 SECTION 2. AMOUNT AND TERMS OF COMMITMENTS 
  
 2.1 The Commitments. 
  
 (a) The Revolving Credit Commitments. On the terms and subject to the conditions contained in this Agreement, each Lender severally agrees to make
loans in Dollars (each a “Revolving Loan”) to the Borrower from time to time on any Business Day during the period from the Closing Date until the Revolving Credit Termination Date in an aggregate principal amount at any time
outstanding for all such loans by such Lender not to exceed such Lender’s Revolving Credit Commitment; provided, however, that at no time shall any Lender be obligated to make a Revolving Loan in excess of such Lender’s
Ratable Portion of the Available Credit. Within the limits of the Revolving Credit Commitment of each Lender, amounts of Revolving Loans repaid may be reborrowed under this Section 2.1. 
  
 (b) Incremental Credit Extensions. (i) The
Borrower may from time to time after the Closing Date request one or more increases in the Revolving Credit Commitments (each, a “Revolving Credit Commitment Increase”); provided, however, that (A) the aggregate
amount of all Revolving Credit Commitment Increases shall not exceed $200,000,000 and (B) each Revolving Credit Commitment Increase shall be in an amount not less than $20,000,000. Nothing in this Agreement shall be construed to obligate the
Administrative Agent, any other Agent, any Arranger or any Lender to negotiate for (whether or not in good faith), solicit, provide or commit to provide any Revolving Credit Commitment Increase. The Administrative Agent shall promptly notify each
Lender of each proposed Revolving Credit Commitment Increase. Each such Lender (and each of their Affiliates and Approved Funds) may, in its sole discretion, commit to participate in such Revolving Credit Commitment Increase by forwarding its
commitment therefor to the Administrative Agent in form and substance satisfactory to the Administrative Agent. The Administrative Agent shall, after consultation with the Borrower, allocate, but in amounts not to exceed for each such Lender the
commitment received from such Lender, Affiliate or Approved Fund, the Revolving Credit Commitment Increase commitments to be made as part of such Revolving Credit Commitment Increase to the Lenders from which it has received such written
commitments. If the Administrative Agent does not receive enough commitments from existing Lenders or their Affiliates or Approved Funds, it may, after consultation with the Borrower, allocate to Eligible Assignees any excess of the proposed amount
of such Revolving Credit Commitment Increase agreed with the Borrower over the aggregate amounts of the commitments received from existing Lenders or their Affiliates or Approved Funds. Each Revolving Credit Commitment Increase shall become
effective on a date agreed by the Borrower and the Administrative Agent (each, an “Incremental Credit Extension Date”), which shall be in any case on or after the date of satisfaction of the conditions precedent set forth in
Section 4.4. The Administrative Agent shall notify the Lenders and the Borrower, on or before 
  

 20 

 1:00 p.m., New York City time, on the Business Day following an Incremental Credit Extension Date of the
effectiveness of a Revolving Credit Commitment Increase and shall record in the Register all applicable additional information in respect of such Revolving Credit Commitment Increase. 
  
 (ii) (A) The commitments under each Revolving Credit Commitment Increase shall be deemed for all purposes
part of the Revolving Credit Commitments, (B) each Lender or Eligible Assignee participating in such Revolving Credit Commitment Increase shall become a Lender with respect to the Revolving Credit Commitments and all matters relating thereto
and (C) the commitments under each Revolving Credit Commitment Increase shall have the same terms and conditions as the Revolving Credit Commitments. On the Incremental Credit Extension Date for any Revolving Credit Commitment Increase, each
Lender or Eligible Assignee participating in such Revolving Credit Commitment Increase shall purchase and assume from each existing Lender having Revolving Loans outstanding on such Incremental Credit Extension Date, without recourse or warranty, an
undivided interest and participation, to the extent of such Lender’s Ratable Portion of the new Revolving Credit Commitments (after giving effect to such Revolving Credit Commitment Increase), in the aggregate outstanding Revolving Loans, so as
to ensure that, on the Incremental Credit Extension Date after giving effect to such Revolving Credit Commitment Increase, each Revolving Lender is owed only its Ratable Portion of the Revolving Loans on such Incremental Credit Extension Date.

  
 2.2 Borrowing Procedures. 
  
 (a) Each Borrowing shall be made on notice given by the Borrower to the
Administrative Agent not later than 11:00 a.m. (New York time) (i) on the Business Day of the proposed Borrowing, in the case of a Borrowing of Base Rate Loans and (ii) three Business Days prior to the date of the proposed Borrowing, in
the case of a Borrowing of Eurodollar Rate Loans. Each such notice shall be in substantially the form of Exhibit A (Form of Notice of Borrowing) (a “Notice of Borrowing”), specifying (A) the date of such proposed
Borrowing, (B) the aggregate amount of such proposed Borrowing, (C) whether any portion of the proposed Borrowing will be of Base Rate Loans or Eurodollar Rate Loans and (D) for each Eurodollar Rate Loan, the initial Interest Period
or periods thereof. Loans shall be made as Base Rate Loans unless, subject to Section 2.13 (Special Provisions Governing Eurodollar Rate Loans), the Notice of Borrowing specifies that all or a portion thereof shall be Eurodollar
Rate Loans. Each Borrowing shall be in an aggregate amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof. 
  
 (b) The Administrative Agent shall give to each Lender prompt notice of the Administrative Agent’s receipt of a Notice of Borrowing and, if
Eurodollar Rate Loans are properly requested in such Notice of Borrowing, the applicable interest rate determined pursuant to 2.13(a) (Determination of Interest Rate). Each Lender shall, (x) before 2:00 p.m. (New York time) on the date
of the proposed Borrowing of Base Rate Loans and (y) before 11:00 a.m. (New York time) on the date of the proposed Borrowing of Eurodollar Rate Loans, make available to the Administrative Agent at its address referred to in Section 10.8
(Notices, Etc.), in immediately available funds, such Lender’s Ratable Portion of such proposed Borrowing. Upon fulfillment (or due waiver in accordance with Section 10.1) (i) on the Closing Date, of the applicable
conditions set forth in Section 4.1 (Conditions to Effectiveness) and (ii) at any time (including the Closing Date), of the applicable conditions set forth in Section 4.2 (Conditions Precedent to Each Extension of
Credit), and after the Administrative Agent’s receipt of such funds, the Administrative Agent shall make such funds available to the Borrower. 
  
 (c) Unless the Administrative Agent shall have received notice from a Lender prior to the date (in the case of a Eurodollar Rate Loan) or no later than
12:00 p.m. (New York time) on the 
  

 21 

 date (in the case of a Base Rate Loan) of any proposed Borrowing, that such Lender will not make available to the
Administrative Agent such Lender’s Ratable Portion of such Borrowing (or any portion thereof), the Administrative Agent may assume that such Lender has made such Ratable Portion available to the Administrative Agent on the date of such
Borrowing in accordance with this Section 2.2 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so
made such Ratable Portion available to the Administrative Agent, such Lender and the Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the
date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and
(ii) in the case of such Lender, the Federal Funds Rate for the first Business Day and thereafter at the interest rate applicable at the time to the Loans comprising such Borrowing. If such Lender shall repay to the Administrative Agent such
corresponding amount, such corresponding amount so repaid shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement. If the Borrower shall repay to the Administrative Agent such corresponding amount, such
payment shall not relieve such Lender of any obligation it may have hereunder to the Borrower. 
  
 (d) The failure of any Lender to make on the date specified any Loan or any payment required by it (such Lender being a “Non-Funding Lender”), including any payment in respect of its participation in
Letter of Credit Obligations, shall not relieve any other Lender of its obligations to make such Loan or payment on such date but no such other Lender shall be responsible for the failure of any Non-Funding Lender to make a Loan or payment required
under this Agreement. 
  
 2.3 Letters of Credit.

  
 (a) On the terms and subject to the conditions contained in
this Agreement, each Issuer agrees to Issue at the request of the Borrower and for the account of the Borrower one or more Letters of Credit from time to time on any Business Day during the period commencing on the Closing Date and ending on the

 (vii) such Letter of Credit is not a Standby Letter of Credit. 
  
 None of the Lenders (other than the Issuers in their capacity as such) shall have any obligation to Issue any Letter of Credit. 

 
 (b) In no event shall the expiration date of any Letter of Credit
(i) be more than one year after the date of issuance thereof or (ii) be less than five days prior to the Scheduled Termination Date; provided, however, that any Letter of Credit with a term less than or equal to one year may
provide for the renewal thereof for additional periods less than or equal to one year, as long as (x) on or before the expiration of each such term and each such period, the Borrower and the Issuer of such Letter or Credit shall have the option
to prevent such renewal and (y) neither the Issuer of such Letter of Credit nor the Borrower shall permit any such renewal to extend the expiration date of any Letter of Credit beyond the date set forth in clause (ii) above.

Subject to the satisfaction of the conditions set forth in this Section 2.3, the relevant Issuer shall, on the requested date, Issue a Letter of Credit on behalf of the Borrower in accordance with such Issuer’s usual and customary

Administrative Agent shall provide a copy to each Lender requesting the same) and the Borrower a schedule of Letters of Credit issued by it, in form and substance reasonably satisfactory to the Administrative Agent, setting forth the aggregate
Letter of Credit Obligations, in each case outstanding at the end of each month, and any information requested by the Borrower or the Administrative Agent relating thereto. 
  
 (g) Immediately upon the issuance by an Issuer of a Letter of Credit in accordance with the terms and conditions of this
Agreement, such Issuer shall be deemed to have sold and transferred to each Lender, and each Lender shall be deemed irrevocably and unconditionally to have purchased and received from such Issuer, without recourse or warranty, an undivided interest
and participation, to the extent of such Lender’s Ratable Portion, in such Letter of Credit and the obligations of the Borrower with respect thereto (including all Letter of Credit Obligations with respect thereto) and any security therefor and
guaranty pertaining thereto. 
  
 (h) The Borrower agrees to pay to
the Issuer of any Letter of Credit the amount of all Reimbursement Obligations owing to such Issuer under any Letter of Credit issued for its account no later than the date that is the next succeeding Business Day after the Borrower receives written
notice from such Issuer that payment has been made under such Letter of Credit (the “Reimbursement Date”), irrespective of any claim, set-off, defense or other right that the Borrower may have at any time against such Issuer or any
other Person. In the event that any Issuer makes any payment under any Letter of Credit and the Borrower shall not have repaid such amount to such Issuer pursuant to this clause (h) or any such payment by the Borrower is rescinded or set
aside for any reason, such Reimbursement Obligation shall be payable on demand with interest thereon computed (i) from the date on which such Reimbursement Obligation arose to the Reimbursement Date, at the rate of interest applicable during
such period to Revolving Loans that are Base Rate Loans and (ii) from the Reimbursement Date until the date of repayment in full, at the rate of interest applicable during such period to past due Revolving Loans that are Base Rate Loans, and
such Issuer shall promptly notify the Administrative Agent, which shall 
  

 24 

 promptly notify each Lender of such failure, and each Lender shall promptly and unconditionally pay to the Administrative
Agent for the account of such Issuer the amount of such Lender’s Ratable Portion of such payment in immediately available Dollars. If the Administrative Agent so notifies such Lender prior to 11:00 a.m. (New York time) on any Business Day, such
Lender shall make available to the Administrative Agent for the account of such Issuer its Ratable Portion of the amount of such payment on such Business Day in immediately available funds. Upon such payment by a Lender, such Lender shall, except
during the continuance of a Default or Event of Default under Section 8.1(f) (Events of Default) and notwithstanding whether or not the conditions precedent set forth in Section 4.2 (Conditions Precedent to Each Extension of
Credit) shall have been satisfied (which conditions precedent the Lenders hereby irrevocably waive), be deemed to have made a Revolving Loan to the Borrower in the principal amount of such payment. Whenever any Issuer receives from the Borrower
a payment of a Reimbursement Obligation as to which the Administrative Agent has received for the account of such Issuer any payment from a Lender pursuant to this clause (h), such Issuer shall pay over to the Administrative Agent any amount
received in respect of such Reimbursement Obligation and, upon receipt of such amount, the Administrative Agent shall promptly pay over to each Lender, in immediately available funds, an amount equal to such Revolving Credit Lender’s Ratable
Portion of the amount of such payment adjusted, if necessary, to reflect the respective amounts the Revolving Credit Lenders have paid in respect of such Reimbursement Obligation. 
  
 (i) If and to the extent such Lender shall not have so made its Ratable Portion of the amount of the payment required by
clause (h) above available to the Administrative Agent for the account of such Issuer, such Lender agrees to pay to the Administrative Agent for the account of such Issuer forthwith on demand any such unpaid amount together with interest
thereon, for the first Business Day after payment was first due at the Federal Funds Rate and, thereafter, until such amount is repaid to the Administrative Agent for the account of such Issuer, at a rate per annum equal to the rate applicable to
Base Rate Loans under the Facility. 
  
