                                  THE COMPANY
 
  The Company believes it is the world's preeminent integrated media and
marketing company focused on computing and Internet-related technology, with
principal platforms in print publishing, trade shows and conferences, online
content, market research and education. The Company provides global technology
companies with marketing strategies for reaching key decision-makers.
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the top
three computer magazines in the U.S. and are among the top 25 U.S. magazines,
each as measured by total revenue in 1996 (the latest year for which data is
available). The Company also produces the world's most important trade shows
serving vendors, resellers, buyers and users of computer technology, including
COMDEX/Fall, the largest trade show in the U.S. The Company's ZDNet.com Web
site ("ZDNet") is the leading computing content site and ranked the number one
Web site in 1997 in the category of news, information and entertainment, as
measured by visitors per month.
 
  The Company's 28 primary U.S. and international titles, including its joint
ventures, and over 50 licensed publications, total more than 80 publications
distributed worldwide, with a combined circulation of over eight million
primary readers. In 1997, Ziff-Davis was the largest technology publisher in
the U.S. in terms of total magazine revenue. In that same year, Ziff-Davis
accounted for 36.8% of all advertising and circulation dollars spent in
computer periodicals, with at least 50% more total magazine revenue than its
closest competitor. The preeminence of the Company's publications among readers
and advertisers is based on its comprehensive market and product coverage, the
quality of its editorial content and the influence of its readership.
 
  In 1997, the Company produced over 50 trade shows and conferences worldwide
with over two million estimated attendees. The Company's COMDEX/Fall event is
the number one ranked trade show for all industries in the U.S. as measured by
total revenue, total exhibit space and number of attendees.
 
  The Company's other media and marketing platforms include online content,
market research, education and the publication of computer-related newsletters
and training manuals and materials. In addition, the Company has an option to
acquire an interest in ZDTV: Your Computer Channel ("ZDTV"), the first 24-hour
cable television channel and integrated Web site focused exclusively on
computers, technology and the Internet, which is expected to be launched in the
first half of 1998.
 
                                       5
<PAGE>
 
 
  The Company had total revenue of $1.154 billion for 1997. The Company's
revenue is primarily derived from advertising sales, which represented 51.9% of
total revenue in 1997. The second largest component of the Company's revenue is
derived from trade shows and conferences, which accounted for 23.5% of total
revenue in 1997. Circulation revenue, comprised of subscription and newsstand
single copy sales, generated 13.1% of the Company's revenue in 1997 and other
revenue components, including online content, market research and revenue
derived from joint ventures and licenses, contributed 11.5% in 1997. The
Company had a net loss of $71.2 million for 1997 and will report a loss from
operations of $24 million for the first quarter of 1998 as compared with a loss
from operations of $15.6 million for the first quarter of 1997. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
BUSINESS AND OPERATING STRATEGY
 
  The Company's objective is to be the preferred marketing partner to
technology vendors and service providers seeking to reach primary decision-
makers involved in the specification and purchase of their products and
services. Major elements of the Company's strategy include:
 
  .Maintain Focus on the Computer and Internet Technology Markets
 
  .Develop the Most Comprehensive, Objective and Authoritative Content
 
  .Build Upon Brand Strength of Existing Media Properties
 
  .Continue to Leverage Multiple Media Marketing Platforms
 
  .Expand Leadership on the Internet
 
  .Launch New Products and Services
 
  .Expand Global Reach
 
  Although none of the proceeds of the Offerings will be paid to the Company,
the Company expects to fund its business and operating strategy from internally
generated cash flow from operations, which are estimated to be sufficient to
fund investments and the repayment of indebtedness. As a result of certain
large non-cash charges, the Company's earnings for the year ended December 31,
1997 were insufficient to cover fixed charges by $74.5 million and, on a pro
forma basis, by $8.8 million. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
RELATIONSHIP WITH SOFTBANK
 
  Upon the completion of the Reorganization described below, SOFTBANK Corp., a
Japanese corporation publicly-traded on the Tokyo Stock Exchange First Section
(together with its affiliates, "Softbank"), will own approximately 74.2% of the
outstanding shares of Common Stock (71.4% if the overallotment option relating
to the Common Stock Offering is exercised in full). The Company and Softbank
have entered into certain agreements governing various interim and ongoing
relationships between the two companies. Softbank also has given the Company an
undertaking not to expand certain operations outside Japan in competition with
the Company without the prior approval of the Company's management directors
after consulting with the Company's independent directors. This undertaking
would not preclude investments by investment funds managed by Softbank. The
Company has undertaken not to compete with Softbank in Japan without the prior
approval of SOFTBANK Corp.'s Board of Directors and has agreed to afford
Softbank the continuing right to license all of the Company's products and
services in Japan.  See "Risk Factors--Control by Principal Stockholders and
Potential Conflicts of Interest," "The Company--Relationship with Softbank" and
"Certain Transactions."

                               THE REORGANIZATION
 
  The Company is an indirect subsidiary of SOFTBANK Corp., which, as of
December 31, 1997, was 50.2% owned by Mr. Masayoshi Son, its President,
including 43.4% directly held by his 99% owned holding company, MAC Inc., a
Japanese corporation ("MAC"), and SOFTBANK Corp.'s largest shareholder. Prior
to the Offerings, the Company's businesses were conducted through various
indirect subsidiaries of SOFTBANK Corp. The Company's publishing business was
principally conducted through Ziff-Davis Inc. ("ZDI") and its trade show
business was principally conducted through ZD COMDEX and Forums Inc. ("ZDCF").
The MAC Assets were managed by ZDI and ZDCF, but were owned by MAC.
Concurrently with the Offerings, the Company will consummate a Reorganization
(as described under "The Reorganization") pursuant to which: (i) all of the
stock of ZDI and ZDCF will be contributed to the Company by Softbank in
exchange for 74.2% of the Company's Common Stock; (ii) the Company will
complete the purchase of the MAC Assets; (iii) the Company will issue and sell
the Common Stock and the Notes pursuant to the Offerings; (iv) the Company will
enter into a credit facility with a group of financial institutions (the
"Credit Facility") and borrow $1.25 billion thereunder; and (v) approximately
$929 million of the Company's obligations to Softbank will be converted to
equity and the Company will repay approximately $1.587 billion of obligations
to Softbank. The Company has obtained a commitment letter from The Bank of New
York, Morgan Stanley Senior Funding, DLJ Capital Funding and The Chase
Manhattan Bank to provide such Credit Facility. All of the transactions
comprising the Reorganization will be deemed to occur simultaneously. See "Risk
Factors--Risks Relating to the Reorganization" and "--Absence of History as a
Stand-Alone Company; Limited Relevance of Historical Financial Information,"
"The Reorganization" and "Unaudited Pro Forma Combined Financial Information."
 
  After giving pro forma effect to the Reorganization, as of December 31, 1997
the Company would have had outstanding approximately $1.59 billion of
Indebtedness, including a $450 million term loan, a $400 million term loan,
$400 million drawn under a $500 million revolving credit loan under the Credit
Facility, approximately $94 million of Indebtedness owed to Softbank and the
Notes. All of such Indebtedness (other than the Notes) would have been Senior
Indebtedness. As of such date, the Company's subsidiaries would have had
approximately $497.4 million of liabilities (excluding Indebtedness owed to the
Company). The Company believes that, based on its current level of operations
and anticipated growth, the Company's ability to generate cash, together with
other available sources of funds (including available cash on hand at December
31, 1997, of $30.3 million) will be adequate over the next 12 months to make
required payments of principal and interest on the Company's indebtedness, to
fund anticipated capital expenditures and future working capital requirements.
The Company expects to fund its business and operating strategy from internally
generated cash flow from operations, which are estimated to be sufficient to
fund investments as well as the repayment of indebtedness. In addition, after
giving effect to the Reorganization the Company will have $100 million of
undrawn and available credit under its revolving credit facility. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

                             November 1, 1998.
 
Optional Redemption......... The Notes may be redeemed at the option of the
                             Company, in whole or in part, at any time on or

                             forth herein, plus accrued and unpaid interest,
                             if any, to the date of redemption. In addition,
                             upon one or more Public Equity Offerings
                             consummated prior to May 1, 2001 the Company may
                             at its option redeem up to 35% of the original
                             principal amount of the Notes from the proceeds
                             thereof at 108.5% of the principal amount thereof
                             plus accrued interest to the date of redemption,

                             outstanding after such redemption. See
                             "Description of Notes--Optional Redemption."
 
Change of Control........... Upon a Change of Control, each holder of Notes
                             will have the right to require the Company to
                             purchase such holder's Notes at a price of 101%
                             of the principal amount thereof plus accrued
                             interest, if any, to the date of purchase. There
                             can be no assurance that the Company will have
                             the financial resources necessary to purchase the
                             Notes upon a Change of Control. See "Risk
                             Factors--Possible Inability to Repurchase Notes
                             upon Change of Control" and "Description of
                             Notes--Repurchase of Notes upon a Change of
                             Control."
 
Ranking..................... The Notes are unsecured senior subordinated
                             obligations of the Company and will rank on a
                             parity with all other unsecured and subordinated
                             indebtedness of the Company and will be
                             subordinated in right of payment to all senior
                             indebtedness of the Company, including
                             indebtedness under the Credit Facility as well as
                             existing and future obligations of the Company's
                             subsidiaries to the extent of the assets of such
                             subsidiaries. After giving pro forma effect to
                             the Reorganization, as of December 31, 1997 the
                             Company would have had outstanding approximately
                             $1.34 billion of Indebtedness (excluding the
                             Notes), all of which would have been Senior
                             Indebtedness, and its subsidiaries would have had
                             approximately $497.4 million of liabilities
                             (excluding Indebtedness owed to the Company).
 
Credit Facility............. In connection with the Reorganization, the
                             Company will enter into a $1.35 billion Credit
                             Facility with a group of banks and borrow $1.25
                             billion thereunder.
 
Common Stock Offering....... Concurrently with the Offering being made hereby,
                             the Company is offering, by means of a separate
                             prospectus, 25,800,000 shares of its Common Stock
                             at an initial offering price of $15.50 per share.
                             The consummation of the Offering being made
                             hereby and the Common Stock Offering is
                             conditioned upon, and will occur simultaneously
                             with, the consummation of the other.
 
                                       8

Certain Covenants........... The Indenture contains certain restrictive
                             covenants which, among other things, restrict the
                             ability of the Company and its Restricted
                             Subsidiaries to incur indebtedness other than
                             Permitted Indebtedness; pay dividends; prepay
                             subordinated indebtedness; repurchase capital
                             stock; incur senior subordinated indebtedness;
                             create certain liens; engage in certain
                             transactions with Affiliates; or sell assets or
                             permit Restricted Subsidiaries to issue certain
                             guarantees. Moreover, the covenants limit the
                             ability of the Company to suffer to exist certain
                             dividend and other payment restrictions affecting
                             its Restricted Subsidiaries or make distributions
                             in respect of the Company's capital stock or make
                             certain other restricted payments. In addition,
                             the Indenture limits the ability of the Company
                             to merge or transfer all or substantially all of
                             its assets. The covenants are, however, subject
                             to a number of important exceptions and
                             qualifications. Certain of these covenants will
                             terminate if and when the Notes are Investment
                             Grade Rated. See "Description of Notes--Certain
                             Covenants."
 
Form of Notes...............
                             The Notes will be issued initially as one or more
                             global securities registered in the name of the
                             nominee of the Depository Trust Company ("DTC").
                             Beneficial interests in the Notes will be shown
                             on, and transfers thereof will be effected only
                             through, records maintained in book-entry form by
                             DTC or its nominee with respect to its
                             participants. Ownership of beneficial interests
                             is limited to persons that have accounts with DTC
                             ("participants") or persons that may hold
                             interest through participants ("indirect
                             participants"). Except as set forth under
                             "Description of Notes," participants or indirect
                             participants are not entitled to receive physical
                             delivery of Notes in definitive form or to have
                             Notes issued and registered in their names and
                             are not considered the owners or holders thereof
                             under the Indenture. See "Description of Notes--
                             Book-Entry; Delivery and Form."
 
Use of Proceeds............. The net proceeds from the Offerings, together
                             with amounts drawn under the Credit Facility,
                             will be used to complete the purchase of the MAC
                             Assets and repay intercompany indebtedness. See
                             "Use of Proceeds."

              SUMMARY HISTORICAL COMBINED FINANCIAL AND OTHER DATA
 
  The following table presents Summary Historical Combined Financial and Other
Data for ZDI and ZDCF as of December 31, 1997 and for the three years then
ended which were derived from the audited combined financial statements of ZDI
and ZDCF included elsewhere in this Prospectus. COMDEX was acquired by Softbank
on April 1, 1995 and ZDI was acquired by Softbank on February 29, 1996; the
Summary Historical Combined Financial and Other Data includes the results of
COMDEX and ZDI from such dates. See "The Reorganization." The following table
also presents pro forma combined financial data of ZDI and ZDCF giving effect
to the transactions described under the heading "The Reorganization" as if they
had occurred as of January 1, 1997, in the case of the statement of operations
data, and as of December 31, 1997, in the case of the balance sheet data. The
pro forma financial data does not purport to be indicative of the results that
actually would have been obtained had the Reorganization been completed as of
such dates and is not intended to be a projection of the future results of
operations or financial position of ZDI and ZDCF. The following information
should be read in conjunction with "Use of Proceeds," "Capitalization,"
"Selected Historical Combined Financial and Other Data," "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Presentation of Financial Information," "Unaudited Pro Forma Combined Financial
Information" and the Combined Financial Statements of ZDI and ZDCF, including
the notes thereto, included elsewhere in this Prospectus.

(1) Due to the subjectivity inherent in the assumptions concerning the timing
    and nature of the uses of cash generated by the pro forma adjustments, cash
    flows from operating, investing and financing activities are not presented
    in the pro forma data.
(2) No historical earnings per share or share data are presented as the Company
    does not consider such data meaningful. Upon closing of the Offering, 100
    million shares of common stock will be outstanding and pro forma earnings
    per share data gives effect to these shares as if they were outstanding on
    January 1, 1997.
(3) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. EBITDA is not intended to represent
    cash flows from operations and should not be considered as an alternative
    to net income as an indicator of the Company's operating performance or to
    cash flows as a measure of liquidity. The Company believes that EBITDA is a
    standard measure commonly reported and widely used by analysts, investors
    and other interested parties in the publishing and media industries.
(4) For purposes of the computations, earnings before fixed charges consist of
    income/(loss) before income taxes adjusted for equity earnings (loss), as
    appropriate, plus fixed charges. Fixed charges are defined as interest
    expense plus that portion of rental expense which is deemed to be
    representative of the interest factor. For the years ended December 31,
    1996, 1997 and Pro Forma 1997 earnings were insufficient to cover fixed
    charges by $26,598, $74,520 and $8,762, respectively.

                                 RISK FACTORS
 
  An investment in the Notes offered hereby involves various risks. Prior to
investing in the Notes being offered hereby, prospective investors should
consider carefully the factors set forth below, together with the other
information set forth in this Prospectus. Certain information contained in
this section and elsewhere in this Prospectus contains forward-looking
statements which involve risks and uncertainties. The Company's actual results
could differ materially from those anticipated in these forward-looking
statements as a result of certain factors set forth in this section and
elsewhere in this Prospectus.
 
RISKS RELATING TO THE REORGANIZATION
 
  The Company is a newly organized Delaware corporation, incorporated on
February 4, 1998 in contemplation of the Reorganization. As part of the
Reorganization, the Company has acquired and will acquire the MAC Assets for
approximately $370 million. Although the Company believes that the purchase
price does not exceed fair market value, such arrangements are not the result
of an arm's length negotiation between unrelated parties, and there can be no
assurance that the Company would not have been able to obtain better terms
from unrelated parties. See "The Reorganization," "Unaudited Pro Forma
Combined Financial Information," "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Certain Transactions."
 
ABSENCE OF HISTORY AS A STAND-ALONE COMPANY; LIMITED RELEVANCE OF HISTORICAL
FINANCIAL INFORMATION
 
  The Company has never operated as a stand-alone company. Until October 1997,
the ZDI and the ZDCF businesses were managed as separate Softbank
subsidiaries. The Company's future operating results will depend in part on
its ability to integrate these businesses and manage the combined enterprise.
In addition, although the Company will be a subsidiary of Softbank following
the Offerings, Softbank will be under no obligation to provide assistance to
the Company or any of its subsidiaries.
 
  The financial information of ZDI and ZDCF included herein does not reflect
what the actual results of operations, financial position and cash flows of
the Company would have been had the Company existed and the Reorganization
been completed prior to the periods presented, nor is it necessarily
indicative of the results of operations, financial position and cash flows of
the Company in the future. The financial statements also include the MAC
Assets which are being transferred to the Company pursuant to the
Reorganization. See "Unaudited Pro Forma Combined Financial Information,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Presentation of Financial Information" and "Certain Transactions."
 
CONTROL BY PRINCIPAL STOCKHOLDERS AND POTENTIAL CONFLICTS OF INTEREST
 
  Upon the completion of the Reorganization, Softbank will own approximately
74.2% of the outstanding shares of Common Stock of the Company (71.4% if the
over-allotment option relating to the Common Stock Offering is exercised in
full). As a result, Softbank will be in a position to direct the election of
all members of the Board of Directors of the Company and to control even those
actions that require the approval of two-thirds or more of the voting share
capital of the Company, including amendments to the Company's Certificate of
Incorporation and any business combinations. Such concentration of ownership
would also have the effect of preventing a change in control of the Company
that might otherwise be beneficial to stockholders. Section 141 of the
Delaware General Corporation Law, however, imposes upon directors a fiduciary
duty to shareholders.
 
  The Company and Softbank have entered into certain agreements governing
various interim and ongoing relationships between Softbank and the Company,
including certain licensing and management agreements relating to
publications, trade shows, ZDTV and ZDNet. In addition, Softbank has given the
Company an undertaking that, as long as it owns 40% of the voting stock of the
Company and can elect a majority of the Board of Directors, it will not expand
operations involving (x) publishing information on computing and Internet-
 
                                      12

related technology through the media of print, CD-ROM/DVD, Internet and
television, or (y) producing trade shows, conferences, exhibitions and similar
events primarily related to computing and Internet-related technology outside
Japan in competition with the Company without the prior approval of the
Company's management directors after consulting with the Company's independent
directors. This undertaking does not preclude investments by investment funds
managed by Softbank. Softbank manages certain venture capital funds which
invest in, among other things, computer and Internet-related companies. These
funds may be able to co-invest with the Company or compete with the Company
with respect to new investments. Softbank may develop new funds in the future,
which funds may compete with the Company for investment opportunities. The
Company has undertaken not to compete with Softbank in Japan without the prior
approval of SOFTBANK Corp.'s Board of Directors and to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. Such arrangements and undertaking are not the result of an arm's length
negotiation between unrelated parties. See "--New Product Risks," "The
Company--Relationship with Softbank," "Certain Transactions" and "Principal
Stockholders."
 
SIGNIFICANT DEBT OBLIGATIONS; RESTRICTIVE COVENANTS
 
  At December 31, 1997, on a pro forma basis after giving effect to the
Reorganization described under "Unaudited Pro Forma Combined Financial
Information," the Company's total debt was approximately $1.594 billion, its
total stockholders' equity was approximately $1.441 billion, its earnings were
insufficient to cover fixed charges by $8.8 million and its total debt was
52.5% of total capitalization. The Company's indebtedness is substantial in
relation to its stockholders' equity. The degree to which the Company is
leveraged could have important consequences to holders of Notes because: (i)
the Company's ability to obtain additional financing in the future for working
capital, capital expenditures, acquisitions or general corporate purposes may
be impaired; (ii) the funds available to the Company for its operations may be
reduced if a substantial portion of the Company's cash flow from operations is
dedicated to the payment of principal and interest on its indebtedness; and
(iii) the Company's ability to incur additional debt may be impaired because
the Credit Facility and the Notes contain financial and other restrictive
covenants. The indebtedness of the Company requires a substantial portion of
the Company's cash flow to be dedicated to the payment of principal and
interest on indebtedness, thereby reducing funds available for capital
expenditures and future business opportunities. In addition, the Company's
indebtedness could increase the Company's vulnerability to adverse general
economic conditions (including increases in interest rates) and could impair
the Company's ability to take advantage of significant business opportunities
that may arise. Subject to certain limitations, the Credit Facility and the
Indenture will permit the Company and its subsidiaries to incur additional
indebtedness.
 
  The ability of the Company to service its indebtedness, and to comply with
the financial and restrictive covenants contained in the Credit Agreement and
the Indenture, is dependent upon the Company's future performance and business
growth which are subject to financial, economic, competitive, regulatory and
other factors affecting the Company, many of which are beyond its control.
While the Company believes that it will be able to generate sufficient cash
flow to cover required debt service payments, no assurance can be given to
that effect. If the Company is unable to generate sufficient funds to meet its
debt service obligations, it may be required to refinance some or all of such
debt, sell assets or raise additional equity. No assurance can be given that
such refinancings, asset sales or equity sales could be accomplished or, if
accomplished, would raise sufficient funds to meet its debt service
obligations. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources" and "Description
of the Credit Facility." In addition, a downturn in general economic
conditions or in its business could have a material adverse effect on the
Company's ability to meet its debt service obligations or to conduct its
business in the ordinary course.
 
  The Credit Facility will contain financial covenants which, among other
things, will require the Company to maintain certain financial ratios and
restrict the ability of the Company and certain of its subsidiaries to incur
indebtedness, make acquisitions or investments, and create or permit liens.
The Indenture will contain covenants
 
                                      13
<PAGE>
 
which restrict the Company from incurring additional indebtedness, making
certain restricted payments, creating liens on its assets, making certain
asset dispositions and entering into certain transactions with affiliates. If
the Company is unable to generate sufficient cash flow or otherwise obtain the
funds necessary to make required payments of principal and interest under, or
is unable to comply with the covenants of, the Credit Facility or the
Indenture, the Company could be in default under the terms thereof, which
would permit the lenders pursuant to the Credit Facility to accelerate the
maturity of the Senior Indebtedness created pursuant thereto and receive
payment in full prior to the receipt by the Holders of Notes of any payment of
principal of, premium, if any, and interest on the Notes. See "Description of
the Credit Facility" and "Description of Notes."
 
SUBORDINATION OF THE NOTES; DEPENDENCE ON SUBSIDIARIES
 
  The Notes will be subordinated to all Senior Indebtedness including all
obligations under the Credit Facility. In the event of a circumstance in which
the contractual subordination provisions apply, Holders of Notes will not be
entitled to receive and will have an obligation to pay over to holders of
Senior Indebtedness any payments they may receive in respect of the Notes. As
of December 31, 1997, on a pro forma basis after giving effect to the
Reorganization, the Company would have had outstanding an aggregate principal
amount of approximately $1.34 billion of Senior Indebtedness, which would rank
senior in right of payment to the Notes. Furthermore, subject to certain
limitations, the Credit Facility and the Indenture will permit the Company and
its subsidiaries to incur additional indebtedness, including Senior
Indebtedness. The indebtedness under the Credit Facility will become due prior
to the time the principal obligations under the Notes become due. Certain
subsidiaries of the Company will issue guarantees under the Credit Facility
which will be secured by a pledge of the equity interests in other
subsidiaries owned by them and the Company has pledged the issued and
outstanding capital stock of certain of its subsidiaries to secure
Indebtedness under the Credit Agreement. If the lenders under the Credit
Facility should attempt to foreclose on the collateral thereunder, the
Company's financial condition and the value of the Notes could be materially
adversely affected. In the event of a bankruptcy, liquidation or
reorganization of the Company, the assets of the Company would be available to
pay obligations on the Notes only after all Senior Indebtedness has been paid
in full, and there may not be sufficient assets remaining to pay amounts due
on any or all of the Notes then outstanding. See "Description of the Credit
Facility" and "Description of Notes."
 
  In addition, the operations of the Company are conducted through its
subsidiaries. Therefore, the Company's ability to make required principal and
interest payments with respect to the Company's indebtedness, including the
Notes, depends on the earnings of its subsidiaries and on its ability to
receive funds from such subsidiaries through dividends or other payments. The
Notes are obligations exclusively of the Company. The Company's subsidiaries
are separate and distinct legal entities and are not obligated or required to
pay any amounts due pursuant to the Notes or to make funds available therefor
in the form of dividends or advances to the Company. Applicable law of the
jurisdictions in which the Company has organized or may organize subsidiaries
may limit such subsidiaries' ability to pay dividends. Furthermore, the Notes
effectively will be subordinated to all outstanding indebtedness and other
liabilities and commitments (including trade payables and operating lease
obligations) of the Company's subsidiaries. Any right of the Company to
receive assets of any of its subsidiaries upon the latter's liquidation or
reorganization (and the consequent right of Holders of Notes to participate in
those assets) effectively will be subordinated to the claims of that
subsidiary's creditors, except to the extent that the Company itself is
recognized as a creditor of such subsidiary, in which case the claims of the
Company would still be subordinate to any security interest in the assets of
such subsidiary and any indebtedness of such subsidiary senior to that held by
the Company. As of December 31, 1997, on a pro forma basis as described above,
the Company's subsidiaries would have had approximately $497.4 million of
liabilities (excluding Indebtedness to the Company) .
 
DEPENDENCE ON DEMAND FOR ADVERTISING
 
  A significant portion of the Company's total revenue in 1997 (51.9%) was
derived from advertising sales. Should a general economic downturn or a
recession in the United States occur in the future, the Company's
 
                                      14
<PAGE>
 
advertisers may reduce their advertising budgets. In addition, technology
product advertisers may be affected by factors such as pricing pressures and
new product launches. Furthermore, there can be no assurance that technology
product advertisers will maintain current levels of advertising in special
interest magazines and events as opposed to general interest media such as
newspapers, television and Internet sites. Any material decline in the demand
for advertising by technology product advertisers could have an adverse effect
on the Company's financial condition and results of operations.
 
IMPORTANCE OF CERTAIN PUBLICATIONS AND TRADE SHOWS
 
  Certain of the Company's publications have represented a significant portion
of the Company's historic revenue, and the Company expects that such
publications will continue to do so in the future. The Company's business
publications, which include such titles as PC Magazine, Computer Shopper and
PC Week, accounted for 65.3% of the Company's publishing revenue in 1997.
Although the Company believes it has a diversified portfolio of special-
interest publications and is not dependent on any single publication, a
significant decline in the performance of any of these publications could have
an adverse effect on the Company's financial condition and results of
operations. See "Business--Print Publishing--Sources of Print Publishing
Revenue."
 
  Certain of the Company's trade shows and conferences have represented a
significant portion of the Company's historic revenue, and the Company expects
that such trade shows and conferences will continue to do so in the future.
COMDEX/Fall accounted for 34.0% of the Company's trade show and conference
revenue in 1997. Although the Company believes it has a diversified portfolio
of trade shows worldwide, a significant decline in the performance of
COMDEX/Fall could have an adverse effect on the Company's financial condition
and results of operations. See "Business--Trade Shows and Conferences--Sources
of Trade Show and Conference Revenue."
 
SEASONALITY OF REVENUE; FLUCTUATIONS IN REVENUE FROM PERIOD TO PERIOD;
ANTICIPATED LOSS FOR FIRST QUARTER OF 1998
 
  The Company's business is seasonal, with revenue typically reaching its
highest level during the fourth quarter of each calendar year, largely due to
the timing of its single largest trade show event, COMDEX/Fall, and the
increase in publishing revenue in the fourth quarter due to increased consumer
buying activity during the holiday season. In 1997, 35.0% of the Company's
revenue was generated during the fourth quarter, with the first, second and
third quarters accounting for 19.5%, 26.1% and 19.4% of revenue, respectively.
In addition, the Company may experience fluctuations in revenue from period to
period based on levels of marketing expenditure by the Company's advertising
customers and by competition among computer technology marketers. Many of the
Company's large customers concentrate their advertising expenditures around
major new product launches. Marketing expenditure by technology companies can
also be affected by factors affecting the computer industry generally,
including changes in end user demand, pricing pressures and inventory
surpluses. Furthermore, the Company's results are affected by the number and
timing of new product launches and the timing of events. The launch of new
publications, trade shows and services are funded with cash flow from
operations and are expensed as incurred. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Overview" and "--
Seasonality."
 
  For the first quarter of 1998, the Company will report a loss from
operations of $24 million as compared with a loss from operations of $15.6
million for the first quarter of 1997. There are several factors influencing
the lower operating results for the first quarter of 1998, including lower
advertising revenue in the Company's business publications as a result of
factors affecting the computer technology industry generally (substantially
offset by revenue from trade shows which were not held in the comparable
period of the prior year) and certain one-time costs occurring in the first
quarter of 1998. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Three Months Ended March 31, 1998
Compared With Three Months Ended March 31, 1997 (unaudited)."
 
                                      15
<PAGE>
 
HISTORICAL NET LOSSES
 
  The Company had net losses of $52.1 million and $71.2 million for the twelve
months ended December 31, 1996 and 1997, respectively. On a pro forma as
adjusted basis giving effect to the Reorganization, the Company had a net loss
of $9.1 million, or $(.09) per share, for the twelve months ended December 31,
1997. See "Unaudited Pro Forma Combined Financial Information." There can be
no assurance that the Company will report net income in the future.
 
NEW PRODUCT RISKS
 
  The Company's future success will depend in part on its ability to monitor
rapidly changing technologies and market trends and offer new publications,
trade shows and services that address the needs of specific target audiences.
The process of internally researching and developing, launching, acquiring
acceptance and establishing profitability for a new publication, trade show or
service, or assimilating and marketing an acquired publication, trade show or
service, can be risky and costly. There can be no assurance that the Company's
efforts to introduce new or assimilate acquired publications, trade shows or
services will be successful or profitable. In addition to its publications,
trade shows and services, the Company is a leading provider of Internet
content about computing services, primarily through its ZDNet online service.
The Internet is still in the relatively early stages of development;
therefore, there can be no assurance that the Company's Internet services will
remain competitive. Costs related to the development of new products are
expensed as incurred and, accordingly, the Company's profitability from year
to year may be adversely affected by the number and timing of new product
launches. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
  The Company has entered into a license and services agreement with MAC to
develop ZDTV. ZDTV is indirectly owned by MAC, but as part of this license and
services agreement MAC has granted the Company an option exercisable through
December 31, 1998 to purchase all of MAC's interest in ZDTV for an amount
equal to MAC's investment plus 10% per annum for the period of its investment.
The Company does not intend to exercise the option unless ZDTV has secured
sufficient cable carriage. This may include entering into a joint venture or
other co-ownership arrangement. The Company is currently funding ZDTV's
operations on behalf of MAC through unsecured advances which, for approved
levels of expenditure, are to be reimbursed by MAC. ZDTV's cash requirements
are expected to be approximately $54 million in 1998. There can be no
assurance that MAC will continue to approve and reimburse the Company for
expenditures or that the Company will exercise its option. If the Company
exercises its option, there can be no assurance that ZDTV will ultimately
obtain sufficient cable carriage and commercial acceptance to be profitable.
See "The Company--Relationship with Softbank" and "Certain Transactions."
 
