The Maker and any endorsers, sureties, guarantors, and all others who are, or may become liable for the payment hereof, (a) severally waive presentment for payment, demand, notice of protest of this Promissory Note, and all other notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Promissory Note, (b) expressly consent to all extensions of time, renewals, postponements of time of payment of this Promissory Note or other modifications hereof from time to time prior to or after the day they became due without notice, consent or consideration to any of the foregoing, (c) expressly agree to the addition or release of any party or person primarily or secondarily liable hereon, (d) expressly agree that the Payee shall not be required first to institute any suit, or to exhaust its remedies against the undersigned or any other person or party to become liable hereunder in order to enforce the payment of this Promissory Note, and (e) expressly agree that, notwithstanding the occurrence of any of the foregoing (except the express written release by the Payee of any such person), the Maker shall be and remain, directly and primarily liable for all sums due under this Promissory Note.

Notwithstanding any other provisions of this Promissory Note or any other instrument executed in connection with the loan evidenced here by, it is expressly agreed that the amounts payable under this Promissory Note or under the other aforesaid instruments for the payment of interest or any other payment in the nature of or which would be considered as interest or other charge for the use or loan of money shall not exceed the highest rate allowed by the laws of the State of Florida, from time to time, and in the event the provisions of this Promissory Note or of such other instrument referred to above in this paragraph with respect to the payment of interest or other payments in the nature of or which would be considered as interest or other charge for the use or loan of money shall result in exceeding such limitation, then the excess over such limitation shall not be payable and the amount otherwise agreed to have been paid shall be reduced by the excess so that such limitation will not be exceeded. If any payment is actually made which shall result in such limitation being exceeded, the amount of the excess shall constitute and be treated as a payment on the principal hereof and shall operate to reduce such principal by the amount of such excess, or if in excess of the principal indebtedness, such excess shall be refunded.

This Promissory Note shall be construed in accordance with the laws of the State of Florida.

MAKER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES THE RIGHT EITHER MAY HAVE TO A TRIAL BY JURY IN RESPECT TO ANY LITIGATION BASED HEREUNDER, OR ARISING OUT OF, OR IN CONNECTION WITH THIS PROMISSORY NOTE OR ANY DOCUMENT EXECUTED IN CONNECTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN), OR ACTIONS OF EITHER THE MAKER OR LENDER.
