                                    SUMMARY

  This summary highlights key aspects of the offering of ZDNet stock contained
elsewhere in this prospectus. This summary is not a substitute for the more
detailed information contained in the rest of this prospectus. For a more
comprehensive description of the offering of ZDNet stock, you should read the
entire prospectus.

                           ZIFF-DAVIS INC. AND ZDNET

Ziff-Davis Inc.

  Ziff-Davis Inc. is a leading media and marketing company that provides
information on computing and technology, including the Internet. We provide
technology companies worldwide with marketing strategies for reaching key
decision-makers. From an accounting standpoint, we have separated ZDNet, our
online business division, from ZD, which includes the rest of our businesses
and a retained interest in ZDNet. We have allocated all of our consolidated
assets, liabilities, revenue, expenses and cash flow between ZDNet and ZD.

  We intend our ZDNet stock to track the performance of ZDNet and we intend our
ZD stock to track the performance of ZD. We are offering you shares of ZDNet
stock but we are not offering you any shares of ZD stock. We briefly describe
ZD below and we briefly describe ZDNet in the next section of this summary.

  ZD includes:

  . The following Ziff-Davis Inc. businesses: print publishing, trade shows
    and conferences, market research, education, including our Internet-based
    educational service, and television, including an online component.

  . A retained interest in ZDNet. This retained interest is currently 100%,
    but will decline to reflect the initial issuance of ZDNet stock as well
    as any future issuances.

  Our principal executive offices are located at One Park Avenue, New York, New
York 10016. Our telephone number is (212) 503-3500.

ZDNet

  We are offering you ZDNet stock, which we intend to track the performance of
ZDNet, our online business division.

  ZDNet provides technology-related information to Internet users worldwide.
ZDNet focuses on content, community and commerce. ZDNet creates up-to-date,
reliable and comprehensive content divided broadly into "channels" that focus
on specific topics or audience groups. ZDNet's network of over 60
interconnected Internet sites offers over 1,200

                                       3
<PAGE>

news stories per month, 50,000 product listings, 30,000 product reviews and
34,000 downloadable programs. The community of ZDNet users interacts through
various online message systems, including bulletin boards, chat rooms,
moderated forums and e-mail. ZDNet facilitates commerce by providing users of
its sites with the ability to evaluate, compare and purchase products and
services and by providing advertisers and merchants with access to a highly
targeted user group with attractive demographics.

  According to Media Metrix, in December 1998 zdnet.com ranked first among all
Web sites in the category of news, information and entertainment, ahead of such
sites as cnet.com, cnn.com, msnbc.com, Disney Online and espn.com. ZDNet
estimates that its Web sites served more than 202 million page views during
December 1998, up from 124 million in December 1997. ZDNet delivered
approximately 460 million ad-bearing pages during the fourth quarter of 1998,
up from 240 million during the same period of 1997. In addition, ZDNet had
localized foreign language editions in more than 16 countries as of December
31, 1998.

  As the Internet gains acceptance as an advertising and commerce medium and as
Internet use continues to grow, technology will play an increasing role in
everyday life. According to Dataquest, worldwide end user spending for
information technology products and related services is expected to be
approximately $2 trillion in 1999 and grow 10% to 15% annually over the next
three years. The prevalence of technology and the growing number of
technological choices heighten the demand for up-to-date, comprehensive
information about technology-related products and services.

  ZDNet's objective is to be the leading online content site focused on
technology products and services and the preferred online platform for
advertisers and merchants. ZDNet's strategy is to:

  . continue to offer differentiated technology-related content,

  . grow ZDNet's user community,

  . build ZDNet's brand strength,

  . increase advertising and commerce revenue,

  . strengthen and expand strategic alliances and

  . extend ZDNet's international presence.

  ZDNet derives many benefits from its relationship with ZD, including consumer
and business recognition of the ZD brand name, use of magazine articles,
product reviews and other information created by ZD, and the ability to market
and promote ZDNet across all of ZD's businesses and publications. ZDNet's
revenue has grown from $13.6 million in 1995 to $56.1 million in 1998.

                              What is Tracking Stock?

ZDNet Stock:                  ZDNet stock is what is sometimes referred to as
                              tracking stock. Tracking stock is a type of
                              common stock that is intended to reflect or track
                              the performance of a particular business. In this
                              case, ZDNet stock is intended to track the
                              performance of ZDNet.

                              From an accounting standpoint, we have separated
                              ZDNet, our online business division, from ZD,
                              which includes the rest of our businesses and a
                              retained interest in ZDNet, and we have allocated
                              all of our consolidated assets, liabilities,
                              revenue, expenses and cash flow between ZDNet and
                              ZD.

                              Although we intend ZDNet stock to reflect the
                              performance of ZDNet, holders of ZDNet stock will
                              be common stockholders of Ziff-Davis Inc. For
                              this reason, holders of ZDNet stock will be
                              subject to all of the risks associated with an
                              investment in Ziff-Davis Inc. and all of its
                              businesses, assets and liabilities.

Dividends:                    We currently intend to retain all of our earnings
                              to finance our operations, repay our indebtedness
                              and fund future growth. We do not expect to pay

                              we will value ZD stock and ZDNet stock based on

       Summary Historical and Pro Forma Combined Financial and Other Data

  The following table presents summary historical combined data for ZDNet as of
and for the ten month period ended December 31, 1996 and as of and for the
years ended December 31, 1997 and 1998. In addition, the table presents
unaudited summary pro forma data as of and for the year ended December 31,
1998. The historical financial data was derived from the Combined Financial
Statements of ZDNet included in this prospectus. An affiliate of Ziff-Davis
Inc. acquired ZDNet on February 29, 1996; therefore, no results of ZDNet are
shown for periods before that date. No historical earnings per share or share
data is presented as Ziff-Davis Inc. does not consider such data to be
meaningful. After the issuance of ZDNet stock, Ziff-Davis Inc. will report
earnings per share data for ZD and ZDNet but not for Ziff-Davis Inc.

  The pro forma data presented in the table below assumes that:

  . the following transactions had occurred as of January 1, 1998 in the case
   of statement of operations data and other data and as of December 31, 1998
   in the case of balance sheet data:

   (a) the sale of 10,000,000 shares of ZDNet stock in the offering at a
       public offering price of $19.00 per share, less underwriting discounts
       and estimated expenses of the offering assumed to be $1.75 per share,

   (b) the attribution to ZDNet of the assumed net proceeds from 1,500,000
       shares and the attribution to ZD of the remaining net proceeds from
       the offering, and

   (c) the transfer by ZDNet to ZD, as an inter-group revolving credit
       advance, bearing interest at an assumed rate of 8.5% of the net
       proceeds attributed to ZDNet and

   (d) the recording of non-cash compensation expense relating to ZDNet
       options.

  . the policies described under "Certain Cash Management and Accounting
   Policies" included in this prospectus had been adhered to for the year
   ended December 31, 1998, and each cash transfer from ZD to ZDNet or from
   ZDNet to ZD had been accounted for as a decrease or increase in the inter-
   group revolving credit advance referred to in (c) above as contemplated by
   those policies.

  The pro forma data is not necessarily indicative of the actual financial
position or results of operations of ZDNet as of or for the year ended December
31, 1998 or the financial position or results of operations that ZDNet would
have experienced if the transactions for which the data gives pro forma effect
had in fact occurred at the times assumed. Also, the pro forma data does not
purport to represent ZDNet's future financial position or results of
operations.

- -------
(1)  Pro forma net loss per notional share equals ZDNet's net loss for the year
     ended December 31, 1998 divided by the weighted average notional shares
     outstanding.
(2) Notional shares are outstanding shares plus shares attributable to ZD's
    retained interest in ZDNet. This number assumes the offering had been
    completed on January 1, 1998 and gives no effect to outstanding employee
    stock options.
(3) This information should be read in conjunction with the more detailed
    information concerning cash flows from operating, investing and financing
    activities in the Combined Statements of Cash Flows set forth in ZDNet's
    Combined Financial Statements.
(4) "EBITDA" is defined as income before provision for income taxes, interest
    income, 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 ZDNet's operating performance or to cash
    flows as a measure of liquidity. Although Ziff-Davis Inc. believes that
    EBITDA is a standard measure commonly reported and widely used by analysts,
    investors and other interested parties in the media industry, the EBITDA
    presented for ZDNet may not be comparable to similarly titled measures
    reported by other companies.

       Summary Historical and Pro Forma Combined Financial and Other Data

  The following table presents summary combined historical data for ZD as of
and for the years ended December 31, 1996, 1997 and 1998. In addition, the
table presents unaudited summary pro forma data as of and for the year ended
December 31, 1998. The historical financial data was derived from the Combined
Financial Statements of ZD included in this prospectus. An affiliate of Ziff-
Davis Inc. acquired a print publishing business, ZD Publishing, on February 29,
1996; the data does not include results from the acquired businesses for
periods before the date of acquisition. On May 4, 1998, Ziff-Davis Inc.
completed a reorganization described in Note 2 to the Combined Financial
Statements of ZD. Results for periods before the reorganization are not
directly comparable to results for periods after the reorganization. No
historical earnings per share or share data is presented as Ziff-Davis Inc.
does not consider such data meaningful. After the issuance of ZDNet stock,
Ziff-Davis Inc. will report earnings per share data for ZD and ZDNet but not
for Ziff-Davis Inc.

  The pro forma data presented in the table below gives effect to the pro forma
adjustments described in Note 2 to the Combined Financial Statements of ZD and
assumes that:

  . the following transactions had occurred as of January 1, 1998 in the case
    of statement of operations data and other data and as of December 31,
    1998 in the case of balance sheet data:

   (a) the re-classification of each outstanding share of common stock into
       a share of ZD stock,

   (b) the sale of 10,000,000 shares of ZDNet stock in the offering at a
       public offering price of $19.00 per share, less underwriting
       discounts and estimated expenses of the offering assumed to be $1.75
       per share,

   (c) the attribution to ZDNet of the net proceeds from 1,500,000 shares
       and the attribution to ZD of the remaining net proceeds from the
       offering,

   (d) the transfer by ZDNet to ZD, as an inter-group revolving credit
       advance, bearing interest at an assumed rate of 8.5%, of the net
       proceeds attributed to ZDNet,

   (e) the application of the aggregate net proceeds from the offering to
       reduce indebtedness under Ziff-Davis Inc.'s revolving credit
       facility, bearing interest at an assumed rate of 8.5%, and

   (f) the recording of non-cash compensation expense relating to ZDNet
       options.

  . the policies described under "Certain Cash Management and Accounting
    Policies" included in this prospectus had been adhered to for the year
    ended December 31, 1998, and each cash transfer from ZD to ZDNet or from
    ZDNet to ZD had been accounted for as a decrease or increase in the
    inter-group revolving credit advance referred to in (c) above as
    contemplated by those policies.

  The pro forma data is not necessarily indicative of the actual financial
position or results of operations of ZD as of or for the year ended December
31, 1998 or the financial position or results of operations that ZD would have
experienced if the transactions for which the data gives pro forma effect had
in fact occurred at the times assumed. Also, the pro forma data does not

(1) This information should be read in conjunction with the more detailed
    information concerning cash flows from operating, investing and financing
    activities in the Combined Statements of Cash Flows set forth in ZD's
    Combined Financial Statements.

(2) "EBITDA" is defined as income before provision for income taxes, interest

    (a) ZD's EBITDA before losses related to its retained interest in ZDNet and

    EBITDA for the year ended December 31, 1998 does not include a one-time
    restructuring charge of $52,239,000. 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 ZD's operating performance or to cash
    flows as a measure of liquidity. Although Ziff-Davis Inc. 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, the EBITDA presented for ZD may not be comparable to similarly
    titled measures reported by other companies.

     Summary Historical and Pro Forma Consolidated Financial and Other Data

  The following table presents summary historical consolidated data for Ziff-
Davis Inc. as of and for the years ended December 31, 1996, 1997 and 1998. In
addition, the table presents unaudited summary pro forma data as of and for the
year ended December 31, 1998. The historical financial data was derived from
the Consolidated Financial Statements of Ziff-Davis Inc. included in this
prospectus. An affiliate of Ziff-Davis Inc. acquired a print publishing
business, ZDI, on February 29, 1996; the data does not include results from the
acquired business for periods before the date of acquisition. On May 4, 1998,
Ziff-Davis Inc. completed a reorganization described in Note 2 to the
Consolidated Financial Statements of Ziff-Davis Inc. Results for periods before
the reorganization are not directly comparable to results for periods after the
reorganization. No historical or pro forma earnings per share or share data is
presented as Ziff-Davis Inc. does not consider such data meaningful.

  The pro forma data presented gives effect to the pro forma adjustments
described in Note 2 to the Consolidated Financial Statements of Ziff-Davis Inc.
and assumes that the following transactions had occurred as of January 1, 1998
in the case of statement of operations data and other data and as of December
31, 1998 in the case of balance sheet data:

 (a) the sale of 10,000,000 shares of ZDNet stock in the offering at a public
     offering price of $19.00 per share, less underwriting discounts and
     estimated expenses of the offering assumed to be $1.75 per share,

 (b) the application of the aggregate net proceeds from the offering to reduce
     indebtedness under Ziff-Davis Inc.'s revolving credit facility bearing
     interest at an assumed rate of 8.5% and

 (c) the recording of non-cash compensation expense relating to ZDNet options.

  The pro forma data is not necessarily indicative of the actual financial
position or results of operations of Ziff-Davis Inc. as of or for the year
ended December 31, 1998 or the financial position or results of operations that
Ziff-Davis Inc. would have experienced if the transactions for which the data
gives pro forma effect had in fact occurred at the times assumed. Also, the pro
forma data does not purport to represent Ziff-Davis Inc.'s future financial
position or results of operations.

                                  RISK FACTORS


 You should carefully consider the risk factors described below, as well as
 the other information included in this prospectus, before buying shares of
 ZDNet stock.


                      Risk Factors Relating to ZDNet Stock

Holders Of ZDNet Stock Will Be Common Stockholders Of Ziff-Davis Inc. And Will
Be Subject To Risks Associated With An Investment In Ziff-Davis Inc. As A Whole

  We cannot assure you that the market value of ZDNet stock will in fact
reflect the performance of ZDNet as we intend.

  Even though we have allocated all of our consolidated assets, liabilities,
revenue, expenses and cash flow between ZDNet and ZD in order to prepare their
respective financial statements, that allocation will not change the legal
title to any assets or responsibility for any liabilities and will not affect
the rights of any of our creditors. Further, holders of ZDNet stock will not
have any legal rights related to specific assets of ZDNet and, in any
liquidation, will receive a share of the net assets of Ziff-Davis Inc. based on
the relative trading prices of ZDNet stock and ZD stock rather than on any
assessment of the actual value of ZDNet or ZD. Holders of ZDNet stock will
continue to be common stockholders of Ziff-Davis Inc. and, as such, will be
subject to all risks associated with an investment in Ziff-Davis Inc. and all
of our businesses, assets and liabilities. For example, if the cash flow of ZD
is insufficient to satisfy inter-group loans or other debt owed by ZD, ZDNet
would be adversely affected. For more information on the negative effects our
debt obligations could have on holders of Ziff-Davis Inc. common stock,
including holders of ZDNet stock, see "--Other Ziff-Davis Inc. Risks--Ziff-
Davis Inc. Has Significant Debt Obligations And May Be Unable To Obtain
Additional Financing Or Be Required To Divert Funds To Pay Down Principal And
Interest On Its Debt".

If Ziff-Davis Inc. Runs Into Financial Difficulty, The Value Of ZDNet Stock May
Suffer For Reasons Having Nothing To Do With The Prospects For ZDNet

  Financial results of ZD will affect Ziff-Davis Inc.'s consolidated results of
operations, financial position and borrowing costs. This could affect the
results of operations, financial position or borrowing costs of ZDNet or the
market price of ZDNet stock. In addition, net losses of ZD, and any dividends
or distributions on, or repurchases of, ZD stock, will reduce the assets of
Ziff-Davis Inc. legally available for dividends on ZDNet stock. Accordingly,
you should read financial information for ZDNet together with financial
information for ZD and financial information for Ziff-Davis Inc.

Having Two Series Of Common Stock Could Create Potential Conflicts Of Interest
And The Board Of Directors Could Make Decisions That Adversely Affect Holders
Of ZDNet Stock

  Having two series of common stock could give rise to occasions when the
interests of holders of one series might diverge or appear to diverge from the
interests of holders of the other series. Examples include:

  . our decisions as to whether to allocate the proceeds of issuances, or the
    costs of repurchases, of ZDNet stock to ZD in respect of its retained
    interest in ZDNet or to the equity of ZDNet,

                                       17
<PAGE>

  . our decisions as to how to allocate consideration received in connection
    with a merger involving Ziff-Davis Inc. between holders of ZD stock and
    ZDNet stock,

  . our decisions as to whether and when to exchange one series of common
    stock for the other series of common stock,

  . our decisions as to whether and when to approve dispositions of assets of
    either ZD or ZDNet,

  . our decisions as to whether to pay dividends on ZD stock and ZDNet stock
    and

  . our decisions as to whether and how to make transfers of funds between ZD
    and ZDNet and, more generally, our decisions as to other operational and
    financial matters that could be considered detrimental to ZDNet.

  If directors own disproportionate interests, in percentage or value terms, in
ZD stock and ZDNet stock, that disparity could create or appear to create
potential conflicts of interest when they are faced with decisions that could
have different implications for the different series.

Principles Of Delaware Law May Protect Decisions Of The Board Of Directors That
Have A Disparate Impact Upon Holders Of ZD Stock And ZDNet Stock

  Principles of Delaware law established in cases involving differing treatment
of two classes of common stock provide that a board of directors owes an equal
duty to all common stockholders regardless of class or series and does not have
separate or additional duties to either group of stockholders. We are not aware
of any legislative or judicial precedent involving the fiduciary duties of
directors of a Delaware corporation with two classes of common stock with
separate rights related to specified operations of the corporation. However,
under the principles of Delaware law referred to above and the related
principle known as the "business judgment rule", you may not be able to
challenge decisions that have a disparate impact upon holders of ZD stock and
ZDNet stock if the board of directors:

  .  is disinterested and adequately informed with respect to such decisions
     and

  .  acts in good faith and in the belief that it is acting in the best
     interests of Ziff-Davis, Inc.'s stockholders.

The Board Of Directors Has Sole Discretion To Allocate Proceeds Upon Issuances
Or Costs Of Repurchases Of ZDNet Stock To ZDNet Or ZD

  Proceeds from the issuance of ZDNet stock may not necessarily be allocated to
the equity of ZDNet. The board of directors will determine in its sole
discretion whether to allocate the proceeds of issuances or the costs of
repurchases of ZDNet stock to ZD in respect of its retained interest in ZDNet
or to the equity of ZDNet. For a more complete description of how the board of
directors will allocate cash between ZD and ZDNet, see "Certain Cash Management
and Allocation Policies".

                                       18
<PAGE>

Stockholders Will Not Vote On How To Allocate Consideration Received In
Connection With A Merger Among Holders Of ZD Stock And Holders Of ZDNet Stock

  Our charter does not contain any provisions governing how consideration
received in connection with a merger or consolidation involving Ziff-Davis Inc.
is to be allocated between holders of ZD stock and holders of ZDNet stock.
Neither holders of ZD stock nor holders of ZDNet stock will have a separate
class vote in any merger or consolidation so long as we divide the type and
amount of consideration between holders of ZD stock and holders of ZDNet stock
in a manner we determine, in our sole discretion, to be fair. In any such
merger or consolidation, the different ways we may divide the consideration
might have materially different results. As a result, the consideration to be
received by holders of ZDNet stock in any such merger or consolidation may be
materially less valuable than the consideration they would have received if
they had a separate class vote on such merger or consolidation.

We Have The Option To Exchange One Series Of Common Stock For The Other Series
And This May Be Disadvantageous To Holders Of ZDNet Stock

  As described in the summary under the caption "What is Tracking Stock?", we
will have the right to issue shares of one series of common stock in exchange
for outstanding shares of the other series of common stock. Because certain
exchanges would be at a premium, and since we could determine to effect an
exchange at a time when either or both of ZD stock and ZDNet stock may be
considered to be overvalued or undervalued, any such exchange may be
disadvantageous to holders of ZDNet stock. In addition, any such exchange would
preclude holders of the exchanged series of common stock from retaining their
investment in a security that is intended to reflect separately the performance
of the related group.

We May Dispose Of Assets Of Either ZD Or ZDNet Without Your Approval

  Delaware law requires stockholder approval only for a sale or other
disposition of all or substantially all of the assets of Ziff-Davis Inc. As
long as the assets attributed to ZD or ZDNet represent less than substantially
all of Ziff-Davis Inc.'s assets, we may approve sales and other dispositions of
any amount of the assets of either ZD or ZDNet without any stockholder
approval. If we dispose of all or substantially all of the assets of either ZD
or ZDNet, we would be required, if the disposition is not an exempt disposition
under the terms of our charter, to choose one of the following three
alternatives:

  . declare and pay a dividend,

  . redeem shares of the relevant series of stock or

  . exchange shares of one series for outstanding shares of the other series
    at a 10% premium.

  Consequently, holders of either series of common stock may receive less value
for their shares than the value that a third-party buyer might pay for all or
substantially all of the assets of such group. In addition, if we elect to
complete an exchange in connection with the disposition, we could do so as one
of the three alternatives required in connection with

                                       19
<PAGE>

the disposition or as an optional exchange that may in some cases be at no
premium, and any such exchange could be completed at a time when ZDNet stock or
ZD stock may be considered to be overvalued or undervalued.

  The board of directors will decide, in its sole discretion, how to proceed
and is not required to select the option that would result in the highest value
to holders of ZDNet stock. This decision, however, will be subject to the board
of directors' general fiduciary duties as described above.

We Do Not Expect To Pay Dividends For The Foreseeable Future

  Our various debt instruments currently prohibit the payment of dividends, and
in any event, we do not expect to pay any dividends for the foreseeable future.

We May Not Pay Dividends Equally On ZD Stock And ZDNet Stock

  We have the right to pay dividends on ZD stock or ZDNet stock, or both, in
equal or unequal amounts, notwithstanding:

  . the performance of either ZD or ZDNet,

  . the amount of assets available for dividends on either series,

  . the amount of prior dividends declared on either series or

  . any other factor.

In addition, net losses of ZD, and any dividends or distributions on, or
repurchases of, ZD stock, will reduce the assets of Ziff-Davis Inc. legally
available for dividends on ZDNet stock.

The Board Of Directors May Make Operational And Financial Decisions Affecting
ZD And ZDNet Differently

  The board of directors, in its sole discretion, will make operational and
financial decisions and implement policies that affect the businesses of ZD and
ZDNet differently. Examples include:

  . transfers of funds between ZD and ZDNet,

  . the manner of accounting for transfers of funds between ZD and ZDNet,

  . allocation of funds for capital expenditures,

  . other transactions between ZD and ZDNet,

  . the allocation of financing opportunities in public markets and

  . the allocation of business opportunities, resources and personnel.

Decisions of the board of directors may favor either ZD or ZDNet at the expense
of the other. For example, the decision to provide funds for ZD may adversely
affect the ability of ZDNet to obtain funds sufficient to implement its growth
strategies.

                                       20
<PAGE>

The Board Of Directors Has Sole Discretion To Change Certain Cash Management
And Allocation Policies And May Change These Policies In A Manner That Is
Disadvantageous To Holders Of ZDNet Stock Or ZD Stock

  The board of directors has adopted certain policies relating to cash
management and allocations between ZD and ZDNet. Although it has no present
intention to do so, the board of directors may, in its sole discretion, modify,
rescind or add to any of these policies in a manner that is disadvantageous to
holders of ZD stock or ZDNet stock. The board of directors' discretion to
change these policies makes an investment in ZDNet stock riskier than an
investment in ordinary common stock. For a more comprehensive description of
these policies, see "Certain Cash Management and Allocation Policies".

Under Its Current Policies The Board Of Directors Has Sole Discretion
Concerning Various Cash Management Matters

  The discretion of the board of directors in the area of cash management makes
an investment in ZDNet stock riskier than an investment in ordinary common
stock.

  The board of directors will determine, in its sole discretion, whether to
transfer any cash to or from ZDNet. Moreover, the board of directors has sole
discretion to determine

  . whether a transfer of cash from ZDNet to ZD will be treated as a
    revolving credit advance, a long-term loan or a return of capital and

  . whether a transfer of cash from ZD to ZDNet will be treated as a
    revolving credit advance, a long-term loan or a contribution to capital.

  The determination of the board of directors as to how to account for a cash
transfer will affect the amount of interest expense and interest income,
stockholders' equity and number of notional shares of ZDNet stock outstanding
as reflected in the financial statements of ZD and ZDNet.

  If ZD is unable to repay advances or loans owed to ZDNet, ZDNet would be
adversely affected. Also, if ZDNet extends an advance or loan to ZD at an
interest rate below ZDNet's cost of funds or opportunity cost, ZDNet's results
would be adversely affected to the extent of the difference.

  Any cash transfers we determine to account for as capital contributions or
returns of capital will increase or decrease ZD's retained interest in ZDNet.
Although we would calculate any change in the retained interest by reference to
the then current market value of ZDNet stock, the change could come at a time
when ZDNet stock is considered to be overvalued or undervalued. Also, any
increase in ZD's retained interest in ZDNet will reduce the percentage of ZDNet
intended to be represented by outstanding ZDNet stock.

The Board Of Directors Has Broad Discretion About A Variety Of Allocation
Matters And May Make Such Allocations In A Manner That Is Disadvantageous To
Holders Of ZDNet Stock Or ZD Stock

  The board of directors will determine, in its sole discretion, how to
allocate issuances of Ziff-Davis Inc. debt or preferred stock between ZD and
ZDNet. Moreover, the board of

                                       21
<PAGE>

directors will have broad discretion as to how to allocate Ziff-Davis Inc.'s
consolidated assets, liabilities, revenue, expenses and cash flow between ZD
and ZDNet. The discretion of the board of directors in these areas makes an
investment in ZDNet stock riskier than an investment in ordinary common stock.

Holders Of ZDNet Stock Will Vote Together With Holders Of ZD Stock And Will
Have Limited Separate Voting Rights

  Holders of ZD stock and ZDNet stock will vote together as a single class,
except in certain limited circumstances provided under the Delaware general
corporation law. When holders of ZD stock and ZDNet stock vote together as a
single class, holders of the series of common stock having a majority of the
votes will be in a position to control the outcome of the vote even if the
matter involves a conflict of interest between holders of ZD stock and holders
of ZDNet stock.

The Voting Power Of ZDNet Stock Will Fluctuate Based On Its Market Value

  Each share of ZD stock will have one vote and each share of ZDNet stock will
have a variable number of votes based on the market value of a share of ZDNet
stock as compared to the market value of a share of ZD stock over a specified
20-trading day period prior to the date of the vote. Accordingly, the relative
voting power of ZD stock and ZDNet stock will fluctuate from time to time based
on the respective market values of ZD stock and ZDNet stock and the number of
shares outstanding of each of ZD stock and ZDNet stock.

We Cannot Assure You That A Market Will Develop For ZDNet Stock Or What Its
Market Price Will Be

  There is currently no public trading market for ZDNet stock and we cannot
assure you that one will develop or be sustained after the offering. We cannot
predict the prices at which ZDNet stock will trade after the offering. The
initial public offering price for ZDNet stock was determined through our
negotiations with the underwriters and may not bear any relationship to the
market price at which ZDNet stock will trade after the offering or to any other
established criteria for value.

  Certain terms of ZD stock and ZDNet stock may adversely affect the trading
price of ZDNet stock. These terms include:

  . the right of the board of directors to exchange shares of one series of
    common stock for shares of the other series,

  . the discretion of the board of directors in making determinations
    relating to a variety of cash management and allocation matters and

  . the variable voting power of ZDNet stock as compared to ZD stock.

Such terms may limit the market price of ZDNet stock.

                                       22

The Market Price Of ZDNet Stock Will Fluctuate And Could Fluctuate
Significantly, Subjecting Ziff-Davis Inc. To Securities Class Action Litigation

  The stock market has experienced extreme price and volume fluctuations. The
market prices of securities of Internet-related companies, in particular, have
been especially volatile. In the past, companies that have experienced such
volatility have sometimes been the object of securities class action
litigation. Securities class action litigation may result in substantial costs
and a diversion of management's attention and resources. For a description of
certain class action and derivative litigation to which Ziff-Davis Inc. is a
party, see "ZDNet Description of Business--Legal Proceedings".

The Market Price Of ZDNet Stock May Not Reflect The Performance Of ZDNet As We
Intend And Holders Of ZDNet Stock Will Be Subject To All Risks Associated With
An Investment In Ziff-Davis Inc. As A Whole

  We cannot assure you that the market price of ZDNet stock will in fact
reflect the performance of ZDNet as we intend. Holders of ZDNet stock will
continue to be common stockholders of Ziff-Davis Inc. and, as such, will be
subject to all risks associated with an investment in Ziff-Davis Inc. and all
of its businesses, assets and liabilities.

There Are Many Factors Which May Inhibit Or Prevent Acquisition Bids For ZDNet
Or ZD

  SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates currently own
approximately 70% of Ziff-Davis Inc.'s outstanding common stock. As long as
SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates continue to own a
majority of the voting power of our common stock, no person interested in
acquiring Ziff-Davis Inc. or ZDNet will be able to do so without obtaining the
consent of SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates.

  If ZD and ZDNet were separate companies, any person interested in acquiring
either ZD or ZDNet without negotiating with management could seek control of
that entity by obtaining control of its outstanding voting stock by means of a
tender offer or proxy contest. Although we intend ZD stock and ZDNet stock to
reflect the separate performance of ZD and ZDNet, a person interested in
acquiring only ZD or ZDNet without negotiation with Ziff-Davis Inc.'s
management could obtain control of ZD or ZDNet only by obtaining control of the
outstanding voting stock of Ziff-Davis Inc.

  The existence of two series of common stock could present complexities and
could in certain circumstances pose obstacles, financial and otherwise, to an
acquiring person. The existence of two series of common stock could, under
certain circumstances, prevent stockholders from profiting from an increase in
the market value of their shares as a result of a change in control of Ziff-
Davis Inc. by delaying or preventing such a change in control.

  After giving effect to the offering and assuming the underwriters do not
exercise their option to purchase additional shares, there will be
approximately 95 million shares of common stock available for future issuance
without further stockholder approval. One of the effects of the existence of
authorized and unissued common stock and preferred stock could be to enable the
board of directors to issue shares to persons friendly to current

                                       23
<PAGE>

management, which could render more difficult or discourage an attempt to
obtain control of Ziff-Davis Inc. by means of a merger, tender offer, proxy
contest or otherwise, and thereby protect the continuity of our management.
Such additional shares also could be used to dilute the stock ownership of
persons seeking to obtain control of Ziff-Davis Inc.

  In addition, certain provisions of our charter and by-laws, and certain
provisions of Delaware law, may inhibit changes of control not approved by the
board of directors. For additional takeover constraints, see "Description of
Capital Stock--Certain Other Provisions of the Amended Charter and By-laws" and
"--Certain Provisions of Delaware Law".

The Value Of ZDNet Stock May Decline Due To Future Issuances Of ZDNet Stock

  Our charter allows the board of directors, in its sole discretion, to issue
authorized but unissued shares of common stock. This could dilute the value of
shares of ZDNet stock. The board of directors may issue ZD stock or ZDNet stock
to, among other things:

  . raise capital,

  . provide compensation or benefits to employees,

  . pay stock dividends or

  . acquire companies or businesses.

  Under the Delaware general corporation law, the board of directors would not
need your approval for these issuances. We do not intend to seek your approval
for any such issuances unless:

  . stock exchange regulations or other applicable law require approval or

  . the board of directors deems it advisable.

The Market Price Of ZDNet Stock May Decline Due To Shares Of ZDNet Stock
Eligible For Future Sale

  Upon completion of the offering, we expect to have 10.0 million shares of
ZDNet stock outstanding, or 11.5 million shares if the underwriters fully
exercise their option to purchase additional shares. These shares will be
freely tradeable without restriction by persons other than affiliates of Ziff-
Davis Inc. We expect up to 100,000 shares will be owned by certain affiliates
and will therefore be deemed restricted securities within the meaning of the
Securities Act. In addition, ZD and ZDNet employees will have the right to
purchase approximately 10.0 million additional shares of ZDNet stock under
employee stock options, subject to vesting requirements. Also, upon completion
of the offering and assuming the underwriters do not exercise their option to
purchase additional shares, we will be entitled to issue up to approximately
70.0 million additional shares of ZDNet stock, of which, up to 61.5 million
shares could be for the account of ZD in respect of its retained interest in
ZDNet.

  We cannot predict the effect, if any, that sales of ZDNet stock, or the
availability of shares for sale, will have on the market price prevailing from
time to time. Nevertheless, sales of significant amounts of ZDNet stock in the
public market, or the perception that such sales may occur, could adversely
affect prevailing market prices. For a more detailed description of the effect
of future sales of ZDNet stock, see "Shares Eligible for Future Sale".

                         Risk Factors Relating To ZDNet

ZDNet Has An Extremely Limited Operating History And A History Of Net Losses
And There Is No Assurance ZDNet Will Report Net Income In The Future

  ZDNet has an extremely limited operating history and an investor must
consider the risks, expenses and difficulties frequently encountered by such
companies, particularly in the new and rapidly evolving market for Internet
products, content and services. We cannot assure you that ZDNet will be
successful in addressing such risks. Although ZDNet has experienced revenue
growth in recent periods, we cannot assure you that ZDNet's revenue will
continue to grow or continue at its current level.

  ZDNet has incurred significant net losses in the past, $21.2 million in 1997
and $7.9 million in 1998. For more information regarding these net losses, see
"ZDNet Selected Historical Combined Financial and Other Data" and ZDNet's
Combined Financial Statements in this prospectus. We cannot assure you that
ZDNet will report net income in the future.

We Cannot Accurately Predict ZDNet's Future Revenue

  As a result of the evolving nature of the Internet and ZDNet's limited
operating history, we cannot accurately forecast its revenue. Current and
future expense levels are based principally on estimated future revenue and are
to a large extent fixed. Accordingly, ZDNet may be unable to adjust spending to
compensate for any unexpected revenue shortfall. If ZDNet's actual revenue is
less than its estimated revenue, this could have an immediate material adverse
effect on ZDNet's profits and liquidity.

ZDNets' Quarterly Operating Results May Fluctuate Significantly And Are Not
Reliable Indicators Of Its Future Performance

  ZDNet's quarterly operating results may fluctuate significantly because of a
variety of factors, many of which are outside our control, including:

  . overall usage levels of the Internet and of ZDNet's sites in particular,

  . demand for Internet advertising and the loss of advertisers,

  . seasonal trends in Internet use and advertising,

  . the amount and timing of ZDNet's capital expenditures,

  . costs relating to the expansion of ZDNet's operations and the
    introduction of new sites and services,

  . price competition or pricing changes in Internet advertising and

  . costs relating to technical difficulties or system downtime.

  We believe Internet advertising typically slows in the first quarter of the
year. Historically, ZDNet has experienced lower advertising and lower revenue
in the first quarter of each year as compared to the fourth quarter of the
prior year. Seasonality and cyclicality in the level of Internet advertising
expenditures generally could become more pronounced in the future as the
Internet becomes more accepted as an advertising vehicle. If a large

                                       25
<PAGE>

number of advertisers do not advertise in a given quarter or if advertising
revenue is deferred, ZDNet's revenue in that quarter could be substantially
reduced. This would have a material adverse affect on ZDNet's operating
results. Quarterly comparisons of ZDNet's results of operations are not
reliable and you should not rely on them as an indication of its future
performance. For additional information about the seasonality of ZDNet's
revenue, see "ZDNet Management's Discussion and Analysis of Financial Condition
and Results of Operations".

ZDNet's Future Revenue Is Dependent On The Growth Of Internet Use And The
Acceptance Of The Internet As An Advertising And Commerce Medium

  ZDNet's future revenue will depend largely on the widespread acceptance and
use of the Internet as an information source and as an advertising and commerce
vehicle. Rapid growth in Internet use is a recent trend and market acceptance
of the Internet as an advertising and commercial medium is highly uncertain.

  The Internet may not be accepted as a viable advertising and commerce medium
for distribution of information and engaging in commerce for a number of
reasons, including:

  .inadequate development of the network infrastructure,

  .inadequate development of enabling technologies,

  .insufficient commercial support for Internet advertising,

  .concerns about privacy and security among users and

  .lack of widely accepted standards for measuring the effectiveness of
   advertising on the Internet.

ZDNet Depends On Advertising As A Principal Source Of Its Revenue

  ZDNet derived 86% of its revenue in 1998 from the sale of advertising on its
Internet sites and we expect that advertising revenue will continue to be the
principal source of its revenue in the foreseeable future. Most of ZDNet's
advertising contracts are either short-term contracts and/or can be terminated
by the advertiser at any time with little notice. We cannot assure you that
ZDNet will be able to retain current advertisers or obtain new advertising
contracts.

  ZDNet's ability to generate advertising revenue will depend on several
factors, including:

  .the continued development of the Internet as an advertising medium,

  .the pricing of advertising on other Internet sites,

  .the amount of traffic on ZDNet's network of sites,

  .pricing pressures, delays and new product launches,

  .ZDNet's ability to achieve, demonstrate and maintain attractive user
   demographics and

  .ZDNet's ability to develop and retain a skilled advertising sales force.

                                       26
<PAGE>

ZDNet Is Increasingly Dependent On, And Receives A Significant Percentage Of
Its Revenue From, A Limited Number of Advertisers

  A relatively small number of advertisers contribute a significant percentage
of ZDNet's consolidated revenue. In 1998, ZDNet's top 20 advertising customers
accounted for approximately 46.5% of its net advertising revenue. These
advertising clients, and its other advertising clients, may not continue to use
ZDNet's services to the same extent, or at all, in the future. A significant
reduction in advertising by one or more of ZDNet's largest advertisers would
have a material adverse effect on ZDNet's profits and liquidity.

ZDNet Depends On Arrangements With Third Parties For Internet Traffic To Its
Sites And ZDNet's Failure to Maintain These Arrangements With Third Parties
Could Adversely Affect Its Business

  ZDNet's ability to advertise on and maintain links from other Internet sites
is an important element to its success. Traffic originating from links existing
on other Internet sites, particularly search engines, directories and other
navigational tools managed by Internet service providers and Web browser
companies, is an important segment of the overall traffic on ZDNet's Internet
sites. ZDNet has special linking arrangements to generate additional traffic
with Yahoo!, Excite and MSNBC which are either short-term contracts and/or can
be terminated with little notice. There is intense competition for these types
of linking arrangements. We cannot assure you that these arrangements will be
maintained or that advertising or links will continue to be available on
reasonable commercial terms or at all.

ZDNet Depends On Licensed Technology From Third Parties And ZDNet's Failure To
Maintain These Arrangements With Third Parties Could Adversely Affect Its
Business

  ZDNet relies on certain technology licensed from third parties such as
Vignette's Storyserver, Thunderstone's Texis Search Engine and Netscape's Web
Server Software for use in operating and managing its Internet sites and
providing related services to users and advertisers. ZDNet's ability to
generate revenue from Internet commerce may also depend on data encryption and
authentication technologies that it may be required to license from third
parties. We cannot assure you that such technology licenses will be available
at all, that they will be available on reasonable commercial terms or that they
will operate as intended.

ZDNet's Competitive Position Depends On Its Ability To Attract And Retain Key
Personnel

  ZDNet's failure to attract and retain qualified personnel could diminish its
competitive position. ZDNet's performance is substantially dependent on the
continued services and performance of its senior executive officers and other
key personnel. ZDNet does not have long-term employment agreements with any of
its key personnel and maintains no "key person" life insurance policies.
ZDNet's future success also depends on its ability to identify, attract, retain
and motivate highly skilled editorial, technical, managerial, sales, marketing
and customer service personnel. Competition for such persons is intense. We
cannot assure you that ZDNet will be able to attract or retain such personnel.

                                       27
<PAGE>

ZDNet May Not Be Able To Adequately Respond To Technological Change

  The market for Internet products and services is characterized by rapid
technological developments, frequent new product introductions and evolving
industry standards. ZDNet will be required to continually improve the
performance, features and reliability of its network infrastructure and
Internet sites, particularly in response to competition and changing customer
demands. We cannot assure you that ZDNet will be successful in responding
rapidly, cost-effectively or adequately to such developments.

ZDNet's Competition Is Intense And Is Expected To Increase Significantly

  We cannot assure you that ZDNet will be able to maintain its competitive
position. Competition among Internet content providers is intense and is
expected to increase significantly in the future. The market for Internet
content sites is rapidly evolving and barriers to entry are low, enabling
newcomers to launch competitive sites at relatively low cost. Moreover,
increased competition could result in price reductions, reduced margins or loss
of market share, any of which could have an effect on our future revenue and
profits.

  We believe ZDNet competes most directly with Web sites specializing in broad-
based technology information. These include c|net, CMP, Internet.com and IDG.
ZDNet also generally competes for users and advertisers with:

  . Internet portals and search sites that help users access information
    rather than create original content and are not specifically focused on
    technology related information, such as Excite, Infoseek, Lycos and
    Yahoo!,

  . general news sites, such as CNN and ABC,

  . general purpose online service providers, such as America Online and MSN,

  . browser/software companies offering information services, such as
    Microsoft and Netscape, and

  . large general-interest sites, such as Time Warner's pathfinder.com.

  In addition, ZDNet competes with traditional media content businesses such as
newspapers, magazines, radio and television. In order to compete successfully
and attract users, advertisers and strategic partners, ZDNet must continue to
provide high quality, engaging content in a timely and cost-effective manner.

To Remain Competitive, ZDNet Must Constantly Expand And Develop New Content
Areas And Services. This Is Inherently Risky And Expensive

  ZDNet's future success may depend in part on its ability to continue
expanding its Internet sites to include new subject matters and services. Costs
related to developing new content areas and services are expensed as they are
incurred while revenue related to these new content areas and services
typically builds over time. Accordingly, ZDNet's profitability from year to
year may be adversely affected by the number and timing of new launches. In
addition, we cannot assure you that any new areas or services will be developed
in a timely or cost-effective manner or that they will be successful.

                                       28
<PAGE>

We Cannot Assure You That ZDNet Will Continue To Develop The ZDNet Brand

  We cannot assure you that ZDNet will be able to continue to develop its
brand. ZDNet believes brand identity is important to attracting and expanding
its user base, Internet traffic and advertising and commerce relationships.
ZDNet believes the significance of brand recognition will intensify as the
number of Internet sites increases.

Any Capacity Constraints Or System Disruptions Could Have A Material Adverse
Effect On ZDNet

  The performance and reliability of ZDNet's Internet sites and network
infrastructure are critical to its reputation and ability to attract and retain
users, advertisers, merchants and strategic partners. Any system error or
failure, or a sudden and significant increase in traffic, may result in the
unavailability of sites and significantly delay response times. Individual,
sustained or repeated occurrences could result in a loss of potential or
existing users, advertisers or strategic partners. In addition, because ZDNet's
advertising revenue is directly related to the number of advertisements it
delivers to users, system interruptions or delays would reduce the number of
impressions delivered and thereby reduce its revenue.

  ZDNet's systems and operations are vulnerable to interruption or malfunction
due to certain events beyond its control, including natural disasters,
telecommunications failures and computer hacking. ZDNet also relies on Web
browsers and online service providers to provide Internet access to its sites.
We cannot assure you that ZDNet will be able to expand its network
infrastructure, either itself or through use of third-party hosting systems or
service providers, on a timely basis sufficient to meet demand. ZDNet presently
has only a limited amount of redundant facilities or systems, no formal
disaster recovery plan and no sufficient business interruption insurance to
compensate for losses that may occur. Any interruption to its systems or
operations could have a material adverse effect on ZDNet's business and its
ability to retain users, advertisers and strategic partners.

ZDNet's Networks May Be Vulnerable To Security Risks

  ZDNet's networks may be vulnerable to unauthorized access, computer hacking,
computer viruses and other security problems. A user who circumvents security
measures could misappropriate proprietary information or cause interruptions or
malfunctions in ZDNet's operations. ZDNet may be required to expend significant
resources to protect against the threat of such security breaches or to
alleviate problems caused by such breaches. Although ZDNet intends to continue
to implement industry-standard security measures, such measures may be
inadequate.

Increased Government Regulation Of The Internet Could Have A Material Adverse
Effect On ZDNet

   Increased government regulation, or the application of existing laws to
online activities, could inhibit Internet growth, expose ZDNet and other online
content providers to additional liabilities and increase the cost of doing
business. This could have a material adverse effect on ZDNet's profits and
liquidity. The increasing popularity and use of the Internet and other online
services may lead to the adoption of new laws and regulations in the U.S. or
elsewhere covering issues such as online privacy, copyright and trademark,
sales taxes and

                                       29
<PAGE>

fair business practices or which require qualification to do business as a
foreign corporation in certain jurisdictions. For instance, the European
Union's recently adopted privacy regulations may limit the collection and use
of certain user information.

ZDNet Relies On Intellectual Property Rights Which May Not Be Adequately
Protected Under Current Laws

  To establish and protect its trademark, service mark and other proprietary
rights in its products and services, ZDNet relies on a combination of:

  . copyright, unfair competition, trademark, service mark and trade secret
    laws,

  . confidentiality agreements with its licensees and other third parties and

  . confidentiality agreements and policies covering its employees.

  We cannot assure you that these measures will be adequate, that ZDNet will be
able to secure registrations for all of its marks in the U.S. or
internationally or that third parties will not infringe upon or misappropriate
its proprietary rights. Any infringement, misappropriation, or litigation
relating to intellectual property rights, may divert management's attention and
ZDNet's funds to litigate such claims.

  Legal standards relating to the validity, enforceability and scope of
protection of certain proprietary rights in Internet-related business are
uncertain and evolving. In particular, new domain name registration and
ownership priority procedures may be adopted which may make it more difficult
for ZDNet and other Internet businesses to retain or obtain desirable domain
names.

ZDNet May Incur Liability For Its Internet Content And User Data

  As a content provider, ZDNet may face potential liability for intellectual
property infringement, defamation, indecency and other claims. In addition,
ZDNet may incur liability for unauthorized duplication or distribution of
third-party content or materials or for information collected from and about
its users. We cannot assure you that third parties or users will not bring
claims against ZDNet relating to proprietary rights or use of personal
information. Although ZDNet seeks to obtain indemnification from strategic
partners for any liability resulting from licensed content or linked sites, we
cannot assure you that such indemnities will always be obtainable or adequate.
ZDNet's general liability insurance may not cover or be adequate for potential
claims of this type.

ZDNet May Not Be Able To Adequately Manage Its Growth

  ZDNet will need to effectively plan and manage its business to succeed in the
rapidly evolving Internet industry. ZDNet continues to increase the scope of
its operations and has grown its workforce substantially. As of December 31,
1997, ZDNet had a total of 252 employees and, as of December 31, 1998, ZDNet
had a total of 316 employees--a growth of 25.4%. This growth has placed, and
future growth may place, a significant strain on ZDNet's resources. For
example, we expect that the variety of advertising products available on ZDNet
sites will expand, increasing demands on ZDNet's billing and collection systems
and requiring additional resources to properly determine pricing and
discounting structures. ZDNet expects that it will need to continue to improve
its financial and management controls and reporting systems and procedures, and
will need to continue to expand, train and manage its workforce.

ZDNet's Acquisition And Investment Strategy May Not Be Successful And Could
Adversely Affect ZDNet's Business

  ZDNet may acquire or make investments in new or complementary businesses,
products, services or technologies. We cannot assure you that ZDNet will be
able to identify suitable acquisition or investment candidates. Even if ZDNet
does identify suitable candidates, we cannot assure you that ZDNet will be able
to make such acquisitions or investments on reasonable commercial terms or
successfully assimilate personnel, operations, products, services or
technologies into its operations. This could disrupt ZDNet's ongoing business,
distract ZDNet's management and employees, increase ZDNet's expenses, including
amortization of goodwill, and materially and adversely affect ZDNet's profits
and liquidity. Furthermore, the incurrence or issuance of debt or equity
securities may be attributed to ZDNet to fund any future ZDNet acquisitions.

ZDNet's Computer Systems, And Those Of Others On Whom It Relies, May Not
Achieve Year 2000 Readiness

  Programming codes in existing computer systems and software may not reliably
recognize date-sensitive information when the calendar year changes to 2000.
Systems or software that do not properly recognize such information could
generate erroneous data or fail. We are in the process of identifying and
testing our computer systems and software for Year 2000 readiness. In addition,
we are in the process of working with third parties on whom we rely for system
and database management to ensure Year 2000 readiness. We have not verified
that such third parties are Year 2000 compliant. We cannot assure you that our
systems or software, or third-party systems or software on which we rely, will
be Year 2000 compliant. Significant uncertainty exists concerning the potential
costs and effects associated with Year 2000 compliance. If Ziff-Davis Inc. or
any subscribers, advertisers, licensors, vendors or other third parties on whom
it relies experiences a Year 2000 compliance problem, this could have a
material adverse effect on ZDNet's profits and liquidity. For more information
regarding ZDNet's Year 2000 readiness, see "ZDNet Management's Discussion And
Analysis of Financial Condition and Results of Operations--Year 2000 Readiness
Disclosure" in this prospectus.

ZDNet Intends to Expand Its International Operations And May Encounter A Number
Of Problems Doing So. There Are Also A Number of Risks Associated With
International Operations That Could Adversely Affect ZDNet's Business

  Expansion of International Operations. One component of ZDNet's growth
strategy is to further expand into international markets. ZDNet's international
operations are at an early stage of development and have an extremely limited
operating history. In addition, the markets in which ZDNet has undertaken
international expansion have technology and online industries that are less
well developed than in the U.S.

  Risks of International Operations. There are certain risks inherent in doing
business in international markets, such as the following:

  . uncertainty of product acceptance by different cultures,

  . unforeseen changes in regulatory requirements,

  . difficulties in staffing and managing multinational operations,

  . state-imposed restrictions on the repatriation of funds,

                                       31
<PAGE>

  . currency fluctuations,

  . difficulties in finding appropriate foreign licensees or joint venture
    partners and

  . potentially adverse tax consequences.

  There is a risk that such factors will have an adverse effect on ZDNet's
ability to successfully operate internationally and on its profits and
liquidity.

                          Other Ziff-Davis Inc. Risks

Ziff-Davis Inc. Has Only Operated As A Stand-Alone Company For Less Than A Year

  We have only operated as a stand-alone company since May 1998. Until October
1997, our publishing business and our trade show and conference businesses were
managed as separate SOFTBANK Corp. subsidiaries. Our success depends in part on
our continued ability to manage the combined enterprise.

Ziff-Davis Inc.'s Historical Financial Information Is Not Particularly Relevant
To Its Actual Results

  Our financial information included in this prospectus does not reflect what
the actual results of operations, financial position and cash flows would have
been had Ziff-Davis Inc. existed prior to the periods presented. In addition,
the financial information is not necessarily indicative of our future results
of operations, financial position and cash flows. For more information
regarding our operating results, see "Ziff-Davis Inc. Management's Discussion
and Analysis of Financial Condition and Results of Operations--Presentation of
Financial Information".

Ziff-Davis Inc. Is Controlled By Its Principal Stockholders. This Creates
Potential Conflicts Of Interest

  SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates own approximately 70%
of Ziff-Davis Inc.'s outstanding shares. As a result, SOFTBANK Corp. and its
non-Ziff-Davis Inc. affiliates could elect all the members of the board of
directors. SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates could also
control those actions requiring the approval of the holders of a majority of
the voting stock, including amendments to our charter and any business
combinations. This concentration of ownership could prevent a change in control
of Ziff-Davis Inc. that might otherwise be beneficial to stockholders.

  We have entered into certain agreements with SOFTBANK Corp. and its non-Ziff-
Davis Inc. affiliates governing ongoing relationships. These agreements include
certain licensing and management agreements relating to publications, events,
ZDNet and ZDTV, a 24-hour cable television channel and integrated Web site
focused exclusively on computers, technology and the Internet. In addition,
SOFTBANK Corp. has given us an undertaking that, as long as it owns 40% of the
voting power in our stock and can elect a majority of the board of directors,
it will not expand its operations outside Japan involving:

  . publishing information on computing and Internet-related technology
    through print media, CD-ROM/DVD, Internet and television or

                                       32
<PAGE>

  . producing trade shows, conferences, exhibitions and similar events
    primarily related to computing and Internet-related technology

that compete with us without the prior approval of our employee directors after
consulting with our independent directors.

  This undertaking does not preclude investments by venture capital funds
managed by SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates which invest
in, among other things, computer and Internet-related companies. These funds
may be able to co-invest with or compete with us with respect to new
investments. In addition, SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates
may also develop new funds which may compete with us for investment
opportunities. We have agreed not to compete with SOFTBANK Corp. in Japan
without the prior approval of SOFTBANK Corp.'s board of directors and have
given SOFTBANK Corp. and its non-Ziff-Davis Inc. affiliates the continuing
right to license all of our products and services in Japan. These arrangements
and undertakings might be less favorable than arrangements negotiated at arm's
length between unrelated parties.

Ziff-Davis Inc. Has Significant Debt Obligations And May Be Unable To Obtain
Additional Financing Or Be Required To Divert Funds To Pay Down Principal And
Interest On Its Debt

  At December 31, 1998:

  . Ziff-Davis Inc.'s total debt was approximately $1.5 billion.

  . Ziff-Davis Inc.'s total stockholders' equity was approximately $1.4
    billion.

  . Ziff-Davis Inc.'s total debt was 53% of total capitalization.

  Our indebtedness is substantial in relation to stockholders' equity. The
degree to which we are leveraged is important because:

  . It may impair our ability to obtain additional financing for working
    capital, capital expenditures, acquisitions or general corporate
    purposes.

  . It may reduce the funds available to us for our operations if a
    substantial portion of our cash flow from operations is dedicated to the
    payment of principal and interest on our indebtedness.

  . It may impair our ability to incur additional debt because of financial
    and other restrictive covenants, including those relating to the
    incurrence of additional indebtedness, the creation of liens, the payment
    of dividends and sales of assets.

  . It may increase our vulnerability to adverse general economic conditions,
    including increases in interest rates.

  Our indebtedness requires us to use a substantial portion of our cash flow to
pay down principal and interest on our outstanding debt. This reduces the funds
available for capital expenditures and future business opportunities.

  Our credit facility is secured, in part, by a first priority security
interest in the capital stock of certain of our subsidiaries and is guaranteed
by certain of our wholly owned domestic subsidiaries, including ZD Inc. and ZD
Events Inc.

                                       33
<PAGE>

  On December 11, 1998, Standard & Poors lowered its corporate credit and bank
loan ratings for Ziff-Davis Inc. to BB- from BB and Ziff-Davis Inc.'s
subordinated debt rating to B from B+. This downgrade had no impact on the
terms of our current borrowings. While the downgrade may make future
borrowings more expensive, we do not believe this will have a material impact
on our liquidity or our access to credit markets.

  On December 16, 1998, the lenders on our $1.35 billion credit facility
agreed to amend certain provisions of that facility. The amended provisions
include an increase to our allowed leverage ratios. In return, we have agreed
to pay a one-time fee of $3.375 million, and increase our interest rates on
amounts borrowed under the facility to rates currently ranging from LIBOR plus
2.875% to LIBOR plus 3.375%, depending on the type of loan.

Ziff-Davis Inc.'s Revenue Is Dependent On Demand For Advertising

  Ziff-Davis Inc. derived 52% of its total revenue in 1998 from advertising
sales and we expect that advertising revenue will continue to be a principal
source of our revenue in the foreseeable future. Most of Ziff-Davis Inc.'s
advertising contracts are either short-term contracts and/or can be terminated
by the advertiser at any time with little notice. We cannot assure you that we
will be able to retain current advertisers or obtain new advertising
contracts.

  If a general economic downturn or a U.S. recession occurs in the future, our
advertisers may reduce their advertising budgets. In addition, factors such as
pricing pressures, delays and new product launches may affect technology
product advertisers. We cannot assure you that technology product advertisers
will maintain current levels of advertising in special interest magazines and
events instead of advertising in more general interest media. Any material
decline in the demand for advertising by technology product advertisers could
have an adverse effect on our profits and liquidity.

Many Factors Have Contributed To A Reduced Demand For Advertising And
Ziff-Davis Inc. Expects These Factors To Continue

  Margin pressure on computer equipment manufacturers, industry and product
delays, lower demand in Asia and a focus on the Year 2000 transition are
contributing to a reduced demand for advertising in our magazines, principally
PC Magazine, PC/Computing, Computer Shopper and PC Week. We believe these
factors will continue. In part as a result of these factors, earnings before
interest, taxes, depreciation and amortization for the fourth quarter of 1998
were significantly lower than they were for the fourth quarter of 1997.

  As a result of this reduced demand, we announced on October 8, 1998 a
company-wide restructuring in which we discontinued three publications,
Internet Business, Equip and Windows Pro, and reduced our workforce by
approximately 10%. In the fourth quarter of 1998, we took a pre-tax charge of
$52.2 million as part of this restructuring.

Ziff-Davis Inc. Is Increasingly Dependent On, And Receives A Significant
Percentage Of Its Revenue From, A Limited Number Of Advertisers

  A relatively small number of advertisers contribute a significant percentage
of Ziff-Davis Inc.'s advertising revenue. In 1998, Ziff-Davis Inc.'s top 20
advertising customers accounted

                                      34
<PAGE>

for approximately 37.1% of its advertising revenue. These advertising clients,
and our other advertising clients, may not continue to use our services to the
same extent, or at all, in the future. A significant reduction in advertising
by one or more of Ziff-Davis Inc.'s largest clients would have a material
adverse effect on our profits and liquidity.

Ziff-Davis Inc.'s Revenue Is Dependent On Certain Publications And Trade Shows

  Certain of our publications have represented a significant portion of our
historic revenue. We expect that such publications will continue to do so in
the future. Three of our business publications, PC Magazine, Computer Shopper
and PC Week, accounted for approximately 48% of our publishing revenue in 1998.
Although we believe we have a diversified portfolio of special interest
publications and are not dependent on any single publication, a significant
decline in the performance of any of these publications could have a material
adverse effect on our profits and liquidity.

  Certain of our trade shows and conferences have represented a significant
portion of our historic revenue. We expect that such trade shows and
conferences will continue to do so in the future. COMDEX/Fall accounted for 32%
of our trade show and conference revenue in 1998. Although we believe we have a
diversified portfolio of trade shows worldwide, a significant decline in the
performance of COMDEX/Fall could have an adverse effect on our profits and
liquidity.

Ziff-Davis Inc.'s Revenue Is Seasonal And This May Affect Its Quarterly
Operating Results

  Our business is seasonal. Revenue typically reaches its highest level during
the fourth quarter of each calendar year. These seasonal trends materially
affect our quarter-to-quarter operating results. Thus, one quarter's operating
results are not indicative of what the following quarter's operating results
will be. This is largely due to the timing of our single largest trade show
event, COMDEX/Fall, and the general increase in publishing revenue in the
fourth quarter due to increased consumer buying activity during the holiday
season. We cannot assure you that COMDEX/Fall will continue to be successful or
that our fourth quarter revenue will continue to be higher than revenue for our
other quarters.

Ziff-Davis Inc. Has Historical Net Losses And There Is No Assurance It Will
Report Net Income In The Future

  We and our predecessor have incurred significant net losses in the past and
we cannot assure you that we will report net income in the future. For more
information on our net losses, see Ziff-Davis Inc.'s. Selected Historical
Consolidated Financial and Other Data and Consolidated Financial Statements
appearing elsewhere in this prospectus.

To Remain Competitive, Ziff-Davis Inc. Must Constantly Expand And Develop New
Products And Services. This Is Inherently Risky And Expensive

  Our success depends in part on our ability to monitor rapidly changing
technologies and market trends and offer new publications, trade shows and
services, including online services, that address the needs of specific target
audiences. The process of internally researching and developing new products
and services and whether they will achieve market acceptance and profitability
can be risky and costly. We cannot assure you that our

                                       35
<PAGE>

efforts to introduce new, or assimilate acquired, publications, trade shows or
services will be successful or profitable. Costs to develop new products are
expensed as incurred. Accordingly, our profitability from year to year may be
adversely affected by the number and timing of new product launches.

  In February 1999, we purchased ZDTV from an affiliate at a purchase price of
$81.4 million plus the costs of funding its operations for January 1999. We
cannot assure you that ZDTV will ultimately obtain sufficient cable carriage
and commercial acceptance to be profitable.

Ziff-Davis Inc. May Be Adversely Affected By Fluctuations In Paper And Postage
Costs

  ZD's principal raw material is paper. Paper costs constitute a significant
expense, accounting for 15.2% of our total U.S. print publishing operating
expenses in 1997 and 16.3% in 1998. Paper prices have been volatile over the
past several years, rising from 1994 through 1996, declining in 1997 and
remaining relatively flat in 1998. Management anticipates that paper prices
will remain relatively stable in 1999. We do not use forward contracts and most
of our 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 ZD's future results of operations.

  Postage for magazine distribution is also one of ZD's significant expenses,
accounting for 11.3% of our total U.S. print publishing operating expenses in
1997 and 7.7% in 1998. Postage costs increase periodically and can be expected
to increase in the future. Management estimates postage costs will increase
approximately 3.5% in 1999. We may not be able to recover, in whole or in part,
paper or postage cost increases. Accordingly, significant cost increases could
have a material adverse effect on our profits and liquidity.

Ziff-Davis Inc. Faces Significant Competition In Its Various Businesses And If
It Is Unable To Effectively Compete, Its Profits And Liquidity Could Be
Materially And Adversely Affected

  We face significant competition with respect to our print publications, trade
shows and conferences and other technology information services. If we are
unable to compete effectively for advertisers, readers, exhibitors and/or
attendees, our profits and liquidity could be materially and adversely
affected.

  In our publishing business, we principally compete for advertising and
circulation revenue with publishers of other computer technology publications.
We also face broad competition from media companies that produce general
interest magazines and newspapers. 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. Overall competitive factors in publishing include product
positioning, editorial quality, circulation, price and customer service. In our
trade show and conference business, we compete 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.

Ziff-Davis Inc.'s Principal Vendors Are Consolidating And This May Adversely
Affect Its Business And Operations

  Our principal vendors include paper suppliers, printers, subscription
fulfillment houses and national newsstand distributors. Each of these
industries is currently experiencing consolidation among their principal
participants. Such consolidation may result in:

  . decreased competition, which may lead to increased prices,

  . interruptions and delays in services provided by such vendors and

  . greater dependence on certain vendors.

  Such factors could adversely affect our results of operations. One printing
company accounted for approximately 50% of our U.S.-based publications'
manufacturing expenditures in 1997 and 1998. While we believe there are
adequate alternatives available, an interruption or delay in service from, or
the loss of, this printer could have a material adverse effect.

Ziff-Davis Inc. Is Exposed To A Number Of Risks Associated With International
Markets That Could Adversely Affect Its Business And Operations

  One component of our growth strategy is to further expand into international
markets. There are certain risks inherent in doing business in international
markets. For example:

  . the uncertainty of product acceptance by different cultures,

  . the risks of divergent business expectations,

  . difficulties in finding appropriate foreign licensees or 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 our future international operations and, consequently, on our
profits and liquidity.

Ziff-Davis Inc. Is A Defendant In Several Lawsuits, Which Could Materially And
Adversely Affect Its Business And Operations

  In connection with the initial public offering of our existing common stock
and the repricing of certain stock options, we have been named as a defendant
in several lawsuits. While we believe there are substantial defenses to all of
the claims, we cannot assure you that we will prevail. Defense costs and/or
settlement costs relating to these actions could be substantial, and the
defense of these actions may divert management's attention and resources. If
the plaintiffs prevail in these actions, any judgments awarded by the courts
could have a material adverse effect on our liquidity. For more information
regarding these lawsuits, see "ZDNet Description of Business--Legal
Proceedings".

Ziff-Davis Inc.'s Computer Systems, And Those Of Others On Whom It Relies, May
Not Achieve Year 2000 Readiness

  Programming codes in existing computer systems and software may not reliably
recognize date-sensitive information when the calendar year changes to 2000.
Systems or software that do not properly recognize such information could
generate erroneous data or fail. We are in the process of identifying and
testing our computer systems and software for Year 2000 readiness. In addition,
we are in the process of working with third parties on whom we rely for system
and database management to ensure Year 2000 readiness. We have not verified
that such third parties are Year 2000 compliant. We cannot assure you that our
systems or software, or third-party systems or software on which we rely, will
be Year 2000 compliant. Significant uncertainty exists concerning the potential
costs and effects associated with Year 2000 compliance. If Ziff-Davis Inc. or
any subscribers, advertisers, licensors, vendors or other third parties on whom
we rely experiences a Year 2000 compliance problem, this could have a material
adverse effect on our profits and liquidity. For more information on our Year
2000 readiness, see "Ziff-Davis Inc. Management's Discussion and Analysis of
Financial Condition And Results of Operations --Year 2000 Readiness Disclosure"
in this prospectus.

statements can be identified by the use of forward-looking terminology such as
"may", "will", "expect", "anticipate", "estimate", "continue", "plan" or other
similar words. These statements discuss future expectations, contain
projections of results of operations or of financial condition or state other
"forward-looking" information. When considering such forward-looking
statements, you should keep in mind the factors described in "Risk Factors" and
other cautionary statements appearing in Management's Discussion and Analysis
of Financial Condition and Results of Operations for each of Ziff-Davis Inc.,
ZD and ZDNet appearing elsewhere in this prospectus. Such risk factors and
statements describe circumstances which could cause actual results to differ
materially from those contained in any forward-looking statement.

            TRADING PRICES OF AND DIVIDENDS ON EXISTING COMMON STOCK

  There currently is no trading market for ZDNet stock.

  Our existing common stock, which we are not now offering, is traded on the
NYSE under the trading symbol "ZD". On March 23, 1999, the closing price per
share of existing common stock as reported on the NYSE Composite Tape was
$24.88. As of March 23, 1999, there were 103,108,291 shares of existing common
stock outstanding and 315 stockholders of record.

  The high and low sales prices of our existing common stock, as reported on
the NYSE Composite Tape, for that portion of the second quarter of 1998 since
our existing common stock began trading, for the third and fourth quarters of
1998 and the first quarter of 1999 are shown below.

                                USE OF PROCEEDS

  Based upon the initial public offering price of $19.00 per share of ZDNet
stock, we estimate that, after deducting underwriting discounts and expenses,
we will receive net proceeds from the initial public offering of ZDNet stock,
of $172.5 million, or $199.0 million if the underwriters fully exercise their
option to purchase additional shares. We will attribute the net proceeds from
1.5 million shares to ZDNet (estimated to be approximately $25.9 million), in a
manner analogous to a primary offering of common stock. We will attribute the
net proceeds from the remaining shares to ZD (estimated to be approximately
$146.6 million, or $173.1 million if the underwriters fully exercise their
overallotment option), in a manner analogous to a secondary offering of common
stock of a subsidiary owned by a parent. ZDNet will advance to ZD the net
proceeds attributed to ZDNet, and ZD will use those net proceeds, together with
the net proceeds attributed to ZD, to reduce outstanding indebtedness under our
revolving credit facility. The indebtedness owed under our revolving credit
facility was, at March 23, 1999, $230 million, bore interest at that time at a
weighted average interest rate of approximately 7.799% based on various LIBOR
rates and matures on March 31, 2005. The advance of cash by ZDNet to ZD will be
treated as an inter-group revolving credit advance and will bear interest at
the rate at which we could borrow such funds on a revolving credit basis. Since
that rate is based on a spread to LIBOR rates as in effect from time to time,
it is not possible to quantify the interest rate in advance.

<PAGE>

                                DIVIDEND POLICY

  We currently intend to retain all of our earnings to finance our operations,
repay indebtedness and fund future growth. We do not expect to pay any
dividends on ZDNet stock for the foreseeable future.

  Although certain of our debt instruments currently prohibit the payment of
dividends, and in any event, as stated above, we do not expect to pay any
dividends for the foreseeable future on either series of common stock, we will
otherwise be permitted to pay dividends on:

  . ZD stock out of the assets of Ziff-Davis Inc. legally available for the
    payment of dividends under Delaware law, but the total amounts paid as
    dividends on ZD stock cannot exceed the Available Dividend Amount for ZD
    and

  . ZDNet stock, out of the assets of Ziff-Davis Inc. legally available for
    the payment of dividends under Delaware law (and transfer corresponding
    amounts to ZD in respect of its retained interest in ZDNet), but the
    total of the amounts paid as dividends on ZDNet stock and the
    corresponding amounts transferred to ZD in respect of its Retained
    Interest in ZDNet cannot exceed the Available Dividend Amount for ZDNet.

  The "Available Dividend Amount" for ZD or ZDNet, as the case may be, is based
on the amount that would be legally available for the payment of dividends
under Delaware law if ZD and ZDNet were each a separate Delaware corporation.
For more information on the "Available Dividend Amount" for ZD and ZDNet, see
"Description of Capital Stock--Dividends". We expect that determinations to pay
dividends on ZDNet stock would be based primarily upon the financial condition,
results of operations, capital requirements, any restrictions contained in
financing or other agreements binding upon us and such other factors as the
board of directors deems relevant.

     assuming the underwriters do not exercise their option to purchase
     additional shares,

  .  the application of the net proceeds as described under "Use of Proceeds"
     and

  .  the re-classification of existing common stock into ZD stock.

These tables should be read in conjunction with the Financial Statements and
the notes thereto included in this prospectus.

                                    DILUTION

  At December 31, 1998, ZDNet had a net tangible book value of approximately
$21,768,000 or $0.30 per share equivalent. Net tangible book value per share
equivalent at any date represents the amount of ZDNet's total tangible assets
minus total liabilities divided by the Total Number of Notional ZDNet Shares
Deemed Outstanding. After giving effect to the sale of 10,000,000 shares of
ZDNet stock offered hereby at the initial public offering price of $19.00 per
share and the application of the estimated net proceeds allocated to ZDNet, the
pro forma net tangible book value of ZDNet would have been approximately
$47,643,000 or $0.67 per share equivalent. Thus, under these assumptions,
purchasers of ZDNet stock offered by this prospectus will pay $19.00 per share
and will receive shares with a net tangible book value per share equivalent of
$0.67, which represents an immediate dilution of $18.33 per share.

  The following table illustrates this per share dilution:

  The foregoing computation of dilution excludes an aggregate of approximately
10,026,000 shares of ZDNet stock purchasable at $4.29 per share upon the
exercise of outstanding employee stock options.

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

Revenue

  ZDNet's revenue consists of advertising revenue and revenue from
subscription-based fees and services. Advertising revenue consists primarily of
revenue derived from the sale of advertisements on pages delivered to users of
ZDNet's Internet sites. ZDNet recognizes the delivery of a single view of an
advertisement as an "impression". Advertising revenue is derived principally
from arrangements with ZDNet's advertising customers that provide for a
guaranteed number of impressions. Advertising rates vary depending primarily on
the total number of guaranteed impressions purchased, the length of the
advertiser's commitment, the location in which the advertisements are displayed
and the type of advertising. Advertising revenue is recognized in the period in
which the advertisements are delivered. For contracts/campaigns that are longer
than one accounting period, the revenue from the contract/campaign is
recognized ratably over the term of the contract/campaign.

  Revenue from barter transactions is recognized during the period in which
advertisements are displayed. Barter transactions are recorded at the lower of
estimated fair value of goods or services received or the estimated fair value
of advertising given. To date, barter transactions have been immaterial to
revenue.

  During 1995 and part of 1996, ZDNet was focused on generating revenue from
subscription-based fees and services. This revenue is generated primarily by
charging monthly membership fees to provide access to product reviews, software
reviews and shareware. During 1996, ZDNet shifted the focus of the business
model from the generation of subscription-based fees and services to the
generation of advertising revenue.

  As a result of this shift, ZDNet's advertising revenue increased from 6.0% of
total revenue for the year ended December 31, 1995 to 86.0% of total revenue
for the year ended December 31, 1998. Over this period subscription-based fees
and services decreased correspondingly as a percentage of revenue.

  No single advertiser accounted for more than 5.0% of ZDNet's total revenue
for the year ended December 31, 1997 or 1998. ZDNet's top 20 advertisers
accounted for 29.3% and 39.9% of total revenue for the years ended December 31,
1997 and 1998, respectively.

Cost of Operations

  Costs of production and content include costs to produce and edit content on
ZDNet's Internet sites as well as technical costs incurred to maintain ZDNet's
Internet sites. ZD provides certain editorial content and brand-marketing
services to ZDNet for which ZDNet pays a royalty to ZD based on revenue. This
charge is also included in costs of production and content. See Note 4 to
ZDNet's Combined Financial Statements in this prospectus.

                                       46
<PAGE>

  The principal selling, general and administrative expenses of ZDNet are
payroll, sales commissions and related expenses, marketing and promotion. Ziff-
Davis Inc. provides certain selling, general and administrative services and
shared services on a centralized basis and the costs of these central services
are allocated between ZD and ZDNet. See Note 4 to ZDNet's Combined Financial
Statements in this prospectus.

  ZDNet also incurs a substantial amount of amortization expense related to
intangible assets created as a result of the December 21, 1994 and February 29,
1996 acquisitions of Ziff-Davis Inc.'s predecessors by Forstmann Little and Co.
and SOFTBANK Corp., respectively. The February 1996 acquisition created
$72.7 million of intangible assets for ZDNet. In addition, $5.5 million of
intangible assets were created by ZDNet's January 1997 acquisition of a 70%
equity interest in GameSpot, Inc., formerly SpotMedia Communications, Inc.

Factors Affecting Future Periods

  ZDNet'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 expenditures by ZDNet's advertisers, the
extent to which merchants elect to advertise using online media and competition
among other technology marketers.

  Accordingly, ZDNet may experience fluctuations in revenue from period to
period. Marketing expenditures by technology companies can also be affected by
factors affecting the technology industry generally, including pricing
pressures and temporary surpluses of inventory. Revenue and profitability are
also influenced by product mix, the timing and frequency of ZDNet's new product
launches in new markets and acquisitions.

  ZDNet has an extremely limited operating history upon which to base an
evaluation of ZDNet's prospects. ZDNet's prospects must be considered in light
of the risks, expenses and difficulties frequently encountered by start-up
companies in the new and rapidly evolving market for Internet products, content
and services. ZDNet's revenue and cost of operations have grown substantially
and ZDNet has incurred cumulative net losses since inception. These losses
reflect substantial expenditures to develop, launch and acquire ZDNet's
Internet sites and services. ZDNet believes that newly launched sites and
services require a certain period of growth before they begin to achieve
adequate revenue to support their operation.

  ZDNet must, among other things, effectively develop new relationships and
maintain existing relationships with its advertisers, their advertising
agencies and other third parties, provide original and compelling content to
Internet users, develop and upgrade its technology, respond to competitive
developments and attract, retain and motivate qualified personnel. There can be
no assurance that ZDNet will succeed in addressing such risks and the failure
to do so could have a material adverse effect on ZDNet's business, financial
condition or results of operations. Additionally, ZDNet's limited operating
history makes the prediction of future operating results difficult or
impossible, and there can be no assurance that ZDNet's revenue will increase or
even continue at its current level, or that ZDNet will

                                       47
<PAGE>

achieve or maintain profitability or generate cash from operations in future
periods. Since inception, ZDNet has incurred significant losses and, for the
period from February 29, 1996 to December 31, 1998, had accumulated a deficit
of $46.0 million. ZDNet may continue to incur losses in the future.

  ZDNet expects to recognize compensation expense of approximately $13.4
million as a result of certain options granted on December 21, 1998 and January
29, 1999. Such compensation expense will be recognized over the vesting period
of the options. The 1999 compensation expense related to these options is
expected to be approximately $3.3 million. See Note 11 to ZDNet's Combined
Financial Statements in this prospectus.

  ZDNet expects to acquire the remaining 30% interest in GameSpot in exchange
for ZDNet stock valued at $9 million, based on the initial public offering
price; provided that, the stockholders of GameSpot will not receive less than
600,000 shares of ZDNet stock. At a price of $19.00 per share, this acquisition
will result in additional annual amortization of approximately $1.3 million per
year. The effect of this acquisition and the shares expected to be issued in
connection therewith are not reflected elsewhere in this prospectus.

  For a discussion of other factors that may affect results, see "Risk
Factors--Risk Factors Relating to ZDNet".

Presentation of Financial Information

  ZDNet is comprised of certain operations which were acquired at various times
and completed a reorganization in May 1998. See Note 1 to ZDNet's Combined
Financial Statements in this prospectus.

Results of Operations

  The table below presents the results of ZDNet as if the assets and operations
acquired by affiliates of Ziff-Davis Inc. on February 29, 1996 (as described in
Note 1 to the ZDNet Combined Financial Statements in this prospectus) had been
acquired on January 1, 1995. Purchase accounting adjustments relating to that
acquisition have been reflected through pro forma amortization and interest and
income tax adjustments, as described in note (1) to the table. Although the
1996 presentation is not in accordance with generally accepted accounting
principles, management believes it presents the most meaningful basis of
comparison. The financial information presented below may not necessarily
reflect the results of operations which would have occurred had the February
29, 1996 acquisition been completed on January 1, 1995.

(1) The February 29, 1996 acquisition gave rise to different bases of
    accounting for the period after the acquisition as compared to the period
    prior to the acquisition. The above numbers assume that the acquisition
    took place on January 1, 1995; therefore amortization of intangible assets
    and net loss have been increased by $323,000 and $194,000, respectively,
    for the year ended December 31, 1996.

(2) "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 ZDNet's operating performance or to cash
    flows as a measure of liquidity. Although ZDNet believes that EBITDA is a
    standard measure commonly reported and widely used by analysts, investors
    and other interested parties in the media industry, the EBITDA presented
    for ZDNet may not be comparable to similarly titled measures reported by
    other companies.

Year ended December 31, 1998 compared with the year ended December 31, 1997

 Revenue, net

  Net revenue increased 74% to $56.1 million for the year ended December 31,
1998 from $32.2 million for the year ended December 31, 1997. Revenue from
advertising was 86% of net revenue for the year ended December 31, 1998
compared to 73% for the year ended December 31, 1997.

  Revenue from advertising increased 104% to $48.1 million for the year ended
December 31, 1998 from $23.6 million for the year ended December 31, 1997. The
increase in advertising revenue was attributed to an increase in volume as both
the number of advertisers and the average monthly revenue per advertiser
increased. Subscription-based fees and services decreased by 7% to $8.0 million
for the year ended December 31, 1998 from $8.6 million for the year ended
December 31, 1997.

 Cost of operations

  Production and content.  Production and content expenses were $26.2 million
or 46% of net revenue for the year ended December 31, 1998, compared to $23.5
million or 73% of net revenue for the prior year. The absolute dollar increase
in production and content charges was due to an increase in ZD's revenue-based
royalty charge to ZDNet, as well as an increase in production costs to support
higher user traffic levels and increased editorial costs associated with the
launch of new content areas. The cost of production and content decreased as a
percentage of revenue primarily due to economies of scale. ZDNet expects this
trend to continue. Royalty payments to ZD were $2.8 million and $1.6 million
for the years ended December 31, 1998 and 1997, respectively.

                                       50
<PAGE>

  Selling, general and administrative expenses.  Selling, general and
administrative expenses were $31.0 million or 55% of net revenue for the year
ended December 31, 1998, compared to $23.5 million or 73% of net revenue for
the year ended December 31, 1997. The absolute dollar increase was primarily
due to increased personnel and services required to support the growth of
ZDNet, offset to some extent by the cessation of commission payments to
SOFTBANK Interactive Marketing Inc., as ZDNet sales and marketing teams
replaced SOFTBANK Interactive in these functions. Sales and marketing costs
were $21.2 million or 38% of net revenue for the year ended December 31, 1998
compared to $15.9 million or 49% of net revenue for the year ended December 31,
1997. ZDNet intends to continue to increase spending in absolute dollars on
sales and marketing and intends to launch a print ad campaign in the future.
Sales and marketing expenses are incurred both to drive traffic to ZDNet's Web
site and to increase the number of advertisers and advertising sales. Included
in the sales and marketing costs was an allocation from Ziff-Davis Inc.
relating to certain selling, general and administrative services and shared
services provided on a centralized basis amounting to $0.9 million and $0.5
million for the years ended December 31, 1998 and 1997, respectively.

  Administrative and overhead costs were $9.7 million or 17% of net revenue for
the year ended December 31, 1998 compared to $7.6 million or 23% of net revenue
for the year ended December 31, 1997. Included in administrative and overhead
costs was an allocation of the cost of certain Ziff-Davis Inc. services
provided on a centralized basis amounting to $5.1 million and $3.4 million for
the years ended December 31, 1998 and 1997, respectively. The selling, general
and administrative costs decreased as a percentage of revenue primarily due to
economies of scale. ZDNet expects this trend to continue.

  Depreciation.  Depreciation expense was $2.0 million for the year ended
December 31, 1998 compared to $1.5 million for the year ended December 31,
1997. The increase related primarily to the increased capital expenditures made
by ZDNet for equipment necessary to expand its network and infrastructure in
order to support its continued growth.

  Amortization of intangible assets.  Amortization of intangible assets was
$4.4 million for the year ended December 31, 1998 compared to $6.2 million for
the year ended December 31, 1997. The decrease in amortization related to the
intangible assets of advertising and subscription lists becoming fully
amortized as of March 1, 1998. This resulted in only two months of the related
amortization being included in the year ended December 31, 1998 versus twelve
months amortization included in the year ended December 31, 1997. Annual
amortization expense related to the remaining goodwill balance will be
approximately $4.1 million before giving effect to any future increase in
goodwill.

   Minority interest

  The minority interest of $0.1 million in 1998 and $0.4 million in 1997
represented losses attributed to the holders of the minority interest in
GameSpot.


                                       51

   Income taxes

  Losses which were incurred prior to the completion of Ziff-Davis Inc.'s
reorganization on May 4, 1998, are non-deductible for Ziff-Davis Inc. as ZDNet
was under the ownership of MAC Inc. As such, ZDNet recorded income tax expense
of $0.5 million for the year ended December 31, 1998, primarily resulting from
taxable income being generated during the third and fourth quarters of 1998,
representing an effective tax rate of (6.9%). The effective rate in 1997 was
significantly lower than the statutory rate of 35.0% due to the substantial
level of non-deductible expenses which were incurred while ZDNet was owned by
MAC Inc.

   Net loss

  As a result of the items described above, ZDNet's net loss decreased to $7.9
million from $21.2 million for the years ended December 31, 1998 and 1997,
respectively.

   EBITDA

  EBITDA for the year ended December 31, 1998 was a loss of $0.9 million
compared to a loss of $14.4 million for the same period in 1997. The
improvement was due to substantially increased revenue, offset to some extent
by higher production and content costs and selling, general and administrative
expenses.

Year ended December 31, 1997 compared with Pro Forma Year ended December 31,
1996

 Revenue, net

  Net revenue increased 69% to $32.2 million for the year ended December 31,
1997 from $19.1 million for the pro forma year ended December 31, 1996. An
increasing percentage of ZDNet's net revenue was derived from advertising for
the year ended December 31, 1997, accounting for 73% of net revenue, compared
to 37% for the same period in 1996. The increased percentage of net revenue
derived from advertising in the later period reflects a continuation of ZDNet's
strategic shift from a business model based on subscription-based fees and
services to one based on advertising.

  Revenue from advertising increased 228% to $23.6 million for year ended
December 31, 1997 from $7.2 million for the pro forma year ended December 31,
1996. The increase in advertising revenue was attributable to increases in the
number of advertisers, the average expenditures per advertiser and increasing
advertising rates. The increase was evenly attributable to rate and volume
increases. Subscription-based fees and services decreased by 28% to $8.6
million from $11.9 million from the same period in 1996.

 Cost of Operations

  Production and content. Production and content expenses were $23.5 million or
73% of net revenue for year ended December 31, 1997, compared to $16.7 million
or 87% of net revenue for the pro forma year ended December 31, 1996. The
absolute dollar

                                       52
<PAGE>

increase in production and content charges was due to an increase in Ziff-Davis
Inc.'s revenue based royalty charge to ZDNet, as well as an increase in
production costs to support higher user traffic levels, and increased editorial
costs associated with the launch of new content areas. The cost of production
and content decreased as a percentage of revenue primarily due to economies of
scale. Royalty charges from ZD were $1.6 million and $1.0 million for the year
ended December 31, 1997 and the pro forma year ended December 31, 1996,
respectively.

 Selling, general and administrative expenses.  Selling, general and
administrative expenses were $23.5 million or 73% of net revenue for the year
ended December 31, 1997, compared to $15.1 million or 79% of net revenue for
the pro forma year ended December 31, 1996. The absolute dollar increase in
selling, general and administrative expenses was due to higher sales commission
costs paid to SOFTBANK Interactive and to the initial hiring of the existing
ZDNet sales and marketing teams. SOFTBANK Interactive was the exclusive sales
team for ZDNet prior to 1997. Sales and marketing costs were $15.9 million or
49% of net revenue for the year ended December 31, 1997 compared to
$11.0 million or 57% of net revenue for the pro forma year ended December 31,
1996. Included in sales and marketing costs was an allocation from Ziff-Davis
Inc. relating to certain selling, general and administrative services and
shared services provided on a centralized basis amounting to $0.5 million for
the year ended December 31, 1997. There was no such charge for the pro forma
year ended December 31, 1996.

  Administrative and overhead costs were $7.6 million or 23% of net revenue for
the year ended December 31, 1997 from $4.1 million or 21% of net revenue for
the pro forma year ended December 31, 1996. Included in administrative and
overhead costs was an allocation of the cost of certain Ziff-Davis Inc.
services provided on a centralized basis amounting to $3.4 million and $2.7
million for the year ended December 31, 1997 and the pro forma year ended
December 31, 1996, respectively. Selling, general and administrative expenses
decreased as a percentage of revenue primarily due to economies of scale.

 Depreciation and amortization.  Depreciation and amortization expense was $1.5
million for the year ended December 31, 1997, compared to $0.7 million for the
pro forma year ended December 31, 1996. The increase in depreciation expense
primarily related to the increased capital expenditures made by ZDNet for
equipment necessary to expand its network and infrastructure in order to
support its continued growth.

 Amortization of intangible assets.  Amortization of intangible assets was $6.2
million for the year ended December 31, 1997 compared to $5.7 million for the
pro forma year ended December 31, 1996. In February 1997, ZDNet purchased a 70%
interest in GameSpot, which created intangible assets of approximately $5.5
million. The 1997 period included approximately $0.5 million of amortization
related to this acquisition.

 Minority interest

  The minority interest of $0.4 million for the year ended December 31, 1997,
represents losses attributed to the holders of the minority interest in
GameSpot, which was acquired in January 1997.

                                       53
<PAGE>

 Income taxes

  The 1997 income tax benefit of $0.8 million compares to a pro forma income
tax provision of $1.1 million in 1996. The benefit represents an effective tax
rate of approximately 3.8% and 5.6%, respectively, which is significantly less
than the federal statutory rate of 35.0% because ZDNet has a substantial level
of non-deductible expenses, as losses which were incurred while ZDNet was under
MAC ownership are non-deductible to Ziff-Davis Inc. As such, ZDNet does not
reflect any tax benefits associated with those losses.

 Net loss

  As a result of the items described above, ZDNet's net loss increased to $21.2
million for the year ended December 31, 1997 from $17.9 million for the pro
forma year ended December 31, 1996.

 EBITDA

  EBITDA for 1997 was a loss of $14,400,000 compared to a loss of $12,601,000
for the pro forma year ended December 31, 1996. The decrease was primarily due
to higher production and content costs and selling, general and administrative
expenses partially offset by increased revenue.

Liquidity and Capital Resources

 Funding from ZD

  In the financial statements of ZD and ZDNet, whenever ZDNet had a cash need,
other than cash needs of ZDNet's foreign operations or cash needs of ZDNet's
operations that are not wholly owned, that cash need was funded by ZD and
accounted for as a capital contribution (i.e., as an increase in ZDNet's
division equity and ZD's retained interest in ZDNet). Accordingly, no interest
expense has been reflected in the financial statements of ZDNet. Each of ZD and
ZDNet is sometimes referred to herein as a "group". After the date on which
ZDNet stock is first issued, Ziff-Davis Inc. will account for all cash
transfers from ZD or ZDNet to or for the account of the other, other than
transfers in return for assets or services rendered or transfers in respect of
ZD's retained interest that correspond to dividends paid on ZDNet stock, as
inter-group revolving credit advances. These advances will bear interest at the
rate at which Ziff-Davis Inc. could borrow such funds on a revolving credit
basis as the board of directors determines in its sole discretion. However, the
board of directors has the discretion to determine that a given transfer or
type of transfer should be accounted for as a long-term loan, a capital
contribution increasing ZD's retained interest in ZDNet or a return of capital
reducing ZD's retained interest in ZDNet.

  For a discussion about the terms on which Ziff-Davis Inc. can now borrow on a
short-term basis, see "Ziff-Davis Inc. Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources--Credit Facility". There is no assurance, however, that ZDNet will
continue to be able to obtain sufficient funding from ZD. For a discussion of
the discretion of the board of directors regarding

Relating to ZDNet Stock--Under Its Current Policies The Board of Directors Has
Sole Discretion Concerning Various Cash Management Matters".

 Sources and uses of cash

  Cash and cash equivalents were $0.3 million at December 31, 1998, an increase
of $0.3 million from $0.0 million at December 31, 1997. The increase was due to
the factors discussed below:

  Cash used by operations was $4.5 million for the year ended December 31, 1998
compared to $15.3 million for the year ended December 31, 1997. The improvement
from 1998 to 1997 was due primarily to a reduction in net loss. The loss for
the year ended December 31, 1998 was $7.9 million compared to $21.2 million for
the same period in 1997.

  Cash used by investing activities for the year ended December 31, 1998
totaled $9.5 million and $5.4 million for the year ended December 31, 1997.
Cash used for capital expenditures for the year ended December 31, 1998
increased by $2.1 million to $4.5 million from $2.4 million for the year ended
December 31, 1997. ZDNet intends to continue to invest in equipment as
necessary to support the increasing user traffic. Capital expenditures on
equipment is expected to be approximately $4.0 million in 1999. In addition, in
July 1998, ZDNet invested $5.0 million in preferred stock of Deja News, Inc.,
an Internet discussion group. During the year ended December 31, 1997, ZDNet
spent approximately $3.0 million to acquire a 70% interest in GameSpot.

  Cash provided by financing activities decreased to $14.3 million for the year
ended December 31, 1998 from $20.7 million for the year ended December 31,
1997, reflecting the improved operating performance of ZDNet. As discussed
under "--Funding from ZD" above, all funding from ZD was accounted for as a
capital contribution.

Seasonality

  Historically, ZDNet's business has been seasonal as a significant portion of
annual revenue has occurred in the fourth quarter. This fluctuation is a result
of seasonal changes common to the media industry. The following table sets
forth certain unaudited quarterly combined statement of operations data for
each of the eight quarters in the period ended December 31, 1998. In the
opinion of Ziff-Davis Inc.'s management, this unaudited information has been
prepared on a basis consistent with the audited Combined Financial Statements
of ZDNet in this prospectus 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.

(1) "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 ZDNet's operating performance or to cash
    flows as a measure of liquidity. Although Ziff-Davis Inc. believes that
    EBITDA is a standard measure commonly reported and widely used by analysts,
    investors and other interested parties in the media industry, the EBITDA
    presented for ZDNet may not be comparable to similarly titled measures
    reported by other companies.

Year 2000 Readiness Disclosure

  During 1997, Ziff-Davis Inc., including the businesses comprising ZDNet,
began a review of its computer systems and software to identify systems and
software which might malfunction due to misidentification of the Year 2000.
Ziff-Davis Inc. is using both internal and external resources to identify,
test, correct and reprogram systems and software for Year 2000 readiness.

  At December 31, 1998, Ziff-Davis Inc. was in the research and validation
phase of its Year 2000 project for information technology or IT, systems and
non-IT systems. This phase consists of research and validation of all
infrastructure, hardware and software, including platform, wide-area network
and local-area network components. Research for non-IT systems includes
identifying systems that include embedded technology, such as micro-
controllers, which are not Year 2000 compliant.

  Ziff-Davis Inc. has identified critical systems and applications that will
either be validated for compliance though formal documentation, through vendors
or through testing. Ziff-Davis Inc. will enter the testing phase of its
infrastructure, hardware, software and databases in the first quarter of 1999
and plans to complete such phase by September 1, 1999. Contingency plans will
be developed for any systems or platforms that are known to be non-compliant as
of September 1, 1999.

  Some of Ziff-Davis Inc.'s computer systems and databases, including its
subscription fulfillment and payroll systems, are managed by third parties
under contractual arrangements. Ziff-Davis Inc. currently has no Year 2000
compliance problems known to it relating to third parties. Ziff-Davis Inc. has
requested those third parties with which Ziff-Davis Inc. has material
relationships in the first quarter of 1999 to advise it as to whether such
third parties anticipate difficulties in addressing Year 2000 compliance
problems, and if so, the nature of such difficulties. Ziff-Davis Inc.
anticipates that such inquiries will be completed by April 30, 1999.

  In addition, Ziff-Davis Inc. will develop contingency plans during the second
half of 1999 in order to compensate for any disruption or downtime that could
result from a Year 2000 compliance problem. Ziff-Davis Inc. plans to replace IT
and non-IT systems that it determines are not Year 2000 compliant prior to
October 1, 1999 in order to minimize any risk of a Year 2000 compliance
problem.

  Ziff-Davis Inc. has incurred remediation costs associated with its Year 2000
readiness efforts. These remediation costs have been incurred in connection
with replacement of systems and hardware, modification of software and
consulting costs related to Year 2000 solution providers. The costs to address
Year 2000 issues which have been included in the general and administrative
expenses of Ziff-Davis Inc. have not been tracked separately and are therefore
not determinable. However, management believes these expenses have been
substitutive rather than incremental to the recurring level of general and
administrative expenses. Total capitalized costs incurred in the replacement of
systems in connection with Ziff-Davis Inc.'s Year 2000 readiness efforts as of
December 31, 1997 and 1998 were

                                       57
<PAGE>

$1.7 million and $3.8 million, respectively. Ziff-Davis Inc. estimates that it
will incur an additional $3.8 million during 1999 related to its Year 2000
readiness efforts.

  Ziff-Davis Inc. expects to complete testing and replacement of critical
systems by the beginning of the fourth quarter of 1999. Ziff-Davis Inc.'s
estimate of ZDNet's most reasonably likely "worst case scenario" would be the
failure of its internal applications and systems that process and store certain
information and data. Ziff-Davis Inc. would resolve the failure of such
applications and systems one by one and management of Ziff-Davis Inc. does not
believe that the impact on its critical systems would be material. However, if
Ziff-Davis Inc. or any subscribers, advertisers, licensors, vendors or other
third parties on whom it relies experiences a Year 2000 compliance problem,
this could have a material adverse effect on ZDNet's profit and liquidity.

Recently Issued Accounting Pronouncement

  SFAS No. 133 Accounting for Derivative Instruments and Hedging Activities
issued in June 1998 establishes accounting and reporting standards for
derivative instruments and for hedging activities and is effective for all
fiscal quarters of fiscal years beginning after June 15, 1999. Ziff-Davis Inc.
does not expect the adoption of SFAS No. 133 to have a material impact on the
ZDNet's results of operations.

  ZDNet expects to adopt the above statement beginning with its 2000 financial
statements.

Industry Background

 Growth Of The Internet And Demand For Technology-Related Content

  The Internet has emerged as a global mass medium, enabling millions of people
to access and share information and conduct business electronically. Forrester
Research, Inc. estimates that the number of adult Web users will reach 51
million in the U.S. by the end of 1998 and will grow to 99 million by the end
of 2001. Major factors driving this growth include the increasing familiarity
and acceptance of the Internet by businesses and consumers, the increasing
number of personal computers in homes and offices, the ease, speed and lower
cost of Internet access and improvements in network infrastructure.

  As the Internet gains acceptance as an advertising and commerce medium and
Internet use continues to grow, technology will play an increasing role in
everyday life. According to Dataquest, worldwide end user spending for
information technology products and related services is expected to be
approximately $2 trillion in 1999 and grow 10% to 15% annually over the next
three years. With the growth of the Internet and the widespread use of personal
computers, cellular phones, pagers and personal digital assistants, technology
has become an area of broad general interest. Users of technology products and
services confront an increasingly complex marketplace due to the rapid pace of
technological change and the frequent introduction of new products and
services. The prevalence of technology and the growing number of technological
choices heighten the demand for up-to-date, comprehensive information about
technology-related products and services.

 Advertising And Commerce On The Internet

  As the Internet and the technology industry continue to grow, the value of
the Internet to advertisers and merchants can be expected to increase as a
result of:

  . the growth in the number of Web users,

  . the Internet's global reach,

  . the attractive demographic profile of Web users,

  . the interactive nature of the medium,

  . the increased willingness of users to conduct transactions online and

  . the ability to effectively target user groups, customize promotions and
    measure Web usage and viewer demographics.

  ZDNet believes these characteristics allow Internet advertisers to build
valuable customer relationships through targeted advertising and sales
campaigns. The overall market for advertising on the Internet was approximately
$900 million in 1997 and $1.3 billion in the first nine months of 1998, as
measured by the Internet Advertising Bureau. According to Forrester Research,
Inc., advertising spending on the Internet will exceed $4 billion in the year
2000 and double to more than $8 billion by 2002.

                                       59
<PAGE>

  The Internet also provides an efficient means for merchants to sell their
products and services directly to consumers. Forrester Research, Inc. forecasts
that worldwide commerce revenue on the Internet will increase from
approximately $35 billion in 1998 to $1.4 trillion in 2003. Internet
transactions are expected to increase as merchants improve Web-based
transaction-processing technology and as consumers become more accustomed to
purchasing online.

  ZDNet believes Internet sites focused on technology are particularly well-
suited to promote advertising and commerce because they offer a large user base
with attractive demographics for technology and general consumer product
companies. Historically, technology-focused sites have attracted primarily
technology advertisers, which, according to InterMedia Advertising Solutions,
accounted for approximately 47% of all U.S. online advertising dollars during
the first nine months of 1998. Recently, many of the largest advertisers on
traditional media, including consumer product companies, automobile
manufacturers and travel-related companies, have expanded their use of Internet
advertising. Such consumer-related advertising accounted for 27% of all U.S.
online advertising in the third quarter of 1998 according to the Internet
Advertising Bureau, and ZDNet believes Internet advertising will become an
increasing percentage of consumer product companies' overall advertising
budgets in the future. Internet sites with well-recognized brand names that
focus on technology should be well-positioned to capitalize on emerging
Internet advertising and commerce opportunities.

The ZDNet Solution

  ZDNet's Web sites are designed to capitalize on the market opportunities
created by the increasing importance of technology, the emergence of the
Internet as a mass medium and the appealing demographics of technology-oriented
Web users. ZDNet focuses on content, community and commerce, enabling users to
research topics of interest, interact with other users, download software and
evaluate and purchase a wide range of products and services at a single
destination. Ziff-Davis Inc. was among the first content providers to focus its
efforts on the Internet, launching its zdnet.com service in the fall of 1994.
The ZDNet solution is based on the following distinguishing attributes:

 Broad-Based Comprehensive Technology And Internet-Related Content

  ZDNet's interconnected and easily navigable sites offer depth and breadth of
coverage on the technology industry as well as topics of general interest,
including financial information and general news. ZDNet divides its content
broadly into "channels" that focus on specific topics or audience groups. Over
60 sites can be reached through the zdnet.com home page or through their own
distinct domains, and sites are generally organized with similar navigation and
layout to ensure consistency throughout the network. ZDNet's online editorial
and technical staff of industry experts develops high-quality original content
specifically for online interactive use. ZDNet offers over 1,200 news stories
per month, 50,000 product listings, 30,000 product reviews and 34,000
downloadable programs. In addition, through ZDNet's relationship with ZD, ZDNet
has use of the content of all of ZD's

                                       60
<PAGE>

computer and technology publications, including PC Magazine, PC/Computing, PC
Week and Yahoo! Internet Life.

 Strong Community Affinity

  ZDNet has developed an extensive user community and encourages active
participation by enabling users to personalize their content and join user
groups based on common interests. ZDNet provides forums, chat groups and other
interactive online environments that allow users to express views and share
information. In addition, its industry personalities host interactive forums
that encourage user comments and feedback. To promote its community, ZDNet has
instituted a common registration system for chat, discussion and e-mail
capabilities. Registered users are able to access member-only software
downloads and are eligible for special offers such as discounted trial
enrollment in ZDU's online courses, which is part of ZD's education business.
ZDNet makes a variety of e-mail newsletters and alerts available to its users,
allowing subscribers to select those of interest. As of December 1998, ZDNet
had an e-mail newsletter subscription base of over 2.3 million and distributed
over 52 million e-mail newsletters and alerts to its users in that month.

 Attractive Environment For Advertising And Commerce

  ZDNet facilitates commerce on its sites by providing users with the ability
to evaluate, compare and purchase products and services and by providing
advertisers and merchants with access to a highly targeted user group with
attractive demographics. According to the Winter 1999 @Plan study, among users
of ZDNet's Internet sites:

  . 59% have college degrees,

  . 85% have an annual household income of at least $35,000, and 21% in
    excess of $100,000,

  . 49% use the Internet every day and

  . 56% purchased a product in the prior six months after gathering
    information on the Internet.

  In addition, ZDNet has developed an array of sales and marketing options,
such as banners, sponsorship wraps, buttons, text and graphical links, e-mail
sponsorships and custom microsites, that are designed to assist advertisers in
crafting unique and distinctive programs to target and reach their audiences.
ZDNet is also the first non-ad agency to win a prestigious "Creative Excellence
in Business Advertising" award, presented by the American Business Press.

 Relationship With ZD

  ZDNet derives many benefits from its relationship with ZD, including the
ability to leverage the ZD brand, use content from ZD publications and cross-
market across all of ZD's platforms. ZD publishes leading technology print
publications, such as PC Magazine, PC/Computing, PC Week and Yahoo! Internet
Life, produces leading trade shows and conferences, such as COMDEX,
NetWorld+Interop and Seybold Seminars, operates ZDTV,

                                       61
<PAGE>

a 24-hour cable television network, and maintains well-recognized market
research and education platforms, such as ZDU. For over a decade, the "Ziff-
Davis" name has been a leading brand associated with technology content.

The ZDNet Strategy

  ZDNet's objective is to be the leading online content site focused on
technology products and services for users and the preferred online platform
for advertisers and merchants. The key elements of ZDNet's strategy are:

 Continue To Offer Differentiated Technology And Internet-Related Content

  ZDNet will continue to provide comprehensive and authoritative coverage of
the technology field in order to attract users and increase the value of its
sites to advertisers and merchants. Based on market research and user traffic
and feedback, ZDNet will continue to identify technology trends and develop
innovative sites that appeal to specific market segments and user interests. In
the past 12 months, ZDNet has introduced 16 new sites, or new areas within
existing sites, including special areas addressing Year 2000 issues, small
businesses, electronic commerce and technology-related careers.

 Grow The ZDNet Community

  ZDNet seeks to further grow its membership base by continuing to provide
interesting forums, chat groups and user groups, developing additional
interactive capabilities, promoting new online personalities and offering
insights from a broad range of experts. In response to these efforts, ZDNet's
registered user community has increased from 956,490 on December 31, 1997 to
1,844,571 on December 31, 1998, an increase of 93%. ZDNet also recently
launched ZDRewards, an online membership service which entitles subscribers to
receive a bundle of Ziff-Davis Inc. products and services, such as a
subscription to a ZD magazine or a semester of ZDU online classes, all for one
discounted price.

 Build ZDNet Brand Strength

  ZDNet seeks to reinforce its brand recognition and extend its reputation as a
leading site among users of technology information by continuing to leverage
the Ziff-Davis and ZDNet names. ZDNet's brand-building initiatives include
displaying the ZDNet brand on all ZDNet site pages, including those accessed
through the portals of its strategic partners,
providing consistent formats for easy navigation on all its sites and promoting
a common registration program for users. ZDNet plans to continue to promote the
ZDNet brand in ZD publications and events and to otherwise coordinate marketing
efforts with ZD.

 Increase Advertising And Commerce Revenue

  ZDNet seeks to increase revenue generated from advertising and commerce by
continuing to develop innovative content, growing its user community, expanding
its base of technology advertisers, attracting consumer and other advertisers
and facilitating commerce

                                       62
<PAGE>

opportunities. ZDNet continually refines its online tracking reports to better
enable advertisers and merchants to demonstrate their advertising
effectiveness, evaluate their marketing initiatives and increase the rate of
return on their advertising investments. ZDNet plans to increase the number of
its revenue-sharing commerce relationships with leading technology and consumer
product providers. ZDNet also plans to increase the number of product listings
on its ComputerShopper.com channel and expand its ability to facilitate
electronic commerce.

 Strengthen And Expand Strategic Alliances

  ZDNet seeks to increase brand awareness, traffic and revenue by entering into
strategic alliances with key Internet companies. ZDNet currently has alliances
with many of the Web's leading sites, including Yahoo!, Excite, MSNBC and Deja
News, and plans to establish new alliances as opportunities arise. As part of
these alliances, ZDNet typically provides selected branded content for its
partners' sites in return for a variety of benefits including revenue and links
back to ZDNet sites from the partner's site, providing ZDNet with access to a
broader base of consumers.

 Extend International Presence

  ZDNet had localized foreign language editions in more than 16 countries as of
December 31, 1998 and plans to continue to expand into selected overseas
markets through international launches as well as joint ventures and licensing
arrangements with local operating partners, as opportunities arise.

ZDNet Sites and Services

  ZDNet offers more than 60 interconnected and easily navigable sites focused
on providing comprehensive, authoritative and timely online technology content,
creating an active community environment for its users and providing
opportunities for commerce.

  ZDNet considers its content to be the most thorough and interesting content
on technology that is available online. ZDNet estimates that it currently
offers more than 300,000 pages of content on its interconnected sites where
users can research, evaluate, learn, interact, download and shop. ZDNet creates
original content using its own skilled and dedicated team of 149 editors,
online producers, developers and operations staff and also uses content from ZD
publications and various strategic alliance partners. ZDNet's content is
divided broadly into "channels" that aggregate information from a variety of
sources around a specific topic area or audience focus, thereby facilitating
accessibility. All channels can be reached through the main zdnet.com home page
or through their own distinct domains, making browsing and searching easy.

  ZDNet seeks to foster a sense of community and engage its users in an
interactive online experience where they can express opinions and share
information about technology-related products and issues. ZDNet offers a
variety of features and activities designed to facilitate its community growth
and build user loyalty and affinity. Users can

                                       63
<PAGE>

personalize the content they seek and join user groups with others who have
similar interests. In addition, users can activate the "talk-back" feature,
which allows them to state their views, and the "e-mail to a friend" feature,
which allows them to easily send articles of interest to others. During January
1999, ZDNet estimates that 275,000 e-mails were sent using the e-mail to a
friend feature. Many of ZDNet's channels provide moderated forums and chat
events on a variety of current news and segment topics and certain hosts of
these forums have become popular Internet personalities.

  ZDNet seeks to facilitate commerce on the Internet by combining information
about hardware and software products and services with direct access to
merchants. ZDNet's primary computer commerce site, ComputerShopper.com, was one
of the first Web shopping services to integrate comparative pricing, how-to
guides, buying tips, specifications, product reviews and multiple direct
purchasing sources. ComputerShopper.com currently displays products from more
than 113 merchants in over 88 product categories and enables shoppers to both
evaluate products and directly make purchases online.

seen by a combined circulation of approximately seven million primary readers
worldwide. ZD also produced over 50 trade shows and conferences worldwide on
technology and the Internet in 1998 with over two million estimated attendees.
Through ZDU, ZD provides online interactive instructor-led training to paid
subscribers. Through ZDTV, ZD offers the first 24-hour cable television channel

platforms.

marketing activities into one cohesive resource for print, trade show and

Strategic Alliances

  ZDNet's strategic alliances are important sources of content exchange,
revenue, brand visibility and increased user traffic. ZDNet has strategic
alliances with many of the Web's leading sites, including Yahoo!, Excite, MSNBC
and Deja News, pursuant to which selected ZDNet-branded content is displayed on
their sites in exchange for traffic, brand recognition, content or a percentage
of the revenue generated from those sites. These alliances are generally under
short-term contracts that expire in 1999, subject to renewal upon the agreement
of both parties.

  ZDNet is the exclusive high-technology content partner of MSNBC, one of the
Web's largest sites for general news and sports content. Under this arrangement
ZDNet licenses content and brands to MSNBC in exchange for the exclusive right
among online computer and technology content providers to use MSNBC's general
news content. ZDNet also recently started using Deja News' technology which
allows ZDNet's users to search Usenet and participate in online discussion
groups, including Usenet newsgroups. In addition, ZDNet content is distributed
by various Internet service providers such as AT&T WorldNet, MindSpring and
BellSouth to individual and corporate customers.

International

  Through wholly owned sites and joint ventures, ZDNet currently operates
localized versions of certain of its Web sites in the United Kingdom, Germany,
France and Australia. In addition, through licensing arrangements with non-U.S.
operators, localized foreign language versions of ZDNet's Web sites were
available as of December 31, 1998 in more than 12 additional countries,
including Japan, Italy, Latin America, Russia, South Africa, Spain and
Switzerland. In order to deliver high-quality content worldwide, each of
ZDNet's international Web sites offers content tailored specifically to its
local market in addition to content translated from ZDNet's U.S. Web sites. See
"Risk Factors--Risk Factors Relating to ZDNet--ZDNet Intends to Expand Its
International Operations And May Encounter A Number Of Problems Doing So. There
Are Also A Number of Risks Associated With International Operations That Could
Adversely Affect ZDNet's Business.

Advertising Sales And Marketing

  ZDNet derives the principal portion of its revenue from the sale of
advertisements. For 1998 advertising revenue represented 86% of ZDNet's net
revenue. Advertising revenue is generally derived from short-term contracts on
a per impression basis and by the number of product listings in the
ComputerShopper.com site.

  ZDNet believes that its user demographics are attractive to technology and
general consumer product advertisers and merchants. ZDNet has developed
extensive sales and marketing programs designed to assist advertisers in
reaching their audiences through distinctive and customizable programs. ZDNet
sells display advertising in multiple formats, such as banners, sponsorship
wraps, buttons, text and graphical links and e-mail sponsorships, that allow
users to link directly to the advertisers' own Web sites or to special

                                       69
<PAGE>

promotional microsites created by ZDNet on behalf of its advertisers. In
addition, advertising can be purchased in selected areas or across ZDNet's
entire network of sites.

  ZDNet believes that its focused and well-trained sales and marketing
organization is important to attaining and maintaining premium advertising
pricing and maximizing revenue. ZDNet's sales and marketing organization uses
market research tools, such as ZDNet's InternetTrak services, to inform clients
about overall industry trends. InternetTrak is a quarterly marketing survey of
Web users in the U.S. that tracks Web users and their online activities.
ZDNet's direct sales and marketing organization consisted of 86 professionals
as of December 31, 1998. Sales and marketing are generally organized by
geographic region.

  During the fourth quarter of 1998, 377 companies advertised with ZDNet, as
compared to 280 in the fourth quarter of 1997. The following is a list of
ZDNet's top fifteen advertising customers based on advertising revenue in 1998:

Computer Sales Professional          IBM                             3Com/US Robotics
</TABLE>

  No advertiser accounted for more than 5% of ZDNet's revenue during 1998.
ZDNet's 20 largest advertising customers accounted for approximately 46.5% of
net advertising revenue during 1998.

Technology Infrastructure and Operations

  ZDNet has developed an expandable operations infrastructure using open
standard hardware and software systems. ZDNet's network of sites is primarily
hosted on ZDNet servers maintained at multiple locations to facilitate load
balancing and reduce potential downtimes. Additionally, ZDNet outsources
certain hosting and related functions to:

  . NewsCorp/News Internet Services,

  . Real Networks and

  . InterStep, Inc.

  The primary data center is designed to minimize failures by utilizing
redundant equipment and connectivity paths.

  ZDNet has developed systems allowing it to efficiently create new content
channels and build in personalization capabilities. With respect to
advertising, publishing and systems management tools, ZDNet has licensed
technology from:

  . Vignette for its StoryServer publishing system,

  . Thunderstone for its Texis search software and

  . Proxicom for software relating to "threaded messages", which are user
   originated messages that are organized under specific topics and subtopics
   and then are presented to users for further discussion.

                                       70
<PAGE>

  ZDNet also has developed complementary proprietary systems and solutions to
enhance traffic and advertising measurement functions.

Competition

  Competition among Internet content sites is intense and is expected to
increase significantly in the future. The market for Internet content providers
is rapidly evolving and barriers to entry are low, enabling newcomers to launch
competitive sites at relatively low cost.

  ZDNet competes for advertisers, merchants, users and strategic partners with:

  . Web sites specializing in technology information, such as sites provided
   by c|net, CMP, IDG and Internet.com,

  . Internet portals, search sites and content aggregators, such as Excite,
   Infoseek, Lycos and Yahoo!,

  . general purpose online service providers, such as America Online and MSN,

  . general news sites, such as those provided by CNN and ABC,

  . browser/software companies offering information services, such as
   Microsoft and Netscape and

  . large general-interest sites, such as Time Warner's pathfinder.com.

  In addition, ZDNet competes with traditional media content businesses such as
newspapers, magazines, radio and television. Additionally, certain ZDNet
channels compete with Web sites focused on a particular corresponding content
niche. For example, GameSpot competes with Web sites such as those provided by
Imagine Media and HappyPuppy, and the ZDNet Software Library competes with
several software download sites.

  Primary competitive factors in attracting users are:

  . quality,

  . reliability,

  . brand recognition and

  . depth, breadth and presentation of content.

  Primary competitive factors in attracting advertisers are:

  . user demographics and volume,

  . ability to deliver interactive and focused advertising and

  . cost-effectiveness.

  ZDNet's success will depend on its ability to continue to provide
comprehensive, engaging content to attract and maintain both users and
advertisers.

Employees

  As of December 31, 1998, ZDNet had 316 employees, including 149 in Web design
and content development, 86 in sales, marketing, customer support and audience
development, 69 in technical development and operations and 12 in
administration, planning and finance. ZDNet also uses independent contractors
and temporary employees. None of ZDNet's employees is represented by a labor
union. ZDNet considers its relationship with its employees to be satisfactory.

Facilities

  ZDNet's headquarters are located in San Francisco and its other principal
offices are located in the Boston metropolitan area, New York, Chicago, Los
Angeles and Seattle. Ziff-Davis Inc. leases all of the property and offices
occupied by ZDNet and as a result ZDNet pays an allocated portion of Ziff-Davis
Inc.'s lease payments. ZDNet believes that the properties it occupies are
adequate for its current operations, and that suitable additional or
alternative space, including space available under lease options, will be
available on reasonable commercial terms for future expansion.

Legal Proceedings

  Ziff-Davis Inc. was named a defendant in an action, filed on April 17, 1998
in the Supreme Court of the State of New York, by minority stockholders of
SOFTBANK Interactive, formerly an indirect subsidiary of SOFTBANK Corp. The
complaint alleges, among other things, that SOFTBANK Holdings Inc., SOFTBANK
Interactive's majority stockholder, acting with Ziff-Davis Inc. and two of its
senior officers and directors who were directors of SOFTBANK Interactive (and
who were also named as defendants), had conflicts of interest between SOFTBANK
Interactive and other investments of SOFTBANK Corp. and its non-Ziff-Davis Inc.
affiliates (collectively, "Softbank") (including investments in Ziff-Davis
Inc.) and failed to act in the best interests of SOFTBANK Interactive and the
minority stockholders by taking actions which benefited Ziff-Davis Inc. 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.
Ziff-Davis Inc. and the other defendants have moved to dismiss all of the
claims against them other than a breach of contract claim which is solely
against SOFTBANK Holdings, and the motion was granted, with the result that all
of the claims against Ziff-Davis Inc. and its officers were dismissed, and most
of the claims against SOFTBANK Holdings were dismissed, leaving only a claim
against SOFTBANK Holdings concerning the alleged failure of SOFTBANK Holdings
to give plaintiffs adequate notice of the sale of its stock to SOFTBANK
Interactive.

