Commencing as of the date hereof and continuing until repayment in full of all sums due hereunder, the unpaid Principal Sum shall bear interest at the variable rate of interest, per annum, equal to the Prime Rate (as defined below) plus one half of one percent (.50%) per annum, provided, however, if Borrowers have net income of $1.00 or more in any fiscal quarter then the rate of interest applicable to this Note shall commencing as of the first day of the following quarter be reduced to the Prime Rate.  The rate of interest charged under this Note shall change immediately and contemporaneously with any change in the Prime Rate.  All interest payable under the terms of this Note shall be calculated on the basis of a 360-day year and the actual number of days elapsed.  As used herein, the “Prime Rate” shall mean Bank’s most recently announced “prime rate,” even if it is not Bank’s lowest rate.

The unpaid Principal Sum, together with interest thereon at the rate or rates provided above, shall be payable as follows:

(a)            Interest only on the unpaid principal amount shall be due and payable monthly in arrears, commencing April 5, 2005, and continuing on the fifth (5th) day of each calendar month thereafter to maturity; and

(b)            Unless sooner paid, the unpaid Principal Sum, together with interest accrued and unpaid thereon, shall be due and payable in full on the Revolving Maturity Date.

The fact that the balance hereunder may be reduced to zero from time to time pursuant to the Loan Agreement will not affect the continuing validity of this Note or the Loan Agreement, and the balance may be increased to the Principal Sum after any such reduction to zero.

Each Borrower hereby represents, agrees and covenants that the Obligations evidenced hereby are deemed “Designated Senior Indebtedness” for purposes of that certain Indenture between the Company and State Street Bank and Trust Company dated October 20, 2000, as the same may be amended, restated or otherwise modified from time to time.