RISKS ASSOCIATED WITH FLUCTUATIONS IN PAPER AND POSTAGE COSTS
 
  The Company's principal raw material is paper. Paper costs constitute a
significant expense, accounting for 15.2% of the Company's total U.S. print
publishing operating expenses in 1997. Paper prices have been volatile over
the past several years, initially rising in 1994, rising more significantly in
1995 and 1996 and declining in 1997. Management anticipates paper prices will
increase in 1998. The Company does not use forward contracts and most of its
paper supply contracts, which are generally for a two to three year renewable
term, provide for price adjustments to reflect changing market prices.
Accordingly, significant increases in paper prices could adversely affect the
Company's future results of operations.
 
  Postage for magazine distribution is also a significant expense for the
Company, accounting for 11.3% of the Company's total U.S. print publishing
operating expenses in 1997. Postage costs increase periodically and can be
expected to increase in the future. The United States Postal Service has
recently announced a 5.4% increase for commercial magazine rates, which is
expected to become effective in 1998. The Company may not be able to recover,
in whole or in part, paper or postage cost increases. Accordingly, significant
cost increases
 
                                      16
<PAGE>
 
could have an adverse effect on the Company's financial condition or results
of operations. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business--Print Publishing--Paper
and Printing."
 
COMPETITION
 
  The Company faces significant competition with respect to its print
publications, trade shows and conferences and other technology information
services. In its publishing business, the Company principally competes for
advertising and circulation revenue with publishers of other computer
technology publications, and also faces broad competition from media companies
that produce general interest magazines, newspapers and online content.
Overall competitive factors include product positioning, editorial quality,
circulation, price and customer service. Competition for advertising dollars
is primarily based on advertising rates, the nature and scope of readership,
reader response to advertisers' products and services and the effectiveness of
sales teams. In its trade show and conference business, the Company competes
with other producers of trade shows and conferences for exhibition space,
exhibitors and attendees, primarily on the basis of the quality of the
conference, its content and organizational efficiency. If the Company is
unable to compete effectively for advertisers, readers, exhibitors and/or
attendees, its financial condition and results of operations could be
adversely affected. See "Business--Competition."
 
CONSOLIDATION OF PRINCIPAL VENDORS; SIGNIFICANT SUPPLIER
 
  The Company's principal vendors include paper suppliers, printers,
fulfillment houses and national newsstand distributors. Each of these
industries is currently experiencing consolidation among their principal
participants. Such consolidation may result in: (i) decreased competition,
which may lead to increased prices; (ii) interruptions and delays in services
provided by such vendors; and (iii) greater dependence on certain vendors.
Such factors could adversely affect the Company's results of operations. One
printing company accounted for approximately 50% of the Company's total print
publishing manufacturing expenditures in 1997 for its U.S.-based publications.
While the Company believes there are adequate alternatives available, an
interruption or delay in service from, or the loss of, this printer could have
an adverse effect on the Company. See "Business--Print Publishing--Paper and
Printing."
 
RISKS ASSOCIATED WITH INTERNATIONAL EXPANSION
 
  One component of the Company's growth strategy is to further expand into
international markets. 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
fluctuations, state-imposed restrictions 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 an adverse effect on the Company's future
international operations and, consequently, on the Company's financial
condition and results of operations. See "Business --Print Publishing--
International Publications" and "Business--Trade Shows and Conferences."
 
POSSIBLE INABILITY TO REPURCHASE NOTES UPON CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, each Holder of Notes will have
the right to require the Company to repurchase all or any part of such
Holder's Notes at an offer price in cash equal to 101% of the aggregate
principal amount thereof, plus accrued and unpaid interest, if any, thereon to
the date of repurchase. No assurance can be given that the Company will have
sufficient resources to satisfy its repurchase obligation with respect to the
Notes following a Change of Control. See "Description of the Notes--Certain
Covenants--Repurchase of Notes upon a Change of Control."
 
  The Credit Facility will prohibit the Company from purchasing the Notes
(except in certain limited circumstances beginning in the year 2000) and will
also provide that certain change of control events with respect
 
                                      17
<PAGE>
 
to the Company will constitute a default thereunder. Any future credit
agreements or other agreements relating to Senior Indebtedness to which the
Company becomes a party may contain similar restrictions and provisions. In
the event a Change of Control occurs at a time when the Company is prohibited
from purchasing the Notes, the Company could seek the consent of its lenders
to the purchase of the Notes or could attempt to refinance the borrowings that
contain such prohibition. If the Company does not obtain such consent or repay
such borrowings, the Company will remain prohibited from purchasing the Notes
by the relevant Senior Indebtedness. In such case, the Company's failure to
purchase the tendered Notes would constitute an event of default under the
Indenture and the Company's failure to make an offer to purchase would permit
the Holders of the Notes to declare the principal of, premium if any, and
accrued interest on the Notes immediately due and payable under the Indenture.
Such an event would constitute a default under the Credit Facility and could
constitute a default under other Senior Indebtedness. In such circumstances,
the subordination provisions in the Indenture would likely restrict payments
to the Holders of the Notes. See "Description of the Notes."
 
NO PRIOR PUBLIC MARKET FOR THE NOTES
 
  The Notes are a new issue of securities for which there is currently no
market. If the Notes are traded after their initial issuance, they may trade
at a discount from their initial offering price, depending upon prevailing
interest rates, the market for similar securities and other factors. The
Underwriters have informed the Company that, subject to applicable laws and
regulations, they currently intend to make a market in the Notes. However, the
Underwriters are not obligated to do so, and any such market making may be
discontinued at any time without notice. Therefore, no assurance can be given
as to whether an active trading market will develop for the Notes. The Company
does not intend to apply for listing of the Notes on any securities exchange
or on the National Association of Securities Dealers, Inc. automated quotation
system. See "Underwriters."

<PAGE>
 
                                  THE COMPANY
 
  The Company believes it is the world's preeminent integrated media and
marketing company focused on computing and Internet-related technology, with
principal platforms in print publishing, trade shows and conferences, online
content, market research and education. The Company's 28 primary U.S. and
international titles, including its joint ventures, and over 50 licensed
publications, total more than 80 publications distributed worldwide, with a
combined circulation of more than eight million primary readers. The Company's
predecessor was founded in 1927 and pioneered the development of special-
interest magazines, including Car and Driver, Popular Photography, Stereo
Review, Boating, Skiing and Modern Bride. The Company also produces the
world's most important trade shows related to computer technology, with over
two million estimated attendees at over 50 trade shows and conferences
worldwide in 1997. The Company's COMDEX/Fall event is the number one ranked
trade show for all industries in the U.S. as measured by total revenue, total
exhibit space and number of attendees. The Company's ZDNet.com Web site is the
leading computing content site and ranked the number one Web site in 1997 in
the category of news, information and entertainment, as measured by visitors
per month. The Company's other media and marketing platforms include market
research, education and the publication of computer-related newsletters,
training manuals and materials.
 
  The Company's principal executive offices are located at One Park Avenue,
New York, New York 10016 and its telephone number is (212) 503-3500.
 
RELATIONSHIP WITH SOFTBANK
 
  The Company is an indirect subsidiary of SOFTBANK Corp., which, as of
December 31, 1997, was 50.2% owned by Mr. Masayoshi Son, its President,
including 43.4% directly held by his 99% owned holding company, MAC. Softbank
is a leading provider of information and distribution services as
infrastructure for the digital information industry. Softbank is Japan's
leading distributor of computer software as well as a leading publisher of
Japanese computer technology publications. It also is an 80% owner of Kingston
Technology Company ("Kingston"), one of the world's largest independent
providers of computer memory modules; a founder and co-owner of Japan Sky
Broadcasting Co., Ltd. ("JSkyB"), a digital satellite broadcasting venture in
Japan; a shareholder, directly or through its investment fund affiliates, in
over 50 network and computer-related venture businesses in the digital
information industry; and a 29.4% owner of Yahoo! Inc.
 
  Upon the completion of the Reorganization, Softbank will own approximately
74.2% of the outstanding shares of Common Stock (71.4% if the overallotment
option relating to the Common Stock Offering is exercised in full). The
Company and Softbank have entered into certain agreements governing various
interim and ongoing relationships between Softbank and the Company, including
certain licensing and management agreements relating to publications, trade
shows, ZDTV and ZDNet. See "Certain Transactions."
 
  In addition, Softbank has given the Company an undertaking that, as long as
it owns 40% of the voting stock of the Company and can elect a majority of the
Board of Directors, it will not expand operations involving (x) publishing
information on computing and Internet-related technology through the media of
print, CD-ROM/DVD, Internet and television, or (y) producing trade shows,
conferences, exhibitions and similar events primarily related to computing and
Internet-related technology outside Japan in competition with the Company
without the prior approval of the Company's management directors after
consulting with the Company's independent directors.
 
  This undertaking does not preclude investments by investment funds managed
by Softbank. Softbank manages certain venture capital funds which invest in,
among other things, computer and Internet-related companies. These funds may
be able to co-invest with the Company or compete with the Company with respect
to new investments. Softbank may develop new funds in the future, which funds
may compete with the Company for investment opportunities. The Company has
undertaken not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s Board of Directors and has agreed to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest" and "Certain Transactions."
 
                                      19
<PAGE>
 
  In order to expand its media platforms, the Company has entered into a
license and services agreement with MAC to develop ZDTV, a 24-hour cable
television channel and integrated Web site focused exclusively on computers,
technology and the Internet. ZDTV is indirectly owned by MAC, but as part of
this license and services agreement MAC has granted the Company an option
exercisable through December 31, 1998 to purchase all of MAC's interest in
ZDTV for an amount equal to MAC's investment plus 10% per annum for the period
of its invesment. Pursuant to the license and services agreement, the Company
has agreed to fund ZDTV's operations on behalf of MAC through unsecured
advances which, for approved levels of expenditure, are to be reimbursed by
MAC. Such advances bear interest at the 30-day LIBOR rate plus .50%. ZDTV's
cash requirements are expected to be approximately $54 million in 1998. The
Company's cumulative advances in respect of ZDTV, which totaled $14.4 million
net of $10.1 million in repayments through December 31, 1997, will be repaid
concurrently with the Reorganization. The Company has not yet determined
whether it will exercise its option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon securing sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Company. ZDTV is not included in the
Company's results of operations. See "Certain Transactions."
 
                                      20
<PAGE>
 
                              THE REORGANIZATION
 
  The businesses to be conducted by the Company were acquired in a series of
acquisitions and internal reorganizations undertaken by Softbank. See "The
Company--Relationship with Softbank." The Company's principal business
operations are as follows:
 
    (i) the computer technology publishing operations of Ziff-Davis
  Publishing Company ("ZD Pubco"), which Softbank acquired in February 1996
  for $1.8 billion in cash and subsequently renamed Ziff-Davis Inc.;
 
    (ii) the COMDEX computer-related trade show operations ("COMDEX"), which
  Softbank acquired in April 1995 for $803 million in cash and renamed
  SOFTBANK COMDEX Inc. ("SB COMDEX"); and
 
    (iii) the computer and network-related trade show operations of Ziff-
  Davis Exposition and Conference Company ("ZD Expos"), which Softbank
  acquired in December 1994 for $127 million in cash and subsequently renamed
  SOFTBANK Forums Inc. ("SB Forums").
 
  Concurrently with the ZD Pubco and ZD Expos acquisitions described above,
MAC purchased certain operations and assets of these companies for $302
million and $75 million, respectively. The MAC Assets consist of certain
international consumer and Internet publications, international trade shows
and the ZDNet business, most of which were still under development. The MAC
Assets and related operations have been managed by ZDI and ZDCF since their
acquisition by MAC. As part of the Reorganization discussed below, the MAC
Assets, except for those that have been discontinued, have been or will be
acquired by the Company at a purchase price that does not exceed fair market
value. A portion of the MAC Assets was acquired by the Company on October 31,
1997 for $100 million, and the balance will be sold to the Company
concurrently with the Offerings. See "Use of Proceeds."
 
  In October 1997, Softbank decided to combine the businesses of ZDI, SB
COMDEX and SB Forums. SB Forums and SB COMDEX were merged as of December 31,
1997, with the surviving corporation named ZDCF. In order to complete the
combination and establish the Company as a separate public company,
concurrently with the Offerings, ZDI and ZDCF will be contributed to the
Company in exchange for 74.2% of the Company's Common Stock, and approximately
$929 million of the Company's obligations to Softbank will be converted to
equity at the initial public offering price. The amount of intercompany
indebtedness to be converted to equity is comprised of the obligations due to
Softbank as of December 31, 1997, except those repaid with borrowings under
the Credit Facility and the proceeds of the Notes Offering and a $94.2 million
note which matures on February 28, 2009. At an initial public offering price
of $15.50 per share, the value of the capitalized intercompany indebtedness
will be equivalent to 59.9 million shares of Common Stock. In addition, the
Company will receive approximately $9.1 million of fixed assets from Kingston
in exchange for 580,645 shares of the Company's Common Stock (valued at the
initial public offering price) and $100,000, which assets will be subsequently
leased back to Kingston.
 
  As part of the Reorganization, the Company will: (i) issue 25.8 million
shares of its Common Stock in the Common Stock Offering; (ii) sell $250
million aggregate principal amount of its 8 1/2% Senior Subordinated Notes due
2008 in the Offering; and (iii) enter into the $1.35 billion Credit Facility
and borrow $1.25 billion thereunder. The Company will use the net proceeds
from the Offerings and the Credit Facility to (i) pay $270 million to MAC,
representing the purchase price for the remaining MAC Assets, and (ii) repay
approximately $1.587 billion of obligations to Softbank (including the
Company's liability to Softbank with respect to the $100 million purchase
price for the initial portion of the MAC Assets, net of the approximately $42
million of balances due from MAC in connection with funding for the MAC Assets
and ZDTV through December 31, 1997), which payment will eliminate all except
$94.2 million of the remaining intercompany indebtedness as of December 31,
1997. The Company has obtained a commitment letter from The Bank of New York,
Morgan Stanley Senior Funding, DLJ Capital Funding and The Chase Manhattan
Bank to provide such Credit Facility.
 
  Unless the context otherwise indicates, references herein to the
"Reorganization" include all of the transactions described above. The
Offerings will be conditioned upon the completion of all such transactions
comprising the Reorganization, which shall be deemed to occur simultaneously.

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the Notes and the Common
Stock are estimated to be $241.3 million and $377.4 million ($434.4 million if
the over-allotment option relating to the Common Stock Offering is exercised
in full), respectively, after deducting underwriting discounts and commissions
and estimated offering expenses payable by the Company. The Company intends to
use the proceeds from the Offerings and approximately $1.25 billion in
borrowings under the Credit Facility, to fund the approximately $270 million
purchase price of the balance of the MAC Assets (see "Risk Factors--Risks
Relating to the Reorganization") and repay approximately $1.587 billion of
intercompany obligations.

(1) Historical Combined Financial and Other Data of ZDI has been presented for
    all periods prior to its acquisition by Softbank on February 29, 1996 as
    it represents the Company's principal operations.
(2) Reflects operations of SB Forums for the year and COMDEX from the date of
    acquisition by Softbank on April 1, 1995.
(3) Reflects operations of SB Forums and COMDEX for the year and ZDI from the
    date of acquisition by Softbank on February 29, 1996.
(4) For the years ended December 31, 1993 and 1994, the operations of ZDI were
    conducted through various partnerships. Accordingly, no income taxes have
    been provided.
(5) No historical earnings per share or share data are presented as the
    Company does not consider such data meaningful.
(6) For purposes of the computations, earnings before fixed charges consist of
    income/(loss) before income taxes adjusted for equity earnings/losses as
    appropriate, plus fixed charges. Fixed charges are defined as interest
    expense plus that portion of rental expense which is deemed to be
    representative of the interest factor. For the year ended December 31,
    1995 and the two-month period ended February 28, 1996, ZDI's earnings were
    insufficient to cover fixed charges by $36,859 and $6,760, respectively.
    For the years ended December 31, 1996 and 1997, ZDI and ZDCF's earnings
    were insufficient to cover fixed charges by $26,598 and $74,520,
    respectively.

              UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
 
  The following Unaudited Pro Forma Combined Financial Information (the "Pro
Forma Financial Information") is based on the historical combined financial
statements of ZDI and ZDCF and has been prepared to illustrate the effects of
the Reorganization and the other transactions described below.
 
  The Unaudited Pro Forma Combined Statement of Operations for the year ended
December 31, 1997 gives effect to the Reorganization as if it had occurred as
of January 1, 1997. The Unaudited Pro Forma Combined Balance Sheet as of
December 31, 1997 has been prepared as if the Reorganization had occurred on
that date. See "The Reorganization."
 
  The Pro Forma Financial Information is not necessarily indicative of the
actual results of operations or financial position of the Company at December
31, 1997 and does not purport to represent the Company's results of operations
for future periods or its future financial position.
 
  The Pro Forma Financial Information should be read in conjunction with the
Historical Combined Financial Statements of ZDI and ZDCF and notes thereto
which are included elsewhere in this Prospectus. In management's opinion, the
Pro Forma Financial Information includes all adjustments necessary to reflect
the effects of the Reorganization and other transactions described below.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  The Company operates in two business segments: (i) publishing and (ii) trade
shows and conferences. The Company believes it is the world's preeminent
integrated media and marketing company focused on computing and Internet-
related technology, with principal platforms in print publishing, trade shows
and conferences, online content, market research and education. The Company's
28 primary U.S. and international titles, including its joint ventures, and
over 50 licensed publications, total more than 80 publications distributed
worldwide, with a combined circulation of more than eight million primary
readers. The Company also produces the world's most important trade shows
related to computer technology, with over two million estimated attendees at
over 50 trade shows and conferences worldwide in 1997. The Company's
COMDEX/Fall event is the number one ranked trade show for all industries in
the U.S. as measured by total revenue, total exhibit space and number of
attendees. The Company's ZDNet.com Web site is the leading computing content
site and ranked the number one Web site in 1997 in the category of news,
information and entertainment, as measured by visitors per month. The
Company's other media and marketing platforms include market research,
education and the publication of computer-related newsletters, training
manuals and materials.
 
  The Company had net revenue of $1.154 billion for 1997. A substantial
portion of the Company's revenue is derived from the sale of advertising,
which in 1997 accounted for 51.9% of total revenue. No single advertiser has
comprised more than 3% of the Company's advertising revenue during any of the
last three years. However, the Company's top 20 advertisers accounted for
32.1% of total advertising revenue for 1997.
 
  In the publishing segment, the Company's principal sources of revenue are
advertising (67.3% of 1997 total publishing revenue), circulation (17.4%) and
other (15.3%). Circulation comprises both paid subscriptions (10.8%) and
newsstand sales (6.6%) while other includes educational and training materials
(5.4%) and market research studies (6.2%) with the balance primarily
consisting of royalties, reprints and other miscellaneous sales. In the trade
shows and conferences segment, revenue is derived from two principal sources:
sale of exhibit space (64.8% of 1997 total segment revenue) and attendee
conference and seminar fees (14.9%). Unlike many trade show producers, the
Company derives a significant portion of its trade show revenue from other
sources (20.3%), including advertising in show-related publications,
billboards, banners, fees from managing customer-sponsored events and other
show-related activities. The Company believes these other sources will
continue to be an important growth area, particularly for its content-focused
events.
 
  In the publishing business, the principal components of the Company's
production costs are raw materials, printing and distribution, which
represented 34.6%, 37.5% and 26.7%, respectively, of total 1997 publishing
production expenses. The Company's principal raw material is paper. Paper
supply and prices are subject to volatility and may be significantly affected
by many factors, including market and economic conditions. See "Risk Factors--
Risks Associated with Fluctuations in Paper and Postage Costs" and "--
Inflation and Change in Paper Prices." The principal components of production
costs within the trade shows and conferences business are the costs of renting
and preparing the facilities to hold the events (33.6%), direct mail and the
related costs for promotion of the events (33.2%) and program development and
presentation costs (11.3%).
 
  The other principal operating costs for the Company are selling, general and
administrative expenses, including editorial costs. Included in these costs
are salaries, sales commissions and benefits (49.8%) along with marketing and
promotion expenses related to advertising and circulation (18.8%).
 
  The Company's revenue and profitability are influenced by a number of
external factors, including the volume of new technology product
introductions, the amount and allocation of marketing expenditure by the
Company's clients, the extent to which sellers elect to advertise using print
and online media or participate in trade shows and conferences, changes in
paper prices, availability of appropriate venues for its largest trade shows
and conferences and competition among computer technology marketers (including
print publishers, producers of trade shows and providers of other technology
information services). Accordingly, the Company may experience fluctuations in
revenue from period to period. Many of the Company's large customers
concentrate their advertising expenditures around major new product launches.
Marketing expenditures by technology companies can also be affected by factors
affecting the computer industry generally, including pricing
 
                                      30

pressures and temporary surpluses of inventory. Revenue and profitability are
also influenced by product mix and the timing and frequency of the Company's
new product launches and launches in new markets, as well as by acquisitions.
New publications generally require several years to achieve profitability and
upon achieving initial profitability, often have lower margins than more
established publications. The launch of new publications, trade shows and
services are funded with cash flow from operations and are expensed as
incurred. Accordingly, the Company's revenue from year to year may be affected
by the number and timing of new product launches. If the Company concludes
that a new publication, trade show or service will not achieve certain
milestones with regard to revenues, profitability and cash flow within a
reasonable period of time, management may discontinue such publication, trade
show or service or merge it into another existing publication, trade show or
service. See "Risk Factors--New Product Risks."
 
  The Company's taxable income for 1998 will be greater than the pre-tax
income reported in its financial statements. The difference results from
certain items which are non-deductible for income taxes, primarily losses
generated from the MAC Assets prior to transfer to the Company and non-
deductible goodwill amortization (see Note 8 to the Combined Financial
Statements of ZDI and ZDCF). Consequently, the Company's effective tax rate
for the year will be significantly in excess of the statutory rates. In
accordance with generally accepted accounting principles, the Company will
record income taxes on a quarterly basis at the estimated annual effective tax
rate. As a result, the Company expects to record income tax benefits in
quarters where pre-tax losses are incurred and income tax expense in periods
where pre-tax profits are generated.
 
  Historically, the financing requirements of the Company have been funded
through intercompany loans and advances, totaling $2.5 billion at December 31,
1997, of which $126 million was current. As a result of the Reorganization,
the Company's intercompany debt owed to Softbank will be reduced to $94.2
million. Such indebtedness bears interest at 9.9% and matures in February
2009. Concurrently with the Offerings, the Company will enter into the $1.35
billion Credit Facility and borrow $1.25 billion thereunder. See "--Liquidity
and Capital Resources."
 
PRESENTATION OF FINANCIAL INFORMATION
 
  ZD Inc. was incorporated on February 4, 1998. Concurrent with the completion
of the Offerings, all of the common stock of ZDI and ZDCF, the Company's
principal operating subsidiaries, will be contributed to the Company.
 
  These subsidiaries were acquired in a series of acquisitions and internal
reorganizations undertaken by the Company's principal stockholder, Softbank.
In December 1994, Softbank acquired SB Forums for $127 million in cash. The
acquisition was accounted for using the purchase method of accounting and
accordingly, the results of operations of SB Forums are included in the
Combined Financial Statements of ZDI and ZDCF for 1995, 1996 and 1997.
 
  In April 1995, SOFTBANK acquired SB COMDEX for $803 million in cash, plus
transaction costs. The acquisition was accounted for using the purchase method
of accounting and accordingly, SB COMDEX's results are included in the
Combined Financial Statements since the date of acquisition. As of December
31, 1997, SB Forums and SB COMDEX were merged, with the surviving corporation
named ZD Comdex and Forums (ZDCF).
 
  In February 1996, Softbank acquired Ziff-Davis Publishing Company
(subsequently renamed Ziff-Davis Inc.) for $1.8 billion in cash. The
acquisition of ZDI has been accounted for using the purchase method of
accounting and accordingly, the results of ZDI are included in the Combined
Financial Statements since the date of acquisition. ZDI's results of
operations for periods prior to the date of acquisition are set forth in the
ZDI Financial Statements included elsewhere in this Prospectus.
 
  In connection with the acquisition of SB Forums and ZDI described above,
MAC, Softbank's largest shareholder, purchased certain operations and assets
of these companies for $75 million and $302 million, respectively. The MAC
Assets consist of certain international publications, consumer and Internet
publications, international trade shows and the ZDNet business, most of which
were still under development. As part of the Reorganization, the MAC Assets,
except for those which have been discontinued, have been or will be sold to
the Company. The acquisition of the MAC Assets has been accounted for in a
manner similar to a pooling of interests and is reflected in the Combined
Financial Statements of ZDI and ZDCF for all periods presented.
 
                                      31
<PAGE>
 
  Due to the acquisition of ZDI on February 29, 1996 and the resulting
revaluation of assets and liabilities and the change in the Company's capital
structure, the historical financial statements of ZDI and ZDCF are not
directly comparable. The table below presents the Company's pro forma results
for 1996 and 1995 as if ZDI and ZDCF had been under common control since
January 1, 1995. The results of SB COMDEX are included since April 1, 1995.
The combined results for 1995 and 1996 were derived by combining the statement
of operations for ZDI for the year ended December 31, 1995 and for the period
January 1, 1996 to February 28, 1996 with the combined statement of operations
for ZDI and ZDCF for the years ended 1995 and 1996. In addition, the purchase
accounting adjustments related to the 1996 acquisition of ZDI have been
reflected as of January 1, 1995 resulting in pro forma amortization, interest
and income tax provision adjustments. Such adjustments are further described
in note (a) to the table set forth below under "--Results of Operations." No
pro forma adjustments have been made related to the acquisition of SB COMDEX
as such adjustments are not material. Although such combination is not in
accordance with generally accepted accounting principles, management believes
the combined statements present the most meaningful basis of comparison.
Intercompany transactions for those periods were immaterial. The financial
information presented herein may not necessarily reflect the results of
operations which would have occurred had the Company been a stand-alone
entity.

- --------
(a) The acquisition of ZDI on February 29, 1996 gave rise to different bases
    of accounting for the period after the acquisition versus the period prior
    to the acquisition. This is primarily due to a purchase price which
    exceeded the book value of the assets acquired, financed by a higher level
    of both debt and equity as compared to the pre-acquisition capital
    structure. The amounts indicated above assume that the acquisition of ZDI
    took place on January 1, 1995; therefore, depreciation and amortization,
    interest expense and net loss have been increased (decreased) by
    approximately $6,386, $824 and $10,383, respectively, for 1996 and
    $38,312, $(3,484) and $46,759, respectively, for 1995.
(b) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. EBITDA is not intended to
    represent cash flows from operations and should not be considered as an
    alternative to net income as an indicator of the Company's operating
    performance or to cash flows as a measure of liquidity. The Company
    believes that EBITDA is a standard measure commonly reported and widely
    used by analysts, investors and other interested parties in the publishing
    and media industries.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED WITH THREE MONTHS ENDED MARCH 31,
1997 (UNAUDITED)
 
  For the first quarter of 1998, the Company will report revenue of $228.1
million compared to $224.9 million for the first quarter of 1997. Revenue from
publishing operations will decline approximately 4.1% primarily due to the
absence of $12.8 million of revenue from Macuser and MacWeek magazines, which
were transferred in October 1997 to a 50/50 joint venture with another
publishing company and are no longer consolidated in the Company's results.
The publishing segment will also report lower advertising revenue from its
business publications principally as a result of factors affecting the
computer technology industry generally, including slowing demand for computer
products, fewer new product launches, pricing pressures, vendor market share
shifts and excess PC inventories in distribution channels. This decline will
be largely offset by increased advertising sales in the Company's Internet
business and consumer publications. More than offsetting the decline in
publishing revenue will be an increase of 77% in revenue from the Company's
tradeshows and conferences operations, primarily the result of earlier
production of two events in the first quarter of 1998 that had been held in
the second quarter of 1997.
 
  The Company will report a loss from operations of $24 million for the first
quarter of 1998 as compared with a loss from operations of $15.6 million for
the first quarter of 1997. Reported EBITDA for the first quarter of 1998 will
be $15.1 million as compared to $25.5 million for the comparable period of
1997. The unfavorable variances are primarily due to the lower level of
advertising in business publications, which have higher profit margins than
consumer publications or the Internet business, coupled with approximately
$3.2 million of one-time costs for office relocations and $1.4 million of
expenses incurred in launching two new publications.
 
  As indicated below under "Seasonality," the first quarter accounted for
approximately 19.4% and 19.5% of the Company's revenue in 1996 on a pro forma
basis and 1997, respectively, and approximately 12.0% and 9.4% of the
Company's EBITDA for the respective years.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED WITH PRO FORMA YEAR ENDED DECEMBER 31,
1996
 
 Revenue
 
  Revenue increased by $73.2 million or 6.8% from $1,080.6 million in 1996 to
$1,153.8 million in 1997.
 
  Revenue from publishing grew by $50.5 million or 6.2% from $815.7 million to
$866.2 million. Approximately $22 million was due to inclusion of a full year
of results for the electronic gaming publications acquired in mid-1996 and two
publications launched in late 1996. Revenue from Internet services increased
$13.5 million or 71.9% due to higher advertising volume attributable to the
Company's growing presence on the Internet. Increases in advertising rates,
generally ranging between 3% and 10%, and a 5.1% increase in advertising pages
contributed $11.5 million. Revenue from international operations, which
generated 10.2% of the segment's revenue, decreased by $6.6 million due to the
strengthening of the U.S. dollar relative to the major European currencies.
Continued growth from new educational product launches and sales of market
research studies accounted for the balance of the revenue growth.
 
  Revenue from trade shows and conferences increased $22.6 million or 8.5%
from $264.9 million to $287.5 million. Approximately $15 million of the
increase was due to 11 new trade show launches, including revenue from
ancillary show-related sources. The balance of revenue growth was due to
higher exhibitor rates charged at the major events, partly offset by a decline
in revenue from COMDEX/Spring and certain U.K. events.
 
 Cost of production
 
  Production costs increased $22.6 million or 7.5% from $302.6 million to
$325.2 million.
 
  Publishing production costs increased $10.4 million or 4.8% from $215.3
million in 1996 to $225.7 million. Costs related to new launches and volume-
related growth increased approximately $20 million but were partly offset by
approximately $10 million of lower paper costs.
 
  The costs of producing trade shows and conferences increased $12.2 million
or 14.0% from $87.3 million to $99.5 million primarily as a result of costs
related to new events launched in 1997.
 
                                      33
<PAGE>
 
 Selling, general and administrative expenses
 
  Selling, general and administrative expenses increased $35.7 million or 6.8%
from $528.6 million to $564.3 million. The increase was due to the addition of
employees to support base business volume growth and launches of new products
and services. Results included a one-time $6.0 million charge for the
consolidation and restructuring of the trade shows and conferences business
which was announced in the fourth quarter of 1997.
Costs for the publishing segment rose 4.2% while those for the trade shows and
conferences segment rose 22.1% due to the number of new launches and the one-
time restructuring charge.
 
 Depreciation and amortization
 
  Total depreciation and amortization decreased $6.3 million to $154.9 million
in 1997. The reduction in depreciation and amortization expense was a result
of certain assets being fully depreciated in 1996.
 
 Interest expense, net
 
  Net interest expense increased $54.9 million or 40.5% to $190.4 million in
1997 due to interest on an additional $900 million of intercompany
indebtedness to Softbank incurred to finance a return of capital.
 