  In addition, eight securities class action suits have been filed against
Ziff-Davis Inc. and certain of its directors and officers in the United States
District Court for the Southern District of New York. The complaints allege
that defendants violated Sections 11, 12(a)(2) and 15 of the Securities Act in
connection with the registration statement filed by Ziff-Davis Inc. with the
Securities and Exchange Commission relating to the initial public offering of
Ziff-Davis Inc.'s common stock. More particularly, the complaints allege that
the registration

                                       72
<PAGE>

statement contained false and misleading statements and failed to disclose
facts that could have indicated an impending decline in Ziff-Davis Inc.'s
revenue. The complaints seek, on behalf of a class of purchasers of Ziff-Davis
Inc.'s common stock from the date of the initial public offering through
October 8, 1998, unspecified damages, interest, fees and costs, rescission, and
injunctive relief such as the imposition of a constructive trust upon the
proceeds of the initial public offering.

  The complaints are as follows: Napoli v. Ziff-Davis Inc., et al., No. 98 Civ.
7158 (filed Oct. 9, 1998); Steinberg, et al. v. Ziff-Davis Inc., et al., No. 98
Civ. 7205 (filed Oct. 13, 1998); Flinker v. Ziff-Davis Inc., et al., No. 98
Civ. 7231 (filed Oct. 14, 1998); Koenig v. Ziff-Davis Inc., et al., No. 98 Civ.
7260 (filed Oct. 15, 1998); Schindler v. Ziff-Davis Inc., et al., No. 98 Civ.
7418 (filed Oct. 19, 1998); Miller v. Ziff-Davis Inc., et al., No. 98 Civ. 7541
(filed Oct. 23, 1998); Felgoise v. Ziff-Davis Inc., et al., No. 98 Civ. 8045
(filed Nov. 9, 1998) and Javier v. Ziff-Davis Inc., et al., No. 98 Civ. 8201
(filed Nov. 17, 1998). On January 28, 1999, the court entered an order
consolidating the actions, appointing lead plaintiff's counsel and requiring
the filing of a consolidated amended complaint within 45 days. The plaintiffs
filed a consolidated complaint on March 15, 1999. The responsive pleading of
Ziff-Davis Inc. and certain of its directors and officers named in the suits is
due April 29, 1999.

  In addition, two derivative suits have been filed by stockholders against
Ziff-Davis Inc. and all of its directors in the Court of Chancery of the State
of Delaware for New Castle County. The complaints allege that the directors
breached their fiduciary duties to Ziff-Davis Inc. by repricing the stock
options awarded to certain directors and demand the nullification of the
repricing and an injunction against exercise by the directors of any repriced
option. The complaints are as follows: Jacobs v. Ziff-Davis Inc., et al., No.
16813NC (filed Nov. 30, 1998) and Bernd Bildstein v. Ziff-Davis Inc., et al.,
No. 16835NC (filed Dec. 10, 1998). Plaintiffs filed an amended complaint on
February 17, 1999, which is substantially similar to the original complaints,
except that the amended complaint also addresses the granting of "new options"
at an allegedly "reduced exercise price". The plaintiffs have also indicated
their intent to seek consolidation of the actions. A response to the amended
complaint is due April 12, 1999.

  Although the outcome of the foregoing cases cannot be predicted, Ziff-Davis
Inc. believes that there are substantial defenses to all of the claims.

  There are no other legal proceedings to which Ziff-Davis Inc. is a party,
other than ordinary routine litigation incidental to its business that is not
otherwise material to the business or financial condition of Ziff-Davis Inc.

             SELECTED HISTORICAL COMBINED FINANCIAL AND OTHER DATA

  The following table presents Selected Historical Combined Financial and Other
Data for ZD as of and for the years ended December 31, 1995, 1996, 1997, and
1998. This data was derived from the Combined Financial Statements of ZD
included elsewhere in this prospectus. An affiliate of Ziff-Davis Inc. acquired
a print publishing business, ZD Publishing, on February 29, 1996; the data does
not include results from the acquired business for periods before the date of
acquisition. However, because ZD Publishing represents ZD's principal
operations, the following table also presents Selected Historical Combined
Financial and Other Data for ZD Publishing as of and for the years ended
December 31, 1994 and 1995 and as of and for the two month period ended
February 28, 1996. The data as of and for the year ended December 31, 1995 and
as of and for the two months ended February 28, 1996 was derived from the
Combined Financial Statements of ZD Publishing. ZD Publishing data as of for
the year ended December 31, 1994, was derived from ZD Publishing unaudited
financial statements. On May 4, 1998, Ziff-Davis Inc. completed a
reorganization described in Note 2 to the Combined Financial Statements of ZD;
results for periods before the reorganization are not directly comparable to
results for periods after the reorganization. This table should be read in

Management's Discussion and Analysis of Financial Condition and Results of
Operations for each of ZDNet, ZD and Ziff-Davis Inc. and Financial Statements

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

Revenue

  ZD had net revenue of $1.053 billion for 1998. A substantial portion of ZD's
revenue is derived from the sale of advertising, which in 1998 accounted for
49.8% of total revenue. No single advertiser has comprised more than 4.0% of
ZD's advertising revenue during any of the last three years. However, ZD's top
20 advertisers accounted for 37.5% of total advertising revenue for 1998.

  In the publishing segment, ZD's principal sources of revenue are advertising
(64.4% of 1998 total publishing revenue), circulation (18.7%) and other (16.9%)
for the year ended December 31, 1998. Circulation comprises both paid
subscriptions (10.9%) and newsstand sales (7.8%) while other includes
educational and training materials (7.4%) and market research studies (7.1%)
with the balance primarily consisting of royalties, reprints and other
miscellaneous sales. In the events segment, revenue is derived from two
principal sources: sale of exhibit space (66.8% of 1998 total segment revenue)
and attendee conference and seminar fees (14.1%). Unlike many trade show
producers, ZD derives a significant portion of its trade show revenue from
other sources (19.1%), including advertising in show-related publications,
billboards, banners, fees from managing customer-sponsored events and other
show-related activities. ZD believes these other sources will continue to be an
important growth area, particularly for its content-focused events.

  ZD provides certain editorial content and brands for ZDNet for which ZDNet
pays a royalty to ZD based on ZDNet's revenue. See Note 5 to ZD's Combined
Financial Statements in this prospectus.

Cost of Operations

  In the publishing business, the principal components of ZD's production costs
are raw materials, printing and distribution, which represented 34.5%, 38.0%
and 27.2%, respectively, of total 1998 publishing production expenses. ZD'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--Other Ziff-Davis Inc. Risks--Ziff-
Davis Inc. May Be Adversely Affected By Fluctuations In Paper And Postage
Costs" and "--Inflation and Fluctuations in Paper and Postage Costs". The
principal components of production costs within the events business are the
costs of renting and preparing the facilities to hold the events (46.8% in
1998), direct mail and the related costs for promotion of the events (37.0% in
1998) and program development and presentation costs (13.4% in 1998).

  The other principal operating costs for ZD are selling, general and
administrative expenses, including editorial costs. Included in these costs are
salaries, sales commissions and benefits (56.6% in 1998) along with marketing
and promotion expenses related to advertising and circulation (20.2% in 1998).

  Ziff-Davis Inc. provides certain selling, general and administrative services
and shared services on a centralized basis and the costs of these central
services are allocated between ZD and ZDNet. See Note 5 to ZD's Combined
Financial Statements in this prospectus.

Factors affecting future periods

  ZD'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 expenditures by ZD'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, ZD may experience fluctuations in revenue from period to period.
Many of ZD'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 pressures and temporary surpluses of inventory. Revenue and
profitability are also influenced by product mix and the timing and frequency
of ZD'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, ZD's revenue from year to year may be
affected by the number and timing of new product launches. If ZD concludes that
a new publication, trade show or service will not achieve certain milestones
with regard to revenue, 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--Other Ziff-Davis Inc. Risks--To Remain Competitive Ziff-Davis Inc.
Must Constantly Expand And Develop New Products And Services. This Is
Inherently Risky And Expensive".

  On February 4, 1999, ZD purchased ZDTV. This purchase will affect ZD's
results in future periods. See "--ZDTV" below for certain summary pro forma and
other information about this purchase.

  ZD expects to recognize compensation expense of approximately $7.9 million as
a result of certain options granted on December 21, 1998 and January 29, 1999.
Such compensation expense will be recognized over the vesting period of the
options. The 1999 compensation expense related to these options is expected to
be approximately $2.2 million. See Note 15 to ZD's Combined Financial
Statements in this prospectus.

Presentation of Financial Information

  ZD is comprised of certain operations which were acquired at various times
and completed a reorganization in May 1998. See Notes 1 and 2 to ZD's Combined
Financial Statements in this prospectus.

  In order to create financial statements that separately present ZD's assets,
liabilities, revenue, expenses and cash flow while still reflecting ZD's 100%
retained interest in

                                       78
<PAGE>

ZDNet's division equity and net losses, ZD has accounted for its interest in
ZDNet in a manner similar to the manner prescribed by APB No. 18, The Equity
Method of Accounting for Investments in Common Stock. Thus, ZD's historical
balance sheets reflect ZD's 100% retained interest in ZDNet's division equity
as "Retained interest in ZDNet". Similarly, ZD's historical statements of
operations reflect ZD's 100% retained interest in ZDNet's division losses as
"Loss related to retained interest in ZDNet".

  Since ZD and ZDNet together constitute all of Ziff-Davis Inc. and since ZD's
financial statements have historically reflected 100% of ZDNet's division
equity and losses, ZD's division equity and net income or loss has historically
been equal to Ziff-Davis Inc.'s total stockholders' equity and net income or
loss.

  However, ZD's 100% retained interest will decline in the future to reflect,
among other things, the ZDNet stock sold in the offering. When ZD's retained
interest declines to a percentage below 100%, ZD's net income or loss will,
going forward, reflect only that reduced percentage of ZDNet's division income
or loss.

  The book value associated with ZD's retained interest will increase or
decrease, among other things, to reflect ZD's proportionate retained interest
in ZDNet's division income or loss and will be adjusted from time to time as
set forth under Note 3 to ZD's Combined Financial Statements in this
prospectus.

Results of Operations

  The table below presents the results of ZD as if the assets and operations
acquired by affiliates of Ziff-Davis Inc. on February 29, 1996 (as described in
Note 1 to the Combined Financial Statements in this prospectus) had been
acquired on January 1, 1995. Purchase accounting adjustments relating to that
acquisition have been reflected through pro forma amortization, interest and
income tax adjustments, as described in note (1) to the table. Although the
1996 presentation is not in accordance with generally accepted accounting
principles, management believes it presents the most meaningful basis of
comparison. The financial information presented below may not necessarily
reflect the results of operations which would have occurred had the February
29, 1996 acquisition been completed on January 1, 1995.

(1) The February 29, 1996 acquisition gave rise to different bases of
    accounting for the period after the acquisition as compared to 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 above numbers assume that the acquisition took place on
    January 1, 1995; therefore, depreciation and amortization, interest expense
    and net loss have been increased by approximately $6,064,000, $824,000 and
    $10,383,000 for 1996.

                                       80

(2) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. ZD's EBITDA is calculated by adding
    (a) ZD's EBITDA before losses related to its retained interest in ZDNet and
    (b) ZD's proportionate interest (currently 100%) in ZDNet's EBITDA. EBITDA
    for the year ended December 31, 1998 is before a one-time restructuring
    charge of $52,239,000. 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 ZD's operating performance or to cash flows as a measure of
    liquidity. Although ZD 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, the EBITDA presented for ZD
    may not be comparable to similarly titled measures reported by other
    companies.

Year ended December 31, 1998 compared with year ended December 31, 1997

 Revenue, net

  Revenue decreased by $68.8 million or 6.1% from $1,121.5 million in 1997 to
$1,052.7 million in 1998.

  Publishing--Revenue from publishing decreased by $51.1 million or 6.1% from
$834.0 million in 1997 to $782.9 million in 1998. This decline was primarily
due to the transfer of certain publications to a joint venture and the closure
of three publications due to the restructuring discussed below. The remainder
of the decrease was primarily due to lower advertising in business publications
partly offset by growth in advertising in consumer publications. Advertising
revenue was lower in business publications principally due to factors affecting
the computer technology industry during the year. Margin pressure on computer
equipment manufacturers, industry and product delays, lower demand in Asia and
a focus on the Year 2000 transition are contributing to a reduced demand for
advertising in Ziff-Davis Inc.'s magazines. Revenue from international
operations, which generated 10.2% of the segment's revenue, increased by $2.1
million due to the launch of IT Week in the UK, partially offset by lower
advertising in business publications.

  Net revenue from MacUser and MacWeek magazines contributed to Mac Publishing
LLC were $32.5 million for 1997 but are no longer consolidated into Ziff-Davis
Inc.'s results for 1998. On May 1, 1998, Ziff-Davis Inc. acquired its joint
venture partner's 50% interest in FamilyPC magazine. Ziff-Davis Inc. now owns
100% of the magazine and its results are included in the consolidated results
from the acquisition date. Revenue from FamilyPC included in the 1998 results
was $11.1 million. Revenue related to the three publications closed as part of
the restructuring was $12.5 million lower in the fourth quarter of 1998 as
compared to the fourth quarter of 1997.

  Events--Revenue from events decreased by $17.7 million or 6.1% from $287.5
million in 1997 to $269.9 million in 1998. The decrease was primarily due to a
decline in revenue due to the discontinuation of certain "one-time" shows that
were held in 1997, lower ancillary revenue at COMDEX/Fall and lower square
footage sold at COMDEX/Spring. This decrease was partially offset by increased
revenue from increased square footage sold at Networld+Interop Las Vegas and
Java One due to an increased number of attendees.

                                       81
<PAGE>

 Cost of production

  Production costs decreased by 7.3% or $23.5 million from $320.9 million in
1997 to $297.4 million in 1998.

  Publishing production costs decreased by $6.1 million or 2.7% from $221.4
million in 1997 to $215.3 million in 1998. The decrease was related to a
decline in the number of advertising pages produced.

  The cost of producing events decreased by $17.4 million or 17.4% from $99.5
million in 1997 to $82.1 million in 1998. The decrease is a result of lower
operational costs and re-negotiated contracts as well as the discontinuance of
certain "one-time" shows that were held in 1997.

 Selling, general and administrative expenses

  Selling, general and administrative expenses decreased by $3.4 million or
0.7% from $521.7 million in 1997 to $518.3 million in 1998. The decrease was
due primarily to the headcount reduction and efficiencies attained through the
integration of operations resulting from the reorganization completed in May
1998, as well as costs eliminated by the closure of three magazines in the
fourth quarter of 1998. This decrease was partially offset by increased costs
relating to the launch of new products and services and increased advertising
expenses.

 Depreciation and amortization

  Total depreciation and amortization decreased $1.2 million from $147.3
million in 1997 to $146.1 million in 1998. The decrease was a result of certain
assets being fully depreciated in 1997 and early 1998.

 Restructuring

  Margin pressure on computer equipment manufacturers, industry and product
delays, lower demand in Asia and a focus on the Year 2000 transition are
contributing to a reduced demand for advertising in ZD's magazines, principally
PC Magazine, PC/Computing, Computer Shopper and PC Week. ZD believes these
factors are continuing.

  As a result of this reduced demand, in October 1998, Ziff-Davis Inc.
announced a restructuring program with the intent of significantly reducing its
cost base. Ziff-Davis Inc. incurred a pre-tax charge of $52.2 million for this
restructuring program. The charge was reported as a component of income from
operations for the fourth quarter of 1998. The charge included asset impairment
costs ($37.9 million), employee termination costs ($8.6 million), and costs to
exit activities ($5.7 million) principally resulting from the closing of three
publications, Windows Pro, Internet Business and Equip, and the reduction of
Ziff-Davis Inc.'s work force by 310 employees. The charge also included costs
resulting from the discontinuation of certain educational journals and trade
shows. The following sets forth additional detail concerning the principal
components of the charge:


                                       82
<PAGE>

  .  Asset impairment costs totaled $37.9 million. These costs included the
     write-off of intangible assets associated with the discontinued
     publications ($34.3 million) and trade shows ($2.9 million) as well as
     deferred expenses associated with the discontinued educational journals
     ($0.7 million).

  .  Employee termination costs related to severed personnel at the closed
     publications as well as a rationalization and resulting workforce
     reduction of the remainder of
     Ziff-Davis Inc.'s operations. Employee termination costs included
     payments for severance and earned vacation as well as the costs of
     outplacement services and the provision of continued benefits to
     personnel. As of December 31, 1998, $5.2 million of the $8.6 million
     related to these employee terminations had been paid.

  .  Costs to exit activities reflect the costs associated with the final
     closure of the discontinued publications ($1.8 million) and the costs to
     reduce office space under lease as a result of the reduced level of
     employees ($3.8 million).

 Interest expense, net

  Interest expense decreased by $46.9 million or 24.6% from $190.4 million in
1997 to $143.5 million in 1998. The reduction was due primarily to lower levels
of debt outstanding throughout the year, as well as the capitalization of
$908.7 million of intercompany debt as part of the reorganization.

 Loss related to retained interest in ZDNet

  The loss related to the retained interest in ZDNet decreased by $13.4 million
from $21.2 million in 1997 to $7.9 million in 1998. This decrease is due to
improved performance of that business. See "ZDNet Management's Discussion and
Analysis of Financial Condition and Results of Operations" elsewhere in this
prospectus.

 Other non-operating income, net

  Other non-operating income, net primarily reflects ZD's equity share in
earnings and losses from joint ventures and fees earned from management of
events not produced by ZD. This income decreased $0.2 million or 2.4% from $8.3
million in 1997 to $8.1 million in 1998 reflecting reduced fees from managed
events. The decline was partially offset by ZD's equity share in earnings of
MAC Publishing, LLC, an entity that was formed in August 1997.

 Income taxes

  The 1998 income tax benefit of $26.9 million increased from $0.5 million
reported in 1997. The increase was due primarily to income tax benefits
generated from the losses with respect to the MAC Assets, which were not
deductible until ZD purchased the MAC Assets from an affiliate on May 4, 1998.
The income tax benefit was also increased by a higher net loss for the year
ended December 31, 1998 compared to the net loss for the year ended December
31, 1997.


                                       83
<PAGE>

 Net loss

  As a result of the changes described above, the net loss for the period
increased $6.6 million or 9.3% from $71.2 million in 1997 to $77.8 million in
1998.

 EBITDA

  EBITDA for the year ended December 31, 1998 was $244.1 million compared to
$272.9 million for the year ended December 31, 1997. EBITDA for the year ended
December 31, 1998 does not include the $52.2 million restructuring charge.
Results were unfavorable as compared to last year due to a lower level of
earnings from advertising in the higher margin business publications partly
offset by improved results in the events segment and reduced losses from ZD's
retained interest in ZDNet. The improvement in the events segment was
attributed to the absence of losses from the discontinuance of certain "one-
time" shows held in 1997 as well as continued costs savings. Reduced losses
from ZDNet were the result of revenue growth exceeding increases in expenses.
The ratio of EBITDA to revenue was 23.2% for 1998 compared to 24.3% in 1997.

Year ended December 31, 1997 compared with Pro Forma Year ended December 31,
1996

 Revenue, net

  Net revenue increased by $60.0 million or 5.7% from $1,061.5 million in 1996
to $1,121.5 million in 1997.

  Publishing--Net revenue from publishing grew by $37.4 million or 4.7% from
$796.6 million to $834.0 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. Increases in
advertising rates, generally ranging between 3.0% and 10.0%, and a 5.1%
increase in advertising pages contributed $11.5 million. Revenue from
international operations, which generated 9.5% of the segment's revenue,
decreased by $1.5 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.

  Events--Net revenue from events 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 $21.2 million or 7.1% from $299.7 million to
$320.9 million.

  Publishing production costs increased $9.1 million or 4.3% from $212.3
million in 1996 to $221.4 million in 1997. Costs related to new launches and
volume-related growth

                                       84
<PAGE>

increased approximately $20 million but were partly offset by approximately $10
million of lower paper costs.

  The costs of producing events increased $12.2 million or 14.0% from $87.3
million in 1996 to $99.5 million in 1997 primarily as a result of costs related
to new events launched in 1997.

 Selling, general and administrative expenses

  Selling, general and administrative expenses increased $21.8 million or 4.4%
from $499.9 million to $521.7 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 events business which was announced in
the fourth quarter of 1997. Costs for the publishing segment rose 1.2% while
those for the events 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 $7.6 million to $147.3 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.

 Loss related to Retained Interest in ZDNet

  The loss from ZD's retained interest in ZDNet increased to $21.2 million in
1997 from $17.9 million in 1996 due to the operating performance of that
business. See "ZDNet Management's Discussion and Analysis of Financial
Condition and Results of Operations".

 Other non-operating income, net

  Other non-operating income, net primarily reflects ZD's equity share in
earnings and losses from joint ventures and fees earned from management of
events not produced by ZD. This income increased $2.2 million from $6.1 million
in 1996 to $8.3 million or 36.1% primarily due to a $2.2 million or 36.3%
increase in ZD's share of Mac Publishing, LLC's earnings.

 Income Taxes

  The 1997 combined income tax benefit of $0.5 million compares to a pro forma
income tax provision of $26.8 million in 1996. The improvement in the tax
provision is due to a

                                       85
<PAGE>

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
($42.0 million in 1997 and $63.0 million in 1996), non-deductible goodwill
amortization ($10.2 million in 1997 and $8.6 million in 1996) and state and
local income taxes. In addition, the 1996 tax provision increased approximately
$2.1 million as a result of pro forma adjustments related to the ZDI
acquisition.

 Net loss

  As a result of the changes 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 6.9% 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 24.3% for 1997 compared to the 1996 margin of 24.1%.

Liquidity and Capital Resources

 Sources and uses of cash

  As a result of the May 4, 1998 reorganization, ZD's intercompany debt owed to
Softbank was reduced to $83.1 million. Such indebtedness bears interest at 9.9%
and matures in February 2010. Concurrently with Ziff-Davis Inc.'s initial
public offering, Ziff-Davis Inc., on behalf of ZD, issued and sold $250 million
aggregate principal amount of notes. In addition, Ziff-Davis Inc., on behalf of
ZD, entered into a $1.35 billion credit facility, and borrowed $1.25 billion
under such facility, to provide additional funds for the repayment of
intercompany debt to Softbank and to provide for ZD's working capital
requirements. The balance of intercompany obligations owed to Softbank was
converted to equity. See Note 2 to the Combined Financial Statements in this
prospectus.

  At December 31, 1998, ZD's outstanding total debt was $1,547.9 million,
excluding unamortized discount, which consisted of $77.9 million due to
Softbank, $250 million in notes and $1,220.0 million under the credit facility.
Under its most restrictive covenant, ZD could have borrowed an additional
$28,800,000 under the credit facility at December 31,1998. For information
concerning the terms of this debt, see "Ziff-Davis Inc.'s Debt".

  Cash and cash equivalents were $32.3 million at December 31, 1998, an
increase of $2.0 million from $30.3 million at December 31, 1997. The increase
was due to the factors discussed below:


                                       86
<PAGE>

  Cash provided by operations was $100.3 million for the year ended December
31, 1998 compared to $11.9 million for the year ended December 31, 1997. The
increase from 1997 to 1998 was attributed to ZD's lower losses before the
restructuring charge, lower working capital and a decrease in funding to
affiliates and to ZDNet for the 1998 period.

  Cash used in investing activities for the year ended December 31, 1998
totaled $69.2 million compared to $59.5 million for the year ended December 31,
1997. The majority of these expenditures were for computer equipment and
leasehold improvements as well as for funding the operation of ZDNet.
Acquisitions and investments in the 1998 period relate to ZD's acquisition of
Sky TV, a trade show in Canada, an additional 50% interest in Family PC
magazine, a European marketing database company as well as an investment in Red
Herring. Acquisitions for the 1997 period reflected the purchase of a 70%
interest in GameSpot.

  Cash used in financing activities totaled $29.1 million for the year ended
December 31, 1998, representing proceeds from the reorganization and initial
public offering of $1,863.3 million, net of transaction costs, and funding from
Softbank of $20.4 million offset by the repayment of debt and amounts due to
affiliates of $1,916.1 million. Cash provided by financing activities in 1997
amounted to $47.9 million representing capital contributions partly offset by
repayments of intercompany debt.

  ZD had a working capital surplus of approximately $22.6 million at December
31, 1998, compared to a working capital deficit of approximately $379.8 million
at December 31, 1997. Ziff-Davis Inc.'s balance sheet has historically had a
working capital deficit due to significant amounts due to affiliates. ZD also
maintains a significant level of deferred revenue generated from publication
subscriptions paid in advance and prepayments from trade show exhibitors. At
December 31, 1998, Ziff-Davis Inc. had deferred revenue of $151.0 million
compared to $154.7 million at December 31, 1997. Deferred revenue does not
represent a cash liability owed by Ziff-Davis Inc., unless Ziff-Davis Inc.
fails to deliver a magazine or cancels a trade show, and generally does not
affect Ziff-Davis Inc.'s ability to fund day-to-day operations. Working capital
increased as a result of the reorganization and the initial public offering of
Ziff-Davis Inc.'s common stock which resulted in the repayment and conversion
to equity of related party obligations in connection therewith.

  On December 11, 1998, Standard & Poors lowered its corporate credit and bank
loan ratings for Ziff-Davis Inc. to BB- from BB and its subordinated debt
rating for Ziff-Davis Inc. to B from B+. This downgrade had no impact on our
current borrowings. Although this downgrade may make future borrowings more
expensive, we do not believe this will have a material impact on our liquidity
or our access to credit markets.

  ZD believes, based on its current level of operations and anticipated growth,
that ZD's ability to generate cash, together with cash on hand and available
lines of credit, will be sufficient to make required payments of principal and
interest on ZD's indebtedness and fund anticipated capital expenditures and
working capital requirements. However, actual capital requirements may change,
particularly as a result of any acquisitions ZD may

                                       87
<PAGE>

pursue. The ability of ZD to meet its debt service obligations and reduce its
total debt will depend upon the future performance of ZD.

 Funding for ZDNet

  In the financial statements of ZD and ZDNet, whenever ZDNet had a cash need,
other than cash needs of ZDNet's foreign operations or cash needs of ZDNet's
operations that are not wholly owned, that cash need was funded by ZD and
accounted for as a capital contribution (i.e., as an increase in ZDNet's
division equity and ZD's Retained Interest in ZDNet). Accordingly, no interest
income from ZDNet has been reflected in the financial statements of ZD. After
the date on which ZDNet stock is first issued, Ziff-Davis Inc. will account for
all cash transfers from one group to or for the account of the other group,
other than transfers in return for assets or services rendered or transfers in
respect of ZD's retained interest that correspond to dividends paid on ZDNet
stock, as inter-group revolving credit advances. These advances will bear
interest at the rate at which Ziff-Davis Inc. could borrow such funds on a
revolving credit basis as the board of directors determines in its sole
discretion. However the board of directors has the discretion to determine that
a given transfer or type of transfer should be accounted for as a long-term
loan, a capital contribution increasing ZD's retained interest in ZDNet or a
return of capital reducing ZD's retained interest in ZDNet.

Credit Facility

  ZD's credit facility, as amended, consists of a seven-year $400 million
reducing revolving credit facility, a seven-year $450 million term loan and an
eight-year $500 million term loan. There are no scheduled reductions in the
revolving credit commitment or amortization under the term loan until September
2000.

  For the reasons described under "--Restructuring" above, Ziff-Davis Inc.'s
debt to EBITDA ratios at December 31, 1998 would have been above the levels
that originally had been required by its credit facility. On December 16, 1998,
the lenders of the $1.35 billion credit facility agreed to amend certain
provisions of that facility. The amended provisions include an increase in the
allowed leverage ratios. In return, ZD agreed to pay a one-time fee of $3.375
million and increase rates on amounts borrowed under the facility to rates
currently ranging from LIBOR plus 2.875% to LIBOR plus 3.375% depending on the
type of loan. Had the increased interest rates been in effect for the period
from Ziff-Davis Inc.'s initial public offering on April 28, 1998 to December
31, 1998, interest expense would have increased by approximately $11.9 million.
Based on the $1,220.0 million outstanding on December 31, 1998, the annualized
incremental interest is $18.0 million. This increase in interest expense would
reduce the amount otherwise available for funding ZD or ZDNet operations.

  ZD's credit facility exposes it to market risk with respect to changes in
interest rates. ZD manages this risk through the use of interest rate swap
agreements, as described below. Through the use of these swap agreements, ZD
has effectively established a fixed interest rate for $550 million of the
outstanding credit facility. Based on the $1,220.0 million

                                       88
<PAGE>

outstanding under the credit facility at December 31, 1998, if the LIBOR rate
were to increase by 1%, ZD would incur, after giving effect to the swap
agreements, an additional $6.7 million of annual interest expense.

  For a description of the terms of the amended credit facility, see "Ziff-
Davis Inc.'s Debt".

Interest Rate Swaps

  On June 10, 1998, ZD entered into interest rate swap agreements, with an
aggregate notional amount of $550 million. Under these swap agreements, which
commenced on August 10, 1998, ZD receives a floating rate of interest based on
three-month LIBOR, which resets quarterly, and pays a fixed rate of interest
each quarter for the terms of the respective agreements. The weighted average
fixed rate ZD pays under these agreements is 5.85%. ZD has entered into these
agreements solely to hedge its interest rate risk. At December 31, 1998, the
three-month LIBOR rate was 5.06%.

  These swap agreements are viewed by ZD as risk management tools and are not
used for trading or speculative purposes. The notional amount of $550 million
does not represent a real amount exchanged by the parties, and therefore, is
not a measure of ZD's exposure through its use of swap agreements. The fair
values of these swap agreements were estimated by obtaining quotes from brokers
which represented the amounts that ZD would pay if the agreements were
terminated at the balance sheet date. While it is not ZD's intention to
terminate these swap agreements, these fair values indicated that the
termination of these swap agreements would have resulted in a loss of
$15,627,000.

  By nature, swap agreements involve credit risk, due to the possible
nonperformance by counterparties. To mitigate this risk, ZD enters into swap
agreements with major financial institutions and diversifies the counterparties
used as a means to limit counterparty exposure and concentration of risk.

ZDTV

  In July 1997, Ziff-Davis Inc. entered into a license and services agreement
to develop ZDTV for MAC Holdings (America) Inc., a company that is wholly owned
by Mr. Masayoshi Son, who is a director of Ziff-Davis Inc. and principal
stockholder of SOFTBANK Corp. Under this agreement, Ziff-Davis Inc. agreed to
fund ZDTV's operations through unsecured advances and was granted an option to
purchase ZDTV for a price equal to MAC Holdings' investment plus 10% per annum
for the period of investment. On January 15, 1999, Ziff-Davis Inc. exercised
this option and on February 4, 1999 purchased ZDTV at a purchase price of $81.4
million. Ziff-Davis Inc. paid approximately $32.8 million of the purchase price
in cash, funded on February 5, 1999, and paid the remainder by applying
approximately $48.6 million in advances owed to it by MAC Holdings through
December 31, 1998. Ziff-Davis Inc. also agreed to be responsible for the
funding of ZDTV during the period in 1999 prior to the purchase, which will be
accounted for as additional purchase price. The cash portion of the purchase
price was funded by an advance from ZDTV to Ziff-Davis Inc.,

                                       89
<PAGE>

pursuant to the ZDTV cash management system, of the funds invested in ZDTV by
Vulcan Programming described below. In connection with its acquisition of ZDTV,
Ziff-Davis Inc. assumed MAC Holdings' obligations under an option granted to
DirectTV to purchase 5% of ZDTV for $15 million, subject to adjustment.

  Ziff-Davis Inc. currently has certain long-term agreements to distribute ZDTV
via satellite. Historically, start-up cable television channels have required
substantial investment and there can be no assurance that ZDTV will ultimately
obtain sufficient cable carriage and commercial acceptance to be profitable.
The following unaudited pro forma information assumes that the acquisition of
ZDTV and the sale of a one-third interest in ZDTV to Vulcan Programming had
been consummated on January 1, 1998. Adjustments for ZDTV transactions include
the operating results of ZDTV, amortization of the purchase price of ZDTV,
Vulcan Programming's one-third interest in the losses of ZDTV and the tax
effect of these items. The pro forma data is not necessarily indicative of
actual results had the transaction occurred at January 1, 1998. Further, pro
forma results are not intended to be indicative of future financial results.

  ZDTV's cash requirements are currently expected to be approximately $50
million for 1999. The $54 million invested in ZDTV by Vulcan Programming will
be used to fund ZDTV and thereafter cash requirements will be funded by the
partners or by third parties.

  Ziff-Davis Inc. intends to file appropriate financial statements and pro
forma information regarding ZDTV on or before April 20, 1999 as set forth in
its Form 8-K filed with the SEC on February 19, 1999.

Vulcan Transactions

  On February 5, 1999, Vulcan Programming, Inc., an entity owned by Paul G.
Allen, purchased a one-third interest in ZDTV for $54 million. On March 4,
1999, Vulcan Ventures, the investment vehicle of Paul G. Allen, purchased
approximately three million shares of Ziff-Davis Inc. common stock for $50
million.

Seasonality

  Historically, ZD's business has been seasonal as a significant portion of
annual revenue has occurred 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, 1998. In
the opinion of the Ziff-Davis Inc.'s management, this unaudited information has
been prepared on a basis consistent with the audited Combined Financial
Statements of ZD appearing elsewhere in this prospectus 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.

(1) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. ZD's EBITDA is calculated by adding
    (a) ZD's EBITDA before losses related to its retained interest in ZDNet and
    (b) ZD's proportionate interest (currently 100%) in ZDNet's EBITDA. EBITDA
    for the quarter ended December 31, 1998 does not include one-time
    restructuring charge of $52,239,000. 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 ZD's operating performance or to cash
    flows as a measure of liquidity. Although ZD 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, the
    EBITDA presented for ZD may not be comparable to similarly titled measures
    reported by other companies.

Inflation and Fluctuations in Paper and Postage Costs

  ZD continually assesses the impact of inflation and changes in paper prices.
ZD generally enters into contracts for the purchase of paper which adjust the
price on a

                                       91
<PAGE>

quarterly basis. Paper prices began to rise in 1994, rose significantly in 1995
and 1996 and then decreased in 1997. During 1998, paper prices were relatively
flat. Management anticipates that paper prices will remain relatively stable in
1999. ZD will continue to monitor the impact of inflation and paper prices and
will consider these matters in setting its pricing policies. ZD 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, ZD has not entered, and does not currently plan to enter,
into long-term forward price or option contracts for paper. Management
estimates postage costs will increase approximately 3.5% in 1999. See "Risk
Factors--Other Ziff-Davis Inc. Risks--Ziff-Davis Inc. May Be Adversely Affected
By Fluctuations In Paper And Postage Costs" and "ZD Description of Business--
Print Publishing".

Year 2000 Readiness Disclosure

  During 1997, Ziff-Davis Inc., including the businesses comprising ZD, began a
review of its computer systems and software to identify systems and software
which might malfunction due to misidentification of the Year 2000. Ziff-Davis
Inc. is using both internal and external resources to identify, test, correct
and reprogram systems and software for Year 2000 readiness.

  At December 31, 1998, Ziff-Davis Inc. was in the research and validation
phase of its Year 2000 project for information technology or IT systems and
non-IT systems. This phase consists of research and validation of all
infrastructure, hardware and software, including platform, wide-area network
and local-area network components. Research for non-IT systems includes
identifying systems that include embedded technology, such as micro-
controllers, which are not Year 2000 compliant.

  Ziff-Davis Inc. has identified critical systems and applications that will
either be validated for compliance though formal documentation, through vendors
or through testing. Ziff-Davis Inc. will enter the testing phase of its
infrastructure, hardware, software and databases in the first quarter of 1999
and plans to complete such phase by September 1, 1999. Contingency plans will
be developed for any systems or platforms that are known to be non-compliant as
of September 1, 1999.

  Some of Ziff-Davis Inc.'s computer systems and databases, including its
subscription fulfillment and payroll systems, are managed by third parties
under contractual arrangements. Ziff-Davis Inc. currently has no Year 2000
compliance problems known to it relating to third parties. Ziff-Davis Inc. has
requested those third parties with which Ziff-Davis Inc. has material
relationships in the first quarter of 1999 to advise it as to whether such
third parties anticipate difficulties in addressing Year 2000 compliance
problems, and if so, the nature of such difficulties. Ziff-Davis Inc.
anticipates that such inquiries will be completed by April 30, 1999.

  In addition, Ziff-Davis Inc. will develop contingency plans during the second
half of 1999 in order to compensate for any disruption or downtime that could
result from a Year

2000 compliance problem. Ziff-Davis Inc. plans to replace IT and non-IT systems
that it determines are not Year 2000 compliant prior to October 1, 1999 in
order to minimize any risk of a Year 2000 compliance problem.

  Ziff-Davis Inc. has incurred remediation costs associated with its Year 2000
readiness efforts. These remediation costs have been incurred in connection
with replacement of systems and hardware, modification of software and
consulting costs related to Year 2000 solution providers. The costs to address
Year 2000 issues which have been included in the general and administrative
expenses of Ziff-Davis Inc. have not been tracked separately and are therefore
not determinable. However, management believes these expenses have been
substitutive rather than incremental to the recurring level of general and
administrative expenses. Total capitalized costs incurred in the replacement of
systems in connection with Ziff-Davis Inc.'s Year 2000 readiness efforts as of
December 31, 1997 and 1998 were $1,692,000 and $3,837,000, respectively. Ziff-
Davis Inc. estimates that it will capitalize an additional $3,815,000 during
1999 related to its Year 2000 readiness efforts.

  Ziff-Davis Inc. expects to complete testing and replacement of critical
systems by the beginning of the fourth quarter of 1999. Ziff-Davis Inc.'s
estimate of ZD's most reasonably likely "worst case scenario" would be the
failure of its internal applications and systems that process and store certain
information and data. Ziff-Davis Inc. would resolve the failure of such
applications and systems one by one and management of Ziff-Davis Inc. does not
believe that the impact on its critical systems would be material. However, if
Ziff-Davis Inc. or any subscribers, advertisers, licensors, vendors or other
third parties on whom it relies experiences a Year 2000 compliance problem,
this could have a material adverse effect on ZD's profit and liquidity.

Recently Issued Accounting Pronouncements

  SFAS No. 133 Accounting for Derivative Instruments and Hedging Activities
issued in June 1998, establishes accounting and reporting standards for
derivative instruments and for hedging activities and is effective for all
fiscal quarters of fiscal years beginning after June 15, 1999. Ziff-Davis Inc.
does not expect the adoption of SFAS No. 133 to have a material impact on ZD's
results of operations.

  ZD expects to adopt this statement beginning with its 2000 financial
statements.

                            DESCRIPTION OF BUSINESS

  Ziff-Davis Inc. is a leading media and marketing company that provides
information on computing and technology, including the Internet. ZD is the
division of Ziff-Davis Inc. focused on the businesses of print publishing,
trade shows and conferences, market research, education, including ZDU, our
Internet-based educational service, and television, including an online
component. ZD provides technology companies worldwide with marketing strategies
for reaching key decision-makers.

  ZD's PC Magazine, PC Week and Computer Shopper magazines were 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 1997. In 1998, ZD was the largest technology
publisher in the U.S. in terms of magazine revenue with at least 50% more
magazine revenue than its closest competitor. In 1997, ZD accounted for 36.8%
of all advertising and circulation dollars spent in computer periodicals. ZD
believes its publications provide readers and advertisers with comprehensive
market and product coverage and quality editorial content.

  Through ZD Events, ZD also produces some of the world's most important trade
shows serving vendors, resellers, buyers and users of computer technology and
the Internet. In 1998, ZD produced over 50 trade shows and conferences
worldwide with over two million estimated attendees. ZD'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.

  ZD's other media and marketing platforms include market research, education
and publication of computer-related newsletters and training manuals and
television. ZD also currently has a 100% retained interest in ZDNet, Ziff-Davis
Inc.'s online business division, although that interest will decline to reflect
the initial issuance of ZDNet stock as well as any future issuances.

Industry Background

  Technology continues to be one of the largest and fastest growing sectors of
the U.S. economy. The market for technology goods and services is rapidly
expanding due to increased integration of computers into the workplace and
home, shortened product life cycles and increased use of the Internet. The
demand for computer technology to enhance productivity and the increasing
number of applications in the areas of education, entertainment and
communications has dramatically increased the number of computers in use
worldwide, from 150 million in 1993 to over 300 million in 1997. This increase
in computer usage has significantly broadened the consumer and business markets
for computer technology. In addition, rapid technological advances have
shortened product life cycles. Today, the estimated marketable product life of
a PC is less than six months as compared to five years in 1981. The Internet
has also become a widely accepted information tool. Forrester Research Inc.
estimates that the number of adult Web users will reach 51 million in the U.S.
by the end of 1998 and will grow to 99 million by the end of 2001.

                                       94
<PAGE>

  These factors have led to increased demand among buyers and users of computer
technology product for objective, up-to-date information and analysis. To meet
this demand, sellers of computer technology products need to effectively
advertise to increase sales, educate consumers, improve end-user satisfaction
and build brand loyalty. Computer technology-focused media enables sellers to
communicate their message effectively by targeting a focused customer base. As
a result of a broadening consumer base containing favorable demographics,
computer technology publications and other media are becoming increasingly
attractive as a platform for consumer product advertising.

 Computer Technology Print Publications Market

  Advertising and circulation revenue for computer-oriented print publications
grew on average 10% a year from 1994 to 1997, totaling $1.7 billion in 1997.
However, in 1998 computer advertising pages decreased 8% as compared to 1997,
according to Adscope and CMR. Ziff-Davis Inc. believes the decline in the
technology advertising market is due mainly to continuing margin pressure on
computer equipment manufacturers, industry and product delays, lower demand in
Asia and a focus on the Year 2000 transition.

 Computer Technology Trade Shows

  Trade show attendees 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 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 and Cisco Systems, Inc. use 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 an increasingly important marketing strategy for information
technology vendors and can be an effective medium for generating and closing
sales. In 1998 estimated exhibit space revenue from North American computer-
product trade shows was approximately $686 million, exhibit square footage rose
17% from 1997, the number of exhibiting firms increased 26% from 1997 and
attendance at such shows rose 20% from 1997.

ZD Strategy

  ZD'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. The key elements of
ZD's strategy are:

 Focus On The Technology Market

  ZD believes that its focus on the technology market provides it with
substantial opportunities to attract both audiences and advertisers.

                                       95
<PAGE>

 Develop The Most Comprehensive, Objective And Authoritative Content

  ZD strives to produce the most differentiated, high quality content to
attract category brand-specifiers and decision-makers. ZD Labs, its computer
testing facility, enables ZD to provide reliable and authoritative product
evaluations to the business and consumer markets. The ability to provide
focused audiences with targeted information attracts leading advertisers and
exhibitors to ZD's products and services.

 Build Brand Strength

  ZD seeks growth in its core portfolio of leading brands, such as PC Magazine,
PC Week and COMDEX. ZD seeks to expand its market share of audiences and
advertisers while enhancing the quality and accessibility of its content and
marketing services. Ziff-Davis Inc.'s variety of business platforms enables ZD
to offer multiple media presentations of its branded content.

 Leverage Multiple Media Marketing Platforms

  ZD believes that the scope and depth of Ziff-Davis Inc.'s products and
services across multiple media platforms creates growth opportunities exceeding
those that ZD's businesses could achieve independently. Such opportunities
include the leveraging of strong relationships with advertisers in one media
platform into other platforms, cross-marketing products and services to the
audiences of its different platforms and packaging integrated marketing
products across all platforms for large advertisers. We believe that ZD has a
competitive advantage over single platform providers because of its ability to
offer clients multiple platform marketing solutions.

 Launch New Products And Services

  ZD believes that rapid advances in technology will create additional growth
opportunities to launch new products and expand its audience and advertiser
base. ZD seeks to identify new audiences and develop products and services that
respond to their informational needs. ZD believes that the scope of its
operations and its experience in launching new products across multiple media
platforms and geographic regions enable it to more readily achieve market
acceptance for new products and services.

 Expand Global Reach

  ZD intends to leverage its brand recognition and multinational experience to
expand further into overseas markets, focusing on key markets that have size
and growth characteristics to support ZD's strategy of cross-media operations.
ZD seeks to further expand internationally through the launch overseas of
proven U.S. properties, joint ventures and licensing arrangements with local
operating partners and selective acquisitions.

  ZD 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 repay indebtedness. See "ZD Management's Discussion
and Analysis of Financial Condition and Results of Operations".

Print Publishing

  ZD is a leading computer-related magazine publisher, with 26 primary U.S. and
international titles, including its joint ventures, and over 50 licensed
publications, totaling more than 75 publications distributed worldwide. ZD's
publications have a combined circulation of approximately seven million primary
readers worldwide. Approximately 61.5% of ZD's total revenue for the year ended
December 31, 1998, was attributable to its print publishing business. ZD's
magazines are designed to appeal to a target audience of sophisticated
customers in the business and consumer markets by providing high-quality
editorial content. ZD produces monthly magazines that provide comparative,
laboratory-based product reviews and news weeklies that provide product and
industry news and analysis. ZD also serves the developing market for lifestyle
and entertainment publications that focus on technology. ZD's publications also
include magazines related to the electronic gaming industry that ZD acquired
from Sendai Publishing Group, Inc. in May 1996.

  ZD believes its leading position in the computer publishing market is based
upon:

  . Leading Brands in Key Categories. In 1997, ZD's PC Magazine, PC Week and
    Computer Shopper magazines were the top three computer magazines in the
    U.S. and among the top 25 U.S. magazines, each as measured by total
    revenue.

  . Strength in Advertising, Circulation and Newsstand Sales. In 1997, ZD
    accounted for 36.8% of all advertising and circulation dollars spent in
    computer periodicals. ZD's U.S. publications have a total circulation of
    approximately six million primary readers, and ZD has a worldwide
    circulation of approximately seven million primary readers. In 1998, PC
    Magazine's circulation was greater than that of Business Week, Fortune or
    Forbes. With respect to newsstand sales, ZD's publications accounted for
    50.1% of all computer magazines sold in the first six months of 1998.

  . High Quality Editorial Content. ZD's top editors and columnists are
    supported by laboratory-testing facilities, producing widely acknowledged
    authoritative benchmarks for determining product quality. ZD's
    comprehensive content attracts focused audiences, thereby attracting
    leading advertisers and exhibitors to its products and services.

  . Successful Development of New Publications for Emerging Sectors. ZD has
    successfully introduced or acquired publications targeted at the consumer
    market (FamilyPC and Computer Gaming World), technology lifestyle (Yahoo!
    Internet Life), Internet professionals (Inter@ctive Week) and resellers
    (Sm@rt Reseller).

 Corporate Sales

  ZD's corporate sales team integrates its marketing activities into one
cohesive resource for its largest customers. The corporate sales group,
originally established to provide discounts for advertisers buying across two
or more magazine titles, has been expanded to allow marketers to reach their
target buyers through any combination of Ziff-Davis Inc.'s business platforms.
Currently 27 professionals in U.S. corporate sales coordinate major
advertisers' campaigns across Ziff-Davis Inc.'s multiple platforms.

 Editorial, Laboratory Testing And Benchmark Software

  ZD seeks to develop and maintain a high level of technical expertise to
provide quality technology content. ZD's editorial personnel includes award-
winning editors and experts. ZD believes its publications are widely regarded
as a reliable source of objective product evaluations and industry news because
of the quality and reputation of its laboratory tests. To maintain impartiality
and objectivity in its product reviews, ZD has policies governing separation of
editorial functions from advertising sales functions and restricts trading in
securities of technology-related companies by its journalists.

  ZD is committed to laboratory-based product testing as an integral part of
its editorial mission. For the year ended December 31, 1998, ZD spent over $11
million in laboratory testing. The ZD Labs staff works with testers from many
of ZD's different publications to provide comprehensive, objective test results
to assist buying decisions. In addition to the core ZD Labs staff, the PC
Magazine, PC Week, Computer Shopper and PC/Computing publications maintain
their own staff and/or testing space. The ZD Labs testing facility tests
thousands of products and systems each year and conducts large-scale tests to
simulate corporate installations. ZD believes ZD Labs gives it a competitive
advantage in terms of staffing, equipment and access to the technology
necessary to effectively evaluate products.

  ZD Labs produces the core, publicly available and widely distributed
benchmark software that its publications use to measure the performance of PCs,
Macintosh systems and servers. ZD's benchmarks have become industry standards
among major buyers of computer and Internet-related technology.

 Sources Of Print Publishing Revenue

  ZD's publications are generally either paid-circulation magazines--which
generate revenue from newsstand sales, subscriptions and advertising--or
controlled-circulation publications--which are distributed free of charge to
qualified information technology professionals, generate revenue principally
from advertising sales and provide valuable demographic information to ZD.

  Advertising Sales. ZD seeks to assist its advertisers in maximizing the
return on their marketing investment. Advertising sales accounted for 77.6% of
ZD's total print publishing revenue for the year ended December 31, 1998. The
ZD sales force uses market research tools, such as ZD's BrandTrak and ZDNet's
InternetTrak services, to inform clients about overall industry trends.
BrandTrak is a survey that is conducted every six months of

                                       99
<PAGE>

subscribers to five ZD publications and three European publications in order to
track purchasing behavior by brand. InternetTrak is a quarterly marketing
survey of Web users in the U.S. that tracks Web users and their online
activities. ZD's sales staff provides customer service, research, promotional
support and value-added programs for advertisers.

  Circulation. ZD maintains centralized circulation operations, enabling it to
capitalize on its successful practices on a timely basis across all
publications. ZD strives to increase its readership by building relationships
with distributors, retailers and subscribers. Revenue from circulation of ZD's
paid-circulation magazines accounted for 19.6% of ZD's total print publishing
revenue in 1998. This was comprised of subscription sales (10.2% in 1998) and
newsstand sales (9.4% 1998). ZD's publications have a total circulation of
approximately seven million primary readers worldwide.

  ZD's newsstand strategy focuses on developing strong relationships with key
distributors and large retail accounts. For example, ZD is the principal
supplier of computer technology publications to Warner Publisher Services, a
division of Time Warner Inc. In addition, ZD has preferred distribution
arrangements with large retailers including WalMart, Staples and Barnes &
Noble. These arrangements, which are terminable at will without notice, include
prominent magazine displays to strengthen ZD's brand identity.

  ZD's subscription strategy is to maintain a highly focused readership and
increase subscriber loyalty and renewal rates. This strategy provides ZD's
advertisers with access to a precisely focused target audience.

  Licensing and Joint Ventures. In its international publications, ZD seeks to
maximize global reach, maintain content quality and reduce the cost of entering
new markets. Through subsidiaries, ZD currently has publishing operations in
France, the United Kingdom and Germany. ZD also has over 50 licensed
publications worldwide. ZD's licenses are generally three to five year
agreements that provide for a minimum annual royalty against a percentage of
revenue. ZD also operates with a number of joint venture partners, including
IDG in the U.S., Richina Media Holdings and other local agencies in China and
APN Computing Group in Australia.

 U.S. Publications

  Business Magazines. In the U.S. market, ZD publishes seven computer
publications directed to business buyers, including four paid-circulation
magazines and three controlled-circulation weeklies or bi-weeklies. Each
publication produces authoritative, independent guidance that ZD believes is
generally considered to be the primary product resource in its market segment.
Macworld is published by Mac Publishing L.L.C., a ZD joint venture with 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

                                      100
<PAGE>

37.8% of all computer advertising revenue in directly competitive U.S.
publications in 1998. PC Magazine also produces two newsstand-only specials:
Your New PC (buying advice for less sophisticated computer buyers) and
InternetUser (reviews of Internet products).

  PC/Computing offers reviews of computer products, focusing on productivity
and usability. A monthly publication, it is one of only three computer
magazines to have reached a circulation of over one million readers.

  Computer Shopper provides buying advice, product evaluations and technology
coverage, including availability, pricing, specifications and configurations of
thousands of computer products. Computer Shopper has a newsstand circulation of
approximately 260,000 (the largest newsstand sales of any computer
publication).

professionals at large corporate computing sites with timely information on
products, companies and general industry news. PC Week has a controlled
circulation of over 400,000.

  Inter@ctive Week provides Internet and telecommunications professionals with
information on products, events, services, strategies, alliances and key
players. With a controlled circulation of over 150,000, Inter@ctive Week became
one of the leading publications for the digital communications technology
industry in less than three years.

  Sm@rt Reseller, a bi-weekly publication, provides value-added resellers,
system integrators, distributors, Web developers and Internet service providers
with in-depth news and analysis on business and technology. Sm@rt Reseller
currently has a controlled circulation of over 65,000.

evaluations, reviews and information about Macintosh products, supported by a
product testing facility which ZD believes is the most advanced in the
Macintosh industry. Macworld has a qualified circulation of over 500,000.

consumer market in order to meet the varying needs of computer enthusiasts, net
surfers, family buyers and gamers.

and software and thereafter ensure that they get a rewarding, productive and
educational experience from them.

 Paper And Printing

  ZD maintains strong relationships with its paper suppliers and printing
companies. ZD's main paper suppliers for its U.S. publications are Bowater,
Blandin, Champion, Consolidated and Fraser, which provided 8%, 13%, 38%, 15%
and 12%, respectively, of ZD's paper supply in 1998 as measured by tonnage. Its
paper supply contracts are generally two-to-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. ZD has relationships with a number of
printing companies, including R.R. Donnelley, Brown, Quadgraphics and Quebecor.
Approximately 46% of ZD's total printing expenditures for its U.S. publications
are with R.R. Donnelley, which has a number of alternative printing sites.
Printing contracts are generally two-to-three year agreements.

Trade Shows and Conferences

  ZD is a leading producer of trade shows, conferences and customized marketing
and educational programs for the computer industry in the U.S. Approximately
25.6% of ZD's total revenue in 1998 was attributable to its trade show and
conference business. ZD

                                      102
<PAGE>

produces the industry-wide COMDEX events, which ZD's predecessor acquired in
April 1995, other segment-focused trade shows and conferences and customized
events for specific clients. ZD produced over 50 trade shows and conferences in
1998.

  The COMDEX/Fall event, held in the fourth quarter of each year, has been held
for 19 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 1998, ZD estimates that over two million people attended its trade shows and
conferences worldwide. In addition to COMDEX/Fall, held annually in Las Vegas,
ZD produces 18 other COMDEX events in 13 countries.

  In 1998, ZD produced 11 segment-focused "NetWorld+Interop" and "Seybold
Seminars" trade shows in 9 countries. The NetWorld+Interop trade shows focus on
the networking/interconnectivity segment of the computer industry and the
Seybold Seminars focus on technologies for publishing and graphic
communications. ZD also produces the following segment-focused trade shows:

  . WINDOWS WORLD, in conjunction with Microsoft Corporation,

  . EXPO COMM, servicing the worldwide telecommunications industry,

  . CommUnity, for the emerging corporate integrated data, voice and video
    segments,

  . COMDEX/Enterprise, focusing on solutions for the large corporate
    information technology infrastructures,

  . Java SM Business Expo SM, sponsored by Sun Microsystems, Inc. and
    focusing on the full range of Java(TM) technology for information
    technology professionals and

  . Support Services Conference & Expo, focusing on technology for help desk
    and information technology support services.

  ZD also produces customized conferences that are designed to meet the
marketing needs of specific clients. For example, ZD produced the JavaOne
series of conferences for Sun Microsystems, Inc., which were designed to
introduce Java technology software to the developer community.

  Attendees at ZD's trade shows and conferences cover a wide range of
participants from the computer industry, including manufacturers, distributors,
dealers, retailers, as well as value-added and other resellers and large
corporate end-users. Each event includes an extensive conference program,
providing a forum to exchange 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. ZD estimates that in 1998 over
8,000 companies participated as exhibitors in its trade shows and conferences.

 Sources Of Trade Show And Conference Revenue

  Exhibitor space fees accounted for 66.8% of ZD's total trade show and
conference revenue for 1998. ZD believes most trade show producers receive
virtually all of their revenue from the sale of exhibitor space fees. ZD has
actively sought to increase its revenue from other sources, including attendee
fees, which accounted for 33.2% of all trade show and conference revenue in
1998.

  All exhibitors pay the same price per square foot of booth space, regardless
of the exhibit hall selected or the location or size of the booth. Typically, a
majority of exhibitors at

                                      104
<PAGE>

each trade show commit to booth space for the next year's show. ZD encourages
this commitment through a prioritized booth selection procedure based upon
seniority. 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.

  Attendee fees accounted for 14.1% of ZD's trade show and conference revenue
for 1998, primarily from NetWorld+Interop and Seybold Seminars events. Most
COMDEX attendees are invited guests of exhibitors who receive complimentary
admission tickets from ZD for their customers and key prospects. This helps
exhibitors ensure that their best customers and prospects will attend.

  Advertising revenue from ZD's trade shows and conferences is derived
principally from five products:

  . a daily newspaper distributed during the show,

  . the Program Exhibits Guide,

  . the Preview, a newspaper distributed to pre-registrants and certain prior
    year attendees before the show,

  . advertising billboards and banners and

  . exhibitor logo products that are sold to exhibitors to increase booth
    traffic and name recognition.

  ZD also maintains a continuously updated database containing the names and
certain demographic information on its 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
from their development and introduction to commercial maturity. Many of the
most significant computer product launches over the past 19 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 1998, COMDEX/Fall had approximately 1,500 exhibiting companies occupying 1.2
million net square feet of exhibit space and 200,000 attendees. COMDEX/Spring,
which was launched in 1981, is a smaller version of the fall event. In 1998, it
was held in Chicago and had approximately 560 exhibiting companies and over
85,000 attendees. For the last eight years, ZD, in cooperation with Microsoft
Corporation, has produced a WINDOWS WORLD trade show concurrently with
COMDEX/Spring.

