Advent Receives Deficiency Letter from Nasdaq Stock Market

Advent Receives Deficiency Letter from Nasdaq Stock Market Pending Filing of Form 10-K and Compliance with Nasdaq Requirements

San Francisco, CA, Thursday, April 7, 2005 - Advent Software, Inc. (NASDAQ: ADVS) announced today that the NASDAQ Listing Qualifications Department (the "Nasdaq Staff") has notified the Company that it is not in compliance with the requirements of Nasdaq Marketplace Rule 4310(c)(14) because it has not yet filed its Annual Report on Form 10-K for the period ended December 31, 2004 (the “2004 10-K”) with the Securities and Exchange Commission. Consequently, Advent common stock is subject to delisting from the Nasdaq Stock Market. The Company's delay in filing its 2004 10-K is the only listing deficiency cited by the Nasdaq Staff.

Advent intends to request an appeal hearing before a Nasdaq Listing Qualifications Panel (the "Panel") to review the delisting determination. Under the Nasdaq Marketplace Rules, the delisting of Advent's common stock will be stayed pending the Panel's review and determination. Until the Panel's ultimate determination, the date of which is not yet known, Advent common shares will continue to be traded on the Nasdaq Stock Market, but its trading symbol as of Thursday, April 7, 2005, will be amended from "ADVS" to "ADVSE", to reflect the Company's filing delinquency. Advent disclosed in a Form 8-K filed on March 31, 2005 that the Company’s management was still in the process of completing its assessment of the Company’s internal control over financial reporting, although because of the material weaknesses identified to date, management will conclude that the Company did not maintain effective internal control over financial reporting as of December 31, 2004. The Company intends to file its 2004 10-K on or before Wednesday, April 13, 2005.
