Revolving Commitment of such Lender at such time.

Revolving Facility that consist of Eurodollar Loans, each such Borrowing shall have a different initial Interest Period; (ii) only one Borrowing under the Swing Line Revolving Facility may be made on any single day; and (iii) at no time shall there
be more than an aggregate of 8 Borrowings under the General Revolving Facility and the Swing Line Revolving Facility. 
  
 (b) All Borrowings under a Facility shall be made by the Lenders having Commitments under such Facility pro rata on the basis
of their respective Commitments under such Facility. It is understood that no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender shall be obligated to make the Loans
provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its Commitment hereunder. 
  
 2.3. Procedures for Borrowing. (a) Notice of Borrowing. Whenever the Borrower desires to incur Loans, it shall give the Administrative Agent
at its Notice Office: 
  
 (A)
Borrowings of Prime Rate Loans under the General Revolving Facility: in the case of any Borrowing under the General Revolving Facility of Prime Rate Loans to be made hereunder, prior to 12:00 noon (local time at its Notice Office), at least one
Business Day’s prior written or telephonic notice thereof (in the case of telephonic notice, promptly confirmed in writing); or 
  
 (B) Borrowings of Eurodollar Loans under the General Revolving Facility Denominated in Dollars: in the case of any Borrowing
under the General Revolving Facility of Eurodollar Loans denominated in Dollars to be made hereunder, prior to 12:00 noon (local time at its Notice Office), at least three Business Days’ prior written or telephonic notice thereof (in the case

denominated in an Alternative Currency to be made hereunder, prior to 12:00 noon (local time at its Notice Office), at least five Business Days’ prior written or telephonic notice thereof (in the case of telephonic notice, promptly confirmed in
writing); or 
  
 (D) Borrowings under
the Swing Line Revolving Facility: in the case of any Borrowing under the Swing Line Revolving Facility of a Prime Rate Loan or a Eurodollar Market 

  

 - 24 - 








 
Index Rate Loan, prior to 1:00 P.M. (local time at its Notice Office), on the proposed date of Borrowing, written or telephonic notice thereof (in the case
of telephonic notice, promptly confirmed in writing if so requested by the Administrative Agent). 
  
 Each such notice (each such notice, a “Notice of Borrowing”) shall (in the case of Swing Line Revolving Loans, if requested by the Administrative Agent to be confirmed in writing), be
substantially in the form of Exhibit B-1, and in any event shall be irrevocable and shall specify: (i) the Facility under which the Borrowing is to be incurred; (ii) the aggregate principal amount of the Loans to be made pursuant to such Borrowing;
(iii) the date of the Borrowing (which shall be a Business Day); (iv) whether the Borrowing shall consist of Prime Rate Loans, Eurodollar Loans or Eurodollar Market Index Rate Loans; and (v) if the requested Borrowing consists of Eurodollar Loans,
(A) the currency, if other than Dollars, in which such Loans are requested and (B) the Interest Period to be initially applicable thereto. If the Borrower fails to specify in a Notice of Borrowing the Interest Period and currency for any Eurodollar
Loans, such Interest Period shall be deemed to be one month and such currency Dollars. The Administrative Agent shall promptly give each Lender that has a Commitment under any applicable Facility written notice (or telephonic notice promptly
confirmed in writing) of each proposed Borrowing under the applicable Facility, of such Lender’s proportionate share thereof and of the other matters covered by the Notice of Borrowing relating thereto. 
  
 (b) Borrowings of Eurodollar Loans Denominated in an Alternative
Currency. In the case of a proposed Borrowing comprised of Loans that are Eurodollar Loans denominated in an Alternative Currency, the obligation of each affected Lender to make its Eurodollar Loan in the requested Alternative Currency as part
of such Borrowing is subject to: 
  
 (A) if such requested Alternative Currency is an Alternative Currency described in clause (i) of the definition of the term Alternative Currency, the confirmation by the Administrative Agent to the Borrower not later than the
fourth Business Day before the requested date of such Borrowing that such Alternative Currency is readily and freely transferable and convertible into Dollars, or 
  
 (B) if such requested Alternative Currency is not an Alternative Currency described in clause
(i) of the definition of the term Alternative Currency, the confirmation by such Lender to the Administrative Agent not later than the fourth Business Day before the requested date of such Borrowing that such Alternative Currency is acceptable to
such Lender, which confirmation shall be notified immediately by the Administrative Agent to the Borrower. 
  
 If the Administrative Agent shall not have provided the confirmation referred to in clause (A) above, or any affected Lender shall not have so provided to the Administrative Agent the confirmation referred to in
clause (B) above, the Administrative Agent shall promptly notify the Borrower and each affected Lender that a Lender has not provided any such confirmation referred to in such clause (B), whereupon the Borrower may, by notice to the Administrative
Agent not later than the third Business Day before the requested date of such Borrowing, withdraw the Notice of Borrowing relating to such requested Borrowing. If the Borrower does so withdraw such Notice of Borrowing, the Borrowing requested in
such Notice of Borrowing shall not occur and the Administrative Agent shall promptly so notify each affected Lender. If the Borrower does not so withdraw such Notice of Borrowing, the Administrative Agent shall promptly so notify each affected
Lender and such Notice of Borrowing shall be deemed to be a Notice of Borrowing that requests a Borrowing of Loans comprised of Eurodollar Loans in an aggregate amount in Dollars equivalent, on the date the Administrative Agent so notifies each
affected Lender, to the amount of the originally requested Borrowing in an Alternative Currency; and in such notice by the Administrative Agent to each affected Lender the Administrative Agent shall state such aggregate equivalent amount of such
Borrowing in Dollars and such Lender’s ratable portion of such Borrowing. 
  

 - 25 - 








 (c) Actions by Administrative Agent on Telephonic Notice. Without in any way limiting the
obligation of the Borrower to confirm in writing any telephonic notice permitted to be given hereunder, the Administrative Agent may act prior to receipt of written confirmation without liability upon the basis of such telephonic notice believed by
the Administrative Agent in good faith to be from an Authorized Officer of the Borrower entitled to give telephonic notices under this Agreement on behalf of the Borrower. In each such case, the Administrative Agent’s record of the terms of
such telephonic notice shall be conclusive absent manifest error. 
  
 2.4. Disbursement of Funds. (a) No later than 2:00 P.M. (local time at the Payment Office) on the date specified in each Notice of Borrowing, each Lender with a Commitment under the Facility under which any Borrowing pursuant
to such Notice of Borrowing is to be made will make available its pro rata share, if any, of each Borrowing under such Facility requested to be made on such date in the manner provided below. All amounts shall be made available to the
Administrative Agent in U.S. dollars or the applicable Alternative Currency and immediately available funds at the Payment Office and the Administrative Agent promptly will make available to the Borrower by depositing to its account at the Payment
Office the aggregate of the amounts so made available in the type of funds received. Unless the Administrative Agent shall have been notified by any Lender prior to the date of Borrowing that such Lender does not intend to make available to the
Administrative Agent its portion of the Borrowing or Borrowings to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the
Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the
Administrative Agent by such Lender and the Administrative Agent has made available same to the Borrower, the Administrative Agent shall be entitled to recover such corresponding amount from such Lender. If such Lender does not pay such
corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Administrative Agent. The
Administrative Agent shall also be entitled to recover from such Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the
Administrative Agent to the Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (x) if paid by such Lender, the overnight Federal Funds Effective Rate, in the case of any Loan
denominated in Dollars, or at the weighted average overnight or weekend borrowing rate for immediately available and freely transferable funds in the applicable Alternative Currency that is offered to the Administrative Agent in the international
markets, in the case of any Loan denominated in an Alternative Currency, or (y) if paid by the Borrower, the then applicable rate of interest, calculated in accordance with section 2.8, for the respective Loans (but without any requirement to pay
any amounts in respect thereof pursuant to section 2.11). 
  
 (b) Nothing herein and no subsequent termination of the Commitments pursuant to section 5.1 or 5.2 shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder and in existence from time to
time or to prejudice any rights that the Borrower may have against any Lender as a result of any default by such Lender hereunder. 
  
 2.5. Refunding of, or Participation in, Swing Line Revolving Loans. (a) If any Event of Default exists, the Swing Line Lender
may, in its sole and absolute discretion, direct that the Swing Line Revolving Loans owing to it be refunded by delivering a notice to such effect to the Administrative Agent, specifying the aggregate principal amount thereof (a “Notice
of Swing Line Refunding”). Promptly upon receipt of a Notice of Swing Line Refunding, the Administrative Agent shall give notice of the contents thereof to the Lenders with General Revolving Commitments and, unless an Event of Default
specified in section 11.1(g) in respect of the Borrower has occurred, also to the Borrower. Each 

  

 - 26 - 








 
such Notice of Swing Line Refunding shall be deemed to constitute delivery by the Borrower of a Notice of Borrowing requesting General Revolving Loans
consisting of Prime Rate Loans in the amount of the Swing Line Revolving Loans to which it relates. Each Lender with a General Revolving Commitment (including the Swing Line Lender, in its capacity as a Lender) hereby unconditionally agrees
(notwithstanding that any of the conditions specified in section 7.2 hereof or elsewhere in this Agreement shall not have been satisfied, but subject to the provisions of paragraph (b) below) to make a General Revolving Loan to the Borrower in an
amount equal to such Lender’s General Revolving Facility Percentage of the aggregate amount of the Swing Line Revolving Loans to which such Notice of Swing Line Refunding relates. Each such Lender shall make the amount of such General Revolving
Loan available to the Administrative Agent in immediately available funds at the Payment Office not later than 2:00 P.M. (local time at the Payment Office), if such notice is received by such Lender prior to 11:00 A.M. (local time at its Domestic
Lending Office), or not later than 2:00 P.M. (local time at the Payment Office) on the next Business Day, if such notice is received by such Lender after such time. The proceeds of such General Revolving Loans shall be made immediately available to
the Swing Line Lender and applied by it to repay the principal amount of the Swing Line Revolving Loans to which such Notice of Swing Line Refunding related. The Borrower irrevocably and unconditionally agrees that, notwithstanding anything to the
contrary contained in this Agreement, General Revolving Loans made as herein provided in response to a Notice of Swing Line Refunding shall constitute General Revolving Loans hereunder consisting of Prime Rate Loans. 
  
 (b) If prior to the time a General Revolving Loan would
otherwise have been made as provided above as a consequence of a Notice of Swing Line Refunding, any of the events specified in section 11.1(g) shall have occurred in respect of the Borrower or one or more of the Lenders with General Revolving
Commitments shall determine that it is legally prohibited from making a General Revolving Loan under such circumstances, each Lender (other than the Swing Line Lender), or each Lender (other than the Swing Line Lender) so prohibited, as the case may
be, shall, on the date such General Revolving Loan would have been made by it (the “Purchase Date”), purchase an undivided participating interest in the outstanding Swing Line Revolving Loans to which such Notice of Swing
Line Refunding related, in an amount (the “Swing Line Participation Amount”) equal to such Lender’s General Revolving Facility Percentage of such Swing Line Revolving Loans. On the Purchase Date, each such Lender or each
such Lender so prohibited, as the case may be, shall pay to the Swing Line Lender, in immediately available funds, such Lender’s Swing Line Participation Amount, and promptly upon receipt thereof the Swing Line Lender shall, if requested by
such other Lender, deliver to such Lender a participation certificate, dated the date of the Swing Line Lender’s receipt of the funds from, and evidencing such Lender’s participating interest in such Swing Line Revolving Loans and its
Swing Line Participation Amount in respect thereof. If any amount required to be paid by a Lender to the Swing Line Lender pursuant to the above provisions in respect of any Swing Line Participation Amount is not paid on the date such payment is
due, such Lender shall pay to the Swing Line Lender on demand interest on the amount not so paid at the overnight Federal Funds Effective Rate from the due date until such amount is paid in full. 
  
 (c) Whenever, at any time after the Swing Line Lender has
received from any other Lender such Lender’s Swing Line Participation Amount, the Swing Line Lender receives any payment from or on behalf of the Borrower on account of the related Swing Line Revolving Loans, the Swing Line Lender will promptly
distribute to such Lender its General Revolving Facility Percentage of such payment on account of its Swing Line Participation Amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such
Lender’s participating interest was outstanding and funded); provided, however, that in the event such payment received by the Swing Line Lender is required to be returned, such Lender will return to the Swing Line Lender any
portion thereof previously distributed to it by the Swing Line Lender. 
  

 - 27 - 








 (d) Each Lender’s obligation to make General Revolving Loans and/or to purchase
participations in connection with a Notice of Swing Line Refunding (that shall in all events be within such Lender’s Unutilized General Revolving Commitment, taking into account all outstanding participations in connection with Swing Line
Refundings) shall be subject to the conditions that: 
  
 (i) such Lender shall have received a Notice of Swing Line Refunding complying with the provisions hereof, and 
  
 (ii) at the time the Swing Line Revolving Loans that are the subject of such Notice of Swing Line Refunding were made, the Swing Line
Lender had no actual written notice from another Lender that an Event of Default had occurred and was continuing, 
  
 but otherwise shall be absolute and unconditional, shall be solely for the benefit of the Swing Line Lender, and shall not be affected by any circumstance, including,
without limitation: (A) any set-off, counterclaim, recoupment, defense or other right that such Lender may have against any other Lender, the Borrower, or any other person, may have against any Lender or other person, as the case may be, for any
reason whatsoever; (B) the occurrence or continuance of a Default or Event of Default; (C) any event or circumstance involving a Material Adverse Effect upon the Borrower; (D) any breach of any Credit Document by any party thereto; or (E) any other
circumstance, happening or event, whether or not similar to any of the foregoing.

provided in section 2.8 in respect of Prime Rate Loans or Eurodollar Market Index Rate Loans, as the case may be; (vi) be subject to mandatory prepayment as provided in section 6.2; and (vii) be entitled to the benefits of this Agreement and the
other Credit Documents.

in which it shall record: (i) the amount of each Loan made hereunder, the Type thereof, the particular Facility under which such Loan was made, and the Interest Period or maturity date and applicable interest rate if such Loan is a Eurodollar Loan;
(ii) the amount of any principal due and payable or to become due and payable from the Borrower to each Lender hereunder; and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each
Lender’s share thereof. 
  
 (f) Effect of Loan
Accounts, etc. The entries made in the accounts maintained pursuant to section 2.6(d) and (e) shall be prima facie evidence of the existence and amounts and amounts of the obligations recorded therein; provided, that
the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay or prepay the Loans in accordance with the terms of this Agreement.

  
 (g) Endorsements of Amounts on Notes Prior to
Transfer. Each Lender will, prior to any transfer of any of the Notes issued to it by the Borrower, endorse on the reverse side thereof or the grid attached thereto the outstanding principal amount of Loans evidenced thereby. Failure to make any
such notation or any error in any such notation shall not affect the Borrower’s obligations in respect of such Loans. 
  
 2.7. Voluntary Conversions of Dollar Denominated Loans; Redenomination of Loans. (a) The Borrower shall have the option to Convert on any
Business Day all or a portion at least equal to the applicable Minimum Borrowing Amount of the outstanding principal amount of its General Revolving Loans denominated in Dollars of one Type owing by it into a Borrowing or Borrowings pursuant to the
General Revolving Facility of another Type of Loans denominated in Dollars that can be made pursuant to such Facility, provided that: 
  
 (i) no Conversion may be made with respect to any Swing Line Revolving Loans; 
  
 (ii) no partial Conversion of a Borrowing of Eurodollar
Loans shall reduce the outstanding principal amount of the Eurodollar Loans made pursuant to such Borrowing to less than the Minimum Borrowing Amount applicable thereto; 
  
 (iii) any Conversion of Eurodollar Loans into Prime Rate Loans shall be made on, and only on, the last day
of an Interest Period for such Eurodollar Loans; 
  
 (iv) Prime Rate Loans may only be Converted into Eurodollar Loans if no Default under section 11.1(a) or Event of Default is in existence on the date of the Conversion unless the Required Lenders otherwise agree; 
  
 (v) Prime Rate Loans may not be Converted into Eurodollar
Loans during any period when such Conversion is not permitted under section 2.10; and 
  
 (vi) Borrowings of Eurodollar Loans resulting from this section 2.7 shall conform to the requirements of section 2.2(a). 
  
 Each such Conversion shall be effected by the Borrower giving the Administrative Agent at its
Notice Office, prior to 12:00 noon (local time at such Notice Office), at least three Business Days’, in the case of Conversion into a Eurodollar Loans (or prior to 12:00 noon (local time at such Notice Office) same Business Day’s, in the
case of a Conversion into Prime Rate Loans), prior written notice (or telephonic notice promptly confirmed in writing if so requested by the Administrative Agent) (each a “Notice of Conversion”), substantially in the form of
Exhibit B-2, specifying the Loans to be so Converted, the Type 

  

 - 29 - 








 
of Loans to be Converted into and, if to be Converted into a Borrowing of Eurodollar Loans, the Interest Period to be initially applicable thereto. The
Administrative Agent shall give each Lender prompt notice of any such proposed Conversion affecting any of its Loans. For the avoidance of doubt, the prepayment or repayment of any General Revolving Loans out of the proceeds of other General
Revolving Loans by the Borrower is not considered a Conversion of General Revolving Loans into other General Revolving Loans. 
  
 (b) The Borrower may, upon notice given to the Administrative Agent at least five Business Days prior to the date of the proposed
Redenomination, request that all Loans comprising the same Borrowing, or a portion of such Loans at least equal to the applicable Minimum Borrowing Amount, by the Borrower be Redenominated from Dollars into an Alternative Currency or from an
Alternative Currency into Dollars or another Alternative Currency; provided, however, that after giving effect to such Redenomination, there shall be no more than an aggregate of 8 Borrowings under the
General Revolving Facility and the Swingline Facility; and provided, further, that any Redenomination of Eurodollar Loans shall be made on, and only on, the last day of an Interest Period for such Loans; and
provided, still further, that no Redenomination shall be made that would cause any Prime Rate Loans to be denominated in any currency other than Dollars. Each such notice of request of a Redenomination (a
“Notice of Redenomination”) shall be by telecopier, telex or cable (confirmed immediately in writing if so requested by the Administrative Agent), in substantially the form of Exhibit B-3 hereto, specifying: (i) the Loans
comprising the Borrowing to be Redenominated; (ii) the date of the proposed Redenomination (which shall be a Business Day); (iii) the currency into which such Loans are to be Redenominated; and (iv) if such Loans as so Redenominated are to be
Eurodollar Loans, the duration of the Interest Period for such Loans upon being so Redenominated. The Administrative Agent shall promptly notify each affected Lender of any such requested Redenomination. In the case of a Notice of Redenomination
that requests a Redenomination of Loans into an Alternative Currency not described in clause (i) of the definition of the term Alternative Currency, such Redenomination is subject to the confirmation by each Lender to the Administrative Agent, not
later than the third Business Day before the requested date of such Redenomination that such Lender agrees to such Redenomination, and the Administrative Agent shall promptly notify the Borrower of such confirmation. If any affected Lender shall not
have so provided to the Administrative Agent such confirmation, the requested Redenomination will not occur, and the Administrative Agent shall promptly notify the Borrower and each affected Lender that a Lender has not provided such confirmation
and that the requested Redenomination will not occur. If each affected Lender shall have so provided to the Administrative Agent such confirmation or if such Notice of Redenomination requests a Redenomination of Loans into Dollars, each Loan so
requested to be Redenominated will be Redenominated, on the date specified therefor in such Notice of Redenomination, into an equivalent amount thereof in the currency requested in such Notice of Redenomination, such equivalent amount to be
determined on such date by the Administrative Agent in accordance with section 1.5, and in the case of any such Loan being so Redenominated that will be a Eurodollar Loan, such Eurodollar Loan will have an initial Interest Period as requested in
such Notice of Redenomination. 
  
