Islands Branch (“CS”), as administrative agent for the Lenders (in such capacity, the “Agent”) and as a fronting bank for letters of credit issued hereunder, and Lehman Brothers Bank, as a fronting
bank for letters of credit issued hereunder. 
 WITNESSETH: 
 WHEREAS, the Borrower has requested that the Lenders and the Fronting Banks provide the revolving credit and letter of credit facilities hereinafter described in the amounts and on the terms and conditions set forth
herein; and 
 WHEREAS, the Lenders and the Fronting Banks have agreed to provide such facilities on the terms and conditions set forth
herein, and CS has agreed to act as Agent on behalf of the Lenders and the Fronting Banks on such terms and conditions. 
 NOW, THEREFORE,
the parties hereto agree as follows: 
 ARTICLE I 
 DEFINITIONS; CONSTRUCTION 
 SECTION 1.01. Defined Terms. 
 As used in this Agreement, the following terms shall have the meanings specified below: 
 “ABR Borrowing” shall mean a Borrowing comprised of ABR Loans. 
 “ABR Loan” shall mean any Loan bearing interest at a rate determined by reference to the Alternate Base Rate in
accordance with the provisions of Article II or any Eurodollar Loan converted (pursuant to Section 2.03, 2.07 or 2.11(a)(ii)) to a loan bearing interest at a rate determined by reference to the Alternate Base Rate. 
 “Acquisition Date” shall mean the date as of which a person or group of related persons first acquires more than
30% of any outstanding class of Voting Shares of TXU (within the meaning of Section 13(d) or 14(d) of the Exchange Act, and the applicable rules and regulations thereunder). 
 “Administrative Fees” shall have the meaning assigned to such term in Section 2.04(c). 
 “Affiliate” shall mean, when used with respect to a specified person, another person that directly or indirectly
controls or is controlled by or is under common control with the person specified. 







 “Agent” shall have the meaning given such term in the preamble
hereto. 
 “Agreement” shall have the meaning given such term in the preamble hereto. 
 “Alternate Base Rate” shall mean, for any day, a rate per annum (rounded upwards, if necessary, to the next
1/16 of 1%) equal to the greater of (i) the Federal Funds Effective Rate in effect on such day plus 1/2 of 1% and (ii) the Prime Rate in effect on such day. For purposes hereof, “Prime Rate” shall mean the rate of interest

quotations for the day of such transactions received by CS from three Federal funds brokers of recognized standing selected by it. If for any reason CS shall have determined (which determination shall be conclusive absent manifest error;
provided that CS shall, upon request, provide to the Borrower a certificate setting forth in reasonable detail the basis for such determination) that it is unable to ascertain the Federal Funds Effective Rate for any reason, including the
inability of CS to obtain sufficient quotations in accordance with the terms thereof, the Alternate Base Rate shall be determined without regard to clause (i) of the first sentence of this definition until the circumstances giving rise to such
inability no longer exist. Any change in the Alternate Base Rate due to a change in the Prime Rate or the Federal Funds Effective Rate shall be effective on the effective date of such change in the Prime Rate or the Federal Funds Effective Rate,
respectively. 
 “Applicable Margin” shall mean, for any ABR Loan 0% per annum and for any
Eurodollar Loan 0.375% per annum, provided, however, at any time an Event of Default has occurred and is continuing, the Applicable Margins shall be increased by 2.00%. 
 “Applicable Rating Level” shall mean the level set forth below in the row next to the then applicable Debt
Ratings. If there is a difference of one level in the Debt Ratings, then the higher Debt Rating shall be used for purposes of determining the Applicable Rating Level, and if there is a difference of more than one level in the Debt Ratings, then the
Debt Rating one level higher than the lower Debt Rating will be used for purposes of determining the Applicable Rating Level. Any change in the Applicable Rating Level shall be effective on the date on which the applicable rating agency announces
any change in the applicable Debt Rating.

 ARTICLE II 
 THE CREDITS

 SECTION 2.01. Commitments. 
 (a) Subject to the terms and conditions and relying upon the representations and warranties herein set forth, each Lender and each Fronting Bank (as applicable) agrees, severally and not jointly, as follows: (i) each
Lender agrees to make Loans to the Borrower at any time and from time to time until the Commitment Termination Date up to the amount of such Lender’s Available Commitment, (ii) each Fronting Bank agrees to issue Letters of Credit for the
account of the Borrower at any time and from time to time until the fifth Business Day preceding the Commitment Termination Date in an aggregate stated amount at any time outstanding not to exceed such Fronting Bank’s LC Fronting Bank
Commitment, and (iii) each Lender agrees to purchase participations in such Letters of Credit as more fully set forth in Section 2.17. Notwithstanding the foregoing, at no time shall (A) the aggregate amount of Outstanding Credits exceed the
aggregate amount of the Lenders’ Commitments, (B) any Lender’s Outstanding Credits exceed the amount of such Lender’s Commitment and (C) any Fronting Bank make any Extension of Credit relating to a Letter of Credit if such Extension
of Credit would cause (x) the aggregate amount of Outstanding Credits to exceed the aggregate amount of the Lenders’ Commitments or (y) the aggregate LC Outstandings relating to such Fronting Bank to exceed such Fronting Bank’s LC Fronting
Bank Commitment. 
 (b) Within the foregoing limits, the Borrower may borrow, pay or prepay Loans and request new Extensions of Credit on and
after the date hereof and prior to the Commitment Termination Date subject to the terms, conditions and limitations set forth herein. 
 SECTION 2.02. Loans. 
 (a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders
ratably in accordance with their respective Commitments; provided, however, that the failure of any Lender to make any Loan shall not in itself relieve any other Lender of its obligation to lend hereunder (it being understood, however, that
no Lender shall be responsible for the failure of any other Lender to make any Loan required to be made by such other Lender). The Loans comprising any Borrowing shall be in an aggregate principal amount that is an integral multiple of $5,000,000
and not less than $25,000,000 (or an aggregate principal amount equal to the remaining balance of the Available Commitments). 
 (b) Each
Borrowing shall be comprised entirely of Eurodollar Loans or ABR Loans, as the Borrower may request pursuant to Section 2.03. Each Lender may at its option make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such
Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. Borrowings of more than one Type may be outstanding at the
same time. 
  

 16 








 (c) Subject to subsection (d) below, each Lender shall make each Loan to be made by it hereunder on the
proposed date thereof by wire transfer of immediately available funds to the Agent in New York, New York, not later than noon, New York City time, and the Agent shall by 2:00 p.m., New York City time, credit the amounts so received to the account or
accounts specified from time to time in one or more notices delivered by the Borrower to the Agent or, if a Borrowing shall not occur on such date because any condition precedent herein specified shall not have been met, return the amounts so
received to the respective Lenders. Loans shall be made by the Lenders pro rata in accordance with Section 2.12. Unless the Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make
available to the Agent such Lender’s portion of such Borrowing, the Agent may assume that such Lender has made such portion available to the Agent on the date of such Borrowing in accordance with this subsection (c) and the Agent may, in
reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have made such portion available to the Agent, such Lender and the Borrower (without waiving any claim
against such Lender for such Lender’s failure to make such portion available) severally agree to repay to the Agent forthwith on demand such corresponding amount together with interest thereon, for each day from the date such amount is made
available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds
Effective Rate. If such Lender shall repay to the Agent such corresponding amount, such amount shall constitute such Lender’s Loan as part of such Borrowing for purposes of this Agreement. 
 (d) The Borrower may refinance all or any part of any Borrowing with a Borrowing of the same or a different Type, subject to the conditions and
limitations set forth in this Agreement. Any Borrowing or part thereof so refinanced shall be deemed to be repaid or prepaid in accordance with Section 2.05 or 2.09, as applicable, with the proceeds of a new Borrowing, and the proceeds of the new
Borrowing, to the extent they do not exceed the principal amount of the Borrowing being refinanced, shall not be paid by the Lenders to the Agent or by the Agent to the Borrower pursuant to subsection (c) above. 
 SECTION 2.03. Borrowing Procedure. 
 In order to request a Borrowing, the Borrower shall hand deliver or send via facsimile to the Agent a duly completed Borrowing Request (i) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., New York City time, three Business
Days before such Borrowing, and (ii) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, one Business Day before such Borrowing. Such notice shall be irrevocable and shall in each case specify (A) whether the Borrowing
then being requested is to be a Eurodollar Borrowing or an ABR Borrowing, (B) the date of such Borrowing (which shall be a Business Day) and the amount thereof, (C) if such Borrowing is to be a Eurodollar Borrowing, the Interest Period with respect
thereto, which shall not end after the Commitment Termination Date, and (D) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of this Agreement. If no election as to
the Type of Borrowing is 
  

 17 








 specified in any such notice, then the requested Borrowing shall be deemed an ABR Borrowing. If no Interest Period with
respect to any Eurodollar Borrowing is specified in any such notice, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration (subject to the limitations set forth in the definition of “Interest
Period”). If the Borrower shall not have given notice in accordance with this Section of its election to refinance a Borrowing prior to the end of the Interest Period in effect for such Borrowing, then the Borrower shall (unless such Borrowing
is repaid at the end of such Interest Period) be deemed to have given notice of an election to refinance such Borrowing with an ABR Borrowing. Notwithstanding any other provision of this Agreement to the contrary, no Borrowing shall be requested if
the Interest Period with respect thereto would end after the Commitment Termination Date. The Agent shall promptly advise the Lenders of any notice given pursuant to this Section and of each Lender’s portion of the requested Borrowing.

