 8 












 THIRD, to the payment of Term Loan Excess Principal (the amounts so applied to be

FOURTH, after payment in full of all Pari Passu Lien Obligations, to the Grantors or their successors or assigns, or as a court of competent
jurisdiction may otherwise direct. 
 Notwithstanding the foregoing, distributions shall be subject to SECTION 1.01(b), including that with

Obligations on any Common Collateral shall be of equal priority. 
 (d)    For the avoidance of doubt, any amounts to be
distributed pursuant to this SECTION 2.01 shall be distributed to each Collateral Agent for further distribution to its Pari Passu Secured Parties.

official appointed for or over, attempt any action to take possession of, exercise any right, remedy or power with respect to, or otherwise take any action to enforce its Lien in or realize upon,
or take any other action available to it in respect of, any Common Collateral (including with respect to any intercreditor agreement with respect to any Common Collateral), whether under any Pari Passu Security Document, applicable law or otherwise,
it being agreed that only the Revolving Credit Facility Collateral Agent shall be entitled to take any such actions or exercise any such remedies with respect to Common Collateral (subject to the right of the Term Loan Collateral Agents and the
other Term Loan Secured Parties to take limited protective measures with respect to their Liens on the Common Collateral and to take certain actions that would be permitted to be taken by unsecured creditors, each as set forth in
Section 2.02(d) below). Notwithstanding the equal priority of the Liens securing each Series of Pari Passu Lien Obligations, the Revolving Credit Facility Collateral Agent may deal with the Common Collateral as if the Revolving Credit Facility
Collateral Agent had a senior Lien on such Common Collateral. No Term Loan Collateral Agent or any other Term Loan Secured Party will contest, protest or object to any foreclosure proceeding or action brought by the Revolving Credit Facility
Collateral Agent or any other exercise by the Revolving Credit Facility Collateral Agent of any rights and remedies relating to the Common Collateral. 

(b)    The Revolving Credit Facility Collateral Agent shall have the exclusive right on behalf of all Pari Passu Secured
Parties in any Insolvency or Liquidation Proceeding to credit bid for the Common Collateral using all or a pro rata portion of the Pari Passu Lien Obligations as consideration so long as the equity and/or assets distributed to the Pari Passu Secured
Parties as a result of any such successful credit bid are distributed on pro rata basis in accordance with Section 2.01(a). In any Insolvency or Liquidation Proceeding or other transaction involving the sale or other disposition of Common
Collateral, except as provided in the immediately preceding sentence, no Pari Passu Secured Party may credit bid for Common Collateral. 

(c)    Each of the Pari Passu Secured Parties and each of the Collateral Agents agrees that it will not (and hereby waives
any right to) contest or support any other Person in contesting, in any proceeding (including any Insolvency or Liquidation Proceeding), the perfection, priority, validity or enforceability under applicable law (including the Bankruptcy Code) of a
Lien held by or on behalf of any of the Pari Passu Secured Parties in all or any part of the Common Collateral, or the provisions of this Agreement; provided that nothing in this Agreement shall be construed to prevent or impair (i) the
rights of any Collateral Agent to enforce this Agreement or (ii) the rights of any Pari Passu Secured Party to contest or support any other Person in contesting the enforceability of any Lien purporting to secure (x) Pari Passu Lien
Obligations constituting unmatured interest pursuant to Section 502(b)(2) of the Bankruptcy Code or (y) obligations not constituting Pari Passu Lien Obligations. For the purposes of this Agreement, Liens subject to avoidance as a result of
a preference or fraudulent transfer under the Bankruptcy Code are not enforceable under applicable law, and any claim of preference or fraudulent transfer with respect to a Lien constitutes the contest of the enforceability of the Lien. 

(d)    Notwithstanding the foregoing rights of the Revolving Credit Facility Collateral Agent, each Collateral Agent and
each other Pari Passu Secured Party shall be entitled to: 

  
 10 












 (i)    exercise any rights and remedies against any of
the Grantors (other than rights and remedies against or with respect to any of the Common Collateral) pursuant to the Pari Passu Documents of the applicable Series, including acceleration; 

(ii)    file a claim or statement of interest with respect to its Series of Pari Passu Lien Obligations;
provided that a Grantor has become subject to an Insolvency or Liquidation Proceeding; 

(iii)    take any action not adverse to the Liens or the rights of any other Pari Passu Secured Party in
order to preserve or protect its Lien on the Collateral; 
 (iv)    file any necessary responsive or
defensive pleadings in opposition to any motion, claim, adversary proceeding or other pleading made by any Person objecting to or otherwise seeking the disallowance of the claims of such Pari Passu Secured Party, in accordance with the terms of this
Agreement; 
 (v)    file any pleadings, objections, motions or agreements or take any other action which
assert rights or interests available to unsecured creditors of the Parent or any Subsidiary thereof arising under either Bankruptcy Law or applicable non-bankruptcy law, in each case to the extent not
inconsistent with, or prohibited by, the terms of this Agreement; and 
 (vi)    vote on any plan of
reorganization and file any proof of claim in an Insolvency or Liquidation Proceeding in accordance with the terms of this Agreement. 

