Ken Dahlberg Announces Limited Market Trade Date

Date: March 30, 2006

Chairman and CEO Ken Dahlberg today announced that the next limited market trade for the purchase and sale of SAIC stock will be June 30, 2006. Participants in the SAIC Retirement Plan also will be able to take distributions or exchange SAIC stock in their accounts in accordance with the terms of the Plan on June 30.

As in the past, Bull, Inc. will process limit orders for the purchase or sale of shares of SAIC stock in the limited market trade. Mellon Investor Services, LLC will record the purchase or sale of stock as the Company’s transfer agent. Stockholders who participate in the limited market trade will be able to view changes to their equity holdings account through the MellonOne web portal after the trade settlement date, and Mellon also will send an Investor Activity Report (IAR) to those stockholders.

The June 30 limited market trade will be completed according to the following schedule:
