                                  THE COMPANY
 
OVERVIEW
 
   
    The Company is an information publishing business focused on providing
essential information to professional and academic end-users in attractive niche
markets. The Company was formed to capitalize on management's experience in
acquiring information publishing businesses and then increasing profitability
through a combination of organic revenue growth and improved operating
efficiencies. To date, the Company has acquired information publishing
businesses in the following niche markets: scientific, technical and medical
("STM") and professional through CRC Press; and intellectual property through
MicroPatent. For the year ended December 31, 1997, the Company had revenues, net
loss and EBITDA of $34.9 million, ($4.9) million and $1.4 million, respectively.
These figures reflect the Adjustments (as defined on page 10), which reduced
revenues by $4.0 million and net income and EBITDA by $8.0 million.
    
 
    CRC Press, acquired in January 1997 from The Times Mirror Company, is a
mid-sized STM and professional publisher with leading positions in several
attractive niche markets. CRC Press, with a 95-year history, has highly regarded
brand names and publishes some of the most recognizable STM titles in their
respective fields, including THE HANDBOOK OF CHEMISTRY AND PHYSICS (currently in
its 79th edition) and STANDARD MATHEMATICAL TABLES AND FORMULAE. In the first
half of 1997, two fold-in acquisitions were completed and combined with CRC
Press: St. Lucie Press, a publisher of professional titles; and Auerbach, a
provider of technology-oriented print and electronic subscription-based
products, which was acquired from The Thomson Corporation ("Thomson"). For the
three months ended March 31, 1998, CRC Press contributed approximately 83% of
the Company's revenues.
 
    MicroPatent, acquired in July 1997, is a leading source of intellectual
property information products and services. Its high-quality patent and
trademark databases are used extensively by legal and research professionals and
corporations. The Internet, MicroPatent's fastest-growing distribution channel,
accounted for 34% of its total revenues in the first quarter of 1998, as
compared to 14% in the first quarter of 1997. The Company believes that its
profitable PATENTWEB-TM- service is among the most comprehensive intellectual
property information services on the Internet. For the three months ended March
31, 1998, MicroPatent contributed approximately 17% of the Company's revenues.
 
MANAGEMENT
 
   
    The Company was formed in December 1996 by Mason P. Slaine and Warburg,
Pincus Ventures, L.P. ("Warburg Pincus"). Mr. Slaine, the Company's President
and Chief Executive Officer, has more than 15 years of experience in the
information publishing industry in both corporate and entrepreneurial
environments. From 1994 to 1996, he served as President of Thomson Financial
Services ("Thomson Financial"), a unit of Thomson which is a leading provider of
financial information, research, analysis and software products worldwide.
    
 
    Vincent A. Chippari, the Company's Executive Vice President and Chief
Financial Officer, has extensive experience in information publishing, business
management, consulting and finance, including
 
                                       5
<PAGE>
seven years in various senior level operating and financial capacities with
Thomson. Messrs. Slaine and Chippari are complemented by strong operating
management. Dennis Buda, President of CRC Press, and Steven Wolfson, President
of MicroPatent, each have more than 20 years of experience in the information
publishing industry. See "Management--Executive Officers and Directors." Upon
consummation of the Offering, the executive officers of the Company will own an
aggregate of approximately 15.4% of the outstanding Common Stock, assuming an
initial public offering price of $15.50 per share. See "Security Ownership of
Certain Beneficial Owners and Management."
 
GROWTH AND OPERATING STRATEGY
 
    The principal elements of the Company's growth strategy are to (i) acquire
businesses in attractive niche markets, (ii) organically grow revenues and
profit, (iii) improve operating efficiencies and (iv) attract and retain
superior management.
 
    ACQUIRE BUSINESSES IN ATTRACTIVE NICHE MARKETS.  The Company actively seeks
to identify and acquire information publishing businesses with attractive
market, product and customer characteristics. The Company targets professional
and academic end-users who have a critical need to keep abreast of current
developments in their particular fields. While the Company continually develops
and introduces new products, the majority of the Company's revenues are
generated from recurring sources, such as subscriptions and sales of previously
released publications ("backlist"). The Company believes that markets in which
information is critical to success, such as the STM market served by the
Company, have supported consistent price increases over the past decade.
Examples of additional niche markets that the Company may target include
business information, healthcare information, regulatory information and
technology-related information. Upon the expiration of Mr. Slaine's non-compete
agreement with Thomson at the end of 1999, the Company may also pursue
opportunities in financial information publishing. See "Management--Slaine
Non-competition Agreement."
 
    ORGANICALLY GROW REVENUES AND PROFIT.  The Company seeks to acquire
information publishing businesses with significant short- and long-term growth
prospects. The Company's strategy is to acquire valuable content and leverage
such content across new distribution platforms and through expansion of product
lines. For example, the Company has launched new electronic versions of
successful print products, increased sales of core products based on new
distribution agreements, began Internet delivery of products and launched new
products targeting segments of its existing customer base.
 
    IMPROVE OPERATING EFFICIENCIES.  The Company seeks to improve operating
efficiencies by combining administrative functions, eliminating redundant
facilities, negotiating more favorable contract terms with suppliers,
implementing systems improvements and upgrading management. In addition, the
Company seeks to leverage its infrastructure by acquiring companies or product
lines which can be supported by its existing operations. To date, CRC Press has
acquired two such companies, St. Lucie Press and Auerbach, as well as a line of
engineering titles from Krause Communications and the McGee line of business
titles.
 
    ATTRACT AND RETAIN SUPERIOR MANAGEMENT.  The Company seeks to employ
professional management with substantial information publishing expertise, both
in entrepreneurial and corporate settings. The Company's philosophy is to
provide its operating units with significant decision-making authority, so that
key operating policies are made close to the Company's customers and operations.
This enables the Company to attract superior entrepreneurial talent who can grow
the business by capitalizing on market opportunities.
 
                                   BACKGROUND

                SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA
 
    The summary historical financial data of the Company as of and for the year
ended December 31, 1997 and as of and for the three months ended March 31, 1998
were derived from its audited financial statements. The summary historical
financial data as of and for the three months ended March 31, 1997 has been
derived from unaudited financial statements, which in the opinion of management
include all adjustments, consisting only of normal recurring adjustments,
necessary for a fair presentation of the results for such period. The summary
unaudited pro forma financial data for the year ended December 31, 1997 includes
adjustments to reflect the results of operations as if each acquisition was
consummated as of January 1, 1997 and certain other adjustments as more fully
described on the financial pages of this Prospectus. The unaudited pro forma
data is not designed to represent and does not represent what the Company's
results of operations actually would have been had the transactions described
herein under "Unaudited Pro Forma Condensed Consolidated Statement of
Operations" been completed as of January 1, 1997 or to project the Company's
results of operations at any future date or for any future period. The Company
acquired Auerbach on June 5, 1997 and MicroPatent on July 2, 1997 in
transactions accounted for under the purchase method of accounting. The results
of operations of these businesses were included in the Company's results from
their respective dates of acquisition. Accordingly, the operating results for
the three months ended March 31, 1997 and the three months ended March 31, 1998
are not fully comparable. The summary historical financial data should be read
in conjunction with, and are qualified by reference to, "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and the financial
statements and notes thereto included elsewhere in this Prospectus.

- ------------------------
   
(1) In conjunction with the acquisition and reorganization of CRC Press and
    other businesses and certain compensation issues, the Company recorded
    significant adjustments in 1997 and early 1998, which are not expected to
    continue in the future. These adjustments (the "Adjustments") reduced
    revenues by $4,017 and increased expenses by $4,013, and therefore reduced
    net income by $8,030, for the year ended December 31, 1997. The Adjustments
    reduced revenues by $693 and $54 and increased expenses by $1,968 and $146,
    and therefore reduced net income by $2,661 and $200, for the three-month
    periods ended March 31, 1997 and March 31, 1998, respectively. The
    Adjustments affecting revenues were required by purchase accounting in
    connection with the acquisitions of CRC Press and MicroPatent and reflect
    the revaluation of acquired deferred subscription revenues based on the cost
    to fulfill subscriptions. This revaluation is a non-cash adjustment which
    reduces revenues in the twelve months following acquisition. The Adjustments
    affecting expenses relate to: severance and reorganization costs from the
    consolidation of certain functions and reductions in workforce; special
    bonuses granted to an officer; contingent compensation paid to an officer of
    a subsidiary; and certain additional purchase accounting-related
    adjustments. Historical operating loss and EBITDA of ($4,663) and $1,444,
    respectively, for the year ended December 31, 1997 include the effect of the
    Adjustments of $8,030.
    
 
(2) Revenues for the three months ended March 31, 1997 and the year ended
    December 31, 1997 include an initial stocking order by a new international
    distributor aggregating $3,307, which is not expected to continue in the
    future.
 
(3) Historical income taxes of the Company are not significant. Prior to the
    Exchange, the Company was a limited liability company and, accordingly, was
    not subject to U.S. federal or certain state income taxes.
 
(4) The Company's results of operations for the fiscal quarter in which the
    Offering is consummated will be adversely affected by the payment of
    approximately $1.0 million in cash and shares of Common Stock as incentive
    payments to Dennis Buda. See "Management--Employment Agreements."
 
(5) No historical earnings per share data are presented as the Company does not
    consider such historical data meaningful. Pro forma basic earnings (loss)
    per share were computed by using 16,466,129 shares of Common Stock
    outstanding after giving effect to the Exchange, the Offering and shares
    issuable under an employment agreement, as if such shares were outstanding
    on January 1, 1997, assuming an initial public offering price of $15.50 per
    share.
 
(6) As adjusted amounts give effect to the issuance and sale of 4,250,000 shares
    of Common Stock in the Offering (assuming an initial public offering price
    of $15.50 per share), after deducting underwriting discounts and estimated
    offering expenses.
 
(7) Depreciation and amortization include balances related to property and
    equipment, intangible assets and pre-publication costs incurred in book
    publishing operations. Capital expenditures include property and equipment
    and pre-publication costs.
 
(8) For details of operating, investing and financing activities, see the
    Company's Consolidated Statements of Cash Flow for the year ended December
    31, 1997 and for the three months ended March 31, 1998, included elsewhere
    in this Prospectus.
 
(9) "EBITDA" is defined as income before interest expense/income, income taxes,
    depreciation and amortization. EBITDA is not a measure of performance under
    generally accepted accounting principles ("GAAP") and should not be
    considered in isolation or as a substitute for net income, cash flow from
    operations or other income or cash flow data prepared in accordance with
    GAAP. Items excluded from the calculation of EBITDA are significant
    components in understanding and evaluating the Company's financial
    performance. While EBITDA should not be considered as a measure of
    profitability or liquidity, the Company understands that EBITDA is
    customarily used in evaluating the equity value of publishing companies. The
    EBITDA measure presented herein may not be comparable to similarly titled
    measures of other companies.

<PAGE>
                                  RISK FACTORS
 
    PROSPECTIVE INVESTORS SHOULD TAKE INTO ACCOUNT THE CONSIDERATIONS SET FORTH
BELOW AS WELL AS THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS BEFORE
PURCHASING ANY OF THE SHARES OF COMMON STOCK OFFERED HEREBY.
 
LIMITED OPERATING HISTORY; OPERATING LOSSES
 
   
    The Company has completed numerous acquisitions since it commenced
operations in January 1997. Consequently, the financial results of the Company
and its subsidiaries included in this Prospectus are not necessarily indicative
of their future financial condition or results of operations. As a result of
adjustments in the aggregate amount of $8.0 million recorded in conjunction with
the acquisition and reorganization of businesses and certain compensation
issues, the Company reported a pre-tax loss of $(4.9) million for the year ended
December 31, 1997. The predecessor to the Company also reported pre-tax losses
in 1993, 1995 and 1996 of ($3.9) million, ($14.1) million and ($11.1) million,
respectively. See "Selected Historical Financial Data." Although the Company
achieved profitability for the three months ended March 31, 1998, there can be
no assurance that the Company will sustain profitability in the future, In
addition, the Company's results of operations for the fiscal quarter in which
the Offering is consummated will be adversely affected by the payment of
approximately $1.0 million in cash and shares of Common Stock as incentive
payments to Dennis Buda. See "Management--Employment Agreements."
    
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company believes that its success depends principally upon the efforts
and abilities of Mason P. Slaine, its co-founder, President and Chief Executive
Officer. In addition, the Company believes that its success will depend to a
significant extent upon the efforts and abilities of Vincent A. Chippari, its
Executive Vice President and Chief Financial Officer. Neither individual has
served as chief executive officer or chief financial officer, respectively, of a
public company. The successful operations of the Company's subsidiaries will
also depend on the senior management teams of such subsidiaries who are
currently in the employ of the Company and those the Company will hire in
connection with future acquisitions. The inability to hire and retain qualified
employees in connection with future acquisitions or to replace the loss of the
services of one or more key employees could have a material adverse effect on
the Company's financial condition and results of operations. The Company does
not currently maintain key person life insurance with respect to any of its
employees.
 
RISKS ASSOCIATED WITH ACQUISITIONS
 
    The Company's growth will depend in part on its ability to consummate
acquisitions, integrate such acquisitions into existing operations, manage
expansion, achieve operating efficiencies and control costs in its operations.
This strategy will entail reviewing and potentially reorganizing the
infrastructure, management and financial controls of acquired operations. The
Company's financial condition and results of operations could be adversely
affected by unforeseen expenses, difficulties, complications and delays
frequently encountered in connection with the acquisition and integration of new
businesses. Acquisition-related costs could include severance payments to
employees of acquired companies, restructuring charges, assumption of
liabilities and amortization of goodwill and other acquired intangible assets,
as well as non-recurring acquisition costs, including accounting, legal and
other advisory fees. In addition, acquisitions may place a strain upon the
management resources and systems of the Company, requiring that the Company hire
additional personnel, implement new systems or upgrade existing systems.
 
    There can be no assurance that the Company will identify acquisition
candidates that result in successful business combinations or that acquisitions
will be consummated on acceptable terms. The Company competes for acquisition
targets with other companies, many of which are larger than the Company and have
greater financial resources. In addition, the Company seeks to acquire
businesses at what it considers to be attractive valuations, a policy which has
caused, and may in the future cause, the
 
                                       11
<PAGE>
Company to be outbid for otherwise desirable businesses. In general, the
magnitude, timing and nature of future acquisitions will depend upon various
factors, including the availability of suitable acquisition candidates, the
negotiation of acceptable terms, the Company's financial capabilities at the
time of the acquisition bid, the availability of skilled employees to manage the
acquired businesses and general economic and business conditions. There can be
no assurance that the Company will continue to be successful in completing
attractive acquisitions, integrating acquired businesses and improving their
profitability.
 
    The Company anticipates that it will finance future acquisitions through
cash on hand, borrowings and issuances of capital stock. The Company does not
currently have any commitments with respect to any acquisition financing, and
there can be no assurance that sufficient financing will be available, or, if
available, that it will be available on acceptable terms. In addition,
stockholders of the Company may experience dilution in the event that equity
securities are issued in connection with acquisitions. If adequate funds are not
available, the Company may be required to significantly curtail its acquisition
program.
 
COMPETITION
 
    The Company faces significant competition with respect to its STM and
professional and intellectual property businesses. In addition to competing for
sales on the basis of editorial quality of its publications, the Company
competes for the signing of noted authors. Many of the Company's competitors are
substantially larger than the Company and have greater financial, technical,
editorial, personnel and marketing resources, longer operating histories and
greater name recognition than the Company's. If the Company is unable to compete
effectively under these conditions, its financial condition and results of
operations will be materially adversely affected. See "Business--Competition."
 
RISKS RELATED TO AVAILABILITY OF SOURCE DATA
 
    Much of the source data for MicroPatent's information services is publicly
available in raw form at little or no cost. To the extent users of patent and
trademark data choose to extract the data they need from such public sources
rather than utilize MicroPatent's services, MicroPatent's financial condition
and results of operations could be adversely affected. See
"Business--Competition."
 
RISKS RELATED TO CHANGES IN TECHNOLOGY
 
    To the extent that the Company's businesses utilize the Internet and other
electronic media, they are subject to rapid changes in technology. There can be
no assurance that the development of new or improved technologies and products
by competitors will not have a material adverse effect on the Company's
electronically-based businesses, nor can there be any assurance that the Company
can remain competitive once such technologies and products are introduced.
 
RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION
 
    Approximately 24% of the Company's 1997 pro forma revenues, excluding the
Adjustments, were generated from sales outside North America (including an
initial stocking order by a new international distributor approximating 8% of
1997 pro forma revenues). The Company may increase its presence internationally
through internal growth and, possibly, through acquisitions. There are certain
risks inherent in doing business in international markets, such as the
uncertainty of product acceptance by different cultures, the risks of divergent
business expectations or difficulties in establishing joint ventures with
foreign partners, difficulties in staffing and managing multinational
operations, currency and interest rate fluctuations, reduced protection of
intellectual property rights, political instability, restrictions or limitations
on the repatriation of funds and potentially adverse tax consequences. There can
be no assurance that one or more of such factors will not have a material
adverse effect on the Company's future
 
                                       12
<PAGE>
international operations and, consequently, on the Company's financial condition
and results of operations.
 
RISKS RELATED TO THE YEAR 2000
 
    The year 2000 issue is the result of computer programs using two digits
rather than four to define the applicable year. As a result, those computer
programs have time-sensitive software that recognizes a date using "00" as the
year 1900 rather than the year 2000. This error could cause a system failure or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities. Although the Company expects that its
information technology will be ready for the year 2000, the Company cannot
effectively ensure against all potential year 2000 problems that might originate
with third parties. If the Company or any third party with whom the Company does
business were to have a year 2000 problem, the Company's business, especially
that of MicroPatent, could be seriously disrupted and the Company's financial
condition and results of operations could be materially adversely affected.
 
FLUCTUATIONS IN PAPER COSTS
 
    While the Company does not make significant direct paper purchases, paper
costs constitute a significant component of its printing expenses, which
expenses accounted for 8% of the Company's total operating expenses in 1997.
Paper prices have been volatile over the past several years, and management
anticipates such volatility to continue in the future. Significant increases in
paper prices could adversely affect the Company's financial condition and
results of operations.
 
RISKS RELATED TO USE OF PROCEEDS
 
    Substantially all of the net proceeds from the Offering will remain
uncommitted pending the intended application of such funds for general corporate
purposes, including acquisitions. Accordingly, management will have substantial
discretion in using the proceeds received by the Company until such time as
acquisitions are completed. In the interim, management intends to invest these
proceeds in short-term, investment grade securities, which will yield only that
rate of return earned by such securities and will be subject to the risks
inherent in investment in such securities. A delay in using such proceeds for
acquisitions may adversely affect the market price of the Common Stock.
 
    The principal purposes of the Offering are to (i) fund the Company's growth
through acquisition, (ii) create a public market for the Common Stock, which
will enable the Company to issue equity securities as consideration for
acquisitions and incentive compensation to employees, and (iii) facilitate
future access by the Company of public capital markets.
 
CONTROL BY PRINCIPAL STOCKHOLDERS; ANTI-TAKEOVER PROVISIONS
 
    Upon consummation of the Offering, the Initial Stockholders will own an
aggregate of 73.9% of the outstanding Common Stock. As a result, the Initial
Stockholders will have the ability to control the Company, including the
election of directors, and direct its affairs and business. Such concentration
of ownership, as well as certain provisions of the Company's Certificate of
Incorporation and the Delaware General Corporation Law (the "DGCL"), could have
the effect of delaying or preventing a change in control of the Company under
circumstances that could give holders of the Common Stock the opportunity to
realize a premium over the then prevailing market price of such stock. Such
provisions may also adversely affect the market price of the Common Stock. Such
provisions include the ability of the Board of Directors to issue preferred
stock without further action by stockholders (known as "blank check preferred
stock") and Section 203 of the DGCL, which, in general, imposes restrictions
upon certain acquirers of 15% or more of the Company's Common Stock. These
provisions could delay or frustrate the assumption of control by stockholders,
even if such assumption of control would be beneficial to stockholders, and also
 
                                       13
<PAGE>
could discourage or make more difficult a merger, tender offer or proxy contest,
even if such events could be beneficial to the interests of stockholders. See
"Description of Capital Stock."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon consummation of the Offering, the Company will have outstanding
16,466,129 shares of Common Stock. All of the 4,250,000 shares of Common Stock
to be sold in the Offering will be eligible for immediate sale in the public
market without restriction unless purchased by affiliates of the Company. All of
the remaining 12,216,129 outstanding shares of Common Stock (the "Restricted
Shares") are held by affiliates of the Company and are available for public
resale pursuant to Rule 144 under the Securities Act. All the Restricted Shares
are subject to the lock-up agreements described under "Underwriting." Further,
409,617 shares of Common Stock (assuming an initial public offering price of
$15.50 per share) are issuable at the initial public offering price per share
upon the exercise of stock options to be granted upon consummation of the
Offering. See "Management--1998 Stock Option Plan" and "Shares Eligible for
Future Sale." Sales of substantial amounts of Common Stock, or the perception
that such sales could occur, could adversely affect the market price of the
Common Stock. The Company may also determine to issue Common Stock to fund
acquisitions, which may have such an effect, as well as be financially dilutive
to stockholders.
    
 
NO PRIOR MARKET FOR THE COMMON STOCK
 
    Prior to the Offering, there has been no public market for the Common Stock.
There can be no assurance that an active public market for the Common Stock will
develop or be sustained after the Offering. The initial public offering price of
the Common Stock will be determined by negotiation between the Company and the
representatives of the Underwriters based on the factors described under
"Underwriting." There can be no assurance that the price at which the Common
Stock will trade in the public market after the Offering will not fall below the
initial public offering price. See "Underwriting."
 
DILUTION TO NEW INVESTORS
 
    Purchasers of Common Stock in the Offering will experience immediate and
substantial dilution in the amount of $11.35 per share in net tangible book
value per share. See "Dilution."
 
DIVIDENDS
 
    The Company has never declared or paid dividends on its Common Stock and
does not currently anticipate paying dividends in the future. There can be no
assurance that the Company will ever pay a dividend. See "Dividend Policy."

                                USE OF PROCEEDS
 
    The net proceeds to the Company from the Offering are estimated to be
approximately $59.9 million (approximately $69.1 million if the Underwriters'
over-allotment option is exercised in full) after deducting underwriting
discounts and estimated offering expenses (and assuming an initial offering
price of $15.50 per share). Such net proceeds will be used for general corporate
purposes, including acquisitions. The Company does not have any agreements,
arrangements or understandings with respect to any prospective material
acquisitions. Pending such uses, the net proceeds will be invested in
short-term, investment grade securities.
 
   
    The Company is in discussions to acquire two STM product lines located in
the United Kingdom. The proposed purchase price is approximately $4.0 million,
which will be paid with a portion of the proceeds of the Offering. No definitive
agreements have been signed, and there can be no assurance that such transaction
will be consummated.
    
 
    The principal purposes of the Offering are to (i) fund the Company's growth
through acquisition, (ii) create a public market for the Common Stock, which
will enable the Company to issue equity securities as consideration for
acquisitions and incentive compensation to employees, and (iii) facilitate
future access by the Company of public capital markets.
 
                                DIVIDEND POLICY
 
    The Company has never declared or paid dividends on the Common Stock. The
Company intends to retain future earnings, if any, to finance the development
and expansion of its business and, therefore, does not anticipate paying any
cash dividends on its Common Stock in the foreseeable future. The decision
whether to pay dividends will be made by the Board of Directors of the Company
in light of conditions then existing, including the Company's results of
operations, financial condition and requirements, business conditions and other
factors.

                                    DILUTION
 
    As of March 31, 1998, the pro forma net tangible book value of the Common
Stock, after giving effect to the Exchange, was approximately $8.5 million, or
approximately $0.69 per share. Net tangible book value per share represents the
amount of total tangible assets less total liabilities, divided by the number of
shares of Common Stock outstanding. After giving effect to the Offering
(assuming an initial public offering price of $15.50 per share and after
deducting estimated offering expenses), the pro forma net tangible book value of
the Company at March 31, 1998 would have been approximately $68.4 million, or
approximately $4.15 per share. This represents an immediate dilution of
approximately $11.35 per share to investors purchasing shares at the initial
public offering price. The following table illustrates this per share dilution:

    The selected historical financial data of (i) CRC Press, Inc. (the
"Predecessor") as of and for the years ended December 31, 1995 and 1996 and (ii)
the Company as of and for the year ended December 31, 1997 and as of and for the
three months ended March 31, 1998 have been derived from their respective
audited financial statements. The selected historical financial data of the
Predecessor as of and for the years ended December 31, 1993 and 1994 is derived
from its accounting records and has not been audited. The selected historical
financial data as of and for the three months ended March 31, 1997 has been
derived from unaudited financial statements, which in the opinion of management
includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair presentation of the results for the interim period. The
acquisition of the Predecessor and all other acquisitions by the Company were
accounted for using the purchase method of accounting. The Company acquired St.
Lucie Press on January 13, 1997, Auerbach on June 5, 1997 and MicroPatent on
July 2, 1997. The results of operations of these businesses are included in the
Company's results from their respective dates of acquisition and are not
included at all in the Predecessor's results. Accordingly, certain of the
historical financial data of the Predecessor are not comparable to those of the
Company. The selected historical financial data should be read in conjunction
with, and are qualified by reference to, "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and the financial statements
and notes thereto included elsewhere in this Prospectus.

- ------------------------
 
   
(1) In conjunction with the acquisition and reorganization of CRC Press and
    other businesses and certain compensation issues, the Company recorded
    significant adjustments in 1997 and early 1998, which are not expected to
    continue in the future. These adjustments (the "Adjustments") reduced
    revenues by $4,017 and increased expenses by $4,013, and therefore reduced
    net income by $8,030, for the year ended December 31, 1997. The Adjustments
    reduced revenue by $693 and $54 and increased expenses by $1,968 and $146,
    and therefore reduced net income by $2,661 and $200, for the three month
    periods ended March 31, 1997 and March 31, 1998, respectively. The
    Adjustments affecting revenues were required by purchase accounting in
    connection with the acquisitions of CRC Press and MicroPatent and reflect
    the revaluation of acquired deferred subscription revenues based on the cost
    to fulfill subscriptions. This revaluation is a non-cash adjustment which
    reduces revenues in the twelve months following acquisition. The Adjustments
    affecting expenses relate to: severance and reorganization costs from the
    consolidation of certain functions and reductions in workforce; special
    bonuses granted to an officer; contingent compensation paid to an officer of
    a subsidiary; and certain additional purchase accounting-related
    adjustments. Historical operating loss and EBITDA for the year ended
    December 31, 1997 of ($4,663) and $1,444, respectively, include the effect
    of the Adjustments of $8,030.
    
 
(2) Revenues for the three months ended March 31, 1997 and the year ended
    December 31, 1997 includes an initial stocking order by a new international
    distributor aggregating $3,307, which is not expected to continue in the
    future.
 
(3) Operating expenses for the year ended December 31, 1995 include $10,727 of
    restructuring and one-time charges. Operating expenses for the year ended
    December 31, 1996 include an impairment in the value of goodwill and other
    intangible assets of $10,666. This charge represents the amount by which the
    recorded value of the assets exceeded the proceeds from the sale of the
    business.
 
(4) Income taxes of the Company are not significant. Prior to the Exchange, the
    Company was a limited liability company and, accordingly, was not subject to
    U.S. federal or certain state income taxes. Income tax (benefits) expenses
    of the Predecessor were ($4,902) and $170, respectively, for the years ended
    December 31, 1995 and 1996. No historical earnings per share or share data
    are presented as the Company does not consider such historical data
    meaningful.
 
(5) Depreciation and amortization include balances related to property and
    equipment, intangible assets and pre-publication costs incurred in book
    publishing operations. Capital expenditures include property and equipment
    and pre-publication costs.
 
(6) For details of operating, investing and financing activities, see the
    Company's Consolidated Statements of Cash Flow for the year ended December
    31, 1997 and for the three months ended March 31, 1998, included elsewhere
    in this Prospectus.
 
(7) "EBITDA" is defined as income before interest expense/income, income taxes,
    depreciation and amortization. EBITDA is not a measure of performance under
    GAAP and should not be considered in isolation or as a substitute for net
    income, cash flow from operations or other income or cash flow data prepared
    in accordance with GAAP. Items excluded from the calculation of EBITDA are
    significant components in understanding and evaluating the Company's
    financial performance. While EBITDA should not be considered as a measure of
    profitability or liquidity, the Company understands that EBITDA is
    customarily used in evaluating the equity value of publishing companies. The
    EBITDA measure presented herein may not be comparable to similarly titled
    measures of other companies.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITIONS AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
FINANCIAL STATEMENTS AND NOTES THERETO AND THE OTHER FINANCIAL INFORMATION
APPEARING ELSEWHERE IN THIS PROSPECTUS.
 
OVERVIEW
 
    The Company is an information publisher that provides print and electronic
information to end-users in the STM and professional markets and electronic
access to intellectual property databases for end-users in the patent and
trademark markets. The Company currently sells over 3,000 individual book titles
and publishes approximately 300 new books each year. The Company also offers
multiple subscription products and services, including 20 journals, eight
newsletters, 16 annual handbooks and several comprehensive information guides
that are available in print and electronic formats. The Company offers its
intellectual property databases on CD-ROM and through the Internet.
 
    The Company operates in attractive niche publishing markets where it
provides essential information to professional and academic end-users. These
markets have supported consistent price increases over the past decade due to
the critical nature of the content. The markets for STM and professional
publishing and intellectual property information are growing and provide a
foundation for organic revenue growth and attractive fold-in acquisition
opportunities. The Company may enter additional niche markets that have these
attractive characteristics, such as healthcare information, regulatory
information and technology-related information.
 
    The Company's principal sources of revenues are book publishing sales,
subscription service sales and sales of patent and trademark information.
Through CRC Press (which includes St. Lucie Press and Auerbach), the Company
generates revenues from the sale of books and subscription products (72% and
28%, respectively, of total CRC Press revenues in the first quarter of 1998).
Revenues from books and related costs of sales are recognized when the product
is shipped to the customer. For products sold with a right of return, revenues
are recognized net of a provision for estimated returns. CRC Press's
subscription products target end-users with essential information and represent
a stable source of revenues. For example, aggregate renewal rates of the
Company's journals approximated 85% in 1997. The Company realizes significant
liquidity benefits from subscription revenues as cash is generally received in
advance of shipment. Revenues from subscription products are deferred and
recognized as revenues once the product is shipped. Further, the Company
believes that its book and subscription titles generate significant recurring
demand. For example, while the Company published approximately 285 frontlist
titles in 1997, it had a backlist of nearly 3,000 titles which accounted for
approximately 68% of the Company's total book publishing revenues in 1997.
Through MicroPatent, the Company generates revenues from CD-ROM subscriptions,
Internet-based services, and other products including database sales of
historical and customized patent information (35%, 34% and 31%, respectively, of
total MicroPatent revenues in the first quarter of 1998). The Company expects
that new publishing media, such as the Internet, will grow in significance in
the future. Of the Company's total revenues of $10.7 million for the first
quarter of 1998, 83% and 17% were derived from CRC Press and MicroPatent,
respectively.
 
    The Company's cost of sales are comprised principally of printing and
binding costs, amortization of plant costs and royalties paid to authors.
Printing and binding costs, which represented 26% of revenues for the first
quarter of 1998, are paid to third parties that print or produce the Company's
book products on a contract basis and include the costs of paper purchased by
those third parties. Plant costs include design and other pre-publication costs.
These costs are capitalized and charged to expense over a four-year period
following the release of the applicable book using an accelerated amortization
method. The Company's payments to its authors and editors do not involve
substantial up-front expense. Royalty payments are variable costs directly
associated with book sales.
 
    Operating expenses, which represented approximately 69% of the Company's
revenues for the first quarter of 1998, include selling, general and
administrative expense and related costs (39%), direct mail marketing costs
(19%) and amortization of intangible assets (13.4%). Selling, general and
administrative
 
                                       20
<PAGE>
expense includes wages and related costs, rent, fulfillment and commissions.
Direct mail expense is driven by the cost to produce each page, the number of
pages produced and mailing expense. In 1997, the Company mailed in excess of
800,000 pieces of direct mail per month. The aggregate cash consideration paid
by the Company to acquire its businesses in 1997 of $30.8 million was allocated
primarily to intangible assets having a gross book value of $24.6 million. The
amortization of these assets, as well as amortization from future acquisitions,
will impact operating results.
 
IMPACT OF ACQUISITIONS AND OUTLOOK
 
    The Company was organized in December 1996 and, since its inception, has
grown principally through acquisitions. The Company has sought acquisitions in
attractive niche markets where opportunities exist to organically grow the
acquired companies' revenues and profitability and to achieve operating
efficiencies. The Company continues to actively seek acquisitions that
management believes will further its growth and operating strategies. As the
Company acquires additional companies, its sales mix, market focus, cost
structure and operating leverage may change significantly. Consequently, the
Company's historical and future results of operations reflect and will reflect
the impact of acquisitions, and period-to-period comparisons may not be
meaningful in certain respects. For example, historical information for the
Predecessor and other acquired companies prior to their acquisitions reflect the
acquired companies' prior management and cost structure. In addition, as
described below, historical information for companies subsequent to their
acquisition may include integration and other costs that are not expected to
continue in the future.
 
