Nasdaq Board of Directors Grants Stay to BEA Systems

SAN JOSE, CA – September 20, 2007 – BEA Systems, Inc., a world leader in enterprise infrastructure software, today announced that on September 14, 2007, it received a letter from the Board of Directors of The NASDAQ Stock Market LLC (the “Nasdaq Board”) informing BEA that the Nasdaq Board had determined to grant BEA until November 14, 2007 to file all delinquent periodic reports necessary for BEA to regain compliance with its Nasdaq filing requirements.

As previously disclosed, in August 2006, the Audit Committee of BEA’s Board of Directors initiated a review of BEA’s historical stock option grants. On December 4, 2006, BEA announced that it expected changes in certain stock option measurement dates to result in material, non-cash compensation expenses, and, therefore, that its previously issued financial statements should no longer be relied upon and that it would restate its financial statements as necessary. On February 14, 2007, BEA announced the principal conclusions of the Audit Committee’s review. BEA is working with its independent auditors, Ernst & Young LLP, to complete its restatement, and thereafter intends to seek comments from the Office of the Chief Accountant (the “OCA”) at the Securities and Exchange Commission. BEA intends to file its delayed quarterly reports on Form 10-Q for the quarters ended July 31, 2006, October 31, 2006, April 30, 2007 and July 31, 2007, and its delayed annual report on Form 10-K for fiscal year ended January 31, 2007, which will incorporate its restated financial statements, as soon as practicable after receiving comments from the OCA. However, there can be no assurance that BEA will complete the preparation and filing of the described periodic reports in time to meet any deadlines imposed by Nasdaq, or that BEA’s common stock will remain listed on The Nasdaq Global Select Market.
