payable in full without notice or demand upon the occurrence at any time of an
"Event of Default" under the Security Agreement or any of the following events:
(1) default in any payment of interest due hereunder, and the continuation of

they mature, or make a general assignment for the benefit of, or enter into any
composition, trust mortgage or other arrangement with creditors; (ii) apply for,
or consent (by admission of material allegations of a petition or otherwise) to
the appointment of a receiver, trustee or liquidator of the undersigned, or of a
substantial part of its assets, or authorize such application or consent, or
proceedings seeking such appointment shall be commenced against the undersigned,
and continue undismissed for sixty (60) days; or (iii) apply for, or consent (by
admission of material allegations of a petition or otherwise) to the application
of any bankruptcy, reorganization, readjustment of debt, insolvency,

application or consent, or proceedings to such and shall be instituted against
the undersigned, and remain unstayed or undismissed for sixty (60) days, be
approved as properly instituted or result in adjudication of bankruptcy or
insolvency.

         The undersigned hereby: (1) waives presentment, demand, protest and
notices of every kind and description (other than any notice of default in
payment as herein provided); (2) waives any defenses based upon, and
specifically assents to, any and all extensions and postponements of the time of
payment and all other indulgences and forbearances which may be granted by the
holder to the undersigned; and (3) agrees to be bound by all other terms
contained in this Note.

         No delay or omission on the part of CREDITOR in exercising any right
hereunder shall operate as a waiver of such right or of any other right of
CREDITOR, nor shall any delay, omission or waiver on any one occasion be deemed
a bar to or waiver of the same or any other right on any future occasion.

         No single or partial exercise of any power hereunder shall preclude
other or future exercise thereof or the exercise of any other power.
