need not be identical) and, with the consent of the holder thereof, modify or amend each Option; (viii) to accelerate or defer (with the consent of the Optionee) the exercise date of any Option, consistent with the provisions of Section 5 of the
Plan; (ix) to authorize any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted by the Board; and (x) to administer and interpret the option agreement; (xi) to make
determinations as to whether a bona fide leave shall be deemed to continue, to the extent that applicable law does not require that it be deemed to continue; and (xii) to make all other determinations deemed necessary or advisable for the
administration of the Plan. 
  
 (c) Effect of
Board’s Decision. All decisions, determinations and interpretations of the Board shall be final and binding on all Optionees and any other holders of any Options granted under the Plan.

 (a) Incentive Stock Options may be granted only to
Employees. An Employee who has been granted an Option may, if such Employee is otherwise eligible, be granted an additional Option or Options. 
  
 (b) The Plan shall not confer upon any Optionee any right with respect to continuation of employment with the Company nor shall it
interfere in any way with Optionee’s right or the Company’s right to terminate Optionee’s employment at any time. 
  
 (c) No individual may receive Options under this Plan during any calendar year for more than 250,000 shares of the Company’s stock.

  
 6. Term of Plan. The Plan shall become effective upon
the earlier to occur of its adoption by the Board or its approval by the shareholders of the Company as described in Section 17 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 13 of the
Plan. 
  
 7. Term of Option. Each Option shall terminate
and is no longer exercisable after 5:00 p.m. on the day immediately preceding the ten (10) year anniversary of the date of its grant, except if terminated earlier as provided in the Stock Option Agreement. However, in the case of an Option granted
to an Optionee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from
the date of grant thereof or such shorter time as may be provided in the Stock Option Agreement. 
  
 8. Exercise Price and Consideration. 
  
 (a) The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the
Board, but shall be subject to the following: 
  
 (1) In the case of an Incentive Stock Option granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company
or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the fair market value per Share on the date of grant. 
  

 2 

 (2) In the case of an Incentive Stock Option granted to any other Employee, the per Share
exercise price shall be no less than 100% of the fair market value per Share on the date of grant. 
  
 (b) The fair market value per Share shall be determined as follows: (i) if the Common Stock is listed on a national securities exchange,
the closing sale price per share on the principal exchange on which the Common Stock is listed as reported by such exchange, (ii) if the Common Stock is quoted in the National Market System, the closing sale price per share as reported by NASDAQ,
(iii) if the Common Stock is traded in the over-the-counter market but not quoted in the National Market System, the average of the closing bid and asked quotations per share as reported by NASDAQ, or any other nationally accepted reporting medium
if NASDAQ quotations shall be unavailable, or (iv) if none of the foregoing applies, the fair market value of the Common Stock will be the fair value of the Common Stock as reasonably determined in the good faith judgment of the Board. 

 
 (c) An option may be exercised, in whole or in part, to
the extent exercisable, by giving written notice prior to its expiration to the Chief Financial Officer of the Company in the form specified by the Committee, accompanied by payment of the option price. In addition to the option price the Optionee
will be required to include payment of all federal, state, local or other income, excise or employment taxes subject to withholding (if any) by the Company, a parent or subsidiary as a result of the exercise of this option (collectively, the
“Exercise Price”) for the total number of shares specified for purchase. The Exercise Price payment shall be payable in full by cash or check. Alternatively, in the sole discretion of the Committee and upon such terms as the Committee
shall approve, the option may provide that the Exercise Price may be paid by: 
  
 (1) Cashless Exercise. During any period for which the shares are publicly traded (i.e., the shares are listed on any established stock exchange or a national market system, including without limitation the
NASDAQ National Market, or if the shares are quoted on the NASDAQ System (but not on the NASDAQ National Market) or any similar system whereby the stock is regularly quoted by a recognized securities dealer but closing sale prices are not reported),
by a copy of instructions to a broker directing such broker to sell the shares for which this option is exercised, and to remit to the Company the aggregate Exercise Price of such option (“Cashless Exercise”); provided, however, a Cashless
Exercise by a Director or executive officer that involves or may involve a direct or indirect extension of credit or arrangement of an extension of credit by the Company, a parent or subsidiary in violation of section 402(a) of the Sarbanes-Oxley
Act (codified as Section 13(k) of the Securities Exchange Act of 1934, 15 U.S.C. § 78m(k)) shall be prohibited; 
  
