 the long-term 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. 

“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. 

(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

  
 2 

 
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). 

“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. 
 “Additional Limited Partner” means a Person admitted to the Partnership as a Limited Partner pursuant to Section 10.1(b) and who is shown as such on the books and
records of the Partnership. 
 “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 Section 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 a 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) any net increase in Working Capital Borrowings with respect to that period and (ii) any net decrease in cash reserves for Operating Expenditures
with respect to such period not relating to an Operating Expenditure made with respect to such period, and plus (c) (i) any net decrease in Working Capital Borrowings with 

  
 3 

 
respect to that period, (ii) 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) any net increase in cash reserves for Operating Expenditures with respect to such period required by any debt
instrument for the repayment of principal, interest or premium. Adjusted Operating Surplus does not include that portion of Operating Surplus included in clause (a)(i) of the definition of Operating Surplus. 

“Adjusted Property” means any property the Carrying Value of which has been adjusted pursuant to
Section 5.5(d). 
 “Affiliate” means, with respect to any Person, any other Person that
directly or indirectly through one or more 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 and policies of a Person, whether through ownership of voting securities, by contract or otherwise. 
 “Aggregate Quantity of IDR Reset Common Units” has the meaning assigned to such term in Section 5.11(a). 

“Aggregate Remaining Net Positive Adjustments” means, as of the end of any taxable period, the sum of the
Remaining Net Positive Adjustments of all the Partners.

of such property or other consideration 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. 
 “Agreement” means this Second Amended and Restated
Agreement of Limited Partnership of American Midstream Partners, LP, as it may be amended, supplemented or restated from time to time. 
 “AIM Midstream” means AIM Midstream Holdings, LLC, a Delaware limited liability company. 
 “American Midstream GP” means American Midstream GP, LLC, a Delaware limited liability company. 
 “Associate” means, when used to indicate a relationship with any Person, (a) any corporation or organization of which such Person is a director, officer, 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 such Person serves as
trustee or in a similar fiduciary capacity; and (c) any relative or spouse of such Person, or any relative of such spouse, who has the same principal residence as such Person. 

  
 4 

 “Available Cash” means, with respect to any Quarter ending prior to
the Liquidation Date: 
 (a) the sum of: 
 (i) all cash and cash equivalents of the Partnership Group (or the Partnership’s proportionate share of cash and cash equivalents in the case of Subsidiaries that are not wholly owned) on hand at the
end of such Quarter; and 
 (ii) if the General Partner so determines, all or any portion of additional cash and cash
equivalents of the Partnership Group (or the Partnership’s proportionate share of cash and cash equivalents in the case of Subsidiaries that are not wholly owned) on hand on the date of determination of Available Cash with respect to such
Quarter resulting from Working Capital Borrowings made subsequent to the end of such Quarter; 
 (b) less the amount of any cash
reserves (or the Partnership’s proportionate share of cash reserves in the case of Subsidiaries that are not wholly owned) established by the General Partner to: 
 (i) provide for the proper conduct of the business of the Partnership Group (including reserves for future capital expenditures, for anticipated future credit needs of the Partnership Group and for
refunds of collected rates reasonably likely to be refunded as a result of a settlement or hearing relating to FERC rate proceedings or rate proceedings under applicable state law, if any) subsequent to such Quarter; 

(ii) comply with applicable law or any loan agreement, security agreement, mortgage, debt instrument or other agreement or obligation to
which any Group Member is a party or by which it is bound or its assets are subject; or 
 (iii) provide funds for distributions
under Section 6.4 or Section 6.5 in respect of any one or more of the next four Quarters; 
 provided,
however, that the General Partner may not establish cash reserves pursuant to clause (iii) above if the effect of establishing such reserves would be that the Partnership is unable to distribute the Minimum Quarterly Distribution on all
Common Units, plus any Cumulative Common Unit Arrearage on all Common Units, with respect to such Quarter; and, 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 deemed to have been made, established, increased or reduced, for purposes of determining Available Cash, within such Quarter if the
General Partner so determines. 
 Notwithstanding the foregoing, “Available Cash” with respect to the Quarter
in which the Liquidation Date occurs and any subsequent Quarter shall equal zero.

 “Book-Up Event” means an event that triggers a positive adjustment to the Capital Accounts of the Partners pursuant to Section 5.5(d).

“Capital Contribution” means (i) any cash, cash equivalents or the Net Agreed Value of Contributed Property
that a Partner contributes to the Partnership or that is contributed or deemed contributed to the Partnership on behalf of a Partner (including, in the case of an underwritten offering of Units, the amount of any underwriting discounts or

“Capital Improvement” means any (a) addition or improvement to the capital assets owned by any Group Member,

processing plants, transmission lines and related or similar midstream assets) or (c) capital contribution by a Group Member to a Person that is not a Subsidiary in which a Group Member has, or after such capital contribution will have, an

of new or replacement of existing, capital assets (including gathering systems, compressors, processing plants, transmission lines and related or similar midstream assets) by such Person, in each case if

  
 6

case of clauses (a) and (b), or such Person, in the case of clause (c), from the operating capacity or operating income of the Partnership Group or such Person, as the case may be, existing immediately prior to such addition, improvement,

connection therewith, to exercise all of the rights and powers conferred upon the 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

transfer of record title to the Partnership and, prior to any such transfer, will provide for the use of such

 ARTICLE IV

 PARTNERSHIP INTERESTS; REDEMPTION OF
PARTNERSHIP INTERESTS

Notwithstanding anything otherwise to the contrary herein, unless the General Partner shall determine otherwise in respect of some or all
of any or all classes of Partnership Interests, Partnership Interests shall not be evidenced by certificates; provided, however, with respect to the issuance of any Series A Preferred Units, the Partnership shall issue such
Certificates in accordance with Section 5.12(b)(vii). Certificates that may be issued shall be executed on behalf of the Partnership by the Chairman of the Board, President or any Executive Vice President or Vice President and the Chief
Financial Officer or the Secretary or any Assistant Secretary of the General Partner. No Certificate for a class of Partnership Interests shall be valid for any purpose until it has been countersigned by the Transfer Agent for such class of
Partnership Interests; provided, however, that if the General Partner elects to cause the Partnership to issue Partnership Interests of such class in global form, the Certificate shall be valid upon receipt of a certificate from the
Transfer Agent certifying that the Partnership Interests have been duly registered in accordance with the directions of the Partnership. Subject to the requirements of Section 6.7(c), if Common Units are evidenced by Certificates, on or
after the date on which Subordinated Units are converted into Common Units pursuant to the terms of Section 5.7, the Record Holders of such Subordinated Units (i) if the Subordinated Units are evidenced by Certificates, may exchange
such Certificates for Certificates evidencing Common Units or (ii) if the Subordinated Units are not evidenced by Certificates, shall be issued Certificates evidencing Common Units. 

  
 35 

 Section 4.2 Mutilated, Destroyed, Lost or Stolen Certificates. 

(a) If any mutilated Certificate is surrendered to the Transfer Agent (for Common Units) or the General Partner (for Partnership
Interests other than Common Units), the appropriate officers of the General Partner on behalf of the Partnership shall execute, and the Transfer Agent (for Common Units) or the General Partner (for Partnership Interests other than Common Units)
shall countersign and deliver in exchange therefor, a new Certificate evidencing the same number and type of Partnership Interests as the Certificate so surrendered. 
 (b) The appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and the Transfer Agent (for Common Units) shall countersign, a new Certificate in place of any
Certificate previously issued, or issue uncertificated Common Units, if the Record Holder of the Certificate: 
 (i) makes proof
by affidavit, in form and substance satisfactory to the General Partner, that a previously issued Certificate has been lost, destroyed or stolen; 
 (ii) requests the issuance of a new Certificate or the issuance of uncertificated Units before the General Partner has notice that the Certificate has been acquired by a purchaser for value in good faith
and without notice of an adverse claim; 
 (iii) if requested by the General Partner, delivers to the General Partner a bond, in
form and substance satisfactory to the General Partner, with surety or sureties and with fixed or open penalty as the General Partner may direct to indemnify the Partnership, the Partners, the General Partner and the Transfer Agent against any claim
that may be made on account of the alleged loss, destruction or theft of the Certificate; and 
 (iv) satisfies any other
reasonable requirements imposed by the General Partner.

Transfer Agent receives such notification, 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 or uncertificated Units.

 (c) As a condition to the issuance of any new Certificate or uncertificated Units under this Section 4.2, the

therewith. 

  
 36 

 Section 4.3 Record Holders. 

The Partnership shall be entitled to recognize the Record Holder as the Partner with respect to any Partnership Interest and,
accordingly, shall not be bound to recognize any equitable or other claim to, or interest in, such Partnership Interest on the part of any other Person, regardless of whether the Partnership shall have actual or other notice thereof, except as
otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading. Without limiting the foregoing, when a Person (such as
a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing) is acting as nominee, agent or in some other representative capacity for another Person in acquiring and/or holding Partnership Interests, as between
the Partnership on the one hand, and such other Persons on the other, such representative Person shall be (a) the Record Holder of such Partnership Interest and (b) bound by this Agreement and shall have the rights and obligations of a
Partner, as the case may be, hereunder as, and to the extent, provided herein. 
 Section 4.4 Transfer Generally.

 (a) The term “transfer,” when used in this Agreement with respect to a Partnership Interest, shall
mean a transaction (i) by which the General Partner assigns its General Partner Interest to another Person, and includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or
otherwise or (ii) by which the holder of a Limited Partner Interest assigns such Limited Partner Interest to another Person who is or becomes a Limited Partner, and includes a sale, assignment, gift, exchange or any other disposition by law or
otherwise, excluding a pledge, encumbrance, hypothecation or mortgage but including any transfer upon foreclosure of any pledge, encumbrance, hypothecation or mortgage. 
 (b) No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Article IV. Any transfer or purported transfer of a
Partnership Interest not made in accordance with this Article IV shall be, to the fullest extent permitted by law, null and void. 
 (c) Nothing contained in this Agreement shall be construed to prevent a disposition by any stockholder, member, partner or other owner of any Partner of any or all of the shares of stock, membership or
limited liability company interests, partnership interests or other ownership interests in such Partner, and the term “transfer” shall not mean any such disposition. 
 Section 4.5 Registration and Transfer of Limited Partner Interests. 

(a) The General Partner shall keep or cause to be kept on behalf of the Partnership a register in which, subject to such reasonable
regulations as it may prescribe and subject to the provisions of Section 4.5(b), the Partnership will provide for the registration and transfer of Limited Partner Interests. 

(b) The Partnership shall not recognize any transfer of Limited Partner Interests evidenced by Certificates until the Certificates
evidencing such Limited Partner Interests are surrendered for registration of transfer. No charge shall be imposed by the General Partner for such transfer; provided, that as a condition to the issuance of any new Certificate under this

  
 37 

 
Section 4.5, the General Partner may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed with respect thereto. Upon surrender of
a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions hereof, the appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and
in the case of Certificates evidencing Limited Partner Interests, the Transfer Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or
more new Certificates evidencing the same aggregate number and type of Limited Partner Interests as was evidenced by the Certificate so surrendered. 
 (c) By acceptance of the transfer of any Limited Partner Interests in accordance with this Section 4.5 and except as provided in Section 4.9, each transferee of a Limited Partner
Interest (including any nominee holder or an agent or representative acquiring such Limited Partner Interests for the account of another Person) (i) shall be admitted to the Partnership as a Limited Partner with respect to the Limited Partner
Interests so transferred to such Person when any such transfer or admission is reflected in the books and records of the Partnership and such Limited Partner becomes the Record Holder of the Limited Partner Interests so transferred, (ii) shall
become bound, and shall be deemed to have agreed to be bound, by the terms of this Agreement, (iii) represents that the transferee has the capacity, power and authority to enter into this Agreement and (iv) makes the consents,
acknowledgements and 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. 
 (d) Subject to (i) the foregoing provisions of this Section 4.5,
(ii) Section 4.3, (iii) Section 4.8, (iv) with respect to any class or series of Limited Partner Interests, the provisions of any statement of designations or an amendment to this Agreement establishing such class
or series, (v) any contractual provisions binding on any Limited Partner and (vi) provisions of applicable law including the Securities Act, Limited Partner Interests shall be freely transferable. 

(e) The General Partner and its Affiliates shall have the right at any time to transfer their Subordinated Units, Common Units and
Incentive Distribution Rights to one or more Persons. 
 Section 4.6 Transfer of the General Partner’s General
Partner Interest. 
 (a) Subject to Section 4.6(c) below, prior to June 30, 2020, the General Partner shall not
transfer all or any part of its General Partner Interest (represented by Notional General Partner Units) to a Person unless such transfer (i) has been approved by the prior written consent or vote of the holders of at least a majority of the
Outstanding Common Units (excluding Common Units held by the General Partner and its Affiliates) or (ii) is of all, but not less than all, of its General Partner Interest to (A) an Affiliate of the General Partner (other than an
individual) or (B) another Person (other than an individual) in connection with the merger or consolidation of the General Partner with or into such other Person or the transfer by the General Partner of all or substantially all of its assets
to such other Person. 

  
 38 

 (b) Subject to Section 4.6(c) below, on or after June 30, 2020, the General
Partner may transfer all or any of its General Partner Interest without Unitholder approval. 
 (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 limited liability company membership interest held by the General Partner as the general partner or managing member, if any, of each other Group Member. In the case of a
transfer pursuant to and in compliance with this Section 4.6, the transferee or successor (as the case may be) shall, subject to compliance with the terms of Section 10.2, be admitted to the Partnership as the General Partner
effective immediately prior to the transfer of the General Partner Interest, and the business of the Partnership shall continue without dissolution. 
 Section 4.7 Transfer of Incentive Distribution Rights. 
 The General
Partner or any other holder of Incentive Distribution Rights may transfer any or all of its Incentive Distribution Rights without Unitholder approval. 
 Section 4.8 Restrictions on Transfers. 
 (a) Notwithstanding the other
provisions of this Article IV, no transfer of any Partnership Interests shall be made if such transfer would (i) 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). 

(b) The General Partner may impose restrictions on the transfer of Partnership Interests if it determines, with the advice of counsel,
that such restrictions are necessary or advisable to (i) avoid a significant risk of the Partnership becoming taxable as a corporation or otherwise becoming taxable as an entity for U.S. federal income tax purposes 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. 
 (c) The transfer
of a Common Unit that has been issued upon conversion of a Subordinated Unit shall be subject to the restrictions imposed by Section 6.7(c). 