(e)    Each Collateral Agent agrees that it will provide the other Collateral Agents written notice of the occurrence of
any Event of Default (as defined in the applicable Pari Passu Document) which causes the acceleration of the applicable Series of Pari Passu Lien Obligations within two (2) Business Days of such occurrence (to the extent that it has received
notice of the occurrence of such Event of Default); provided that failure to provide such notice shall not (i) impair the rights or (ii) give rise to liability, in each case of the Collateral Agent that has failed to provide such notice.
Following an acceleration, the Revolving Credit Facility Collateral Agent agrees that it will upon reasonable prior request from time to time consult with the other Collateral Agents with respect to the Revolving Credit Facility Collateral
Agent’s anticipated disposition of any Common Collateral (but without any liability to comply with any actions discussed in such consultation) and provide the other Collateral Agents written notice of the Revolving Credit Facility Collateral
Agent’s intent to exercise any foreclosure with respect to the Common Collateral in accordance with Section 2.02(a) and Section 2.02(b) of this Agreement not less than two (2) Business Days prior to taking any such action in
accordance with Section 2.02(a) and Section 2.02(b) above. 
 SECTION 2.03.    No Interference; Payment
Over. (a) Each Term Loan Secured Party agrees that (i) it will not take or cause to be taken any action the purpose or intent of which is, or could be, to interfere, hinder or delay, in any manner, whether by judicial proceedings
or otherwise, any sale, transfer or other disposition of the Common Collateral by the Revolving Credit Facility Collateral Agent, (ii) it will not institute any suit or assert in any suit, bankruptcy, insolvency or other proceeding any claim
against the Revolving Credit Facility Collateral Agent 

  
 11 












 
or any other Revolving Credit Facility Secured Party seeking damages from or other relief by way of specific performance, instructions or otherwise with respect to any Common Collateral, and
neither the Revolving Credit Facility Collateral Agent nor any other Revolving Credit Facility Secured Party shall be liable for any action taken or omitted to be taken by the Revolving Credit Facility Collateral Agent or any other Revolving Credit
Facility Secured Party with respect to any Common Collateral in accordance with the provisions of this Agreement, (iii) it will not seek, and hereby waives any right, to have any Common Collateral or any part thereof marshaled upon any
foreclosure or other disposition of such Common Collateral and (iv) it will not attempt, directly or indirectly, whether by judicial proceedings or otherwise, to challenge the enforceability of any provision of this Agreement; provided
that nothing in this Agreement shall be construed to prevent or impair the rights of any of the Collateral Agents or any other Pari Passu Secured Party to enforce this Agreement. 

(b)    Each Pari Passu Secured Party hereby agrees that if it shall obtain possession of any Common Collateral or
Subordination Document Distribution or shall realize any proceeds or payment in respect of any such Common Collateral or Subordination Document Distribution (including pursuant to any Pari Passu Security Document or by the exercise of any rights
available to it under applicable law or in any Insolvency or Liquidation Proceeding or through any other exercise of remedies), at any time prior to the Discharge of Revolving Credit Facility Obligations, then it shall hold such Common Collateral,
proceeds or payment in trust for the other Pari Passu Secured Parties and promptly transfer such Common Collateral or Subordination Document Distribution, proceeds or payment, as the case may be, to the Revolving Credit Facility Collateral Agent, to
be distributed by the Revolving Credit Facility Collateral Agent in accordance with the provisions of SECTION 2.01(a) hereof. 

(c)    In furtherance of the foregoing, no Grantor shall, nor shall any Grantor permit any Subsidiary to, (x) grant
or permit or suffer to exist any Lien on any asset or property (other than any Intercreditor Excluded Collateral) to secure any Series of Pari Passu Lien Obligations unless it has granted a Lien on such asset or property to secure each other Series
of Pari Passu Lien Obligations (except that, notwithstanding this clause (x), no Grantor or Subsidiary shall be required to deliver a mortgage to secure the NewCo Term Loan Obligations or the SMLP Holdings Term Loan Obligations prior to the date set
forth in Section 5.12 of each Term Loan Credit Agreement) or (y) enter into any subordination agreement with the Pari Passu Secured Parties of any Series (or their respective Collateral Agents or Administrative Agents) in respect of
indebtedness owed or owing to such Grantor or Subsidiary unless it has entered into a subordination agreement with the Pari Passu Secured Parties of each other Series (or their respective Collateral Agents or Administrative Agents). 

(d)    Nothing in this SECTION 2.03 shall be construed to prevent or impair the rights of the Term Loan Collateral Agents
and the other Term Loan Secured Parties set forth in SECTION 2.02(d) hereof. 
 SECTION 2.04.    Automatic Release
of Liens; Amendments to Pari Passu Security Documents. (a) If, at any time any Common Collateral is transferred to a third party or otherwise disposed of, in each case, in connection with any enforcement action by the Revolving Credit
Facility Collateral Agent in accordance with the provisions of this Agreement, then (whether or not any Insolvency or Liquidation Proceeding is pending at the time) the Liens in favor of each 

  
 12 












 
Term Loan Collateral Agent for the benefit of the Term Loan Secured Parties represented by it upon such Common Collateral will automatically and simultaneously be released upon transfer or
disposition in connection with such enforcement action, as and when, but only to the extent, such Liens of the Revolving Facility Collateral Agent on such Common Collateral are released; provided that any proceeds of any Common Collateral realized
therefrom shall be applied pursuant to SECTION 2.01 hereof; and provided further, that the Revolving Credit Facility Collateral Agent shall provide prompt notice to each Term Loan Collateral Agent of the identity of the Common Collateral whose Lien
has been so automatically released. 
 (b)    If, at any time a Grantor is no longer a Loan Party (as defined in the
Revolving Credit Agreement) under the Revolving Credit Agreement, then the Liens in favor of each Term Loan Collateral Agent for the benefit of the Term Loan Secured Parties represented by it upon any Common Collateral of or in respect of any such
Grantor will automatically and simultaneously be released, as and when, but only to the extent, the corresponding Liens of the Revolving Facility Collateral Agent on such Common Collateral are released in connection with such Grantor ceasing to be a
Loan Party under the Revolving Credit Agreement; provided that the Revolving Credit Facility Collateral Agent shall provide prompt notice to each Term Loan Collateral Agent of the identity of such Grantor and the related Common Collateral whose Lien
has been so automatically released. 
 (c)    Each Pari Passu Secured Party agrees that, without the prior written
consent of any other Collateral Agent, any Collateral Agent may enter into any amendment to any Pari Passu Security Document solely as such Pari Passu Security Document relates to a particular Series of Pari Passu Lien Obligations (including,
without limitation, to release Liens securing such Series of Pari Passu Lien Obligations), all without affecting the priorities set forth in SECTION 2.01(a) or the provisions of this Agreement defining the relative rights of the Pari Passu Secured
Parties of any Series, so long as such amendment is in accordance with the Pari Passu Document pursuant to which such Series of Pari Passu Lien Obligations was incurred; provided that (i) such Collateral Agent accepts the effects herein of such
amendment, including the effects of any Collateral ceasing to be Common Collateral or creating Term Loan Excess Principal and (ii) nothing herein shall limit the effects of such amendment, including any breach caused thereby, under any other
Series of Pari Passu Documents. 
 (d)    Each Term Loan Collateral Agent agrees to execute and deliver (at the sole
cost and expense of the Grantors and upon the written direction of the NewCo Term Loan Administrative Agent or the SMLP Holdings Term Loan Administrative Agent, as applicable) all such authorizations and other instruments as shall reasonably be
requested by the Revolving Credit Facility Collateral Agent to evidence and confirm any release of Common Collateral, whether in connection with enforcement or the release of a Grantor pursuant to the preceding clauses or otherwise, or amendment to
any Pari Passu Security Document provided for in this Section. The NewCo Term Loan Administrative Agent and the SMLP Holdings Term Loan Administrative Agent hereby authorize their respective Term Loan Collateral Agent to take all actions required by
this Paragraph (d), and agree to provide timely (but in any event within five (5) Business Days) written direction to their respective Term Loan Collateral Agent to take any actions required by this Paragraph (d) upon written request from
their respective Term Loan Collateral Agent or the Revolving Credit Facility Collateral Agent. 

