 AMOUNT AND TERMS OF THE COMMITMENTS 
 Section 2.1. General Description of Facilities. Subject to and upon the terms and conditions herein set forth, (i) the Lenders hereby establish in favor of the Borrower a revolving
credit facility pursuant to which each Lender severally agrees (to the extent of such Lender’s Revolving Commitment) to make Revolving Loans to the Borrower in accordance with Section 2.2, (ii) the Issuing Bank agrees to issue Letters
of Credit in accordance with Section 2.20, (iii) the Swingline Lender agrees to make Swingline Loans in accordance with Section 2.4 and (iv) each Lender agrees to purchase a participation interest in the Letters of Credit and the
Swingline Loans pursuant to the terms and conditions hereof; provided, that in no event shall the aggregate principal amount of all outstanding Revolving Loans, Swingline Loans and outstanding LC Exposure exceed at any time the Aggregate Revolving
Commitment Amount from time to time in effect. 
 Section 2.2. Revolving Loans. Subject to the terms and conditions
set forth herein, each Lender severally agrees to make Revolving Loans, ratably in proportion to its Pro Rata Share, to the Borrower, from time to time during the Availability Period, in an aggregate principal amount outstanding at any time that
will not result in such Lender’s Revolving Credit Exposure exceeding such Lender’s Revolving Commitment. During the Availability Period, the Borrower shall be entitled to borrow, prepay and reborrow Revolving Loans in accordance with the
terms and conditions of this Agreement; provided, that the Borrower may not borrow or reborrow should there exist a Default or Event of Default. 
 Section 2.3. Procedure for Revolving Borrowings. The Borrower shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of each Revolving Borrowing substantially in the
form of Exhibit 2.3 (a “Notice of Revolving Borrowing”) (x) prior to 11:00 a.m. (New York time) on the requested date of each Base Rate Borrowing and (y) prior to 11:00 a.m. (New York time) three (3) Business
Days prior to the requested date of each Eurodollar Borrowing. Each Notice of Revolving Borrowing shall be irrevocable and shall specify: (i) the aggregate principal amount of such Borrowing, (ii) the date of such Borrowing (which shall be
a Business Day), (iii) the Type of such Revolving Loan 

  

 27 

 
comprising such Borrowing and (iv) in the case of a Eurodollar Borrowing, the duration of the initial Interest Period applicable thereto (subject to the
provisions of the definition of Interest Period). Each Revolving Borrowing shall consist entirely of Base Rate Loans or Eurodollar Loans, as the Borrower may request. The aggregate principal amount of each Borrowing shall be not less than $5,000,000
or a larger multiple of $1,000,000; provided, that Base Rate Loans made pursuant to Section 2.4 or Section 2.20(d) may be made in lesser amounts as provided therein. At no time shall the total number of Eurodollar Borrowings
outstanding at any time exceed five. Promptly following the receipt of a Notice of Revolving Borrowing in accordance herewith, the Administrative Agent shall advise each Lender of the details thereof and the amount of such Lender’s Revolving
Loan to be made as part of the requested Revolving Borrowing. 
 Section 2.4. Swingline Commitment. 
 (a) Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Borrower, from time to time during
the Availability Period, in an aggregate principal amount outstanding at any time not to exceed the lesser of (i) the Swingline Commitment then in effect and (ii) the difference between the Aggregate Revolving Commitment Amount and the
aggregate Revolving Credit Exposures of all Lenders; provided, that the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. The Borrower shall be entitled to borrow, repay and reborrow
Swingline Loans in accordance with the terms and conditions of this Agreement. 
 (b) The Borrower shall give the Administrative Agent
written notice (or telephonic notice promptly confirmed in writing) of each Swingline Borrowing substantially in the form of Exhibit 2.4 attached hereto (“Notice of Swingline Borrowing”) prior to 11:00 a.m. (New York time) on
the requested date of each Swingline Borrowing. Each Notice of Swingline Borrowing shall be irrevocable and shall specify: (i) the principal amount of such Swingline Loan, (ii) the date of such Swingline Loan (which shall be a Business
Day) and (iii) the account of the Borrower to which the proceeds of such Swingline Loan should be credited. The Administrative Agent will promptly advise the Swingline Lender of each Notice of Swingline Borrowing. Each Swingline Loan shall
accrue interest at the Base Rate or any other interest rate as agreed between the Borrower and the Swingline Lender and shall have an Interest Period (subject to the definition thereof) as agreed between the Borrower and the Swingline Lender. The
aggregate principal amount of each Swingline Loan shall be not less than $100,000 or a larger multiple of $50,000, or such other minimum amounts agreed to by the Swingline Lender and the Borrower. The Swingline Lender will make the proceeds of each
Swingline Loan available to the Borrower in Dollars in immediately available funds at the account specified by the Borrower in the applicable Notice of Swingline Borrowing not later than 1:00 p.m. (New York time) on the requested date of such
Swingline Loan. 
 (c) The Swingline Lender, at any time and from time to time in its sole discretion, may, on behalf of the Borrower (which
hereby irrevocably authorizes and directs the Swingline Lender to act on its behalf), give a Notice of Revolving Borrowing to the Administrative Agent requesting the Lenders (including the Swingline Lender) to make Base Rate Loans in an amount equal
to the unpaid principal amount of any Swingline Loan. Each Lender will make the proceeds of its Base Rate Loan included in such Borrowing available to the 
  

 28 

 
Administrative Agent for the account of the Swingline Lender in accordance with Section 2.5, which will be used solely for the repayment of such
Swingline Loan. 
 (d) If for any reason a Base Rate Borrowing may not be (as determined in the sole discretion of the Administrative Agent),
or is not, made in accordance with the foregoing provisions, then each Lender (other than the Swingline Lender) shall purchase an undivided participating interest in such Swingline Loan in an amount equal to its Pro Rata Share thereof on the date
that such Base Rate Borrowing should have occurred. On the date of such required purchase, each Lender shall promptly transfer, in immediately available funds, the amount of its participating interest to the Administrative Agent for the account of
the Swingline Lender. If such Swingline Loan bears interest at a rate other than the Base Rate, such Swingline Loan shall automatically become a Base Rate Loan on the effective date of any such participation and interest shall become payable on
demand. 
 (e) Each Lender’s obligation to make a Base Rate Loan pursuant to Section 2.4(c) or to purchase the participating
interests pursuant to Section 2.4(d) shall be absolute and unconditional and shall not be affected by any circumstance, including without limitation (i) any setoff, counterclaim, recoupment, defense or other right that such Lender
or any other Person may have or claim against the Swingline Lender, the Borrower or any other Person for any reason whatsoever, (ii) the existence of a Default or an Event of Default or the termination of any Lender’s Revolving Commitment,
(iii) the existence (or alleged existence) of any event or condition which has had or could reasonably be expected to have a Material Adverse Effect, (iv) any breach of this Agreement or any other Loan Document by the Borrower, the
Administrative Agent or any Lender or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If such amount is not in fact made available to the Swingline Lender by any Lender, the Swingline
Lender shall be entitled to recover such amount on demand from such Lender, together with accrued interest thereon for each day from the date of demand thereof (i) at the Federal Funds Rate until the second Business Day after such demand and
(ii) at the Base Rate at all times thereafter. Until such time as such Lender makes its required payment, the Swingline Lender shall be deemed to continue to have outstanding Swingline Loans in the amount of the unpaid participation for all
purposes of the Loan Documents. In addition, such Lender shall be deemed to have assigned any and all payments made of principal and interest on its Loans and any other amounts due to it hereunder, to the Swingline Lender to fund the amount of such
Lender’s participation interest in such Swingline Loans that such Lender failed to fund pursuant to this Section 2.4, until such amount has been purchased in full. 
 Section 2.5. Funding of Borrowings. 
 (a) Each Lender will make available each Loan to be made by it hereunder on the proposed date thereof by wire transfer in immediately available funds by 1:00 p.m. (New York time) to the Administrative Agent at the
Payment Office; provided, that the Swingline Loans will be made as set forth in Section 2.4. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts that it receives, in like funds
by the close of business on such proposed date, to an account maintained by the Borrower with the Administrative Agent or at the Borrower’s option, by effecting a wire transfer of such amounts to an account designated by the Borrower to the
Administrative Agent. 
  

 29 

 (b) Unless the Administrative Agent shall have been notified by any Lender (x) prior to 12:00 p.m.
(New York time) on the requested date of a Base Rate Borrowing and (y) prior to 5:00 p.m. (New York time) one (1) Business Day prior to the date of a Eurodollar Borrowing in which such Lender is to participate that such Lender will not
make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date, and the Administrative Agent, in
reliance on such assumption, may make available to the Borrower on such date a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender on the date of such Borrowing, the
Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender together with interest at the Federal Funds Rate until the second Business Day after such demand and thereafter at the Base Rate. If such Lender
does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the
Administrative Agent together with interest at the rate specified for such Borrowing. Nothing in this subsection shall be deemed to relieve any Lender from its obligation to fund its Pro Rata Share of any Borrowing hereunder or to prejudice any
rights which the Borrower may have against any Lender as a result of any default by such Lender hereunder. 
 (c) All Revolving Borrowings
shall be made by the Lenders on the basis of their respective Pro Rata Shares. No Lender shall be responsible for any default by any other Lender in its obligations hereunder, and each Lender shall be obligated to make its Loans provided to be made
by it hereunder, regardless of the failure of any other Lender to make its Loans hereunder. 
 Section 2.6. Interest
Elections. 
 (a) Each Borrowing initially shall be of the Type specified in the applicable Notice of Borrowing, and in the case of a
Eurodollar Borrowing, shall have an initial Interest Period as specified in such Notice of Borrowing. Thereafter, the Borrower may elect to convert such Borrowing into a different Type or to continue such Borrowing, and in the case of a Eurodollar
Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.6. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be
allocated ratably among the Lenders holding Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall NOT apply to Swingline Borrowings, which may not be converted or
continued. 
 (b) To make an election pursuant to this Section 2.6, the Borrower shall give the Administrative Agent prior
written notice (or telephonic notice promptly confirmed in writing) of each Borrowing substantially in the form of Exhibit 2.6 attached hereto (a “Notice of Conversion/Continuation”) that is to be converted or continued, as
the case may be, (x) prior to 11:00 a.m. (New York time) on the requested date of a conversion into a Base Rate Borrowing and (y) prior to 11:00 a.m. (New York time) three (3) Business Days prior to a continuation of or conversion
into a Eurodollar Borrowing. Each such Notice of Conversion/Continuation shall be irrevocable and shall specify (i) the Borrowing to which such Notice of Continuation/Conversion applies and if different options are being elected with respect to
different portions thereof, the 

  

 30 

 
portions thereof that are to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and
(iv) shall be specified for each resulting Borrowing); (ii) the effective date of the election made pursuant to such Notice of Continuation/Conversion, which shall be a Business Day, (iii) whether the resulting Borrowing is to be a
Base Rate Borrowing or a Eurodollar Borrowing; and (iv) if the resulting Borrowing is to be a Eurodollar Borrowing, the Interest Period applicable thereto after giving effect to such election, which shall be a period contemplated by the
definition of “Interest Period”. If any such Notice of Continuation/Conversion requests a Eurodollar Borrowing but does not specify an Interest Period, the Borrower shall be deemed to have selected an Interest Period of one month. The
principal amount of any resulting Borrowing shall satisfy the minimum borrowing amount for Eurodollar Borrowings and Base Rate Borrowings set forth in Section 2.3. 
 (c) If, on the expiration of any Interest Period in respect of any Eurodollar Borrowing, the Borrower shall have failed to deliver a Notice of
Conversion/Continuation, then, unless such Borrowing is repaid as provided herein, the Borrower shall be deemed to have elected to convert such Borrowing to a Base Rate Borrowing. No Borrowing may be converted into, or continued as, a Eurodollar
Borrowing if a Default or an Event of Default exists, unless the Administrative Agent and each of the Lenders shall have otherwise consented in writing. No conversion of any Eurodollar Loans shall be permitted except on the last day of the Interest
Period in respect thereof. 
 (d) Upon receipt of any Notice of Conversion/Continuation, the Administrative Agent shall promptly notify each
Lender of the details thereof and of such Lender’s portion of each resulting Borrowing. 
 Section 2.7. Optional
Reduction and Termination of Commitments. 
 (a) Unless previously terminated, all Revolving Commitments, Swingline Commitments and LC
Commitments shall terminate on the Revolving Commitment Termination Date. 
 (b) Upon at least three (3) Business Days’ prior
written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent (which notice shall be irrevocable), the Borrower may reduce the Aggregate Revolving Commitments in part or terminate the Aggregate Revolving Commitments
in whole; provided, that (i) any partial reduction shall apply to reduce proportionately and permanently the Revolving Commitment of each Lender, (ii) any partial reduction pursuant to this Section 2.7 shall be in an
amount of at least $5,000,000 and any larger multiple of $1,000,000, and (iii) no such reduction shall be permitted which would reduce the Aggregate Revolving Commitment Amount to an amount less than the outstanding Revolving Credit Exposures
of all Lenders. Any such reduction in the Aggregate Revolving Commitment Amount below the sum of the principal amount of the Swingline Commitment and the LC Commitment shall result in a proportionate reduction (rounded to the next lowest integral
multiple of $100,000) in the Swingline Commitment and the LC Commitment. 
  

