1.Settlement. Settlement of vested RSUs shall be made within 30 days following the applicable date of vesting under the above vesting schedule (provided that if at the time of settlement Participant is a “specified employee” of the Company under Section 409A, and settlement would be treated as a payment made on separation of service, then if required to avoid the taxes imposed by Section 409A settlement shall be delayed by six (6) months (or if earlier, until death), or such other period of time as is then required to avoid such taxes. Notwithstanding any provision to the contrary in this agreement, to the extent necessary to avoid the imposition of any taxes under Section 409A, no payment or distribution under this agreement that becomes payable by reason of a Participant’s termination of employment with the Company will be made to such Participant unless such Participant’s termination of employment constitutes a “separation from service” (as such term is defined in Section 409A). For purposes of this agreement, each amount to be paid or benefit to be provided shall be construed as a separate identified payment for purposes of Section 409A.  Settlement of vested RSUs shall be in Shares; provided, that pursuant to Section 7, if Shares may not be withheld as a result of foreign tax law, then an appropriate number of RSUs may or may not be automatically settled in cash, depending upon the taxable jurisdiction.  In addition, if determined by the Committee in its discretion at the time of payment, RSUs may also be settled in cash or some combination of cash and Shares.  The Participant shall pay to the Company the aggregate par value of the Shares issued prior to their issuance (par value being $0.001 per Share) with such payment deemed to have been made for each Share, by Participant’s services from the Date of Grant to the first applicable vesting date. Participant agrees that, if necessary due to applicable law, Participant shall pay to the Company each affected Share’s par value by making appropriate payroll deductions from funds due the Participant.  Notwithstanding the issuance of Shares in settlement of the RSUs or the delivery of one or more stock certificates for such Shares, the Shares shall be subject to applicable restrictions on transfer or sale, if any, as may be set forth in the Participant’s written employment or service contract with the Company or pursuant to any policy adopted by the Company, now or hereafter existing, that imposes stock ownership requirements, stock retention requirements or stock sale restrictions on the Participant.  To enforce any restrictions or requirements on the Participant’s Shares, the Committee may require the Participant to deposit all certificates, together with stock powers or other instruments of transfer approved by the Committee appropriately endorsed in blank, with the Company or an agent designated by the Company to hold in escrow until such restrictions or requirements have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions or requirements to be placed on the certificates.
2. No Stockholder Rights. Unless and until such time as Shares are issued in settlement of vested RSUs, the Participant shall have no ownership of the Shares allocated to the RSUs and shall have no right to vote such Shares, subject to the terms, conditions and restrictions described in the Plan and herein. 
3. Dividend Equivalents. Any dividends paid in cash on Shares of the Company shall be credited to the Participant as additional RSUs as if the RSUs previously held by the Participant were outstanding Shares (in such number as determined by the Committee), as follows: such credit shall be made in whole and/or fractional RSUs and shall be based on the Fair Market Value of the Shares on the date of payment of such dividend. All such additional RSUs shall be subject to the same vesting requirements applicable to the RSUs in respect of which they were credited and shall be settled in accordance with, and at the time of, settlement of the vested RSUs to which they are related. 
4. No Transfer. The RSUs and any interest therein (i) shall not be sold, assigned, transferred, pledged, hypothecated, or otherwise disposed of, and (ii) shall, if the Participant’s continuous employment with the Company or any of its affiliates shall terminate for any reason (except as otherwise provided in the Plan or Section 5 below), be forfeited to the Company forthwith, and all the rights of the Participant to such RSUs shall immediately terminate. 
5. Termination. 
(i)    In the event of a Participant’s Termination by the Company or by the Participant, the Committee shall settle in Shares, the value of any vested RSUs (based on the then Fair Market Value of Shares deemed allocated to such vested RSUs on the date of such Termination, subject to Section 1 hereof. 
(ii)    In the event of a Participant’s Termination due solely to death or Disability while any RSUs granted hereunder remain unvested, all RSUs that are unvested as of such Termination shall immediately accelerate in full, and the Committee shall settle the value of such RSUs on the date of such Termination. Settlement of the RSUs shall be subject to Section 1 hereof. 
(iii)    In case of any dispute as to whether Termination has occurred, the Committee shall have sole discretion to determine whether such Termination has occurred and the effective date of such Termination. 

6. Acknowledgement. The Company and the Participant agree that the RSUs are granted under and governed by this Restricted Stock Unit Agreement and by the provisions of the Plan (incorporated herein by reference). The Participant: (i) acknowledges receipt of a copy of the Plan and the Plan prospectus, (ii) represents that the Participant has carefully read and is familiar with their provisions, and (iii) hereby accepts the RSUs subject to all of the terms and conditions set forth herein and those set forth in the Plan.  In the event that upon the 30th day after the Date of Grant, the Participant has not refused the RSUs by notice to the Company pursuant to Section 12 hereof, the Participant shall be deemed to have accepted the RSUs subject to all of the terms and conditions set forth herein and those set forth in the Plan.
7. Tax Consequences. The Participant acknowledges that there may be adverse tax consequences upon settlement of the RSUs or disposition of the Shares, if any, received in connection therewith and that the Company recommends that Participant should consult a tax adviser prior to such settlement or disposition. In particular, Participant must make arrangements, satisfactory to the Company, for satisfaction of any applicable foreign, federal, state or local income tax withholding requirements or social security requirements related to the grant of the RSUs or Participant’s receipt of Shares in settlement thereof, including, in either case, any dividend paid in respect thereof. In the event settlement of the RSUs is made in Shares, the Company will satisfy the minimum statutory withholding tax obligation by withholding a certain number of Shares otherwise deliverable from the total number of Shares deliverable to the Participant upon settlement unless Shares may not be withheld as a result of foreign tax law (in which case an appropriate number of RSUs may or may not be automatically settled in cash, depending upon the taxable jurisdiction). In the event that any RSUs are settled in cash, or Shares may not be withheld as a result of foreign tax law, the Participant hereby authorizes the Company to withhold the required minimum amount from Participant’s other sources of compensation from the Company or any Parent or Subsidiary. 
8. Compliance with Laws and Regulations. The issuance of Shares will be subject to and conditioned upon compliance by the Company and Participant with all applicable state and federal laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s Common Stock may be listed or quoted at the time of such issuance or transfer. 
9. VeriSign Incentive Compensation Recovery Policy in the Case of Inaccurate Financial Statements.  The Committee has adopted an incentive compensation recovery policy (the “Policy”) which applies to all Section 16 executive officers and such other officers as the Committee may designate.   The Policy applies whenever there is an inaccurate financial statement, and, as a result, a covered executive has received materially more incentive compensation than would have otherwise occurred.   To the extent you are subject to the Policy, you agree that the Committee has discretion to seek recovery of any such overpayment received under this Agreement per the terms of the Policy.
10. Successors and Assigns. The Company may assign any of its rights under this Agreement. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Agreement will be binding upon Participant and Participant’s heirs, executors, administrators, legal representatives, successors and assigns. 
11. Governing Law; Severability. This Agreement shall be governed by and construed in accordance with the internal laws of the Commonwealth of Virginia as such laws are applied to agreements between Virginia residents entered into and to be performed entirely within Virginia, excluding that body of laws pertaining to conflict of laws. If any provision of this Agreement is determined by a court of law to be illegal or unenforceable, then such provision will be enforced to the maximum extent possible and the other provisions will remain fully effective and enforceable. 
     
12. Notices. Any notice required to be given or delivered to the Company shall be in writing and addressed to the Corporate Secretary of the Company at its principal corporate offices. Any notice required to be given or delivered to Participant shall be in writing (including email) and addressed to Participant at the participant’s Company email address, the address of record or to such other address as Participant may designate in writing from time to time to the Company or may be posted on the Participant’s E*Trade VeriSign employee stock plan account at www.etrade.com. All notices shall be deemed effectively given upon personal delivery, (i) three (3) days after deposit in the United States mail by certified or registered mail (return receipt requested), (ii) one (1) business day after its deposit with any return receipt express courier (prepaid), (iii) one (1) business day after transmission by fax or telecopier, (iv) upon receipt if sent by the Company to the Participant’s email address at the Company, or (v) upon posting on the Participant’s E*Trade VeriSign employee stock plan account at www.etrade.com. 
13. Further Instruments. The parties agree to execute such further instruments and to take such further action as may be reasonably necessary to carry out the purposes and intent of this Agreement. 
14. Headings. The captions and headings of this Agreement are included for ease of reference only and are to be disregarded in interpreting or construing this Agreement. 

15. Entire Agreement; Modification. The Plan and this Restricted Stock Unit Agreement for these RSUs constitute the entire agreement and understanding of the parties with respect to the subject matter herein and supersede all prior understandings and agreements, whether oral or written, between the parties hereto with respect to the specific subject matter hereof.  This Restricted Stock Unit Agreement may be amended only by a written instrument executed by an authorized representative of the Company and effectively given to the Participant pursuant to the methods of delivery set forth in Section 12 above.  Any such amendment shall be deemed effective thirty (30) calendar days after the date on which it is effectively given to the Participant as described in Section 12 above, provided the Participant does not provide the Company with a written notice within that thirty (30) day period rejecting the amendment.

 THIRD AMENDED AND RESTATED AGREEMENT 

OF LIMITED PARTNERSHIP OF ENABLE MIDSTREAM PARTNERS, LP 

THIS THIRD AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP OF ENABLE MIDSTREAM PARTNERS, LP, dated as of February 18, 2016, is entered
into by and among ENABLE GP, LLC, a Delaware limited liability company, as the General Partner, together with any other Persons who are or become Partners in the Partnership or parties hereto as provided herein. In consideration of the
covenants, conditions and agreements contained herein, the parties hereto hereby agree as follows: 
 ARTICLE I 

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

“Acquisition” means any transaction in which any Group Member acquires (through an asset acquisition, stock acquisition,
merger or other form of investment) control over all or a portion of the assets, properties or business of another Person for the purpose of increasing, over the long-term, the asset base, operating capacity or operating income of the Partnership
Group from the asset base, operating capacity or operating income of the Partnership Group existing immediately prior to such transaction. For purposes of this definition, “long-term” generally refers to a period of not less than twelve
months. 
 “Additional Book Basis” means, with respect to any Adjusted Property, the portion of the Carrying Value of such
Adjusted Property that is attributable to positive adjustments made to such Carrying Value as determined in accordance with the provisions set forth below in this definition of Additional Book Basis. For purposes of determining the extent to which
Carrying Value constitutes Additional Book Basis: 
 (a) Any negative adjustment made to the Carrying Value of an Adjusted Property as a
result of either a Book-Down Event or a Book-Up Event shall first be deemed to offset or decrease that portion of the Carrying Value of such Adjusted Property that is attributable to any prior positive adjustments made thereto pursuant to a Book-Up
Event or Book-Down Event; and 
 (b) If Carrying Value that constitutes Additional Book Basis is reduced as a result of a Book-Down Event
and the Carrying Value of other property is increased as a result of such Book-Down Event, an allocable portion of any such increase in Carrying Value shall be treated as Additional Book Basis; provided, that the amount treated as Additional
Book Basis pursuant hereto as a result of such Book-Down Event shall not exceed the amount by which the Aggregate Remaining Net Positive Adjustments after such Book-Down Event exceeds the remaining Additional Book Basis attributable to all of the
Partnership’s Adjusted Property after such Book-Down Event (determined without regard to the application of this clause (b) to such Book-Down Event). 

  
 1 

 “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; provided that the provisions of the immediately
preceding sentence shall apply to the determination of the Additional Book Basis Derivative Items attributable to Disposed of Adjusted Property. 

“Adjusted Capital Account” means, with respect to any Partner, the balance in such Partner’s Capital Account at the end
of each taxable period of the Partnership, after giving effect to the following adjustments: (a) credit to such Capital Account any amounts that such Partner is (x) obligated to restore under the standards set by Treasury Regulation Section
1.704-1(b)(2)(ii)(c) or (y) deemed obligated to restore pursuant to the penultimate sentences of Treasury Regulation Sections 1.704-2(g)(1) and 1.704-2(i)(5); and (b) debit to such Capital Account the items described in Treasury Regulation Sections
1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) and 1.704-1(b)(2)(ii)(d)(6). The foregoing definition of Adjusted Capital Account is intended to comply with the provisions of Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted
consistently therewith. The “Adjusted Capital Account” of a Partner in respect of any Partnership Interest shall be the amount that such Adjusted Capital Account would be if such Partnership Interest were the only interest in the
Partnership held by such Partner from and after the date on which such Partnership Interest was first issued. 
 “Adjusted Operating
Surplus” means, with respect to any period, (a) Operating Surplus generated with respect to such period less (b)(i) the amount of any net increase in Working Capital Borrowings (or the Partnership’s proportionate share of any net
increase in Working Capital Borrowings in the case of Subsidiaries that are not wholly owned) with respect to such period and (ii) the amount of any net decrease in cash reserves (or the Partnership’s proportionate share of any net decrease in
cash reserves in the case of Subsidiaries that are not wholly owned) for Operating Expenditures with respect to such period not relating to an Operating Expenditure made with respect to such period, and plus (c)(i) the amount of any net decrease in
Working Capital Borrowings (or the Partnership’s proportionate share of any net decrease in Working Capital Borrowings in the case of Subsidiaries that are not wholly owned) with respect to such period, (ii) the amount of any net decrease made
in subsequent periods in cash reserves for Operating Expenditures initially established with respect to such period to the extent such decrease results in a reduction in Adjusted Operating Surplus in subsequent periods pursuant to clause (b)(ii)
above and (iii) the amount of any net increase in cash reserves (or the Partnership’s proportionate share of any net increase in cash reserves in the case of Subsidiaries that are not wholly owned) for Operating Expenditures with respect to
such period required by any debt instrument for the repayment of principal, interest or premium. Adjusted Operating Surplus does not include that portion of Operating Surplus included in clause (a)(i) of the definition of Operating Surplus;
provided, that to the extent that actual volumes of natural gas 

  
 2 

 
delivered to the gathering systems of the Partnership (associated with a Minimum Volume Commitment) in a particular Quarter or Quarters are less than the prorated (in Quarterly amounts) Minimum
Volume Commitment amount for such period, the General Partner may add to Adjusted Operating Surplus for such period an amount equal to such shortfall multiplied by the applicable gathering rate as set forth in the gathering or similar agreement (the
“Quarterly Estimated Shortfall Payment”). The Quarterly Estimated Shortfall Payment shall be adjusted each subsequent Quarter based on the level of actual volumes delivered for such subsequent Quarter and the preceding
Quarters of the period that remain subject to a Minimum Volume Commitment (as compared to the prorated Minimum Volume Commitment for such period). If the sum of Quarterly Estimated Shortfall Payments in respect of a Minimum Volume Commitment Period
is greater than the aggregate shortfall amount actually paid with respect to a Minimum Volume Commitment period as finally determined, and Subordinated Units remain outstanding, then Adjusted Operating Surplus shall be adjusted in each such Quarter
to give effect to the shortfall amount actually paid as if it had been paid in such Quarter to cover the shortfall in such Quarter. With respect to a Quarter in which a shortfall amount under a Minimum Volume Commitment is actually paid, Adjusted
Operating Surplus shall be reduced by an amount equal to the amount of Adjusted Operating Surplus previously added by the General Partner with respect to such Minimum Volume Commitment Period pursuant to this proviso. 

“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. Without limiting the foregoing, for purposes of this Agreement, any Person that, individually or together with its Affiliates, has the direct or
indirect right to designate or cause the designation of at least one member to the Board of Directors of the General Partner, and any such Person’s Affiliates, shall be deemed to be an Affiliate of the General Partner. Notwithstanding anything
in the foregoing to the contrary, CERC and its Affiliates (other than the General Partner or any Group Member), on the one hand, and OGEH and its Affiliates (other than the General Partner or any Group Member), on the other hand, will not be deemed
to be Affiliates of one another hereunder unless there is a basis for such Affiliation independent of their respective Affiliation with any Group Member, the General Partner or any Affiliate (disregarding the immediately preceding sentence) of any
Group Member or the General Partner. 
 “Aggregate Quantity of IDR Reset Common Units” is defined 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. 
 “Agreed Allocation” means any allocation, other than a Required Allocation, of
an item of income, gain, loss or deduction pursuant to the provisions of Section 6.1, including a Curative Allocation (if appropriate to the context in which the term “Agreed Allocation” is used). 

  
 3 

 “Agreed Value” of (a) a Contributed Property means the fair market value of such
property or other consideration at the time of contribution and (b) an Adjusted Property means the fair market value of such Adjusted Property on the date of the Revaluation Event, in each case as determined by the General Partner. The General
Partner shall use such method as it determines to be appropriate to allocate the aggregate Agreed Value of Contributed Properties contributed to the Partnership in a single or integrated transaction among each separate property on a basis
proportional to the fair market value of each Contributed Property. 
 “Agreement” means this Third Amended and Restated
Agreement of Limited Partnership of Enable Midstream Partners, LP, as it may be amended, supplemented or restated from time to time. 

“Alternative Conversion Consideration” is defined in Section 16.4(c).

and including the last day of the most recently completed Quarter have not been paid on all Outstanding Series B Preferred Units.

assets of the Partnership and its subsidiaries taken as a whole in a single transaction or a series of related transactions that is subject to the approval of the Limited Partners pursuant to Section 7.3 or (b) any merger, consolidation or
conversion of the Partnership that is subject to the approval of the Limited Partners pursuant to Article XIV, in the case of (a) and (b) that is not a Series A Change of Control or a Series B Change of Control. 

“Associate” means, when used to indicate a relationship with any Person, (a) any corporation or organization of which such
Person is a director, officer, manager, general partner or managing member or is, directly or indirectly, the owner of 20% or more of any class of voting stock or other voting interest, (b) any trust or other estate in which such Person has at least
a 20% beneficial interest or as to which 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. 

“Available Cash” means, with respect to any Quarter ending prior to the Liquidation Date: 

(a) the sum of: 
 (i) all cash

(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, less;

 (b) the amount of any cash reserves established by the General Partner (or the Partnership’s
proportionate share of cash reserves in the case of Subsidiaries that are not wholly owned) to:

the business of the Partnership Group (including cash reserves for future capital expenditures, future acquisitions, and for anticipated future debt service requirements 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) 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; 

(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; 

(iv) provide funds for Series A Payments; or 

(iv) provide funds for Series B Payments; 

provided, however, that the General Partner may not establish cash reserves pursuant to subclause (iii) above if the effect of 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

Restated Agreement of Limited Partnership of Enable Midstream Partners, LP, as amended, in its entirety on April 16, 2014. The General Partner hereby amends and restates the Second Amended and Restated Agreement of Limited Partnership of Enable
Midstream Partners, LP, as amended, in its entirety pursuant to Section 13.1(d) and Section 13.1(g) thereof. This amendment and restatement shall become effective on the date of this Agreement. Except as expressly provided to the contrary
in this Agreement, the rights, duties, liabilities and obligations of the Partners and the administration, dissolution and termination of the Partnership shall be governed by the Delaware Act. All Partnership Interests shall constitute personal
property of the record owner thereof for all purposes. 
 Section 2.2 Name. The name of the Partnership shall be “Enable
Midstream Partners, LP”. Subject to applicable law, the Partnership’s business may be conducted under any other name or names as determined by the General Partner, including the name of the General Partner. The words “Limited
Partnership,” “L.P.,” “Ltd.” or similar words or letters shall be included in the Partnership’s name where necessary for the purpose of complying with the laws of any jurisdiction that so requires. The General Partner
may change the name of the Partnership at any time and from time to time and shall notify the Limited Partners of such change in the next regular communication to the Limited Partners.

principal office of the Partnership shall be located at One Leadership Square, 211 North Robinson Avenue, Suite 150, Oklahoma City, Oklahoma 73102, or such place as the General Partner may from
time to time designate by notice to the Limited Partners. The Partnership may maintain offices at such other place or places within or outside the State of Delaware as the General Partner determines to be necessary or appropriate. The
address of the General Partner shall be One Leadership Square, 211 North Robinson Avenue, Suite 150, Oklahoma City, Oklahoma 73102, or such place as the General Partner may from time to time designate by notice to the Limited Partners. 

Section 2.4 Purpose and Business. The purpose and nature of the business to be conducted by the Partnership shall be to (a) engage
directly in, or enter into or form, hold and dispose of any corporation, partnership, joint venture, limited liability company or other arrangement to engage indirectly in, any business activity that is approved by the General Partner and that
lawfully may be conducted by a limited partnership organized pursuant to the Delaware Act and, in 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 activity that the General Partner determines would be reasonably likely to cause the Partnership to be treated as an association taxable as a corporation or otherwise taxable as an entity for federal income
tax purposes. To the fullest extent permitted by law, the General Partner shall have no duty or obligation to propose or approve the conduct by the Partnership of any business and may decline to do so free of any duty or obligation whatsoever
to the Partnership or any Limited Partner and, in declining to so propose or approve, shall not be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement
contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity and the General Partner in determining whether to propose or approve the conduct by the Partnership of any business shall be permitted to do so in its
sole and absolute discretion. 
 Section 2.5 Powers. The Partnership shall be empowered to do any and all acts and things
necessary, appropriate, proper, advisable, incidental to or convenient for the furtherance and accomplishment of the purposes and business described in Section 2.4 and for the protection and benefit of the Partnership. 

Section 2.6 Term. The term of the Partnership commenced upon the filing of its certificate of limited liability company in
accordance with the Delaware LLC Act, was uninterrupted by the filing of its Certificate of Limited Partnership in accordance with Section 17-217 of the Delaware Act and shall continue until the dissolution of the Partnership in accordance with the
provisions of Article XII. The existence of the Partnership as a separate legal entity shall continue until the cancellation of the Certificate of Limited Partnership as provided in the Delaware Act.

 Section 2.7 Title to Partnership Assets. Title to the assets of the Partnership,
whether real, personal or mixed and whether tangible or intangible, shall be deemed to be owned by the Partnership as an entity, and no Partner, individually or collectively, shall have any ownership interest in such assets of the Partnership or any
portion thereof. Title to any or all assets of the Partnership may be held in the name of the Partnership, the General Partner, one or more of its Affiliates or one or more nominees of the General Partner or its Affiliates, as the General Partner
may determine. The General Partner hereby declares and warrants that any assets of the Partnership for which record title is held in the name of the General Partner or one or more of its Affiliates or one or more nominees of the General Partner or
its Affiliates shall be held by the General Partner or such Affiliate or nominee for the use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, however, that the General Partner shall use
reasonable efforts to cause record title to such assets (other than those assets in respect of which the General Partner determines that the expense and difficulty of conveyancing makes transfer of record title to the Partnership impracticable) to
be vested in the Partnership or one or more of the Partnership’s designated Affiliates as soon as reasonably practicable; provided, further, that, prior to the withdrawal or removal of the General Partner or as soon thereafter as
practicable, the General Partner shall use reasonable efforts to effect the transfer of record title to the Partnership and, prior to any such transfer, will provide for the use of such assets in a manner satisfactory to any successor General
Partner. All assets of the Partnership shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which record title to such assets of the Partnership is held. 

Section 2.8 Power of Attorney 

(a) Each Limited Partner hereby constitutes and appoints the General Partner and, if a Liquidator shall have been selected pursuant to Section
12.3, the Liquidator (and any successor to the Liquidator by merger, transfer, assignment, election or otherwise) and each of their authorized officers and attorneys-in-fact, as the case may be, with full power of substitution, as its true and
lawful agent and attorney-in-fact, with full power and authority in its name, place and stead, to: 
 (i) execute, swear to,
acknowledge, deliver, file and record in the appropriate public offices (A) all certificates, documents and other instruments (including this Agreement and the Certificate of Limited Partnership and all amendments or restatements hereof or thereof)
that the General Partner or the Liquidator determines to be necessary or appropriate to form, qualify or continue the existence or qualification of the Partnership as a limited partnership (or a partnership in which the limited partners have limited
liability) in the State of Delaware and in all other jurisdictions in which the Partnership may conduct business or own property; (B) all certificates, documents and other instruments that the General Partner or the Liquidator determines to be
necessary or appropriate to reflect, in accordance with its terms, any amendment, change, modification or restatement of this Agreement; (C) all certificates, documents and other instruments (including conveyances and a certificate of cancellation)
that the General Partner or the Liquidator determines to be necessary or appropriate to reflect the dissolution and liquidation of the Partnership pursuant to the terms of this Agreement; (D) all certificates,

  
 35 

 
documents and other instruments relating to the admission, withdrawal, removal or substitution of any Partner pursuant to, or other events described in, Article IV, Article X, Article XI or
Article XII; (E) all certificates, documents and other instruments relating to the determination of the rights, preferences and privileges of any class or series of Partnership Interests issued pursuant to Section 5.6; and (F) all certificates,

(ii) execute, swear to, acknowledge, deliver, file and record all ballots, consents, approvals, waivers, certificates,
documents and other instruments that the General Partner or the Liquidator determines to be necessary or appropriate to (A) make, evidence, give, confirm or ratify any vote, consent, approval, agreement or other action that is made or given by the
Partners hereunder or is consistent with the terms of this Agreement or (B) effectuate the terms or intent of this Agreement; provided, that when required by Section 13.3 or any other provision of this Agreement that establishes a percentage
of the Limited Partners or of the Limited Partners of any class or series required to take any action, the General Partner and the Liquidator may exercise the power of attorney made in this Section 2.8(a)(ii) only after the necessary vote, consent
or approval of the Limited Partners or of the Limited Partners of such class or series, as applicable. 
 Nothing contained in this Section
2.8(a) shall be construed as authorizing the General Partner to amend this Agreement except in accordance with Article XIII or as may be otherwise expressly provided for in this Agreement. 

(b) The foregoing power of attorney is hereby declared to be irrevocable and a power coupled with an interest, and it shall survive and, to
the maximum extent permitted by law, not be affected by, the subsequent death, incompetency, disability, incapacity, dissolution, bankruptcy or termination of any Limited Partner and the transfer of all or any portion of such Limited Partner’s
Limited Partner Interest and shall extend to such Limited Partner’s heirs, successors, assigns and personal representatives. Each such Limited Partner hereby agrees to be bound by any representation made by the General Partner or the Liquidator
acting in good faith pursuant to such power of attorney, and each such Limited Partner, to the maximum extent permitted by law, hereby waives any and all defenses that may be available to contest, negate or disaffirm the action of the General
Partner or the Liquidator taken in good faith under such power of attorney. Each Limited Partner shall execute and deliver to the General Partner or the Liquidator, within 15 days after receipt of the request therefor, such further designation,
powers of attorney and other instruments as the General Partner or the Liquidator may request in order to effectuate this Agreement and the purposes of the Partnership. 

ARTICLE III 
 RIGHTS OF
LIMITED PARTNERS 
 Section 3.1 Limitation of Liability. The Limited Partners shall have no liability under this Agreement
except as expressly provided in this Agreement or the Delaware Act. 

  
 36 

 Section 3.2 Management of Business. No Limited Partner, in its capacity as such, shall
participate in the operation, management or control (within the meaning of the Delaware Act) of the Partnership’s business, transact any business in the Partnership’s name or have the power to sign documents for or otherwise bind the
Partnership. No action taken by any Affiliate of the General Partner or any officer, director, employee, manager, member, general partner, agent or trustee of the General Partner or any of its Affiliates, or any officer, director, employee, manager,
member, general partner, agent or trustee of a Group Member, in its capacity as such, shall be deemed to be participating in the control of the business of the Partnership by a limited partner of the Partnership (within the meaning of Section
17-303(a) of the Delaware Act) nor shall any such action affect, impair or eliminate the limitations on the liability of the Limited Partners under this Agreement. 