  
 39 

 (d) The transfer of Common Units that have been issued upon conversion of Incentive
Distribution Rights shall be subject to the restrictions imposed by Section 6.8(b). 
 (e) Nothing contained in this
Agreement, other than Section 4.8(a), shall preclude the settlement of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership Interests are
listed or admitted to trading. 
 (f) Any transfer of a Conversion Unit shall be subject to the restrictions imposed by
Section 6.10. 
 Section 4.9 Eligibility Certifications; Ineligible Holders. 

(a) If at any time the General Partner determines, with the advice of counsel, that 

(i) the U.S. federal income tax status (or lack of proof of the U.S. federal income tax status) of one or more Limited Partners has or is
reasonably likely to have a material adverse effect on the rates that can be charged to customers by any Group Member on assets that are subject to regulation by the FERC or analogous regulatory body (a “Rate Eligibility
Trigger”); or 
 (ii) any Group Member is subject to any federal, state or local law or regulation that would
create a substantial risk of cancellation or forfeiture of any property in which the Group Member has an interest based on the nationality, citizenship or other related status of a Partner (a “Citizenship Eligibility
Trigger”); 
 then, the General Partner may adopt such amendments to this Agreement as it determines to be necessary or advisable
to (x) in the case of a Rate Eligibility Trigger, obtain such proof of the U.S. federal income tax status of the Limited Partners and, to the extent relevant, their beneficial owners, as the General Partner determines to be necessary to
establish those Limited Partners whose U.S. federal income tax status does not or would not have a material adverse effect on the rates that can be charged to customers by any Group Member or (y) in the case of a Citizenship Eligibility
Trigger, obtain such proof of the nationality, citizenship or other related status of the Partner (or, if the Partner is a nominee holding for the account of another Person, the nationality, citizenship or other related status of such Person) as the
General Partner determines to be necessary to establish those Partners whose status as Partners does not or would not subject any Group Member to a significant risk of cancellation or forfeiture of any of its properties or interests therein.

 (b) Such amendments may include provisions requiring all Partners to certify as to their (and their beneficial owners’)
status as Eligible Holders upon demand and on a regular basis, as determined by the General Partner, and may require transferees of Units to so certify prior to being admitted to the Partnership as a Partner (any such required certificate, an
“Eligibility Certificate”). 
 (c) Such amendments may provide that any Partner who fails to furnish to
the General Partner within a reasonable period requested proof of its (and its beneficial owners’) status as an Eligible Holder or if upon receipt of such Eligibility Certificate or other requested

  
 40 

 
information the General Partner determines that a Partner is not an Eligible Holder (such a Partner an “Ineligible Holder”) the Partnership Interests owned by such Limited
Partner shall be subject to redemption in accordance with the provisions of Section 4.10. In addition, the General Partner shall be substituted for all Limited Partners that are Ineligible Holders as the Limited Partner in respect of the
Ineligible Holders’ Partnership Interests. 
 (d) The General Partner shall, in exercising voting rights in respect of
Partnership Interests held by it on behalf of Ineligible Holders, distribute the votes in the same ratios as the votes of Partners (including the General Partner and its Affiliates) in respect of Partnership Interests other than those of Ineligible
Holders are cast, either for, against or abstaining as to the matter. 
 (e) 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 his Partnership Interest (representing his right to receive his
share of such distribution in kind). 
 (f) At any time after an Ineligible Holder can and does certify that he has become an
Eligible Holder, an Ineligible Holder may, upon application to the General Partner, request that with respect to any Partnership Interests of such Ineligible Holder not redeemed pursuant to Section 4.10, such Ineligible Holder be
admitted as a Limited Partner, and upon approval of the General Partner, such Ineligible Holder shall be admitted as a Limited Partner and 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 Ineligible Holder’s Partnership Interests. 
 Section 4.10 Redemption of
Partnership Interests of Ineligible Holders. 
 (a) If at any time a Partner fails to furnish an Eligibility Certificate or
other information requested within the period of time specified in amendments adopted pursuant to 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 Partner is not an Eligible Holder, the Partnership may, unless the Partner establishes to the satisfaction of the General Partner that such Partner is an Eligible Holder or has transferred his Partnership Interests to a Person who is
an Eligible Holder and who furnishes an Eligibility Certificate to the General Partner prior to the date fixed for redemption as provided below, redeem the Partnership Interest of such 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
Partner, at his 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 Certificates evidencing the Redeemable Interests) and that on and after the date fixed for redemption no further allocations or distributions to which the Partner would otherwise be entitled in respect of the Redeemable Interests will accrue
or be made. 

  
 41 

 (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 Partnership Interests of the class to be so redeemed multiplied by the number of Partnership Interests of each such class included among the
Redeemable Interests. The redemption price shall be paid, as determined by the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption price, bearing interest at the rate of 5%
annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date. 
 (iii) The Partner or his 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 Partner at the place specified in the notice of redemption, of the Certificates 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 Partnership Interests. 
 (b) The provisions of this
Section 4.10 shall also be applicable to Partnership Interests held by a Partner as nominee 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 Partnership Interest before the redemption date if such transfer is otherwise
permitted under this Agreement. Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided the transferee of such Partnership Interest certifies to the satisfaction of the General Partner that he
is an Eligible Holder. If the transferee fails to make such certification, such redemption shall be effected from the transferee on the original redemption date.

Units issued upon conversion of Subordinated Units and (iii) Common Units issued pursuant to Section 5.11), the General Partner may, in order to maintain its Percentage Interest,
make additional Capital Contributions in an amount equal to the product obtained by multiplying (i)the quotient determined by dividing (A) the General Partner’s Percentage Interest immediately prior to the issuance of such Additional
Limited Partner Interests by the Partnership by (B) 100 less the General Partner’s Percentage Interest immediately prior to the issuance of such Additional Limited Partner Interests by the Partnership times (ii) the amount contributed
to the Partnership by the Limited Partners in exchange for such Additional Limited Partner Interests. Except as set forth in Article XII, the General Partner shall not be obligated to make any additional Capital Contributions to the
Partnership. 
 Section 5.3 Contributions by Limited Partners. 

(a) On the IPO Closing Date and pursuant to the Underwriting Agreement, each Underwriter shall contribute cash to the Partnership in
exchange for the issuance by the Partnership of Common Units to each Underwriter, as set forth in the Underwriting Agreement. 

(b) Upon the exercise, if any, of the Over-Allotment Option, each Underwriter shall contribute cash to the Partnership in exchange for
the issuance by the Partnership of Common Units to each Underwriter, all as set forth in the Underwriting Agreement. 
 (c) No
Limited Partner will be required to make any Capital Contribution to the Partnership pursuant to this Agreement. 

Section 5.4 Interest and Withdrawal of Capital Contributions. 

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 liquidation 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 in any
case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest a separate Capital Account
with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall 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 (other than Series A PIK Preferred Units)

  
 43 

 
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. For the avoidance of doubt, the Series A Preferred Units will be treated as a partnership interest in the Partnership that is “convertible equity” within the meaning of Treasury
Regulation Section 1.721-2(g)(3), and, therefore, each holder of a Series A Preferred Unit will be treated as a partner in the Partnership, other than with respect to the conversion feature of the Series A Preferred Unit. The initial Capital
Account balance in respect of each Series A Preferred Unit issued on the Series A Issuance Date shall be the Series A Issue Price, and the initial Capital Account balance in respect of each Series A PIK Preferred Unit shall be zero. After an
issuance of Series A PIK Preferred Units pursuant to Section 5.12(b)(ii), the Capital Accounts of all Series A Preferred Units that are Outstanding prior to such issuance shall be divided equally among all Series A Preferred Units that
are Outstanding after such issuance. The Capital Account balance of each holder of Series A Preferred Units in respect of its Series A Preferred Units shall not be increased or decreased as a result of the accrual and accumulation of an unpaid
distribution pursuant to Section 5.12(b)(ii)(A) or Section 5.12(b)(ii)(B) in respect of such Series A Preferred Units except as otherwise provided in this Agreement. 

(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 U.S. 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) of all
property owned by (x) any other Group Member that is classified as a partnership for U.S. federal income tax purposes and (y) any other partnership, limited liability company, unincorporated business or other entity classified as a
partnership for U.S. 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 and, as to those items described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without regard to
the fact that such items are not includable in gross income or are neither currently deductible nor capitalized for U.S. federal income tax purposes. 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. 

  
 44 

 (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) 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. 

(vi) 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) 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 Common Unit that has been issued upon conversion of a Subordinated 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
Section 5.5(c)(ii) apply), the Capital Account maintained for such Person with respect to its Subordinated Units or Common Units issued upon conversion of Subordinated Units will (A) first, be allocated to the Subordinated Units or
Common Units issued upon conversion of Subordinated Units to be transferred in an amount equal to the product of (x) the number of such Subordinated Units or Common Units issued upon conversion of 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 Subordinated Units or Common Units issued upon
conversion of Subordinated Units (“Retained Converted 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 Common Units
issued upon conversion of Subordinated Units will have a balance equal to the amount allocated under clause (A) hereinabove. 

  
 45 

 (iii) 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 shall (A) first, be allocated to IDR Reset Common Units in an amount equal to the product of (x) the Aggregate Quantity of IDR Reset Common Units and
(y) the Per Unit Capital Amount for an IPO Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the holder of the Incentive Distributions Rights. In the event that there is not a sufficient Capital
Account associated with the Incentive Distribution Rights to allocate the full Per Unit Capital Amount for an IPO Common Unit to the IDR Reset Common Units in accordance with clause (A) of this Section 5.5(c)(iii), the IDR Reset
Common Units shall be subject to Section 6.1(d)(x)(B) and Section 6.1(d)(x)(C). 

(d) (i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f), on (A) an issuance of
additional Partnership Interests for cash or other property, (B) the issuance of additional Partnership Interests for the provision of services, (C) the issuance by the Partnership of a “noncompensatory option” within the meaning
of Treasury Regulations Sections 1.721-2(f) and 1.761-3(b)(2) which is not treated as a partnership interest pursuant to Treasury Regulations Section 1.761-3(a) (other than an issuance of Series A PIK Preferred Units pursuant to
Section 5.12(b)(ii)), or (D) the conversion of a 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 shall be adjusted immediately prior to such event to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such
property for an amount equal to its fair market value immediately prior to such event and had been allocated 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. The General Partner shall adjust such Carrying Values in respect of the contributions that are made on the Closing Date. In determining such Unrealized Gain or Unrealized Loss, the aggregate cash
amount and fair market value of all Partnership assets immediately prior to such event shall be determined by the General Partner using such reasonable method of valuation as it may adopt (taking into account Section 7701(g) of the Code);
provided, however, that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership Interests of all Partners at such
time and must make such adjustments to such valuation as required by Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2). The General Partner shall allocate such aggregate value among the assets of the Partnership in such manner as it
determines in its discretion to be reasonable. 
 (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, as if such Unrealized Gain or Unrealized
Loss had been recognized in a sale of such property immediately prior to such distribution for an amount equal to its fair 

  
 46 

 
market value, and had been allocated to 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 assets (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 and allocated in the same manner as
that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined and allocated by the Liquidator using such method of valuation as it may adopt. 

(iii) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(s), immediately after the conversion of a Series A Preferred
Unit into Common Units in accordance with Section 5.12(b)(viii), the Capital Account of each Partner and the Carrying Value of each Partnership property shall be adjusted to reflect any Unrealized Gain or Unrealized Loss attributable to
such Partnership property, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property for an amount equal to its fair market value immediately after such conversion and (A) first, all Unrealized
Gain (if the Capital Account of each such Conversion Unit is less than the Per Unit Capital Account for a then Outstanding IPO Common Unit) or Unrealized Loss (if the Capital Account of each such Conversion Unit is greater than the Per Unit Capital
Account for a then Outstanding IPO Common Unit) had been allocated Pro Rata to each Partner holding Conversion Units received upon such conversion until the Capital Account of each such Conversion Unit is equal to the Per Unit Capital Amount for a
then Outstanding IPO Common Unit; and (B) second, any remaining Unrealized Gain or Unrealized Loss had been allocated to the Partners at such time pursuant to Section 6.1(c) and Section 6.1(d). In determining such
Unrealized Gain or Unrealized Loss, the aggregate cash amount and fair market value of all Partnership assets immediately after the conversion of a Series A Preferred Unit shall be determined by the General Partner using such reasonable method of
valuation as it may adopt (taking into account Section 7701(g) of the Code); provided, however, that the General Partner, in arriving at such valuation, must take fully into account the fair market value of the Partnership
Interests of all Partners at such time and must make such adjustments to such valuation as required by Treasury Regulation Section 1.704-1(b)(2)(iv)(h)(2). The General Partner shall allocate such aggregate value among the assets of the
Partnership in such manner as it determines in its discretion to be reasonable. If, after making the allocations of Unrealized Gain and Unrealized Loss as set forth above in this Section 5.5(d)(iii), the Capital Account of each Partner
with respect to each Conversion Unit received upon such conversion of the Series A Preferred Unit is less than the Per Unit Capital Amount for a then Outstanding IPO Common Unit, then Capital Account balances shall be reallocated between the
Partners holding Common Units (other than Conversion Units) and Partners holding Conversion Units so as to cause the Capital Account of each Partner holding a Conversion Unit to equal, on a per Unit basis with respect to each such Conversion Unit,
the Per Unit Capital Amount for a then Outstanding IPO Common Unit. 
 Section 5.6 Issuances of Additional
Partnership Interests. 
 (a) The Partnership may issue additional Partnership Interests and options, rights, warrants,
appreciation rights, tracking and phantom interests, and other economic interests relating to the Partnership Interests (including pursuant to Section 7.4(c)) 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. 

  
 47 

 (b) Each additional Partnership Interest or other security authorized to be issued by the
Partnership pursuant to Section 5.6(a) or Section 7.4(c) 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 or other securities), 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 (including
sinking fund provisions) or other security; (v) whether such Partnership Interest or other security 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 or other security 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 options, rights, warrants, appreciation rights, tracking and phantom interests, and other economic interests in the Partnership or relating to Partnership Interests pursuant to this Section 5.6 or
Section 7.4(c), (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) the admission of Additional
Limited Partners and (v) all additional issuances of Partnership Interests. The General Partner shall determine the relative rights, powers and duties of the holders of the Units or other Partnership Interests or other securities 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 other securities 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. 
 Section 5.7
Conversion of Subordinated Units. 
 (a) All of the Subordinated Units shall automatically convert into Common Units on a
one-for-one basis on the expiration or termination of the Subordination Period. 
 (b) A Common Unit that has been issued upon
conversion of a Subordinated Unit shall be subject to the provisions of Section 6.7. 

