        accordance with GAAP, as in effect from time to time; provided that, if the Borrower notifies the Agent that the Borrower requests an amendment to any
        provision hereof to eliminate the effect of any change occurring after the date hereof in GAAP or in the application thereof on the operation of such provision (or if the Agent notifies the Borrower that the Required Banks request an amendment to

        AMOUNTS AND TERMS OF THE ADVANCES

    Section 2.01          The Revolving Credit Advances.   (a) Each Bank severally agrees, on the terms and conditions hereinafter set forth, to make Revolving Credit
        Advances in Dollars to the Borrower from time to time on any Business Day during the period from the Effective Date until the Termination Date for such Bank in an aggregate amount not to exceed such Bank’s Unused Revolving Credit Commitment at such
        time; provided that no Revolving Credit Advance shall be required to be made, except as a part of a Revolving Credit Borrowing that is in an aggregate
        amount not less than $10,000,000 in the case of Eurodollar Rate Advances and $5,000,000 in the case of Base Rate Advances and in an integral multiple of $1,000,000, and each Revolving Credit Borrowing shall consist of Revolving Credit Advances of
        the same Type made on the same day by the Banks according to their Pro Rata Shares.  Within the limits of each Bank’s Unused Revolving Credit Commitment in effect from time to time, the Borrower may borrow, prepay pursuant to Section 2.10 and
        reborrow under this Section 2.01.  The Borrower agrees to give a Notice of Revolving Credit Borrowing in accordance with Section 2.02(a) as to each Revolving Credit Advance.

    (b)          Letters of Credit.  The Issuing Banks, the Banks and the Borrower agree that effective as of the Effective Date, the Existing Letters of Credit
        shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement.  Each Issuing Bank agrees, on the terms and conditions hereinafter set forth, to issue letters of credit (collectively, the
        “Letters of Credit”, and each a “Letter of Credit”) for the
        account of the Borrower (such issuance, and any funding of a draw thereunder, to be made by the 

     

      

    
      19

      
        


    

     Issuing Banks in reliance on the agreements of the other Banks pursuant to Section 2.03) from time to time on
        any Business Day during the period from the Effective Date until the earlier of (y) the Termination Date for all the Banks and (z) five (5) Business Days prior to the latest Stated Termination Date for any Bank in an aggregate Available Amount
        (i) for all Letters of Credit issued by the Issuing Banks not to exceed at any time the aggregate Letter of Credit Commitments at such time minus
        all Letter of Credit Advances outstanding at such time, (ii) for all Letters of Credit issued by any Issuing Bank, not to exceed at any time the Letter of Credit Commitment of such Issuing Bank at such time minus all Letter of Credit Advances owed to such Issuing Bank outstanding at such time (or such greater amount as such Issuing Bank shall approve), and (iii) for each such
        Letter of Credit not to exceed an amount equal to the Unused Revolving Credit Commitments of the Banks at such time; provided, however, that no Issuing Bank shall be required to issue a Letter of Credit if any Bank is a Defaulting Bank or Potential Defaulting Bank unless the
        Borrower has deposited cash collateral to the extent required under Section 2.06(c)(ii).  If the Stated Termination Date for all Banks is not the same and the aggregate Available Amount of the Letters of Credit that have an expiration date later
        than the Stated Termination Date for any Non-Extending Bank will exceed the Unused Revolving Credit Commitments as of such Stated Termination Date, then the Borrower shall grant a first priority perfected security interest in, and deliver to
        (A) each Issuing Bank that is an Extending Bank, for such Issuing Bank’s sole benefit, an amount in Dollars and in same day funds equal to each applicable Non-Extending Bank’s Pro Rata Share of all outstanding Letters of Credit issued by such
        Issuing Bank, to be held as cash collateral by such Issuing Bank under the sole control and dominion of such Issuing Bank and subject to the terms of this Agreement and (B) any Issuing Bank that is a Non-Extending Bank, for such Issuing Bank’s sole
        benefit, an amount in Dollars and in same days funds equal to the Available Amount of all outstanding Letters of Credit issued by such Issuing Bank (but without duplication of amounts, if any, delivered in respect of such Letters of Credit pursuant
        to Section 2.01(b)(iii)(A)), to be held as cash collateral by such Issuing Bank under the sole control and dominion of such Issuing Bank and subject to the terms of this Agreement.  Within the limits referred to above, the Borrower may request the
        issuance of Letters of Credit under this Section 2.01(b), repay any Letter of Credit Advances resulting from drawings thereunder and request the issuance of additional Letters of Credit under this Section 2.01(b).

    (c)          Swingline Advances.

              (i)

            	
              Subject to the terms and conditions set forth herein, the Swingline Bank,
                  in reliance on the agreements of the other Banks pursuant to Section 2.01(c)(iii), shall, on the terms and conditions hereinafter set forth, make Swingline Advances in Dollars to the Borrower from time to time on any Business Day during
                  the period from the Effective Date until the Termination Date for the Swingline Bank in an aggregate amount not to exceed the lesser of (i) the Swingline Sublimit and (ii) for each such Swingline Advance, the Unused Revolving Credit
                  Commitments of the Banks at such time; provided that the Swingline Bank shall not be required to make a Swingline Advance to refinance an
                  outstanding Swingline Advance; and provided further
                  that the Swingline Bank shall not be required to make Swingline Advances if any Bank is a Defaulting Bank or Potential Defaulting Bank unless the Borrower has deposited cash collateral to the extent required under Section 2.06(c)(ii). 
                  Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay pursuant to Section 2.10 and reborrow under this Section 2.01(c).  Immediately upon the making of a Swingline Advance,
                  each Bank shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swingline Bank a risk participation in such Swingline Advance in an amount equal to such Bank’s Pro Rata Share of such Swingline
                  Advance.

            


    

    
      	
              (ii)

            	
              Each Swingline Advance shall be made on notice in substantially the form
                  of Exhibit B-3 (a “Notice of Swingline Advance”), given not later than 3:00 P.M. (New York City time), on the day of a proposed Swingline Advance,
                  by the Borrower to the Agent, which shall give the Swingline Bank prompt notice thereof by facsimile or other electronic communication (e-mail).  Each Notice of Swingline Advance shall be consistent with the requirements of this
                  Section 2.01(c) and shall be by facsimile or other electronic communication (e-mail) (or by telephone notice promptly confirmed by a written, fax or electronic communication (e-mail)), specifying therein the requested (A) date of such
                  Swingline Advance and (B) amount of such Swingline Advance.  The Swingline Bank shall, before 4:00 P.M. (New York City time) on the date of such Swingline Advance, make available, in same day funds, such Swingline Advance to the Borrower
                  by means of a credit to the general deposit account of the Borrower with the Swingline Bank; provided that the Swingline Bank shall not make any
                  Swingline Advances if the applicable conditions set forth in Article III have not been fulfilled.  Each Swingline Advance shall be a Base Rate Advance at all times.  Each Swingline Advance shall be in a minimum amount of $1,000,000 and in
                  an integral multiple of $1,000,000.

            


    

    
      	
              (iii)

            	
              Upon written demand by the Swingline Bank with an outstanding Swingline
                  Advance, with a copy of such demand to the Agent, each Bank shall make a Base Rate Advance in an amount equal to such Bank’s Pro Rata Share of such outstanding Swingline Advance as of the date of such demand (and the Agent may apply cash
                  collateral available with respect to any Defaulting Bank’s ratable share).  Such request shall be made in accordance with the requirements of Section 2.02, without regard to the minimum and multiples specified therein for the principal
                  amount of Base Rate Advances, but subject to the amount of the Unused Revolving Credit Commitments and the conditions set forth in Section 3.02.  Each Bank shall on (A) the Business Day on which demand therefor is made by the Swingline
                  Bank, provided that notice of such demand is given not later than 11:00 A.M. (New York City 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, make available to the Agent for the account of the Swingline Bank, in same day funds, such Bank’s Pro Rata Share of such Swingline Advance.  Promptly after
                  receipt thereof, the Agent shall transfer such funds to the Swingline Bank.

            


    

    
      	
              (iv)

            	
              If for any reason any Swingline Advance cannot be refinanced by such a
                  Revolving Credit Borrowing, the request for Base Rate Advances made by the Swingline Bank as set forth herein shall be deemed to be a request by the Swingline Bank that each of the Banks, and each of the Banks absolutely and
                  unconditionally agrees to, fund its risk participation in such Swingline Advance by purchasing from the Swingline Bank, and the Swingline Bank shall sell and assign to each such Bank, such Bank’s Pro Rata Share of such outstanding
                  Swingline Advance as of the date of such purchase, by making available for the account of its Applicable Lending Office to the Agent for the account of the Swingline Bank, by deposit to the Agent’s Account, in same day funds, an amount
                  equal to the portion of the outstanding principal amount of such Swingline Advance to be purchased by such Bank.  Promptly after receipt thereof, the Agent shall transfer such funds to the Swingline Bank.  The Borrower hereby agrees to
                  each such sale and assignment.  Upon any such assignment by the Swingline Bank to any Bank of a portion of a Swingline Advance, the Swingline Bank represents and warrants to such Bank that such Swingline 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 Swingline Advance, the Loan Documents or the Borrower.  Each Bank
                  acknowledges and agrees that its obligation to acquire participations in Swingline Advances pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and
                  continuance of a Default or Event of Default or reduction or termination of the Revolving Credit Commitments; and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.  The purchase of
                  participations in a Swingline Advance pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

            


    

    
      	
              (v)

            	
              If and to the extent that any Bank shall not have so made its Pro Rata
                  Share of the amount of such Swingline Advance available to the Agent for the account of the Swingline Bank pursuant to this Section 2.01(c), such Bank agrees to pay to the Agent for the account of the Swingline Bank forthwith on demand
                  its Pro Rata Share of such amount together with interest thereon, for each day from the date of demand by the Swingline Bank until the date such Bank pays its Pro Rata Share of such amount to the Agent, at the Federal Funds Rate for its
                  account or the account of the Swingline Bank, as applicable.  If such Bank shall pay to the Agent its Pro Rata Share of such amount for the account of the Swingline Bank on any Business Day, such amount so paid in respect of principal
                  shall constitute a Revolving Credit Advance or funded participation made by such Bank on such Business Day for purposes of this Agreement, and the outstanding principal amount of the Swingline Advance made by the Swingline Bank shall be
                  reduced on such Business Day by such amount so paid in respect of principal.

            


    

    
      	
              (vi)

            	
              The failure of any Bank to pay its Pro Rata Share of any Swingline Advance
                  to be made by it on the date specified in Section 2.01(c) shall not relieve any other Bank of its obligation hereunder to pay its Pro Rata Share of any Swingline Advance on such date, but no Bank shall be responsible for the failure of
                  any other Bank to pay its Pro Rata Share of any Swingline Advance to be made by such other Bank on such date.

    Section 2.02          Making the Revolving Credit Advances.   (a) Each Revolving Credit Borrowing shall be made on notice in substantially the form of Exhibit B-1 (a “Notice of Revolving Credit Borrowing”), given not later than 11:00 A.M. (New York City time) (i) on the date of a proposed Revolving Credit Borrowing comprised
        of Base Rate Advances and (ii) on the third Business Day prior to the date of a proposed Revolving Credit Borrowing comprised of Eurodollar Rate Advances, by the Borrower to the Agent, which shall give to each Bank prompt notice thereof by
        facsimile or other electronic communication (e-mail). 

     

      

    
      22

      
        


    

     Each Notice of Revolving Credit Borrowing shall be consistent with the requirements of Section 2.01(a) and shall be by facsimile or
        other electronic communication (e-mail) (or by telephone notice promptly confirmed by a written, fax or electronic communication (e-mail)), specifying therein the requested (i) date of such Revolving Credit Borrowing, (ii) Type of Revolving Credit
        Advances comprising such Revolving Credit Borrowing, (iii) aggregate amount of such Revolving Credit Borrowing, and (iv) if such Revolving Credit Borrowing is to be comprised of Eurodollar Rate Advances, the initial Interest Period for each such
        Revolving Credit Advance.  Each Bank shall, before 2:00 P.M. (New York City time) on the date of such Revolving Credit Borrowing, make available for the account of its Applicable Lending Office to the Agent at its address referred to in
        Section 8.02, in same day funds, such Bank’s Pro Rata Share of such Revolving Credit Borrowing.  After the Agent’s receipt of such funds, the Agent will make such funds available to the Borrower at the Agent’s aforesaid address; provided that the Agent shall not be required to make such funds available if the applicable conditions set forth in Article III have not been fulfilled.

    (b)          Notwithstanding any other provision in this Agreement, at no time shall there be more than ten (10) Revolving Credit Borrowings outstanding; provided
        that for purposes of the limitation set forth in this sentence, all Revolving Credit Borrowings consisting of Base Rate Advances shall constitute a single Revolving Credit Borrowing.

    (c)          Each Notice of Revolving Credit Borrowing shall be irrevocable and binding on the Borrower.  In the case of any Revolving Credit Borrowing that the related Notice of Revolving Credit Borrowing specifies is to be comprised of Eurodollar
        Rate Advances, the Borrower shall indemnify each Bank against any loss, cost or expense incurred by such Bank as a result of any failure to fulfill on or before the date specified in such Notice of Revolving Credit Borrowing for such Revolving
        Credit Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds
        acquired by such Bank to fund the Revolving Credit Advance to be made by such Bank as part of such Revolving Credit Borrowing when such Revolving Credit Advance, as a result of such failure, is not made on such date.

    (d)          Unless the Agent shall have received notice from a Bank prior to the time of any Revolving Credit Borrowing that such Bank will not make available to the Agent such Bank’s Pro Rata Share of such Revolving Credit Borrowing, the Agent may
        assume that such Bank has made such Pro Rata Share available to the Agent on the date of such Revolving Credit Borrowing in accordance with Section 2.02(a) and the Agent may, in reliance upon such assumption, make available to the Borrower on such
        date a corresponding amount.  If and to the extent that such Bank shall not have so made its Pro Rata Share available to the Agent, such Bank and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount
        together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable at the time to Revolving
        Credit Advances comprising such Revolving Credit Borrowing and (ii) in the case of such Bank, the Federal Funds Rate.  If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank’s Revolving
        Credit Advance as part of such Revolving Credit Borrowing as of the date of such Revolving Credit Borrowing for all purposes.

     

      

    
      23

      
        


    

    (e)          The failure of any Bank to make the Revolving Credit Advance to be made by it as part of any Revolving Credit Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its Revolving Credit Advance on the date
        of such Revolving Credit Borrowing, but no Bank shall be responsible for the failure of any other Bank to make the Revolving Credit Advance to be made by such other Bank on the date of any Revolving Credit 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 and application, given not later than 11:00 A.M. (New York City time) on the third Business Day (or a later day, if acceptable to the relevant
        Issuing Bank in its sole discretion) prior to the date of the proposed issuance of such Letter of Credit, by the Borrower to any Issuing Bank, which shall give to the Agent prompt notice thereof by facsimile or other electronic communication
        (e-mail) (or by telephone notice promptly confirmed by a written, fax or electronic communication (e-mail)).  Each such notice of issuance of a Letter of Credit (a “Notice

            of Issuance and Application for Letter of Credit”) shall be consistent with the requirements of Section 2.01(b) and shall be by telephone, confirmed immediately in writing or by facsimile or other electronic communication (e-mail),
        in substantially the form of Exhibit B-2, specifying therein the requested (A) date of such issuance (which shall be a Business Day), (B) Available Amount of such Letter of Credit, (C) expiration date of such Letter of Credit, (D) name and address
        of the beneficiary of such Letter of Credit, (E) form of such Letter of Credit and (F) currency of such Letter of Credit, if other than Dollars.  If the requested form of such Letter of Credit is acceptable to such Issuing Bank in its sole
        discretion, such Issuing Bank will 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 such issuance; provided that no Issuing Bank shall be obligated to issue any Letter of Credit in any currency other than Dollars, but each Issuing Bank shall be permitted to issue any Letter of Credit in any
        Foreign Currency in its sole discretion if requested by the Borrower; provided further
        that no Issuing Bank shall be obligated to issue any Letter of Credit that is not consistent with the requirements of Section 2.01(b); provided further that no Issuing Bank shall be required to issue any Letter of Credit if the applicable conditions set forth in Article III have not been fulfilled.
        Notwithstanding the foregoing, no Issuing Bank shall issue any Letter of Credit after it has received a notice from the Agent or the Required Banks that a Default or Event of Default has occurred and is continuing, until it receives a subsequent
        notice from the Agent or the Required Banks that such Default or Event of Default has been cured or waived.

    (b)          Letter of Credit Reports.  Each Issuing Bank shall furnish (A) to the Agent on the first Business Day of each week a written report summarizing
        issuance and expiration dates of Letters of Credit issued by such Issuing Bank during the previous week and drawings during such week under all Letters of Credit issued by such Issuing Bank, (B) to the Agent on the first Business Day of each month
        a written report summarizing issuance and expiration dates of Letters of Credit issued by such Issuing Bank during the preceding month and drawings during such month under all Letters of Credit issued by such Issuing Bank and (C) to the Agent on
        the first Business Day of each calendar quarter a written report setting forth the average daily aggregate Available Amount during the preceding calendar quarter of all Letters of Credit issued by such Issuing Bank.  The Agent shall promptly
        deliver each such report to the Banks by the means provided for delivery of Communications pursuant to Section 8.02.