Section 3.3 Rights of Limited Partners. 

(a) Each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a Limited Partner
in the Partnership, upon reasonable written demand stating the purpose of such demand, and at such Limited Partner’s own expense: 

(i) to obtain from the General Partner either (A) the Partnership’s most recent filings with the Commission on Form 10-K
and any subsequent filings on Form 10-Q and 8-K or (B) if the Partnership is no longer subject to the reporting requirements of the Exchange Act, the information specified in, and meeting the requirements of, Rule 144A(d)(4) under the Securities Act
or any successor or similar rule or regulation under the Securities Act (provided that the foregoing materials shall be deemed to be available to a Limited Partner in satisfaction of the requirements of this Section 3.3(a)(i) if posted on or
accessible through the Partnership’s or the Commission’s website); 
 (ii) to obtain a current list of the name and
last known business, residence or mailing address of each Partner; and 
 (iii) to obtain a copy of this Agreement and the
Certificate of Limited Partnership and all amendments thereto. 
 (b) The rights to information granted the Limited Partners pursuant to
Section 3.3(a) replace in their entirety any rights to information provided for in Section 17-305(a) of the Delaware Act and each of the Partners and each other Person or Group who acquires an interest in Partnership Interests hereby agrees to the
fullest extent permitted by law that they do not have any rights as Partners to receive any information either pursuant to Sections 17-305(a) of the Delaware Act or otherwise except for the information identified in Section 3.3(a). 

  
 37 

 (c) The General Partner may keep confidential from the Limited Partners, for such period of time
as the General Partner deems reasonable, (i) any information that the General Partner reasonably believes to be in the nature of trade secrets or (ii) other information the disclosure of which the General Partner in good faith believes (A) is not in
the best interests of the Partnership Group, (B) could damage the Partnership Group or its business or (C) that any Group Member is required by law or regulation or by agreement with any third party to keep confidential (other than agreements with
Affiliates of the Partnership the primary purpose of which is to circumvent the obligations set forth in this Section 3.3). 
 (d)
Notwithstanding any other provision of this Agreement or Section 17-305 of the Delaware Act, each of the Partners, each other Person or Group who acquires an interest in a Partnership Interest and each other Person bound by this Agreement hereby
agrees to the fullest extent permitted by law that they do not have rights to receive information from the Partnership or any Indemnitee for the purpose of determining whether to pursue litigation or assist in pending litigation against the
Partnership or any Indemnitee relating to the affairs of the Partnership except pursuant to the applicable rules of discovery relating to litigation commenced by such Person or Group. 

ARTICLE IV 

CERTIFICATES; RECORD HOLDERS; TRANSFER OF PARTNERSHIP INTERESTS; REDEMPTION OF PARTNERSHIP INTERESTS 

Section 4.1 Certificates. Owners of Partnership Interests and, where appropriate, Derivative Partnership Interests, shall be
recorded in the Register and ownership of such interests shall be evidenced by a physical certificate or book entry notation in the Register. Notwithstanding anything to the contrary in this Agreement, unless the General Partner shall determine
otherwise in respect of some or all of any or all classes of Partnership Interests and Derivative Partnership Interests or as otherwise set forth herein, Partnership Interests and Derivative Partnership Interests shall not be evidenced by physical
certificates. Certificates, if any, shall be executed on behalf of the Partnership by the Chief Executive Officer, President, Chief Financial Officer or any Vice President and the Secretary, any Assistant Secretary, or other authorized officer of
the General Partner, and shall bear the legend set forth in Section 4.8(f). The signatures of such officers upon a certificate may be facsimiles. In case any officer who has signed or whose signature has been placed upon such certificate
shall have ceased to be such officer before such certificate is issued, it may be issued by the Partnership with the same effect as if he were such officer at the date of its issuance. If a Transfer Agent has been appointed for a class of
Partnership Interests, no Certificate for such class of Partnership Interests shall be valid for any purpose until it has been countersigned by the Transfer Agent; 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(b) and 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 

  
 38 

 
Subordinated Units are evidenced by Certificates, may exchange such Certificates for Certificates evidencing the Common Units into which such Record Holder’s Subordinated Units converted, or
(ii) if the Subordinated Units are not evidenced by Certificates, shall be issued Certificates evidencing the Common Units into which such Record Holders’ Subordinated Units converted. Subject to Article XVI and Article XVII, with respect to
any Partnership Interests that are represented by physical certificates, the General Partner may determine that such Partnership Interests will no longer be represented by physical certificates and may, upon written notice to the holders of such
Partnership Interests and subject to applicable law, take whatever actions it deems necessary or appropriate to cause such Partnership Interests to be registered in book entry or global form and may cause such physical certificates to be cancelled
or deemed cancelled. 
 Section 4.2 Mutilated, Destroyed, Lost or Stolen Certificates. 

(a) If any mutilated Certificate is surrendered to the Transfer Agent, the appropriate officers of the General Partner on behalf of the
Partnership shall execute, and the Transfer Agent shall countersign and deliver in exchange therefor, a new Certificate evidencing the same number and type of Partnership Interests or Derivative 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 shall countersign, a new Certificate in place of any Certificate previously issued, 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 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 or the Transfer Agent. 
 If a Limited Partner fails to notify the General Partner within a reasonable period of time after
such Limited Partner has notice of the loss, destruction or theft of a Certificate, and a transfer of the Limited Partner Interests represented by the Certificate is registered before the Partnership, the General Partner or the Transfer Agent
receives such notification, to the fullest extent permitted by law, the Limited Partner shall be precluded from making any claim against the Partnership, the General Partner or the Transfer Agent for such transfer or for a new Certificate. 

(c) As a condition to the issuance of any new Certificate under this Section 4.2, the General Partner may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Transfer Agent) reasonably connected therewith. 

  
 39 

 Section 4.3 Record Holders. The names and addresses of holders of Partnership
Interests as they appear in the Register shall be the official list of Record Holders of the Partnership Interests for all purposes. The Partnership and the General Partner 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 or Group, regardless of whether the Partnership or the
General Partner 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 or Group in acquiring and/or holding Partnership Interests, as between the Partnership on the one hand, and such other Person on the other hand, such representative Person shall be the Limited Partner with respect to such Partnership
Interest upon becoming the Record Holder in accordance with Section 10.1(b) and have the rights and obligations of a Partner hereunder as, and to the extent, provided herein, including Section 10.1(c). 

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 all or any part of its General Partner Interest to another Person or by which a holder of Incentive Distribution Rights assigns all or any part of its Incentive Distribution Rights to another Person, and includes a
transfer, sale, assignment, gift, Encumbrance, hypothecation, exchange or any other disposition by law or otherwise or (ii) by which the holder of a Limited Partner Interest (other than an Incentive Distribution Right) makes any direct or indirect
transfer, sale, assignment, gift, Encumbrance, hypothecation, exchange or any other disposition by law or otherwise and, without limiting the generality of the foregoing, any distribution, transfer, assignment or other disposition of any Limited
Partner Interest, whether voluntary, involuntary or pursuant to any dissolution, liquidation or termination of such Person, to such Person’s members, stockholders, partners or other interestholders shall constitute a “transfer” of a
Limited Partner Interest (for the avoidance of doubt, with respect to a Limited Partner, any transfer, sale, assignment, gift, Encumbrance, hypothecation, exchange or other disposition of any interest in such Limited Partner, by such Limited Partner
or any interestholder of such Limited Partner shall be deemed to be an indirect Transfer of a Limited Partner Interest hereunder); provided, however, that any transfer of all or substantially all the assets, or a Change in Control, of CNP or
OGE shall not be a “transfer” hereunder. 

  
 40 

 (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 null and void, and the Partnership shall have no obligation to effect or
recognize any such transfer or purported transfer. The Partnership may issue stop transfer instructions to any Transfer Agent in order to implement any restriction on transfer contemplated by this Agreement. 

(c) Nothing contained in this Agreement shall be construed to prevent or limit a disposition by any stockholder, member, partner or other
owner of the General Partner of any or all of the shares of stock, membership interests, partnership interests or other ownership interests in the General Partner and the term “transfer” shall not include any such disposition. 

Section 4.5 Registration and Transfer of Limited Partner Interests. 

(a) The General Partner shall keep, or cause to be kept by the Transfer Agent on behalf of the Partnership, one or more registers in which,
subject to such reasonable regulations as it may prescribe and subject to the provisions of Section 4.5(b), the registration and transfer of Limited Partner Interests, and any Derivative Partnership Interests as applicable, shall be recorded (the
“Register”). 
 (b) The General Partner 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 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 and any other expenses (including the fees and
expenses of the Transfer Agent) reasonably connected therewith. Upon surrender of a Certificate for registration of transfer of any Limited Partner Interests evidenced by a Certificate, and subject to the provisions of this Section 4.5(b), the
appropriate officers of the General Partner on behalf of the Partnership shall execute and deliver, and in the case of Certificates evidencing Limited Partner Interests for which a Transfer Agent has been appointed, the Transfer Agent shall
countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Certificates evidencing the same aggregate number and type of Limited Partner
Interests as was evidenced by the Certificate so surrendered. Upon the proper surrender of a Certificate, such transfer shall be recorded in the Register. 

(c) Except as provided in Section 4.9, by acceptance of any Limited Partner Interests pursuant to a transfer in accordance with this Article
IV, each transferee of a Limited Partner Interest (including any nominee, or agent or representative acquiring such Limited Partner Interests for the account of another Person or Group) (i) shall be admitted to the Partnership as a Limited Partner
with respect to the Limited Partner Interests so transferred to such Person when any such transfer or admission is reflected in the Register and such Person becomes the Record Holder of the Limited Partner Interests so transferred, (ii) shall become
bound, and shall be deemed to have agreed to be bound, by the terms of this Agreement, (iii) shall be deemed to 

  
 41 

 
represent that the transferee has the capacity, power and authority to enter into this Agreement and (iv) shall be deemed to make any consents, acknowledgements or waivers contained in this
Agreement, all with or without execution of this Agreement by such Person. The transfer of any Limited Partner Interests and the admission of any new Limited Partner shall not constitute an amendment to this Agreement. 

(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. 
 Section 4.6 Transfer of the General
Partner’s General Partner Interest. 
 (a) Subject to Section 4.6(b) and (c), the General Partner may at its option
transfer all or any part of its General Partner Interest without Unitholder approval or the approval of the holders of the Incentive Distribution Rights. 

(b) Subject to Section 4.6(c), the General Partner shall not transfer all or any part of its General Partner Interest to any Person without
the prior approval of all members of the Board of Directors. 
 (c) Notwithstanding anything herein to the contrary, no transfer by the
General Partner of all or any part of its General Partner Interest to another Person shall be permitted unless (i) the transferee agrees to assume the rights and duties of the General Partner under this Agreement and to be bound by the provisions of
this Agreement, (ii) the Partnership receives an Opinion of Counsel that such transfer would not result in the loss of limited liability of any Limited Partner under the Delaware Act or cause the Partnership to be treated as an association taxable
as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed) and (iii) such transferee also agrees to purchase all (or the appropriate portion thereof, if applicable) of the
partnership or membership interest of 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. 
 (d) The General Partner shall not transfer all or any EH Management Units to any Person without the
prior approval of all members of the Board of Directors; provided, that the General Partner shall transfer all of the EH Management Units to any successor General Partner elected in accordance with the terms of this Agreement as a condition to the
election of such successor. 
 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. 

  
 42 

 Section 4.8 Restrictions on Transfers. 

(a) Except as provided in Section 4.8(e), notwithstanding the other provisions of this Article IV, no transfer of any Partnership Interests
shall be made if such transfer would (i) violate the then applicable federal or state securities laws or rules and regulations of the Commission, any state securities commission or any other governmental authority with jurisdiction over such
transfer, (ii) terminate the existence or qualification of the Partnership under the laws of the jurisdiction of its formation, or (iii) cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an
entity for federal income tax purposes (to the extent not already so treated or taxed). 
 (b) Except for a Permitted Transfer or as
provided in Section 4.11(c) or Section 4.12(c), no Common Units or Subordinated Units may be transferred, in whole or in part, by a Sponsor Party unless the Sponsor Party purporting to transfer such Common Units or Subordinated Units first complies
with the applicable provisions of Sections 4.11 and 4.12. 
 (c) The General Partner may impose restrictions on the transfer of Partnership
Interests if it receives an Opinion of Counsel that such restrictions are necessary to (i) avoid a significant risk of the Partnership becoming taxable as a corporation or otherwise becoming taxable as an entity for federal income tax purposes (to
the extent not already so treated or taxed) or (ii) preserve the uniformity of the Limited Partner Interests (or any class or classes thereof). The General Partner may impose such restrictions by amending this Agreement; provided,
however, that any amendment that would result in the delisting or suspension of trading of any class of Limited Partner Interests on the principal National Securities Exchange on which such class of Limited Partner Interests is then listed or
admitted to trading must be approved, prior to such amendment being effected, by the holders of at least a majority of the Outstanding Limited Partner Interests of such class. 

(d) The transfer of an IDR Reset Common Unit that was issued in connection with an IDR Reset Election pursuant to Section 5.11 shall be
subject to the restrictions imposed by Section 6.8(b) and Section 6.8(c). The transfer of a Subordinated Unit or a Common Unit issued upon conversion of a Subordinated Unit shall be subject to the restrictions imposed by Section 6.7(b) and Section
6.7(c). 
 (e) Except for Section 4.9, nothing contained in this Article IV, or elsewhere in this Agreement, shall preclude the settlement
of any transactions involving Partnership Interests entered into through the facilities of any National Securities Exchange on which such Partnership Interests are listed or admitted to trading. 

  
 43 

 (f) Each certificate evidencing any Series A Preferred Units shall bear a conspicuous legend in
substantially the form set forth in the second paragraph of the form of certificate attached hereto as Exhibit B, each certificate evidencing any Series B Preferred Units shall bear a conspicuous legend in substantially the form set forth in the
second paragraph of the form of certificate attached hereto as Exhibit C and any other certificate or book-entry evidencing Partnership Interests shall bear a conspicuous legend in substantially the following form: 

THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF ENABLE MIDSTREAM PARTNERS, LP THAT THIS SECURITY MAY NOT BE SOLD, OFFERED, RESOLD,
PLEDGED OR OTHERWISE TRANSFERRED IF SUCH TRANSFER WOULD (A) VIOLATE THE THEN APPLICABLE FEDERAL OR STATE SECURITIES LAWS OR RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER GOVERNMENTAL
AUTHORITY WITH JURISDICTION OVER SUCH TRANSFER, (B) TERMINATE THE EXISTENCE OR QUALIFICATION OF ENABLE MIDSTREAM PARTNERS, LP UNDER THE LAWS OF THE STATE OF DELAWARE, OR (C) CAUSE ENABLE MIDSTREAM PARTNERS, LP TO BE TREATED AS AN
ASSOCIATION TAXABLE AS A CORPORATION OR OTHERWISE TO BE TAXED AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES (TO THE EXTENT NOT ALREADY SO TREATED OR TAXED). ENABLE GP, LLC, THE GENERAL PARTNER OF ENABLE MIDSTREAM PARTNERS, LP, MAY IMPOSE
ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO (A) AVOID A SIGNIFICANT RISK OF ENABLE MIDSTREAM PARTNERS, LP BECOMING TAXABLE AS A CORPORATION OR OTHERWISE
BECOMING TAXABLE AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES OR (B) IN THE CASE OF LIMITED PARTNER INTERESTS, TO PRESERVE THE UNIFORMITY THEREOF (OR ANY CLASS OR CLASSES OF LIMITED PARTNER INTERESTS). THIS SECURITY MAY BE SUBJECT TO
ADDITIONAL RESTRICTIONS ON ITS TRANSFER PROVIDED IN THE PARTNERSHIP AGREEMENT. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS SECURITY TO THE SECRETARY OF THE GENERAL PARTNER AT THE
PRINCIPAL OFFICE OF THE PARTNERSHIP. THE RESTRICTIONS SET FORTH ABOVE SHALL NOT PRECLUDE THE SETTLEMENT OF ANY TRANSACTIONS INVOLVING THIS SECURITY ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY
IS LISTED OR ADMITTED TO TRADING. 
 Section 4.9 Eligibility 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 an 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 one or more Limited Partners (a “Citizenship Eligibility
Trigger”); 

  
 44 

 then, (x) in the case of a Rate Eligibility Trigger, the General Partner may 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, the General Partner may obtain such proof of the nationality, citizenship or other related
status of the Limited Partners (or, if any Limited 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 Limited Partners whose nationality, citizenship or other related status 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) Without limitation of the foregoing, the General Partner may require all Limited 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 Limited Partner Interests to so certify prior to being admitted to the Partnership as a Limited Partner
(any such required certificate, an “Eligibility Certificate”). 
 (c) If any Limited Partner fails to furnish to the
General Partner an Eligibility Certificate or other requested information of its (and its beneficial owners’) status as an Eligible Holder within thirty (30) days (or such other period as the General Partner may determine) of receipt of a
request from the General Partner to furnish an Eligibility Certificate or other requested information, or if upon receipt of such Eligibility Certificate or other requested information the General Partner determines that a Limited Partner or a
transferee of a Limited Partner is not an Eligible Holder (such a Partner, an “Ineligible Holder”), the Limited Partner Interests owned by such Limited Partner shall be subject to redemption in accordance with the provisions
of Section 4.10 or the General Partner may refuse to effect the transfer of the Limited Partner Interests to such transferee. In addition, the General Partner shall be substituted for any Limited Partner that is an Ineligible Holder as the Limited
Partner in respect of the Ineligible Holder’s Limited Partner Interests. 
 (d) The General Partner shall, in exercising voting rights
in respect of Limited Partner Interests held by it on behalf of Ineligible Holders, distribute the votes in the same ratios as the votes of Limited Partners (including the General Partner and its Affiliates) in respect of Limited Partner Interests
other than those of Ineligible Holders are cast, either for, against or abstaining as to the matter. 
 (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 its Limited Partner Interest (representing the right to
receive its share of such distribution in kind). 
 (f) At any time after an Ineligible Holder can and does certify that it no longer is an
Ineligible Holder, it may, upon application to the General Partner, request that with respect to any Limited Partner Interests of such Ineligible Holder not redeemed pursuant to Section 4.10, such Ineligible Holder be admitted as a Limited Partner,
and upon approval of the General Partner, such Ineligible Holder shall be admitted as 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
Limited Partner Interests.

 Section 4.10 Redemption of Partnership Interests of Ineligible Holders. 

(a) If at any time a Limited Partner fails to furnish an Eligibility Certificate or any information requested within thirty (30) days (or such
other period as the General Partner may determine) of receipt of a request from the General Partner to furnish an Eligibility Certificate, or if upon receipt of such Eligibility Certificate or such other information the General Partner determines,
with the advice of counsel, that a Limited Partner is an Ineligible Holder, the Partnership may, unless the Limited Partner establishes to the satisfaction of the General Partner that such Limited Partner is not an Ineligible Holder or has
transferred his Limited Partner Interests to a Person who is not an Ineligible Holder and who furnishes an Eligibility Certificate to the General Partner prior to the date fixed for redemption as provided below, redeem the Limited Partner Interest
of such Limited Partner as follows: 
 (i) The General Partner shall, not later than the 30th day before the date fixed for
redemption, give notice of redemption to the Limited Partner, at his last address designated in the Register 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 at the place specified in the notice) and that on and after the date fixed for redemption no further allocations or distributions to which the Limited Partner would otherwise be
entitled in respect of the Redeemable Interests will accrue or be made. 
 (ii) The aggregate redemption price for Redeemable
Interests shall be an amount equal to the Current Market Price (the date of determination of which shall be the date fixed for redemption) of Limited Partner Interests of the class to be so redeemed multiplied by the number of Limited Partner
Interests of each such class included among the Redeemable Interests. The redemption price shall be paid, as determined by the General Partner, in cash or by delivery of a promissory note of the Partnership in the principal amount of the redemption
price, bearing interest at the rate of 5% annually and payable in three equal annual installments of principal together with accrued interest, commencing one year after the redemption date. 

(iii) The Limited Partner or his duly authorized representative shall be entitled to receive the payment for the Redeemable
Interests at the place of payment specified in 

  
 46 

 
the notice of redemption on the redemption date (or, if later in the case of Redeemable Interests evidenced by Certificates, upon surrender by or on behalf of the Limited Partner or transferee at
the place specified in the notice of redemption, of the 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 Limited Partner
Interests. 
 (b) The provisions of this Section 4.10 shall also be applicable to Limited Partner Interests held by a Limited Partner as
nominee, agent or representative of a Person determined to be an Ineligible Holder. 
 (c) Nothing in this Section 4.10 shall prevent the
recipient of a notice of redemption from transferring his Limited Partner Interest before the redemption date if such transfer is otherwise permitted under this Agreement and the transferor provides notice of such transfer to the General Partner.
Upon receipt of notice of such a transfer, the General Partner shall withdraw the notice of redemption, provided that the transferee of such Limited Partner Interest certifies to the satisfaction of the General Partner that such transferee is not an
Ineligible Holder. If the transferee fails to make such certification within 30 days after the request, and, in any event, before the redemption date, such redemption shall be effected from the transferee on the original redemption date. 

Section 4.11 Sponsor Party Right of First Offer. 

(a) Subject to Section 4.8 and Section 4.11(c), except for a Permitted Transfer or a transfer to which Section 4.12 applies, if a Sponsor
Party (a “ROFO Seller”) wishes to solicit proposals from third parties to acquire all or any portion of the ROFO Seller’s Common Units or Subordinated Units, the ROFO Seller shall first provide a written notice (the
“ROFO Notice”) to each other Sponsor Party (or, in the case of a transfer of Subordinated Units, only to the other Sponsor Parties holding Subordinated Units), with a copy to the Partnership, containing: (i) the number of
Common Units or Subordinated Units proposed to be transferred (the “ROFO Units”) and (ii) a request for each other Sponsor Party entitled to receive such notice (each, a “ROFO Non-Selling Limited
Partner”) to specify the purchase price (the “ROFO Price”) and other terms and conditions on which such ROFO Non-Selling Limited Partner is willing to purchase the ROFO Units. 

(b) The following procedures shall apply: 

(i) Within thirty (30) days after receiving the ROFO Notice, one or more ROFO Non-Selling Limited Partners (each, a
“ROFO Accepting Limited Partner” and, collectively, the “ROFO Accepting Limited Partners”) may elect in writing (the “ROFO Offer Notice”) to purchase all, but not less than all,
of the ROFO Units. The ROFO Offer Notice shall specify the ROFO Price and other terms and conditions on which such ROFO Non-Selling Limited Partner is willing to purchase the ROFO Units. If any ROFO Accepting Limited Partner submits a ROFO Offer
Notice within the time period specified herein, the ROFO Seller shall have thirty (30) days from the date it received the ROFO Offer Notice to elect in writing (the “ROFO Acceptance Notice”) to accept the ROFO Accepting
Limited Partner’s offer to purchase the ROFO Units. 

  
 47 

 (ii) If the ROFO Seller accepts a ROFO Accepting Limited Partner’s offer,
the ROFO Accepting Limited Partner must purchase the ROFO Units in the manner, and subject to the terms and conditions, described in Section 4.11(d). If the ROFO Seller does not accept any offer from a ROFO Accepting Limited Partner or fails to
make such election within thirty (30) days after receiving the ROFO Offer Notice, or if there are no ROFO Accepting Limited Partners, then the ROFO Seller may, during the next one hundred twenty (120) days, transfer the ROFO Units to a third-party
transferee (i) at a purchase price not less than 105% of the highest offered ROFO Price and upon terms no more favorable to the proposed transferee than those specified in the ROFO Notice and (ii) subject to the applicable terms and restrictions of
this Agreement, including Section 4.8. 
 (iii) If more than one ROFO Accepting Limited Partner submits a ROFO Offer Notice
and the ROFO Seller decides to accept any of such ROFO Offer Notices, then the ROFO Seller shall be obligated to accept such ROFO Offer Notice containing the highest offered ROFO Price. If the highest offered ROFO Price is submitted by more than one
ROFO Accepting Limited Partner, each such ROFO Accepting Limited Partner shall be allocated a number of ROFO Units on a Pro Rata basis in accordance with the number of Common Units or Subordinated Units, as applicable, owned by such ROFO Accepting
Limited Partner in relation to the total number of Common Units or Subordinated Units, as applicable, owned by all ROFO Accepting Limited Partners, or in such other proportion as such ROFO Accepting Limited Partners shall otherwise agree. 

(c) The obligations in this Section 4.11 shall apply only to any proposed transfer of Common Units or Subordinated Units, or series of such
transfers to the same Person, by a Sponsor Party involving more than 5% of the aggregate of the Common Units and Subordinated Units held by such Sponsor Party. 

(d) Sales of the ROFO Units to the applicable ROFO Accepting Limited Partner pursuant to this Section 4.11 shall be made at the offices of the
Partnership within sixty (60) days of the delivery of ROFO Acceptance Notice, or on such other date as the participating parties may agree in writing. Such sales shall be effected by the ROFO Seller’s delivery of the ROFO Units, free and clear
of all Encumbrances (other than restrictions imposed by the governing documents of the Partnership and securities laws), to the applicable ROFO Accepting Limited Partner, against payment to the ROFO Seller of the ROFO Price by the applicable ROFO
Accepting Limited Partner and on the terms and conditions specified in the applicable ROFO Offer Notice. 
 Section 4.12 Sponsor Party
Right of First Refusal. 
 (a) Subject to Section 4.8 and Section 4.12(c), except for a Permitted Transfer or a transfer to which
Section 4.11 applies, if a Sponsor Party (a “ROFR Seller”) receives an unsolicited bona fide offer from a third party for a transfer of all or any portion of the ROFR Seller’s Common Units or Subordinated Units,
and the ROFR Seller wishes to accept such offer, 

  
 48 

 
the ROFR Seller shall first provide a written notice (the “ROFR Seller’s Notice”) to each other Sponsor Party (or, in the case of a transfer of
Subordinated Units, only to the other Sponsor Parties holding Subordinated Units), with a copy to the Partnership, containing: (i) the number of Common Units or Subordinated Units proposed to be transferred (the “ROFR Units”)
and the per Unit purchase price offered therefor, which may only be in cash (the “ROFR Sale Price”), and (ii) the material terms and conditions of such proposed transfer. Delivery of the ROFR Seller’s Notice to the
Sponsor Parties entitled to receive such notice (each, a “ROFR Non-Transferring Limited Partner”) shall constitute an offer (a “ROFR Offer”) by the ROFR Seller to sell the ROFR Units at the ROFR Sale
Price to each other ROFR Non-Transferring Limited Partner, which shall remain outstanding for a period of thirty (30) days after the delivery of the ROFR Seller’s Notice (subject to extension as provided below, the “ROFR
Period”). 
 (b) The following procedures shall apply: 

(i) During the ROFR Period, each ROFR Non-Transferring Limited Partner shall have the right to accept the ROFR Offer in full
but not in part, by delivering a written notice to the ROFR Seller (a “ROFR Acceptance Notice”), with a copy to each other ROFR Non-Transferring Limited Partner (if applicable) and the Partnership of its
acceptance of the ROFR Offer with respect to all of the ROFR Units at the ROFR Sale Price and on the same terms specified in the ROFR Seller’s Notice. 

