BEA RESCHEDULES ANNUAL MEETING OF SHAREHOLDERS

TO MARCH 18, 2008

SAN JOSE, Calif. – December 20, 2007 – BEA Systems, Inc., a world leader in enterprise infrastructure software, today announced the rescheduling of its 2007 annual meeting of shareholders to March 18, 2008 from February 14, 2008. BEA’s Board of Directors believes it is in the best interest of shareholders to postpone the meeting until after BEA has reported financial results for the fourth quarter and fiscal year ending January 31, 2008.

Shareholders of record as of January 22, 2008 will be entitled to vote at the annual meeting. In connection with the new meeting date, BEA has extended the deadline for shareholders to propose director nominees and to bring proposals at the meeting to March 7, 2008.

BEA’s largest shareholder, Carl Icahn, supports the change in meeting date. BEA and Mr. Icahn have reached a settlement of the action brought by entities affiliated with Mr. Icahn, pursuant to Section 211 of the Delaware General Corporation Law, to set the date of the annual meeting. The settlement agreement approved by the court confirms that the annual meeting will be held on March 18, 2008.