 31 

 Section 2.8. Repayment of Loans. 
 (a) The outstanding principal amount of all Revolving Loans shall be due and payable (together with accrued and unpaid interest thereon) on the Revolving
Commitment Termination Date.

unpaid interest thereon) on the earlier of (i) the last day of the Interest Period applicable to such Borrowing and (ii) the Revolving Commitment Termination Date. 
 Section 2.9. Evidence of Indebtedness. (a) Each Lender shall maintain in accordance with its usual practice appropriate
records evidencing the Indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable thereon and paid to such Lender from time to time under this
Agreement. The Administrative Agent shall maintain appropriate records in which shall be recorded (i) the Revolving Commitment of each Lender, (ii) the amount of each Loan made hereunder by each Lender, the Class and Type thereof and the
Interest Period applicable thereto, (iii) the date of each continuation thereof pursuant to Section 2.6, (iv) the date of each conversion of all or a portion thereof to another Type pursuant to Section 2.6,
(v) the date and amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder in respect of such Loans and (vi) both the date and amount of any sum received by the
Administrative Agent hereunder from the Borrower in respect of the Loans and each Lender’s Pro Rata Share thereof. The entries made in such records shall be prima facie evidence of the existence and amounts of the obligations of the
Borrower therein recorded; provided, that the failure or delay of any Lender or the Administrative Agent in maintaining or making entries into any such record or any error therein shall not in any manner affect the obligation of the Borrower
to repay the Loans (both principal and unpaid accrued interest) of such Lender in accordance with the terms of this Agreement. 
 (b) At the
request of any Lender (including the Swingline Lender) at any time, the Borrower agrees that it will execute and deliver to such Lender a Revolving Credit Note and, in the case of the Swingline Lender only, a Swingline Note, payable to the order of
such Lender. 
 Section 2.10. Prepayments. 
 (a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, without premium or penalty, by
giving irrevocable written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent no later than (i) in the case of prepayment of any Eurodollar Borrowing, 11:00 a.m. (New York time) not less than three
(3) Business Days prior to any such prepayment, (ii) in the case of any prepayment of any Base Rate Borrowing, not less than one Business Day prior to the date of such prepayment, and (iii) in the case of Swingline Borrowings, prior

any such notice, the Administrative Agent shall promptly notify each affected Lender of the contents thereof and of such Lender’s Pro Rata Share of any such 

  

 32 

 
prepayment. If such notice is given, the aggregate amount specified in such notice shall be due and payable on the date designated in such notice, together
with accrued interest to such date on the amount so prepaid in accordance with Section 2.11(d); provided, that if a Eurodollar Borrowing is prepaid on a date other than the last day of an Interest Period applicable thereto, the
Borrower shall also pay all amounts required pursuant to Section 2.17. Each partial prepayment of any Loan (other than a Swingline Loan) shall be in an amount that would be permitted in the case of an advance of a Revolving Borrowing of
the same Type pursuant to Section 2.2 or in the case of a Swingline Loan pursuant to Section 2.4. Each prepayment of a Borrowing shall be applied ratably to the Loans comprising such Borrowing. 
 (b) If at any time the Revolving Credit Exposure of all Lenders exceeds the Aggregate Revolving Commitment Amount, as reduced pursuant to
Section 2.7 or otherwise, the Borrower shall immediately repay Swingline Loans and Revolving Loans in an amount equal to such excess, together with all accrued and unpaid interest on such excess amount and any amounts due under
Section 2.17. Each prepayment shall be applied first to the Swingline Loans to the full extent thereof, second to the Base Rate Loans to the full extent thereof, and finally to Eurodollar Loans to the full extent thereof. If after giving
effect to prepayment of all Swingline Loans and Revolving Loans, the Revolving Credit Exposure of all Lenders exceeds the Aggregate Revolving Commitment Amount, the Borrower shall deposit in an account with the Administrative Agent, in the name of
the Administrative Agent and for the benefit of the Issuing Bank and the Lenders, an amount in cash equal to such excess plus any accrued and unpaid fees thereon to be held as collateral for the LC Exposure. Such account shall be administered
in accordance with Section 2.20(g) hereof. 
 Section 2.11. Interest on Loans. 
 (a) The Borrower shall pay interest on each Base Rate Loan at the Base Rate in effect from time to time and on each Eurodollar Loan at the Adjusted LIBO
Rate for the applicable Interest Period in effect for such Loan, plus, in each case, the Applicable Margin in effect from time to time. 
 (b) The Borrower shall pay interest on each Swingline Loan at the rate applicable to such Loan pursuant to Section 2.4(b). 
 (c) While an Event of Default exists or after acceleration, at the option of the Required Lenders, the Borrower shall pay interest (“Default Interest”) with respect to all Eurodollar Loans at the rate otherwise applicable
for the then-current Interest Period plus an additional 2% per annum until the last day of such Interest Period, and thereafter, and with respect to all Base Rate Loans (including all Swingline Loans) and all other Obligations hereunder
(other than Loans), at an all-in rate in effect for Base Rate Loans, plus an additional 2% per annum. 
 (d) Interest on the
principal amount of all Loans shall accrue from and including the date such Loans are made to but excluding the date of any repayment thereof. Interest on all outstanding Base Rate Loans shall be payable quarterly in arrears on the last day of each
March, June, September and December and on the Revolving Commitment Termination Date. Interest on all outstanding Eurodollar Loans shall be payable on the last day of each 

  

 33 

 
Interest Period applicable thereto, and, in the case of any Eurodollar Loans having an Interest Period in excess of three months or 90 days, respectively, on
each day which occurs every three months or 90 days, as the case may be, after the initial date of such Interest Period, and on the Revolving Commitment Termination Date. Interest on each Swingline Loan shall be payable on the maturity date of such
Loan, which shall be the last day of the Interest Period applicable thereto, and on the Revolving Commitment Termination Date. Interest on any Loan which is converted into a Loan of another Type or which is repaid or prepaid shall be payable on the
date of such conversion or on the date of any such repayment or prepayment (on the amount repaid or prepaid) thereof. All Default Interest shall be payable on demand. 
 (e) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder and shall promptly notify the Borrower and the Lenders of such rate in writing (or by telephone, promptly confirmed in
writing). Any such determination shall be conclusive and binding for all purposes, absent manifest error. 
 Section 2.12.
Fees. 
 (a) The Borrower shall pay to the Administrative Agent and the Syndication Agent for their own respective accounts fees in
the amounts and at the times previously agreed upon in writing by the Borrower and the Administrative Agent or the Syndication Agent, as applicable, including the amounts described in the Fee Letter. 
 (b) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a facility fee, which shall accrue at the Applicable Percentage
per annum (determined daily in accordance with Schedule I) on the daily amount of the Revolving Commitment (whether used or unused) of such Lender during the Availability Period; provided, that if such Lender continues to have any
Revolving Credit Exposure after the Revolving Commitment Termination Date, then the facility fee shall continue to accrue on the daily amount of such Revolving Credit Exposure from and after the Revolving Commitment Termination Date to the date that
all of such Lender’s Revolving Credit Exposure has been paid in full. 
 (c) The Borrower agrees to pay to the Administrative Agent for
the account of each Lender a utilization fee, which shall accrue at the Applicable Percentage per annum (determined daily in accordance with Schedule I) on the daily amount of the Revolving Credit Exposure for each day that the Revolving
Credit Exposure on such date equals or exceeds 50% of the Aggregate Revolving Commitment Amount on such date during the Availability Period; provided that if the Lenders continue to have Revolving Credit Exposure that equals or exceeds 50% of
the Aggregate Revolving Commitment Amount after the Revolving Commitment Termination Date, then the utilization fee shall continue to accrue on the daily amount of such Revolving Credit Exposure from and after the Revolving Commitment Termination
Date to the date that all of such Revolving Credit Exposure has been paid in full. 
 (d) The Borrower agrees to pay (i) to the
Administrative Agent, for the account of each Lender, a letter of credit fee with respect to its participation in each Letter of Credit, which shall accrue at a rate per annum equal to the Applicable Margin for Eurodollar Loans then in effect on the
average daily amount of such Lender’s LC Exposure attributable to such Letter of Credit during the period from and including the date of issuance of such Letter of 

  

 34 

 
Credit to but excluding the date on which such Letter of Credit expires or is drawn in full (including without limitation any LC Exposure that remains
outstanding after the Revolving Commitment Termination Date) and (ii) to the Issuing Bank for its own account a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any
portion thereof attributable to unreimbursed LC Disbursements) during the Availability Period (or until the date that such Letter of Credit is irrevocably cancelled, whichever is later), as well as the Issuing Bank’s standard fees with respect
to issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Notwithstanding the foregoing, if the Required Lenders elect to increase the interest rate on the Loans to the Default Interest pursuant to
Section 2.11(c), the rate per annum used to calculate the letter of credit fee pursuant to clause (i) above shall automatically be increased by an additional 2% per annum. 
 (e) The Borrower shall pay to the Administrative Agent all other fees previously agreed upon by the Borrower and the Administrative Agent in the Fee
Letter, which shall be due and payable on the Restatement Date. 
 (f) Accrued fees under paragraphs (b), (c) and (d) above shall
be payable quarterly in arrears on the last day of each March, June, September and December, and on the Revolving Commitment Termination Date (and if later, the date the Loans and LC Exposure shall be repaid in their entirety); provided
further, that any such fees accruing after the Revolving Commitment Termination Date shall be payable on demand. 
 Section 2.13.
Computation of Interest and Fees. Interest hereunder based on the Administrative Agent’s prime lending rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days
elapsed (including the first day but excluding the last day). All other interest and all fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day).
Each determination by the Administrative Agent of an interest amount or fee hereunder shall be made in good faith and, except for manifest error, shall be final, conclusive and binding for all purposes. 
 Section 2.14. Inability to Determine Interest Rates. If prior to the commencement of any Interest Period for any Eurodollar Borrowing,

 (i) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower)
that, by reason of circumstances affecting the relevant interbank market, adequate means do not exist for ascertaining LIBOR for such Interest Period, or 
 (ii) the Administrative Agent shall have received notice from the Required Lenders that the Adjusted LIBO Rate does not adequately and fairly reflect the cost to such Lenders (or Lender, as the case may be) of making,
funding or maintaining their (or its, as the case may be) Eurodollar Loans for such Interest Period, 
 the Administrative Agent shall give written notice
(or telephonic notice, promptly confirmed in writing) to the Borrower and to the Lenders as soon as practicable thereafter. In the case of 

  

 35 

 
Eurodollar Loans, until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist,
(i) the obligations of the Lenders to make Eurodollar Revolving Loans or to continue or convert outstanding Loans as or into Eurodollar Loans shall be suspended and (ii) all such affected Loans shall be converted into Base Rate Loans on
the last day of the then current Interest Period applicable thereto unless the Borrower prepays such Loans in accordance with this Agreement. Unless the Borrower notifies the Administrative Agent at least one Business Day before the date of any
Eurodollar Revolving Borrowing for which a Notice of Revolving Borrowing has previously been given that it elects not to borrow on such date, then such Revolving Borrowing shall be made as a Base Rate Borrowing. 
 Section 2.15. Illegality. If any Change in Law shall make it unlawful or impossible for any Lender to make, maintain or fund
any Eurodollar Loan and such Lender shall so notify the Administrative Agent, the Administrative Agent shall promptly give notice thereof to the Borrower and the other Lenders, whereupon until such Lender notifies the Administrative Agent and the
Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Eurodollar Revolving Loans, or to continue or convert outstanding Loans as or into Eurodollar Loans, shall be suspended. In the
case of the making of a Eurodollar Revolving Borrowing, such Lender’s Revolving Loan shall be made as a Base Rate Loan as part of the same Revolving Borrowing for the same Interest Period and if the affected Eurodollar Loan is then outstanding,
such Loan shall be converted to a Base Rate Loan either (i) on the last day of the then current Interest Period applicable to such Eurodollar Loan if such Lender may lawfully continue to maintain such Loan to such date or (ii) immediately
if such Lender shall determine that it may not lawfully continue to maintain such Eurodollar Loan to such date. Notwithstanding the foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different
Applicable Lending Office if such designation would avoid the need for giving such notice and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion. 
 Section 2.16. Increased Costs. 
 (a) If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special
deposit or similar requirement that is not otherwise included in the determination of the Adjusted LIBO Rate hereunder against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement
reflected in the Adjusted LIBO Rate) or the Issuing Bank; or 
 (ii) impose on any Lender or on the Issuing Bank or the
eurodollar interbank market any other condition affecting this Agreement or any Eurodollar Loans made by such Lender or any Letter of Credit or any participation therein; 
 and the result of either of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining a Eurodollar Loan or to increase the cost to such Lender or the Issuing Bank of
participating in or issuing any Letter of Credit or to reduce the amount received or receivable by such Lender or the Issuing Bank hereunder (whether of 

  

