in accordance with GAAP as then in effect, provided that until such modification has been agreed, the covenants herein shall be interpreted, and all computations of amounts and ratios referred to herein shall be made, on the basis of GAAP as
in effect and applied immediately before such change shall have become effective. Notwithstanding any other provision contained herein, all terms of an accounting or financial nature used herein shall be construed, and all computations of amounts
and ratios referred to herein shall be made, (A) without giving effect to any election under Financial Accounting Standards Board Accounting Standards Codification 825 (or any other Accounting Standards Codification or Financial Accounting
Standard having a similar result or effect) (and related interpretations) to value any Indebtedness or other liabilities of the Borrower or any Subsidiary at “fair value”, as defined therein, (B) without giving effect to any treatment
of Indebtedness in respect of convertible debt instruments under Accounting Standards Codification 470-20 (or any 

  
 38 












 
other Accounting Standards Codification or Financial Accounting Standard having a similar result or effect) to value any such Indebtedness in a reduced or bifurcated manner as described therein,
and such Indebtedness shall at all times be valued at the full stated principal amount thereof, and (C) without giving effect to any change to GAAP occurring after May 26, 2017 as a result of the adoption of any proposals set forth in the
Proposed Accounting Standards Update, Leases (Topic 842), issued by the Financial Accounting Standards Board on February 25, 2016, or any other updates or proposals issued by the Financial Accounting Standards Board in connection
therewith, in each case if such change would require treating any lease (or similar arrangement conveying the right to use) as a capital lease where such lease (or such similar arrangement) was not required to be so treated under GAAP as in effect
on the Closing Date. 
 Section 1.03    Effectuation of Transfers. Each of the representations and warranties of
the Borrower contained in this Agreement (and all corresponding definitions) are made after giving effect to the Transactions, unless the context otherwise requires. 

Section 1.04    Divisions. For all purposes under the Loan Documents, in connection with any division under Delaware
law (or any comparable event under a different requirement of any Governmental Authority): (a) if any asset, right, obligation or liability of any Person becomes the asset, right, obligation or liability of a different Person, then it shall be
deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into existence, such new Person shall be deemed to have been organized on the first date of its existence by the holders of its
Equity Interests at such time. 
 ARTICLE II 

THE CREDITS 

Section 2.01    Closing Date Loans. As of the Closing Date and as contemplated by Section 6.2(e) of the Purchase
Agreement, NewCo agrees to make a loan to the Borrower in an aggregate principal amount equal to $28,208,630.60. 

Section 2.02    Promise to Repay Loan; Evidence of Debt. (a) The Borrower hereby unconditionally promises to
repay the outstanding principal amount of all Loans in full on the Maturity Date, together with all accrued but unpaid interest thereon, to the Administrative Agent for the account of each Lender. 

(b)    Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness
of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. 

(c)    The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made
hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder, and (iii) any amount received by the Administrative Agent hereunder for the account of the Lenders and each
Lender’s share thereof. 

  
 39 












 (d)    The entries made in the accounts maintained pursuant to
paragraph (b) or (c) of this Section shall be prima facie evidence absent manifest error of the existence and amounts of the obligations recorded therein; provided, that the failure of any Lender or the Administrative Agent to
maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans made in accordance with the terms of this Agreement. 

(e)    Any Lender may request that Loans made by it be evidenced by a promissory note substantially in the form of
Exhibit C. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to such Lender (or, if requested by such Lender, to such Lender and its registered assigns) in such form. Thereafter, the Loans
evidenced by such promissory note and interest thereon shall at all times (including, to the extent requested by any assignee, after assignment pursuant to Section 9.04) be represented by one or more promissory notes in such form payable to the
payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns). 

Section 2.03    Repayment of Loans. (a) All Loans shall be due and payable as set forth in Section 2.02(a).

 (b)    All mandatory prepayments pursuant to Section 2.04(b) or Section 2.04(c) or optional prepayments of
the Loans pursuant to Section 2.04(a), shall be applied ratably among the Lenders. For the avoidance of doubt, the phrase “ratably among the Lenders” shall mean ratably based upon the respective Percentage of each Lender at the time
of such prepayment. 
 (c)    Prior to any repayment or prepayment of the Loans, the Borrower shall notify the
Administrative Agent by telephone (confirmed by facsimile) not later than 2:00 p.m., New York City time, one Business Day before the scheduled date of such repayment or prepayment. Each repayment or prepayment shall be applied to the Loans such
that each Lender receives its ratable share of such repayment or prepayment (based upon the respective Percentages of the Lenders at the time of such repayment or prepayment). 

Section 2.04    Prepayment of Loans. (a) The Borrower shall have the right at any time and from time to time to
prepay Loans in whole or in part, without premium or penalty, in an aggregate principal amount that is an integral multiple of the Payment Multiple and not less than the Payment Minimum or, if less, the amount outstanding, subject to prior notice in
accordance with Section 2.03(c). 
 (b)    The Borrower shall apply (i) all Material Debt-Related Net Proceeds
received by the MLP Entity, SMPH, SMP, the Borrower or any Affiliate or Subsidiary of the Borrower and (ii) all Net Proceeds which, in the aggregate, are in excess of $125.0 million, received by the MLP Entity, SMPH, SMP, the Borrower or
any Affiliate or Subsidiary of the Borrower in connection with (x) the incurrence of Indebtedness pursuant to Section 6.01(j) and (y) any disposition made pursuant to Section 6.05(j), in each case, promptly upon (and in any event
within three Business Days of) receipt thereof to prepay any outstanding Loan in accordance with paragraphs (b) and (c) of Section 2.03; provided that the Borrower may use a ratable portion of such Material Debt-Related Net Proceeds
or Net Proceeds, as applicable, to prepay Indebtedness outstanding under the SMLP Holdings Credit Agreement (with such prepaid Indebtedness permanently extinguished), in an amount not to exceed the product of (y) the amount of such


  
 40 












 
Material Debt-Related Net Proceeds or Net Proceeds, as applicable, multiplied by (z) a fraction, the numerator of which is the outstanding principal amount of Indebtedness under the SMLP
Holdings Credit Agreement and the denominator of which is the sum of the outstanding principal amount of Indebtedness under the SMLP Holdings Credit Agreement and the outstanding principal amount of Loans hereunder. 

(c)    The Borrower shall notify the Administrative Agent in writing of any mandatory prepayment of Loans required to be
made by the Borrower pursuant to paragraph (b) of this Section 2.04 at least three Business Days prior to the date of such prepayment. Each such notice shall specify the date of such prepayment and provide a reasonably detailed calculation
of the amount of such prepayment. The Administrative Agent will promptly notify each Lender of the contents of the Borrower’s prepayment notice and of such Lender’s pro rata share of the prepayment. 

Section 2.05    Fees. All Fees shall be paid on the dates due, in immediately available funds, to the Collateral
Agent. Once paid, none of the Fees shall be refundable under any circumstances. 
 Section 2.06    Interest.
(a) The Borrower shall pay interest on the unpaid principal amount of each Loan at the rate of 8.00% per annum. 

(b)    Notwithstanding the foregoing, if any principal of or interest on any Loan or any Fees or other amount payable by
the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, the Borrower shall pay interest on such overdue amount, after as well as before judgment, at a rate equal to 12.00% per annum plus the
rate applicable to such Loans as provided in paragraph (a) of this Section; provided, that this paragraph (b) shall not apply to any Default or Event of Default that has been waived by the Lenders pursuant to Section 9.08. 

