                  HOWEVER, that the event described in this paragraph (ii) which
                  occurs by virtue of any of the following acquisitions shall be
                  deemed not to be a Change in Control of the Company: (A) by
                  the Company or any Subsidiary, (B) by any employee benefit
                  plan (or related trust) sponsored or maintained by the Company

                  controlled by an Acquiring Participant or any group of persons
                  including an Acquiring Participant), provided, that an event
                  that is deemed not to be a Change in Control under this clause
                  (E) shall nevertheless be a Change in Control for all
                  Participants other than any Acquiring Participant; or (F) a
                  transaction (other than one described in paragraph (iii)

                  the Company, if a majority of the Incumbent Directors approve
                  a resolution providing expressly that the acquisition pursuant
                  to this clause (F) does not constitute a Change in Control of
                  the Company under this paragraph (ii);

                           (iii) the consummation of a merger, consolidation,
                  statutory share exchange or similar form of corporate
                  transaction involving the Company or any of its subsidiaries
                  that requires the approval of the Company's stockholders,
                  whether for such transaction or the issuance of securities in
                  the transaction (a "Reorganization"), or sale or other
                  disposition of all or substantially all of the Company's
                  assets to an entity that is not an affiliate of the Company (a
                  "Sale"), unless immediately following such Reorganization or
                  Sale: (A) more than 50% of the total voting power of (x) the
                  corporation resulting from such Reorganization or the
                  corporation which has acquired all or substantially all of the
                  assets of the Company (in either case, the "Surviving
                  Corporation"), or (y) if applicable, the ultimate parent
                  corporation that directly or indirectly has beneficial
                  ownership of 100% of the voting securities eligible to elect
                  directors of the Surviving Corporation (the "Parent
                  Corporation"), is represented by Company Voting Securities
                  that were outstanding immediately prior to such Reorganization
                  or Sale (or, if applicable, is represented by shares into
                  which such Company Voting Securities were converted pursuant
                  to such Reorganization or Sale), and such voting power among
                  the holders thereof is in substantially the same proportion as
                  the voting power of such Company Voting Securities among the
                  holders thereof immediately prior to the Reorganization or
                  Sale, (B) no person (other than any employee benefit plan (or

                  Parent Corporation), is or becomes the beneficial owner,
                  directly or indirectly, of 25% or more of the total voting
                  power of the outstanding voting securities eligible to elect
                  directors of the Parent Corporation (or, if there is no Parent
                  Corporation, the Surviving Corporation) and (C) at least a
                  majority of the members of the board of directors of the
                  Parent Corporation (or, if there is no Parent Corporation, the
                  Surviving Corporation) following the consummation of the
                  Reorganization or Sale were Incumbent Directors at the time of
                  the Board's approval of the execution of the initial agreement
                  providing for such Reorganization or Sale (any Reorganization
                  or Sale which satisfies all of the criteria specified in (A),
                  (B) and (C) above shall be deemed to be a "Non-Qualifying
                  Transaction"); or

                           (iv) the stockholders of the Company approve a plan
                  of complete liquidation or dissolution of the Company.

         Notwithstanding the foregoing, a Change in Control of the Company shall
         not be deemed to occur solely because any person acquires beneficial
         ownership of more than 25% of the Company Voting Securities as a result
         of the acquisition of Company Voting Securities by the Company which
         reduces the number of Company Voting Securities outstanding; PROVIDED,
         THAT if after such acquisition by the Company such person becomes the
         beneficial owner of additional Company Voting Securities that increases
         the percentage of outstanding Company Voting Securities beneficially
         owned by such person, a Change in Control of the Company shall then
         occur.

                  (f) "Company" means ABR Information Services, Inc. and any
         successor thereto.

                  (g) "Date of Termination" means the date on which a

         who is covered by a collective bargaining agreement to which the
         Company or any Subsidiary is a party, who is selected to participate in
         the Plan in accordance with Section 2.

                  (l) "Plan" means this ABR Information Services, Inc. Retention
         Bonus Plan as set forth herein and as amended from time to time.

                  (m) "Retention Benefits" means the benefits payable in
         accordance with Section 3 of this Plan.

                  (n) "Subsidiary" means any entity, whether incorporated or
         unincorporated, of which at least a majority of the securities or
         ownership interests having by their terms ordinary voting power to

         similar functions is directly or indirectly owned or controlled by the
         Company, by one or more of the Company's Subsidiaries or by the Company

initial Participants as of the Effective Date are listed on Schedules A and B.
The Administrator shall have the authority to add additional Participants or
remove Participants from the Plan, and shall inform an individual as soon as
practicable following his or her addition or removal from participation in the
Plan; PROVIDED, that no Participant may be removed from participation in the
Plan following a Change in Control until April 1, 2000. A Participant shall
cease to be a Participant in the Plan when he or she ceases to be an Employee,
unless such Participant is entitled to payment of Retention Benefits as provided
in the Plan. A Participant entitled to payment of Retention Benefits shall
remain a Participant in the Plan until the full amount of the Retention
Benefits, and any other obligation under this Plan, has been paid to such
Participant.


                  3. RETENTION BENEFITS

                  (a) In the event the Company enters into an agreement, the
consummation of the transactions contemplated by which would result in a Change

an Employee during the period ("Tier I Benefit Period") commencing on the
Effective Date and ending on the date set forth on Schedule A shall be entitled
to receive the amount set forth on Schedule A.

