                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                January 31, 1998


NOTE A - DESCRIPTION OF ORGANIZATION AND BUSINESS

     ABR Information Services, Inc. (the "Company") is a leading provider of
comprehensive benefits administration, compliance and information services to
employers seeking to outsource their benefits administration functions. The
Company believes it is the largest provider of COBRA (the "Consolidated Omnibus
Reconciliation Act") compliance services. COBRA is a federally mandated law
related to the portability of employee group health insurance. Additionally, the
Company provides compliance services related to the federally mandated Health
Insurance Portability and Accountability Act of 1996 ("HIPAA"). The Company
provides portability (COBRA and HIPAA) services through the trade name
CobraServSM.

     The Company also provides benefits administration services with respect to
benefits provided to retirees and inactive employees, including retiree
healthcare, disability, surviving dependent, family leave and severance
benefits. Additionally, the Company provides benefits administration services
with respect to benefits provided to active employees, including enrollment,
eligibility verification, qualified domestic relations order ("QDRO")
administration, 401(k) administration services, flexible spending account
("FSA") administration and pension 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.

     The Company provides information and support services to more than 25,000
employers, ranging in size from 2 to 200,000 employees, including approximately
100 of the Fortune 500 companies, insurance companies and other employers. The
Company is headquartered in Palm Harbor, Florida, and employs approximately
1,000 people in marketing/operations centers in Florida, New Jersey, Virginia
and California. The Company's operations are in a single business segment, the
information services business. Effective September 8, 1997, the Company
consolidated a number of its subsidiaries into one operating subsidiary called
ABR Benefits Services, Inc.

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 January 31, 1998
and for the three and six months ended January 31, 1998 and January 31, 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 six months ended January
31, 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.

      During the period ended January 31, 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. Accordingly, all income per share
amounts for the prior periods presented have been restated to conform to the new
Standard (see Note C).

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. Although no formal
construction commitments exist for this facility, the Company expects to spend
approximately $20 million to expand and renovate the facility over the next
three years. The Company expects to occupy portions of this facility starting in
calendar 1998. 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 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 January 31, 1998, approximately $9.1
million will be required in order for the Company to purchase additional
equipment, furniture and hardware, and to complete currently defined software
projects.

     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: portability compliance services, administration services with respect
to benefits provided to retirees and inactive employees, and administration
services with respect to benefits provided to active employees. Additionally,
the Company generates non-operating revenue from the short-term lease of its St.
Petersburg, Florida operations center.

     The first source of the Company's revenue is providing portability
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
qualifying event (i.e., COBRA (the "Consolidated Omnibus Budget Reconciliation
Act") or HIPAA (the "Health Insurance Portability and Accountability Act of
1996")) 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 COBRA, HIPAA or state mandated
continuation coverage 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 revenues
from customers for additional compliance and healthcare administration services,
both on a one-time and continuous basis. During the first six months of fiscal
1997 and 1998, 62.2% and 60.0%, respectively, of the Company's revenues were
attributable to portability compliance services.

     The second source of the Company's service revenue is providing
administration services with respect to benefits provided to retirees and
inactive employees, including retiree healthcare, disability, surviving
dependent, family leave and severance benefits. During the first six months of
fiscal 1997 and 1998, 16.0% and 11.6%, respectively, of the Company's revenues
were attributable to administration services for retirees and inactive
employees.

     The third source of the Company's service revenue is providing
administration services with respect to benefits provided to active employees,
including open enrollment, employee enrollment and eligibility, QDRO ("Qualified
Domestic Relations Order") administration, flexible spending account
administration, 401(k) plan administration, and other pension services. During
the first six months of fiscal 1997 and 1998, 21.8% and 28.4%, respectively, of
the Company's revenues were attributable to benefits administration services for
active employees.

                     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 $225,000 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 an adverse effect on the Company's systems.

