Stock Option Repurchase Program

Earlier today, Avid announced a stock option repurchase program. This program will allow you to sell your vested and unvested outstanding options with exercise prices equal to or greater than $40.00 per share to Avid. The amount that we are offering to pay for the repurchase of each option is:

• $1.50 per share for options with exercise prices greater than or equal to $40.00 and less than $50.00 per share; and

• $1.00 per share for options with exercise prices of $50.00 per share or higher.

The program commenced on May 18, 2009 and is scheduled to end at 5:00 p.m. (Eastern Time), on Tuesday, June 16, 2009 (unless otherwise extended) and is subject to numerous terms and conditions, which are contained in the Schedule TO that we filed with the Securities and Exchange Commission today. A copy of the Schedule TO and the offering materials can also be found on the Avid intranet site at

http://tewk-epprod.global.avidww.com:54000/irj/portal/OptionProgram. We encourage you to review the Schedule TO, including its exhibits and other offering materials before deciding to participate in the program.

Your personal election form is included as part of this email. The personal election form includes specific information about your current outstanding employee stock options that are eligible for repurchase. If after reviewing the offering materials, you choose to participate in the program, you must complete and sign your election form and return it to the stock plan administrator before the offer expiration date of 5:00 p.m. (Eastern Time), on Tuesday, June 16, 2009 (unless otherwise extended).