 (2) (unless prohibited by the Committee) certificates representing shares of Common Stock of the Company, which will be valued by the
Company at the closing fair market price per share of the Company’s Common Stock on the date of exercise of such certificates to the Company, accompanied by an assignment of the stock to the Company, provided that such shares have been held and
owned by the Optionee for at least six (6) prior months; or 
  
 (3) (unless prohibited by the Committee) any combination of cash and Common Stock of the Company valued and subject to the restrictions as provided in clause (2). Any assignment of stock shall be in a form and
substance satisfactory to the Secretary of the Company, including guarantees of signature(s) and payment of all transfer taxes if the Secretary deems such guarantees necessary or desirable. 
  
 (d) Under Section 422(d) of the Code, to the extent that the
aggregate fair market value of stock with respect to which incentive stock options are exercisable for the first time by the undersigned during any calendar year (under all incentive stock option plans of the Company, a parent or subsidiaries)
exceeds $100,000.00, such options shall be treated as options which are not incentive stock options, but shall be exercisable by their terms. Where more than one option that has been designated as an incentive stock option, the determination of
which options are to be treated as incentive stock options shall be based on the order in which such options were granted. If the $100,000 annual limitation is first exceeded as the result of the option covered by this agreement, upon each exercise
of this option, that fraction of shares of Common Stock covered by such exercise, equal to (i) the amount by which the grant of this option causes the $100,000 annual limitation to be exceeded, divided by (ii) the aggregate fair market value of this
option, determined as provided above, shall be treated as shares acquired upon exercise of options which are not incentive stock options, and the balance shall be treated as shares acquired upon exercise of an incentive stock option. 
  
 9. Exercise of Option. 
  
 (a) Procedure for Exercise; Rights as a Shareholder.
Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Board, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the
Plan. 
  

 3 

 An Option may not be exercised for a fraction of a Share. 
  
 An Option may be exercised in whole or in part prior to its
expiration at the time or times specified in the vesting schedule contained in the Stock Option Agreement. An Option shall be deemed to be exercised, in whole or in part, when written notice of such exercise has been given to the Chief Financial
Officer of the Company prior to its expiration, in accordance with the terms of the Option, by the person entitled to exercise the Option, and full payment (including any applicable withholding amounts) for the Shares with respect to which the
Option is exercised has been received by the Company. Full payment, as authorized by the Board, may consist of a consideration and method of payment allowable under Section 8(c) of the Plan. Until the issuance (as evidenced by the appropriate entry
on the books of the Company or of the duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned
Stock, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 11 of the Plan. Prior to the
time of issuance, the Company shall satisfy its employment tax and other tax withholding obligations by requiring the Optionee to pay the amount of withholding tax, if any, that must be paid under federal, state and local law due to the exercise of
the Option, subject to such restrictions or procedures as the Company deems necessary to satisfy Rule 16b-3 of the Exchange Act. The payment of such withholding tax may be by certified or official bank check or by the delivery of a number of shares
of Common Stock (plus cash if necessary) having a fair market value equal to the amount of such withholding tax. 
  
 Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for
purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
  
 (b) Termination of Status as an Employee. If any Employee ceases to serve as an Employee, such Employee may, but only within thirty
(30) days (or such other period of time not exceeding three (3) months as is determined by the Board at the time of grant of the Option) after the date such person ceases to be an Employee, exercise his or her Option to the extent that such person
was entitled to exercise it at the date of such termination. To the extent that such Employee was not entitled to exercise the Option at the date of such termination, or if such Employee does not exercise such Option (which such person was entitled
to exercise) within the time specified herein, the Option shall terminate. 
  
 An Employee who is employed by an employer that is a subsidiary of the Company, will be considered to have terminated Employee status in the event that the employer ceases to be a subsidiary of the Company.

