                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 April 30, 1998


      On April 30, 1998, ABR Information Services, Inc., (collectively with its
subsidiaries, the "Company"), acquired (the "Acquisition") all of the issued and
outstanding capital stock of Business Computer Services, Inc. (d.b.a.
PayAmerica(R)), a Virginia corporation ("BCSI"), in exchange for 1,198,008
shares of the Company's voting common stock, $.01 par value per share. At the
time of the Acquisition, it was contemplated that the Acquisition would be
accounted for utilizing the pooling of interests method of accounting. As a
result of the Company's recent meeting and discussions with the Office of the
Chief Accountant ("OCA") of the Securities and Exchange Commission, the Company
will change the method of accounting for the Acquisition from the pooling of
interests method of accounting to the purchase method. After seeking input from
the OCA, the Company was informed that the OCA decided that the Company's
September 25, 1998 announcement regarding the action taken by its Board of
Directors on such date to authorize the repurchase of up to 3,000,000 shares of
its outstanding common stock constituted the form of announcement which the OCA
considers determinative that the Company had an intention to reacquire stock at
the time of the Acquisition. Although the Company had no such intention to
repurchase shares of its stock at the time of the Acquisition, the OCA
determined that the continued use of the pooling of interests treatment for the
Acquisition was unavailable. As a result, the Company's acquisition of BCSI,
which was completed on April 30, 1998, will be accounted for using the purchase
method of accounting rather than the pooling of interests method of accounting.
The Company's Form 10-Q for the quarterly period ended April 30, 1998,
originally filed on June 12, 1998, is being amended herein to reflect the change
in the method of accounting for the Acquisition.

NOTE A - DESCRIPTION OF ORGANIZATION AND BUSINESS

      ABR Information Services, Inc. (the "Company"), through its wholly-owned
subsidiaries, ABR Benefits Services, Inc., Charing Company, Inc., Matthews,
Malone & Associates, Ltd. and Business Computer Services, Inc., is a leading
provider of comprehensive benefits administration, payroll, and human resource
services to employers seeking to outsource these functions. The Company's
operating revenues currently are generated from three sources: employee health
and welfare administration services, qualified plan administration services,
and payroll and human resource administration services. All services are
offered on either an "a la carte" or a total outsourcing basis, allowing
customers to outsource certain benefits administration tasks which they find
too costly or burdensome to perform in-house, or to outsource the entire
benefits administration function. Additionally, the Company generates
non-operating revenue from the short-term lease of its St. Petersburg, Florida
operations center through its wholly-owned subsidiary, ABR Properties, Inc.

      The Company provides outsourced benefits administration, payroll, and
human resource services to more than 30,000 employers, ranging in size from 20
to 200,000 employees. ABR provides portability (COBRA and HIPAA) services
through the trade name CobraServ(R) and payroll and tax deposit services through
the trade name PayAmerica(R). The Company is headquartered in Palm Harbor,
Florida, and employs approximately 1,400 people in marketing/operations centers
in Florida, New Jersey, Virginia, Maryland, California, Wisconsin, and Arizona.

NOTE B - BASIS OF PRESENTATION

      The accompanying financial statements have been prepared in accordance
with the instructions to Form 10-Q and do not include all the information and
footnote disclosure required by generally accepted accounting principles for
complete financial statements. The financial statements as of April 30, 1998
and for the three and nine months ended April 30, 1998 and April 30, 1997 are
unaudited and reflect all adjustments (consisting only of normal recurring
adjustments) which are, in the opinion of management, necessary for a fair
presentation of the financial position and operating results for the interim
periods. The results of operations for the three and nine months ended April
30, 1998 are not necessarily indicative of results that may be expected for the
year ending July 31, 1998. These financial statements should be read in
conjunction with the audited financial statements of the Company as of July 31,
1996 and 1997, and for each of the three years in the period ended July 31,
1997, included in the Company's 1997 Annual Report to Shareholders.

      The Company presents Cash and Cash Equivalents exclusive of BCSI tax
deposits held for future payment on behalf of its payroll customers due to their
restricted and short-term nature. The amount of such tax deposits was
approximately $42.2 million at April 30, 1998.

      During fiscal 1998, the Company adopted Statement of Financial Accounting
Standard No. 128 "Earnings Per Share" (FAS 128). This Standard became effective
for financial statements issued after December 15, 1997 and eliminates primary
and fully diluted income per share and replaces them with basic and diluted
income per share. 




                                       6

Accordingly, all income per share amounts for the prior periods presented have
been restated to conform to the new Standard (see Note C).

