The
failure of Holder or any subsequent holder hereof to exercise any of the remedies or options set forth in this Note, upon the
occurrence of one or more events of default, shall not constitute a waiver of the right to exercise the same or any other remedy
at any subsequent time in respect to the same or any other event of default.  The acceptance of the Holder hereof of any
payment which is less than the total of all amounts due and payable at the time of such payment shall not constitute a waiver
of the right to exercise any of the foregoing remedies or options at that time or any subsequent time, or nullify any prior exercise
of any such remedy or option, without the express consent of the Holder hereof, except as and to the extent otherwise provided
by law. 


 


Maker
and Holder intend and believe that each provision in this Note comports with all applicable local, state and federal laws and
judicial decisions.  However, if any provision or provisions, or if any portion of any provision or provisions, in this Note
is found by a court of law to be in violation of any applicable local, state or federal ordinance, statute, law, administrative
or judicial decision, or public policy, and if such court should declare such portion, provision or provisions of this Note to
be illegal, invalid, unlawful, void or unenforceable as written, then it is the intent of all parties hereto that such portion,
provision or provisions shall be given force to the fullest possible extent that they are legal, valid and enforceable, that the
remainder of this Note shall be construed as if such illegal, invalid, unlawful, void or unenforceable portion, provision or provisions
were not contained therein, and that the rights, obligations and interest of Maker and Holder under the remainder of this Note
shall continue in full force and effect.


 


All
notices, consents, waivers, and other communications under this Note must be in writing and will be deemed to have been duly given
when (a) delivered by hand to the addressee (with written confirmation of receipt), (b) or by registered mail, certified mail,
or a nationally recognized overnight delivery service (receipt requested) to the respective addresses of Maker and Holder set
forth in this Note or at such other address as given to the other party in writing. If sent by registered or certified mail, notice
shall be deemed given three (3) business days after the date on which it has been deposited in the United States mail
