Common Stock
"), reserved under the Mannatech, Incorporated 2008 Stock Incentive Plan, as amended effective May 28, 2014 (the "2008 Plan").  In addition, pursuant to Rule 416 promulgated under the Securities Act of 1933, as amended (the "
Securities Act
"), this Registration Statement also covers an indeterminate number of additional shares of Common Stock that may become issuable under the 2008 Plan to prevent dilution that may result from any future stock splits, stock dividends or similar transactions affecting the common stock.
(2)
Pursuant to Rules 457(c) and 457(h) promulgated under the Securities Act, the proposed maximum offering price is estimated, solely for the purpose of determining the registration fee, on the basis of the average of the high and low prices of the common stock on The Nasdaq Global Select Market on July 7, 2014, which is a date within five business days prior to the date of this Registration Statement.
EXPLANATORY NOTE
This Registration Statement on Form S-8 (the "
Registration Statement
") registers additional securities of the same class as other securities for which a registration statement on Form S-8 relating to an employee benefit plan is effective. This Registration Statement is being filed to register an additional 130,000 shares of common stock, par value $0.0001 per share (the "
Common Stock
"), of Mannatech, Incorporated (the "
Company
") available for issuance under the Mannatech, Incorporated 2008 Stock Incentive Plan, as amended (the "
2008 Plan
").  As a result of an amendment to the 2008 Plan, which was approved by our shareholders on May 28, 2014, the number of shares of Common Stock authorized for issuance under the 2008 Plan was increased by 130,000, thereby increasing the total number shares reserved for issuance under the 2008 Plan from 270,923 to 400,923.  The Common Stock registered under this Registration Statement is in addition to the shares of Common Stock registered on the Company's Form S-8 filed with the Securities and Exchange Commission (the "
Commission
") on August 26, 2008 (File No. 333-153199) (the "
Initial Registration Statement
") and the shares of Common Stock registered on the Company's Form S-8 filed with the Commission on July 16, 2012 (File No. 333-182676) (the "
Second Registration Statement
" and , together with the Initial Registration Statement, the "
Prior Registration Statements
").  The total number of shares issuable under the 2008 Plan includes shares subject to awards granted under our 2000 Stock Option Plan (the "
Prior Plan
"), which was replaced by the 2008 Plan, that were outstanding on the effective date of the 2008 Plan and that were subsequently terminated or forfeited, or that expired by their terms and thereafter returned to the pool of shares available for grant and issuance under the 2008 Plan.
In accordance with General Instruction E to Form S-8, the Company incorporates by reference the contents of the Company's Prior Registration Statements.
PART I
The Company will provide all participants in the 2008 Plan with the document(s) containing information required by Part I of Form S-8, as specified in Rule 428(b)(1) promulgated by the Commission under the Securities Act of 1933, as amended (the "

"). In accordance with the note to Part I of Form S-8 and Rule 428 of the Securities Act, the Company is not filing such document(s) with the Commission, but such documents (along with the documents incorporated by reference into this Registration Statement pursuant to Item 3 of Part II hereof) shall constitute a prospectus that meets the requirements of Section 10(a) of the Securities Act.

