             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

A.       BASIS OF PRESENTATION

         The consolidated balance sheet of Information Holdings Inc. (IHI , or
         the Company) at December 31, 1998 has been derived from IHI's Annual
         Report on Form 10-K for the year then ended. All other consolidated
         financial statements contained herein have been prepared by IHI and are
         unaudited. The financial statements should be read in conjunction with
         the financial statements for the year ended December 31, 1998 and the
         notes thereto contained in IHI's Annual Report on Form 10-K for the
         year then ended.

         The accompanying unaudited consolidated financial statements have been
         prepared in accordance with Article 10 of Regulation S-X for interim
         financial statements required to be filed with the Securities and
         Exchange Commission and do not include all information and footnotes
         required by generally accepted accounting principles for complete
         financial statements. However, in the opinion of management, the
         accompanying unaudited consolidated financial statements contain all
         adjustments, consisting only of normal recurring adjustments, necessary
         to present fairly the consolidated financial position of IHI as of
         September 30, 1999, and the consolidated results of its operations and
         its cash flows for the periods presented herein. Results for the three
         and nine months ended September 30, 1999 are not necessarily indicative
         of the results to be expected for the full fiscal year.

B.       INVENTORIES

         Inventories are stated at the lower of cost (first-in, first-out
         method) or market. Inventories at September 30, 1999 and December 31,
         1998 consist solely of finished goods. The vast majority of inventories
         are books, which are reviewed periodically on a title-by-title basis
         for salability. The cost of inventory determined to be impaired is
         charged to income in the period of determination.

C.       PRE-PUBLICATION COSTS

         Certain expenses related to books, primarily comprised of design and
         other pre-production costs, are deferred and charged to expense over
         the estimated product life. These costs are primarily amortized over a
         four-year period following release of the applicable book, using an
         accelerated amortization method. During 1999, the Company removed from
         its Balance Sheet fully amortized pre-publication costs of
         approximately $1,645,000.

D.       RECLASSIFICATIONS

         Certain amounts in the fiscal 1998 financial statements have been
         reclassified to conform to the 1999 financial statement presentation.

</TABLE>

         During the third quarter of 1999, employees exercised stock options to
         acquire 4,882 shares at an exercise price of $12 per share.

         No historical earnings per share data are presented for the three
         months and nine months ended September 30, 1998, as the Company does
         not consider such data meaningful. The pro forma earnings per share
         data presented were computed using 16,943,189 shares outstanding, which
         reflects all shares outstanding following the Company's initial public
         offering in August 1998, as if such shares were outstanding since
         January 1, 1998.


F.       IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         In June 1999, the Financial Accounting Standards Board (FASB) issued
         Statement No. 137, "Accounting for Derivative Instruments and Hedging
         Activities - Deferral of the Effective Date of FASB Statement No. 133.
         The Statement defers for one year the effective date of FASB Statement
         No. 133, "Accounting for Derivative Instruments and Hedging
         Activities," which establishes accounting and reporting standards for
         derivative instruments and for hedging activities. The rule will now
         apply to all fiscal quarters of all fiscal years beginning after June
         15, 2000. In the opinion of the Company's management, adoption of this
         new accounting standard will not have any impact on the Company's
         consolidated financial position or results of operations.

G.       ACQUISITIONS

         On September 1, 1999, the Company acquired the assets of the Corporate
         Intelligence (CI) business of Innovator Corporation for cash
         consideration of approximately $8,000,000. CI provides intellectual
         property information and related software and searching tools,
         primarily through the Internet. The purchase price was
         preliminarily allocated to publishing rights and other intangible
         assets of $7,900,000 and non-compete agreements of $100,000.

         On August 12, 1999, the Company acquired all of the outstanding capital
         stock of Master Data Center, Inc. (MDC), a Michigan corporation, for
         cash consideration of approximately $33,000,000. MDC provides patent
         annuity tax payment services for owners of intellectual property in
         domestic and foreign markets and complementary software products for
         managing patent and trademark portfolios. The purchase price was
         preliminarily allocated to net liabilities assumed of $7,150,000, and
         publishing rights and other intangible assets of $40,150,000. The
         Company also recorded goodwill and an offsetting deferred income tax
         liability as a result of the gross up of acquired intangible assets in
         the amount of $15,622,000. This goodwill is being amortized using the
         straight-line method over 20 years. Amortization expense for the nine
         months ended September 30, 1999 was $105,000.