  In 1993, ZD began launching additional COMDEX events in order to capitalize
on the international recognition of the COMDEX brand name. In 1998, other
COMDEX events were held 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

  NetWorld+Interop is the largest of ZD's segment-focused trade shows and is
the leading show for professionals in the rapidly growing field of computer
networking. NetWorld+Interop places strong emphasis on the quality of its
conference programs and has become a leading educational forum for the Internet
and enterprise computing communities. The largest NetWorld+Interop event is
held annually in May in Las Vegas. Each NetWorld+Interop trade show features
InteropNet, a live, multi-platform network that interconnects exhibitors to one
another and to the Internet. In 1998, the NetWorld+Interop Las Vegas event had
approximately 700 exhibiting companies occupying 475,000 net square feet of
exhibit space and 55,000 attendees. The NetWorld+Interop Atlanta event, held in
October each year, is only slightly smaller in all categories. In 1998,
NetWorld+Interop events were held in Las Vegas, Atlanta, Singapore, Tokyo,
London, Sao Paulo, Paris and Sydney.

 Seybold Seminars

  ZD's Seybold Seminars are also segment-focused trade shows, providing
information and education 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 Seminars series is held
annually each Fall in San Francisco. In 1998, this Seybold Seminars show had
approximately 350 exhibiting companies occupying 150,000 net square feet of
exhibit space and 38,000 attendees. Other Seybold Seminars events are held in
New York and Tokyo.

Television

  In order to expand its media platforms, Ziff-Davis Inc. entered into a
license and services agreement to manage ZDTV for MAC Holdings, a company that
is wholly owned by Mr. Masayoshi Son, who is a director of Ziff-Davis Inc. and
principal stockholder of SOFTBANK Corp. In February 1999, Ziff-Davis Inc.
acquired ZDTV and sold a one-third interest in ZDTV to Vulcan Programming,
Inc., an entity owned by Paul G. Allen, for $54 million.

  ZDTV, which was launched in May 1998, is the first 24-hour cable television
channel and integrated Web site focused exclusively on computers, technology
and the Internet. ZDTV targets 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
and the Internet. ZDTV's programming includes educational features, product
evaluations, gaming tips and strategies, current events and other
entertainment. ZDTV also features live interactive programming, allowing
viewers to participate through simultaneous Web programming on ZDTV.com. ZDTV
reached approximately 9.6 million homes at December 31, 1998 according to ZDTV
estimates. In addition, ZDTV creates customized programming for third parties,
including the regional Emmy award-winning "The Site" with MSNBC and "21st
Century Home" with Home & Garden Television.

Management's Discussion and Analysis of Financial Condition and Results of
Operations" and ZD's Combined Financial Statements.

Education

  ZD publishes 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. ZD believes its education offerings extend ZD's reach and
brand reputation while permitting it to attract and retain customers.

  ZD produces software-specific newsletters and technology information, with
approximately 40 titles. 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.

  ZDU is an Internet-based technology educational service through which ZD
provides interactive instructor-led training to subscribers. The ZDU service is
part of ZD but is closely integrated with ZDNet.

Market Research

  ZD's market research division develops, analyzes and compiles a wide variety
of information on computer technology issues ranging from current technical
aspects to decision making trends. The ZD Market Intelligence, or ZDMI, unit
focuses on installed and planned technology hardware and software purchases. It
is a leading source in North America and Europe of fact-based information for
the computer and communications industries. ZDMI is an important part of ZD's
effort to be a single source marketing solution, as it provides marketing
customers with important targeting information. ZDMI's databases are built from
more than 45,000 telephone interviews per month and contain data on installed
and planned computer and communications products and services at over 350,000
business sites in the U.S., Canada and eight European countries, according to
ZD estimates. ZDMI identifies and targets customers by tracking current
activity and market share in the business, home and reseller channels.
Customers use ZDMI's services to make important marketing decisions.

  ZD also identifies and analyzes trends in the decision making process for
computer technology consumers. This information indicates the criteria people
focus on to select products beyond technical product specifications. ZD's
market research division also consolidates information obtained in each of the
databases maintained by other operating divisions within ZD and ZDNet, so that
each division can offer Ziff-Davis Inc.'s clients a wide range of information
to meet their marketing needs across multiple platforms.

Competition

  ZD competes with a wide range of companies for each of its products and
services. The magazine publishing business is highly competitive. ZD faces
broad competition from other technology publishers and from other media
companies such as business, news and general interest magazines. Computer and
technology publishers that directly compete with ZD in the U.S. include IDG,
CMP and Imagine Media. ZD also competes with various computer and technology
publishers in the international markets where 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.

  ZD also faces competition in its trade show and conference business,
primarily from several significant trade show management companies. These
include Miller Freeman, Mecklermedia and IDG. Competitive factors in this
business include quality of conference content, organizational efficiency and
quality and number of exhibitors and attendees.

  ZD'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.

  ZD's education division competes with a variety of education providers,
including vendor-supplied training materials and traditional classroom-based
computer training.

  ZDTV is the first 24-hour cable television channel and integrated Web site
focused exclusively on computers, technology and the Internet, and as such, it
is not expected to face direct competition in the near future. However, ZDTV
does compete with a variety of general and special interest television
programs. In addition, the market for television programming in general is
highly competitive, with many programming producers competing for channel
carriage, advertisers and audiences.

Trademarks

  ZD has developed strong brand awareness for its principal publications, trade
shows and other products and services. Accordingly, ZD 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. ZD generally registers its material trademarks in
the U.S. 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 where ZD's publications and services are available.

  ZD 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. ZD 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 its business, financial condition or
results of operations.

Employees

  As of December 31, 1998, ZD had a total of 2,889 employees. Of these
employees, 621 were engaged in U.S. magazine publishing activities, 397 in
international publishing activities, 505 in trade shows and conferences, 407 in
education activities, 436 in market research and 523 in central services. None
of ZD's U.S. employees is represented by a labor union. ZD considers its
relationships with its employees to be satisfactory.

Facilities

  ZD's world headquarters are located in New York and ZD has over 50 editorial,
production and sales offices and computer labs in many other cities in the U.S.
and around the world. ZD's other principal offices are located in the Boston
and San Francisco metropolitan areas. ZD and Ziff-Davis Inc. do not own real
property that is material to its business and Ziff-Davis Inc. leases all but
one of its offices from third parties. ZD believes that its properties, taken
as a whole, are in good operating condition and are suitable and adequate for
its current operations, and that suitable additional or alternative space,
including space available under lease options, will be available at
commercially reasonable terms for future expansion.

           SELECTED HISTORICAL CONSOLIDATED FINANCIAL AND OTHER DATA

  The following table presents Selected Historical Consolidated Financial and
Other Data for Ziff-Davis Inc. as of and for the years ended December 31, 1995,
1996, 1997 and 1998. This data was derived from the Consolidated Financial
Statements of Ziff-Davis Inc. included elsewhere in this prospectus. An
affiliate of Ziff-Davis Inc. acquired a print publishing business, "ZDI", on
February 29, 1996; the data does not include results from the acquired business
for periods before the date of acquisition. However, because ZDI represents
Ziff-Davis Inc.'s principal operations, the following table also presents
Selected Historical Combined Financial and Other Data for ZDI as of and for the
years ended December 31, 1994 and 1995 and as of and for the two month period
ended February 28, 1996. The data as of and for the year ended December 31,
1995 and as of and for the two months ended February 28, 1996 was derived from
the audited Consolidated Financial Statements of ZDI. ZDI data as of for the
year ended December 31, 1994, was derived from ZDI's unaudited financial
statements. On May 4, 1998, Ziff-Davis Inc. completed a reorganization
described in Note 2 to the Consolidated Financial Statements of Ziff-Davis
Inc.; results for periods before the reorganization are not directly comparable
to results for periods after the reorganization. This table should be read in
conjunction with the Selected Historical Financial and Other Data, Management's
Discussion and Analysis of Financial Condition and Results of Operations for
each of ZDNet, ZD and Ziff-Davis Inc. and Financial Statements for each of
ZDNet, ZD and Ziff-Davis Inc. beginning on pages F-5, F-33 and F-79 of this
prospectus, respectively.

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

Revenue

  Ziff-Davis Inc. had net revenue of $1.109 billion for 1998. A substantial
portion of Ziff-Davis Inc.'s revenue is derived from the sale of advertising,
which in 1998 accounted for 51.6% of total revenue. No single advertiser has
comprised more than 3.0% of Ziff-Davis Inc.'s advertising revenue during any of
the last three years. However, Ziff-Davis Inc.'s top 20 advertisers accounted
for 37.1% of total advertising revenue for 1998.

  In the publishing segment, Ziff-Davis Inc.'s principal sources of revenue are
advertising (64.4% of 1998 total publishing revenue), circulation (18.7%) and
other (16.9%). Circulation comprises both paid subscriptions (10.9%) and
newsstand sales (7.8%) while other includes educational and training materials
(7.4%) and market research studies (7.1%) with the balance primarily consisting
of royalties, reprints and other miscellaneous sales. In the events segment,
revenue is derived from two principal sources: sale of exhibit space (66.8% of
1998 total segment revenue) and attendee conference and seminar fees (14.1%).
Unlike many trade show producers, Ziff-Davis Inc. derives a significant portion
of its trade show revenue from other sources (19.1%), including advertising in
show-related publications, billboards, banners, fees from managing customer-
sponsored events and other show-related activities. Ziff-Davis Inc. believes
these other sources will continue to be an important growth area, particularly
for its content-focused events. In the Internet segment, Ziff-Davis Inc.'s
principal source of revenue is from advertising (86.0% of total Internet
revenue for 1998). The Internet segment also derives revenue from subscription-
based fees and services (14.0% of total Internet revenue in 1998).

Cost of operations

  In the publishing business, the principal components of Ziff-Davis Inc.'s
production costs are raw materials, printing and distribution, which
represented 34.5%, 38.0% and 27.2%, respectively, of total 1998 publishing
production expenses. Ziff-Davis Inc.'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 also "Risk
Factors--Other Ziff-Davis Inc. Risks--Ziff-Davis Inc. May Be Adversely Affected
By Fluctuations in Paper and Postage Costs" and "--Inflation and Fluctuations
in Paper Prices and Postage Costs". The principal components of production
costs within the events business are the costs of renting and preparing the
facilities to hold the events (46.8% in 1998), direct mail and the related
costs for promotion of the events (37.0% in 1998) and program development and
presentation costs (13.4% in 1998). Production costs in the Internet segment
consist primarily of third party web hosting costs.

  The other principal operating costs for Ziff-Davis Inc. are selling, general
and administrative expenses, including editorial costs. Included in these costs
are salaries, sales commissions and benefits (55.4% in 1998) along with
marketing and promotion expenses related to advertising and circulation (19.7%
in 1998).

Factors affecting future periods

  Ziff-Davis Inc.'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 expenditures by Ziff-Davis Inc.'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 conferences and providers of other
technology information services. Accordingly, Ziff-Davis Inc. may experience
fluctuations in revenue from period to period. Many of Ziff-Davis Inc.'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
pressures and temporary surpluses of inventory. Revenue and profitability are
also influenced by product mix and the timing and frequency of Ziff-Davis
Inc.'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, Ziff-Davis Inc.'s revenue from year to year
may be affected by the number and timing of new product launches. If Ziff-Davis
Inc. concludes that a new publication, trade show or service will not achieve
certain milestones with regard to revenue, 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--Other Ziff-Davis Inc. Risks--To Remain Competitive
Ziff-Davis Inc. Must Constantly Expand And Develop New Products And Services.
This Is Inherently Risky And Expensive".

  On February 4, 1999, Ziff-Davis purchased ZDTV. This purchase will affect
Ziff-Davis Inc.'s results in future periods. See "--ZDTV" below for certain
summary pro forma and other information about this purchase.

  Ziff-Davis Inc. expects to recognize compensation expense of approximately
$21.3 million as a result of certain options granted on December 21, 1998 and
January 29, 1999. Such compensation expense will be recognized over the vesting
period of the options. The 1999 compensation expense related to these options
is expected to be approximately $5.5 million. See Note 13 to Ziff-Davis Inc.'s
Consolidated Financial Statements in this prospectus.

  Ziff-Davis Inc. expects to acquire the remaining 30% interest in GameSpot in
exchange for ZDNet stock valued at $9 million, based on the initial public
offering price; provided that, the stockholders of GameSpot will not receive
less than 600,000 shares of ZDNet stock. At a price of $19.00 per share, this
acquisition will result in additional annual amortization of approximately $1.3
million per year. The effect of this acquisition and the shares expected to be
issued in connection therewith are not reflected elsewhere in this prospectus.

Presentation of Financial Information

  Ziff-Davis Inc. is comprised of certain operations which were acquired at
various times and completed a reorganization in May 1998. See Notes 1 and 2 to
the Consolidated Financial Statements in this prospectus.

Results of Operations

  The table below presents the results of Ziff-Davis Inc. as if the assets and
operations acquired by affiliates of Ziff-Davis Inc. on February 29, 1996 (as
described in Note 1 to the Consolidated Financial Statement in this prospectus)
had been acquired on January 1, 1995. Purchase accounting adjustments relating
to that acquisition have been reflected through pro forma amortization,
interest and income tax adjustments, as described in note (1) to the table.
Although the 1996 presentation is not in accordance with generally accepted
accounting principles, management believes it presents the most meaningful
basis of comparison. The financial information presented below may not
necessarily reflect the results of operations which would have occurred had the
February 29, 1996 acquisition been completed on January 1, 1995.

(1) The February 29, 1996 acquisition gave rise to different bases of
    accounting for the period after the acquisition as compared to 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 above numbers assume that the acquisition took place on
    January 1, 1995; therefore, depreciation and amortization, interest expense
    and net loss have been increased by approximately $6,386,000, $824,000 and
    $10,383,000, respectively for 1996.
(2) "EBITDA" is defined as income before provision for income taxes, interest
    expense, depreciation and amortization. EBITDA for the year ended December
    31, 1998 does not include a one-time restructuring charge of $52,239,000.
    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 Ziff-
    Davis Inc.'s operating performance or to cash flows as a measure of
    liquidity. Although Ziff-Davis Inc. 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, the EBITDA
    presented for Ziff-Davis Inc. may not be comparable to similarly titled
    measures reported by other companies.

Year ended December 31, 1998 compared with year ended December 31, 1997

 Revenue, net

  Revenue decreased by $44.9 million or 3.9% from $1,153.8 million in 1997 to
$1,108.9 million in 1998.

  Publishing--Revenue from publishing decreased by $51.1 million or 6.1% from
$834.0 million in 1997 to $782.9 million in 1998. This decline was primarily
due to the transfer of certain publications to a joint venture and the closure
of three publications due to the restructuring discussed below. The remainder
of the decrease was primarily due to lower advertising in business publications
partly offset by growth in advertising in consumer publications. Advertising
revenue was lower in business publications principally due to factors affecting
the computer technology industry during the year. Margin pressure on computer
equipment manufacturers, industry and product delays, lower demand in Asia and
a focus on the Year 2000 transition are contributing to a reduced demand for
advertising in Ziff-Davis Inc.'s magazines. Revenue from international
operations, which generated 10.2% of the segment's revenue, increased by $2.1
million primarily due to the launch of IT Week in the UK, partially offset by
lower advertising in business publications.

  Net revenue from MacUser and MacWeek magazines contributed to Mac Publishing
LLC were $32.5 million for 1997 but are no longer consolidated into Ziff-Davis
Inc.'s results for 1998. On May 1, 1998, Ziff-Davis Inc. acquired its joint
venture partner's 50% interest in FamilyPC magazine. Ziff-Davis Inc. now owns
100% of the magazine and its results are included in the consolidated results
from the acquisition date. Revenue from FamilyPC included in the 1998 results
was $11.1 million. Revenue related to the three publications closed as part of
the restructuring was $12.5 million lower in the fourth quarter of 1998 as
compared to the fourth quarter of 1997.

  Events--Revenue from events decreased by $17.6 million or 6.1% from $287.5
million in 1997 to $269.9 million in 1998. The decrease was primarily due to a
decline in revenue due to the discontinuation of certain "one-time" shows that
were held in 1997, lower ancillary revenue at COMDEX/Fall and lower square
footage sold at COMDEX/Spring. This decrease was partially offset by increased
revenue from increased square footage sold at Networld+Interop Las Vegas and
Java One due to an increased number of attendees.

  Internet--Net revenue increased 74.2% to $56.1 million for the year ended
December 31, 1998 from $32.2 million for the year ended December 31, 1997.
Revenue from advertising was 86% of net revenue for the year ended December 31,
1998 compared to 73% for the year ended December 31, 1997. Revenue from
advertising increased 104.2% to $48.2 million for the year ended December 31,
1998 from $23.6 million for the prior year. The increase in advertising revenue
was attributed to an increase in volume as both the number of advertisers and
the average monthly revenue per advertiser increased. Subscription-based fees
and services decreased by 6.9% to $8.0 million for the year ended December 31,
1998 from $8.6 million for the year ended December 31, 1997.

                                      114
<PAGE>

 Cost of production

  Production costs decreased by 6.1% or $19.9 million from $325.2 million in
1997 to $305.3 million in 1998.

  Publishing production costs decreased by $6.0 million or 2.7% from $221.4
million in 1997 to $215.3 million in 1998. The decrease was related to a
decline in the number of advertising pages produced.

  The cost of producing events decreased by $17.4 million or 17.4% from $99.5
million in 1997 to $82.1 million in 1998. The decrease was a result of lower
operational costs and re-negotiated contracts as well as the discontinuation of
certain "one-time" shows that were held in 1997.

  Internet production costs increased by $3.6 million or 83.7% from $4.3
million in 1997 to $7.9 million in 1998. The increase in production costs was
due to higher user traffic levels and increased editorial costs associated with
the launch of new content areas.

 Selling, general and administrative expenses

  Selling, general and administrative expenses increased by $3.3 million or
0.6% from $564.3 million in 1997 to $567.7 million in 1998. The increase was
due to expenditures to launch new products and increased advertising expenses.
The increase was partially offset by headcount reductions and efficiencies
attained through the integration of operations resulting from the
reorganization completed in May 1998, as well as costs eliminated by the
closure of three magazines in the fourth quarter of 1998.

 Depreciation and amortization

  Total depreciation and amortization decreased $2.4 million from $154.9
million in 1997 to $152.5 million in 1998. The decrease was a result of certain
assets being fully depreciated in 1997 and early 1998.

 Restructuring

  Margin pressure on computer equipment manufacturers, industry and product
delays, lower demand in Asia and a focus on the Year 2000 transition are
contributing to a reduced demand for advertising in Ziff-Davis Inc.'s
magazines, principally PC Magazine, PC/Computing, Computer Shopper and PC Week.
Ziff-Davis Inc. believes these factors are continuing.

  As a result of this reduced demand, in October 1998, Ziff-Davis Inc.
announced a restructuring program with the intent of significantly reducing its
cost base. Ziff-Davis Inc. incurred a pre-tax charge of $52.2 million for this
restructuring program. The charge was reported as a component of income from
operations for the fourth quarter of 1998. The charge included asset impairment
costs ($37.9 million), employee termination costs ($8.6 million) and costs to
exit activities ($5.7 million) principally resulting from the closing of three

                                      115
<PAGE>

publications, Windows Pro, Internet Business and Equip, and the reduction of
Ziff-Davis Inc.'s work force by 310 employees. The charge also included costs
resulting from the discontinuation of certain educational journals and trade
shows. The following sets forth additional detail concerning the principal
components of the charge:

  .  Asset impairment costs totaled $37.9 million. These costs included the
     write-off of intangible assets associated with the discontinued
     publications ($34.3 million) and trade shows ($2.9 million) as well as
     deferred expenses associated with the discontinued educational journals
     ($0.7 million).

  .  Employee termination costs related to severed personnel at the closed
     publications as well as a rationalization and resulting workforce
     reduction of the remainder of Ziff-Davis Inc.'s operations. Employee
     termination costs included payments for severance and earned vacation as
     well as the costs of outplacement services and the provision of
     continued benefits to personnel. As of December 31, 1998, $5.2 million
     of the $8.6 million related to these employee terminations had been
     paid.

  .  Costs to exit activities reflected the costs associated with the final
     closure of the discontinued publications ($1.8 million) and the costs to
     reduce office space under lease as a result of the reduced level of
     employees ($3.8 million).

 Interest expense, net

  Interest expense decreased by $46.9 million or 24.6% from $190.4 million in
1997 to $143.5 million in 1998. The reduction was due primarily to lower levels
of debt outstanding throughout the year, as well as the capitalization of
$908.7 million of intercompany debt as part of the reorganization.

 Other non-operating income, net

  Other non-operating income, net primarily reflects Ziff-Davis Inc.'s equity
share in earnings and losses from joint ventures and fees earned from
management of events not produced by Ziff-Davis Inc. This income decreased $0.5
million or 5.6% from $8.7 million in 1997 to $8.2 million in 1998 reflecting
reduced fees from managed events. The decline was partially offset by Ziff-
Davis Inc.'s equity share in earnings of MAC Publishing, LLC, an entity that
was formed in August 1997.

 Income taxes

  The 1998 income tax benefit of $26.4 million increased from $1.3 million
reported in 1997. The increase was due primarily to income tax benefits
generated from the losses with respect to the MAC Assets, which were not
deductible until Ziff-Davis Inc. purchased the MAC Assets from an affiliate on
May 4, 1998. The income tax benefit was also increased by a higher net loss for
the year ended December 31, 1998 compared to the net loss for the year ended
December 31, 1997.

 Net loss

  As a result of the changes described above, the net loss for the period
increased $6.6 million or 9.3% from $71.2 million in 1997 to $77.8 million in
1998.

<PAGE>

 EBITDA

  EBITDA for the year ended December 31, 1998 was $244.1 million compared to
$272.9 million for the year ended December 31, 1997. EBITDA for the year ended
December 31, 1998 does not include the $52.2 million restructuring charge.
Results were unfavorable as compared to 1997 due to a lower level of earnings
from advertising in the higher margin business publications partly offset by
improved results in the events segment and reduced losses in the Internet
segment. The improvement in the events segment was attributed to the absence of
losses from the discontinuance of certain "one-time" shows held in 1997 as well
as continued costs savings. Reduced losses from the Internet segment were the
result of revenue growth exceeding increases in expenses. The ratio of EBITDA
to revenue was 22.0% for 1998 compared to 23.7% in 1997.

Year ended December 31, 1997 compared with Pro Forma Year ended December 31,
1996

 Revenue, net

  Net revenue increased by $73.2 million or 6.8% from $1,080.6 million in 1996
to $1,153.8 million in 1997.

  Publishing--Net revenue from publishing grew by $37.4 million or 4.7% from
$796.6 million to $834.0 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. Increases in
advertising rates, generally ranging between 3.0% and 10.0%, 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.

  Events--Net revenue from events 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.

  Internet--Net revenue increased by $13.1 million or 68.6% from $19.1 million
for the pro forma year ended December 31, 1996 to $32.2 million in 1997. An
increasing percentage of ZDNet's net revenue was derived from advertising for
the year ended December 31, 1997, accounting for 73.3% of net revenue, compared
to 37.7% for the same period in 1996. The increased percentage of net revenue
derived from advertising in the later period reflects a continuation of ZDNet's
strategic shift from a business model based on subscription-based fees and
services to one based on advertising.

  Revenue from advertising increased $16.4 million or 227.8% to $23.6 million
in 1997 from $7.2 million for the pro forma year ended December 31, 1996. The
increase in

                                      117
<PAGE>

advertising revenue was attributable to increases in the number of advertisers,
the average expenditures per advertiser and increasing advertising rates. The
increase was evenly attributable to rate and volume increases. Subscription-
based fees and services decreased $3.3 million or 27.7% from $11.9 million in
1996 to $8.6 million in 1997.

 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 in 1997. 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 events increased $12.2 million or 14.0% from $87.3
million in 1996 to $99.5 million in 1997 primarily as a result of costs related
to new events launched in 1997.

  Internet production costs increased $1.3 million or 43.3% from $3.0 million
in 1996 to $4.3 million in 1997. The increase in production costs was due to
higher user traffic levels and increased editorial costs associated with the
launch of new content areas.

 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 events business which was announced in
the fourth quarter of 1997. Costs for the publishing segment rose 1.2% while
those for the events 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, net primarily reflects Ziff-Davis Inc.'s equity
share of earnings and losses from joint ventures and fees earned from
management of events not produced by Ziff-Davis Inc. This 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 in 1997 and $77.2 million in 1996),
non-deductible goodwill amortization ($10.2 million in 1997 and $8.6 million in
1996) 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 changes 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%.

Liquidity and Capital Resources

  As a result of the May 4, 1998 reorganization, Ziff-Davis Inc.'s intercompany
debt owed to Softbank was reduced to $83.1 million. Such indebtedness bears
interest at 9.9% and matures in February 2010. Concurrently with Ziff-Davis
Inc.'s initial public offering, Ziff-Davis Inc. issued and sold $250 million
aggregate principal amount of notes. In addition, Ziff-Davis Inc. entered into
a $1.35 billion credit facility, and borrowed $1.25 billion under such
facility, to provide additional funds for the repayment of intercompany debt to
Softbank and to provide for Ziff-Davis Inc.'s working capital requirements. The
balance of intercompany obligations owed to Softbank was converted to equity.
See Note 2 to the Consolidated Financial Statements in this prospectus.

  At December 31, 1998, Ziff-Davis Inc.'s outstanding total debt was $1,547.9
million, excluding unamortized discount, which consisted of $77.9 million due
to Softbank, $250 million in notes and $1,220.0 million under the credit
facility. Under its most restrictive covenant, Ziff-Davis Inc. could have
borrowed an additional $28,800,000 under the credit facility at December 31,
1998. For information concerning the terms of this debt, see "Ziff-Davis Inc.'s
Debt".

                                      119
<PAGE>

  Cash and equivalents were $32.6 million at December 31, 1998, an increase of
$2.3 million from $30.3 million at December 31, 1997. The increase was due to
factors described below:

  Cash provided by operations was $95.8 million for the year ended December 31,
1998 compared to a use of $3.4 million for the year ended December 31, 1997.
The increase from 1997 to 1998 was attributed to Ziff-Davis Inc.'s lower losses
before the restructuring charge and a decrease in funding to affiliates for the
1998 period.

  Cash used for investing activities for the year ended December 31, 1998
totaled $64.4 million compared to $44.2 million for the year ended December 31,
1997. The majority of these expenditures were for computer equipment and
leasehold improvements. Acquisitions and investments in the 1998 period relate
to Ziff-Davis Inc.'s acquisition of Sky TV, a tradeshow in Canada, an
additional 50% interest in Family PC magazine, a European marketing database
company as well as investments in Red Herring and Deja News. Acquisitions for
the year ended December 31, 1997 reflect the purchase of a 70% interest in
GameSpot.

  Cash used in financing activities totaled $29.1 million for the year ended
December 31, 1998, representing proceeds from the reorganization and initial
public offering of $1,863.3 million, net of transaction costs, and funding from
Softbank of $20.4 million offset by the repayment of debt and amounts due to
affiliates of $1,916.1 million. Cash provided by financing activities in 1997
amounted to $47.9 million representing capital contributions partly offset by
repayments of intercompany debt.

  Ziff-Davis Inc. had a working capital surplus of approximately $35.5 million
at December 31, 1998, compared to a working capital deficit of approximately
$371.1 million at December 31, 1997. Ziff-Davis Inc.'s balance sheet has
historically had a working capital deficit due to significant amounts due to
affiliates. Ziff-Davis Inc. also maintains a significant level of deferred
revenue generated from publication subscriptions paid in advance and
prepayments from trade show exhibitors. At December 31, 1998, Ziff-Davis Inc.
had deferred revenue of $152.1 million compared to $154.7 million at December
31, 1997. Deferred revenue does not represent a cash liability owed by Ziff-
Davis Inc., unless Ziff-Davis Inc. fails to deliver a magazine or cancels a
trade show, and generally does not affect Ziff-Davis Inc.'s ability to fund
day-to-day operations. Working capital increased as a result of the
reorganization and the initial public offering of Ziff-Davis Inc.'s common
stock which resulted in the repayment and conversion to equity of related party
obligations in connection therewith.

  On December 11, 1998, Standard & Poor's lowered its corporate credit and bank
loan ratings for Ziff-Davis Inc. to BB- from BB and its subordinated debt
rating for Ziff-Davis Inc. to B from B+. This downgrade had no impact on our
current borrowings. Although this downgrade may make future borrowings more
expensive, we do not believe this will have a material impact on our liquidity
or our access to credit markets.

  Ziff-Davis Inc. believes, based on its current level of operations and
anticipated growth, that Ziff-Davis Inc.'s ability to generate cash, together
with cash on hand and available lines

                                      120
<PAGE>

of credit, will be sufficient to make required payments of principal and
interest on Ziff-Davis Inc.'s indebtedness and to fund anticipated capital
expenditures and working capital requirements. However, actual capital
expenditures may change, particularly as a result of any acquisitions Ziff-
Davis Inc. may pursue. The ability of Ziff-Davis Inc. to meet its debt service
obligations and reduce its total debt will depend upon the future performance
of Ziff-Davis Inc.

Credit Facility

  Ziff-Davis Inc.'s credit facility, as amended, consists of a seven-year $400
million reducing revolving credit facility, a seven-year $450 million term loan
and an eight-year $500 million term loan. There are no scheduled reductions in
the revolving credit commitment or amortization under the term loan until
September 2000.

  For the reasons described under "--Restructuring" above, Ziff-Davis Inc's.
debt to EBITDA ratios at December 31, 1998 would have been above the levels
that had originally been required by its credit facility. On December 16, 1998,
the lenders of the $1.35 billion credit facility agreed to amend certain
provisions of that facility. The amended provisions include an increase in the
allowed leverage ratios. In return, Ziff-Davis Inc. agreed to pay a one-time
fee of $3.375 million and increase the interest rates on amounts borrowed under
the facility to rates currently ranging from LIBOR plus 2.875% to LIBOR plus
3.375% depending on the type of loan. Had the increased interest rates been in
effect for the period from Ziff-Davis Inc.'s initial public offering on April
28, 1998 to December 31, 1998, interest expense would have increased by
approximately $11.9 million. Based on the $1,220.0 million outstanding on
December 31, 1998, the annualized incremental interest is $18.0 million. This
increase in interest expense would reduce the amounts otherwise available to
fund ZD or ZDNet operations.

  Ziff-Davis Inc.'s credit facility exposes it to market risk with respect to
changes in interest rates. Ziff-Davis Inc. manages this risk through the use of
interest rate swap agreements, as described below. Through the use of these
swap agreements, Ziff-Davis Inc. has effectively established a fixed interest
rate for $550 million of the outstanding credit facility. Based on the $1,220.0
million outstanding under the credit facility at December 31, 1998, if the
LIBOR rate were to increase by 1%, Ziff-Davis Inc. would incur, after giving
effect to the swap agreements, an additional $6.7 million of annual interest
expense.

  For a description of the terms of the amended credit facility, see "Ziff-
Davis Inc.'s Debt".

Interest Rate Swaps

  On June 10, 1998, Ziff-Davis Inc. entered into interest rate swap agreements,
with an aggregate notional amount of $550 million. Under these swap agreements,
which commenced on August 10, 1998, Ziff-Davis Inc. receives a floating rate of
interest based on three-month LIBOR, which resets quarterly, and pays a fixed
rate of interest each quarter for the terms of the respective agreements. The
weighted average fixed rate Ziff-Davis Inc.

                                      121
<PAGE>

pays under these agreements is 5.85%. Ziff-Davis Inc. has entered into these
agreements solely to hedge its interest rate risk. At December 31, 1998, the
three-month LIBOR rate was 5.06%.

  These swap agreements are viewed by Ziff-Davis Inc. as risk management tools
and are not used for trading or speculative purposes. The notional amount of
$550 million does not represent a real amount exchanged by the parties, and
therefore, is not a measure of Ziff-Davis Inc.'s exposure through its use of
swap agreements. The fair values of these swap agreements were estimated by
obtaining quotes from brokers which represented the amounts that Ziff-Davis
Inc. would pay if the agreements were terminated at the balance sheet date.
While it is not Ziff-Davis Inc.'s intention to terminate these swap agreements,
these fair values indicated that the termination of the swap agreements would
have resulted in a loss of $15,627,000.

  By nature, swap agreements involve credit risk, due to the possible
nonperformance by counterparties. To mitigate this risk, Ziff-Davis Inc. enters
into swap agreements with major financial institutions and diversifies the
counterparties used as a means to limit counterparty exposure and concentration
of risk.

ZDTV

  In July 1997, Ziff-Davis Inc. entered into a license and services agreement
to develop ZDTV for MAC Holdings, a company that is wholly owned by Mr.
Masayoshi Son, who is a director of Ziff-Davis Inc. and principal stockholder
of SOFTBANK Corp. Under this agreement, Ziff-Davis Inc. agreed to fund ZDTV's
operations through unsecured advances and was granted an option to purchase
ZDTV for a price equal to MAC Holdings' investment plus 10% per annum for the
period of investment. On January 15, 1999, Ziff-Davis Inc. exercised this
option and on February 4, 1999, purchased ZDTV at a purchase price of $81.4
million. Ziff-Davis Inc. paid approximately $32.8 million of the purchase price
in cash, funded on February 5, 1999, and paid the remainder by applying
approximately $48.6 million in advances owed to it by MAC Holdings through
December 31, 1998. Ziff-Davis Inc. also agreed to be responsible for the
funding of ZDTV during the period in 1999 prior to the purchase which will be
accounted for as additional purchase price. The cash portion of the purchase
price was funded by an advance from ZDTV to Ziff-Davis Inc., pursuant to the
ZDTV cash management system, of the funds invested in ZDTV by Vulcan
Programming described below. In connection with its acquisition of ZDTV, Ziff
Davis Inc. assumed MAC Holdings' obligations under an option granted to
DirectTV to purchase 5% of ZDTV for $15 million, subject to adjustment.

  Ziff-Davis Inc. currently has certain long-term agreements to distribute ZDTV
via satellite. Historically, start-up cable television channels have required
substantial investment and there can be no assurance that ZDTV will ultimately
obtain sufficient cable carriage and commercial acceptance to be profitable.
The following unaudited summary pro forma information assumes that the
acquisition of ZDTV and the sale of a one-third interest in ZDTV to Vulcan
Programming referred to below had been consummated on January 1, 1998.
Adjustments for ZDTV transactions include the operating results of ZDTV,

  ZDTV's cash requirements are currently expected to be approximately $50
million for 1999. The $54 million invested in ZDTV by Vulcan Programming will
be used to fund ZDTV and thereafter cash requirements will be funded by the
partners or by third parties.

  Ziff-Davis Inc. intends to file appropriate financial statements and pro
forma information regarding ZDTV on or before April 20, 1999 as set forth in
its Form 8-K filed with the SEC on February 19, 1999.

Vulcan Transactions

  On February 5, 1999, Vulcan Programming, an entity owned by Paul G. Allen,
purchased a one-third interest in ZDTV for $54 million. On March 4, 1999,
Vulcan Ventures, the investment vehicle of Paul G. Allen, purchased
approximately three million shares of Ziff-Davis Inc. common stock for $50
million.

Seasonality

  Historically, Ziff-Davis Inc.'s business has been seasonal as a significant
portion of annual revenue has occurred 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,
1998. In the opinion of Ziff-Davis Inc.'s management, this unaudited
information has been prepared on a basis consistent with the audited
Consolidated Financial Statements appearing elsewhere in this prospectus 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 Consolidated Financial Statements and related notes
thereto. The operating results for any quarter are not necessarily indicative
of results for any future period.

    $52,239,000. 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 Ziff-Davis Inc.'s operating performance or to cash flows as a
    measure of liquidity. Although Ziff-Davis Inc. 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, the
    EBITDA presented for Ziff-Davis Inc. may not be comparable to similarly
    titled measures reported by other companies.

Inflation and Fluctuations in Paper Prices and Postage Costs

  Ziff-Davis Inc. continually assesses the impact of inflation and changes in
paper prices. Ziff-Davis Inc. 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 and then decreased in 1997.
During 1998, paper prices were relatively flat. Management anticipates that
paper prices will remain relatively stable in 1999. Ziff-Davis Inc. will
continue to monitor the impact of inflation and paper prices and will consider
these matters in setting its pricing policies. Ziff-Davis Inc. 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, Ziff-Davis Inc. had not entered, and does not currently
plan to enter, into long-term forward price or option contracts for paper.
Management estimates postage costs will increase approximately 3.5% in 1999.
See "Risk Factors--Other Ziff-Davis Inc. Risks--Ziff-Davis Inc. May Be
Adversely Affected By Fluctuations in Paper and Postage Costs" and "ZD
Description of Business--Paper and Printing".

Year 2000 Readiness Disclosure

  During 1997, Ziff-Davis Inc. began a review of its computer systems and
software to identify systems and software which might malfunction due to
misidentification of the Year 2000. Ziff-Davis Inc. is using both internal and
external resources to identify, test, correct and reprogram systems and
software for Year 2000 readiness.

  At December 31, 1998, Ziff-Davis Inc. was in the research and validation
phase of its Year 2000 project for information technology, or IT, systems and
non-IT systems. This phase consists of research and validation of all
infrastructure, hardware and software, including platform, wide-area network
and local-area network components. Research for non-IT systems includes
identifying systems that include embedded technology, such as micro-
controllers, which are not Year 2000 compliant.

  Ziff-Davis Inc. has identified critical systems and applications that will
either be validated for compliance through formal documentation, through
vendors or through testing. Ziff-Davis Inc. will enter the testing phase of its
infrastructure, hardware, software and databases in the first quarter of 1999
and plans to complete such phase by September 1, 1999. Contingency plans will
be developed for any systems or platforms that are known to be non-compliant as
of September 1, 1999.

  Some of Ziff-Davis Inc.'s computer systems and databases, including its
subscription fulfillment and payroll systems, are managed by third parties
under contractual arrangements. Ziff-Davis Inc. currently has no Year 2000
compliance problems known to it relating to third parties. Ziff-Davis Inc. has
requested those third parties with which Ziff-Davis Inc. has material
relationships in the first quarter of 1999 to advise it as to whether such
third parties anticipate difficulties in addressing Year 2000 compliance
problems, and if

                                      125
<PAGE>

so, the nature of such difficulties. Ziff-Davis Inc. anticipates that such
inquiries will be completed by April 30, 1999.

  In addition, Ziff-Davis Inc. will develop contingency plans during the second
half of 1999 in order to compensate for any disruption or downtime that could
result from a Year 2000 compliance problem. Ziff-Davis Inc. plans to replace IT
and non-IT systems that it determines are not Year 2000 compliant prior to
October 1, 1999 in order to minimize any risk of a Year 2000 compliance
problem.

  Ziff-Davis Inc. has incurred remediation costs associated with its Year 2000
readiness efforts. These remediation costs have been incurred in connection
with replacement of systems and hardware, modification of software and
consulting costs related to Year 2000 solution providers. The costs to address
Year 2000 issues which have been included in the general and administrative
expenses of Ziff-Davis Inc. have not been tracked separately and are therefore
not determinable. However, management believes these expenses have been
substitutive rather than incremental to the recurring level of general and
administrative expenses. Total capitalized costs incurred in the replacement of
systems in connection with Ziff-Davis Inc.'s Year 2000 readiness efforts as of
December 31, 1997 and 1998 were $1,692,000 and $3,837,000, respectively. Ziff-
Davis Inc. estimates that it will incur an additional $3,815,000 during 1999
related to its Year 2000 readiness efforts.

  Ziff-Davis Inc. expects to complete testing and replacement of critical
systems by the beginning of the fourth quarter of 1999. Ziff-Davis Inc.'s
estimate of its most reasonably likely "worst case scenario" would be the
failure of its internal applications and systems that process and store certain
information and data. Ziff-Davis Inc. would resolve the failure of such
applications and systems one by one and management of Ziff-Davis Inc. does not
believe that the impact on its critical systems would be material. However, if
Ziff-Davis Inc. or any subscribers, advertisers, licensors, vendors or other
third parties on whom it relies experiences a Year 2000 compliance problem,
this could have a material adverse effect on Ziff-Davis Inc.'s profit and
liquidity.

Recently Issued Accounting Pronouncements

  SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities,
issued in June 1998, establishes accounting and reporting standards for
derivative instruments and for hedging activities and is effective for all
fiscal quarters of fiscal years beginning after June 15, 1999. Ziff-Davis Inc.
does not expect the adoption of SFAS No. 133 to have a material impact on Ziff-
Davis Inc.'s results of operations.

  Ziff-Davis Inc. expects to adopt this statement beginning with its 2000
financial statements.

Option Grants and Exercises in 1998

Composition of the Board of Directors

  The board of directors currently consists of nine members. The board of
directors intends to nominate for election one additional "independent
director" within the meaning of the regulations of the NYSE. Our directors are
currently elected annually by the stockholders to serve during the ensuing year
or until their respective successors are duly elected and qualified. The board
of directors is divided into three classes each of whose members serves for a
staggered three-year term. Upon the expiration of the term of a class of
directors, directors in such class are elected for three-year terms at the
annual meeting of stockholders in the year in which such term expires. See
"Description of Capital Stock--Certain Other Provisions of the Amended and
Restated Charter and By-laws".

Committees of the Board of Directors; Compensation Committee Interlocks and
Insider Participation

  The board of directors currently has two committees: an audit committee and a
compensation committee. The audit committee currently consists of Messrs.
Lazarus and Yang. The compensation committee currently consists of Messrs.
Fisher, Lazarus and Yang.

                                      134
<PAGE>

  Our audit committee reviews and recommends to the board of directors, as it
deems necessary, our internal accounting and financial controls and the
accounting principles and auditing practices and procedures to be employed in
preparation and review of our financial statements. Our audit committee makes
recommendations to the board of directors concerning the engagement of
independent public accountants and the scope of the audit to be undertaken by
such accountants. PricewaterhouseCoopers LLP presently serves as our
independent accountants.

  Our compensation committee reviews and, as it deems appropriate, recommends
to the board of directors 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 compensation
committee also advises and consults with the officers of Ziff-Davis Inc. as may
be requested regarding managerial personnel policies. The compensation
committee will have such additional powers and be granted additional authority
as may be conferred upon it from time to time by the board of directors.

  Each of Messrs. Fisher, Lazarus and Yang is independent of management. Mr.
Fisher is the Vice Chairman of SOFTBANK America, our majority stockholder, and
Mr. Yang is a co-founder and Chief Yahoo of Yahoo! Inc. Mr. Hippeau, Ziff-Davis
Inc.'s chairman and chief executive officer, is a director and serves on the
compensation committee of Yahoo! Inc. For information concerning certain
relationships between Ziff-Davis Inc. and SOFTBANK America and its officers or
between Ziff-Davis Inc. and Yahoo! Inc., see "Certain Relationships With Our
Majority Stockholders And Related Transactions".

Compensation of Directors

  Directors who are not executive officers or employees of Ziff-Davis Inc. or
SOFTBANK Corp., SOFTBANK Holdings or SOFTBANK America 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.

  Directors of Ziff-Davis Inc. who are not employees of Ziff-Davis Inc.,
SOFTBANK Corp., SOFTBANK Holdings or SOFTBANK America will automatically
participate in the 1998 Non-Employee Directors' Stock Option Plan (the "Non-
Employee Directors' Plan"). The Non-Employee Directors' Plan is administered by
the compensation committee and is summarized below.

 Shares Reserved For Issuance

  The aggregate number of shares reserved for issuance under the Non-Employee
Directors' Plan is 300,000 shares of common stock, regardless of series,
subject to adjustment by the compensation committee in the event of any change
in the outstanding shares of common stock by reason of any:

  . stock dividend or split,

  . recapitalization,

                                      135
<PAGE>

  . merger,

  . consolidation,

  . spinoff,

  . combination,

  . exchange of shares

  .  other corporate change or

  . distributions to common stockholders other than regular cash dividends.

  Shares subject to or underlying an option that expires unexercised, or is
forfeited, terminated or canceled, or is paid in cash in lieu of common stock
and shares that are tendered to pay for the exercise of an option will
thereafter be available for grant under the Non-Employee Directors' Plan.

  Pursuant to the Non-Employee Directors' Plan, each non-employee director will
receive upon election as a member of the board of directors an initial grant of
stock options to purchase 15,000 shares of common stock which shall be composed
of shares of ZD stock or following an initial public offering of the ZDNet
stock, shares of ZD stock and shares of ZDNet stock in such proportion as
determined by the committee administering the Non-Employee Directors' Plan;
provided that:

  . each non-employee director who is on the board of directors on the date
    of the initial public offering of ZDNet stock will receive a grant of
    stock options to purchase 25,000 shares of ZDNet stock on the date of
    such offering at the initial public offering price which will vest and
    become exercisable with respect to 25% of the shares on December 31 of
    the year in which the consummation of the offering occurs, and an
    additional 6.25% of the shares at the end of each three-month period
    thereafter and

  . each non-employee director who was on the board of directors on the date
    of the initial public offering of Ziff-Davis Inc.'s common stock in April
    1998 received such initial grant on the date of such initial public
    offering.

  On the date of each annual shareholders meeting thereafter, each non-employee
director shall automatically receive an annual grant of stock options to
purchase 7,500 additional shares of common stock which shall be composed of
shares of ZD stock or following an initial public offering of the ZDNet stock,
shares of ZD stock and shares of ZDNet stock in such proportion as determined
by the committee administering the Non-Employee Directors' Plan.

  Except as otherwise provided with respect to the initial grant of options to
purchase 25,000 shares of ZDNet stock, and unless otherwise determined by the
committee administering the Non-Employee Directors' Plan, the terms of each
stock option granted to a non-employee director will provide that:

  . the option price will 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,

  . such option will be exercisable for a period of 10 years following the
    date of grant,

                                      136
<PAGE>

  . such option will vest and become exercisable in five equal installments
    beginning on the first anniversary of the date of grant and

  . upon ceasing to be a non-employee director, such option will terminate
    except with respect to any portion of such option then exercisable, which
    portion will remain exercisable for a period of:

   . 90 days, if the termination as director resulted from any reason other
     than death, disability or cause or

   . 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 will immediately terminate and no longer be exercisable to any
extent; provided, further, that in no event will any such option remain
exercisable past the remainder of its scheduled ten-year term.

 Change In Control

  Upon a change in control of Ziff-Davis Inc., each outstanding option will
fully vest and become immediately exercisable in full. In addition, the
compensation committee may provide in its sole discretion that upon a change in
control of Ziff-Davis Inc., each non-employee director will 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:

  .  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

  .  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 compensation committee at such time.

 Amendment And Termination

  The board of directors may amend, suspend or terminate the Non-Employee
Directors' Plan or any portion thereof at any time; provided that, no amendment
shall be made:

  .  without stockholder approval if such approval is necessary in order for
     the Non-Employee Directors' Plan to comply with any applicable law,
     regulation or stock exchange rule and

  .  except in the case of a change in control of Ziff-Davis Inc., that would
     adversely affect the rights of any non-employee director under any
     outstanding option without such non-employee director's written consent.

Incentive Compensation Plan

 General

  Ziff-Davis Inc. has adopted the 1998 Incentive Compensation Plan (the
"Incentive Plan") to provide long-term incentives for its key employees and
enhance stockholder value, the principal terms and conditions of which are set
forth below.

                                      137
<PAGE>

  The Incentive Plan will be administered by the board of directors or the
incentive compensation plan committee which:

  .  selects the participants and determines the type of awards and the
     number of shares or share units subject to awards and

  .  interprets the Incentive Plan and makes all other determinations
     necessary or advisable for its administration.

  All employees and consultants of Ziff-Davis Inc. and our affiliates who have
demonstrated significant management potential or the capacity for contributing
substantially to the successful performance of Ziff-Davis Inc. and our
affiliates, are eligible to be participants in the Incentive Plan. Awards may
consist of stock awards, stock options (either incentive stock options within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, 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.

  Under the Incentive Plan up to 23,000,000 shares of common stock, regardless
of series, will be available for issuance out of authorized and unissued shares
or treasury shares, as the incentive compensation plan committee may from time
to time determine, and up to an additional 327,500 shares will be available out
of outstanding shares of common stock to be supplied by Ziff-Davis Inc.'s
majority stockholder in respect of awards of stock options granted to certain
participants in connection with the cancellation of corresponding options to
purchase stock of SOFTBANK Corp. For additional information concerning options
granted in connection with the cancellation of corresponding options to
purchase stock of SOFTBANK Corp., see "Certain Relationships With Our Majority
Stockholders And Related Transactions" and the Financial Statements for each of
Ziff-Davis Inc. and ZD.

In the event of any change in the outstanding shares by reason of any:

  . stock dividend or split,

  .  recapitalization,

  .  merger,

  .  consolidation,

  .  spin-off,

  .  combination,

  .  exchange of shares,

  .  other corporate change or

  .  distributions to common stockholders other than regular cash dividends

the incentive compensation plan 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 Incentive
Plan and to outstanding awards. Shares

                                      138
<PAGE>

subject to an award that expires unexercised or is forfeited, terminated,
canceled or paid in cash in lieu of common stock, and shares tendered to pay
for the exercise of a stock option, will thereafter again be available for
grant under the Incentive Plan.

  Each award under the Incentive Plan will be evidenced by an agreement setting
forth the terms and conditions, as determined by the incentive compensation
plan committee, which apply to such award. In the sole discretion of the
incentive compensation plan committee, a participant may be permitted to defer
the receipt of cash or common stock otherwise deliverable under any award.

 Stock Options

  The incentive compensation plan committee will establish the option price at
the time each stock option is granted, which price will generally not be less
than 100% of the fair market value of the common stock on the date of grant,
unless otherwise specifically determined by the incentive compensation plan
committee. Stock options will vest and become exercisable at a rate determined
by the incentive compensation plan committee, and will remain exercisable for
such period as specified by the incentive compensation plan
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;
provided that, solely for the 1998 calendar year, no individual employee may
receive grants of options with respect to more than 2,600,000 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 incentive compensation plan
committee deems appropriate.

 Stock Appreciation Rights

  Stock appreciation rights, also known as SARs, may be granted in tandem with
a stock option or may be unrelated to a stock option. SARs will vest and become
exercisable at a rate determined by the incentive compensation plan committee,
and will remain exercisable for such period as specified by the incentive
compensation plan committee. SARs entitle holders to receive from Ziff-Davis
Inc. 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 of a share
of common stock on the date of grant. The incentive compensation plan committee
will 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.

                                      139

 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 conditions and the length of the performance
period will be determined by the incentive compensation plan committee but in
no event may a performance period be less than one year. The incentive
compensation plan committee will 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 incentive compensation plan committee determines otherwise, awards
of performance shares to a covered employee will be subject to performance
conditions based on the achievement by Ziff-Davis Inc. of target levels of
items such as consolidated net income, return on stockholders' equity, return
on net assets or share price performance. For purposes of the Incentive Plan, a
"covered employee" generally includes any employee that would be a covered
employee within the meaning of Section 162(m) of the Code and any other
employee of Ziff-Davis Inc. 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 incentive compensation plan
committee at time of grant, except that each restriction period will not be
less than 12 months. During the restricted period, shares of restricted stock
may not be:

  .sold,

  .assigned,

  .transferred,

  .otherwise disposed of,

  . pledged or hypothecated as collateral for a loan or as security for the
    performance of any obligation

  . or for any other purpose as the incentive compensation plan committee
    determines.

The incentive compensation plan committee will 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 Incentive Plan in the form of actual
shares of common

                                      140
<PAGE>

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, will immediately vest in such participant.

 Change In Control

  In the event of a Change in Control (as defined below):

  . all stock options will be fully vested and exercisable in full,

  . all SARs which have not been granted in tandem with stock options will
    become exercisable in full,

  . 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,

  . all performance shares will be deemed to be earned at target level and

  . all performance shares granted in the form of share units will be paid in
    cash.

  For purposes of the Incentive Plan, "Change in Control" is generally defined
as:

  (1) a change in the majority of the board of directors except upon consent
      of the previous board of directors,

  (2) certain mergers, consolidations or similar corporate transactions in
      which Ziff-Davis Inc. is not the surviving corporation or entity or

  (3) a plan of complete liquidation or dissolution of Ziff-Davis Inc. or a
      sale of all or substantially all of Ziff-Davis Inc.'s assets that is
      approved by the stockholders of Ziff-Davis Inc.;

provided that, a Change in Control will not be deemed to occur under clause (2)
if SOFTBANK Corp., directly or indirectly, is the beneficial owner of more than
25% of the Ziff-Davis Inc.'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 Incentive Plan or
any portion thereof at any time; provided that:

  . no amendment will be made without stockholder approval (including an
    increase in the number of shares reserved for issuance under the
    Incentive Plan) if such approval is necessary in order for the Incentive
    Plan to comply with any applicable law, regulations or stock exchange
    rule and

  . 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.

                                      141
<PAGE>

 Effective Date

  The Incentive Plan has a term of 10 years from February 13, 1998, subject to
earlier termination.

 Repricing

  On September 23, 1998, the incentive compensation plan committee authorized
the amendment of options granted under the Incentive Plan prior to that date
including those granted on June 24, 1998. Pursuant to such amendment, the
exercise price of such options was reduced from $16.00 to $6.00 (the closing
price of our common stock on September 23, 1998), but the options will not vest
until three months after the dates on which the options were originally to
become vested.

Employee Stock Purchase Plan

 General

  Ziff-Davis Inc. has adopted the 1998 Employee Stock Purchase Plan (the "Stock
Purchase Plan"), the principal terms and conditions of which are set forth
below.

  The Stock Purchase Plan is intended to meet the applicable requirements of
Section 423 of the Internal Revenue Code and will be administered by a
committee appointed by the board of directors.

 Shares Subject To Plan

  The aggregate maximum number of shares of common stock, regardless of series,
purchasable under the Stock Purchase Plan is 2,500,000, subject to adjustment
by the committee in its sole discretion in the event of any change in the
outstanding shares of common stock by reason of any:

  .stock dividend or split,

  . recapitalization,

  . merger,

  . consolidation,

  . spin-off,

  . combination,

  . exchange of shares,

  . other corporate change or

  . distribution to common stockholders other than regular cash dividends.

Upon the dissolution or liquidation of Ziff-Davis Inc., or upon a
reorganization, merger or consolidation of Ziff-Davis Inc., as a result of
which Ziff-Davis Inc. is not the surviving corporation, or upon a sale of
substantially all of Ziff-Davis Inc.'s assets or a sale or

                                      142
<PAGE>

distribution of a subsidiary of Ziff-Davis Inc., 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.

 Option To Purchase

  Under the Stock Purchase Plan, all full-time and certain part-time employees
of Ziff-Davis Inc. 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 price at which shares of common stock will be purchased at the end of
each purchase period will be the lesser of:

  . 85% of the fair market value of a share of common stock on the first
    business day of such purchase period or

  . 85% of the fair market value on the last business day of such 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 of directors may at any time terminate or amend the Stock Purchase
Plan. No such termination will 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 will be effective
unless approved by the stockholders of Ziff-Davis Inc. if such stockholder
approval of such amendment is required to comply with any law, regulation or
stock exchange rule.

Softbank Executive Stock Option Plans

  The SOFTBANK Group Executive Stock Option 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. 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
(Yen)4,000 per share, the market price of SOFTBANK Corp.'s common stock on that
date.

              CERTAIN RELATIONSHIPS WITH OUR MAJORITY STOCKHOLDERS
                            AND RELATED TRANSACTIONS

Arrangements Between Majority Stockholders and Ziff-Davis Inc.

  We have entered into certain agreements with Softbank governing ongoing
business relationships. It is possible that the terms of these agreements are
not those that would result from an arm's-length dealing among unrelated
parties.

  In July 1997, we entered into a license agreement with SOFTBANK Corp. for
SOFTBANK Corp. to operate a localized edition of ZDNet in Japan. Pursuant to
the agreement, we paid SOFTBANK Corp. $146,000 on July 9, 1998, in connection
with the 1997 launch of the localized edition of ZDNet.

  In April 1998, we entered into a master license agreement with SOFTBANK Corp.
for Softbank to produce and distribute ZD publications in Japan. Pursuant to
the agreement, SOFTBANK Corp. incurred royalties equal to approximately
$709,000 in 1998.

  In April 1998, we entered into a series of agreements with Softbank,
including:

  .a trademark license agreement,

  .a technical assistance agreement and

  .an accounting and administrative agreement,

pursuant to which Softbank produces ZD Events trade shows and conferences in
Japan and we provide management and other services for those trade shows and
conferences. Total revenue earned by us from such trade shows and conferences
agreements was approximately 50% of the pre-tax income generated by such trade
shows and conferences, which was $787,000 in 1998.

  In May 1998, we entered into an undertaking with SOFTBANK Corp. whereby
SOFTBANK Corp., on behalf of it and its affiliates, agreed that as long as it
owns 40% of the voting power in our stock and can elect a majority of the board
of directors, it will not expand its operations outside Japan in competition
with us without our prior approval which involve:

  . publishing information on computing and Internet-related technology
    through the media of print, CD-Rom/DVD, Internet and television or

  . producing trade shows, conferences, exhibitions and similar events
    primarily related to computing and Internet-related technology.

This undertaking does not preclude investments by venture capital funds managed
by Softbank which invest in, among other things, computer and Internet-related
companies. These funds may be able to co-invest with or compete with us with
respect to new investments. In addition, Softbank may also develop new funds in
the future which may compete with us for investment opportunities. We have
agreed not to compete with Softbank in Japan without the prior approval of
SOFTBANK Corp.'s board of directors and

                                      146
<PAGE>

have given Softbank the continuing right to license all of our products and
services in Japan. See "Risk Factors--Other Ziff-Davis Inc. Risks--Ziff-Davis
Inc. Is Controlled by Its Principal Stockholders. This Creates Potential
Conflicts Of Interest".

  We entered into a registration rights agreement, dated as of April 1, 1998,
in connection with the initial public offering of our existing common stock.
The agreement gives Softbank the right to require us to register any or all of
our existing common stock held by it in a public offering pursuant to the
Securities Act, and to "piggyback" or include its shares of our existing common
stock in any registration of our existing common stock made by us.

The Reorganization

  Prior to our initial public offering in April 1998, our businesses were
conducted through various indirect subsidiaries of SOFTBANK Corp. and were
acquired through a series of acquisitions and internal reorganizations
undertaken by Softbank as follows:

  . Softbank acquired the computer technology publishing operations of Ziff-
    Davis Publishing Company, which was renamed Ziff-Davis Inc. and
    subsequently named ZD Inc., in February 1996 for $1.8 billion in cash,

  . Softbank acquired the SB COMDEX computer-related trade show operations,
    which was renamed SOFTBANK COMDEX Inc., in April 1995 for $803 million in
    cash, and

  . Softbank acquired the computer and network-related trade show operations
    of Ziff-Davis Exposition and Conference Company, which was subsequently
    renamed SOFTBANK Forums Inc., in December 1994 for $127 million in cash.

