- O2's Transformational 'Vision' Customer Experience Application, Based 
on Chordiant, Captures Best Product Category

Chordiant Software, Inc. (NASDAQ: CHRD), the leading provider of Customer
Experience (Cx(TM)) software and services, today announced that its customer,
O2, one of Britain's leading mobile telecommunications providers, has won
Data Strategy magazine's award for 'Best Applied Data Mining/Modeling
Product.' The competitively judged prize was awarded for the most effective
use of data and modeling to achieve measurable business outcomes. O2 was
given the award by demonstrating actual revenue uplift and improved customer
satisfaction as a result of using Chordiant's decisioning application
throughout its contact centres.

"We are thrilled to be recognized for the all the hard work the team put
in to deliver a system that O2 Advisors use daily and which actually delivers
positive results back to the business. In addition, the O2 and Chordiant
teams have really demonstrated an O2 'can do spirit' by developing
leading-edge work in the industry," said Simmi Bajaj, O2.

O2 recognized it had a need for an application that would improve the
customer experience and drive revenue. It also identified that it could gain
a competitive advantage from such an application. By providing a single
customer view, a more positive agent experience translates into a better call
as agents spend more time having relevant conversations with customers,
rather than searching for information. Using the application, incremental
revenue has been significant.

The O2 Vision application is powered by patented Chordiant Decision
Management (CDM) technology. It enables O2 to tailor their services, response
and offers to individual customer profiles and needs, in real-time. With
Vision, O2 is able to analyse service, revenue and retention issues during
the customer conversation to deliver actionable recommendations that provide
a unique "next best action" for each individual customer. This allows O2 to
be more customer focused, rather than sales focused, during each customer
contact.

"The results obtained by our customer O2 are an excellent example of the
significant benefits true customer-centricity can deliver for global brands,"
said Steven S. Springsteel, chairman, president, and CEO, Chordiant Software.
"Winning this prestigious award is great recognition for the work we're doing
to help businesses change the way they view and treat their customers. Our
market leading customers in telco, healthcare/insurance, and financial
services are discovering that with Chordiant, they can place their customer
at the centre of their business while increasing profitability. Nothing is
better than this."