 2.8. Interest. (a)
Interest Rate for Prime Rate Loans. During such periods as a General Revolving Loan or a Swing Line Revolving Loan is a Prime Rate Loan, the unpaid principal amount thereof shall bear interest at a fluctuating rate per annum that shall at all
times be equal to the Prime Rate in effect from time to time plus the Applicable Prime Rate Margin (as defined below) in effect from time to time. 
  

(b) Interest Rate for Eurodollar Loans. During such periods as a General Revolving Loan is a Eurodollar Loan, the unpaid principal amount
thereof shall bear interest at a rate per annum that shall at all times during any Interest Period applicable thereto be the Applicable Eurodollar Margin (as defined below) for such Eurodollar Loan plus the relevant Eurodollar Rate for
such Interest Period. 
  

 - 30 - 








 (c) Interest Rate for Eurodollar Market Index Rate Loans. During such periods as a Swing
Line Revolving Loan is a Eurodollar Market Index Rate Loan, the unpaid principal amount thereof shall bear interest at a fluctuating rate that shall at all times be equal to the Applicable Eurodollar Rate Margin (as defined below) plus
the Eurodollar Market Index Rate plus 50 basis points. 
  
 (d) Default Interest. Notwithstanding the above provisions, if an Event of Default is in existence, all outstanding amounts of principal and, to the extent permitted by law, all overdue interest, in
respect of each Loan shall bear interest, payable on demand, at a fluctuating rate per annum equal to 2% per annum above the interest rate that would be applicable under section 2.8(a) to Prime Rate Loans in effect from time to time. If any amount
(other than the principal of and interest on the Loans) payable by the Borrower under the Credit Documents is not paid when due, all amounts outstanding shall bear interest, payable on demand, at a fluctuating rate per annum equal 2% per annum above
the interest rate that would be applicable under section 2.8(a) to Prime Rate Loans in effect from time to time. 
  
 (e) Accrual and Payment of Interest. Interest shall accrue from and including the date of any Borrowing to but excluding the date of any
prepayment or repayment thereof and shall be payable: 
  
 (i) in the case of any Swing Line Revolving Loan, (A) at the maturity date thereof, (B) on the last Business Day of each month, (C) on any prepayment (on the amount prepaid), and (D) after maturity (whether by acceleration or otherwise), on
demand; and 
  
 (ii) in the case of any General
Revolving Loan, (A) that is a Prime Rate Loan, monthly in arrears on the last Business Day of each calendar month, (B) that is a Eurodollar Loan, on the last day of each Interest Period applicable thereto and, in the case of an Interest Period in
excess of three months, on the dates that are successively three months after the commencement of such Interest Period, and (C) on any repayment, prepayment or Conversion (on the amount repaid, prepaid or Converted), at maturity (whether by
acceleration or otherwise) and, after such maturity, on demand. 
  
 (f) Computations of Interest. All computations of interest hereunder shall be made in accordance with section 13.7(b). 
  
 (g) Information as to Interest Rates. The Administrative Agent upon determining the interest rate for any Borrowing shall promptly notify
the Borrower and the affected Lenders thereof. If the Administrative Agent is unable to determine the Eurodollar Rate for any Borrowing of Eurodollar Loans or the Eurodollar Market Index Rate for any Borrowing of Eurodollar Market Index Rate Loans
by reference to the Telerate screen or other information provided by a service organization referred to in clause (i) of the definition of the term Eurodollar Rate, then each Reference Bank agrees to furnish the Administrative Agent timely
information for the purpose of determining the Eurodollar Rate for any such Borrowing. If any one or more of the Reference Banks shall not timely furnish such information, the Administrative Agent shall determine the Eurodollar Rate on the basis of
timely information furnished by the remaining Reference Banks.

 (h) Interest Margins. As used herein, the term “Applicable Prime Rate
Margin,” as applied to any Loan that is a Prime Rate Loan, and the term “Applicable Eurodollar Margin,” as applied to any Loan that is a Eurodollar Loan, means the particular rate per annum determined by the
Administrative Agent in accordance with the Pricing Grid Table that appears below, based on the Borrower’s ratio of Consolidated Total Debt to Consolidated EBITDA and such Pricing Grid Table, and the following provisions: 
  
 (i) Initially, until changed hereunder in accordance with
the following provisions, the Applicable Prime Rate Margin will be zero basis points per annum and the Applicable Eurodollar Margin for General Revolving Loans will be 152.50 basis points per annum. 
  
 (ii) Upon receipt of the covenant compliance report for the
fiscal quarter of the Borrower ended on or nearest to March 31, 2004, and continuing with each fiscal quarter thereafter, the Administrative Agent will determine the Applicable Prime Rate Margin for any Prime Rate Loan and the Applicable Eurodollar
Margin for any Eurodollar Loan or Eurodollar Market Index Rate Loan in accordance with the Pricing Grid Table, based on the Borrower’s ratio of (x) Consolidated Total Debt as of the end of the fiscal quarter, to (y) Consolidated EBITDA for the
Testing Period ended on the last day of the fiscal quarter, and identified in such Pricing Grid Table. Changes in the Applicable Prime Rate Margin and the Applicable Eurodollar Margin based upon changes in such ratio shall become effective on the
first day of the month following the receipt by the Administrative Agent pursuant to section 9.1(a) or (b) of the financial statements of the Borrower, accompanied by the certificate and calculations referred to in section 9.1(c), demonstrating the
computation of such ratio, based upon the ratio in effect at the end of the applicable period covered (in whole or in part) by such financial statements. 
  
 (iii) Notwithstanding the above provisions, during any period when (A) the Borrower has failed to timely deliver its consolidated
financial statements referred to in section 9.1(a) or (b), accompanied by the certificate and calculations referred to in section 9.1(c), or (B) an Event of Default has occurred and is continuing, the Applicable Prime Rate Margin and the Applicable
Eurodollar Margin shall each be the highest rate per annum indicated therefor in the Pricing Grid Table, regardless of the Borrower’s ratio of Consolidated Total Debt to Consolidated EBITDA at such time. 
  
 (iv) Any changes in the Applicable Prime Rate Margin or the
Applicable Eurodollar Margin shall be determined by the Administrative Agent in accordance with the above provisions and the Administrative Agent will promptly provide notice of such determinations to the Borrower and the Lenders. Any such
determination by the Administrative Agent pursuant to this section 2.8(h) shall be conclusive and binding absent manifest error.

 2.9. Selection and
Continuation of Interest Periods. (a) The Borrower shall have the right 
  
 (x) at the time it gives a Notice of Borrowing or Notice of Conversion in respect of the making of, or a Conversion into, General Revolving Loans consisting of 

  

 - 32 - 








 
Eurodollar Loans, to select in such Notice the Interest Period to be applicable to such Borrowing; and 
  
 (y) prior to 11:00 A.M. (local time at the Notice Office) on
the third Business Day prior to the expiration of an Interest Period applicable to a Borrowing of General Revolving Loans consisting of Eurodollar Loans, to elect by giving the Administrative Agent written or telephonic notice (in the case of
telephonic notice, promptly confirmed in writing if so requested by the Administrative Agent) to Continue all or the Minimum Borrowing Amount of the principal amount of such Loans as one or more Borrowings of Eurodollar Loans and to select the
Interest Period to be applicable to any such Borrowing (any such notice, a “Notice of Continuation”), 
  
 which Interest Period shall, at the option of the Borrower, be a one, two, three or six month period; provided, that notwithstanding anything to the
contrary contained above, the Borrower’s right to select an Interest Period or to effect any Continuation shall be subject to the applicable provisions of section 2.10 and to the following: 
  
 (i) the initial Interest Period for any Borrowing of
Eurodollar Loans shall commence on the date of such Borrowing (the date of a Borrowing resulting from a Conversion or Continuation shall be the date of such Conversion or Continuation) and each Interest Period occurring thereafter in respect of such
Borrowing shall commence on the day on which the next preceding Interest Period expires; 
  
 (ii) if any Interest Period begins on a day for which there is no numerically corresponding day in the calendar month at the end of such
Interest Period, such Interest Period shall end on the last Business Day of such calendar month; 
  
 (iii) if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day, provided that if any Interest Period would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall
expire on the next preceding Business Day; 
  
 (iv) no Interest Period for any Eurodollar Loan may be selected that would end after the Maturity Date; 
  
 (v) each Borrowing of Eurodollar Loans resulting from any Continuation shall be in at least the Minimum Borrowing Amount applicable
thereto; and 
  
 (vi) no Interest Period may be
elected at any time when a Default under section 11.1(a) or an Event of Default is then in existence unless the Required Lenders otherwise agree. 
  
 (b) If upon the expiration of any Interest Period the Borrower has failed to (or may not) elect a new Interest Period to be applicable to
the respective Borrowing of Eurodollar Loans as provided above, in the case of any such Eurodollar Loans that are denominated in Dollars, the Borrower shall be deemed to have elected to Convert such Borrowing to Prime Rate Loans effective as of the
expiration date of such current Interest Period, and in the case of any such Eurodollar Loans that are denominated in an Alternative Currency, the Borrower shall be deemed to have elected effective as of the expiration date of such current Interest
Period to Redenominate such Loans from the applicable Alternative Currency into an equivalent amount thereof in Dollars, such equivalent amount to be determined on such date by the Administrative Agent in accordance with section 1.5, and to treat
such Loans as so Redenominated as Prime Rate Loans. 
  

 - 33 - 








 2.10. Increased Costs, Illegality, etc. (a) In the event that (x) in the case of clause (i)
below, the Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any Lender, shall have determined on a reasonable basis (which determination shall, absent manifest error, be final and conclusive and binding upon all parties
hereto): 
  
 (i) on any date for determining the
Eurodollar Rate for Eurodollar Loans denominated in Dollars or in an Alternative Currency for any Interest Period, or for Eurodollar Market Index Rate Loans, as applicable, that, by reason of any changes arising after the Effective Date affecting
the interbank Eurodollar market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Eurodollar Rate; or 
  
 (ii) at any time, that such Lender shall incur increased costs or reductions in the amounts received or
receivable hereunder in an amount that such Lender reasonably deems material with respect to any Eurodollar Loans (other than any increased cost or reduction in the amount received or receivable resulting from the imposition of or a change in the
rate of taxes or similar charges) because of (x) any change since the Effective Date in any applicable law, governmental rule, regulation, guideline, order or request (whether or not having the force of law), or in the interpretation or
administration thereof and including the introduction of any new law or governmental rule, regulation, guideline, order or request (such as, for example, but not limited to, a change in official reserve requirements, but, in all events, excluding
reserves includable in the Eurodollar Rate pursuant to the definition thereof) and/or (y) other circumstances adversely affecting the interbank Eurodollar market or the position of such Lender in such market; or 
  
 (iii) at any time, that the making or continuance of any
Eurodollar Loan denominated in Dollars or in an Alternative Currency has become unlawful by compliance by such Lender in good faith with any change since the Effective Date in any law, governmental rule, regulation, guideline or order, or the
interpretation or application thereof, or would conflict with any thereof not having the force of law but with which such Lender customarily complies or has become impracticable as a result of a contingency occurring after the Effective Date that
materially adversely affects the interbank Eurodollar market; 
  
 then, and in any such event, such Lender (or the Administrative Agent in the case of clause (i) above) shall (x) on or promptly following such date or time and (y) within 10 Business Days of the date on which such event no
longer exists give notice (by telephone confirmed in writing) to the Borrower and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other applicable Lenders). Thereafter
(x) in the case of clause (i) above, Eurodollar Loans, or for Eurodollar Market Index Rate Loans, as applicable, shall no longer be available in the applicable currency until such time as the Administrative Agent notifies the Borrower and the
applicable Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist, and any Notice of Borrowing, Notice of Conversion or Notice of Redenomination given by the Borrower with respect to Eurodollar Loans
denominated in Dollars or such Alternative Currency, or for Eurodollar Market Index Rate Loans, as applicable, that have not yet been incurred, Converted or Redenominated shall be deemed rescinded by the Borrower or, in the case of a Notice of
Borrowing, shall, at the option of the Borrower, be deemed Converted into a Notice of Borrowing for Prime Rate Loans to be made on the date of Borrowing contained in such Notice of Borrowing, (y) in the case of clause (ii) above, the Borrower shall
pay to such Lender, upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender shall determine) as shall be required to compensate such
Lender, for such increased costs or reductions in amounts receivable hereunder (a written notice as to the additional amounts owed to such Lender, showing the basis for the calculation thereof, which basis must be reasonable, submitted to the


  

 - 34 - 








 
Borrower by such Lender shall, absent manifest error, be final and conclusive and binding upon all parties hereto) and (z) in the case of clause (iii) above,
the Borrower shall take one of the actions specified in section 2.10(b) as promptly as possible and, in any event, within the time period required by law. 
  
 (b) At any time that any Eurodollar Loan denominated in Dollars or in an Alternative Currency is affected by the circumstances described in
section 2.10(a)(ii) or (iii), the Borrower may (and in the case of a Eurodollar Loan affected pursuant to section 2.10(a)(iii) the Borrower shall) either (i) if the affected Eurodollar Loan is then being made pursuant to a Borrowing, by giving the
Administrative Agent telephonic notice (confirmed promptly in writing) thereof on the same date that the Borrower was notified by a Lender pursuant to section 2.10(a)(ii) or (iii), cancel said Borrowing, convert the related Notice of Borrowing into
one requesting a Borrowing of Prime Rate Loans or require the affected Lender to make its requested Loan as a Prime Rate Loan, or (ii) if the affected Eurodollar Loan is then outstanding, upon at least one Business Day’s notice to the
Administrative Agent, require the affected Lender to Convert each such Eurodollar Loan denominated in Dollars into a Prime Rate Loan or require the affected Lender to Redenominate each such Eurodollar Loan denominated in an Alternative Currency into
a Prime Rate Loan, provided that if more than one Lender is affected at any time, then all affected Lenders must be treated the same pursuant to this section 2.10(b). 
  
 (c) If any Lender shall have determined that after the Effective Date, the adoption of any applicable law,
rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged by law with the interpretation or
administration thereof, or compliance by such Lender or its parent corporation with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank, or comparable agency, in each case
made subsequent to the Effective Date, has or would have the effect of reducing by an amount reasonably deemed by such Lender to be material the rate of return on such Lender’s or its parent corporation’s capital or assets as a consequence
of such Lender’s commitments or obligations hereunder to a level below that which such Lender or its parent corporation could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s
or its parent corporation’s policies with respect to capital adequacy), then from time to time, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount
or amounts as will compensate such Lender or its parent corporation for such reduction. Each Lender, upon determining in good faith that any additional amounts will be payable pursuant to this section 2.10(c), will give prompt written notice thereof
to the Borrower, which notice shall set forth, in reasonable detail, the basis of the calculation of such additional amounts, which basis must be reasonable, although the failure to give any such notice shall not release or diminish any of the
Borrower’s obligations to pay additional amounts pursuant to this section 2.10(c) upon the subsequent receipt of such notice. 
  
 (d) Notwithstanding anything in this Agreement to the contrary, (i) no Lender shall be entitled to compensation or payment or reimbursement
of other amounts under section 2.10 for any amounts incurred or accruing more than 270 days prior to the giving of notice to the Borrower of additional costs or other amounts of the nature described in such section, and (ii) no Lender shall demand
compensation for any reduction referred to in section 2.10(c) if it shall not at the time be the general policy or practice of such Lender to demand such compensation, payment or reimbursement in similar circumstances under comparable provisions of
other credit agreements. 
  
 2.11. Breakage
Compensation. The Borrower shall compensate each applicable Lender, upon its written request (which request shall set forth the detailed basis for requesting and the method of calculating such compensation), for all reasonable losses, expenses
and liabilities (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund its Eurodollar Loans) that such Lender may sustain: (i)
if for any reason (other than a default by such Lender or the Administrative Agent), a Borrowing of 

  

 - 35 - 








 
Eurodollar Loans does not occur on a date specified therefor in a Notice of Borrowing, Notice of Conversion or Notice of Redenomination (whether or not
rescinded or withdrawn by the Borrower or deemed rescinded or withdrawn pursuant to section 2.10(a)); (ii) if any repayment, prepayment, Conversion, Redenomination or Continuation of any of its Eurodollar Loans occurs on a date that is not the last
day of an Interest Period applicable thereto; (iii) if any prepayment of any of its Eurodollar Loans is not made on any date specified in a notice of prepayment given by the Borrower; (iv) if such Lender transfers its Eurodollar Loans pursuant to a
request by the Borrower under section 2.12(b) hereof; or (v) as a consequence of (x) any other default by the Borrower to repay its Eurodollar Loans when required by the terms of this Agreement or (y) an election made pursuant to section 2.10(b).
Such loss, cost, expense and liability to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest that would have accrued on the principal amount of such Loan had such event
not occurred, at the interest rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to effect a Borrowing, Conversion,
Redenomination or Continuation, for the period that would have been the Interest Period for such Loan, over (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate that such Lender would bid were
it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive
pursuant to this section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such request within 10 days after receipt thereof. 
  
 2.12. Change of Lending Office; Replacement of Lenders.
(a) Each Lender agrees that, upon the occurrence of any event giving rise to the operation of section 2.10(a)(ii) or (iii) or 2.10(c), with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to
overall policy considerations of such Lender) to designate another Applicable Lending Office for any Loans or Commitment affected by such event, provided that such designation is made on such terms that such Lender and its Applicable
Lending Office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such section. 
  
 (b) If any Lender requests any compensation, reimbursement or other payment under section 2.10(a)(ii) or (iii)
or 2.10(c) with respect to such Lender, or if any Lender is a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with the restrictions contained in section 13.4(c)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts
such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld, (ii) such Lender shall have received payment of an amount
equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts, including any breakage compensation under section 2.11 hereof), and (iii) in the case of any such assignment resulting from a claim for compensation, reimbursement or other payments required to be made under section
2.10(a)(ii) or (iii) or 2.10(c) with respect to such Lender, such assignment will result in a reduction in such compensation, reimbursement or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as
a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. 
  
 (c) Nothing in this section 2.12 shall affect or postpone any of the obligations of the Borrower or the right of any Lender provided in
section 2.10.

 SECTION 3. LETTERS OF CREDIT. 
  
 3.1. Letters of Credit. (a) Subject to and upon the terms and conditions herein set forth, the
Borrower may request a Letter of Credit Issuer at any time and from time to time on or after the Closing Date and prior to the date that is 15 Business Days prior to the Maturity Date to issue, for the account of the Borrower or any of its
Subsidiaries and in support of workers’ compensation, liability insurance, releases of contract retention obligations, contract performance guarantee requirements and other bonding and other obligations of the Borrower or any such Subsidiary
incurred in the ordinary course of its business, and such other standby obligations of the Borrower and its Subsidiaries that are acceptable to the Letter of Credit Issuer, and subject to and upon the terms and conditions herein set forth, such
Letter of Credit Issuer agrees to issue from time to time, irrevocable standby letters of credit denominated and payable in Dollars or in an Alternative Currency in such form as may be approved by such Letter of Credit Issuer and the Administrative
Agent (each such letter of credit (and each Existing Letter of Credit described in section 3.1(d)), a “Letter of Credit” and collectively, the “Letters of Credit”). 
  
