Mr. Dave Roberson

[address]

Dear Dave:

We are very pleased to offer you the opportunity to serve on the Board of
Directors of Quantum Corporation.

As a Member of the Board of Directors, and under the current Board compensation
program, your Board retainer will be $40,000 per annum, all of which will be
paid in cash. Additionally, as a member of the Audit Committee of the Board, you
will receive a cash retainer of $12,500 per annum. The retainers are generally
paid in quarterly installments. Quantum will also reimburse you for any travel
or incidental expenses associated with performing your duties as a Board member.

We will recommend to the Leadership and Compensation Committee that restricted
stock units (RSUs) with a total value of $125,000 be awarded to you. The number
of RSUs to be awarded will be determined at the time of grant based on the
company's closing stock price on the date of the Leadership and Compensation
Committee's approval, which typically occurs on the first day of every month.
Therefore, the number of RSUs to be awarded to you should be determined using
the closing stock price on June 1, 2011. Once the RSUs have been approved, you
will receive documentation from E*Trade, Quantum's Stock Administrator, within
two (2) months from your start date. If you remain a Board member, you will
continue to receive an annual stock grant thereafter. Details of the ongoing
annual stock program will be forthcoming and are subject to change. Lastly, we
are pleased to offer you the opportunity to participate in Quantum's Deferred
Compensation Program, details of which are enclosed in this packet.

To confirm your acceptance of our offer, please sign one copy of this letter,
complete the enclosed documents, and return them in the enclosed envelope.
Please note that your membership becomes official upon your acceptance, as the
Board of Directors' have already approved your appointment. Upon your
appointment, our General Counsel, Shawn Hall, will contact you to arrange a
Board of Directors' orientation.