 SECTION 2.04. Fees. 
 (a) The Borrower agrees to pay to each Lender, through the Agent, on each March 31, June 30, September 30 and December 31 (with the first payment being due on June 30, 2006) and on each date on which the Commitment of such Lender shall be
terminated or reduced as provided herein, a commitment fee (a “Commitment Fee”), at a rate per annum equal to the Commitment Fee Percentage on the unused portion of the Commitment of such Lender during the preceding
quarter (or other period commencing on the date of this Agreement or ending on the Commitment Termination Date or any date on which the Commitment of such Lender shall be terminated). 
 (b) All Commitment Fees shall be computed on the basis of the actual number of days elapsed in a year of 360 days. The Commitment Fee due to each Lender
shall commence to accrue on the date of this Agreement, and shall cease to accrue on the date of termination of the Commitment of such Lender as provided herein. 
 (c) The Borrower agrees to pay the Agent the fees from time to time payable to it in its capacity as Agent pursuant to the Letter Agreements (the “Administrative Fees”). 
 (d) The Borrower agrees to pay the Agent, for the account of the Fronting Bank that issued any Letter of Credit, a fronting fee equal to 0.125% of the
stated amount of such Letter of Credit (a “Fronting Fee”) and such other charges with respect to such Letter of Credit as are agreed upon with such Fronting Bank and as are customary. The Borrower agrees to pay to the Agent for the account
of the Lenders a fee (the “LC Fee”) on the face amount of each Letter of Credit issued by any Fronting Bank, calculated at a rate per annum equal to the Applicable Margin for Eurodollar Loans (regardless of whether any such Loans
are then outstanding). All Fronting Fees and LC Fees shall be computed on the basis of the actual number of days that each such Letter of Credit is outstanding, assuming a year of 360 days, payable in arrears on each March 31, June 30, September 30
and December 31, and on the date that such Letter of Credit expires or is drawn in full. 
 (e) All Fees shall be paid on the dates due, in
immediately available funds, to the Agent for distribution, if and as appropriate, among the Lenders. Once paid, none of the Fees shall be refundable under any circumstances. 
  

 18 








 SECTION 2.05. Repayment of Loans; Evidence of Indebtedness. 
 (a) The outstanding principal balance of each (i) Eurodollar Loan shall be due and payable on the last day of the Interest Period applicable thereto and
on the Commitment Termination Date and (ii) ABR Loan shall be due and payable on the Commitment Termination Date. 
 (b) Each Lender shall
maintain in accordance with its usual practice an account or accounts evidencing the indebtedness to such Lender resulting from each Extension of Credit made by such Lender from time to time, including the amounts of principal and interest payable
and paid to such Lender from time to time under this Agreement. 
 (c) The Agent shall maintain accounts in which it will record (i) the
amount of each Extension of Credit made hereunder, the Type of each Loan made and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Agent hereunder from the Borrower and each Lender’s share thereof. 
 (d) The
entries made in the accounts maintained pursuant to subsections (b) and (c) above shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however,
that the failure of any Lender or the Agent to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrower to repay the Outstanding Credits in accordance with their terms. 
 SECTION 2.06. Interest on Loans. 
 (a) The Loans comprising each Eurodollar Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 360 days) at a rate per annum equal to the LIBO Rate for the Interest Period in effect
for such Borrowing plus the Applicable Margin from time to time in effect for Eurodollar Borrowings. 
 (b) The Loans comprising each ABR
Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of (i) 365 or 366 days, as the case may be, for periods during which the Alternate Base Rate is determined by reference to the Prime Rate and (ii)
360 days for other periods) at a rate per annum equal to the Alternate Base Rate plus the Applicable Margin from time to time in effect for ABR Borrowings. 
 (c) Interest on each Loan shall be payable on each Interest Payment Date applicable to such Loan except as otherwise provided in this Agreement. The applicable LIBO Rate or Alternate Base Rate for each Interest Period
or day within an Interest Period, as the case may be, shall be determined by CS, and such determination shall be conclusive absent manifest error; provided that CS shall, upon request, provide to the Borrower a certificate setting forth in
reasonable detail the basis for such determination. 
  

 19 








 SECTION 2.07. Alternate Rate of Interest. 
 In the event, and on each occasion, that on the day two Business Days prior to the commencement of any Interest Period for a Eurodollar Borrowing the
Agent shall have determined (i) that dollar deposits in the principal amounts of the Eurodollar Loans comprising such Borrowing are not generally available in the London interbank market or (ii) that reasonable means do not exist for ascertaining
the LIBO Rate, the Agent shall, as soon as practicable thereafter, give facsimile notice of such determination to the Borrower and the Lenders. In the event of any such determination under clause (i) or (ii) above, until the Agent shall have advised
the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, any request by the Borrower for a Eurodollar Borrowing pursuant to Section 2.03 shall be deemed to be a request for an ABR Borrowing. In the event the
Required Lenders notify the Agent that the rates at which dollar deposits are being offered will not adequately and fairly reflect the cost to such Lenders of making or maintaining Eurodollar Loans during such Interest Period, the Agent shall notify
the Borrower of such notice and until the Required Lenders shall have advised the Agent that the circumstances giving rise to such notice no longer exist, any request by the Borrower for a Eurodollar Borrowing shall be deemed a request for an ABR
Borrowing. Each determination by the Agent hereunder shall be made in good faith and shall be conclusive absent manifest error; provided that the Agent, shall, upon request, provide to the Borrower a certificate setting forth in reasonable
detail the basis for such determination. 
 SECTION 2.08. Termination and Reduction of Commitments. 
 (a) The Commitments shall terminate automatically on the Commitment Termination Date. 
 (b) Upon at least two Business Days’ prior irrevocable written notice to the Agent, the Borrower may, without premium or penalty, at any time in
whole permanently terminate, or from time to time in part permanently reduce, the Commitments; provided, however, that (i) each partial reduction of the Commitments shall be in an integral multiple of $10,000,000 and in a minimum principal
amount of $10,000,000 and (ii) no such termination or reduction shall be made that would reduce the Commitments to an amount less than (1) the aggregate amount of Outstanding Credits on the date of such termination or reduction (after giving effect
to any prepayment made pursuant to Section 2.09) or (2) $50,000,000, unless the result of such termination or reduction referred to in this clause (2) is to reduce the Commitments to $0. The Agent shall advise the Lenders of any notice given
pursuant to this subsection (b) and of each Lender’s portion of any such termination or reduction of the Commitments. 
 (c) Each
reduction in the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments. The Borrower shall pay to the Agent for the account of the Lenders, on the date of each termination or reduction of the
Commitments, the Commitment Fee on the amount of the Commitments so terminated or reduced, in each case accrued through the date of such termination or reduction. 
  