  
 13 












 (e)    In determining whether an amendment to any Pari Passu Security
Document is not prohibited by this SECTION 2.04, any Collateral Agent may conclusively rely on a certificate of an authorized officer of the Company stating that such amendment is not prohibited hereunder. 

SECTION 2.05.    Certain Agreements with Respect to Bankruptcy or Insolvency Proceedings. (a) This
Agreement shall continue in full force and effect notwithstanding the commencement of any proceeding under the Bankruptcy Code or any other federal, state or foreign bankruptcy, insolvency, receivership or similar law by or against any Grantor. 

(b)    If any Grantor shall become subject to a case (a “Bankruptcy Case”) under the Bankruptcy
Code (including, for the avoidance of doubt, a Bankruptcy Case filed by the Parent or any Subsidiary thereof that is not a Grantor) and the Parent and/or any Subsidiary thereof shall, as debtor(s)-in-possession, move for approval of financing (“DIP Financing”) to be provided by one or more lenders (the “DIP Lenders”) under Section 364 of
the Bankruptcy Code or the use of cash collateral under Section 363 of the Bankruptcy Code, unless the Revolving Credit Facility Collateral Agent shall then oppose or object to such DIP Financing or such DIP Financing Liens or use of cash
collateral, each Term Loan Secured Party agrees not to object to any such financing or to the Liens on any Collateral securing the same (“DIP Financing Liens”) or to any use of cash collateral that constitutes Collateral (and
(i) to the extent that such DIP Financing Liens are senior to the Liens on any Collateral for the benefit of the Revolving Credit Facility Secured Parties, each Term Loan Secured Party will subordinate its Liens with respect to such Collateral
on the same terms as the Liens of the Revolving Credit Facility Secured Parties are subordinated thereto (other than any Liens of any Pari Passu Secured Parties constituting DIP Financing Liens), and (ii) to the extent that such DIP Financing
Liens rank pari passu with the Liens on any Collateral granted to secure the Pari Passu Lien Obligations of the Revolving Credit Facility Secured Parties, each Term Loan Secured Party will confirm the priorities with respect to such Collateral as
set forth herein), in each case so long as (A) the Pari Passu Secured Parties of each Series retain the benefit of their Liens on all Common Collateral pledged to the DIP Lenders, including proceeds thereof arising after the commencement of
such proceeding, with the same priority vis-à -vis all the other Pari Passu Secured Parties (other than any Liens of the Pari Passu Secured Parties constituting
DIP Financing Liens) as existed prior to the commencement of the Bankruptcy Case, (B) the Pari Passu Secured Parties of each Series are granted Liens on any additional collateral pledged to any Pari Passu Secured Parties as adequate protection
with respect to Common Collateral, with the same priority vis-à -vis the Pari Passu Secured Parties as set forth in this Agreement, and (C) if any amount of
such DIP Financing or cash collateral is applied to repay any of the Pari Passu Lien Obligations with respect to any Common Collateral, such amount is applied pursuant to SECTION 2.01(a) of this Agreement, and (D) if any Pari Passu Secured
Party is granted adequate protection in respect of Common Collateral, including in the form of periodic payments, in connection with such DIP Financing or use of cash collateral, the proceeds of such adequate protection are applied pursuant to
SECTION 2.01(a) of this Agreement; provided that the Pari Passu Secured Parties of each Series shall have a right to object to the grant of a Lien to secure the DIP Financing over any Collateral subject to Liens in favor of the Pari Passu
Secured Parties of such Series (or its Collateral Agent) that is not Common Collateral; and provided, further, that the Pari Passu Secured Parties receiving adequate protection shall not object to any other Pari Passu Secured Party
receiving adequate protection comparable to any adequate protection granted to such Pari Passu Secured Parties in connection with a DIP Financing or use of cash collateral. 

  
 14 












 SECTION 2.06.    Reinstatement. In the event that any of
the Pari Passu Lien Obligations shall be paid in full and such payment or any part thereof shall subsequently, for whatever reason (including an order or judgment for disgorgement of a preference under the Bankruptcy Code, or any similar law, or the
settlement of any claim in respect thereof), be required to be returned or repaid, the terms and conditions of this ARTICLE II shall be fully applicable thereto until all such Pari Passu Lien Obligations shall again have been paid in full in cash.

 SECTION 2.07.    Insurance. As between the Pari Passu Secured Parties, to the extent permitted under
the Revolving Credit Agreement or the Revolving Credit Facility Collateral Agreement, the Revolving Credit Facility Collateral Agent shall have the right to adjust or settle any insurance policy or claim covering or constituting Common Collateral in
the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding affecting the Common Collateral. 

