              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


NOTE 1 - BASIS OF PRESENTATION

       Principles of consolidation: The condensed consolidated financial
statements include the accounts of Information Resources, Inc. and all
wholly or majority owned subsidiaries and affiliates (collectively "the
Company"). Minority interests reflect the non-Company owned stockholder
interests in international operations. The equity method of accounting is
used for investments in which the Company has a 20% to 50% ownership
interest because it exercises significant influence over operating and
financial policies. All significant intercompany accounts and
transactions have been eliminated in consolidation.

       Interim financial statements: The interim financial statements are
unaudited, but include all adjustments (consisting of normal recurring
adjustments) necessary, in the opinion of management, for a fair
statement of financial position and results of operations for the period
presented. The preparation of interim financial statements necessarily
relies on estimates, requiring the use of caution in estimating results
for the full year based on interim results of operations.

       Reclassifications:  Certain amounts in the 1999 condensed consolidated
financial  statements have been reclassified to conform to the 2000
presentation.

       Earnings (Loss) per Common and Common Equivalent Share: Net
earnings (loss) per share is based upon the weighted average number of
shares of common stock outstanding during each period. Net earnings
(loss) per common and common equivalent share-diluted is based upon the
weighted average number of shares of common stock and common stock
equivalents, entirely comprised of stock options, outstanding during each
period. In 2000, common stock equivalents were excluded from the weighted
average shares outstanding calculation because they were anti-dilutive.

NOTE 2 - SUPPLEMENTAL CASH FLOW INFORMATION

       Cash paid (received) for interest and income taxes during the
period was as follows (in thousands):

                                                     SIX MONTHS ENDED

                                                      ----       ----

Income taxes                                          (356)       229

       Non-cash investing and financing activities are excluded from the
consolidated statement of cash flows. During the six months ended June
30, 2000, the Company acquired mainframe computer equipment in exchange
for a capital lease obligation recorded at $5.6 million. The Company
repaid a portion of the capital lease obligation during the second
quarter of 2000.

       The financial covenants in the bank credit agreement, as well as
in the lease agreement for the Company's Chicago headquarters, require
the Company to maintain a minimum tangible net worth and to meet certain
cash flow coverage and leverage ratios. The agreements also limit the
Company's ability to declare dividends or make distributions to holders
of capital stock, or redeem or otherwise acquire shares of the Company.
Approximately $8.4 million is currently available for such distributions
under the most restrictive of these covenants. The bank credit agreement
contains covenants which restrict the Company's ability to incur
additional indebtedness.

NOTE 7 - COMMITMENTS, CONTINGENCIES AND LITIGATION

       On July 29, 1996, IRI filed an action against The Dun & Bradstreet Corp.,
The A.C. Nielsen Company (now a subsidiary of ACNielsen) and IMS International,
Inc. (collectively, "the Defendants") in the United States District Court for
the Southern District of New York entitled Information Resources, Inc. v. The
Dun & Bradstreet Corp., et. al. No. 96 CIV. 5716 (the "Action"). IRI alleged
that, among other things, the Defendants violated Sections 1 and 2 of the
Sherman Act, 15 U.S.C. Sections 1 and 2, by engaging in a series of
anti-competitive practices aimed at excluding the Company from various export
markets for retail tracking services and regaining monopoly power in the United
States market for such services. By the Action, the Company seeks to enjoin the
Defendants' anti-competitive practices and to recover damages in excess of
$350.0 million, prior to trebling. The Action is more particularly described in
the Company's Annual Report on Form 10-K for the fiscal year ended December 31,
1999. On July 13, 2000, the District Court in a procedural ruling held that IRI
lacked standing to assert claims for injury suffered from Defendants' activities
in foreign markets where IRI operates through subsidiaries or companies owned by
joint ventures and dismissed such claims. The District Court left open the issue
of whether those subsidiaries and joint ventures could sue in the United States
for injury suffered from Defendants' activities in the foreign markets where
they operate.

NOTE 8 - SEGMENT INFORMATION

       The Company's business information services are conducted almost
exclusively in the United States and Europe. The Company's operations in
other markets account for approximately 1% of consolidated revenues. The
executive management of the Company considers revenues from third parties
and the aggregation of operating profit (loss), equity earnings (losses)
and minority interests, ("Operating Results"), on a geographic basis to be
the most meaningful measure of the operating performance of each respective
geographic segment and of the Company as a whole.

NOTE 9 - RESTRUCTURING AND OTHER CHARGES

RESTRUCTURING

         In the third quarter of 1999, the Company initiated a
comprehensive cost reduction program named Project Delta. The first phase
of Project Delta included the identification and assessment of potential
operating efficiencies in the Company's various U.S. functional areas and
was completed in the fourth quarter of 1999. The cost reduction program
implementation began in the first quarter of 2000, with cost savings of
approximately $6.0 million to $8.0 million achieved year to date.

