         to the contrary, prior to July 1, 2004, a Participant may elect to
         receive an in-kind distribution of the fair market value of his or her
         Separate Account in the form of shares of Network Associates, Inc.
         common stock and cash, to the extent that the Separate Account is
         invested in the NAI Unitized Stock Fund at the time of distribution."

4.       Effective as of January 1, 2003, Section 11.2 is amended in its
         entirety to read as follows:

         Senior Vice President Corporate Controller, Vice President of Human
         Resources, and Benefits Analyst. The appointment of any person to such
         position shall automatically constitute the appointment of such person
         to the Administrative Committee and the resignation, termination or
         transfer of any person from such position shall constitute the
         automatic resignation of such person from the Administrative Committee.