  Concurrently with the ZD Publishing 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"). The MAC Assets
consisted of certain publications, international trade shows and the ZDNet
business, most of which were still under development. The MAC Assets and
related operations were managed by ZD Inc. and ZD Events after their
acquisition by MAC and were acquired by us for approximately $370 million in
May 1998.

  In October 1997, Softbank combined the businesses of ZD Inc., SOFTBANK COMDEX
and SOFTBANK Forums. SOFTBANK Forums and SOFTBANK COMDEX were merged as of
December 31, 1997, with the surviving corporation named ZD COMDEX and Forums
Inc., which is now ZD Events Inc.

  The amount of intercompany indebtedness converted to equity consisted of:

  . the obligations due to Softbank as of December 31, 1997 other than those
    repaid with borrowings under our credit facility and the proceeds of our
    offering of senior subordinated notes and

  . a $94.2 million note which matures on February 28, 2009.


                                      147
<PAGE>

At an initial public offering price of $15.50 per share, the value of the
capitalized intercompany indebtedness was equal to 59.9 million shares of our
existing common stock.

  In addition, we exchanged 580,645 shares of our existing common stock, valued
at the initial public offering price, and $100,000 in funds for approximately
$9.1 million of fixed assets from Kingston Technology Company. Kingston
Technology is a subsidiary of SOFTBANK Kingston Inc., which in turn is a wholly
owned subsidiary of SOFTBANK Holdings. We subsequently leased back the assets
we received in this exchange to Kingston Technology and on May 4, 1998,
Kingston Technology transferred the shares of our existing common stock to
SOFTBANK Kingston.

  At the time of the initial public offering of our existing common stock and
senior subordinated notes in April 1998, we reorganized our structure so that:

  . All of the stock of the corporations owning our publishing and events
    businesses, ZD Inc. and ZD Events, was contributed to Ziff-Davis Inc. in
    exchange for approximately 72% of our existing common stock.

  . We purchased certain operations owned by MAC but managed by our
    publishing business, including certain publications, international trade
    shows and ZDNet.

  . We entered into a $1.35 billion credit facility with a group of financial
    institutions and borrowed $1.25 billion under that facility.

  . Approximately $909 million of our obligations to SOFTBANK Corp. were
    converted to equity.

  . We repaid approximately $1.6 billion of our obligations to Softbank.

Certain Related Party Transactions

  We are a member of a group of companies affiliated through common ownership
under SOFTBANK Corp. Accordingly, we have had various transactions and have
various relationships with members of the group, including SOFTBANK Corp.'s
wholly owned U.S. subsidiary, SOFTBANK Holdings. 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. At that time,
SOFTBANK Forums and Son Kosan Inc. entered into a management agreement pursuant
to which SOFTBANK Forums agreed to provide management services with respect to
certain Son Kosan operations in Japan, France and Germany. SOFTBANK Forums
earned approximately $0.8 million, $1.7 million and $2.6 million for such
services for the years ended December 31, 1995, 1996 and 1997 respectively. Son
Kosan's trade show assets were sold to SOFTBANK Forums for $10 million in
January 1997 and certain of MAC's trade show assets were contributed to ZD
Events as part of the reorganization.

                                      148
<PAGE>

  In February 1996, as part of the acquisition of ZD Publishing, MAC purchased
certain publishing assets for $302 million in cash. At that time, we entered
into a management agreement with MAC pursuant to which we agreed to provide
management services with respect to the purchased assets. We earned
approximately $2 million for such services for each of the years ended
December 31, 1996 and 1997 and $667,000 in 1998, respectively. Of these assets,
a portion was transferred to us for $100 million as of October 31, 1997 and the
balance was sold to us for $270 million concurrently with our initial public
offering in May 1998. The purchase price for the assets sold to ZD Inc. was not
more than fair market value as determined by an independent appraiser.

  We entered into a series of license and syndication agreements with Softbank
pursuant to which Softbank was granted the license to publish or use in Japan
certain materials from certain publications, including PC Week, Computer
Shopper, PC/Computing, Computer Gaming World and PC Magazine. We earned
approximately $963,948 and $1,817,986 in connection therewith for the years
ended December 31, 1996 and 1997, respectively. Such agreements were combined
into the master license agreement described above.

  We have 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 totaled $68.2 million, $71.6 million and
$55.2 million in 1996, 1997 and 1998, respectively. The remaining outstanding
amount as of December 31, 1997 of $42.6 million was reimbursed in May 1998, in
connection with our reorganization.

  For information concerning the development of ZDTV and our purchase from an
affiliate, see "Ziff-Davis Inc. Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources--ZDTV".

  During 1997 and 1998, we entered into an operating lease with GE Capital
Corp. for certain television production equipment that we subleased to ZDTV on
similar terms. The total amount of leased equipment does not exceed $10
million.

  During 1996, 1997 and 1998, we recorded revenue of approximately $.9 million,
$2.7 million and $3.1 million, respectively, from sales of advertising space
and trade show services to Kingston Technology, an 80%-owned Softbank
partnership. These services were provided under terms consistent with those
provided to unaffiliated customers. See Note 10 to the Notes to the
Consolidated Financial Statements of Ziff-Davis Inc. appearing in this
prospectus. Concurrently with the initial public offering of our existing
common stock, we entered into a sale-leaseback transaction with Kingston
Technology.

  In 1997, we had an arrangement with SOFTBANK Interactive, a 65.3%-owned
Softbank subsidiary, for it to be ZDNet's advertising sales representative. We
paid SOFTBANK Interactive approximately $0.6 million and $1.8 million in
commissions for the years ended December 31, 1996 and 1997, respectively.
Effective December 31, 1997, SOFTBANK Interactive was acquired by an unrelated
third party and we terminated our representation agreement with SOFTBANK
Interactive. See Note 10 to the Notes to the Consolidated Financial Statements
of Ziff-Davis Inc. appearing in this prospectus.

                                      149
<PAGE>

  During 1996, 1997 and 1998, we were party to a joint venture agreement with
Softbank pursuant to which we managed all ZD Events trade shows and conferences
conducted outside the U.S. We earned approximately $3.4 million, $4.0 million
and $1.1 million for such services for the years ended December 31, 1996, 1997
and 1998, respectively.

  During 1996, 1997 and 1998, we incurred $2 million, approximately $1.6
million and $0.3 million, respectively, in advertising expenses with Yahoo!
Inc., which is approximately 30.1% owned by Softbank. Mr. Yang, one of our
directors, is a co-founder and Chief Yahoo, and Mr. Hippeau, our Chief
Executive Officer, is a director of, Yahoo! Inc.

  During 1996 to 1997, we 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 Exposition and Conference
Company, SB COMDEX and ZD Publishing. In the course of our reorganization and
initial public offering, all but $83.1 million of these notes were either
repaid or converted into equity. See Notes 2 and 12 to the Notes to the
Consolidated Financial Statements of Ziff-Davis Inc. appearing in this
prospectus.

  As part of the acquisition by our former owner in 1994, we 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, under such arrangements we paid approximately $29.7 million
to Mr. Hippeau, our Chairman and CEO and one of our directors, and
approximately $1.0 million to Mr. Sheer, our Chief Internet Strategist. See
Note 12 to the Notes to the Consolidated Financial Statements of Ziff-Davis
Inc. appearing in this prospectus.

  Prior to the initial public offering of our existing common stock, we
participated in the Softbank cash management program for its U.S. operations.
Under this program we periodically transferred excess cash to SOFTBANK Holdings
and in turn received cash advances from SOFTBANK Holdings to fund our short-
term working capital requirements. Interest was accrued based on the net
balance outstanding at the end of each month. Interest income was earned at the
30-day LIBOR rate. Interest expense was incurred at such rate plus .50%. As of
December 31, 1996 and 1997, such net cash transfers from us to SOFTBANK
Holdings amounted to $41.3 million and $76.5 million, respectively. We have not
participated in this program since our initial public offering. See Note 12 to
the Notes to the Consolidated Financial Statements of Ziff-Davis Inc.

  During 1997, we were a guarantor under SOFTBANK Holdings' $150 million loan
agreement with The Bank of New York. As of December 31, 1997, $102.5 million
was outstanding under this agreement, bearing interest at a weighted average
rate of 6.5% per year. In March, 1998 this agreement was amended and restated
to increase the loan amount to $450 million. Under the amended agreement, we
were a guarantor under SOFTBANK Holdings' $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. Concurrently with
the initial public offering of our existing common stock, we repaid obligations
due to SOFTBANK Holdings and SOFTBANK Holdings used a portion of such proceeds
to prepay the loans under the credit facility and the guarantees were
terminated.

                                      150

  SOFTBANK Holdings and its subsidiary, SOFTBANK Holdings Delaware, agreed to
act as guarantors for payments under our lease for our new headquarters located
at 28 East 28th Street, New York, New York. In addition, the various
intercompany loans from SOFTBANK Holdings Delaware to us were subordinated to
the lease agreement. In accordance with the terms of these agreements, those
arrangements were terminated at the time of our reorganization.

  From 1997 to date, we have participated in a global insurance program
implemented by SOFTBANK Holdings. The total amount of insurance expenses
allocated to us for the period from August 1, 1997 to July 30, 1999 does not
exceed $1.4 million.

  On May 14, 1998, SOFTBANK Kingston sold 50,000 shares of our existing common
stock to an unrelated third party.

  On May 28, 1998, the U.S. underwriters for our initial public offering
exercised their option to purchase two million additional shares of Ziff-Davis
Inc. common stock to cover over-allotments. We purchased the additional shares
from SOFTBANK Holdings resulting in no change to the total number of shares
outstanding.

  On December 29, 1998, SOFTBANK Kingston sold 30,000 shares of Ziff-Davis Inc.
common stock to an unrelated third party. On December 31, 1998, SOFTBANK
Holdings contributed 71,619,355 shares of Ziff-Davis Inc. common stock to
SOFTBANK America Inc., an affiliate of SOFTBANK Corp. On March 12, 1999,
SOFTBANK Kingston sold 500,000 shares of Ziff-Davis Inc. common stock to an
unrelated third party.

  On January 29, 1999, Ziff-Davis Inc. granted options to a number of employees
in connection with the cancellation of corresponding options to purchase stock
of SOFTBANK Corp. In connection with these grants, an affiliate of SOFTBANK
Corp. has agreed with Ziff-Davis Inc. that, if and when any of these options
are exercised, (1) that affiliate will cause the shares of Ziff-Davis Inc.
common stock issuable upon such exercise to be supplied to Ziff-Davis and (2)
Ziff-Davis will deliver to that affiliate or its designee the exercise price
paid upon such exercise. Thus, the exercise of these options will not increase
the number of shares of Ziff-Davis Inc. common stock outstanding or Ziff-Davis
Inc.'s stockholders' equity. However, Ziff-Davis Inc. expects to recognize
compensation expense for accounting purposes of approximately $ 3,018,000
million over three years as a result of these grants. An affiliate of SOFTBANK
Corp. has agreed to reimburse Ziff-Davis Inc. for any compensation expense
recognized by it for accounting purposes as a result of such grants. Any such
reimbursement would likely not be treated as income for accounting purposes,
but would restore Ziff-Davis Inc.'s stockholders' equity to the level it would
have been in the absence of such expense. Each reimbursement will be credited
to ZD or ZDNet, as appropriate, to reflect the amount of expense appropriate to
ZD or ZDNet.

                CERTAIN CASH MANAGEMENT AND ALLOCATION POLICIES

  In order to prepare separate financial statements for ZD and ZDNet, Ziff-
Davis Inc. has allocated all of its consolidated assets, liabilities, revenue,
expenses and cash flow between ZD and ZDNet. In this prospectus, each of ZD and
ZDNet is sometimes called a group. Thus, the financial statements of ZD and
ZDNet, taken together, comprise all of the accounts included in the
corresponding consolidated financial statements of Ziff-Davis Inc.

  The financial statements of ZD and ZDNet reflect the application of certain
cash management and allocation policies adopted by the board of directors.
These policies are summarized below.

  The board of directors may, in its sole discretion, modify, rescind or add to
any of these policies, although it has no present intention to do so. The
decision of the board of directors to modify, rescind or add to any of these
policies would, however, be subject to the board of directors' general
fiduciary duties.

  Even though Ziff-Davis Inc. has allocated all of its consolidated assets,
liabilities, revenue, expenses and cash flow between ZD and ZDNet, holders of
ZDNet stock will continue to be common stockholders of Ziff-Davis Inc. and, as
such, will be subject to all risks associated with an investment in Ziff-Davis
Inc. and all of its businesses, assets and liabilities. See "Risk Factors--Risk
Factors Relating To ZDNet Stock--Holders Of ZDNet Stock Will Be Common
Stockholders Of Ziff-Davis Inc. And Will Be Subject To Risks Associated With An
Investment In Ziff-Davis Inc. As A Whole".

Treasury Activities

  Ziff-Davis Inc. manages most treasury activities on a centralized,
consolidated basis. These activities include the investment of surplus cash,
the issuance, repayment and repurchase of short-term and long-term debt, and
the issuance and repurchase of common stock and preferred stock. Each group
generally remits its cash receipts, other than receipts of foreign operations
or operations that are not wholly owned, to Ziff-Davis Inc., and Ziff-Davis
Inc. generally funds each group's cash disbursements, other than disbursements
of foreign operations or operations that are not wholly owned, on a daily
basis.

  In the historical financial statements of ZD and ZDNet:

    . all external debt and equity transactions, and the proceeds thereof,
      were attributed to ZD,

    . whenever ZDNet held cash, other than cash of ZDNet's foreign
      operations or of ZDNet's operations that are not wholly owned, that
      cash was transferred to ZD and accounted for as a return of capital,
      i.e., as a reduction in ZDNet's division equity and ZD's retained
      interest in ZDNet and

    . whenever ZDNet had a cash need, other than cash needs of ZDNet's
      foreign operations or of ZDNet's operations that are not wholly
      owned, that cash need was funded by ZD and accounted for as a capital
      contribution, i.e., as an increase in ZDNet's division equity and
      ZD's retained interest in ZDNet.


                                      154
<PAGE>

Ziff-Davis Inc. intends to continue these practices until ZDNet stock is first
issued. Accordingly, no interest expense has been or will be reflected in the
financial statements of ZDNet, and no interest income from ZDNet has been or
will be reflected in the financial statements of ZD, for any period prior to
the date on which ZDNet stock is first issued.

  After the date on which ZDNet stock is first issued:

    (1) Ziff-Davis Inc. will attribute each future incurrence or issuance of
  external debt or preferred stock and the proceeds thereof to ZD, unless the
  board of directors determines otherwise. The board of directors may, but is
  not required to, attribute an incurrence or issuance of debt or preferred
  stock, and the proceeds thereof, to ZDNet to the extent that Ziff-Davis
  Inc. incurs or issues the debt or preferred stock for the benefit of ZDNet.

    (2) Ziff-Davis Inc. will attribute each future issuance of ZD stock, and
  the proceeds thereof, to ZD. Ziff-Davis Inc. may attribute any future
  issuance of ZDNet stock and the proceeds thereof:

    . to ZD in respect of its retained interest in ZDNet, in a manner
      analogous to a secondary offering of common stock of a subsidiary
      owned by a corporate parent, or

    . to ZDNet, in a manner analogous to a primary offering of common
      stock.

  Dividends on and repurchases of ZD stock will be charged against ZD, and
  dividends on and repurchases of ZDNet stock will be charged against ZDNet.
  In addition, at the time of any dividend on ZDNet stock, Ziff-Davis Inc.
  will credit to ZD, and charge against ZDNet, a corresponding amount in
  respect of ZD's retained interest in ZDNet. See "--Description of Capital
  Stock--ZD's Retained Interest in ZDNet".

    (3) Whenever ZDNet holds cash, other than cash of ZDNet's foreign
  operations or cash of ZDNet's operations that are not wholly owned, ZDNet
  will normally transfer that cash to ZD. Conversely, whenever ZDNet has a
  cash need, other than cash needs of ZDNet's foreign operations or cash
  needs of ZDNet's operations that are not wholly owned, ZD will normally
  fund that cash need. However, the board of directors will determine, in its
  sole discretion, whether to provide any particular funds to either ZD or
  ZDNet and will not be obligated to do so.

    (4) Ziff-Davis Inc. will account for all cash transfers from one group to
  or for the account of the other group, other than transfers in return for
  assets or services rendered or transfers in respect of ZD's retained
  interest that correspond to dividends paid on ZDNet stock, as inter-group
  revolving credit advances unless:

    . the board of directors determines that a given transfer or type of
      transfer should be accounted for as a long-term loan,

    . the board of directors determines that a given transfer or type of
      transfer should be accounted for as a capital contribution increasing
      ZD's retained interest in ZDNet or

    . the board of directors determines that a given transfer or type of
      transfer should be accounted for as a return of capital reducing ZD's
      retained interest in ZDNet.


                                      155
<PAGE>

  There are no specific criteria to determine when Ziff-Davis Inc. will
  account for a cash transfer as a long-term loan, a capital contribution or
  a return of capital rather than an inter-group revolving credit advance.
  The board of directors would make such a determination in the exercise of
  its business judgment at the time of such transfer, or the first of such
  type of transfer, based upon all relevant circumstances. Factors the board
  of directors would consider include:

    . the current and projected capital structure of each group,

    . the relative levels of internally generated funds of each group,

    . the financing needs and objectives of the recipient group,

    . the investment objectives of the transferring group,

    . the availability, cost and time associated with alternative financing
      sources and

    . prevailing interest rates and general economic conditions.

    (5) Any cash transfer accounted for as an inter-group revolving credit
  advance will bear interest at the rate at which the board of directors, in
  its sole discretion, determines Ziff-Davis Inc. could borrow such funds on
  a revolving credit basis. Any cash transfer accounted for as a long-term
  loan will have interest rate, amortization, maturity, redemption and other
  terms that generally reflect the then prevailing terms on which the board
  of directors, in its sole discretion, determines Ziff-Davis Inc. could
  borrow such funds.

    (6) Any cash transfer from ZD to ZDNet or for ZDNet's account accounted
  for as a capital contribution will correspondingly increase ZDNet's
  division equity and ZD's retained interest in ZDNet. As a result, the
  number of shares of ZDNet stock that Ziff-Davis Inc. may issue for the
  account of ZD in respect of its retained interest (which we call the number
  of shares issuable with respect to ZD's retained interest in ZDNet) will
  increase by the amount of such capital contribution divided by the market
  value of ZDNet stock on the date of transfer.

    This increase in the number of shares issuable with respect to ZD's
  retained interest in ZDNet may also be expressed as follows:

                    Amount of Capital Contribution to ZDNet
                   -----------------------------------------
                 Market Value of ZDNet on the Date of Transfer

    (7) Any cash transfer from ZDNet to ZD, or for ZD's account, accounted
  for as a return of capital will correspondingly reduce ZDNet's division
  equity and ZD's retained interest in ZDNet. As a result, the number of
  shares issuable with respect to ZD's retained interest in ZDNet will
  decrease by the amount of such return of capital divided by the market
  value of ZDNet stock on the date of transfer.

    This decrease in the number of shares issuable with respect to ZD's
  retained interest in ZDNet may also be expressed as follows:

                      Amount of Return of Capital to ZDNet
                ----------------------------------------------
              Market Value of ZDNet stock on the Date of Transfer

Corporate General and Administrative Expenses

  Ziff-Davis Inc. allocates the cost of certain corporate general and
administrative services and shared services to the groups generally based on
utilization. These shared services include:

  .legal,

  .accounting (tax and financial),

  .information services,

  .telecommunications,

  .purchasing,

  .marketing,

  .intellectual property,

  .public relations,

  .corporate office and

  .travel expenses.

Where determinations based on utilization alone are impracticable, Ziff-Davis
Inc. uses other methods and criteria that management believes are fair to
provide a reasonable estimate of the cost attributable to each group.

Taxes

  Federal income taxes, which are determined on a consolidated basis, are
allocated to each group and reflected in their respective financial statements
in accordance with Ziff-Davis Inc.'s tax allocation policy. In general, this
policy provides that the consolidated tax provision and related tax payments or
refunds are allocated between the groups based principally upon the financial
income, taxable income, credits and other amounts directly related to the
respective groups. Tax benefits that cannot be used by the group generating
such attributes, but can be utilized on a consolidated basis, are allocated to
the group that generated such benefits. As a result, the allocated group
amounts of taxes payable or refundable are not necessarily comparable to those
that would have resulted if the groups had filed separate tax returns. State
income taxes generally are computed on a separate company basis.

Royalty Charges

  ZD charges ZDNet an annual fee for the use of various ZD brands and editorial
content. The current annual fee, which is reflected in ZDNet's financial
statements as part of its production and content costs and in ZD's financial
statements as a reduction in selling, general and administrative expenses, is
equal to 5% of the first $100 million of ZDNet's revenue for the year, 4% of
the next $50 million of ZDNet's revenue for that year and 3% of any incremental
revenue over $150 million for that year. The board of directors may, in its
sole discretion, at some point in the future change this fee as it deems
appropriate in light of the circumstances from time to time.

                          DESCRIPTION OF CAPITAL STOCK

   The following description is not complete and should be read with the
 restated charter, which we have filed as an exhibit to the registration
 statement of which this prospectus is a part.

General

  Our current certificate of incorporation authorizes us to issue 130 million
shares, consisting of 120 million shares of common stock, par value $.01 per
share, and 10 million shares of preferred stock, par value $.01 per share. Only
the preferred stock is currently issuable in series by the Board. As of March
23, 1999, we had approximately 103 million shares of common stock and no shares
of preferred stock issued and outstanding.

  Before the offering, we will file an amended and restated certificate of
incorporation which would further amend and restate our current certificate of
incorporation. This restated charter will:

  . Increase the number of authorized shares of common stock from 120 million
    to 210 million.

  . Authorize the board of directors to issue common stock in two series--
    Ziff-Davis Inc.--ZD Common Stock, which we refer to in this prospectus as
    ZD stock and Ziff-Davis Inc.--ZDNet Common Stock, which we refer to in
    this prospectus as ZDNet stock. Initially, we will designate 130 million
    shares as ZD stock and80 million shares as ZDNet stock.

    . We intend ZDNet stock to reflect the performance of ZDNet.

    . We intend ZD stock to reflect the performance of ZD.

    . We have allocated all of Ziff-Davis Inc.'s consolidated assets,
      liabilities, revenue, expenses and cash flow between ZD and ZDNet. In
      the future, we will publish combined financial statements of ZD and
      combined financial statements of ZDNet together with consolidated
      financial statements of Ziff-Davis Inc.

  . Re-classify each outstanding share of common stock into a share of ZD
    stock. The filing would not change the authorized preferred stock.

  The full definitions of the terms "ZD" and "ZDNet" are set forth under "--
Mandatory Dividend, Redemption or Exchange on Disposition of All or
Substantially All of the Assets of a Group" below.

  Before the time of the offering, the board of directors will designate the
initial number of shares issuable with respect to ZD's retained interest in
ZDNet. See "--ZD's Retained Interest in ZDNet" and "--Number of Shares Issuable
with Respect to ZD's Retained Interest in ZDNet" and our restated charter for
additional information about ZD's retained interest in ZDNet and the number of
shares issuable with respect to ZD's retained interest in ZDNet.

                                      158
<PAGE>

  The board of directors will have the authority to increase or decrease from
time to time the total number of authorized shares comprising either series of
common stock. However, the board of directors could not increase the number of
authorized shares of a series above a number which, when added to all of the
authorized shares of the other series of common stock, would exceed the total
authorized number of shares of common stock. Likewise, the board of directors
could not decrease the number of authorized shares of a series below the number
of shares of such series then outstanding.

  The board of directors will have the authority in its sole discretion to
issue authorized but unissued shares of common stock from time to time for any
proper corporate purpose. The board of directors will have the authority to do
so without stockholders approval, except as provided by Delaware law or the
rules and regulations of any securities exchange on which any series of
outstanding common stock may then be listed.

Dividends

  We currently intend to retain all of our earnings to finance operations,
repay our indebtedness and fund future growth. We do not expect to pay
dividends on ZD stock or ZDNet stock for the foreseeable future.

  Although our various debt instruments currently prohibit the payment of
dividends, and in any event, as stated above, we do not expect to pay any
dividends for the foreseeable future on any series of common stock, we will
otherwise be permitted to pay dividends on

  . ZD stock out of assets of Ziff-Davis Inc. legally available for the
    payment of dividends under Delaware law, but the total amounts paid as
    dividends on ZD stock cannot exceed the available dividend amount for ZD
    and

  . ZDNet stock out of the assets of Ziff-Davis Inc. legally available for
    the payment of dividends under Delaware law, and transfer corresponding
    amounts to ZD in respect of its retained interest in ZDNet. However, the
    total amounts paid as dividends on ZDNet stock and the corresponding
    amounts transferred to ZD in respect of its retained interest in ZDNet
    cannot exceed the available dividend amount for ZDNet.

  The available dividend amount for ZD at any time is the amount that would
then be legally available for the payment of dividends on ZD's common stock
under Delaware law if

  . ZD and ZDNet were each a separate Delaware corporation,

  . ZD had outstanding (a) a number of shares of common stock, par value
    $0.01 per share, equal to the number of shares of ZD stock that are then
    outstanding and (b) a number of shares of preferred stock, par value
    $0.01 per share, equal to the number of shares of preferred stock of
    Ziff-Davis Inc. that have been attributed to ZD and are then outstanding,

  . the assumptions about ZDNet set forth in the next sentence were true and

                                      159
<PAGE>

  . ZD owned a number of shares of ZDNet stock equal to the number of shares
    issuable with respect to ZD's retained interest in ZDNet.

Similarly, the available dividend amount for ZDNet at any time is the amount
that would then be legally available for the payment of dividends on ZDNet's
common stock under Delaware law if ZDNet were a separate Delaware corporation
having outstanding:

  . a number of shares of common stock, par value $0.01 per share, equal to
    the number of shares of ZDNet stock that are then outstanding plus the
    number of shares issuable with respect to ZD's retained interest in ZDNet
    and

  . a number of shares of preferred stock, par value $0.01 per share, equal
    to the number of shares of preferred stock of Ziff-Davis Inc. that have
    been attributed to ZDNet and are then outstanding.

  The amount legally available for the payment of dividends on common stock of
a corporation under Delaware law is generally limited to:

  . the total assets of the corporation less its total liabilities less

  . the aggregate par value of the outstanding shares of its common and
    preferred stock.

  However, if that amount is not greater than zero, the corporation may also
pay dividends out of the net profits for the corporation for the fiscal year in
which the dividend is declared and/or the preceding fiscal year. As mentioned
above, these restrictions will form the basis for calculating the available
dividend amounts for ZD and ZDNet. These restrictions will also form the basis
for calculating the aggregate amount of dividends that Ziff-Davis Inc. as a
whole can pay on its common stock, regardless of series. Thus, net losses of
either group, and any dividends and distributions on, or repurchases of, either
series of common stock, will reduce the assets legally available for dividends
on both series of common stock.

  Subject to the foregoing limitations and to any other limitations set forth
in any future series of preferred stock or in any agreements binding on Ziff-
Davis Inc. from time to time, we have the right to pay dividends on both, one
or neither series of common stock in equal or unequal amounts, notwithstanding
the performance of either group, the amount of assets available for dividends
on either series, the amount of prior dividends paid on either series, the
respective voting rights of each series or any other factor.

  At the time of any dividend on the outstanding shares of ZDNet stock,
including any dividend required as a result of a disposition of all or
substantially all of the assets of ZDNet, but excluding any dividend payable in
shares of ZDNet stock, we will credit to ZD, and charge against ZDNet, a
corresponding amount in respect of ZD's retained interest in ZDNet.
Specifically, the corresponding amount will equal (1) the aggregate amount of
such dividend times (2) a fraction, the numerator of which is the number of
shares issuable with respect to ZD's retained interest in ZDNet and the
denominator of which is the number of shares of ZDNet stock then outstanding.

  This amount can also be expressed as follows:

Mandatory Dividend, Redemption or Exchange on Disposition of All or
Substantially All of the Assets of a Group

  If we dispose of all or substantially all of the assets of a group to one or
more persons or entities, in one transaction or a series of related
transactions, collectively, a "disposition", and the disposition is not an
exempt disposition as defined below, we would be required, by the 85th trading
day after the consummation of such disposition, to choose one of the following
three alternatives:

  . declare and pay a dividend to holders of the series of common stock that
    relates to that group in cash, securities (other than common stock of
    Ziff-Davis Inc.) or other property, or a combination thereof, in an
    amount having a fair value equal to their proportionate interest in the
    net proceeds of such disposition,

  . redeem from holders of the series of common stock that relates to that
    group, for cash, securities, other than common stock of Ziff-Davis Inc.,
    or other property, or a combination thereof, in an amount having a fair
    value equal to their proportionate interest in the net proceeds of such
    disposition, all of the outstanding shares of the relevant series of
    common stock (or, if such group continues after such disposition to own
    any material assets other than the proceeds of such disposition, a number
    of shares of such series of common stock having an aggregate average
    market value, during the 20 consecutive trading day period beginning on
    the 16th trading day immediately following the date on which the
    disposition is consummated, equal to such fair value) or

  . issue shares of the series of common stock that does not relate to that
    group in exchange for all of the outstanding shares of the series of
    common stock that relates to that group at a 10% premium, based on the
    average market value of the relevant series of common stock as compared
    to the average market value of the other series of common stock during
    the 20 consecutive trading day period beginning on the 16th trading day
    immediately following the date on which the disposition is consummated.

  In connection with any special dividend on, or redemption of, ZDNet stock as
described above, we will credit to ZD, and charge against ZDNet, a
corresponding amount in respect of ZD's retained interest in ZDNet.
Specifically, the corresponding amount will equal

 . the aggregate fair value of such dividend or redemption times

 . a fraction, the numerator of which is the number of shares issuable with
   respect to ZD's retained interest in ZDNet and the denominator of which is
   the number of shares of ZDNet stock then outstanding.

  This amount can also be represented by the following:

<TABLE>
<S>                          <C>

  (Aggregate Fair Value)  X  (Number of Shares Issuable with Respect to ZD's Retained Interest)
  ---------------------------------------------------------------------------------------------
                        (Number of Shares of ZDNet stock Outstanding)
</TABLE>

  In addition, in connection with any redemption of ZDNet stock as described
above, we will decrease the number of shares issuable with respect to ZD's
retained interest in ZDNet by the same proportion as the proportionate
decrease in outstanding shares of ZDNet caused by such redemption.

                                      161
<PAGE>

  At any time within one year after completing any dividend or partial
redemption of the sort referred to above, we will have the right to issue
shares of the series of common stock that does not relate to the group in
question in exchange for outstanding shares of the series of common stock that
relates to that group at a 10% premium. The exchange ratio that will result in
a 10% premium will be calculated based on the average market value of the
relevant series of common stock as compared to the average market value of the
other series of common stock during the 20 consecutive trading day period
ending on the 5th trading day immediately preceding the date on which Ziff-
Davis Inc. mails the notice of exchange to holders of the relevant series. In
determining whether to effect any such exchange following such a dividend or
partial redemption, we would, in addition to other matters, consider:

  . whether the remaining assets of such group continue to constitute a
    viable business,

  . the number of shares of such common stock remaining issued and
    outstanding,

  . the per share market price of such common stock and

  . the ongoing cost of continuing to have a separate series of such common
    stock outstanding.

  The following terms used in this prospectus have the meanings specified in
our restated charter and are set forth below:

  All or substantially all of the assets of either group means a portion of
such assets that represents at least 80% of the then-current fair value of the
assets of such group.

  Exempt disposition means any of the following:

  . a disposition in connection with the liquidation, dissolution or winding-
    up of Ziff-Davis Inc. and the distribution of assets to stockholders,

    determined by the board of directors in its sole discretion,

  . a disposition by either group for which Ziff-Davis Inc. receives
    consideration primarily consisting of equity securities, including,
    without limitation:

    . capital stock of any kind,

    . interests in a general or limited partnership,

    . interests in a limited liability company or

    . debt securities convertible into or exchangeable for any of the
      above, or options or warrants to acquire any of the above,

   in each case without regard to the voting power or other management or
   governance rights associated therewith, of:

    . an entity which is primarily engaged or proposes to engage primarily
      in one or more businesses similar or complementary to businesses
      conducted by such group prior to the disposition, as determined by
      the board of directors in its sole discretion,

    . a dividend, out of ZDNet's assets, to holders of ZDNet stock, and a
      transfer of a corresponding amount to ZD in respect of its retained
      interest in ZDNet,

                                      162

  . any other disposition, if

    . at the time of the disposition there are no shares of ZD stock
      outstanding,

    . at the time of the disposition there are no shares of ZDNet stock
      outstanding or

    . before the 30th trading day following the disposition we have mailed
      a notice stating that we are exercising our right to exchange all of
      the outstanding shares of ZD stock or ZDNet stock for newly issued
      shares of the other series of common stock as contemplated under "--
      Optional Exchange of One Series of Common Stock for the Other Series"
      below.

    as the board of directors shall determine in good faith.

Any good faith board of directors' determination of fair value shall be
conclusive and binding on all stockholders.

  Market capitalization of either series of common stock on any date means the
market value of a share of such series on such date times the number of shares
of such series outstanding on such date. Shares issuable with respect to ZD's
retained interest in ZDNet are not considered to be outstanding unless and
until they are in fact issued to third parties.

  Market value of a share of any class or series of capital stock on any
trading day generally means the average of the high and low reported sale
prices of a share of such class or series on such trading day, subject to
certain exceptions described in our restated charter.

    investment banking and accounting fees and expenses and

  . any liabilities, contingent or otherwise, of, attributed to or related
    to, such group, including, without limitation, any liabilities for
    deferred taxes, any indemnity or guarantee obligations which are
    outstanding or incurred in connection with the disposition or otherwise,
    any liabilities for future purchase price adjustments and any

                                      163
<PAGE>

   obligations with respect to outstanding securities, other than common
   stock, attributed to such group, as determined in good faith by the board
   of directors.

  Proportionate interest of holders of ZDNet stock in the net proceeds of a
ZDNet disposition, or in the outstanding shares of common stock of any
subsidiaries holding ZDNet's assets and liabilities, means

  . the amount of such net proceeds, or the number of such shares, times

  . the number of shares of ZDNet stock outstanding divided by

  . the total number of notional ZDNet shares deemed outstanding.

This amount can also be expressed as follows:

                                       (Total Number of Notional ZDNet Shares
                                                 Deemed Outstanding)
(Net Proceeds or Number of Shares)  X  ----------------------------------------

shares of ZDNet stock outstanding plus the number of shares issuable with
respect to ZD's retained interest in ZDNet.

  Trading day means each weekday on which the relevant security or, if there
are two relevant securities, each relevant security, is traded on the principal
national securities exchange on which it is listed or admitted to trading or on

  . all of the businesses, assets and liabilities of Ziff-Davis Inc. and its
    subsidiaries, other than the businesses, assets and liabilities that are
    part of ZDNet,

  . the rights and obligations of ZD under any inter-group debt deemed to be
    owed to or by ZD, as such rights and obligations are defined in
    accordance with policies established from time to time by the board of
    directors, and

  . a proportionate interest in ZDNet, after giving effect to any options,
    preferred stock, other securities or debt issued or incurred by Ziff-

                                      164

      payable in shares of ZDNet stock, or as payment in a redemption of
      shares of ZDNet stock effected as a result of a ZDNet disposition,
      then the board of directors shall re-allocate from ZDNet to ZD cash
      or other assets having a fair value equal to the aggregate fair value
      of the cash, other assets or securities so transferred times a
      fraction, the numerator of which shall equal the number of shares
      Issuable with respect to ZD's retained interest in ZDNet on the
      record date for such dividend or distribution, or on the date of such

</TABLE>

  ZDNet means:

  . the online business division of Ziff-Davis Inc., including all of the
    businesses, assets and liabilities of Ziff-Davis Inc. and its
    subsidiaries that the board of directors has allocated to ZDNet but
    excluding any ownership interest in Ziff-Davis Inc.'s ZDU and ZDTV
    businesses, as of the date on which our restated charter becomes
    effective under Delaware law. We call the date our restated charter
    becomes effective, the "effective date".

  . any assets or liabilities acquired or incurred by Ziff-Davis Inc. or any
    of its subsidiaries after the effective date in the ordinary course of
    business and attributable to ZDNet,

  . any businesses, assets or liabilities acquired or incurred by Ziff-Davis

      payable in shares of ZDNet stock, or as payment in a redemption of
      shares of ZDNet stock effected as a result of a ZDNet disposition,

      of the cash, other assets or securities so transferred times a
      fraction, the numerator of which shall equal the number of shares
      Issuable with respect to ZD's retained interest in ZDNet on the

Optional Exchange of One Series of Common Stock for the Other Series

  We will have the right, at any time before ZDNet stock exceeds the 65% of
total market capitalization trigger, to issue shares of ZD stock in exchange
for outstanding shares of ZDNet stock at a premium. The premium will initially
be 25%, for exchanges occurring in the first quarter after issuance, and will
decline each quarter over a period of 3 years to 15%.

  We will have the right, at any time after ZDNet stock exceeds the 65% of
total market capitalization trigger but before ZDNet stock falls below the 50%
of total market capitalization threshold, to issue shares of ZDNet stock in
exchange for outstanding shares of ZD stock at a 15% premium.

  The exchange ratio that will result in the specified premium will be
calculated based on the average market value of ZD stock as compared to the
average market value of ZDNet stock during the 20 consecutive trading day
period ending on, and including, the 5th trading day immediately preceding the
date on which we mail the notice of exchange to holders of the outstanding
shares being exchanged.

  In addition, we will have the right, if ZDNet stock exceeds the 65% of total
market capitalization trigger and thereafter falls below the 50% of total
market capitalization threshold, and regardless of whether ZDNet stock
thereafter remains below the 50% of total market capitalization threshold or
the 65% of total market capitalization trigger, to issue shares of either
series of common stock in exchange for outstanding shares of the other series
of common stock on a value for value basis.

  The exchange ratio that will result in a value for value exchange will be
based on the average market value of the series of the common stock being
exchanged as compared to the average market value of the other series of common
stock during the 20 consecutive

                                      166
<PAGE>

trading day period ending on, and including, the 5th trading day immediately
preceding the date on which we mail the notice of exchange to holders of the
outstanding shares being exchanged.

  ZDNet stock will exceed the 65% of total market capitalization trigger if the
market capitalization of the outstanding ZDNet stock exceeds 65% of the total
market capitalization of both series of common stock for 30 trading days during
any 60 consecutive trading day period. Thereafter, ZDNet stock will fall below
the 50% of total market capitalization threshold if, after exceeding the 65% of
total market capitalization trigger, the market capitalization of the
outstanding ZDNet stock falls below 50% of the total market capitalization of
both series of common stock for 30 trading days during any 60 consecutive
trading day period.

  If we have the right, on the date on which we mail a notice of exchange as
contemplated above, to issue shares of ZD stock or ZDNet stock in exchange for
outstanding shares of the other series of common stock as described above, we
will not lose that right even if ZDNet stock subsequently exceeds the 65% of
total market capitalization trigger or falls below the 50% of total market
capitalization threshold.

Optional Exchange for Stock of a Subsidiary

  At any time at which all of the assets and liabilities of a group, and no
other assets or liabilities of Ziff-Davis Inc. or any subsidiary thereof, are
held directly or indirectly by one or more wholly owned subsidiaries of Ziff-
Davis Inc., the "group subsidiaries", we will have the right to deliver to
holders of the relevant series of common stock their proportionate Interest in
all of the outstanding shares of the common stock of the group subsidiaries in
exchange for all of the outstanding shares of such series of common stock.

  . If the series of common stock being exchanged is ZD stock and the number
    of shares issuable with respect to ZD's retained interest in ZDNet is
    greater than zero, we will also issue a number of shares of ZDNet stock
    equal to the then current number of shares issuable with respect to ZD's
    retained interest in ZDNet and deliver those shares to the holders of ZD
    stock or to one of the group subsidiaries, at our option.

  . If the series of common stock being exchanged is ZDNet stock and the
    number of shares issuable with respect to ZD's retained interest in ZDNet
    is greater than zero, so that less than all of the shares of common stock
    of the group subsidiaries are being delivered to the holders of ZDNet
    stock, we may retain the remaining shares of common stock of the group
    subsidiaries or distribute those shares as a dividend on ZD stock.

General Dividend, Exchange and Redemption Provisions

  If we complete a disposition of all or substantially all of the assets of a
group, other than an exempt disposition, we would be required, not more than
the 10 Trading Days after the consummation of such disposition, to issue a
press release specifying:

  . the net proceeds of such disposition,

                                      167
<PAGE>

  . the number of shares of the series of common stock related to such group
    then outstanding,

  . the number of shares of such series of common stock issuable upon
    conversion, exchange or exercise of any convertible or exchangeable
    securities, options or warrants and the conversion, exchange or exercise
    prices thereof and

  . if the group is ZDNet, the number of shares issuable with respect to ZD's
    retained interest in ZDNet.

Not more than 30 trading days after such consummation, we would be required to
announce by press release which of the actions specified in the first paragraph
under "--Mandatory Dividend, Redemption or Exchange on Disposition of All or
Substantially All of the Assets of a Group" we have determined to take, and
upon making that announcement, that determination would become irrevocable. In
addition, we would be required, not more than 30 trading days after such
consummation and not less than 10 trading days before the applicable payment
date, redemption date or exchange date, to send a notice by first-class mail,
postage prepaid, to holders of the relevant series of common stock at their
addresses as they appear on our transfer books.

  . If we determine to pay a special dividend, we would be required to
    specify in the notice (1) the record date for such dividend, (2) the
    payment date of such dividend, which cannot be more than 85 trading days
    after such consummation, and (3) the aggregate amount and type of
    property to be paid in such dividend and the approximate per share amount
    thereof.

  . If we determine to undertake a redemption, we would be required to
    specify in the notice (1) the date of redemption, which cannot be more
    than 85 trading days after such consummation, (2) the aggregate amount
    and type of property to be paid as a redemption price and the approximate
    per share amount thereof, (3) if less than all shares of the relevant
    series of common stock are to be redeemed, the number of shares to be
    redeemed and (4) the place or places where certificates for shares of
    such series of common stock, properly endorsed or assigned for transfer,
    unless we waive such requirement, should be surrendered in return for
    delivery of the cash, securities or other property to be paid by Ziff-
    Davis Inc. in such redemption.

  . If we determine to undertake an exchange, we would be required to specify
    in the notice (1) the date of exchange, which cannot be more than 85
    trading days after such consummation, (2) the number of shares of the
    other series of common stock to be issued in exchange for each
    outstanding share of such series of common stock and (3) the place or
    places where certificates for shares of such series of common stock,
    properly endorsed or assigned for transfer, unless we waive such
    requirement, should be surrendered in return for delivery of the other
    series of common stock to be issued by Ziff-Davis Inc. in such exchange.

  If we determine to complete any exchange described under "--Optional Exchange
of One Series of Common Stock for the Other Series" or "Optional Exchange for
Stock of a Subsidiary", we would be required, between 10 to 30 trading days
before the exchange date, to send a notice by first-class mail, postage
prepaid, to holders of the relevant series of common stock at their addresses
as they appear on our transfer books, specifying (1) the

                                      168
<PAGE>

exchange date and the other terms of the exchange and (2) the place or places
where certificates for shares of such series of common stock, properly endorsed
or assigned for transfer, unless we waive such requirement, should be
surrendered for delivery of the stock to be issued or delivered by Ziff-Davis
Inc. in such exchange.

  Neither the failure to mail any required notice to any particular holder nor
any defect therein would affect the sufficiency thereof with respect to any
other holder or the validity of any dividend, redemption or exchange.

  If we are redeeming less than all of the outstanding shares of a series of
common stock as described above, we would redeem such shares pro rata or by lot
or by such other method as the board of directors determines to be equitable.

  No holder of shares of a series of common stock being exchanged or redeemed
will be entitled to receive any cash, securities or other property to be
distributed in such exchange or redemption until such holder surrenders
certificates for such shares, properly endorsed or assigned for transfer, at
such place as we specify, unless we waive such requirement. As soon as
practicable after our receipt of certificates for such shares, we would deliver
to the person for whose account such shares were so surrendered, or to the
nominee or nominees of such person, the cash, securities or other property to
which such person is entitled, together with any fractional payment referred to
below, in each case without interest. If less than all of the shares of common
stock represented by any one certificate were to be exchanged or redeemed, we
would also issue and deliver a new certificate for the shares of such common
stock not exchanged or redeemed.

  We would not be required to issue or deliver fractional shares of any capital
stock or any other fractional securities to any holder of common stock upon any
exchange, redemption, dividend or other distribution described above. If more
than one share of common stock were held at the same time by the same holder,
we may aggregate the number of shares of any capital stock that would be
issuable or any other securities that would be distributable to such holder
upon any such exchange, redemption, dividend or other distribution. If there
are fractional shares of any capital stock or any other fractional securities
remaining to be issued or distributed to any holder, we would, if such
fractional shares or securities were not issued or distributed to such holder,
pay cash in respect of such fractional shares or securities in an amount equal
to the fair value thereof, without interest.

  From and after the date set for any exchange or redemption, all rights of a
holder of shares of common stock that were exchanged or redeemed would cease
except for the right, upon surrender of the certificates representing such
shares, to receive the cash, securities or other property for which such shares
were exchanged or redeemed, together with any fractional payment as provided
above, in each case without interest and, if such holder was a holder of record
as of the close of business on the record date for a dividend not yet paid, the
right to receive such dividend. A holder of shares of common stock being
exchanged would not be entitled to receive any dividend or other distribution
with respect to shares of the other series of common stock until after the
shares being exchanged are surrendered as contemplated above. Upon such
surrender, we would pay to the holder the

                                      169
<PAGE>

amount of any dividends or other distributions, without interest, which
theretofore became payable with respect to a record date occurring after the
exchange, but which were not paid by reason of the foregoing, with respect to
the number of whole shares of the other series of common stock represented by
the certificate or certificates issued upon such surrender. From and after the
date set for any exchange, we would, however, be entitled to treat the
certificates for shares of common stock being exchanged that were not yet
surrendered for exchange as evidencing the ownership of the number of whole
shares of the other series of common stock for which the shares of such common
stock should have been exchanged, notwithstanding the failure to surrender such
certificates.

  We would pay any and all documentary, stamp or similar issue or transfer
taxes that might be payable in respect of the issue or delivery of any shares
of capital stock and/or other securities on any exchange or redemption
described herein. We would not, however, be required to pay any tax that might
be payable in respect of any transfer involved in the issue or delivery of any
shares of capital stock and/or other securities in a name other than that in
which the shares so exchanged or redeemed were registered, and no such issue or
delivery will be made unless and until the person requesting such issue pays to
Ziff-Davis Inc. the amount of any such tax or establishes to our satisfaction
that such tax has been paid.

  We may, subject to applicable law, establish such other rules, requirements
and procedures to facilitate any dividend, redemption or exchange contemplated
as described above as the board of directors may determine to be appropriate
under the circumstances.

Voting Rights

  Holders of ZD stock and ZDNet stock will vote together as one class on all
matters as to which common stockholders generally are entitled to vote, unless
a separate class vote is required by applicable law. On all such matters for
which no separate vote is required,

  . each outstanding share of ZD stock entitles the holder to one vote and

  . each outstanding share of ZDNet stock entitles the holder to a number of
    votes, calculated to the nearest five decimal places, equal to the
    average market value of a share of ZDNet stock divided by the average
    market value of a share of ZD stock during the 20 consecutive trading day
    period ending on, and including, the 5th trading day before the
    applicable record date.

  The voting formula is intended to equate the proportionate voting rights of
each series of common stock to its respective market values at the time of any
vote. On matters where holders of either series of common stock are entitled to
vote as a separate class, each share of that series would be entitled to one
vote in the separate vote on such matter.

  The relative voting rights of ZD stock and ZDNet stock will fluctuate from
time to time based on the respective market values of the two series of common
stock. Fluctuations in the relative voting rights of ZD stock and ZDNet stock
could influence an investor interested in acquiring and maintaining a fixed
percentage of the voting power in Ziff-Davis Inc. to acquire such percentage of
all series of common stock, and would limit the ability of

                                      170
<PAGE>

investors in one series to acquire for the same consideration relatively more
or less votes per share than investors in the other series.

  When holders of ZD stock and ZDNet stock vote together as a single class, the
holders of the series of common stock having a majority of the votes will be in
a position to control the outcome of the vote even if the matter involves a
conflict of interest between the holders of ZD stock and holders of ZDNet
stock.

  The Delaware general corporation law requires a separate vote of holders of
shares of common stock of any series on any amendment if the amendment would
increase or decrease the par value of the shares of such series or alter or
change the powers, preferences or special rights of the shares of such series
so as to affect them adversely.

  After ZDNet stock is issued, we will set forth the number of outstanding
shares of ZD stock and ZDNet stock in our annual and quarterly reports filed
pursuant to the Exchange Act, and disclose in any proxy statement for a
stockholder meeting the number of outstanding shares and per share voting
rights of ZD stock and ZDNet stock.

Liquidation

  Upon voluntary or involuntary liquidation, dissolution or winding-up of Ziff-
Davis Inc., holders of ZD stock and ZDNet stock will be entitled to receive
their proportionate interest in the net assets of Ziff-Davis Inc., if any,
remaining for distribution to stockholders after (1) payment of or provision
for all liabilities, including contingent liabilities, of Ziff-Davis Inc. and
(2) payment of the liquidation preference payable to any holders of our
preferred stock.

  Such distributions will be made pro rata in accordance with the average
market value of a share of ZD stock divided by the average market value of a
share of ZDNet stock during the 20 consecutive trading day period ending on,
and including, the 5th trading day before the date of the first public
announcement of (1) a voluntary liquidation, dissolution or winding-up by Ziff-
Davis Inc. or (2) the institution of any proceeding for the involuntary
liquidation, dissolution or winding-up of Ziff-Davis Inc.

  The liquidation formula is intended to provide liquidation rights for each
series of common stock proportionate to the respective market values at the
time of any liquidation.

  Neither the merger nor consolidation of Ziff-Davis Inc. with any other
entity, nor a sale, transfer or lease of all or any part of the assets of Ziff-
Davis Inc., would alone be deemed a liquidation, dissolution or winding-up for
these purposes.

ZD's Retained Interest in ZDNet

  In this document, we call the percentage interest in ZDNet intended to be
represented at any time by the outstanding shares of ZDNet stock the
outstanding interest percentage, and we call the remaining percentage interest
in ZDNet intended to be represented at any time by ZD's retained interest in
ZDNet the retained interest percentage. At any time, the outstanding interest
percentage equals the number of shares of ZDNet stock outstanding

                                      171
<PAGE>

divided by the total number of notional ZDNet shares deemed outstanding,
expressed as a percentage. The outstanding interest percentage can also be
expressed as follows:

                  Number of Shares of ZDNet Stock Outstanding
           ---------------------------------------------------------
            Total Number of Notional ZDNet Shares Deemed Outstanding

  The retained interest percentage equals the number of shares issuable with
respect to ZD's retained interest in ZDNet divided by the total number of
notional ZDNet shares deemed outstanding, expressed as a percentage. The
retained interest can also be expressed as follows:

   Number of Shares Issuable with Respect to ZD's Retained Interest In ZDNet
   ----------------------------------------------------------------------
            Total Number of Notional ZDNet Shares Deemed Outstanding

  The sum of the outstanding interest percentage and the retained interest
percentage always equals 100%. Thus:

     Outstanding Interest Percentage + Retained Interest Percentage = 100%
   --------------------------------------------------------------------------

  At the time that we file the restated charter, the retained interest
percentage will be 100% and the outstanding interest percentage will be 0%.

 Number of Shares Issuable with Respect to ZD's Retained Interest in ZDNet

  The board of directors has determined that the initial number of shares
issuable with respect to ZD's retained interest in ZDNet will be 70,000,000. In
the offering, we will attribute the net proceeds of 1,500,000 shares to the
equity of ZDNet and will attribute the net proceeds of the remaining shares to
ZD in respect of its retained interest. The issuance of the 1,500,000 shares
will have no effect on the number of shares issuable with respect to ZD's
retained interest in ZDNet, but the issuance of the shares in respect of ZD's
retained interest will correspondingly reduce that number. Thus, after giving
effect to the offering,

  .  there will be 10,000,000 shares of ZDNet stock outstanding, or 11,500,000
     shares if the underwriters fully exercise their option to purchase
     additional shares,

  .  the number of shares issuable with respect to ZD's retained interest in
     ZDNet will decline to 61,500,000, or 60,000,000 if the underwriters fully
     exercise their option to purchase additional shares,

  .  the total number of notional ZDNet shares deemed outstanding will be
     71,500,000,

  .  the outstanding interest fraction will be approximately 14.0%, or
     approximately 16.1% if the underwriters fully exercise their option to
     purchase additional shares and

  .  the retained interest fraction will be approximately 86.0%, or
     approximately 83.9% if the underwriters fully exercise their option to
     purchase additional shares.

                                      172
<PAGE>

 Attribution of Issuances of ZDNet Stock

  After the offering, whenever we decide to issue shares of ZDNet stock, we
would determine, in our sole discretion, whether to attribute that issuance,
and the proceeds thereof:

  . to ZD in respect of its retained interest in ZDNet, in a manner analogous
    to a secondary offering of common stock of a subsidiary owned by a
    corporate parent, or

  . to ZDNet, in a manner analogous to a primary offering of common stock.

If we issue any shares of ZDNet stock and attribute that issuance, and the
proceeds thereof, to ZD in respect of its retained interest in ZDNet, the
number of shares issuable with respect to ZD's retained interest in ZDNet would
be reduced by the number of shares so issued, the number of outstanding shares
of ZDNet stock would be increased by the same amount, the total number of
notional ZDNet shares deemed outstanding would remain unchanged, the retained
interest percentage would be reduced and the outstanding interest percentage
would be correspondingly increased. If we instead attribute that issuance and
the proceeds thereof to ZDNet, the number of shares issuable with respect to
ZD's retained interest in ZDNet would remain unchanged, the number of
outstanding shares of ZDNet stock and the total number of notional ZDNet shares
deemed outstanding would be increased by the number of shares so issued, the
retained interest percentage would be reduced and the outstanding interest
percentage would be correspondingly increased.

 Issuances of ZDNet Stock as Distributions on ZD Stock

  We reserve the right to issue shares of ZDNet stock as a distribution on ZD
stock, although we do not currently intend to do so. If we did so, we would
attribute that distribution to ZD in respect of its retained interest in ZDNet.
As a result, the number of shares issuable with respect to ZD's retained
interest in ZDNet would be reduced by the number of shares so distributed, the
number of outstanding shares of ZDNet stock would be increased by the same
amount, the total number of notional ZDNet shares deemed outstanding would
remain unchanged, the retained interest percentage would be reduced and the
outstanding interest percentage would be correspondingly increased. If instead
we issued shares of ZDNet stock as a distribution on ZDNet stock, we would
attribute that distribution to ZDNet, in which case we would proportionately
increase the number of shares issuable with respect to ZD's retained interest
in ZDNet. As a result, the number of shares issuable with respect to ZD's
retained interest in ZDNet and the total number of notional ZDNet shares deemed
outstanding would each be increased by the same percentage as the number of
outstanding shares of ZDNet stock is increased and the retained interest
percentage and outstanding interest percentage would remain unchanged.

 Dividends on ZDNet Stock

  At the time of any dividend on the outstanding shares of ZDNet stock,
including any dividend required as a result of a disposition of all or
substantially all of the assets of

                                      173
<PAGE>

ZDNet, but excluding any dividend payable in ZDNet stock, we will credit to ZD,
and charge against ZDNet, a corresponding amount in respect of ZD's retained
interest in
ZDNet. Specifically, the corresponding amount will equal the aggregate amount
of such dividend times a fraction, the numerator of which is the number of
shares issuable with respect to ZD's retained interest in ZDNet and the
denominator of which is the number of shares of ZDNet stock then outstanding.

  This amount can also be expressed as follows:

<TABLE>
   <C>                                <S>   <C>
   (Aggregate Amount of Dividend on     X   (Number of Shares Issuable with Respect
   ZDNet Stock)                             to ZD's Retained Interest in ZDNet)
                                            ---------------------------------------
                                            (Number of Shares of ZDNet Stock
                                            Outstanding)
</TABLE>

 Repurchases of ZDNet Stock

  If we decide to repurchase shares of ZDNet stock, we would determine, in our
sole discretion, whether to attribute that repurchase and the cost thereof to
ZD, in a manner analogous to a purchase of common stock of a subsidiary by a
corporate parent, or to ZDNet, in a manner analogous to an issuer repurchase.
If we repurchase shares of ZDNet stock and attribute that repurchase and the
cost thereof to ZD, the number of shares issuable with respect to ZD's retained
interest in ZDNet would be increased by the number of shares so purchased, the
number of outstanding shares of ZDNet stock would be decreased by the same
amount, the total number of notional ZDNet shares deemed outstanding would
remain unchanged, the retained interest percentage would be increased and the
outstanding interest percentage would be correspondingly decreased. If we
instead attribute that repurchase and the cost thereof to ZDNet, the number of
shares issuable with respect to ZD's retained interest in ZDNet would remain
unchanged, the number of outstanding shares of ZDNet stock and the total number
of notional ZDNet shares deemed outstanding would be decreased by the number of
shares so repurchased, the retained interest percentage would be increased and
the outstanding interest percentage would be correspondingly reduced.

 Transfers of Cash or Other Property between ZD and ZDNet

  We may, in our sole discretion, determine to transfer cash or other property
of ZDNet to ZD in return for a decrease in ZD's retained interest in ZDNet, in
a manner analogous to a return of capital, or to transfer cash or other
property of ZD to ZDNet in return for an increase in ZD's retained interest in
ZDNet, in a manner analogous to a capital contribution. If we determine to
transfer cash or other property of ZDNet to ZD in return for a decrease in ZD's
retained interest in ZDNet, the number of shares issuable with respect to ZD's
retained interest in ZDNet and the total number of notional ZDNet shares deemed
outstanding would each be decreased by an amount equal to the fair value of
such cash or other property divided by the market value of a share of ZDNet
stock on the day of transfer, the number of outstanding shares of ZDNet stock
would remain unchanged, the retained interest percentage would be decreased and
the outstanding interest percentage would be correspondingly increased.

