MANNATECH, INCORPORATED 600 S. Royal Lane, Suite 200 Coppell, Texas 75019 ------------------------------------------ DEFINITIVE INFORMATION STATEMENT ------------------------------------------ WE ARE NOT ASKING YOU FOR A PROXY, AND YOU ARE REQUESTED NOT TO SEND US A PROXY. GENERAL This Information Statement is being furnished to the shareholders of Mannatech, Incorporated, a Texas corporation (the "Company"), in connection with the adoption by written consent of certain amendments to the Company's Second Amended and Restated Bylaws (the "Bylaws") by the written consent of the holders of a majority of the Company's common stock. On October 20, 1999 certain shareholders, including the principal shareholders of the Company's common stock, par value $0.0001 per share (the "Common Stock"), entered into discussions regarding the corporate governance of the Company. Certain amendments to the Bylaws were considered by these shareholders and adopted by a majority written consent of these shareholders (the "Consent") effective as of October 20, 1999. On November 1, 1999 the three principal shareholders of the Company executed three identical written consents (collectively, the "Further Consents" and collectively with the Consent, the "Consents") amending the Bylaws and restoring certain of the provisions of the Bylaws respecting the duties of the Chairman and the conduct of meetings to their prior content. The Further Consents were effective as of October 20, 1999. The net result of the changes to the Bylaws contained in the Consents was to provide: (i) that the Company's shareholders may set the number of directors of the Board of Directors (the "Board"); (ii) that the Board would be expanded from five members to seven; (iii) for revised procedures for the call, notice and administration of meetings of the Board; (iv) for revised duties of the Chairman of the Board respecting such Board meetings; and (v) for revised procedures for amending certain Bylaws provisions adopted by the Company's shareholders. The Consent also appointed a new director to fill one of the additional Board positions created by the Consents. If the amendments to the Bylaws had not been adopted by written consent, they would have been required to be considered by the Company's shareholders at a special shareholders' meeting convened for the specific purpose of approving the amendments. A special meeting of shareholders is not required to approve the amendments under Article Eleven of the Company's Amended and Restated Articles of Incorporation and Article 9A of the Texas Business Corporation Act (the "TBCA"), both of which provide that the written consent of the holders of outstanding shares of voting capital stock, having not less than the minimum number of votes which would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted, may be substituted for such a special meeting. The date on which this Information Statement was first sent to the shareholders is on or about May 1, 2000. No record date has been established by the Company for purposes of determining the number of outstanding

shares of voting capital stock of the Company in connection with the matters described herein as the action was taken via the Consents. Pursuant to Article 9.10A(4) of the TBCA, the Company is required to provide prompt notice of the taking of the corporate action without a meeting to shareholders who have consented in writing to such action. No dissenters' rights under the TBCA are afforded to the Company's shareholders as a result of the adoption of the amendments to the Bylaws. OUTSTANDING VOTING STOCK OF THE COMPANY As of October 20, 1999, there were 24,640,093 shares of Common Stock outstanding. The Common Stock constitutes the sole class of voting securities of the Company. Each share of Common Stock entitles the holder thereof to one vote on all matters submitted to shareholders. 2