(c)    Accrued interest on each Loan shall be payable in kind by the Borrower in arrears on the last day of each calendar
quarter by adding the amount thereof to the outstanding principal amount of the Loans owed to the applicable Lenders, and such increased principal amount shall thereafter bear interest at the rate per annum set forth in paragraphs (a) and (b)
of this Section, as applicable, and be paid in accordance with Sections 2.02, 2.03 and 2.04; provided, that, at the option of the Administrative Agent, interest accrued pursuant to paragraph (b) of this Section shall be payable on
demand. 
 (d)    All computations of interest shall be made by the Administrative Agent taking into account the actual
number of days occurring in the period for which such interest is payable pursuant to this Section, and on the basis of a year of 360 days. 

Section 2.07    Taxes. (a) Any and all payments by or on account of any obligation of any Loan Party under any
Loan Document shall be made free and clear of and without deduction for any Taxes, except to the extent such withholding or deduction is required by applicable law. If a 

  
 41 












 
Loan Party, an Agent or any other Person acting on behalf of an Agent in regards to payments hereunder shall be required to deduct Indemnified Taxes or Other Taxes from such payments by
applicable law, then (i) the sum payable by the Loan Party shall be increased as necessary so that after making all required deductions for Indemnified Taxes and Other Taxes (including deductions applicable to additional sums payable under this
Section) the Agent or Lender, as applicable, receives an amount equal to the sum it would have received had no such deductions for Indemnified Taxes and Other Taxes been made, (ii) such Loan Party, Agent or other Person acting on behalf of the
Agent shall make such deductions and (iii) such Loan Party, Agent or other Person acting on behalf of the Agent shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. For purposes of
this Section 2.07, if a Lender is treated as a domestic partnership for U.S. federal income tax purposes any withholding or payment of a U.S. federal withholding tax by such Lender or by any direct or indirect member of such Lender that is a
domestic partnership or withholding foreign partnership for U.S. federal income tax purposes, with respect to any payments made by or on behalf of any Loan Party under this Agreement or any other Loan Document, shall be considered a withholding or
deduction of such U.S. federal withholding tax by Borrower. 
 If a payment made to a Lender under this Agreement would be subject to
U.S. federal withholding tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall
deliver to the Borrower and Administrative Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or Administrative Agent, such documentation prescribed by applicable law (including as prescribed
by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or Administrative Agent as may be necessary for the Borrower or Administrative Agent to comply with its obligations under FATCA, to
determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this paragraph, FATCA shall include any amendments to FATCA made
after the Closing Date. 
 (b)    In addition, each Loan Party shall pay any Other Taxes payable on account of any
obligation of such Loan Party and upon the execution, delivery or enforcement of, or otherwise with respect to, the Loan Documents, to the relevant Governmental Authority in accordance with applicable law. 

(c)    Each Loan Party shall indemnify each Agent and each Lender, within 30 days after written demand therefor, for
the full amount of any Indemnified Taxes or Other Taxes (other than Indemnified Taxes or Other Taxes resulting from gross negligence or willful misconduct of the applicable Agent or such Lender as determined in the final, nonappealable judgment of a
court of competent jurisdiction) without duplication of any amounts indemnified under Section 2.07(a)) imposed or assessed on (and whether or not paid directly by) the Agent or such Lender, as applicable, with respect to any payment by or on
account of any obligation of such Loan Party under, or otherwise with respect to, any Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any reasonable expenses
arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed 

  
 42 












 
or asserted by the relevant Governmental Authority; provided, that a certificate as to the amount of such payment, liability, imposition or assessment and setting forth in reasonable
detail the basis and calculation for such payment or liability delivered to such Loan Party by a Lender, or by an Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error of the Lender or the Agent, as applicable.

 (d)    As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Loan Party to a Governmental
Authority such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such
payment reasonably satisfactory to the Administrative Agent. 
 (e)    Each Lender that is not a “United States
Person” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall, to the extent it may lawfully do so, deliver to the Borrower and the Administrative Agent two
copies of U.S. Internal Revenue Service Form W-8BEN (claiming the benefits of an applicable income tax treaty), W-8EXP,
W-8IMY (together with any required attachments) or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from
U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest,” a statement substantially in the form of Exhibit D and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender (with any other required forms
attached) claiming complete exemption from or a reduced rate of U.S. federal withholding tax on all payments by or on behalf of the Borrower under this Agreement and the other Loan Documents. Each Lender that is not a Non-U.S. Lender shall, to the extent it may lawfully do so, deliver to the Borrower and the Administrative Agent two copies of U.S. Internal Revenue Service
Form W-9, properly completed and duly executed by such Lender, claiming complete exemption (or otherwise establishing an exemption) from U.S. backup withholding on all payments under this Agreement
and the other Loan Documents. Such forms shall be delivered by each Lender, to the extent it may lawfully do so, on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant
purchases the related participation). In addition, each Lender, to the extent it may lawfully do so, shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Lender. Each Lender shall promptly
notify the Borrower and the Administrative Agent at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower or the Administrative Agent (or any other form of certification adopted by
the U.S. taxing authorities for such purpose). Without limiting the foregoing, any Lender that is entitled to an exemption from or reduction of withholding Tax otherwise indemnified against by a Loan Party pursuant to this Section 2.07
with respect to payments under any Loan Document shall deliver to the Borrower or the relevant Governmental Authority (with a copy to the Administrative Agent), to the extent such Lender is legally entitled to do so, at the time or times prescribed
by applicable law such properly completed and executed documentation prescribed by applicable law as may reasonably be requested by the Borrower or the Administrative Agent to permit such payments to be made without such withholding tax or at a
reduced rate; provided, that in such Lender’s judgment such completion, execution or submission would not materially prejudice such Lender. 

(f)    The Administrative Agent shall deliver to the Borrower, on or before the Closing Date, two duly completed copies of
Internal Revenue Service Form W-9. 

  
 43 












 (g)    If an Agent or any Lender determines, in good faith and in its
sole discretion, that it has received a refund of Indemnified Taxes or Other Taxes as to which it has been indemnified by a Loan Party or with respect to which a Loan Party has paid additional amounts pursuant to this Section 2.07, it shall pay
over such refund to such Loan Party (but only to the extent of indemnity payments made, or additional amounts paid, by such Loan Party under this Section 2.07 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net
of all out-of-pocket expenses of the Agent or Lender (including any Taxes imposed with respect to such refund) as is determined by the Agent or Lender in good faith
and in its sole discretion, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that such Loan Party, upon the request of the Agent or Lender agrees to repay as
soon as reasonably practicable the amount paid over to such Loan Party (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Agent or Lender in the event such Agent or Lender is required to repay such
refund to such Governmental Authority. This paragraph shall not be construed to require the Agent or Lender to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the Loan Parties or any
other Person. 
 Section 2.08    Payments Generally; Pro Rata Treatment; Sharing of
Set-offs. (a) Unless otherwise specified, the Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or of amounts payable under Section 2.07 or
otherwise) prior to 2:00 p.m., New York City time, on the date when due, in immediately available funds, without condition or deduction for any defense, recoupment, set-off or counterclaim. Any amounts
received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the
Administrative Agent to the applicable account designated to the Borrower by the Administrative Agent, except that payments pursuant to Sections 2.07 and 9.05 shall be made directly to the Persons entitled thereto. The Administrative Agent
shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment
shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder of principal or interest in respect of any Loan
shall be made in U.S. Dollars. All payments of other amounts due hereunder or under any other Loan Document shall be made in U.S. Dollars. Any payment required to be made by the Administrative Agent hereunder shall be deemed to have been
made by the time required if the 

  
 44 












 
Administrative Agent shall, at or before such time, have taken the necessary steps to make such payment in accordance with the regulations or operating procedures of the clearing or settlement
system used by the Administrative Agent to make such payment. 
 (b)    If at any time insufficient funds are received
by and available to the Administrative Agent from the Borrower to pay fully all amounts of principal, interest, fees and other amounts then due from the Borrower hereunder, such funds shall be applied first, to any Agent’s fees and
reimbursable expenses then due and payable pursuant to any of the Loan Documents; second, to all reimbursable expenses of the Lenders then due and payable pursuant to any of the Loan Documents, ratably among the Lenders in proportion to the
respective amounts of such fees and expenses payable to them; third, to interest and fees then due and payable hereunder, ratably among the Lenders in proportion to the respective amounts of such interest and fees payable to them; and
fourth, to the principal balance of the Loans, until the same shall have been paid in full, ratably among the Lenders in proportion to such Lender’s Percentage. 

