2. Amendments to Credit Agreement.

“and (b) in respect of the Term B Facility, 1.25% per annum for Base Rate Loans and 2.25% per annum for Eurodollar Rate Loans.

““Base Rate” means for any day a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 1/2 of 1%, (b) the rate of interest in effect for such day as publicly announced from time to time by Bank of America as its “prime rate”, and (c) the Eurodollar Rate plus 1.00%. The “prime rate” is a rate set by Bank of America based upon various factors including Bank of America’s costs and desired return, general economic conditions and other factors, and is used as a reference point for pricing some loans, which may be priced at, above, or below such announced rate. Any change in such prime rate announced by Bank of America shall take effect at the opening of business on the day specified in the public announcement of such change.”

“when used in connection with the Revolving Facility, the Term A Facility or the Term B Facility, if the Eurodollar Rate shall be less than zero, such rate shall be deemed zero for purposes of this Agreement;”

“Notwithstanding anything to the contrary contained herein, any prepayment of the Term B Facility made after the Second Amendment Effective Date but on or prior to the six (6) month anniversary of the Second Amendment Effective Date

“(c) Repricing Fee. If a Repricing Event is consummated after the Second Amendment Effective Date and on or prior to the six (6) month anniversary of the Second Amendment Effective Date, the Borrower agrees to pay to the Administrative Agent, for the ratable account of (i) each Term B Lender with Term B Loans that are repaid and (ii) each Term B Lender that withholds its consent to such Repricing Event and is replaced or terminated as a Term B Lender under Section 11.13, a fee in an amount equal to 1.00% of (x) in the case of a Repricing Event described in clause (i) of the definition thereof, the aggregate principal amount of all Term B Loans of such Term B Lender that are prepaid in connection with such Repricing Event and (y) in the case of a Repricing Event described in clause (ii) of the definition thereof, the aggregate principal amount of all Term B Loans of such Term B Lender that are so assigned or terminated and repaid under Section 11.13. Such fees shall be earned, due and payable upon the date of the effectiveness of such Repricing Event.”

“(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and L/C Advances of the applicable Class(es), accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents with respect to such Class(es) (including any amounts under Section 3.05 and, in the case of a Repricing Event described in clause (ii) of the definition thereof after the Second Amendment Effective Date and on or prior to the six (6) month anniversary of the Second Amendment Effective Date, the fee described in Section 2.08(c)) from (x) in the case of an assignment, the assignee (to the extent of such outstanding principal and accrued interest and fees (other than fees payable due to the occurrence of a Repricing Event)) or the Borrower (in the case of all other amounts (including fees payable due to the occurrence of a Repricing Event)) and (y) in the case of a termination and repayment, the Borrower;”
