the obligations of the Payee in the Agreement with respect to the conditions
and procedures for transfer of this Note.

            D. ENFORCEABILITY. Maker acknowledges that this Note and Maker's
obligations hereunder are and shall at all times continue to be absolute and
unconditional in all respects, and shall at all times be valid and
enforceable irrespective of any other agreements or circumstances of any
nature whatsoever which might otherwise constitute a defense to this Note and
the obligations of Maker evidenced hereby, unless otherwise expressly
evidenced in a writing duly executed by the holder hereof.

presentment, demand, protest and notice of any kind whatsoever. The
nonexercise by Payee of any of its rights hereunder in any particular
instance shall not constitute a waiver thereof in that or any subsequent
instance. The Payee, in addition to any other right available to it under
applicable law, shall have the right, at its option, to immediately set off
against this Note all monies owed by the Payee in any capacity to Maker,
whether or not due, upon the occurrence of any Event of Default, even though
such charge is made or entered on the books of Payee subsequent to those
events.

reasonably satisfactory to it of the loss, theft, destruction or mutilation
of this Note or any Note exchanged for it, and (i) in the case of loss, theft
or destruction, of indemnity satisfactory to it and (ii) in the case of
mutilation, of surrender for cancellation of such Note, and, in any case,
upon reimbursement to the Company of all reasonable expenses incidental
thereto, the Company will make and deliver in lieu of such Note a new Note of
like tenor and principal amount and dated as of the original date of this
