(a)   The Borrower shall pay interest on each Base Rate Loan at the Base Rate in effect from time to time and on each Eurodollar Loan at the Adjusted LIBO Rate for the applicable Interest Period in effect for such Loan, plus , in each case, the Applicable Margin in effect from time to time.

(b)   While an Event of Default exists or after acceleration, at the option of the Required Lenders, the Borrower shall pay interest (" Default Interest ") with respect to all Eurodollar Loans at the rate otherwise applicable for the then-current Interest Period plus an additional 2% per annum until the last day of such Interest Period, and thereafter, and with respect to all Base Rate Loans and all other Obligations hereunder (other than Loans), at an all-in rate in effect for Base Rate Loans, plus an additional 2% per annum.

(c)   Interest on the principal amount of all Loans shall accrue from and including the date such Loans are made to but excluding the date of any repayment thereof. Interest on all outstanding Base Rate Loans shall be payable quarterly in arrears on the last day of each March, June, September and December and on the Commitment Termination Date. Interest on all outstanding Eurodollar Loans shall be payable on the last day of each Interest Period applicable thereto, and, in the case of any Eurodollar Loans having an Interest Period in excess of three months or 90 days, respectively, on each day which occurs every three months or 90 days, as the case may be, after the initial date of such Interest Period, and on the Commitment Termination Date. Interest on any Loan which is converted into a Loan of another Type or which is repaid or prepaid shall be payable on the date of such conversion or on the date of any such repayment or prepayment (on the amount repaid or prepaid) thereof. All Default Interest shall be payable on demand.

(d)   The Administrative Agent shall determine each interest rate applicable to the Loans hereunder and shall promptly notify the Borrower and the Lenders of such rate in writing (or by telephone, promptly confirmed in writing). Any such determination shall be conclusive and binding for all purposes, absent manifest error.

Section 2.12.   Fees .

(a)   The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon by the Borrower and the Administrative Agent.  

(b)   The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Applicable Percentage per annum (determined daily in accordance with Schedule I ) on the daily amount of the unused Commitment of such Lender during the Availability Period. For purposes of computing commitment fees with respect to the Commitments, the Commitment of each Lender shall be deemed used to the extent of the outstanding Loans of such Lender.

(c)    On the Closing Date, the Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon in writing by the Borrower and the Administrative Agent.

24

(d)   Accrued fees (other than the fees referenced in paragraphs (c) and (d)) shall be payable quarterly in arrears on the last day of each March, June, September and December, commencing on September 30, 2006 and on the Commitment Termination Date (and if later, the date the Loans shall be repaid in their entirety); provided   further , that any such fees accruing after the Commitment Termination Date shall be payable on demand.

Section 2.13.   Computation of Interest and Fees .

Interest hereunder based on the Administrative Agent’s prime lending rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first day but excluding the last day). All other interest and all fees shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed (including the first day but excluding the last day). Each determination by the Administrative Agent of an interest amount or fee hereunder shall be made in good faith and, except for manifest error, shall be final, conclusive and binding for all purposes.

Section 2.14.   Inability to Determine Interest Rates . If prior to the commencement of any Interest Period for any Eurodollar Borrowing,

(i)   the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower ) that, by reason of circumstances affecting the relevant interbank market, adequate means do not exist for ascertaining LIBOR for such Interest Period, or

(ii)   the Administrative Agent shall have received notice from the Required Lenders that the Adjusted LIBO Rate does not adequately and fairly reflect the cost to such Lenders (or Lender, as the case may be) of making, funding or maintaining their (or its, as the case may be) Eurodollar Loans for such Interest Period,

the Administrative Agent shall give written notice (or telephonic notice, promptly confirmed in writing) to the Borrower and to the Lenders as soon as practicable thereafter. In the case of Eurodollar Loans, until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) the obligations of the Lenders to make Eurodollar Loans or to continue or convert outstanding Loans as or into Eurodollar Loans shall be suspended and (ii) all such affected Loans shall be converted into Base Rate Loans on the last day of the then current Interest Period applicable thereto unless the Borrower prepays such Loans in accordance with this Agreement. Unless the Borrower notifies the Administrative Agent at least one Business Day before the date of any Eurodollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, then such Borrowing shall be made as a Base Rate Borrowing .

Section 2.15.   Illegality . If any Change in Law shall make it unlawful or impossible for any Lender to make, maintain or fund any Eurodollar Loan and such Lender shall so notify the Administrative Agent, the Administrative Agent shall promptly give notice thereof to the Borrower and the other Lenders, whereupon until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Eurodollar Loans, or to continue or convert outstanding Loans as or into Eurodollar Loans, shall be suspended. In the case of the making of a Eurodollar Borrowing, such Lender’s Loan shall be made as a Base Rate Loan as part of the same Borrowing for the same Interest Period and if the affected Eurodollar Loan is then outstanding, such Loan shall be converted to a Base Rate Loan either (i) on the last day of the then current Interest Period applicable to such Eurodollar Loan if such Lender may lawfully continue to maintain such Loan to such date or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain such Eurodollar Loan to such date. Notwithstanding the foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different Applicable Lending Office if such designation would avoid the need for giving such notice and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion.

Section 2.16.   Increased Costs .

(a)   If any Change in Law shall:

(i)   impose, modify or deem applicable any reserve, special deposit or similar requirement that is not otherwise included in the determination of the Adjusted LIBO Rate hereunder against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or  

(ii)   impose on any Lender or the eurodollar interbank market any other condition affecting this Agreement or any Eurodollar Loans made by such Lender;

and the result of either of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining a Eurodolla