     

      

    
      24

      
        


    

    (c)          Drawing and Reimbursement.  Upon receipt of any notice of drawing under any Letter of Credit, the applicable Issuing Bank shall notify the Borrower
        and the Agent thereof.  If such drawing is paid, the applicable Issuing Bank shall apply cash collateral provided for this purpose with respect to any Defaulting Bank’s, Exercising Bank’s or Non-Extending Bank’s ratable share so long as the
        requirements of Section 2.06(c)(ii) shall continue to be satisfied and the Borrower shall either reimburse the Issuing Bank in an amount equal to the remaining amount of such drawing or the Issuing Bank may make a Letter of Credit Advance, which
        shall be a Base Rate Advance, in the Dollar Equivalent amount of such draft (or such lesser amount after giving effect to any payments or application of cash collateral referred to above).  Upon written demand by any Issuing Bank with an
        outstanding Letter of Credit Advance, with a copy of such demand to the Agent, each Bank absolutely and unconditionally agrees to purchase from such Issuing Bank, and such Issuing Bank shall sell and assign to such Bank, such Bank’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 Agent for the account of such Issuing Bank, by deposit to the 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 Bank.  Promptly after receipt thereof, the Agent shall transfer such funds to such Issuing Bank.  The Borrower hereby
        agrees to each such sale and assignment.  Each Bank agrees to so purchase its Pro Rata Share of an outstanding Letter of Credit Advance, without regard to the minimum and multiples specified in Section 2.02 for the principal amount of Base Rate
        Advances, on (i) the Business Day on which demand therefor is made by the Issuing Bank which made such Advance, provided that notice of such demand is given
        not later than 11:00 A.M. (New York City time) on such Business Day, or (ii) the first Business Day next succeeding such demand if notice of such demand is given after such time, but subject to the amount of the Unused Revolving Credit Commitments
        and the conditions set forth in Section 3.02.  If any Borrowing cannot be made because the conditions set forth in Section 3.02 cannot be satisfied or for any other reason, each Bank’s payment to the Agent for the account of such Issuing Bank
        pursuant to this Section 2.03(c) shall be deemed a Letter of Credit Advance from such Bank in satisfaction of its participation obligation under this Section 2.03.  Upon any such assignment by an Issuing Bank to any Bank of a portion of a Letter of
        Credit Advance, such Issuing Bank represents and warrants to such other Bank that such 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 the Borrower.  If and to the extent that any Bank shall not have so made its Pro Rata Share of the amount of such Letter of Credit Advance available
        to the Agent, such Bank agrees to pay to the Agent forthwith on demand its Pro Rata Share of such amount together with interest thereon, for each day from the date of demand by such Issuing Bank until the date such Bank pays its Pro Rata Share of
        such amount to the Agent, at the Federal Funds Rate for its account or the account of Issuing Bank, as applicable.  If such Bank shall pay to the Agent its Pro Rata Share of such amount for the account of such Issuing Bank on any Business Day, such
        amount so paid in respect of principal shall constitute a Base Rate Advance under the Revolving Credit Facility or a Letter of Credit Advance, as the case may be, made by such Bank on such Business Day for purposes of this Agreement, and the
        outstanding principal amount of the Letter of Credit Advance made by such Issuing Bank shall be reduced on such Business Day by such amount so paid in respect of principal.  

     

      

    
      25

      
        


    

    Each Bank acknowledges and agrees that its obligation to make Base Rate Advance or Letter of Credit
        Advance, as the case may be, pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or Event of Default or reduction or termination of
        the Revolving Credit Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.  The making of Letter of Credit Advances by the Banks pursuant to this paragraph shall not relieve the
        Borrower of any default in the payment thereof.

    (d)          Failure to Make Letter of Credit Advances.  The failure of any Bank to make the Letter of Credit Advance to be made by it on the date specified in
        Section 2.03(c) shall not relieve any other Bank of its obligation hereunder to make its Letter of Credit Advance on such date, but no Bank shall be responsible for the failure of any other Bank to make the Letter of Credit Advance to be made by
        such other Bank on such date.

    (e)          Expiration Date. Each Letter of Credit shall have an expiration date not later than the earlier of (i) one year after the date of the issuance of
        such Letter of Credit and (ii) the date that is three months after the latest Stated Termination Date; provided that 91 days prior to the latest Stated
        Termination Date the Borrower shall grant a first priority perfected security interest in, and deliver to each applicable Issuing Bank, for such Issuing Bank’s sole benefit, an amount in Dollars and in same days funds equal to 105% of the Available
        Amount of all outstanding Letters of Credit issued by such Issuing Bank that have an expiration date later than the latest Stated Termination Date, to be held as cash collateral by such Issuing Bank under the sole control and dominion of such
        Issuing Bank and subject to the terms of this Agreement, which amount (or the appropriate portion thereof) shall be released within three (3) Business Days after notice from the Borrower to the Agent that a Letter of Credit that has an expiration
        date later than the latest Stated Termination Date has been terminated or cancelled or has expired or that there otherwise exists excess cash collateral.  Notwithstanding anything herein to the contrary, provided that the Borrower has cash
        collateralized 105% of the Available Amount of all outstanding Letters of Credit with an expiration date after the latest Stated Termination Date in accordance with this Section 2.03(e), each Bank’s participation in the Letters of Credit shall be
        released as of the latest Stated Termination Date; provided to the extent that any cash collateral by or on behalf of the Borrower is made to an Issuing
        Bank and such cash collateral or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, receiver or any other party, in connection with any proceeding under
        bankruptcy law or otherwise, then (i) to the extent of such recovery, each Bank’s participation or part thereof shall be revived and continued in full force and effect as if such cash collateralization had not occurred, and (ii) each Bank severally
        agrees to pay to the applicable Issuing Bank upon demand its applicable share (without duplication) of any amount so recovered from or repaid by such Issuing Bank, plus interest thereon from the date of such demand to the date such payment is made
        at a rate per annum equal to the Federal Funds Rate from time to time in effect.  The obligations of the Banks and the Issuing Banks under the preceding sentence of this clause (e) shall survive the payment in full of the Obligations and the
        termination of this Agreement.

    Section 2.04          Fees.   Commitment Fees.  (a) The Borrower agrees to
        pay to the Agent for the account of each Bank a commitment fee through the Termination Date for such Bank on the amount of (i) such Bank’s Revolving Credit Commitment at such time minus (ii) without duplication, the sum of (A) the aggregate principal amount of all Revolving Credit Advances and 

     

      

    
      26

      
        


    

    Letter of Credit Advances made by such Bank (other than Letter of Credit Advances made by such Bank in its capacity as an Issuing
        Bank) and outstanding at such time plus (B)  such Bank’s Pro Rata Share of (x) the aggregate Available Amount of all Letters of Credit outstanding
        at such time, (y) the aggregate principal amount of all Letter of Credit Advances made by the Issuing Banks pursuant to Section 2.03(c) and outstanding at such time and (z) cash collateral deposited with respect to any Exercising Bank’s or
        Non-Extending Bank’s ratable share, (1) from the date of this Agreement in the case of each Bank listed on the signature pages hereof or (2) from the effective date specified in the Assignment and Acceptance pursuant to which it became a Bank,
        payable quarterly in arrears (within three (3) Business Days after receipt from the Agent of an invoice therefor) for each period ending on the last day of each March, June, September and December hereafter, commencing March 31, 2019, and on the
        Termination Date for each Bank, at a rate per annum equal to the Applicable Commitment Fee Rate in effect from time to time (the “Commitment Fee”).

    (b)          Letter of Credit Fees, Etc.   (i) The Borrower shall pay to the Agent for the account of each Bank (including, without duplication, the applicable
        Issuing Bank) a commission, payable in arrears quarterly (within three Business Days after receipt from the Agent of an invoice therefor) for each period ending on the last day of each March, June, September and December, commencing March 31, 2019
        until the applicable expiration date for such Letter of Credit and, if applicable, on the Termination Date for each Bank, on such Bank’s Pro Rata Share of the average daily aggregate Available Amount during such quarter of all Letters of Credit
        then outstanding at a rate equal to the Applicable Margin on Eurodollar Rate Advances in effect from time to time; provided, however, that with respect to Performance Letters of Credit and Commercial Letters of Credit such commission shall be equal to 50% of such Applicable Margin from time to time.

    
      	
              (ii)

            	
              The Borrower shall pay to each Issuing Bank, for its own account, (A) an
                  issuance fee for each Letter of Credit issued by such Issuing Bank in an amount as the Borrower and such Issuing Bank shall agree and (B) such other commissions, fronting fees, transfer fees and other fees and charges in connection with
                  the issuance or administration of each Letter of Credit as the Borrower and such Issuing Bank shall agree (within three Business Days after receipt from the Issuing Bank of an invoice therefor).

            


    

    (c)          Other Fees.  The Borrower agrees to pay to the Agent, the Joint Lead Arrangers, and the Banks such other fees as may be separately agreed to in
        writing.

    (d)          Defaulting Bank Adjustments.  Anything herein to the contrary notwithstanding, during such period as a Bank is a Defaulting Bank, such Defaulting
        Bank will not be entitled to any fees accruing during such period pursuant to Section 2.04(a) and Section 2.04(b) (without prejudice to the rights of the Non-Defaulting Banks in respect of such fees), provided that (i) to the extent that all or a portion of the Defaulting Bank Exposure of such Defaulting Bank is reallocated to the Non-Defaulting Banks pursuant to Section 2.24(a), such fees that
        would have accrued for the benefit of such Defaulting Bank will instead accrue for the benefit of and be payable to such Non-Defaulting Banks, pro rata in accordance with their respective Revolving Credit Commitments, and (ii) to the extent that all or any portion of such Defaulting Bank Exposure cannot be
        so reallocated, such fees will instead accrue for the benefit of and be payable to the Issuing Banks and the Swingline Bank, as applicable (and the pro rata payment provisions of Section 2.14 will automatically be deemed adjusted to reflect the provisions of this Section).

    Section 2.05          Reduction of Commitments.  The Borrower shall have the right, upon at least three (3) Business Days’ notice to the Agent, to terminate in whole
        or reduce ratably in part the Unused Revolving Credit Commitments; provided that each partial reduction shall be in the minimum aggregate amount of
        $10,000,000 and in an integral multiple of $5,000,000; provided further
        that no such termination or reduction shall be made pursuant to this Section 2.05, unless after giving effect thereto, the Revolving Credit Facility equals or exceeds the aggregate Letter of Credit Commitments of the Issuing Banks.  The Borrower
        shall have the right, upon at least three (3) Business Days’ notice to the Agent and an Issuing Bank to terminate in whole or reduce the Letter of Credit Commitment of such Issuing Bank; provided that each partial reduction shall be in the minimum amount of $10,000,000 and in an integral multiple of $5,000,000; provided
        further that no termination or reduction of the Letter of Credit Commitment of any Issuing Bank shall be made pursuant to this Section 2.05, unless after giving effect thereto, the Letter of Credit Commitment of such Issuing Bank equals or exceeds

        collateral deposited with such Issuing Bank with respect to any Exercising Bank or Non-Extending Bank.  A notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other
        credit facilities, and such notice may be revoked by the Borrower (by notice to the Agent on or prior to the specified effective date) if such condition is not satisfied.  Any termination or reduction of any of the Commitments shall be permanent.

        Credit Advance made by each of them.

    
      	
              (ii)

            	
              The Obligations of the Borrower under this Agreement and any other
                  agreement or instrument, in each case relating to any Letter of Credit, shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement and such other agreement or instrument
                  under all circumstances, including, without limitation, the following circumstances (it being understood that any such payment by the Borrower is without prejudice to, and does not constitute a waiver of, any rights the Borrower might
                  have or might acquire against any Issuing Bank as a result of the payment by any Issuing Bank of any draft or the reimbursement by the Borrower thereof):

            


    

    
      	
              (A)

                  Credit, any Notice of Issuance and Application for Letter of Credit or any other agreement or instrument relating thereto (all of the foregoing being, collectively, the “L/C Related Documents”);

            


    

    
      	
              (B)

            	
              any change in the time, manner or place of payment of, or in any other
                  term of, all or any of the Obligations of the Borrower in respect of any L/C Related Document or any other amendment or waiver of or any consent to departure from all or any of the L/C Related Documents;

            


    

    
      	
              (C)

            	
              the existence of any claim, set-off, defense or other right that the
                  Borrower may have at any time against any beneficiary or any transferee of a Letter of Credit (or any Persons for which any such beneficiary or any such transferee may be acting), any Issuing Bank or any other Person, whether in
                  connection with the transactions contemplated by the L/C Related Documents or any unrelated transaction;

            


    

    
      	
              (D)

            	
              any statement or any other document presented under a Letter of Credit
                  proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

              payment by any Issuing Bank under a Letter of Credit against presentation
                  of a draft or certificate that does not strictly comply with the terms of such Letter of Credit;

            


    

    
      	
              (F)

            	
              any exchange, release or non-perfection of any collateral, or any release
                  or amendment or waiver of or consent to departure from any guarantee, for all or any of the Obligations of the Borrower in respect of the L/C Related Documents; or

            


    

    
      	
              (G)

            	
              any other circumstance or happening whatsoever, whether or not similar to
                  any of the foregoing, including, without limitation, any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower or a guarantor.

    (c)          Required Payment and Cash Collateral.

    
      	
              (i)

            	
              If on any date the sum of the aggregate Available Amount of all Letters of
                  Credit outstanding on such date plus the aggregate principal amount of Revolving Credit Advances, Letter of Credit Advances and Swingline Advances outstanding on such date exceeds the Revolving Credit Facility on such date, the Borrower
                  shall, within three (3) Business Days thereafter, (A) prepay Swingline Advances, Letter of Credit Advances and Revolving Credit Advances in an aggregate principal amount sufficient to reduce the sum of the Available Amount of all Letters
                  of Credit outstanding on such date plus the aggregate principal amount of Revolving Credit Advances, Letter of Credit Advances and Swingline Advances outstanding on such date to be less than or equal to the Revolving Credit Facility on
                  such date or (B) if no Revolving Credit Advances, Letter of Credit Advances or Swingline Advances are outstanding at such time or prepayment pursuant to clause (A) of this sentence does not result in the sum of the Available Amount of all
                  Letters of Credit outstanding on such date plus the aggregate principal amount of Revolving Credit Advances, Letter of Credit Advances and Swingline Advances outstanding on such date being less than or equal to the Revolving Credit
                  Facility on such date, pay to the Agent in same day funds at the Agent’s office, for deposit in the Cash Collateral Account, an amount equal to such excess less the principal amount of Advances so prepaid, which amount shall be released
                  within three (3) Business Days after notice from the Borrower to the Agent that the sum of the aggregate Available Amount of all Letters of Credit plus the aggregate principal amount of Revolving Credit Advances, Letter of Credit Advances
                  and Swingline Advances outstanding no longer exceeds the Revolving Credit Facility.  If on any date the Available Amount of all Letters of Credit outstanding on such date issued by any Issuing Bank plus the aggregate principal amount of
                  all Letter of Credit Advances outstanding on such date relating to any Letter of Credit issued by such Issuing Bank plus the cash collateral deposited with such Issuing Bank with respect to any Exercising Bank or Non-Extending Bank
                  exceeds the Letter of Credit Commitment of such Issuing Bank on such date, the Borrower shall, within three (3) Business Days thereafter, pay to the Agent in same day funds at the Agent’s office, for deposit in the Cash Collateral
                  Account, an amount equal to such excess which amount shall be released within three (3) Business Days after notice from the Borrower to the Agent that the sum of the Available Amount of all Letters of Credit issued by such Issuing Bank
                  plus the aggregate principal amount of all Letter of Credit Advances outstanding made by such Issuing Bank plus the cash collateral deposited with such Issuing Bank with respect to any Exercising Bank or Non-Extending Bank no longer
                  exceeds the Letter of Credit Commitment of such Issuing Bank.

            


    

    
      	
              (ii)

            	
              If any Bank becomes, and during the period it remains, a Defaulting Bank
                  or a Potential Defaulting Bank, if any Letter of Credit or Swingline Advance is at the time outstanding, any Issuing Bank and the Swingline Bank, as the case may be, may (except, in the case of a Defaulting Bank, to the extent the
                  Commitments have been fully reallocated pursuant to Section 2.24(a)), by notice to the Borrower and such Defaulting Bank or Potential Defaulting Bank through the Agent, require the Borrower to pay to the Agent in same day funds at the
                  Agent’s office, for deposit in the Cash Collateral Account, an amount equal to the obligations of the Borrower to the Issuing Banks and the Swingline Bank in respect of such Letters of Credit or Swingline Advances in amount at least equal
                  to 100% of the aggregate amount of the unreallocated obligations (contingent or otherwise) of such Defaulting Bank or such Potential Defaulting Bank to be applied pro rata in respect thereof, or to make other arrangements satisfactory to the Agent, and to the Issuing Banks and the
                  Swingline Bank, as the case may be, in their sole discretion to protect them against the risk of non-payment by such Defaulting Bank or Potential Defaulting Bank.

        amount shall be paid in full, at the following rates per annum:

        quarterly in arrears on the last day of each March, June, September and December and on the date such Base Rate Advance shall be Converted or paid in full; provided
        that any amount of principal of a Base Rate Advance which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest, payable on demand, from the date on which such amount is due until such amount is paid in
        full, at a rate per annum equal at all times to the sum of the rate otherwise payable thereon plus 2%.

    (b)          During such periods as a Revolving Credit Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during each Interest Period for such Advance to the sum of the Eurodollar Rate for such Interest Period plus the
        Applicable Margin in effect from time to time, payable on the last day of such Interest Period and, if such Interest Period has a duration of more than three months, on each day that occurs during such Interest Period every three months from the

        each March, June, September and December and on the date such Swingline Advance shall be paid in full; provided that any amount of principal of a Swingline
        Advance which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest, payable on demand, from the date on which such amount is due until such amount is paid in full, at a rate per annum equal at all
        times to the sum of the rate otherwise payable thereon plus 2%.