NOTE C - NET INCOME PER COMMON SHARE

      The following table reconciles the numerators and denominators of the
basic and diluted income per share computations, as computed in accordance with
FAS 128:

NOTE D - COMMITMENTS

      On October 2, 1997, the Company acquired a 383,000 square foot office
campus in St. Petersburg, Florida for $13.5 million. The Company expects to
spend approximately $23 million to expand and renovate the facility over the
next three years. The Company expects to occupy portions of this facility
starting in calendar 1999. The former owner of the facility has signed a
short-term agreement to lease back portions of the campus, prior to the Company
occupying the entire facility in approximately the year 2000. The Company's
lease revenue on the campus is dependent upon the amount of square footage being
utilized by the former owner and is recorded net of the direct expenses of
operating the facility.

      The Company estimates that as of April 30, 1998, approximately $14.0
million will be required in order for the Company to purchase additional
equipment, furniture and hardware, and to complete currently defined software
projects.

NOTE E - BUSINESS ACQUISITIONS

      On December 15, 1995, the Company, in an acquisition accounted for as a
purchase, acquired all of the outstanding capital stock of Bullock Associates,
Inc. ("Bullock"), for $12.5 million, with an additional $2.0 million payable
upon the attainment of certain revenue requirements during 1996 and 1997.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


      The statements contained in the following discussion and analysis that
are not purely historical are forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. Such forward-looking statements involve a number of risks
and uncertainties and are based on information available to the Company on the
date hereof. The Company assumes no obligation to update any such
forward-looking statements.

      The following discussion and analysis should be read in conjunction with
the Financial Statements and notes thereto appearing elsewhere in this Form
10-Q.

OVERVIEW

      The Company's operating revenues currently are generated from three
sources: employee health and welfare administration services, qualified plan
administration services, and payroll and human resource administration
services. Additionally, the Company generates non-operating revenue from the
short-term lease of its St. Petersburg, Florida facility through its
wholly-owned subsidiary, ABR Properties, Inc.

      The first source of the Company's revenue is providing employee health
and welfare administration outsourcing services. In particular, the Company
provides portability (i.e., COBRA (the "Consolidated Omnibus Budget
Reconciliation Act"), HIPAA (the "Health Insurance Portability and
Accountability Act of 1996") or state-mandated continuation coverage, health
portability law) compliance services primarily through its qualifying event
agreements with employers and capitation agreements with insurance companies.
Through qualifying event agreements, the Company receives a fixed, per
occurrence, fee from its customers for each qualifying event. A qualifying
event occurs when an employee or his or her dependents experience a loss or
change of coverage under a group healthcare plan. The amount of the fixed fee
varies depending on the type of portability qualifying event and the method of
the qualifying event notification mailing, which is selected by the customer.
Through capitation agreements, insurance companies designate the Company as the
administrator of compliance for their group insurance clients that are subject
to health portability laws. The Company is paid a monthly fee for each employee
covered by the group plan. The revenue generated under a capitation agreement
is not dependent on the triggering of a qualifying event, but is determined
based on the number of employees covered by the group plan at the beginning of
each month. The Company also receives an administrative fee typically equal to
2% of the monthly health insurance premium that is paid by or on behalf of each
COBRA continuant. In addition, the Company generates health and welfare
administration services revenues by providing administration services for
benefits provided to active employees, including open enrollment, employee
enrollment and eligibility, and flexible spending account administration, along
with providing administration services for benefits provided to retired and
inactive employees, including retiree healthcare, disability, surviving
dependent, family leave and severance benefits. Most services are provided both
on a one-time or continuous basis. During the first nine months of fiscal 1997
and 1998, 97.0% and 92.7%, respectively, of the Company's revenues were
attributable to employee health and welfare administration services.

      The second source of the Company's revenue is providing employee
qualified plan administration services, including 401(k) plan administration,
profit sharing administration, defined benefit plan administration, ESOP
administration and Qualified Domestic Relations Order ("QDRO") administration.
During the first nine months of fiscal 1997 and 1998, 2.1% and 6.7%,
respectively, of the Company's revenues were attributable to employee qualified
retirement plans administration.

      The third source of the Company's revenue is providing payroll and human
resource administration services, including tax deposit services and integrated
human resource solutions. During the first nine months of fiscal 1997 and 1998,
0.9% and 0.6%, respectively, of the Company's revenues were attributable to
payroll and human resource administration services.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
          FINANCIAL CONDITION AND RESULTS OF OPERATIONS - (continued)

YEAR 2000 MATTERS

      The Year 2000 Issue is the result of computer programs being written
using two digits rather than four to define the applicable year. In 1996, the
Company initiated the process of modifying existing software programs to become
Year 2000 compliant. Management has determined that the Year 2000 issue will
not pose significant operational problems for its computer systems. As a
result, all costs associated with this conversion are being expensed as
incurred.

      The Company will utilize both internal and external resources to
reprogram, or replace, and test the software for Year 2000 modifications. The
Company anticipates completing the Year 2000 project no later than March 1999,
which is prior to any anticipated impact on its operating systems. The total
cost of the Year 2000 project is estimated at approximately $250,000 and is
being funded through operating cash flows and is not expected to have a
material effect on the results of operations.