  
 Service shall be deemed to continue while
Employee is on a bona fide leave of absence, to the extent required by applicable law. To the extent applicable law does not require such a leave to be deemed to continue while on a bona fide leave of absence, such bona fide leave of absence shall
be deemed to continue if, and only if, expressly provided in writing by the Committee or a duly authorized officer of the Company, parent or subsidiary for whom Employee provides services. 
  
 Outstanding options that are not exercisable at the time of
termination of service for any reason shall expire at the close of business on the date of such termination. 
  
 (c) Disability of Optionee. Notwithstanding the provisions of Section 9(b) above, in the event an Employee is unable to continue
his or her employment relationship with the Company as a result of such Employee’s total and permanent disability (as defined in Section 22(e)(3) of the Code), such Employee may, but only within six (6) months (or such other period of time not
exceeding twelve (12) months as is determined by the Board at the time of grant of the Option) from the date of termination, exercise his or her Option to the extent such person was entitled to exercise it at the date of such termination. To the
extent that the Employee was not entitled to exercise the Option at the date of termination, or if such Employee does not exercise such Option (which such person was entitled to exercise) within the time specified herein, the Option shall terminate.

  
 (d) Death of Optionee. In the event of
the death of an Optionee: 
  
 (1) during the term
of the Option who is at the time of his or her death an Employee and who shall have been in Continuous Status as an Employee since the date of grant of the Option, the Option may be exercised, at any time within six (6) months following the date of
death, by the Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that would have accrued had the Optionee continued living and remained in
Continuous Status as an Employee six (6) months after the date of death; or 
  

 4 

 (2) within thirty (30) days (or such other period of time not exceeding three (3) months
as is determined by the Board at the time of grant of the Option) after the termination of Continuous Status as an Employee, the Option may be exercised, at any time within six (6) months following the date of death, by the Optionee’s estate or
by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of termination. 
  
 10. Non-Transferability of Options. The Option may not be sold, pledged, assigned, hypothecated, transferred, or
disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. 
  
 11. Adjustments Upon Changes in Capitalization or Merger. Subject to any required action by the shareholders of the
Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of any Option, as well as the price per share of Common Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares
of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of Common Stock, recapitalization, or any other increase or decrease in the number of issued shares of Common Stock effected without
receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the
Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option. 
  
 In the event of the proposed dissolution or liquidation of the Company, the Option will terminate immediately prior to the consummation of such proposed
action, unless otherwise provided by the Board. The Board may, in the exercise of its sole discretion in such instances, declare that any Option shall terminate as of a date fixed by the Board and give each Optionee the right to exercise his or her
Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. In the event of the proposed sale of all or substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, the Option shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless the Board determines, in the exercise of its
sole discretion and in lieu of such assumption or substitution, that the Optionee shall have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. In the event
of any recapitalization, merger, consolidation, transfer of assets, reorganization, conversion or what the Committee deems in its sole discretion to be a similar transaction or circumstance, where the Company is not the surviving entity, if this
option is cancelled without substitution of a successor option or payment of alternative consideration that the Committee determines in good faith to be equitable under the circumstances, Optionee shall have the right, exercisable during the later
of the ten-day period ending on the fifth day prior to such transaction or ten days after the Committee provides Optionee with a notice of cancellation, to exercise this option in whole or in part without regard to any installment exercise
provisions in the Stock Option Agreement. 
  
 12. Time of
Granting Options. The date of grant of an Option shall, for all purposes, be the date on which the Board makes the determination granting such Option. Notice of the determination shall be given to each Employee to whom an Option is so granted
within a reasonable time after the date of such grant. 
  
 13.
Amendment and Termination of the Plan. 
  
 (a) Amendment and Termination. The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable; provided that, the following revisions or amendments shall require approval of the
shareholders of the Company in the manner described in Section 17 of the Plan: 
  
 (1) an increase in the number of Shares subject to the Plan above 1,000,000 Shares, other than in connection with an adjustment under
Section 11 of the Plan; 
  
 (2) any change in the
designation of the class of employees eligible to be granted options; or 
  
 (3) if the Company has a class of equity security registered under Section 12 of the Exchange Act at the time of such revision or amendment, any material amendment under the Plan. 
  
 (b) Shareholder Approval. If any amendment requiring
shareholder approval under Section 13(a) of the Plan is made subsequent to the first registration of any class of equity security by the Company under Section 12 of the Exchange Act, such shareholder approval shall be solicited as described in
Section 17 of the Plan. 
  

