made a Term A Advance pursuant to the Existing Credit Agreement. Any Term A Advance which is repaid or prepaid may not be reborrowed. 
  
 (b) The Term B Advances. Each Term B Lender severally agrees, on the terms and conditions hereinafter set forth, to make a single
Term B advance (a “Term B Advance”) in U.S. dollars to the Borrower, on the Closing Date in an amount equal to the Term B Commitment of such Term B Lender. The Term B Borrowing shall consist of Term B Advances made
simultaneously by the Term B Lenders in accordance with their respective Pro Rata Shares of the Term B Facility. Amounts borrowed under this Section 2.01(b) and repaid or prepaid may not be reborrowed.

Credit Lender severally agrees, on the terms and conditions hereinafter set forth, to make advances (each a “Revolving Credit Advance”) in U.S. dollars to the Borrower from time to time until the Termination Date, in each
case in an amount not to exceed the Unused Revolving Credit Commitment of such Revolving Credit Lender at such time. Each Revolving Credit Borrowing shall be in an aggregate amount of $5,000,000 or an integral multiple of $1,000,000 in excess
thereof (other than a Borrowing the proceeds of which shall be used solely to repay or prepay in full outstanding Swing Line Advances or the outstanding Letter of Credit Advances) or, if less, the amount of the aggregate Unused Revolving Credit
Commitments at such time. Each Revolving Credit Borrowing shall consist of Revolving Credit Advances made simultaneously by the Revolving Credit Lenders in accordance with their respective Pro Rata Shares of the Revolving Credit Facility. Within the

Credit Lenders at such time. No Swing Line Advance shall be used for the purpose of funding the payment of principal of any other Swing Line Advance. Each Swing Line Borrowing shall be in an amount of $500,000 or an integral multiple of $250,000 in
excess thereof and shall bear interest at a rate to be agreed on by the Borrower and the Swing Line Bank. Within the limits of the first sentence of this Section 2.01(d), the Borrower may borrow under this Section 2.01(d), repay pursuant to Section
2.04(c), prepay pursuant to Section 2.06(a) and reborrow under this Section 2.01(d). 
  
 (e) Letters of Credit. 
  
 (i) The Borrower, the Existing Issuing Banks and each of the Revolving Credit Lenders hereby agree that each of the Existing Letters of
Credit shall, on and after the Closing Date, be deemed for all purposes of this Agreement to be a Letter of Credit issued and outstanding under the terms of this Agreement. Each Issuing Bank agrees, on the terms and conditions hereinafter set forth,
to issue letters of credit (the “Letters of Credit”) in U.S. dollars for the account of the Borrower from time to time on any Business Day during the period from the date hereof until five Business Days before the Termination
Date (A) in an Available Amount for each such Letter of Credit not to exceed at any time the Unused Revolving Credit Commitment of such Issuing Bank at such time and (B) in an aggregate Available Amount for all Letters of Credit not to exceed the

Letter of Credit to require renewal) later than the earlier of (x) five Business Days prior to the Termination Date and (y) one year after the date of issuance thereof, but any such Letter of Credit may by its terms be renewable annually on the

any Letter of Credit Advances resulting from drawings thereunder pursuant to Section 2.03(b) and request the issuance of additional Letters of Credit under this Section 2.01(e)(i). 
  
 (ii) Each Letter of Credit may by its terms be renewable annually upon notice (a “Notice of
Renewal”) given to the Issuing Bank and the Administrative Agent on or prior to any date for notice of renewal set forth in such Letter of Credit but in any event at least three Business Days prior to the date of the proposed renewal of
such Letter of Credit and upon fulfillment of the applicable conditions set forth in Article III unless such Issuing Bank has notified the Borrower (with a copy to the Administrative Agent) on or prior to the date for notice of termination set forth
in such Letter of Credit but in any event at least 30 Business Days prior to the date of automatic renewal of its election not to renew such Letter of Credit (a “Notice of Termination”); provided that the terms of each
Letter of Credit that is automatically renewable annually (A) shall require the Issuing Bank to give the beneficiary of such Letter of Credit notice of any Notice of Termination, (B) shall permit such beneficiary, upon receipt of such notice, to
draw under such Letter of Credit prior to the date such Letter of Credit otherwise would have been 

  

 30 








 
automatically renewed and (C) shall not permit the expiration date (after giving effect to any renewal) of such Letter of Credit in any event to be extended
to a date later than five Business Days prior to the Termination Date. If either a Notice of Renewal is not given by the Borrower or a Notice of Termination is given by the Issuing Bank pursuant to the immediately preceding sentence, such Letter of
Credit shall expire on the date on which it otherwise would have been automatically renewed; provided, however, that in the absence of receipt of a Notice of Renewal the Issuing Bank may in its discretion, unless instructed to the
contrary by the Administrative Agent or the Borrower deem that a Notice of Renewal had been timely delivered and, in such case, a Notice of Renewal shall be deemed to have been so delivered for all purposes under this Agreement. 
  
 SECTION 2.02. Making the Advances. 
  
 (a) Except as otherwise provided in Section 2.02(b) or 2.03
and except that the Term B Borrowing shall be made on the Closing Date, each Borrowing (other than a Swing Line Borrowing) shall be made on notice, given not later than 2:00 P.M. (New York, New York time) on the third Business Day prior to the date
of the proposed Borrowing in the case of a Borrowing comprised of Eurodollar Rate Advances, or on the first Business Day prior to the date of the proposed Borrowing in the case of a Borrowing comprised of Base Rate Advances, by the Borrower to the
Administrative Agent, which shall give prompt notice thereof to each Appropriate Lender. Each notice of a Borrowing (a “Notice of Borrowing”) shall be by telephone, confirmed immediately in writing, or by telecopier, in
substantially the form of Exhibit B-1 hereto, shall be duly executed by a Responsible Officer of the Borrower, and shall specify therein: (i) the requested date of such Borrowing (which shall be a Business Day); (ii) the Facility under which such
Borrowing is requested to be made; (iii) the Type of Advances requested to comprise such Borrowing; (iv) the requested aggregate amount of such Borrowing; and (v) in the case of a Borrowing comprised of Eurodollar Rate Advances, the requested
duration of the initial Interest Period for each such Advance. Each Appropriate Lender shall, before 2:00 P.M. (New York, New York time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the
Administrative Agent at the Administrative Agent’s Account, in same day funds, such Lender’s Pro Rata Share of such Borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions
set forth in Article III, the Administrative Agent will make such funds available to the Borrower by crediting the Borrower’s Account; provided, however, that, in the case of any Revolving Credit Borrowing, the Administrative
Agent shall first make a portion of such funds equal to the aggregate principal amount of any Swing Line Advances and Letter of Credit Advances made by the Swing Line Bank or the Issuing Bank, as the case may be, and by any Revolving Credit Lender
and outstanding on the date of such Revolving Credit Borrowing, plus accrued and unpaid interest thereon to and as of such date, available to the Swing Line Bank or the Issuing Bank, as applicable, and such other Revolving Credit Lenders for
repayment of such Swing Line Advances and Letter of Credit Advances. 
  
 (b) (i) Each Swing Line Borrowing shall be made on notice, given not later than 2:00 P.M. (New York, New York time) on the date of the proposed Swing Line Borrowing, by the Borrower to the Swing Line Bank and the
Administrative Agent. Each notice of a Swing Line Borrowing (a “Notice of Swing Line Borrowing”) shall be by telephone, confirmed immediately in writing, or telecopier, shall be in substantially the form of Exhibit B-2 hereto
and duly executed by a Responsible Officer of the Borrower, and shall specify therein: (A) the requested date of such Borrowing (which shall be a Business Day); (B) the requested amount of such Borrowing; and (C) the requested maturity of such
Borrowing (which maturity shall be no later than the seventh day after 

  

 31 








 
the requested date of such Borrowing). Upon fulfillment of the applicable conditions set forth in Article III, the Swing Line Bank will make the amount
thereof available for the account of its Applicable Lending Office to the Borrower by crediting the Borrower’s Account. 
  
 (ii) Upon demand by the Swing Line Bank, with a copy of such demand to the Administrative Agent (which shall give prompt notice thereof to
each Revolving Credit Lender), each Revolving Credit Lender shall purchase from the Swing Line Bank, and the Swing Line Bank shall sell and assign to each such Revolving Credit Lender, such Revolving Credit Lender’s Pro Rata Share of such
outstanding Swing Line Borrowing as of the date of such demand, by making available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s Account for the account of the Swing Line Bank, in
same day funds, an amount equal to such Pro Rata Share. Promptly after receipt of such funds, the Administrative Agent shall transfer such funds to the Swing Line Bank at its Applicable Lending Office. Each Revolving Credit Lender hereby agrees to
purchase its Pro Rata Share of an outstanding Swing Line Borrowing on (A) the Business Day on which demand therefor is made by the Swing Line Bank so long as notice of such demand is given not later than 12:00 Noon (New York, New York time) on such
Business Day or (B) the first Business Day next succeeding such demand if notice of such demand is given after such time. The Borrower hereby agrees to each such sale and assignment. Upon any such assignment by the Swing Line Bank to any Revolving
Credit Lender of a portion of a Swing Line Borrowing, the Swing Line Bank represents and warrants to such Revolving Credit Lender that the Swing Line Bank is the legal and beneficial owner of such interest being assigned by it, but makes no other
representation or warranty and assumes no responsibility with respect to such Swing Line Borrowing, the Loan Documents or any Loan Party. If and to the extent that any Revolving Credit Lender shall not have so made its Pro Rata Share of any
applicable Swing Line Borrowing available to the Administrative Agent in accordance with the foregoing provisions of this Section 2.02(b)(ii), such Revolving Credit Lender hereby agrees to pay to the Administrative Agent forthwith on demand the
amount of its Pro Rata Share, together with interest thereon, for each day from the date of demand by the Swing Line Bank therefor until the date such amount is paid to the Administrative Agent, at the Federal Funds Rate. If such Lender shall pay to
the Administrative Agent the amount of its Pro Rata Share for the account of the Swing Line Bank on any Business Day, such amount so paid in respect of principal shall constitute a Swing Line Advance made by such Lender on such Business Day for all
purposes of this Agreement, and the outstanding principal amount of the Swing Line Advance made by the Swing Line Bank shall be reduced by such amount on such Business Day. 
  
 (iii) The obligation of each Revolving Credit Lender to purchase its Pro Rata Share of each outstanding
Swing Line Borrowing upon demand by the Swing Line Bank therefor pursuant to clause (ii) of this Section 2.02(b) shall be absolute, unconditional and irrevocable, and shall be made strictly in accordance with the terms of clause (ii) of this Section
2.02(b) under all circumstances, including, without limitation, the following circumstances: 
  
 (A) any lack of validity or enforceability of any Loan Document or any other agreement or instrument relating thereto; 
  

 32 








 (B) the existence of any claim, set-off, defense or other right that such Revolving
Credit Lender may have at any time against the Swing Line Bank, the Borrower or any other Person, whether in connection with the transactions contemplated by the Loan Documents or any unrelated transaction; 
  
 (C) the occurrence and continuance of any Default or Event
of Default; or 
  
 (D) any other circumstance or
happening whatsoever, whether or not similar to any of the foregoing. 
  
 (c) Anything in subsection (a) of this Section 2.02 to the contrary notwithstanding, (i) the Borrower may not select Eurodollar Rate Advances if the obligation of the Appropriate Lenders to make Eurodollar Rate
Advances shall then be suspended pursuant to Section 2.09 or 2.10. In addition, the Term Advances may not be outstanding as part of more than 10 separate Borrowings and the Revolving Credit Advances may not be outstanding as part of more than 10
separate Borrowings. 
  
 (d) Each Notice of
Borrowing and Notice of Swing Line Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify
each Appropriate Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article
III, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Eurodollar Rate Advance to be made by such Lender as part of such
Borrowing when such Advance, as a result of such failure, is not made on such date. A certificate of the Lender requesting compensation pursuant to this subsection (d) submitted to the Borrower by such Lender and specifying therein the amount of
such additional compensation (including the basis of calculation thereof) shall be conclusive and binding for all purposes, absent manifest error. 
  
 (e) Unless the Administrative Agent shall have received notice from an Appropriate Lender prior to the date of any Borrowing under a
Facility under which such Lender has a Commitment that such Lender will not make available to the Administrative Agent such Lender’s Pro Rata Share of such Borrowing, the Administrative Agent may assume that such Lender has made the amount of
such Pro Rata Share available to the Administrative Agent on the date of such Borrowing in accordance with subsection (a) or (b) of this Section 2.02, as applicable, and the Administrative Agent may, in reliance upon such assumption, make available
to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made the amount of such Pro Rata Share available to the Administrative Agent, such Lender and the Borrower severally agree to repay or to
pay to the Administrative Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid or paid to the
Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at such time under Section 2.07 to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall pay to the
Administrative Agent such corresponding amount, such amount so paid shall constitute such Lender’s Advance as part of such Borrowing for all purposes under this Agreement. 
  

 33 








 (f) The failure of any Lender to make the Advance to be made by it as part of any
Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other
Lender on the date of any Borrowing. 
  
 SECTION 2.03. Issuance
of and Drawings and Reimbursement Under Letters of Credit. 
  
 (a) Request for Issuance. Each Letter of Credit shall be issued upon notice, given not later than 2:00 P.M. (New York, New York time) on the fifth Business Day prior to the date of the proposed issuance of such
Letter of Credit (or such later day as the Issuing Bank in its sole discretion shall agree), by the Borrower to the Issuing Bank, which shall give to the Administrative Agent and each Revolving Credit Lender prompt notice thereof. Each notice of
issuance of a Letter of Credit (a “Notice of Issuance”) shall be by telephone, confirmed immediately in writing, or by telecopier, shall be duly executed by a Responsible Officer of the Borrower, and shall specify therein:
(i) the requested date of such issuance (which shall be a Business Day); (ii) the requested Available Amount of such Letter of Credit; (iii) the requested expiration date of such Letter of Credit (which shall comply with the requirements of Section
2.01(e)); (iv) the name and address of the proposed beneficiary of such Letter of Credit; and (v) the proposed form of such Letter of Credit, and shall be accompanied by such application and agreement for letters of credit as the Issuing Bank may
specify to the Borrower for use in connection with such requested Letter of Credit (such applications and agreements, and all similar agreements entered into in connection with an Existing Letter of Credit, a “Letter of Credit
Agreement”). If the requested form of such Letter of Credit is acceptable to the Issuing Bank in its sole discretion, the Issuing Bank will, upon fulfillment of the applicable conditions set forth in Article III, make such Letter of
Credit available to the Borrower at its office referred to in Section 8.02 or as otherwise agreed with the Borrower in connection with the issuance of such Letter of Credit. If and to the extent that the provisions of any Letter of Credit Agreement
shall conflict with this Agreement, the provisions of this Agreement shall govern. 
  
 (b) Drawing and Reimbursement. 
  
 (i) The obligation of the Borrower to reimburse the Issuing Bank for each payment made by the Issuing Bank under any Letter of Credit, and
to pay interest thereon as provided herein, shall be absolute, unconditional and irrevocable, without regard to any circumstances, including, without limitation, those referred to in Section 2.04(d) below. The payment by the Issuing Bank of a draft
drawn under any Letter of Credit shall constitute for all purposes of this Agreement the making by the Issuing Bank of a Letter of Credit Advance, which shall be a Base Rate Advance, in the amount of such draft; provided that such payment
shall not be deemed a Base Rate Advance if the Borrower reimburses the Issuing Bank therefor prior to 2:00 P.M. (New York, New York time) on the date of such payment, or if such payment by the Issuing Bank is made on or after 2:00 P.M. (New York,
New York time), then prior to 2:00 P.M. (New York, New York time), on the Business Day immediately succeeding the date of such payment, together with interest thereon from the date of such payment to the date of such reimbursement at a rate per
annum equal to the sum of the Base Rate then in effect from time to time and the Applicable Margin for Base Rate Advances that are Revolving Credit Advances then in effect from time to time. Upon demand by the Issuing Bank, with a copy of such
demand to the Administrative Agent (which shall give prompt notice thereof to each Revolving Credit Lender), each Revolving Credit Lender shall purchase from the Issuing Bank, and the Issuing Bank shall sell and assign to each such Revolving 

  

 34 








 
Credit Lender, such Lender’s Pro Rata Share of such outstanding Letter of Credit Advance as of the date of such purchase, by making available for the
account of its Applicable Lending Office to the Administrative Agent for the account of the Issuing Bank, at the Administrative Agent’s Account, in same day funds, an amount equal to the portion of the outstanding principal amount of such
Letter of Credit Advance to be purchased by such Lender. Promptly after receipt thereof, the Administrative Agent shall transfer such funds to the Issuing Bank. The Borrower hereby agrees to each such sale and assignment. Each Revolving Credit
Lender agrees to purchase its Pro Rata Share of an outstanding Letter of Credit Advance on (A) the Business Day on which demand therefor is made by the Issuing Bank so long as notice of such demand is given not later than 2:00 P.M. (New York, New
York time) on such Business Day or (B) the first Business Day next succeeding such demand if notice of such demand is given after such time. Upon any such assignment by the Issuing Bank to any other Revolving Credit Lender of a portion of a Letter
of Credit Advance, the Issuing Bank represents and warrants to such other Lender that the Issuing Bank is the legal and beneficial owner of such interest being assigned by it, free and clear of any liens, but makes no other representation or
warranty and assumes no responsibility with respect to such Letter of Credit Advance, the Loan Documents or any Loan Party. If and to the extent that any Revolving Credit Lender shall not have so made the amount of such Letter of Credit Advance
available to the Administrative Agent, such Revolving Credit Lender agrees to pay to the Administrative Agent forthwith on demand such amount, together with interest thereon, for each day from the date of demand by the Issuing Bank until the date
such amount is paid to the Administrative Agent, at the Federal Funds Rate, for its account or the account of the Issuing Bank, as applicable. If such Revolving Credit Lender shall pay to the Administrative Agent such amount for the account of the
Issuing Bank on any Business Day, such amount so paid in respect of principal shall constitute a Letter of Credit Advance made by such Revolving Credit Lender on such Business Day for all purposes of this Agreement, and the outstanding principal
amount of the Letter of Credit Advance made by the Issuing Bank shall be reduced by such amount on such Business Day. 
  