(c)    If any Lender shall, by exercising any right of set-off or counterclaim,
through the application of any proceeds of Collateral or otherwise, obtain payment in respect of any principal of or interest on any of its Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans
and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided, that (i) if any such participations are purchased and
all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph (c)
shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any
of its Loans to any assignee or participant, other than to the Borrower or any Restricted Subsidiary (as to which the provisions of this paragraph (c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 

(d)    Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment
by the Borrower is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith
and may, in reliance upon such assumption, distribute to the Lenders, as applicable, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders, as applicable, severally agrees to repay to the
Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at
the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. 

  
 45 












 (e)    If any Lender shall fail to make any payment required to be made
by it pursuant to Section 2.08(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy
such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 
 (f)    None
of the funds or assets of the Borrower that are used to pay any amount due pursuant to this Agreement and the other Loan Documents shall constitute, to the Borrower’s knowledge, funds obtained from transactions with or relating to
Anti-Corruption Laws or Sanctions.

each Subsidiary Loan Party under and as defined in any documentation documenting any junior indebtedness of the Borrower and each Subsidiary Loan Party. Each Collateral Document delivered pursuant to Section 4.01, 5.10 and 5.12 will, upon
execution and delivery thereof, be effective to create in favor of the Collateral Agent, for the benefit of the Secured Parties, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof. In the case
of the Pledged Collateral described in the Collateral Agreement, when stock certificates representing such Pledged Collateral are delivered to the Collateral Agent (or the Revolver Collateral Agent as gratuitous bailee under the Intercreditor
Agreement), and in the case of the other Collateral described in the Collateral Agreement, when financing statements and other filings specified therein in appropriate form are filed in the offices specified therein, the Lien created by the

obtained by filing financing statements, making such other filings specified therein or by possession, as security for the Obligations. In each case of the security interests in favor of the Collateral Agent, for the benefit of the Secured Parties,
described in the preceding sentences, such security interests are prior and superior in right to any other Person, subject, in the case of Pledged Collateral, to Liens permitted by Section 6.02(d), (e), (n), (u), (bb), (ff) and (hh); in the
case of Mortgaged Property, to Permitted Real Property Liens; and in the case of any other Collateral (except Pledged Collateral and Mortgaged Property), to Liens permitted by Section 6.02. 

Section 3.15    Foreign Corrupt Practices, Sanctions. None of the Borrower nor any of its Subsidiaries, nor any
director, officer, agent or employee of any such the Borrower or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a material violation by such Persons of the FCPA or any other Anti-Corruption
Laws, including without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other Property, gift,
promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in
contravention of the FCPA, and the Borrower and its Subsidiaries have conducted their business in material compliance with the FCPA. None of (i) the Borrower, its Subsidiaries or any of their respective Subsidiaries or, to the


  
 51 












 
knowledge of Borrower or its Subsidiaries, any of their respective directors, officers or employees, or (ii) to the knowledge of the Borrower or its Subsidiaries, any agent or Affiliate of
the Borrower or any of its Subsidiaries which agent or Affiliate will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person.

Borrower’s reasonable business judgment obtain, preserve, renew, extend and keep in full force and effect the permits, franchises, authorizations, patents, trademarks, service marks, trade names, copyrights, licenses and rights with respect

each case except as expressly permitted by this Agreement); in each case in this paragraph (b) except where the failure to do so could not reasonably be expected to have a Material Adverse Effect. 

Section 5.02    Insurance. (a) Keep its insurable properties insured at all times by financially sound and
reputable insurers in such amounts as shall be customary for similar businesses and maintain such other reasonable insurance, of such types (including, for the avoidance of doubt, property and casualty insurance policies), to such extent and against
such risks, as is customary with companies in the same or similar businesses and maintain such other insurance as may be required by law or any other Loan Document. 

(b)    To the extent any “Building” or “Manufactured (Mobile) Home” (each, as defined in the
applicable Flood Insurance Laws and only to the extent not constituting Excluded Assets) that comprises a Gathering Station (or part thereof) constituting Mortgaged Property is subject to the provisions of the Flood Insurance Laws,
(i) (A) concurrently with the delivery of any Mortgage in favor of the Collateral Agent in connection therewith, and (B) at any other time after the delivery of such Mortgage, if necessary for compliance with applicable Flood

solely to their insurance companies or any parties other than the aforesaid parties for the recovery of such loss or damage and (B) such insurance companies shall have no rights of subrogation against the Agents, the Lenders or their agents or
employees. If, however, the insurance policies do not provide waiver of subrogation rights against such parties, as required above, then the Borrower hereby agrees, to the extent permitted by law, to waive, and to cause each of its Restricted
Subsidiaries to waive, its right of recovery, if any, against the Agents, the Lenders and their agents and employees; and 

(ii)    the designation of any form, type or amount of insurance coverage by the Administrative Agent, the
Collateral Agent or the Lenders under this Section 5.02 shall in no event be deemed a representation, warranty or advice by the Administrative Agent, the Collateral Agent or the Lenders that such insurance is adequate for the purposes of the
business of the Borrower or any Restricted Subsidiary or the protection of their properties. 

Section 5.03    Taxes and Contractual Obligations. (a) Pay and discharge promptly when due all material Taxes,
assessments and governmental charges or levies imposed upon it or upon its income or profits or in respect of its property, before the same shall become delinquent or in default, as well as all lawful claims for labor, materials and supplies or
otherwise that, if unpaid, might give rise to a Lien upon such properties or any part thereof; provided, that such payment and discharge shall not be required with respect to any such Tax, assessment, charge, levy or claim to the extent that
(i) the validity or amount thereof shall be contested in good faith by appropriate proceedings, and the Borrower or the affected Restricted Subsidiary, as applicable, shall have set aside on its books adequate reserves in accordance with GAAP
with respect thereto or (ii) the failure to pay or discharge would not reasonably be expected to have a Material Adverse Effect. 

(b)    With respect to payment obligations in any contract or agreement, pay, discharge or otherwise satisfy at or before
maturity or before they become delinquent, as the case may be, all its material obligations of whatever nature that by law have become or might become a Lien (other than with respect to Liens permitted pursuant to Section 6.02) imposed upon it
or upon its Properties, except where the amount or validity thereof is currently being contested in good faith by appropriate proceedings and adequate reserves in conformity with GAAP with respect thereto have been provided on the books of the
Borrower or the affected Restricted Subsidiary or if the failure to pay, discharge or otherwise satisfy such obligation would not reasonably be expected to have a Material Adverse Effect. 

(c)     (i) Perform and observe in all material respects all of the covenants and agreements (other than covenants or
agreements to pay covered in Section 5.03(b)) contained in each Material Contract to which the Borrower or a Subsidiary Loan Party is a party that are

provided to be performed and observed on the part of the Borrower or such Subsidiary Loan Party (taking into account any grace period); and (ii) diligently and in good faith enforce, using
appropriate procedures and proceedings, all of such Person’s material rights and remedies under (including taking all diligent actions required to collect amounts owed to such Person by any other parties thereunder) each Material Contract,

terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. 