 5 

 (c) Effect of Amendment or Termination. Any such amendment or termination of the
Plan shall not affect Options already granted and such Options shall remain in full force and effect as if the Plan had not been amended or terminated, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in
writing and signed by the Optionee and the Company. 
  
 14.
Conditions Upon Issuance of Shares. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares pursuant thereto shall comply with all relevant provisions of
law, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, applicable state securities laws, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. 
  
 As a condition to the exercise of an Option, the Company may require the person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned
relevant provisions of law. 
  
 The Company may, but shall not be
obligated to, register or qualify the sale of shares under the Securities Act of 1933 or any other applicable law. The Company shall not be obligated to take any affirmative action in order to cause the sale of shares under this agreement to comply
with any law. 
  
 15. Reservation of Shares. The Company,
during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
  

Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 
  
 16. Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve. 
  
 17.
Shareholder Approval. Continuance of the Plan shall be subject to approval by the shareholders of the Company within twelve months before or after the date the Plan is adopted. If such shareholder approval is obtained at a duly held
shareholders meeting, it may be obtained by the affirmative vote of the holders of a majority of the outstanding shares of the Company, such holders being present or represented and entitled to vote thereon. 
  
 18. Information to Optionees. The Company shall provide to each Optionee, during the
period for which such Optionee has one or more Options outstanding, copies of all annual reports and other information which are provided to all shareholders of the Company. The Company shall not be required to provide such information if the
issuance of Options under the Plan is limited to key employees whose duties in connection with the Company assure their access to equivalent information. 
  
 19. CHOICE OF LAW. THE CORPORATE LAW OF THE STATE OF TEXAS WILL GOVERN ALL QUESTIONS CONCERNING THE RELATIVE RIGHTS OF THE COMPANY AND ITS
SHAREHOLDERS. ALL OTHER QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND INTERPRETATION OF THIS PLAN AND THE INSTRUMENTS EVIDENCING OPTIONS WILL BE GOVERNED BY THE INTERNAL LAW, AND NOT THE LAW OF CONFLICTS, OF THE STATE OF TEXAS. 

 
 IN WITNESS WHEREOF, the Company has caused its duly authorized officer to
execute this Plan effective as of the 7th day of August, 2003.

 EXHIBIT A 
  

Incentive Stock Option Agreement  
  
 MANNATECH, INCORPORATED 
  
 INCENTIVE STOCK OPTION AGREEMENT 
  
 Mannatech, Incorporated, a Texas corporation (the “Company”) has granted to (1) (the “Optionee”), an option to purchase a total of (2)
shares of Common Stock (the “Option”), at the price determined as provided herein, and in all respects subject to the terms, definitions and provisions of the Mannatech, Incorporated 1998 Restated and Amended Incentive Stock Option Plan,
as such may be amended from time to time (the “Plan”) adopted by the Company which is incorporated herein by reference. Capitalized terms used herein and not otherwise defined shall have the meanings assigned to them in the Plan.

  
 1. Nature of the Option. This Option is intended to
qualify as an Incentive Stock Option as defined in Section 422 of the Code. 
  
 2. Exercise Price. The exercise price is $ (3) for each share of Common Stock, which price is not less than the fair market value per share of the Common Stock on the Date of Grant (the “Exercise
Price”). 
  
 3. Exercise of Option. This Option shall
be exercisable during its term in accordance with the provisions of Section 9 of the Plan as follows: 
  
 (a) Right to Exercise. 
  
