 ARTICLE II. 

REGISTRATION RIGHTS 

Section 2.01 Demand Registration. Upon request from any Holder Group at any time after the 180th day after the date hereof, the
Partnership shall prepare and file with the Commission a registration statement under the Securities Act providing for the resale of the Registrable Securities, which may, at the option of the Holder Group making such Demand Notice, be a
registration statement that provides for the resale of the Registrable Securities from time to time pursuant to Rule 415 under the Securities Act (the “Registration Statement”). Within two (2) business days of the
receipt of the Demand Notice, the Partnership shall give written notice of such Demand Notice to all Holders, and the Holders shall have three (3) business days following receipt of such notice of the Demand Notice from the Partnership to
request through such Holder’s Holder Group representative set forth in Section 3.01 in writing (including by electronic mail) to the Partnership to be included as a seller of Registrable Securities in such Registration Statement.
The Partnership shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective by the Commission as soon as reasonably practicable after the initial filing of the Registration Statement. The Registration
Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the Holders of any and all Registrable Securities covered by such Registration Statement (including those elected to be
included in such Registration Statement following notice of a Demand Notice from the Partnership pursuant to this Section 2.01). The Partnership shall use its commercially reasonable efforts to cause the Registration Statement filed
pursuant to this Section 2.01 to be continuously effective, supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until all Registrable Securities
covered by such Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). The Registration Statement when effective (and the documents incorporated therein by reference) shall comply as to
form in all material respects with all applicable requirements of the Securities Act and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements
therein not misleading. As soon as practicable following the date that the Registration Statement becomes effective, but in any event within two (2) business days of such date, the Partnership shall provide the Holders with written notice of
the effectiveness of the Registration Statement. Each Holder Group shall be limited to one (1) demand registration under this Section 2.01 in any twelve-month period (provided, however, that there shall be no limit on
the number of Shelf Registration Statements that may be required by the Holders hereunder), and the Partnership shall not be obligated to file more than one (1) Registration Statement within 120 days after the effective date of any Registration
Statement filed by the Partnership. Once a Holder’s Registrable Securities become eligible for resale without restriction and without the need for current public information pursuant to any section of Rule 144 (or any similar provision then in
effect) under the Securities Act, assuming the Holder of such Registrable Securities is not an affiliate (as defined in Rule 144(a)(1) under the Securities Act) of the Partnership, the applicable Holder Group may, at any time, request that the
Partnership take such steps as are reasonably necessary to deregister such Holder’s Registrable Securities. In connection with such request, such Holder’s rights under this Agreement shall all be terminated, including without limitation
the right to demand an Underwritten Offering and the right to participate in a Piggyback Registration, and such Holder shall no longer be subject to any obligations under this Agreement, including without limitation the obligation to enter into
letter agreements with underwriters pursuant to Section 2.12.

 Section 2.02 Underwritten and Redemptive Offerings. 

(a) Request for a Secondary Offering. If one or more Holders constituting a Holder Group collectively owns at least 2.0% of the
outstanding Registrable Securities of the Partnership and elect to dispose of Registrable Securities having a market price, based on the last sales price of the Common Units as of the trading date prior to the date of demand, of at least $25.0
million (subject to adjustment pursuant to Section 3.04) the Partnership shall, upon the written request by such Holder Group, retain underwriters in order to permit such Holders to effect such sale through an Underwritten Offering (a
“Secondary Offering”). Within two (2) business days of the receipt of the Demand Notice, the Partnership shall give written notice of such Demand Notice to all Holders, and the Holders shall have three (3) business
days following receipt of such notice of the Demand Notice from the Partnership to request through such Holder’s Holder Group representative set forth in Section 3.01 in writing (including by electronic mail) to the Partnership to
be included as a seller of Registrable Securities in such Underwritten Offering. The obligation of the Partnership to retain underwriters shall include the preparation and entry into an underwriting agreement, in customary form, with the Managing
Underwriter or underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.08 and taking all reasonable actions as requested by the Managing Underwriter or underwriters to
expedite or facilitate the disposition of such Registrable Securities, including causing its management to participate in a “roadshow” or similar marketing efforts. 

(b) Request for Equity-Financed Redemption. In lieu of a Secondary Offering pursuant to Section 2.02(a), the Partnership,
upon the written request (the “Redemption Demand Notice”) by a Holder Group (the “Redemptee” and collectively the “Redemptees”), shall use commercially reasonable efforts to
undertake an equity financing consisting of (i) a public offering (including an Underwritten Offering), (ii) a private placement or (iii) a combination of each (a “Primary Offering”), in each case, of an equal
number of Registrable Securities (the “Primary Units”). The net proceeds (after Registration Expenses but before Selling Expenses) of such Primary Offering will be used to redeem from each Redemptee the number of Registrable
Securities specified in each Redemptee’s Redemption Demand Notice (the “Redemption”). The obligation of the Partnership to undertake the Primary Offering shall include the preparation and filing of an offering document,
such as an offering memorandum or registration statement, as applicable, as well as the preparation and execution of a purchase agreement or underwriting agreement in customary form, which shall include, among other provisions, indemnities to the
effect and to the extent provided in Section 2.08 and taking all reasonable actions as are requested by the Managing Underwriter or underwriters or placement agent (as applicable, the “Selling Agent”), or, if no
Selling Agent, the Redemptees, to expedite or facilitate the disposition of Primary Units, including causing its management to participate in a “roadshow” or similar marketing efforts. 

