“asset” and “property” shall be construed to have the same meaning and effect and to refer to any and all tangible and intangible assets and properties, including cash, securities, accounts and contract rights. 
 Section 1.04 Accounting Terms; GAAP. Except as otherwise expressly provided herein, all terms of an accounting or financial nature shall be
construed in accordance with GAAP, as in effect from time to time; provided that, if the Borrower notifies the Administrative Agent that the Borrower requests an amendment to any provision hereof to eliminate the effect of any change
occurring after the date hereof in GAAP or in the application thereof on the operation of such provision (or if the Administrative Agent notifies the Borrower that the 

  

 -19- 

 
Required Lenders request an amendment to any provision hereof for such purpose), regardless of whether any such notice is given before or after such change
in GAAP or in the application thereof, then such provision shall be interpreted on the basis of GAAP as in effect and applied immediately before such change shall have become effective until such notice shall have been withdrawn or such provision
amended in accordance herewith. 
 ARTICLE II 
 The Term Loans 
 Section 2.01 Commitments. Subject to the terms and conditions set forth
herein, each Lender agrees to make a single advance term Loan in dollars to the Borrower on the Effective Date in an aggregate principal amount equal to such Lender’s Commitment. The Commitments are not revolving and amounts repaid may not be
re-borrowed. 
 Section 2.02 Loans and Tranches. (a) Each Loan shall be made on the Effective Date by the Lenders ratably in
accordance with their respective Commitments. The failure of any Lender to make its Loan shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be
responsible for any other Lender’s failure to make its Loan as required. 
 (b) Subject to Section 2.12, the Loans shall be
comprised of ABR Tranches and/or Eurodollar Tranches as the Borrower may request in accordance herewith. Each Lender at its option may fund any portion of its Loan consisting of a Eurodollar Tranche by causing any domestic or foreign branch or
Affiliate of such Lender to fund such Tranche; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Lender’s Loan in accordance with the terms of this Agreement 
 (c) At the commencement of each Interest Period for any Eurodollar Tranche, such Tranche shall be in an aggregate amount that is an integral multiple of
$1,000,000 and not less than $5,000,000 (in each case, determined on the date by which the Borrowing Request or Interest Election Request is required to be delivered pursuant to Section 2.03 or Section 2.05, respectively). At the time that
any ABR Tranche is made, such Tranche shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. Tranches of more than one Type may be outstanding at the same time; provided that there shall not at
any time be more than a total of five Eurodollar Tranches outstanding. 
 (d) Notwithstanding any other provision of this Agreement, the
Borrower shall not be entitled to request, or to elect to convert or continue, any Tranche if the Interest Period requested with respect thereto would end after the Maturity Date. 
 Section 2.03 Requests for the Loans. To request the Loans on the Effective Date, the Borrower shall deliver a Borrowing Request in substantially
the form of Exhibit B and signed by the Borrower, to the Administrative Agent, not later than 12:00 noon, New York City time, (a) in the case of a Eurodollar Tranche, three Business Days before the Effective Date or (b) in the case of an
ABR Tranche, on the Effective Date. The Borrowing Request shall be irrevocable once 

  

 -20- 

 
given. The Borrowing Request shall specify the following information in compliance with Section 2.02: 
 (i) the aggregate amount of the requested Loans; 
 (ii) the proposed funding date of the Loans, which shall be the Effective Date and a Business Day; 
 (iii) whether any portion of
such Loans is to be an ABR Tranche or a Eurodollar Tranche; 
 (iv) in the case of a Eurodollar Tranche, the initial Interest Period to be
applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and 
 (v) the location
and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.04. 
 If no
election as to the Type of Tranche is specified, then the requested Tranche shall be an ABR Tranche. If no Interest Period is specified with respect to any requested Eurodollar Tranche, then the Borrower shall be deemed to have selected an Interest
Period of one month’s duration. Promptly following receipt of the Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be
made. 
 Section 2.04 Funding of the Loans. (a) Each Lender shall make available the Loan to be made by it hereunder on the
Effective Date by wire transfer of immediately available funds in dollars by 2:00 p.m., New York City time, to the account of the Administrative Agent designated by it for such purpose by notice to the Lenders. The Administrative Agent will make
such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the Borrowing Request.

 (b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed time of funding of the Loans on the
Effective Date that such Lender will not make available to the Administrative Agent such Lender’s Loan, the Administrative Agent may assume that such Lender has made its Loan available on such date in accordance with paragraph (a) of this
Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its Loan available to the Administrative Agent, then the applicable Lender and the Borrower
severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to
the Administrative Agent, at (i) in the case of such Lender, 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 or (ii) in
the case of the Borrower, the interest rate applicable to ABR Tranches. If such Lender 

  

 -21- 

 
pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan. 
 Section 2.05 Interest Elections. (a) Each Tranche initially shall be of the Type specified in the Borrowing Request and, in the case of a
Eurodollar Tranche, shall have an initial Interest Period as specified in the Borrowing Request. Thereafter, the Borrower may elect to convert such Tranche to a different Type or to continue such Tranche and, in the case of a Eurodollar Tranche, may
elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Tranche, in which case each such portion shall be allocated ratably among the Lenders
holding the portion of such Loans comprising such Tranche, and each portion of such Loans shall be considered a separate Tranche. 
 (b) To
make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone: (i) in the case of a Eurodollar Tranche, not later than 12:00 noon, New York City time, three Business Days before the
first day of the Interest Period related to such Eurodollar Tranche; and (ii) in the case of an ABR Tranche, not later than 12:00 noon, New York City time, on the same Business Day of the proposed conversion or continuation. Each such
telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by
the Borrower. 
 (c) Each telephonic and written Interest Election Request shall specify the following information in compliance with
Section 2.02: 
 (i) the Tranche to which such Interest Election Request applies and, if different options are being
elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Tranche (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each
resulting Tranche) 
 (ii) the effective date of the election made pursuant to such Interest Election Request, which shall be
a Business Day; 
 (iii) whether the resulting Tranche is to be an ABR Tranche or a Eurodollar Tranche; and 
 (iv) if the resulting Tranche is a Eurodollar Tranche, the Interest Period to be applicable thereto after giving effect to such election,
which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such Interest Election Request requests a
Eurodollar Tranche but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 
  

 -22- 

 (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise
each Lender of the details thereof and of such Lender’s portion of each resulting Tranche. 
 (e) If the Borrower fails to deliver a
timely Interest Election Request with respect to a Eurodollar Tranche prior to the end of the Interest Period applicable thereto, then, unless such Tranche is repaid as provided herein, at the end of such Interest Period, such Tranche shall be
converted to an ABR Tranche. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an
Event of Default is continuing (i) no outstanding Tranche may be converted to or continued as a Eurodollar Tranche and (ii) unless repaid, each Eurodollar Tranche shall be converted to an ABR Tranche at the end of the Interest Period
applicable thereto. 
 Section 2.06 Termination of Commitments. Unless previously terminated, the Commitments shall terminate at 4:00
p.m., New York City time, on the Effective Date. 
 Section 2.07 Repayment of Loans; Evidence of Debt. 
 (a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of
each Loan on the Maturity Date. 
 (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 the 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, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder for the account of the Lenders and each Lender’s share thereof. 
 (d) The entries made in the accounts maintained pursuant to
paragraph (a) or (c) of this Section shall be prima facie evidence 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 in accordance with the terms of this Agreement. 
 (e) Any Lender may request that the Loan made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender a promissory note payable to the order of such
Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loan evidenced by such promissory note and interest thereon shall at all times be 

