BillMatrix Unit of Fiserv Repeats Strong Role at NACHA’s Annual Event
Major Insurance Company Presenting Receivables Integration Case Study

DALLAS, Texas – May 4, 2006 – BillMatrix Corporation, a provider of outsourced telephone- and Internet-based payment services and a business unit of Fiserv, Inc. (Nasdaq: FISV), announced today a full slate of activities at PAYMENTS 2006, NACHA's annual conference on electronic payments and e-business. This year the premier payments industry conference is being held in San Diego, Calif. from May 7-10 at the San Diego Convention Center.

Jerry Portocalis, BillMatrix’ executive vice president of sales and marketing, will be jointly presenting a national insurance client’s successful experience with electronic payments on Tuesday, May 9 at 11:15 AM. This top-50 insurance company is focused on delivering world-class performance to their customers in the property and casualty arena and committed to meet the needs of their independent agents. Their insureds and agents saw the benefit of electronic options in other industries and needed that same convenience and control for insurance premium payments. The session will describe how existing technology to support bill printing and delivery was leveraged to simplify the integration of electronic payments for both constituencies.

Portocalis has taken a very active role with NACHA and its sister organizations over a number of years. He is currently in his second term as Marketing/Public Relations chair on the steering committee for NACHA’s Council for Electronic Billing and Payments and was a featured speaker on PIN-less debit at NACHA’s e-Check Conference in 2005.

Portocalis and other BillMatrix executives are participating in other presentations at the event, moderating several sessions on a wide range of subjects related to billing and bill payment. BillMatrix will showcase their comprehensive electronic payment services at the NACHA Payments Conference booth #420, demonstrating the ease of making a payment for the customers of utility, insurance, telecommunications, mortgage and other financial services companies.