 (b) Notwithstanding the foregoing: (i) no Letter of Credit
shall be issued the Stated Amount of which, when added to the Letter of Credit Outstandings at such time, would exceed either (x) $30,000,000 (“Letter of Credit Sublimit”), or (y) when added to the aggregate principal amount
of all Loans then outstanding, an amount equal to the Total Commitment at such time; (ii) no individual Letter of Credit (other than any Existing Letter of Credit) shall be issued that has an initial Stated Amount less than $10,000 unless such
lesser Stated Amount is acceptable to the Letter of Credit Issuer; and (iii) each Letter of Credit shall have an expiry date (including any renewal periods) occurring not later than the earlier of (A) one year from the date of issuance thereof,
unless a longer period is approved by the relevant Letter of Credit Issuer and Lenders (other than any Defaulting Lender) holding a majority of the Total Commitment, and (B) 15 Business Days prior to the Maturity Date, in each case on terms
acceptable to the Administrative Agent and the relevant Letter of Credit Issuer, provided, however, that in the case of this subclause (B), the expiry date (including any renewal periods) may be permitted to
occur beyond the Maturity Date so long as the Borrower shall pay to the applicable Letter of Credit Issuer an amount in cash and/or Cash Equivalents equal to 100% of the Letter of Credit Outstandings and such Letter of Credit Issuer shall hold such
payment as security for the reimbursement obligations of the Borrower in respect of the applicable Letter of Credit pursuant to a cash collateral agreement to be entered into in form and substance reasonably satisfactory to such Letter of Credit
Issuer and the Borrower (which shall permit certain investments in Cash Equivalents satisfactory to such Letter of Credit Issuer and the Borrower until the proceeds are applied to the secured obligations). 
  
 (c) Notwithstanding the foregoing, in the event a Lender
Default exists, no Letter of Credit Issuer shall be required to issue any Letter of Credit unless either: (i) such Letter of Credit Issuer has entered into arrangements satisfactory to it and the Borrower to eliminate such Letter of Credit
Issuer’s risk with respect to the participation in Letters of Credit of the Defaulting Lender or Lenders, including by cash collateralizing such Defaulting Lender’s or Lenders’ Percentage of the Letter of Credit Outstandings; or (ii)
the issuance of such Letter of Credit, taking into account the potential failure of the Defaulting Lender or Lenders to risk participate therein, will not cause the Letter of Credit Issuer to incur aggregate credit exposure hereunder with respect to
Loans and Letter of Credit Outstandings in excess of its Commitment, and the Borrower has undertaken, for the benefit of such Letter of Credit Issuer, pursuant to an instrument satisfactory in form and substance to such Letter of Credit Issuer, not
to thereafter incur Loans or Letter of Credit Outstandings hereunder that would cause the Letter of Credit Issuer to incur aggregate credit exposure hereunder with respect to Loans and Letter of Credit Outstandings in excess of its Commitment.

  
 (d) Annex VI hereto contains a description of
all letters of credit outstanding on, and to continue in effect after, the Closing Date. Each such letter of credit issued by a bank that is or becomes a Lender under this Agreement (each, an “Existing Letter of Credit”)
shall constitute a “Letter of Credit” 

  

 - 37 - 








 
for all purposes of this Agreement, issued, for purposes of section 3.4(a), on the Closing Date, and the Borrower, the Administrative Agent and the
applicable Lenders hereby agree that, from and after such date, the terms of this Agreement shall apply to such Letters of Credit, superseding any other agreement theretofore applicable to them to the extent inconsistent with the terms hereof.

  
 3.2. Letter of Credit Requests; Notices of
Issuance. (a) Whenever it desires that a Letter of Credit be issued, the Borrower shall give the Administrative Agent and the Letter of Credit Issuer written or telephonic notice (in the case of telephonic notice, promptly
confirmed in writing if so requested by the Administrative Agent) that, if in the form of written notice shall be substantially in the form of Exhibit B-4, or transmit by electronic communication (if arrangements for doing so have been approved by
the Letter of Credit Issuer), prior to 11:00 A.M. (local time at its Notice Office) at least three Business Days (or such shorter period as may be acceptable to the relevant Letter of Credit Issuer) prior to the proposed date of issuance (which
shall be a Business Day) (each a “Letter of Credit Request”), which Letter of Credit Request shall include such supporting documents that such Letter of Credit Issuer customarily requires in connection therewith (including,
in the case of a Letter of Credit for an account party other than the Borrower, an application for, and if applicable a reimbursement agreement with respect to, such Letter of Credit). Any such documents executed in connection with the issuance of a
Letter of Credit, including the Letter of Credit itself, are herein referred to as “Letter of Credit Documents.” In the event of any inconsistency between any of the terms or provisions of any Letter of Credit Document and
the terms and provisions of this Agreement respecting Letters of Credit, the terms and provisions of this Agreement shall control. The Administrative Agent shall promptly notify each Lender of each Letter of Credit Request. 
  
 (b) Each Letter of Credit Issuer shall provide to the
Administrative Agent and each other Lender (i) a monthly summary describing each Letter of Credit issued by such Letter of Credit Issuer and then outstanding and an identification for the relevant period of the daily aggregate Letter of Credit
Outstandings represented by Letters of Credit issued by such Letter of Credit Issuer and (ii) notice immediately upon any increase or decrease in the face amount of any Letter of Credit or any termination or cancellation of any Letter of Credit.
Each Letter of Credit Issuer shall, if requested by the Administrative Agent or any other Lender, provide a copy of each Letter of Credit issued by it. 
  
 3.3. Agreement to Repay Letter of Credit Drawings. (a) The Borrower hereby agrees to reimburse (or cause any Subsidiary for
whose account a Letter of Credit was issued to reimburse) each Letter of Credit Issuer, by making payment directly to such Letter of Credit Issuer in immediately available funds at the payment office of such Letter of Credit Issuer, for any payment
or disbursement made by such Letter of Credit Issuer under any Letter of Credit (each such amount so paid or disbursed until reimbursed, an “Unpaid Drawing”) not later than the Business Day immediately following the Business
Day on which such Letter of Credit Issuer notifies the Borrower (or any such Subsidiary for whose account such Letter of Credit was issued) of such payment or disbursement (which notice to the Borrower (or such Subsidiary) shall be delivered
reasonably promptly after any such payment or disbursement), such payment to be made in Dollars, with interest on the amount so paid or disbursed by such Letter of Credit Issuer, to the extent not reimbursed prior to 1:00 P.M. (local time at the
payment office of the Letter of Credit Issuer) on the date of such payment or disbursement, from and including the date paid or disbursed to but not including the date such Letter of Credit Issuer is reimbursed therefor at a rate per annum that
shall be the rate then applicable to Loans that are Prime Rate Loans (plus an additional 2% per annum if not reimbursed by the third Business Day after the date of such payment or disbursement), any such interest also to be payable on demand. If by
11:00 A.M. on the Business Day immediately following notice to it of its obligation to make reimbursement in respect of an Unpaid Drawing, the Borrower has not made such reimbursement out of its available cash on hand or a contemporaneous Borrowing
hereunder, (x) the Borrower will be deemed to have given a Notice of Borrowing for Prime Rate Loans in an aggregate principal amount sufficient to reimburse such Unpaid 

  

 - 38 - 








 
Drawing (and the Administrative Agent shall promptly give notice to the Lenders of such deemed Notice of Borrowing), (y) the Lenders shall, unless they are
legally prohibited from doing so, make the Loans contemplated by such deemed Notice of Borrowing (which Loans shall be considered made under section 2.1 hereof), and (z) the proceeds of such Prime Rate Loans shall be disbursed directly to the
applicable Letter of Credit Issuer to the extent necessary to effect such reimbursement, with any excess proceeds to be made available to the Borrower in accordance with the applicable provisions of this Agreement. 
  
 (b) The Borrower’s obligation under this section 3.3 to
reimburse, or cause a Subsidiary to reimburse, each Letter of Credit Issuer with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any
setoff, counterclaim or defense to payment that the Borrower may have or have had against such Letter of Credit Issuer, the Administrative Agent, any other Letter of Credit Issuer or any Lender, including, without limitation, any defense based upon
the failure of any drawing under a Letter of Credit to conform to the terms of the Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such drawing, provided, however that the Borrower shall
not be obligated to reimburse, or cause a Subsidiary to reimburse, a Letter of Credit Issuer for any wrongful payment made by such Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or
gross negligence on the part of such Letter of Credit Issuer. 
  
 3.4. Letter of Credit Participations. (a) Immediately upon the issuance by a Letter of Credit Issuer of any Letter of Credit (and on the Closing Date with respect to any Existing Letter of Credit), such Letter of Credit
Issuer shall be deemed to have sold and transferred to each Lender with a Commitment, and each such Lender (each a “Participant”) shall be deemed irrevocably and unconditionally to have purchased and received from such Letter
of Credit Issuer, without recourse or warranty, an undivided interest and participation, to the extent of such Lender’s Percentage, in such Letter of Credit, each substitute letter of credit, each drawing made thereunder, the obligations of the
Borrower under this Agreement with respect thereto (although Letter of Credit Fees shall be payable directly to the Administrative Agent for the account of the Lenders as provided in section 4.2 and the Participants shall have no right to receive
any portion of any fees of the nature contemplated by section 4.3), the obligations of any Subsidiary of the Borrower under any Letter of Credit Documents pertaining thereto, and any security for, or guaranty pertaining to, any of the foregoing.
Upon any change in the Commitments of the Lenders pursuant to section 13.4(b), it is hereby agreed that, with respect to all outstanding Letters of Credit and Unpaid Drawings, there shall be an automatic adjustment to the participations pursuant to
this section 3.4 to reflect the new Percentages of the assigning and assignee Lender. 
  
 (b) In determining whether to pay under any Letter of Credit, a Letter of Credit Issuer shall not have any obligation relative to the Participants other than to determine that any documents required to
be delivered under such Letter of Credit have been delivered and that they appear to comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by a Letter of Credit Issuer under or in connection
with any Letter of Credit if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for such Letter of Credit Issuer any resulting liability. 
  
 (c) In the event that a Letter of Credit Issuer makes any payment under any Letter of Credit and the Borrower
shall not have reimbursed (or caused any applicable Subsidiary to reimburse) such amount in full to such Letter of Credit Issuer pursuant to section 3.3(a), such Letter of Credit Issuer shall promptly notify the Administrative Agent, and the
Administrative Agent shall promptly notify each Participant of such failure, and each Participant shall promptly and unconditionally pay to the Administrative Agent for the account of such Letter of Credit Issuer, the amount of such
Participant’s Percentage of such payment in U.S. dollars and in same day funds, provided, however, that no Participant shall be obligated to pay to the Administrative Agent its Percentage of such unreimbursed amount for any
wrongful payment made by such Letter of Credit Issuer under a Letter of Credit as a result of acts or 

  

 - 39 - 








 
omissions constituting willful misconduct or gross negligence on the part of such Letter of Credit Issuer. If the Administrative Agent so notifies any
Participant required to fund a payment under a Letter of Credit prior to 11:00 A.M. (local time at its Notice Office) on any Business Day, such Participant shall make available to the Administrative Agent for the account of the relevant Letter of
Credit Issuer such Participant’s Percentage of the amount of such payment on such Business Day in same day funds. If and to the extent such Participant shall not have so made its Percentage of the amount of such payment available to the
Administrative Agent for the account of the relevant Letter of Credit Issuer, such Participant agrees to pay to the Administrative Agent for the account of such Letter of Credit Issuer, forthwith on demand such amount, together with interest
thereon, for each day from such date until the date such amount is paid to the Administrative Agent for the account of such Letter of Credit Issuer at the Federal Funds Effective Rate. The failure of any Participant to make available to the
Administrative Agent for the account of the relevant Letter of Credit Issuer its Percentage of any payment under any Letter of Credit shall not relieve any other Participant of its obligation hereunder to make available to the Administrative Agent
for the account of such Letter of Credit Issuer its Percentage of any payment under any Letter of Credit on the date required, as specified above, but no Participant shall be responsible for the failure of any other Participant to make available to
the Administrative Agent for the account of such Letter of Credit Issuer such other Participant’s Percentage of any such payment. 
  
 (d) Whenever a Letter of Credit Issuer receives a payment of a reimbursement obligation as to which the Administrative Agent has received
for the account of such Letter of Credit Issuer any payments from the Participants pursuant to section 3.4(c) above, such Letter of Credit Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each
Participant that has paid its Percentage thereof, in U.S. dollars and in same day funds, an amount equal to such Participant’s Percentage of the principal amount thereof and interest thereon accruing after the purchase of the respective
participations, as and to the extent so received. 
  
 (e) The obligations of the Participants to make payments to the Administrative Agent for the account of each Letter of Credit Issuer with respect to Letters of Credit shall be irrevocable and not subject to counterclaim,
set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including, without limitation, any of the following circumstances:

  
 (i) any lack of validity or enforceability of
this Agreement or any of the other Credit Documents; 
  
 (ii) the existence of any claim, set-off defense or other right that the Borrower (or any Subsidiary) may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any person for whom any
such transferee may be acting), the Administrative Agent, any Letter of Credit Issuer, any Lender, or other person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions
(including any underlying transaction between the Borrower (or any Subsidiary) and the beneficiary named in any such Letter of Credit), other than any claim that the Borrower (or any Subsidiary that is the account party with respect to a Letter of
Credit) may have against any applicable Letter of Credit Issuer for gross negligence or willful misconduct of such Letter of Credit Issuer in making payment under any applicable Letter of Credit; 
  
 (iii) any draft, certificate or other document presented
under the 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; 
  
 (iv) the surrender or impairment of any security for the performance or observance of any of the terms of
any of the Credit Documents: or 
  

 - 40 - 








 (v) the occurrence of any Default or Event of Default. 
  
 (f) To the extent the Letter of Credit Issuer is not
indemnified by the Borrower, the Participants will reimburse and indemnify the Letter of Credit Issuer, in proportion to their respective Percentages, for and against any and all liabilities, obligations, losses, damages, penalties, claims, actions,
judgments, costs, expenses or disbursements of whatsoever kind or nature that may be imposed on, asserted against or incurred by the Letter of Credit Issuer in performing its respective duties in any way related to or arising out of its issuance of
Letters of Credit, provided that no Participants shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements resulting from the Letter of
Credit Issuer’s gross negligence or willful misconduct. 
  
 3.5. Increased Costs. If after the Effective Date, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Letter of Credit Issuer or any Lender with any request or directive (whether or not having the force of law) by any such
authority, central bank or comparable agency (in each case made subsequent to the Effective Date) shall either: (i) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against Letters of Credit issued by
such Letter of Credit Issuer or such Lender’s participation therein; or (ii) shall impose on such Letter of Credit Issuer or any Lender any other conditions affecting this Agreement, any Letter of Credit or such Lender’s participation
therein; and the result of any of the foregoing is to increase the cost to such Letter of Credit Issuer or such Lender of issuing, maintaining or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by
such Letter of Credit Issuer or such Lender hereunder (other than any increased cost or reduction in the amount received or receivable resulting from the imposition of or a change in the rate of taxes or similar charges), then, upon demand to the
Borrower by such Letter of Credit Issuer or such Lender (a copy of which notice shall be sent by such Letter of Credit Issuer or such Lender to the Administrative Agent), the Borrower shall pay to such Letter of Credit Issuer or such Lender such
additional amount or amounts as will compensate any such Letter of Credit Issuer or such Lender for such increased cost or reduction. A certificate submitted to the Borrower by any Letter of Credit Issuer or any Lender, as the case may be (a copy of
which certificate shall be sent by such Letter of Credit Issuer or such Lender to the Administrative Agent), setting forth, in reasonable detail, the basis for the determination of such additional amount or amounts necessary to compensate any Letter
of Credit Issuer or such Lender as aforesaid shall be conclusive and binding on the Borrower absent manifest error, although the failure to deliver any such certificate shall not release or diminish any of the Borrower’s obligations to pay
additional amounts pursuant to this section 3.5. Reference is hereby made to the provisions of sections 2.10(d) and 2.12 for certain limitations upon the rights of a Letter of Credit Issuer or Lender under this section. 
  
 3.6. Guaranty of Subsidiary Letter of Credit
Obligations. (a) The Borrower hereby unconditionally guarantees, for the benefit of the Administrative Agent and the Lenders, the full and punctual payment of the Obligations of each Subsidiary under each Letter of Credit Document
to which such Subsidiary is now or hereafter becomes a party. Upon failure by any such Subsidiary to pay punctually any such amount, the Borrower shall forthwith on demand by the Administrative Agent pay the amount not so paid at the place and in
the currency and otherwise in the manner specified in this Agreement or any applicable Letter of Credit Document. 
  
 (b) As a separate, additional and continuing obligation, the Borrower unconditionally and irrevocably undertakes and agrees, for the benefit
of the Administrative Agent and the Lenders, that, should any amounts not be recoverable from the Borrower under section 3.6(a) for any reason whatsoever (including, without limitation, by reason of any provision of any Credit Document or any other
agreement or instrument executed in connection therewith being or becoming void, unenforceable, or otherwise 

  

 - 41 - 








 
invalid under any applicable law) then, notwithstanding any notice or knowledge thereof by any Lender, the Administrative Agent, any of their respective
Affiliates, or any other person, at any time, the Borrower as sole, original and independent obligor, upon demand by the Administrative Agent, will make payment to the Administrative Agent, for the account of the Lenders and the Administrative
Agent, of all such obligations not so recoverable by way of full indemnity, in such currency and otherwise in such manner as is provided in the Credit Documents. 
  
 (c) The obligations of the Borrower under this section shall be unconditional and absolute and, without
limiting the generality of the foregoing shall not be released, discharged or otherwise affected by the occurrence, one or more times, of any of the following: 
  

(i) any extension, renewal, settlement, compromise, waiver or release in respect to any obligation of any Subsidiary under any Letter
of Credit Document, by operation of law or otherwise; 
  
 (ii) any modification or amendment of or supplement to this Agreement, any Note or any other Credit Document; 
  
 (iii) any release, non-perfection or invalidity of any direct or indirect security for any obligation of the Borrower under this
Agreement, any Note or any other Credit Document or of any Subsidiary under any Letter of Credit Document; 
  
 (iv) any change in the corporate existence, structure or ownership of any Subsidiary or any insolvency, bankruptcy, reorganization or
other similar proceeding affecting any Subsidiary or its assets or any resulting release or discharge of any obligation of any Subsidiary contained in any Letter of Credit Document; 
  
 (v) the existence of any claim, set-off or other rights that the Borrower may have at any time against any
Subsidiary, the Administrative Agent, any Lender or any other person, whether in connection herewith or any unrelated transactions; 
  
 (vi) any invalidity or unenforceability relating to or against any Subsidiary for any reason of any Letter of Credit Document, or any
provision of applicable law or regulation purporting to prohibit the payment by any Subsidiary of any Obligations in respect of any Letter of Credit; or 
  
 (vii) any other act or omission to act or delay of any kind by any Subsidiary, the Administrative Agent, any Lender or any other person or
any other circumstance whatsoever that might, but for the provisions of this section, constitute a legal or equitable discharge of the Borrower’s obligations under this section. 
  