SECTION 2.08.    Refinancings. The Pari Passu Lien Obligations of any Series may be Refinanced, in whole or
in part, in each case, without notice to, or the consent (except to the extent a consent is otherwise required to permit the Refinancing transaction under any Pari Passu Document) of any Pari Passu Secured Party of any other Series, all without
affecting the priorities provided for herein or the other provisions hereof. 
 SECTION 2.09.    Possessory or
Control Collateral Agent. (a) The Revolving Credit Facility Collateral Agent agrees to hold any Common Collateral constituting Possessory Collateral or Control Collateral that is part of the Collateral in its possession or control (or
in the possession or control of its agents or bailees) as gratuitous bailee or sub-agent, as applicable, for the benefit of each other Pari Passu Secured Party and any assignee solely for the purpose of
perfecting the Lien granted in such Possessory Collateral or Control Collateral, if any, pursuant to the applicable Pari Passu Security Documents, in each case, subject to the terms and conditions of this SECTION 2.09. Pending delivery to the
Revolving Credit Facility Collateral Agent, each Term Loan Collateral Agent agrees to hold any Common Collateral constituting Possessory Collateral or Control Collateral, from time to time in its possession, as gratuitous bailee or sub-agent for the benefit of each other Pari Passu Secured Party and any assignee, solely for the purpose of perfecting the Lien granted in such Possessory Collateral or Control Collateral, if any, pursuant to the
applicable Pari Passu Security Documents, in each case, subject to the terms and conditions of this SECTION 2.09. If the holding of such Possessory Collateral or Control Collateral in accordance with this Section is insufficient to perfect the Lien
granted in such Possessory Collateral or Control Collateral for any Pari Passu Secured Party, and there is no other way for such other Pari Passu Secured Party to perfect on such Possessory Collateral or Control Collateral, then such failure of
perfection shall not constitute an Imperfection nor cause such Possessory Collateral or Control Collateral to fail to be Common Collateral for the purposes of this Agreement. 

(b)    The Revolving Credit Facility Collateral Agent shall, upon the Discharge of the Revolving Credit Facility
Obligations, transfer the possession and control of the Possessory Collateral, together with any necessary endorsements but without recourse or warranty, to the NewCo Term Loan Collateral Agent. In connection with any transfer under the foregoing
sentence by the Revolving Credit Facility Collateral Agent, the Revolving Credit Facility Collateral Agent agrees to take all actions in its power as shall be necessary or reasonably requested by the NewCo Term Loan Collateral Agent to permit such
Term Loan Collateral Agent to obtain, for the benefit 

  
 15 












 
of the Term Loan Secured Parties, a first priority Lien in the applicable Possessory Collateral. Each Grantor shall take, or cause to be taken, such further action as is reasonably required to
effectuate the transfer contemplated by this paragraph (b) and shall indemnify each Collateral Agent for loss or damage suffered by such Collateral Agent as a result of such transfer, except for loss or damage suffered by such Collateral Agent
as a result of its own willful misconduct or gross negligence (as determined in a final non-appealable judgment by a court of competent jurisdiction). 

(c)    Notwithstanding anything to the contrary herein, the duties or responsibilities of the Revolving Credit Facility
Collateral Agent and the Term Loan Collateral Agents under this SECTION 2.09 shall be limited solely to holding any Common Collateral constituting Possessory Collateral and Control Collateral as gratuitous bailee or
sub-agent, as applicable, for the benefit of each other Pari Passu Secured Party for purposes of perfecting the Lien held by such Pari Passu Secured Parties therein. 

(d)    The agreement of the Revolving Credit Facility Collateral Agent to act as gratuitous bailee and/or sub-agent pursuant to this SECTION 2.09 is intended, among other things, to satisfy the requirements of Sections 8-106(d)(3),
8-301(a)(2), 9-104(a)(2) and 9-313(c) of the UCC. 

SECTION 2.10.    Similar Liens and Agreements. 

(a)    Each Collateral Agent, on behalf of itself and the Pari Passu Secured Parties represented by it, hereby agrees that
each Collateral Agent shall have the right, but not the obligation, to take Liens on any or all of the Collateral. In furtherance of, but subject to the foregoing, the parties agree, subject to the other provisions of this Agreement: 

 

	 	(i)	 to provide advance written notice to each Collateral Agent of any grant of Liens on additional Collateral to
secure any Pari Passu Obligations for which such party is the Collateral Agent or the Grantor, including a description of Collateral to be granted, the identity of the Grantors providing the grant, the Pari Passu Secured Parties benefitting from the
grant and the documents and agreements to be used to create or evidence the grant; 


  

	 	(ii)	 upon request by any Collateral Agent, to cooperate in good faith (and to direct their counsel to cooperate in
good faith) from time to time in order to determine, the specific items included in the Collateral, the identity of the Grantors, the Pari Passu Secured Parties benefitting from the Collateral and the documents and agreements being used to create or
evidence the granting of such Collateral; and 


  

	 	(iii)	 that the documents and agreements creating or evidencing the Liens on the Common Collateral securing any Series
of the Pari Passu Obligations shall be in all material respects the same forms of documents securing each other Series of the Pari Passu Obligations (without requiring that all Collateral taken for any Series of the Pari Passu Obligations must be
taken by each Series of the Pari Passu Obligations). 