    (d)          Upon the occurrence and during the continuance of an Event of Default under Section 6.01(a) or Section 6.01(e), the Borrower shall pay simple interest, to the fullest extent permitted by law, on the amount of any interest, fee or other
        amount (other than principal of Advances which is covered by Sections 2.07(a), 2.07(b) and 2.07(c)) payable hereunder that is not paid when due, from the date such amount shall be due until such amount shall be paid in full, payable in arrears on
        the date such amount shall be paid in full and on demand, at a rate per annum equal at all times to the sum of the rate of interest in effect from time to time for Base Rate Advances plus 2% per annum.

    Section 2.08          Additional Interest on Eurodollar Rate Advances.  The Borrower shall pay to each Bank, so long as such Bank shall be required under regulations
        of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Bank, from the
        date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (a) the Eurodollar Rate for the Interest Period then in effect for such Eurodollar Rate
        Advance from (b) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Bank for such Interest Period.  Such additional interest shall be determined by such Bank and
        notified to the Borrower through the Agent.  Payments under this Section 2.08 shall be made within 15 days from the date such Bank makes written demand therefor (or, if later, on the date on which interest is payable on the relevant Eurodollar Rate
        Advance).

    Section 2.09          Interest Rate Determination.   (a) The Agent shall give prompt notice to the Borrower and the Banks of the applicable interest rate determined by
        the Agent for purposes of Section 2.07(b).

    (b)          If the Agent is unable to determine the Eurodollar Rate for any Eurodollar Rate Advances:

    
      	
              (i)

            	
              the Agent shall forthwith notify the Borrower and the Banks that the
                  interest rate cannot be determined for such Eurodollar Rate Advances,

            


    

    
      	
              (ii)

            	
              such Eurodollar Rate Advance will automatically, on the last day of the
                  then existing Interest Period therefor, Convert into a Base Rate Advance (or if such Advance is then a Base Rate Advance, will continue as a Base Rate Advance), and

            


    

    
      	
              (iii)

            	
              the obligation of the Banks to make Eurodollar Rate Advances or to Convert
                  Revolving Credit Advances into Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist.

            


    

    (c)          If, due to a major disruption in the interbank funding market with respect to any Eurodollar Rate Advances, the Required Banks notify the Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect
        the cost to such Required Banks of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Agent shall forthwith so notify the Borrower and the Banks, whereupon

    
      	
              (i)

            	
              each 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 Banks to make, or to Convert Advances into,
                  Eurodollar Rate Advances shall be suspended until the Agent shall notify the Borrower and the Banks that the circumstances causing such suspension no longer exist.

            


    

    (d)          If the Borrower shall fail to select the duration of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01, the Agent will forthwith so
        notify the Borrower and the Banks and such Revolving Credit Advances will automatically, on the last day of the then existing Interest Period therefor, Convert into Base Rate Advances (or if such Advances are then Base Rate Advances, will continue
        as Base Rate Advances).

     

      

    
      32

      
        


    

    (e)          On the date on which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $10,000,000, such Advances shall automatically Convert
        into Base Rate Advances, and on and after such date the right of the Borrower to Convert such Advances into Eurodollar Rate Advances shall terminate.

    (f)          Upon the occurrence and during the continuance of any Event of Default under Section 6.01(a) or Section 6.01(e), (i) each 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 Banks to make or continue, or to Convert Advances into, Eurodollar Rate Advances shall be suspended.

    (g)          Notwithstanding anything
        to the contrary in this Agreement or any other Loan Documents, if the Administrative Agent determines in good faith (which determination shall be conclusive absent manifest error), or the Borrower or the Required Banks notify the Administrative
        Agent (with, in the case of the Required Banks, a copy to the Borrower) that the Borrower or the Required Banks, as applicable have determined, that:

    (i)            adequate and reasonable means do not exist for ascertaining LIBOR
        for any requested Interest Period, including, without limitation, because the Eurodollar Rate is not available or published on a current basis and such circumstances are unlikely to be temporary;

    (ii)           the supervisor for the administrator of the Eurodollar Rate or a
        governmental authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which LIBOR or the Eurodollar Rate shall no longer be made available, or used for determining the interest rate
        of loans (such specific date, the “Scheduled Unavailability Date”); or

    (iii)          syndicated loans in the U.S. market denominated in Dollars being executed at the time, or that include language similar to that contained in this Section 2.09(g), are being generally executed or amended, as applicable, to
        incorporate or adopt, as applicable, a new benchmark interest rate to replace LIBOR,

    then, after such determination by the Administrative Agent or receipt by the Administrative Agent of such notice, as
        applicable, the Administrative Agent and the Borrower may amend this Agreement to replace the Eurodollar Rate with an alternate benchmark rate (including any mathematical or other adjustments to the benchmark (if any) incorporated therein), giving
        due consideration to any evolving or then existing convention for similar credit facilities in the U.S. market denominated in Dollars for such alternative benchmarks (any such proposed rate, a “LIBOR Successor Rate”), together with any proposed LIBOR Successor Rate Conforming 

     

      

    
      33

      
        


    

    Changes and, notwithstanding anything to the contrary in Section 8.01, any such amendment shall become effective at 5:00
        p.m. (New York time) on the fifth Business Day after the Administrative Agent shall have posted such proposed amendment to all Banks and the Borrower unless, prior to such time, Banks comprising the Required Banks have delivered to the
        Administrative Agent notice that such Required Banks do not accept such amendment. 

    If no LIBOR Successor Rate has been determined and the circumstances under clause (i) above exist,
        the obligation of the Banks to make or maintain Eurodollar Rate Advances shall be suspended, (to the extent of the affected Eurodollar Rate Advances or Interest Periods).  Upon receipt of such notice, the Borrower may revoke any pending request for
        a Eurodollar Rate Advance of, conversion to or continuation of Eurodollar Rate Advances (to the extent of the affected Eurodollar Rate Advances or Interest Periods) or, failing that, will be deemed to have converted such request into a request for
        a Borrowing of Base Rate Advances in the amount specified therein.

    Section 2.10          Optional Prepayments.  The Borrower may, upon notice given to the Agent before 11:00 A.M. (New York City time) on the first Business Day prior to
        the date of prepayment in the case of Base Rate Advances or upon at least three (3) Business Days’ notice to the Agent in the case of Eurodollar Rate Advances, in each case stating the proposed date (which shall be a Business Day) and aggregate
        principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding principal amounts of the Revolving Credit Advances comprising part of the same Borrowing in whole or ratably in part, together with accrued
        interest to the date of such prepayment on the principal amount prepaid; provided, however, that (x) each partial prepayment shall be in an aggregate principal amount not less than $10,000,000 in the case of Eurodollar Rate Advances and $5,000,000 in the case of Base Rate Advances and in integral multiples
        of $1,000,000, and after giving effect thereto no Borrowing then outstanding shall have a principal amount of less than $5,000,000; and (y) in the case of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to
        reimburse the Banks in respect thereof pursuant to Section 8.04(b).  The Borrower may, upon notice given to the Swingline Bank before 1:00 P.M. (New York City time) on the date of prepayment stating the proposed date (which shall be a Business Day)
        and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding principal amounts of the Swingline Advances in whole or ratably in part, together with accrued interest to the date of such
        prepayment on the principal amount prepaid; provided, however,
        that each partial prepayment shall be in an aggregate principal amount not less than $1,000,000 and in integral multiples of $1,000,000.  If a notice of prepayment is given pursuant to this Section 2.10 in connection with a conditional notice of
        termination of the Commitments as contemplated by Section 2.05, such notice of prepayment may be revoked (and no prepayment shall be required pursuant thereto) if such notice of termination is revoked in accordance with Section 2.05.

    Section 2.11          Payments and Computations.   (a) All payments to be made by the Borrower shall be made without condition or deduction for any counterclaim,
        defense, recoupment or setoff.  The Borrower shall make each payment hereunder and under the Notes not later than 11:00 A.M. (New York City time) on the day when due in Dollars to the Agent (except that payments under Section 2.08 shall be paid
        directly to the Bank entitled thereto) at 1615 Brett Road OPS III, New Castle, Delaware 19720, in same day funds.  The Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, 

     

      

    
      34

      
        


    

    interest, Commitment Fees or Letter of Credit fees ratably (except amounts payable pursuant to Section 2.12, Section 2.13 or
        Section 2.17 and except that (i) any Bank may receive less than its Pro Rata Share of interest to the extent Section 8.06 is applicable to it, (ii) if the Stated Termination Date for all Banks is not the same, then principal payments due pursuant
        to Section 2.06(a) in respect of the Stated Termination Date for any Bank (but not in respect of payments due before the relevant Stated Termination Date as contemplated by Section 2.06(a)) shall be distributed ratably among all Banks having that
        same Stated Termination Date (and not to those Banks with a Stated Termination Date occurring later), and (iii) if, in respect of any Change in Control, not all Banks are Exercising Banks, then payments due from the Borrower pursuant to
        Section 2.23 shall be distributed ratably among all such Exercising Banks (and not to those Banks that are not Exercising Banks)) to the Banks for the account of their respective Applicable Lending Offices, and like funds relating to the payment of
        any other amount payable to any Bank to such Bank 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 Acceptance and recording of the
        information contained therein in the Register pursuant to Section 8.08(c), from and after the effective date specified in such Assignment and Acceptance, the Agent shall make all payments hereunder and under the Notes in respect of the interest
        assigned thereby to the Bank assignee thereunder, and the parties to such Assignment and Acceptance shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.  At the time of each
        payment of any principal of or interest on any Borrowing to the Agent, the Borrower shall notify the Agent of the Borrowing to which such payment shall apply.  In the absence of such notice the Agent may specify the Borrowing to which such payment
        shall apply.

    (b)          All computations of interest based on the Base Rate (except during such times as the Base Rate is determined pursuant to clause (b) or clause (c) of the definition thereof), of Commitment Fees and of Letter of Credit fees shall be made by
        the 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, the Federal Funds Rate or, during such times as the Base Rate is determined pursuant to clause (b) or clause (c)
        of the definition thereof, the Base Rate shall be made by the Agent, and all computations of interest pursuant to Section 2.08 shall be made by a Bank, 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 or fees are payable.  Each determination by the Agent (or in the case of Section 2.08, by a Bank) of an interest rate hereunder shall be conclusive and binding
        for all purposes, absent manifest error.

    (c)          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, Commitment Fees and Letter of Credit fees, as the case may be; provided, however, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next
        preceding Business Day.

    (d)          Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such
        payment in full to the

     

      

    
      35

      
        


    

     Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on
        such due date an amount equal to the amount then due such Bank.  If and to the extent that the Borrower shall not have so made such payment in full to the Agent, each Bank shall repay to the Agent forthwith on demand such amount distributed to such
        Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent, at the Federal Funds Rate.

    Section 2.12          Increased Costs and Capital Requirements.   (a) If, due to either (i) the introduction of or any change (other than any change by way of
        imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation by any governmental authority charged with the interpretation or administration thereof after
        the date of this Agreement or (ii) the compliance with any guideline or request from any central bank or other governmental authority that would be complied with generally by similarly situated banks acting reasonably (whether or not having the
        force of law and for the avoidance of doubt, including any changes resulting from requests, rules, guidelines or directives concerning capital adequacy or liquidity issued after the date hereof in connection with the Dodd-Frank Wall Street Reform
        and Consumer Protection Act or promulgated after the date hereof by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities,
        in each case pursuant to Basel III) made or issued after the date of this Agreement, there shall be any increase in the cost to any Bank of agreeing to make or making, funding or maintaining any Eurodollar Rate Advance or of agreeing to issue or of
        issuing or maintaining or participating in Letters of Credit or of agreeing to make or of making or maintaining Letter of Credit Advances (excluding, for purposes of this Section 2.12, any such increased costs resulting from (x) Taxes or Other
        Taxes (as to which Section 2.13 shall govern) and (y) changes in the rate of, or the imposition of, any Excluded Tax) or any reduction in the amount of any sum receivable by such Bank hereunder (whether of principal, interest or any other amount),
        in each case, by an amount deemed by such Bank to be material, then the Borrower shall from time to time, within 15 days after demand by such Bank (with a copy of such demand to the Agent), pay to the Agent for the account of such Bank additional
        amounts sufficient to compensate such Bank for such increased cost or such reduction suffered, as the case may be; provided, however, that the Borrower shall not be required to pay to such Bank any portion of such additional amounts that are incurred more than 90 days prior to any such demand (except that, if
        the event giving rise to such increased costs or reductions is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof).

    (b)          If following the introduction of or any change in any applicable law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law, and for the avoidance of doubt,
        including any changes resulting from requests, rules, guidelines or directives concerning capital adequacy or liquidity issued after the date hereof in connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act or promulgated
        after the date hereof by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III) made or
        issued after the date of this Agreement any Bank determines that compliance by such Bank with any such law or regulation or guideline or request regarding capital adequacy or liquidity requirements has or would have the effect of reducing the rate
        of return on such Bank’s capital or the capital of any Person controlling such Bank as a consequence of such Bank’s commitment to lend or to issue or participate in Letters of Credit hereunder or 

     

      

    
      36

      
        


    

    the issuance or maintenance of or participation in Letters of Credit to a level below that which such Bank or
        such Person could have achieved but for such introduction or change in law, regulation, guideline or request (taking into consideration such Bank’s or such Person’s policies and the policies of such Bank or such Person with respect to capital
        adequacy) by an amount deemed by such Bank to be material, then, within 15 days after demand by such Bank (with a copy of such demand to the Agent), the Borrower shall pay to the Agent for the account of such Bank, from time to time as specified by
        such Bank, such additional amounts sufficient to compensate such Bank or such Person for any such reduction suffered; provided, however, that the Borrower shall not be required to pay to such Bank any portion of such additional amounts that are incurred more than 90 days prior to
        any such demand (except that, if the event giving rise to such reductions is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof).

    (c)          Each Bank shall make reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to select a jurisdiction for its Applicable Lending Office or change the jurisdiction of its Applicable Lending Office,
        as the case may be, so as to avoid the imposition of any increased costs under this Section 2.12 or to eliminate the amount of any such increased cost which may thereafter accrue; provided that no such selection or change of the jurisdiction for its Applicable Lending Office shall be made if, in the reasonable judgment of such Bank, such selection or change would be materially disadvantageous
        to such Bank.

    (d)          A certificate of a Bank setting forth in reasonable detail the amounts necessary to compensate such Bank as specified in clause (a) or (b) of this Section 2.12 shall be submitted to the Borrower and the Agent by such Bank and shall be
        conclusive and binding for all purposes, absent manifest error.  Notwithstanding the foregoing, no Bank shall be entitled to seek compensation pursuant to this Section 2.12 unless the certificate referred to in the preceding sentence shall (i)
        state that it is the general practice of such Bank at the time to seek compensation under similar circumstances from other similarly situated borrowers (to the extent such Bank has the right under such similar credit facilities to do so) and (ii)
        set forth in reasonable detail the manner in which such amount or amounts were determined.

    (e)          For purposes of this Agreement and to the extent permitted by applicable laws, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives in connection therewith and (ii) all
        requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case
        pursuant to Basel III, are, in each case, deemed to have gone into effect and been adopted after the date of this Agreement.

    Section 2.13          Taxes.   (a) Any and all payments by the Borrower hereunder or under the Notes shall be made, in accordance with Section 2.11, free and clear of
        and without deduction or withholding for any and all present or future taxes, levies, imposts, deductions, charges and withholdings, and all liabilities with respect thereto, excluding, in the case of each Bank and the Agent, (i) taxes imposed on
        its overall net income (including branch profits), and franchise taxes imposed on or measured by net income, in each case, (A) imposed by the jurisdiction under the laws of which

      

     

      

    
      37

      
        


    

    
     such Bank or the Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Bank, taxes
        imposed on its overall net income (including branch profits), and franchise taxes imposed on or measured by net income, by the jurisdiction of such Bank’s Applicable Lending Office or principal executive office or any political subdivision thereof
        or (B) that are Other Connection Taxes, (ii) any U.S. Federal withholding taxes resulting from any law in effect on the date a Bank becomes a party to this Agreement (or designates a new Applicable Lending Office), except to the extent that such
        Bank (or its assignor, if any) was entitled, at the time of designation of a new Applicable Lending Office (or assignment), to receive additional amounts from the Borrower with respect to such withholding taxes pursuant to this Section 2.13(a),
        (iii) any withholding tax resulting from a Bank’s failure to comply with Section 2.13(f), (iv) any U.S. Federal withholding Taxes imposed under FATCA, and (v) taxes imposed as a result of a present or former connection between the recipient and the
        taxing jurisdiction or any political subdivision thereof (other than a connection arising solely from such recipient entering into, delivering, performing its obligations under, enforcing, or receiving payments hereunder) (subsections (i) through
        (v) referred to as the “Excluded Taxes” and all other taxes, levies, imposts, deductions, charges, withholdings and liabilities other than the
        Excluded Taxes being hereinafter referred to as “Taxes”), except as may otherwise be required by law.  If the Borrower shall be required by law to
        deduct or withhold any Taxes from or in respect of any sum payable hereunder or under any Note to any Bank or the Agent, (i) the sum payable shall be increased by such amount (an “Additional Amount”) as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13) or withholdings such Bank or the
        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 and (iii) the Borrower shall pay the full amount deducted to the relevant taxation
        authority or other authority in accordance with applicable law.  Any such payment by the Borrower shall be made in the name of the relevant Bank or the Agent (as the case may be).

    (b)          In addition, the Borrower agrees to timely pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under the Notes or from the
        execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or any of the Notes, except any such Taxes that are Other Connection Taxes imposed with respect to an assignment (other than an assignment made
        pursuant to Section 2.17) (hereinafter referred to as “Other Taxes”).