   
    In 1997 and early 1998, the Company recorded the Adjustments in conjunction
with the acquisition and reorganization of the Predecessor and other businesses,
as well as certain compensation matters. The Adjustments reduced revenues and
operating loss of $34.9 million and ($4.7) million for 1997 by approximately
$4.0 and $8.0 million, respectively. Management does not expect these items to
continue in the future, although other issues may arise from future
acquisitions. See "Selected Historical Financial Data."
    
 
    The Company's results of operations for the fiscal quarter in which the
Offering is consummated will be adversely affected by the payment of
approximately $1.0 million in cash and shares of Common Stock as incentive
payments to Dennis Buda. See "Management--Employment Agreements."
 
   
    The Company is in discussions to acquire two STM product lines located in
the United Kingdom for a price of approximately $4.0 million. No definitive
agreements have been signed, and there can be no assurance that such transaction
will be consummated.
    
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31, 1997
 
    REVENUES.  Revenues increased by $2.0 million, or 23.3%, from $8.7 million
to $10.7 million. Auerbach, acquired in June 1997, and MicroPatent, acquired in
July 1997, contributed $2.9 million to revenues in the first quarter of 1998.
Domestic book sales increased by $2.2 million and the Adjustments resulted in an
increase of $0.6 million. These increases were partially offset by lower
international book sales of $3.8 million, due primarily to the initial stocking
order received in the first quarter of 1997.
 
    COST OF SALES.  Cost of sales increased by $0.2 million, or 7.1%, from $2.7
million to $2.9 million. As a percentage of revenues, cost of sales declined
from 30.7% to 26.6%. Auerbach and MicroPatent contributed $0.7 million to cost
of sales in the first quarter of 1998. Excluding the impact of such
acquisitions, cost of sales declined by $0.5 million due to the reduction in
international revenues, while other costs remained relatively consistent.
 
    OPERATING EXPENSES.  Operating expenses increased by $1.4 million, or 23.6%,
from $5.9 million to $7.3 million due primarily to operating expenses at
Auerbach and MicroPatent of $1.5 million. Excluding the impact of the
acquisitions, operating expenses decreased by $0.1 million. Expenses associated
with the
 
                                       21
<PAGE>
Adjustments decreased by $1.8 million, offset by increases in amortization of
intangible assets of $0.9 million and increases in other expenses of $0.8
million, including higher direct mail marketing costs.
 
    NET INCOME.  Net income increased by $0.6 million from less than $0.1
million to $0.6 million due to the factors described above.
 
    EBITDA.  EBITDA increased by $1.5 million, or 140.1%, from $1.0 million to
$2.5 million due to increased operating income of $0.5 million and the fact that
depreciation and amortization charged against operating income increased by $1.0
million for the three months ended March 31, 1998. The ratio of EBITDA as a
percentage of revenues increased from 11.8% to 22.9%.
 
COMPANY YEAR ENDED DECEMBER 31, 1997 COMPARED TO PREDECESSOR YEAR ENDED DECEMBER
  31, 1996
 
    REVENUES.  Revenues increased by $6.0 million, or 20.9%, from $28.9 million
to $34.9 million. St. Lucie Press, acquired in January 1997, Auerbach and
MicroPatent (the "1997 Acquisitions") contributed $8.3 million of revenues in
1997. Additionally, international book sales increased by $3.6 million,
primarily due to the initial stocking order received in the first quarter of
1997. These increases were partially offset by reduced revenues of $4.0 million
related to the Adjustments and other decreases of $1.9 million related primarily
to lower domestic book sales.
 
    COST OF SALES.  Cost of sales increased by $2.2 million, or 24.1%, from $9.3
million to $11.5 million. The 1997 Acquisitions contributed $2.4 million to cost
of sales in 1997. The Adjustments caused an increase of $0.4 million and, as a
result, increased cost of sales as a percentage of revenues. These increases
were partially offset by reduced costs of $0.6 million, primarily due to a
decrease in book production costs. Excluding the Adjustments, cost of sales as a
percentage of revenues decreased from 32.1% to 28.5% due primarily to lower
amortization of plant costs, as well as reductions in printing and binding costs
as a percentage of revenues.
 
    OPERATING EXPENSES.  Operating expenses decreased by $1.6 million, or 5.5%,
from $29.6 million to $28.0 million due to the impairment of intangible assets
of $10.7 million recorded in 1996 and a reduction in selling, general and
administrative expenses of $2.1 million, primarily related to lower wages, rent
and fulfillment costs. These decreases were partially offset by expenses of $5.7
million from the 1997 Acquisitions, expenses of $3.6 million related to the
Adjustments and $1.9 million of charges, due to the amortization of intangible
assets.
 
    OPERATING INCOME/LOSS.  The operating loss decreased by $5.4 million, or
53.7%, from ($10.1) million to ($4.7) million due to operating income (excluding
the amortization of intangible assets) from the 1997 Acquisitions of $0.6
million, an improvement in operating income of $4.0 million and an increase of
$10.7 million due to the impairment of intangibles recorded in 1996. These
increases were offset in part by an $8.0 million decrease resulting from the
Adjustments and a decrease of $1.9 million from higher amortization of
intangible assets.
 
    INTEREST EXPENSE.  Interest expense decreased by $0.9 million, or 87.5%,
from $1.0 million to $0.1 million due to reduced long-term obligations of CRC
Press, which had previous borrowings from its parent, The Times Mirror Company.
 
    NET LOSS.  The net loss decreased by $6.3 million, or 56.3%, from ($11.2)
million to ($4.9) million due to the operating income changes described above,
decreased interest expense and a decrease in income tax expense of $0.2 million.
 
    EBITDA.  EBITDA increased by $6.7 million, or 127.5%, from ($5.3) million to
$1.4 million. Excluding the Adjustments, EBITDA would have been $9.5 million, or
24.4% of revenues. For the year ended December 31, 1996, excluding the
impairment in intangible assets, EBITDA would have been $5.4 million, or 18.7%
of revenue.
 
                                       22
<PAGE>
PREDECESSOR YEAR ENDED DECEMBER 31, 1996 COMPARED TO PREDECESSOR YEAR ENDED
  DECEMBER 31, 1995
 
    REVENUES.  Revenues decreased by $3.2 million, or 10.0%, from $32.1 million
to $28.9 million due primarily to a $2.6 million decrease in international book
sales, largely in Asia. Domestic book sales declined by $0.4 million due to a
decreased publishing schedule.
 
    COST OF SALES.  Cost of sales declined by $2.1 million, or 18.5%, from $11.4
million to $9.3 million. As a percentage of revenues, cost of sales declined
from 35.5% to 32.1% primarily due to lower book publishing revenues, which
resulted in lower printing and binding costs, and decreased amortization of
plant costs.
 
    OPERATING EXPENSES.  Operating expenses decreased by $3.8 million, or 11.3%,
from $33.5 million to $29.7 million due to restructuring costs of $10.7 million
recorded in 1996, reduced provisions for book returns and bad debts and
decreased employee related costs in editorial and administrative areas. These
decreases were partially offset by a $10.7 million impairment of intangible
assets recorded in 1997.
 
    OPERATING LOSS.  The operating loss decreased by $2.7 million, or 21.1%,
from ($12.8) to ($10.1) million due to lower operating expenses, partially
offset by lower gross profits resulting from the decline in revenues. The 1996
restructuring charges of $10.7 million were offset by the 1997 impairment of
intangible assets of $10.7 million.
 
    INTEREST EXPENSE.  Interest expense declined by $0.3 million, or 18.6%, from
$1.3 million to $1.0 million due to lower average intercompany borrowings.
 
    NET LOSS.  The net loss increased by $2.0 million, or 21.7%, from ($9.2)
million to ($11.2) million due primarily to increased income tax expenses of
$5.1 million. This increase was partially offset by the operating income
improvements discussed above.
 
    EBITDA.  EBITDA increased by $1.8 million, or 25.4%, from ($7.1) million to
($5.3) million due to higher operating income, partially offset by decreased
depreciation and amortization.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Historically, the financing requirements of the Company have been funded
through cash generated by operating activities and capital contributions from
the Initial Stockholders. The financing requirements of CRC Press prior to its
acquisition by the Company were funded primarily through intercompany loans and
advances from its parent, The Times Mirror Company.
 
    Cash and cash equivalents totaled $9.8 million at March 31, 1998 and $10.3
million at December 31, 1997. Excluding cash, the Company had a working capital
deficit of $5.7 million at March 31, 1998 due primarily to the inclusion of $8.2
million of deferred subscription revenues, a non-cash obligation. Since the
Company receives subscription payments in advance, the Company's existing
operations are expected to maintain very low or negative working capital
balances, excluding cash.
 
    Cash generated by operating activities was $1.1 million for the three months
ended March 31, 1998 derived from net income of $0.6 million plus non-cash
charges of $1.8 million less an increase in operating assets, net of liabilities
of $1.3 million. This increase in operating assets and liabilities was primarily
due to payments associated with the Adjustments. Cash generated by operating
activities for the year ended December 31, 1997 was $8.6 million derived from
the net loss of ($4.9) million plus non-cash charges of $7.2 million plus a
decrease in operating assets, net of liabilities of $6.3 million.
 
    Cash used by investing activities was $0.5 million for the three months
ended March 31, 1998 due to capital expenditures, including pre-publication
costs, of $0.3 million and acquisition costs of $0.2 million. Cash used for
investing activities for the year ended December 31, 1997 was $33.6 million,
including acquisitions of businesses totaling $30.8 million and capital
expenditures, including plant costs, of $2.8 million. The Company's existing
operations are not capital intensive.
 
    Cash used for financing activities was $1.1 million for the three months
ended March 31, 1998 representing payment on debt. Cash provided by financing
activities was $35.3 million for the year ended
 
                                       23
<PAGE>
December 31, 1997, including $33.5 million of capital contributions from the
Initial Stockholders and a net increase in debt of $1.8 million.
 
    The Company has financed all acquisitions to date through capital
contributions from the Initial Stockholders. The Company had $1.0 million of
debt at March 31, 1998 under a revolving credit facility, which was subsequently
repaid. The Company currently does not maintain a working capital facility but
believes that, if needed, one would be available at market rates.
 
    The Company believes that net cash provided by operations, together with
cash on hand and other available sources of funds, will be sufficient to fund
the cash requirements of its existing operations. Excluding acquisition
activity, the Company does not expect to use the proceeds of the Offering to
fund operations. The Company currently has no commitments for material capital
expenditures. However, future operating requirements and capital needs will be
subject to economic conditions and other factors, many of which are beyond the
Company's control. See "Risk Factors."
 
    The Company will use net proceeds from the Offering for general corporate
purposes, including acquisitions. The Company does not have any agreements,
arrangements or understandings with respect to any prospective material
acquisitions. Pending such uses, the net proceeds will be invested in
short-term, investment grade securities.
 
SEASONALITY
 
    The Company's business is mildly seasonal, with revenues typically reaching
slightly higher levels during the third and fourth quarters of each calendar
year, based on historical publication schedules. In 1997, on a pro forma basis,
24% of the Company's revenues were generated during the fourth quarter, with the
first, second and third quarters accounting for 29%, 23% and 24% of revenues,
respectively. The first quarter of 1997 was uncharacteristically high due to an
initial stocking order from a new international distributor. Excluding this
order, first through fourth quarter revenues were 22%, 25%, 27% and 26%,
respectively. In addition, the Company may experience fluctuations in revenues
from period to period based on the timing of acquisitions and new product
launches.
 
EFFECTS OF INFLATION
 
    The Company believes that inflation has not had a material impact on the
results of operations presented herein.
 
ACCOUNTING PRONOUNCEMENTS
 
    In 1997, the Financial Accounting Standards Board (FASB) issued SFAS No.
129, DISCLOSURE OF INFORMATION ABOUT CAPITAL STRUCTURE, and SFAS No. 130,
REPORTING COMPREHENSIVE INCOME. SFAS No. 129 contains no change in the Company's
disclosure requirements, and SFAS No. 130 has no impact on the Company's
financial position or results of operations.
 
    In June 1997, the FASB issued SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN
ENTERPRISE AND RELATED INFORMATION. The Company adopted this statement and
determined that the new standard does not have any impact on the Company's
financial statements.
 
YEAR 2000 ISSUE
 
    The year 2000 issue is the result of computer programs using two digits
rather than four to define the applicable year. As a result, those computer
programs have time-sensitive software that recognizes a date using "00" as the
1900 rather than the year 2000. This error could cause a system failure or
miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities.
 
    The Company has developed a plan to modify its information technology to be
ready for the year 2000 and has begun converting critical data processing
systems. The Company expects the projects to be completed by early 1999 at a
cost of less than $100,000. The estimate includes internal costs, but excludes
the costs to upgrade and replace systems in the normal course of business. The
Company does not expect these projects to have a significant effect on
operations. As of March 31, 1998, there have been no significant expenses
incurred. See "Risk Factors--Risks Related to the Year 2000."

                                    BUSINESS
 
OVERVIEW
 
   
    The Company is an information publishing business focused on providing
essential information to professional and academic end-users in attractive niche
markets. The Company was formed to capitalize on management's experience in
acquiring information publishing businesses and then increasing profitability
through a combination of organic revenue growth and improved operating
efficiencies. To date, the Company has acquired information publishing
businesses in the following niche markets: STM and professional through CRC
Press; and intellectual property through MicroPatent. For the year ended
December 31, 1997, the Company had revenues, net loss and EBITDA of $34.9
million, ($4.9) million and $1.4 million, respectively. These figures reflect
the Adjustments, which reduced revenues by $4.0 million and net income and
EBITDA by $8.0 million.
    
 
    CRC Press, acquired in January 1997 from The Times Mirror Company, is a
mid-sized STM and professional publisher with leading positions in several
attractive niche markets. CRC Press, with a 95-year history, has highly regarded
brand names and publishes some of the most recognizable STM titles in their
respective fields, including THE HANDBOOK OF CHEMISTRY AND PHYSICS (currently in
its 79th edition) and STANDARD MATHEMATICAL TABLES AND FORMULAE. In the first
half of 1997, two fold-in acquisitions were completed and combined with CRC
Press: St. Lucie Press, a publisher of professional titles; and Auerbach, a
provider of technology-oriented print and electronic subscription-based
products, which was acquired from Thomson. For the three months ended March 31,
1998, CRC Press contributed approximately 83% of the Company's revenues.
 
    MicroPatent, acquired in July 1997, is a leading source of intellectual
property information products and services. Its high-quality patent and
trademark databases are used extensively by legal and research professionals and
corporations. The Internet, MicroPatent's fastest-growing distribution channel,
accounted for 34% of its total revenue in the first quarter of 1998, as compared
to 14% in the first quarter of 1997. The Company believes that its profitable
PATENTWEB service is among the most comprehensive intellectual property
information services on the Internet. For the three months ended March 31, 1998,
MicroPatent contributed approximately 17% of the Company's revenues.
 
MANAGEMENT
 
   
    The Company was formed in December 1996 by Mason P. Slaine and Warburg
Pincus. Mr. Slaine, the Company's President and Chief Executive Officer, has
more than 15 years of experience in the information publishing industry in both
corporate and entrepreneurial environments. From 1994 to 1996, he served as
President of Thomson Financial, a unit of Thomson which is a leading provider of
financial information, research, analysis and software products worldwide.
    
 
    Vincent A. Chippari, the Company's Executive Vice President and Chief
Financial Officer, has extensive experience in information publishing, business
management, consulting and finance, including seven years in various senior
level operating and financial capacities with Thomson. Messrs. Slaine and
Chippari are complemented by strong operating management. Dennis Buda, President
of CRC Press, and Steven Wolfson, President of MicroPatent, each have more than
20 years of experience in the information publishing industry. See "Executive
Officers and Directors." Upon consummation of the Offering, the executive

GROWTH AND OPERATING STRATEGY
 
    The principal elements of the Company's growth strategy are to (i) acquire
businesses in attractive niche markets, (ii) organically grow revenues and
profit, (iii) improve operating efficiencies and (iv) attract and retain
superior management.
 