 36 

 
principal, interest or any other amount), then the Borrower shall promptly pay, upon written notice from and demand by such Lender on the Borrower (with a
copy of such notice and demand to the Administrative Agent), to the Administrative Agent for the account of such Lender, within five Business Days after the date of such notice and demand, additional amount or amounts sufficient to compensate such
Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered. 
 (b) If any Lender or the Issuing
Bank shall have determined that on or after the date of this Agreement any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital (or on the
capital of such Lender’s or the Issuing Bank’s parent corporation) 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 the Issuing Bank or such
Lender’s or the Issuing Bank’s parent corporation could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies or the policies of such Lender’s or the Issuing
Bank’s parent corporation with respect to capital adequacy) then, from time to time, within five (5) Business Days after receipt by the Borrower of written demand by such Lender (with a copy thereof to the Administrative Agent), the
Borrower shall pay to such Lender such additional amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s parent corporation for any such reduction suffered. 
 (c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or such
Lender’s or the Issuing Bank’s parent corporation, as the case may be, specified in paragraph (a) or (b) of this Section 2.16 shall be delivered to the Borrower (with a copy to the Administrative Agent) and shall be
conclusive, absent manifest error. The Borrower shall pay any such Lender or the Issuing Bank, as the case may be, such amount or amounts within 10 days after receipt thereof. 
 (d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 2.16 shall not constitute
a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided, that the Borrower shall not be required to compensate a Lender or the Issuing Bank under this Section 2.16 for any increased
costs or reductions incurred more than 90 days prior to the date that such Lender or the Issuing Bank notifies the Borrower of such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation
therefor; provided further, that if the Change in Law giving rise to such increased costs or reductions is retroactive, then such 90 day period shall be extended to include the period of such retroactive effect. 
 Section 2.17. Funding Indemnity. In the event of (a) the payment of any principal of a Eurodollar Loan other than on the
last day of the Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion or continuation of a Eurodollar Loan other than on the last day of the Interest Period applicable thereto or (c) the
failure by the Borrower to borrow, prepay, convert or continue any Eurodollar Loan on the date specified in any applicable notice (regardless of whether such notice is withdrawn or revoked). In the case of a Eurodollar Loan, such loss, cost or
expense shall be deemed to include an amount determined by such Lender to be the excess, if any, of (A) the amount of interest that would have accrued on the principal amount of such Eurodollar Loan if such event had not occurred at the
Adjusted 

  

 37 

 
LIBO Rate applicable to such Eurodollar Loan for the period from the date of such event to the last day of the then current Interest Period therefor (or in
the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Eurodollar Loan) over (B) the amount of interest that would accrue on the principal amount of such Eurodollar Loan for the
same period if the Adjusted LIBO Rate were set on the date such Eurodollar Loan was prepaid or converted or the date on which the Borrower failed to borrow, convert or continue such Eurodollar Loan. A certificate as to any additional amount payable
under this Section 2.17 submitted to the Borrower by any Lender (with a copy to the Administrative Agent) shall be conclusive, absent manifest error. 
 Section 2.18. Taxes. 
 (a) Any and all payments by or on account of any obligation of the
Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided, that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.18) the Administrative Agent, any Lender or the
Issuing Bank (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to
the relevant Governmental Authority in accordance with applicable law. 
 (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law. 
 (c) The Borrower shall indemnify the Administrative Agent, each Lender
and the Issuing Bank, within five (5) Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with
respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.18) and any penalties,
interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of
such payment or liability delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error. 
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver
to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the
Administrative Agent. 
 (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Code or any
treaty to which the United States is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly 

  

 38 

 
completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without
withholding or at a reduced rate. Without limiting the generality of the foregoing, each Foreign Lender agrees that it will deliver to the Administrative Agent and the Borrower (or in the case of a Participant, to the Lender from which the related
participation shall have been purchased), as appropriate, two (2) duly completed copies of (i) Internal Revenue Service Form W-8 ECI, or any successor form thereto, certifying that the payments received from the Borrower hereunder are
effectively connected with such Foreign Lender’s conduct of a trade or business in the United States; or (ii) Internal Revenue Service Form W-8 BEN, or any successor form thereto, certifying that such Foreign Lender is entitled to benefits
under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest; or (iii) Internal Revenue Service Form W-8 BEN, or any successor form prescribed by the Internal Revenue
Service, together with a certificate (A) establishing that the payment to the Foreign Lender qualifies as “portfolio interest” exempt from U.S. withholding tax under Code section 871(h) or 881(c), and (B) stating that
(1) the Foreign Lender is not a bank for purposes of Code section 881(c)(3)(A), or the obligation of the Borrower hereunder is not, with respect to such Foreign Lender, a loan agreement entered into in the ordinary course of its trade or
business, within the meaning of that section; (2) the Foreign Lender is not a 10% shareholder of the Borrower within the meaning of Code section 871(h)(3) or 881(c)(3)(B); and (3) the Foreign Lender is not a controlled foreign corporation
that is related to the Borrower within the meaning of Code section 881(c)(3)(C); or (iv) such other Internal Revenue Service forms as may be applicable to the Foreign Lender, including Forms W-8 IMY or W-8 EXP. Each such Foreign Lender shall
deliver to the Borrower and the Administrative Agent such forms on or before the date that it becomes a party to this Agreement (or in the case of a Participant, on or before the date such Participant purchases the related participation). In
addition, each such Foreign Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Foreign Lender. Each such Foreign Lender shall promptly notify the Borrower and the Administrative
Agent at any time that it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the Internal Revenue Service for such purpose). 
 Section 2.19. Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 
 (a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements,
or of amounts payable under Sections 2.16, 2.17 or 2.18, or otherwise) prior to 12:00 noon (New York time) on the date when due, in immediately available funds, free and clear of any defenses, rights of set-off, counterclaim, or
withholding or deduction of taxes. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon.
All such payments shall be made to the Administrative Agent at the Payment Office, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.16,
2.17 and 2.18 and 10.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly
following receipt thereof. If any payment hereunder shall be due on a day that is not a Business 

  

 39 

 
Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be
made payable for the period of such extension. All payments hereunder shall be made in Dollars. 
 (b) If at any time insufficient funds are
received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then
due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 
 (c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Revolving Loans or participations in LC Disbursements or Swingline Loans that
would result in such Lender receiving payment of a greater proportion of the aggregate amount of its Revolving Loans and participations in LC Disbursements and Swingline Loans and accrued interest thereon than the proportion received by any other
Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Revolving Loans and participations in LC Disbursements and Swingline Loans of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Revolving Loans and participations in LC Disbursements and Swingline Loans;
provided, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery,
without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as
consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements or Swingline Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to
which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may
exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation. 
 (d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative
Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance
upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount or amounts due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be,
severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the
date of payment 

  

 40 

 
to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation. 
 (e) If any Lender shall fail to make any payment required to be made by it pursuant to
Section 2.4(b), 2.5(b), 2.19(d), 2.20(d) or (e) or 10.3(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter
received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 
 Section 2.20. Letters of Credit. 
 (a) At any time before the fifth Business Day prior to expiration of the Availability Period, the Issuing Bank, in reliance upon the agreements of the other Lenders pursuant to Section 2.20(d), agrees to
issue, at the request of the Borrower, Letters of Credit for the account of the Borrower or any of its Subsidiaries on the terms and conditions hereinafter set forth; provided, that (i) each Letter of Credit shall expire on the earlier
of (A) the date one year after the date of issuance of such Letter of Credit (or in the case of any renewal or extension thereof, one year after such renewal or extension) and (B) the date that is five (5) Business Days prior to the
Revolving Commitment Termination Date; (ii) each Letter of Credit shall be in a stated amount of at least $100,000; and (iii) the Borrower may not request any Letter of Credit, if, after giving effect to such issuance (A) the
aggregate LC Exposure would exceed the LC Commitment or (B) the aggregate Revolving Credit Exposure of all Lenders would exceed the Aggregate Revolving Commitment Amount. Each Lender shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Issuing Bank without recourse a participation in each Letter of Credit equal to such Lender’s Pro Rata Share of the aggregate amount available to be drawn under such Letter of Credit on the date of
issuance with respect to all Letters of Credit. Each issuance of a Letter of Credit shall be deemed to utilize the Revolving Commitment of each Lender by an amount equal to the amount of such participation. 
 (b) To request the issuance of a Letter of Credit (or any amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall give
the Issuing Bank and the Administrative Agent irrevocable written notice at least three (3) Business Days prior to the requested date of such issuance specifying the date (which shall be a Business Day) such Letter of Credit is to be issued (or
amended, extended or renewed, as the case may be), the expiration date of such Letter of Credit, the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend,
renew or extend such Letter of Credit. In addition to the satisfaction of the conditions in Article III, the issuance of such Letter of Credit (or any amendment which increases the amount of such Letter of Credit) will be subject to the
further conditions that such Letter of Credit shall be in such form and contain such terms as the Issuing Bank shall approve and that the Borrower shall have executed and delivered any additional applications, agreements and instruments relating to
such Letter of Credit as the Issuing Bank shall reasonably require; provided, that in the event of any conflict between such applications, agreements or instruments and this Agreement, the terms of this Agreement shall control. 
  

 41 

 (c) At least two Business Days prior to the issuance of any Letter of Credit, the Issuing Bank will
confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has received such notice and if not, the Issuing Bank will provide the Administrative Agent with a copy thereof. Unless the Issuing Bank has received
notice from the Administrative Agent on or before the Business Day immediately preceding the date the Issuing Bank is to issue the requested Letter of Credit (1) directing the Issuing Bank not to issue the Letter of Credit because such issuance
is not then permitted hereunder because of the limitations set forth in Section 2.20(a) or that one or more conditions specified in Article III are not then satisfied, then, subject to the terms and conditions hereof, the Issuing
Bank shall, on the requested date, issue such Letter of Credit in accordance with the Issuing Bank’s usual and customary business practices. 
 (d) The Issuing Bank shall examine all documents purporting to represent a demand for payment under a Letter of Credit promptly following its receipt thereof. The Issuing Bank shall notify the Borrower and the Administrative Agent of such
demand for payment and whether the Issuing Bank has made or will make a LC Disbursement thereunder; provided, that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing
Bank and the Lenders with respect to such LC Disbursement. The Borrower shall be irrevocably and unconditionally obligated to reimburse the Issuing Bank for any LC Disbursements paid by the Issuing Bank in respect of such drawing, without
presentment, demand or other formalities of any kind. Unless the Borrower shall have notified the Issuing Bank and the Administrative Agent prior to 11:00 a.m. (New York time) on the Business Day immediately prior to the date on which such drawing
is honored that the Borrower intends to reimburse the Issuing Bank for the amount of such drawing in funds other than from the proceeds of Revolving Loans, the Borrower shall be deemed to have timely given a Notice of Revolving Borrowing to the
Administrative Agent requesting the Lenders to make a Base Rate Borrowing on the date on which such drawing is honored in an exact amount due to the Issuing Bank; provided, that for purposes solely of such Borrowing, the conditions precedents
set forth in Section 3.2 hereof shall not be applicable. The Administrative Agent shall notify the Lenders of such Borrowing in accordance with Section 2.3, and each Lender shall make the proceeds of its Base Rate Loan
included in such Borrowing available to the Administrative Agent for the account of the Issuing Bank in accordance with Section 2.5. The proceeds of such Borrowing shall be applied directly by the Administrative Agent to reimburse the
Issuing Bank for such LC Disbursement. 
 (e) If for any reason a Base Rate Borrowing may not be (as determined in the sole discretion of the
Administrative Agent), or is not, made in accordance with the foregoing provisions, then each Lender (other than the Issuing Bank) shall be obligated to fund the participation that such Lender purchased pursuant to subsection (a) in an amount
equal to its Pro Rata Share of such LC Disbursement on and as of the date which such Base Rate Borrowing should have occurred. Each Lender’s obligation to fund its participation shall be absolute and unconditional and shall not be affected by
any circumstance, including without limitation (i) any setoff, counterclaim, recoupment, defense or other right that such Lender or any other Person may have against the Issuing Bank or any other Person for any reason whatsoever, (ii) the
existence of a Default or an Event of Default or the termination of the Aggregate Revolving Commitments, (iii) any adverse change in the condition (financial or otherwise) of the Borrower or any of its Subsidiaries, (iv) any breach of this
Agreement by the Borrower or any other 

  

 42 

 
Lender, (v) any amendment, renewal or extension of any Letter of Credit or (vi) any other circumstance, happening or event whatsoever, whether or
not similar to any of the foregoing. On the date that such participation is required to be funded, each Lender shall promptly transfer, in immediately available funds, the amount of its participation to the Administrative Agent for the account of
the Issuing Bank. Whenever, at any time after the Issuing Bank has received from any such Lender the funds for its participation in a LC Disbursement, the Issuing Bank (or the Administrative Agent on its behalf) receives any payment on account
thereof, the Administrative Agent or the Issuing Bank, as the case may be, will distribute to such Lender its Pro Rata Share of such payment; provided, that if such payment is required to be returned for any reason to the Borrower or to a trustee,
receiver, liquidator, custodian or similar official in any bankruptcy proceeding, such Lender will return to the Administrative Agent or the Issuing Bank any portion thereof previously distributed by the Administrative Agent or the Issuing Bank to
it. 
 (f) To the extent that any Lender shall fail to pay any amount required to be paid pursuant to paragraph (d) above on the due
date therefor, such Lender shall pay interest to the Issuing Bank (through the Administrative Agent) on such amount from such due date to the date such payment is made at a rate per annum equal to the Federal Funds Rate; provided, that if
such Lender shall fail to make such payment to the Issuing Bank within three (3) Business Days of such due date, then, retroactively to the due date, such Lender shall be obligated to pay interest on such amount at the rate set forth in
Section 2.11(c). 
 (g) If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives
notice from the Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for
the benefit of the Issuing Bank and the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid fees thereon; provided, that the obligation to deposit such cash collateral shall become effective
immediately, and such deposit shall become immediately due and payable, without demand or notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (g) or (h) of
Section 8.1. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Administrative Agent shall have exclusive dominion and
control, including the exclusive right of withdrawal, over such account. Borrower agrees to execute any documents and/or certificates to effectuate the intent of this paragraph. Other than any interest earned on the investment of such deposits,
which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest and profits, if any, on such investments shall accumulate in
such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it had not been reimbursed and to the extent so applied, shall be held for the satisfaction of the
reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, with the consent of the Required Lenders, be applied to satisfy other obligations of the Borrower under this Agreement
and the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not so applied as aforesaid) shall be returned to the
Borrower within three Business Days after all Events of Default have been cured or waived. 
  