(c) Limitation on Offerings. In no event shall the Partnership be required hereunder to participate in more than an aggregate of two
Primary Offerings or Secondary Offerings in any 12-month period. 

  
 5 

 (d) General Procedures. In connection with any Primary Offering or Secondary Offering
under this Agreement, the Partnership shall be entitled to select the Selling Agent, if any. In connection with any Primary Offering under this Agreement, the Partnership shall be obligated to enter into an underwriting agreement or purchase
agreement, as applicable, that contains such representations, covenants, indemnities and other rights and obligations as are customary. 

(e) Withdrawal. If any (i) Selling Holder disapproves of the terms of a Secondary Offering or (ii) Redemptee disapproves of
the terms of a Primary Offering, such Person may elect to withdraw its request that the Partnership undertake such offering by written notice to the Partnership; provided, however, that such withdrawal must be made at a time prior to
the time of pricing of such offering. No such withdrawal shall affect the Partnership’s obligation to pay Registration Expenses, if applicable. 

Section 2.03 Piggyback Rights. 

(a) Participation. So long as a Holder has Registrable Securities, if the Partnership proposes to file, whether for its own account or
for the account of the Holders: (1) a shelf registration statement (other than the Registration Statement contemplated by Section 2.01) or (2) a registration statement other than a shelf registration statement (other than a
registration statement on Form S-4 or S-8 or any successor forms thereto), including a registration statement for a Secondary Offering or a Primary Offering as contemplated by Section 2.02(a) or Section 2.02(b), respectively
(each of (1) and (2), a “Piggyback Registration”), then the Partnership shall give prompt written notice (a “Piggyback Notice”) (including notice by electronic mail) to each Holder holding at
least $0.5 million of the then-outstanding Registrable Securities of the Partnership (based on the last sales prices of the Common Units as of the trading date prior to the date of the Piggyback Notice) regarding such proposed registration, and such
notice shall offer such Holders the opportunity to include in such Piggyback Registration: (x) such number of Registrable Securities as each such Holder may request, or (y) a number of Primary Units in order to effect a Redemption of
Registrable Securities as such Holder may request. Each Piggyback Notice shall specify, at a minimum, the number and type of securities proposed to be registered, the proposed date of filing of such Piggyback Registration with the Commission, the
proposed means of distribution, the proposed Managing Underwriter or underwriters (if any and if known) and a good faith estimate by the Partnership of the proposed minimum offering price of such securities. Each such Holder shall make such request
through such Holder’s Holder Group representative set forth in Section 3.01 in writing to the Partnership (including by electronic mail) within five (5) business days (or one (1) business day in connection with any
overnight or bought Underwritten Offering) after the receipt of any such Piggyback Notice, which request shall specify the number of Registrable Securities intended to be disposed of by such Holder or the number of Registrable Securities such Holder
intends to have redeemed by the Partnership, and, subject to the terms and conditions of this Agreement, the Partnership shall use its reasonable best efforts to include in such Piggyback Registration all Registrable Securities held by such Holders
and/or a number Primary Units required to effect a Redemption of the Registrable Securities requested by such Holders; provided, that if, at any time after giving written notice of its intention to register equity securities and prior to the
effective date of the registration statement filed in connection with such registration, the Partnership shall determine for any reason not to register such equity securities, the Partnership may, at its election, give

  
 6 

 
written notice of such determination within five business days thereof to each Holder of Registrable Securities and, thereupon, shall not be obligated to register any Registrable Securities or
Primary Units in connection with such registration (but shall nevertheless pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of the Holders of Registrable Securities that a registration be effected
under Section 2.01 or Section 2.02. 
 (b) Priority. If in connection with an Underwritten Offering pursuant
to Section 2.02 or this Section 2.03, the Managing Underwriter shall advise the Partnership that, in its reasonable opinion, the number of securities requested and otherwise proposed to be included in such Underwritten
Offering exceeds the number which can be sold in such offering without an adverse effect on the price, timing or distribution of the securities to be offered (an “Adverse Effect”), then in the case of any such registration
pursuant to Section 2.02 or this Section 2.03, the Partnership shall include in such registration the number of Registrable Securities that such Managing Underwriter advises the Partnership can be sold without having such
Adverse Effect, with such number to be allocated (i) first to the Partnership, unless a Holder has initiated the Underwritten Offering under Section 2.02 or elected to join the Underwritten Offering under
Section 2.02(a), and (ii) second, and if any, the number of included Registrable Securities that, in the opinion of such Managing Underwriter, can be sold without having such Adverse Effect, with such number to be allocated pro rata
among the Holders (or to the Partnership if a Holder initiates the Underwritten Offering) that have requested to participate in such Underwritten Offering based on the relative number of Registrable Securities then held by each such Holder
(provided that any securities thereby allocated to a Holder that exceed such Holder’s request shall be reallocated among the remaining requesting Holders in like manner). 