                                      174
<PAGE>

  If we instead determine to transfer cash or other property of ZD to ZDNet in
return for an increase in ZD's retained interest in ZDNet, the number of shares
issuable with respect to ZD's retained interest in ZDNet and the total number
of notional ZDNet shares deemed outstanding would each be increased by an
amount equal to the fair value of such cash or other property divided by the
market value of a share of ZDNet stock on the day of transfer, the number of
outstanding shares of ZDNet stock would remain unchanged, the retained interest
percentage would be increased and the outstanding interest percentage would be
correspondingly decreased.

  We may not attribute issuances of ZDNet stock to ZD, transfer cash or other
property of ZDNet to ZD in return for a decrease in its retained interest in
ZDNet or take any other
action to the extent that doing so would cause the number of shares issuable
with respect to ZD's retained interest in ZDNet to decrease below zero.

  For illustrations showing how to calculate the retained interest percentage,
the outstanding interest percentage, the number of shares issuable with respect
to ZD's retained interest in ZDNet and the total number of notional ZDNet
shares deemed outstanding after giving effect to certain hypothetical
dividends, issuances, repurchases and transfers, see "Illustration of Certain
Terms".

Effectiveness of Certain Terms

  The terms described under "-- Dividends", "--Mandatory Dividend, Redemption
or Exchange on Disposition of All or Substantially All of the Assets of a
Group", "--Optional Exchange of One Series of Common Stock for the Other
Series", "--Optional Exchange for Stock of a Subsidiary", "--Voting Rights" and
"--Liquidation" above apply only when there are shares of both series of common
stock outstanding.

Determinations by the Board

  The restated charter will provide that, subject to applicable law, any
determinations made by the board of directors in good faith under the charter
or in any certificate of designation filed pursuant thereto would be final and
binding on all stockholders of Ziff-Davis Inc.

Preemptive Rights

  Holders of ZD stock and ZDNet stock will not have any preemptive rights to
subscribe for any additional shares of capital stock or securities that we may
issue in the future.

Certain Other Provisions of the Amended Charter and By-laws

 Preferred Stock

  The restated charter, like our current charter, provides that the board of
directors may issue shares of preferred stock in one or more series from time
to time. The board of

                                      175
<PAGE>

directors has the authority to fix by resolution or resolutions the
designations and the powers, preferences and rights, and the qualifications,
limitations and restrictions thereof, of the shares of each series of preferred
stock, including without limitation, the following:

  . the distinctive serial designation of such series which shall distinguish
    it from other series,

  . the number of shares included in such series,

  . the dividend rate, or method of determining such rate, payable to holders
    of the shares of such series,

  . any condition upon which such dividends shall be paid and the date or
    dates upon which such dividends shall be payable,

  . whether dividends on the shares of such series shall be cumulative and,
    in the case of shares of any series having cumulative dividend rights,
    the date or dates or method of determining the date or dates from which
    dividends on the shares of such series shall be cumulative,

  . the amount or amounts which shall be payable out of the assets of Ziff-
    Davis Inc. to holders of the shares of such series upon voluntary or
    involuntary liquidation, dissolution or winding-up Ziff-Davis Inc. and
    the relative rights of priority, if any, of payment of the shares of such
    series,

  . the price or prices at which, the period or periods within which and the
    terms and conditions upon which the shares of such series may be
    redeemed, in whole or in part, at the option of Ziff-Davis Inc. or at the
    option of the holder or holders thereof or upon the happening of a
    specified event or events,

  . the obligation, if any, of Ziff-Davis Inc. to purchase or redeem shares
    of such series pursuant to a sinking fund or otherwise and the price or
    prices at which, the period or periods within which and the terms and
    conditions upon which the shares of such series shall be redeemed or
    purchased, in whole or in part, pursuant to such obligation,

  . whether or not the shares of such series shall be convertible or
    exchangeable, at any time or times at the option of the holder or holders
    thereof or at the option of Ziff-Davis Inc. or upon the happening of a
    specified event or events, into shares of any other class or classes or
    any other series of the same or any other class or classes of stock of
    Ziff-Davis Inc. and the price or prices or rate or rates of exchange or
    conversion and any adjustments applicable thereto and

  . whether or not holders of the shares of such series shall have voting
    rights, in addition to the voting rights provided by law, and if so the
    terms of such voting rights.

  Unless a corporation's certificate provides otherwise, Section 242(b)(2) of
the Delaware general corporation law automatically gives holders of the
outstanding shares of a class the option to vote as a class on amendments to
increase or decrease the number of authorized shares of such class. Our
restated charter provides, however, that, subject to the rights of holders of
any series of preferred stock, the number of authorized shares of any class or
series of preferred stock may be increased or decreased, but not below the
number of

                                      176
<PAGE>

shares thereof then outstanding, by the affirmative vote of holders of a
majority of the outstanding shares entitled to vote, irrespective of the
provisions of Section 242(b)(2) of the Delaware general corporation law or any
corresponding provision hereafter enacted.

 Staggered Board of Directors

  The board of directors is divided into three classes, each of whose members
serve for a staggered three-year term. Upon the expiration of the term of a
class of directors, directors in such class are elected for three-year terms at
the annual meeting of stockholders in the year in which such term expires. The
classification of the board of directors has the effect of making it more
difficult for stockholders to change the composition of the board of directors,
because only a minority of the directors are up for election at each annual
meeting, and the board of directors may not be replaced by vote of the
stockholders at any one time.

 Number of Directors; Removal; Filling Vacancies

  The number of members of the board of directors will be fixed from time to
time pursuant to our by-laws. Our by-laws provide that the board of directors
will consist of one or more members, the number of which is determined from
time to time by the board of directors. In the event of any increase or
decrease in the authorized number of directors:

  . a director shall nevertheless continue as a director of the class of
    which he is a member until the expiration of his current term, or his
    earlier death, retirement, resignation or removal and

  . newly created or eliminated directorships resulting from such increase or
    decrease shall be apportioned by the board of directors among the three
    classes of directors so as to maintain such classes as nearly equal in
    number as reasonably possible.

Directors may be removed only for cause. However, a director who is also an
officer may be removed upon ceasing to be an officer. Vacancies, whether
arising through death, retirement, resignation or removal of a director or
through an increase in the authorized number of directors of any class, may
only be filled by a majority vote of the remaining directors of the class in
which such vacancy occurs, the sole remaining director of that class if one
such director remains, the majority vote of the directors of the remaining
classes if no such director remains or stockholders at an annual meeting of
stockholders of Ziff-Davis Inc.

  A director elected to fill a vacancy shall serve for the remainder of his
term of office of the class to which he is elected. These provisions prevent
any stockholder from enlarging the board of directors and then filling the new
directorships with such stockholder's own nominees.

 No Stockholder Action by Written Consent; Special Meetings

  Any action required or permitted to be taken by the stockholders of Ziff-
Davis Inc. must be duly effected at a duly called annual or special meeting of
such holders and may not be taken by any consent in writing by such holders.
Special meetings of stockholders of

                                      177
<PAGE>

Ziff-Davis Inc. may be called only by the chairman of the board of directors or
the board of directors pursuant to a resolution stating the purpose or purposes
of the special meeting. Any power of stockholders to call a special meeting is
specifically denied. No business other than that stated in the notice shall be
transacted at any special meeting. These provisions have the effect of delaying
consideration of a stockholder proposal until the next annual meeting unless a
special meeting is called by the Chairman, Vice Chairman, President or the
board of directors for consideration of such proposal.

 Advance Notice for Stockholder Nominations and Proposals of New Business

  Our by-laws establish an advance notice procedure. This procedure requires
stockholders to deliver to Ziff-Davis Inc. notice of any proposal to be
presented or of a candidate to be nominated for election as a director of Ziff-
Davis Inc. not less than 60 nor more than 90 days prior to the date of the
meeting. However, if the date of the meeting is first publicly announced or
disclosed, in a public filing or otherwise, is less than 70 days prior to the
date of the meeting, such advance notice shall be given not more than 10 days
after such date is first so announced or disclosed. Accordingly, failure by a
stockholder to act in compliance with the notice provisions will mean that the
stockholder will not be able to nominate directors or propose new business.

 Amendments

  The affirmative vote of holders of at least 80% of the stock entitled to vote
generally in the election of directors, voting together as a single class, or a
majority of the board of directors, is required to amend provisions of our by-
laws relating to stockholder action without a meeting, the calling of special
meetings, the number, or manner of determining the number, of Ziff-Davis Inc.'s
directors, the election and term of Ziff-Davis Inc.'s directors, the filling of
vacancies and the removal of directors.

Certain Provisions of Delaware Law

  Ziff-Davis Inc. is subject to the business combination provisions of Section
203 of the Delaware general corporation law. In general, such provisions
prohibit a publicly-held Delaware corporation from engaging in various business
combination transactions with any interested stockholder for a period of three
years after the date of the transaction in which the person became an
interested stockholder unless:

  . the business combination transaction, or the transaction in which the
    interested stockholder became an interested stockholder, is approved by
    the board of directors prior to the date the interested stockholder
    obtained such status,

  . upon consummation of the transaction which resulted in the stockholder
    becoming an interested stockholder, the interested stockholder owned at
    least 85% of the voting stock of the corporation outstanding at the time
    the transaction commenced, excluding for purposes of determining the
    number of shares outstanding those shares owned by

    . persons who are directors and also officers and

                                      178
<PAGE>

    . employee stock plans in which employee participants do not have the
      right to determine confidentially whether shares held subject to the
      plan will be tendered in a tender or exchange offer or

  . on or subsequent to such date the business combination is approved by the
    board of directors and authorized at an annual or special meeting of
    stockholders by the affirmative vote of at least 66 2/3% of the
    outstanding voting stock which is not owned by the interested
    stockholder.

A business combination is defined to include mergers, asset sales and other
transactions resulting in financial benefit to a stockholder. In general, an
interested stockholder is a person who, together with affiliates and
associates, owns or, within three years, did own, 15% or more of a
corporation's voting stock. The statute could prohibit or delay mergers or
other takeover or change in control attempts with respect to Ziff-Davis Inc.
and, accordingly, may discourage attempts to acquire Ziff-Davis Inc. Since the
board of directors approved the acquisition of common stock by SOFTBANK
Holdings before SOFTBANK Holdings acquired such common stock, SOFTBANK Holdings
is not an interested stockholder for these purposes.

Limitations on Liability and Indemnification of Officers and Directors

  Section 102 of the Delaware general corporation law authorizes a Delaware
corporation to include a provision in its certificate of incorporation limiting
or eliminating the personal liability of its directors to the corporation or
its stockholders for monetary damages for breach of the directors' fiduciary
duty of care. The duty of care requires that, when acting on behalf of the
corporation, directors exercise an informed business judgment based on all
material information reasonably available to them. Absent the limitations
authorized by such provision, directors are accountable to corporations or
their stockholders for monetary damages for conduct constituting gross
negligence in the exercise of their duty of care. Although Section 102 of the
Delaware general corporation law does not change a director's duty of care, it
enables corporations to limit available relief to equitable remedies such as
injunction or rescission. Our restated charter and by-laws include provisions
which limit or eliminate the personal liability of Ziff-Davis Inc.'s directors
to the fullest extent permitted by Section 102 of the Delaware general
corporation law. Consequently, a director will not be personally liable to
Ziff-Davis Inc. or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for any breach of the directors' duty of
loyalty to Ziff-Davis Inc. or its stockholders, acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
unlawful payments of dividends or unlawful stock repurchases, redemptions or
other distributions and any transaction from which the director derived an
improper personal benefit.

  Our by-laws provide that the Ziff-Davis Inc. indemnify to the full extent
permitted by law any person made or threatened to be made a party to any
action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that such person or such person's testator
or intestate is or was a director, officer or employee of Ziff-Davis Inc. or
serves or served at the request of Ziff-Davis Inc. any other enterprise as a
director, officer or employee. Our by-laws provide that expenses, including
attorneys' fees,

                                      179
<PAGE>

incurred by any such person in defending any such action, suit or proceeding
will be paid or reimbursed by Ziff-Davis Inc. promptly upon receipt by it of an
undertaking of such person to repay such expenses if it shall ultimately be
determined that such person is not entitled to be indemnified by Ziff-Davis
Inc. The inclusion of these indemnification provisions in our by-laws is
intended to enable Ziff-Davis Inc. to attract qualified persons to serve as
directors and officers who might otherwise be reluctant to do so.

  The directors and officers of Ziff-Davis Inc. are insured under policies of
insurance maintained by Ziff-Davis Inc., subject to the limits of such
policies, against certain losses arising from any claim made against them by
reason of being or having been such officers or directors. In addition to the
protection available under our restated charter, by-laws and insurance
policies, we have entered into agreements with our outside directors to
indemnify them to the fullest extent permitted by law against losses arising
from any claim against them by reason of being or having been a director. In
addition, the limited liability provisions in our restated charter and the
indemnification provisions in our by-laws may discourage stockholders from
bringing a lawsuit against directors for breach of their fiduciary duty,
including breaches resulting from grossly negligent conduct, and may have the
effect of reducing the likelihood of derivative litigation against directors
and officers, even though such an action, if successful, might otherwise have
benefitted Ziff-Davis Inc. and our stockholders. Furthermore, a stockholder's
investment in Ziff-Davis Inc. may be adversely affected to the extent we pay
the costs of settlement and damage awards against directors and officers of
Ziff-Davis Inc. pursuant to the indemnification provisions in our by-laws. The
limited liability provisions in our restated charter will not limit the
liability of directors under federal securities laws.

  Section 203 of the Delaware general corporation law, and the provisions of
our restated charter and by-laws described above, may make it more difficult
for a third party to acquire or discourage bids for Ziff-Davis Inc. Section 203
and these provisions could have the effect of inhibiting attempts to change the
membership of the board of directors.

Stock Transfer Agent and Registrar

  The Bank of New York is the registrar and transfer agent for ZD stock and
ZDNet stock.

<PAGE>

                        SHARES ELIGIBLE FOR FUTURE SALE

  Prior to the offering, there has been no public market for ZDNet stock. We
cannot predict the effect, if any, that sales of shares or the availability of
shares for sale will have on the market price prevailing from time to time.
Future sales of substantial amounts of ZDNet stock in the public market, or the
perception that such sales may occur, could adversely affect the prevailing
market price of ZDNet stock. See "Risk Factors--Risk Factors Relating To ZDNet
Stock--The Market Price Of ZDNet Stock May Decline Due To Shares Of ZDNet Stock
Eligible For Future Sale".

  Upon completion of the offering, Ziff-Davis Inc. expects to have 10,000,000
shares of ZDNet stock outstanding or 11,500,000 shares if the underwriters
fully exercise their option to purchase additional shares. These shares will be
freely tradeable without restriction under the Securities Act, except for any
such shares which may be acquired by an affiliate of Ziff-Davis Inc. Rule 144
defines an affiliate of Ziff-Davis Inc. as a person that, directly or
indirectly, through one or more intermediaries, controls or is controlled by,
or is under common control with, Ziff-Davis Inc.

  Softbank has indicated it will not purchase any shares of ZDNet stock. Ziff-
Davis Inc. expects that certain directors and officers who may be considered to
be affiliates will acquire up to 100,000 shares of ZDNet stock in the offering.
These shares will be restricted securities (as that phrase is defined in Rule
144) and may not be resold without registration under the Securities Act unless
exempted from such registration, including among others, the exemption provided
by Rule 144 under the Securities Act. One year after the date of this
prospectus these shares of ZDNet stock will be eligible for sale in the public
market pursuant to Rule 144, subject to the volume limitations and other
restrictions described below.

  In general, under Rule 144 if a period of at least one year has elapsed since
the later of the date the restricted shares were acquired from Ziff-Davis Inc.
and the date they were acquired from an affiliate, then the holder of such
restricted shares, including an affiliate, is entitled to sell a number of
shares within any three-month period that:

  . does not exceed the greater of 1% of the then outstanding shares or

  . the average weekly reported volume of trading of such shares on the NYSE
    during the four calendar weeks preceding such sale.

  The holder may only sell such shares through unsolicited brokers'
transactions. Sales under Rule 144 are also subject to certain requirements
pertaining to:

  . the manner of such sales,

  . notices of such sales and

  . the availability of current public information concerning Ziff-Davis Inc.


                                      181
<PAGE>

  Under Rule 144 (k), a holder of restricted shares may sell shares immediately
without regard to the volume limitations and other restrictions described above
if:

  . a period of at least two years has passed between the later of (1) the
    date restricted securities were acquired from Ziff-Davis Inc. and (2) the
    date they were acquired from an affiliate, as applicable,

  . the holder is not an affiliate at the time of the sale and

  . has not been an affiliate for at least three months prior to the sale.

  After the offering is completed, certain employees of Ziff-Davis Inc. will
have the right to purchase approximately 10,026,000 additional shares of ZDNet
stock under employee stock options, subject to vesting periods. Also, assuming
the underwriters do not exercise their option to purchase additional shares,
after the offering is completed, Ziff-Davis Inc. will be entitled to issue up
to 70,000,000 shares of ZDNet stock. Of these shares, up to 61,500,000 shares
may be for the account of ZD in respect of its retained interest in ZDNet.

  Notwithstanding the information above, in connection with the offering, Ziff-
Davis Inc.
and the officers and directors referred to above have agreed that, during the
period ending 180 days after the date of the prospectus, they will not,
directly or indirectly:

  . offer,

  . pledge,

  . sell,

  . contract to sell,

  . sell any option or contract to purchase,

  . purchase any option or contract to sell,

  . grant any option, right or warrant to purchase,

  . lend or

  . otherwise transfer or dispose of,

any shares of ZDNet stock or any securities convertible into or exercisable or
exchangeable for ZDNet stock, unless they obtain the prior written consent of
the representatives of the underwriters on behalf of the underwriters. This
restriction applies whether such shares or any such securities are owned by
such person at the time or are thereafter acquired directly from Ziff-Davis
Inc.

  Ziff-Davis Inc. and the officers and directors referred to above have also
agreed that, during the period ending 180 days after the date of the
prospectus, they will not, directly or indirectly, enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of ZDNet stock.

  These restrictions apply whether any such transaction described above is to
be settled by delivery of ZDNet stock or such other securities, in cash or
otherwise.

                                      182
<PAGE>

  The restrictions described above do not apply to:

  . the sale to the underwriters of the shares of ZDNet stock under the
    underwriting agreement,

  . the issuance by Ziff-Davis Inc. of shares of ZDNet stock upon the
    exercise of an option or a warrant or the conversion of a security
    outstanding on the date of this prospectus of which the underwriters have
    been advised in writing,

  . the grant of options under existing employee benefit plans or

  . transactions by any person other than Ziff-Davis Inc. relating to shares
    of ZDNet stock or other securities acquired in open market transactions
    after the offering is completed.

                             ZIFF-DAVIS INC.'S DEBT

   The following summaries highlight key provisions of Ziff-Davis Inc.'s 8
 1/2% senior subordinated notes and credit facility. These summaries are not
 substitutes for the more detailed information contained in Ziff-Davis Inc.'s
 indenture and credit facility, copies of which have been filed as exhibits to
 this registration statement.


Notes

  General

  Concurrently with the initial public offering of our existing common stock on
April 28, 1998, Ziff-Davis Inc. sold $250 million in principal amount of 8 1/2%
senior subordinated notes due May 1, 2008. The notes are general unsecured
senior subordinated obligations of Ziff-Davis Inc. and rank on parity with all
other unsecured and subordinated indebtedness of Ziff-Davis Inc. The notes are
subordinated in right of payment to all senior indebtedness of Ziff-Davis Inc.,
as defined in the indenture for the notes.

  The notes are redeemable, at Ziff-Davis Inc.'s option, in whole or in part,
at any time after May 1, 2003, at redemption prices starting at 104.250% of
their principal amount and declining to 100% of their principal amount on or
after May 1, 2006, plus accrued and unpaid interest. In addition, upon a change
of control of Ziff-Davis Inc., as defined in the indenture for the notes, each
holder of notes will have the right to require Ziff-Davis Inc. to purchase such
holder's notes. Ziff-Davis Inc. will be permitted to redeem a portion of the
notes following one or more public equity offerings consummated prior to May 1,
2001.

  Covenants

  The indenture for the notes contains certain restrictive covenants, including
the following:

  . a limitation on the ability of Ziff-Davis Inc. and its restricted
    subsidiaries, as defined in the indenture, to incur any indebtedness
    other than permitted indebtedness, as defined in the indenture, or to
    incur senior subordinated indebtedness or certain indebtedness secured by
    liens,

  . a limitation on the ability of Ziff-Davis Inc. and its restricted
    subsidiaries to, directly or indirectly, make any restricted payment, as
    defined in the indenture, including payment of dividends, prepayment of
    subordinated indebtedness and the repurchase of capital stock,

  . a limitation on the ability of Ziff-Davis Inc. to suffer to exist certain
    dividend and other payment restrictions affecting its restricted
    subsidiaries,

  . a limitation on the ability of Ziff-Davis Inc. to sell or to permit any
    restricted subsidiary to issue or sell capital stock of a restricted
    subsidiary,


                                      184
<PAGE>

  . a limitation on the ability of Ziff-Davis Inc. and its restricted
    subsidiaries to consummate certain asset sales, as defined in the
    indenture, unless certain conditions are fulfilled and

  . limitations on any transaction with affiliates.

Certain of these covenants will terminate if and when the notes receive an
investment grade rating. In addition, the indenture limits the ability of Ziff-
Davis Inc. to merge with or to transfer all or substantially all of its assets
to another person. The notes provide for acceleration upon customary events of
default.

Credit Facility

  Ziff-Davis Inc. is party to a secured guaranteed credit agreement with The
Bank of New York, Morgan Stanley Senior Funding, DLJ Capital Funding and The
Chase Manhattan Bank to provide a $1.35 billion term credit facility. The
amount outstanding under this facility at December 31, 1998 was $1.220 billion.
The credit facility consists of:

  . a seven-year $400 million reducing revolving credit facility, with $270
    million drawn as of December 31, 1998,

  . a seven-year $450 million term loan and

  . an eight-year $500 million term loan.

There are various customary conditions to draw-downs under the revolving
commitments. The revolving credit commitments will be reduced and the $450
million term loan will be amortized, beginning in September 2000, by:

  . 10% in 2000, in two equal quarterly installments,

  . 20% in each of 2001, 2002, 2003 and 2004 in four equal quarterly
    installments and

  . 10% at final maturity in March 2005.

The $500 million term loan will be amortized, beginning in September 2000, by:

  . $2 million in 2000, in two equal quarterly installments,

  . $4 million in each of 2001, 2002, 2003, 2004 and 2005 in four equal
    quarterly installments and

  . $478 million at final maturity in March 2006.

  The credit facility is secured, in part, by a first priority security
interest in capital stock of certain subsidiaries of Ziff-Davis Inc. and is
guaranteed by certain wholly owned domestic subsidiaries of Ziff-Davis Inc., in
each case, including ZD Inc. and ZD Events.

  The credit facility contains certain customary affirmative and negative
covenants, including covenants with respect to:

  . the delivery of financial statements and other information,

  . limitations on dispositions of assets,

                                      185
<PAGE>

  . changes of business and ownership,

  .  mergers or acquisitions,

  .  restricted payments,

  .  indebtedness,

  .  loans and investments,

  .  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 also contains certain financial covenants.

  The failure to satisfy any of the covenants would constitute an event of
default under the credit facility. The credit facility also includes 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.

                     CERTAIN UNITED STATES TAX CONSEQUENCES

  The following discussion summarizes certain U.S. federal income tax
consequences of the ownership of ZDNet stock, including certain anticipated
U.S. income and estate tax consequences of the ownership and disposition of
ZDNet stock applicable to non-U.S. holders, as defined below, of such ZDNet
stock. This discussion does not consider the specific facts and circumstances
that may be relevant to particular holders and does not address the treatment
of holders of common stock under the laws of any state, local or foreign taxing
jurisdiction. This discussion is based on the tax laws of the U.S., including
the Internal Revenue Code, as amended to the date hereof, existing and proposed
regulations thereunder, and administrative and judicial interpretation thereof,
as currently in effect. These laws are subject to change, possibly on a
retroactive basis.


 You should consult your own tax advisors with regard to the application of
 the federal income tax laws to your particular situation, as well as to
 the applicability and effect of any state, local or foreign tax laws to
 which you may be subject.


General

  We believe that for federal income tax purposes ZDNet stock will be
considered common stock of Ziff-Davis Inc. Accordingly, we believe that for
federal income tax purposes neither we nor any U.S. holder will recognize any
income, gain or loss as a result of the issuance of ZDNet stock. You are a
"U.S. holder" for U.S. federal income tax purposes if you are a beneficial
owner of common stock and are:

  . a citizen or resident of the U.S.,

  . a corporation organized under the laws of the U.S. or any state,

  . an estate, the income of which is subject to U.S. federal income tax
   without regard to its source or

  . a trust, if a court within the U.S. is able to exercise primary
   supervision over the administration of the trust and one or more U.S.
   persons have the authority to control all substantial decisions of the
   trust.

  There are, however, no court decisions or other authorities bearing directly
on the classification of instruments with characteristics similar to those of
ZDNet stock. In addition, the IRS has announced that it will not issue advance
rulings on the classification of an instrument that has certain voting and
liquidation rights in an issuing corporation but whose dividend rights are
determined by reference to the earnings of a segregated portion of the issuing
corporation's assets, including assets held by a subsidiary.

  The current Presidential administration's budget proposals released on
February 1, 1999 would require the recognition of gain on the issuance of
certain tracking stock, such as ZDNet stock, and gives the Treasury Department
the authority to treat tracking stock as nonstock or as stock of another entity
as appropriate to prevent tax avoidance. The Treasury Department's explanation
expresses the view that the use of

                                      187
<PAGE>

tracking stock "is clearly outside the contemplation of" the Internal Revenue
Code and that "no inference regarding the tax treatment of [such stock] under
current law is intended by [the] proposal". Because the proposal would only be
effective for tracking stock issued on or after the date of enactment, the
proposal will likely not affect the re-classification of existing common stock
into ZD stock or the issuance of the ZDNet stock in the offering. If, however,
the proposals were to become law, it would affect future issuances of ZDNet
stock. Under such circumstances, Ziff-Davis Inc. might decide to exercise its
right to redeem all of the outstanding shares of ZDNet stock for ZD stock at a
premium, in order to eliminate any tracking stock from its capital structure.

Certain United States Tax Consequences to Non-U.S. Holders

  The following discussion summarizes certain U.S. federal income and estate
tax consequences of the ownership and disposition of common stock by "Non-U.S.
Holders". You are a "non-U.S. holder" for U.S. federal income tax purposes if
you are:

  . a non-resident alien individual,

  . a foreign corporation,

  . a foreign partnership or

  . an estate or trust that in either case is not subject to U.S. federal
   income tax on a net income basis on income or gain from common stock.

 Dividends

  If you are a non-U.S. holder of common stock, dividends paid to you are
subject to withholding of U.S. federal income tax at a 30% rate or at a lower
rate if so specified in an applicable income tax treaty. If, however, the
dividends are effectively connected with your conduct of a trade or business
within the U.S., and they are attributable to a permanent establishment that
you maintain in the U.S., if that is required by an applicable income tax
treaty as a condition for subjecting you to U.S. income tax on a net income
basis on such dividends, then such "effectively connected" dividends generally
are not subject to withholding tax. Instead, such effectively connected
dividends are taxed at rates applicable to U.S. citizens, resident aliens and
domestic U.S. corporations.

  Effectively connected dividends received by a non-U.S. corporation may, under
certain circumstances, be subject to an additional "branch profits tax" at a
30% rate or at a lower rate if so specified in an applicable income tax treaty.

  Under currently effective U.S. Treasury regulations, dividends paid to an
address in a foreign country are presumed to be paid to a resident of that
country, unless the payor has knowledge to the contrary, for purposes of the
30% withholding tax discussed above. Under current interpretations of U.S.
Treasury regulations, this presumption that dividends paid to an address in a
foreign country are paid to a resident of that country, unless the payor has
knowledge to the contrary, also applies for the purposes of determining whether
a lower tax treaty rate applies.

                                      188
<PAGE>

  Under U.S. Treasury regulations, which will generally apply to dividends paid
after December 31, 1999 (the "final withholding regulations"), if you claim the
benefit of a lower treaty rate, you must satisfy certain certification
requirements. In addition, in the case of common stock held by a foreign
partnership, the certification requirements generally will apply to the
partners of the partnership and the partnership must provide certain
information, including a U.S. taxpayer identification number. The final
withholding regulations also provide look-through rules for tiered
partnerships.

  If you are eligible for a reduced rate of U.S. withholding tax under a tax
treaty, you may obtain a refund of any excess amounts withheld by filing a
refund claim with the IRS.

 Gain On Disposition Of Common Stock

  If you are a non-U.S. holder you generally will not be subject to U.S.
federal income tax on gain recognized on a disposition of common stock unless:

  . the gain is effectively connected to your conduct of a trade or business
   in the U.S. (and the gain is attributable to a permanent establishment
   that you maintain in the U.S., if that is required by an applicable income
   tax treaty as a condition for subjecting you to U.S. taxation on a net
   income basis on gain from the sale or other disposition of the common
   stock),

  . you are an individual, you hold the common stock as a capital asset and
   you are present in the U.S. for 183 or more days in the taxable year of
   the sale and certain other conditions exist or

  . Ziff-Davis Inc. is or has been a "United States real property holding
   corporation" for federal income tax purposes and you held, directly or
   indirectly, at any time during the five-year period ending on the date of
   disposition, more than 5% of the common stock of Ziff-Davis Inc. (and you
   are not eligible for any treaty exemption).

  Effectively connected gains recognized by a corporate non-U.S. holder may
also, under certain circumstances, be subject to an additional "branch profits
tax" at a 30% rate or at a lower rate if so specified in an applicable income
tax treaty.

  Ziff-Davis Inc. has not been, is not, and does not anticipate becoming a
"United States real property holding corporation" for federal income tax
purposes.

 Federal Estate Taxes

  Common stock held by a non-U.S. holder at the time of death will be included
in the holder's gross estate for U.S. federal estate tax purposes, unless an
applicable estate tax treaty provides otherwise.

Information Reporting And Backup Withholding

  In general, U.S. information reporting requirements and backup withholding
tax will not apply to dividends paid to you if you are either:

  . subject to the 30% withholding tax discussed above or

                                      189
<PAGE>

  . not subject to the 30% withholding tax because an applicable tax treaty
   reduces or eliminates such withholding tax,

although dividend payments to you will be reported for purposes of the
withholding tax (see "--Dividends" above). If you do not meet either of these
requirements for exemption and you fail to provide certain information
(including your U.S. taxpayer identification number) or otherwise establish
your status as an "exempt recipient", you may be subject to backup withholding
of U.S. federal income tax at a rate of 31% on dividends paid with respect to
common stock.

  Under current law, the payor may generally treat dividends paid to a payee
with a foreign address as exempt from backup withholding and information
reporting unless the payor has definite knowledge that the payee is a U.S.
person. However, under the final withholding regulations, dividend payments
generally will be subject to information reporting and backup withholding
unless certain certification requirements are met. (See the discussion under
"--Dividends" for the rules applicable to foreign partnerships under the final
withholding regulations.)

  U.S. information reporting and backup withholding requirements generally will
not apply to a payment of the proceeds of a sale of common stock made outside
the U.S. through an office outside the U.S. of a non-U.S. broker. However, U.S.
information reporting, but not backup withholding, will apply to a payment made
outside the U.S. of the proceeds of a sale of common stock through an office
outside the U.S. of a broker that:

  . is a U.S. person,

  . derives 50% or more of its gross income for certain periods from the
   conduct of a trade or business in the U.S.,

  . is a "controlled foreign corporation" as to the U.S. or

  . with respect to payments made after December 31, 1999, is a foreign
   partnership, if at any time during its tax year:

    . one or more of its partners are U.S. persons, as defined in U.S.
     Treasury regulations, who in the aggregate hold more than 50% of the
     income or capital interest in the partnership or

    . such foreign partnership is engaged in a U.S. trade or business,
     unless the broker has documentary evidence in its records that the
     holder or beneficial owner is a non-U.S. person or otherwise
     establishes an exemption.

  Payment of the proceeds of a sale of common stock to or through a U.S. office
of a broker is subject to both U.S. backup withholding and information
reporting unless the holder certifies its non-U.S. status under penalty of
perjury or otherwise establishes an exemption.

  A non-U.S. holder generally may obtain a refund of any excess amounts
withheld under the backup withholding rules by filing a refund claim with the
IRS.

                         ILLUSTRATION OF CERTAIN TERMS

  The following illustrations show how to calculate the Retained Interest
Percentage, the Outstanding Interest Percentage, the Number of Shares Issuable
with Respect to ZD's Retained Interest in ZDNet and the Total Number of
Notional ZDNet Shares Deemed Outstanding after giving effect to certain
hypothetical dividends, issuances, repurchases and transfers, in each case
based on the assumptions set forth herein. In these illustrations, the Number
of Shares Issuable with Respect to ZD's Retained Interest in ZDNet is initially
assumed to be 100. Unless otherwise specified, each illustration below should
be read independently as if none of the other transactions referred to below
had occurred. Actual calculations may be slightly different due to rounding.

  "Total Number of Notional ZDNet Shares Deemed Outstanding" means the number
of shares of ZDNet Stock outstanding plus the Number of Shares Issuable with
Respect to ZD's Retained Interest in ZDNet.

  At any given time, the percentage interest in ZDNet intended to be
represented by the outstanding shares of ZDNet Stock (i.e., the Outstanding
Interest Percentage) is equal to:

                       Outstanding Shares of ZDNet Stock
      ----------------------------------------------------------
            Total Number of Notional ZDNet Shares Deemed Outstanding

and the remaining percentage interest in ZDNet intended to be represented by
ZD's Retained Interest in ZDNet (i.e., the Retained Interest Percentage) is
equal to:

            Number of Shares Issuable with Respect to ZD's Retained
                               Interest in ZDNet
      ----------------------------------------------------------
            Total Number of Notional ZDNet Shares Deemed Outstanding

  The sum of the Outstanding Interest Percentage and the Retained Interest
Percentage would always equal 100%. In our example, before the first issuance
the Number of Shares Issuable with Respect to ZD's Retained Interest in ZDNet
and the Total Number of Notional ZDNet Shares Deemed Outstanding are each equal
to 100, the Retained Interest Percentage is 100% and the Outstanding Interest
Percentage is 0%.

The Offering

  The following illustrations reflect an assumed issuance by Ziff-Davis Inc. of
15 shares of ZDNet Stock in the offering.

 Offering For Account Of ZD

  Assume the issuance is attributed to ZD in respect of its Retained Interest
(as currently planned), with the net proceeds credited solely to ZD.

  . The Number of Shares Issuable with Respect to ZD's Retained Interest in
    ZDNet would decrease by the number of shares of ZDNet Stock sold for the
    account of ZD.

      Number of Shares Issuable with Respect to ZD's Retained Interest in
       ZDNet prior to the offering......................................... 100
      Shares issued in the offering........................................  15
                                                                            ---
          Number of Shares Issuable with Respect to ZD's Retained Interest
           in ZDNet after the offering.....................................  85
                                                                            ===
</TABLE>
  . As a result, the issued and outstanding shares (15) would represent an
    Outstanding Interest Percentage of 15%, calculated as follows:

                                       15
                                   --------
                                    15 + 85

   The Retained Interest Percentage would accordingly be 85%.

  . In this case, in the event of any dividend or other distribution paid on
    the outstanding shares of ZDNet Stock (other than a dividend or other
    distribution payable in shares of ZDNet Stock), ZD would be credited, and
    ZDNet would be charged, with an amount equal to 567% (representing the
    ratio of the Number of Shares Issuable with Respect to ZD's Retained
    Interest in ZDNet (85) to the total number of shares of ZDNet Stock
    issued and outstanding following the offering (15)) of the aggregate
    amount of such dividend or distribution. If, for example, a dividend of
    $1.00 per share were declared and paid on the 15 shares of ZDNet Stock
    outstanding (an aggregate of $15), ZD would be credited with $85, and
    ZDNet would be charged with that amount in addition to the $15 dividend
    paid to the holders of ZDNet Stock (a total of $100).

 Offering For Account Of ZDNet

  Assume the issuance is attributed to ZDNet as an increase in its equity, with
the net proceeds credited solely to ZDNet.

<TABLE>
      <S>                                                                     <C>

</TABLE>

  . The Number of Shares Issuable with Respect to ZD's Retained Interest in
    ZDNet (100) would remain unchanged.

                                      I-2
<PAGE>

  . As a result, the issued and outstanding shares (15) would represent an
    Outstanding Interest Percentage of about 13%, calculated as follows:

                                       15
                                    --------
                                    15 + 100

The Retained Interest Percentage would accordingly be about 87%.

  . In this case, in the event of any dividend or other distribution paid on
    the outstanding shares of ZDNet Stock (other than a dividend or other
    distribution payable in shares of ZDNet Stock), ZD would be credited, and
    ZDNet would be charged, with an amount equal to 667% (representing the
    ratio of the Number of Shares Issuable with Respect to ZD's Retained
    Interest in ZDNet (100) to the total number of shares of ZDNet Stock
    issued and outstanding following the offering (15)) of the aggregate
    amount of such dividend or distribution.

Additional Offerings of ZDNet Stock

  The following illustrations reflect an assumed issuance of an additional 15
shares of ZDNet Stock after the assumed initial issuance of 15 shares for the
account of ZD.

                                    30 + 70

   The Retained Interest Percentage would accordingly be reduced to 70%.

  . In this case, in the event of any dividend or other distribution paid on
    ZDNet Stock (other than a dividend or other distribution payable in
    shares of ZDNet Stock), ZD

                                      I-3

   would be credited, and ZDNet would be charged, with an amount equal to
   233% (representing the ratio of the Number of Shares Issuable with Respect
   to ZD's Retained Interest in ZDNet (70) to the total number of shares of
   ZDNet Stock issued and outstanding following the additional offering (30))
   of the aggregate amount of such dividend or distribution.

</TABLE>

  . The Number of Shares Issuable with Respect to ZD's Retained Interest in
    ZDNet (85) would remain unchanged.

  . As a result, the total issued and outstanding shares (30) would in the
    aggregate represent an Outstanding Interest Percentage of about 26%,
    calculated as follows:

                                       30
                                   --------
                                    30 + 85

   The Retained Interest Percentage would accordingly be reduced to about 74%.

  . In this case, in the event of any dividend or other distribution paid on
    ZDNet Stock (other than a dividend or other distribution payable in
    shares of ZDNet Stock), ZD would be credited, and ZDNet would be charged,
    with an amount equal to 283% (representing the ratio of the Number of
    Shares Issuable with Respect to ZD's Retained Interest in ZDNet (85) to
    the total number of shares of ZDNet Stock issued and outstanding
    following the additional offering (30)) of the aggregate amount of such
    dividend or distribution.

 Offerings Of Convertible Securities

  If we were to issue any securities convertible into or exercisable for shares
of ZDNet Stock, the Outstanding Interest Percentage and the Retained Interest
Percentage would be unchanged at the time of such issuance. If any shares of
ZDNet Stock were issued upon conversion or exercise of such securities,
however, then the Outstanding Interest Percentage and the Retained Interest
Percentage would be affected as shown above under "Additional Offering for
Account of ZD", if such securities were attributed to ZD, or under "Additional
Offering for Account of ZDNet", if such securities were attributed to ZDNet.

Repurchases of ZDNet Stock

 Repurchase For Account Of ZDNet With Participation By ZD

  Assume the repurchase is attributed to ZDNet, with the cost being charged
solely against ZDNet. Further assume that the repurchase is made in connection
with a tender offer for 5, or 33%, of the then outstanding shares at a price of
$20 per share, and that the board of directors determines to transfer cash or
other assets from ZDNet to ZD to hold constant the Outstanding Interest
Percentage and Retained Interest Percentage.

</TABLE>

  . In order to hold constant the Outstanding Interest Percentage and
    Retained Interest Percentage, the board of directors determines that the
    Market Value of a share of ZDNet Stock in this context is $20 and
    transfer from ZDNet to ZD an amount of cash or other assets equal to 567%
    (representing the ratio of the Number of Shares Issuable with Respect to
    ZD's Retained Interest in ZDNet (85) to the total number of shares of
    ZDNet Stock issued and outstanding (15), in each case immediately prior
    to the repurchase) of the aggregate amount of the cash paid in the tender
    offer to holders of outstanding shares of ZDNet Stock ($100), or a total
    of $567.

  . In that case, the Number of Shares Issuable with Respect to ZD's Retained
    Interest in ZDNet (85) would decrease by the amount of cash so
    transferred ($567) divided by the Market Value per share of ZDNet Stock
    ($20).

   The Retained Interest Percentage would accordingly continue to be 85%.

  . Assuming that the board of directors transferred only half of the $567
    amount, or $283.50, from ZDNet to ZD, the Number of Shares Issuable with
    Respect to ZD's Retained Interest in ZDNet (85) would decrease by the

 ZDNet Stock Dividend On ZD Stock

  Assume 1,000 shares of ZD Stock are outstanding and Ziff-Davis Inc. declares
a dividend of 1/20 of a share of ZDNet Stock on each outstanding share of ZD
Stock.

   hold 50 shares of ZDNet Stock, which would be intended to represent a 50%
   interest in the value attributable to ZDNet.

  Ziff-Davis Inc. is offering shares of ZDNet stock by this prospectus. In
order to prepare separate financial statements for ZD and ZDNet, we have
separated ZDNet, our online business division, from ZD, which includes the rest
of our businesses and a retained interest in ZDNet, and we have allocated all
of our consolidated assets, liabilities, revenue, expenses and cash flow
between ZD and ZDNet. Thus, the financial statements of ZD and ZDNet, taken
together, comprise all of the accounts included in the corresponding
consolidated financial statements of Ziff-Davis Inc. Because ZD currently has a
100% Retained Interest in ZDNet, the financials of ZD reflect a 100% equity
interest in ZDNet in a manner similar to the equity method of accounting
provided by APB No. 18, The Equity Method of Accounting for Investments in
Common Stock.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Ziff-Davis Inc.

In our opinion, the accompanying combined balance sheets and the related
combined statements of operations, cash flows and changes in division equity,
present fairly, in all material respects, the financial position of ZDNet (a
division of Ziff-Davis Inc., the "Company") at December 31, 1997 and 1998, and
the results of its operations and its cash flows for the period from February
29, 1996 to December 31, 1996 and for the years ended December 31, 1997 and
1998, 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 described in Note 1 to the financial statements, ZDNet is a division of
Ziff-Davis Inc.; accordingly, the financial statements of ZDNet should be read
in conjunction with the audited financial statements of Ziff-Davis Inc.

1. Organization and Basis of Presentation

 Formation of Ziff-Davis Inc.

  Ziff-Davis Inc. was formed through an initial public offering and
reorganization that were completed on May 4, 1998 (described below). Prior to
that date, the predecessors of Ziff-Davis Inc. (currently named ZD Inc. and ZD
Events Inc.) were wholly owned indirect subsidiaries of SOFTBANK Corp.
(together with its non-Ziff-Davis Inc. affiliates, "Softbank").

  ZDNet is the online business division of Ziff-Davis Inc. ZD is the division
of Ziff-Davis Inc. (formerly ZD Inc.) focused on the business of print
publishing, trade shows and conferences, market research and education. Each of
ZD and ZDNet is sometimes referred to herein as a "Group".

  In order to prepare separate financial statements for ZD and ZDNet, Ziff-
Davis Inc. has allocated all of its consolidated assets, liabilities, revenue,
expenses and cash flow between ZD and ZDNet. Thus, the financial statements of
ZD and ZDNet, taken together, comprise all of the accounts included in the
corresponding consolidated financial statements of Ziff-Davis Inc.

  ZDNet's financial statements reflect the application of certain cash
management and allocation policies adopted by the Board of Directors of Ziff-
Davis Inc. (the "Board"). These policies are summarized in Note 4 under
"Certain Cash Management and Allocation Policies".

  Even though Ziff-Davis Inc. has allocated all of its consolidated assets,
liabilities, revenue, expenses and cash flow between ZD and ZDNet, that
allocation and the division of Ziff-Davis Inc.'s common stock will not change
the legal title to any assets or responsibility for any liabilities and will
not affect the rights of any creditors. Holders of ZDNet Stock (as described
below) will continue to be common stockholders of Ziff-Davis Inc. and, as such,
will be subject to all risks associated with an investment in Ziff-Davis Inc.
and all of its businesses, assets and liabilities.

  Financial impacts that occur at ZD that affect Ziff-Davis Inc.'s consolidated
results of operations or financial position could affect the results of
operations or financial condition of ZDNet or the market price of ZDNet Stock.
In addition, net losses of ZD, and any dividends or distributions on or
repurchases of ZD Stock, will reduce the assets of Ziff-Davis Inc. legally
available for dividends on ZDNet Stock. Accordingly, financial information for
ZDNet should be read in conjunction with financial information for ZD and
financial information for Ziff-Davis Inc.

 Relationship with Softbank and MAC

  SOFTBANK Corp. is the indirect majority stockholder of Ziff-Davis Inc.
SOFTBANK Corp. is a Japanese corporation which at the time of the acquisition
of the MAC Assets was majority owned directly and indirectly by its president,
Mr. Son. As of December 31, 1998 Mr. Son owned approximately 45% of SOFTBANK
Corp. (50.2% as of December 31, 1997). MAC, also a Japanese corporation, was
wholly owned by Mr. Son.

 Acquisition of ZDNet

  In February 1996, SOFTBANK Corp. acquired the stock of Ziff-Davis Holdings
Corp. ("Holdings") for an aggregate purchase price of approximately
$1,800,000,000 plus transaction costs. Softbank is 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 wholly owned holding company, MAC Inc. (MAC Inc.
and affiliates hereinafter referred to as "MAC"). Concurrent with the
acquisition, in a separate agreement, MAC, directly or through wholly owned
affiliates, acquired certain assets and assumed certain liabilities of ZD Inc.
(the "MAC Assets"), a wholly owned subsidiary of Holdings (formerly Ziff-Davis
Inc.), for an aggregate purchase price of approximately $302,000,000. ZDNet
comprised a portion of the MAC Assets.

  These acquisitions 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 relating to ZDNet was
$72,692,000.

 Acquisition of GameSpot, Inc.

  In January 1997, SOFTBANK Holdings Inc., an affiliate of Ziff-Davis Inc.
("SBH"), acquired 70% of GameSpot, Inc. ("GameSpot", formerly SpotMedia
Communications, Inc.) for approximately $3,000,000. Funds for this acquisition
were provided by Ziff-Davis Inc. to SBH. As part of the initial public offering
and reorganization that was completed on May 4, 1998 (described below),
GameSpot was contributed to ZDNet. Because GameSpot and Ziff-Davis Inc. were
under common control at the time of the transaction, the GameSpot acquisition
has been accounted for in a manner similar to a pooling of interests and
GameSpot's results have been included in ZDNet's results since the time of
common ownership (January 1997). The "pooling" of GameSpot results in a non-
cash capital contribution of $5,167,000 for the year ended December 31, 1997.

 Reorganization and initial public offering

  On February 4, 1998, a nonstock corporation, ZD Inc., was formed in
contemplation of a reorganization and initial public offering of Ziff-Davis
Inc. Upon completion of the initial

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

public offering (described below), Ziff-Davis Inc. was renamed ZD Inc., ZDCF
was renamed ZD Events Inc. and ZD Inc. was renamed Ziff-Davis Inc.

  On May 4, 1998, SOFTBANK Corp., through its wholly owned subsidiary, SBH
completed a reorganization whereby the common stock of ZD Inc. and ZD Events
Inc. were contributed to Ziff-Davis Inc. in exchange for 73,619,355 shares of
Ziff-Davis Inc.'s common stock. Concurrent with the reorganization, Ziff-Davis
Inc. (1) completed an initial public offering of 25,800,000 common shares at an
initial public offering purchase price of $15.50 per share, (2) issued
$250,000,000 of 8 1/2% subordinated notes due 2008, (3) entered into a
$1,350,000,000 credit facility with a group of banks under which $1,250,000,000
was borrowed and (4) converted $908,673,000 of intercompany indebtedness to
equity. In addition, Ziff-Davis Inc. received approximately $9,107,000 of fixed
assets from Kingston Technology Company ("Kingston"), a related party, in
exchange for 580,645 shares of Ziff-Davis Inc.'s common stock and $107,000 in
cash. These assets have been subsequently leased back to Kingston. Total shares
of common stock issued to Softbank were 74,200,000. The transactions described
above are herein referred to as the "Reorganization".

  Proceeds, net of transaction costs, from the initial public offering and
funding transactions in the Reorganization of $1,863,260,000 were used to
complete the purchase of certain assets from MAC for $370,000,000, and repay
intercompany indebtedness. The ZDNet business was a portion of the MAC Assets
acquired at that time.

  On May 28, 1998, Ziff-Davis Inc.'s U.S. underwriters exercised their option
to purchase 2.0 million additional shares of common stock to cover over-
allotments. Ziff-Davis Inc. purchased the additional shares from SBH resulting
in no change to the total number of shares outstanding. On December 31, 1998
SBH contributed 71,619,355 shares of Ziff-Davis Inc.'s common stock to SOFTBANK
America, Inc., an affiliate of SOFTBANK Corp.

 Investment in Deja News Inc.

  On July 22, 1998, ZDNet purchased $5,000,000 in Series C, convertible, non-
voting preferred shares of Deja News Inc., an Internet discussion network. This
investment is being accounted for at cost.

2. ZDNet Stock Proposal (unaudited)

  The stockholders of Ziff-Davis Inc. are scheduled to vote on a proposal (the
"Tracking Stock Proposal") to authorize the issuance of a new series of common
stock, to be designated as Ziff-Davis Inc. --ZDNet Common Stock ("ZDNet
Stock"), intended to reflect the performance of Ziff-Davis Inc.'s online
business division ("ZDNet"). The majority owner of the common stock of Ziff-
Davis Inc. has committed to vote for the Tracking Stock

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

Proposal. Before the ZDNet Stock is first issued, Ziff-Davis Inc.'s existing
common stock will be re-classified as Ziff-Davis Inc.--ZD Common Stock ("ZD
Stock") and that stock will be intended to reflect the performance of Ziff-
Davis Inc.'s other businesses and a "Retained Interest" in ZDNet (i.e., Ziff-
Davis Inc.'s retained interest in ZDNet excluding the interest intended to be
represented by outstanding shares of ZDNet Stock)(collectively, "ZD").

  ZD currently has a 100% Retained Interest in ZDNet. Following approval of the
Tracking Stock Proposal, Ziff-Davis Inc. currently plans to offer to the
public, for cash, 10,000,000 shares of ZDNet Stock intended to represent
approximately 14% of the equity value attributed to ZDNet. Ziff-Davis Inc.
expects to offer ZDNet Stock to the public sometime in the first or second
quarter of 1999. However, Ziff-Davis Inc. could choose to conduct the offering
at a later time, or not to make the offering at all, depending on the
circumstances at the time. In addition to or instead of the offering, Ziff-
Davis Inc. reserves the right to distribute ZDNet Stock to stockholders of
Ziff-Davis Inc.

  Currently, Ziff-Davis Inc. provides all funding for ZD and ZDNet as described
in Note 4 under "Certain Cash Management and Allocation Policies". Ziff-Davis
Inc. intends to continue these practices until ZDNet Stock is first issued.
Accordingly, no interest expense or income to or from ZD has been reflected in
the financial statements of ZDNet for any period prior to the date on which
ZDNet Stock is first issued.

  After the date on which ZDNet Stock is first issued, for financial statement
purposes, the following policies will apply except to the extent the Board
rescinds, modifies or adds to them:

    (a) Ziff-Davis Inc. will attribute each future incurrence or issuance of
  external debt or preferred stock (and the proceeds thereof) to ZD, except
  in cases where the Board determines otherwise. The Board may determine from
  time to time to attribute an incurrence or issuance of debt or preferred
  stock (and the proceeds thereof) to ZDNet to the extent that Ziff-Davis
  Inc. incurs or issues the debt or preferred stock for the benefit of ZDNet,
  but the Board will not be required to do so.

    (b) Ziff-Davis Inc. will attribute each future issuance of ZD Stock (and
  the proceeds thereof) to ZD. Ziff-Davis Inc. may attribute any future
  issuance of ZDNet Stock (and the proceeds thereof) to ZD in respect of its
  Retained Interest in ZDNet (in a manner analogous to a secondary offering
  of common stock of a subsidiary owned by a corporate parent) or to ZDNet
  (in a manner analogous to a primary offering of common stock). Dividends on
  and repurchases of ZD Stock will be charged against ZD, and dividends on
  and repurchases of ZDNet Stock will be charged against ZDNet. In addition,
  at the time of any dividend on ZDNet Stock, Ziff-Davis Inc. will credit to
  ZD,

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

  and charge against ZDNet, a corresponding amount in respect of ZD's
  Retained Interest in ZDNet.

    (c) Whenever ZDNet holds cash (other than cash of ZDNet's foreign
  operations or cash of ZDNet's operations that are not wholly owned), ZDNet
  will normally transfer that cash to ZD. Conversely, whenever ZDNet has a
  cash need (other than cash needs of ZDNet's foreign operations or cash
  needs of ZDNet's operations that are not wholly owned), ZD will normally
  fund that cash need. However, the Board will determine, in its sole
  discretion, whether to provide any particular funds to either Group. The
  Board is not obligated to cause either Group to provide funds to the other
  Group if the Board determines it is not in the best interest of Ziff-Davis
  Inc. to do so.

    (d) Ziff-Davis Inc. will account for all cash transfers from one Group to
  or for the account of the other Group (other than transfers in return for
  assets or services rendered or transfers in respect of ZD's Retained
  Interest that correspond to dividends paid on ZDNet Stock) as inter-Group
  revolving credit advances unless (1) the Board determines that a given
  transfer (or type of transfer) should be accounted for as a long-term loan,
  (2) the Board determines that a given transfer (or type of transfer) should
  be accounted for as a capital contribution increasing ZD's Retained
  Interest in ZDNet or (3) the Board determines that a given transfer (or
  type of transfer) should be accounted for as a return of capital reducing
  ZD's Retained Interest in ZDNet. There are no specific criteria to
  determine when Ziff-Davis Inc. will account for a cash transfer as a long-
  term loan, a capital contribution or a return of capital rather than an
  inter-Group revolving credit advance. The Board would make such a
  determination in the exercise of its business judgment at the time of such
  transfer (or the first of such type of transfer) based upon all relevant
  circumstances. Factors the Board would consider include (1) the current and
  projected capital structure of each Group, (2) the relative levels of
  internally generated funds of each Group, (3) the financing needs and
  objectives of the recipient Group, (4) the investment objectives of the
  transferring Group, (5) the availability, cost and time associated with
  alternative financing sources and (6) prevailing interest rates and general
  economic conditions.

    (e) Any cash transfer accounted for as an inter-Group revolving credit
  advance will bear interest at the rate at which Ziff-Davis Inc. could
  borrow such funds on a revolving credit basis (as the Board determines in
  its sole discretion). Any cash transfer accounted for as a long-term loan
  will have interest rate, amortization, maturity, redemption and other terms
  that generally reflect the then prevailing terms on which Ziff-Davis Inc.
  could borrow such funds (as the Board determines in its sole discretion).

    (f) Any cash transfer from ZD to ZDNet (or for its account) accounted for
  as a capital contribution will correspondingly increase ZDNet's division
  equity and ZD's

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

  Retained Interest in ZDNet. As a result, the number of shares of ZDNet
  Stock that could be issued by Ziff-Davis Inc. for the account of ZD in
  respect of its Retained Interest in ZDNet (the "Number of Shares Issuable
  with Respect to ZD's Retained Interest in ZDNet") will increase by (1) the
  amount of such capital contribution divided by (2) the Market Value of
  ZDNet Stock on the date of transfer.

    (g) Any cash transfer from ZDNet to ZD (or for its account) accounted for
  as a return of capital will correspondingly reduce ZDNet's division equity
  and ZD's Retained Interest in ZDNet. As a result, the Number of Shares
  Issuable with Respect to ZD's Retained Interest in ZDNet will decrease by
  (1) the amount of such return of capital divided by (2) the Market Value of
  ZDNet Stock on the date of transfer.

3. Summary of Significant Accounting Policies

 Principles of combination

  The combined financial statements include the accounts of ZDNet. All
significant transactions within the ZDNet division have been eliminated on
combination.

 Cash and cash equivalents

  ZDNet considers all highly liquid investments with an original maturity of 3
months or less to be cash equivalents.

 Concentration of credit risk

  ZDNet places its temporary cash investments with high credit quality
financial institutions. At times, such investments may be in excess of
federally insured limits. ZDNet has not experienced losses in such accounts.

  ZDNet's customers represent a variety of technology companies in the U.S. and
other countries. ZDNet 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 cost or estimated fair value at
the date of acquisition. Depreciation is computed using the straight-line
method half-year convention over the estimated useful lives of the assets which
range from 3 to 8 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.

                                     ZDNET
                        (a division of Ziff-Davis Inc.)

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
                   (numbers rounded to the nearest thousand)


 Intangible assets

  Intangible assets consist principally of advertising lists, subscriber lists
and goodwill. Amortization of these assets is computed on a straight-line basis
over estimated useful lives. Identifiable intangible assets are amortized over
a period of 2 to 9 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 10 to 20 years. (See Note 6.) ZDNet assesses the
recoverability of 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 value of assets, an impairment loss is recognized to reduce the
carrying value of the intangibles estimated recoverable value. ZDNet has not
experienced any impairment of its intangible assets.

 Revenue recognition

  ZDNet's revenue is derived principally from the sale of advertisements on
short-term contracts. Advertising revenue is recognized ratably in the period
in which the advertisement is displayed, provided that no significant
obligations remain and collection of the resulting receivable is probable.
ZDNet's obligations typically include guarantees of a minimum number of
"impressions", or times that an advertisement appears in pages viewed by users
of ZDNet's online properties. To the extent minimum guaranteed impressions are
not met, ZDNet defers recognition of the corresponding revenue until the
remaining guaranteed impression levels are achieved.