 (j) The Borrower’s
obligation to pay each Reimbursement Obligation and the obligations of the Lenders to make payments to the Administrative Agent for the account of the Issuers with respect to Letters of Credit shall be absolute, unconditional and irrevocable and
shall be performed strictly in accordance with the terms of this Agreement, under any and all circumstances whatsoever, including the occurrence of any Default or Event of Default, and irrespective of any of the following: 
  
 (i) any lack of validity or enforceability of any Letter of
Credit or any Loan Document, or any term or provision therein; 
  
 (ii) any amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit or any Loan Document; 
  
 (iii) the existence of any claim, set off, defense or other right that the Borrower, any other Loan Party,
any other party guaranteeing, or otherwise obligated with, the Borrower, any Subsidiary of a Loan Party or other Affiliate thereof or any other Person may at any time have against the beneficiary under any Letter of Credit, any Issuer, the
Administrative Agent or any Lender or any other Person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or transaction; 
  
 (iv) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent,
invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; 
  

 25 

 (v) payment by the Issuer under a Letter of Credit against presentation of a draft or
other document that does not comply with the terms of such Letter of Credit; and 
  
 (vi) any other act or omission to act or delay of any kind of the Issuer, the Lenders, the Administrative Agent or any other Person or any
other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.3, constitute a legal or equitable discharge of the Borrower’s obligations hereunder.

  
 Any action taken or omitted to be taken by the relevant Issuer under or in
connection with any Letter of Credit, if taken or omitted in the absence of gross negligence or willful misconduct, shall not result in any liability of such Issuer to the Borrower or any Lender. In determining whether drafts and other documents
presented under a Letter of Credit comply with the terms thereof, the Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary
and, in making any payment under any Letter of Credit, the Issuer may rely exclusively on the documents presented to it under such Letter of Credit as to any and all matters set forth therein, including reliance on the amount of any draft presented
under such Letter of Credit, whether or not the amount due to the beneficiary thereunder equals the amount of such draft and whether or not any document presented pursuant to such Letter of Credit proves to be insufficient in any respect, if such
document on its face appears to be in order, and whether or not any other statement or any other document presented pursuant to such Letter of Credit proves to be forged or invalid or any statement therein proves to be inaccurate or untrue in any
respect whatsoever, and any noncompliance in any immaterial respect of the documents presented under such Letter of Credit with the terms thereof shall, in each case, be deemed not to constitute willful misconduct or gross negligence of the Issuer.

  
 2.4 Reduction and Termination of the Commitments. The
Borrower may, upon at least three Business Days’ prior notice to the Administrative Agent, terminate in whole or reduce in part ratably the unused portions of the respective Revolving Credit Commitments of the Lenders; provided,
however, that each partial reduction shall be (a) in an aggregate amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof and (b) permanent and irrevocable. In addition, all outstanding Revolving
Credit Commitments shall terminate on the Revolving Credit Termination Date. 
  
 2.5 Repayment of Loans. The Borrower promises to repay the entire unpaid principal amount of the Revolving Loans on the Scheduled Termination Date, or earlier if otherwise required by the terms hereof.

  
 2.6 Evidence of Debt. 
  
 (a) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing Indebtedness of the Borrower to such Lender resulting from each Revolving Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under
this Agreement. 
  
 (b) (i) The Administrative
Agent, acting as agent of the Borrower solely for this purpose and for tax purposes, shall establish and maintain at its address referred to in Section 10.8 (Notices, Etc.) a record of ownership (the “Register”)
in which the Administrative Agent agrees to register by book entry the Administrative Agent’s, each Lender’s and each Issuer’s interest in each Revolving Loan, each Letter of Credit and each Reimbursement Obligation and in the right
to receive any payments hereunder and any assignment of any such interest or rights. In addition, the Administrative Agent, acting as agent of the Borrower solely for this purpose and for tax purposes, shall establish and maintain accounts in the
Register in accordance with its usual 
  

 26 

 practice in which it shall record (A) the names and addresses of the Lenders, (B) the Revolving
Credit Commitments of each Lender from time to time, (C) the amount of each Revolving Loan made and, if a Eurodollar Rate Loan, the Interest Period applicable thereto, (D) the amount of any drawn Letters of Credit, (E) the amount of
any principal or interest due and payable, and paid, by the Borrower to, or for the account of, each Lender hereunder, (F) the amount that is due and payable, and paid, by the Borrower to, or for the account of, each Issuer, including the
amount of Letter Credit Obligations (specifying the amount of any Reimbursement Obligations) due and payable to an Issuer, and (G) the amount of any sum received by the Administrative Agent hereunder from the Borrower, whether such sum
constitutes principal or interest (and the type of Revolving Loan to which it applies), fees, expenses or other amounts due under the Loan Documents and each Lender’s and Issuer’s, as the case may be, share thereof, if applicable.

  
 (ii) Notwithstanding anything to the contrary
contained in this Agreement, the Revolving Loans (including the Revolving Credit Notes evidencing such Revolving Loans) and the drawn Letters of Credit are registered obligations and the right, title, and interest of the Lenders and the Issuers and
their assignees in and to such Revolving Loans or drawn Letters of Credit, as the case may be, shall be transferable only upon notation of such transfer in the Register. A Revolving Credit Note shall only evidence the Lender’s or a registered
assignee’s right, title and interest in and to the related Revolving Loan, and in no event is any such Revolving Credit Note to be considered a bearer instrument or obligation. This Section 2.6(b) and Section 10.2
(Assignments and Participations) shall be construed so that the Revolving Loans and drawn Letters of Credit are at all times maintained in “registered form” within the meaning of Sections 163(f), 871(h)(2) and 881(c)(2) of the
Code and any related regulations (or any successor provisions of the Code or such regulations). 
  
 (c) The entries made in the Register and in the accounts therein maintained pursuant to clauses (a) and (b) above shall, to the
extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations recorded therein; provided, however, 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 obligations of the Borrower to repay the Revolving Loans in accordance with their terms. In addition, the Loan Parties, the Administrative Agent, the Lenders and the Issuers shall
treat each Person whose name is recorded in the Register as a Lender for all purposes of this Agreement. Information contained in the Register with respect to any Lender or Issuer shall be available for inspection by the Borrower, the Administrative
Agent, such Lender or such Issuer at any reasonable time and from time to time upon reasonable prior notice. 
  
 (d) Notwithstanding any other provision of the Agreement, in the event that any Lender requests that the Borrower execute and deliver a promissory note or
notes payable to such Lender in order to evidence the Indebtedness owing to such Lender by the Borrower hereunder, the Borrower shall promptly execute and deliver a Revolving Credit Note or Revolving Credit Notes to such Lender evidencing any
Revolving Loans of such Lender, substantially in the form of Exhibit E (Form of Revolving Credit Note). 
  

 27 

 2.7 Optional Prepayments. The Borrower may prepay the outstanding principal amount of the
Revolving Loans in whole or in part at any time; provided, however, that if any prepayment of any Eurodollar Rate Loan is made by the Borrower other than on the last day of an Interest Period for such Loan, the Borrower shall also pay any
amount owing pursuant to Section 2.13(e) (Breakage Costs). Partial prepayments of Revolving Loans shall be in an aggregate principal amount of not less than $5,000,000 or an integral multiple of $1,000,000 in excess thereof. 

 
 2.8 Mandatory Prepayments. If at any time, the aggregate principal
amount of Revolving Credit Outstandings exceeds the aggregate Revolving Credit Commitments at such time, the Borrower shall forthwith prepay the Revolving Loans then outstanding in an amount equal to such excess. If any such excess remains after
repayment in full of the aggregate outstanding Revolving Loans, the Borrower shall provide cash collateral for the then outstanding Letter of Credit Obligations in the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit)
in an amount equal to 105% of such excess. 
  
 2.9
Interest. 
  
 (a) Rate of Interest. All Revolving
Loans and the outstanding amount of all other Obligations shall bear interest, in the case of Revolving Loans, on the unpaid principal amount thereof from the date such Revolving Loans are made and, in the case of such other Obligations, from the
date such other Obligations are due and payable until, in all cases, paid in full, except as otherwise provided in clause (c) below, as follows: 
  
 (i) if a Base Rate Loan or such other Obligation, at a rate per annum equal to the sum of (A) the Base Rate as in effect from time to
time and (B) the Applicable Margin for Revolving Loans that are Base Rate Loans; and 
  
 (ii) if a Eurodollar Rate Loan, at a rate per annum equal to the sum of (A) the Eurodollar Rate determined for the applicable
Interest Period and (B) the Applicable Margin in effect from time to time during such Eurodollar Interest Period. 
  
 (b) Interest Payments. (i) Interest accrued on each Base Rate Loan shall be payable in arrears (A) on the first Business Day of each
calendar quarter, commencing on the first such day following the making of such Base Rate Loan, and (B) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Base Rate Loan, (ii) interest accrued on
each Eurodollar Rate Loan shall be payable in arrears (A) on the last day of each Interest Period applicable to such Loan (and, if such Interest Period has a duration of more than three months, on each date during such Interest Period occurring
every three months from the first day of such Interest Period), (B) upon the payment or prepayment thereof in full or in part and (C) if not previously paid in full, at maturity (whether by acceleration or otherwise) of such Eurodollar
Rate Loan, and (iii) interest accrued on the amount of all other Obligations shall be payable on demand from and after the time such Obligation becomes due and payable (whether by acceleration or otherwise). 
  
 (c) Default Interest. Notwithstanding the rates of interest specified
in clause (a) above or elsewhere herein, effective immediately upon the occurrence of an Event of Default specified in Section 8.1(a) and for as long thereafter as such Event of Default shall be continuing, the principal
balance of all Loans and the amount of all other Obligations then due and payable shall bear interest at a rate that is 2% per annum in excess of the rate of interest applicable to such Loans or other Obligations from time to time. Such
interest shall be payable on the date that would otherwise be applicable to such interest pursuant to clause (b) above or otherwise on demand. 
  

 28 

 2.10 Conversion/Continuation Option. 
  
 (a) The Borrower may elect (i) at any time on any Business Day to
convert Base Rate Loans or any portion thereof to Eurodollar Rate Loans and (ii) at the end of any applicable Interest Period, to convert Eurodollar Rate Loans or any portion thereof into Base Rate Loans or to continue such Eurodollar Rate
Loans or any portion thereof for an additional Interest Period; provided, however, that the aggregate amount of the Eurodollar Loans for each Interest Period must be in the amount of at least $5,000,000 or an integral multiple of
$1,000,000 in excess thereof. Each conversion or continuation shall be allocated among the Loans of each Lender in accordance with such Lender’s Ratable Portion. Each such election shall be in substantially the form of Exhibit F (a
“Notice of Conversion or Continuation”) and shall be made by giving the Administrative Agent at least three Business Days’ prior written notice specifying (A) the amount and type of Loan being converted or continued,
(B) in the case of a conversion to or a continuation of Eurodollar Rate Loans, the applicable Interest Period and (C) in the case of a conversion, the date of such conversion. 
  
 (b) The Administrative Agent shall promptly notify each Lender of its receipt of a Notice of Conversion or Continuation and
of the options selected therein. Notwithstanding the foregoing, no conversion in whole or in part of Base Rate Loans to Eurodollar Rate Loans and no continuation in whole or in part of Eurodollar Rate Loans upon the expiration of any applicable
Interest Period shall be permitted at any time at which (A) a Default or an Event of Default shall have occurred and be continuing or (B) the continuation of, or conversion into, a Eurodollar Rate Loan would violate any provision of
2.13 (Special Provisions Governing Eurodollar Rate Loans). If, within the time period required under the terms of this Section 2.10, the Administrative Agent does not receive a Notice of Conversion or Continuation from the
Borrower containing a permitted election to continue any Eurodollar Rate Loans for an additional Interest Period or to convert any such Loans, then, upon the expiration of the applicable Interest Period, such Loans shall be automatically converted
to Base Rate Loans. Each Notice of Conversion or Continuation shall be irrevocable. 
  
 2.11 Fees. 
  
 (a)
Facility Fee. The Borrower agrees to pay in immediately available Dollars to the Administrative Agent for the account of each Lender a fee (the “Facility Fee”) on the daily amount of such Lender’s Revolving Credit
Commitment, whether used or unused, and when the Revolving Credit Commitment has been terminated, on the Revolving Credit Outstandings of such Lender, at the Applicable Facility Fee Rate from the date hereof through the later of (i) the
Revolving Credit Termination Date and (ii) the date on which all outstanding Revolving Loans are paid in full and all Letter of Credit Obligations have been cash collateralized in an amount equal to 105% of such Letter of Credit Obligations in
the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit). All Facility Fees shall be payable in arrears (x) on the first Business Day of each calendar quarter, commencing on the first such Business Day following
the Closing Date, (y) on the Revolving Credit Termination Date and (z) on the date on which all outstanding Revolving Loans are paid in full and all Letter of Credit Obligations have been cash collateralized in an amount equal to 105% of
such Letter of Credit Obligations in the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit). 
  
 (b) Utilization Fee. The Borrower agrees to pay in immediately available Dollars to the Administrative Agent for the account of each Lender a fee
(the “Utilization Fee”) on such Lender’s Ratable Portion of the Revolving Credit Outstandings at the Utilization Fee Rate for each day on which the Revolving Credit Outstandings exceeds 50% of the aggregate Revolving Credit
Commitments, during the period from the date hereof through the later of (i) the Revolving Credit Termination Date and (ii) the date on which all outstanding Revolving Loans are paid in full and all Letter of Credit Obligations have been
cash collateralized in an amount equal to 105% of such Letter of Credit Obligations in the manner 
  

 29 

 set forth in Section 8.2 (Actions in Respect of Letters of Credit). All Utilization Fees shall be payable in
arrears (x) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the Closing Date, (y) on the Revolving Credit Termination Date and (z) on the date on which all outstanding Revolving
Loans are paid in full and all Letter of Credit Obligations have been cash collateralized in an amount equal to 105% of such Letter of Credit Obligations in the manner set forth in Section 8.2 (Actions in Respect of Letters of Credit).