  
 16 












 (b)    Each Collateral Agent represents that such Collateral Agent has
the authority to represent and bind the Pari Passu Secured Parties contemplated to be represented by it hereunder and, on behalf of itself and the Pari Passu Secured Parties represented by it, agrees that such Collateral Agent or the applicable
Administrative Agent or other Pari Passu Secured Parties represented by it hereunder shall be solely responsible for the creation, maintenance and perfection of its Liens on the Collateral and the results thereof under this Agreement, including for
the purposes of Impairments and distributions under SECTION 2.01. 
 ARTICLE III 

EXISTENCE AND AMOUNTS OF LIENS AND OBLIGATIONS 

Whenever the Revolving Credit Facility Collateral Agent shall be required, in connection with the exercise of its rights or the performance of
its obligations hereunder, to determine the existence or amount of any Term Loan Obligations or the Common Collateral subject to any Lien securing the Term Loan Obligations, it may request that such information be furnished to it in writing by the
Term Loan Collateral Agents, and shall be entitled to make such determination on the basis of the information so furnished; provided, however, that if any Term Loan Collateral Agent shall fail or refuse reasonably promptly to provide
the requested information, the Revolving Credit Facility Collateral Agent shall be entitled to make any such determination or not make any determination by such method as it may, in the exercise of its good faith judgment, determine, including by
reliance upon a certificate of the Company. The Revolving Credit Facility Collateral Agent may rely conclusively, and shall be fully protected in so relying, on any determination made by it in accordance with the provisions of the preceding sentence
(or as otherwise directed by a court of competent jurisdiction) and shall have no liability to any Grantor, any other Pari Passu Secured Party or any other Person as a result of such determination. 

ARTICLE IV 
 THE
REVOLVING CREDIT FACILITY COLLATERAL AGENT 
 SECTION 4.01.    Authority. (a) Notwithstanding any
other provision of this Agreement, nothing herein shall be construed to impose any fiduciary or other duty on the Revolving Credit Facility Collateral Agent to any Term Loan Secured Party or give any Term Loan Secured Party the right to direct the
Revolving Credit Facility Collateral Agent, except that the Revolving Credit Facility Collateral Agent shall be obligated to distribute proceeds of any Common Collateral in accordance with SECTION 2.01 hereof and provide notice to the Term Loan
Agents in accordance with SECTION 2.02(e) hereof. 
 (b)    In furtherance of the foregoing, each Term Loan Collateral
Agent, on behalf of itself and the other Term Loan Secured Parties represented by it, acknowledges and agrees that the Revolving Credit Facility Collateral Agent shall be entitled, for the benefit of the Pari Passu Secured Parties, to sell, transfer
or otherwise dispose of or deal with any Common Collateral as 

  
 17 












 
provided herein and in the Revolving Credit Facility Security Documents, without regard to any rights to which the Term Loan Secured Parties would otherwise be entitled. Without limiting the
foregoing, each Term Loan Secured Party agrees that none of the Revolving Credit Facility Collateral Agent or any other Pari Passu Secured Party shall have any duty or obligation first to marshal or realize upon any type of Common Collateral (or any
other Collateral securing any of the Pari Passu Lien Obligations), or to sell, dispose of or otherwise liquidate all or any portion of such Common Collateral (or any other Collateral securing any Pari Passu Lien Obligations), in any manner that
would maximize the return to the Term Loan Secured Parties, notwithstanding that the order and timing of any such realization, sale, disposition or liquidation may affect the amount of proceeds actually received by the Term Loan Secured Parties from
such realization, sale, disposition or liquidation. Each of the Pari Passu Secured Parties waives any claim it may now or hereafter have against any Collateral Agent of any other Series of Pari Passu Lien Obligations or any other Pari Passu Secured
Party of any other Series arising out of (i) any actions which any Collateral Agent or any other Pari Passu Secured Party may take or omit to take (including, actions with respect to the creation, perfection or continuation of Liens on any
Collateral, actions with respect to the foreclosure upon, sale, release or depreciation of or failure to realize upon, any of the Collateral and actions with respect to the collection of any claim for all or any part of the Pari Passu Lien
Obligations from any account debtor, guarantor or any other party) in accordance with the Pari Passu Security Documents or any other agreement related thereto or to the collection of the Pari Passu Lien Obligations or the valuation, use, protection
or release of any security for the Pari Passu Lien Obligations, (ii) any election by the Revolving Credit Facility Collateral Agent or any holders of Pari Passu Lien Obligations, in any proceeding instituted under the Bankruptcy Code, of the
application of Section 1111(b) of the Bankruptcy Code or (iii) subject to SECTION 2.04, any borrowing by, or grant of a Lien or administrative expense priority under Section 364 of the Bankruptcy Code by, the Company or any of its
subsidiaries, as debtor-in-possession. Notwithstanding any other provision of this Agreement, no Collateral Agent (including the Revolving Credit Facility Collateral
Agent) shall accept any Common Collateral in full or partial satisfaction of any Pari Passu Lien Obligations pursuant to Section 9-620 of the Uniform Commercial Code of any jurisdiction, without the
consent of each of the Collateral Agents representing holders of Pari Passu Lien Obligations for each Series for which such Collateral constitutes Common Collateral. 

SECTION 4.02.    Rights as a Pari Passu Secured Party. The Person serving as the Revolving Credit Facility
Collateral Agent hereunder shall have the same rights and powers in its capacity as a Pari Passu Secured Party under any Series of Pari Passu Lien Obligations that it holds as any other Pari Passu Secured Party of such Series and may exercise the
same as though it were not the Revolving Credit Facility Collateral Agent, and the term “Pari Passu Secured Party” or “Pari Passu Secured Parties” or (as applicable), “Revolving Credit Facility Secured Party”,
“Revolving Credit Facility Secured Parties”, “Term Loan Secured Party” or “Term Loan Secured Parties”, shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as
the Revolving Credit Facility Collateral Agent hereunder in its individual capacity (to the extent applicable). Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity
for and generally engage in any kind of business with the Company or any Subsidiary or other Affiliate thereof as if such Person were not the Revolving Credit Facility Collateral Agent hereunder and without any duty to account therefor to any other
Pari Passu Secured Party. 