         Certain restructuring costs were not eligible for accrual in 1999
and were recorded in the first two quarters of 2000. For the quarter and
year to date June 30, 2000, the restructuring charges included in
Restructuring and Other Charges in the Statement of Operations consist of
the following (in thousands):

</TABLE>

         Termination Benefits: In the fourth quarter of 1999, the Company
expected to terminate 325 full-time positions during 2000 impacting
virtually all areas of the U.S. business, including operations, client
services, technology and marketing, as well as Corporate headquarters. As
of June 30, 2000, $4.1 million of accrued termination benefits have been
disbursed and 152 employees have been terminated under various Project
Delta initiatives. Additional provisions have been made throughout the year
to cover retention and relocation incentive costs that were not eligible
for accrual at December 31, 1999.

         Disposition of Excess Office Space: As a result of planned
headcount reductions and space not currently utilized, the Company has
decided to vacate certain facilities. The Company recorded $.6 million of
charges relating to accelerated depreciation on leasehold improvements and
furniture and fixtures and $.2 million in lease buyouts associated with
these facilities in the first half of 2000.

         Transition of German Production to U.S. Facility: The Company made
a decision in the fourth quarter of 1999 to transfer production services
for IRI/GfK Retail Services GmbH from an external vendor in Germany to the
Company's U.S. headquarter facility in order to enhance its InfoScan
offering in Germany and to reduce future production costs. In the first
half of 2000, charges of approximately $2.2 million were recorded related
to this transition.

         Other Restructuring Costs: Other restructuring costs relate
primarily to the final fees paid to the Boston Consulting Group for
assistance in the identification and execution of the Project Delta
objectives.

OTHER CHARGES

         In the fourth quarter of 1999, Restructuring and Other Charges
included a $.9 million charge for a non-current receivables reserve. This
reserve was reversed in the second quarter of 2000 pursuant to a settlement
agreement reached with the other party.

                  INFORMATION RESOURCES, INC. AND SUBSIDIARIES
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


          The following narrative discusses the results of operations,
 liquidity and capital resources for the Company on a consolidated basis.
 This section should be read in conjunction with IRI's Annual Report on Form
 10-K for the fiscal year ended December 31, 1999. See "Management's
 Discussion and Analysis of Financial Condition and Results of Operations"
 contained therein.

 RESULTS OF OPERATIONS

          The Company's consolidated net loss was $1.0 million or $.03 per
 diluted share for the second quarter of 2000 compared to consolidated net
 income of $.5 million or $.02 per diluted share for the corresponding 1999
 quarter. The Company's consolidated net loss was $4.5 million or $.16 per
 diluted share for the six months ended June 30, 2000 compared to
 consolidated net income of $.2 million or $.01 per diluted share for the
 corresponding 1999 period. Excluding restructuring and other charges, net
 income (loss) for the quarter and year to date 2000 was $.3 million and
 ($1.2) million, respectively, or $.01 and ($.04) per diluted share.

 Second Quarter Versus Prior Year

          Consolidated revenues for the quarter ended June 30, 2000 were
 $133.9 million, a decrease of 3% over the corresponding quarter in 1999.
 U.S revenues were $101.4 million, a decrease of 4% compared to the prior
 year due to the delayed financial impact of client losses experienced in
 1999. International revenues increased 1% to $32.5 million. Excluding
 foreign exchange effects, European revenues for the second quarter
 increased 13% over the prior year reflecting continued strong revenue
 growth in each of the major European businesses.

          Consolidated costs of information services sold decreased 4% to
 $119.2 million for the three months ended June 30, 2000 compared to costs
 of $124.3 million for the second quarter of 1999. The decline in expenses
 resulted primarily from the Company's cost reduction initiative, Project
 Delta, and the continued strengthening of the U.S. dollar against European
 currencies. These savings were offset slightly by increased costs related
 to the investment in the Company's CPGNetwork internet-based delivery
 service and other strategic opportunities.

          Consolidated selling, general and administrative expenses
 increased 9% to $14.3 million for the three months ended June 30, 2000
 compared to $13.1 million for the second quarter of 1999. The increase was
 primarily due to costs incurred during 2000 to pursue new strategic
 opportunities for the Company, including internet-based business
 initiatives.

            OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, CONT'D.



         Operating income, before restructuring and other charges of $2.1
million, was $1.2 million for the second quarter of 2000 compared to $1.4
million in the prior year. Improvements in the performance of the
international operations and reduced U.S. expenses offset the decline in
U.S. revenues resulting from 1999 client losses.