    (c)          The Borrower will indemnify each Bank and the Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.13) imposed on
        or paid by such Bank or the Agent (as the case may be) or required to be withheld or deducted from a payment to such Bank or the Agent and, in each case, any liability (including penalties, interest and reasonable expenses) arising therefrom or
        with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted.  Payments under any indemnification provided for in this Section 2.13(c) shall be made within 30 days from the date such Bank or the Agent (as the
        case may be) makes written demand therefor describing such Taxes or Other Taxes in reasonable detail.

     

      

    
      38

      
        


    

    (d)          If the Agent or a Bank reasonably determines that it has finally and irrevocably received a refund in respect of any Taxes or Other Taxes as to which it has been indemnified by the Borrower, or with respect to which the Borrower has paid
        Additional Amounts, pursuant to this Section 2.13, it shall within 30 days from the date of such receipt pay over such refund to the Borrower (but only to the extent such refund is attributable, as reasonably determined by the Agent or such Bank,
        to such indemnity payments made, or Additional Amounts paid, by the Borrower under this Section 2.13 with respect to the Taxes or Other Taxes giving rise to such refund), net of all reasonable out-of-pocket expenses of the Agent or Bank and without
        interest (other than interest paid by the relevant taxation authority with respect to such refund); provided, however, that the Borrower, upon the request of the Agent or such Bank, agrees to repay the amount paid over to the Borrower (plus penalties, interest or other charges, if any, imposed by the
        relevant taxation authority in respect of such repayment) to the Agent or such Bank in the event the Agent or such Bank is required to repay such refund to the applicable taxation authority.  Notwithstanding anything to the contrary in this
        Section 2.13(d), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 2.13(d) the payment of which would place the indemnified party in a less favorable net after-Tax position than
        the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had
        never been paid.  Nothing contained in this Section 2.13(d) shall interfere with the right of the Agent or any Bank to arrange its tax affairs in whatever manner it determines appropriate or oblige the Agent or any Bank to claim any tax credit or
        tax refund or to disclose any information relating to its tax affairs or any computations in respect thereof or require the Agent or any Bank to do anything that would prejudice its ability to benefit from any other tax relief to which it may be
        entitled.

    (e)          Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof (or other evidence of
        payment reasonably satisfactory to the Agent).

    (f)          Each Bank (i) on or prior to the date of the Initial Extension of Credit in the case of each Bank listed on the signature pages hereof, (ii) on the date of the Assignment and Acceptance pursuant to which it becomes a Bank, (iii) on or
        before the date, if any, it changes its Applicable Lending Office, and (iv) from time to time thereafter if reasonably requested in writing by the Borrower or the Agent or promptly upon the obsolescence or invalidity of any form previously
        delivered by such Bank (but only so long as such Bank remains lawfully able to do so), shall provide the Agent and the Borrower with (A) in the case of a Bank organized under the laws of the United States, a State thereof or the District of
        Columbia (in such number of copies reasonably requested by the Agent and the Borrower), Internal Revenue Service Forms W-9 certifying that such Bank is exempt from U.S. Federal backup withholding tax and (B) in the case of a Bank organized under
        the laws of a jurisdiction outside the United States, a State thereof or the District of Columbia, two original Internal Revenue Service Forms W-8BEN or W-8ECI (or, in the case of a Bank that is entitled to claim exemption from withholding of
        United States Federal income tax under Section 871(h) or 881(c) of the Code, (1) a certificate representing that such Bank is not a “bank” for purposes of Section 881(c) of the Code, is not a 10-percent shareholder (within the meaning of
        Section 871(h)(3)(B) of the Code) of the Borrower and is not a controlled foreign corporation related to the Borrower (within the meaning

     

      

    
      39

      
        


    

     of Section 864(d)(4) of the Code) and (2) Internal Revenue Service Form W-8BEN), as appropriate, or any
        successor or other form prescribed by the Internal Revenue Service, properly completed and duly executed by such Bank, certifying that such Bank is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to
        this Agreement or the Notes (or, in the case of a Bank providing the certificate described in clause (1), certifying that such Bank is a foreign corporation, partnership, estate or trust).  If the forms provided by a Bank at the time such Bank
        first becomes a party to this Agreement indicate or require a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes for purposes of this Section 2.13 unless and until
        such Bank provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such forms; provided, however, that if, at the effective date of the Assignment and
        Acceptance pursuant to which a Bank becomes a party to this Agreement (or the date, if any, a Bank changes its Applicable Lending Office), the Bank assignor (or such Bank) 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, subject to the provisions of this subsection (f)) United States withholding tax, if any, applicable with respect to the Bank assignor (or such Bank) on such date.  For purposes of this Section 2.13(f), the terms “United States” and “United States person” shall have the meanings
        specified in Section 7701 of the Code.

    (g)          For any period with respect to which the Agent, a Bank or an Issuing Bank has failed to provide the Borrower with the appropriate form described in Section 2.13(f) (other than if such failure is due to a change in law, or in the
        interpretation or application thereof by any governmental authority charged with the interpretation or application thereof, occurring after the date on which a form originally was required to be provided or if such form otherwise is not required),
        such Bank shall not be entitled to indemnification or payment of an Additional Amount under Sections 2.13(a) or 2.13(c) with respect to Taxes imposed by the United States to the extent such United States Taxes exceed the United States Taxes that
        would have been imposed had such form been provided; provided, however,
        that should a Bank become subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Bank shall reasonably request to assist such Bank to recover such Taxes.

    (h)          Any Bank claiming any indemnity payment or Additional Amounts payable pursuant to this Section 2.13 shall use commercially reasonable efforts (consistent with its generally applicable internal policy and legal and regulatory restrictions)
        to file any certificate or document reasonably requested in writing by the Borrower or to designate a different Applicable Lending Office following the reasonable request in writing of the Borrower if the making of such a filing or change would
        avoid the need for or reduce the amount of any such indemnity payment or Additional Amounts that may thereafter accrue and would not, in the sole determination of such Bank, require the disclosure of information that such Bank reasonably considers
        confidential, or be otherwise materially disadvantageous to such Bank.

    (i)          If a payment made to the Agent, any Bank or any Issuing Bank under this Agreement would be subject to U.S. Federal withholding tax imposed by FATCA if the Agent, such Bank or such Issuiig Bank fails to comply with the applicable reporting
        requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), the Agent, 

     

      

    
      40

      
        


    

    such Bank or such Issuing Bank shall deliver to the Borrower or the Agent, at the time or times prescribed by
        law and at such time or times reasonably requested by the Borrower or the Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably
        requested by the Borrower or the Agent as may be necessary for the Borrower or the Agent to comply with its obligations under FATCA, to determine that the Agent, such Bank or such Issuing Bank has complied with its obligations under FATCA or to
        determine the amount to deduct and withhold from any such payments.  Solely for purposes of this Section 2.13(i), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

    Section 2.14          Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or
        otherwise) on account of the principal of or interest on the Advances owing to it (except amounts payable pursuant to Sections 2.08, 2.12, 2.13, 2.17 or 8.08 and except that (i) any Bank may receive less than its Pro Rata Share of interest to the
        extent Section 8.06 is applicable to it, (ii) if the Stated Termination Date for all Banks is not the same, then principal payments due pursuant to Section 2.06(a) in respect of the Stated Termination Date for any Bank (but not in respect of
        payments due before the relevant Stated Termination Date as contemplated by Section 2.06(a)) shall be distributed ratably among all Banks having that same Stated Termination Date (and not to those Banks with a Stated Termination Date occurring
        later), and (iii) if, in respect of any Change in Control, not all Banks are Exercising Banks, then payments due from the Borrower pursuant to Section 2.23 shall be distributed ratably among all such Exercising Banks (and not to those Banks that
        are not Exercising Banks)) in excess of its Pro Rata Share of payments on account of the principal of or interest on the Advances obtained by all the Banks, such Bank shall forthwith purchase from the other Banks such participations in the Advances
        owing to them as shall be necessary to cause such purchasing Bank 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 Bank, such purchase from each Bank shall be rescinded and such Bank shall
        repay to the purchasing Bank the purchase price to the extent of such Bank’s ratable share (according to the proportion of (A) the amount of the participation purchased from such Bank as a result of such excess payment to (B) the total amount of
        such excess payment) of such recovery together with an amount equal to such Bank’s ratable share (according to the proportion of (A) the amount of such Bank’s required repayment to (B) the total amount so recovered from the purchasing Bank) of any
        interest or other amount paid or payable by the purchasing Bank in respect of the total amount so recovered.  The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.14 may, to the fullest extent
        permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation.

    Section 2.15          Illegality.  Notwithstanding any other provision of this Agreement, if any Bank (“Affected Bank”) shall notify the Borrower and the Agent that the introduction of or any change in any law or regulation after the date of this Agreement makes it unlawful, or any central bank or other governmental
        authority asserts that it is unlawful, for the Affected Bank, or its Eurodollar Lending Office, to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (a) the obligation of
        the Affected Bank to make, or to

     

      

    
      41

      
        


    

     Convert Advances into, Eurodollar Rate Advances shall forthwith be suspended (and any request by the Borrower for a Borrowing
        comprised of Eurodollar Rate Advances shall, as to each Affected Bank, be deemed a request for a Base Rate Advance to be made on the same day as the Eurodollar Rate Advances of the Banks that are not Affected Banks and such Base Rate Advance shall
        be considered as part of such Borrowing) until the Affected Bank shall notify the Borrower, the other Banks and the Agent that the circumstances causing such suspension no longer exist and (b) on the last day of the then applicable Interest Period
        (or such earlier date required by law as specified in such notice from such Affected Bank to the Agent and the Borrower), all Eurodollar Rate Advances of such Affected Bank shall be deemed to be Converted to Base Rate Advances (but will otherwise
        continue to be considered as a part of the respective Borrowings that they were a part of prior to such Conversion); provided, however, that, before making any such demand, such Bank agrees to use reasonable efforts (consistent with its internal policy and legal and regulatory
        restrictions) to designate a different Eurodollar Lending Office if the making of such a designation would allow such Bank or its Eurodollar Lending Office to continue to perform its obligations to make Eurodollar Rate Advances or to continue to
        fund or maintain Eurodollar Rate Advances and would not, in the judgment of such Bank, be otherwise materially disadvantageous to such Bank.  In the event any Bank shall notify the Agent of the occurrence of any circumstance contemplated under this
        Section 2.15, all payments and prepayments of principal that would otherwise have been applied to repay the Eurodollar Rate Advances that would have been made by such Bank or the Converted Eurodollar Rate Advances shall instead be applied to repay
        the Base Rate Advances made by such Bank in lieu of such Eurodollar Rate Advances or resulting from the Conversion of such Eurodollar Rate Advances and shall be made at the time that payments on the Eurodollar Rate Advances of the Banks that are
        not Affected Banks are made.  Each Bank that has delivered a notice of illegality pursuant to this Section 2.15 above agrees that it will notify the Borrower as soon as practicable if the conditions giving rise to the illegality cease to exist.

    Section 2.16          Conversion of Advances.  The Borrower may on any Business Day, upon notice given to the Agent not later than 11:00 A.M. (New York City time) on
        the third Business Day prior to the date of the proposed Conversion and subject to the provisions of Sections 2.02(b), 2.09 and 2.15, Convert all Advances of one Type comprising the same Borrowing into Advances of the other Type; provided, however, that (a) any Conversion of any Eurodollar Rate
        Advances into Base Rate Advances shall be made on, and only on, the last day of an Interest Period for such Eurodollar Rate Advances, except as provided in Section 2.15, (b) Advances comprising a Borrowing may not be Converted into Eurodollar Rate
        Advances if the outstanding principal amount of such Borrowing is less than $10,000,000 or if any Event of Default under Section 6.01(a) or Section 6.01(e) shall have occurred and be continuing on the date the related notice of Conversion would
        otherwise be given pursuant to this Section 2.16 and (c) a Swingline Advance may not be Converted into Eurodollar Rate Advances.  Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such
        Conversion, (ii) the Advances to be Converted and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Advance.  Each notice of Conversion shall be irrevocable and binding on the
        Borrower.  If any Event of Default under Section 6.01(a) or Section 6.01(e) shall have occurred and be continuing on the third Business Day prior to the last day of any Interest Period for any Eurodollar Rate Advances, the Borrower agrees to
        Convert all such Advances into Base Rate Advances on the last day of such Interest Period.

    Section 2.17          Replacement or Removal of Bank.  In the event that any Bank shall claim payment of any increased costs pursuant to Section 2.12 or the Borrower
        is required to pay any Additional Amounts, Taxes or Other Taxes to or on account of any Bank pursuant to Section 2.13, or any Bank exercises its rights under Section 2.15, or if any Bank fails to execute and deliver a consent, amendment or waiver
        to this Agreement requested by the Borrower by the date specified by the Borrower (or gives the Borrower written notice prior to such date of its intention not to do so) and such consent, amendment or waiver requires the consent of such Bank and
        the Required Banks have granted their consent, or any Bank is a Defaulting Bank or a Potential Defaulting Bank, the Borrower shall have the right to (a) replace such Bank with an Eligible Assignee in accordance with Section 8.08(a), (b) and (d)
        (including execution of an appropriate Assignment and Acceptance); provided that such Eligible Assignee (i) shall unconditionally offer in writing (with a
        copy to the Agent) to purchase on a date therein specified all of such Bank’s rights hereunder and interest in the Advances owing to such Bank and the Note held by such Bank without recourse at the principal amount of such Note plus interest,
        Commitment Fees and Letter of Credit fees accrued thereon to the date of such purchase and (ii) shall execute and deliver to the Agent an Assignment and Acceptance, as assignee, pursuant to which such Eligible Assignee becomes a party hereto with a
        Revolving Credit Commitment equal to that of the Bank being replaced (plus, if such Eligible Assignee is already a Bank, the amount of its Revolving Credit Commitment prior to such replacement), provided further, that no Bank or other Person shall have any obligation to increase its Commitment or otherwise to replace, in whole or in part, any Bank or (b) if no Default or Event of Default then
        exists, remove such Bank without replacing it by (i) giving notice to such Bank and the Agent of such removal and (ii) simultaneously with such notice paying to the Agent for the account of such Bank all principal owed to such Bank, all accrued
        interest, Commitment Fees and Letter of Credit fees owed to such Bank, all requested costs accruing to the date of removal which the Borrower is obligated to pay to such Bank under Section 8.04 and all other amounts owed by the Borrower to such
        Bank under this Agreement; provided that if the Bank being replaced or removed pursuant to this sentence is an Issuing Bank, the Borrower shall take such
        steps (which may include delivery of cash collateral) requested by such Issuing Bank to fully protect such Issuing Bank from any loss, cost, expense or liability related to or in connection with any Letter of Credit issued by such Issuing Bank. 
        Upon satisfaction of the requirements for replacement set forth in the first sentence of this Section 2.17, payment to such Bank of the purchase price in immediately available funds by the Eligible Assignee replacing such Bank, execution of such
        Assignment and Acceptance by such Bank (which Bank shall execute such Assignment and Acceptance contemporaneously with or prior to the payment of all amounts required to be paid to it pursuant to this sentence; provided that such Bank shall be deemed to have executed such Assignment and Acceptance if it shall have not executed such assignment within ten (10) Business Days after the request to
        sign such assignment), such Eligible Assignee and the Agent, the payment by the Borrower of all requested costs accruing to the date of purchase which the Borrower is obligated to pay under Section 8.04 and all other amounts owed by the Borrower to
        such Bank under this Agreement (other than Commitment Fees and Letter of Credit fees accrued for the account of such Bank and the principal of and interest on the Advances of such Bank purchased by such Eligible Assignee) and notice by the Borrower
        to the Agent that such payment has been made, such Eligible Assignee shall constitute a “Bank” hereunder with a Revolving Credit Commitment as so specified and the Bank being so replaced shall no longer constitute a “Bank” hereunder except that the
        rights under Sections 2.08, 2.12, 2.13 and 8.04 of the Bank being so replaced shall continue with respect to events and occurrences occurring

     

      

    
      43

      
        


    

     before or concurrently with its ceasing to be a “Bank” hereunder.  If, however, such Eligible Assignee fails to purchase such rights
        and interest on such specified date in accordance with the terms of such offer or such Eligible Assignee or the Agent fails to execute the relevant Assignment and Acceptance, the Borrower shall continue to be obligated to pay the increased costs to
        such Bank pursuant to Section 2.12 or the Additional Amounts pursuant to Section 2.13, as the case may be.  Upon satisfaction of the requirements for removal set forth in the first sentence of this Section 2.17, the Bank being so removed shall no
        longer constitute a “Bank” hereunder except that the rights under Sections 2.08, 2.12, 2.13 and 8.04 of the Bank being so removed shall continue with respect to events and occurrences occurring before or concurrently with its ceasing to be a “Bank”
        hereunder.

    Section 2.18          Evidence of Indebtedness.  Each Bank shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of
        the Borrower to such Bank resulting from each Advance owing to such Bank from time to time, including the amounts of principal and interest payable and paid to such Bank from time to time hereunder.  The Borrower agrees that upon notice by any Bank
        to the Borrower (with a copy of such notice to the Agent) to the effect that a promissory note or other evidence of indebtedness is required or appropriate in order for such Bank to evidence (whether for purposes of pledge, enforcement or
        otherwise) the Advances owing to, or to be made by, such Bank, the Borrower shall promptly execute and deliver to such Bank, with a copy to the Agent, a Revolving Note in substantially the form of Exhibit A-1 hereto, payable to the order of such
        Bank in a principal amount equal to the Revolving Credit Commitment of such Bank.  The Borrower agrees that upon notice by the Swingline Bank to the Borrower (with a copy of such notice to the Agent) to the effect that a promissory note or other
        evidence of indebtedness is required or appropriate in order for the Swingline Bank to evidence (whether for purposes of pledge, enforcement or otherwise) the Swingline Advances owing to, or to be made by, the Swingline Bank, the Borrower shall
        promptly execute and deliver to the Swingline Bank, with a copy to the Agent, a Swingline Note in substantially the form of Exhibit A-2 hereto, payable to the order of such Bank in a principal amount equal to the Swingline Sublimit.  All references
        to Notes in the Loan Documents shall mean Notes, if any, to the extent issued hereunder.