  

 -23- 

 
represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note,
to such payee and its registered assigns). 
 Section 2.08 Optional Prepayment of Loans. (a) Subject to any break funding costs
payable pursuant to Section 2.14, the Borrower shall have the right at any time and from time to time to prepay any Tranche in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section. 
 (b) The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a Eurodollar Tranche, not later than 11:00 a.m., New York City time, three Business Days before the date of prepayment and (ii) in the case of prepayment of an ABR Tranche, not later than 11:00 a.m., New York City time, one
Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Tranche or portion thereof to be prepaid. Promptly following receipt of any such notice relating
to a Tranche, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Tranche shall be in an amount that would be permitted in the case of an advance of a Tranche of the same Type as provided in
Section 2.02. Each prepayment of a Tranche shall be applied ratably to the portion of the Loans included in the prepaid Tranche. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.11 and any break
funding payments required by Section 2.14. 
 Section 2.09 Mandatory Prepayment of Loans. 
 (a) If the MLP or any of its Restricted Subsidiaries (including the Borrower) shall issue or sell any Equity Interests, Hybrid Equity Securities or
Convertible Securities, or issue, sell or incur any Indebtedness (other than Excepted Indebtedness), then as soon as practicable and in any event no later than the Business Day following the Business Day on which the MLP or such Restricted
Subsidiary receives the Net Cash Proceeds therefrom, an amount equal to 100% of the Net Cash Proceeds therefrom shall be applied toward the prepayment of the Loans. 
 (b) If the Acquisition has not been consummated on or before March 31, 2008, then, on March 31, 2008, the Borrower shall prepay 100% of the principal amount of all Loans then outstanding. 
 (c) Amounts to be applied in connection with prepayments made pursuant to this Section 2.09 shall be applied to the prepayment of the Loans ratably.
The application of any prepayment pursuant to this Section 2.09 shall be made, first, to ABR Tranches and, second, to Eurodollar Tranches. Each prepayment of the Loans under this Section 2.09 shall be accompanied by accrued interest to the
extent required by Section 2.11 and any break funding costs pursuant to Section 2.14. 
  

 -24- 

 (d) All prepayments of Loans pursuant to this Section 2.09 shall be without the payment by the
Borrower of any premium or penalty except for break funding costs payable pursuant to Section 2.14. 
 Section 2.10 Fees.

 (a) If the principal of any Lender’s Loan is outstanding on April 1, 2008, then the Borrower agrees to pay to the Administrative
Agent, for the account of such Lender, a fee in an amount equal to 0.050% on the principal amount of such Lender’s Loan that is outstanding on such date, which fee shall be payable on April 1, 2008. 
 (b) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon
between the Borrower and the Administrative Agent. 
 (c) All fees payable hereunder shall be paid in dollars on the dates due, in
immediately available funds, to the Administrative Agent. Fees paid shall not be refundable under any circumstances. 
 Section 2.11
Interest. (a) The portion of each Loan comprising each ABR Tranche shall bear interest at the Alternate Base Rate plus the Applicable Rate. 
 (b) The portion of each Loan comprising each Eurodollar Tranche shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Tranche plus the Applicable Rate. 
 (c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid
when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, 2% plus the rate
otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, 2% plus the rate applicable to ABR Tranches as provided in paragraph (a) of this Section. 
 (d) Accrued interest on each Tranche shall be payable in arrears on each Interest Payment Date for such Tranche; provided that (i) interest
accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Tranche (other than a prepayment of an ABR Tranche prior to the Maturity Date), accrued interest on the
principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Tranche prior to the end of the current Interest Period therefor, accrued interest on
such Tranche shall be payable on the effective date of such conversion. 
 (e) All interest hereunder shall be computed on the basis of a
year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each
case shall be payable for the actual number of days 

  

 -25- 

 
elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the
Administrative Agent, and such determination shall be conclusive absent manifest error. 
 Section 2.12 Alternate Rate of Interest. If
prior to the commencement of any Interest Period for a Eurodollar Tranche: 
 (a) the Administrative Agent determines (which determination
shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or 
 (b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period
will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining the portion of their Loans (or its Loan) included in such Tranche for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the
Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Tranche to, or continuation of any Tranche as, a
Eurodollar Tranche shall be ineffective and (ii) if the Borrowing Request requests a Eurodollar Tranche, such Tranche shall be made as an ABR Tranche. 
 Section 2.13 Increased Costs. (a) If any Change in Law shall: 
 (i) impose, modify or deem
applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or 
 (ii) impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Tranches comprising the Loan made by
such Lender; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any portion of its Loan
comprising a Eurodollar Tranche (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or to reduce the amount of any sum received or receivable by such Lender hereunder (whether of principal, interest or
otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 
 (b) If any Lender determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such
Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence of this Agreement or the Loan made by such Lender to a level below that which such Lender or such Lender’s holding company could have
achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital 

  

 -26- 

 
adequacy), then from time to time the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender or such Lender’s
holding company for any such reduction suffered. 
 (c) A certificate of a Lender setting forth the amount or amounts necessary to compensate
such Lender or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount
shown as due on any such certificate within 10 days after receipt thereof. 
 (d) Failure or delay on the part of any Lender to demand
compensation pursuant to this Section shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender pursuant to this Section for any increased
costs or reductions incurred more than 270 days prior to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor;
provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof. 

Section 2.14 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Tranche other than on the last day
of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Tranche other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert,
continue or prepay any Eurodollar Tranche on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Tranche other than on the last day of the Interest Period applicable thereto as a result of a
request by the Borrower pursuant to Section 2.17, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Tranche, such loss, cost or expense to
any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of its Loan had such event not occurred, at the Adjusted LIBO
Rate that would have been applicable to such Tranche, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would
have been the Interest Period for such Tranche), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period,
for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to
the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 
 Section 2.15 Taxes. (a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and
without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified 

  

 -27- 

 
Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section) the Administrative Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. 
 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
 (c) The Borrower shall indemnify the Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any
Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed
or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally
imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be
conclusive absent manifest error. 
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a
Governmental Authority, the Borrower 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) Any Foreign Lender that is entitled to an exemption from or
reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without
withholding or at a reduced rate. 
 Section 2.16 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) 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 2.13, Section 2.14 or Section 2.15, or otherwise) prior to 12:00 noon, New York City time, on the
date when due, in immediately available funds, without 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 at such offices as it may designate from time to time, except that payments pursuant to Section 2.13, Section 2.14, Section 2.15
and Section 10.03 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 

  

 -28- 

 
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 shall be made in dollars. 
 (b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees
then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and
(ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties. 
 (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on
its Loan resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loan 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 the 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 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 its Loan to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this
paragraph 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 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 the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders 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. 
  