 20 








 SECTION 2.09. Prepayment. 
 The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, upon giving a written notice
substantially in the form of Exhibit C (a “Prepayment Notice”) via facsimile (or telephone notice promptly confirmed by facsimile) to the Agent: (i) before 11:00 a.m., New York City time, three Business Days prior to
prepayment, in the case of Eurodollar Loans, and (ii) before 11:00 a.m., New York City time, one Business Day prior to prepayment, in the case of ABR Loans; provided, however, that each partial prepayment shall be in an amount which is an
integral multiple of $10,000,000 and not less than $10,000,000. Each Prepayment Notice shall specify the prepayment date and the principal amount of each Borrowing (or portion thereof) to be prepaid, shall be irrevocable and shall commit the
Borrower to prepay such Borrowing (or portion thereof) by the amount stated therein on the date stated therein. All prepayments under this Section shall be subject to Section 8.05 but otherwise without premium or penalty. All prepayments under this
Section shall be accompanied by accrued interest on the principal amount being prepaid to the date of payment. 
 SECTION 2.10. Reserve
Requirements; Change in Circumstances. 
 (a) Notwithstanding any other provision herein, if after the date of this Agreement any
change in applicable law or regulation or in the interpretation or administration thereof by any Governmental Authority charged with the interpretation or administration thereof (whether or not having the force of law) shall change the basis of
taxation of payments to any Lender or any Fronting Bank hereunder (except for changes in respect of taxes on the overall net income of such Lender or such Fronting Bank (as the case may be) or its lending office imposed by the jurisdiction in which
such Lender’s or such Fronting Bank’s (as the case may be) principal executive office or lending office is located), or shall result in the imposition, modification or applicability of any reserve, special deposit or similar requirement
against assets of, deposits with or for the account of or credit extended by any Lender or such Fronting Bank (as the case may be) or shall result in the imposition on any Lender, any Fronting Bank or the London interbank market of any other
condition affecting this Agreement, such Lender’s Commitment or any Extension of Credit (other than an ABR Loan) made by such Lender or such Fronting Bank, and the result of any of the foregoing shall be to increase the cost to such Lender or
such Fronting Bank (as the case may be) of making or maintaining any Outstanding Credit (other than an ABR Loan) or to reduce the amount of any sum received or receivable by such Lender or such Fronting Bank (as the case may be) hereunder (whether
of principal, interest or otherwise) by an amount deemed by such Lender or such Fronting Bank (as the case may be) to be material, then the Borrower shall, upon receipt of the notice and certificate provided for in subsection (c) below promptly pay
to such Lender or such Fronting Bank (as the case may be) such additional amount or amounts as will compensate such Lender or such Fronting Bank (as the case may be) for such additional costs incurred or reduction suffered. 
 (b) If any Lender or Fronting Bank shall have determined that the adoption of any law, rule, regulation or guideline arising out of the July 1988 report
of the Basle Committee on Banking Regulations and Supervisory Practices entitled “International Convergence of Capital Measurement and Capital Standards,” or the adoption after the date hereof of any other law, rule, regulation or
guideline regarding capital adequacy, or any change in any of the foregoing or in 
  

 21 








 the interpretation or administration of any of the foregoing by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance by any Lender or Fronting Bank (or any lending office of such Lender or such Fronting Bank) or any Lender’s or any Fronting Bank’s holding company with any
request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Lender’s or such Fronting
Bank’s (as the case may be) capital or on the capital of such Lender’s or such Fronting Bank’s (as the case may be) holding company, if any, as a consequence of this Agreement, such Lender’s Commitment or the Extensions of Credit
made by such Lender or such Fronting Bank (as the case may be) pursuant hereto to a level below that which such Lender or such Fronting Bank (as the case may be) or such Lender’s or such Fronting Bank’s (as the case may be) holding company
could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such Fronting Bank’s (as the case may be) policies and the policies of such Lender’s or such Fronting Bank’s (as the case
may be) holding company with respect to capital adequacy) by an amount deemed by such Lender or such Fronting Bank (as the case may be) to be material, then from time to time such additional amount or amounts as will compensate such Lender or such
Fronting Bank (as the case may be) for any such reduction suffered will be paid to such Lender or such Fronting Bank (as the case may be) by the Borrower. It is acknowledged that this Agreement is being entered into by the Lenders and the Fronting
Banks on the understanding that neither the Lenders nor the Fronting Banks will be required to maintain capital against their Commitments or agreements to issue Letters of Credit, as the case may be, under currently applicable laws, regulations and
regulatory guidelines. In the event the Lenders or the Fronting Banks shall otherwise determine that such understanding is incorrect, it is agreed that the Lenders or the Fronting Banks, as the case may be, will be entitled to make claims under this
subsection (b) based upon market requirements prevailing on the date hereof for commitments under comparable credit facilities against which capital is required to be maintained. 
 (c) A certificate of each Lender or the applicable Fronting Bank setting forth such amount or amounts as shall be necessary to compensate such Lender or
such Fronting Bank (as the case may be) or its holding company as specified in subsection (a) or (b) above, as the case may be, and containing an explanation in reasonable detail of the manner in which such amount or amounts shall have been
determined, shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay each Lender or Fronting Bank (as the case may be) the amount shown as due on any such certificate delivered by it within 10 days
after its receipt of the same. Each Lender and each Fronting Bank shall give prompt notice to the Borrower of any event of which it has knowledge, occurring after the date hereof, that it has determined will require compensation by the Borrower
pursuant to this Section; provided, however, that failure by such Lender or such Fronting Bank to give such notice shall not constitute a waiver of such Lender’s or such Fronting Bank’s (as the case may be) right to demand
compensation hereunder. 
 (d) Failure on the part of any Lender or Fronting Bank to demand compensation for any increased costs or reduction
in amounts received or receivable or reduction in return on capital with respect to any period shall not constitute a waiver of such Lender’s or such Fronting Bank’s (as the case may be) right to demand compensation with respect to such
period or any other period; provided, however, that no Lender or Fronting Bank shall be entitled to compensation 
  

 22 








 under this Section for any costs incurred or reductions suffered with respect to any date unless it shall have notified
the Borrower that it will demand compensation for such costs or reductions under subsection (c) above not more than 90 days after the later of (i) such date and (ii) the date on which it shall have become aware of such costs or reductions. The
protection of this Section shall be available to each Lender and each Fronting Bank regardless of any possible contention of the invalidity or inapplicability of the law, rule, regulation, guideline or other change or condition which shall have
occurred or been imposed. 
 (e) Each Lender and each Fronting Bank agrees that it will designate a different lending office if such
designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Lender or such Fronting Bank (as the case may be) be disadvantageous to such Lender or Fronting Bank (as the case may
be). 
 SECTION 2.11. Change in Legality. 
 (a) Notwithstanding any other provision herein, if any change in any law or regulation or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall
make it unlawful for any Lender to make or maintain any Eurodollar Loan or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Loan, then, by written notice to the Borrower and to the Agent, such Lender may:

 (i) declare that Eurodollar Loans will not thereafter be made by such Lender hereunder, whereupon any request for a
Eurodollar Borrowing shall, as to such Lender only, be deemed a request for an ABR Loan unless such declaration shall be subsequently withdrawn (any Lender delivering such a declaration hereby agreeing to withdraw such declaration promptly upon
determining that such event of illegality no longer exists); and 
 (ii) require that all outstanding Eurodollar Loans made by
it be converted to ABR Loans, in which event all such Eurodollar Loans shall be automatically converted to ABR Loans as of the effective date of such notice as provided in subsection (b) below. 
 In the event any Lender shall exercise its rights under (i) or (ii) above, all payments and prepayments of principal which would otherwise have been applied to repay the
Eurodollar Loans that would have been made by such Lender or the converted Eurodollar Loans of such Lender shall instead be applied to repay the ABR Loans made by such Lender in lieu of, or resulting from the conversion of, such Eurodollar Loans.

 (b) For purposes of this Section, a notice by any Lender shall be effective as to each Eurodollar Loan, if lawful, on the last day of the
Interest Period currently applicable to such Eurodollar Loan; in all other cases such notice shall be effective on the date of receipt. 
 SECTION 2.12. Pro Rata Treatment. 
 Except as required under Sections 2.10 and 2.15, each Borrowing, each payment or
prepayment of principal of any Borrowing, each payment of interest on the Loans, each payment of a reimbursement obligation in respect of a drawn Letter of Credit, each payment of the Commitment Fees, each reduction of the Total Commitment and each
refinancing or conversion of any Borrowing with a Borrowing of any Type, shall be allocated pro rata among the Lenders 
  

 23 








 in accordance with their respective Commitments (or, if such Commitments shall have expired or been terminated, in
accordance with the respective principal amounts of their Outstanding Credits). For purposes of determining the Available Commitments of the Lenders at any time, the LC Outstandings shall be deemed to have utilized the Commitments of the Lenders
pro rata in accordance with their respective Commitments at such time. Each Lender agrees that in computing such Lender’s portion of any Borrowing to be made hereunder, the Agent may, in its discretion, round each Lender’s
percentage of such Borrowing to the next higher or lower whole dollar amount. 
 SECTION 2.13. Sharing of Setoffs. 