    ACQUIRE BUSINESSES IN ATTRACTIVE NICHE MARKETS.  The Company actively seeks
to identify and acquire information publishing businesses with attractive
market, product and customer characteristics. The Company targets professional
and academic end-users who have a critical need to keep abreast of current
developments in their particular fields. While the Company continually develops
and introduces new products, the majority of the Company's revenues are
generated from recurring sources, such as subscriptions and backlist sales. The
Company believes that markets in which information is critical to success, such
as the STM market served by the Company, have supported consistent price
increases over the past decade. The Company's products and services are
generally not sensitive to pricing pressures or adverse economic conditions.
Examples of additional niche markets that the Company may target include
business information, healthcare information, regulatory information and
technology-related information. Upon the expiration of Mr. Slaine's non-compete
agreement with Thomson at the end of 1999, the Company may also pursue
opportunities in financial information publishing. See "Management--Slaine
Non-competition Agreement."
 
    ORGANICALLY GROW REVENUES AND PROFIT.  The Company seeks to acquire
information publishing businesses with significant short- and long-term growth
prospects. The Company's strategy is to acquire valuable content and leverage
such content across new distribution platforms and through expansion of product
lines. For example, the Company has launched new electronic versions of
successful print products, increased sales of core products based on new
distribution agreements, began Internet delivery of products and launched new
products targeting segments of its existing customer base.
 
    IMPROVE OPERATING EFFICIENCIES.  The Company seeks to improve operating
efficiencies by combining administrative functions, eliminating redundant
facilities, negotiating more favorable contract terms with suppliers,
implementing systems improvements, and upgrading management. In addition, the
Company seeks to leverage its infrastructure by acquiring companies or product
lines which can be supported by its existing operations. To date, CRC Press has
acquired two such companies, St. Lucie Press and Auerbach, as well as a line of
engineering titles from Krause Communications and the McGee line of business
titles.
 
    ATTRACT AND RETAIN SUPERIOR MANAGEMENT.  The Company seeks to employ
professional management with substantial information publishing expertise, both
in entrepreneurial and corporate settings. The Company's philosophy is to
provide operating units with significant decision-making authority, so that key
operating policies are made close to the Company's customers and operations.
This enables the Company to attract superior entrepreneurial talent who can grow
the business by capitalizing on market opportunities.
 
STRATEGY IMPLEMENTATION
 
    Since the acquisitions of CRC Press and MicroPatent, the Company has
successfully executed its growth and operating strategy and significantly
improved the financial performance of these businesses. In 1996, prior to its
acquisition by the Company, CRC Press had an operating profit margin of
approximately 6%, excluding the impairment and amortization of intangibles. In
the first quarter of 1998, CRC Press increased its operating profit margin to
approximately 15%, excluding the amortization of intangibles. Similarly,
MicroPatent's operating profit margin was approximately 2%, excluding the
amortization of intangibles, in the year prior to acquisition. In the first
quarter of 1998, operating profit was increased to 32%, excluding the
amortization of intangibles.
 
    ORGANIC GROWTH.  At CRC Press, the list of new publications or new editions
of prior publications ("frontlist") of 285 titles in 1997 is expected to grow to
approximately 300 new titles in 1998 and
 
                                       26
<PAGE>
approximately 350 titles in 1999. The Company has also taken steps to increase
its international sales by entering into a global distribution agreement
(excluding North America) with Springer-Verlag GmbH & Co. KG
("Springer-Verlag"), a significant Europe-based scientific and technical
publisher. In addition, the Company has leveraged well-established titles such
as THE HANDBOOK OF CHEMISTRY AND PHYSICS and STANDARD MATHEMATICAL TABLES AND
FORMULAE by publishing them in electronic format, which is expected to expand
their reach and application.
 
    MicroPatent's revenue growth has also accelerated significantly since its
acquisition by the Company, with revenues increasing 23% in the nine months
following acquisition over the comparable period of the prior fiscal year. Such
growth has been driven largely by Internet product offerings. Revenues from
Internet-based patent information grew more than 150% from the second quarter of
1997 to the first quarter of 1998. In addition, in the first quarter of 1998,
revenues generated by all Internet products rose to 34% of MicroPatent's total
revenues, as compared to 14% in the first quarter of 1997.
 
    OPERATING IMPROVEMENTS.  The overall cost base of CRC Press has been reduced
through an improvement in operating procedures. For example, plant costs per
page, which include design and other pre-production costs for books published,
decreased by approximately 45% between 1996 and 1997 and have been further
reduced in 1998. Additionally, direct marketing costs per piece were reduced by
more than 30% from 1996 to 1997 without any revenue impairment.
 
    At MicroPatent, significant investments were made in its website to expand
web-based content and to enhance existing technology. This investment has led to
increased Internet reliability and speed which has helped spur customer demand.
In addition, since the Company acquired MicroPatent, overall cost levels have
decreased. In particular, in the year prior to acquisition, operating expenses,
excluding the amortization of intangibles, approximated 62% of revenues. In the
first six months under the Company's ownership, these expenses were reduced to
52% of revenues.
 
    FOLD-IN ACQUISITIONS.  Since the acquisition of CRC Press, the Company has
successfully completed two fold-in acquisitions: (i) St. Lucie Press, a
publisher of professional titles; and (ii) Auerbach, a provider of
technology-oriented print and electronic subscription-based products. The
Company also acquired a line of engineering titles from Krause Communications
and the McGee line of business titles. These acquisitions expanded the Company's
product offerings and increased profitability by leveraging its existing
infrastructure.
 
    MANAGEMENT.  The Company installed a new senior management team at CRC Press
within three months after its acquisition, which substantially altered the
editorial, production and marketing processes at the Company. These executives
have an average of 16 years of publishing industry experience.
 
    At MicroPatent, through internal promotion and recruitment, the Company
installed a new CEO, hired management to build a trademark database and hired
senior sales and marketing executives.
 
STM AND PROFESSIONAL PUBLISHING
 
    MARKET
 
    The Company provides information in selected niches of the broad STM and
professional market. The STM and professional market is global in nature and has
experienced consistently solid growth with total market revenues expanding from
$2.1 billion in 1986 to $4.0 billion in 1996. Management believes this market
will continue to expand as the need for information continues to increase based
on factors such as: constantly increasing complexity within STM and professional
research; globalization of the STM and professional market; and technological
advances which enable greater distribution of content.
 
    The Company targets end-users, such as professionals and academics, with
high-end specialized reference information. The Company products are targeted
towards areas with a significant number of
 
                                       27
<PAGE>
end-users including chemists, engineers, mathematicians, technology
practitioners and environmental scientists. These end-users are generally not
price sensitive due to the critical nature of the content.
 
    PRODUCTS
 
    CRC Press is a medium-sized publisher with strong market positions in
chemistry, mathematics, engineering, food science, environmental sciences and
key areas of technology. CRC Press's products are divided into two broad
categories: book publishing (which includes electronic versions and
distribution) and subscription services. In the first quarter of 1998, book
publishing and subscription services generated 72% and 28%, respectively, of CRC
Press's revenues.
 
    BOOK PUBLISHING.  CRC Press publishes some of the most recognizable science
titles in their respective fields, including THE HANDBOOK OF CHEMISTRY AND
PHYSICS (currently in its 79th edition) and STANDARD MATHEMATICAL TABLES AND
FORMULAE. CRC Press has an extensive backlist of nearly 3,000 titles, which
generates substantial recurring demand. In 1996 and 1997, the backlist
contributed 66% and 68% of total book publishing revenues, respectively. In
addition, CRC Press has a strong and active frontlist publishing program. In
1997, CRC Press published approximately 285 frontlist titles. Publishing levels
have increased since the Company acquired CRC Press with 300 titles scheduled
for publication in 1998 and approximately 350 scheduled for publication in 1999.
CRC Press's book publishing focuses on the following areas:
 
        Life Sciences.  CRC Press-Registered Trademark- is a well-recognized
    brand in life sciences and publishes with a technical focus in areas
    including neurology, biology, pathology, ecology, food technology, marine
    science and forensics. CRC Press published 103 titles in life sciences in
    1997 and has an active life sciences backlist of over 1,400 titles. In 1997,
    total life sciences sales represented 34% of Company's book publishing
    revenues. Some of CRC Press's leading titles in life sciences include CRC
    HANDBOOK OF HUMAN TOXICOLOGY, PRACTICAL HOMICIDE INVESTIGATION and PAIN
    MANAGEMENT.
 
        Engineering, Mathematics and Physical Sciences.  CRC Press has a strong
    franchise in engineering, mathematics and physical sciences based on leading
    titles, strong co-publishing relationships and a practitioner oriented
    approach. CRC Press published 83 titles in engineering, mathematics and
    physical sciences in 1997 and has a backlist of over 600 titles. In 1997,
    total engineering, mathematics and physical sciences revenues represented
    32% of Company's book publishing sales. CRC Press's strong titles include
    THE HANDBOOK OF CHEMISTRY AND PHYSICS (79th edition) and STANDARD
    MATHEMATICAL TABLES AND FORMULAE. In addition, the Company has a
    co-publishing arrangement with the Institute of Electrical and Electronic
    Engineers, a leading engineering society with over 120,000 members. This
    relationship gives the Company wide distribution for engineering titles and
    a competitive advantage in attracting engineering authors.
 
        Environmental Sciences.  The Company's Lewis Publishers-TM- imprint is
    one of the top publishers of environmental science books with titles in all
    areas including environmental chemistry, environment engineering, wetlands
    development, ecology and remediation. The Company published 54 environmental
    sciences titles in 1997 and has a backlist that includes over 600 titles. In
    1997, total environmental sciences sales represented 22% of the Company's
    book publishing revenues. Well-known environmental sciences titles include
    Manahan's ENVIRONMENTAL CHEMISTRY, REMEDIATION ENGINEERING: A DESIGN
    HANDBOOK, ENVIRONMENTAL ENGINEERING HANDBOOK and the United States Golf
    Association's ("USGA") LANDSCAPE RESTORATION HANDBOOK (a joint publication
    among CRC Press, the Audubon Society of New York State and the USGA).
 
        Business Publications.  The Company's St. Lucie Press-TM- imprint
    publishes books focusing on all areas of business, including management,
    human resources, manufacturing processes, finance and investment. St. Lucie
    Press's publications are targeted at high-level management, technical and
    analytic end-users through titles such as PRINCIPLES OF TOTAL QUALITY and
    CHIEF EXECUTIVE OFFICER PAY AND SHAREHOLDER VALUE. Additionally, the Company
    completed the complementary acquisition of the
 
                                       28
<PAGE>
    McGee line of titles, including TECHNICAL ANALYSIS OF STOCK TRENDS, which
    was integrated into CRC Press. CRC Press published 34 business publications
    in 1997 and has a backlist which includes approximately 100 titles. In 1997,
    total business publications sales represented 7% of the Company's book
    publishing revenues.
 
    SUBSCRIPTION PRODUCTS. The Company's subscription products focus on the
following areas:
 
        Technology Services.  The Company provides high-level information
    systems and information technology management products under its Auerbach
    imprint. Auerbach offers three journals, two newsletters, sixteen annual
    handbooks and eight information management guides available in print and
    CD-ROM. Auerbach is a technology publisher with over 20,000 subscriptions
    for its various products. Significant Auerbach titles include the JOURNAL OF
    INFORMATION SYSTEMS MANAGEMENT, EDP AUDIT CONTROLS, BUSINESS RESUMPTION
    PLANNING, HANDBOOK OF LOCAL AREA NETWORKS, HANDBOOK OF MIS MANAGEMENT and
    the AUERBACH INFORMATION MANAGEMENT SERIES (AIMS). Auerbach recently
    launched a successful newsletter, YEAR 2000 PRACTITIONER, and it has several
    newsletters and handbooks in development. Auerbach contributed approximately
    41% of CRC Press's pro forma 1997 subscription revenues, excluding the
    Adjustments.
 
        Newsletters.  The Company's Food Chemical News ("FCN") division serves
    the food and chemical industries with six newsletters and two comprehensive
    food chemical science guides, available in print and CD-ROM. FCN products
    command premium pricing and have aggregate renewal rates above 80%. Content
    is also available in electronic format, and the Company is actively pursuing
    site licensing and Internet opportunities. FCN's flagship product, FOOD
    CHEMICAL NEWS-REGISTERED TRADEMARK-, is a weekly newsletter tracking food
    policy and regulatory changes. It has been a leading source of information
    to the food industry for over 36 years. Additional products offered by FCN
    include PESTICIDE AND TOXIC CHEMICAL NEWS, WORLD FOOD NEWS and FOOD LABELING
    AND NUTRITION NEWS. FCN contributed approximately 37% of CRC Press's pro
    forma 1997 subscription revenues, excluding the Adjustments.
 
        Journals.  The Company currently publishes 17 subscription-based
    journals. Journals include both primary journals, such as the JOURNAL OF
    SOIL CONTAMINATION and OZONE SCIENCE AND ENGINEERING, which are vehicles for
    the publication of original research; and secondary journals in the Critical
    Review series. The journal program is concentrated in areas where the
    Company has strong book publishing programs and provides synergy with
    respect to marketing and editorial functions. In CRITICAL REVIEW journals,
    including titles such as CRITICAL REVIEWS IN ANALYTICAL CHEMISTRY and
    CRITICAL REVIEWS IN TOXICOLOGY, acknowledged experts summarize recent
    professional literature in important areas of science and technology. The
    Company recently launched a new primary journal, STRATEGIES IN ENVIRONMENTAL
    MANAGEMENT, and is actively developing journal content for Internet
    delivery. Aggregate renewal rates for the Company's journals approximated
    85%. Journals contributed approximately 21% of CRC Press's pro forma 1997
    subscription revenues, excluding the Adjustments.
 
    SALES, MARKETING AND DISTRIBUTION
 
    Direct response marketing is the primary method for selling the Company's
products. The Company has an in-house creative services and direct marketing
group which designs, manages, and produces cost-effective direct mail campaigns
and other promotional support programs. The Company utilizes its extensive
in-house lists of book buyers, supplemented by lists from professional societies
and list management companies. In 1997, the Company produced in excess of 1,000
promotional campaigns and mailed in excess of 800,000 direct mail pieces per
month on average. The cost per piece for direct mail has been reduced by over
30% since the Company acquired CRC Press. Direct mail, including textbook
adoptions, generated 31% of CRC Press's 1997 book revenues and the majority of
its subscription-based revenues.
 
    The Company uses a small, well-experienced sales force for professional book
sales to the Company's academic and specialty bookstores, wholesalers,
catalogers and associations, as well as sales of site licenses
 
                                       29
<PAGE>
to corporations and academic institutions. In the aggregate, these channels
provided 37% of the Company's 1997 book revenues. There is also an outbound
telesales group used primarily for new sales of Auerbach technology products.
 
    The Company uses several well-respected distributors for sales outside of
North America. The primary distributor for books is Springer-Verlag, a
significant Europe-based scientific and technical publisher with extensive
international marketing capabilities. International sales contributed 30% of the
Company's 1997 book revenues, 12% attributable to a non-recurring initial
stocking order from Springer-Verlag in the first quarter of 1997. In 1997,
Springer-Verlag accounted for approximately 18.7% of the Company's revenues.
 
    OPERATIONS
 
    The Company operates its business in an entrepreneurial manner that serves
to increase employee responsibility and accountability. The Company has
leveraged its long-standing relationships with acknowledged experts in its
existing markets and developed close relationships with acclaimed industry
leaders in new markets. These relationships provide the Company with experienced
authors and editors who are given increased responsibility for product
development and profitability. Currently, CRC Press employs approximately 40
editors who are responsible for proposing new publications, contacting and
signing new authors, managing each publication on a return-on-investment basis,
and managing product line growth and quality enhancement. The compensation of
editors is partially linked to the success of their respective product lines.
Similarly, authors are typically signed to royalty-based contracts that
compensate them based on the revenues of the applicable publications.
 
    The Company's strategy of increasing individual responsibility and
accountability has been applied to the in-house production process, as well.
Currently, CRC Press employs approximately 35 professionals to manage pre-press
production which includes copy-editing, type-setting, illustration, interior and
cover design, and the preparation of final output for the printer. Driven by
systems upgrades and several incentive-based bonus plans, CRC Press expects to
perform over 50% of pre-press production in-house in 1998, with external
production having negotiated rates comparable to its internal rate. In addition,
the production personnel oversee the printing and binding activities performed
by third-party printers. The Company conducts business with several different
printers and is not dependent on the services of any one printer in particular.
 
INTELLECTUAL PROPERTY INFORMATION SERVICES
 
    MARKETS
 
    The Company is a leading provider of intellectual property information
products and services. The Company estimates that the core components of the
intellectual property information markets, patents and trademarks, currently
exceed $500 million on a worldwide basis. These markets continue to grow as
usage of intellectual property information has expanded significantly in the
past decade fueled by factors such as: increased awareness of the value of
intellectual property as a corporate asset; greater enforcement of intellectual
property rights on a worldwide basis; more intellectual property filings, such
as European Community trademarks; and technological advances which enable
greater storage, searching and access to large databases. Management believes
these positive trends will continue.
 