  
 18 












 SECTION 4.03.    Exculpatory Provisions. (a) The
Revolving Credit Facility Collateral Agent shall not have any duties or obligations except those expressly set forth herein and in the other Pari Passu Security Documents to which it is a party. Without limiting the generality of the foregoing, the
Revolving Credit Facility Collateral Agent: 
 (i)    shall not be subject to any fiduciary or other
implied duties of any kind or nature to any Person, regardless of whether an Event of Default has occurred and is continuing; 

(ii)    shall not have any duty to take any discretionary action or exercise any discretionary powers,
except discretionary rights and powers expressly contemplated hereby or by the Revolving Credit Facility Security Documents; provided that the Revolving Credit Facility Collateral Agent shall not be required to take any action that, in its
opinion or the opinion of its counsel, may expose the Revolving Credit Facility Collateral Agent to liability or that is contrary to any Pari Passu Security Document or applicable law; 

(iii)    shall not, except as expressly set forth herein and in the Revolving Credit Facility Security
Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Company or any of its Affiliates that is communicated to or obtained by the Person serving as the Revolving Credit Facility
Collateral Agent or any of its Affiliates in any capacity; 
 (iv)    shall not be liable for any action
taken or not taken by it (A) with the consent or at the request of the Term Loan Collateral Agents or (B) in the absence of its own gross negligence or willful misconduct (the presence of such gross negligence or willful misconduct as
determined in a final non-appealable judgment by a court of competent jurisdiction) or (C) in reliance on a certificate of an authorized officer of the Company stating that such action is not prohibited
by the terms of this Agreement. The Revolving Credit Facility Collateral Agent shall be deemed not to have knowledge of any Event of Default under the Term Loan Credit Agreements unless and until notice describing such Event of Default is given to
the Revolving Credit Facility Collateral Agent by any Term Loan Agent or the Company; 
 (v)    shall not
be responsible for or have any duty to ascertain or inquire into (A) any statement, warranty or representation made in or in connection with this Agreement or any other Pari Passu Security Document, (B) the contents of any certificate,
report or other document delivered hereunder or thereunder or in connection herewith or therewith, (C) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence
of any Default or Event of Default under any Series of Pari Passu Lien Obligations, (D) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Pari Passu Security Document or any other agreement, instrument or
document, or the creation, perfection or priority of any Lien purported to be created by the Pari Passu Security Documents, (E) the value or the sufficiency of any Collateral for any Series of Pari Passu Lien Obligations, or (F) the
satisfaction of any condition set forth in any Pari Passu Document, other than to confirm receipt of items expressly required to be delivered to the Revolving Credit Facility Collateral Agent pursuant to the terms herein; 

  
 19 












 (vi)    shall not have any fiduciary duties or
contractual obligations of any kind or nature under any other Pari Passu Document (other than under any Pari Passu Document to which it is a party and only to the extent it is acting in such capacity and as set forth in such Pari Passu Document),
but shall be entitled to all protections provided to the Revolving Credit Facility Collateral Agent therein; 

(vii)    with respect to the Term Loan Credit Agreements or any Pari Passu Security Document, may
conclusively assume that the Grantors have complied with all of their obligations thereunder unless advised in writing by any Term Loan Agent to the contrary specifically setting forth the alleged violation; and 

(viii)    may conclusively rely on any certificate of an authorized officer of the Company. 

(b)    Each Pari Passu Secured Party acknowledges that, in addition to acting as the initial Revolving Credit Facility
Collateral Agent, Wells Fargo Bank, National Association also serves as the Revolving Credit Facility Administrative Agent and each Pari Passu Secured Party hereby waives any right to make any objection or claim against Wells Fargo Bank, National
Association (or any successor Revolving Credit Facility Collateral Agent or any of their respective counsel) based on any alleged conflict of interest or breach of duties arising from Wells Fargo Bank, National Association (or any such successor)
serving as a Collateral Agent and also serving as the Revolving Credit Facility Administrative Agent. 
 SECTION
4.04.    Reliance by Revolving Credit Facility Collateral Agent. The Revolving Credit Facility Collateral Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice,
request, certificate, consent, statement, instrument, document or other writing (including, any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise
authenticated by the proper Person. The Revolving Credit Facility Collateral Agent also may rely upon any statement made to it orally or by telephone and believed in good faith by it to have been made by the proper Person, and shall not incur any
liability for relying thereon. The Revolving Credit Facility Collateral Agent may consult with legal counsel (who may include, but shall not be limited to counsel for the Company or counsel for the administrative agent under the Revolving Credit
Agreement), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. 

SECTION 4.05.    Delegation of Duties. The Revolving Credit Facility Collateral Agent may perform any and
all of its duties and exercise its rights and powers hereunder or under any other Pari Passu Security Document by or through any one or more sub-agents appointed by the Revolving Credit Facility Collateral
Agent. The Revolving Credit Facility Collateral Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Affiliates. The exculpatory
provisions of this Article shall apply to any such sub-agent and to the Affiliates of the Revolving Credit Facility Collateral Agent and any such sub-agent. 

  
 20 












 SECTION
4.06.    Non-Reliance on Revolving Credit Facility Collateral Agent and Other Pari Passu Secured Parties. Each Pari Passu Secured Party acknowledges that it has,
independently and without reliance upon the Revolving Credit Facility Collateral Agent, any Term Loan Collateral Agent or any other Pari Passu Secured Party or any of their Affiliates and based on such documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Agreement and the other Pari Passu Documents. Each Pari Passu Secured Party also acknowledges that it will, independently and without reliance upon the Revolving Credit
Facility Collateral Agent, any Term Loan Collateral Agent or any other Pari Passu Secured Party or any of their Affiliates and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions
in taking or not taking action under or based upon this Agreement, any other Pari Passu Document or any related agreement or any document furnished hereunder or thereunder.

 SECTION 5.02.    Waivers; Amendment; Grantor Joinder
Agreements. (a) No failure or delay on the part of any party hereto in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or
discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereto are cumulative and are not exclusive of any rights or
remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by any party therefrom shall in any event be effective unless the same shall not be prohibited by paragraph (b) of this Section,
and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on any party hereto in any case shall entitle such party to any other or further notice or demand in similar or
other circumstances. 
 (b)    Except as otherwise expressly provided herein, neither this Agreement nor any provision
hereof may be terminated, waived, amended or modified (other than pursuant to any Grantor Joinder Agreement) except pursuant to an agreement or agreements in writing entered into by each Collateral Agent and, solely to the extent the Company’s
or any other Grantor’s rights or obligations are affected or their obligations increased thereby, the Company. 