 -29- 

 (e) If any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.04(b) or Section 2.16(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. 
 Section 2.17
Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.13, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of
any Lender pursuant to Section 2.15, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loan hereunder or to assign its rights and obligations hereunder to another of its offices,
branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.13 or Section 2.15, as the case may be, in the future and (ii) would
not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation
or assignment. 
 (b) If any Lender requests compensation under Section 2.13, or if the Borrower is required to pay any additional
amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.15, or if any Lender defaults in its obligation to fund its Loan hereunder, then the Borrower may, at its sole expense and effort, upon
notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.04), all its interests, rights and obligations under
this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the
Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loan, accrued interest thereon, accrued fees and all other amounts
payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for
compensation under Section 2.13 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and
delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

no Default would exist and (ii) such designation is deemed to be an Investment in an Unrestricted Subsidiary in an amount equal to the fair market value as of the date of such designation of the MLP’s direct and indirect ownership interest

of its Restricted Subsidiaries has paid aggregate net consideration of at least $100,000,000, then, for the two Rolling Periods the last day of which immediately follow the date on which such acquisition is consummated, the numerator of the maximum
Consolidated Debt Coverage Ratio otherwise permitted above shall be increased by 0.5; thereafter, compliance shall be determined by reverting back to the Standard Ratio.

 ARTICLE VIII

 MLP Guarantee 
 Section
8.01 MLP Guarantee. 
 (a) The MLP, to the maximum extent permitted by applicable law, (i) absolutely, unconditionally and
irrevocably, guarantees to the Administrative Agent for the ratable benefit of the Guaranteed Creditors and their respective successors, endorsees, transferees 

  

 -48- 

 
and assigns, the prompt and complete payment and performance by the Borrower when due (whether at the stated maturity, by acceleration or otherwise) of the
Borrower Obligations and (ii) indemnifies and holds harmless each Guaranteed Creditor from, and agrees to pay to such Guaranteed Creditor, all reasonable costs and expenses (including reasonable counsel fees and expenses) incurred by such
Guaranteed Creditor in enforcing any of its rights under the guarantee contained in this Section 8.01. The MLP agrees that notwithstanding any stay, injunction or other prohibition preventing the payment by the Borrower of all or any portion of
the Borrower Obligations and notwithstanding that all or any portion of the Borrower Obligations may be unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Borrower, to the maximum
extent permitted by applicable law, such Borrower Obligations shall nevertheless be due and payable by the MLP for the purposes of this guarantee at the time such Borrower Obligations would by payable by the Borrower under the provisions of this
Agreement. Notwithstanding the foregoing, any enforcement of this guarantee with respect to the rights of any Guaranteed Creditor shall be accomplished by the Administrative Agent acting on behalf of such Guaranteed Creditor. The guarantee contained
in this Section 8.01 is a guarantee of payment and not collection, and the liability of the MLP is primary and not secondary. Anything to the contrary notwithstanding, the maximum liability of the MLP under the guarantee provided for in this
Article VIII shall in no event exceed the amount which can be guaranteed by the MLP under applicable federal and state laws relating to insolvency of debtors (after giving effect to any right of contribution provided for herein or in any other Loan
Document). 
 (b) The MLP agrees that if the maturity of the Borrower Obligations is accelerated by bankruptcy or otherwise, such maturity
shall also be deemed accelerated for the purpose of this guarantee without demand or notice to the MLP. The guarantee contained in this Section 8.01 is a continuing guarantee and shall remain in full force and effect until all the Borrower
Obligations and the obligations of the MLP under the guarantee contained in this Section 8.01 shall have been satisfied by payment in full in cash, notwithstanding that from time to time during the term of this Agreement the Borrower may be
free from any Borrower Obligations. 
 (c) No payment made by the Borrower, the MLP, any other guarantor or any other Person or received or
collected by any Guaranteed Creditor from the Borrower, the MLP, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to time in reduction of or in
payment of the Borrower Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of the MLP hereunder which shall, notwithstanding any such payment (other than any payment made by the Borrower or MLP in respect of the
Borrower Obligations or any payment received or collected from the Borrower or MLP in respect of the Borrower Obligations), remain liable for the Borrower Obligations until, subject to Section 8.05, the Borrower Obligations are paid in full in
cash. 
 Section 8.02 Subrogation. The MLP shall be subrogated to all the rights of any Guaranteed Creditor against the Borrower in
respect of any amounts paid by the MLP pursuant to the provisions of the guarantee contained in Section 8.01; provided, however, that the MLP shall not be entitled to enforce or to receive any payments arising out of, or based
upon, such 

  

 -49- 

 
right of subrogation with respect to any of the Borrower Obligations, nor shall the MLP seek or be entitled to seek any contribution or reimbursement from
the Borrower or any other Guarantor (or any other guarantor) in respect of payments made by the MLP hereunder, until all of the Borrower Obligations and the Guarantees thereof shall have been indefeasibly paid in full in cash or discharged. A
director, officer, employee or stockholder, as such, of the MLP shall not have any liability for any obligations of the MLP under the guarantee contained in Section 8.01 or any claim based on, in respect of or by reason of such obligations or
their creation. 
 Section 8.03 Amendments, etc. with respect to the Borrower Obligations. The MLP shall remain obligated hereunder
notwithstanding that, without any reservation of rights against the MLP and without notice to or further assent by the MLP, any demand for payment of any of the Borrower Obligations made by any Guaranteed Creditor may be rescinded by such Guaranteed
Creditor and any of the Borrower Obligations continued, and the Borrower Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect thereto, may,
from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by any Guaranteed Creditor, and any Loan Document and any other document executed and delivered in connection
therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders or all Lenders, as the case may be) may deem advisable from time to time, and any collateral security,
guarantee or right of offset at any time held by any Guaranteed Creditor for the payment of the Borrower Obligations may be sold, exchanged, waived, surrendered or released. Except as required by applicable law, no Guaranteed Creditor shall have any
obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Borrower Obligations or for the guarantee contained in Section 8.01 or any property subject thereto. 
 Section 8.04 Guarantee Absolute and Unconditional. To the fullest extent permitted by applicable law, the MLP hereby (a) waives diligence,
presentment, demand of payment, notice of intent to accelerate, notice of acceleration, notice of acceptance, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Borrower or the MLP, and all demands and notices
whatsoever, (b) acknowledges that any agreement, instrument or document evidencing the MLP Obligations may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document
evidencing the MLP Obligations without notice to them and (c) covenants that the MLP Obligations will not be discharged except by complete performance thereof. The MLP further agrees that to the fullest extent permitted by applicable law, if at
any time all or any part of any payment theretofore applied by any Person to any of the MLP Obligations is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of
the MLP, such MLP Obligations shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the MLP Obligations shall continue to be effective or be
reinstated, as the case may be, as though such application had not been made. 
 To the fullest extent permitted by applicable law, the
obligations of the MLP under this guarantee shall be as aforesaid full, irrevocable, unconditional and absolute and shall not be impaired, modified, discharged, released or limited by any occurrence or condition whatsoever, 

  

