                                PRIOR AGREEMENTS
                                ----------------


1.1  AMENDMENT. This Agreement supersedes all prior oral and written agreements
     between the Parties of any and every nature whatsoever, including, with
     specificity the Prior Agreements and any other agreements for additional
     compensation, benefits and stock except as embodied in this Agreement.
     Nothing herein shall be construed to alter or amend the obligations created
     under any Associate agreement, which creates an Associate position in the
     Mannatech downline of which Robbins is a party, including any compensation
     due to Robbins as an Associate under Mannatech's compensation plan, as it
     is currently in effect and modified from time-to-time and the obligation of
     Mannatech to reimburse or pay Robbins' reasonable travel expenses in
     connection with Mannatech business.

1.2  GRANDFATHERED POSITIONS. The Parties previously agreed to designate
     positions 6103 and 994 at Platinum Presidential status. However, because of
     various delays in integrating these positions into Mannatech's Enterprise
     computer system ("Enterprise") for reasons beyond Mannatech's control and
     without an admission of liability, the Parties have agreed that Mannatech
     shall designate ("grandfather") positions 268, 328, 741, and 947 at
     Platinum Presidential status (collectively "Grandfathered Positions")
     effective Business Period 1 (2002). Robbins understands and agrees that the
     Grandfathered Positions will not be entered into the Enterprise until on or
     about February 2002, and any and all commissions then due will be
     automatically generated through Enterprise. Robbins shall properly pay,
     when due, any and all tax liability resulting from and due any taxing
     authority on account of the effect of this Agreement, and shall indemnify
     and hold Mannatech harmless from the same.

1.3  PRIOR PAYMENT OF COMMISSIONS.  Mannatech has used its best efforts to
     manually compute any and all commissions due Robbins and for which Robbins
     has been paid from November 2000 to December 31, 2001 for positions 6103
     and 994 ("Prior Payments") . The Parties agree that all Prior Payments made
     to Robbins under the terms of the July 19, 2000 agreement are final as of
     the close of Business Period 13 (2001) and no further payments are due; and
     Robbins further agrees to discharge any obligation of Mannatech to
     grandfather positions 6103 and 994.

1.4  RELEASE. Robbins for himself and his respective representatives, successors
     and assigns, hereby fully, completely and finally releases and forever
     discharges Mannatech, its officers, directors, agents, independent sales
     associates and their heirs, personal representatives, successors and
     assigns, its attorneys, employees, subsidiaries, successors and assigns
     from any and all claims, demands, causes of action and liabilities that he
     has or may have, whether known or unknown, asserted or unasserted, existing
     as of the date of execution hereof including any liabilities relating to
     the Prior Agreements.


                                                                               2



                                   ARTICLE II
                            DUTIES & NON-COMPETITION
                            ------------------------

2.1.1 ROBBINS DUTIES. Robbins agrees that:
     2.1.2 His duties shall be those assigned and agreed to between Mannatech
           and himself from time-to-time, but shall include development of
           recruiting and Associate downline matters.
     2.1.3 He will serve Mannatech diligently, faithfully and to his ability
           during the term of this Agreement, which shall be at the will of
           Mannatech, and which shall further be subject to the announced
           Policies & Procedures of Mannatech will shall from time-to-time be in
           effect.
     2.1.4 He shall devote reasonable time, efforts, ability and attention to
           the business of Mannatech and the performance of his duties,
           understanding that he is an independent contractor for all purposes,
           including federal income tax purposes.
     2.1.5 He acknowledges and understands that from time-to-time his duties
           will require that he work at non-company locations. In such
           instances, Robbins agrees to comply with all policies, procedures and
           directives relevant to working at such non-company locations.
     2.1.6 Nothing contained in this Agreement is intended to abrogate or affect
           the right of Robbins to be paid in accordance with the Compensation
           Plan, as the same is from time-to-time in effect.
     2.1.7 He shall use his best efforts to ensure that no relative of his, nor
           any corporation or other entity of which he is an officer, principal,
           manager director or shareholder or other affiliate, shall take any
           action that he could not take without violating any term of this
           Agreement.

