|Change of Control: |  | You will be offered an executive Retention Agreement under which you will be entitled to receive severance in a lump-sum amount equal to twelve (12) months base salary plus earned commission
and twelve (12) months medical COBRA coverage in the event you are terminated for a reason other than Cause within two (2) years of a Change of Control of the Company.

At Overland we strive to maintain a safe, drug-free work environment conducive to effective business operations.
We require that our personnel and operating practices be consistent with the highest standards of health and safety. To meet these objectives, Overland requires successful completion of a drug screen test as a condition of employment. Please contact
Human Resources and they will set up your appointment.

Your Overland benefits will be effective on the 1stday of the month following your start date. Overland is committed to making available
excellent benefit programs and family services that respond to the needs of our employees. We believe we offer a flexible and competitive package. You will meet with our Human Resources Department upon your arrival so that they can explain your new
benefits and sign you up for coverage.

The Immigration Reform and Control Act of 1986 requires employers to provide verification of a new employees
identity and employment eligibility on their first day of employment. It is necessary, therefore, that you complete the US Government and Employment Eligibility Verification Form (I-9) and provide documentation to verify your identity and employment
eligibility. In order to begin your employment with us, and as part of our normal process, please bring your I-9 documents with you on your first day of work.

We greatly look forward to having you join Overland and become a member of our team. However, we recognize that you retain the option, as does Overland, of ending your employment with Overland at any time, with or without notice and with or
without cause. As such, your employment with Overland is at-will and neither this letter nor any other oral or written representations may be considered a contract for any specific period of time.

As an Overland employee, you will be asked to continually support our vision by living up to our values of Respect, Innovation, Winning,
Customers, and Knowledge. You will learn more about Overland and our values during your new hire orientation and you can learn more prior to your start of employment by visiting our website: www.overlandstorage.com. Please feel free to
bring any questions you may have to that discussion.