 (d) The Borrower’s obligations under this section shall remain in full force and effect until the
Commitments shall have terminated and the principal of and interest on the Notes and all other amounts payable by the Borrower under the Credit Documents and by any Subsidiary under the Letter of Credit Documents shall have been paid in full. If at
any time any payment of any of the Obligations of any Subsidiary in respect of any Letter of Credit Document is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of such Subsidiary, the
Borrower’s obligations under this section with respect to such payment shall be reinstated at such time as though such payment had been due but not made at such time. 
  
 (e) The Borrower irrevocably waives acceptance hereof, presentment, demand, protest and any notice not
provided for herein, as well as any requirement that at any time any action be taken by any 

  

 - 42 - 








 
person against any Subsidiary or any other person, or against any collateral or guaranty of any other person. 
  
 (f) The Borrower hereby subordinates all rights, whether
arising by operation of law or otherwise, that it may have upon making any payment under this section to be subrogated to the rights of the payee against any Subsidiary with respect to such payment or otherwise to be reimbursed, indemnified or
exonerated by any Subsidiary in respect thereof, to the indefeasible payment in full of all of the Obligations. 
  
 (g) In the event that acceleration of the time for payment of any amount payable by any Subsidiary under any Letter of Credit Document is
stayed upon insolvency, bankruptcy or reorganization of such Subsidiary, all such amounts otherwise subject to acceleration under the terms of any applicable Letter of Credit Document shall nonetheless be payable by the Borrower under this section
forthwith on demand by the Administrative Agent. 
  
 SECTION 4.
FEES. 
  
 4.1. Facility Fee. (a) The Borrower
agrees to pay to the Administrative Agent a Facility Fee (“Facility Fee”), for the account of each Non-Defaulting Lender that has a General Revolving Commitment, for the period from and including the Effective Date to but not
including the date the Total General Revolving Commitment has been terminated and no General Revolving Loans are outstanding, which Facility Fee, in the case of any such Non-Defaulting Lender, shall be computed on the amount of the Total General
Revolving Commitment of such Non-Defaulting Lender, whether used or unused, at the Applicable Facility Fee Rate. The Facility Fee shall be due and payable in arrears on a nonrefundable basis, on the last Business Day of each March, June, September
and December and on the Maturity Date, for the preceding quarter (or shorter period, if applicable), based on a year of 360 days and the actual number of days elapsed in such period. 
  
 (b) As used herein, the term “Applicable Facility Fee Rate” means the particular rate
per annum determined by the Administrative Agent in accordance with the Pricing Grid Table that appears in section 2.8(h) hereof, based on the Borrower’s ratio of Consolidated Total Debt to Consolidated EBITDA, and the following provisions:

  
 (i) Initially, until changed hereunder in
accordance with the following provisions, the Applicable Facility Fee Rate will be 35 basis points per annum. 
  
 (ii) Commencing with the fiscal quarter of the Borrower ended on or nearest to March 31, 2004, and continuing for each fiscal quarter
thereafter, the Administrative Agent will determine the Applicable Facility Fee Rate in accordance with the Pricing Grid Table, based on the Borrower’s ratio of (x) Consolidated Total Debt as of the end of the fiscal quarter, to (y)
Consolidated EBITDA for the Testing Period ended on the last day of the fiscal quarter, and identified in such Pricing Grid Table. Changes in the Applicable Facility Fee Rate shall be made and effective as of the same date as is provided in section
2.8(h) in the case of the determination or re-determination of the Applicable Prime Rate Margin or Applicable Eurodollar Margin. 
  
 (iii) Notwithstanding the above provisions, during any period when (A) the Borrower has failed to timely deliver its consolidated
financial statements referred to in section 9.1(a) or (b), accompanied by the certificate and calculations referred to in section 9.1(c), or (B) an Event of Default has occurred and is continuing, the Applicable Facility Fee Rate shall be the
highest rate per annum indicated therefor in the Pricing Grid Table, regardless of the Borrower’s ratio of Consolidated Total Debt to Consolidated EBITDA at such time. 
  

 - 43 - 








 (iv) Any changes in the Applicable Facility Fee Rate shall be determined by the
Administrative Agent in accordance with the above provisions and the Administrative Agent will promptly provide notice of such determinations to the Borrower and the Lenders. Any such determination by the Administrative Agent pursuant to this
section 4.1(b) shall be conclusive and binding absent manifest error. 
  
 4.2. Letter of Credit Fees. The Borrower agrees to pay to the Administrative Agent, for the account of each Non-Defaulting Lender, pro rata on the basis of its Percentage, a fee in respect of each Letter of
Credit (the “Letter of Credit Fee”), payable quarterly in arrears on the last Business Day of each March, June, September and December and on the Maturity Date, computed at the rate per annum equal to the Applicable
Eurodollar Margin then in effect on the Stated Amount thereof for the period from the date of issuance (or any increase in the amount, or renewal or extension) to the expiration date thereof (including any extensions of such expiration date that may
be made at the election of the beneficiary thereof). Notwithstanding the above provisions, if an Event of Default is in existence, the Borrower will pay to the Administrative Agent, on demand, for the account of each Non-Defaulting Lender, pro
rata on the basis of its Percentage, an additional Letter of Credit Fee, computed at 2% per annum on the Stated Amount of each Letter of Credit for the period such Default or Event of Default is in existence. 
  
 4.3. Facing Fees. The Borrower agrees to pay directly to each
Letter of Credit Issuer, for its own account, a fee in respect of each Letter of Credit issued by it (a “Facing Fee”), payable quarterly in arrears on the last Business Day of each March, June, September and December and on
the Maturity Date, computed at a rate of 1/8 of 1% per annum on the Stated Amount thereof for the period from the date of issuance (or increase, renewal or extension) to the expiration date thereof (including any extensions of such expiration date
that may be made at the election of the beneficiary thereof. 
  
 4.4. Letter of Credit Administrative Fees. The Borrower agrees to pay directly to each Letter of Credit Issuer upon each issuance of, drawing under, and/or amendment, extension, renewal or transfer of, a Letter of Credit
issued by it such amount as shall at the time of such issuance, drawing, amendment, extension, renewal or transfer be the administrative or processing charge that such Letter of Credit Issuer customarily charges for issuances, drawings under or
amendments, extensions, renewals or transfers of, letters of credit issued by it. 
  
 4.5. Other Fees. The Borrower shall pay to the Administrative Agent on the Effective Date and thereafter for its own account and/or for distribution to the Lenders such fees as heretofore agreed by the
Borrower and the Administrative Agent in the Commitment Letter dated February 19, 2003. 
  
 4.6. Computations of Fees. All computations of Fees under this Agreement shall be made in accordance with section 13.7(b). 
  
 SECTION 5. REDUCTIONS AND TERMINATION OF COMMITMENTS. 
  
 5.1. Voluntary Termination/Reduction of Commitments. Upon at least three Business Days’ prior written
notice (or telephonic notice confirmed in writing) to the Administrative Agent at its Notice Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders), the Borrower shall have the right, without premium or
penalty, to: 
  
 (a) terminate the Total Commitment,
provided that all outstanding Loans are contemporaneously prepaid in accordance with section 6.1; 
  
 (b) terminate the Swing Line Revolving Commitment, provided that all outstanding Swing Line Revolving Loans are
contemporaneously prepaid in accordance with section 6.1; 
  

 - 44 - 








 (c) partially and permanently reduce the Unutilized Total General Revolving Commitment,
provided that: (i) any such reduction shall apply to proportionately and permanently reduce the General Revolving Commitment of each of the Lenders; (ii) any partial reduction of the Unutilized Total General Revolving Commitment
pursuant to this section 5.1(c) shall be in the amount of at least $5,000,000 (or, if greater, in integral multiples of $1,000,000); and (iii) after giving effect to any such partial reduction of the Unutilized Total General Revolving Commitment,
the Total General Revolving Commitment then in effect shall exceed the Swing Line Revolving Commitment then in effect by at least $20,000,000; and/or 
  
 (d) partially and permanently reduce the Unutilized Swing Line Revolving Commitment, provided that any partial reduction of
the Unutilized Swing Line Revolving Commitment pursuant to this section 5.1(d) shall be in the amount of at least $1,000,000 (or, if greater, in integral multiples of $1,000,000). 
  
 5.2. Mandatory Termination/Adjustments of Commitments, etc. (a) The Total Commitment (and the
Commitment of each Lender) shall terminate on February 27, 2004 unless the Closing Date has occurred on or prior to such date. 
  
 (b) The Total Commitment shall terminate (and the Commitment of each Lender shall terminate) on the earlier of (x) the Maturity Date and (y)
the date on which a Change of Control occurs. 
  
 (c)
The Total General Revolving Commitment shall be permanently reduced, without premium or penalty, at the time that any mandatory prepayment of General Revolving Loans would be made pursuant to section 6.2(e), (f), (g) or (h) if General Revolving
Loans were then outstanding in the full amount of the Total General Revolving Commitment then in effect, in an amount equal to the required prepayment of principal of General Revolving Loans that would be required to be made in such circumstance.
Any such reduction shall apply to proportionately and permanently reduce the General Revolving Commitment of each of the Lenders. The Borrower will provide at least three Business Days’ prior written notice (or telephonic notice confirmed in
writing) to the Administrative Agent at its Notice Office (which notice the Administrative Agent shall promptly transmit to each of the Lenders), of any reduction of the Total General Revolving Commitment pursuant to this section 5.2(c), specifying
the date and amount of the reduction. 
  
 SECTION 6. PAYMENTS.

  
 6.1. Voluntary Prepayments. The Borrower
shall have the right to prepay any of its Loans, in whole or in part, without premium or penalty, from time to time on the following terms and conditions: 
  
 (a) the Borrower shall give the Administrative Agent at the Notice Office written or telephonic notice (in the case of telephonic notice,
promptly confirmed in writing if so requested by the Administrative Agent) of its intent to prepay the Loans, the amount of such prepayment and (in the case of Eurodollar Loans) the specific Borrowing(s) pursuant to which made, which notice shall be
received by the Administrative Agent by:

 - 45 - 








 (b) in the case of prepayment of any Borrowings under the General Revolving Facility, each
partial prepayment of any such Borrowing shall be in an aggregate principal of at least $1,000,000 or an integral multiple of $500,000 in excess thereof, in the case of Prime Rate Loans, and at least $2,000,000 (or the substantial equivalent thereof
in any Alternative Currency) or an integral multiple of $1,000,000 (or the substantial equivalent thereof in any Alternative Currency) in excess thereof, in the case of Eurodollar Loans;

Prepaid. With respect to each repayment or prepayment of Loans required by this section 6.2, the Borrower shall designate the Types of Loans that are to be prepaid and the specific Borrowing(s) pursuant to which such repayment or prepayment is
to be made, provided that: (i) the Borrower shall first so designate all Loans that are Prime Rate Loans and Eurodollar Loans with Interest Periods ending on the date of repayment or prepayment prior to designating any other Eurodollar
Loans for repayment or prepayment; (ii) if the outstanding principal amount of Eurodollar Loans made pursuant to a Borrowing is reduced below the applicable Minimum Borrowing Amount as a result of any such repayment or prepayment, then all the Loans
outstanding pursuant to such Borrowing shall be Converted into Prime Rate Loans; and (iii) each repayment and prepayment of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans. In the absence of a
designation by the Borrower as described in the preceding sentence, the Administrative Agent shall, subject to the above, make such designation in its sole discretion with a view, but no obligation, to minimize breakage costs owing under section
2.11. Any repayment or prepayment of Eurodollar Loans pursuant to this section 6.2 shall in all events be accompanied by such compensation as is required by section 2.11.

be made in immediately available funds and in lawful money of the United States of America (in the case of Loans denominated in Dollars), or in the applicable Alternative Currency (in the case of Loans denominated in an Alternative Currency), at the
Payment Office, it being understood that written notice by the Borrower to the Administrative Agent to make a payment from the funds in the Borrower’s account at the Payment Office shall constitute the making of such payment to the extent of
such funds held in such account. Any payments under this Agreement that are made later than 11:00 A.M. (local time at the Payment Office) shall be deemed to have been made on the next succeeding Business Day. Whenever any payment to be made

applicable rate in effect immediately prior to such extension. 
  
 (b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and Fees then due hereunder and an Event of Default is not then in existence, such
funds shall be applied: (i) first, towards payment of interest and Fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and Fees then due to such parties; and (ii)
second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

be made without setoff, counterclaim or other defense. Except as provided for in section 6.4(b), all such payments will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees,
assessments or other charges of whatever nature now or hereafter imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein with respect to such payments (but excluding, except as provided in the second
succeeding sentence, any tax, imposed on or measured by the net income or net profits of a Lender pursuant to the laws of the jurisdiction under which such Lender is organized or the jurisdiction in which the principal office or Applicable Lending
Office of such Lender is located or any subdivision thereof or therein) and all interest, penalties or similar liabilities with respect to such nonexcluded taxes, levies imposts, duties, fees, assessments or other charges (all such nonexcluded taxes
levies, imposts, duties, fees assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, the Borrower agrees to pay the full amount of such Taxes and such additional
amounts as may be necessary so that every payment by them of all amounts due hereunder or under any Note, after withholding or deduction for or on account of any Taxes will not be less than the amount provided for herein or in such Note. If any
amounts are payable in respect of Taxes pursuant to the preceding sentence, the Borrower agrees to reimburse each Lender, upon the written request of such Lender for taxes imposed on or measured by the net income or profits of such Lender pursuant
to the laws of the jurisdiction in which such Lender is organized or in which the principal office or Applicable Lending Office of such Lender is located or under the laws of any political subdivision or taxing authority of any such jurisdiction in
which the principal office or Applicable Lending Office of such Lender is located and for any withholding of income or similar taxes imposed by the United States of America as such Lender shall determine are payable by, or withheld from, such Lender
in respect of such amounts so paid to or on behalf of such Lender pursuant to the preceding sentence and in respect of any amounts paid to or on behalf of such Lender pursuant to this sentence, which request shall be accompanied by a statement from
such Lender setting forth, in reasonable detail, the computations used in determining such amounts. The Borrower will furnish to the Administrative Agent within 45 days after the date the payment of any Taxes, or any withholding or deduction on
account thereof, is due pursuant to applicable law certified copies of tax receipts, or other evidence satisfactory to the relevant Lender, evidencing such payment by the Borrower. The Borrower will indemnify and hold harmless the Administrative
Agent and each Lender, and reimburse the Administrative Agent or such Lender upon its written request, for the amount of any Taxes so levied or imposed and paid or withheld by such Lender. 
  
 (b) Each Lender that is a Foreign Lender agrees to provide to
the Company and the Administrative Agent on or prior to the Effective Date, or in the cases of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to section 13.4 (unless the respective Lender was already a Lender
hereunder immediately prior to such assignment or transfer and such Lender is in compliance with the provisions of this section 6.4(b)), on the date of such assignment or transfer to such Lender, (i) two accurate and complete original signed copies
of Internal Revenue Service Form W-8BEN or W-8ECI (or successor forms) certifying to such Lender’s entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement or any Note, or

Exhibit D (any such certificate, a “Section 6.4(b)(ii) Certificate”) and (y) two accurate and complete original signed copies of Internal Revenue Service Form W 8 (or successor form) certifying to such Lender’s
entitlement to a complete exemption from United States withholding tax with respect to payments of interest to be made under this Agreement or any Note. In addition, each Lender agrees that from time to time after the Effective Date, when a lapse in
time or change in circumstances renders the previous certification obsolete or inaccurate in any material respect, it will deliver to the Borrower and the Administrative Agent two new accurate and complete original signed copies of Internal Revenue
Service Form W-8BEN or W-8ECI, and a section 6.4(b)(ii) 

  

 - 49 - 








 
Certificate, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued
exemption from or reduction in United States withholding tax with respect to payments under this Agreement or any Note, or it shall immediately notify the Borrower and the Administrative Agent of its inability to deliver any such Form or
Certificate, in which case such Lender shall not be required to deliver any such Form or Certificate pursuant to this section 6.4(b). Notwithstanding anything to the contrary contained in section 6.4(a), but subject to section 13.4(g) and the
immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold income or other similar taxes imposed by the United States (or any political subdivision or taxing authority
thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Lender that is a Foreign Lender and that has not provided to the Borrower such forms that establish a complete exemption from such deduction or
withholding and (y) the Borrower shall not be obligated pursuant to section 6.4(a) hereof to gross-up payments to be made to a Lender in respect of income or similar taxes imposed by the United States or any additional amounts with respect thereto
(I) if such Lender has not provided to the Borrower the Internal Revenue Service forms required to be provided to the Borrower pursuant to this section 6.4(b) or (II) in the case of a payment other than interest, to a Lender described in clause (ii)
above, to the extent that such forms do not establish a complete exemption from withholding of such taxes. Notwithstanding anything to the contrary contained in the preceding sentence or elsewhere in this section 6.4 and except as specifically
provided for in section 13.4(g), the Borrower agrees to pay additional amounts and indemnify each Lender in the manner set forth in section 6.4(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect
of any Taxes deducted or withheld by it as described in the previous sentence as a result of any changes after the Effective Date in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof,
relating to the deducting or withholding of income or similar Taxes. 
  
 (c) If any Lender, in its sole opinion, determines that it has finally and irrevocably received or been granted a refund in respect of any Taxes paid as to which indemnification has been paid by the Borrower pursuant to this
section, it shall promptly remit such refund (including any interest received in respect thereof), net of all out-of-pocket costs and expenses; provided, that the Borrower agrees to promptly return any such refund (plus interest) to
such Lender in the event such Lender is required to repay such refund to the relevant taxing authority. Any such Lender shall provide the Borrower with a copy of any notice of assessment from the relevant taxing authority (redacting any unrelated
confidential information contained therein) requiring repayment of such refund. Nothing contained herein shall impose an obligation on any Lender to apply for any such refund. 
  
 6.5. Late Charges. If any principal of any Loan is not paid within 10 days after the Administrative Agent
shall have given the Borrower notice of demand for the payment of the same or within 10 days after any Event of Default described in section 11.1(g) in respect of the Borrower shall have occurred, or if any interest on any Loan is not paid within 10
days after the same becomes due, then and in any such case the Administrative Agent shall have the right to assess a late charge, payable by the Borrower upon demand, in an amount equal to the greater of $20.00 or 3% of the amount not
timely paid. Any such late charge shall be for the account of the Lenders for the benefit of whom such amount was not timely paid and shall be in addition to any other amounts payable by the Borrower under the Credit Documents.

 - 54 - 








 
Borrower and its consolidated subsidiaries as of December 31, 2003 and the related unaudited condensed consolidated statements of income and of cash flows of
the Borrower and its consolidated subsidiaries for the fiscal year then ended. All such financial statements have been prepared in accordance with GAAP, consistently applied (except as stated therein), and fairly present the financial position of
the Borrower and its consolidated subsidiaries as of the respective dates indicated and the consolidated results of their operations and cash flows for the respective periods indicated, subject in the case of any such financial statements that are
unaudited, to normal audit adjustments, none of which will involve a Material Adverse Effect. 
  
 (b) The Borrower has delivered or caused to be delivered to the Lenders prior to the execution and delivery of this Agreement: (i) a copy of the Borrower’s Report on Form 10-K as filed (without
Exhibits) with the SEC for its fiscal year ended on or nearest to December 31, 2002, that contains a general description of the business and affairs of the Borrower and its Subsidiaries; and (ii) financial projections prepared by management of the
Borrower for the Borrower and its Subsidiaries for the fiscal years 2004-2006 (the “Financial Projections”). The Financial Projections were prepared on behalf of the Borrower in good faith after taking into account the
existing and historical levels of business activity of the Borrower and its Subsidiaries, known trends, including general economic trends, and all other information, assumptions and estimates considered by management of the Borrower and its
Subsidiaries to be pertinent thereto. The Financial Projections were considered by management of the Borrower, as of such date of preparation, to be realistically achievable; provided, that no representation or warranty is made as to
the impact of future general economic conditions or as to whether the Borrower’s projected consolidated results as set forth in the Financial Projections will actually be realized. No facts are known to the Borrower at the date hereof that, if
reflected in the Financial Projections, would result in a material adverse change in the assets, liabilities, results of operations or cash flows reflected therein. 
  