    PRODUCTS
 
    The Company is a leader in selected niches of intellectual property markets,
specifically in the provision of patent information through the Internet,
corporate intranets and other electronic media, such as CD-ROM. The Company
collects primary source data from the world's major patent and trademark offices
and adds significant value through the development of vast integrated databases,
innovative product
 
                                       30
<PAGE>
delivery and sophisticated software for data searching and access. In addition,
the Company has recently launched its trademark information business and is
currently a growing provider in this market.
 
    The Internet is an important distribution mechanism for intellectual
property information and is MicroPatent's fastest growing channel. The Company
believes that its profitable PATENTWEB service is the most comprehensive
commercial intellectual property information service on the Internet. Internet
services range from individual payment for access to a single patent to
unlimited annual use plans for searching and downloading throughout a corporate
customer's site. Revenues from Internet-based patent information grew more than
150% from the second quarter of 1997 to the first quarter of 1998. In addition,
in the first quarter of 1998, revenues generated by all Internet products rose
to 34% of MicroPatent's total revenues.
 
    MicroPatent was also among the first providers of patent information on
CD-ROM. It offers both text and image products covering U.S., European and
Japanese information. The Company believes that its
PATENTIMAGES-REGISTERED TRADEMARK- products remain leading CD-ROM products in
the North American market. Patent CD-ROM subscriptions generated 35% of
MicroPatent's revenues in the first quarter of 1998. In addition to
subscriptions to databases of worldwide patent information, MicroPatent offers
databases of historical ("backfile") and current patent information, in standard
and custom formats, in multiple media. Backfile and custom product sales
generated 23% of MicroPatent's revenues in the first quarter of 1998.
 
    While the Company continues to expand both the content and functionality of
its patent products, it is also expanding rapidly into trademark information.
The Company launched a U.S. federal trademark database, MARKSEARCH PRO-TM-, and
now has trademark products available in CD-ROM and on the Internet through
TRADEMARKWEB-TM-. In the first quarter of 1998, trademark products, which are
included above in CD-ROM subscription and Internet revenues, generated 7% of
MicroPatent's revenues.
 
    The Company continues to develop its content and recently launched its
worldwide patent search service and MARKSEARCH PRO. Later this year, the Company
plans to introduce full-text searching on U.S. patents and several new
international databases, including content from the World Intellectual Property
Organization and the European Community. The Company is also expanding into new
markets through development of value-added trademark information products,
including a state trademark database which will be available on the Internet.
 
    SALES, MARKETING AND DISTRIBUTION
 
    The majority of MicroPatent's sales are made through an in-house sales force
with offices in the United States and the United Kingdom. Prospects are
identified through referrals from existing customers, referrals from patent and
trademark offices, leads from trade shows and information requests from sources
such as the Internet. Additional international sales are made through a network
of distributors. Renewals are generally made by mail with telephone follow-up.
 
    OPERATIONS
 
    The Company employs 12 people to produce and fulfill its patent and
trademark CD-ROM and customized information products. Source data is received
weekly from the U.S. Patent and Trademark Office and certain foreign patent and
trademark offices. The Company receives the data in various formats and media
and, through internal procedures using both proprietary and third-party
software, produces a master CD-ROM for each subscription product. An outside
vendor is used for CD-ROM replication and shipments to customers.
 
    Source data is continually added to the Company's numerous in-house
databases, which support its Internet-based products and services. These
databases, together with various support systems and product interfaces, are
maintained by a programming and research and development staff of four. These
software
 
                                       31
<PAGE>
development professionals, together with several technical support staff, create
and maintain the Company's various Internet products.
 
    Since its acquisition of MicroPatent, the Company has taken several
initiatives to improve operations. Significant investments made in MicroPatent's
website to expand web-based content and enhance existing technology have led to
increased reliability and speed. In addition, since the Company acquired
MicroPatent, overall cost levels have decreased. In particular, in the year
prior to acquisition, operating expenses (excluding amortization of intangibles)
approximated 62% of revenues. In the first six months under the Company's
ownership, these expenses were reduced to 52% of revenues.
 
COMPETITION
 
    The Company competes with a broad range of companies for the products and
services it offers. Although it provides information in competitive markets and
such competition is unlikely to diminish, the Company believes it can compete
successfully based on its well-established positions in niche markets, the
quality of its products, the breadth and depth of its content, continued product
innovation and efficient operations.
 
    STM information publishing is a large market with numerous competitors.
While there is competition for sales in a given area, products are generally
unique titles sold on an individual basis. The Company must also compete for the
signing of noted authors. The Company's primary STM competitors include John
Wiley, McGraw-Hill and Academic Press, a unit of Harcourt General. These
competitors are larger and have greater financial resources than the Company. In
addition there are numerous small publishers that compete with the Company.
 
    The Company also competes with other sellers of intellectual property
information. Thomson owns Derwent and Thomson & Thomson, large competitors in
patents and trademarks, respectively. In addition to direct sales, these
companies offer content through on-line services such as Dialog, which combines
this information with other business information. Lastly, there are several
low-cost or free intellectual property services offered by large
technology-oriented companies, such as IBM and EDS, and certain national and
international patent and trademark offices. These services have not had a
significant negative impact on the Company to date, due to the Company's ability
to differentiate itself through adding value by making data easily accessible
and customizing products for specific client needs.
 
INTELLECTUAL PROPERTY
 
    The Company regards its trademarks, copyrights, trade secrets and similar
intellectual property as valuable assets and relies upon trademark and copyright
laws, as well as confidentiality agreements with its employees and others, to
protect its rights. The Company pursues the registration of its material
trademarks and copyrights in the United States and, depending upon use, in
certain other countries. The Company believes it owns or licenses all
intellectual property rights necessary to conduct its business. To the best of
the Company's knowledge, there are no threatened or pending legal proceedings or
claims related to the Company's intellectual property that are likely to have,
individually or in the aggregate, a material adverse effect on the Company's
business, financial condition or results of operations.
 
FACILITIES
 
    The Company leases office space in East Haven, Connecticut; Washington,
D.C.; Boca Raton, Florida; New York, New York; and London, England under leases
expiring in 2001; 2002; 1998 and 2006; 2002 and 2005; and quarterly,
respectively. The Company contracts with a third party for warehousing and
distribution services at a Lynn, Missouri facility. The Company does not own any
real property. The Company believes that its properties, taken as a whole, are
in good operating condition and are suitable and adequate for the Company's
current business operations, and that suitable additional or alternative space
will be available at commercially reasonable terms for future expansion.
 
                                       32
<PAGE>
EMPLOYEES AND LABOR RELATIONS
 
    As of March 31, 1998, the Company had approximately 240 employees. No
employees are covered by collective bargaining agreements with labor unions. The
Company believes that relations with its employees are good. The Company's
policy is to motivate its key employees through grants of stock options and
other incentive-based compensation. See "Management--1998 Stock Option Plan."
 
LITIGATION
 
    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. Certain of the other
investors in Rand have alleged that Mr. Slaine breached his fiduciary duty to
them and usurped corporate opportunities available to Rand by investing in the
Company and by participating in the acquisition by the Company of various
businesses. These investors have threatened to sue Mr. Slaine, have asserted
claims for damages and have requested that a constructive trust be established
for their benefit consisting of Mr. Slaine's interest in the Company and other
relief. Mr. Slaine denies such allegations and has indicated to the Company
that, if commenced, he intends to vigorously contest any such action brought by
these investors.
 
    In addition, the Company is involved in litigation that has arisen in the
ordinary course of business. None of these matters, either individually or in
the aggregate, is expected to have a material adverse effect on the Company's
financial condition or results of operations.
 
INSURANCE
 
    The Company maintains general liability and property insurance and an
umbrella and excess liability policy in amounts it considers adequate and
customary for a business of its kind. However, there can be no assurance that
future claims will not exceed insurance coverage.

SLAINE NON-COMPETITION AGREEMENT
 
    Pursuant to an employment and restrictive covenants agreement, dated April
1, 1994, between Mr. Slaine and an affiliate of Thomson, Mr. Slaine is generally
restricted from owning, engaging in or providing services to any business that
competes with the businesses of Thomson Financial. Thomson Financial is a
provider of financial information, research, analysis and software products.
These restrictions expire on December 31, 1999.
 
1998 STOCK OPTION PLAN
 
    The Company's 1998 Stock Option Plan (the "1998 Stock Option Plan") has been
adopted by the Board of Directors and the stockholders of the Company. The 1998
Stock Option Plan provides for the grant of non-qualified options ("NQOs") and
incentive stock options ("ISOs") as defined in Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"). The 1998 Stock Option Plan will
be administered by the Board of Directors of the Company, or, if designated by
the Board, the Compensation Committee of the Board. The Board believes that the
1998 Stock Option Plan is important to provide an inducement to obtain and
retain the services of employees of the Company and its subsidiaries and to
increase their proprietary interest in the Company's success.
 
    At present, all directors and full-time employees of the Company and its
subsidiaries, are eligible to participate in the 1998 Stock Option Plan. The
aggregate number of shares of Common Stock as to which stock options ("Options")
may be granted under the 1998 Stock Option Plan may not exceed 866,638 (assuming
an initial public offering price of $15.50 per share), subject to adjustment as
provided in the 1998 Stock Option Plan.
 
    Recipients of Options under the 1998 Stock Option Plan ("Optionees") are
currently selected by the Board, which has sole authority (i) to determine the
number of Options to be granted to such recipient, (ii) to prescribe the form or
forms of the Option Agreements, (iii) to adopt, amend or rescind rules and
regulations for the administration of the 1998 Stock Option Plan, (iv) to
construe and interpret the 1998 Stock Option Plan, (v) to determine the exercise
price of shares subject to Options, (vi) to determine the dates on which Options
become exercisable, (vii) to determine the expiration date of each Option and
(viii) to cancel any Option held with the express written consent of the
affected Optionee. Options granted under the 1998 Stock Option Plan will be
evidenced by a written Option agreement between each Optionee and the Company.
 
   
    The exercise price of the shares of Common Stock subject to Options are
currently fixed by the Board, in its discretion, at the time Options are
granted, provided that the per share exercise price of an ISO may not be less
than the fair market value of a share of Common Stock on the date of grant.
Options to purchase an aggregate of 409,617 shares under the 1998 Stock Option
Plan will be granted upon consummation of the Offering, assuming an initial
public offering price of $15.50 per share. Such Options are exercisable at a
price per share equal to the initial public offering price and vest in four
equal annual installments beginning on the first anniversary of the date of
grant, except that the Options to be granted to the Independent Directors and
certain executive officers have accelerated vesting schedules.
    
 
    Optionees will have no voting, dividend, or other rights as stockholders
with respect to shares of Common Stock covered by Options prior to becoming the
holders of record of such shares. All Option grants will permit the exercise
price to be paid in cash or by certified check, bank draft or money order or by
"cashless" exercise. If the Company is sold, reorganized, consolidated, or
merged with another corporation, or if all or substantially all of the assets of
the Company are sold or exchanged (a "Corporate Event"), (i) the Optionee will,
at the time of such Corporate Event, be entitled to receive upon the exercise of
his Option the same number and kind of shares of Common Stock or the same amount
of property, cash
 
                                       38
<PAGE>
or other securities as he would have been entitled to receive upon the
occurrence of such Corporate Event as if he had been, immediately prior to, or
on the record date relating to, such event, the holder of the number of shares
covered by his Option, and (ii) if the Company is not the surviving corporation
in such Corporate Event, the Company will require the successor corporation or
parent thereof to assume such outstanding Options; provided, however, that the
Board may provide that all outstanding Options will terminate as of the
consummation of such Corporate Event and accelerate the exercisability of all
outstanding Options to any date prior to the date of such Corporate Event. In
the event of a "Change of Control" (as defined in the 1998 Stock Option Plan),
each outstanding Option will vest and become immediately exercisable in full as
of the date immediately preceding the date of such Change of Control.
 
    The Board of Directors of the Company may at any time terminate the 1998
Stock Option Plan or from time to time make such modifications or amendments to
the 1998 Stock Option Plan as it may deem advisable, provided that the Board may
not, without the consent of the Optionee, take action which would have a
material adverse effect on outstanding Options or any unexercised rights under
outstanding Options.
 
    The following is a brief discussion of the Federal income tax consequences
of transactions under the 1998 Stock Option Plan based on the Code. The 1998
Stock Option Plan is not qualified under Section 401(a) of the Code.
 
    No taxable income is realized by an Optionee upon the grant or exercise of
an ISO. If Common Stock is issued to an Optionee pursuant to the exercise of an
ISO, and if no disqualifying disposition of such shares is made by such Optionee
within two years after the date of grant or within one year after the transfer
of such shares to such Optionee, then (i) upon sale of such shares, any amount
realized in excess of the Option price will be taxed to such Optionee as a
long-term capital gain and any loss sustained will be a long-term capital loss
and (ii) no deduction will be allowed to the Optionee's employer for Federal
income tax purposes.
 
    If the Common Stock acquired upon the exercise of an ISO is disposed of
prior to the expiration of either holding period described above, generally (i)
the Optionee will realize ordinary income in the year of disposition in an
amount equal to the excess (if any) of the fair market value of such shares at
exercise (or, if less, the amount realized on the disposition of such shares)
over the Option price paid for such shares and (ii) the Company will be entitled
to deduct such amount for Federal income tax purposes if the amount represents
an ordinary and necessary business expense. Any further gain (or loss) realized
by the Optionee will be taxed as short-term or long-term capital gain (or loss),
as the case may be, and will not result in any deduction by the Company.
 
    With respect to NQOs, (i) no income is realized by an Optionee at the time
the Option is granted, (ii) generally, at exercise, ordinary income is realized
by the Optionee in an amount equal to the difference between the Option price
paid for the shares and the fair market value of the shares, if unrestricted, on
the date of exercise, and the Company is generally entitled to a tax deduction
in the same amount subject to applicable tax withholding requirements and (iii)
at sale, appreciation (or depreciation) after the date of exercise is treated as
either short-term or long-term capital gain (or loss) depending on how long the
shares have been held. Deductions for compensation attributable to NQOs (or
disqualified ISOs) granted to the Company's named executive officers may be
subject to the deduction limits of Section 162(m) of the Code, unless such
compensation qualifies as "performance-based" (as defined therein).

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Pursuant to an Exchange Agreement, dated as of June 10, 1998, immediately
prior to the consummation of the Offering, Warburg Pincus, Mr. Slaine and Mr.
Chippari will contribute to the Company all of their direct or indirect equity
interests in the LLC in exchange for an aggregate of 12,200,000 shares of Common
Stock. See "The Exchange." The exact number of shares to be issued to each of
them will be based on the initial public offering price of the Common Stock.
Assuming an initial public offering price of $15.50 per share, Warburg Pincus,
Mr. Slaine and Mr. Chippari will receive 9,682,380, 2,485,497 and 32,123 shares
of Common Stock, respectively.
 
    In connection with the acquisition of CRC Press in January 1997, the Initial
Stockholders loaned an aggregate of $2.5 million to the Company. Such loans were
repaid without interest in April 1997.
 
    The Company transacts business in the amount of approximately $250,000 per
year with a mail house owned by a brother-in-law of Dennis Buda, the President
of CRC Press. The rates charged by such mail house are at or below the rates
charged by other mail houses serving the Company.
 
    The Initial Stockholders are entitled to certain registration rights with
respect to their respective shares of Common Stock. See "Shares Eligible for
Future Sale."
 
    Until such time as the Company uses the net proceeds of the Offering for
acquisitions, the Company intends to invest them in short-term, investment grade
securities. In connection therewith, the Company may utilize the services of an
affiliate of Warburg Pincus, for which the Company will pay reasonable and
customary fees to such affiliate.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    The authorized capital stock of the Company consists of 50,000,000 shares of
Common Stock, par value $.01 per share, and 1,000,000 shares of Preferred Stock,
par value $.01 per share.
 
COMMON STOCK
 
    Prior to the consummation of the Offering, after giving effect to the
Exchange, there will be 12,200,000 shares of Common Stock outstanding, owned of
record by three stockholders. Holders of Common Stock have no pre-emptive,
redemption, conversion or sinking fund rights. Holders of Common Stock are
entitled to one vote per share on all matters submitted to a vote of
stockholders and do not have any cumulative voting rights. In the event of a
liquidation, dissolution, or winding-up of the Company, the holders of Common
Stock are entitled to share equally and ratably in the assets of the Company, if
any, remaining after provision for the payment of creditors and after payment of
any liquidation preference to holders of Preferred Stock. Upon consummation of
the Offering, all outstanding shares of Common Stock will be validly issued,
fully paid and nonassessable. Holders of Common Stock will receive such
dividends, if any, as may be declared by the Board out of funds legally
available for such purposes. See "Dividend Policy."
 