 -50- 

 
including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any
of the obligations and liabilities of the Borrower or the MLP contained in any of the Borrower Obligations or this Agreement, (ii) any impairment, modification, release or limitation of the liability of the Borrower, the MLP or any of their
estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable bankruptcy law, as amended, or other statute or from the decision of any court, (iii) the
assertion or exercise by the Borrower or the MLP of any rights or remedies under any of the Borrower Obligations or this Agreement or their delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the
purported assignment of any property as security for any of the Borrower Obligations, including all or any part of the rights of the Borrower or the MLP under this Agreement, (v) the extension of the time for payment by the Borrower or the MLP
of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of any of the Borrower Obligations or this Agreement or of the time for performance by the Borrower or the MLP of any other obligations under or
arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Borrower or the MLP set forth in this
Agreement, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit
of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, the Borrower or any of the MLP or any of their respective assets, or the disaffirmance of any of the Borrower Obligations, or this
Agreement in any such proceeding, (viii) the release or discharge of the Borrower or the MLP from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law,
(ix) the unenforceability of any of the Borrower Obligations or this Agreement, (x) any change in the name, business, capital structure, corporate existence, or ownership of the Borrower or the MLP or any other person or entity liable on
the obligations guaranteed hereby, (xi) the existence of any collateral or other guaranty, or any exchange, release or non-perfection of any collateral or other guaranty, or (xii) any other circumstance which might otherwise constitute a
defense available to, or a legal or equitable discharge of, a surety or the MLP. 
 Section 8.05 Reinstatement. To the maximum extent
permitted by applicable law, the guarantee contained in Section 8.01 shall continue to be effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Borrower Obligations is rescinded or must
otherwise be restored or returned by any Guaranteed Creditor upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or the MLP, or upon or as a result of the appointment of a receiver, intervenor or conservator
of, or trustee or similar officer for, the Borrower or the MLP or any substantial part of its property, or otherwise, all as though such payments had not been made. 
 Section 8.06 Payments. The MLP hereby guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim and without deduction for any taxes and in immediately available
funds and in dollars at the Administrative Agent’s payment office at the address provided in Section 10.01 of this Agreement.

herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as
Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the
Lenders as shall be necessary under the circumstances as provided in Section 10.02) or in the absence of its own gross negligence or wilful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and
until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not 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, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other
terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, 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 the Administrative Agent. 
 The
Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed
or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative
Agent may consult with legal counsel (who may be counsel for the 

  

 -52- 

 
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. 
 The Administrative Agent may perform any and all its duties and exercise its rights
and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related
Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the
syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 
 Subject to the appointment and
acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in
consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its
resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent which shall be a Lender and a commercial bank with an office in New York, New York and having a combined capital and surplus
of at least $500,000,000, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. 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 Administrative Agent’s resignation hereunder, the provisions of this Article and Section 10.03 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 it was acting as Administrative Agent. 
 Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender 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 the Administrative Agent or any other Lender
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 related agreement or any document furnished
hereunder or thereunder. 
 None of the Syndication Agent, the Co-Documentation Agents or the Co-Managing Agents shall have any duties,
responsibilities or liabilities under this Agreement or the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

 (b) Notices and other

unless otherwise agreed by the Administrative Agent and the applicable Lender. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to
procedures approved by it; provided that approval of such procedures may be limited to particular notices or communications. 
 (c)
Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto. All notices and other communications given to any party hereto in accordance with the provisions of this
Agreement shall be deemed to have been given on the date of receipt. 
 Section 10.02 Waivers; Amendments. (a) No failure or
delay by the Administrative Agent or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to
enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent and the Lenders hereunder are cumulative and are not exclusive of any
rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this
Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a 

  

 -54- 

 
waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time. 

(b) Neither this Agreement nor the Subsidiary Guaranty nor any provision hereof or thereof may be waived, amended or modified (except as expressly set
forth herein or therein) except pursuant to an agreement or agreements in writing entered into by the Borrower, the MLP and the Required Lenders or by the Borrower, the MLP and the Administrative Agent with the consent of the Required Lenders;
provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees
payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan, or any interest thereon, or any fees payable hereunder, or reduce the amount of,
waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.16(b) or (c) in a manner that would alter the pro
rata sharing of payments required thereby, without the written consent of each Lender, (v) waive or amend Section 2.09, Section 4.01, Article VIII or release the MLP from its obligations hereunder or release any other Guarantor from a
Subsidiary Guaranty (except as expressly set forth in the Subsidiary Guaranty) without the written consent of each Lender or (vi) change any of the provisions of this Section or the definition of “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 written consent of each Lender; provided
further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent hereunder without the prior written consent of the Administrative Agent. 
 Section 10.03 Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the
Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and
administration of this Agreement or any amendments, modifications or waivers of the provisions hereof (whether or not the transactions contemplated hereby or thereby shall be consummated), and (ii) all out-of-pocket expenses incurred by the
Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement, including
its rights under this Section, or in connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans. 
 (b) The Borrower shall indemnify the Administrative Agent and each Lender, and each Related Party of any of the foregoing Persons (each such Person being
called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the
performance by 

  

 -55- 

 
the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby,
(ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability
related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless
of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee. 
 (c)
To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section (and without limiting the Borrower’s obligation to do so), each Lender severally
agrees to pay to the Administrative Agent such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed
expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such. 
 (d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions,
any Loan or the use of the proceeds thereof. 
 (e) All amounts due under this Section shall be payable not later than 5 Business Days after
written demand therefor. 
 Section 10.04 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) and, to the extent expressly contemplated hereby, the Related
Parties of each of the Administrative Agent and the Lenders) 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 

  

 -56- 

 
this Agreement (including all or a portion of its Loan) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

 (A) the Borrower; provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a
Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee; and 
 (B) the Administrative Agent;
provided that no consent of the Administrative Agent shall be required for an assignment of any Loan (or portion thereof) to an assignee that is a Lender immediately prior to giving effect to such assignment. 
 (ii) Assignments shall be subject to the following additional conditions: 
 (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Loan, the amount of the Loan of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative
Agent otherwise consent; provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; 
 (B) 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; 
 (C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and
recordation fee of $3,500; and 
 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative
Questionnaire. 
 For the purposes of this Section 10.04(b), the term “Approved Fund” has the following meaning: 

“Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank
loans and similar extensions of credit in the ordinary course of its business and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages
a Lender. 
 (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) of this Section, from and after the effective
date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the
assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement 

  

 -57- 

 
(and, in the case of an Assignment and Assumption 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 2.13, Section 2.14, Section 2.15 and 10.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not
comply with this Section 10.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section. 
 (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
Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the principal amount of the Loan owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The
entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may 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) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed
Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of
this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any
payment required to be made by it pursuant to Section 2.04(b), Section 2.16(d) or 10.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register
unless and until such payment shall have been made in full, together with all accrued interest thereon. 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 (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Loan); 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 and (C) the Borrower, the Administrative Agent 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 pursuant to which a Lender sells such a participation shall provide that such Lender shall
retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that 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 the first proviso to Section 10.02(b) that affects such Participant. Subject to 

  

