STOCK-BASED COMPENSATION

The Company currently has one active stock-based compensation plan, the Mannatech, Incorporated 2017 Stock Incentive Plan (the "2017 Plan"), which was adopted by the Company’s Board of Directors (the "Board") on April 17, 2017 and was approved by its shareholders on June 8, 2017. The 2017 Plan supersedes the Mannatech, Incorporated 2008 Stock Incentive Plan (the "2008 Plan"), as amended, which was set to expire on February 20, 2018. The Board has reserved a maximum of 250,000 shares of our common stock that may be issued under the 2017 Plan, consisting of 181,674 newly reserved shares and 68,326 shares that remained available for issuance under the 2008 Plan (subject to adjustments for stock splits, stock dividends or other changes in corporate capitalization). As of March 31, 2019, the Company had a total of 42,434 shares available for grant under the 2017 Plan, which expires on April 16, 2027.

The 2017 Plan provides for grants of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock and performance stock units to our employees, board members, and consultants. However, only employees of the Company and its corporate subsidiaries are eligible to receive incentive stock options. The exercise price per share for all stock options will be no less than the market value of a share of common stock on the date of grant. Any incentive stock option granted to an employee owning more than 10% of our common stock will have an exercise price of no less than 110% of our common stock’s market value on the grant date.

The majority of stock options vest over two or three years, and generally are granted with a term of ten years, or five years in the case of an incentive option granted to an employee who owns more than 10% of our common stock.