 (1) The Option granted hereunder shall not be exercisable in any part until the first anniversary of the Date of Grant (as hereinafter set
forth). The Option shall be exercisable as to (4) (        ) of the total shares covered by such Option as of the first anniversary of the Date of Grant. The right to exercise with respect to an
additional (4) (        ) of the total shares subject to the Option shall accrue on each of the (5), (5), (5) and (5) anniversaries of the Date of Grant and shall be cumulative. Notwithstanding the
foregoing, in the event of (A) a proposed sale of substantially all of the Common Stock of the Company, (B) a proposed sale of substantially all of the assets of the Company, (C) a proposed merger in which the Company is not to be the surviving
corporation (other than with a subsidiary of the Company) or (D) any other proposed extraordinary corporate transaction which, in the judgment of the Board, might deprive the Optionee of the full value of the Option granted hereunder, the Company
shall forward written notification of such transaction to the Optionee, and the Optionee shall have thirty (30) days in which to exercise all or any portion of the Option herein granted, including any portion of the Option which has not yet vested
as of such date (to the extent such Option has not been previously exercised), pursuant to the procedure set forth below. Upon the conclusion of such thirty-day period, unless otherwise determined by the Board, all rights of the Optionee hereunder
shall terminate. Any exercise of the Option by the Optionee shall be effective immediately prior to the occurrence of the transaction giving rise to the right to exercise the Option and, to the extent such transaction does not occur, the exercise
shall be deemed rescinded and the Optionee shall again only be entitled to exercise the Option according to the vesting schedule set forth above. 
  
 (2) This Option may not be exercised for a fraction of a share. 
  
 (3) In the event of the Optionee’s death, disability or other termination of employment, the
exercisability of the Option is governed by Sections 7, 8 and 9 below. 
  
 (b) Method of Exercise. This Option shall be exercisable by written notice to the Company which shall state the election to exercise the Option, the number of Shares in respect of which the Option is being
exercised, and such other representations and agreements as to the holder’s investment intent with respect to such shares of Common Stock as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be
signed by the Optionee and shall be delivered in person or by mail to the Chief Financial Officer of the Company. The written notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price. 
  
 No Shares will be issued pursuant to the exercise of an Option unless such issuance and such exercise shall comply with all relevant provisions of law and the requirements of any stock exchange upon which the Shares may then be listed and
the payment of withholding tax, if any, has been made in compliance with the terms of the Plan. Assuming such compliance, the Shares shall be considered transferred to the Optionee on the date determined pursuant to the provisions of the Plan.

 4. Optionee’s Representations. In the event the Shares purchasable pursuant to the exercise
of this Option have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, Optionee shall, concurrently with the exercise of all or any portion of this Option, deliver to the Company a Letter
Agreement in the form attached hereto as Exhibit A and such Optionee’s spouse shall execute the consent at the end of such Letter Agreement. 
  
 5. Method of Payment. Payment of the exercise price shall be by: 
  
 (a) cash; 
  
 (b) certified or official bank check; or 
  
 (c) surrender of other Shares of Common Stock of the Company of a value equal to the exercise price of the Shares as to which the Option
is being exercised. 
  
 6. Restrictions on Exercise. This

 9. Exercise of Option 
  
 (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be
exercisable at such times and under such conditions as determined by the Board, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan. 
  
 An Option may not be exercised for a fraction of a Share.

  
 An option may be exercised in whole or in
part prior to its expiration at the time or times specified in the vesting schedule contained in the Stock Option Agreement. An Option shall be deemed to be exercised, in whole or in part, when written notice of such exercise has been given to the
Chief Financial Officer of the Company prior to its expiration, in accordance with the terms of the Option, by the person entitled to exercise the Option, and full payment (including any applicable withholding amounts) for the Shares with respect to
which the Option is exercised has been received by the Company. Full payment, as authorized by the Board, may consist of a consideration and method of payment allowable under section 8(c) of the Plan. Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of the duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 11 of
the Plan. Prior to the tune of issuance, the Company shall satisfy its employment tax and other tax withholding obligations by requiring the Optionee to pay the amount of withholding tax, if any, that must be paid under federal, state and local law
due to the exercise of the Option, subject to such restrictions or procedures as the Company deems necessary to satisfy Rule 16b-3 of the Exchange Act. The payment of such withholding tax may be by certified or official bank check or by the delivery
of a number of shares of Common Stock (plus cash if necessary) having a fair market value equal to the amount of such withholding tax. 
  
 (b) Termination of Status as an Employee. If any Employee ceases to serve as an Employee, such Employee may, but only within thirty
(30) days (or such other period of time not exceeding three (3) months as is determined by the Board at the time of grant of the Option) after the date such person ceases to be an Employee, exercise Ms or her Option to the extent that such person
was entitled to exercise it at the date of such termination. To the extent that such Employee was not entitled to exercise the Option at the date of such termination, or if such Employee does not exercise such Option (which such person was entitled
to exercise) within the time specified herein, the Option shall terminate. 
  
 Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to
which the Option is exercised. 
  
 An Employee
who is employed by an employer that is a subsidiary of the Company, will be considered to have terminated Employee status in the event mat the employer ceases to be a subsidiary of the Company. 
  
 Service shall be deemed to continue while Employee is on a
bona fide leave of absence, to the extent required by applicable law. To the extent applicable law does not require such a leave to be deemed to continue while on a bona fide leave of absence, such bona fide leave of absence shall be deemed to
continue if, and only if, expressly provided in writing by the Committee or a duly authorized officer of the Company, parent or subsidiary for whom Employee provides services. 
  
 Outstanding options that are not exercisable at the time of termination of service for any reason shall
expire at the close of business on the date of such termination. 
  
 (c) Disability of Optionee. Notwithstanding the provisions of Section 9(b) above, in the event an Employee is unable to continue his or her employment relationship with the Company as a result of such
Employee’s total and permanent disability (as defined in Section 22(e)(3) of the Code), such Employee may, but only within six (6) months (or such other period of time not exceeding twelve (12) months as is determined by the. Board, at the time
of grant of the Option) from the date of termination, exercise his or her Option to the extent such person was entitled to exercise it at the date of such termination. To the extent that the Employee was not entitled to exercise the Option at the
date of termination, or if such Employee does not exercise such Option (which such person was entitled to exercise) within, the time specified herein, the Option shall terminate. 
  

 4 

 (d) Death of Optionee. In the event of the death of an Optionee: 
  
 (i) during the term of the Option who is at the time of his
or her death an Employee and who shall have been in Continuous Status as an Employee since the date of grant of the Option, the Option may be exercised, at any time within six (6) months following the date of death, by the Optionee’s estate or
by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that would have accrued had lie Optionee continued living and remained in Continuous Status as an Employee six (6)
months after the date of death; or 
  
 (ii)
within thirty (30) days (or such other period of time not exceeding three (3) months as is determined by the Board at the time of grant of the Option) after the termination of Continuous Status as an Employee, the Option may be exercised, at any
time within six (6) months following the date of death, by the Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the
date of termination. 
  
 10. Non-Transferability of
Options. The Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of hi any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the
Optionee.

Merger. Subject to any required action, by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan
but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of any Option, as well as the price per share of Common Stock covered by each such outstanding Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of Common Stock, recapitalization, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without
receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class,
or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option. 
  
 In the event of the proposed dissolution or liquidation of the Company, the
Option will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board. The Board may, in the exercise of its sole discretion in such instances, declare that any Option shall terminate as of a
date fixed by the Board and give each Optionee the right to exercise his or her Option as to all or any part of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. In the event of the proposed sale of all
or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, the Option shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of
such successor corporation, unless the Board determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the Optionee shall have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which the Option would not otherwise be exercisable. In the event of any recapitalization, merger, consolidation, transfer of assets, reorganization, conversion or what the Committee deems in its sole discretion to be a similar
transaction or circumstance, where the Company is not the surviving entity, if this option is cancelled without substitution of a successor option or payment of alternative consideration that the Committee determines in good faith to be equitable
under the circumstances, Optionee shall have the right, exercisable during the later of the ten-day period ending on the fifth day prior to such transaction or ten days after the Committee provides Optionee with a notice of cancellation, to exercise
this option in whole or in part without regard to any installment exercise provisions in the Stock Option Agreement. 
  
 12. Time of Granting Options. The date of grant of an Option shall, for all purposes, be the date on which the Board makes the determination
granting such Option. Notice of the determination shall be given to each Employee to whom an Option is so granted within a reasonable time after the date of such grant.

require the person exercising such Option to represent and warrant at the tune of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, hi the opinion of
counsel for the Company, such a representation is required by any of the aforementioned relevant provisions of law. 
  
 The Company may, but shall not be obligated to, register or qualify the sale of shares under the Securities Act of 1933 or any other
applicable law. The Company shall not be obligated to take any affirmative action in order to cause the sale of shares under this agreement to comply with any law. 
  
