------------------------------------------------------------------------------

         ROSELAND,  NJ, March 7, 2006 - Automatic  Data  Processing Inc (NYSE:
ADP) announced today that Karen E. Dykstra, ADP's chief financial officer, has
resigned  effective May 1, 2006. "After her effective  resignation date, Karen
will provide  transitional  consulting services to the company through the end
of the fiscal year, June 30, 2006," Arthur F. Weinbach,  ADP's chief executive
officer, said.

         Ms. Dykstra will join Plainfield  Asset  Management LLC, a registered
investment  advisor  based  in  Greenwich,  Connecticut,  as  both  the  chief
operating  officer and chief  financial  officer of its new direct lending and
investment business.

         Until a successor is named,  Ms. Dykstra's  current  responsibilities
will be divided between Dan Sheldon,  ADP's corporate  controller,  who joined
ADP in 1984, and Raymond L. Colotti,  ADP's  treasurer,  who has been with the
company  since 1995.  Both Messrs.  Sheldon and Colotti will report to Gary C.
Butler, ADP's president and chief operating officer. Mr. Butler, as previously
announced,  will assume the chief executive  officer role upon Mr.  Weinbach's
retirement on August 31, 2006.

         "Karen has had a terrific  25-year career at ADP and has been a great
asset to our  management  team.  For me  personally,  she has  evolved  into a
trusted advisor as well as a knowledgeable and insightful executive. So I join
our entire  management team in saying we will miss her and we wish her success
in her new career.

         "We will  commence a  successor  process to fill the chief  financial
officer position. In the interim, we are extremely fortunate to have the depth
of  management  and the  talents  of  executives  like Dan and Ray to ensure a
smooth transition," Mr. Weinbach concluded.

         ADP, with $8.5 billion in revenues and approximately  590,000 clients
worldwide,  is one of the  largest  providers  of a broad  range  of  premier,
mission-critical,  cost-effective transaction processing and information-based
business solutions.
