                   ADP REPORTS SECOND FISCAL QUARTER RESULTS;
                     REVENUES INCREASE 9%, EPS DECLINES 12%;
               FISCAL 2004 EPS GUIDANCE NARROWED TO $1.53 - $1.58


      ROSELAND, NJ, January 22, 2004 - Automatic Data Processing, Inc.
(NYSE:ADP) reported 9% revenue growth, with revenues of $1.8 billion and $.38
earnings per share for the second fiscal quarter ended December 31, 2003, Arthur
F. Weinbach, chairman and chief executive officer, announced today. Pretax and
net earnings declined 14% and 13%, respectively. Diluted earnings per share, on
fewer shares outstanding, declined 12% from $.43 per share last year.

      Commenting on the quarter, Mr. Weinbach said, "Revenue growth was ahead of
our plan for the quarter primarily in Brokerage Services. Revenues in Employer
Services, Brokerage Services and Dealer Services grew 9%, 7% and 8%,
respectively. Claims Services revenues declined 5% primarily due to the
previously announced exiting of our Medical Claims Business. As anticipated,
earnings continue to be impacted by lower interest rates, our incremental
investment activity which will continue to increase over the fiscal year, and by
dilution from last year's acquisitions.

      "Employer Services' sales growth was 2% in the second quarter compared
with last year. This result is close to our plan and an improvement over the
prior four quarters' sales results. We have seen increased interest in
comprehensive outsourcing arrangements with large employers that include Managed
Payroll, Human Resources and Benefits Administration, and have created a
dedicated organization within our National Accounts segment to support the
growth in demand for these services.

      "Employer Services' client retention continued to be strong, improving
slightly over last year's record retention levels. The critical year-end
retention period is still ahead of us, but we are pleased with our results so
far. The number of employees on our clients' payrolls, or "pays per control",
was relatively flat in North America. However, pays per control in our European
businesses is still declining, with individual country results ranging from flat
to down 3% compared to last year. Employer Services' margin declined due to the
increased investment spending as well as the continued integration of last
June's ProBusiness Services and other acquisitions. Brokerage Services' revenue
growth was primarily driven by an increase in investor communications activity.
Non-proxy mutual fund mailings were especially strong compared with last year
based on increased communications related to regulatory oversight.

      "We are slightly ahead of our plans as we move into the second half of the
fiscal year and the overall outlook for ADP has turned more positive based on
better momentum in the brokerage markets, improving economic conditions and
increasing confidence that there will be no further interest rate declines. As
we are halfway through our fiscal year and have increased visibility on our key
metrics, we are narrowing the range of our fiscal 2004 earnings per share
guidance to $1.53 - $1.58 from previous guidance of $1.50 - $1.60. We continue
to forecast mid-single digit revenue growth. We anticipate stronger sales growth
in Employer Services during the second half of the year, due in part to easier
comparisons and also due to our investments in products and a larger U.S. sales
force. Our investment spending increased to about $30 million in the quarter,
about $50 million year-to-date, and we are on track to spend approximately $130
- $145 million for the fiscal year.

      "We have continued to acquire ADP shares for treasury. During the first
half of fiscal 2004, we acquired over 7 million shares for approximately $270
million," Mr. Weinbach concluded.

      An analyst conference call to review the second quarter results will be
held today, Thursday, January 22 at 1:30 p.m. EST. A live audio webcast of the
call will be available to the public on a listen-only basis. To listen to the
webcast go to www.adp.com and click on the webcast icon. ADP's news releases,

      ADP, with over $7 billion in revenues and approximately 500,000 clients,
is one of the largest independent computing services firms in the world.

(B)   Prior year's segment  results were adjusted to reflect fiscal
      year 2004  budgeted  foreign  exchange  rates.  In  addition,
      Employer   Services'  prior  year  revenue  was  adjusted  to
      include  interest  earned on client  funds  credited at 4.5%.
      Employer   Services'  revenues  are  credited  with  interest
      earned on client  funds at a  standard  rate to better  judge
      real business growth without the impact of changing  interest
      rates.  Given the sustained  lower interest rates over recent
      years, ADP has changed the standard rate from 6.0% to 4.5%.
