              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

Note 1. Condensed Consolidated Financial Statements:

In the opinion of the Company, the accompanying unaudited condensed
consolidated financial statements reflect all adjustments (consisting only of
normal recurring adjustments) necessary to present fairly the financial
position of the Company as of June 30, 1999 and March 31, 1999, and the results
of operations and cash flows for the three month periods ended June 30, 1999
and 1998. Certain prior balances have been reclassified to conform with the
current year presentation.

The condensed consolidated financial statements include the accounts of the
Company and its wholly-owned and majority-owned subsidiaries. The first quarter
balances and results of the majority and wholly owned foreign subsidiaries are
included as of March 31, 1999 and December 31, 1998 and for the three month
periods ended March 31, 1999 and 1998, respectively. All material intercompany
profits, transactions and balances have been eliminated.

These financial statements, including the condensed consolidated balance sheet
as of March 31, 1999, which has been derived from audited financial statements,
are presented in accordance with the requirements of Form 10-Q and consequently
may not include all disclosures normally required by generally accepted
accounting principles or those normally made in the Company's Annual Report on
Form 10-K. The accompanying condensed consolidated financial statements and
related notes should be read in conjunction with the Company's Annual Report on
Form 10-K for the fiscal year ended March 31, 1999.

Options to purchase 90,000 shares of common stock at a $91.25 exercise price
per share were outstanding at June 30, 1999, but were not included in the
computation of diluted EPS because the options' exercise prices were greater
than the average market price of common stock.

Note 4. Convertible Long Term Debt:

Effective April 5, 1999, the Tribune Company, an unrelated entity, made an
investment in Supermarkets Online, a majority owned subsidiary of the Company.
In addition to this equity investment, Supermarkets Online borrowed $1.4

note bearing interest at a rate of 4.5 percent per annum. This long term debt
obligation is convertible into 500,000 shares of Supermarkets Online common
stock upon certain occurrences.


Note 5. Acquisition:

Effective April 21, 1999, the Company, through one of its wholly owned
subsidiaries, acquired one of its vendors, CompuScan Marketing, Inc.
("Compuscan"), for $9.1 million in initial cash consideration, net of cash
acquired, by means of a merger transaction. Compuscan provides the intellectual
property and backroom processing for the Company's Checkout Prizes product.
Terms of the merger agreement call for the Company to make a series of
additional payments, which are based on specified future revenue growth targets
of the Checkout Prizes product. The purchase has been accounted for using the

ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS:

FISCAL 2000 COMPARED TO FISCAL 1999

The Company's revenues for the first quarter of fiscal 2000 increased 27.8
percent, compared with the same period in fiscal 1999. The increase in revenues
is due to an increase in promotions printed worldwide, increases in direct mail
marketing programs and growth in the Checkout Direct(R) program. Direct mail
marketing programs include, among others, the revenues added by the acquisition
of Market Logic, which was completed on July 13, 1998.

In the U.S., the Catalina Marketing Network was in 12,257 stores at June 30,
1999, which reach 161 million shoppers each week as compared to 11,432 stores
reaching 153 million shoppers each week at June 30, 1998 and 12,092 stores
reaching 152 million shoppers each week at March 31, 1999. The Health Resource
Network was in 4,152 pharmacies at June 30, 1999 as compared to 2,256
pharmacies at June 30, 1998 and 3,861 pharmacies at March 31, 1999. Outside the
U.S., the Catalina Marketing Network was in 2,249 stores at June 30, 1999,
which reach 33 million shoppers each week as compared to 1,456 stores reaching
23 million shoppers each week at June 30, 1998 and 1,935 stores reaching 29
million shoppers each week at March 31, 1999.

In the first quarter of fiscal 2000 the Company installed its Catalina
Marketing Network in 165 stores in the U.S., net of deinstallations, as
compared to 268 stores in the comparable fiscal 1999 period. Deinstallation
activity can and does occur primarily due to the consolidation and business
combination of supermarket chains as well as store closures made by retailers
in the ordinary course of business. The Company also installed its Health
Resource Network in 291 pharmacies in the first quarter of fiscal 2000, net of
deinstallations, as compared to 336 stores in the comparable fiscal 1999
period. Outside the U.S., the Company installed 314 stores in the first quarter
of fiscal 2000, net of deinstallations, as compared to 84 stores in the
comparable fiscal 1999 period.

Direct operating expenses consist of retailer fees; paper; sales commissions;
loyalty and direct marketing expenses; provision for doubtful accounts; the
expenses of operating and maintaining the Catalina Marketing and Health
Resource Network, primarily expenses relating to operations personnel and
service offices, and the direct expenses associated with operating the outdoor
media business in a majority-owned subsidiary in Asia. Direct operating
expenses increased in absolute terms to $30.2 million for the first quarter of
fiscal 2000 from $23.6 million in the comparable period of fiscal 1999. Direct
operating expenses in the first quarter of fiscal 2000 as a percentage of
revenues increased to 41.5 percent from 41.4 percent in the comparable period
of fiscal 1999. This increase in fiscal 2000 is principally attributable to the
Company's increase in loyalty and direct marketing programs, including the
Market Logic and DCI Cardmarketing businesses, which by their nature have a
higher material cost component of direct costs as a function of revenue than
the Company's other core product line services.