PREFERRED STOCK
 
    The Company is authorized to issue up to 1,000,000 shares of Preferred
Stock. The Board of Directors will have the authority to issue this Preferred
Stock in one or more series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, voting rights, terms of redemption, redemption prices, liquidation
preferences and the number of shares constituting any series or the designation
of such series, without further vote or action by the stockholders. The issuance
of Preferred Stock may have the effect of delaying, deferring or preventing a
change in control of the Company without further action by the stockholders and
may adversely affect the voting and other rights of the holders of Common Stock,
including the loss of voting control to others.
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
    After consummation of the Offering, there will be 33,533,871 shares of
Common Stock and 1,000,000 shares of Preferred Stock available for future
issuance without stockholder approval. These additional shares may be utilized
for a variety of corporate purposes, including future public offerings to raise
additional capital or to facilitate corporate acquisitions. The company
currently does not have any plans to issue additional shares of Common Stock or
Preferred Stock.
 
    One of the effects of the existence of unissued and unreserved Common Stock
and Preferred Stock of the Company may be to enable the Board of Directors to
issue shares to persons supportive of current management which could render more
difficult or discourage an attempt to obtain control of the Company by means of
a merger, tender offer, proxy contest or otherwise, and thereby protect the
continuity of the Company's management and possibly deprive the stockholders of
opportunities to sell their shares of Common Stock at prices higher than
prevailing market prices. Such additional shares also could be used to dilute
the stock ownership of persons seeking to obtain control of the Company pursuant
to the operation of a stockholders' rights plan or otherwise.
 
DELAWARE GENERAL CORPORATION LAW
 
    Pursuant to Section 203 of the DGCL, with certain exceptions, a Delaware
corporation may not engage in any of a broad range of business combinations,
such as mergers, consolidations and sales of assets, with an "interested
stockholder" for a period of three years from the date that such person became
an interested stockholder unless (i) the transaction that results in the
person's becoming an interest stockholder, or the business combination, is
approved by the board of directors of the corporation before
 
                                       42
<PAGE>
the person becomes an interested stockholder, (ii) the interested stockholder
acquires 85% or more of the outstanding voting stock of the corporation in the
same transaction that makes it an interested stockholder or (iii) on or after
the date the person becomes an interested stockholder, the business combination
is approved by the corporation's board of directors and by holders of at least
two-thirds of the corporation's outstanding voting stock, excluding shares owned
by the interested stockholder, at a meeting of the stockholders. Under Section
203, an "interested stockholder" is defined as any person that is (i) the owner
of 15% or more of the outstanding voting stock of the corporation or (ii) an
affiliate or associate of the corporation and the owner of 15% or more of the
outstanding voting stock of the corporation at any time within the three-year
period immediately prior to the date on which it is sought to be determined
whether such person is an interested stockholder or (iii) an affiliate or
associate of such person. Pursuant to an exception within Section 203, no
stockholders of the Company existing prior to the Offering are subject to the
restrictions of Section 203.
 
    Under certain circumstances, Section 203 makes it more difficult for a
person who would be an "interested stockholder" to effect various business
combinations with a corporation for a three-year period, although the
stockholders may elect to exclude a corporation from the restrictions imposed
thereunder. The Company's Certificate of Incorporation does not exclude the
Company from the restrictions imposed under Section 203. The provisions of
Section 203 may encourage companies interested in acquiring the Company to
negotiate in advance with the Board of Directors, since the stockholder approval
requirement would be avoided if a majority of the directors then in office
approve either the business combination or the transaction which results in the
stockholder becoming an interested stockholder. Such provisions also could delay
or frustrate the assumption of control by stockholders, even if such assumption
of control would be beneficial to stockholders, and also could discourage or
make more difficult a merger, tender offer or proxy contest, even if such events
could be beneficial to the interests of stockholders.
 
LIMITATION OF LIABILITY OF DIRECTORS
 
    The Certificate of Incorporation provides that a director of the Company
will not be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability (i) for
any breach of the director's duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) under Section 174 of the
Delaware General Corporation Law, which concerns unlawful payments of dividends,
stock purchases or redemptions, or (iv) for any transaction from which the
director derived an improper personal benefit.
 
    While the Certificate of Incorporation provides directors with protection
from awards for monetary damages for breaches of their duty of care, it does not
eliminate such duty. Accordingly, the Certificate of Incorporation will have no
effect on the availability of equitable remedies such as an injunction or
rescission based on a director's breach of his duty of care. The provisions of
the Certificate of Incorporation described above apply to an officer of the
Company only if he is a director of the Company and is acting in his capacity as
director, and do not apply to officers of the Company who are not directors.
 
REGISTRATION RIGHTS
 
    The Initial Stockholders are entitled to certain registration rights with
respect to their respective shares of Common Stock. See "Shares Eligible for
Future Sale."
 
TRANSFER AGENT
 
    The transfer agent and registrar of the Common Stock is State Street Bank
and Trust Company.
 
                                       43
<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Of the 16,466,129 shares of Common Stock outstanding upon consummation of
the Offering, the 4,250,000 shares of Common Stock sold in the Offering will be
freely transferable without restriction under the Securities Act unless
purchased by "affiliates" of the Company (as that term is used under the
Securities Act and the regulations promulgated thereunder). The remaining
12,216,129 shares of Common Stock outstanding were sold by the Company in
reliance on exemptions from the registration requirements of the Securities Act
and are deemed "restricted" securities within the meaning of Rule 144 under the
Securities Act and may not be resold without registration under the Securities
Act or pursuant to an exemption from registration, including exemptions provided
by Rule 144 under the Securities Act. All such restricted shares are presently
held by affiliates of the Company, are subject to lock-up agreements (as
described under "Underwriting") and will become eligible for sale beginning 180
days after the date of this Prospectus upon expiration of such agreements and
subject to compliance with the Securities Act.
 
    In general, under Rule 144 as currently in effect, any person (or persons
whose shares are aggregated), including an affiliate of the Company, who has
beneficially owned shares for at least a one-year period (as computed under Rule
144) is entitled to sell within any three-month period commencing 90 days after
this Offering such number of shares that does not exceed the greater of (i) 1%
of the then outstanding shares of Common Stock (approximately 164,661 shares
upon consummation of the Offering) and (ii) the average weekly trading volume in
the Common Stock during the four calendar weeks immediately preceding such sale.
Sales under Rule 144 are also subject to certain manner-of-sale provisions,
notice requirements and the availability of current public information about the
Company. A person who is not deemed to have been an affiliate of the company at
any time during the three months preceding a sale, and who has beneficially
owned the shares proposed to be sold for at least two years, is entitled to sell
such shares under Rule 144(k) without regard to the volume limitations or other
requirements described above. The foregoing summary of Rule 144 is not intended
to be a complete description of that rule.
 
   
    Upon consummation of the Offering, 866,638 shares of Common Stock will be
authorized for issuance under the 1998 Stock Option Plan, of which options to
purchase 409,617 shares will be outstanding, assuming an initial public offering
price of $15.50 per share. When issued, such shares may only be resold by
complying with the one-year holding period under Rule 144 or pursuant to
registration under the Securities Act.
    
 
    Prior to the Offering, there has been no public market for securities of the
Company. No predictions can be made of the effect, if any, that the sale or
availability for sale of shares of additional Common Stock will have on the
market price of the Common Stock. Nevertheless, sales of substantial amounts of
Common Stock, or the perception that such sales could occur, could adversely
affect the market price of the Common Stock.
 
    The Company, the Company's directors and executive officers and Warburg
Pincus have agreed, subject to certain exceptions, not to offer, sell or
otherwise dispose of or transfer any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock for a period of
180 days after the date of this Prospectus. See "Underwriting."
 
    Pursuant to a registration rights agreement, the Initial Stockholders have
the right to request two registrations of their shares of Common Stock, provided
that the anticipated aggregate public offering price equals $15 million or more,
and unlimited registrations on Form S-3, provided that the anticipated aggregate
offering price exceeds $5 million. In addition, the Initial Stockholders are
entitled to have their shares included in an unlimited number of registrations
initiated by the Company, subject to certain customary conditions. The rights of
the Initial Stockholders pursuant to the registration rights agreement are
subject to the lock-up agreements described under "Underwriting." In general,
all fees, costs and expenses of such registration (other than underwriting
discounts and selling commissions) will be borne by the Company. The Company has
agreed to indemnify the Initial Stockholders from any liability arising out of
or relating to any untrue statement of a material fact or any omission of a
material fact in any registration statement or prospectus filed by the Company
pursuant to the Registration Rights Agreement, subject to certain exceptions.

In the Purchase Agreement, the several Underwriters have agreed, subject to the
terms and conditions set forth therein, to purchase all of the shares of Common
Stock being sold pursuant to such agreement if any of the shares of Common Stock
being sold pursuant to such agreement are purchased. Under certain
circumstances, under the Purchase Agreement, the commitments of non-defaulting
Underwriters may be increased.
 
    The Representatives have advised the Company that the Underwriters propose
initially to offer the shares of Common Stock to the public at the initial
public offering price set forth on the cover page of this Prospectus, and to
certain dealers at such price less a concession not in excess of $     per share
of Common Stock. The Underwriters may allow, and such dealers may re-allow, a
discount not in excess of $     per share of Common Stock on sales to certain
other dealers. After the Offering, the public offering price, concession and
discount may be changed.
 
    The Company has granted an option to the Underwriters, exercisable for 30
days after the date of this Prospectus, to purchase up to an aggregate of
637,500 additional shares of Common Stock at the initial public offering price
set forth on the cover page of this Prospectus, less the underwriting discount.
The Underwriters may exercise this option solely to cover over-allotments, if
any, made on the sale of the Common Stock offered hereby. To the extent that the
Underwriters exercise this option, each Underwriter will be obligated, subject
to certain conditions, to purchase a number of additional shares of Common Stock
proportionate to such Underwriter's initial amount reflected in the foregoing
table.
 
    At the request of the Company, the Underwriters have reserved for sale, at
the initial public offering price, up to 212,500 of the shares offered hereby to
be sold to certain employees of the Company and certain other persons. The
number of shares of Common Stock available for sale to the general public will
be reduced to the extent such persons purchase such reserved shares. Any
reserved shares which are not orally confirmed for purchase within one day of
the pricing of the Offering will be offered by the Underwriters to the general
public on the same terms as the other shares offered hereby.
 
    The Company, the Company's executive officers and directors and Warburg
Pincus have agreed not to directly or indirectly (i) offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option
or contract to sell, grant any option, right or warrant for the sale of, or
otherwise dispose of or transfer any shares of Common Stock or any securities
convertible into or exchangeable or exercisable for Common Stock, or file any
registration statement under the Securities Act with respect to any of the
foregoing or (ii) enter into any swap or other agreement or any transaction that
transfers, in whole or in part, directly or indirectly, the economic consequence
of ownership of the Common Stock whether any such swap or transaction is to be
settled by delivery of Common Stock or other securities, in cash or otherwise,
without the prior written consent of Merrill Lynch on behalf of the Underwriters
for a period of 180 days after the date of this Prospectus other than (i) the
sale to the Underwriters of the shares of
 
                                       45
<PAGE>
Common Stock in connection with the Offering, (ii) the issuance of options
pursuant to the 1998 Stock Option Plan, (iii) upon the exercise of such options,
(iv) in the Exchange, (v) pursuant to Dennis Buda's employment agreement or (vi)
the issuance of securities as consideration for a merger or acquisition,
provided that the recipients of securities referred to in clauses (v) and (vi)
immediately above agree to be bound by the foregoing restriction. See
"Management--1998 Stock Option Plan" and "Management-- Employment Agreements."
 
    Prior to the Offering, there has been no public market for the Common Stock
of the Company. The initial public offering price has been determined through
negotiations between the Company and the Representatives. The factors considered
in determining the initial public offering price, in addition to prevailing
market conditions, are price-earnings ratios of publicly traded companies that
the Representatives believe to be comparable to the Company, certain financial
information of the Company, the history of, and the prospects for, the Company
and the industry in which it competes, and an assessment of the Company's
management, its past and present operations, the prospects for, and timing of,
future revenues of the Company, the present state of the Company's development,
and the above factors in relation to market values and various valuation
measures of other companies engaged in activities similar to the Company. There
can be no assurance that an active trading market will develop for the Common
Stock or that the Common Stock will trade in the public market subsequent to the
Offering at or above the initial public offering price.
 
    The Common Stock has been approved for listing on the NYSE under the symbol
"IHI," subject to official notice of issuance. In order to meet the requirements
for listing of the Common Stock on the NYSE, the Underwriters have undertaken to
sell lots of 100 or more shares to a minimum of 2,000 beneficial owners.
 
    The Company has agreed to indemnify the Underwriters against certain
liabilities, including certain liabilities under the Securities Act, or to
contribute to payments the Underwriters may be required to make in respect
thereof.
 
    Until the distribution of the Common Stock is completed, rules of the
Commission may limit the ability of the Underwriters and certain selling group
members to bid for and purchase the Common Stock. As an exception to these
rules, the Representatives are permitted to engage in certain transactions that
stabilize the price of the Common Stock. Such transactions consist of bids or
purchases for the purpose of pegging, fixing or maintaining the price of the
Common Stock.
 
    If the Underwriters create a short position in the Common Stock in
connection with the Offering, i.e., if they sell more shares of Common Stock
than are set forth on the cover page of this Prospectus, the Representatives may
reduce that short position by purchasing Common Stock in the open market. The
Representatives may also elect to reduce any short position by exercising all or
part of the over-allotment option described above.
 
    The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the Common Stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group members
who sold those shares as part of the Offering.
 
    In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of the Common Stock to the extent that it
discourages resales of the Common Stock.
 
    Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation
 
                                       46
<PAGE>
that the Representatives will engage in such transactions or that such
transactions, once commenced, will not be discontinued without notice.
 
                                 LEGAL MATTERS
 
    The validity of the Common Stock offered hereby will be passed upon for the
Company by Willkie Farr & Gallagher, New York, New York. Certain legal matters
in connection with this Offering will be passed upon for the Underwriters by
Cahill Gordon & Reindel (a partnership including a professional corporation),
New York, New York.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Members of
 
Information Ventures LLC
 
    We have audited the accompanying consolidated balance sheet of Information
Ventures LLC (the "Company") as of March 31, 1998, and the related consolidated
statements of operations, members' equity and cash flows for the three months
then ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Information
Ventures LLC at March 31, 1998 and the consolidated results of their operations
and their cash flows for the three months then ended in conformity with
generally accepted accounting principles.

1. BUSINESS OPERATIONS
 
    Information Ventures LLC ("IV") was formed on December 2, 1996 to create and
build an information and publishing business. IV functions as a holding company
and, through its subsidiaries (together, the "Company"), publishes information
in print and electronic media in the fields of science, technology, business,
environmental science, intellectual property, and certain related disciplines.
Products are distributed on a worldwide basis and the business has operating
offices in the United States and Europe. Prior to the Company's initial
acquisition, which occurred effective as of January 1, 1997, the Company had no
operations or assets.
 
    In connection with a planned offering of securities, the members will
contribute all of their direct or indirect equity interests to Information
Holdings Inc. ("IH"), a newly formed Delaware corporation, in exchange for
Common Stock of IH, representing 100% of the outstanding equity interest.
Because IH will conduct no business operations prior to the exchange, the
balance sheet and statement of operations for Information Holdings Inc. are not
included herein.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements of the Company include the accounts of
IV and subsidiaries, all which are wholly owned. All material intercompany
accounts and transactions have been eliminated in consolidation. All
acquisitions have been accounted for using the purchase method of accounting and
operating results have been included from the respective dates of acquisition.
 
REVENUE RECOGNITION
 
    Revenues from books and the related cost of sales are recognized when the
product is shipped to the customer. For products sold with the right of return,
revenue is recognized net of a provision for estimated returns. Subscription
payments received are deferred and recognized as revenue in the period in which
the product is shipped.
 
INTERIM FINANCIAL INFORMATION
 
    The financial information for the three months ended March 31, 1997 is
unaudited, but includes all adjustments (consisting only of normal recurring
adjustments) that the Company considers necessary for a fair presentation of the
operating results and cash flows for such period.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of all highly liquid investments with
maturities of three months or less. The cost of these investments is equal to
fair market value.
 
