Equity Incentive Awards

Our 2014 Equity Incentive Plan (the “2014 Plan”) was adopted by our Board of Directors on March 11, 2014 and approved by our stockholders on May 13, 2014. Pursuant to the 2014 Plan, our officers, directors, employees and consultants may be awarded (i) shares of common stock (“Restricted Stock Grants”), (ii) options to acquire shares of common stock (“Options”), including non-qualified stock options and incentive stock options within the meaning of Section 422 of the Internal Revenue Code, and (iii) other forms of equity awards subject to conditions and restrictions determined by the Compensation, Nominating, and Corporate Governance Committee of our Board of Directors (the “Compensation Committee”). The Compensation Committee will determine the vesting schedule, if any, of each Restricted Stock Grant or Option and the term of each Option, which term shall not exceed ten years from the date of grant. Shares that do not vest are forfeited. Dividends paid on restricted stock are not returnable, even if the underlying stock does not entirely vest. Options are awarded at the New York Stock Exchange closing price of our common stock on the grant date. A maximum of 3,750,000 shares of common stock are available for grant under the 2014 Plan. As of December 31, 2014, 3,563,334 shares remained available for grant.

Grants under the 2014 Plan are made by the Compensation Committee, which determines the individuals eligible to receive awards, the types of awards, and the terms, conditions and restrictions applicable to any award.
