PARIS and MOUNTAIN VIEW, Calif., November 13, 2002 - ILOG� (NASDAQ: ILOG; Euronext SICOVAM: 006673), the leading provider of enterprise-class software components, today announced that Financial Engines�, Inc., a leading provider of advice technology and services, has selected ILOG CPLEX� for its industry-leading advice technology platform. Financial Engines has alliance relationships with more than 15 financial institutions, including J.P. Morgan/American Century Retirement Plan Services and Northern Trust Retirement Consulting. In addition, over 800 employers, including 3Com Corporation, Dow Corning and The Goodyear Tire & Rubber Company*, use Financial Engines' advice technology and services to provide investment forecasting and advice to more than three million individuals.

Millions of Americans have retirement plans, usually through their employers. However, most plan participants either lack the time or experience to manage a diversified portfolio. Financial Engines enables financial institutions and employers to offer fully integrated, consistent and cost-effective investment advice to their clients and employees through the Web, phone or face-to-face.

In its continued pursuit to develop unparalleled advice technology, Financial Engines has adopted ILOG CPLEX to create a more advanced optimization framework that enhances Financial Engines' ability to create intuitive and actionable investment advice by taking into account the myriad of complexities encountered in real-world portfolio optimization. The enhanced optimization capabilities ensure that the advice given customers reduces portfolio turnover, minimizes taxes, incorporates transaction costs, avoids trace allocations, and handles minimum investment constraints.

For example, the system will suggest customers remain with current portfolio positions if the anticipated gains aren't significant enough to justify the transaction costs. These enhancements also ensure that the client or advisor can easily implement the advice.

"We're committed to providing financial institutions and employers with the advanced technology they need to deliver advisory services to their clients and employees," said Garry Hallee, executive vice president, Financial Engines. "As demand for our platform increases, along with the requirements for functionality and performance, best of breed technology that can handle this growth has become crucial to us for maintaining our competitive edge. ILOG CPLEX can help us meet these objectives."

"Financial Engines has taken the relationship mainstream investors have with their retirement portfolios to the next level," said ILOG's vice-president for Strategic Business Development, Eric Brisson. "Clearly, we're pleased at the success of Financial Engines' advice technology platform, since it underscores the power of ILOG optimization to support intelligent, real-time advice over the Web."
