Advent’s Moxy® to Provide Scalable, Flexible Trade Order Management Solution to Banks and Trusts

San Francisco, CA, April 12, 2004 - Advent Software, Inc. (NASDAQ: ADVS) announced that it has released a version of its leading Moxy® trade order management application designed to be highly effective for banks and trusts that employ trust accounting systems as their system of record. Previously, Moxy® has been available primarily as an integrated solution with Axys®, Advent’s portfolio management and performance reporting solution. This version, which can work independently of Axys®, integrates with all of the industry’s major trust accounting systems, allowing banks and trusts to benefit from Moxy’s® flexible trade order management capabilities to reduce compliance risk, increase productivity, and automate manual trade entry.

Currently used by more than 650 firms, Moxy® is a robust trade order management system with extensive functionality, including comprehensive equity and fixed income instrument coverage, integration to third-party back office trust accounting systems, enhanced internal security “checks and balance” functionality, and flexible, certified FIX connectivity to trade counterparties, including brokers and alternative trading platforms.

SEI INVESTMENTS TO OFFER MOXY® AS HOSTED SOLUTION
This release of Moxy® includes real-time integration with SEI Investments’ portfolio processing and accounting system. SEI is a leading global provider of asset management and investment technology solutions, and an Advent integration partner. SEI will make the solution available to banks and trusts in a hosted environment.
"We at SEI are gratified to have participated in the development of this new version of Moxy® and are pleased that our client partners will benefit from our work with Advent," said Kevin Barr, head of brokerage and electronic trading services at SEI Investments. "We believe that Moxy’s® increased integration with SEI’s portfolio processing and accounting system will assist us in providing our clients with a more comprehensive investment management solution - reducing risk and cost, increasing efficiency, and enhancing the overall end client experience."

With this version we’re featuring extensive integration to trust accounting systems specifically geared to the way banks and trusts operate, and we feel confident that these firms will benefit greatly from Moxy’s® functionality," said Dan Nye, executive vice president of Advent.