Item 6.
Indemnification of Officers and Directors
The following summary is qualified in its entirety by reference to the Texas Business Organizations Code (the "
TBOC
") and the Company's Amended and Restated Articles of Incorporation, as amended by that certain Certificate of Amendment to the Amended and Restated Articles of Incorporation, and Fourth Amended and Restated Bylaws, as amended by that certain First Amendment to Fourth Amended and Restated Bylaws, each of which contain provisions for indemnification of the Company's directors and officers.
Texas Law
Chapter 8 of the TBOC provides generally that a person sued as a director, officer, employee, agent or delegate of a corporation, may be indemnified by the corporation against judgments and reasonable expenses in connection with such proceeding if it is determined that such person has conducted himself in good faith and reasonably believed, in the case of conduct in his official capacity, that his conduct was in the corporation's best interests, and in any other case, that his conduct was not opposed to the corporation's best interests and, in the case of a criminal proceeding, that such person did not have a reasonable cause to believe his conduct was unlawful. The TBOC provides that a corporation may advance expenses incurred by a director in defending a suit or other similar proceeding. A Texas corporation is also permitted to indemnify and advance expenses to officers, employees and agents who are not directors to such extent as may be provided by its articles of incorporation, bylaws, action of board of directors, a contract or as provided by common law. Indemnification of a person found liable to the corporation or found liable because the person improperly received a personal benefit is limited to reasonable expenses actually incurred by the person in connection with the proceeding and may not be made if the person is found liable for (i) willful or intentional misconduct in the performance of the person's duty to the corporation, (ii) breach of the person's duty of loyalty owed to the corporation or (iii) an act or omission not committed in good faith that constitutes a breach of a duty owed by the person to the corporation. Indemnification is mandatory, however, in the case of such person being wholly successful, on the merits or otherwise, in the defense of the proceeding.
Chapter 8 of the TBOC also authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, agent or delegate of the corporation against any liability asserted against him and incurred by him in such a capacity or arising out of his status as such, whether or not the corporation would have the power to indemnify him against that liability under Chapter 8.
Bylaws and Articles of Incorporation
The Company's articles of incorporation and bylaws provide for indemnification of its officers and directors to the fullest extent permitted by the TBOC. In addition, the Company's articles of incorporation provide that a Company director shall not be liable to the Company or its shareholders for monetary damages for an act or omission in a director's capacity as a director of the Company.
The right to indemnification conferred by the Company's bylaws includes the right to be paid or reimbursed by the Company for expenses incurred in defending or otherwise participating in any proceeding of the type eligible for indemnification in advance of such proceeding's final disposition, provided, however, that any such advancement of expenses incurred by an officer or director of the Company will be made only upon delivery to the Company of a written affirmation, by or on behalf of such officer or director, of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification under the Company's bylaws and a written undertaking to repay all amounts so advanced if it is ultimately determined that such person is not entitled to be indemnified for such expenses under the Company's bylaws or otherwise. The Company will pay or reimburse expenses incurred by a director or officer in connection with his or her appearance as a witness or other participation in a proceeding at a time when he or she is not a named defendant or respondent in the proceeding.
The rights to indemnification provided by the Company's bylaws and articles of incorporation will not be deemed exclusive of any other rights which any person entitled to indemnification by the Company's bylaws or articles of incorporation may have or hereafter acquire under law (common or statutory), the Company's articles of incorporation, the Company's bylaws, an agreement, vote of stockholders or disinterested directors or otherwise.
Any repeal or amendment of provisions of the Company's bylaws or articles of incorporation affecting indemnification rights, whether by the Company's stockholders or by changes in applicable law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, and will not in any way diminish or adversely affect any indemnification right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.
2
Pursuant to the Company's bylaws, the Company may purchase and maintain insurance, to the extent permitted by the TBOC, to protect itself and any person who is or was serving as a director, officer, employee or agent of the Company or is or was serving at the request of the Company as a director, officer, partner, trustee, employee or agent of another corporation, partnership, trust or other enterprise against any expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the Company's bylaws.
Indemnification Agreements
The Company has entered into individual indemnification agreements with each of its directors that contractually obligate the Company to indemnify each director from and against any and all expenses actually and
reasonably incurred by the director in connection with any threatened, pending or completed action, suit or proceeding in which the director was made a party by reason of the fact that the director is or was a director of the Company to the fullest extent authorized and permitted by the provisions of the TBOC and the Company's bylaws and articles of incorporation, or by any amendment thereof.
The individual indemnification agreements with each of the Company's directors also provide that, to the extent that the Company maintains one or more insurance policy or policies providing directors' and officers' liability insurance, each director will be covered by such policy or policies in accordance with the terms of such policy or policies, to the maximum extent of the coverage applicable to any director then serving the Company.

Item 9.
Undertakings.
(a)
The undersigned registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement.  Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement;
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
Provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the registration statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
(2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b)
The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
(c)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