 8.9. No Material Adverse Change. Except as reflected in the financial statements delivered pursuant to section
8.8(a) hereof, since December 31, 2002, there has been no change in the condition, business or affairs of the Borrower and its Subsidiaries taken as a whole, or their properties and assets considered as an entirety, except for changes, none of
which, individually or in the aggregate, has had or could reasonably be expected to have, a Material Adverse Effect. 
  
 8.10. Tax Returns and Payments. Each of the Borrower and each of its Subsidiaries has filed all federal income tax returns and all other
material tax returns, domestic and foreign, required to be filed by it and has paid all material taxes and assessments payable by it that have become due, other than those not yet delinquent and except for those contested in good faith. The Borrower
and each of its Subsidiaries has established on its books such charges, accruals and reserves in respect of taxes, assessments, fees and other governmental charges for all fiscal periods as are required by GAAP. The Borrower knows of no proposed
assessment for additional federal, foreign or state taxes for any period, or of any basis therefor, that, individually or in the aggregate, taking into account such charges, accruals and reserves in respect thereof as the Borrower and its
Subsidiaries have made, could reasonably be expected to have a Material Adverse Effect. 
  
 8.11. Title to Properties, etc. The Borrower and each of its Subsidiaries has good and marketable title, in the case of real property, and good title (or valid Leaseholds, in the case of any leased
property), in the case of all other property, to all of its properties and assets free and clear of Liens other than Liens permitted by section 10.3. The interests of the Borrower and each of its Subsidiaries in the properties reflected in the most
recent balance sheet referred to in section 8.8, taken as a whole, were sufficient, in the judgment of the Borrower, as of the date of such balance sheet for purposes of the ownership and operation of the businesses conducted by the Borrower and
such Subsidiaries. 
  
 8.12. Lawful Operations, etc.
The Borrower and each of its Subsidiaries: (i) holds all necessary federal, state and local governmental licenses, registrations, certifications, permits and 

  

 - 55 - 








 
authorizations necessary to conduct its business; and (ii) is in full compliance with all material requirements imposed by law, regulation or rule, whether
federal, state or local, that are applicable to it, its operations, or its properties and assets, including without limitation, applicable requirements of Environmental Laws, except for any failure to obtain and maintain in effect, or
noncompliance, that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. 
  
 8.13. Environmental Matters. Except as set forth on Annex XI hereto: 
  
 (a) The Borrower and each of its Subsidiaries is in compliance with all Environmental Laws governing its
business, except to the extent that any such failure to comply (together with any resulting penalties, fines or forfeitures) would not reasonably be expected to have a Material Adverse Effect. All licenses, permits, registrations or
approvals required for the conduct of the business of the Borrower and each of its Subsidiaries under any Environmental Law have been secured and the Borrower and each of its Subsidiaries is in substantial compliance therewith, except
for such licenses, permits, registrations or approvals the failure to secure or to comply therewith is not reasonably likely to have a Material Adverse Effect. Neither the Borrower nor any of its Subsidiaries has received written notice, or
otherwise knows, that it is in any respect in noncompliance with, breach of or default under any applicable writ, order, judgment, injunction, or decree to which the Borrower or such Subsidiary is a party or that would affect the ability of the
Borrower or such Subsidiary to operate any Real Property and no event has occurred and is continuing that, with the passage of time or the giving of notice or both, would constitute noncompliance, breach of or default thereunder,
except in each such case, such noncompliance, breaches or defaults as would not reasonably be expected to, in the aggregate, have a Material Adverse Effect. There are no Environmental Claims pending or, to the best knowledge of the
Borrower, threatened wherein an unfavorable decision, ruling or finding would reasonably be expected to have a Material Adverse Effect. There are no facts, circumstances, conditions or occurrences on any Real Property now or at any time owned,
leased or operated by the Borrower or any of its Subsidiaries or on any property adjacent to any such Real Property, that are known by the Borrower or as to which the Borrower or any such Subsidiary has received written notice, that could reasonably
be expected: (i) to form the basis of an Environmental Claim against the Borrower or any of its Subsidiaries or any Real Property of the Borrower or any of its Subsidiaries; or (ii) to cause such Real Property to be subject to any restrictions on
the ownership, occupancy, use or transferability of such Real Property under any Environmental Law, except in each such case, such Environmental Claims or restrictions that individually or in the aggregate would not reasonably be expected to have a
Material Adverse Effect. 
  
 (b) Hazardous Materials
have not at any time been: (i) generated, used, treated or stored on, or transported to or from, any Real Property of the Borrower or any of its Subsidiaries; or (ii) released on any such Real Property, in each case where such occurrence or event is
not in compliance with Environmental Laws and is reasonably likely to have a Material Adverse Effect. 
  
 8.14. Compliance with ERISA. Compliance by the Borrower with the provisions hereof and Loans contemplated hereby will not involve any
prohibited transaction within the meaning of ERISA or section 4975 of the Code. The Borrower and each of its Subsidiaries: (i) has fulfilled all obligations under minimum funding standards of ERISA and the Code with respect to each Plan that is not
a Multiemployer Plan or a Multiple Employer Plan; (ii) has satisfied all respective contribution obligations in respect of each Multiemployer Plan and each Multiple Employer Plan; (iii) is in compliance in all material respects with all other
applicable provisions of ERISA and the Code with respect to each Plan, each Multiemployer Plan and each Multiple Employer Plan; and (iv) has not incurred any liability under the Title IV of ERISA to the PBGC with respect to any Plan, any
Multiemployer Plan, any Multiple Employer Plan, or any trust established thereunder, except for PBGC premiums in the ordinary course. No Plan or trust created thereunder has been terminated, and there have been no Reportable Events, with respect to
any Plan or trust created thereunder or with respect to any Multiple Employer Plan, which termination or Reportable Event will or could result in the termination of such Plan or Multiple Employer 

  

 - 56 - 








 
Plan and give rise to a material liability of the Borrower or any ERISA Affiliate in respect thereof. Neither the Borrower nor any ERISA Affiliate is at the
date hereof, or has been at any time within the two years preceding the date hereof, an employer required to contribute to any Multiemployer Plan or Multiple Employer Plan, or a “contributing sponsor” (as such term is defined in section
4001 of ERISA) in any Multiemployer Plan or Multiple Employer Plan. Neither the Borrower nor any ERISA Affiliate has any contingent liability with respect to any post-retirement “welfare benefit plan” (as such term is defined in ERISA)
except as disclosed on Annex IX hereto. 
  
 8.15.
Intellectual Property, etc. The Borrower and each of its Subsidiaries has obtained or has the right to use all material patents, trademarks, servicemarks, trade names, copyrights, licenses and other rights with respect to the foregoing necessary
for the present and planned future conduct of its business, without any known conflict with the rights of others, except for such patents, trademarks, servicemarks, trade names, copyrights, licenses and rights, the loss of which, and
such conflicts, that in any such case individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect. 
  
 8.16. Investment Company Act, etc. Neither the Borrower nor any of its Subsidiaries is subject to regulation with respect to the creation or
incurrence of Indebtedness under the Investment Company Act of 1940, as amended, the Interstate Commerce Act, as amended, the Federal Power Act, as amended, the Public Utility Holding Company Act of 1935, as amended, or any applicable state public

to any significant pending or, to the knowledge of the Borrower, threatened, unfair labor practice complaint, before the National Labor Relations Board; and (v) is subject to any significant pending or, to the knowledge of the Borrower, threatened,
grievance or significant arbitration proceeding arising out of or under any collective bargaining agreement; (vi) is subject to any significant pending or, to the knowledge of the Borrower, threatened, significant strike, labor dispute, slowdown or
stoppage; or (vii) is, to the knowledge of the Borrower, involved or subject to any union representation organizing or certification matter with respect to the employees of the Borrower or any of its Subsidiaries, except (with respect
to any matter specified in any of the above clauses), for such matters as, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. 
  
 8.18. Existing Indebtedness. Annex III sets forth a true and complete list, as of the date or dates set forth
therein, of all Indebtedness of the Borrower and each of its Subsidiaries, on a consolidated basis, that: (i) has an outstanding principal amount of at least $1,000,000, or may be incurred pursuant to existing commitments or lines of credit; or (ii)
is secured by any Lien on any property of the Borrower or any Subsidiary, and that will be outstanding on the Closing Date after giving effect to the initial Borrowing hereunder, other than the Indebtedness created under the Credit Documents (all
such Indebtedness, whether or not in a principal amount meeting such threshold and required to be so listed on Annex III, herein the “Existing Indebtedness”). As and to the extent the Administrative Agent has so requested,
the Borrower has provided to the Administrative Agent prior to the date of execution hereof true and complete copies (or summary descriptions) of all agreements and instruments governing the Indebtedness listed on Annex III (the “Existing
Indebtedness Agreements”).

other such factual information (taken as a whole) hereafter furnished by or on behalf of such person in writing to any Lender will be, true and accurate in all material respects on the date as of which such information is dated or certified and not
incomplete by omitting to state any material fact necessary to make such information (taken as a whole) not misleading at such time in light of the circumstances under which such information was provided, except that any such future information
consisting of financial projections prepared by management of the Borrower is only represented herein as being based on good faith estimates and assumptions believed by such persons to be reasonable at the time made, it being recognized by the
Lenders that such projections as to future events are not to be viewed as facts and that actual results during the period or periods covered by any such projections may differ materially from the projected results. As of the Effective Date, there is
no fact known to the Borrower or any of its Subsidiaries that has, or could reasonably be expected to have, a Material Adverse Effect that has not theretofore been disclosed in writing to the Lenders. 
  
 8.20. Insurance. The Borrower and each of its Subsidiaries
maintains insurance coverage by such insurers and in such forms and amounts and against such risks as are generally consistent with industry standards.

extent considered reasonably necessary by the Borrower, but without exposing the Borrower or its Subsidiaries to predominantly speculative risks unrelated to the amount of assets, Indebtedness or other liabilities intended to be subject to coverage
on a notional basis under all such Hedge Agreements. 
  
 9.11. Most Favored Covenant Status. Should the Borrower at any time after the Effective Date, issue or guarantee any unsecured Indebtedness denominated in U.S. dollars for money borrowed or represented by bonds, notes,
debentures or similar securities in an aggregate amount exceeding $2,500,000, to any lender or group of lenders acting in concert with one another, or one or more institutional investors, pursuant to a loan agreement, credit agreement, note purchase
agreement, indenture, guaranty or other similar instrument, which agreement, indenture, guaranty or instrument, includes affirmative or negative business or financial covenants (or any events of default or other type of restriction that would have
the practical effect of any affirmative or negative business or financial covenant, including, without limitation, any “put” or mandatory prepayment of such Indebtedness upon the occurrence of a “change of control”) that are
applicable to the Borrower, other than those set forth herein or in any of the other Credit Documents, the Borrower shall promptly so notify the Administrative Agent and the Lenders and, if the Administrative Agent shall so request by written notice
to the Borrower (after a determination has been made by the Required Lenders that any of the above-referenced documents or instruments contain any such provisions, that either individually or in the aggregate, are more favorable to the holders of
such unsecured Indebtedness than any of the provisions set forth herein), the Borrower, the Administrative Agent and the Lenders shall promptly amend this Agreement to incorporate some or all of such provisions, in the discretion of the
Administrative Agent and the Required Lenders, into this Agreement and, to the extent necessary and reasonably desirable to the Administrative Agent and the Required Lenders, into any of the other Credit Documents, all at the election of the
Administrative Agent and the Required Lenders. Except with respect to those documents set forth on Annex X hereto, the Borrower covenants and agrees that no later than 30 days after the date hereof, the Borrower shall have caused any document
relating to any Indebtedness that would violate the provisions of this section 9.11 to be: (a) amended so that such document no longer violates the provisions of this section 9.11, provided that any such amendment shall be reasonably
satisfactory to the Administrative Agent; or (b) terminated. 
  
 9.12. Senior Debt. The Borrower will at all times ensure that: (a) the claims of the Lenders in respect of the Obligations of the Credit Parties will not be subordinate to, and will in all respects at least rank pari
passu with, the claims of every other senior unsecured creditor of the Credit Parties; and (b) any Indebtedness subordinated in any manner to the claims of any other senior unsecured creditor of the Credit Parties will be subordinated in
like manner to such claims of the Lenders. 
  
 9.13. Certain
Subsidiaries to Join in Subsidiary Guaranty. (a) In the event that at any time after the Closing Date 
  
 (x) the Borrower has any Subsidiary (other than a Subsidiary that is a Non-Material Subsidiary and other than a Foreign Subsidiary as to
which section 9.13(b) applies) that is not a party to the Subsidiary Guaranty, or 
  

 - 63 - 








 (y) an Event of Default shall have occurred and be continuing and the Borrower has any
Subsidiary that is not a party to the Subsidiary Guaranty, 
  
 the Borrower will
notify the Administrative Agent in writing of such event, identifying the Subsidiary in question and referring specifically to the rights of the Administrative Agent and the Lenders under this section. The Borrower will, within 30 days following
request therefor from the Administrative Agent (who may give such request on its own initiative or upon request by the Required Lenders), cause such Subsidiary to deliver to the Administrative Agent, in sufficient quantities for the Lenders, (i) a
joinder supplement, reasonably satisfactory in form and substance to the Administrative Agent and the Required Lenders, duly executed by such Subsidiary, pursuant to which such Subsidiary joins in the Subsidiary Guaranty as a guarantor thereunder,
and (ii) resolutions of the Board of Directors (or similar governing body) of such Subsidiary, certified by the Secretary or an Assistant Secretary of such Subsidiary as duly adopted and in full force and effect, authorizing the execution and
delivery of such joinder supplement, or if such Subsidiary is not a corporation, such other evidence of the authority of such Subsidiary to execute such joinder supplement as the Administrative Agent may reasonably request. 
  
 (b) Notwithstanding the foregoing provisions of this section
9.13 or the provisions of any other Credit Document, the Borrower shall not, unless an Event of Default shall have occurred and be continuing, be required to cause a Foreign Subsidiary to join in the Subsidiary Guaranty or to become a party to any
other Credit Document.

 SECTION 12.
THE ADMINISTRATIVE AGENT. 
  
 12.1. Appointment.
Each Lender hereby irrevocably designates and appoints NCB as Administrative Agent to act as specified herein and in the other Credit Documents, and each such Lender hereby irrevocably authorizes NCB as the Administrative Agent for such Lender, to
take such action on its behalf under the provisions of this Agreement and the other Credit Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the
other Credit Documents, together with such other powers as are reasonably incidental thereto. The Administrative Agent agrees to act as such upon the express conditions contained in this section 12. Notwithstanding any provision to the contrary
elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein or in the other Credit Documents, nor any fiduciary relationship with any Lender, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or otherwise exist against the Administrative Agent. The provisions of this section 12 are solely for the benefit of the Administrative Agent, and the
Lenders, and the Borrower and its Subsidiaries shall not have any rights as a third party beneficiary of any of the provisions hereof. In performing its functions and duties under this Agreement, the Administrative Agent shall act solely as agent of
the Lenders and does not assume and shall not be deemed to have assumed any obligation or relationship of agency or trust with or for the Borrower or any of its Subsidiaries. 
  
 12.2. Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any
other Credit Document by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any
agents or attorneys-in-fact selected by it with reasonable care except to the extent otherwise required by section 12.3. 
  
 12.3. Exculpatory Provisions. Neither the Administrative Agent nor any of its respective officers, directors, employees, agents,
attorneys-in-fact or affiliates shall be: (i) liable for any action lawfully taken or omitted to be taken by it or such person under or in connection with this Agreement (except for its or such person’s own gross negligence or willful
misconduct); or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by the Borrower or of its Subsidiaries or any of their respective officers contained in this Agreement, any other
Credit Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Credit Document or for any failure of the
Borrower or any Subsidiary of the Borrower or any of their respective officers to perform its obligations hereunder or thereunder. The Administrative Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions of, this Agreement, or to inspect the properties, books or records of the Borrower or any of its Subsidiaries. The Administrative Agent shall not be responsible to any
Lender for the effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this Agreement or any Credit Document or for any representations, warranties, recitals or statements made herein or therein or made in any written
or oral statement or in any financial or other statements, instruments, reports, certificates or any other documents in connection herewith or therewith furnished or made by the Administrative Agent to the Lenders or by or on behalf of the Borrower
or any of its Subsidiaries to the Administrative Agent or any Lender or be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained 

  

 - 74 - 








 
herein or therein or as to the use of the proceeds of the Loans or of the existence or possible existence of any Default or Event of Default. 
  
 12.4. Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, facsimile transmission, telex or teletype message, statement, order
or other document or conversation believed by it, in good faith, to be genuine and correct and to have been signed, sent or made by the proper person or persons and upon advice and statements of legal counsel (including, without limitation, counsel
to the Borrower or any of its Subsidiaries), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any
other Credit Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be
incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Credit Documents in accordance with
a request of the Required Lenders (or all of the Lenders, as to any matter that, pursuant to section 13.12, can only be effectuated with the consent of all Lenders), and such request and any action taken or failure to act pursuant thereto shall be
binding upon all the Lenders. 
  
 12.5. Notice of
Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Administrative Agent has received notice from a Lender or the Borrower referring to this
Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give prompt notice thereof to
the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders, provided that unless and until the Administrative Agent shall have
received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the
Lenders. 
  
 12.6. Non-Reliance. Each Lender
expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates have made any representations or warranties to it and that no act by the Administrative Agent
hereinafter taken, including any review of the affairs of the Borrower or any of its Subsidiaries, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative Agent, or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business,
assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower and its Subsidiaries and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that
it will, independently and without reliance upon the Administrative Agent, or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions
in taking or not taking action under this Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the
Borrower and its Subsidiaries. The Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, assets, property, financial and other conditions,
prospects or creditworthiness of the Borrower or any of its Subsidiaries that may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates. 
  

 - 75 - 








 12.7. Indemnification. The Lenders agree to indemnify the Administrative Agent in its
capacity as such ratably according to their respective General Revolving Loans and Unutilized General Revolving Commitments, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs,
reasonable expenses or disbursements of any kind whatsoever that may at any time (including, without limitation, at any time following the payment of the Obligations) be imposed on, incurred by or asserted against the Administrative Agent in its
capacity as such in any way relating to or arising out of this Agreement or any other Credit Document, or any documents contemplated by or referred to herein or the transactions contemplated hereby or any action taken or omitted to be taken by the
Administrative Agent under or in connection with any of the foregoing, but only to the extent that any of the foregoing is not paid by the Borrower, provided that no Lender shall be liable to the Administrative Agent for the payment of
any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements to the extent resulting solely from the Administrative Agent’s gross negligence or willful misconduct. If any
indemnity furnished to the Administrative Agent for any purpose shall, in the opinion of the Administrative Agent, be insufficient or become impaired, the Administrative Agent may call for additional indemnity and cease, or not commence, to do the
acts indemnified against until such additional indemnity is furnished. The agreements in this section 12.7 shall survive the payment of all Obligations. 
  