Section 2.04 Delay Rights. If the General Partner determines that the Partnership’s compliance with its obligations under
this Article II would be materially detrimental to the Partnership and its partners because such registration would (a) materially interfere with a significant acquisition, reorganization, financing or other similar transaction involving
the Partnership, (b) require premature disclosure of material information that the Partnership has a bona fide business purpose for preserving as confidential or (c) render the Partnership unable to comply with applicable securities
laws, then the Partnership shall have the right to postpone compliance with its obligations to all but not less than all Holders under this Article II for a period of not more than three months; provided, that such right pursuant to
this Section 2.04 may not be utilized more than once in any twelve-month period. 
 Section 2.05 Sale Procedures. In
connection with its obligations under this Article II, the Partnership will, as expeditiously as possible: 
 (a) prepare and file
with the Commission such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be necessary
to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities or Primary Units covered by such Registration Statement, as applicable; 

(b) if a prospectus supplement, offering memorandum or similar marketing document will be used in connection with the marketing of a Primary
Offering or Secondary Offering and the Selling Agent notifies the Partnership in writing that, in the sole judgment of such Selling 

  
 7 

 
Agent, inclusion of detailed information in such prospectus supplement is of material importance to the success of such offering, the Partnership shall use its commercially reasonable efforts to
include such information in such prospectus supplement, offering memorandum or similar marketing document; 
 (c) furnish to each Selling
Holder (i) as far in advance as reasonably practicable before filing the Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably
complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission) or use of a similar marketing instrument,
and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with
respect to such information prior to filing the Registration Statement or such other registration statement or supplement or amendment thereto or use of a similar marketing instrument, and (ii) such number of copies of the Registration
Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto or similar marketing instrument as such Persons may reasonably request in order to facilitate the public sale or other
disposition of the Registrable Securities covered by the Registration Statement or other registration statement; 
 (d) if applicable, use
its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration Statement or the Primary Units covered by any other registration statement contemplated by this Agreement under the securities or blue
sky laws of such jurisdictions as the Selling Holders or, in the case of an Primary Offering or Secondary Offering, the Selling Agent, shall reasonably request; provided, however, that the Partnership will not be required to qualify generally
to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any jurisdiction where it is not then so subject; 

(e) promptly notify each Selling Holder and each Selling Agent, at any time when a prospectus is required to be delivered under the Securities
Act, of (i) the filing of the Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and,
with respect to the such Registration Statement or any other registration statement contemplated by this Agreement or any post-effective amendment thereto, when the same has become effective; and (ii) any written comments from the Commission
with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or
prospectus supplement thereto;

required to be delivered under the Securities Act, of: (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in such Registration Statement or any other registration statement contemplated by this
Agreement or any post-effective amendment thereto, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make

  
 8 

 
the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or threat of
issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the
receipt by the Partnership of any notification with respect to the suspension of the qualification of any Registrable Securities or Primary Units, as applicable, for sale under the applicable securities or blue sky laws of any jurisdiction.
Following the provision of such notice, the Partnership agrees to, as promptly as practicable, amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not
include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other
reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 
 (g) upon request and

as applicable, access to such information and Partnership personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act;

Partnership that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus.

information that, in the opinion of counsel to the Partnership, is reasonably required in order for a registration statement or prospectus supplement, as applicable, to comply with the Securities Act. 

Section 2.07 Expenses. 

(a) Expenses. The Partnership will pay all reasonable Registration Expenses of the Registration Statement, Underwritten Offering,

Exchange Act, and its directors, officers, employees or agents, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several,
to which such Selling Holder, director, officer, employee, agent or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in
respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Registration
Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of

employee, agent or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in the light of the circumstances under which such statement is made) contained in the Registration Statement or any other registration statement
contemplated by this Agreement, any preliminary prospectus or prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, any offering memorandum, or similar marketing document, or any amendment or
supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the
circumstances under which they were made) not misleading, and will reimburse each such Redemptee, its directors, officers, employee and agents, and each such controlling Person for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such Loss or actions or proceedings as such expenses are incurred; provided, however, that the Partnership will not be liable in any such case if and to the extent that any such Loss
arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Redemptee, its directors, officers, employees and agents or such controlling
Person in writing specifically for use in the Registration Statement or any other registration statement contemplated by this Agreement, prospectus, offering memorandum, or similar marketing document, or any amendment or supplement thereto, as
applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Redemptee or any such directors, officers, employees agents or controlling Person, and shall survive the sale of Primary
Units by the Partnership. 
 (b) By Each Holder. 

(i) Each Selling Holder agrees severally and not jointly to indemnify and hold harmless the Partnership, its directors,
officers, employees and agents and each Person, if any, who controls the Partnership within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity
from the Partnership to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such 

  
 12 

 
Selling Holder expressly for inclusion in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement, free
writing prospectus or final prospectus contained therein, or any amendment or supplement thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any
Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification. 

(ii) Each Redemptee agrees severally and not jointly to indemnify and hold harmless the Partnership, its directors, officers,
employees and agents and each Person, if any, who controls the Partnership within the meaning of the Securities Act or of the Exchange Act, and its directors, officers, employees and agents, to the same extent as the foregoing indemnity from the
Partnership to the Redemptee, but only with respect to information regarding such Redemptee furnished in writing by or on behalf of such Redemptee expressly for inclusion in any registration statement contemplated by this Agreement, any preliminary
prospectus, prospectus supplement, free writing prospectus or final prospectus contained therein, offering memorandum, or similar marketing document relating to the Primary Units, or any amendment or supplement thereto; provided,
however, that the liability of each Redemptee shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Redemptee from its pro rata share of the Redemption. 

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve it from any
liability that it may have to any indemnified party other than under this Section 2.08. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall
be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its
election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.08 for any legal expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably
acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses
available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party,
then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other
reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which
such indemnified party is entitled to indemnification hereunder without the consent of the 

  
 13 

 
indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party and
further, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of such indemnified party, unless the settlement
thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnified party. 