    Section 2.19          [Reserved].

    Section 2.20          Increase in the Aggregate Revolving Credit Commitments.  (a) The Borrower may, from time to time at least 90 days prior to the latest Stated
        Termination Date for any Bank, by notice to the Agent, request that the aggregate amount of the Revolving Credit Commitments be increased by a minimum amount of $25,000,000 or an integral multiple of $5,000,000 in excess thereof (each a “Commitment Increase”) to be effective as of a date that is at least 90 days prior to the latest Stated Termination Date for any Bank (the “Increase Date”) as specified in the related notice to the Agent; provided,
        however that (i) in no event shall the aggregate amount of all increases effected pursuant to this Section 2.20 exceed $500,000,000 and (ii) on the date of
        any request by the Borrower for a Commitment Increase and on the related Increase Date, the applicable conditions set forth in Article III shall be satisfied.

    (b)          The Agent shall promptly notify the Banks of a request by the Borrower for a Commitment Increase, which notice shall include (i) the proposed amount of such requested Commitment Increase, (ii) the proposed Increase Date and (iii) the date
        by which Banks wishing to participate in the Commitment Increase must commit to an increase in the amount of their respective

     

      

    
      44

      
        


    

     Revolving Credit Commitments (the “Commitment Date”).  Each Bank that is willing to participate in such requested Commitment Increase (each an “Increasing


            Lender”) shall, in its sole discretion, give written notice to the Agent on or prior to the Commitment Date of the amount by which it is willing to increase its Revolving Credit Commitment.

    (c)          Promptly following each Commitment Date, the Agent shall notify the Borrower as to the amount, if any, by which Banks are willing to participate in the requested Commitment Increase.  If the aggregate amount by which Banks are willing to
        participate in any requested Commitment Increase on any such Commitment Date is less than the requested Commitment Increase, then the Borrower may extend offers to one or more Eligible Assignees to participate in any portion of the requested
        Commitment Increase that has not been committed to by Banks as of the applicable Commitment Date; provided, however, that the Revolving Credit Commitment of each such Eligible Assignee shall be in an amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof.  The Borrower, at its
        discretion, may withdraw its request for a Commitment Increase at any time prior to the Increase Date.

    (d)          On each Increase Date, (i) each Eligible Assignee that accepts an offer to participate in a requested Commitment Increase in accordance with Section 2.20(c) (each such Eligible Assignee, an “Assuming Lender”) shall become a Bank party to this Agreement as of such Increase Date and (ii) the Revolving Credit Commitment of each Increasing Lender for such requested Commitment Increase shall
        be so increased by the amount allocated to such Bank as agreed between the Borrower and the Agent (not to exceed the amount by which such Bank was willing to increase its Revolving Credit Commitment (as specified in such Bank’s relevant notice
        pursuant to Section 2.20(b))); provided, however, that the Agent
        shall have received on or before such Increase Date the following, each dated such date:

    
      	
              (A)

            	
              an assumption agreement from each Assuming Lender, if any, in form and
                  substance satisfactory to the Borrower and the Agent (each an “Assumption Agreement”), duly executed by such Assuming Lender, the Agent and the
                  Borrower; and

            


    

    
      	
              (B)

            	
              confirmation from each Increasing Lender of the increase in the amount of
                  its Commitment in a writing satisfactory to the Borrower and the Agent.

            


    

    On each Increase Date, upon fulfillment of the conditions set forth in the immediately preceding sentence of this
        Section 2.20(d), the Agent shall notify the Banks (including, without limitation, each Assuming Lender) and the Borrower, on or before 1:00 P.M. (New York City time), by electronic communication (e-mail), of the occurrence of the Commitment
        Increase to be effected on such Increase Date and shall record in the Register the relevant information with respect to each Increasing Lender and each Assuming Lender on such date.  On the last day of each Interest Period in effect on any Increase
        Date, the Borrower shall make such Borrowings and prepayments as shall be necessary to cause the outstanding Eurodollar Rate Advances related to such Interest Period and, in the case of the first such Interest Period, the Base Rate Advances to be
        ratable with the revised Commitments resulting from any non-ratable increase in the Commitments under this Section 2.20.

     

      

    
      45

      
        


    

    (e)          Notwithstanding any other provision of this Section 2.20, no increase of any Commitment shall be effected pursuant to this Section 2.20 without the consent of the Agent, the Issuing Banks and the Swingline Bank (which consents shall not
        be unreasonably withheld, delayed or conditioned).

    Section 2.21          New Issuing Banks.  From time to time, with the approval of the Agent (which approval shall not be unreasonably withheld), the Borrower may enter
        into an agreement with a Person that is not already an Issuing Bank hereunder pursuant to which such Person shall become an Issuing Bank hereunder, if (a) such agreement provides that such Person expressly agrees to perform in accordance with their
        terms all the obligations that by the terms of this Agreement are required to be performed by it as an Issuing Bank, (b) such agreement sets forth such Person’s Applicable Lending Office and the amount of its Letter of Credit Commitment (which
        information shall be recorded by the Agent in the Register) and (c) a copy of such agreement is promptly delivered to the Agent.

    Section 2.22          Extension of Commitments.   (a) The Borrower may request by notice (an “Extension Request Notice”) to the Agent (which shall promptly notify the Banks), given during any period beginning on (and including) the day that is 75 days prior to an anniversary of the Effective Date and ending on (and
        including) the day that is 30 days prior to such anniversary, but in no event later than 30 days prior to the latest Stated Termination Date for any Bank, that the Banks extend their respective Revolving Credit Commitments for an additional year; provided that the Borrower may effectuate an extension pursuant to this Section 2.22 only two times; provided further that the Borrower agrees that it shall not make such request unless on the date of such request it
        has satisfied all conditions that would be required pursuant to Article III for a Revolving Credit Advance on such date (other than the giving of a Notice of Revolving Credit Borrowing).  If a Bank agrees, in its sole and absolute discretion, to so
        extend its Revolving Credit Commitment, it will give notice to the Agent of its decision to do so within the ten day period following the date of such Extension Request Notice.  Promptly following expiration of such ten day period, the Agent will
        notify the Borrower and the Banks of the Banks from which it has received such a notice agreeing to so renew (“Extending Banks”).  Any failure by a Bank to
        so notify the Agent shall be deemed to be a decision by such Bank to not so extend its Revolving Credit Commitment (each a “Non-Extending Bank”).

    (b)          If all Banks elect to so extend their respective Revolving Credit Commitments, the Stated Termination Date for each Bank shall automatically become the date that is one year following the Stated Termination Date for such Bank as in effect
        immediately prior to such extension.

    (c)          The Borrower shall have the right, on or before the anniversary of the Effective Date in respect of which an Extension Request Notice is given, to replace each Non-Extending Bank with, and add as “Banks” under this Agreement in place
        thereof, one or more Eligible Assignees (each, an “Additional Commitment Bank”) as provided in Section 8.08, each of which Additional Commitment Banks shall
        have entered into an Assignment and Acceptance pursuant to which such Additional Commitment Bank shall, effective as of such anniversary, undertake a Revolving Credit Commitment (and, if any such Additional Commitment Bank is already a Bank, its
        Revolving Credit Commitment shall be in addition to any other Revolving Credit Commitment of such Bank hereunder on such date).

     

      

    
      46

      
        


    

    (d)          If the Revolving Credit Commitments of the Extending Banks and the Additional Commitment Banks aggregate 50% or less of the aggregate Revolving Credit Commitments of all Banks, none of the Revolving Credit Commitments (including the
        Revolving Credit Commitment of any Extending Bank) will be extended and the Stated Termination Date for each Bank shall remain unchanged.

    (e)          If the Revolving Credit Commitments of the Extending Banks and the Additional Commitment Banks aggregate greater than 50% and less than 100% of the aggregate Revolving Credit Commitments of all Banks, (i) the Stated Termination Date for
        each Bank that is an Extending Bank or an Additional Commitment Bank shall automatically become the date that is one year following the Stated Termination Date for such Bank (or in the case of an Additional Commitment Bank that was not already a
        Bank with a Revolving Credit Commitment, one year following the Stated Termination Date of the Bank it replaced) as in effect immediately prior to such extension, (ii) the Stated Termination Date for each Bank that is a Non-Extending Bank shall
        remain unchanged and (iii) each Additional Commitment Bank shall thereupon become a “Bank” for all purposes of this Agreement with a Revolving Credit Commitment as contemplated by Section 2.22(c).

    (f)          The election by any Bank to renew at any time shall not obligate such Bank to renew at any other time, it being agreed that each election of any Bank to renew or not renew shall be made by such Bank in its sole and absolute discretion and
        that such discretion shall not be limited by any prior election to renew.

    (g)          The Borrower agrees to deliver to the Agent on each date that any extension pursuant to this Section 2.22 becomes effective a certificate of a Responsible Officer to the effect that on such date the Borrower has satisfied all conditions
        that would be required pursuant to Article III for a Revolving Credit Advance on such date (other than the giving of a Notice of Revolving Credit Borrowing).

    Section 2.23          Change in Control.  (a)  If a Change in Control occurs, (i) the Borrower shall promptly notify the Agent (which shall promptly notify the Banks)
        of such occurrence and specify in such notice a date (the “Early Maturity Date”) on which the matters referred to in clauses (ii) and (iii) of this
        Section 2.23(a) shall occur as to each Bank, at the option of such Bank, which date shall be any Business Day not earlier than 60 days after, and not later than 90 days after, the Borrower gives such notice, (ii) any Bank may, at its sole option,
        elect to require the following to occur on the Early Maturity Date: (A) termination of its Revolving Credit Commitment, if any, (B) payment in full by the Borrower of all Obligations owed to such Bank and (C) grant by the Borrower of a first
        priority perfected security interest in, and delivery by the Borrower to each Issuing Bank, for such Issuing Bank’s sole benefit, of, an amount in Dollars and in same day funds equal to such Bank’s Pro Rata Share of all outstanding Letters of
        Credit issued by such Issuing Bank, to be held as cash collateral by such Issuing Bank under the sole control and dominion of such Issuing Bank and subject to the terms of 

     

      

    
      47

      
        


    

    this Agreement; provided that any
        such election shall elect all (and not less than all) of the actions referred to in such clauses (A), (B) and (C), and (iii) any Issuing Bank may, at its sole option, elect to require the following to occur on the Early Maturity Date:
        (A) termination of its Letter of Credit Commitment, if any, (B) payment in full by the Borrower of all Obligations owed to such Issuing Bank and (C) grant by the Borrower of a first priority perfected security interest in, and delivery by the
        Borrower to such Issuing Bank, for such Issuing Bank’s sole benefit, of, an amount in Dollars and in same days funds equal to the Available Amount of all outstanding Letters of Credit issued by such Issuing Bank (but without duplication of amounts,
        if any, delivered in respect of such Letters of Credit pursuant to Section 2.23(a)(ii)(C)), to be held as cash collateral by such Issuing Bank under the sole control and dominion of such Issuing Bank and subject to the terms of this Agreement; provided that any such election shall elect all (and not less than all) of the actions referred to in such clauses (A), (B) and (C).  Any Bank that is
        also an Issuing Bank and elects to exercise its rights under clause (ii) or (iii) of this Section 2.23(a) shall elect to exercise its rights under both such clauses.

    (b)          Any Bank (an “Exercising Bank”) may exercise its rights pursuant to Section 2.23(a) by giving the Agent and the Borrower a written notice of such
        exercise not earlier than 20 days after, and not later than 40 days after, such Bank’s receipt of a notice from the Agent under Section 2.23(a) (but the failure to so exercise such rights in respect of any Change in Control shall not impair the
        exercise of any such rights in respect of any other Change in Control).

    (c)          On the relevant Early Maturity Date, each Exercising Bank’s Revolving Credit Commitment shall terminate, and the Borrower shall (i) pay in full all Obligations owed to such Bank hereunder, including all of such Bank’s outstanding Advances
        together with interest thereon accrued to such Early Maturity Date and any amounts payable pursuant to Section 8.04(b), all Commitment Fees and Letter of Credit fees accrued to such Early Maturity Date with respect to such Bank’s Revolving Credit
        Commitment and all amounts then owing to such Bank pursuant to Sections 2.08, 2.12, 2.13 and 8.04, (ii) grant the security interest and deliver to the relevant Issuing Banks the respective amounts contemplated by clause (ii)(C) of Section 2.23(a)
        and (iii) if immediately after giving effect to such termination and payment, the sum of the aggregate Available Amount of all outstanding Letters of Credit plus the aggregate principal amount of all outstanding Letter of Credit Advances would
        exceed the Revolving Credit Facility, pay to the Agent in same day funds at the Agent’s office, for deposit in the Cash Collateral Account, an amount equal to such excess; provided that such termination of such Bank’s Revolving Credit Commitment shall not occur until the requirements of clause (ii) of this sentence and this clause (iii) are satisfied, but effective as of the Early Maturity
        Date such Bank shall have no further obligation to make any Revolving Credit Advance, no obligation to make Letter of Credit Advances in respect of Letters of Credit issued after such Early Maturity Date and no obligation to purchase any share or
        portion of any Letter of Credit Advance in respect of Letters of Credit issued or Swingline Advances made after such Early Maturity Date.  Upon termination of such Bank’s Revolving Credit Commitment in accordance with this Section 2.23(c), such
        Bank shall cease to be a party hereto, except that (A) rights of such Bank under Sections 2.08, 2.12, 2.13 and 8.04 shall continue with respect to events and occurrences occurring before or on such Early Maturity Date, (B) the obligations of such
        Bank under Section 7.07 shall continue as to events,

     

      

    
      48

      
        


    

    actions and circumstances arising on or prior to such Early Maturity Date and (C) such Bank shall be liable to
        each Issuing Bank for such Bank’s Pro Rata Share of any loss incurred by such Issuing Bank as a result of the collateral provided pursuant to this Section 2.23 to such Issuing Bank being inadequate for any reason, but no Issuing Bank, solely in its
        capacity as such, shall be liable to another Issuing Bank under this clause (C).  Nothing contained in this Section 2.23 shall impair the obligation of the Borrower to pay any amount owing to the Banks hereunder when due prior to an Early Maturity
        Date.

    (d)          On the relevant Early Maturity Date, such Exercising Bank’s Letter of Credit Commitment shall terminate, and the Borrower shall (i) pay in full all Obligations owed to such Issuing Bank, including all of such Issuing Bank’s outstanding
        Advances together with interest thereon accrued to such Early Maturity Date and any amounts payable pursuant to Section 8.04(b), all Letter of Credit fees and all amounts then owing to such Issuing Bank pursuant to Sections 2.12, 2.13 and 8.04 and
        (ii) grant the security interest and deliver to such Issuing Bank the amount contemplated by Section 2.23(a)(iii)(C).  Nothing contained in this Section 2.23 shall impair the obligation of the Borrower to pay any amount owing to the Issuing Banks
        hereunder when due prior to an Early Maturity Date.

    (e)          The Borrower shall have the right, on or before the Early Maturity Date, to replace each Exercising Bank with, and add as “Banks” under this Agreement in place thereof, one or more Eligible Assignees (each, an “Additional Change in Control Commitment Bank”) as provided in Section 8.08, each of which Additional Change in Control Commitment Banks shall have entered into an Assignment and
        Acceptance pursuant to which such Additional Change in Control Commitment Bank shall, effective as of such Early Maturity Date, undertake a Revolving Credit Commitment or Letter of Credit Commitment, as the case may be (and, if any such Additional
        Change in Control Commitment Bank is already a Bank, its Revolving Credit Commitment or Letter of Credit Commitment, as the case may be, shall be in addition to any other Revolving Credit Commitment or Letter of Credit Commitment, as the case may
        be, of such Bank hereunder on such date).

    Section 2.24          Defaulting Bank Provisions.  If a Bank becomes, and during the period it remains, a Defaulting Bank, the following provisions shall apply:

    (a)          the Defaulting Bank Exposure of such Defaulting Bank will, subject to the limitation in the first proviso below, automatically be reallocated (effective on the day such Bank becomes a Defaulting Bank) among the Non-Defaulting Banks pro rata in accordance with their respective Revolving Credit
        Commitments; provided that (i) the sum of all Non-Defaulting Banks’ Unused Revolving Credit Commitments may not in any event be less than zero as in effect
        at the time of such reallocation and (ii) neither such reallocation nor any payment by a Non-Defaulting Bank pursuant thereto will constitute a waiver or release of any claim the Borrower, the Agent, an Issuing Bank, the Swingline Bank or any other
        Bank may have against such Defaulting Bank or cause such Defaulting Bank to be a Non-Defaulting Bank;

    (b)          to the extent that any portion (the “unreallocated portion”) of the Defaulting Bank Exposure cannot be so reallocated, whether by reason of the
        first proviso in Section 2.24(a) or otherwise, the Borrower will, not later than three (3) Business Days after demand by the Agent (at the direction of an Issuing Bank and/or the Swingline Bank, as the case may be), (i) pay to the Agent in same day
        funds at the Agent’s office, for deposit in the Cash Collateral Account, an amount equal to the unreallocated portion of such Defaulting Bank Exposure, (ii) prepay (subject to clause (c) below) the Swingline Advances and/or (iii) make other
        arrangements satisfactory to the Agent, the Issuing Banks and the Swingline Bank, as the case may be, in their sole discretion to protect them against the risk of non-payment by such Defaulting Bank; and

     

      

    
      49

      
        


    

    (c)          if the Borrower, the Agent, the Issuing Banks and the Swingline Bank agree in writing in their discretion that a Bank is no longer a Defaulting Bank or a Potential Defaulting Bank, as the case may be, the Agent will so notify the parties
        hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any amounts then held in the Cash Collateral Account), such Bank will, to the extent
        applicable, purchase at par such portion of outstanding Advances of the other Banks and/or make such other adjustments as the Agent may determine to be necessary to cause the Unused Revolving Credit Commitments of the Banks to be on a pro rata basis in accordance with their respective Revolving Credit
        Commitments, whereupon such Bank will cease to be a Defaulting Bank or Potential Defaulting Bank and will be a Non-Defaulting Bank (and the Defaulting Bank Exposure of each Bank will automatically be adjusted on a prospective basis to reflect the
        foregoing); provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while such
        Bank was a Defaulting Bank; and provided further that except to
        the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Bank or Potential Defaulting Bank to Non-Defaulting Bank will constitute a waiver or release of any claim of any party hereunder arising from such
        Bank’s having been a Defaulting Bank or Potential Defaulting Bank.