         On July 19, 1999, the Company acquired all of the assets of Faxpat,
         Inc. (Faxpat) for cash consideration of approximately $9,300,000.
         Faxpat is a leading provider of patent documents and file histories to
         the legal and corporate markets. The purchase price was
         preliminarily allocated to net tangible assets of $500,000, publishing
         rights and other intangible assets of $8,700,000 and non-compete
         agreements of $100,000.

         The above acquisitions have all been accounted for using the purchase
         method of accounting and, accordingly, the results of their operations
         have been included in the Company's results of operations from their
         respective dates of acquisition.

         The pro forma unaudited results of operations for the nine months ended
         September 30, 1999 and September 30, 1998, assuming consummation of the
         MDC acquisition as of January 1, 1998 are as follows:

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) (Continued)

H.       REVOLVING CREDIT FACILITY

         On September 24, 1999, the Company entered into a seven-year revolving
         credit facility in an amount not to exceed $50,000,000 initially,
         including a $10,000,000 sublimit for the issuance of standby letters of
         credit (the Credit Facility). Total commitments under the Credit
         Facility shall be permanently reduced to $45,000,000 at the end of the
         third year, $37,500,000 at the end of the fourth year, $25,000,000 at
         the end of the fifth year and $12,500,000 at the end of the sixth year.
         The proceeds from the Credit Facility are intended to be used to fund
         acquisitions, to meet short-term working capital needs and for general
         corporate purposes.

         Borrowings under the Credit Facility bear interest at either the higher
         of the bank's prime rate and one-half of 1% in excess of the overnight
         federal funds rate plus a margin of 0.50% to 1.25% or the Eurodollar
         Rate plus a margin of 1.5% to 2.25% depending on the Company's ratio of
         indebtedness to earnings before interest, taxes, depreciation and
         amortization. The Company also pays a commitment fee of 0.375% on the
         unused portion of the Credit Facility. As of September 30, 1999, the
         Company had no outstanding borrowings under the Credit Facility.

         Under the terms of the Credit Facility, the Company is required to
         maintain certain financial ratios related to fixed charge coverage,
         leverage and interest coverage, in addition to certain other covenants.
         As of September 30, 1999, the Company was in compliance with all
         covenants. The Credit Facility is secured by a first priority perfected
         pledge of all notes and capital stock owned by the Company's
         subsidiaries and a first priority perfected security interest in all
         other assets of the Company and its subsidiaries, subject to certain
         exceptions. Obligations under the Credit Facility will be guaranteed by
         the Company and its subsidiaries. The Credit Facility also prohibits
         the Company from incurring certain additional indebtedness, limits
         certain investments, mergers or consolidations and restricts
         substantial asset sales, and dividends.

I.       SUBSEQUENT EVENT

         LEGAL PROCEEDINGS

         As previously disclosed, Mason P. Slaine, the Company's President and
         Chief Executive Officer, and Michael E. Danziger, a director of the
         Company, are shareholders, officers and directors of Rand Publishing
         Company Inc. (Rand), a private holding company that has made
         investments in the publishing industry, and are defendants in a lawsuit
         alleging that Mr. Slaine breached his fiduciary duty to certain other
         investors and usurped corporate opportunities available to Rand by
         investing in the Company and by participating in the acquisition by the
         Company of various businesses.

         On December 2, 1998, Rand and Mr. Slaine filed a motion to dismiss the
         Rand investors' complaint against them. The court granted the motion on
         November 3, 1999 on the grounds that the plaintiffs had not alleged
         with particularity the efforts, if any, they had made to impel the
         board of directors of Rand to initiate these derivative claims in the
         first instance. The motion was granted with leave to plaintiffs to
         serve an amended complaint setting forth in detail the reasons why such
         demand on the Rand board would have been futile.