  Revenue from subscription based fees and services is recognized evenly over
the term of the contract.

  Revenue from barter transactions is recognized during the period in which the
advertisements are displayed. Barter transactions are recorded at the lower of
estimated fair value of the goods or services received or the estimated fair
value of the advertisements given. To date, barter transactions have been
insignificant.

 Foreign currency

  The effect of translating foreign currency financial statements into U.S.
dollars is included in the cumulative translation adjustment account in
division equity. Gains and losses on foreign currency transactions, which are
not significant to operations, have been included in selling, general and
administrative expenses. ZDNet has not historically entered into forward
currency contracts.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

 Income taxes

  ZDNet 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.

 Stock-based compensation

  ZDNet has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees ("APB 25"), to account for stock
options. Effective January 1, 1996, ZDNet adopted the disclosure only
provisions of Statement of Financial Accounting Standards ("SFAS") No. 123,
Accounting for Stock-Based Compensation.

 Comprehensive income

  ZDNet implemented SFAS No. 130 Reporting Comprehensive Income, effective
January 1, 1998. This standard requires ZDNet to report the total changes in
division equity that do not result directly from transactions with
stockholders, including those which do not affect retained earnings. These
changes are not material to ZDNet's combined financial statements.

 New accounting pronouncement

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133
Accounting for Derivative Instruments and Hedging Activities, SFAS No. 133
establishes accounting and reporting standards for derivative instruments and
for hedging activities and is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. ZDNet does not expect that the adoption of SFAS
No. 133 will have a material impact on ZDNet's results of operations. ZDNet
will adopt SFAS No. 133 beginning with its 2000 financial statements.

4. Certain Cash Management and Allocation Policies

  ZDNet's financial statements reflect the application of certain cash
management and allocation policies summarized below. The Board may rescind,
modify or add to any of these policies.

 Treasury activities

  Ziff-Davis Inc. manages most treasury activities on a centralized,
consolidated basis. These activities include the investment of surplus cash,
the issuance, repayment and repurchase of short-term and long-term debt, and
the issuance and repurchase of common stock and preferred stock. Each of ZDNet
and ZD generally remits its cash receipts (other than receipts of foreign
operations or operations that are not wholly owned) to Ziff-Davis Inc., and
Ziff-Davis Inc. generally funds ZDNet's cash disbursements (other than
disbursements of foreign operations or operations that are not wholly owned),
on a daily basis.

  In the financial statements of ZD and ZDNet, (1) all external debt and equity
transactions (and the proceeds thereof) were attributed to ZD, (2) whenever
ZDNet held cash (other than cash of ZDNet's foreign operations or cash of
ZDNet's operations that are not wholly owned), that cash was transferred to ZD
and accounted for as a return of capital (i.e., as a reduction in ZDNet's
division equity and ZD's Retained Interest in ZDNet) and (3) whenever ZDNet had
a cash need (other than cash needs of ZDNet's foreign operations or cash needs
of ZDNet's operations that are not wholly owned), that cash need was funded by
ZD and accounted for as a capital contribution (i.e., as an increase in ZDNet's
division equity and ZD's Retained Interest in ZDNet). Accordingly, no interest
expense or income to or from ZD has been reflected in the financial statements
of ZDNet.

 Corporate general and administrative expenses

  Ziff-Davis Inc. allocates the cost of certain corporate general and
administrative services and shared services (including certain legal,
accounting (tax and financial), information systems, telecommunications,
purchasing, marketing, intellectual property, public relations, corporate
office and travel expenses) (collectively, "Central Services") to ZDNet based
on utilization. Where determinations based on utilization alone are
impracticable, Ziff-Davis Inc. uses other methods and criteria that management
believes to be equitable and to provide a reasonable estimate of the cost
attributable to ZDNet.

 Taxes

  Federal income taxes, which are determined on a consolidated basis, except
for GameSpot, are allocated to ZDNet (and reflected in its financial
statements) in accordance

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

with Ziff-Davis Inc.'s tax allocation policy. In general, this policy provides
that the consolidated tax provision (and related tax payments or refunds) are
allocated between the Groups based principally upon the financial income,
taxable income, credits and other amounts directly related to the respective
Groups. Tax benefits that cannot be used by the Group generating such
attributes, but can be utilized on a consolidated basis, are allocated to the
Group that generated such benefits. As a result, the allocated Group amounts of
taxes payable or refundable are not necessarily comparable to those that would
have resulted if the Groups had filed separate tax returns.

 Royalty charges

  ZD charges ZDNet an annual fee for the use of various brands and editorial
content. The current annual fee, which is reflected in ZDNet's financial
statements as part of its production and content costs, is equal to 5% of the
first $100,000,000 of ZDNet's revenue for the year, 4% of the next $50,000,000
of ZDNet's revenue for that year and 3% of any incremental revenue over
$150,000,000 for that year. The Board may at some point in the future change
this fee as it, in its sole discretion, deems appropriate in light of the
circumstances from time to time.

  Intangible assets primarily relate to the acquisition of the MAC Assets. As
discussed in Note 1, the acquisition was accounted for under the purchase
method of accounting. As such, the purchase price of this acquisition was
allocated to tangible and identifiable intangible assets with the remaining
amount being allocated to goodwill.

  Advertising lists and subscriber lists were recorded at estimated fair value
as determined by an income approach.

  All intangible assets are being amortized using the straight-line method over
estimated useful lives, up to 20 years. In determining the estimated useful
lives, ZDNet considered its competitive position in the markets in which it
operates, the historical attrition rates of advertisers, subscribes 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

  Provision (benefit) for income taxes and related assets and liabilities
attributed to ZDNet are determined in accordance with Ziff-Davis Inc.'s tax
allocation policy. (See Note 4.)

  ZDNet (excluding GameSpot) has been included in a consolidated federal income
tax return, except for the periods in which it was owned by MAC Inc. (described
in Note 1). GameSpot is a 70% owned subsidiary and files separate federal and
state income tax returns on a stand-alone basis.

  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 ZDNet's inability to deduct losses incurred by ZDNet while owned
by MAC. In addition, tax benefits attributable to losses in foreign
jurisdictions and certain U.S. losses are subject to the establishment of a
valuation allowance inasmuch as such loss carryforwards are not expected to be
utilized in the future.

  Following is a summary of the components of the deferred tax accounts at
December 31, 1997 and 1998:

  The valuation allowance primarily relates to tax benefits of foreign net
operating loss carryforwards acquired in the MAC Asset purchase which are not
expected to be realized. No deferred tax asset has been established for the
U.S. losses generated by ZDNet while owned by MAC since these losses will not
be available for use by Ziff-Davis Inc.

  ZDNet has U.S. and foreign net operating loss carryforwards at December 31,
1998 of approximately $23,000,000, which will begin to expire in 2000. The
utilization of certain net operating loss carryforwards of approximately
$10,000,000 is subject to limitations primarily due to the change of ownership
resulting from Softbank's acquisition of Holding's stock. Management believes
that such limitations will not significantly affect Ziff-Davis Inc.'s ability
to recognize the deferred tax asset relating to the carryforwards. Accordingly,
no valuation allowance to reduce the deferred tax asset relating to the
carryforwards has been established.

  ZDNet transacts business with a group of companies affiliated through common
ownership with Softbank and has various transactions and relationships with

the group. Due to 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.

  ZD provides all necessary funding for the operations and investments of
ZDNet; this funding is accounted for as capital contributions. (See Notes 2 and
4.) For the period from February 29, 1996 to December 31, 1996 and the years
ended December 31, 1997 and 1998, such capital contributions were $13,630,000,
$25,831,000 and $14,269,000, respectively.

  The amounts receivable or payable to affiliated companies are included in
accounts receivable, net or accounts payable in the accompanying balance

contributions may be made by Ziff-Davis Inc. 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 ZDNet up to certain specified percentages. Employees are generally
eligible to participate in a plan upon joining Ziff-Davis Inc. and receive
matching contributions after one year of employment. ZDNet made contributions
to the plan totaling $447,000, $751,000 and $1,111,000 for the period from
February 29, 1996 to December 31, 1996 and the years ended December 31, 1997
and 1998, respectively.

11. Stock Compensation Plans

 SOFTBANK Executive Stock Option Plans

  The Softbank Executive Stock Option Plans provide for the granting of
nonqualified stock options (the "Softbank Options") to purchase the common
stock of SOFTBANK Corp. to officers, directors and key employees of Ziff-Davis
Inc. SOFTBANK Corp. is a publicly traded company in Japan. 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, 1998, 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. On January 19,
1998, the exercise price of all of the shares outstanding under option
agreements were reset to (Yen)4,000, the closing market price on Japan's Tokyo
Stock Exchange First Section at that date. In conjunction with the repricing,
those options previously exercisable at December 31, 1997 could only be
exercised after July 19, 1998. The repricing of the stock options did not
result in compensation expense to ZDNet.

 1998 Incentive Compensation Plan and the 1998 Non-Employee Directors' Stock
Option Plan

  In 1998, Ziff-Davis Inc. adopted the 1998 Incentive Compensation Plan (the
"Incentive Plan") and the 1998 Non-Employee Directors' Stock Option Plan (the
"Non-Employee Directors' Plan"). The Incentive Plan provides for the grant of
options, stock appreciation rights, stock awards and other interests in Ziff-
Davis Inc.'s common stock to key employees of Ziff-Davis Inc. and its
affiliates and consultants. The Non-Employee Directors' Plan provides for the
grant of stock options to non-employee directors. Ziff-Davis Inc. has reserved
8,500,000 shares of common stock for issuance under the Incentive Plan and
200,000 shares of common stock for issuance under the Non-Employee Directors'
Plan. During 1998, Ziff-Davis Inc. granted options to purchase 339,000 shares
to ZDNet employees 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.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


  On September 23, 1998, the Board approved the reduction of the exercise price
of all options outstanding under the Incentive Plan from $16.00 to $6.00, the
closing market price of Ziff-Davis Inc.'s common stock on that date. In
addition, the vesting period of the options was extended by three months. The
repricing did not result in compensation expense to ZDNet.

  On December 21, 1998 the Board approved an amendment to the Incentive Plan to
permit grants of options and other stock-based awards with respect to any
series of common stock of Ziff-Davis Inc. and to increase the number of shares
available for issuance from 8,500,000 shares to 17,827,500 shares.

  In addition, on December 21, 1998, the Board approved the grant of options to
acquire an aggregate of approximately 4,163,000 shares of ZDNet Stock to
certain employees, at a price of $7.50 per share. As a result of the grant
ZDNet has recorded deferred compensation expense of $13,269,000 for the
difference between the exercise price and the deemed fair value of the
underlying shares. This amount has been recorded as a component of division
equity offset by an addition to paid-in capital. ZDNet expects to recognize
non-cash compensation for accounting purposes of $13,269,000 ratably over the
vesting period of the options. These options are currently scheduled to vest
and become exercisable on the fifth anniversary of the date of grant.

  The terms of the options described in the preceding paragraph require an
adjustment in the number of shares of ZDNet Stock that holders may purchase and
the per share purchase price thereof if the initial Number of Shares Issuable
with Respect to ZD's Retained Interest in ZDNet is different from 40,000,000.
This adjustment is similar to the adjustment that would generally be made to
the terms of employee stock options in the event of a stock split. Ziff-Davis
Inc. currently expects that the initial Number of Shares Issuable with Respect
to ZD's Retained Interest in ZDNet will be 70,000,000. Assuming that this is
so, the total number of shares of ZDNet Stock that holders may purchase upon
exercise of these options will increase to approximately 10,026,000 and the per
share purchase price thereof will decrease to approximately $4.29.

  The December 21, 1998 Board actions described above are subject to
stockholder approval. The majority owner of the common stock of Ziff-Davis Inc.
has committed to approve these actions.

  On January 29, 1999, Ziff-Davis Inc. granted options to a number of employees
in connection with the cancellation of corresponding options to purchase stock
of SOFTBANK Corp. In connection with these grants, an affiliate of SOFTBANK
Corp. has agreed with Ziff-Davis Inc. that, if and when any of these options
are exercised, (1) that affiliate will cause the shares of Ziff-Davis Inc.
common stock issuable upon such exercise to be supplied to Ziff-Davis Inc. and
(2) Ziff-Davis Inc. will deliver to that affiliate or its designee the exercise

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

price paid upon such exercise. Thus, the exercise of these options will not
increase the number of shares of Ziff-Davis Inc. common stock outstanding or
Ziff-Davis Inc.'s stockholders' equity. However, ZDNet expects to recognize
compensation expense for accounting purposes of approximately $76,000 over
three years as a result of these grants. As such, this amount has been recorded
in the Financial Statements as additional paid-in capital offset by a reduction
to division equity as deferred compensation.

 GameSpot Inc. 1997 Stock Option Plan

  Ziff-Davis Inc. adopted the GameSpot Inc. 1997 Stock Option Plan (the
"GameSpot Plan") to provide long-term incentives for key employees of GameSpot
and to enhance stockholder value. The GameSpot Plan provides for the grant of
options to purchase shares of GameSpot Inc.'s common stock. GameSpot has
reserved 800,000 shares of GameSpot Inc.'s common stock for issuance under the
GameSpot Plan. Such options vest ratably over 3 years.

  As permitted by SFAS No. 123, ZDNet has 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, 1997
or 1998. Pro forma information regarding net income is required by SFAS No. 123
and has been determined as if ZDNet 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, 1997 and 1998 :

  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, 1997 and 1998, consistent
with the provisions of SFAS No. 123, ZDNet's net loss would have increased by
approximately $156,000, $167,000 and $1,046,000, respectively.

 Employee Stock Purchase Plan

  Ziff-Davis Inc. adopted the Employee Stock Purchase Plan (the "Stock Purchase
Plan") whereby eligible employees may purchase Ziff-Davis Inc.'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 (1) the first business day of a
purchase period or (2) the last business day of a purchase period. Ziff-Davis
Inc. has reserved 1,500,000 shares of common stock for issuance under the Stock
Purchase Plan.

  On December 21, 1998 the Board approved an amendment to the Employee Stock
Purchase Plan, subject to stockholder approval, to permit grants of options
with respect to any series of common stock of Ziff-Davis Inc. and increase the
number of shares available for sale to participants from 1,500,000 shares to
2,500,000 shares.

years ended December 31, 1997 and 1998, respectively.

13. Contingencies

  ZDNet and Ziff-Davis Inc. are subject to various legal proceedings arising
in the normal course of business.

 Class action and derivative litigations

  Following a decline in the price per share of Ziff-Davis Inc.'s common stock
in October 1998, eight securities class action suits were filed against Ziff-
Davis Inc. and certain of its directors and officers in the United States
District Court for the Southern District of New York.

  The complaints allege that defendants violated Sections 11, 12(a) (2) and 15
of the Securities Act of 1933 in connection with the registration statement
filed by Ziff-Davis Inc. with the Securities and Exchange Commission relating
to the initial public offering of the Ziff-Davis Inc.'s common stock on April
29, 1998 (the "IPO"). More particularly, the complaints allege that the
registration statement contained false and misleading statements and failed to
disclose facts that could have indicated an impending decline in Ziff-Davis
Inc.'s revenue. The complaints seek on behalf of a class of purchasers of
Ziff-Davis Inc.'s common stock from the date of the IPO through October 8,
1998 unspecified damages, interest, fees and costs, recission and injunctive
relief such as the imposition of a constructive trust upon the proceeds of the
IPO.

  On January 28, 1999, the court entered an order consolidating the actions,
appointing lead plaintiff's counsel and requiring the filing of a consolidated
amended complaint within 45 days. Thereafter, Ziff-Davis Inc. will have 45
days to respond to the consolidated amended complaint.

  In addition, two derivative suits have been filed by stockholders against
Ziff-Davis Inc. and all of its directors in the Court of Chancery of the State
of Delaware for New Castle County. The complaints allege that the directors
breached their fiduciary duties to Ziff-Davis Inc. by repricing the stock
options awarded to certain directors and demand the nullification of the
repricing and an injunction against exercise by the directors of any repriced
option. Plaintiffs filed an amended complaint on February 17, 1999 (which is
substantially similar to the original complaints, except that the amended
complaint also addresses the granting of "new options" at an allegedly
"reduced exercise price") and have indicated their intent to seek
consolidation of the actions. A response to the amended complaint has not yet
been filed.

 Other legal proceedings

  Ziff-Davis Inc. was named as a defendant in an action, filed on April 17,
1998 in the Supreme Court of the State of New York, by minority stockholders
of SOFTBANK Interactive Marketing Inc. ("SIM"), formerly an indirect
subsidiary of SOFTBANK Corp. The complaint alleges, among other things, that
SBH, SIM's majority stockholder, acting with

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

Ziff-Davis Inc. and two of its senior officers and directors who were directors
of SIM (and who were also named as defendants), had conflicts of interest
between SIM and other Softbank investments (including investments in Ziff-Davis
Inc.) and failed to act in the best interests of SIM and the minority
stockholders by taking actions which benefited Ziff-Davis Inc. The complaint
states claims based on common law fraud, breach of fiduciary duty and aiding
and abetting theories and seeks in excess of $200,000,000 in damages. Ziff-
Davis Inc. and the other defendants have moved to dismiss all of the claims
against them other than a breach of contract claim which is solely against SBH,
and the motion was granted, with the result that all of the claims against
Ziff-Davis Inc. and its officers were dismissed, and most of the claims against
SBH were dismissed, leaving only a claim against SBH concerning the alleged
failure of SBH to give plaintiffs adequate notice of the sale of its stock to
SIM.

  Although the outcome of these cases cannot be predicted, Ziff-Davis Inc.
believes that there are substantial defenses to the claims. Ziff-Davis Inc.
currently cannot estimate its ultimate liability, if any, with respect to such
pending litigations. Accordingly, no provision for such matters has been
included in the financial statements.

14. Subsequent Events

 Incentive Plan

  On March 4, 1999, the Board approved an amendment to the Incentive Plan,
subject to stockholder approval, which increased the number of shares available
for issuance under the Incentive Plan to 23,327,500 shares.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Ziff-Davis Inc.

In our opinion, the accompanying combined balance sheets and the related
combined statements of operations, cash flows and changes in division equity,
present fairly, in all material respects, the financial position of ZD (a
division of Ziff-Davis Inc., the "Company") at December 31, 1997 and 1998, and
the results of its operations and cash flows for each of the three years in the
period ended December 31, 1998, 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 described in Note 1 to the financial statements, ZD is a division of Ziff-
Davis Inc.; accordingly the financial statements of ZD should be read in
conjunction with the audited financial statements of Ziff-Davis Inc.

                     NOTES TO COMBINED FINANCIAL STATEMENTS
 (numbers rounded to the nearest thousand, except share and per share amounts)

1. Organization and Basis of Presentation

 Formation of Ziff-Davis Inc.

  Ziff-Davis Inc. was formed through an initial public offering and
reorganization that were completed on May 4, 1998. (See Note 2.) Prior to that
date, the predecessors of Ziff-Davis Inc. (currently named ZD Inc. and ZD
Events Inc.) were wholly owned indirect subsidiaries of SOFTBANK Corp.
(together with its non-Ziff-Davis Inc. affiliates, "Softbank").

  As further described below, the combined financial statements include the
accounts of ZDI from its date of acquisition (February 29, 1996) and ZD Events.
Effective December 31, 1997, COMDEX and Forums merged and the surviving company
was renamed ZD COMDEX and Forums Inc. ("ZDCF"). In 1998, ZDCF was renamed ZD
Events Inc.

  ZD is the division of Ziff-Davis Inc. (formerly ZD Inc.) focused on the
business of print publishing, trade shows and conferences, market research and
education. ZDNet is the online business division of Ziff-Davis Inc. Each of ZD
and ZDNet is sometimes referred to herein as a "Group".

  In order to prepare separate financial statements for ZD and ZDNet, Ziff-
Davis Inc. has allocated all of its consolidated assets, liabilities, revenue,
expenses and cash flow between ZD and ZDNet. Thus, the financial statements of
ZD and ZDNet, taken together, comprise all of the accounts included in the
corresponding consolidated financial statements of Ziff-Davis Inc.

  ZD's financial statements reflect the application of certain cash management
and allocation policies adopted by the Board of Directors of Ziff-Davis Inc.
(the "Board"). These policies are summarized in Note 5 under "Certain Cash
Management and Allocation Policies".

  Even though Ziff-Davis Inc. has allocated all of its consolidated assets,
liabilities, revenue, expenses and cash flow between ZD and ZDNet, that
allocation and the division of Ziff-Davis Inc. common stock will not change the
legal title to any assets or responsibility for any liabilities and will not
affect the rights of any creditors. Holders of ZD Stock (as defined below) will
continue to be common stockholders of Ziff-Davis Inc. and, as such, will be
subject to all risks associated with an investment in Ziff-Davis Inc. and all
of its businesses, assets and liabilities.

  Financial impacts which occur that affect Ziff-Davis Inc.'s consolidated
results of operations or financial position could affect the results of
operations or financial condition of ZD or the market price of ZD Stock. In
addition, net losses of ZDNet, and any dividends or distributions on, or
repurchases of, ZDNet Stock will reduce the assets of Ziff-Davis Inc. legally
available for dividends on ZD Stock. Accordingly, financial information for ZD

 Relationship with Softbank and MAC

  SOFTBANK Corp. is the indirect majority stockholder of Ziff-Davis Inc.
SOFTBANK Corp. is a Japanese corporation which at the time of the acquisition
of the MAC Assets was majority owned directly and indirectly by its president,
Mr. Son. As of December 31, 1998, Mr. Son owned approximately 45% of SOFTBANK
Corp. (50.2% as of December 31, 1997). MAC, also a Japanese corporation, was
wholly owned by Mr. Son.

 Operations and acquisitions

  ZD operates in two business segments: (1) publishing and (2)events.

 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 U.S. and Europe, although it also licenses or syndicates
its editorial content to over 50 other publications distributed worldwide. The
publishing segment includes a 100% retained interest in ZDNet.

 Events

  The events segment is engaged in the organization, production and management
of trade shows, conferences and seminars for the computer industry. The events
segment's principal operations are in the U.S. 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 $1,800,000,000,
plus transaction costs. Concurrent with the acquisition, in a separate
agreement, MAC, 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 $302,000,000.

  These acquisitions 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 $1,922,000,000 and
$285,000,000, respectively.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


  Subsequent to the acquisition, Holdings and ZDI were merged with ZDI being
the surviving corporation.

 Purchase of the MAC Assets

  In 1997, ZD agreed to purchase certain of the MAC Assets for $370,000,000.
The acquisition was effected in two tranches, the first of which closed on
October 31, 1997 and the second of which closed upon completion of the initial
public offering of Ziff-Davis Inc.'s common stock (further described below). At
December 31, 1997, ZD had accrued the $370,000,000 purchase price which was
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 were under common
control at the time of the acquisitions. 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 ZD
includes ZDI, ZD Events and the MAC Assets (including ZD's 100% retained
interest in ZDNet) from February 29, 1996.

 Acquisition of Sendai

  On May 8, 1996, ZD 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 $27,500,000, 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
$33,378,000. 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 Sky TV

  On October 28, 1998, ZD acquired the assets of Sky TV Inc. and certain
affiliates for approximately $12,150,000 in cash plus contingent payments
related to earnings performance payable in 2002. Sky TV is a media company that
provides video content for distribution principally through airline in-flight,
cable and broadcast television. The acquisition was accounted for as a purchase
and accordingly, Sky TV's results are included in the combined financial
statements since the date of acquisition. The excess of the purchase price over
assets acquired approximated $11,318,000. The operations of Sky TV did not have
a material effect on the combined results of operations for the year ended
December 31, 1998.

2. Reorganization and Initial Public Offering

  On February 4, 1998, a nonstock corporation, ZD Inc., was formed in
contemplation of a reorganization and initial public offering of Ziff-Davis
Inc. Upon completion of the initial public offering (described below), Ziff-
Davis Inc. was renamed ZD Inc, ZDCF was renamed ZD Events Inc. and ZD Inc. was
renamed Ziff-Davis Inc.

  On May 4, 1998, SOFTBANK Corp., through its wholly owned subsidiary SOFTBANK
Holdings Inc. ("SBH"), completed a reorganization whereby the common stock of
ZD Inc. and ZD Events Inc. were contributed to Ziff-Davis Inc. in exchange for
73,619,355 shares of Ziff-Davis Inc.'s common stock. Concurrent with the
reorganization, Ziff-Davis Inc. (1) completed an initial public offering of
25,800,000 common shares at an initial public offering price of $15.50 per
share, (2) issued $250,000,000 of 8 1/2% subordinated notes due 2008, (3)
entered into a $1,350,000,000 credit facility with a group of banks under which
$1,250,000,000 was borrowed and (4) converted $908,673,000 of intercompany
indebtedness to equity. In addition, Ziff-Davis Inc. received approximately
$9,107,000 of fixed assets from Kingston Technology Company ("Kingston"), a
related party, in exchange for 580,645 shares of Ziff-Davis Inc.'s common stock
and $107,000 in cash. These assets have been subsequently leased back to
Kingston. Total shares of common stock issued to Softbank were 74,200,000. The
transactions described above are herein referred to as the "Reorganization".

  Proceeds, net of transaction costs, from the initial public offering and
funding transactions in the Reorganization of $1,863,260,000 were used to
complete the purchase of certain assets from MAC for $370,000,000, and repay
intercompany indebtedness.

  On May 28, 1998, Ziff-Davis Inc.'s U.S. underwriters exercised their option
to purchase 2.0 million additional shares of common stock to cover over-
allotments. ZD purchased the additional shares from SBH resulting in no change
to the total number of shares outstanding. On December 31, 1998, SBH
contributed 71,619,355 shares of Ziff-Davis Inc.'s common stock to SOFTBANK
America Inc., an affiliate of SOFTBANK Corp.

reduction of interest expense, a $900,000 increase in depreciation expense and
a $900,000 reduction of selling, general and administrative expenses, as well
as the tax effect of these items recorded at an effective tax rate of 40%.

3. ZDNet Stock Proposal (unaudited)

  The stockholders of Ziff-Davis Inc. are scheduled to vote on a proposal (the
"Tracking Stock Proposal") to authorize the issuance of a new series of common
stock, to be designated as Ziff-Davis Inc.--ZDNet Common Stock ("ZDNet Stock"),
intended to reflect the performance of Ziff-Davis Inc.'s online business
division ("ZDNet"). The majority owner of the common stock of Ziff-Davis Inc.
has committed to vote for the Tracking Stock Proposal. Before the ZDNet Stock
is first issued, Ziff-Davis Inc.'s existing common stock will be re-classified
as Ziff-Davis Inc.--ZD Common Stock ("ZD Stock") and that stock will be
intended to reflect the performance of Ziff-Davis Inc.'s other businesses and a
"Retained Interest" in ZDNet (i.e., Ziff-Davis Inc.'s interest in ZDNet
excluding the interest intended to be represented by outstanding shares of
ZDNet Stock) (collectively, "ZD").

  ZD currently has a 100% Retained Interest in ZDNet. Following approval of the
Tracking Stock Proposal, Ziff-Davis Inc. currently plans to offer to the
public, for cash, 10,000,000 shares of ZDNet Stock intended to represent
approximately 14% of the equity value attributed to ZDNet. Ziff-Davis Inc.
expects to offer ZDNet Stock to the public sometime in the first or second
quarter of 1999. However, Ziff-Davis Inc. could choose to conduct the offering
at a later time, or not to make the offering at all, depending on the
circumstances at the time. In addition to or instead of the offering, Ziff-
Davis Inc. reserves the right to distribute ZDNet Stock to stockholders of
Ziff-Davis Inc.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


  The book value associated with ZD's Retained Interest in ZDNet will be
increased proportionately for net income (or decreased proportionately for net
loss) of ZDNet. In addition, that book value will be adjusted from time to time
as set forth below.

  Currently, Ziff-Davis Inc. provides all funding for ZD and ZDNet as described
in Note 5 under "Certain Cash Management and Allocation Policies". Ziff-Davis
Inc. intends to continue these practices until ZDNet Stock is first issued.
Accordingly, no interest income or expense from or to ZDNet has been reflected
in the financial statements of ZD for any period prior to the date on which
ZDNet Stock is first issued.

  After the date on which ZDNet Stock is first issued, for financial statement
purposes, the following policies will apply except to the extent the Board
rescinds, modifies or adds to them:

    (a) Ziff-Davis Inc. will attribute each future incurrence or issuance of
  external debt or preferred stock (and the proceeds thereof) to ZD, except
  in cases where the Board determines otherwise. The Board may determine from
  time to time to attribute an incurrence or issuance of debt or preferred
  stock (and the proceeds thereof) to ZDNet to the extent that Ziff-Davis
  Inc. incurs or issues the debt or preferred stock for the benefit of ZDNet,
  but the Board will not be required to do so.

    (b) Ziff-Davis Inc. will attribute each future issuance of ZD Stock (and
  the proceeds thereof) to ZD. Ziff-Davis Inc. may attribute any future
  issuance of ZDNet Stock (and the proceeds thereof) to ZD in respect of its
  Retained Interest in ZDNet (in a manner analogous to a secondary offering
  of common stock of a subsidiary owned by a corporate parent) or to ZDNet
  (in a manner analogous to a primary offering of common stock). Dividends on
  and repurchases of ZD Stock will be charged against ZD, and dividends on
  and repurchases of ZDNet Stock will be charged against ZDNet. In addition,
  at the time of any dividend on ZDNet Stock, Ziff-Davis Inc. will credit to
  ZD, and charge against ZDNet, a corresponding amount in respect of ZD's
  Retained Interest in ZDNet.

    (c) Whenever ZDNet holds cash (other than cash of ZDNet's foreign
  operations or cash of ZDNet's operations that are not wholly owned), ZDNet
  will normally transfer that cash to ZD. Conversely, whenever ZDNet has a
  cash need (other than cash needs of ZDNet's foreign operations or cash
  needs of ZDNet's operations that are not wholly owned), ZD will normally
  fund that cash need. However, the Board will determine, in its sole
  discretion, whether to provide any particular funds to either Group. The
  Board is not obligated to cause either Group to provide funds to the other
  Group if the Board determines it is not in the best interest of Ziff-Davis
  Inc. to do so.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


    (d) Ziff-Davis Inc. will account for all cash transfers from one Group to
  or for the account of the other Group (other than transfers in return for
  assets or services rendered or transfers in respect of ZD's Retained
  Interest that correspond to dividends paid on ZDNet Stock) as inter-Group
  revolving credit advances unless (1) the Board determines that a given
  transfer (or type of transfer) should be accounted for as a long-term loan,
  (2) the Board determines that a given transfer (or type of transfer) should
  be accounted for as a capital contribution increasing ZD's Retained
  Interest in ZDNet or (3) the Board determines that a given transfer (or
  type of transfer) should be accounted for as a return of capital reducing
  ZD's Retained Interest in ZDNet. There are no specific criteria to
  determine when Ziff-Davis Inc. will account for a cash transfer as a long-
  term loan, a capital contribution or a return of capital rather than
  an inter-Group revolving credit advance. The Board would make such a
  determination in the exercise of its business judgment at the time of such
  transfer (or the first of such type of transfer) based upon all relevant
  circumstances. Factors the Board would consider include (1) the current and
  projected capital structure of each Group, (2) the relative levels of
  internally generated funds of each Group, (3) the financing needs and
  objectives of the recipient Group, (4) the investment objectives of the
  transferring Group, (5) the availability, cost and time associated with
  alternative financing sources and (6) prevailing interest rates and general
  economic conditions.

    (e) Any cash transfer accounted for as an inter-Group revolving credit
  advance will bear interest at the rate at which Ziff-Davis Inc. could
  borrow such funds on a revolving credit basis (as the Board determines in
  its sole discretion). Any cash transfer accounted for as a long-term loan
  will have interest rate, amortization, maturity, redemption and other terms
  that generally reflect the then prevailing terms on which Ziff-Davis Inc.
  could borrow such funds (as the Board determines in its sole discretion).

    (f) Any cash transfer from ZD to ZDNet (or for its account) accounted for
  as a capital contribution will correspondingly increase ZDNet's division
  equity and ZD's Retained Interest in ZDNet. As a result, the number of
  shares of ZDNet Stock that could be issued by Ziff-Davis Inc. for the
  account of ZD in respect of its Retained Interest in ZDNet (the "Number of
  Shares Issuable with Respect to ZD's Retained Interest in ZDNet") will
  increase by (1) the amount of such capital contribution divided by (2) the
  Market Value of ZDNet Stock on the date of transfer.

    (g) Any cash transfer from ZDNet to ZD (or for its account) accounted for
  as a return of capital will correspondingly reduce ZDNet's division equity
  and ZD's Retained Interest in ZDNet. As a result, the Number of Shares
  Issuable with Respect to ZD's Retained Interest in ZDNet will decrease by
  (1) the amount of such return of capital divided by (2) the Market Value of
  ZDNet Stock on the date of transfer.

4. Summary of Significant Accounting Policies

 Principles of combination

  The combined financial statements include the accounts of ZD. All significant
transactions within the ZD division have been eliminated in combination.

  Investments in companies in which ZD's ownership interests range from 20% to
50% and in which ZD has the ability to exercise significant influence over the
operating and financial policies of such companies are accounted for under the
equity method.

 Cash and cash equivalents

  ZD considers all highly liquid investments with an original maturity of 3
months or less to be cash equivalents.

 Concentration of credit risk

  ZD places its temporary cash investments with high credit quality financial
institutions. At times, such investments may be in excess of federally insured
limits. ZD has not experienced losses in such accounts.

  ZD's advertisers and exhibitors include principally customers who represent a
variety of technology companies in the U.S. and other countries. ZD extends
credit to its customers and distributors 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 cost or estimated fair value at
the date of acquisition. Depreciation is computed using the straight-line
method, half-year convention, over the estimated useful lives of the assets
which range from 3 to 30 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.

                                      F-45

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


 Investment in ZDNet

  ZD's Retained Interest in 100% of the division equity of ZDNet is reflected
as "Retained Interest in ZDNet" in ZD's balance sheets. Similarly, ZD's
Retained Interest in 100% of the division net losses of ZDNet is reflected as
"Net loss related to retained interest in ZDNet" in ZD's combined statements of
operations.

  Ziff-Davis Inc. accounts for ZD's retained interest in ZDNet in a manner
similar to the method prescribed under APB No. 18, The Equity Method of
Accounting for Investments in Common Stock.

 Debt issuance costs and discount on senior subordinated notes

  The cost to issue debt is recorded in the balance sheet in other assets and
amortized to interest expense over the life of the debt. The discount on the
senior subordinated notes is recorded in the balance sheet as a reduction of
long-term debt and is amortized to interest expense over the life of the notes.
All amounts are amortized using the effective-interest method.

 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 estimated useful lives.
Identifiable 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. (See Note 9.) ZD assesses the recoverability of 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 value of assets, an
impairment loss is recognized to reduce the carrying value of the intangibles
to estimated recoverable value.

 Revenue recognition

  Advertising revenue for ZD's 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

<PAGE>

                                       ZD

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

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.

 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.

 Reportable segments

  In 1998, ZD adopted Statement of Financial Accounting Standards ("SFAS") No.
131, Disclosures about Segments of an Enterprise and Related Information. SFAS
No. 131 supersedes SFAS No. 14, Financial Reporting for Segments of a Business
Enterprise, replacing the "industry segment" approach with the "management"
approach. The management approach designates the internal organization that is
used by management for making operating decisions and assessing performance as
the source of ZD's reportable segments. SFAS No. 131 also requires disclosures
about products and services, geographic areas and major customers. The adoption
of SFAS No. 131 did not affect results of operations or financial position but
did affect the disclosure of segment information. (See Note 21.)

 Foreign currency

  The effect of translating foreign currency financial statements into U.S.
dollars is included in the cumulative translation adjustments account in
division equity. Gains and losses on foreign currency transactions, which are
not significant to operations, have been included in selling, general and
administrative expenses. Ziff-Davis Inc. has not historically entered into
forward currency contracts.

 (numbers rounded to the nearest thousand, except share and per share amounts)


 Other non-operating income

  Other non-operating income includes management fee income and ZD's equity
share of income or loss from joint ventures.

 Income taxes

  ZD 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

  ZD's financial instruments recorded on the balance sheet include cash and
cash equivalents, accounts receivable, accounts payable and debt. Because of
their short maturity, the carrying amount of cash and cash equivalents,
accounts receivable and accounts payable approximate fair value. Fair value of
long-term bank debt is based on rates available to ZD for debt with similar
terms and maturities. Fair value of public debt is based on market prices.

  ZD uses interest rate swap agreements to manage risk on its floating rate
debt portfolio. Fair value of these instruments is based on estimated current
settlement cost.

Interest rate swaps

  ZD periodically uses interest rate swaps to manage its exposure to interest
rate fluctuations on its floating rate debt. These interest rate swaps are
entered into for hedging purposes and, as such, must be designated and
effective as a hedge against the risk of increased interest rates. Under the
terms of the agreements ZD pays a fixed interest rate on a notional amount and
receives a variable interest rate on the same notional amount. The differential
between amounts paid and received is recorded as additional interest expense.
Interest rate swaps designated but no longer effective as a hedge would be
reported at market value and the related gains and losses would be recognized
in earnings. Gains or losses on termination of interest rate swaps would be
recognized in earnings in the period of termination.

 Stock-based compensation

  ZD has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees ("APB 25"), to account for stock
options. Effective January 1, 1996, ZD adopted the disclosure-only provisions
of Statement of Financial Accounting Standard ("SFAS") No. 123, Accounting for
Stock-Based Compensation.

 Comprehensive income

  ZD implemented SFAS No. 130, Reporting Comprehensive Income, effective
January 1, 1998. This standard requires ZD to report the total changes in
division equity that do not result directly from transactions with
stockholders, including those which do not affect retained earnings. These
changes are not material to ZD's combined financial statements.

 New accounting pronouncement

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133
establishes accounting and reporting standards for derivative instruments and
for hedging activities and is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. ZD does not expect that the adoption of SFAS No.
133 will have a material impact on ZD's results of operations. ZD will adopt
SFAS No.133 beginning with its 2000 financial statements.

 Reclassifications

  Certain amounts have been reclassified, where appropriate, to conform to the
current financial statement presentation.

5. Certain Cash Management and Allocation Policies

  ZD's financial statements reflect the application of certain cash management
and allocation policies summarized below. The Board may rescind, modify or add
to any of these policies.

 Treasury activities

  Ziff-Davis Inc. manages most treasury activities on a centralized,
consolidated basis. These activities include the investment of surplus cash,
the issuance, repayment and repurchase of short-term and long-term debt, and
the issuance and repurchase of common stock and preferred stock. Each of ZD and
ZDNet generally remits its cash receipts (other than receipts of foreign
operations or operations that are not wholly owned) to Ziff-Davis

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

Inc., and Ziff-Davis Inc. generally funds ZD's and ZDNet's cash disbursements
(other than disbursements of foreign operations or operations that are not
wholly owned), on a daily basis.

  In the financial statements of ZD and ZDNet, (1) all external debt and equity
transactions (and the proceeds thereof) were attributed to ZD, (2) whenever
ZDNet held cash (other than cash of ZDNet's foreign operations or cash of
ZDNet's operations that are not wholly owned), that cash was transferred to ZD
and accounted for as a return of capital (i.e., as a reduction in ZDNet's
division equity and ZD's Retained Interest in ZDNet) and (3) whenever ZDNet had
a cash need (other than cash needs of ZDNet's foreign operations or cash needs
of ZDNet's operations that are not wholly owned), that cash need was funded by
ZD and accounted for as a capital contribution (i.e., as an increase in ZDNet's
division equity and ZD's Retained Interest in ZDNet).

 Corporate general and administrative expenses

  Ziff-Davis Inc. allocates the cost of certain corporate general and
administrative services and shared services (including certain legal,
accounting (tax and financial), information systems, telecommunications,
purchasing, marketing, intellectual property, public relations, corporate
office and travel expenses) (collectively, "Central Services") to ZD based on
utilization. Where determinations based on utilization alone are impracticable,
Ziff-Davis Inc. uses other methods and criteria that management believes to be
equitable and to provide a reasonable estimate of the cost attributable to ZD.

 Taxes

  Federal income taxes, which are determined on a consolidated basis, are
allocated to ZD (and reflected in its financial statements) in accordance with
Ziff-Davis Inc.'s tax allocation policy. In general, this policy provides that
the consolidated tax provision (and related tax payments or refunds) are
allocated between the Groups based principally upon the financial income,
taxable income, credits and other amounts directly related to the respective
Groups. Tax benefits that cannot be used by the Group generating such
attributes, but can be utilized on a consolidated basis, are allocated to the
Group that generated such benefits. As a result, the allocated Group amounts of
taxes payable or refundable are not necessarily comparable to those that would
have resulted if the Groups had filed separate tax returns. State income taxes
generally are computed on a separate company basis.

 Royalty charges

  ZD charges ZDNet an annual fee for the use of various brands and editorial
content. The current annual fee, which is reflected in ZD's financial
statements as a reduction of its

selling, general and administrative costs, is equal to 5% of the first
$100,000,000 of ZDNet's revenue for the year, 4% of the next $50,000,000 of
ZDNet's revenue for that year and 3% of any incremental revenue over
$150,000,000 for that year. The Board may at some point in the future change
this fee as it, in its sole discretion, deems appropriate in light of the
circumstances from time to time.

6. Restructuring

  Margin pressure on computer equipment manufacturers, industry and product
delays, lower demand in Asia and a focus on the Year 2000 transition are
contributing to a reduced demand for advertising in ZD's magazines, principally
PC Magazine, PC/Computing, Computer Shopper and PC Week. ZD believes these
factors are continuing.

  As a result of this reduced demand, in October 1998 Ziff-Davis Inc. announced
a restructuring program with the intent of significantly reducing its cost
base. Ziff-Davis Inc. incurred a pre-tax charge of $52,239,000 for this
restructuring program. The charge included asset impairment costs
($37,890,000), employee termination costs ($8,668,000) and costs to exit
activities ($5,681,000) principally resulting from the closing of three
publications (Windows Pro, Internet Business and Equip), and the reduction of
Ziff-Davis Inc.'s work force by 310 employees. The charge also included costs
resulting from the discontinuation of certain educational journals and trade
shows. The following sets forth additional detail concerning the principal
components of the charge:

  . Asset impairment costs totaled $37,890,000. These costs, which are non-
    cash, included the write-off of intangible assets, primarily subscriber
    lists, advertising lists, tradenames and goodwill, associated with the
    discontinued publications ($34,245,000) and trade shows ($2,930,000) as
    well as deferred marketing expenses associated with the discontinued
    educational journals ($715,000).

  . Employee termination costs related to severed personnel at the closed
    publications as well as a rationalization and resulting workforce
    reduction of the remainder of
   Ziff-Davis Inc.'s operations. Employee termination costs included payments
   for severance and earned vacation as well as the costs of outplacement
   services and the provision of continued benefits to personnel. As of
   December 31, 1998, $5,200,000 of the $8,668,000 related to these employee
   terminations had been paid.

  . Costs to exit activities reflect the costs associated with the final
    closure of the discontinued publications ($1,837,000) and the costs to
    reduce office space under lease as a result of the reduced level of
    employees ($3,844,000).

  Included in accrued expenses is $7,260,000 related to this restructuring
which Ziff-Davis Inc. believes will be paid during the first half of 1999.

  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, the purchase price of these
acquisitions 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 estimated fair value as determined by an income approach. Trademarks/trade
names were recorded at estimated fair value using a relief from royalty
approach.

  All intangible assets are being amortized using the straight-line method over
estimated useful lives, up to 40 years. In determining the estimated useful
lives, ZD considered its competitive position in the markets in which it
operates, 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. In connection with the restructuring described in Note 6, ZD
recorded a $37,175,000 write-down of intangible assets associated with
discontinued publications and events.

12. Income Taxes

  Provision (benefit) for income taxes and related assets and liabilities
attributed to ZD are determined in accordance with Ziff-Davis Inc.'s tax
allocation policy. (See Note 5.)

  Prior to the Reorganization and initial public offering described in Note 2,
ZD had 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
consolidated statements of operations and tax liabilities reflected in the
combined balance sheet have been prepared on a separate return basis as though
ZD 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 Ziff-
Davis Inc. Following the Reorganization, Ziff-Davis Inc. will no longer be
included in the consolidated U.S. federal income tax returns filed by Softbank.

  Income (loss) before income taxes is attributable to the following
jurisdictions:

</TABLE>

  The effective tax rate differs from the federal statutory tax rate primarily
as a result of ZD's inability to deduct losses of the MAC Assets prior to May
4, 1998, and ZD's policy of recording the losses related to its 100% retained
interest in ZDNet on a net of tax basis. The amortization of non-deductible
goodwill resulted primarily from the acquisition of 100% of the stock of
Holdings in 1996.

</TABLE>

  As of December 31, 1997 and 1998 ZD had total deferred tax assets of
$112,351,000 and $99,959,000 respectively, and total deferred tax liabilities
of $289,239,000 and $247,832,000 respectively. The December 31, 1997 and 1998
net deferred tax assets are reduced by a valuation allowance of $35,261,000 and
$30,741,000 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 1998 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, inasmuch as
such losses will not be available to ZD.

  At December 31, 1998, ZD has U.S. and foreign net operating loss
carryforwards of approximately $172,943,000, which will begin to expire in
1999. ZD's utilization of certain net operating loss carryforwards, of
approximately $112,549,000, is subject to limitations, due to the change of
ownership resulting from the Softbank acquisition of the Holdings stock on
February 29, 1996. Management believes that such limitations will not
significantly affect ZD's 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, ZD
has alternative minimum tax credit carryforwards of $385,000 which may be
carried forward indefinitely until used.

  Undistributed earnings of foreign subsidiaries for which no deferred taxes
have been provided approximated $2,789,000 at December 31, 1998. Any additional
U.S. taxes payable on these foreign earnings, if remitted, would be
substantially offset by credits for foreign taxes already paid.

 8 1/2% senior subordinated notes

  On May 4, 1998 ZD issued 8 1/2% Senior Subordinated Notes due 2008 (the
"Notes") in the aggregate principal amount of $250,000,000. The Notes were
issued at a discount of $915,000 which is being amortized to interest expense
over the term of the Notes. Included in the balance sheet as a reduction of
long-term debt at December 31, 1998 is $870,000 representing the unamortized
discount on the Notes. Interest on the Notes is payable semi-annually on May 1
and November 1 of each year. Redemption of the Notes by ZD is subject to
certain limitations. The Notes are subordinated to all existing and future
senior indebtedness.

 Credit facility

  Ziff-Davis Inc. is party to a secured guaranteed credit agreement with The
Bank of New York, Morgan Stanley Senior Funding, DLJ Capital Funding and The
Chase Manhattan Bank, as agents, to provide a $1,350,000,000 term credit
facility. The amount outstanding under this facility at December 31, 1998 was
$1,220,000,000. The credit facility consists of: (1) a seven-year $400,000,000
reducing revolving credit facility, with $270,000,000 drawn

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

as of December 31, 1998; (2) a seven-year $450,000,000 term loan ("Term Loan
A"); and (3) an eight-year $500,000,000 term loan ("Term Loan B"). Under the
credit facility, Ziff-Davis Inc. paid interest at rates ranging from LIBOR plus
1.5% to LIBOR plus 1.75%. See "--Amendment to credit facility" below.

There are various customary conditions to draw-downs under the revolving
commitments. The revolving credit commitments will be reduced and the $450
million Term Loan A will be amortized, beginning in September 2000, by:

  . 10% in 2000, in two equal quarterly installments,

  . 20% in each of 2001, 2002, 2003 and 2004 in four equal quarterly
    installments and

  . 10% at final maturity in March 2005.

The $500 million term loan will be amortized, beginning in September 2000, by:

  . $2 million in 2000, in two equal quarterly installments,

  . $4 million in each of 2001, 2002, 2003, 2004 and 2005 in four equal
    quarterly installments and

  . $478 million at final maturity in March 2006.


  The Notes and the credit facility are secured, in part, by a first priority
security interest in capital stock of certain subsidiaries of Ziff-Davis Inc.
and are guaranteed by certain wholly owned domestic subsidiaries of Ziff-Davis
Inc., in each case, including ZD Inc. and ZD Events.

  Under its most restrictive covenant, ZD could have borrowed an additional
$28,800,000 under the credit facility at December 31, 1998.

 Covenants

  The Notes and the credit facility contain certain customary affirmative and
negative covenants, including covenants with respect to limitations on
dispositions of assets, changes of business and ownership, mergers or
acquisitions, restricted payments, indebtedness, loans and investments and
transactions with affiliates. The Notes and the credit facility also contain
certain financial covenants including levels of debt to EBITDA and EBITDA to
interest ratios.

  The failure to satisfy any of the covenants would constitute an event of
default under the credit facility. The credit facility also includes 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. At December 31, 1998, management believes that ZD was in compliance
with all covenants under its debt agreements.

 Amendment to credit facility

  On December 16, 1998, the lenders on Ziff-Davis Inc.'s $1,350,000,000 credit
facility agreed to amend certain provisions of that facility. The amended
provisions include an increase in allowed leverage ratios. In return, Ziff-
Davis Inc. agreed to pay a one-time fee of $3,375,000 and increase rates on
amounts borrowed under the facility to rates ranging from LIBOR plus 2.875% to
LIBOR plus 3.375%, depending on the type of loan. The fee has been capitalized
and will be amortized to interest expense over the remaining term of the
facility.

 Related-party debt

  In March 1995, Ziff-Davis Inc. entered into a $100,000,000 note payable to
Softbank due in quarterly installments, maturing on February 28, 2010 and
bearing interest at 9.9% per annum. (See Note 14.)

 Interest rate swaps

  On June 10, 1998 ZD entered into interest rate swap agreements, with an
aggregate notional amount of $550,000,000. Under these swap agreements, which
took effect on August 10, 1998, ZD receives a floating rate of interest based
on three-month LIBOR, which resets quarterly, and ZD pays a fixed rate of
interest, each quarter, for the terms of the

 (numbers rounded to the nearest thousand, except share and per share amounts)

respective agreements. The terms of these agreements range from 3 to 7 years
and the weighted average fixed rate ZD pays is 5.85%. ZD has entered into these
agreements solely to hedge its interest rate risk under its floating rate bank
debt.

  For the year ended December 31, 1998, these interest rate swaps did not have
a material impact on the financial statements.

14. Related Party Transactions

  ZD transacts business with a group of companies affiliated through common
ownership with Softbank, and has various transactions and relationships with
members of the group. Due to 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.

  As part of the 1996 acquisition of ZDI, ZD agreed to assume certain
obligations to management arising out of prior employment arrangements with
previous owners. In January 1997, ZD paid all amounts due, including accrued
interest, through the payment date.

  Prior to the Reorganization and initial public offering, ZD was a member of
Softbank's central cash management system. Under this system, ZD would
periodically transfer excess cash to Softbank for cash management purposes and
in turn receive cash advances from Softbank to fund ZD's short-term working
capital requirements. Interest was accrued based on the net balance outstanding
at the end of each month. Interest income was earned at the 30-day LIBOR rate
for the applicable month. Interest expense was incurred at the 30-day LIBOR
rate plus 0.5%.

  As a result of contingent purchase price adjustments related to its
acquisition of Inter@ctive Enterprises, ZD is obligated to pay the prior owners
of Inter@ctive Week $10,850,000 which was recorded as an increase to intangible
assets. The purchase price payments of $950,000, $4,500,000 and $5,400,000 are
due in 1998, 1999 and 2000, respectively. The 1999 and 2000 payments have been
classified as current and long-term due to management.

 Other affiliated arrangements

  During the years ended December 31, 1996, 1997 and 1998, ZD incurred
$2,000,000, $1,631,000 and $169,000, respectively, in advertising expense with
Yahoo!, Inc. (Yahoo!), an affiliated company.

  ZD sells advertising space and exhibition services to Kingston. During the
years ended December 31, 1996, 1997 and 1998, ZD recorded revenue of $882,000,
$2,667,000 and $2,472,000, respectively, from sales to Kingston. These services
were provided under terms consistent with those provided to unaffiliated
customers.

  In addition, on May 4, 1998 Ziff-Davis Inc. purchased $9,107,000 of fixed
assets from Kingston in exchange for cash and common stock of Ziff-Davis Inc.
Such fixed assets were subsequently leased back to Kingston. Rental income
included as a reduction of selling, general and administrative expenses
relating to this transaction was $2,400,000 in 1998.

  ZD has entered into an agreement to manage certain trade shows and
expositions owned by Softbank, whereby ZD earns management, royalty and
licensing fees. The fees earned by ZD for the years ended December 31, 1996,
1997 and 1998 were $3,394,000, $4,057,000 and $1,117,000, respectively.

  ZD has an arrangement with SOFTBANK Services, an affiliated company, whereby
ZD is charged for administrative services provided plus a management fee. For
the years ended December 31, 1996, 1997 and 1998 ZD incurred services fees of
$359,000, $1,259,000 and $810,000, respectively, in relation to this agreement.
During 1998, SOFTBANK Services was sold to an unrelated third party and the
arrangement was terminated.

  ZD has entered into certain licensing agreements with Softbank for the
publishing and distribution of Japanese language editions of certain
publications. The fees earned by ZD for the years ended December 31, 1996, 1997
and 1998 were approximately $964,000, $1,818,000 and $709,000, respectively.

  Certain ZD employees have been granted options to purchase SOFTBANK Corp.
common stock (the "Softbank Options"). Further, on January 29, 1999, options to
purchase Ziff-Davis Inc. common stock were granted in connection with the
cancellation of certain Softbank Options. (See Note 15.)

  Included in selling, general and administrative expenses is an allocation for
Ziff-Davis Inc.'s Central Services amounting to $61,359,000, $85,739,000 and
$92,032,000 for the years ended December 31, 1996, 1997 and 1998, respectively.
Also included as a reduction in selling, general and administrative expenses is
a royalty charge from ZDNet amounting to $811,000, $1,611,000 and $2,807,000
for the years ended December 31, 1996, 1997 and 1998, respectively. (See Note
5.)

  ZD's publications sell advertising to ZDNet at discounts to market rates. Had
ZD charged market rates for such advertising, ZD's revenue would have increased
by $2,235,000, $2,671,000 and $1,429,000 for the years ended December 31, 1996,
1997 and 1998, respectively.

  In July 1997, Ziff-Davis Inc. entered into a license and services agreement
to develop ZDTV for MAC Holdings (America) Inc. ("MHA"), a company that is
wholly owned by Mr. Masayoshi Son, who is a director of Ziff-Davis Inc. and
principal stockholder of SOFTBANK Corp. Under this agreement, Ziff-Davis Inc.
agreed to fund ZDTV's operations through unsecured advances and was granted an
option to purchase ZDTV for a price equal to MHA's investment plus 10% per
annum for the period of investment. The cumulative advances, which through
December 31, 1997, totaled $14.4 million net of $10.1 million in repayments
were repaid concurrently with the Reorganization. Advances in 1998 totaled
$48.6 million and were repaid upon completion of Ziff-Davis Inc.'s acquisition
of ZDTV. (See Notes 2 and 23.)

  Ziff-Davis Inc. 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 $1,161,000
through 2003.

above notes payable.

 Guarantee of Softbank's U.S. debt

  In April 1996, Softbank signed a line of credit agreement totaling
$50,000,000 with an independent lender for which ZD, along with certain other
SOFTBANK Corp. affiliates, is a guarantor. In January 1997, October 1997 and
March 1998, this line of credit was increased to $75,000,000, $150,000,000 and
$450,000,000, respectively. On May 4, 1998, ZD was released from this
guarantee.

 Return of capital and dividends

  On December 15, 1996, ZD declared a return of capital of approximately
$900,000,000 paid through the issuance of a note payable to a subsidiary of

15. Stock Compensation Plans

 SOFTBANK Executive Stock Option Plans

  The Softbank Executive Stock Option Plans provide for the granting of
nonqualified stock options (the "Softbank Options") to purchase the common
stock of SOFTBANK Corp. to officers, directors and key employees of ZD.
SOFTBANK Corp. is a publicly traded company in Japan. 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, 1998, 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. On January 19,
1998, the exercise price of all of the shares outstanding under option
agreements was reset to (Yen)4,000, 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 could only be
exercised after July 19, 1998. The repricing of the stock options did not
result in compensation expense to ZD.

 1998 Incentive Compensation Plan and the 1998 Non-Employee Directors' Stock
Option Plan

  In 1998, Ziff-Davis Inc. adopted the 1998 Incentive Compensation Plan (the
"Incentive Plan") and the 1998 Non-Employee Directors' Stock Option Plan (the
"Non-Employee Directors' Plan"). The Incentive Plan provides for the grant of
options, stock appreciation rights, stock awards and other interests in Ziff-
Davis Inc.'s common stock to key employees of Ziff-Davis Inc. and its
affiliates and consultants. The Non-Employee Directors' Plan provides for the
grant of stock options to non-employee directors. Ziff-Davis Inc. has reserved
8,500,000 shares of common stock for issuance under the Incentive Plan and
200,000 shares of common stock for issuance under the Non-Employee Directors'
Plan. During 1998, Ziff-Davis Inc. granted options to purchase 6,418,495 shares
with exercise prices ranging from $6.00 to $16.00 per share representing the
fair value of such options on the date of grant. Such options vest ratably over
five years.

  On September 23, 1998, the Board approved the reduction of the exercise price
of all options outstanding under the Incentive Plan from $16.00 to $6.00, the
closing market price of Ziff-Davis Inc.'s common stock on that date. In
addition, the vesting period of the options was extended by three months. The
repricing did not result in compensation expense to ZD.

  On December 21, 1998 the Board approved an amendment to the Incentive Plan to
permit grants of options and other stock-based awards with respect to any
series of common stock of Ziff-Davis Inc. and to increase the number of shares
available for issuance from 8,500,000 shares to 17,827,500 shares.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


  In addition, on December 21, 1998, the Board approved the grant of options to
acquire an aggregate of approximately 1,566,000 shares of ZDNet Stock to
certain employees at a price of $7.50 per share. As a result of the grant ZD
has recorded deferred compensation expense of $4,993,000 for the difference
between the exercise price and the deemed fair value of the underlying shares.
This amount has been recorded as a component of division equity offset by an
addition to paid-in capital. ZD expects to recognize non-cash compensation for
accounting purposes of $4,993,000 ratably over the vesting period of the
options. These options are currently scheduled to vest and become exercisable
on the fifth anniversary of the date of grant.