    Section 2.25          Acknowledgment and Consent to Bail-In of EEA Financial Institutions.  Notwithstanding anything to the contrary in any Loan Document or in any
        other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to
        the Write-Down and Conversion Powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

    (a)          the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder that may be payable to it by any party hereto that is an EEA Financial Institution; and

    (b)          the
        effects of any Bail-in Action on any such liability, including, if applicable:

    (i)          a reduction in full or in part or cancellation of any such liability;

    (ii)          a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on
        it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

    (iii)          the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of any EEA Resolution Authority.

        an officer of the Agent responsible for the transactions contemplated by this Agreement shall have received notice from such Person prior to the date that the Borrower, by notice to the Agent, designates as the proposed Effective Date, specifying
        its objection thereto.  The Agent shall promptly notify the Banks and the Borrower of the occurrence of the Effective Date, which notice shall be conclusive and binding.

    Section 3.04          Additional Defaulting Bank Requirements.  In addition to the other conditions precedent herein set forth, if any Bank becomes, and during the
        period it remains, a Defaulting Bank or a Potential Defaulting Bank, no Issuing Bank will be required to issue any Letter of Credit or to amend any outstanding Letter of Credit and the Swingline Bank will not be required to make any Swingline
        Advances, unless such Issuing Bank or the Swingline Bank, as the case may be, is satisfied that any exposure that would result therefrom is eliminated or fully covered by the Revolving Credit Commitments of the Non-Defaulting Banks or by deposits
        in the Cash Collateral Account or a combination thereof satisfactory to the Issuing Banks or Swingline Bank.

    ARTICLE IV

        such power and authority as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

     

      

    
      53

        manner draws into question or purports to affect any transaction contemplated hereby or the legality, validity, binding effect or enforceability of the Borrower’s obligations or the rights and remedies of the Banks relating to this Agreement and
        the other Loan Documents.

    (g)          Neither the Borrower nor any Subsidiary is engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U).  Following the application of the proceeds of each Advance

        all or any portion of the Advances or any other amount payable hereunder or under any such other arrangement), will be any such margin stock.  No proceeds of any Advance or any Letter of Credit will be used in any manner that is not permitted by

        by the Loan Documents (as modified or supplemented by other information furnished) contains as of the date such statement, information, document or certificate was so furnished any untrue statement of a material fact or omitted to state a material
        fact necessary in order to make the statements contained herein or therein not misleading in light of the circumstances under which they were made; provided,

        statements and projections regarding the future performance of the Borrower or any of its Subsidiaries (“Projections”), no representation or warranty is made

        proceeding shall remain undismissed or unstayed for a period of 90 days, or any of the actions sought in such proceeding (including, without limitation, the entry of an order for relief against, or the appointment of a receiver, trustee, custodian
        or other similar official for, it or for any substantial part of its Property) shall occur, or shall be consented to or acquiesced in by the Borrower or such material Subsidiary; or the Borrower or any such material Subsidiary shall take any

    (g)          The Borrower or any of its ERISA Affiliates shall both (i) incur liability in excess of $250,000,000 in the aggregate as a result of one or more of the following: (A) the occurrence of any ERISA Event; (B) the partial or complete
        withdrawal of the Borrower or any of its ERISA Affiliates from a Multiemployer Plan; or (C) the reorganization or termination of a Multiemployer Plan and (ii) fail to pay such liability within fifteen days of such incurrence;

    then, and in any such event, the Agent (y) shall at the request, or may with the consent, of the Required Banks, by
        notice to the Borrower, declare the obligation of each Bank to make Advances (other than Letter of Credit Advances by an Issuing Bank or a Bank pursuant to Section 2.03(c)) and of each Issuing Bank to issue Letters of Credit to be terminated,
        whereupon the same (and all of the Commitments) shall forthwith terminate, and (z) shall at the request, or may with the consent, of the Required Banks, by notice to the Borrower, declare the Advances, all interest thereon and all other amounts
        payable under this Agreement to be forthwith due and payable, whereupon the Advances, all such interest and all such other amounts shall become and be forthwith due and payable, without presentment, demand, protest, notice of intent to accelerate,

        make Advances (other than Letter of Credit Advances by an Issuing Bank or a Bank pursuant to Section 2.03(c)) and of each Issuing Bank to issue Letters of Credit shall automatically be terminated, and (2) the Advances, all interest thereon and all
        other amounts payable under this Agreement shall automatically and immediately become and be due and payable, without presentment, demand, protest, notice of intent to accelerate, notice of acceleration, or any other notice of any kind, all of
        which are hereby expressly waived by the Borrower.

    Section 6.02          Actions in Respect of the Letters of Credit upon Default.  If any Event of Default shall have occurred and be continuing, the Agent may, or shall
        at the request of the Required Banks, irrespective of whether it is taking any of the actions described in Section 6.01 or otherwise, make demand upon the Borrower to, and forthwith upon such demand the Borrower will, pay to the Agent on behalf of
        the Banks in same day funds at the Agent’s office designated in such demand, for deposit in the Cash Collateral Account, an amount equal to the aggregate Available Amount of all Letters of Credit then outstanding; provided, however, that upon the occurrence of any Event of Default described in Section
        6.01(e) with respect to the Borrower, the Borrower shall be obligated to pay to the Agent on behalf of the Banks in same day funds at the Agent’s office, for deposit in the Cash Collateral Account, an amount equal to the aggregate Available Amount
        of all Letters of Credit then outstanding. If at any time the Agent determines that any funds held in the Cash Collateral Account are subject to any right or claim of any Person other than the Agent and the Banks 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 Agent, pay to the Agent, as additional funds to be deposited and held in the 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 Cash Collateral Account that the Agent determines to be free and clear of all such rights and claims.  Upon the drawing of any Letter of
        Credit for which funds are on deposit in the Cash Collateral Account, such funds shall be applied to reimburse the relevant Issuing Bank or the Banks, as applicable, to the extent permitted by applicable law.

    ARTICLE VII

        

        THE AGENT

    Section 7.01          Authorization and Action.  Each Bank hereby appoints and authorizes the Agent to take such action as Agent on its behalf and to exercise such
        powers under the Loan Documents as are delegated to the Agent by the terms hereof or of any other Loan Document, together with such powers and discretion as are reasonably incidental thereto.  As to any matters not expressly provided for by this
        Agreement (including, without limitation, enforcement or collection of the Notes), the 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 Banks and such instructions shall be binding upon all Banks and all holders of Notes; provided,
        however, that the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to any Loan Document or
        applicable law.  The Agent agrees to give to each Bank prompt notice of each notice given to it by the Borrower, and, promptly, copies of any document, instrument or agreement provided to it by the Borrower, pursuant to the terms of this
        Agreement.  The provisions of this Article are solely for the benefit of the Agent, the Banks, the Issuing Banks and the Swingline Bank, and the Borrower shall not have rights as a third party beneficiary of any of such provisions.

    Section 7.02          Agent’s Reliance, Etc.  Neither the Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted
        to be taken by it or them under or in connection with any Loan Document, except for their own gross negligence or willful misconduct.  Without limitation of the generality of the foregoing, the Agent:  (i) may consult with legal counsel (including,
        without limitation, counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel,
        accountants or experts; (ii) makes no warranty or representation to any Bank and shall not be responsible to any Bank for any statements, warranties or representations (whether written or oral) made in or in connection with any of the Loan
        Documents or any other instrument or document; (iii) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of any of the Loan Documents or any other instrument or
        document on the part of the Borrower or any Subsidiary of the Borrower or to inspect the Property (including the books and records) of the Borrower or any Subsidiary of the Borrower; (iv) shall not be responsible to any Bank for the due execution,
        legality, validity, enforceability, genuineness, sufficiency or value of any of the Loan Documents or any other instrument or document; (v) shall incur no liability under or in respect of any of the Loan Documents or any other instrument or
        document by acting upon any notice (including telephonic notice), consent, certificate or other instrument or writing (which may be by facsimile or other electronic communication) believed by it to be genuine and signed, given or sent by the proper
        party or parties and (vi) shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, 

    
      66

      
        


    

    consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or
        other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person.  The Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by
        the proper Person, and shall not incur any liability for relying thereon.  In determining compliance with any condition hereunder to the making of an Advance, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the
        satisfaction of a Bank or an Issuing Bank, the Agent may presume that such condition is satisfactory to such Bank or Issuing Bank unless the Agent shall have received notice to the contrary from such Bank or Issuing Bank prior to the making of such
        Advance or the issuance of such Letter of Credit.

    Section 7.03          Exculpatory Provisions.  The Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan
        Documents.  Without limiting the generality of the foregoing, the Agent:

    (a)          shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing;

    (b)          shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as
        directed in writing by the Required Banks (or such other number or percentage of the Banks as shall be expressly provided for herein or in the other Loan Documents), provided
        that the Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Agent to liability or that is contrary to any Loan Document or applicable law; and

    (c)          shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is
        communicated to or obtained by the Person serving as the Agent or any of its Affiliates in any capacity.

    The Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the
        Required Banks (or such other number or percentage of the Banks as shall be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Article VI or Section 8.01) or (ii) in the absence of its
        own gross negligence or willful misconduct.  The Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Agent by the Borrower, a Bank, an
        Issuing Bank or the Swingline Bank.

    The Agent shall not be responsible for or have any duty to ascertain or inquire into (A) any statement, warranty or
        representation made in or in connection with this Agreement or any other Loan Document, (B) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (C) the performance or
        observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (D) the validity, enforceability, effectiveness or genuineness of this Agreement, any
        other Loan Document or any other agreement, instrument or document or (E) the satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent.

        Document by or through any one or more sub-agents appointed by the Agent.  The Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties.  The exculpatory
        provisions of this Article shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for
        herein as well as activities as Agent.

    Section 7.05          The Agent and its Affiliates.  With respect to its Commitment, the Advances owed to it and the Notes issued to it, each Bank which is also the
        Agent shall have the same rights and powers under this Agreement as any other Bank and may exercise the same as though it were not the Agent; and the term “Bank” or “Banks” shall, unless otherwise expressly indicated, include any Bank serving as
        the Agent in its individual capacity.  Any Bank serving as the Agent and its affiliates may accept deposits from, lend money to, act as trustee under indentures of, accept investment banking engagements from and generally engage in any kind of
        business with, the Borrower, any Affiliate of the Borrower and any Person who may do business with or own securities of the Borrower or any Affiliate of the Borrower, all as if such Bank were not the Agent and without any duty to account therefor
        to the Banks.  In the event that Citi or any of its Affiliates shall be or become an indenture trustee under the Trust Indenture Act of 1939 (as amended, the “Trust
            Indenture Act”) in respect of any securities issued or guaranteed by the Borrower, the parties hereto acknowledge and agree that any payment or property received in satisfaction of or in respect of any Obligation of the Borrower
        hereunder or under any other Loan Document by or on behalf of Citi in its capacity as the Agent for the benefit of any Bank under any Loan Document (other than Citi or an Affiliate of Citi) and which is applied in accordance with the Loan Documents
        shall be deemed to be exempt from the requirements of Section 311 of the Trust Indenture Act pursuant to Section 311(b)(3) of the Trust Indenture Act.

    Section 7.06          Bank Credit Decision.  Each Bank acknowledges that it has, independently and without reliance upon the Agent or any other Bank and based on the
        Financial Statements and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement.  Each Bank also acknowledges that it will, independently and without reliance upon
        the Agent or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents or any other instrument or document.

    Section 7.07          Indemnification.  The Banks (other than the Issuing Banks and the Swingline Bank) agree to indemnify the Agent,
        each of its Affiliates and each of their respective directors, officers, employees, agents, advisors and representatives (to the extent not timely reimbursed by the Borrower), ratably according to the respective principal amounts of the Advances
        then held by each of such Banks (or if no Advances are at the time outstanding or if any Advances (other than Letter of Credit Advances held by an Issuing Bank or Swingline Advances held by the Swingline Bank) are held by Persons which are not such
        Banks, ratably according to either (a) the respective amounts of the Banks’ Revolving Credit Commitments, or (b) if no Revolving Credit Commitments are at the time outstanding, the respective amounts of the Revolving Credit Commitments immediately
        prior to the time the Revolving Credit

    
      68

      
        


    

     Commitments ceased to be outstanding), from and against any and all claims, damages, losses, liabilities and
        expenses (including, without limitation, fees and expenses of counsel) of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in connection with such capacity in any way relating to or arising out of
        any of the Loan Documents or any other instrument or document furnished pursuant hereto or in connection herewith, or any action taken or omitted by the Agent under any of the Loan Documents or any other instrument or document furnished pursuant
        hereto or in connection herewith (“Indemnified Costs”); provided
        that no Bank shall be liable for any portion of any and all claims, damages, losses, liabilities and expenses (including, without limitation, fees and expenses of counsel) resulting from the Agent’s gross negligence or willful misconduct as found
        in a final, non-appealable judgment by a court of competent jurisdiction.  Without limitation of the foregoing, each Bank (other than the Issuing Banks and the Swingline Bank) agrees to reimburse the Agent promptly upon demand for such Bank’s Pro
        Rata Share of any reasonable costs and expenses (including, without limitation, reasonable counsel fees) incurred by the Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether
        through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, any of the Loan Documents or any other instrument or document furnished pursuant hereto or in connection herewith to the
        extent that the Agent is not reimbursed for such expenses by the Borrower and to the extent the same does not result from the Agent’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent
        jurisdiction.  In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.07 applies whether any such investigation, litigation or proceeding is brought by the Agent, any other Agent, any Bank or
        a third party.

    Section 7.08          Successor Agent.

    (a)          The Agent may resign at any time by giving written notice thereof to the Banks and the Borrower and may be removed at any time with or without cause by the Required Banks.  Upon any such resignation or removal, the Required Banks shall
        have the right to appoint a successor Agent which, if such successor Agent is not a Bank and no Event of Default shall have occurred and is continuing, is approved by the Borrower (which approval will not be unreasonably withheld).  If no successor
        Agent shall have been so appointed by the Required Banks (and, if not a Bank, approved by the Borrower), and shall have accepted such appointment, within 30 days after the retiring Agent’s giving of notice of resignation or the Required Banks’
        removal of the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a commercial bank organized or licensed under the laws of the United States of America or of any State thereof and having
        a combined capital and surplus of at least $500,000,000.  Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and
        duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents.  After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of
        this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

    
      69

      
        


    

    (b)          Any resignation by Citi as Agent pursuant to this Section 7.08 shall also constitute its resignation as the Swingline Bank and as an Issuing Bank.  Upon the acceptance of a successor’s appointment as Agent hereunder, (i) such successor
        shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Swingline Bank, and (ii) the retiring Swingline Bank shall be discharged from all of its duties and obligations hereunder or under the other
        Loan Documents.

    Section 7.09          Joint Lead Arrangers, Co-Syndication Agents and Co-Documentation Agents.  The Joint Lead Arrangers, Co-Syndication Agents and Co-Documentation
        Agents shall have no duties, obligations or liabilities hereunder or in connection herewith.

    Section 7.10          Defaulting Bank Provisions.  Anything herein to the contrary notwithstanding, if at any time the Required Banks determine that the Person serving
        as Agent is (without taking into account any provision in the definition of “Defaulting Bank” requiring notice from the Agent or any other party) a Defaulting Bank pursuant to clause (iv) of the definition thereof, the Required Banks (determined
        after giving effect to Section 8.01) may by notice to the Borrower and such Person remove such Person as Agent and, in consultation with the Borrower, appoint a replacement Agent hereunder.  Such removal will, to the fullest extent permitted by
        applicable law, be effective on the earlier of (a) the date a replacement Agent is appointed and (b) the date 30 days after the giving of such notice by the Required Banks (regardless of whether a replacement Agent has been appointed).

    ARTICLE VIII

        

        MISCELLANEOUS

    Section 8.01          Amendments, Etc.

