               Sell Its Water Products Business to Groupe DANONE
                               for $1.1 Billion

     SAN FRANCISCO--(BUSINESS WIRE)--Jan. 11, 2000--McKesson HBOC, Inc.
(NYSE:MCK) (McKessonHBOC) announced today that it has signed a definitive
agreement with the Groupe DANONE (NYSE:DA) whereby DANONE will purchase the
McKesson Water Products Company, a subsidiary of McKessonHBOC, for a total
consideration of $1.1 billion in cash.

     The transaction has been approved by the Boards of Directors of both
companies and is subject to regulatory review and other customary conditions.

marketer and distributor of bottled water in the United States. The company
markets bottled water in 30 states under the Sparkletts(R), Alhambra(R) and
Crystal(TM) brands. McKesson Water Products has expected revenues of more than
$380 million with an EBITDA margin of 22% in its fiscal year ended March 31,
1999.

     "Given our strategic focus on improving healthcare quality and cost through
our market-leading positions in healthcare information technology and supply
management, McKesson Water Products was not a core business," said John H.
Hammergren and David L. Mahoney, McKessonHBOC co-presidents and co-chief
executive officers.

     "We believe that this transaction is in the best interests of both our
shareholders and the Water Products Company employees who have created
significant value in this business. We wish them well as they become a key
element of DANONE's U.S. bottled water business."