 (ii) The Obligation of each Revolving Credit Lender to purchase its Pro Rata Share of each outstanding Letter of Credit Advance upon
demand by the Issuing Bank therefor pursuant to clause (i) of this Section 2.03(b) shall be absolute, unconditional and irrevocable, and shall be made strictly in accordance with the terms of clause (i) of this Section 2.03(b) under all
circumstances, including, without limitation, the following circumstances: 
  
 (A) any lack of validity or enforceability of any Loan Document, any Letter of Credit Agreement, any Letter of Credit or any other agreement or instrument relating thereto (collectively, the “L/C Related
Documents”); 
  
 (B) the existence
of any claim, set-off, defense or other right that such Revolving Credit Lender may have at any time against any beneficiary or any transferee of a Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting),
the Issuing Bank, the Borrower or any other Person, whether in connection with the transactions contemplated by the L/C Related Documents or any unrelated transaction; 
  
 (C) the occurrence and continuance of any Default or Event of Default; or 
  

 35 








 (D) any other circumstance or happening whatsoever, whether or not similar to any of the
foregoing. 
  
 (c) Failure to Make Letter of
Credit Advances. The failure of any Revolving Credit Lender to make the Letter of Credit Advance to be made by it on the date specified in Section 2.03(b) shall not relieve any other Revolving Credit Lender of its obligation hereunder to make
its Letter of Credit Advance on such date, but no Revolving Credit Lender shall be responsible for the failure of any other Revolving Credit Lender to make the Letter of Credit Advance to be made by such other Revolving Credit Lender on such date.

 SECTION 2.10. Increased Costs, Etc. 
  
 (a) If, after the date hereof, the adoption of any
applicable Requirement of Law, or any change in any applicable Requirement of Law, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency: 
  
 (i) shall subject such Lender (or its Applicable Lending
Office) to any tax, duty, or other charge with respect to any Eurodollar Rate Advances, any of its Notes, or 

  

 44 








 
its obligation to make any Eurodollar Rate Advances, or change the basis of taxation of any amounts payable to such Lender (or its Applicable Lending Office)
under this Agreement or its Note in respect of any Eurodollar Rate Advances (other than, for purposes of this Section 2.10, any such increased costs resulting from (A) Taxes or Other Taxes (as to which Section 2.13 shall govern), and (B) changes in
the basis of taxation of overall net income or overall gross income by the United States of America or the jurisdiction under the laws of which such Lender Party has its principal office or such Applicable Lending Office); 
  
 (ii) shall impose, modify, or deem applicable any reserve,
special deposit, assessment, or similar requirement relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Lender (or its Applicable Lending Office), including the Commitments of
such Lender hereunder; or 
  
 (iii) shall impose
on such Lender (or its Applicable Lending Office) or on the United States market for certificates of deposit or the London interbank market any other condition affecting this Agreement or its Note or any of such extensions of credit or liabilities
or commitments; 
  
 and the result of any of the foregoing is to
increase the cost to such Lender (or its Applicable Lending Office) of making, Converting into or maintaining any Eurodollar Rate Advances or to reduce any sum received or receivable by such Lender (or its Applicable Lending Office) under this
Agreement or its Note with respect to any Eurodollar Rate Advances, then the Borrower shall pay to such Lender on demand such amount or amounts as will compensate such Lender for such increased cost or reduction. Each Lender shall promptly notify
the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section 2.10(a) and will designate a different Applicable Lending
Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to it (other than by reason of administrative convenience or preference). Any
Lender claiming compensation under this Section 2.10(a) shall furnish to the Borrower and the Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder (including the method of calculation), which
shall be conclusive and binding, absent manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. If any Lender requests compensation by the Borrower under this Section 2.10(a), the Borrower
may, by notice to such Lender (with a copy to the Administrative Agent), suspend the obligation of such Lender to make or Convert Eurodollar Rate Advances, or to Convert Base Rate Advances into Eurodollar Rate Advances, until the event or condition
giving rise to such request ceases to be in effect (in which case the provisions of Section 2.10(e) shall be applicable); provided that such suspension shall not affect the right of such Lender to receive the compensation so requested. 

 
 (b) If, after the date hereof, any Lender shall have
determined that the adoption of any applicable Requirement of Law regarding capital adequacy or any change therein or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the
interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, has or would have the effect of reducing
the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such
adoption, change, request or 

  

 45 








 
directive (taking into consideration its policies with respect to capital adequacy), then from time to time upon demand the Borrower shall pay to such Lender
such additional amount or amounts as will compensate such Lender for such reduction. Each Lender shall promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will
entitle such Lender to compensation pursuant to this Section 2.10(b) and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of
such Lender, be otherwise disadvantageous to it. Any Lender claiming compensation under this Section 2.10(b) shall furnish to the Borrower and the Administrative Agent a statement setting forth the additional amount or amounts to be paid to it
hereunder (including the method of calculation), which shall be conclusive and binding, absent manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. 
  
 (c) If, on or prior to the first day of any Interest Period
for any Eurodollar Rate Advance, the Required Lenders at any time notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately and fairly reflect the cost to the Appropriate Lenders of
funding their Eurodollar Rate Advances for such Interest Period, the Administrative Agent shall promptly so notify the Borrower and the Appropriate Lenders, whereupon (i) each such Eurodollar Rate Advance will automatically, on the last day of the
then existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Appropriate Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify
the Borrower (promptly following notice from the Appropriate Lenders) that such Lenders have determined that the circumstances causing such suspension no longer exist. 
  
 (d) Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any
Lender or its Applicable Lending Office to make, maintain, or fund Eurodollar Rate Advances hereunder, then such Lender shall promptly notify the Borrower thereof and such Lender’s obligation to make Eurodollar Rate Advances and to Convert Base
Rate Advances into Eurodollar Rate Advances shall be suspended until such time as such Lender may again make, maintain and fund Eurodollar Rate Advances (in which case the provisions of Section 2.10(e) shall be applicable). 
  
 (e) If the obligation of any Lender to make a Eurodollar Rate
Advance or to Convert Base Rate Advances into Eurodollar Rate Advances shall be suspended pursuant to any other provision of this Section 2.10, such Lender’s suspended Eurodollar Rate Advances shall be automatically Converted into Base Rate
Advances on the last day(s) of the then current Interest Period(s) therefor (or, in the case of a Conversion required by Section 2.10(d), on such earlier date as such Lender may specify to the Borrower with a copy to the Administrative Agent) and,
unless and until such Lender gives notice as provided below that the circumstances specified in such other provision of this Section 2.10 that gave rise to such Conversion no longer exist: 
  
 (i) to the extent that such Lender’s suspended
Eurodollar Rate Advances have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Lender’s suspended Eurodollar Rate Advances shall be applied instead to its Base Rate Advances; and 

 
 (ii) all Eurodollar Rate Advances that would otherwise be
made or Converted by such Lender shall be made instead as (or shall remain as) Base Rate Advances. 
  

 46 








 If such Lender gives notice to the Borrower (with a copy to the Administrative Agent) that the
circumstances otherwise specified in this Section 2.10 that gave rise to the suspension of the making of Eurodollar Rate Advances by such Lender no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) at a
time when Eurodollar Rate Advances by other Lenders with Commitments under the same Facility are outstanding, such Lender’s Base Rate Advances shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s)
therefor, to the extent necessary into Eurodollar Rate Advances. 
  
 SECTION 2.11. Evidence of Debt. 
  
 (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the debt of the Borrower to such Lender resulting from each Advance owing to such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time hereunder. 
  
 (b) The Register maintained by the Administrative Agent pursuant to Section 8.07(c) shall include accounts for each Lender, in which
accounts (taken together) shall be recorded (i) the date and amount of each Advance made hereunder, (ii) the terms of each Assignment and Assumption delivered to and accepted by it, (iii) the amount of any principal or interest due and payable or to
become due and payable from the Borrower to each Lender hereunder and (iv) the amount of any sum received by the Administrative Agent from the Borrower hereunder and each Lender’s share thereof. 
  
 (c) The entries made as provided in this Section 2.11 shall
be conclusive and binding for all purposes, absent manifest error. 
  
 SECTION 2.12. Payments and Computations. 
  
 (a) The Borrower shall make each payment hereunder and under the Notes, irrespective of any right of counterclaim, deduction or set-off (except as otherwise provided in Section 2.16), not later than 2:00 P.M. (New
York, New York time) on the day when due in U.S. dollars to the Administrative Agent at the Administrative Agent’s Account in same day funds, with payments received by the Administrative Agent after such time being deemed to have been received
on the next succeeding Business Day. The Administrative Agent will promptly thereafter cause like funds to be distributed (i) if such payment by the Borrower is in respect of principal, interest, commitment fees or any other Obligation then due and
payable hereunder and under the Notes to more than one Lender Party, to such Lender Parties for the accounts of their respective Applicable Lending Offices in accordance with their respective Pro Rata Shares of the amounts of such respective
Obligations due and payable to such Lender Parties at such time and (ii) if such payment by the Borrower is in respect of any Obligation then due and payable hereunder solely to one Lender Party, to such Lender Party for the account of its
Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information contained therein in the Register pursuant to Section 8.07(c),
from and after the effective date of such Assignment and Assumption, the Administrative Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender Party assignee thereunder, and the parties
to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves. 
  

 47 








 (b) The Borrower hereby authorizes each Lender Party, if and to the extent payment owed
to such Lender Party is not made when due hereunder or, in the case of a Lender, under the Note held by such Lender, to charge from time to time against any or all of the Borrower’s accounts with such Lender Party any amount so due. 

 
 (c) All computations of interest based on the Base Rate
shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate and of the letter of credit commissions and commitment
or letter of credit fees payable hereunder shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for
which such interest, fees or commissions are payable. Each determination by the Administrative Agent of an interest rate, fee or commission hereunder shall be conclusive and binding for all purposes, absent manifest error. 
  
 (d) Whenever any payment hereunder or under the Notes shall
be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest, letter of credit commissions
or commitment or letter of credit fees, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next succeeding calendar month, such
payment shall be made on the immediately preceding Business Day. 
  
 (e) Unless the Borrower or any Lender Party has notified the Administrative Agent prior to the date any payment is required to be made by it to the Administrative Agent hereunder, that the Borrower or such Lender
Party, as the case may be, will not make such payment, the Administrative Agent may assume that the Borrower or such Lender Party, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make
available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then: 
  
 (i) if the Borrower failed to make such payment, each Lender
Party shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender Party in immediately available funds, together with interest thereon in respect of each day from and
including the date such amount was made available by the Administrative Agent to such Lender Party to the date such amount is repaid to the Administrative Agent in immediately available funds, at the Federal Funds Rate from time to time in effect;
and 
  
 (ii) if any Lender Party failed to make
such payment, such Lender Party shall forthwith on demand pay to the Administrative Agent the amount thereof in immediately available funds, together with interest thereon for the period from the date such amount was made available by the
Administrative Agent to the Borrower to the date such amount is recovered by the Administrative Agent (the “Compensation Period”) at a rate per annum equal to the Federal Funds Rate from time to time in effect. If such Lender
Party pays such amount to the Administrative Agent, then such amount shall constitute such Lender Party’s Advance included in the applicable Borrowing. If such Lender Party does not pay such amount forthwith upon the Administrative Agent’s
demand therefor, the Administrative Agent may make a demand therefor upon the Borrower, and the Borrower shall pay such amount to the Administrative Agent, together with interest thereon for the 

  

 48 








 
Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing herein shall be deemed to relieve any
Lender Party from its obligation to fulfill its applicable Commitment or to prejudice any rights which the Administrative Agent or the Borrower may have against any Lender Party as a result of any default by such Lender Party hereunder. 

 
 A notice from the Administrative Agent to any Lender Party with respect to
any amount owing under this subsection (e) shall be conclusive, absent manifest error. 
  
 (f) Whenever any payment received by the Administrative Agent under this Agreement or any of the other Loan Documents is insufficient to
pay in full all amounts due and payable to the Agents and the Lender Parties under or in respect of this Agreement and the other Loan Documents on any date, such payment shall be distributed by the Administrative Agent and applied by the Agents and
the Lender Parties in the following order of priority: 
  
 (i) first, to the payment of all of the fees, indemnification payments, costs and expenses that are due and payable to the Agents (solely in their respective capacities as Agents) under or in respect of this Agreement and the other
Loan Documents on such date, ratably based upon the respective aggregate amounts of all such fees, indemnification payments, costs and expenses owing to the Agents on such date; 
  
 (ii) second, to the payment of all of the fees, indemnification payments, costs and expenses that are
due and payable to the Issuing Bank and the Swing Line Bank (solely in their respective capacities as such) under or in respect of this Agreement and the other Loan Documents on such date, ratably based upon the respective aggregate amounts of all
such fees, indemnification payments, costs and expenses owing to the Issuing Bank and the Swing Line Bank on such date; 
  
 (iii) third, to the payment of all of the indemnification payments, costs and expenses that are due and payable to the Lenders
under Section 8.04 hereof, Section 12 of the Subsidiary Guarantee, Section 21 of the Security Agreement and any similar section of any of the other Loan Documents on such date, ratably based upon the respective aggregate amounts of all such
indemnification payments, costs and expenses owing to the Lenders on such date; 
  
 (iv) fourth, to the payment of all of the amounts that are due and payable to the Administrative Agent and the Lender Parties under
Sections 2.10 and 2.13 hereof and Section 5 of the Subsidiary Guarantee on such date, ratably based upon the respective aggregate amounts thereof owing to the Administrative Agent and the Lender Parties on such date; 
  
 (v) fifth, to the payment of all of the accrued and
unpaid interest on the Obligations of the Borrower under or in respect of the Loan Documents that is due and payable to the Administrative Agent and the Lender Parties under Section 2.07(a) on such date and all of the fees that are due and payable
to the Lenders or the Issuing Bank under Section 2.08(a) or 2.08(b) on such date, ratably based upon the respective aggregate Commitments of the Lenders under the Facilities on such date; 
  
 (vi) sixth, to the payment of the principal amount of
all of the outstanding Advances that is due and payable to the Administrative Agent and the Lender Parties on 

  

 49 








 
such date, ratably based upon the respective aggregate amounts of all such principal owing to the Administrative Agent and the Lender Parties on such date;
and 
  
 (vii) seventh, to the payment of
all other Obligations of the Loan Parties owing under or in respect of the Loan Documents that are due and payable to the Administrative Agent and the other Secured Parties on such date, ratably based upon the respective aggregate amounts of all
such Obligations owing to the Administrative Agent and the other Secured Parties on such date. 
  
 If the Administrative Agent receives funds for application to the Obligations of the Loan Parties under or in respect of the Loan Documents under circumstances for which the Loan Documents do not specify the Advances
or the Facility to which, or the manner in which, such funds are to be applied, the Administrative Agent may, but shall not be obligated to, elect to distribute such funds to each of the Lender Parties in accordance with such Lender Party’s Pro
Rata Share of the sum of (A) the aggregate principal amount of all Advances outstanding at such time and (b) the aggregate Available Amount of all Letters of Credit outstanding at such time, in repayment or prepayment of such of the outstanding
Advances or other Obligations then owing to such Lender Party, and, in the case of the Term Facility, for application to such principal repayment installments thereof, as the Administrative Agent shall direct. 
  
 SECTION 2.13. Taxes. 
  
 (a) Any and all payments by the Borrower to or for the
account of any Lender Party or any Agent hereunder or under any other Loan Document shall be made, in accordance with Section 2.12 or the applicable provisions of such other Loan Document, if any, free and clear of and without deduction for any and
all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender Party and each Agent, taxes that are imposed on its overall net income by the
United States and taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction under the laws of which such Lender Party or such Agent, as the case may be, is organized or is a
resident, or has a fixed place of business or a permanent establishment, or any political subdivision of any of the foregoing, and, in the case of each Lender Party, taxes that are imposed on its overall net income (and franchise taxes imposed in
lieu thereof) by the state or foreign jurisdiction of either of its Applicable Lending Offices or any political subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of
payments hereunder or under the Notes being, collectively, “Taxes”). If the Borrower shall be required under applicable Requirements of Law to deduct any Taxes from or in respect of any sum payable hereunder or under any
other Loan Document to any Lender Party or any Agent, (i) the sum payable by the Borrower shall be increased as necessary so that after the Borrower and the Administrative Agent have been made all required deductions (including deductions applicable
to additional sums payable under this Section 2.13) such Lender Party or such Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii)
the Borrower shall pay the full amount deducted to the relevant taxation authority or other Governmental Authority in accordance with applicable Requirements of Law and (iv) within 30 days after the date of any payment of Taxes, the Borrower shall
furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof, to the extent such a receipt is issued therefor, or other written proof of payment thereof
that is reasonably satisfactory to the Administrative Agent. 
  