  
 48 

 Section 5.8 Limited Preemptive Right. 

Except as provided in this Section 5.8 and in Section 5.2 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 or other security, whether unissued, held in the treasury or hereafter created. The General Partner shall
have the right, that 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.
Any determination by the General Partner whether to exercise its right pursuant to the immediately preceding sentence shall be a determination made in its individual capacity and not as the general partner of the Partnership, and such determination
may be made in accordance with Section 7.9(c). 
 Section 5.9 Splits and Combinations. 

(a) Subject to Section 5.9(d), 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 and including the number of Common Units into which Series A Preferred Units may convert) are proportionately adjusted. 

(b) Whenever such a Pro Rata 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. 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 Notional 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 effective date for payment of
such distribution, subdivision or combination to maintain such Percentage Interest of the General Partner. 

  
 49 

 (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 such new Certificate or uncertificated Partnership Interests, 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 Notional 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 or fractional Notional General Partner Units but for the provisions of this Section 5.9(e), each fractional Unit or
fractional Notional General Partner Unit shall be rounded to the nearest whole Unit or Notional General Partner Unit (and a 0.5 Unit or Notional General Partner Unit shall be rounded to the next higher Unit or Notional 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 either or both of Sections 17-607 and 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, exercisable at its option at any time when there are no Subordinated Units Outstanding and the
Partnership has made a distribution pursuant to Section 6.4(c)(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 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 aggregate amount of 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 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 sentence have been satisfied. The Percentage Interest of the General Partner, with respect to the
General Partner Interest, after 

  
 50 

 
the issuance of the Aggregate Quantity of IDR Reset Common Units shall equal the Percentage Interest of the General Partner, with respect to the General Partner Interest, prior to the issuance of
the Aggregate Quantity of IDR Reset Common Units and the General Partner shall not be obligated to make any additional Capital Contribution to the Partnership in order to maintain its Percentage Interest in connection therewith and shall be issued
an additional number of Notional General Partner Units as is required to maintain such Percentage Interest. The making of the IDR Reset Election in the manner specified in Section 5.11(b) shall cause each of 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 on the basis specified above,
without any further approval required by the General Partner or the Unitholders, 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 number 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 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 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 a 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 (on terms acceptable to the National Securities Exchange upon
which the Common Units are then traded) of such Partnership Interests into Common Units within not more than 12 months following the Partnership’s receipt 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). 

  
 51 

 (e) The Target Distributions shall be adjusted at the time of the issuance of 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. 

Section 5.12 Establishment of Series A Preferred Units. 

(a) General. The Partnership hereby designates and creates a series of Units to be designated as “Series A Convertible
Preferred Units” and consisting of a total of 5,142,857 Series A Preferred Units, plus any additional Series A Preferred Units issued in kind as a distribution pursuant to Section 5.12(b)(ii) (“Series A PIK
Preferred Units”, and together with such Series A Convertible Preferred Units issued on the Series A Issuance Date, the “Series A Preferred Units”), having the same rights, preferences and privileges, and subject
to the same duties and obligations, as the Common Units, except as set forth in this Section 5.12 and in Sections 5.5(d)(i), 6.10 and 12.9. Other than with respect to Series A PIK Preferred Units, immediately
following the Series A Issuance Date and thereafter no additional Series A Preferred Units shall be designated, created or issued without the prior written approval of the General Partner and the holders of a majority of the Outstanding Series A
Preferred Units. 
 (b) Rights of Series A Preferred Units. The Series A Preferred Units shall have the following rights,
preferences and privileges and shall be subject to the following duties and obligations: 
 (i) Allocations. 

(A) Notwithstanding anything to the contrary in Section 6.1(a), (x) following any allocation made
pursuant to Section 6.1(a)(i) and prior to any allocation made pursuant to Section 6.1(a)(ii), any Net Income shall be allocated to all Unitholders holding Series A Preferred Units, Pro Rata, until the aggregate of the Net
Income allocated to such Unitholders pursuant to this Section 5.12(b)(i)(A) for the current and all previous taxable periods since issuance of the Series A Preferred Units is equal to the aggregate amount of cash distributed with respect
to such Series A Preferred Units for the current and previous taxable periods and (y) in no event shall any Net Income be allocated pursuant to Section 6.1(a)(ii) in respect of Series A Preferred Units. 

(B) Notwithstanding anything to the contrary in Section 6.1(b), (x) Unitholders holding Series A
Preferred Units shall not receive any allocation pursuant to Section 6.1(b)(i) with respect to their Series A Preferred Units, and (y) following any allocation made pursuant to Section 6.1(b)(i) and prior to any
allocation made pursuant to Section 6.1(b)(ii), Net Losses shall be allocated to all Unitholders holding Series A Preferred Units, Pro Rata, until the Adjusted Capital Account of each such Unitholder in respect of each Outstanding Series
A Preferred Unit has been reduced to zero. 

  
 52 

 (C) Notwithstanding anything to the contrary in
Section 6.1(c)(i), (x) Unitholders holding Series A Preferred Units shall not receive any allocation pursuant to Section 6.1(c)(i) with respect to their Series A Preferred Units, but (y) following any allocation
made pursuant to Section 6.1(c)(i)(A) and prior to any allocation made pursuant to Section 6.1(c)(i)(B), any remaining Net Termination Gain shall be allocated to all Unitholders holding Series A Preferred Units, Pro Rata,
until the Capital Account in respect of each Outstanding Series A Preferred Unit is equal to the Series A Liquidation Value. 
 (D) Notwithstanding anything to the contrary in Section 6.1(c)(ii), (x) Unitholders holding Series A Preferred Units shall not receive any allocation pursuant to
Section 6.1(c)(ii) with respect to their Series A Preferred Units, and (y) following the allocations made pursuant to Section 6.1(c)(ii)(C), and prior to any allocation made pursuant to Section 6.1(c)(ii)(D),
any remaining Net Termination Loss shall be allocated to all Unitholders holding Series A Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series A Preferred Unit has been reduced to zero. 

(ii) Distributions. 
 (A) Commencing with the Quarter ending on June 30, 2013, the holders of the Series A Preferred Units as of an applicable Record Date shall be entitled to receive cumulative distributions (each, a
“Series A Quarterly Distribution”), prior to any other distributions made in respect of any other Partnership Interests pursuant to Section 6.4 or Section 6.5, in the amount set forth in this
Section 5.12(b)(ii)(A) in respect of each Outstanding Series A Preferred Unit. All such distributions shall be paid Quarterly within forty-five (45) days after the end of each Quarter (each such payment date, a “Series A
Distribution Payment Date”). For the Quarter ending June 30, 2013, and for each Quarter thereafter through and including the Quarter ending immediately prior to the Coupon Conversion Quarter, the Series A Quarterly Distribution on
each Outstanding Series A Preferred Unit shall be paid as follows: (i) a number of Series A PIK Preferred Units equal to the Series A PIK Payment Amount and (ii) $0.25 in cash (provided that for the Quarter in which the Series A Issuance
Date occurs, the amount payable pursuant to this clause (ii) shall be an amount in cash equal to the product of (I) $0.25 times (II) a fraction, of which the numerator is the number of days from and including the Series A Issuance Date to
but excluding the date of such Quarter’s end, and the denominator is 91). With respect to the Coupon Conversion Quarter and all Quarters thereafter, the Series A Quarterly Distributions shall be paid entirely in cash at the Series A
Distribution Rate. Notwithstanding anything to the contrary in this Agreement, if the Partnership elects to reduce the distribution payable on the Series A Preferred 

  
 53 

 
Units in respect of any of the Quarters ended June 30, 2013, September 30, 2013 and December 31, 2013 in order to comply with Section 7.06 of the New Credit Agreement, as
amended, including by the Fourth Amendment, then, notwithstanding anything to the contrary in this Agreement, no part of such reduction shall (i) constitute Series A Unpaid Cash Distributions, (ii) accrue or accumulate in any manner
hereunder or (iii) bear interest pursuant to Section 5.12(b)(ii)(C) or otherwise. If the Partnership establishes a Record Date for any distribution to be made by the Partnership on other Partnership Interests pursuant to Sections
6.4 or Section 6.5, then the Record Date established pursuant to this Section 5.12(b)(ii) for a Series A Quarterly Distribution in respect of any Quarter shall be the same Record Date established for any distribution to
be made by the Partnership in respect of distributions on other Partnership Interests pursuant to Sections 6.4 or Section 6.5 for such Quarter. Unless otherwise expressly provided, references in this Agreement to Series A
Preferred Units shall include all Series A PIK Preferred Units Outstanding as of the date of such determination. 

(B) When any Series A PIK Preferred Units are payable to a Record Holder of Series A Preferred Units pursuant to this
Section 5.12, the Partnership shall issue the Series A PIK Preferred Units to such Record Holder no later than the Series A Distribution Payment Date (the date of issuance of such Series A PIK Preferred Units, the “Series A
PIK Preferred Payment Date”). On the Series A PIK Preferred Payment Date, the Partnership shall issue to such Series A Unitholder a Certificate or Certificates for the number of Series A PIK Preferred Units to which such Series A
Unitholder shall be entitled. The issuance of the Series A PIK Preferred Units pursuant to this Section 5.12(b)(ii) shall be deemed to have been made on the first day of the Quarter following the Quarter in respect of which such payment
of Series A PIK Preferred Units was due. Prior to the Coupon Conversion Quarter, if, in violation of this Agreement, the Partnership fails to pay in full any Series A Quarterly Distribution in kind when due, then the holders entitled to the unpaid
Series A PIK Preferred Units shall be entitled (I) to Series A Quarterly Distributions in subsequent Quarters, (II) to receive the Series A Liquidation Value in accordance with Section 5.12(b)(iv) in respect of such Series A PIK
Preferred Units, and (III) to all other rights under this Agreement as if such unpaid Series A PIK Preferred Units had in fact been distributed on the date due. Nothing in this Section 5.12(b)(ii)(B) shall alter the obligation of the
Partnership to pay any unpaid Series A PIK Preferred Units or the right of the holders of Series A Preferred Units to enforce this Agreement to compel the Partnership to distribute any unpaid Series A PIK Preferred Units. Fractional Series A PIK
Preferred Units shall not be issued to any person (each fractional Series A PIK Preferred Unit shall be rounded to the nearest whole Series A PIK Preferred Unit (and a 0.5 Series A PIK Preferred Unit shall be rounded up to the next higher Series A
PIK Preferred Unit)). 
 (C) Beginning with the Coupon Conversion Quarter, if in violation of this Agreement, the
Partnership fails to pay in full any Series A Quarterly Distribution when due, then, without limiting any rights of the holders of the Series A Preferred Units to compel the Partnership to make such distribution,

  
 54 

 
from and after the first date of such failure and continuing until such failure is cured by payment in full in cash of all arrearages with respect to any Series A Quarterly Distribution,
including accrued but unpaid interest thereon, (w) the amount of such unpaid distributions (“Series A Unpaid Cash Distributions”) will accrue and accumulate from and including the first day of the Quarter immediately
following the Quarter in respect of which such payment is due until paid in full, (x) any Series A Unpaid Cash Distribution shall accrue interest from the applicable Series A Distribution Payment Date at rate equal to 6.0% per annum, and
(y) the Partnership shall not be permitted to, and shall not, declare or make (i) any distributions in respect of any Junior Interests and (ii) any distributions in respect of any Series A Parity Securities. 

(D) If all or any portion of a Series A Quarterly Distribution is to be paid in cash, then the aggregate amount of such
cash to be so distributed in respect of the Series A Preferred Units Outstanding as of the Record Date for such Series A Quarterly Distribution shall be paid out of Available Cash prior to making any distribution pursuant to Sections 6.4 or
6.5. To the extent that any portion of a Series A Quarterly Distribution to be paid in cash with respect to any Quarter exceeds the amount of Available Cash for such Quarter, an amount of cash equal to the Available Cash for such Quarter will
be paid to the Series A Unitholders Pro Rata and the balance of such Series A Quarterly Distribution shall be unpaid and shall constitute an arrearage and accrue interest as set forth in Section 5.12(b)(ii)(C). The Partnership shall
provide written notice to the Series A Unitholders, not later than the last Business Day of the month immediately following the end of such Quarter, describing in reasonable detail the Partnership’s calculation of Available Cash for such
Quarter and the portion, if any, of the Series A Quarterly Distribution the Partnership will be unable to pay on the applicable Series A Distribution Payment Date. 

(E) Notwithstanding anything in this Section 5.12(b)(ii) to the contrary, with respect to Series A Preferred
Units that are converted into Common Units, the holder thereof shall not be entitled to a Series A Preferred Unit distribution and a Common Unit distribution with respect to the same period, but shall be entitled only to the distribution to be paid
based upon the class of Units held as of the close of business on the applicable Record Date. For the avoidance of doubt, if a Series A Conversion Notice Date occurs prior to the close of business on a Record Date for payment of a distribution on
the Common Units, the applicable holder of Series A Preferred Units shall receive only the Common Unit distribution with respect to such period. 
 (F) Notwithstanding anything in Article VI to the contrary, neither the General Partner nor the holders of Incentive Distribution Rights shall be entitled to receive distributions or allocations of
income or gain that correspond or relate to amounts distributed or allocated to Unitholders in respect of Series A Preferred Units, regardless of whether the amounts so distributed or allocated in respect of the Series A Preferred Units were
determined under clause (ii) of the definition of “Series A Distribution Rate” or were otherwise determined on an “as converted” basis. 

  
 55 

 (iii) Issuance of Series A Preferred Units. The Series A Preferred Units (excluding
Series A PIK Preferred Units) shall be issued by the Partnership pursuant to the terms and conditions of the Contribution Agreement. 
 (iv) Liquidation Value. In the event of any liquidation, dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange or other disposition of all or
substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series A Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or
any assignees, prior and in preference to any distribution of any assets of the Partnership to the Record Holders of any other class or series of Partnership Interests, the positive value in each such holder’s Capital Account in respect of such
Series A Preferred Units. If in the year of such liquidation and winding up, or sale, exchange or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in respect of such Series
A Preferred Units is less than the aggregate Series A Liquidation Value of such Series A Preferred Units, then notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for
such year and prior to any distribution pursuant to the preceding sentence, items of gross income and gain shall be allocated to all Unitholders then holding Series A Preferred Units, Pro Rata, until the Capital Account in respect of each
Outstanding Series A Preferred Unit is equal to the Series A Liquidation Value (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such liquidation, dissolution or winding up any such
Record Holder’s Capital Account in respect of such Series A Preferred Units is less than the aggregate Series A Liquidation Value of such Series A Preferred Units after the application of the preceding sentence, then to the extent permitted by
applicable law and notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable period(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership
shall be reallocated to all Unitholders then holding Series A Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series A Preferred Unit after making allocations pursuant to this and the immediately preceding
sentence is equal to the Series A Liquidation Value (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). At such time as such allocations have been made to the Outstanding Series A Preferred Units, any
remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to
Section 17-804 of the Delaware Act, the Record Holders of the Series A Preferred Units shall become entitled to receive any distributions in respect of the Series A Preferred Units that are accrued and unpaid as of the date of such distribution
in priority over any entitlement of any other Partners or Assignees with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability
for any obligations with respect to such distributions to any Record Holder(s) of Series A Preferred Units. 

