         7. MAXIMUM RATE OF INTEREST. It is expressly stipulated and agreed to
be the intent of the Company and Holder at all times to comply with the
applicable law governing the maximum rate of interest payable on or in
connection with all indebtedness and transactions hereunder (or applicable
United States federal law to the extent that it permits Holder to contract for,
charge, take, reserve or receive a greater amount of interest). If the
applicable law is ever judicially interpreted so as to render usurious any
amount of money or other consideration called for hereunder, or contracted for,
charged, taken, reserved or received with respect to any loan or advance
hereunder, or if acceleration of the maturity of this Note or the indebtedness
hereunder or if any prepayment by the Company results in the Company's having
paid any interest in excess of that permitted by law, then it is the Company's
and Holder's express intent that all excess cash amounts theretofore collected
by Holder be credited on the principal balance of this Note (or if this Note has
been or would thereby be paid in full, refunded to the Company), and the
provisions of this Note immediately be deemed reformed and the amounts
thereafter collectible hereunder reduced, without the necessity of the execution
of any new document, so as to comply with the applicable law, but so as to
permit the recovery of the fullest amount otherwise called for hereunder. The
right to accelerate maturity of this Note does not include the right to
accelerate any interest which has not otherwise accrued on the date of such
acceleration, and Holder does not intend to collect any unearned interest in the
event of acceleration.

         8. NO IMPLIED WAIVER. No failure or delay on the part of Holder in
exercising any right, power or privilege under this Note and no course of
dealing between the Company and Holder shall operate as a waiver thereof. No
single or partial exercise of any right, power or privilege hereunder shall
preclude any other or further exercise of any right, power or privilege Holder
would otherwise have. No notice to, or demand on, the Company in any case shall
entitle the Company to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the right of Holder to any other or
further action in any circumstances without notice or demand.

         9. GOVERNING LAW. THIS AGREEMENT SHALL BE CONSTRUED ACCORDING TO THE
LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE PRINCIPLES THEREOF
RELATING TO CONFLICTS OF LAWS.
