EAST HANOVER, N.J.--(BUSINESS WIRE)--June 15, 2004

Conversion Services International, Inc. (CSI - The Center For Data Warehousing) (OTCBB: CSII.OB; "CSI") announced today that DeLeeuw Associates, LLC, its wholly owned subsidiary, is sponsoring this year's Successfully Implementing Six Sigma for Financial Services Conference to be held in New York City from June 23-24, 2004. The conference, hosted by Worldwide Conventions and Business Forums (WCBF), brings together Six Sigma deployment experts.

DeLeeuw Associates will also co-sponsor this year's Six Sigma for Financial Services Conference. The conference, hosted by the International Quality & Productivity Center (IQPC) from July 27-28 2004 in New York City, will focus on using Six Sigma techniques to manage operational risk.

Additionally, Bryan Carey, Executive Vice President and Lean Six Sigma Practice Leader for DeLeeuw Associates, and Joseph T. Walsh, Executive Vice President and Chief Information Officer of DeLeeuw Associates, will lead a panel session at the IQPC conference discussing operational risk on Tuesday, July 27, 2004 at 11:25 a.m. EST. Topics for this panel will cover the role that Lean and Six Sigma can play in meeting many of the issues that financial institutions are facing when dealing with regulatory and compliance issues.

According to Bryan Carey, Executive Vice President and Lean Six Sigma Practice Leader for DeLeeuw Associates, "We are proud to be involved in the WCBF and IQPC conferences. As financial services industry leaders continue to focus on translating customer satisfaction into bottom-line results, Lean and Six Sigma methodologies become increasingly important to enhancing customer experience while improving process performance. These conferences are an opportunity to share best-in-class experiences with professionals who have implemented Six Sigma programs within the financial services industry as it is no longer just a manufacturing methodology."

Mr. Carey continued, "This year's focus of the WCBF conference is on operational risk management, as well as impacting customer experience, which is timely with the Sarbanes Oxley Act deadlines fast approaching. Lean and Six Sigma methodologies, by their very nature, promote a repeatable, sustainable, streamlined approach to 'improving the accuracy and reliability of corporate disclosures made pursuant to the securities laws,' according to the Sarbanes Oxley Act."

"Right now, financial services institutions, along with all companies, are faced with the need to gather the correct data for financial reporting. In addition, financial professionals need to demonstrate an understanding of interrelated processes and infrastructure to ensure that their financial reporting is accurate," said Joseph T. Walsh, Executive Vice President and Chief Information Officer of DeLeeuw Associates. "This is where Six Sigma methodologies and data-driven structure can be leveraged for financial reporting compliance."