Each Lender agrees that if it shall, through the exercise of a right of banker’s lien, setoff or counterclaim, or pursuant to a secured claim
under Section 506 of Title 11 of the United States Bankruptcy Code or other security or interest arising from, or in lieu of, such secured claim, received by such Lender under any applicable bankruptcy, insolvency or other similar law or otherwise,
or by any other means, obtain payment (voluntary or involuntary) in respect of any Loans or LC Outstandings as a result of which the unpaid principal portion of its Loans and LC Outstandings shall be proportionately less than the unpaid principal
portion of the Loans and LC Outstandings of any other Lender, it shall be deemed simultaneously to have purchased from such other Lender at face value, and shall promptly pay to such other Lender the purchase price for, a participation in the Loans
or LC Outstandings of such other Lender, so that the aggregate unpaid principal amount of the Loans and LC Outstandings and participations in the Loans and LC Outstandings held by each Lender shall be in the same proportion to the aggregate unpaid
principal amount of all Loans and LC Outstandings then outstanding as the principal amount of its Loans and LC Outstandings prior to such exercise of banker’s lien, setoff or counterclaim or other event was to the principal amount of all Loans
and LC Outstandings outstanding prior to such exercise of banker’s lien, setoff or counterclaim or other event; provided, however, that, if any such purchase or purchases or adjustments shall be made pursuant to this Section and the
payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. The Borrower expressly
consents to the foregoing arrangements and agrees that any Lender holding a participation in a Loan or any LC Outstandings deemed to have been so purchased may exercise any and all rights of banker’s lien, setoff or counterclaim with respect to
any and all moneys owing by the Borrower to such Lender by reason thereof as fully as if such Lender had made an Extension of Credit in the amount of such participation. 
 SECTION 2.14. Payments. 
 (a) The Borrower shall make each payment (including principal of or
interest on any Outstanding Credit or any Fees or other amounts) hereunder from an account in the United States not later than 12:00 noon, New York City time, on the date when due in dollars to the Agent at its offices at Two Penns Way, Suite 200,
New Castle, Delaware 19720, Attention: Bank Loan Syndications, in immediately available funds. Each such payment shall be made without off–set, deduction or counterclaim; provided, that the foregoing shall not constitute a relinquishment
or waiver of the Borrower’s rights to any independent claim that the Borrower may have against the Agent, any Fronting Bank or any Lender. 
  

 24 








 (b) Whenever any payment (including principal of or interest on any Outstanding Credit or any Fees or
other amounts) hereunder shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of
interest or Fees, if applicable. 
 SECTION 2.15. Taxes. 
 (a) Any and all payments of principal and interest on any of the Outstanding Credits or of any Fees or indemnity or expense reimbursements by the Borrower
hereunder (“Borrower Payments”) shall be made, in accordance with Section 2.14, free and clear of and without deduction for any and all current or future United States Federal, state and local taxes, levies, imposts,
deductions, charges or withholdings, and all liabilities with respect to the Borrower Payments, but only to the extent reasonably attributable to the Borrower Payments, excluding (i) income taxes imposed on the net income of the Agent, any Fronting
Bank or any Lender (or any transferee or assignee thereof, including a participation holder (any such entity a “Transferee”)) and (ii) franchise taxes imposed on the net income of the Agent, any Fronting Bank or any Lender
(or Transferee), in each case by the jurisdiction under the laws of which the Agent, such Fronting Bank or such Lender (or Transferee) is organized or doing business through offices or branches located therein, or any political subdivision thereof
(all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and liabilities, collectively or individually, “Taxes”). If the Borrower shall be required to deduct any Taxes from or in respect of any sum
payable hereunder to any Lender (or any Transferee) or the Agent, or any Fronting Bank (i) the sum payable shall be increased by the amount (an “additional amount”) necessary so that after making all required deductions
(including deductions applicable to additional amounts payable under this Section) such Lender (or Transferee) or the Agent or such Fronting 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 to the relevant United States Governmental Authority in accordance with applicable law any current or future
stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or the Letter
Agreements (“Other Taxes”). 
 (c) The Borrower shall indemnify each Lender (or Transferee thereof), the Agent and
each Fronting Bank for the full amount of Taxes and Other Taxes with respect to Borrower Payments paid by such person, and any liability (including penalties, interest and expenses (including reasonable attorney’s fees and expenses)) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted by the relevant United States Governmental Authority. A certificate setting forth and containing an explanation in reasonable detail of
the manner in which such amount shall have been determined and the amount of such payment or liability prepared by a Lender, a Fronting Bank or the Agent on their behalf, absent manifest error, shall be final, conclusive and binding for all
purposes. Such indemnification shall be made within 30 days after the date the Lender (or Transferee) or the Agent or the Fronting Bank, as the case may be, makes written demand therefor. 
  

 25 








 (d) If a Lender (or Transferee) or the Agent or a Fronting Bank shall become aware that it is entitled to
claim a refund from a United States Governmental Authority in respect of Taxes or Other Taxes as to which it has been indemnified by the Borrower, or with respect to which the Borrower has paid additional amounts, pursuant to this Section, it shall
promptly notify the Borrower of the availability of such refund claim and shall, within 30 days after receipt of a request by the Borrower, make a claim to such United States Governmental Authority for such refund at the Borrower’s expense. If
a Lender (or Transferee) or the Agent or a Fronting Bank receives a refund (including pursuant to a claim for refund made pursuant to the preceding sentence) in respect of any Taxes or Other Taxes as to which it has been indemnified by the Borrower
or with respect to which the Borrower had paid additional amounts pursuant to this Section, it shall within 30 days from the date of such receipt, pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional
amounts paid, by the Borrower under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Lender (or Transferee) or the Agent or such Fronting Bank and without interest (other
than interest paid by the relevant United States Governmental Authority with respect to such refund); provided, however, that the Borrower, upon the request of such Lender (or Transferee) or the Agent or such Fronting Bank, agrees to repay
the amount paid over to the Borrower (plus penalties, interest or other charges) to such Lender (or Transferee) or the Agent or such Fronting Bank in the event such Lender (or Transferee) or the Agent or such Fronting Bank is required to repay such
refund to such United States Governmental Authority. 
 (e) As soon as practicable, but in any event within 30 days, after the date of any
payment of Taxes or Other Taxes by the Borrower to the relevant United States Governmental Authority, the Borrower will deliver to the Agent, at its address referred to in Section 8.01, the original or a certified copy of a receipt issued by such
United States Governmental Authority evidencing payment thereof. 
 (f) Without prejudice to the survival of any other agreement contained
herein, the agreements and obligations contained in this Section shall survive the payment in full of the principal of and interest on all Outstanding Credits hereunder. 
 (g) Each of the Agent, each Fronting Bank and each Lender (or Transferee) that is organized under the laws of a jurisdiction other than the United States, any State thereof or the District of Columbia (a
“Non-U.S. Lender” or “Non U.S. Agent”, as applicable) shall deliver to the Borrower and the Agent two copies of either United States Internal Revenue Service Form W-8BEN or Form W-8ECI, properly
completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or reduced rate of, United States Federal withholding tax on payments by the Borrower under this Agreement. Such forms shall be delivered by each Non-U.S. Lender
on or before the date it becomes a party to this Agreement (or, in the case of a Transferee that is a participation holder, on or before the date such participation holder becomes a Transferee hereunder) and on or before the date, if any, such
Non-U.S. Lender changes its applicable lending office by designating a different lending office (a “New Lending Office”). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity
of any form previously delivered by such Non-U.S. Lender. Notwithstanding any other provision of this subsection (g), a Non-U.S. Lender shall not be required to deliver any form pursuant to this subsection (g) that such Non-U.S. Lender is not
legally able to deliver. 
  

 26 








 (h) The Borrower shall not be required to indemnify any Non-U.S. Lender or Non-U.S. Agent (including any
Transferee), or to pay any additional amounts to any Non-U.S. Lender or Non-U.S. Agent (including any Transferee), in respect of United States Federal, state or local withholding tax pursuant to subsection (a) or (c) above to the extent that (i) the
obligation to withhold amounts with respect to United States Federal, state or local withholding tax existed on the date such Non-U.S. Lender became a party to this Agreement (or, in the case of a Transferee that is a participation holder, on the
date such participation holder became a Transferee hereunder) or, with respect to payments to a New Lending Office, the date such Non-U.S. Lender designated such New Lending Office with respect to an Extension of Credit; provided,
however, that this clause (i) shall not apply to any Transferee or New Lending Office that becomes a Transferee or New Lending Office as a result of an assignment, participation, transfer or designation made at the request of the Borrower;
and provided further, however, that this clause (i) shall not apply to the extent the indemnity payment or additional amounts any Transferee, or any Fronting Bank or any Lender (or Transferee) through a New Lending Office, would be entitled to
receive (without regard to this clause (i)) do not exceed the indemnity payment or additional amounts that the person making the assignment, participation or transfer to such Transferee, or such Fronting Bank or Lender (or Transferee) making the
designation of such New Lending Office, would have been entitled to receive in the absence of such assignment, participation, transfer or designation or (ii) the obligation to pay such additional amounts or such indemnity payments would not have
arisen but for a failure by such Non-U.S. Lender (including any Transferee) to comply with the provisions of subsection (g) above and (i) below. 
 (i) Any Fronting Bank or any Lender (or Transferee) claiming any indemnity payment or additional amounts payable pursuant to this Section shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any
certificate or document reasonably requested in writing by the Borrower or to change the jurisdiction of its applicable lending office if the making of such a filing or change would avoid the need for or reduce the amount of any such indemnity
payment or additional amounts that may thereafter accrue and would not, in the good faith determination of such Fronting Bank or such Lender (or Transferee) (as the case may be), be otherwise disadvantageous to such Fronting Bank or such Lender (or
Transferee) (as the case may be). 
 (j) Nothing contained in this Section shall require any Lender (or Transferee) or the Agent or any
Fronting Bank to make available to the Borrower any of its tax returns (or any other information) that it deems to be confidential or proprietary. 
 SECTION 2.16. Assignment of Commitments Under Certain Circumstances. 
 In the event that any Lender shall have
delivered a notice or certificate pursuant to Section 2.10(c) or 2.11(a), or the Borrower shall be required to make additional payments to any Lender under Section 2.15, the Borrower shall have the right, at their own expense, upon notice to such
Lender and the Agent, to require such Lender to transfer and assign without recourse (in accordance with and subject to the restrictions contained in Section 8.04) all such Lender’s interests, rights and obligations contained hereunder to
another financial institution approved by the Agent and the Borrower (which approval shall not be unreasonably withheld) which shall assume such obligations; provided that (i) no such assignment shall conflict with any law, rule or

