BECTON DICKINSON AND CAREFUSION ANNOUNCE EXPIRATION OF

HSR ACT WAITING PERIOD IN PROPOSED TRANSACTION

Franklin Lakes, NJ and San Diego, CA (November 20, 2014) – Becton, Dickinson and Company (NYSE: BDX) (“BD”) and CareFusion Corporation (NYSE: CFN) (“CareFusion”) today announced that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), in connection with BD’s proposed acquisition of CareFusion expired on November 19, 2014.

As previously announced on October 5, 2014, BD and CareFusion entered into a definitive agreement pursuant to which BD would acquire CareFusion in a stock and cash transaction. The expiration of the HSR Act waiting period satisfies a condition to the proposed acquisition. The proposed acquisition remains subject to certain other conditions and approvals, including, among others, the adoption of the merger agreement by the CareFusion stockholders and the approval of the proposed acquisition by the European Commission under the European Union Merger Regulation.
