MOUNTAIN VIEW, Calif., Oct. 31, 2006 -- ILOG(R) (Nasdaq: ILOG; Euronext: ILO, ISIN: FR0004042364) and Tavant Technologies today announced an agreement to partner on mortgage lending solutions. Tavant will leverage ILOG JRules(TM), a key offering in ILOG's business rule management system (BRMS) product line -- which is already used widely in the mortgage lending space -- as a key component of Tavant Mortgage Solutions, a service that combines deep mortgage domain expertise, pre-built functionality components and global delivery to help lenders rapidly build and enhance existing origination, servicing and capital market systems. The two companies also announced the successful deployment of a sales automation solution at Ameriquest Mortgage Company.

Tavant has deep expertise in working with mortgage lenders to develop solutions for achieving higher lead conversion rates, lowering processing costs per loan, optimizing key servicing indicators such as default rates and minimizing the cost of securitization. The company has accumulated more than 2500 person-years of application development experience across the entire mortgage lifecycle. For the Ameriquest deployment, Tavant used ILOG JRules as a key component in the development of a scalable and extensible SOA-based solution for automating and integrating the end-to-end sales process, including lead management, credit review, loan proposal generation and receipt of borrower commitment.

"The solution developed by Tavant and ILOG has helped us operate our business more efficiently, making faster and more consistent business decisions, responding more quickly to customers, and adapting more effectively to changing business conditions," said Mark Sarago, CIO at Ameriquest Mortgage Company. "With Tavant's services and software solutions from ILOG, we were able to take a more holistic, cost-effective approach to our infrastructure and implement a service-oriented architecture that has increased our agility, ensured long-term value and lowered the total cost of ownership."

According to TowerGroup, BRMS is a key infrastructure component for supporting lending operations, including loan origination, loan underwriting, funding and closing, servicing, and portfolio management.

As part of Tavant's mortgage industry solutions, ILOG's BRMS family of products offer companies increased competitiveness by helping them capture market opportunities more efficiently, shorten the time it takes to roll out new products, match mortgage products to customers based on a full customer profile automatically and in real-time, and automate identification of cross-sell and up-sell opportunities. The solutions improve operational efficiency by automating routine tasks, freeing up time for users such as the underwriters to focus on more complex situations and exceptions. By enabling business users to manage loan and credit rules themselves, the IT organization is also relieved of day-to-day tasks. The solutions also help companies comply with mounting government regulations by ensuring consistency, auditability and by providing visibility into the decisioning process.

"Our mortgage industry customers must effectively automate their business rules in order to achieve the full benefits of business process improvements," said Sarvesh Mahesh, CEO of Tavant Technologies. "By integrating ILOG's BRMS software into our business process solutions, we can provide our customers with more comprehensive functionality using proven technology that can deliver huge gains in operational efficiency, agility, and cost control."

ILOG has consistently built on its history of product innovation to make it the industry's leading provider of business rule management system software. Gartner positioned ILOG in the leader's quadrant of Gartner's 2005 Magic Quadrant for Business Rule Engines, and Forrester Research recognized ILOG as a rules platform market leader, including the leader in rules platforms for Java. 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.