  
 (c) Letter of Credit Fees. The Borrower agrees to pay
the following amounts with respect to Letters of Credit issued by any Issuer: 
  
 (i) to the Administrative Agent for the account of each Issuer of a Letter of Credit, with respect to each Letter of Credit issued by such Issuer, an issuance fee equal to 0.10% per annum of the maximum
undrawn face amount of such Letter of Credit, payable in arrears (A) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the issuance of such Letter of Credit and (B) on the Revolving
Credit Termination Date; 
  
 (ii) to the
Administrative Agent for the ratable benefit of the Lenders, with respect to each Letter of Credit, a fee accruing in Dollars at a rate per annum equal to the Applicable Margin for Revolving Loans that are Eurodollar Rate Loans on the maximum
undrawn face amount of such Letter of Credit, payable in arrears (A) on the first Business Day of each calendar quarter, commencing on the first such Business Day following the issuance of such Letter of Credit and (B) on the Revolving
Credit Termination Date; provided, however, that during the continuance of an Event of Default, such fee shall be increased by two percent per annum (instead of, and not in addition to, any increase pursuant to Section 2.9(c)
(Default Interest)) and shall be payable on demand; and 
  
 (iii) to the Issuer of any Letter of Credit, with respect to the issuance, amendment or transfer of each Letter of Credit and each drawing made thereunder, documentary and processing charges in accordance with such
Issuer’s standard schedule for such charges in effect at the time of issuance, amendment, transfer or drawing, as the case may be. 
  
 (d) Additional Fees. The Borrower has agreed to pay to the Administrative Agent and the Arrangers additional fees, the amount and dates of payment
of which are embodied in the Fee Letter. 
  
 2.12 Payments and
Computations. 
  
 (a) The Borrower shall make each payment
hereunder (including fees and expenses) not later than 11:00 a.m. (New York time) on the day when due, in Dollars, to the Administrative Agent at its address referred to in Section 10.8 (Notices, Etc.) in immediately available funds
without set-off or counterclaim. The Administrative Agent shall promptly thereafter cause to be distributed in immediately available funds relating to the payment of principal, interest or fees to the Lenders, in accordance with the application of
payments set forth in clause (f) for the account of their respective Applicable Lending Offices; provided, however, that amounts payable pursuant to Sections 2.14 (Capital Adequacy), 2.15 (Taxes) or
2.13(c) or (d) (Special Provisions Governing Eurodollar Rate Loans) shall be paid only to the affected Lender or Lenders. Payments received by the Administrative Agent after 11:00 a.m. (New York time) shall be deemed to be
received on the next Business Day. 
  
 (b) All computations of
interest in respect of interest at the Base Rate shall be made by the Administrative Agent on the basis of a 365/366-day year and actual days elapsed; all other 
  

 30 

 computations of interest and of fees shall be made by the Administrative Agent on the basis of a year of 360 days, in
each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest and fees are payable. Each determination by the Administrative Agent of a rate of interest hereunder shall
be conclusive and binding for all purposes, absent manifest error. 
  
 (c) Each payment by the Borrower of any Loan, Reimbursement Obligation (including interest or fees in respect thereof) and each reimbursement of various costs, expenses or other Obligation shall be made in Dollars. 
  
 (d) Whenever any payment hereunder shall be stated to be due on a day other
than a Business Day, the due date for such payment shall be extended to the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be;
provided, however, that if such extension would cause payment of interest on or principal of any Eurodollar Rate Loan to be made in the next calendar month, such payment shall be made on the immediately preceding Business Day. All
repayments of any Revolving Loans shall be applied as follows: first, to repay such Loans outstanding as Base Rate Loans and then, to repay such Loans outstanding as Eurodollar Rate Loans, with those Eurodollar Rate Loans having
earlier expiring Eurodollar Interest Periods being repaid prior to those having later expiring Eurodollar Interest Periods. 
  
 (e) Unless the Administrative Agent shall have received notice from the Borrower to the Lenders prior to the date on which any payment is due hereunder
that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption,
cause to be distributed to each Lender on such due date an amount equal to the amount then due such Lender. If and to the extent that the Borrower shall not have made such payment in full to the Administrative Agent, each Lender shall repay to the
Administrative Agent forthwith on demand such amount distributed to such Lender together with interest thereon (at the Federal Funds Rate for the first Business Day and thereafter, at the rate applicable to Base Rate Loans) for each day from the
date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent. 
  
 (f) Except for payments and other amounts received by the Administrative Agent and applied in accordance with the provisions of clause
(g) below, all payments and any other amounts received by the Administrative Agent from or for the benefit of the Borrower shall be applied as follows: first, to pay principal of, and interest on, any portion of the Loans the
Administrative Agent may have advanced pursuant to the express provisions of this Agreement on behalf of any Lender, for which the Administrative Agent has not then been reimbursed by such Lender or the Borrower, second, to pay all other
Obligations then due and payable and third, as the Borrower so designates. Payments in respect of Revolving Loans received by the Administrative Agent shall be distributed to each Lender in accordance with such Lender’s Ratable Portion
of the Revolving Credit Commitments and all payments of fees and all other payments in respect of any other Obligation shall be allocated among such of the Lenders as are entitled thereto and, for such payments allocated to the Lenders, in
proportion to their respective Ratable Portions. 
  
 (g) The
Borrower hereby irrevocably waives the right to direct the application of any and all payments in respect of the Obligations after the occurrence and during the continuance of an Event of Default and agrees that, notwithstanding the provisions of
clause (f) above, the Administrative Agent may, and, upon either (A) the written direction of the Required Lenders or (B) the acceleration of the Obligations pursuant to Section 8.1, shall, apply all payments in
respect of any Obligations in the following order: 
  
 (i) first, to pay interest on and then principal of any portion of the Revolving Loans that the Administrative Agent may have advanced on behalf of any Lender for which the Administrative Agent has not then been reimbursed by such
Lender or the Borrower; 
  

 31 

 (ii) second, to pay Obligations in respect of any expense reimbursements or
indemnities then due to the Administrative Agent; 
  
 (iii) third, to pay Obligations in respect of any expense reimbursements or indemnities then due to the Lenders and the Issuers; 
  
 (iv) fourth, to pay Obligations in respect of any fees then due to the Administrative Agent, the Lenders and the Issuers;

  
 (v) fifth, to pay interest then due
and payable in respect of the Revolving Loans and Reimbursement Obligations; 
  
 (vi) sixth, to pay or prepay principal amounts on the Revolving Loans and Reimbursement Obligations and to provide cash collateral for outstanding Letter of Credit Undrawn Amounts in the manner described in
Section 8.2 (Actions in Respect of Letters of Credit), ratably to the aggregate principal amount of such Loans, Reimbursement Obligations and Letter of Credit Undrawn Amounts; and 
  
 (vii) seventh, to the ratable payment of all other
Obligations; 
  
 provided, however, that if sufficient funds are not
available to fund all payments to be made in respect of any Obligation described in any of clauses (i) through (vii) above, the available funds being applied with respect to any such Obligation (unless otherwise specified in
such clause) shall be allocated to the payment of such Obligation ratably, based on the proportion of the Administrative Agent’s and each Lender’s or Issuer’s interest in the aggregate outstanding Obligations described in such
clauses. The order of priority set forth in clauses (i) through (vii) above may at any time and from time to time be changed by the agreement of the Required Lenders without necessity of notice to or consent of or approval by
the Borrower or by any other Person that is not a Lender or Issuer. The order of priority set forth in clauses (i) through (iv) above may be changed only with the prior written consent of the Administrative Agent in addition
to that of the Required Lenders. 
  
 (h) At the option of the
Administrative Agent, Reimbursement Obligations, interest, fees, expenses and other sums due and payable in respect of the Revolving Loans may be paid from the proceeds of Revolving Loans. The Borrower hereby authorizes the Lenders to make such
Revolving Loans pursuant to Section 2.2(a) (Borrowing Procedures) from time to time in the amounts of any and all Reimbursement Obligations, interest, fees, expenses and other sums payable in respect of the Revolving Loans, and further
authorizes the Administrative Agent to give the Lenders notice of any Borrowing with respect to such Revolving Loans and to distribute the proceeds of such Revolving Loans to pay such amounts. The Borrower agrees that all such Revolving Loans so
made shall be deemed to have been requested by it (irrespective of the satisfaction of the conditions in Section 4.2 (Conditions Precedent to Each Extension of Credit), which conditions the Lenders irrevocably waive) and directs that all
proceeds thereof shall be used to pay such amounts. 
  
 2.13
Special Provisions Governing Eurodollar Rate Loans. 
  
 (a) Determination of Interest Rate. The Eurodollar Rate for each Interest Period for Eurodollar Rate Loans shall be determined by the Administrative Agent pursuant to the procedures set forth in the definition of “Eurodollar
Rate.” The Administrative Agent’s determination shall be presumed to be correct absent manifest error and shall be binding on the Borrower. 
  

 32 

 (b) Interest Rate Unascertainable, Inadequate or Unfair. In the event that (i) the
Administrative Agent determines that adequate and fair means do not exist for ascertaining the applicable interest rates by reference to which the Eurodollar Rate then being determined is to be fixed or (ii) the Required Lenders notify the
Administrative Agent that the Eurodollar Rate for any Interest Period will not adequately reflect the cost to the Lenders of making or maintaining such Loans for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower
and the Lenders, whereupon each Eurodollar Loan shall automatically, on the last day of the current Interest Period for such Loan, convert into a Base Rate Loan and the obligations of the Lenders to make Eurodollar Rate Loans or to convert Base Rate
Loans into Eurodollar Rate Loans shall be suspended until the Administrative Agent shall notify the Borrower that the Required Lenders have determined that the circumstances causing such suspension no longer exist. 
  
 (c) Increased Costs. If at any time any Lender determines that the
introduction of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order occurring after the date hereof (other than any change by way of imposition or increase of reserve requirements included in
determining the Eurodollar Rate) or the compliance by such Lender with any guideline, request or directive from any central bank or other Governmental Authority issued after the date hereof (whether or not having the force of law), shall have the
effect of increasing the cost to such Lender of agreeing to make or making, funding or maintaining any Eurodollar Rate Loans, then the Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to the Administrative
Agent), pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the
Administrative Agent by such Lender, shall be conclusive and binding for all purposes, absent manifest error. The Borrower shall not be required to compensate a Lender pursuant to this Section 2.13(c) for any increased costs incurred
more than 90 days prior to the date that such Lender notifies the Borrower of the change in law giving rise to such increased costs and of such Lender’s intention to claim compensation therefor; provided, however, that if the
change in law giving rise to such increased costs is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof (to the extent that such period of retroactive effect is not already
included in such 90-day period). 
  
 (d) Illegality.
Notwithstanding any other provision of this Agreement, if any Lender determines that the introduction of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order after the date of this Agreement shall
make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Lender or its Eurodollar Lending Office to make Eurodollar Rate Loans or to continue to fund or maintain Eurodollar Rate Loans, then, on
notice thereof and demand therefor by such Lender to the Borrower through the Administrative Agent, (i) the obligation of such Lender to make or to continue Eurodollar Rate Loans and to convert Base Rate Loans into Eurodollar Rate Loans shall
be suspended, and each such Lender shall make a Base Rate Loan as part of any requested Borrowing of Eurodollar Rate Loans and (ii) if the affected Eurodollar Rate Loans are then outstanding, the Borrower shall immediately convert each such
Loan into a Base Rate Loan. If, at any time after a Lender gives notice under this clause (d), such Lender determines that it may lawfully make Eurodollar Rate Loans, such Lender shall promptly give notice of that determination to the
Borrower and the Administrative Agent, and the Administrative Agent shall promptly transmit the notice to each other Lender. The Borrower’s right to request, and such Lender’s obligation, if any, to make Eurodollar Rate Loans shall
thereupon be restored. 
  

 33 

 (e) Breakage Costs. In addition to all amounts required to be paid by the Borrower pursuant to
Section 2.9 (Interest), the Borrower shall compensate each Lender, upon demand, for all losses, expenses and liabilities (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund or maintain such Lender’s Eurodollar Rate Loans to the Borrower but excluding any loss of the Applicable Margin on the relevant Loans) that such Lender may sustain (i) if for any reason (other than solely by
reason of such Lender being a Non-Funding Lender) a proposed Borrowing, conversion into or continuation of Eurodollar Rate Loans does not occur on a date specified therefor in a Notice of Borrowing or a Notice of Conversion or Continuation given by
the Borrower or in a telephonic request by it for borrowing or conversion or continuation or a successive Interest Period does not commence after notice therefor is given pursuant to Section 2.10 (Conversion/Continuation Option),
(ii) if for any reason any Eurodollar Rate Loan is prepaid (including mandatorily pursuant to Section 2.8) on a date that is not the last day of the applicable Interest Period, (iii) as a consequence of a required conversion of
a Eurodollar Rate Loan to a Base Rate Loan as a result of any of the events indicated in clause (d) above or (iv) as a consequence of any failure by the Borrower to repay Eurodollar Rate Loans when required by the terms hereof. The
Lender making demand for such compensation shall deliver to the Borrower concurrently with such demand a written statement as to such losses, expenses and liabilities, and this statement shall be prima facie evidence as to the amount of
compensation due to such Lender, absent manifest error. 
  