 50 








 (b) In addition, the Borrower agrees to pay any present or future stamp, recording or
documentary, excise, property or similar taxes, charges or levies that arise from any payment made hereunder or under any other Loan Document or from the execution, delivery of, or registration of, any performance under, or otherwise with respect
to, this Agreement or any other Loan Document (collectively, “Other Taxes”). 
  
 (c) The Borrower shall indemnify each of the Lender Parties and each of the Agents for, and hold each of them harmless against, the full
amount of Taxes and Other Taxes, and the full amount of taxes of any kind imposed by any jurisdiction on amounts payable under this Section 2.13, imposed on or paid by such Lender Party or such Agent, as the case may be, and any liability (including
penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. The indemnity by the Borrower provided for in this subsection (c) shall apply and be made whether or not the Taxes or Other Taxes for which
indemnification hereunder is sought have been correctly or legally asserted; provided, however, that such Lender or such Agent seeking such indemnification shall take all reasonable actions (consistent with its internal policy and legal and
regulatory restrictions) requested by the Borrower to assist the Borrower in recovering the amounts paid thereby pursuant to this subsection (c) from the relevant taxation authority or other Governmental Authority. Amounts payable by the Borrower
under the indemnity set forth in this subsection (c) shall be paid within 30 days from the date on which the applicable Lender or Agent, as the case may be, makes written demand therefor (including the method of calculation). 
  
 (d) In the case of any payment hereunder or under any other
Loan Document by or on behalf of the Borrower through an account or branch outside the United States, or on behalf of the Borrower by a payor that is not a United States person, if the Borrower determines that no Taxes are payable in respect
thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at its address referred to in Section 8.02, an opinion of counsel reasonably acceptable to the Administrative Agent stating that such payment is
exempt from Taxes. For purposes of this subsection (d) and subsection (e) of this Section 2.13, the terms “United States” and “United States person” shall have the meanings specified in Section 7701 of
the Internal Revenue Code. 
  
 (e) Each Lender
Party organized under the laws of a jurisdiction outside the United States shall, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender, the Swing Line Bank or the Initial Issuing Bank, as the
case may be, and on or prior to the date of the Assignment and Assumption pursuant to which it becomes a Lender Party in the case of each other Lender Party, and from time to time thereafter as reasonably requested in writing by the Borrower (but
only so long thereafter as such Lender Party remains lawfully able to do so), provide each of the Administrative Agent and the Borrower with two original Internal Revenue Service forms W-8BEN, W-8ECI or W-8IMY, or in the case of a Lender Party that
has certified in writing to the Administrative Agent that it is claiming exemption from United States withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code with respect to payments of “portfolio interest” from
W-8BEN), (and, if such Lender Party delivers a form W-8BEN, a certificate representing that such Lender Party is not (i) a “bank” for purposes of Section 881(c) of the Internal Revenue Code, (ii) a ten-percent shareholder (within
the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of the Borrower or (iii) a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Internal Revenue Code)), as appropriate, or any
successor or other form prescribed by the Internal Revenue Service, certifying that such Lender Party is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or any other Loan Document or,
in the case of a Lender Party providing a form W- 

  

 51 








 
8BEN, certifying that such Lender Party is a foreign corporation, partnership, estate or trust. If any such forms provided by a Lender Party at the time such
Lender Party first becomes a party to this Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender Party provides the
appropriate form certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes solely for the periods governed by such forms. However, if at the date of the Assignment and
Assumption pursuant to which a Lender Party becomes a party to this Agreement, the Lender Party assignor was entitled to payments under subsection (a) of this Section 2.13 in respect of United States withholding tax with respect to interest paid at
such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the
Lender Party assignee on such date. None of the Lender Parties shall be entitled to payment pursuant to subsection (a) or (c) of this Section 2.13 with respect to any additional Taxes that result solely and directly from a change in either of the
Applicable Lending Offices of such Lender Party (other than any such additional Taxes that are imposed as a result of a change in the applicable Requirements of Law, or in the interpretation of application thereof, occurring after the date of
such change), unless such change is made pursuant to the terms of Section 2.10(e) or subsection (g) of this Section 2.13 or as a result of a request therefor by the Borrower. 
  
 (f) For any period with respect to which a Lender Party has failed to provide the Borrower with the
appropriate form, certificate or other document described in subsection (e) of this Section 2.13 (other than if such failure is due to a change in the applicable Requirements of Law, or in the interpretation or application thereof, occurring
after the date on which a form, certificate or other document originally was required to be provided or if such form, certificate or other document otherwise is not required under subsection (e) of this Section 2.13), such Lender Party shall not be
entitled to indemnification under subsection (a) or (c) of this Section 2.13 with respect to Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender Party become subject to Taxes because of
its failure to deliver a form, certificate or other document required hereunder, the Borrower shall take such steps as such Lender Party shall reasonably request to assist such Lender Party in recovering such Taxes. 
  
 (g) Each of the Lender Parties hereby agrees that, upon the
occurrence of any circumstances entitling such Lender Party to additional amounts pursuant to this Section 2.13, such Lender Party shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate
a different Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender Party, be
otherwise disadvantageous to such Lender Party (other than by reason of administrative convenience or preference). 
  
 SECTION 2.14. Sharing of Payments, Etc. If any Lender Party shall obtain at any time any payment (whether voluntary, involuntary, through the
exercise of any right of setoff, or otherwise) (a) on account of Obligations due and payable to such Lender Party under or in respect of this Agreement or any of the other Loan Documents at such time in excess of its ratable share (according to the
proportion of (i) the amount of such Obligations due and payable to such Lender Party at such time (other than pursuant to Section 2.10, 2.13, 8.04 or 8.07) to (ii) the aggregate amount of the Obligations due and payable to all Lender Parties at
such time) of payments on account of the Obligations due and payable to all Lender Parties under or in respect of this Agreement and the other Loan Documents at such time obtained by all the Lender Parties at such time or (b) on account of
Obligations owing (but not due and payable) to such Lender Party under or in respect of this Agreement or any of the other Loan Documents at such time in 

  

 52 








 
excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing to such Lender Party at such time (other than pursuant
to Section 2.10, 2.13, 8.04 or 8.07) to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lender Parties under or in respect of this Agreement and the other Loan Documents at such time) of payments on account of the
Obligations owing (but not due and payable) to all Lender Parties under or in respect of this Agreement and the other Loan Documents at such time obtained by all of the Lender Parties at such time, such Lender Party shall forthwith purchase from the
other Lender Parties such interests or participating interests in the Obligations due and payable or owing to them, as the case may be, as shall be necessary to cause such purchasing Lender Party to share the excess payment ratably with each of
them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender Party, such purchase from each other Lender Party shall be rescinded and such other Lender Party shall repay to the
purchasing Lender Party the purchase price to the extent of such Lender Party’s ratable share (according to the proportion of (A) the purchase price paid to such Lender Party to (B) the aggregate purchase price paid to all Lender Parties) of
such recovery, together with an amount equal to such Lender Party’s ratable share (according to the proportion of (1) the amount of such other Lender Party’s required repayment to (2) the total amount so recovered from the purchasing
Lender Party) of any interest or other amount paid or payable by the purchasing Lender Party in respect of the total amount so recovered; provided further that, so long as the Obligations under the Loan Documents shall not have been
accelerated, any excess payment received by any Appropriate Lender shall be shared on a pro rata basis only with other Appropriate Lenders. The Borrower hereby agrees that any Lender Party so purchasing an interest or participating interest from
another Lender Party pursuant to this Section 2.14 may, to the fullest extent permitted under applicable law, exercise all its rights of payment (including the right of setoff) with respect to such an interest or participating interest, as the case
may be, as fully as if such Lender Party were the direct creditor of the Borrower in the amount of such an interest or participating interest. 
  
 SECTION 2.15. Use of Proceeds. The proceeds of the Term A Advances were used as provided in the Existing Credit Agreement. The proceeds of the Term
B Advances will be used to repay the principal amount of the term loans made by the Existing Term B Lenders under the Existing Credit Agreement and for general corporate purposes, and the proceeds of the Revolving Credit Advances shall be available
(and the Borrower agrees that it shall use such proceeds) solely for acquisitions as permitted herein and for general corporate purposes of the Borrower and its subsidiaries. 
  
 SECTION 2.16. Defaulting Lenders. 
  
 (a) In the event that, at any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such
Defaulting Lender shall owe a Defaulted Advance to the Borrower and (iii) the Borrower shall be required to make any payment hereunder or under any other Loan Document to or for the account of such Defaulting Lender, then the Borrower may, so long
as no Default shall occur or be continuing at such time and to the fullest extent permitted by applicable law, set off and otherwise apply the Obligation of the Borrower to make such payment to or for the account of such Defaulting Lender against
the obligation of such Defaulting Lender to make such Defaulted Advance. In the event that, on any date, the Borrower shall so set off and otherwise apply its obligation to make any such payment against the obligation of such Defaulting Lender to
make any such Defaulted Advance on or prior to such date, the amount so set off and otherwise applied by the Borrower shall constitute for all purposes of this Agreement and the other Loan Documents an Advance by such Defaulting Lender made on the
date of such setoff under the Facility pursuant to which such Defaulted Advance was originally required to have been made pursuant to Section 2.01. Such Advance shall be a Base Rate Advance and shall be considered, for all purposes of this
Agreement, to comprise part of the Borrowing in connection with which such Defaulted Advance was originally required to have been made pursuant to Section 2.01, 

  

 53 








 
even if the other Advances comprising such Borrowing shall be Eurodollar Rate Advances on the date such Advance is deemed to be made pursuant to this
subsection (a). The Borrower shall notify the Administrative Agent at any time the Borrower exercises its right of set-off pursuant to this subsection (a) and shall set forth in such notice (A) the name of the Defaulting Lender and the Defaulted
Advance required to be made by such Defaulting Lender and (B) the amount set off and otherwise applied in respect of such Defaulted Advance pursuant to this subsection (a). Any portion of such payment otherwise required to be made by the Borrower to
or for the account of such Defaulting Lender which is paid by the Borrower, after giving effect to the amount set off and otherwise applied by the Borrower pursuant to this subsection (a), shall be applied by the Administrative Agent as specified in
subsection (b) or (c) of this Section 2.16. 
  
 (b) In the event that, at any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such Defaulting Lender shall owe a Defaulted Amount to the Administrative Agent or any of the other Lender Parties and (iii) the Borrower shall
make any payment hereunder or under any other Loan Document to the Administrative Agent for the account of such Defaulting Lender, then the Administrative Agent may, on its behalf or on behalf of such other Lender Parties and to the fullest extent
permitted by applicable law, apply at such time the amount so paid by the Borrower to or for the account of such Defaulting Lender to the payment of each such Defaulted Amount to the extent required to pay such Defaulted Amount. In the event that
the Administrative Agent shall so apply any such amount to the payment of any such Defaulted Amount on any date, the amount so applied by the Administrative Agent shall constitute for all purposes of this Agreement and the other Loan Documents
payment, to such extent, of such Defaulted Amount on such date. Any such amount so applied by the Administrative Agent shall be retained by the Administrative Agent or distributed by the Administrative Agent to such other Lender Parties, ratably in
accordance with the respective portions of such Defaulted Amounts payable at such time to the Administrative Agent and such other Lender Parties and, if the amount of such payment made by the Borrower shall at such time be insufficient to pay all
Defaulted Amounts owing at such time to the Administrative Agent and the other Lender Parties, in the following order of priority: 
  
 (A) first, to the Administrative Agent for any Defaulted Amount then owing to the Administrative Agent; 
  
 (B) second, to the Issuing Bank and the Swing Line
Bank for any Defaulted Amount then owing to them, in their capacities as such, ratably in accordance with such respective Defaulted Amounts then owing to such Issuing Bank and such Swing Line Bank; and 
  
 (C) third, to any other Lender Parties for any
Defaulted Amounts then owing to such other Lender Parties, ratably in accordance with such respective Defaulted Amounts then owing to such other Lender Parties. 
  

Any portion of such amount paid by the Borrower for the account of such Defaulting Lender remaining, after giving effect to the amount applied by the
Administrative Agent pursuant to this subsection (b), shall be applied by the Administrative Agent as specified in subsection (c) of this Section 2.16. 
  
 (c) In the event that, at any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such Defaulting Lender shall not owe a
Defaulted Advance or a Defaulted Amount and (iii) the Borrower, the Administrative Agent or any other Lender Party shall be required to pay or distribute any amount hereunder or under any other Loan Document to or for the account 
  

 54 








 
of such Defaulting Lender, then the Borrower or such other Lender Party shall pay such amount to the Administrative Agent to be held by the Administrative
Agent, to the fullest extent permitted by applicable law, in escrow or the Administrative Agent shall, to the fullest extent permitted by applicable law, hold in escrow such amount otherwise held by it. Any funds held by the Administrative Agent in

permitted by applicable law, apply all funds so held in escrow from time to time to the extent necessary to make any Advances required to be made by such Defaulting Lender and to pay any amount payable by such Defaulting Lender hereunder and under
the other Loan Documents to the Administrative Agent or any other Lender Party, as and when such Advances or amounts are required to be made or paid and, if the amount so held in escrow shall at any time be insufficient to make and pay all such
Advances and amounts required to be made or paid at such time, in the following order of priority: 
  
 (A) first, to the Administrative Agent for any amount then due and payable by such Defaulting Lender to the Administrative Agent
hereunder; 
  
 (B) second, to the Issuing
Bank and the Swing Line Bank for any amounts then due and payable to them hereunder, in their capacities as such, by such Defaulting Lender, ratably in accordance with such amounts then due and payable to such Issuing Bank and such Swing Line Bank;

  
 (C) third, to any other Lender Parties
for any amount then due and payable by such Defaulting Lender to such other Lender Parties hereunder, ratably in accordance with such respective amounts then due and payable to such other Lender Parties; and 
  
 (D) fourth, to the Borrower for any Advance then
required to be made by such Defaulting Lender pursuant to a Commitment of such Defaulting Lender. 
  
 In the event that any Lender Party that is a Defaulting Lender shall, at any time, cease to be a Defaulting Lender, any funds held by the Administrative
Agent in escrow at such time with respect to such Lender Party shall be distributed by the Administrative Agent to such Lender Party and applied by such Lender Party to the Obligations owing to such Lender Party at such time under this Agreement and
the other Loan Documents ratably in accordance with the respective amounts of such Obligations outstanding at such time. 
  
 (d) The rights and remedies against a Defaulting Lender under this Section 2.16 are in addition to other rights and remedies that the
Borrower may have against such Defaulting Lender with respect to any Defaulted Advance and that the Administrative Agent or any Lender Party may have against such Defaulting Lender with respect to any Defaulted Amount.

and in good standing (if such concept is applicable) under the laws of the jurisdiction of its organization, (ii) is duly qualified and in good standing as a foreign business enterprise (if such concept is applicable) in each other jurisdiction in
which it owns or leases property or in which the conduct of its business requires it to so qualify or be licensed except where the failure to be so qualified or licensed would not result in a Material Adverse Effect and (iii) has all requisite power
and authority (including, without limitation, all material Governmental Authorizations) to own or lease and operate its properties and to carry on its business as now conducted and as proposed to be conducted. 
  
 (b) Set forth on Schedule 4.01(b) hereto is a complete and

outstanding, on the date hereof and the percentage of each such class of its Equity Interests owned (directly or indirectly) by the Borrower or any Subsidiary thereof and the number of shares or other units covered by all outstanding options,
warrants, rights of conversion or purchase and similar rights at the date hereof, except for any obligations or rights of the Borrower or any of its Subsidiaries to acquire any minority interest in any Subsidiary of the Borrower that is a

owned by the Borrower or one or more of its Subsidiaries, free and clear of all Liens, except those created under the Collateral Documents or Permitted Liens. 
  

(c) The execution, delivery and performance by each Loan Party of each Loan Document to which it is or is to be a party, and the

or imposition of any Lien upon or with respect to any of the properties of any Loan Party. No Loan Party is in violation of any such Requirements of Law or in breach of any such contract, loan agreement, indenture, mortgage, deed of trust, lease or
other instrument, the violation or breach of which would be reasonably likely to have a Material Adverse Effect. 
  
