ITEM 1.  CHANGE IN CONTROL OF REGISTRANT.

         On June 7, 1999, Spring Acquisition Corp. (the "Purchaser"), a Florida
corporation and a wholly owned subsidiary of Ceridian Corporation ("Parent"), a
Delaware corporation, completed its tender offer (the "Offer") for all of the
outstanding shares of voting common stock, par value $.01 per share ("Common
Stock"), of ABR Information Services., Inc., a Florida corporation (the
"Company"), by accepting for payment all of the approximately 28,271,055 shares
(the "Shares") of Common Stock which were validly tendered and not withdrawn.
Upon completion of the Offer, which was made pursuant to the Agreement and Plan
of Merger, dated as of April 30, 1999 and as amended on June 2, 1999, among the
Company, Parent and the Purchaser (as so amended, the "Merger Agreement"),
Parent acquired beneficial ownership of the Shares which represent approximately
98.3% of the outstanding Common Stock. The Merger Agreement provides that after
the purchase of the Shares pursuant to the Offer, the Purchaser will be merged
with and into the Company (the "Merger") on the business day on which certain
conditions in the Merger Agreement are satisfied or waived. Parent's press
release of June 7, 1999 announcing the completion of the Offer is filed as an
exhibit hereto and is incorporated herein by this reference.

         Based on the number of shares validly tendered and not withdrawn
pursuant to the Offer as set forth in the Parent press release of June 7, 1999
and a price per share of Common Stock of $25.50, the Purchaser has paid
approximately $721 million, in cash, for the Shares accepted pursuant to the
Offer. The Purchaser obtained these funds from Parent. Parent obtained $450
million of these funds from a short term loan from Bank of America National
Trust and Savings Association ("Bank of America") pursuant to a Credit Agreement
between Bank of America and Parent dated June 7, 1999. Parent obtained the
remainder of these funds from a $250 million line of credit, from which $210
million has been drawn down and existing cash balances. The $450 million short
term loan was repaid in full by Parent on June 10, 1999 using a combination of
(a) the net proceeds from the sale by Parent of $450 million in senior notes to
a group of institutional investors and (b) existing cash balances.

         The Merger Agreement provides that, if requested by Parent, the Company
will, to the extent permissible, promptly following the purchase by Purchaser of
Shares pursuant to the Offer in accordance with the terms of the Merger
Agreement, take all actions necessary (including calling a special meeting of
the Company's Board of Directors (the "Company Board") or the stockholders of
the Company for this purpose) to cause natural persons designated by Parent to
become directors of the Company (including mailing to the Company's stockholders
the information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder) so that the total number of such persons equals that
number of directors, rounded up to the next whole number, which represents the
product of the total number of directors on the Company Board multiplied by the
percentage that such number of Shares so accepted for payment plus any Shares
beneficially owned by Parent or Purchaser bears to the total number of



                                        2

   3

Shares outstanding at the time of such acceptance for payment. At such time, the
Company shall also cause persons designated by Parent to constitute the same
percentage (rounded up to the next whole number) as is on the Company Board of
(i) each committee of the Company Board; (ii) each board of directors (or
similar body) of each subsidiary of the Company; and (iii) each committee (or
similar body) of each such board. To implement the foregoing, the Company has
agreed to increase the size of the Company Board or use its reasonable efforts
to secure the resignation of directors, or both, as is necessary to permit
Parent's designees to be elected to the Company Board; provided, however, that
at all times prior to the Effective Time there shall be at least three members
of the Company Board who are neither officers of Parent nor designees,
stockholders or affiliates of Parent ("Parent Insiders"). In the event that
Parent's designees are elected to the Company Board after the acceptance for
payment of Shares pursuant to the Offer and prior to the Effective Time (as
defined in the Merger Agreement), the affirmative vote of at least a majority of
the directors of the Company who are not Parent Insiders will be required to (a)
amend or terminate the Merger Agreement by the Company, (b) exercise or waive
any of the Company's rights, benefits or remedies under the Merger Agreement,
(c) extend the time for performance of Parent's and Purchaser's respective
obligations under the Merger Agreement, or (d) take any other action by the
Company Board under or in connection with the Merger Agreement which would
adversely affect the ability of the Company's stockholders to receive the Merger
Consideration.

         Pursuant to Parent's request and as provided in the Merger Agreement,
on June 14, 1999, (i) James E. MacDougald and Suzanne MacDougald resigned as
directors of the Company, and (ii) the three continuing directors elected the
following Parent designees as directors of the Company: Lawrence Perlman
(Chairman and Chief Executive Officer of Parent), Ronald L. Turner (President
and Chief Operating Officer of Parent), John R. Eickhoff (Executive Vice
President and Chief Financial Officer of Parent), and Gary M. Nelson (Vice
President, General Counsel and Secretary of Parent).
