Item 5. Other Events On June 4, 2001, Mr. Charles E. Fioretti resigned as the Chairman of the Board and as an employee of Mannatech. Mr. Fioretti will however, continue to serve as a director on Mannatech's Board of Directors. On June 4, 2001, the Board of Directors accepted Mr. Fioretti's resignation and as a result, Mannatech entered into a Separation Agreement and Full and Final Release (the "Separation Agreement") with Mr. Fioretti. Under the terms of the Separation Agreement, Mannatech agreed to pay Mr. Fioretti $600,000 on June 11, 2001 and June 4, 2002, respectively. In addition, on June 4, 2001, Mr. Fioretti will sell 50,000 shares of his common stock to Mannatech at a price of $1.45 per share, which was the closing price on June 4, 2001. The Lock-up Agreement dated August 8, 2000 with Mr. Fioretti will continue; however, the terms of the Renewal and Extension Promissory Note with Mr. Fioretti dated February 17, 1999 will be modified to continue to accrue interest at 6.0%, with the remaining principal of $127,121.47 plus accrued interest due the earlier of (i) February 17, 2011 or (ii) thirteen days after the date in which Mr. Fioretti no longer owns at least 100,000 shares of Mannatech's common stock.

RECITALS -------- WHEREAS, Fioretti currently is employed by the Company; WHEREAS, Fioretti currently is a stockholder of the Company; WHEREAS, the parties entered an Agreement pertaining to Fioretti's employment with the Company on May 14, 1997 (the "1997 Employment Agreement"); WHEREAS, Fioretti and the Company entered into an Agreement on August 8, 2000 regarding the sale and purchase of certain of Fioretti's shares of Company stock (the "2000 Stand-Still Agreement"); WHEREAS, Fioretti currently serves as Chairman of the Board of Directors of the Company under an Employment Agreement entered into between the parties on September 21, 2000 (the "2000 Employment Agreement"); WHEREAS, Fioretti and the Company mutually wish to terminate Fioretti's employment relationship with the Company, subject to the terms and conditions of this Agreement; WHEREAS, Fioretti and the Company mutually wish to cancel the 1997 Employment Agreement and the 2000 Employment Agreement and all other agreements between the parties, other than those matters expressly excepted herein, so that any and all obligations under any of the cancelled agreements shall become null and void; WHEREAS, Fioretti desires to transfer certain shares of common shares of Company stock to the Company and the Company desires to accept such shares from Fioretti, subject to the terms and conditions of this Agreement; NOW THEREFORE, in exchange for the valuable consideration paid or given under this Agreement, the receipt, adequacy, and sufficiency of which is hereby acknowledged, the parties knowingly and voluntarily agree to the following terms: TERMS ----- 1. Voluntary Resignation of Employment and Position as an Officer. In -------------------------------------------------------------- consideration of the parties' mutual undertakings set forth in this Agreement, Fioretti hereby submits, and the Company hereby accepts, the voluntarily resignation of Fioretti's employment with the Company effective as of the date this Agreement is signed (the "Separation Date"). As of that time, SEPARATION AGREEMENT AND FULL AND FINAL RELEASE - Page 1

the parties agree that Fioretti will be relieved of further duties in his position as Chairman of the Board for the Company. 2. Sale of Stock and Cancellation of Prior Agreements. In consideration -------------------------------------------------- of the parties' mutual undertakings set forth in this Agreement, including but not limited to the Company's payment to Fioretti of $1,200,000 in accordance with the terms of the Special Separation Benefit described in paragraph 3 below, the parties agree that Fioretti shall sell, transfer, and deliver to the Company, and the Company shall accept from Fioretti, 50,000 shares of Company common stock on a date that is on or before the fifth day from the Effective Date of this Agreement (as defined below); provided, however, that in the event such date is on a day that the United States securities markets are not open for trading, the date shall be extended to the next succeeding trading day, as of which Fioretti shall deliver to the Company a certificate or certificates representing the 50,000 shares, together with a stock power, duly executed in blank and shall take all such action as may be reasonably requested by the Company to effect a valid transfer of the shares. In addition, the 1997 Employment Agreement, the 2000 Employment Agreement, and all other agreements between the parties, other than the 2000 Stand-Still Agreement and the Renewal and Extension Promissory Note dated February 17, 1999 made by Fioretti in the principal amount of $199,896.10 (the "Agri-Tech Note"), shall be cancelled as of the Effective Date of this Agreement (as defined below) and that, upon cancellation, any and all obligations under any of the agreements just described as cancelled shall become null and void, including but not limited to any and all provisions under said cancelled agreements otherwise purported to survive termination thereof. The transfer of shares of Company common stock pursuant to this Paragraph 2 shall in no way modify the rights or obligations of the parties pursuant to the 2000 Stand-Still Agreement. Further in consideration of the parties' mutual undertakings set forth in this Agreement, Fioretti and the Company hereby modify the payment terms of the Agri-Tech Note by amending the second and third paragraphs of the Agri-Tech Note to read in their entirety as follows: "This Note shall bear interest at six percent (6%) per annum, compounded annually on February 17 of each year. This principal and interest shall be payable as follows: On February 17, 2000, the Maker shall pay an installment of principal and interest to the Payee in the amount of $47,507.70; on February 17, 2001, the Maker shall pay an installment of principal and interest to the Payee in the amount of $47,507.70; and the Maker shall pay all remaining principal, all accrued interest, and any and all amounts due and owing under this Note to the Payee on the earlier of (i) the thirtieth day after the "Divestiture Date" (as defined below) and (ii) February 17, 2011. The "Divestiture Date" shall mean the first date on which Maker no longer owns at least 100,000 shares of Payee common stock, subject to appropriate adjustment of such number to reflect any stock splits or reverse stock splits effected by Payee after June 1, 2001. For purposes of the preceding sentence, Maker shall be SEPARATION AGREEMENT AND FULL AND FINAL RELEASE - Page 2