 (d) No Governmental Authorization, and no other authorization or approval or other action by, and no notice to or filing with, any
Governmental Authority or any other third party is required for (i) the due execution, delivery, recordation, filing or performance by any Loan Party of any Loan Document to which it is or is to be a party, or for the consummation of the
Transaction, (ii) the grant by any Loan Party of the Liens granted by it pursuant to the Collateral Documents, (iii) the perfection or maintenance of the Liens created under the Collateral Documents on such of the Collateral located in the United

creation or perfection of the Liens and security interests contemplated by the Loan Documents and (C) the actions required by laws generally with respect to the exercise by secured creditors of their rights and remedies. All applicable waiting
periods in connection with the Transaction have expired without any action having been taken by any competent authority restraining, preventing or imposing materially adverse conditions upon the Transaction or the rights of the Loan Parties or their
Subsidiaries freely to transfer or otherwise dispose of, or to create any Lien on, any properties now owned or hereafter acquired by any of them. 
  
 (e) This Agreement has been, and each other Loan Document when delivered hereunder will have been, duly executed and delivered by each
Loan Party thereto. This Agreement is, and each other Loan Document when delivered hereunder will be, the legal, valid and binding obligation of each Loan Party thereto, enforceable against such Loan Party in accordance with its terms. 

 
 (f) There is no action, suit, investigation, litigation or
proceeding affecting any Loan Party or any of its Subsidiaries, including any Environmental Action, pending or, to the knowledge of the Borrower, threatened before any Governmental Authority or arbitrator that (i) could be reasonably likely to have
a Material Adverse Effect or (ii) purports to affect the legality, validity or enforceability of any Loan Document or the consummation of the Transaction, except as described on Schedule 4.01(f) hereto or disclosed prior to the Closing Date in the
Borrower’s filings made with the Securities and Exchange Commission. 
  
 (g) (i) The Consolidated balance sheet of the Borrower and its Subsidiaries as at December 31, 2002, and the related Consolidated statement of income and Consolidated statement of cash flows of the Borrower and its
Subsidiaries for the fiscal year then ended, accompanied by an unqualified opinion of KPMG LLP, independent public accountants, copies of which have been furnished to each Lender Party, fairly present the Consolidated financial condition of the
Borrower and its Subsidiaries as at such date and the Consolidated results of operations of the Borrower and its Subsidiaries for the period ended on such date, all in accordance with generally accepted accounting principles applied on a consistent
basis, and (ii) since December 31, 2002, there has been no Material Adverse Change. 
  
 (h) The Consolidated forecasted balance sheet, statement of income and statement of cash flows of the Borrower and its Subsidiaries
delivered to the Lender Parties pursuant to Section 3.01(a)(vi) or Section 5.03 were prepared in good faith on the basis of the assumptions stated therein, which assumptions were believed to be reasonable in light of the conditions existing at the
time of delivery of such forecasts, and represented, at the time of delivery, the Borrower’s best estimate of its future financial performance. 
  
 (i) Neither the Information Memorandum nor any other information, exhibit or report furnished by any Loan Party to any Agent or any Lender
Party in connection with the negotiation and syndication of the Loan Documents or pursuant to the terms of the Loan Documents contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements made
therein not misleading. 
  
 (j) The Borrower is
not engaged in the business of extending credit for the purpose of purchasing or carrying Margin Stock, and no proceeds of any Advance or drawings under any Letter of Credit will be used to purchase or carry any Margin Stock or to extend credit to
others 

  

 60 








 
for the purpose of purchasing or carrying any Margin Stock, except for the purchase by the Borrower of its common stock as contemplated in Sections
5.02(g)(v) and (vi). 
  
 (k) Neither any Loan
Party nor any of its Subsidiaries is an “investment company”, or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment company”, as such terms are defined in the
Investment Company Act of 1940, as amended. Neither any Loan Party nor any of its Subsidiaries is a “holding company”, or a “subsidiary company” of a “holding company”, or an “affiliate” of a “holding
company” or of a “subsidiary company” of a “holding company”, as such terms are defined in the Public Utility Holding Company Act of 1935, as amended. Neither the making of any Advances, nor the issuance of any Letters of
Credit, nor the application of the proceeds or repayment thereof by the Borrower, nor the consummation of the other transactions contemplated by the Loan Documents and Related Documents, will violate any provision of any such Act or any rule,
regulation or order of the Securities and Exchange Commission thereunder. 
  
 (l) Upon making of the filings and taking of the other actions necessary to create, perfect and protect the security interest in the Collateral created under the Collateral Documents, the Collateral Documents create
in favor of the Administrative Agent for the benefit of the Secured Parties a valid and, together with such filings and other actions, perfected first priority security interest in the Collateral, securing the payment of the Secured Obligations,
subject to Permitted Liens. The Loan Parties are the legal and beneficial owners of the Collateral free and clear of any Lien, except for the liens and security interests created or permitted under the Loan Documents. 
  
 (m) Each Loan Party is, individually and together with its
Subsidiaries, Solvent.

ERISA Event has occurred or is reasonably expected to occur with respect to any Plan that has resulted in or is reasonably expected to result in a material liability of any Loan Party or any ERISA Affiliate. 
  
 (ii) Schedule B (Actuarial Information) to the most recent
annual report (Form 5500 Series) for each Plan, copies of which have been filed with the Internal Revenue Service and furnished to the Lender Parties, is complete and accurate and fairly presents the funding status of such Plan, and since the date
of such Schedule B there has been no material adverse change in such funding status. 
  
 (iii) Neither any Loan Party nor any ERISA Affiliate has incurred or is reasonably expected to incur any Withdrawal Liability exceeding
$100,000 to any Multiemployer Plan.

is reasonably expected to be in reorganization or to be terminated, within the meaning of Title IV of ERISA. 
  
 (o) Except as described on Schedule 4.01(o) hereto: 
  
 (i) The operations and properties of each Loan Party comply in all material respects with all applicable
Environmental Laws and Environmental Permits, except where any such failure to comply would not be reasonably expected to have a Material 

  

 61 








 
Adverse Effect, all past non-compliance with such Environmental Laws and Environmental Permits has been resolved without ongoing obligations or costs, except
where any such failure to comply would not be reasonably expected to have a Material Adverse Effect and, to Borrower’s knowledge, no circumstances exist that could be reasonably likely to (A) form the basis of an Environmental Action against
any Loan Party or any of their properties that could have a Material Adverse Effect or (B) cause any such property to be subject to any restrictions on ownership, occupancy, use or transferability under any Environmental Law.

Authority or the requirements of any Environmental Law; and all Hazardous Materials generated, used, treated, handled or stored at, or transported to or from, any property currently or formerly owned or operated by any Loan Party have been disposed
of in a manner not reasonably expected to result in liability to any Loan Party that, individually or in the aggregate, would have a Material Adverse Effect.

L/C Cash Collateral Account an amount equal to such aggregate Available Amount. If at any time the Administrative Agent determines that any funds held in the L/C Cash Collateral Account are subject to any right or claim of any Person other than the
Secured Parties or that the total amount of such funds is less than the aggregate Available Amount of all Letters of Credit, the Borrower will, forthwith upon demand by the Administrative Agent, pay to the Administrative Agent, as additional funds
to be deposited and held in the L/C Cash Collateral Account, an amount equal to the excess of (a) such aggregate Available Amount over (b) the total amount of funds, if any, then held in the L/C Cash Collateral Account that the Administrative Agent
determines to be free and clear of any such right and claim. Upon the drawing of any Letter of Credit for which funds are on deposit in the L/C Cash Collateral Account, such funds shall be applied to reimburse the Issuing Bank or Revolving Credit
Lenders, as applicable, in the manner provided for in the Security Agreement and to the extent permitted by applicable law.

 THE AGENTS 
  
 SECTION 7.01. Appointment, Powers and Immunity. 
  
 (a) Each Lender Party (in its capacities as a Lender, the Swing Line Bank (if applicable), the Issuing Bank (if applicable) and on behalf of itself and its Affiliates as potential 

  

 86 








 
Hedge Banks) hereby appoints and authorizes the Administrative Agent to act as its agent under this Agreement and the other Loan Documents with such powers
and discretion as are specifically delegated to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. The Administrative Agent (which term as used
in this sentence and in Section 7.05(a) and Section 7.06 shall include its affiliates and its own and its affiliates’ officers, directors, employees, and agents): (i) shall not have any duties or responsibilities except those expressly set
forth in this Agreement and shall not be a trustee or fiduciary for any Lender Party; (ii) shall not be responsible to the Lender Parties for any recital, statement, representation, or warranty (whether written or oral) made in or in connection with
any Loan Document or any certificate or other document referred to or provided for in, or received by any of them under, any Loan Document, or for the value, validity, effectiveness, genuineness, enforceability, or sufficiency of, or the perfection
or priority of any lien or security interest created or purported to be created under or in connection with, any Loan Document, or any other document referred to or provided for therein or for any failure by any Loan Party or any other Person to
perform any of its obligations thereunder; (iii) shall not be responsible for or have any duty to ascertain, inquire into, or verify the performance or observance of any covenants or agreements by any Loan Party or the satisfaction of any condition
or to inspect the property (including the books and records) of any Loan Party or any of its Subsidiaries or Affiliates; (iv) shall not be required to initiate or conduct any litigation or collection proceedings under any Loan Document; and (v)
shall not be responsible for any action taken or omitted to be taken by it or any of its directors, officers, agents or employees under or in connection with any Loan Document, except for its or their own gross negligence or willful misconduct.

  
 (b) The Administrative Agent shall also act
as the “collateral agent” under the Loan Documents, and each of the Lender Parties (in its capacities as a Lender, the Swing Line Bank (if applicable), Issuing Bank (if applicable) hereby appoints and authorizes the Administrative
Agent to act as the agent of such Lender Party for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Loan Parties to secure any of the Secured Obligations, together with such powers and discretion as
are reasonably incidental thereto. The Administrative Agent may from time to time in its discretion appoint any of the other Lender Parties or any of the affiliates of a Lender Party to act as its co-agent or sub-agent or its attorney-in-fact for
any purpose, including for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Collateral Documents or of exercising any rights and remedies thereunder at the direction of the Administrative Agent,
and the Administrative Agent shall not be responsible for the negligence or misconduct of any such co-agents, sub-agents or attorneys-in-fact selected by it with reasonable care. In this connection, the Administrative Agent, as “collateral
agent”, and such co-agents, sub-agents and attorneys-in-fact shall be entitled to the benefits of all provisions of this Article VII (including, without limitation, Section 7.05, as though such co-agents, sub-agents and attorneys-in-fact were
the “collateral agent” under the Loan Documents) as if set forth in full herein with respect thereto. 
  
 (c) The Book Managers, the Documentation Agents and the Syndication Agents shall not have any powers or discretion under this Agreement or
any of the other Loan Documents other than those bestowed upon it as a co-agent or sub-agent from time to time by the Administrative Agent pursuant to subsection (b) of this Section 7.01, and each of the Lender Parties hereby acknowledges that the
Book Managers, the Documentation Agents and the Syndication Agents shall not have any liability under this Agreement or any of the other Loan Documents. 
  

 87 








 SECTION 7.02. Reliance by Agent. The Administrative Agent shall be entitled to rely upon any
certification, notice, instrument, writing, or other communication (including, without limitation, any thereof by telephone or telecopy) believed by it to be genuine and correct and to have been signed, sent or made by or on behalf of the proper
Person or Persons, and upon advice and statements of legal counsel (including counsel for any Loan Party), independent accountants, and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any
Note as the holder thereof for all purposes hereof unless and until the Administrative Agent receives and accepts an Assignment and Assumption executed in accordance with Section 8.07. As to any matters not expressly provided for by this Agreement,
the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the
Required Lenders or, to the extent any action requires the consent of all Lenders as specifically provided in Section 8.01, upon the instructions of all Lenders, and such instructions shall be binding on all of the Lender Parties; provided,
however, that the Administrative Agent shall not be required to take any action that exposes the Administrative Agent to personal liability or that is contrary to any Loan Document or applicable Requirements of Law or unless it shall first be
indemnified to its satisfaction by the Lender Parties against any and all liability and expense which may be incurred by it by reason of taking any such action. 
  

SECTION 7.03. Defaults. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or Event of
Default unless the Administrative Agent has received written notice from a Lender Party or the Borrower specifying such Default or Event of Default and stating that such notice is a “Notice of Default”. In the event that the Administrative
Agent receives such a notice of the occurrence of a Default or Event of Default, the Administrative Agent shall give prompt notice thereof to the Lender Parties. The Administrative Agent shall (subject to Section 7.02) take such action with respect
to such Default or Event of Default as shall reasonably be directed by the Required Lenders or, to the extent any action requires the consent of all Lenders as specifically provided in Section 8.01, then as directed by all Lenders; provided
that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interest of the Lender Parties. 
  
 SECTION 7.04. CSFB and Affiliates. With respect to its Commitments, the Advances made by it and the Note or Notes issued to it, CSFB (and any successor acting as the Administrative Agent) in its capacity as a
Lender Party hereunder shall have the same rights and powers under the Loan Documents as any other Lender Party and may exercise the same as though it were not acting as the Administrative Agent; and the term “Lender Party” or “Lender
Parties” shall, unless otherwise expressly indicated, include CSFB in its individual capacity. CSFB (and any successor acting as the Administrative Agent), and its affiliates may (without having to account therefor to any Lender Party) accept
deposits from, lend money to, make investments in, provide services to, and generally engage in any kind of lending, trust, or other business with any Loan Party or any of its Subsidiaries or Affiliates as if it were not acting as an Agent, and CSFB
(and any successor acting as the Administrative Agent), and its affiliates may accept fees and other consideration from any Loan Party or any of its Subsidiaries or Affiliates, or any Person that may do business with or own securities of any Loan
Party or any such Subsidiary or Affiliate, for services in connection with this Agreement or otherwise without having to account for the same to the Lender Parties. 
  
 SECTION 7.05. Indemnification. 
  
 (a) The Lenders severally agree to indemnify the Administrative Agent (to the extent not promptly reimbursed
under Section 8.04, but without limiting the obligations of the Borrower under such Section) ratably in accordance with their respective Commitments, for any and all 

  

 88 








 
liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including attorneys’ fees), or disbursements of any
kind and nature whatsoever that may be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of any Loan Document or the transactions contemplated thereby or any action taken or omitted by the
Administrative Agent under any Loan Document (collectively, the “Indemnified Costs”); provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful
misconduct of the Person to be indemnified. In the case of any claim, investigation, litigation or proceeding for which indemnity under this Section 7.05(a) applies, such indemnity shall apply whether or not such claim, investigation, litigation or
proceeding is brought by the Administrative Agent, any of the other Agents, any of the Lender Parties or a third party. Without limitation of the foregoing, each Lender severally agrees to reimburse the Administrative Agent promptly upon demand for
its ratable share of any costs or expenses payable by the Borrower under Section 8.04, to the extent that the Administrative Agent is not promptly reimbursed for such costs and expenses (including, without limitation, fees and expenses of counsel)
by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by any Lender Party or any other Person.
The failure of any Lender Party to reimburse the Administrative Agent promptly upon demand for its ratable share of any amount required to be paid by the Lender Party to the Administrative Agent as provided herein shall not relieve any other Lender
Party of its obligation hereunder to reimburse the Administrative Agent for its ratable share of such amount, but no Lender Party shall be responsible for the failure of any other Lender Party to reimburse the Administrative Agent for such other
Lender Party’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender Party hereunder, the agreement and obligations of each Lender contained in this Section 7.05(a) shall survive the payment in
full of principal, interest and all other amounts payable hereunder and under the other Loan Documents. 
  
 (b) The Revolving Credit Lenders severally agree to indemnify the Issuing Bank (to the extent not promptly reimbursed under Section 8.04,
but without limiting the obligations of the Borrower under such Section) for such Revolving Credit Lender’s Pro Rata Share of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Issuing Bank in any way relating to or arising out of the Loan Documents or the transactions contemplated thereby or any action taken or
omitted by the Issuing Bank under the Loan Documents; provided, however, that no Revolving Credit Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the Issuing Bank’s gross negligence or willful misconduct. In the case of any claim, investigation, litigation or proceeding for which indemnity under this Section 7.05(b) applies, such indemnity shall
apply whether or not such claim, investigation, litigation or proceeding is brought by the Issuing Bank, any of the other Lender Parties or a third party. Without limitation of the foregoing, each Revolving Credit Lender severally agrees to
reimburse the Issuing Bank promptly upon demand for its Pro Rata Share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Borrower under Section 8.04, to the extent that the Issuing Bank is not
promptly reimbursed for such costs and expenses by the Borrower. The failure of any Revolving Credit Lender to reimburse the Issuing Bank promptly upon demand for its Pro Rata Share of any amount required to be paid by the Revolving Credit Lenders
to the Issuing Bank as provided herein shall not relieve any other Revolving Credit Lender of its obligation hereunder to reimburse the Issuing Bank for its Pro Rata Share of such amount, but no Revolving Credit Lender shall be responsible for the
failure of any other Revolving Credit Lender to reimburse the Issuing Bank for such other Revolving Credit Lender’s Pro Rata Share of such amount. Without prejudice to the survival of 

  

 89 








 
any other agreement of any Revolving Credit Lender hereunder, the agreement and obligations of each Revolving Credit Lender contained in this Section 7.05(b)
shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents. 
  