(b)    [Reserved.]

its capacity as a Lender as any other Lender, and may exercise the same as though it were not an Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires,
include a Person serving as an Agent hereunder in its individual capacity. 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 Borrower or any Subsidiary or other Affiliate thereof as if such Person were not an Agent hereunder and without any duty to account therefor to the Lenders.

forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, no Agent:

provided for herein or in the other Loan Documents); provided, that no Agent shall be required to take any action that, in its opinion or the opinion of its counsel, may expose such Agent
to liability or that is contrary to any Loan Document or applicable law;

such Agent or any of its Affiliates in any capacity; 
 (d)    shall be liable for any action taken or not taken by it
(i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as such Agent shall believe in good faith shall be necessary, under the circumstances as provided in
Sections 9.08 and 7.01) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and non-appealable judgment; 

(e)    shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or
representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the

other Loan Document or any other agreement, instrument or document, or the creation, perfection or priority of any Lien purported to be created by the Collateral Documents, (v) the value or the sufficiency of any Collateral, or (v) the
satisfaction of any condition set forth in Article IV or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to such Agent; and

Section 8.04    Reliance by Agents. Any Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument, document, direction 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 an appropriate Person. Any Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by an appropriate Person, and shall not incur any liability
for relying thereon. In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, any Agent may presume that such condition is satisfactory to such Lender unless
such Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. Any Agent may consult with legal counsel (who may include counsel for the Borrower), 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. 

  
 87 












 Section 8.05    Delegation of Duties. Without in any way limiting
Section 8.11, any Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more co-agents, sub-agents and/or attorneys-in-fact appointed by such Agent. Any Agent and any such co-agents, sub-agents and/or attorneys-in-fact may perform any and all of its duties and exercise its rights and powers by or through their
respective Related Parties. The exculpatory provisions of this Article shall apply to any such co-agents, sub-agents and/or attorneys-in-fact and to the Related Parties of each Agent and any such co-agents, sub-agents and/or attorneys-in-fact, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as an

 Section 8.06    Resignation of the Administrative Agent. The Administrative Agent may at any time give
notice of its resignation to the Lenders and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right to appoint a successor with the consent of the Borrower (not to be unreasonably withheld or
delayed), which shall be a financial institution with an office in the United States, or an Affiliate of any such financial institution with an office in the United States, and having a combined capital and surplus of at least U.S.$1.0 billion.
In the case of the resignation of the Administrative Agent, if no such successor shall have been appointed by the Required Lenders and the Borrower and shall have accepted such appointment within 30 days after the retiring Administrative Agent
gives notice of its resignation, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other
Loan Documents, (b) except for indemnity payments owed to the retiring Administrative Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each
Lender directly, until such time as the Required Lenders and the Borrower appoint a successor Administrative Agent as provided for above in this Section and (c) the Borrower and the Lenders agree that in no event shall the retiring
Administrative Agent or any of its Affiliates or any of their respective officers, directors, employees, agents advisors or representatives have any liability to the MLP Entity, the Borrower or any Subsidiary, any Lender or any other Person or
entity for damages of any kind, including, without limitation, direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of the failure of a successor Administrative
Agent to be appointed and to accept such appointment. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of
the retiring or retired Administrative Agent (other than any rights to indemnity payments owed to the retiring Administrative Agent), and the retiring or retired Administrative Agent shall be discharged from all of its duties and obligations
hereunder and under the other Loan Documents (if not already discharged therefrom as provided above in this Section). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless
otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article (including Section 8.10) and Section 9.05
shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while
the retiring Administrative Agent was acting as Administrative Agent. 

  
 88 













Section 8.07    Non-Reliance on the Agents; Other Lenders. Each Lender
acknowledges that it has, independently and without reliance upon any Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to
enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender or any of their Related Parties 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 Loan Document or any related agreement or any document furnished hereunder or thereunder.

federal, state or foreign bankruptcy, insolvency, receivership or similar law or any other judicial proceeding relative to the MLP Entity, the Borrower or any Restricted Subsidiary, the Administrative Agent (irrespective of whether the principal of
any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower or any other Loan Party) shall be entitled and empowered (but
not obligated), by intervention in such proceeding or otherwise: 
 (a)    to file and prove a claim for the whole
amount of the principal and interest owing and unpaid in respect of the Loans and all other Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the

Administrative Agent under Sections 2.05, 8.10, and 9.05) allowed in such judicial proceeding; and 
 (b)    to
collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver,
assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, if the Administrative Agent shall consent to the making
of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.05, 8.10 and 9.05. 
 Nothing contained herein shall be deemed to authorize the Administrative
Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender to authorize the Administrative Agent to vote in
respect of the claim of any Lender in any such proceeding and to subordinate any Lien on any Property granted to or held by the Administrative Agent under any Loan Document to the holder of any Permitted Lien.

authority provided for in the previous sentence.

(i) to reimburse each Agent, on demand, in the amount of its pro rata share (in accordance with the respective principal amounts of its applicable outstanding Loans)) of any expenses incurred for the benefit of the
Lenders by such Agent, including reasonable counsel fees and compensation of agents and employees paid for services rendered on behalf of the Lenders, which shall not have been reimbursed by the Borrower and (ii) to indemnify and hold harmless
each Agent and any of its directors, officers, employees or agents, on demand, in the amount of such pro rata share, from and against any and all liabilities, Taxes, obligations, losses, damages, penalties, actions,

way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by it or any of them under this Agreement or any other Loan Document, to the extent the same shall not have been reimbursed by the Borrower;
provided, that no Lender shall be liable to any Agent for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements to the extent found in a final nonappealable
judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Agent or any of its directors, officers, employees or agents.

 Section 8.12    Withholding. To the extent required by any
applicable law, the Administrative Agent may withhold from any payment to any Lender an amount equivalent to any applicable withholding Tax. If any payment has been made to any Lender by the Administrative Agent without the applicable withholding
Tax being withheld from such payment and the Administrative Agent has paid over the applicable withholding Tax to the Internal Revenue Service or any other Governmental Authority, or the Internal Revenue Service or any other Governmental Authority
asserts a claim that the Administrative Agent did not properly withhold Tax from amounts paid to or for the account of any Lender because the appropriate form was not delivered or was not properly executed or because such Lender failed to notify the
Administrative Agent of a change in circumstance which rendered the exemption from, or reduction of, withholding Tax ineffective or for any other reason, such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or
indirectly, by the Administrative Agent as Tax or otherwise, including any penalties or interest and together with all expenses (including legal expenses, allocated internal costs and
out-of-pocket expenses) incurred. 

Section 8.13    Enforcement. The authority to enforce rights and remedies hereunder and under the other Loan
Documents against any Loan Party or any of them shall be vested in, and all actions and proceedings at law in connection with such enforcement may be instituted and maintained by, the Administrative Agent or the Collateral Agent in accordance with
Section 7.01 and the Collateral Documents for the benefit of each Lender, as applicable; provided, that the foregoing shall not prohibit (a) the Administrative Agent or the Collateral Agent from exercising on its own behalf the
rights and remedies that inure to its benefit (solely in its capacity as Administrative Agent or Collateral Agent, as applicable) hereunder and under the other Loan Documents, (b) any Lender from exercising any enforcement rights, including

 Section 9.03    Binding Effect. This Agreement shall become
effective when it shall have been executed by the Borrower and the Agents and when the Administrative Agent shall have received copies hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall
be binding upon and inure to the benefit of the Borrower, the Agents and each Lender and their respective permitted successors and assigns. 

Section 9.04    Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of
each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section.
Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to the extent provided in paragraph (c) of
this Section), the Lenders, the Agents and, to the extent expressly contemplated hereby, the Related Parties of each of the Agents, the Lenders and the Indemnitees) any legal or equitable right, remedy or claim under or by reason of this Agreement.

 (b)    (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more
assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of the Loans at the time owing to it) without the prior written consent of any party other than Lender and applicable assignees. 