         Restructuring and other charges are discussed below. Interest and
other expenses were $.7 million for the second quarter of 2000 compared to
$.4 million in the prior year due to higher bank borrowings during 2000.

First Half Versus Prior Year

         Consolidated revenues were $263.1 million for the six months ended
June 30, 2000, a decrease of 2% over the corresponding period of 1999. U.S.
business revenues decreased 4% to $199.8 million for the first half of 2000
compared to the prior year. The decline was due to the delayed financial
impact on the current period's revenues of 1999 client losses.
International revenues were up 3% to $63.3 million over the first half of
1999. Excluding the impact of foreign exchange rates, European revenues for
the first half of 2000 increased 14% over the prior year.

         Consolidated costs of information services sold decreased 3% to
$238.8 million for the six months ended June 30, 2000 compared to costs of
$245.0 million for the first half of 1999. Expenses declined primarily due
to savings achieved through the Project Delta cost reduction initiative and
the continued strengthening of the U.S. dollar against European currencies.
These savings were offset slightly by increased costs related to the
investment in the Company's CPGNetwork internet-based delivery service and
other strategic opportunities.

         Consolidated selling, general and administrative expenses
increased 5% to $27.2 million for the six months ended June 30, 2000
compared to $25.9 million for the first half of 1999. The increase is
primarily attributable to the costs incurred during 2000 to pursue new
strategic opportunities for the Company, including internet-based business
initiatives.

         For the first half of 2000, the Company's operating loss, before
restructuring and other charges of $5.6 million, was $.9 million compared
to operating income of $1.0 million in the prior year. Results were below
prior year because of the delayed financial impact of 1999 U.S. client
losses on revenues partially offset by improved international performance
and reduced U.S. expenses resulting from the Company's Project Delta cost
reduction initiatives.

            OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, CONT'D.


         Restructuring and other charges are discussed below. Interest and
other expenses were $1.5 million for the six months ended June 30, 2000
compared to $.6 million in the prior year due to higher bank borrowings
during the first half of 2000. The Company's effective income tax rate is
greater than the U.S. Federal statutory rate due to certain unbenefited
foreign losses, goodwill amortization and other nondeductible expenses.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's current cash resources include its $4.9 million
consolidated cash balance and $31.3 million available under the Company's
bank revolving credit facility. The Company anticipates that it will have
sufficient funds from these sources and internally generated funds from its
U.S. operations to satisfy its cash needs for the foreseeable future.

Financings

  The financial covenants in the bank credit agreement, as well as in the
lease agreement for the Company's Chicago headquarters, require the Company
to maintain a minimum tangible net worth and to meet certain cash flow
coverage and leverage ratios. The agreements also limit the Company's
ability to declare dividends or make distributions to holders of capital
stock, or redeem or otherwise acquire shares of the Company. Approximately
$8.4 million is currently available for such distributions under the most
restrictive of these covenants. The bank credit agreement also contains
covenants that restrict the Company's ability to incur additional
indebtedness.

Cash Flow

         Consolidated net cash provided by operating activities was $53.6
million for the six months ended June 30, 2000 compared to $73.9 million
for the same period in 1999. This reduction was primarily attributable to
lower earnings resulting from restructuring charges and timing of payments
of accounts payable and accrued liabilities. Consolidated cash flow used in
net investing activities was $72.4 million in 2000 compared to $80.1
million for the same period in 1999. Net cash used before financing
activities was $18.8 million for the six months ended June 30, 2000
compared to $6.2 million for the same period in 1999. Consolidated cash
flow provided by financing activities reflects borrowings of $17.6 million
under its revolving line of credit in 2000 compared to $8.8 million in the
prior year.

Other Deferred Costs and Capital Expenditures

         Consolidated deferred data procurement expenditures were $63.7
million for the six months ended June 30, 2000 and $64.5 million for the
same period in 1999. These expenditures are amortized over a period of 28
months and include payments and services to retailers for point-of-sale
data and other costs related to collecting, reviewing and verifying panel,
causal and other data which are an essential part of the Company's
database. Such expenditures were $36.6 million and $40.2 million for the
periods ended June 30, 2000 and 1999, respectively, for the Company's U.S.
services business and $27.1 million and $24.3 million, respectively, for
the Company's International services business.

         Consolidated capital expenditures were $7.8 million and $15.1
million for the six months ended June 30, 2000 and 1999, respectively.
Capital expenditures for the Company's U.S. services business were $5.5
million and $13.0 million, while depreciation expense was $12.5 million and
$10.7 million for the six months ended June 30, 2000 and 1999,
respectively. During the first half of 2000, the Company acquired mainframe
computer equipment in exchange for a capital lease obligation recorded at
$5.6 million. The Company's International services business capital
expenditures were $2.3 million and $2.1 million for the six months ended
June 30, 2000 and 1999, respectively, while depreciation expense was $2.3
million for the first half of both 2000 and 1999.