  

 27 








 regulation or order of any Governmental Authority and (ii) the assignee shall pay to the affected Lender in immediately
available funds on the date of such assignment the principal of and interest accrued to the date of payment on the Loans made by it hereunder and all other amounts accrued for its account or owed to it hereunder and the Borrower shall pay the
processing and recordation fee due pursuant to Section 8.04. 
 SECTION 2.17. Letters of Credit. 
 (a) Subject to the terms and conditions hereof, each Letter of Credit shall be issued (or the stated maturity thereof extended or terms thereof modified
or amended) on not less than three Business Days’ prior notice thereof by the delivery by the Borrower of a Request for Issuance to the Agent (which shall promptly distribute copies thereof to the Lenders) and the Fronting Bank designated by
the Borrower. Each Request for Issuance shall identify the relevant Fronting Bank and shall specify (i) the date (which shall be a Business Day) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or
amendment) and the stated expiry date thereof (which shall be no later than the fifth Business Day preceding the Commitment Termination Date), (ii) the proposed stated amount (denominated in dollars) of such Letter of Credit (which shall not be less
than $1,000,000, unless otherwise agreed to by the applicable Fronting Bank), (iii) the name and address of the beneficiary of such Letter of Credit and (iv) a statement of drawing conditions applicable to such Letter of Credit, whether such Letter
of Credit is a documentary letter of credit, a financial standby letter of credit or a performance standby letter of credit, and if such Request for Issuance relates to an amendment or modification of a Letter of Credit, it shall be accompanied by
the consent of the beneficiary of the Letter of Credit thereto; provided, however, that if the terms of any Request for Issuance shall conflict with the terms of this Agreement, the terms of this Agreement shall govern. Each Request for Issuance
shall be irrevocable unless modified or rescinded by the Borrower not less than two days prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 12:00 noon (New York City time) on the proposed date of issuance (or
effectiveness) specified in such Request for Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements set forth herein, the applicable Fronting Bank shall issue (or extend, amend or modify) such Letter of
Credit and provide notice and a copy thereof to the Agent, which shall promptly furnish copies thereof to the Lenders. Each Lender shall, upon the issuance of any Letter of Credit, acquire a participation interest in such Letter of Credit,
automatically and without any action on its part or the part of the applicable Fronting Bank, whereby such Lender shall become obligated to perform such obligations in respect of such Letter of Credit as are expressly set forth herein. No Fronting
Bank shall at any time be obligated to issue any Letter of Credit if such issuance would conflict with any applicable requirement of law. 
 (b) No Letter of Credit shall be requested or issued hereunder if, after the issuance thereof, the Outstanding Credits would exceed the Commitments. 
 (c) The Borrower hereby agrees to pay to the Agent for the account of each Fronting Bank and, if they shall have funded participations in the reimbursement obligations of the Borrower pursuant to subsection (d) below,
the Lenders, on demand made by such Fronting Bank to the Borrower, on and after each date on which such Fronting Bank shall pay any amount under any Letter of Credit issued by such Fronting Bank for the account of the Borrower, a sum 
  

 28 








 equal to the amount so paid plus interest on such amount from the date so paid by such Fronting Bank until repayment to
such Fronting Bank in full at a fluctuating interest rate per annum equal to the Alternate Base Rate plus the Applicable Margin for ABR Loans plus, if any amount paid by such Fronting Bank under a Letter of Credit is not reimbursed by the
Borrower within three Business Days, 2%. 
 (d) If any Fronting Bank shall not have been reimbursed in full by the Borrower for any payment
made by such Fronting Bank under a Letter of Credit issued by such Fronting Bank for the account of the Borrower on the date of such payment, such Fronting Bank shall give the Agent prompt notice thereof (an “LC Payment
Notice”) no later than 10:00 a.m. (New York City time) on the Business Day immediately succeeding the date of such payment by such Fronting Bank. The Agent shall forward to each Lender a copy of such LC Payment Notice no later than
12:00 noon on the date on which such LC Payment Notice is received from such Fronting Bank. Notwithstanding any provision of this Agreement to the contrary, each Lender severally agrees to fund its participation in the reimbursement obligation of
the Borrower to each Fronting Bank by paying to the Agent for the account of such Fronting Bank an amount equal to such Lender’s Percentage of such unreimbursed amount paid by such Fronting Bank, plus interest on such amount at a rate per
annum equal to the Federal Funds Effective Rate from the date of the payment by such Fronting Bank to the date of payment to such Fronting Bank by such Lender. Each such payment by a Lender shall be made not later than 3:00 p.m. (New York City
time) on the later to occur of (i) the Business Day immediately following the date of such payment by such Fronting Bank and (ii) the Business Day on which the Lender shall have received an LC Payment Notice from such Fronting Bank. Each
Lender’s obligation to make each such payment to the Agent for the account of each Fronting Bank shall be several and shall not be affected by the occurrence or continuance of a Default or Event of Default or the failure of any other Lender to
make any payment under this subsection (d). Each Lender further agrees that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 
 (e) The failure of any Lender to make any payment to the Agent for the account of any Fronting Bank in accordance with subsection (d) above shall not
relieve any other Lender of its own obligation to make any similar payment to the Agent, but no Lender shall be responsible for the failure of any other Lender to make any such payment. If any Lender (a “non–performing Lender”) shall
fail to make any payment to the Agent for the account of any Fronting Bank in accordance with subsection (d) above within five Business Days after the LC Payment Notice relating thereto, then, for so long as such failure shall continue, (i) such
Fronting Bank shall be deemed to be a Lender hereunder owed a Loan, and for purposes of voting rights hereunder, having a Commitment increased by an amount equal to the outstanding principal amount due and payable by such non–performing Lender
to the Agent for the account of such Fronting Bank pursuant to subsection (d) above and (ii) for purposes of voting rights hereunder, the Commitment of such non-performing Lender shall be reduced in an amount equal to such outstanding principal
amount due and payable by such non-performing Lender. Any non–performing Lender and the Borrower for the account of which the relevant Letter of Credit was issued (without waiving any claim against such Lender for such Lender’s failure to
fund a participation in the reimbursement obligations of the Borrower under subsection (d) above) severally agree to pay to the Agent for the account of the applicable Fronting Bank forthwith on demand such amount, together with interest thereon for
each day from the date such Lender would have funded its participation had it complied with the requirements of subsection (d) 
  

 29 








 above until the date such amount is paid to the Agent at (A) in the case of the Borrower, the interest rate applicable at
the time to ABR Loans (or the interest rate that would be applicable if ABR Loans were outstanding) and (B) in the case of such Lender, the Federal Funds Effective Rate. 
 (f) The payment obligations of each Lender under subsection (d) above and of the Borrower under this Agreement in respect of any payment under any Letter of Credit shall be unconditional and irrevocable, and shall be
paid strictly in accordance with the terms of this Agreement under all circumstances, including, without limitation, the following circumstances: 
 (i) any lack of validity or enforceability of this Agreement or any other agreement or instrument relating hereto or to such Letter of Credit; 
 (ii) any amendment or waiver of, or any consent to departure from, the terms of this Agreement or such Letter of Credit; 
 (iii) the existence of any claim, set–off, defense or other right that any Lender or the Borrower for the account of which such
Letter of Credit was issued may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any persons for whom any such beneficiary or any such transferee may be acting), any Fronting Bank, or any other person,
whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit, or any unrelated transaction; 
 (iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any
respect; 
 (v) payment in good faith by any Fronting Bank under the Letter of Credit issued by such Fronting Bank against
presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or 
 (vi) any other
circumstance or happening whatsoever, whether or not similar to any of the foregoing. 
 (g) The Borrower assumes all risks of the acts and
omissions of any beneficiary or transferee of any Letter of Credit issued for the account of the Borrower. Neither any Fronting Bank, any Lender, nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or
responsible for (i) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith; (ii) the validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (iii) payment by any Fronting Bank against presentation of documents that do not comply with the terms of such Letter of Credit,
including failure of any documents to bear any reference or adequate reference to such Letter of Credit; or (iv) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit, except that the Borrower for the
account of which such Letter of Credit was issued and each Lender shall have the right to bring suit against the applicable Fronting Bank, and such Fronting Bank shall be liable to the Borrower and any 
  

