Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Option, when granted, vested as to (i) 25% on each of the first and second anniversary of the date of grant; (ii) 20% on each of the third and fourth anniversary of the date of grant; and (iii) 10% on the fifth anniversary of the date of grant. Effective August 2, 2004 (the date of the closing of the acquisition of Modus Media, Inc. by the issuer), one-third of the number of shares subject to the option that was not then vested became vested and exercisable. The number of shares subject to the option that will vest and become exercisable on each anniversary of the date of grant after August 2, 2004 will now be the number of shares that would otherwise have vested in accordance with the above-stated schedule, reduced by one-third. The shares subject to the option that are or become vested on or after August 2, 2004 shall be exercisable once vested.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