  
 56 

 (v) Voting Rights. 

(A) Except as provided in Section 5.12(b)(v)(B) below, the Outstanding Series A Preferred Units shall have
voting rights that are identical to the voting rights of the Common Units and shall vote with the Common Units as a single class, so that each Outstanding Series A Preferred Unit will be entitled to one vote for each Common Unit into which such
Series A Preferred Unit is then convertible on each matter with respect to which each Common Unit is entitled to vote. Each reference in this Agreement to a vote of Record Holders of Common Units shall be deemed to be a reference to the holders of
Common Units and Series A Preferred Units on an “as if” converted basis, and the definition of “Unit Majority” shall correspondingly be construed to mean at least a majority of the Common Units and the Series A Preferred
Units, on an “as if” converted basis, voting together as a single class during any period in which any Series A Preferred Units are Outstanding. 
 (B) Notwithstanding any other provision of this Agreement, in addition to all other requirements imposed by Delaware law, and all other voting rights granted under this Agreement, the affirmative vote of
the Record Holders of a majority of the Outstanding Series A Preferred Units, voting separately as a class based upon one vote per Series A Preferred Unit, shall be necessary on any matter (including a merger, consolidation or business combination)
that adversely affects any of the rights, preferences and privileges of the Series A Preferred Units or amends or modifies any of the terms of the Series A Preferred Units; provided that the Partnership shall be able to amend this
Section 5.12 without the approval by the Record Holders of Outstanding Series A Preferred Units so long as the amendment does not adversely affect the holders of the Series A Preferred Units in any material respect and does not affect
the holders of the Series A Preferred Units disproportionately in relation to the holders of Common Units; provided, however, that the Partnership may, without the consent or approval of the Record Holders of Outstanding Series A
Preferred Units, create (by reclassification or otherwise) and issue Junior Interests (including by amending the provisions of any existing class of Partnership Interests to make such class of Partnership Interests a class of Junior Interests) in an
unlimited amount. Without limiting the generality of the preceding sentence, any action shall be deemed to adversely affect the holders of the Series A Preferred Units in a material respect if such action would: 

 

	 	(1)	reduce the Series A Distribution Rate, change the form of payment of distributions on the Series A Preferred Units, defer the date from which distributions on the
Series A Preferred Units will accrue, cancel accrued and unpaid distributions on the Series A Preferred Units or any interest accrued thereon, or change the seniority rights of the Series A Unitholders as to the payment of distributions in relation
to the Unitholders of any other class or series of Units or, except as determined to be appropriate in connection with the issuance of Junior Interests, amend this Section 5.12; 

  
 57 

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

  

	 	(3)	make the Series A Preferred Units redeemable or convertible at the option of the Partnership; or 

 

	 	(4)	result in a Series A Change of Control. 

 (vi) No Series A Parity Securities or Series A Senior Securities. Other than Series A PIK Preferred Units issued in connection with the Series A Quarterly Distribution, the Partnership shall not,
without the affirmative vote of the holders of a majority of the Outstanding Series A Preferred Units, issue any Series A Parity Securities or Series A Senior Securities. 
 (vii) Certificates. 
 (A) The Series A Preferred Units shall
be evidenced by Certificates in such form as the General Partner may approve and, subject to the satisfaction of any applicable legal, regulatory and contractual requirements, may be assigned or transferred in a manner identical to the assignment
and transfer of other Units; unless and until the General Partner determines to assign the responsibility to another Person, the Partnership will act as the registrar and transfer agent for the Series A Preferred Units. The Certificates evidencing
Series A Preferred Units shall be separately identified and shall not bear the same CUSIP number as the Certificates evidencing Common Units. 
 (B) The certificate(s) representing the Series A Preferred Units may be imprinted with a legend in substantially the following form: 

“NEITHER THE OFFER NOR SALE OF THESE SECURITIES HAS BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THESE SECURITIES
MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION THEREUNDER AND, IN THE CASE OF A TRANSACTION
EXEMPT FROM REGISTRATION, UNLESS SOLD PURSUANT TO RULE 144 UNDER SUCH ACT OR THE PARTNERSHIP HAS RECEIVED DOCUMENTATION REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER SUCH ACT. THIS SECURITY IS SUBJECT TO
CERTAIN RESTRICTIONS ON TRANSFER SET FORTH IN THE THIRD AMENDED AND RESTATED LIMITED PARTNERSHIP AGREEMENT OF THE PARTNERSHIP, DATED AS OF APRIL 15, 2013, A COPY OF WHICH MAY BE OBTAINED FROM THE PARTNERSHIP AT ITS PRINCIPAL EXECUTIVE OFFICES.”

  
 58 

 (viii) Conversion. 

(A) At the Option of the Series A Unitholder. At any time and from time to time after January 1, 2014 or such
earlier time if consented to in writing by the required lenders under the New Credit Agreement, the Series A Preferred Units owned by any Series A Unitholder shall be convertible, in whole or in part, upon the request of the Series A Unitholder into
a number of Common Units determined by multiplying the number of Series A Preferred Units to be converted by the Series A Conversion Rate. Immediately upon any conversion of Series A Preferred Units, all rights of the Converting Unitholder in
respect thereof shall cease, including, without limitation, any accrual of distributions, and such Converting Unitholder shall be treated for all purposes as the owner of Common Units. Fractional Common Units shall not be issued to any person
pursuant to this Section 5.12(b)(viii)(A) (each fractional Common Unit shall be rounded to the nearest whole Common Unit (and a 0.5 Common Unit shall be rounded up to the next higher Common Unit)). 

(B) Conversion Notice. To convert Series A Preferred Units into Common Units pursuant to
Section 5.12(b)(viii)(A), the Converting Unitholder shall give written notice (a “Series A Conversion Notice”) to the Partnership in the form of Exhibit C attached hereto stating that such Series A
Unitholder elects to so convert Series A Preferred Units and shall state therein with respect to Series A Preferred Units to be converted pursuant to Section 5.12(b)(viii)(A) the following: (a) the number of Series A Preferred
Units to be converted, (b) the Certificate(s) evidencing the Series A Preferred Units to be converted and duly endorsed, (c) the name or names in which such Series A Unitholder wishes the Certificate or Certificates for Conversion Units to
be issued, and (d) such Series A Unitholder’s computation of the number of Conversion Units to be received by such Series A Unitholder (or designated recipient(s)) upon the Series A Conversion Date. The date any Series A Conversion Notice
is received by the Partnership shall be hereinafter be referred to as a “Series A Conversion Notice Date.” 
 (C) Timing; Certificates. If a Series A Conversion Notice is delivered by a Series A Unitholder to the Partnership in accordance with Section 5.12(b)(viii)(B), the Partnership shall
issue the Conversion Units no later than seven (7) days after a Series A Conversion Notice Date (any date of issuance of such Common Units, a “Series A Conversion Date”). On the Series A Conversion Date, the Partnership
shall issue to such Series A Unitholder (or designated recipient(s)) a Certificate or Certificates for the number of Conversion Units to which such holder shall be entitled. In lieu of delivering physical Certificates representing the Conversion
Units issuable upon conversion of Series A Preferred Units, provided the Transfer Agent is participating in the Depository’s Fast Automated Securities Transfer program, upon request of the

  
 59 

 
Series A Unitholder, the Partnership shall use its commercially reasonable efforts to cause its Transfer Agent to electronically transmit the Conversion Units issuable upon conversion or
distribution payment to such Series A Unitholder (or designated recipient(s)), by crediting the account of the Series A Unitholder (or designated recipient(s)) prime broker with the Depository through its Deposit Withdrawal Agent Commission system.
The parties agree to coordinate with the Depository to accomplish this objective. Upon issuance of Conversion Units to the Converting Unitholder, all rights under the converted Series A Preferred Units shall cease, and such Converting Unitholder
shall be treated for all purposes as the Record Holder of such Conversion Units. 
 (D) Distributions,
Combinations, Subdivisions and Reclassifications by the Partnership. If the Partnership (i) makes a distribution on its Common Units in Common Units, (ii) subdivides or splits its outstanding Common Units into a greater number of
Common Units, (iii) combines or reclassifies its Common Units into a smaller number of Common Units or (iv) issues by reclassification of its Common Units any Partnership Interests (including any reclassification in connection with a
merger, consolidation or business combination in which the Partnership is the surviving Person), then the Series A Conversion Rate in effect at the time of the Record Date for such distribution or the effective date of such subdivision, split,
combination, or reclassification shall be proportionately adjusted so that the conversion of the Series A Preferred Units after such time shall entitle each Series A Unitholder to receive the aggregate number of Common Units (or any Partnership
Interests into which such Common Units would have been combined, consolidated, merged or reclassified pursuant to clauses (iii) and (iv) above) that such Series A Unitholder would have been entitled to receive if the Series A Preferred
Units had been converted into Common Units immediately prior to such Record Date or effective date, as the case may be, and in the case of a merger, consolidation or business combination in which the Partnership is the surviving Person, the
Partnership shall provide effective provisions to ensure that the provisions in this Section 5.12 relating to the Series A Preferred Units shall not be abridged or amended and that the Series A Preferred Units shall thereafter retain the
same powers, preferences and relative participating, optional and other special rights, and the qualifications, limitations and restrictions thereon, that the Series A Preferred Units had immediately prior to such transaction or event. An adjustment
made pursuant to this Section 5.12(b)(viii)(E) shall become effective immediately after the Record Date in the case of a distribution and shall become effective immediately after the effective date in the case of a subdivision,
combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Partnership is the surviving Person) or split. Such adjustment shall be made successively whenever any
event described above shall occur. 
 If, in the future, the Partnership issues any options, warrants, or other
rights to purchase Common Units, or Partnership Interests exercisable or convertible into or exchangeable for Common Units (or options, warrants, or other rights to 

  
 60 

 
purchase any such Partnership Interests that are exercisable or convertible into or exchangeable for Common Units) other than any such options, warrants or other rights issued pursuant to any
Long Term Incentive Plan (herein collectively, “Convertible Securities”), the General Partner shall, at the direction and at the option of the holders of a majority of the Outstanding Series A Preferred Units in their sole
discretion, either (i) amend the provisions of this Agreement relating to antidilution protection to (A) revise any such provision that is less favorable than the corresponding provision offered in the terms of such Convertible Securities
(or any related purchase agreement) so that such provision is the same as such provision offered in the terms of such Convertible Securities (or any related purchase agreement) and (B) incorporate any provision(s) offered in the terms of such
Convertible Securities (or any related purchase agreement) that is not currently provided for in this Agreement and which would make the antidilution protection provisions of this Agreement more favorable to the holders of Series A Preferred Units,
which amendment shall be effective concurrently with the issuance and/or execution of documentation relating to such Convertible Securities, or (ii) retain the antidilution language applicable to the Series A Preferred Units at such time. The
Partnership agrees to provide as much prior notice of the proposed issuance of any such Convertible Securities and/or execution of documentation relating to such issuance of Convertible Securities as is reasonably practicable (and in any event, such
notice shall be provided at least ten (10) Business Days prior to such issuance and/or execution). 
 (E)
Follow-On Adjustments. If the Partnership shall issue or sell, or grant any Common Units or Convertible Securities at an indicative per Common Unit price (the “Follow-On Price”, and such Common Units or Convertible
Securities so issued, sold or granted, on an as-converted basis, the “Follow-On Units”) that is less than one hundred percent (100%) of the Series A Adjusted Issue Price, then the Series A Conversion Rate will be reset
so that it will equal the price determined according to the following formula: 
 ((CP x OB) + (FP x Q)) / OA

 Where: 
 CP = the Series A Conversion Rate in effect immediately before the issuance of the Follow-On Units 
 FP = the Follow-On Price 
 OB = the total number of fully diluted
Common Units outstanding before the issuance of the Follow-On Units 
 Q = the total number of fully diluted
Follow-On Units issued 

  
 61 

 OA = the total number of fully diluted Common Units outstanding after giving
effect to the issuance of the Follow-On Units. 
 For purposes of this Section 5.12(b)(viii)(E), the
indicative price per Common Unit resulting from the issuance of Convertible Securities will be determined using the principles set forth in Section 5.12(b)(viii)(H)(c). 

