SAN FRANCISCO – April 24, 2007 – Advent Software, Inc.

AWM Investment Co., Inc., a $1.3 billion, SEC-registered hedge fund manager, is among the Advent customers that have recently adopted Moxy®.  “With Moxy®, I can enter and track my orders, see what my target is, what my working orders are, what trades I’ve completed, and what broker I am using,” said Tom Fradella, Head Trader at AWM Investment Co.  “Moxy® keeps track of everything.”
 
Moxy® enables fast, precise trade creation and improved order execution.  It streamlines the trade order management process to help traders scale their businesses, handle more accounts with fewer resources and improve connectivity with counterparties.  Moxy® allows Advent customers to execute large block orders easily and quickly without sacrificing efficiency.
 
“Everything is now on my Moxy® platform, and it’s easy for everyone in the firm – portfolio managers, senior partners and others – to sign on to Moxy® and see everything that the desk is involved in,” continued Mr. Fradella.  “Everyone can track where we stand, how many shares are open, what we’re working to – basically, it’s put us all on the same page.”
 
“We’re excited to welcome our newest Moxy® clients and pleased by the strong momentum we’re seeing for our entire suite of solutions,” said Pete Hess, Executive Vice President and General Manager of Advent’s IMG business.  “Advent is delivering on our vision of providing the investment management industry with the most comprehensive suite of mission-critical software and services, which we continually look to enhance.  We are proud to play a role in the success and growth of our more than 750 Moxy® clients, and we look forward to meeting their trading needs now and in the future.”