 Other non-operating income, net
 
  Other non-operating income/expense primarily reflects the Company's equity
share of earnings and losses from joint ventures and fees earned from
management of trade shows and conferences not produced by the Company. Income
increased $2.6 million from $6.1 million in 1996 to $8.7 million or 42.6%
reflecting growth in fees from managed events and reduced losses from joint
ventures.
 
 Income Taxes
 
  The 1997 combined income tax benefit of $1.3 million compares to a pro forma
income tax provision of $25.7 million in 1996. The improvement in the tax
provision is due to a higher pre-tax loss giving rise to a tax benefit. The
difference between the 1997 and 1996 effective tax rates and the federal
statutory tax rate of 35.0% is primarily due to non-recognition of tax losses
generated by the MAC Assets ($56.9 million and $77.2 million in 1997 and 1996,
respectively), non-deductible goodwill amortization ($10.2 million and $8.6
million, respectively) and state and local income taxes. In addition, the 1996
tax provision increased approximately $3.2 million as a result of pro forma
adjustments related to the ZDI acquisition.
 
 Net loss
 
  As a result of the charges described above, net loss for the period
increased $4.2 million or 6.2% from $67.0 million to $71.2 million.
 
 EBITDA
 
  EBITDA for 1997 was $272.9 million, an increase of $17.5 million or 6.8%
from the $255.4 million generated in 1996. The increase was due to higher
revenue and management fee income, net of higher production costs and selling,
general and administrative expenses. The ratio of EBITDA to revenue remained
relatively constant at 23.7% for 1997 compared to the 1996 margin of 23.6%.
Excluding the one-time charge related to the consolidation and restructuring
of the trade shows and conferences business, the 1997 ratio would have been
24.2%.
 
PRO FORMA YEAR ENDED DECEMBER 31, 1996 COMPARED WITH PRO FORMA YEAR ENDED
DECEMBER 31, 1995
 
 Revenue
 
  Revenue increased by $108.9 million or 11.2% from $971.7 million in 1995 to
$1,080.6 million in 1996.
 
  Revenue from publishing grew by $46.7 million or 6.1% from $769.0 million to
$815.7 million. Higher overall advertising rates combined with a 12.4% growth
in advertising pages contributed 47.5% of the revenue increase while the mid-
1996 acquisition of several electronic gaming publications accounted for 28.5%
of the
 
                                      34
<PAGE>
 
increase. New educational product launches and growth in sales of market
research studies accounted for the balance of revenue growth. Internet revenue
was slightly below the prior year due to the transition from a business based
on membership and subscription fees to one which is supported primarily by
advertising.
 
  Revenue from trade shows and conferences increased $62.2 million or 30.7%
from $202.7 million to $264.9 million. The launch of new international trade
shows accounted for 36.7% of the growth while the introduction of customized
events contributed 19.8%. The balance of the increase was due to growth in
exhibitor square footage and rates at the Company's major U.S. shows.
 
 Cost of production
 
  Production costs increased $40.2 million or 15.3% from $262.4 million to
$302.6 million.
 
  Publishing production costs increased $21.6 million or 11.2% from $193.7
million to $215.3 million, primarily due to volume-related growth and higher
paper costs. Approximately 31.5% of the increase was attributed to costs for
the magazines acquired mid-year while increased frequencies on certain
publications and a full year of costs for publications launched in late 1995
accounted for 18.1% of the increase.
 
  The costs of producing trade shows and conferences increased $18.6 million
or 27.0% from $68.8 million to $87.4 million. The increase was driven by the
cost of new product launches as well as higher direct marketing and facility-
related fees for the major U.S. events.
 
 Selling, general and administrative expenses
 
  Selling, general and administrative expenses rose $53.6 million or 11.3%
from $475.0 million to $528.6 million. This increase reflects the addition of
employees to support growth in the base business along with the launches of
new products and services. Costs for the publishing segment rose 5.8% while
those for the trade shows and conferences segment rose 61.6%, reflecting a
higher level of new launches and the absence of COMDEX related expenses for
the first three months of 1995 (COMDEX was acquired April 1, 1995).
 
 Depreciation and amortization
 
  Total depreciation and amortization of $161.3 million increased $7.1 million
from $154.2 million in 1995 primarily due to the inclusion of a full year's
depreciation and amortization relating to SB COMDEX, which was acquired April
1, 1995.
 
 Interest expense, net
 
  Net interest expense increased $2.4 million or 1.8% on a pro forma basis due
to higher average debt levels in 1996.
 
 Other non-operating income, net
 
  Income increased to $6.1 million compared to $.8 million in 1995 due to the
growth in fees from managed events along with reduced losses from joint
ventures.
 
 Income Taxes
 
  The combined income tax provision of $25.7 million compares to an income tax
provision of $9.6 million in 1995. The unfavorable variance in income taxes
and the difference in the 1996 and 1995 effective tax rates from the federal
statutory tax rate of 35% is primarily attributable to non-recognition of tax
losses generated by the MAC Assets ($77.2 million in 1996) and non-deductible
goodwill amortization ($8.6 million in 1996). In addition, the tax effects of
the 1996 and 1995 pro forma adjustments relating to the ZDI acquisition were a
$3.2 million and $11.9 million increase in tax provision, respectively.
 
 Net Loss
 
  As a result of the changes described above, net loss for the period
increased $5.2 million or 8.4% from $61.8 million to $67.0 million.
 
                                      35
<PAGE>
 
 EBITDA
 
  EBITDA for 1996 was $255.4 million, an increase of $20.3 million or 8.7%
from the $235.1 million generated in 1995. The increase was due to higher
revenue and management fee income, net of higher production costs and selling,
general and administrative expenses. The cost of new product launches caused
the growth rate of expenses to exceed the revenue growth rate and, as a
result, the ratio of EBITDA to revenue of 23.6% decreased slightly from 24.2%
for 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Historically, the financing requirements of the Company have been funded
through intercompany loans and advances.
 
  As a result of the Reorganization, the Company's intercompany debt owed to
Softbank will be reduced to $94.2 million. Such indebtedness bears interest at
9.9% and matures in February 2009. Concurrently with the Offering, the Company
intends to issue and sell approximately $400 million of Common Stock. In
addition, the Company will enter into the $1.35 billion Credit Facility, and
borrow $1.25 billion thereunder, to provide additional funds for the repayment
of intercompany debt to Softbank and to provide for the Company's working
capital requirements. It is expected that Softbank will apply a portion of the
amounts received by it in the Reorganization, among other things, to prepay
all amounts outstanding under a credit facility (under which the Company is a
guarantor) and terminate the commitments thereunder. See "Certain
Transactions--Certain Related Party Transactions."
 
  The Credit Facility will consist of a seven year $500 million reducing
revolving credit facility (with $400 million drawn at closing), a seven year
$450 million term loan and an eight year $400 million term loan. There will be
no scheduled reductions in the revolving credit commitment or amortization
under the term loan until September 2000. The Company has obtained a
commitment letter from The Bank of New York, Morgan Stanley Senior Funding,
DLJ Capital Funding and The Chase Manhattan Bank to provide such Credit
Facility. The consummation of each of the Offerings and the borrowings under
the Credit Facility are conditioned upon, and will occur simultaneously with,
the consummation of the others.
 
  Cash and cash equivalents were $30.3 million and $29.9 million at December
31, 1997 and 1996, respectively. The balance increased $.4 million due to the
factors discussed below:
 
  Cash (used) provided by operating activities was $(3.4) million and $65.7
million for the years ended December 31, 1997 and 1996, respectively. The
decrease from 1996 to 1997 was the result of higher interest expense and final
payment of long-term incentives to management established in connection with
the sale of ZDI in 1994.
 
  For the year ended December 31, 1997, the Company used $44.2 million in cash
for investing activities, principally $30.2 million in capital expenditures.
The majority of these expenditures were for computer equipment and leasehold
improvements. The Company believes that future capital expenditures associated
with new office space will be approximately $35 million in 1998 and $25
million in 1999 (net of tenant improvement credits). Cash used for investing
activities on a pro forma basis for 1996 was $66.8 million principally due to
capital expenditures of $22 million and the acquisition of Sendai Publishing
Group for $28 million.
 
  For the year ended December 31, 1997, the Company generated $47.9 million in
cash from financing activities, principally $66.6 million of capital
contributed by MAC to fund the operating losses of the MAC Assets, net of a
$21.4 million repayment of intercompany indebtedness. Pro forma cash flow from
financing activities for the year 1996 was $6.8 million, primarily from
capital contributions of $14.8 million from Softbank offset by a dividend of
$8.0 million.
 
  The Company believes that, based on its current level of operations and
anticipated growth, the Company's ability to generate cash, together with
other available sources of funds including available cash on hand at December
31, 1997, of $30.3 million, will be adequate over the next 12 months to make
required payments of principal and interest on the Company's indebtedness, to
fund anticipated capital expenditures and future working capital requirements.
However, actual capital requirements may change, particularly as a result of
any acquisitions the Company may pursue. The ability of the Company to meet
its debt service obligations and reduce its total debt will depend upon the
future performance of the Company.

  The Company has entered into a license and services agreement with MAC to
develop ZDTV. ZDTV is indirectly owned by MAC, but as part of this license and
services agreement MAC has granted the Company an option exercisable through
December 31, 1998 to purchase all of MAC's interest in ZDTV for an amount
equal to MAC's investment plus 10% per annum for the period of its investment.
Pursuant to the license and services agreement, the Company has agreed to fund
ZDTV's operations on behalf of MAC through unsecured advances which, for
approved levels of expenditure, are to be reimbursed by MAC. Such advances
bear interest at the 30-day LIBOR rate plus .50%. ZDTV's cash requirements are
expected to be approximately $54 million in 1998. The Company's cumulative
advances in respect of ZDTV, which totaled $14.4 million net of $10.1 million
in repayments through December 31, 1997, will be repaid concurrently with the
Reorganization. The Company has not yet determined whether it will exercise
its option to purchase MAC's interest in ZDTV. Any such purchase will depend
upon securing sufficient cable carriage, which may include entering into a
joint venture or other co-ownership arrangement, including an arrangement with
a third party cable system operator which will provide carriage and also
assume a portion of the ongoing cash requirements on terms that are acceptable
to the Company. ZDTV is not included in the Company's results of operations.
In the event that the Company acquires a controlling interest in ZDTV from
MAC, such acquisition would be accounted for as a pooling transaction; in the
event that the Company acquires a non-controlling interest, such acquisition
would be accounted for under the equity method. See "Certain Transactions."
 
SEASONALITY
 
  Historically, the Company's business has been seasonal as a significant
portion of the trade shows and conferences segment revenue has occurred in the
second and fourth quarters. In addition, the Company's publishing segment has
generated higher revenue in the second and fourth quarters. The following
table sets forth certain unaudited quarterly combined statements of operations
data for each of the eight quarters in the period ended December 31, 1997. In
the opinion of the Company's management, this unaudited information has been
prepared on a basis consistent with the audited Combined Financial Statements
of ZDI and ZDCF appearing elsewhere in this Prospectus (with the exception of
the March 31, 1996 data which has been prepared on the basis described in
Presentation of Financial Information above) and includes all adjustments
(consisting only of normal recurring adjustments) necessary to present fairly
the information set forth therein when read in conjunction with the Combined
Financial Statements and related notes thereto. The operating results for any
quarter are not necessarily indicative of results for any future period.

INFLATION AND CHANGES IN PAPER PRICES
 
  The Company continually assesses the impact of inflation and changes in
paper prices. The Company generally enters into contracts for the purchase of
paper which adjust the price on a quarterly basis. Paper prices began to rise
in 1994, rose significantly in 1995 and 1996 then decreased in 1997.
Management expects paper
 
                                      37
<PAGE>
 
prices to increase again in 1998. The Company will continue to monitor the
impact of inflation and paper prices and will consider these matters in
setting its pricing policies.
 
  The Company frequently reviews its purchasing and manufacturing processes
for opportunities to reduce costs and mitigate the impact of paper price and
postage rate increases (such as purchasing lighter-grade paper stock or, when
paper prices are at cyclical lows, increasing paper inventory or entering into
longer term contracts with suppliers). However, the Company has not entered,
and does not currently plan to enter, into long-term
forward price or option contracts for paper. See "Risk Factors--Risks
Associated with Fluctuations in Paper and Postage Costs" and "Business--Print
Publishing--Paper and Printing."
 
YEAR 2000 ISSUES
 
  The Company uses a number of computer software programs and operating
systems, including applications for its internal electronic communications
network and for various administrative and billing functions. The Company has
assessed the scope of the Company's risks related to problems these computer
systems may have in processing date information related to the year 2000 and
believes such risks are not significant.
 
  The Company has identified all of its significant internal software
applications which contain source codes that may be unable to appropriately
interpret the year 2000 and has already begun to modify or replace those
applications. The estimated costs to modify or replace these applications are
not material to the Company.
 
  In addition, the Company has inquired of its vendors and business partners
about their progress in identifying and addressing problems related to the
year 2000. All major vendors with whom the Company exchanges electronic
information or on whose internal software applications the Company may be
dependent have committed to the Company that plans are in place to be
compliant before processing of information related to calendar year 2000 would
be required. Although no assurance can be given that all of these third party
systems will be year 2000 compliant, the Company believes that risk is not
significant.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  SFAS No. 130, "Reporting Comprehensive Income," issued in June 1997, will
require the Company to disclose, in financial statement format, all non-owner
changes in equity. Such changes include, for example, cumulative foreign
currency translation adjustments, certain minimum pension liabilities and
unrealized gains and losses on securities available for sale. This statement
is effective for fiscal years beginning after December 15, 1997 and requires
presentation of prior period financial statements for comparability purposes.
 
  SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," issued in June 1997, establishes standards for reporting
information about operating segments in annual financial statements and
interim financial reports. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
Generally, financial information is required to be reported on the basis that
is used internally for evaluating segment performance and deciding how to
allocate resources to segments.
 
  SFAS No. 132, "Employer's Disclosure about Pensions and Other Postretirement
Benefits," is effective for the year ended December 31, 1998. This statement
revises the disclosure requirements for employers' pension and other retiree
benefits.
 
  The Company expects to adopt the above statements beginning with its 1998
financial statements.

                                   INDUSTRY
 
  Technology is widely recognized as one of the largest and fastest growing
sectors of the United States economy. The market for technology goods and
services is undergoing rapid expansion, largely fueled by: (i) increased
integration of computers into the workplace and home; (ii) shortened product
life cycles; and (iii) increased use of the Internet. The demand for computer
technology to enhance productivity as well as the increasing number of
applications in the areas of education, entertainment and communications has
dramatically increased the number of computers in use. The number of personal
computers in use worldwide has doubled from 150 million in 1995 to over 300
million in 1997, significantly broadening the consumer and business markets
for computer technology. In addition, rapid technological advances have
shortened product life cycles; for example, the estimated marketable product
life of a PC has decreased from five years in 1981 to less than six months
today. The Internet has also become a widely accepted information tool as
demonstrated by the proliferation of users, with 68 million adults in the U.S.
having used the Internet by year-end 1997, up from just five million in 1994,
and the sharp increase in the number of commercial Web sites worldwide, from
30,000 in 1995 to approximately 400,000 in 1997.
 
  For buyers and users of computer technology products, these factors have
increased the demand for objective, up-to-date information and analysis. For
sellers of such products, these factors have increased their need to
communicate a wide range of information regarding their products and services,
from advertising designed to increase sales to education designed to improve
end-user satisfaction and build brand loyalty. Computer technology-focused
media enable sellers to communicate their message effectively by targeting a
focused customer base. As a result of the broadening of the consumer base, as
well as the favorable demographics of this base, computer technology
publications and other media are becoming increasingly attractive as a
platform for consumer product advertising.
 
COMPUTER TECHNOLOGY PRINT PUBLICATIONS MARKET
 
  In 1996, advertising revenue in computer-oriented print publications
totalled $1.3 billion. In 1997, advertising revenue in computer-oriented
publications grew by 11.2% while the advertising market as a whole grew by
8.3% in the first ten months (the latest period for which data is available)
as compared to the same period in the prior year. Growth in advertising and
circulation revenue for computer-oriented publications has outpaced the
publishing industry in general, growing 10.4% a year from 1994 to 1997, versus
6.3% a year for all periodicals.
 
COMPUTER TECHNOLOGY TRADE SHOWS
 
  A trade show can be described as a face-to-face version of a print
publication. Trade show attendees, like readers of print publications, are
presented with product advertisements in the form of exhibits and "editorial"
content in the form of conferences and other ancillary forums. Producers of
trade shows and conferences generate revenue from exhibit space sales,
advertising and conference and general attendance fees. Trade shows and
conferences allow sellers to conduct a large volume of face-to-face sales
presentations to qualified buyers in a short period of time. Professional
attendees include hardware and software manufacturers and developers, sales
and distribution personnel and large volume end-users. Industry leaders such
as Microsoft Corporation, Intel Corporation and Cisco Systems, Inc. have
consistently used these events to promote the launch of important products in
order to reach top-ranking decision-makers in the computer technology
industry.
 
  Trade shows are becoming an increasingly important part of the marketing
strategy for information technology vendors. A recent study noted that
companies consider trade shows one of the most effective mediums for
generating and closing sales, second only to direct selling. Exhibit space
revenues from North American computer-product trade shows were approximately
$573 million in 1997. In 1997, exhibit square footage rose 28% at such shows,
the number of exhibiting firms increased 20% and attendance rose 28%.

ONLINE AND OTHER TECHNOLOGY INFORMATION SERVICES
 
  The proliferation of Web sites and the growing number of users combine to
make the Internet an increasingly significant advertising and brand-building
vehicle. The Internet enables marketers to deliver targeted messages as a
result of the ability to track consumer behavior and immediately convert
advertising responses into commercial transactions. The advertising-based
business model for online services, which is similar to print and television
media, involves the payment to Internet content and service providers of
advertising fees based primarily on the demographics and purchasing habits of
the audience and on the number and positioning of advertisements delivered.
The market for advertising on the Internet was approximately $597 million in
1997, a 152.6% increase from 1996. The computer technology industry has been
one of the leading advertisers on the Internet, comprising 35% of all
advertising dollars for the twelve months ended September 30, 1997. Web sites
focused on computing content provide yet another forum for sellers of computer
technology to deliver targeted product information and advertising to a
premium customer base. The Company expects that the Internet market, like the
publications market, will continue to broaden and gain appeal as a platform
for consumer product advertising as well.

                                   BUSINESS
 
  The Company believes it is the world's preeminent integrated media and
marketing company focused on computing and Internet-related technology, with
principal platforms in print publishing, trade shows and conferences, online
content, market research and education. The Company provides global technology
companies with marketing strategies for reaching key decision-makers. The
Company is the successor to Ziff-Davis Publishing Company, which pioneered the
development of special-interest magazines; Ziff-Davis Exposition and
Conference Company; and the COMDEX computer and network-related trade show
operations of Interface Group-Nevada, Inc.
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the
top three computer magazines in the U.S. and are among the top 25 U.S.
magazines, each as measured by total revenue in 1996 (the latest year for
which data is available). The Company also produces the world's most important
trade shows serving vendors, resellers, buyers and users of computer
technology, including COMDEX/Fall, the largest trade show in the U.S. in 1997.
The Company's ZDNet.com Web site is the leading computing content site and
ranked the number one Web site in 1997 in the category of news, information
and entertainment, as measured by visitors per month.
 
  The Company's 28 primary U.S. and international titles, including its joint
ventures, and over 50 licensed publications, total more than 80 publications
distributed worldwide, with a combined circulation of over eight million
primary readers. In 1997, Ziff-Davis was the largest technology publisher in
the U.S. in terms of total magazine revenue. In that same year, Ziff-Davis
accounted for 36.8% of all advertising and circulation dollars spent in
computer periodicals, with at least 50% more total magazine revenue than its
closest competitor. The Company's publications include PC Magazine, the
largest circulation computer magazine in the world, Computer Shopper, the
leading magazine targeted at direct buyers of computers (along with its Web-
based companion, Netbuyer), Computer Life, a monthly magazine for home
computing enthusiasts, and Family PC, a magazine specifically targeted to
households with children. ZD Labs, its computer testing facility, enables the
Company to provide reliable and authoritative product evaluations to a
sophisticated audience of brand-specifiers and decision-makers in both the
business and consumer markets. The preeminence of the Company's publications
among readers and advertisers is based on its comprehensive market and product
coverage, the quality of its editorial content and the influence of its
readership.
 
  In 1997, the Company produced over 50 trade shows and conferences worldwide
with over two million estimated attendees. The Company's COMDEX/Fall event is
the number one ranked trade show for all industries in the U.S. as measured by
total revenue, total exhibit space and number of attendees.
 
  The Company's other media and marketing platforms include online content,
market research, education and the publication of computer-related newsletters
and training manuals. In addition, the Company and MAC have developed ZDTV,
the first 24-hour cable television channel and integrated Web site focused
exclusively on computers, technology and the Internet, which is expected to be
launched in the first half of 1998. The Company has an option to purchase ZDTV
from MAC on or before December 31, 1998. See "--Television."
 
  The Company developed certain international consumer and Internet
publications, international trade shows and the ZDNet business under the
ownership of MAC. As a result of the Reorganization, these businesses have
been or will be purchased from MAC. See "The Reorganization."
 
  The Company's Ziff-Davis Media Network integrates the Company's marketing
activities into one cohesive resource for its largest customers. Originally
established to provide discounts for advertisers buying across two or more
magazine titles, the Media Network has been expanded to allow marketers to
reach their various target buyers through any combination of the Company's
media and marketing platforms.
 
  The Company had total revenue of $1.154 billion for 1997. The Company's
revenue is primarily derived from advertising sales, which represented 51.9%
of total revenue in 1997. The second largest component of the
 
                                      41
<PAGE>
 
Company's revenue is derived from trade shows and conferences, which accounted
for 23.5% of total revenue in 1997. Circulation revenue, comprised of
subscription and newsstand single copy sales, generated 13.1% of the Company's
revenue in 1997 and other revenue components, including online content, market
research and revenue derived from joint ventures and licenses, contributed
11.5% in 1997.
 
BUSINESS AND OPERATING STRATEGY
 
  The Company's objective is to be the preferred marketing partner to
technology vendors and service providers seeking to reach primary decision-
makers involved in the specification and purchase of their products and
services. Major elements of the Company's strategy include:
 
  Maintain Focus on the Computer and Internet Technology Markets. The Company
believes that its singular focus on the computer and Internet-related
technology markets provides it with substantial growth opportunities as well
as the ability to broaden its expertise in attracting both audiences and
advertisers.
 
  Develop the Most Comprehensive, Objective and Authoritative Content. The
Company strives to produce the most comprehensive, objective and authoritative
editorial content in order to attract category brand-specifiers and decision-
makers to its media platforms. The ability to provide focused audiences with
their specific information needs attracts the leading advertisers and
exhibitors to the Company's products and services.
 
  Build Upon Brand Strength of Existing Media Properties. The Company will
pursue continued growth from its core portfolio of leading brands, such as PC
Magazine, PC Week, COMDEX and ZDNet, by seeking to expand its market share of
audiences and advertisers and enhancing the quality and accessibility of the
content it produces and marketing services it provides. In addition, the
Company will continue to extend its existing brands into other platforms to
offer multiple media presentations of its content.
 
  Continue to Leverage Multiple Media Marketing Platforms. The Company
believes that the scope and depth of its products and services across multiple
media platforms and geographic territories creates growth opportunities
exceeding those that such businesses could achieve independently. Such
opportunities include the leveraging of strong relationships with accounts in
one media platform into other platforms, cross-marketing Ziff-Davis products
and services to the audiences of its different platforms and packaging
integrated marketing products across all platforms for large advertisers. The
Company believes that its ability to offer clients multiple platform marketing
solutions gives it a competitive advantage over single platform providers.
 
  Expand Leadership on the Internet. The Company intends to use its already
significant presence on the Internet and broad experience in publishing to
continue to reach new audiences and increase advertising revenue. In addition,
the Company believes that the large existing audience for ZDNet and its
affiliated sites, together with its publishing experience, gives it a
competitive advantage in identifying, acquiring and developing new products
and services.
 
  Launch New Products and Services. The Company believes that rapid advances
in technology create additional growth opportunities for the launch of new
products and the expansion of its audiences and advertising base. The Company
seeks to be the first to identify new audiences and develop products and
services which respond to their informational needs. Management believes that
the scope of its operations and its experience in launching new products
across multiple media platforms and geographic regions reduce the risks
typically associated with these activities and enable it to more readily
achieve market acceptance for new products and services as compared to other
media companies.
 
  Expand Global Reach. The Company intends to leverage its widely recognized
brands and its experience in multinational operations to expand further into
key overseas markets, focusing on those markets which have size and growth
characteristics that will support its strategy of cross-media operations.
Management intends to further expand internationally through the launch
overseas of proven U.S. properties, joint ventures and licensing arrangements
with local operating partners and through selective acquisitions.

  The Company expects to fund its business and operating strategy from
internally generated cash flow from operations, which are estimated to be
sufficient to fund investments as well as the repayment of indebtedness. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
PRINT PUBLISHING
 
  The Company is a leading computer-related magazine publisher, with 28
primary U.S. and international titles, including its joint ventures, and over
50 licensed publications, totaling more than 80 publications distributed
worldwide. In 1997, the Company's publications had combined circulation of
over eight million primary readers worldwide. Approximately 62% of the
Company's total revenue in 1997 was attributable to its print publishing
business. Each of the Company's magazines is designed to appeal to a target
audience of sophisticated customers in the business and consumer markets by
providing high-quality editorial content, often supported by independent
laboratory-based product testing. The Company seeks to maintain and increase
its revenue by introducing current advertisers to new titles, by attracting
new advertisers targeted at the Company's readership and by developing new
reader and advertising categories. Each of the Company's primary publications
has established its own Web site as a complementary delivery platform.
 
  The Company believes its preeminent position in the computer publishing
market is based upon its leading brands in key categories, its ability to
successfully develop new brands for emerging product categories, its strength
in circulation and its ability to expand internationally. Ziff-Davis seeks to
produce the highest quality editorial content; it employs top editors and
columnists supported by laboratory-testing facilities that produce widely
acknowledged authoritative benchmarks for determining product quality. See "--
Editorial, Laboratory Testing and Benchmark Software." In addition to its
leading publications targeted at brand-specifiers and other industry
professionals, the Company has successfully introduced new publications
targeted at emerging sectors, including the consumer market (Family PC,
Computer Life and Computer Gaming World), technology lifestyle (Yahoo!
Internet Life) and Internet professionals (Internet Computing and Inter@ctive
Week). The Company's newsstand strategy focuses on developing strong
relationships with a key distributor and large retail accounts. In order to
offer clients coverage of broad international markets, the Company has adopted
a licensing strategy designed to maximize global reach and maintain content
quality in international publications while reducing cost of entry into new
markets. Depending on the characteristics of a particular market, the Company
may choose to own an international publication, enter into a master license
covering one or more titles, or enter into a joint venture if an attractive
local partner can be identified.
 
  The Company's PC Magazine, PC Week and Computer Shopper magazines are the
top three computer magazines in the U.S. and are among the top 25 U.S.
magazines, each as measured by total revenue in 1996 (the latest year for
which data is available). In 1997, Ziff-Davis was the largest technology
publisher in the U.S. in terms of total magazine revenue. In that same year,
Ziff-Davis accounted for 36.8% of all advertising and circulation dollars
spent in computer periodicals, with at least 50% more total magazine revenue
than its closest competitor. In recent years, advertisements in the Company's
publications have expanded beyond those for computer technology products to
include consumer product advertising, reflecting the desirable demographics of
the Company's readership, as well as the expanding readership of computer
technology publications to a broader consumer market.
 
  The Company's publications include paid-circulation magazines, which
generate revenue from newsstand sales, subscriptions and advertising, and
controlled-circulation publications, which are distributed free of charge to
qualified information technology professionals and generate revenue
principally from the sale of advertising. In addition, the readership of
controlled-circulation publications provides valuable demographic information
to the Company. Most of the current Ziff-Davis publications are either monthly
magazines providing comparative, laboratory-based product reviews or news
weeklies providing product and industry news and analysis; however, the
Company also serves the developing market for lifestyle and entertainment
publications focusing on technology.

  The Company's U.S. publications have a total circulation of over six million
primary readers, and the Company had a worldwide circulation of over eight
million primary readers. Its six paid-circulation business magazines
(including one joint venture) accounted for 47.2% of the total paid-
circulation of all computer technology business magazines in the U.S. in 1997.
In 1997, PC Magazine's circulation was greater than that of Business Week,
Fortune or Forbes. With respect to newsstand sales, a critical measure of
magazine vitality, in the first six months of 1997 Ziff-Davis accounted for
47.5% of all computer magazine copies sold, and on average Computer Shopper
had greater newsstand sales than Business Week, Fortune and Forbes combined.

 ZIFF-DAVIS MEDIA NETWORK
 
  The Company's Ziff-Davis Media Network integrates the Company's marketing
activities into one cohesive resource for its largest customers. Originally
established to provide discounts for advertisers buying across two or more
magazine titles, the Media Network has been expanded to allow marketers to
reach their various target buyers through any combination of the Company's
media and marketing platforms. Currently 21 professionals in the Ziff-Davis
Media Network link major advertisers from one platform into other platforms.
 
 EDITORIAL, LABORATORY TESTING AND BENCHMARK SOFTWARE
 
  The Company has invested heavily in its editorial staff and in training and
technology to develop the high level of technical expertise required to
provide quality content on computer technology. It employs over 450 editorial
personnel worldwide, including award-winning editors and experts in their
fields. The Company believes that it provides its consumers with the most
reliable, objective and focused product evaluations and industry news. Because
of the quality and reputation of Ziff-Davis laboratory tests, the Company's
publications are widely regarded as a reliable source of objective product
evaluations. The Company's influence over computer purchasing carries with it
the responsibility to maintain the highest standards of fairness and
objectivity in its product reviews. To ensure this impartiality, Ziff-Davis
has instituted policies governing separation of editorial functions from
advertising sales functions and restricting trading in securities of
technology-related companies by its journalists.
 
  The Company is committed to laboratory-based product testing as an integral
part of its editorial mission. In 1997, the Company spent over $10 million in
laboratory testing. Testers from many of the Company's different publications
work with the ZD Labs staff to provide comprehensive, objective test results
that can assist readers and users of Ziff-Davis publications and other
content-based services in making buying decisions. In addition to the core ZD
Labs staff, Ziff-Davis publications such as PC Magazine, PC Week, Computer
Shopper and PC Computing maintain their own staff and/or testing space at ZD
Labs as well as at their own locations. The ZD Labs testing facility provides
space for testing hundreds of products and systems. One of its newest
facilities is an Internet/Intranet lab dedicated to testing Web servers and
other Internet products. In its domestic lab facilities, the Company employs
120 technicians, enabling it to test thousands of products each year and
conduct large-scale tests that effectively simulate corporate installations.
The Company believes ZD Labs gives it a competitive advantage in terms of
staffing, equipment and access to the technology necessary to evaluate
products.
 
  ZD Labs produces the core, publicly available and widely distributed
benchmark software that Ziff-Davis publications use worldwide to measure the
performance of PCs, Macintosh systems and servers. The Company's benchmarks
have become industry standards among major buyers of computer and Internet-
related technology.
 