 2.14
Capital Adequacy. If at any time any Lender determines that (a) the adoption of, or any change in or in the interpretation of, any law, treaty or governmental rule, regulation or order after the date of this Agreement regarding capital
adequacy, (b) compliance with any such law, treaty, rule, regulation or order or (c) compliance with any guideline or request or directive from any central bank or other Governmental Authority issued after the date hereof (whether or not
having the force of law) shall have the effect of reducing the rate of return on such Lender’s (or any corporation controlling such Lender’s) capital as a consequence of its obligations hereunder or under or in respect of any Letter of
Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change, compliance or interpretation, then, upon demand from time to time by such Lender (with a copy of such demand to the Administrative
Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender, from time to time as specified by such Lender, additional amounts sufficient to compensate such Lender for such reduction. A certificate as to such amounts
submitted to the Borrower and the Administrative Agent by such Lender shall be conclusive and binding for all purposes absent manifest error. The Borrower shall not be required to compensate a Lender pursuant to this Section 2.14 for any
reduced rate of return incurred more than 90 days prior to the date that such Lender notifies the Borrower of the change in law giving rise to such reduced rate of return and of such Lender’s intention to claim compensation therefor;
provided, however, that if the change in law giving rise to such reduction is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof (to the extent that such period
of retroactive effect is not already included in such 90-day period). 
  
 2.15 Taxes. 
  
 (a) Except as otherwise provided
in this Section 2.15, any and all payments by any Loan Party under each Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding (i) in the case of each Lender, each Issuer and the Administrative Agent (A) taxes measured by its net income, and franchise taxes imposed on it, and similar taxes imposed by the
jurisdiction (or any political subdivision thereof) under the laws of which such Lender, such Issuer or the Administrative Agent (as the case may be) is organized or in which its principal office is located or, in the case of any Lender, in which
its Applicable Lending Office is located and (B) any U.S. withholding taxes payable with respect to payments under the Loan Documents under laws (including any statute, treaty or 
  

 34 

 regulation) in effect on the Closing Date (or, in the case of (x) an Eligible Assignee, the date of the Assignment
and Acceptance, (y) a successor Administrative Agent, the date of the appointment of such Administrative Agent, and (z) a successor Issuer, the date such Issuer becomes an Issuer) applicable to such Lender, such Issuer or the
Administrative Agent, as the case may be, or is attributable to such Non-U.S. Lender’s failure to comply with Section 2.15(f), but not excluding any U.S. withholding taxes payable as a result of any change in such laws occurring
after the Closing Date (or the date of such Assignment and Acceptance or the date of such appointment of such Administrative Agent or the date such Issuer becomes an Issuer) and (ii) in the case of each Lender or each Issuer, taxes measured by
its net income, and franchise taxes imposed on it as a result of a present or former connection between such Lender or such Issuer (as the case may be) and the jurisdiction of the Governmental Authority imposing such tax or any taxing authority
thereof or therein (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If any Taxes shall be required by law to be deducted from or in respect
of any sum payable under any Loan Document to any Lender, any Issuer or the Administrative Agent (w) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.15, such Lender, such Issuer or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (x) the relevant
Loan Party shall make such deductions, (y) the relevant Loan Party shall pay the full amount deducted to the relevant taxing authority or other authority in accordance with applicable law and (z) the relevant Loan Party shall deliver to
the Administrative Agent evidence of such payment. 
  
 (b) In
addition, each Loan Party agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies of the United States or any political subdivision thereof or any applicable foreign
jurisdiction, and all liabilities with respect thereto, in each case arising from any payment made under any Loan Document or from the execution, delivery or registration of, or otherwise with respect to, any Loan Document (collectively,
“Other Taxes”). 
  
 (c) Each Loan Party shall,
jointly and severally, indemnify each Lender, each Issuer and the Administrative Agent for the full amount of Taxes and Other Taxes (including any Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.15) paid by such Lender, such Issuer or the Administrative Agent (as the case may be) and any liability (including for penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other
Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such Lender, such Issuer or the Administrative Agent (as the case may be) makes written demand therefor. 
  
 (d) Within 30 days after the date of any payment of Taxes or Other Taxes by
any Loan Party, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 10.8 (Notices, Etc.), the original or a certified copy of a receipt evidencing payment thereof. 
  
 (e) Without prejudice to the survival of any other agreement of any Loan
Party hereunder or under the Guaranty, the agreements and obligations of such Loan Party contained in this Section 2.15 shall survive the payment in full of the Obligations. 
  
 (f) Each Non-U.S. Lender that is entitled to an exemption from U.S. withholding tax, or that is subject to such tax at
a reduced rate under an applicable tax treaty, shall (v) on or prior to the Closing Date in the case of each Non-U.S. Lender that is a signatory hereto, (w) on or prior to the date of the Assignment and Acceptance pursuant to which such
Non-U.S. Lender becomes a Lender, on or prior to the date a successor Issuer becomes an Issuer or the date a successor Administrative Agent becomes the Administrative Agent hereunder, (x) on or prior to the date on which any such form or

  

 35 

 certification expires or becomes obsolete, (y) after the occurrence of any event requiring a change in the most
recent form or certification previously delivered by it to the Borrower and the Administrative Agent, and (z) from time to time thereafter if requested by the Borrower or the Administrative Agent, provide the Administrative Agent and the
Borrower with two completed originals of each of the following, as applicable: 
  
 (i) (A) Form W-8ECI (claiming exemption from U.S. withholding tax because the income is effectively connected with a U.S. trade or
business) or any successor form, (B) Form W-8BEN (claiming exemption from, or a reduction of, U.S. withholding tax under an income tax treaty) or any successor form, (C) in the case of a Non-U.S. Lender claiming exemption under Sections
871(h) or 881(c) of the Code, a Form W-8BEN (claiming exemption from U.S. withholding tax under the portfolio interest exemption) or any successor form or (D) any other applicable form, certificate or document prescribed by the IRS certifying
as to such Non-U.S. Lender’s entitlement to such exemption from U.S. withholding tax or reduced rate with respect to all payments to be made to such Non-U.S. Lender under the Loan Documents. Unless the Borrower and the Administrative Agent have
received forms or other documents satisfactory to them indicating that payments under any Loan Document to or for a Non-U.S. Lender are not subject to U.S. withholding tax or are subject to such tax at a rate reduced by an applicable tax treaty, the
Loan Parties and the Administrative Agent shall withhold amounts required to be withheld by applicable Requirements of Law from such payments at the applicable statutory rate. 
  
 (ii) Each U.S. Lender shall (v) on or prior to the Closing Date in the case of each U.S. Lender that is
a signatory hereto, (w) on or prior to the date of the Assignment and Acceptance pursuant to which such U.S. Lender becomes a Lender or an Issuer or on or prior to the date a successor Administrative Agent becomes the Administrative Agent
hereunder, (x) on or prior to the date on which any such form or certification expires or becomes obsolete, (y) after the occurrence of any event requiring a change in the most recent form or certification previously delivered by it to the
Borrower and the Administrative Agent, and (z) from time to time if requested by the Borrower or the Administrative Agent, provide the Administrative Agent and the Borrower with two completed originals of Form W-9 (certifying that such U.S.
Lender is entitled to an exemption from U.S. backup withholding tax) or any successor form. Solely for purposes of this Section 2.15(f), a U.S. Lender shall not include a Lender, an Issuer or an Administrative Agent that may be treated
as an exempt recipient based on the indicators described in Treasury Regulation section 1.6049-4(c)(1)(ii). 
  
 (g) Any Lender claiming any additional amounts payable pursuant to this Section 2.15 shall use its reasonable efforts (consistent with its
internal policies and Requirements of Law) to change the jurisdiction of its Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that would be payable or may
thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such Lender. 
  
 (h) If any Lender, Issuer or the Administrative Agent, as determined in its reasonable discretion, ever receives any refund of or credit with respect to
any Taxes or Other Taxes as to which it has been indemnified by any Loan Party, or with respect to which any Loan Party has paid additional amounts pursuant to this Section 2.15, it shall pay over to such Loan Party an amount equal to
such refund or credit (but only to the extent of indemnity payments made, or additional amounts paid, by any Loan Party under this Section 2.15 with respect to the Taxes or Other Taxes giving rise to such refund or credit), net of all
out-of-pocket expenses of such Lender, Issuer or the Administrative Agent and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund or credit); provided that such Loan Party, upon
the request of such Lender, Issuer or the Administrative 
  

 36 

 Agent, agrees to repay the amount paid over to the Loan Party, to such Lender, Issuer or the Administrative Agent in the
event the Lender, Issuer or the Administrative Agent is required to repay such refund or credit to such Governmental Authority. This paragraph shall not be construed to require the Lender, Issuer or the Administrative Agent to make available its tax
returns (or any other information relating to its taxes which it deems confidential) to any Loan Party or any other Person. 
  
 2.16 Substitution of Lenders. 
  
 (a) In the event that (i)(A) any Lender makes a claim under Sections 2.13(c) (Increased Costs) or 2.14 (Capital Adequacy), (B) it
becomes illegal for any Lender to continue to fund or make any Eurodollar Rate Loan and such Lender notifies the Borrower pursuant to Section 2.13(d) (Illegality), (C) any Loan Party is required to make any payment pursuant to
Section 2.15 (Taxes) that is attributable to a particular Lender or (D) any Lender becomes a Non-Funding Lender, (ii) in the case of clause (i)(A) above, as a consequence of increased costs in respect of which such claim
is made, the effective rate of interest payable to such Lender under this Agreement with respect to its Loans materially exceeds the effective average annual rate of interest payable to the Required Lenders under this Agreement and (iii) in the
case of clause (i)(A),(B) and (C) above, Lenders holding at least 75% of the Commitments are not subject to such increased costs or illegality, payment or proceedings (any such Lender, an “Affected Lender”), the
Borrower may substitute any Lender and, if reasonably acceptable to the Administrative Agent, any other Eligible Assignee (a “Substitute Institution”) for such Affected Lender hereunder, after delivery of a written notice (a
“Substitution Notice”) by the Borrower to the Administrative Agent and the Affected Lender within a reasonable time (in any case not to exceed 90 days) following the occurrence of any of the events described in clause
(i) above that the Borrower intends to make such substitution; provided, however, that, if more than one Lender claims increased costs, illegality or right to payment arising from the same act or condition and such claims are
received by the Borrower within 30 days of each other, then the Borrower may substitute all, but not (except to the extent the Borrower has already substituted one of such Affected Lenders before the Borrower’s receipt of the other Affected
Lenders’ claim) less than all, Lenders making such claims. 
  
 (b) If the Substitution Notice was properly issued under this Section 2.16, the Affected Lender shall sell, and the Substitute Institution shall purchase, all rights and claims of such Affected Lender under the Loan Documents
and the Substitute Institution shall assume, and the Affected Lender shall be relieved of, the Affected Lender’s Revolving Credit Commitments and all other prior unperformed obligations of the Affected Lender under the Loan Documents (other
than in respect of any damages (which pursuant to Section 10.5 (Limitation of Liability), do not include exemplary or punitive damages, to the extent permitted by applicable law) in respect of any such unperformed obligations). Such
purchase and sale (and the corresponding assignment of all rights and claims hereunder) shall be recorded in the Register maintained by the Administrative Agent and shall be effective on (and not earlier than) the later of (i) the receipt by
the Affected Lender of its Ratable Portion of the Revolving Credit Outstandings, together with any other Obligations owing to it, (ii) the receipt by the Administrative Agent of an agreement in form and substance satisfactory to it and the
Borrower whereby the Substitute Institution shall agree to be bound by the terms hereof and (iii) the payment in full to the Affected Lender in cash of all fees, unreimbursed costs and expenses and indemnities accrued and unpaid through such
effective date. Upon the effectiveness of such sale, purchase and assumption, the Substitute Institution shall become a “Lender” hereunder for all purposes of this Agreement having a Revolving Credit Commitment in the amount of such
Affected Lender’s Revolving Credit Commitment assumed by it and such Revolving Credit Commitment of the Affected Lender shall be terminated; provided, however, that all indemnities under the Loan Documents shall continue in favor
of such Affected Lender. 
  
 (c) Each Lender agrees that, if it
becomes an Affected Lender and its rights and claims are assigned hereunder to a Substitute Institution pursuant to this Section 2.16, it shall execute and 
  

 37 

 deliver to the Administrative Agent an Assignment and Acceptance to evidence such assignment, together with any Revolving
Credit Note (if such Loans are evidenced by a Revolving Credit Note) evidencing the Loans subject to such Assignment and Acceptance; provided, however, that the failure of any Affected Lender to execute an Assignment and Acceptance
shall not render such assignment invalid. 
  
 SECTION 3.
REPRESENTATIONS AND WARRANTIES 
  
 To induce the Agents, the
Lenders and the Issuers to enter into this Agreement and to make the Revolving Loans and Issue or participate in the Letters of Credit, the MLP and the Borrower hereby represent and warrant to each Agent, each Lender and each Issuer that:

  
 3.1 Financial Condition. The audited consolidated
balance sheets of (a) the Borrower and its Subsidiaries, (b) Texas Gas and (c) Gulf South, each as at December 31, 2004, and the related audited consolidated statements of income and of cash flows for the period ended on such
date, reported on by and accompanied by an unqualified report from Deloitte & Touche LLP, present fairly the consolidated financial condition of the Borrower, Texas Gas and Gulf South, respectively, as at such date, and the consolidated
results of its operations and its consolidated cash flows for the period then ended. The unaudited consolidated balance sheets of (x) the Borrower and its Subsidiaries, (y) Texas Gas and (z) Gulf South, each as at June 30, 2005,
and the related unaudited consolidated statements of income and cash flows for the six-month period ended on such date, present fairly the consolidated financial condition of the Borrower, Texas Gas and Gulf South, respectively, as at such date, and
the consolidated results of its operations and its consolidated cash flows for the six-month period then ended (subject to normal year-end audit adjustments and the absence of notes). All such financial statements, including the related schedules
and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). 
  