INVENTORIES
 
    Inventories are valued at the lower of cost or market and are determined
under the first-in, first-out method. Inventories at March 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
DIRECT MAIL COSTS
 
    Direct mail costs are expensed upon mailing. Direct mail expense was
$1,444,000 for the period ended March 31, 1998. Direct mail related costs of
$428,000 were included in other current assets at March 31, 1998.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are carried at cost. Expenditures for repairs and
maintenance are expensed as incurred.
 
    Depreciation is calculated on a straight-line basis over the estimated
useful lives of the assets as follows:
 
<TABLE>
<S>                                    <C>
Buildings............................  10 years
Furniture and equipment..............  5 years
Computer equipment...................  3 years
Leasehold improvements...............  Shorter of useful life or lease term
</TABLE>
 
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 amortized over a four year period following
release of the applicable book, using an accelerated amortization method.
Accumulated amortization of pre-publication costs was approximately $2,876,000
at March 31, 1998.
 
PUBLISHING RIGHTS AND OTHER INTANGIBLES
 
    Publishing rights consist primarily of publication agreements, subscriber
lists, trademarks and related assets and are amortized using the straight-line
method over their estimated useful lives ranging from 3-20 years. Amortization
expense of publishing rights in 1998 was approximately $981,000.
 
    Noncompete agreements arising from acquisitions are amortized using the
straight-line basis over the contractual term, currently 3 years. Amortization
expense in 1998 related to noncompete agreements was $8,333.
 
    Goodwill represents acquisition cost in excess of the fair market value of
the net tangible and identifiable intangible assets. Goodwill and related
amortization expense was insignificant in 1998.
 
    The recoverability of publishing rights, other intangibles and other
long-lived assets is assessed periodically and whenever adverse events or
changes in circumstances or business climate indicate that previously
anticipated cash flows warrant a reassessment. When such reassessments indicate
the potential of impairment, all business factors are considered and, if such
assets are not likely to be recovered from future cash flows, they are written
down to recoverable value. The Company, based on current circumstances, does not
believe that any long-lived asset are impaired at March 31, 1998.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES
 
    The Company is a limited liability company ("LLC") and anticipates treatment
as a partnership for federal and most state income taxes. However, the Company
is still liable for income taxes in certain states and thus a provision for
those state income taxes is reflected on the statement of operations.
 
    Deferred income tax assets and liabilities are determined based upon
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse.
 
ACCOUNTING ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reported
period. Actual results could differ from these estimates.
 
CONCENTRATION OF BUSINESS RISK
 
    The Company is not subject to significant credit risk from concentration of
accounts receivable or other assets in any particular customer group, industry
segment or geographic region. A subsidiary of IV has entered into an exclusive
distribution agreement with a third party for sale of its products in regions
outside of North America. Accounts receivable related to this distribution
agreement approximated $630,000 at March 31, 1998.
 
    The Company performs ongoing credit evaluation of its customers and does not
require any collateral for the amounts owed.
 
    The Company maintains its cash in demand deposit accounts which at times may
exceed the Federal Deposit Insurance Corporation ("FDIC") insurance limits. As
of March 31, 1998, the Company had approximately $552,000 of cash in excess of
FDIC insurance limits.

6. DEBT
 
    A subsidiary of the Company maintains a revolving line of credit (the
"Credit Line") borrowing arrangement of $5,000,000 with State Street Bank.
Interest on the Credit Line is due quarterly in arrears at the London Interbank
Offering Rate (LIBOR) plus applicable margin ranging from 1.5% to 2.5%. In 1998,
interest rates under these agreements ranged from 7.22% to 7.38%. At March 31,
1998, the principal amount outstanding is $1,000,000 and the unused bank line of
credit amounted to $4,000,000. The Credit Line expires as follows: June 20,
2000--$1,250,000, June 30, 2001--$1,250,000, and June 30, 2002-- $2,500,000.
There are no compensating balance arrangements. The line is secured by the
tangible and intangible property of the subsidiary. The property securing this
obligation comprises a material portion of the net assets of the Company.
 
    The terms of the Credit Line restrict the subsidiary from incurring
additional debts, repaying debts and declaring dividends and distributions to
affiliates or members over specified amounts. In addition, the Company is
required to maintain certain financial ratios and comply with certain
restrictive covenants. All other future indebtedness of the subsidiary is
subordinate to this Credit Line.
 
    The outstanding balance of $1,000,000 at March 31, 1998 was repaid in full
in April 1998. The Company plans to terminate the Credit Line in 1998.
 
7. MEMBERSHIP INTEREST
 
    The Company has two classes of preferred equity interests which have voting
rights and which share in profits and losses. The Class A Preferred holder
contributed 95% of total capital, is allocated 95% of profits and losses and is
entitled to elect three directors. The Class B Preferred holder contributed 5%
of total capital, is allocated 5% of profits and losses and is entitled to elect
one director. Voting rights are apportioned between the classes on a basis
equivalent to contributed capital.

7. MEMBERSHIP INTEREST (CONTINUED)
    Both classes of such preferred equity interests convert to common equity
interests under certain events, including a public offering of the Company's
securities or the sale of the Company. In the event of a conversion to common
equity interests, the Class A and Class B Preferred holders receive common

    The Company offers two defined contribution savings plan qualifying under
Section 401(k) of the Internal Revenue Code. The plans cover substantially all
full time U.S. employees, both requiring one year of service prior to
eligibility (see below). The Company, via the subsidiaries, matches 50% of such
contributions up to a maximum employee contribution of 6% of salary. The Company
contributed and incurred expenses of $55,000 during 1998 under these plans.
 
    Effective January 1, 1998, one of the plans is being replaced with a new
plan. The new plan will cover all employees of a subsidiary of the Company as of
December 31, 1997 and new employees with more than one year of service (compared
to 90 days service in the prior plan). Other plan provisions are unchanged from
the prior plan.

initial public offering, the Company will become subject to Federal and
additional state income tax. The pro forma provision for income taxes represents
the income tax provisions that would have been reported had the Company been
subject to Federal and additional state income taxes.
 
    The pro forma income tax provision consists of the following (in thousands):

    We have audited the accompanying consolidated balance sheet of Information
Ventures LLC (the "Company") as of December 31, 1997, and the related
consolidated statements of operations, members' equity and cash flows for the

Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Information

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1997
 
1. BUSINESS OPERATIONS
 
    Information Ventures LLC ("IV") was formed on December 2, 1996 to create and
build an information and publishing business. IV functions as a holding company
and, through its subsidiaries (together, the "Company"), publishes information
in print and electronic media in the fields of science, technology, business,
environmental science, intellectual property, and certain related disciplines.
Products are distributed on a worldwide basis and the business has operating
offices in the United States and Europe. Prior to the Company's initial
acquisition (see Note 3), which occurred effective as of January 1, 1997, the
Company had no operations or assets.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements of the Company include the accounts of
IV and subsidiaries, all which are wholly owned. All material intercompany
accounts and transactions have been eliminated in consolidation. All
acquisitions have been accounted for using the purchase method of accounting and
operating results have been included from the respective dates of acquisition.
 
REVENUE RECOGNITION
 
    Revenues from books and the related cost of sales are recognized when the
product is shipped to the customer. For products sold with the right of return,
revenue is recognized net of a provision for estimated returns. Subscription
payments received are deferred and recognized as revenue in the period in which
the product is shipped.
 
DEFERRED REVENUE
 
    In connection with the acquisition of companies, it is the Company's policy
to record deferred revenue as the cost to fulfill rather than based on the
subscription payments received.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of all highly liquid investments with
maturities of three months or less. The cost of these investments is equal to
fair market value.
 
INVENTORIES
 
    Inventories are valued at the lower of cost or market and are determined
under the first-in, first-out method. Inventories at December 31, 1997 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.
 
DIRECT MAIL COSTS
 
    Direct mail costs are expensed upon mailing. Direct mail expense was
$6,119,000 for the period ended December 31, 1997. $418,000 of direct mail
related costs were included in other current assets at December 31, 1997.

                               DECEMBER 31, 1997
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
PROPERTY AND EQUIPMENT
 
    Property and equipment are carried at cost. Expenditures for repairs and
maintenance are expensed as incurred.
 
    Depreciation is calculated on a straight-line basis over the estimated
useful lives of the assets as follows:
 
<TABLE>
<S>                                    <C>
Buildings............................  10 years
Furniture and equipment..............  5 to 7 years
Computer equipment...................  3 years
Leasehold improvements...............  Lesser of useful life or lease term
</TABLE>
 
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 amortized over a four year period following
release of the applicable book, using an accelerated amortization method.
Accumulated amortization of pre-publication costs was approximately $2,313,000
at December 31, 1997.
 
PUBLISHING RIGHTS AND OTHER INTANGIBLES
 
    Publishing rights consist primarily of publication agreements, subscriber
lists, trademarks and related assets and are amortized using the straight-line
method over their estimated useful lives ranging from 3-20 years. Amortization
of publishing rights in 1997 was approximately $3,000,000.
 
    Noncompete agreements arising from acquisitions are amortized using the
straight-line basis over the contractual term, currently 3 years. Amortization
in 1997 related to noncompete agreements was $19,000.
 
    Goodwill represents acquisition cost in excess of the fair market value of
the net tangible and identifiable intangible assets. Goodwill and related
amortization were insignificant in 1997.
 
    The recoverability of publishing rights, other intangibles and other
long-lived assets is assessed periodically and whenever adverse events or
changes in circumstances or business climate indicate that previously
anticipated cash flows warrant a reassessment. When such reassessments indicate
the potential of impairment, all business factors are considered and, if such
assets are not likely to be recovered from future cash flows, they are written
down to recoverable value. The Company, based on current circumstances, does not
believe that any long-lived assets are impaired at December 31, 1997.
 
INCOME TAXES
 
    The Company is a limited liability company ("LLC") and anticipates treatment
as a partnership for federal and most state income taxes. However, the Company
is still liable for income taxes in certain states and thus a provision for
those state income taxes is reflected on the statement of operations.
 
    Deferred income tax assets and liabilities are determined based upon
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
ACCOUNTING ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reported
period. Actual results could differ from these estimates.
 
CONCENTRATION OF BUSINESS RISK
 
    The Company is not subject to significant credit risk from concentration of
accounts receivable or other assets in any particular customer group, industry
segment or geographic region. A subsidiary of IV has entered into an exclusive
distribution agreement with a third party for sale of its products in regions
outside of North America. Accounts receivable related to this distribution
agreement approximated $1.4 million at December 31, 1997.
 
    The Company performs ongoing credit evaluation of its customers and does not
require any collateral for the amounts owed.
 
    The Company maintains its cash in demand deposit accounts which at times may
exceed the FDIC insurance limits. As of December 31, 1997, the company had
approximately $355,000 of cash in excess of FDIC insurance limits.

RECENT ACCOUNTING PRONOUNCEMENTS
 
    In 1997, the FASB issued SFAS No. 129, DISCLOSURE OF INFORMATION ABOUT
CAPITAL STRUCTURE, and SFAS No. 130, REPORTING COMPREHENSIVE INCOME. SFAS No.
129 contains no change in the Company's disclosure requirements, and SFAS No.
130 has no impact on the Company's financial position or results of operations.
 
    In June 1997, the FASB issued SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN
ENTERPRISE AND RELATED INFORMATION. The Company anticipates that the adoption of
this statement will not have any significant impact on the Company's financial
statements.

Company has revalued the deferred subscription revenues based on cost to
fulfill. As a result, the deferred subscription revenues were reduced by $4
million. Had the Company not made such revaluation, revenues and gross profit
for the year ended December 31, 1997 would have been higher by $4 million.

8. DEBT
 
    A subsidiary of the Company maintains a revolving line of credit (the
"Credit Line") borrowing arrangement of $5,000,000 with State Street Bank.
Interest on the Credit Line is due quarterly in arrears at the London Interbank
Offering Rate (LIBOR) plus applicable margin ranging from 1.5% to 2.5%. In 1997,
interest rates under these agreements ranged from 7.22% to 7.38%. At December
31, 1997, the principal amount outstanding is $2,000,000 and the unused bank
line of credit amounted to $3,000,000. No amount is currently due. The Credit
Line expires as follows: June 20, 2000--$1,250,000, June 30, 2001--$1,250,000,
and June 30, 2002--$2,500,000. There are no compensating balance arrangements.
The line is secured by the tangible and intangible property of the subsidiary.
The property securing this obligation comprises a material portion of the net
assets of the Company.
 
    The terms of the Credit Line restrict the subsidiary from incurring
additional debts, repaying of debts, declaring of dividends and distributions to
affiliates or members over specified amounts. In addition, the Company is
required to maintain certain financial ratios and comply with certain
restrictive covenants. All other future indebtedness of the subsidiary is
subordinate to this Credit Line. At December 31, 1997, the subsidiary was in
compliance with all positive and negative covenants contained in the line of
credit agreement.
 
9. MEMBERSHIP INTEREST
 
    The Company has two classes of preferred equity interests which have voting
rights and which share in profits and losses. The Class A Preferred holder
contributed 95% of total capital, is allocated 95% of profits and losses and is
entitled to elect three directors. The Class B Preferred holder contributed 5%
of total capital, is allocated 5% of profits and losses and is entitled to elect
one director. Voting rights are apportioned between the classes on a basis
equivalent to contributed capital.

9. MEMBERSHIP INTEREST (CONTINUED)
    Both classes of such preferred equity interests convert to common equity
interests under certain events, including a public offering of the Company's
securities or the sale of the Company. In the event of a conversion to common
equity interests, the Class A and Class B Preferred holders receive common
equity interests under a predetermined formula.
 
10. EMPLOYEE BENEFIT PLANS
 
    The Company offers two defined contribution savings plans qualifying under
Section 401(k) of the Internal Revenue Code. The plans cover substantially all
full time U.S. employees; one plan requiring 90 days of service prior to
eligibility and the other requiring one year of service prior to eligibility.
The Company, via the subsidiaries, matches 50% of such contributions up to a
maximum employee contribution of 6% of salary. The Company contributed and
incurred expenses of $86,000 during 1997 under these plans.
 
    Effective January 1, 1998, one of the plans is being replaced with a new
plan. The new plan will cover all employees of a subsidiary of the Company as of
December 31, 1997 and new employees with more than one year of service (compared
to 90 days service in the prior plan). Other plan provisions are unchanged from
the prior plan.

    In January 1998, a subsidiary of the Company acquired certain assets of the

13. PRO FORMA INCOME TAXES (UNAUDITED)
 
    As discussed in Note 2, the Company is a limited liability company that
anticipates treatment as a partnership for federal and certain state income
taxes. In connection with the offering made hereby, the Company will become
subject to Federal and additional state income tax. The pro forma provision for

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
The Board of Directors and Shareholder
 
CRC Press, Inc.
 
    We have audited the accompanying consolidated balance sheets of CRC Press,
Inc. (a wholly-owned subsidiary of The Times Mirror Company) as of December 31,
1995 and 1996, and the related consolidated statements of operations,
shareholder's equity, and cash flows for the years then ended. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of the CRC
Press, Inc. at December 31, 1995 and 1996 and the results of its operations and
its cash flows for the years then ended, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1995 AND 1996
 
1. BUSINESS OPERATIONS
 
    CRC (as defined below) publishes reference books and other information for
scientists and engineers in industry, government and academia. Revenues
typically increase in the third and fourth quarters more as a result of its
publication schedule than from any seasonality aspects of its customers.
 
    CRC routinely assesses the financial strength of significant customers and
this assessment, combined with the large number and geographic diversity of its
customer base, limits its concentration of risk with respect to trade
receivables.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
    As of December 31, 1995, the consolidated financial statements include the
accounts of CRC Press, Inc. and its wholly-owned subsidiary, Environmental
Education Enterprises (collectively "CRC" ). On March 20, 1996, Environmental
Education Enterprises was sold to an unrelated party. CRC is a wholly-owned
subsidiary of The Times Mirror Company ("Times Mirror"). All significant
intercompany accounts and transactions have been eliminated in consolidation.
 
    The historical consolidated financial statements do not necessarily reflect
the results of operations or financial position that would have existed had CRC
been an independent company. Times Mirror provides certain legal services, tax
compliance and planning reviews, risk management and various other corporate
services to CRC. The cost of these services is not believed to be material and
is not included in the financial statements of CRC.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of all highly liquid investments with
maturities of three months or less. The cost of these investments is equal to
fair market value.
 
INVENTORIES
 
    Inventories are carried at the lower of cost or market and are determined
under the first-in, first-out method. Inventories consist of books and other
finished products. There were no raw materials or work-in-progress as of
December 31, 1995 and 1996.
 
BUILDING, EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
    The building is carried at the net present value of the capital lease
obligation. Leasehold improvements and equipment are carried on the basis of
cost. Maintenance and repairs are charged to expense as incurred. Additions,
improvements and replacements are capitalized.
 