2.2  NON-COMPETITION/NON-SOLICITATION. Robbins agrees that in the highly
     competitive business in which Mannatech is engaged, personal contact is of
     primary importance in securing new and retaining present Associates and
     customers. Robbins also agrees that Mannatech has a legitimate interest in
     maintaining its relationships with its Associates and customers and that it
     would be unfair for Robbins to solicit the business of Mannatech's
     Associates and customers in relation to Mannatech's current business and
     exploit the personal relationships that he has developed with Mannatech's
     Associates and customers by virtue of his access to them as a result of his
     close relationship with Mannatech. To the full extent permitted by law
     following any termination of his relationship with Mannatech Robbins will
     not, for a period equivalent to his tenure with Mannatech, which at the
     time of this Agreement is five (5) years:
     2.2.1 Attempt to cause any person, firm or corporation which is a customer
           of or has a contractual relationship with Mannatech (including its
           Associates) to terminate such relationship with Mannatech. This
           provision shall apply regardless of whether such customer has a valid
           contractual arrangement with Mannatech;
     2.2.2 Attempt to cause any employee of Mannatech to leave such employment;
     2.2.3 Engage any person who was an employee of Mannatech or cause such
           person otherwise to become associated with Robbins or with any other
           person, corporation, partnership or other entity with which Robbins
           may thereafter become associated; or
     2.2.4 Engage in any activity or perform any services competitive with any
           business conducted by Mannatech in the United States which Mannatech
           operates, at the time of execution of this Agreement.
     2.2.5 Robbins represents and admits that in the event of termination of his
           consulting duties for any reason whatsoever, his experiences and
           capabilities are such that he can obtain engagement in business
           engaged in other lines and/or of a different

                                                                               3


           nature, and that the enforcement of a remedy by way of injunction
           will not prevent him from earning a livelihood.
     2.2.6 Robbins acknowledges that at the time that this non-competition
           covenant is made, that the limitations as to time defined herein and
           that the limitations as to geographic area are reasonable and do not
           impose a greater restraint than is necessary to protect the goodwill
           or other business interests of Mannatech.
     2.2.7 The agreements, noncompetition agreements, nondisclosure agreements,
           and non-solicitation agreements set forth herein each constitute
           separate agreements, independently supported by good and adequate
           consideration and shall be severable from the other provisions of
           this Agreement and shall survive the Agreement. The existence of any
           claim or cause of action of Robbins against Mannatech, whether
           predicated on this Agreement or otherwise, shall not constitute a
           defense to the enforcement by Mannatech of the covenants and
           agreements of Robbins contained in the noncompetition, nondisclosure
           or the non-solicitation agreements herein, If a court of competent
           jurisdiction determines that any restriction in a clause or provision
           of this Agreement is void, illegal or unenforceable, the other
           clauses and provisions of this Agreement shall remain in full force
           and effect and the clauses and provisions that are determined to be
           void, illegal or unenforceable shall be limited so that they shall
           remain in effect to the fullest extent allowed by law.


2.3  SPECIALIZED TRAINING. Irrespective of the term of this Agreement and in
     consideration of the promises specified in Article III, Mannatech agrees to
     provide specialized training and instruction to Robbins for duties in
     consultation of the Associate downline of Mannatech, recruitment and other
     matters as may come before the Parties from time-to-time, and agrees to
     provide specialized training to Robbins for such additional consulting
     duties as the Parties may in good faith agree in the future. Robbins
     acknowledges that he will receive special knowledge and specialized
     training from Mannatech, included in which is the CONFIDENTIAL INFORMATION
     identified in Article III. Robbins further acknowledges that training
     provided by Mannatech and the CONFIDENTIAL INFORMATION is valuable to
     Mannatech and, therefore, Mannatech's investment in the training and the
     protection and maintenance of the CONFIDENTIAL INFORMATION constitutes a
     legitimate interest to be protected by Mannatech by the covenants not to
     compete in Article 2.2.


2.4  DUTY OF GOOD FAITH & LOYALTY. Robbins acknowledges and agrees that he owes
     a fiduciary duty of loyalty, fidelity, and allegiance to act at all times
     in the best interests of Mannatech. In keeping with these duties, Robbins
     shall make full disclosure to Mannatech of all business opportunities
     pertaining to Mannatech's present business and shall not appropriate for
     his own benefit business opportunities concerning such business. The
     Parties further agree that during the term of this Agreement and
     thereafter, they will not disparage each other or their respective
     Affiliates.