      The cost of the project and the date on which the Company believes it
will complete the Year 2000 modifications are based on management's best
estimates, which were derived utilizing numerous assumptions of future events,
including the continued availability of certain resources, third party
modification plans and other factors. However, there can be no guarantee that
these estimates will be achieved and actual results could differ materially
from those anticipated. Specific factors that might cause such material
differences include, but are not limited to, the availability and cost of
personnel trained in this area, the ability to locate and correct all relevant
computer codes, and similar uncertainties.

      The Company has initiated formal communications with all of its
significant suppliers and large customers to determine the extent to which the
Company's interface systems are vulnerable to those third parties' failure to
remediate their own Year 2000 Issue. There can be no guarantee that the systems
of other companies on which the Company's systems rely will be timely converted
and would not have a material adverse effect on the Company's systems and in
turn, the Company's business, financial condition and results of operations.

RESULTS OF OPERATIONS

      The following table sets forth the percentage of revenue represented by
certain items reflected in the Company's statements of income.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
          FINANCIAL CONDITION AND RESULTS OF OPERATIONS - (continued)


THREE MONTHS ENDED APRIL 30, 1998 COMPARED TO THREE MONTHS ENDED APRIL 30, 1997

      Revenues increased $5.4 million, or 40.9%, to $18.6 million during the
three months ended April 30, 1998 from $13.2 million during the three months
ended April 30, 1997. Of the $5.4 million increase in revenues, $3.1 million
was attributable to increased employee health and welfare administration
revenues, $2.3 million was attributable to increased employee qualified plan
administration revenues. Payroll and human resource administration services
revenue was unchanged. For the quarter ended April 30, 1998, health and welfare
administration revenue was $15.9 million, qualified plan administration revenue
was $2.6 million, and payroll and human resource administration was $0.1
million.

      The increase in employee health and welfare administration revenues was
primarily attributable to the addition of new customers and new service product
offerings related to the federally-mandated HIPAA law. The increase in employee
qualified retirement plans administration revenues was primarily attributable
to the two new subsidiaries acquired by the Company effective February 1, 1998.

      Cost of services increased $3.3 million, or 44.6%, to $10.7 million
during the three months ended April 30, 1998 from $7.4 million during the three
months ended April 30, 1997. The increase in cost of services was attributable
to the addition of data processing, information systems and customer service
personnel to support revenue growth, the amortization of software placed in
service as completed, the transition and consolidation of certain operational
duties into the Florida operations center and the addition of two subsidiaries
during the quarter ended April 30, 1998. As a percentage of revenues, the 1998
cost of services increased to 57.7% from 55.9% in the previous year.

      Selling, general and administrative expenses increased $0.8 million, or
32.0%, to $3.3 million during the three months ended April 30, 1998 from $2.5
million during the three months ended April 30, 1997. The increase in selling,
general and administrative expenses was primarily attributable to the addition
of marketing, management and administrative personnel and equipment necessary
to support the Company's growth and the acquisition of two subsidiaries during
the quarter ended April 30, 1998. As a percentage of revenues, selling, general
and administrative expenses decreased to 18.0% from 19.3% in the previous year.

      Acquired research and development costs increased to $11.0 million from $0
in the prior period as a result of the purchase of BCSI on April 30,
1998. In accordance with applicable accounting standards, the purchased
in-process research and development of $11.0 million was expensed.

      Interest income decreased $.4 million to $1.2 million during the three
months ended April 30, 1998, from $1.6 million during the three months ended
April 30, 1997. This decrease was the result of less cash available for
investing due to capital purchases, cash payments for acquisitions of two new
subsidiaries, increased utilization of tax-free investment instruments which
yield a lower stated interest rate, and an overall decline in short-term
interest rates.

      Lease revenue increased to $.9 million for the three months ended April
30, 1998 as compared to $0 for the corresponding period in 1997 due to the
purchase of an office campus (with an existing tenant) in St. Petersburg,
Florida. Lease revenue is presented net of direct costs associated with
operating the campus. This net revenue will decrease as the Company begins to
occupy the campus in phases beginning in calendar 1999 and will decrease to $0
by April 1999, at the latest. Final occupancy by the Company is expected in
fiscal 2000.

      Income taxes increased 23.5% to $2.1 million during the three months
ended April 30, 1998 from $1.7 million during the three months ended April 30,
1997. The Company's effective tax rate increased to 147.5% for the three months
ended April 30, 1998, from 35.2% for the corresponding period in the previous
year. This increase was the result of the non-deductibility of acquired
in-process research and development costs associated with the BCSI
acquisition.