(ii) If more than one ROFR Acceptance Notice is timely delivered to the ROFR Seller, each ROFR Non-Transferring Limited Partner
that submitted a ROFR Acceptance Notice shall be entitled to purchase a portion of the ROFR Units determined on a Pro Rata basis in accordance with the number of Common Units or Subordinated Units, as applicable, owned by each such participating
ROFR Non-Transferring Limited Partner in relation to the total number of Common Units or Subordinated Units, as applicable, owned by all such participating ROFR Non-Transferring Limited Partners, or in such other proportion as such ROFR
Non-Transferring Limited Partners may agree. 
 (iii) A failure by a ROFR Non-Transferring Limited Partner to validly deliver
a ROFR Acceptance Notice during the ROFR Period shall be deemed a rejection of the ROFR Offer and a waiver of such ROFR Non-Transferring Limited Partner’s right to purchase any portion of the ROFR Units. 

(iv) If no ROFR Non-Transferring Limited Partner timely delivers a ROFR Acceptance Notice, then the ROFR Seller shall be free,
for a period of one hundred twenty (120) days from the date of the expiration of the ROFR Period, to sell such ROFR Units to a third party (the “Proposed Transferee”) (x) at a price per Unit equal to or greater than the ROFR
Price and upon terms no more favorable to the Proposed Transferee than those specified in the ROFR Seller’s Notice and (y) subject to the applicable terms and restrictions of this Agreement, including Section 4.8. 

(c) The obligations in this Section 4.12 shall apply only to any proposed transfer of Common Units or Subordinated Units, or series of such
transfers to the same Person, by a Sponsor Party involving more than 5% of the aggregate of the Common Units or Subordinated Units held by such Sponsor Party. 

(d) Sales of the ROFR Units to be sold to the participating ROFR Non-Transferring Limited Partners pursuant to this Section 4.12 shall be made
at the offices of the Partnership within sixty (60) days of the delivery of ROFR Seller’s Notice, or on such other date as the participating parties may agree in writing. Such sales shall be effected by the ROFR Seller’s delivery of the
ROFR Units, free and clear of all Encumbrances (other than restrictions imposed by the governing documents of the Partnership and securities laws), to the participating ROFR Non-Transferring Limited Partners, against payment to the ROFR Seller of
the purchase consideration therefor by the participating ROFR Non-Transferring Limited Partners and on the terms and conditions specified in the ROFR Seller’s Notice.

 ARTICLE V 

CAPITAL CONTRIBUTIONS AND ISSUANCE OF PARTNERSHIP INTERESTS 

Section 5.1 Reserved. 

Section 5.2 Reserved. 

Section 5.3 Contributions by Limited Partners. No Limited Partner will be required to make any additional Capital Contribution to
the Partnership pursuant to this Agreement. 
 Section 5.4 Interest and Withdrawal. No interest shall be paid by the Partnership
on Capital Contributions. No Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent, if any, that distributions made pursuant to this Agreement or upon termination of the Partnership may be
considered as such by law and then only to the extent provided for in this Agreement. Except to the extent expressly provided in this Agreement, no Partner shall have priority over any other Partner either as to the return of Capital
Contributions or as to profits, losses or distributions. Any such return shall be a compromise to which all Partners agree within the meaning of Section 17-502(b) of the Delaware Act. 

Section 5.5 Capital Accounts. 

(a) The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee, agent or representative
in any case in which the nominee, agent or representative has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest
a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). 

  
 50 

 
As of the IPO Closing Date, the Capital Account balance attributable to the Common Units issued to the Organizational Limited Partner, OGEH, and Bronco equaled the product of the number of Common
Units issued to the Organizational Limited Partner, OGEH, and Bronco, respectively, and the Initial Unit Price for each such Common Unit (and the Capital Account balance attributable to each such Common Unit shall equal its Initial Unit Price). As
of the IPO Closing Date, the Capital Account attributable to the Incentive Distribution Rights was zero. The initial Capital Account of the initial holder of a Series A Preferred Unit with respect to such Series A Preferred Unit shall equal the
Stated Series A Liquidation Preference irrespective of the amount paid by such holder for such Series A Preferred Unit. The initial Capital Account of the initial holder of a Series B Preferred Unit with respect to such Series B Preferred Unit
shall equal the Capital Account balance of the Series A Preferred Unit subject to the Series A Non-Affiliate Conversion immediately prior to the Series B Conversion Date, irrespective of the amount paid by such holder for such Series B Preferred
Unit. 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
made with respect to such Partnership Interest except for non-liquidating distributions with respect to a Series A Preferred Unit or a Series B Preferred Unit 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. In connection with the foregoing, the General Partner shall adopt the methodology set forth in the noncompensatory option regulations under Treasury
Regulation Sections 1.704-1, 1.721-2 and 1.761-3, unless otherwise required by applicable law. 
 (b) For purposes of computing the amount
of any item of income, gain, loss or deduction that is to be allocated pursuant to Article VI and is to be reflected in the Partners’ Capital Accounts, the determination, recognition and classification of any such item shall be the same as its
determination, recognition and classification for federal income tax purposes (including any method of depreciation, cost recovery or amortization used for that purpose), provided, that: 

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

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

  
 51 

 (iii) The computation of all items of income, gain, loss and deduction shall be
made (x) except as otherwise provided in Treasury Regulation Section 1.704-1(b)(2)(iv)(m), without regard to any election under Section 754 of the Code that may be made by the Partnership and (y) 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. 

(iv) To the extent an adjustment to the adjusted basis of any Partnership asset pursuant to Section 734(b) of the Code
(including pursuant to Treasury Regulation Section 1.734-2(b)(1)) 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. 
 (v) In the event the Carrying Value of Partnership property is
adjusted pursuant to Section 5.5(d), any Unrealized Gain resulting from such adjustment shall be treated as an item of gain and any Unrealized Loss resulting from such adjustment shall be treated as an item of loss. 

(vi) 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. 

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

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

(c) 
 (i) Except
as otherwise provided in this Section 5.5(c), a transferee of a Partnership Interest shall succeed to a Pro Rata portion of the Capital Account of the transferor relating to the Partnership Interest so transferred. 

  
 52 

 (ii) Subject to Section 6.7(c), immediately prior to the transfer of a
Subordinated Unit or of a Subordinated Unit that has converted into a Common Unit pursuant to Section 5.7 by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.5(c)(ii) apply), the
Capital Account maintained for such Person with respect to its Subordinated Units or converted Subordinated Units will (A) first, be allocated to the Subordinated Units or converted Subordinated Units to be transferred in an amount equal to the
product of (x) the number of such Subordinated Units or converted Subordinated Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be retained by the
transferor, regardless of whether it has retained any converted Subordinated Units (“Retained Converted Subordinated Units”) or Subordinated Units. Following any such allocation, the transferor’s Capital Account, if any,
maintained with respect to the retained Subordinated Units or Retained Converted Subordinated Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with
respect to the transferred Subordinated Units or transferred converted Subordinated Units will have a balance equal to the amount allocated under clause (A) hereinabove. 

(iii) Subject to Section 6.8(b), immediately prior to the transfer of an IDR Reset Common Unit by a holder thereof (other than
a transfer to an Affiliate unless the General Partner elects to have this subparagraph (iii) apply), the Capital Account maintained for such Person with respect to its IDR Reset Common Units will (A) first, be allocated to the IDR Reset Common Units
to be transferred in an amount equal to the product of (x) the number of such IDR Reset Common Units to be transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B) second, any remaining balance in such Capital Account will be
retained by the transferor, regardless of whether it has retained any IDR Reset Common Units. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained IDR Reset Common Units, if any, will
have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred IDR Reset Common Units will have a balance equal to the amount allocated under clause
(A) above. 
 (d) 

(i) In accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(f) and (s), on an issuance of additional Partnership
Interests for cash or Contributed Property, the issuance of Partnership Interests as consideration for the provision of services, the issuance of IDR Reset Common Units pursuant to Section 5.11, exercise or conversion of a Noncompensatory Option
(including the Series A Non-Affiliate Conversion in accordance with Section 16.12(a), the conversion of a Series A Preferred Unit in accordance with Section 16.4 and the conversion of a Series B Preferred Unit in accordance with Section 17.4) or the
conversion of the General Partner’s Combined Interest to Common Units pursuant to Section 11.3(b), the Capital Account of each Partner and the Carrying Value of each Partnership property immediately prior to such issuance, or immediately after
such exercise or conversion, shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such 

  
 53 

 
Partnership property; provided, however, that in the event of an issuance of Partnership Interests for a de minimis amount of cash or Contributed Property, the issuance of a
Noncompensatory Option to acquire a de minimis Partnership Interest, or 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. Any such Unrealized Gain or Unrealized Loss (or items thereof) shall first be allocated to the Partners holding Conversion Common Units until the Capital Account of each
Conversion Common Unit is equal to the Per Unit Capital Amount for a then Outstanding Common Unit (other than a Conversion Common Unit) if the operation of this sentence is triggered by the conversion of a Series A Preferred Unit or a Series B
Preferred Unit, and regardless of whether the operation of this sentence is triggered by the conversion of a Series A Preferred Unit or a Series B Preferred Unit any remaining Unrealized Gain or Unrealized Loss shall be allocated among the Partners
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. If upon the occurrence of a
Revaluation Event described in this Section 5.5(d), a Noncompensatory Option of the Partnership is outstanding, the Partnership shall adjust the Carrying Value of each Partnership property in accordance with Treasury Regulation Sections
1.704-1(b)(2)(iv)(f)(1) and 1.704-1(b)(2)(iv)(h)(2). In determining Unrealized Gain or Unrealized Loss, the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to the issuance of additional
Partnership Interests (or, in the case of an issuance of a Noncompensatory Option, immediately after such issuance if required pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(1)) shall be determined by the General Partner using such
method of valuation as it may adopt. In making its determination of the fair market values of individual properties, the General Partner may first determine an aggregate value for the assets of the Partnership that takes into account the current
trading price of the Common Units, the fair market value of all other Partnership Interests at such time and the amount of Partnership Liabilities, and the General Partner must reduce the fair market value of all Partnership assets by the excess, if
any, of the fair market value of any Outstanding Series A Preferred Units and Outstanding Series B Preferred Units that have not yet been converted over the aggregate Stated Series A Liquidation Preference and Stated Series B Liquidation Preference
of such Series A Preferred Units and Series B Preferred Units, respectively, to the extent of any Unrealized Gain that has not been reflected in the Partners’ Capital Accounts previously, pursuant to Treasury Regulation Section
1.704-1(b)(2)(iv)(h)(2). The General Partner may allocate such aggregate value among the individual properties of the Partnership (in such manner as it determines appropriate). Absent a contrary determination by the General Partner, the aggregate
fair market value of all Partnership assets (including, without limitation, cash or cash equivalents) immediately prior to a Revaluation Event shall be the value that would result in the Capital Account for each Common Unit that is Outstanding prior
to such Revaluation Event being equal to the Event Issue Value. 
 (ii) In accordance with Treasury Regulation Section
1.704-1(b)(2)(iv)(f), immediately prior to any 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

  
 54 

 
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. In determining such Unrealized Gain or Unrealized Loss the aggregate fair market value of all Partnership property (including cash or cash equivalents) immediately prior to a distribution shall (A) in the case of a
distribution that is not made pursuant to Section 12.4, be determined in the same manner as that provided in Section 5.5(d)(i) or (B) in the case of a liquidating distribution pursuant to Section 12.4, be determined by the Liquidator using such
method of valuation as it may adopt. 
 Section 5.6 Issuances of Additional Partnership Interests; Derivative Partnership
Interests. 
 (a) Subject to any approvals required by Series A Holders pursuant to Section 16.5(b)(ii) and Series B Holders pursuant to
Section 17.5(b)(ii), the Partnership may issue additional Partnership Interests (other than General Partner Interests) and Derivative Partnership Interests for any Partnership purpose at any time and from time to time to such Persons for such
consideration and on such terms and conditions as the General Partner shall determine, all without the approval of any Limited Partners. 

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

(c) The General Partner shall take all actions that it determines to be necessary or appropriate in connection with (i) each issuance of
Partnership Interests and Derivative Partnership Interests pursuant to this Section 5.6, (ii) the conversion of the Combined Interest into Units pursuant to the terms of this Agreement, (iii) the issuance of Common Units pursuant to Section
5.11, (iv) reflecting admission of such additional Limited Partners in the Register as the Record Holders of such Limited Partner Interests 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 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 in connection with the conversion of the Combined Interest into Units pursuant to the terms of this Agreement, including compliance
with any statute, rule, 

  
 55 

 
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 convert into Common Units on a one-for-one basis on the expiration of the Subordination Period. 

(b) In the event that Subordinated Units shall convert into Common Units pursuant to Section 5.7(a) at a time when there shall be more than
one holder of Subordinated Units, then, unless all of the holders of the Subordinated Units shall agree to a different allocation, the Subordinated Units that are to be converted into Common Units shall be allocated among the holders of the
Subordinated Units pro rata based on the number of Subordinated Units held by each such holder. 
 (c) A Subordinated Unit that has
converted into a Common Unit shall be subject to the provisions of Section 6.7. 
 Section 5.8 Limited Preemptive Right. Except
as provided in this Section 5.8 and Section 5.11 or as otherwise provided in a separate agreement by the Partnership, no Person shall have any preemptive, preferential or other similar right with respect to the issuance of any Partnership Interest,
whether unissued, held in the treasury or hereafter created. For so long as a Person remains an Affiliate of the General Partner, each Affiliate of the General Partner shall have the right, which it may from time to time assign in whole or in
part to any of its Affiliates, to purchase Partnership Interests from the Partnership whenever, and on the same terms that, the Partnership issues Partnership Interests to Persons other than the General Partner and its Affiliates, up to the extent
necessary to maintain the Percentage Interests of such Person equal to that which existed immediately prior to the issuance of such Partnership Interests. 

Section 5.9 Splits and Combinations. 

(a) Subject to Section 5.9(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 of any class or series to all Record Holders of Partnership Interests of such class or series of Partnership Interests or may effect a subdivision or combination of the same class or series of Partnership
Interests so long as, after any such event, each Partner holding such class of Partnership Interests shall have the same Percentage Interest in the Partnership as before such event (subject to the effect of Section 5.9(d)), and any amounts
calculated on a per Unit basis (including those based on the Series A Liquidation Preference, the Series B Liquidation Preference and any Common Unit Arrearage or Cumulative Common Unit Arrearage) or stated as a number of Units are proportionately
adjusted. 

  
 56 

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

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

(d) The Partnership shall not issue fractional Units upon any distribution, subdivision, combination or conversion of Units. If a
distribution, subdivision, combination or conversion of Units would result in the issuance of fractional Units but for the provisions of Section 5.6(d) and this Section 5.9(d), each fractional Unit shall be rounded to the nearest whole Unit (with
fractional Units equal to or greater than a 0.5 Unit being rounded to the next higher 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, Article XVI and Article XVII shall be fully paid and non-assessable Limited
Partner Interests in the Partnership, except as such non-assessability may be affected by Sections 17-303, 17-607 or 17-804 of the Delaware Act. 

Section 5.11 Issuance of Common Units in Connection with Reset of Incentive Distribution Rights. 

(a) Subject to the provisions of this Section 5.11, the holder of the Incentive Distribution Rights (or, if there is more than one holder of
the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall have the right, at any time when there are no Subordinated Units outstanding and the Partnership has made a distribution pursuant to
Section 6.4(b)(v) for each of the four most recently completed Quarters and the amount of each such distribution did not exceed Adjusted Operating Surplus for such Quarter, to make an election (the “IDR Reset Election”) to
cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights

  
 57 

 
will become entitled to receive their respective proportionate share of a number of Common Units (the “IDR Reset Common Units”) derived by dividing (i) the average amount
of 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 making of the IDR Reset Election in the manner specified in this
Section 5.11 shall cause the Minimum Quarterly Distribution and the Target Distributions to be reset in accordance with the provisions of Section 5.11(e) and, in connection therewith, the holder or holders of the Incentive Distribution Rights will
become entitled to receive IDR Reset Common Units on the basis specified above, without any further approval required by the Unitholders other than as set forth in this Section 5.11(a), at the time specified in Section 5.11(c) unless the IDR Reset
Election is rescinded pursuant to Section 5.11(d). 
 (b) To exercise the right specified in Section 5.11(a), the holder of the Incentive
Distribution Rights (or, if there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights) shall deliver a written notice (the “Reset Notice”)
to the Partnership. Within 10 Business Days after the receipt by the Partnership of such Reset Notice, the Partnership shall deliver a written notice to the holder or holders of the Incentive Distribution Rights of the Partnership’s
determination of the Aggregate Quantity of IDR Reset Common Units that each holder of Incentive Distribution Rights will be entitled to receive. 

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

  
 58 

 
Units would have had at the time of the Partnership’s receipt of the Reset Notice, as determined by the General Partner, and (ii) for the subsequent conversion of such Partnership Interests
into Common Units within not more than 12 months following the Partnership’s receipt of the Reset Notice upon the satisfaction of one or more conditions that are reasonably acceptable to the holder of the Incentive Distribution Rights (or, if
there is more than one holder of the Incentive Distribution Rights, the holders of a majority in interest of the Incentive Distribution Rights). 

(e) The Minimum Quarterly Distribution and the Target Distributions, shall be adjusted at the time of the issuance of IDR Reset Common Units
or other Partnership Interests pursuant to this Section 5.11 such that (i) the Minimum Quarterly Distribution shall be reset to equal the average cash distribution amount per Common Unit for the two Quarters immediately prior to the
Partnership’s receipt of the Reset Notice (the “Reset MQD”), (ii) the First Target Distribution shall be reset to equal 115% of the Reset MQD, (iii) the Second Target Distribution shall be reset to equal 125% of the
Reset MQD and (iv) the Third Target Distribution shall be reset to equal 150% of the Reset MQD. 
 (f) Upon the issuance of IDR Reset Common
Units pursuant to Section 5.11(a), the Capital Account maintained with respect to the Incentive Distribution Rights will (i) first, be allocated to IDR Reset Common Units in an amount equal to the product of (A) the Aggregate Quantity of IDR Reset
Common Units and (B) the Per Unit Capital Amount for an IPO Common Unit, and (ii) second, as to any remaining balance in such Capital Account, will be retained by the holder of the Incentive Distribution Rights. If there is not sufficient capital
associated with the Incentive Distribution Rights to allocate the full Per Unit Capital Amount for an IPO Common Unit to the IDR Reset Common Units in accordance with clause (i) of this Section 5.11(f), the IDR Reset Common Units shall be subject to
Sections 6.1(d)(xi)(B) and (C). 
 ARTICLE VI 

ALLOCATIONS AND DISTRIBUTIONS 

Section 6.1 Allocations for Capital Account Purposes. For purposes of maintaining the Capital Accounts and in determining the rights of
the Partners among themselves, the Partnership’s items of income, gain, loss and deduction (computed in accordance with Section 5.5(b)) for each taxable period (other than any taxable period (or portion thereof) ending on or prior to the IPO
Closing Date, with respect to which the First Amended and Restated Agreement of Limited Partnership of Enable Midstream Partners, LP shall govern) shall be allocated among the Partners as provided herein below. 

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

(i) First, to the General Partner until the aggregate amount of Net Income allocated to the General Partner pursuant to this
Section 6.1(a)(i) for the current and all previous taxable periods is equal to the aggregate amount of Net Loss allocated to the General Partner pursuant to Section 6.1(b)(iii) for all previous taxable periods; 

  
 59 

 (ii) Second, to all Partners holding Preferred Units, in proportion to their
positive Adjusted Capital Account balances, until the aggregate amount of Net Income allocated to such Partners pursuant to this Section 6.1(a)(ii) for the current and all previous taxable periods is equal to the aggregate amount of Net Loss
allocated to such Partners pursuant to Section 6.1(b)(ii) for all previous taxable periods; provided that in no event shall Net Income be allocated to such Partner to cause its Capital Account to exceed the Stated Series A Liquidation Preference or
Stated Series B Liquidation Preference, as applicable; and 
 (iii) The balance, if any, to all Unitholders, Pro Rata. 

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

(i) First, to the Unitholders, Pro Rata; provided, that Net Losses shall not be allocated pursuant to this Section
6.1(b)(i) to the extent that 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 balance in its Adjusted Capital Account); 

(ii) Second, to all Partners holding Preferred Units, in proportion to their positive Adjusted Capital Account balances, until
the Adjusted Capital Account balance with respect to each Preferred Unit then Outstanding has been reduced to zero; and 

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

(c) Net Termination Gains and Losses. After giving effect to the special allocations set forth in Section 6.1(d), Net Termination
Gain or Net Termination Loss (including a pro rata part of each item of income, gain, loss and deduction taken into account in computing Net Termination Gain or Net Termination Loss) for such taxable period shall be allocated in the manner set forth
in this Section 6.1(c). All allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 6.1 and after all distributions of Available Cash provided
under Section 6.4, Section 6.5, Section 16.3 and Section 17.3 have been made; provided, however, that solely for purposes of this Section 6.1(c), Capital Accounts shall not be adjusted for distributions made pursuant to Section 12.4. 

(i) Except as provided in Section 6.1(c)(iv), and subject to the provisions set forth in the last sentence of this Section
6.1(c)(i), Net Termination Gain (including a pro rata part of each item of income, gain, loss, and deduction taken into account in computing Net Termination Gain) shall be allocated in the following order and priority: 

(A) First, to each Partner having a deficit balance in its Adjusted Capital Account, in the proportion that such deficit
balance bears to the total 

  
 60 

 
deficit balances in the Adjusted Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Adjusted Capital
Account; 
 (B) Second, to all Unitholders holding Common Units, 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 Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to Section 6.4(a)(i) or
Section 6.4(b)(i) with respect to such Common Unit for such Quarter (the amount determined pursuant to this clause (2) is hereinafter referred to as the “Unpaid MQD”) and (3) any then existing Cumulative Common Unit
Arrearage; 
 (C) Third, if such Net Termination Gain is recognized (or is deemed to be recognized) prior to the conversion
of the last Outstanding Subordinated Unit into a Common Unit, to all Unitholders holding Subordinated Units, Pro Rata, until the Capital Account in respect of each Subordinated Unit then Outstanding equals the sum of (1) its Unrecovered Initial Unit
Price, determined for the taxable period (or portion thereof) to which this allocation of gain relates, and (2) the Minimum Quarterly Distribution for the Quarter during which the Liquidation Date occurs, reduced by any distribution pursuant to
Section 6.4(a)(iii) with respect to such Subordinated Unit for such Quarter; 
 (D) Fourth, to 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 after the Closing Date or the date of the most recent IDR Reset Election, if any, 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(a)(iv) and Section 6.4(b)(ii) for such period (the sum of (1), (2), (3) and (4) is hereinafter referred to as the “First Liquidation Target Amount”); 

(E) Fifth, (x) 15% to the holders of the Incentive Distribution Rights, Pro Rata, and (y) 85% to all Unitholders, Pro Rata,
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 Distribution for each Quarter
after the Closing Date or the date of the most recent IDR Reset Election, if any, 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(a)(v) and Section
6.4(b)(iii) for such period (the sum of (1) and (2) is hereinafter referred to as the “Second Liquidation Target Amount”); 

(F) Sixth, (x) 25% to the holders of the Incentive Distribution Rights, Pro Rata, and (y) 75% to all Unitholders, Pro Rata,
until the Capital Account in 

  
 61 

 
respect of each Common Unit then Outstanding is equal to the sum of (1) the Second Liquidation Target Amount, and (2) the excess of (aa) the Third Target Distribution less the Second Target
Distribution for each Quarter after the Closing Date or the date of the most recent IDR Reset Election, if any, 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(a)(vi) and Section 6.4(b)(iv) for such period; and 
 (G) Finally, (x) 50% to the holders of the Incentive
Distribution Rights, Pro Rata, and (y) 50% to all Unitholders, Pro Rata. 
 Notwithstanding the foregoing provisions in this Section 6.1(c)(i), the General
Partner may adjust the amount of any Net Termination Gain arising in connection with a Revaluation Event that is allocated to the holders of Incentive Distribution Rights in a manner that will result (i) in the Capital Account for each Common Unit
that is Outstanding prior to such Revaluation Event being equal to the Event Issue Value and (ii) to the greatest extent possible, the Capital Account with respect to the Incentive Distribution Rights that are Outstanding prior to such Revaluation
Event being equal to the amount of Net Termination Gain that would be allocated to the holders of the Incentive Distribution Rights pursuant to this Section 6.1(c)(i) if the Capital Accounts with respect to all Partnership Interests that were
Outstanding immediately prior to such Revaluation Event and the Carrying Value of each Partnership property were equal to zero. 

(ii) Except as otherwise provided by Section 6.1(c)(iii) or Section 6.1(c)(iv), Net Termination Loss (including a pro 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, to all Unitholders holding Subordinated Units, Pro Rata, until the
Adjusted Capital Account in respect of each Subordinated Unit then Outstanding has been reduced to zero; 
 (B) Second, to
all Unitholders holding Common Units, Pro Rata, until the Adjusted Capital Account in respect of each Common Unit then Outstanding has been reduced to zero; 

(C) Third, to all Partners holding Preferred Units, in proportion to their Adjusted Capital Account balances, until the
Adjusted Capital Account in respect of each Preferred Unit has been reduced to zero; and 
 (D) The balance, if any, 100% to
the General Partner. 
 (iii) Net Termination Loss deemed recognized pursuant to clause (b) of the definition of Net
Termination Loss as a result of a Revaluation Event prior to the conversion of the last Outstanding Subordinated Unit and prior to the Liquidation Date shall be allocated: 

(A) First, to the Unitholders, Pro Rata, until the Capital Account in respect of each Common Unit then Outstanding equals the
Event Issue Value; provided that Net Termination Loss shall not be allocated pursuant to this Section 6.1(c)(iii)(A) 

  
 62 

 
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); 
 (B) Second, to all Unitholders holding Subordinated Units, Pro Rata; provided, however,
that Net Termination Loss shall not be allocated pursuant to this Section 6.1(c)(iii)(B) 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); 
 (C) Third, to all Partners holding Preferred Units, in
proportion to their Adjusted Capital Account balances, until the Adjusted Capital Account in respect of each Preferred Unit has been reduced to zero; and 

(D) The balance, if any, to the General Partner. 

(iv) If (A) a Net Termination Loss has been allocated pursuant to Section 6.1(c)(iii), (B) a Net Termination Gain or Net
Termination Loss subsequently occurs (other than as a result of a Revaluation Event) prior to the conversion of the last Outstanding Subordinated Unit and (C) after tentatively making all allocations of such Net Termination Gain or Net Termination
Loss provided for in Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable, the Capital Account in respect of each Common Unit does not equal the amount such Capital Account would have been if Section 6.1(c)(iii) had not been part of this Agreement
and 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, then items of income, gain, loss and deduction included in such Net Termination Gain or Net
Termination Loss, as applicable, shall be specially allocated to the General Partner and all Unitholders in a manner that will, to the maximum extent possible, cause the Capital Account in respect of each Common Unit to equal the amount such Capital
Account would have been if all 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. 

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

  
 63 

 
Section 6.1(d)(i) is intended to comply with the Partnership Minimum Gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith. 

(ii) Chargeback of Partner Nonrecourse Debt Minimum Gain. Notwithstanding the other provisions of this Section 6.1 (other than
Section 6.1(d)(i)), except as provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse Debt Minimum Gain during any Partnership taxable period, any Partner with
a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such taxable period shall be allocated items of Partnership income and gain for such period (and, if necessary, subsequent periods) in the manner and amounts provided in Treasury
Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2)(ii), or any successor provisions. For purposes of this Section 6.1(d), each Partner’s Adjusted Capital
Account balance shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Section 6.1(d), 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 with respect to a taxable period exceeds the amount of cash or the Net Agreed Value of property distributed with respect to another Unit with respect to the same taxable period (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 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. 
 (B) After the application of
Section 6.1(d)(iii)(A), all or any portion of the remaining items of Partnership gross income or gain for the taxable period, if any, shall be allocated to the holders of Incentive Distribution Rights, Pro Rata, until the aggregate amount of such
items allocated to the holders of Incentive Distribution Rights pursuant to this Section 6.1(d)(iii)(B) for the current taxable period and all previous taxable periods is equal to the cumulative amount of all Incentive Distributions made to the
holders of Incentive Distribution Rights from the IPO Closing Date to a date 45 days after the end of the current taxable period. 