 12.8. The Administrative Agent in Individual Capacity. The Administrative Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrower, its Subsidiaries and their Affiliates as though not acting as Administrative Agent hereunder. With respect to the Loans made by it and all Obligations owing to it, the Administrative
Agent shall have the same rights and powers under this Agreement as any Lender and may exercise the same as though it were not the Administrative Agent, and the terms “Lender” and “Lenders” shall include the Administrative Agent
in its individual capacity. 
  
 12.9. Successor
Administrative Agent. The Administrative Agent may resign as the Administrative Agent upon not less than 30 Business Days’ notice to the Lenders and the Borrower. The Administrative Agent may be removed as the Administrative Agent for cause
upon not less than 30 Business Days’ notice to the Administrative Agent and the Borrower from the Required Lenders. The Required Lenders shall appoint from among the Lenders a successor Administrative Agent for the Lenders, subject to prior
approval by the Borrower if no Event of Default has occurred and is continuing (such approval not to be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and
the term “Administrative Agent” shall include such successor agent effective upon its appointment, and the resigning or removed Administrative Agent’s rights, powers and duties as the Administrative Agent shall be terminated, without
any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement. After the retiring or removed Administrative Agent’s resignation or removal hereunder as the Administrative Agent, the
provisions of this section 12 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement. 
  
 12.10. Other Agents. Any Lender identified herein as a Co-Agent, Syndication Agent, Documentation Agent,
Managing Agent, Manager or any other corresponding title, other than “Administrative Agent,” shall have no right, power, obligation, liability, responsibility or duty under this Agreement or any other Credit Document except those
applicable to all Lenders as such. Each Lender acknowledges that it has not relied, and will not rely, on any Lender so identified in deciding to enter into this Agreement or in taking or not taking any action hereunder.

transactions solely involving the assignment by a Lender of all or a portion of its Loans and Commitments, or the granting of participations therein, as provided in this Agreement, or arising solely out of any examination of a Lender by any
regulatory or other governmental authority having jurisdiction over it; or 
  
 (ii) the actual or alleged presence of Hazardous Materials in the air, surface water or groundwater or on the surface or subsurface of any Real Property owned, leased or at any time operated by the Borrower or any of

 and, provided further, that such transfer or assignment will not be effective
until the Assignment Agreement in respect thereof is recorded by the Administrative Agent on the Lender Register maintained by it as provided herein. 
  
 To the extent of any assignment pursuant to this section 13.4(c), the assigning Lender shall be relieved of its obligations hereunder with respect to its
assigned Commitments. 
  
 At the time of each assignment pursuant
to this section 13.4(c) to a person that is not already a Lender hereunder and that is not a United States person (as such term is defined in section 7701(a)(30) of the Code) for Federal income tax purposes, the respective assignee Lender shall
provide to the Borrower and the Administrative Agent the appropriate Internal Revenue Service Forms (and, if applicable a section 6.4(b)(ii) Certificate) described in section 6.4(b). To the extent that an assignment of all or any portion of a
Lender’s Commitment and related outstanding Obligations pursuant to this section 13.4(c) would, at the time of such assignment, result in increased costs under section 2.10 from those being charged by the respective assigning Lender prior to
such assignment, then the Borrower shall not be obligated to pay such increased costs (although the Borrower shall be obligated to pay any other increased costs of the type referred to above in this sentence resulting from changes after the date of
the respective assignment). 
  
 Nothing in this section 13.4(c)
shall prevent or prohibit: (i) any Lender that is a bank, trust company or other financial institution from pledging its Notes or Loans to a Federal Reserve Bank in support of borrowings made by such Lender from such Federal Reserve Bank; or (ii)
any Lender that is a trust, limited liability company, partnership or other investment company from pledging its Notes or Loans to a trustee or agent for the benefit of holders of certificates or debt securities issued by it. No such pledge, or any
assignment pursuant to or in lieu of an enforcement of such a pledge, shall relieve the transferor Lender from its obligations hereunder. 
  
 (d) No SEC Registration or Blue Sky Compliance. Notwithstanding any other provisions of this section 13.4, no transfer or assignment of the
interests or obligations of any Lender hereunder or any grant of participation therein shall be permitted if such transfer, assignment or grant would require the 

  

 - 80 - 








 
Borrower to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any State. 
  
 (e) Representations of Lenders. Each Lender initially party to
this Agreement hereby represents, and each person that became a Lender pursuant to an assignment permitted by this section 13.4 will, upon its becoming party to this Agreement, represent that it is a commercial lender, other financial institution or
other “accredited” investor (as defined in SEC Regulation D) that makes or acquires loans in the ordinary course of its business and that it will make or acquire Loans for its own account in the ordinary course of such business,
provided that subject to the preceding sections 13.4(b) and (c), the disposition of any promissory notes or other evidences of or interests in Indebtedness held by such Lender shall at all times be within its exclusive control.

  
 (f) Grants by Lenders to SPCs. Notwithstanding
anything to the contrary contained herein, any Lender, (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting
Lender to the Administrative Agent, the Borrower and the other Lenders, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement;
provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be
obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto
hereby agrees that no SPC shall be liable for any indemnity or payment under this Agreement for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. In
furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or
other senior indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or
any State thereof. In addition, notwithstanding anything to the contrary contained in this section 13.4, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any
processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance
of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancements to such SPC. In no event shall
the Borrower be obligated to pay to an SPC that has made a Loan any greater amount than the Borrower would have been obligated to pay under this Agreement had the applicable Granting Lender made such Loan. This section 13.4(f) may not be amended
without the written consent of any Granting Lender affected thereby. 
  
 13.5. No Waiver: Remedies Cumulative. No failure or delay on the part of the Administrative Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing
between the Borrower and the Administrative Agent or any Lender shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further
exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. The rights and remedies herein expressly provided are cumulative and not exclusive of any rights or remedies that the Administrative Agent or any Lender
would otherwise have. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other 

  

 - 81 - 








 
circumstances or constitute a waiver of the rights of the Administrative Agent or any Lender to any other or further action in any circumstances without
notice or demand. 
  
 13.6. Payments Pro Rata. (a)
The Administrative Agent agrees that promptly after its receipt of each payment from or on behalf of the Borrower in respect of any Obligations, it shall distribute such payment to the Lenders (other than any Lender that has expressly waived in
writing its right to receive its pro rata share thereof) pro rata based upon their respective shares, if any, of the Obligations with respect to which such payment was received. As to any such payment received by the
Administrative Agent prior to 1:00 P.M. (local time at its Payment Office) in funds that are immediately available on such day, the Administrative Agent will use all reasonable efforts to distribute such payment in immediately available funds on the
same day to the Lenders as aforesaid. 
  
 (b) Each
of the Lenders agrees that, if it should receive any amount hereunder (whether by voluntary payment, by realization upon security, by the exercise of the right of setoff or banker’s lien, by counterclaim or cross action, by the enforcement of
any right under the Credit Documents, or otherwise) that is applicable to the payment of the principal of, or interest on, the Loans or Fees, of a sum that with respect to the related sum or sums received by other Lenders is in a greater proportion
than the total of such Obligation then owed and due to such Lender bears to the total of such Obligation then owed and due to all of the Lenders immediately prior to such receipt, then such Lender receiving such excess payment shall purchase for
cash without recourse or warranty from the other Lenders an interest in the Obligations to such Lenders in such amount as shall result in a proportional participation by all of the Lenders in such amount, provided that if all or any
portion of such excess amount is thereafter recovered from such Lender, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest. 
  
 (c) Notwithstanding anything to the contrary contained herein,
the provisions of the preceding sections 13.6(a) and (b) shall be subject to the express provisions of this Agreement that require, or permit, differing payments to be made to Lenders that are not Defaulting Lenders, as opposed to Defaulting
Lenders. 
  
 13.7. Calculations: Computations.
(a) The financial statements to be furnished to the Lenders pursuant hereto shall be made and prepared in accordance with GAAP consistently applied throughout the periods involved (except as set forth in the notes thereto or as otherwise
disclosed in writing by the Borrower to the Lenders); provided, that if at any time the computations determining compliance with section 10 utilize accounting principles different from those utilized in the financial statements
furnished to the Lenders, such computations shall set forth in reasonable detail a description of the differences and the effect upon such computations. 
  
 (b) All computations of interest on Prime Rate Loans and Eurodollar Loans hereunder and all computations of Facility Fees and other Fees
hereunder shall be made on the actual number of days elapsed over a year of 360 days. 
  
 13.8. Governing Law; Submission to Jurisdiction; Venue; Waiver of Jury Trial. (a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND
THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE COMMONWEALTH OF PENNSYLVANIA. TO THE FULLEST EXTENT PERMITTED BY LAW, THE BORROWER HEREBY UNCONDITIONALLY AND IRREVOCABLY WAIVES ANY CLAIM TO ASSERT THAT THE LAW OF
ANY JURISDICTION OTHER THAN THE COMMONWEALTH OF PENNSYLVANIA GOVERNS THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS. Any legal action or proceeding with respect to this Agreement or any other Credit Document may be brought in the Courts of the
Commonwealth of Pennsylvania, or of the United States 

  

 - 82 - 








 
for the Western District of Pennsylvania, and, by execution and delivery of this Agreement, the Borrower hereby irrevocably accepts for itself and in respect
of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. The Borrower hereby further irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the
mailing of copies thereof by registered or certified mail, postage prepaid, to the Borrower at its address for notices pursuant to section 13.3, such service to become effective 30 days after such mailing or at such earlier time as may be provided
under applicable law. Nothing herein shall affect the right of the Administrative Agent or any Lender to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Borrower in any other
jurisdiction. 
  
 (b) The Borrower hereby
irrevocably waives any objection that it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Agreement or any other Credit Document brought in the courts referred
to in section 13.8(a) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum. 
  
 (c) EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY
WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS (INCLUDING, WITHOUT LIMITATION, ANY AMENDMENTS, WAIVERS OR OTHER MODIFICATIONS RELATING
TO ANY OF THE FOREGOING), OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY HERETO HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD
NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS
PARAGRAPH. 
  
 13.9. Counterparts. This Agreement
may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same agreement. A
set of counterparts executed by all the parties hereto shall be lodged with the Borrower and the Administrative Agent. 
  
 13.10. Effectiveness; Integration. This Agreement shall become effective on the date (the “Effective Date”) on which
the Borrower and each of the Lenders shall have signed a copy hereof (whether the same or different copies) and shall have delivered the same to the Administrative Agent at the Notice Office of the Administrative Agent or, in the case of the
Lenders, shall have given to the Administrative Agent telephonic (confirmed in writing), written telex or facsimile transmission notice (actually received) at such office that the same has been signed and mailed or sent by overnight courier to it.
This Agreement, the other Credit Documents and any separate letter agreements with respect to fees payable to the Administrative Agent, for its own account and benefit and/or for the account, benefit of, and distribution to, the Lenders, constitute
the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof or thereof. 
  
 13.11. Headings Descriptive. The headings of the several
sections and other portions of this Agreement are inserted for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement. 
  

 - 83 - 








 13.12. Amendment or Waiver. Neither this Agreement nor any terms hereof or thereof may be
amended, waived or otherwise modified unless such amendment, waiver or other modification is in writing and signed by the Borrower and the Required Lenders, provided that no such amendment, waiver or other modification
shall, without the consent of each Lender (other than a Defaulting Lender) affected thereby: 
  
 (a) extend any final date on or by which any Loan to be made by such Lender may be incurred, or on which any such Loan is scheduled to be repaid (but not prepaid) or mature, or extend any date on or by
which any interest or fees payable hereunder are scheduled to be paid, or extend any final date on which any Commitment of such Lender is scheduled to expire or terminate or increase any such Lender’s General Revolving Commitment or extend the
expiration date of any Letter of Credit as to which such Lender is a Participant pursuant to section 3.4 beyond the latest expiration date for a Letter of Credit provided for herein, or reduce the rate of interest or Fees thereon (except in
connection with a waiver of the applicability of any post-default increase in interest rates), or reduce the principal amount thereof. 
  
 (b) amend, modify or waive any provision of this section 13.12, or section 12.7, 13.4, 13.6 or 13.7(b), or any other provision of any of the
Credit Documents pursuant to which the consent or approval of all Lenders is by the terms of such provision explicitly required; 
  
 (c) reduce the percentage specified in, or otherwise modify, the definition of Required Lenders; 
  
 (d) release any Material Subsidiary from the Subsidiary
Guaranty; or 
  
 (e) consent to the assignment or
transfer by the Borrower of any of its rights and obligations under this Agreement. 
  
 No provision of section 12 may be amended without the consent of the Administrative Agent. 
  
 13.13. Survival. All indemnities set forth herein including, without limitation, in section 2.10, 2.11, 12.7 and 13.1, shall survive the
execution and delivery of this Agreement and the making, prepayment and repayment of Loans. 
  
 13.14. Domicile of Loans. Each Lender may transfer and carry its Loans at, to or for the account of any branch office, subsidiary or affiliate of such Lender, provided that no Borrower
shall be responsible for costs arising under section 2.10 resulting from any such transfer (other than a transfer pursuant to section 2.12) to the extent not otherwise applicable to such Lender prior to such transfer. 
  
 13.15. Confidentiality. (a) The Administrative Agent and the
Lenders agrees to maintain the confidentiality of the Confidential Information (as defined below), except that Confidential Information may be disclosed: (i) to its and its Affiliates’ directors, officers, employees and agents,
including accountants, legal counsel and other advisors (it being understood that the persons to whom such disclosure is made will be informed of the confidential nature of such Confidential Information and instructed to keep such Confidential
Information confidential); (ii) to any direct or indirect contractual counterparty in any swap, hedge or similar agreement (or to any such contractual counterparty’s professional advisor, so long as such contractual counterparty (or such
professional advisor) agrees to be bound by the provisions of this section 13.15; (iii) to the extent requested by any regulatory authority; (iv) to the extent required by applicable laws or regulations or by any subpoena or similar legal process;
(v) to any other party to this Agreement; (vi) in connection with the exercise of any remedies hereunder or under any of the other Credit Documents, or any suit, action or proceeding relating to this Agreement or any of the other Credit Documents or
the enforcement of rights hereunder or thereunder; (vii) subject to an agreement containing provisions substantially the same as those of this section 13.15, to any assignee 

  

 - 84 - 








 
of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement; (viii) with the consent of the
Borrower; or (ix) to the extent such Confidential Information (x) becomes publicly available other than as a result of a breach of this section 13.15, or (y) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from
a source other than the Borrower. 
  
 (b) For the
purposes of this section 13.15, “Confidential Information” means all information received from the Borrower relating to the Borrower and/or its Subsidiaries or their business, other than any such information that is (i)
identified at the time of delivery as non-confidential, or (ii) available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower. 
  
 (c) Any person required to maintain the confidentiality of Confidential Information as provided in this
section 13.15 shall be considered to have complied with its obligation to do so if such person has exercised the same degree of care to maintain the confidentiality of such Confidential Information as such person would accord to its own confidential
information. The Borrower hereby agrees that the failure of the Administrative Agent or any Lender to comply with the provisions of this section 13.15 shall not relieve the Borrower of any of its obligations under this Agreement or any of the other
Credit Documents. 
  
 13.16. Lender Register. The
Borrower hereby designates the Administrative Agent to serve as its agent, solely for purposes of this section 13.16, to retain a copy of each Assignment Agreement delivered to and accepted by it and to maintain a register (the “Lender
Register”) on or in which it will record the names and addresses of the Lenders, and the Commitments from time to time of each of such Lenders to the Borrower, the Loans made to the Borrower by each of such Lenders and each repayment
and prepayment in respect of the principal amount of such Loans of each such Lender. Failure to make any such recordation, or (absent manifest error) any error in such recordation, shall not affect the Borrower’s obligations in respect of such
Loans. With respect to any Lender, the transfer of any Commitment of such Lender and the rights to the principal of, and interest on, any Loan made pursuant to such Commitment shall not be effective until such transfer is recorded on the Lender
Register maintained by the Administrative Agent with respect to ownership of such Commitment and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitment and Loans shall remain owing to the transferor.
The registration of assignment or transfer of all or part of any Commitment and Loans shall be recorded by the Administrative Agent on the Lender Register only upon the acceptance by the Administrative Agent of a properly executed and delivered
Assignment Agreement pursuant to section 13.4(c). The Borrower agrees to indemnify the Administrative Agent from and against any and all losses, claims, damages and liabilities of whatsoever nature that may be imposed on, asserted against or
incurred by the Administrative Agent in performing its duties under this section 13.16. The Lender Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

  
 13.17. General Limitation of Liability. No claim
may be made by the Borrower, any Lender or the Administrative Agent or any other person against the Administrative Agent or any other Lender or the Affiliates, directors, officers, employees, attorneys or agents of any of them, for any damages other
than actual compensatory damages in respect of any claim for breach of contract or any other theory of liability arising out of or related to the transactions contemplated by this Agreement or any of the other Credit Documents, or any act, omission
or event occurring in connection therewith, and the Borrower, each Lender and the Administrative Agent hereby, to the fullest extent permitted under applicable law, waives, releases and agrees not to sue or counterclaim upon any such claim for any
special, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor. 
  
 13.18. No Duty. All attorneys, accountants, appraisers, consultants and other professional persons (including the firms or other entities on
behalf of which any such person may act) retained by the 

  

 - 85 - 








 
Administrative Agent or any Lender with respect to the transactions contemplated by the Credit Documents shall have the right to act exclusively in the
interest of the Administrative Agent or such Lender, as the case may be, and shall have no duty of disclosure, duty of loyalty, duty of care, or other duty or obligation of any type or nature whatsoever to the Borrower, to any of its Subsidiaries or
Affiliates, or to any other person, with respect to any matters within the scope of such representation or related to their activities in connection with such representation. The Borrower agrees, on behalf of itself and its Subsidiaries, not to
assert any claim or counterclaim against any such persons with regard to such matters, all such claims and counterclaims, now existing or hereafter arising, whether known or unknown, foreseen or unforeseeable, being hereby waived, released and
forever discharged. 
  
 13.19. Lenders and Agents Not
Fiduciary to Borrower, etc. The relationship among the Borrower and its Subsidiaries and Affiliates, on the one hand, and the Administrative Agent and the Lenders, on the other hand, is solely that of debtor and creditor, and the Administrative
Agent and the Lenders have no fiduciary or other special relationship with the Borrower and/or any of its Subsidiaries and Affiliates, and no term or provision of any Credit Document, no course of dealing, no written or oral communication, or other
action, shall be construed so as to deem such relationship to be other than that of debtor and creditor. 
  
 13.20. Survival of Representations and Warranties. All representations and warranties herein shall survive the making of Loans hereunder,
the execution and delivery of this Agreement, the Notes and any other documents the forms of which are attached as Exhibits hereto, the issue and delivery of the Notes, any disposition thereof by any holder thereof, and any investigation made by the
Administrative Agent or any Lender or any other holder of any of the Notes or on its behalf. All statements contained in any certificate or other document delivered to the Administrative Agent or any Lender or any holder of any Notes by or on behalf
of the Borrower or any of its Subsidiaries or Affiliates pursuant hereto or otherwise specifically for use in connection with the transactions contemplated hereby shall constitute representations and warranties by the Borrower hereunder, made as of
the respective dates specified therein or, if no date is specified, as of the respective dates furnished to the Administrative Agent or any Lender. 
  