     2.4.1 MANNATECH'S DUTIES. Irrespective of the term of engagement as a
           consultant, and in consideration of the promises in this Article,
           Mannatech agrees to provide specialized training as specified herein
           and to provide Robbins with access to Mannatech's software and files,
           records, marketing procedures, processes, computer programs,
           compilations of information, records, Associate and client
           requirements, pricing techniques, lists, formulae, lists identifying
           Associates, partners, potential investors, methods of doing business
           and other

                                                                               4


           CONFIDENTIAL INFORMATION which is regularly used in the operation of
           the business of Mannatech as is relevant to Robbins' engagement in
           the opinion of Mannatech.
     2.4.2 To continue to refer to Robbins in all corporate literature and
           presentations as a "founder" of Mannatech and member of the Board of
           Directors for so long as he holds such a position.

          include information disclosed to Robbins or known by Robbins and, not

          development, as well as all data or information concerning customers

          receivable, accounting procedures, control procedures and training
          materials.
     3.2  Robbins acknowledges that he has had and will continue to have a
          close, personal and special influence with Mannatech's customers and
          will be acquainted with all of Mannatech's business, particularly
          Mannatech's CONFIDENTIAL INFORMATION concerning the business of
          Mannatech and its affiliates.
     3.3  Robbins recognizes that his relationship with Mannatech is one of the
          highest trust and confidence by reason of Robbins's access to the
          CONFIDENTIAL INFORMATION and Robbins agrees to use his best efforts
          and will exercise utmost diligence to protect and safeguard the
          CONFIDENTIAL INFORMATION.
     3.4  Except as may be required by Mannatech or with the express written
          permission of Mannatech, Robbins shall not, either during his
          relationship with Mannatech or at any time thereafter, directly or

          Mannatech, use for his own benefit or for the benefit of another, or
          disclose to another, any CONFIDENTIAL INFORMATION of Mannatech, its
          customers, contractors, or any other person or entity with which
          Mannatech has a business relationship.
     3.5  Robbins agrees that all files, memoranda, data, notes, records,

          of which he has knowledge about or which he has acquired information.

          this provision will cause irreparable loss and harm to Mannatech which
          cannot be reasonably or adequately compensated by damages in an action

          bond or other security, to injunctive and other equitable relief to
          enforce the provisions of this section but no action for any such

          for damages.

          the event of his breach of certain provisions of this Agreement would
          be inadequate, and Robbins agrees that Mannatech, in addition to all
          other remedies it may have, shall have the right to injunctive relief
          if there is a breach by Robbins of any one or more of the provisions
          contained herein

          delivery service to the address as first written above.

     5.9  NO AGENCY. This Agreement does not constitute a joint venture or
          partnership of any kind between Mannatech and Robbins.

     5.10 WAIVER. A waiver by either party of any term or condition of this

          term or condition.

          solely for convenience of reference and are not intended and shall not

          constriction upon any of the provisions of this Agreement.

     5.13 GOVERNING LAW. The Parties hereto agree that this Agreement shall be
          governed by the laws of the State of Texas without regard to the
          conflicts of law principles. The Parties further agree that exclusive

          shall be in a state or federal court of appropriate jurisdiction in
          Dallas County, Texas. Each party consents to personal jurisdiction in
          Dallas County, Texas, for any action to enforce the Agreement
          including any further rules provided for emergency or extraordinary
          relief, as to this Agreement.

     5.14 DISCLOSURE. Each of the Parties agree to keep confidential the
          specific terms of this Agreement, and shall not disclose the terms of
          this Agreement to any person except the financial, tax and legal
          advisors of the other (and the Board of Directors of Mannatech) unless
          required to disclose the same to others by legal process, in which
          event the Party so ordered shall first give notice to the other Party
          and an opportunity to seek a protective order. This Agreement may be
          disclosed or appended as an exhibit to any securities filing required
          to be made by Mannatech. However, after having been so disclosed or
          appended, Robbins shall have no further duty of confidentiality
          concerning this Agreement, as set forth in this paragraph.

          of their choice with regard to this Settlement Agreement and Release.

     5.17 COUNTERPARTS. This Agreement may be executed in multiple counterparts,
          any one of which will be deemed an original, but all of which will
          constitute one and the same instrument.
