Subject to the Subordination Agreement, the principal of and interest on this Note shall become payable in full on the later of January 1, 2004 or one business day after all Obligations (as defined in the Subordination Agreement) shall have been indefeasibly paid in full.

A.    A failure to pay the principal of or interest on this Note when due, and the continuance of such default 30 days after written notice thereof shall have been provided by the Lender to the Obligor;

B.    A material attachment, garnishment, levy or lien shall be made, issued or filed against any of the assets of the Obligor, and such action shall not be discharged within sixty days; or

D.    A change of control of the Obligor occurs of a nature that would be required to be reported in the Obligor’s proxy statement under the Securities Exchange Act of 1934, as amended;

then in any such event, but subject to the Subordination Agreement, the holder of this Note may at any time thereafter (unless all such Events of Default shall theretofore have been fully cured to the satisfaction of such holder, and all costs and expenses, including without limitation attorneys’ fees and expenses, incurred by or on behalf of such holder shall have been paid by the Obligor), by notice to the Obligor, declare the entire outstanding principal of this Note to be due and payable immediately, and upon such declaration such principal, and all accrued but unpaid interest, shall become and be immediately due and payable, without further notice.

Subject to the Subordination Agreement, this Note may at the option of the Obligor at any time or from time to time be prepaid, in whole or in part, without penalty or premium.

The principal of and interest on this Note is subject to automatic conversion into shares of the Common Stock of the Obligor, in the event and on the terms more fully provided in Section 4 of the Subordination Agreement.

Should the indebtedness represented by this Note or any part thereof be collected in any proceeding or placed in the hands of attorneys for collection, the Obligor agrees to pay, in addition to the principal and interest due and payable hereon, all costs of collecting this Note, including reasonable attorneys’ fees and expenses.

The Obligor expressly waives presentment, demand, protest or any other notice whatsoever.