                                       8

<PAGE>   9

Selling, general and administrative expenses include personnel-related costs of
selling and administrative staff, overhead and new product development
expenses. Selling, general and administrative expenses for the first quarter of
fiscal 2000 were $19.8 million, compared to $15.3 million for the comparable
period of fiscal 1999, an increase of 29.4 percent or $4.5 million. As a
percentage of revenues, selling, general and administrative expenses increased
0.4 percent in the first quarter of fiscal 2000, to 27.3 percent from 26.9
percent for the comparable period of fiscal 1999. The increase relates
primarily to administrative expenses relating to new operating units and
products.

Depreciation and amortization increased to $8.2 million for the first quarter
of fiscal 2000 from $6.4 million for the comparable period in fiscal 1999.
Depreciation increased due to the investment in capital expenditures, during
the current and prior periods, associated with new operating units and product
lines, data processing equipment and the increase in stores installed.
Amortization expense increased due to the increases in goodwill and other
intangible assets related to the Company's acquisitions.

Interest expense, net and other increased to $201,000 net expense for the first
quarter of fiscal 2000 from $28,000 net expense for the comparable period in
fiscal 1999. This increase in net expense is primarily attributable to lower
average cash balances available for investment and lower interest rates in the
first quarter of fiscal 2000 than in the comparable period in fiscal 1999 and
increased short term borrowing balances in the Company's Asian subsidiary
reported as of June 30, 1999 as compared to June 30, 1998.

The provision for income taxes increased to $5.7 million, or 40.2 percent of
income before income taxes and minority interest, for the first quarter of
fiscal 2000, compared to $4.8 million, or 41.6 percent of income before income
taxes and minority interest, for the same period in fiscal 1999. The rate
decrease is primarily due to the Company's ability to utilize losses of a
majority owned foreign subsidiary for income tax purposes in fiscal 2000. The
Company's effective tax rate is higher than the federal statutory income tax
rate due to state and foreign income taxes and various nondeductible expenses,
primarily the amortization of goodwill related to the Company's acquisitions.

LIQUIDITY AND CAPITAL RESOURCES

The Company's primary capital expenditures are store equipment and third-party
store installation costs, as well as data processing equipment for the
Company's central data processing facilities. Total store equipment and
third-party store installation costs range from $3,000 to $13,000 per store.
During the first quarters of fiscal 2000 and 1999, the Company made capital
expenditures of $12.0 million and $8.2 million, respectively. The pace of
installations varies depending on the timing of contracts entered into with
retailers and the scheduling of store installations by mutual agreement. During
the first quarter of fiscal 2000, the Company spent $3.6 million more on store
equipment compared to the comparable fiscal 1999 period.

 Effective April 21, 1999, the Company, through one of its wholly owned
subsidiaries, acquired one of its vendors, CompuScan, for $9.1 million in
initial cash consideration, net of cash acquired, by means of a merger
transaction. Terms of the merger agreement call for the Company to make a series
of additional payments, which are based on specified future revenue growth
targets of the Checkout Prizes product. Additionally, in the first quarter of
fiscal 2000, investments were made totaling $8.9 million which were comprised of
earnout payments attributable to past acquisitions.

The Company believes working capital generated by operations along with
existing credit facilities are sufficient for its overall capital requirements.

Other

Year 2000 Readiness Disclosure

This year 2000 disclosure is the most current information available and
replaces all previous disclosures made by the Company in its filings on Form
10-Q and Form 10-K, and in its Annual Report to Stockholders.

In the next year, many companies will face potentially serious risks associated
with the inability of existing business systems to appropriately recognize
calendar dates beginning in the year 2000. The Company is aware of the year
2000 issue and the effects it may have on its business systems. In response,
the Company has developed a detailed plan to address the issue. This plan
includes a campaign which began in fiscal 1998, was revised to consider
acquired companies' business systems, and has a goal for completion in October
1999. The plan currently includes spending of approximately $1.6 million for
testing and upgrading hardware and software. The Company has spent
approximately $1.1 million on the year 2000 issue through June 30, 1999.
Progress towards completion of the plan is within management's expectations to
meet the October 1999 goal.

The Company has contacted substantially all of its hardware and software
vendors, suppliers and financial institution partners to evaluate their
compliance efforts. Those that have been deemed noncompliant have been
evaluated and corrective action has been or will be taken by October 1999 to
ensure the vendors' year 2000 efforts or lack there of will not adversely
impact the Company's operations.

The Company's manufacturer clients and retailers may also encounter year 2000
issues and are in various states of readiness. If these manufacturers or
retailers encounter serious problems related to the year 2000 issue, those
problems could have a material adverse impact on the operations of the Company.
The Company believes most of its manufacturer clients and retailers are
addressing the year 2000 issue, and the Company is closely monitoring the status
of their readiness.

In the event that the Company's year 2000 compliance efforts are unsuccessful
and/or one or more of the Company's critical internal systems are not year 2000
compliant by December 31, 1999, the following could occur, any of which could
have a material adverse impact on the operations of the Company:

(a) Customer service could deteriorate to the point that a substantial number
    of the Company's customers move their relationships to other organizations;
(b) The Company may be unable to provide manufacturer and retail clients with
    timely and accurate information about program execution; or
(c) The Company may be unable to fulfill various contractual obligations

The Company believes substantially all of its internally developed applications
and purchased applications used internally will be year 2000 compliant by
October 1999. The Company has therefore focused its efforts on contingency
planning for business systems outside of those applications, as warranted.