(ii)    Assignments shall be subject to the following additional conditions: 

(A)    each partial assignment shall be made as an assignment of a proportionate part of all the assigning
Lender’s rights and obligations under this Agreement; 
 (B)    the parties to each assignment
shall execute and deliver to the Administrative Agent an Assignment and Acceptance; 
 (C)    no such
assignment shall be made to the Borrower or any of its Affiliates; and 
 (D)    notwithstanding
anything to the contrary herein, no such assignment shall be made to a natural person. 

(iii)    Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section
below, from and after the effective date specified in each Assignment and Acceptance the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a
Lender under this Agreement, and the assigning 

  
 93 












 
Lender hereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Section 2.07 and 9.05. Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall not be effective as an assignment hereunder. 

(iv)    The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at
one of its offices a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time
to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Agents and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms
hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable
prior notice. 
 (v)    The parties to each assignment shall deliver to, and for the account of, the
Administrative Agent a processing and recordation fee in the amount of $3,500; provided, that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. Upon its
receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee and the processing and recordation fee referred to above (unless waived as set forth above), the Administrative Agent shall accept such Assignment
and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. 

(c)    (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or
more banks or other entities (other than the Borrower or any of its Affiliates) (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of the Loans owing
to it); provided, that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (C) the
Borrower, the Agents and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument (oral or written) pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain the sole right to exercise rights under and to enforce this Agreement and the other Loan Documents and to approve any amendment, modification or waiver of any provision
of this Agreement and the other Loan Documents; provided, that (x) such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in
Section 9.04(a)(i) or 

  
 94 












 
clause (i) through (vi) of the first proviso to Section 9.08(b) that affects such Participant and (y) no other agreement (oral or written) in respect of the foregoing with
respect to such Participant may exist between such Lender and such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits (and subject to the requirements and
limitations) of Section 2.07 to the same extent as if it were the Lender from whom it obtained its participation and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each
Participant also shall be entitled to the benefits of Section 9.06 as though it were a Lender, provided, that such Participant agrees to be subject to Section 2.08(c) as though it were a Lender. 

(ii)    A Participant shall not be entitled to receive any greater payment under Section 2.07 than the
applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent (which shall not be
unreasonably withheld or delayed) and the Borrower may withhold its consent if a Participant would be entitled to require greater payment than the applicable Lender under such Sections. A Participant that would be a
Non-U.S. Lender if it were a Lender shall not be entitled to the benefits of Section 2.07 to the extent such Participant fails to comply with Section 2.07(e) as though it were a Lender. 

(d)    Each Lender that sells a participation shall, acting solely for this purpose as a
non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the
Loans or other obligations under the Loan Documents (the “Participant Register”); provided, that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the
identity of any Participant or any information relating to a Participant’s interest in any loans or its other obligations under any Loan Document) except to the extent that such disclosure is necessary to establish that such loan or other
obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations or Section 1.163-5(b) of the Proposed Treasury Regulations
(or any amended or successor version). The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation
for all purposes of this Agreement notwithstanding any notice to the contrary. 
 (e)    Any Lender may at any time
pledge or assign a security interest in all or any portion of its rights under this Agreement and its promissory note, if any, to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank
or central bank having jurisdiction over such Lender, and this Section shall not apply to any such pledge or assignment of a security interest; provided, that no such pledge or assignment of a security interest shall release a Lender from any
of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto, and any such pledgee (other than a pledgee that is the Federal Reserve Bank or central bank) shall acknowledge in writing that its rights
under such pledge are in all respects subject to the limitations applicable to the pledging Lender under this Agreement or the other Loan Documents. 

  
 95 












 Section 9.05    Expenses; Indemnity. (a) The Borrower agrees
to pay all reasonable and documented out-of-pocket expenses incurred by the Agents and their respective Affiliates, in connection with the preparation of this Agreement
and the other Loan Documents, including the reasonable and documented out of pocket fees, charges and disbursements of counsel for the Administrative Agent (limited, in the case of legal fees and disbursements, to one primary external counsel of the
Administrative Agent, and one local external counsel of the Administrative Agent in each relevant jurisdiction), the administration of this Agreement (including expenses incurred in connection with due diligence and initial and ongoing Collateral
examination to the extent incurred with the reasonable prior approval of the Borrower and the reasonable fees, disbursements and charges for counsel in each jurisdiction where Collateral is located) and any amendments, modifications or waivers of
the provisions hereof or thereof (whether or not the Transactions hereby contemplated shall be consummated). The Borrower agrees to pay all reasonable and documented
out-of-pocket expenses incurred by the Agents and their respective Affiliates in connection with the enforcement and protection of their rights in connection with this
Agreement and the other Loan Documents, in connection with the Loans made hereunder, including the reasonable fees, charges and disbursements of counsel for the Agents or the Lenders (including external counsel and the reasonable and documented
allocated costs of internal counsel for the Agents or any Lender); provided, that, absent any conflict of interest, the Agents and Lenders shall not be entitled to indemnification for the fees, charges or disbursements of more than one
counsel in each jurisdiction. 
 (b)    The Borrower agrees to indemnify the Agents, each Lender and each Related Party
of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, penalties, claims, damages, liabilities and related expenses, including
reasonable and documented counsel fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (i) the execution or delivery of this Agreement or any other Loan
Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto and thereto of their respective obligations thereunder or the consummation of the Transactions and the other transactions contemplated
hereby or thereby, (ii) any Loan or the use of the proceeds of the Loans or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not the Borrower, its Subsidiaries, the MLP Entity, any
Indemnitee or any other Person initiated or is a party thereto; provided, that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, penalties, claims, damages, liabilities or related expenses are
determined by a final, nonappealable judgment rendered by a court of competent jurisdiction (A) to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee (or any of such Indemnitee’s Related Parties) or
(B) to arise from disputes solely among Indemnitees if such dispute (i) does not involve any action or inaction by the MLP Entity, the Borrower or any Subsidiary and (ii) is not related to any action by an Indemnitee in its capacity
as Agent. Subject to and without limiting the generality of the foregoing sentence, the Borrower agrees to indemnify each Indemnitee against, and hold each Indemnitee harmless from, any and all losses, penalties, claims, damages, liabilities and
related expenses, including reasonable and documented counsel or consultant fees, charges and disbursements, incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (A) any Environmental Event
or Environmental Claim related in any way to the Borrower or any of its Subsidiaries, or (B) any actual or alleged presence, Release or threatened Release of 

  
 96 












 
Hazardous Materials at, under, on or from any Real Property currently or formerly owned, leased or operated by the Borrower or any of its Subsidiaries or by any predecessor of the Borrower or any
of its Subsidiaries, or any property at which the Borrower or any of its Subsidiaries has sent Hazardous Materials for treatment, storage or disposal; provided, that such indemnity shall not, as to any Indemnitee, be available to the extent
that such losses, penalties, claims, damages, liabilities or related expenses have resulted from the gross negligence, bad faith or willful misconduct of such Indemnitee, as determined by a final and nonappealable judgment in a court of competent
jurisdiction. In the event of any of the foregoing, each Indemnitee shall be indemnified whether or not such amounts are caused by or arising, in whole or in part, out of the comparative, contributory or sole negligence of any Indemnitee (except to
the extent of gross negligence as specified above). In no event shall any Indemnitee be liable to the MLP Entity, the Borrower, any Subsidiary Loan Party, or any other Subsidiary, or shall the MLP Entity, the Borrower or any Subsidiary be liable to
any Indemnitee, for any consequential, indirect, special or punitive damages; provided, however, that nothing in this sentence shall limit the Borrower’s indemnification obligations set forth in this Section 9.05. No
Indemnitee shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed to such unintended recipients by such Indemnitee through telecommunications, electronic or other information
transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby other than for direct or actual damages resulting from the gross negligence, bad faith, or willful misconduct of
such Indemnitee as determined by a court of competent jurisdiction. The provisions of this Section 9.05 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the
transactions contemplated hereby, the repayment of any of the Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of any Agent or any
Lender. All amounts due under this Section 9.05 shall be payable on written demand accompanied by reasonable documentation with respect to any reimbursement, indemnification or other amount requested. 