 13.21. Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action, event, condition
or circumstance is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations or restrictions of, another covenant, shall not avoid the occurrence of a Default or an
Event of Default if such action is taken or event, condition or circumstance exists.

best of the Borrower’s knowledge, the fair value of the property and assets of the Borrower is greater than the total amount of liabilities (including contingent, subordinated, absolute, fixed, matured or unmatured and liquidated or
unliquidated liabilities) of the Borrower. 
  
 2. On the date
hereof, the present fair salable value of the property and assets of the Borrower exceeds the amount that will be required to pay the probable liabilities of the Borrower on its debts as they become absolute and matured. 
  
 3. The Borrower does not currently intend or believe that it will incur debts
and liabilities that will be beyond its ability to pay as such debts and liabilities mature. 
  
 4. On the date hereof, the Borrower is not engaged in business or in a transaction, and is not about to engage in business or in a transaction, for that its property and assets would constitute unreasonably small
capital. 
  
 5. The Borrower does not intend to hinder, delay or
defraud either present or future creditors or any other person to which the Borrower is or, on or after the date hereof, will become indebted. 
  









 IN WITNESS WHEREOF, the Borrower has caused this Solvency Certificate to be executed by its Chief
Financial Officer thereunto duly authorized, on and as of this 18th day of February, 2004.

ENVIRONMENTAL MATTERS 
  
 Waterlink - Barnebey Sutcliffe Facility 
 835
North Cassaday Street 
 Columbus, Ohio 
  
 There are several environmental conditions identified at the Waterlink-Barnebey Sutcliffe (“WBS”) facility in Columbus, Ohio. Soils and
groundwater in several areas are contaminated with one or more volatile organic compounds, semi-volatile organic compounds and/or metals. The most significant of such areas is the former drum storage area where dense nonaqueous phase liquids
(“DNAPLs”) have been identified. There are also approximately 3,000 cubic yards of spent activated carbon stockpiled in this area that must be disposed. Adjacent to the southeast of this area is a captive landfill site that may require
additional investigation and possibly remediation. WBS’s consultant, Clayton Group Services (located in Akron, Ohio) estimates remediation costs for the soil and groundwater contamination in the former drum storage area to be between
approximately $2.2 and $2.6 million. Calgon Carbon Corporation’s consultant, KU Resources (Duquesne, Pennsylvania) estimates remediation of this and other impacted areas at the facility could cost between $5.3 and $7.3 million, although less
expensive remedial options may be available.

 SUBSIDIARY GUARANTY, dated as of February 18, 2004 (as amended, modified or supplemented from time to time,
“this Guaranty”), made by (i) each of the undersigned (each, together with its successors and assigns, a “Guarantor” and collectively, the “Guarantors”), with (ii) NATIONAL
CITY BANK OF PENNSYLVANIA, a national banking association, as Administrative Agent (herein, together with its successors and assigns in such capacity, the “Administrative Agent”), for the benefit of the Creditors
(as defined below): 
  
 PRELIMINARY STATEMENTS: 

 
 (1) Except as otherwise defined herein, terms used herein and defined in
the Credit Agreement (as defined below) shall be used herein as therein defined. Certain terms used herein are defined in section 1 hereof. 
  
 (2) This Guaranty is made pursuant to the Credit Agreement, dated as of the date hereof (herein, as amended or otherwise modified, restated or replaced
from time to time, the “Credit Agreement”), among Calgon Carbon Corporation, a Delaware corporation (herein, together with its successors and assigns, the “Company” or a
“Borrower”), the financial institutions named as lenders therein (herein, together with any other person that becomes a “Lender” under the Credit Agreement and the respective successors and assigns of such lenders
and “Lenders”, the “Lenders”), and the Administrative Agent. 
  
 (3) The Credit Agreement provides, among other things, for loans or advances or other extensions of credit to or for the benefit of the Borrower of up to $125,000,000, with such loans or advances being evidenced by
promissory notes (the “Notes”, such term to include all notes and other securities issued in exchange therefor or in replacement thereof). The Credit Agreement also provides that one or more Letter of Credit Issuers may issue
Letters of Credit for the benefit of the Borrower and/or any of its Subsidiaries, and that the Lenders will risk participate in such Letters of Credit. 
  
 (4) The Company or any of its Subsidiaries may from time to time be party to one or more Designated Hedge Agreements (as defined in the Credit Agreement)
and other Designated Hedge Documents (as defined herein). Any institution or other person that participates, and in each case their successors and assigns, as a counterparty to the Company or any of its Subsidiaries or Affiliates pursuant to any

shall have executed and delivered this Guaranty. 
  
 (8) Each
Guarantor will obtain benefits from the incurrence of the Credit Document Obligations and the Designated Hedge Document Obligations (as such terms are hereafter defined) and, accordingly, desires to execute this Guaranty in order to satisfy the
condition described in the preceding paragraph and to induce the Creditors to extend the Credit Document Obligations and the Designated Hedge Document Obligations. 
  









 NOW, THEREFORE, in consideration of the foregoing and other benefits accruing to each Guarantor,
the receipt and sufficiency of which are hereby acknowledged, each Guarantor hereby makes the following representations and warranties to the Administrative Agent and the other Creditors and hereby covenants and agrees with the Administrative Agent
and each other Creditor as follows: 
  

	1.	Certain Definitions. As used in this Guaranty, the following terms shall have the meanings herein specified unless the context otherwise requires:


  
 “Credit Document
Obligations” shall mean and include: 
  

	 	(i)	the principal of and interest on the Notes issued by, and the Loans made to, the Borrower under the Credit Agreement, 

  

	 	(ii)	all reimbursement obligations and Unpaid Drawings with respect to Letters of Credit issued under the Credit Agreement, and 

  

	 	(iii)	all other obligations and liabilities owing by the Borrower and the other Credit Parties to the Administrative Agent, any Letter of Credit Issuer or any of the Lenders under the
Credit Agreement and the other Credit Documents to which the Borrower or any other Credit Party is now or may hereafter become a party (including, without limitation, indemnities, Fees and other amounts payable thereunder), whether primary,
secondary, direct, contingent, fixed or otherwise, 

  
 in all cases
whether now existing, or hereafter incurred or arising, including any such interest or other amounts incurred or arising during the pendency of any bankruptcy, insolvency, reorganization, receivership or similar proceeding, regardless of whether
allowed or allowable in such proceeding or subject to an automatic stay under section 362(a) of the Bankruptcy Code. 
  
 “Designated Hedge Document” shall mean and include (i) each Designated Hedge Agreement to which the Company or any of its
Subsidiaries or Affiliates is now or may hereafter become a party, and (ii) each confirmation, transaction statement or other document executed and delivered in connection therewith to which the Company or any of its Subsidiaries or Affiliates is
now or may hereafter become a party. 
  
 “Designated
Hedge Document Obligations” shall mean and include all obligations and liabilities owing by the Company or any of its Subsidiaries or Affiliates under all existing and future Designated Hedge Documents, in all cases whether now
existing, or hereafter incurred or arising, including any such amounts incurred or arising during the pendency of any bankruptcy, insolvency, reorganization, receivership or similar proceeding, regardless of whether allowed or allowable in such
proceeding or subject to an automatic stay under section 362(a) of the Bankruptcy Code. 
  
 “Guaranteed Documents” shall mean and include (i) the Credit Agreement, the Notes and the other Credit Documents to which the Borrower or any of its Subsidiaries or Affiliates is
now or may hereafter become a party, and (ii) each Designated Hedge Agreement and other Designated Hedge Document to which the Company or any of its Subsidiaries or Affiliates is now or may hereafter become a party. 
  
 “Guaranteed Obligations” shall mean and
include the Credit Document Obligations and the Designated Hedge Document Obligations. 
  

	2.	Guaranty by the Guarantors, etc. (a) Each Guarantor, jointly and severally, irrevocably and unconditionally guarantees: 

  

	 	(i)	to the Administrative Agent, each Letter of Credit Issuer and the Lenders the full and prompt payment when due (whether at the stated maturity, by acceleration or otherwise) of all
of the Credit Document Obligations of (1) the Borrower, and (2) each of the other Subsidiaries and Affiliates of the Borrower which is a Credit Party; and 

  

	 	(ii)	to each Designated Hedge Creditor the full and prompt payment when due (whether at the stated maturity, by acceleration or otherwise) of all of the Designated Hedge Document
Obligations of (1) the Company, and (2) each of the other Subsidiaries and Affiliates of the Company. 

  
 Such guaranty is an absolute, unconditional, present and continuing guaranty of payment and not of collectibility and is in no way conditioned or contingent upon any
attempt to collect from the Borrower or any other Subsidiary or Affiliate 

  

 2 








 
of the Borrower, or any other action, occurrence or circumstance whatsoever. If an Event of Default shall occur and be continuing under the Credit Agreement
or any payment default shall occur and be outstanding under any Designated Hedge Document beyond any applicable notice or grace period, each Guarantor will, within two Business Days following its receipt of written notice from the Administrative
Agent demanding payment hereunder, pay to the Administrative Agent, for the benefit of the Creditors, in immediately available funds, at the Payment Office of the Administrative Agent, such amount of the Guaranteed Obligations as the Administrative
Agent shall specify in such notice, on the same terms as applicable to the Guaranteed Obligations. 
  

	 	(b)	In addition to the foregoing, each Guarantor also, jointly and severally, irrevocably and unconditionally guarantees that each of the terms, conditions, covenants and agreements of
the Borrower under the Credit Agreement, and of the Borrower and its other Subsidiaries and Affiliates under the other Guaranteed Documents, will be duly and punctually performed and observed strictly in accordance with the terms thereof and that if
for any reason whatsoever the Borrower or its other Subsidiaries or Affiliates shall fail to do so (beyond any applicable grace period), such Guarantor shall duly and punctually perform and observe, or cause the Borrower or such other Subsidiary or
Affiliate, as applicable, to duly and punctually perform and observe, the same. Such guaranty is an absolute, unconditional, present and continuing guaranty of performance and is in no way conditioned or contingent upon any attempt to enforce
performance by the Company or any other Subsidiary or Affiliate of the Company, or any other act, occurrence or circumstance whatsoever. 

  

	 	(c)	In addition to the foregoing, each Guarantor, jointly and severally, unconditionally and irrevocably, guarantees to the Creditors the payment of any and all Guaranteed Obligations
of the Borrower and each of their other Subsidiaries and Affiliates, whether or not due or payable by the obligor thereon, upon the occurrence in respect of the Borrower or other applicable obligor of any bankruptcy or insolvency proceeding or case
under the Bankruptcy Code, and unconditionally and irrevocably, jointly and severally, promises to pay such Guaranteed Obligations to the Administrative Agent, for the benefit of the Creditors, on demand, in such currency and otherwise in such
manner as is provided in the Guaranteed Documents governing such Guaranteed Obligations. 

  

	 	(d)	As a separate, additional and continuing obligation, each Guarantor unconditionally and irrevocably undertakes and agrees, for the benefit of the Creditors, that, should any amounts
constituting Guaranteed Obligations not be recoverable from the Borrower or any other applicable Subsidiary or Affiliate for any reason whatsoever (including, without limitation, by reason of any provision of any Guaranteed Document or any other
agreement or instrument executed in connection therewith being or becoming, at any time, voidable, void, unenforceable, or otherwise invalid under any applicable law), then notwithstanding any notice or knowledge thereof by the Administrative Agent,
any other Creditor, any of their respective Affiliates, or any other person, each Guarantor, jointly and severally, as sole, original and independent obligor, upon demand by the Administrative Agent, will make payment to the Administrative Agent,
for the account of the Creditors, of all such obligations not so recoverable by way of full indemnity, in such currency and otherwise in such manner as is provided in the Guaranteed Documents. 

  

	 	(e)	Each Guarantor understands, agrees and confirms that the Administrative Agent and the other Creditors may enforce this Guaranty up to the full amount of the Guaranteed Obligations
against any Guarantor without proceeding against any other Guarantor, the Borrower or any other person, or against any security or other collateral. 

  

	 	(f)	All payments by each Guarantor under this Guaranty shall be made to the Administrative Agent, for the benefit of the Creditors, in such currency and otherwise in such manner as is
provided in the Guaranteed Documents to which such payments relate. 

  

	3.	 Subordination. (a) Any Indebtedness or other obligations or liabilities of the Borrower now or hereafter held by any Guarantor (collectively,
“Subordinated Obligations”) is hereby subordinated to the Indebtedness of the Borrower to any Creditor; and such Subordinated Obligations of the Borrower to any Guarantor, if the Administrative Agent, after an Event of
Default has occurred so requests, shall be collected, enforced and received by such Guarantor as trustee for the Administrative Agent and the other Creditors and be paid over to the Administrative Agent, for the benefit of the Creditors, on account
of the Indebtedness of the 



  

 3 









	 	 
Borrower to the Administrative Agent and the other Creditors, but without affecting or impairing in any manner the liability of such Guarantor under the
other provisions of this Guaranty. Prior to the transfer by any Guarantor of any note or negotiable instrument evidencing any Subordinated Obligation of the Borrower to such Guarantor, such Guarantor shall mark such note or negotiable instrument
with a legend that the same is subject to this subordination. 


  

	 	(b)	If and to the extent that any Guarantor makes any payment to the Administrative Agent or any other Creditor or to any other person pursuant to or in respect of this Guaranty, any
reimbursement or similar claim which such Guarantor may have against the Borrower by reason thereof shall be subject and subordinate to the prior termination of the Total Commitment termination or expiration of all Letters of Credit and indefeasible
payment in full of all Guaranteed Obligations owed to the Administrative Agent and the other Creditors. 

  

	4.	Guarantors’ Obligations Absolute, etc. The obligations of each Guarantor under this Guaranty shall be absolute and unconditional, shall not be subject to any
counterclaim, setoff, deduction or defense based on any claim such Guarantor may have against the Borrower or any other person, including, without limitation, the Administrative Agent, any other Creditor, any of their respective Affiliates, or any
other Guarantor, and shall remain in full force and effect without regard to, and shall not be released, suspended, abated, deferred, reduced, limited, discharged, terminated or otherwise impaired or adversely affected by any circumstance or
occurrence whatsoever, other than indefeasible payment in full of, and complete performance of, all of the Guaranteed Obligations, the termination of the Total Commitment and the termination or expiration of all Letters of Credit, including, without
limitation: 

  

	 	(1)	any increase in the amount of the Guaranteed Obligations outstanding from time to time, including, without limitation, any increase in the aggregate outstanding amount of the Loans

obligations of, a guarantor or other surety. 

  

	5.	Waivers. Each Guarantor unconditionally waives, to the maximum extent permitted under any applicable law now or hereafter in effect, insofar as its obligations under this
Guaranty are concerned, (i) notice of any of the matters referred to in section 4, (ii) all notices required by statute, rule of law or otherwise to preserve any rights against such Guarantor hereunder, including, without limitation, any demand,

	8.	Guarantors Familiar with Borrower’s Affairs, etc. Each Guarantor confirms that an executed (or conformed) copy of each of the Credit Documents has been made

 7

that no violation of any provision, covenant or agreement contained in section 8 or 9 of the Credit Agreement, and so that no Event of Default, is caused by the actions of such Guarantor or any of its Subsidiaries. 


  

	10.	Representations and Warranties. Each Guarantor represents and warrants to the Administrative Agent and each of the other Creditors that: 

  

	 	(a)	it is a duly organized or formed and validly existing corporation, partnership or limited liability company, as the case may be, in good standing under the laws of the jurisdiction
of its formation and has the corporate, partnership or limited liability company power and authority, as applicable, to own its property and assets and to transact the business in which it is engaged and presently proposes to engage;


  

	 	(b)	it has the corporate or other organizational power and authority to execute, deliver and carry out the terms and provisions of the Credit Documents to which it is party and has
taken all necessary corporate or other organizational action to authorize the execution, delivery and performance of the Credit Documents to which it is party; 

  

	 	(c)	it has duly executed and delivered each Credit Document to which it is party and each Credit Document to which it is party constitutes the legal, valid and binding agreement or
obligation of such Guarantor enforceable in accordance with its terms, except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws generally affecting
creditors’ rights and by equitable principles (regardless of whether enforcement is sought in equity or at law); 

  

	 	(d)	neither the execution, delivery and performance by such Guarantor of the Credit Documents to which it is party nor compliance with the terms and provisions thereof (i) will
contravene any provision of any law, statute, rule, regulation, order, writ, injunction or decree of any court or governmental instrumentality applicable to such Guarantor or its properties and assets, (ii) will conflict with or result in any breach
of, any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien (other than any Lien created pursuant to the Credit Documents)
upon any of the property or assets of such Guarantor pursuant to the terms of any promissory note, bond, debenture, indenture, mortgage, deed of trust, credit or loan agreement, or any other material agreement or other instrument, to which such
Guarantor is a party or by which it or any of its property or assets are bound or to which it may be subject, or (iii) will violate any provision of the certificate or articles of incorporation, code of regulations or by-laws, or other charter or
organizational documents of such Guarantor; 

  

	 	(e)	 no order, consent, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, any foreign or domestic
governmental or public body or authority, or any subdivision thereof, is required to authorize or is required as a condition to (i) the execution, delivery and performance by such Guarantor of any Credit Document to which it is a party, or (ii) the
legality, validity, binding effect or enforceability of any Credit Document to which such Guarantor is a party, other than filings and recordings necessary to establish or perfect 



  

 8 









	 	 
any security interests or other Liens created pursuant to the Credit Documents; 


  

	 	(f)	there are no actions, suits or proceedings pending or, to, the knowledge of such Guarantor, threatened with respect to such Guarantor which question the validity or enforceability
of any of the Credit Documents to which such Guarantor is a party, or of any action to be taken by such Guarantor pursuant to any of the Credit Documents to which it is a party; and 

  

	 	(g)	as of the date such Guarantor has become a party to this Guaranty, (i) such Guarantor has received consideration which is the reasonable equivalent value of the obligations and
liabilities that such Guarantor has incurred to the Administrative Agent and the other Creditors under this Guaranty and the other Credit Documents to which such Guarantor is a party; (ii) such Guarantor has capital sufficient to carry on its
business and transactions and all business and transactions in which it is about to engage and is solvent and able to pay its debts as they mature; (iii) such Guarantor owns property having a value, both at fair valuation and at present fair salable
value, greater than the amount required to pay its debts; and (iv) such Guarantor is not entering into the Credit Documents to which it is a party with the intent to hinder, delay or defraud its creditors. 

  

	11.	Continuing Guaranty; Remedies Cumulative, etc. This Guaranty is a continuing guaranty, all liabilities to which it applies or may apply under the terms hereof shall be
conclusively presumed to have been created in reliance hereon, and this Guaranty shall remain in full force and effect until terminated as provided in section 28 hereof. No failure or delay on the part of the Administrative Agent or any other
Creditor in exercising any right, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of
any other right, power or privilege. The rights and remedies herein expressly specified are cumulative and not exclusive of any rights or remedies which the Administrative Agent or any other Creditor would otherwise have. No notice to or demand on
any Guarantor in any case shall entitle such Guarantor to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Administrative Agent or any other Creditor to any other or further action in
any circumstances without notice or demand. It is not necessary for the Administrative Agent or any other Creditor to inquire into the capacity or powers of any of the Borrower or any of its Subsidiaries or the officers, directors, partners or
agents acting or purporting to act on its behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder. 

  

	12.	Application of Payments and Recoveries. All amounts received by the Administrative Agent pursuant to, or in connection with the enforcement of, this Guaranty, together
with all amounts and other rights and benefits realized by any Creditor (or to which any Creditor may be entitled) by virtue of this Guaranty, shall be applied as provided in section 11.3 of the Credit Agreement. 