(d) Contribution. If the indemnification provided for in this Section 2.08 is held by a court or government agency of
competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the statements or
omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall the Selling Holder or Redemptee, as applicable, be required to contribute an aggregate amount in excess
of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder or Redemptee from the sale of Registrable Securities or Redemption following a Primary Offering giving rise to such indemnification. The relative fault of the
indemnifying party on the one hand and the indemnified party on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a
material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree
that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The
amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating
or defending any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of
fraudulent misrepresentation. 
 (e) Other Indemnification. The provisions of this Section 2.08 shall be in addition to
any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. 

Section 2.09 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission
that may permit the sale of the Registrable Securities to the public without registration, the Partnership agrees to use its commercially reasonable efforts to: 

(a) make and keep public information regarding the Partnership available, as those terms are understood and defined in Rule 144 under the
Securities Act, at all times from and after the date hereof; 

  
 14 

 (b) file with the Commission in a timely manner all reports and other documents required of the
Partnership under the Exchange Act at all times from and after the date hereof; and 
 (c) so long as a Holder owns any Registrable
Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Partnership, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing such Holder to sell any such securities without registration. 
 Section 2.10 Transfer or
Assignment of Registration Rights. The rights to cause the Partnership to register Registrable Securities or to undertake a Primary Offering granted to a Holder by the Partnership under this Article II and all other rights as a Holder
hereunder may be transferred or assigned by such Holder to one or more transferee(s) or assignee(s) of such Registrable Securities; provided, however, that (a) unless such transferee or assignee is an Affiliate of the Holder, each such
transferee or assignee holds Registrable Securities representing at least $2.0 million of Registrable Securities (based on the last sales price of the Common Units as of the trading date prior to the time of such transfer or assignment), subject to
adjustment pursuant to Section 3.04, (b) the Partnership is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the Registrable Securities
with respect to which such registration rights are being transferred or assigned, (c) each such transferee or assignee agrees to be bound by this Agreement; and (d) each such transferee or assignee shall be deemed to be included in the
applicable Holder Group of the transferring Holder for all purposes of this Agreement, unless such transferee or assignee is a member of another Holder Group at the time of such transfer or assignment, such that no transfer or assignment of any
Registrable Securities hereunder shall create an additional Holder Group; provided, further, that, notwithstanding anything to the contrary herein, effective upon receipt by Louisiana Midstream, LLC of Registrable Securities transferred by
PennTex Development or its transferees and subject to the appointment of a designated Holder Group representative to receive all notices and communications hereunder, Louisiana Midstream, LLC and its transferees, if any, shall constitute one, and
not more than one, additional Holder Group. 
 Section 2.11 Limitation on Subsequent Registration Rights. From and after the
date hereof, the Partnership shall not enter into any agreement with any current or future holder of any securities of the Partnership that would allow such current or future holder to require the Partnership to include securities in any
registration statement filed by the Partnership on a basis that would reduce or limit the rights of the Holders of Registrable Securities hereunder or otherwise on terms more favorable in the aggregate to such other holders than this Agreement. 

Section 2.12 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder who, along with its Affiliates, holds
at least five percent of the then-outstanding Registrable Securities agrees to enter into a customary letter agreement with underwriters providing such Holder will not effect any public sale or distribution of the Registrable Securities during a
period not to exceed 60 calendar days beginning on the date of a prospectus or prospectus supplement filed with the Commission with respect to the pricing of an Underwritten 

  
 15 

 
Offering, provided that (i) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the
Partnership or the officers, directors or any other unitholder of the Partnership on whom a restriction is imposed; and (ii) the restrictions set forth in this Section 2.12 shall not apply to any Registrable Securities that are
otherwise sold in connection with an Underwritten Offering pursuant to this Agreement.

Section 3.05 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if not

enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an
injunction or other equitable relief. The existence of this right will not preclude any such party from pursuing any other rights and remedies at law or in equity that such party may have. 

Section 3.06 Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

enforceability of such provision in any other jurisdiction. 
 Section 3.10 Scope of Agreement. This Agreement is intended by
the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions,
promises, warranties or undertakings, other than those set forth or referred to herein with respect to the rights granted by the Partnership set forth herein. This Agreement supersedes all prior agreements and understandings between the parties with
respect to such subject matter. 
 Section 3.11 Amendment. This Agreement may be amended only by means of a written amendment
signed by the Partnership and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of
such Holder, whether or not such Holder is disproportionately adversely affected compared to each other Holder. 
 Section 3.12 No
Presumption. If any claim is made by a party relating to any conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the

Holders or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment 

  
 18 

 
or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or
otherwise be incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the Holders or any former, current or future director, officer, employee,
agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of the Holders under this Agreement or any documents or instruments delivered in connection herewith or therewith or
for any claim based on, in respect of or by reason of such obligation or its creation, except in each case for any assignee of the Holders hereunder. 

Section 3.15 Independent Nature of Each Holder’s Obligations. The obligations of each Holder under this Agreement are several
and not joint with the obligations of any other Holder, and no Holder shall be responsible in any way for the performance of the obligations of any other Holder under this Agreement; provided, however, that each Holder consents to the
designation of the applicable Holder Group representative set forth in Section 3.01 to act on behalf of such Holder’s Holder Group pursuant to Section 2.01, Section 2.02 and Section 2.03. Nothing
contained herein, and no action taken by any Holder pursuant thereto, shall be deemed to constitute the Holders as a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in
any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Holder shall be entitled to independently protect and enforce its rights, including without limitation, the rights
arising out of this Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such purpose.

