Fioretti, an individual residing in the State of Texas ("Maker"), promises to pay to the order of Mannatech, Incorporated, a Texas corporation ("Payee"), the sum of Five Hundred Thousand Dollars ($500,000). This Note is executed in connection with that certain Note and Stock Purchase Agreement, dated of even date herewith, by and between Maker and Payee (the "Purchase Agreement") and is subject to the terms of such Purchase Agreement. Reference is hereby made to the Purchase Agreement for provisions affecting this Note regarding payment, and such provisions are hereby incorporated in this Note by reference. All payments made by Maker hereunder shall be made at such location as is directed by Payee without set-off, deduction or counterclaim. All payments shall be applied first to payment of costs and expenses (including reasonable attorneys' fees) incurred by Payee in enforcing this Note, including all costs of collection, next to payment of accrued and unpaid interest and then to the reduction principal. All past due principal and accrued interest on this Note shall bear interest from maturity until paid at the rate of the lesser of (i) eighteen percent (18%) per annum or (ii) the maximum rate of interest permitted under applicable law. A per annum rate of interest of 6.9% shall be imputed but not charged. The entire unpaid principal balance of, and all accrued interest on, this Note shall immediately be due and payable at the option of Payee (or with respect to clause (c) automatically without notice of any kind) upon the occurrence of (a) a failure by the undersigned to pay when due any installment of principal or interest under this Note or any other cost due hereunder, (b) any breach of any representation or warranty or any material breach of any covenant or agreement set forth in this Note or the Purchase Agreement on the part of Maker, (c) the commencement of a voluntary case under Title 11 of the United States Code, the filing of an answer or other pleading admitting or failing to deny the material allegations of a petition filed against Maker commencing an involuntary case under said Title 11 or the failure to controvert timely the material allegations of such petition (each such event, an "Event of Default"). No delay on the part of the holder of this Note in the exercise of any power or right under this Note or under any other instrument executed pursuant hereto shall operate as a waiver thereof, nor shall a single or partial exercise of any power or right preclude other or further exercise thereof or the exercise of any other power or right. Except as expressly otherwise provided for herein, Maker and all endorsers of this Note waive demand, presentment, protest, notice of dishonor, notice of nonpayment, notice of intention to accelerate, notice of protest and any and all lack of diligence or delay in collection or the filing of suit hereon which may occur, and agree to all extensions and partial payments, before or after maturity, without prejudice to the holder hereof. In the event that one or more Events of Default shall occur, and in the event that thereafter this Note is placed in the hands of an attorney for collection, or in the event that this Note is collected in whole or in part through legal proceedings of any nature, then and in any such case, there shall be added to the unpaid principal balance hereof all reasonable costs of collection, including but not limited to reasonable attorneys' fees, on account of such collection, whether or not suit is filed. THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS. All agreements between Maker and the holder of this Note, whether now existing or hereafter arising and whether written or oral, are expressly limited so that in no contingency or event whatsoever, whether by acceleration of the maturity of this Note or otherwise, shall the amount paid, or agreed to be paid, to the holder hereof for the use, forbearance or detention of the money to be loaned hereunder or otherwise, exceed the maximum amount permissible under applicable law. If from any circumstances whatsoever fulfillment of any provision of this Note or of any other document evidencing, securing or pertaining to the indebtedness evidenced hereby, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstances the holder of this Note shall ever receive as interest under this Note or any other document evidencing, securing or pertaining to the indebtedness evidenced hereby or otherwise an amount that would exceed the highest lawful rate, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing under this Note or on account of any other indebtedness of Maker to the holder hereof relating to this Note, and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of this Note and such other indebtedness, such excess shall be refunded to Maker. In determining whether or not the interest paid or payable with respect to any indebtedness of Maker to the holder hereof, under any specific contingency, exceeds the highest lawful rate, Maker and the holder hereof shall, to the maximum extent permitted by applicable law, (a) characterize any non- principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, (c) amortize, prorate, allocate and spread the total amount of interest throughout the full term of such indebtedness so that the actual rate of interest on account of such indebtedness is uniform throughout the term thereof, and/or (d) allocate interest between portions of such indebtedness, to the end that no such portion shall bear interest at a rate greater than that permitted by law. The terms and provisions of this paragraph shall control and supersede every other conflicting provision of all agreements between Maker and the holder hereof. All of the stipulations, promises and agreements in this Note contained by or on behalf of Maker and Payee shall bind the successors and assigns of Maker and Payee, whether so expressed or not, and inure to the benefit of the successors and assigns of Maker and Payee. In the event any one or more of the provisions 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 hereof, and this Note shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. IN WITNESS WHEREOF, the undersigned has executed this Note as of the date first above written. /s/ CHARLES E. FIORETTI --------------------------------- Charles E.