 15. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available
such number of Shares as shall be sufficient to satisfy the requirements of the Plan. Inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary
to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 
  
 16. Option Agreement. Options shall be evidenced by written option
agreements in such form as the Board shall approve. 
  
 17.
Shareholder Approval. Continuance of the Plan shall be subject to approval by the shareholders of the Company within twelve months before or after the date the Plan is adopted. If such shareholder approval is obtained at a duly held
shareholders meeting, it may be obtained by the affirmative vote of the holders of a majority of the outstanding shares of the Company, such holders being present or represented and entitled to vote thereon.

 18. Information to Optionees. The Company shall provide to each Optionee, during the period for
which such Optionee has one or more Options outstanding, copies of all annual reports and other information which are provided to all shareholders of the Company. The Company shall not be required to provide such information if the issuance of
Options under the Plan is limited to key employees whose duties in connection with the Company assure their access to equivalent information. 
  
 19. CHOICE OF LAW. THE CORPORATE LAW OF THE STATE OF TEXAS WILL GOVERN ALL QUESTIONS CONCERNING THE RELATIVE RIGHTS OF THE COMPANY AND ITS
SHAREHOLDERS. ALL OTHER QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND INTERPRETATION OF THIS PLAN AND THE INSTRUMENTS EVTOENCING OPTIONS WILL BE GOVERNED BY THE INTERNAL LAW, AND NOT THE LAW OF CONFLICTS, OF THE STATE OF TEXAS. 

 
 IN WITNESS WHEREOF, the Company has caused its duly authorized officer to
execute this Plan effective as of the 7th day of August, 2003.

 EXHIBIT A 
  

Incentive Stock Option Agreement 
  
 MANNATECH, INCORPORATED 
  
 INCENTIVE STOCK OPTION AGREEMENT 
  
 Mannatech, Incorporated, a Texas corporation (the “Company”) has granted to (1) (the “Optionee”), an option to purchase a total of (2)
shares of Common Stock (the “Option”), at the price determined as provided herein, and in all respects subject to the terms, definitions and provisions of the Mannatech, Incorporated 2000 Restated and Amended Incentive Stock Option Plan,
as such may be amended from time to time (the “Plan”) adopted by the Company which is incorporated herein by reference. Capitalized terms used herein and not otherwise defined shall have the meanings assigned to them in the Plan.

  
 1. Nature of the Option. This Option is intended to
qualify as an Incentive Stock Option as defined in Section 422 of the Code. 
  
 2. Exercise Price. The exercise price is $ (3) for each share of Common Stock, which price is not less than the fair market value per share of the Common Stock on the Date of Grant (the “Exercise
Price”). 
  
 3. Exercise of Option. This Option shall
be exercisable during its term in accordance with the provisions of Section 9 of the Plan as follows: 
  
 (a) Right to Exercise. 
  
 (1) The Option granted hereunder shall not be exercisable in any part until the first anniversary of the Date of Grant (as hereinafter set
forth). The Option shall be exercisable as to (4) ( ) of the total shares covered by such Option as of the first anniversary of the Date of Grant. The right to exercise with respect to an additional (4) ( ) of the total shares subject to the Option
shall accrue on each of the (5), (5), (5) and (5) anniversaries of the Date of Grant and shall be cumulative. Notwithstanding the foregoing, in the event of (A) a proposed sale of substantially all of the Common Stock of the Company, (B) a proposed
sale of substantially all of the assets of the Company, (C) a proposed merger in which the Company is not to be the surviving corporation (other than with a subsidiary of the Company) or (D) any other proposed extraordinary corporate transaction
which, in the judgment of the Board, might deprive the Optionee of the full value of the Option granted hereunder, the Company shall forward written notification of such transaction to the Optionee, and the Optionee shall have thirty (30) days in
which to exercise all or any portion of the Option herein granted, including any portion of the Option which has not yet vested as of such date (to the extent such Option has not been previously exercised), pursuant to the procedure set forth below.
Upon the conclusion of such thirty-day period, unless otherwise determined by the Board, all rights of the Optionee hereunder shall terminate. Any exercise of the Option by the Optionee shall be effective immediately prior to the occurrence of the
transaction giving rise to the right to exercise the Option and, to the extent such transaction does not occur, the exercise shall be deemed rescinded and the Optionee shall again only be entitled to exercise the Option according to the vesting
schedule set forth above. 
  