 SOURCES OF PRINT PUBLISHING REVENUE
 
  Advertising Sales. The Company's advertising strategy for its publishing
business is based on helping customers maximize the return on their
advertising investment. Advertising sales accounted for 78.4% of the Company's
total print publishing revenue for 1997. Ziff-Davis has historically invested
in comprehensive research to better understand the computer technology market
and the positions of its different publications. The Ziff-Davis sales
philosophy is to encourage its sales force to adopt the role of marketing
consultant, using Ziff-Davis market research tools, such as the Company's
InternetTrack and BrandTrack services, to provide clients with information on
overall industry trends as opposed to more limited sales presentations
focusing on individual publications. As of December 31, 1997, Ziff-Davis
employed over 250 salespeople, sales managers and sales executives and over
325 sales support staff in its publishing segment to provide customer service,
research, promotional support and value-added programs for advertisers.
 
  Circulation. Ziff-Davis maintains centralized circulation operations which
enable the Company to capitalize on its successful strategies and practices
across all publications on a timely basis. The Company strives
 
                                      46
<PAGE>
 
to increase its readership by building relationships with distributors,
retailers and subscribers. Revenue from circulation of the Company's paid-
circulation magazines accounted for 18.4% of the Company's total print
publishing revenue in 1997. This was comprised of subscription sales (10.1% of
total revenue in 1997 and 10.5% in 1996) and newsstand sales (8.1% in each of
1997 and 1996). The Company's publications have a total circulation of over
eight million primary readers worldwide.
 
  The Company's newsstand strategy focuses on developing strong relationships
with a key distributor and large retail accounts. Ziff-Davis recently entered
into a newsstand distribution arrangement in the U.S. with Warner Publishers
Services ("Warner"), a division of Time Warner Inc., which covers the
Company's entire line of paid-circulation magazines. As of January 1998, the
Company became Warner's principal supplier of computer technology
publications. In addition, the Company has preferred distribution arrangements
with large retailers including WalMart, Barnes & Noble, Staples and Office
Max. These arrangements include special magazine displays featuring Ziff-Davis
brand products which increase the prominence of the Company's publications and
strengthen its brand identity. With respect to newsstand sales, a critical
measure of magazine vitality, Ziff-Davis publications accounted for 47.5% of
all computer magazine copies sold in the first six months of 1997.
 
  The Company's subscription strategy is to maintain a highly focused
readership in order to provide the most effective affinity between advertisers
and readers. The Company believes that this strategy increases subscriber
loyalty and renewal rates and allows the Company to provide advertisers with
access to a precisely focused target audience. The Company's six paid-
circulation business magazines (including one joint venture) accounted for
47.2% of the total paid circulation of all computer technology business
magazines in the U.S. in 1996.
 
  Licensing and Joint Ventures. The Company has adopted a licensing strategy
designed to maximize global reach and maintain content quality in
international publications while reducing the cost of entry into new markets.
In markets where the Company believes that the opportunity is significant
relative to the cost of entry, the Company may operate through wholly-owned
publishing companies. Through subsidiaries, the Company currently has
publishing operations in France, the United Kingdom and Germany. In other
markets, the Company has opted to enter into licensing arrangements with local
publishing companies, and currently has over 50 licensed publications
worldwide. The Company's licenses are generally three to five year agreements
that provide for a minimum annual royalty against a percentage of revenue. The
Company also operates through a number of joint venture companies with
partners, including joint ventures with International Data Group, Inc. ("IDG")
and an affiliate of The Walt Disney Company ("Disney") in the U.S. and a
venture with Richina Media Holdings and other local agencies in China. The
Company is currently negotiating with an affiliate of Disney to buy its
interest in the Family PC joint venture.
 
 U.S. PUBLICATIONS
 
  Business Magazines. In the U.S. market, the Company publishes ten computer
publications directed to business buyers, including six paid-circulation

market segment. Two of these titles, Macworld and MacWeek, are dedicated to
the Apple Macintosh market and are published by Mac Publishing L.L.C., a joint
venture between the Company and IDG.
 
    PC Magazine provides corporate buyers of computer technology with
  comprehensive laboratory-based comparative reviews of PC hardware, software
  and networking products, with a focus on technical specifications. With a
  paid circulation of more than 1.18 million, PC Magazine is the largest
  circulation computer magazine in the world, accounting for 35.4% of all
  computer advertising revenue in directly competitive U.S. publications in
  1997. PC Magazine has expanded its editorial material into other media,
  including a Web publication, PC Magazine Online, and a CD ROM-based
  multimedia companion magazine, PC Magazine Extra, which has a paid
  circulation of over 75,000. PC Magazine also produces two newsstand-only
  specials: Your New PC, which supplies buying advice for less sophisticated
  computer buyers, and InternetUser, which focuses on reviews of Internet
  products.

three year agreements, with quarterly pricing adjustments, and are renewable
on a staggered basis. Most agreements contain pricing clauses that seek to
ensure the most competitive pricing on a quarter to quarter basis. The
Company's main paper suppliers for its U.S. publications are Bowater,
Champion, Consolidated, Fraser and UPM, which provided 12%, 33%, 15%, 12% and
12%, respectively, of the Company's paper supply in 1997 as measured by
tonnage. Printing companies that the Company has relationships with include
R.R. Donnelley, Brown, Quadgraphics and Quebecor. Approximately 50% of the

Donnelley, which has a number of alternative printing sites. Printing

TRADE SHOWS AND CONFERENCES
 
  The Company is the leading producer of trade shows, conferences and
customized marketing and educational programs for the computer industry in the
U.S. Approximately 25% of the Company's total revenue in 1997 was attributable
to its trade show and conference business which includes the industry-wide
COMDEX events, other trade shows and conferences focused on specific segments
of the computer technology industry, and customized events designed to meet
the marketing needs of specific clients. In 1997, the Company produced over 50
trade shows and conferences, 18 of which were held in North America.
 
  The COMDEX/Fall event has been held for 18 years and is the number one
ranked trade show for all industries in the U.S. as measured by total revenue,
total exhibit space and number of attendees. In 1997, the Company estimates
that over two million people attended Company trade shows and conferences
worldwide. In addition to COMDEX/Fall, held annually in Las Vegas, the Company

computer industry, while the Seybold Seminars focus on publishing and graphic
communications. In addition, the Company will produce the following segment-
focused trade shows in 1998: (i) WINDOWS WORLD in conjunction with Microsoft
Corporation; (ii) EXPO COMM, servicing the worldwide telecommunications
industry; (iii) CommUnity, for the emerging corporate integrated data, voice
and video segments; (iv) COMDEX/Enterprise, focusing on solutions for the
large corporate information technology infrastructures; (v) Java Internet
Business Expo, sponsored by Sun Microsystems, Inc. and focusing on the full
range of Java technology for information technology professionals; (vi)
Service and Support Expo, focusing on technology for help desk and information
technology support services; and (vii) Learning Technology, focusing on
applying technology to education and training. The Company's customized
conferences are designed to meet the marketing needs of a specific client. For
example, the Company produced the Java One series of conferences for Sun
Microsystems, Inc. which were designed to introduce Java software to the
developer community.
 
  Attendees at the Company's trade shows and conferences cover a wide range of
participants from the computer industry, including manufacturers,
distributors, dealers, retailers, value-added and other resellers and large
corporate end-users. Each event includes an extensive conference program,
which provides a forum for the exchange and dissemination of information
germane to the particular event's focus. In addition, each event has one or
more "keynote" sessions with speakers drawn from computer industry leaders.
The Company estimates that in 1997 over 5,000 companies participated as
exhibitors in its trade shows and conferences and over 8,000 industry experts,
analysts and consultants spoke at its conference programs.

 SOURCES OF TRADE SHOW AND CONFERENCE REVENUE
 
  In 1997, exhibitor space fees accounted for 64.8% of the Company's total
trade show and conference revenue. The Company believes most trade show
producers receive virtually all of their revenue from the sale of exhibitor
space fees. The Company has actively sought to increase its revenue from other
sources, including attendee fees, which accounted for 35.2% of all trade show
and conference revenue in 1997.
 
  At each trade show, all exhibitors pay the same price per square foot of
booth space, regardless of the exhibit hall they select or the location or
size of their booth within a given hall. Typically, a majority of each trade
show's exhibitors commit to booth space during that year's show for the next
year's show. The Company encourages this commitment through a booth selection
procedure that grants priority based upon a seniority system. Annual renewal
is required for exhibitors to maintain their seniority. Exhibitors pay for
space in two or three installments, the last of which is usually due six
months prior to the upcoming event.
 
                                      51
<PAGE>
 
  In 1997, attendee fees accounted for 14.9% of the Company's trade show and
conference revenue, primarily from N+I and Seybold events. Most COMDEX
attendees come as the invited guests of exhibiting companies. The Company
provides exhibiting companies with a supply of complimentary admission
tickets, which are generally given to customers and key prospects. This helps
exhibitors ensure that their best customers and prospects will attend.
 
  The Company's trade show and conference advertising revenue is derived
principally from five products: (i) a daily newspaper distributed during the
show; (ii) the Program Exhibits Guide; (iii) the Preview, a newspaper
published and distributed to pre-registrants and certain prior year attendees
in advance of the show; (iv) advertising billboards and banners; and (v)
ancillary exhibitor logo products which are sold to exhibitors to increase
booth traffic and name recognition.
 
  The Company also maintains a continuously updated database containing the
names and certain demographic information on its over two million attendees.
This database is rented to direct mail users on a fee-per-use basis.
 
 COMDEX
 
  COMDEX trade shows cover a broad range of new technologies at every stage in
their development and evolution--from introduction to commercial maturity.
Many of the most significant computer product launches over the past 18 years
occurred at COMDEX, including the launch of the IBM PC, Lotus 1-2-3, Windows
3.1 and DVD.
 
  COMDEX/Fall is a five-day trade show held annually in November in Las Vegas.
In 1997 COMDEX/Fall had over 1,750 exhibiting companies occupying more than
1,350,000 net square feet of exhibit space and more than 200,000 attendees.
COMDEX/Spring, which was launched in 1981, is a smaller version of the fall
event. In 1997, it was held in Atlanta and had more than 600 exhibiting
companies and over 100,000 attendees. In April 1998, COMDEX/Spring will be
held in Chicago. For the last six years, the Company, in cooperation with
Microsoft Corporation, has produced a WINDOWS WORLD trade show concurrently
with COMDEX/Spring.
 
  In 1993, the Company began launching additional COMDEX events in order to
capitalize on the international recognition of the COMDEX brand name. The 1998
schedule includes other COMDEX events in Miami, Toronto, Vancouver, Montreal,
Mexico City, Monterrey (Mexico), Buenos Aires, Sao Paulo, Rio de Janeiro,
London, Paris, Tokyo, Seoul, New Delhi, Beijing, Singapore and Cairo.
 
 NETWORLD + INTEROP
 
  N+I is the largest of the Company's segment-focused trade shows and is the
leading show for professionals in the rapidly growing field of computer
networking. N+I places strong emphasis on the quality of its conference
programs and, in recent years, has become a leading educational forum for the
Internet and enterprise computing communities. The largest N+I event is held
annually in Las Vegas in May. Each N+I trade show features InteropNet, a live,
multi-platform network that interconnects exhibitors to one another and to the
Internet. In 1997, the N+I Las Vegas event had over 600 exhibiting companies
occupying more than 400,000 net square feet of exhibit space and more than
55,000 attendees. The N+I Atlanta event, held in October each year, is only
slightly smaller in all categories. The 1998 schedule of N+I events includes
seven shows in six countries.
 
 SEYBOLD SEMINARS
 
  The Company's Seybold Seminars are segment-focused trade shows and are a
leading information and education provider for traditional and new media
publishing industries. These shows focus on the latest technologies and
products, design tools and desktop applications. The largest of the Seybold
series is held annually each September in San Francisco. In 1997, this Seybold
show had over 300 exhibiting companies occupying more than 140,000 net square
feet of exhibit space and more than 38,000 attendees. Other Seybold events are
held in New York and Tokyo.

 OTHER EVENTS
 
  The Company also produces EXPO COMM, a series of worldwide trade shows
focusing on the telecommunications, wireless and telephony segments of the
information technology marketplace. The Company purchased a 50% interest in
the series from EXPO COMM's founder, E.J. Krause & Associates, Inc., in 1996.
EXPO COMM events are held in Chicago, Moscow, Beijing, Buenos Aires, Sao
Paulo, Mexico City, Monterrey (Mexico) and Tokyo. WINDOWS WORLD trade shows
are held in cooperation with Microsoft Corporation concurrently with the
Company's COMDEX events in Chicago, Mexico City and Toronto. These events
showcase the latest Windows-based applications and solutions.
 
  The Company also produces Learning Technology trade shows for professionals
focused on learning and helping others to learn to use technology, held in
Atlanta and Los Angeles, and Object World trade shows focused on the
commercial and practical aspects of applying object technology and distributed
computing in today's business environment, held in San Francisco, Boston,
London, Frankfurt and Tokyo.
 
INTERNET
 
  The Company maintains a number of Web sites related to its publications,
trade shows and conferences and other media platforms. The Company's ZDNet.com
Web site is the leading computing content site and the number one Web site in
the category of news, information and entertainment, in each case as measured
by visitors per month in 1997, ranking it higher than Web sites produced by
Time Warner Inc. (Pathfinder.com), Disney (Disney.com) and ESPN
(Sportzone.com). The Company estimates that the ZDNet Web site serves more
than 100 million pages each month to more than five million visitors. It has
over one million registered users and over 2.5 million e-mail recipients per
month. ZDNet has successfully attracted new audiences in addition to
established computer enthusiasts, as is evidenced by the fact that 64% of
ZDNet users do not regularly read any computer technology publications. ZDNet
seeks to be the most comprehensive site for quality content about computing.
 
  ZDNet has its own staff of over 100 editors, designers and technology
experts who create and develop a wide range of content, including current and
in-depth news, product reviews, investor information, shareware library,
online shopping, training, forums and chat areas. ZDNet coordinates and
collaborates on content development with the Company's other publications and
businesses and is fully integrated with the Company's individual Web sites.
ZDNet includes Netbuyer, a leading Web site devoted to computer retailing.
Softbank is a majority owner of Gamespot, a leading Web site for gaming
information, including reviews, demo downloads and other content. Softbank's
interest in Gamespot will be contributed to the Company concurrently with the
Reorganization. Over 80% of the content on ZDNet is original, with the
remainder supplied by the Company's print publications.
 
  The Company has a number of arrangements with leading Web sites and product
manufacturers to increase traffic and thereby advertising revenue to ZDNet.
ZDNet is the preferred computer and technology content-provider for leading
Internet sites and products, including Yahoo!, Excite, MSNBC and Pointcast, as
well as for leading Internet service providers such as Mindspring and AT&T's
World Net, each of which provides a direct link to ZDNet. ZDNet also has
arrangements with original equipment manufacturers, such as Compaq Computer
Corp. and Gateway 2000, Inc., whereby ZDNet is an automatic bookmark in the
Web browsers included on such computers.
 
  The Company distributes localized versions of ZDNet in Germany as ZDNet
Deutschland, in France as ZDNet France and in the United Kingdom as ZDNet UK.
Localized versions of ZDNet are also distributed by licensees in Italy,
Russia, Japan, China, Taiwan, Australia and Latin America.
 
TELEVISION
 
  In order to expand its media platforms, the Company has entered into a
license and services agreement with MAC to develop ZDTV, which is expected to
be launched in the first half of 1998. ZDTV will be the first 24-hour cable
television channel and integrated Web site focused exclusively on computers,
technology and the Internet. ZDTV will target a wide range of viewers,
including computer and technology enthusiasts, computer gaming enthusiasts,
business people, teens, families and other viewers with a sustained interest
in computers, technology
 
                                      53
<PAGE>
 
and the Internet. Programs are expected to include educational features,
product evaluations, gaming tips and strategies, current events and other
entertainment. ZDTV will also feature live interactive programming allowing
viewers to participate through simultaneous Web programming on ZDTV.com.
 
  ZDTV is indirectly owned by MAC, but as part of the license and services
agreement, MAC has granted the Company an option exercisable through December
31, 1998 to purchase all of MAC's interest in ZDTV for an amount equal to
MAC's investment plus 10.0% per annum for the period of its investment.
Pursuant to the license and services agreement, the Company has agreed to fund
ZDTV's operations on behalf of MAC through unsecured advances which, for
approved levels of expenditure, are to be reimbursed by MAC.  Such advances
bear interest at the 30-day LIBOR rate plus .50%. ZDTV's cash requirements are
expected to be approximately $54 million in 1998. The Company's cumulative
advances in respect of ZDTV, which totaled approximately $14.4 million net of
$10.1 million in repayments through December 31, 1997, will be repaid
concurrently with the Reorganization. The Company has not yet determined
whether it will exercise its option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon access to sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Company. ZDTV is not included in the
Company's results of operations. See "Certain Transactions."
 
  ZD Television Productions, which is also indirectly owned by MAC, creates
customized programming for ZDTV and third parties. The Company's option to
purchase ZDTV from MAC also includes the option to purchase ZD Television
Productions. Its productions have included the regional Emmy award-winning
"The Site" with MSNBC and "21st Century Home" with Home & Garden Television.
See "Certain Transactions."
 
EDUCATION
 
  The Company is an independent publisher of computer training products and
services for end-users and advanced technology professionals. Its products and
services include Internet-based training, computer-based training, instructor-
led courseware and customization tools. The Company believes that its
education offerings extend the Company's reach and brand reputation while
permitting the Company to attract and retain customers.
 
  The Company is a source of software-specific newsletters and technology
information, with more than 50 titles, a family of CD-ROM products and an
interactive Web site. Generally published monthly, the titles include time-
saving tips and techniques on products such as Windows 95, Novel NetWare,
Visual Basic, Word, Excel, Microsoft Office, PhotoShop and Windows NT, in
addition to several programming and operating systems journals. The Company's
informational Web site provides instant access to a library of back issues,
reviews, online links and chats with authors.
 
  Through ZD University, an Internet-based educational program, the Company
provided training to more than 37,000 paid subscribers in 1997, an increase of
100% from 1996. The ZD University Web site is closely integrated with ZDNet,
helping to ensure that customers of one service are exposed to other Company
services.
 
  Through the Help Desk Institute and the Support Services Professionals
Association, the Company provides training programs and publications for
hardware and software support service professionals. The Company also
publishes Inside Technology Training, which reaches 40,000 information
technology and training managers, and other software support professionals. In
addition, the Company owns and operates a single-site training center that
specializes in applications, programming and certification training for
Microsoft, Novell and Lotus, and the Training Center Alliance, which provides
qualifying training center customers with enhanced marketing support and
referral capabilities worldwide.
 
MARKET RESEARCH
 
  The Company's market research division develops, analyzes and compiles a
wide variety of information on computer technology issues ranging from
technical aspects of current usage to trends in decision making. The
 
                                      54
<PAGE>
 
Computer Intelligence ("CI") unit focuses on information concerning installed
and planned technology hardware and software purchases, and is a leading
source in North America and Europe of fact-based information concerning
hardware and software needs for the computer and communications industries. CI
is an important part of the Company's effort to be a single source marketing
solution, as it can provide the Company's marketing customers with important
information to identify their target customers. CI's databases are built from
more than 30,000 telephone interviews per month and contain data on installed
and planned computer and communications products and services at over 400,000
business sites in the U.S., Canada and eight European countries, according to
Company estimates. CI assists the Company's clients in identifying and
targeting their customers by tracking current activity and market share in the
business, home and reseller channels. Customers use CI's services to make
important marketing decisions.
 
  The Company also identifies and analyzes trends in the decision making
process for consumers of computer technology. This type of information helps
to identify criteria other than technical product specifications that are used
in product selection. The Company's market research division also consolidates
information obtained in each of the databases maintained by the Company's
other operating divisions, so that each Ziff-Davis division can offer the
Company's clients a wide range of information to meet their marketing needs
across multiple platforms.
 
  The Company publishes Microprocessor Report, a leading technical publication
for the microprocessor industry. It also produces Microprocessor Forum, the
industry's leading conference for the introduction of new high-performance
microprocessors, and PC Tech Forum, events which together attract more than
1,000 paid attendees and provide information on trends and markets.
 
COMPETITION
 
  The Company competes with a wide range of companies for each of the products
and services it provides. Although such competition is significant and is
likely to increase in the future, the Company believes it has a greater
breadth of product and service offerings than any of its competitors.
 
  The magazine publishing business is highly competitive. The Company faces
broad competition, not only from other technology publishers, but from other
media companies as well, including business, news and general interest
magazine publishers. Other principal computer and technology publishers in the
United States include IDG, CMP Media Inc., The McGraw-Hill Companies and
Imagine Publishing, each of which produces publications that directly compete
with one or more of the Company's publications. The Company also competes with
various computer and technology publishers in the international markets in
which it conducts business. A publishing company's success depends upon a
number of factors, such as editorial quality, product positioning and price.
Competitive factors for advertising sales include quality of readership,
circulation, reader response and advertising rates. The Company believes its
publications effectively compete in the marketplace on the basis of each of
these factors.
 
  The Company also faces competition in its trade show and conference
business, primarily from several significant trade show management companies.
These include Miller Freeman, Mecklermedia Corporation and IDG. The Company
believes its trade shows compete in the marketplace on the basis of quality of
conference content, organizational efficiency, and quality and number of
exhibitors and attendees.
 
  The Internet media business is highly competitive. An increasing number of
companies are developing online content and services for delivery on the World
Wide Web in order to compete for audiences and the advertising dollars that
are currently being directed to the Internet. ZDNet competes with other
technology-related online content sites such as c|net, CMPnet, and IDGnet.
 
  The Company's market research division faces competition from numerous
market research companies, including International Data Corporation, Gartner
Group's Dataquest and IntelliQuest. Database providers such as Information
Resource Group and Dun & Bradstreet provide additional competition.
 
                                      55
<PAGE>
 
  The Company's education division competes with a variety of education
providers, including vendor-supplied training materials and traditional
classroom-based computer training.
 
  ZDTV is expected to be the first 24-hour cable television channel and
integrated Web site focused on computer technology and the Internet, and as
such it is not expected to face direct competition in the near future. It
will, however, face competition from a variety of general and special interest
television programs. The market for television programming is highly
competitive, with many programming producers competing both for channel
carriage and for advertiser and audience market share.
 
TRADEMARKS
 
  The Company has developed strong brand awareness for its principal
publications, trade shows and other products and services. Accordingly, the
Company considers its trademarks, copyrights, trade secrets and similar
intellectual property as critical to its success and relies on trademark,
copyright and trade secrets laws, as well as licensing and confidentiality
agreements, to protect its intellectual property rights. The Company generally
registers its material trademarks in the United States and in certain other
key countries in which these trademarks are used. Effective trademark,
copyright and trade secret protection may not be available in every country in
which the Company's publications and services are available.
 
  The Company may be subject to claims of alleged infringement by it or its
licensees of trademarks and other intellectual property rights of third
parties from time to time in the ordinary course of business. The Company does
not believe there are any such legal proceedings or claims 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's world headquarters are located in New York and the Company has
over 50 editorial, production and sales offices and computer labs in many
other cities in the United States and around the world. The Company's other
principal offices are located in the Boston and San Francisco metropolitan
areas. The Company does not own real property that is material to its business
and leases all but one of its offices from third parties. 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, including space available under
lease options, will be available at commercially reasonable terms for future
expansion.
 
EMPLOYEES
 
  As of December 31, 1997, the Company had a total of 3,698 employees. Of
these employees, 1,160 were engaged in U.S. magazine publishing activities,
350 in international publishing activities, 728 in trade shows and
conferences, 197 in Internet-related activities, 414 in education activities,
486 in market research and 363 in central administrative services. None of the
Company's U.S. employees is represented by a labor union. The Company
considers its relationships with its employees to be satisfactory.
 
LEGAL PROCEEDINGS
 
  The Company has been named as a defendant in an action, filed on April 17,
1998, in the Supreme Court of the State of New York, by minority shareholders
of SOFTBANK Interactive Marketing Inc. ("SIM"), formerly an indirect
subsidiary of Softbank. The complaint alleges, among other things, that SBH,
SIM's majority shareholder, acting with the Company and two of its senior
officers and directors who were directors of SIM (and who are also named as
defendants), had conflicts of interest between SIM and other Softbank
investments (including investments in the Company) and failed to act in the
best interests of SIM and the minority shareholders by taking actions which
benefitted the Company. The complaint states claims based on common law fraud,
breach of fiduciary duty and aiding and abetting theories and seeks in excess
of $200 million in damages. The investment in SIM was solely by SBH, which
intends a vigorous defense on behalf of itself and the Company.
 
  There are no other legal proceedings to which the Company is a party, other
than ordinary routine litigation incidental to the business of the Company
which is not otherwise material to the business or financial condition of the
Company.

BOARD COMPOSITION
 
  Following the Offering, the Board of Directors will consist of ten members,
which will include the nine current members of the Board plus one additional
"independent director" (within the meaning of the regulations of the New York
Stock Exchange (the "NYSE")) nominated for election by the Board of Directors.
It is expected that the new director will be elected by the Board within three
months following the closing of the Offering. Directors of the Company are
currently elected annually by its stockholders to serve during the ensuing
year or until their respective successors are duly elected and qualified.
Following the Offering, the Board of Directors will be divided into three
classes each of whose members will serve for a staggered three-year term. Upon
the expiration of the term of a class of directors, directors in such class
will be elected for three-year terms at the annual meeting of stockholders in
the year in which such term expires.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
  The Board of Directors currently has two committees: an Audit Committee and
a Compensation Committee.
 
  The Audit Committee will be comprised of the independent directors. The
Audit Committee reviews and recommends to the Board, as it deems necessary,
the internal accounting and financial controls for the Company and the
accounting principles and auditing practices and procedures to be employed in
preparation and review of financial statements of the Company. The Audit
Committee makes recommendations to the Board concerning the engagement of
independent public accountants and the scope of the audit to be undertaken by
such accountants. Price Waterhouse LLP presently serves as the independent
accountants of the Company.
 
  The Compensation Committee is currently comprised of Mr. Fisher, who,
following the Offering, will be joined by the two independent directors. The
Committee reviews and, as it deems appropriate, recommends to the Board
policies, practices and procedures relating to the compensation of the
officers and other managerial employees and the establishment and
administration of employee benefit plans. The Committee exercises all
authority under any employee stock option plans of the Company as the
Committee therein specifies (unless the Board resolution appoints any other
committee to exercise such authority), and advises and consults with the
officers of the Company as may be requested regarding managerial personnel
policies. The Committee will have such additional powers and be granted
additional authority as may be conferred upon it from time to time by the
Board.
 
COMPENSATION OF DIRECTORS
 
  Directors who are not executive officers or employees of the Company or
Softbank will receive an annual retainer of $25,000 for Board of Directors
service and a fee of $2,000 for each meeting of the Board of Directors or any
committee thereof attended.
 
  The Company has adopted the 1998 Non-Employee Directors Stock Option Plan
(the "Non-Employee Directors Plan"). Directors of the Company who are not
employees of the Company or any of its subsidiaries ("Non-Employee Directors")
will automatically participate in the Non-Employee Directors Plan.
 
 
                                      59
<PAGE>
 
  Pursuant to the Non-Employee Directors Plan, each Non-Employee Director
shall receive upon election as a member of the Board an initial grant of stock
options to purchase 15,000 shares of Common Stock; provided, that each Non-
Employee Director who is on the Board of Directors on the date of the Offering
shall receive such initial grant of stock options on the date of the Offering.
Each Non-Employee Director shall automatically receive on each annual meeting
thereafter an annual grant of stock options to purchase 7,500 additional
shares of Common Stock. The terms of each stock option granted to a Non-
Employee Director shall provide that (i) the option price shall be equal to
100% of the fair market value (as defined in the 1998 Incentive Compensation
Plan) of the Common Stock on the date of grant, (ii) such option shall be
exercisable for a period of ten years following the date of grant, and (iii)
such option shall vest and become exercisable in five equal installments
beginning on the first anniversary of the date of grant.
 
  Upon ceasing to be a Non-Employee Director, such option shall terminate
except with respect to any portion of such option then exercisable, which
portion shall remain exercisable for a period of (x) 90 days, if the
termination as Director resulted from any reason other than death, disability
or Cause (as defined in the 1998 Incentive Compensation Plan), or (y) one
year, if the termination resulted from death or disability; provided, that in
the event the termination resulted from a removal for Cause, such option shall
immediately terminate and no longer be exercisable to any extent; provided,
further, that in no event shall any such option remain exercisable past the
remainder of its scheduled ten-year term.
 
  Upon a "change in control" of the Company (as defined in the Non-Employee
Directors Plan), each outstanding option shall fully vest and become
immediately exercisable in full. In addition, the Committee may provide in its
sole discretion that upon a change in control of the Company, each Non-
Employee Director shall be entitled to receive in cancellation of such Non-
Employee Director's outstanding and unexercised stock options, a cash payment
in an amount equal to the difference between the option price of such stock
options and (i) in the event the change of control is the result of a tender
offer or exchange offer for the Common Stock, the final offer price per share
paid for the Common Stock, multiplied by the number of shares of Common Stock
covered by such stock options, or (ii) in the event the change of control is
the result of any other occurrence, the aggregate value of the Common Stock
covered by such stock options, as determined by the Committee at such time.

STOCK PLANS
 
 Incentive Compensation Plan
 
  General.  The Company has adopted a 1998 Incentive Compensation Plan (the
"Plan") to provide long-term incentives for its key employees and enhance
shareholder value. The Plan will be administered by the Compensation Committee
(for purposes herein, the "Committee"), which will (i) select the
participants, determine the type of awards, and the number of shares or share
units subject to awards, and (ii) interpret the Plan and make all other
determinations necessary or advisable for its administration.
 
  All employees and consultants of the Company and its affiliates who have
demonstrated significant management potential or the capacity for contributing
substantially to the successful performance of the Company and its affiliates,
are eligible to be participants in the Plan. Awards may consist of stock
awards, stock options (either incentive stock options within the meaning of
Section 422 of the Internal Revenue Code or nonstatutory stock options), stock
appreciation rights, performance shares (which may be granted as performance
share units) and restricted stock (which may be granted as restricted stock
units).
 
  The Common Stock available for awards under the Plan shall not exceed
8,500,000 shares. In the event of any change in the outstanding shares by
reason of any stock dividend or split, recapitalization, merger or other
corporate change, or any distributions to common shareholders other than
regular cash dividends, the Committee may make such substitution or
adjustment, if any, as it deems to be equitable, as to the number or kind of
shares of Common Stock or other securities issued pursuant to the Plan and to
outstanding awards. Shares subject to an award that expires unexercised, is
forfeited, or terminated, or settled in cash in lieu of Common Stock, and
shares tendered to pay for the exercise of a stock option, shall thereafter
again be available for grant under the Plan.
 
  Each award under the Plan shall be evidenced by an agreement setting forth
the terms and conditions, as determined by the Committee, which apply to such
award. In the sole discretion of the Committee, a participant may be permitted
to defer the receipt of cash or Common Stock otherwise deliverable under any
award.
 
