12.  Usury Limitations.  It is the intention of the parties to conform strictly to applicable usury laws from time to time in force, and all agreements between Borrower and Lender, whether now existing or hereafter arising and whether oral or written, are hereby expressly limited so that in no contingency or event whatsoever, whether by acceleration of maturity hereof or otherwise, shall the amount paid or agreed to be paid to Lender, or collected by Lender, for the use, forbearance or detention of the money to be loaned hereunder or otherwise, exceed the maximum amount permissible under applicable usury laws.  If under any circumsta nces whatsoever fulfillment of any provision hereof or any other Loan Documents, at the time performance of such provision shall be due, shall involve an amount or any portion thereof in excess of the limit of validity prescribed by law, then ipso facto, the payment to be made or the amount to be delivered to be fulfilled shall be reduced to the limit of such validity; and if under any circumstances Lender shall ever receive an amount deemed interest, by applicable law, which would exceed the highest lawful rate, such amount that would be excessive interest under applicable usury laws shall be applied to the reduction of the principal amount owing hereunder and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal and other indebtedness, the excess shall be deemed to have been a payment made by mistake and shall be refunded to Borrower or to any other person making such payment on Borrower's behalf.  All sums paid or agreed to be paid to Lender for th e use, forbearance or detention of the indebtedness of Borrower evidenced hereby, outstanding from time to time shall, to the extent permitted by applicable law, be amortized, pro-rated, allocated and spread from the date of disbursement of the proceeds of this Note until payment in full of such indebtedness so that the actual rate of interest on account of such indebtedness is uniform through the term hereof.  The terms and provisions of this paragraph shall control and supersede every other provision of all agreements between Lender and Borrower and any endorser or guarantor of this Note.

13.  Severability.  In case any provision (or any part of any provision) contained in this Note shall for any reason be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision (or remaining part of the affected provision) of this Note, but this Note shall be construed as if such invalid, illegal, or unenforceable provision (or part thereof) had never been contained herein but only to the extent it is invalid, illegal, or unenforceable.

 

14.  Governing Law.  Borrower hereby acknowledges, consents and agrees (i) that the provisions of this Note and the rights of all parties mentioned herein shall be governed by the laws of the State of Florida and interpreted and construed in accordance with such laws (excluding the conflict of laws for the State of Florida) and (ii) that venue for any proceeding instituted to enforce this Note shall lie in Palm Beach County, Florida, and any objections to such jurisdiction or venue are hereby waived.

 

15. No Waiver by Lender.  No failure on the part of Lender to exercise any right or remedy hereunder, whether before or after the happening of a default shall constitute a waiver thereof, and no waiver of any past default shall constitute a waiver of any future default or of any other default.  No failure to accelerate the debt evidenced hereby by reason of default hereunder, or acceptance of a past due installment, or indulgence granted from time to time shall be construed to be a waiver of the right to insist upon prompt payment thereafter or to impose late charges retroactively or prospectively, or shall be deemed to be a novation of t his Note or as a reinstatement of the debt evidenced hereby or as a waiver of such right or acceleration or any other right, or be construed so as to preclude the exercise of any right that Lender may have, whether by the laws of the State of Florida, by agreement, or otherwise.  This Note may not be changed orally, but only by an agreement in writing signed by the party against whom such agreement is sought to be enforced.

 

16. No Offsets.  No indebtedness evidenced by this Note shall be deemed to have been offset or shall be offset or compensated by all or part of any claim, cause of action, counterclaim or cross-claim, whether liquidated or unliquidated, which Borrower may have or claim to have against Lender now or hereafter.  Furthermore, in respect to the present indebtedness of, or any future indebtedness incurred by, Borrower to Lender, Borrower waives, to the fullest extent permitted by law, the benefits of any applicable law, regulation or procedure that substantially provides that, if (i) cross-demands for money have existed between persons at any point in time and (ii) neither demand was barred by the applicable statute of limitations and (iii) an action is thereafter commenced by one such person, then the other may assert in his answer the defense of payment in that the two demands are compensated so far as they equal each other, notwithstanding that an independent action asserting the claim would at the time of filing the answer be barred by the applicable statute of limitations.

17.  Loss, Theft, Destruction or Mutilation of Note.  In the event of the loss, theft or destruction of this Note, upon Lender's written request, accompanied by an indemnification and/or security reasonably satisfactory to Borrower, or in the event of the mutilation of this Note, upon Lender's surrender to the Borrower of the mutilated Note, Borrower shall execute and deliver to such party or Lender, as the case may be, a new promissory note in form and content identical to this Note in lieu of the lost, stolen, destroyed or mutilated Note.

18.  Relationship of Parties.  THE RELATIONSHIP BETWEEN BORROWER AND LENDER IS, AND AT ALL TIMES SHALL REMAIN, SOLELY THAT OF DEBTOR AND CREDITOR, AND SHALL NOT BE, OR BE CONSTRUED TO BE, A JOINT VENTURE, EQUITY VENTURE, PARTNERSHIP OR OTHER RELATIONSHIP OF ANY NATURE.

19. Unconditional Payment.  If any payment received by Lender hereunder shall be deemed by a court of competent jurisdiction to have been a voidable preference or fraudulent conveyance under any bankruptcy, insolvency or other debtor relief law, then the obligation to make such payment shall survive any cancellation or satisfaction of this Note or return thereof to Borrower and shall not be discharged or satisfied with any prior payment thereof or cancellation of this Note, but shall remain a valid and binding obligation enforceable in accordance with the terms and provisions hereof, and such payment shall be immediately due and payable upon demand .  No release of any security for this Note or any party liable for payment of this Note shall release or affect the liability of Borrower or any other party who may become liable for payment of all or any part of the indebtedness evidenced by this Note.  Lender may release any guarantor, surety or indemnitor of this Note from liability, in every instance without the consent of Borrower hereunder and without waiving any rights which Lender may have hereunder or under the Loan Agreement or under applicable law or in equity.