deemed to own only those shares of Payee common stock of which he is both the record and beneficial owner." Until the Agri-Tech Note is paid in full, Fioretti shall notify the Company in writing each time that he sells, assigns, contributes, transfers or otherwise disposes of ("sells," and each such transaction a "sale") Company common stock (other than sales to the Company) no later than 5 days following the date of each sale. Such notice shall include the date of the transaction, a brief description of the transaction, the number of shares sold, and the number of shares owned by Fioretti after the transaction. 3. Special Separation Benefit. In consideration of Fioretti's undertakings -------------------------- set forth in this Agreement, the Company agrees to provide Fioretti a Special Separation Benefit on the following terms: (a) To pay Fioretti a total of $1,200,000 in two installments according to the following schedule: one installment of $600,000 within five days from the Effective Date of this Agreement (as defined below) and one installment of $600,000 on the date that is one year from the Effective Date of this Agreement (as defined below). Both installments shall be wired on the payment date to the account of Fioretti identified in Exhibit A to this Agreement unless written notice of a different account is provided to the Company at least one business day prior to the actual wire transfer. (b) To reimburse Fioretti on a monthly basis for the excess of the actual amount of the monthly COBRA continuation coverage premiums he pays for continued medical and dental coverage, if any, under the Company's medical plan and dental plans for himself and his dependents to the extent of any dependents so covered as of the Effective Date for up to 18 months of said coverage (or for such time as he remains eligible for said coverage) over and above the amount he otherwise would have paid for said coverage had he remained employed by the Company during those months; provided, however, that Fioretti elects COBRA continuation coverage by completing and returning within the time allowed by applicable law the COBRA election form that he will receive under separate cover and keeps said coverage in effect by making timely premium payments; and provided further that if Fioretti loses his right to the continued medical and dental coverage under COBRA referred to herein solely due to the Company's termination of the plan or plans providing such coverage prior to the time such coverage would otherwise have expired, the Company shall continue to reimburse Fioretti on a monthly basis in the same monthly dollar amount until Fioretti's rights to continued coverage under COBRA with respect to such plan or plans would have expired but for the plan termination. (c) To allow Fioretti to use the office assigned him during his employment with the Company at the Company's facility at 600 South Royal Lane, Suite, 200, Coppell, Texas 75019 through August 31, 2001 (or only for as long as the Company continues to maintain said office space, if earlier than August 31, 2001, in which case the SEPARATION AGREEMENT AND FULL AND FINAL RELEASE - Page 3