(F) Other Extraordinary Transactions Affecting the Partnership. 

a. Prior to the consummation of any recapitalization, reorganization, consolidation, merger, spin-off or other business
combination (not otherwise addressed in Section 5.12(b)(viii)(D) above) in which the holders of Common Units are to receive securities, cash or other assets (a “Partnership Event”), the Partnership shall, as
promptly as practicable, but in any event no later than twelve (12) Business Days prior to the consummation of the Partnership Event, make an irrevocable written offer, subject to consummation of the Partnership Event, a
(“Partnership Event Change of Control Offer”) to each holder of Series A Preferred Units to redeem all (but not less than all) of such holder’s Series A Preferred Units for a price per Series A Preferred Unit payable in
cash equal to the greater of (x) the Series A Liquidation Value for each Series A Preferred Unit and (y) an amount equal to the product of (1) the number of Common Units into which each Series A Preferred Unit is convertible pursuant
to Section 5.12(b)(viii) on the day immediately prior to the date of the Partnership Event Change of Control Offer and (2) the sum of (A) the cash consideration per Common Unit to be paid to the holders of Common Units pursuant
to the Partnership Event plus (B) the fair market value per Common Unit of the securities or other assets to be distributed to the holders of the Common Units pursuant to the Partnership Event (as applicable, the “Partnership Event
Payment”). 
 b. Upon receipt by a Series A Unitholder of a Partnership Event Change of Control
Offer, such Series A Unitholder may elect, by written notice received by the Partnership no later than five (5) Business Days after the receipt by such holder of a Partnership Event Change of Control Offer, to receive Survivor Preferred
Securities (as defined below) pursuant to this Section 5.12(b)(viii)(F)(b) in lieu of a Partnership Event Payment. Upon receipt of such Series A Unitholder’s election to receive Survivor Preferred Securities, the Partnership shall
as promptly as practicable, but in any event prior to the consummation of any Partnership Event, make appropriate provision to ensure that such electing holders of Series A Preferred Units receive in such Partnership Event a preferred security,
issued by the Person surviving or resulting from such Partnership Event and containing provisions substantially equivalent to the provisions set forth in this Agreement with respect to the Series A Preferred Units, including Section 5.12
and Section 7.3 hereof, without material abridgement, including, without limitation, the same powers, preferences, rights to distributions, rights to accumulation and compounding upon failure to pay distributions, and relative
participating, optional or other special rights and the qualifications, limitations or restrictions thereon, that the Series A Preferred Unit 

  
 62 

 
had immediately prior to such Partnership Event (the “Survivor Preferred Security”). The Series A Conversion Rate in effect at the time of the effective date of such
Partnership Event shall be proportionately adjusted so that the conversion of a unit of Survivor Preferred Security after such time shall entitle the holder to the number of securities or amount of cash or other assets which, if a Series A Preferred
Unit had been converted into Common Units immediately prior to such Partnership Event, such holder would have been entitled to receive immediately following such Partnership Event. Subsequent adjustments to the Conversion Price of the Survivor
Preferred Security shall be made successively thereafter whenever any event described in Section 5.12(b)(viii)(D), Section 5.12(b)(viii)(E) or this Section 5.12(b)(viii)(F) shall occur. Notwithstanding the
foregoing, the Partnership may consummate a Partnership Event without making appropriate provision to ensure that the holders of Series A Preferred Units receive a Partnership Event Payment or Survivor Preferred Security, as applicable, with respect
to such Partnership Event if prior to such consummation the Partnership has received the prior written approval of the holders of a majority of the Outstanding Series A Preferred Units. 

c. A Partnership Event Change of Control Offer shall be mailed to each Series A Unitholder and shall describe the
transaction or transactions that constitute the Partnership Event and state: 
 i. that the Partnership Event
Change of Control Offer is being made pursuant to this Section 5.12(b)(viii)(F) and that the Partnership is making an offer to redeem all Series A Preferred Units of such Unitholder (subject to the consummation of the Partnership Event);

 ii. the amount of the Partnership Event Payment and the redemption date, which shall be the date on which the
Partnership Event is consummated or as soon thereafter as practicable (the “Partnership Event Payment Date”); and 
 iii. the amount per Common Unit that each Common Unitholder is receiving in connection with the Partnership Event. 
 On the Partnership Event Payment Date, the Partnership (or its successor) shall pay to each Unitholder of Series A Preferred Units that accepts the Partnership Event Change of Control Offer an amount in
cash equal to such holder’s applicable Partnership Event Payment, and all of such holder’s rights and privileges under the Series A Preferred Units or as a Series A Unitholder shall be extinguished. 

(G) Notwithstanding any of the other provisions of this Section 5.12(b)(viii), no adjustment shall be made to
the Series A Conversion Rate pursuant to Section 5.12(b)(viii)(D)-(F) as a result of any of the following: 

  
 63 

 a. the grant of Common Units or options, warrants or rights to purchase
Common Units or the issuance of Common Units upon the exercise of any such options, warrants or rights to employees, officers or directors of the General Partner or the Partnership and its Subsidiaries in respect of services provided to or for the
benefit of the Partnership or its Subsidiaries, under compensation plans and agreements approved in good faith by the General Partner (including any Long Term Incentive Plan); provided that, in the case of options, warrants or rights to
purchase Common Units, the exercise price per Common Unit shall not be less than the Closing Price on the date such option, warrant or other right is issued; 
 b. the issuance of any Common Units as all or part of the consideration to effect (i) the closing of any acquisition by the Partnership of assets of an unrelated third party in an arm’s-length
transaction or (ii) the consummation of a merger, consolidation or other business combination of the Partnership with or into another entity to the extent such transaction(s) is or are validly approved by the vote or consent of the General
Partner; and 
 c. the issuance of Partnership Interests for which an adjustment is made under another provision
of this Section 5.12(b)(viii). 
 (H) The following rules shall apply for purposes of this
Section 5.12(b)(viii): 
 a. In the case of the issuance or sale (or deemed issuance or sale) of
Common Units for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any reasonable underwriting discounts or placement agent fees, commissions or the expenses allowed, paid or incurred by the Partnership
for any underwriting or placement agent or otherwise in connection with the issuance and sale thereof. 
 b. In
the case of the issuance or sale (or deemed issuance or sale) of Common Units for consideration in whole or in part other than cash, the consideration other than cash shall be valued at the Agreed Value thereof; 

c. In the case of the issuance or sale of Convertible Securities, the following provisions shall apply for all purposes of
this Section 5.12(b)(viii)(H): 
  

	 	i.	The aggregate maximum number of Common Units deliverable upon exercise (assuming the satisfaction of any conditions to exercisability, including, without limitation,
the passage of time, but without taking into account potential antidilution adjustments) of options or warrants to purchase or rights to subscribe for Common Units shall be deemed to have been issued at the time such options, warrants or rights were
issued and for consideration equal to the consideration (determined in the manner provided in this Section 5.12(b)(viii)(H)), if any, received by the Partnership upon the issuance of such options, warrants or rights plus the minimum
exercise price provided in such options, warrants or rights (without taking into account potential antidilution adjustments) for the Common Units covered thereby. 

  
 64 

	 	ii.	The aggregate maximum number of Common Units deliverable upon conversion of or in exchange (assuming the satisfaction of any conditions to convertibility or
exchangeability, including, without limitation, the passage of time, but without taking into account potential antidilution adjustments) for any such convertible or exchangeable securities or upon the exercise of options or warrants to purchase or
rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options, warrants or rights were issued and for a
consideration equal to the consideration, if any, received by the Partnership for any such securities or options, warrants or rights, plus the minimum additional consideration, if any, to be received by the Partnership (without taking into account
potential antidilution adjustments) upon the conversion or exchange of such securities or upon the exercise of such options, warrants or rights and subsequent conversion or exchange of the underlying convertible or exchangeable securities, as
appropriate (the consideration in each case to be determined in the manner provided in this Section 5.12(b)(viii)). 

  

	 	iii.	In the event of any change in (x) the number of Common Units deliverable or (y) the consideration payable to the Partnership upon exercise of such options,
warrants or rights with respect to either Common Units or such convertible or exchangeable securities or upon conversion of or in exchange for such convertible or exchangeable securities and not otherwise entitled to any appropriate antidilution
adjustment pursuant to this Section 5.12, including, but not limited to, a change resulting from the antidilution provisions thereof, the Series A Conversion Rate, to the extent in any way affected by or computed using such options,
warrants, rights or securities, shall be recomputed to reflect such change, but no further adjustment shall be made for the actual issuance of Common Units or any payment of such consideration upon the exercise of any such options, warrants or
rights or the conversion or exchange of such securities. 

  

	 	iv.	 Upon the expiration of any such options, warrants or rights with respect to either Common Units or such convertible or exchangeable securities or the
termination of any such rights to convert or exchange, the Series A Conversion Rate, to the extent in any way affected by or computed using such options, warrants, 

  
 65 

	 	
rights or securities shall be recomputed to reflect the issuance of only the number of Common Units actually issued upon the exercise of such options, warrants or rights with respect to Common
Units, upon the conversion or exchange of such securities, or the number of Common Units issuable upon conversion or exchange of the convertible or exchangeable securities that were actually issued upon exercise of options, warrants or rights
related to such securities. 

  

	 	v.	The number of Common Units deemed issued and the consideration deemed paid therefor pursuant to Sections 5.12(b)(viii)(H)(c)(i) and (ii) shall
be appropriately adjusted to reflect any change, termination or expiration of the type described in either Section 5.12(b)(viii)(H)(c)(iii) or (iv). 

d. Notwithstanding any of the other provisions of this Section 5.12(b)(viii)(H), no adjustment shall be made
to the number of Common Units issuable upon conversion of the Series A Preferred Units or the Series A Conversion Rate as a result of an event for which an adjustment is made under another provision of this Section 5.12(b)(viii)(H).

 e. For purposes of this Section 5.12(b)(viii), no adjustment to the Series A Conversion Rate shall
be made in an amount less than 1/100th of one cent per Unit; provided that any adjustments that are not required to be made by reason of this sentence shall be carried forward and shall be taken into account in any subsequent adjustment made.

 (I) In the event of any taking by the Partnership of a Record Date of the holders of any class of Partnership
Interests for the purpose of determining the holders thereof who are entitled to receive any distribution thereon, any security or right convertible into or entitling the holder thereof to receive additional Common Units, or any right to subscribe
for, purchase or otherwise acquire any Partnership Interests or any other securities or property of the Partnership, or to receive any other right, the Partnership shall notify each holder of Series A Preferred Units at least fifteen (15) days
prior to the Record Date, of which any such Record Date is to be taken for the purpose of such distribution, security or right and the amount and character of such distribution, security or right; provided, however, that the foregoing
requirement shall be deemed satisfied with respect to any holder of Series A Preferred Units if at least fifteen (15) days prior to the Record Date, the Partnership shall have issued a press release which shall be posted on the
Partnership’s website and carried by one or more wire services, containing the required information. 
 (J)
The Partnership shall pay any and all issue, documentary, stamp and other taxes, excluding any income, franchise, property or similar taxes, that may be payable in respect of any issue or delivery of Conversion Units on conversion of, or payment of
distributions on, Series A Preferred Units pursuant 

  
 66 

 
hereto. However, the holder of any Series A Preferred Units shall pay any tax that is due because the Conversion Units issuable upon conversion thereof or distribution payment thereon are issued
in a name other than such Series A Unitholder’s name. 
 (K) The Partnership agrees that it will act in good
faith to make any adjustment(s) required by this Section 5.12(b)(viii) equitably and in such a manner as to afford the Series A Unitholders the benefits of the provisions hereof, and will not take any action that could reasonably be
expected to deprive such Series A Unitholders of the benefit hereof. 
 (ix) Remarketing. If any Series A Unitholder
approaches the Partnership with a desire to sell more than 250,000 Series A Preferred Units, or Conversion Units underlying such Series A Preferred Units having equivalent economic value (based on the sum of the Series A Issue Price of the Series A
Preferred Units and all accrued and accumulated but unpaid distributions on such Series A Preferred Units), the Partnership shall, upon the request of such Series A Unitholder, cooperate reasonably with such Series A Unitholder to provide
information requested by potential purchasers to potential purchasers, to make the Partnership’s management reasonably available by telephone and to confirm that the Partnership has made all requisite filings required under the Exchange Act;
provided that, prior to providing any information requested or conducting any telephonic discussions, such potential purchasers enter into a customary non-disclosure agreement in respect of such information provided by the Partnership in a form
reasonably acceptable to the Partnership. 
 (x) Tax Estimates. Upon receipt of a written request from any Series A
Unitholder stating the number of Series A Preferred Units owned by such holder (which requests shall be made no more than two (2) times per calendar year and the first such request per calendar year shall be at the Partnership’s expense,
and the second at the expense of such requesting holder), the Partnership shall, within ten (10) days, provide such Series A Unitholder with a good faith estimate (and reasonable supporting calculations) of whether there is sufficient
Unrealized Gain attributable to the Partnership property such that, if such Series A Unitholder converted its Series A Preferred Units pursuant to Section 5.12(b)(viii)(A) or (B) and such Unrealized Gain was allocated to such
holder pursuant to Section 5.5(d)(iii), such holder’s Capital Account in respect of its converted Series A Preferred Units would be equal to the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Conversion
Unit received in connection with such conversion of a Series A Preferred Unit). 
 (xi) Fully Paid and Nonassessable. Any
Conversion Unit(s) delivered pursuant to this Section 5.12 shall be validly issued, fully paid and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware
Act), free and clear of any liens, claims, rights or encumbrances other than those arising under the Delaware Act or this Agreement or created by the holders thereof. 
 (xii) Listing of Common Units. The Partnership will procure, at its sole expense, the listing of the Conversion Units issuable upon conversion of the Series A Preferred Units, subject to issuance
or notice of issuance on any National Securities Exchange on which the Common Units are listed or admitted to trading.

 (D) Fourth, to the General Partner and all Unitholders, Pro Rata, until the Capital Account in respect
of each Common Unit then Outstanding is equal to the sum of (1) its Unrecovered Initial Unit Price, (2) the Unpaid MQD, (3) any then-existing Cumulative Common Unit Arrearage, and (4) the excess of (aa) the First Target
Distribution less the Minimum Quarterly Distribution for each Quarter of the Partnership’s existence over (bb) the cumulative per Unit amount of any distributions of Available Cash that is deemed to be Operating Surplus made pursuant to
Section 6.4(b)(iv) and Section 6.4(c)(ii) (the sum of (1), (2), (3) and (4) is hereinafter defined as the “First Liquidation Target Amount”); 

  
 69 

 (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 subclauses (x) and (y) of
this clause (E), until the Capital Account in respect of each Common Unit then Outstanding is equal to the sum of (1) the First Liquidation Target Amount, and (2) the excess of (aa) the Second Target Distribution less the First Target

rata part of each item of income, gain, loss, and deduction taken into account in computing Net Termination Loss) shall be allocated: 
 (A) First, if Subordinated Units remain Outstanding, (x) to the General Partner in accordance with its Percentage Interest and (y) to all Unitholders holding Subordinated Units, Pro Rata,

Unitholders holding Common Units, Pro Rata, a percentage equal to 100% less the General Partner’s Percentage Interest, until the Capital Account in respect of each Common Unit then Outstanding has been reduced to zero; 

  
 70 

 (C) Third, to the General Partner and the Unitholders, Pro Rata;
provided that Net Termination Loss shall not be allocated pursuant to this Section 6.1(c)(ii)(C) to the extent such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account (or increase any existing
deficit in its Adjusted Capital Account); and 
 (D) Fourth, the balance, if any, 100% to the General
Partner. 
 (iii) Any Net Termination Loss deemed recognized pursuant to Section 5.5(d) prior to the Liquidation
Date shall be allocated: 
 (A) First, to the General Partner and the Unitholders, Pro Rata;
provided that Net Termination Loss shall not be allocated pursuant to this Section 6.1(c)(iii)(A) to the extent such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of
such taxable period (or increase any existing deficit in its Adjusted Capital Account); and 
 (B) The balance,
if any, to the General Partner. 
 (iv) If a Net Termination Loss has been allocated pursuant to
Section 6.1(c)(iii), subsequent Net Termination Gain deemed recognized pursuant to Section 5.5(d) prior to the Liquidation Date shall be allocated: 

(A) First, to the General Partner until the aggregate Net Termination Gain allocated to the General Partner
pursuant to this Section 6.1(c)(iv)(A) is equal to the aggregate Net Termination Loss previously allocated pursuant to Section 6.1(c)(iii)(B); 

(B) Second, to the General Partner and the Unitholders, Pro Rata, until the aggregate Net Termination Gain
allocated pursuant to this Section 6.1(c)(iv)(B) is equal to the aggregate Net Termination Loss previously allocated pursuant to Section 6.1(c)(iii)(A); and 

(C) The balance, if any, pursuant to the provisions of Section 6.1(c)(i). 

