Advent Software Board Authorizes Stock Buy-Back Plan

San Francisco, March 5, 2001 - Advent Software, Inc. (Nasdaq: ADVS) announced that its Board of Directors authorized a stock buy-back plan. The authorization is for the repurchase of up to one million shares of outstanding common stock. As of December 31, 2000, Advent had approximately 30.5 million common shares outstanding.

"Each and every Advent employee has an opportunity to become a part owner of our dynamic organization through the granting of stock options," stated Irv Lichtenwald, Chief Financial Officer of Advent Software. "Although this can be a great motivator of morale and improved productivity which benefits shareholders, it increases the number of Advent common shares outstanding. This stock buy-back program will allow us to help manage the dilution of our shares as our company grows and expands."

The purchases may be made, from time to time, on the open market or in privately negotiated transactions and will be funded from available working capital. The number of shares to be purchased and the timing of the purchases will be based on the level of cash balances, general business conditions and other factors, including alternative investment opportunities.