                  (b) Notwithstanding anything in this Plan to the contrary, if
a Participant's employment is terminated during the Tier I Benefit Period by an
Employer other than for Cause, such Participant shall be deemed to satisfy the
requirements of, and shall be entitled to receive the amounts that would have
been payable to such Participant under, Section 3(a).

                  (c) Any amounts payable under this Section 3 shall be paid in
a single lump sum cash payment. The amount payable under Section 3(a) shall be
paid no later than 10 days following the expiration of the Tier I Benefit
Period, as the case may be. The amounts payable under Section 3(b) shall be paid
no later than 10 days following a Participant's Date of Termination.

                  (d) The Retention Benefits shall be payable in addition to,
and not in lieu of, all other accrued, vested or deferred compensation, rights,
options or other benefits which may be owed to a Participant following
termination of employment, including but not limited to accrued sick pay,
amounts or benefits payable under any bonus or other compensation plan, stock

any contest or dispute shall arise under this Plan involving termination of a
Participant's employment with an Employer or involving the failure or refusal of
the Company to perform fully in accordance with the terms hereof, the Company
shall reimburse such Participant, on a current basis, for all reasonable legal
fees and expenses, if any, reasonably incurred by such Participant in connection
with such contest or dispute (regardless of the result thereof), provided, that,
if it is determined by a court or by arbitration that such Participant did not
enter into the contest or dispute in good faith, such Participant shall be
obligated to return to the Company such reimbursed fees and expenses. All
disputes hereunder shall be settled exclusively by arbitration in Florida in
accordance with the rules of the American Arbitration Association then in
effect. Judgment may be entered on the arbitration award in any court having
jurisdiction. The Company shall bear all costs and expenses in connection with

                  6. PARTICIPATING EMPLOYERS. Each Subsidiary shall,
automatically and without any action on the part of such Subsidiary, be deemed
an Employer and the provisions of this Plan shall be fully applicable to the

                  (a) Subject to paragraph (b) below, this Plan shall be in
effect as of April 30, 1999, and shall terminate on June 30, 2000, unless
terminated at an earlier date by the Company.

                  (b) The Company shall have the right prior to a Change in
Control, in its sole discretion pursuant to action by the Board, to terminate or
amend the Plan. Notwithstanding anything in paragraph (a) of this Section 7 to
the contrary, in no event shall this Plan be terminated or amended during the
period following a Change in Control and prior to June 30, 2000 in any manner
which would adversely affect the rights or potential rights of Participants
under this Plan with respect to such Change in Control.

                  8. SUCCESSORS.

                  (a) This Plan shall not be terminated by any merger,
consolidation, share exchange or similar event involving the Company whereby the
Company is or is not the surviving or resulting entity. In the event of any
merger, consolidation, share exchange or similar event, the provisions of this
Plan shall be binding upon the surviving or resulting corporation or the person
or entity to which the Company's assets are transferred.

                  (b) Concurrently with any merger, consolidation, share
exchange or sale, lease or transfer of all or substantially all of its assets,
the Company will cause any successor or transferee unconditionally to assume all
of the obligations of the Company and the Employers hereunder.

                  (c) This Plan shall inure to the benefit of and be enforceable
by each Participant's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If a
Participant shall die while any amounts are payable to such Participant
hereunder, all such amounts, unless otherwise provided herein, shall be paid in
accordance with the terms of this Plan to such Participant's surviving spouse
or, if none, to such Participant's estate.

<PAGE>

                  9. NO MITIGATION. The obligation of the Company to provide a
Participant with the benefits specified in Section 3 and otherwise to perform
its obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action which the Company or any
Employer may have against such Participant or others. In no event shall a
Participant be obligated to seek other employment or take other action by way of
mitigation of the amounts payable to such Participant under any of the
provisions of this Plan and such amounts shall not be reduced whether or not
such Participant obtains other employment.

                  10. GOVERNING LAW; VALIDITY. The interpretation, construction
and performance of this Plan shall be governed by and construed and enforced in
accordance with the laws of the State of Florida without regard to the principle
of conflicts of laws. The invalidity or unenforceability of any provision of
this Plan shall not affect the validity or enforceability of any other provision
of this Plan, which other provisions shall remain in full force and effect.

                  11. ADMINISTRATION. The Plan shall be administered by the
Administrator. The Administrator shall provide adequate written notice to any
Participant whose claim for Retention Benefits has been denied, setting forth
specific reasons for such denial, written in a manner calculated to be
understood by such Participant, and affording such Participant a full and fair
review of the decision denying the claim.

                  12. MISCELLANEOUS.

                  (a) Neither the Company nor any Employer shall be required to
fund or otherwise segregate assets to be used for the payment of any benefits
under the Plan. The Company shall make such payments only out of its general
corporate funds, and therefore its obligation to make such payments shall be
subject to any claims of its other creditors having priority as to its assets.

                  (b) This Plan does not constitute a contract of employment or
impose on the Company or a Participant's Employer any obligation to retain such
Participant as an Employee, to change the status of such Participant's
employment, or to change the policies of the Company or its Subsidiaries
regarding termination of employment.

                  (c) No rights of any Participant (or beneficiary) to payments
of any amounts under the Plan shall be sold, exchanged, transferred, assigned,
pledged, hypothecated or otherwise disposed of other than by will or by the laws
of descent and distribution.

                  (d) Unless the Company specifically provides otherwise, any
Retention Benefits payable under this Plan shall not be taken into account for
purposes of determining benefits payable to a Participant under any other
benefit plan or program of an Employer.

                  (e) The Company's obligations hereunder shall be subject to
all applicable laws, and Retention Benefits payable hereunder may be adjusted to
comply with any such laws.