(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), 

  
 64 

 
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 Allocation. In the event any Partner has a deficit balance in its Capital Account at the end of any taxable
period in excess of the sum of (A) the amount such Partner is required to restore pursuant to the provisions of this Agreement and (B) the amount such Partner is deemed obligated to restore pursuant to Treasury Regulation Sections 1.704-2(g) and
1.704-2(i)(5), such Partner shall be specially allocated items of Partnership gross income and gain in the amount of such excess as quickly as possible; provided, 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. 

(ix) Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to
Section 734(b) of the Code 

  
 65 

 
(including pursuant to Treasury Regulation section 1.734-2(b)(1)) 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) Preferred Unit Allocations. 

(A) Income of the Partnership attributable to the issuance by the Partnership of a Series A Preferred Unit or Series B
Preferred Unit for an amount in excess of such Series A Preferred Unit’s Stated Series A Liquidation Preference or Series B Preferred Unit’s Stated Series B Liquidation Preference shall be allocated to all Unitholders and the General
Partner in accordance with their respective Percentage Interests. 
 (B) To the extent Net Termination Losses were allocated
to Partners holding Preferred Units pursuant to Section 6.1(c)(ii) or (iii) in any previous taxable period, such Partners shall be allocated Net Termination Gain (or, to the extent necessary, items of income or gain for the taxable period) in
proportion to, and to the extent of, an amount equal to the excess, if any, of (1) the Stated Series A Liquidation Preference or Stated Series B Liquidation Preference (as applicable) with respect to such holder’s Preferred Units, over (2) such
holder’s existing Capital Account balance in respect of such Series A Preferred Units or Series B Preferred Units, until the Capital Account balance of each such Partner in respect of its Series A Preferred Units or Series B Preferred Units is
equal to the Stated Series A Liquidation Preference or Stated Series B Liquidation Preference (as applicable) with respect to such Partners’ Series A Preferred Units or Series B Preferred Units, respectively. 

(xi) 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 

  
 66 

 
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)(xi)(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. 

(C) With respect to any taxable period during which an IDR Reset 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 Unit to an amount equal to the Per Unit Capital Amount 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)(xi)(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. 

  
 67 

 (xii) Curative Allocation. 

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

(B) The General Partner shall, with respect to each taxable period, (1) apply the provisions of Section 6.1(d)(xii)(A) in
whatever order is most likely to minimize the economic distortions that might otherwise result from the Required Allocations, and (2) divide all allocations pursuant to Section 6.1(d)(xii)(A) among the Partners in a manner that is likely to minimize
such economic distortions. 
 (xiii) Equalization of Capital Accounts With Respect to Privately Placed Units. Net Termination
Gain or Net Termination Loss deemed recognized as a result of a Revaluation Event shall first be allocated to the (A) Unitholders holding Privately Placed Units or (B) Unitholders holding Common Units, Pro Rata, as applicable, to the
extent necessary to cause the Capital Account in respect of each Privately Placed Unit then Outstanding to equal the Capital Account in respect of each Common Unit (other than Privately Placed Units) then Outstanding. 

  
 68 

 (xiv) Corrective and Other Allocations. In the event of any allocation of
Additional Book Basis Derivative Items or a Net Termination Loss, the following rules shall apply: 
 (A) The General Partner
shall allocate Additional Book Basis Derivative Items consisting of depreciation, amortization, depletion or any other form of cost recovery (other than Additional Book Basis Derivative Items included in Net Termination Gain or Net Termination Loss)
with respect to any Adjusted Property to the Unitholders, Pro Rata, and the holders of Incentive Distribution Rights, all in the same proportion as the Net Termination Gain or Net Termination Loss resulting from the Revaluation Event that gave rise
to such Additional Book Basis Derivative Items was allocated to them pursuant to Section 6.1(c). 
 (B) If a sale or other
taxable disposition of an Adjusted Property, including, for this purpose, inventory (“Disposed of Adjusted Property”) occurs other than in connection with an event giving rise to Net Termination Gain or Net Termination Loss,
the General Partner shall allocate (1) items of gross income and gain (aa) away from the holders of Incentive Distribution Rights and (bb) to the Unitholders, or (2) 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 with respect to the Disposed of Adjusted Property (determined in accordance with the last sentence of the definition of Additional Book Basis Derivative
Items) treated as having been allocated to the Unitholders pursuant to this Section 6.1(d)(xiv)(B) exceed their Share of Additional Book Basis Derivative Items with respect to such Disposed of Adjusted Property. For purposes of this Section
6.1(d)(xiv)(B), the Unitholders shall be treated as having been 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 (e.g., Additional Book Basis Derivative Items taken into account in computing cost of goods sold would reduce the amount of book income otherwise available for allocation among the
Partners). Any allocation made pursuant to this Section 6.1(d)(xiv)(B) shall be made after all of the other Agreed Allocations have been made as if this Section 6.1(d)(xiv) were not in this Agreement and, to the extent necessary, shall require
the reallocation of items that have been allocated pursuant to such other Agreed Allocations. 
 (C) Net Termination Loss in
an amount equal to the lesser of (1) such Net Termination Loss and (2) the Aggregate Remaining Net Positive Adjustments shall be allocated in such a manner, as determined by the General Partner, that to the extent possible, the Capital Account
balances of the Partners will equal the amount they would have been had no prior Book-Up Events occurred, and any remaining Net Termination Loss shall be allocated pursuant to Section 6.1(c) hereof. In
allocating Net Termination Loss pursuant to this Section 6.1(d)(xiv)(C), the General Partner shall attempt, to the extent possible, to cause the Capital Accounts of the Unitholders, on the one hand, and holders of the Incentive Distribution Rights,
on the other hand, to equal the amount they would equal if (i) the Carrying Values of the Partnership’s property had not been previously adjusted in connection with any prior Book-Up Events, (ii) Unrealized Gain and Unrealized Loss
(or, in the case of a liquidation, actual gain or loss) 

  
 69 

 
with respect to such Partnership Property were determined with respect to such unadjusted Carrying Values, and (iii) any resulting Net Termination Gain had been allocated pursuant to Section
6.1(c)(i) (including, for the avoidance of doubt, taking into account the provisions set forth in the last sentence of Section 6.1(c)(i)). 

(D) For purposes of this Section 6.1(d)(xiv), the Unitholders shall be treated as being allocated Additional Book Basis
Derivative Items to the extent that such Additional Book Basis Derivative Items have reduced the amount of income that would otherwise have been allocated to the Unitholders under this Agreement. In making the allocations required under this Section
6.1(d)(xiv), the General Partner may apply whatever conventions or other methodology it determines will satisfy the purpose of this Section 6.1(d)(xiv). 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 Section 6.1(d)(xiv)(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)(xiv). 
 (E) Notwithstanding any other provision of this Section
6.1(d)(xiv), the determinations of Additional Book Basis (and items derived therefrom) and Net Positive Adjustments (and items derived therefrom) shall be made without regard to any Book-Up Event or Book-Down Event that occurred on or prior to the
IPO Closing Date. 
 (xv) Special Curative Allocation in Event of Liquidation Prior to Conversion of the Last Outstanding
Subordinated Unit. Notwithstanding any other provision of this Section 6.1 (other than the Required Allocations), if (A) the Liquidation Date occurs prior to the conversion of the last Outstanding Subordinated Unit and (B) after having made all
other allocations provided for in this Section 6.1 for the taxable period in which the Liquidation Date occurs, the Capital Account in respect of each Common Unit does not equal the amount such Capital Account would have been if Section 6.1(c)(iii)
and Section 6.1(c)(iv) had not been part of this Agreement and 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, then items of income, gain, loss
and deduction for such taxable period shall be reallocated among the General Partner and all Unitholders in a 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. For the avoidance
of doubt, the reallocation of items set forth in the immediately preceding sentence provides that, to the extent necessary to achieve the Capital Account balances described above, (x) items of income and gain that would otherwise be included in Net
Income or Net Loss, as the case may be, for the taxable 

  
 70 

 
period in which the Liquidation Date occurs, shall be reallocated from the Unitholders holding Subordinated Units to Unitholders holding Common Units and (y) items of deduction and loss that
would otherwise be included in Net Income or Net Loss, as the case may be, for the taxable period in which the Liquidation Date occurs shall be reallocated from Unitholders holding Common Units to the Unitholders holding Subordinated Units. In the
event that (i) the Liquidation Date occurs on or before the date (not including any extension of time prescribed by law for the filing of the Partnership’s federal income tax return for the taxable period immediately prior to the taxable period
in which the Liquidation Date occurs and (ii) the reallocation of items for the taxable period in which the Liquidation Date occurs as set forth above in this Section 6.1(d)(xv) fails to achieve the Capital Account balances described above, items of
income, gain, loss and deduction that would otherwise be included in the Net Income or Net Loss, as the case may be, for such prior taxable period shall be reallocated among all Unitholders in a manner that will, to the maximum extent possible and
after taking into account all other allocations made pursuant to this Section 6.1(d)(xv), cause the Capital Account in respect of each Common Unit to equal the amount such Capital Account would have been if all prior allocations of Net Termination
Gain and Net Termination Loss had been made pursuant to Section 6.1(c)(i) or Section 6.1(c)(ii), as applicable. 
 Section 6.2
Allocations for Tax Purposes. 
 (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)(xi)(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 

  
 71 

 
method, the General Partner may use any other depreciation and amortization conventions to preserve the uniformity of the intrinsic tax characteristics of any Limited Partner Interests, so long
as such conventions would not have a material adverse effect on the Limited Partners or the Record Holders of any class or classes of Limited Partner Interests. 

(d) In accordance with Treasury Regulation Sections 1.1245-1(e) and 1.1250-1(f), any gain allocated to the Partners upon the sale or other
taxable disposition of any Partnership asset shall, to the extent possible, after taking into account other required allocations of gain pursuant to this Section 6.2, be characterized as Recapture Income in the same proportions and to the same
extent as such Partners (or their predecessors in interest) have been allocated any deductions directly or indirectly giving rise to the treatment of such gains as Recapture Income. 

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

(f) Each item of Partnership income, gain, loss and deduction shall, for federal income tax purposes, 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 first Business Day of each month; provided, however, that gain or loss on a sale or other disposition of any assets of the Partnership or any
other extraordinary item of income, gain, loss or deduction as determined by the General Partner, shall be allocated to the Partners as of the opening of the first Business Day of the month in which such item is recognized for federal income tax
purposes. The General Partner may revise, alter or otherwise modify such methods of allocation to the extent permitted or required by Section 706 of the Code and the regulations or rulings promulgated thereunder. 

(g) Allocations that would otherwise be made to a Limited Partner under the provisions of this Article VI shall instead be made to the
beneficial owner of Limited Partner Interests held by a nominee, agent or representative in any case in which the nominee, agent or representative has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the
Code or any other method determined by the General Partner. 
 (h) If, as a result of an exercise of a Noncompensatory Option, a Capital
Account reallocation is required under Treasury Regulation Section 1.704-1(b)(2)(iv)(s)(3), the General Partner shall make corrective allocations pursuant to Treasury Regulation Section 1.704-1(b)(4)(x). 
 Section 6.3 Requirement and Characterization of Distributions; Distributions to
Record Holders. 
 (a) Subject to Section 16.3 and Section 17.3, 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 

  
 72 

 
Date selected by the General Partner. All amounts of Available Cash distributed by the Partnership on any date from any source shall be deemed to be Operating Surplus until the sum of all
amounts of Available Cash theretofore distributed by the Partnership to the Partners pursuant to Section 6.4 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.” All distributions required to be made under this Agreement shall be made
subject to Sections 17-607 and 17-804 of the Delaware Act. 
 (b) Notwithstanding Section 6.3(a) (but subject to the last sentence of
Section 6.3(a)), in the event of the dissolution and liquidation of the Partnership, all cash received during or after the Quarter in which the Liquidation Date occurs shall be applied and distributed solely in accordance with, and subject to the
terms and conditions of, Section 12.4. 
 (c) The General Partner may treat taxes paid by the Partnership on behalf of, or amounts withheld
with respect to, all or less than all of the Partners, as a distribution of Available Cash to such Partners, as determined appropriate under the circumstances by the General Partner. 

(d) Each distribution in respect of a Partnership Interest shall be paid by the Partnership, directly or through the Transfer Agent or through
any other Person or agent, only to the Record Holder of such Partnership Interest as of the Record Date set for such distribution. Such payment shall constitute full payment and satisfaction of the Partnership’s liability in respect of such
payment, regardless of any claim of any Person who may have an interest in such payment by reason of an assignment or otherwise. 
 Section
6.4 Distributions of Available Cash from Operating Surplus. 
 (a) During the Subordination Period. Subject to Section
16.3(b) and Section 17.3(b), Available Cash with respect to any Quarter within the Subordination Period that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or 6.5 shall be distributed as follows, except as otherwise
required in respect of additional Partnership Interests issued pursuant to Section 5.6(b): 
 (i) First, to the Unitholders
holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter; 

(ii) Second, to the Unitholders holding Common Units, Pro Rata, until there has been distributed in respect of each Common Unit
then Outstanding an amount equal to the Cumulative Common Unit Arrearage existing with respect to such Quarter; 
 (iii)
Third, to the Unitholders holding Subordinated Units, Pro Rata, until there has been distributed in respect of each Subordinated Unit then Outstanding an amount equal to the Minimum Quarterly Distribution for such Quarter; 

  
 73 

 (iv) Fourth, to all Unitholders, Pro Rata, until there has been distributed in
respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter; 

(v) Fifth, (A) 15% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 85% to all Unitholders, Pro Rata,
until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter; 

(vi) Sixth, (A) 25% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 75% to all Unitholders, Pro Rata,
until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and 

(vii) Thereafter, (A) 50% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 50% to all Unitholders, Pro
Rata; 
 provided, however, if the Minimum Quarterly Distribution, the First Target Distribution, the Second Target Distribution and the Third
Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made solely in accordance with Section
6.4(a)(vii). 
 (b) After the Subordination Period. Subject to Section 16.3(b) and Section 17.3(b), Available Cash with respect
to any Quarter after the Subordination Period (which Quarter may include the date on which the Subordination Period ends) that is deemed to be Operating Surplus pursuant to the provisions of Section 6.3 or Section 6.5 shall be distributed as
follows, except as otherwise required in respect of additional Partnership Interests issued pursuant to Section 5.6(b): 

(i) First, to all Unitholders, Pro Rata, until there has been distributed in respect of each Unit then Outstanding an amount
equal to the Minimum Quarterly Distribution for such Quarter; 
 (ii) Second, to all Unitholders, Pro Rata, until there has
been distributed in respect of each Unit then Outstanding an amount equal to the excess of the First Target Distribution over the Minimum Quarterly Distribution for such Quarter; 

(iii) Third, (A) 15% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 85% to all Unitholders, Pro Rata,
until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Second Target Distribution over the First Target Distribution for such Quarter; 

(iv) Fourth, (A) 25% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 75% to all Unitholders, Pro Rata,
until there has been distributed in respect of each Unit then Outstanding an amount equal to the excess of the Third Target Distribution over the Second Target Distribution for such Quarter; and 

(v) Thereafter, (A) 50% to the holders of the Incentive Distribution Rights, Pro Rata, and (B) 50% to all Unitholders, Pro
Rata; 

  
 74 

 provided, however, if the Minimum Quarterly Distribution, the First Target Distribution, the Second
Target Distribution and the Third Target Distribution have been reduced to zero pursuant to the second sentence of Section 6.6(a), the distribution of Available Cash that is deemed to be Operating Surplus with respect to any Quarter will be made
solely in accordance with Section 6.4(b)(v). 
 Section 6.5 Distributions of Available Cash from Capital Surplus. Available Cash that
is deemed to be Capital Surplus pursuant to the provisions of Section 6.3(a) shall, subject to Section 16.3(b) and Section 17.3(b), be distributed, unless the provisions of Section 6.3 require otherwise, to the Unitholders, Pro Rata, until the
Minimum Quarterly Distribution has been reduced to zero pursuant to the second sentence of Section 6.6(a). Available Cash that is deemed to be Capital Surplus shall then be distributed to all Unitholders holding Common Units, Pro Rata, until
there has been distributed in respect of each Common Unit then Outstanding an amount equal to the Cumulative Common Unit Arrearage. Thereafter, all Available Cash shall be distributed as if it were Operating Surplus and shall be distributed in
accordance with Section 6.4. 
 Section 6.6 Adjustment of Minimum Quarterly Distribution and Target Distribution Levels. 

(a) The Minimum Quarterly Distribution, Target Distributions, Common Unit Arrearages and Cumulative Common Unit Arrearages shall be
proportionately adjusted in the event of any distribution, combination or subdivision (whether effected by a distribution payable in Units or otherwise) of Units or other Partnership Interests in accordance with Section 5.9. In the event of a
distribution of Available Cash that is deemed to be from Capital Surplus, the then applicable Minimum Quarterly Distribution and Target Distributions shall be adjusted proportionately downward to equal the product obtained by multiplying the
otherwise applicable Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, as the case may be, by a fraction of which the numerator is the Unrecovered Initial Unit Price of the Common
Units immediately after giving effect to such distribution and of which the denominator is the Unrecovered Initial Unit Price of the Common Units immediately prior to giving effect to such distribution. 

(b) The Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target Distribution, shall also be
subject to adjustment pursuant to Section 5.11 and Section 6.9. 

  
 75 

 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 Unitholders holding a Subordinated Unit shall possess all of the rights
and obligations of a Unitholder holding Common Units hereunder with respect to such converted Subordinated Units, including the right to vote as a Common Unitholder and the right to participate in allocations of income, gain, loss and deduction and
distributions made with respect to Common Units; provided, however, that such converted Subordinated Units shall remain subject to the provisions of Section 5.5(c)(ii), Section 6.1(d)(xi)(A), Section 6.7(b) and Section 6.7(c). 

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

  
 76 

 (b) A Unitholder shall not be permitted to transfer an IDR Reset Common Unit (other than a
transfer to an Affiliate) if the remaining balance in the transferring Unitholder’s Capital Account with respect to the retained IDR Reset Common Units would be negative after giving effect to the allocation under Section 5.5(c)(iii). 

(c) A holder of an IDR Reset Common Unit that was issued in connection with an IDR Reset Election pursuant to Section 5.11 shall not be issued
a Common Unit Certificate pursuant to Section 4.1 (if the Common Units are evidenced by Certificates) or evidence of the issuance of uncertificated Common Units, and shall not be permitted to transfer such Common Unit to a Person that is not an
Affiliate of such holder, until such time as the General Partner determines, based on advice of counsel, that each such IDR Reset Common Unit should have, as a substantive matter, like intrinsic economic and federal income tax characteristics, in
all material respects, to the intrinsic economic and federal income tax characteristics of an IPO Common Unit. In connection with the condition imposed by this Section 6.8(c), the General Partner may take whatever steps are required to provide
economic uniformity to such IDR Reset Common Units in preparation for a transfer of such IDR Reset Common Units, including the application of Section 5.5(c)(iii), Section 6.1(d)(xi)(B), or Section 6.1(d)(xi)(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 shall reduce the Minimum Quarterly Distribution and the Target Distributions by the amount of income or withholding taxes that are payable by reason of any such new legislation or
interpretation (the “Incremental Income Taxes”) in the manner provided in this Section 6.9. If in accordance with the foregoing the General Partner reduces the Minimum Quarterly Distribution and the Target Distributions for
any Quarter with respect to 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 such
Incremental Income Taxes; provided that any difference between such estimate and the actual liability for Incremental Income Taxes for such Quarter may, to the extent determined by the General Partner, be taken into account in determining the
Estimated Incremental Quarterly Tax Amount with respect to each Quarter in which any such difference can be determined. For each such Quarter, the Minimum Quarterly Distribution, First Target Distribution, Second Target Distribution and Third Target
Distribution, shall be the product obtained by multiplying (a) the amounts therefor that are set out herein prior to the application of this Section 6.9 times (b) the quotient obtained by dividing (i) Available Cash with respect to such Quarter by
(ii) the sum of Available Cash with respect to such Quarter and the Estimated Incremental Quarterly Tax Amount for such Quarter, as determined by the General Partner. For purposes of the foregoing, Available Cash with respect to a Quarter will be
deemed reduced by the Estimated Incremental Quarterly Tax Amount for that Quarter.

 (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 cash held by the Partnership; 

(vii) the selection and dismissal of employees (including employees having titles such as “president,” “vice
president,” “secretary” and “treasurer”) and agents, internal and outside attorneys, accountants, consultants and contractors 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 Partners and Indemnitees;

restrictions set forth in Section 2.4; 
 (x) the control of any matters affecting the rights and obligations of the

(xiii) the purchase, sale or other acquisition or disposition of Partnership Interests (subject to Section 16.5(b)(ii) and
Section 17.5(b)(ii) with respect to any Senior Securities), or the issuance of Derivative Partnership Interests (subject to Section 16.5(b)(ii) and Section 17.5(b)(ii)); 

(xiv) the undertaking of any action in connection with the Partnership’s participation in the management of any Group
Member; and 
 (xv) the entering into of agreements with any of its Affiliates to render services to a Group Member or to

 79 

 (b) Notwithstanding any other provision of this Agreement, any Group Member Agreement, the
Delaware Act or any applicable law, rule or regulation, each of the Partners and each other Person who may acquire an interest in Partnership Interests hereby (i) approves, ratifies and confirms the execution, delivery and performance by the parties
thereto of this Agreement and the Group Member Agreement of each other Group Member, the Underwriting Agreement and the other agreements described in or filed as exhibits to the Registration Statement that are related to the transactions
contemplated by the Registration Statement (collectively, the “Transaction Documents”) (in each case other than this Agreement, without giving effect to any amendments, supplements or restatements thereof entered into after
the date such Person becomes bound by the provisions of this Agreement); (ii) agrees that the General Partner (on its own or on behalf of the Partnership) is or was authorized to execute, deliver and perform the agreements referred to in clause (i)
of this sentence and the other agreements, acts, transactions and matters described in or contemplated by the Registration Statement on behalf of the Partnership without any further act, approval or vote of the Partners or the other Persons who may
acquire an interest in Partnership Interests or otherwise bound by this Agreement; and (iii) agrees that the execution, delivery or performance by the General Partner, any 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 Article XV) shall not constitute a breach by the General Partner of any
duty or any other obligation of any type whatsoever that the General Partner may owe the Partnership or the Limited Partners or any other Persons under this Agreement (or any other agreements) or of any duty existing at law, in equity or otherwise.

 Section 7.2 Certificate of Limited Partnership. The General Partner has caused the Certificate of Limited Partnership to be
filed with the Secretary of State of the State of Delaware as required by the Delaware Act. The General Partner shall use all reasonable efforts to cause to be filed such other certificates or documents that the General Partner determines to be
necessary or appropriate for the formation, continuation, qualification and operation of a limited partnership (or a partnership in which the limited partners have limited liability) in the State of Delaware or any other state in which the
Partnership may elect to do business or own property. To the extent the General Partner determines such action to be necessary or appropriate, the General Partner shall file amendments to and restatements of the Certificate of Limited
Partnership and do all things to maintain the Partnership as a limited partnership (or a partnership or other entity in which the limited partners have limited liability) under the laws of the State of Delaware or of any other state in which the
Partnership may elect to do business or own property. Subject to the terms of Section 3.3(a), the General Partner shall not be required, before or after filing, to deliver or mail a copy of the Certificate of Limited Partnership, any
qualification document or any amendment thereto to any Limited Partner. 
 Section 7.3 Restrictions on the General
Partner’s Authority to Sell Assets of the Partnership Group. Except as provided in Article XII, Article XIV, Article XVI and Article XVII, 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 

  
 80 

 
transactions without the approval of holders of a Unit Majority or any approval required pursuant to Article XVI or Article XVII; provided, however, that this provision shall not preclude
or limit the General Partner’s ability to mortgage, pledge, hypothecate or grant a security interest in all or substantially all of the assets of the Partnership Group and shall not apply to any forced sale of any or all of the assets of the
Partnership Group pursuant to the foreclosure of, or other realization upon, any such encumbrance. 
 Section 7.4 Reimbursement of 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 payments it makes on behalf of the Partnership Group for salary, bonus, incentive compensation and other amounts paid to any Person who is an employee of the
General Partner that manages the business and affairs of the Partnership Group, and (ii) all other overhead and general and administrative expenses allocable to the Partnership Group that are incurred by the General Partner in connection with the
General Partner’s management of the Partnership Group’s business and affairs (including expenses allocated to the General Partner by its Affiliates). The General Partner shall determine the expenses that are allocable to the Partnership
Group. Reimbursements pursuant to this Section 7.4 shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7. This provision does not affect the ability of the General Partner and its
Affiliates to enter into an agreement to provide services to any Group Member for a fee or otherwise than for cost. 
 (c) The General
Partner, without the approval of the Limited Partners (who shall have no right to vote in respect thereof), may propose and adopt on behalf of the Partnership employee benefit plans, employee programs and employee practices (including plans,
programs and practices involving the issuance of Partnership Interests or options to purchase or rights, warrants or appreciation rights or phantom or tracking interests relating to Partnership Interests), or cause the Partnership to issue
Partnership Interests or Derivative Partnership Interests in connection with, or pursuant to, any employee benefit plan, employee program or employee practice maintained or sponsored by the General Partner or any of its Affiliates in each case for
the benefit of employees and directors of the General Partner or any of its Affiliates, in respect of services performed, directly or indirectly, for the benefit of the Partnership Group. The Partnership agrees to issue and sell to the General
Partner or any of its Affiliates any Partnership Interests or Derivative Partnership Interests that the General Partner or such Affiliates are obligated to provide to any employees, consultants and directors pursuant to any such employee benefit
plans, employee programs or employee practices. Expenses incurred by the General Partner in connection with any such plans, programs and practices (including the net cost to the General Partner or such Affiliates of Partnership Interests or
Derivative Partnership Interests purchased by the General Partner or such Affiliates from the Partnership to fulfill options or awards under such plans, programs and practices) shall be reimbursed in accordance with

  
 81 

 
Section 7.4(b). Any and all obligations of the General Partner under any employee benefit plans, employee programs or employee practices adopted by the General Partner as permitted by this
Section 7.4(c) shall constitute obligations of the General Partner hereunder and shall be assumed by any successor General Partner approved pursuant to Section 11.1 or Section 11.2 or the transferee of or successor to all of the General
Partner’s General Partner Interest pursuant to Section 4.6. 
 (d) The General Partner and its Affiliates may charge any member of the
Partnership Group a management fee to the extent necessary to allow the Partnership Group to reduce the amount of any state franchise or income tax or any tax based upon the revenues or gross margin of any member of the Partnership Group if the tax
benefit produced by the payment of such management fee or fees exceeds the amount of such fee or fees. 
 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) subject to the limitations contained in the Omnibus Agreement, the performance of its obligations under the Omnibus Agreement. 

