AmerisourceBergen Names Michael D. DiCandilo Senior Vice President and Chief Financial Officer

March 4, 2002

DiCandilo succeeds Neil F. Dimick, who, as previously announced, is leaving AmerisourceBergen for personal reasons. Dimick will remain with the Company through April to ensure a smooth transition.

"It is a great pleasure to appoint Mike to this new role. He brings to the job the demonstrated financial discipline needed to continue to drive AmerisourceBergen's performance," said Yost. "He is a strong, hands-on leader, and his unique background in both field and corporate operations has given him a broad, in-depth understanding of the business."

Added Kurt J. Hilzinger, AmerisourceBergen Executive Vice President and Chief Operating Officer, "Mike and I have worked together for over a decade, and he is an extremely capable finance executive who possesses a uniquely strong combination of technical expertise and business acumen. He knows our business as well as anybody in the industry and undoubtedly will continue to be a strong contributor."

"I am excited about taking on this new leadership role and helping to deliver continued value to our shareholders," said DiCandilo. "I am convinced AmerisourceBergen has tremendous potential. We have $150 million in annual cost-saving synergies from the AmeriSource Health Corporation and Bergen Brunswig Corporation merger to capture by the end of fiscal 2004; we are building the most efficient distribution network in the industry; and we are expanding customer services and solutions all along the pharmaceutical supply chain."

DiCandilo was named AmerisourceBergen's Vice President and Corporate Controller in October of last year, shortly after the merger of AmeriSource Health and Bergen Brunswig. He joined the former AmeriSource 12 years ago as Regional Vice President of Finance for the company's northeast region. Five years later, DiCandilo was appointed AmeriSource's Vice President and Controller, where he played a critical role in transforming financial administrative functions from a decentralized to a centralized model. Prior to joining AmeriSource, he served eight years with Ernst & Young in a variety of accounting management positions.

DiCandilo is a Certified Public Accountant and holds a Bachelor of Science degree in accounting from the Wharton School of the University of Pennsylvania, where he graduated summa cum laude.