 43 

 (h) Promptly following the end of each calendar quarter, the Issuing Bank shall deliver (through the
Administrative Agent) to each Lender and the Borrower a report describing the aggregate Letters of Credit outstanding at the end of such Fiscal Quarter. Upon the request of any Lender from time to time, the Issuing Bank shall deliver to such Lender
any other information reasonably requested by such Lender with respect to each Letter of Credit then outstanding. 
 (i) The Borrower’s
obligation to reimburse LC Disbursements hereunder shall be absolute, unconditional and irrevocable and shall be performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever and irrespective of any of the
following circumstances: 
 (i) Any lack of validity or enforceability of any Letter of Credit or this Agreement, or whether
any Letter of Credit was issued for the account of any Subsidiary of Borrower; 
 (ii) The existence of any claim, set-off,
defense or other right which the Borrower or any Subsidiary or Affiliate of the Borrower may have at any time against a beneficiary or any transferee of any Letter of Credit (or any Persons or entities for whom any such beneficiary or transferee may
be acting), any Lender (including the Issuing Bank) or any other Person, whether in connection with this Agreement or the Letter of Credit or any document related hereto or thereto or any unrelated transaction; 
 (iii) Any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any
statement therein being untrue or inaccurate in any respect; 
 (iv) Payment by the Issuing Bank under a Letter of Credit
against presentation of a draft or other document to the Issuing Bank that does not comply with the terms of such Letter of Credit; 
 (v) Any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.20, constitute a legal or equitable discharge of, or provide a right of setoff
against, the Borrower’s obligations hereunder; or 
 (vi) The existence of a Default or an Event of Default. 

Neither the Administrative Agent, the Issuing Bank, the Lenders nor any Related Party of any of the foregoing shall have any liability or
responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to above), or any error, omission,
interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical
terms or any consequence arising from causes beyond the control of the Issuing Bank; provided, that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any actual direct damages (as
opposed to special, indirect (including claims for lost profits or other 

  

 44 

 
consequential damages), or punitive damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered
by the Borrower that are caused by the Issuing Bank’s failure to exercise due care when determining whether drafts or other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree, that in
the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised due care in each such determination. In
furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank
may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if
such documents are not in strict compliance with the terms of such Letter of Credit. 
 (j) Each Letter of Credit shall be subject to the
Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, or the International Standby Practices (1998 Revision), International Chamber of Commerce Publication No. 590, in
each case as the same may be amended from time to time, and, to the extent not inconsistent therewith, the governing law of this Agreement set forth in Section 10.5. 
 (k) For all purposes of this Agreement, the letter of credit issued by SunTrust Bank, in its capacity as Issuing Bank under the existing Credit
Agreement, on May 2, 2006, for the account of the Borrower (formerly Northern Border Partners, L.P.) in favor of Western Gas Resources in the sum of $10,000,000, shall constitute a Letter of Credit issued pursuant to this
Section 2.20 of this Agreement effective as of the Restatement Date. 
 Section 2.21. Increase of Commitments;
Additional Lenders. 
 (a) So long as no Event of Default has occurred and is continuing, from time to time after the Restatement
Date, the Borrower may, upon at least 30 days’ written notice to the Administrative Agent and each of the Lenders that the Borrower selects for participation, propose to increase the Aggregate Revolving Commitments to an amount not to exceed
$1,000,000,000 (the amount of any such increase, the “Additional Commitment Amount”). The Borrower may also invite one or more Eligible Assignees to become additional Lenders for all or any part of the Additional Commitment Amount
provided that any new bank or financial institution must be reasonably acceptable to the Administrative Agent and shall execute a joinder agreement in form and substance satisfactory to the Administrative Agent. Each selected Lender (and Eligible
Assignee, if applicable) shall have the right for a period of 15 days following receipt of such notice, to elect by written notice to the Borrower and the Administrative Agent to increase its Revolving Commitment by a principal amount of the
Additional Commitment Amount as indicated in such notice. No Lender (or any successor thereto) shall have any obligation to increase its Revolving Commitment or its other obligations under this Agreement and the other Loan Documents, and any
decision by a Lender to increase its Revolving Commitment shall be made in its sole discretion independently from any other Lender. 
  

 45 

 (b) If any Lender shall not elect to increase its Revolving Commitment pursuant to subsection (a) of
this Section 2.21, the Borrower may designate another bank or other financial institution (which may be, but need not be, one or more of the existing Lenders) which at the time agrees to, in the case of any such Person that is an
existing Lender, increase its Revolving Commitment and in the case of any other such Person (an “Additional Lender”), become a party to this Agreement; provided, however, that any new bank or financial institution must be
reasonably acceptable to the Administrative Agent. The sum of the increases in the Revolving Commitments of the existing Lenders pursuant to this subsection (b) plus the Revolving Commitments of the Additional Lenders shall not in the aggregate
exceed the unsubscribed amount of the Additional Commitment Amount. 
 (c) An increase in the Aggregate Revolving Commitments pursuant to
this Section 2.21 shall become effective upon the receipt by the Administrative Agent of an supplement or joinder in form and substance satisfactory to the Administrative Agent executed by the Borrower and by each Additional Lender and
by each other Lender whose Revolving Commitment is to be increased, setting forth the new Revolving Commitments of such Lenders and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the
terms and provisions hereof, together with Notes evidencing such increase in the Revolving Commitments, and such evidence of appropriate organizational authorization on the part of the Borrower with respect to the increase in the Revolving
Commitments and such opinions of counsel for the Borrower with respect to the increase in the Revolving Commitments as the Administrative Agent may reasonably request. 
 (d) Upon the acceptance of any such agreement by the Administrative Agent, the Aggregate Revolving Commitment Amount shall automatically be increased by the amount of the Revolving Commitments added through such
agreement and Schedule II shall automatically be deemed amended to reflect the Revolving Commitments of all Lenders after giving effect to the addition of such Revolving Commitments. 
 (e) Upon any increase in the Aggregate Revolving Commitments pursuant to this Section 2.21 that is not pro rata among all Lenders,
(x) within five Business Days, in the case of any Base Rate Loans then outstanding, and at the end of the then current Interest Period with respect thereto, in the case of any Eurodollar Loans then outstanding, the Borrower shall prepay such
Loans in their entirety and, to the extent the Borrower elects to do so and subject to the conditions specified in Article III, the Borrower shall reborrow Loans from the Lenders in proportion to their respective Revolving Commitments after
giving effect to such increase, until such time as all outstanding Loans are held by the Lenders in proportion to their respective Commitments after giving effect to such increase and (y) effective upon such increase, the amount of the
participations held by each Lender in each Letter of Credit then outstanding shall be adjusted automatically such that, after giving effect to such adjustments, the Lenders shall hold participations in each such Letter of Credit in proportion to
their respective Revolving Commitments. 
 Section 2.22. Mitigation of Obligations. If any Lender requests compensation
under Section 2.16, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18, then such Lender shall use reasonable efforts
to designate a different lending office for 

  

 46 

 
funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the sole
judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable under Section 2.16 or Section 2.18, as the case may be, in the future and (ii) would not subject such Lender to
any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all costs and expenses incurred by any Lender in connection with such designation or assignment. 
 Section 2.23. Extension of Maturity Date. 
 (a) Requests for Extension. After the first anniversary of the Restatement Date, the Borrower may, by written notice to the Administrative Agent (who shall promptly notify the Lenders), not later than 45 days
prior to the Maturity Date then in effect hereunder (the “Existing Maturity Date”), request the Lenders to extend such Existing Maturity Date for an additional year. The Borrower shall not make any such request more than once during
any twelve month period or more than twice during the term of this Agreement. The date any such written request is received by the Administrative Agent is the “Request Date”, and such request shall specify the date (the
“Extension Effective Date”) such extension would become effective; provided that such Extension Effective Date must be a Business Day and shall be at least 45 days, and not more than 60 days, after the Request Date.

 (b) Lender Elections to Extend. Each Lender, acting in its sole and individual discretion, shall, by notice to the Administrative
Agent given not later than 15 days after the Request Date (or such later date as the Borrower and Administrative Agent may agree), advise the Administrative Agent whether or not such Lender agrees to such extension. Each Lender that determines not
to so extend its Maturity Date, or that fails to advise the Administrative Agent as to its election under this Section 2.23(b), shall be a “Non-Extending Lender” for purposes of this Section. The Revolving Commitment of
each Non-Extending Lender shall be terminated on the Existing Maturity Date for such Lender (without regard to extensions by any other Lenders) and on such Existing Maturity Date the Borrower shall pay in full the unpaid principal amount of all
Loans owing to such Non-Extending Lender, together with all accrued and unpaid interest thereon and all fees accrued under this Agreement and unpaid to such date, and all other amounts then due to such Non-Extending Lender under this Agreement. The
election of any Lender to agree to such extension (each such Lender is herein called an “Extending Lender”) shall not obligate any other Lender to so agree. 
 (c) Notification by Administrative Agent. The Administrative Agent shall promptly notify the Borrower of each Lender’s determination under
this Section and shall promptly notify the Extending Lenders of the aggregate Revolving Commitments of the Non-Extending Lenders. 
 (d)
Increased and Additional Commitments. Each Extending Lender may offer to increase its respective Revolving Commitment by an amount not to exceed the aggregate amount of the Non-Extending Lenders’ Revolving Commitments, and such Extending
Lender shall deliver to the Administrative Agent a notice of its offer to so increase its Revolving Commitment no later than 20 days after the Request Date (or such later date to which the Borrower and the Administrative Agent shall agree), and such
offer shall be irrevocable until the 

  

 47 

 
Extension Effective Date. To the extent the aggregate amount of additional Revolving Commitments that the Extending Lenders offer pursuant to the preceding
sentence exceeds the aggregate amount of the Non-Extending Lenders’ Revolving Commitments, such additional Revolving Commitments shall be reduced on a pro rata basis. To the extent the aggregate amount of Revolving Commitments
that the Extending Lenders have so offered to extend is less than the aggregate amount of the Revolving Commitments that the Borrower has so requested to be extended, the Borrower shall have the right but not the obligation to require any
Non-Extending Lender to (and any such Non-Extending Lender shall) assign in full its rights and obligations under this Agreement to one or more Extending Lenders or other banks or financial institutions qualifying as Eligible Assignees and otherwise
reasonably acceptable to the Administrative Agent, which at the time agree to, in the case of any Extending Lender, increase its Revolving Commitment, and in the case of any new Lender (each, an “Additional Commitment Lender”)
become a party to this Agreement; provided that (i) such assignment is otherwise in compliance with all requirements and provisions of Section 10.4(b), (ii) such Non-Extending Lender receives payment in full of the
unpaid principal amount of all Loans owing to such Non-Extending Lender, together with all accrued and unpaid interest thereon and all fees accrued under this Agreement and unpaid to such date, and all other amounts then due to such Non-Extending
Lender under this Agreement, and (iii) any such assignment shall be effective on the date on or before such Extension Effective Date as may be specified by the Borrower and agreed to by the respective Extending Lenders and Additional Commitment
Lenders, as the case may be, and the Administrative Agent. 
 (e) Minimum Extension Requirement. If (and only if) the total of the
Revolving Commitments of the Lenders that have agreed so to extend the then Existing Maturity Date and the additional Revolving Commitments of the Additional Commitment Lenders shall be more than 50% of the aggregate amount of the Revolving
Commitments in effect on the Request Date, then, effective as of the Extension Effective Date, the Maturity Date of each Extending Lender and of each such Additional Commitment Lender shall be extended to the date falling one year after the Existing
Maturity Date of each such Extending Lender (except that, if such date is not a Business Day, such Maturity Date as so extended shall be the next preceding Business Day) and each Additional Commitment Lender shall thereupon become a
“Lender” for all purposes of this Agreement. 
 (f) Conditions to Effectiveness of Extensions. Notwithstanding the
foregoing, the extension of the Maturity Date pursuant to this Section shall not be effective with respect to any Lender unless: 
 (i) no Default shall have occurred and be continuing on the date of such extension and after giving effect thereto; 
 (ii) the representations and warranties contained in this Agreement are true and correct on and as of the date of such extension and after giving effect thereto, as though made on and as of such date (or, if any such representation or
warranty is expressly stated to have been made as of a specific date, as of such specific date); 
 (iii) on the Maturity Date
applicable to each Non-Extending Lender, the Borrower shall prepay any Revolving Loans and Swingline Borrowings outstanding 