Provided Personnel are performing services for the General Partner hereunder), the Provided Personnel shall work solely under the direction, supervision and control of the General Partner. No Provided Personnel shall have authority or apparent
authority to act on behalf of Admin during any period such individual is under the direction, supervision or control of the General Partner. Individuals may be added or removed from the Provided Personnel Schedule from time to time by the execution
by Admin and the General Partner of a completed “Addition/Removal/Change of Responsibility of Provided Personnel” form, the form of which is attached to this Agreement as Exhibit C, which will be fully binding on Admin and the
General Partner for all purposes under this Agreement. Those rights and obligations of Admin and the General Partner under this Agreement that relate to individuals that were on the Provided Personnel Schedule but then later removed from the
Provided Personnel Schedule, which rights and obligations accrued before the removal of such individual, will survive the removal of such individual from the Provided Personnel Schedule to the extent necessary to enforce such rights and obligations.

 2.2 Period of Secondment. Admin will second, or cause its applicable Affiliate (such affiliate, a “Seconding
Affiliate”) to second, to the General Partner the Provided Personnel on the Effective Date and continuing, during the period (and only during the period) that the Provided Personnel are performing services for the General Partner, until
the earlier of: 
 (a) the end of the term of this Agreement; 

(b) such end date as is mutually agreed in writing by Admin and the General Partner; 

  
 2 

 (c) a withdrawal, departure, resignation or termination of such Provided
Personnel under Section 2.3; or 
 (d) a termination of Secondment of such Provided Personnel under
Section 2.4. 
 The period of time that any Provided Personnel is provided by Admin to the General Partner is referred to in
this Agreement as the “Period of Secondment.” At the end of the Period of Secondment for any Provided Personnel, such Provided Personnel will no longer be subject to the supervision, control or direction of the General
Partner. Admin and the General Partner acknowledge that certain of the Provided Personnel may also provide services to Admin and its Affiliates in connection with their respective operations unrelated to the General Partner (“Shared
Provided Personnel”), and Admin and the General Partner intend that such Shared Provided Personnel shall only be seconded to the General Partner during those times that the Shared Provided Personnel are performing services for the
General Partner hereunder. 
 2.3 Withdrawal, Departure or Resignation. If any Provided Personnel tenders his resignation to Admin as
an employee of Admin, Admin will promptly notify the General Partner. During the Period of Secondment of any Provided Personnel, Admin will not voluntarily withdraw or terminate any Provided Personnel except for terminations for cause (as reasonably
determined by Admin) or with the written consent of the General Partner (which may be through the execution of a completed “Addition/Removal/Change of Responsibility of Provided Personnel” form as set forth on Exhibit C), such
consent not to be unreasonably withheld, conditioned or delayed. Upon the termination of employment, the Provided Personnel will cease performing services for the General Partner. 

2.4 Termination of Secondment. The General Partner will have the right to terminate the Secondment to the General Partner of any
Provided Personnel for any reason at any time in accordance with the policies and procedures of Admin. Upon the termination of the Period of Secondment for any Provided Personnel other than the Shared Provided Personnel, the General Partner shall be
responsible for reimbursing Admin for any and all severance costs or other expenses (which, for the avoidance of doubt, shall constitute Provided Personnel Expenses hereunder) associated with the termination of such Provided Personnel’s
employment by Admin, provided that such termination of employment occurs within thirty (30) calendar days following the termination of the applicable Period of Secondment. Upon the termination of a Secondment, the Provided Personnel will cease
performing services for the General Partner. 
 2.5 Supervision. During the Period of Secondment, the General Partner shall: 

(a) be ultimately and fully responsible for the daily work assignments of the Provided Personnel (and with respect to Shared
Provided Personnel, during those times that the Shared Provided Personnel are performing services for the General Partner hereunder), including supervision of their the day-to-day work activities and performance consistent with the purposes stated
in Section 2.1 and the job functions set forth in the Provided Personnel Schedule; 
 (b) subject to Admin’s
policies and procedures, set the hours of work and the holidays and vacation schedules for Provided Personnel (other than with respect to Shared Provided Personnel, as to which the General Partner and Admin shall jointly determine); and 

(c) have the right to determine training which will be received by the Provided Personnel. 

  
 3 

 In the course and scope of performing any Provided Personnel job functions, the Provided
Personnel will be integrated into the organization of the General Partner, will report into the General Partner’s management structure and will be under the direct management and supervision of the General Partner. 

2.6 Provided Personnel Qualifications; Approval. Admin will provide such suitably qualified and experienced Provided Personnel as Admin
is able to make available to the General Partner, and the General Partner will have the right to approve such Provided Personnel. 
 2.7
Workers Compensation. At all times, Admin will maintain workers’ compensation or similar insurance (either through an insurance company or self-insured arrangement) applicable to the Provided Personnel, as required by applicable state
and federal workers’ compensation and similar laws, and will name the General Partner as an additional named insured under each such insurance policy. 