(c)    This Section 9.05 shall not apply to Taxes. 

Section 9.06    Right of Set-off. If an Event of Default shall have occurred
and be continuing, each Lender and any Affiliate of a Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional
or final) at any time held and other indebtedness at any time owing by such Lender or such Affiliate of a Lender to or for the credit or the account of any Loan Party or any Subsidiary that is not a Foreign Subsidiary, against any and all
obligations of the Loan Parties, now or hereafter existing under this Agreement or any other Loan Document held by such Lender or such Affiliate of a Lender, irrespective of whether or not such Lender or such Affiliate of a Lender shall have made
any demand under this Agreement or such other Loan Document and although the obligations may be unmatured. The rights of each Lender and each Affiliate of a Lender under this Section 9.06 are in addition to other rights and remedies (including
other rights of set-off) that such Lender or such Affiliate of a Lender may have. 

Section 9.07    Applicable Law. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN AS EXPRESSLY SET FORTH IN
OTHER LOAN DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 

  
 97 












 Section 9.08    Waivers; Amendment. (a) No failure or delay of
the Agents or any Lender in exercising any right, power or remedy hereunder or under any Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy, or any abandonment or
discontinuance of steps to enforce such a right, power or remedy, preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The rights, powers and remedies of the Agents and the Lenders hereunder and under
the other Loan Documents 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 any other Loan Document or consent to any departure by the MLP Entity, the
Borrower or any Subsidiary Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, 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 the MLP Entity, the Borrower or any Subsidiary Loan Party in any case shall entitle such Person to any other or further notice or demand in similar or other circumstances. 

(b)    Neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be waived, amended or
modified except (x) in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders (or the Administrative Agent with the consent of the Required Lenders) and (y) in
the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by each Loan Party party thereto and the Collateral Agent (acting at the written direction of the Administrative Agent) and consented to by the
Required Lenders; provided, that no such agreement shall 
 (i)    decrease or forgive the
principal amount of, or extend the final maturity of, or decrease the rate of interest on any Loan, without the prior written consent of each Lender directly affected thereby; provided, that any amendment to the financial covenant definitions
in this Agreement shall not constitute a reduction in the rate of interest for purposes of this clause (i) and provided, further, that, any waiver of all or a portion of any post-default increase in interest rates shall be
effective upon the consent of the Required Lenders, 
 (ii)    increase or extend the Loans of any Lender
or decrease the fees payable to any Lender without the prior written consent of such Lender (it being understood that waivers or modifications of conditions precedent, covenants, Defaults or Events of Default shall not constitute an increase in or
extension of the Loans of any Lender), 
 (iii)    extend any date on which payment of the principal
amount of any Loan or interest on any Loan or any Fees or any other payment hereunder is due, without the prior written consent of each Lender adversely affected thereby, 

(iv)    change the order of application of any amounts from the application thereof set forth in the
applicable provisions of Section 2.08(b), Section 2.08(c) or Section 9.21 or change any provision hereof that establishes the pro rata treatment 

  
 98 












 
among the Lenders in a manner that would by such change alter the pro rata sharing or other pro rata treatment of the Lenders, without the prior written consent of each Lender adversely
affected thereby, 
 (v)    amend or modify the provisions of this Section 9.08 or any requirement
of Article IV or the definition of the terms “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant
any consent hereunder, without the prior written consent of each Lender, and 
 (vi)    release all or
substantially all the Collateral or release all or substantially all of the value of the Guarantees of the MLP Entity and the Subsidiary Loan Parties without the prior written consent of each Lender (except, in the case of any Subsidiary Loan Party,
to the extent of a release in connection with a transaction expressly permitted in Sections 6.02 or 6.05); 
 provided, further, that no
such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Collateral Agent hereunder or under the other Loan Documents, without the prior written consent of such Administrative Agent or Collateral
Agent, as applicable. Each Lender shall be bound by any waiver, amendment or modification authorized by this Section 9.08 and any consent by any Lender pursuant to this Section 9.08 shall bind any assignee of such Lender. 

(c)    With the consent of each Loan Party, as applicable, Administrative Agent and/or Collateral Agent may (in their
respective sole discretion, or shall, to the extent required by any Loan Document) enter into any amendment, modification or waiver of any Loan Document, or enter into any new agreement or instrument, to effect the granting, perfection, protection,
expansion or enhancement of any security interest in any Collateral or additional property to become Collateral for the benefit of the Secured Parties, or as required by local law to give effect to, or protect any security interest for the benefit
of the Secured Parties, in any property or so that the security interests therein comply with applicable law. 

(d)    Notwithstanding the foregoing, any Loan Document may be amended, modified, supplemented or waived with the written
consent of the Administrative Agent and the Borrower without the need to obtain the consent of any Lender (i) in accordance with Sections 6.10, 6.11 and 6.12 or (ii) if such amendment, modification, supplement or waiver is executed and
delivered in order to cure an ambiguity, omission, mistake or defect in such Loan Document; provided, that in no event will the Administrative Agent be required to substitute its judgment for the judgment of the Lenders or the Required
Lenders, and the Administrative Agent may in all circumstances seek the approval of the Required Lenders, the affected Lenders or all Lenders in connection with any such amendment, modification, supplement or waiver. 

Section 9.09    Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the
applicable interest rate, together with all fees and charges that are treated as interest under applicable law (collectively, the “Charges”), as provided for herein or in any other document executed in connection herewith, or
otherwise contracted for, charged, received, taken or reserved by any Lender, shall exceed the maximum lawful rate (the “Maximum Rate”) that 

  
 99 












 
may be contracted for, charged, taken, received or reserved by such Lender in accordance with applicable law, the rate of interest payable hereunder, together with all Charges payable to such
Lender, shall be limited to the Maximum Rate, provided, that such excess amount shall be paid to such Lender on subsequent payment dates to the extent not exceeding the legal limitation. 

Section 9.10    Entire Agreement. This Agreement, the other Loan Documents and the agreements regarding certain Fees
referred to herein constitute the entire contract between the parties relative to the subject matter hereof. Any previous agreement among or representations from the parties or their Affiliates with respect to the subject matter hereof is superseded
by this Agreement and the other Loan Documents. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any party other than the parties hereto and thereto any rights, remedies, obligations or
liabilities under or by reason of this Agreement or the other Loan Documents. 
 Section 9.11    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 OR ANY
OF THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (i) 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 (ii) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
SECTION 9.11. 
 Section 9.12    Severability. In the event any one or more of the provisions contained in this
Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired
thereby. 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 9.13    Counterparts. This Agreement may be executed in one or more counterparts, each of
which shall constitute an original but all of which, when taken together, shall constitute but one contract, and shall become effective as provided in Section 9.03. Delivery of an executed counterpart to this Agreement by facsimile transmission
or an electronic transmission of a PDF copy thereof shall be as effective as delivery of a manually signed original. Any such delivery shall be followed promptly by delivery of the manually signed original.