THREE MONTHS ENDED JANUARY 31, 1998 COMPARED TO THREE MONTHS ENDED JANUARY 31,
1997

     Revenues increased $5.0 million, or 42.7%, to $16.7 million during the
three months ended January 31, 1998 from $11.7 million during the three months
ended January 31, 1997. Of the $5.0 million increase in revenues, $2.3 million
was attributable to increased revenues from portability compliance services,
$128,000 was attributable to increased revenues from retiree/inactive employee
benefits administration and $2.6 million was due to increased revenues from
active employee benefits administration.

<PAGE>   11




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


     The increase in portability compliance revenues was primarily attributable
to the addition of new customers and new service product offerings. New products
pertain to clients having to comply with state-mandated continuation coverage
health portability laws and the federally-mandated HIPAA law.

     The increase in active employee benefits administration revenues was
primarily attributable to the addition of new customers obtained by the Company
and new service product offerings in enrollment and eligibility administration
and qualified retirement plan services.

     Cost of services increased $2.9 million, or 42.8%, to $9.4 million during
the three months ended January 31, 1998 from $6.5 million during the three
months ended January 31, 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 and the transition and consolidation of certain operational
duties into the Florida operations center. As a percentage of revenues, the 1998
cost of services increased slightly to 56.0% from 55.9% in the previous year.

     Selling, general and administrative expenses increased $.9 million, or
39.9%, to $3.3 million during the three months ended January 31, 1998 from $2.4
million during the three months ended January 31, 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. As a percentage of revenues, selling, general and
administrative expenses decreased slightly to 19.8% from 20.2% for the
corresponding periods.

     Interest income decreased $.5 million to $1.4 million during the three
months ended January 31, 1998 from $1.9 million during the three months ended
January 31, 1997. This decrease was the result of less cash available for
investing due to capital purchases, 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 $1.1 million for the three months ended January
31, 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 1998 and will decrease to $0
by April 1999, at the latest. Final occupancy by the Company is expected in
2000.

     Income taxes increased 35.9% to $2.4 million during the three months ended
January 31, 1998 from $1.8 million during the three months ended January 31,
1997. The Company's effective tax rate decreased to 36.7% for the three months
ended January 31, 1998 from 37.6% for the corresponding period in the previous
year. This decrease reflected the Company's greater utilization of tax-free
investments.

     As a result of the foregoing, the Company's net income increased $1.2
million, or 41.4%, to $4.2 million during the three months ended January 31,
1998 from $2.9 million in the three months ended January 31, 1997. Basic and
diluted net income per share was $.15 for the quarter ended January 31, 1998 as
compared to $.11 (basic and diluted) for the corresponding prior year period,
after adjustment for the Company's 2-for-1 stock split in February 1997.

SIX MONTHS ENDED JANUARY 31, 1998 COMPARED TO SIX MONTHS ENDED JANUARY 31, 1997

     Revenues increased $9.8 million, or 44.5%, to $31.9 million in the six
months ended January 31, 1998 from $22.1 million in the corresponding period of
1997. Of the $9.8 million increase in revenues, $5.3 million was attributable to
increased revenues from portability compliance services, $166,000 was
attributable to increased revenues from retiree/inactive employee benefits
administration and $4.3 million was due to increased revenues from active
employee benefits administration.

     The increase in portability compliance revenues was primarily attributable
to the addition of new customers and new service product offerings. New products
pertain to clients having to comply with state-mandated continuation coverage
health portability laws and the federally-mandated HIPAA law.

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


     The increase in active employee benefits administration revenues was
primarily attributable to the addition of new customers obtained by the Company
and new service product offerings in enrollment and eligibility administration
and qualified retirement plan services.

     Cost of services increased $5.7 million, or 45.1%, to $18.2 million during
the six months ended January 31, 1998 from $12.5 million during the six months
ended January 31, 1997. As a percentage of revenues, cost of services increased
slightly to 56.9% from 56.7% for the corresponding period of 1997.