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

RESULTS OF OPERATIONS:

Three Months Ended September 30, 1999 Compared to
Three Months Ended September 30, 1998
-------------------------------------------------

         REVENUES. In the third quarter of 1999, the Company had revenues of
$14.8 million compared to revenues of $11.5 million in the third quarter of
1998, an increase of $3.3 million or 28.9%. The increase in revenues is
primarily due to revenues of $1.3 at Master Data Center, which was acquired in
August 1999; an increase of $1.1 million in sales of patents and file histories
at Optipat and Faxpat, businesses acquired in 1999; an increase of $0.9 in
Internet sales at MicroPatent; and an increase of $0.5 million in book sales at
CRC Press. These increases were partly offset by a decline of $0.6 million at
CRC's Auerbach unit, due in part to a transition to a web-based product line.

         COST OF SALES. Cost of sales increased $1.1 million or 39.8% to $3.8
million in the third quarter of 1999 compared to $2.7 million in the
corresponding quarter in 1998. Cost of sales expressed as a percentage of
revenues in the third quarter of 1999 increased to 25.9% from 23.9% for the
corresponding quarter of 1998. The increase in the costs of sales percentage
over the comparable period in 1998 is primarily attributable to the acquisition
of MDC which has lower gross margins than the other IHI units; and the
acquisitions of Optipat and Faxpat which have higher cost structures than
MicroPatent. These increases were partially offset by slightly lower costs at
CRC Press primarily related to book publishing operations.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (SG&A). SG&A expenses
increased $1.3 million or 22.6% in the third quarter of 1999, to $7.2 million
from $5.9 million in the third quarter of 1998, principally as a result of
operating expenses of businesses acquired in 1999 and increased personnel costs
at CRC Press, due to business growth. SG&A expenses as a percentage of revenues
decreased to 48.6% in the third quarter of 1999, compared to 51.1% in the
corresponding 1998 quarter.

         DEPRECIATION AND AMORTIZATION. Depreciation and amortization in the
third quarter of 1999 increased $0.3 million, or 24.1%, to $1.7 million from
$1.4 million in the corresponding quarter in 1998, due primarily to increased
amortization of intangible assets as a result of acquisitions during fiscal
1999.

         SEVERANCE AND SPECIAL BONUSES. Included in the third quarter of 1998 is
a charge of $1.0 million related to severance and special bonuses at a
subsidiary.

         INTEREST INCOME. Interest income decreased to $0.3 million from $0.5
million due primarily to the use of the proceeds from the initial public
offering for acquisitions during the third quarter of 1999.

         INCOME TAXES. The provision for income taxes as a percentage of pre-tax
income for the three months ended September 30, 1999 is 44.5%, which differs
from the statutory rate primarily as a result of non-deductible amortization in
excess of the purchase price over net assets acquired. This compares with an
effective tax rate of 5.0% in the prior year. The Company did not record a
provision for Federal income taxes in the prior year period due to the use of
net operating loss carry-forwards.

            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

Nine Months Ended September 30, 1999 Compared to
Nine Months Ended September 30, 1998
------------------------------------------------

         REVENUES. In the first nine months of 1999, the Company had revenues of
$39.9 million compared to revenues of $32.6 million in the first nine months of
1998, an increase of $7.3 million or 22.3%. The increase in revenues is
primarily due to an increase of $2.0 million in book sales at CRC Press; an
increase of $1.9 million in Internet sales at MicroPatent; an increase of $1.5
million in CRC Press electronic product sales; an increase of $2.1 million in
sales of patents and file histories at Optipat and Faxpat; and revenues of $1.3
million at MDC. These increases were partly offset by a decline of $1.2 million
at CRC's Auerbach unit, due in part to a transition to a web-based product line.