  Stock Options. The Committee shall establish the option price at the time
each stock option is granted, which price shall not be less than 100% of the
fair market value of the Common Stock on the date of grant. Stock options
shall vest and become exercisable at a rate determined by the Committee, and
shall remain exercisable for such period as specified by the Committee. The
award agreements in respect of options that are intended to qualify as
incentive stock options will contain any additional provisions necessary to
comply with the requirements of Section 422 of the Internal Revenue Code. In
no event may any employee receive in any calendar year grants of stock options
with respect to more than 1,000,000 shares of Common Stock.
 
  The option price of each share as to which a stock option is exercised will
be paid in full at the time of such exercise in cash, by tender of shares of
Common Stock owned by the participant valued at fair market value, by a "sale
to cover" broker transaction or other cashless exercise method permitted under
Regulation T of the Federal Reserve Board, or by a combination of cash, shares
of Common Stock and other consideration as the Committee deems appropriate.
 
  Stock Appreciation Rights. Stock appreciation rights ("SARs") may be granted
in tandem with a stock option or unrelated to a stock option. SARs shall vest
and become exercisable at a rate determined by the Committee, and shall remain
exercisable for such period as specified by the Committee. A SAR entitles its
holder to receive from the Company an amount equal to the excess of the fair
market value of a share of Common Stock on the exercise of the SAR over the
fair market value on the date of grant. The Committee may determine in its
sole discretion whether a SAR will be settled in cash, Common Stock or a
combination thereof. In no event may any employee receive in any calendar year
grants of SARs with respect to more than 500,000 shares of Common Stock.
 
  Performance Shares. Performance shares may be granted in the form of actual
shares of Common Stock or share units having a value equal to an identical
number of shares of Common Stock. The performance
 
                                      61
<PAGE>
 
conditions and the length of the performance period will be determined by the
Committee but in no event may a performance period be less than one year. The
Committee may determine in its sole discretion whether performance shares
granted in the form of share units shall be paid in cash, Common Stock, or a
combination thereof.
 
  Unless the Committee determines otherwise, awards of performance shares to a
Covered Employee will be subject to performance conditions based on the
achievement by the Company of target levels of items such as consolidated net
income, return on shareholders' equity, return on net assets or share price
performance. For purposes of the 1998 Incentive Compensation Plan, a "Covered
Employee" generally includes any employee that would be a covered employee
within the meaning of Section 162(m) of the Internal Revenue Code, and any
other employee of the Company or its subsidiaries designated by the Committee
in its discretion. The maximum number of performance shares subject to any
award to a Covered Employee is 500,000 for the first 12 months during the
performance period and each 12-month period thereafter.
 
  Restricted Stock. Restricted stock may be granted in the form of actual
shares of Common Stock or share units having a value equal to an identical
number of shares of Common Stock. The employment conditions and the length of
the period for vesting of restricted stock will be established by the
Committee at time of grant, except that each restriction period shall not be
less than twelve months. During the restricted period, shares of restricted
stock may not be sold, assigned, transferred or otherwise disposed of, or
pledged or hypothecated as collateral for a loan or as security for the
performance of any obligation or for any other purpose as the Committee shall
determine. The Committee may determine in its sole discretion whether
restricted stock granted in the form of share units will be paid in cash,
Common Stock or a combination thereof.
 
  Stock awards. In addition to awards of performance shares and restricted
stock, awards of Common Stock may be granted under the Plan in the form of
actual shares of Common Stock. Full ownership of such shares, whether issued
in the form of a certificate or in book entry, including the right to vote and
receive dividends, shall immediately vest in such participant.
 
  Change in Control. In the event of a Change in Control (as defined below):
(i) all stock options will be fully vested and exercisable in full; (ii) all
SARs which have not been granted in tandem with stock options will become
exercisable in full; (iii) the restrictions applicable to all shares of
restricted stock will lapse and such shares will be deemed fully vested and
all restricted stock granted in the form of share units will be paid in cash;
(iv) all performance shares will be deemed to be earned at target level; and
(v) all performance shares granted in the form of share units will be paid in
cash.
 
  For purposes of the Plan, "Change in Control" is generally defined as (i) a
change in the majority of the Board of Directors; except upon consent of
previous Board of Directors; (ii) certain mergers, consolidations or similar
corporate transactions in which the Company is not the surviving corporation
or entity; or (iii) the shareholders of the Company approve a plan of complete
liquidation or dissolution of the Company or a sale of all or substantially
all of the Company's assets; provided, that a Change in Control will not be
deemed to occur under clause (ii) if Softbank, directly or indirectly, is the
beneficial owner of more than 25% of the Company's voting securities or of the
voting securities of any surviving corporation, respectively.
 
  Amendment and Termination. The Board of Directors may amend, suspend or
terminate the Plan or any portion thereof at any time, provided that (a) no
amendment will be made without stockholder approval (including an increase in
the number of shares reserved for issuance under the Plan) if such approval is
necessary to comply with any applicable law, regulations or stock exchange
rule, and (b) except as otherwise provided under the cashout provisions in the
event of a Change in Control, no amendment will be made that would adversely
affect the rights of a participant under any award previously granted, without
such participant's written consent.
 
  Effective Date. The Plan will have a term of ten years from February 13,
1998, subject to earlier termination.

 Softbank Executive Stock Option Plans
 
  The SOFTBANK Group Executive Stock Option Plans (the "Softbank Plans")
authorize the grant of options to those officers, directors and key employees
of Softbank as selected by a committee appointed by the Board of Directors of
SOFTBANK Holdings Inc. The Softbank Plans authorize the granting of options to
purchase SOFTBANK Corp. common stock at not less than 100% of the closing
market price on the date the option is granted. As of December 31, 1997,
substantially all options granted become exercisable in various installments
over the first six anniversaries of the date of grant and expire ten years
after the date of grant.
 
  As of December 31, 1997, 966,986 options had been granted under the Softbank
Plans. On January 19, 1998, the exercise price of all options was reset at
4,000 Japanese yen per share, the market price of SOFTBANK Corp.'s common
stock on that date.
 
 Employee Stock Purchase Plan
 
  General. The Company has adopted an employee stock purchase plan (the "Stock
Purchase Plan"). The Stock Purchase Plan is intended to meet the applicable
requirements of Section 423 of the Internal Revenue Code and will be
administered by the Committee.
 
  Option to Purchase. Under the Stock Purchase Plan, all full-time and certain
part-time employees of the Company who meet certain minimum service
requirements will be eligible to purchase shares of Common Stock by means of
payroll deductions. Eligible employees may elect to participate in offering
periods by authorizing after-tax payroll deductions of between 1% and 10% (in
whole percentages) of their base pay for the purchase of shares of Common
Stock. The aggregate maximum number of shares of Common Stock purchasable
under the Stock Purchase Plan is 1,500,000, subject to adjustment by the
Committee in its sole discretion in the event of any increase, reduction or
change or exchange of shares of Common Stock for a different number or kind of
shares or other securities of the Company by reason of any stock dividend or
split, recapitalization, merger, consolidation, spin-off, combination or
exchange of shares or other corporate change, or any distribution to common
shareholders other than cash dividends. Upon the dissolution or liquidation of
the Company, or upon a reorganization, merger or consolidation of the Company
as a result of which the Company is not the surviving corporation, or upon a
sale of substantially all of the Company's assets, or a sale or distribution
of a subsidiary of the Company, any affected participant will thereafter be
entitled to receive, for each share of Common Stock subject to such
participant's option, the cash, securities and/or property which a holder of
one share of Common Stock was entitled to receive upon and at the time of such
transaction.
 
  The price at which shares of Common Stock will be purchased at the end of
each purchase period will be the lesser of (i) 85% of the Fair Market Value of
a share of Common Stock on the first business day of such purchase period or
(ii) 85% of the fair market value on the last business day of each purchase
period. No participating employee will be entitled in any calendar year to
purchase Common Stock having an aggregate fair market value as of the first
business day in any Purchase Period in excess of $25,000.
 
  Amendment and Termination. The Board may at any time terminate or amend the
Plan. No such termination shall adversely affect options previously granted
and no amendment may make any change in any option theretofore granted which
adversely affects the rights of any participant. No amendment shall be
effective unless approved by the shareholders of the Company if such
shareholder approval of such amendment is required to comply with any law,
regulation or stock exchange rule.

                             CERTAIN TRANSACTIONS
 
ARRANGEMENTS BETWEEN THE PRINCIPAL STOCKHOLDERS AND THE COMPANY
 
  The Company and Softbank have entered into certain agreements governing
ongoing business relationships between them, including: (i) a master license
agreement for Softbank's producing and distributing Ziff-Davis publications in
Japan; (ii) a license agreement for Softbank's operating ZDNet in Japan; and
(iii) a series of agreements, including a trademark license agreement,
technical assistance agreement and accounting and administrative services
agreement, pursuant to which the Company will manage all ZDCF trade shows and
conferences conducted in Japan, but owned by Softbank. Total revenue earned by
the Company from such trade show and conference agreements will approximate
50% of the pre-tax income generated by such trade shows and conferences.
 
  Softbank has given the Company an undertaking not to expand operations
involving (x) publishing information on computing and Internet-related
technology through the media of print, CD-Rom/DVD, Internet and television, or
(y) producing trade shows, conferences, exhibitions and similar events
primarily related to computing and Internet-related technology outside Japan
in competition with the Company without the prior approval of the Company's
management directors after consulting with the Company's independent
directors. This undertaking does not preclude investments by investment funds
managed by Softbank. Softbank manages certain venture capital funds which
invest in, among other things, computer and Internet-related companies. These
funds may be able to co-invest with the Company or compete with the Company
with respect to new investments. Softbank may develop new funds in the future,
which funds may compete with the Company for investment opportunities. The
Company has undertaken not to compete with Softbank in Japan without the prior
approval of SOFTBANK Corp.'s Board of Directors and to afford Softbank the
continuing right to license all of the Company's products and services in
Japan. See "Risk Factors--Control by Principal Stockholders and Potential
Conflicts of Interest."
 
  The Company and Softbank entered into a Registration Rights Agreement, dated
as of April 1, 1998, in connection with the Offering. The Agreement entitles
Softbank to require the Company to register any or all of the Common Stock
held by it in a public offering pursuant to the Securities Act of 1933, as
amended, as well as to "piggyback" or include its shares of Common Stock in
any registration of Common Stock made by the Company.
 
CERTAIN RELATED PARTY TRANSACTIONS
 
  The Company is a member of a group of companies affiliated through common
ownership under SOFTBANK Corp. and has various transactions and relationships
with members of the group, including SOFTBANK Corp.'s wholly-owned U.S.
subsidiary, SOFTBANK Holdings Inc. ("SBH"). Because of these relationships, it
is possible that the terms of the various transactions are not those that
would result from an arm's length dealing among unrelated parties.
 
  In December 1994, as part of the acquisition of ZD Expos, MAC purchased a
portion of the trade show assets for $45 million and its parent company, Son
Kosan Ltd., purchased an additional portion for $30 million. Concurrently with
the purchase of assets, SB Forums and Son Kosan Inc. entered into a management
agreement pursuant to which SB Forums agreed to provide management services
with respect to certain Son Kosan operations in Japan, France and Germany. SB
Forums earned approximately $808,000, $1,667,000 and $2,644,000 for such
services for the years ended December 31, 1995, 1996 and 1997 respectively.
Son Kosan's trade show assets were sold to SB Forums for $10 million in
January 1997 and certain of MAC's trade show assets are being contributed to
ZDCF as part of the Reorganization. See "The Reorganization."
 
  In February 1996, as part of the acquisition of ZD Pubco, MAC purchased
certain publishing assets for $302 million in cash. Concurrently with the sale
of assets, ZDI and MAC entered into a management agreement pursuant to which
ZDI agreed to provide management services with respect to the purchased
assets. The
 
                                      65
<PAGE>
 
Company earned approximately $2 million for such services for each of the
years ended December 31, 1996 and 1997, respectively. Of these assets, a
portion was transferred to ZDI for $100 million as of October 31, 1997 and the
balance will be sold to ZDI for $270 million concurrently with the Offering.
See "The Reorganization." The purchase price for the assets sold to ZDI was
not more than fair market value as determined by an independent appraiser.
 
  ZDI and Softbank entered into a series of license and syndication agreements
pursuant to which Softbank was granted the license to publish, or use certain
materials from, PC Week, Computer Shopper, PC Computing, MacWeek, Computer
Gaming World, PC Magazine and Internet Business Advantage. The Company earned
approximately $963,948 and $1,817,986 in connection therewith for the years
ended December 31, 1996 and 1997, respectively. Such agreements are being
combined into the master license agreement described above.
 
  The Company has advanced funds for the account of MAC in managing the MAC
Assets and ZDTV, bearing interest at the 30-day LIBOR rate plus .50%; subject
to periodic reimbursement by MAC. Such advances totalled $8.1 million, $68.2
million and $71.6 million in 1995, 1996 and 1997, respectively. The remaining
outstanding amount as of December 31, 1997 of $42.6 million will be reimbursed
in connection with the Reorganization. See Note 9 to the Notes to the Combined
Financial Statements of ZDI and ZDCF.
 
 
  During 1996 and 1997, the Company recorded revenues of approximately $.9
million and $2.7 million, respectively, from sales of advertising space and
trade show services to Kingston, an 80%-owned Softbank partnership. These
services were provided under terms consistent with those provided to
unaffiliated customers. See Note 9 of the Notes to the Combined Financial
Statements. Concurrently with the Offering the Company is entering into a
sale-leaseback transaction with Kingston. See "The Reorganization."
 
  In 1997 the Company had an arrangement with SOFTBANK Interactive Marketing
("SIM"), a 65.3%-owned Softbank subsidiary, for providing interactive media
sales. The Company paid SIM approximately $.6 million and $1.8 million in
commissions for the years ended December 31, 1996 and 1997, respectively.
Effective December 31, 1997, SIM was acquired by an unrelated third party and
the Company terminated its representation agreement with SIM. See Note 9 of
the Notes to the Combined Financial Statements of ZDI and ZDCF.
 
  During 1996 and 1997, the Company and Softbank were parties to a joint
venture agreement pursuant to which the Company managed all ZDCF trade shows
and conferences conducted in Japan. The Company earned approximately
$1,727,000 and $1,413,000 for such services for the years ended December 31,
1996 and 1997, respectively.
 
  During 1996 and 1997, the Company incurred $2 million and approximately $1.6
million in advertising expenses with Yahoo! Inc. which is 29.4% owned by
Softbank. Mr. Yang is co-founder and Chief Yahoo and Mr. Hippeau is a director
of Yahoo! Inc.
 
  During 1995 to 1997, the Company issued notes payable to Softbank in an
aggregate principal amount of $2.5 billion as of December 31, 1997,
principally for indebtedness incurred in the acquisition of ZD Expos, COMDEX
and ZD Pubco. See Note 9 of the Notes to the Combined Financial Statements.
 
  As part of the acquisition of the Company by its former owner in 1994, the
Company agreed to assume certain obligations to management arising out of
prior employment arrangements with Ziff Communications Company. In 1995 and
immediately after the end of the 1996 calendar year, the Company paid under
such arrangements $29,702,469 to Mr. Hippeau, the Company's Chairman and CEO
and a Director of the Company, and $1,014,565 to Mr. Sheer, the President of
ZD Publishing and a Director of the Company. See Note 9 to the Notes to the
Combined Financial Statements of ZDI and ZDCF.
 
  The Company has participated in the U.S. Softbank cash management program,
periodically transferring excess cash to SBH and in turn receiving cash
advances from SBH to fund the Company's short-term working
 
                                      66
<PAGE>
 
capital requirements. Under the program, interest is accrued based on the net
balance outstanding at the end of each month. Interest income is earned at the
30-day LIBOR rate. Interest expense is incurred at such rate plus .50%. As of
December 31, 1996 and 1997, such net cash transfers from the Company to SBH
amounted to $41.3 million and $76.5 million, respectively. See Note 9 of the
Notes to the Combined Financial Statements of ZDI and ZDCF.
 
  During 1997, the Company was a guarantor under SBH's $150 million loan
agreement with The Bank of New York, under which $102.5 million was
outstanding as of December 31, 1997, bearing interest at a weighted average
rate of 6.51% per annum. In March, 1998 this agreement was amended and
restated to increase the loan amount to $450 million. Under the amended
agreement, the Company is a guarantor under SBH's $450 million credit facility
with The Bank of New York, as agent, The Bank of New York and Morgan Stanley
Senior Funding, Inc., as lenders, and certain affiliate guarantors. The
agreement governing the credit facility contains certain restrictive covenants
and other provisions which bind the Company, but it does not prevent the
Company from consummating the Offering. Concurrently with the Reorganization,
the Company will repay obligations due to SBH; and it is expected that SBH
will use a portion of such proceeds to prepay the loans under the credit
facility and terminate the commitments thereunder.
 
  SBH and its subsidiary SBH Delaware have agreed to act as guarantors for
payments under the Company's lease for its new headquarters located at 28 East
28th Street, New York, New York. In addition, the various intercompany loans
from SBH Delaware to the Company were subordinated to the lease agreement. In
accordance with the terms of these agreements, these arrangements will
terminate when the Company and SBH meet minimum net worth levels of $850
million and $715 million, respectively, upon completion of the Offerings, at
which time the Company will become the sole guarantor under the lease.
 
  During 1997, the Company entered into an operating lease with GE Capital
Corp. for certain television production equipment that the Company subleased
to ZDTV on similar terms. This arrangement is expected to continue upon
completion of the Offering. The total amount of leased equipment will not
exceed $10 million.
 
  During 1997, the Company participated in a global insurance program
implemented by SBH. Upon completion of the Offering, it is expected that the
Company will remain a part of this program. The total amount of insurance
expenses allocated to the Company for the period from August 1, 1997 to July
30, 1998 does not exceed $1.35 million.

                      DESCRIPTION OF THE CREDIT FACILITY
 
  The following summary of certain material provisions of the Company's Credit
Facility does not purport to be complete and is subject to, and qualified in
its entirety by, the Company's Indenture (as defined below) and Credit
Facility, a copy of which has been filed as an exhibit to the Registration
Statement of which this Prospectus forms a part and by the provisions of
applicable law. See "Additional Information."
 
CREDIT FACILITY
 
  The Company has obtained a commitment letter from The Bank of New York,
Morgan Stanley Senior Funding, DLJ Capital Funding and The Chase Manhattan
Bank to provide a $1.35 billion Credit Facility. In connection with the
Reorganization, the Company will enter into the Credit Facility and borrow
$1.25 billion thereunder. The Credit Facility will consist of a seven year
$500 million reducing revolving credit facility (with $400 million drawn at
consummation of the Offerings), a seven year $450 million term loan and an
eight year $400 million term loan. The revolving credit commitments will be
reduced and the $450 million term loan will be amortized beginning in
September 2000, by (x) 10% in 2000, in two equal quarterly installments, (y)
20% in each of 2001, 2002, 2003 and 2004 in four equal quarterly installments
and (z) 10% at final maturity in March, 2005. The $400 million term loan will
be amortized, beginning in September 2000, by (x) $2 million in 2000, in two
equal quarterly installments, (y) $4 million in each of 2001, 2002, 2003, 2004
and 2005 in four equal quarterly installments and (z) $378 million at final
maturity in March 2006. The Credit Facility will be secured, in part, by a
first priority security interest in capital stock of certain subsidiaries of
the Company and will be guaranteed by certain wholly-owned domestic
subsidiaries of the Company (in each case, including ZDI and ZDCF).
 
  Amounts available under the Credit Facility will be available for loans,
Letters of Credit, and swing-line loans, subject to a certain maximum level of
borrowing. The Credit Facility will also provide the Company with the ability
to increase the revolving credit portion by $300 million to $1 billion at any
time prior to June, 2000 if the banks agree to increase their commitments.
 
  Loans under both the revolving credit and term loan portions of the Credit
Facility will bear interest at either LIBOR plus an applicable margin or the
Alternate Base Rate plus an applicable margin. The applicable margin will be
based on a pricing grid to be determined by the Company's ratio of debt to
EBITDA. The Company will also pay a commitment fee on the unused portion of
the revolving credit.
 
  The Credit Facility will contain certain customary affirmative and negative
covenants, including covenants (subject to certain exceptions) with respect
to, among other things, the delivery of financial statements and other
information, limitations on dispositions of assets, changes of business and
ownership, mergers or acquisitions, restricted payments, indebtedness, loans
and investments, and transactions with affiliates, negative pledge of assets,
maintenance of adequate and customary insurance coverage, compliance with all
applicable laws and regulations, and restriction on modifications of certain
agreements, charter documents or other material documents without the consent
of the lenders. The Credit Facility will also contain certain financial
covenants.
 
  The failure to satisfy any of the covenants would constitute an Event of
Default under the Credit Facility. The Credit Facility will also include other
customary events of default, including, without limitation, nonpayment,
misrepresentation in a material respect, cross-default to other indebtedness,
bankruptcy, ERISA, judgments and change of control.
 
  The Credit Facility is subject to certain terms and conditions, including
without limitation negotiation, execution and delivery of definitive financing
agreements, in each case containing terms and conditions, representations and
warranties, covenants, indemnifications, events of default and conditions to
lending.

                             DESCRIPTION OF NOTES
 
  The Notes are to be issued under an Indenture, dated as of the Issue Date
(the "Indenture"), between the Company and The Bank of New York, as Trustee
(the "Trustee"), a copy of which has been filed as an exhibit to the
Registration Statement of which this Prospectus forms a part. The following
summary of certain material provisions of the Indenture and the Notes does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, all the provisions of the Indenture and the Notes, including the
definitions of certain terms therein and those terms made a part thereof by
the Trust Indenture Act of 1939, as amended. Whenever particular Sections or
defined terms of the Indenture not otherwise defined herein are referred to,
such Sections or defined terms are incorporated herein by reference. For
purposes of this Section, references to the Company mean the Registrant,
excluding its subsidiaries. For definitions of certain capitalized terms used
herein, see "--Certain Definitions."
 
GENERAL
 
  The Notes will be unsecured senior subordinated obligations of the Company,
limited to $250 million aggregate principal amount, and will mature on May 1,
2008. The Notes will bear interest at the rate per annum shown on the cover
page of this Prospectus from the Issue Date or from the most recent Interest
Payment Date to which interest has been paid or provided for, payable
semiannually (to Holders of record at the close of business on the April 15 or
October 15 immediately preceding the Interest Payment Date (each, a "Regular
Record Date")) on the May 1 and November 1 of each year, commencing November
1, 1998.
 
  Principal of, premium, if any, and interest on the Notes will be payable,
and the Notes may be exchanged or transferred, at the office or agency of the
Company in the Borough of Manhattan, The City of New York (which initially
will be the corporate trust office of the Trustee at 101 Barclay Street, New
York, New York 10286); provided that, at the option of the Company, payment of
interest may be made by check mailed to the address of the Holders as such
address appears in the Security Register.
 
  The Notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount and any integral multiple thereof.
No service charge will be made for any registration of transfer or exchange of
Notes, but the Company may require payment of a sum sufficient to cover any
transfer tax or other similar governmental charge payable in connection
therewith.
 
SINKING FUND
 
  There will be no sinking fund payments for the Notes.
 
OPTIONAL REDEMPTION
 
  Except as set forth in the following paragraph, the Notes will not be
redeemable at the option of the Company prior to May 1, 2003. Thereafter, the
Notes will be redeemable, at the Company's option, in whole or in part, at any
time or from time to time and prior to maturity, upon not less than 30 nor
more than 60 days' prior notice mailed by first class mail to each Holder's
last address as it appears in the Security Register, at the following
redemption prices (expressed in percentages of principal amount), plus accrued
and unpaid interest, if any, to the redemption date (subject to the right of
Holders of record on the relevant Regular Record Date to receive interest due
on an Interest Payment Date that is on or prior to the redemption date), if
redeemed during the 12-month period commencing May 1 of the years set forth
below:

  In addition, at any time and from time to time prior to May 1, 2001, the
Company may redeem in the aggregate up to 35% of the original principal amount
of the Notes with the proceeds of one or more Public Equity Offerings
commenced after the Issue Date, at a redemption price (expressed as a
percentage of principal amount) of 108.5% plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
Regular Record Date to receive interest due on an Interest Payment Date that
is on or prior to the redemption date); provided that at least $150 million
aggregate principal amount of the Notes must remain outstanding after each
such redemption; and provided further that any such redemption shall occur
within 60 days of the date of the closing of such Public Equity Offering.
 
  In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee, on a pro rata basis, by lot or by such other
method as the Trustee in its sole discretion shall deem to be fair and
appropriate; provided that no Note of $1,000 in principal amount or less shall
be redeemed in part. If any Note is to be redeemed in part only, the notice of
redemption relating to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation of the original Note.
 
RANKING AND SUBORDINATION
 
  The Notes will be senior subordinated Indebtedness of the Company. The
payment of the Senior Subordinated Obligations will, to the extent set forth
in the Indenture, be subordinated in right of payment to the prior payment in
full, in cash or cash equivalents, of all Senior Indebtedness. After giving
pro forma effect to the Reorganization, as of December 31, 1997, the Company
would have had approximately $1.34 billion of Indebtedness (other than the
Notes), all of which would have been Senior Indebtedness. See
"Capitalization." In addition, all existing and future liabilities (including
Trade Payables) of the Subsidiaries of the Company will be effectively senior
to the Notes. After giving pro forma effect to the Reorganization, as of
December 31, 1997, the Company's Subsidiaries would have had approximately
$497.4 million of liabilities (excluding Indebtedness owed to the Company).
See "Risk Factors--Subordination of the Notes; Dependence on Subsidiaries."
 
  Upon any payment or distribution of assets or securities of the Company of
any kind or character, whether in cash, property or securities, upon any
dissolution or winding up or total or partial liquidation or reorganization of
the Company, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness (including any interest accruing on or after, or which
would accrue but for, an event of bankruptcy, whether or not such interest is
an allowed claim enforceable against the debtor under the United States
Bankruptcy Code) shall first be paid in full, in cash or cash equivalents,
before the Holders of the Notes or the Trustee on behalf of the Holders of the
Notes shall be entitled to receive any payment by the Company on account of
Senior Subordinated Obligations or any payment to acquire any of the Notes for
cash, property or securities, or any distribution with respect to the Notes of
any cash, property or securities. Before any payment may be made by, or on
behalf of, the Company on any Senior Subordinated Obligations, upon any such
dissolution, winding up, liquidation or reorganization, any payment or
distribution of assets or securities of the Company of any kind or character,
whether in cash, property or securities, to which the Holders of the Notes or
the Trustee on behalf of the Holders of the Notes would be entitled, but for
the subordination provisions of the Indenture, shall be made by the Company or
by any receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person making such payment or distribution or by the Holders of the
Notes or the Trustee if received by them or it, directly to the holders of the
Senior Indebtedness (pro rata to such holders on the basis of the respective
amounts of Senior Indebtedness held by such holders) or their representatives
or to any trustee or trustees under any indenture pursuant to which any such
Senior Indebtedness may have been issued, as their respective interests
appear, to the extent necessary to pay all such Senior Indebtedness in full,
in cash or cash equivalents after giving effect to any concurrent payment,
distribution or provision therefor to or for the holders of such Senior
Indebtedness. However, notwithstanding the foregoing, Holders of Notes may
receive securities so long as (i) the Notes are not treated in any case or
proceeding or other event described above as part of the same class of claims
as the Senior Indebtedness or any class of claims on a parity with or senior
to the Senior Indebtedness for any payment or distribution, (ii) such
 
                                      71
<PAGE>
 
securities are subordinated at least to the same extent as the Notes to Senior
Indebtedness of the Company and any securities issued in exchange for such
Senior Indebtedness and (iii) such securities are authorized by an order
or decree of a court of competent jurisdiction in a reorganization proceeding
under any applicable bankruptcy, insolvency or similar law which gives effect
to the subordination of the Notes to Senior Indebtedness in a manner and with
an effect which would be required if this sentence were not included in this
paragraph.
 
  No direct or indirect payment by or on behalf of the Company of Senior
Subordinated Obligations, whether pursuant to the terms of the Notes or upon
acceleration or otherwise, shall be made if, at the time of such payment,
there exists a default in the payment of all or any portion of the obligations
under or with respect to any Senior Indebtedness of the Company and such
default shall not have been cured or waived or the benefits of this sentence
waived by or on behalf of the holders of such Senior Indebtedness. In
addition, during the continuance of any other event of default with respect to
any Designated Senior Indebtedness pursuant to which the maturity thereof may
be accelerated, upon receipt by the Trustee of written notice from the trustee
or other representative for the holders of such Designated Senior Indebtedness
(or the holders of at least a majority in principal amount of such Designated
Senior Indebtedness then outstanding), no payment of Senior Subordinated
Obligations may be made by or on behalf of the Company upon or in respect of
the Notes for a period (a "Payment Blockage Period") commencing on the date of
receipt of such notice and ending 179 days thereafter (unless, in each case,
such Payment Blockage Period shall be terminated (i) by written notice to the
Trustee from such trustee of, or other representatives for, such holders or
(ii) by such event of default having been cured or waived or otherwise ceasing
to exist or (iii) by payment in full in cash or cash equivalents of such
Designated Senior Indebtedness). Not more than one Payment Blockage Period may
be commenced with respect to the Notes during any period of 360 consecutive
days. Notwithstanding anything in the Indenture to the contrary, there must be
180 consecutive days in any 360-day period in which no Payment Blockage Period
is in effect. No event of default that existed or was continuing (it being
acknowledged that any subsequent action that would give rise to an event of
default pursuant to any provision under which an event of default previously
existed or was continuing shall constitute a new event of default for this
purpose) on the date of the commencement of any Payment Blockage Period with
respect to the Designated Senior Indebtedness initiating such Payment Blockage
Period shall be, or shall be made, the basis for the commencement of a second
Payment Blockage Period by the representative for, or the holders of, such
Designated Senior Indebtedness, whether or not within a period of 360
consecutive days, unless such event of default shall have been cured or waived
for a period of not less than 90 consecutive days.
 
  To the extent any payment of Senior Indebtedness (whether by or on behalf of
the Company, as proceeds of security or enforcement of any right of setoff or
otherwise) is declared to be fraudulent or preferential, set aside or required
to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar Person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then if such payment is recovered by, or
paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar Person, the Senior Indebtedness or part thereof originally
intended to be satisfied shall be deemed to be reinstated and outstanding as
if such payment had not occurred. To the extent the obligation to repay any
Senior Indebtedness is declared to be fraudulent, invalid, or otherwise set
aside under any bankruptcy, insolvency, receivership, fraudulent conveyance or
similar law, then the obligation so declared fraudulent, invalid or otherwise
set aside (and all other amounts that would come due with respect thereto had
such obligation not been so affected) shall be deemed to be reinstated and
outstanding as Senior Indebtedness for all purposes hereof as if such
declaration, invalidity or setting aside had not occurred.
 
  If the Company fails to make any payment on the Notes when due or within any
applicable grace period, whether or not on account of the payment blockage
provision referred to above, such failure would constitute an Event of Default
under the Indenture and would enable the Holders to accelerate the maturity
thereof. See "--Events of Default."
 
  By reason of the subordination provisions described above, in the event of
liquidation or insolvency, creditors of the Company who are not holders of
Senior Indebtedness may recover less, ratably, than holders of Senior
Indebtedness and may recover more, ratably, than Holders of the Notes.
 