 Section 9.15    Jurisdiction; Consent to Service of Process.
(a) Each of the Borrower, the Agents and the Lenders hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of any New York State court or federal court of the United States of America sitting
in New York County, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such federal court. The Borrower further irrevocably
consents to the service of process in any action or proceeding in such courts by the mailing thereof by any parties thereto by registered or certified mail, postage prepaid, to the Borrower at the address specified for the Loan Parties in
Section 9.01. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in
this Agreement (other than Section 8.09) shall affect any right that any Lender may otherwise have to bring any action or proceeding relating to this Agreement or the other Loan Documents against the Borrower or any Loan Party or their
properties in the courts of any jurisdiction. 
 (b)    Each of the Borrower, the Agents and the Lenders hereby
irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this
Agreement or the other Loan Documents in any New York State or federal court sitting in New York County. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any such court. 
 Section 9.16    Confidentiality. Each of the Lenders
and each of the Agents agrees that it shall maintain in confidence any information relating to the Borrower and its Subsidiaries and their respective Affiliates furnished to it by or on behalf of the Borrower or the other Loan Parties or such
Subsidiary or Affiliate (other than information that (x) has become generally available to the public other than as a result of a disclosure by such party in breach of this Agreement, (y) has been independently developed by such Lender or
such Agent without violating this Section 9.16 or (z) was available to such Lender or such Agent from a third party having, to such Person’s actual knowledge, no obligations of confidentiality to the Borrower or any of its
Subsidiaries or any such Affiliate) and shall not reveal the same other than to its directors, trustees, officers, employees, agents and advisors with a need to know or to any Person that approves or administers the Loans on behalf of such Lender
(so long as each such Person shall have been instructed to keep the same confidential in accordance with this Section 9.16), except: (i) to the extent necessary to comply with law or any legal process or the regulatory (including
self-regulatory) or supervisory requirements of any Governmental Authority (including bank examiners), the National Association of Insurance Commissioners or of any securities exchange on which securities of the disclosing party or any Affiliate of

Affiliates, and their respective directors, officers, employees and agents, including accountants, legal counsel and other advisors (so long as each such Person shall have been instructed to keep the same confidential in


  
 101 












 
accordance with this Section 9.16), (iv) to any Agent, any other Lender or any other party of any Loan Document and the Affiliates of each, (v) in connection with the exercise of
any remedies under any Loan Document or in order to enforce its rights under any Loan Document in a legal proceeding, (vi) to any prospective assignee of, or prospective Participant in, any of its rights under this Agreement (so long as such
Person shall have been instructed to keep the same confidential in accordance with this Section 9.16 or on terms at least as restrictive as those set forth in this Section 9.16), (vii) to any direct or indirect contractual
counterparty in Swap Agreements or such contractual counterparty’s professional advisor (so long as each such contractual counterparty agrees to be bound by the provisions of this Section 9.16 or on terms at least as restrictive as those
set forth in Section 9.16 and each such professional advisor shall have been instructed to keep the same confidential in accordance with this Section 9.16), (viii) with the consent of the Borrower and (ix) on a confidential basis
to any rating agency in connection with rating the Borrower or its Subsidiaries or this Agreement. If a Lender or an Agent is requested or required to disclose any such information (other than to its bank examiners and similar regulators, or to
internal or external auditors) pursuant to or as required by law or legal process or subpoena, then, to the extent reasonably practicable, it shall give prompt notice thereof to the Borrower so that the Borrower may seek an appropriate protective
order and such Lender or Agent will cooperate to the extent reasonably possible and legally permissible with the Borrower (or the applicable Subsidiary or Affiliate) in seeking such protective order. 

Section 9.17    Communications. (a) Delivery. 

(i)    Each Loan Party hereby agrees that it will use all reasonable efforts to provide to the
Administrative Agent all information, documents and other materials that it is obligated to furnish to the Administrative Agent pursuant to this Agreement and any other Loan Document, including, without limitation, all notices, requests, financial
statements, financial and other reports, certificates and other information materials, but excluding any such communication that (A) relates to the payment of any principal or other amount due under this Agreement prior to 5:00 p.m., New
York City time on the scheduled date therefor, (B) provides notice of any Default or Event of Default under this Agreement or (C) is required to be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or
any extension of credit hereunder (all such non-excluded communications collectively, the “Communications”), by transmitting the Communications in an electronic/soft medium in a format
reasonably acceptable to the Administrative Agent at the address referenced in Section 9.01(a)(ii). Nothing in this Section 9.17 shall prejudice the right of the Agents, the Lenders or any Loan Party to give any notice or other
communication pursuant to this Agreement or any other Loan Document in any other manner specified in this Agreement or any other Loan Document. 

(ii)    Each Lender agrees that notice to it (as provided in the next sentence) specifying that the
Communications have been posted to the Platform (as defined below) shall constitute effective delivery of the Communications to such Lender for purposes of the Loan Documents. Each Lender agrees (A) to notify the Administrative Agent in writing
(including by electronic communication) from time to time of such Lender’s e-mail address to which the foregoing notice may be sent by electronic transmission and (B) that the foregoing notice may be
sent to such e-mail address. 

  
 102 












 (b)    Posting. Each Loan Party further agrees that the
Administrative Agent may make the Communications available to the Lenders by posting the Communications on Intralinks or a substantially similar electronic transmission system (the “Platform”). The Borrower hereby acknowledges that
(i) the Administrative Agent will make available to the Lenders materials and/or information provided by or on behalf of the Borrower hereunder (collectively, “Borrower Materials”) by posting the Borrower Materials on the
Platform and (ii) certain of the Lenders (each, a “Public Lender”) may have personnel who do not wish to receive material non-public information with respect to the Borrower or its
Affiliates, or the respective securities of any of the foregoing, and who may be engaged in investment and other market-related activities with respect to such Persons’ securities. The Borrower hereby agrees that it will use commercially
reasonable efforts to identify that portion of the Borrower Materials that may be distributed to the Public Lenders and that (w) all such Borrower Materials shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall
mean that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking Borrower Materials “PUBLIC,” the Borrower shall be deemed to have authorized the Administrative Agent and the Lenders to treat
such Borrower Materials as not containing any material non-public information (although it may be sensitive and proprietary) with respect to the Borrower or its Affiliates or their respective securities for
purposes of United States federal and state securities laws; (y) all Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform designated “Public Side Information;” and
(z) the Administrative Agent shall be entitled to treat any Borrower Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform not designated “Public Side Information.”
Notwithstanding the foregoing, the Borrower shall not be under any obligation to mark any Borrower Materials “PUBLIC” to the extent the Borrower determines that such Borrower Materials contain material
non-public information with respect to the Borrower or its Affiliates or their respective securities for purposes of United States federal and state securities laws. 

(c)    Platform. The Platform is provided “as is” and “as available.” The Agent Parties
(as defined below) do not warrant the accuracy or completeness of the Communications, or the adequacy of the Platform and expressly disclaim liability for errors or omissions in the Communications. No warranty of any kind, express, implied or
statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by any
Agent Party in connection with the Communications or the Platform. In no event shall the Administrative Agent, the Collateral Agent or any of its or their Affiliates or any of their respective officers, directors, employees, agents advisors or
representatives (collectively, “Agent Parties”) have any liability to the Loan Parties, any Lender or any other Person or entity for damages of any kind, including, without limitation, direct or indirect, special, incidental or
consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of any Loan Party’s or the Administrative Agent’s or the Collateral Agent’s transmission of communications through the internet, except to
the extent the liability of any Agent Party is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted primarily from such Agent Party’s gross negligence or willful
misconduct. 

