Explanation of Responses:

1. Represents a Restricted Stock Award for 20,000 shares of common stock that vests in two (2) annual installments with thirty-three and one-thirds percent (33.33%) vesting on 08/04/2009 and sixty-six and two-thirds percent (66.66%) vesting on 08/04/2010.

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. Lowe stock options to purchase an aggregate of 40,000 shares of common stock on 08/04/2008, of which options to purchase 19,907 shares are Incentive Stock Options and options to purchase 20,093 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."