  

	13.	Enforcement Expenses. The Guarantors hereby jointly and severally agree to pay, to the extent not paid pursuant to section 13.1 of the Credit Agreement, all reasonable
out-of-pocket costs and expenses of the Administrative Agent and each other Creditor in connection with the enforcement of this Guaranty and any amendment, waiver or consent relating hereto (including, without limitation, the reasonable fees and
disbursements of counsel employed by the Administrative Agent or any of the other Creditors). 

  

	14.	Successors and Assigns. This Guaranty shall be binding upon each Guarantor and its successors and assigns, and shall inure to the benefit of the Administrative Agent and the
other Creditors and their successors and assigns. 

  

	15.	Entire Agreement. This Guaranty and the other Guaranteed Documents represent the final agreement among the parties and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements among the parties. There are no unwritten oral agreements among the parties. 

  

 9 









	16.	Amendments and Waivers. Neither this Guaranty nor any provision hereof may be changed, waived, modified or varied in any manner whatsoever unless in writing duly signed by
(i) the Administrative Agent, acting with the written consent of the Required Lenders (or to the extent required by section 13.12 of the Credit Agreement, with the written consent of all of the Lenders, or all of the Lenders (other than any
Defaulting Lender), as applicable); and (ii) each Guarantor affected thereby (it being understood that the addition or release of any Guarantor hereunder shall not constitute a change, waiver, modification or variance affecting any Guarantor other
than the Guarantor so added or released), provided, however, that 

  

	 	(a)	no such change, waiver, modification or variance shall be made to section 12, section 28 or this section 16 which adversely affects any Creditor without the written consent of such
Creditor; 

  

	 	(b)	any change, waiver, modification or variance which adversely affects the rights and benefits of a single Class of Creditors (and not all Creditors in a like or similar manner) shall
require the written consent of the Requisite Creditors of such Class of Creditors; and 

  

	 	(c)	any change, waiver, modification or variance which adversely affects the rights and benefits of less than all of the members of a single Class of Creditors (and not all Creditors,
nor all Creditors of the same Class, in a like or similar manner) shall require the written consent of each of such members which is adversely affected thereby. 

  
 For the purpose of this Guaranty, the term “Class” shall mean each class of Creditors, i.e.,
whether (x) the Administrative Agent, the Collateral Agent, the Letter of Credit Issuers and the Lenders as holders of the Credit Document Obligations or (y) the Designated Hedge Creditors as holders of the Designated Hedge Obligations. For the
purpose of this Guaranty, the term “Requisite Creditors” of any Class shall mean (x) with respect to the Credit Document Obligations, the Required Lenders and (y) with respect to the Designated Hedge
Obligations, the holders of at least 51% of all Designated Hedge Obligations outstanding from time to time under the Designated Hedge Documents. 
  

	17.	Headings Descriptive. The headings of the several sections of this Guaranty are inserted for convenience only and shall not in any way affect the meaning or
construction of any provision of this Guaranty. 

  

	18.	Severability. Any provision of this Guaranty which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.


  

	19.	Right of Setoff. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence and
during the continuance of an Event of Default (such term to mean any “Event of Default” as defined in the Credit Agreement or any payment default under any Designated Hedge Document after any applicable grace period), each Creditor is
hereby authorized at any time or from time to time, without notice to any Guarantor or to any other person, any such notice being expressly waived, to set off and to appropriate and apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by such Creditor to or for the credit or the account of such Guarantor, against and on account of the obligations and liabilities of such Guarantor to such Creditor under this Guaranty, irrespective of whether
or not the Administrative Agent or such Creditor shall have made any demand hereunder and although said obligations, liabilities, deposits or claims, or any of them, shall be contingent or unmatured. Each Creditor agrees to promptly notify the
relevant Guarantor after any such set off and application, provided, however, that the failure to give such notice shall not affect the validity of such set off and application. 

  

	20.	 Notices. Except as otherwise expressly provided herein, all notices and other communications provided for hereunder shall be in writing (including
telegraphic, telex, facsimile transmission or cable communication) and mailed, telegraphed, telexed, transmitted, cabled or delivered, (i) if to any Guarantor, at 



  

 10 









	 	 
the address specified for it in Annex II to the Credit Agreement (or if no such address is specified, to it c/o the Company), with a courtesy copy to the
Company at its address specified in or pursuant to the Credit Agreement, (ii) if to the Administrative Agent, to it at its Notice Office, (iii) if to any Lender, at its address specified in or pursuant to the Credit Agreement, and (iv) if to any
Designated Hedge Creditor, at such address as such Designated Hedge Creditor shall have specified in writing to each Guarantor and the Administrative Agent; or in any case at such other address as any of the persons listed above may hereafter notify
the others in writing. All such notices and communications shall be mailed, telegraphed, telexed, telecopied, or cabled or sent by overnight courier, and shall be effective when received. 


  

	21.	Reinstatement. If claim is ever made upon the Administrative Agent or any other Creditor for rescission, repayment, recovery or restoration of any amount or amounts received
by the Administrative Agent or any other Creditor in payment or on account of any of the Guaranteed Obligations and any of the aforesaid payees repays all or part of said amount by reason of (x) any judgment, decree or order of any court or
administrative body having jurisdiction over such payee or any of its property, or (y) any settlement or compromise of any such claim effected by such payee with any such claimant (including the Borrower), then and in such event (i)
any such judgment, decree, order, settlement or compromise shall be binding upon each Guarantor, notwithstanding any revocation hereof or other instrument evidencing any liability of the Borrower, (ii) each Guarantor shall be and remain liable to
the aforesaid payees hereunder for the amount so repaid or otherwise recovered or restored to the same extent as if such amount had never originally been received by any such payee, and (iii) this Guaranty shall continue to be effective or be
reinstated, as the case may be, all as if such repayment or other recovery had not occurred. 

  

	22.	Governing Law; Venue. (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE ADMINISTRATIVE AGENT, THE OTHER CREDITORS AND OF THE UNDERSIGNED HEREUNDER SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE COMMONWEALTH OF PENNSYLVANIA, NOTWITHSTANDING ITS CONFLICTS OF LAWS RULES. Any legal action or proceeding with respect to this Guaranty may be brought in the Courts of the Commonwealth of
Pennsylvania, or of the United States of America for the Western District of Pennsylvania, and, by execution and delivery of this Guaranty, each Guarantor hereby irrevocably accepts for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts. Each Guarantor hereby irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered
mail, return receipt requested, to such Guarantor at its address provided herein, such service to become effective 30 days after such mailing, or such earlier time as may be provided by applicable law. Nothing herein shall affect the right of the
Administrative Agent or any of the other Creditors to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against each Guarantor in any other jurisdiction. 

  

	 	(b)	Each Guarantor hereby irrevocably waives any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in
connection with this Guaranty or any other Credit Document or Guaranteed Document brought in the courts referred to in section 22(a) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that such action or
proceeding brought in any such court has been brought in an inconvenient forum. 

  

	23.	Sale of Capital Stock of a Guarantor. In the event that all of the capital stock of one or more Guarantors is sold or otherwise disposed of or liquidated in compliance
with the requirements of section 10.2 of the Credit Agreement (or such sale or other disposition has been approved in writing by the Required Lenders (or all Lenders, or all of the Lenders (other than any Defaulting Lender), as applicable, if
required by section 13.12 of the Credit Agreement)) and the proceeds of such sale, disposition or liquidation are applied, to the extent applicable, in accordance with the provisions of the Credit Agreement, such Guarantor shall be released from
this Guaranty and this Guaranty shall, as to each such Guarantor or Guarantors, terminate, and have no further force or effect (it being understood and agreed that the sale of one or more persons that own, directly or indirectly, all of the capital
stock or other equity interests of any Guarantor shall be deemed to be a sale of such Guarantor for the purposes of this section 23). 

  

	24.	 Contribution Among Guarantors. Each Guarantor, in addition to the subrogation rights it shall have against the Borrower under applicable law as a
result of any payment it makes hereunder, shall also have 



  

 11 









	 	 
a right of contribution against all other Guarantors in respect of any such payment pro rata among same based on their respective net fair
value as enterprises, provided any such right of contribution shall be subject and subordinate to the prior payment in full of the Guaranteed Obligations (and such Guarantor’s obligations in respect thereof).



  

	25.	Full Recourse Obligations; Effect of Fraudulent Transfer Laws, etc. It is the desire and intent of each Guarantor, the Administrative Agent and the other Creditors that this
Guaranty shall be enforced as a full recourse obligation of each Guarantor to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. If and to the extent that the obligations of
any Guarantor under this Guaranty would, in the absence of this sentence, be adjudicated to be invalid or unenforceable because of any applicable state or federal law relating to fraudulent conveyances or transfers, then the amount of such
Guarantor’s liability hereunder in respect of the Guaranteed Obligations shall be deemed to be reduced ab initio to that maximum amount which would be permitted without causing such Guarantor’s obligations
hereunder to be so invalidated. 

  

	26.	Payments Free and Clear of Setoffs, Counterclaims and Taxes, etc. (a) All payments made by any Guarantor hereunder will be made without setoff, counterclaim or other defense
and, except as provided for in section 26(b), all such payments will be made free and clear of, and without deduction or withholding for, any present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now
or hereafter imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein with respect to such payments (but excluding, except as provided in the second succeeding sentence, any tax, imposed on or measured by
the net income or net profits of a Creditor pursuant to the laws of the jurisdiction under which such Creditor is organized or the jurisdiction in which the principal office or Applicable Lending Office of such Creditor is located or any subdivision
thereof or therein) and all interest, penalties or similar liabilities with respect to such non excluded taxes, levies imposts, duties, fees, assessments or other charges (all such nonexcluded taxes, levies, imposts, duties, fees, assessments or
other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, the applicable Guarantor agrees to pay the full amount of such Taxes and such additional amounts as may be
necessary so that every payment by it of all amounts due hereunder, after withholding or deduction for or on account of any Taxes will not be less than the amount provided for herein, If any amounts are payable in respect of Taxes pursuant to the
preceding sentence, the applicable Guarantor agrees to reimburse each Creditor, upon the written request of such Creditor for taxes imposed on or measured by the net income or profits of such Creditor pursuant to the laws of the jurisdiction in
which such Creditor is organized or in which the principal office or Applicable Lending Office of such Creditor is located or under the laws of any political subdivision or taxing authority of any such jurisdiction in which the principal office or
Applicable Lending Office of such Creditor is located and for any withholding of income or similar taxes imposed by the United States of America as such Creditor shall determine are payable by, or withheld from, such Creditor in respect of such
amounts so paid to or on behalf of such Creditor pursuant to the preceding sentence, which request shall be accompanied by a statement from such Creditor setting forth, in reasonable detail, the computations used in determining such amounts. The
applicable Guarantor will furnish to the Administrative Agent within 45 days after the date the payment of any Taxes, or any withholding or deduction on account thereof, is due pursuant to applicable law certified copies of tax receipts, or other
evidence satisfactory to the applicable Creditor, evidencing such payment by the applicable Creditor. Each applicable Guarantor will indemnify and hold harmless the Administrative Agent and each Creditor, and reimburse the Administrative Agent or
such Creditor upon its written request, for the amount of any Taxes so levied or imposed and paid or withheld by such Creditor. 

  

	 	(b)	Notwithstanding anything to the contrary contained in section 26(a), (i) any applicable Guarantor shall be entitled, to the extent it is required to do so by law, to deduct or
withhold income or other similar taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from any amounts payable hereunder for the account of any Creditor which is not a United States person (as such
term is defined in section 7701(a)(30) of the Code) for United States federal income tax purposes and which has not provided to the Borrower such forms that establish a complete exemption from such deduction or withholding; and (ii) any applicable
Guarantor shall not be obligated pursuant to section 26(a) hereof to gross-up payments to be made to a Creditor in respect of income or similar taxes imposed by the United States or any additional amounts with respect thereto if such Creditor has
not provided to the Borrower such forms. 

  

 12 









	27.	Judgment Currency. (a) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in any currency (the “Original
Currency”) into another currency (the “Other Currency”) each Guarantor, the Administrative Agent and the other Creditors, by their acceptance of the benefits hereof, 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 Administrative Agent could purchase the Original Currency with the Other Currency at the Payment Office on the second Business
Day preceding that on which final judgment is given. 

  

	 	(b)	The obligation of a Guarantor in respect of any sum due in the Original Currency from it to the Administrative Agent or any other Creditor hereunder shall, notwithstanding any
judgment in any Other Currency, be discharged only to the extent that on the Business Day following receipt by such Creditor or the Administrative Agent (as the case may be) of any sum adjudged to be so due in such Other Currency such Creditor or
the Administrative Agent (as the case may be) may in accordance with normal banking procedures purchase U.S. Dollars with such Other Currency; if the amount of the Original Currency so purchased is less than the sum originally due to such Creditor
or the Administrative Agent (as the case may be) in the Original Currency, such Guarantor agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Creditor or the Administrative Agent (as the case may be) against
such loss, and if the amount of the Original Currency so purchased exceeds the sum originally due to the Administrative Agent or any other Creditor (as the case may be) in the Original Currency, the Administrative Agent or such other Creditor (as
the case may be) agrees to remit to such Guarantor such excess. 

  

	28.	Termination. After the termination of the Total Commitment and all Designated Hedge Documents, when no Note nor Letter of Credit is outstanding and when all Loans and
other Guaranteed Obligations (other than unasserted indemnity obligations) have been indefeasibly paid in full, this Guaranty will terminate and the Administrative Agent, at the request and expense of the Borrower and/or any of the Guarantors, will
execute and deliver to the Guarantors a proper instrument or instruments acknowledging the satisfaction and termination of this Guaranty. 

  

	29.	Enforcement Only by Administrative Agent. The Creditors agree that this Guaranty may be enforced only by the action of the Administrative Agent, acting upon the
instructions of the Required Lenders, and that no Creditor shall have any right individually to seek to enforce or to enforce this Guaranty, it being understood and agreed that such rights and remedies may be exercised by the Administrative Agent,
for the benefit of the Creditors, upon the terms of this Guaranty. The Administrative Agent and the other Creditors further agree that this Guaranty may not be enforced against any director, officer or employee of any Guarantor, as such.


  

 13 









	30.	General Limitation on Claims by Guarantors. No claim may be made by any Guarantor against the Administrative Agent or any other Creditor, or the Affiliates, directors,
officers, employees, attorneys or agents of any of them, for any damages other than actual compensatory damages in respect of any claim for breach of contract or any other theory of liability arising out of or related to the transactions
contemplated by this Guaranty or any of the other Guaranteed Documents, or any act, omission or event occurring in connection therewith; and each Guarantor hereby, to the fullest extent permitted under applicable law, waives, releases and agrees not
to sue or counterclaim upon any such claim for any special, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor. 

  

	31.	Attorneys, Accountants, etc. of Creditors Have No Duty to Guarantors. All attorneys, accountants, appraisers, consultants and other professional persons (including the firms
or other entities on behalf of which any such person may act) retained by the Administrative Agent or any other Creditor with respect to the transactions contemplated by the Guaranteed Documents shall have the right to act exclusively in the
interest of the Administrative Agent or such other Creditor, as the case may be, and shall have no duty of disclosure, duty of loyalty, duty of care, or other duty or obligation of any type or nature whatsoever to any Guarantor, to any of its
Affiliates, or to any other person, with respect to any matters within the scope of such representation or related to their activities in connection with such representation. Each Guarantor agrees, on behalf of itself and its Affiliates, not to
assert any claim or counterclaim against any such persons with regard to such matters, all such claims and counterclaims, now existing or hereafter arising, whether known or unknown, foreseen or unforeseeable, being hereby waived, released and
forever discharged. 

  

	32.	Creditors Not Fiduciary to Guarantors, etc. The relationship among any Guarantor and its Affiliates, on the one hand, and the Administrative Agent and the other
Creditors, on the other hand, is solely that of debtor and creditor, and the Administrative Agent and the other Creditors have no fiduciary or other special relationship with any Guarantor or any of its Affiliates, and no term or provision of any
Guaranteed Document, no course of dealing, no written or oral communication, or other action, shall be construed so as to deem such relationship to be other than that of debtor and creditor. 

  

	33.	Counterparts. This Guaranty may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed
and delivered shall be an original, but all of which shall together constitute one and the same instrument. A set of counterparts executed by all the parties hereto shall be lodged with the Company and the Administrative Agent.


  

 14 









	34.	Waiver of Jury Trial. EACH GUARANTOR, THE ADMINISTRATIVE AGENT AND EACH OTHER CREDITOR (BY THEIR ACCEPTANCE OF THE BENEFITS HEREOF) HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL
BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY OR ANY OF THE OTHER CREDIT DOCUMENTS (INCLUDING, WITHOUT LIMITATION, ANY AMENDMENTS, WAIVERS OR OTHER MODIFICATIONS RELATING TO ANY OF THE FOREGOING), OR
THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH GUARANTOR, THE ADMINISTRATIVE AGENT AND EACH OTHER CREDITOR (BY THEIR ACCEPTANCE OF THE BENEFITS HEREOF) HEREBY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PERSONS PARTY HERETO OR BENEFITTED HEREBY HAVE BEEN INDUCED TO ENTER
INTO OR ACCEPT THE BENEFITS OF THIS GUARANTY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS PARAGRAPH.

	 $32,000,000.00
 Pittsburgh, Pennsylvania
	 	 February 18, 2004


  
 FOR VALUE
RECEIVED, the undersigned CALGON CARBON CORPORATION, a Delaware corporation (herein, together with its successors and assigns, the “Borrower”), hereby promises to pay to the order of NATIONAL CITY BANK OF
PENNSYLVANIA (the “Lender”), in lawful money of the United States of America, provided that General Revolving Loans denominated in an Alternative Currency shall be payable in such Alternative Currency, in immediately
available funds, at the Payment Office (such term and certain other terms used herein without definition shall have the meanings ascribed thereto in the Credit Agreement referred to below) of National City Bank of Pennsylvania (the
“Administrative Agent”), on the Maturity Date, the principal sum of THIRTY TWO MILLION DOLLARS AND NO CENTS ($32,000,000.00) or, if less, the then unpaid principal amount of all General Revolving Loans made by the
Lender to the Borrower pursuant to the Credit Agreement. 
  
 The
Borrower promises also to pay interest on the unpaid principal amount of each General Revolving Loan made by the Lender to the Borrower in like money at said office from the date hereof until paid at the rates and at the times provided in section
2.8 of the Agreement. 
  
 This Note is one of the General
Revolving Notes referred to in the Credit Agreement, dated as of February 18, 2004, among the Borrower, the financial institutions from time to time party thereto (including the Lender), and National City Bank of Pennsylvania, as Administrative
Agent (as from time to time in effect, the “Credit Agreement”), and is entitled to the benefits thereof and of the other Credit Documents (as defined in the Credit Agreement). As provided in the Credit Agreement, this Note is
subject to mandatory prepayment prior to the Maturity Date, in whole or in part. 
  
 In case an Event of Default shall occur and be continuing, the principal of and accrued interest on this Note may be declared to be due and payable in the manner and with the effect provided in the Credit Agreement.

  
 The Borrower hereby waives presentment, demand, protest or
notice of any kind in connection with this Note. No failure to exercise, or delay in exercising, any rights hereunder on the part of the holder hereof shall operate as a waiver of any such rights.