 30 








 Lender, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower or such Lender which
the Borrower or such Lender proves were caused by such Fronting Bank’s willful misconduct or gross negligence, including, in the case of the Borrower, such Fronting Bank’s willful failure to make timely payment under such Letter of Credit
following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) which strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, each Fronting
Bank may accept sight drafts and accompanying certificates presented under any Letter of Credit issued by such Fronting Bank that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or
information to the contrary, and payment against such documents shall not constitute willful misconduct or gross negligence by such Fronting Bank. Without limiting the foregoing, no Lender shall be obligated to indemnify the Borrower for damages
caused by any Fronting Bank’s willful misconduct or gross negligence. 
 (h) If there shall be more than one Fronting Bank that has
issued a Letter of Credit at any time hereunder, each such Fronting Bank shall, with respect to the Letters of Credit issued by it and the reimbursement obligations owing to it, be regarded hereunder as the “Fronting Bank” and shall have
all of the rights, interests, protections and obligations of the “Fronting Bank” hereunder with respect to such Letters of Credit and reimbursement obligations and all matters relating thereto. Whenever any action may be, or is required to
be, taken by the Fronting Bank hereunder, each Fronting Bank may, or shall, take such action only in respect of the Letters of Credit issued by it and the reimbursement obligations owing to it. Whenever the consent of the Fronting Bank is required
hereunder with respect to any proposed action, the consent of each Fronting Bank of a Letter of Credit that is then outstanding, or in respect of which reimbursement obligations remain outstanding, shall be required for such proposed action to be
taken. Any notice to be provided to the Fronting Bank shall be provided to each Fronting Bank of a Letter of Credit that is then outstanding, or in respect of which reimbursement obligations remain outstanding, and each such Fronting Bank shall have
the right to request any information, and take any other action, as the Fronting Bank is permitted to do hereunder. The protections accorded the Fronting Bank hereunder shall inure to the benefit of each Fronting Bank, regardless of whether any
Letter of Credit issued by any such Fronting Bank or any reimbursement obligations in respect thereof are outstanding at the time the benefits of such protections are asserted. 
 (i) No Fronting Bank shall at any time be obligated to issue any Letter of Credit if such issuance would result in the aggregate of the Stated Amounts of
all Letters of Credit issued by such Fronting Bank exceeding such Fronting Bank’s LC Fronting Bank Commitment.

pursuant to or in connection with this Agreement contains or will contain any material misstatement of fact or omits or will omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they
were or will be made, not misleading; provided that, with respect to projections and forward looking statements, the Borrower represents only that such information was prepared in good faith based upon assumptions and estimates believed to be
reasonable at

 so comply could not reasonably be expected to result in a Material Adverse Change. Except as set forth in or contemplated
by the Borrower Information, neither the Borrower nor any of its Subsidiaries has received notice of any material failure so to comply, except where such failure could not reasonably be expected to result in a Material Adverse Change. Except as set

 Notwithstanding anything to the contrary contained herein, no notice given or declaration made by the Agent pursuant to this Article VI shall affect (i)
the obligation of any Fronting Bank to make any payment under any Letter of Credit issued by such Fronting Bank in accordance with the terms of such Letter of Credit or (ii) the obligations of each Lender in respect of each such Letter of Credit;

with the Agent an amount in the cash collateral account (the “Cash Collateral Account”) described below equal to the aggregate maximum amount available to be drawn under all Letters of Credit issued for the account of the
Borrower and outstanding at such time. Such Cash Collateral Account shall at all times be free and clear of all rights or claims of third parties. The Cash Collateral Account shall be maintained with the Agent or at a depositary bank acting on
behalf of the Agent in the name of, and under the sole dominion and control of, the Agent, and amounts deposited in the Cash Collateral Account shall bear interest at a rate equal to the rate generally offered by CS or such depositary bank, as the
case may be, for deposits equal to the amount deposited by the Borrower in the Cash Collateral Account, for a term to be determined by the Agent in its sole discretion. The Borrower hereby grants to the Agent for the benefit of the Fronting Banks
and the Lenders a Lien on, and hereby assigns to the Agent for the benefit of the Fronting Banks and the Lenders all of its right, title and interest in, the Cash Collateral Account and all funds from time to time on deposit therein to secure its
reimbursement obligations in respect of Letters of Credit issued for its account. If any drawings then outstanding or thereafter made are not reimbursed in full immediately upon demand or, in the case of subsequent drawings, upon being made, then,
in any such event, the Agent may apply the amounts then on deposit in the Cash Collateral Account, in such priority as the Agent shall elect, toward the payment in full of any or all of the Borrower’s obligations hereunder as and when such
obligations shall become due and payable, regardless of whether the amounts to be so applied were deposited by the Borrower for the account of which the Letter(s) of Credit then being drawn were issued. Upon payment in full, after the termination of
the Letters of Credit, of all such obligations, the Agent will repay and reassign to the Borrower any cash then on deposit in the Cash Collateral Account and the Lien of the Agent on the Cash Collateral Account and the funds therein shall
automatically terminate.

 (a) In order to expedite the transactions contemplated by this Agreement, CS is hereby
appointed to act as Agent on behalf of the Lenders and the Fronting Banks. Each Lender and each Fronting Bank hereby irrevocably authorizes the Agent to take such actions on behalf of such Lender and such Fronting Bank and to exercise such powers as
are specifically delegated to the Agent by the terms and provisions hereof, together with such actions and powers as are reasonably incidental thereto. The Agent is hereby expressly authorized by the Lenders and the Fronting Banks, without hereby
limiting any implied authority, (i) to receive on behalf of the Lenders and the Fronting Banks all payments of principal of and interest on the Outstanding Credits and all other amounts due to the Lenders and the Fronting Banks hereunder, and
promptly to distribute to each Lender and each Fronting Bank, its proper share of each payment so received; (ii) to give notice on behalf of each Lender and each Fronting Bank to the Borrower of any Event of Default of which the Agent has actual
knowledge acquired in connection with its agency hereunder; and (iii) to distribute to each Lender and each Fronting Bank copies of all notices, financial statements and other materials delivered by the Borrower pursuant to this Agreement as
received by the Agent. 
 (b) Neither the Agent nor any of its directors, officers, employees or agents shall be liable as such for any
action taken or omitted by any of them except for its or his or her own gross negligence or willful misconduct, or be responsible for any statement, warranty or representation herein or the contents of any document delivered in connection herewith,
or be required to ascertain or to make any inquiry concerning the performance or observance by the Borrower of any of the terms, conditions, covenants or agreements contained in this Agreement. The Agent shall not be responsible to the Lenders or
the Fronting Banks for the due execution, genuineness, validity, enforceability or effectiveness of this Agreement or other instruments or agreements. The Agent may deem and treat the Lender or the Fronting Bank that makes any Extension of Credit as
the holder of the indebtedness resulting therefrom for all purposes hereof until it shall have received notice from such Lender or such Fronting Bank, given as provided herein, of the transfer thereof. The Agent shall in all cases be fully protected
in acting, or refraining from acting, in accordance with written instructions signed by the Required Lenders and, except as otherwise specifically provided herein, such instructions and any action or inaction pursuant thereto shall be binding on all
the Lenders and the Fronting Banks. The Agent shall, in the absence of knowledge to the contrary, be entitled to rely on any instrument or document believed by it in good faith to be genuine and correct and to have been signed or sent by the proper
person or persons. Neither the Agent nor any of its directors, officers, employees or agents shall have any responsibility to the Borrower on account of the failure of or delay in performance or breach by any Lender or any Fronting Bank of any of
its obligations hereunder or to any Lender or any Fronting Bank on account of the failure of or delay in performance or breach by any other Lender, any Fronting Bank or the Borrower of any of their respective obligations hereunder or in connection
herewith. The Agent may execute any and all duties hereunder by or through agents or employees and shall be entitled to rely upon the advice of legal counsel selected by it with respect to all matters arising hereunder and shall not be liable for
any action taken or suffered in good faith by it in accordance with the advice of such counsel. 
  