Company agrees to give Fioretti, if possible, no less than seven days advance notice of the date as of which the office space must be vacated). During such period or until Fioretti gives notice to the Company that the office has been vacated, if earlier, the Company agrees that it will not change the telephone numbers of the telephones currently in use in said office, disturb the contents of said office or change the locks and will not give other personnel access to said office except for purposes of normal maintenance and building emergencies. For 90 days following the date as of which Fioretti vacates the Company's office space, the Company agrees to forward to Fioretti at such forwarding address as Fioretti may provide to the Company all mail, faxes and other communications and deliveries received by the Company for the attention of Fioretti. All such items shall be sent to Fioretti on a weekly basis in a timely fashion. Notwithstanding the preceding, the Company shall have the right to refuse receipt of any item that it determines to be of a size or weight or other characteristic that would make it burdensome, costly or otherwise inappropriate to forward but shall instead, where reasonably possible, provide the sender with the forwarding address provided to the Company by Fioretti, or in the alternative the Company may accept delivery and charge Fioretti the cost of shipping said item to Fioretti's forwarding address. (d) To allow Fioretti during his lifetime to purchase Company products at the same costs charged to Company employees; provided, however, that such purchases are limited to Fioretti's personal use and may not be resold by him. All such purchases shall be made by Fioretti by providing written notice (including email or fax) to the administrative assistant to the Company's Chief Executive Officer as to the items needed and the address for delivery and shall include a valid credit card to which the payment shall be charged. (e) To allow Fioretti during his lifetime to use the Company's fitness center on the same basis and in the same manner as provided to Company employees. All amounts payable by the Company hereunder shall be subject to lawful deductions not to exceed 20% of the gross amount payable. In the event of Fioretti's death prior to receipt of any payments owed by the Company to Fioretti hereunder, the Company will make such payments to Fioretti's estate. If Fioretti exercises his limited right to revoke his release of his Age Discrimination in Employment Act claims as provided in this Agreement and under applicable law, he understands and agrees that he will be eligible to receive the payments described above in subparagraph (a), but will not be eligible to receive the payments and benefits of the Special Separation Benefit described in subparagraphs (b), (c), (d), or (e) of this Paragraph 3. By executing this Agreement, Fioretti acknowledges and agrees that neither the Company nor any of the Released Parties (as defined below) have any legal obligation to provide the Special Separation Benefit to him. Fioretti also acknowledges and agrees that his acceptance of the Special SEPARATION AGREEMENT AND FULL AND FINAL RELEASE - Page 4

Separation Benefit and attendant obligations as described in this Agreement are in consideration of the Company's promises and undertakings set forth in this Agreement. 4. Tax Matters and Indemnities. Fioretti agrees that he is solely --------------------------- responsible for the payment of any federal, state, or local tax, if any, on all payments and benefits provided herein. If any claim is ever made upon the Company and/or any of the other Released Parties (as defined below) for tax liability on such amounts, except for the amount, if any, withheld for taxes by the Company, Fioretti agrees to indemnify and hold harmless the Company and the other Released Parties (as defined below) for such claims, including but not limited to penalties, interest, costs, and attorney's fees. Fioretti further agrees that should the characterization of any payments hereunder be found improper or unwarranted by any taxing authority such that (i) a claim is made against the Company or any of the other Released Parties (as defined below) for taxes, penalties, or interest for which Fioretti would have been initially responsible and which should have been deducted from the payment amounts, then Fioretti shall indemnify and hold harmless the Company and the other Released Parties (as defined below) for such claims, including but not limited to penalties, interest, costs, and attorney's fees; or (ii) Fioretti is held obligated to pay additional taxes, penalties, or interest, then he will not assert, file, or make any claims against the Company or any of the other Released Parties for any such taxes, penalties, or interest he may be compelled to pay or for the costs or attorney's fees he may incur. 5. Agreement Not to Use or Disclose Confidential Information. Fioretti is --------------------------------------------------------- notified that "Confidential Information" includes information disclosed to him or known by him through his employment with the Company, not generally known in the Company's industry, about Company's products, processes, and services, including but not limited to information concerning inventions, research and development, as well as all data or information concerning customers (including Associates), customer lists (including downline reports and similar reports of business activities and relevant information concerning persons who conduct the same), prospect lists, mailing lists, sales leads, contracts, financial reports, sales, purchasing, price lists, product costs, marketing programs, marketing plans, business relationships, business methods, accounts payable, accounts receivable, accounting procedures, control procedures, and training materials.

obtain a court order or other reliable assurance that confidential treatment will be accorded to the disclosed information. Fioretti recognizes that the unauthorized use or disclosure of any of the Company's Confidential Information or Trade Secrets obtained by him during his employment with the Company constitutes unfair competition. Fioretti promises not to engage in any unfair competition with the Company and understands that engaging in unfair competition with the Company is a material breach of this Agreement entitling the Company to receive injunctive relief to prevent further use and disclosure in addition to other remedies available to it in law or in equity for breach of this Agreement, and that Fioretti consents that no bond in excess of $1,000 shall be necessary for obtaining such injunctive relief. 6.

