The foregoing sentence does not change the at‐will nature of your employment and the Company may terminate you at any time, subject to the paragraph above titled “Severance.” While we look forward to a long and profitable relationship, you will be an at‐will employee of the Company, which means the employment relationship can be terminated by either party for any reason, at any time, with or without prior notice and with or without cause, subject to the paragraph above titled “Severance.“ Any statements or representations to the contrary (and, indeed, any statements contradicting any provision in this letter) should be regarded by you as ineffective. Further, your participation in any stock, option or benefit program is not to be regarded as assuring you of continuing employment for any particular period of time. Any modification or change in your at‐will employment status may only occur by way of a written employment agreement signed by you and the Chief Executive Officer of the Company.

Please note that because of employer regulations adopted in the Immigration Reform and Control Act of 1986, within three (3) business days of starting your new position you will need to present documentation demonstrating that you have authorization to work in the United States.