                                      72
<PAGE>
 
  The subordination provisions described above will cease to be applicable to
the Notes upon any defeasance of the Notes described under "--Defeasance."

  amount not to exceed the amount so refinanced or refunded (plus premiums,
  accrued interest, fees and expenses); provided that Indebtedness the
  proceeds of which are used to refinance or refund the Notes or Indebtedness
  that is pari passu with, or subordinated in right of payment to, the Notes

  refinanced in part or the Indebtedness to be refinanced is pari passu with
  the Notes, such new Indebtedness, by its terms or by the terms of any
  agreement or instrument pursuant to which such new Indebtedness is
  outstanding, is expressly made pari passu with, or subordinate in right of
  payment to, the remaining Notes, (B) in case the Indebtedness to be
  refinanced is subordinated in right of payment to the Notes, such new
  Indebtedness, by its terms or by the terms of any agreement or instrument
  pursuant to which such new Indebtedness is outstanding, is expressly made
  subordinate in right of payment to the Notes at least to the extent that
  the Indebtedness to be refinanced is subordinated to the Notes and (C) such
  new Indebtedness, determined as of the date of Incurrence of such new
  Indebtedness, does not mature prior to the Stated Maturity of the
  Indebtedness to be refinanced or refunded, and the Average Life of such new
  Indebtedness is at least equal to the remaining Average Life of the
  Indebtedness to be refinanced or refunded; and provided further that in no
  event may Indebtedness of the Company be refinanced pursuant to this clause
  (vi) by means of any Indebtedness of any Restricted Subsidiary;
 
                                      73
<PAGE>
 
    (vii) Indebtedness of the Company or any Restricted Subsidiary (A) in
  respect of bid, performance, surety or appeal bonds provided in the
  ordinary course of business consistent with past practice, (B) under
  Currency Agreements and Interest Rate Agreements (provided that such
  Currency Agreements do not increase the Indebtedness of the obligor
  outstanding at any time other than as a result of fluctuations in foreign
  currency exchange rates or by reason of fees, indemnities and compensation
  payable thereunder) or (C) arising from agreements providing for
  indemnification, adjustment of purchase price or similar obligations, or
  from Guarantees or letters of credit, surety bonds or performance bonds
  securing any obligations of the Company pursuant to such agreements, in any
  case Incurred in connection with the disposition of any business, assets or
  Restricted Subsidiary (other than Guarantees of Indebtedness Incurred by

  principal amount not to exceed the gross proceeds actually received by the
  Company or any Restricted Subsidiary in connection with such disposition;
 
    (viii) Indebtedness of the Company or any Restricted Subsidiary under

  the application of the proceeds therefrom, the Company could Incur at least
  $1.00 of Indebtedness under the first paragraph above.
 
  For purposes of determining compliance with the "Limitation on Indebtedness"
covenant described in the two preceding paragraphs, (A) in the event that an
item of Indebtedness meets the criteria of more than one of the types of
Indebtedness described in the clauses of the preceding paragraph, the Company,
in its sole discretion, shall classify such item of Indebtedness and only be
required to include the amount and type of such Indebtedness in one of such
clauses, (B) an item of Indebtedness may be divided and classified in more
than one of the types of Indebtedness described above and (C) the amount of
Indebtedness issued at a price that is less than the principal amount thereof

  Stock (other than Redeemable Stock) or (y) pro rata dividends or
  distributions on Common Stock of Restricted Subsidiaries held by minority

  its Restricted Subsidiaries); provided, that this clause (iii) shall not
  apply to the Existing Softbank Note; or
 
    (iv) make any Investment that is a Restricted Investment;
 
if, at the time of, and after giving effect to, the proposed Restricted

continuing, (B) the Company could not Incur at least $1.00 of Indebtedness
under the first paragraph of the "Limitation on Indebtedness" covenant or (C)

Resolution) after the Issue Date would exceed the sum of (1) the remainder of
(x) the aggregate amount of Consolidated EBITDA (or, if the Consolidated
EBITDA is negative, minus 100% of such negative amount) accrued on a
cumulative basis during the period (taken as one accounting period) beginning

subsequent to the Issue Date upon the conversion or exchange of such
Indebtedness into Capital Stock (other than Redeemable Stock) of the Company,
or from the issuance to any Person who is not a Subsidiary of any options,
warrants or other rights to acquire Capital Stock of the Company (in each

reduction in Restricted Investments in any Person resulting from payments of
dividends, repayments of loans or advances, or other transfers of assets, in
each case to the Company or any Restricted Subsidiary or from the Net Cash
Proceeds from the sale of any such Investment (except, in each case, to the
extent any such payment or proceeds are included in the calculation of
Adjusted Consolidated Net Income), or from redesignations of Unrestricted
Subsidiaries as Restricted Subsidiaries (valued in each case as provided in
the definition of "Investments"), not to exceed, in each case, the amount of
Investments previously made by the Company and any Restricted Subsidiary in
such Person or Unrestricted Subsidiary.
 
  The foregoing provision shall not be violated by reason of: (i) the payment

said date of declaration, such payment would comply with the foregoing
paragraph; (ii) the redemption, repurchase, defeasance or other acquisition or
retirement for value of Subordinated Obligations including premium, if any,
and accrued and unpaid interest, with the proceeds of, or in exchange for,
Permitted Refinancing Indebtedness; (iii) the repurchase, redemption or other
acquisition of Capital Stock of the Company in exchange for, or out of the
proceeds of a substantially concurrent offering of, shares of Capital Stock
(other than Redeemable Stock) of the Company; (iv) the making of any principal

employment or pursuant to any agreement under which such shares of stock or
related rights were issued; provided that the aggregate cash consideration
paid for such purchase, redemption, acquisition, cancellation or other
retirement of such shares of Capital Stock or related rights after the Issue
Date does not exceed an aggregate amount of $10 million in any twelve month
period; (vi) Investments acquired in exchange for Capital Stock (other than
Redeemable Stock) of the Company; (vii) payments or distributions pursuant to
or in connection with a consolidation, merger or transfer of assets that

<PAGE>
 
Company, (viii) Investments by the Company or any of its Restricted
Subsidiaries in a joint venture or joint ventures with any Person or Persons
in an aggregate amount not to exceed $75 million, provided that such joint
venture or joint ventures is or are engaged in a business that is similar or
related, ancillary or complementary to the nature or type of the business of
the Company and its Restricted Subsidiaries and joint venture companies
existing on the date of such Investment (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and evidenced by a
Board Resolution) and provided, further, that the Company may make up to $150
million of additional Investments under this clause (viii) in lieu of
Investments permitted to be made, but not made, pursuant to clause (ix)
hereof, (ix) Investments by the Company or any of its Restricted Subsidiaries
in an aggregate amount not to exceed $150 million in connection with the ZDTV
Acquisition; provided, that the amount of such Investments permitted under
this clause (ix) shall be reduced by the amount of Investments in excess of
$75 million made pursuant to clause (viii) hereof; or (x) any other Restricted
Payment which, together with all other Restricted Payments made pursuant to
this clause (x) since the Issue Date, does not exceed $25 million; provided
that, except in the case of clauses (i) and (iii), no Default or Event of
Default shall have occurred and be continuing or occur as a consequence of the
actions or payments set forth therein. The amount of any Restricted Payments
permitted pursuant to clauses (viii), (ix) or (x) above shall be determined
after giving effect to the net reduction in the amount of any Investment made
pursuant to such clause (viii), (ix) or (x), respectively, to the extent
contemplated by clause (3) of the first paragraph above of this "Limitation on
Restricted Payments" covenant.
 
  Each Restricted Payment permitted pursuant to the preceding paragraph
(excluding Restricted Payments referred to in clauses (ii), (vi), (viii) and
(ix)) and the Net Proceeds from any issuance of Capital Stock referred to in
clauses (iii), (iv) and (vi) shall (without duplication) be included in
calculating whether the conditions of clause (C) of the second preceding
paragraph have been met with respect to any subsequent Restricted Payments.
 
 Limitation on Senior Subordinated Indebtedness
 
  The Company shall not Incur any Indebtedness that is subordinate in right of
payment to any Senior Indebtedness unless such Indebtedness is pari passu
with, or subordinated in right of payment to, the Notes; provided that the
foregoing limitation shall not apply to distinctions between categories of
Senior Indebtedness of the Company that exist by reason of any Liens or
Guarantees arising or created in respect of some but not all such Senior
Indebtedness.
 
 Limitation on Liens
 
  The Company shall not Incur any Indebtedness secured by a Lien ("Secured
Indebtedness") which is not Senior Indebtedness (or Indebtedness that would
constitute Senior Indebtedness except that it is without recourse to the
Company) unless contemporaneously therewith effective provision is made to
secure the Notes equally and ratably with (or, if the Secured Indebtedness is
subordinated in right of payment to the Notes, prior to) such Secured
Indebtedness for so long as such Secured Indebtedness is secured by a Lien.
 
 Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries
 
  The Company will not, and will not permit any Restricted Subsidiary to,
create or otherwise cause or suffer to exist or become effective any
consensual encumbrance or restriction of any kind on the ability of any
Restricted Subsidiary to (i) pay dividends or make any other distributions
permitted by applicable law on any Capital Stock of such Restricted Subsidiary
owned by the Company or any other Restricted Subsidiary, (ii) pay any
Indebtedness or other obligations owed to the Company or any other Restricted
Subsidiary, (iii) make loans or advances to the Company or any other
Restricted Subsidiary or (iv) transfer any of its property or assets to the
Company or any other Restricted Subsidiary.
 
  The foregoing provisions shall not restrict any encumbrances or
restrictions: (i) existing on the Issue Date in the Credit Agreement, the
Indenture or any other agreements in effect on the Issue Date, and any
extensions, amendments, refinancings, renewals or replacements of any of the
foregoing; provided that the encumbrances
 
                                      76
<PAGE>
 
and restrictions in any such extensions, amendments, refinancings, renewals or
replacements are no less favorable in any material respect to the Holders than
those encumbrances or restrictions that are then in effect and that are being
extended, amended, refinanced, renewed or replaced; (ii) existing under or by
reason of applicable law; (iii) existing with respect to any Person or the
property or assets of such Person acquired by the Company or any Restricted
Subsidiary and existing at the time of such acquisition, which encumbrances or
restrictions (A) are not applicable to any Person or the property or assets of
any Person other than such Person or the property or assets of such Person so
acquired and (B) were not put in place in anticipation of such acquisition,
and any extensions, refinancings, renewals or replacements of any of the
foregoing; provided that the encumbrances and restrictions in any such
extensions, refinancings, renewals or replacements are no less favorable in
any material respect to the Holders than those encumbrances or restrictions
that are then in effect and that are being extended, refinanced, renewed or
replaced; (iv) in the case of clause (iv) of the preceding paragraph, (A) that
restrict in a customary manner the subletting, assignment or transfer of any
property or asset that is subject to a lease, license, conveyance or contract,
(B) existing by virtue of any transfer of, agreement to transfer, option or
right with respect to, or Lien on, any property or assets of the Company or
any Restricted Subsidiary not otherwise prohibited by the Indenture or (C)
arising or agreed to in the ordinary course of business, not relating to any
Indebtedness and, that do not, individually or in the aggregate, detract from
the value of property or assets of the Company or any Restricted Subsidiary in
any manner material to the Company or any Restricted Subsidiary; (v) with
respect to a Restricted Subsidiary and imposed pursuant to an agreement that
has been entered into for the sale or disposition of all or substantially all
of the Capital Stock of, or property and assets of, such Restricted Subsidiary
or (vi) contained in the terms of any Indebtedness or any agreement pursuant
to which such Indebtedness was issued if (A) the encumbrance or restriction
applies only in the event of a payment default or a default with respect to a
financial covenant contained in such Indebtedness or agreement, (B) the
encumbrance or restriction is not materially more disadvantageous to the
Holders of the Notes than is customary in comparable financings (as determined
by the Company) and (C) the Company determines that any such encumbrance or
restriction will not materially affect the Company's ability to make principal
or interest payments on the Notes. Nothing contained in the preceding
paragraph shall prevent the Company or any Restricted Subsidiary from (1)
creating, incurring, assuming or permitting to exist any Lien otherwise not
prohibited by the Indenture or (2) restricting the sale or other disposition
of property or assets of the Company or any of its Restricted Subsidiaries
that secure Indebtedness of the Company or any of its Restricted Subsidiaries.
 
 Limitation on the Issuance of Capital Stock of Restricted Subsidiaries
 
  The Company will not sell, and will not permit any Restricted Subsidiary,
directly or indirectly, to issue or sell any shares of Capital Stock of a
Restricted Subsidiary (including options, warrants or other rights to purchase
shares of such Capital Stock) except (i) to the Company or a Wholly Owned
Restricted Subsidiary, (ii) issuances or sales to foreign nationals of shares
of Capital Stock of foreign Restricted Subsidiaries, to the extent required by
applicable law, (iii) if, immediately after giving effect to such issuance or
sale, such Restricted Subsidiary would no longer constitute a Restricted
Subsidiary; provided that any Investment in such Person remaining after giving
effect to such issuance or sale would have been permitted to be made under the
"Limitation on Restricted Payments" covenant, if made on the date of such
issuance or sale, (iv) to the extent such shares represent directors'
qualifying shares or (v) issuances or sales of Common Stock of a Restricted
Subsidiary that remains a Restricted Subsidiary after such transaction, the
Net Cash Proceeds from which are applied in compliance with clause (A) or (B)
of the "Limitation on Asset Sales" covenant.
 
 Limitation on Issuances of Guarantees by Restricted Subsidiaries
 
  The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company or any Restricted
Subsidiary (except Indebtedness of a Restricted Subsidiary of such Restricted
Subsidiary) ("Guaranteed Indebtedness"), unless (i) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture to the Indenture
providing for a Guarantee (a "Subsidiary Guarantee") of payment of the Notes
by such Restricted Subsidiary and (ii) such Restricted Subsidiary waives and
will not in any manner whatsoever claim or take the benefit or advantage of
any rights of reimbursement,
 
                                      77
<PAGE>
 
indemnity or subrogation or any other rights against the Company or any other
Restricted Subsidiary as a result of any payment by such Restricted Subsidiary
under its Subsidiary Guarantee; provided that this paragraph shall not be
applicable to (I) any Guarantee of any Restricted Subsidiary that existed at
the time such Person became a Restricted Subsidiary and was not Incurred in
connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary, (II) Guarantees permitted under clause (iv) of the second
paragraph of the "Limitation on Indebtedness" covenant, (III) any Guarantee by
any Restricted Subsidiary of Indebtedness Incurred under the Credit Agreement
and permitted by the Indenture, (IV) any Guarantee by any Restricted
Subsidiary of Indebtedness Incurred by the Company under any senior commercial
term loan and/or revolving credit facility entered into principally with
commercial banks and/or other financial institutions typically party to
commercial loan agreements and permitted by the Indenture or (V) any Guarantee
by any Restricted Subsidiary of Indebtedness Incurred by another Restricted
Subsidiary and permitted by the Indenture. If the Guaranteed Indebtedness is
(A) pari passu with the Notes, then the Guarantee of such Guaranteed
Indebtedness shall be pari passu with, or subordinated to, the Subsidiary
Guarantee or (B) subordinated to the Notes, then the Guarantee of such
Guaranteed Indebtedness shall be subordinated to the Subsidiary Guarantee at
least to the extent that the Guaranteed Indebtedness is subordinated to the
Notes.
 
  Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary shall provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or
transfer to any Person not an Affiliate of the Company, of all of the Capital
Stock of such Restricted Subsidiary directly or indirectly owned by the
Company, or all or substantially all the assets of such Restricted Subsidiary
(which sale, exchange or transfer is not prohibited by the Indenture) or (ii)
the release or discharge of the Guarantee which resulted in the creation of
such Subsidiary Guarantee, except a discharge or release by or as a result of
payment under such Guarantee.
 
 Limitation on Asset Sales
 
  The Company will not, and will not permit any Restricted Subsidiary to,
consummate any Asset Sale unless: (i) such Asset Sale is effected at not less
than fair market value (as determined in good faith by the Board of
Directors); and (ii) either (x) at least 75% of the consideration is received
in cash, Temporary Cash Investments or the assumption of Indebtedness (other
than Subordinated Obligations) or (y) the consideration therefor received by
the Company or any Restricted Subsidiary is in the form of equity or debt
securities of the transferee of such assets; provided, that Asset Sales
pursuant to this clause (y) shall not exceed an aggregate of $25 million in
any twelve month period. In the event and to the extent that the Net Cash
Proceeds received by the Company or its Restricted Subsidiaries from one or
more Asset Sales occurring on or after the Issue Date in any period of 12
consecutive months exceed $20 million, the Company, shall, or shall cause one
or more of its Restricted Subsidiaries to, (1) within twelve months after the
date such Net Cash Proceeds exceed $20 million, (A) apply an amount equal to
such excess Net Cash Proceeds to permanently repay Senior Indebtedness of the
Company or Indebtedness of any Restricted Subsidiary, as the case may be, in
each case owing to a Person other than the Company or any of its Restricted
Subsidiaries or (B) invest an equal amount, or the amount not so applied
pursuant to clause (A) (or enter into a definitive agreement committing to so
invest within 12 months after the date of such agreement), in the business of
the Company and its Restricted Subsidiaries as of the date of application of
such amounts (or in Capital Stock of a Restricted Subsidiary or a Person
engaged either in the same business as the Company or any of its Restricted
Subsidiaries or a business related, ancillary or complementary thereto that,
as a result of such Investment, becomes a Restricted Subsidiary) and (2) apply
such excess Net Cash Proceeds (to the extent not applied pursuant to clause
(1) above) as provided in the following three paragraphs. The amount of such
excess Net Cash Proceeds required to be applied (or to be committed to be
applied) during such 12-month period as set forth in clause (1) of the
preceding sentence and not applied as so required by the end of such period
shall constitute "Excess Proceeds."
 
  If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Excess Proceeds Offer (as
defined below) totals at least $20 million, the Company must, not later than
the fifteenth Business Day of such month, make an offer (an "Excess Proceeds
Offer") to purchase from
 
                                      78
<PAGE>
 
the Holders on a pro rata basis an aggregate principal amount of Notes equal
to the Excess Proceeds on such date, at a purchase price equal to 100% of the
principal amount of the Notes, plus, in each case, accrued interest (if any)
to the date of purchase (the "Excess Proceeds Payment").
 
  The Company will commence an Excess Proceeds Offer by mailing a notice to
the Trustee and each Holder stating: (i) that the Excess Proceeds Offer is
being made pursuant to the "Limitation on Asset Sales" covenant of the
Indenture and that all Notes validly tendered will be accepted for payment on
a pro rata basis; (ii) the purchase price and the expiration date for such
Excess Proceeds Offer (which shall be the date not less than 20 Business Days
from the date such notice is mailed) (the "Excess Proceeds Offer Expiration
Date"); (iii) that any Note not tendered will continue to accrue interest
pursuant to its terms; (iv) that, unless the Company defaults in the payment
of the Excess Proceeds Payment, any Note accepted for payment pursuant to the
Excess Proceeds Offer shall cease to accrue interest on and after the Excess
Proceeds Payment Date (as defined below); (v) that Holders electing to have a
Note purchased pursuant to the Excess Proceeds Offer will be required to
surrender the Note, together with the form entitled "Option of the Holder to
Elect Purchase" on the reverse side of the
Note completed, to the paying agent at the address specified in the notice
prior to the close of business on the Excess Proceeds Offer Expiration Date;
(vi) that Holders will be entitled to withdraw their election if the paying
agent receives, not later than the close of business on the Excess Proceeds
Offer Expiration Date, a facsimile transmission or letter setting forth the
name of such Holder, the principal amount of Notes delivered for purchase and
a statement that such Holder is withdrawing his election to have such Notes
purchased; and (vii) that Holders whose Notes are being purchased only in part
will be issued new Notes equal in principal amount to the unpurchased portion
of the Notes surrendered; provided that each Note purchased and each new Note
issued shall be in a principal amount of $1,000 or integral multiples thereof.
 
  On a date no more than four Business Days after the Excess Proceeds Offer
Expiration Date (the "Excess Proceeds Payment Date"), the Company will (i)
accept for payment on a pro rata basis Notes or portions thereof tendered
pursuant to the Excess Proceeds Offer; (ii) deposit with the paying agent
money sufficient to pay the purchase price of all Notes or portions thereof so
accepted; and (iii) deliver, or cause to be delivered, to the Trustee all
Notes or portions thereof so accepted together with an officers' certificate
specifying the Notes or portions thereof accepted for payment by the Company.
The paying agent shall promptly mail to the Holders of Notes so accepted
payment in an amount equal to the purchase price, and the Trustee shall
promptly authenticate and mail to such Holders a new Note equal in principal
amount to any unpurchased portion of the Note surrendered; provided that each
Note purchased and each new Note issued shall be in a principal amount of
$1,000 or integral multiples thereof. The Company will publicly announce the
results of the Excess Proceeds Offer as soon as practicable after the Excess
Proceeds Offer Expiration Date. For purposes of the "Limitation on Asset
Sales" covenant of the Indenture, the Trustee shall act as the paying agent.
 
  The Company will comply with Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable, in the event that such Excess Proceeds are
received by the Company under the "Limitation on Asset Sales" covenant of the
Indenture and the Company is required to repurchase Notes as described above.
 
 Limitation on Transactions with Shareholders and Affiliates
 
  The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction
(including, without limitation, the purchase, sale, lease or exchange of
property or assets, or the rendering of any service) with any holder (or any
Affiliate of such holder) of 5% or more of any class of Capital Stock of the
Company or with any Affiliate of the Company or any Restricted Subsidiary
(each, a "Related Party Transaction"), except upon fair and reasonable
economic terms no less favorable to the Company or such Restricted Subsidiary
than could be obtained, at the time of such transaction or at the time of the
execution of the agreement providing therefor, in a comparable arm's-length
transaction with a Person that is not such a holder or an Affiliate.
 
                                      79
<PAGE>
 
  In addition, and without limiting the foregoing, (i) any Related Party
Transaction or series of Related Party Transactions with an aggregate value in
excess of $5 million must first be approved by a majority of the Board of
Directors of the Company who are disinterested in the subject matter of the
transaction pursuant to a Board Resolution, and (ii) with respect to any
Related Party Transaction or series of Related Party Transactions with an
aggregate value in excess of $10 million, the Company must first obtain a
favorable written opinion from a nationally recognized investment banking firm
or nationally recognized independent accounting or consulting firm as to the
fairness from a financial point of view of such transaction to the Company or
such Subsidiary, as the case may be.
 
  The foregoing limitation does not limit, and shall not apply to (i) any
transaction between the Company and any of its Restricted Subsidiaries or
between Restricted Subsidiaries, (ii) the payment of reasonable and customary
regular fees to directors of the Company who are not employees of the Company,
(iii) any Restricted Payments not prohibited by the "Limitation on Restricted
Payments " covenant or (iv) transactions pursuant to Existing Affiliate
Agreements.
 
 Repurchase of Notes upon a Change of Control
 
  Upon the occurrence of a Change of Control, each Holder shall have the right
to require the repurchase of its Notes by the Company in cash pursuant to the
offer described below (the "Change of Control Offer") at a
purchase price equal to 101% of the principal amount thereof, plus accrued
interest (if any) to the date of purchase (the "Change of Control Payment").
Prior to the mailing of the notice to Holders provided for in the succeeding
paragraph, but in any event within 30 days following any Change of Control,
the Company covenants to (i) repay in full all indebtedness of the Company
that would prohibit the repurchase of the Notes as provided for in the
succeeding paragraph or (ii) obtain any requisite consents under instruments
governing any such indebtedness of the Company to permit the repurchase of the
Notes as provided for in the succeeding paragraph. The Company shall first
comply with the covenant in the preceding sentence before it shall be required
to repurchase Notes pursuant to the "Repurchase of Notes upon a Change of
Control" covenant of the Indenture.
 
  Within 30 days of the Change of Control, the Company shall mail a notice to
the Trustee and each Holder stating: (i) that a Change of Control has occurred
(and a brief description of the events resulting in such Change of Control),
that the Change of Control Offer is being made pursuant to the "Repurchase of
Notes upon a Change of Control" covenant of the Indenture and that all Notes
validly tendered will be accepted for payment; (ii) the purchase price and the
expiration date for such Change of Control Offer (which shall be the date not
less than 20 Business Days from the date such notice is mailed) (the "Change
of Control Offer Expiration Date"); (iii) that any Note not tendered will
continue to accrue interest pursuant to its terms; (iv) that, unless the
Company defaults in the payment of the Change of Control Payment, any Note
accepted for payment pursuant to the Change of Control Offer shall cease to
accrue interest on and after the Change of Control Payment Date (as defined
below); (v) that Holders electing to have any Note or portion thereof
purchased pursuant to the Change of Control Offer will be required to
surrender such Note, together with the form entitled "Option of the Holder to
Elect Purchase" on the reverse side of such Note completed, to the paying
agent at the address specified in the notice prior to the close of business on
the Change of Control Offer Expiration Date; (vi) that Holders will be
entitled to withdraw their election if the paying agent receives, not later
than the close of business on the Change of Control Offer Expiration Date, a
facsimile transmission or letter setting forth the name of such Holder, the
principal amount of Notes delivered for purchase and a statement that such
Holder is withdrawing his election to have such Notes purchased; and (vii)
that Holders whose Notes are being purchased only in part will be issued new
Notes equal in principal amount to the unpurchased portion of the Notes
surrendered; provided that each Note purchased and each new Note issued shall
be in a principal amount of $1,000 or integral multiples thereof.
 
  On a date no more than four business days after the Change of Control Offer
Expiration Date (the "Change of Control Payment Date"), the Company will: (i)
accept for payment Notes or portions thereof tendered pursuant to the Change
of Control Offer; (ii) deposit with the paying agent money sufficient to pay
the purchase price of all Notes or portions thereof so accepted; and (iii)
deliver, or cause to be delivered, to the Trustee, all
 
                                      80
<PAGE>
 
Notes or portions thereof so accepted together with an Officers' Certificate
specifying the Notes or portions thereof accepted for payment by the Company.
The paying agent shall promptly mail, to the Holders of Notes so accepted,
payment in an amount equal to the purchase price, and the Trustee shall
promptly authenticate and mail to such Holders a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered; provided that each
Note purchased and each new Note issued shall be in a principal amount of
$1,000 or integral multiples thereof. The Company will publicly announce the
results of the Change of Control Offer on or as soon as practicable after the
Change of Control Offer Expiration Date. For purposes of the "Repurchase of
Notes upon a Change of Control" covenant of the Indenture, the Trustee shall
act as paying agent.
 
  The Company will not be required to make a Change of Control Offer if a
third party makes an offer to purchase Notes in the manner, at the times and
otherwise in compliance with the requirements set forth in the Indenture
applicable to the Change of Control Offer to be made by the Company and
purchases all Notes validly tendered and not withdrawn under such offer to
purchase.
 
  The Company will comply with Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in the event that a Change of Control occurs and
the Company is required to repurchase the Notes under the "Repurchase of Notes
upon a Change of Control" covenant of the Indenture.
 
  If the Company is unable to repay all of its indebtedness that would
prohibit repurchase of the Notes or is unable to obtain the consents of the
holders of indebtedness, if any, of the Company outstanding at the time of a
Change of Control whose consent would be so required to permit the repurchase
of Notes, then the Company
will have breached the "Repurchase of Notes upon a Change of Control" covenant
of the Indenture. This breach will constitute an Event of Default under the
Indenture if it continues for a period of 60 consecutive days after written
notice is given to the Company by the Trustee or the Holders of at least 25%
in aggregate principal amount of the Notes outstanding. In addition, the
failure by the Company to repurchase Notes at the conclusion of the Change of
Control Offer will constitute an Event of Default without any waiting period
or notice requirements.
 
  There can be no assurances that the Company will have sufficient funds
available at the time of any Change of Control to make any debt payment
(including repurchases of Notes) required by the "Repurchase of Notes upon a
Change of Control" covenant of the Indenture (as well as may be contained in
other securities of the Company that might be outstanding at the time). The
"Repurchase of Notes upon a Change of Control" covenant of the Indenture will,
unless the consents referred to above are obtained, require the Company to
repay all indebtedness then outstanding that by its terms would prohibit such
Note repurchase, either prior to or concurrently with such Note repurchase.
The Credit Facility will prohibit the Company from purchasing the Notes except
in certain limited circumstances beginning in the year 2000 depending upon the
Company's amount of leverage.
 
LIMITATION OF APPLICABILITY OF CERTAIN COVENANTS IF NOTES RATED INVESTMENT
GRADE
 
  Notwithstanding the foregoing, the Company's and its Restricted
Subsidiaries' obligations to comply with the provisions of the Indenture
described above under the captions "--Certain Covenants--Limitation on
Indebtedness", "--Limitation on Restricted Payments", "--Limitation on Senior
Subordinated Indebtedness," "--Limitation on Dividend and Other Payment
Restrictions Affecting Restricted Subsidiaries", "--Limitation on the Issuance
of Capital Stock of Restricted Subsidiaries", "--Limitation on Asset Sales"
and "--Limitation on Transactions with Shareholders and Affiliates" will
terminate if and when the Notes are Investment Grade Rated; provided, however,
that the Company's and its Restricted Subsidiaries' obligations to comply with
such provisions shall be reinstated in the event the Notes are no longer
Investment Grade Rated, subject to the terms, conditions and obligations set
forth in the Indenture.
 
                                      81

  The Company shall not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its
property and assets (as an entirety or substantially an entirety in one
transaction or a series of related transactions) to, any Person nor permit any
Person to merge with or into the Company unless:
 
    (i) the Company shall be the continuing Person, or the Person (if other
  than the Company) formed by such consolidation or into which the Company is
  merged or that acquired or leased such property and assets of the Company
  shall be a corporation organized and validly existing under the laws of the
  United States of America or any jurisdiction thereof and shall expressly
  assume, by a supplemental indenture, executed and delivered to the Trustee,
  all of the obligations of the Company on all of the Notes and under the
  Indenture;
 
    (ii) immediately after giving effect to such transaction, no Default or
  Event of Default shall have occurred and be continuing;
 
    (iii) immediately after giving effect to such transaction on a pro forma
  basis, but not including the effect of any purchase accounting adjustments,
  the Company, or any Person becoming the successor obligor of the Notes
  shall have a Consolidated Net Worth at least equal to the Consolidated Net
  Worth of the Company immediately prior to such transactions, provided that
  this clause (iii) shall not apply to a consolidation or merger with or into
  a Wholly Owned Restricted Subsidiary with a positive net worth; provided
  that, in connection with any such merger or consolidation, no consideration
  (other than Common Stock in the surviving Person or the Company) shall be
  issued or distributed to the stockholders of the Company;
 
    (iv) immediately after giving effect to such transaction on a pro forma
  basis, the Company, or any Person becoming the successor obligor of the
  Notes could Incur at least $1.00 of Indebtedness under the first paragraph
  of the "Limitation on Indebtedness" covenant provided that this clause (iv)
  shall not apply to a consolidation or merger with or into a Wholly Owned
  Restricted Subsidiary with a positive net worth;
  provided that, in connection with any such merger or consolidation, no
  consideration (other than Common Stock in the surviving Person or the
  Company) shall be issued or distributed to the stockholders of the Company;
  and
 
    (v) the Company delivers to the Trustee an Officers' Certificate
  (attaching the arithmetic computations to demonstrate compliance with
  clauses (iii) and (iv) above) and Opinion of Counsel, in each case stating
  that such consolidation, merger or transfer and such supplemental indenture
  complies with this provision and that all conditions precedent provided for
  herein relating to such transaction have been complied with; provided that
  clauses (iii) and (iv) above do not apply if, in the good faith
  determination of the Board of Directors of the Company, whose determination
  shall be evidenced by a Board Resolution, the principal purpose of such
  transaction is to change the state of incorporation of the Company; and
  provided further that any such transaction shall not have as one of its
  purposes the evasion of the foregoing limitations.
 