2.8 Benefit Plans. Neither the General Partner nor any Partnership Group Member shall be deemed to be a participating employer in any
Benefit Plan during the Period of Secondment. Subject to the General Partner’s reimbursement obligations hereunder, Admin (or its ERISA Affiliate) shall remain solely responsible for all obligations and liabilities arising under the express
terms of the Benefit Plans, and the Provided Personnel will be covered under the Benefit Plans subject to and in accordance with their respective terms and conditions, as they may be amended from time to time. Admin and its ERISA Affiliates may
amend or terminate any Benefit Plan in whole or in part at any time. During the Period of Secondment, neither the General Partner nor any Partnership Group Member shall assume any Benefit Plan or have any obligations, liabilities or rights arising
under the Benefit Plans, in each case except for cost reimbursement pursuant to this Agreement. 
 ARTICLE 3 

REIMBURSEMENT FOR PROVIDED PERSONNEL 

3.1 Reimbursement for Provided Personnel. On or before the fifteenth (15th) business day after the end of each month during the
Period of Secondment, Admin shall send an itemized invoice (in a form mutually agreed upon by the General Partner and Admin) to the General Partner detailing all reimbursable expenses under Section 3.2, as incurred by Admin with respect
to the Provided Personnel in connection with the performance of the Personnel Services during the preceding month (the “Services Reimbursement”). The General Partner shall, within fifteen (15) business days of receipt,
pay such invoice, except for any amounts therein being disputed in good faith by the General Partner. Any amounts that the General Partner has disputed in good faith and that are later determined by any arbitrator, court or other competent authority
having jurisdiction, or by agreement of Admin and the General Partner, to be owing from the General Partner to Admin shall be paid in full within fifteen (15) business days of such determination, together with interest thereon at the Interest
Rate from the date due under the original invoice until the date of payment. 
 3.2 Provided Personnel Expenses. Subject to
Section 3.3 and Section 3.4, the Services Reimbursement for each month during the Period of Secondment shall include all reasonable costs and expenses incurred for such month by Admin for the Provided Personnel (collectively,
the “Provided Personnel Expenses”), including, but not limited to, the following: 
 (a) salaries,
wages, bonuses or commissions (including payroll and withholding taxes associated therewith) of Provided Personnel; 
 (b)
the cost of providing the Benefit Plans to Provided Personnel; 

  
 4 

 (c) the cost of providing workers’ compensation coverage and/or benefits to
Provided Personnel; and 
 (d) reimbursable business expenses of Provided Personnel. 

Where it is not reasonably practicable to determine the amount of any Provided Personnel Expenses, Admin and the General Partner shall
mutually agree on the method of determining or estimating such amount, which may include the application of an agreed percentage benefit load to a Provided Personnel’s salary and wages in order to value certain of the benefits listed above. If
the actual amount of any cost or expense, once known, varies from the estimate used for billing purposes hereunder, the difference, once determined, shall be reflected as either a credit or additional charge in the next monthly invoice issued by
Admin, or in such manner as may otherwise be agreed between Admin and the General Partner. 
 3.3 Adjustments for Period of
Secondment. It is understood and agreed that the General Partner shall be liable for Provided Personnel Expenses to the extent, and only to the extent, they are attributable to the Period of Secondment. As such, if the Period of Secondment
begins on other than the first day of a month or ends on other than the last day of a month, the Provided Personnel Expenses for such month shall be prorated based on the number of days during such month that the Period of Secondment was in effect.

 3.4 Adjustments for Shared Services. With respect to each Provided Personnel who is a Shared Provided Personnel, Admin (or its
applicable Seconding Affiliate) will determine in good faith the percentage of such Shared Provided Personnel’s time spent providing services to the General Partner (the “Allocation Percentage”). For each month during
the Period of Secondment, the amount of the Services Reimbursement payable by the General Partner with respect to each Shared Provided Personnel shall be calculated by multiplying the Provided Personnel Expenses for such Shared Provided Personnel by
the Allocation Percentage for such Shared Provided Personnel. 
 ARTICLE 4 

ALLOCATION; RECORDS 
 4.1
Allocation; Records. Admin will use commercially reasonable efforts to maintain an allocation schedule reflecting the direct and indirect costs of the Provided Personnel Expenses based on the services that the Provided Personnel have provided
to the General Partner in relation to the Assets. The General Partner will use commercially reasonable efforts to keep and maintain books/records reflecting hours worked and costs and expenses incurred in connection with each of the Provided
Personnel. The General Partner and its representatives will have the right to audit such records and such other records as the General Partner may reasonably require in connection with its verification of the Provided Personnel Expenses during
regular business hours and on reasonable prior notice. 
 ARTICLE 5 

GENERAL AND ADMINISTRATIVE SERVICES 

5.1 General and Administrative Services Provided by Development. 

(a) Development agrees to provide, and agrees to cause its Affiliates to provide, to the General Partner, for the Partnership
Group’s benefit, certain centralized partnership and administrative services related to the Partnership’s ownership and operation of the Assets, including, without limitation, the general and administrative services listed on
Schedule 5.1(a) to this Agreement (collectively, the “G&A Services”). At the General Partner’s request from time to 

  
 5 

 
time, Development shall consult with the General Partner and provide such information as may be reasonably requested by the General Partner with respect to the performance of the G&A
Services. The Partnership shall have the right to terminate any or all of the G&A Services, without penalty, upon thirty (30) days’ prior written notice to Development. 