     Selling, general and administrative expenses increased $1.5 million, or
32.6%, to $6.0 million during the six months ended January 31, 1998 from $4.5
million during the six months ended January 31, 1997. As a percentage of service
revenues, selling, general and administrative expense decreased to 18.7% during
the six months ended January 31, 1998 from 20.4% during the six months ended
January 31, 1997. The decrease as a percent of revenues resulted primarily from
allocating expenses over an increasingly larger revenue base.

     Interest income decreased $1.1 million to $2.8 million during the six
months ended January 31, 1998 from $3.9 million during the six months ended
January 31, 1997. This decrease was the result of less cash available for
investing due to capital purchases, 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 $1.1 million during the six months ended January
31, 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 1998 and will decrease to $0
by April 1999, at the latest. Final occupancy by the Company is expected in
2000.

     Income taxes increased 20.3% to $4.1 million during the six months ended
January 31, 1998 from $3.4 million during the six months ended January 31, 1997.
The Company's effective tax rate decreased to 34.7%, for the six months ended
January 31, 1998 from 37.9% for the corresponding period in the previous year
primarily due to greater utilization of tax-free investments.

     As a result of the foregoing, the Company's net income increased $2.1
million, or 37.9%, to $7.7 million during the six months ended January 31, 1998
from $5.6 million during the six months ended January 31, 1997. Basic and
diluted net income per share were $.28 and $.27, respectively, for the six
months ended January 31, 1998 as compared to $.20 (basic and diluted) for the
corresponding prior year period after adjustment for the Company's 2-for-1 stock
split in February 1997.

LIQUIDITY AND CAPITAL RESOURCES

     For the six months ended January 31, 1998, net cash provided by operating
activities was $15.5 million as compared to $6.9 million for the corresponding
period of fiscal 1997. As of January 31, 1998 and July 31, 1997, the Company's
working capital and current ratio were $125.8 million and 5.2-to-1 and $127.8
million and 6.1-to-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 six months ended January 31, 1998, the Company's capital
expenditures were $23.5 million.

     On October 2, 1997, the Company acquired a 383,000 square foot office
campus in St. Petersburg, Florida for $13.5 million. Although no formal
construction commitments exist for this facility, the Company expects to spend
approximately $20 million to expand and renovate the facility over the next
three years. Management estimates that as of January 31, 1998, approximately
$9.1 million will be required in order for the Company to purchase additional
equipment, furniture and hardware, and to complete its currently defined
software projects.

<PAGE>   13



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


     The Company has a two-year, $15.0 million unsecured credit facility with a
financial institution. The Company has agreed to maintain all of its assets free
and clear of all liens, encumbrances and pledges, except purchase money security
interests in specific equipment in an aggregate amount of less than $500,000 as
long as the credit facility remains outstanding or any indebtedness thereunder
remains unpaid. Interest on the principal balance outstanding under this line of
credit accrues at a floating interest rate equal to the prime rate or, at the
Company's option, to the 30-day London Interbank Offering Rate (LIBOR), plus an
applicable interest rate margin between 1% and 2% based on certain financial
ratios. The credit facility contains certain financial covenants requiring the
maintenance of cash and cash equivalents and investments equal to or greater
than customer account deposits, a funded debt to earnings before interest,
taxes, depreciation and amortization (EBITDA) ratio of a maximum of 2.25-to-1, a
debt service coverage ratio of not less than 1.35-to-1, as well as the
maintenance of certain funded debt to tangible net worth ratio. As of January
31, 1998, the Company was in compliance with all such covenants and there were
no amounts outstanding under the credit facility. This facility expires in March
1998. The Company presently intends to renew and increase the amount of the
facility, although no assurance can be given that the Company can or will do so.

     The Company believes that its cash, investments, cash flows from operations
and funds available from its credit facility will be adequate to meet the
Company's expected capital requirements for the foreseeable future.