SEC REPORTS
 
  The Indenture provides that whether or not the Company is then required to
file with the Commission information, documents or reports pursuant to Section
13 or Section 15(d) of the Exchange Act, the Company will file with the
Trustee and the Commission, in accordance with rules and regulations
prescribed from time to time by the Commission, such of the supplementary and
periodic information, documents and reports which would be required pursuant
to such sections if the Company were subject thereto.
 
EVENTS OF DEFAULT
 
  The following events will be defined as "Events of Default" in the
Indenture: (a) default in the payment of principal of, or premium, if any, on
any Note when the same becomes due and payable at maturity, upon acceleration,
redemption or otherwise; whether or not such payment is prohibited by the

<PAGE>
 
above under "--Ranking and Subordination"; (b) default in the payment of

covenant; (d) the Company or any Guarantor defaults in the performance of or
breaches any other covenant or agreement in the Indenture or under the Notes
(other than (a), (b) or (c) above) and such default or breach continues for a
period of 60 consecutive days after written notice by the Trustee or the
Holders of 25% or more in aggregate principal amount of the Notes; (e) there
occurs with respect to any issue or issues of Indebtedness of the Company or
any of its Significant Subsidiaries having an outstanding principal amount of
$25 million individually or $50 million in the aggregate for all such issues
of all such Persons, whether such Indebtedness now exists or shall hereafter
be created, (i) an event of default that has caused the holder thereof to
declare such Indebtedness to be due and payable prior to its Stated Maturity
and such Indebtedness has not been discharged in full or such acceleration has
not been rescinded or annulled within 60 days of such acceleration and/or (ii)
the failure to make a principal payment at the final (but not any interim)
fixed maturity and such defaulted payment shall not have been made, waived or
extended within 60 days of such payment default; (f) any final judgment or
order for the payment of money in excess of $25 million in the aggregate for
all such final judgments or orders against all such Persons shall be rendered
against the Company and/or any of its Significant Subsidiaries and shall not
be paid or discharged, and there shall be any period of 60 consecutive days
following entry of the final judgment or order that causes the aggregate
amount for all such final judgments or orders outstanding and not paid or
discharged or bonded against all such Persons to exceed $25 million (in excess
of amounts which the Company's insurance carriers have agreed to pay under
applicable policies) during which a stay of enforcement of such final judgment
or order, by reason of a pending appeal or otherwise, shall not be in effect;
(g) a court having jurisdiction in the premises enters a decree or order for
(A) relief in respect of the Company or any of its Significant Subsidiaries in
an involuntary case under any applicable bankruptcy, insolvency or other
similar law now or hereafter in effect, (B) appointment of a receiver,
liquidator, assignee, custodian, trustee, sequestrator or similar official of
the Company or any of its Significant Subsidiaries
or for all or substantially all of the property and assets of the Company or
any of its Significant Subsidiaries or (C) the winding up or liquidation of
the affairs of the Company or any of its Significant Subsidiaries and, in each
case, such decree or order shall remain unstayed and in effect for a period of
60 consecutive days; or (h) the Company or any of its Significant Subsidiaries
(A) commences a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consents to the entry of an
order for relief in an involuntary case under any such law, (B) consents to
the appointment of or taking possession by a receiver, liquidator, assignee,
custodian, trustee, sequestrator or similar official of the Company or any of
its Significant Subsidiaries or for all or substantially all of the property
and assets of the Company or any of its Significant Subsidiaries or (C)
effects any general assignment for the benefit of creditors.
 
  If an Event of Default (other than an Event of Default specified in clause
(g) or (h) above that occurs with respect to the Company) occurs and is
continuing under the Indenture, the Trustee or the Holders of at least 25% in
aggregate principal amount of the Notes then outstanding, by written notice to
the Company (and to the Trustee if such notice is given by the Holders (the
"Acceleration Notice")), may, and the Trustee at the request of such Holders
shall, declare the principal of, premium, if any, and accrued interest on the
Notes to be immediately due and payable. Upon a declaration of acceleration,
such principal of, premium, if any, and accrued interest shall be immediately
due and payable; provided, however, that if there are any amounts outstanding
under the Credit Agreement, such declaration shall not become effective until
the earlier of (i) an acceleration of the Indebtedness under the Credit
Agreement and (ii) 5 Business Days after receipt by the Company and the Bank
Agent of such Acceleration Notice. In the event of a declaration of
acceleration because an Event of Default set forth in clause (e) above has
occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default pursuant to clause (e) shall be remedied or cured by the
Company or the relevant Significant Subsidiary or waived by the holders of the
relevant Indebtedness within 60 days after the declaration of acceleration
with respect thereto. If an Event
 
                                      83
<PAGE>
 
of Default specified in clause (g) or (h) above occurs with respect to the
Company, the principal of, premium, if any, and accrued interest on the Notes
then outstanding shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.
The Holders of at least a majority in principal amount of the outstanding
Notes by written notice to the Company and to the Trustee, may waive all past
defaults and rescind and annul a declaration of acceleration and its
consequences if (i) all existing Events of Default, other than the nonpayment
of the principal of, premium, if any, and interest on the Notes that have
become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree
of a court of competent jurisdiction. For information as to the waiver of
defaults, see "--Modification and Waiver."
 
  The Holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith
may be unduly prejudicial to the rights of Holders of Notes not joining in the
giving of such direction and may take any other action it deems proper that is
not inconsistent with any such direction received from Holders of Notes. A
Holder may not pursue any remedy with respect to the Indenture or the Notes
unless: (i) the Holder gives the Trustee written notice of a continuing Event
of Default; (ii) the Holders of at least 25% in aggregate principal amount of
outstanding Notes make a written request to the Trustee to pursue the remedy;
(iii) such Holder or Holders offer the Trustee indemnity satisfactory to the
Trustee against any costs, liability or expense; (iv) the Trustee does not
comply with the request within 60 days after receipt of the request and the
offer of indemnity; and (v) during such 60-day period, the Holders of at least
a majority in aggregate principal amount of the outstanding Notes do not give
the Trustee a direction that is inconsistent with the request. However, such
limitations do not apply to the right of any Holder of a Note to receive
payment of the principal of, premium, if any, or interest on, such Note or to
bring suit for the enforcement of any such payment, on or after the due date
expressed in the Notes, which right shall not be impaired or affected without
the consent of the Holder.
 
  The Indenture will require certain officers of the Company to certify, on or
before a date not more than 90 days after the end of each fiscal year, that
they have conducted or supervised a review of the activities of the Company
and its Restricted Subsidiaries and the Company's and its Restricted
Subsidiaries' performance under the Indenture and that, to the best of such
officer's knowledge, based upon such review, the Company has fulfilled all
obligations thereunder or, if there has been a default in the fulfillment of
any such obligation, specifying each such default and the nature and status
thereof. The Company will also be obligated to notify the Trustee of any
default or defaults in the performance of any covenants or agreements under
the Indenture.
 
MODIFICATION AND WAIVER
 
  Modifications and amendments of the Indenture may be made by the Company,
the Guarantors and the Trustee with the consent of the Holders of not less
than a majority in aggregate principal amount of the outstanding Notes;
provided that no such modification or amendment may, without the consent of
each Holder affected thereby, (i) change the Stated Maturity of the principal
of, or any installment of interest on, any Note, (ii) reduce the principal
amount of, or premium, if any, or interest on, any Note, (iii) reduce any
amount payable on redemption of the Notes or upon the occurrence of an Event
of Default or reduce the Change of Control Payment or the Excess Proceeds
Offer Payment, (iv) change the place or currency of payment of principal of,
premium, if any, or interest on, any Note, (v) impair the right to institute
suit for the enforcement of any payment on or after the Stated Maturity (or,
in the case of a redemption, on or after the redemption date) of any Note,
(vi) reduce the above-stated percentage of outstanding Notes the consent of
whose Holders is necessary to modify or amend the Indenture, (vii) waive a
default in the payment of principal of, premium, if any, or interest on the
Notes, (viii) reduce the percentage or aggregate principal amount of
outstanding Notes the consent of whose Holders is necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults, (ix) modify or change any provision of the Indenture affecting the
ranking of the Notes or the Subsidiary
 
                                      84
<PAGE>
 
Guarantee in a manner adverse to the holders of the Notes or (x) release any
Guarantor from any of its obligations under its Subsidiary Guarantee or the
Indenture other than in accordance with the provisions of the Indenture, or
amend or modify any provision relating to such release.
 
  Neither the Company nor any of its Subsidiaries will, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise to any Holder of any notes for or as an inducement
to any consent, waiver or amendment of any of the terms or provisions of the
Indenture or the Notes unless such consideration is offered to be paid or
agreed to be paid to all Holders of the Notes that consent, waive or agree to
amend in the time frame set forth in the solicitation documents relating to
such consent, waiver or agreement.
 
DEFEASANCE
 
  Defeasance and Discharge. The Indenture will provide that the Company will

respect of the Notes (and any Guarantor will be discharged from any and all
obligations in respect of its Subsidiary Guarantee) on the 123rd day after the
deposit referred to below, and the provisions of the Indenture will no longer
be in effect with respect to the Notes and the Subsidiary Guarantees (except
for, among other matters, certain obligations to register the transfer or
exchange of the Notes, to replace stolen, lost or mutilated Notes, to maintain
paying agencies and to hold monies for payment in trust) if, among other
things, (A) the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and principal
in respect thereof in accordance with their terms
will provide money in an amount sufficient to pay the principal of, premium,
if any, and accrued interest on the Notes on the Stated Maturity of such
payments in accordance with the terms of the Indenture and the Notes, (B) the
Company has delivered to the Trustee (i) either (x) an Opinion of Counsel to
the effect that Holders will not recognize income, gain or loss for Federal
income tax purposes as a result of the Company's exercise of its option under
this "Defeasance" provision and will be subject to Federal income tax on the
same amount and in the same manner and at the same times as would have been
the case if such deposit, defeasance and discharge had not occurred, which
Opinion of Counsel must be based upon (and accompanied by a copy of) a ruling
of the Internal Revenue Service to the same effect unless there has been a
change in applicable Federal income tax law after the date of the Indenture
such that a ruling is no longer required or (y) a ruling directed to the
Trustee received from the Internal Revenue Service to the same effect as the
aforementioned Opinion of Counsel and (ii) an Opinion of Counsel to the effect
that the creation of the defeasance trust does not violate the Investment
Company Act of 1940 and after the passage of 123 days following the deposit,
the trust fund will not be subject to the effect of Section 547 of the United
States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law,
(C) immediately after giving effect to such deposit on a pro forma basis, no
Event of Default, or event that after the giving of notice or lapse of time or
both would become an Event of Default, shall have occurred and be continuing
on the date of such deposit or during the period ending on the 123rd day after
the date of such deposit, and such deposit shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company is a party or by which the Company is bound, and (D) if
at such time the Notes are listed on a national securities exchange, the
Company has delivered to the Trustee an Opinion of Counsel to the effect that
the Notes will not be delisted as a result of such deposit, defeasance and
discharge.
 
  Defeasance of Certain Covenants and Certain Events of Default. The Indenture
further will provide that the provisions of the Indenture will no longer be in
effect with respect to clauses (iii), (iv) and (v) under "--Consolidation,
Merger and Sale of Assets" and all the covenants described under "--Certain
Covenants," and clauses (c) and (d) under "--Events of Default" with respect
to such covenants shall be deemed not to be Events of Default, upon, among
other things, the deposit with the Trustee, in trust, of money and/or U.S.
Government Obligations that through the payment of interest and principal in
respect thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of, premium, if any, and accrued interest on
the Notes on the Stated Maturity of such payments in accordance with the terms
of the Indenture and the Notes, the satisfaction of the provisions described
in clauses (B)(ii), (C) and (D) of the preceding paragraph and the delivery by
the Company to the Trustee of an Opinion of Counsel to the effect that, among
other things,
 
                                      85
<PAGE>
 
the Holders will not recognize income, gain or loss for Federal income tax
purposes as a result of such deposit and defeasance of certain covenants and
Events of Default and will be subject to Federal income tax on the same amount
and in the same manner and at the same times as would have been the case if
such deposit and defeasance had not occurred.
 
  Defeasance and Certain Other Events of Default. In the event the Company
exercises its option to omit compliance with certain covenants and provisions
of the Indenture with respect to the Notes as described in the immediately
preceding paragraph and the Notes are declared due and payable because of the
occurrence of an Event of Default that remains applicable, the amount of money
and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Notes at the time of their Stated
Maturity but may not be sufficient to pay amounts due on the Notes at the time
of the acceleration resulting from such Event of Default. However, the Company
will remain liable for such payments.
 
NO PERSONAL LIABILITY OF INCORPORATORS, SHAREHOLDERS, OFFICERS, DIRECTORS, OR
EMPLOYEES
 
  The Indenture provides that no recourse for the payment of the principal of,
premium, if any, or interest on any of the Notes or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture, or in any
of the Notes or because of the creation of any Indebtedness represented
thereby, shall be had against any incorporator, shareholder, officer,
director, employee or controlling person of the Company or of any successor
Person thereof. Each Holder, by accepting the Notes, waives and releases all
such liability.
 
CONCERNING THE TRUSTEE
 
  The Indenture provides that, except during the continuance of a Default, the
Trustee will not be liable, except for the performance of such duties as are
specifically set forth in such Indenture. If an Event of Default has occurred
and is continuing, the Trustee will use the same degree of care and skill in
its exercise as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.
 
  The Indenture and provisions of the Trust Indenture Act of 1939, as amended,
incorporated by reference therein contain limitations on the rights of the
Trustee, should it become a creditor of the Company, to obtain payment of
claims in certain cases or to realize on certain property received by it in
respect of any such claims, as security or otherwise. The Trustee is permitted
to engage in other transactions; provided that if its acquires any conflicting
interest, it must eliminate such conflict or resign.
 
GOVERNING LAW
 
  The contractual rights and obligations of the Company and any Guarantor and
the rights of the holders of the Notes arising out of or in connection with
the Notes, including the obligation of the Company and any Guarantor to pay
all principal, interest and any other amounts payable under the Indenture and
the Notes, will be governed by, and shall be construed in accordance with, the
laws of the State of New York without giving effect to the conflict of laws
provisions thereof.
 
BOOK-ENTRY; DELIVERY AND FORM
 
  The Notes will be represented by one or more permanent global Notes in
definitive, fully registered form without interest coupons ("Global Notes")
and will be deposited with the Trustee as custodian for, and registered in the
name of, a nominee of DTC. Except in the limited circumstances described
below, owners of beneficial interests in a Global Note will not be entitled to
receive physical delivery of Certificated Notes (as defined below).
 
  Ownership of beneficial interests in a Global Note will be limited to
persons who have accounts with DTC ("participants") or persons who hold
interests through participants. Ownership of beneficial interests in a Global
 
                                      86
<PAGE>
 
Note will be shown on, and the transfer of that ownership will be effected
only through, records maintained by DTC or its nominee (with respect to
interests of participants) and the records of participants (with respect to
interests of persons other than participants).
 
  Investors also may hold their interests in a Note directly through Cedel
Bank, societe anonyme ("Cedel") or Morgan Guaranty Trust Company of New York,
Brussels office, as operator of the Euroclear system ("Euroclear"), if they
are participants in such systems, or indirectly through organizations that are
participants in such system. Cedel and Euroclear will hold interests in the
Notes on behalf of their participants through DTC.
 
  So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Notes represented by such Global Note for all
purposes under the Indenture and the Notes. No beneficial owner of an interest
in a Global Note will be able to transfer that interest except in accordance
with the applicable procedures of DTC, in addition to those provided for under
the Indenture and, if applicable, those of Euroclear and Cedel.
 
  Payments of the principal of, premium, if any, and interest on, a Global
Note will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. Neither the Company, the Trustee nor any paying agent under the
Indenture will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in a Global Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
  The Company expects that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, or interest in respect of a Global Note, will
credit participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests
in such Global Note held through such participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers registered in the names of
nominees for such customers. Such payments will be the responsibility of such
participants.
 
  Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds. Transfers
between participants in Euroclear and Cedel will be effected in the ordinary
way in accordance with their respective rules and operating procedures.
 
  The Company expects that DTC will take any action permitted to be taken by a
holder of Notes (including the presentation of Notes for exchange as described
below) only at the direction of one or more participants to whose account the
DTC interests in a Global Note is credited and only in respect of such portion
of the aggregate principal amount of Notes as to which such participant or
participants has or have given such direction. However, if there is an Event
of Default under the Notes, DTC will exchange the applicable Global Note for
Certificated Notes, which it will distribute to its participants.
 
  The Company understands that: DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants and facilitate the clearance and settlement
of securities transactions between participants through electronic book-entry
changes in accounts of its participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such
as banks, brokers, dealers and trust companies that clear through or maintain
a custodial relationship with a participant, either directly or indirectly
("indirect participants").
 
  Although DTC, Euroclear and Cedel are expected to follow the foregoing
procedures in order to facilitate transfers of interests in a Global Note
among participants of DTC, Euroclear and Cedel, they are under no
 
                                      87
<PAGE>
 
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. Neither the Company nor the
Trustee will have any responsibility for the performance by DTC, Euroclear or
Cedel or their respective participants or indirect participants of their
respective obligations under the rules and procedures governing their
operations.
 
  Interests in the Global Notes will be exchanged for Certificated Notes if
(i) DTC notifies the Company that it is unwilling or unable to continue as
depositary for the Global Notes, or DTC ceases to be a "Clearing Agency"
registered under the Exchange Act, and a successor depositary is not appointed
by the Company within 90 days, or (ii) an Event of Default has occurred and is
continuing with respect to the Notes and DTC requests that Certificated Notes
be issued. Upon the occurrence of any of the events described in the preceding
sentence, the Company will cause the appropriate Certificated Notes to be
delivered.

Underwriters to pay for and accept delivery of the Notes offered hereby are
subject to the approval of certain legal matters by their counsel and to
certain other conditions. The Underwriters are obligated to take and pay for
the entire aggregate principal amount of Notes offered hereby if any are
taken.
 
  The Underwriters propose to offer part of the Notes offered hereby directly
to the public at the public offering price set forth on the cover page hereof
and part to certain dealers at a price that represents a concession not in
excess of .25% of the principal amount of the Notes. Any Underwriter may
allow, and such dealers may reallow, a concession not in excess of .125% of
the principal amount of the Notes to other Underwriters or to certain other
dealers. After the Offering, the offering price and other selling terms may
from time to time be varied by the Underwriters.
 
  In order to facilitate the Offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Notes. Specifically, the Underwriters may over-allot in connection with the
Offering, creating a short position in the Notes for their own account. In
addition, to cover over-allotments or to stabilize the price of the Notes, the
Underwriters may bid for, and purchase, the Notes in the open market. Finally,
the underwriting syndicate may reclaim selling concessions allowed to an
Underwriter or a dealer for distributing the Notes in the Offering if the
syndicate repurchases previously distributed the Notes in transactions to
cover syndicate short positions, in stabilization transactions or otherwise.
Any of these activities may stabilize or maintain the market price of the
Notes above independent market levels. The Underwriters are not required to
engage in these activities and may end any of these activities at any time.

certain liabilities, including liabilities under the Securities Act.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors of ZD Inc.
 
In our opinion, the accompanying balance sheet presents fairly, in all
material respects, the financial position of ZD Inc. at March 27, 1998 in
conformity with generally accepted accounting principles. This balance sheet
is the responsibility of the Company's management; our responsibility is to
express an opinion on this balance sheet based on our audit. We conducted our
audit in accordance with generally accepted auditing standards which require
that we plan and perform the audit to obtain reasonable assurance about
whether the balance sheet is free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the balance sheet, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall balance sheet
presentation. We believe that our audit provides a reasonable basis for the
opinion expressed above.

                            NOTES TO BALANCE SHEET
 
1. ORGANIZATION
 
  ZD Inc. (the "Company") is a newly formed nonstock corporation incorporated
in the State of Delaware on February 4, 1998. Upon completion of the
reorganization discussed below, the Company will be a majority-owned indirect
subsidiary of SOFTBANK Corp. and affiliates ("Softbank"). The Company's
capital structure after the reorganization will consist of 10,000,000
authorized shares of $.01 par value preferred stock with no shares issued and
outstanding and 120,000,000 authorized shares of $.01 shares of common stock
with 74,200,000 shares issued and outstanding.
 
  The Company was formed to effect the reorganization of ZDI (Ziff-Davis Inc.)
and ZDCF (ZD COMDEX and Forums Inc.), both indirect wholly-owned subsidiaries
of Softbank. The reorganization is expected to be completed in the second
quarter of 1998 and will be accounted for in a manner similar to a pooling of
interests as the Company, ZDI and ZDCF will be companies under common control.
 
  There have been no operations of ZD Inc. as of March 27, 1998, and,
accordingly, statements of ZD Inc.'s operations and cash flows have not been
included herein.
 
2. FINANCING ARRANGEMENTS
 
  The Company expects to raise approximately $400,000,000 from the initial
public offering of its Common Stock, approximately $250,000,000 in notes, and
approximately $1,250,000,000 of senior bank debt. There can be no assurances
that the expected levels of financing from the Common Stock and Notes
Offerings will be obtained.
 
  The Company has obtained a commitment from a group of banks to enter into a
$1.35 billion Credit Facility. The Credit Facility will consist of a seven-
year $500 million reducing revolving credit facility (with $400 million drawn
at closing), a seven year $450 million term loan and an eight year $400
million term loan. The revolving credit will be available for loans, letters
of credit, and swing-line loans, subject to a certain maximum level of
borrowing. The revolving credit commitments will be reduced and the $450
million term loan will be amortized, beginning in September 2000, by (x) 10%
in 2000, in two equal quarterly installments, (y) 20% in each of 2001, 2002,
2003 and 2004 in four equal quarterly installments and (z) 10% at final
maturity in March 2005. The $400 million term loan will be amortized,
beginning in September 2000, by (x) $2 million in 2000 in two equal quarterly
installments, (y) $4 million in each of 2001, 2002, 2003, 2004 and 2005 in
four equal installments and (z) $378 million at final maturity in March 2006.
The Credit Agreement will also provide the Company the ability to increase the
revolving credit portion by $300 million to $800 million at any time prior to
June, 2000 if the banks agree to increase their commitments.
 
  Loans under both the revolving credit and term loan portions of the Credit
Facility will bear interest at either LIBOR plus an applicable margin or the
Alternate Base Rate plus an applicable margin. The applicable margin will be
based on a pricing grid to be determined by the Company's ratio of total debt
to EBITDA. The Company will also pay a commitment fee on the unused portion of
the revolving credit.
 
  The funds raised will be used to retire substantially all of the existing
notes payable to Softbank and its affiliates of ZDI and ZDCF, and for the
purchase of certain assets from affiliated companies.
 
3. EMPLOYEE BENEFIT PLANS
 
 1998 Incentive Compensation Plan
 
  The Company adopted the 1998 Incentive Compensation Plan (the "Plan") to
provide long-term incentives for its key employees and enhance shareholder
value. The Plan provides for the issuance of up to 8,500,000
 
                                      F-4
<PAGE>
 
options, stock appreciation rights, stock awards and other interests in the
Company's Common Stock. On February 13, 1998, the Company granted 5,254,700
options with an exercise price of $16.00 per share representing the fair value
of such options at that date. Such options vest ratably over five years.
 
 1998 Employee Stock Purchase Plan
 
  The Company has adopted the Employee Stock Purchase Plan (the "Stock
Purchase Plan") whereby eligible employees may purchase the Company's Common
Stock with after tax payroll deductions of 1% to 10% of their base pay. The
price at which shares of Common Stock will be purchased is the lesser of 85%
of the Fair Market Value of a share of Common Stock on (i) the first business
day of a purchase period or (ii) the last business day of a purchase period.
The Company has reserved 1.5 million shares of Common Stock for issuance under
the Stock Purchase Plan.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholder of Ziff-Davis Inc. and ZD COMDEX and
Forums Inc.
 
In our opinion, the accompanying combined balance sheets and the related
combined statements of operations, cash flows and changes in stockholder's
equity, present fairly, in all material respects, the financial position of
Ziff-Davis Inc. and ZD COMDEX and Forums Inc. and their subsidiaries (the
"Companies") at December 31, 1997 and 1996, and the results of Ziff-Davis
Inc.'s operations and cash flows for the period from February 29, 1996 to
December 31, 1996 and for the year ended December 31, 1997 and the results of
ZD COMDEX and Forums Inc.'s operations and cash flows for each of the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Companies' management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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, assessing

                    NOTES TO COMBINED FINANCIAL STATEMENTS
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
1. THE COMPANIES AND BASIS OF PRESENTATION
 
  The combined financial statements include the accounts of ZDI (Ziff-Davis
Inc.) and ZDCF (ZD COMDEX and Forums, Inc.) and their subsidiaries and
predecessor companies (collectively the "Companies"). The Companies are
wholly-owned indirect subsidiaries of SOFTBANK Corp. ("Softbank"), a Japanese
corporation which, as of December 31, 1997, was 50.2% owned by Mr. Son, its
President, including 43.4% directly owned by his 99% owned holding company,
MAC Inc. ( "MAC"), also a Japanese corporation.
 
  As further described below, the combined financial statements include the
accounts of COMDEX (formerly Softbank COMDEX, Inc.) and ZDI as of their
respective acquisition dates and Forums (formerly Softbank Forums Inc.) for
all periods presented. Effective December 31, 1997, COMDEX and Forums merged
and the surviving company was renamed ZD COMDEX and Forums Inc.
 
  The Companies operate in two business segments: (i) publishing and (ii)
trade shows and conferences.
 
 Publishing
 
  The publishing segment is engaged in publishing magazines, journals,
newsletters, electronic information products, training manuals and providing
market research about the computer industry. The publishing segment's
principal operations are in the United States and Europe, although it also
licenses or syndicates its editorial content to over 50 other publications
distributed worldwide.
 
 Trade shows and conferences
 
  The trade shows and conferences segment is engaged in the organization,
production and management of trade shows, conferences and seminars for the
computer industry. The trade shows and conferences segment's principal
operations are in the United States and to a lesser extent in Europe and Asia.
 
 Acquisition of ZDI (formerly Ziff-Davis Publishing Company and Ziff-Davis
Holdings Corp.)
 
  In February 1996, Softbank acquired the stock of Ziff-Davis Holdings Corp.
("Holdings") for an aggregate purchase price of approximately $1,800,000, plus
transaction costs. Concurrent with the acquisition, in a separate agreement,
MAC Inc., directly or through wholly-owned affiliates, acquired certain of the
assets and assumed certain of the liabilities of ZDI (the "MAC Assets") for an
aggregate purchase price of approximately $302,000.
 
  The acquisitions of ZDI by the Companies and the MAC Assets by MAC Inc. have
been accounted for as of February 29, 1996 using the purchase method of
accounting. The excess of the purchase price over the fair value of the assets
acquired and liabilities assumed was $1,922,000 and $285,000, respectively.
 
  Subsequent to the acquisition, Holdings and ZDI were merged with ZDI being
the surviving corporation.

  The pro forma results include amortization of intangible assets and interest
expense on debt assumed issued to finance the purchase. The pro forma results
are not necessarily indicative of what actually would have occurred if the
acquisition had been completed as of the beginning of the year, nor are they
necessarily indicative of future combined results.
 
 Purchase of MAC Assets
 
  In 1997, ZDI agreed to purchase certain of the MAC Assets for $370,000. The
acquisition will be effected in two tranches; the first of which closed on
October 31, 1997 and the second, which is subject to the successful completion
of an initial public offering of ZD Inc.'s Common Stock (refer to Note 18) or
upon a similar significant external financing. At December 31, 1997, ZDI has
accrued the $370,000 purchase price which has been recorded as a return of
capital.
 
  The acquisitions from MAC described above have been accounted for in a
manner similar to a pooling of interests as all entities involved are under
common control. Accordingly, the accompanying combined financial statements
include the results of operations of the MAC Assets from February 29, 1996.
Throughout these financial statements any reference to ZDI and ZDCF or the
Companies includes ZDI, ZDCF and the MAC Assets from February 29, 1996.
 
 Acquisition of Sendai
 
  On May 8, 1996, ZDI acquired substantially all of the assets and liabilities
of Sendai Publishing Group, Inc., a publisher and distributor of magazines,
books, products and computer services related to the electronic gaming
industry, for approximately $27,500, plus transaction costs. The acquisition
was accounted for as a purchase and accordingly, Sendai's results are included
in the combined financial statements since the date of acquisition. The excess
of the purchase price over assets acquired approximated $33,378. The
operations of Sendai did not have a material effect on the combined results of
operations for the year ended December 31, 1996.
 
 Acquisition of COMDEX
 
  Effective April 1, 1995, Softbank acquired the assets of the COMDEX trade
show business, now part of ZDCF, for approximately $803,000, plus transaction
costs. The acquisition has been accounted for as of April 1, 1995 using the
purchase method of accounting and accordingly COMDEX's results are included in
the combined financial statements since the date of acquisition. The excess of

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Combination
 
  The combined financial statements include the accounts of ZDI and ZDCF
including, as discussed above, the MAC Assets. All significant transactions
between these entities have been eliminated in combination.
 
  Investments in companies in which ownership interests range from 20 to 50
percent and the Companies have the ability to exercise significant influence
over the operating and financial policies of such companies are accounted for
under the equity method.
 
 Parent Company Financing
 
  As described in Note 18, Softbank announced a Reorganization and a financing
plan which includes a recapitalization of the Companies' debt and equity
structures. Prior to the consummation of the recapitalization transactions,
the Companies are dependent on funding from Softbank. At December 31, 1997,
the Companies had current liabilities which exceeded current assets by
$371,140. To the extent that the Companies are unable to fund their current
obligations as they become due from their operating cash flows, Softbank has
committed to provide additional financing or to restructure existing loan
arrangements at least through February 1999.
 
 Cash and cash equivalents
 
  The Companies consider all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
 Concentration of credit risk
 
  The Companies place its temporary cash investments with high credit quality
financial institutions. At times, such investments may be in excess of
federally insured limits. The Companies have not experienced losses in such
accounts.
 
  The Companies' advertisers and exhibitors include principally customers who
represent a variety of technology companies in the United States and other
countries. The Companies extend credit to their customers and distributors and
historically have not experienced significant losses relating to receivables
from individual customers or groups of customers.
 
 Property and equipment
 
  Property and equipment have been recorded at cost or their estimated fair
value at the date of acquisition. Depreciation is computed using the straight-
line method over the estimated useful lives of the assets which range from
three to thirty years. Leasehold improvements are amortized using the
straight-line method over the service life of the improvement or the life of
the related lease, whichever is shorter. Maintenance and repair costs are
charged to expense as incurred.
 