 47 








 (c) The Lenders and the Fronting Banks hereby acknowledge that the Agent shall not be under any duty to
take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement unless it shall be requested in writing to do so by the Required Lenders. 
 (d) Subject to the appointment and acceptance of a successor Agent as provided below, the Agent may resign at any time by notifying the Lenders, the
Fronting Banks and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Agent acceptable to the Borrower. If no successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the Agent gives notice of its resignation, then the Agent may, on behalf of the Lenders and the Fronting Banks, appoint a successor Agent, having a combined capital and surplus of at least $500,000,000
or an Affiliate of any such bank. Upon the acceptance of any appointment as Agent hereunder by a successor bank, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent and the Agent
shall be discharged from its duties and obligations hereunder. After the Agent’s resignation hereunder, the provisions of this Article and Section 8.05 shall continue in effect for its benefit in respect of any actions taken or omitted to be
taken by it while it was acting as the Agent. 
 (e) With respect to the Extensions of Credit made by it hereunder, the Agent, in its
individual capacity and not as Agent, shall have the same rights and powers as any other Lender and may exercise the same as though it were not the Agent, and the 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 other Affiliate thereof as if it were not Agent. 
 (f) Each Lender agrees (i)
to reimburse the Agent, on demand, in the amount of its pro rata share (based on its Commitment hereunder or, if the Commitments shall have been terminated, the amount of its percentage of Outstanding Credits) of any expenses incurred for the
benefit of the Lenders or the Fronting Banks, in its role as Agent, including counsel fees and compensation of agents and employees paid for services rendered on behalf of the Lenders or the Fronting Banks, which shall not have been reimbursed by
the Borrower and (ii) to indemnify and hold harmless the Agent and any of its directors, officers, employees or agents, on demand, in the amount of such pro rata share, from and against any and all liabilities, taxes, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by or asserted against it in any way relating to or arising out of this Agreement or any action taken
or omitted by it under this Agreement to the extent the same shall not have been reimbursed by the Borrower; provided that neither any Lender nor any Fronting Bank shall be liable to the Agent for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Agent or any of its directors, officers, employees or agents. Each Lender and each Fronting Bank
agrees that any allocation made in good faith by the Agent of expenses or other amounts referred to in this subsection (f) shall be conclusive and binding for all purposes. 
 (g) Each Lender and each Fronting Bank acknowledges that it has, independently and without reliance upon the Agent or any other Lender or Fronting Bank,
and based on such documents and information as it has deemed appropriate, made its own credit analysis and 
  

 48 








 decision to enter into this Agreement. Each Lender and each Fronting Bank also acknowledges that it will, independently
and without reliance upon the Agent or any other Lender or Fronting Bank, and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based
upon this Agreement or any related agreement or any document furnished hereunder or thereunder. 
 (h) Neither Lehman Brothers Inc. nor
Credit Suisse Securities (USA) LLC, by virtue of its designation as a “Joint Lead Arranger and Bookrunners” on the cover page of this Agreement, shall have any duties, liabilities, obligations or responsibilities under this Agreement other
than, if applicable, as the Agent, or as a Lender or as a Fronting Bank hereunder.

 (i) Any Lender may at any time pledge all or any portion of its rights under this Agreement to a Federal Reserve Bank; provided that no such pledge shall release any Lender from its obligations hereunder or substitute
any such Bank for such Lender as a party hereto. In order to facilitate such an assignment to a Federal Reserve Bank, the Borrower shall, at the request of the assigning Lender, duly execute and deliver to the assigning Lender a promissory note or
notes evidencing the Loans made to the Borrower by the assigning Lender hereunder. 
 (j) Subject to the appointment and acceptance of a
successor Fronting Bank as provided below, any Fronting Bank may resign at any time by notifying the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Fronting Bank acceptable to
the Borrower. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Fronting Bank gives notice of its resignation, then the retiring Fronting Bank may appoint
a successor Fronting Bank, having a combined capital and surplus of at least $500,000,000 or an Affiliate of any such bank. Upon the acceptance of any appointment as Fronting Bank hereunder by a successor bank, such successor shall succeed to and
become vested with all the rights, powers, privileges and duties of the retiring Fronting Bank and the retiring Fronting Bank shall be discharged from its duties and obligations hereunder. After a Fronting Bank’s resignation hereunder, the
provisions of Sections 2.10, 2.15 and 8.05 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Fronting Bank. 
  

 52 








 SECTION 8.05. Expenses; Indemnity. 
 (a) The Borrower agrees to pay all reasonable out-of-pocket expenses (including reasonable fees, charges and disbursements of one counsel, unless in the
good faith opinion of the Agent or such counsel, it would be inappropriate under applicable standards of legal professional conduct, due to an actual or potential conflict of interest, to have only one counsel) incurred by the Agent in connection
with the preparation, execution and delivery of this Agreement or in connection with any amendments, modifications or waivers of the provisions hereof (but only if such amendments, modifications or waivers are requested by the Borrower) (whether or
not the transactions hereby contemplated are consummated), or incurred by the Agent or any Lender in connection with the enforcement of their rights in connection with this Agreement (including in respect of workouts and restructurings) or in
connection with the Extensions of Credit made hereunder, including the reasonable fees and disbursements of one counsel (unless in the good faith opinion of the Agent or such counsel, it would be inappropriate under applicable standards of legal
professional conduct, due to an actual or potential conflict of interest, to have only one counsel) for the Agent or, in the case of enforcement following an Event of Default, the Lenders. In addition to the foregoing, the Borrower shall pay or
reimburse the Fronting Bank that issued such Letter of Credit for such reasonable, normal and customary costs and expenses as are incurred or charged by such Fronting Bank in issuing, negotiating, effecting payment under, amending or otherwise
administering such Letter of Credit. 
 (b) The Borrower agrees to indemnify each Lender and each Fronting Bank against any loss, calculated
in accordance with the next sentence, or reasonable expense that such Lender may sustain or incur as a consequence of (i) any failure by the Borrower to borrow or to refinance, convert or continue any Loan hereunder (including as a result of the
Borrower’s failure to fulfill any of the applicable conditions set forth in Article IV) after irrevocable notice of such borrowing, refinancing, conversion or continuation has been given pursuant to Section 2.03, (ii) any payment, prepayment or
conversion of a Eurodollar Loan of the Borrower, or assignment of a Eurodollar Loan of the Borrower required by any other provision of this Agreement or otherwise made or deemed made, on a date other than the last day of the Interest Period, if any,
applicable thereto, (iii) any default in payment or prepayment of the principal amount of any Outstanding Credit or any part thereof or interest accrued thereon, as and when due and payable (at the due date thereof, whether by scheduled maturity,
acceleration, irrevocable notice of prepayment or otherwise) or (iv) the occurrence of any Event of Default relating to the Borrower, including, in each such case, any loss or reasonable expense sustained or incurred or to be sustained or incurred
by such Lender in liquidating or employing deposits from third parties, or with respect to commitments made or obligations undertaken with third parties, to effect or maintain any Loan hereunder or any part thereof as a Eurodollar Loan. Such loss
shall include an amount equal to the excess, if any, as reasonably determined by such Lender, of (x) its cost of obtaining the funds for the Loan being paid, prepaid, refinanced, converted or not borrowed (assumed to be the LIBO Rate for the period
from the date of such payment, prepayment, refinancing or failure to borrow or refinance to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow or refinance, the Interest Period for such Loan that would have
commenced on the date of such failure) over (y) the amount of interest (as reasonably determined by such Lender) that would be realized by such Lender in reemploying the funds so paid, prepaid or not borrowed or refinanced for such period or
Interest Period, as the case may be. 
  

 53 








 (c) The Borrower agrees to indemnify the Agent, the Fronting Banks, each Lender, each of their Affiliates
and the directors, officers, employees and agents of the foregoing (each such person being called an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all costs, losses, claims, damages, liabilities
and related expenses, including reasonable fees and expenses of one counsel for all Indemnitees (unless in the good faith opinion of the Agent or such counsel, it would be inappropriate under applicable standards of legal professional conduct, due
to an actual or potential conflict of interest, to have only one counsel), incurred by or asserted against any Indemnitee arising out of the Borrower’s acts or omissions in connection with (i) the preparation, execution, delivery, enforcement,
performance and administration of this Agreement, (ii) the use of the proceeds of the Extensions of Credit or (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party
thereto, including any of the foregoing arising from the negligence, whether sole or concurrent, on the part of any Indemnitee. Notwithstanding the foregoing, such indemnity shall not, as to any Indemnitee, be available to the extent that such
losses, claims, damages, liabilities or related expenses (i) are determined by a final judgment of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee or (ii) result from any
litigation brought by such Indemnitee against the Borrower or by the Borrower against such Indemnitee, in which a final, nonappealable judgment has been rendered against such Indemnitee; provided, further, that the Borrower agrees that it
will not, nor will it permit any Subsidiary to, without the prior written consent of each Indemnitee, settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action, suit or proceeding in respect of which
indemnification could be sought under the indemnification provisions of this subsection (c) (whether or not any Indemnitee is an actual or potential party to such claim, action, suit or proceeding), unless such settlement, compromise or consent does
not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any Indemnitee and does not involve any payment of money or other value by any Indemnitee or any injunctive relief or factual findings or
stipulations binding on any Indemnitee. 
 (d) The provisions of this Section shall remain operative and in full force and effect regardless
of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Outstanding Credits, the invalidity or unenforceability of any term or provision of this Agreement or any
investigation made by or on behalf of the Agent, any Lender or any Fronting Bank. All amounts due under this Section shall be payable on written demand therefor. 
 (e) A certificate of any Lender, any Fronting Bank or the Agent setting forth any amount or amounts that such Lender, such Fronting Bank or such Agent is entitled to receive pursuant to subsection (b) above and
containing an explanation in reasonable detail of the manner in which such amount or amounts shall have been determined shall be delivered to the Borrower and shall be conclusive absent manifest error. 
 SECTION 8.06. Right of Setoff. 
 If an Event of Default shall have occurred and be continuing, each Lender and each Fronting Bank 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 
  