 3.2 No Change. Since December 31, 2004 there has been no
development or event that has had or could reasonably be expected to have a Material Adverse Effect. 
  
 3.3 Corporate Existence; Compliance with Law. Each of the MLP, the Borrower and their respective Subsidiaries (a) is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its organization, (b) has the limited partnership, limited liability company, corporate or other power and authority, and the legal right, to own and operate its Property, to
lease the Property it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign limited partnership, limited liability company, corporation or other organization and in good standing
under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires such qualification and (d) is in compliance with all Requirements of Law except, in the case of clauses
(c) and (d), to the extent that the failure to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect. 
  
 3.4 Limited Partnership Power; Authorization; Enforceable Obligations. Each of the Loan Parties has the limited
partnership (or equivalent) power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, with respect to the Borrower, to borrow hereunder. Each of the Loan Parties has taken all necessary
limited partnership (or equivalent) or other necessary action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, with respect to the Borrower, to authorize the borrowings on the terms and
conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or the execution, delivery,
validity or enforceability of this Agreement or any of the other Loan Documents, except consents, authorizations, filings and notices described in Schedule 3.4, which 
  

 38 

 consents, authorizations, filings and notices have been obtained or made and are in full force and effect. No consent or
authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the performance of this Agreement or any of the other Loan Documents, except routine consents,
authorizations, filings and notices required to be made in the ordinary course of business. This Agreement has been, and, upon execution, each Loan Document shall have been, duly executed and delivered on behalf of each Loan Party that is a party
thereto. This Agreement constitutes, and each other Loan Document that is an agreement or instrument upon execution will constitute, a legal, valid and binding obligation of each Loan Party that is a party thereto, enforceable against such Loan
Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable
principles (whether enforcement is sought by proceedings in equity or at law). 
  
 3.5 No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or
any material Contractual Obligation of the MLP, the Borrower or their respective Subsidiaries and will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of
Law or any such Contractual Obligation. 
  
 3.6 No Material
Litigation. Except as set forth on Schedule 3.6, no litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or
any Borrower Affiliate, or against any of its or their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) that could reasonably be expected to
have a Material Adverse Effect. 
  
 3.7 No Default. No
Default or Event of Default has occurred and is continuing. 
  
 3.8 Ownership of Property; Liens. Each of the MLP, the Borrower and each of their respective Subsidiaries has title in fee simple to, or a valid leasehold interest in, or a right of way or easement in all real property used or
necessary for, and material to, the conduct of its business, and good title to, or a valid leasehold interest in, all its other Property used or necessary for, and material to, the conduct of its business, and none of such Property is subject to any
Lien except as permitted by Section 7.2. 
  
 3.9
Taxes. Each of the MLP, the Borrower and each of their respective Subsidiaries has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and payable
on said returns or on any assessments made against it or any of its Property and all other taxes, fees or other charges imposed on it or any of its Property by any Governmental Authority (other than any the amount or validity of which are currently
being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the MLP, the Borrower and their respective Subsidiaries or any amount the failure to pay could not
reasonably be expected to have a Material Adverse Effect); and no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge. 
  
 3.10 ERISA. Neither a Reportable Event nor an “accumulated
funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has occurred during the five year period prior to the date on which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all respects with the applicable provisions of ERISA and the Code, 
  

 39 

 except any such failures to comply that could not reasonably be expected to have a Material Adverse Effect. No
termination of a Single Employer Plan has occurred under Section 4041(c) or Section 4042 of ERISA, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each
Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits by an amount that could reasonably be expected to have a Material Adverse Effect. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or
could reasonably be expected to result in a material liability under ERISA, and neither the Borrower nor any Commonly Controlled Entity would become subject to any liability that could reasonably be expected to have a Material Adverse Effect if the
Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in
Reorganization or Insolvent. 
  
 3.11 Use of Proceeds. The
proceeds of the Revolving Loans shall be used solely for (a) the repayment on or around Closing Date of an intercompany loan by Boardwalk Pipelines Holding Corp. in an aggregate principal amount of $43,000,000 and (b) general partnership
purposes. The proceeds of the Letters of Credit shall be used solely for general partnership purposes. 
  
 3.12 Environmental Matters. Other than exceptions to any of the following that could not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect: 
  
 (a) The MLP, the Borrower
and each of their respective Subsidiaries: (i) is, and within the period of all applicable statutes of limitation has been, in compliance with all applicable Environmental Laws; (ii) holds all Environmental Permits (each of which is in
full force and effect) required for any of its current or intended operations or for any property owned, leased, or otherwise operated by it; and (iii) is, and within the period of all applicable statutes of limitation has been, in compliance
with all of its Environmental Permits. 
  
 (b) There is no
judicial, administrative, or arbitral proceeding (including any notice of violation or alleged violation) under or relating to any Environmental Law to which the MLP, the Borrower or any of their respective Subsidiaries is, or to the knowledge of
the Borrower will be, named as a party that is pending or, to the knowledge of the Borrower, threatened. 
  
 3.13 Accuracy of Information, etc. No statement or information (other than the projections and pro forma financial information referred to
in the following sentence) contained in this Agreement, any other Loan Document or any other material document or certificate furnished to the Administrative Agent or the Lenders or any of them, by or on behalf of the MLP, the Borrower or any of
their respective Subsidiaries for use in connection with the transactions contemplated by this Agreement or the other Loan Documents (as modified or supplemented by other information so furnished on or before the time this representation is made or
deemed made with respect thereto), contained as of the date such statement, information, document or certificate was so furnished, any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements
contained herein or therein not misleading. The projections and pro forma financial information contained in the materials referenced above are based upon good faith estimates and assumptions believed by management of the Borrower to be
reasonable at the time made, it being recognized by the Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may
differ from the projected results set forth therein by a material amount. 
  

 40 

 3.14 Solvency. Both before and after giving effect to (a) the Revolving Loans and Letter of
Credit Obligations to be made or extended on the Closing Date or such other date as Revolving Loans and Letter of Credit Obligations requested hereunder are made or extended, (b) the disbursement of the proceeds of such Revolving Loans pursuant
to the instructions of the Borrower, and (c) the payment and accrual of all transaction costs in connection with the foregoing, each Loan Party is Solvent. 
  

3.15 Subsidiaries; Borrower Information. (a) Set forth on Schedule 3.15(a) is a complete and accurate list showing, as of the
Closing Date, all Subsidiaries of the MLP and the Borrower. Schedule 3.15(a) sets forth as of the Closing Date the name and jurisdiction of organization of each such Subsidiary, and as to each such Subsidiary, the percentage of each class of
Capital Stock owned by each Loan Party. As of the Closing Date, there are no outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments (other than stock options granted to employees or directors and
directors’ qualifying shares) of any nature relating to any Capital Stock of the MLP, the Borrower or any of their respective Subsidiaries, except as disclosed on Schedule 3.15(a). 
  
 (b) Schedule 3.15(b) sets forth as of the Closing Date the name,
address of principal place of business and tax identification number of the Borrower. 
  
 3.16 Margin Regulations. The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U of the Federal Reserve Board),
and no proceeds of any Revolving Loan will be used to purchase or carry any such margin stock or to extend credit to others for the purpose of purchasing or carrying any such margin stock in contravention of Regulation T, U or X of the Federal
Reserve Board. 
  
 3.17 Investment Company Act; Public Utility
Holding Company Act. None of the MLP, the Borrower or any of their respective Subsidiaries is (a) an “investment company” or an “affiliated person” of, or “promoter” or “principal
underwriter” for, an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended, or (b) at any time prior to February 8, 2006, a “holding company” or an
“affiliate” of a “holding company” or a “subsidiary company” of a “holding company”, as each such term is defined and used in the Public Utility Holding Company Act of 1935, as
amended. 
  
 3.18 Insurance. All policies of insurance of
any kind or nature of the Borrower or any of its Subsidiaries, including policies of life, fire, theft, product liability, public liability, property damage, other casualty, employee fidelity, workers’ compensation and employee health and
welfare insurance, are in full force and effect and are of a nature and provide such coverage as is customarily carried by businesses of the size and character of such Person.

entered into for the disposition of such property, provided that such disposition is otherwise permitted hereunder and (G) constituting any encumbrance or restriction contained in the Constituent Documents of any Subsidiary that subjects the

 (a) any transaction that is (i) otherwise permitted under this Agreement, (ii) in the ordinary course of business of the Borrower or such Subsidiary, and (iii) upon fair and reasonable terms no less favorable to the Borrower

required by GAAP or any Requirement of Law and disclosed to the Lenders and the Administrative Agent or (b) Fiscal Year or Fiscal Quarters, except with the consent of the Administrative Agent; provided, however, that the Borrower
shall enter into such amendments to this Agreement as the Administrative Agent shall request to reflect such change in its Fiscal Year or Fiscal Quarters, as applicable, such that the applicable provisions of this Agreement affected by such change
shall have the same effect (or, in any case, be substantively no less favorable to the Lenders, in the determination of the Administrative Agent) after giving effect thereto as if such change were not made. 
  
 7.11 Limitation on Modification of Constituent Documents. Not modify
or amend its Constituent Documents, except for modifications and amendments that (a) could not reasonably be expected to have a Material Adverse Effect and (b) do not materially affect the interests of the Administrative Agent and the

 then, and in any such event, (A) if such event is an Event of Default specified in clause (i) or (ii) of paragraph (f) above,
automatically the Revolving Credit Commitments shall immediately terminate and the Revolving Loans (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents (including, without limitation, all

the Borrower declare the Revolving Credit Commitments to be terminated forthwith, whereupon the Revolving Credit Commitments shall immediately terminate, and (ii) with the consent of the Required Lenders, the Administrative Agent may, or upon
the request of the Required Lenders, the Administrative Agent shall, by notice to the Borrower, declare the Revolving Loans hereunder (with accrued interest thereon) and all other amounts owing under this Agreement and the other Loan Documents
(including, without limitation, all amounts of Letter of Credit Obligations, whether or not the beneficiaries of the then outstanding Letters of Credit shall have presented the documents required thereunder) to be due and payable forthwith,

payment of any amounts, in accordance with Section 2.12(f) (Payments and Computations), as shall have become or shall become due and payable by the Borrower to the Issuers or Lenders in respect of the Letter of Credit Obligations. The
Administrative Agent shall promptly give written notice of any such application; provided, however, that the failure to give such written notice shall not invalidate any such application. 
  
 SECTION 9. THE AGENTS 
  
 9.1 Authorization and Action. 
  
 (a) Each Lender and each Issuer hereby appoints Citibank as the
Administrative Agent hereunder and each Lender and each Issuer authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as 
  

 54 

 are delegated to the Administrative Agent under such agreements and to exercise such powers as are reasonably incidental
thereto. Without limiting the foregoing, each Lender and each Issuer hereby authorizes the Administrative Agent to execute and deliver, and to perform its obligations under, each of the Loan Documents to which the Administrative Agent is a party, to
exercise all rights, powers and remedies that the Administrative Agent may have under such Loan Documents. 
  
 (b) As to any matters not expressly provided for by this Agreement and the other Loan Documents (including enforcement or collection), the Administrative
Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Lenders,
and such instructions shall be binding upon all Lenders and all Issuers; provided, however, that the Administrative Agent shall not be required to take any action that (i) the Administrative Agent in good faith believes exposes it
to personal liability unless the Administrative Agent receives an indemnification satisfactory to it from the Lenders and the Issuers with respect to such action or (ii) is contrary to this Agreement or applicable law. The Administrative Agent
agrees to give to each Lender and each Issuer prompt notice of each notice given to it by any Loan Party pursuant to the terms of this Agreement or the other Loan Documents. 
  
 (c) In performing its functions and duties hereunder and under the other Loan Documents, the Administrative Agent is acting
solely on behalf of the Lenders and the Issuers except to the limited extent provided in 2.6(b), and its duties are entirely administrative in nature. The Administrative Agent does not assume and shall not be deemed to have assumed any
obligation other than as expressly set forth herein and in the other Loan Documents or any other relationship as the agent, fiduciary or trustee of or for any Lender, Issuer or holder of any other Obligation. The Administrative Agent may perform any
of its duties under any Loan Document by or through its agents or employees. 
  
 9.2 Administrative Agent’s Reliance, Etc. None of the Administrative Agent, any of its Affiliates or any of their respective directors, officers, agents or employees shall be liable for any action taken or
omitted to be taken by it, him, her or them under or in connection with this Agreement or the other Loan Documents, except for its, his, her or their own gross negligence or willful misconduct. Without limiting the foregoing, the Administrative
Agent (a) may treat the payee of any Revolving Credit Note as its holder until such Revolving Credit Note has been assigned in accordance with Section 10.2 (Assignments and Participations), (b) may rely on the Register to the
extent set forth in Section 2.6 (Evidence of Debt), (c) may consult with legal counsel (including counsel to the Borrower or any other Loan Party), independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts, (d) makes no warranty or representation to any Lender or Issuer and shall not be responsible to any
Lender or Issuer for any statements, warranties or representations made by or on behalf of the MLP, the Borrower or any of the Borrower’s Subsidiaries in or in connection with this Agreement or any other Loan Document, (e) shall not have
any duty to ascertain or to inquire either as to the performance or observance of any term, covenant or condition of this Agreement or any other Loan Document, as to the financial condition of any Loan Party or as to the existence or possible
existence of any Default or Event of Default, (f) shall not be responsible to any Lender or Issuer for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of, or the attachment, perfection or priority of any
Lien created or purported to be created under or in connection with, this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto or thereto and (g) shall incur no liability under or in respect of this
Agreement or any other Loan Document by acting upon any notice, consent, certificate or other instrument or writing (which writing may be a telecopy or electronic mail) or any telephone message believed by it to be genuine and signed or sent by the
proper party or parties. 
  