 -58- 

 
paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.13, Section 2.14 and
Section 2.15 to the same extent as if it were a Lender 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 10.08 as though it were a Lender; provided such Participant agrees to be subject to Section 2.16(c) as though it were a Lender. 
 (ii) A Participant shall not be entitled to receive any greater payment under Section 2.13 or Section 2.15 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. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of
Section 2.15 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.15(e) as though it were a Lender. 
 (d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of
such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, 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. 
 Section 10.05 Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of the Loans, regardless of
any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is
extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid. The provisions of
Section 2.13, Section 2.14, Section 2.15 and 10.03 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans or the termination
of this Agreement or any provision hereof. 
 Section 10.06 Counterparts; Integration; Effectiveness. This Agreement may be executed
in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with
respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject
matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the 

  

 -59- 

 
Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other required parties hereto,
and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of
a manually executed counterpart of this Agreement. 
 Section 10.07 Severability. Any provision of this Agreement held to be invalid,
illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions
hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. 
 Section 10.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates 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 obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or the MLP
against any of and all the obligations of the Borrower or the MLP now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such
obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have. 
 Section 10.09 Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and
governed by the law of the State of New York. 
 (b) The Borrower and the MLP each hereby irrevocably and unconditionally submits, for itself
and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in
any action or proceeding arising out of or relating to this Agreement, 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. 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 shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this
Agreement against the Borrower or its properties in the courts of any jurisdiction. 
 (c) The Borrower and the MLP each 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 in any
court referred to in paragraph (b) of this Section. Each of the parties 

  

 -60- 

 
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. 
 (d) Each party to this Agreement irrevocably consents to service of process in the manner provided for
notices in Section 10.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. 
 Section 10.10 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 ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (a) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (b) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 Section 10.11 Headings. Article and Section headings and
the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement. 
 Section 10.12 Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as
defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable
laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the
enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its
rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower or
(h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other
than the Borrower. For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent or
any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as
confidential. Any Person required to maintain the 

  

 -61- 

 
confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. 
 Section 10.13 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such
Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in
accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would
have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above
the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender. 
 Section 10.14 Limitation of Liability. Neither the General Partner nor the general partner(s) of the MLP shall be liable for (a) the
obligations of the Borrower under this Agreement or (b) the obligations of the MLP under this Agreement, including in each case, without limitation, by reason of any payment obligation imposed by governing state partnership statutes and any
provision of the applicable limited partnership agreement of the Borrower or the MLP that requires such General Partner or general partner(s), as the case may be, to restore a capital account deficit. 
 Section 10.15 USA PATRIOT Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into
law October 26, 2001)) (the “Act”) hereby notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name
and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

 EXHIBIT C 
 OPINION OF COUNSEL FOR THE BORROWER AND THE MLP 
 February 1, 2008 
 To the Lenders and the Administrative 
     Agent
Referred to Below 
 c/o JPMorgan Chase Bank, N.A., as 
     Administrative Agent 
 270 Park Avenue 
 New York, New York 10017 
 Dear Sirs: 
 [I/We] have acted as counsel for NuStar Logistics, L.P. (the “Borrower”) and NuStar Energy L.P. (the “MLP” and each of the Subsidiaries of the MLP listed on Annex I hereto (the “Subsidiary
Guarantors” and, together with the Borrower, the “Loan Parties”), in connection with the Term Loan Credit Agreement dated as of February 1, 2008 (the “Credit Agreement”), among the Borrower, the MLP,
the banks and other financial institutions identified therein as Lenders, JPMorgan Chase Bank, N.A., as Administrative Agent, and others as agents, and the other Loan Documents identified below. This opinion is being furnished to you pursuant to
Section 4.01(b) of the Credit Agreement. Unless otherwise defined herein, terms defined in the Credit Agreement and used herein shall have the meanings given to them in the Credit Agreement. 
 In that connection, we have examined executed copies of the Credit Agreement, the Subsidiary Guaranty Agreement dated as of even date herewith made by
each of the Guarantors (as defined therein) in favor of the Administrative Agent (the “Subsidiary Guaranty”), and the notes executed and delivered on the date hereof pursuant to Section 2.07(e) of the Credit Agreement (the
“Loan Documents”). 
 In addition, [I, or individuals under my direction,/We] have examined originals or copies, certified
or otherwise identified to [my/our] satisfaction, of such documents, corporate records, certificates of public officials and other instruments and have conducted such other investigations of fact and law as [I/we] have deemed necessary or advisable
for purposes of this opinion. 
 Upon the basis of the foregoing, [I am/we are] of the opinion that: 
 1. The Loan Documents constitute the legal, valid and binding obligations of the Loan Parties party thereto, enforceable against such Loan Parties under
the law of the State of New York in accordance with their respective terms. 
 2. In a case properly argued and presented, a Texas court or a
Federal court sitting in Texas and applying Texas conflict of law principles, as set out in Section 35.51 of the Texas Business and Commerce Code, would give effect to the provisions of the Credit Agreement and 

  

 Exhibit C - 1 

 
the Subsidiary Guaranty selecting New York law as governing, and would apply the substantive laws of the State of New York in construing the Credit Agreement
and the Subsidiary Guaranty. 
 3. Under the circumstances contemplated by the Credit Agreement, the making of the Loans will not violate
Section 7 of the Securities Exchange Act of 1934, as amended, or any regulation issued pursuant thereto, including without limitation, the provisions of Regulation T, U or X of the Board of Governors of the Federal Reserve System. 

4. No Loan Party is an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 
 5. The Borrower (a) is a limited partnership duly formed and validly existing under the laws of the State of Delaware and (b) has the limited
partnership power and authority to (i) own property and conduct the business in which it is currently engaged and in which it proposes, as of the date hereof, to be engaged after the date hereof, (ii) make, deliver and perform the Loan
Documents to which it is a party in accordance with the terms and provisions thereof and (iii) borrow under the Credit Agreement. 
 6.
The MLP (a) is a limited partnership duly formed and validly existing under the laws of the State of Delaware and (b) has the limited partnership power and authority to (i) own property and conduct the business in which it is
currently engaged and in which it proposes, as of the date hereof, to be engaged after the date hereof, and (ii) make, deliver and perform the Credit Agreement in accordance with the terms and provisions thereof. 
 7. Each Subsidiary Guarantor (a) is a limited partnership, corporation or limited liability company validly existing under the laws of the
jurisdiction of its formation as described on Annex I hereto and (b) has the limited partnership, corporate or limited liability company power and authority to make, deliver and perform the Subsidiary Guaranty in accordance with the terms and
provisions thereof. 
 8. The execution, delivery and performance of the Credit Agreement by the Borrower and the MLP, and of the Subsidiary
Guaranty by each Subsidiary Guarantor, and the borrowing of the Loans by the Borrower under the Credit Agreement, have been duly authorized by all necessary actions on behalf of the Loan Parties and each other Person whose authorization is relevant
to, or constitutes, authorization on behalf of either Loan Party. 
 9. The Loan Documents have been duly executed and delivered on behalf of
the Loan Parties, as applicable. 
 10. No approvals or consents of any governmental authority of the State of Texas or the United States of
America or other consents or approvals by any other Person which have not been obtained on or prior to the date hereof are required (a) in connection with the participation by the Loan Parties in connection with the transactions under the Loan
Documents or the execution, delivery and performance by any Loan Party of the Loan Documents to which it is a party, or (b) for the validity and enforceability of the Loan Documents and the exercise by the Lenders of their rights and remedies
thereunder. 
  