(b) Except as provided in the Omnibus Agreement or any Group Member Agreement, each Unrestricted Person (other than the General Partner) shall
have the right to engage in businesses of every type and description and other activities for profit and to engage in and possess an interest in other business ventures of any and every type or description, whether in businesses engaged in or
anticipated to be engaged in by any Group Member, independently or with others, including business interests and activities in direct competition with the business and activities of any Group Member, and none of the same shall constitute a breach of
this Agreement or any duty otherwise existing at law, in equity or otherwise, to any Group Member or any Partner; provided such Unrestricted Person does not engage in such business or activity using confidential or proprietary information
provided by or on behalf of the Partnership to such Unrestricted Person. 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 (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 

  
 82 

 
be a breach of any duty otherwise existing at law, in equity or otherwise, 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). Except as provided in the Omnibus Agreement or any Group Member Agreement, no Unrestricted Person (including the General Partner) who acquires knowledge of a potential transaction, agreement, arrangement or other matter that may be
an opportunity for the Partnership, shall have any duty to communicate or offer such opportunity to the Partnership, and such Unrestricted Person (including the General Partner) shall not be liable to the Partnership, to any Limited Partner or any
other Person bound by this Agreement for breach of any duty otherwise existing at law, in equity or otherwise, 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 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, Series A
Preferred Units, Series B Preferred Units or other Partnership Interests in addition to those acquired on or prior to the date hereof and, except as otherwise provided in this Agreement, shall be entitled to exercise, at their option, all rights
relating to all Units, Series A Preferred Units, Series B Preferred Units and/or other Partnership Interests acquired by them. The term “Affiliates” when used in this Section 7.5(d) with respect to the General Partner shall not include any
Group Member. 
 (e) Notwithstanding anything to the contrary in this Agreement, to the extent that the provisions of this Agreement purport
or are interpreted to have the effect of restricting or eliminating any duties (including fiduciary duties) otherwise existing at law, in equity or otherwise, owed by the General Partner or other Person to the Partnership, its Limited Partners or
any other Person bound by this Agreement or to constitute a waiver or consent by the Limited Partners or any other Person bound by this Agreement to any such restriction, such provisions shall be deemed to have been approved by the Partners and
every other Person bound by this Agreement. 
 Section 7.6 Loans from the General Partner; Loans or Contributions from the Partnership or
Group Members. 
 (a) The General Partner or any of its Affiliates may lend to any Group Member, and any Group Member may borrow from
the General Partner or any of its Affiliates, funds needed or desired by the Group Member for such periods of time and in such amounts as the General Partner may determine; provided, however, that in any such case the lending party may not
charge the borrowing party interest at a rate greater than the rate that would be charged the 

  
 83 

 
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 or any
other obligation of any type whatsoever, expressed or implied, of the General Partner or its Affiliates to the Partnership or the Limited Partners existing hereunder, or existing at law, in equity or otherwise by reason of the fact that the purpose
or effect of such borrowing is directly or indirectly to 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 omitting or refraining to act) in such capacity on behalf of or for the benefit of the Partnership; provided, that the
Indemnitee shall not be indemnified and held harmless pursuant to this Agreement if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Indemnitee
is seeking indemnification pursuant to this Agreement, the Indemnitee acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Indemnitee’s conduct was unlawful; provided,
further, no indemnification pursuant to this Section 7.7 shall be available to any Indemnitee (other than a Group Member) with respect to any such Affiliate’s obligation pursuant to the Transaction Documents. Any indemnification pursuant to
this Section 7.7 shall be made only out of the assets of the Partnership, it being agreed that the General Partner shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to
the Partnership to enable it to effectuate such indemnification. 

  
 84 

 (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
this Agreement, any other agreement, pursuant to any vote of the holders of Outstanding Limited Partner Interests entitled to vote on such matter, as a matter of law, in equity or otherwise, both as to actions in the Indemnitee’s capacity as an
Indemnitee and as to actions in any other capacity (including any capacity under the Underwriting Agreement or Master Formation Agreement), and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the
benefit of the heirs, successors, assigns and administrators of the Indemnitee. 
 (d) The Partnership may purchase and maintain (or
reimburse the General Partner or its Affiliates for the cost of) insurance, on behalf of the General Partner, its Affiliates and such other Persons as the General Partner shall determine, against any liability that may be asserted against, or
expense that may be incurred by, such Person in connection with the Partnership’s activities or such Person’s activities on behalf of the Partnership, regardless of whether the Partnership would have the power to indemnify such Person
against such liability under the provisions of this Agreement. 
 (e) For purposes of this Section 7.7, the Partnership shall be deemed to
have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries
of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 7.7(a); and action taken or omitted by it with respect to any
employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the
Partnership. 
 (f) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of the indemnification
provisions set forth in this Agreement. 
 (g) An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7
because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement. 

  
 85 

 (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. 

(j) TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, AND SUBJECT TO SECTION 7.7(a), THE PROVISIONS OF THE INDEMNIFICATION PROVIDED IN THIS
SECTION 7.7 ARE INTENDED BY THE PARTNERS TO APPLY EVEN IF SUCH PROVISIONS HAVE THE EFFECT OF EXCULPATING THE INDEMNITEE FROM LEGAL RESPONSIBILITY FOR THE CONSEQUENCES OF SUCH PERSON’S NEGLIGENCE, FAULT OR OTHER CONDUCT. 

Section 7.8 Liability of Indemnitees. 

(a) Notwithstanding anything to the contrary set forth in this Agreement, no Indemnitee shall be liable for monetary damages to the
Partnership, the Limited Partners, or any other Persons who 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) 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. 

  
 86 

 Section 7.9 Resolution of Conflicts of Interest; Standards of Conduct and Modification of
Duties. 
 (a) Unless otherwise expressly provided in this Agreement or any Group Member Agreement, whenever a potential conflict of
interest exists or arises between the General Partner or any of its Affiliates, on the one hand, and the Partnership, any Group Member or any Partner, on the other, any resolution or course of action by the General Partner or its Affiliates in
respect of such conflict of interest shall be permitted and deemed approved by all Partners, and shall not constitute a breach of this Agreement, of any Group Member Agreement, of any agreement contemplated herein or therein, or of any duty stated
or implied by law or equity, if the resolution or course of action in respect of such conflict of interest is (i) approved by Special Approval, (ii) approved by the vote of a majority of the Outstanding Common Units (excluding Common Units owned by
the General Partner and its Affiliates), (iii) determined by the Board of Directors of the General Partner to be on terms no less favorable to the Partnership than those generally being provided to or available from unrelated third parties or (iv)
determined by the Board of Directors of the General Partner to be 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. Unless otherwise expressly provided in this Agreement or any Group Member Agreement, whenever the General Partner makes a
determination to refer any potential conflict of interest for Special Approval, seek Unitholder Approval or adopt a resolution or course of action that has not received Special Approval or Unitholder Approval, then the General Partner shall be
entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty or obligation whatsoever to the Partnership or any Limited Partner, and the General Partner shall not, to
the fullest extent permitted by law, be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule
or regulation or at equity, and the General Partner in making such determination or taking or declining to take such other action shall be permitted to do so in its sole and absolute discretion. If Special Approval is sought, then it shall be
presumed that, in making its decision, the Conflicts Committee acted in good faith, and if the Board of Directors of the General Partner determines that the resolution or course of action taken with respect to a conflict of interest satisfies either
of the standards set forth in clauses (iii) or (iv) above or that a director satisfies the eligibility requirements to be a member of the Conflicts Committee, then it shall be presumed that, in making its decision, the Board of Directors of the
General Partner acted in good faith. In any proceeding brought by any Limited Partner or by or on behalf of such Limited Partner or any other Limited Partner or the Partnership challenging any action by the Conflicts Committee with respect to any
matter referred to the Conflicts Committee for Special Approval by the General Partner, any action by the Board of Directors of the General Partner in 

  
 87 

 
determining whether the resolution or course of action taken with respect to a conflict of interest satisfies either of the standards set forth in clauses (iii) or (iv) above or whether a
director satisfies the eligibility requirements to be a member of the Conflicts Committee, the Person bringing or prosecuting such proceeding shall have the burden of overcoming the presumption that the Conflicts Committee or the Board of Directors
of the General Partner, as applicable, acted in good faith; in all cases subject to the provisions for conclusive determination in Section 7.9(b). 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 are hereby approved by all Partners and shall not constitute a breach of this Agreement or any such duty. 

(b) Whenever the General Partner or the Board of Directors, or any committee thereof (including the Conflicts Committee), makes a
determination or takes or declines to take any other action, or any Affiliate of the General Partner causes the General Partner to do so, in its capacity as the general partner of the Partnership as opposed to in its individual capacity, whether
under this Agreement, any Group Member Agreement or any other agreement, then, unless another express standard is provided for in this Agreement, the General Partner, the Board of Directors or such committee or such Affiliates causing the General
Partner to do so, shall make such determination or take or decline to take such other action in good faith and shall not be subject to any other or different standards (including fiduciary standards) imposed by this Agreement, any Group Member
Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity. A determination or other action or inaction will conclusively be deemed to be in “good faith” for all purposes
of this Agreement, if the Person or Persons making such determination or taking or declining to take such other action subjectively believe that the determination or other action or inaction is in the best interests of the Partnership Group;
provided, that if the Board of Directors of the General Partner is making a determination or taking or declining to take an action pursuant to clause (iii) or clause (iv) of the first sentence of Section 7.9(a), then in lieu thereof, such
determination or other action or inaction will conclusively be deemed to be in “good faith” for all purposes of this Agreement if the members of the Board of Directors of the General Partner making such determination or taking or declining
to take such other action subjectively believe that the determination or other action or inaction meets the standard set forth in clause (iii) or clause (iv) of the first sentence of Section 7.9(a), as applicable; provided, further, that if
the Board of Directors of the General Partner is making a determination that a director satisfies the eligibility requirements to be a member of a Conflicts Committee, then in lieu thereof, such determination will conclusively be deemed to be in
“good faith” for all purposes of this Agreement if the members of the Board of Directors of the General Partner making such determination subjectively believe that the director satisfies the eligibility requirements to be a member of the
Conflicts Committee, as the case may be. 
 (c) Whenever the General Partner makes a determination or takes or declines to take any other
action, or any of its Affiliates causes it to do so, in its individual capacity as opposed to in its capacity as the general partner of the Partnership, whether under this Agreement, any Group Member Agreement or any other agreement contemplated
hereby or otherwise, then the General Partner, or such Affiliates causing it to do so, are entitled, to the fullest extent permitted by law, to make such determination or to take or decline to take such other action free of any duty or obligation
whatsoever to the Partnership or any Limited Partner, and the General Partner, 

  
 88 

 
or such Affiliates causing it to do so, shall not, to the fullest extent permitted by law, be required to act in good faith or pursuant to any other standard imposed by this Agreement, any Group
Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the Person or Persons making such determination or taking or declining to take such other action shall be
permitted to do so in their sole and absolute discretion. By way of illustration and not of limitation, whenever the phrase, “the General Partner at its option,” or some variation of that phrase, is used in this Agreement, it indicates
that the General Partner is acting in its individual capacity. For the avoidance of doubt, whenever the General Partner votes or transfers its Partnership Interests, or refrains from voting or transferring its Partnership Interests, it shall be
acting in its individual capacity. 
 (d) The General Partner’s organizational documents may provide that determinations to take or
decline to take any action in its individual, rather than representative, capacity may or shall be determined by its members, if the General Partner is a limited liability company, stockholders, if the General Partner is a corporation, or the
members or stockholders of the General Partner’s general partner, if the General Partner is a partnership. 
 (e) Notwithstanding
anything to the contrary in this Agreement, the General Partner and its Affiliates shall have no duty or obligation, express or implied, to (i) sell or otherwise dispose of any asset of the Partnership Group other than in the ordinary course of
business or (ii) permit any Group Member to use any facilities or assets of the General Partner and its Affiliates, except as may be provided in contracts entered into from time to time specifically dealing with such use. Any determination by the
General Partner or any of its Affiliates to enter into such contracts shall be at its option. 
 (f) Except as expressly set forth in this
Agreement or required by the Delaware Act, neither the General Partner nor any other Indemnitee shall have any duties or liabilities, including fiduciary duties, to the Partnership or any Limited Partner and the provisions of this Agreement, to the
extent that they restrict, eliminate or otherwise modify the duties and liabilities, including fiduciary duties, of the General Partner or any other Indemnitee otherwise existing at law or in equity, are agreed by the Partners to replace such other
duties and liabilities of the General Partner or such other Indemnitee. 
 (g) The Unitholders hereby authorize the General Partner, on
behalf of the Partnership as a general partner or managing member of a Group Member, to approve actions by the general partner or managing member of such Group Member similar to those actions permitted to be taken by the General Partner pursuant to
this Section 7.9. 
 Section 7.10 Other Matters Concerning the General Partner. 

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

  
 89 

 (b) The General Partner and any other Indemnitee may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers and other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the advice or opinion (including an Opinion of Counsel) of such Persons as to matters
that the General Partner or such Indemnitee, respectively, reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such
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. The General Partner may cause the Partnership to purchase or otherwise
acquire Partnership Interests or Derivative Partnership Interests; provided that, except as permitted pursuant to Section 4.10, the General Partner may not cause any Group Member to purchase Subordinated Units during the Subordination
Period. As long as Partnership Interests are held by any Group Member, such Partnership Interests shall not be considered Outstanding for any purpose, except as otherwise provided herein. The General Partner or any Affiliate of the General
Partner may also purchase or otherwise acquire and sell or otherwise dispose of Partnership Interests for its own account, subject to the provisions of Articles IV and X. 

Section 7.12 Reliance by Third Parties. Notwithstanding anything to the contrary in this Agreement, any Person (other than the General
Partner and its Affiliates) 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 (other than the General Partner and its Affiliates) 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.

 Section 7.13 Pension Plan Liabilities. Any acceptance or assumption of assets or
liabilities from any pension plan as defined in Section 3(2) of ERISA, whether or not subject to ERISA, that is sponsored or maintained by either Sponsor Party or its Affiliates shall be approved by Special Approval. To the fullest extent permitted
by law, each Sponsor Party shall indemnify and hold harmless the Partnership and any other Group Member from and against any and all losses, damages, liabilities, claims, demands, causes of action, judgments, settlements, fines, penalties, costs and
expenses (including court costs and reasonable attorneys’ and experts’ fees) of any and every kind or character, known or unknown, fixed or contingent, arising from or related to any acceptance or assumption by any Group Member of assets
or liabilities from any pension plan, as defined in Section 3(2) of ERISA, whether or not subject to ERISA, maintained by such Sponsor Party or its Affiliates; provided, however, that notwithstanding anything herein to the contrary, in no
event shall a Sponsor Party’s indemnification obligations cover or include consequential, indirect, incidental, punitive, exemplary, special or similar damages or lost profits suffered by the Partnership or any other Group Member. 

ARTICLE VIII

General Partner determines to be necessary or appropriate.

 Section 8.3 Reports. 

(a) Whether or not the Partnership is subject to the requirement to file reports with the Commission, as soon as practicable, but in no event
later than 105 days after the close of each fiscal year of the Partnership (or such shorter period as required by the Commission), the General Partner shall cause to be mailed or made available, by any reasonable means (including posting on or
accessible through the Partnership’s or the Commission’s website) to each Record Holder of a Partnership Interest as of a date selected by the General Partner, an annual report containing financial statements of the Partnership for such
fiscal year of the Partnership, presented in accordance with U.S. GAAP, including a balance sheet and statements of operations, Partnership equity and cash flows, such statements to be audited by a firm of independent public accountants selected by

containing unaudited financial statements of the Partnership for such Quarter and year-to-date period, presented in accordance with U.S. GAAP, including a balance sheet and statements of operations, Partnership equity and cash flows, and such other
information as may be required by applicable law, regulation or rule of the Commission or any National Securities Exchange on which the Partnership Interests are listed or admitted to trading, or as the General Partner determines to be necessary or
appropriate.

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

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

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

pursuant to Article XIV, and except as provided in Section 4.9, each transferee of, or other such Person acquiring, a Limited Partner Interest (including any nominee, agent or representative acquiring such Limited Partner Interests for the account
of another Person or Group, which nominee, agent or representative shall be subject to Section 10.1(c) below) (i) shall be admitted to the Partnership as a Limited Partner with respect to the Limited Partner Interests so transferred or issued to

any of the Partners. A Person may not become a Limited Partner without acquiring a Limited Partner Interest and becoming the Record Holder of such Limited Partner Interest. The rights and obligations of a Person who is an Ineligible Holder shall be
determined in accordance with Section 4.9. 
 (c) With respect to Units that are held for a Person’s account by another Person that is
the Record Holder (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), such Record Holder shall, in exercising the rights of a Limited Partner in respect of such Units, including the right to
vote, on any matter, and unless the arrangement between such Persons provides otherwise, take all action as a Limited Partner by virtue of being the Record Holder of such Units in accordance with the direction of the Person who is the beneficial
owner of such Units, and the Partnership shall be entitled to assume such Record Holder is so acting without further inquiry. The provisions of this Section 10.1(c) are subject to the provisions of Section 4.3. 

(d) The name and mailing address of each Record Holder shall be listed in the Register. The General Partner shall update the Register from
time to time as necessary to reflect accurately the information therein (or shall cause the Transfer Agent to do so, as applicable).

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).

 94 

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

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

ARTICLE XI

OR REMOVAL OF PARTNERS

 95 

 (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 or against the General Partner; or 

(vi) (A) if the General Partner is a corporation, a certificate of dissolution or its equivalent is filed for the General

 If an Event of
Withdrawal specified in Section 11.1(a)(iv), (v) or (vi)(A), (B), (C) or (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 during the period beginning on the IPO Closing Date and
ending at 12:00 midnight, Central Time, on June 30, 2024, 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 cause any Group Member to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not already so treated or taxed); (ii) at any time after
12:00 midnight, Central Time, on June 30, 2024, 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 such notice; (iii) at any time that
the General Partner ceases to be the General Partner pursuant to Section 11.1(a)(ii) or is removed pursuant to Section 11.2; or (iv) notwithstanding clause (i) of this sentence, at any time that the General Partner voluntarily withdraws by giving at

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 pursuant to Section 11.1(a)(i), the holders of a Unit Majority, may,
prior to the effective date of such withdrawal, elect a successor General Partner. The Person so elected as successor General Partner shall automatically become the successor general partner or managing

  
 96 

 
member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. Any successor General Partner elected in accordance with
the terms of this Section 11.1 shall be subject to the provisions of Section 10.2. 
 Section 11.2 Removal of the General
Partner. The General Partner may be removed if such removal is approved by the Unitholders holding at least 75% of the Outstanding Units (including Units held by the General Partner and its Affiliates) voting as a single class. Any
such action by such holders for removal of the General Partner must also provide for the election of a successor General Partner by the Unitholders holding a majority of the outstanding Common Units voting as a class and Unitholders holding a
majority of the outstanding Subordinated Units (if any Subordinated Units are then Outstanding) voting as a class (including, in each case, Units held by the General Partner and its Affiliates). Such removal shall be effective immediately
following the admission of a successor General Partner pursuant to Section 10.2. The removal of the General Partner shall also automatically constitute the removal of the General Partner as general partner or managing member, to the extent
applicable, of the other Group Members of which the General Partner is a general partner or a managing member. If a Person is elected as a successor General Partner in accordance with the terms of this Section 11.2, such Person shall, upon
admission pursuant to Section 10.2, automatically become a successor general partner or managing member, to the extent applicable, of the other Group Members of which the General Partner is a general partner or a managing member. The right of
the holders of Outstanding Units to remove the General Partner shall not exist or be exercised unless the Partnership has received an opinion opining as to the matters covered by a Withdrawal Opinion of Counsel. Any successor General Partner
elected in accordance with the terms of this Section 11.2 shall be subject to the provisions of Section 10.2. 
 Section 11.3 Interest of
Departing General Partner and Successor General Partner. 
 (a) In the event of (i) withdrawal of the General Partner under
circumstances where such withdrawal does not violate this Agreement or (ii) removal of the General Partner by the holders of Outstanding Units under circumstances where Cause does not exist, if the successor General Partner is elected in accordance
with the terms of Section 11.1 or Section 11.2, the Departing General Partner shall have the option, exercisable prior to the 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 (including, in the case of EH II, the EH Management Units) 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

  
 97 

 
shall have the option, exercisable prior to the effective date of the withdrawal or removal of such Departing General Partner (or, in the event the business of the Partnership is continued, prior
to the date the business of the Partnership is continued), to purchase the Combined Interest for such fair market value of such Combined Interest. In either event, the Departing General Partner shall be entitled to receive all reimbursements
due such Departing General Partner pursuant to Section 7.4, including any employee-related liabilities (including severance liabilities), incurred in connection with the termination of any employees employed by the Departing General Partner or its
Affiliates (other than any Group Member) for the benefit of the Partnership or the other Group Members. 
 For purposes of this Section
11.3(a), the fair market value of the Combined Interest shall be determined by agreement between the Departing General Partner and its successor or, failing agreement within 30 days after the effective date of such Departing General Partner’s
withdrawal or removal, by an independent investment banking firm or other independent expert selected by the Departing General Partner and its successor, which, in turn, may rely on other experts, and the determination of which shall be conclusive
as to such matter. If such parties cannot agree upon one independent investment banking firm or other independent expert within 45 days after the effective date of such withdrawal or removal, then the Departing General Partner shall designate an
independent investment banking firm or other independent expert, the Departing General Partner’s successor shall designate an independent investment banking firm or other independent expert, and such firms or experts shall mutually select a
third independent investment banking firm or independent expert, which third independent investment banking firm or other independent expert shall determine the fair market value of the Combined Interest. In making its determination, such third
independent investment banking firm or other independent expert may consider the then current trading price of Units on any National Securities Exchange on which Units are then listed or admitted to trading, the value of the Partnership’s
assets, the rights and obligations of the Departing General Partner, the value of the Incentive Distribution Rights and the General Partner Interest and other factors it may deem relevant. 

(b) If the Combined Interest is not purchased in the manner set forth in Section 11.3(a), the Departing General Partner (or its transferee)
shall become a Limited Partner and its Combined Interest shall be converted into Common Units pursuant to a valuation made by an investment banking firm or other independent expert selected pursuant to Section 11.3(a), without reduction in such
Partnership Interest (but subject to proportionate dilution by reason of the admission of its successor). Any successor General Partner shall indemnify the Departing General Partner (or its transferee) as to all debts and liabilities of the
Partnership arising on or after the date on which the Departing General Partner (or its transferee) becomes a Limited Partner. For purposes of this Agreement, conversion of the Combined Interest of the Departing General Partner to Common Units
will be characterized as if the Departing General Partner (or its transferee) contributed its Combined Interest to the Partnership in exchange for the newly issued Common Units. 

(c) If a successor General Partner is elected in accordance with the terms of Section 11.1 or Section 11.2 (or if the business of the
Partnership is continued pursuant to Section 12.2 and the successor General Partner is not the former General Partner) and the option described in Section 11.3(a) is not exercised by the party entitled to do so, the successor General Partner

  
 98 

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

ARTICLE XII

 99 

 (b) an election to dissolve the Partnership by the General Partner that is approved by the

pursuant to Section 11.1 or Section 11.2, then, to the maximum extent permitted by law, within 90 days thereafter, or (b) dissolution of the Partnership upon an event constituting an Event of Withdrawal as defined in Section 11.1(a)(iv), (v) or
(vi), then, to the maximum extent permitted by law, within 180 days thereafter, the holders of a Unit Majority may elect to continue the business of the Partnership on the same terms and conditions set forth in this Agreement by appointing as a
successor General Partner a Person approved by the holders of a Unit Majority. Unless such an election is made within the applicable time period as set forth above, the Partnership shall conduct only activities necessary to wind up its affairs. If
such an election is so made, then: 
 (i) the Partnership shall continue without dissolution unless earlier dissolved in
accordance with this Article XII; 
 (ii) if the successor General Partner is not the former General Partner, then the
interest of the former General Partner shall be treated in the manner provided in Section 11.3; and 
 (iii) the successor
General Partner shall be admitted to the Partnership as General Partner, effective as of the Event of Withdrawal, by agreeing in writing to be bound by this Agreement; 

provided, that the right of the holders of a Unit Majority to approve a successor General Partner and to continue the business of the Partnership shall
not exist and may not be exercised unless the Partnership has received an Opinion of Counsel that (x) the exercise of the right would not result in the loss of limited liability of any Limited Partner under the Delaware Act and (y) neither the
Partnership nor any Group Member would be treated as an association taxable as a corporation or otherwise be taxable as an entity for federal income tax purposes upon the exercise of such right to continue (to the extent not already so treated or
taxed). 
 Section 12.3 Liquidator. Upon dissolution of the Partnership in accordance with the provisions of this Article XII,
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 

  
 100 

 
Subordinated Units 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 voting as a single class. Upon dissolution, removal or resignation of the Liquidator, a successor and
substitute Liquidator (who shall have and succeed to all rights, powers and duties of the original Liquidator) shall within 30 days thereafter be approved by holders of at least a majority of the Outstanding Common Units and Subordinated Units
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 under Section 16.3 and Section 17.3 or 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 distributed as additional liquidation proceeds. 
 (c) Subject to Section 16.10 and Section 17.10,
all property and all cash in excess of that required to discharge liabilities as provided in Section 12.4(b) shall be distributed to the Partners in accordance with, and to the extent of, the positive balances in their respective Capital

  
 101 

 
Accounts, as determined after taking into account all Capital Account adjustments (other than those made by reason of distributions pursuant to this Section 12.4(c)) for the taxable period of the
Partnership during which the liquidation of the Partnership occurs (with such date of occurrence being determined pursuant to Treasury Regulation Section 1.704-1(b)(2)(ii)(g)), and such distribution shall be made by the end of such taxable period
(or, if later, within 90 days after said date of such occurrence). 
 Section 12.5 Cancellation of Certificate of Limited
Partnership. Upon the completion of the distribution of Partnership cash and property as provided in Section 12.4 in connection with the liquidation of the Partnership, the Certificate of Limited Partnership and all qualifications of the
Partnership as a foreign limited partnership in jurisdictions other than the State of Delaware shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken. 

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

permitted by law, the General Partner shall have no duty or obligation to propose or approve any amendment to this Agreement and may decline to do so free of any duty or obligation whatsoever to the Partnership, any Limited Partner or any other
Person bound by this Agreement, and, in declining to propose or approve an amendment to this Agreement, to the fullest extent permitted by law shall not be required to act in good faith or pursuant to any other standard imposed by this Agreement,
any Group Member Agreement, any other agreement contemplated hereby or under the Delaware Act or any other law, rule or regulation or at equity, and the General Partner in determining whether to propose or approve any amendment to this Agreement

Majority, unless a greater or different percentage of Outstanding Units is required under this Agreement, (ii) if applicable pursuant to Section 16.5(b)(i), the holders of at least 66 2⁄3% of the Outstanding Series A Preferred Units and (iii) if applicable pursuant to Section 17.5(b)(i), the holders of at least
66 2⁄3% of the Outstanding Series B Preferred Units. Each proposed amendment that requires the approval of the holders of a specified percentage of Outstanding
Units, Outstanding Series A Preferred Units or Outstanding Series B Preferred 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, Outstanding Series A Preferred Units or Outstanding Series B Preferred Units, as applicable, or call a meeting of the Unitholders, Series A Holders or Series B Holders, as applicable, to
consider and vote on such proposed amendment. The General Partner shall notify all Record Holders upon final adoption of any amendments. The General Partner shall be deemed to have notified all Record Holders as required by this Section 13.2 if it
has posted or made accessible such amendment through the Partnership’s or the Commission’s website. 
 Section 13.3 Amendment
Requirements. 
 (a) Notwithstanding the provisions of Section 13.1 and Section 13.2, no provision of this Agreement that establishes a
percentage of Outstanding Units (including Units deemed 

  
 104 

 
owned by the General Partner) required to take any action shall be amended, altered, changed, repealed or rescinded in any respect that would have the effect of (i) in the case of any provision
of this Agreement other than Section 11.2 or Section 13.4, reducing such percentage or (ii) in the case of Section 11.2 or Section 13.4, increasing such percentages, unless such amendment is approved by the written consent or the affirmative vote of
holders of Outstanding Units whose aggregate Outstanding Units constitute (x) in the case of a reduction as described in subclause (a)(i) hereof, not less than the voting requirement sought to be reduced, (y) in the case of an increase in the
percentage in Section 11.2, not less than 90% of the Outstanding Units, or (z) in the case of an increase in the percentage in Section 13.4, not less than a majority of the Outstanding Units. Notwithstanding the provisions of Section 13.1 and
Section 13.2, no provision of this Agreement that establishes a percentage of Outstanding Series A Preferred Units and Outstanding Series B Preferred Units required to take any action shall be amended, altered, changed, repealed or rescinded in any
respect that would have the effect of reducing or increasing such percentage, unless such amendment is approved by the written consent or the affirmative vote of holders of Outstanding Series A Preferred Units and Outstanding Series B Preferred
Units whose aggregate Outstanding Series A Preferred Units and Outstanding Series B Preferred Units, as applicable, constitute not less than 66 2⁄3% of the
Outstanding Series A Preferred Units and Outstanding Series B Preferred Units, 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 any Limited Partner without its consent, unless such shall be deemed to have occurred as a result of an amendment approved pursuant to Section 13.3(c)
or (ii) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, the General Partner or any of its Affiliates without its consent, which consent
may be given or withheld at its option. 
 (c) Except as provided in Section 14.3, and without limitation of the General Partner’s
authority to adopt amendments to this Agreement without the approval of any Partners as contemplated in Section 13.1, any amendment that would have a material adverse effect on the rights or preferences of any class or series of Partnership
Interests in relation to other classes or series of Partnership Interests must be approved by the holders of not less than a majority of the Outstanding Partnership Interests of the class or series affected. 

