Mr. Bayer holds a bachelor’s degree in accounting from Miami University.

Mr. Bayer has no family relationships with any director or executive officer of the Company and has not been involved in any related person transactions that would require disclosure pursuant to Item 404(a) of Regulation S-K.

In connection with his appointment as the Company’s Senior Vice President, Controller and Chief Accounting Officer, Mr. Bayer has entered into an employment agreement with the Company, effective June 1, 2015. Mr. Bayer’s employment is terminable by either the Company or Mr. Bayer at any time, upon 30 days written notice.

Mr. Bayer is entitled to receive an annual base compensation, which may be adjusted annually at the discretion of the Company’s Compensation Committee, and options to purchase common stock and restricted stock in the Company pursuant to the terms and conditions set forth in the applicable award agreements and the Company’s 2013 Omnibus Stock Incentive Plan. Mr. Bayer will also be eligible to receive an annual performance bonus, with the amount to be determined by the Company’s Compensation Committee in its sole discretion based on achievement of objectives established by the Compensation Committee. Mr. Bayer is also eligible to participate in all normal Company benefits, including the Company’s 401(k), retirement, medical, dental and life and disability insurance plans and programs in accordance with the terms of such arrangements.

If Mr. Bayer’s employment is terminated by the Company without cause, Mr. Bayer will be entitled to (i) continuation of his base salary for 12 months following his termination, (ii) reimbursement for COBRA premiums due to maintain substantially equivalent health insurance coverage for 12 months following his termination, (iii) payment of any earned but unpaid salary and accrued but unused paid time off, (iv) payment of any business expenses incurred but not reimbursed, and (v) payment of an award under the annual bonus program that has been approved by the Chief Executive Officer and the Company’s board of directors, but not paid prior to termination. The payment of (i) and (ii) above shall be contingent on Mr. Bayer executing a separation agreement containing a general release of all claims against the Company.
