The 2013 Equity Plan permits the grant of awards with respect to an aggregate of 3,250,000 shares of common stock, with the maximum aggregate number of shares available for issuance in settlement of full value awards (i.e., awards other than options and stock appreciation rights) of 1,250,000 and the maximum aggregate number of shares available for issuance in settlement of options and stock appreciation rights of 2,000,000. The maximum number of shares that may be issued pursuant to incentive stock options is 2,000,000, and the maximum number of shares that may be made subject to awards granted in a calendar year to an individual participant is 1,250,000.
