(Hereinafter referred to as “Bank”)

Borrower promises to pay to the order of Bank, in lawful money of the United States of America, at its office indicated above or wherever else Bank may specify, the sum of Seven Million Dollars ($7,000,000.00) or such sum as may be advanced and outstanding from time to time, with interest on the unpaid principal balance at the rate and on the terms provided in this Promissory Note (including all renewals, extensions or modifications hereof, this “Note”).

LOAN AGREEMENT. This Note is subject to the provisions of that certain Loan Agreement between Bank and Borrower of even date herewith, as same may be modified from time to time (the “Loan Agreement”).

USE OF PROCEEDS. Borrower shall use the proceeds of the loan evidenced by this Note to purchase equipment.

ADVANCES. Provided that the Borrower is not in default under the Loan Documents, Bank will make advances on the Loan to the Borrower upon the presentation of invoices from the manufacturer. The advance will be within three (3) days of the submission of the invoice to the Bank.

INTEREST RATE. Interest shall accrue on the unpaid principal balance of this Note during each Interest Period from the date hereof at a rate per annum equal to 1-month LIBOR plus a spread (the “Spread”) which Spread will be based on the Borrower’s performance under the grid (the “Grid”) set forth below (the “Interest Rate”):

- 1 -

Each adjustment in the Interest Rate will be made quarterly upon the submission of the quarterly financial information required by the Loan Agreement. Interest Rate adjustments will be made at the end of each Interest Period. “Interest Period” means each period commencing on and including the date an interest payment is due as provided in the Repayment Terms paragraph and ending on but excluding the date the next interest payment is due, with the first interest period commencing on the date of closing. Upon determination by Bank of the Interest Rate for any Interest Period, such Interest Rate shall remain in effect for the entire Interest Period until redetermined for the next successive Interest Period. “LIBOR” is the rate for U.S. dollar deposits with a maturity equal to the number of months specified above, as reported on Telerate page 3750 as of 11:00 a.m., London time, on the second London business day before the relevant Interest Period begins (or if not so reported, then as determined by Bank from another recognized source or interbank quotation).

INDEMNIFICATION. Borrower shall indemnify Bank against Bank’s loss or expense as a consequence of (a) Borrower’s failure to make any payment when due under this Note, (b) any payment, prepayment or conversion of any loan on a date other than the last day of the Interest Period, or (c) any failure to make a borrowing or conversion after giving notice thereof (“Indemnified Loss or Expense”). The amount of such Indemnified Loss or Expense shall be determined by Bank based upon the assumption that Bank funded 100% of that portion of the loan in the London interbank market.

DEFAULT RATE. In addition to all other rights contained in this Note, if a Default (as defined herein) occurs and as long as a Default continues, all outstanding Obligations shall bear interest at the Interest Rate plus 3% (“Default Rate”). The Default Rate shall also apply from acceleration until the Obligations or any judgment thereon is paid in full.

INTEREST AND FEE(S) COMPUTATION (ACTUAL/360). Interest and fees, if any, shall be computed on the basis of a 360-day year for the actual number of days in the applicable period (“Actual/360 Computation”). The Actual/360 Computation determines the annual effective yield by taking the stated (nominal) rate for a year’s period and then dividing said rate by 360 to determine the daily periodic rate to be applied for each day in the applicable period. Application of the Actual/360 Computation produces an annualized effective rate exceeding the nominal rate.

REPAYMENT TERMS. Borrower will make monthly payments of interest only beginning with the payment due on September 1, 2007 and on the same day of each and every month thereafter until March 1, 2008. Thereafter, Borrower will make monthly payments of principal in an amount equal to one-sixtieth (1/60^th) of the principal amount outstanding on the Loan as of March 1, 2008, plus interest at the rate set forth above. All remaining principal and interest shall be due and payable in full on March 1, 2013.

AUTOMATIC DEBIT OF CHECKING ACCOUNT FOR LOAN PAYMENT. Borrower authorizes Bank to debit demand deposit account number 2000012988228 or any other account with Bank (routing number 21200025) designated in writing by Borrower, beginning on September 1, 2007 for any payments due under this Note. Borrower further certifies that Borrower holds legitimate ownership of this account and preauthorizes this periodic debit as part of its right under said ownership.

APPLICATION OF PAYMENTS. Monies received by Bank from any source for application toward payment of the Obligations shall be applied to accrued interest and then to principal. If a Default occurs, monies may be applied to the Obligations in any manner or order deemed appropriate by Bank.

If any payment received by Bank under this Note or other Loan Documents is rescinded, avoided or for any reason returned by Bank because of any adverse claim or threatened action, the returned payment shall remain payable as an obligation of all persons liable under this Note or other Loan Documents as though such payment had not been made.

LATE CHARGE. If any payments are not timely made, Borrower shall also pay to Bank a late charge equal to 5% of each payment past due for 10 or more days.

Acceptance by Bank of any late payment without an accompanying late charge shall not be deemed a waiver of Bank’s right to collect such late charge or to collect a late charge for any subsequent late payment received.

ATTORNEYS’ FEES AND OTHER COLLECTION COSTS. Borrower shall pay all of Bank’s reasonable expenses incurred to enforce or collect any of the Obligations including, without limitation, reasonable arbitration, paralegals’, attorneys’ and experts’ fees and expenses, whether incurred without the commencement of a suit, in any trial, arbitration, or administrative proceeding, or in any appellate or bankruptcy proceeding.

USURY. If at any time the effective interest rate under this Note would, but for this paragraph, exceed the maximum lawful rate, the effective interest rate under this Note shall be the maximum lawful rate, and any amount received by Bank in excess of such rate shall be applied to principal and then to fees and expenses, or, if no such amounts are owing, returned to Borrower.