 SECTION 7.06. Non-Reliance on Agent and Other Lender Parties. Each Lender Party agrees that it has, independently and without reliance on any Agent
or any other Lender Party, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Loan Parties and their Subsidiaries and decision to enter into this Agreement and that it will, independently
and without reliance upon any Agent or any other Lender Party, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under the Loan
Documents. Except for notices, reports, and other documents and information expressly required to be furnished to the Lender Parties by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide
any Lender Party with any credit or other information concerning the affairs, financial condition, or business of any Loan Party or any of its Subsidiaries or Affiliates that may come into the possession of the Administrative Agent or any of its
affiliates. 
  
 SECTION 7.07. Resignation of Administrative
Agent. The Administrative Agent may resign at any time by giving notice thereof to the Lender Parties and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no
successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may,
on behalf of the Lender Parties, appoint a successor Administrative Agent which shall be a commercial bank organized under the laws of the United States of America or of any state thereof and having combined capital and surplus of at least
$100,000,000. If within 30 days after written notice is given of the retiring Administrative Agent’s resignation under this Section 7.07 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then
on such 30th day (a) the retiring Administrative Agent’s resignation shall become effective, (b) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (c) the Required
Lenders shall thereafter perform all duties and obligations of the retiring Administrative Agent under the Loan Documents until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above in this Section
7.07. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor and upon the execution and filing or recording of such financing statements, or amendments thereto, and such other instruments or notices, as may be
necessary or desirable, or as the Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Collateral Documents, such successor Administrative Agent shall thereupon succeed to and
become vested with all the rights, powers, discretion, privileges, and duties of the retiring Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under the Loan Documents. After any retiring Agent’s
resignation hereunder as Administrative Agent, the provisions of this Article VII 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 Administrative Agent. 
  
 SECTION 7.08. Release of Collateral. Upon the payment of all Notes and
all other amounts payable under the Loan Documents, the termination of all Letters of Credit and the termination of all commitments of the Lender Parties hereunder, the Lender Parties hereby agree that all Collateral is released from the security
interest granted under the respective Collateral Documents, and upon (i) the sale, lease, transfer or other disposition of any item of Collateral of any Loan Party, (ii) the issuance or sale pursuant to Section 5.02(m)(iii) of any Equity Interests
causing a Subsidiary of the Borrower to cease to be wholly-owned by the Borrower or any of its Subsidiaries, in each case in accordance with the terms 

  

 90 








 
of the Loan Documents, the Lender Parties hereby agree that such item of Collateral in the case of clause (i), or all Collateral owned by such Subsidiary in
the case of clause (ii), shall be released from the security interest granted under the respective Collateral Documents. In connection therewith, the Lender Parties hereby irrevocably authorize the Administrative Agent to release any such
Collateral. The Administrative Agent will, at the Borrower’s expense, execute and deliver to the respective Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the security
interest granted under the Collateral Documents. 
  
 SECTION 7.09.
Release of Guarantor. Upon the sale of outstanding shares of capital stock and other equity, ownership and profit interests in any Guarantor in a transaction which is permitted under Section 5.02(e) and, if applicable, 5.02(m)(iii), then upon
request by the Borrower, the Administrative Agent, on behalf of each Lender Party, shall confirm in writing that the liability of such Guarantor under the Subsidiary Guarantee is released and discharged effective when such transaction is consummated
and all requirements hereunder in connection therewith are satisfied, including with respect to the application of the proceeds of such sale. Such confirmation from the Administrative Agent (a) shall establish conclusively that the liability of such
Guarantor under the Subsidiary Guarantee is released and discharged and (b) may be relied on, without further inquiry, by the purchaser in such transaction and each of its transferees. Each Lender Party hereby irrevocably authorizes the
Administrative Agent to release any Guarantor from time to time to the extent provided for herein and to execute any document reasonably required in connection therewith. 
  
 SECTION 7.10. Actions in Respect of Intercreditor Agreement. The Lenders and the Issuing Banks hereby authorize the
Administrative Agent, in its capacity as Administrative Agent on behalf of the Lenders and the Issuing Banks, to enter into the Intercreditor Agreement and hereby consent to the Administrative Agent acting as Collateral Agent under the Intercreditor
Agreement.

 SECTION 8.03. No Waiver; Remedies. No failure on the part of any Lender Party or any Agent to exercise, and no delay in exercising, any right,
power or privilege hereunder or under any Note or any other Loan Document shall operate as a waiver thereof or consent thereto; nor shall any single or partial exercise of any such right, power or privilege preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The remedies herein provided are cumulative and not exclusive of any remedies provided by applicable law. 
  
 SECTION 8.04. Costs and Expenses. 
  
 (a) The Borrower agrees to pay on demand (i) all costs and expenses of each Agent in connection with the
syndication, preparation, execution, delivery, administration, modification and amendment of, or any consent or waiver under, the Loan Documents and the other documents to be delivered thereunder (including, without limitation, (A) all due
diligence, collateral review, syndication, transportation, computer, duplication, appraisal, audit, insurance, consultant, search, filing and recording fees and expenses and (B) the reasonable fees and expenses of counsel for the Administrative
Agent (including the cost of internal counsel) with respect thereto, with respect to advising such Agent as to its rights and responsibilities, or the perfection, protection or preservation of rights or interests, under the Loan Documents), and (ii)
all costs and expenses of each Agent and each Lender Party in connection with the enforcement of the Loan Documents and the other documents to be delivered thereunder, whether in any action, suit or litigation, or any bankruptcy, insolvency or other
similar proceeding affecting creditors’ rights generally (including, without limitation, the reasonable fees and expenses of counsel (including the cost of internal counsel) for the Administrative Agent and each Lender Party with respect
thereto). 
  

 93 








 (b) The Borrower agrees to indemnify, defend and save and hold harmless each Agent, each
Lender Party and each of their affiliates and their respective affiliates, officers, directors, trustees, employees, agents and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all
claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection
with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (i) the Transaction (or any aspect thereof), Facilities, the actual or proposed
use of the proceeds of the Advances or the Letters of Credit, the Loan Documents, or any of the transactions contemplated thereby; (ii) any acquisition or proposed acquisition by the Borrower or any of its Subsidiaries or Affiliates of all or any
portion of the Equity Interests in or Debt securities or substantially all of the property and assets of any other Person; or (iii) the actual or alleged presence of Hazardous Materials on any property of any Loan Party or any of its Subsidiaries or
any Environmental Action relating in any way to any Loan Party or any of its Subsidiaries, except to the extent such claim, damage, loss, liability or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have
resulted from such Indemnified Party’s gross negligence or willful misconduct or have arisen after such Loan Party or Subsidiary is dispossessed of or relinquishes its interest in such property. In the case of an investigation, litigation or
other proceeding to which the indemnity in this Section 8.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by any Loan Party, its directors, shareholders or creditors or an
Indemnified Party or any other Person, whether or not any Indemnified Party is otherwise a party thereto and whether or not the Transaction or any of the other transactions contemplated hereby is consummated. If and to the extent that the indemnity
in this subsection (b) is unenforceable for any reason other than by operation of the last clause of the first sentence of this subsection 8.04(b), the Borrower hereby agrees to make to each applicable Indemnified Party the maximum contribution to
the payment of the claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) for which the indemnity in this subsection (b) has been determined to be unenforceable that is permitted
under applicable law. The Borrower also agrees not to assert any claim against any Agent, any Lender Party or any of their respective affiliates, officers, directors, trustees, employees, agents and advisors, on any theory of liability, for special,
indirect, consequential or punitive damages arising out of or otherwise relating to the Transaction (or any aspect thereof) Facilities, the actual or proposed use of the proceeds of the Advances or the Letters of Credit, the Loan Documents, or any
of the other transactions contemplated hereby. 
  
 (c) If any payment of principal of, or Conversion of, any Eurodollar Rate Advance is made by the Borrower to or for the account of a Lender Party other than on the last day of the Interest Period for such Advance, as a result of a payment
or Conversion pursuant to Section 2.06, 2.09(b)(i) or 2.10(d), acceleration of the maturity of the Notes pursuant to Section 6.01 or for any other reason, or by an Eligible Assignee to a Lender Party other than on the last day of the Interest Period
for such Advance upon an assignment of rights and obligations under this Agreement pursuant to Section 8.07 as a result of a demand by the Borrower pursuant to Section 8.07(a), or if the Borrower fails to make any payment or prepayment of an Advance
for which a notice of prepayment has been given or that is otherwise required to be made, whether pursuant to Section 2.04, 2.06 or 6.01 or otherwise, the Borrower shall, upon demand by such Lender Party (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such Lender Party any amounts required to compensate such Lender Party for any additional losses, costs or expenses that it may reasonably incur as a result of such payment or
Conversion or such failure to pay or prepay, as the case may be, including, without limitation, any 

  

 94 








 
loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender Party to fund or maintain such
Advance. 
  
 (d) If any Loan Party fails to pay
when due, after the expiration of any grace period, if applicable, any costs, expenses or other amounts payable by it under any Loan Document, including, without limitation, fees and expenses of counsel and indemnification payments, such amount may
be paid on behalf of such Loan Party by the Administrative Agent or any Lender Party, in its sole discretion. 
  
 (e) Without prejudice to the survival of any other agreement of any Loan Party hereunder or under any other Loan Document, the agreements
and obligations of the Borrower contained in Sections 2.10 and 2.13 and this Section 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under any of the other Loan Documents. 
  
 SECTION 8.05. Right of Set-off. Upon (a) the occurrence and during the
continuance of any Event of Default and (b) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Notes due and payable pursuant to the provisions of Section 6.01,
each Agent and each Lender Party and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and otherwise 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 Agent, such Lender Party or such Affiliate to or for the credit or the account of the Borrower against any and all of the Obligations of the Borrower now
or hereafter existing under the Loan Documents, irrespective of whether such Agent or such Lender Party shall have made any demand under this Agreement or such Note or Notes and although such Obligations may be unmatured. Each Agent and each Lender
Party agrees promptly to notify the Borrower after any such set-off and application; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Agent and
each Lender Party and their respective Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Agent, such Lender Party and their respective Affiliates may have.

  
 SECTION 8.06. Successors and Assigns. (a) The
provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of each Lender Party and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with Section 8.07(a), (ii) by way
of participation in accordance with Section 8.07(e), or (iii) by way of pledge or assignment of a security interest subject to the restrictions of Section 8.07(f) (and any other attempted assignment or transfer by any party hereto shall be null and
void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in Section 8.07(e)
and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lender Parties) any legal or equitable right, remedy or claim under or by reason of this Agreement. 
  
 SECTION 8.07. Assignments and Participations. 
  
 (a) (i) Any Lender may, and (ii) so long as no Default under
Section 6.01(a) or 6.01(f) or Event of Default has occurred and is continuing, if demanded by the Borrower (following (x) a demand by such Lender for the payment of additional compensation pursuant to Section 2.10(a), 2.10(b) or 2.13 or (y) an
assertion by such Lender pursuant to Section 2.10(c) or 

  

 95 








 
2.10(d) that it is impractical or unlawful for such Lender to make Eurodollar Rate Advances), upon at least five Business Days’ notice to such Lender
and the Administrative Agent, each of the Lenders will, at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment or
Commitments, the Advances owing to it, the Note or Notes held by it and its participation in reimbursement obligations of the Borrower in respect of Letters of Credit); provided that: 
  
 (A) except in the case of an assignment of the entire
remaining amount of the assigning Lender’s Commitment or Commitments, the Advances owing to it, the Note or Notes held by it, its participation in reimbursement obligations of the Borrower in respect of Letters of Credit or in the case of an
assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Advances outstanding thereunder) or, if the applicable Commitment is not then in
effect, the principal outstanding balance of the Advance of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if
“Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $2,500,000, in the case of any assignment in respect of the Revolving Credit Facility, or $1,000,000, in the case of any assignment in
respect of the Term Loan Facility; 
  
 (B) each
assignment shall require the consent of the Borrower (not to be unreasonably withheld or delayed), except for an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or, if an Event of Default has occurred and is continuing, or if
such assignment is made in connection with the syndication of the Revolving Credit Commitments or any Term Facility, any other assignee; 
  
 (C) each assignment will require the consent of the Administrative Agent (not to be unreasonably withheld or delayed); 
  
 (D) each partial assignment shall be made as an assignment
of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Advance or the Commitment assigned, except that this clause (B) shall not prohibit any Lender from assigning all or a portion
of its rights and obligations among separate Facilities on a non-pro rata basis; 
  
 (E) any assignment of a Revolving Credit Commitment must be approved by the Administrative Agent and the Issuing Bank unless the Person
that is the proposed assignee is itself a Lender with a Revolving Credit Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee); 
  
 (F) the parties to each assignment shall (x) electronically execute and deliver to the Administrative Agent
an Assignment and Assumption via an electronic settlement system acceptable to the Administrative Agent (which initially shall be Clearpar, LLC), together with any Note or Notes subject to such 

  

 96 








 
assignment, or (y) manually execute and deliver to the Administrative Agent an Assignment and Assumption, together with any Note or Notes subject to such
assignment and, except in the case of an assignment by any of the Lenders to an Affiliate or an Approved Fund of such Lender, a processing and recordation fee of $3,500 (and in the case of simultaneous assignments on the same day by or to more than
one fund managed or advised by the same investment advisor (which funds are not then Lenders hereunder), only a single $3,500 processing and recordation fee shall be payable for all such assignments), at the discretion of the Administrative Agent,
and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; 
  
 (G) the Swing Line Bank may not assign or otherwise transfer to any other Person any of its rights or obligations under its Swing Line
Commitment. 
  
 (H) each such assignment made as
a result of a demand by the Borrower pursuant to this Section 8.07(a)(ii) shall be arranged by the Borrower after consultation with the Administrative Agent and shall be either an assignment of all of the rights and obligations of the assigning
Lender under this Agreement or an assignment of a portion of such rights and obligations made concurrently with another such assignment or other such assignments that together cover all of the rights and obligations of the assigning Lender under
this Agreement. 
  
 (b) Subject to acceptance and
recording thereof by the Administrative Agent pursuant to Section 8.07(c), from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the
interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender or the Issuing Bank under this Agreement, and the assigning Lender or Issuing Bank thereunder shall, to the extent of the interest assigned by such
Assignment and Assumption, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s or Issuing Bank’s rights and obligations
under this Agreement, such Lender or Issuing Bank shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.10, 2.13 and 8.04 (and other similar provisions of the other Loan Documents to survive the payment in
full of the Obligations of the Loan Parties under or in respect of the Loan Documents) with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with this Section 8.07(b). 
  
 (c) The Administrative Agent, acting solely for this purpose
as an agent of the Borrower, shall maintain at its office as set forth in Section 8.02, a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lender Parties, and the Commitments
of, and principal amounts of the Advances owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and
the Lender Parties may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender Party hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Administrative Agent shall (i)
upon the request by the Borrower or any Lender Party, provide a copy of the Register to the Borrower or such Lender Party, and (ii) upon its receipt of an Assignment and Assumption executed by an assigning Lender Party or Issuing Bank and an
assignee, together with any Note or Notes subject to such assignment, if such Assignment and Assumption has been completed and is in substantially the form of Exhibit C hereto, (x) accept such Assignment and Assumption, and (y) record the
information contained therein in the 

  

 97 








 
Register. In the case of any assignment by a Lender Party, the Borrower shall, at its own expense, and upon request by the Administrative Agent or any
assignee, execute and deliver to the Administrative Agent in exchange for the surrendered Note or Notes a new Note or Notes from the Borrower payable to or to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it
under each Facility pursuant to such assignment and Assumption and, if the assigning Lender Party has retained a Commitment under such Facility, a new Note or Notes from the Borrower payable to or to the order of the assigning Lender Party in an
amount equal to the Commitment retained by it under such Facility. Each of the new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date
of such Assignment and Assumption and shall otherwise be in substantially the form of Exhibit A-1, Exhibit A-2 or Exhibit A-3 hereto, as appropriate. 
  
 (d) Any Lender Party may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations
to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender Party’s rights and/or obligations under this
Agreement (including all or a portion of its Commitment or Commitments, the Advances owing to it, the Note or Notes, if any, held by it and its participation, if any, in reimbursement obligations of the Borrower in respect of Letters of Credit);
provided that: 
  
 (i) such Lender
Party’s obligations under this Agreement shall remain unchanged, 
  
 (ii) such Lender Party shall remain solely responsible to the other parties hereto for the performance of such obligations and 
  

(iii) the Borrower, the Administrative Agent and the other Lender Parties shall continue to deal solely and directly with such Lender
Party in connection with such Lender Party’s rights and obligations under this Agreement. 
  
 Any agreement or instrument pursuant to which a Lender Party sells such a participation shall provide that such Lender Party shall retain
the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender Party will not, without the consent of
the Participant, agree to any amendment, modification or waiver described in Section 8.01(a) or (b) that affects such Participant. Subject to Section 8.07(e), the Borrower agrees that each Participant shall be entitled to the benefits of Sections
2.10, 2.13 and 8.04 to the same extent as if it were a Lender Party and had acquired its interest by assignment pursuant to Section 8.07(a). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as
though it were a Lender Party. 
  
 (e) A
Participant shall not be entitled to receive any greater payment under Sections 2.10, 2.13 and 8.04 than the applicable Lender Party would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of
the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a foreign lender party if it were a Lender Party shall not be entitled to the benefits of Section 2.13 unless the Borrower is
notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.13 as though it were a Lender Party. 
  