 55 

 9.3 Posting of Approved Electronic Communications. 
  
 (a) Each of the Lenders, the Issuers, the Borrower and the MLP agree that
the Administrative Agent may, but shall not be obligated to, make the Approved Electronic Communications available to the Lenders and the Issuers by posting such Approved Electronic Communications on IntraLinksTM or a substantially similar
electronic platform chosen by the Administrative Agent to be its electronic transmission system (the “Approved Electronic Platform”). 
  
 (b) Although the Approved Electronic Platform and its primary web portal are secured with generally-applicable security procedures and policies
implemented or modified by the Administrative Agent from time to time (including, as of the Closing Date, a dual firewall and a User ID/Password Authorization System) and the Approved Electronic Platform is secured through a single-user-per-deal
authorization method whereby each user may access the Approved Electronic Platform only on a deal-by-deal basis, each of the Lenders, the Issuer, the Borrower and the MLP acknowledges and agrees that the distribution of material through an
electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution. In consideration for the convenience and other benefits afforded by such distribution and for the other consideration
provided hereunder, the receipt and sufficiency of which is hereby acknowledged, each of the Lenders, the Issuers, the Borrower and the MLP hereby approves distribution of the Approved Electronic Communications through the Approved Electronic
Platform and understands and assumes the risks of such distribution. 
  
 (c) THE APPROVED ELECTRONIC PLATFORM AND THE APPROVED ELECTRONIC COMMUNICATIONS ARE PROVIDED “AS IS” AND “AS AVAILABLE”. NONE OF THE ADMINISTRATIVE AGENT OR ANY OF ITS AFFILIATES OR ANY OF THEIR RESPECTIVE OFFICERS,
DIRECTORS, EMPLOYEES, AGENTS, ADVISORS OR REPRESENTATIVES (THE “AGENT AFFILIATES”) WARRANT THE ACCURACY, ADEQUACY OR COMPLETENESS OF THE APPROVED ELECTRONIC COMMUNICATIONS OR THE APPROVED ELECTRONIC PLATFORM AND EACH EXPRESSLY
DISCLAIMS LIABILITY FOR ERRORS OR OMISSIONS IN THE APPROVED ELECTRONIC PLATFORM AND THE APPROVED ELECTRONIC COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING, WITHOUT LIMITATION, ANY WARRANTY OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY THE AGENT AFFILIATES IN CONNECTION WITH THE APPROVED ELECTRONIC PLATFORM OR THE APPROVED ELECTRONIC COMMUNICATIONS.

  
 (d) Each of the Lenders, the Issuers, the Borrower and the MLP
agree that the Administrative Agent may, but (except as may be required by applicable law) shall not be obligated to, store the Approved Electronic Communications on the Approved Electronic Platform in accordance with the Administrative Agent’s
generally-applicable document retention procedures and policies. 
  
 9.4 The Administrative Agent Individually. With respect to its Ratable Portion, Citibank shall have and may exercise the same rights and powers hereunder and is subject to the same obligations and liabilities as and to the extent set
forth herein for any other Lender. The terms “Lenders”, “Required Lenders” and any similar terms shall, unless the context clearly otherwise indicates, include, without limitation, the Administrative Agent in its
individual capacity as a Lender or as one of the Required Lenders. Citibank and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of banking, trust or other business with, any Loan Party as if Citibank were not
acting as the Administrative Agent. 
  

 56 

 9.5 Lender Credit Decision. Each Lender and each Issuer acknowledges that it shall, independently
and without reliance upon the Administrative Agent or any other Lender, conduct its own independent investigation of the financial condition and affairs of the Borrower and each other Loan Party in connection with the making and continuance of the
Loans and with the issuance of the Letters of Credit. Each Lender and each Issuer also acknowledges that it shall, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and other Loan Documents. Except for documents expressly required by any Loan Document to be transmitted by the
Administrative Agent to the Lenders or the Issuers, the Administrative Agent shall not have any duty or responsibility to provide any Lender or any Issuer with any credit or other information concerning the business, prospects, operations, property,
financial and other condition or creditworthiness of any Loan Party or any Affiliate of any Loan Party that may come into the possession of the Administrative Agent or any Affiliate thereof or any employee or agent of any of the foregoing.

  
 9.6 Indemnification. Each Lender agrees to indemnify
the Administrative Agent and each of its Affiliates, and each of their respective directors, officers, employees, agents and advisors (to the extent not reimbursed by the Borrower), from and against such Lender’s aggregate Ratable Portion of
any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses and disbursements (including fees, expenses and disbursements of financial and legal advisors) of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against, the Administrative Agent or any of its Affiliates, directors, officers, employees, agents and advisors in any way relating to or arising out of this Agreement or the other Loan Documents or any action
taken or omitted by the Administrative Agent under this Agreement or the other Loan Documents; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s or such Affiliate’s gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse the Administrative
Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including fees, expenses and disbursements of financial and legal advisors) incurred by the Administrative Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of its rights or responsibilities under, this Agreement or the other Loan Documents, to the extent
that the Administrative Agent is not reimbursed for such expenses by the Borrower or another Loan Party. 
  
 9.7 Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the
Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, selected from among the
Lenders. In either case, such appointment shall be subject to the prior written approval of the Borrower (which approval may not be unreasonably withheld and shall not be required upon the occurrence and during the continuance of an Event of
Default). Upon the acceptance of any appointment as Administrative Agent by a successor Administrative Agent, such successor Administrative Agent 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 under this Agreement and the other Loan Documents. Prior to any retiring Administrative Agent’s resignation hereunder as
Administrative Agent, the retiring Administrative Agent shall take such action as may be reasonably necessary to assign to the successor Administrative Agent its rights as Administrative Agent under the Loan Documents. After such resignation, the
retiring 
  

 57 

 Administrative Agent shall continue to have the benefit of this Section 9 as to any actions taken or omitted
to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents. 
  
 9.8 The Arrangers; the Syndication Agent; the Co-Documentation Agents. None of the Arrangers, the Syndication Agent or the Co-Documentation Agents,
in their respective capacities as such, shall have any duties or responsibilities, and shall incur no liability, under this Agreement and the other Loan Documents.

any other amendment, by the Required Lenders (or by the Administrative Agent with the consent of the Required Lenders) and the Borrower, and then any such waiver or consent shall be effective only in the specific instance and for the specific

of Initial Borrowing Conditions);

unless in writing and signed by the Administrative Agent in addition to the Lenders required above to take such action, affect the rights or duties of the Administrative Agent under this Agreement or the other Loan Documents; and provided,
further, that the Administrative Agent may, with the consent of the Borrower, amend, modify or supplement this Agreement to cure any ambiguity, omission, defect or inconsistency, so long as such amendment, modification or supplement does not

accordance with the terms of this Agreement without the consent of any Lender; and provided, further, that the Borrower and the Administrative Agent may enter into any amendment contemplated by Section 7.10 without the
consent of any Lender.

shall have no obligation to, with the written concurrence of any Lender, execute amendments, modifications, waivers or consents on behalf of such Lender. Any waiver or consent shall be effective only in the specific instance and for the specific
purpose for which it was given. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances. 
  
 10.2 Assignments and Participations. 
  
 (a) Each Lender may sell, transfer, negotiate or assign to one or more Eligible Assignees all or a portion of its rights and
obligations hereunder (including all of its rights and obligations with respect to the Revolving Loans and the Letters of Credit); provided, however, that (i) if any such assignment shall be of the assigning Lender’s
Revolving Credit Outstandings and Revolving Credit Commitments, such assignment shall cover the same percentage of such Lender’s Revolving Credit Outstandings and Revolving Credit Commitments, (ii) the aggregate amount being assigned
pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event (if less than the assignor’s entire interest) be less than $5,000,000 or an integral multiple of
$1,000,000 in excess thereof, except, in either case, (A) with the consent of the Borrower and the Administrative Agent or (B) if such assignment is being made to a Lender or an Affiliate or Approved Fund of such Lender, and (iii) if
such Eligible Assignee is not, prior to the date of such assignment, a Lender or an Affiliate or Approved Fund of a Lender, such assignment shall be subject to the prior consent of the Administrative Agent and the Borrower (which consents shall not
be unreasonably withheld or delayed); and provided, further, that, notwithstanding any other provision of this Section 10.2, the consent of the Borrower shall not be required for any assignment occurring when any Event of
Default shall have occurred and be continuing. 
  

 59 

 (b) The parties to each such assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment and Acceptance, together with any Revolving Credit Note (if the assigning Lender’s Revolving Loans are evidenced by a Revolving Credit Note) subject to such assignment. Upon the execution,
delivery, acceptance and recording in the Register of any Assignment and Acceptance and, other than in respect of assignments made pursuant to Section 2.16 (Substitution of Lenders), the receipt by the Administrative Agent from the
assignee of an assignment fee in the amount of $3,500 from and after the effective date specified in such Assignment and Acceptance, (i) the assignee thereunder shall become a party hereto and, to the extent that rights and obligations under
the Loan Documents have been assigned to such assignee pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender and, if such Lender were an Issuer, of such Issuer hereunder and thereunder, and (ii) the Revolving
Credit Notes (if any) corresponding to the Loans assigned thereby shall be transferred to such assignee by notation in the Register and (iii) the assignor thereunder shall, to the extent that rights and obligations under this Agreement have
been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights (except for those surviving the payment in full of the Obligations) and be released from its obligations under the Loan Documents, other than those relating to
events or circumstances occurring prior to such assignment (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under the Loan Documents, such Lender shall cease
to be a party hereto). 
  
 (c) The Administrative Agent shall
maintain at its address referred to in Section 10.8 (Notices, Etc.) a copy of each Assignment and Acceptance delivered to and accepted by it and shall record in the Register the names and addresses of the Lenders and Issuers and the
principal amount of the Revolving Loans or Reimbursement Obligation owing to each Lender from time to time and the Revolving Credit Commitments of each Lender. Any assignment pursuant to this Section 10.2 shall not be effective until

 (d) Upon its
receipt of an Assignment and Acceptance executed by an assigning Lender and an assignee, the Administrative Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record or cause
to be recorded the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower. Within five Business Days after its receipt of such notice, the Borrower, at its own expense, shall, if requested by such
assignee, execute and deliver to the Administrative Agent new Revolving Credit Notes to the order of such assignee in an amount equal to the Revolving Credit Commitments and Revolving Loans assumed by it pursuant to such Assignment and Acceptance
and, if the assigning Lender has surrendered any Revolving Credit Note for exchange in connection with the assignment and has retained Commitments or Revolving Loans hereunder, new Revolving Credit Notes to the order of the assigning Lender in an
amount equal to the Revolving Credit Commitments and Revolving Loans retained by it hereunder. Such new Revolving Credit Notes shall be dated the same date as the surrendered Revolving Credit Notes and be in substantially the form of Exhibit E
(Form of Revolving Credit Note). 
  
 (e) In addition to the
other assignment rights provided in this Section 10.2, each Lender may do each of the following: 
  
 (i) grant to a Special Purpose Vehicle the option to make all or any part of any Loan that such Lender would otherwise be required to make
hereunder and the exercise of such option by any such Special Purpose Vehicle and the making of Loans pursuant thereto shall satisfy (once and to the extent that such Revolving Loans are made) the obligation of such Lender to make such Revolving
Loans thereunder; provided, however, that (x) nothing herein shall constitute a commitment or an offer to commit by such a Special Purpose Vehicle to make Revolving Loans hereunder and no such Special Purpose Vehicle shall be
liable for any indemnity or other 
  

 60 

 Obligation (other than the making of Revolving Loans for which such Special Purpose Vehicle shall have
exercised an option, and then only in accordance with the relevant option agreement) and (y) such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain responsible to the other parties for the
performance of its obligations under the terms of this Agreement and shall remain the holder of the Obligations for all purposes hereunder; and 
  
 (ii) assign, as collateral or otherwise, any of its rights under this Agreement, whether now owned or hereafter acquired (including rights
to payments of principal or interest on the Revolving Loans), to (A) without notice to or consent of the Administrative Agent or the Borrower, any Federal Reserve Bank (pursuant to Regulation A of the Federal Reserve Board) and (B) without
consent of the Administrative Agent or the Borrower, (1) any holder of, or trustee for the benefit of, the holders of such Lender’s Securities and (2) any Special Purpose Vehicle to which such Lender has granted an option pursuant to
clause (i) above; 
  
 provided, however, that no such
assignment or grant shall release such Lender from any of its obligations hereunder except as expressly provided in clause (i) above. Each party hereto acknowledges and agrees that, prior to the date that is one year and one day after
the payment in full of all outstanding commercial paper or other senior debt of any such Special Purpose Vehicle, such party shall not institute against, or join any other Person in instituting against, any Special Purpose Vehicle that has been
granted an option pursuant to this clause (e) any bankruptcy, reorganization, insolvency or liquidation proceeding (such agreement shall survive the payment in full of the Obligations). The terms of the designation of, or assignment to,
such Special Purpose Vehicle shall not restrict such Lender’s ability to, or grant such Special Purpose Vehicle the right to, consent to any amendment or waiver to this Agreement or any other Loan Document or to the departure by the Borrower
from any provision of this Agreement or any other Loan Document without the consent of such Special Purpose Vehicle except, as long as the Administrative Agent, the Lenders and the Issuers shall continue to, and shall be entitled to continue to,
deal solely and directly with such Lender in connection with such Lender’s obligations under this Agreement, to the extent any such consent would reduce the principal amount of, or the rate of interest on, any Obligations, amend this clause
(e) or postpone any scheduled date of payment of such principal or interest. Each Special Purpose Vehicle shall be entitled to the benefits of Sections 2.14 (Capital Adequacy) and 2.15 (Taxes) as if it were such Lender;
provided, however, that anything herein to the contrary notwithstanding, no Borrower shall, at any time, be obligated to make under 2.14 (Capital Adequacy) or 2.15 (Taxes) to any such Special Purpose Vehicle and any such
Lender any payment in excess of the amount the Borrower would have been obligated to pay to such Lender in respect of such interest if such Special Purpose Vehicle had not been assigned the rights of such Lender hereunder; and provided,
further, that such Special Purpose Vehicle shall have no direct right to enforce any of the terms of this Agreement against the Borrower, the Administrative Agent or the other Lenders. 
  
