AMERISOURCEBERGEN DRUG CORPORATION

SUPPLEMENTAL RETIREMENT PLAN

(Amended and Restated November 24, 2008)

AMERISOURCEBERGEN DRUG CORPORATION

SUPPLEMENTAL RETIREMENT PLAN

In recognition of the services provided to AmerisourceBergen Drug Corporation (the “Sponsor”) and its Affiliates by certain management and highly compensated employees, the Sponsor and its Affiliates maintain the AmerisourceBergen Drug Corporation Supplemental Retirement Plan (the “Plan”) to provide such employees with retirement benefits that would otherwise be unavailable by reason of certain restrictive provisions of law applicable to the AmerisourceBergen Drug Corporation Participating Companies Pension Plan.
