FOR VALUE RECEIVED, the undersigned (whether one or more, “Borrower”) promises to pay to BANK OF AMERICA, N.A. (“Bank”), or order, the sum of Thirty-Seven Million Five Hundred Thousand Dollars ($37,500,000), or so much thereof as shall have been disbursed from time to time and remains unpaid, together with interest at the rate and payable in the manner hereinafter stated. Subject to compliance with the Loan and Security Agreement (defined below), Borrower may borrow, repay and reborrow from time to time under this Note. Principal and interest shall be payable at any banking office of Bank in the city or town indicated above, or such other place as the holder of this Note may designate.

Article I. Interest Rate.

Section 1.1. Rate of Accrual. Interest will accrue on the unpaid principal balance at the rate set forth in Section 1.2.1. until maturity of this Note, whether such maturity occurs by acceleration or on the Maturity Date; and, at Bank’s option, interest at the foregoing rate will accrue on any unpaid interest before such maturity. Interest will accrue on any unpaid balance owing under this Note, whether principal, interest, fees, premiums, charges or costs and expenses, after maturity at the rate set forth in Section 1.2.2. All accrual rates of interest under this Note will be contract rates of interest, whether a pre-default rate or a default rate, and references to contract rates in any loan documents executed and delivered by Borrower or others to Bank in connection with this Note shall be to such contract rates.

Section 1.2. Interest Rates.

1.2.1. Pre-Default Rate. Subject to the provisions of Section 1.2.2. below, interest payable on this Note per annum will accrue at a variable rate per annum equal to the LIBOR Market Index Rate plus 1.75%. “LIBOR Market Index Rate”, for any day, is the rate for 1 month U.S. dollar deposits as reported on Telerate Page 3750 as of 11:00 a.m., London time, on such day, or if such day is not a London business day, then the immediately preceding London business day (or if not so reported, then as determined by Bank from another recognized source or interbank quotation). The rate may be adjusted from time to time in Bank’s sole discretion for then applicable reserve requirements, deposit insurance assessment rates and other regulatory costs. Bank’s determination of such interest rate shall be conclusive, absent manifest error.

1.2.2 Default Rate. Upon the nonpayment of any payment of interest described herein, Bank, at its option and without accelerating this Note, may accrue interest on such unpaid interest at a rate per annum (“Default Rate”) equal to the lesser of the maximum contract rate of interest that may be charged to and collected from Borrower on the loan evidenced by this Note under applicable law or five percent (5.0%) plus the pre-default interest rate otherwise applicable hereunder, as set forth in Section 1.2.1. After maturity of this Note, whether by acceleration or otherwise, interest will accrue on the unpaid principal of this Note, any accrued but unpaid interest and all fees, premiums, charges and costs and expenses owing hereunder at the Default Rate until this Note is paid in full, whether this Note is paid in full pre-judgement or post-judgement.

1.2.3. Variable Rate; Calculation of Interest.

1.2.3.1 Variable Rate. This is a variable rate note. Any change in the rate of interest payable under this Note will equal the change in the variable rate index to which such rate is tied, but the rate at which interest accrues under this Note shall never exceed the maximum contract rate which may be charged to and collected from Borrower on the loan evidenced by this Note under applicable law. Bank shall have no obligation to notify Borrower of adjustments in the rate of interest payable under this Note. Adjustments to the rate of interest will be effective on the day of any change in the variable rate index, with the rate being adjusted to reflect the most recent change in the variable rate index.

1.2.3.2 Calculation of Interest. All interest payable under this Note shall be calculated monthly and will accrue daily on the basis of the actual number of days elapsed and a year of three hundred sixty (360) days. In computing the number of days during which interest accrues, the day on which funds are initially advanced shall be included regardless of the time of day such advance is made, and the day on which funds are repaid shall be included unless repayment is credited prior to close of business. Payments in federal funds, immediately available in the place designated for payment, received by Bank prior to 2:00 p.m. local time at said place of payment, shall be credited as if received prior to close of business on the day the funds are immediately available; while other payments, at the option of Bank, may not be credited until such payments are immediately available to Bank, in federal funds, in the place designated for payment, prior to 2:00 p.m. local time at said place of payment on a day on which Bank is open for business.

Article II. Payment Terms.

Section 2.1. Interest Payment Terms. Payments under this Note include an interest component and a principal component. The principal component is set forth in Section 2.2 below. The interest component shall be paid as follows: interest shall be payable monthly, in arrears, beginning January 1, 2006 and continuing on the same calendar day of each consecutive month thereafter until the Maturity Date, when all accrued but unpaid interest is due and payable in full.

Section 2.2. Principal Payment Terms; Maturity Date. As stated in Section 2.1 above, payments under this Note include an interest component and a principal component. The interest component is set forth in Section 2.1 above. The principal component shall be paid as follows: if not sooner paid, then principal shall be payable in one single payment on the Maturity Date (as defined in the Loan and Security Agreement), as the same may be extended from time to time in accordance with the terms of the Loan and Security Agreement.

Section 2.3. Prepayment. This Note may be prepaid in whole, or in part at any time without any prepayment premium.

Section 2.4. Application of Payments. All payments made on this Note shall be applied first to payment of all late fees, charges, premiums and costs and expenses due but unpaid under this Note, then to accrued but unpaid interest and finally to principal, in the inverse order of the payment dates therefor, unless Bank determines in its sole discretion to apply payments in a different order or applicable law requires a different application of payments. The partial prepayment of this Note, if permitted, shall not result in a payment holiday or any other deferral of any regularly scheduled payments under this Note, all of which shall be made as and when the same are scheduled to be paid.