(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. 

  
 71 

 (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), other than Section 6.1(d)(i) and other than an allocation pursuant to
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 (other than a Series A Preferred Unit) exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Unit (other than a Series A Preferred 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 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), the remaining items of Partnership 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 

  
 72 

 
Distributions made to the holders of Incentive Distribution Rights from the IPO Closing Date to a date 45 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, 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 Allocations. 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, that an allocation pursuant to this
Section 6.1(d)(v) shall be made only if and to the extent that such Partner would have a deficit balance in its Capital Account as adjusted after all other allocations provided for in this Section 6.1 have been tentatively
made as if Section 6.1(d)(iv) and this Section 6.1(d)(v) were not in this Agreement. 
 (vi)
Nonrecourse Deductions. Nonrecourse Deductions for any taxable period shall be allocated to the Partners Pro Rata. If the General Partner determines that the Partnership’s Nonrecourse Deductions should be allocated in a different ratio
to satisfy the safe harbor requirements of the Treasury Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the other Partners, to revise the prescribed ratio to the numerically closest
ratio that does satisfy such requirements. 
 (vii) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for
any taxable period shall be allocated 100% to the Partner that bears the Economic Risk of Loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulation
Section 1.704-2(i). If more than one Partner bears the Economic Risk of Loss with respect to a Partner Nonrecourse Debt, such 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. 

  
 73 

 (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 (A) the number of Final Subordinated Units held by such Partner and (B) 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 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 (a) the Aggregate Quantity of IDR Reset Common Units and
(B) the Per Unit Capital Amount for an IPO Common Unit. 

  
 74 

 (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
Account for an IPO 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 (i) adopt such conventions as it deems appropriate in determining the amount of depreciation, amortization and cost recovery deductions;
(ii) make special allocations of income, gain, loss, deduction, Unrealized Gain or Unrealized Loss; and (iii) 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 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 

  
 75 

 
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)), the General Partner shall allocate such Additional Book Basis Derivative Items (1) to 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) to 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) or an allocation of Net Termination Gain or Net Termination Loss pursuant to Section 6.1(c)) 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 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. 

  
 76 

 (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. 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 (d)(xii)(A)-(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. 

(xiv) Redemption of Series A Preferred Units. Notwithstanding any other provision of this Section 6.1 (other than the
Regulatory Allocations), with respect to any taxable period during which Series A Preferred Units are redeemed pursuant to the terms of Section 5.12(b)(viii)(F), each Partner holding redeemed Series A Preferred Units shall, to the extent
necessary after the allocation of Unrealized Gain and Unrealized Loss pursuant to Section 5.5(d)(ii), be allocated items of income, gain, loss and deduction in a manner that results in the Capital Account balance of each such Partner
attributable to its redeemed Series A Preferred Units immediately prior to such redemption (and after taking into account any applicable Regulatory Allocations) to equal (i) the amount of cash paid to such Partner in redemption of such Series A
Preferred Units, and (ii) the product of the number of Common Units received in the redemption and the Per Unit Capital Amount for a then Outstanding Common Unit. 

  
 77 

 Section 6.2 Allocations for Tax Purposes. 

(a) Except as otherwise provided herein, for federal income tax purposes, each item of income, gain, loss and deduction shall be
allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 6.1. 
 (b) In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, depreciation, amortization and cost recovery deductions shall
be allocated for federal income tax purposes among the Partners in the manner provided under Section 704(c) of the Code, and the Treasury Regulations promulgated under Section 704(b) and 704(c) of the Code, as determined appropriate by the
General Partner (taking into account the General Partner’s discretion under Section 6.1(d)(x)(D)); provided, 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) In accordance with Treasury Regulation Sections 1.704-1(b)(2)(iv)(s) and 1.704-1(b)(4)(x), if Capital Account balances are
reallocated among Partners in accordance with Section 5.5(d)(iii), beginning with the year of reallocation and continuing until the allocations required are fully taken into account, the Partnership will make corrective allocations to take into
account the Capital Account reallocation. 
 (f) 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. 

  
 78 

 (g) Each item of Partnership income, gain, loss and deduction, for federal income tax
purposes, shall be determined for each taxable period and prorated on a monthly basis and shall be allocated to the Partners as of the opening of the National Securities Exchange on which the Partnership Interests are listed or admitted to trading
on the first Business Day of each month; provided, however, such items for the period beginning on the IPO Closing Date and ending on the last day of the month in which the 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; and 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.

 (h) 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 in any case in which the nominee 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) Except as described in Section 6.3(b) or Section 6.3(c), within
45 days following the end of each Quarter, an amount equal to 100% of Available Cash with respect to such Quarter shall be distributed in accordance with this Article VI by the Partnership to the Partners as of the Record Date selected by the
General Partner. All amounts of Available Cash distributed by the Partnership on any date following the IPO Closing Date from any source shall be deemed to be Operating Surplus until the sum of all amounts of Available Cash distributed by the
Partnership to the Partners following the IPO Closing Date pursuant to Section 6.4(b) equals the Operating Surplus from the IPO 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.” Notwithstanding any other provision of this Agreement, all distributions required
to be made under this Agreement or otherwise made by the Partnership shall be made subject to Sections 17-607 and 17-804 of the Delaware Act. Notwithstanding any provision to the contrary contained in this Agreement, the Partnership shall not be
required to make a distribution to any Partner on account of its interest in the Partnership if such distribution would violate the Delaware Act or any other applicable law. 

  
 79 

 (b) Notwithstanding 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, other than from Working Capital Borrowings, 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 Available Cash to such Partners. 

(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) On the IPO Closing Date. Subject to Section 17-607 of the Delaware Act, on the IPO Closing Date and immediately prior to
the commencement of the Subordination Period, the IPO Proceeds and New Credit Facility Proceeds shall be distributed to (x) the General Partner in accordance with its Percentage Interest and (y) AIM Midstream and the LTIP Partners, as
Unitholders, Pro Rata, a percentage equal to 100% less the General Partner’s Percentage Interest. The distribution made to AIM Midstream and the General Partner will be a reimbursement for certain capital expenditures incurred with respect to
Partnership assets. 
 (b) During Subordination Period. Available Cash with respect to any Quarter within the

Arrearage existing with respect to such Common Unit; 
 (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; 

  
 80 

 (iv) Fourth, to the General Partner and all Unitholders, in accordance with their
respective Percentage Interests, 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;

 (c) After 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, subject to Section 17-607 of the Delaware Act, be distributed as follows, except as otherwise required by
Section 5.6 in respect of additional Partnership Interests or other securities issued pursuant thereto:

Section 6.5 Distributions of Available Cash from Capital Surplus. 

Available Cash with respect to any Quarter ending on or after the IPO Closing Date that is deemed to be Capital Surplus pursuant to the
provisions of Section 6.3(a) shall, subject to Section 17-607 of the Delaware Act and after giving effect to the distributions pursuant to Section 6.4(a), be distributed, unless the provisions of Section 6.3

 Section 6.6 Adjustment of Minimum Quarterly
Distribution and Target Distribution Levels. 
 (a) The 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 the event of a distribution of
Available Cash that is deemed to be from Capital Surplus, the then applicable Target Distributions shall be reduced in the same proportion 

  
 82 

 
that the distribution had to the fair market value of the Common Units immediately prior to the announcement of the distribution. If the Common Units are publicly traded on a National Securities
Exchange, the fair market value will be the Current Market Price before the ex-dividend date. If the Common Units are not publicly traded, the fair market value will be determined by the Board of Directors. 

(b) The Target Distributions 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 holding a Subordinated Unit shall possess
all of the rights and obligations of a Unitholder holding Common Units hereunder with respect to such Common Units issued upon conversion of such 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 Common Units issued upon conversion of such Subordinated Units shall remain subject to the provisions of
Section 5.5(c)(ii), Section 6.1(d)(x)(A), Section 6.7(b) and Section 6.7(c). 

(b) A Unitholder shall not be permitted to transfer a Subordinated Unit or a Common Unit that has been issued upon conversion of 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) A Unitholder holding a Common Unit that has resulted from the conversion of a Subordinated Unit pursuant to Section 5.7 shall not be issued a Common Unit Certificate pursuant to
Section 4.1, if the Common Units are evidenced 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 U.S. federal income tax characteristics, in all material respects, to the intrinsic economic and U.S. federal income tax characteristics of an
IPO 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 Section 5.5(c)(ii), Section 6.1(d)(x), Section 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. 

  
 83 

 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 (i) shall (A) possess the rights and obligations provided in this Agreement with respect to a Limited Partner pursuant to Article III and Article VII and (B) have a Capital Account as a Partner pursuant to
Section 5.5 and all other provisions related thereto and (ii) shall not (A) be entitled to vote on any matters requiring the approval or vote of the holders of Outstanding Units, except as provided by law, (B) be entitled
to any distributions other than as provided in Section 6.4(b)(v), Section 6.4(b)(vi) and Section 6.4(b)(vii), Section 6.4(c)(iii), Section 6.4(c)(iv) and Section 6.4(c)(v), and
Section 12.4 or (C) be allocated items of income, gain, loss or deduction other than as specified in this Article VI. 
 (b) The Unitholder holding Common Units that have resulted from the conversion of Incentive Distribution Rights 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, 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 U.S. federal income tax characteristics, in all material respects, to the intrinsic economic and U.S. federal income tax characteristics
of an IPO Common Unit. In connection with the condition imposed by this Section 6.8(b), 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 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, in its sole discretion, reduce 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 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 Target Distributions shall be the product obtained by multiplying (a) the amounts therefor that are set 

  
 84 

 
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. 
 Section 6.10 Special Provisions Relating to
Series A Preferred Unitholders. 
 (a) Subject to transfer restrictions in Section 4.8 of this Agreement, a
Unitholder holding a Conversion Unit shall provide notice to the Partnership of any Transfer of the Conversion Unit by the earlier of (i) thirty (30) days following such Transfer and (ii) the last Business Day of the calendar year
during which such transfer occurred, unless (x) the transfer is to an Affiliate of such Unitholder or (y) by virtue of the application of Section 5.5(d)(iii), the Partnership has previously determined, based on the advice of
counsel, that the Conversion Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics of an IPO Common Unit. In connection with the condition imposed by this Section 6.10, the Partnership
shall take whatever steps are required to provide economic uniformity to the Conversion Unit in preparation for a transfer of such Unit; provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders
holding Common Units (for this purpose the allocations of income, gain, loss and deductions, and the making of any guaranteed payments or any reallocation of Capital Account balances among the Partners in accordance with
Section 5.5(d)(iii) hereof and Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(4) with respect to Series A Preferred Units or Conversion Units will be deemed not to have a material adverse effect on the Unitholders holding Common
Units). 
 (b) Notwithstanding anything to the contrary set forth in this Agreement, the holders of the Series A Preferred Units
(a) shall (i) possess the rights and obligations provided in this Agreement with respect to a Limited Partner pursuant to Article III and Article VII and (ii) have a Capital Account as a Partner pursuant to
Section 5.5 and all other provisions related thereto and (b) shall not (i) be entitled to vote on any matters requiring the approval or vote of the holders of Outstanding Units, except as provided in Section 5.12 or
(ii) be entitled to any distributions other than as provided in Section 5.12 and Article VI. 

ARTICLE VII 
 MANAGEMENT AND OPERATION OF BUSINESS 
 Section 7.1 Management.

 (a) The General Partner shall conduct, direct and manage all activities of the Partnership. Except as otherwise expressly
provided in this Agreement, but without limitation on the ability of the General Partner to delegate its rights and powers to other Persons, all management powers over the business and affairs of the Partnership shall be exclusively vested in the
General Partner, and no Limited Partner shall have any management power over the business and affairs of the Partnership. In addition to the powers now or hereafter granted a general partner of a limited partnership under applicable law or that are
granted to the General 

  
 85 

 
Partner under any other provision of this Agreement, the General Partner, subject to Section 7.3, shall have full power and authority to do all things and on such terms as it

prior approval that may be required by Section 7.3 and Article XIV); 
 (iv) the use of the assets of the
Partnership (including cash on hand) for any purpose consistent with the terms of this Agreement, including the financing of the conduct of the operations of the Partnership Group; subject to Section 7.6(a), the lending of funds to other
Persons (including other Group Members); the repayment or guarantee of obligations of any Group Member; and the making of capital contributions to any Group Member; 
 (v) the negotiation, execution and performance of any contracts, conveyances or other instruments (including instruments that limit the liability of the Partnership under contractual arrangements to all
or particular assets of the Partnership, with the other party to the contract to have no recourse against the General Partner or its assets other than its interest in the Partnership, even if the same results in the terms of the transaction being
less favorable to the Partnership than would otherwise be the case); 
 (vi) the distribution of Partnership cash; 

(vii) the selection, employment, retention and dismissal of employees (including employees having titles such as “president,”
“vice president,” “secretary” and “treasurer”) and agents, outside attorneys, accountants, consultants and contractors of the General Partner or the Partnership Group and the determination of their compensation and
other terms of employment or hiring; 
 (viii) the maintenance of insurance for the benefit of the Partnership Group, the

acquire an interest in Partnership Interests or in the Partnership or 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
Contribution Agreement and the consummation of the transactions contemplated hereby and thereby; (ii) agrees that the General Partner (on its own or on behalf of the Partnership) is authorized to execute, deliver and perform the agreements

Group Member or any Affiliate 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

at law, in equity or otherwise. 

  
 87 

 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 3.4(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. 

