(2)	For purposes of clarity, this report restates (in its entirety) the report previously filed on 08/06/2008 to correct an error in footnote 2 regarding the option fully vested date contained in the originally filed Form 4. Footnote 2 is amended to read as follows, "Adaptec granted Mr. Westfield stock options to purchase an aggregate of 32,000 shares of common stock on 08/04/2008, of which options to purchase 23,481 shares are Incentive Stock Options and options to purchase 8,519 are Non-Qualified Stock Options. All of these options vest with respect to 8.33% of the total underlying shares at the end of each three-month period, such that the options will be fully vested on 08/04/2011. The options will expire on 08/04/2015."
