STATE STREET AND DST SYSTEMS MARK 30TH ANNIVERSARY OF BOSTON FINANCIAL DATA SERVICES JOINT VENTURE

BOSTON, Mass.
Oct. 30, 2003

State Street Corporation (NYSE: STT), the world's leading specialist in meeting the needs of institutional investors, and DST Systems, a developer of proprietary software systems for shareholder accounting and recordkeeping services, today mark the 30 year anniversary of the formation of Boston Financial Data Services (BFDS).

Co-founded in 1973, BFDS is a leading provider of automated shareholder recordkeeping for mutual fund management companies. Over the past 30 years, BFDS has built its position as the largest mutual fund transfer agent in the United States, and today employs nearly 2,600 individuals and serves a client base of over 21 million shareholder accounts.

"State Street applauds BFDS' 30 years of growth, expansion and recognition as an established leader in the financial services marketplace," said Jay Hooley, executive vice president of State Street Corporation. "With the demand for quality shareholder services becoming more and more critical as investment products become increasingly complex, our clients value the unique relationship we have developed with BFDS. We are proud to partner with the best in the industry."

"The combination of State Street's investment services expertise coupled with DST's technology capabilities helped build the foundation for our tremendous growth," said Steve Towle, president of BFDS. "We look forward to many more years of providing high quality service to our clients."

In response to growing need for quality shareholder services outside of the United States, State Street and DST introduced International Financial Data Services (IFDS) in 1995. Since its inception, IFDS has also experienced impressive growth and today has expanded to over 1, 700 employees in three locations across the world, supporting over 70 fund companies and managing over 13 million accounts in ten countries. Recent mandates announced by IFDS include Aviva Fund Services and Schroders.

"DST is proud of BFDS' accomplishments over the last 30 years and our partnership with State Street. We look forward to the continuing success at BFDS and the growth of IFDS," said Tom McCullough chief operating officer of DST Systems and chairman of BFDS.

State Street Corporation is the world's leading specialist in providing sophisticated global investors with investment servicing, investment management, research and analytics and trading services. With $8.8 trillion in assets under custody and $965 billion in assets under management, State Street operates in 23 countries and over 100 markets worldwide.
