PROMISSORY NOTE - LINE OF CREDIT

Credit. To draw on this Credit Agreement, Borrower shall notify the Lender in writing of its intent to draw on this Credit Agreement. In such notice, Borrower must state an amount it wishes to withdraw and a date it desires to receive such funds. Upon receiving such notice, the Lender shall within 3 business days of the date requested, by check or wire transfer in U.S. Dollars, pay to the Borrower such amount requested.

Interest. Interest will be paid at a rate of Six Percent (6.00%) per annum (calculated on the basis of a 360-day year) (the “Rate”).

Interest Payment. Interest is to be paid in advance on the first (1st) day of each quarter of the year, (March 31^st, June 30^th, September 30^th, December 31^st), (each, an “Interest Payment Date”) and shall be paid in cash.

Payment at Maturity. The outstanding principal amount of this Line of Credit, together with all due and unpaid interest, shall be due and payable in cash on the date that is the earlier of (i) the third (3rd) anniversary of the date of this Credit Agreement or (ii) the next Business Day.

Prepayment. Prepayment of principal, together with accrued interest, may be made at any time without penalty.

Default. In the event that any amount of principal hereof, or (to the extent permitted by applicable law) any interest hereon or any other amount payable hereunder is not paid in full when due (whether as scheduled, on demand, by acceleration or otherwise), Borrower shall pay interest (after as well as before entry of judgment thereon to the extent permitted by law) on such unpaid amount to Lender, from the date such amount becomes due until the date such amount is paid in full, payable on demand of Lender at a rate per annum equal at all times to 12% per annum (the “Default Rate”). Additionally, and without limiting the foregoing, following the occurrence and during the continuance of any Event of Default (as defined below), at the option of Lender, the interest rate shall be the Default Rate. Such interest on overdue amounts shall be payable on demand. All computations of interest shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest is payable. Each determination by Lender of any applicable rate of interest, and of any change therein, in the absence of manifest error shall be conclusive and binding on the parties hereto.

Payment in general. Payment shall be made in lawful tender of the United States unconditionally in full without set-off, counterclaim or, to the extent permitted by applicable law, other defense, all of which rights of Borrower are hereby expressly waived by Borrower. All payments hereunder shall be made to Lender at Lender’s address set forth above (or to such other place as Lender shall designate in a written notice to Borrower), and, unless Borrower has obtained Lender’s written consent to another form of payment, such payment shall be made by wire transfer of immediately available funds by no later than 12:00 noon (Boston time) on the due date of the payment, in accordance with Lender’s payment instructions.
