                                            become unlawful for either the Maker or the Holder to maintain this Note or for the Maker
                                            to perform any of its obligations thereunder, or if this Note shall cease to be effective
                                            and enforceable in accordance with its terms; (v) in the event that the Maker materially

		7.2	If
                                            an event of default specified in Clause 7.1 occurs, the Holder may, but with no obligation
                                            to do so and without incurring any liability to the Maker, declare by written notice to the

                                            Upon the occurrence of an event of default, interest on the Principal and all accrued and
                                            unpaid interest shall accrue at a rate two hundred (200) basis higher than the interest rate
                                            in effect immediately prior to the occurrence of the event of default. The Holder shall have
                                            the right to institute any suit, action or proceeding in equity or at law to enforce its
                                            rights under this Note.

 

		7.3	It
                                            is the intent of the Maker and the Holder that in no event shall interest be payable at a
                                            rate in excess of the maximum rate permitted by applicable law. Solely to the extent necessary
                                            to prevent interest under this Note from exceeding the maximum legal rate, the Maker agrees
                                            that any amount that would be treated as excessive under a final judicial interpretation
                                            of applicable law shall be deemed to have been a mistake and automatically cancelled, and,
                                            if received by the Holder, shall be refunded to the Maker, without interest.