(a) 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 without the approval 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. 
 (b) Notwithstanding any
other provisions of this Agreement, the General Partner shall not, without the prior written consent of the Series A Preferred Unit Partner, for so long as the Series A Preferred Unit Partner holds at least 50% of the Units held by the Series A
Preferred Unit Partner immediately following the closing of transactions contemplated by the Contribution Agreement (with respect to Series A Preferred Units, calculated on an as converted basis and including any Common Units into which any Series A
Preferred Units have been converted pursuant to Section 5.12(b)(viii) hereof): 
 (i) cause or permit the
Partnership or any Group Member to invest in, or dispose of, the equity securities or debt securities of any Person or otherwise acquire or dispose of any interest in any Person, to acquire or dispose of interest in any joint venture or partnership
or any similar arrangement with any Person, or to acquire or dispose of assets of any Person, or to make any capital expenditure (other than Maintenance Capital Expenditures), or to make any loan or advance to any Person if the total consideration
(including cash, equity issued and debt assumed) paid or payable, or received or receivable, by the Partnership or any Group Member exceeds $15,000,000 in any one or series of related transactions or in the aggregate within the Partnership Group
exceeds $50,000,000 in any twelve-month period; 

  
 88 

 (ii) cause or permit the Partnership or any Group Member to (i) incur, create or
guarantee any Indebtedness which exceeds (x) $75,000,000 in any one or series of related transactions to the extent the proceeds of such financing are used to refinance existing Indebtedness, or (y) $25,000,000 in any twelve-month period
to the extent such Indebtedness increases the aggregate Indebtedness of the Partnership Group, taken as a whole, or (ii) incur, create or guarantee any Indebtedness with a yield to maturity exceeding ten percent (10)%; 

(iii) authorize or permit the purchase, redemption or other acquisition of Partnership Interests (or any options, rights, warrants or
appreciation rights relating to the Partnership Interests) by any Group Member; 
 (iv) select or dismiss, or enter into any
employment agreement or amendment of any employment agreement of, the Chief Executive Officer and the Chief Financial Officer of the Partnership or the Operating Company; 
 (v) enter into any agreement or effect any transaction between the Partnership or any Group Member, on the one hand, and any Affiliate of the Partnership or the General Partner, on the other hand, other
than any transaction in the ordinary course of business and determined by the Board of Directors to be on an arm’s length basis; or 
 (vi) cause or permit the Partnership or any Group Member to enter into any agreement or make any commitment to do any of the foregoing. 

Section 7.4 Reimbursement of the General Partner. 
 (a) Except as provided in this Section 7.4 and elsewhere in this Agreement, the General Partner shall not be compensated for its services as a general partner or managing member of any Group
Member. 
 (b) 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, employment benefits and other amounts paid to any Person, including
Affiliates of the General Partner to perform services for 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 in connection with operating the Partnership Group’s business (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the
General Partner or 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 Affiliates of the General Partner in a manner consistent with 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) and past business practices shall be deemed to be fair and reasonable to the Partnership. 

  
 89 

 (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 benefit plans, programs and practices (including the Long Term Incentive Plan and other plans, programs and practices involving the issuance of Partnership
Interests or options to purchase or rights, warrants or appreciation rights or phantom or tracking interests or other economic interests in the Partnership or relating to Partnership Interests), or cause the Partnership to issue Partnership
Interests or other securities in connection with, or pursuant to, any benefit plan, program or practice maintained or sponsored by the General Partner or any of its Affiliates in each case for the benefit of employees, officers 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 or other securities that the General Partner or such Affiliates are obligated to provide to any employees, officers and directors pursuant to any such benefit plans, programs or 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 or other securities purchased by the General Partner or such Affiliates, from the Partnership or
otherwise, 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 benefit plans, programs or 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. 

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 Registration Statement, (B) the acquiring, owning or disposing of debt securities or equity interests in any Group Member or (C) the guarantee of, and mortgage, pledge, or encumbrance of
any or all of its assets in connection with, any indebtedness of any Affiliate of the General Partner. 
 (b) 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

  
 90 

 
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 fiduciary 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, 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
fiduciary or other 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 such Unrestricted Person does not engage in such business or activity as a result of or 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
IPO Closing Date and, except as otherwise provided in this Agreement, shall be entitled to exercise, at their option, all rights relating to all Units 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. 
 (e)
Notwithstanding anything to the contrary in this Agreement, to the extent that any provision of this Agreement purports or is interpreted to have the effect of restricting or eliminating the fiduciary duties that might otherwise, as a result of
Delaware or other applicable law, be owed by the General Partner to the Partnership and its Limited Partners, or to constitute a waiver or consent by the Limited Partners to any such restriction or elimination, such provisions shall be deemed to
have been approved by the Partners. 

  
 91 

 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, but shall be under no obligation to, lend
to any Group Member, and any Group Member may, but shall be under no obligation to, 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 hereunder or otherwise existing at law, in equity or otherwise, 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, 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; 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 fraud, willful misconduct or, in the case of a criminal 

  
 92 

 
matter, acted with knowledge that the Indemnitee’s conduct was unlawful. 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 appearing at, participating in or 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, 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, the Indemnitees and such other Persons as the General Partner shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with the
Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

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

(f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification provisions set
forth in this Agreement. 
 (g) An Indemnitee shall not be denied indemnification in whole or in part under this
Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. 

  
 93 

 (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 Partners or any other Persons who have acquired
interests in the Partnership Interests, 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 fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was criminal. 

(b) Subject to its obligations and duties as General Partner set forth in Section 7.1(a), 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 for its good faith reliance on the provisions of this Agreement. 
 (d) Any amendment,
modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the liability of the Indemnitees under this Section 7.8 as in effect immediately
prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

  
 94 

 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 (in its individual capacity or its capacity as general partner, limited partner or holder of Incentive Distribution Rights) 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 hereunder stated or implied by law or equity or otherwise, 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. If Special Approval is sought, then it shall be presumed that, in making
its decision, the Conflicts Committee acted in good faith, and if neither Special Approval nor Unitholder approval is sought and 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, then it shall be presumed that, in making its decision, the Board of Directors acted in good faith, and 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 such approval, the Person bringing or prosecuting such proceeding shall have the burden of overcoming such presumption. 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 Registration Statement and any actions of the General Partner taken in connection therewith are hereby approved
by all Partners and shall not constitute a breach of this Agreement or of any duty hereunder or existing at law, in equity or otherwise. 
 (b) Whenever the General Partner, the Board of Directors or any committee of thereof (including the Conflicts Committee), makes a determination or takes or declines to take any other action, or any of its
Affiliates causes the General Partner to do so, in the General Partner’s 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, 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. In order for a determination or other action to be in “good faith” for purposes of this Agreement, the Person or Persons making such
determination or taking or declining to take such other action must subjectively believe that the determination or other action is in, or not opposed to, the best interests of the Partnership. 

  
 95 

 (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
(including any fiduciary duty) or obligation whatsoever to the Partnership, any Limited Partner or any other Person bound by this Agreement, 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. By
way of illustration and not of limitation, whenever the phrases, “at the option of the General Partner,” “in its sole discretion” or some variation of those phrases, are 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, or otherwise acts in its capacity
as a limited partner or holder of Partnership Interests other than the General Partner Interest, it shall be acting in its individual capacity. 
 (d) 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 in its sole discretion. 

(e) Except as expressly set forth in this Agreement, 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. 

(f) The Limited Partners hereby authorize the General Partner, on behalf of the Partnership as a partner or member of a Group Member, to
approve of 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. 

  
 96 

 Section 7.10 Other Matters Concerning the General Partner. 

(a) The General Partner may rely upon, 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 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 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 advice or 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. 
 Subject to Section 5.12(b)(v), the General Partner may cause the Partnership to purchase
or otherwise acquire Partnership Interests; provided that, except as permitted pursuant to Section 4.10 or with approval of the Conflicts Committee, 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 Article IV and Article X. 

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

(a) If (i) the General Partner or any Affiliate of the General Partner (including for purposes of this Section 7.12, any
Person that is an Affiliate of the General Partner at the date hereof notwithstanding that it may later cease to be an Affiliate of the General Partner, but excluding any individual who is an Affiliate of the General Partner based on such
individual’s status as an officer, director or employee of the General Partner or an Affiliate of the General Partner) holds Partnership Interests that it desires to sell and (ii) Rule 144 of the Securities Act (or any successor rule or
regulation to Rule 144) or another exemption from registration is not available to enable such holder of Partnership Interests (the “Holder”) to dispose of the number of Partnership Interests it desires to sell at the time it
desires to do so without registration under the Securities Act, then at the option and upon the request of the Holder, the Partnership shall file with the Commission as promptly as practicable after receiving such request, and use all commercially
reasonable efforts to cause to become effective and remain effective for a period of not less than six months following its effective date or such shorter period as shall terminate when all Partnership Interests covered by such registration
statement have been sold, a

registration statement under the Securities Act registering the offering and sale of the number of Partnership Interests specified by the Holder; provided, however, that the
Partnership shall not be required to effect more than three registrations pursuant to this Section 7.12(a); and provided further, however, that if the General Partner determines that a postponement of the requested
registration would be in the best interests of the Partnership and its Partners due to a pending transaction, investigation or other event, the filing of such registration statement or the effectiveness thereof may be deferred for up to six months,
but not thereafter. In connection with any registration pursuant to the immediately preceding sentence, the Partnership shall (i) promptly prepare and file (A) such documents as may be necessary to register or qualify the securities
subject to such registration under the securities laws of such states as the Holder shall reasonably request; provided, however, that no such qualification shall be required in any jurisdiction where, as a result thereof, the
Partnership would become subject to general service of process or to taxation or qualification to do business as a foreign corporation or partnership doing business in such jurisdiction solely as a result of such registration, and (B) such
documents as may be necessary to apply for listing or to list the Partnership Interests subject to such registration on such National Securities Exchange as the Holder shall reasonably request, and (ii) do any and all other acts and things that
may be necessary or appropriate to enable the Holder to consummate a public sale of such Partnership Interests in such states. Except as set forth in Section 7.12(c), all costs and expenses of any such registration and offering (other
than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder. 
 (b)
If the Partnership shall at any time propose to file a registration statement under the Securities Act for an offering of Partnership Interests for cash (other than an offering relating solely to a benefit plan), the Partnership shall use all
commercially reasonable efforts to include such number or amount of Partnership Interests held by any Holder in such registration statement as the Holder shall request; provided, that the Partnership is not required to make any effort or take
any action to so include the Partnership Interests of the Holder once the registration statement becomes or is declared effective by the Commission, including any registration statement providing for the offering from time to time of Partnership
Interests pursuant to Rule 415 of the Securities Act. If the proposed offering pursuant to this Section 7.12(b) shall be an underwritten offering, then, in the event that the managing underwriter or managing underwriters of such
offering advise the Partnership and the Holder that in their opinion the inclusion of all or some of the Holder’s Partnership Interests would adversely and materially affect the timing or success of the offering, the Partnership shall include
in such offering only that number or amount, if any, of Partnership Interests held by the Holder that, in the opinion of the managing underwriter or managing underwriters, will not so adversely and materially affect the offering. Except as set forth
in Section 7.12(c), all costs and expenses of any such registration and offering (other than the underwriting discounts and commissions) shall be paid by the Partnership, without reimbursement by the Holder. 

(c) If underwriters are engaged in connection with any registration referred to in this Section 7.12, the Partnership shall
provide indemnification, representations, covenants, opinions and other assurance to the underwriters in form and substance reasonably satisfactory to such underwriters. Further, 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 the Holder, its officers, directors and each Person who controls the Holder (within the

  
 98 

 
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(c) 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 under which any
Partnership Interests were registered under the Securities Act or any state securities or Blue Sky laws, in any preliminary prospectus (if used prior to the effective date of such registration statement), or in any summary or final prospectus or
issuer free writing prospectus or in any amendment or supplement thereto (if used during the period the Partnership is required to keep the registration statement current), 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 made 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, such preliminary, summary or final prospectus or any free
writing prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Indemnified Person specifically for use in the preparation thereof. 

(d) The provisions of Section 7.12(a) and Section 7.12(b) shall continue to be applicable with respect to the
General Partner (and any of the General Partner’s Affiliates) after it ceases to be a general partner of the Partnership, during a period of two years subsequent to the effective date of such cessation and for so long thereafter as is required
for the Holder to sell all of the Partnership Interests with respect to which it has requested during such two-year period inclusion in a registration statement otherwise filed or that a registration statement be filed; provided,
however, that the Partnership shall not be required to file successive registration statements covering the same Partnership Interests for which registration was demanded during such two-year period. The provisions of
Section 7.12(c) shall continue in effect thereafter. 
 (e) The rights to cause the Partnership to register
Partnership Interests pursuant to this Section 7.12 may be assigned (but only with all related obligations) by a Holder to a transferee or assignee of such Partnership Interests, provided (i) the Partnership is, within a reasonable
time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the Partnership Interests with respect to which such registration rights are being assigned; and (ii) such transferee or assignee
agrees in writing to be bound by and subject to the terms set forth in this Section 7.12. 
 (f) Any request to
register Partnership Interests pursuant to this Section 7.12 shall (i) specify the Partnership Interests intended to be offered and sold by the Person making the request, (ii) express such Person’s present intent to offer
such Partnership Interests for distribution, (iii) describe the nature or method of the proposed offer and sale of Partnership Interests, and (iv) contain the undertaking of such Person to provide all such information and materials and
take all action as may be required in order to permit the Partnership to comply with all applicable requirements in connection with the registration of such Partnership Interests.

 (g) The Partnership may enter into separate registration rights agreements with the General
Partner or any of its Affiliates. 
 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.

made a report available to each Record Holder as required by this Section 8.3 if it has either (i) filed such report with the Commission via its Electronic Data Gathering, Analysis and Retrieval system, or any successor system, and
such report is publicly available on such system or (ii) made such report available on any publicly available website maintained by the Partnership.

 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 years 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

(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.

from doing any or all things reasonably required by the General Partner to conduct such proceedings. 
 Section 9.4

(b) 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 or any other federal, state or local law including pursuant to Sections 1441, 1442, 1445 and 1446 of the Code. 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 in the amount of such withholding from such Partner.

in accordance with the provisions of Article IV or Article V. A Person may become a Record Holder of a Limited Partner Interest without the consent or approval of any of the Partners. A Person may not become a Limited Partner without

from time to time as necessary to reflect accurately the information therein (or shall cause the Transfer Agent to do so, as applicable). A Limited Partner Interest may be represented by a Certificate, as provided in Section 4.1.

