Egg Wins 2006 European Business Rules Award with Implementation of Fair Isaac's Blaze Advisor System; United Kingdom's Leading Online Bank Receives ''Best Business Rules Solution'' Award with Credit Management System.

UNITED KINGDOM & MINNEAPOLIS -- Egg, the United Kingdom's leading online bank, and Fair Isaac Corporation (NYSE:FIC), the leading provider of analytics and decision management technology, today announced that Egg's rules-based Credit Management System received the coveted "Best Business Rules Solution" award at this year's 2006 European Business Rules Conference (EBRC).

Recognized against significant competition, Egg demonstrated the versatility, agility and speed of Fair Isaac's Blaze Advisor(TM) business rules management system as an integral part of its Credit Management System. The EBRC award committee selected Egg based on specific factors, including:

--The Credit Management System is owned and driven by Egg's business users.

--Egg developed the rules based system in-house.

--The Credit Management System is a core part of Egg's daily business transactions.

--The adoption and deployment of its Credit Management System had a wide-ranging impact on Egg's business.

--The system supports multiple representations of business rules.

As a recipient of the EBRC 2006 Award, Egg spokesperson Marcus Cripps designated the charitable donation of a EUR 500 award to The Friends of Portway Infants, a charity for advancing the education of young children.

"Egg is proud to have been recognized by this year's 2006 European Business Rules Conference committee," stated Pete Marsden, CIO at Egg. "Competing via the Web, it is critical to provide our banking clients fast, precise decisions and offers for the services they require. The adoption of Fair Isaac's Blaze Advisor system for our Credit Management System allows us to execute transactions quickly with the agility to deliver new offerings created directly by our business analysts making valuable business decisions."

Egg's objective in building the Credit Management System (CMS) included coordinating credit risk decisions (across the bank and across the customer), reducing the amount of manual interventions and linking disparate IT systems. By making more precise and consistent decisions, Egg sought to lower its provisioning for bad debt, increase its acceptance rates and set more appropriate credit limits.

"Egg's success is a great example of how more businesses are using Blaze Advisor to help manage highly complex decisioning processes," said Paul Perleberg, general manager of international operations at Fair Isaac. "Blaze not only allows organizations to execute transactions quickly, but also provides the agility and flexibility to adapt decision strategies as business strategies change."

Fair Isaac's Blaze Advisor system enables Egg's business users to easily set up and change business rules so that new strategies can be put into production faster. Egg built a "Blaze Control Centre" that enables business users to build and test the rules on their PCs. The rules are maintained as a distinct body of knowledge within the Blaze Advisor enterprise rules repository.

Egg has a strong, longstanding relationship with Fair Isaac, and currently uses the company's fraud detection technology, credit risk models and TRIAD(TM) adaptive control system.