         COST OF SALES. Cost of sales increased $2.5 million or 30.3% to $10.6
million in the first nine months of 1999 compared to $8.1 million in the
corresponding period in 1998. Cost of sales expressed as a percentage of
revenues in the first nine months of 1999 increased to 26.6% from 24.9% for the
corresponding period of 1998. The increase in the costs of sales percentage over
the comparable period in 1998 is primarily attributable to the inclusion of
recently acquired businesses, which have lower gross margins than the existing
businesses.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (SG&A). SG&A expenses
increased $2.7 million or 14.8% in the first nine months of 1999, to $20.9
million from $18.2 million for the first nine months of 1998, principally as a
result of operating expenses of businesses acquired in 1999 and increased
personnel costs at CRC Press, due to business growth. SG&A expenses as a
percentage of revenues decreased to 52.4% in the first nine months of 1999,
compared with 55.9% in the corresponding 1998 period.

         DEPRECIATION AND AMORTIZATION. Depreciation and amortization for the
first nine months of 1999 decreased $0.2 million, or 4.7%, to $3.7 million from
$3.9 million in the corresponding period in 1998, due primarily to decreased
amortization of intangible assets.

         SEVERANCE AND SPECIAL BONUSES. Included in the first nine months of
1998 is a charge of $1.0 million related to severance and special bonuses at a
subsidiary.

         INTEREST INCOME. Interest income increased to $1.5 million from $0.7
million due primarily to interest earned on the proceeds from the initial public
offering.

         INCOME TAXES. The provision for income taxes as a percentage of pre-tax
income for the nine months ended September 30, 1999 is 41.1%, which differs from
the statutory rate primarily as a result of non-deductible amortization in
excess of the purchase price over net assets acquired. This compares with an
effective tax rate of 7.7% in the prior year. The Company did not record a
provision for Federal income taxes in the prior year period due to the use of
net operating loss carry-forwards.

                            INFORMATION HOLDINGS INC.

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


FINANCIAL CONDITION:

Prior to August 1998, the financing requirements of the Company have been funded
through cash generated by operating activities and capital contributions from
the founding stockholders. In August 1998, the Company completed an initial
public offering of its common stock to raise funds. On September 24, 1999, the
Company entered into a seven-year revolving credit facility in an amount not to
exceed $50,000,000 initially, including a $10,000,000 sublimit for the issuance
of standby letters of credit (the Credit Facility). Total commitments under the
Credit Facility shall be permanently reduced to $45,000,000 at the end of the
third year, $37,500,000 at the end of the fourth year, $25,000,000 at the end of
the fifth year and $12,500,000 at the end of the sixth year. The proceeds from
the Credit Facility are intended to be used to fund acquisitions, to meet
short-term working capital needs and for general corporate purposes.

Borrowings under the Credit Facility bear interest at either the higher of the
bank's prime rate and one-half of 1% in excess of the overnight federal funds
rate plus a margin of 0.50% to 1.25% or the Eurodollar Rate plus a margin of
1.5% to 2.25% depending on the Company's ratio of indebtedness to earnings
before interest, taxes, depreciation and amortization. The Company also pays a
commitment fee of 0.375% on the unused portion of the Credit Facility. As of
September 30, 1999, the Company had no outstanding borrowings under the Credit
Facility.

Under the terms of the Credit Facility, the Company is required to maintain
certain financial ratios related to fixed charge coverage, leverage and interest
coverage, in addition to certain other covenants. As of September 30, 1999, the
Company was in compliance with all covenants. The Credit Facility is secured by
a first priority perfected pledge of all notes and capital stock owned by the
Company's subsidiaries and a first priority perfected security interest in all
other assets of the Company and its subsidiaries, subject to certain exceptions.
Obligations under the Credit Facility will be guaranteed by the Company and its
subsidiaries. The Credit Facility also prohibits the Company from incurring
certain additional indebtedness, limits certain investments, mergers or
consolidations and restricts substantial asset sales, and dividends.

Cash and cash equivalents totaled $2.9 million at September 30, 1999 compared to
$57.3 million at December 31, 1998. Excluding cash and cash equivalents, the
Company had working capital of $(0.7) million at September 30, 1999 compared to
working capital of $0.2 million at December 31, 1998. Since the Company receives
patent annuity tax payments and subscription payments in advance, the Company's
existing operations are expected to maintain very low or negative working
capital balances, excluding cash. Included in current liabilities at September
30, 1999 are obligations related to annuity payments and deferred revenue of
approximately $19.7 million.

                            INFORMATION HOLDINGS INC.