  

 48 

 
on such date, accrued interest thereon, accrued fees payable hereunder, and any additional amounts required pursuant to Section 2.17, to the
extent necessary to satisfy in full Obligations due to such Non-Extending Lender as of such date; and 
 (iv) on the Maturity
Date applicable to each Non-Extending Lender, the Borrower shall cash collateralize any existing Letters of Credit or make other credit accommodations satisfactory to the Issuing Bank with respect to such Letters of Credit to the extent that, after
giving effect to the prepayment required by the preceding clause (iii), the Revolving Credit Exposure exceeds the Revolving Commitments of the remaining Lenders. 
 ARTICLE III 
 CONDITIONS PRECEDENT TO LOANS AND LETTERS OF CREDIT

 50

occasion of any Borrowing and of the Issuing Bank to issue, amend, renew or extend any Letter of Credit is subject to the satisfaction of the following conditions: 
 (a) at the time of and immediately after giving effect to such Borrowing or the issuance, amendment, renewal or extension of such Letter of Credit, as applicable, no Default or Event of Default shall exist;

 (b) at the time of and immediately after giving effect to such Borrowing or the issuance, amendment, renewal or extension of such Letter

 Section 3.3. Delivery of Documents. All of the Loan Documents, certificates, legal opinions and other documents and papers referred to in this Article III, unless otherwise specified, shall be delivered to the

 ARTICLE IV 
 REPRESENTATIONS AND WARRANTIES 
 The Borrower represents and warrants to the Administrative Agent and each Lender as
follows: 
 Section 4.1. Existence; Power. The Borrower and each of its Subsidiaries (i) is duly organized, validly
existing and in good standing as a corporation, partnership or limited liability company under the laws of the jurisdiction of its organization, (ii) has all requisite power and authority to carry on its business as now conducted, and
(iii) is duly qualified to do business, and is in good standing, in each jurisdiction where such qualification is required, except where a failure to be so qualified could not reasonably be expected to result in a Material Adverse Effect.

  

 51 

 Section 4.2. Organizational Power; Authorization. The execution, delivery and
performance by each Loan Party of the Loan Documents to which it is a party are within such Loan Party’s organizational powers and have been duly authorized by all necessary organizational, and if required, shareholder, partner or member,
action. This Agreement has been duly executed and delivered by the Borrower, and constitutes, and each other Loan Document to which any Loan Party is a party, when executed and delivered by such Loan Party, will constitute, valid and binding
obligations of the Borrower or such Loan Party (as the case may be), enforceable against it in accordance with their respective terms, except as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws
affecting the enforcement of creditors’ rights generally and by general principles of equity. 
 Section 4.3.
Governmental Approvals; No Conflicts. The execution, delivery and performance by the Borrower of this Agreement, and by each Loan Party of the other Loan Documents to which it is a party (a) do not require any consent or
approval of, registration or filing with, or any action by, any Governmental Authority, except those as have been obtained or made and are in full force and effect, (b) will not violate any Requirements of Law applicable to the Borrower or any
of its Subsidiaries or any judgment, order or ruling of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument binding on the Borrower or any of its Subsidiaries or any of its
assets or give rise to a right thereunder to require any payment to be made by the Borrower or any of its Subsidiaries, in each case other than violations, defaults or rights which could not reasonably expected to result in a Material Adverse
Effect, and (d) will not result in the creation or imposition of any Lien on any asset of the Borrower or any of its Subsidiaries, except Liens (if any) created under the Loan Documents. 
 Section 4.4. Financial Statements. The Borrower has furnished to each Lender the audited consolidated balance sheet of the
Borrower and its Subsidiaries as of December 31, 2006 and the related consolidated statements of income, owners’ equity and cash flows for the Fiscal Year then ended, together with the audit report of KPMG LLP or other independent public
accountants of nationally recognized standing. Such financial statements fairly present the consolidated financial condition of the Borrower and its Subsidiaries as of such dates and the consolidated results of operations for such periods in
conformity with GAAP consistently applied. 
 Section 4.5. Litigation and Environmental Matters. 
 (a) No litigation, investigation or proceeding of or before any arbitrators or Governmental Authorities is pending against or, to the knowledge of the
Borrower, threatened against or affecting the Borrower or any of its Subsidiaries (i) as to which there is a reasonable possibility of an adverse determination that could reasonably be expected to have, either individually or in the aggregate,
a Material Adverse Effect or (ii) which in any manner draws into question the validity or enforceability of this Agreement or any other Loan Document. 
 (b) Except for the matters set forth on Schedule 4.5(b), neither the Borrower nor any of its Subsidiaries (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any
permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any 

  

 52 

 
claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability, that, in each case, could reasonably be
expected to have, either individually or in the aggregate, a Material Adverse Effect. 
 Section 4.6. Compliance with Laws
and Agreements. The Borrower and each Subsidiary is in compliance with (a) all Requirements of Law and all judgments, decrees and orders of any Governmental Authority and (b) all indentures, agreements or other instruments binding
upon it or its properties, except where non-compliance, either singly or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 
 Section 4.7. Investment Company Act, Etc. Neither the Borrower nor any of its Subsidiaries is (a) an “investment company” or is “controlled” by an “investment
company”, as such terms are defined in, or subject to regulation under, the Investment Company Act of 1940, as amended, or (b) otherwise subject to any other regulatory scheme limiting its ability to incur debt or requiring any approval or
consent from or registration or filing with, any Governmental Authority in connection therewith. 
 Section 4.8.
Taxes. The Borrower and its Subsidiaries and each other Person for whose taxes the Borrower or any Subsidiary could become liable have timely filed or caused to be filed, or received extensions of time for the filing of, all
Federal income tax returns and all other material tax returns that are required to be filed by them, and have paid all taxes shown to be due and payable on such returns or on any assessments made against it or its property and all other taxes, fees
or other charges imposed on it or any of its property by any Governmental Authority, except where the same are currently being contested in good faith by appropriate proceedings and for which the Borrower or such Subsidiary, as the case may be, has
set aside on its books adequate reserves in accordance with GAAP. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of such taxes are adequate, and no tax liabilities that could be materially in excess
of the amount so provided are anticipated. 
 Section 4.9. Margin Regulations. None of the proceeds of any of the
Loans or Letters of Credit will be used, directly or indirectly, for “purchasing” or “carrying” any “margin stock” with the respective meanings of each of such terms under Regulation U of the Board of Governors of the
Federal Reserve System as now and from time to time hereafter in effect or for any purpose that violates the provisions of the Regulation U. Neither the Borrower nor its Subsidiaries is engaged principally, or as one of its important activities, in
the business of extending credit for the purpose of purchasing or carrying “margin stock.” 
 Section 4.10.
ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a
Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Standards No. 87) did not, as of the date of the most recent financial
statements reflecting such amounts, exceed the fair market value of the assets of such Plan, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial
Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed the fair market value of the assets of all such underfunded Plans. 
  

 53 

 Section 4.11. Ownership of Property. 
 (a) Each of the Borrower and its Subsidiaries has good title to, or valid leasehold or easement interests in, or the right to use, all of its real and

Rating Decline Offer (as such term is defined in the Senior Note Indentures), or the event causing such offer, under the Senior Notes or the election by one or more holders of Senior Note(s) to exercise its or their rights to have all or any portion
of their Senior Notes repurchased by the Borrower; or 
 (g) the Borrower or any Subsidiary shall (i) commence a voluntary case or other

 ARTICLE IX 
 THE ADMINISTRATIVE AGENT 
 Section 9.1. Appointment of Administrative Agent. 
 (a) Each Lender irrevocably appoints SunTrust Bank as the
Administrative Agent and authorizes it to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent under this Agreement and the other Loan Documents, together with all such actions and powers that are
reasonably incidental thereto. The Administrative Agent may perform any of its duties hereunder or under the other Loan Documents by or through any one or more sub-agents or attorneys-in-fact appointed by the Administrative Agent. The Administrative
Agent and any such sub-agent or attorney-in-fact may perform any and all of its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions set forth in this Article shall apply to any such
sub-agent or attorney-in-fact and the Related Parties of the Administrative Agent, any such sub-agent and any such attorney-in-fact and shall apply to their respective activities in connection with the syndication of the credit facilities provided
for herein as well as activities as Administrative Agent. 
 (b) The Issuing Bank shall act on behalf of the Lenders with respect to any
Letters of Credit issued by it and the documents associated therewith until such time and except for so long as the Administrative Agent may agree at the request of the Required Lenders to act for the Issuing Bank with respect thereto; provided,
that the Issuing Bank shall have all the benefits and immunities (i) provided to the Administrative Agent in this Article with respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it
or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article included the Issuing Bank with respect to
such acts or omissions and (ii) as additionally provided in this Agreement with respect to the Issuing Bank. 
 Section 9.2.
Nature of Duties of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in this Agreement 

  

 68 

 
and the other Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or
other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except
those discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 10.2), and (c) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose,
any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not
taken by it, its sub-agents or attorneys-in-fact with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 10.2) or
in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent
shall not be deemed to have knowledge of any Default or Event of Default unless and until written notice thereof (which notice shall include an express reference to such event being a “Default” or “Event of Default” hereunder) is
given to the Administrative Agent by the Borrower or any Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with
any Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements, or other
terms and conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in
Article III or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. The Administrative Agent may consult with legal counsel (including counsel for the Borrower)
concerning all matters pertaining to such duties. 
 Section 9.3. Lack of Reliance on the Administrative Agent. Each of
the Lenders, the Swingline Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each of the Lenders, the Swingline Lender and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and
based on such documents and information as it has deemed appropriate, continue to make its own decisions in taking or not taking of any action under or based on this Agreement, any related agreement or any document furnished hereunder or thereunder.

 Section 9.4. Certain Rights of the Administrative Agent. If the Administrative Agent shall request instructions from
the Required Lenders with respect to any action or actions (including the failure to act) in connection with this Agreement, the Administrative Agent shall be entitled to refrain from such act or taking such act, unless and until it shall have
received instructions from such Lenders; and the Administrative Agent shall 

  

 69 

 
not incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the
Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders where required by the terms of this Agreement. 
 Section 9.5. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any
liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed, sent or made by the proper Person. The Administrative Agent may also rely
upon any statement made to it orally or by telephone and believed by it to be made by the proper Person and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (including counsel for the
Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or not taken by it in accordance with the advice of such counsel, accountants or experts. 
 Section 9.6. The Administrative Agent in its Individual Capacity. The bank serving as the Administrative Agent shall have the
same rights and powers under this Agreement and any other Loan Document in its capacity as a Lender as any other Lender and may exercise or refrain from exercising the same as though it were not the Administrative Agent; and the terms
“Lenders”, “Required Lenders”, “holders of Notes”, or any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity. The bank acting as the
Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not the Administrative Agent hereunder.