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

(e) Except as provided in Section 13.1, this Section 13.3 shall only be amended with the approval of the holders of at least 90% of the
Outstanding Units. 

  
 105 

 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 or Preferred Units of the
class, classes or series for which a meeting is proposed. Limited Partners shall call a special meeting by delivering to the General Partner one or more requests in writing stating that the signing Limited Partners wish to call a special meeting and
indicating the specific purposes for which the special meeting is to be called and the class, classes or series of Units or Preferred Units for which the meeting is proposed. No business may be brought by any Limited Partner before such special
meeting except the business listed in the related request. Within 60 days after receipt of such a call from Limited Partners or within such greater time as may be reasonably necessary for the Partnership to comply with any statutes, rules,
regulations, listing agreements or similar requirements governing the holding of a meeting or the solicitation of proxies for use at such a meeting, the General Partner shall send a notice of the meeting to the Limited Partners either directly or
indirectly. 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 18.1. Limited Partners shall not be
permitted to vote on matters that would cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited Partners’ limited liability under the
Delaware Act or the law of any other state in which the Partnership is qualified to do business. If any such vote were to take place, it shall be deemed null and void to the extent necessary so as not 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 18.1. 
 Section 13.6 Record Date. For purposes of determining the Limited Partners who are Record
Holders of the class or classes of Limited Partner Interests entitled to notice of or to vote at a meeting of the Limited Partners or to give approvals without a meeting as provided in Section 13.11, the General Partner shall set a Record Date,
which shall not be less than 10 nor more than 60 days before (a) the date of the meeting (unless such requirement conflicts with any rule, regulation, guideline or requirement of any National Securities Exchange on which the Units or Preferred Units
are listed or admitted to trading or U.S. federal securities laws, in which case the rule, regulation, guideline or requirement of such National Securities Exchange or U.S. federal securities laws shall govern) or (b) in the event that approvals are
sought without a meeting, the date by which such Limited Partners are requested in writing by the General Partner to give such approvals. 

Section 13.7 Postponement and Adjournment. Prior to the date upon which any meeting of Limited Partners is to be held, the General
Partner may postpone such meeting one or more times for any reason by giving notice to each 

  
 106 

 
Limited Partner entitled to vote at the meeting so postponed of the place, date and hour at which such meeting would be held. Such notice shall be given not fewer than two days before the
date of such meeting and otherwise in accordance with this Article XIII. When a meeting is postponed, a new Record Date need not be fixed unless the aggregate amount of such postponement shall be for more than 45 days after the original meeting
date. Any meeting of Limited Partners may be adjourned by the General Partner one or more times for any reason, including the failure of a quorum to be present at the meeting with respect to any proposal or the failure of any proposal to
receive sufficient votes for approval. No vote of the Limited Partners shall be required for any adjournment. A meeting of Limited Partners may be adjourned by the General Partner as to one or more proposals regardless of whether action
has been taken on other matters. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting and a new Record Date need not be fixed, if the time and place thereof are announced at the meeting at
which the adjournment is taken, unless such adjournment shall be for more than 45 days. At the adjourned meeting, the Partnership may transact any business which might have been transacted at the original meeting. If the adjournment is for more than
45 days or if a new Record Date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given in accordance with this Article XIII. 

Section 13.8 Waiver of Notice; Approval of Meeting. The transactions of any meeting of Limited Partners, however called and
noticed, and whenever held, shall be as valid as if it had occurred at a meeting duly held after call and notice in accordance with Section 13.4 and Section 13.5, 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 of any matters submitted for consideration or to object to the failure to submit for consideration any matters required to be included in
the notice of the meeting, but not so included, if such objection is expressly made at the beginning of the meeting. 
 Section 13.9
Quorum and Voting. The presence, in person or by proxy, of holders of a majority of the Outstanding Units or Preferred Units of the class, classes or series for which a meeting has been called (including Outstanding Units or Preferred
Units deemed owned by the General Partner and its Affiliates) shall constitute a quorum at a meeting of Limited Partners of such class, classes or series unless any such action by the Limited Partners requires approval by holders of a greater
percentage of such class, classes or series of Units or Preferred Units, in which case the quorum shall be such greater percentage. At any meeting of the Limited Partners duly called and held in accordance with this Agreement at which a quorum is
present, the act of Limited Partners holding Outstanding Units or Preferred Units that in the aggregate represent a majority of the Outstanding Units or Preferred Units entitled to vote at such meeting shall be deemed to constitute the act of all
Limited Partners, unless a different percentage is required with respect to such action under the provisions of this Agreement, in which case the act of the Limited Partners holding Outstanding Units or Preferred Units that in the aggregate
represent at least such different percentage shall be required. The Limited Partners present at a duly called or held 

  
 107 

 
meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the exit of enough Limited Partners to leave less than a quorum, if any action taken
(other than adjournment) is approved by the required percentage of Outstanding Units or Preferred Units specified in this Agreement. 

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

Section 13.11 Action Without a Meeting. If authorized by the General Partner, any action that may be taken at a meeting of the
Limited Partners may be taken without a meeting if an approval in writing setting forth the action so taken is signed by Limited Partners owning not less than the minimum percentage of the Outstanding Units or Preferred Units (including Units or
Preferred Units deemed owned by the General Partner and its Affiliates) that would be necessary to authorize or take such action at a meeting at which all the Limited Partners were present and voted (unless such provision conflicts with any rule,
regulation, guideline or requirement of any National Securities Exchange on which the Units or Preferred Units are listed or admitted to trading, in which case the rule, regulation, guideline or requirement of such National Securities Exchange shall
govern). Prompt notice of the taking of action without a meeting shall be given to the Limited Partners who have not approved in writing. The General Partner may specify that any written ballot submitted to Limited Partners for the purpose of taking
any action without a meeting shall be returned to the Partnership within the time period, which shall be not less than 20 days, specified by the General Partner. If a ballot returned to the Partnership does not vote all of the Outstanding Units or
Preferred Units held by such Limited Partners, the Partnership shall be deemed to have failed to receive a ballot for the Outstanding Units or Preferred Units that were not voted. If approval of the taking of any permitted action by the Limited
Partners is solicited by any Person other than by or on behalf of the General Partner, the written approvals shall have no force and effect unless and until (a) approvals sufficient to take the action proposed are deposited with the Partnership in
care of the General Partner, (b) approvals sufficient to take the action proposed are dated as of a date not more than 90 days prior to the date sufficient approvals are first deposited with the Partnership and (c) an Opinion of Counsel is delivered
to the General Partner to the effect that the exercise of such right and the action proposed to be taken with respect to any particular 

  
 108 

 
matter (i) will not cause the Limited Partners to be deemed to be taking part in the management and control of the business and affairs of the Partnership so as to jeopardize the Limited
Partners’ limited liability, and (ii) is otherwise permissible under the state statutes then governing the rights, duties and liabilities of the Partnership and the Partners. 

Section 13.12 Right to Vote and Related Matters. 

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

(b) Only those Record Holders of the Outstanding Series A Preferred Units on the Record Date set pursuant to Section 13.6 (and also subject to
the limitations set forth in Section 16.5) shall be entitled to notice of, and to vote at, a meeting of Limited Partners holding Series A Preferred Units or to act with respect to matters as to which the holders of the Outstanding Series A Preferred
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 Series A Preferred Units shall be deemed to be references to the votes or acts of the Record Holders
of such Outstanding Series A Preferred Units. 
 (c) Only those Record Holders of the Outstanding Series B Preferred Units on the
Record Date set pursuant to Section 13.6 (and also subject to the limitations set forth in Section 17.5) shall be entitled to notice of, and to vote at, a meeting of Limited Partners holding Series B Preferred Units or to act with respect to matters
as to which the holders of the Outstanding Series B Preferred 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 Series B Preferred Units shall be
deemed to be references to the votes or acts of the Record Holders of such Outstanding Series B Preferred Units. 
 (d) With respect to
Units or Preferred Units that are held for a Person’s account by another Person that is the Record Holder (such as a broker, dealer, bank, trust company or clearing corporation, or an agent of any of the foregoing), such Record Holder shall, in
exercising the voting rights in respect of such Units or Preferred Units on any matter, and unless the arrangement between such Persons provides otherwise, vote such Units or Preferred Units in favor of, and in accordance with the direction of, the
Person who is the beneficial owner of such Units or Preferred Units, and the Partnership shall be entitled to assume such Record Holder is so acting without further inquiry. The provisions of this Section 13.12(d) (as well as all other provisions of
this Agreement) are subject to the provisions of Section 4.3. 

  
 109 

 Section 13.13 Voting of Incentive Distribution Rights. 

(a) For so long as a majority of the Incentive Distribution Rights are held by the General Partner and its Affiliates, the holders of the
Incentive Distribution Rights shall not be entitled to vote such Incentive Distribution Rights on any Partnership matter except as may otherwise be required by law, and the holders of the Incentive Distribution Rights, in their capacity as such,
shall be deemed to have approved any matter approved by the General Partner. 
 (b) For so long as less than a majority of the Incentive
Distribution Rights are held by the General Partner and its Affiliates, the Incentive Distribution Rights will be entitled to vote on all matters submitted to a vote of Unitholders, other than amendments to this Agreement and other matters that the
General Partner determines do not adversely affect the holders of the Incentive Distribution Rights as a whole in any material respect. On any matter in which the holders of Incentive Distribution Rights are entitled to vote, such holders will vote
together with the Subordinated Units, prior to the end of the Subordination Period, or together with the Common Units, thereafter, in either case as a single class except as otherwise required by Section 13.3(c), and such Incentive Distribution
Rights shall be treated in all respects as Subordinated Units or Common Units, as applicable, when sending notices of a meeting of Limited Partners to vote on any matter (unless otherwise required by law), calculating required votes, determining the
presence of a quorum or for other similar purposes under this Agreement. The relative voting power of the Incentive Distribution Rights and the Subordinated Units or Common Units, as applicable, will be set in the same proportion as cumulative cash
distributions, if any, in respect of the Incentive Distribution Rights for the four consecutive Quarters prior to the record date for the vote bears to the cumulative cash distributions in respect of such class of Units for such four Quarters. 

(c) Notwithstanding Section 13.13(b), in connection with any equity financing, or anticipated equity financing, by the Partnership of an
Expansion Capital Expenditure, the General Partner may, without the approval of the holders of the Incentive Distribution Rights, temporarily or permanently reduce the amount of Incentive Distributions that would otherwise be distributed to such
holders, provided that in the judgment of the General Partner, such reduction will be in the long-term best interest of the holders of the Incentive Distribution Rights.

corporations, limited liability companies, statutory trusts or associations, real estate investment trusts, common law trusts or unincorporated businesses, including a partnership (whether general or limited (including a limited liability

 110 

 Section 14.2 Procedure for Merger, Consolidation or Conversion. (a) Merger, consolidation

 Section 14.3 Approval by Limited Partners. Except as provided in Sections 14.3(c) or (d), the General Partner,
upon its approval of the Merger Agreement or the Plan of Conversion, as the case may be, shall direct that the Merger Agreement or the Plan of Conversion, as applicable, be submitted to a vote of Unitholders whether at a special meeting or by
written consent, in either case in accordance with the 

  
 112 

 
requirements of Article XIII. A copy or a summary of the Merger Agreement or the Plan of Conversion, as the case may be, shall be included in or enclosed with the notice of a special meeting or

(a) Except as provided in Section 14.3(c) and Section 14.3(d), the Merger Agreement or Plan of Conversion, as the case may be, shall be
approved upon receiving the affirmative vote or consent of the holders of a Unit Majority unless the Merger Agreement or Plan of Conversion, as the case may be, effects an amendment to any provision of this Agreement that, if contained in an
amendment to this Agreement adopted pursuant to Article XIII, would require for its approval the vote or consent of a greater percentage of the Outstanding Units or of any class of Limited Partners, in which case such greater percentage vote or

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

(d) Additionally, notwithstanding anything else contained in this Article XIV or in this Agreement, the General Partner is permitted, without
Limited Partner approval, to merge or consolidate the Partnership with or into another limited liability entity if (i) the General Partner has received an Opinion of Counsel that the merger or consolidation, as the case may be, would not result in
the loss of the limited liability of any Limited Partner under the laws of the jurisdiction governing the other limited liability entity (if that jurisdiction is not Delaware) as compared to its limited liability under the Delaware Act or cause the
Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes (to the extent not previously treated as such), (ii) the merger or consolidation would

  
 113 

 
not result in an amendment to this Agreement, other than any amendments that could be adopted pursuant to Section 13.1, (iii) the Partnership is the Surviving Business Entity in such merger or
consolidation, (iv) each Unit and Preferred Unit outstanding immediately prior to the effective date of the merger or consolidation is to be an identical Unit or Preferred Unit, as applicable, of the Partnership after the effective date of the

prior to the effective date of such merger or consolidation. 
 (e) Pursuant to Section 17-211(g) of the Delaware Act, an agreement of
merger or consolidation approved in accordance with this Article XIV may (i) effect any amendment to this Agreement or (ii) effect the adoption of a new partnership agreement for the Partnership if it is the Surviving Business Entity. Any such
amendment or adoption made pursuant to this Section 14.3 shall be effective at the effective time or date of the merger or consolidation. 

Section 14.4 Certificate of Merger or Certificate of Conversion. Upon the required approval by the General Partner and the
Unitholders of a Merger Agreement or the Plan of Conversion, as the case may be, a certificate of merger or certificate of conversion or other filing, as applicable, shall be executed and filed with the Secretary of State of the State of Delaware or
the appropriate filing office of any other jurisdiction, as applicable, in conformity with the requirements of the Delaware Act or other applicable law.

property, real, personal and mixed, and all debts due to any of those business entities and all other things and causes of action belonging to each of those business entities, shall be vested in the Surviving Business Entity and after the merger or
consolidation shall be the property of the Surviving Business Entity to the extent they were of each constituent business entity; 

(ii) the title to any real property vested by deed or otherwise in any of those constituent business entities shall not revert
and is not in any way impaired because of the merger or consolidation; 
 (iii) all rights of creditors and all liens on or
security interests in property of any of those constituent business entities shall be preserved unimpaired; and 
 (iv) all
debts, liabilities and duties of those constituent business entities shall attach to the Surviving Business Entity and may be enforced against it to the same extent as if the debts, liabilities and duties had been incurred or contracted by it. 

  
 114 

 (b) At the effective time of the conversion: 

(i) the Partnership shall continue to exist, without interruption, but in the organizational form of the converted entity
rather than in its prior organizational form; 
 (ii) all rights, title, and interests to all real estate and other property
owned by the Partnership shall continue to be owned by the converted entity in its new organizational form without reversion or impairment, without further act or deed, and without any transfer or assignment having occurred, but subject to any
existing liens or other encumbrances thereon; 
 (iii) all liabilities and obligations of the Partnership shall continue to
be liabilities and obligations of the converted entity in its new organizational form without impairment or diminution by reason of the conversion; 

(iv) all rights of creditors or other parties with respect to or against the prior interest holders or other owners of the
Partnership in their capacities as such in existence as of the effective time of the conversion will continue in existence as to those liabilities and obligations and may be pursued by such creditors and obligees as if the conversion did not occur;

 (v) a proceeding pending by or against the Partnership or by or against any of Partners in their capacities as such may be
continued by or against the converted entity in its new organizational form and by or against the prior partners without any need for substitution of parties; and 

(vi) the Partnership Interests that are to be converted into partnership interests, shares, evidences of ownership, or other
securities in the converted entity as provided in the plan of conversion shall be so converted, and Partners shall be entitled only to the rights provided in the Plan of Conversion. 

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 90% of the
total Limited Partner Interests of any class then Outstanding, the General Partner shall then have the right, which right it may assign and transfer in whole or in part to the Partnership or any Affiliate of the General Partner, exercisable at its
option, to purchase all, but not less than all, of such Limited Partner Interests of such class then Outstanding held by Persons other than the General Partner and its Affiliates, at the greater of (x) the Current Market Price as of the date three
Business Days prior to the date that the notice described in Section 15.1(b) is mailed and (y) the highest price paid by the General Partner or any of its Affiliates for any such Limited Partner Interest of such class purchased during the 90-day
period preceding the date that the notice described in Section 15.1(b) is mailed. Notwithstanding the foregoing, if, at any time, the General Partner and its Affiliates hold less 

  
 115 

 
than 70% of the total Limited Partner Interests of any class then Outstanding then, from and after that time, the General Partner’s right set forth in this Section 15.1(a) shall be
exercisable if the General Partner and its Affiliates subsequently hold more than 80% of the total Limited Partner Interests of such class. Notwithstanding the foregoing, the repurchase right described in this Article XV shall not apply to
Series A Preferred Units or Series B Preferred Units. 
 (b) If the General Partner, any Affiliate of the General Partner or the Partnership
elects to exercise the right to purchase Limited Partner Interests granted pursuant to Section 15.1(a), the General Partner shall deliver to the applicable Transfer Agent 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 (as of a Record Date selected by the General Partner), together with
such information as may be required by law, rule or regulation, at least 10, but not more than 60, days prior to the Purchase Date. Such Notice of Election to Purchase shall also be filed and distributed as may be required by the Commission or any
National Securities Exchange on which such Limited Partner Interests are listed. The Notice of Election to Purchase shall specify the Purchase Date and the price (determined in accordance with Section 15.1(a)) at which Limited Partner Interests will
be purchased and state that the General Partner, its Affiliate or the Partnership, as the case may be, elects to purchase such Limited Partner Interests, upon surrender of Certificates representing such Limited Partner Interests, in the case of
Limited Partner Interests evidenced by Certificates, or instructions agreeing to such redemption in exchange for payment, at such office or offices of the Transfer Agent as the Transfer Agent may specify, or as may be required by any National
Securities Exchange on which such Limited Partner Interests are listed. Any such Notice of Election to Purchase mailed to a Record Holder of Limited Partner Interests at his address as reflected in the Register shall be conclusively presumed to have
been given regardless of whether the owner receives such notice. On or prior to the Purchase Date, the General Partner, its Affiliate or the Partnership, as the case may be, shall deposit with the Transfer Agent or exchange agent cash in an amount
sufficient to pay the aggregate purchase price of all of such Limited Partner Interests to be purchased in accordance with this Section 15.1. If the Notice of Election to Purchase shall have been duly given as aforesaid at least 10 days prior to the
Purchase Date, and if on or prior to the Purchase Date the deposit described in the preceding sentence has been made for the benefit of the holders of Limited Partner Interests subject to purchase as provided herein, then from and after the Purchase
Date, notwithstanding that any Certificate or redemption instructions shall not have been surrendered for purchase or provided, respectively, all rights of the holders of such Limited Partner Interests (including any rights pursuant to Article IV,
Article V, Article VI, and Article XII) shall thereupon cease, except the right to receive the purchase price (determined in accordance with Section 15.1(a)) for Limited Partner Interests therefor, without interest, upon surrender to the Transfer
Agent of the Certificates representing such Limited Partner Interests, in the case of Limited Partner Interests evidenced by Certificates, or instructions agreeing to such redemption, and such Limited Partner Interests shall thereupon be deemed to
be transferred to the General Partner, its Affiliate or the Partnership, as the case may be, in the Register, and the General Partner or any Affiliate of the General Partner, or the Partnership, as the case may be, shall be deemed to be the Record
Holder of all such Limited Partner Interests from and after the Purchase Date and shall have all rights as the Record Holder of such Limited Partner Interests (including all rights as owner of such Limited Partner Interests pursuant to Article IV,
Article V, Article VI and Article XII). 
 (c) In the case of Limited Partner Interests evidenced by Certificates, at any time from and
after the Purchase Date, a holder of an Outstanding Limited Partner Interest subject to purchase as provided in this Section 15.1 may surrender his Certificate evidencing such Limited Partner Interest to the Transfer Agent in exchange for payment of
the amount described in Section 15.1(a), therefor, without interest thereon, in accordance with procedures set forth by the General Partner.

 ARTICLE XVI 

SERIES A PERPETUAL PREFERRED UNITS 

Section 16.1 Designation. A series of Preferred Units to be known as “10% Series A Fixed-to-Floating Non-Cumulative
Redeemable Perpetual Preferred Units” is hereby designated and created. Each Series A Preferred Unit shall be identical in all respects to every other Series A Preferred Unit. Each Series A Preferred Unit represents a perpetual equity
interest in the Partnership and shall not give rise to a claim by the holder thereof for payment of a principal amount at any particular date. 

Section 16.2 Series A Preferred Units. 

(a) The authorized number of Series A Preferred Units shall be unlimited. Any Series A Preferred Units that are redeemed, purchased or
otherwise acquired by the Partnership shall be cancelled. 
 (b) The Series A Preferred Units may be evidenced by Certificates in such form
as the General Partner may approve and, subject to the satisfaction of (i) any applicable legal or regulatory requirements and (ii) any applicable contractual requirements governing the transfer by a Series A Holder of Series A Preferred Units, may
be assigned or transferred in a manner identical to the assignment and transfer of other Partnership Interests; unless and until the General Partner determines to assign the responsibility to another Person, the General Partner will act as the
registrar and Transfer Agent for the Series A Preferred Units. Any Certificates evidencing Series A Preferred Units shall be separately identified and shall not bear the same CUSIP number, if any, as the Certificates evidencing Common Units or
Series B Preferred Units. 
 Section 16.3 Distributions. 

(a) Except as otherwise provided herein, distributions on each Series A Preferred Unit shall accrue at the Series A Distribution Rate in each
Quarter from and including the Series A Original Issue Date or the first day of each succeeding Quarter to and including the last day of each such Quarter. Distributions on each Series A Preferred Unit are not mandatory and, in the event
distributions are not declared on Series A Preferred Units for payment for any Quarter, then such distribution shall not be cumulative and shall not accrue and be payable. Subject to the 

  
 117 

 
Delaware Act and other applicable law, Series A Holders shall be entitled to receive Series A Distributions from time to time at the Series A Distribution Rate per Series A Preferred Unit, when,
as, and if declared by the General Partner commencing with the Quarter ending March 31, 2016. Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 16.3, shall be paid each Quarter
on the Series A Distribution Payment Date to Series A Holders on the Record Date selected by the General Partner for the applicable Series A Distribution (the “Series A Distribution Record Date”), and, unless otherwise
determined by the General Partner, shall be deemed to have been paid out of Available Cash with respect to the Quarter immediately preceding the Quarter in which such distribution was made. Series A Distributions for any Quarter in the Fixed Rate
Period shall be payable based on a 360-day year consisting of twelve 30-day months. Series A Distributions for any Quarter in the Floating Rate Period shall be payable based on a 360-day year consisting of twelve 30-day months. All Series A
Distributions payable by the Partnership pursuant to this Section 16.3 shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section
707(c) of the Code. 
 (b) Not later than 5:00 p.m., New York City time, on each Series A Distribution Payment Date, the Partnership shall
pay those Series A Distributions, if any, that shall have been declared by the General Partner to Series A Holders on the Series A Distribution Record Date. So long as the Series A Preferred Units are held of record by the Depositary or a nominee of
the Depositary, declared Series A Distributions shall be paid to the Depositary in same-day funds on each Series A Distribution Payment Date. No distribution shall be declared or paid or set apart for payment on any Junior Securities with respect to
any Quarter unless full distributions have been or contemporaneously are being paid or provided for on all Outstanding Series A Preferred Units and any Parity Securities for such Quarter. If less than all distributions payable with respect to all
Series A Preferred Units and any Parity Securities are paid, any partial payment shall be made pro rata (treating any distributions on Parity Securities paid in units of Parity Securities as being equivalent to a cash payment) with respect to the
Series A Preferred Units and any Parity Securities entitled to a distribution payment at such time in proportion to the aggregate amounts remaining due in respect of such Series A Preferred Units and Parity Securities at such time. No Junior
Securities shall be purchased, redeemed or otherwise acquired for consideration by the Partnership unless full distributions (whether or not such distributions shall have been declared) for each Quarter since the Series A Original Issue Date have
been or contemporaneously are being paid or provided for on all outstanding Series A Preferred Units during any Quarter. 
 (c) LIBOR
for each Quarter during the Floating Rate Period (“Three-Month LIBOR”) shall be determined by the Calculation Agent, as of the applicable LIBOR Determination Date, and shall be the rate (expressed as an annual percentage) for
deposits in U.S. dollars for a three-month period as appears on Bloomberg, L.P. page US0003M, as set by the British Bankers Association at 11:00 a.m. (London time) on such LIBOR Determination Date. If the appropriate page is replaced or service
ceases to be available, the General Partner, acting reasonably, may select another page or service displaying the appropriate rate. 

  
 118 

 Section 16.4 Series A Change of Control. 

(a) Subject to Section 16.4(d), upon the occurrence of a Series A Change of Control that occurs while Series A Preferred Units are
Outstanding, each Series A Holder shall have the right to convert (a “Series A Change of Control Conversion”) such number of Series A Preferred Units held by such Series A Holder on the Series A Change of
Control Conversion Date as such Series A Holder may elect in accordance with Section 16.4(g) into a number of Common Units per Series A Preferred Units that is an amount equal to the Series A Conversion Ratio (such number of Common Units, the
“Series A Common Unit Conversion Consideration”). The “Series A Change of Control Conversion Date” shall be the date fixed by the General Partner, in its sole discretion, as the date the
Series A Preferred Units are to be converted to Conversion Common Units. Such Series A Change of Control Conversion Date shall be a Business Day that is no fewer than 20 days nor more than 35 days from the date on which the Partnership provides the
notice to Series A Holders pursuant to Section 16.4(e). 
 (b) Subject to Section 5.5, the “Series A Conversion
Ratio” shall be calculated as the lesser of: (i) the quotient obtained by dividing (x) the Series A Liquidation Preference as of 5:00 p.m., New York City time, on the Business Day immediately preceding the Series A Change of Control
Conversion Date (unless the Series A Change of Control Conversion Date is after a Record Date for a Series A Distribution and prior to the corresponding payment of such distribution, in which case any such declared and unpaid distribution will be
excluded from this amount) by (y) the Common Unit Price, and (ii) 6.5703 (the “Unit Cap”); provided that the amounts in Section 16.4 (b)(i) and Section 16.4(b)(ii) shall be subject to pro rata adjustments for any Unit splits
(including those effected pursuant to a distribution of Common Units), subdivisions, combinations or distributions (in each case, a “Unit Split”) with respect to Common Units. The adjusted Unit Cap as the result of a Unit
Split will be the number of Common Units that is equal to the product obtained by multiplying (i) the Unit Cap in effect immediately prior to the Unit Split by (ii) a fraction, (a) the numerator of which is the number of Common Units outstanding
after giving effect to the Unit Split and (b) the denominator of which is the number of Common Units outstanding immediately prior to the Unit Split. 