 98 








 (f) Any Lender Party may at any time pledge or assign a security interest in all or any
portion of its rights under this Agreement to secure obligations of such Lender Party, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall
release such Lender Party from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender Party as a party hereto. In the case of any Lender that is a fund that invests in bank loans, such Lender may, without the
consent of the Borrower or Administrative Agent, assign or pledge all or any portion of its rights under this Agreement, including the Loans and Notes or any other instrument evidencing its rights as a Lender under this Agreement, to any holder of,
trustee for, or any other representative of holders of, obligations owed or securities issued, by such fund, as security for such obligations or securities; provided that any foreclosure or similar action by such trustee or representative
shall be subject to the provisions of this Section 8.07 concerning assignments. 
  
 (g) Notwithstanding anything to the contrary contained herein, any Lender Party (a “Granting Lender”) may grant to
a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Advance that such
Granting Lender would otherwise be obligated to make pursuant to this Agreement, provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Advance, and (ii) if an SPC elects not to exercise such option or otherwise
fails to make all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same
extent, and as if, such Advance were made by such Granting Lender. Each party hereto hereby agrees that (i) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender Party would be liable, (ii) no
SPC shall be entitled to the benefits of Sections 2.10 and 2.13 (or any other increased costs protection provision) and (iii) the Granting Lender shall for all purposes, including, without limitation, the approval of any amendment or waiver of any
provision of any Loan Document, remain the Lender Party of record hereunder. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year
and one day after the payment in full of all outstanding commercial paper or other senior Debt of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement,
insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without prior consent of, the Borrower and the
Administrative Agent and without paying any processing fee therefor, assign all or any portion of its interest in any Advance to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of
Advances to any rating agency, commercial paper dealer or provider of any surety or guarantee or credit or liquidity enhancement to such SPC. This subsection (g) may not be amended without the prior written consent of each Granting Lender, all or
any part of whose Advances are being funded by the SPC at the time of such amendment. 
  
 (h) In the event that the Borrower shall request that the Lender Parties enter into any amendment, modification, consent or waiver with
respect to this Agreement or any other Loan Document, and any Lender Party elects not to enter into such amendment, modification, consent or waiver (each such Lender Party being a “Dissenting Lender”), then the Borrower shall
have the right upon 10 days’ written notice to the Administrative Agent and such Dissenting Lender, to require each such Dissenting Lender to assign 100% of the rights and obligations of the Dissenting Lender at par to any Lender or any other
financial institution which satisfies the requirements of Section 8.07(a) and has been consented to by the Administrative Agent, the 

  

 99 








 
Swing Line Lender and in the case of any assignment of a Revolving Credit Commitment each Issuing Bank (which consents in the case of the Administrative
Agent and the Swing Line Lender shall not be unreasonably withheld or delayed). Each such assignment shall be made pursuant to an Assignment and Assumption and shall comply with the other terms of this Section 8.07. The Borrower shall pay to such
Dissenting Lender, concurrently with the effectiveness of such assignment, any amounts payable under this Agreement that would have been payable if the Borrower had voluntarily prepaid such Advances. The Dissenting Lender shall not be required to
pay any fee relating to such assignment. 
  
 SECTION 8.08.
Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together
shall constitute one and the same agreement. Delivery by telecopier of an executed counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement. 
  
 SECTION 8.09. No Liability of the Issuing Bank. The Borrower assumes
all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Bank nor any of its officers or directors shall be liable or responsible for: (a) the
use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) 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; (c) payment by the Issuing Bank against presentation of documents that do not comply with the terms of a Letter of Credit, including failure of any documents to bear any
reference or adequate reference to the Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit, except that the Borrower shall have a claim against the Issuing Bank, and the Issuing
Bank shall be liable to the Borrower, to the extent of any direct, but not consequential, damages suffered by the Borrower that the Borrower proves were caused by (i) the Issuing Bank’s willful misconduct or gross negligence, or failure to
conform with the standards specified in Section 5-108 of the UCC, as determined in a final, non-appealable judgment by a court of competent jurisdiction in determining whether documents presented under any Letter of Credit comply with the terms of
the Letter of Credit or (ii) the Issuing Bank’s willful failure to make lawful payment under a Letter of Credit after the presentation to it of a draft and certificates strictly complying with the terms and conditions of the Letter of Credit.
In furtherance and not in limitation of the foregoing, but subject to Section 5-109(a) of the UCC, the Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any
notice or information to the contrary. 
  
 SECTION 8.10.
Confidentiality. Neither any Agent nor any Lender Party shall disclose any Confidential Information to any Person without the consent of the Borrower, other than (a) to such Agent’s or such Lender Party’s Affiliates and their
officers, directors, employees, agents and advisors, to other Lender Parties and to actual or prospective Eligible Assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process,
(c) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Lender Party, (d) to any
rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Loan Parties received by it from such Lender
Party in accordance with such rating agency’s internal procedures generally applicable to information of the same type, (e) in connection with any litigation or proceeding to which such Agent or such Lender Party or any of its Affiliates may be
a party, (f) in connection with the exercise of any remedy under this Agreement or any other Loan Document, or (g) to any direct or indirect contractual counterparty in swap agreements or such contractual 

  

 100 








 
counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be
bound by the provisions of this Section 8.10). Notwithstanding anything herein to the contrary, each Loan Party, each Lender Party and the Administrative Agent and each of their respective officers, directors, employees, accountants, attorneys and
other advisors, agents and representatives, may disclose to any and all persons, without limitation of any kind, any information with respect to the United States tax treatment and tax structure of the transactions contemplated by the Loan Documents
and all materials of any kind (including opinions or other tax analyses) that are provided in respect to the respective Loan Party, Lender Party or the Administrative Agent, as the case may be, relating to such United States tax treatment and tax
structure. 
  
 SECTION 8.11. Execution in Counterparts.
This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same
agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement. 
  
 SECTION 8.12. Governing Law, Jurisdiction, Etc. 
  
 (a) This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the
State of New York (without reference to conflict of laws provisions). 
  
 (b) Each of the parties hereto hereby irrevocably and unconditionally submits, for itself and its property and assets, to the nonexclusive jurisdiction of any New York State court or any federal court of the United
States of America sitting in New York City, New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents to which it is a party, or for recognition or
enforcement of any judgment in respect thereof, 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 any such New York State court or,
to the fullest extent permitted under applicable law, in any such federal court. Each of the parties hereto hereby irrevocably consents to the service of copies of any summons and complaint and any other process which may be served in any such
action or proceeding by certified mail, return receipt requested, or by delivering a copy of such process to such party, at its address specified in Section 8.02, or by any other method permitted under applicable law. Each of the parties hereto
hereby 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 applicable law. Nothing in this Agreement shall affect any
right that any of the parties hereto may otherwise have to bring any action or proceeding relating to this Agreement or any of the other Loan Documents in the courts of any jurisdiction. 
  
 (c) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally
and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents to which it is a party in any New York
State or federal court. 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 8.13. Designation as Designated Senior Debt. This Agreement,
the Subsidiary Guarantee, the Loan Documents and all monetary obligations hereunder or thereunder are hereby expressly designated as “Designated Senior Indebtedness” as that term (or any comparable term) is defined in the Subordinated
Notes Documents. 
  

 101 








 SECTION 8.14. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENTS AND THE LENDER PARTIES
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY OF THE LOAN DOCUMENTS, THE ADVANCES, THE LETTERS OF CREDIT OR THE ACTIONS OF ANY
AGENT OR ANY LENDER PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF. 
  
 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the
date first above written.

 Schedule 4.01(s) 
  
 To The Credit Agreement 
  
 Exceptions to Medicare/ Medicaid Participation 
  
 Each time Borrower or one of its Subsidiaries develops a new facility (a “De Novo”), it is operated for a limited period of time prior to obtaining its Medicare
certification and provider number and its Medicaid provider number. Once the De Novo passes its initial survey from Medicare it is approved for billing as of the date of the survey. However, Borrower or one of its Subsidiaries will not be able to
remit bills to Government Reimbursement Programs until it is actually issued a provider number, which could be several months after the initial survey. 
  
 Each time Borrower or one of its Subsidiaries acquires a new facility (an “Acquisition”), similar delays may result. While a facility remains qualified to
participate in the Government Reimbursement Programs after an Acquisition, Borrower or one of its Subsidiaries cannot bill the Government Reimbursement Programs until it receives a provider number in its own name. 
  
 The listing below reflects facilities where Borrower or one of its Subsidiaries is awaiting
i) an initial Medicare certification and provider number with which to bill a Medicare intermediary, ii) an initial Medicaid provider number with which to bill or iii) to have a Medicare or Medicaid provider number issued in the name of Borrower or
one of its Subsidiaries after acquiring a facility. These delays in Medicare certifications and in issuing provider numbers are part of Borrower’s ordinary course operations. As a result, this list is subject to change from time to time.

banks party thereto as issuing banks, Credit Suisse First Boston (“CSFB”), as swing line bank and administrative agent, CSFB and Banc of America Securities LLC, as the joint book running managers and joint lead arranger in respect of the

 Ladies and Gentlemen: 
  
 I am the General Counsel of DaVita, Inc., a Delaware corporation (“Borrower”). This opinion is rendered to you in
compliance with 3.01(a) of the Credit Agreement. Capitalized terms used herein without definition have the same meanings as in the Credit Agreement. 
  
 In my capacity as such counsel, I have examined originals, or copies identified to my satisfaction as being true copies, of such records, documents or
other instruments as in my judgment are necessary or appropriate to enable me to render the opinions expressed below. These records, documents and instruments included the following:

 (a) The certificate or articles of incorporation or other organizational documents, as applicable, of each Loan Party, as amended to date;

  
 (b) The bylaws, partnership agreement or
operating agreement, as applicable, of each Loan Party, as amended to date; 
  
 (c) All records of proceedings and actions of the board of directors, partners or members, as applicable, of each Loan Party relating to the Loan Documents and the transactions contemplated thereby; 
  
 (d) The Credit Agreement; 
  
 (e) The Term B Notes; 
  
 (f) The Subsidiary Guarantee; 
  
 (g) The Security Agreement; and 
  
 (h) The Intellectual Property Security Agreement by the Loan
Parties in favor of the Collateral Agent (as defined in the Security Agreement) dated the date hereof (the “Intellectual Property Security Agreement”). 
  
 I have been furnished with, and with the Lender Parties’ consent have relied upon, certificates of officers of each
Loan Party with respect to certain factual matters, copies of which have been delivered to the Lender Parties. In addition, I have obtained and relied upon such certificates and assurances from public officials as I have deemed necessary, copies of
which have been delivered to the Lender Parties. As to any facts material to the opinions expressed herein that were not independently established or verified, I have relied upon the representations and warranties of the Loan Parties made in the
Loan Documents and upon statements and representations of officers and other representatives of the Loan Parties. In all such examinations, I have assumed the genuineness of all signatures (other than the signatures of any Loan Party in connection
with any Loan Document) on original and certified documents, and the conformity to original or certified documents of all documents submitted to me as conformed or photo-static copies. 
  
 To the extent that the obligations of the Borrower and each other Loan Party may be dependent upon such matters, I have
assumed for purposes of this opinion, other than with respect to the Borrower and each other Loan Party, that each additional party to the agreements and contracts referred to herein is duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization; that each such other party has the requisite corporate or other organizational power and authority to perform its obligations under such agreements and contracts, as applicable; and that such agreements and
contracts have been duly authorized, executed and delivered by, and each of them constitutes the legally valid and binding obligation of, such other parties, as applicable, enforceable against such other parties in accordance with their respective
terms. Except as expressly covered in this opinion, I am not expressing any opinion as to the effect of compliance by any Lender Party with any

state or Federal laws or regulations applicable to the transactions because of the nature of any of its businesses. 
  
 I have not made or undertaken to make any investigation of the state of title
to any of the Collateral (as defined in the Security Agreement) and I express no opinion concerning title to any property included in the Collateral. You have advised me that in rendering the opinions set forth below I may assume that (i) with
respect to the Security Agreement and the Intellectual Property Security Agreement, Borrower and each other Loan Party has “rights” within the meaning of Section 9203(b)(2) of the Uniform Commercial Code of the State of California (the
“California UCC”) in the Collateral, consistent with the purposes of the Security Agreement; and (ii) each Secured Party under the Security Agreement and the Intellectual Property Security Agreement will act in good faith and will seek to
enforce its rights and remedies under the Loan Documents in a commercially reasonable manner. 
  
 I have investigated such questions of law for the purpose of rendering this opinion as I have deemed necessary. I am an attorney duly admitted and qualified to practice only in the State of California, and I am
opining herein only as to the effect on the subject transaction of the laws of the State of California, the Delaware General Corporation Law and United States Federal law. I am not opining on, and I assume no responsibility as to the applicability
to or the effect on any of the matters covered herein of, the laws of any other jurisdiction. In addition, I do not express any opinion as to any law applicable to the environment, real estate, taxes, “bulk sales”, securities, “blue
sky” or antifraud matters. I note that the Credit Agreement provides that it shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York, and that the other Loan Documents contain similar provisions
and that I am not opining herein under the laws of the State of New York. With your permission, I am delivering the opinions herein assuming that the laws of the State of New York that relate to the Credit 
  
 Agreement and the other Loan Documents are identical in all material respects
to the internal laws of the State of California (without giving effect to conflict of law principles). 
  
 On the basis of the foregoing, and in reliance thereon, and subject to the limitations, qualifications and exceptions set forth below, I am of the opinion
that: 
  
 1. The Borrower is a corporation duly
incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation and has all requisite corporate power and authority to own and operate its properties and to carry on its business as now conducted. The Borrower
is duly qualified to do business as a foreign corporation, and is in good standing, in the State of California. 
  
 2. Each of the Guarantors which is a Domestic Subsidiary of Borrower, is an entity duly formed, validly existing and, to the extent such
concept is applicable, in good standing under the laws of its jurisdiction of organization and has all requisite corporate, partnership or limited liability company power and authority, as applicable, to own and operate its properties and to carry
on its business as now conducted.

 3. Each of the Loan Parties other than the Borrower is duly qualified to do business
in the foreign jurisdictions set forth opposite its name in Exhibit A attached hereto, other than Total Renal Support Services, Inc. in the State of Missouri. 
  
 4. The execution, delivery and performance by each Loan Party of each Loan Document to which it is or is to
be a party are within such Loan Party’s corporate, partnership or limited liability company powers, as applicable, have been duly authorized by all necessary corporate, partnership or limited liability company action, as applicable, and do not
(i) contravene such Loan Party’s Constitutive Documents, (ii) violate any present Federal, Delaware corporation or California statute, rule or regulation binding on such Loan Party, (iii) conflict with or result in the breach of, or constitute
a default or require any payment to be made under, any contract, loan agreement, indenture, mortgage, deed of trust, lease or other instrument binding on or affecting any Loan Party or any of its properties or (iv) except for the Liens created under
the Loan Documents, result in or require the creation or imposition of any Lien upon or with respect to any of the properties of any Loan Party. 
  
 5. The Loan Documents have been duly executed and delivered by and constitute the legally valid and binding obligations of each Loan
Party, enforceable against such Loan Party in accordance with their respective terms. 
  
 6. No consents or approvals of, and no other authorization or approval or other action by, and no notice to or filing with, any Federal,
Delaware or California Governmental Authority or any other third party is required for (i) the due execution, delivery, recordation, filing or performance by any Loan Party of any Loan Document to which it is or is to be a party, or for the
consummation of the Transaction, (ii) the grant by any Loan Party of the Liens granted by it pursuant to the Collateral Documents, (iii) the perfection or maintenance of the Liens created under the Collateral Documents on such of the Collateral
located in the United States in which a Lien may be perfected by the filing of financing statements, the recordation of security agreements with the U.S. Patent and Trademark Office or the U.S. Copyright Office or the delivery of Collateral or (iv)
the exercise by any Secured Party of its rights under the Loan Documents or the remedies in respect of the Collateral pursuant to the Collateral Documents, except for (A) the authorizations, approvals and actions on Schedule 4.01(d) to the Credit
Agreement, all of which have been duly obtained and are in full force and effect (except as may otherwise be noted in such schedule), (B) filings, notices, recordings and other similar actions necessary for the creation or perfection of the Liens
and security interests contemplated by the Loan Documents and (C) the actions required by laws generally with respect to the exercise by secured creditors of their rights and remedies. 
  
 7. Set forth on Schedule 4.01(b) to the Credit Agreement is a complete list of all Subsidiaries of the
Borrower. All of the outstanding Equity Interests of each Subsidiary (in the case of Subsidiaries that are corporations) have been validly issued, are fully paid and non-assessable.

 8. Except as described on Schedule 4.01(f) of the Credit Agreement or disclosed prior
to the Closing Date in the Borrower’s filings made with the Securities and Exchange Commission, there is no action, suit, investigation, litigation or proceeding affecting any Loan Party or any of its Subsidiaries, including any Environmental
Action, pending or, to the best of my knowledge, threatened before any Governmental Authority or arbitrator that (i) could be reasonably likely to have a Material Adverse Effect or (ii) purports to affect the legality, validity or enforceability of
any Loan Document or the consummation of the Transaction. 
  