The Company's offer of the Special Separation ------------------- Benefit will expire at 12:01 a.m. on the twenty-second day following the date on which Fioretti receives this Agreement for consideration, i.e., on June 13, 2001. Fioretti may accept this offer at any time before expiration by signing this Agreement in the space provided below, and returning it to the Company. Fioretti and the Company agree that the modifications that have been made to this Agreement since Fioretti first received it for consideration do not re- start or extend the time period during which the offer remains open. 20. Limited Revocation Rights and Effective Date. For a period of seven -------------------------------------------- days after Fioretti executes this Agreement, he may, as provided by applicable law, revoke his agreement to waive any and all claims, if any, that arise in any way under the Age Discrimination in Employment Act, if he wishes, by so notifying the Chief Executive Officer of the Company in writing. This Agreement will become fully effective and enforceable after the parties execute it (the "Effective Date"); provided, however, that Fioretti's agreement to waive any and all claims, if any, that arise in any way under the Age Discrimination in Employment Act, will not become fully effective and enforceable until seven days after Fioretti executes this Agreement; and provided further that Fioretti has not exercised his limited revocation rights as provided under this Agreement and applicable law. If Fioretti revokes the release as to Age Discrimination in Employment Act claims, he understands and agrees that (i) the General Release in Paragraph 8 remains valid as to all other claims released in that Paragraph; and (ii) the total Special Separation Benefit payable to Fioretti by this Agreement shall be limited by the terms of Paragraph 23 below. 21. Knowing and Voluntary Agreement. Fioretti acknowledges that this ------------------------------- Agreement does not waive any rights or claims against the Company or any of the other Released Parties that may arise under the Age Discrimination in Employment Act after the Effective Date of this Agreement, and that the consideration provided to him for execution of this Agreement is in addition to anything of value to which he already is or may have been entitled. Fioretti further acknowledges that he has been given a period of at least 21 days within which to consider this Agreement; that he has been advised in writing to consult with his attorney prior to executing this Agreement; that this Agreement has been read and explained to him by his attorney; that he fully understands the meaning SEPARATION AGREEMENT AND FULL AND FINAL RELEASE - Page 11

Finally, Fioretti acknowledges that in executing this Agreement he is not relying on any promise, representation, or warranty whatever, express, implied, or statutory, not contained in this Agreement concerning the Agreement's subject matter, but instead is relying on his own judgment in consultation with his attorney. 22. Entire Agreement. Except as provided in paragraph 2 hereof, this ---------------- Agreement supersedes and cancels any previous negotiations, agreements, commitments, and writings between the parties regarding the Agreement's subject matter. It also contains and constitutes the entire understanding and agreement between the parties and may be modified only by a writing of contemporaneous or subsequent date executed by both Fioretti and an authorized official of the Company. 23. Breach of Agreement and Remedies. Fioretti acknowledges and agrees that -------------------------------- should he fail to comply with any of his obligations set forth in this Agreement prior to receiving the payments and benefits of the Special Separation Benefit described in Paragraph 3 above, the Company, in addition to any other legal or equitable remedy available, will have no obligation to pay Fioretti the Special Separation Benefit, except as provided below; but that all other provisions of this Agreement shall remain in full force and effect. In addition, if Fioretti exercises his limited right to revoke his release of his Age Discrimination in Employment Act claims as provided in this Agreement, he understands and agrees that he will be eligible to receive the payments and benefits of the Special Separation Benefit described in subparagraph (a) of Paragraph 3, but will not be eligible to receive the payments and benefits of the Special Separation Benefit described in subparagraphs (b),(c), (d), or (e) of Paragraph 3. Fioretti further understands and agrees that in the event of such a revocation, all other provisions of this Agreement shall remain in full force and effect. In the event that Fioretti shall obtain any money judgment or otherwise prevail with respect to any litigation brought by Fioretti to enforce any provision contained herein, the Company shall reimburse Fioretti for his reasonable attorneys' fees, expert witness fees and disbursements incurred in such litigation. 24. Indemnification; Continuation of Insurance. The Bylaws of the Company ------------------------------------------ provide for the indemnification of its officers and directors in their capacity as such. The Company agrees that it will continue to include Fioretti within the provisions for indemnification of officers and directors of the Company in its Bylaws on and after the Effective Date of this Agreement with respect to his services as such on the same basis as provided for its officers and directors generally. The Company further agrees to continue to include Fioretti on and after the Effective Date of this Agreement in the directors and officers liability insurance policy covering other directors and officers of the Company generally in place from time to time. In no event shall Fioretti be entitled to indemnification under this paragraph with respect to any proceeding, or matter therein, brought or made by Fioretti against the Company. 25. Mitigation.

26. No Other Agreements. Fioretti acknowledges that neither the Company ------------------- nor any agent or attorney for the Company has made any promise, representation, or warranty whatever, express, implied, or statutory, not contained in this Agreement concerning the Agreement's subject matter to induce Fioretti to execute this Agreement, and Fioretti acknowledges that he has not executed this Agreement in reliance on any such promise, representation, or warranty not contained herein. Fioretti represents and warrants that he has not assigned or transferred, or purported to assign or transfer, to any person or entity not a party any claim, debt, covenant, agreement, contract, liability, demand, obligation, account, expense, action, cause of action, or suit being released under this Agreement. Fioretti further agrees to indemnify and hold harmless the Company and the other Released Parties against any claim, debt, loss, covenant, agreement, contract, liability, demand, obligation, account, expense, action, cause of action, or suit (including the payment of attorney's fees and costs reasonably incurred, whether or not litigation is commenced) by any person or entity that is not a party to this Agreement, which is inconsistent with any of the warranties, representations, or covenants made by Fioretti in this Agreement.