(c)    This Agreement shall terminate and be of no further force and effect upon the earlier to occur of (i) the
Discharge of the Common Collateral securing the Revolving Credit Facility Obligations and (ii) the Discharge of the Common Collateral securing the Term Loan Obligations, in each case subject to SECTION 2.06. 

(d)    The Company shall cause each Subsidiary of the Company which has granted a Lien pursuant to any Pari Passu Security
Document to secure any Series of Pari Passu Lien Obligations to promptly, but in any event no later than 30 days (or such longer period as the Collateral Agents in their sole discretion may specify) after such grant, execute and deliver to the
Collateral Agents a joinder to this Agreement substantially in the form of Exhibit A hereto (the “Grantor Joinder Agreement”). Such Subsidiary shall become a Grantor hereunder with the same force and effect as if
originally named as a Grantor herein. The rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor as a party to this Agreement. 

SECTION 5.03.    Parties in Interest. This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns, as well as the other Pari Passu Secured Parties, all of whom are intended to be bound by, and to be third party beneficiaries of, this Agreement and each of whom agrees to be bound hereby
by their acceptance of the agreements and instruments evidencing their applicable Pari Passu Lien Obligations. 
 SECTION
5.04.    Survival of Agreement. 
 (a)    All covenants, agreements, representations
and warranties made by any party in this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the removal or resignation of a Collateral Agent. 

(b)    If, in any Insolvency or Liquidation Proceeding, debt obligations of the reorganized debtor secured by Liens upon
any property of the reorganized debtor are distributed pursuant to a plan of reorganization or liquidation or similar dispositive restructuring plan on 

  
 23 












 
account of all Pari Passu Lien Obligations, then, to the extent the debt obligations distributed on account of all Pari Passu Lien Obligations are secured by Liens upon the same property, the
provisions of this Agreement will survive the distribution of such debt obligations pursuant to such plan and will apply with like effect to the Liens securing such debt obligations. 

SECTION 5.05.    Counterparts. This Agreement may be executed in counterparts, each of which shall
constitute an original but all of which when taken together shall constitute a single contract. Delivery of an executed signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of
this Agreement. This Agreement may be executed using Electronic Signatures (as defined below) (including, without limitation, facsimile and .pdf) and shall be considered an original, and shall have the same legal effect, validity and enforceability
as a paper record. For the avoidance of doubt, the authorization under this SECTION 5.05 may include, without limitation, use or acceptance by the parties hereto of a manually signed paper hereof which has been converted into electronic form (such
as scanned into PDF format), or an electronically signed communication converted into another format, for transmission, delivery and/or retention. For purposes hereof, “Electronic Signature” shall have the meaning assigned to
it by 15 USC §7006, as it may be amended from time to time. Upon the reasonable request of any party hereto, any Electronic Signature of any other party hereto shall, as promptly as practicable, be followed by such manually executed
counterpart. 
 SECTION 5.06.    Severability. Any provision of this Agreement held to be invalid, illegal
or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective solely to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions
hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 

SECTION 5.07.    Governing Law. THIS AGREEMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSES OF ACTION
(WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 

SECTION 5.08.    Submission to Jurisdiction; Waivers. Each Collateral Agent, on behalf of itself and the
Pari Passu Secured Parties of the Series for whom it is acting, irrevocably and unconditionally: 
 (a)    submits for
itself and its property in any legal action or proceeding relating to this Agreement and the Pari Passu Security Documents, or for recognition and enforcement of any judgment in respect thereof, to the exclusive general jurisdiction of the state and
federal courts located in New York County and appellate courts from any thereof and waives any objection to any action instituted hereunder in any such court based on forum non conveniens, and any objection to the venue of any action instituted
hereunder in any such court; 

  
 24 












 (b)    consents that any such action or proceeding may be brought in
such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court, and agrees not to plead or claim the same;

 (c)    agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by
registered or certified mail (or any substantially similar form of mail), postage prepaid, to such Person (or the applicable Collateral Agent) at the address referred to in SECTION 5.01; 

(d)    agrees that nothing herein shall affect the right of any other party hereto (or any Pari Passu Secured Party) to
effect service of process in any other manner permitted by law; and 
 (e)    waives, to the maximum extent not
prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this SECTION 5.08 any special, exemplary, punitive or consequential damages. 

SECTION 5.09.    WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY
OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER
INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.09. 
 SECTION
5.10.    Headings. Article, Section and Exhibit headings used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction or to be taken into consideration in
interpreting, this Agreement. 
 SECTION 5.11.    Conflicts. In the event of any conflict or inconsistency
between the provisions of this Agreement and the provisions of any of the other Pari Passu Documents or Pari Passu Security Documents, the provisions of this Agreement shall govern and control; provided, however, that in no event shall any amendment
of any provision of this Agreement affect the rights or obligations of the Grantors under the Pari Passu Documents or the Pari Passu Security Documents unless consented to in writing in advance by the Company. 

SECTION 5.12.    Provisions Solely to Define Relative Rights. The provisions of this Agreement are and are
intended solely for the purpose of defining the relative rights of the Pari Passu Secured Parties in relation to one another. None of the Grantors or any other creditor thereof shall have any rights or obligations hereunder, except as expressly
provided in this Agreement (provided that nothing in this Agreement (other than SECTION 2.04. SECTION 2.05, SECTION 2.06 or SECTION 2.09 or this ARTICLE V) is intended to or will amend, waive or otherwise


  
 25 












 
modify the provisions of the Revolving Credit Agreement, the Term Loan Credit Agreements, any other Pari Passu Documents or any Pari Passu Security Documents), and none of the Grantors may rely
on the terms hereof (other than Sections SECTION 2.04, SECTION 2.05, SECTION 2.08 and SECTION 2.09, ARTICLE III and this ARTICLE V). Nothing in this Agreement is intended to or shall impair the obligations of any Grantor, which are absolute and
unconditional, to pay the Pari Passu Lien Obligations as and when the same shall become due and payable in accordance with their terms. For the avoidance of doubt, nothing contained in this Agreement shall be construed to constitute a waiver or an
amendment of any covenant of the Parent or any Subsidiary thereof contained in any Pari Passu Document, which restricts the incurrence of any Indebtedness or the grant of any Lien. 