  
 103 












 Section 9.18    Release of Liens and Guarantees. (a) In the
event that (i) the Borrower or any Subsidiary Loan Party conveys, sells, leases, assigns, transfers or otherwise disposes of all or any portion of its assets (including the Equity Interests of any of its Subsidiaries) to a Person that is not
(and is not required to become) a Loan Party in a transaction not prohibited by the Loan Documents (other than any sale or conveyance of any assets to Eddy County in connection with the IRB Transactions), (ii) any Restricted Subsidiary becomes an
Unrestricted Subsidiary (other than any Included Entity, any Ohio Joint Venture or, from and after the Opt-In Time, the Double E Joint Venture) or (iii) any Subsidiary ceases to be a Revolver Loan Party,
then, in any of such cases, the Administrative Agent and the Collateral Agent shall promptly (and the Lenders hereby authorize the Administrative Agent and the Collateral Agent to) take such action and execute any such documents as may be reasonably
requested by the Borrower and at the Borrower’s sole cost and expense to release any Liens created by any Loan Document in respect of such Equity Interests, Subsidiary Loan Party or assets that are the subject of such disposition, release any
Liens created by any Loan Document in respect of Equity Interests of any Restricted Subsidiary that becomes an Unrestricted Subsidiary (other than any Included Entity, any Ohio Joint Venture or, from and after the
Opt-In Time, the Double E Joint Venture), and release any Guarantees of the Obligations and release any Liens granted to secure the Obligations, in each case by a Person that ceases to be a Subsidiary of the
Borrower or that ceases to be a Subsidiary Loan Party as a result of a transaction described above. Any representation, warranty or covenant contained in any Loan Document relating to any such Equity Interests or assets shall no longer be deemed to
be made once such Equity Interests or assets are so conveyed, sold, leased, assigned, transferred or disposed of. Any sale or conveyance of any assets to Eddy County in connection with the IRB Transactions shall be subject to all Liens thereon
created under the Loan Documents, and such Liens created under the Loan Documents shall continue in effect after such sale or conveyance. 

(b)    When all the Obligations are paid in full in cash (other than contingent indemnification obligations), the
Collateral Documents, the Guarantees made therein, the Security Interest (as defined therein) and all other security interests granted thereby shall terminate, and each Loan Party shall automatically be released from its obligations thereunder and
the security interests in the Collateral granted by any Loan Party shall automatically be released. At such time, the Administrative Agent and the Collateral Agent (at the written direction of the Administrative Agent) agree to take such actions as
are reasonably requested by the Borrower at the Borrower’s expense to evidence and effectuate such termination and release of the Guarantees, Liens and security interests created by the Loan Documents. 

(c)    Authorizations for each release and termination specified in this Section 9.18 shall be required only to the
extent required by Section 8.10. 
 Section 9.19    Judgment. If for the purposes of obtaining judgment in any
court it is necessary to convert a sum due hereunder in one currency into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with
normal banking procedures the Administrative Agent could purchase the first mentioned currency with such other currency at the Administrative Agent’s office on the Business Day preceding that on which final judgment is given. 

Section 9.20    No Fiduciary Duty. Each Agent, each Lender and their respective Affiliates (collectively, solely for
purposes of this paragraph, the “Lenders”), may have economic interests that conflict with those of the MLP Entity, the Borrower and the Subsidiaries of the Borrower. 

  
 104 












 
The Borrower hereby agrees that subject to applicable law, nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other
implied duty between the Lenders and the Loan Parties, their equity holders or their Affiliates. The Borrower hereby acknowledges and agrees that (i) the transactions contemplated by the Loan Documents are
arm’s-length commercial transactions between the Lenders, on the one hand, and the Loan Parties, on the other, (ii) in connection therewith and with the process leading to such transaction none of
the Lenders is acting as the agent or fiduciary of any Loan Party, its management, equity holders, creditors or any other person, (iii) no Lender has assumed an advisory or fiduciary responsibility in favor of any Loan Party with respect to the
transactions contemplated hereby or the process leading thereto (irrespective of whether any Lender or any of its Affiliates has advised or is currently advising such Loan Party on other matters) or any other obligation to any Loan Party except the
obligations expressly set forth in the Loan Documents, (iv) the Borrower and each other Loan Party has consulted its own legal and financial advisors to the extent it has deemed appropriate and (v) the Lenders may be engaged in a broad
range of transactions that involve interests that differ from those of the Borrower and its Affiliates and no Lender has an obligation to disclose any such interests to the Borrower or its Affiliates. The Borrower further acknowledges and agrees
that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto. 

Section 9.21    Application of Funds. Subject to the Intercreditor Agreement, after the exercise of remedies provided
for in Section 7.01 (or after the Loans have automatically become immediately due and payable), any amounts received by the Administrative Agent from the Collateral Agent pursuant to any Collateral Document and any other amounts received by the
Administrative Agent on account of the Loan Document Obligations shall be applied by the Administrative Agent in the following order: 

(a)    First, to payment of that portion of the Loan Document Obligations constituting Fees, indemnities, expenses
and other amounts (other than principal and interest but including Fees, charges and disbursements of counsel to the Administrative Agent and the Collateral Agent) payable to the Administrative Agent and the Collateral Agent in their respective
capacities as such; 
 (b)    Second, to payment of that portion of the Loan Document Obligations constituting
Fees, indemnities and other amounts (other than principal and interest) payable to the Lenders (including Fees, charges and disbursements of counsel to the respective Lenders) arising under the Loan Documents, ratably among them in proportion to the
respective amounts described in this clause Second payable to them; 
 (c)    Third, to payment of that
portion of the Loan Document Obligations constituting accrued and unpaid interest on the Loans and other Obligations arising under the Loan Documents, ratably among the Lenders in proportion to the respective amounts described in this clause
Third payable to them; and 
 (d)    Last, the balance, if any, after all of the Loan Document Obligations
have been indefeasibly paid in full, to the Borrower or as otherwise required by Law. 
 Section 9.22    Intended Third
Party Beneficiaries. The Collateral Agent is an intended third party beneficiary of Article VIII and Section 9.05 hereof.

 FOR VALUE RECEIVED, the undersigned, SUMMIT MIDSTREAM HOLDINGS, LLC, a Delaware limited liability company (the
“Borrower”), HEREBY PROMISES TO PAY to [NAME OF LENDER] (the “Lender”) or its registered assigns for the account of its applicable lending office the principal amount of the Loans owing to the Lender by the Borrower
pursuant to the Term Loan Credit Agreement (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”) dated as of May 28, 2020, among the Borrower, the LENDERS party thereto from time
to time and SMP TopCo, LLC, as administrative agent (in such capacity, together with any successor administrative agent, the “Administrative Agent”). Terms defined in the Credit Agreement are used herein with the same meanings. 

The Borrower promises to pay to the Lender or its registered assigns interest on the unpaid principal amount of the Loans represented by this
Promissory Note and advanced to the Borrower from the date of such Loan until such principal amount is paid in full, at such interest rates, and payable at such times, as are specified in the Credit Agreement. 

Both principal and interest are payable in U.S. dollars to the Administrative Agent for the benefit of the Lenders as set forth in the Credit
Agreement. The Loans represented by this Promissory Note advanced to the Borrower and the maturity thereof, and all payments made on account of principal thereof, shall be recorded by the Lender and, prior to any transfer hereof, endorsed on the
grid attached hereto, which is part of this promissory note (this “Promissory Note”); provided, however, that the failure of the Lender to make any such recordation or endorsement shall not affect the Obligations of
the Borrower under this Promissory Note. 
 This Promissory Note is one of the promissory notes referred to in Section 2.02(e) of the
Credit Agreement and is entitled to the benefits of the Credit Agreement. The Credit Agreement, among other things, (i) provides for the making of Loans by the Lenders to or for the benefit of the Borrower, the indebtedness of the Borrower
resulting from the Loans being, on request of a Lender, evidenced by such promissory notes, and (ii) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events and also for prepayments on account of
principal hereof prior to the maturity hereof upon the terms and conditions therein specified. The obligations of the Borrower under this Promissory Note and the other Loan Documents, and the obligations of the other Loan Parties under the Loan
Documents, are secured by the Collateral as provided in the Loan Documents. 
 The Borrower, for itself, its successors and assigns, hereby
waives diligence, presentment, protest and demand and notice of protest, demand, dishonor and non-payment of this Promissory note. 

This Promissory Note shall be governed by, and construed in accordance with, the laws of the State of New York and is entered into as of the
date first written above.