 Inventories
 
  Inventories, which consist principally of paper, are stated at the lower of
cost or market. Cost is determined on a first-in, first-out basis.
 
 Intangible assets
 
  Intangible assets consist principally of advertising lists, exhibitor
relationships, trademarks and trade names, and goodwill. Amortization of these
assets is computed on a straight-line basis over their estimated useful lives.
Identifiable

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
intangible assets are amortized over a period of 2 to 40 years and goodwill,
which represents the excess of the purchase price over the estimated fair
values of net assets acquired, is amortized over a period of 5 to 40 years
(refer to Note 5). The Companies assess the recoverability of their intangible
assets whenever adverse events or changes in circumstances indicate that
expected future cash flows (undiscounted and without interest charges) may not
be sufficient to support the carrying amount of intangible assets. If
undiscounted cash flows are not sufficient to support the recorded assets, an
impairment is recognized to reduce the carrying value of the intangibles to
estimated recoverable values. The Companies have not experienced any
impairment of its intangible assets.
 
 Revenue recognition
 
  Advertising revenue for the Companies' publications, less agency
commissions, is recognized as income in the month that the related
publications are sent to subscribers or become available for sale at
newsstands.
 
  Circulation revenue consists of both subscription revenue and single copy
newsstand sales. Subscription revenue, less estimated cancellations, is
deferred and recognized as income in the month that the related publications
are sent to subscribers. Newsstand sales, less estimated returns, are
recognized in the month that the related publications become available for
sale at newsstands.
 
  Payments received in advance of trade shows, conferences and seminars are
initially reported on the balance sheet as deferred revenue and are recognized
as income when the events take place.
 
  Revenue generated by market research is recognized when the service is
provided.
 
  On-line revenue, predominantly advertising, is recognized evenly over the
period of the related advertising contract which corresponds to the period of
time the advertising is displayed.
 
 Operating costs and expenses
 
  Cost of production includes the direct costs of producing magazines,
newsletters and training materials, primarily paper, printing and
distribution, and the direct costs associated with organizing, producing and
managing trade shows, seminars, conferences and expositions. Selling, general
and administrative costs include subscriber acquisition costs which are
expensed as incurred. Editorial and product development costs are expensed as
incurred. Product development costs include the cost of artwork, graphics,
prepress, plates and photography for new products.
 
 Foreign currency
 
  The effect of translating foreign currency financial statements into U.S.
dollars is included in the cumulative translation adjustments account in
stockholder's equity. Gains and losses on foreign currency transactions, which
are not significant to operations, have been included in selling, general and
administrative expenses. The Companies have not historically entered into
forward currency contracts.
 
 Other non-operating income
 
  Other non-operating income includes management fee income and the Companies'
equity share of income or loss from joint ventures.
 
 Income taxes
 
  The Companies use the asset and liability approach for financial accounting
and reporting of deferred taxes.

 Use of estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements.
Actual results may differ from these estimates.
 
 Fair value of financial instruments
 
  All current assets and liabilities are carried at cost, which approximates
fair value because of the short-term maturity of those instruments. The
recorded amounts of the Companies' long-term debt payable to affiliates also
approximate fair value based upon the current rates available to the Companies
for debt with similar remaining maturities.
 
 Stock-based compensation
 
  The Companies have elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees," to account for stock options.
Effective January 1, 1996, the Companies adopted the disclosure-only
provisions of Statement of Financial Accounting Standard ("SFAS") No. 123,
"Accounting for Stock-Based Compensation."
 
 Earnings per share
 
  Historical earnings per share data have been omitted on the basis that they
are not meaningful due to the insignificant number of shares outstanding.
 
 New Accounting Pronouncements
 
  SFAS No. 130, "Reporting Comprehensive Income," issued in June 1997, will
require the Companies to disclose, in financial statement format, all non-
owner changes in equity. Such changes include, for example, cumulative foreign
currency translation adjustments and unrealized gains and losses on securities
available for sale. This statement is effective for fiscal years beginning
after December 15, 1997 and requires presentation of prior period financial
statements for comparability purposes.
 
  SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," issued in June 1997, establishes standards for reporting
information about operating segments in annual financial statements and
interim financial reports. It also establishes standards for related
disclosures about products and services, geographic areas and major customers.
Generally, financial information will be required to be reported on the basis
that is used internally for evaluating segment performance and deciding how to
allocate resources to segments.
 
  SFAS No. 132, "Employer's Disclosure about Pensions and Other Post-
Retirement Benefits," is effective for the year ended December 31, 1998. This
standard revises the disclosure requirements for employers' pension and other
retiree benefits.
 
  The Companies expect to adopt the above statements beginning with their 1998
financial statements.

  Intangible assets primarily relate to the acquisitions of ZDI, COMDEX and
the MAC Assets. As discussed in Note 1, the acquisitions were accounted for
under the purchase method of accounting. As such, purchase price was allocated
to tangible and identifiable intangible assets with the remaining amount being
allocated to goodwill.
 
  Advertising lists, exhibitor relationships and subscriber lists were
recorded at their estimated fair value as determined by an income approach.
Trademarks/trade names were recorded at their estimated fair value using a
relief from royalty approach.
 
  All intangible assets are being amortized using the straight-line method
over their estimated useful lives, up to 40 years. In determining the
estimated useful lives, the Companies considered their competitive position in
the markets in which they operate, the historical attrition rates of
advertisers, subscribers and exhibitors, legal and contractual obligations,
and other factors.
 
  Recoverability of goodwill and intangible assets is assessed at a minimum on
an annual basis. Impairments would be recognized in operating results if a
permanent diminution in value were to occur based upon an undiscounted cash
flow analysis.

8. INCOME TAXES
 
  The Companies have been included in consolidated U.S. federal income tax
returns filed by Softbank, except for operations relating to the MAC Assets
(described in Note 1), which were assets of a separate taxpayer. The tax
expense reflected in the combined statements of operations and tax liabilities
reflected in the combined balance sheet have been prepared on a separate
return basis as though the Companies filed stand-alone income tax returns. No
tax benefit has been recorded for the losses related to the MAC Assets, as
such losses are not available to the Companies.
 
  The Companies and Softbank do not have a tax sharing agreement. Therefore,
no intercompany tax payments have been made and no related intercompany
receivable or payable has been recorded.
 
  Income (loss) before income taxes is attributable to the following
jurisdictions:

  The effective tax rate differs from the federal statutory tax rate primarily
as a result of the Companies' inability to deduct losses of the MAC Assets
prior to the effective date of the purchase. The amortization of nondeductible
goodwill resulted primarily from the stock acquisition of 100% of the stock of
ZDI in 1996.
 
  Following is a summary of the components of the deferred tax accounts at
December 31, 1996 and December 31, 1997:

</TABLE>
 
  As of December 31, 1996 and 1997 the Companies had total deferred tax assets
of $100,891 and $116,963, respectively, and total deferred tax liabilities of
$273,526 and $288,286, respectively. The December 31, 1996 and December 31,
1997 net deferred tax assets are reduced by a valuation allowance of $49,335
and $38,856, respectively, primarily relating to tax benefits of foreign net
operating loss carryforwards which are not expected to be realized. The
decrease in the valuation allowance in 1997 is primarily related to the
expiration of foreign net operating loss carryforwards. No deferred tax asset
has been established for the losses associated with the MAC Assets, which will
not be available to the Companies as a deduction.
 
  The Companies have U.S. and foreign net operating loss carryforwards of
approximately $286,322, which will begin to expire in 1998. The Companies'
utilization of certain net operating loss carryforwards, of approximately
$122,549, is subject to limitations, due to the change of ownership resulting
from the Softbank

acquisition of the ZDI stock on February 29, 1996. Management believes that
such limitations will not significantly affect the Companies' ability to
recognize the deferred tax assets relating to the carryforward. Accordingly,
no valuation allowance to reduce the deferred tax asset relating to the
carryforward has been established. In addition, the Companies have alternative
minimum tax credit carryforwards of $385 which may be carried forward
indefinitely until used.
 
  The Companies' foreign subsidiaries have no undistributed earnings for
remittance to the U.S. and, therefore, no U.S. or foreign tax provision on
remittances has been recorded.
 
9. DUE TO AFFILIATES AND MANAGEMENT
 
  The Companies are members of a group of companies affiliated through common
ownership with Softbank and has various transactions and relationships with
members of the group. Because of these relationships, it is possible that the
terms of those transactions are not the same as those that would result from
transactions among unrelated parties.

  See Note 18 for a discussion of the Companies' plan to restructure their
debt and equity structures.
 
  As part of the 1996 acquisition of ZDI, the Companies agreed to assume
certain obligations to management arising out of prior employment arrangements
with previous owners. In January 1997, the Companies paid all amounts due,
including accrued interest, through the payment date.
 
  Periodically, the Companies transfer excess cash to Softbank for cash
management purposes and in turn receive cash advances from Softbank to fund
the Companies' short-term working capital requirements. Interest is accrued
based on the net balance outstanding at the end of each month. Interest income
is earned at the 30-day LIBOR rate for the applicable month. Interest expense
is incurred at the 30-day LIBOR rate plus 0.5%.

 Other affiliated arrangements
 
  During the years ended December 31, 1996 and 1997, the Companies incurred
$2,000 and $1,631, advertising expense with Yahoo!, Inc. (Yahoo!), an
affiliated company. No advertising expense with Yahoo! was incurred in 1995.
 
  The Companies sell advertising space and exhibition services to Kingston
Technology Company ("Kingston"), an affiliated company. During the years ended
December 31, 1995, 1996 and 1997, the Companies recorded revenues of $0, $882
and $2,667, respectively, from sales to Kingston. These services were provided
under terms consistent with those provided to unaffiliated customers.
 
  ZDCF has entered into an agreement to manage certain trade shows and
expositions owned by Softbank and its affiliates, whereby ZDCF earns
management and licensing fees. The fees earned by ZDCF for the years ended
December 31, 1995, 1996 and 1997 were $1,979, $3,394 and $4,057, respectively.
 
  In 1996 and 1997, the Companies had an arrangement with SOFTBANK Interactive
Marketing ("SIM"), an affiliated company, for the provision of interactive
media sales. The Companies paid commissions to SIM of $600 and $1,800 during
the years ended December 31, 1996 and 1997, respectively. Effective December
31, 1997, SIM was acquired by an unrelated third party. Management believes
that the sale of SIM by Softbank will have no material impact on the
Companies.
 
  The Companies have an arrangement with SOFTBANK Services, an affiliated
company, whereby the Companies are charged for administrative services
provided plus a management fee. For the years ended December 31, 1995, 1996
and 1997, the Companies incurred services fees of $0, $359 and $1,259,
respectively, in relation to this agreement.
 
  ZDI has entered into certain licensing agreements with Softbank for the
publishing and distribution of Japanese language editions of certain
publications. The fees earned by ZDI for the years ended December 31, 1996 and
1997 were approximately $964 and $1,818, respectively, in each year.
 
  The Companies have entered into a license and services agreement with MAC to
develop ZDTV: Your Computer Channel. ZDTV is owned by MAC, but as part of this
license and services agreement MAC has granted the Companies an option
exercisable through December 31, 1998 to purchase all of MAC's interest in
ZDTV for an amount equal to MAC's investment plus 10% per annum. The Companies
are currently funding ZDTV's operations on behalf of MAC through unsecured
advances which, for approved levels of expenditure, are to be reimbursed by
MAC. Such advances bear interest at the 30-day LIBOR rate plus .50%. The
Companies' cumulative advances, which totaled $14.4 million net of $10.1
million in repayments through December 31, 1997, will be repaid concurrently
with the Reorganization (See Note 18). The Companies have not yet determined
whether they will exercise the option to purchase MAC's interest in ZDTV. Any
such purchase will depend upon access to sufficient cable carriage, which may
include entering into a joint venture or other co-ownership arrangement,
including an arrangement with a third party cable system operator which will
provide carriage and also assume a portion of the ongoing cash requirements on
terms that are acceptable to the Companies. ZDTV is not included in the
Companies' financial statements.
 
  If the Companies were to acquire a controlling interest in ZDTV from MAC,
such acquisition would be accounted for as a pooling transaction; if the
Companies were to acquire a non-controlling interest, such acquisition would
be accounted for under the equity method.
 
  ZDI has entered into operating leases for television production equipment
and has sublet such equipment to ZDTV, an affiliated company. The terms of the
subleases are substantially identical to the terms of the leases which provide
for annual lease payments totaling approximately $610 through 2003.

 Guarantee of Softbank's U.S. debt
 
  In April 1996, Softbank signed a line of credit agreement totaling $50,000
with an independent lender for which the Companies, along with certain other
Softbank affiliates, are guarantors. In January 1997 and October 1997, this
line of credit was increased to $75,000 and $150,000, respectively. At
December 31, 1997, $102,500 was outstanding under the line of credit.
 
 Return of capital and dividends
 
  On December 15, 1996, the Companies declared a return of capital of
approximately $900,000 paid through the issuance of a note payable to a
subsidiary of Softbank and a cash dividend of $8,000 to Softbank. In 1997, the
Companies recorded a return of capital of $381,434 in connection with the

10. EMPLOYEE STOCK COMPENSATION PLANS
 
 Executive stock option plan
 
  The SOFTBANK 1996 and 1997 Executive Stock Option Plans provide for the
granting of nonqualified stock options to purchase the common stock of
Softbank to officers, directors and key employees of the Companies. Under the
plans, options have been granted at exercise prices equal to the closing
market price in Japan's public equities market (market price denominated in
Japanese yen) on the date of grant. As of December 31, 1997, substantially all
options granted become exercisable in various installments over the first six
anniversaries of the date of grant and expire ten years after the date of
grant.
 
  Information relating to stock options during 1995, 1996 and 1997 is as

(1) The exercise price of the stock options is set in Japanese yen. The
    exercise prices as shown above have been converted to U.S. dollars based
    upon the exchange rate as of the date of grant for the respective options.
(2) Adjusted for a 1.4:1 stock split during 1996 and a 1.3:1 stock split
    during 1997.
 
  As permitted by SFAS 123, the Companies have chosen to continue to account
for stock options in accordance with the provisions of APB 25 and,
accordingly, no compensation expense related to stock option grants was
recorded in 1996 or 1997. Pro forma information regarding net income is
required by SFAS 123 and has been determined as if the Companies had accounted
for stock options under the fair value method. The fair value of the option
grants was estimated at the date of grant using the Black Scholes option-
pricing model with the following assumptions for 1996 and 1997:

  The weighted average fair value of options granted in 1996 and 1997 was
$64.30 and $34.05, respectively. For purposes of the pro forma disclosures,
the estimated fair value of the options is amortized to expense over

the options' vesting period. Had compensation cost for the stock option plans
been determined based upon the fair value at the grant date for awards during
1996 and 1997, consistent with the provisions of SFAS 123, the Companies' net
loss would have been increased by approximately $3,100 and $4,200,
respectively. On January 23, 1998, the exercise price of all of the shares
outstanding under option agreements were reset to an exercise price equal to
the closing market price on Japan's Tokyo Stock Exchange First Section at that
date. In conjunction with the repricing, those options previously exercisable
on December 31, 1997 may now be exercised only after July 19, 1998. Repricing
of the stock options will not result in compensation expense to the Companies.
 
 Other stock compensation plans
 
  During 1996 and 1997, the Company granted 45,760 and 61,940 shares of common
stock of Softbank, respectively, (adjusted for two 1.4:1 stock splits during
1996 and a 1.3:1 stock split during 1997) to certain key employees, subject to
restrictions as to continuous employment which expire over a three to five-
year period from the date of grant. The granting of the shares to the
Companies' employees has been recorded as additional paid-in capital offset by
a reduction to stockholder's equity as deferred compensation. Such amounts
were recorded at the fair value, as established by market price of the shares
on the date of grant. The unearned compensation is being amortized ratably
over the restricted periods. During 1996, restrictions on 13,790 shares
expired, 2,160 shares were forfeited and $1,080 was charged to expense related
to the restricted stock awards. During 1997, restrictions on 75,210 shares
expired, 2,150 shares were forfeited and $3,916 was charged to expense related
to these restricted stock awards.
 
11. EMPLOYEE BENEFIT PLANS
 
 Pension plan
 
  Certain employees of ZDCF who have met eligibility requirements are covered
by a noncontributory defined benefit pension plan. The benefits are based on
years of service and average compensation at the time of retirement. The
Companies' funding policy is to contribute amounts sufficient to meet the
minimum funding requirements as set forth in the Employee Retirement Income
Security Act of 1974 ("ERISA"). Contributions to the plan are determined in
accordance with the projected unit credit cost method. Plan assets consist of
U.S. equity securities, high grade corporate bonds and commercial paper, and
U.S. treasury notes.
 
  The weighted average assumed discount rate of 7% and rate of increase in
future compensation levels of 6% was used in the determination of the
actuarial present value of the projected benefit obligation at December 31,
1996 and 1997. The weighted average expected long-term rate of return on plan
assets at December 31, 1996 and 1997 was 7%.
 
  Net periodic pension cost includes the following components:

</TABLE>
 
  During 1997, the Companies decided to terminate the defined benefit pension
plan and pursuant to this decision, all accrued benefits became fully vested
as of August 31, 1997. The above amounts reflect the effects of such
termination. All accrued plan obligations will be settled during 1998. There
was no significant gain or loss recognized in connection with the termination.
Any gain or loss associated with the plan settlement will be recognized in
1998.
 
 Retirement plans
 
  The Companies maintain various defined contribution retirement plans.
Substantially all of the Companies' employees are eligible to participate in
one of the plans under which annual contributions may be made by the Companies
for the benefit of all eligible employees. In certain cases, employees may
also make contributions to the plan in which they participate which, and
subject to certain limitations, may be matched by the Companies up to certain
specified percentages. Employees are generally eligible to participate in a
plan upon joining the Companies and receive matching contributions after one
year of employment. The Companies made contributions to the plans totaling
$2,115, $10,470 and $13,725 in 1995, 1996 and 1997, respectively.

18. SUBSEQUENT EVENTS (UNAUDITED)
 
 Reorganization of the Companies
 
  In February 1998, Softbank announced a reorganization of the Companies (the
"Reorganization"). In connection with the Reorganization, Softbank will
contribute the common stock of ZDI and ZDCF to a newly formed company in
exchange for a majority of the new company's common stock, the balance of
which will be offered to the public. In addition, approximately $929 million
of obligations owed to Softbank will be converted to equity, approximately
$1.5 billion of notes payable to affiliates will be refinanced, the $370
million obligation for the purchase of the MAC Assets will be paid and
balances totaling approximately $42 million due from MAC will be settled. The
Reorganization is contingent upon the successful completion of the public
stock offering and refinancing of the notes payable to affiliates.
 
 Guarantee of Softbank's U.S. Debt
 
  In March 1998, the Company increased its guarantee of Softbank's U.S. debt
from $150 million to $450 million.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholder of
Ziff-Davis Inc., (formerly Ziff-Davis Publishing Company)
 
In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, cash flows and changes in stockholder's
equity, present fairly, in all material respects, the financial position of
Ziff-Davis Inc. and its subsidiaries (formerly Ziff-Davis Publishing Company
or the "Company") at December 31, 1995 and February 28, 1996, and the results
of their operations and their cash flows for the year ended December 31, 1995
and for the period from January 1, 1996 to February 28, 1996, in conformity
with generally accepted accounting principles. 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 of these statements in accordance with generally accepted
auditing standards which 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, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.
 
As discussed in Note 16 to the financial statements, the Company was acquired
by SOFTBANK Holdings Inc. on February 29, 1996.

           (A WHOLLY-OWNED SUBSIDIARY OF ZIFF-DAVIS HOLDINGS CORP.)
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
1. ORGANIZATION AND ACQUISITION
 
  Ziff-Davis Inc. ("ZDI," formerly Ziff-Davis Publishing Company) is a wholly-
owned subsidiary of Ziff-Davis Holdings Corp. ("Holdings").
 
  ZDI is engaged in publishing magazines, journals and training manuals and
providing market research about the computer industry, with operations in the
United States, Canada and Europe.
 
 Acquisition
 
  Effective January 1, 1995, Holdings, through ZDI, directly and indirectly
acquired certain assets and assumed certain liabilities of the Ziff-Davis
publishing business and related businesses (the "Acquisition" or the "Acquired
Businesses") from Ziff Communications Company, L.P., a limited partnership
("ZCC") and other persons and entities (collectively referred to as the
"Sellers"), for an aggregate purchase price of approximately $1,400,000 plus
transaction costs. ZDI funded the Acquisition through the issuance of Common
Stock, bank borrowings and a subordinated note payable to Holdings.
 
  The acquisition has been accounted for using the purchase method of
accounting.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of ZDI and its
subsidiaries. All significant intercompany accounts and transactions have been
eliminated in consolidation.
 
  Investments in companies in which ownership interests range from 20 to 50
percent are accounted for under the equity method. ZDI has an equity
investment interest in Family PC G.P. of 50%. The equity investment in Family
PC G.P. is not material to ZDI's consolidated financial statements.
 
 Cash and cash equivalents
 
  ZDI considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents.
 
 Concentration of credit risk
 
  ZDI places its temporary cash investments with high credit quality financial
institutions. At times, such investments may be in excess of federally insured
limits. ZDI has not experienced losses in such accounts.
 
  ZDI's advertisers include customers who represent a variety of technology
companies in the United States and other countries. ZDI extends credit to its
customers and historically has not experienced significant losses relating to
receivables from individual customers or groups of customers.
 
 Property and equipment
 
  Property and equipment have been recorded at their estimated fair value at
the date of acquisition. Depreciation is computed using the straight-line
method over the estimated useful lives of the acquired assets, ranging from 3
to 39 years. Leasehold improvements are amortized using the straight-line
method over the service life of the improvement or the life of the related
lease, whichever is shorter. Maintenance and repair costs are charged to
expense as incurred.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
              (IN THOUSANDS, EXCEPT PER SHARE AND SHARE AMOUNTS)
 
 Paper inventories
 
  Paper inventories are stated at the lower of cost or market. Cost is
determined on a first-in, first-out basis.
 
 Intangible assets
 
  Intangible assets consist principally of advertising lists, trademarks and
trade names and goodwill. Amortization of these assets is computed on a
straight-line basis over their estimated useful lives. Identifiable intangible
assets are amortized over a period of 2 to 39 years and goodwill, which
represents the excess of the purchase price over the estimated fair values of
net assets acquired, is amortized over 40 years. ZDI assesses the
recoverability of its intangible assets whenever adverse events or changes in
circumstances indicate that expected future cash flows (undiscounted and
without interest charges) may not be sufficient to support the carrying amount
of intangible assets. If undiscounted cash flows are not sufficient to support
the recorded assets, an impairment loss is recognized to reduce the carrying
value of the intangibles to its estimated recoverable value.
 
 Revenue recognition
 
  Advertising revenue for ZDI's publications, less agency commissions, is
recognized as income in the month that the related publications are sent to
subscribers or becomes available for sale at newsstands.
 
  Circulation revenue consists of both subscription and single copy newsstand
sales. Subscription revenue, less estimated cancellations, is deferred and
recognized as income in the month that the related publications are sent to
subscribers. Newsstand sales, less estimated returns, are recognized in the
month that the related publications become available for sale at newsstands.
 
  Revenue generated by market research is recognized when the service is
provided.
 
 Operating costs and expenses
 
  Cost of production includes paper, manufacturing, distribution and
fulfillment. Selling and promotion costs include subscriber acquisition costs
which are expensed as incurred. Editorial and product development costs are
generally expensed as incurred. Product development costs include the cost of
artwork, graphics, prepress, plates and photography for new products.
 
 Foreign currency
 
  Gains and losses on foreign currency transactions, which are not
significant, have been included in selling, general and administrative
expenses. The effect of translation of foreign currency financial statements
into U.S. dollars is included in the cumulative translation adjustments
account in stockholder's equity.
 
 Income taxes
 
  ZDI uses the asset and liability approach for financial accounting and
reporting of deferred taxes.
 
 Use of estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements.
Actual results may differ from these estimates.

 Fair value of financial instruments
 
  All current assets and liabilities are carried at cost, which approximates
fair value because of the short-term maturity of those instruments. The
recorded amounts of ZDI's long-term debt also approximate fair value which was
based upon the current rates available to ZDI for debt with similar remaining
maturities.
 
 Impairment of long-lived assets
 
  In 1995, the Financial Accounting Standards Board issued SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to be Disposed Of" ("SFAS 121"). ZDI adopted SFAS 121 in fiscal 1996 with no
effect on operations.
 
 Earnings per share
 
  Historical earnings per share data has been omitted on the basis that it is
not meaningful due to the insignificant number of shares outstanding.

</TABLE>
 
  Intangible assets primarily relate to the acquisition of ZDI. As discussed
in Note 1, the acquisition was accounted for under the purchase method of
accounting. As such the purchase price was allocated to tangible and
identifiable intangible assets with the remaining amount allocated to
goodwill.
 
  Advertising lists, exhibitor relationships and subscriber lists were
recorded at their estimated fair value as determined by an "income" approach.
Trademarks/trade names were recorded at their estimated fair value using a
"relief from royalty" approach.
 
  All intangible assets are being amortized using the straight-line method
over their estimated useful lives, up to 40 years. In determining the
estimated useful lives, ZDI considered its competitive position in the markets
in which it operates, the historical attrition rates of advertisers,
exhibitors and subscribers, legal and contractual obligations, and other
factors.
 
  Recoverability of goodwill and intangible assets is assessed at a minimum on
an annual basis. Impairments would be recognized in operating results if a
permanent diminution in value were to occur based upon an undiscounted cash
flow analysis.

assets of $83,176 and $86,243, respectively, and total deferred tax
liabilities of $72,869 and $73,488, respectively.
 
  As of February 28, 1996, ZDI has U.S. and foreign net operating loss
carryforwards of approximately $244,172, which will begin to expire on
December 31, 1996. The December 31, 1995 and the February 28, 1996 net
deferred tax asset is reduced by a valuation allowance of $47,176 relating to
tax benefits of foreign net operating loss carryforwards which are not
expected to be recognized.
 
  ZDI's foreign subsidiaries have no undistributed earnings for remittance to
the U.S. and therefore no U.S. or foreign tax provision on remittances has
been recorded.

</TABLE>
 
  On December 21, 1994, ZDI borrowed $515,000 under the terms of a Credit
Agreement. The proceeds of the loan were used to finance a portion of the
Acquisition and pay certain transaction costs.
 
  Tranche A, as amended on August 31, 1995, is a six-year term loan due
quarterly in varying amounts from September 30, 1995 through December 31,
2000. Tranche B is a seven-year term loan due quarterly in varying amounts
commencing September 30, 1995 through September 30, 2001, with a final payment
of $126,000 on December 31, 2001. Tranche C is an eight-year term loan
providing for quarterly payments, aggregating $1,000 per calendar year
commencing September 30, 1995 through December 31, 2001, followed by four
quarterly payments of $39,500 through December 31, 2002.
 
  The Credit Agreement also provides ZDI with an additional $85,000, increased
to $150,000 under terms of the August 31, 1995 amendment, under a revolving
credit arrangement through December 31, 2000. These funds are available for
loans, letters of credit, and swing-line loans, subject to certain maximum
levels of borrowing. At least once during each year, for a period of 30
consecutive days, the loans outstanding under the revolving credit facility
must be reduced so that the aggregate outstanding amount does not exceed
$130,000 during such 30-day period. The commitment fee for the revolving
credit facility is .50% during 1995 and 1996 on the unused portion of the
facility. ZDI has the option to permanently reduce the amount available for
borrowings under the revolving credit facility by a minimum of $5,000 at any
time. At December 31, 1995 and February 28, 1996, $130,000 under the revolving
credit facility is available for borrowing.
 
  During 1995 and the period January 1, 1996 to February 28, 1996, the Tranche
A and revolving credit loans bore interest, payable at least quarterly, at
either the Average Bank Rate ("ABR"), as defined, plus 1.25%, or at the
Eurodollar rate, plus 2.5% at the election of ZDI. Tranche B and C loans bore
interest, payable at least quarterly, at either the ABR, plus 1.75% and 2.25%,
respectively, or at the Eurodollar rate, as defined, plus 3% and 3.5%,
respectively, at the election of ZDI. Swing-line loans bear interest at the
ABR, plus the applicable margins as discussed above. Borrowings outstanding at
December 31, 1995 and February 28, 1996 were $446,000 and the weighted average
interest rate was 8.8% and 10.1%, respectively.

  ZDI is required to comply with various restrictive covenants, including
maintaining certain financial ratios, restrictions on additional indebtedness,
capital expenditures, acquisitions, certain asset sales, declaration of
dividends and acquisition of ZDI's or Holdings' Common Stock. All borrowings
under the Credit Agreement are secured by the common stock and other equity
interests of ZDI and its wholly-owned subsidiaries.
 
  ZDI is required to make mandatory prepayments of the loans with the net
proceeds of certain asset sales and debt issuances, if any. ZDI is also
required, commencing with the year ending December 31, 1995, to prepay the
loans with a portion of excess cash flow, as defined, once certain cash
balances are achieved. These cash balances were not achieved during 1995 or
for the period from January 1, 1996 to February 28, 1996 and therefore no
prepayments occurred.
 
  Scheduled principal payments for each of the next five years are as follows:

10. RELATED PARTY TRANSACTIONS
 
  Prior to the Acquisition, ZCC provided certain services to ZDI, including
legal, tax, human resources, payroll, facilities management and management
information services. The remaining unpaid balance (approximately $8,100) for
such services was paid in the normal course of business during 1995. Beginning
in 1995, ZDI sublet office space and provided administrative services to ZCC.
Such office space and services were provided to ZCC at ZDI's cost. The
majority partners of ZCC have a continuing investment in Holdings of
approximately 6%.
 
  On the closing date of the Acquisition, ZDI paid approximately $280,000 in
cash to the Sellers and issued notes due January 13, 1995 and January 16, 1995
totaling $1,033,931, for the balance. These notes were subsequently fully paid
in January, 1995.
 
  See Note 11 for a description of subordinated debentures.
 
  In connection with the Acquisition, ZDI paid transaction costs of $14,000 to
an affiliate of Holdings.
 
  The Company paid $44,555 and $3,791 in interest to Holdings for the year
ended December 31, 1995 and for the period from January 1, 1996 to February
28, 1996, respectively.
 
11. SUBORDINATED DEBENTURES--RELATED PARTY
 
  On December 21, 1994, ZDI issued a $525,000 subordinated note payable to
Holdings to finance a portion of the Acquisition. The note bears interest at 8
1/2% per annum with interest payable semiannually on February 28 and August 31
of each year. The principal is repayable in three installments of $175,000
each on December 21, 2005, December 21, 2006 and December 21, 2007. This note
is fully subordinated in right of payment to the bank borrowings (see Note 9).

benefit of all eligible employees. Employees may also make contributions to
the plan in which they participate which, subject to certain limitations, may
be matched by ZDI up to certain specified percentages. Employees are generally
eligible to participate in a plan upon joining ZDI and receive matching
contributions immediately upon commencement of employment. In addition, the
employees become eligible to receive a discretionary Company contribution
after one year of employment. ZDI made contributions of $8,432 and $1,407 for
