Interest shall be computed on the actual number of days elapsed and an assumed year of 360 days. Borrower and all endorsers, sureties, guarantors and any other persons liable or to become liable with respect to the loan evidenced by this Note (the "Loan") are each included in the term "Obligors" as used in this Note. Said principal and interest shall be payable in lawful money of the United States, on the dates and in the amounts specified below, to wit: (a) On May 10, 1997, and on the tenth (10th) day of each successive calendar month thereafter, through and including March 10, 2000, an installment of principal and interest equal to __Five Thousand Two Hundred Sixty Seven__ AND __73__/100 DOLLARS ($___5,267.73___) will be due and payable; and (b) On April 10, 2000, the entire outstanding principal balance hereof, together with accrued but unpaid interest thereon, will be due and payable ("Maturity Date"). Borrower shall pay to Bank a late charge of five percent (5%) of any payment not received by Bank within fifteen (15) days of its due date; provided, however, if said fifteen (15) day period ends on a day other than a day on which Bank is open for business (a "Business Day"), then the aforedescribed late charge shall be payable if the payment is not received by the last Business Day within said fifteen (15) day period. This Note may be prepaid in whole or at any time without penalty. Borrower shall pay all amounts owing under this Note in full when due without set-off, counterclaim deduction or withholding for any reason whatsoever. If any payment falls due on a day other than a Business Day, then such payment shall instead be made on the next succeeding Business Day, and interest shall accrue accordingly. Any payment received by Bank after 1:00 p.m. shall not be credited against the indebtedness under this Note until at least the next succeeding Business Day. If default be made in the payment of any sums payable pursuant to the terms of this Note, or if default or other event causing the acceleration of this Note, that certain Promissory Note in the amount of $750,000 of even date herewith executed by Aquagenix Land-Water Technologies, Inc. ("Line of Credit Note") or any other instrument or document executed in connection with the Loan (this Note, the Line of Credit Note, and all such instruments and documents, including, without limitation, any guaranties, agreements, mortgages, security agreements, assignments and other documents securing this Note, are referred to in this Note as the "Loan Documents") (an "Event of Default"), then or at any time thereafter at the option of Bank, the whole of the principal sum then remaining unpaid hereunder, together with all interest accrued thereon and all other sums owing under the Loan Documents, shall immediately become due and payable without notice and Bank shall be entitled to pursue any and all rights and remedies provided by applicable law and/or under the terms of this Note or any other Loan Document, all of which shall be cumulative and may be exercised successively or concurrently. Upon the occurrence and during the continuation of any Event of Default, Bank, at its option, may at any time declare any or all other liabilities of any Obligor to Bank immediately due and payable 1 (notwithstanding any contrary provisions thereof) without demand or notice of any kind. In addition, Bank shall have the right to set off any and all sums owed to any Obligor by Bank in any capacity (whether or not then due) against the Loan and/or against any other liabilities of any Obligor to Bank. From and after an Event of Default, and regardless of whether the Bank also elects to accelerate the maturity of this Note, the entire principal remaining unpaid hereunder shall bear an augmented annual interest rate equal to the lesser of (i) twenty-five percent (25%) per annum, or (ii) the highest applicable lawful rate. Failure to exercise any and all rights or remedies Bank may in the event of any such default be entitled to shall not constitute a waiver of the right to exercise such rights or remedies in the event of any subsequent default, whether of the same or different nature. No waiver of any right or remedy by Bank shall be effective unless made in writing and signed by Bank, nor shall any waiver on one occasion apply to any future occasion. In no event shall any agreed or actual exaction charged, reserved or taken as an advance or forbearance by Bank as consideration for the Loan exceed the limits (if any) imposed or provided by the law applicable from time to time to the Loan for the use or detention of money or for forbearance in seeking its collection, and Bank hereby waives any right to demand such excess. In the event that the interest provisions of this Note or any exactions provided for in this Note or any other Loan Document shall result at any time or for any reason in an effective rate of interest that transcends the maximum interest rate permitted by applicable law (if any), then without further agreement or notice the obligation to be fulfilled shall be automatically reduced to such limit and all sums received by Bank in excess of those lawfully collectible as interest shall be applied against the principal of the Loan immediately upon Bank's receipt thereof, with the same force and effect as though the payor had specifically designated such extra sums to be so applied to principal and Bank had agreed to accept such extra payment(s) as a premium-free prepayment or prepayments. During any time that the Loan bears interest at the maximum lawful rate (whether by application of this paragraph, the default provisions of this Note or otherwise), interest shall be computed on the basis of the actual number of days elapsed and the actual number of days in the respective calendar year. The Obligors hereby severally: (a) waive demand, presentment, protest, notice of dishonor, suit against or joinder of any other person, and all other requirements necessary to charge or hold any Obligor liable with respect to the Loan; (b) waive any right to immunity from any such action or proceeding and waive any immunity or exemption of any property, wherever located, from garnishment, levy, execution, seizure or attachment prior to or in execution of judgment, or sale under execution or other process for the collection of debts; (c) waive any right to interpose any set-off or non-compulsory counterclaim or to plead laches or any statute of limitations as a defense in any such action or proceeding and waive (to the extent lawfully waivable) all provisions and requirements of law for the benefit of any Obligor now or hereafter in force; (d) submit to the jurisdiction of the state and federal courts in the State of Florida for purposes of any such action or proceeding; (e) agree that the venue of any such action or proceeding may be laid in Dade County, Florida (in addition to any county in which any collateral for the Loan is located), and waive any claim that the same is an inconvenient forum; (f) stipulate that service of process in any such action or proceeding shall be properly made if mailed by any form of registered or certified mail (airmail if international), postage prepaid, to the address then registered in Bank's records for the Obligor(s) so served, and that any process so served shall be effective ten (10) days after mailing; and (g) agree that the death or mental or physical incapacity of any Obligor who is a natural person, or the dissolution or merger or consolidation or termination of the existence of any Obligor that is a business entity (or if any person controlling such Obligor shall take any action authorizing or leading to the same), shall at Bank's option, which option may be exercised then or at any time thereafter, result in the Loan being then due and payable in full. No provision of this Note shall limit Bank's right to serve legal process in any other manner permitted by law or to bring any such action or proceeding in any other competent jurisdiction. The Obligors hereby severally consent and agree that, at any time and from time to time without notice, (i) Bank and the owners(s) of any collateral then securing the Loan may agree to release, increase, change, substitute or exchange all or any part of such collateral, and (ii) Bank and any person(s) then primarily liable for the Loan may agree to renew, extend or compromise the Loan in whole or in part or to modify the terms of the Loan in any respect whatsoever; no such release, increase, change, substitution, exchange, renewal, extension, compromise or modification shall release or affect in any way the liability of any Obligor, and the Obligors hereby severally waive any and all defenses and claims 2 whatsoever based thereon. Until Bank receives all sums due under this Note and all other Loan Documents in immediately available funds, no Obligor shall be released from liability with respect to the Loan unless Bank expressly releases such Obligor in a writing signed by Bank, and Bank's release of any Obligor(s) shall not release any other person liable with respect to the Loan. The interest rate charged is authorized by Florida Statutes, Chapter 665.