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

FINANCIAL CONDITION (CONTINUED):

Cash generated from operating activities was $2.3 million for the nine months
ended September 30, 1999, derived from net income of $3.5 million plus non-cash
charges of $5.5 million less an increase in operating assets, net of liabilities
of $6.7 million. The increase in net operating assets is primarily the result of
increased customer receivables as a result of the businesses acquired in fiscal
1999, offset by payment of royalties and other expenses related to book
publishing operations.

Cash used in investing activities was $55.7 million for the nine months ended
September 30, 1999 due to acquisition costs of $53.4 million and capital
expenditures, including pre-publication costs, of $2.3 million. Excluding
acquisitions of businesses and titles, the Company's existing operations are not
capital intensive.

Cash used in financing activities was $1.0 million for the nine months ended
September 30, 1999, primarily related to payments of $0.2 million on
approximately $2.8 million of capitalized lease obligations and $0.9 of fees
associated with the new Credit Facility. The Company has no outstanding debt
obligations at September 30, 1999 related to the new Credit Facility.

The Company believes that funds generated by operations, together with cash on
hand and borrowings available under its current credit facility will be
sufficient to fund the cash requirements of its existing operations for the
foreseeable future. The Company currently has no commitments for material
capital expenditures or agreements with respect to any prospective material
acquisitions. The Company may require or choose to obtain additional capital or
financing to consummate future acquisitions.

SEASONALITY

The Company's business is somewhat seasonal, with revenues typically reaching
slightly higher levels during the third and fourth quarters of each calendar
year, based on historical publication schedules. In 1998, 30% of the Company's
revenues were generated during the fourth quarter with the first, second and
third quarters accounting for 23%, 22% and 25% of revenues, respectively. In
addition, the Company may experience fluctuation in revenues from period to
period based on the timing of acquisitions and new product launches.

YEAR 2000 COMPLIANCE

The Year 2000 issue is the result of computer systems that use two digits rather
than four to define the applicable year, which may prevent such systems from
accurately processing dates ending in the Year 2000 and after. This could result
in system failures or in miscalculations causing disruption of operations,
including, but not limited to, an inability to process transactions, to send and
receive electronic data, or to engage in routine business activities and
operations.

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

YEAR 2000 COMPLIANCE (CONTINUED):

The Company has completed its assessment of all currently used computer systems
and is in the final stages of completing a plan of action to correct those areas
that will be affected by the Year 2000 issue. Conversion of all critical data
processing systems is virtually complete. The Company anticipates that the
conversion of the remaining critical systems and all non-critical systems will
be completed by the end of November 1999. Presently, the Company has completed
the conversion of all environmental equipment, telephones, personal computer
hardware and software outside of the Company's information systems.

The Company expects the cost for all upgrades to be approximately $110,000; the
cost incurred to date is $70,000. The estimate includes internal costs, but
excludes the costs to upgrade and replace systems in the normal course of
business. The Company's goal is to complete any upgrade requirements by the end
of fiscal 1999, but does not expect that the cost for subsequent upgrades will
be material to the Company's consolidated financial statements.

Management's assessment of the risks associated with the Year 2000 project and
the status of the Company's contingency plans are unchanged from that described
in the 1998 Annual Report on Form 10-K.

ITEM 1.  LEGAL PROCEEDINGS

         As previously disclosed, Mason P. Slaine, the Company's President and
         Chief Executive Officer, and Michael E. Danziger, a director of the
         Company, are shareholders, officers and directors of Rand Publishing
         Company Inc. (Rand), a private holding company that has made
         investments in the publishing industry, and are defendants in a lawsuit
         alleging that Mr. Slaine breached his fiduciary duty to certain other
         investors and usurped corporate opportunities available to Rand by
         investing in the Company and by participating in the acquisition by the
         Company of various businesses.

         On December 2, 1998, Rand and Mr. Slaine filed a motion to dismiss the
         Rand investors' complaint against them. The court granted the motion on
         November 3, 1999 on the grounds that the plaintiffs had not alleged
         with particularity the efforts, if any, they had made to impel the
         board of directors of Rand to initiate these derivative claims in the