(b) As consideration for the provision of G&A Services, the Partnership will pay Development an administrative fee (the
“Administrative Fee”). For the period from the Effective Date through the end of the 2016 fiscal year, the Administrative Fee shall be payable on or before the fifteenth (15th) business day of each month and be
calculated as follows: 
 (i) for the period from and including the Effective Date to and including June 30, 2015 the Administrative Fee
shall be $2,778 per day; 
 (ii) for each calendar month after June 30, 2015 to and including the Mt. Olive Commencement Month, the
Administrative Fee shall be $83,333 per month; 
 (iii) for each calendar month after the Mt. Olive Commencement Month to and including the
month of December 2015, the Administrative Fee shall be $166,667 per month; 
 (iv) for each calendar month during the first six months of
the 2016 fiscal year, the Administrative Fee shall be $250,000; and 
 (v) for each calendar month during the last six months of the 2016
fiscal year, the Administrative Fee shall be $333,333. 
 (c) With respect to the 2017 fiscal year and each subsequent year
through the end of the term of this Agreement, Development and the General Partner shall negotiate in good faith and mutually agree on an annual Administrative Fee for the upcoming year, which shall be payable in equal monthly installments on or
before the fifteenth (15th) business day of each month. If Development and the General Partner are unable to agree on the amount of the Administrative Fee for an upcoming year on or prior to December 1 of the preceding year, then the
Administrative Fee for such upcoming year shall equal the Administrative Fee for the preceding year (or, with respect to the 2017 fiscal year, $4.0 million) as increased by a percentage equal to the change in the Producer Price Index over the
previous 12 calendar months; provided, however, that if Development and the General Partner are unable to agree on the amount of the Administrative Fee on or prior to March 31, then Development shall have the right to terminate
the G&A Services, without penalty. If the Agreement is not terminated and Development and the General Partner agree on the amount of the Administrative Fee, then Development shall thereafter charge such agreed-upon Administrative Fee for the
remainder of the year. 
 (d) The Partnership shall reimburse Development for all other direct or allocated costs and
expenses incurred by Development on behalf of the Partnership Group including, but not limited to: 
 (i) salaries, wages, bonuses or
commissions (including payroll and withholding taxes associated therewith) of employees of Development and its Affiliates (other than the Provided Personnel) who devote more than 50% of their business time to the business and affairs of the
Partnership Group, to the extent, but only to the extent, such employees perform services for the Partnership Group as determined in good faith by Development based on Development’s reasonable allocation methodologies as in effect from time to
time; 

  
 6 

 (ii) the cost of employee benefits relating to employees of Development and its Affiliates (other
than the Provided Personnel) who devote more than 50% of their business time to the business and affairs of the Partnership Group, including 401(k), pension, bonuses and health insurance benefits, to the extent, but only to the extent, such
employees perform services for the Partnership Group as determined in good faith by Development based on Development’s reasonable allocation methodologies as in effect from time to time; 

(iii) any expenses incurred or payments made by Development for insurance coverage with respect to the Assets or the business of the
Partnership Group; 
 (iv) all expenses and expenditures incurred by Development as a result of the Partnership becoming and continuing as a
publicly traded entity, including, but not limited to, costs associated with annual and quarterly reports, independent auditor fees, partnership governance and compliance, registrar and transfer agent fees, tax return and Schedule K-1
preparation and distribution, legal fees and independent director compensation; 
 (v) all sales, use, excise, value added or similar taxes,
if any, that may be applicable from time to time with respect to the G&A Services provided by Development to the Partnership Group pursuant to Section 5.1(a); and 

(vi) all costs for outside services, including any third-party legal, consulting, tax and accounting services not included in clause
(iv) above, that are incurred for the Partnership Group’s benefit. 
 On or before the fifteenth (15th) business day
after the end of each month during the term of this Agreement, Development shall send an itemized invoice (in a form mutually agreed upon by Development and the Partnership) to the Partnership detailing all reimbursable expenses under this
Section 5.1(d) incurred by Development during the preceding month. The Partnership shall, within fifteen (15) business days of receipt, pay such invoice, except for any amounts therein being disputed in good faith by the
Partnership. Any amounts that the Partnership has disputed in good faith and that are later determined by any court or other competent authority having jurisdiction, or by agreement of Development and the Partnership, to be owing from the
Partnership to Development shall be paid in full within fifteen (15) business days of such determination, together with interest thereon at the Interest Rate from the date due under the original invoice until the date of payment. For the
avoidance of doubt, the costs and expenses set forth in this Section 5.1(d) shall be paid by the Partnership in addition to, and not as a part of or included in, the Administrative Fee. 

Development does not make any representations or warranties of any kind, express or implied, with respect to the services (including the
G&A Services) to be provided under this Article 5, except that the services shall be provided in a reasonably timely manner by personnel that Development deems to be competent and qualified to perform such services.

 ARTICLE 6 

TERM; DEFAULT AND TERMINATION 

6.1 Term. The term of this Agreement will commence on the Effective Date and will continue for an initial period of ten
(10) years. Upon the expiration of the initial ten-year period, the term of this Agreement shall automatically extend for an additional five-year period, unless the General Partner or Development provides at least 30 days’ prior written
notice to the other Party prior to the expiration of such initial period that the Party wishes for this Agreement to expire at the end of the initial ten-year period. After the initial five-year renewal period, the term of this Agreement shall
automatically extend for additional five-year periods, unless the General Partner or Development provides prior written notice at least 30 days prior to the expiration of the applicable five-year period, that the Party wishes for this Agreement to
expire at the end of such five-year period. Upon proper notice by a Party to the other Party, in accordance with this Article 6, that the Party wishes for this Agreement to expire on the expiration of the applicable five- or ten-year
period, this Agreement shall not automatically extend, but shall instead expire upon the expiration of the five- or ten-year period and only those provisions that, by their terms, expressly survive this Agreement shall so survive. 