  The terms of the options described in the preceding paragraph require an
adjustment in the number of shares of ZDNet Stock that holders may purchase and
the per share purchase price thereof if the initial Number of Shares Issuable
with Respect to ZD's Retained Interest in ZDNet is different from 40,000,000.
This adjustment is similar to the adjustment that would generally be made to
the terms of employee stock options in the event of a stock split. Ziff-Davis
Inc. currently expects that the initial Number of Shares Issuable with Respect
to ZD's Retained Interest in ZDNet will be 70,000,000. Assuming that this is
so, the total number of shares of ZDNet Stock that holders may purchase upon
exercise of these options will increase to approximately 10,200,000 and the per
share purchase price thereof will decrease to approximately $4.29.

  The December 21, 1998 Board actions described above are subject to
stockholder approval. The majority owner of the common stock of Ziff-Davis Inc.
has committed to approve these actions.

  On January 29, 1999, Ziff-Davis Inc. granted options to a number of employees
in connection with the cancellation of corresponding options to purchase stock
of SOFTBANK Corp. In connection with these grants, an affiliate of SOFTBANK
Corp. has agreed with Ziff-Davis Inc. that, if and when any of these options
are exercised, (1) that affiliate will cause the shares of Ziff-Davis Inc.
common stock issuable upon such exercise to be supplied to Ziff-Davis Inc. and
(2) Ziff-Davis Inc. will deliver to that affiliate or its designee the exercise
price paid upon such exercise. Thus, the exercise of these options will not
increase the number of shares of Ziff-Davis Inc. common stock outstanding or
Ziff-Davis Inc.'s stockholders' equity. However, ZD expects to recognize
compensation expense for accounting purposes of approximately $2,942,000 over

  At December 31, 1998, no shares of either Ziff-Davis Inc. or ZDNet options
were exercisable.

  As permitted by SFAS No. 123, ZD has 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, 1997
or 1998. Pro forma information regarding net income is required by SFAS No. 123
and has been determined as if ZD 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, 1997 and 1998:

as follows:

</TABLE>

  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, 1997 and 1998, consistent
with the provisions of SFAS No. 123, ZD's net loss would have been increased by
approximately $3,000,000, $4,000,000 and $14,084,000, respectively.

 Other stock compensation plans

  During 1996, 1997 and 1998 employees of ZD were granted 45,760, 61,940 and
27,223 shares of common stock of SOFTBANK Corp., respectively (adjusted for a
1.4:1 stock split 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 3 to 5-year period from the date of grant. The granting of the shares to
ZD's employees has been recorded as additional paid-in capital offset by a
reduction to division 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 $1,080,000 was charged to expense related to
the restricted stock awards. During 1997, restrictions on 75,210 shares
expired, 2,150 shares were forfeited and $3,916,000 was charged to expense
related to these restricted stock awards. During 1998, restrictions on 22,361
shares expired, 5,736 shares were forfeited and $252,000 was charged to expense
related to these restricted stock awards.

 Employee Stock Purchase Plan

  In 1998, Ziff-Davis Inc. adopted the Employee Stock Purchase Plan (the "Stock
Purchase Plan") whereby eligible employees may purchase Ziff-Davis Inc.'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 (1) the first
business day of a purchase period or (2) the last business day of a purchase
period. Ziff-Davis Inc. has reserved 1,500,000 shares of common stock for
issuance under the Stock Purchase Plan.

  On December 21, 1998 the Board approved an amendment to the Employee Stock
Purchase Plan, subject to stockholder approval, to permit grants of options
with respect to any series of common stock of Ziff-Davis Inc. and increase the
number of shares available for sale to participants from 1,500,000 shares to
2,500,000 shares.

16. Employee Benefit Plans

 Pension plan

  Certain employees of ZD who have met eligibility requirements were covered by
a noncontributory defined benefit pension plan. The benefits are based on years
of service and average compensation at the time of retirement. ZD's 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.

  During 1997, ZD 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 amounts below reflect the effects of such termination. All
accrued plan obligations were settled during 1998 and a gain of $156,000 was
recognized in 1998 as a result of the plan settlement.

  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%.

 Interest rate swaps

  ZD utilizes interest rate swaps to reduce the impact on interest expense of
fluctuating interest rates on its variable rate debt. Under ZD's interest rate
swap agreements, ZD agreed with the counterparties to exchange, at quarterly
intervals, the difference between ZD's fixed pay rate and the counterparties'
variable pay rate on three-month LIBOR. At December 31, 1998, ZD was a fixed
payor of 5.85% on an aggregate notional amount of $550,000,000.

  The fair values of these interest rate swaps were estimated by obtaining
quotes from brokers which represented the amounts that ZD would pay if the
agreements were terminated at the balance sheet date. While it is not ZD's
intention to terminate these interest rate swaps, these fair values indicated
that the termination of the interest rate swap agreements would have resulted
in a loss of $15,627,000.

20. Operating Lease Commitments

  ZD utilizes equipment and space under lease to Ziff-Davis Inc. ZD's portion
of the minimum lease payments based on square feet utilized are as follows:

  Netted in the above totals is approximately $5,000,000 for which ZD has
noncancelable subleases in place. Total sublease income approximates ZD's
required payments under the related leases. Rent expense amounted to
approximately $22,347,000, $28,646,000 and $23,087,000 for the years ended
December 31, 1996, 1997and 1998, respectively.

21. Segment Information

  ZD has adopted the provisions of SFAS No. 131, Disclosure about Segments of
an Enterprise and Related Information. As such, prior years data has been
restated in accordance with SFAS No. 131.

 Business segment information

  Reportable segments are based on ZD's method of internal reporting which
segregates its business by product lines. Management measures operating
performance of the business segments based on "EBITDA". EBITDA is defined as
income before provision for income taxes, interest expense, depreciation and
amortization and restructuring charge. ZD's EBITDA is calculated by adding (a)
ZD's EBITDA before losses related to its retained interest in ZDNet and (b)
ZD's proportionate interest in ZDNet's EBITDA. 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 ZD's operating performance or to
cash flows as a measure of liquidity. Although ZD believes that EBITDA is a
standard measure commonly reported and widely used by analysts, investors and
other interested parties, in the publishing business and media industries, the
EBITDA presented for ZD may not be comparable to similarly titled measures
reported by other companies.

  ZD's reportable segments are:

 Publishing

  The publishing segment is engaged in publishing magazines, journals,
newsletters, online content, 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. The
publishing segment includes a 100% Retained Interest in ZDNet.

 Events

  The events segment is engaged in the organization, production and management
of trade shows, conferences and seminars for the computer industry. The events
segment's principal operations are in North America and to a lesser extent in
Europe, Asia and Latin America.

  The accounting policies of the segments are the same as those described in
Note 3 under "Summary of Significant Accounting Policies". ZD evaluates the
performance of its segments and allocates resources to them based on EBITDA.
Any inter-segment revenue included in segment data are not material. The
following presents information about the reported segments for the years ending
December 31:

22. Contingencies

  ZD is subject to various claims and legal proceedings arising in the normal
course of business.

 Class action and derivative litigations

  Following a decline in the price per share of Ziff-Davis Inc.'s common stock
in October 1998, eight securities class action suits were filed against Ziff-
Davis Inc. and certain of its directors and officers in the United States
District Court for the Southern District of New York.

  The complaints allege that defendants violated Sections 11, 12(a) (2) and 15
of the Securities Act of 1933 in connection with the registration statement
filed by Ziff-Davis Inc. with the Securities and Exchange Commission relating
to the initial public offering of Ziff-Davis Inc.'s common stock on April 29,
1998 (the "IPO"). More particularly, the complaints allege that the
registration statement contained false and misleading statements and failed to
disclose facts that could have indicated an impending decline in
Ziff-Davis Inc.'s revenue. The complaints seek on behalf of a class of
purchasers of Ziff-Davis Inc.'s common stock from the date of the IPO through
October 8, 1998 unspecified damages, interest, fees and costs, rescission, and
injunctive relief such as the imposition of a constructive trust upon the
proceeds of the IPO.

  On January 28, 1999, the court entered an order consolidating the actions,
appointing lead plaintiff's counsel and requiring the filing of a consolidated
amended complaint within 45 days. Thereafter, Ziff-Davis Inc. will have 45 days
to respond to the consolidated amended complaint.

  In addition, two derivative suits have been filed by stockholders against
Ziff-Davis Inc. and all of its directors in the Court of Chancery of the State
of Delaware for New Castle County. The complaints allege that the directors
breached their fiduciary duties to Ziff-Davis Inc. by repricing the stock
options awarded to certain directors and demand the nullification of the
repricing and an injunction against exercise by the directors of any repriced
option. The Plaintiffs filed an amended complaint on February 17, 1999 (which
is substantially similar to the original complaints, except that the amended
complaint also addresses the granting of "new options" at an allegedly "reduced
exercise price") and have indicated their intent to seek consolidation of the
actions. A response to the amended complaint has not yet been filed.

 Other legal proceedings

  Ziff-Davis Inc. was named as a defendant in an action, filed on April 17,
1998 in the Supreme Court of the State of New York, by minority stockholders of
SOFTBANK Interactive

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

Marketing Inc. ("SIM"), formerly an indirect subsidiary of SOFTBANK Corp. The
complaint alleges, among other things, that SBH, SIM's majority stockholder,
acting with Ziff-Davis Inc. and two of its senior officers and directors who
were directors of SIM (and who were also named as defendants), had conflicts of
interest between SIM and other Softbank investments (including investments in
Ziff-Davis Inc.) and failed to act in the best interests of SIM and the
minority stockholders by taking actions which benefited Ziff-Davis Inc. The
complaint states claims based on common law fraud, breach of fiduciary duty and
aiding and abetting theories and seeks in excess of $200,000,000 in damages.
Ziff-Davis Inc. and the other defendants have moved to dismiss all of the
claims against them other than a breach of contract claim which is solely
against SBH, and the motion was granted, with the result that all of the claims
against Ziff-Davis Inc. and its officers were dismissed, and most of the claims
against SBH were dismissed, leaving only a claim against SBH concerning the
alleged failure of SBH to give plaintiffs adequate notice of the sale of its
stock to SIM.

  Although the outcome of this case cannot be predicted, Ziff-Davis Inc.
believes that there are substantial defenses to the claims. Ziff-Davis Inc.
currently cannot estimate its ultimate liability, if any, with respect to such
pending litigations. Accordingly, no provision for such matters has been
included in the financial statements.

23. Subsequent Events

 DTV

  On February 4, 1999, ZD purchased ZDTV at a purchase price of approximately
$81,400,000. (See Note 14.) ZD paid approximately $32,800,000 of the purchase
price in cash (settled on February 5, 1999) and paid the remainder by applying
approximately $48,600,000 in advances owed to it by MAC Holdings America. ZD
also agreed to be responsible for the funding of ZDTV during the period in 1999
prior to the purchase which will be accounted for as additional purchase price.
Other than advances to ZDTV which are reported on ZD's balance sheet, the
results of operations of ZDTV are not included in ZD's results for any of the
periods presented. This acquisition will be accounted for in 1999 under the
purchase method of accounting.

 Vulcan transactions

  On February 5, 1999, Vulcan Programming, an entity owned by Paul G. Allen,
purchased a one-third interest in ZDTV for $54,000,000 in cash. On March 4,
1999, Vulcan Ventures, the investment vehicle of Paul G. Allen, purchased
approximately three million shares of Ziff-Davis Inc. common stock for
$50,000,000 in cash.

 Unaudited summary pro forma information

  The following unaudited summary pro forma information assumes that the
acquisition of ZDTV and the sale of a one-third interest in ZDTV to Vulcan
Programming had been consummated on January 1, 1998. Adjustments for ZDTV
transactions include the operating results of ZDTV, amortization of the
purchase price of ZDTV, Vulcan Programming's one-third interest in the losses
of ZDTV and the tax effect of these items. The pro forma data is not
necessarily indicative of actual results had the transaction occurred on
January 1, 1998. Further, pro forma results are not meant to represent future
financial results.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Ziff-Davis Inc.

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, cash flows and changes in stockholders'
equity, present fairly, in all material respects, the financial position of
Ziff-Davis Inc. and its subsidiaries (the "Company") at December 31, 1997 and
1998, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1998, 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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 (numbers rounded to the nearest thousand, except share and per share amounts)

1. The Company and Basis of Presentation

 Formation of Ziff-Davis Inc.

  Ziff-Davis Inc. was formed through an initial public offering and a
reorganization that were completed on May 4, 1998. (See Note 2.) Prior to that
date, the predecessors of Ziff-Davis Inc. (currently named ZD Inc. ("ZDI") and
ZD Events Inc.) were wholly owned indirect subsidiaries of SOFTBANK Corp
(together with its non-Ziff-Davis Inc. affiliates, "Softbank"). As such,
financial statements for periods prior to May 4, 1998 have been prepared on a
combined basis while the financial statements for the periods after May 4, 1998
have been prepared on a consolidated basis.

  As further described below, the consolidated financial statements include the
accounts of ZDI from its date of acquisition (February 29, 1996) and ZD Events
for all periods presented. In addition, the results of the MAC Assets (as
defined below) which were acquired in two tranches on October 31, 1997 and May
4, 1998 have been included in Ziff-Davis Inc.'s financial statements from the
time of their acquisition by MAC Inc. ("MAC") (February 29, 1996). These
results have been included in a manner similar to a pooling of interests, as
the MAC Assets, ZDI and ZD Events Inc. were under common control at the time
the MAC Assets were acquired by Ziff-Davis Inc. (See relationship with Softbank
and MAC below.)

 Relationship with Softbank and MAC

  SOFTBANK Corp. is the indirect majority stockholder of Ziff-Davis Inc.
SOFTBANK Corp. is a Japanese corporation which at the time of the acquisition
of the MAC Assets was majority owned directly and indirectly by its president,
Mr. Son. As of December 31, 1998, Mr. Son owned approximately 45% of SOFTBANK
Corp. (50.2% as of December 31, 1997). MAC, also a Japanese corporation, was
wholly owned by Mr. Son.

 Operations and acquisitions

  Ziff-Davis Inc. operates in three business segments: (1) publishing, (2)
events and (3) Internet.

 Publishing

  The publishing segment is engaged in publishing magazines, journals,
newsletters, electronic information products, training manuals and market
research about the computer industry. The publishing segment's principal
operations are in the U.S. and Europe, although it also licenses or syndicates
its editorial content to over 50 other publications distributed worldwide.

 Events

  The events segment is engaged in the organization, production and management
of trade shows, conferences and seminars for the computer industry. The events
segment's principal operations are in the U.S. and to a lesser extent in Europe
and Asia.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


 Internet

  The Internet segment is engaged in providing technology related information
to Internet users worldwide. The Internet segment's principal operations are in
the U.S. and to a lesser extent in Europe.

 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 $1,800,000,000,
plus transaction costs. Concurrent with the acquisition, in a separate
agreement, MAC, 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 $302,000,000.

  These acquisitions 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 $1,922,000,000 and
$285,000,000, respectively.

  Subsequent to the acquisition, Holdings and ZDI were merged with ZDI being
the surviving corporation.

 Purchase of the MAC Assets

  In 1997, ZDI agreed to purchase certain of the MAC Assets for $370,000,000.
The acquisition was effected in two tranches, the first of which closed on
October 31, 1997 and the second of which closed upon completion of the initial
public offering of Ziff-Davis Inc.'s common stock (further described below). At
December 31, 1997, ZDI had accrued the $370,000,000 purchase price which was
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 were under common
control at the time of the acquisitions. Accordingly, the accompanying
consolidated financial statements include the results of operations of 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
$27,500,000, plus transaction costs. The acquisition was accounted for as a
purchase and accordingly, Sendai's results are included in the consolidated
financial statements since the date of acquisition. The excess of the purchase
price over assets acquired approximated

 (numbers rounded to the nearest thousand, except share and per share amounts)

$33,378,000. The operations of Sendai did not have a material effect on the
consolidated results of operations for the year ended December 31, 1996.

 Acquisition of Sky TV

  On October 28, 1998, Ziff-Davis Inc. acquired the assets of Sky TV Inc. and
certain affiliates for approximately $12,150,000 in cash plus contingent
payments related to earnings performance payable in 2002. Sky TV is a media
company that produces video content for distribution principally through
airline in-flight, cable and broadcast television. The acquisition was
accounted for as a purchase and accordingly Sky TV's results are included in
the consolidated financial statements since the date of acquisition. The excess
of the purchase price over assets acquired approximated $11,318,000. The
operations of Sky TV did not have a material effect on consolidated results of
operations for the year ended December 31, 1998.

2. Reorganization, Initial Public Offering and ZDNet Stock Proposal

  On February 4, 1998, a nonstock corporation, ZD Inc., was formed in
contemplation of a reorganization and initial public offering of Ziff-Davis
Inc. Upon completion of the initial public offering (described below),
Ziff-Davis Inc. was renamed ZD Inc. and ZDCF was renamed ZD Events Inc. and ZD
Inc. was renamed Ziff-Davis Inc.

  On May 4, 1998 SOFTBANK Corp., through its wholly owned subsidiary SOFTBANK
Holdings Inc. ("SBH"), completed a reorganization whereby the common stock of
ZD Inc. and ZD Events Inc. were contributed to Ziff-Davis Inc. in exchange for
73,619,335 shares of Ziff-Davis Inc.'s common stock. Concurrent with the
reorganization, Ziff-Davis Inc. (1) completed an initial public offering of
25,800,000 common shares at an initial public offering price of $15.50 per
share, (2) issued $250,000,000 of 8 1/2% subordinated notes due 2008,
(3) entered into a $1,350,000,000 credit facility with a group of banks under
which $1,250,000,000 was borrowed and (4) converted $908,673,000 of
intercompany indebtedness to equity. In addition, Ziff-Davis Inc. received
approximately $9,107,000 of fixed assets from Kingston Technology Company
("Kingston"), a related party, in exchange for 580,645 shares of Ziff-Davis
Inc.'s common stock and $107,000 in cash. These assets have been subsequently
leased back to Kingston. Total shares of common stock issued to Softbank were
74,200,000. The transactions described above are hereafter referred to as the
"Reorganization".

  Proceeds, net of transaction costs, from the initial public offering and
funding transactions in the Reorganization of $1,863,260,000 were used to
complete the purchase of certain assets from MAC for $370,000,000 and repay
intercompany indebtedness.

  On May 28, 1998, Ziff-Davis Inc.'s U.S. underwriters exercised their option
to purchase 2.0 million additional shares of common stock to cover over-
allotments. Ziff-Davis Inc.

purchased the additional shares from SBH resulting in no change to the total
number of shares outstanding. On December 31, 1998, SBH contributed 71,619,355
shares of Ziff-Davis Inc.'s common stock to SOFTBANK America Inc., an affiliate
of SOFTBANK Corp.

 Unaudited pro forma financial information

  The following summary pro forma information has been prepared as if the
Reorganization and initial public offering described above, had been
consummated on January 1, 1998. The pro forma adjustments include a $5,219,000
reduction of interest expense, a $900,000 increase in depreciation expense and
a $900,000 reduction of selling, general and administrative expenses, as well
as the tax effect of these items recorded at an effective tax rate of 40%.

 ZDNet Stock Proposal (unaudited)

  The stockholders of Ziff-Davis Inc. are scheduled to vote on a proposal (the
"Tracking Stock Proposal") to authorize the issuance of a new series of common
stock, to be designated as Ziff-Davis Inc.--ZDNet Common Stock ("ZDNet Stock"),
intended to reflect the performance of Ziff-Davis Inc.'s online business
division ("ZDNet"). The majority owner of the common stock of Ziff-Davis Inc.
has committed to vote for the Tracking Stock Proposal. Before the ZDNet Stock
is first issued, Ziff-Davis Inc.'s existing common stock will be re-classified
as Ziff-Davis Inc.--ZD Common Stock ("ZD Stock") and that stock will be
intended to reflect the performance of Ziff-Davis Inc.'s other businesses and a
"Retained Interest" in ZDNet (i.e., Ziff-Davis Inc.'s interest in ZDNet
excluding the interest intended to be represented by outstanding shares of
ZDNet Stock) (collectively, "ZD").

  ZD currently has a 100% Retained Interest in ZDNet. Following approval of the
Tracking Stock Proposal, Ziff-Davis Inc. currently plans to offer to the
public, for cash, 10,000,000 shares of ZDNet Stock intended to represent
approximately 14% of the equity value attributed to ZDNet. Ziff-Davis Inc.
expects to offer ZDNet Stock to the public sometime in the first or second
quarter of 1999. However, Ziff-Davis Inc. could choose to

conduct the offering at a later time, or not to make the offering at all,
depending on the circumstances at the time. In addition to or instead of the
offering, Ziff-Davis Inc. reserves the right to distribute ZDNet Stock to
stockholders of Ziff-Davis Inc.

3. Summary of Significant Accounting Policies

 Principles of combination and consolidation

  Prior to the Reorganization, the financial statements were prepared on a
combined basis to include the accounts of ZDI and ZD Events including, as
discussed above, the MAC Assets. The financial statements of Ziff-Davis Inc.
prepared subsequent to the Reorganization described above have been prepared on
a consolidated basis. All significant transactions between these entities have
been eliminated in combination and consolidation.

  Investments in companies in which Ziff-Davis Inc.'s ownership interests range
from 20% to 50% and in which Ziff-Davis Inc. has the ability to exercise
significant influence over the operating and financial policies of such
companies are accounted for under the equity method.

 Cash and cash equivalents

  Ziff-Davis Inc. considers all highly liquid investments with an original
maturity of 3 months or less to be cash equivalents.

 Concentration of credit risk

  Ziff-Davis Inc. places its temporary cash investments with high credit
quality financial institutions. At times, such investments may be in excess of
federally insured limits. Ziff-Davis Inc. has not experienced losses in such
accounts.

  Ziff-Davis Inc.'s advertisers and exhibitors include principally customers
who represent a variety of technology companies in the U.S. and other
countries. Ziff-Davis Inc. extends credit to its customers and distributors 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 cost or estimated fair value at
the date of acquisition. Depreciation is computed using the straight-line
method, half-year convention, over the estimated useful lives of the assets
which range from 3 to 30 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.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

 Debt issuance costs and discount on senior subordinated notes

  The cost to issue debt is recorded in the balance sheet in other assets and
amortized to interest expense over the life of the debt. The discount on the
senior subordinated notes is recorded in the balance sheet as a reduction of
long-term debt and is amortized to interest expense over the life of the notes.
All amounts are amortized utilizing the effective-interest method.

 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 estimated useful lives.
Identifiable 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. (See Note 7.) Ziff-Davis Inc. assesses the recoverability of 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 value of
assets, an impairment loss is recognized to reduce the carrying value of the
intangibles to estimated recoverable value.

 Revenue recognition

  Advertising revenue for Ziff-Davis Inc.'s 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.

  Online revenue is derived principally from the sale of advertisements on
short-term contracts. Online revenue is recognized ratably in the period in
which the advertisement is

displayed, provided that no significant obligations remain and collection of
the resulting receivable is probable. Ziff-Davis Inc.'s obligations typically
include guarantees of minimum number of "impressions", or times that an
advertisement appears in pages viewed by users of Ziff-Davis Inc.'s online
properties. To the extent minimum guaranteed impressions are not met, Ziff-
Davis Inc. defers recognition of the corresponding revenues until the remaining
guaranteed impression levels are achieved.

 Operating costs and expenses

  Cost of production includes the direct costs of producing magazines, online
content, 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.

 Reportable segments

  In 1998, Ziff-Davis Inc. adopted Statement of Financial Accounting Standards
("SFAS") No. 131, Disclosures about Segments of an Enterprise and Related
Information. SFAS No. 131 supersedes SFAS No. 14, Financial Reporting for
Segments of a Business Enterprise, replacing the "industry segment" approach
with the "management" approach. The management approach designates the internal
organization that is used by management for making operating decisions and
assessing performance as the source of Ziff-Davis Inc.'s reportable segments.
SFAS No. 131 also requires disclosures about products and services, geographic
areas and major customers. The adoption of SFAS No. 131 did not affect results
of operations or financial position but did affect the disclosure of segment
information. (See Note 19.)

 Foreign currency

  The effect of translating foreign currency financial statements into U.S.
dollars is included in the cumulative translation adjustments account in
stockholders' equity. Gains and losses on foreign currency transactions, which
are not significant to operations, have been included in selling, general and
administrative expenses. Ziff-Davis Inc. has not historically entered into
forward currency contracts.

 Other non-operating income

  Other non-operating income includes management fee income and Ziff-Davis
Inc.'s equity share of income or loss from joint ventures.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
      (numbers rounded to the nearest thousand, except per share amounts)

 Income taxes

  Ziff-Davis Inc. 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

  Ziff-Davis Inc.'s financial instruments recorded on the balance sheet include
cash and cash equivalents, accounts receivable, accounts payable and debt.
Because of their short maturity, the carrying amount of cash and cash
equivalents, accounts receivable and accounts payable approximate fair value.
Fair value of long-term bank debt is based on rates available to Ziff-Davis
Inc. for debt with similar terms and maturities. Fair value of public debt is
based on market prices.

  Ziff-Davis Inc. uses interest rate swap agreements to manage risk on its
floating rate debt portfolio. Fair value of these instruments is based on
estimated current settlement cost.

 Interest rate swaps

  Ziff-Davis Inc. periodically uses interest rate swaps to manage its exposure
to interest rate fluctuations on its floating rate debt. These interest rate
swaps are entered into for hedging purposes and as such, must be designated and
effective as a hedge against the risk of increased interest rates. Under the
terms of the agreements Ziff-Davis Inc. pays a fixed interest rate on a
notional amount and receives a variable interest rate on the same notional
amount. The differential between the amounts paid and received is recorded as
additional interest expense. Interest rate swaps designated but no longer
effective as a hedge would be reported at market value and the related gains
and losses would be recognized in earnings. Gains or losses on termination of
interest rate swaps would be recognized in earnings in the period of
termination.

 Stock-based compensation

  Ziff-Davis Inc. has elected to follow Accounting Principles Board Opinion No.
25, Accounting for Stock Issued to Employees ("APB 25"), to account for stock
options. Effective January 1, 1996, Ziff-Davis Inc. adopted the disclosure-only
provisions of Statement of Financial Accounting Standard ("SFAS") No. 123,
Accounting for Stock-Based Compensation.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


 Earnings per share

  Earnings per share data for 1996 and 1997 have been omitted on the basis that
they are not meaningful due to the insignificant number of shares outstanding.
Earnings per share data for 1998 is calculated on a pro forma basis as if the
shares issued in connection with the Reorganization and initial public offering
described in Note 2 were outstanding as of January 1, 1998. Options to purchase
Ziff-Davis Inc. common stock that could potentially dilute basic earnings per
share in the future were not included in the computation of diluted loss per
share because they were anti-dilutive. There were options to purchase 6,691,305
shares of Ziff-Davis Inc. common stock outstanding at December 31, 1998.

 Comprehensive income

  Ziff-Davis Inc. implemented SFAS No. 130. Reporting Comprehensive Income,
effective January 1, 1998. This standard requires Ziff-Davis Inc. to report the
total changes in stockholders' equity that do not result directly from
transactions with stockholders, including those which do not affect retained
earnings. These changes are not material to Ziff-Davis Inc.'s consolidated
financial statements.

 New accounting pronouncement

  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133
Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133
establishes accounting and reporting standards for derivative instruments and
for hedging activities and is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. Ziff-Davis Inc. does not expect the adoption of
SFAS No. 133 to have a material impact on Ziff-Davis Inc.'s results of
operations. Ziff-Davis Inc. will adopt SFAS No. 133 beginning with its 2000
financial statements.

 Reclassifications

  Certain amounts have been reclassified, where appropriate, to conform to the
current financial statement presentation.

4. Restructuring

  Margin pressure on computer equipment manufacturers, industry and product
delays, lower demand in Asia and a focus on the Year 2000 transition are
contributing to a reduced demand for advertising in Ziff-Davis Inc.'s
magazines, principally PC Magazine, PC/Computing, Computer Shopper and PC Week.
Ziff-Davis Inc. believes these factors are continuing.

  As a result of this reduced demand, in October 1998 Ziff-Davis Inc. announced
a restructuring program with the intent of significantly reducing its cost
base. Ziff-Davis Inc.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)

incurred a pre-tax charge of $52,239,000 for this restructuring program. The
charge included asset impairment costs ($37,890,000), employee termination
costs ($8,668,000) and costs to exit activities ($5,681,000) principally
resulting from the closing of three publications (Windows Pro, Internet
Business and Equip) and the reduction of Ziff-Davis Inc.'s work force by 310
employees. The charge also included costs resulting from the discontinuation of
certain educational journals and trade shows. The following sets forth
additional detail concerning the principal components of the charge:

  .  Asset impairment costs totaled $37,890,000. These costs, which are non-
     cash, included the write-off of intangible assets, primarily subscriber
     lists, advertising lists, tradenames and goodwill, associated with the
     discontinued publications ($34,245,000) and trade shows ($2,930,000) as
     well as deferred marketing expenses associated with the discontinued
     educational journals ($715,000).

  .  Employee termination costs related to severed personnel at the closed
     publications as well as a rationalization and resulting workforce
     reduction of the remainder of Ziff-Davis Inc.'s operations. Employee
     termination costs included payments for severance and earned vacation as
     well as the costs of outplacement services and the provision of
     continued benefits to personnel. As of December 31, 1998, $5,200,000 of
     the $8,668,000 related to these employee terminations had been paid.

  .  Costs to exit activities reflect the costs associated with the final
     closure of the discontinued publications ($1,837,000) and the costs to
     reduce office space under lease as a result of the reduced level of
     employees ($3,844,000).

  Included in accrued expenses is $7,260,000 related to this restructuring
which Ziff-Davis Inc. believes will be paid during the first half of 1999.

  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, the purchase price of these
acquisitions 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 estimated fair value as determined by an income approach. Trademarks/trade
names were recorded at estimated fair value using a relief from royalty
approach.

  All intangible assets are being amortized using the straight-line method over
estimated useful lives, up to 40 years. In determining the estimated useful
lives, Ziff-Davis Inc.

considered its competitive position in the markets in which it operates, 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. In connection with the restructuring described in Note 4, Ziff-
Davis Inc. recorded a $37,175,000 write-down of intangible assets associated
with discontinued publications and events.

  Prior to the Reorganization and initial public offering described in Note 2,
the subsidiaries of Ziff-Davis Inc. had 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 consolidated statements of operations and tax
liabilities reflected in the consolidated balance sheet have been prepared on a
separate return basis as though Ziff-Davis Inc. filed stand-alone income tax
returns. No tax benefit has been recorded for the losses related to

  The effective tax rate differs from the federal statutory tax rate primarily
as a result of Ziff-Davis Inc.'s inability to deduct losses of the MAC Assets
prior to May 4, 1998. The amortization of non-deductible goodwill resulted
primarily from the acquisition of 100% of the stock of Holdings in 1996.

to the expiration of foreign net operating loss carryforwards. No deferred tax
asset has been established for the losses associated with the MAC Assets,
inasmuch as such losses will not be available to Ziff-Davis Inc.

  At December 31, 1998, Ziff-Davis Inc. had U.S. and foreign net operating loss
carryforwards of approximately $195,943,000 which began to expire in 1998.
Ziff-Davis Inc.'s utilization of certain net operating loss carryforwards, of
approximately $122,549,000, is subject to limitations, due to the change of
ownership resulting from the Softbank acquisition of the Holdings stock on
February 29, 1996. Management believes that such limitations will not
significantly affect Ziff-Davis Inc.'s 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, Ziff-Davis Inc. has alternative minimum tax credit
carryforwards of $385,000 which may be carried forward indefinitely until used.

  Undistributed earnings of foreign subsidiaries for which no deferred taxes
have been provided approximate $2,789,000 at December 31, 1998. Any additional
U.S. taxes payable on these foreign earnings, if remitted, would be
substantially offset by credits for foreign taxes already paid.

 8 1/2% senior subordinated notes

  On May 4, 1998 Ziff-Davis Inc. issued 8 1/2% Senior Subordinated Notes due
2008 (the "Notes") in the aggregate principal amount of $250,000,000. The Notes
were issued at a discount of $915,000 which is being amortized to interest
expense over the term of the Notes. Included in the balance sheet at December
31, 1998 as a reduction of long-term debt is $870,000 representing the
unamortized discount on the Notes. Interest on the Notes is payable semi-
annually on May 1 and November 1 of each year. Redemption of the Notes by Ziff-
Davis Inc. is subject to certain limitations. The Notes are subordinated to all
existing and future senior indebtedness.

 Credit facility

  Ziff-Davis Inc. is party to a secured guaranteed credit agreement with The
Bank of New York, Morgan Stanley Senior Funding, DLJ Capital Funding and The
Chase Manhattan Bank, as agents, to provide a $1,350,000,000 term credit
facility. The amount outstanding under this facility at December 31, 1998 was
$1,220,000,000. The credit facility consists of (1) a seven-year $400,000,000
reducing revolving credit facility, with $270,000,000 drawn

 (numbers rounded to the nearest thousand, except share and per share amounts)

as of December 31, 1998, (2) a seven-year $450,000,000 term loan ("Term Loan
A") and (3) an eight-year $500,000,000 term loan ("Term Loan B"). Under the
credit facility, Ziff-Davis Inc. paid interest at rates ranging from LIBOR plus
1.5% to LIBOR plus 1.75%. See "--Amendment to credit facility" below.

There are various customary conditions to draw-downs under the revolving
commitments. The revolving credit commitments will be reduced and the $450
million Term Loan A will be amortized, beginning in September 2000, by:

  . 10% in 2000, in two equal quarterly installments,

  . 20% in each of 2001, 2002, 2003 and 2004 in four equal quarterly
    installments and

  . 10% at final maturity in March 2005.

The $500 million Term Loan B will be amortized, beginning in September 2000,
by:

  . $2 million in 2000, in two equal quarterly installments,

  . $4 million in each of 2001, 2002, 2003, 2004 and 2005 in four equal
    quarterly installments and

  . $478 million at final maturity in March 2006.

  The Notes and the credit facility are secured, in part, by a first priority
security interest in capital stock of certain subsidiaries of Ziff-Davis Inc.
and are guaranteed by certain wholly owned domestic subsidiaries of Ziff-Davis
Inc., in each case, including ZD Inc. and ZD Events.

  Under its most restrictive covenant, Ziff-Davis Inc. could have borrowed an
additional $28,800,000 under the credit facility at December 31, 1998.

 Covenants

  The Notes and the credit facility contain certain customary affirmative and
negative covenants, including covenants with respect to limitations on
dispositions of assets, changes of business and ownership, mergers or
acquisitions, restricted payments, indebtedness, loans and investments and
transactions with affiliates. The Notes and the credit facility also contain
certain financial covenants including levels of debt to EBITDA and EBITDA to
interest ratios.

  The failure to satisfy any of the covenants would constitute an event of
default under the credit facility. The credit facility also includes 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. At December 31, 1998,
management believes that Ziff-Davis Inc. was in compliance with all covenants
under its debt agreements.

 Amendment to credit facility

  On December 16, 1998, the lenders on Ziff-Davis Inc.'s $1,350,000,000 credit
facility agreed to amend certain provisions of that facility. The amended
provisions include an increase in allowed leverage ratios. In return, Ziff-
Davis Inc. agreed to pay a one-time fee of $3,375,000 and increase rates on
amounts borrowed under the facility to rates currently ranging from LIBOR plus
2.875% to LIBOR plus 3.375%, depending on the type of loan. The fee has been
capitalized and will be amortized to interest expense over the remaining term
of the facility.

 Related-party debt

  In March 1995, Ziff-Davis Inc. entered into a $100,000,000 note payable to
Softbank due in quarterly installments, maturing on February 28, 2010 and
bearing interest at 9.9% per annum. (See Note 12.)

 Interest rate swaps

  On June 10, 1998 Ziff-Davis Inc entered into interest rate swap agreements,
with an aggregate notional amount of $550,000,000. Under these swap agreements,
which took effect on August 10, 1998, Ziff-Davis Inc. receives a floating rate
of interest based on three-month LIBOR, which resets quarterly, and Ziff-Davis
Inc. pays a fixed rate of interest, each quarter, for the terms of the
respective agreements. The terms of these agreements range from 3 to 7 years
and the weighted average fixed rate Ziff-Davis Inc. pays is 5.85%. Ziff-Davis
Inc. has entered into these agreements solely to hedge its interest rate risk
under its floating rate bank debt.

  For the year ended December 31, 1998, these interest rate swaps did not have
a material impact on the financial statements.

  As part of the 1996 acquisition of ZDI, Ziff-Davis Inc. agreed to assume
certain obligations to management arising out of prior employment arrangements
with previous owners. In January 1997, Ziff-Davis Inc. paid all amounts due,
including accrued interest, through the payment date.

  Prior to the Reorganization and initial public offering, Ziff-Davis Inc. was
a member of Softbank's central cash management system. Under this system, Ziff-
Davis Inc. would periodically transfer excess cash to Softbank for cash
management purposes and in turn receive cash advances from Softbank to fund
Ziff-Davis Inc.'s short-term working capital requirements. Interest was accrued
based on the net balance outstanding at the end of each month. Interest income
was earned at the 30-day LIBOR rate for the applicable month. Interest expense
was incurred at the 30-day LIBOR rate plus 0.5%.

  As a result of contingent purchase price adjustments related to its
acquisition of Inter@ctive Enterprises, Ziff-Davis Inc. is obligated to pay the

related to the above notes payable.

 Guarantee of Softbank's U.S. debt

  In April 1996, Softbank signed a line of credit agreement totaling
$50,000,000 with an independent lender for which Ziff-Davis Inc., along with
certain other SOFTBANK Corp. affiliates, is a guarantor. In January 1997,
October 1997 and March 1998, this line of credit was increased to $75,000,000,
$150,000,000 and $450,000,000, respectively. On May 4, 1998, Ziff-Davis Inc.
was released from this guarantee.

 Return of capital and dividends

  On December 15, 1996, Ziff-Davis Inc. declared a return of capital of
approximately $900,000,000 paid through the issuance of a note payable to a
subsidiary of Softbank and a cash dividend of $8,000,000 to Softbank. In 1997,
Ziff-Davis Inc. recorded a return of capital of $381,434,000 in connection with
the purchase price of companies under common control.

13. Stock Compensation Plans

 Softbank Executive Stock Option Plans

  The SOFTBANK Executive Stock Option Plans provide for the granting of
nonqualified stock options (the "Softbank Options") to purchase the common
stock of SOFTBANK Corp. to officers, directors and key employees of Ziff-Davis
Inc. SOFTBANK Corp. is a publicly traded company in Japan. 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, 1998, 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. On January 19,
1998, the exercise price of all of the shares outstanding under option
agreements was reset to (Yen)4,000, 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 could only be exercised after July 19, 1998.
The repricing did not result in compensation expense to Ziff-Davis Inc.

 1998 Incentive Compensation Plan and the 1998 Non-Employee Directors' Stock
Option Plan

  In 1998, Ziff-Davis Inc. adopted the 1998 Incentive Compensation Plan (the
"Incentive Plan") and the 1998 Non-Employee Directors' Stock Option Plan (the
"Non-Employee Directors' Plan"). The Incentive Plan provides for the grant of
options, stock appreciation rights, stock awards and other interests in Ziff-
Davis Inc.'s common stock to key employees of Ziff-Davis Inc. and its
affiliates and consultants. The Non-Employee Directors' Plan provides for the
grant of stock options to non-employee directors. Ziff-Davis Inc. has reserved
8,500,000 shares of common stock for issuance under the Incentive Plan and
200,000 shares of common stock for issuance under the Non-Employee Directors'
Plan. During 1998, Ziff-Davis Inc. granted options to purchase 6,757,495 shares
with exercise prices ranging from $6.00 to $16.00 per share representing the
fair value of such options at that date. Such options vest ratably over five
years.

  On September 23, 1998, the Board approved the reduction of the exercise price
of all options outstanding under the Incentive Plan from $16.00 to $6.00, the
closing market price of Ziff-Davis Inc.'s common stock on that date. In
addition, the vesting period of the options was extended by three months. The
repricing did not result in compensation expense to Ziff-Davis Inc.

  On December 21, 1998 the Board approved an amendment to the Incentive Plan to
permit grants of options and other stock-based awards with respect to any
series of common stock of Ziff-Davis Inc. and to increase the number of shares
available for issuance from 8,500,000 shares to 17,827,500 shares.

  In addition, on December 21, 1998, the Board approved the grant of options to
acquire an aggregate of approximately 5,729,000 shares of ZDNet Stock to
certain employees at a price of $7.50 per share. As a result of the grant Ziff-
Davis Inc. has recorded deferred compensation expense of $18,262,000 for the
difference between the exercise price and the deemed fair value of the
underlying shares. This amount has been recorded as a component of
stockholders' equity offset by an addition to paid-in capital. Ziff-Davis Inc.
expects to recognize non-cash compensation for accounting purposes of
$18,262,000 ratably over the vesting period of the options. These options are
currently scheduled to vest and become exercisable on the fifth anniversary of
the date of grant.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


  The terms of the options described in the preceding paragraph require an
adjustment in the number of shares of ZDNet Stock that holders may purchase and
the per share purchase price thereof if the initial number of shares issuable
with respect to ZD's Retained Interest in ZDNet is different from 40,000,000.
This adjustment is similar to the adjustment that would generally be made to
the terms of employee stock options in the event of a stock split. Ziff-Davis
Inc. currently expects that the initial Number of Shares Issuable with Respect
to ZD's Retained Interest in ZDNet will be 70,000,000. Assuming that this is
so, the total number of shares of ZDNet Stock that holders may purchase upon
exercise of these options will increase to approximately 10,026,000 and the per
share purchase price thereof will decrease to approximately $4.29.

  The December 21, 1998 Board actions described above are subject to
stockholder approval. The majority owner of the common stock of Ziff-Davis Inc.
has committed to approve these actions.

  On January 29, 1999, Ziff-Davis Inc. granted options to a number of employees
in connection with the cancellation of corresponding options to purchase stock
of SOFTBANK Corp. In connection with these grants, an affiliate of SOFTBANK
Corp. has agreed with Ziff-Davis Inc. that, if and when any of these options
are exercised, (1) that affiliate will cause the shares of Ziff-Davis Inc.
common stock issuable upon such exercise to be supplied to Ziff-Davis Inc. and
(2) Ziff-Davis Inc. will deliver to that affiliate or its designee the exercise
price paid upon such exercise. Thus, the exercise of these options will not
increase the number of shares of Ziff-Davis Inc. common stock outstanding or
Ziff-Davis Inc.'s stockholders' equity. However, Ziff-Davis Inc. expects to
recognize compensation expense for accounting purposes of approximately
$3,018,000 over three years as a result of these grants. As such, this amount
has been recorded in the Financial Statements as additional paid in capital
offset by a reduction to stockholders' equity as deferred compensation.

 GameSpot Inc. 1997 Stock Option Plan

  Ziff-Davis Inc. adopted the GameSpot Inc. 1997 Stock Option Plan (the
"GameSpot Plan") to provide long-term incentives for key employees of GameSpot
and to enhance stockholder value. The GameSpot Plan provides for the grant of
options to purchase shares of GameSpot Inc.'s common stock. GameSpot has
reserved 800,000 shares of GameSpot Inc.'s common stock for issuance under the
GameSpot Plan. Such options vest ratably over 3 years.

  As permitted by SFAS No. 123, Ziff-Davis Inc. has 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, 1997 or 1998. Pro forma information regarding net income is
required by SFAS No. 123 and has been determined as if Ziff-Davis Inc. 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, 1997 and 1998:

      (numbers rounded to the nearest thousand, except per share amounts)

1996, 1997 and 1998 consistent with the provisions of SFAS No. 123, Ziff-Davis
Inc.'s net loss would have been increased by approximately $3,100,000,
$4,200,000 and $15,130,000, respectively.

 Other stock compensation plans

  During 1996, 1997 and 1998, Ziff-Davis Inc. granted 45,760, 61,940 and 27,223
shares of common stock of SOFTBANK Corp. respectively (adjusted for a 1.4:1
stock split 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 3 to 5-year period from the date of grant. The granting of the shares to
Ziff-Davis Inc.'s employees has been recorded as additional paid-in capital
offset by a reduction to stockholders' 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 $1,080,000 was charged to expense
related to the restricted stock awards. During 1997, restrictions on 75,210
shares expired, 2,150 shares were forfeited and $3,916,000 was charged to
expense related to these restricted stock awards. During 1998, restrictions on
22,361 shares expired, 5,736 shares were forfeited and $252,000 was charged to
expense related to these restricted stock awards.

 Employee Stock Purchase Plan

  In 1998, Ziff-Davis Inc. adopted the Employee Stock Purchase Plan (the "Stock
Purchase Plan") whereby eligible employees may purchase Ziff-Davis Inc.'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 (1) the first
business day of a purchase period or (2) the last business day of a purchase
period. Ziff-Davis Inc. has reserved 1,500,000 shares of common stock for
issuance under the Stock Purchase Plan.

  On December 21, 1998 the Board approved an amendment to the Employee Stock
Purchase Plan, subject to stockholder approval, to permit grants of options
with respect to any series of common stock of Ziff-Davis Inc. and increase the
number of shares available for sale to participants from 1,500,000 shares to
2,500,000 shares.

14. Employee Benefit Plans

 Pension plan

  Certain employees of Ziff-Davis Inc. who have met eligibility requirements
were covered by a noncontributory defined benefit pension plan. The benefits
are based on years of service and average compensation at the time of
retirement. Ziff-Davis Inc.'s funding policy

 (numbers rounded to the nearest thousand, except share and per share amounts)

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.

  During 1997, Ziff-Davis Inc. 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 amounts below reflect the effects of such termination.
All accrued obligations were settled during 1998 and a gain of $156,000 was
recognized in 1998 as a result of the plan settlement.

  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:

18. Contingencies

  Ziff-Davis Inc. is subject to various claims and legal proceedings arising in
the normal course of business.

 Class action and derivative litigations

  Following a decline in the price per share of Ziff-Davis Inc.'s common stock
in October 1998, eight securities class action suits were filed against Ziff-
Davis Inc. and certain of its directors and officers in the United States
District Court for the Southern District of New York.

  The complaints allege that defendants violated Sections 11, 12(a) (2) and 15
of the Securities Act of 1933 in connection with the registration statement
filed by Ziff-Davis Inc. with the Securities and Exchange Commission relating
to the initial public offering of Ziff-Davis Inc.'s stock on April 29, 1998
(the "IPO"). More particularly, the complaints allege that the registration
statement contained false and misleading statements and failed to disclose
facts that could have indicated an impending decline in Ziff-Davis Inc.'s
revenue. The complaints seek on behalf of a class of purchasers of Ziff-Davis
Inc.'s common stock from the date of the IPO through October 8, 1998
unspecified damages, interest, fees and costs, rescission, and injunctive

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 (numbers rounded to the nearest thousand, except share and per share amounts)


  On January 28, 1999, the court entered an order consolidating the actions,
appointing lead plaintiff's counsel and requiring the filing of a consolidated
amended complaint within 45 days. Thereafter, Ziff-Davis Inc. will have 45 days
to respond to the consolidated amended complaint.

  In addition, two derivative suits have been filed by stockholders against
Ziff-Davis Inc. and all of its directors in the Court of Chancery of the State
of Delaware for New Castle County. The complaints allege that the directors
breached their fiduciary duties to Ziff-Davis Inc. by repricing the stock
options awarded to certain directors and demand the nullification of the
repricing and an injunction against exercise by the directors of any repriced
option. Plaintiffs filed an amended complaint on February 17, 1999 (which is
substantially similar to the original complaints, except that the amended
complaint also addresses the granting of "new options" at an allegedly "reduced
exercise price") and have indicated their intent to seek consolidation of the
actions. A response to the amended complaint has not yet been filed.

 Other legal proceedings

  Ziff-Davis Inc. was named as a defendant in an action, filed on April 17,
1998 in the Supreme Court of the State of New York, by minority stockholders of
SOFTBANK Interactive Marketing Inc. ("SIM"), formerly an indirect subsidiary of
SOFTBANK Corp. The complaint alleges, among other things, that SBH, SIM's
majority stockholder, acting with Ziff-Davis Inc. and two of its senior
officers and directors who were directors of SIM (and who were also named as
defendants), had conflicts of interest between SIM and other Softbank
investments (including investments in Ziff-Davis Inc.) and failed to act in the
best interests of SIM and the minority stockholders by taking actions which
benefited Ziff-Davis Inc. The complaint states claims based on common law
fraud, breach of fiduciary duty and aiding and abetting theories and seeks in
excess of $200,000,000 in damages. Ziff-Davis Inc. and the other defendants
have moved to dismiss all of the claims against them other than a breach of
contract claim which is solely against SBH, and the motion was granted, with
the result that all of the claims against Ziff-Davis Inc. and its officers were
dismissed, and most of the claims against SBH were dismissed, leaving only a
claim against SBH concerning the alleged failure of SBH to give plaintiffs
adequate notice of the sale of its stock to SIM.

  Although the outcome of these cases cannot be predicted, Ziff-Davis Inc.
believes that there are substantial defenses to the claims. Ziff-Davis Inc.
currently cannot estimate its ultimate liability, if any, with respect to such
pending litigations. Accordingly, no provision for such matters has been
included in the financial statements.

19. Segment Information

  Ziff-Davis Inc. has adopted the provisions of SFAS No. 131 Disclosures about
Segments of an Enterprise and Related Information. As such, prior years data
has been restated in accordance with SFAS No. 131.

 Business segment information

  Ziff-Davis Inc.'s reportable segments are based on its method of internal
reporting, which segregates its business by product lines. Management measures
operating performance of the business segments based on "EBITDA". EBITDA is
defined as income before provision for income taxes, interest expense,
depreciation and amortization and restructuring charges. 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 Ziff-Davis Inc.'s operating
performance or to cash flows as a measure of liquidity. Although Ziff-Davis
Inc. believes that EBITDA is a standard measure commonly reported and widely
used by analysts, investors and other interested parties in the publishing
business and media industries, the EBITDA presented for Ziff-Davis Inc. may not
be comparable to similarly titled measures reported by other companies.

  Ziff-Davis Inc.'s reportable segments are:

 Publishing

  The publishing segment is engaged in publishing magazines, journals,
newsletters, online content, 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.

 Events

  The events segment is engaged in the organization, production and management
of trade shows, conferences and seminars for the computer industry. The events
segment's principal operations are in North America and to a lesser extent in
Europe, Asia and Latin America.

 Internet

  The Internet segment is engaged in providing technology-related information
to Internet users worldwide. The Internet segment's principal operations are in
the U.S. and to a lesser extent Europe.

  The accounting policies of the segments are the same as those described in
Note 3 under "Summary of Significant Accounting Policies". Ziff-Davis Inc.
evaluates the performance of its segments and allocates resources to them based
on EBITDA. Any inter-segment revenue included in segment data are not material.
The following presents information about the reported segments for the years
ending December 31:

 Interest rate swaps

  Ziff-Davis Inc. utilizes interest rate swaps to reduce the impact on interest
expense of fluctuating interest rates on its variable rate debt. Under Ziff-
Davis Inc.'s interest rate swap agreements, Ziff-Davis Inc. agreed with the
counterparties to exchange, at quarterly intervals, the difference between
Ziff-Davis Inc.'s fixed pay rate and the counterparties' variable pay rate on
three-month LIBOR. At December 31, 1998, Ziff-Davis Inc. was a fixed payor of
5.85% on an aggregate notional amount of $550,000,000.

  The fair values of these interest rate swaps were estimated by obtaining
quotes from brokers which represented the amounts that Ziff-Davis Inc. would
pay if the agreements were terminated at the balance sheet date. While it is
not Ziff-Davis Inc.'s intention to terminate these interest rate swaps, these
fair values indicated that the termination of the interest rate swap agreements
would have resulted in a loss of $15,627,000.

21. Subsequent Events

 ZDTV

  On February 4, 1999, Ziff-Davis Inc. purchased ZDTV at a purchase price of
approximately $81,400,000. (See Note 12.) Ziff-Davis Inc. paid approximately
$32,800,000 of the purchase price in cash (settled on February 5, 1999) and
paid the remainder by applying approximately $48,600,000 in advances owed to it
by MAC Holdings America. Ziff-Davis Inc. also agreed to be responsible for the
funding of ZDTV during the period in 1999 prior to the purchase which will be
accounted for as additional purchase price. Other than advances to ZDTV which
are reported on Ziff-Davis Inc.'s balance sheet, the results of operations of
ZDTV are not included in Ziff-Davis Inc.'s results for any of the periods
presented. This acquisition will be accounted for in 1999 under the purchase
method of accounting.

Programming had been consummated on January 1, 1998. Adjustments for ZDTV
transactions include the operating results of ZDTV, amortization of the
purchase price of ZDTV, Vulcan Programming's one-third interest in the losses
of ZDTV and the tax effects of these items. The pro forma data is not
necessarily indicative of actual results had the transaction occurred on

exercise that option for 30 days. If any shares are purchased pursuant to this
option, the U.S. underwriters will severally purchase shares in approximately

  Shares sold by the U.S. underwriters to the public will initially be offered
at the initial public offering price set forth on the cover of this prospectus.
Any shares sold by the U.S. underwriters to securities dealers may be sold at a
discount of up to $0.80 per share from the initial public offering price. Any
such securities dealers may resell any shares purchased from the underwriters
to certain other brokers or dealers at a discount of up to $0.10 per share from
the initial public offering price. If all the shares are not sold at the
initial offering price, the representatives may change the offering price and
the other selling terms.

  Goldman Sachs International, Donaldson, Lufkin & Jenrette International and
Hambrecht & Quist LLC have entered into an underwriting agreement with the
underwriters for the offering of 2,000,000 shares outside of the United States.
The terms and conditions of the offering in the United States and the
international offering outside of the United States are the same and the sale
of shares in both offerings are conditioned on each other.
  Goldman Sachs International, Donaldson, Lufkin & Jenrette International and
Hambrecht & Quist LLC are representatives of the underwriters for the
international offering outside the United States. We refer to the U.S.
underwriters and the International underwriters as the underwriters.

  The underwriters have entered into an agreement in which they agree to
restrictions on where and to whom they and any dealer purchasing from them may
offer shares as a part of the distribution of the shares. The underwriters also
have agreed that they may sell shares among each of the underwriting groups.

  Ziff-Davis Inc. has agreed with the underwriters not to dispose of or hedge
any of its ZDNet stock or securities convertible into or exchangeable for
shares of ZDNet stock during the period from the date of this prospectus
continuing through the date 180 days after the date of this prospectus, except
with the prior written consent of the representatives. This agreement does not
apply to any existing employee benefit plans. See "Shares Eligible for Future
Sale" for a discussion of this agreement and certain other transfer
restrictions.

  In December 1998, Donaldson, Lufkin & Jenrette Securities Corporation
acquired 30,000 shares of Ziff-Davis Inc. common stock for a purchase price of
$330,000. These shares may be deemed to be underwriters' compensation to
Donaldson, Lufkin & Jenrette in connection with the offering, and, in
accordance with the Rules of the NASD, Donaldson, Lufkin & Jenrette has agreed
not to sell, transfer, assign or hypothecate such shares for one year following
the effective date of the offering.

  In March 1999, Goldman, Sachs & Co. acted as the exclusive private placement
agent for SOFTBANK Kingston in connection with the private placement of shares
of Ziff-Davis Inc. common stock to a disinterested third party. Ziff-Davis Inc.
paid customary placement fees to Goldman, Sachs & Co. for such services.

  Prior to the offering, there has been no public market for the shares. The
initial public offering price has been negotiated among Ziff-Davis Inc. and the
representatives. Among the factors considered in determining the initial public
offering price of the shares, in addition to prevailing market conditions, were
Ziff-Davis Inc.'s and ZDNet's historical performance, estimates of the business
potential and earnings prospects of Ziff-Davis Inc. and ZDNet, an assessment of
the management of Ziff-Davis Inc. and ZDNet and the consideration of the above
factors in relation to market valuation of companies in related businesses.

  ZDNet stock has been approved for listing on the NYSE under the symbol "ZDZ".
In order to meet one of the requirements for listing ZDNet stock on the NYSE,
the

                                      U-2
<PAGE>

underwriters have undertaken to sell lots of 100 or more shares to a minimum of
2,000 beneficial holders.

  In connection with the offering, the underwriters may purchase and sell
shares of ZDNet stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering.
Stabilizing transactions consist of certain bids or purchases made for the
purpose of preventing or retarding a decline in the market price of ZDNet stock
while the offering is in progress.

  The underwriters also may impose a penalty bid. This occurs when a particular
underwriter repays to the underwriters a portion of the underwriting discount
received by it because the representatives have repurchased shares sold by or
for the account of such underwriter in stabilizing or short covering
transactions.

  These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of ZDNet stock. As a result, the price of ZDNet stock
may be higher than the price that otherwise might exist in the open market. If
these activities are commenced, they may be discontinued by the underwriters at
any time. These transactions may be effected on the NYSE, in the over-the-
counter market or otherwise.

  The underwriters do not expect sales to discretionary accounts to exceed five
percent of the total number of shares offered.

  Ziff-Davis Inc. estimates that its share of the total expenses of this
offering, excluding underwriting discounts and commissions, will be
approximately $4.2 million.

  At the request of Ziff-Davis Inc., up to 700,000 shares have been reserved
for sale by the U.S. underwriters to employees of Ziff-Davis Inc. and its
affiliates and certain other purchasers. Such shares will be sold at the
initial public offering price and, to the extent sold, will not otherwise be
available for sale as a part of the offering. If any such shares are not sold
in this manner they will be offered by the U.S. underwriters as a part of the
offering.

  Ziff-Davis Inc. has agreed to indemnify the several underwriters against
certain liabilities, including liabilities under the Securities Act.

  This prospectus may be used by the underwriters and other dealers in
connection with offers and sales of the shares, including sales of shares
initially sold by the underwriters in the offering being made outside of the
United States, to persons located in the United States.