 Exhibit C - 2 

 11. The execution, delivery and performance by the Loan Parties of the Loan Documents will not
(a) violate any provision of the Partnership Agreement (Borrower), the Partnership Agreement (MLP), or the certificate of incorporation, bylaws, partnership agreement or limited liability company agreement, as applicable, of any Subsidiary
Guarantor, (b) result in the breach of, or constitute a default under, any indenture or loan or credit agreement or any other material agreement, lease or instrument, known to me after due inquiry, to which any of the Loan Parties is a party or
by which its properties may be bound, (c) result in, or require, the creation or imposition of any Lien on any of its properties or revenues pursuant to any requirement of law, rule regulation or order of any governmental authority of the State
of Texas or the United States of America or material contractual obligation binding upon any Loan Party, or (d) result in any violation by any Loan Party of any applicable law of the State of Texas or the United States of America. 

12. The Borrower is not subject to regulation under any statute or regulation of the State of Texas or the United States of America that limits its
ability to incur indebtedness. 
 13. To my knowledge (having made due inquiry with respect thereto), except as disclosed in the Credit
Agreement, no litigation, investigation or proceeding of or before any arbitrator or governmental authority is pending or threatened by or against any Loan Party or against any of the properties or revenues of either (a) with respect to the
Loan Documents or any of the transactions contemplated thereby or (b) which, if adversely determined, could reasonably be expected to have a Material Adverse Effect.

other document made, delivered or given in connection therewith, in each case whether on account of principal, interest, reimbursement obligations, fees, indemnities, costs, expenses or otherwise (including, without limitation, all fees and

 “Guarantor Obligations”: means with respect to any Guarantor, the collective reference to (i) the Borrower Obligations and
(ii) all obligations and liabilities of such Guarantor which may arise under or in connection with this Agreement, in each case whether on account of guarantee obligations, reimbursement obligations, loan obligations, fees, indemnities, costs,

 SECTION 2. GUARANTEE

stated maturity, by acceleration or otherwise) of the Borrower Obligations and (ii) indemnifies and holds harmless the Administrative Agent and each Lender from, and agrees to pay to the Administrative Agent and each Lender, all reasonable
costs and expenses (including reasonable counsel fees and expenses) incurred by the Administrative Agent or such Lender in enforcing any of its rights under this Agreement. The guarantee in this Section 2.1 is a continuing guarantee, and shall
apply to all Obligations owing at any time whenever arising or incurred and shall remain in full force and effect until the Obligations have been indefeasibly paid in full in cash. Each Guarantor agrees that notwithstanding any stay, injunction or
other prohibition preventing the payment by the Borrower of all or any portion of the Borrower Obligations and notwithstanding that all or any portion of the Borrower Obligations may be unenforceable or not allowable due to the existence of a
bankruptcy, reorganization or similar proceeding involving the Borrower, such Borrower Obligations shall nevertheless be due and payable by such Guarantor for the purposes of this Agreement at the time such Borrower Obligations would by payable by
the Borrower under the provisions of the Credit Agreement. Notwithstanding the foregoing, any enforcement of this Agreement with respect to the rights of any Lender may be accomplished by the Administrative Agent acting on behalf of such Lender.

 (b) Anything herein or in any other Loan Document to the contrary notwithstanding, the maximum liability of each Guarantor hereunder shall
in no event exceed the amount which can be guaranteed by such Guarantor under applicable federal and state laws relating to the insolvency of debtors (after giving effect to the right of contribution established in Section 2.2). 
  

 Exhibit D - 4 

 (c) Each Guarantor agrees that the Borrower Obligations may at any time and from time to time exceed the
amount of the liability of such Guarantor hereunder without impairing the guarantee contained in this Section 2 or affecting the rights and remedies of the Administrative Agent or any Lender hereunder. 
 (d) The guarantee contained in this Section 2.1 shall remain in full force and effect until all the Borrower Obligations and the obligations of each
Guarantor under the guarantee contained in this Section 2.1 shall have been satisfied by indefeasible payment in full in cash, notwithstanding that from time to time during the term of the Credit Agreement the Borrower may be free from any
Borrower Obligations. 
 (e) No payment made by the Borrower, any of the Guarantors, any other guarantor or any other Person or received or
collected by the Administrative Agent or any Lender from the Borrower, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any set-off or appropriation or application at any time or from time to
time in reduction of or in payment of the Borrower Obligations shall be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding any such payment (other than any payment made by such
Guarantor in respect of the Borrower Obligations or any payment received or collected from such Guarantor in respect of the Borrower Obligations), remain liable for the Borrower Obligations up to the maximum liability of such Guarantor hereunder
until, subject to Section 2.6, the Borrower Obligations are indefeasibly paid in full in cash. 
 2.2 Right of Contribution. Each
Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution from and against any other Guarantor
hereunder which has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and conditions of Section 2.3. The provisions of this Section 2.2 shall in no respect limit the
obligations and liabilities of any Guarantor to the Administrative Agent and the Lenders, and each Guarantor shall remain liable to the Administrative Agent and the Lenders for the full amount guaranteed by such Guarantor hereunder. 
 2.3 No Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor by the
Administrative Agent or any Lender, no Guarantor shall be entitled to be subrogated to any of the rights of the Administrative Agent or any Lender against the Borrower or any other Guarantor (or any other guarantor) or any collateral security or
guarantee or right of offset held by the Administrative Agent or any Lender for the payment of the Borrower Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Borrower or any other Guarantor
(or any other guarantor) in respect of payments made by such Guarantor hereunder, until all amounts owing to the Administrative Agent and the Lenders by the Borrower on account of the Borrower Obligations are indefeasibly paid in full in cash. If
any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Borrower Obligations shall not have been paid in full in cash, such amount shall be held by such Guarantor in trust for the Administrative
Agent and the Lenders, segregated from other funds of such 

  

 Exhibit D - 5 

 
Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the exact form received by such Guarantor (duly
indorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Borrower Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine. 
 2.4 Amendments, etc. with respect to the Borrower Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the Borrower Obligations made by the Administrative Agent or any Lender may be rescinded by the Administrative
Agent or such Lender and any of the Borrower Obligations continued, and the Borrower Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor or right of offset with respect
thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Administrative Agent or any Lender, and the Credit Agreement and the other Loan Documents
and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as the Administrative Agent (or the Required Lenders or all Lenders, as the case may be) may deem
advisable from time to time, and any collateral security, guarantee or right of offset at any time held by the Administrative Agent or any Lender for the payment of the Borrower Obligations may be sold, exchanged, waived, surrendered or released.
Neither the Administrative Agent nor any Lender shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Borrower Obligations or for the guarantee contained in this Section 2 or any
property subject thereto. 
 2.5 Guarantee Absolute and Unconditional. Each Guarantor waives any and all notice of the creation,
renewal, extension or accrual of any of the Borrower Obligations and notice of or proof of reliance by the Administrative Agent or any Lender upon the guarantee contained in this Section 2 or acceptance of the guarantee contained in this
Section 2; the Borrower Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and all
dealings between the Borrower and any of the Guarantors, on the one hand, and the Administrative Agent and the Lenders, on the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance upon the guarantee
contained in this Section 2. Each Guarantor waives diligence, presentment, protest, demand for payment, notice of intent to accelerate, notice of acceleration and notice of default or nonpayment to or upon the Borrower or any of the Guarantors
with respect to the Borrower Obligations. Each Guarantor understands and agrees that the guarantee contained in this Section 2 shall be construed as a continuing, absolute and unconditional guarantee of payment without regard to (a) the
validity or enforceability of the Credit Agreement or any other Loan Document, any of the Borrower Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time or from time to time held by
the Administrative Agent or any Lender, (b) any defense, set-off or counterclaim (other than a defense of payment or performance) which may at any time be available to or be asserted by the Borrower or any other Person against the
Administrative Agent or any Lender, (c) any extension, other indulgence, renewal, settlement, discharge, compromise, waiver, subordination or release in respect of any 

