Morris and Morris Announces Class Action Against Certain Officers and Directors of McKessonHBOC Alleging Misrepresentations.

NEW YORK--(BUSINESS WIRE)--June 9, 1999--

The following is an announcement issued by Morris and Morris:

A class action lawsuit was filed on June 4, 1999 in the United States District Court for the Northern District of Georgia, Atlanta Division, seeking to pursue remedies under the Securities Exchange Act of 1934, on behalf of all who purchasers of the common stock of McKessonHBOC Corp. or its predecessor McKesson Corp (NYSE:MCK) ("McKesson" or the "Company") between November 27, 1998, and April 28, 1999, inclusive (the "Class Period"), except for persons who received McKesson stock in exchange for shares of HBO & Company ("HBOC") in the Jan. 12, 1999 merger of McKesson and HBOC.

The class action complaint alleges a fraudulent scheme and deceptive course of conduct by certain individuals, officers and/or directors first of HBOC and later of McKesson, who disseminated materially misleading statements during the Class Period. Specifically, these individuals oversaw HBOC operations prior to the merger of McKesson and HBOC, and McKesson's healthcare software business after the merger, and publicly reported supposedly skyrocketing software revenues at HBOC and McKesson. As these individuals knew or recklessly disregarded, however, these revenue figures were artificially inflated through the use of improper accounting techniques including the recording of sales revenue on non-final contingent software sales. These false and misleading revenue figures caused the price of McKesson stock to be artificially inflated throughout the Class Period, injuring purchasers of McKesson stock during the Class Period.

Plaintiff seeks to recover damages on behalf of class members and is represented by, among others, the law firm of Morris and Morris. Morris and Morris is a law firm that concentrates on litigating class actions on behalf of investors and shareholders under the federal securities laws.

If you are a member of the Class described above, you may move the Court to serve as lead plaintiff to the Class within 60 days of June 4, 1999.