 (2) This Option may
not be exercised for a fraction of a share. 
  
 (3) In the event of the Optionee’s death, disability or other termination of employment, the exercisability of the Option is governed by Sections 7, 8 and 9 below. 
  
 (b) Method of Exercise. This Option shall be exercisable by written notice to the Company which shall
state the election to exercise the Option, the number of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such shares of Common Stock as
may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by the Optionee and shall be delivered in person or by mail to the Chief Financial Officer of the Company. The written notice shall be
accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price. 
  
 No Shares will be issued pursuant to the exercise of an Option unless such issuance and such exercise shall
comply with all relevant provisions of law and the requirements of any stock exchange upon which the Shares may then be listed and the payment of withholding tax, if any, has been made in compliance with the terms of the Plan. Assuming such
compliance, the Shares shall be considered transferred to the Optionee on the date determined pursuant to the provisions of the Plan. 
  

 8 

 4. Optionee’s Representations. In the event the Shares purchasable pursuant to the exercise
of this Option have not been registered under the Securities Act of 1933, as amended, at the time this Option is exercised, Optionee shall, concurrently with the exercise of all or any portion of this Option, deliver to the Company a Letter
Agreement in the form attached hereto as Exhibit A and such Optionee’s spouse shall execute the consent at the end of such Letter Agreement. 
  
 5. Method of Payment. Payment of the exercise price shall be by: 
  
 (a) cash; 
  
 (b) certified or official bank check; or 
  
 (c) surrender of other Shares of Common Stock of the Company of a value equal to the exercise price of the Shares as to which the Option
is being exercised. 
  
 6. Restrictions on Exercise. This
Option may not be exercised until such time as the Plan has been approved by the shareholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute violation
of any applicable federal or state securities or other law or regulation, including any rule under Part 207 of Title 12 of the Code of Federal Regulations (“Regulation G”) as promulgated by the Federal Reserve Board. As a condition to the
exercise of this Option, the Company may require Optionee to make any representation and warranty to the Company as may be required by any applicable law or regulation. 
  
 7. Termination of Status as an Employee. If Optionee ceases to serve as an Employee, Optionee may, but only within
(6) days after the date Optionee ceases to be an employee of the Company, exercise this Option to the extent that Optionee was entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise this
Option at the date of such termination, or if Optionee does not exercise this Option within the time specified herein, the Option shall terminate. 
  
 8. Disability of Optionee. Notwithstanding the provisions of Section? above, if Optionee is unable to continue his or her employment with the
Company as a result of his or her total and permanent disability (as defined in Section 22(e) (3) of the Code), Optionee may, within (7) months from the date of termination of employment, exercise his or her Option to the extent Optionee was
entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option (which Optionee was entitled to exercise) within
the time specified herein, the Option shall terminate. 
  
 9.
Death of Optionee. In the event of the death of Optionee: 
  
 (a) During the term of this Option and while an Employee of the Company and having been in Continuous Status as an Employee since the Date of Grant of the Option, the Option may be exercised, at any time within six
(6) months following the date of death, by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that would have accrued had the Optionee
continued living and remained in Continuous Status as an Employee six (6) months after the date of death; or 
  
 (b) within (8) days after the termination of Optionee’s Continuous Status as an employee, the Option may be exercised, at any time
within six (6) months following the date of death, by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to exercise that had accrued at the date of
termination. 
  
 10. Non-Transferability of Option. This
Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by such Optionee. The terms of this Option shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee. 
  
 11. Term of Option. This Option may not be exercised more than ten (10) years (five years if Optionee owns, immediately before this Option is granted, stock representing more than 10 percent of the total combined voting power of all
classes of stock of the Company or of any Parent or Subsidiary) from the date of grant of this Option, and may be exercised during such term only in accordance with the Plan and the terms of this Option.

extent necessary to render it legal, valid and enforceable, and if no such modification shall render it legal, valid and enforceable, then this Agreement shall be construed as if not containing the provision held to be invalid, and the rights and