  

 Exhibit D - 6 

 
Borrower Obligation, security, Person or otherwise, (d) any modification or amendment of or supplement to the Borrower Obligations, including any
increase or decrease in the principal, the rates of interest or other amounts payable thereunder, (e) any release, non-perfection or invalidity of any direct or indirect security for any Borrower Obligation, (f) any change in the
existence, structure, constitution, name, objects, powers, business, control or ownership of the Borrower or any other Person, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Borrower or any other Person or
its assets, (g) any limitation, postponement, prohibition, subordination or other restriction on the rights of the Administrative Agent or the Lenders to payment of the Borrower Obligations, (h) any release, substitution or addition of any
cosigner, endorser or other guarantor of the Borrower Obligations, (i) any defense arising by reason of any failure of the Borrower to make any presentment, demand for performance, notice of non-performance, protest, notice of intent to
accelerate, notice of acceleration and any other notice, including notice of all of the following: acceptance of this Agreement, partial payment or non-payment of all or any part of the Borrower Obligations and the existence, creation, or incurring
of new or additional Borrower Obligations, (j) any defense arising by reason of any failure of the Administrative Agent to proceed against the Borrower or any other Person, to proceed against, apply or exhaust any security held from the
Borrower or any other Person for the Borrower Obligations, to proceed against, apply or exhaust any security held from any Guarantor or any other Person for this Agreement or to pursue any other remedy in the power of the Administrative Agent or the
Lenders whatsoever, (k) any law which provides that the obligation of a guarantor must neither be larger in amount nor in other respects more burdensome than that of the principal obligation or which reduces a guarantor’s obligation in
proportion to the principal obligation, (l) any defense arising by reason of any incapacity, lack of authority, or other defense of the Borrower or any other Person, or by reason of any limitation, postponement, prohibition on the
Administrative Agent’s or the Lenders’ right to payment of the Borrower Obligations or any part thereof, or by reason of the cessation from any cause whatsoever of the liability of the Borrower or any other Person with respect to all or
any part of the Borrower Obligations, or by reason of any act or omission of the Administrative Agent or the Lenders which directly or indirectly results in the discharge or release of the Borrower or any other Person of all or any part of the
Borrower Obligations or any security or guarantee therefore, whether by contract, operation of law or otherwise, (m) any defense arising by failure by the Administrative Agent or the Lenders to obtain, perfect or maintain a perfected or prior
(or any) security interest in or lien or encumbrance upon any property of the Borrower or any other Person, or by reason of any interest of the Borrower in any property, whether as owner thereof or the holder of a security interest therein or lien
or encumbrance thereon, being invalidated, voided, declared fraudulent or preferential or otherwise set aside, or by reason of any impairment by the Borrower of any right to recourse or collateral, (n) any defense arising by reason of the
failure of the Borrower to marshal any assets, (o) any defense based upon any failure of the Administrative Agent or any Lender to give to the Borrower or any Guarantor notice of any sale or other disposition of any property securing any or all
of the Obligations, or any defect in any notice that may be given in connection with any sale or other disposition of any such property, or any failure of the Administrative Agent or any Lender to comply with any provision of applicable law in
enforcing any security interest in or lien upon any such property, including any failure of the Administrative Agent or any Lender to dispose of any such property in a commercially reasonable manner, (p) any dealing whatsoever with the Borrower
or other Person 
  

 Exhibit D - 7 

 
or any security, whether negligently or not, or any failure to do so, (q) any defense based upon or arising out any bankruptcy, insolvency,
reorganization, moratorium, arrangement, readjustment of debt, liquidation or dissolution proceeding commenced by or against the Borrower or any other Person, including any discharge of, or bar against collecting, any of the Borrower Obligations, in
or as a result of any such proceeding, (r) or any other act or omission to act or delay of any kind by the Borrower, the Administrative Agent, any Lender, any Guarantor or any other Person or any other circumstance whatsoever, whether similar
or dissimilar to the foregoing, which might, but for the provisions of this Section 2.5, constitute a legal or equitable discharge, limitation or reduction of such Guarantor’s obligations hereunder (other than the indefeasible payment in
full in cash of all of the Borrower Obligations). The foregoing provisions apply (and the foregoing waivers will be effective) even if the effect of any action (or failure to take any action) by the Administrative Agent or any Lender is to destroy
or diminish a Guarantor’s subrogation rights, such Guarantor’s right to proceed against the Borrower for reimbursement, such Guarantor’s right to recover contribution from any other Guarantor or any other right or remedy. When making
any demand hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, the Administrative Agent or any Lender may, but shall be under no obligation to, make a similar demand on or otherwise pursue such rights and
remedies as it may have against the Borrower, any other Guarantor or any other Person or against any collateral security or guarantee for the Borrower Obligations or any right of offset with respect thereto, and any failure by the Administrative
Agent or any Lender to make any such demand, to pursue such other rights or remedies or to collect any payments from the Borrower, any other Guarantor or any other Person or to realize upon any such collateral security or guarantee or to exercise
any such right of offset, or any release of the Borrower, any other Guarantor or any other Person or any such collateral security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder, and shall not
impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Administrative Agent or any Lender against any Guarantor. For the purposes hereof “demand” shall include the commencement and
continuance of any legal proceedings. 
 2.6 Reinstatement. The guarantee contained in this Section 2 shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any part thereof, of any of the Borrower Obligations is rescinded or must otherwise be restored or returned by the Administrative Agent or any Lender upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Borrower or any Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or any Guarantor or any
substantial part of its property, or otherwise, all as though such payments had not been made. 
 2.7 Payments. Each Guarantor hereby
guarantees that payments hereunder will be paid to the Administrative Agent without set-off or counterclaim and without deduction for any taxes and in immediately available funds and in dollars at the Administrative Agent’s payment office at
the address provided in Section 2.16 of the Credit Agreement. 
  

