All principal and unpaid accrued interest under the revolver credit facility shall be due and payable on the maturity date of the revolver. For that portion of the revolver loan that consists of Eurodollar loans, the revolver shall bear interest at LIBOR plus a margin rate of 1.75% per annum for the first six months and thereafter between 1.5% and 2.0%, depending on the Companys availability calculation (as defined in the Loan Agreement) and, for that portion of the revolver that consists of base rate loans, the revolver shall bear interest at the base rate then in effect plus a margin rate of 0.75% per annum for the first six months and thereafter between 0.50% and 1.0%, depending on the availability calculation. As of the closing, the Company elected all borrowings under the Loan Agreement to accrue interest at LIBOR which, as of that date, was 0.99500%. As such, the initial rate of interest for the revolver is 2.745% per annum and the initial rate of interest for the term loan is 2.995% per annum. The Loan Agreement provides for payment of an unused line fee of between 0.25% and 0.50%, depending on the amount by which the revolving credit loan commitment exceeds the amount of the revolving credit loans outstanding (including letters of credit), which shall be payable monthly in arrears on the average daily unused portion of the revolver.