 Section 9.7. Successor Administrative Agent. 
 (a) The Administrative Agent may resign at any time by giving 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, subject to the approval by the Borrower provided that no Default or Event of Default shall exist at such time. If no successor Administrative Agent shall have been so
appointed, and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor
Administrative Agent, which shall be a commercial bank organized under the laws of the United States of America or any state thereof or a bank which maintains an office in the United States, having a combined capital and surplus of at least
$500,000,000. 
 (b) Upon the acceptance of its appointment as the Administrative Agent hereunder by a successor, such successor
Administrative Agent shall thereupon 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. If within 45 days after written notice is given of the retiring Administrative Agent’s resignation under this Section 9.7 no successor Administrative Agent shall have been appointed
and shall have accepted such appointment, then on such 45th day (i) the retiring Administrative Agent’s resignation shall become effective, (ii) the retiring Administrative Agent shall thereupon be discharged from its duties and
obligations 

  

 70 

 
under the Loan Documents and (iii) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Loan
Documents until such time as the Required Lenders appoint a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation hereunder, the provisions of this Article shall continue in effect for the
benefit of such retiring Administrative Agent and its representatives and agents in respect of any actions taken or not taken by any of them while it was serving as the Administrative Agent. 
 Section 9.8. Authorization to Execute other Loan Documents. Each Lender hereby authorizes the Administrative Agent to execute on
behalf of all Lenders all Loan Documents other than this Agreement. 
 Section 9.9. Syndication Agent and Co-Documentation
Agents. Each Lender hereby designates Wachovia Bank, National Association as Syndication Agent and agrees that the Syndication Agent shall have no duties or obligations under any Loan Documents to any Lender or any Loan Party. Each Lender
hereby designates BMO Capital Markets, Barclays Bank plc, and Citibank, N.A., as Co-Documentation Agents, and agrees that the Co-Documentation Agents shall have no duties or obligations under any Loan Documents to any Lender or any Loan Party.

hereunder by notice to the other parties hereto. All such notices and other communications shall, when transmitted by overnight delivery, or faxed, be effective when delivered for overnight (next-day) delivery, or transmitted in legible form by
facsimile machine, respectively, or if mailed, upon the third Business Day after the date deposited into the mail or if delivered, upon delivery; provided, that notices delivered to the Administrative Agent, the Issuing Bank or the Swingline Bank
shall not be effective until actually received by such Person at its address specified in this Section 10.1. 
 (b) Any agreement
of the Administrative Agent and the Lenders herein to receive certain notices by telephone or facsimile is solely for the convenience and at the request of the Borrower. The Administrative Agent and the Lenders shall be entitled to rely on the
authority of any Person purporting to be a Person authorized by the Borrower to give such notice and the Administrative Agent and Lenders shall not have any liability to the Borrower or other Person on account of any action taken or not taken by the
Administrative Agent or the Lenders in reliance upon such telephonic or facsimile notice. The obligation of the Borrower to repay the Loans and all other Obligations hereunder shall not be affected in any way or to any extent by any failure of the
Administrative Agent and the Lenders to receive written confirmation of any telephonic or facsimile notice or the receipt by the Administrative Agent and the Lenders of a confirmation which is at variance with the terms understood by the
Administrative Agent and the Lenders to be contained in any such telephonic or facsimile notice. 
 Section 10.2. Waiver;
Amendments. 
 (a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power
hereunder or any other Loan Document, and no course of dealing between the Borrower and the Administrative Agent or any Lender, shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power or any abandonment
or discontinuance of steps to enforce such right or power, preclude any other or further exercise thereof or the exercise of any other right or power hereunder or thereunder. The rights and remedies of the Administrative Agent, the Issuing Bank and
the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies provided by law. No waiver of any provision of this Agreement or any other Loan 

  

 73 

 
Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of
this Section 10.2, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or the issuance of a Letter
of Credit shall not be construed as a waiver of any Default or Event of Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default or Event of Default at the time.

 (b) No amendment or waiver of any provision of this Agreement or the other Loan Documents, nor consent to any departure by the Borrower
therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrower and the Required Lenders or the Borrower and the Administrative Agent with the consent of the Required Lenders and then such waiver or consent
shall be effective only in the specific instance and for the specific purpose for which given; provided, that no amendment or waiver shall: (i) increase the Commitment of any Lender without the written consent of such Lender,
(ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for
any payment of any principal of, or interest on, any Loan or LC Disbursement or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any
Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.19(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of
each Lender or waive or amend any condition set forth in Section 3.1, (v) change any of the provisions of this Section 10.2 or the definition of “Required Lenders” or any other provision hereof specifying the
number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; (vi) release any guarantor or limit the liability of
any such guarantor under any guaranty agreement, without the written consent of each Lender; (vii) release all or substantially all collateral (if any) securing any of the Obligations, without the written consent of each Lender; provided
further, that no such agreement shall amend, modify or otherwise affect the rights, duties or obligations of the Administrative Agent, the Swingline Bank or the Issuing Bank without the prior written consent of such Person. Notwithstanding
anything contained herein to the contrary, this Agreement may be amended and restated without the consent of any Lender (but with the consent of the Borrower and the Administrative Agent) if, upon giving effect to such amendment and restatement,
such Lender shall no longer be a party to this Agreement (as so amended and restated), the Commitments of such Lender shall have terminated (but such Lender shall continue to be entitled to the benefits of Sections 2.16, 2.17,
2.18 and 10.3), such Lender shall have no other commitment or other obligation hereunder and shall have been paid in full all principal, interest and other amounts owing to it or accrued for its account under this Agreement.

 Section 10.3. Expenses; Indemnification. 
 (a) The Borrower shall pay (i) all reasonable, out-of-pocket costs and expenses of the Administrative Agent, the Syndication Agent and their
Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, the Syndication Agent and their Affiliates, in connection with the syndication of the credit facilities 

  

 74 

 
provided for herein, the preparation of the Loan Documents and any amendments, modifications or waivers thereof (whether or not the transactions contemplated
in this Agreement or any other Loan Document shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand
for payment thereunder and (iii) all out-of-pocket costs and expenses (including, without limitation, the reasonable fees, charges and disbursements of outside counsel) incurred by the Administrative Agent, the Syndication Agent, the Issuing
Bank or any Lender in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section 10.3, or in connection with the Loans made or any Letters of Credit issued
hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit. 
 (b) The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), each Lender and the Issuing Bank, and each Related Party of any of the foregoing Persons (each such Person being called an
“Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall
indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower or
any other Loan Party arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties
hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use or proposed use of the proceeds therefrom (including any refusal
by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or
Release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective
claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower or any other Loan Party, and regardless of whether any
Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee, (y) result from a claim brought by the Borrower or any other Loan Party against an Indemnitee for breach in
bad faith of such Indemnitee’s obligations hereunder or under any other Loan Document, if the Borrower or such Loan Party has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent
jurisdiction or (z) result from a claim brought by one Indemnitee against another Indemnitee (other than the Administrative Agent, the Syndication Agent, the Swingline Lender or the Issuing Bank, in their capacities as such). 
 (c) The Borrower shall pay, and hold the Administrative Agent and each of the Lenders harmless from and against, any and all present and future stamp,
documentary, and other similar taxes with respect to this Agreement and any other Loan Documents, any collateral 

  

 75 

 
described therein, or any payments due thereunder, and save the Administrative Agent and each Lender harmless from and against any and all liabilities with
respect to or resulting from any delay or omission to pay such taxes. 
 (d) To the extent that the Borrower fails to pay any amount required
to be paid to the Administrative Agent, the Issuing Bank or the Swingline Lender under clauses (a), (b) or (c) hereof, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case
may be, such Lender’s Pro Rata Share (determined as of the time that the unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, that the unreimbursed expense or indemnified payment, claim, damage, liability
or related expense, as the case may be, was incurred by or asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such. 
 (e) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages
(as opposed to actual or direct damages) arising out of, in connection with or as a result of, this Agreement or any agreement or instrument contemplated hereby, the transactions contemplated therein, any Loan or any Letter of Credit or the use of
proceeds thereof. 
 (f) All amounts due under this Section 10.3 shall be payable promptly after written demand therefor.

 Section 10.4. Successors and Assigns. 
 (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer
any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this
Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in
this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section
and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
 (b) Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions: 
  

 76 

 (i) Minimum Amounts. 
 (A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing
to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and 
 (B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Revolving Credit Exposure outstanding thereunder) or, if the applicable
Commitment is not then in effect, the principal outstanding balance of the Revolving Credit Exposure of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is
delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Acceptance, as of the Trade Date) shall not be less than $1,000,000, unless each of the Administrative Agent and, so long as no Event of Default
has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed). 
 (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Revolving Credit Exposure
or the Commitment assigned. 
 (iii) Required Consents. No consent shall be required for any assignment except to the
extent required by paragraph (b)(i)(B) of this Section and, in addition: 
 (A) the consent of the Borrower (such consent not
to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

 (B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for
assignments to a Person that is not a Lender with a Commitment; and 
 (C) the consent of the Issuing Bank (such consent not
to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding), and the consent of the
Swingline Lender (such consent not to be unreasonably withheld or delayed) shall be required for any assignment in respect of the Revolving Credit Commitments. 
 (iv) Assignment and Acceptance. The parties to each assignment shall deliver to the Administrative Agent (A) a duly executed
Assignment and Acceptance, (B) a processing and recordation fee of $3,000, (C) an Administrative Questionnaire unless 

  

 77 

 the assignee is already a Lender and (D) the documents required under Section 2.18 if such assignee is a
Foreign Lender. 
 (v) No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the
Borrower’s Affiliates or Subsidiaries. 
 (vi) No Assignment to Natural Persons. No such assignment shall be made
to a natural person. 
 Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this
Section 10.4, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance, have
the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case
of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.19,
2.20, 2.21 and 10.3 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with
this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section 10.4. 
 (c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Atlanta, Georgia a copy
of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Revolving Credit Exposure owing to, each Lender pursuant to the terms
hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the
terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon
reasonable prior notice. 
 (d) Any Lender may at any time, without the consent of, or notice to, the Borrower, the Administrative Agent, the
Swingline Bank or the Issuing Bank sell participations to any Person (other than a natural person, the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such
Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Lenders, Issuing Bank and Swingline Lender shall continue to deal
solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. 
  

 78 

 (e) Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that
such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, modification or waiver with respect to the following to the extent affecting such Participant: (i) increase the Commitment of any Lender without the written consent of such Lender,
(ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for
any payment of any principal of, or interest on, any Loan or LC Disbursement or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any
Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.19(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of
each Lender, (v) change any of the provisions of this Section 10.4 or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or
modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; (vi) release any guarantor or limit the liability of any such guarantor under any guaranty agreement without the written
consent of each Lender except to the extent such release is expressly provided under the terms of the Guaranty Agreement; or (vii) release all or substantially all collateral (if any) securing any of the Obligations. Subject to paragraph
(e) of this Section 10.4, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.16, 2.17, and 2.18 to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to paragraph (b) of this Section 10.4. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.7 as though it were a Lender, provided such Participant
agrees to be subject to Section 2.19 as though it were a Lender. 
 (f) A Participant shall not be entitled to receive any
greater payment under Section 2.16 and Section 2.18 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such
Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.18 unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.18(e) as though it were a Lender. 
 (g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of
such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such
pledgee or assignee for such Lender as a party hereto. 
 Section 10.5. Governing Law; Jurisdiction; Consent to Service of
Process. 
 (a) This Agreement and the other Loan Documents shall be construed in accordance with and be governed by the law (without
giving effect to the conflict of law principles thereof) of the State of New York. 
  

 79 

 (b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the
non-exclusive jurisdiction of the United States District Court of the Southern District of New York, and of any state court of the State of Supreme Court of the State of New York sitting in New York county and any appellate court from any thereof,
in any action or proceeding arising out of or relating to this Agreement or any other Loan Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby
irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto
agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Loan Document shall
affect any right that the Administrative Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or its properties in the courts of any
jurisdiction. 
 (c) The Borrower irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of
venue of any such suit, action or proceeding described in paragraph (b) of this Section 10.5 and brought in any court referred to in paragraph (b) of this Section 10.5. Each of the parties hereto irrevocably waives, to
the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 (d) Each party to this Agreement irrevocably consents to the service of process in the manner provided for notices in Section 10.1. Nothing in this Agreement or in any other Loan Document will affect the
right of any party hereto to serve process in any other manner permitted by law. 
 Section 10.6. WAIVER OF JURY
TRIAL. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER
THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
 Section 10.7. Right of Setoff. In addition to any
rights now or hereafter granted under applicable law and not by way of limitation of any such rights, each Lender and the Issuing Bank shall have the right, at any time or from time to time upon the occurrence and during the continuance of an Event
of Default, without prior notice to the Borrower, any such 

  

 80 

 
notice being expressly waived by the Borrower to the extent permitted by applicable law, to set off and apply against all deposits (general or special, time
or demand, provisional or final) of the Borrower at any time held or other obligations at any time owing by such Lender and the Issuing Bank to or for the credit or the account of the Borrower against any and all Obligations held by such Lender or
the Issuing Bank, as the case may be, irrespective of whether such Lender or the Issuing Bank shall have made demand hereunder and although such Obligations may be unmatured. Each Lender and the Issuing Bank agree promptly to notify the
Administrative Agent and the Borrower after any such set-off and any application made by such Lender and the Issuing Bank, as the case may be; provided, that the failure to give such notice shall not affect the validity of such set-off and
application. 
 Section 10.8. Counterparts; Integration. This Agreement may be executed by one or more of the parties to
this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, the Fee Letter, the other Loan Documents, and any
separate letter agreement(s) relating to any fees payable to the Administrative Agent and the Co-Arrangers constitute the entire agreement among the parties hereto and thereto regarding the subject matters hereof and thereof and supersede all prior
agreements and understandings, oral or written, regarding such subject matters. 
 Section 10.9. Survival. All covenants,
agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto
and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the
Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the
principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The
provisions of Sections 2.16, 2.17, 2.18, and 10.3 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans,
the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof as the case may be. All representations and warranties made herein, in the certificates, reports, notices, and
other documents delivered pursuant to this Agreement shall survive the execution and delivery of this Agreement and the other Loan Documents, and the making of the Loans and the issuance of the Letters of Credit. 
 Section 10.10. Severability. Any provision of this Agreement or any other Loan Document held to be illegal, invalid or unenforceable
in any jurisdiction, shall, as to such jurisdiction, be ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or enforceability of the remaining provisions hereof or thereof; and the
illegality, invalidity or unenforceability of a particular provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
  

