There are no arrangements or understandings between Mr. Biddiscombe and any other persons pursuant to which Mr. Biddiscombe was appointed an officer of the Company. Mr. Biddiscombe does not have any family relationship with any of the Company's directors or executive officers or any persons nominated or chosen by the Company to be a director or executive officer.

In connection with Mr. Biddiscombe's appointment, on September 29, 2014, the Company and Mr. Biddiscombe entered into an employment agreement (the "Agreement"), which provides that as Chief Financial Officer, Mr. Biddiscombe will receive an annual base salary of $360,000 and an annual target bonus opportunity of up to approximately 60% of his base salary. In addition, the Agreement provides that, subject to the approval of the Compensation Committee of the Company's Board of Directors, Mr. Biddiscombe will receive an award of stock options to purchase 250,000 shares of the Company's common stock and an award of 200,000 restricted stock units covering shares of the Company's common stock. The options will be scheduled to vest as to 25% of the shares on the first anniversary of the date Mr. Biddiscombe becomes Chief Financial Officer and thereafter, in ratable monthly installments for 36 months. The restricted stock units are scheduled to vest in four equal installments on the first four anniversaries of the date Mr. Biddiscombe becomes Chief Financial Officer. Vesting of the awards is subject to Mr. Biddiscombe's continued service with the Company through each relevant date.

• Payments of any bonus earned under the Company's Corporate Incentive Plan while he was an employee, even if he is not employed on the pay-out date; and
• Acceleration of Mr. Biddiscombe's equity compensation awards such that he will have received one full year of vesting from his initial vesting commencement date.

In the event that Mr. Biddiscombe's employment is terminated by the Company without cause (as such term is defined in the Agreement) on or after October 1, 2015 and he is in an Executive Vice President role, Mr. Biddiscombe will be entitled to the following benefits:

In order to receive any of the severance benefits under the Agreement, Mr. Biddiscombe will be required to execute a customary release of claims in favor of the Company.
