CONCORD, Mass. Feb. 24, 2003-- OneSource Information Services, Inc. (Nasdaq: ONES), a leading provider of business information solutions, today announced a major enhancement to the OneSource® Business Browser(SM) product line, bolstering the company''s overall strategy of helping Global 5000 companies spend less time looking for information and more time building customer relationships. The new Find Executives module allows OneSource subscribers to locate and research top prospects, previous champions, past colleagues, or board of director members by searching over 6 million executive names and 250,000 biographies at more than 1.7 million companies. OneSource has also added 50,000 new companies and 90,000 branch and subsidiary executives from the Directory of Corporate Affiliations. Both enhancements are available immediately to OneSource subscribers.

"Uncovering information on individuals is the hardest research we do, but it is crucial to building a better relationship with the client," said Linda O''Connell, marketing director at Robinson & Cole LLP, a national law firm and OneSource subscriber. "Prior to using the Business Browser product, researching individuals at prospective clients was time consuming and frequently impossible. The only option was to hire an investigative service, which law firms aren''t inclined to do. With the new Executives functionality, the Business Browser product now offers us fast access to background information, resulting in stronger relationships with executives and a better understanding of their business experience."

"The typical sales cycle has become very complex, with multiple decision-makers influencing purchase decisions," said Mary McCabe, general manager, Products and Solutions at OneSource. "OneSource''s latest Business Browser product enhancements make it easier to search a wide range of information sources, locate prospects by name, review background and contextual information, and gain a quicker understanding of an executive''s priorities. By providing faster access to better information, OneSource is helping to shorten the sales cycle and increase productivity and revenue."