 Exhibit D - 8 

 SECTION 3. REPRESENTATIONS AND WARRANTIES 
 To induce the Administrative Agent and the Lenders to enter into the Credit Agreement and to induce the Lenders to make their respective term loans to
the Borrower thereunder, each Guarantor hereby represents and warrants to the Administrative Agent and each Lender that: 
 3.1
Representations in Credit Agreement. In the case of each Guarantor, the representations and warranties relating to subsidiaries of the Borrower and the MLP set forth in Article 3 of the Credit Agreement, each of which is hereby incorporated
herein by reference and shall apply mutatis mutandis, are true and correct, and the Administrative Agent and each Lender shall be entitled to rely on each of them as if they were fully set forth herein. Each Guarantor also represents and warrants
that it is Solvent and that it is a Subsidiary of the MLP. 
 SECTION 4. COVENANTS 
 Each Guarantor covenants and agrees with the Administrative Agent and the Lenders that, from and after the date of this Agreement until the Obligations
shall have been indefeasibly paid in full in cash, in the case of each Guarantor, such Guarantor shall take, or shall refrain from taking, as the case may be, each action that is necessary to be taken or not taken, as the case may be, so that no
Default or Event of Default is caused by the failure to take such action or to refrain from taking such action by such Guarantor or any of its Subsidiaries. 
 SECTION 5. THE ADMINISTRATIVE AGENT 
 5.1 Authority of Administrative Agent. Each Guarantor
acknowledges that the rights and responsibilities of the Administrative Agent under this Agreement with respect to any action taken by the Administrative Agent or the exercise or non-exercise by the Administrative Agent of any option, voting right,
request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall, as between the Administrative Agent and the Lenders, be governed by the Credit Agreement and by such other agreements with respect
thereto as may exist from time to time among them, but, as between the Administrative Agent and the Guarantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the Lenders with full and valid authority so to act or
refrain from acting, and no Guarantor shall be under any obligation, or entitlement, to make any inquiry respecting such authority. 
 SECTION
6. MISCELLANEOUS 
 6.1 Amendments in Writing. None of the terms or provisions of this Agreement may be waived, amended, supplemented
or otherwise modified except in accordance with Section 10.02 of the Credit Agreement. 
 6.2 Notices. All notices, requests and
demands to or upon the Administrative Agent or any Guarantor hereunder shall be effected in the manner provided for in Section 10.01 of the Credit Agreement; provided that any such notice, request or demand to or upon any Guarantor shall be
addressed to such Guarantor at its notice address set forth on Schedule 1. 
  

 Exhibit D - 9 

 6.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither the Administrative Agent nor any
Lender shall by any act (except by a written instrument pursuant to Section 6.1), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Default or Event of Default. No
failure to exercise, nor any delay in exercising, on the part of the Administrative Agent or any Lender, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. A waiver by the Administrative Agent or any Lender of any right or remedy hereunder on any one occasion shall not be construed as
a bar to any right or remedy which the Administrative Agent or such Lender would otherwise have on any future occasion. The rights and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law. 
 6.4 Enforcement Expenses; Indemnification. 
 (a) Each Guarantor agrees to pay or reimburse each Lender and the Administrative Agent for all its costs and expenses incurred in collecting against such
Guarantor under the guarantee contained in Section 2 or otherwise enforcing or preserving any rights under this Agreement and which such Guarantor is a party, including, without limitation, the reasonable fees and disbursements of counsel
(including the allocated fees and expenses of in-house counsel) to each Lender and of counsel to the Administrative Agent. 
 (b) Each
Guarantor agrees to pay, and to save the Administrative Agent and the Lenders harmless from, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement to the same extent the Borrower would be required to do so pursuant to Section 10.03 of the Credit Agreement. 
 (c) The agreements in this Section 6.4 shall survive repayment of the Obligations and all other amounts payable under the Credit Agreement and the
other Loan Documents. 
 6.5 Successors and Assigns. This Agreement shall be binding upon the successors and assigns of each Guarantor
and shall inure to the benefit of the Administrative Agent and the Lenders and their successors and assigns; provided that no Guarantor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written
consent of the Administrative Agent. 
 6.6 Counterparts. This Agreement may be executed by one or more of the parties to this
Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be
lodged with the Borrower and the Administrative Agent. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or facsimile shall be effective as delivery of a manually executed counterpart of this Agreement.

  

 Exhibit D - 10 

 6.7 Severability. Any provision of this Agreement which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. 
 6.8 Integration. This Agreement and the other Loan
Documents represent the entire agreement of the Guarantors, the Administrative Agent and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Administrative
Agent or any Lender relative to subject matter hereof and thereof not expressly set forth or referred to herein. 
 6.9 GOVERNING LAW.
THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK AND TO THE EXTENT CONTROLLING, LAWS OF THE UNITED STATES OF
AMERICA. 
 6.10 Submission to Jurisdiction; Waivers. Each Guarantor hereby irrevocably and unconditionally: 
 (a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party,
or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the Courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate
courts from any thereof; 
 (b) consents that any such action or proceeding may be brought in such courts and waives any objection that it
may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same; 
 (c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any
substantially similar form of mail), postage prepaid, to such Guarantor at its address referred to in Section 6.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto; 
 (d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue
in any other jurisdiction; and 
 (e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any
legal action or proceeding referred to in this Section 6.10 any special, exemplary, punitive or consequential damages. 
 6.11
Acknowledgments. Each Guarantor hereby acknowledges that: 
  

 Exhibit D - 11 

 (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the
other Loan Documents to which it is a party; 
 (b) neither the Administrative Agent nor any Lender has any fiduciary relationship with or
duty to any Guarantor arising out of or in connection with this Agreement or the relationship between the Administrative Agent and Lenders, on one hand, and the Guarantors, on the other hand, in connection herewith or therewith is solely that of
debtor and creditor; and 
 (c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the
transactions contemplated hereby among the Lenders or among the Guarantors and the Lenders. 
 6.12 WAIVERS OF JURY TRIAL. EACH
GUARANTOR, AND THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN. 

6.13 Section Headings. The Section headings used in this Agreement are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof. 
 6.14 Additional Guarantors. Each Subsidiary of the MLP that is
required to become a party to this Agreement pursuant to Section 5.11 of the Credit Agreement shall become a party hereto and a Guarantor hereunder for all purposes of this Agreement upon execution and delivery by such Subsidiary of an
Assumption Agreement in the form of Annex I hereto. 
 6.15 Release of Guarantors. At the request and sole expense of the Borrower and
the MLP: any Subsidiary of the MLP that is a Guarantor shall be released from its obligations hereunder in the event that (a) all of the Equity Interests of such Guarantor shall be sold, transferred or otherwise disposed of in a transaction
permitted by the Credit Agreement or (b) such Subsidiary does not guarantee any obligations of the MLP or any of its Subsidiaries under any public debt instrument (including the Indentures), provided that the Borrower and the MLP shall have
delivered to the Administrative Agent, at least ten Business Days prior to the date of the proposed release, a written request of a Responsible Officer of each of the Borrower and the MLP for release identifying the relevant Guarantor and the terms
of the sale or other disposition or release from such guaranty, as the case may be, in reasonable detail, together with a certification by the Borrower and the MLP that such transaction is in compliance with the Credit Agreement and the other Loan
Documents and that at the time of such release, after giving effect to any other Subsidiary of the MLP becoming a party hereto, the Borrower and the MLP are in compliance with Section 5.11 of the Credit Agreement and no Event of Default exists
or would exist as a result of such release.

the MLP shall be liable for (c) the obligations of the Borrower under this Agreement or (d) the obligations of the MLP under this Agreement, including in each case, without limitation, by

reason of any payment obligation imposed by governing state partnership statutes and any provision of the applicable limited partnership agreement of the
