The terms of this offer of employment are as follows:

1. At-Will Employment. You should be aware that your employment with the Company is for no specified period and constitutes “at-will” employment. As a result, you are free to terminate your employment at any time, for any reason or for no reason. Similarly, the Company is free to terminate your employment at any time, for any reason or for no reason.

Key Executive Bonus Plan: In addition to your base salary, you will be eligible to participate in an annual Key Executive Bonus Plan (effective May 1, 2013 for FY’14) to be adopted each fiscal year that sets your targeted bonus amount to be paid upon achievement of defined goals for the company and you. In your initial year of employment, your targeted annual bonus will be $224,000 at 100% achievement, pro-rated from your date of hire.

Moreover, you agree that, during the term of your employment with the Company, you will not engage in any other employment, occupation, consulting or other business activity directly related to the business in which the Company is now involved or becomes involved during the term of your employment, nor will you engage in any other activities that conflict with your obligations to the Company.

10. General. This offer letter, the Termination Upon Change of Control, EPIA, the Stock Option Agreement and the Restricted Stock Unit Award Agreement covering the shares described in paragraph 4, when signed by you, set forth the terms of your employment with the Company and supersede any and all prior representations and agreements, whether written or oral. In the event of a conflict between the terms and provisions of this offer letter, on the one hand, and the Termination Upon Change of Control, EPIA, the Stock Option

Austin, Gene - President

Agreement and the Restricted Stock Unit Award Agreement, on the other hand, the terms and provisions of the Termination Upon Change of Control, EPIA, the Stock Option Agreement and the Restricted Stock Unit Award Agreement will control.

It is the intent of this letter that all payment and benefits hereunder comply with or be exempt from the requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and the final regulations and any guidance promulgated thereunder and any applicable state law requirements (“Section 409A”) so that none of the payments and benefits to be provided under this letter will be subject to the additional tax imposed under Section 409A, and any ambiguities or ambiguous terms herein will be interpreted to be exempt or so comply. Each payment and benefit payable under this letter is intended to constitute a separate payment for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. You and the Company agree to work together in good faith to consider amendments to this letter and to take such reasonable actions which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under Section 409A.

Austin, Gene - President

Notwithstanding anything herein to the contrary, the reimbursement of expenses or in-kind benefits provided pursuant to this letter agreement shall be subject to the following conditions: (1) the expenses eligible for reimbursement or in-kind benefits in one taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits in any other taxable year; (2) the reimbursement of eligible expenses or in-kind benefits shall be made the earliest of (i) the date called for under Company’s applicable policies, (ii) the time provided by this Agreement, and (iii) the end of the year after the year in which such expense was incurred; and (3) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit.

We look forward to you joining the Company. If the foregoing terms are agreeable, please indicate your acceptance by signing this offer letter in the space provided below and returning it to me not later than April 19, 2013.