(c) In the case of a Series A Change of Control pursuant to which Common Units will be converted into cash, securities or other property or
assets (including any combination thereof) (“Alternative Conversion Consideration”), each Series A Holder electing to participate in the Series A Change of Control Conversion will receive upon conversion of the Series A
Preferred Units elected by such holder the kind and amount of such Alternative Conversion Consideration on a per Unit basis which such holder would have owned or been entitled to receive upon the Series A Change of Control had such holder held a
number of Common Units equal to the Series A Common Unit Conversion Consideration immediately prior to the effective time of the Series A Change of Control; provided, that, if the holders of Common Units have the opportunity to elect the form of
consideration to be received in such Series A Change of Control, the consideration that the Series A Holders electing to participate in the Series A Change of Control Conversion will receive will be the form and proportion of the aggregate
consideration elected by the holders of Common Units who participate in the determination (based on the weighted average of elections) and will be subject to any limitations to which all holders of Common Units are subject, including, without
limitation, pro rata reductions applicable to any portion of the consideration payable in the Series A Change of Control. No fractional Units will be issued upon the conversion of the Series A Preferred Units. Instead, the Partnership shall pay the
cash value of such fractional Units. 

  
 119 

 (d) Notwithstanding anything to the contrary in this Agreement, if prior to the Series A Change
of Control Conversion Date, a Redeeming Party provides notice of its election to purchase Series A Preferred Units pursuant to Section 16.6 of this Agreement, Series A Holders shall not have any right to convert the Series A Preferred Units that the
Redeeming Party has elected to purchase, and any Series A Preferred Units subsequently selected for purchase that have been tendered for conversion shall be purchased on the Series A Redemption Date instead of converted on the Series A Change of
Control Conversion Date. 
 (e) Within 30 days following the occurrence of a Series A Change of Control, the Partnership (or a third party
with its prior written consent) shall provide to Series A Holders a notice of occurrence of the Series A Change of Control that describes the resulting Series A Change of Control Conversion Right and states: (i) the events constituting the Series A
Change of Control; (ii) the date of the Series A Change of Control; (iii) the Series A Change of Control Conversion Date; (iv) the last date on which the Series A Holders may exercise their Series A Change of Control Conversion Right; (v) the method
and period for calculating the Series A Common Unit Conversion Consideration; (vi) that if, prior to the Series A Change of Control Conversion Date, a Redeeming Party provides notice of its election to purchase Series A Preferred Units pursuant to
Section 16.6 of this Agreement, Series A Holders shall not have any right to convert the Series A Preferred Units that the Redeeming Party has elected to purchase, and any Series A Preferred Units subsequently selected for purchase that have been
tendered for conversion shall be purchased on the Series A Redemption Date instead of converted on the Series A Change of Control Conversion Date; (vii) if applicable, the type and amount of Alternative Conversion Consideration entitled to be
received per Series A Preferred Unit; (viii) the name and address of the Paying Agent; and (ix) the procedures that the Series A Holders must follow to exercise the Series A Change of Control Conversion Right. 

(f) The Partnership (or a third party with its prior written consent) will issue a press release for publication through a news or press
organization that is reasonably expected to broadly disseminate the relevant information to the public, or post notice on the website of the Partnership, in any event prior to the opening of business on the first Business Day following any date on
which the Partnership (or a third party with its prior written consent) provides the notice described above to the Series A Holders. 
 (g)
Each Series A Holder electing to participate in the Series A Change of Control Conversion will be required prior to the close of business on the third Business Day preceding the Series A Change of Control Conversion Date, to notify the Partnership
in writing of the number of Series A Preferred Units held by such Series A Holder on the Series A Change of Control Conversion Date that such holder elects to be converted in the Series A Change of Control Conversion and otherwise to comply with any
applicable procedures of the Depositary for effecting the conversion. The failure of any Series A Holder to timely deliver a written notice in accordance with the immediately preceding sentence (or the delivery by a Series A Holder of a timely
notice of exercise for only a portion, but not all, of the Series A Preferred Units held by such Series A Holder) shall constitute an election by such Series A Holder to not participate in the Series A Change of Control Conversion (or to not
participate in the Series A Change of Control Conversion as to the portion of the Series A Preferred Units held by such Series A Holder as to which a timely notice of exercise was not delivered). 

  
 120 

 (h) Upon conversion, the rights of such participating Series A Holder as a holder of the Series A
Preferred Units shall cease with respect to such converted Series A Preferred Units, and such Person shall continue to be a Partner and have the rights of a holder of Common Units under this Agreement with respect to its Conversion Common Units.
Each Series A Preferred Unit shall, upon its Series A Change of Control Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the issuance of the Conversion Common Units. 

(i) The Partnership shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of
Conversion Common Units. However, the participating Series A Holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of Conversion Common Units in a name other than such Series A
Holder’s name. The Transfer Agent may refuse to reflect the notation of book entry (or the issuance of a Certificate) for Common Units being issued in a name other than the Series A Holder’s name until the Transfer Agent receives a sum
sufficient to pay any tax or duties which will be due because the Common Units are to be issued in a name other than the Series A Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation. 

(j) The Partnership shall comply with all applicable securities laws regulating the offer and delivery of any Conversion Common Units and, if
the Common Units are then listed or quoted on a National Securities Exchange or other market, shall list or cause to have quoted and keep listed and quoted the Conversion Common Units to the extent permitted or required by the rules of such exchange
or market. 
 (k) Notwithstanding anything herein to the contrary, nothing herein shall give to any Series A Holder any rights as a creditor
in respect of its right to conversion. 
 (l) The holder of a Conversion Common Unit shall not be issued a Common Unit Certificate pursuant
to Section 4.1 and shall not be permitted to transfer its Conversion Common Unit to a Person that is not an Affiliate of the holder until such time as the Partnership determines, based on advice of counsel, that a Conversion 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 a Common Unit then Outstanding. In connection with
the condition imposed by this Section 16.4 (l), the Partnership shall take whatever steps are required to provide economic uniformity to the Conversion Common Unit in preparation for a transfer of such Conversion Common Unit, including the
application of Section 6.1(d)(xi); provided, however, that no such steps may be taken that would have a material adverse effect on the Unitholders holding Common Units represented by Common Unit Certificates. 

Section 16.5 Voting Rights. 

(a) Notwithstanding anything to the contrary in this Agreement, the Series A Preferred Units shall have no voting, consent or approval rights
except as set forth in this Section 16.5 or as otherwise required by the Delaware Act. 

  
 121 

 (b) 

(i) Notwithstanding anything to the contrary in this Agreement, unless the Partnership shall have received the affirmative vote
or consent of the holders of at least 66 2⁄3% of the Outstanding Series A Preferred Units, voting as a single class, no amendment to this Agreement shall be
adopted that would or could reasonably be expected to have a material adverse effect on the rights, preferences, obligations or privileges of the Series A Preferred Units. 

(ii) Notwithstanding anything to the contrary in this Agreement, unless the Partnership shall have received the affirmative
vote or consent of the holders of at least 66 2⁄3% of the class composed of the Outstanding Series A Preferred Units and the holders of any other Outstanding
Series B Preferred Units and Outstanding Other Preferred Units, voting as a single class, the Partnership shall not (x) create or issue any Parity Securities (other than Series B Preferred Units or any Other Preferred Units issued upon conversion of
the Series A Preferred Units pursuant to Section 16.12 hereof) with proceeds in an aggregate amount in excess of $700.0 million (y) create or issue any Senior Securities. 

(iii) Notwithstanding anything to the contrary in this Agreement, unless the Partnership shall have (x) received the
affirmative vote or consent of the holders of at least 66 2⁄3% of the class composed of the Outstanding Series A Preferred Units and the holders of any other
Outstanding Series B Preferred Units and Outstanding Other Preferred Units, voting together as a single class, or (y) agreed to purchase the Series A Preferred Units in accordance with Section 16.6, the Partnership shall not effect an Article XIV
Merger; provided that such agreement can be conditioned on the Article XIV Merger. 
 (c) For any matter described in this Section 16.5 in
which the Series A Holders are entitled to vote as a class (whether separately or together with the holders of any Parity Securities), such Series A Holders shall be entitled to one vote per Series A Preferred Unit. 

Section 16.6 Optional Redemption; Redemption Upon a NYSE Event, Series A Change of Control, Article XIV Merger or Rating Event. 

(a) At any time, and from time to time, (v) on or after a NYSE Event with respect to the Series A Preferred Units, (w) on or after February
18, 2021, (x) upon a Series A Change of Control within 120 days after the first date on which such Series A Change of Control occurred, (y) upon an Article XIV Merger within 120 days after the first date on which such Article XIV Merger occurred or
(z) upon the occurrence of, or any time following the occurrence of, a Rating Event, the Partnership or a third party with the prior written consent of the Partnership (such party in clause (v), (w), (x), (y) or (z), as applicable, the
“Redeeming Party”) shall have the right, at its option, subject to the Delaware Act and other applicable law, to purchase the Series A Preferred Units (except with respect to a purchase pursuant to clause (v), for which the
Partnership or a third party must purchase the Series A Preferred Units), in whole or in part (except with respect to a purchase pursuant to clause (v) and (z), for which the Partnership or a 

  
 122 

 
third party must (with respect to clause (v)) or may (with respect to clause (z)) purchase in whole but not in part), from any source of funds legally available for such purpose. Any purchase
pursuant to this Section 16.6 shall be subject to compliance with the provisions of the documents governing the Partnership’s Existing Indebtedness and any other agreements governing the Partnership’s future or existing outstanding
indebtedness. Any such purchase shall occur on a date set by the Redeeming Party (the “Series A Redemption Date”); provided that in the case of clause (v), the Series A Redemption Date shall be no more than 120 days
after the date of occurrence of such NYSE Event. Notwithstanding anything to the contrary herein, (i) the Series A Redemption Date may be on the date of the Series A Change of Control or Article XIV Merger, and any purchase pursuant to this Section
16.6 may be made simultaneously with the Series A Change of Control or Article XIV Merger, as applicable, and (ii) if, pursuant to clause (y) above, the Partnership does not survive such Article XIV Merger, the Series A Redemption Date shall be the
effective date of the Article XIV Merger. 
 (b) Subject to the Delaware Act, the Redeeming Party shall effect any such purchase
pursuant to this Section 16.6 by paying on such Series A Redemption Date cash for each Series A Preferred Unit to be purchased equal to $25.50 per Series A Preferred Unit plus an amount equal to all unpaid distributions thereon (whether or not such
distributions shall have been declared) from the Series A Original Issue Date to the Series A Redemption Date (the “Series A Redemption Price”). So long as the Series A Preferred Units are held of record by the
Depositary or a nominee of the Depositary, the Series A Redemption Price shall be paid by the Paying Agent to the Depositary on the Series A Redemption Date. 

(c) The Redeeming Party shall give notice in accordance with Section 16.9 of its election (or in the case of clause (v) of
Section 16.6(a), its obligation) to purchase Series A Preferred Units pursuant to this Section 16.6 not less than 30 days and not more than 60 days before the scheduled Series A Redemption Date, to the Series A Holders of any Series A Preferred
Units to be purchased as such Series A Holders’ names appear (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) on the books of the Transfer Agent at the address of such Series A Holders
shown therein. Such notice (the “Series A Redemption Notice”) shall state: (i) the Series A Redemption Date, (ii) the number of Series A Preferred Units to be purchased and, if fewer than all Outstanding Series A
Preferred Units are to be purchased, the number (and, in the case of Units in certificated form, the identification) of Units to be purchased from such Series A Holder, (iii) the Series A Redemption Price, (iv) the place where any Series A Preferred
Units in certificated form are to be purchased and shall be presented and surrendered for payment of the Series A Redemption Price therefor, (v) whether the purchase is conditioned upon the consummation of a Series A Change of Control or
Article XIV Merger and (vi) that distributions on the Series A Preferred Units to be purchased shall cease to accumulate from and after such Series A Redemption Date. The Redeeming Party may give the Series A Redemption Notice in advance of a
Series A Change of Control or Article XIV Merger if a definitive agreement is in place for the Series A Change of Control or Article XIV Merger at the time of giving the Series A Redemption Notice and such purchase may be conditioned on
the consummation of the Series A Change of Control or the Article XIV Merger. 
 (d) If the Redeeming Party elects to purchase fewer than
all of the Outstanding Series A Preferred Units pursuant to clause (w), (x) or (y) of Section 16.6 (b), the number of Series A 

  
 123 

 
Preferred Units to be purchased shall be determined by the Redeeming Party, and such Series A Preferred Units shall be purchased by such method of selection as the Depositary (or, in the case of
any certificated Series A Preferred Units, the General Partner) shall determine, either Pro Rata or by lot, with adjustments to avoid purchase of fractional Series A Preferred Units. So long as all Series A Preferred Units are held of record by the
Depositary or a nominee of the Depositary, the Redeeming Party shall give notice, or cause notice to be given, to the Depositary of the number of Series A Preferred Units to be purchased, and the Depositary shall determine the number of Series A
Preferred Units to be purchased from the account of each of its participants holding such Series A Preferred Units in its participant account. Thereafter, each participant shall select the number of Series A Preferred Units to be purchased from each
such beneficial owner for whom it acts (including the participant, to the extent it holds Series A Preferred Units for its own account). The Series A Preferred Units not purchased shall remain Outstanding and entitled to all the rights and
preferences provided in this Article XVI. 
 (e) If the Redeeming Party gives a Series A Redemption Notice, the Redeeming Party shall
deposit with the Paying Agent funds sufficient to purchase the Series A Preferred Units as to which such Series A Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series A Redemption Date, and the Redeeming
Party shall give the Paying Agent irrevocable instructions and authority to pay the Series A Redemption Price to the Series A Holders to be purchased upon surrender or deemed surrender (which shall occur automatically if the Certificate representing
such Series A Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series A Redemption Notice. If the Series A Redemption Notice shall have been given, then from and after the
Series A Redemption Date, unless the Redeeming Party defaults in providing funds sufficient for such purchase at the time and place specified for payment pursuant to the Series A Redemption Notice or, unless the purchase is conditioned on the Series
A Change of Control or the Article XIV Merger and such Series A Change of Control or Article XIV Merger does not occur, all Series A Distributions on such Series A Preferred Units to be purchased shall cease to accumulate and all rights of holders
of such Series A Preferred Units with respect to such Series A Preferred Units shall cease, except the right to receive the Series A Redemption Price, including any amount equal to accumulated and unpaid distributions to the Series A Redemption Date
(whether or not declared), and such Series A Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Redeeming Party shall be entitled to receive from the
Paying Agent the interest income, if any, earned on such funds deposited with the Paying Agent (to the extent that such interest income is not required to pay the Series A Redemption Price of the Series A Preferred Units to be purchased), and the
holders of any Series A Preferred Units so purchased shall have no claim to any such interest income. Any funds deposited with the Paying Agent hereunder by the Redeeming Party for any reason, including purchase of Series A Preferred Units, that
remain unclaimed or unpaid after two years after the applicable Series A Redemption Date or other payment date, shall be, to the extent permitted by law, repaid to the Redeeming Party upon its written request, after which repayment the Series A
Holders entitled to such purchase or other payment shall have recourse only to the Redeeming Party. Notwithstanding any Series A Redemption Notice, there shall be no purchase of any Series A Preferred Units called for purchase until funds sufficient
to pay the full Series A Redemption Price of such Series A Preferred Units shall have been deposited by the Redeeming Party with the Paying Agent. 

(f) Any Series A Preferred Units that are purchased or otherwise acquired by the Redeeming Party shall be canceled. If only a portion of the
Series A Preferred Units represented by a Certificate shall have been called for purchase, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series A Preferred Units is
registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series A Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series A
Preferred Units represented by the surrendered Certificate that have not been called for purchase. 

  
 124 

 Section 16.7 No Sinking Fund. The Series A Preferred Units shall not have the benefit of
any sinking fund. 
 Section 16.8 Record Holders. To the fullest extent permitted by applicable law, the Partnership, the Transfer
Agent and the Paying Agent may deem and treat any Series A Holder as the true, lawful and absolute owner of the applicable Series A Preferred Units for all purposes, and, to the fullest extent permitted by law, neither the Partnership, the Transfer
Agent nor the Paying Agent shall be affected by any notice to the contrary. 
 Section 16.9 Notices. All notices or other
communications in respect of the Series A Preferred Units shall be sufficiently given (i) if given in writing in the English language and either delivered in person or sent by first class mail, postage prepaid at the address shown in the Register
for each Series A Holder or, in the case of the initial Series A Holder, the address set forth below:

 Section 16.10 Other Rights; Liquidation Preference. 

The Series A Preferred Units shall not have any voting powers, preferences or relative, participating, optional or other special rights, or
qualifications, limitations or restrictions thereof, other than as set forth in this Article XVI or as required by applicable law. Notwithstanding anything to the contrary in this Agreement, but subject to the Delaware Act and other applicable law,
in the event of any liquidation, dissolution or winding up of the Partnership or the sale or disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders holding Preferred Units shall
be entitled to be paid, or have the Partnership declare and set apart for payment, 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 Junior Securities, any unpaid Series A Distributions and the positive value in each such Record Holder’s Capital Account in respect of such Series A Preferred Units. 

Section 16.11 Reserved.  

Section 16.12 Series A Non-Affiliate Transfers; Conversion to Series B Preferred Units or Other Preferred Units. 

(a) Any Series A Preferred Units (i) held by a Series A Non-Affiliate on the day immediately following the second anniversary of the Series A
Original Issue Date or (ii) acquired by a Series A Non-Affiliate pursuant to a Series A Non-Affiliate Transfer after the second anniversary of the Series A Original Issue Date (such dates in clauses (i) and (ii), a “Series B Conversion
Date”) shall automatically, on such Series B Conversion Date subject to Section 16.12(e), without any action by such Series A Non-Affiliate, convert into a number of Series B Preferred Units equal to the number of Series A Preferred
Units held or acquired, as applicable, by such Series A Non-Affiliate on such Series B Conversion Date (a “Series A Non-Affiliate Conversion”). Such Series B Preferred Units shall have the terms, rights and preferences as set
forth in Article XVII. No Series A Preferred Units shall be converted to Series B Preferred Units prior to a Series B Conversion Date and other than pursuant to this Section 16.12. 

(b) A Series A Holder shall deliver as promptly as practicable written notice to the Partnership of any Series A Non-Affiliate Transfer
identifying the transferee, the address of the transferee, the number of Series A Preferred Units transferred and the date of the transfer. 

(c) In the event of a Series A Non-Affiliate Conversion, the Partnership shall deliver as promptly as practicable written notice to each
Series A Non-Affiliate specifying: (i) the Series B Conversion Date, (ii) the number of Series B Preferred Units to be issued in respect of each Series A Preferred Unit that is converted and (iii) the place or places where certificates for such
Series A Preferred Units are to be surrendered for issuance of certificates representing Series B Preferred Units. Each certificate representing a Series A Preferred Unit surrendered in a Series A Non-Affiliate Conversion shall be accompanied by
instruments of transfer, in form satisfactory to the Partnership, duly executed by the Series A Transferor or such transferor’s duly authorized attorney and an amount sufficient to pay any transfer or similar tax in accordance with Section
4.5(b). 

  
 126 

 (d) Any Series A Non-Affiliate Conversion shall be deemed to have been effected at the close of
business on the applicable Series B Conversion Date. At such time: (i) the Series A Non-Affiliate in whose name any certificate or certificates for Series B Preferred Units shall be issuable upon such Series A Non-Affiliate Conversion shall be
deemed to have become the Record Holder of the Series B Preferred Units represented thereby at such time; (ii) such Series A Preferred Units so converted shall no longer be deemed to be outstanding, and (iii) if the Series A Non-Affiliate Conversion
is a result of a Series A Non-Affiliate Transfer, all rights of the Series A Transferor with respect to such Series A Preferred Units shall immediately terminate; provided, however, (A) that if such Series A Non-Affiliate Transfer occurs after a
Series A Distribution Record Date but before the corresponding Series A Distribution Payment Date, such Series A Transferor shall be entitled to any Series A Distributions on such Series A Preferred Units paid on such Series A Distribution Payment
Date, and (B) if such Series A Non-Affiliate Transfer occurs before a Series A Distribution Record Date, any Series A Non-Affiliate transferee who holds Series B Preferred Units as a result of such Series A Non-Affiliate Conversion on the Series A
Distribution Record Date shall be entitled to any Series A Distribution on such Series A Preferred Units payable on such Series A Distribution Payment Date as a result of the fact that such Series B Distributions shall accrue from the immediately
preceding Quarter in accordance with Section 17.3(a)(ii). 
 (e) Notwithstanding Section 16.12(a), each time that (i) the Partnership is
required to issue Series B Preferred Units pursuant to this Section 16.12 (such issuance, a “New Series B Issuance”), (ii) other Series B Preferred Units previously issued pursuant to this Section 16.12 remain Outstanding and
(iii) at the time of the New Series B Issuance, the Partnership is in Arrears with respect to any previously issued Series B Preferred Units, then the General Partner shall (a) adopt an amendment to this Agreement to provide for a new series of
Preferred Units (the “Other Preferred Units”), such Other Preferred Units to have the same rights and preferences as the Series B Preferred Units except that the distributions for such Other Preferred Units will accumulate
from the date of issuance of such Other Preferred Units and (b) in lieu of issuing Series B Preferred Units in the New Series B Issuance, the Partnership shall issue Other Preferred Units in an amount equal to the number of Series B Preferred Units
that would have otherwise been issued in such New Series B Issuance pursuant to Section 16.12(a). Any Other Preferred Units to be issued pursuant to any amendment to the Agreement pursuant to this Section 16.12(e) shall be Parity Securities.

 ARTICLE XVII 

SERIES B PERPETUAL PREFERRED UNITS 

Section 17.1 Designation. A series of Preferred Units to be known as “10% Series B Fixed-to-Floating Cumulative Redeemable
Perpetual Preferred Units” is hereby designated and created. Each Series B Preferred Unit shall be identical in all respects to every other Series B Preferred Unit, except as to the respective dates from which Series B Distributions may
begin accruing, to the 

  
 127 

 
extent such dates may differ. Each Series B Preferred Unit represents a perpetual equity interest in the Partnership and shall not give rise to a claim by the holder thereof for payment of a
principal amount at any particular date. 
 Section 17.2 Series B Preferred Units. 

(a) The authorized number of Series B Preferred Units shall be unlimited. Any Series B Preferred Units that are redeemed, purchased or
otherwise acquired by the Partnership shall be cancelled. 
 (b) The Series B Preferred Units may be evidenced by Certificates in such form
as the General Partner may approve and, subject to the satisfaction of (i) any applicable legal or regulatory requirements and (ii) any applicable contractual requirements governing the transfer by a Series B Holder of Series B Preferred Units, may
be assigned or transferred in a manner identical to the assignment and transfer of other Partnership Interests; unless and until the General Partner determines to assign the responsibility to another Person, the General Partner will act as the
registrar and Transfer Agent for the Series B Preferred Units. Any Certificates evidencing Series B Preferred Units shall be separately identified and shall not bear the same CUSIP number, if any, as the Certificates evidencing Common Units or
Series A Preferred Units. 
 Section 17.3 Distributions. 

(a) Except as otherwise provided herein, distributions on each Series B Preferred Unit shall be cumulative and shall accrue at the Series B
Distribution Rate in each Quarter from and including (i) the first day of the Quarter in which the applicable Series B Conversion Date for such Series B Preferred Unit occurs, if such Series B Conversion Date occurs after the Series B Distribution
Record Date for the immediately preceding Quarter or, in the case of the first Series B Conversion Date, the Series A Distribution Record Date for the immediately preceding Quarter or (ii) the first day of the Quarter immediately preceding the
Quarter in which the applicable Series B Conversion Date for such Series B Preferred Unit occurs, if such Series B Conversion Date occurs before the Series B Distribution Record Date for such preceding Quarter or, in the case of the first Series B
Conversion Date, the Series A Distribution Record Date for such preceding Quarter, and in each case, to and including the last day of each succeeding Quarter, until such time as the Partnership (or, in the case of Section 17.6, any Redeeming Party)
pays the Series B Distribution or converts all of the Outstanding Series B Preferred Units in accordance with Section 17.4 or a Redeeming Party purchases all of the Outstanding Series B Preferred Units in accordance with Section 17.6, whether or not
such Series B Distributions shall have been declared, and distributions shall accumulate on the amount of Series B Distributions in Arrears at the Series B Distribution Rate. Subject to the Delaware Act and other applicable law, Series B
Holders shall be entitled to receive Series B Distributions from time to time at the Series B Distribution Rate per Series B Preferred Unit, when, as, and if declared by the General Partner. Distributions, to the extent declared by the General
Partner to be paid by the Partnership 

  
 128 

 
in accordance with this Section 17.3, shall be paid each Quarter on the Series B Distribution Payment Date to Series B Holders on the Record Date selected by the General Partner for the
applicable Series B Distribution (the “Series B Distribution Record Date”) (except that in the case of payments of Series B Distributions in Arrears, the Series B Distribution Record Date with respect to such payment shall be
such date as may be designated by the General Partner in accordance with this Article XVII), and, unless otherwise determined by the General Partner, shall be deemed to have been paid out of Available Cash with respect to the Quarter immediately
preceding the Quarter in which such distribution was made. Series B Distributions for any Quarter in the Fixed Rate Period shall be payable based on a 360-day year consisting of twelve 30-day months. Series B Distributions for any Quarter in the
Floating Rate Period shall be payable based on a 360-day year consisting of twelve 30-day months. All Series B Distributions payable by the Partnership pursuant to this Section 17.3 shall be payable without regard to income of the Partnership and
shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. Except in the case of payments of Series B Distributions in Arrears, each Series B Distribution Record Date will be the
same as each Series A Distribution Date, if any. 
 (b) Not later than 5:00 p.m., New York City time, on each Series B Distribution Payment
Date, the Partnership shall pay those Series B Distributions, if any, that shall have been declared by the General Partner to Series B Holders on the Series B Distribution Record Date. In the case of payments of Series B Distributions in Arrears,
the Series B Distribution Record Date with respect to such payment shall be such date as may be designated by the General Partner in accordance with this Article XVII. So long as the Series B Preferred Units are held of record by the Depositary or a
nominee of the Depositary, declared Series B Distributions shall be paid to the Depositary in same-day funds on each Series B Distribution Payment Date or other distribution payment date in the case of payments for Series B Distributions in Arrears.
No distribution shall be declared or paid or set apart for payment on any Junior Securities with respect to any Quarter unless full cumulative distributions (whether or not such distributions shall have been declared) have been or contemporaneously
are being paid or provided for on all Outstanding Series B Preferred Units and any Parity Securities through such Quarter. No Junior Securities shall be purchased, redeemed or otherwise acquired for consideration by the Partnership unless full
cumulative distributions (whether or not such distributions shall have been declared) through such Quarter have been or contemporaneously are being paid or provided for on all outstanding Series B Preferred Units during any Quarter. Accumulated
Series B Distributions in Arrears for any past Quarter may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series B Distribution Payment Date, to Series B Holders on the record date for such
payment, which may not be less than 10 days nor more than 60 days before such payment date. Subject to the next succeeding sentence, if all accumulated Series B Distributions in Arrears on all Outstanding Series B Preferred Units and any Parity
Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears shall be made in order of their respective distribution payment dates,
commencing with the earliest. If less than all distributions payable with respect to all Series B Preferred Units and any Parity Securities are paid, any partial payment shall be made pro rata (treating any distributions on Parity Securities paid in
units of Parity Securities as being equivalent to a cash payment) with respect to the Series B Preferred Units and any Parity Securities entitled to a distribution payment at such time in proportion to the aggregate amounts remaining due in respect
of such Series B Preferred Units and Parity Securities at such time. 
 (c) The Three-Month LIBOR shall be determined by the Calculation
Agent, as of the applicable LIBOR Determination Date, and shall be the rate (expressed as an annual percentage) for deposits in U.S. dollars for a three-month period as appears on Bloomberg, L.P. page US0003M, as set by the British Bankers
Association at 11:00 a.m. (London time) on such LIBOR Determination Date. If the appropriate page is replaced or service ceases to be available, the General Partner, acting reasonably, may select another page or service displaying the appropriate
rate. 