 My
opinions contained in paragraph 5 above are qualified to the extent that, the validity, binding nature or enforceability of any term of the Loan Documents may be limited or otherwise affected by, and I express no opinion regarding: 
  
 (i) The effect of bankruptcy, insolvency, reorganization,
fraudulent conveyance, moratorium and other similar rights and remedies of creditors generally including, without limitation, Section 548 of the U.S. Bankruptcy Code and similar provisions of state law; 
  
 (ii) Limitations imposed by state law, federal law or
general equitable principles upon the specific enforcement of any of the remedies, covenants or the provisions of any applicable agreement and upon the availability of injunctive relief or other equitable remedies, regardless of whether enforcement
of any such agreement is considered a proceeding in equity or at law; 
  
 (iii) The effect (if any) of limitations arising from certain state and federal court decisions involving statutes, public policy or principles of equity and holding that (a) certain covenants and provisions of
lending and security agreements, including those allowing for acceleration of indebtedness due under debt instruments upon the occurrence of certain events, impose restrictions or obligations on the borrower and it cannot be demonstrated that the
enforcement of such restrictions or obligations upon the occurrence of such events is reasonably necessary for the protection of the lender; (b) under certain circumstances, purported waivers of the benefits of statutory provisions or common law
rights are unenforceable; (c) under certain circumstances, provisions declaring that the failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy are invalid; and (d) under certain
circumstances, certain self-help provisions and provisions which purport to create evidentiary standards are unenforceable; 
  
 (iv) With respect to any provisions providing for indemnification contained in the Loan Documents, the enforcement thereof may be limited
by public policy considerations; 
  
 (v) The
effectiveness or enforceability of provisions appointing one party as an attorney-in-fact for an adverse party; 
  
 (vi) The effect (if any) of limitations on the enforceability of after-default interest rate provisions, penalty provisions, forfeiture
provisions or late charge provisions;

 (vii) The enforceability of provisions relating to rights of entry or express waivers
of statutes of limitation or rights of redemption; 
  
 (viii) The validity or enforceability of any provision of the Loan Documents to the extent such provision (a) violates any law that provides that in a contract permitting one party thereto to recover attorneys’ fees, the prevailing
party in any action to enforce any provision of such contract shall be entitled to recover its reasonable attorneys’ fees; and (b) may be limited or otherwise affected by compliance with procedural requirements of Pennsylvania law relating to
the exercise of remedies by a lender; 
  
 (ix)
The enforceability under certain circumstances of provisions waiving unknown future rights and of provisions stating that rights or remedies are not exclusive, that every right or remedy is cumulative and may be exercised in addition to or with any
other right or remedy or that election of some particular remedy or remedies does not preclude recourse to one or more others; 
  
 (x) The effect (if any) of any law of any jurisdiction (other than California) in which any Lender Party is located that may limit the
rate of interest that such Lender Party may charge or collect; 
  
 (xi) Provisions in the Credit Agreement that purport to create rights of set-off in favor of participants or which provide for set-off to be made otherwise than in accordance with applicable laws; 
  
 (xii) The enforceability of provisions which purport to
establish acceptable standards of care; 
  
 (xiii) The enforceability of provisions which purport to establish consent to the subject matter jurisdiction of any federal court, or waive objections to venue or choice of forum; 
  
 (xiv) I express no opinion as to the enforceability of those
provisions of the Loan Documents that permit any party other than the Borrower to receive insurance proceeds and to apply the same to the indebtedness secured thereby; 
  
 (xv) I express no opinion as to the enforceability or effectiveness of those provisions of the Security
Agreement that purport to authorize the Collateral Agent to sign and file financing statements and certain other documents specified therein for the purpose of perfecting, confirming, continuing, enforcing or protecting the Security Interest (as
defined in the Security Agreement) granted by each Grantor (as defined in the Security Agreement), without the signature of such Grantor; and 
  
 (xvi) I express no opinion as to (a) the creation, validity, perfection, priority or enforcement of any lien on or security interest in
any real property; or (b) the creation, perfection, enforcement or priority of any assignment or transfer of any interest in leases or rents.

 My opinions in paragraphs 4 and 6 above as to compliance with certain statutes, rules and regulations
and as to the lack of any required consents or approvals of, authorizations by, or registrations, declarations or filings with certain Governmental Authorities are based upon a review of those statutes, rules and regulations which, in my experience,
are normally applicable to transactions of the type contemplated by the Loan Documents. 
  
 I express no opinion, and assume no responsibility to (i) update any of the opinions contained in the above paragraphs or (ii) notify any person as to the effect of, or consequences resulting from, any fact or
circumstance, including, without limitation, legislative or other changes in the law, occurring subsequent to the date of this opinion. 
  
 This opinion is rendered only to the Administrative Agent, the Issuing Bank, the Swing Line Bank, the Collateral Agent, the Syndication Agents, the Book
Managers, the Documentation Agents and the Lender Parties and is solely for their benefit in connection with the above transactions. This opinion may not be relied upon by the Administrative Agent, the Issuing Bank, the Swing Line Bank, the
Collateral Agent, the Syndication Agents, the Book Managers, the Documentation Agents or the Lender Parties for any other purpose, or quoted to or relied upon by any other person, firm or corporation for any purpose without my prior written consent;
provided, however, that this opinion may be delivered to and relied upon by each Lender Party that may become a party to the Credit Agreement as a Lender Party pursuant to the terms thereof, but only in connection with the transactions contemplated
by the Loan Documents, and by Bingham McCutchen LLP with respect to the opinions in paragraph 4 herein 
  
 Very truly yours, 
  
 Patrick A. Broderick 
 General Counsel

	 	Re:	 	Amended and Restated Credit Agreement dated as of July 15, 2003, among DaVita Inc., the banks, financial institutions and the institutional lenders party thereto as lenders, the
banks party thereto as issuing banks, Credit Suisse First Boston (“CSFB”), as swing line bank and administrative agent, CSFB and Banc of America Securities LLC, as the joint book running managers and joint lead arranger in respect of the
Revolving Credit Facility (as defined in the Credit Agreement) and the Term A Facility (as defined in the Credit Agreement) and CSFB as the sole book running manager and sole lead arranger in respect of the Term B Facility (as defined in the Credit
Agreement), The Bank of New York, The Bank of Nova Scotia and Wachovia Bank, National Association, as documentation agents in respect of the Revolving Credit Facility and the Term A Facility and Bank of America, N.A. as syndication agent in respect
of the Revolving Credit Facility and the Term A Facility and CSFB, as syndication agent in respect of the Term B Facility (the “Credit Agreement”) 

  
 Ladies and Gentlemen: 
  
 We have acted as special counsel to DaVita Inc., a Delaware corporation (“Borrower”) and each other Loan Party (as
defined in the Credit Agreement) in connection with the Credit Agreement. This opinion is rendered to you in compliance with 3.01 (a) of the Credit Agreement. Capitalized terms used herein without definition have the same meanings as in the Credit
Agreement. 
  
 In our capacity as such counsel, we have examined
originals, or copies identified to our satisfaction as being true copies, of such records, documents or other instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below. These records, documents
and instruments included the following: 
  
 (a)
The certificate or articles of incorporation or other organizational documents, as applicable, of each Loan Party, as amended to date;

 (b)
The bylaws, partnership agreement or operating agreement, as applicable, of each Loan Party, as amended to date; 
  
 (c) All records of proceedings and actions of the board of directors, partners or members, as applicable, of each Loan Party relating to
the Loan Documents and the transactions contemplated thereby; 
  
 (d) The Credit Agreement; 
  
 (e) The Term B Notes; 
  
 (f) UCC-1 financing statements filed by certain Credit Parties in the State of California in the form attached hereto as Exhibit A (the “California Financing Statements”); 
  
 (g) UCC-1 financing statements filed by certain Credit
Parties in the State of Delaware in the form attached hereto as Exhibit B (the “Delaware Financing Statements”); 
  
 (i) The Security Agreement; and 
  
 (j) The Intellectual Property Security Agreement by the Loan Parties in favor of the Collateral Agent (as defined in the Security
Agreement) (the “Intellectual Property Security Agreement”). 
  
 The Credit Agreement and the Term B Notes shall be referred to herein as the “Identified Documents”. 
  
 We have been furnished with, and with the Lender Parties’ consent have relied upon, certificates of officers of each Loan Party with respect to
certain factual matters, copies of which have been delivered to the Lender Parties. In addition, we have obtained and relied upon such certificates and assurances from public officials as we have deemed necessary, copies of which have been delivered
to the Lender Parties. As to any facts material to the opinions expressed herein that were not independently established or verified, we have relied upon the representations and warranties of the Loan Parties made in the Loan Documents and upon
statements and representations of officers and other representatives of the Loan Parties. In all such examinations, we have assumed the genuineness of all signatures (other than the signatures of any Loan Party in connection with any Loan Document)
on original and certified documents, and the conformity to original or certified documents of all documents submitted to us as conformed or photostatic copies. 
  

To the extent that the obligations of the Borrower and each other Loan Party may be dependent upon such matters, we have assumed for purposes of this
opinion, other than with respect to the Borrower and each other Loan Party, that each additional party to the agreements and contracts referred to herein is duly organized, validly existing and in good standing under the laws of its jurisdiction of
organization; that each such other party has the requisite corporate or other organizational power and authority to perform its obligations under such agreements and contracts, as applicable; and that such agreements and contracts have been duly
authorized, executed and delivered by, and each of them constitutes the legally valid and binding obligation of, such other parties, as applicable, enforceable

against such other parties in accordance with their respective terms. Except as expressly covered in this opinion, we are not expressing any opinion as to
the effect of compliance by any Lender Party with any state or Federal laws or regulations applicable to the transactions because of the nature of any of its businesses. 
  
 We have not made or undertaken to make any investigation of the state of title to any of the Collateral (as defined in the
Security Agreement) and we express no opinion concerning title to any property included in the Collateral. You have advised us that in rendering the opinions set forth below we may assume that (i) with respect to the Security Agreement and the
Intellectual Property Security Agreement, Borrower and each other Loan Party has “rights” within the meaning of Section 9203(b)(2) of the Uniform Commercial Code of the State of California (the “California UCC”) and/or Section
9-203(b)(2) of the Uniform Commercial Code of the State of Delaware (the “Delaware UCC”), as applicable, in the Collateral, consistent with the purposes of the Security Agreement; (ii) each Secured Party under the Security Agreement and
the Intellectual Property Security Agreement will act in good faith and will seek to enforce its rights and remedies under the Loan Documents in a commercially reasonable manner; and (iii) no termination statements have been filed with respect to
the California Financing Statements or the Delaware Financing Statements. 
  
 We have investigated such questions of law for the purpose of rendering this opinion as we have deemed necessary. We are attorneys duly admitted and qualified to practice only in the State of California, and we are
opining herein only as to the effect on the subject transaction of the laws of the State of California, the Delaware General Corporation Law, the Delaware UCC and United States Federal law. We are not opining on, and we assume no responsibility as
to the applicability to or the effect on any of the matters covered herein of, the laws of any other jurisdiction. In addition, we do not express any opinion as to any law applicable to the environment, real estate, taxes, “bulk sales”,
securities, “blue sky” or antifraud matters. We note that the Credit Agreement provides that it shall be governed by, and construed and interpreted in accordance with, the laws of the State of New York, and that the other Loan 

 
 Documents contain similar provisions and that we are not opining herein
under the laws of the State of New York. With your permission, except to the extent otherwise contemplated by paragraph 14 below, we are delivering the opinions herein assuming that the Credit Agreement and the other Loan Documents are governed by
the internal laws of the State of California (without giving effect to conflict of law principles). 
  
 On the basis of the foregoing, and in reliance thereon, and subject to the limitations, qualifications and exceptions set forth below, we are of the
opinion that: 
  
 1. The Borrower is a
corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation and has all requisite corporate power and authority to own and operate its properties and to carry on its business as now
conducted. 
  
 2. Each of the Guarantors of
Borrower which is identified on Exhibit C attached hereto is an entity duly formed, validly existing and, to the extent such concept is applicable in good standing under the laws of its jurisdiction of organization and has all requisite
corporate, partnership or limited liability company power and authority, as applicable, to own and operate its properties and to carry on its business as now conducted.

 3. The execution, delivery and performance by each Loan Party of each Identified
Document to which it is or is to be a party, and the consummation of the Transaction, are within such Loan Party’s corporate, partnership or limited liability company powers, as applicable, have been duly authorized by all necessary corporate,
partnership or limited liability company, action, as applicable, and do not (i) contravene such Loan Party’s Constitutive Documents, or (ii) violate any present Federal, Delaware corporation or California statute, rule or regulation binding on
such Loan Party. 
  
 4. The Identified Documents
have been duly executed and delivered by each Loan Party and constitute the legally valid and binding obligations of such Loan Party, enforceable against such Loan Party in accordance with their respective terms. 
  
 5. No consents or approvals of, and no other authorization
or approval or other action by, and no notice to or filing with, any Federal, Delaware or California Governmental Authority is required for (i) the due execution, delivery, recordation, filing or performance by any Loan Party of any Identified
Document to which it is or is to be a party, or for the consummation of the Transaction, (ii) the grant by any Loan Party of the Liens granted by it pursuant to the Collateral Documents, (iii) the perfection or maintenance of the Liens created under
the Collateral Documents on such of the Collateral located in the United States in which a Lien may be perfected by the filing of financing statements, the recordation of security agreements with the U.S. Patent and Trademark Office or the U.S.
Copyright Office or the delivery of Collateral or (iv) the exercise by any Secured Party of its rights under the Loan Documents or the remedies in respect of the Collateral pursuant to the Collateral Documents, except for (A) the authorizations,
approvals and actions on Schedule 4.01(d) to the Credit Agreement, all of which have been duly obtained and are in full force and effect (except as may otherwise be noted in such schedule), (B) filings, notices, recordings and other similar actions
necessary for the creation or perfection or continuation of the Liens and security interests contemplated by the Loan Documents or (C) actions required in connection with the exercise of the rights of a secured creditor by laws or regulations
affecting such rights generally. 
  
 6. The
provisions of the Security Agreement are sufficient to create a valid security interest, as security for the payment of all Secured Obligations (as defined in the Security Agreement), in favor of the Secured Parties in the Collateral that is of a
type in which a security interest can be created under the California UCC and federal law governing Trademarks. 
  
 7. The California Financing Statements are in appropriate form to perfect the security interests described in paragraph 6 to the extent
security interests in the various types of Collateral can be perfected by filing under the provisions of the California UCC and the proper place to file the California Financing Statements is in the office of the Secretary of State of the State of
California and no filing in any other place is necessary under the California UCC to perfect a security interest in any such Collateral. Assuming that such Financing Statements have been properly filed in the office of the Secretary of State of the
State of California, and the applicable filing fees have been paid, the security interests in favor of the Secured Parties in the Collateral have been perfected to the extent security interests in the various types of Collateral can be perfected by
filing under, and the perfection of which is governed by, the provisions of the California UCC.

 8. The Delaware Financing Statements are in appropriate form to perfect the security
interests described in paragraph 6 to the extent security interests in the various types of Collateral can be perfected by filing under the provisions of the Delaware UCC and the proper place to file the Delaware Financing Statements is in the
office of the Secretary of State of the State of Delaware and no filing in any other place is necessary under the Delaware UCC to perfect a security interest in any such Collateral. Assuming that such Financing Statements have been properly filed in
the office of the Secretary of State of the State of Delaware, and the applicable filing fees have been paid, the security interests in favor of the Secured Parties in the Collateral have been perfected to the extent security interests in the
various types of Collateral can be perfected by filing under, and the perfection of which is governed by, the provisions of the Delaware UCC. 
  
 9. Assuming that the Financing Statements relating to the Trademarks (as defined in the Intellectual Property Security Agreement) have
been properly filed in the office of the Secretary of State of the State of California or the office of the Secretary of State of the State of Delaware, as applicable, and the Intellectual Property Security Agreement has been properly recorded in
the United States Patent and Trademark Office (and similar filings are made with the United States Patent and Trademark Office for federal Trademarks subsequently acquired), the security interest in favor of the Collateral Agent in such Trademarks
is a perfected security interest under the California UCC or the Delaware UCC, as applicable, and affords to the Collateral Agent all benefits and protections available to secured parties making such filings with the United States Patent and
Trademark Office under applicable federal Trademark law. 
  
 10. In the case of the Security Collateral (as defined in the Security Agreement) consisting of certificated securities or evidenced by instruments, upon the delivery of the certificates representing such certificated
securities and delivery of such instruments to the Collateral Agent, in each case duly endorsed or accompanied by duly executed instruments of assignment or transfer in blank, the security interest in such Security Collateral in favor of the Secured
Parties will constitute a perfected security interest therein. Assuming the Collateral Agent acquires its interest in such certificated securities included in the Security Collateral in good faith and without notice of any adverse claims, the
Collateral Agent will acquire its security interest in such certificated securities included in the Security Collateral free of any adverse claims within the meaning of Section 8102 of the California UCC or Section 8-102 of the Delaware UCC, as
applicable. 
  