 54 








 or such Fronting Bank to or for the credit or the account of the Borrower against any of and all the obligations of the
Borrower now or hereafter existing under this Agreement held by such Lender or such Fronting Bank (as the case may be), irrespective of whether or not such Lender, or such Fronting Bank (as the case may be) shall have made any demand under this
Agreement and although such obligations may be unmatured. The rights of each Lender and each Fronting Bank under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender or such Fronting Bank may
have. 
 SECTION 8.07. Applicable Law. 
 THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. 
 SECTION 8.08. Waivers; Amendment. 
 (a) No failure or delay of the Agent, any Fronting Bank or any Lender 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 remedies of the Agent, the Fronting Banks and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provision of this Agreement or consent to any departure therefrom shall in any event be effective unless the same shall be permitted by subsection (b) below, and then such waiver or consent shall be effective only in the specific
instance and for the purpose for which given. No notice or demand on the Borrower or any Subsidiary in any case shall entitle such party to any other or further notice or demand in similar or other circumstances. 
 (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered
into by the Borrower and the Required Lenders; provided, however, that no such agreement shall (i) decrease the principal amount of, or extend the maturity of or any scheduled principal payment date, or date for the payment of any interest
on, any Loan or reimbursement obligation in respect of a Letter of Credit or date for the payment of any Commitment Fee or LC Fee, or waive or excuse any such payment or any part thereof, or decrease the rate of interest on any Loan or any
reimbursement obligation in respect of a Letter of Credit, without the prior written consent of each Lender affected thereby, (ii) increase the Commitment of any Lender, decrease the Commitment Fee or decrease the LC Fee payable to any Lender
without the prior written consent of such Lender, or (iii) amend or modify the provisions of Section 2.12, Section 2.13 or Section 8.04(h), the provisions of this Section or the definition of the “Required Lenders”, without the prior
written consent of each Lender; provided further, however, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Agent or any Fronting Bank hereunder without the prior written consent of the Agent or the
applicable Fronting Bank, as the case may be. Each Lender and each Fronting Bank shall be bound by any waiver, amendment or modification authorized by this Section, and any consent by any Lender, the Agent or any Fronting Bank pursuant to this
Section shall bind any assignee of its rights and interests hereunder. 
  

 55 








 SECTION 8.09. Entire Agreement. 
 This Agreement (including the schedules and exhibits hereto) and the Letter Agreements represent the entire contract among the parties relative to the
subject matter hereof and thereof. Any previous agreement, whether written or oral, among the parties with respect to the subject matter hereof, is superseded by this Agreement and the Letter Agreements. There are no unwritten oral agreements
between the parties. Nothing in this Agreement, expressed or implied, is intended to confer upon any party other than the parties hereto any rights, remedies, obligations or liabilities under or by reason of this Agreement. 
 SECTION 8.10. Severability. 
 In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in
any way be affected or impaired thereby. The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the
invalid, illegal or unenforceable provisions. 
 SECTION 8.11. Counterparts. 
 This Agreement may be executed in two or more counterparts, each of which shall constitute an original but all of which when taken together shall
constitute but one contract, and shall become effective as provided in Section 8.03. 
 SECTION 8.12. Headings. 
 Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to
affect the construction of, or to be taken into consideration in interpreting, this Agreement. 
 SECTION 8.13. Interest Rate
Limitation. 
 (a) Notwithstanding anything herein to the contrary, if at any time the applicable interest rate, together with all
fees and charges which are treated as interest under applicable law (collectively the “Charges”), as provided for herein or in any other document executed in connection herewith, or otherwise contracted for, charged,
received, taken or reserved by any Lender or any Fronting Bank, shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by such Lender or such Fronting Bank
(as the case may be) in accordance with applicable law, the rate of interest payable on the Outstanding Credits of such Lender or such Fronting Bank (as the case may be), together with all Charges payable to such Lender or such Fronting Bank (as the
case may be), shall be limited to the Maximum Rate. 
 (b) If the amount of interest, together with all Charges, payable for the account of
any Lender or any Fronting Bank in respect of any interest computation period is reduced pursuant to subsection (a) above and the amount of interest, together with all Charges, payable for such Lender’s or such Fronting Bank’s (as the case
may be) account in respect of any subsequent 
  

 56 








 interest computation period, would be less than the Maximum Rate, then the amount of interest, together with all Charges,
payable for such Lender’s or such Fronting Bank’s (as the case may be) account in respect of such subsequent interest computation period shall, to the extent permitted by applicable law, be automatically increased to such Maximum Rate;
provided that at no time shall the aggregate amount by which interest paid for the account of any Lender or any Fronting Bank has been increased pursuant to this subsection (b) exceed the aggregate amount by which interest, together with all
Charges, paid for its account has theretofore been reduced pursuant to subsection (a) above. 
 SECTION 8.14. Jurisdiction; Venue.

 (a) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of
any New York State court or Federal court of the United States of America sitting in New York City, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement, or for recognition or enforcement
of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such
Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Subject to the
foregoing and to subsection (b) below, nothing in this Agreement shall affect any right that any party hereto may otherwise have to bring any action or proceeding relating to this Agreement against any other party hereto in the courts of any
jurisdiction. 
 (b) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so,
any objection which it may now or thereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any New York State court or Federal court of the United States of America sitting in New York
City. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 
 SECTION 8.15. Confidentiality. 
 The Agent, each Lender and each Fronting Bank shall use its best efforts to hold in confidence all information, memoranda, or extracts furnished to the Agent or to such Lender or such Fronting Bank (as the case may be) (directly or through
the Agent) by the Borrower hereunder or in connection with the negotiation hereof; provided that the Agent, such Lender and such Fronting Bank may disclose any such information, memoranda or extracts (i) to its Affiliates, accountants or
counsel, (ii) to any regulatory agency having authority to examine the Agent or such Lender or such Fronting Bank (as the case may be), (iii) as required by any legal or governmental process or otherwise by law including in connection with the
exercise of remedies following an Event of Default, (iv) except as provided in the last sentence of Section 5.03, to any person to which such Lender sells or proposes to sell an assignment or a participation in its Outstanding Credits hereunder, if
such other person agrees for the benefit of the Borrower to comply with the provisions of this Section and (v) to the extent that such 
  

 57 








 information, memoranda or extracts shall be publicly available or shall have become known to the Agent or such Lender or
such Fronting Bank (as the case may be) independently of any disclosure by the Borrower hereunder or in connection with the negotiation hereof. Notwithstanding the foregoing, any Lender may disclose the provisions of this Agreement, the amounts,
maturities and interest rates of its Outstanding Credits, and any Fees to which it is entitled, to any purchaser or potential purchaser of such Lender’s interest in any Outstanding Credits. Notwithstanding any other provision in this Agreement,
the Agent hereby confirms that the Borrower and the representatives of the Borrower shall not be limited from disclosing the U.S. tax treatment or the U.S. tax structure of the transactions contemplated by this Agreement. 
 SECTION 8.16. Electronic Communications. 
 (a) The Borrower hereby agrees that it will provide to the Agent all information, documents and other materials that it is obligated to furnish to the Agent pursuant to Section 5.03 (collectively, the
“Communications”) by transmitting the Communications in Microsoft Word, Adobe Portable Document Format (PDF) or other electronic/soft medium format that is reasonably acceptable to the Agent to
james.moran@credit-suisse.com or faxing the Communications to 212-743-1878, or to such other addressee as the Agent may notify the Borrower from time to time. In addition, the Borrower agrees to continue to provide the Communications to the
Agent in the manner otherwise specified in this Agreement, but only to the extent reasonably requested by the Agent. 
 (b) The Agent agrees
that the receipt of the Communications by the Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the Agent for purposes of this Agreement. Each Lender and each Fronting Bank agrees to notify the
Agent in writing (including by electronic communication) from time to time of such Lender’s or Fronting Bank’s e-mail address to which the foregoing notice may be sent by electronic transmission and that the foregoing notice may be sent to
such e-mail address. 
 (c) Nothing herein shall prejudice the right of the Agent or any Lender or Fronting Bank to give any notice or other
communication pursuant to this Agreement in any other manner specified in this Agreement.
