                 McKESSON HBOC, INC. BEGINS OPERATIONS AS THE 
                 WORLD'S LARGEST HEALTHCARE SERVICES COMPANY

SAN FRANCISCO, January 13, 1999 -- McKesson HBOC, Inc. (McKessonHBOC)
(NYSE:MCK), the world's largest healthcare services company, began operations
today. McKessonHBOC provides pharmaceutical supply management and information
technologies across the entire continuum of healthcare, including market-
leading businesses in pharmaceutical and medical-surgical distribution,
information technology for healthcare providers, services for payors and
outsourcing.
        McKessonHBOC serves approximately 5,000 hospitals, 25,000 retail 
pharmacies, 200,000 physicians, 10,000 long-term care sites, 750 home care 
agencies, 600 healthcare payors, 450 pharmaceutical manufactures and 2,000 
medical-surgical manufacturers. While more than 95 percent of the company's 
revenues come from the U.S. healthcare market, McKessonHBOC also has customers 
in 10 other countries.
        "McKessonHBOC has a proven track record for providing information-based 
solutions that reduce costs and improve quality for our customers across the 
full continuum of healthcare," said Mark A. Pulido, president and chief 
executive officer. "We are dedicated to improving healthcare performance by 
delivering the right products and information to the right place at the right 
time to advance the success of our customers as they restructure healthcare 
delivery."
        "McKesson HBOC, Inc. is the leader in fast-growing healthcare segments, 
with favorable dynamics driving growth in each of our markets. McKessonHBOC 
pharmaceutical sales are growing in excess of 15 percent per year and healthcare
information technology revenues are increasing at a rate of more than 25 percent
per year."

        "By coordinating our product and service offerings, we can reduce steps
in the healthcare delivery process," Pulido continued. "As a result, we
anticipate acceleration of our historically strong growth to create further
value for our shareholders. And, we will continue an aggressive acquisition
program to capitalize on supply management and healthcare technology
opportunities."
        Four HBOC executives have joined McKesson's existing corporate officers 
on the new McKessonHBOC Executive Operating Committee:
        -- Charles W. McCall, chairman of the McKessonHBOC Board of Directors, 
formerly HBO & Company (HBOC) chairman and chief executive officer.
        -- Albert J. Bergonzi, group president, Healthcare Information 
Technology, reporting to Pulido. Bergonzi was formerly HBOC president and chief 
operating officer.
        -- David A. Schenk, in the new position of senior vice president, 
Affiliation Team, reporting to Pulido. Schenk will lead a dedicated team 
selected from McKessonHBOC operating and functional units to identify and fully 
capitalize on opportunities to accelerate revenue growth through cross-selling, 
leveraging customer relationships, enhancing existing products and creating new 
products. Schenk, who joined HBOC in 1982, had been senior vice president, 
Enterprise Services, with responsibility for HBOC's Enterprise Services as well
as the services functions of the Charlotte Product Group and CyCare Business
Group. He also led all enterprise project management efforts.
        -- E. Christine Rumsey, senior vice president, Human Resources and 
Administration, also reporting to Pulido. Rumsey, who had been senior vice 
president for Human Resources for HBOC, replaces William A. Armstrong, who is 
retiring after 26 years with McKesson. She joined HBOC in 1981.
        "The newly formed McKessonHBOC Affiliation Team has a goal to identify 
two to three major projects that will deliver significant incremental pre-tax 
income each year," concluded Pulido. "They have a target of pre-tax synergies in
excess of $75 million in fiscal year 2000 from a combination of cost savings and
cross-selling initiatives, and a target of $125 million in the following fiscal 
year."