6.2 Default. A Party shall be in default under this Agreement if: (a) it fails to perform a material obligation and (b) such
failure continues for a period of thirty (30) days after notice thereof or, if such failure cannot reasonably be cured within such thirty (30) day period, such longer period (not to exceed sixty (60) days) so long as such Party is
diligently and continuously engaged in curing such failure. In the event a Party is in default of this Agreement, the non-defaulting Party may terminate this Agreement upon notice to the defaulting Party or submit any claims regarding the defaulting
Party’s non-performance to arbitration in accordance with Section 8.17, which, for the avoidance of doubt, permits the non-defaulting Party to seek interim relief and specific performance in connection with such arbitration
proceedings. 
 6.3 Termination. This Agreement may be terminated as follows, and only those provisions that, by their terms,
expressly survive this Agreement shall so survive: 
 (a) by the Partnership Group at any time upon thirty
(30) days’ prior written notice to Admin or Development; 
 (b) by any Party upon a default of this Agreement by
any other Party that has an obligation to such Party; or 
 (c) by any Party at any time upon a Partnership Change of
Control. 
 Any termination pursuant to this Section 6.3 shall be evidenced by a notice given by the Party effectuating such termination. 

ARTICLE 7 

INDEMNIFICATION 
 7.1
Indemnification by Development and Subsidiaries. Development and its Subsidiaries shall indemnify, protect and defend the Partnership Group and all of the officers, directors, employees and agents of any Partnership Group Member (each, an
“Indemnified Party” and, collectively, the “Indemnified Parties”) against, and hold the Indemnified Parties harmless from, any and against all losses (including lost profits), costs, damages, injuries,
taxes, penalties, interests, expenses, obligations, claims and liabilities (joint or severable) of any kind or nature whatsoever (collectively, the “Claims”) that are incurred by such Indemnified Parties in connection with,
relating to or arising out of (a) the breach by Development or any of its Subsidiaries, or their respective directors, officers, employees, agents, contractors, subcontractors or consultants of any term or condition of this Agreement, or
(b) the performance of any services under this Agreement; provided, however, that Development and its Subsidiaries shall not be obligated to indemnify, reimburse, defend or hold harmless any Indemnified 

  
 8 

 
Party for any Claims incurred by such Indemnified Party in connection with, relating to or arising out of (i) a breach by such Indemnified Party of this Agreement, (ii) the gross
negligence, willful misconduct, bad faith or reckless disregard of such Indemnified Party with respect to any services provided under this Agreement or (iii) the fraudulent or dishonest acts of such Indemnified Party. 

7.2 Indemnification Procedures. 

(a) An Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a Claim under this Article 7, it
will provide notice thereof to Admin or Development, as applicable, pursuant to Section 7.1 (the “Indemnifying Party”), specifying the nature of and specific basis for such claim, copies of all correspondence with third parties,
Governmental Authorities or other individuals relating to the claim, and other relevant information reasonably requested by the Indemnifying Party. 

(b) The Indemnifying Party shall have the right to control all aspects of the response to and/or defense of (and any
counterclaims with respect to) any Claims brought against the Indemnified Party that are covered by the indemnification under this Article 7, including correspondence and negotiation with Governmental Authorities, the selection of counsel and
engineering and other consultants, determination of the scope of and approach to any investigation or remediation, determination of whether to appeal any decision of any court, determination of whether to enter into any voluntary agreement with any
Governmental Authority, and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent of the Indemnified Party unless it includes a full release
of the Indemnified Party from such matter or issues, as the case may be. 
 (c) The Indemnified Party agrees to cooperate
fully with the Indemnifying Party, with respect to all aspects of the defense of any Claims covered by the indemnification under this Article 7, including the prompt furnishing to the Indemnifying Party of any correspondence or other notice
relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records or other information of the
Indemnified Party that the Indemnifying Party considers relevant to such defense and the making available to the Indemnifying Party of any employees of the Indemnified Party; provided, however, that in connection therewith the
Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the
Indemnified Party pursuant to this Section 7.2. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the
Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any Claims covered by the indemnification set forth in this Article 7; provided, however, that the Indemnified Party may, at its own option,
cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall
have the right to retain sole control over such defense. 
 (d) In determining the amount of any loss, cost, damage or
expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance
benefit shall be net of any incremental insurance premiums that become due and payable by the Indemnified Party as a result of such claim and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons.

preclude any other or further exercise thereof or the exercise of any other right or remedy granted hereby or any related document. The waiver by a Party of a breach of any provisions of this Agreement will not constitute a waiver of a similar
breach in the future or of any other breach or nullify the effectiveness of such provision.

constitutes and expresses the entire agreement between the Parties with respect to the subject matter hereof. All previous discussions, promises, representations and understandings relative thereto are hereby merged in and superseded by this

arbitration. In the case of three (3) arbitrators, one shall be appointed by the claimant(s) in the demand for arbitration, the second appointed by the respondent(s) within thirty (30) days of receipt of the demand for arbitration, and the
third, who shall act as chairman of the arbitral tribunal, appointed by the Parties within thirty (30) days of the appointment of the second arbitrator. If any arbitrators are not appointed within these time periods, the American Arbitration
Association shall make the appointment(s). All arbitrators must (a) be neutral parties who have never been officers, directors or employees of any Partnership Group Member, Development, Admin or their respective Affiliates and (b) have not
less than seven years’ experience in the energy industry. An arbitral tribunal constituted under this agreement may, unless consolidation would prejudice the rights of any Party, consolidate an arbitration hereunder with arbitration under the
Omnibus Agreement if the arbitration proceedings raise common questions of law or fact. If two or more arbitral tribunals under these agreements issue consolidation orders, the order issued first shall prevail. The award shall be made within twelve
months of the filing of the notice of intention to arbitrate (demand), and the arbitrators shall agree to comply with this schedule before accepting appointment. However, this time limit may be extended by the arbitrators for good cause shown, or by

required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of the other Parties.