         Consolidated capitalized software development costs, primarily in
the U.S., were $1.2 million and $3.5 million for the six months ended June
30, 2000 and 1999, respectively.

Impact of Inflation

         Inflation has slowed in recent years and is currently not an
important determinant of the Company's results of operations. To the extent
permitted by competitive conditions, the Company passes increased costs on
to customers by adjusting sales prices and, in the case of multi-year
contracts, through consumer price index provisions in such agreements.

RESTRUCTURING CHARGES

         In the third quarter of 1999, the Company initiated a
comprehensive program named Project Delta, with the objective to improve
productivity and operating efficiencies to reduce the Company's on-going
cost structure in its U.S. operations. The first phase of Project Delta
included the identification and assessment of potential operating
efficiencies in the Company's various U.S. functional areas and was
completed in the fourth quarter of 1999. The cost reduction program
implementation began in the first quarter of 2000, with cost savings of
approximately $6.0 million to $8.0 million achieved year to date. The
Company expects that annualized cost savings in certain expenses of at
least $15.0 million will be achievable in the U.S. operations by the end of
2000.

disbursed and 152 employees have been terminated under various Project
Delta initiatives. Additional provisions have been made throughout the year
to cover retention and relocation incentive costs that were not eligible
for accrual at December 31, 1999.

solidly progressing on its previously announced restructuring activities,
and that the restructuring provisions recorded will be adequate to cover
the estimated restructuring costs. The Company anticipates that it will
continue to incur restructuring charges in 2000 for items that do not meet
the criteria for accrual and for future restructurings. The Company expects
to incur additional costs of $8.0 million to $10.0 million relating to the
first phase of Project Delta which could not be accrued as of June 30,
2000. In addition, the Company has begun the initial stages of reviewing
its International and information technology operations to assess potential
restructuring costs and benefits. The Company cannot yet estimate the costs
for these future restructuring programs.

OTHER CHARGES

         In the fourth quarter of 1999, Restructuring and Other Charges
included a $.9 million charge for a non-current receivables reserve. This
reserve was reversed in the second quarter of 2000 pursuant to a settlement
agreement reached with the other party.

EUROPEAN CURRENCY CONVERSION ISSUES

         In accordance with the 1992 treaty of the European Union, on
January 1, 1999, a new single European currency, the Euro, became legal
tender. The Euro will replace the sovereign currencies ("legacy
currencies") of the eleven initial members of the European Union
("participating countries"). On this date, fixed conversion rates between
the Euro and the legacy currencies in those particular countries were
established.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
            OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS, CONT'D.



         As the Company has operations in several of the participating
countries, it will be affected by issues relating to the introduction of and
transition to the Euro. The Company's European Executive Committee is charged
with formulating and executing all aspects of the Company's plan concerning the
conversion to the Euro.

         The Company does not expect the cost of any system modifications
to be material or result in any material increase in transaction costs. The
Company will continue to evaluate the impact of the Euro, however, based on
currently available information, management does not believe the
introduction of the Euro will have a material adverse impact on the
Company's financial condition or overall trends in results of operations.

                                OTHER INFORMATION



ITEM 1.  LEGAL PROCEEDINGS

         On July 29, 1996, IRI filed an action against The Dun & Bradstreet
         Corp., The A.C. Nielsen Company (now a subsidiary of ACNielsen) and
         IMS International, Inc. (collectively, "the Defendants") in the United
         States District Court for the Southern District of New York entitled
         Information Resources, Inc. v. The Dun & Bradstreet Corp., et. al. No.
         96 CIV. 5716 (the "Action"). IRI alleged that, among other things, the
         Defendants violated Sections 1 and 2 of the Sherman Act, 15 U.S.C.
         Sections 1 and 2, by engaging in a series of anti-competitive
         practices aimed at excluding the Company from various export markets
         for retail tracking services and regaining monopoly power in the
         United States market for such services. By the Action, the Company
         seeks to enjoin the Defendants' anti-competitive practices and to
         recover damages in excess of $350.0 million, prior to trebling. The
         Action is more particularly described in the Company's Annual Report
         on Form 10-K for the fiscal year ended December 31, 1999. See "Legal
         Proceedings" contained therein. On July 13, 2000, the District Court
         in a procedural ruling held that IRI lacked standing to assert claims
         for injury suffered from Defendants' activities in foreign markets
         where IRI operates through subsidiaries or companies owned by joint
         ventures and dismissed such claims. The District Court left open the
         issue of whether those subsidiaries and joint ventures could sue in
         the United States for injury suffered from Defendants' activities in
         the foreign markets where they operate.