 81 

 Section 10.11. Confidentiality. Each of the Administrative Agent, the Issuing
Bank and each Lender agrees to take normal and reasonable precautions to maintain the confidentiality of any information designated in writing as confidential and provided to it by the Borrower or any Subsidiary, except that such information may be
disclosed (i) to any Related Party of the Administrative Agent, the Issuing Bank or any such Lender, including without limitation accountants, legal counsel and other advisors, (ii) to the extent required by applicable laws or regulations
or by any subpoena or similar legal process, (iii) to the extent requested by any regulatory agency or authority, (iv) to the extent that such information becomes publicly available other than as a result of a breach of this
Section 10.11, or which becomes available to the Administrative Agent, the Issuing Bank, any Lender or any Related Party of any of the foregoing on a nonconfidential basis from a source other than the Borrower, (v) in connection
with the exercise of any remedy hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, and (ix) subject to provisions substantially similar to this Section 10.11, to any actual
or prospective assignee or Participant, or (vi) with the consent of the Borrower. Any Person required to maintain the confidentiality of any information as provided for in this Section 10.11 shall be considered to have complied with
its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such Person would accord its own confidential information. 
 Section 10.12. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate
applicable to any Loan, together with all fees, charges and other amounts which may be treated as interest on such Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate of interest (the
“Maximum Rate”) which may be contracted for, charged, taken, received or reserved by a Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all
Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this
Section 10.12 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest
thereon at the Federal Funds Rate to the date of repayment, shall have been received by such Lender. 
 Section 10.13.
Waiver of Effect of Seal. The Borrower represents and warrants that neither it nor any other Loan Party is required to affix any seal to this Agreement or any other Loan Document pursuant to any Requirement of Law or regulation,
agrees that this Agreement is delivered by Borrower under seal and waives any shortening of the statute of limitations that may result from not affixing any seal to this Agreement or such other Loan Documents. 
 Section 10.14. Patriot Act. The Administrative Agent and each Lender hereby notifies the Loan Parties that pursuant to the
requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies each Loan Party, which information
includes the name and address of such Loan Party and other information that will allow such Lender or the Administrative Agent, as applicable, to identify such Loan Party in accordance with the Patriot Act. Each Loan Party shall, and shall cause
each of its Subsidiaries to, provide to the extent 

  

 82 

 
commercially reasonable, such information and take such other actions as are reasonably requested by the Administrative Agent or any Lender in order to
assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act. 
 Section 10.15. No General
Partner Liability. The Administrative Agent and Lenders agree for themselves and their respective successors, participants and assigns, including any subsequent holder of any Note, that any claim against Borrower which may arise under any
Loan Document shall be made only against and shall be limited to the assets of Borrower, except to the extent any general partner of the Borrower may have obligations with respect to such claim pursuant to the terms of its Guaranty Agreement, if
any, and that no judgment, order or execution entered in any suit, action or proceeding, whether legal or equitable, on this Agreement, such Note or any of the other Loan Documents shall be obtained or enforced against any general partner of the
Borrower or its assets for the purpose of obtaining satisfaction and payment of such Note, the Obligations evidenced thereby, any other Obligation or any claims arising thereunder or under this Agreement or any other Loan Document, any right to
proceed against any general partner of the Borrower individually or their respective representatives or assets being hereby expressly waived, renounced and remitted by the Administrative Agent and Lenders for themselves and their respective
successors, participants and assigns. Nothing in this Section 10.15, however, shall be construed so as to prevent the Administrative Agent, any Lender or any other holder of any Note from commencing any action, suit or proceeding with
respect to or causing legal papers to be served upon any general partner of the Borrower for the purpose of obtaining jurisdiction over Borrower. 
 Section 10.16. Amendment and Restatement. This Agreement constitutes an amendment and restatement of the Existing Credit Agreement and is not, and is not intended by the parties to be, a novation of the Existing Credit
Agreement. All rights and obligations of the parties shall continue in effect, except as otherwise expressly set forth herein. Without limiting the foregoing, no Default or Event of Default existing under the Existing Credit Agreement as of the
Restatement Date shall be deemed waived or cured by this amendment and restatement thereof. On the Restatement Date, any and all Loans outstanding under the Existing Credit Agreement, together with all accrued and unpaid interest, fees, and other
expenses and amounts payable by the Borrower under the Existing Credit Agreement, shall be paid in full to the “Lenders” under the Existing Credit Agreement, the Issuing Bank, and the Administrative Agent, and the Revolving Commitments of
those “Lenders” under the Existing Credit Agreement that are not continuing as Lenders under this Agreement shall automatically terminate and cease to be of any force or effect without further action on the part of any party. The Revolving
Commitments of the Lenders under this Agreement after giving effect to this amendment and restatement are set forth on the respective signature pages for such Lenders hereinafter set forth. On and after the Restatement Date, all Loans and other
extensions of credit shall be made by the Lenders under this Agreement in accordance with their respective Pro Rata Shares of the Revolving Commitments as in effect from time to time. All references in the other Loan Documents to the Credit
Agreement shall be deemed to refer to and mean this Amended and Restated Revolving Credit Agreement, as the same may be further amended, supplemented, and restated from time to time.

 The Debt Ratings in effect on any date is that in effect at the close of business on such date. If
the Borrower is split-rated and (1) the ratings differential is one category, the higher of the two ratings will apply (e.g., A-/Baa1 results in Level I status) (2) the ratings differential is two categories, the rating which falls between
them shall apply (e.g., A-/Baa2, then the rate would be based on Level II status) or (3) the ratings differential is more than two category, the rate shall be determined by reference to the category next above that of the lower of the two
ratings (e.g., A-/Baa3, then the rate would be based on Level III status). If the Borrower is not rated by either Moody’s or S&P, then the rate shall be established by reference to Level V. 
 If the rating system of Moody’s or S&P shall change, or if either rating agency shall cease to be in the business of rating corporate debt
obligations, the Borrower, the Lenders and the Administrative Agent shall negotiate in good faith to amend this Schedule to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of
any such amendment, the Applicable Margin and the Applicable Percentage shall be determined by reference to the rating most recently in effect prior to any such change or cessation. If after a reasonable time the parties cannot agree to a mutually
acceptable amendment, the Applicable Margin and the Applicable Percentage shall be determined by reference to Level V.

 FORM OF 
 AMENDED AND RESTATED GUARANTY AGREEMENT 
 THIS AMENDED AND RESTATED GUARANTY AGREEMENT (the “Agreement”), dated as of [March 30, 2007], by and among ONEOK PARTNERS
INTERMEDIATE LIMITED PARTNERSHIP, a Delaware limited partnership (the “Guarantor”), and ONEOK PARTNERS, L.P. (the “Borrower”) in favor of SUNTRUST BANK, a Georgia banking corporation, as administrative agent (the
“Administrative Agent”) for the several banks and other financial institutions (the “Lenders”) from time to time party to the Amended and Restated Revolving Credit Agreement, dated as of the date hereof, by and
among the Borrower, the Lenders, the Administrative Agent, and SunTrust Bank, as Issuing Bank and as Swingline Lender (as further amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”;
capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Credit Agreement). 
 WITNESSETH: 
 WHEREAS, pursuant to the Credit Agreement, the Lenders have agreed to establish a revolving credit facility in
favor of the Borrower; 
 WHEREAS, the Guarantor is a direct Subsidiary of the Borrower and will derive substantial benefit from the making
of Loans by the Lenders and the issuance of Letters of Credit by the Issuing Bank; and 
 WHEREAS, it is a condition precedent to the
obligations of the Administrative Agent, the Issuing Bank, the Swingline Lender, and the Lenders under the Credit Agreement that the Guarantor execute and deliver to the Administrative Agent this Amended and Restated Guaranty Agreement and the
Guarantor wishes to fulfill said condition precedent; 
 NOW, THEREFORE, in order to induce Lenders to extend the Loans and the Issuing Bank
to issue Letters of Credit and to make the financial accommodations as provided for in the Credit Agreement and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as
follows: 
 Section 1. Guarantee. The Guarantor unconditionally guarantees, jointly with any other guarantors from time to
time and severally, as a primary obligor and not merely as a surety, (i) the due and punctual payment of all Obligations including, without limitation, (A) the principal of and premium, if any, and interest (including interest accruing
during the pendency of any bankruptcy, insolvency, receivership or other similar proceeding, regardless of whether allowed or allowable in such proceeding) on the Loans, when and as due, whether at maturity, by acceleration, upon one or more dates
set for prepayment or otherwise, (B) each payment required to be made by the Borrower under the Credit Agreement in respect of any Letter of Credit, when and as due, including payments in respect of reimbursement or disbursements, interest
thereon and obligations to provide cash collateral, and (C) all other monetary obligations, including fees, costs, expenses and indemnities, whether primary, secondary, direct, contingent, fixed or 

  

 Exhibit D-1 

 
otherwise (including monetary obligations incurred during the pendency of any bankruptcy, insolvency, receivership or other similar proceeding, regardless of
whether allowed or allowable in such proceeding), of the Loan Parties to the Administrative Agent and the Lenders under the Credit Agreement and the other Loan Documents, (ii) the due and punctual performance of all covenants, agreements,
obligations and liabilities of the Loan Parties under or pursuant to the Credit Agreement and the other Loan Documents; and (iii) the due and punctual payment and performance of all obligations of the Borrower, monetary or otherwise, under any
Hedging Transaction relating to the Obligations entered into with a counterparty that was a Lender or an Affiliate of a Lender at the time such Hedging Transaction was entered into (all the monetary and other obligations referred to in the preceding
clauses (i) through (iii) being collectively called the “Guaranteed Obligations”). The Guarantor further agrees that the Guaranteed Obligations may be extended or renewed (but not increased), in whole or in part, without
notice to or further assent from the Guarantor, and that the Guarantor will remain bound upon its guarantee notwithstanding any extension or renewal of any Guaranteed Obligations. 
 Section 2. Obligations Not Waived. To the fullest extent permitted by applicable law, the Guarantor waives presentment or
protest to, demand of or payment from the other Loan Parties of any of the Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. To the fullest extent permitted by applicable law, the
obligations of the Guarantor hereunder shall not be affected by (i) the failure of the Administrative Agent or any Lender to assert any claim or demand or to enforce or exercise any right or remedy against the Borrower or any other guarantor
under the provisions of the Credit Agreement, any other Loan Document or otherwise, (ii) any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions of, this Agreement, any other Loan Document, any
guarantee or any other agreement, or (iii) the failure to perfect any security interest in, or the release of, any of the security held by or on behalf of the Administrative Agent or any Lender. 
 Section 3. Guarantee of Payment. The Guarantor further agrees that its guarantee constitutes a guarantee of payment when due
and not of collection, and waives any right to require that any resort be had by the Administrative Agent or any Lender to any security held for payment of the Guaranteed Obligations or to any balance of any deposit account or credit on the books of
the Administrative Agent or any Lender in favor of the Borrower or any other Person. 
 Section 4. No Discharge or
Diminishment of Guarantee. The obligations of the Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than the indefeasible payment in full in cash of the Guaranteed
Obligations), including any claim of waiver, release, surrender, alteration or compromise of any of the Guaranteed Obligations, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the
invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of the Guarantor hereunder shall not be discharged or impaired or otherwise affected by the
failure of the Administrative Agent or any Lender to assert any claim or demand or to enforce any remedy under the Credit Agreement, any other Loan Document or any other agreement, by any waiver or modification of any provision of any thereof, by
any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or omission that may or might in any manner or to any extent vary the risk of the Guarantor 

  

 Exhibit D-2 

 
or that would otherwise operate as a discharge of the Guarantor as a matter of law or equity (other than the indefeasible payment in cash of the
Obligations). 
 Section 5. Defenses of Borrower Waived. To the fullest extent permitted by applicable law, the Guarantor
waives any defense based on or arising out of any defense of any Loan Party or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of any Loan Party, other than the
final and indefeasible payment in full in cash of the Guaranteed Obligations. The Administrative Agent and the Lenders may, at their election, foreclose on any security held by one or more of them by one or more judicial or nonjudicial sales, accept
an assignment of any such security in lieu of foreclosure, compromise or adjust any part of the Guaranteed Obligations, make any other accommodation with any other Loan Party or any other guarantor, without affecting or impairing in any way the
liability of the Guarantor hereunder except to the extent the Guaranteed Obligations have been finally and indefeasibly paid in cash. Pursuant to applicable law, the Guarantor waives any defense arising out of any such election even though such
election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of the Guarantor against the Borrower or any other guarantor, as the case may be, or any security.

 Section 6. Agreement to Pay; Subordination. In furtherance of the foregoing and not in limitation of any other right
that the Administrative Agent or any Lender has at law or in equity against the Guarantor by virtue hereof, upon the failure of the Borrower or any other Loan Party to pay any Obligation when and as the same shall become due, whether at maturity, by
acceleration, after notice of prepayment or otherwise, the Guarantor hereby promises to and will forthwith pay, or cause to be paid, to the Administrative Agent for the benefit of the Lenders in cash the amount of such unpaid Obligation. Upon
payment by the Guarantor of any sums to the Administrative Agent, all rights of the Guarantor against any Loan Party arising as a result thereof by way of right of subrogation, contribution, reimbursement, indemnity or otherwise shall in all
respects be subordinate and junior in right of payment to the prior indefeasible payment in full in cash of all the Guaranteed Obligations. In addition, any indebtedness of any Loan Party now or hereafter held by the Guarantor is hereby subordinated
in right of payment to the prior payment in full in cash of the Guaranteed Obligations. If any amount shall erroneously be paid to the Guarantor on account of (i) such subrogation, contribution, reimbursement, indemnity or similar right or
(ii) any such indebtedness of any Loan Party, such amount shall be held in trust for the benefit of the Administrative Agent and the Lenders and shall forthwith be paid to the Administrative Agent to be credited against the payment of the
Guaranteed Obligations, whether matured or unmatured, in accordance with the terms of the Loan Documents; provided that payments of Indebtedness owing by any Loan Party to Guarantor at a time when there does not exist a Default or Event of Default
shall not be held in trust and paid to the Administrative Agent. 
 Section 7. Information. The Guarantor assumes all
responsibility for being and keeping itself informed of other Loan Parties’ financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations and the nature, scope and extent of the
risks that the Guarantor assumes and incurs hereunder, and agrees that none of the Administrative Agent or the Lenders will have any duty to advise the Guarantor of information known to it or any of them regarding such circumstances or risks.