 (f) Each Lender may sell participations to one or more Persons in or to all
or a portion of its rights and obligations under the Loan Documents (including all its rights and obligations with respect to the Revolving Loans and Letters of Credit). The terms of such participation shall not, in any event, require the
participant’s consent to any amendments, waivers or other modifications of any provision of any Loan Documents, the consent to any departure by any Loan Party therefrom, or to the exercising or refraining from exercising any powers or rights
such Lender may have under or in respect of the Loan Documents (including the right to enforce the obligations of the Loan Parties), except if any such amendment, waiver or other modification or consent would reduce the amount, or postpone any date
fixed for, any amount (whether of principal, interest or fees) payable to such participant under the Loan Documents, to which such participant would otherwise be entitled under such participation. In the event of the sale of any participation by any
Lender, (w) such Lender’s obligations under the Loan Documents shall remain unchanged, (x) such Lender shall remain solely responsible to the other parties for the 
  

 61 

 performance of such obligations, (y) such Lender shall remain the holder of such Obligations for all purposes of
this Agreement and (z) 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. Each participant
shall be entitled to the benefits of Sections 2.14 (Capital Adequacy) and 2.15 (Taxes) as if it were a Lender; provided, however, that anything herein to the contrary notwithstanding, the Borrower shall not, at any time, be
obligated to make under 2.14 (Capital Adequacy) or 2.15 (Taxes) to the participants in the rights and obligations of any Lender (together with such Lender) any payment in excess of the amount the Borrower would have been obligated to pay to
such Lender in respect of such interest had such participation not been sold and provided, further, that such participant in the rights and obligations of such Lender shall have no direct right to enforce any of the terms of this
Agreement against the Borrower, the Administrative Agent or the other Lenders. 
  
 (g) Any Issuer may at any time assign its rights and obligations hereunder to any other Lender by an instrument in form and substance satisfactory to the Borrower, the Administrative Agent, such Issuer and such
Lender, subject to the provisions of Section 2.6(c) (Evidence of Debt) relating to notations of transfer in the Register; provided, however, that each such assignment shall be subject to the prior consent of the Borrower (which
consent shall not be unreasonably withheld or delayed); and provided, further, that, notwithstanding the foregoing, the consent of the Borrower shall not be required for any assignment occurring when any Event of Default shall have
occurred and be continuing. If any Issuer ceases to be a Lender hereunder by virtue of any assignment made pursuant to this Section 10.2, then, as of the effective date of such cessation, such Issuer’s obligations to Issue Letters
of Credit pursuant to Section 2.3 (Letters of Credit) shall terminate and such Issuer shall be an Issuer hereunder only with respect to outstanding Letters of Credit issued prior to such date. 
  
 10.3 Costs and Expenses. 
  
 (a) The Borrower agrees upon demand to pay, or reimburse the Administrative
Agent for, all of the Administrative Agent’s reasonable internal and external audit, legal, appraisal, valuation, filing, document duplication and reproduction and investigation expenses and for all other reasonable out-of-pocket costs and
expenses of every type and nature (including the reasonable fees, expenses and disbursements of the Administrative Agent’s counsel, Weil, Gotshal & Manges LLP, local legal counsel, auditors, accountants, appraisers, printers, insurance

connection with the preparation, negotiation or execution of any Loan Document or the Administrative Agent’s periodic audits of the Borrower or any of its Subsidiaries, as the case may be, (ii) the preparation, negotiation, execution or
interpretation of this Agreement (including, without limitation, the satisfaction or attempted satisfaction of any condition set forth in Section 4 (Conditions Precedent)), any Loan Document or any proposal letter or commitment letter
issued in connection therewith, or the making of the Loans hereunder, (iii) the ongoing administration of this Agreement and the Loans, including consultation with attorneys in connection therewith and with respect to the Administrative
Agent’s rights and responsibilities hereunder and under the other Loan Documents, (iv) the protection, collection or enforcement of any Obligation or the enforcement of any Loan Document, (v) the commencement, defense or intervention
in any court proceeding relating in any way to the Obligations, any Loan Party, any of the Borrower’s Subsidiaries, this Agreement or any other Loan Document, (vi) the response to, and preparation for, any subpoena or request for document
production with which the Administrative Agent is served or deposition or other proceeding in which the Administrative Agent is called to testify, in each case, relating in any way to the Obligations, any Loan Party, any of the Borrower’s
Subsidiaries, this Agreement or any other Loan Document or (vii) any amendment, consent, waiver, assignment, restatement, or supplement to any Loan Document or the preparation, negotiation and execution of the same; provided,
however, that the Borrower shall not have any liability under subclauses (v) and (vi) of 
  

 62 

 this Section 10.3(a) with respect to any costs and expenses that has resulted from the gross negligence or
willful misconduct of the Administrative Agent or the breach by the Administrative Agent of its obligations under this Agreement, as determined by a court of competent jurisdiction in a final non-appealable judgment or order. 
  
 (b) The Borrower further agrees to pay or reimburse the Administrative Agent
and each of the Lenders and Issuers upon demand for all out-of-pocket costs and expenses, including reasonable attorneys’ fees (including allocated costs of internal counsel and costs of settlement), incurred by the Administrative Agent, such
Lenders or such Issuers in connection with any of the following: (i) in enforcing any Loan Document or Obligation or exercising or enforcing any other right or remedy available by reason of an Event of Default, (ii) in connection with any
refinancing or restructuring of the credit arrangements provided hereunder in the nature of a “work-out” or in any insolvency or bankruptcy proceeding, (iii) in commencing, defending or intervening in any litigation or in
filing a petition, complaint, answer, motion or other pleadings in any legal proceeding relating to the Obligations, any Loan Party, any of the Borrower’s Subsidiaries and related to or arising out of the transactions contemplated hereby or by
any other Loan Document or (iv) in taking any other action in or with respect to any suit or proceeding (bankruptcy or otherwise) described in clause (i), (ii) or (iii) above; provided, however,
that the Borrower shall not have any liability under clause (iii) of this Section 10.3(b) to the Administrative Agent, any Lender or any Issuer with respect to any costs and expenses that has resulted from the gross
negligence or willful misconduct of the Administrative Agent, such Lender or such Issuer, as applicable, or the breach by the Administrative Agent, such Lender or such Issuer, as applicable, of its obligations under this Agreement, as determined by
a court of competent jurisdiction in a final non-appealable judgment or order. 
  
 10.4 Indemnities. 
  
 (a)
The Borrower agrees to indemnify and hold harmless each Agent, each Arranger, each Lender, each Issuer and each of their respective Affiliates, and each of the directors, officers, employees, agents, trustees, representatives, attorneys, consultants
and advisors of or to any of the foregoing (including those retained in connection with the satisfaction or attempted satisfaction of any condition set forth in Section 4 (Conditions Precedent)) (each such Person being an
“Indemnitee”) from and against any and all claims, damages, liabilities, obligations, losses, penalties, actions, judgments, suits, costs, disbursements and expenses, joint or several, of any kind or nature (including fees,
disbursements and expenses of financial and legal advisors to any such Indemnitee) that may be imposed on, incurred by or asserted against any such Indemnitee in connection with or arising out of any investigation, litigation or proceeding, whether
or not such investigation, litigation or proceeding is brought by any such Indemnitee or any of its directors, security holders or creditors or any such Indemnitee, director, security holder or creditor is a party thereto, whether direct, indirect,
or consequential and whether based on any federal, state or local law or other statutory regulation, securities or commercial law or regulation, or under common law or in equity, or on contract, tort or otherwise, in any manner relating to or
arising out of this Agreement, any other Loan Document, any Obligation, any Letter of Credit, or any act, event or transaction related or attendant to any thereof, or the use or intended use of the proceeds of the Revolving Loans or Letters of
Credit or in connection with any investigation of any potential matter covered hereby (collectively, the “Indemnified Matters”); provided, however, that the Borrower shall not have any liability under this
Section 10.4 to an Indemnitee with respect to any Indemnified Matter that has resulted from the gross negligence or willful misconduct of such Indemnitee or the breach by such Indemnitee of its obligations under this Agreement, as
determined by a court of competent jurisdiction in a final non-appealable judgment or order. 
  
 (b) The Borrower shall indemnify each Agent, each Arranger, each Lender and each Issuer for, and hold the Agents, the Arrangers, the Lenders and the Issuers harmless from and against, any 
  

 63 

 and all claims for brokerage commissions, fees and other compensation made against the Agents, the Arrangers, the Lenders
and the Issuers for any broker, finder or consultant with respect to any agreement, arrangement or understanding made by or on behalf of any Loan Party or any of the Borrower’s Subsidiaries in connection with the transactions contemplated by
this Agreement. 
  
 (c) The Borrower, at the request of any
Indemnitee, shall have the obligation to defend against any investigation, litigation or proceeding, in each case contemplated in clause (a) above, and the Borrower, in any event, may participate in the defense thereof with legal counsel
of the Borrower’s choice. In the event that such indemnitee requests the Borrower to defend against such investigation, litigation or proceeding, the Borrower shall promptly do so and such Indemnitee shall have the right to have legal counsel
of its choice participate in such defense. No action taken by legal counsel chosen by such Indemnitee in defending against any such investigation, litigation or proceeding shall vitiate or in any way impair the Borrower’s obligation and duty
hereunder to indemnify and hold harmless such Indemnitee. 
  
 (d)
The Borrower agrees that any indemnification or other protection provided to any Indemnitee pursuant to this Agreement (including pursuant to this Section 10.4) or any other Loan Document shall (i) survive payment in full of the
Obligations and (ii) inure to the benefit of any Person that was at any time an Indemnitee under this Agreement or any other Loan Document. 
  
 10.5 Limitation of Liability. 
  
 (a) The Borrower agrees that no Indemnitee shall have any liability (whether in contract, tort or otherwise) to any Loan Party or any of their respective
Subsidiaries or any of their respective equity holders or creditors for or in connection with the transactions contemplated hereby and in the other Loan Documents, except to the extent such liability is determined in a final non-appealable judgment
by a court of competent jurisdiction to have resulted from such Indemnitee’s gross negligence or willful misconduct or the breach by such Indemnitee of its obligations under this Agreement. In no event, however, shall any Indemnitee be liable
on any theory of liability for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings). The Borrower hereby waives, releases and agrees (each for itself and on
behalf of its Subsidiaries and the MLP) not to sue upon any such claim for any special, indirect, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor. 
  
 (b) IN NO EVENT SHALL ANY AGENT AFFILIATE HAVE ANY LIABILITY TO ANY LOAN
PARTY, LENDER, ISSUER OR ANY OTHER PERSON FOR DAMAGES OF ANY KIND, INCLUDING DIRECT OR INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT OR CONTRACT OR OTHERWISE) ARISING OUT OF ANY LOAN PARTY OR ANY AGENT
AFFILIATE’S TRANSMISSION OF APPROVED ELECTRONIC COMMUNICATIONS THROUGH THE INTERNET OR ANY USE OF THE APPROVED ELECTRONIC PLATFORM, EXCEPT TO THE EXTENT SUCH LIABILITY OF ANY AGENT AFFILIATE IS FOUND IN A FINAL NON-APPEALABLE JUDGMENT BY A
COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FORM SUCH AGENT AFFILIATE’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. 
  
 10.6 Right of Set-off. Upon the occurrence and during the continuance of any Event of Default each Lender and each Affiliate of a Lender is hereby
authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness at any time owing by
such Lender or its Affiliates to or for the credit or the account of the Borrower against any and all of the Obligations now or hereafter existing whether or not such Lender shall have made any demand under this 
  

 64 

 Agreement or any other Loan Document and even though such Obligations may be unmatured. Each Lender agrees promptly to
notify the Borrower after any such set-off and application made by such Lender or its Affiliates; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each
Lender under this Section 10.6 are in addition to the other rights and remedies (including other rights of set-off) that such Lender may have. 
  
