PARIS, March 7, 2007 -- ILOG (R) (Nasdaq: ILOG; Euronext: ILO, ISIN: FR0004042364) today announced that SFR, France's second-leading mobile phone operator, has selected ILOG JRules(R), a key offering in ILOG's business rule management system (BRMS) product line, to enhance its customer loyalty program, Garantie Carre Rouge (GCR). As a key component of SFR's Points Engine, the application that supports the GCR program, ILOG JRules enables more comprehensive management of the subscriber base and enhances customer service.

Unlike the previous system which managed the subscriber base at a high level, the new ILOG JRules-powered Points Engine enables individualized management of customer accounts, including policies governing point acquisition and redemption. This means that subscribers who have accumulated bonus points based on their consumer profile, seniority, or specific bonus programs, can more easily use their points to upgrade their cell phones, order gifts (extra call minutes, free SMS or MMS messages), or make charitable contributions.

This new system interfaces with the customer management, sales, billing and CRM systems and is managed by the Customer Service and Channel Relationship Management departments. Because it is based on ILOG JRules, the new Points Engine allows for greater flexibility and configuration of its loyalty management rules, which can now be quickly and easily modified. It also delivers the power and scalability required to quickly implement new customer loyalty programs for special events such as Christmas or Valentine's Day while handling large volumes of data. At last, it offers more features for managing the loyalty point lifecycle and triggering rewards for new or changed subscriptions, as examples.

ILOG has consistently built on its history of product innovation to make it the industry's leading provider of business rule software. Customers of ILOG's award-winning BRMS products include eBay, Equifax, Grupo Santander, Harrah's Entertainment, Visa, Vodafone, Zurich, and many other leading Global 2000 companies and governments worldwide.
