FOR IMMEDIATE RELEASE


                 OLSTEN STOCKHOLDERS APPROVE ADECCO PURCHASE OF
              STAFFING SERVICES AND IT BUSINESSES AND SPLIT OFF OF
                             GENTIVA HEALTH SERVICES


Melville, NY, March 13, 2000 -- Olsten Corporation (NYSE: OLS) announced that at
a special meeting of its stockholders today, owners of a majority of the
outstanding Olsten common stock formally approved the sale of the company's
staffing and information technology services businesses to Adecco SA (NASDAQ:
ADECY; SWX: ADEN 700'939; BOURSE DE PARIS: RM 12819). An integral part of the
sale is the split off of Olsten's health services business, now operating as
Gentiva Health Services.

         The transaction is expected to close on March 15, at which time Olsten
will cease trading on the New York Stock Exchange. On March 16, Adecco will
delist from NASDAQ and begin trading on the NYSE using the symbol ADO. Also on
March 16, Gentiva common stock is expected to be quoted on the NASDAQ National
Market under the symbol GTIV.

         The combination of Adecco and Olsten, which was announced in August
1999, further strengthens Adecco's position as the global leader in staffing
services. The newly merged company will have more than 25,000 full-time
employees serving approximately 250,000 clients worldwide. Pro forma combined
sales for 1999 were in excess of US $15 billion.

         Gentiva Health Services is North America's largest provider of home
health care and related services. A leader in specialty pharmaceutical services
and nursing services solutions, the company has more than 400 locations in North
America. Gentiva also provides marketing and distribution solutions for
pharmaceutical, biotechnology and medical device firms as well as home infusion
therapies, health care network management services, skilled nursing services and
medical staffing solutions. In 1999, Gentiva Health Services had $1.5 billion in
revenue and employed approximately 70,000 associates and caregivers.
