Borrower acknowledges that at the time of entry of this Loan the actual principal amount owed is Two Million One Hundred Ninety Seven Thousand Eight Hundred Dollar and seventy three cents ($2,197,800.73) (including the $197,800.73 "Over-Advance"). The Base Loan Principal is payable in 24 level payments of $75,000.00 each, commencing on May 1, 2003 and continuing on the first day of each successive month until March 1, 2005. Any balance of principal and interest remaining shall be due and payable as a lumpsum payment on April 1, 2005. The rate of interest charged Borrower shall in no event be greater than that allowed by law. All payments received will be applied first to interest and other charges, if any, due Lender, and any remaining amount shall be applied to unpaid principal. The Over-Advance principal and the interest accruing thereon shall be payable as follows: 25% of the account receivable cash flow monitored and collected by Lender, over and above the Base Loan Payment of $75,000.00, shall be retained each month, commencing May 1, 2003, until said Over-Advance and all interest due thereon is fully paid. Any balance of principal and interest remaining on the Over-Advance, if any, shall be due and payable as a lumpsum payment on April 1, 2005. Anything to the contrary not withstanding, a maximum of $50,000.00 per month shall be applied to the Over-Advance; in the event monthly receipts are less than $200,000.00, no more than $25,000.00 shall be applied to the Over-Advance. Borrower has entered into a Loan and Security Agreement (the "Agreement") of even date herewith, pursuant to which this Promissory Note has been made and delivered to Lender and under which Lender has taken certain collateral as security for the repayment of this Note, including, without limitation, certain invoices and accounts receivable, furniture, fixtures, equipment, inventory (including work in progress and raw material), and intellectual property consisting of U.S. Patents, U.S. Copyrights and U.S. Trademarks. Any default by Borrower under the Agreement shall constitute a default under this Note. In the event Borrower defaults in the payment of any amount due hereunder when due; or Borrower defaults under any of the terms or provisions of the Agreement, then in such event, the entire principal balance then outstanding hereunder, plus accrued and unpaid interest and charges, if any, shall become immediately due and payable, at the office of Lender, without notice to Borrower, and may be collected forthwith. Lender's failure to exercise its rights under this paragraph shall not constitute a waiver thereof. It is further agreed that said accelerated principal balance plus the accrued and unpaid charges, if any, or so much thereof as may remain unpaid from time to time, shall earn interest at the rate which otherwise would have been in effect absent Lender's election to accelerate, and shall remain in effect until the accelerated balance is paid in full. Borrower further agrees to pay Lender all costs and expenses suffered or incurred in connection with the enforcement of Lender's rights under this Note and Agreement, including reasonable attorney fees actually incurred not to exceed fifteen percent (15%) of the unpaid principal amount and interest due. Lender's acceptance of partial or delinquent payments or the failure of Lender to exercise any right shall not waive any obligation of the Borrower or right of Lender or modify the Agreement or waive any other similar default. Whenever any notice, demand or request is required, permitted or given hereunder or under any related loan document, such notice, demand or request shall be hand delivered or sent by United States Mail, registered or certified, postage prepaid, to the addresses set forth below: As to Borrower: Mr. Brett Sweezy, Chief Financial Officer LIFESTREAM TECHNOLOGIES, INC. 510 Clearwater Loop, Suite 101 Post Falls, Idaho 83854 With a Copy to: Ford Elsaesser, Esq.