SECTION 5.13.    Integration. This Agreement, together with the other Pari Passu Documents, represents the
agreement of each of the Grantors and the Pari Passu Secured Parties with respect to the subject matter hereof and there are no promises, undertakings, representations or warranties by any Grantor, the Revolving Credit Facility Collateral Agent or
any Term Loan Collateral Agent relative to the subject matter hereof not expressly set forth or referred to herein or in the other Pari Passu Documents.

 [FORM OF GRANTOR JOINDER AGREEMENT] 

[FORM OF] GRANTOR JOINDER AGREEMENT NO. [    ] dated as of
[            ], 20[        ] (the “Joinder Agreement”) to the PARI PASSU INTERCREDITOR AGREEMENT dated as of
May 28, 2020 (the “Pari Passu Intercreditor Agreement”), among SUMMIT MIDSTREAM HOLDINGS, LLC, a Delaware limited liability (the “Company”), the other GRANTORS party thereto, WELLS FARGO BANK, NATIONAL
ASSOCIATION, as Revolving Credit Facility Collateral Agent, MIZUHO BANK (USA), as NewCo Term Loan Collateral Agent, MIZUHO BANK (USA), as SMLP Holdings Term Loan Collateral Agent and
[            ], a [_______], as an additional GRANTOR. 

A.    Capitalized terms used herein but not otherwise defined herein shall have the meanings assigned to such terms in the
Pari Passu Intercreditor Agreement. 

B.    [            ], a Subsidiary of the Company (the
“Additional Grantor”), has granted a Lien on all or a portion of its assets to secure Pari Passu Lien Obligations, and such Additional Grantor is not a party to the Pari Passu Intercreditor Agreement. 

C.    The Additional Grantor wishes to become a party to the Pari Passu Intercreditor Agreement and to acquire and
undertake the rights and obligations of a Grantor thereunder. The Additional Grantor is entering into this Joinder Agreement in accordance with the provisions of the Pari Passu Intercreditor Agreement in order to become a Grantor thereunder. 

Accordingly, the Additional Grantor agrees as follows, for the benefit of the Collateral Agents, the Company and each other party to the Pari
Passu Intercreditor Agreement: 
 SECTION 1.    Accession to the Intercreditor Agreement. In accordance with
Section 5.02(d) of the Pari Passu Intercreditor Agreement, the Additional Grantor (a) hereby accedes and becomes a party to the Pari Passu Intercreditor Agreement as a Grantor with the same force and effect as if
originally named therein as a Grantor, (b) agrees to all the terms and provisions of the Pari Passu Intercreditor Agreement and (c) shall have all the rights and obligations of a Grantor under the Pari Passu Intercreditor Agreement. 

SECTION 2.    Representations, Warranties and Acknowledgment of the Additional Grantor. The Additional Grantor
represents and warrants to each Collateral Agent and each Pari Passu Secured Party that this Joinder Agreement has been duly authorized, executed and delivered by such Additional Grantor and constitutes the legal, valid and binding obligation,
enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether
considered in a proceeding in equity or at law. 
 SECTION 3.    Counterparts. This Joinder Agreement may be
executed in multiple counterparts, each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Joinder Agreement shall become effective when each Collateral Agent shall have received a
counterpart of this Joinder Agreement that bears the signature of the Additional Grantor. Delivery of an executed signature page to this Joinder Agreement by facsimile or other electronic transmission shall be effective as delivery of a manually
signed counterpart of this Joinder Agreement. This Joinder Agreement may be executed using Electronic Signatures 











 
(including, without limitation, facsimile and .pdf) and shall be considered an original, and shall have the same legal effect, validity and enforceability as a paper record. For the avoidance of
doubt, the authorization under this Section 3 may include, without limitation, use or acceptance by the parties hereto of a manually signed paper hereof which has been converted into electronic form (such as scanned into PDF format), or an
electronically signed communication converted into another format, for transmission, delivery and/or retention. For purposes hereof, “Electronic Signature” shall have the meaning assigned to it by 15 USC §7006, as it may
be amended from time to time. Upon the reasonable request of any party to the Pari Passu Intercreditor Agreement, any Electronic Signature of any other party hereto shall, as promptly as practicable, be followed by such manually executed
counterpart. 
 SECTION 4.    Benefit of Agreement. The agreements set forth herein or undertaken pursuant
hereto are for the benefit of, and may be enforced by, any party to the Pari Passu Intercreditor Agreement. 
 SECTION
5.    Governing Law. THIS JOINDER AGREEMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSES OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS JOINDER AGREEMENT SHALL BE
CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 
 SECTION
6.    Severability. In case any one or more of the provisions contained in this Joinder Agreement should be held invalid, illegal or unenforceable in any respect, none of the parties hereto shall be required to comply with
such provision for so long as such provision is held to be invalid, illegal or unenforceable, but the validity, legality and enforceability of the remaining provisions contained herein and in the Pari Passu Intercreditor Agreement shall not in any
way be affected or impaired. The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the
invalid, illegal or unenforceable provisions. 
 SECTION 7.    Notices. All communications and notices hereunder
shall be in writing and given as provided in Section 5.01 of the Pari Passu Intercreditor Agreement. 











 IN WITNESS WHEREOF, the Additional Grantor has duly executed this Joinder Agreement to the
Pari Passu Intercreditor Agreement as of the day and year first above written.