 (d) 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).

effective immediately prior to the withdrawal or removal of the predecessor or transferring General Partner, pursuant to Section 11.1 or Section 11.2 or the transfer of the General Partner Interest (represented by Notional
General Partner Units) 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

without dissolution.

 (v) A final and non-appealable order of relief under Chapter 7 of the United States Bankruptcy Code is entered by a court with appropriate jurisdiction pursuant to a voluntary or involuntary petition by

 If an Event of Withdrawal specified in Section 11.1(a)(iv), Section 11.1(a)(v), Section 11.1(a)(vi)(A), Section 11.1(a)(vi)(B),
Section 11.1(a)(vi)(C) or Section 11.1(a)(vi)(E) occurs, the withdrawing General Partner shall give notice to the Limited Partners within 30 days after such occurrence. The Partners hereby agree that only the Events of
Withdrawal described in this Section 11.1 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 before 12:00 midnight, Central Time, on June 30, 2021, 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 held 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 any Group Member or cause any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not already so treated or taxed);
(ii) at any time after 12:00 midnight, Central Time, on June 30, 2021, the General Partner voluntarily withdraws by giving at least 90 days’ advance notice to the Unitholders, such withdrawal to take effect on the date specified in

time such notice is given one Person and its Affiliates (other than the General Partner and its Affiliates) own beneficially or of 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, 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 pursuant to
Section 11.1(a)(i), a successor is not selected 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. 

  
 105

 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 separate class and a majority of the Outstanding Subordinated Units (if any Subordinated Units are then Outstanding)
voting as a separate 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 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. 

  
 106

 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 value of the Units, including 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 (and
its Affiliates, if applicable) shall become a Limited Partner and the 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 General Partner as to all
debts and liabilities of the Partnership arising on or after the date on which the Departing General Partner becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest to Common Units will be characterized as if
the Departing General Partner (and its Affiliates, if applicable) contributed the 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 respect of its General Partner
Interest. 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. 

  
 107

 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 5.5(c)(ii), Section 6.1(d)(x) and 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 (represented by Notional General Partner Units) 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 successor General Partner is elected pursuant to Section 11.1, Section 11.2 or Section 12.2, the
Partnership shall not be dissolved and such successor General Partner is hereby authorized to, and shall, continue the business of the Partnership. Subject to Section 12.2, the Partnership shall dissolve, and its affairs shall be wound
up, upon: 
 (a) an Event of Withdrawal of the General Partner as provided in Section 11.1(a), unless a successor is
admitted to the Partnership pursuant to this Agreement; 
 (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 

  
 108

 (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 an Event of Withdrawal caused by (a) the withdrawal or removal of the General Partner as
provided in Section 11.1(a)(i) or Section 11.1(a)(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 within 90
days thereafter, or (b) an event constituting an Event of Withdrawal as defined in Section 11.1(a)(iv), Section 11.1(a)(v) or Section 11.1(a)(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, effective as of the date of the Event of Withdrawal, 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, 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 under the Delaware Act of any Limited Partner and (y) neither the Partnership nor any Group Member would be
treated as an association taxable as a corporation or otherwise be taxable as an entity for U.S. 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, 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

  
 109

 
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 reserve of cash or other assets to provide for its payment. When paid, any unused portion of the reserve shall be applied as additional
liquidation proceeds. 
 (c) All property and all cash in excess of that required to discharge liabilities as provided in
Section 12.4(b) and that required to satisfy liquidation preferences of the Series A Preferred Units provided for under Section 5.12(b)(iv) 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). 

  
 110

 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 period of the Partnership during which such liquidation occurs, or, if later, within 90 days after the date of such liquidation. 
 Section 12.9 Series A Liquidation Value. 
 Notwithstanding anything to
the contrary set forth in this Agreement, the holders of the Series A Preferred Units shall have the rights, preferences and privileges set forth in Section 5.12(b)(iv) upon liquidation of the Partnership pursuant to this Article
XII. 
 ARTICLE XIII 
 AMENDMENT OF PARTNERSHIP AGREEMENT; 
 MEETINGS; RECORD DATE 

Section 13.1 Amendments to be Adopted Solely by the General Partner. 

Except as set forth in Section 5.12(b)(v), each Partner agrees that the General Partner, without the approval of any Partner,
may amend any provision of this Agreement and execute, swear to, acknowledge, deliver, file and record whatever documents may be required in connection therewith, to reflect: 

  
 111

 (a) a change in the name of the Partnership, the location of the principal place of business
of the Partnership, the registered agent of the Partnership or the registered office of the Partnership; 
 (b) the admission,
substitution, withdrawal or removal of Partners in accordance with this Agreement; 
 (c) a change that the General Partner

Group Members will not be treated as associations taxable as corporations or otherwise taxed as entities for federal income tax purposes; 
 (d) a change that the General Partner determines, (i) does not adversely affect in any material respect the Limited Partners considered as a whole or any particular class of Partnership Interests as
compared to other classes of Partnership Interests, (ii) to be necessary or appropriate to (A) satisfy any requirements, conditions or guidelines contained in any opinion, directive, order, ruling or regulation of any federal or state
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 Registration Statement or the intent of the provisions of this
Agreement or is otherwise contemplated by this Agreement; 
 (e) a change in the fiscal year or taxable period of the Partnership
and any other changes that the General Partner determines to be necessary or appropriate as a result of a change in the fiscal year or taxable period of the Partnership including, if the General Partner shall so determine, a change in the definition

the Investment Advisers Act of 1940, as amended, or “plan asset” regulations adopted under the Employee Retirement Income Security Act of 1974, as amended, regardless of whether such are substantially similar to plan asset regulations
currently applied or proposed by the United States Department of Labor; 
 (g) an amendment that the General Partner determines
to be necessary or appropriate in connection with the creation, authorization or issuance of any class or series of Partnership Interests and options, rights, warrants, appreciation rights, tracking and phantom interests or other economic interests
in the Partnership relating to Partnership Interests pursuant to Section 5.6, including any amendment that the General Partner determines is necessary or appropriate in connection with (i) the adjustments of the Target Distributions
pursuant to the 

  
 112

 
provisions of Section 5.11, (ii) the implementation of the provisions of Section 5.11 or (iii) any modifications to the Incentive Distribution Rights made in
connection with the issuance of Partnership Interests pursuant to Section 5.6, provided that, with respect to this clause (iii), the modifications to the Incentive Distribution Rights and the related issuance of Partnership
Interests have received Special Approval;

permitted by the terms of Section 2.4 or Section 7.1(a); 
 (k) a merger, conveyance or conversion
pursuant to Section 14.3(d); or 
 (l) any other amendments substantially similar to the foregoing. 

Section 13.2 Amendment Procedures. 
 Except as provided in Section 13.1 and Section 13.3, all amendments to this Agreement shall be made in accordance with the requirements contained in this Section 13.2.
Amendments to this Agreement may be proposed only by the General Partner; provided, however, that, to the full 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 (including any fiduciary 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
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. A proposed amendment shall be effective upon its approval by the General Partner and, except as otherwise provided by Section 13.1 and Section 13.3, the holders of a Unit Majority, unless
a greater or different percentage 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 such proposed amendments. The General Partner shall be deemed to have notified all Record Holders as required by this Section 13.2 if it has either (i) filed
such amendment with the Commission via its Electronic Data Gathering, Analysis and Retrieval system, or any successor system, and such amendment is publicly available on such system or (ii) made such amendment available on any publicly
available website maintained by the Partnership. 

  
 113

 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 (including Units deemed owned by the General Partner) or requires a vote or approval of Partners (or a subset of the Partners) holding a specified Percentage Interest required to take any action shall be
amended, altered, changed, repealed or rescinded in any respect that would have the effect of in the case of any provision of this Agreement other than Section 11.2 or Section 13.4, reducing such percentage, unless such
amendment is approved by the written consent or the affirmative vote of holders of Outstanding Units whose aggregate Outstanding Units constitute not less than the voting requirement sought to be reduced or increased, as applicable or the
affirmative vote of Partners whose aggregate Percentage Interest constitutes not less than the voting requirement sought to be reduced, as applicable. 
 (b) Notwithstanding the provisions of Section 13.1 and Section 13.2, no amendment to this Agreement may (i) enlarge the obligations of (including requiring any holder of a
class of Partnership Interests to make additional Capital Contributions to the Partnership) 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, change or modify 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 Section 13.1 (this Section 13.3(c) being subject to 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. If the General Partner determines an amendment does not satisfy the requirements of Section 13.1(d)(i) because it adversely affects one or more classes of
Partnership Interests, as compared to other classes of Partnership Interests, in any material respect, such amendment shall only be required to be approved by the adversely affected class or classes. 

(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(b), no amendments shall become effective without the approval of the holders of at least 90% of the Percentage Interests of all Limited Partners 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 Partners
(including the General Partner and its Affiliates) holding at least 90% of the Percentage Interests of all Limited Partners. 

  
 114

 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 general or specific purposes for which the special meeting is to be called. 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 a notice of the meeting to the Limited Partners either directly or indirectly through the Transfer Agent. 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 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. 
 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. The notice shall be deemed to have been given at the time when deposited in the mail or sent by other means of
written communication. 
 Section 13.6 Record Date. 

For purposes of determining the Limited Partners 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 may 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 Limited Partners are requested in writing by the General Partner to give such approvals. If the
General Partner does not set a Record Date, then (a) the Record Date for determining the Limited Partners entitled to notice of or to vote at a meeting of the Limited Partners shall be the close of business on the day next preceding the day on
which notice is given, and (b) the Record Date for determining the Limited Partners entitled to give approvals without a meeting shall be the date the first written approval is deposited with the Partnership in care of the General Partner in
accordance with Section 13.11. 

  
 115

 Section 13.7 Adjournment. 

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 that 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; Approval of Minutes. 

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 waiver of any
right to disapprove the consideration of matters required to be included in the notice of the meeting, but not so included, if the disapproval is expressly made at the meeting. 

Section 13.9 Quorum and Voting. 
 The holders of a majority, by Percentage Interest, of the Partnership Interests of the class or classes for which a meeting has been called (including Partnership Interests deemed owned by the General
Partner) represented in person or by proxy shall constitute a quorum at a meeting of Partners of such class or classes unless any such action by the Partners requires approval by holders of a greater Percentage Interest, in which case the quorum
shall be such greater Percentage Interest. At any meeting of the Partners duly called and held in accordance with this Agreement at which a quorum is present, the act of Partners holding Partnership Interests that in the aggregate represent a
majority of the Percentage Interest of those present in person or by proxy at such meeting shall be deemed to constitute the act of all Partners, unless a greater or different percentage is required with respect to such action under the provisions
of this Agreement, in which case the act of the Partners holding Partnership Interests that in the aggregate represent at least such greater or different percentage shall be required; provided, however, that if, as a matter of law or
amendment to this Agreement, approval by plurality vote of Partners (or any class thereof) is required to approve any action, no minimum quorum shall be required. The Partners present at a duly called or held meeting at which a quorum is present may
continue to transact business until adjournment, notwithstanding the withdrawal of enough Partners to leave less than a quorum, if any action taken (other than adjournment) is approved by Partners holding the required Percentage Interest specified
in this Agreement. In the absence of a quorum any meeting of Partners may be adjourned from time to time by the affirmative vote of Partners with at least a majority, by Percentage Interest, of the Partnership Interests entitled to vote at such
meeting (including Partnership Interests deemed owned by the General Partner) represented either in person or by proxy, but no other business may be transacted, except as provided in Section 13.7. 

  
 116

 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 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, without a vote and without prior notice, if an approval in writing
setting forth the action so taken is signed by Limited Partners owning not less than the minimum percentage, by Percentage Interest, of the Partnership Interests of the class or classes for which a meeting has been called (including Partnership
Interests deemed owned by the General Partner), as the case may be, that would be necessary to authorize or take such action at a meeting at which all the Limited Partners entitled to vote at such meeting 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, if any, submitted to Limited
Partners for the purpose of taking any action without a meeting shall be returned to the 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 Units held by the Limited Partners, the Partnership shall be deemed to have failed to receive a ballot for the Units that were not voted. If approval of the taking of any 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) they are deposited with the Partnership in care of the General Partner and (b) 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. Nothing contained in this Section 13.11 shall be deemed to require the General Partner to solicit all Limited Partners in connection with a matter approved by the holders of the requisite Percentage Interest acting by
written consent without a meeting. 

  
 117

 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 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 (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), in whose
name such Units are registered, such other Person 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 it 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.

Partnership with or into another entity if (A) the General Partner has received an Opinion of Counsel that the merger or consolidation, as the case may be, would not result in the loss of the limited liability of any Limited Partner as compared
to its limited liability under the Delaware Act or cause the Partnership or any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for U.S. federal income tax purposes (to the extent not
already treated as such), (B) 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, (C) the Partnership is the Surviving Business

made pursuant to this Section 14.4 shall be effective at the effective time or date of the merger or consolidation.

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:

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;

of the conversion; 
 (iv) all rights of creditors or other parties with respect to or against the prior interest holders or

Conversion. 
 ARTICLE XV 
 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 80% 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 in its sole discretion, 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 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 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 Transfer Agent notice of such election to purchase (the “Notice of Election to Purchase”) and shall cause the Transfer Agent to mail a copy of such Notice of Election to Purchase to the
Record Holders of Limited Partner Interests of such class or classes (as of a Record Date selected by the General Partner) at least 10, but not more than 60, days prior to the Purchase Date. Such Notice of Election to Purchase shall also be
published for a period of at least three consecutive days in at least two daily newspapers of general circulation printed in the English language and published in the Borough of Manhattan, New York. 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 in exchange for payment, at such office or offices of the Transfer
Agent as the Transfer Agent may specify, or as may be required by any National Securities Exchange on which such Limited Partner Interests are listed or admitted to trading. Any such Notice of Election to Purchase mailed to a Record Holder of
Limited Partner Interests at his address as reflected in the records 

  
 123

 
of the Transfer Agent 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 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 shall not have been surrendered for purchase, all rights of the holders of such Limited Partner
Interests 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 of the
Certificates representing such Limited Partner Interests in the case of Limited Partner Interests evidenced by Certificates, 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 record books of the Transfer Agent and the Partnership, 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 owner of all such
Limited Partner Interests from and after the Purchase Date and shall have all rights as the owner of such Limited Partner Interests. 
 (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 in exchange for payment of the amount described in Section 15.1(a), therefor, without interest thereon.

unenforceable in any respect, the validity, legality and enforceability of the remaining provisions and part thereof contained herein shall not be affected thereby and this Agreement shall, to the fullest extent permitted by law, be reformed and