    (a)          No amendment or waiver of any provision of this Agreement or any Note, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Required Banks, and then
        such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, however, that no such amendment, waiver or consent shall:  (i) waive any of the conditions specified in Section 3.01 without the written consent of each Bank, (ii) increase or
        extend the term of the Commitment of any Bank without the written consent of such Bank (it being understood that a waiver of any condition precedent in Section 3.02 or the waiver of any Default shall not constitute an increase or extension of any
        Commitment of any Bank), (iii) reduce the principal of, or the stated rate of interest on, the Advances or any fees or other amounts payable hereunder, without the written consent of each Bank affected thereby, (iv) postpone any date fixed for any
        payment of principal of, or interest on, the Advances or any fees or other amounts payable hereunder without the written consent of each Bank affected thereby, (v) amend the definition of “Required Banks”, or the percentage of the Advances or of
        the Revolving Credit Commitments, or the number or percentage of Banks, that shall be required for the Banks or any of them to take or approve, or direct the Agent to take, any action hereunder or under any other Loan Document, without the written
        consent of each Bank or (vi) amend the definition of “Pro Rata Share”, Section 2.14 or this Section 8.01 without the written consent of each Bank; and provided further that (w) no amendment, waiver or consent shall, unless in 

    
      70

      
        


    

    writing and signed by the Agent in addition to the Banks required above to take such action, affect the rights
        or duties of the Agent under this Agreement or any of the Notes, (x) no amendment, waiver or consent shall, unless in writing and signed by each Issuing Bank in addition to the Banks required above to take such action, affect the rights or
        obligations of any Issuing Bank under this Agreement, (y) no amendment, waiver or consent shall, unless in writing and signed by the Swingline Bank in addition to the Banks required above to take such action, affect the rights or duties of the
        Swingline Bank under this Agreement or any of the Notes and (z) the Borrower and the Agent may enter into amendments implementing LIBOR Successor Rate Conforming Changes in accordance with the terms of Section 2.09(g).

    (b)          Anything herein to the contrary notwithstanding, during such period as a Bank is a Defaulting Bank, to the fullest extent permitted by applicable law, such Bank will not be entitled to vote in respect of amendments and waivers hereunder
        and the Commitment and the outstanding Advances or other extensions of credit of such Bank hereunder will not be taken into account in determining whether the Required Banks or all of the Banks, as required, have approved any such amendment or
        waiver (and the definition of “Required Banks” will automatically be deemed modified accordingly for the duration of such period); provided that any such
        amendment or waiver that would increase or extend the term of the Commitment of such Defaulting Bank, extend the date fixed for the payment of principal or interest owing to such Defaulting Bank hereunder, reduce the principal amount of any
        obligation owing to such Defaulting Bank, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Bank or of any fee payable to such Defaulting Bank hereunder, or alter the terms of this proviso, will require
        the consent of such Defaulting Bank.

    (c)          Anything herein to the contrary notwithstanding, if the Agent and the Borrower shall have jointly identified an obvious error or an error or omission of a technical nature, in each case, in any provision of the Loan Documents, then the
        Agent and the Borrower shall be permitted to amend such provision, and, in each case, such amendment shall become effective without any further action or consent of any other party to any Loan Document if the same is not objected to in writing by
        the Required Banks to the Agent within five (5) Business Days following receipt of notice thereof.

    Section 8.02          Notices, Etc.  (a) Except as otherwise provided in Section 8.02(b) or in the proviso to this Section 8.02(a), all notices and other

    (but references herein to the address of the Agent for purposes of payments or making available funds or for purposes of
        Section 8.08(c) shall not include the address to which copies are to be sent); or, as to the Borrower, the Agent or the Swingline Bank, at such other address as shall be designated by such party in a written notice to the other parties and, as to
        each other party, at such other address as shall be designated by such party in a written notice to the Borrower and the Agent, provided that materials
        required to be delivered pursuant to Section 5.01(d)(i), (ii), (iii) or (vi), unless delivered by posting to a website as provided in Section 5.01(d), shall be delivered to the Agent as specified in Section 8.02(b) or as otherwise specified to the
        Borrower by the Agent.  Each such notice or communication shall be effective (A) if mailed, upon receipt, (B) if delivered by hand, upon delivery with written receipt, and (C) if telecopied, when sent (except that, if not given during normal
        business hours for the recipient, shall be deemed to have been given at the opening of business on the next business day for the recipient), except that any notice or communication to the Agent pursuant to this Agreement shall not be effective
        until actually received by the Agent.  Notices delivered through electronic communications to the extent provided in Section 8.02(b), shall be effective as provided in Section 8.02(b).

    (b)          Electronic Communications.  Notices and other communications to the Agent, the Banks, the Issuing Banks and the Swingline Bank hereunder may be
        delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Agent, provided
        that the foregoing shall not apply to notices to any Bank or Issuing Bank pursuant to Article II if such Bank or Issuing Bank, as applicable, has notified the Agent that it is incapable of receiving notices under such Article by electronic
        communication.  The Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided that approval of such procedures may be limited to particular notices or communications.

    Unless the Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address
        shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgement), provided that if such notice or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the
        opening of business on the next business day for the recipient, and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as
        described in the foregoing clause (i) of notification that such notice or communication is available and identifying the website address therefor.

    (c)          The Borrower hereby agrees that it will provide to the Agent all information, documents and other materials that it is obligated to furnish to the Agent pursuant to the Loan Documents, including, without limitation, all notices, requests,
        financial statements, financial and other reports, certificates and other information materials, but excluding any such communication that (i) relates to a request for a new, or a Conversion of an existing, Borrowing or other extension of credit
        (including any election of an interest rate or interest period relating thereto), (ii) relates to the payment of any principal or other amount due under this Agreement prior to the scheduled date therefor, (iii) provides notice of any Default or
        Event of Default, (iv) is required to be delivered to satisfy any condition precedent to the effectiveness of this Agreement and/or any Borrowing or other extension of credit hereunder or (v) is delivered by posting to a website as provided in
        Section 5.01(d) (all such non-excluded communications being referred to herein collectively as “Communications”), by transmitting the Communications in an
        electronic/soft medium in a format acceptable to the Agent to oploanswebadmin@citigroup.com.  In addition, the Borrower agrees to continue to provide the Communications to the Agent in the manner specified in the Loan Documents but only to the
        extent requested by the Agent.  The Borrower further agrees that the Agent may make the Communications available to the Banks by posting the Communications on Debtdomain, Intralinks or a substantially similar electronic transmission system (the “Platform”).  The Platform is provided “as is” and “as
          available”.  The Agent Parties (as defined below) do not warrant the accuracy or completeness of the Communications, or the adequacy of the Platform and expressly disclaim liability for errors or omissions in the Communications.  No warranty of
          any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third party rights or freedom from viruses or other code defects, is made by the Agent
          Parties in connection with the Communications or the Platform.  In no event shall the Agent or any of its Affiliates or any of their respective officers, directors, employees, agents, advisors or representatives (collectively, “Agent Parties”) have any liability to the
          Borrower, any Bank or any other Person or entity for damages of any kind, including, without limitation, direct or indirect, special, incidental or consequential damages, losses or expenses (whether in tort, contract or otherwise) arising out of
          the Borrower’s or the Agent’s transmission of Communications through the internet, except to the extent the liability of any Agent Party is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted primarily
          from such Agent Party’s gross negligence or willful misconduct.  The Agent agrees that the receipt of the Communications by the Agent at its e-mail address set forth above shall constitute effective delivery of the Communications to the
        Agent for purposes of the Loan Documents.

    The Borrower hereby acknowledges that certain of the Banks (each, a “Public Bank”) may have personnel who do not wish to receive material non-public information with respect to the Borrower or its Affiliates, or the respective securities of any of the foregoing, and who may
        be engaged in investment and other market-related activities with respect to such Persons’ securities.  The Borrower hereby agrees that (w) all materials that are to be made available to Public Banks (excluding (i) information delivered pursuant to
        Section 5.01(d)(i), (ii), (iii), (v) or (vi) and (ii) any information posted on the Borrower’s website or the Internet at www.halliburton.com, at sec.gov/edaux/searches.htm or at another website identified by the Borrower pursuant to Section 5.01
        (collectively, “Deemed Public Information”)) shall be clearly and conspicuously marked

    
      73

      
        


    

     “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof;
        (x) by marking such materials “PUBLIC,” the Borrower shall be deemed to have authorized the Agent, the Joint Lead Arrangers, the Issuing Banks and the Banks to treat such materials (and any Deemed Public Information) as not containing any material
        non-public information with respect to the Borrower or its securities for purposes of United States Federal and state securities laws (provided, however, that such materials shall be treated as set forth in Section 8.14); (y) all materials marked “PUBLIC”, together with all Deemed Public Information, are
        permitted to be made available through a portion of the Platform designated “Public Side Information;” and (z) the Agent and the Joint Lead Arrangers shall be entitled to treat any materials that are not marked “PUBLIC” (other than Deemed Public
        Information) as being suitable only for posting on a portion of the Platform not designated “Public Side Information.”

    (d)          Each Bank agrees that notice to it (as provided in the next sentence) (a “Notice”) specifying that any Communications have been posted to the
        Platform shall constitute effective delivery of such Communications to such Bank for purposes of this Agreement; provided that if requested by any Bank the
        Agent shall deliver a copy of the Communications to such Bank by email or facsimile.  Each Bank agrees (i) to notify the Agent in writing of such Bank’s e-mail address to which a Notice may be sent by electronic transmission (including by
        electronic communication) on or before the date such Bank becomes a party to this Agreement (and from time to time thereafter to ensure that the Agent has on record an effective e-mail address for such Bank) and (ii) that any Notice may be sent to
        such e-mail address.

    (e)          Nothing herein shall prejudice the right of the Agent or any Bank to give any notice or other communication pursuant to any Loan Document in any other manner specified in such Loan Document.

    Section 8.03          No Waiver; Remedies.  No failure on the part of any Bank or the Agent to exercise, and no delay in exercising, any right hereunder or under any
        Note shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the exercise of any other right.  The remedies herein provided are cumulative and not exclusive of
        any remedies provided by law.

    Notwithstanding anything to the contrary contained herein or in any other Loan Document, the
        authority to enforce rights and remedies hereunder and under the other Loan Documents against the Borrower shall be vested exclusively in, and all actions and proceedings at law in connection with such enforcement shall be instituted and maintained
        exclusively by, the Agent in accordance with Article VI for the benefit of all the Banks and the Issuing Banks; provided, however, that the foregoing shall not prohibit (a) the Agent from exercising on its own behalf the rights and remedies that inure to its benefit (solely in its capacity as Agent)
        hereunder and under the other Loan Documents, (b) any Issuing Bank or the Swingline Bank from exercising the rights and remedies that inure to its benefit (solely in its capacity as an Issuing Bank or Swingline Bank, as the case may be) hereunder
        and under the other Loan Documents, (c) any Bank from exercising setoff rights in accordance with Section 8.05 (subject to the terms of Section 2.14), or (d) any Bank from filing proofs of claim or appearing and filing pleadings on its own behalf
        during the pendency of a proceeding relative to the Borrower under any bankruptcy or insolvency law; and provided further that if at any time there is no Person acting as Agent hereunder and under the other Loan Documents, then (i) the Required Banks shall have the rights otherwise ascribed to the Agent
        pursuant to Article VI and (ii) in addition to the matters set forth in clauses (b), (c) and (d) of the preceding proviso and subject to Section 2.14, any Bank may, with the consent of the Required Banks, enforce any rights and remedies available
        to it and as authorized by the Required Banks.

    
      74

      
        


    

    Section 8.04          Expenses; Compensation.   (a) The Borrower agrees to pay on demand (i) all reasonable and documented out-of-pocket costs and expenses (including,
        without limitation, reasonable and documented fees and expenses of counsel) of the Joint Lead Arrangers and the Agent and each of their respective Affiliates in connection with the preparation, execution, delivery and administration of the Loan
        Documents and the other documents and instruments delivered hereunder or in connection with any amendments, modifications, consents or waivers in connection with the Loan Documents, (ii) all reasonable and documented fees and expenses of counsel
        for the Joint Lead Arrangers and the Agent and, during the existence of any Event of Default, any Bank with respect to advising any Joint Lead Arranger or the Agent or, during the existence of any Event of Default, any Bank as to its rights and
        responsibilities under the Loan Documents and (iii) all reasonable and documented out-of-pocket costs and expenses (including, without limitation, reasonable and documented fees and expenses of counsel) of the Joint Lead Arrangers, the Agent and
        each Bank in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of the Loan Documents (including the enforcement of rights under this Section 8.04(a)) and the other documents and instruments delivered
        hereunder and rights and remedies hereunder and thereunder.

    (b)          If any payment or purchase of principal of, or Conversion of, any Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance, as a result of a payment, purchase or Conversion pursuant to
        Section 2.09, Section 2.10, Section 2.15, Section 2.16, Section 2.17 or Section 2.23(c), acceleration of the maturity of the Advances pursuant to Section 6.01 or for any other reason, or if the Borrower, for any reason other than as provided in
        Section 2.02(c), fails to borrow or continue, or Convert any Base Rate Advance into, a Eurodollar Rate Advance, the Borrower shall, within 15 days after demand by any Bank (with a copy of such demand to the Agent), pay to the Agent for the account
        of such Bank any amounts required to compensate such Bank for any additional losses, costs or expenses which it may reasonably incur as a result of such payment, purchase or Conversion, or such failure to borrow, continue or Convert, including,
        without limitation, any loss (excluding loss of anticipated profits), cost or expense reasonably incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Bank to fund or maintain such Advance.  A certificate
        as to the amount of such additional losses, costs or expenses, submitted to the Borrower and the Agent by such Bank, shall be conclusive and binding for all purposes, absent manifest error.

    (c)          The Borrower agrees to indemnify and hold harmless the Agent, each Joint Lead Arranger, each Bank, each Issuing Bank, each Co-Syndication Agent, each Co-Documentation Agent and each of their
        respective Affiliates and each of their respective officers, directors, employees, agents, advisors and representatives (each, an “Indemnified Person”) from
        and against (and will promptly reimburse each Indemnified Person as the same are incurred for) any and all claims, damages, losses, liabilities and expenses (including, without limitation, the reasonable and documented fees, disbursements and other
        charges of one counsel for all Indemnified Persons selected by the Joint Lead Arrangers and one local counsel in each relevant jurisdiction (and one additional counsel to each group of affected Indemnified Persons that are similarly situated to the
        extent such Indemnified Persons reasonably conclude that

    
      75

      
        


    

     their interests conflict with those of any other Indemnified Person, and one local counsel
        in each relevant jurisdiction)), joint or several, that may be incurred by or asserted or awarded against any Indemnified Person (including, without limitation, in connection with any investigation, litigation or proceeding (a “Proceeding”) or the preparation of a defense in connection therewith), in each case arising out of or in connection with (i) this Agreement or any other
        Loan Document or the transactions contemplated hereby or thereby, (ii) any use made or proposed to be made with the proceeds of any Advance or any Letter of Credit or (iii) the existence of any condition on any property of the Borrower or any of
        its Subsidiaries that constitutes a violation of any environmental protection law or any other law, rule, regulation or order, except to the extent such claim, damage, loss, liability or expense (i) is found in a final, non-appealable judgment by a
        court of competent jurisdiction to have resulted from the gross negligence, bad faith or willful misconduct of such Indemnified Person, (ii) arises from a material breach of such Indemnified Person’s obligations hereunder as determined in a final,
        non-appealable judgment by a court of competent jurisdiction or (iii) arises from a Proceeding by an Indemnified Person against another Indemnified Person (other than a Proceeding involving (A) alleged conduct by the Borrower or any of its
        Affiliates or (B) against an arranger, bookrunner or administrative agent in its capacity as such).

    In the case of a Proceeding to which the indemnity in this Section 8.04(c) applies,
        such indemnity shall be effective, whether or not such Proceeding is brought by the Borrower or any of its Affiliates, securityholders or creditors, an Indemnified Person or any other person, or an Indemnified Person is otherwise a party thereto
        and whether or not the transactions contemplated hereby are consummated.

    No Indemnified Person shall have any liability (whether direct or indirect, in
        contract, tort or otherwise) to the Borrower or any of its Affiliates, securityholders or creditors for or in connection with the transactions contemplated hereby, except to the extent such liability is found in a final non-appealable judgment by a
        court of competent jurisdiction to have resulted from such Indemnified Person’s (i) gross negligence, bad faith or willful misconduct or (ii) a material breach of such Indemnified Person’s obligations hereunder.  In no event, however, shall any
        Indemnified Person be liable for any special, indirect, consequential or punitive damages (including, without limitation, any loss of profits, business or anticipated savings).  No Indemnified Person shall be liable for any damages arising from the
        use by unintended recipients of any information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

    The Borrower shall not, without the prior written consent of an Indemnified Person
        (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened Proceeding against an Indemnified Person in respect of which indemnity could have been sought hereunder by such Indemnified Person unless such
        settlement (i) includes an unconditional release of such Indemnified Person from all liability or claims that are the subject matter of such Proceeding, (ii) does not include any statement as to any admission by or on behalf of such Indemnified
        Person (it being understood that an Indemnified Person may reasonably withhold its consent to any settlement that does not comply with 

    
      76

      
        


    

    clauses (i) and (ii) of this sentence) and (iii) is in writing in form reasonably
        acceptable to the applicable Indemnified Persons.  Each Indemnified Person will promptly notify the Borrower upon receipt of written notice of any claim or threat to institute a claim, provided that any failure by any Indemnified Person to give such notice shall not relieve the Borrower from the obligation to indemnify the Indemnified Persons to the extent that the Borrower is not materially
        prejudiced as a result of such failure.

    Payments under any indemnification provided for in this Section 8.04(c) shall be made within 30 days
        from the date such Indemnified Person makes written demand therefor.

    (d)          Section 8.04(a)-(c) shall not apply to taxes which shall be governed solely by Sections 2.12 and 2.13.

    (e)          Without prejudice to the survival of any other agreement of the Borrower hereunder, all obligations of the Borrower under Section 2.12, Section 2.13 and this Section 8.04 shall survive the termination of the Commitments and this Agreement
        and the payment in full of all amounts hereunder and under the Notes.

