($1,000,000), with interest thereon as provided herein.

               1. Letter Agreement. This 9% Senior Promissory Note (this "Note")

                      (a) All principal and accrued and unpaid interest on this
Note shall be made in lawful money of the United States of America and in
immediately available funds to the Holder's account that the Holder shall
designate to the Company, on the earlier of (a) an Event of Default (as defined
in Section 6 below) or (b) April 15, 2002 (the "Maturity Date").

                      (b) The Company may not prepay this Note.

Business Day, on the next succeeding Business Day to occur after such date (each
date upon which interest shall be so payable, an "Interest Payment Date"),
beginning on March 31, 2002. Interest on this Note shall accrue from the date of
issuance until repayment of the principal and payment of all accrued interest in

interest on this Note as provided in the preceding sentence and shall not have
been paid in full on or before the next Interest Payment Date to occur after the
Interest Payment Date on which the overdue interest became due and payable shall
itself be deemed to be overdue interest on this Note to which the preceding
sentence shall apply. Notwithstanding anything herein to the contrary, the
interest payable by the Company with respect to this Note shall not exceed the
maximum amount permitted by applicable law.

               4. Rank. This Note shall be senior to all indebtedness of the
Company.

               5. Covenants. The Company covenants to the Holder that

have been paid in full, the Company shall: (i) punctually pay the interest and

the consent of the Holder other than purchase money security interests, and
capital and operating leases.

               6. Events of Default. Notwithstanding anything to the contrary
provided herein, the occurrence of any one or more of the following shall be an
"Event of Default" hereunder and, upon the occurrence of an Event of Default,
all principal and interest due hereunder shall be immediately due and payable:

                      (a) if default by the Company shall be made in the payment
when due of principal or interest under this Note, and such default shall be
continuing;

observance or performance of any other covenant, condition or agreement on the
part of the Company to be observed or performed pursuant to the terms hereof, or
to the terms of the Letter Agreement, and such default shall continue for five

or in any certificate or other document delivered pursuant thereto, shall have
been incorrect in any material respect when made, unless the same is capable of
being cured or corrected and is promptly cured or corrected (but in any event
not later than three days) and prior to being cured or corrected does not have a
material adverse effect on the Condition of the Company;

                      (d) if the Company or its subsidiaries shall: (i) fail to

any applicable grace period; or (ii) fail to perform or observe, and such
failure shall continue after any applicable grace period, any term, covenant or
condition on its part to be performed or observed under any agreement or
instrument relating to any such indebtedness the aggregate outstanding principal
amount of which as to any or all of the Company or its subsidiaries is in excess
of $250,000, when required to be performed or observed, if the effect of such
failure to perform or observe is to accelerate, or to permit the acceleration

indebtedness; or (iii) permit any such indebtedness, the aggregate outstanding
principal amount of which is in excess of $250,000, to have been declared to be

as they become due, or shall consent to the appointment of a receiver or
receivers of all or any part of its property; or

                      (g) if any of the creditors of the Company or any of its
subsidiaries shall file an involuntary petition in bankruptcy against the
Company or any of its subsidiaries, or for reorganization of the Company or any
of its subsidiaries, and if such petition shall not be discharged or dismissed
within sixty (60) days after the date on which such petition was filed.