  

 Exhibit D-3 

 Section 8. Indemnity and Subrogation. In addition to all such rights of indemnity and
subrogation as the Guarantor may have under applicable law (but subject to Section 6), the Borrower agrees that (a) in the event a payment shall be made by the Guarantor under this Agreement, the Borrower shall indemnify the Guarantor for
the full amount of such payment and the Guarantor shall be subrogated to the rights of the person to whom such payment shall have been made to the extent of such payment and (b) in the event any assets of the Guarantor shall be sold to satisfy
a claim of any Lender under this Agreement, the Borrower shall indemnify the Guarantor in an amount equal to the greater of the book value or the fair market value of the assets so sold. 
 Section 9. Reserved 
 Section 10. Subordination. Notwithstanding any provision of this Agreement to the contrary, all rights of the Guarantor under Section 8 and all other rights of indemnity, contribution or subrogation under applicable
law or otherwise shall be fully subordinated to the indefeasible payment in full in cash of the Guaranteed Obligations. No failure on the part of the Borrower to make the payments required under applicable law or otherwise shall in any respect limit
the obligations and liabilities of the Guarantor with respect to its obligations hereunder, and the Guarantor shall remain liable for the full amount of the obligations of the Guarantor hereunder. 
 Section 11. Representations and Warranties. The Guarantor represents and warrants as to itself that all representations and warranties
relating to it (as a Subsidiary of the Borrower) contained in the Credit Agreement are true and correct. 
 Section 12.
Termination. The guarantees made hereunder (i) shall terminate when all the Guaranteed Obligations have been paid in full in cash and the Lenders have no further commitment to lend under the Credit Agreement, the LC Exposure has been
reduced to zero and the Issuing Bank has no further obligation to issue Letters of Credit under the Credit Agreement and (ii) shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of
any Obligation is rescinded or must otherwise be restored by any Lender or the Guarantor upon the bankruptcy or reorganization of the Borrower, the Guarantor or otherwise. In connection with the foregoing, the Administrative Agent shall execute and
deliver to the Guarantor or its designee, at the Guarantor’s expense, any documents or instruments which the Guarantor shall reasonably request from time to time to evidence such termination and release. 
 Section 13. Binding Effect; Several Agreement; Assignments. Whenever in this Agreement any of the parties hereto is referred to, such
reference shall be deemed to include the successors and assigns of such party; and all covenants, promises and agreements by or on behalf of the Guarantor that are contained in this Agreement shall bind and inure to the benefit of each party hereto
and their respective successors and assigns. This Agreement shall become effective as to the Guarantor when a counterpart hereof executed on behalf of the Guarantor shall have been delivered to the Administrative Agent, and a counterpart hereof
shall have been executed on behalf of the Administrative Agent, and thereafter shall be binding upon the Guarantor and the Administrative Agent and their respective successors and assigns, and shall inure to the benefit of the Guarantor, the
Administrative Agent and the Lenders, and their respective 

  

 Exhibit D-4 

 
successors and assigns, except that Guarantor shall not have the right to assign its rights or obligations hereunder or any interest herein (and any such
attempted assignment shall be void). 
 Section 14. Waivers; Amendment. 
 (a) No failure or delay of the Administrative Agent of any kind in exercising any power or right hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and of
the Administrative Agent hereunder and of the Lenders under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any
departure by the Guarantor therefrom shall in any event be effective unless the same shall be permitted by subsection (b) below, and then such waiver and consent shall be effective only in the specific instance and for the purpose for which
given. No notice or demand on the Guarantor in any case shall entitle the Guarantor to any other or further notice in similar or other circumstances. 
 (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to a written agreement entered into between the Guarantor with respect to which such waiver, amendment or
modification relates and the Administrative Agent, with the prior written consent of the Required Lenders (except as otherwise provided in the Credit Agreement). 
 Section 15. Notices. All communications and notices hereunder shall be in writing and given as provided in Section 10.1 of the Credit Agreement. All communications and notices hereunder to the
Guarantor shall be given to it at its address set forth on Schedule I attached hereto. 
 Section 16. Severability. Any
provision of this Agreement held to be illegal, invalid or unenforceable in any jurisdiction, shall, as to such jurisdiction, be ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or
enforceability of the remaining provisions hereof or thereof; and the illegality, invalidity or unenforceability of a particular provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other
jurisdiction. 
 Section 17. Counterparts; Integration. This Agreement may be executed in counterparts, each of which
shall constitute an original, but all of which when taken together shall constitute a single contract (subject to Section 13), and shall become effective as provided in Section 13. Delivery of an executed signature page to this Agreement
by facsimile transmission shall be as effective as delivery of a manually executed counterpart of this Agreement. This Agreement constitutes the entire agreement among the parties hereto regarding the subject matters hereof and supersedes all prior
agreements and understandings, oral or written, regarding such subject matter. 
 Section 18. Rules of Interpretation. The
rules of interpretation specified in Section 1.4 of the Credit Agreement shall be applicable to this Agreement. 
  

 Exhibit D-5 

 Section 19. Governing Law; Jurisdiction; Consent to Service of Process.

 (a) This Agreement shall be construed in accordance with and be governed by the law (without giving effect to the conflict of law
principles thereof) of the State of New York. 
 (b) The Guarantor hereby irrevocably and unconditionally submits, for itself and its
property, to the non-exclusive jurisdiction of the United States courts located within the Southern district in the State of New York, and of any state court of the State of New York located in New York County and any appellate court from any
thereof, in any action or proceeding arising out of or relating to this Agreement or any other Loan Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby
irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the extent permitted by applicable law, such Federal court. The Guarantor agrees that
a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that the Administrative
Agent, the Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement against the Guarantor or its properties in the courts of any jurisdiction. 
 (c) The Guarantor irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such suit, action
or proceeding described in paragraph (b) of this Section and brought in any court referred to in paragraph (b) of this Section. Each party hereto irrevocably waives, to the fullest extent permitted by applicable law, the defense of an
inconvenient forum to the maintenance of such action or proceeding in any such court. 
 (d) The Guarantor irrevocably consents to the
service of process in the manner provided for notices in Section 10.1 of the Credit Agreement. Nothing in this Agreement will affect the right of the Administrative Agent or any Lender to serve process in any other manner permitted by law.

 Section 20. Waiver of Jury Trial. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER THEORY). EACH PARTY HERETO (i) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER, AND (ii) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 
  

 Exhibit D-6 

 Section 21. Right of Setoff. If an Event of Default shall have occurred and be
continuing, each 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 to or for the credit or the account of the Guarantor against any or all the obligations of the Guarantor now or hereafter existing under this Agreement and the other Loan Documents held by such Lender,
irrespective of whether or not such Person shall have made any demand under this Agreement or any other Loan Document and although such obligations may be unmatured. The rights of each Lender under this Section 21 are in addition to
other rights and remedies (including other rights of setoff) that such Lender may have. 
 Section 22. Savings
Clause. 
 (a) It is the intent of the Guarantor and the Administrative Agent that the Guarantor’s maximum obligations hereunder
shall be, but not in excess of: 
 (i) in a case or proceeding commenced by or against the Guarantor under the provisions of
Title 11 of the United States Code, 11 U.S.C. §§101 et seq. (the “Bankruptcy Code”) on or within one year from the date on which any of the Guaranteed Obligations are incurred, the maximum amount which would not
otherwise cause the Guaranteed Obligations (or any other obligations of the Guarantor owed to the Administrative Agent or the Lenders) to be avoidable or unenforceable against the Guarantor under (i) Section 548 of the Bankruptcy Code or
(ii) any state fraudulent transfer or fraudulent conveyance act or statute applied in such case or proceeding by virtue of Section 544 of the Bankruptcy Code; or 
 (ii) in a case or proceeding commenced by or against the Guarantor under the Bankruptcy Code subsequent to one year from the date on which
any of the Guaranteed Obligations are incurred, the maximum amount which would not otherwise cause the Guaranteed Obligations (or any other obligations of the Guarantor to the Administrative Agent or the Lenders) to be avoidable or unenforceable
against the Guarantor under any state fraudulent transfer or fraudulent conveyance act or statute applied in any such case or proceeding by virtue of Section 544 of the Bankruptcy Code; or 
 (iii) in a case or proceeding commenced by or against the Guarantor under any law, statute or regulation other than the Bankruptcy Code
(including, without limitation, any other bankruptcy, reorganization, arrangement, moratorium, readjustment of debt, dissolution, liquidation or similar debtor relief laws), the maximum amount which would not otherwise cause the Guaranteed
Obligations (or any other obligations of the Guarantor to the Administrative Agent or the Lenders) to be avoidable or unenforceable against the Guarantor under such law, statute or regulation including, without limitation, any state fraudulent
transfer or fraudulent conveyance act or statute applied in any such case or proceeding. 
 (b) The substantive laws under which the possible
avoidance or unenforceability of the Guaranteed Obligations (or any other obligations of the Guarantor to the Administrative Agent or the Lenders) as may be determined in any case or proceeding shall hereinafter be 

  

 Exhibit D-7 

 
referred to as the “Avoidance Provisions.” To the extent set forth in Section 22(a)(i), (ii), and (iii), but only
to the extent that the Guaranteed Obligations would otherwise be subject to avoidance or found unenforceable under the Avoidance Provisions, if the Guarantor is not deemed to have received valuable consideration, fair value or reasonably equivalent
value for the Guaranteed Obligations, or if the Guaranteed Obligations would render the Guarantor insolvent, or leave the Guarantor with an unreasonably small capital to conduct its business, or cause the Guarantor to have incurred debts (or to have
intended to have incurred debts) beyond its ability to pay such debts as they mature, in each case as of the time any of the Guaranteed Obligations are deemed to have been incurred under the Avoidance Provisions and after giving effect to the
contribution by the Guarantor, the maximum Guaranteed Obligations for which the Guarantor shall be liable hereunder shall be reduced to that amount which, after giving effect thereto, would not cause the Guaranteed Obligations (or any other
obligations of the Guarantor to the Administrative Agent or the Lenders), as so reduced, to be subject to avoidance or unenforceability under the Avoidance Provisions. 
 (c) This Section 22 is intended solely to preserve the rights of the Administrative Agent and the Lenders hereunder to the maximum extent that would not cause the Guaranteed Obligations of the Guarantor to
be subject to avoidance or unenforceability under the Avoidance Provisions, and neither the Guarantor nor any other Person shall have any right or claim under this Section 22 as against the Administrative Agent or Lenders that would not
otherwise be available to such Person under the Avoidance Provisions. 
 Section 23. NO GENERAL PARTNERS’
LIABILITY. By their acceptance of this Agreement, the Administrative Agent and the Lenders agree for themselves and their respective successors, participants and assigns, including any subsequent holder of any Note, that any claim against
Guarantor which may arise under this Agreement shall be made only against and shall be limited to the assets of Guarantor, and that no judgment, order or execution entered in any suit, action or proceeding, whether legal or equitable, on this
Agreement shall be obtained or enforced against any general partner of Guarantor (individually, a “General Partner,” and collectively, “General Partners”) or its or their assets for the purpose of
obtaining satisfaction and payment of this Agreement, the Guaranteed Debt, any other Obligation or any claims arising hereunder, any right to proceed against the General Partners individually or their respective representatives or assets being
hereby expressly waived, renounced and remitted by the Administrative Agent and the Lenders for themselves and their respective successors, participants and assigns. Nothing in this Section 23, however, shall be construed so as to
prevent the Administrative Agent, any Lender or any other holder of any Note from commencing any action, suit or proceeding with respect to or causing legal papers to be served upon any General Partner for the purpose of obtaining jurisdiction over
Guarantor. 
 Section 24. Amendment and Restatement. This Agreement constitutes an amendment and restatement of the
Amended and Restated Guaranty Agreement dated as of March 30, 2006 in favor of the Administrative Agent (the “Existing Guaranty Agreement”) and is not, and is not intended by the parties to be, a novation of the Existing Guaranty
Agreement. All rights and obligations of the parties shall continue in effect, except as otherwise expressly set forth herein. All references in the Loan Documents to the Guaranty Agreement shall be deemed to refer to and mean this Amended and
Restated Guaranty Agreement, as the same may be further amended, supplemented, and restated from time to time.