      As a result of the foregoing, the Company had a net loss of $6.4 million
during the three months ended April 30, 1998, as compared to net income of $3.2
million during the three months ended April 30, 1997. Basic and diluted net
loss per share was $.23 for the quarter ended April 30, 1998, as compared to
income per share of $.12 basic and $.11 diluted, respectively, for the
corresponding prior year period.

NINE MONTHS ENDED APRIL 30, 1998 COMPARED TO NINE MONTHS ENDED APRIL 30, 1997

      Revenues increased $15.3 million, or 43.3%, to $50.6 million during the
nine months ended April 30, 1998 from $35.3 million in the corresponding period
of 1997. Of the $15.3 million increase in revenues, $12.7 million was
attributable to increased employee health and welfare administration revenues,
$2.6 million was attributable to increased employee qualified plan
administration revenues. Payroll and human resource administration services
revenue was unchanged. For the nine months ended April 30, 1998, health and
welfare administration revenue was $46.9 million, qualified plan administration
revenue was $3.4 million and human resource administration revenue was $0.3
million.

      The increase in employee health and welfare administration revenues was
primarily attributable to the addition of new customers and new service product
offerings related to the federally-mandated HIPAA law. The increase in employee
qualified retirement plans administration revenues was primarily attributable
to the addition of two new subsidiaries acquired by the Company effective
February 1, 1998.

      Cost of services increased $9.0 million, or 45.2%, to $28.9 million
during the nine months ended April 30, 1998 from $19.9 million during the nine
months ended April 30, 1997. The increase in cost of services was attributable
to the addition of data processing, information systems and customer service
personnel to support revenue growth, the amortization of software placed in
service as completed, the transition and consolidation of certain operational
duties into the Florida operations center and the addition of two subsidiaries
during the quarter ended April 30, 1998. As a percentage of revenues, cost of
services increased to 57.2% from 56.4% for the corresponding period of 1997.

      Selling, general and administrative expenses increased $2.2 million, or
31.0%, to $9.3 million during the nine months ended April 30, 1998 from $7.1
million during the nine months ended April 30, 1997. As a percentage of
revenues, selling, general and administrative expense decreased to 18.4% during
the nine months ended April 30, 1998 from 20.0% during the nine months ended
April 30, 1997. The decrease as a percent of revenues resulted primarily from
allocating expenses over an increasingly larger revenue base.

      Acquired research and development increased to $11.0 million from $0 in
the prior period as a result of the purchase of BCSI on April 30, 1998.
In accordance with applicable accounting standards, the purchased in-process
research and development of $11.0 million was expensed.

      Interest income decreased $1.5 million to $4.0 million during the nine
months ended April 30, 1998 from $5.5 million during the nine months ended
April 30, 1997. This decrease was the result of less cash available for
investing due to capital purchases, cash payments for acquisitions of two new
subsidiaries, increased utilization of tax-free investment instruments which
yield a lower interest rate and an overall decline in short-term interest
rates.

      Lease revenue increased to $2.0 million during the nine months ended
April 30, 1998 as compared to $0 for the corresponding period in 1997 due to
the purchase of an office campus (with an existing tenant) in St. Petersburg,
Florida. Lease revenue is presented net of direct costs associated with
operating the campus. This net revenue will decrease as the Company begins to
occupy the campus in phases beginning in calendar 1999 and will decrease to $0
by April 1999, at the latest. Final occupancy by the Company is expected in
fiscal 2000.

      Income taxes increased 19.6% to $6.1 million during the nine months ended
April 30, 1998 from $5.1 million during the nine months ended April 30, 1997.
The Company's effective tax rate increased to 83.6% for the nine months ended
April 30, 1998 from 36.9% for the corresponding period in the previous year due
to the non-deductibility of acquired in-process research and development costs
associated with the BCSI acquisition.

      For the nine months ended April 30, 1998, net cash provided by operating
activities was $26.1 million as compared to $12.6 million for the corresponding
period of fiscal 1997. As of April 30, 1998 and July 31, 1997, the Company's
working capital and current ratio was $120.9 million and 4.3:1 and $127.8
million and 6.1:1, respectively. The Company invests excess cash balances in
short-term investment grade securities, such as money market investments,
obligations of the U.S. government and its agencies and obligations of state
and local government agencies.

      During the nine months ended April 30, 1998, the Company's capital
expenditures were $27.6 million.

      On October 2, 1997, the Company acquired a 383,000 square foot office
campus in St. Petersburg, Florida for $13.5 million. The Company expects to
spend approximately $23 million to expand and renovate the facility over the
next three years. Management estimates that as of April 30, 1998, approximately
$14.0 million will be required in order for the Company to purchase additional
equipment, furniture and hardware, and to complete its currently defined
software projects.

      The Company believes that its cash, investments, cash flows from
operations and potential additional borrowing capacity will be adequate to meet
the Company's expected capital requirements for the foreseeable future.