 10.7 Sharing of Payments, Etc. 
  
 (a) If any Lender (directly or through an Affiliate thereof) obtains any payment (whether voluntary, involuntary, through the exercise of any right of
set-off (including pursuant to Section 10.6 (Right of Set-off)) or otherwise) of the Loans owing to it, any interest thereon, fees in respect thereof or amounts due pursuant to Section 10.3 (Costs and Expenses) or 10.4
Indemnities) (other than payments pursuant to Section 2.13 (Special Provisions Governing Eurodollar Rate Loans), 2.14 (Capital Adequacy) or 2.15 (Taxes) (in each case, whether voluntary, involuntary, through the
exercise of any right of set-off (including pursuant to Section 10.6 (Right of Set-off)) or otherwise) in excess of its Ratable Portion of all payments of such Obligations obtained by all the Lenders, such Lender (a “Purchasing
Lender”) shall forthwith purchase from the other Lenders (each, a “Selling Lender”) such participations in their Loans or other Obligations as shall be necessary to cause such Purchasing Lender to share the excess payment
ratably with each of them. 
  
 (b) If all or any portion of any
payment received by a Purchasing Lender is thereafter recovered from such Purchasing Lender, such purchase from each Selling Lender shall be rescinded and such Selling Lender shall repay to the Purchasing Lender the purchase price to the extent of
such recovery together with an amount equal to such Selling Lender’s ratable share (according to the proportion of (i) the amount of such Selling Lender’s required repayment in relation to (ii) the total amount so recovered from
the Purchasing Lender) of any interest or other amount paid or payable by the Purchasing Lender in respect of the total amount so recovered. 
  
 (c) The Borrower agrees that any Purchasing Lender so purchasing a participation from a Selling Lender pursuant to this Section 10.7 may, to
the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

 WHEREAS, it is
provided in the Indenture that all the business, franchises and properties, real, personal, and mixed, of every kind and nature whatsoever and wheresoever situated, which might thereafter be acquired by the Corporation, shall be as fully embraced
within the lien thereof as if said properties were owned by the Corporation at the date of the Base Indenture and were particularly described therein and specifically conveyed thereby, excepting certain properties expressly excepted by the
provisions of the Indenture; and 
  
 WHEREAS, subsequent to the
execution of the most recently recorded Prior Supplemental Indenture identifying after acquired property, the Corporation has acquired properties hereinafter mentioned or referred to, all of which properties, upon the acquisition thereof by the
Corporation, became and now are subject to the lien, operation and effect of the Indenture by virtue of the after-acquired property clause or other clauses thereof; the Corporation, nevertheless, desires to execute, acknowledge, deliver and cause to

“Exchange Act”), designated to act as depositary (a “depositary”) for such Global Securities.

 Section 1.03. In the event the Series KK Bonds are issued as a Global Security the following provisions,
in addition to the provisions of the Indenture, shall apply: 
  
 (a) Each Global Security authenticated under the Indenture shall be registered in the name of the depositary designated for such Global Security or a nominee thereof and delivered to such depositary or a nominee
thereof or custodian therefor, and each such Global Security shall constitute a single bond for all purposes of this Supplemental Indenture. 
  
 (b) Notwithstanding any other provision in this Supplemental Indenture, no Global Security may be exchanged in whole or in part for bonds
registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any person other than the depositary for such Global Security or a nominee thereof unless (A) such depositary has notified the Corporation
that it is unwilling or unable to continue as depositary for such Global Security and a successor depositary has not been appointed by the Corporation within 90 days of receipt by the Corporation of such notification, (B) if at any time the
depositary ceases to be a clearing agency registered under the Exchange Act at a time when the depositary is required to be so registered to act as such depositary and no successor depositary shall have been appointed by the Corporation within 90
days after it became aware of such cessation, (C) the Corporation, in its sole discretion, executes and delivers to the Trustee a written order signed in the name of the Corporation by its Chairman of the Board, its President or a Vice
President, and by its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary to the effect that such Global Security, together with all other Global Securities of the same series, shall be exchangeable as described below, or
(D) an Event of Default (as defined in Section 1.02 of the Indenture) has occurred and is continuing with respect to the Series KK Bonds. If any of the events described in clauses (A) through (D) of the preceding sentence occur,
the beneficial owners of interests in the relevant Global Securities will be entitled to exchange those interests for definitive bonds and, without unnecessary delay but in any event not later than the earliest date on which those interests may be
so exchanged, the Corporation will deliver to the Trustee definitive bonds in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in an aggregate principal amount equal
to the principal amount of such Global Securities, such bonds to be duly executed by the Corporation. On or after the earliest date on which such beneficial interests may be so exchanged, such Global Securities shall be surrendered from time to time
by the depositary as shall be specified in the order from the Corporation with respect thereto (which the Corporation agrees to deliver), and in accordance with any instructions given to the Trustee and the depositary (which instructions shall be in
writing but need not be contained in or accompanied by an officers’ certificate or be accompanied by an opinion of counsel), as shall be specified in the order from the Corporation with respect thereto to the Trustee, as the Corporation’s
agent for such purpose, to be exchanged, in whole or in part, for definitive bonds as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered Global Security, a
like aggregate principal amount of definitive bonds of the same series of authorized denominations and of like tenor as the portion of such Global Security to be exchanged. Promptly following any such exchange in part, such Global Security shall be
returned by the Trustee to such depositary or its custodian. If a definitive bond is issued in exchange for any portion of a Global Security after the close of business at the place where such exchange occurs on or after (i) any regular record
date for the date the interest is due (the “Interest Payment Date”) 

  

 6 

 
for such bond and before the opening of business at that place of payment on the next Interest Payment Date, or (ii) any special record date for the
payment of interest for such bond and before the opening of business at such place of payment on the related proposed date for the payment of the interest which was not punctually paid or duly provided for on any Interest Payment Date
(“Defaulted Interest”), as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such definitive bond, but shall be payable on the Interest
Payment Date or proposed date for payment, as the case may be, only to the person to whom interest in respect of such portion of such Global Security shall be payable in accordance with the provisions of this Indenture. 
  
 (c) Subject to Clause (b) above, any exchange or
transfer of a Global Security for other bonds may be made in whole or in part, and all bonds issued in exchange for or upon transfer of a Global Security or any portion thereof shall be registered in such names as the depositary for such Global
Security shall direct. 
  
 (d) Every bond
authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such bond is
registered in the name of a person other than the depositary for such Global Security or a nominee thereof. 
  
 Section 1.04. Unless otherwise specified as contemplated by Section 2.01 for the bonds evidenced thereby, every Global Security authenticated and
delivered hereunder shall bear a legend in substantially the following form: 
  
 THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART
FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE. ANY
TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN. 
  
 Section 1.05. The fully registered bonds without coupons and the certificate of authentication to be endorsed on all Series KK Bonds shall be
substantially in the form set forth on Exhibit A. 
  
 Section
1.06. The Series KK Bonds may contain or have imprinted thereon such provisions or specifications not inconsistent with the Indenture as may be required to comply with the rules of any stock exchange or any federal or state authority or commission,

determine. 
  
 Section 1.08. In the manner and subject to certain
conditions and limitations specified herein and in the Indenture, Series KK Bonds may be exchanged without a service charge for a like aggregate principal amount of such Series KK Bonds of other authorized denomination or denominations; provided
that the Corporation may require payment of a sum or sums sufficient to reimburse it for any stamp tax or other governmental charge payable in connection therewith. 
  
 Section 1.09. The Corporation shall maintain in the City and County of San Francisco, State of California, and in such other
place or places as the Corporation may designate at any time or from time to time, an office or agency where Series KK Bonds may be presented for payment, registration, transfer and exchange as provided therein or in the Indenture. Such office or
agency in the City and County of San Francisco shall be the corporate trust office of the Trustee unless and until the Corporation shall designate another office or agency by notice in writing delivered to the Trustee. Notwithstanding the foregoing,
if and when definitive bonds are issued, the Corporation shall maintain in the Borough of Manhattan, City and County of New York, State of New York, an office or agency where Series KK Bonds may be presented for payment, registration, transfer and
exchange as provided therein or in the Indenture. 
  
 Section
1.10. No transfer or exchange of any Series KK Bonds pursuant to any of the provisions of this Article I shall be made except upon and in accordance with all of the applicable terms, provisions and conditions of said bonds and of the Indenture.

“Indenture”), reference is hereby made for a description of the property conveyed in trust, mortgaged and pledged, the nature and extent of the security, the rights of the registered owners of the bonds and of the Trustee or
trustees in respect thereof, the terms and conditions upon which the bonds are, and are to be, secured and the circumstances under which additional bonds may be issued. The bonds may be issued for various principal sums, and may be issued in series,
which may mature at different times, may bear interest at different times, may bear interest at different rates and may otherwise vary as in the Indenture provided. This bond is one of a series designated as the “First Mortgage Bonds, Series
KK, due 2035” (herein called “Series KK Bonds”) of the Corporation, issued under and secured by the Indenture. Terms used but not defined herein shall have the respective meanings assigned thereto in the Indenture. 

 
 As provided in the Indenture, by any indenture or indentures supplemental
thereto executed by the Corporation and the Trustee and consented to by the holders of not less than two-thirds ( 2/3) in principal amount of the bonds at the time outstanding, and, in case one or more, but less than all, of the series of bonds then outstanding are affected by such supplemental indenture, consented to by the holders of at least
two-thirds ( 2/3) in principal amount of the bonds of each series so affected, the Indenture or any indenture
supplemental thereto and the rights and obligations of the Corporation and the holders of bonds, may be modified or altered from time to time, as provided in the Indenture; provided, however, (a) that the right of any holder of any bond to

Series KK Bonds are entitled to the benefits of the Renewal Fund as provided in the Indenture.

 The price at which the Series KK Bonds will be redeemed (the “Redemption Price”) on the date fixed for such redemption (the
“Redemption Date”) will be equal to the greater of the 

 
following amounts: (a) 100% of the principal amount of the bonds being redeemed on the Redemption Date; or (b) the sum of the present values of the
remaining scheduled payments of principal and interest on the Series KK Bonds being redeemed on that Redemption Date (not including any portion of any payments of accrued and unpaid interest to the Redemption Date) discounted to the Redemption Date
on a semiannual basis at the Adjusted Treasury Rate (as defined below) plus 20 basis points, as determined by the Reference Treasury Dealer (as defined below), plus, in each case, accrued and unpaid interest thereon to the Redemption Date.
Notwithstanding the foregoing, installments of interest on Series KK Bonds that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on such Interest Payment Dates to the registered holders of such
Series KK Bonds as of the close of business on the relevant record date. The Redemption Price will be calculated on the basis of a 360-day year consisting of twelve 30-day months. 
  
 Unless the Corporation defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to
accrue on the Series KK Bonds or portions thereof called for redemption. 
  
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. 
  
 “Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as having a maturity
comparable to the remaining term of the Series KK Bonds to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to
the remaining term of such Series KK Bonds. 
  
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the average of the Reference Treasury Dealer Quotations for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation
is received, such Quotation. 
  
 “Reference Treasury
Dealer” means (A) LaSalle Financial Services, Inc. (or its affiliates which are Primary Treasury Dealers) and its successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer
in New York City (a “Primary Treasury Dealer”), the Corporation will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Corporation. 
  
 “Reference Treasury Dealer Quotation” means, with respect to
each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Corporation, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing
to the Corporation by such Reference Treasury Dealer at 5:00 p.m. (New York City time) on the third business day preceding such Redemption Date. 
  
 In the event of redemption of this bond in part only, a new bond or Series KK Bonds of like tenor for the unredeemed portion hereof will be issued in the
name of the holder hereof upon the cancellation hereof. 

 Notice of any such redemption will be mailed to the registered owners of the Series KK Bonds to be
redeemed not less than 30 nor more than 60 days before the Redemption Date. Once notice of redemption is mailed, the Series KK Bonds called for redemption will become due and payable on the Redemption Date and at the applicable redemption price,
plus accrued and unpaid interest to the Redemption Date. Upon the Corporation’s election to redeem all or a portion of the Series KK Bonds, that redemption will not be conditional upon receipt by the paying agent or the Trustee of monies
sufficient to pay the Redemption Price. 
  
 In case an event of
default, as defined in the Indenture, shall occur, the principal of all bonds then outstanding under the Indenture may be declared or become due and payable upon the conditions and in the manner and with the effect provided in the Indenture.

  
 This bond is transferable by the registered owner hereof at
the office or agency of the Corporation in said City and County of San Francisco [if this bond is a definitive bond, insert: “, or at the office or agency in the Borough of Manhattan, City and County of New York, State of New York, that the
Corporation maintains for such purpose”] and in such other place or places as the Corporation may designate at any time or from time to time, and thereupon a new fully registered bond or bonds of said series, without coupons, of authorized
denomination or denominations, of a like aggregate principal amount, will be issued to the transferee or transferees in exchange for this bond; and at any of said offices or agencies fully registered Series KK Bonds without coupons, are exchangeable
for a like aggregate principal amount of other such fully registered bonds of authorized denominations; all in the manner and subject to the conditions as provided in the Indenture. 
  
 No recourse shall be had for the payment of the principal of or the interest on this bond or for any claim based hereon or
on the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, director or officer, past, present or future, of the Corporation, or of any predecessor or successor corporation, either directly or through the
Corporation, or any such predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty, or otherwise, all such liability being waived and released by every
registered owner hereof by the acceptance of this bond and as part of the consideration for the issue hereof, and being likewise waived and released by the terms of the Indenture. 
  
 This bond shall not become valid or obligatory for any purpose or be entitled to any benefit under the Indenture until U.S.
Bank National Association, or its successor as Trustee under the Indenture, shall have signed the form of certificate endorsed hereon. 
  
 This bond shall be governed by and construed in accordance with the laws of the State of California, without regard to conflicts of laws principles
thereof.
