                         CATALINA MARKETING CORPORATION
              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, 1998 and March 31, 1998, and the results
of operations and cash flows for the three month periods ended June 30, 1998
and 1997.

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 owned foreign subsidiaries are included as
of and for the three month periods ended March 31, 1998 and 1997. All material
intercompany profits, transactions and balances have been eliminated. The
Company's investment in a non-majority owned company is accounted for on the
equity method.

These financial statements, including the condensed consolidated balance sheet
as of March 31, 1998, 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, 1998.

The following is a reconciliation of the denominator of basic EPS to the
denominator of diluted EPS (in thousands):

Options to purchase 553,710 shares of common stock at prices ranging from
$51.31 to $53.50 per share were outstanding at June 30, 1998, 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.

No. 130, "Reporting Comprehensive Income" (SFAS No. 130) and accordingly,

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

FISCAL 1999 COMPARED TO FISCAL 1998

The Company's revenues for the first quarter of fiscal 1999 increased 22
percent, compared with the same period in fiscal 1998. The increase in revenues
is primarily due to growth in new programs such as Checkout Direct(R). Catalina
Marketing Services, constituting the Company's base business in the U.S.,
contributed approximately $46.7 million of revenues in the first quarter of
fiscal 1999, up 17 percent over revenues of $40.0 million in the comparable
fiscal 1998 period.

In the U.S., the Catalina Marketing Network was in 11,432 stores at June 30,
1998, which reach 153 million shoppers each week as compared to 10,832 stores
reaching 147 million shoppers each week at June 30, 1997 and 11,164 stores
reaching 143 million shoppers each week at March 31, 1998. The Health Resources
Network was in 2,256 pharmacies at June 30, 1998 as compared to 1,394
pharmacies at June 30, 1997 and 1,920 pharmacies at March 31, 1998. Outside the
U.S., the Catalina Marketing Network was in 1,456 stores at June 30, 1998,
which reach 23 million shoppers each week as compared to 1,057 stores reaching
20 million shoppers each week at June 30, 1997 and 1,372 stores reaching 20
million shoppers each week at March 31, 1998.

In the first quarter of fiscal 1999 the Company installed its Catalina
Marketing Network in 268 stores (net of deinstallations) in the U.S. as
compared to 87 stores in the comparable fiscal 1998 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
Resources Network in 336 pharmacies (net of deinstallations) in the first
quarter of fiscal 1999 as compared to 199 stores in the comparable fiscal 1998
period. Outside the U.S., the Company installed 84 stores (net of
deinstallations) in the first quarter of fiscal 1999 as compared to 116 stores
in the comparable fiscal 1998 period.

Direct operating expenses consist of retailer fees, paper, sales commissions
and the expenses of operating and maintaining the Catalina Marketing Network
(primarily expenses relating to operations personnel and service offices),
provision for doubtful accounts and the direct expenses associated with
operating the outdoor media business in a majority-owned subsidiary in Japan.
Direct operating expenses increased in absolute terms to $23.6 million for the
first quarter of fiscal 1999 from $18.0 million in the comparable period of
fiscal 1998. Direct operating expenses in the first quarter of fiscal 1999 as a
percentage of revenues increased to 41.4 percent from 38.6 percent in the
comparable period of fiscal 1998. This increase in fiscal 1999 is principally
attributable to the Company's increase in loyalty marketing programs which by
their nature have a higher percentage of direct costs to revenue than the
Company's other base business products.





                                       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 1999 were $15.3 million, compared to $12.9 million for the comparable
period of fiscal 1998, an increase of 18.7 percent or $2.4 million. The
increase relates primarily to higher costs associated with a larger sales
force, and administrative expenses of new business ventures and products. As a
percentage of revenues, selling, general and administrative expenses in the
first quarter of fiscal 1999 decreased to 26.9 percent from 27.6 percent for
the comparable period of fiscal 1998. This decrease is attributable to fiscal
1999 savings related to the closure of the Company's operations in Mexico in
the second quarter of fiscal 1998.

Depreciation and amortization increased to $6.4 million for the first quarter
of fiscal 1999 from $5.7 million for the comparable period in fiscal 1998.
Depreciation increased due to the investment in capital expenditures associated
with new business ventures and data processing equipment and the increase in
stores installed.

Interest expense and other decreased to $28,000 for the first quarter of fiscal
1999 from $393,000 for the comparable period in fiscal 1998. The decrease is
primarily due to the Company incurring interest expense on borrowings from its
credit facility for the repurchase of $40 million of its common stock in the
first quarter of fiscal 1998.

The provision for income taxes increased to $4.8 million (41.6 percent of
income before income taxes) for the first quarter of fiscal 1999, compared to
$4.0 million (41.6 percent of income before income taxes) for the same period
in fiscal 1998. The Company's effective tax rate is higher than the expected
federal statutory tax rate due to state and foreign income taxes and the
inability to currently utilize losses of majority owned foreign subsidiaries
for tax purposes.


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 $5,000 to $13,000 per store.
During the first quarter of fiscal 1999 and 1998, the Company made capital
expenditures of $8.2 million and $3.5 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 1999, the Company had a faster pace of U.S. store
installations and spent $1.9 million more in data processing equipment and
furniture and fixtures compared to the comparable fiscal 1998 period.
Management believes that expenditures for capital equipment will remain between
$20 and $35 million annually for the foreseeable future.






                                       9

In July 1998, the Company acquired Market Logic, a full service targeted
marketing organization that specializes in the development and fulfillment of
highly sophisticated, personalized direct marketing programs for retailers. In
July 1998, the Company made a $2.9 million payment in accordance with terms of
the purchase agreement for Market Logic. The agreement calls for the Company to
make a series of four additional annual cash payments, which are contingent
upon the financial performance of Market Logic for the fiscal 1999, 2000, 2001
and 2002 calendar years.

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

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 and
will be completed in fiscal 1999 and includes spending of approximately $1.0
million for testing and upgrading hardware and software. The Company believes
that it will be Year 2000 compliant without a material impact on its operations
or financial results.