    Depreciation is calculated on a straight-line basis over the estimated
useful lives as follows:
 
<TABLE>
<S>                                    <C>
Building.............................  Lease term - 20 years
Furniture and equipment..............  5 to 7 years
Leasehold improvements...............  Lesser of useful life or lease term

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
GOODWILL AND OTHER INTANGIBLE ASSETS
 
    Goodwill recognized in business combinations is amortized on a straight-line
basis over 40 years. Accumulated amortization was $4,745,000 and $17,367,000 at
December 31, 1995 and 1996, respectively. Amortization expense amounted to
$686,000 for 1995 and $629,000 for 1996. The cost of covenants-not-to-compete is
amortized on a straight-line basis over 2 to 5 years. Accumulated amortization
was $821,000 and $1,357,000 at December 31, 1995 and 1996, respectively.
Amortization expense amounted to $536,000 for 1995 and 1996.
 
    CRC assesses on an ongoing basis the recoverability of goodwill and other
intangibles based on estimates of future undiscounted cash flows compared to net
book value. If the future undiscounted cash flows estimate was less than net
book value, net book value would then be reduced to fair value based on an
estimate of discounted cash flow. CRC also evaluates the amortization periods of
assets, including goodwill and other intangibles, to determine whether events or
circumstances warrant revised estimates of useful lives.
 
    Based on the January 10, 1997 sale of CRC's net assets (see Note 11), CRC
determined that goodwill had been impaired and recorded an impairment charge of
approximately $10,666,000, which is net of approximately $1,300,000 representing
the recovery of certain restructuring liabilities that were accrued as of
December 31, 1995.
 
DIRECT MAIL COSTS
 
    Direct mail costs are expensed upon mailing. Direct mail expense was
approximately $3,646,000 and $3,596,000 for the years ended December 31, 1995
and 1996, respectively. Other current assets as of December 31, 1995 and 1996
included approximately $307,000 and $19,000, respectively.
 
PRE-PUBLICATION COSTS
 
    Certain expenses for books, primarily design and order pre-production costs,
are deferred and charged to expense over the estimated product life. These costs
are amortized over a 4 year period following the release of the applicable book,
using an accelerated amortization method. Accumulated amortization of
pre-publication costs was $7,587,000 and $10,086,000 at December 31, 1995 and
1996, respectively.
 
REVENUE RECOGNITION
 
    Revenues from books sold with the right of return are recognized net of a
provision for estimated returns. Revenues from newsletter subscriptions are
deferred as unearned income at the time of the sale. A pro rata share of the
subscription price is included in revenue as the newsletter is delivered,
generally over one year.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
USE OF ESTIMATES AND OTHER UNCERTAINTIES
 
    Financial statements prepared in accordance with generally accepted
accounting principles require management to make estimates and judgments that
affect amounts and disclosures reported in the financial statements. Actual
results could differ from those estimates although management does not believe
that any differences would materially affect its financial position or reported
results. CRC's future results could be adversely affected by a general economic
downturn resulting in decreased professional or corporate spending on
discretionary items such as information products.
 
3. RESTRUCTURING PROGRAM
 
    During 1995, the Company recorded restructuring charges of $10,727,000,
consisting primarily of asset writeoffs, in connection with a comprehensive and
systematic review of its operations, cost structure, and balance sheet.
Additional charges of $1,032,000 were also included in 1995 results. These
charges do not meet the accounting criteria for inclusion in restructuring
charges, but were part of CRC's restructuring program.
 
    Liabilities of $1,699,000 representing cash to be paid for restructuring
program actions, are included in the consolidated balance sheets at December 31,
1995.
 
4. OTHER INFORMATION
 
    CRC participates in Time Mirror's cash management system, where the bank
sends daily notification of checks presented for payment. Times Mirror transfers
funds from other sources to cover the checks presented for payment. This program
generally results in a book overdraft as a result of checks outstanding. The
book overdraft of $514,000 and $588,000 on December 31, 1995 and 1996,
respectively, has been reclassified to accounts payable.
 
    CRC is largely self-insured for workers compensation group health benefits
and certain other loss contingencies.

7. INCOME TAXES
 
    CRC is included in Times Mirror's consolidated Federal income tax return.
CRC files separate tax returns in Florida, Missouri and Washington, D.C. Under a
tax sharing arrangement with Times Mirror, CRC's deferred tax assets are
recoverable against the future taxable earnings of CRC or Times Mirror.
 
    CRC accounts for income taxes under FASB Statement No. 109 "Accounting for
Income Taxes" (FASB 109). Deferred income tax assets and liabilities are
determined based upon differences between financial reporting and tax bases of
assets and liabilities and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse.
 
    Income tax (benefit) expense for 1995 and 1996, which is computed as if CRC
filed a separate income tax return, consisted of the following (in thousands):

    FASB 109 requires a valuation allowance to reduce the deferred tax assets
reported if, based on the weight of evidence, it is more likely than not that
some portion or all of the deferred tax assets will not be realized. Due to
CRC's tax sharing arrangements with Times Mirror, management has determined that
a valuation allowance is not required at December 31, 1995 and 1996.
 
8. RETIREMENT PLANS AND POSTRETIREMENT BENEFITS
 
    CRC provides defined pension benefits to employees based on years of service

8. RETIREMENT PLANS AND POSTRETIREMENT BENEFITS (CONTINUED)
benefits are provided under The Times Mirror Pension Plan (the "Times Mirror
Plan"). The Times Mirror Plan is generally funded on a current basis in
accordance with the Employee Retirement Income Security Act of 1974.
 
    Substantially all employees over age 21 with one year of service are
eligible to participate in the Times Mirror's Savings Plus Plan (the "Savings
Plus Plan"). Eligible employees may contribute from 1 percent to 13 percent of
their basic compensation. CRC makes matching contributions equal to 50 percent
of employee before-tax contributions from 1 percent to 6 percent. Employees may
choose among five investment options, including a Times Mirror common stock
fund, for investing their contributions and CRC's matching contribution.
 
    Retirement plan expense for 1995 and 1996 consisted of defined contribution
plan expense for the Saving Plus Plan of $114,000 and $119,000, respectively and

</TABLE>
 
    The assumed health care cost trend rate can significantly affect
postretirement expense and liabilities. An increase of 1 percent in the health
care cost trend rate would increase 1995 and 1996 net periodic postretirement
expense by $8,000 and $7,000, respectively and increase the accumulated
postretirement benefit obligations as of December 31, 1995 and 1996 by $16,000
and $33,000, respectively.
 
    On January 10, 1997, CRC was sold by Times Mirror (see Note 11). In
accordance with the Asset Purchase Agreement, the Retirement Plans and
Postretirement Benefits Liabilities were not assumed by the purchaser and were
retained by Times Mirror.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Partners of
 
MicroPatent
 
    We have audited the accompanying balance sheets of MicroPatent (the
"Company") as of June 30, 1996 and 1997, and the related statements of income
and partners' deficit and cash flows for the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of MicroPatent at June 30, 1996
and 1997 and the results of its operations and its cash flows for the years then
ended in conformity with generally accepted accounting principles.

                                 JUNE 30, 1997
 
1. BUSINESS OPERATIONS AND BASIS OF PRESENTATION
 
    MicroPatent (the "Company") is a general partnership founded in 1989 that
publishes intellectual property databases for the patent and trademark markets,
all in electronic format. Its databases, which are provided on the Internet,
Intranet and on CD-ROM, are used by legal and research professionals and
corporations.
 
    On January 1, 1997, the Neato division of the Company was transferred to
certain partners of the Company for net book value.
 
    On July 2, 1997, net assets of the Company (which excluded the Neato assets)
were purchased by MicroPatent LLC, a newly-formed subsidiary of Information
Ventures LLC for $7,400,000. Accordingly, these financial statements have been
prepared representing the operations acquired by the subsidiary of Information
Ventures LLC.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
    Revenues include the sale of patent and trademark information on CD-ROM and
the Internet. Subscription sales and related cost of sales are recognized
ratably over the life of the subscription as the information is made available
or shipped to the customer. Subscription payments received are deferred and
recorded as revenue in the period in which the information is made available.
Nonsubscription sales and related cost of sales are recognized when information
is made available or shipped to the customer.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of all highly liquid investments with
maturities of three months or less, when purchased. The cost of these cash
equivalents is equal to fair market value.
 
INVENTORIES
 
    Inventories are valued at lower of cost or market and are determined under
the first-in, first-out method. Inventories at June 30, 1996 and 1997 consist of
finished products and raw materials. There was no significant work-in-process as
of June 30, 1996 and 1997.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Expenditures for repairs and
maintenance are expensed as incurred.
 
    The Company provides for depreciation and amortization primarily using the
straight-line method over the estimated useful lives of the various assets as
follows:

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
CAPITALIZED DATABASE COSTS
 
    Capitalized database costs consist of masters, data and software purchased.
Amortization is computed by an accelerated method over a period of five years.
 
INCOME TAXES
 
    The Company is organized as a partnership and accordingly all income and
expenses are passed through to the Partners. Therefore, the Company's financial
statements exclude a provision for income taxes.
 
ADVERTISING EXPENSE
 
    Advertising costs are expensed as incurred and approximated $128,968 and
$201,249 as of June 30, 1996 and 1997, respectively.
 
ACCOUNTING ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANT
 
To the Board of Directors of
St. Lucie Press Corporation, Inc.,
 
I have audited the accompanying balance sheet of St. Lucie Press Corporation,
Inc., (the "Company") as of December 31, 1996, and the related statements of
income, retained earnings and cash flows for the year ended December 31, 1996.
These financial statements are the responsibility of the Company's management.
My responsibility is to express an opinion on these financial statements based
on my audit.
 
I conducted my audit in accordance with generally accepted auditing standards.
Those standards require that I plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
I believe that my audit provides a reasonable basis for my opinion.
 
In my opinion, the financial statements referred to above present fairly, in all
material respects, the financial position of St. Lucie Press Corporation, Inc.,
as of December 31, 1996, and the results of its operations ands its cash flows
for the year then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    St. Lucie Press Corporation, Inc. (the "Company"), is a publisher of printed
and electronic media for the global education, scientific and professional
markets. Its products consist of books, videos and newsletters which are sold
both domestically and internationally.
 
    The significant accounting policies followed by the Company are summarized
below:
 
ACCOUNTING ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenues and expenses during the reporting
period. Actual results could differ from those estimates.
 
ACQUISITIONS
 
    On August 1, 1995 the Company purchased certain operating assets and assumed
certain operating debts of Goose Run Press, Inc., d.b.a. GR Press in exchange
for ten percent of the outstanding shares of the Company. An excess purchase
price of approximately $56,000 has been determined, based upon the fair values
of assets acquired and liabilities assumed.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents include cash on hand, demand deposits and highly
liquid investments. The Company considers all highly liquid investments
purchased with an original maturity date of three months or less to be cash
equivalents.
 
REVENUE RECOGNITION
 
    Sales primarily consist of the publication of books and videos for which
sales and the related cost of sales are recognized when the book or video is
shipped to the customer. Revenues from books sold with the right of return are
recognized net of a provision for estimated return. Subscription payments
received are deferred and reported as income in the period in which the related
issue is shipped.
 
INVENTORIES
 
    Inventories are stated at the lower of cost or market. Cost is principally
determined by first-in, first-out method. Inventories at December 31, 1996
consist of books and other finished products. There were no raw materials or
work-in-process as of December 31, 1996. Consideration is given to obsolescence
and other factors in evaluating the net realizable value.
 
LONG-LIVED ASSETS
 
    The Company accounts for long-lived assets pursuant to Statement of
Financial Standards (SFAS) No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED
ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF, which requires impairment
losses to be recorded in long-lived assets used in operations when events or
changes in circumstances indicates that the carrying amount of an asset may not
be recoverable. Management reviews long-lived assets and the related intangible
assets for impairment whenever events or changes in

circumstances indicate the assets may be impaired. The Company, based on current
circumstances, does not believe that any long-lived assets are impaired at
December 31, 1996.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Improvements and replacements are
capitalized, while expenditures for maintenance and repairs are charged to
expense as incurred.
 
    Depreciation is computed using the straight-line method over the estimated
useful lives of the assets. Accelerated depreciation methods are used for tax
purposes. The cost and accumulated depreciation of property sold or retired are
removed from the accounts and gains or losses, if any, are reflected in the
earnings for the period.
 
INTANGIBLE ASSETS
 
    Intangible assets consist primarily of publication rights and trademarks
arising from acquisitions and goodwill. These assets are recorded at cost and
amortized using the straight-line method over their estimated useful lives
ranging from 7 to 20 years. The Company continually reviews the recoverability
of the carrying value of these assets using various factors, including the
methodology prescribed in SFAS No. 121.
 
ADVERTISING COSTS
 
    Pursuant to Statement of Position (SOP) 93-7, REPORTING ON ADVERTISING
COSTS, the production costs of advertising are expensed in the period in which
the costs are incurred. Advertising expense was approximately $897,404 for the
year ended December 31, 1996. At December 31, 1996, approximately $62,112 of
advertising related costs were included in other current assets.
 
DEFERRED PRODUCT DEVELOPMENT COSTS
 
    Certain expenses for books, primarily design and other pre-production costs,
are capitalized and charged to expense over the estimated product life as the
products are sold, which is typically three years.
 
INCOME TAXES
 
    The Company has elected to be treated as a "S" Corporation for federal and
state income tax purposes.
 
    Deferred income taxes are determined utilizing a liability method. This
method gives consideration to the future tax consequences associated with
differences between financial accounting and tax bases of assets and
liabilities. These differences relate to items such as depreciable properties.
This method gives immediate effect to changes in income tax laws upon enactment.
The income statement effect is derived from changes in deferred income taxes on
the balance sheet.
 
CONCENTRATION OF BUSINESS RISK
 
    The Company is not subject to significant credit risk from concentration of
accounts receivable or other assets in any particular customer group, industry
segment or geographical region. The Company performs ongoing credit evaluation
of its customers and does not require any collateral for the amounts owed. The
customary payment term for most customers is 30 days. Occasionally, the Company
grants

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the DGCL empowers a Delaware corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of such corporation) by reason of the fact that such person is or was a
director, officer, employee or agent of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. A corporation may indemnify such person
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding if he acted in good faith and in a manner
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, has no
reasonable cause to believe his conduct was unlawful. A corporation may, in
advance of the final disposition of any civil, criminal, administrative or
investigative action, suit or proceeding, pay the expenses (including attorneys'
fees) incurred by any officer or director in defending such action, provided
that the director or officer undertake to repay such amount if it shall
ultimately be determined that he is not entitled to be indemnified by the
corporation.
 
    A Delaware corporation may indemnify officers and directors in an action by
or in the right of the corporation to procure a judgment in its favor under the
same conditions, except that no indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, the corporation must indemnify him
against the expenses (including attorneys' fees) which he actually or reasonably
incurred in connection therewith. The indemnification provided is not deemed to
be exclusive of any other rights to which an officer or director may be entitled
under any corporation's bylaw, agreement, vote or otherwise.
 
    The Company has adopted provisions in its Certificate of Incorporation and
Bylaws that provide that the Company shall indemnify its officers and directors
to the maximum extent permitted under the Act.
 
                                      II-1

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS (CONTINUED)
    In addition, the Purchase Agreement filed as Exhibit 1.1 to the Registration
Statement provides for indemnification of the Company, its officers and its
directors by the Underwriters under certain circumstances.
 
    The Company's officers and directors are also covered under the Company's
directors' and officers' insurance policy.

ITEM 17. UNDERTAKINGS
 
    (1) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Purchase Agreement certificates for
the Common Stock in such denominations and registered in such names as required
by the Underwriters to permit prompt delivery to each purchaser.
 
    (2) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to its Bylaws, the Purchase Agreement or otherwise, the
Registrant has been advised that, in the opinion of the Commission, such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling

ITEM 17. UNDERTAKINGS (CONTINUED)
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
    (3) The Registrant hereby undertakes that:
 
       (a) For purposes of determining any liability under the Securities Act,
       the information omitted from the form of prospectus filed as part of this
       Registration Statement in reliance upon Rule 430A and contained in a form
       of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
       or 497(h) under the Securities Act shall be deemed to be part of the
       Registration Statement as of the time it was declared effective.
 
       (b) For the purpose of determining any liability under the Securities
       Act, each post-effective amendment that contains a form of prospectus
       shall be deemed to be a new registration statement relating to the
       securities offered therein, and the offering of such securities at that
       time shall be deemed to be the initial bona fide offering thereof.

undersigned, thereunto duly authorized, in New York, New York on August 4, 1998.
