(1) The ratios of earnings to fixed charges for AmerisourceBergen were
calculated using summary unaudited pro forma consolidated statement of
operations data for the year ended September 30, 2000, and nine months ended
June 30, 2001. The summary unaudited pro forma consolidated statement of
operations data used in the calculations were prepared under the purchase method
of accounting as if the merger between AmeriSource and Bergen and the related
financing transactions had been completed on October 1, 1999. We have included
this information only for purposes of illustration, and it does not necessarily
indicate what the ratios of earnings to fixed charges would have been if the
merger and the related financing transactions had been completed on October 1,
1999. Moreover, this information does not necessarily indicate what the future
ratios of earnings to fixed charges will be. You should read this exhibit in
conjuction with the "AmerisourceBergen Corporation Unaudited Pro Forma
Consolidated Condensed Financial Information" included herein.

(2) For financial statement purposes, interest expense includes income earned on
temporary investment of excess funds and amortization of deferred financing
fees.
