         (c) Use of Proceeds. The Borrower shall use the proceeds from the Loan

         (d) Mandatory Prepayment. If Borrower (x) is terminated for Cause by

Reason, then within three (3) business days after the receipt by the Borrower of
any Net Proceeds, the Borrower shall apply such Net Proceeds to as follows:

                  (i) if the Current Value of the Pledged Stock and the Other
Stock is equal to or greater than the Minimum Collateral Value, the Net Proceeds
Payable shall be applied by the Borrower ratably to the prepayment of the Loans,
and the remainder of the Net Proceeds shall be retained by the Borrower;
provided, however, that if the Current Value of the Pledged Stock and the Other
Stock is less than the Minimum Collateral Value, the Borrower must make
prepayment pursuant to paragraph (ii) below.

                  (ii) if the Current Value of the Pledged Stock and the Other

<PAGE>   6

No course of dealing on the part of the holder of this Note nor any delay or

operate as a waiver of such right or otherwise prejudice such holder's rights,
powers and remedies. If the Borrower fails to comply with any provision of this
Note the Borrower shall pay to the holder, to the extent permitted by applicable
law, such further amounts as shall be sufficient to cover the costs and

from time to time, to the fullest extent permitted by law, to set off and apply
any and all amounts at any time held and all indebtedness of other amounts at
any time owing by the Borrower to or for the credit or the account of the
Company regardless of the currency in which any such deposit, amount or
indebtedness may be denominated, against any and all of the due and payable
obligations of the Borrower now or hereafter existing, irrespective of whether
or not the Company shall have made any demand. The Company will promptly notify
the Borrower after any such set-off and application, provided that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of the Company hereunder are in additional to other
rights and remedies (including, without limitation, other rights of set-off)
which the Company may have.

principal of, and interest accrued on, this Note then outstanding to be, and

No course of dealing on the part of the holder of this Note nor any delay or
failure on the part of the holder of this Note to exercise any right shall
operate as a waiver of such right or otherwise prejudice such holder's rights,
powers and remedies. If the Borrower fails to comply with any provision of this
Note the Borrower shall pay to the holder, to the extent permitted by applicable
law, such further amounts as shall be sufficient to cover the costs and
expenses, including but not limited to reasonable attorneys' fees, incurred by
such holder in collecting any sums due on this Note or in otherwise assessing,
analyzing or enforcing any rights or remedies that are or may be available to
it.

The Borrower further waives and agrees not to assert any rights or privileges it
may acquire under Section 9-112 of the New York Uniform Commercial Code. Subject
to the Amended and Restated Pledge Agreement, the Borrower shall not be liable
for the deficiency if the proceeds of any sale or other disposition of the
Collateral are insufficient to pay all amounts to which the holder of the Note
is entitled, and the fees of any attorneys employed by the holder of the Note to
collect such deficiency.

from time to time, to the fullest extent permitted by law, to set off and apply
any and all amounts at any time held and all indebtedness of other amounts at
any time owing by the Borrower to or for the credit or the account of the
Company regardless of the currency in which any such deposit, amount or
indebtedness may be denominated, against any and all of the due and payable
obligations of the Borrower now or hereafter existing, irrespective of whether
or not the Company shall have made any demand. The Company will promptly notify
the Borrower after any such set-off and application, provided that the failure
to give such notice shall not affect the validity of such set-off and
application. The rights of the Company hereunder are in additional to other
rights and remedies (including, without limitation, other rights of set-off)
which the Company may have.