  
 129 

 Section 17.4 Series B Change of Control. 

(a) Subject to Section 17.4(d), upon the occurrence of a Series B Change of Control that occurs while Series B Preferred Units are
Outstanding, each Series B Holder shall have the right to convert (a “Series B Change of Control Conversion”) such number of Series B Preferred Units held by such Series B Holder on the Series B Change of
Control Conversion Date as such Series B Holder may elect in accordance with Section 17.4(g) into a number of Common Units per Series B Preferred Units that is an amount equal to the Series B Conversion Ratio (such number of Common Units, the
“Series B Common Unit Conversion Consideration”). The “Series B Change of Control Conversion Date” shall be the date fixed by the General Partner, in its sole discretion, as the date the
Series B Preferred Units are to be converted to Conversion Common Units. Such Series B Change of Control Conversion Date shall be a Business Day that is no fewer than 20 days nor more than 35 days from the date on which the Partnership provides the
notice to Series B Holders pursuant to Section 17.4 (e). 
 (b) Subject to Section 5.5, the “Series B Conversion
Ratio” shall be calculated as the lesser of: (i) the quotient obtained by dividing (x) the Series B Liquidation Preference as of 5:00 p.m., New York City time, on the Business Day immediately preceding the Series B Change of Control
Conversion Date (unless the Series B Change of Control Conversion Date is after a Record Date for a Series B Distribution and prior to the corresponding payment of such distribution, in which case any such declared and unpaid distribution will be
excluded from this amount) by (y) the Common Unit Price, and (ii) the Unit Cap; provided that the amounts in Section 17.4(b)(i) and Section 17.4(b)(ii) shall be subject to pro rata adjustments for any Unit Splits with respect to Common Units. The
adjusted Unit Cap as the result of a Unit Split will be the number of Common Units that is equal to the product obtained by multiplying (i) the Unit Cap in effect immediately prior to the Unit Split by (ii) a fraction, (a) the numerator of which is
the number of Common Units outstanding after giving effect to the Unit Split and (b) the denominator of which is the number of Common Units outstanding immediately prior to the Unit Split. 

(c) In the case of a Series B Change of Control pursuant to which Common Units will be converted into Alternative Conversion Consideration,
each Series B Holder electing to participate in the Series B Change of Control Conversion will receive upon conversion of the Series B Preferred Units elected by such holder the kind and amount of such Alternative

  
 130 

 
Conversion Consideration on a per Unit basis which such holder would have owned or been entitled to receive upon the Series B Change of Control had such holder held a number of Common Units equal
to the Series B Common Unit Conversion Consideration immediately prior to the effective time of the Series B Change of Control; provided, that, if the holders of Common Units have the opportunity to elect the form of consideration to be received in
such Series B Change of Control, the consideration that the Series B Holders electing to participate in the Series B Change of Control Conversion will receive will be the form and proportion of the aggregate consideration elected by the holders of
Common Units who participate in the determination (based on the weighted average of elections) and will be subject to any limitations to which all holders of Common Units are subject, including, without limitation, pro rata reductions applicable to
any portion of the consideration payable in the Series B Change of Control. No fractional Units will be issued upon the conversion of the Series B Preferred Units. Instead, the Partnership shall pay the cash value of such fractional Units. 

(d) Notwithstanding anything to the contrary in this Agreement, if prior to the Series B Change of Control Conversion Date, a Redeeming Party
provides notice of its election to purchase Series B Preferred Units pursuant to Section 17.6 of this Agreement, Series B Holders shall not have any right to convert the Series B Preferred Units that the Redeeming Party has elected to purchase, and
any Series B Preferred Units subsequently selected for purchase that have been tendered for conversion shall be purchased on the Series B Redemption Date instead of converted on the Series B Change of Control Conversion Date. 

(e) Within 30 days following the occurrence of a Series B Change of Control, the Partnership (or a third party with its prior written consent)
shall provide to Series B Holders a notice of occurrence of the Series B Change of Control that describes the resulting Series B Change of Control Conversion Right and states: (i) the events constituting the Series B Change of Control; (ii) the date
of the Series B Change of Control; (iii) the Series B Change of Control Conversion Date; (iv) the last date on which the Series B Holders may exercise their Series B Change of Control Conversion Right; (v) the method and period for calculating the
Series B Common Unit Conversion Consideration; (vi) that if, prior to the Series B Change of Control Conversion Date, a Redeeming Party provides notice of its election to purchase Series B Preferred Units pursuant to Section 17.6 of this Agreement,
Series B Holders shall not have any right to convert the Series B Preferred Units that the Redeeming Party has elected to purchase, and any Series B Preferred Units subsequently selected for purchase that have been tendered for conversion shall be
purchased on the Series B Redemption Date instead of converted on the Series B Change of Control Conversion Date; (vii) if applicable, the type and amount of Alternative Conversion Consideration entitled to be received per Series B Preferred Unit;
(viii) the name and address of the Paying Agent; and (ix) the procedures that the Series B Holders must follow to exercise the Series B Change of Control Conversion Right. 

(f) The Partnership (or a third party with its prior written consent) will issue a press release for publication through a news or press
organization that is reasonably expected to broadly disseminate the relevant information to the public, or post notice on the website of the Partnership, in any event prior to the opening of business on the first Business Day following any date on
which the Partnership (or a third party with its prior written consent) provides the notice described above to the Series B Holders. 

  
 131 

 (g) Each Series B Holder electing to participate in the Series B Change of Control Conversion
will be required prior to the close of business on the third Business Day preceding the Series B Change of Control Conversion Date, to notify the Partnership in writing of the number of Series B Preferred Units held by such Series B Holder on the
Series B Change of Control Conversion Date that such holder elects to be converted in the Series B Change of Control Conversion and otherwise to comply with any applicable procedures of the Depositary for effecting the conversion. The failure of any
Series B Holder to timely deliver a written notice in accordance with the immediately preceding sentence (or the delivery by a Series B Holder of a timely notice of exercise for only a portion, but not all, of the Series B Preferred Units held by
such Series B Holder) shall constitute an election by such Series B Holder to not participate in the Series B Change of Control Conversion (or to not participate in the Series B Change of Control Conversion as to the portion of the Series B
Preferred Units held by such Series B Holder as to which a timely notice of exercise was not delivered). 
 (h) Upon conversion, the rights
of such participating Series B Holder as a holder of the Series B Preferred Units shall cease with respect to such converted Series B Preferred Units, and such Person shall continue to be a Partner and have the rights of a holder of Common Units
under this Agreement with respect to its Conversion Common Units. Each Series B Preferred Unit shall, upon its Series B Change of Control Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the issuance
of the Conversion Common Units. 
 (i) The Partnership shall pay any documentary, stamp or similar issue or transfer taxes or duties
relating to the issuance or delivery of Conversion Common Units. However, the participating Series B Holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of Conversion Common Units in a
name other than such Series B Holder’s name. The Transfer Agent may refuse to reflect the notation of book entry (or the issuance of a Certificate) for Common Units being issued in a name other than the Series B Holder’s name until the
Transfer Agent receives a sum sufficient to pay any tax or duties which will be due because the Common Units are to be issued in a name other than the Series B Holder’s name. Nothing herein shall preclude any tax withholding required by law or
regulation. 
 (j) The Partnership shall comply with all applicable securities laws regulating the offer and delivery of any Conversion
Common Units and, if the Common Units are then listed or quoted on a National Securities Exchange or other market, shall list or cause to have quoted and keep listed and quoted the Conversion Common Units to the extent permitted or required by the
rules of such exchange or market. 
 (k) Notwithstanding anything herein to the contrary, nothing herein shall give to any Series B Holder
any rights as a creditor in respect of its right to conversion. 
 (l) The holder of a Conversion Common Unit shall not be issued a Common
Unit Certificate pursuant to Section 4.1 and shall not be permitted to transfer its Conversion Common Unit to a Person that is not an Affiliate of the holder until such time as the Partnership determines, based on advice of counsel, that a
Conversion 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 a

  
 132 

 
Common Unit then Outstanding. In connection with the condition imposed by this Section 17.4(l), the Partnership shall take whatever steps are required to provide economic uniformity to the
Conversion Common Unit in preparation for a transfer of such Conversion Common Unit, including the application of Section 6.1(d)(xi); provided, however, that no such steps may be taken that would have a material adverse effect on the
Unitholders holding Common Units represented by Common Unit Certificates. 
 Section 17.5 Voting Rights. 

(a) Notwithstanding anything to the contrary in this Agreement, the Series B Preferred Units shall have no voting, consent or approval rights
except as set forth in this Section 17.5 or as otherwise required by the Delaware Act. 
 (b) 

(i) Notwithstanding anything to the contrary in this Agreement, unless the Partnership shall have received the affirmative vote
or consent of the holders of at least 66 2⁄3% of the Outstanding Series B Preferred Units, voting as a single class, no amendment to this Agreement shall be
adopted that would or could reasonably be expected to have a material adverse effect on the rights, preferences, obligations or privileges of the Series B Preferred Units. 

(ii) Notwithstanding anything to the contrary in this Agreement, unless the Partnership shall have received the affirmative
vote or consent of the holders of at least 66 2⁄3% of the class composed of the Outstanding Series B Preferred Units and the holders of any other Outstanding
Series A Preferred Units and Outstanding Other Preferred Units, voting as a single class, the Partnership shall not (x) create or issue any Parity Securities (other than Series B Preferred Units or any Other Preferred Units issued upon conversion of
the Series A Preferred Units pursuant to Section 16.12 hereof) with proceeds in an aggregate amount in excess of $700.0 million (y) create or issue any Senior Securities. 

(iii) Notwithstanding anything to the contrary in this Agreement, unless the Partnership shall have (x) received the
affirmative vote or consent of the holders of at least 66 2⁄3% of the class composed of the Outstanding Series B Preferred Units and the holders of the
Outstanding Series A Preferred Units and Outstanding Other Preferred Units, voting together as a single class, or (y) agreed to purchase the Series B Preferred Units in accordance with Section 17.6, the Partnership shall not effect an Article XIV
Merger; provided that such agreement can be conditioned on the Article XIV Merger. 
 (c) For any matter described in this Section 17.5 in
which the Series B Holders are entitled to vote as a class with the Series A Preferred Units, such Series B Holders shall be entitled to one vote per Series B Preferred Unit.

 Section 17.6 Optional Redemption; Redemption Upon a NYSE Event, Series B Change of Control,
Article XIV Merger, Fungibility Event or Rating Event. 
 (a) At any time, and from time to time, (v) on or after a NYSE Event with
respect to the Series B Preferred Units or a Fungibility Event, (w) on or after February 18, 2021, (x) upon a Series B Change of Control within 120 days after the first date on which such Series B Change of Control occurred, (y) upon an Article XIV
Merger within 120 days after the first date on which such Article XIV Merger occurred or (z) upon the occurrence of, or any time following the occurrence of, a Rating Event, the Partnership or a Redeeming Party shall have the right, at its
option, subject to the Delaware Act and other applicable law, to purchase the Series B Preferred Units (except with respect to a purchase pursuant to clause (v), for which the Partnership or a third party must purchase the Series B Preferred
Units), in whole or in part (except with respect to a purchase pursuant to clause (v) and (z), for which the Partnership or a third party must (with respect to clause (v)) or may (with respect to clause (z)) purchase in whole but not in part), from
any source of funds legally available for such purpose. Any purchase pursuant to this Section 17.6 shall be subject to compliance with the provisions of the documents governing the Partnership’s Existing Indebtedness and any other agreements
governing the Partnership’s future or existing outstanding indebtedness. Any such purchase shall occur on a date set by the Redeeming Party, (the “Series B Redemption Date”); provided that in the case of clause (v), the
Series B Redemption Date shall be no more than 120 days after the date of occurrence of such NYSE Event or such Fungibility Event. Notwithstanding anything to the contrary herein, (i) the Series B Redemption Date may be on the date of the Series B
Change of Control or Article XIV Merger, and any purchase pursuant to this Section 17.6 may be made simultaneously with the Series B Change of Control or Article XIV Merger, as applicable, and (ii) if, pursuant to clause (y) above, the Partnership
does not survive such Article XIV Merger, the Series B Redemption Date shall be the effective date of the Article XIV Merger. 
 (b) Subject
to the Delaware Act, the Redeeming Party shall effect any such purchase pursuant to this Section 17.6 by paying on such Series B Redemption Date cash for each Series B Preferred Unit to be purchased equal to $25.50 per Series B Preferred Unit plus
an amount equal to all accumulated and unpaid distributions thereon (whether or not such distributions shall have been declared) from the Series A Original Issue Date through the Series B Redemption Date (the “Series B Redemption
Price”). So long as the Series B Preferred Units are held of record by the Depositary or a nominee of the Depositary, the Series B Redemption Price shall be paid by the Paying Agent to the Depositary on the Series B Redemption
Date. 
 (c) The Redeeming Party shall give notice in accordance with Section 17.9 of its election (or in the case of clause (v) of
Section 17.6(a), its obligation) to purchase Series B Preferred Units pursuant to this Section 17.6 not less than 30 days and not more than 60 days before the scheduled Series B Redemption Date, to the Series B Holders of any Series B Preferred
Units to be purchased as such Series B Holders’ names appear (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) on the books of the Transfer Agent at the address of such Series B Holders
shown therein. Such notice (the “Series B Redemption Notice”) shall state: (i) the Series B Redemption Date, (ii) the number of Series B Preferred Units to be purchased and, if fewer than all Outstanding Series B
Preferred Units are to be purchased, the number (and, in the case of Units in certificated form, the identification) of Units to be purchased from such Series B Holder, (iii) the Series B Redemption Price, (iv) the place where any Series B Preferred
Units in certificated form are to 

  
 134 

 
be purchased and shall be presented and surrendered for payment of the Series B Redemption Price therefor, (v) whether the purchase is conditioned on the consummation of a Series B Change of
Control or Article XIV Merger and (vi) that distributions on the Series B Preferred Units to be purchased shall cease to accumulate from and after such Series B Redemption Date. The Redeeming Party may give the Series B Redemption Notice in
advance of a Series B Change of Control or Article XIV Merger if a definitive agreement is in place for the Series B Change of Control or Article XIV Merger at the time of giving the Series B Redemption Notice and such purchase may be conditioned on
the consummation of the Series B Change of Control or the Article XIV Merger. 
 (d) If the Redeeming Party elects to purchase fewer than
all of the Outstanding Series B Preferred Units pursuant to clause (w), (x) or (y) of Section 17.6(b), the number of Series B Preferred Units to be purchased shall be determined by the Redeeming Party, and such Series B Preferred Units shall be
purchased by such method of selection as the Depositary (or, in the case of any certificated Series B Preferred Units, the General Partner) shall determine, either Pro Rata or by lot, with adjustments to avoid purchase of fractional Series B
Preferred Units. So long as all Series B Preferred Units are held of record by the Depositary or a nominee of the Depositary, the Redeeming Party shall give notice, or cause notice to be given, to the Depositary of the number of Series B
Preferred Units to be purchased, and the Depositary shall determine the number of Series B Preferred Units to be purchased from the account of each of its participants holding such Series B Preferred Units in its participant account. Thereafter,
each participant shall select the number of Series B Preferred Units to be purchased from each such beneficial owner for whom it acts (including the participant, to the extent it holds Series B Preferred Units for its own account). The Series B
Preferred Units not purchased shall remain Outstanding and entitled to all the rights and preferences provided in this Article XVI. 
 (e)
If the Redeeming Party gives a Series B Redemption Notice, the Redeeming Party shall deposit with the Paying Agent funds sufficient to purchase the Series B Preferred Units as to which such Series B Redemption Notice shall have been given, no later
than 10:00 a.m. New York City time on the Series B Redemption Date, and the Redeeming Party shall give the Paying Agent irrevocable instructions and authority to pay the Series B Redemption Price to the Series B Holders to be purchased upon
surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series B Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series B Redemption
Notice. If the Series B Redemption Notice shall have been given, then from and after the Series B Redemption Date, unless the Redeeming Party defaults in providing funds sufficient for such purchase at the time and place specified for payment
pursuant to the Series B Redemption Notice or, unless the purchase is conditioned on the Series B Change of Control or the Article XIV Merger and such Series B Change of Control or Article XIV Merger does not occur, all Series B Distributions on
such Series B Preferred Units to be purchased shall cease to accumulate and all rights of holders of such Series B Preferred Units with respect to such Series B Preferred Units shall cease, except the right to receive the Series B Redemption Price,
including any amount equal to accumulated and unpaid distributions to the Series B Redemption Date (whether or not declared), and such Series B Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed
to be Outstanding for any purpose whatsoever. The Redeeming Party shall be entitled to receive from the Paying Agent the interest income, if any, earned on such funds deposited with the Paying Agent (to the extent that such interest income is not

  
 135 

 
required to pay the Series B Redemption Price of the Series B Preferred Units to be purchased), and the holders of any Series B Preferred Units so purchased shall have no claim to any such
interest income. Any funds deposited with the Paying Agent hereunder by the Redeeming Party for any reason, including purchase of Series B Preferred Units, that remain unclaimed or unpaid after two years after the applicable Series B Redemption Date
or other payment date, shall be, to the extent permitted by law, repaid to the Redeeming Party upon its written request, after which repayment the Series B Holders entitled to such purchase or other payment shall have recourse only to the Redeeming
Party. Notwithstanding any Series B Redemption Notice, there shall be no purchase of any Series B Preferred Units called for purchase until funds sufficient to pay the full Series B Redemption Price of such Series B Preferred Units shall have been
deposited by the Redeeming Party with the Paying Agent. 
 (f) Any Series B Preferred Units that are purchased or otherwise acquired by the
Redeeming Party shall be canceled. If only a portion of the Series B Preferred Units represented by a Certificate shall have been called for purchase, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the
Certificate representing such Series B Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series B Holders a new Certificate (or adjust the applicable
book-entry account) representing the number of Series B Preferred Units represented by the surrendered Certificate that have not been called for purchase. 

Section 17.7 No Sinking Fund. The Series B Preferred Units shall not have the benefit of any sinking fund. 

Section 17.8 Record Holders. To the fullest extent permitted by applicable law, the Partnership, the Transfer Agent and the Paying
Agent may deem and treat any Series B Holder as the true, lawful and absolute owner of the applicable Series B Preferred Units for all purposes, and, to the fullest extent permitted by law, neither the Partnership, the Transfer Agent nor the Paying
Agent shall be affected by any notice to the contrary. 
 Section 17.9 Notices. All notices or other communications in respect
of the Series B Preferred Units shall be sufficiently given (i) if given in writing in the English language and either delivered in person or sent by first class mail, postage prepaid at the address shown in the Register for each Series B Holder, or
(ii) if given in such other manner as may be permitted in this Article XVII, this Agreement or by applicable law. Any notice or other communication given to a holder of a Series B Preferred Unit in book-entry form shall be given in the manner
prescribed by the Depositary, notwithstanding any contrary indication herein. 

  
 136 

 Section 17.10 Other Rights; Liquidation Preference. The Series B Preferred Units shall not
have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth in this Article XVII or as required by applicable law. Notwithstanding
anything to the contrary in this Agreement, in the event of any liquidation, dissolution or winding up of the Partnership or the sale or disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the
Record Holders holding Preferred Units shall be entitled to be paid, or have the Partnership declare and set apart for payment, 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 Junior Securities, any accumulated and unpaid Series B Distributions and the positive value in each such Record Holder’s Capital Account
in respect of such Preferred Units. 
 ARTICLE XVIII

class United States mail or by other means of written communication to the Partner at the address described below. Except as otherwise provided herein, any notice, payment or report to be given or made to a Partner hereunder shall be deemed
conclusively to have been given or made, and the obligation to give such notice or report or to make such payment shall be deemed conclusively to have been fully satisfied, upon sending of such notice, payment or report to the Record Holder of such
Partnership Interests at his address as shown in the Register, regardless of any claim of any Person who may have an interest in such Partnership Interests by reason of any assignment or otherwise. Notwithstanding the foregoing, if (i) a Partner
shall consent to receiving notices, demands, requests, reports or proxy materials via electronic mail or by the Internet or (ii) the rules of the Commission shall permit any report or proxy materials to be delivered electronically or made available
via the Internet, any such notice, demand, request, report or proxy materials shall be deemed given or made when delivered or made available via such mode of delivery. An affidavit or certificate of making of any notice, payment or report in
accordance with the provisions of this Section 18.1 executed by the General Partner, the Transfer Agent or the mailing organization shall be prima facie evidence of the giving or making of such notice, payment or report. If any notice, payment or
report addressed to a Record Holder at the address of such Record Holder appearing in the Register is returned by the United States Postal Service marked to indicate that the United States Postal Service is unable to deliver it, such notice, payment
or report and any subsequent notices, payments and reports shall be deemed to have been duly given or made without further mailing (until such time as such Record Holder or another Person notifies the Transfer Agent or the Partnership of a change in
his address) if they are available for the Partner at the principal office of the Partnership for a period of one year from the date of the giving or making of such notice, payment or report to the other Partners.

  
 137 

 
Any notice to the Partnership shall be deemed given if received by the General Partner at the principal office of the Partnership designated pursuant to Section 2.3. The General Partner may rely
and shall be protected in relying on any notice or other document from a Partner or other Person if believed by it to be genuine. 
 (b) The
terms “in writing,” “written communications,” “written notice” and words of similar import shall be deemed satisfied under this Agreement by use of e-mail and other forms of electronic communication. 

Section 18.2 Further Action. The parties shall execute and deliver all documents, provide all information and take or refrain from
taking action as may be necessary or appropriate to achieve the purposes of this Agreement. 
 Section 18.3 Binding Effect. This
Agreement shall be binding upon and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns. 

Section 18.4 Integration. This Agreement constitutes the entire agreement among the parties hereto pertaining to the subject
matter hereof and supersedes all prior agreements and understandings pertaining thereto. 
 Section 18.5 Creditors. None of the
provisions of this Agreement shall be for the benefit of, or shall be enforceable by, any creditor of the Partnership. 
 Section 18.6
Waiver. No failure by any party to insist upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute waiver of any such
breach of any other covenant, duty, agreement or condition. 
 Section 18.7 Third-Party Beneficiaries. Each Partner agrees that
(a) any Indemnitee shall be entitled to assert rights and remedies hereunder as a third-party beneficiary hereto with respect to those provisions of this Agreement affording a right, benefit or privilege to such Indemnitee and (b) any Unrestricted
Person shall be entitled to assert rights and remedies hereunder as a third-party beneficiary hereto with respect to those provisions of this Agreement affording a right, benefit or privilege to such Unrestricted Person. 

  
 138 

 Section 18.8 Counterparts. This Agreement may be executed in counterparts, all of
which together shall constitute an agreement binding on all the parties hereto, notwithstanding that all such parties are not signatories to the original or the same counterpart. Each party shall become bound by this Agreement immediately upon
affixing its signature hereto or, in the case of a Person acquiring a Limited Partner Interest, pursuant to Section 10.1(b) without execution hereof. 

Section 18.9 Applicable Law; Forum, Venue and Jurisdiction; Waiver of Trial by Jury. 

(a) This Agreement shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to the principles
of conflicts of law. 
 (b) Each of the Partners and each Person or Group holding any beneficial interest in the Partnership (whether
through a broker, dealer, bank, trust company or clearing corporation or an agent of any of the foregoing or otherwise): 

(i) irrevocably agrees that any claims, suits, actions or proceedings (A) arising out of or relating in any way to this
Agreement (including any claims, suits or actions to interpret, apply or enforce the provisions of this Agreement or the duties, obligations or liabilities among Partners or of Partners to the Partnership, or the rights or powers of, or restrictions
on, the Partners or the Partnership), (B) brought in a derivative manner on behalf of the Partnership, (C) asserting a claim of breach of a duty (including a fiduciary duty) owed by any director, officer, or other employee of the Partnership or the
General Partner, or owed by the General Partner, to the Partnership or the Partners, (D) asserting a claim arising pursuant to any provision of the Delaware Act or (E) asserting a claim governed by the internal affairs doctrine shall be exclusively
brought in the Court of Chancery of the State of Delaware (or, if such court does not have subject matter jurisdiction, any other court located in the State of Delaware with subject matter jurisdiction), in each case regardless of whether such
claims, suits, actions or proceedings sound in contract, tort, fraud or otherwise, are based on common law, statutory, equitable, legal or other grounds, or are derivative or direct claims; 

(ii) irrevocably submits to the exclusive jurisdiction of such courts in connection with any such claim, suit, action or
proceeding; 
 (iii) agrees not to, and waives any right to, assert in any such claim, suit, action or proceeding that (A) it
is not personally subject to the jurisdiction of such courts or of any other court to which proceedings in such courts may be appealed, (B) such claim, suit, action or proceeding is brought in an inconvenient forum, or (C) the venue of such claim,
suit, action or proceeding is improper; 
 (iv) expressly waives any requirement for the posting of a bond by a party
bringing such claim, suit, action or proceeding; and 
 (v) consents to process being served in any such claim, suit, action
or proceeding by mailing, certified mail, return receipt requested, a copy thereof to such party at the address in effect for notices hereunder, and agrees that such services shall 

  
 139 

 
constitute good and sufficient service of process and notice thereof; provided, nothing in clause (v) hereof shall affect or limit any right to serve process in any other manner permitted
by law. 
 Section 18.10 Invalidity of Provisions. If any provision or part of a provision of this Agreement is or becomes for
any reason, invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions and/or parts thereof contained herein shall not be affected thereby and this Agreement shall, to the fullest extent
permitted by law, be reformed and construed as if such invalid, illegal or unenforceable provision, or part of a provision, had never been contained herein, and such provisions and/or part shall be reformed so that it would be valid, legal and
enforceable to the maximum extent possible. 
 Section 18.11 Consent of Partners. Each Partner hereby expressly consents and
agrees that, whenever in this Agreement it is specified that an action may be taken upon the affirmative vote or consent of less than all of the Partners, such action may be so taken upon the concurrence of less than all of the Partners and each
Partner shall be bound by the results of such action. 
 Section 18.12 Facsimile and Email Signatures. The use of facsimile
signatures and signatures delivered by email in portable document (.pdf) or similar format affixed in the name and on behalf of the transfer agent and registrar of the Partnership on Certificates representing Units, Series A Preferred Units or
