the event the Merger has not been consummated on or before January 2, 2003, the Lender agrees, no later than five (5) business days after receipt of a written request therefor from the Borrower, to make, or to arrange for one or more of its affiliates to make, additional loans from time to time and as requested from and after January 2, 2003, up to the Maturity Date (as defined herein) (such additional loans, the “Additional Loans”) in an amount or amounts not to exceed $1,000,000 in the aggregate; provided, however, that if the Merger Agreement is terminated other than pursuant to Section 8.1(b), 8.1(c) or 8.1(d)(iii) thereof, then no Additional Loan need be made on or after the date of such termination, and provided further, that if the Merger Agreement is terminated pursuant to Section 8.1(b), 8.1(c) or 8.1(d)(iii) thereof, no Additional Loan need be made on or after such date of termination if immediately after such Additional Loan were made the aggregate outstanding amount of the Additional Loans would exceed $750,000. Any affiliate that makes an Additional Loan to the Borrower pursuant to the foregoing or an Initial Loan, or any portion thereof, pursuant to Section 1.1(a) hereof shall be referred to herein as an “Additional Lender”. Notwithstanding anything herein to the contrary, the Lender or any Additional Lender may make, but shall not be required to make, any requested Additional Loan if after such Additional Loan the total of the Borrower’s cash, cash equivalents and short-term investments would then exceed its working capital needs, as set forth in the Borrower’s 2003 Budget, which was delivered by the Borrower to the Lender prior to the execution of the Loan Agreement, dated as of September 6, 2002, by and among the Borrower and the Lender, for at least six (6) months from the date of the request. The principal amount of the Initial Loans and any Additional Loans (the “Aggregate Principal Amount”) together with all accrued interest thereon and expenses incurred by the Lender or any Additional Lender in connection therewith (the “Loans”) shall be due and payable in full on the Maturity Date.

(c) Notes. All amounts owed by the Borrower with respect to the Loans shall be evidenced by promissory notes in the form attached hereto as Exhibit A dated the date of each loan (each a “Note”, and collectively the “Notes”).

(d) Interest. Each Note shall bear interest, prior to the occurrence of an Event of Default (as defined in Article IV), at a rate per annum equal to the London InterBank Offered Rate (“LIBOR”) for one-year loans as published in the Wall Street Journal on the date of each Note, plus four and one-half percent (4.5%). From and after the occurrence of an Event of Default, the unpaid

Aggregate Principal Amount and, to the extent permitted by law, overdue interest, shall bear interest at the stated rate of interest plus an additional two percent (2%) per annum. Interest shall be calculated on the basis of actual days elapsed and on a 360 day year and shall be due and payable on the last business day of each calendar quarter. All unpaid accrued interest on the Notes shall be due and payable on the Maturity Date.

(e) Prepayment. The Borrower may at any time pay the full amount of the Notes without the payment of any premium or fee.

Section 1.2. Use of Proceeds. The entire proceeds of each Loan shall be converted into cash, cash equivalents or short-term investments or used by the Borrower for general working capital purposes in accordance with the Borrower’s 2003 Budget.

Section 1.3. Conditions Precedent to the Loans.

(d) Delivery of Documents to Lender. With respect to each Additional Loan, the Borrower shall have delivered to the Lender or Additional Lender, as applicable, a written request for such Additional Loan, including a certification from the Chief Executive Officer of the Borrower that after such Additional Loan the total of the Borrower’s cash, cash equivalents and short-term investments would not then exceed its working capital needs, as set forth in the Borrower’s 2003 Budget, for the six (6) months immediately following the date of the request.

Section 1.4. Availability of Funds. If the applicable conditions set forth above in

Section 1.3 have been satisfied prior to the Maturity Date, the Lender shall make, or arrange for one or more of its affiliates to make (i) the Initial Loans on the dates specified in Section 1.1(a) hereof; and (ii) any requested Additional Loan on or before five (5) business days after the request therefor has been made.