    Section 8.05          Right of Set-Off.  Upon (a) the occurrence and during the continuance of any Event of Default and (b) the making by the Required Banks of the
        request or the granting by the Required Banks of the consent specified by Section 6.01 to authorize the Agent to declare the Advances due and payable pursuant to the provisions of Section 6.01, each Bank is hereby authorized at any time and from
        time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Bank (or by any branch,
        agency, subsidiary or other Affiliate of such Bank, wherever located) 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 this Agreement or any Note held by such
        Bank, whether or not such Bank shall have made any demand under this Agreement or any such Note and although such obligations may be unmatured.  Each Bank agrees promptly to notify the Administrative Agent and the Borrower after any such set-off
        and application made by such Bank, provided that the failure to give such notice shall not affect the validity of such set-off and application.  The rights
        of each Bank under this Section 8.05 are in addition to other rights and remedies (including, without limitation, other rights of setoff) which such Bank may have.

    Section 8.06          Limitation and Adjustment of Interest.   (a) Notwithstanding anything to the contrary set forth herein, in any other Loan Document or in any
        other document or instrument, no provision of any of the Loan Documents or any other instrument or document furnished pursuant hereto or in connection herewith is intended or shall be construed to require the payment or permit the collection of
        interest in excess of the maximum non-usurious rate permitted by applicable law.  Accordingly, if the transactions with any Bank contemplated hereby would be usurious under applicable law, if any, then, in that event, notwithstanding anything to
        the contrary in any Note payable to such Bank, this Agreement or any other document or instrument, it is agreed as follows:  (i) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken,
        reserved, charged or received by such Bank under any Note payable to such Bank, this Agreement or any other document or instrument shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be
        canceled automatically and, if theretofore paid, shall, at the option of such Bank, be credited by such Bank on the principal amount of the indebtedness owed to such Bank by the Borrower or refunded by such Bank to the Borrower, and (ii) in the
        event that the maturity of any Note payable to such Bank is accelerated or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to such Bank may never include more than the
        maximum amount allowed by such applicable law and excess interest, if any, to such Bank provided for in this Agreement or otherwise shall be canceled automatically as of 

    
      77

      
        


    

    the date of such acceleration or prepayment and, if theretofore paid, shall, at the option of such Bank, be credited by such Bank on
        the principal amount of the indebtedness owed to such Bank by the Borrower or refunded by such Bank to the Borrower.  In determining whether or not the interest contracted for, taken, reserved, charged or received by any Bank exceeds the maximum
        non-usurious rate permitted by applicable law, such determination shall be made, to the extent that doing so does not result in a violation of applicable law, by amortizing, prorating, allocating and spreading, in equal parts during the period of
        the full stated term of the loans hereunder, all interest at any time contracted for, taken, charged, received or reserved by such Bank in connection with such loans.

    (b)          In the event that at any time the interest rate applicable to any Advance made by any Bank would exceed the maximum non-usurious rate allowed by applicable law, the rate of interest to accrue on the Advances by such Bank shall be limited
        to the maximum non-usurious rate allowed by applicable law, but shall accrue, to the extent permitted by law, on the principal amount of the Advances made by such Bank from time to time outstanding, if any, at the maximum non-usurious rate allowed
        by applicable law until the total amount of interest accrued on the Advances made by such Bank equals the amount of interest which would have accrued if the interest rates applicable to the Advances pursuant to Article II had at all times been in
        effect.  In the event that upon the final payment of the Advances made by any Bank and termination of the Revolving Credit Commitment of such Bank, the total amount of interest paid to such Bank hereunder and under the Notes is less than the total
        amount of interest which would have accrued if the interest rates applicable to such Advances pursuant to Article II had at all times been in effect, then the Borrower agrees to pay to such Bank, to the extent permitted by law, an amount equal to
        the excess of (i) the lesser of (A) the amount of interest which would have accrued on such Advances if the maximum non-usurious rate allowed by applicable law had at all times been in effect or (B) the amount of interest which would have accrued
        on such Advances if the interest rates applicable to such Advances pursuant to Article II had at all times been in effect over (ii) the amount of interest otherwise accrued on such Advances in accordance with this Agreement.

    Section 8.07          Binding Effect.  This Agreement shall become effective as provided in Section 3.01 and thereafter shall be binding upon and inure to the benefit
        of the Borrower and the Agent and each Bank and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights or obligations hereunder or under any other Loan Document or any interest herein or
        therein without the prior written consent of all of the Banks (and any attempted assignment without such consent shall be null and void).

    Section 8.08          Assignments and Participations.  (a) Each Bank may assign to one or more banks or other entities all or a portion of its rights and obligations
        under this Agreement (including, without limitation, all or a portion of its Commitment, the Advances owing to it and the Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, 

    
      78

      
        


    

    percentage of all rights and obligations under this Agreement, (ii) except in the case of an assignment of all of a Bank’s rights and
        obligations under this Agreement, the amount of the Commitment of the assigning Bank being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance with respect to such assignment) shall in no event be
        less than $5,000,000, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance,
        together with the Notes subject to such assignment and a processing and recordation fee of $3,500.  Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Assignment and Acceptance, (x) the
        assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Bank hereunder and (y) the Bank assignor
        thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an
        Assignment and Acceptance covering all of an assigning Bank’s rights and obligations under this Agreement, such Bank shall cease to be a party hereto) except that the rights of the assigning Bank under Sections 2.08, 2.12, 2.13 and 8.04 shall
        continue with respect to events and occurrences occurring before or concurrently with the effective date of such Assignment and Acceptance.

    (b)          By executing and delivering an Assignment and Acceptance, the Bank assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows:  (i) other than as provided in such
        Assignment and Acceptance, such assigning Bank makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or any other instrument
        or document furnished pursuant hereto or in connection herewith or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or document furnished pursuant hereto or in
        connection herewith; (ii) such assigning Bank makes no representation or warranty and assumes no responsibility with respect to the financial condition of the Borrower or any other Person or the performance or observance by the Borrower or any
        other Person of any of its respective obligations under any Loan Document or any other instrument or document furnished pursuant hereto or in connection herewith; (iii) such assignee confirms that it has received a copy of this Agreement, together
        with copies of the most recent financial statements delivered pursuant to Section 5.01(d)(i) and (ii) and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment
        and Acceptance; (iv) such assignee will, independently and without reliance upon the Agent, such assigning Bank or any other Bank and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit
        decisions in taking or not taking action under this Agreement, any of the other Loan Documents or any other instrument or document; (v) such assignee confirms that it is an Eligible Assignee; (vi) such assignee appoints and authorizes the Agent to
        take such action as Agent on its behalf and to exercise such powers and discretion under the Loan Documents as are delegated to the Agent by the terms hereof or thereof, together with such powers and discretion as are reasonably incidental thereto;
        and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Bank.

    
      79

      
        


    

    (c)          The Agent shall maintain at its address referred to in Section 8.02 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Banks and the Commitment of,
        and the principal amount of the Revolving Credit Advances owing to, each Bank from time to time (the “Register”).  The entries in the Register shall be
        conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Banks may treat each Person whose name is recorded in the Register as a Bank hereunder for all purposes of this Agreement.  The Register shall be
        available for inspection by the Borrower or any Bank at any reasonable time and from time to time upon reasonable prior notice.

    (d)          Upon its receipt of an Assignment and Acceptance executed by an assigning Bank and an assignee representing that it is an Eligible Assignee, together with the Notes, if any, subject to such assignment, the Agent shall, if such Assignment
        and Acceptance has been completed and is in substantially the form of Exhibit D, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrower.  Within
        five (5) Business Days after its receipt of such notice, the Borrower shall execute and deliver to the Agent in exchange for the surrendered Notes, if any, a new Note (if requested by the assignee) payable to the order of such Eligible Assignee in
        an amount equal to the Revolving Credit Commitment assumed by it pursuant to such Assignment and Acceptance (plus any Revolving Credit Commitment already held by it) and, if the assigning Bank has retained a Revolving Credit Commitment hereunder, a
        new Note payable to the order of the assigning Bank in an amount equal to the Revolving Credit Commitment retained by it hereunder (such new Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered
        Notes, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in substantially the form of Exhibit A-1).

    (e)          Each Bank may sell participations to one or more banks or other entities (other than the Borrower or any of its Affiliates) in or to all or a portion of its rights and obligations under this Agreement (including, without limitation, all
        or a portion of its Commitment, the Advances owing to it and the Notes held by it) (each such recipient of a participation, a “Participant”); provided, however, that (i) such Bank’s obligations under this
        Agreement (including, without limitation, its Commitment to the Borrower hereunder) shall remain unchanged, (ii) such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Bank shall
        remain the holder of any such Notes for all purposes of this Agreement, (iv) the Borrower, the Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under this
        Agreement, and (v) the terms of any such participation shall not restrict such Bank’s ability to make any amendment or waiver of this Agreement or any Note or such Bank’s ability to consent to any departure by the Borrower therefrom without the
        approval of the Participant, except that the approval of the Participant may be required to the extent that such amendment, waiver or consent would reduce the principal of, or interest on, the Notes or any fees or other amounts payable hereunder,
        in each case to the extent subject to such participation, or postpone any date fixed for any payment of principal of or interest on, the Notes or any fees or other amounts payable hereunder, in each case to the extent subject to such
        participation.  Each Bank that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and
        stated interest) of each Participant’s interest in Advances or other Obligations under the 

    
      80

      
        


    

    Loan Documents (the “Participant


            Register”); provided that no Bank shall have any obligation to disclose all or any portion of the Participant Register (including the
        identity of any Participant or any information relating to a Participant’s interest in any Commitments, Advances, Letters of Credit or other Obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary
        to establish that such Commitment, Advance, Letter of Credit or other Obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations.  The entries in the Participant Register shall be conclusive absent manifest
        error, and such Bank shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.  For the avoidance of doubt, the
        Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

    (f)          Each Issuing Bank may assign to an Eligible Assignee all or a portion of its rights and obligations under the undrawn portion of its Letter of Credit Commitment at any time; provided, however, that (i) each such assignment shall be to an Eligible Assignee and (ii) the parties to each such
        assignment shall execute and deliver to the Agent, for its acceptance and recording in the Register, an Assignment and Acceptance, together with a processing and recordation fee of $3,500.

    (g)          Any Bank may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 8.08, disclose to the assignee or participant or proposed assignee or participant, any information relating
        to the Borrower or any of its Subsidiaries furnished to such Bank by or on behalf of the Borrower or any of its Subsidiaries; provided that, prior to any
        such disclosure, the assignee or participant or proposed assignee or participant shall agree to comply with Section 8.14.

    (h)          Notwithstanding any other provision set forth in this Agreement, any Bank may at any time create a pledge or security interest in all or any portion of its rights under this Agreement (including, without limitation, the Revolving Credit
        Advances owing to it and the Note or Notes held by it) to secure obligations of such Bank, including any pledge in favor of any Federal Reserve Bank in accordance with Regulation A of the Federal Reserve Board; provided that no such pledge or security interest shall release such Bank from any of its obligations hereunder or substitute any pledgee or secured party for such Bank as a party
        hereto.

    Section 8.09          No Liability of Issuing Banks.  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 any Issuing Bank nor any other Bank nor any of its employees, Affiliates, advisors, attorneys, agents, 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 such 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 such 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 such Issuing Bank, and such 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) such Issuing Bank’s willful misconduct or gross negligence as determined in a final,
        non-appealable 

    
      81

      
        


    

    judgment by a court of competent jurisdiction in determining whether documents presented under any Letter of Credit comply with the
        terms of such Letter of Credit or (ii) such 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, an 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          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 a copy of a signature page to this Agreement by facsimile or other electronic
        communication (e-mail) shall be as effective as delivery of a manually executed counterpart of this Agreement.

    Section 8.11          Judgment.  (a) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in Dollars into another
        currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Agent could purchase Dollars with such other currency
        at Citi’s principal office in London at 11:00 A.M. (London time) on the Business Day preceding that on which final judgment is given.

    (b)          If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in a Foreign Currency into Dollars, the parties agree to the fullest extent that they may effectively do so, that the rate of exchange
        used shall be that at which in accordance with normal banking procedures the Agent could purchase such Foreign Currency with Dollars at Citi’s principal office in London at 11:00 A.M. (London time) on the Business Day preceding that on which final
        judgment is given.

    (c)          The obligation of the Borrower in respect of any sum due from it in any currency (the “Primary Currency”) to any Bank or the Agent hereunder shall,
        notwithstanding any judgment in any other currency, be discharged only to the extent that on the Business Day following receipt by such Bank or the Agent (as the case may be), of any sum adjudged to be so due in such other currency, such Bank or
        the Agent (as the case may be) may in accordance with normal banking procedures purchase the applicable Primary Currency with such other currency; if the amount of the applicable Primary Currency so purchased is less than such sum due to such Bank
        or the Agent (as the case may be) in the applicable Primary Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Bank or the Agent (as the case may be) against such loss, and if the amount
        of the applicable Primary Currency so purchased exceeds such sum due to any Bank or the Agent (as the case may be) in the applicable Primary Currency, such Bank or the Agent (as the case may be) agrees to remit to the Borrower such excess.

    
      82

      
        


    

    Section 8.12          Governing Law.  This Agreement and the Notes shall be governed by, and construed in accordance with, the laws of the State of New York.

    Section 8.13          Jurisdiction; Damages.  To the fullest extent it may effectively do so under applicable law, (a) each of the parties hereto hereby irrevocably

        of or relating to this Agreement, any of the Notes, or any other instrument or document furnished pursuant hereto or in connection herewith or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and
        unconditionally agrees that all claims in respect of such action or proceeding may be heard and determined in any such court; (b) each of the parties hereto hereby irrevocably and unconditionally waives the defense of an inconvenient forum to the
        maintenance of such action or proceeding and any objection that it may now or hereafter have to the laying of venue of any such action or proceeding in any such court; (c) the Borrower hereby agrees that service of copies of the summons and
        complaint and any other process which may be served in any such action or proceeding may be made by mailing or delivering a copy of such process to the Borrower at its address specified in Section 8.02; and (d) each of the parties hereto agrees
        that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.  Nothing herein shall affect the rights of any Bank or the Agent
        to serve legal process in any other manner permitted by law.  Each of the Borrower, the Agent and the Banks and each of their respective directors, officers, employees, Affiliates, advisors and agents hereby irrevocably and unconditionally waives,
        to the fullest extent it may effectively do so under applicable law, any right it may have to claim or recover in any action or proceeding referred to in this Section 8.13 any special, indirect, consequential, punitive, treble or exemplary damages;
        provided that nothing in this Section 8.13 shall limit the Borrower’s indemnification obligations to the extent such special, indirect, consequential,
        punitive, treble or exemplary damages are included in any third party claim in connection with which an Indemnified Person is entitled to indemnification hereunder.

    Section 8.14          Confidentiality.  Each Bank agrees that it will maintain the confidentiality of, and will not to disclose without the prior consent of the

        by the Borrower; provided that any Bank may disclose any such information (i) to the extent that such information becomes publicly available other than by
        reason of disclosure in violation of this Agreement by the Banks, (ii) as may be required or appropriate in any report, statement or testimony submitted to or required by any municipal, state or Federal regulatory body having or claiming to have
        jurisdiction over any Bank or its Affiliates or submitted to or required by the Federal Reserve Board or the Federal Deposit Insurance Corporation or similar organizations (whether in the United States or elsewhere) or their successors, and
        including any self-regulatory body having or claiming authority to regulate or oversee any aspect of any Bank’s or its Affiliates’ businesses, (iii) as may be required or appropriate in response to any summons or subpoena in connection with any

        extent that such information is received by such Bank from a third party that is not to such Bank’s knowledge subject to confidentiality obligations to the Borrower, (xi) to the extent that such information is independently developed by the Banks
        and (xii) on a confidential basis to (A) any rating agency in connection with rating the Borrower or its Subsidiaries or the facility evidenced by this Agreement or (B) the CUSIP Service Bureau or any similar agency in connection with the issuance

    Section 8.15          Patriot Act Notice.  Each Bank and the Agent (for itself and not on behalf of any Bank) hereby notifies the Borrower that, pursuant to the
        requirements of the Patriot Act and/or the Beneficial Ownership Regulation, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information

    ANNEX A

    “Applicable
            Commitment Fee Rate” means, for any date, the rate per annum set forth in the table below under the heading “Applicable Commitment Fee Rate” opposite the debt rating from S&P and Moody’s, respectively, in effect on such date for
        the senior unsecured long-term debt of the Borrower, with the higher of the two ratings to be determinative in the case where the ratings from S&P and Moody’s would result in different Applicable Commitment Fee Rates; provided that if the debt rating from one of the Rating Agencies is more than one level below the debt rating from the other Rating Agency, then the debt rating one level below
        the higher of the two shall be used in determining the Applicable Commitment Fee Rate; provided further that (i) if only one Rating Agency has a rating in effect on such date for the senior unsecured long-term debt of the Borrower, then only such rating shall be used in determining the Applicable
        Commitment Fee Rate, and (ii) if neither Rating Agency has a rating in effect on such date for the senior unsecured long-term debt of the Borrower, then the lowest level (i.e., highest Applicable Commitment Fee Rate) shall be used in determining
        the Applicable Commitment Fee Rate:

        the heading “Eurodollar Rate Advances” and (b) with respect to Base Rate Advances, the rate per annum set forth in the table below under the heading “Base Rate Advances”, in each case, opposite the debt rating from S&P and Moody’s,
        respectively, in effect on such date for the senior unsecured long-term debt of the Borrower, with the higher of the two ratings to be determinative in the case where the ratings from S&P and Moody’s would result in different Applicable
        Margins; provided that if the debt rating from one of the Rating Agencies is more than one level below the debt rating from the other Rating Agency, then
        the debt rating one level below the higher of the two shall be used in determining the Applicable Margin; provided further that (i) if only one Rating Agency has a rating in effect on such date for the senior unsecured long-term debt of the Borrower, then only such rating shall be used in
        determining the Applicable Margin, and (ii) if neither Rating Agency has a rating in effect on such date for the senior unsecured long-term debt of the Borrower, then the lowest level (i.e., highest Applicable Margin) shall be used in determining