 11. To the best of our knowledge,
except as described on Schedule 4.01(f) of the Credit Agreement or disclosed prior to the Closing Date in the Borrower’s filings made with the Securities and Exchange Commission, there is no action, suit, investigation, litigation or proceeding
affecting any Loan Party, including any Environmental Action, pending or threatened before any Governmental Authority or arbitrator that (i) could be reasonably likely to have a Material Adverse Effect or (ii) purports to affect the legality,
validity or enforceability of any Loan Document or the consummation of the Transaction. 
  
 12. The making of the Term C Advances and the application of the proceeds thereof as provided in the Credit Agreement do not violate
Regulation T, U or X of the Board of Governors of the Federal Reserve System.

 13. Neither the Borrower nor any of its Subsidiaries is subject to regulation under
the Public Utility Holding Company Act of 1935, as amended, the Federal Power Act, as amended, or the Investment Company Act of 1940, as amended. 
  
 14. With respect to the enforceability of the choice of the law of the State of New York to govern the Loan Documents, although the issue
is not free from doubt, we are of the opinion that a California state court or a federal court applying California law should, in a properly litigated case, uphold the parties’ selection of New York law as the governing law for purposes of the
Loan Documents except that we express no opinion as to the extent that (i) application of the laws of the State of New York to certain provisions of the Loan Documents would be or might be inconsistent with the public policy of the State of
California or (ii) matters relating to the attachment, perfection, priority or enforcement of the Liens created by the Security Agreement and the Intellectual Property Security Agreement may be governed by the laws of other jurisdictions.

  
 Our opinions contained in paragraphs 5, 6, 7, 8, 9 and 10
above are qualified as follows: 
  
 A. Such
opinions are limited to Articles 8 and 9 of the California UCC and the Delaware UCC, respectively, and the matters under Federal Trademark law set forth in such opinions, and therefore such opinions do not address (i) laws of jurisdictions other
than California or Delaware and of California or Delaware except for Articles 8 and 9 of the California UCC or the Delaware UCC, respectively, and Federal law applicable to the Trademarks, (ii) collateral of a type not subject to Articles 8 and 9 of
the California UCC or the Delaware UCC, respectively, or Federal law applicable to the Trademarks; and (iii) what law governs the perfection of the security interests granted in the Collateral under Section 9301 of the California UCC or Section
9-301 of the Delaware UCC; 
  
 B. In the case of
proceeds, continuation of perfection of the Secured Parties’ security interests therein is limited to the extent set forth in Section 9315 of the California UCC or Section 9-315 of the Delaware UCC; 
  
 C. In the case of property that becomes Collateral after the
date hereof, Section 552 of the U.S. Bankruptcy Code limits the extent to which property acquired by a debtor after the commencement of a case under the U.S. Bankruptcy Code may be subject to a security interest arising from a security agreement
entered into by the debtor before the commencement of such case; 
  
 D. We express no opinion as to the adequacy of the description of Collateral as defined in the Documents, to the extent such description includes terms which are not defined under Article 9 of the California UCC or
the Delaware UCC, respectively; or as to the scope of the term “general intangibles” as used in the Loan Documents; 
  
 E. We express no opinion as to the creation, continuation or perfection of the security interest in any Collateral to the extent (i) it is
governed by the laws of a jurisdiction other than the State of California or Delaware or (ii), with respect to a security interest perfected by

possession, it is held by the Collateral Agent other than in the State of California or the State of Delaware; 
  
 F. We express no opinion as to the creation or perfection of
any security interest or lien except as expressly set forth in paragraphs 6, 7, 8, 9 and 10 nor do we express any opinion on the priority of any such security interest or lien except as expressly set forth in paragraph 10; 
  
 G. In the case of goods, we express no opinion regarding the
security interest of a Secured Party in any goods that are in accession to, or commingled or processed with other goods to the extent that the security interest of the Secured Party is limited by Section 9335 or 9336 of the California UCC or Section
9-335 or 9-336 of the Delaware UCC; 
  
 H. We
express no opinion with respect to any Collateral of a type described in Section 9501(a)(1) of the California UCC or Section 9-501(a)(1) of the Delaware UCC or represented by a certificate of title; 
  
 I. We call to your attention that additional filings under
the California UCC or the Delaware UCC may be required upon (i) the change of location of the debtor, (ii) the change of the name or organizational structure of the debtor, (iii) removal of the tangible collateral from the applicable state, and (iv)
changes occurring which may cause such financing statements to become seriously misleading; 
  
 J. We advise you that under the California UCC and/or the Delaware UCC, events occurring subsequent to the date hereof may affect any security interest subject to the California UCC or the Delaware UCC, respectively,
including, but not limited to Sections 9330 and 9331 of the California UCC and Sections 9-330 and 9-331 of the Delaware UCC with respect to subsequent purchasers of the Collateral; and 
  
 K. We advise you that the rights of the Secured Party in the Collateral may be subject to the rights of account debtors,
claims and defenses of account debtors and the terms of agreements with account debtors. 
  
 Our opinions contained in paragraph 4 above are qualified to the extent that, the validity, binding nature or enforceability of any term of the Loan Documents may be limited or otherwise affected by, and we express no
opinion regarding: 
  
 (i) The effect of
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and other similar rights and remedies of creditors generally including, without limitation, Section 548 of the U.S. Bankruptcy Code and similar provisions of state law;

  
 (ii) Limitations imposed by state law,
federal law or general equitable principles upon the specific enforcement of any of the remedies, covenants or the provisions of any applicable agreement and upon the availability of injunctive relief or other equitable remedies, regardless of
whether enforcement of any such agreement is considered a proceeding in equity or at law;

 Page 18 
  

 (iii) The effect of California statutory provisions and case law that provide that,
in certain circumstances, a surety or guarantor may be exonerated if the creditor materially alters the original obligation of the principal without the consent of the guarantor, elects remedies for default which impair the subrogation rights of the
surety or guarantor against the principal or otherwise takes any action without notifying the guarantor which materially prejudices the surety or guarantor. Union Bank v. Gradsky, 265 Cal. App. 2d 40 (1968). However, there is also authority
to the effect that a surety or guarantor may validly waive such rights if such waivers are expressly set forth in the guaranty. Krueger v. Bank of America, 145 Cal. App. 3d 204, 193 Cal. Rptr. 322 (1983) and Section 2856 of the California
Civil Code; but see Cathay Bank v. Lee, 14 Cal. App. 4th 1533, 18 Cal. Rptr. 2d 420 (1993), in which the court held that to be enforceable a waiver of a surety or a guarantor’s rights must be sufficiently explicit. Therefore, we express
no opinion with respect to the effect of (a)(1) any modification or amendment made subsequent to the date hereof of the obligations of the Borrower or any Guarantor which materially increases such obligations and correspondingly the Guarantors’
obligations in respect thereof, (2) any election of remedies by the Collateral Agent, the Administrative Agent or any Lender Party following the occurrence of an event of default with respect to the obligations of the Borrower; (3) any other action
by the Collateral Agent, the Administrative Agent or any Lender Party which materially prejudices the Guarantors pursuant to the Loan Documents, if, in any such instance, such modification, election or action occurs without notice to the Guarantors
and without granting to the Guarantors an opportunity to cure any default by the Borrower; or (b) any purported waiver by the Guarantor that does not comply with any requirements of explicitness and/or specificity imposed by any court; 

 
 (iv) The effect (if any) of limitations arising from
certain state and federal court decisions involving statutes, public policy or principles of equity and holding that (a) certain covenants and provisions of lending and security agreements, including those allowing for acceleration of indebtedness
due under debt instruments upon the occurrence of certain events, impose restrictions or obligations on the borrower and it cannot be demonstrated that the enforcement of such restrictions or obligations upon the occurrence of such events is
reasonably necessary for the protection of the lender; (b) under certain circumstances, purported waivers of the benefits of statutory provisions or common law rights are unenforceable; (c) under certain circumstances, provisions declaring that the
failure to exercise or delay in exercising rights or remedies will not operate as a waiver of any such right or remedy are invalid; and (d) under certain circumstances, certain self-help provisions and provisions which purport to create evidentiary
standards are unenforceable; 
  
 (v) With respect
to any provisions providing for indemnification contained in the Loan Documents, the enforcement thereof may be limited by public policy considerations; 
  
 (vi) The effectiveness or enforceability of provisions appointing one party as an attorney-in-fact for an adverse party; 
  
 (vii) The effect (if any) of limitations on the
enforceability of after-default interest rate provisions, penalty provisions, forfeiture provisions or late charge provisions;

 (viii) The enforceability of provisions relating to rights of entry or express
waivers of statutes of limitation or rights of redemption; 
  
 (ix) The validity or enforceability of any provision of the Loan Documents to the extent such provision (a) violates the law of the State of California that provides that in a contract permitting one party thereto to
recover attorneys’ fees, the prevailing party in any action to enforce any provision of such contract shall be entitled to recover its reasonable attorneys’ fees; and (b) may be limited or otherwise affected by compliance with procedural
requirements of California law relating to the exercise of remedies by a lender; 
  
 (x) The enforceability under certain circumstances of provisions waiving unknown future rights and of provisions stating that rights or
remedies are not exclusive, that every right or remedy is cumulative and may be exercised in addition to or with any other right or remedy or that election of some particular remedy or remedies does not preclude recourse to one or more others;

  
 (xi) The effect (if any) of any law of any
jurisdiction (other than California) in which any Lender Party is located that may limit the rate of interest that such Lender Party may charge or collect; 
  
 (xii) The enforceability of provisions which purport to create rights of set-off in favor of participants or which provide for set-off to
be made otherwise than in accordance with applicable laws; 
  
 (xiii) The enforceability of provisions which purport to establish acceptable standards of care; 
  
 (xiv) The enforceability of provisions which purport to establish consent to the subject matter jurisdiction of any federal court, or
waive objections to venue or choice of forum; 
  
 (xv) The enforceability of those provisions of the Loan Documents that permit any party other than the Borrower to receive insurance proceeds and to apply the same to the indebtedness secured thereby; and 
  
 (xvi) We express no opinion as to (a) the creation,
validity, perfection, priority or enforcement of any lien on or security interest in any real property; or (b) the creation, perfection, enforcement or priority of any assignment or transfer of any interest in leases or rents. 
  
 Our opinions in paragraphs 3 and 5 above as to compliance with certain
statutes, rules and regulations and as to the lack of any required consents or approvals of, authorizations by, or registrations, declarations or filings with certain governmental authorities are based upon a review of those statutes, rules and
regulations which, in our experience, are normally applicable to transactions of the type contemplated by the Loan Documents. We express no opinion as to requirements imposed on the Borrower or the Guarantors under Medicare, Medicaid, or other
statutes specifically applicable by virtue of the fact that the Borrower and Guarantors are in the health care business.

 As used in this opinion, the phrase “to the best of our knowledge” signifie that, in the
course of our representation of the Loan Parties, no facts have come tc our attention that would give us actual knowledge or actual notice that any such opinions or other matters are not accurate. Further, the words “to the best of our
knowledge” as used in this opinion are intended to be limited to (i) the actual knowledge of the attorneys within our firm who have been directly involved representing the Loan Parties in connection with the transactions contemplated by the
Loan Documents or who we reasonably believe have knowledge of the affairs of the Loan Parties, and (ii) inquiry of officers of the Borrower and the Guarantors. No inference as to our knowledge of the existence or nonexistence o any fact should, or

 Reference is made to the above-captioned Credit Agreement and to the
Subsidiary Guarantee referred to therein (such Subsidiary Guarantee, as in effect on the date hereof and as it may be further amended, supplemented or otherwise modified hereafter from time to time, the “Guarantee”).
Capitalized terms not otherwise defined in this Guarantee Supplement shall have the same meanings as specified therefor in the Credit Agreement or the Guarantee. 
  
 SECTION 1. Guarantee; Limitation of Liability. (a) Each of the undersigned hereby unconditionally and irrevocably
guarantees on a joint and several basis with the other Guarantors the punctual payment when due, whether at scheduled maturity or at a date fixed for prepayment or by acceleration, demand or otherwise, of all of the Obligations of the Borrower now
or hereafter existing under or in respect of the Finance Documents (including, without limitation, any extensions, modifications, substitutions, amendments or renewals of any or all of the foregoing Obligations), whether direct or indirect, absolute
or contingent, and whether for principal, interest, premium, fees, indemnification payments, contract causes of action, costs, expenses or otherwise (such Obligations being the “Guaranteed Obligations”), and agrees to pay any
and all expenses (including, without limitation, reasonable fees and expenses of counsel) incurred by the Administrative Agent or any of the Guaranteed Parties in enforcing any rights under this Guarantee Supplement or the Guarantee, on the terms
and subject to the limitations set forth in the Guarantee, as if it were an original party thereto. Without limiting the generality of the foregoing, each of the undersigned’s liability shall extend to all amounts that constitute part of the
Guaranteed Obligations and would be owed by any of the other Loan Parties to the Administrative Agent or any of the Guaranteed Parties under or in respect of the Finance Documents but for the fact that they are unenforceable or not allowable due to
the existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party. 







 (b) Each of the undersigned, and by their acceptance of this Guarantee Supplement, the Administrative
Agent and each of the Guaranteed Parties, hereby confirm that it is the intention of all such Persons that this Guarantee Supplement, the Guarantee and the Obligations of the undersigned hereunder and thereunder not constitute a fraudulent transfer
or conveyance for purposes of the United States Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state Requirements of Law covering the protection of creditors’ rights
or the relief of debtors to the extent applicable to this Guarantee Supplement, the Guarantee and the Obligations of the undersigned hereunder and thereunder. To effectuate the foregoing intention, each of the undersigned, the Administrative Agent
and each of the Guaranteed Parties hereby irrevocably agree that the Guaranteed Obligations and all of the other liabilities of the undersigned under this Guarantee Supplement and the Guarantee shall be limited to the maximum amount as will, after
giving effect to such maximum amount and all of the other contingent and fixed liabilities of the undersigned that are relevant under such Requirements of Law, and after giving effect to any collections from, any rights to receive contributions
from, or any payments made by or on behalf of, any of the other Guarantors in respect of the Obligations of such other Guarantor under the Guarantee, result in the Guaranteed Obligations and all of the other liabilities of the undersigned under this
Guarantee Supplement and the Guarantee not constituting a fraudulent transfer or conveyance. 
  
 (c) Each of the undersigned hereby unconditionally and irrevocably agrees that, in the event any payment shall be required to be made to the Guaranteed Parties under this Guarantee Supplement, the Guarantee or any
other guarantee, the undersigned will contribute, to the fullest extent permitted by applicable law, such amounts to each of the other Guarantors and each other guarantor so as to maximize the aggregate amount paid to the Guaranteed Parties under or
in respect of the Finance Documents. 
  
 SECTION 2. Obligations
Under the Guarantee. Each of the undersigned hereby agrees, as of the date first above written, to be bound as a Guarantor by all of the terms and conditions of the Guarantee to the same extent as each of the other Guarantors. Each of the
undersigned further agrees, as of the date first above written, that each reference in the Guarantee to an “Additional Guarantor” or a “Guarantor” shall also mean and be a reference to the undersigned, and each
reference in any other Loan Document to a “Guarantor” or a “Loan Party” shall also mean and be a reference to the undersigned. 
  

SECTION 3. Governing Law; Jurisdiction; Etc. (a) This Guarantee Supplement shall be governed by, and construed in accordance with, the laws of
the State of New York. 
  
 (b) Each of the undersigned hereby
irrevocably and unconditionally submits, for itself and its property and assets, to the nonexclusive jurisdiction of any New York state court or any federal court of the United States of America sitting in New York City, New York, and any appellate
court from any thereof, in any action or proceeding arising out of or relating to this Guarantee Supplement, the Guarantee or any of the other Finance Documents to which it is a party, or for recognition or enforcement of any judgment in respect
thereof, and the undersigned hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in any such New York state court or, to the fullest extent permitted by applicable
law, in any such federal court. Each of the undersigned hereby irrevocably consents to the service of copies of any summons and complaint and any other process which may be served in any such action or proceeding by certified mail, return receipt
requested, or by delivering a copy of such process to such party, at its address set forth below its name on the signature page to this Guarantee Supplement, or by any other method permitted by applicable law. Each of the undersigned hereby 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 applicable law. Nothing in this Guarantee Supplement or the Guarantee
shall affect any right that any party may otherwise have to bring any action or proceeding 







 
relating to this Guarantee Supplement, the Guarantee or any of the other Finance Documents in the courts of any jurisdiction. 
  
 (c) Each of the undersigned irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Guarantee Supplement or any of the other Finance Documents to
which it is a party in any New York state court or federal court. Each of the undersigned hereby irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or
proceeding in any such court. 
  
 SECTION 4. WAIVER OF JURY
TRIAL. EACH OF THE UNDERSIGNED IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS GUARANTEE SUPPLEMENT, THE GUARANTEE, ANY OF
THE OTHER FINANCE DOCUMENTS, ANY DOCUMENTS DELIVERED PURSUANT TO THE FINANCE DOCUMENTS, THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY OR THE ACTIONS OF ANY OF THE ADMINISTRATIVE AGENT OR ANY OF THE OTHER GUARANTEED PARTIES IN THE NEGOTIATION,
