GNPX 2018 Proxy Statement

36 Corporate Transactions . In the event of a change in control, unless otherwise provided in a stock award or other written agreement between us and the holder of a stock award, each stock award will be treated as the plan administrator determines, arranging for the assumption or substitution of a stock award by a successor entity. If the successor entity does not assume or substitute for the stock award, the vesting and exercisability, if applicable, of the stock award will accelerate in full. Our plan administrator is not obligated to treat all stock awards or portions thereof or all holders of stock awards, even those that are of the same type, in the same manner. Under the 2009 Plan, a change in control is generally the occurrence of (1) any transaction or series of related transactions in which in excess of 50% of our voting power is transferred; (2) the replacement of a majority of the members of our Board during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of our Board prior to the date of such appointment or election; or (3) the acquisition by a third party of our assets that have a total gross fair market value equal to or more than 50% of the total gross fair market value of all of our assets immediately prior to such acquisition. Change in Control . The plan administrator may provide, in an individual award agreement or in any other written agreement between a participant and us that the stock award will be subject to additional acceleration of vesting and exercisability in the event of a change in control. Amendment and Termination . Our Board has the authority to amend, alter, suspend, or terminate our 2009 Plan, provided that such action does not impair the existing rights of any participant without such participant’s written consent. 2018 Employee Stock Purchase Plan The 2018 Employee Stock Purchase Plan, or ESPP, will become effective when the Board determines to make this benefit available to employees. The purpose of the ESPP is to retain the services of new employees and secure the services of new and existing employees while providing incentives for such individuals to exert maximum efforts toward our success and that of our affiliates. Share Reserve . The ESPP authorizes the issuance of 208,050 shares of our common stock pursuant to purchase rights granted to our employees or to employees of any of our designated affiliates. The number of shares of our common stock reserved for issuance will automatically increase on January 1 of each calendar year, beginning on January 1, 2019 and continuing through and including January 1, 2028 by 2% of the total number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by our Board. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code. As of the date hereof, no shares of our common stock have been purchased under the ESPP. Administration . Our Board has delegated its authority to administer the ESPP to our Compensation Committee. The ESPP is implemented through a series of offerings of purchase rights to eligible employees. Under the ESPP, we may specify offerings with durations of not more than 27 months, and may specify shorter purchase periods within each offering. Each offering will have one or more purchase dates on which shares of our common stock will be purchased for employees participating in the offering. An offering may be terminated under certain circumstances. Payroll Deductions . Generally, all regular employees, including executive officers, employed by us or by any of our designated affiliates, may participate in the ESPP and may contribute, normally through payroll deductions, up to 15% of their earnings for the purchase of our common stock under the ESPP. Unless otherwise determined by our Board, common stock will be purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (a) 85% of the fair market value of a share of our common stock on the first date of an offering or (b) 85% of the fair market value of a share of our common stock on the date of purchase. Limitations . Employees may have to satisfy one or more of the following service requirements before participating in the ESPP, as determined by our Board: (a) customarily employed for more than 20 hours per week,
